A new multiband antenna for WLAN/cellular applications

Design and analysis of a new multiband antenna is presented. The antenna is suitable for use in handheld or other mobile devices. This antenna has a smaller size, and can be built on a double-sided printed circuit board or stamped from thin sheet metal. The antenna can also be built as an on-board antenna to reduce the manufacturing cost. The antenna presented is a combination of an inverted-F antenna, a coupled element and a branch element. As a triband antenna, the inverted-F antenna is for the low band, while the branch element is for the middle band and the coupled element for the high band. In some applications, the middle and the high bands can be combined as one band to form a dual band antenna. No additional matching network is required in this antenna design and as a result, the antenna efficiency is high. The method of moments is used for the analysis. The simulated SWR curves and the radiation patterns are presented. The antenna is best suited for the 2.4 GHz Bluetooth/WLAN and the 5 GHz (5.15-5.85 GHz) WLAN applications or the 800/900 MHz and the 1900/1800 MHz cellular applications.
Mutations in the Main Cytoplasmic Loop of the GABAA Receptor α4 and δ Subunits Have Opposite Effects on Surface Expression

We examined the role of putative trafficking sequences in two GABAA receptor subunits: α4 and δ. These subunits assemble with a β subunit to form a subtype of GABAA receptor involved in generating the “tonic” outward current. Both α4 and δ subunits contain dibasic retention motifs in homologous positions. When basic residues are mutated to alanine in the α4 subunit, surface expression of epitope-tagged δ subunits is increased. When basic residues in homologous regions of the δ subunit are mutated, however, surface expression is reduced. We focused on the mutants that had the maximal effects to increase (in α4) or reduce (in δ) surface expression. The total expression of δ subunits is significantly decreased by the δ mutation, suggesting an effect on subunit maturation. We also examined surface expression of the β2 subunit. Expression of the mutated α4 subunit resulted in increased surface expression of β2 compared with wild-type α4, indicating enhanced forward trafficking. In contrast, mutated δ resulted in decreased surface expression of β2 compared with wild-type δ and to α4 and β2 in the absence of any δ. This observation suggests that the mutated δ incorporates into multimeric receptors and reduces the overall forward trafficking of receptors. These observations indicate that the roles of trafficking motifs are complex, even when located in homologous positions in related subunits. The physiologic properties of receptors containing mutated subunits were not significantly affected, indicating that the mutations in the α4 subunit will be useful to enhance surface expression.
$sup 14$N(n,t) AND $sup 14$N(n,d) ANGULAR DISTRIBUTIONS AT 14.7 MeV.

A triple-coincidence counter telescope consisting of two proportional $\mathrm{dE}$ counters and a solid-state $E$ detector was used to study the angular distributions of tritons and deuterons for the ground-state transitions of ${\mathrm{N}}^{14}$ induced by 14.7-MeV neutrons. The relative triton-to-deuteron peak yield was found to be about 0.3. The ($n, t$) angular distribution is compared with pickup theory and with two other deuteron-transfer interactions between the ground states of ${\mathrm{N}}^{14}$ and ${\mathrm{C}}^{12}$: the ${\mathrm{N}}^{14}(\ensuremath{\alpha}, {\mathrm{Li}}^{6})$ and ${\mathrm{N}}^{14}(d, \ensuremath{\alpha})$ reactions. In these reactions the orbital angular momentum of the picked-up deuteron is principally $L=2$, with a smaller contribution from $L=0$ pickup suggested by the data. In addition, the ${\mathrm{N}}^{14}(n, d)$ angular distribution is compared with the Gaussian-cutoff pickup theory, and with the ${\mathrm{N}}^{14}(p, d)$ reaction to the ground state of the mirror nucleus ${\mathrm{N}}^{13}$. The angular distributions, absolute magnitudes, and reduced widths of the two reactions are nearly identical, as expected. Cluster-model interpretations of the ${\mathrm{N}}^{14}$ data are discussed.
Discrete Choice and the Social Multiplier

This note extends the Brock and Durlauf (2001) model of discrete choice with social interactions to a setting with multiple locations. This generalization leads to a closed-form measure of the "social multiplier" akin to that of Glaeser, Sacerdote, and Scheinkman (2003). The dynamics of this multiplier expose the relationship between the aggregate social outcome and the strength of the social multiplier.
Evaluation of a known breast cancer using an abbreviated breast MRI protocol: Correlation of imaging characteristics and pathology with lesion detection and conspicuity

Abstract Objective This study evaluates use of an abbreviated magnetic resonance imaging protocol with T2-weighted imaging in detecting biopsy-proven unifocal breast cancer. Materials and methods This is an institutional review board approved retrospective study of patients with biopsy-proven unifocal breast cancer (88% invasive; 12% in situ) undergoing magnetic resonance imaging. In three separate sessions, three breast imagers evaluated (1) T1-weighted non-contrast, post-contrast and post-contrast subtracted images, (2) T1-weighted images with clinical history and prior imaging, and (3) T1-weighted images and T2-weighted images with clinical history and prior imaging. Protocols were compared for cancer detection, reading time and lesion conspicuity. An independent breast radiologist retrospectively analyzed initial enhancement ratio of cancers and retrospectively reviewed lesion morphology and final pathology. Results All 107 cancers were identified at first protocol by at least one reader; five cancers were missed by either one or two readers. One cancer was missed by one reader at protocols two and three. Mean percentage detection for protocol one was 97.8%; protocol two, 99.4%, protocol three, 99.4%. T2-weighted images did not alter cancer detection but increased lesion conspicuity for 2/3 readers. 3/5 missed lesions were low grade cancers. Initial enhancement ratio was positively associated with increasing tumor grade ( p = 0.031) and pathology ( p = 0.002). Reader interpretation time decreased and lesion conspicuity increased as initial enhancement ratio increased. Conclusion Abbreviated magnetic resonance imaging has high rate of detection for known breast cancer and short interpretation time. T2 weighted imaging increased lesion conspicuity without altering detection rate. Initial enhancement ratio correlated with invasive disease and tumor grade.
Lanthanide-dependent regulation of methanol oxidation systems in Methylobacterium extorquens AM1 and their contribution to methanol growth

ABSTRACT Methylobacterium extorquens AM1 has two distinct types of methanol dehydrogenase (MeDH) enzymes that catalyze the oxidation of methanol to formaldehyde. MxaFI-MeDH requires pyrroloquinoline quinone (PQQ) and Ca in its active site, while XoxF-MeDH requires PQQ and lanthanides, such as Ce and La. Using MeDH mutant strains to conduct growth analysis and MeDH activity assays, we demonstrate that M. extorquens AM1 has at least one additional lanthanide-dependent methanol oxidation system contributing to methanol growth. Additionally, the abilities of different lanthanides to support growth were tested and strongly suggest that both XoxF and the unknown methanol oxidation system are able to use La, Ce, Pr, Nd, and, to some extent, Sm. Further, growth analysis using increasing La concentrations showed that maximum growth rate and yield were achieved at and above 1 μM La, while concentrations as low as 2.5 nM allowed growth at a reduced rate. Contrary to published data, we show that addition of exogenous lanthanides results in differential expression from the xox1 and mxa promoters, upregulating genes in the xox1 operon and repressing genes in the mxa operon. Using transcriptional reporter fusions, intermediate expression from both the mxa and xox1 promoters was detected when 50 to 100 nM La was added to the growth medium, suggesting that a condition may exist under which M. extorquens AM1 is able to utilize both enzymes simultaneously. Together, these results suggest that M. extorquens AM1 actively senses and responds to lanthanide availability, preferentially utilizing the lanthanide-dependent MeDHs when possible. IMPORTANCE The biological role of lanthanides is a nascent field of study with tremendous potential to impact many areas in biology. Our studies demonstrate that there is at least one additional lanthanide-dependent methanol oxidation system, distinct from the MxaFI and XoxF MeDHs, that may aid in classifying additional environmental organisms as methylotrophs. Further, our data suggest that M. extorquens AM1 has a mechanism to regulate which MeDH is transcribed, depending on the presence or absence of lanthanides. While the mechanism controlling differential regulation is not yet understood, further research into how methylotrophs obtain and use lanthanides will facilitate their cultivation in the laboratory and their use as a biomining and biorecycling strategy for recovery of these commercially valuable rare-earth elements.
Rabbit field

Rabbit Field is an infestation of inflatable rabbit-like forms, filling their display space and inviting tactile interaction. They cover much of the floor, and any other available surfaces, growing in number each night. Each rabbit is self-inflating using a simple computer fan, and can sense its internal pressure state by monitoring its fan speed. If a rabbit is squeezed, and partially deflated, the rabbits around it respond, as if out of empathy, deflating themselves. In this way, a wave of deflation ripples out from the squeezed center. By connecting an entire field of forms into a network of sensors and output media, interactions between viewer and inflatable are further displayed and amplified as deflation data is passed from one rabbit to the next. The organic feel of the forms and the rhythm of their inflation and deflation in reaction to human touch are easily anthropomorphized by the audience as simple expressions of emotion. This initiates and encourages play and exploration. This piece seeks to encourage and reward a 'tangible dialogue' between viewer and inflatables, as well as hoping to establish social connection between viewers who co-interact with the system. Rabbit forms were chosen to engage and invite inquiry. These animals also have strong cultural connotations of fertility and innocence, and are prevalent images in modern eastern and western aesthetic. Use of the unique properties of inflatable structures in architecture, art and design has a long and creative history, flirting between chic design and tacky novelty. http://www.media.mit.edu/~bcd/rabbits.

Unstructured Cartesian-Grid Methodology for Non-equilibrium Hypersonic Flows

A solution adaptive unstructured Cartesian grid approach is developed to solve thermochemical non-equilibrium hypersonic ∞ows with a two temperature model. This grid technique ofiers the convenience of automatic grid generation over 3D complex shaped hypersonic vehicles with the minimum user intervention while providing accurate higher order ∞ux calculations over other unstructured grid topologies. In order to avoid stifiness problems in the explicit chemical solver, a point implicit method is adopted to calculate the chemical reaction source terms. The AUSMPW+ scheme with MUSCL data reconstruction is adopted as a numerical scheme to avoid non-physical oscillations and the carbuncle phenomenon.
Mechanical Properties of the Body

The composition and structure of the structural components of the body, including bones, ligaments, tendons, and cartilage, are first presented. The mechanical properties of these body components begin by investigating their stress-strain relationships in the harmonic regime. Analysis is improved by modeling their nonlinear, time-dependent properties and then their time-dependent, viscoelastic properties. These models are used to understand how bones can bend under unusual conditions, and the occurrence of fractures and sports injuries, along with ways to avoid these unwanted events.
OONI : Open Observatory of Network Interference

OONI, the Open Observatory of Network Interference, is a global observation network which aims to collect high quality data using open methodologies, using Free and Open Source Software (FL/OSS) to share observations and open data about the various types, methods, and amounts of network tampering in the world. Furthermore, OONI is a human rights observation project – observation is a fundamental requirement for the advancement of knowledge and OONI aims to ensure that the tools to make such observations are freely available to all. With the belief that unfettered access to information is an intrinsic human right, OONI seeks to observe levels of surveillance, censorship, and network discrimination in order for people worldwide to have a clearer understanding of the ways in which their access to information and speech is monitored, censored or otherwise filtered. The end goal of OONI is to collect data which will show an accurate topology of network surveillance, interference and outright censorship. Through this data, it will be possible to draw conclusions about how the internet functions from any location where an OONI probe is present. This data includes which websites are censored, or which services have been tampered with, and by whom. The data also includes information about the observer and will attempt to classify the results. We use the term filternet to describe network connections that are under measurable surveillance, tampering, or subject to censorship.
Psychosocial impact of mast cell disorders: Pilot investigation of a rare and understudied disease:

Mast cell disorders are rare, chronic diseases involving unpredictable physical symptoms ranging in severity, duration, and frequency. Almost two-thirds of participants with these disorders (n = 180) experienced clinically meaningful depressive symptoms. Depressed mood was associated with somatic symptomatology, poorer quality of life, lower resilience, and indirectly with ways of coping. Newly developed measures for this population performed psychometrically well. There was no gender difference in depression but women reported greater use of several ways of coping, greater disease-related distress, poorer quality of life, and more symptoms. Results underscore the need for further research and development of effective psychosocial interventions for this population.
Extended range forecasting and the ENSO effects in the Corn Belt

Contingency tables are used to categorize monthly precipitation and surface temperature data from Historical Climatological Network (HCN) for use in the study of persistence in the Com Belt. Persistence for single month and several month periods is quantified climatologically using 102 years of data. The definition of persistence used here is how often each categoiy in a 2 X 2 contingency table stays in the same category from the observed period to the forecast period. Persistences reached as high as 50% in the warm months for cool and wet conditions over Missouri and Illinois. Cold month persistence using this method is less accurate. Warm-dry or cool-wet conditions were the most dominant and the most persistent except for the southeast part of the region in winter. Here warm-wet or cool-dry conditions were most common. Temperature persistence, staying below or above the mean, is the main contributor to the categorical persistence. Temperature persistence values reach near 70% for below mean temperatures during the summer and 65% for above mean temperatures during the winter. Precipitation persistence rarely reached the 60% level. Skill scores for these persistences were calculated as an improvement upon climatology. Skill was commonly in the 10-20% range for each of the cells and sometimes higher. Persistence skill is improved in all areas over other studies by classifying persistence based on the original climatic state.
PERKS: Software for Parameter Estimation in Reaction Kinetic Systems

Abstract To bring forth the recent developments in global dynamic optimization methods to practitioners, we present a software implementation- PERKS : Parameter Estimation in Reaction Kinetic Systems. PERKS performs parameter estimation in complex reaction-network models using a state-of-the-art branch-and-bound global dynamic optimization method. The built-in global optimization method in PERKS guarantees a best possible least-squares fit of experimental data by the kinetic model. PERKS is equipped with a graphical-user-interface (GUI) to streamline user interaction and reduce training-time on the software. Further, PERKS is designed keeping in mind the diverse background of our possible end-users. Example problems are included with the software to get practitioners started with minimal effort and limited background knowledge in optimization methods. In this paper, we introduce PERKS and discuss some of its key features.
Plasmacytoid dendritic cells and type 1 interferon promote peripheral expansion of forkhead box protein 3(+) regulatory T cells specific for the ubiquitous RNA-binding nuclear antigen La/Sjögren's syndrome (SS)-B.

RNA-binding nuclear antigens are a major class of self-antigen to which immune tolerance is lost in rheumatic diseases. Serological tolerance to one such antigen, La/Sjogren's syndrome (SS)-B (La), is controlled by CD4(+) T cells. This study investigated peripheral tolerance to human La (hLa) by tracking the fate of hLa-specific CD4(+) T cells expressing the transgenic (Tg) 3B5.8 T cell receptor (TCR) after adoptive transfer into lymphocyte-replete recipient mice expressing hLa as a neo-self-antigen. After initial antigen-specific cell division, hLa-specific donor CD4(+) T cells expressed forkhead box protein 3 (FoxP3). Donor cells retrieved from hLa Tg recipients displayed impaired proliferation and secreted interleukin (IL)-10 in vitro in response to antigenic stimulation. Transfer of highly purified FoxP3-negative donor cells demonstrated that accumulation of hLa-specific regulatory T cells (Treg ) was due primarily to expansion of small numbers of donor Treg . Depletion of recipient plasmacytoid dendritic cells (pDC), but not B cells, severely hampered the accumulation of FoxP3(+) donor Treg in hLa Tg recipients. Recipient pDC expressed tolerogenic markers and higher levels of co-stimulatory and co-inhibitory molecules than B cells. Adoptive transfer of hLa peptide-loaded pDC into mice lacking expression of hLa recapitulated the accumulation of hLa-specific Treg . Blockade of the type 1 interferon (IFN) receptor in hLa Tg recipients of hLa-specific T cells impaired FoxP3(+) donor T cell accumulation. Therefore, peripheral expansion of Treg specific for an RNA-binding nuclear antigen is mediated by antigen-presenting pDC in a type 1 IFN-dependent manner. These results reveal a regulatory function of pDC in controlling autoreactivity to RNA-binding nuclear antigens.
Cigarette Smoking and Coronary Artery Disease

As many speakers have reviewed during this conference, the pathogenesis of coronary heart disease, which includes the clinical manifestations of myo-cardial infarction, angina pectoris, and sudden death, is extremely complex and mediated by multiple mechanisms and etiologic factors (1). At least five interrelated processes are likely to contribute to the clinical manifestations of myocardial infarction: atherosclerosis, thrombosis, coronary artery spasm, cardiac arrythmia, and reduced capacity of the blood to deliver oxygen.
Management of Infertility in Klinefelter Syndrome

Klinefelter syndrome (KS) is a relatively common disorder with significant morbidity. Symptomatic adolescents with hypogonadal KS can be treated with testosterone supplementation therapy for androgen deficiency and concurrent human chorionic gonadotropin (hCG) to preserve fertility. Invasive biopsies and cryopreservation are not recommended in adolescents because they have significant negative effects and provide no advantage compared to delaying such procedures until adulthood when fertility is desired. For adults who have KS and desire fertility, the recommendation is medical therapy to optimize intratesticular testosterone, if the patient has a low serum testosterone level, followed by microdissection testicular sperm extraction (TESE) and pregnancy by intracytoplasmic sperm injection (ICSI). The management of fertility in adults with KS is well established with good pregnancy outcomes.

Tinzaparin in Problem Pregnancy (TIPP): Retrospective Analysis of Therapeutic Outcomes in High-Risk Pregnant Patients Treated with Tinzaparin.

BACKGROUND: Pregnancy represents a “physiologic” maternal thrombophilic state, with presumed evolutionary goals of ensuring secure fetal implantation, placental stability, and control of peripartum maternal bleeding. Specific pregnancy-induced maternal changes include increased activated Protein C resistance; decreased active Protein S; increased levels of vitamin K-dependent procoagulants, factor VIII, von Willebrand factor, and fibrinogen; and increased levels of plasminogen activator inhibitor (PAI-1). Superposition of pregnancy upon inherited or acquired thrombophilias may have untoward consequences for both mother and fetus. Venous thromboembolism (the leading cause of maternal morbidity and mortality in pregnancy) is five times more likely to occur in pregnant women than in nonpregnant women of similar age. Placental insufficiency and recurrent fetal loss are strongly associated with inherited and acquired thrombophilia, and antithrombotic interventions with aspirin, unfractionated heparin and low molecular weight heparins (LMWHs) have decreased maternal morbidity and improved fetal outcome. LMWHs offer decreased incidence of bleeding, heparin-induced thrombocytopenia with thrombosis (HITT), and osteoporosis, as well as predictable dosing efficacy. An industry sponsored series of roundtable discussions with US hematology and high-risk obstetrics practitioners revealed that a collective deterrent to use of tinzaparin (the most recently introduced LMWH with favorable pharmacokinetics and once-daily dosing) was the limited amount of published safety and efficacy data in this patient population. STUDY DESIGN: Fifty pregnancies in women treated with tinzaparin between January 2003, and June 2004, in American maternal/fetal medicine programs for high risk from prior pregnancy-associated VTE, presence of high risk pre-existing thrombophilias, or recurrent fetal loss are undergoing retrospective analysis for maternal and fetal outcomes; safety; and compliance with therapy. A specific identifier-blind data collection tool will capture historical and examination data and diagnostic studies that establish and follow risk as well as tabulate antithrombotic and adjunctive medication/supplement regimens. “Live birth” and “fetal loss” questionnaires will capture maternal and fetal course, complications, anesthesia and delivery decisions, and tissue pathology, as appropriate. RESULTS: Data analysis will be complete by late November 2004. In the absence of large randomized trials of efficacy and safety, such a study may provide guidelines for safe and effective use of tinzaparin in American high-risk pregnancy.
An Asymptotic Perturbation Expansion for Multiphase \varphi _2^4 \cdot

We consider the d=2 quantum field, with interaction density \( P\left( x \right) = \lambda x^4 - \frac{3} {4}x^2 . \) for λ < < 1, this model is known to have a phase transition [1], i.e. there exist at least two different field theories for a given λ. The new result we announce here is a detailed investigation of the two theories in which ⌽ is concentrated near ± (8λ)-1/2, namely the global minima of P(x). (Presumably these are the only pure states for the model.) We give a convergent expansion about the mean field approximation, which is asymptotic in powers of λ1/2. We explain these ideas in more detail.
Effects of hip abduction and adduction accuracy on post-stroke gait.

Abstract Background Gait instability often limits post-stroke function, although the mechanisms underlying this instability are not entirely clear. Our recent work has suggested that one possible factor contributing to post-stroke gait instability is a reduced ability to accurately control foot placement. The purpose of the present experiments was to investigate whether post-stroke gait function is related to the ability to accurately abduct and adduct the hip, as required for accurate foot placement. Methods 35 chronic stroke survivors and 12 age-matched controls participated in this experiment. Participants performed hip oscillation trials designed to quantify hip abduction/adduction accuracy, in which they lay supine and moved their leg through a prescribed range of motion in time with a metronome. Stroke survivors also performed overground walking trials at their self-selected speed. Findings 28 of the 35 stroke survivors had sufficient active range of motion to perform the prescribed hip oscillation task. In comparison to controls, these 28 stroke survivors were significantly less accurate at matching the abduction target, matching the adduction target, and moving in time with the metronome. Across these stroke survivors, a multiple regression revealed that only paretic hip abduction accuracy made a unique contribution to predicting paretic step width and paretic step period, metrics of gait performance. Interpretation The present results demonstrate that the ability to accurately abduct the hip is related to post-stroke gait performance, as predicted from a model-based gait stabilization strategy. Therefore, interventions designed to improve lower limb movement accuracy may hold promise for restoring post-stroke gait stability.

Correspondence Establishment in Statistical Shape Modeling: Optimization and Evaluation

Statistical shape modeling has been widely used in medical-imaging applications, where the shape and possible shape variation of an anatomic structure are derived from a set of shape instances of the structure. Shape correspondence, which aims to accurately identify corresponding landmarks across the given set of shape instances, is one of the main challenges in constructing a statistical shape model. In this chapter, we will discuss several important research topics in shape correspondence, including 1) pairwise shape correspondence, 2) groupwise shape correspondence, and 3) shape-correspondence performance evaluation. For simplicity, we focus on 2D shape correspondence in this chapter, with a brief discussion of the extensions to 3D shape correspondence at the end. Experiments on sample structures are presented to evaluate the performance of the proposed methods.
Culture and Stock Price Synchronicity: The Effects of Tightness and Individualism

In this paper, we examine the effect of culture on cross-country differences in stock price synchronicity. We focus on two cultural dimensions. The first, tightness-looseness, relates to the external constraints on investors’ behavior that helps to explain the similarity/diversity in individual behaviors within a country (Gelfand et al., Science, 2011). The second, individualism- collectivism, focuses on the internal attributes that guide investor’s behavior and reflects the degree to which people focus on their internal attributes to differentiate from others (Hofstede, 1980). Together, tightness and individualism influence the inter-personal similarity/diversity of behaviors and the tendency to think holistically/analytically, which are likely to affect stock price synchronicity. Using stock returns of 45 countries from 1990 to 2010, we find a higher stock price synchronicity in countries with a tighter and less individualistic culture. Both market-wide and firm-specific stock return variations are lower (higher) in countries that are culturally tight (loose). On the other hand, individualism just increases firm-specific variations. The marginal effect of culture on stock price synchronicity is comparable to those of previously documented determinants of stock price synchronicity, such as good government index and information opaqueness. We also find that the influence of culture on the stock price co-movement is weaker in countries that are more open to trade and more integrated with the global stock market. Taken together, our study suggests that culture is an important omitted variable in the literature that examines cross-country differences in the stock price co-movement.
Single phase ACDC converter performance improvement with AC power ripple compensation controller

The main purpose of this paper is to develop a DC voltage controller with AC power ripple compensation for single phase ACDC converter, which is served as the front-end converter for an energy storage system. Due to the single phase ACDC converter circuit topology, the AC and DC side both exist power ripple with doubled grid frequency. In conventional controller, DC voltage is controlled to be a constant value, thus the ripple current flowing into DC capacitor increases and the control of input current is also affected. A DC voltage controller with AC power ripple compensation for single phase ACDC converter is implemented to control DC voltage with voltage ripple compensation. Therefore the power of AC and DC side will be balanced. The voltage ripple is calculated by AC input power with a fully digital controller. By controlling the DC voltage with voltage ripple obtained from AC power, the ripple current flowing into DC capacitor will decrease. The test plant of this paper is a 3kW single phase ACDC converter with fully digitalized control. The experiment results are introduced to verify the control method.

Detrusor-Sphincter Dyssynergia and Detrusor Hyperreflexia Leading to Hydronephrosis During Intermittent Catheterization

AbstractTwo cases of spinal cord injury with detrusor-sphincter dyssynergia and detrusor hyperreflexia are presented. In 1 patient bilateral hydronephrosis developed between 3 and 7 months after injury while he was on intermittent catheterization. In the other patient early sphincterotomy (3½ months post-injury) was not followed by upper tract changes. Urodynamic evaluation should be done before intermittent catheterization is continued for more than 3 months after spinal cord injury. The importance of early diagnosis and appropriate management of detrusor-sphincter dyssynergia associated with detrusor hyperreflexia is discussed.
Synthetic Prosthetic Choices in Ventral Hernia Repair

The use of synthetic mesh to repair abdominal wall defects has drastically lowered the recurrence rates. The main material, polypropylene, has been the industry standard for over 40 years. Other materials such as PET and Polytetrafluoroethylene (PTFE) are also commonly used as hernia mesh. Newer products include synthetic resorbable mesh and coated mesh. With over 80 different types of mesh available, choosing the optimal mesh for a particular procedure can be overwhelming. This chapter addresses the state of the current synthetic mesh used in ventral hernia repair, including the challenging task of choosing the “best” mesh.
Physical Principles of Ultrasound

First utilized at the Naval Medical Research Institute in the late 1940s, medical ultrasound imaging has become a universal tool that has revolutionized the way modern medicine is practiced. Recognized as a relatively inexpensive and safe imaging modality, ultrasound has applications in many areas of medicine.
Trait negative affect moderates the effects of expressive versus experiential emotion suppression

Abstract Despite popularity of research on emotion suppression, the moderating effects of trait emotionality on different methods for suppressing emotion remain relatively unexamined. To address this issue, we experimentally tested suppression of emotional expression versus emotional experience on multiple emotions among individuals with varying levels of trait negative affect (NA). Participants were randomly assigned to suppress expression or experience, or to pay attention (control) during a sadness- and anxiety-inducing film clip and a subsequent 2-minute recovery period. Results revealed moderating effects of trait NA and variable effects of suppression across each emotion. There was no effect of experimental group on sadness, anxiety or cardiac responding, but participants suppressing expression showed decreased anxiety and cardiac responding associated with increased levels of trait NA compared to other groups. There were no effects of suppressing experience compared to controls for self-reported emotion or physiology. Findings suggest that individual differences in trait emotionality influence the effects of suppressing expression, that the effects of suppressing emotion may depend on the emotion suppressed, and that these forms of suppression do not constitute the same emotion regulatory process. Additional theoretical and methodological implications are discussed.
Kinetic Analyses of the Siderophore Biosynthesis Inhibitor Salicyl-AMS and Analogues as MbtA Inhibitors and Antimycobacterial Agents.

There is a paramount need for expanding the drug armamentarium to counter the growing problem of drug-resistant tuberculosis. Salicyl-AMS, an inhibitor of salicylic acid adenylation enzymes, is a first-in-class antibacterial lead compound for the development of tuberculosis drugs targeting the biosynthesis of salicylic-acid-derived siderophores. In this study, we determined the Ki of salicyl-AMS for inhibition of the salicylic acid adenylation enzyme MbtA from Mycobacterium tuberculosis (MbtAtb), designed and synthesized two new salicyl-AMS analogues to probe structure–activity relationships (SAR), and characterized these two analogues alongside salicyl-AMS and six previously reported analogues in biochemical and cell-based studies. The biochemical studies included determination of kinetic parameters (Kiapp, konapp, koff, and tR) and analysis of the mechanism of inhibition. For these studies, we optimized production and purification of recombinant MbtAtb, for which Km and kcat values were determined, and ...
Improving body function and minimizing activity limitations in pediatric leukemia survivors: The lasting impact of the Stoplight Program.

BACKGROUND After acute lymphoblastic leukemia (ALL) treatment, children can have persistent muscle weakness, range of motion limitations, and decreased function after treatment. The Stoplight Program (SLP), a proactive physical therapy intervention, was administered as the standard of care during ALL treatment to prevent and minimize these impairments. The purpose of this follow-up study was to measure body function and activity limitations in ALL survivors who completed the SLP and compare them to a pre-SLP control group, thus evaluating the longer term impact of the SLP. PROCEDURE Two cohorts of survivors of pediatric ALL ages 5 to 18 years were assessed 18 to 24 months after completing ALL treatment. Measurements included both the body coordination subtest and the strength and agility subtest of the Bruininks-Oseretsky Test of Motor Proficiency, active dorsiflexion range of motion (ADROM), and physical activity by self-report. RESULTS The control group and SLP group did not differ in size (n = 15), mean age (9 years), or time off ALL treatment (20 months). The SLP group had better scale scores for bilateral coordination (P = 0.05), running speed/agility (P < 0.01), and strength (P = 0.01). The number of survivors with 5 degrees or greater of ADROM (right) was significantly greater in the SLP group. ADROM had a positive correlation with strength/agility standard score in the combined survivor group. CONCLUSION The SLP is a proactive physical therapy intervention that continues to positively impact children after treatment. Referral to physical therapy should be the standard to optimize long-term function.

Trauma and Resilience in the Lives of Contemporary Native Americans: Reclaiming our Balance, Restoring our Wellbeing

Indigenous Peoples around the world and our allies often reflect on the many challenges that continue to confront us, the reasons behind health, economic, and social disparities, and the best ways forward to a healthy future. This book draws on theoretical, conceptual, and evidence-based scholarship as well as interviews with scholars immersed in Indigenous wellbeing, to examine contemporary issues for Native Americans. It includes reflections on resilience as well as disparities. In recent decades, there has been increasing attention on how trauma, both historical and contemporary, shapes the lives of Native Americans. Indigenous scholars urge recognition of historical trauma as a framework for understanding contemporary health and social disparities. Accordingly, this book uses a trauma-informed lens to examine Native American issues with the understanding that even when not specifically seeking to address trauma directly, it is useful to understand that trauma is a common experience that can shape many aspects of life. Scholarship on trauma and trauma-informed care is integrated with scholarship on historical trauma, providing a framework for examining contemporary issues for Native American populations. It should be considered essential reading for all human service professionals working with Native American clients, as well as a core text for Native American studies and classes on trauma or diversity more generally.
The Intergenerational Transmission of Protective Parent Responses to Historical Trauma

Parenting practices exist within developmental contexts that include individual and sociocultural determinants. Family therapists, researchers in attachment, and child maltreatment have long recognized the risk factors posed by parents’ individual trauma histories and how this trauma may impact their parenting behavior with their child. Parenting practices exist within developmental contexts that include individual and sociocultural determinants. Family therapists, researchers in attachment, and child maltreatment have long recognized the risk factors posed by parents’ individual trauma histories and how this trauma may impact their parenting behavior with their child. In this chapter, I propose that children of parents who are survivors of historical trauma such as genocide, slavery, and separation of boarding schools must include a strength-based perspective to understand parenting practices. I argue that in the face of the sustained traumas that occurred over generations of different ethnic, cultural, or religious groups, the generation of parents that the historical trauma occurred had to create effective parenting strategies to fight for their child and group’s survival. Evidence is presented of possible interacting biopsychosocial mechanisms that may contribute to the intergenerational transmission of historical trauma in parent–child relationships. Finally, I discuss the broader elements within the social context that may serve as triggers for the use of traumagenic protective parenting practices. These triggers for protective parenting practices include stereotypes and biases, traditions, policies, and norms that serve to remind – albeit invisibly – the targeted group of the original trauma and their status in the eyes of the oppressor. I conclude the chapter with a personal response to the topic and suggestions for future research.

The SP19 chronology for the South Pole Ice Core – Part 2: gas chronology, Δage, and smoothing of atmospheric records

Abstract. A new ice core drilled at the South Pole provides a 54 000-year paleoenvironmental record including the composition of the past atmosphere. This paper describes the SP19 chronology for the South Pole atmospheric gas record and complements a previous paper (Winski et al., 2019) describing the SP19 ice chronology. The gas chronology is based on a discrete methane (CH4) record with 20- to 190-year resolution. To construct the gas time scale abrupt changes in atmospheric CH4 during the glacial period and centennial CH4 variability during the Holocene were used to synchronize the South Pole gas record with analogous data from the West Antarctic Ice Sheet Divide ice core. Stratigraphic matching based on visual optimization was verified using an automated matching algorithm. The South Pole ice core recovers all expected changes in CH4 based on previous records. Smoothing of the atmospheric record due to gas transport in the firn is evident but relatively minor, despite the deep lock-in depth in the modern South Pole firn column. The new gas chronology, in combination with the existing ice age scale from Winski et al. (2019), allows a model-independent reconstruction of the gas age-ice age difference through the whole record, which will be useful for testing firn densification models.
Implementation of a Gradiometer Receive Coil for a Single-Sided FFL MPI Scanner

A single-sided MPI scanner holds a great promise for a variety of clinical applications. In such a scanner the SPIOs response to the excitation is detected by a planar receive coil on the surface of the device. Due to a single-sided geometry, differentiating a small signal on a strong excitation background becomes a challenging task and further impinges the potential sensitivity gain, thus we implemented a new planar gradiometer receive coil configuration for our MPI scanner. The preliminary results imply the improved sensitivity of the device over the traditional single coil design. Int. J. Mag. Part.

Auditory Feedback Control of Vocal Pitch in Spasmodic Dysphonia.

OBJECTIVES/HYPOTHESIS Hearing plays an important role in the maintenance of vocal control in normal individuals. In patients with spasmodic dysphonia (SD), however, the ability to maintain sustained control of phonation is impaired. The origins of SD are unknown, and it is unclear whether auditory feedback-dependent vocal control is compromised in these patients. STUDY DESIGN Prospective case-control study. METHODS We tested 15 SD patients and 11 age-matched controls. Voice recordings were performed while subjects repeated the vowel /e/ and auditory feedback of their vocal sounds was altered in real-time to introduce a pitch-shift (±2 semitones), presented back to subjects using headphones. Recordings were analyzed to determine voice changes following the pitch-shifted feedback. Results were further compared with patient demographics and subjective measures of dysphonia, including the Voice Handicap Index (VHI). RESULTS Despite considerable pitch variability and vocal breaks, SD patients exhibited significantly higher average vocal pitch compensation than control subjects. SD patients also exhibited greater variability than controls. However, there were no significant correlations between vocal compensation and patient demographics, although there was a significant inverse correlation with VHI. CONCLUSIONS In this pilot study, patients with SD exhibited increased sensitivity to altered auditory feedback during sustained phonation. These results are consistent with recent theories of SD as a disorder of sensory-motor feedback processing, and suggest possible avenues for future investigation.

Bone Marrow Aspirate Concentrate as a Reliable Adjunct in Tibiotalocalcanal Fusion: A Radiographic Modified RUST Score Analysis

Tibiotalar and subtalar arthritis requiring tibiotalocalcaneal (TTC) fusion can be technically challenging and is dependent on reliable fusion for a good clinical outcome. Initial data regarding bone marrow aspirate concentrate (BMAC) has shown promise in use as an aide in both fracture and fusion healing. The purpose of this study is to determine the outcomes in TTC fusion when utilizing BMAC as an adjunct. Twenty consecutive patients who underwent TTC fusion with BMAC adjunct between March 2013 and November 2017 were retrospectively screened for inclusion. Patients were included regardless of comorbidities or risk factors for non-union, and only excluded if they did not have a minimum of 12 months of clinical and/or radiographic chart data. Follow-up was obtained at regular intervals of 6 weeks, 3 months, 6 months and 1 year. Modified RUST scores were applied to grade bony union in a blinded fashion by two orthopedic trauma fellowship-trained surgeons and agreement was assessed via intraclass correlation coefficient (ICC). Twenty patients were screened and 12 met inclusion criteria for analysis. Majority were male (66.6%) at a mean age of 55.4 years and they were all treated via TTC fusion for a diagnosis of tibiotalar and subtalar arthritis. There were no postoperative complications and no reoperations in this cohort; no donor site morbidity was associated with BMAC. By the 3-month follow-up timepoint, all but one patient received a minimum modified RUST score of 10 indicating bony union (ICC 0.91); by the 6-month time point (ICC 0.94), all 12 patients were deemed united. BMAC as an adjunct in the setting of TTC fusion is a safe treatment option that can promote reliable, consistent bony fusion with minimal complications.
