Bounding the mass of the graviton using gravitational wave observations of inspiralling compact binaries

If gravitation is propagated by a massive field, then the velocity of gravitational waves (gravitons) will depend upon their frequency as ${(v}_{g}{/c)}^{2}=1\ensuremath{-}(c/f{\ensuremath{\lambda}}_{g}{)}^{2}$, and the effective Newtonian potential will have a Yukawa form $\ensuremath{\propto}{r}^{\ensuremath{-}1}\mathrm{exp}(\ensuremath{-}r/{\ensuremath{\lambda}}_{g})$, where ${\ensuremath{\lambda}}_{g}{=h/m}_{g}c$ is the graviton Compton wavelength. In the case of inspiralling compact binaries, gravitational waves emitted at low frequency early in the inspiral will travel slightly slower than those emitted at high frequency later, resulting in an offset in the relative arrival times at a detector. This modifies the phase evolution of the observed inspiral gravitational waveform, similar to that caused by post-Newtonian corrections to quadrupole phasing. Matched filtering of the waveforms could bound such frequency-dependent variations in propagation speed, and thereby bound the graviton mass. The bound depends on the mass of the source and on noise characteristics of the detector, but is independent of the distance to the source, except for weak cosmological redshift effects. For observations of stellar-mass compact inspiral using ground-based interferometers of the LIGO-VIRGO type, the bound on ${\ensuremath{\lambda}}_{g}$ could be of the order of $6\ifmmode\times\else\texttimes\fi{}{10}^{12}$ km, about double that from solar-system tests of Yukawa modifications of Newtonian gravity. For observations of massive black hole binary inspiral at cosmological distances using the proposed Laser Interferometer Space Antenna (LISA), the bound could be as large as $6\ifmmode\times\else\texttimes\fi{}{10}^{16}$ km. This is three orders of magnitude weaker than model-dependent bounds from galactic cluster dynamics.
Prognostic factors for stage III epithelial ovarian cancer: a Gynecologic Oncology Group Study.

PURPOSE Conflicting results on prognostic factors for advanced epithelial ovarian cancer (EOC) have been reported because of small sample size and heterogeneity of study population. The purpose of this study was to identify factors predictive of poor prognosis in a similarly treated population of women with advanced EOC. PATIENTS AND METHODS A retrospective review of demographic, pathologic, treatment, and outcome data from 1,895 patients with International Federation of Gynecology and Obstetrics stage III EOC who had undergone primary surgery followed by six cycles of intravenous platinum/paclitaxel was conducted. A proportional hazards model was used to assess the association of prognostic factors with progression-free survival (PFS) and overall survival (OS). RESULTS Increasing age was associated with increased risks for disease progression (HR = 1.06; 95% CI, 1.02 to 1.11 for an increase every 10 years) and death (HR = 1.12; 95% CI, 1.06 to 1.18). Mucinous or clear-cell histology was associated with a worse PFS and OS compared with serous carcinomas. Patients with performance status (PS) 1 or 2 were at an increased risk for recurrence compared with PS 0 (HR = 1.12; 95% CI, 1.01 to 1.24). Compared with patients with microscopic residual disease, patients with 0.1 to 1.0 cm and > 1.0 cm residual disease had an increased risk of recurrence (HR = 1.96; 95% CI, 1.70 to 2.26; and HR = 2.36; 95% CI, 2.04 to 2.73, respectively) and death (HR = 2.11; 95% CI, 1.78 to 2.49; P < .001; and HR = 2.47; 95% CI, 2.09 to 2.92, respectively). CONCLUSION Age, PS, tumor histology, and residual tumor volume were independent predictors of prognosis in patients with stage III EOC. These data can be used to identify patients with poor prognosis and to design future tailored randomized clinical trials.
Sensitivity and specificity of methods of classification of leprosy without use of skin-smear examination.

Une cohorte de 2664 nouveaux cas de lepre au Bangladesh, sur une periode de douze mois, a ete analysee dans le but d'obtenir des renseignements sur la sensibilite et la specificite de deux differentes methodes de classification de la lepre: paucibacillaire (PB) versus multibacillaire (MB), quand l'examen du suc dermique n'est pas pris en compte. Les deux methodes sont les suivantes: 1) une procedure basee sur le denombrement des lesions cutanees recommendee par l'Organisation Mondiale de la Sante (OMS) (<6 lesions cutanees = PB, ≥6 lesions cutanees = MB); et 2) la methode bangladaise (<10 lesiones cutanees et nerveuses = PB, ≥10 lesiones cutanees et nerveuses = MB). Selon ce dernier systeme, tout degre d'epaississement d'un nerf est considere comme lesion nerveuse. Cette etude a montre que la methode de l'OMS presentait une sensitivite de 89% et une specificite de 88% pour la detection des cas MB positifs a l'examen du suc dermique. Le systeme bangladais pour sa part etait sensible a 92% et specifique a 88.6%. La methode de l'OMS n'a pas detecte 18 cas de lepre MB positifs au test du suc dermique; la methode bangladaise n'a pas permis de classer comme MB 13 cas positifs au test du suc dermique. Plusieurs de ces cas manques (faux negatifs) presentaient des index bacteriens eleves. La systeme de classification des cas de lepre de l'OMS est simple a appliquer et presente un equilibre raisonnable entre senstivite et specificite. Cependant, il faut raconnaitre que ce nouveau systeme aura comme consequence la presence d'un nombre reduit, mais significatif, de cas MB positifs au test du suc dermique qui seront traites avec un traitement destine aux patients PB.
Developing library leaders in Ghana

This study explores various leadership approaches in the context of Ghanaian university libraries. Twenty-six senior librarians and faculty from the University of Ghana were interviewed to determine their views on leadership styles, skills, training and barriers to developing library leaders. Findings revealed that leaders can be developed through short courses, workshops, seminars and formal training. The biggest barrier to library leadership development in Ghana is attributed to shortage of funds for training. The study is limited to the University of Ghana librarians and faculty of the Department of Information Studies. Therefore, generalizing to other library staff may be overstretching the conclusions. Nevertheless, there are important lessons to be learnt by all. The study recommends the need for training to be taken seriously in Ghanaian libraries. Additionally, the Department of Information Studies which is the only training school for librarians and archivists was tasked to create specific leadership programmes in the curriculum.
Exposure to the Above the Influence antidrug advertisements and adolescent marijuana use in the United States, 2006-2008.

OBJECTIVES We examined the relationship between exposure to the Above the Influence antidrug campaign in 210 US media markets and adolescent marijuana and alcohol use from 2006 to 2008. METHODS We analyzed monthly advertising exposure (targeted rating points) data from the Office of National Drug Control Policy and drug use data from the Monitoring the Future study. We estimated multivariate logistic regression models of marijuana use for students in grades 8, 10, and 12, with controls for individual, family, and media market characteristics and year and regional fixed effects. RESULTS For eighth-grade adolescent girls, greater exposure to antidrug advertisements was associated with lower rates of past-month marijuana use (adjusted odds ratio [AOR] = 0.67; 95% confidence interval [CI] = 0.52, 0.87) and lower rates of lifetime marijuana use (AOR = 0.76; 95% CI = 0.62, 0.93), but not alcohol use (AOR = 1.00; 95% CI = 0.84, 1.19). Associations were not significant for adolescent boys or for students in grades 10 and 12. CONCLUSIONS Antidrug advertising may be an effective way to dissuade eighth-grade adolescent girls from initiating marijuana use.
Worker efficiency and job criticality consideration in virtual cellular manufacturing environments

Recently, virtual cellular manufacturing (VCM) environment and related production criteria have been the subject of research among the industrial engineers and academicians to realise the true benefits associated with it. Major thrust areas in VCM include cell formation (single resource constrained-SRC) and worker assignment and flexibility (dual resource constrained-DRC) related issues. The subject of this study is the later part i.e., DRC systems with worker flexibility and assignments. In VCM-DRC systems related research, the workers of each department were assumed to be of equal efficiency and no interdepartmental differences in efficiency existed. Further, criticality of jobs, an important empirical aspect, was not accounted for worker assignment scheme. This paper proposes a binary integer programming (BIP) formulation for worker assignments into virtual cells considering job criticality and varied worker efficiencies with three objectives namely maximising number of highly efficient workers to process critical jobs, minimising the need of cross training and minimising multi-cell assignment for workers. This approach has been applied to an existing VCM design problem and its performance has been analysed and discussed.
Mechanism of suppression of the long terminal repeat of Moloney leukemia virus in mouse embryonal carcinoma cells

Sequence-specific DNA-binding proteins that bind to the long terminal repeat (LTR) of Moloney leukemia virus in undifferentiated and differentiated mouse embryonal carcinoma (EC) cells were identified by gel retardation assay. The proteins that bind to the CCAAT box were present in both undifferentiated and differentiated EC cells. The amounts and the number of species of the proteins that bind to the enhancer and the GC-rich region were far lower in undifferentiated EC cells than in the differentiated counterparts. These proteins were supposed to be transcriptional activators. Proteins that bind upstream of the enhancer, namely, the -352 to -346 region and the -407 to -404 region, were identified. These proteins were designated the embryonic LTR-binding protein (ELP) and the LTR-binding protein, respectively. The ELP was present only in undifferentiated EC cell lines. The LTR-binding protein was detected in all cell lines tested. The mechanism of suppression of the LTR was investigated by the chloramphenicol acetyltransferase assay. The enhancer and the GC-rich region of the LTR functioned poorly in undifferentiated cells. When eight copies of ELP-binding sequences were inserted upstream of the enhancer region, expression of the chloramphenicol acetyltransferase gene was reduced about threefold in ECA2 cells. From these data, we concluded that two mechanisms, the shortage of activator proteins and the presence of a negative regulatory protein (ELP), are involved in the suppression of the LTR in undifferentiated EC cells.
Interprocess communication in the ninth edition unix system

When processes wish to communicate, they must first establish communication. The stream mechanisms introduced in the Eighth Edition Unix system,1 which have now become part of AT&T's Unix System V2, provide a flexible way for processes to conduct an already‐begun conversation with devices and with each other: an existing stream connection is named by a file descriptor, and the usual read, write, and I/O control requests apply. Processing modules may be inserted dynamically into a stream connection, so network protocols, terminal processing, and device drivers separate cleanly. However, these mechanisms, by themselves, do not provide a general way to create channels between processes.
The Successes and Failures of Professor Smith

The criterion employed to judge successes and failures has been the acceptance or nonacceptance of Smith's theory by his immediate successors. This judgement has been supplemented with a more personal one of scientific fruitfulness. He had one overwhelming and proper success--the theorem on resource allocation under competition--and several minor successes. He also had one modest success that was improper (i.e., unfortunate)--the distinction between productive and unproductive labor. Smith's most important analytical failure was the hierarchy of employments of capital. Three failures that should have been successes receive special attention: his wage theory, his rent theory, and the analysis of the division of labor. The reasons for the differing fates of these theories are examined.
Zimbabwe Performance-Based Budgeting: Concepts and Success Factors

Programme-based budgeting uses the budget as a tool for making public management more results focused. In its 2016 National Budget, the government of Zimbabwe stated that by 2018 all Ministries and departments should have implemented the Programme-Based Budgeting (PBB) System. This paper discusses the PBB concepts at the levels of theory and practice. The intention is not only to highlight the major features of the concept but also to critically examine the relevance of the system from a holistic perspective. The paper further seeks to critically outline the key success factors that are essential for the effective and successful implementation of the PBB system. Keywords : Programme-based budgeting, performance-based budgeting, efficiency, Zimbabwe
Renal amyloidosis is associated with increased mortality in hemodialysis patients.

AIM The aim of the study was to investigate the risk factors for mortality of hemodialysis (HD) patients at Baskent University Hospital, HD Center in Ankara, Turkey. METHODS We prospectively followed 203 stable HD patients for 42 months. Population characteristics (age, gender, duration of HD, causes of end stage renal disease [ESRD]) and biochemical variables were included in the study. Mortality was prospectively monitored. RESULTS Sixty-one patients died over 42 months. Cardiovascular events and infections/septicemia were the most common causes of death. The nonsurvivors had significantly lower hemoglobin (Hb), parathyroid hormone (PTH), creatinine, albumin, and prealbumin levels and higher age and higher C-reactive protein (CRP) levels. Survival curves as obtained by the Kaplan-Meier method in the groups of causes of ESRD (renal amyloidosis [RA], diabetes mellitus [DM], hypertension [HT] + atherosclerotic kidney disease [AKD], and others) showed that patients with DM and RA had the worst prognosis during the follow-up period. In the multivariate Cox proportional hazards model, RA and DM were found to be independent risk factors for death in HD patients together with high CRP and low albumin and prealbumin levels. Infection/septicemia is the leading cause of mortality in patients with DM and RA. CONCLUSION The results of this study indicate that the presence of RA and DM as underlying renal diseases are independent predictors of mortality in our HD patients along with poor nutritional status and activated inflammatory response.
The protective effect of inhaled chlorpheniramine and atropine on bronchoconstriction stimulated by airway cooling.

We examined the role of histamine release and reflex bronchoconstriction in the bronchoconstriction stimulated by airway cooling. In 8 asthmatic subjects, dose-response curves were determined to isocapnic hyperventilation of cold air 30 min after inhalation of chlorpheniramine maleate (18 mg nebulized during tidal breathing), 2 doses of atropine sulphate (3 mg and 18 mg nebulized), or placebo. Treatments were given on separate days, in random order and under double-blind conditions. The bronchial antihistamine and anticholinergic actions of chlorpheniramine were determined by the effect on histamine and methacholine dose-response curves on another 4 days. Chlorpheniramine was selective as an antagonist against histamine; it increased the mean provocation concentration of histamine to reduce the FEV1 by 20% (PC20) 14.2-fold but increased the mean PC20 methacholine only 1.85-fold. Atropine in the 3-mg dose, previously shown to increase the PC20 methacholine at least 100-fold, had no effect on heart rate or saliva output in contrast to 18 mg, which significantly reduced saliva output and increased heart rate. Chlorpheniramine caused no bronchodilation and a small 1.28-fold increase in the amount of respiratory heat exchange needed to reduce the FEV1 by 10% (PD10RHE). Atropine caused maximal bronchodilation after 3 mg and a dose-dependent increase in PD10RHE (1.16-fold increase after 3 mg and 1.32-fold increase after 18 mg atropine). The effect of chlorpheniramine and atropine 18 mg on PD10RHE was not significantly different. (ABSTRACT TRUNCATED AT 250 WORDS)
Antibiotic activity and microbial community of the temperate sponge, Haliclona sp.

Sessile marine invertebrates engage in a diverse array of beneficial interactions with bacterial symbionts. One feature of some of these relationships is the presence of bioactive natural products that can defend the holobiont from predation, competition or disease. In this study, we investigated the antimicrobial activity and microbial community of a common temperate sponge from coastal North Carolina.
Online Diagnosis and Localization of High-Resistance Connection in PMSM With Improved Fault Indicator

This paper proposes a method for online diagnosis and localization of high-resistance connection (HRC) in permanent magnet synchronous machine (PMSM) with an improved fault indicator. In the proposed method, the amplitude and initial phase angle of zero-sequence voltage component are both analyzed. Based on the analysis, the fault indicator with angle difference is defined for fault diagnosis and localization. It is shown that not only the HRC can be detected, but also the fault severity can be assessed and the faulty phases can be identified in this method. The simulation and experiment are carried out to verify the theoretical analysis. Both the results show that the proposed method can be effectively applied for online detection and identification of the HRC in the PMSM.
Ination taxes and ination subsidies: Explaining the twisted relationship between ination and output

This paper studies the nature of monetary policy with nancial intermediaries that provide loans for working capital in a cash-in-advance model with indivisible labor. Monetary policy occurs through money injections either directly to families or to nancial intermediaries. Injections to families produce an ination tax while injections directly to nancial intermediaries provide an ination subsidy that improves output, consumption, and welfare. This model helps explain why monetary policy based on growth in monetary aggregates can have ambiguous output e¤ects, why central bankers prefer interest rate rules to monetary aggregrate rules, and why estimated money demand equations tend to be unstable. JEL codes: E31, E50, E52 Keywords: Ination, output, working capital, monetary policy 1 Introduction The relationship between output and money (or ination) is not well understood. Even the data seem not to be clear about a relationship. Using long term data, McCandless and Weber [14] show that the relationship for OECD countries is that higher ination rates are correlated with higher output growth. However, when looking at Latin American countries they nd that higher ination rates are correlated with lower output growth. Econometric studies trying to nd Granger causal relationships between money and output have generated very mixed results. Sims [16] nds that money causes output but in later work (Sims [17]) nds that the Granger causal relationship pretty much disappears once interest rates are added to the VAR. The large literature on the instability of an estimated money demand equation (in which output is usually included) is further support on the complexity of the relationship. In spite of this empirical confusion, many central bankers operate as if money causes output and, speci cally, that appropriately timed money injections can
A passive UHF RFID pressure sensor tag with a 7.27 bit and 5.47pJ capacitive sensor interface

A full passive UHF pressure RFID tag is presented in this work. Special attention is paid to the novel capacitive sensor-interface and the analog FE which were designed and implemented on a low cost 0. 35µm standard CMOS technology. The characterization of the fabricated sensor interface connected to a pressure MEMS transducer shows a fully digital output with an ENOB of 7.27 bits and an FOM of 5.47pJ. The fabricated analog front-end, assembled to a matched dipole antenna, was connected to the digital core and the implemented pressure sensor. The RFID pressure sensor tag was characterized inside a PVC pressure chamber. Successful ID and pressure measurement (30kPa–120kPa) communication with a commercial RFID reader over a distance of 1.5m was achieved using the EPC Gen 2 standard. These characteristics allow the use of the proposed system in long range wireless pressure sensing and motivates the implementation of the proposed capacitive sensor interface in passive wireless sensors.
Virtual Screening and in Vitro Assay to Explore Novel Inhibitors from Black Pepper against Potential Targets of Radopholus Similis

similis, a migratory endoparasitic nematode that cause massive necrosis of plant tissues and destruction in host plants. The search for new nematode control molecules, particularly those of natural origin are of great urgency and importance. Phenylpropanoids belong to a major group of secondary metabolites produced by plants, mainly in defense response to biotic or abiotic stresses; literatures shows that chemical constituents of this family have bioactive compounds that can substitute current synthetic nematicides. But its efficacy and mode of action have not been demonstrated scientifically. In the present study, compounds from metabolic pathways of phenylpropanoid biosynthesis in black pepper (Piper nigrum L.) have been screened for nematicidal and potential target inhibiting activity towards burrowing nematode, R. similis and the mechanism of inhibition of novel targets has been studied with molecular docking. The 3D structures of phenylpropanoid biosynthesis related phytochemicals were used as ligands. Available eight novel target protein (β-1, 4, endoglucanase, calreticulin-1, xylanase, cathepsin B-like cysteine proteinase, cathepsin S- like cysteine proteinase, cytochrome c-oxidase subunit III, glutathione S-transferase and transthyretin-like protein 3 precursor) of nematode associated with parasitic lifestyles and survival were selected as target molecule. Potential binding sites on each protein surfaces were predicted and screened phenylpropanoids have been docked to modeled targets of R. similis to assess their molecular interaction, binding energy and consequently their inhibitory activity. The docking results showed that thirteen phenylpropanoids possess similar dock score and hydrogen bond interactions, compared to current inhibitors and nematicides. Screening of these compounds in an in vitro assay showed that eight among the thirteen phenylpropanoids (syringaldehyde, salicylic acid, catechol, ferulic acid, coumaric acid, caffeic acid, tannic acid and N- vanillylnonanamide) caused maximum mortality to R. similis at 200ppm. Ferulic acid at 250ppm and 500ppm reduced R. similis population in infected black pepper in green house study. Hence the compounds represent promising starting points as lead compounds of natural origin that inhibit R. simlis; this provides possibility to further exploit these compounds in nematode management. The study also helps in understanding various aspects of phenylpropanoid pathways that can be manipulated for in-situ production and enhancement of these compounds.
