Exploring the Equivalence of Factor Structure in a Measure of Depression Between Black and White Women: Measurement Issues in Comparative Research:

Although equivalence of measures is a fundamental requisite in comparative research, re searchers often have ignored or paid little attention to this important issue. This study employs exploratory factor analysis to evaluate the equivalence of factor structure of the short version (11 of 20 original items) of the well-known Center for Epidemiologic Studies-Depression (CES-D) Scale between Black and White women. The study used data from a nationwide probability sample that included 438 young (ages 24 to 59 years) Black females, 652 young White females, 340 older (ages 60 or older) Black females, and 764 older White females. The results revealed that the short CES-D Scale had different factor structures according to age and race.
Interocular transfer of simultaneous but not successive discriminations in the pigeon

Pigeons were trained with one eye covered on each of two types of visual discriminations. They then were tested for interocular transfer with the previously covered eye. Transfer was shown by every pigeon trained on a simultaneous discrimination, while lack of transfer was shown by thesesame pigeons when trained on a spatial conditional (successive) discrimination. As opposed to the pigeon, animals with a larger proportion of ipsilateral (uncrossed) retinal fibers (e.g., cats) do show transfer of both discrimination problems. This difference in the decussation of the optic pathways may be a critical variable in interocular transfer in vertebrates. Furthermore, these studies demonstrate that interocular transfer in the pigeon depends upon the experimental paradigm.
Inhibition of O2 Reduction on AA2024-T3 Using a Zr(IV)-Octadecyl Phosphonate Coating System

A thin-film coating consisting of Zr(IV) and octadecyl phosphonate provides inhibition of O 2 reduction for AA2024-T3. The coating procedure produces films with thicknesses approaching that of a self-assembled monolayer. Using constant-potential experiments, the current density for the O 2 reduction reaction has been shown to decrease by 2 orders of magnitude following five treatments. Auger electron spectroscopy of the coating shows that both Zr and phosphorus are present at the alloy surface following treatment. Characterization of the coating shows it to be hydrophobic, with the octadecyl chains being in a liquid-like environment.
Calculation of physiological acid-base parameters in multicompartment systems with application to human blood

A general formalism for calculating parameters describing physiological acid-base balance in single compartments is extended to multicompartment systems and demonstrated for the multicompartment example of human whole blood. Expressions for total titratable base, strong ion difference, change in total titratable base, change in strong ion difference, and change in Van Slyke standard bicarbonate are derived, giving calculated values in agreement with experimental data. The equations for multicompartment systems are found to have the same mathematical interrelationships as those for single compartments, and the relationship of the present formalism to the traditional form of the Van Slyke equation is also demonstrated. The multicompartment model brings the strong ion difference theory to the same quantitative level as the base excess method.
Shared Circuitry Developmental Signaling Cascades Regulate Both Embryonic and Adult Coronary Vasculature

Ischemic heart disease is the most common cause of heart failure and is among the leading causes of mortality worldwide. Therapies used for the treatment of this disease aim to restore blood flow to severely narrowed or occluded coronary arteries by either catheter-based or surgical means. Although these strategies prove efficacious for many patients, a substantial number of individuals fail to improve following these procedures. Recently, a noninvasive strategy has been proposed, focusing on the use of endogenous growth factors that trigger the growth of new coronary arteries. Using the developing heart as a model, several groups have identified some of the key pathways that not only govern the development of the coronary vascular system but also promote the growth of the adult coronary vasculature. Here, we review the major morphological events and signaling cascades that mediate the formation of the coronary vasculature in the embryo. We further describe the mechanism by which many of these same pathways also regulate the adult coronary vasculature and their potential use in the treatment of ischemic heart disease.
Units of gas permeability constants

Gas permeability constants of polymers are generally expressed by composite units which contain Numerous combinations of various units to express each component units are used. However, permeability constants of nongaseous substances in polymer membranes are generally expressed by the units of cm2/sec, which are identical to the units of the diffusion constant. The relationship between constants in units of cm2/sec and conventional composite units for gas permeability constants is presented, and the advantage of using the units in cm2/sec to express gas permeability constants is discussed.
Psychological distress in the active duty military spine patient.

ABSTRACTDisorders of the spine are a substantial burden to the military health care system that degrades readiness in the overall force. Because treatment outcomes are affected by psychosocial factors, assessment of psychological distress is important for patients with spine complaints. The incidence of psychological distress in the unique military population is not well described. The purpose of this retrospective case–control study was to determine the rate of psychological distress and identify associated patient characteristics among many variables collected in the military health system. A consecutive cohort of active duty service members presenting to a spine specialty clinic was assessed as Normal, At Risk, or Distressed using the Distress and Risk Assessment Method. Of 74 active duty patients (63 male, 11 female), 43 (58%) had some level of psychological distress: 29 (39%) At Risk, 12 (16%) Distressed-Depressive, and 2 (3%) Distressed-Somatic. Multivariate regression analysis identified female gen...
Revision of a Total Hip Arthroplasty with a Harris-Galante Porous-Coated Acetabular Component Inserted without Cement. A Follow-up Note on the Results at Five to Twelve Years*

Fifty-seven revision total hip arthroplasties in fifty-six patients were performed with a Harris-Galante porous-coated acetabular component by one surgeon, and the patients were followed prospectively for a mean of seven years (range, five to twelve years). A trochanteric osteotomy was performed in forty hips, and a posterior approach with an extended anterior capsulectomy was used in the other seventeen. The acetabular defect was classified as segmental in seven hips, cavitary in twenty-three, and combined in twenty-one; six hips had no notable defect. A bulk allograft was used in eleven hips, and morseled cancellous-bone allograft or autogenous graft was used in thirty-four hips; twelve hips did not have bone-grafting. Both the femoral and the acetabular component were revised in forty-five hips, and only the acetabular component was revised in twelve. Thirty-nine hips (68 per cent) had a good or excellent clinical result according to the Harris hip score. The acetabular component was well fixed in the fourteen hips that had a fair result and the four hips that had a poor result. The acetabular component was considered to have migrated if there was a change in the angle of the cup of 5 degrees or more or a change in the horizontal or vertical position of the cup of more than three millimeters. Despite varying degrees of bone loss, no acetabular component had radiographic evidence of loosening at the latest follow-up examination. No component was revised and no revisions were scheduled. One hip was debrided for a late metastatic infection, but the component was well fixed and was not revised. There were no complications related to the use of screws for fixation. These mid-term results confirm the early success of acetabular revisions performed with fixation of a titanium fiber-metal-coated hemispherical component with multiple screws and no cement.
The Healing Relationship: The Architectonics of Clinical Medicine

In his devastating novel of the destructive force of human passion, the Spanish philosopher-novelist, Miguel de Unamuno y Jugo records this conversation between the painter, Abel Sanchez, and the doctor, Joaquin Monegro: The habit of giving titles to paintings is peculiar to the literati; something like the doctor’s habit of giving names to diseases they can’t cure. And whatever told you that the real purpose of medicine was to cure illnesses? What is it, then? Knowledge, a knowledge of disease. The end of all science is knowledge. I had thought it was knowledge to cure. What use otherwise of having tasted the fruits of good and evil, if not to free ourselves of the evil? And the end of art, what is it? That is its own end; it contains its purpose. It is an object of beauty and that’s enough ([6], p. 366).
Optical Spectroscopy of Surface Excitations in Molecular Crystals and Monomolecular Layers

The detection of molecules at interfaces is a problem of some interest since it is the first step in following processes of more complexity. Organic molecules on solid surfaces or at the interface between media, as for example in the Helmholtz double layer region adjacent to an electrode in an electrochemical cell, can have physical and chemical properties that are quite different from their counterparts in solution and in the bulk of the solid. If these properties could be measured then one would in principle have a probe for monitoring changing surface conditions, including the possibility of following the course of chemical reactions.
Zero Meta-material Ferroelectric Phase Shifter Embedded inside LTCC

This paper describes the design and processing of a zero meta-material phase shifter (ZMPS) embedded within a low temperature co-fired ceramics (LTCC) structure. The designed ZMPS is based on a composite right/left handed meta-material (CRLH MTM) transmission line approach. L-C networks were used to achieve zero phase shift at a specified frequency. The proposed design combines the advantages of an accurate zero phase shift using meta-material concepts and the advantages of passive components (capacitors and inductors) embedded inside LTCC to reduce device size, weight, and cost. The designed phase shifter provides an accurate 0o phase shift at 0.73 GHz with −16.7 dB return-loss and −0.31 dB insertion-loss at the center frequency. The paper also provides a comparison between BST and BZT as dielectric materials embedded inside LTCC with respect to the preparation process and shrinking effects.
Research: Pharmacists and Immunizations: A National Survey

Objectives To obtain information about pharmacists' current involvement in and willingness to provide immunization services, and to assess perceived barriers to providing immunization services. Design Cross-sectional mail survey. Setting National. Patients or Other Participants Random sample of 5,342 pharmacists from chain, independent, mass merchandiser/grocery, primary care clinic, and health maintenance organization settings. Interventions None. Main Outcome Measures Responses to survey on pharmacybased immunization services—current involvement, willingness to get involved, perceived obstacles, and patients' interest. Results Three mailings yielded a response rate of 25.3% (1,348 responses). Only 53.1% of respondents knew correctly whether their state allowed pharmacists to administer immunizations. Although a significant number of pharmacists were involved in immunization activities, such as counseling and promotion, only 2.2% and 0.9% of respondents were involved in actual administration of adult and childhood immunizations, respectively. In general, men, independents, owners/partners, and pharmacists who had attended immunizationrelated educational programs were more willing to provide immunization services than were women, chain and staff pharmacists, and educational program nonattendees. Pharmacists who had attended immunization-related educational programs also perceived pharmacist- and patient-related factors as less problematic for pharmacy-based immunization services than did nonattendees. Conclusion This survey provides a baseline measure of the nature and extent of pharmacist involvement in immunizations that can be used now and in future years. The profession can use the findings on pharmacists' willingness to provide immunization services and their perception of obstacles to such services as a basis for targeted educational and promotional programs and materials.
Optimization of 2-D Flap Geometry Using Matlab and Fun3D

This paper describes work done in the process of creating a workable system for the optimization of two-element high-lift airfoil design based on a fixed "cruise configuration" baseline. Methods were developed to define airfoil flap geometry, automatically create and run unstructured computational meshes based on this geometry, and to iteratively optimize this geometry. Validation cases are presented based on different optimization algorithms and parameters. Significant work is also presented on the attempt to characterize the design space of this problem in order to better understand the performance of different optimization routines.

Occupational vehicle-related particulate exposure and inflammatory markers in trucking industry workers.

Abstract Background Previous studies have suggested an association between particulate air pollution and cardiovascular disease, but the mechanism is still unclear. Objective We examined the association between workplace exposure to vehicle-related particles and cardiovascular disease related systemic inflammatory markers, C-reactive protein (hs-CRP), soluble intercellular adhesion molecule-1 (sICAM-1), and interleukin-6 (IL-6) in 137 trucking terminal workers (non-drivers) in the U.S. trucking industry. Methods We visited two large trucking terminals in 2009 and measured vehicle-related elemental carbon (EC), organic carbon (OC), and particulate matter with aerodynamic diameter ≤2.5 µm (PM 2.5 ), for 5 days consecutively at the main work areas. Each participant provided a blood sample and completed a health questionnaire during the sampling period. Individual workplace exposure level was calculated by 12-h time weighted moving averages based on work shift. The association between each blood marker and exposure to each pollutant during 0–12, 12–24, 24–36, and 36–48 h before the blood draw was examined by multivariable regression analyses. Results In general, OC and EC had a positive association with sICAM-1, especially for exposure periods 12–24 (lag 12-24 ) and 24–36 (lag 24-36 ) h prior to blood draw [β=54.9 (95%CI: 12.3–97.5) for lag 12-24 and β=46.5 (95%CI: 21.2–71.8) for lag 12-24 ; change in sICAM-1 (in ng/mL) corresponding to an IQR increase in OC]. A similar pattern was found for EC and PM 2.5 . We did not find an association between measured pollutants up to 48 h before blood draw and hs-CRP or IL-6. Conclusion In this group of healthy workers, short-term exposure to vehicle-related air pollutants may be associated with sICAM-1. Our findings may be dependent on the exposure period studied.
Tet-On binary systems for tissue-specific and inducible transgene expression

Tissue-specific and inducible control of transgene expression is a cornerstone of modern studies in developmental biology. Even though such control of transgene expression has been accomplished in Xenopus, no general or widely available set of transgenic lines have been produced akin to those found in mouse and zebrafish. Here, I describe the design and characterization of transgenic lines in Xenopus constituting the Tet-On binary transgene expression system comprising two components: (1) rtTA transgenic lines, i.e., lines harboring the doxycycline- (Dox-) dependent transgenic transcription factor rtTA under control of a tissue-specific promoter and (2) transgenic promoter (TRE) transgenic lines, i.e., lines harboring a gene of interest (hereafter called the transgene) under control of a promoter (TRE). In double transgenic animals, i.e., embryos or tadpoles harboring both the rtTA and TRE components, transgene expression remains off the absence of Dox. Addition of Dox to the rearing water causes a conformational change in rtTA allowing it to bind the TRE promoter and induce transgene expression. Tissue specificity of transgene expression is determined by the promoter regulating rtTA expression, and inducibility is determined by the addition of Dox to the rearing water. Deposition of rtTA and TRE transgenic lines enabling tissue-specific inducible control of transgene expression into the Xenopus stock center will provide a powerful and flexible resource for studies in developmental biology.
Taking Routers Off Their Meds: Why Assumptions Of Router Stability Are Dangerous.

In this work, we examine how an adversary in control of a BGP speaker in a transit AS can cause a victim router in an arbitrary location on the Internet to become unstable. Through experimentation with both hardware and software routers, we look at the behavior of routers under abnormal conditions and come to four conclusions. First, routers placed in certain states behave in anything but a stable manner. Second, unexpected but perfectly legal BGP messages can place routers into those states with disconcerting ease. Third, an adversary can use these messages to disrupt a victim router to which he is not directly connected. Fourth, modern best practices do little to prevent these attacks.
The Poet and His Patrons

Following a practice established with his dedication of Volpone (published 1607) to Oxford and Cambridge, The Masque of Queens (1609) to Prince Henry and his tragedy Catiline His Fall (1611) to William Herbert, the Earl of Pembroke, Jonson printed The Alchemist in 1612 with a dedicatory epistle to Lady Mary Wroth, the niece of Sir Philip Sidney. His dedication of plays to individual patrons was unusual in the period and served as another sign that he considered his plays ‘classic’ pieces worthy of the recognition accorded serious literature. It also points to his complex role in the transition from an older system of literary patronage to a new market-orientated print culture.1 No contemporary playwright did more than he to raise the literary status of drama or maintained a greater independence from the usual conditions of theatrical employment, but the absence of a royalty system made it impossible for him to earn a living from the print audience he courted so assiduously? For this reason he seems to have asked for partial payment in presentation copies like those surviving examples of Cynthia’s Revels that contain inserted tributes to William Camden and the Countess of Bedford, and (as noted in Chapter 3) he cultivated a network of patrons to whom he addressed odes, epistles and epigrams of praise.3

Higher-Energy Charge Transfer States Facilitate Charge Separation in Donor-Acceptor Molecular Dyads

We simulate subpicosecond charge separation in two donor–acceptor molecular dyads. Charge separation dynamics is described using a quantum master equation, with parameters of the dyad Hamiltonian obtained from density functional theory (DFT) and time-dependent density functional theory (TDDFT) calculations and the rate of energy dissipation estimated from Ehrenfest-TDDFT molecular dynamics simulations. We find that higher-energy charge transfer states must be included in the dyad Hamiltonian in order to obtain agreement of charge separation rates with the experimental values. Our results show that efficient and irreversible charge separation involves both coherent electron transfer from the donor excited state to higher-energy unoccupied states on the acceptor and incoherent energy dissipation that relaxes the dyad to the lowest energy charge transfer state. The role of coherence depends on the initial excited state, with electron delocalization within Hamiltonian eigenstates found to be more important th...
Receptor binding assay for the detection of paralytic shellfish poisoning toxins: comparison to the mouse bioassay and applicability under regulatory use

The receptor-binding assay (RBA) method for the detection of paralytic shellfish poisoning (PSP) toxins was evaluated for its overall performance in comparison with the mouse bioassay (MBA). An initial study to evaluate the effects of filtering shellfish extracts prior to running the RBA indicated no significant difference between filtered and unfiltered extracts on the determined saxitoxin (STX) concentrations. Next, we tested the RBA assay on 295 naturally contaminated mussel tissue samples, ranging in concentrations from 320 µg STX equiv. kg-1 to 13,000 µg STX equiv. kg-1 by MBA. An overall trend was observed with the RBA giving higher results (256 µg STX equiv. kg-1 on average) than the MBA; however, at low concentrations (< 500 µg STX equiv. kg-1) the RBA results were marginally lower. A third study was conducted using spiked mussel tissue analysed by three independent laboratories, two of which performed the RBA and one the MBA. This multi-laboratory study again showed the RBA to give higher results than the MBA; however, it also revealed that STX determination was accurate by the RBA, unlike the MBA. To optimise the assay for efficient usage under regulatory practice, three suggestions have been made: the use of an initial screening plate to separate those samples that exceed the alert level; use of rapid PSP test kits in the field and in the laboratory for screening negative samples and for early detection of toxicity; and use of an alternate commercially available porcine membrane in place of the laboratory-prepared rat membrane homogenate. The large number of samples analysed and the diversity of the tests conducted in this study further support the RBA as an affordable rapid method for STX detection that is also free of the routine sacrifice of live animals.
The research grant budget: preparation and justification in relation to the proposed research.

Although the research grant budget is usually prepared after the text of a proposal has been completed, it is nonetheless an integral part of a research grant application and must clearly reflect resources needed for the proposed project. Experienced grant applicants know that the members of the staff of the granting agency and the reviewers expect to find a clear and justifiable relation between the proposed project and the requested budget. Without such a total presentation, there is little chance that the budget will be approved as requested.
Integrating Spiritual Healing Approaches and Techniques into Psychotherapy

The institution of verbal psychotherapy, as such, is a relatively recent historical development and one that first occurred in industrialized, Western societies. The precursor of contemporary verbal psychotherapy was a model that attributed the causes and cures of psychological problems to the levels of biology and physiology. Both models replaced millenia of traditional spiritual approaches to a variety of forms of malaise.

Creating a National Nuclear Regulatory Authority

power requirements, lack of indigenous resources or environmental concerns, these countries are looking at nuclear power as a solution to their increasing energy needs. Such an undertaking will require a concerted effort by national industrial firms and several branches of government. This paper will look the various phases that encompass the development of a nuclear power program from the perspective of the human resources development. In short it will consider the following issues:
P-Body Localization of the Hrr25/Casein Kinase 1 Protein Kinase Is Required for the Completion of Meiosis.

ABSTRACT P-bodies are liquid droplet-like compartments that lack a limiting membrane and are present in many eukaryotic cells. These structures contain specific sets of proteins and mRNAs at concentrations higher than that in the surrounding environment. Although highly conserved, the normal physiological roles of these ribonucleoprotein (RNP) granules remain poorly defined. Here, we report that P-bodies are required for the efficient completion of meiosis in the budding yeast Saccharomyces cerevisiae. P-bodies were found to be present during all phases of the meiotic program and to provide protection for the Hrr25/CK1 protein kinase, a key regulator of this developmental process. A failure to associate with these RNP granules resulted in diminished levels of Hrr25 and an ensuing inability to complete meiosis. This work therefore identifies a novel function for these RNP granules and indicates how protein recruitment to these structures can have a significant impact on eukaryotic cell biology.
Disorders of Fluid and Electrolytes in Newborn Infants

Maintenance requirement for fluid and electrolytes is uniquely different in low birth weight infants. An organized monitoring system is the key to successful fluid and electrolyte therapy.
Analysis Of Neurotoxic Disease: The Acrylamide Experience

The neurotoxicologist is commonly consulted when it is suspected that exposure to a chemical substance has led to an outbreak of human neurological disease. Questions emerge for which answers must be sought by experimental investigation: Is the suspect chemical the culpable agent? What type of disorder is produced? Is it reversible, can it be treated, and what is the prognosis? This paper addresses the orderly analysis of neurotoxic disease, based on experience with a number of human neurotoxins, notably the industrial monomer acrylamide.
A FRAMEWORK FOR COMPARING SYSTEMS WITH VISUAL INTERFACES

A computer program presents its capabilities and domain of application through a user interface. With the advent of inexpensive graphics hardware, systems with visual user interfaces are proliferating. New interface technologies offer opportunities for improving the usability of programs. It is important to understand how to employ these new techniques in the design of better user interfaces. A review and comparison of visual interfaces prompted the need for a vocabulary and systematic framework to describe them. This paper presents a framework developed for describing and comparing visual user interfaces. Communication between computers and humans has often been described in linguistic terms. This paper uses the term visual language to refer to the systematic use of visual presentation methods to convey meaning to a user. The framework includes a description of the interface in terms of the elements, operators and syntax of an interface language, the rationale governing the use of visual elements, the power of the language, interface characteristics such as the interaction style and input/output device dependencies, and the domain and purpose of the application. The framework has been useful in identifying important differences between visual interfaces and has provided a vocabulary for the discussion of visual language. Elements of the framework are illustrated with examples from existing systems.
Lone-Pair-Induced Topicity Observed in Macrobicyclic Tetra-thia Lactams and Cryptands: Synthesis, Spectral Identification, and Computational Assessment

The synthesis of a rigid macrobicyclic N,S lactam L1 and a topologically favored in/in N,S cryptand L2 are reported with X-ray structure analysis, dynamic correlation NMR spectroscopy, and computational analysis. Lactam L1 exhibits two distinct rotameric conformations (plus their enantiomeric counterparts) at 25 °C, as confirmed via NMR spectroscopy and computational analysis. Coalescence of the resonances of L1 was observed at 115 °C, allowing for complete nuclei to frequency correlation. Combining computational investigations with experimental data, topological equilibria and relative energies/strain relating to the perturbation of the pore were determined. Due to the increased conformational strain of the N2S2 template, the nitrogen lone pairs in L2 elicit a unique transannular interaction, resulting in a thermodynamically favored in/in nephroidal racemate. The combination of preferred topology, steric relief, and electronic localization of L2 induces a chiral environment imparted through the amine with a computed inversion barrier of 10.3 kcal mol-1.
A Complementary Cutting Plane Approach for Nonconvex Quadratically Constrained Quadratic Programs

This paper examines the nonconvex quadratically constrained quadratic programming (QCQP) problem using a complementary cutting plane method. It is well known that a QCQP can be transformed into an equivalent rank-one constrained optimization problem. Thus, we focus on searching the optimal rank-one matrix to minimize the objective while satisfying other linear matrix constraints. However, finding a rank-one matrix is computationally complicated. A cost-driven cutting plane (CDCP) method has been developed to gradually approach the rank-one constraint. To improve computational efficiency, a complementary cutting plane approach (CCPA) combing conventional intersection cut and cost-driven cut is proposed to solve QCQPs. In this new approach, a linear constraint is generated in each iteration to tighten the searching domain for a semidefinite programming problem generated from the cost-driven cut method. We further prove that adding the intersection cut in each iteration will not exclude any rank-one solution. Numerical examples with comparative results are presented and compared to verify the effectiveness and efficiency of the proposed approach.
Iridescent Life Course: LGBTQ Aging Research and Blueprint for the Future - A Systematic Review.

Background LGBTQ* (lesbian, gay, bisexual, trans, and queer) older adults are demographically diverse and growing populations. In an earlier 25-year review of the literature on sexual orientation and aging, we identified four waves of research that addressed dispelling negative stereotypes, psychosocial adjustment to aging, identity development, and social and community-based support in the lives of LGBTQ older adults. Objectives The current review was designed to develop an evidence base for the field of LGBTQ aging as well as to assess the strengths and limitations of the existing research and to articulate a blueprint for future research. Methods Using a life course framework, we applied a systematic narrative analysis of research on LGBTQ aging. The review included 66 empirical peer-reviewed journal articles (2009-2016) focusing on LGBTQ adults aged 50 years and older, as well as age-based comparisons (50 years and older with those younger). Results A recent wave of research on the health and well-being of LGBTQ older adults was identified. Since the prior review, the field has grown rapidly. Several findings were salient, including the increas-ed application of theory (with critical theories most often used) and more varied research designs and methods. While -existing life course theory provided a structure for the investigation of the social dimensions of LGBTQ aging, it was limited in its attention to intersectionality and the psychological, behavioral, and biological work emerging in the field. There were few studies addressing the oldest in these -communities, bisexuals, gender non-binary older adults, intersex, -older adults of color, and those living in poverty. -Conclusions: The Iridescent Life Course framework highlights the interplay of light and environment, creating dynamic and fluid colors as perceived from different angles and perspectives over time. Such an approach incorporates both queering and trans-forming the life course, capturing intersectionality, fluidity over time, and the psychological, behavioral, and biological as well as social dimensions of LGBTQ aging. Work is needed that investigates trauma, differing configurations of risks and resources over the life course, inequities and opportunities in representation and capital as LGBTQ adults age, and greater attention to subgroups that remain largely invisible in existing research. More depth than breadth is imperative for the field, and multilevel, longitudinal, and global initiatives are needed.
Reversed Dickson polynomials of the (k+1)-th kind over finite fields

Abstract We discuss the properties and the permutation behavior of the reversed Dickson polynomials of the ( k + 1 ) -th kind D n , k ( 1 , x ) over finite fields. The results in this paper unify and generalize several recently discovered results on reversed Dickson polynomials over finite fields.
The Greek Voyage

During the spring semester of 2018, I took History 4497, a writing intensive course with an emphasis on European travel writing. My research focused on English travel writers of the late 16th and early 17th centuries voyaging to Greece. In my analysis, I examine the interactions early English travel writers experienced with the peoples of Greece. These interactions not only allow for an interesting first-hand insight of Greek life but provide reflections of the authors and their culture. Major themes discussed in my analysis include the anti-Greek bias, civilization versus barbarism, and non-elitist perception. I came to the conclusion that while formally-educated English travel writers’ perceptions of Greece were influenced greatly by the negative biases of their teachings, Thomas Dallam, an English organ-builder with no classical knowledge nor formal education, experienced his Greek voyage with a radically different perspective.
Microneedle-Assisted Percutaneous Transport of Magnesium Sulfate

Objective In vitro diffusion experiments were performed to assess the permeation of magnesium sulfate across pig skin. Methods The mean thickness of the dermatomed porcine skin was 648 ± 12 µm. Magnesium concentration was measured using inductively coupled plasma-optical emission spectroscopy. Transdermal flux of magnesium sulfate across MN-treated and untreated porcine skin was obtained from the slope of the steady-state linear portion of cumulative amount versus time curve. Results Statistical analysis of the results was done with Student's t-test. The transdermal flux of magnesium sulfate across microneedle-treated porcine skin was 134.19 ± 2.4 µg/cm2/h and transdermal flux across untreated porcine skin was 4.64 ± 0.05 µg/cm2/h. Confocal microscopy was used to visualize the microchannels created by a solid microneedle roller (500 µm). Conclusion From our confocal microscopy studies, it was evident that the 500 μm long microneedles disrupted the stratum corneum and created microchannels measuring 191 ± 37 µm. The increase in transdermal flux across the microneedle-treated skin was statistically significant compared to that of controls, i.e., without the application of microneedles. With the application of microneedles, the transdermal flux of magnesium permeated over 12 h was approximately 33-fold higher in comparison to passive diffusion across an intact stratum corneum.
High Temperature Turbine Design Considerations: A discussion of the major technological developments which have led to the trend of using higher temperatures in modern gas turbine aero engines from a paper first presented at an AGARD conference in September

THE effect of higher turbine inlet temperature on the performance of an aircraft gas turbine engine can be quite dramatic. It can be used to increase the exhaust velocity of a dry turbojet to providea higher specific thrust; to increase the bypass ratio of a turbofan engine to improve its propulsive efficiency; to optimize the thermodynamic cycle at a higher pressure ratio to improve its specific fuel consumption; to reduce the amount of afterburner fuel flow in an augmented turbojet to improve its specific fuel consumption, or to increase the work output of a turboshaft engine. If the thrust or power of the engine is held constant, a size, cost and/or weight reduction can result. If the size of the engine is held constant growth capability can be provided.
Prediction of Functional Limitations in Balance after Tests of Tandem Walking and Standing Balance in Older Adults.

Objective Older adults who may not complain of balance problems may nevertheless be developing subtle balance problems that may affect future functioning. This study sought to determine whether subtle problems could be predicted by standard balance testing. Methods At the geriatric medicine clinic at an academic tertiary-care center, geriatricians referred 27 people who were ambulatory without gait aids and had no apparent neurologic or musculoskeletal impairments affecting their balance or gait performance. Initially, subjects were screened with some questions about vertigo, tests of standing balance on foam with eyes closed (Romberg tests) with head still, and head nodding (pitch) and shaking (yaw) at 0.3 Hz, and tandem walking with eyes closed (TW). Approximately 2 years later, 22 subjects were available to be rescreened. Results At the second test date subjects' scores declined slightly but significantly on all three variations of the Romberg tests: with head still, head pitch, and head yaw, P ≥ 0.02, but TW did not change significantly. TW was the best predictor of balance performance; the lowest-scoring subjects at the second test used a cane, had undergone hip surgery, or were scheduled for hip surgery: sensitivity 1.0, specificity 0.84. The second-best predictor was Romberg on foam with eyes closed and head still. Conclusions The data suggest that some older adults may have subtle musculoskeletal impairments that may be indicated by simple balance tests. A finding on these tests may indicate the need for further workup for balance-related problems. These quick, inexpensive tests can be administered by ancillary staff and may add important information to the initial visit and annual follow-up visits.

In vitro fertilization outcomes after preimplantation genetic testing for chromosomal structural rearrangements comparing fluorescence in-situ hybridization, microarray comparative genomic hybridization, and next-generation sequencing.

Objective To compare in vitro fertilization (IVF) outcomes for preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) using various testing platforms. Design Retrospective cohort. Setting Large academic IVF center. Patient(s) Fifty-one balanced translocation carriers undergoing IVF with PGT-SR who completed a total of 91 cycles, including 31 fluorescence in-situ hybridization (FISH), 24 microarray comparative genomic hybridization (aCGH), and 36 next-generation sequencing (NGS) testing cycles. Intervention(s) PGT-SR. Main Outcome Measure(s) Primary outcome of live-birth rate and secondary outcomes including implantation rate, clinical loss rate, and percentages of normal or balanced, unbalanced, and aneuploid embryos detected. Result(s) There was no statistically significant difference in LBR, though there was a tendency toward a higher LBR for NGS testing (14 of 19, 73.7%) compared with FISH (8 of 18, 44.4%) and aCGH (10 of 20, 50.0%). The implantation rate was statistically significantly higher for NGS (16 of 20, 80.0%) compared with FISH (11 of 25, 44.0%) and aCGH (16 of 30, 53.3%). There was no statistically significant difference in clinical pregnancy losses. There was a lower percentage of normal or balanced embryos with FISH (12.5%) compared with aCGH (23.7%) and with NGS (20.7%). Conclusion(s) This is the first report of PGT-SR outcomes for translocation carriers directly comparing PGT-SR using FISH, aCGH, and NGS. Our findings suggest an improvement in pregnancy outcomes parallel to the advancement in technology and are reassuring for continued use of NGS for this population.
Remarkable thermoelectric performance in BaPdS2 via pudding-mold band structure, band convergence, and ultralow lattice thermal conductivity

Efficient thermoelectric materials require a rare and contraindicated combination of materials properties: large electrical conductivity, large Seebeck coefficient, and low thermal conductivity. One strategy to achieve the first two properties is via low-energy electronic bands containing both flat and dispersive parts in different regions of crystal momentum space, known as a pudding-mold band structure. Here, we illustrate that ${\mathrm{BaPdS}}_{2}$ successfully achieves the pudding-mold band structure for the valence band, contributing to a large $p$-type thermoelectric power factor, due to its anisotropic crystal structure containing zigzag chains of edge-sharing square planar ${\mathrm{PdS}}_{4}$ units; large power factor is achieved for $n$-type doping as well due to band convergence. In addition, ${\mathrm{BaPdS}}_{2}$ exhibits ultralow lattice thermal conductivity, and thus also achieves the third property, due to extremely soft and anharmonic interactions in its transverse acoustic phonon branch. We predict a remarkably large thermoelectric figure of merit, with peak values between 2 and 3 for two of the three crystallographic directions, suggesting ${\mathrm{BaPdS}}_{2}$ warrants experimental investigation.

Risk Factors for Intraoperative Bladder Perforation at the Time of Midurethral Sling Placement.

OBJECTIVE To evaluate patient-specific and perioperative factors that may be predictive of bladder perforation during midurethral sling placement. METHODS A retrospective chart review of women who underwent a midurethral sling procedure at our institution between 2013 and 2017 was completed. All cases with bladder perforation were included. Patient demographics and perioperative factors were explored for associations with perforation. Bivariate analysis was used to compare baseline characteristics between those with and without perforation. Logistic regression modeling was used to identify predictors of perforation and associations between bladder perforation and postoperative sequelae. RESULTS Four hundred and ten women had a urethral sling procedure at our institution between 2013 and 2017. Of these, 35 (9%) had evidence of bladder perforation on cystoscopy. This rate was higher for retropubic slings (15%) compared to transobturator slings (2%). Those with a perforation were younger (54 vs 61 years, P= .004) and had a lower average BMI (24.1 kg/m2 vs 26.3 kg/m2, P = .022). Other risk factors included lack of pre-existing apical prolapse (11% vs 4%, P = .012) and concomitant urethrolysis (27% vs 8%, P = .024). In multivariable analysis, age, BMI, and sling type were significantly associated with perforation. In univariate analysis, perforation was associated with postoperative lower urinary tract symptoms (OR 2.3, P = .21) and urinary tract infection within 30 days of surgery (OR 2.2, P = .047). CONCLUSIONS Intraoperative bladder perforation was associated with younger patient age and lower BMI. Additionally, bladder perforation is a risk factor for postoperative urinary tract infection and lower urinary tract symptoms.
Triple-arm androgen blockade for advanced prostate cancer: a review

Prostate cancer is estimated to be the second most common malignancy in men in the USA in 2020 and represents the second highest mortality from cancer behind lung and bronchial neoplasms. Management of advanced prostate cancer is evolving. Medical androgen deprivation therapy is currently a cornerstone of therapy for prostate cancer; however molecular mechanisms of resistance have emerged leading to castration-resistant prostate cancer that is proliferation of prostate cancer in the setting of low testosterone (< 50 ng/dl). The benefit of double androgen blockade like ADT plus abiraterone acetate or androgen receptor blockers is proven in many clinical trials; however multiple mechanisms of resistance still exist. In theory, another layer of androgen blockade will prevent, or at least slow, prostate cancer proliferation. This direction of thought has recently been explored with multiple clinical trials. In this review article, we summarize the current knowledge regarding androgen resistance, newer androgen inhibition therapies, and the implications of a triple-arm anti-androgen blockade in advanced prostate cancer.
Introduction to benign prostatic hyperplasia

Abstract This chapter introduces the epidemiology, risk factors, and pathophysiology of benign prostatic hyperplasia (BPH) in adult men. It starts by introducing the magnitude of BPH in the American population and presenting an overview of how BPH leads to bothersome lower urinary tract symptoms (LUTS) in many affected men. It then discusses the epidemiology of the condition and literature-supported risk factors. Next, our current understanding of the pathophysiological mechanisms that contribute to BPH is explored. The workup involved in making a diagnosis of BPH is briefly explained, followed by a broad discussion of treatment options, including medical and surgical options. Finally, an introduction to the relationship between BPH and diet is presented. By the end of the chapter, several key topics critical to understanding the scope of BPH are explained.

Cation Size Effects in Swelling of the Layered Zeolite Precursor MCM-22-P

The chemistry and apparent cation size effects associated with swelling of the layered precursor of zeolite MCM-22 are discussed in detail and rationalized. The swelling is achieved with a custom made solution, hexadecyltrimethylammonium hydroxide (CTMA-OH) due to combination of high pH and adsorption of the cation on the surface. Alternative swelling mixtures comprising surfactant chloride (CTMA-C1) and another base, i.e. Na or tetraalkylammonium hydroxide (alkyl = methyl, ethyl, propyl) have been tried. Swelling occurred only with the tetrapropylammonium base indicating competition between CTMA and the accompanying cation. Tetrapropylammonium cation (TPA) size appeared greater (i.e. ∼ 9 A in diameter) than the spacing between silanol groups (8.2 A) on the surface, which made it less effective in competition with the surfactant cations for electrostatic attachment to the surface.
