Radio emission from X-ray binaries and the proto-type jets of SS433

We summarize the X-ray binaries that are known to exhibit radio emission and concentrate on SS433 as the proto-type of X-ray binaries with radio and optical emission from jet flows perpindicular to accretion disks. In the context of accretion onto compact objects, SS433 provides the most detailed information about high velocity (v = 78,000 km/sec), gas dynamical flows moving outward along accretion disk axes. A working hypothesis whereby the radio and optical jets are produced in an expanding sheath environment around flows perpindicular to an accretion disk is discussed, and the minor deviations from a simple twin-jet kinematical model are summarized. The longest time scale deviations from the simple kinematical model are shown to be consistent with a “beat model” in which the average 162.5d period of precession of the accretion disk is the harmonic mean of two periods of 175d and 152d, and the long time scale deviations from the kinematic model exhibit a beat difference period of − 2300d.
Evaluation of Heat-Damage to Protein by Coomassie Blue G Dye-binding

A rapid, simple method is described which may be useful for determination of heat-damage to proteins in processed foods. It uses the Coomassie Blue dye-binding (DB) capacity of food proteins extract-able in 0.2% KOH, with lysozyme as reference standard. The presence of glucose or lactose was essential to reduce DB capacity of casein on autoclaving. The DB capacity, on dried basis, of fat-free milk, whole egg, egg white, or blood was reduced rapidly with autoclaving, but not that of gelatin and gluten. The DB capacity of extracted soybean flakes, mung beans and black-eyed pea beans was reduced gradually as the time of autoclaving was increased.
Hunter syndrome (MPS II-B): a report of bilateral vitreous floaters and maculopathy.

Purpose: To describe bilateral vitreous opacities and maculopathy in a child with Hunter syndrome. Methods: A case involving fundus examination, photography, and optical coherence tomography. Medline and Embase searches found no reference to vitreous or macular abnormalities in Hunter syndrome. Results: A two-year-old boy with Hunter syndrome was found to have asymmetric, bilateral, free-floating vitreous opacities that remained stable over six years. Amblyopia and exotropia improved with occlusion therapy and spectacle correction. Visual acuity decreased when bilateral maculopathy supervened. Conclusion: Screening for vitreous abnormalities and maculopathy may be important in diagnosing, treating, and explaining visual loss in Hunter syndrome.
A Varactor and FMR-Tuned Wideband Band-Pass Filter Module With Versatile Frequency Tunability

A varactor and FMR-tuned wideband band-pass filter (BPF) module with versatile frequency tunability has been devised and realized on RT/Duroid substrate. By connecting four variable capacitance diodes (varactors) to the four open-circuited stubs of an X-band passive composite-BPF and adjusting the reverse bias voltage from 2 to 22 V, the 3 dB passband of the passive composite-BPF was continuously tuned from 7.7-12.4 GHz to 11.4-17.5 GHz. The corresponding bandwidth (BW) was enlarged from 4.7 to 6.1 GHz and the upper frequency of the passband was extended from 12.4 to 17.5 GHz, namely, a total frequency span of 9.8 GHz. The BW of the passive composite-BPF was further FMR-tuned using a pair of Band-Stop Filter (BSF). By setting the reverse bias voltage at 22 V together with the bias magnetic fields at 3250 and 4200 Oe, respectively, to the two BSFs, the 6.1 GHz BW and 9.8 GHz frequency span were compressed to 1.4 GHz toward the high-end frequency. The 4.7 GHz BW and 9.8 GHz frequency span were also compressed to 1.0 GHz toward the low-end frequency with 2650 and 3500 Oe bias magnetic fields and 2 V reverse bias voltage. Thus, the combination of the varactor and FMR-tuning has facilitated versatile passband and its BW tuning covering the X-and Ku-bands with both large frequency tunability and greatly improved frequency selectivity.
Sla2p Is Associated with the Yeast Cortical Actin Cytoskeleton via Redundant Localization Signals

Sla2p, also known as End4p and Mop2p, is the founding member of a widely conserved family of actin-binding proteins, a distinguishing feature of which is a C-terminal region homologous to the C terminus of talin. These proteins may function in actin cytoskeleton-mediated plasma membrane remodeling. A human homologue of Sla2p binds to huntingtin, the protein whose mutation results in Huntington’s disease. Here we establish by immunolocalization that Sla2p is a component of the yeast cortical actin cytoskeleton. Deletion analysis showed that Sla2p contains two separable regions, which can mediate association with the cortical actin cytoskeleton, and which can provide Sla2p function. One localization signal is actin based, whereas the other signal is independent of filamentous actin. Biochemical analysis showed that Sla2p exists as a dimer in vivo. Two-hybrid analysis revealed two intramolecular interactions mediated by coiled-coil domains. One of these interactions appears to underlie dimer formation. The other appears to contribute to the regulation of Sla2p distribution between the cytoplasm and plasma membrane. The data presented are used to develop a model for Sla2p regulation and interactions.
Effects of intraoperative reading on vigilance and workload during anesthesia care in an academic medical center.

Background: During routine cases, anesthesia providers may divert their attention away from direct patient care to read clinical (e.g., medical records) and/or nonclinical materials. The authors sought to ascertain the incidence of intraoperative reading and measure its effects on clinicians’ workload and vigilance. Methods: In 172 selected general anesthetic cases in an academic medical center, a trained observer categorized the anesthesia provider’s activities into 37 possible tasks. Vigilance was assessed by the response time to a randomly illuminated alarm light. Observer- and subject-reported workload were scored at random intervals. Data from Reading and Non-Reading Periods of the same cases were compared to each other and to matched cases that contained no observed reading. The cases were matched before data analysis on the basis of case complexity and anesthesia type. Results: Reading was observed in 35% of cases. In these 60 cases, providers read during 25 3% of maintenance but not during induction or emergence. While Non-Reading Cases (n 112) and Non-Reading Periods of Reading Cases did not differ in workload, vigilance, or task distribution, they both had significantly higher workload than Reading Periods. Vigilance was not different among the three groups. When reading, clinicians spent less time performing manual tasks, conversing with others, and recordkeeping. Conclusions: Anesthesia providers, even when being observed, read during a significant percentage of the maintenance period in many cases. However, reading occurred when workload was low and did not appear to affect a measure of vigilance. ROUTINE intraoperative anesthesia care, like aviation, has been described by some as consisting of “hours of boredom punctuated by moments of terror.” What is considered acceptable or professional behavior and activities during the uneventful periods of low clinical
What Is the Role of Theories in the Study of Schizophrenia

As an epilogue to the themed papers on "Theories of Schizophrenia" in this issue of Schizophrenia Bulletin, this article reviews some basic philosophy of science principles in regard to the role of theories in the evolving state of a natural science discipline. While in early phases inductive and abductive logic are the primary vehicles for organizing observations and developing models, when a critical set of "facts" have been elucidated which can be explained by competing theoretical perspectives, hypothetico-deductive logic provides a more robust and efficient approach to scientific progress. The key principle is to determine where two or more theories predict different observations and then to devise studies that collect critical observations-correlations or experimental outcomes that are predicted differentially by the competing theories. To a large extent, current theories of schizophrenia (eg, focusing on aberrant dopaminergic signaling, neural dysconnectivity, and disrupted neural development) are not (and are not intended by their authors to be) mutually exclusive of each other. Rather, they provide explanations that differ in relative emphases, eg, on distal vs proximal causes and on broad vs narrow behavioral end points. It is therefore possible for all of them to be "right" at least in a general sense. This non-exclusivity is problematic when considered in light of the strong inferences principles characteristic of a mature natural science discipline. The contrast points are likely to be found in constructions that integrate influences across different levels of analysis, as in additive vs interactive models, direct effects vs mediation models, and developmental vs deteriorative models.
The effect of particle size on the contact toxicity of insecticides to adult mosquitoes, Anopheles stephensi List.

The optimum size range of particles of two carbamates and two organophosphorus compounds in deposits on plywood and plaster for contact toxicity to blood-fed females of Anopheles stephensi List, was 5–30 µm. The effect of particle size on the contact toxicity of these compounds of high intrinsic toxicity was not great and in this respect resembled that found previously for dieldrin and γ BHC. In the few tests done, the concentration of active ingredient in wettable powder formulations was not an important factor in determining the contact toxicity of deposits of such toxic materials.
Supplemental relative clauses: Internal and external syntax

The internal syntactic structures of restrictive and non-restrictive relative clauses are largely identical. This paper argues that despite a uniform internal structure, the external distributions – specifically, linearization with respect to the head – of non-restrictive relative clauses are subject to several conditions. In particular, sentential non-restrictive relative clauses with which and what can appear to the left of their heads in limited (and distinct) syntactic contexts. These lexical and syntactic constraints are represented within the framework of Sign-based Construction Grammar. In light of these observations, the paper revisits claims about the internal structure of parenthetical as-clauses. Prior claims that as cannot be a relativizer are shown to be unfounded, and new data are presented in favor of treating them as relative clauses with the external distribution of sentential adverbials. This is possible given the ability to state separately specifications of construction-internal syntactic structure and construction-external linear-order constraints.
Black-white differences in plasma lipids and lipoproteins in adults: the Cincinnati Lipid Research Clinic population study.

Black—white lipoprotein differences were studied in 43 pairs of adult males and 51 pairs of adult females to test the hypothesis that in a heterogeneous suburban biethnic setting, blacks have higher levels of high density lipoprotein cholesterol (C-HDL), lower levels of low density lipoprotein cholesterol (C-LDL), and lower levels of triglyceride (TG) when pair-matched by total plasma cholesterol, age, and sex with whites. With essentially identical total plasma cholesterol levels and comparable degrees of ponderosity, black males had lower plasma TG (P < 0.05) and higher plasma C-HDL levels (P < 0.005). There were no significant male black—white differences in C-LDL, but the ratio of C-LDL to C-HDL was lower in black males (P < 0.01). There were no significant differences in any lipoprotein fractions or the C-LDL/C-HDL ratio between black and white females, although black females had slightly lower plasma TG and slightly higher C-HDL than white females.
ARIA: an adaptive and programmable media-flow architecture for interactive arts

We are developing an adaptive and programmable media-flow ARchitecture for Interactive Arts (ARIA) to enable real-time control of audio, video, and lighting on an intelligent stage. The intelligent stage is being equipped with a matrix of floor sensors for object localization, microphone arrays for sound localization, beam forming and motion capture system. ARIA system provides an interface for specifying intended mappings of the sensory inputs to audio-visual responses. Based on the specifications, the sensory inputs are streamed, filtered and fused, actuate a controllable projection system, sound surround and lighting system. The actuated responses take place in real-time and satisfy QoS requirements in live performance. In this paper, we present the ARIA quality-adaptive architecture. We model the basic information unit as a data object with a meta-data header and object payload streamed between nodes in the system and use a directed acyclic network to model media stream processing. We define performance metrics for the output precision, resource consumption, and end-to-end delay. The filters and fusion operators are being implemented by quality aware signal processing algorithms. The proper node behavior is chosen at runtime to achieve the QoS requirements and adapt to input object properties. For this purpose, ARIA utilizes a two-phase approach: static pre-optimization and dynamic run-time adaptation.
Morphologic Assessment of Recently Founded Populations of the Coyote, Canis latrans, in Tennessee

Recently founded populations of the coyote ( Canis latrans ) in Tennessee were assessed morphologically using multivariate-statistical procedures. Five pelage and 20 cranial measurements were used in the examination. Results supported C.l. frustror and C. l. thamnos as valid subspecies and indicated the presence of both taxa in Tennessee. These findings suggested a multiple origin for coyote populations in the newly colonized area. Because C.l. frustror was the predominant subspecies in the state, it appeared that Tennessee coyotes have a greater affinity with C.l. frustror than with C. l. thamnos . Spatial variation existed among the populations sampled in newly colonized areas of Tennessee and established portions of the range. Yet, these results provided little evidence to suggest a discrete morphologic size as the founder of the newly established populations or the disperser into Tennessee.
Intraneural lipoma of the ulnar nerve at the elbow: A case report and literature review

Intraneural lipomas of the ulnar nerve or its branches are rare benign tumours. Although most intraneural lipomas present as asymptomatic tumours, some may present as compression neuropathies due to their location. In the majority of cases these tumours can be enucleated without damage to the nerve fibres.
The Scope of Ethics

Ethics as Sidgwick understands it is ‘the science or study of what is right or what ought to be, so far as this depends upon the voluntary action of individuals’ (ME p. 4). Science here means a systematic study, which seeks to attain precise knowledge (see ME p. 1). But unlike such sciences as psychology or sociology, ethics deals not with mere facts, but with norms of action, expressed in terms of ‘ought’ or ‘right’. Some believe that ethics also deals with virtues, or a moral evaluation of a person’s character, rather than his or her actions; but one’s character is known to us only through his or her acts; and we usually do not separate an evaluation of someone’s character from that of his or her behavior (ME Bk. 1 Ch. 9 p. 113 fn. 1). Therefore, the primary subject of ethics is considered to be an individual’s actions. Another study that treats norms is politics; but unlike politics, which deals with the decision-making of a government, ethics deals with the actions of an individual. Thus Sidgwick’s primary concern is with individual decision-making, but he does not distinguish between individual acts done in public and those done in private.1
Rigid-plastic torsion of a hollow tube in strain-gradient plasticity

Abstract Closed-form expressions for the Cauchy stress, microstress, moment-stress, and the torque-twist relationship in a twisted hollow circular tube are derived for a rigid-plastic strain-gradient plasticity. This is accomplished for any of the gradient-enhanced effective plastic strain measures from a considered broad class of these measures. Numerical results are given and discussed for the two most frequently utilized measures and for the three adopted stress-strain relationships modeling the uniaxial tension test. Solid circular rods and thin-walled tubes are both considered. The existence of the line forces is also discussed from the standpoint of the basic equilibrium considerations and the principle of virtual work.
Light-matter interactions in aligned silver nanorod arrays

Abstract This study presents an experimental evaluation of the light-matter interactions in silver nanorod arrays of various lengths fabricated by electron-beam physical vapor deposition. The reflectance of nanorod arrays is found to decrease with increasing nanorod length, reaches to a minimum and then again increases with increasing length. Since nanorod arrays are subwavelength structures, the decrease in reflectance is primarily due to surface plasmon resonance. At the tip of the nanorods, the light excites the surface plasmons, which propagate along the conductor-dielectric interface. Hence, longer and consequently higher surface area nanorod arrays provide more dielectric-conductor interface for light to couple with the surface plasmons and more surface to scatter resulting in lower reflectance.
Fe–Pt Twisted Heterometallic Bicyclic Supramolecules via Multicomponent Self-Assembly

Herein, we describe a novel multicomponent self-assembly approach that has the prospect of furnishing unprecedented heterometallic bicyclic architectures with a high level of constitutional control. The methodology relies on the coordination directionality, and the stoichiometry of the individual precursor units, as well as on the difference of the coordination preference of the associated metal ions. As a proof-of-concept example, two aesthetically pleasing Fe–Pt heterometallic bicyclic metallacycles 6a and 6b, consisting of nine communicative components from four unique species, were prepared in ca. 70% isolated yields and fully characterized by multinuclear NMR, 2D NMR, electrospray ionization time-of-flight mass, and UV–vis spectroscopies. Furthermore, density functional theory based computations suggest that each of these supramolecular constructs encompasses two twisted [organo–Pt(II)←pyridine] coordination based irregular hexagons that are joined via a robust [terpyridine→Fe(II)←terpyridine] hinge.
A Return to Antitrust Populism

The trend of modern antitrust policy is consumer protection based on economic analysis. This trend has enabled meaningful protections and coherent policy. It should continue despite recent, successful populist political campaigning.
C-X-C Motif Chemokine Receptor 3 Splice Variants Differentially Activate Beta-Arrestins to Regulate Downstream Signaling Pathways.

Biased agonism, the ability of different ligands for the same receptor to selectively activate some signaling pathways while blocking others, is now an established paradigm for G protein-coupled receptor signaling. One group of receptors in which endogenous bias is critical is the chemokine system, consisting of over 50 ligands and 20 receptors that bind one another with significant promiscuity. We have previously demonstrated that ligands for the same receptor can cause biased signaling responses. The goal of this study was to identify mechanisms that could underlie biased signaling between different receptor splice variants. The C-X-C motif chemokine receptor 3 (CXCR3) has two splice variants, CXCR3A and CXCR3B, which differ by 51 amino acids at its N-terminus. Consistent with an earlier study, we found that C-X-C motif chemokine ligands 4, 9, 10, and 11 all activated G αi at CXCR3A, while at CXCR3B these ligands demonstrated no measurable G αi or G αs activity. β-arrestin (βarr) was recruited at a reduced level to CXCR3B relative to CXCR3A, which was also associated with differences in βarr2 conformation. βarr2 recruitment to CXCR3A was attenuated by both G protein receptor kinase (GRK) 2/3 and GRK5/6 knockdown, while only GRK2/3 knockdown blunted recruitment to CXCR3B. Extracellular regulated kinase 1/2 phosphorylation downstream from CXCR3A and CXCR3B was increased and decreased, respectively, by βarr1/2 knockout. The splice variants also differentially activated transcriptional reporters. These findings demonstrate that differential splicing of CXCR3 results in biased responses associated with distinct patterns of βarr conformation and recruitment. Differential splicing may serve as a common mechanism for generating biased signaling and provides insights into how chemokine receptor signaling can be modulated post-transcriptionally.
A zero-carbon supply chain model: minimising levelised cost of onsite renewable generation

ABSTRACTThis paper develops a linear optimisation model to investigate whether it is feasible to operate a net-zero-carbon supply chain network via 100% of onsite wind and solar generation. In particular, this work determines the technology, location and size of renewable generating units in an integrated production–transportation system with the goal of minimising the levelised cost of renewable energy. Numerical experiments show that it is technically feasible and economically viable to realise a zero-carbon supply chain operation provided the local facility possesses a medium wind speed and the installation cost of photovoltaics drops to $2 per watt.
Defining the factors that affect solute permeation of gap junction channels

This review focuses on the biophysical properties and structure of the pore and vestibule of homotypic gap junction channels as they relate to channel permeability and selectivity. Gap junction channels are unique in their sole role to connect the cytoplasm of two adjacent cells. In general, these channels are considered to be poorly selective, possess open probabilities approximating unity, and exhibit mean open times ranging from milliseconds to seconds. These properties suggest that such channels can function as delivery pathways from cell to cell for solutes that are significantly larger than monovalent ions. We have taken quantitative data from published works concerning unitary conductance, ion flux, and permeability for homotypic connexin 43 (Cx43), Cx40, Cx26, Cx50, and Cx37, and performed a comparative analysis of conductance and/or ion/solute flux versus diffusion coefficient. The analysis of monovalent cation flux portrays the pore as equivalent to an aqueous space where hydrogen bonding and weak interactions with binding sites dominate. For larger solutes, size, shape and charge are also significant components in determining the permeation rate. This article is part of a Special Issue entitled: Gap Junction Proteins edited by Jean Claude Herve.
Spontaneous periodic hypothermia in Parkinson disease with hypothalamic involvement.

An 88-year-old woman with history of atrial fibrillation, hypertension, and hypothyroidism was hospitalized for repeated episodes of hypothermia over 4 years. Initial rare episodes of mild hypothermia and confusion in winter months progressed to more frequent and severe episodes. The patient was hospitalized at least 3 times at other facilities before presenting to our hospital with recurrent daily episodes. During these episodes, her body temperature dropped spontaneously, followed by confusion, dysarthria, bradycardia, hypercarbic respiratory failure, and hypoglycemia.
Study of Trapping Phenomena in SrTiO 3 by Thermally Stimulated Techniques

Thermally stimulated current (TSC), thermally stimulated depolarization current (TSDC), and thermally stimulated luminescence (TSL) spectroscopies were combined to study trapping phenomena in undoped bulk SrTiO3 crystals. Electrical measurements were also performed and showed that the crystals are highly resistive in the dark but exhibited an unusually high photocurrent upon 400-nm illumination. Several traps were revealed in both TSC and TSDC spectra between 83 K and 450 K in such a broad temperature range and their activation energies were extrapolated from the trap positions (peaks). TSL spectra demonstrate similar characteristics comparable to TSC and TSDC spectra, though there are some differences because of different excitation and recombination mechanisms. This work reveals the presence of large number of traps in SrTiO3 single crystals, which are most likely the source of many of the interesting phenomena in SrTiO3 such as transient and persistent photoconductivity.
Pilot study of volume contracted state and hospital outcome after stroke.

Background An increasing body of research suggests that acute stroke patients who are dehydrated may have worsened functional outcomes. We sought to explore the relationship between a volume contracted state (VCS) at the time of ischemic stroke and hospital outcomes as compared with euvolemic patients. Methods We enrolled a consecutive series of ischemic stroke patients from a single academic stroke center within 12 hours from stroke onset. VCS was defined via surrogate markers (blood urea nitrogen/creatinine ratio >15 and urine specific gravity >1.010). The primary outcome was change in NIH Stroke Scale (NIHSS) score from admission to discharge. Multivariable analyses included adjustment for demographics and infarct size. Results Over an 11-month study period, 168 patients were eligible for inclusion. Of the126 with complete laboratory and MRI data, 44% were in a VCS at the time of admission. Demographics were similar in both the VCS and euvolemic groups, as were baseline NIHSS scores (6.7 vs 7.3; p = 0.63) and infarct volumes (12 vs 16 mL; p = 0.48). However, 42% of patients in a VCS demonstrated early clinical worsening, compared with 17% of the euvolemic group ( p = 0.02). A VCS remained a significant predictor of worsening NIHSS in adjusted models (odds ratio 4.34; 95% confidence interval 1.75–10.76). Conclusions Acute stroke patients in a VCS demonstrate worse short-term outcomes compared to euvolemic patients, independent of infarct size. Results suggest an opportunity to explore current hydration practices.

On the Problem of Parameter Identification in Perspective Systems and Its Application to Motion Estimation Problems in Computer Vision

We consider the problem of motion and shape estimation of a moving textured surface with the aid of a monocular camera. We show that the estimation problem reduces to a specific parameter estimation of a perspective dynamical system. In this paper we analyze a planar textured surface undergoing a rigid flow and an affine flow. These two cases have been analysed for perspective and orthographic projection. The main result of this paper is to identify what parameters or function of parameters are identifiable.
Improvement of Calorimetric Accuracy of DTA by Precision Sample Packing

A precision sample loading device for differential thermal analysis is developed that readily allows reduction in variations in technique and previously unaccounted heat losses. The device forms cylindrical samples of uniform size with closely controlled packing densities in which the thermocouple occupies a central position. An envelope of loosely packed porous granular aluminum oxide supports the sample in the center of a metal thermal well. Transmission of heat from the thermal head to the sample is adequate to provide a low base line deviation, while dissipation of the heat of reaction to the thermal head is restricted through a medium which is constant in its thermal properties. An exchange column for reactions involving a gaseous phase is provided which allows easy entrance or exit of reaction products.
The effect of cyclic AMP on anaerobic growth of Escherichia coli.

Adenosine 3′,5′-cyclic phosphate (cyclic AMP) stimulated a cyclic AMP-deficient mutant strain of Escherichia coli to grow anaerobically on glucose in a minimal medium and in media supplemented with nitrate or casein hydrolysate. Cyclic AMP was found to stimulate the production of the formic hydrogenlyase system in this mutant strain, but had no effect on its ability to carry out anaerobic reductions of nitrate or nitrite. It was also observed that CO2 stimulated the anaerobic growth of the mutant in the absence of cyclic AMP.
Directional Solidification of Cd1-xZnxTe at High Gravity

Cd0.96Zn0.04Te was directionally solidified by the gradient freeze technique in a furnace mounted on Clarkson’s centrifuge, at accelerations of 1, 2, 3, 4, and 5 times earth’s gravity g. The concentration of tellurium inclusions decreased markedly with increasing acceleration during solidification. The polycrystallinity of the initial portion of the ingots increased as the acceleration during solidification was increased from 3 g to 5 g. The maximum grain size and minimum infrared transmission were at 2 g. The dislocation density was unaffected by centrifugation. The axial concentration profile of zinc appears to have been unaffected by centrifugation, although the scatter in the data is large. The radial variation in zinc concentration was a maximum at 2 g and increased down the ingot.
Incomplete bladder emptying after the tension-free vaginal tape procedure, necessitating release of the mesh. A report of three cases.

Background The Tension Free Vaginal Tape (TVT) (Ethicon, Inc., Somerville, New Jersey) procedure is a minimally invasive surgical treatment for stress urinary incontinence. Urinary retention is a potential complication that may require release of the tape. Cases In three cases, prolonged urinary retention occurred after the TVT procedure. Two of the three cases were performed in conjunction with anterior repair. All three patients required surgical release of the tape, which was located at the urethrovesical junction rather than midurethra. All three patients remained stress continent after tape release. One patient developed urge incontinence. Conclusion Excessive tension, as well as tape migration toward the urethrovesical junction, may be the cause of prolonged urinary retention after the TVT procedure. Surgical release of the tape is an effective management approach to this complication.
Superheavy Nuclei to Hypernuclei: A Tribute to Walter Greiner

In nuclear physics, superheavy and hypernuclei are two of the most important fields of research. The prediction of islands of superheavy elements (Z = 114, N = 184, 196 and Z = 164, N = 318) in late sixties by the Frankfurt school played a key role in extending the periodic table of elements up to atomic number 118. Similarly, the demonstration that nuclear matter can be compressed 510 times of its original volume by nuclear shock waves, produced during heavy ion collision, led to the production of singleand double-lambda hypernuclei, as well as anti-matter nuclei. Recent observation of antihypertriton—comprising an antiproton, an antineutron, and an antilambda hyperon, by the STAR collaboration has now made it possible to envision a 3-dimensional nuclear chart of hypernuclei. My own interest in superheavy and hypernuclei was shaped from my first meeting with Walter Greiner at the International Conference on Atomic and Nuclear clusters held at Santorini, Greece in 1993. I will present a brief summary of these exciting developments, including some of our own work. Professor Greiner’s vision, enthusiasm, and encouragement touched many lives and I was one of those privileged ones.
Response increase of antenna-coupled nanothermocouples by thermal insulation

The authors present a 2.5-fold increase in the open-circuit voltage response of antenna-coupled nanothermocouples (ACNTCs) by thermally insulating them from the SiO2/Si substrate using an oxide membrane suspended over a cavity formed from the Si substrate. Polarization-dependent measurements are presented and compared to simulation results. The thermal response of the ACNTCs increases 2.5-fold when they are thermally insulated from the substrate by the cavity. The authors also show that the polarization-dependent response, and hence the polarization ratio, depends on the depth of the cavity.The authors present a 2.5-fold increase in the open-circuit voltage response of antenna-coupled nanothermocouples (ACNTCs) by thermally insulating them from the SiO2/Si substrate using an oxide membrane suspended over a cavity formed from the Si substrate.

Treatment of Prosthetic Joint Infection: Established Patient Relationships May Impact Medical Decision-Making.

BACKGROUND Choosing the intervention for prosthetic joint infections, whether debridement, antibiotics, and implant retention (DAIR), or explant and antibiotic spacer placement, is multifactorial. One characteristic that may influence this decision is a previously established relationship with the patient. We hypothesized that patients receiving their arthroplasty at an outside institution and presenting with infection would be more likely to undergo removal of their implant without an attempt at DAIR compared to patients who underwent primary arthroplasty at the investigating institution. METHODS The institutional database was queried for primary total hip and knee arthroplasty infections. Manual review of medical records was performed, excluding patients who did not meet the Musculoskeletal Infection Society definition of infection. Patient demographics, medical comorbidities, presenting infection characteristics, and surgical intervention were collected. Multivariable analysis was performed to determine the independent predictors of treatment. RESULTS A total of 270 patients were included for analysis. McPherson score (P < .001) and duration of symptoms (P < .001) were associated with subsequent treatment. Additionally, when controlling for age, gender, symptom duration category, procedure, McPherson score, and American Society of Anesthesiologists category, patients with index procedures at outside hospitals were more likely to undergo implant removal (odds ratio, 36.30; 95% confidence interval, 8.16-161.51; P < .001). CONCLUSION Patients receiving their primary arthroplasty at an outside hospital and presenting with infection are more likely to undergo removal of hardware as their initial treatment. To avoid treatment bias, institutional protocols should be implemented to guide the shared decision-making process.

Folklore, Legends, and Sexuality Education

Folklore is the unofficial culture of a group, the means by which information and attitudes are transmitted and interpreted within the group. There are many folk beliefs and contemporary legends that relate very directly to issues around sexuality, including pregnancy prevention and disease transmission. Through analyzing folklore, sexuality educators can learn a number of ways to improve their practice. By encouraging students to bring folk beliefs and contemporary legends to the classroom, sexuality educators can deal directly with students' deeply held misunderstandings or fears that otherwise might go unaddressed. This paper examines specific examples of what sexuality educators can learn from folklore and makes recommendations for use of this material in educational settings.
The islets of Langerhans continue to reveal their secrets.

Pancreatic islets, which are critical for glucose homeostasis, are endocrine microorgans embedded in the exocrine pancreas; their location has often limited studying their function. In 2019, advances in islet biology were achieved with new technologies extending findings from several decades ago and with conceptual advances built on findings from other fields.
Ultra-high birefringence and highly nonlinear dispersion compensating square photonic crystal fiber for fiber optic transmission systems: Design and analysis

In this paper, we propose an ultra-high birefringence index guiding square photonic crystal fiber (PCF) with large nonlinearity. Finite element method based software COMSOL Multiphysics is utilized to characterize the PCF guiding properties. The proposed fiber exhibits ultrahigh birefringence of 4.375×10-2 and high value of nonlinear coefficient of 91.25 W-1Km−1at excitation wavelength 1550nm by using single diameter circular air holes. In addition, fiber properties are compared with some recent PCFs to validate the proposed design. Pitch variation is also considered by taking into account the fabrication issue. The proposed fiber is a promising candidate for fiber optic transmission systems to compensate the effect of dispersion, as well as sensing applications, and super continuum generation.
Application of behavioral network in prevention and control of HIV transmission in population of men who have sex with men

In recent years,the spread of HIV infection in MSM (men who have sex with men) has drawn more and more attention in China.Whether can we control the spread of HIV infection among MSM population has important impact on the prevention and control of AIDS in China.Because of social discrimination and the tacit nature of MSM,the coverage of risk behavior intervention in MSM population is low,and HIV detection is poorly accepted and of low accessibility.Social network theory is to study the impact of individual behavior on the social network and the characteristics of the whole network by forming a network from individual to individual with their behaviors.The prevention and control of HIV infection in MSM based on behavior of network theory is discussed in this article. Key words: HIV; Behavioral network; Prevention; Control; Men who have sex with men
Personal Jurisdiction and Fifth Amendment Due Process Revisited

This draft chapter addresses the contested role of U.S. courts in adjudicating disputes with foreign elements. As a matter of domestic law, the Due Process Clauses in the U.S. Constitution constrain the scope of adjudicatory jurisdiction that legislatures can confer on State and federal courts. The Fourth Restatement restates the U.S. law of personal jurisdiction in civil proceedings as requiring that “sufficient contacts” exist between the defendant and the forum, “and that the exercise of jurisdiction be reasonable.” These criteria limit the reach of U.S. courts’ personal jurisdiction. The chapter explores these limits and Congress’s ability to extend them. It also revisits the history and jurisprudence of Fifth Amendment due process limits on personal jurisdiction, considering the Anti-Terrorism Clarification Act of 2018 (ATCA) and the Promoting Security and Justice for Victims of Terrorism Act of 2019 (PSJVTA).

Systematic review of anterior congenital cephaloceles: open vs endoscopic repair

BACKGROUND Anterior cephaloceles are rare congenital malformations that have historically been corrected via open approaches. Although the advent of endoscopic endonasal surgery has provided a minimally invasive and theoretically less morbid approach to the anterior skull base, whether endoscopic approaches provide superior treatment outcomes to open techniques has yet to be elucidated. The objective of this study was to systematically review the available literature regarding presentation and outcomes of open vs endoscopic repair of congenital anterior cephaloceles. METHODS A systematic review of the PubMed, Embase, CINAHL, and Cochrane databases was performed on January 15, 2020, to identify studies from the past 50 years reporting cases of congenital anterior cephaloceles. Data on gender, age at operation, imaging modality, cephalocele location, operative approach, and intra- and postoperative complications were collected. RESULTS Nonduplicated data (153 articles) consisted of 781 patients with congenital anterior encephaloceles. Surgical outcomes were reported in 349 patients (222 open approaches, 127 endoscopic approaches), with an average age of 4.6 years. There was a 1.3:1 male-to-female ratio. Clinical presentation included nasal obstruction (n = 154), hypertelorism (n = 106), and cleft lip/palate (n = 100). Defects were classified as sincipital (n = 479) or basal (n = 257), with 45 patients broadly classified as anterior. The number of complications experienced per operation was 0.13 for endoscopic and 0.44 for open approaches (p < 0.0001). Mortality was significantly lower for the endoscopic group compared with patients treated with open surgery (0.008 vs 0.05, p < 0.05). CONCLUSION Endoscopic repair of congenital anterior cephaloceles resulted in decreased postoperative complications and mortality compared with open approaches. ©2020 ARSAAOA, LLC.
Use of therapeutic plasma exchange for pediatric neurological diseases

Therapeutic plasma exchange is used to treat neurological diseases in the pediatric population. Since its first use in pediatric patients with hepatic coma in the form of manual whole blood exchange, therapeutic plasma exchange has been increasingly used to treat these disorders of the nervous system. This expansion is a result of improved techniques and apheresis instruments suitable for small children, as well as the recognition of its applicability to many diseases in the pediatric population. This review provides a historical overview of the use of therapeutic apheresis in children and highlights the most common applications for therapeutic plasma exchange to treat neurological disorders in children.
Green Roofs in Willamette Valley Ecoregions

This chapter covers case studies of four conservation sites and nine green roofs located in the Willamette Valley ecoregions of western Oregon. The region is geographically complex with multiple ecoregions including prairies, rocky outcrops, oak woodlands, mixed woodlands, forests, wetlands, and riparian habitats. Historically, grasslands were widespread in the valley, and these were intermixed with oak and conifer woodlands from Portland to Eugene. Less than 1% of the native prairie habitat remains intact. Precipitation averages 800–950 mm annually in the valley, and the region experiences warm to hot and dry summers and long wet winters, with infrequent snow. Much of the precipitation takes place from October through May. Although green roofs were introduced into the valley since early 2000, much of the vegetation on the over 500 green roofs in the Portland metro region has apparently not been intended to mitigate the displacement of native ecosystems by building construction. However, the nine ecoregional green roof case studies in this chapter demonstrate how 69 species of vegetation native to the Willamette Valley ecoregions can be employed on green roofs.
An Acoustic Resonator with Electromechanical Coupling of 16% and Low TCF at 5.4 GHz

In this paper, an acoustic resonator with frequency > 5 GHz is designed, implemented, and measured with electromechanical coupling exceeding 15% and low temperature dependence compared to conventional Lamb-wave resonators. The acoustic resonator is optimized for the S4 mode Lamb waves in a bi-morph composed of Lithium Niobate and Silicon Dioxide. The resonator optimization is based on adjusting the thickness of different materials in the bimorph to maximize the coupling and minimize temperature dependence simultaneously. The achieved specifications are adequate for 5G sub-6 GHz frequency band n46 in addition to Wi-Fi new bands between 5 and 6 GHz.
Quantitative Analysis of Contactin-Associated Protein and Voltage-Gated Sodium Channel Isoform 1.6 following Experimental Diffuse Traumatic Brain Injury

QUANTITATIVE ANALYSIS OF CONTACTIN-ASSOCIATED PROTEIN AND VOLTAGE-GATED SODIUM CHANNEL ISOFORM 1.6 FOLLOWING EXPERIMENTAL DIFFUSE TRAUMATIC BRAIN INJURY By Daniel James Gardiner, B.S. A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science at Virginia Commonwealth University. Virginia Commonwealth University, 2011 Major Director: Christina R Marmarou, Ph.D., Assistant Professor Department of Neurosurgery, Department of Physiology & Biophysics Traumatic axonal injury (TAI) contributes to the mortality and morbidity following diffuse traumatic brain injury (TBI). Previous work has shown that following TBI, alterations in the molecular domains of axons result in TAI. It is currently posited that injury induced ionic flux is responsible for activating deleterious proteolytic cascades, resulting in altered distributions of axonal components. However, the underlying mechanism of this progressive pathology remains elusive. This study further explores the hypothesis that altered molecular domains contributes to the progressive intra-axonal changes that characterize TAI. Using a rodent model of impact acceleration TBI we examined the expression of nodal and paranodal domains of myelinated axons in brainstem over a 24 h period post-injury. Western blot analysis was utilized to quantify changes in protein levels of Nav1.6, a prominent component at the node of Ranvier, and Caspr, a constituent of the paranodal tripartite complex. Here we report that diffuse TBI causes an up-regulation of Nav1.6 and a down-regulation of Caspr over a 24 h timecourse post-injury. The results of this study support that alterations in the molecular components of the domains of injured axons contribute to the cellular mechanism of TAI and thus provides novel data in the field of TBI research.
