Interference-aware proportional fairness for multi-rate wireless networks

In this paper, we consider how proportional fairness in wireless networks is impacted by spatial reuse and the interference it produces. We observe that, in scenarios where spatial reuse is possible (e.g., in high-density WLAN environments), the classic notion of time-based proportional fairness can be severely impacted: some users might experience very large interference penalties while other users might get larger bandwidth proportions than what they would have received with time-based proportional fairness and no spatial reuse. To account for this, we introduce the concept of interference-aware STDMA time-based proportional fairness (i-STPF), and compare it to ordinary STDMA time-based proportional fairness (STPF). We present an εi-STPF scheduling algorithm, and prove that it approximates the time-based fair bandwidth allocation (up to a small positive constant ε), while providing an aggregate throughput that is within a constant factor from optimal. We also present a heuristic i-STPF scheduling algorithm and compare it through simulation to a similar heuristic STPF scheduler, and to an interference-aware, rate-based scheduler. The results show that the i-STPF scheduler: i) achieves excellent aggregate throughput about 35% higher than rate-based throughput; and ii) maintains a close approximation to time-based fairness without interference.
Molecules in Silico: A Graph Description of Chemical Reactions

A general mathematical description, mostly in terms of graph theory, is given for reactions of organic chemistry. The corresponding computer program generates all products that can result from a given set of starting materials interacting according to a given set of reaction schemes. Example reactions from combinatorial chemistry, synthetic organic chemistry, and mass spectroscopic structure elucidation are considered in detail.
Eight-vertex Model and Non-stationary Lame Equation

We study the ground state eigenvalues of Baxter's Q-operator for the eight-vertex model in a special case when it describes the off-critical deformation of the six-vertex model. We show that these eigenvalues satisfy a non-stationary Schrodinger equation with the time-dependent potential given by the Weierstrass elliptic -function where the modular parameter τ plays the role of (imaginary) time. In the scaling limit, the equation transforms into a 'non-stationary Mathieu equation' for the vacuum eigenvalues of the Q-operators in the finite-volume massive sine-Gordon model at the super-symmetric point, which is closely related to the theory of dilute polymers on a cylinder and the Painleve III equation.
Change Detection of the Vegetation Cover based upon Advanced Very High Resolution Radiometer (AVHRR) Data

The goal of the current study is to map location and extent of the changes in vegetation in north- eastern portion of The Kingdom of Saudi Arabia due to the 1991 Gulf War. AVHRR data acquired in different dates were the main source of information. Changes in vegetation during three different time periods may be related to smoke plume impact and / or military activities. The change detection analysis of the NDVI results showed a circular shaped area near the Kuwaiti border, had experienced the most vegetation loss in Saudi territory between the years 1989 and 1992. However, the results should be viewed with caution, as there are multiple potential sources of error including rainfall events prior to the image dates and varying amounts of atmospheric haze that possibly was not completely normalized. The results should be compared with other sources of ground information for validation. The most common technique for measuring vegetation change, based upon AVHRR data, was used without complication to detect some patterns of change.
Small ubiquitin-related modifier 1 is involved in hepatocellular carcinoma progression via mediating p65 nuclear translocation

Small ubiquitin-related modifier (SUMO) proteins participate in a post-translational modification called SUMOylation and regulate a variety of intracellular processes, such as targeting proteins for nuclear import. The nuclear transport of p65 results in the activation of NF-κB, and p65 contains several SUMO interacting motifs (SIMs). However, the relationship between p65 and SUMO1 in hepatocellular carcinoma (HCC) remains unclear. In this study, we demonstrated the potential roles of SUMO1 in HCC via the regulation of p65 subcellular localization. We found that either SUMO1- or p65-positive immunoreactivity was remarkably increased in the nuclei of tumor tissues in HCC patients compared with non-tumor tissues, and further analysis suggested a correlation between SUMO1- and nuclear p65-positive immunoreactivities (R = 0.851, P = 0.002). We also verified the interaction between p65 and SUMO1 in HCC by co-immunoprecipitation. TNF-α and hypoxia increased SUMO1 protein levels and enhanced SUMO1-modified p65 SUMOylation. Moreover, the knockdown of SUMO1 decreased p65 nuclear translocation and inhibited NF-κB transcriptional activity. Further the results of this study revealed that the knockdown of SUMO1 suppressed the proliferation and migration of hepatoma cells. These results suggest that SUMO1 contributes to HCC progression by promoting p65 nuclear translocation and regulating NF-κB activity.

Timed motor function tests capacity in healthy children

Objective Motor function tests are used clinically and in research in children, particularly in those with neuromuscular disorders. Timed function tests are recommended in the follow-up of patients with neuromuscular disorders. This study was designed to know how healthy children perform on simple timed motor function tests. Material and methods In a cross-sectional observational study, 345 children aged 2–12 years, followed at the Federal University of Rio de Janeiro's Institute of Paediatric, were evaluated. To be eligible they had to have acquired independent walking before the age of 14 months, be able to cope and willing to participate in the study. Anthropometric and vital signs were verified, as well as contact with smokers. The following timed motor function tests were measured: time to rise from the floor (TRF), time to walk 10 meters (10MWT) and time to run 10 meters (10MRT). Results Improvement in time to perform those motor functions was found to occur in healthy preschool children. Stabilisation of mean times for those motor functions was seen thereafter: TRF of 1.2 s, 10MWT of 10 s and 10MRT of 5 s. Conclusions Walking and rising speed improve with age in preschoolers, as expected, and is shown to occur up to a plateau level. Our findings for the 10MWT, 10MRT and TRF are in line with those published in 2008 for the 6 minute walk test (6MWT). The motor functions used in the present study require less time and space than the ones in the 6MWT. They should be considered more universally applicable. Those tests could be used in childcare clinics as a screening for motor disorders such as the neuromuscular diseases. Trial registration number 1.098. 302.
Isolation of Porcine Circovirus-like Viruses from Pigs with a Wasting Disease in the USA and Europe

Samples of lung, liver, kidney, pancreas, spleen, and lymph node from pigs with postweaning multisystemic wasting syndrome from California (USA) and samples of mesenteric lymph nodes from similarly diseased pigs from Brittany (France) were examined by light microscopy, in situ hybridization (ISH), and/or virus isolation. Whole genomic probes for porcine circovirus (PCV) and chicken anemia virus (CAV) were used for ISH. Tissue homogenate supernatants were inoculated onto PK/15 cells for virus isolation, and the presence of viral antigen and viral particles was verified by indirect immunofluorescence, ISH, and electron microscopy. Histologic examination of lung from pigs from California revealed interstitial pneumonia, alveolar epithelial hyperplasia, and basophilic nuclear and cytoplasmic inclusions in mononuclear cell infiltrates and various pulmonary epithelial cells. Granulomatous lymphadenitis with syncytial cells typified the lesions seen in the pigs from France. PCV-like nucleic acid was detected by ISH in lung, pancreas, lymph node, kidney, and liver in pigs from California. Positive signal was also obtained in lymph node sections from pigs from France. Probes for CAV were consistently negative. PK/15 cell cultures inoculated with lung preparations from diseased California pigs and mesenteric lymph node preparations from pigs from France had positive fluorescence by indirect staining for PCV using pooled polyclonal pig sera and hyperimmune rabbit serum and had variable staining with a panel of 7 monoclonal antibodies specific for cell culture contaminant PCV. PCV-like nucleic acid was also detected by ISH in cell cultures. Cytopathic effect was not observed Electron microscopic examination of inoculated cell cultures revealed 17-nm viral particles morphologically consistent with PCV No other virus particles were observed. Although genomic analysis for the definitive identification of these viral isolates remains to be done, the evidence provided strongly suggests that these tissue isolates are closely related to, although antigenically distinct from, the original PCV cell culture contaminant.
Association Between Systemic Inflammation and Incident Diabetes in HIV-Infected Patients After Initiation of Antiretroviral Therapy

OBJECTIVE To determine whether systemic inflammation after initiation of HIV-antiretroviral therapy (ART) is associated with the development of diabetes. RESEARCH DESIGN AND METHODS We conducted a nested case-control study, comparing 55 previously ART-naive individuals who developed diabetes 48 weeks after ART initiation (case subjects) with 55 individuals who did not develop diabetes during a comparable follow-up (control subjects), matched on baseline BMI and race/ethnicity. Stored plasma samples at treatment initiation (week 0) and 1 year later (week 48) were assayed for levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and the soluble receptors of tumor necrosis factor-α (sTNFR1 and sTNFR2). RESULTS Case subjects were older than control subjects (median age 41 vs. 37 years, P = 0.001), but the groups were otherwise comparable. Median levels for all markers, except hs-CRP, decreased from week 0 to week 48. Subjects with higher levels of hs-CRP, sTNFR1, and sTNFR2 at 48 weeks had an increased odds of subsequent diabetes, after adjustment for baseline marker level, age, BMI at week 48, CD4 count at week 48 (< vs. >200 cells/mm3), and indinavir use (all Ptrend ≤ 0.05). After further adjustment for week 48 glucose, effects were attenuated and only sTNFR1 remained significant (odds ratio, highest quartile vs. lowest 23.2 [95% CI 1.28–423], P = 0.03). CONCLUSIONS Inflammatory markers 48 weeks after ART initiation were associated with increased risk of diabetes. These findings suggest that systemic inflammation may contribute to diabetes pathogenesis among HIV-infected patients.
In-place transposition of rectangular matrices on accelerators

Matrix transposition is an important algorithmic building block for many numeric algorithms such as FFT. It has also been used to convert the storage layout of arrays. With more and more algebra libraries offloaded to GPUs, a high performance in-place transposition becomes necessary. Intuitively, in-place transposition should be a good fit for GPU architectures due to limited available on-board memory capacity and high throughput. However, direct application of CPU in-place transposition algorithms lacks the amount of parallelism and locality required by GPUs to achieve good performance. In this paper we present the first known in-place matrix transposition approach for the GPUs. Our implementation is based on a novel 3-stage transposition algorithm where each stage is performed using an elementary tiled-wise transposition. Additionally, when transposition is done as part of the memory transfer between GPU and host, our staged approach allows hiding transposition overhead by overlap with PCIe transfer. We show that the 3-stage algorithm allows larger tiles and achieves 3X speedup over a traditional 4-stage algorithm, with both algorithms based on our high-performance elementary transpositions on the GPU. We also show our proposed low-level optimizations improve the sustained throughput to more than 20 GB/s. Finally, we propose an asynchronous execution scheme that allows CPU threads to delegate in-place matrix transposition to GPU, achieving a throughput of more than 3.4 GB/s (including data transfers costs), and improving current multithreaded implementations of in-place transposition on CPU.
What's in a Name? Understanding Profile Name Reuse on Twitter

Users on Twitter are commonly identified by their profile names. These names are used when directly addressing users on Twitter, are part of their profile page URLs, and can become a trademark for popular accounts, with people referring to celebrities by their real name and their profile name, interchangeably. Twitter, however, has chosen to not permanently link profile names to their corresponding user accounts. In fact, Twitter allows users to change their profile name, and afterwards makes the old profile names available for other users to take. In this paper, we provide a large-scale study of the phenomenon of profile name reuse on Twitter. We show that this phenomenon is not uncommon, investigate the dynamics of profile name reuse, and characterize the accounts that are involved in it. We find that many of these accounts adopt abandoned profile names for questionable purposes, such as spreading malicious content, and using the profile name's popularity for search engine optimization. Finally, we show that this problem is not unique to Twitter (as other popular online social networks also release profile names) and argue that the risks involved with profile-name reuse outnumber the advantages provided by this feature.
CT Findings of Atypical Adenomatous Hyperplasia in the Lung

Objective The aim of this study was to analyze the computed tomographic (CT) findings of atypical adenomatous hyperplasia (AAH) in the lung. Materials and Methods The CT findings of AAHs in eight patients were retrospectively reviewed. The CT findings of each AAH lesion were evaluated for multiplicity, location, shape, size and internal density of the lesion, the interface between the normal lung and the lesion, the internal features within the lesion and any change of the lesion on the follow-up CT scans (range: 33 to 540 days; average: 145.3 days). Results The eight patients consisted of three men and five women (age range: 43-71 years). Six of eight patients were asymptomatic. Four of them (50%) had synchronous malignancies in the lung: adenocarcinoma of the lung (n = 3), and metastatic squamous cell carcinoma from the uterus (n = 1). We could identify and evaluate eleven AAH nodules in seven patients on the CT scans. Three patients had multiple AAHs. Seven of the 11 lesions (64%) were located in the upper lobe. All the AAHs showed a well-defined oval or round shape and pure ground-glass opacity (GGO) without any solid component (size: 3.9×3 mm to 19×17 mm; internal attenuation: -467 to -785 HU). All the AAHs showed no change of their size and internal density on the follow-up CT scans. Conclusion Atypical adenomatous hyperplasia is often associated with malignancy. This tumor is shown on CT as persistent well-defined oval or round nodular GGOs without solid components, and it does not change on the follow-up CT.
Comparison of dispersion compensation methods for 40Gbit/s WDM-PON transmission systems

The increasing number of end-users and growing demand for higher data rate affect fiber-optical transmission systems (FOTS), which need to catch up with the different performance requirements. Optical-fiber network still is the best solution for supporting high data rates and large distance coverage between network nodes. The most common destructive effect for FOTS is chromatic dispersion (CD) and the negative effect of CD FOTS increases with the increase of bitrate or optical fibers length. When one or both conditions are fulfilled the effect of chromatic dispersion must be taken into consideration but if it is ignored, dispersion can completely corrupt transmitted data because of intersymbol interference (ISI). In this paper authors demonstrate two dispersion compensation methods — dispersion compensation fiber (DCF) and fiber Bragg grating (FBG), for 16-channel 40Gbit/s per channel wavelength-division multiplexed C-band fiber-optical transmission systems with non-return-to-zero (NRZ) return-to-zero (RZ) line codes. The proposed passive optical network architecture with 40 Gbit/s transmission speed is fully in line with NG-PON2 architecture, according to ITU-T G.989. 1 recommendation. Main goal of this paper is to find out which of the above mentioned dispersion compensation methods have the most positive effect on the reach of fiber-optical transmission line, when RZ or NRZ coding is used, depending on the dispersion compensation module's (DCM's) location in optical distribution network. Therefore, through simulations, authors investigated multiple channel 100 GHz spaced WDM transmission systems, where both DCF and FGB dispersion compensation methods are used.
Ovarian cancer identification based on dimensionality reduction for high-throughput mass spectrometry data

MOTIVATION High-throughput and high-resolution mass spectrometry instruments are increasingly used for disease classification and therapeutic guidance. However, the analysis of immense amount of data poses considerable challenges. We have therefore developed a novel method for dimensionality reduction and tested on a published ovarian high-resolution SELDI-TOF dataset. RESULTS We have developed a four-step strategy for data preprocessing based on: (1) binning, (2) Kolmogorov-Smirnov test, (3) restriction of coefficient of variation and (4) wavelet analysis. Subsequently, support vector machines were used for classification. The developed method achieves an average sensitivity of 97.38% (sd = 0.0125) and an average specificity of 93.30% (sd = 0.0174) in 1000 independent k-fold cross-validations, where k = 2, . , 10. AVAILABILITY The software is available for academic and non-commercial institutions.
The counter‐propagating Rossby‐wave perspective on baroclinic instability. II: Application to the Charney model

The constant‐density Charney model describes the simplest unstable basic state with a planetary‐vorticity gradient, which is uniform and positive, and baroclinicity that is manifest as a negative contribution to the potential‐vorticity (PV) gradient at the ground and positive vertical wind shear. Together, these ingredients satisfy the necessary conditions for baroclinic instability. In Part I it was shown how baroclinic growth on a general zonal basic state can be viewed as the interaction of pairs of ‘counter‐propagating Rossby waves’ (CRWs) that can be constructed from a growing normal mode and its decaying complex conjugate. In this paper the normal‐mode solutions for the Charney model are studied from the CRW perspective.
Preparation of Chitosan Coated Magnetic Hydroxyapatite Nanoparticles and Application for Adsorption of Reactive Blue 19 and Ni2+ Ions

An adsorbent called chitosan coated magnetic hydroxyapatite nanoparticles (CS-MHAP) was prepared with the purpose of improvement for the removal of Ni2+ ions and textile dye by coprecipitation. Structure and properties of CS-MHAP were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and vibrating sample magnetometer (VSM). Weight percent of chitosan was investigated by thermal gravimetric analysis (TGA). The prepared CS-MHAP presents a significant improvement on the removal efficiency of Ni2+ ions and reactive blue 19 dye (RB19) in comparison with chitosan and magnetic hydroxyapatite nanoparticles. Moreover, the adsorption capacities were affected by several parameters such as contact time, initial concentration, adsorbent dosage, and initial pH. Interestingly, the prepared adsorbent could be easily recycled from an aqueous solution by an external magnet and reused for adsorption with high removal efficiency.
Efficacy of nebulized fluticasone propionate compared with oral prednisolone in children with an acute exacerbation of asthma.

The aim of the present study was to investigate the efficacy and safety of nebulized fluticasone propionate (FP Nebules) compared with oral soluble prednisolone in children with an acute exacerbation of asthma. The study used an international, multi-centre, randomized, double-blind, parallel group design. Three hundred and twenty-one patients, aged 4-16 years old, who presented with an acute exacerbation of asthma, were randomly allocated to either nebulized FP (1 mg b.d.) or oral prednisolone (2 mg kg(-1) day(-1) for 4 days then 1 mg kg(-1) day(-1) for 3 days) for 7 days. Patients in the FP group showed a significantly greater increase in diary card morning peak expiratory flow (PEF) over 7 days compared with patients in the prednisolone group (difference = 9.51 min(-1), CI = 2.1, 16.8, P = 0.034). Similar increases for both treatments were shown for evening PEF. Clinic PEF improved with both treatments, but was significantly greater in patients taking FP after 7 days (difference = 11.41 min(-1), CI = 2.8, 20.0, P = 0.029). Both treatments reduced symptom scores to a similar extent. The two treatments were well tolerated, and there was no difference in the incidence of adverse events. The present study demonstrated that nebulized FP is at least as effective as oral prednisolone in the treatment of children presenting with an acute exacerbation of asthma.
Cardiovascular and neurophysiologic correlates of sensory intake and rejection. I. Effect of cognitive tasks.

In this study of the relationship between sensory processing and cardiovascular function, five cardiovascular parameters were monitored during baseline periods and during tasks requiring either sensory intake or sensory rejection behavior on the part of 19 subjects. Sensory intake behavior was associated with a pattern of response similar lo that seen with activation of peripheral sympathetic nerves-vasoconstriction in both the digit (skin) and forearm (skeletal muscle). In contrast, sensory rejection behavior was associated with vasodilatation in the forearm and vasoconstriction in the digit. Individual differences in an EEG measure of characteristic ways of processing sensory information were predictably associated with differences in resting cardiovascular function. The association of sensory intake with a skeletal muscle vasoconstriction may help to extend our understanding of the physiology of sensory processing, since heretofore only heart rate and somatic motor activity have reliably differentiated sensory intake from sensory rejection behavior.
