The effect of a potential-sensitive barbituric acid molecular probe on the thermal phase transition properties of multilamellar 1,2-dimyristoyl-sn-glycero-3-phosphocholine suspensions

Abstract The interaction of the extrinsic, potential-sensitive probe diBa-C 2 -(5) with 1,2 dimyristoyl- sn -glycero-3-phosphocholine (DMPC) in the form of unilamellar vesicles or as multilamellar suspensions has been characterized by probe-membrane binding studies and differential scanning calorimetry. The presence of diBa-C 2 -(5) in DMPC suspensions lowers the temperature at the midpoint of the gel-to-liquid-crystalline phase transition T m by a maximal 0.15°C. The enthalpy of the gel-to-liquid-crystalline phase transition is reduced by a maximal 4%, whereas that of the pre-transition is unaffected by the presence of 5 mol% diBa-C 2 -(5). The cooperativity of the gel-to-liquid-crystalline phase transition is reduced by a maximal 35%. When present at a concentration of 5 mol%, this indicator causes virtually no change in the pre-transition cooperativity. The diBa-C 2 -(5)/DMPC system can be described by the ideal solution theory when the probe is present at a concentration of ≤0.2 mol%. Non-ideal behavior of the diBa-C 2 -(5)/DMPC system is observed at concentrations >0.2 mol% probe. DiBa-C 2 -(5) mildly perturbs the membrane in comparison to the effects of most other potential-sensitive probes, and is probably located at or near the surface of the bilayer.
Narrowband ultrasonic phased array control using a photonic beamformer

Abstract A novel narrowband photonic beamformer for ultrasonic phased array control is proposed and demonstrated. The dual Bragg cell in-line optical design allows for the use of radio frequency Bragg cells for stable low frequency (DC-15 MHz) signal generation for driving ultrasonic arrays. Two tiny stamp size nematic liquid crystal devices provide the sites for signal phase (0–2π) and amplitude control. The proof-of-principle beamformer demonstrated 0–2π phase control and 55.8 dB gain control for a 10 MHz output signal that showed a carrier-to-noise ratio of 108 dB Hz−1 at + 100 kHz offset. Both continuous and pulsed mode beamformer operation are demonstrated. Features of the photonic beamformer include analog control, wide tuning range, fiber remoting, size/weight advantages, and low control power operation.
The Secret Heroine of Mark's Drama

Mark is a gospel of secrets that gradually unfold to the audience. This becomes more evident in light of recent studies of Mark as a narrative drama. In such a drama, Jesus, especially in his hero's death, is the center of the gospel. However, his counterpart is the ideal disciple who follows him as far as the cross. Mark presents this ideal disciple portrait in a gradually expanding dramatic crescendo through key women presented in the gospel. The climactic ending comes in the Bethany woman's prophetic action and its completion in Mary Magdalene, especially, and the other women who obey Jesus' initial command, "Follow me," as far as the cross. Thus, they make possible the "preaching of the gospel in the whole world" as a necessary prerequisite for the return of Jesus.
PAMSys: long-term physical activity monitoring with single wearable motion sensor

In this demo, we present PAMSys™(physical activity monitoring system), a single body sensor solution for long-term and continuous monitoring of a person's daily activities. PAMSys™ requires only a single light-weight sensor unit that can be integrated unobtrusively into a comfortable shirt (or directly to a subject's shirt) without hindering daily-living activities. The use of large flash storage and low power sensor technologies allows a maximal system lifetime of 8 days on a single charge, minimizing the management burden of the users of the system. PAMWare™, the data analysis software for PAMSys™, performs advanced biomechanical analyses on the tri-axial accelerometer signals recorded by the sensor unit and generates a detailed report on the subject's postural information throughout the entire measurement period. The system can be used for monitoring the state of health in the elderly, as well as the effect of different medical and surgical procedures in enhancing a patients' quality of life. As an example, long-term physical activity data can be applied to assess the risk of fall for elderly people by monitoring durations of sit-to-stand posture transitions.
Construction, overexpression, and purification of Arthrobacter globiformis amine oxidase-Strep-tag II fusion protein.

The copper-containing amine oxidase from Arthrobacter globiformis has been expressed and purified as a fusion protein with a C-terminal Strep-tag II peptide. This tag facilitates the rapid purification of the enzyme on a large scale using the StrepTactin POROS medium. For example, we have demonstrated that 50 mg of protein can be obtained in 2 days from 2 L of Escherichia coli. The purified fusion protein displays turnover and spectroscopic properties that are essentially identical to those of the wild-type enzyme. Given the location of the C-terminus in four amine oxidase crystal structures, this strategy should be quite general for the rapid purification of amine oxidases from multiple sources.
Electron-temperature dependence of the recombination of H3O+(H2O)n ions with electrons

The T(e) dependence of the recombination of H3O+(H2O)n cluster-ions with electrons has been measured in an afterglow experiment in which the electrons were heated by a radio-frequency electric field. The recombination coefficients were found to vary with T(e) as about T(e) exp -1/2 in better agreement with theoretical expectations than earlier results of microwave-afterglow measurements.
Final-state potential in x-ray spectra

An examination is made of the one-electron theory of x-ray transitions in metals. A question is raised whether the one-electron theory should be calculated using the potential of the central atomic core which does, or does, not, include the screened core hole. It is suggested that one should use the potential of the final state, which has the core hole in absorption and not in emission. This suggestion agrees with emission data, as well as Mahan-Nozi\`eres-De Dominicis theory which is solved numerically for a square-well potential.
Experimental studies on flotation column dynamics

Abstract Flotation columns have been widely used in mineral processing all over the world. They have been systematically incorporated in a lot of mills, specially as a final cleaning stage. However, they differ in many aspects from conventional flotation cells. Different physical dimensions of collection and froth zones, different ways of generating and distributing the air bubbles in the system and the new use of wash water on the top of the froth, pose different control problems and opportunities. New operational variables, with different variability and relationships among them, demand new efforts in better process variable measurements, models development and control strategies of flotation columns. Most of the actual installations still use conventional instrumentation and conventional distributed PI control. Improvements in operation and control of flotation columns can be achieved by a better knowledge of its dynamics. In the literature some phenomenological model developments have been reported, but a rather large number of model parameters have to be estimated from experimental data. In this work an experimental study of the dynamic behaviour of two flotation columns at different scales is presented. A 5 × 10 cm rectangular section and 1.35 m high laboratory scale column and a 10 cm diameter and 8.5 m high pilot scale column were used to obtain dynamic relationships for the air-water system. Field instrumentation was installed and calibrated, and data signals communicated to a PC computer through a serial A/D/A interface. Changes in gas, wash water and feed flowrates, and tailing valve opening were specially designed and carried out to obtain experimental responses of pulp level, gas holdup and bias, at different operating conditions. Main nonlinearities and interactions were shown to be very useful to explain common control problems.
Switchable dual-wavelength SOA-based fiber laser with continuous tunability over the C-band at room-temperature

We propose and demonstrate a simple compact, inexpensive, SOA-based, dual-wavelength tunable fiber laser, that can potentially be used for photoconductive mixing and generation of waves in the microwave and THz regions. A C-band semiconductor optical amplifier (SOA) is placed inside a linear cavity with two Sagnac loop mirrors at its either ends, which act as both reflectors and output ports. The selectivity of dual wavelengths and the tunability of the wavelength difference (Δλ) between them is accomplished by placing a narrow bandwidth (e.g., 0.3 nm) tunable thin film-based filter and a fiber Bragg grating (with bandwidth 0.28 nm) inside the loop mirror that operates as the output port. A total output power of + 6.9 dBm for the two wavelengths is measured and the potential for higher output powers is discussed. Optical power and wavelength stability are measured at 0.33 dB and 0.014 nm, respectively.
XML Duplicate Detection with Improved network pruning algorithm

Duplicate Detection is critical task of any database of any organization. Duplicates are nothing but the same real time entities or objects are presented in the form of different structure and in the different formats. We can find out the duplicates in relational data, in complex data and hierarchical data like XML. There are lots of works already presented in the past for finding the duplicates in the relational data. But nowadays there is more focus on finding duplicates in the XML data. Because of XML is very popular for data storing and extensively used for data exchange between the organizations. Here we have done an extensive literature survey on this topic and proposed a duplicate detection method that incorporates some of the existing paper's ideas and some of our original ideas. In addition to improving the efficiency and effectiveness, we also checks for its typographical errors when comparing the two XML elements. To test the correctness of Improved network pruning method, we are comparing it with existing duplicate detection system, and giving more focus on how we get higher precision and recall values in the various datasets we would used.

In the title compound, C13H13N3, the cyano groups at the 2- and 5-positions are eclipsed with each other. The phenyl ring is disordered over two sets of sites, with refined occupancies of 0.520 (5) and 0.480 (5). The angles between the mean plane of the pyrrolidine ring and the two cyano groups are 71.7 (9) and 75.0 (12)°.
Evaluation of computer-based laboratory simulation models to teach scientific research strategies

The LABSIM simulation program is described, followed by a general evaluation of simulation and an indication of possible ways to improve the effectiveness of simulation models.
Using Latent Semantic Analysis to Explore Second Language Lexical Development

This study explores how Latent Semantic Analysis (LSA) can be used as a method to examine the lexical development of second language (L2) speakers. This year long longitudinal study with six English learners demonstrates that semantic similarity (using LSA) between utterances significantly increases as the L2 learners study English. The findings demonstrate that L2 learners begin to develop tighter semantic relations between utterances and words within a short period. The results have implications concerning the growth of lexical networks. This study also has important implications for inductive learning and contextualized vocabulary learning.
Cytidine 5'-diphosphocholine (CDP-choline) in stroke and other CNS disorders.

Brain phosphatidylcholine (PC) levels are regulated by a balance between synthesis and hydrolysis. Pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1 (IL-1α/β) activate phospholipase A2 (PLA2) and PC-phospholipase C (PC-PLC) to hydrolyze PC. PC hydrolysis by PLA2 releases free fatty acids including arachidonic acid, and lyso-PC, an inhibitor of CTP-phosphocholine cytidylyltransferase (CCT). Arachidonic acid metabolism by cyclooxygenases/lipoxygenases is a significant source of reactive oxygen species. CDP-choline might increase the PC levels by attenuating PLA2 stimulation and loss of CCT activity. TNF-α also stimulates proteolysis of CCT. TNF-α and IL-1β are induced in brain ischemia and may disrupt PC homeostasis by increasing its hydrolysis (increase PLA2 and PC-PLC activities) and inhibiting its synthesis (decrease CCT activity). The beneficial effects of CDP-choline may result by counteracting TNF-α and/or IL-1 mediated events, integrating cytokine biology and lipid metabolism. Re-evaluation of CDP-choline phase III stroke clinical trial data is encouraging and future trails are warranted. CDP-choline is non-xenobiotic, safe, well tolerated, and can be considered as one of the agents in multi-drug treatment of stroke.
Fatal streptococcus pneumoniae type III sepsis in mother and infant

Baby “B” was a 1,588 gram, male infant born to a 24yearold, white woman, gravida 4, para 2, who had experienced an uneventful pregnancy until spontaneous labor began at 32 weeks’ gestation. Placental membranes ruptured 10 hours prior to delivery. There was no history of maternal fever. Delivery was spontaneous and vaginal and the infant’s Apgar scores were 3 and 6 at 1 and 5 minutes, respectively. Shortly after delivery, the infant developed severe respiratory distress, cyanosis and apneic episodes and was transferred to Oklahoma Children’s Memorial Hospital. He arrived at 5 hours of age and died 1 hour after admission, in spite of intensive respiratory support and antibiotic therapy. Multiple blood cultures grew Streptococcus pnrumoniae type III. Cerebrospinal fluid culture was negative. Postmortem examination revealed extensive pneumonitis. The mother was discharged in good clinical condition on the second postpartum day. Twelve hours after discharge she developed severe headache and temperature of 40” C. She was readmitted to the hospital with signs of meningeal irritation. Examination of the cerebrospinal fluid revealed 308 white blood cells (85% polymorphonuclear leukocytes), 1,040 red blood cells, protein of 540 mgl 100 ml, and glucose of 20 mg/lOO ml. Cultures of the blood, spinal fluid, and vagina grew Streptococcus pnrumoniae type III. Soon after admission, the mother lapsed into coma and despite penicillin and intensive supportive care, she died on the fourth postpartum day.
Beam loading optimized filling patterns for partially filled storage rings

A method of selecting a favorable, with respect of the beam loading effects, multi-bunch (M bunches) filling pattern for a partially filled ring (harmonic number N) is presented. Starting with a standard set of wakefield-coupled equations of motion, the beam loading effects (higher order mode loss) are evaluated analytically (using contour integration technique) for a partially filled ring (M<N). Resulting analytic formula describe the mode loss experienced by a given bunch within a train, as a function of the resonant frequency and the quality factor of the coupling impedance, Q. The analytic formula reveals filling pattern dependent resonant frequency regions, where the beam loading effects are highly suppressed. A possible application of the presented formalism is that for a given configuration of cavity resonances one can design the optimum bunch filling pattern.
Pathway Miner: extracting gene association networks from molecular pathways for predicting the biological significance of gene expression microarray data

Summary: We have developed a web-based system (Pathway Miner) for visualizing gene expression profiles in the context of biological pathways. Pathway Miner catalogs genes based on their role in metabolic, cellular and regulatory pathways. A Fisher exact test is provided as an option to rank pathways. The genes are mapped onto pathways and gene product association networks are extracted for genes that co-occur in pathways. The networks can be filtered for analysis based on user-selected options. Availability: Pathway Miner is a freely available web accessible tool at http://www.biorag.org/pathway.html
Action potential propagation through tissue lacking gap junctions: Application to engrafted cells in myocardial infarcts

Engraftment of viable, electrically functional cells into a myocardial infarct as a method for restoring functionality is currently a topic of active research interest. Cells implanted in this way can form gap junction connectivity with each other, but often do not connect well with the surrounding tissue outside the infarct. Using a bidomain computer simulation model, we find that activation of these implanted cells by outside propagating action potentials is nevertheless possible, even if no gap junction connectivity to the surrounding tissue exists at all. The mechanism by which this action potential “tunneling” process occurs involves a current path that passes through both the intracellular and extracellular spaces, and is fundamentally spatially two-dimensional in nature. The typically convex boundary of the region occupied by these cells is found to greatly enhance the tunneling process, but unfortunately also hinders the ability of the activation of these cells to terminate reentrant waves propagating around the infarct.
Multivariate analysis of attitudes and personality characteristics among 60 youthful offenders.

Summary.-40 youthful offenders scaled 21 concepts with 12 bipolar adjectives of the semantic differential. The scaled concepts were clustered in semantic space by a multidimensional interrelational affective technique. Interpretation of the relationships of the conceprs was based on the distance function of the evaluation and potency dimensions. "Death," "black," "police," and "girl" were observed with the highest D3 function and were the most intensely stimulating affective concepts. A canonical correlational analysis was applied to the semantic factor scores of each concept and scores on the High School Personality Questionnaire. Measures of personality did not appear in the same system of relationships with any one of the 21 concepts. The realization that the punitive effects of incarceration are not, in most cases, a deterent to crime is evident in the legislation of recent years which emphasizes rehabilitation. Professional training for all levels of correctional personnel is being stressed by responsible state and federal officials. However, most of the information available on offenders tends to concentrate on their psychopathology which has the effect of isolating them as a clinical entity. There is a dearth of studies which are more positive and concern themselves with understanding the offender in terms of promoting his successful return to society (Porter, 1968). Generally the offender is unlike most populations of rehabilitation clients in that he is younger, stronger, physically healthier, and more aggressive, characteristics which are normally associated with successful rehabilitants (McGowan & Porter, 1967 ) . This study was an attempt to understand the world of the delinquent as he sees it. Otherwise, a base for meaningful communication does not exist. The two major objectives were (1) to determine if a representative sample of juvenile offenders could discriminate among 21 basic attitudes and group them into meaningful patterns and (2) to determine if any personality profile similarities were correlated with these attitudinal patterns. In most institutions for delinquent youth, retention of the individual is by civil court conviction, but the length of treatment and the termination of commitment is determined by the staff of the institution. When the delinquent's behavior has met certain ambiguous criteria that would predict probability of success "in the world," the youthful offender is released from the institution. Although voluminous data are collected on each offender and reports are lengthy, attempts to provide material for accurate decision-making about the youth, an objective measure of attitudinal change, are seldom undertaken. Rentz, White, and Fears (1968) presented some evidence that group rat
A new genus and species of brown lacewing from Venezuela (Neuroptera: Hemerobiidae), with comments on the evolution of the hemerobiid forewing radial vein

Abstract. Biramus lunatus gen.n., sp.n. is described from Venezuela. This species is of special phylogenetic interest as it is the sister-group of the subfamily Hemerobiinae (sensu Oswald, 1993), which previously contained four genera (Hemerobiella, Hemerobius, Nesobiella and Wesmaelius) and approximately 200 of the c. 550 world hemerobiid species. The conformation of the forewing radius in Biramus is especially interesting and provides a test case for distinguishing parallel evolution among forewing radial vein states within the Hemerobiidae.
Factors affecting capacitive current diversion with a uterine resectoscope: an in vitro study.

Abstract Study Objective To evaluate electrosurgical waveform, generator type, and electrode integrity as variables in capacitive induction of current on the external sheath of a resectoscope in open-circuit conditions. Design In vitro, laboratory, comparative study (Canadian Task Force classification CII-1). Setting Surgical laboratory Instrumentation Three ValleyLab radiofrequency (RF) electrosurgical generators (ESU), Force-2, Force-4, and Force-F/X; a resectoscope (Storz 50 series); and rollerball electrodes, both intact and with two types of standard insulation defects (lateral and circumferential) placed in two locations: distally, beyond the end of the telescope, and proximally, beside the distal aspect of the telescope. A Dynatek ESU analyzer was used to record current and wattage on electrodes and the external sheath. Measurements and Main Results With intact insulation, current was not disproportionately induced on the external sheath of the resectoscope regardless of ESU, power, or waveform. Proximally located electrode insulation defects allowed induction of most of the generator's output to the external sheath when high-voltage modulated outputs were used, and the risk varied somewhat with the ESU. There was no such induction at any power setting or with any insulation defect when low-voltage (cutting) outputs were tested. Conclusion In the presence of proximal electrode defects, high-voltage currents may contribute to thermal injury to the lower genital tract during RF resectoscopic surgery.
Social Goals and Basic Psychological Needs in High School Physical Education

Despite the social nature of physical education classrooms, few researchers have systematically investigated students’ social goal pursuits. Instead, investigations have typically focused on competence-related achievement goals. Grounded in Allen’s social motivation theory, the purpose of this study was to use a longitudinal framework to investigate reciprocal relationships between students’ social goals and basic psychological need satisfaction in high school physical education. A cohort of high school students (N 287) were tracked from the beginning of 9th grade to the end of 10th grade. Students reported their social affiliation goals and feelings of relatedness and social recognition goals and feelings of competence at these 2 time points. Crosssectional and longitudinal correlations supported relationships between (a) social affiliation goals and feelings of relatedness; and (b) social recognition goals and feelings of competence at these 2 time points. Intraindividual change associations between these same variables were supported by fixed effects regression models. Finally, temporal relationships were partially supported by cross-lagged path models, supporting reciprocal relationships between social recognition goals and feelings of competence. Theoretical, methodological, and practical implications of findings are highlighted.
A Serial Logarithmic Number System ALU

Serial arithmetic uses less hardware than parallel arithmetic. Serial floating point (FP) is slower than parallel FP. The Logarithmic Number System (LNS) simplifies operations, but a fast serial implementation of LNS has never been proposed previously. This paper presents a fast bit-serial LNS that combines a novel serial implementation of Mitchell's method and a new error correction method that is compatible with least-significant-bit-first serial arithmetic.
What is the Question for which Hegel's Theory of Recognition is the Answer?

The claim I propose to defend is that Hegel’s ‘theory of recognition’ is intended as an answer to a specific question in his systematic philosophy. That question is the question of the nature and the very possibility of freedom.1 This will be controversial for several reasons. First I want to treat his mature theory of ethical life or the ethical community (Sittlichkeit) (the theory published as the account of ‘objective spirit’ in the Encyclopedias and most familiarly in the lectures on the Philosophy of Right) as an extension of the original, or Jena-period theory of recognition, not its abandonment.2 A widely accepted view has it that while Hegel was originally interested in accounting for the nature and authority of social institutions by appeal to a basic inter-subjective encounter and the ‘realisation’ of such inter-subjective links, he came later to abandon that view about inter-subjectivity, and believed instead that human social and political existence was best understood and legitimated as a manifestation of a grand metaphysical process, an Absolute Subject’s manifestation of itself, or a Divine Mind’s coming to self-consciousness.3 On this interpretation, what had been a competing modern theory about the nature of human sociality, a rival to Machiavellian and Hobbsean attempts to understand how and why persons forge the links of dependence and authority that they do and must, and so a rival account of an original dependence tied to the problem of recognition, status, esteem and solidarity, not fear, power and security, became instead a conservative, organic theory, with individuals mere accidents of ‘the truly real’ ethical substance manifesting itself in time and with no central role any more to inter-subjective experience. My claim will be that this interpretation is insufficiently attentive to the unusual foundations of the mature theory of ethical life, or to Hegel’s theory of spirit (Geist), and so to the very unusual account of freedom that position justifies. Once the latter is in view, I want to show, it is much easier to see how the ‘ethical life theory’ is an account of successful recognition, or a mutuality based on a kind of rational acknowledgement. Secondly the claim is controversial because defending that proposition will involve the claim that the theory of recognition is not primarily to be understood (as it often is in post-war Hegel scholarship) as a comprehensive transcendental theory about self-awareness, as if about the possibility of any self-relation (as if the contents of any such self-relation are and must be internalisations of ways of being-regarded by others), is not primarily a genetic theory about the formation
A dual-time-scale finite element model for simulating cyclic deformation of polycrystalline alloys

A dual-time-scale finite element model is developed in this paper for simulating cyclic deformation in polycrystalline alloys. The material is characterized by crystal plasticity constitutive relations. The finite element formulation of the initial boundary-value problems with cyclic loading involves decoupling the governing equations into two sets of problems corresponding to two different time-scales. One is a long-time-scale (low-frequency) problem characterizing a cycle-averaged solution, while the other is a short-time-scale (high-frequency) problem for a remaining oscillatory portion. Cyclic averaging together with asymptotic expansion of the variables in the time domain forms the basis of the multitime-scaling. The crystal plasticity equations at the two scales are used to study cyclic deformation of a titanium alloy Ti-6Al. This model is intended to study the fatigue response of a material by simulating a large number of cycles to initiation.
Lipid-apolipoprotein interactions in surfactant studied by reassembly.

Recent evidence suggests that the structure of tubular myelin, an extracellular form of pulmonary surfactant, is dependent on the interaction of lipids with certain proteins specific for this material and with calcium ions. In order to investigate how protein and calcium may affect the surfactant complex, we studied the composition and properties of reassembly materials formed with a major surfactant apolipoprotein (35,000-38,000 molecular weight) and the principal lipids found in the natural material. We were interested in three questions: 1) Does this apolipoprotein preferentially associate with certain of the lipids in surfactant? 2) What forces are involved in the binding? 3) Does the interaction result in changes in the physical state of the lipid?We found that this apolipoprotein binds phosphatidylcholines that are in a gel phase with much greater affinity than it does phosphatidylcholines that are liquid-crystalline. However, maximum binding does not occur with the pure phosphatidylcholines but rat...
Constructing stable grasps in 3D

This paper presents fast and simple algorithms for directly constructing stable grasps in 3D. The synthesis of stable grasps constructs virtual springs at the contacts, such that the grasped object is stable, and has a desired stiffness matrix about its stable equilibrium. The paper develops a simple geometric relation between the stiffness of the grasp and the spatial configuration of the virtual springs at the contacts. The stiffness of the grasp also depends on whether the points of contact stick, or slide without friction on the edges of the object.
COMPARISON OF FREQUENCY DETERIIINATION TECHNIQUES FOR CANTILEVERED PLATES WITH BENCING-TORSION COUPLING

Various techniques for solution of the variational statement governing vibration of cantilevered composite plates are compared. The partial Ritz method assumes mode shapes only in the chordwise direction and reduces the problem to a set of ordinary differential equations. The important nondimensional p arameters for cantilevered plates with bending-torsion coupling are then easily identified, including two which express the relative contribution of the warping stiffness to torsional vibration (BG6) and chordwise vibration (a,,). The Rayleigh-Ritz solution, requiring assumed mode shapes in both directions, reveals the fundamental coupling mechanisms affecting the natural mode shapes and frequencies. The finite element method yields direct accurate results, yet masks the fundamental behavior. Experiments w ere performed to provide data for correlation with the analyses. The various solution techniques p rovide different levels of insight into the fundamental vibration characteristics of cantilevered plates with bendiqgtorsion couplin-, including the importance of chordwise flexure in the torsional vibration modes.

HIV-related oral disease

Summary Few people with HIV infection fail to experience oral lesions during the course of their disease. Oral mucosal and salivary gland manifestations include several that were not seen before the AIDS epidemic, while others are more severe in this population. Oral lesions reflect HIV status and the stage of immunosuppression, are important elements in HIV staging and classification schemes, raise pertinent questions about mucosal aspects of immunosuppression, and provide therapeutic challenges. Their pervasive nature and biological significance emphasise the importance of a careful oral examination as part of the general clinical evaluation.
Photocatalytic degradation of organic water contaminants: Mechanisms involving hydroxyl radical attack

Abstract Hydroxyl and other oxygen-containing radicals are known to be present during the degradation of organic water pollutants in illuminated TiO2 photocatalyst slurries. It is proposed that the hydroxyl radical, OH·, is the primary oxidant in the photocatalytic system. Four possible mechanisms are suggested, all based on OH· attack of the organic reactant. The cases of reaction on the surface, in the fluid, and via a Rideal mechanism are shown to yield expressions similar to Langmuir-Hinshelwood (LH) rate forms. Compared with traditional LH constants, the derived kinetic parameters represent fundamentally different reactions and properties. A rate parameter independent of organic reactant is predicted by the model and substantiated by experimental degradation data. On the basis of these model results, the kinetic parameters for the photocatalytic degradation may be estimated from data on the photocatalyst's physical properties, the knowledge of electron-hole recombination and trapping rates, and the values of second-order reaction rate constants for hydroxyl radicals.
The Effects of a Multilingual Telephone Quitline for Asian Smokers: A Randomized Controlled Trial

Methods A culturally tailored counseling protocol was developed in English and translated into Chinese, Korean, and Vietnamese. We conducted a single randomized trial embedded in the California quitline service. Smokers who called the quitline’s Chinese, Korean, and Vietnamese telephone lines between August 2, 2004, and April 4, 2008, were recruited to the trial. Subjects (N = 2277) were stratified by language and randomly assigned to telephone counseling (self-help materials and up to six counseling sessions; n = 1124 subjects) or self-help (self-help materials only; n = 1153 subjects) groups: 729 Chinese subjects (counseling = 359, self-help = 370), 848 Korean subjects (counseling = 422, self-help = 426), and 700 Vietnamese subjects (counseling = 343, self-help = 357). The primary outcome was 6-month prolonged abstinence. Intention-to-treat analysis was used to estimate prolonged abstinence rates for all subjects and for each language group. All statistical tests were two-sided. Results In the intention-to-treat analysis, counseling increased the 6-month prolonged abstinence rate among all smokers compared with self-help (counseling vs self-help, 16.4% vs 8.0%, difference = 8.4%, 95% confidence interval [CI] = 5.7% to 11.1%, P < .001). Counseling also increased the 6-month prolonged abstinence rate for each language group compared with self-help (counseling vs self-help, Chinese, 14.8% vs 6.0%, difference = 8.8%, 95% CI = 4.4% to 13.2%, P < .001; Korean, 14.9% vs 5.2%, difference = 9.7%, 95% CI = 5.8% to 13.8%, P < .001; Vietnamese, 19.8% vs 13.5%, difference = 6.3%, 95% CI = 0.9% to 11.9%, P = .023). Conclusions Telephone counseling was effective for Chinese-, Korean-, and Vietnamese-speaking smokers. This protocol should be incorporated into existing quitlines, with possible extension to other Asian languages.
Intraurethral activation of excitatory bladder reflexes in persons with spinal cord injury

Electrical activation of an excitatory reflex between sensory fibers in the pudendal nerve and the bladder has been demonstrated in cats and is a potential means of restoring micturition function in persons with spinal cord injury. We investigated the clinical feasibility of activating this reflex to restore bladder function in persons with spinal cord injury by using intraurethral electrical stimulation to activate pudendal sensory fibers innervating the urethra. Excitatory bladder responses (contractions) were evoked by trains of electrical pulses applied to either the proximal (29.7 ± 11.6 cmH 2 O) or distal (30.2 ± 11.6 cmH 2 O) segment of the urethra. The results indicate that an excitatory reflex between pudendal nerve afferents and the bladder exists in humans with spinal injury and may provide a substrate for restoring micturition function.
The K-admissibility of SL(2, 5)

Let K be a field and let G be a finite group. G is K-admissible if there exists a Galois extension L of K with G=Gal(L/K) such that L is a maximal subfield of a central K-division algebra. We characterize those number fields K such that H is K-admissible where H is any subgroup of SL(2, 5) which contains a S2-group. The method also yields refinements and alternate proofs of some known results including the fact that A5 is K-admissible for every number field K.
The Behavior of Winter Stationary Planetary Waves Forced by Topography and Diabatic Heating

Abstract A primitive equation linear wave model is developed to examine the effects of mean zonal wind structure on the vertical propagation of stationary planetary waves and to identify the characteristics of the winter stationary waves forced by realistic topography and diabatic heating. An analytic mean zonal wind model is used to facilitate changing the wind structure parameters for comparative experiments. A more realistic mean wind profile is used to simulate the observed behavior of stationary waves more closely. The experiments confirm the sensitivity of vertical wave propagation to the mean wind structure, especially to the latitudinal curvature of the mean wind. The role of the polar night jet in channeling the planetary waves as they propagate vertically is emphasized. At is found that the latitudinal location of the polar night jet also has a significant influence upon the wave propagation. A mechanism is proposed to explain the possible connections between the change in the location of the po...
Automated Jurisprudence in a Quasi-Judicial Setting

Today, we live in an age where human decision-makers interpreting how law applies to cases are being replaced or supplemented by automata. Given this, we are forced to ask a number of questions. These are largely old questions, but the current trend towards automation puts them in a new light. What is the proper role of the judge; is she a wise decisionmaker or blind follower of rules? To what extent must the judge be empathetic and truly aware of the facts of the case in order for our notion of due process to be satisfied? Can a machine properly interpret statutes and how they apply in an individual case? And does the machine fit into the preconceptions of a legal actor held by both bureaucrats and citizens? How if at all should these preconceptions change? In this paper, an attempt will be made to address these questions and provide suggestions that will allow for the automation of law to uphold the rule of law.
Dying well: How equal is end of life care among gynecologic oncology patients?

Abstract Objective To identify disparities in utilization of end of life (EoL) resources by gynecologic oncology (GO) patients. Methods This retrospective analysis of the medical records of GO patients treated 1/2007–12/2011 and deceased 1/2012–8/2014 evaluated patient demographics, disease characteristics, and utilization of EoL resources. Chi-square, Fisher's exact test, Mann Whitney and Kruskal–Wallis tests were used for statistical analysis. Results Of 189 patients analyzed, 113 (60%) were white, 38 (20%) Hispanic, 31 (16%) black, and seven (4%) Asian. Ninety-five (48%) had ovarian cancer, 51 (26%) uterine, 47 (23%) cervical, seven (3%) vulvar/vaginal. In the last 30days of life (DoL), 18 (10%) had multiple hospital admissions, 10 (5%) admitted to the Intensive Care Unit (ICU), 30 (16%) multiple Emergency Room (ER) visits, 45 (24%) received aggressive medical care and eight (4%) received chemotherapy in the final 14 DoL. Furthermore, 54 (29%) had no Supportive Care referral and 29 (15%) no hospice referral. Only 46 (24%) had a Medical Power of Attorney (PoA) or Living Will (LW) on file. Non-white race was associated with increased odds of dying without hospice (OR 3.07; 95%CI [1.27, 2.46], p=0.013). However, non-white patients who enrolled in hospice did so earlier than white patients (42 v. 27days before death, p=0.054). Non-white patients were also significantly less likely to have PoA/LW documentation (24% v. 76%, p=0.009) even if enrolled in hospice (12% v. 31%, p=0.007). Conclusions Significant racial disparities in hospice enrollment and PoA/LW documentation were seen in GO patients. This warrants further study to identify barriers to use of EoL resources.
Diel Feeding Ecology of Slimy Sculpin in a Tributary to Skaneateles Lake, New York

Abstract Interactions among the benthic community are typically overlooked but play an important role in fish community dynamics. We examined the diel feeding ecology of Slimy Sculpin (Cottus cognatus) from Grout Brook, a tributary to Skaneateles Lake. Of the six time periods examined, Slimy Sculpin consumed the least during the nighttime (2400 h and 0400 h). Chironomids were the major prey consumed during all time periods except for 2400 h when ephemeropterans were the major prey consumed. There was a moderate preference by Slimy Sculpin for food from the benthos (0.59 ± 0.06) with Diptera (Chironomids), Ephemeroptera (Baetidae), and Trichoptera (Brachycentridae) representing the major taxa. Slimy Sculpin appear to be opportunistic feeders selecting what is most available in the brook. Index of fullness was variable and averaged 1.15% across the diel cycle. Daily ration was measured as a function of fish dry body weight and ranged from 0.12 to 0.22. Estimates of daily consumption ranged from 0.007% to 4....
Mobile Broadband Infrastructure and the Spectrum Crunch: A Techno-Economic Analysis

The business news media in the US and many other countries has been publishing numerous stories on the looming spectrum scarcity. There have also been numerous reports of mobile operators around the world are opportunistically acquiring spectrum and lobbying their national regulatory authorities for more allocations. The rationale for these demands for new spectrum is the tremendous growth in mobile data traffic that has occurred with the proliferation of smartphones, tablets, and other mobile devices with internet access, notwithstanding the new applications, such as sensors, that are creating new demands as well. The reality is that wireless capacity results from a production function that has spectrum, architecture and transmission technology as inputs. This production function is quite complex, making it difficult for policymakers to respond appropriately to requests from carriers for more spectrum allocations. In this paper, we will create a model that will serve to assist regulators in assessing the marginal benefit of allocating additional spectrum for mobile broadband usage relative to other inputs, such as new cell‐sites and more efficient transmission technologies. This preliminary model will be based on both technical and economic parameters. In this paper, we will narrow the problem space by considering only one frequency band and one technology, preferably LTE-Advanced though that will depend on the capabilities of the modelling tools still being evaluated. We believe this research has significant long term benefits for regulators, as they will be able to make better allocative judgments for radio spectrum around a technology that will be relevant for the next ten years or so. Given that new spectrum has historically taken between six and thirteen years to make available (according to the FCC), and since mobile data growth trends are likely to continue beyond the near‐term forecast, we do not expect to see demands for new spectrum from operators ebbing. At the same time, because spectrum is only one of the inputs to mobile systems, regulators must be in a better position to evaluate the claims by carriers so they can make superior spectrum allocation decisions. We believe that a tool like the one being proposed will help regulators and carriers produce Pareto-superior social welfare compared with allocative decisions that are not informed by such a tool.
Advanced device performance impact by wafer level 3D stacked architecture

A high density 50K∼100K/mm2 cross-tier connection featuring backside through-via (BTV) and wafer level 3D stacking technologies has been successfully demonstrated. Wafer stacking and thinning to < 1/250 Si thickness process showed little to no impact to advanced device performance. BTV induced stress effect was also studied; quite different behaviors between wafers with SiGe and without SiGe process were found. SiGe local strain will be diminished by BTV induced strain when BTV getting too close to channel, and hence lower hole mobility. This impact could be minimized by proper Keep-Out Zone (KOZ) design. Furthermore, 3D stacked architecture provides the opportunity to individually optimize process and design for each function block on separated wafers, thus improve chip performance and power consumption, and also benefit chip footprint.
Additive Manufacturing of 17-4 PH Stainless Steel: Post-processing Heat Treatment to Achieve Uniform Reproducible Microstructure

17-4 precipitation hardenable (PH) stainless steel is a useful material when a combination of high strength and good corrosion resistance up to about 315°C is required. In the wrought form, this steel has a fully martensitic structure that can be strengthened by precipitation of fine Cu-rich face-centered cubic phase upon aging. When fabricated via additive manufacturing (AM), specifically laser powder-bed fusion, 17-4 PH steel exhibits a dendritic structure containing a substantial fraction of nearly 50% of retained austenite along with body centered cubic/martensite and fine niobium carbides preferentially aligned along interdendritic boundaries. The effect of post-build thermal processing on the material microstructure is studied in comparison to that of conventionally produced wrought 17-4 PH with the intention of creating a more uniform, fully martensitic microstructure. The recommended stress relief heat treatment currently employed in industry for post-processing of AM 17-4 PH steel is found to have little effect on the as-built dendritic microstructure. It is found that, by implementing the recommended homogenization heat treatment regimen of Aerospace Materials Specification 5355 for CB7Cu-1, a casting alloy analog to 17-4 PH, the dendritic solidification structure is eliminated, resulting in a microstructure containing about 90% martensite with 10% retained austenite.
