Linear multiuser receivers in random environments

We study the signal-to-interference (SIR) performance of linear multiuser receivers in random environments, where signals from the users arrive in "random directions. " Such a random environment may arise in a DS-CDMA system with random signature sequences, or in a system with antenna diversity where the randomness is due to channel fading. Assuming that such random directions can be tracked by the receiver, the resulting SIR performance is a function of the directions and therefore also random. We study the asymptotic distribution of this random performance in the regime where both the number of users K and the number of degrees of freedom N in the system are large, but keeping their ratio fixed. Our results show that for both the decorrelator and the minimum mean-square error (MMSE) receiver, the variance of the SIR distribution decreases like 1/N, and the SIR distribution is asymptotically Gaussian. We compute closed-form expressions for the asymptotic means and variances for both receivers. Simulation results are presented to verify the accuracy of the asymptotic results for finite-sized systems.
Subcellular Redistribution of NHERF1 in Response to Dehydroepiandrosterone (DHEA) Administration in Endometrial Glands of Wistar Rats

To understand the regulation of Na(+)/H(+) exchanger regulatory factor (NHERF1) in polycystic ovarian syndrome, we studied the expression of NHERF1 in uterus of Wistar rats injected with (6 mg/kg) of dehydroepiandrosterone (DHEA) for 7 and 20 days. Immunohistochemistry analysis of NHERF1 showed a substantial shift in the intracellular localization of NHERF1 in endometrial glands and areas of luminal epithelium as early as 7 days of DHEA administration. The NHERF1 accumulated in the “Golgi apparatus area” virtually in all the glands in the 7-day protocol, and in the majority of the glands of 20-day protocol. In contrast, NHERF1 is expressed in the apical membrane and slightly in the cytoplasm of the control epithelium. The subcellular redistribution of NHERF1 could affect the sorting of proteins to the apical membrane and the organization of the apical compartment.
Statistical Matching and Imputation of Survey Data with StatMatch

Statistical matching techniques aim at integrating two or more data sources (usually data from sample surveys) referred to the same target population. In the basic statistical matching framework, there are two data sources A and B sharing a set of variables X while the variable Y is available only in A and the variable Z is observed just in B. The X variables are common to both the data sources, while the variables Y and Z are not jointly observed. The objective of statistical matching (hereafter denoted as SM) consists in investigating the relationship between Y and Z at “micro” or “macro” level (D’Orazio et al., 2006b). In the micro case the SM aims at creating a “synthetic” data source in which all the variables, X, Y and Z, are available (usually A ∪B with all the missing values filled in, or simply A filled in with the values of Z). When the objective is macro, the data sources are integrated to derive an estimate of the parameter of interest, e.g. the correlation coefficient between Y and Z or the contingency table Y × Z. A parametric approach to SM requires the explicit adoption of a model for (X,Y, Z); obviously, if the model is misspecified the results will not be reliable. The nonparametric approach is more flexible in handling complex situations (different types of variables). The two approaches can be mixed: first a parametric model is assumed and its parameters are estimated then a synthetic data set is derived through a nonparametric micro approach. In this manner the advantages of both parametric and nonparametric approach are maintained: the model is parsimonious while nonparametric techniques offer protection against model misspecification. Table 1 provides a summary of the objectives and approaches to SM (D’Orazio et al., 2008).
PHYSICOCHEMICAL CHARACTERIZATION OF CAPSTONE DEPLETED URANIUM AEROSOLS II: PARTICLE SIZE DISTRIBUTIONS AS A FUNCTION OF TIME

The Capstone Depleted Uranium (DU) Aerosol Study, which generated and characterized aerosols containing DU from perforation of armored vehicles with large-caliber DU penetrators, incorporated a sampling protocol to evaluate particle size distributions. Aerosol particle size distribution is an important parameter that influences aerosol transport and deposition processes as well as the dosimetry of the inhaled particles. These aerosols were collected on cascade impactor substrates using a pre-established time sequence following the firing event to analyze the uranium concentration and particle size of the aerosols as a function of time. The impactor substrates were analyzed using proportional counting, and the derived uranium content of each served as input to the evaluation of particle size distributions. Activity median aerodynamic diameters (AMADs) of the particle size distributions were evaluated using unimodal and bimodal models. The particle size data from the impactor measurements were quite variable. Most size distributions measured in the test based on activity had bimodal size distributions with a small particle size mode in the range of between 0.2 and 1.2 &mgr;m and a large size mode between 2 and 15 &mgr;m. In general, the evolution of particle size over time showed an overall decrease of average particle size from AMADs of 5 to 10 &mgr;m shortly after perforation to around 1 &mgr;m at the end of the 2-h sampling period. The AMADs generally decreased over time because of settling. Additionally, the median diameter of the larger size mode decreased with time. These results were used to estimate the dosimetry of inhaled DU particles.
Using Discourse Structure Improves Machine Translation Evaluation

We present experiments in using discourse structure for improving machine translation evaluation. We first design two discourse-aware similarity measures, which use all-subtree kernels to compare discourse parse trees in accordance with the Rhetorical Structure Theory. Then, we show that these measures can help improve a number of existing machine translation evaluation metrics both at the segment- and at the system-level. Rather than proposing a single new metric, we show that discourse information is complementary to the state-of-the-art evaluation metrics, and thus should be taken into account in the development of future richer evaluation metrics.
Drug-resistant tuberculosis can be predicted by Mycobacterial interspersed repetitive unit locus

It is unknown whether MIRU-VNTR (Mycobacterial Interspersed Repetitive Unit-Variable Number of Tandem Repeat) is associated with drug resistance of Mycobacterium tuberculosis. The purpose of this study was to explore the ability of 24 MIRU loci to predict the drug resistance of Isoniazid (INH), Rifampicin (RFP), Streptomycin (SM), Ethambutol (EMB) and Pyrazinamide (PZA). We collected the drug resistance and MIRU loci information of 109 strains of M. tuberculosis from an open database. The results of multivariate logistic regression showed that the VNTR polymorphism of MTUB04 was related to INH resistance [odds ratio (OR) = 2.82, P = 0.00], RFP resistance (OR = 1.91, P = 0.02), SM resistance (OR = 1.98, P = 0.01) and EMB resistance (OR = 1.95, P = 0.03). MIRU40 was associated with INH resistance (OR = 2.22, P = 0.00). MTUB21 was connected with INH resistance (OR = 1.63, P = 0.02) and SM resistance (OR = 1.69, P = 0.01). MIRU26 was correlated with SM resistance (OR = 1.52, P = 0.04). MIRU39 was associated with EMB resistance (OR = 4.07, P = 0.02). The prediction power of MIRU loci were 0.84, 0.70, 0.85, and 0.74 respectively for INH (predicted by MTUB04, MIRU20, and MTUB21), RFP (predicted by MTUB04), SM (predicted by MTUB21 and MIRU26) and EMB (MTUB04 and MIRU39) through ROC analysis. Our results showed that MIRU loci were related to anti-tuberculosis drug and could predict the drug resistance of tuberculosis.
Ybp2 Associates with the Central Kinetochore of Saccharomyces cerevisiae and Mediates Proper Mitotic Progression

The spindle checkpoint ensures the accurate segregation of chromosomes by monitoring the status of kinetochore attachment to microtubules. Simultaneous mutations in one of several kinetochore and cohesion genes and a spindle checkpoint gene cause a synthetic-lethal or synthetic-sick phenotype. A synthetic genetic array (SGA) analysis using a mad2Δ query mutant strain of yeast identified YBP2, a gene whose product shares sequence similarity with the product of YBP1, which is required for H2O2-induced oxidation of the transcription factor Yap1. ybp2Δ was sensitive to benomyl and accumulated at the mitotic stage of the cell cycle. Ybp2 physically associates with proteins of the COMA complex (Ctf19, Okp1, Mcm21, and Ame1) and 3 components of the Ndc80 complex (Ndc80, Nuf2, and Spc25 but not Spc24) in the central kinetochore and with Cse4 (the centromeric histone and CENP-A homolog). Chromatin-immunoprecipitation analyses revealed that Ybp2 associates specifically with CEN DNA. Furthermore, ybp2Δ showed synthetic-sick interactions with mutants of the genes that encode the COMA complex components. Ybp2 seems to be part of a macromolecular kinetochore complex and appears to contribute to the proper associations among the central kinetochore subcomplexes and the kinetochore-specific nucleosome.
Work-Related Injuries

Objective: To examine whether certain personal and workplace factors increase risk for work-related injuries among home health aides. Method: A cross-sectional analysis was conducted using data from the 2007 National Survey of Home Health Aides among workers who provided formal caregiving to older adults or people with disabilities (N = 3,377, weighted sample = 160,720). Results: Multivariate logistic regression identified six factors associated with injury: White race (OR = 2.07, 95% CI 1.18, 3.63); inappropriate workload (OR = 3.27, 95% CI 1.55, 6.93); having multiple jobs (OR = 2.73, 95% CI 1.30, 5.71); job dissatisfaction (OR = 2.71, 95% CI 1.23, 5.96); higher hourly pay rate (OR = 2.38, 95% CI 1.31, 4.33); and working in two locations (inpatient facility and patient’s home) compared with working in patient’s home only (OR = 2.57, 95% CI 1.51, 4.40). Discussion: Interventions should be developed to address preventable risk factors. Evaluations of candidate interventions should control for other related factors that are not modifiable.
Efficacy of Magnesium Trihydrate of Ursodeoxycholic Acid and Chenodeoxycholic Acid for Gallstone Dissolution: A Prospective Multicenter Trial

Background/Aims Cholecystectomy is necessary for the treatment of symptomatic or complicated gallbladder (GB) stones, but oral litholysis with bile acids is an attractive alternative therapeutic option for asymptomatic or mildly symptomatic patients. This study was conducted to evaluate the efficacy of magnesium trihydrate of ursodeoxycholic acid (UDCA) and chenodeoxycholic acid (CDCA) on gallstone dissolution and to investigate improvements in gallstone-related symptoms. Methods A prospective, multicenter, phase 4 clinical study to determine the efficacy of orally administered magnesium trihydrate of UDCA and CDCA was performed from January 2011 to June 2013. The inclusion criteria were GB stone diameter ≤15 mm, GB ejection fraction ≥50%, radiolucency on plain X-ray, and asymptomatic/mildly symptomatic patients. The patients were prescribed one capsule of magnesium trihydrate of UDCA and CDCA at breakfast and two capsules at bedtime for 6 months. The dissolution rate, response rate, and change in symptom score were evaluated. Results A total of 237 subjects were enrolled, and 195 subjects completed the treatment. The dissolution rate was 45.1% and the response rate was 47.2% (92/195) after 6 months of administration of magnesium trihydrate of UDCA and CDCA. Only the stone diameter was significantly associated with the response rate. Both the symptom score and the number of patients with symptoms significantly decreased regardless of stone dissolution. Adverse events necessitating discontinuation of the drug, surgery, or endoscopic management occurred in 2.5% (6/237) of patients. Conclusions Magnesium trihydrate of UDCA and CDCA is a well-tolerated bile acid that showed similar efficacy for gallstone dissolution and improvement of gallstone-related symptoms as that shown in previous studies.
Chemical composition and some biological activities of marine algae collected in Tunisia

The chemical composition and some biological properties of four algae (Ulva rigida, Codium bursa, Cystoseira barbata, and Ceramium diaphanum) collected from the Gabes Gulf area (Tunisia) were examined. Ash (11.35–29.08% weight/dry weight [w/dw]) and total sugar (13.20–18.70% w/dw) were the most abundant contents in these algae. Protein contents were moderate (5.03–14.00% w/dw), with the red alga (C. diaphanum) having the highest value. Lipid contents were within the range mentioned for seaweeds (less than 3% w/dw). Saturated fatty acids occurring at the highest proportions were C16:0 (24.53–41.37%) and C12:0 (10.37–24.44%). The most abundant monounsaturated fatty acid was C18:1n-9 (21.74–54.22%), whereas the most abundant polyunsaturated fatty acid was C18:2n-6 (9.57–11.71%). Variations in chemical composition can be attributed to both environmental and genetic differences among species. All algal extracts displayed antibacterial activity against Escherichia coli and Staphylococcus simulans (inhibition diameter: 10–25 mm), antioxidant activity (radical scavenging activity: 0.8–23%), and anti-inflammatory activity (48–61% inhibition of the phospholipase A2 activity); therefore, the marine algae examined can be considered abundant resources of bioactive molecules. Se evaluaron la composicion quimica y algunas propiedades biologicas de cuatro especies de algas (Ulva rigida, Codium bursa, Cystoseira barbata y Ceramium diaphanum) que se recolectaron en el Golfo de Gabes (Tunez). Los contenidos de cenizas (11.35–29.08% de peso/peso seco [p/ps]) y azucares totales (13.20–18.70% p/ps) fueron los mas abundantes en estas algas. El contenido de proteinas fue moderado (5.03–14.00% p/ps), y el alga roja C. diaphanum presento el valor mas alto. El contenido de lipidos estuvo dentro del intervalo determinado para algas marinas (menor a 3% p/ps). Los acidos grasos saturados que se encontraron en mayor proporcion fueron C16:0 (24.53–41.37%) y C12:0 (10.37–24.44%). El acido graso monoinsaturado mas abundante fue C18:1n-9 (21.74–54.22%), mientras que el acido graso poliinsaturado mas abundante fue C18:2n-6 (9.57–11.71%). Las variaciones en la composicion quimica se pueden atribuir a diferencias tanto ambientales como geneticas entre las especies. Todos los extractos de algas mostraron actividad antibacteriana contra Escherichia coli y Staphylococcus simulans (diametro de inhibicion: 10–25 mm), actividad antioxidante (actividad secuestrante de radicales libres: 0.8–23%) y actividad antiinflamatoria (48–61% de inhibicion de la actividad de la fosfolipasa A2); por lo tanto, las algas marinas estudiadas pueden ser consideradas como un recurso abundante de moleculas bioactivas.
Farmers’ Perception of Climate Variability and Change and Its Implication for Implementation of Climate-Smart Agricultural Practices

The main purpose of this study was to assess farmers’ perception on climate change and variability and its implication for adoption of climate -smart farming practices. A multi stage sampling procedure used to select the sample respondent households and the total sample size of the study was 138 households. Primary data were collected by using semi-structured interview, focus group discussion (FGDs) and key informant interviews. Both descriptive statistics and binary Logistic regression model were used as data analysis techniques for this study. The descriptive statistics analysis results indicated that about 88.73% of farmers believe that temperature in the district had become warmer and also over 90% respondents were recognized that rainfall volume, pattern, distribution and timing has changed, resulting in increased frequency of drought for prolonged period of time and high intensity rainfall for short periods of time. Though the majority of the responders perceived climate change problems, only 62.56 percent of the total respondents’ adopted climate-smart agricultural practices while the remaining 37.5 percent has not adapted climate change-smart agricultural practices. This could imply that though perception, knowledge and awareness of climate change and variability are at frontline prerequisite sequentially for adoption of climate change-smart agricultural practices decisions, it is not cure-all alone factor. The output of the binary logistic regression analyses proved that age of the household head, gender, education, farm experience, household size, and distance to the nearest market, access to irrigation water, local agro-ecology and access to information on climate change through extension services were found to have significant influence on the probability of farmers to perceive climate change and variability. With the level of perception to climate change being more than that of adaptation, the study suggests that more policy efforts should be geared towards helping farmers to adapt to climate change.
Demonstration of an Integrated LiNbO $_3$ Synchronized Double Phase Modulator and Its Application to Dual-Pump Fiber Optical Parametric Amplifiers and Wavelength Converters

We report the fabrication of an integrated LiNbO3 Y-junction synchronized double phase modulator fully packaged for RF-application up to 40 GHz. This optical modulator allows for delivering simultaneously counter-phase high-speed modulation and coupling for two input channels. It was designed for application to fiber-optical parametric amplifier and wavelength converters for suppressing idler spectral broadening and signal gain distortion caused by phase modulation itself. With this component, Idler spectral broadening suppression is experimentally demonstrated over all the parametric gain band of a two-pump parametric amplifier operating in the 1.55-mum region. In addition, we present a useful technique for straightforward and full coupling of the pumps and the signal.
Physiological Indices, Yield and Yield Attributes of Quinoa (Chenopodium quinoa Willd.) as Influenced by Dates of Sowing and Varied Crop Geometry

Quinoa is discovered as a healthy food by North Americans and Europeans in the 1970’s and its popularity is dramatically increased in recent years because it is gluten-free (helpful for diabetic patients) and high in protein. In India, quinoa was cultivated in an area of 440 hectares with an average yield of 1053 tonnes (Srinivasa Rao, 2015). It is cultivated in the world with an area of 126 thousand hectares in a production of 103 thousand tonnes. Bolivia in South America is the biggest producer of quinoa with 46 per cent of world International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 7 (2017) pp. 1023-1034 Journal homepage: http://www.ijcmas. com
Nuclear Receptor NR4A2 Orchestrates Th17 Cell-Mediated Autoimmune Inflammation via IL-21 Signalling

IL-17-producing CD4+ T helper 17 (Th17) cells are pathogenic in a range of human autoimmune diseases and corresponding animal models. We now demonstrate that such T cells infiltrating the target organ during the induction of experimental autoimmune encephalomyelitis (EAE) and experimental autoimmune uveoretinitis (EAU) specifically express NR4A2. Further, we reveal a critical involvement of NR4A2 in Th17 cell functions and Th17 cell-driven autoimmune diseases. When NR4A2 expression was blocked with siRNA, full Th17 differentiation was prevented in vitro: although cells expressed the master Th17 regulator, RORγt, they expressed reduced levels of IL-23R and were unable to produce IL-17 and IL-21. Notably, Th17 differentiation in the absence of NR4A2 was restored by exogenous IL-21, indicating that NR4A2 controls full maturation of Th17 cells via autocrine IL-21 signalling. Preventing NR4A2 expression in vivo by systemic treatment with NR4A2-specific siRNA also reduced Th17 effector responses and furthermore protected mice from EAE induction. In addition, the lack of disease was associated with a reduction in autocrine IL-21 production and IL-23R expression. Similar modulation of NR4A2 expression was also effective as an intervention, reversing established autoimmune responses and ameliorating clinical disease symptoms. Thus, NR4A2 appears to control Th17 differentiation and so plays an essential role in the development of Th17-mediated autoimmune disease. As NR4A2 is also upregulated during human autoimmune disease, targeting NR4A2 may provide a new therapeutic approach in treating autoimmune disease.
MOLECULAR ANALYSIS OF SOLIDASTER CV. LEMORE, A HYBRID GOLDENROD (ASTERACEAE)

analysis of nuclear ribosomal its and ets sequence data was used to assess the relationships of the garden ornamental solidaster cv. lemore, a cultivar that was at one time believed to be an intergeneric hybrid ( solidago × a ster ). part of the analysis involved assessment of the generic placement of one of its putative parents, the Upland white aster, solidago ptarmicoides. Because of its superficial external appearance this species is still often treated as an aster , although there is evidence from several sources that suggests it should be clas sified within solidago. phylogenetic analysis of the combined its and ets sequence data showed that there was strong support for the inclusion of s. ptarmicoides within solidago, based on its placement in a well supported clade composed of all other sampled species of the genus. the its sequence data of solidaster showed evidence of a hybrid origin based on the presence of several intraindividual base pair polymorphisms. cloning experiments recovered two different individual its sequences, one identical to that obtained from
Causes of Enhanced SST Variability over the Equatorial Atlantic and Its Relationship to the Atlantic Zonal Mode in CMIP5

AbstractA spurious band of enhanced sea surface temperature (SST) variance (SBEV) is identified over the northern equatorial Atlantic in the Geophysical Fluid Dynamics Laboratory (GFDL) Climate Model, version 2.1. The SBEV is especially pronounced in boreal spring owing to the combined effect of both anomalous atmospheric thermal forcing and oceanic vertical upwelling. The SBEV is a common bias in phase 5 of the Coupled Model Intercomparison Project (CMIP5), found in 14 out of 23 models. The SBEV in CMIP5 is associated with the atmospheric thermal forcing and the oceanic vertical upwelling, similar to GFDL CM2.1. While the tropical North Atlantic variability is only weakly correlated with the Atlantic zonal mode (AZM) in observations, the SBEV in CMIP5 produces conditions that drive and intensify the AZM variability via triggering the Bjerknes feedback. This partially explains why AZM is strong in some CMIP5 models even though the equatorial cold tongue and easterly trades are biased low.
Area spectrum of the Schwarzschild black hole.

We consider a Hamiltonian theory of spherically symmetric vacuum Einstein gravity under Kruskal-like boundary conditions in variables associated with the Einstein-Rosen wormhole throat. The configuration variable in the reduced classical theory is the radius of the throat, in a foliation that is frozen at the left hand side infinity but asymptotically Minkowski at the right hand side infinity, and such that the proper time at the throat agrees with the right hand side Minkowski time. The classical Hamiltonian is numerically equal to the Schwarzschild mass. Within a class of Hamiltonian quantizations, we show that the spectrum of the Hamiltonian operator is discrete and bounded below, and can be made positive definite. The large eigenvalues behave asymptotically as~$\sqrt{2k}$, where $k$ is an integer. The resulting area spectrum agrees with that proposed by Bekenstein and others. Analogous results hold in the presence of a negative cosmological constant and electric charge. The classical input that led to the quantum results is discussed.
