Reinventing public health education for the 21st century.

In this article the authors discuss the reinvention of U.S. public health education for the 21st century. They argue that the role of public health in creating population health and improving public health education must be better defined, cite several reports by public health organizations calling for a reexamination of public health education, such as the Lancet Commission, and discuss the challenges of reenvisioning public health education.
Precision heat capacity measurements for the characterization of two-phase polymers

Structure sensitive thermal analysis results on linear macromolecules can be obtained when correcting measurements with heat capacity instead of “baseline” data. The ATHAS (Advanced Thermal Analysis) effort in heat capacities of crystals, glasses and liquids is described, and applied to the interpretation of microphase separated samples. Semicrystalline homopolymers, block-copolymers, and blends are to be discussed.
Low-threshold quantum well lasers grown by metalorganic chemical vapor deposition on nonplanar substrates

Low-threshold quantum-well lasers having as-grown optical and electronic confinement fabricated by a single-step growth on nonplanar substrates are discussed. Several devices using various approaches for delineating narrow active regions by this technique are described. Fully planar index-guided arrays grown over a nonplanar substrate exhibit a threshold current of 8 mA per element. A technology called temperature engineered growth, which permits the formation of submicrometer active-region widths and wide contacting regions in the same growth step, is introduced. Lasers having active regions as narrow as 0.5 mu m grown using this technology display stable single-transverse-mode operation. CW threshold currents as low as 2.5 mA at room temperature with differential quantum efficiencies of 34%/facet were measured for uncoated devices. >
Comparison of the Immunogenicity of Intramuscular Versus Subcutaneous Administration of Trivalent Inactivated Influenza Vaccine in Individuals With Neuromuscular Diseases

Individuals with neuromuscular disease show a wide spectrum of muscle pathology. To test the hypothesis that the immune response to trivalent inactivated influenza vaccine is potentially inadequate when given intramuscularly into a fibrosed muscle, this prospective randomized study compared the immunogenicity and safety of the standard intramuscular versus subcutaneous administration of the influenza vaccine in 22 nonambulatory subjects, of whom 10 have been on glucocorticoid therapy. Analysis of hemagglutination inhibition antibody titers showed high prevalence of seroprotection (prevaccination of 82% H1N1, 72% H3N2, 31% B; postvaccination of 100% H1N1, 77% H3N2, 59% B). Geometric mean titer ratios for each antigen showed no significant difference (P > .5) between intramuscular and subcutaneous routes. Seroprotection was not adversely affected by glucocorticoid therapy. Local tolerance was better with subcutaneous route. Larger studies are needed to confirm these preliminary results.
The pattern of Wallerian degeneration in the optic nerve of newborn kittens: An ultrastructural study

Summary Following eye enucleation, Wallerian degeneration was studied in optic nerves of newborn kittens, whose age varied from 1 to 14 days at the time of operation. The survival time ranged from 1 to 28 days post-enucleation. The nerves were examined at a distance of 5 mm from the site of transection. Axons yet to be myelinated (non-myelinated) underwent a complete disruption with very little evidence of debris. Most myelinated axons underwent a flocculation and condensation of the axoplasm which resulted in a ‘dark’ pattern of degeneration. In other myelinated axons there was no evidence of axonal debris and this type of degeneration was termed ‘watery’. The latter type of degeneration appeared to be limited to the larger axons. Although almost all axons had degenerated by 4 days post-enucleation, only the ‘dark’ type persisted for any length of time. The ‘dark’ pattern was only seen in axons surrounded by several myelin lamellae. Evidence of phagocytosis of myelin was seen 4 days post-enucleation and was performed by oligodendroglia. At 28 days post-operation, very little debris remained and the optic nerve consisted almost entirely of astrocytic scar tissue, among which were scattered oligodendroglia cells that contained many lipid inclusions. These observations are compared with those seen in the adult animal. The rate of axonal degeneration and the subsequent removal of debris is faster in the kitten than that seen in the optic nerve of mature animals and it is suggested that this may be due to the greater metabolic activity of immature tissue.
An International Discussion about Cross-Cultural Career Assessment.

Career assessments are a common resource used by career practitioners internationally to help inform individuals’ career decision-making. Research on the topic of cross-cultural career assessment has been mostly limited to the applicability of an established inventory to a different culture. The purpose of this paper is to summarize the existing research on cross-cultural assessment, and to indicate a need for collaboration among career development associations with respect to the value and use of career assessments, using current ethical standards as a springboard for determining common ground and perhaps a joint statement about the value of career assessments.
Haemolysis, elevated liver enzymes and low platelets syndrome: Ultrasound and magnetic resonance imaging findings in the liver

SUMMARY We describe the imaging findings of the HELLP (haemolysis, elevated liver enzymes and low platelets) syndrome in a gravid 36-year-old-woman who presented at 19.5 weeks gestation with severe right upper quadrant pain. Ultrasound findings suggested a focal hyperechoic liver lesion suggesting pregnancy-related hepatopathy prior to development of biochemical signs of HELLP syndrome. Within 3 days, the patient developed characteristic clinical and laboratory evidence of the HELLP syndrome. MR imaging at this time demonstrated localized hepatic ischaemia, further strengthening the diagnosis of HELLP syndrome.
Absence of slow channel-dependent conduction within the His-Purkinje (bundle branch) reentrant circuit: A clinical and experimental study of the effects of verapamil

Abstract The effects of intravenous verapamil on intraventricular conduction and reentry within the His-Purkinje system were studied in 10 patients and 8 dogs using His bundle electrograms and the ventricular extrastimulus method. In the clinical study, ventricular stimulation was performed by applying stimuli of two times diastolic threshold current strength and in the dog study by applying stimuli ranging in strength from two times diastolic threshold strength to 40 mA. In the clinical study, verapamil was given intravenously as a bolus injection (0.075 to 0.15 mg/kg body weight) and in the dog study as a rapid infusion (0.7 to 1 mg/kg) over 10 minutes followed by continuous infusion at a rate of 0.014 mg/kg per min. Plasma verapamil concentrations ranged from 91 to 173 ng/ml (mean ± standard deviation 138 ± 27) in the clinical study and from 103 to 638 ng/ml (mean 459 ± 174) in the dog study. In both studies, verapamil produced no change in latency and intramyocardial (duration of QRS complex) and His-Purkinje (V 2 -H 2 interval) conduction of even the earliest premature impulses delivered before the repolarization of the His-Purkinje system or ventricular muscle, or both, was completed; that is, some fibers might have been at the level of membrane potential at which conduction becomes wholly or in part dependent on the current flowing through the slow channel. Verapamil did not change significantly the determinants of reentry and did not abolish or modify the zone of reentry in any of the 10 patients. These results show that in patients with normal intraventricular conduction, slow channel-dependent conduction plays no role in the propagation of even the earliest premature impulses through the His-Purkinje reentrant circuit. In the absence of any evidence of slow channel-de-pendent conduction, one must assume that the slow propagation of very early premature impulses was mediated by incompletely reactivated rapid inward current system. These observations suggest that the system responsible for slow conduction cannot be recognized from the magnitude of conduction delay.
Embracing human fallibilty: On forgiving oneself and forgiving others

Forgiving another and forgiving oneself are both experiences that bring relief and a sense of a new beginning in life. The relationship between these two phenomena is explored through a phenomenological and hermeneutical interpretation of one person's story of reconciliation. It is argued that guilt and shame give rise to the search for forgiveness, and that in either type of forgiveness one moves into a deeper and more profound connection with one's own life as well as the lives of others.
Negotiating Assimilation: Chicago Catholic High Schools' Pursuit of Accreditation in the Early Twentieth Century

At the Catholic Educational Association's (CEA) annual meeting in 1911, Reverend John E Green, president of St. Rita College Prep, an academy for boys on the southwest side of Chicago administered by the Augustinian Fathers, argued against Catholic schools' seeking accreditation from non-Catholic institutions. He called the practice “a heterodoxical spectacle” and “a stultification of our claim of the necessity of Catholic education.” Reverend Green opposed accreditation by both state agencies and professional associations, but just five years later requested assistance from the speaker of the Illinois House of Representatives, David E. Shanahan, to pursue state recognition for St. Rita. Speaker Shanahan called on the Illinois Superintendent of Public Instruction and asked him to respond to Reverend Green's request to dispatch the Illinois High School Supervisor to St Rita. What motivated a staunch opponent of recognition and accreditation like Green to go to such lengths to procure it? While accreditation by non-Catholic institutions did not negate the need for Catholic education, as Reverend Green feared, how did it contribute to the assimilation of Catholic schools and hence Chicago Catholics in the early twentieth century?
Sparse recovery for Earth Mover Distance

We initiate the study of sparse recovery problems under the Earth-Mover Distance (EMD). Specifically, we design a distribution over m × n matrices A, for m « n, such that for any x, given Ax, we can recover a k-sparse approximation to x under the EMD distance. We also provide an empirical evaluation of the method that show, in some scenarios, its advantages over the “usual” recovery in the l p norms.
Reduced peak-hopping artifacts in ultrasonic strain estimation using the Viterbi algorithm

Internal strain resulting from tissue deformation can be estimated by correlation processing of speckle patterns within complex (i.e., radio frequency) ultrasound images acquired during deformation. At large deformations, the magnitude of the correlation coefficient peak can be significantly lower than unity, so that random speckle correlations will exceed the true peak. This effect is called "peak hopping" and causes significant errors in displacement and deformation estimates. Here we investigate the Viterbi algorithm, a dynamic programming procedure, to overcome peak-hopping artifacts by finding the most likely sequence of hidden states in a sequence of observed events. It is well suited to motion estimation in elasticity- imaging studies because adjacent tissue elements remain adjacent following deformation. Particularly, tissue elements along an ultrasonic beam in one image lie along a 3-D continuous curve in the next image instant. The observed event in this case is the correlation coefficient of a pixel at a certain displacement. Radio-frequency data were generated before and after deformation with an average strain of 6%. Simulations were performed for a homogenous medium and for a medium with a stiffer inclusion. Results show that Viterbi processing of speckle-tracking outputs can significantly reduce peak-hopping artifacts.

Beneficial actuator-induced bifurcations in compressor control

There has been a concerted effort to use feedback to either stabilize or ameliorate the detrimental effects of the aerodynamic instabilities of rotating stall and surge in compression systems of jet aircraft engines. Typical model-based efforts have largely focused on eliminating a treacherous hysteresis loop in the Moore-Greitzer equations, making stall recovery possible without resorting to drastic measures. The present note is motivated by peculiar and very interesting observations of the behavior of certain control laws when the performance of the actuator deteriorates (increased time lag between the commanded and actual control input). The degradation induces an instability which surprisingly improves the performance of the controller. In the following sections, we briefly describe the phenomenon and then offer an explanation by unfolding a doubly-degenerate bifurcation.
Masculinized sexual partner preference in female zebra finches with sex-reversed gonads.

Previous research in the zebra finch, a socially monogamous pair-bonding species, suggests that the preference for opposite-sex partners may arise in part through the organizing actions of sex steroids. To further investigate this process, zebra finch eggs were injected with 20 μg fadrozole, a potent estrogen synthesis inhibitor, or with the saline vehicle on embryonic day 5. As adults they were given two-choice sexual partner preference tests followed by group aviary tests. Fadrozole females had masculinized beak color and had testes or ovotestes instead of ovaries. Males were not affected by fadrozole; they did not differ from controls on any measure. In contrast, sexual partner preference was substantially masculinized in fadrozole females in the group aviary tests. Untreated males given a choice between fadrozole and untreated females preferred the untreated females, but this was equally the case when they were given a choice between saline-treated and untreated females. These results suggest that males do not specifically avoid females with testes and that male avoidance is unlikely to explain why fadrozole-treated females pair with other females. The present data add to the evidence that actions of gonadal steroids during development contribute to adult sex differences in partner preference in this pair-bonding species. Furthermore, because fadrozole-treated females do not produce audible song, the mechanisms regulating partner preference and song system development are dissociated.
Blind equalization of time-varying channels: a deterministic multichannel approach

Blind equalization of rapidly changing multipath channels is important for mobile communications, and is addressed by expanding the time-varying channel over a basis. Time-variation offers diversity and in contrast to time-invariant channels, blind equalization of time-varying channels becomes possible under mild conditions provided that the expansion components can be separated. Multichannel data are needed for the challenging non-separable case where it is shown that unique vector FIR equalizers exist under certain channel co-primeness conditions. Apart from persistence of excitation, no extra restriction is imposed on the input. Order selection methods and blind equalizers are derived directly from the output data. Preliminary simulations are also presented.
Determining person–organization fit for healthcare CEOs: How executive equity sensitivity relates to nonprofit and for-profit sector selection

This article empirically examines the relationship between the trait of equity sensitivity and employment sector (for-profit, public, and nonprofit) for senior executives. By controlling for industry (healthcare), we show a relationship between this trait and employment sector in both a single-state survey and a multistate survey. Findings indicate that benevolents have a propensity to pursue nonprofit positions whereas entitleds are likely to gravitate toward for-profit positions. Implications for job seekers, employers, and academics are provided.
A ''Call to Action'' for an Expanded Pharmacist Role in Influencing the Quality of Nutrition Care

They have made it clear that malnutrition has a significant negative impact on patient outcomes and have identified that malnutrition in hospitals is both poorly recognized and treated. Their “Call to Action” is well founded and should be fully supported. However, it is not entirely interdisciplinary by the criteria of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.).
Table-driven rules in expert systems

The structure and organization of expert systems can be usefully modeled after corresponding human experts. Often this modeling degrades because of insufficient expressive power in production system languages. Relational table techniques provide additional abstraction capabilities and are useful in extending the expressiveness of production system rules; the resulting systems can be easier to build, understand and debug because they can reflect more accurately human methods of reasoning. The number of superfluous rules is reduced by organizing much of the problem domain knowledge in relations in working memory. The relational table methods also provide a tool for the interfacing of knowledge bases and databases.
Regional density functions and growth patterns in major plains of China, 1982–1990

This research analyzes the spatial patterns of regional development in China through the change of population density functions from 1982 to 1990, using several online digital data sets. To minimize the influence of physical environment on population densities, the study areas are limited to four major plains of China: the Northeast (Dongbei), North China (Huabei) and Hubei-Hunan (Lianghu) Plains, and the Sichuan Basin. A gravity-based delineation approach is used to delineate the influen ce regions of 17 cities. Regional densities in China decline with distance from a city, similar to western countries. In addition, areas close to central cities grew faster than remote areas, described as a trend of centralization. However, regions with strong core growth are generally associated with stagnant hinterlands (‘core growth-hinterland stagnation’); and regions with moderate core growth are usually matched by similar growth rates in the hinterlands (‘spread through growth’ ).
Analysis of the flow of encapsulant during underfill encapsulation of flip-chips

In this paper, the flow of encapsulant during the underfill encapsulation of flip-chips has been studied. Analytical as well as numerical methods have been developed to analyze the flow. For capillary-driven encapsulation (by dispensing), the capillary force at the melt-front has been calculated based on a model for the melt-front shape. A model has also been developed for the analysis of forced-injection encapsulation. The numerical analysis uses a finite-element method based on a generalized Hele-Shaw method for solving the flow field. Experiments have been performed to investigate the flow behavior using actual chips and encapsulants. Short-shot runs have been performed to observe the melt-front advancement at different flow times. In addition, measurements have been made of the material properties of the encapsulant, namely its viscosity, curing kinetics and surface-tension coefficient. The experimental and simulation results have been compared in terms of the flow-front shapes and times at different fill fractions. Such comparisons indicate that the model developed in this study is adequate to approximately simulate the flow during encapsulation of flip chips.
Rhetorical Invention in Design Constructing a System and Spec

Though scholars have begun to explore how texts mediate design, little is known about rhetorical invention in design. To investigate how heuristics used for rhetorical invention and design might be related, the author analyzed how one disciplinary design heuristic, the information system cliche, influenced the production of both a computer system and a specification text for the system. The cliche was used to generate design proposals, which designers evaluated using at least three criteria: projected context of use, correspondence between the proposals and their textual inscriptions, and system coherence. Results indicate that disciplinary heuristics and rhetorical topics overlap in design; however, the rhetorical character of disciplinary heuristics is obscured in textual representations of the design. Both types of heuristic serve as interpretive instruments and are used dialogically to develop the parts of a design or text within the context of the whole.

Acarbose for Polycystic Ovary Syndrome

Objective:To review the evidence for use of acarbose in the management of polycystic ovary syndrome (PCOS).Data Sources:Relevant publications were identified through a systematic search of PubMed English-language literature (1950–February 2008) using the MeSH terms and key words acarbose and polycystic ovary syndrome.Study Selection and Data Extraction:The literature search retrieved 6 primary literature citations. Three randomized controlled clinical trials and one open-label study were evaluated. The other 2 citations were not evaluated due to only a peripheral mention of PCOS in relation to diabetes.Data Synthesis:PCOS is a complex disorder presenting most commonly with oligomenorrhea or amenorrhea, infertility, hirsutism, acne, and obesity. Acarbose is a promising therapy for PCOS because of its effects on postprandial insulin levels. In multiple clinical studies, acarbose improved hirsutism, acne, and menstrual irregularities through reduction in androgen concentrations and through increased androgen...
Low-Cost Earth Imaging System for Novel Commercial Applications

Observations of the Earth from space have traditionally been dominated by applications that require very accurate pointing to specific locations of interest, with high reliability and small latency. Today the general public has access to high-resolution imagery on a scale never before imagined, and demand for this resource is increasing. Acquiring large data sets of Earth imagery in a simple, low-cost way represents a new market opportunity that has yet to be answered. Without the restrictions of the traditional imaging model, there exists a new design paradigm that presents new options and new challenges to be investigated. It is the purpose of this paper to discuss a system design for a low-cost satellite and ground system that addresses the challenges of this new paradigm. The paper will include an analysis of orbit-specific coverage metrics for such a system, as well as a summary of the system-level trades and resulting point design.

Crime and Punishment among the Teutonic Knights

Was there crime among the brethren of the Order of the Teutonic Knights, who in addition to taking vows of poverty, chastity, and obedience were commanded to "behave towards each other so that friendly concord in the name of brotherhood does not turn into hardness of heart, and to take pains to live with each other in brotherly love, harmoniously and amicably, in the spirit of gentleness"?' And if wrongdoing existed, was there also punishment for those who had sinned or committed an offense? The statutes of the order provide an answer to this question: "Since . . . even lay folk must give account at the Day of Judgment for every idle word, so it is much more incumbent upon professed brethren that they atone for their sins . . . and that the order be purgatory for them,"2 for the "aim of all life in religion shall be that the order endure and that sins be punished."3 The founders of the Order of the Teutonic Knights the German ecclesiastical and temporal princes in Palestine meeting in the house of the Templars in Jerusalem in 1195 or 1198, decided that the German hospital, which eventually evolved as the Order of the Teutonic Knights, should be modeled after the Hospital of St. John of Jerusalem in its program for the poor and sick; but in clerical, knightly, and other activities, after the Knights Templars. This decision was approved by Pope Innocent III on February 19, 1199.4
Parallel programmable finite field GF (2/sup m/) multipliers

Block (cyclic) channel coding standards for third generation cellular networks require the implementation of high-performance burst-error detection and correction algorithms. Galois field (GF) arithmetic is commonly used in this architecture for encoding and decoding error codes, however, many architectures still do not support dedicated functional units. This paper presents the design of a generic parallel finite-field GF (2/sup m/) multiplier targeted at DSP and embedded processors. As opposed to previous research, this design has the ability to utilize different primitive polynomials as an input, thereby, being able to be programmable. Moreover, a design is presented that is a combined binary and finite-field GF (2/sup m/) multiplier. Area, delay, and power dissipation results are presented from several ASIC libraries.
Potential Unintended Consequences of a Conservative Management Strategy for Patent Ductus Arteriosus.

Background A recent review supports a strategy of deferring treatment of patent ductus arteriosus (PDA) in the preterm neonate until at least the second week after birth. In light of previous suggestion that later initiation of treatment may be less efficacious for closing PDAs it is reasonable to question if delayed treatment may be less effective. Design We conducted a single center retrospective review of a neonatal intensive care unit database of infants ≤37 weeks gestation with the diagnosis of PDA and treated with indomethacin from 1999 to 2007. We determined gestational age (GA), timing of indomethacin initiation, and status of the PDA at hospital discharge. Treatment failure was defined as neonates requiring further intervention to close their PDA or those who died without echo-proven PDA closure. Results Of the 341 infants meeting the study criteria, 77 (23%) had defined treatment failure. The failure group had a younger median GA of 25 weeks (interquartile range [IQR], 24–26) vs. 28 weeks (IQR, 26–30) for the successful group (P < .0001). The failure group had a median treatment initiation on day of life (DOL) 4 (IQR, 1–8) compared with DOL 3 (IQR, 1–6) for those in the successful group (P = .15). Taken as a whole, infants treated after DOL 5 were significantly more likely to have treatment failure (30.1% vs. 19.3% for those treated DOL 1–5, P = .03). Conclusions Our study confirms that younger GA at birth is correlated with increased likelihood of failed PDA closure. We also show a trend indicating that later initiation of treatment may decrease the chances of successfully closing a PDA. Future examination of PDA management should consider the potential unintended consequences that may accompany a delayed treatment strategy.
A New Look at the Israeli Cloud Seeding Experiments

Abstract Two statistical experiments, carried out in Israel, appeared for a time to have provided a unique demonstration of the ability of cloud seeding to increase rainfall. In this paper the authors examine the possibility that both experiments were compromised by type I statistical errors (i.e., “lucky draws” or false positives). It is concluded that in the first Israeli experiment a type I statistical error produced the appearance of statistically significant effects of artificial seeding on rainfall 1) in the buffer zone and the center target area, 2) in the coastal region of Israel, a few kilometers downwind of the seeding, and 3) in portions of Lebanon, Syria, and Jordan. Analysis of the second Israeli experiment using the original crossover design produced a null result. However, when the two target areas were evaluated separately, naturally heavier rainfall over a wide region on days when the north target area was seeded produced the appearance of increases in rainfall due to seeding in the north...
Inducing stable reversion to achieve cancer control

How can we stop cancer progression? Current strategies depend on modelling progression as the balanced outcome of mutations in, and expression of, tumour suppressor genes and oncogenes. New treatments emerge from successful attempts to tip that balance, but secondary mutational escape from those treatments has become a major impediment because it leads to resistance. In this Opinion article, we argue for a return to an earlier stratagem: tumour cell reversion. Treatments based on selection and analysis of stable revertants could create more durable remissions by reducing the selective pressure that leads to rapid drug resistance.
FAB Mass Spectrometry of Au25(SR)18 Nanoparticles

The molecular ion of the nanoparticle Au25(SCH2CH2Ph)18 (A25(SR)18) is observed at 7394 Da in fast atom bombardment (FAB, Xe atoms) ionization mass spectrometry using a 3-nitrobenzyl alcohol matrix. A distinctive pattern of positive fragment ions is evident in the mass interval 5225−7394 Da, where peaks are seen for successive mass losses equivalent to R2S entities. Because the Au25(SCH2CH2Ph)18 nanoparticle structure is crystallographically known to consist of a centered Au13 icosahedral core surrounded by six Au2(SR)3 semirings, the R2S loses are proposed to represent serial rearrangements and decompositions of the semiring structures. Mass losses equivalent to R2S2 and R2 entities also appear at the lower end of this mass interval. The most intense spectral peak, at m/z = 5246 Da, is assigned to the fragment Au25S10, from which all of the CH2CH2Ph organic units have been cleaved but from which no gold atoms have been lost. A different pattern of fragmentation is observed at lower masses, producing ions...
High intrachain order promotes triplet formation from recombination of long-lived polarons in poly(3-hexylthiophene) J-aggregate nanofibers.

Photoluminescence (PL) of single poly(3-hexylthiophene) (P3HT) J-aggregate nanofibers (NFs) exhibits strong quenching under intensity-modulated pulsed excitation. Initial PL intensities (I0) decay to steady-state levels (ISS) typically within ∼1–10 μs, and large quenching depths (I0/ISS >2) are observed for ∼70% of these NFs. Similar studies of polymorphic, H-aggregate type P3HT NFs show much smaller PL quenching depths (I0/ISS ≤1.2). P3HT chains in J-type NF π-stacks possess high intrachain order, which has been shown previously to promote the formation of long-lived, delocalized polarons. We propose that these species recombine nongeminately to triplets on time scales of >1 ns. The identity of triplets as the dominant PL quenchers was confirmed by subjecting NFs to oxygen, resulting in an instantaneous loss of triplet PL quenching (I0/ISS ∼1). The lower intrachain order in H-type NFs, similar to P3HT thin-film aggregates, localizes excitons and polarons, leading to efficient geminate recombination that ...
Visual diagnosis in emergency medicine: retrobulbar haemorrhage

On examination there was eyelid ecchymoses, chemosis and proptosis (figure 1). There was complete vision loss with preservation of light sense. The patient went to the operating room for emergent decompressive surgery. She regained full vision in her eye. …
Effects of dimethylsulfoxide on normal and burned dog skin.

Summary1. Dimethylsulfoxide swells collagen in the dermis and decreases the tensile strength of both normal and full-thickness burned dog skin, especially the latter. These effects are more pronounced with 100% than with 50% DMSO.2. The digestion of burned dog skin in vitro by elastase, collagenase, and protease is increased by pretreatment for 24 hr with 100% DMSO.3. Pretreatment for 24 hr with 100% DMSO not only increases the degree of digestion of partially denatured beef tendon collagen by enzymes, but also partially converts it to a form soluble in water and Tris buffer at pH 7.2.4. DMSO appears to be a denaturant of collagen, more active against burned and partially denatured collagen than against sclerocollagen.5. A continuous application of DMSO at 90%–100% concentrations for at least 24 hr might render full-thickness burn eschar more readily removed by solutes and might increase its susceptibility to enzymatic digestion.
Incorporation of Be dopant in GaAs core and core–shell nanowires by molecular beam epitaxy

Effective implementation of doped nanowires (NWs) in nanoscaled devices requires controlled and effective dopant incorporation. The one dimensional configuration of NWs poses a challenge for efficient doping due to the large number of surface states pinning the Fermi level close to the middle of the band gap and thus creating a large depletion layer at the surface. This effectively reduces the effective volume for doping. However, the flexibility of different architectures offered by the NWs, in particular, the core–shell configuration along with different growth mechanisms associated with the core and shell can be strategically used for efficient doping. In this work, the authors report on a catalyst free Ga-assisted approach for the growth of Be-doped GaAs NWs by molecular beam epitaxy. A systematic and a comprehensive study is reported using a variety of characterization techniques to determine the impact of NW configuration, Be cell temperature, and V/III beam equivalent pressure (BEP) ratio individua...
Effects of dipyridamole and methylprednisolone on intimal thickening in vein grafts

Fibrous intimal proliferation severe enough to produce occlusion has been observed in vein segments used for aorta-coronary bypass grafts. In an attempt to improve graft patency and decrease intimal fibrous thickening, animals with vein grafts were treated with dipyridamole or methylprednisolone for 8 to 12 weeks. Femoral vein segments were used to bypass the femoral artery in 36 dogs. Thirty-four of these grafts were patent at 8 weeks, with no statistically significant differences between control and drug treatment groups. Intimal thickness measurements were taken at three different points along the graft: proximal (upstream end), middle, and distal (downstream end). Dogs treated with methylprednisolone had significantly less intimal thickening (214 versus 125 μ, p
Feydeau on Stage

By the time Feydeau was writing his mature works many theatres in Paris had stopped specialising in a particular genre. Under the impact of the star system and the long run, theatres tended no longer to employ a steady troupe of actors. This did not seriously affect Feydeau, who gave his major plays to two theatres, both of which continued the earlier practice of actors specialising in lines of business. The Palais-Royal was, of course, the old home of Labiche and rightly welcomed the plays of the new king of vaudeville. A number of Feydeau’s greatest successes, including Champignol malgre lui, La Dame de chez Maxim and La Puce a Vorielle, were performed at a relatively new theatre, with the fitting name of Les Nouveautes. Founded in 1876, it had at first limited itself to operettas. In 1891, under the new management of Micheau, it began to produce vaudeville, and was so eminently successful that the annual theatrical records published in 1900 pointed out that, whereas most plays were considered to be a major success if they totalled one hundred performances, the nine plays produced by Micheau in the past decade (including three by Feydeau) had averaged three hundred performances.
The future of EUV lithography

Summary form only given. Extreme ultraviolet lithography (EUVL) is the exposure technology of choice to succeed optical lithography for volume semiconductor manufacturing at feature sizes below 50 nm. EUVL uses radiation at 13.5 nm from a plasma source to project an image using reflective optics and a reflective mask.
SoTL Champions: Leveraging Their Lessons Learned

The benefits of conducting SoTL impact individual faculty, staff, students, as well as disciplines, departments, and institutions. In spite of these benefits, colleges and universities, as well as faculty members, do not consistently embrace a broader vision of scholarship, including SoTL. This research explored individual experiences within the institutional framework of one land-grant institution to further institutionalize SoTL practice. A qualitative methodology of individual, semi-structured interviews was used to collect data. Eighteen faculty members with ranks from assistant to full professor revealed why they became involved in SoTL and the personal and professional benefits that went beyond those that “counted” for promotion and tenure decisions. Institutionalizing SoTL through definition and valuing in the faculty handbook and exempt review opportunities enabled SoTL work. Suggestions for strategically using SoTL to promote the university in efforts to increase recruitment and retention were offered.
High frequency, multi-axis dynamic stiffness analysis of a fractionally damped elastomeric isolator using continuous system theory

Abstract A spectral element approach is proposed to determine the multi-axis dynamic stiffness terms of elastomeric isolators with fractional damping over a broad range of frequencies. The dynamic properties of a class of cylindrical isolators are modeled by using the continuous system theory in terms of homogeneous rods or Timoshenko beams. The transfer matrix type dynamic stiffness expressions are developed from exact harmonic solutions given translational or rotational displacement excitations. Broadband dynamic stiffness magnitudes (say up to 5 kHz) are computationally verified for axial, torsional, shear, flexural, and coupled stiffness terms using a finite element model. Some discrepancies are found between finite element and spectral element models for the axial and flexural motions, illustrating certain limitations of each method. Experimental validation is provided for an isolator with two cylindrical elements (that work primarily in the shear mode) using dynamic measurements, as reported in the prior literature, up to 600 Hz. Superiority of the fractional damping formulation over structural or viscous damping models is illustrated via experimental validation. Finally, the strengths and limitations of the spectral element approach are briefly discussed.

Defending the Restatement of the Law, Liability Insurance: "Regulatory Considerations"

As the Restatement of the Law, Liability Insurance (“the Restatement”) has progressed through the rigorous drafting process of the American Law Institute (the “ALI”), insurance industry organizations have funded several public critiques of the Restatement. In this essay, we address one of the critiques funded by the National Association of Mutual Insurance Companies: a white paper prepared by Eric Dinallo and Keith Slattery (“D&S”) that criticizes the Restatement based on “regulatory considerations.” Their overarching claim is that the Restatement adopts a series of rules that are not based on the existing case law and that, if adopted by the ALI, would greatly expand the coverage owed by property-casualty insurers and encroach on the regulatory function of state insurance regulators. The result, they argue, will be a disruption in insurance markets, including premium increases, coverage withdrawals, significant additions to loss reserves, and general market instability. As we will demonstrate, these assertions are false, unsupported by any proffered evidence, or confused and misleading. Every rule of insurance law adopted in the Restatement is grounded in existing case law; most of the rules have been adopted in most jurisdictions; and all the rules, as well as all the commentary supporting those rules, are the product of the famously thorough ALI Restatement process, which includes many opportunities for experts in the field to review, comment on, and suggest revisions to drafts. Moreover, none of the rules adopted in the Restatement encroach or usurp the role of state insurance regulators. To the contrary, as demonstrated by the fact that all the rules the Restatement adopts are already in effect in multiple jurisdictions, those rules are compatible with, and complementary to, the regulatory role of state offices of insurance regulation. Further, D&S do not offer any evidence in support of their claim regarding adverse effects on the insurance market. All they offer is their own opinions, which are grounded in the mischaracterizations and confused analysis that we describe.
Relieving the Pressure on Tissue Development.

Understanding how tissue patterning emerges during embryogenesis is a long-standing goal of developmental biology. In particular, the complex interplay between extracellular and intracellular mechanical forces and biochemical cues that lead to cellular differentiation and ultimately adult tissue remains an active area of investigation. One of the main challenges has been that experimental methods that allow for the simultaneous measurement of mechanical force and biochemical signaling are limited.

Expression of enhancer of zeste homolog 2 (EZH2) protein in histiocytic and dendritic cell neoplasms with evidence for p-ERK1/2-related, but not MYC- or p-STAT3-related cell signaling

EZH2 is an important enzymatic subunit of the epigenetic regulator polycomb repressive complex 2 (PRC2), which controls gene silencing through post-translational modification, and is overexpressed in various carcinomas and hematopoietic neoplasms. We found that the majority of cases of histiocytic and dendritic cell neoplasms, including histiocytic sarcoma, follicular dendritic cell sarcoma, Langerhans cell histiocytosis, and interdigitating dendritic cell sarcoma, show strong EZH2 expression by immunohistochemical staining, in contrast to benign histiocytic lesions and normal cellular counterparts, which did not show EZH2 expression, suggesting that this molecule may function as an oncogenic protein in these neoplasms. We correlated EZH2 expression with that of p-ERK1/2, MYC, and p-STAT3, potential regulators of EZH2, and found that 60-80% of these cases showed strong p-ERK1/2 expression, and only a minority of cases showed positivity for MYC or p-STAT3 in neoplastic cells. In cases of follicular dendritic cell sarcoma, Langerhans cell histiocytosis, histiocytic sarcoma, and interdigitating dendritic cell sarcoma with strong EZH2 expression, 90%, 89%, 70%, and 100% of cases showed co-expression of p-ERK1/2 with EZH2, respectively, while only a small percentage of these cases showed MYC or p-STAT3 co-expression with EZH2 (≤30%). These findings suggest that the p-ERK1/2 signaling cascade, but not the p-STAT3 and MYC signaling cascades, may regulate EZH2 expression in histiocytic and dendritic cell neoplasms, and that EZH2 and the p-ERK1/2 signaling cascade could serve as therapeutic targets for the treatment of these neoplasms. Interestingly, only a minority of cases of blastic plasmacytoid dendritic cell neoplasm exhibited high EZH2 expression, and only a minority of these cases showed p-ERK1/2 co-expression, suggesting that alternative mechanisms may contribute to tumorigenesis in this aggressive neoplasm.
Effect of dangling side branching of polymer electrolyte membrane at the electrode interface on enhancement of ionic conductivity and capacity retention

The present article is aimed at improvement of ionic conductivity of solid polymer electrolyte membrane (PEM) via attachment of dangling polyethylene glycol methyl ether acrylate side branches to polyethylene glycol diacrylate network by reducing glass transition temperature (Tg) of the network. Moreover, excellent capacity retention of the PEM has been achieved owing to highly mobile side branches (i.e. lower Tg) at the PEM/electrodes interface, which probably prevents irreversible redox reaction at the solid electrolyte interface. Chemical/modifier doping is also found to be effective strategy to improve capacity retention via the modified PEM/electrode interface.
Safety of Combined Immunotherapy and Thoracic Radiation Therapy: Analysis of 3 Single-Institutional Phase I/II Trials.

Purpose The safety of combined immunotherapy and thoracic radiation therapy (iRT) has been understudied. We evaluated toxicities in patients receiving iRT from 3 single-institutional phase 1/2 trials. Methods and Materials Clinical/treatment characteristics and toxicities (per the Common Toxicity Criteria for Adverse Events, version 4.0) were extracted. For purposes of this analysis, groupings were made into (1) patients receiving immunotherapy plus stereotactic body radiation therapy (50 Gy/4 fractions or 60 Gy/10 fractions), (2) immunotherapy plus 45 Gy/15 fractions, and (3) twice-daily chemoimmunoradiotherapy (45 Gy in twice-daily fractions). Results None of the 60 patients undergoing immunotherapy plus stereotactic body radiation therapy (50 Gy, n = 49; 60 Gy, n = 11) experienced grade ≥4 events. There were 34 instances of any grade 3 event (in 15 total patients), with 9 pulmonary specific grade 3 events (in 4 patients). In the patients receiving 45 Gy/15 fractions (small cell lung cancers, n = 26; non-small cell lung cancers, n = 27), there were 2 grade 4 events (in the same patient), along with 17 grade 3 toxicities experienced by 10 total patients (2 pulmonary specific). Lastly, in the twice-daily cohort (n = 22), there were 5 grade 4 events (3 of which occurred in 1 patient) and 16 grade 3 toxicities occurring in 8 total patients (half of which were hematologic). Conclusions Administration of combined iRT is safe in the short term. Toxicities did not appreciably associate with demographics or dosimetry.
