Insertion loss for magnetostatic volume waves

Results were presented earlier for magnetostatic surface waves for wave power, radiation resistance, radiation reactance and insertion loss for multistrip transducers including apodization, variable coupling and two ground planes. Results were also presented for the dispersion relation and group delay for magnetostatic surface waves and magnetostatic volume waves for arbitrary orientation of the external biasing field. Results have now been obtained for forward volume waves and backward volume waves for wave power, radiation resistance, radiation reactance and insertion loss for multistrip transducers including two ground planes, meander line and parallel grating but not including variable coupling. Computer produced graphical results for quantities of interest are presented.
Developmental studies of thalamocortical and commissural connections in the rat somatic sensory cortex

Autoradiographic, axonal degeneration, and horseradish peroxidase fiber tracing methods were employed to investigate the organization, development and potential plasticity of the thalamocortical projection to the somatic sensory cortex of the rat. In the adult animal, thalamocortical terminals are concentrated primarily in layers I and IV and in the upper part of layer VI. Fibers terminating in layers IV and VI arise from a different thalamic region than those terminating in layer I. Discrete clusters of fibers and terminals 250–450 μm wide are distributed only to the parts of the SI cortex containing dense aggregates of layer IV granule cells and not to the intervening, less granular and commissurally connected zones. At birth, thalamocortical fibers have invaded the deep part of the developing SI cortex and are concentrated in the upper part of layer VI. Between the age of two and three days, an additional concentration of fibers appears in the part of the cortical plate which will become layer IV. Layer IV is clearly recognizable by three days of age and the dense granule cell aggregates appear in it no more than one day later. The ingrowth of commissural fibers (Wise and Jones, '76) lags behind that of thalamic fibers. The mature commissural fiber pattern is not established until the age of seven days. After removal of the developing thalamocortical system by thalamotomy in newborn rats, subsequent investigation of the commissural system in the adult showed that no commissural fibers or terminals had invaded either laminae or zones of the cortex deprived of thalamic input. Similarly, commissurotomy at birth was not followed by sprouting of thalamic fibers into zones or laminae deprived of commissural connections. The connectional specificity observed in these neocortical fiber systems contrasts markedly with the plasticity of connections reported in allocortical systems. Removal of thalamocortical afferents before they attain their definitive distribution does not radically effect the overall development of the dense granule cell aggregates in layer IV. Within the aggregates, however, subsidiary features such as the “barrels” fail to appear. This finding suggests that certain elements of cortical architecture such as the dense granule cell aggregates are independent of thalamic afferents while others, such as the barrels, result from the interaction of the developing thalamocortical fibers and/or terminals with maturing neurons.
The theory of the transient state concerning upwelling and coastal current

Upwelling in the Gulf of Mexico and along the coast of California has been treated theoretically by Hidaka for steady-state conditions. An extension of this work is presented which considers the transient state in which upwelling and coastal currents gradually develop in an ocean initially at rest when the wind suddenly begins to blow over the sea surface. Expressions for the component velocity in the x and y directions, for the vertical component, and for the vortieity in the direction of the z axis are derived. A numerical example is included using the expression derived for the x component of the current
Family medicine and primary care internal medicine residents' attitudes toward care of the elderly.

Family medicine and primary care internal medicine residents in a university training program were surveyed about their attitudes toward caring for the elderly. Respondents reported satisfaction with care of the elderly. They considered caring for elderly patients to be medically challenging and reported that they learned an appreciable amount of medicine from elderly patients. The residents were less positive about their impact on elderly patients' health and the quality of care they delivered. Rather than supporting the belief that residents have negative attitudes toward the elderly, the study suggests this group of residents has positive attitudes about caring for this population. Their more negative responses about caring for this population. Their more negative responses about the quality of care they deliver suggest they would be receptive to learning more about delivery of health care to the elderly.
Some characterizations of discrete distributions based on linear regressions of adjacent order statistics

Abstract Let X(1)≤X(2) denote the order statistics of a random sample of size 2 from a discrete distribution taking integer values. We determine classes of such distributions for which the best predictors of X(i), given X(j) and the event {X(2)−X(1)≥m}, namely E(X( i )¦X( j ),X( 2 )−X( 1 )≥m) , is a linear function of X(j), for i≠j where m is a nonnegative integer. This results in new characterizations of the geometric and discrete uniform distributions. The discussion is extended to a larger sample size but is limited to regressions of adjacent order statistics.
Localizing Stationary Targets with Cooperative Unmanned Aerial Vehicles

Abstract Unmanned aerial vehicles (UAVs) play an increasingly important role in a large number of military applications. Frequently deployed for intelligence collection (e.g., surveillance and reconnaissance), they are also useful for establishing long-range communication and providing tactical support. The focus of our research lies on the design and development of autonomous, cooperative UAVs using distributed control, sensing, and communication technologies. In this paper, we present several UAV technologies we developed that enable a team of UAVs to autonomously search, detect, and locate stationary ground targets using airborne sensors. These enabling technologies include: (1) distributed, cooperative control of UAVs, (2) a novel out-of-order sigma-point Kalman filtering method for local fusion of multi-view sensor data collected by different UAVs from varying perspectives, (3) a dynamic air-to-air and air-to-ground communication network, and (4) a UAV operating system to manage control, sensing, and communication activities. We illustrate the capabilities of this cooperative UAV system with test data acquired in flight demonstrations.

Examining the Relationship Between TELPAS Reading and TAKS Reading for Students With Limited English Proficiency

In the performance-driven culture of education today, though arguments regarding the definition of student success abound, few argue its importance. This issue is complicated with an additional dimension for those who are learning English as a second language. For those students who lack proficiency in the English language, academic content must be learned concurrently with the acquisition of the English language. The issue of language acquisition became part of the national education dialogue with the Supreme Court Decision Lau v. Nichols in 1974. It has continued to be a serious issue throughout the country and particularly in the southeast region of Texas. This article will examine how English-language learners (ELLs) are assessed. Specifically, it will focus on the relationship between the standardized academic exam administered to almost all students in Texas and the language acquisition exam for reading administered to almost all ELL students in the state. Furthermore, this article will examine the ...
Comments on ‘On the calculation of surface concentration from the measurement by the radiotracer ‘electrode lowering’ technique’ by D. Poskus

Abstract Quantitative aspects of surface concentration measurements of radiolabeled adsorbates by the thin-gap measuring technique developed by our group have been discussed recently by Poskus (see D. Poskus, J. Electroanal. Chem. 442 (1998) 5). It was argued that surface concentrations obtained by us were underdetermined since the backscattering factor of β-radiation used in our work was too high versus a similar, but more recently obtained value by the quoted author. In response, we have reanalyzed our measuring conditions with a special emphasis on the backscattering phenomena involved in the experiment. Without contradicting the author’s conclusions, the reported results indicate that the backscattering factor used in our formula linking radiation data and surface concentrations was correct. Apparently, in the scintillation-counter mode of the measurements, such a backscattering factor involves a simultaneous detection of reflected light from scintillation events and backscattered β-radiation emitted by the radioactive preparate. Conversely, the Poskus measurements conducted by the use of a gaseous counter determine the second component only. Using a new, experimentally determined backscattering factor and a Au(111) electrode, we present a comparison between sulfate adsorption data obtained by the use of the thin-gap technique and Auger electron spectroscopy and prove, once again, the accuracy of our data.
Temperature Dependence of Shear Modulus, Density, and Crystallinity of Isotactic Poly Polypropylene

Experiments were undertaken to determine the dependence of the shear modulus upon the density and degree of crystallinity of two samples of isotactic polypropylene over a range of temperatures. Annealing the polypropylene samples was found to increase both the shear modulus and the density. Both quantities appeared to be inversely related to the molecular weight of the two polypropylene samples investigated. These phenomena are similar to those observed for polyethylene in our earlier studies. On the other hand, the variation of crystallinity with temperature, as measured by changes in density and by x-ray diffraction, was not the same in polypropylene as in linear polyethylene.
Ceremonial Drinking in an Afro-Brazilian Cult1

T HE present study concerns the use of alcohol by the members of an urban religious cult in northern Brazil. A striking feature of the ideology of this cult is the fiction that it is not the members who drink during the ceremonies, but the deities who possess them. As might be inferred from this belief, there is considerable ambivalence within the cult about drinking, due both to pressures from the larger society and to an awareness that excessive drinking is sometimes disruptive. The purpose of the present paper is to consider the role of drinking in cult activities, and to suggest some of the reasons why drinking continues as a prominent feature of the ceremonies. This will involve the consideration of the functions which drinking serves, not only in cult integration, but especially in possession.
Depression of gastric secretion by a new anticholinergic agent.

The anticholinergic medicationN-ethyl-3-piperidyl-benzilate metho-bromide (Piptal) was studied in 88 patients with elevated and normal gastric secretory patterns. In 77 (88 per cent) of the patients there was a decrease in the output of free acid as compared to the basal hour. In 35 patients (40 per cent) anacidity for 30 minutes or longer was produced.
Classification of chromosomal eye syndromes.

Human chromosome disease arises from a change in the number or structure of one or more chromosomes. The multiple genes represented in the duplicated or deleted chromosomes are not usually defective and any systemic abnormalities can be attributed to a change in gene dosage. Banding techniques are now commonly used to identify each chromosome and the specific chromosome duplication and deletion and structural rearrangements can now be identified unambiguously.
STUDIES IN THE BLOOD CYTOLOGY OF THE RABBIT III. CONSECUTIVE TOTAL WHITE BLOOD CELL OBSERVATIONS ON GROUPS OF NORMAL RABBITS

Consecutive weekly observations on the total white cell count of the peripheral blood were made on 5 groups of normal rabbits, a total of 45 animals, during a period of 20 months from October, 1927 to July, 1929. The duration of individual group examinations varied from 8 to 35 weeks. In the case of 4 groups followed 13 to 35 weeks, the general trend of the total white cell means was toward increasing values; with the group followed 8 weeks, the means were maintained at a constant level. The changes in the levels of the granular cell means were usually accompanied by changes in a similar direction of the non-granular cell means. In the case of 3 of the 4 groups followed for the longest periods, the greatest relative alterations occurred in the non-granular cells. The fluctuations in the mean values of the total white cells and of the granular and the non-granular cells which were observed in one group of rabbits, were also generally observed in another group examined during the same months. The period of greatest irregularity in the mean values of the total white cell means and of the granular and the non-granular cell means as well, occurred during the late winter and spring months of both years. The general level of the total white cell mean values in the groups examined during 1927–28 was higher than that of the groups observed during 1928–29. A similar difference was found in the granular and non-granular mean values but it was somewhat less marked in the case of the granular cells.
Sustainable capital projects: leapfrogging the first cost barrier

Multitudinous strategies, technologies, and best practices exist to improve the sustainability of a capital project, but comparatively few of these tactics have been successfully applied in green building projects without increasing first cost. Given typically constrained budgets available for capital projects, the challenge to project managers, designers, and other project stakeholders is to identify and justify the use of cost-neutral or cost-saving sustainability features that can be included on their projects to meet increasingly stringent sustainability goals set by project owners. The objective of this paper is to identify and describe a set of techniques for finding cost effective sustainability strategies for capital projects. The paper includes a case study of an exemplary capital project from the US to illustrate a set of techniques for identifying cost-neutral or cost-saving project options. These techniques include effective problem framing, identification and exploitation of cost discontinuit...
Consensus interferon used to treat prior partial-responders to pegylated interferon plus ribavirin.

Background The response to pegylated interferon (peg-IFN) plus ribavirin therapy remains less than ideal with 40–50% of treated subjects failing to clear the virus. Moreover, retreatment is only minimally effective. Consensus interferon (c-IFN) has been shown to be efficacious in HCV genotype 1 patients who have failed therapy with peg-IFN.
Immunespecific interferon production by peripheral blood mononuclear leukocytes from patients with primary and recurrent orolabial herpes simplex virus infections

Immune-specific IFN (IFN) is produced by the peripheral blood mononuclear leukocytes (PBML) of greater than 95% of HSV-seropositive humans with infrequent recurrences of herpes labialis [Green, Yeh, and Overall, 1981]. However, herpes virus-induced immune-specific IFN was produced by PBML from only 33 of 48 (68.8%) persons with frequent recurrences (2-12 episodes a year). Two of eight subjects with primary herpes gingivostomatitis also failed to produce immune-specific IFN during either the acute or convalescent phases of their initial HSV infection. These data suggest that some persons have a defective immune-specific IFN response that exists from the time of their primary oro-labial HSV type 1 infection. This defect may predispose to a higher frequency of disease in some individuals.
Surface Dominance in Deep-Inelastic Electron Scattering

Let a finite part of the scaling curve $\ensuremath{\nu}{W}_{2}({\ensuremath{\omega}}^{\ensuremath{'}})$ at low ${\ensuremath{\omega}}^{\ensuremath{'}}$ be locally dual to a set of resonances obeying a mass formula ${{M}_{n}}^{2}=a+{{m}_{0}}^{2}n$. Then it is shown that a simple way of satisfying this condition within the context of several models is that the contributing resonances satisfy the condition $j\ensuremath{\sim}\sqrt{s}$.
On the normal subgroups ofGL(2, A)

In this paper we determine the normal subgroups of GL(2, A) for A a commutative local ring. The papers of Klingenberg [a], Lacroix [3], and our paper [ 1 ] constitute the previous work on this problem. As a consequence of our results, we are able to describe the normal subgroups of GL(2, A) for all Artinian rings A; hence, in particular, for all finite rings A. If N is a subset of GL(2, A), we denote by I(N) the level ideal of N, that is, the smallest ideal of A such that N consists of scalar matrices modulo I(N). For J an ideal of A, GC(2, A; J) = { TE GL(2, A) 1 I(T) E J> is the normal subgroup consisting of all matrices which are scalars modulo J, while SL(2, A; J) = { TE GL(2, A) 1 det T= 1 and Tz Imod J> is the principal congruence subgroup for J. Klingenberg proved that if i E A and the residue field of A is not G8’(3), then a subgroup N of GL(2, A) is normal if and only if SL(2, A; Z(N)) EN. Equivalently, N is normal if and only if SL(2, A; J) E Nc GC(2, A; J) for some ideal J, in which case J= Z(N). His paper also shows that this criterion for normality holds in GL(n, A) for n > 3 without any hypotheses on the local ring A. Our paper [ 1 ] characterizes normal subgroups of GL(2, A) for any %,-ring A with $6 A. Since every local ring is an SR,-ring, this leaves only the case of local rings in which 2 is not a unit, i.e., in which the residue field has characteristic 2. Lacroix, in [3], deals with local rings in which the residue field has characteristic 2 but is not GI;(2), obtaining the same normality criterion as Klingenberg. This leaves open the case of local rings with residue field GE(2). We shall use the “method of reduction” employed in Cl] to give a normality criterion for subgroups of GL(2, A) for A a local ring with GJ’(2) as residue field. Moreover, the method will allow us to recapture the results of Klingenberg and Lacroix with great efficiency. Thus, we will be able to 395 0021~8693/90 $3.00
General Music in Secondary Schools: Beyond the Performing Arts.

What is general music? Why should general music be a part of the sec ondary school curriculum? In light of AMERICA 2000, President Bush and the governors' strategy for improving education, how can general music help prepare students for the year 2000?
There's a mouse in the house.

A total of 82% of US homes had detectable mouse allergen levels. In 35% of homes, the MUP level exceeded 1.6 μg/g of dust, a level associated with increased rates of mouse sensitization. In individuals with reported allergic disease, MUP levels greater than 1.6 μg/g were associated with an increased risk of asthma symptoms (OR, 1.93; 95% CI, 1.14–3.27), but not in those who were not allergic to any allergens.
Measurements of OH − absorption and proton activation in Pb 1 − x Ba x Nb 2 O 6 crystals with applications to holographic storage

${\mathrm{Pb}}_{1\ensuremath{-}x}{\mathrm{Ba}}_{x}{\mathrm{Nb}}_{2}{\mathrm{O}}_{6}$ is a material under consideration for electro-optic and photorefractive applications. Single crystals of ${\mathrm{Pb}}_{1\ensuremath{-}x}{\mathrm{Ba}}_{x}{\mathrm{Nb}}_{2}{\mathrm{O}}_{6}$ have been grown using the vertical Bridgman method in the composition range $0.5l1\ensuremath{-}xl0.6.$ The formation and thermal fixing of holographic gratings in these crystals were recently demonstrated. In this study the ${\mathrm{OH}}^{\ensuremath{-}}$ absorption spectra were measured by fourier-transform infrared spectrometry. As-grown crystals showed a strong ${\mathrm{OH}}^{\ensuremath{-}}$ absorption near $\ensuremath{\nu}=3485{\mathrm{cm}}^{\mathrm{\ensuremath{-}}1},$ revealing the existence of protons $({\mathrm{H}}^{+})$ which are essential for the thermal fixing of holograms. The dependence of the integrated ${\mathrm{OH}}^{\ensuremath{-}}$ optical-absorption intensity on polarization showed that all of the O-H bonds were polarized either perpendicular or parallel to the $c$ axis, with a greater proportion perpendicular. The proton concentration could be increased by heat treatment in a humid atmosphere and decreased in an ambient or oxygen atmosphere. The diffusivity of protons perpendicular to the $c$ axis was measured in ${\mathrm{Pb}}_{0.5}{\mathrm{Ba}}_{0.5}{\mathrm{Nb}}_{2}{\mathrm{O}}_{6}$ by proton in-diffusion experiments and was found to be ${D}_{0}\ensuremath{\approx}0.219\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}{\mathrm{cm}}^{2}/\mathrm{s}$ at 750 \ifmmode^\circ\else\textdegree\fi{}C, which is comparable to the proton diffusivity in ${\mathrm{TiO}}_{2}$ ${(D}_{0}\ensuremath{\approx}0.190\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}{\mathrm{cm}}^{2}/\mathrm{s})$ and ${\mathrm{LiNbO}}_{3}$ ${(D}_{0}=0.193\ensuremath{\sim}2.507\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}{\mathrm{cm}}^{2}/\mathrm{s})$ at the same temperature. Measurements of the thermal decay of holograms showed that the proton activation energy, $\ensuremath{\Delta}E,$ in ${\mathrm{Pb}}_{0.5}{\mathrm{Ba}}_{0.5}{\mathrm{Nb}}_{2}{\mathrm{O}}_{6}$ was $0.95\ifmmode\pm\else\textpm\fi{}0.05\mathrm{eV},$ which is close to the proton activation energies reported for ${\mathrm{LiNbO}}_{3}$ and ${\mathrm{KNbO}}_{3},$ 1.10\char21{}1.40 eV and 0.81\char21{}1.04 eV, respectively.
Progressive and Recurrent Nonarteritic Anterior Ischemic Optic Neuropathy

We examined ten patients with nonarteritic anterior ischemic optic neuropathy in whom the visual deficit progressed over a number of weeks or who suffered a recurrence in the same eye. The visual deficits progressed over a month or more in five patients, four patients suffered a recurrence in the same eye after a long interval, and one patient had bilateral progression and a recurrence.
Case report: atypical presentation of jugular foramen mass

Abstract Introduction Jugular foramen lesions are often associated with pathology of adjacent structures due to either compression or direct invasion. Common presenting symptoms include pulsatile tinnitus, a neck mass, hearing loss, and cranial nerve palsies, leading to changes in taste, vocal cord paralysis, dysphagia, and sternocleidomastoid/trapezius weakness (A. Hakuba, K. Hashi, K. Fujitani, et al., Jugular foramen neurinomas. Surg Neurol 1979; 11:83-94). This patient was found to have a jugular foramen mass after presenting with the unusual constellation of visual changes and headache. Case presentation A jugular foramen mass in a young woman was discovered after presenting with visual changes and headache; the patient was found to have papilledema on initial examination. Otologic and head and neck examination were normal. Subsequent imaging demonstrated a mass at the right jugular foramen with compression of this structure; a contralateral transverse sinus stenosis was also seen. This latter abnormality (along with obstruction of the jugular foramen) impeded venous drainage leading to papilledema and visual changes. Discussion In a patient presenting with papilledema and severe headache with an associated jugular foramen mass, a multidisciplinary approach benefits the patient with input from interventional neuroradiology, neurosurgery, and neuro-ophthalmology. Venous outflow was compromised through the left stenotic transverse sinus, and the normal outflow on the right side through the jugular bulb was impeded by the tumor; obstructions of both led to symptomatic impeded venous outflow. This compromise in venous outflow led to an increase in superior sagittal sinus pressure, with subsequent increase in intracranial pressure and resultant papilledema. In an attempt to increase blood flow, an angioplasty was performed on the patient's affected transverse sinus. In addition, symptomatology consistent with pseudotumor cerebri prompted the use of acetazolamide for medical management. After both therapies, the patient's symptoms dramatically improved and were stable. The tumor has also remained stable, with no immediate need for surgical resection, stereotactic radiation, or consideration of an intraluminal transverse sinus stent placement or shunting. Conclusion The unique presentation of a jugular foramen mass in a young woman leading to papilledema highlights the need for high clinical suspicion of potential etiologies necessary for diagnosis. Despite the benign nature of her disease process, an unusual constellation of anatomical factors lead to the need for acute intervention.
Use of Multiple-Site Performance-Contingent SEMG Reward Programming in Pediatric Rehabilitation: A Retrospective Review

We completed a retrospective review of the effectiveness of multi-site, performance-contingent reward programming on functional change in motor performance of 16 treatment resistant children. Patients were previously treated in physical or occupational therapy for head control, standing balance training, sitting and upper extremity use (brachial plexus injury). They then participated in a program that utilized multiple surface electromyography sites the use of which was rewarded with videos for performing the correct constellation of recruitment pattern (e.g., contracting some muscles while relaxing others). Onset of reward was calibrated for each patient and transfer of skill to outside the clinic was encouraged by linking a verbal cue to the correct motor plan. Fourteen of the 16 patients improved. The implications of the use of this technique in the treatment of motor dysfunction is discussed.
Automation and education: II. Automatizing the classroom-background of the effort

This paper has attempted to deal with two aspects of the problem of automatizing the classroom through audio-visual means. These aspects were: (a) the institutional background in which the earlier foundation support of the audio-visual movement by the Payne Fund and the Rockefeller Foundation was compared to the present, much more extensive support of the mass audio-visual approach to teaching supported by the Ford Foundation, its several Funds and the organizations which it underwrites; and (b) the theoretical position requiring audio-visual automation which was shown to be based on the teacher and plant shortage facing this country in the next two decades of swelling school and college enrollments and, therefore, necessitating technological solutions to problems of class size and building space.
Immediate hemodynamic effects of thrombolytic therapy on the ischemic myocardium

Thrombolytic agents are used to restore coronary artery perfusion and limit the size of a myocardial infarction. The systemic effects of these drugs, streptokinase (SK), urokinase (UK), and recombinant tissue plasminogen activator (rtPA), have been studied extensively. Although their effects on rheology and late myocardial performance have been well-documented to date, there have not been any studies evaluating the acute hemodynamic consequences of thrombolytics immediately after administration. In this report we use an isolated Langendorf rodent heart preparation to evaluate the acute hemodynamic effects of thrombolytic therapy on both the normal and the ischemic myocardium. We quantified performance by documenting cardiac output, coronary blood flow, and blood pressure. Although each thrombolytic agent significantly transiently impairs cardiac performance, differences in effect between the agents were statistically insignificant. This was also the case with both the normal as well as the ischemic myocardium. The results of this study would not support favoring the use of one of these agents over the other with regards to primary myocardial performance.
Development of adaptive instrumentation for process control

This abstract describes the operation of an automated electrochemical cell that utilizes an ion selective electrode (ISE) as the detector. The instrument can rapidly and automatically generate on-line estimates of the concentration of an ion, thus providing chemical information useful for controlling a chemical process. A typical application might be the monitoring of a sewage treatment plant to facilitate control of the concentration of a contaminant in discharged water.
Macular Abnormalities in Papilledema from Pseudotumor Cerebri

Three young women with papilledema secondary to pseudotumor cerebri evolved mottled macular pigmentation with preservation of normal visual acuity. Choroidal folds or macular star figures were observed. These macular changes could represent the sequelae of either macular edema or a mechanical disruption of the retinal pigment epithelium. The mechanism of choroidal folds in papilledema remains uncertain.
Aripiprazole augmentation of selective serotonin reuptake inhibitors for treatment-resistant major depressive disorder.

Background Due to their favorable side effect profile, atypical antipsychotic agents offer important therapeutic advantages in mood disorders. Aripiprazole, an atypical antipsychotic agent with partial dopaminergic and serotonin 1A receptor agonist activity, may be particularly useful when used in conjunction with standard antidepressants in treatment-resistant depression. The purpose of this study was to test this hypothesis in depressed outpatients who have not experienced significant clinical improvement following an adequate trial of a selective serotonin reuptake inhibitor (SSRI). Method 12 patients (mean +/- SD age = 46.6 +/- 11.3 years, 66.7% female) with major depressive disorder (MDD) diagnosed by use of the Structured Clinical Interview for DSM-IV-Axis I Disorders, who had failed to experience a clinical response following an adequate trial of an SSRI, were treated with open-label aripiprazole in addition to their SSRI for 8 weeks. Clinical response was defined as a 50% or greater decrease in depressive symptoms during the course of the trial (baseline-endpoint) as measured by the 17-item Hamilton Rating Scale for Depression total score. Data were collected from August 2003 to July 2004. Results 9/12 (75.0%) patients completed the trial. Using a completer analysis, 5/9 (55.6%) patients were classified as responders. An intent-to-treat (ITT) analysis resulted in 7 responders (58.3%). The overall proportion of remitters was 3/9 (33.3%) using a completer analysis and 5/12 (41.7%) using the ITT analysis. Aripiprazole administration appeared safe, with no severe adverse events observed in any of the study participants. Conclusions These results suggest a possible augmentation role for aripiprazole when used in conjunction with SSRIs in SSRI-resistant MDD.
Intramolecular trapping of an ylide intermediate in the reaction of 1:CH2 with an allylic alcohol

Abstract The reaction of 1 :CH 2 , generated by the photolysis of CH 2 N 2 , with 2-methyl-3-buten-2-ol leads to the formation of several products including 4-methyl-3-penten-1-ol. This product is best explained as the result of rearrangement of an ylide intermediate.
Androgen, estrogen, and progesterone receptors in normal and aging prostates

Testicular hormones regulate the growth and development of the prostate. The presence of androgen receptors in prostatic tissue and their importance in the normal development of the prostate has been established. Age-related changes in the hormonal milieu, and perhaps steroid hormone receptor profile, could set in motion pathological changes leading to the onset of benign prostatic hyperplasia (BPH) or prostate cancer which primarily affect older men. The accumulation of dihydrotestosterone with age, the reawakening of the inductive potential of the prostatic stroma, the altered rate of apoptosis with age, and the age-related changes in the ratio of testosterone: estrogen have all been implicated in the etiology of BPH. In addition to androgen receptors, several studies have documented the presence of estrogen and progesterone receptors in BPH and prostate cancer. So far, most studies have focussed on the correlation between the presence/absence of steroid hormone receptors and response to hormonal therapy. The molecular mechanisms by which these steroid hormone receptors regulate the onset or progression of BPH and prostate cancer are not yet clear. The chronological changes in the levels and distribution of steroid hormone receptors in normal prostatic tissue and the effect of such changes on the synthesis of growth factors, growth factor receptors, and oncogenes should be investigated. © 1995 Wiley-Liss, Inc.
RF performance of short channel graphene field-effect transistor

We have experimentally demonstrated the high performance short channel RF graphene device with cut-off frequency of 170 GHz on epitaxial graphene on SiC. We have also studied performance improvement by reducing contact resistance at lower measurement temperature for short channel device. The study shows continuous performance improvement can be achieved by proper channel length scaling and structure optimization such as self-aligned gate and technological solutions for contact resistance reduction.
Practical management of venous injury during pelvic surgery for urologic disease.

Abstract There is a selection of techniques (ligation, lateral suture repair, venous patch graft, end to end repair, and vein replacement graft) which can be adopted to deal with venous injury during pelvic surgery for urologsc disease. Technical details of the various methods of repair are described for the benefit of the urologist who occasionally finds himself with a major venous injury and no vascular surgeon available to help.
An optimal convex hull algorithm in any fixed dimension

We present a deterministic algorithm for computing the convex hull ofn points inEd in optimalO(n logn+n?d/2?) time. Optimal solutions were previously known only in even dimension and in dimension 3. A by-product of our result is an algorithm for computing the Voronoi diagram ofn points ind-space in optimalO(n logn+n?d/2?) time.
Using The Filter Bubble to Create a Teachable Moment: A Case Study Utilizing Online Personalization to Engage Students in Information Literacy Instruction

Engaging students in information literacy instruction is often a challenge. The authors discuss ways they adapted information literacy instruction at York College of Pennsylvania based on concepts discussed in Eli Pariser’s book, The Filter Bubble. By approaching the students with a course theme that was interesting, timely, and personally relevant, the authors were able to break through student’s own filters to explore higher level information literacy concepts and critical thinking. Students took a personal interest in the topic, which translated into greater student engagement and increased participation. It also fostered deeper reading and reflection about how information is communicated and used by a variety of audiences.
Scene classification and segmentation using multispectral sensor fusion implemented with neural networks

SUMMARYResults indicate that the modified LVQ network and multilayer backpropagation network bothserve well as automated algorithms for processing combined multispectral sensor data for classifying atarget vehicle, building, paved road, trees, and grass within a scene. Using the same networks todistinguish only two classes, targd and background, these algorithms do an excellent job of targsegmentation. In this capacity, a neural network could be used for segmentation preprocessing ord,ection prior to implementing follow-on feature extraction and classification algorithms if spatial orother recognition processing is required. To a lunited degree, networks were also tested for classification robustness on shadowed and unshadowed regions as well as variations throughout thediurnal cycle. 7.

A Survey Analysis Suggests That Electronic Health Records Will Yield Revenue Gains For Some Practices And Losses For Many

Health care providers remain uncertain about how they will fare financially if they adopt electronic health record (EHR) systems. We used survey data from forty-nine community practices in a large EHR pilot, the Massachusetts eHealth Collaborative, to project five-year returns on investment. We found that the average physician would lose $43,743 over five years; just 27 percent of practices would have achieved a positive return on investment; and only an additional 14 percent of practices would have come out ahead had they received the $44,000 federal meaningful-use incentive. The largest difference between practices with a positive return on investment and those with a negative return was the extent to which they used their EHRs to increase revenue, primarily by seeing more patients per day or by improved billing that resulted in fewer rejected claims and more accurate coding. Almost half of the practices did not realize savings in paper medical records because they continued to keep records on paper. We...

The Case Against Separate Schools.

small group discussions and reports. This survey illustrates that many middle school, junior high, and secondary teachers are incorporating science fiction into their classroom instructional programs. In many respects, science fiction is interdisciplinary in nature and provides a common base for analyzing difficult problems of the present and the future. Science fiction, because of its mass recognition through television, films, and writings has come of age and because of this popularity, it has touched on almost every subject involving social awareness. It is highly conceivable that teachers at these grade levels will continue to capitalize on the positive benefits of science fiction as a part of the 7-12 curriculum. NOTES
Supporting semantic visual feature browsing in contentbased video retrieval

A new shot level video retrieval system that supports semantic visual features (e.g., car, mountain, and fire) browsing is developed to facilitate content-based retrieval. The video's binary semantic feature vector is utilized to calculate the score of similarity between two shot keyframes. The score is then used to browse the "similar" keyframes in terms of semantic visual features.
Molecular analysis of chromium and cobalt-related toxicity

Occupational and environmental exposure to Co and Cr has been previously linked to a wide array of inflammatory and degenerative conditions and cancer. Recently, significant health concerns have been raised by the high levels of Cr and Co ions and corrosion products released by biomedical implants. Herein, we set to analyze the biological responses associated with Co and Cr toxicity. Histological, ultrastructural, and elemental analysis, performed on Cr and Co exposed patients reveal the presence of corrosion products, metallic wear debris and metal ions at varying concentrations. Metallic ions and corrosion products were also generated in vitro following macrophage phagocytosis of metal alloys. Ex vivo redox proteomic mapped several oxidatively damaged proteins by Cr(III) and Co(II)-induced Fenton reaction. Importantly, a positive correlation between the tissue amounts of Cr(III) and Co(II) ions and tissue oxidative damage was observed. Immobilized- Cr(III) and Co(II) affinity chromatography indicated that metal ions can also directly bind to several metallo and non-metalloproteins and, as demonstrated for aldolase and catalase, induce loss of their biological function. Altogether, our analysis reveals several biological mechanisms leading to tissue damage, necrosis, and inflammation in patients with Cr and Co-associated adverse local tissue reactions.
Phospholipid bilayer formation on a variety of nanoporous oxide and organic xerogel films.

Lipid bilayers supported by nanoporous xerogel materials are being explored as models for cell membranes. In order to better understand and characterize the nature of the surface–bilayer interactions, several oxide and organic nanoporous xerogel films (alumina, titania, iron oxide, phloroglucinol–formaldehyde, resorcinol–formaldehyde and cellulose acetate) have been investigated as a scaffold for vesicle-fused 1,2-dioleoyl-glycero-3-phosphocholine (DOPC) lipid bilayer formation and mobility. The surface topography of the different substrates was analyzed using contact and tapping-mode atomic force microscopy and the surface energy of the substrates was determined using contact angle goniometry. Lipid bilayer formation has been observed with fluorescence microscopy and lateral lipid diffusion coefficients have been determined using fluorescence recovery after photobleaching. Titania xerogel films were found to be a robust and convenient support for formation of a two-phase DOPC/1,2-distearoyl-glycero-3-phosphocholine bilayer and domains were observed with this system. It was found that the cellulose acetate xerogel film support produced the slowest lipid lateral diffusion.
Evaluating the role of motor regulation in figural fluency: Partialing variance in the Ruff Figural Fluency Test

Figural fluency is often thought to assess the ability to "think fluently and flexibly in the visual-spatial mode" (Ruff, 1988). However, the contribution of motor regulation to the performance of this task has not been previously examined. The goal of this study was to evaluate the potential relationship between motor sequence fluency (without a visual-spatial component) and figural fluency. A total of 55 participants (ages 18 to 68 years) were administered (a) the Ruff Figural Fluency Task (RFFT), (b) the Trail Making Test Part B (TMT-B), which overlaps with the RFFT in visual tracking and graphomotor demands, (c) an electronically administered Motor Sequence Fluency Test (MSFT), which overlaps with the RFFT in generation of novel hand movements in the absence of visual stimuli, and (d) a Complex Motor Programming Task. Hierarchical regression analyses were used to determine whether complex motor programming uniquely contributes to RFFT performance above and beyond the processes that are traditionally assumed to be required, as well as to determine whether the ability to generate novel motor sequences uniquely contributes to RFFT performance. Age and education were also added to the regression models in order to determine the contribution of demographic variables to the current findings. Results indicated that age, specific components of motor programming, and nonvisual motor generative fluency represent the most prominent predictors of RFFT performance. Consequently, the role of motor regulation and motor flexibility may in fact be more important for RFFT performance than previously thought, whereas visual-spatial processing may play a lesser role.
Medial prefrontal cortex activity can disrupt the expression of stress response habituation

Recent findings suggest that the expression of hypothalamic-pituitary-adrenal (HPA) axis stress response adaptation in rats depends on top-down neural control. We therefore examined whether the medial prefrontal cortex (mPFC) modulates expression of stress response habituation. We transiently suppressed (muscimol microinfusion) or stimulated (picrotoxin microinfusion) mPFC neural activity in rats and studied the consequence on the first time response to psychological stress (restraint) or separately on the development and expression of habituation to repeated restraint. We monitored both the hormonal (corticosterone) and neural (forebrain c-fos mRNA) response to stress. Inactivation of the mPFC had no effect on the HPA-axis response to first time restraint, however increased mPFC activity attenuated stress-induced HPA-axis activity. In a three day repeated restraint stress regimen, inactivation of the mPFC on days 1 and 2, but not day 3, prevented the expression of HPA-axis hormone response habituation. In these same rats, the mPFC activity on day 3 interfered with the expression of c-fos mRNA habituation selectively within the mPFC, lateral septum and hypothalamic paraventricular nucleus. In contrast, inactivation of the mPFC only on day 3, or on all 3 days did not interfere with the expression of habituation. We conclude that the mPFC can permit or disrupt expression of HPA-axis stress response habituation, and this control depends on alteration of neural activity within select brain regions. A possible implication of these findings is that the dysregulation of PFC activity associated with depression and post-traumatic stress disorder may contribute to impaired expression of stress-response adaptation and consequently exacerbation of those disorders.
Quasi-Coherent Thermal Emission in the Terahertz by Doped Semiconductors

We investigate thermal emission characteristics mediated by surface plasmon polaritons (SPPs) resonantly excited at a semiconductor-vacuum interface. The characteristic plasma and SPP resonant frequencies in the interval from 0.3 to 10 THz can be controlled with conventional doping densities. All of the cases under consideration (n-doped GaAs, GaN, and Si) demonstrate the spectral energy density in the near field that is several orders of magnitude larger than the blackbody radiation. The strongly resonant SPPs are also shown to enhance drastically the radiative heat transfer between two semi-infinite surfaces separated by nanometric distances. The possibility of extending spatially coherent emission through 1-D binary grating is examined based on a rigorous coupled-wave analysis. Our calculation results clearly indicate that n-doped semiconductors with properly designed surface grating can achieve efficient directional thermal emission in the THz frequency range for potential use in a number of applications including sensing.
Religious Affiliation and Hiring Discrimination in the American South A Field Experiment

This article describes a field experiment in which we sent fictitious resumes to advertised job openings throughout the American South. We randomly altered the resumes to indicate affiliation in one of seven religious groups or a control group. We found that applicants who expressed a religious identity were 26 percent less likely to receive a response from employers. In general, Muslims, pagans, and atheists suffered the highest levels of discriminatory treatment from employers, a fictitious religious group and Catholics experienced moderate levels, evangelical Christians encountered little, and Jews received no discernible discrimination. We also found evidence suggesting the possibility that Jews received preferential treatment over other religious groups in employer responses. The results fit best with models of religious discrimination rooted in secularization theory and cultural distaste theory. We briefly discuss what our findings suggest for a more robust theory of prejudice and discrimination in society.
