Electromechanical Modeling and Experimental Validation of a Dual-Transduction Electrodynamic Wireless Power Receiver

We present the characterization and an experimentally validated electromechanical model of a dual-transduction receiver for an electrodynamic wireless power transmission (EWPT) system. The receiver makes use of both piezoelectric and electrodynamic transducers to generate electrical power simultaneously while operating at its torsion mode mechanical resonance (∼744 Hz). The system behavior and output performance under low-frequency, magnetic near-fields are analyzed by establishing an equivalent lumped-element circuit model. A prototype device is fabricated, characterized, and the experimental results are compared with the model predictions under various loading and input conditions. This chip-sized (0.09 cm3), volume-efficient design offers a low-profile and compact footprint for wearable and implantable medical devices applications.
A New Approach for Power Transformer Internal Faults Analysis Based on Magnetic Potential Balance Principle Calculation

Due to the longitudinal coupling of power transformer windings, the internal fault analysis become difficult and complicated. This paper presents a new approach base on magnetic potential balance principle calculation. When the internal fault occurs, it can extract useful information from the fault recorded diagram, analyze the fault type, and even lock the fault location. There is no need to build complex equations and models. In the end, the effectiveness of the method is proved by a case study.
Metabolism of 20-hydroxyeicosatetraenoic acid by cyclooxygenase. Formation and identification of novel endothelium-dependent vasoconstrictor metabolites.

Abstract We recently demonstrated that 20-hydroxyeicosatetraenoic acid (20-HETE) constricts rat aortic rings. The contractile response was partially dependent on the presence of endothelium and was abolished by pretreatment of the rings with either indomethacin or the endoperoxide/thromboxane receptor antagonist, SQ29548. Addition of GSH or SnCl2 to the organ bath diminished the contractile response of 20-HETE, whereas preincubation of the rings with a thromboxane synthase inhibitor did not affect the 20-HETE induced contractions. Short time incubation (2 min) of 20-HETE with ram seminal vesicle microsomes in the presence of p-hydroxymercurybenzoate yielded metabolites which migrated similarly on thin layer chromatography to the known arachidonate endoperoxides prostaglandin (PG) G2 and PGH2 and possess vasoconstrictory properties. The vasoconstriction was dose-dependent with a half-life of approximately 6.3 +/- 0.6 min. Addition of SQ29548 to the aortic ring bath 1 min after metabolite elicited vasoconstriction produced immediate relaxation. Furthermore, pretreatment of the rings with SQ29548 totally abolished the contraction. SnCl2 reduction of the metabolites produced in incubation of rat seminal vesicles with 20-HETE and p-hydroxymercurybenzoate resulted in a single radioactive peak which was further identified by gas chromatography/mass spectrometry as 20-hydroxy-PGF2 alpha. The inhibitory effect of SQ29548, the appearance of labile metabolites with a half-life of approximately 6 min and the production of 20-hydroxy-PGF2 alpha by SnCl2 reduction clearly indicate that the vasoconstrictor metabolites of 20-HETE are the labile endoperoxides of 20-HETE, 20-hydroxy-PGG2, and 20-hydroxy-PGH2.
Embedded Ultrasonic NDE with Piezoelectric Wafer Active Sensors

The use of piezoelectric wafer active sensors (PWAS) for embedded ultrasonic nondestructive evaluation (NDE) is described. PWAS structure and principle of operation are presented. The interaction between PWAS and ultrasonic Lamb waves is modeled and analyzed, and excitation "sweet spots" for preferentially exciting certain Lamb wave modes are identified. Recent trends in guided-wave ultrasonic NDE and damage identification are briefly reviewed. Then, the use of PWAS for embedded pulse-echo detection of structural cracks is exemplified. For large area interrogation, PWAS phased arrays are used in conjunction with the embedded ultrasonics structural radar (EUSR) algorithm to create scanning Lamb wave beams. For local area interrogation, the use of PWAS in conjunction with the electromechanical (E/M) impedance method is discussed with examples of local area crack detection in circular plates and aircraft panels. Spectral classification methods based on overall statistics and neural networks are discussed. Passive PWAS usage for acoustic emission and impact detection is presented. The use of PWAS for Rayleigh wave ultrasonics is also illustrated. Finally, we evaluate the role and opportunities of PWAS as the enabling technology for large area structural health monitoring, damage detection, and embedded NDE.
Optical reference receiver calibration for real time oscilloscopes

The filter is applied to the acquired waveform data from the O/E converter. This is done at the maximum real time sample rate of the oscilloscope. Lower frequency standards are highly over sampled. Therefore, floating point math is used for the filter convolution. This over sampling allows the bandwidth of the oscilloscope channel to operate as an anti-alias filter. From this point the filtered data is placed into a waveform database to create the source for the eye diagram that will appear on screen with the optical mask standard.
Induction of Humoral and CD8+ T Cell Responses Are Required for Protection against Lethal Ebola Virus Infection

Ebola virus (EBOV)-like particles (eVLP), composed of the EBOV glycoprotein and matrix viral protein (VP)40 with a lipid membrane, are a highly efficacious method of immunization against EBOV infection. The exact requirements for immunity against EBOV infection are poorly defined at this time. The goal of this work was to determine the requirements for EBOV immunity following eVLP vaccination. Vaccination of BALB/c or C57BL/6 mice with eVLPs in conjunction with QS-21 adjuvant resulted in mixed IgG subclass responses, a Th1-like memory cytokine response, and protection from lethal EBOV challenge. Further, this vaccination schedule led to the generation of both CD4 + and CD8 + IFN-γ + T cells recognizing specific peptides within glycoprotein and VP40. The transfer of both serum and splenocytes, but not serum or splenocytes alone, from eVLP-vaccinated mice conferred protection against lethal EBOV infection in these studies. B cells were required for eVLP-mediated immunity to EBOV because B cell-deficient mice vaccinated with eVLPs were not protected from lethal EBOV challenge. We also found that CD8 + , but not CD4 + , T cells are absolutely required for eVLP-mediated protection against EBOV infection. Further, eVLP-induced protective mechanisms were perforin-independent, but IFN-γ-dependent. Taken together, both EBOV-specific humoral and cytotoxic CD8 + T cell responses are critical to mediate protection against filoviruses following eVLP vaccination.
Planning for distributed execution through use of probabilistic opponent models

In multiagent domains with adversarial and cooperative team agents, team agents should be adaptive to the current environment and opponent. We introduce an online method to provide the agents with team plans that a "coach" agent generates in response to the specific opponents. The coach agent can observe the agents' behaviors but it has only periodic communication with the rest of the team. The coach uses a Simple Temporal Network(Dechter, Meiri, & Pearl 1991) to represent team plans as coordinated movements among the multiple agents and the coach searches for an opponent-dependent plan for its teammates. This plan is then communicated to the agents, who execute the plan in a distributed fashion, using information from the plan to maintain consistency among the team members. In order for these plans to be effective and adaptive, models of opponent movement are used in the planning. The coach is then able to quickly select between different models online by using a Bayesian style update on a probability distribution over the models. Planning then uses the model which is found to be the most likely. The system is fully implemented in a simulated robotic soccer environment. In several recent games with completely unknown adversarial teams, the approach demonstrated a visible adaptation to the different teams.
Integrating communication skill into the engineering curriculum (addressing communication issues from three directions)

Summary form only given. Over the past few years we have tried to focus on relevant issues concerning engineering from the viewpoint of administrators, faculty, students, staff and industry. We feel that it is important to address common needs and individual desires in order to achieve the best that we can accomplish in the area of communication. With this mind, we looked at what we were doing in the realm of teaching and promoting technical communication in our courses. A number of critical issues were noticed. We decided to propose, plan, and implement procedures that would address all the concerns and utilize the positive elements of our program to improve the communication skills of both our undergraduate and graduate population. The means to achieve acceptance by the faculty and students is addressed, along with the detailing of the careful planning for the important utilization of the graduate teaching assistant population as the catalyst for making the operation successful. Adaptable to most schools, the present plan enables faculty to realize that they can teach good communication skills, makes students aware of the fact that they can competently both produce and present technical documents, utilizes graduate assistants to provide a vital service to the undergraduate population, and explains the need for an entity within the department to direct the process.
Evaluation of two-year Jewish genetic disease screening program in Atlanta: insight into community genetic screening approaches

Improvements in genetic testing technologies have led to the development of expanded carrier screening panels for the Ashkenazi Jewish population; however, there are major inconsistencies in current screening practices. A 2-year pilot program was launched in Atlanta in 2010 to promote and facilitate screening for 19 Jewish genetic diseases. We analyzed data from this program, including participant demographics and outreach efforts. This retrospective analysis is based on a de-identified dataset of 724 screenees. Data were obtained through medical chart review and questionnaires and included demographic information, screening results, response to outreach efforts, and follow-up behavior and preferences. We applied descriptive analysis, chi-square tests, and logistic regression to analyze the data and compare findings with published literature. The majority of participants indicated that they were not pregnant or did not have a partner who was pregnant were affiliated with Jewish organizations and reported 100 % AJ ancestry. Overall, carrier frequency was 1 in 3.9. Friends, rabbis, and family members were the most common influencers of the decision to receive screening. People who were older, had a history of pregnancy, and had been previously screened were more likely to educate others (all p < 0.05). Analysis of this 2-year program indicated that people who are ready to have children or expand their families are more likely to get screened and encourage others to be screened. The most effective outreach efforts targeted influencers who then encouraged screening in the target population. Educating influencers and increasing overall awareness were the most effective outreach strategies.
How Do You Know You're Old? Gender Differences in Cues Triggering the Experience of Personal Aging.

In order to evaluate the gender differences on the experience of aging, 142 individuals 50 years of age and older completed an interview regarding experiences with another individual conveying the message that they were “old.” Interviewees were asked about the type of situation, the age and gender of the response person, and the perceived intent and feelings associated with the experience. Results showed that 72.3% of the experiences could be classified into one of three categories: discount/benefit, physical features/appearance, and performance. While no gender differences were found in the location/setting of the incident, the response person, or the age of the response person, findings indicated that for men, the incident was classified as a “benefit/discount,” while for women it was classified as “physical features/appearance.” In addition, the presumed intent of the situation was viewed as negative and hurtful by women, and both genders reported that the incident made them feel self-conscious and/or ...
HYDROGEN EFFECTS ON THE BURST PROPERTIES OF TYPE 304L STAINLESS STEEL FLAWED VESSELS

The effects of hydrogen and burst media on the burst properties of Type 304L stainless steel vessels were investigated. The purpose of the study was to compare the burst properties of hydrogen-charged stainless steel vessels burst with different media: water, helium gas, and deuterium gas. A second purpose was to provide data to improve an existing finite-element model for predicting burst behavior. Burst tests were conducted on hydrogen-charged and uncharged axially-flawed cylindrical vessels. The results indicate that samples burst pneumatically had lower volume ductility than those tested hydraulically. For pneumatic burst tests, samples burst with deuterium gas had slightly lower ductility than helium gas tests. For uncharged samples, burst pressure was not affected by burst media. For samples pre-charged with hydrogen, deuterium burst pressures were about 80% of the hydraulic or helium burst pressures. Hydrogen-charged samples had lower volume ductility and slightly higher burst pressures than uncharged samples. The results of the tests were used to verify and improve a previously developed predictive finite-element model. The existing finite-element model can qualitatively predict the expected changes in burst properties with hydrogen or tritium service, but a better material property database is required for quantitative predictions.Copyright © 2008 by Washington Savannah River Company LLC
Testing for Faults in Wiring Networks

An algorithm is derived for multiprobe testing for shorts, opens, and wiring errors in any multiterminal wiring network, such as a printed circuit board, wiring harness, multiconductor cable, or backplane wiring board. For behavioral testing the minimum number of tests required, always achievable, is equal to p - 1 + [log 2 q], where p is the number of terminals in the largest interconnected cluster in the network, and q is the total number of clusters, including isolated terminals. For structural testing the number of tests required is less, and can be as small as [log 2 q] + 1 depending upon the assumptions made regarding the types of faults that can occur.
Spin observables in electron deuteron interactions

Abstract Recent experiments studying spin degrees of freedom in electron interactions with the deuteron are described. The data obtained allow separation for the first time of the deuteron monopole and quadrupole form factor up to q 2 = 1 GeV 2 C 2 and yield new information on the neutron electric form factor.

Knowledge and the educative functions of a university: designing the curriculum of higher education

One of the missions of a university is the creation and dissemination of knowledge. Because this work is traditionally divided among scores or even hundreds of academic and research units for the convenience of the producing scholars and the orderly retrieval of this knowledge, the problem of introducing university students to the world of knowledge is frequently seen as a non-problem, at least in the US. That is, all that is necessary, it is assumed, is for students to be exposed to work in the existing academic units one-by-one, or in some combination. Curricular requirements in US universities generally call for matriculation in a selection of courses oA ered in the various units designated by reference to some general educational rationale or specialized educational purpose. However, an examination of almost any US university’s curricular goals or expectations and the actual courses taken by particular students demonstrates signi® cant discontinuities between the rationale and the actuality, between the intentions of general or specialized education and the knowledge made available in the courses taken. A major reason for the existence of these discontinuities, I contend, lies with the assumption that the organization of the curriculum of higher education should be done in the same manner that the university organizes to do its research and knowledge production. I suggest that this is a faulty premise upon which to organize the curriculum, and that there are better ways to introduce students to a university’s store of knowledge than by this traditional approach, ways that can bring educational purposes and actual learning more in line with each other and, at the same time, maintain
APPLICATIONS OF THE ALGEBRA OF CURRENT COMPONENTS

In the previous letter, the authors discussed the theoretical basis of approximate symmetries and suggested that a non-chiral U(6) x U{6) should be a "good symmetry" of the hadrons at rest [1].
Architectures of small satellite programs in developing countries

Abstract Global participation in space activity is growing as satellite technology matures and spreads. Countries in Africa, Asia and Latin America are creating or reinvigorating national satellite programs. These countries are building local capability in space through technological learning. This paper analyzes implementation approaches in small satellite programs within developing countries. The study addresses diverse examples of approaches used to master, adapt, diffuse and apply satellite technology in emerging countries. The work focuses on government programs that represent the nation and deliver services that provide public goods such as environmental monitoring. An original framework developed by the authors examines implementation approaches and contextual factors using the concept of Systems Architecture. The Systems Architecture analysis defines the satellite programs as systems within a context which execute functions via forms in order to achieve stakeholder objectives. These Systems Architecture definitions are applied to case studies of six satellite projects executed by countries in Africa and Asia. The architectural models used by these countries in various projects reveal patterns in the areas of training, technical specifications and partnership style. Based on these patterns, three Archetypal Project Architectures are defined which link the contextual factors to the implementation approaches. The three Archetypal Project Architectures lead to distinct opportunities for training, capability building and end user services.
A model-based approach to understanding school status of students with epilepsy

Abstract This study constitutes a preliminary test of a theoretical model proposed by Sexson and Madan-Swain to explain the school status of students with epilepsy. Sixty-six classroom teachers participated in the study, as did 74 of their students with epilepsy. Three predictor variables–teachers' attitude towards persons with epilepsy, teachers' training in instructing students with epilepsy, and students' seizure frequency–were examined. Consistent with the model, the three variables collectively predicted attendance (F = 54.48, p
Biharmonic density estimate — A scale space signature for deformable surfaces

A novel intrinsic geometric scale space formulation for 3D deformable surfaces termed as the Biharmonic Density Estimate (BDE) is proposed. The proposed BDE signature allows for multiscale surface feature-based representation of deformable 3D shapes for subsequent image and scene analysis. It is shown to provide an underlying theoretical framework for the concept of intrinsic geometric scale space, resulting in a highly descriptive characterization of both, the local surface structure and the global metric of the 3D shape. The compactness and robustness of the proposed BDE signature are demonstrated via a series of experiments and a key components detection application.
Does the Frame of a Comparative Ad Moderate the Effectiveness of Extrinsic Information Cues

This research investigates how framing moderates the use of message cues on performance risk evaluations. Understanding the moderating impact of the frame is important from a theoretical perspective as the frame is a critical contingency factor in how evaluations are formed. This research extends previous results by testing whether framing affects the use of other extrinsic cues, determining the effect when there are multiple extrinsic cues, determining the impact when extrinsic information is not explicitly provided, and providing evidence that positively framed messages engender more thorough analysis of message cues than negatively framed messages and affect how extrinsic cues are used.
Cocaine self-administration behaviors in ClockΔ19 mice.

Rationale A key role has been identified for the circadian locomotor output cycles kaput (Clock) gene in the regulation of drug reward. Mice bearing a dominant negative mutation in the Clock gene (ClockΔ19 mice) exhibit increased cocaine-induced conditioned place preference, reduced anxiety- and depression-like behavior, increased sensitivity to intracranial self-stimulation, and increased dopaminergic cell activity in the ventral tegmental area.
Autocrine/paracrine determinants of strain-activated brain natriuretic peptide gene expression in cultured cardiac myocytes.

Abstract The application of mechanical strain leads to activation of human brain natriuretic peptide gene promoter activity, a marker of hypertrophy, in cultured neonatal rat ventricular myocytes. We have used a combination of transient transfection analysis and reverse transcriptase-polymerase chain reaction to examine the role of locally produced factors in contributing to this activation. Conditioned media from strained, but not static, cultures led to a dose-dependent increase in human brain natriuretic peptide gene promoter activity. This increase was completely blocked by losartan or BQ-123, implying a role for angiotensin and endothelin as autocrine/paracrine mediators of the response to strain. Inclusion of the same antagonists in the cultures themselves led to only partial inhibition (∼60%), whereas inclusion of exogenous endothelin or angiotensin II resulted in amplification of the strain response. Angiotensin II and endothelin appear to be arrayed in series in the regulatory circuitry; the angiotensin response was blocked by BQ-123, whereas the endothelin response was unaffected by losartan. Mechanical strain was also shown to stimulate expression of the endogenous angiotensinogen, angiotensin-converting enzyme, and endothelin genes in this system. Collectively, these data indicate that locally generated angiotensin II and endothelin, acting in series, play an important autocrine/paracrine role in mediating strain-dependent activation of cardiac-specific gene expression.
The spectral selectivity of conducting micromeshes

Abstract The intrinsic absorption produced by the texture and finite conductivity of thin micromeshes is shown to severely limit their potential as a new class of heat mirrors. For semiconducting meshes it is shown that a 90% transmissivity in the solar spectral region is not compatible with a 90% reflectivity in the thermal re-radiation region while for metallic meshes only Al and Mg with submicron wire diameters ( ≈0.1 μ m ) show a potential improvement in selectivity over that obtained with thin metallic films.
DISCORD IN POSSIBILITY THEORY

A function referred to as discord was recently introduced as a justifiable measure of one type of uncertainty in the Dempster-Shafer theory, uncertainty that results from conflicts among evidential claims. In this paper, we investigate mathematical properties of this function within the domain of possibility theory. We show, in particular, that the largest value of discord in possibility theory is about 0.892. This result implies that discord is negligible (in comparison with nonspecificity) in many practical applications of possibility theory, especially when large bodies of evidence are involved.
Food Habits of the Yellowstone Whitefish Prosopium Williamsoni Cismontanus (Jordan)

Abstract A quantitative analysis of the food habits of 385 whitefish (Prosopium williamsoni cismontanus (Jordan)) and 52 trout from the Yellowstone and Gallatin Rivers was made. Collections were taken over a period of 1 year beginning in September, 1947, on the Yellowstone and on the Gallatin Rivers. Fingerling whitefish used the same food organisms as did adults but consumed smaller numbers and sizes. There was no important difference in the kinds of foods eaten by whitefish of different lengths. Caddis larvae and stonefly nymphs made up about equal parts of the whitefish diet. Midges were next in importance and mayflies comprised the smallest volume. Caddisflies and Diptera larvae together constituted 87 percent of the total number of organisms consumed. Whitefish in the Yellowstone ate mostly immature caddisand stoneflies, while the Gallatin fish utilized caddis, fish eggs, Diptera, stoneflies, and mayflies in more nearly equal amounts. Seasonal variations found in the diet of whitefish show that caddi...
ANOMALONS AS PINEUTS BOUND TO NUCLEAR FRAGMENTS: A POSSIBLE EXPLANATION

Abstract We suggest that the properties of anomalons, the highly reactive heavy-ion reaction fragments observed in emulsions, can be explained by considering them to be “pineuts”, i.e., a π − bound hadronically to a neutron cloud extending out from the nuclear fragment.
Subjectivity in parent-infant relationships: A discussion of internal working models

Bowlby (1969/1982, 1973, 1980) has proposed that internal working models of self and other are psychic structures that guide an individual's subjective experience of and responses to others in important relationships. They are termed “working” models because they are believed to be dynamic mental representations that are modifiable, although they are presumed to become more resistant to change after the early years. This paper reviews Bowlby's construct of internal working models, including some recent empirical evidence usefully explained by the construct. The authors apply the construct of working models to parents' subjective experiences of their infants and review some preliminary evidence that suggests that parental working models of their infants are present even prior to the infants' birth and influence the parents' perception and interpretation of the infants' characteristics and behaviors. The authors then consider the development of infants' working models of self and other in the context of parental attributions. They conclude that subjectivity in parent-infant relationships is an exciting and promising area for investigation, although, at present, future progress is limited by problems of measurement. A brief discussion of directions for future research is included.
Survey of the background levels of PCDDs and PCDFs in UK vegetation

Abstract Samples of vegetation from various locations in the UK have been analysed to give PCDD and PCDF homologue group total concentrations, as part of a programme to investigate background levels in the UK environment. For most homologue groups, detectable levels were present in all samples.
Characteristics of Minority Group Families Who Have Tried to Move Into White Neighborhoods1

.— In a survey of 686 minority group families, there were 97, or 14 pet cent of the total sample, who had tried to move into white neighborhoods. Some of these had been successful, while the efforts of others had been thwarted for various reasons. An analysis of the characteristics of this 14 pet cent shows many interesting social as well as economic traits. The attitude that members of minority groups want to be isolated with their own finds little justification. Of particular interest are the deviations from the total survey group that this 14 per cent revealed.
Panic Attacks After Cessation of Phenoxybenzamine: a Case Report

AbstractA case is presented in which cessation of phenoxybenzamine, an a-adrenoceptor antagonist, is implicated in the development of spontaneous panic attacks in a man with no previous psychiatric history. A possible mechanism involving noradrenergic supersensitivity as the result of prolonged receptor blockade is discussed.
Further experience with seromuscular colocystoplasty lined with urothelium.

Purpose: We report our continuing experience with seromuscular colocystoplasty lined with urothelium. This procedure is designed to preserve the urothelium and potentially decrease the incidence of complications associated with standard bladder augmentation.Materials and Methods: We retrospectively reviewed the charts of 32 patients who underwent seromuscular colocystoplasty lined with urothelium between April 1994 and July 1999. Data were collected on patient demographics, surgical indications, previous and adjunctive surgical procedures, preoperative and postoperative urinary continence, upper urinary tract changes, urodynamic parameters, surgical complications and histological findings.Results: Mean patient age at surgery plus or minus standard deviation was 11.1 ± 4.8 years. Mean followup was 1.6 ± 1 years. A mean of 1.5 ± 0.9 years postoperatively urodynamic studies available in 28 cases showed that total and safe bladder capacity increased by 1.8 and 2.4-fold, respectively. Continence was achieved i...
Axion cold dark matter in view of BICEP2 results.

If the excess B-mode polarization measured by BICEP2 comes from inflationary gravitational waves then there are severe constraints on the mass and abundance of axionlike particles making up cold dark matter.
Partial Homogeneity in Locally Finite Groups

As a byproduct of his work on universal central extensions in [4], K. Hickin has constructed a very wide class of locally finite simple groups that satisfy a weakened version of (1.1). Specifically, if lr is a non-empty set of primes, Hickin's groups satisfy the condition (1.1) for finite :r-subgroups H and K, and are not f-homogeneous. It is this type of condition which we study in the sequel. Proceeding with necessary terminology, we have
Reactions and single-particle structure of nuclei near the drip lines

Abstract The techniques that have allowed the study of reactions of nuclei situated at or near the neutron or proton drip line are described. Nuclei situated just inside the drip line have low nucleon separation energies and, at most, a few bound states. If the angular momentum in addition is small, large halo states are formed where the wave function of the valency nucleon extends far beyond the nuclear radius. We begin with examples of the properties of nuclear halos and of their study in radioactive-beam experiments. We then turn to the continuum states existing above the particle threshold and also discuss the possibility of exciting them from the halo states in processes that may be thought of as “collateral damage”. Finally, we show that the experience from studies of halo states has pointed to knockout reactions as a new way to perform spectroscopic studies of more deeply bound non-halo states. Examples are given of measurements of l values and spectroscopic factors.
Copper Inhibits NMDA Receptor-Independent LTP and Modulates the Paired-Pulse Ratio after LTP in Mouse Hippocampal Slices

Copper misregulation has been implicated in the pathological processes underlying deterioration of learning and memory in Alzheimer's disease and other neurodegenerative disorders. Supporting this, inhibition of long-term potentiation (LTP) by copper (II) has been well established, but the exact mechanism is poorly characterized. It is thought that an interaction between copper and postsynaptic NMDA receptors is a major part of the mechanism; however, in this study, we found that copper (II) inhibited NMDA receptor-independent LTP in the CA3 region of hippocampal slices. In addition, in the CA3 and CA1 regions, copper modulated the paired-pulse ratio (PPR) in an LTP-dependent manner. Combined, this suggests the involvement of a presynaptic mechanism in the modulation of synaptic plasticity by copper. Inhibition of the copper-dependent changes in the PPR with cyclothiazide suggested that this may involve an interaction with the presynaptic AMPA receptors that regulate neurotransmitter release.

Neutrophil CD64 as a Diagnostic Marker of Sepsis: Impact on Neonatal Care

Objective The aim of this study is to determine the validity and reliability of neutrophil CD64 in identifying infected infants and to evaluate the impact of this marker on clinical care. Study Design Neutrophil CD64 index was incorporated in 371 infection evaluations in 234 infants (ages 1–293 days) from 2005 to 2009 and the impact of this change on clinical care was evaluated. Results The sensitivity of the neutrophil CD64 assay was 87% in identifying 31 episodes of culture positive sepsis and 83% in identifying 12 infants with ventilator-associated pneumonia. There was no difference in the mean number of antibiotic days in infants with a normal CD64 versus those with a normal complete blood count (CBC) ( p = 0.89), but twofold more infants were identified as “not infected” by CD64 than by CBC. Conclusion CD64 had a high sensitivity for identifying infected infants while also decreasing the number of infants that were exposed to unnecessary antibiotic use.
Characterization of operating parameters in the cleaning zone of microbubble column flotation

Abstract The behavior of bubble-particle aggregates in the cleaning zone of a flotation column is not well understood. Probably, they are governed by the operating parameters such as gas and wash water flow rates, wash water addition point and the length of cleaning zone. The parameters were characterized by the experimental work conducted on a micronized coal sample at various conditions.
Preservation of vision through Weiss ring after dense vitreous hemorrhage.

PURPOSE: To report an unusual case of retained vision through a Weiss ring in the setting of dense vitreous hemorrhage. METHOD: Case report of a 55-year-old woman with a 23-year history of type 1 diabetes mellitus who presented with new onset of blurred vision in the left eye as a result of a dense vitreous hemorrhage. RESULTS: The patient had received full scatter laser photocoagulation for proliferative diabetic retinopathy in the right eye several years earlier and reported previous resolving episodes of vitreous hemorrhage in the left eye. Best-corrected visual acuity in the left eye was hand motions at 3 feet. However, with careful head positioning visual acuity improved to 20/40 through a small clear central island. Examination of the left fundus showed a dense vitreous hemorrhage with a clear, mobile opening in the posterior hyaloid corresponding to the Weiss ring. The retina could be partially visualized only through the area of the Weiss ring. CONCLUSIONS: This unusual case demonstrates the anatomical relationship between the posterior hyaloid and Weiss ring.

Tools and tenets of schema therapy: toward the construct validity of the early maladaptive schema questionnaire–research version (EMSQ-R)

This study investigated the scale reliability, factor structure, and convergent validity of the Early Maladaptive Schema Questionnaire–Research Version (EMSQ-R), a 75-item self-report inventory that is a revised version of the Young Schema Questionnaire (YSQ) and that measures the presence and severity of 15 early maladaptive schemas (EMS), in an undergraduate sample of 292 participants. Eleven EMS scales were found to have adequate reliability, and 14 hypothesized EMS factors emerged during factor analysis. In addition, findings provided support for the underlying tenets of Schema Therapy (ST), by demonstrating correlations between EMS and measures of both adult attachment and childhood trauma. Future clinical and research directions are discussed. Copyright © 2004 John Wiley & Sons, Ltd.
Asymptotic Analysis Of The Total Least Squares ESPRIT Algorithm

This paper considers the problem of estimating the parameters of multiple narrowband signals arriving at an array of sensors. Modern approaches to this problem often involve costly procedures for calculating the estimates. The ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) algorithm was recently proposed as a means for obtaining accurate estimates without requiring a costly search of the parameter space. This method utilizes an array invariance to arrive at a computationally efficient multidimensional estimation procedure. Herein, the asymptotic distribution of the estimation error is derived for the Total Least Squares (TLS) version of ESPRIT. The Cramer-Rao Bound (CRB) for the ESPRIT problem formulation is also derived and found to coincide with the variance of the asymptotic distribution through numerical examples. The method is also compared to least squares ESPRIT and MUSIC as well as to the CRB for a calibrated array. Simulations indicate that the theoretic expressions can be used to accurately predict the performance of the algorithm.
Wireless Communication in Oil and Gas Wells

We review the techniques of below-ground wireless communication in the oil and gas industry. A historical and theoretical analysis of pressure wave and electromagnetic communication is presented. Case studies for both technologies and their current applications are evaluated to identify the limitations of each method and opportunities for innovation. Finally, the possibilities of smart well technology are discussed with focus on sensors powered wirelessly for the continuous monitoring of shale oil/gas reservoirs using electromagnetic methods. We conclude that the critical challenges are associated with powering the devices, which must perform for periods of months to years and must be able to generate sufficiently powerful signals to overcome the large signal attenuation associated with electromagnetic wave propagation through geological media.
Numerical simulation of the formation of brine pockets during the freezing of the NaCl - H2O compound from above

It is a well known fact that sea ice contains much less salt than the water from which it forms. Brine is rejected from the interior of the ice and removed at the interface through both diffusion and convection. A close observation of the interface between the ice and the liquid reveals the existence of drainage channels that extend into the ice. The “ice” is not solid, but rather a slush where both liquid and solid phases coexist. The liquid is trapped inside this mushy zone in the form of pockets, some of which originate at the interface. These pockets have been observed to form as a result of necking of the interfacial tubes as the ice grows. This phenomenon is numerically simulated in this paper, using the NaCl-H2O binary compound, along with a recently introduced continuum model. The results of this simulation compare favorably with published experimental observations.
Polynomial approximations to functionals in the theory of materials with memory

Pour une substance dotee de memoire, on peut quelquefois determiner approximativement, d'une maniere utile, la valeur fonctionelle Φ, qui relie l'effort a l'histoire de la doformation, par un polynome aux elements d'un espaceL de formes lineaires sur l'espaceF des histoires. Cette etude prolonge un resultat obtenu parChacon etRivlin, afin de demontrer comme possible une telle approximation dans tout ensemble borne pour la topologie donnee surF, et pour toute valeur fonctionelle Φ uniformement continue pour la topologie faible definie parL surF.
Tests of Homogeneity of Independent Correlation Coefficients.

It is demonstrated that tests of homogeneity of independent correlation coefficients based on the simple forms of the normal andt approximations to the distribution of the correlation coefficients are comparable in terms of robustness, size and power.
Naturally Occurring Changes in Physical Activity Are Inversely Related to Depressive Symptoms During Early Adolescence.

Objective We examined the relationship between naturally occurring changes in physical activity and depressive symptoms across a 2-year period among adolescent boys and girls. Methods Participants (N = 4594) reported their frequency of physical activity outside of school and completed the Center for Epidemiological Studies Depression scale in the Fall of 1998 (beginning of 7th grade; baseline data), Spring of 1999 (end of 7th grade; interim data), and Spring of 2000 (end of 8th grade; follow-up data). Results Latent growth modeling indicated that a 1 SD unit change in the frequency of leisure-time physical activity was inversely related to a.25 SD unit change in depressive symptoms. This relationship was attenuated but remained statistically significant when simultaneously controlling for the confounding variables of sex, socioeconomic status, smoking, alcohol consumption, and the value participants placed on their health, appearance, and achievement. Conclusions Naturally occurring changes in physical activity were negatively related with changes in depressive symptoms. The results encourage randomized controlled trials to experimentally determine whether an increase in physical activity reduces depression risk among adolescent boys and girls.
The fasting polypeptide FGF21 can enter brain from blood

FGF21 recently has been proposed as a missing link in the biology of fasting, raising the question of whether it directly reaches the brain. We used multiple time-regression analysis to quantify the influx rate of this polypeptide across the blood-brain barrier (BBB), size-exclusion chromatography to examine degradation, capillary depletion to differentiate entry into brain parenchyma from retention in the microvasculature, and measurement of efflux rate to determine a possible confounding effect on measurement of entry. FGF21 was 94 % intact in serum and 75 % in brain 10 min after intravenous bolus delivery. Its influx rate was 0.23 ± 0.12 μl/g-min, nearly 4-times faster than that of the vascular marker albumin. At 10 min, about 0.5 % of the administered FGF21 was present in a gram of brain tissue. Of this, 70 % reached the parenchyma of the brain. Co-injection of excess FGF21 failed to inhibit the influx, showing a lack of saturation. Efflux, which occurred at the same rate as the bulk reabsorption of cerebrospinal fluid, also was not saturable. In summary, FGF21 shows significant, non-saturable, unidirectional influx across the BBB.
Dental Plaque and Calculus: Risk Indicators for Their Formation

The aim of this study was to determine the levels of plaque and subgingival calculus accumulation and to evaluate their correlations with periodontal disease, as well as to evaluate the correlations with race, age, and gender in an attempt to identify risk indicators for plaque and calculus formation. A total of 508 adults 25-73 years of age was examined, and plaque assessment, gingival bleeding assessment, probing pocket depth, and attachment levels were determined. The mean percent visible plaque was 73.5% (range, 8.3-100%), mean percent of bleeding surfaces 38.5% (range, 0-100%), and the mean percent teeth with subgingival calculus 39.6% (range, 0-100%). The mean probing pocket depth in the group was 2.5 ± 0.6 mm (SD), and mean clinical attachment loss was 2.1 ± 1.1 mm. The majority (63%) were classified as having "Moderate" periodontal disease, 7% were "Healthy", and the remaining 30% had "Established" periodontal disease. Plaque and calculus showed statistically significant relationships to the three...
Shedding of the tumor necrosis factor (TNF) receptor from the surface of hepatocytes during sepsis limits inflammation through cGMP signaling.

Proteolytic cleavage of the tumor necrosis factor (TNF) receptor (TNFR) from the cell surface contributes to anti-inflammatory responses and may be beneficial in reducing the excessive inflammation associated with multiple organ failure and mortality during sepsis. Using a clinically relevant mouse model of polymicrobial abdominal sepsis, we found that the production of inducible nitric oxide synthase (iNOS) in hepatocytes led to the cyclic guanosine monophosphate (cGMP)–dependent activation of the protease TACE (TNF-converting enzyme) and the shedding of TNFR. Furthermore, treating mice with a cGMP analog after the induction of sepsis increased TNFR shedding and decreased systemic inflammation. Similarly, increasing the abundance of cGMP with a clinically approved phosphodiesterase 5 inhibitor (sildenafil) also decreased markers of systemic inflammation, protected against organ injury, and increased circulating amounts of TNFR1 in mice with sepsis. We further confirmed that a similar iNOS-cGMP-TACE pathway was required for TNFR1 shedding by human hepatocytes in response to the bacterial product lipopolysaccharide. Our data suggest that increasing the bioavailability of cGMP might be beneficial in ameliorating the inflammation associated with sepsis.
HIV-gp120 and physical dependence to buprenorphine.

Background Opioids are among the most effective and commonly used analgesics in clinical practice for severe pain. However, the use of opioid medications is clinically limited by several adverse properties including dependence. While opioid dependence is a complex health condition, the treatment of HIV-infected individuals with opioid dependence presents additional challenges. The goal of this study was to examine the physical dependence to buprenorphine in the context of HIV.
Cellular mobile packet radio using multiple-channel CSMA

One way to increase frequency spectrum utilisation in a mobile communication system is to divide the geographical region spatially into a number of cells, each of which contains a base station. Each base station is assigned a set of channels, and the users in the neighbourhood of a base station can transmit their messages to the base station. Several protocols governing the access to the base station channels are available. The paper considers multichannel CSMA schemes embedded in a spatially celluar communication environment. Several alternative ways of organising the system resources, layout and protocol are considered. The complexity of the system is progressively increased, culminating in the general case: each base station is assigned a set of Cachannels and users access any one of the k nearest base stations with multichannel CSMA protocol. The performance characteristics of the system?normalised delay against system bandwidth utilisation?are given in terms of the system parameters. The several configurations considered are compared based on the delay, band-width utilisation and interference rejection characteristics.
