Enhanced global symmetry constraints on ϵ terms

Abstract Recently it has been proposed that the physical spectrum of a vector-like gauge field theory may exhibit an enhanced global symmetry near a chiral/conformal phase transition (T. Appelquist, P.S. Rodrigues da Silva, F. Sannino, Phys. Rev. D 60 (1999) 116007). The new symmetry is related to the possibility, supported by various investigations, that a parity-doubled spectrum develops as the number of fermions N f is increased to a critical value above which it is expected that the symmetric phase is restored. We show that parity-doubling together with the associated enhanced global symmetry severely constrains the ϵ terms of the effective Lagrangian involving Goldstone bosons as well as massive spin-1 particles. We extend our analysis to underlying fermions in pseudo-real representations of the gauge group.
Integrated Behavioral Healthcare Models

The proliferation of integrated behavioral health over the past 30 years has been fostered by the development of a variety of practice models. While these models have evolved over time, the recognition of the need for, and development of, workforce development efforts has typically been slower to emerge. This chapter will describe the history and current state of models of integrated behavioral healthcare, as well as training initiatives and recommendations for key concepts to consider when selecting a practice model to implement.

Fundamentals of isoperibolic calorimetric for cold fusion experiments

Abstract The dominant heat transfer pathway for isoperibolic calorimeters is either by electromagnetic radiation or by conduction. However, the equations used to model cold fusion experiments using these two types of calorimeters are quite similar. The calorimeters used by Fleischmann and Pons (F-P) were the Dewar type with heat transfer mainly by radiation across the Dewar vacuum. Most other groups such as China Lake, CalTech, and MIT used calorimeters where the main heat transfer pathway was by conduction. The equations modeling cold fusion must include all power sources that flow into and out of the calorimeter. In many cases, however, these equations can be greatly simplified and still produce accurate results. The effect of small neglected terms can be later included as needed. The goal here will be to simplify the analysis of isoperibolic calorimetric results and yet retain a high accuracy for any excess power measurements.
Leaf anatomical responses and chemical composition of warm-season turfgrasses to increasing salinity

Abstract As population growth and demands for potable water increase, use of low-quality or effluent sources of irrigation is becoming more prevalent. Because these water sources often contain elevated levels of dissolved salts, turfgrasses must increasingly possess mechanisms for coping with salinity stress. The objectives of this research were to utilize Scanning Electron Microscopy (SEM) combined with Energy Dispersive X-ray Spectroscopy (EDS) to explore and characterize anatomical and physiological responses of four salinity-tolerant cultivars/experimental lines of warm-season turfgrass species including bermudagrass (Cynodon ssp.), zoysiagrass (Zoysia ssp.), St. Augustinegrass (Stenotaphrum secundatum), and seashore paspalum (Paspalum vaginatum) to salinity stress. Grasses were grown in the greenhouse under two levels of salinity stress (control = 2.5 and 30 dS m−1) prior to examination of adaxial and cross-sectional leaf surfaces using SEM and EDS. St. Augustinegrass leaf anatomy did not differ between control and elevated salinity. In bermudagrass, salt glands were observed at the 30 dS m−1 salinity level, however, none were detected at the 2.5 dS m−1 level. Zoysiagrass appeared to possess constitutive salt gland development, which although were present under 2.5 dS m−1 salinity, noticeably increased in density with increasing salinity. Seashore paspalum did not possess salt glands, but rather, exhibited bladder-like structures, in which EDS detected high levels of Na following salinity stress. These findings highlight differences in anatomical responses to salinity stress among warm-season turfgrass species. The information may aid breeders and physiologists in developing a more comprehensive understanding of warm-season turfgrass anatomical responses to salinity stress.
Platelet-rich plasma as a therapy for androgenic alopecia: a systematic review and meta-analysis.

Objective: The past decade has seen platelet-rich plasma (PRP) become a popular therapy around the world as a treatment for androgenetic alopecia (AGA). These systematic review and meta-analyses assess the effectiveness and adverse effects of PRP to determine the role of PRP as a treatment for AGA among the other non-surgical treatment modalities.Methods: This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and is registered under the PROSPERO ID CRD42019136329. Seven databases were searched from inception through May 2019. Meta-analyses of randomized controlled trials (RCTs) were performed to evaluate the effect of PRP treatments on hair density and hair thickness.Results: Thirty studies, including 687 patients, met our inclusion criteria. Twenty-nine studies reported beneficial results, and 24 studies reached statistical significance on a measured outcome. Ten RCTs were included. Our meta-analyses show that PRP treatment increases hair density and hair thickness.Conclusions: PRP is an autologous treatment that lacks serious adverse effects and effectively improves hair density and hair thickness in men and women with AGA. Future research should include low risk-of-bias RCTs to optimize treatment protocols, investigate variability among studies, and to obtain more data on hair thickness changes.
Formal Verification of Interoperability Between Future Network Architectures Using Alloy

The Internet is composed of many interconnected, interoperating networks. With the recent advances in Future Internet design, multiple new network architectures, especially Information-Centric Networks (ICN) have emerged. Given the ubiquity of networks based on the Internet Protocol (IP), it is likely that we will have a number of different interconnecting network domains with different architectures, including ICNs. Their interoperability is important, but at the same time difficult to prove. A formal tool can be helpful for such analysis. ICNs have a number of unique characteristics, warranting formal analysis, establishing properties that go beyond, and are different from, what have been used in the state-of-the-art because ICN operates at the level of content names rather than node addresses. We need to focus on node-to-content reachability, rather than node-to-node reachability. In this paper, we present a formal approach to model and analyze information-centric interoperability (ICI). We use Alloy Analyzer’s model finding approach to verify properties expressed as invariants for information-centric services (both pull and push-based models) including content reachability and returnability. We extend our use of Alloy to model counting, to quantitatively analyze failure and mobility properties. We present a formally-verified ICI framework that allows for seamless interoperation among a multitude of network architectures. We also report on the impact of domain types, routing policies, and binding techniques on the probability of content reachability and returnability, under failures and mobility.

Sparse reduced-rank regression for integrating omics data

The problem of assessing associations between multiple omics data including genomics and metabolomics data to identify biomarkers potentially predictive of complex diseases has garnered considerable research interest nowadays. A popular epidemiology approach is to consider an association of each of the predictors with each of the response using a univariate linear regression model, and to select predictors that meet a priori specified significance level. Although this approach is simple and intuitive, it tends to require larger sample size which is costly. It also assumes variables for each data type are independent, and thus ignores correlations that exist between variables both within each data type and across the data types. We consider a multivariate linear regression model that relates multiple predictors with multiple responses, and to identify multiple relevant predictors that are simultaneously associated with the responses. We assume the coefficient matrix of the responses on the predictors is both row-sparse and of low-rank, and propose a group Dantzig type formulation to estimate the coefficient matrix. Extensive simulations demonstrate the competitive performance of our proposed method when compared to existing methods in terms of estimation, prediction, and variable selection. We use the proposed method to integrate genomics and metabolomics data to identify genetic variants that are potentially predictive of atherosclerosis cardiovascular disease (ASCVD) beyond well-established risk factors. Our analysis shows some genetic variants that increase prediction of ASCVD beyond some well-established factors of ASCVD, and also suggest a potential utility of the identified genetic variants in explaining possible association between certain metabolites and ASCVD.
Dante, filósofo humanista

En el canto XXIX del “Paradiso”, Beatriz le explica al peregrino que el universo y los angeles fueron creados simultaneamente. Este pasaje es esencial para la comprension no solo de la ontologia, sino tambien del mensaje moral del poema y de su concepto del ser humano. Tras un recorrido por varias lecturas de dichos versos, este articulo sostiene que la ontologia de la Comedia es estrictamente hilemorfica, y que por consiguiente es incorrecto afirmar que para Dante la materia es un principio negativo, y que la trascendencia consiste en dejarla atras. Por el contrario, segun la Divina Comedia, el cuerpo con toda su sensualidad y su historicidad, con toda su humanidad, es imprescindible para la salvacion del alma
Automatic detection of ionospheric scintillation-like GNSS satellite oscillator anomaly using a machine-learning algorithm

In this paper, we propose a machine-learning-based approach to automatically detect a satellite oscillator anomaly. A major challenge is to differentiate an oscillator anomaly from ionospheric scintillation. Although both scintillation and oscillator anomalies cause phase disturbances, their underlying physics are different and, therefore, show different carrier-frequency dependency. By using triple-frequency signals, distinct features are extracted from the disturbed signals and applied to the radial basis function (RBF) support vector machine (SVM) classifier to identify an oscillator anomaly. The results show that the proposed RBF SVM displays superior performance and outperforms several other classification methods. The proposed approach is applied to an extensive GNSS database to conduct automatic satellite oscillator anomaly detection. Preliminary detection results validate the effectiveness of the proposed method. On average, one-to-three satellite oscillator anomaly events are detected daily at each receiver location.
Preoperative tendon retraction, not smoking, is a risk factor for failure with continuity after rotator cuff repair

Abstract Background Smoking is a poor prognostic factor for healing after rotator cuff repair and is associated with inferior results. We hypothesized that smokers would have higher recurrent tear rates and more postoperative myotendinous junction (MTJ) retraction in healed repairs than nonsmokers three months postoperatively. Methods Rotator cuff repairs (RCRs) were retrospectively reviewed over a 2-year period. Patients underwent magnetic resonance imaging (MRI) within 6 months prior to surgery and again at 3 months postoperatively. Seventy-nine patients were included and stratified by smokers versus nonsmokers. Baseline patient demographics, tear characteristics, and surgical factors were collected. Preoperative and postoperative MRIs were assessed to quantify the MTJ position and to establish the recurrent tear rate. Results For the total cohort (nonsmokers, n = 56; smokers, n = 23), significant differences in age, race, and traumatic onset of injury existed between groups. There were no significant differences in recurrent tear between smokers (26%) and nonsmokers (27%), but nonsmokers were more satisfied. For patients with healed RCRs (nonsmokers, n = 41; smokers, n = 17), there were significant differences in race. On univariate analysis, nonsmokers had a significantly more lateral MTJ postoperatively (P = 0.05). On multivariable regression analysis, medialized postoperative MTJ position in healed cuffs was driven only by greater preoperative rotator cuff retraction preoperatively. There were no significant differences in MTJ position based on smoking status for patients with healed RCRs. Conclusion Smoking does not appear to be an independent risk factor for postoperative MTJ retraction in healed RCRs, also known as failure in continuity. Preoperative tear size and retraction play the biggest roles in predicting postoperative MTJ position, regardless of smoking status. There are no significant differences in patient-reported outcomes for patients with healed RCRs, but nonsmokers had more satisfaction following RCR in the total cohort.

Secular Trends in Sugar-Sweetened Beverage Consumption Among Adults, Teens, and Children: The California Health Interview Survey, 2011-2018

Consumption of sugar-sweetened beverages (SSBs) contributes to adverse health outcomes and excess health care spending. To provide context for ongoing work assessing the impact of public health strategies, including SSB excise taxes, we used data from the California Health Interview Survey from 2011-2018 to estimate trends in beverage consumption among adults, teens, and children overall and by education, race/ethnicity, and family income. We found reductions in the annual prevalence and frequency of soda consumption across all age groups and heterogeneous increases in the consumption of fruit drinks among adults and children. Surveillance of beverage consumption trends will continue to strengthen and improve the ability of researchers and policy makers to effectively improve population health.
Subclinical Myocardial Injury and the Phenotype of Clinical Congestion in Patients With Heart Failure and Reduced Left Ventricular Ejection Fraction.

Abstract Background Clinical congestion is associated with adverse outcomes in patients with heart failure. The pathophysiological mediators of this association remain uncertain. Methods and Results We prospectively enrolled a cohort of patients with heart failure and reduced left ventricular ejection fraction and performed a detailed clinical examination followed on the same day by an invasive right heart catheterization and blood sampling for biomarkers. High-sensitivity troponin T and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were measured. A clinical congestion score was calculated based on jugular venous pressure (cm H20 14 = 2 points), bendopnea (0 vs 1), a third heart sound (0 vs 1), or peripheral edema (0–2). Congestion was categorized into tiers as absent (0 points), mild (1 point), or moderate to severe (≥ 2 points). We tested for associations of high-sensitivity troponin T, NT-proBNP, and elevated ventricular filling pressures with clinical congestion in both univariate and multivariable analyses. Of 153 participants, 65 (42%) had absent, 35 mild (23%), and 53 (35%) had moderate to severe clinical congestion. Congestion tier was associated with higher NT-proBNP and hs-troponin levels, and the right atrial pressure and pulmonary capillary wedge pressure (P Conclusions Clinical congestion is a phenotype in which there is a high coexistent presence of elevated ventricular filling pressures, elevated natriuretic peptide levels, and subclinical myocardial injury. An elevated troponin was associated with clinical congestion in multivariable models that adjusted for ventricular filling pressures and natriuretic peptide levels. These data strengthen the evidence base for an association of elevated troponin with clinical congestion, suggesting that subclinical myocardial injury may be an important contributor to the pathophysiology of the congested state.
Gene targeting of RhoA reveals its essential role in thymocyte development and metabolism (LYM7P.718)

RhoA GTPase is an intracellular signal transducer capable of regulating a wide range of cell functions including cytoskeleton dynamics, proliferation, and survival. In T lymphocytes, studies by using dominant negative mutant or C3 transferase expressing transgenic mice suggest that RhoA is involved in TCR signaling and related T cell functions such as polarization, migration, survival, and proliferation. To date, the physiological role of RhoA in T cell development remains unclear. In this study, we have achieved T cell-specific deletion of RhoA and found that RhoA gene disruption caused (1) a drastic decrease in the numbers of all thymocyte subsets including CD4-CD8- double negative (DN), CD4+CD8+ double positive (DP), CD4+CD8- single positive (SP), and CD4-CD8+ SP T cells, (2) an impaired β-selection at DN stage and positive selection at DP stage associated with altered pre-TCR and TCR signaling transduction, respectively, (3) a diminished thymocyte proliferation which could be due to impaired cytokinesis, (4) an increased apoptosis, and (5) an enhanced mitochondrial function as manifested by increased oxidative phosphorylation, glycolysis, mitochondrial membrane potential, mitochondrial numbers, mitochondrial DNA and ROS production. Thus, RhoA critically regulates T cell development by impacting on β-selection, positive selection, cell proliferation and survival through mediating pre-TCR signaling, TCR signaling, cytokinesis, and metabolism.

Sequence-selective DNA binding to the regulatory subunit of cAMP-dependent protein kinase.

Abstract The fluorescence of Trp-226 in the regulatory subunit of bovine type II cAMP-dependent protein kinase is unaffected by the binding of cAMP, but is quenched by the binding of 2'-dansyl-cAMP (DNS-cAMP). Up to 67% of the fluorescence of Trp-226 can be quenched by resonant energy transfer to the DNS-cAMP bound to the first site, and 96% of the fluorescence can be quenched by saturating both sites with DNS-cAMP. The observed efficiencies of energy transfer gave a distance of 16 A between Trp-226 and the DNS-cAMP bound at the first site and a distance of 12.7 A between Trp-226 and the DNS-cAMP bound at second site. The fluorescence of Trp-226 was suppressed by incubation of RII with the self-complementary octanucleotide TGACGTCA (CRE) due to binding of the oligonucleotide to RII. A detailed study of the binding equilibrium showed that each RII(cAMP)2 molecule binds 1 molecule of CRE with Kd = 80 nM. The corresponding Kd value for cAMP-depleted RII was found to be 25-fold higher. RII was also found to bind randomly selected DNA fragments with an average Kd value much higher than that of CRE. These observations show for the first time that the binding of oligonucleotide to RII is cAMP-enhanced and sequence-selective.
Hardware-based Demonstration of Time-Delay Interferometry and TDI-Ranging with Spacecraft Motion Effects

This hardware-based experimental simulation of the Laser Interferometer Space Antenna implements a real-time electronic duplication of the time-changing inter-spacecraft laser phase delays while measuring heterodyned laser fields with $\ensuremath{\mu}\text{ }\mathrm{cycle}$ phasemeters. The beat note measurements are used to verify the capabilities of theorized post-processing time-delay interferometry combinations in the proper time-scaled and time-shifted linear combinations. The experiments meet the $18\text{ }\text{ }\mathrm{pm}/\sqrt{\mathrm{Hz}}$ sensitivity goal of the Laser Interferometer Space Antenna after demonstrating the cancellation of $100\text{ }\text{ }\mathrm{Hz}/\sqrt{\mathrm{Hz}}$ laser phase noise by time-delay interferometry-ranging the time-varying arm length to an accuracy better than 2.0 m using a frequency-modulated ranging tone.
From Discovery to Delivery: Successful Systems Integration

Demands for information resources are increasing while libraries are facing decreasing budgets and lessening staffing support. Interlibrary loan and consortial services can help libraries expand access to collections. Patron-initiated borrowing systems are a current trend in libraries, but seamlessly integrating them is challenging. This article analyzes problems in patron-initiated consortial resource sharing, introducing a new generation service which combines complex library systems and allows them to work together in real-time availability: the online public access catalog (OPAC), a consortial borrowing system, an interlibrary loan system, an integrated library system, and an authentication system. The service seamlessly integrated a new discovery tool, WorldCat Local, with local, consortial, and worldwide resource sharing systems. Patron requests are automatically transferred from system to system based on the item's availability, maintaining rapid delivery.
A generic fine-grained parallel C

The parallel C compiler, a common language interface to multiple types of machines, is described. This language is based on the belief that an algorithm designed around fine-grained parallelism can be mapped relatively easily to different parallel architectures, since a large percentage of the parallelism has been identified. The compiler generates a FORTH-like machine-independent intermediate code. A machine-dependent translator resides on each machine to generate the appropriate executable code, taking advantage of the particular architectures. The goal for this project is to allow a user to run the same program on such machines as the massively parallel processor, the CRAY, the Connection Machine, and the CYBER 205, as well as serial machines such as VAXs, Macintoshes and Sun workstations. >
Theoretical investigations of I=5/2 quadrupolar spin dynamics in the sudden-passage regime

The theoretical approach utilizing bimodal Floquet theory in the quadrupolar/central-transition interaction frame, presented in an earlier article [J. D. Walls, K. H. Lim, and A. Pines, J. Chem. Phys. 116, 79 (2002)], is extended to describe the more complicated spin dynamics of I=5/2 spin systems. Rotary resonance effects occur when the strength of the radio-frequency irradiation, ω1, matches the sample spinning speed, ωr, at the conditions ω1=23nωr (n integral). At these conditions, conversions of both triple-quantum and five-quantum coherences to central-quantum coherence are observed. Between rotary resonance conditions [2n3ωr<ω1<[2(n+1)]/3ωr], five-quantum as well as triple-quantum coherences can be created from equilibrium z-magnetization via a nutation mechanism. In addition, effective transfer between five-quantum and triple-quantum coherences also is observed in between rotary resonance conditions. These effects have been investigated theoretically and verified by both numerical calculations and ...
Intracellular phosphate--water oxygen exchange measured by mass spectrometry.

Abstract To study, in vivo, potential P i –water oxygen exchange catalyzed by each of two high-affinity P i symporters of Neurospora crassa, we have developed methods for the purification of P i from whole-cell extracts and the subsequent derivatization of P i for analysis by GC–MS. We have also modified a published procedure for the preparation of 18 O-P i . However, the high background rate of transport-independent oxygen exchange, determined by monitoring the appearance of 18 O-P i in cells incubated in the presence of H 2 18 O, masks detection of any transport-dependent oxygen exchange which may occur. The rate of intracellular P i –water oxygen exchange is 4.36 nmol 18 O incorporated into P i per second per milligram of cell protein. The 18 O isotopic distribution of the intracellular P i closely resembles that predicted for random exchange of a single P i oxygen with that of water per enzymatic event. Based upon the observed isotopic enrichment, we calculate that the bulk intracellular P i pool must undergo an average of one oxygen exchange per phosphate ion about every 3 s.
Congenital ganglioglioma: report of a case with an unusual imaging appearance

A newborn presented with a cerebral ganglioglioma. This is a rare diagnosis in a neonate. The imaging appearance (hyperdense on CT, hyperintense on T1-weighted and hypointense on T2-weighted MRI) is very unusual for this type of tumor.
Effects of tyrosinase activity on the cytotoxicity of 4-S-cysteaminylphenol and N-acetyl-4-S-cysteaminylphenol in melanoma cells

The rationale for melanoma specific antitumor agents containing phenolic amines is based in part upon the ability of the enzyme tyrosinase to oxidize these prodrugs to toxic intermediates. Two phenolic amine compounds, N-acetyl-4-S-cysteaminylphenol (N-Ac-4-S-CAP) and 4-S-cysteaminylphenol (4-S-CAP), demonstrated growth inhibitory activity with a variety of melanoma cell lines and were essentially non-toxic to non-melanoma cell lines. Theophylline, an inhibitor of cyclic nucleotide phosphodiesterase, increased in situ tyrosinase activity and enhanced the antimelanoma effects of 4-S-CAP and N-Ac-4-S-CAP in pigmented melanoma cell lines. Phenylthiourea, a specific inhibitor of tyrosinase activity, partially blocked the growth inhibitory activity of N-Ac-4-S-CAP in human pigmented melanoma cells. Buthionine sulfoximine, an inhibitor of the synthesis of the cellular antioxidant glutathione, potentiated the growth inhibitory activity of N-Ac-4-S-CAP in pigmented melanoma cells.
ASYMPTOTIC ANALYSIS OF A TRANSLATING CABLE ARCH

The stability of a translating cable which stands in the shape of an arch between two supports is investigated. Asymptotic solutions for free in-plane and out-of-plane cable vibrations are derived under the assumption of small arch height. Without translation speed, the cable arch collapses under compressional loading. As translation speed is increased, however, the cable arch becomes tensioned and stable. A previous experiment confirms this prediction. The asymptotic solutions derived here show that the in-plane and out-of-plane vibration modes are stabilized in fundamentally different manners. 1. 1 NTRODUCTION The motion of a string translating between two eyelets is the archetypical problem in the dynamics of axially moving materials [l]. The translating string, commonly referred to as the moving threadline [2], has served as a useful model for textile machinery, chain and belt drives, fiber winders and magnetic tape drives. These diverse applications and others have been discussed by Wickert and Mote [3], who presented a detailed summary of current research in the vibration and stability of axially moving materials. The present investigation is concerned with the dynamic stability of a translating and sagged cable which is used to model the cable-like elements found in overhead conveyor systems, ski lifts, aerial tramways, and slack belt drives. Initial curvature creates linear coupling of longitudinal and transverse motions in the plane of the cable equilibrium. This linear in-plane motion is decoupled from the linear out-of-plane motion. Simpson [4] analyzed the free linear in-plane vibration of a translating cable using an asymptotic solution valid for cables with small sag? and level support eyelets. Later, Triantafyllou [ 51 extended the asymptotic solution to include cables having inclined supports and either small or very large sag. The numerical analysis by Perkins and Mote [6] considered complete three-dimensional cable motions and allowed arbitrary cable sag and support inclination. Due to initial cable curvature, the equilibrium cable tension increases with translation speed [4,6] and the translating cable can never experience the buckling instability of the simpler moving threadline [2]. An experimental investigation of a translating cable is included in a recent paper by Perkins and Mote [7] and confirms the theoretical findings of reference [6]. These investigations of translating cables have been concerned with the free linear in-plane and out-of-plane vibration of an elastic cable about an equilibrium which hangs between the supports under the influence of gravity. This equilibrium is termed the minimum catenary. In reference [7], a second equilibrium, referred to as the maximum cutenary, was noted: i.e., a cable which stands in the shape of an arch between the supports. Without translation speed, the maximum catenary collapses under compressional loading. The maximum catenary, however, becomes tensioned with increasing t Small sag is defined by a cable sag to span ratio of i or less.
1,3-Dipolar cycloaddition of azomethine ylide with ethene and 2-butene: a computational study

B3LYP/6-311 + G(d,p) has been used to calculate the relative energies and geometrical parameters of the respective reactants, transition states, and cycloadducts from the cycloadditions of azomethine ylide and ethene, (Z)-2-butene, and (E)-2-butene. The half-chair (envelope) transition state structures are consistent with a synchronous concerted cycloaddition mechanism.
Models of kidney concentrating mechanism: relationship between core concentrations and tube permeabilities

Abstract Using an inner medullary shunt model of the kidney concentrating mechanism, we investigate the relationship between z—salt and urea concentrations in the Central Core, and h—water, salt and urea permeabilities in the Henle's loop and the Collecting Duct. Computational results are given comparing (a) the direct problem: given h compute z, to (b) the inverse problem: given z compute h.
Polar organizers and girdling bands of microtubules are associated with γ-tubulin and act in establishment of meiotic quadripolarity in the hepatic Aneura pinguis (Bryophyta)

Meiosis in Aneura pinguis is preceded by extensive cytoplasmic preparation for quadripartitioning of the diploid sporocyte into a tetrad of haploid spores. In early prophase the four future spore domains are defined by lobing of the cytoplasm and development of a quadripolar prophase spindle focused at polar organizers (POs) centered in the lobes. Cells entering the reproductive phase become isolated and, instead of hooplike cortical microtubules, have endoplasmic microtubule systems centered on POs. These archesporial cells proliferate by mitosis before entering meiosis. In prophase of each mitosis, POs containing a distinct concentration of γ-tubulin appear de novo at tips of nuclei and initiate the bipolar spindle. Cells entering meiosis become transformed into quadrilobed sporocytes with four POs, one in each lobe. This transition is a complex process encompassing assembly of two opposite POs which subsequently disperse into intersecting bands of microtubules that form around the central nucleus. The girdling bands define the future planes of cytokinesis and the cytoplasm protrudes through the restrictive bands becoming quadrilobed. Two large POs reappear in opposite cleavage furrows. Each divides and the resulting POs migrate into the tetrahedral lobes of cytoplasm. Cones of microtubules emanating from the four POs interact to form a quadripolar microtubule system (QMS) that surrounds the nucleus in meiotic prophase. The QMS is subsequently transformed into a functionally bipolar metaphase spindle by migration of poles in pairs to opposite cleavage furrows. These findings contribute to knowledge of microtubule organization and the role of microtubules in spatial regulation of cytokinesis in plants.
Interorganizational Relationships in the Context of SMEs' B2B E-Commerce

Electronic commerce on the Internet has been discussed in literature as an interorganizational information system that can provide a strategic advantage via customer loyalty to small and medium-sized enterprises (SMEs). However, that is not always true, because many SMEs have difficulties achieving the benefits, as suggested by media and early research. This study is an empirical examination of the impact of the Internetâ€™s Web tools on the interorganizational relationships (IOR) between SMEs and their loyal customers. Data collected from 386 SMEs in North America (United States and Canada) and processed with Partial Least Square (PLS) show that the use of Web tools (i.e., the level of Web content and the level of security on the Internet) has a positive impact on the relation between cooperation and interdependence, and customer loyalty. However, the impact of the Internetâ€™s Web tools on the relation between trust and customer loyalty is different, because the use of nonsecure Web tools reduces the impact of trust on customer loyalty, and surprisingly, the use of secure Web tools doesnâ€™t increase or decrease the impact of trust on customer loyalty. The implications of the results of the study are discussed.
Fully absorbing dynamic compromise

Abstract I consider a repeated divide-the-dollar voting model with rejections leading to the implementation of the previous period's allocation (see Kalandrakis [14] ). I show that if proposals can be non-exhaustive, then equal division can be achieved as an absorbing steady state from any initial allocation given a large enough discount factor as a part of a Markov Perfect equilibrium. This result is robust to changes in voting thresholds and persistence in proposal power outside of unanimity or total persistence.
Novel application of 2-[18F]fluoro-2-deoxy-d-glucose to study plant defenses

Abstract Introduction Since its first use in humans in 1976, 2-[ 18 F]fluoro-2-deoxy-d-glucose ( 18 FDG) continues to serve as a tracer to measure tissue glucose metabolism in medical imaging. Here we demonstrate a novel use for this tracer to study glycoside biosynthesis in plants as a measure of plant response to defense induction. Methods Coupling autoradiography with radio high-performance liquid chromatography analysis of tissue extracts, we examined the combined effects of leaf wounding and treatment using the potent plant defense hormone, methyl jasmonate (MeJA), to measure tracer distribution and tracer use in secondary defense chemistry in Arabidopsis thaliana. We hypothesized that competing sinks like roots and reproductive tissues, as well as vascular architecture, would impact the induction of phenolic defenses of the plant that make use of glucose in glycoside formation by altering distribution and metabolic utilization of 18 FDG. Results Our studies showed that leaf orthostichy defined the major route of 18 FDG transport in both vegetative and reproductive plants when a single petiole was cut as the entry point for tracer introduction. However, when nonorthostichous leaves were damaged and treated with MeJA, 18 FDG was transported in its intact form to these leaves 3 h later, where it was incorporated into phenolic glycosides. Conclusions Our work demonstrates a new use for 18 FDG in plant science with insights into carbohydrate allocation that contradict conclusions of previous studies showing transport of resources away from damaged sites.
Finitary quasi-varieties

A pair (C,U) consisting of a category C with coequalizers and a functor U: C → Set is a weak quasi-variety if U has a left adjoint and U preserves and reflects regular epis. It is known that every weak quasi-variety is equivalent to a concrete quasi-variety, i.e. a category of Σ-algebras which has all free algebras and which is closed with respect to products and subalgebras. It is also known that if U preserves monic direct limits, C is equivalent to a concrete quasi-variety of Σ-algebras in which Σ contains no function symbols of infinite rank; and if U preserves all direct limits, C is equivalent to a concrete quasi-variety of Σ-algebras definable by a set of implications of the form (t1 = s1∧⋯∧tm = sm) ⇒ tm+1 = sm+1 where ti and si are Σ-terms and m is a nonnegative integer. This paper concerns several definitions of ‘finiteness’ in a category theoretic setting and some theorems on weak quasi-varieties. Two main theorems characterize those weak quasi-varieties (C, U) such that U preserves all direct limits.
Application of the Direct Memory Access paradigm to natural language interfaces to knowledge-based systems

This paper describes the use of the Direct Memory Access (DMA) paradigm in a practical natural language interface. Advantages and disadvantages of DMA in such applications are discussed. The DMA natural language interface 'DM-COMMAND' described in this paper is being used for development of a knowledge-based machine translation system at the Center for Machine Translation (CMT) at Carnegie Mellon University.
The role of intra-arterial chemotherapy as an adjuvant treatment for glioblastoma.

AbstractGlioblastoma multiforme (GBM) is an aggressive tumor with poor survival outcomes and limited treatment options. We conducted a literature review to compare the survival outcomes of intra-arterial (IA) and intravenous (IV) chemotherapy delivery for GBM. Nine studies of IA chemotherapy infusion with 301 total patients met our criteria for inclusion and three studies contained IV treatment groups for comparison (n = 230 for IA, n = 71 for IV). The studies were grouped by either using newly diagnosed or recurrent GBM patients. In the newly diagnosed group, IV chemotherapy produced a statistically higher median overall survival (MOS; 16.3 months) compared with IA treatment (14.02 months). However, the total number of adverse events in IA chemotherapy was 1.08 per patient whereas for IV it was higher at 1.54 events per patient. Our recurrent GBM group includes only patients treated with IA chemotherapy which resulted in an average MOS of 10.84 months. This group had 2.7 adverse events per patient but no...
A MUON COOLING RING WITH LITHIUM LENSES

We discuss particle tracking simulations in a storage ring with Lithium lens inserts designed for the transverse phase space cooling of muons by the ionization cooling. In a hard-edged magnetic element model, we demonstrate the equilibrium normalized transverse emittance of 0.3 mm*rad which is necessary for a Higgs Factory, a low energy mu+mu- Collider. For the 6 dimensional phase space cooling of muons, a method of using bent Lithium lenses were discussed.
Chiral gauge theories on a lattice and application to the chiral Schwinger model.

We derive a chiral gauge-invariant lattice fermion action from a chiral gauge-variant Wilson fermion action without changing its partition function. By using this formula we show that anomalous gauge theories are renormalizable in four dimensions and we investigate the chiral Schwinger model. We calculate the induced mass for the gauge boson compatible with the gauge invariance and show that this model is gauge invariant and unitary for a range of Wilson parameter r at the fermion one-loop level.
Hydrocephalus in Apert's syndrome.

Six children with Apert's syndrome were studied by means of pneumoencephalography or postmortem examination. Varying degrees of hydrocephalus were noted in all cases. It is suggested that hydrocephalus in association with this syndrome is more common than previously reported and that shunting procedures should be considered in an effort to decrease the severity of mental retardation noted in the majority of these patients.
An investigation of keystroke and stylometry traits for authenticating online test takers

The 2008 federal Higher Education Opportunity Act requires institutions of higher learning to make greater access control efforts for the purposes of assuring that students of record are those actually accessing the systems and taking exams in online courses by adopting identification technologies as they become more ubiquitous. To meet these needs, keystroke and stylometry biometrics were investigated towards developing a robust system to authenticate (verify) online test takers. Performance statistics on keystroke, stylometry, and combined keystroke-stylometry systems were obtained on data from 40 test-taking students enrolled in a university course. The best equal-error-rate performance on the keystroke system was 0.5% which is an improvement over earlier reported results on this system. The performance of the stylometry system, however, was rather poor and did not boost the performance of the keystroke system, indicating that stylometry is not suitable for text lengths of short-answer tests unless the features can be substantially improved, at least for the method employed.
Gamma Ray-Induced Embritilement of Pressure Vessel Alloys

High-energy gamma rays emitted from the core of a nuclear reactor produce displacement damage in the reactor pressure vessel (RPV). The contribution of gamma damage to RPV embrittlement has in the past been discounted. However, in certain reactor designs the gamma flux at the RPV is sufficiently large that its contribution to displacement damage can be substantial. For example, gamma rays have been implicated in the RPV embrittlement observed in the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. In the present study, mechanical property changes induced by 10-MeV electron irradiation of a model Fe alloy and an RPV alloy of interest to the HFIR were examined. Tensile specimens were irradiated with high-energy electrons to reproduce damage characteristic of the Compton recoil-electrons induced by gamma bombardment. Substantial increases in yield and ultimate stress were observed in the alloys after irradiation to doses up to 5.3x10−3 dpa at temperatures (~50°C) characteristic of the HFIR pressure vessel. These measured increases were similar to those previously obtained following neutron irradiation, despite the highly disparate nature of the damage generated during electron and neutron irradiations.
BERKELEY CMB EXPERIMENTS

This paper describes the status of four CMB cosmology experiments which are currently being developed by the Berkeley group. These include the APEXSZ and South Pole Telescope searches for clusters of galaxies using the Sunyaev-Zeldovich effect and the Polar Bear and EBEX CMB polarization anisotropy experiments. These experiments exploit new detector technologies with Superconducting TES bolometers and frequency domain output multiplexing, which has been developed at Berkeley.
PATIENT ATTITUDES ABOUT WEIGHT GAIN DURING PREGNANCY

Recently recommendations for weight gain during pregnancy have been liberalized. One hundred ninety-five pregnant patients (96 private, 99 clinic) were asked to complete a questionaire designed to elicit their attitudes about weight gain during pregnancy. “No response” is not listed below, therefore totals may be <100%. The results of this ouestionaire seem to indicate that many women and/or their doctors are still ignorant of current concepts of proper nutrition during pregnancy. the medical profession will need to place increased emphasis on education in this area.
STAT3 Acts as a Co-activator of Glucocorticoid Receptor Signaling

Interleukin-6 (IL-6) and glucocorticoids are important mediators of inflammatory and immunological responses. Glucocorticoids are known to synergistically enhance IL-6-mediated cellular responses. We now show that IL-6 also has a synergistic effect upon glucocorticoid signaling. In particular, IL-6-activated STAT3 associates with ligand-bound glucocorticoid receptor to form a transactivating/signaling complex, which can function through either an IL-6-responsive element or a glucocorticoid-responsive element. These findings reveal a new level of interaction between these two crucial signaling cascades and indicate that activated STAT3 can also act as a transcriptional co-activator without direct association with its DNA binding motif.
Arabinose (fucose) dehydrogenase from pig liver. I. Isolation and characterization.

Abstract A second arabinose (fucose) dehydrogenase has been isolated from pig liver and highly purified. This enzyme has a molecular weight of 245 000 and a pH maximum of 10 which is similar to that obtained for glucose dehydrogenase from the same source. Unlike glucose dehydrogenase, arabinose (fucose) dehydrogenase is insensitive to high ionic strenghts. This enzyme is NAD+ specific and histidine is involved in the active site.
On the Formation of “Hypercoordinated” Uranyl Complexes

Recent gas-phase experimental studies suggest the presence of hypercoordinated uranyl complexes. Coordination of acetone (Ace) to uranyl to form hypercoordinated species is examined using density functional theory (DFT) with a range of functionals and second-order perturbation theory (MP2). Complexes with up to eight acetones were studied. It is shown that no more than six acetones can bind directly to uranium and that the observed uranyl complexes are not hypercoordinated. In addition, other more exotic species involving proton transfer between acetones and species involving enol tautomers of acetone are high-energy species that are unlikely to form.
