High quality sound from small loudspeakers using the exact inverse (2005)

To compensate for the distortions of the electro-acoustic conversion in small loudspeakers, the signal is passed through a predistortion filter placed between the audio signal source and the loudspeaker. Volterra based predistortion filters are generally used to compensate for loudspeaker distortions. At high playback levels, Volterra preinverse may not improve the perceptual quality. At adaptive precompensator based on the exact inverse of the Volterra model is presented. The technique adjusts the precompensator parameters to minimize the instantaneous error between the input and the compensated output of the loudspeaker. The exact inverse has superior performance at high playback levels resulting in higher perceptual quality.

Representing Big Data as Networks: New Methods and Insights (2017)

Our world produces massive data every day; they exist in diverse forms, from pairwise data and matrix to time series and trajectories. Meanwhile, we have access to the versatile toolkit of network analysis. Networks also have different forms; from simple networks to higher-order network, each representation has different capabilities in carrying information. For researchers who want to leverage the power of the network toolkit, and apply it beyond networks data to sequential data, diffusion data, and many more, the question is: how to represent big data and networks? This dissertation makes a first step to answering the question. It proposes the higher-order network, which is a critical piece for representing higher-order interaction data; it introduces a scalable algorithm for building the network, and visualization tools for interactive exploration. Finally, it presents broad applications of the higher-order network in the real-world.
Novel Acoustic Technique for UXO Discrimination (2001)

Abstract : Recent demonstrations have shown that magnetic and electromagnetic induction technology can reliably detect most buried unexploded ordnance (UXO). Unfortunately, current technology is unable to reliably discriminate between UXO and other items that pose no risk, and typical survey methods currently deployed have an excessive level of false alarms (i.e. marking of sub-surface anomalies that do not correspond to UXO). There is a need for systems that, when cued by standard survey technologies, can cost effectively, non-invasively interrogate the suspected item and discriminate. One distinguishing characteristic of UXO is its shape: projectiles, mortars, bombs and rockets are characteristically long and slender. Over the past few years, several Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) sponsored projects have shown varying degrees of success in developing techniques for using magnetics and electromagnetic induction to discriminate between different target shapes [1]. This report documents the results of a SERDP Exploratory Development (SEED) project that applies a complementary sensor technology to the problem. The objective of the project was to demonstrate that relatively simple seismic technology routinely used for pavement and soil mechanical analysis can be used for classification and discrimination of buried objects. This report has six sections. Following this introduction, section 2 gives the background for the project, and the basic concept is described in section 3. Details of the experimental work done for this project are documented in section 4, and our conclusions are presented in section 5. Section 6 lists references cited in the report. Because of shortcomings of the instrumentation used in this project, the results are not conclusive. We measured signals that are qualitatively similar to those expected on the basis of numerical studies, but the spatial and freque
Prevalence of and risk factors associated with faecal carriage of CTX-M  -lactamase-producing Enterobacteriaceae in rural Thai communities (2012)

Faecal carriage of CTX-M-type ESBL-producing Enterobacteriaceae among asymptomatic individuals in rural Thailand remains alarmingly high, and previous antibiotic use and a history of hospitalization may contribute to its dissemination.
YOLO based Detection and Classification of Objects in video records (2018)

The primitive machine learning algorithms that are present break down each problem into small modules and solve them individually. Nowadays requirement of detection algorithm is to work end to end and take less time to compute. Real-time detection and classification of objects from video records provide the foundation for generating many kinds of analytical aspects such as the amount of traffic in a particular area over the years or the total population in an area. In practice, the task usually encounters slow processing of classification and detection or the occurrence of erroneous detection due to the incorporation of small and lightweight datasets. To overcome these issues, YOLO (You Only Look Once) based detection and classification approach (YOLOv2) for improving the computation and processing speed and at the same time efficiently identify the objects in the video records. The classification algorithm creates a bounding box for every class of objects for which it is trained, and generates an annotation describing the particular class of object. The YOLO based detection and classification (YOLOv2) use of GPU (Graphics Processing Unit) to increase the computation speed and processes at 40 frames per second.
p62 targeting to the autophagosome formation site requires self-oligomerization but not LC3 binding (2011)

Autophagy is an intracellular degradation process by which cytoplasmic contents are degraded in the lysosome. In addition to nonselective engulfment of cytoplasmic materials, the autophagosomal membrane can selectively recognize specific proteins and organelles. It is generally believed that the major selective substrate (or cargo receptor) p62 is recruited to the autophagosomal membrane through interaction with LC3. In this study, we analyzed loading of p62 and its related protein NBR1 and found that they localize to the endoplasmic reticulum (ER)-associated autophagosome formation site independently of LC3 localization to membranes. p62 colocalizes with upstream autophagy factors such as ULK1 and VMP1 even when autophagosome formation is blocked by wortmannin or FIP200 knockout. Self-oligomerization of p62 is essential for its localization to the autophagosome formation site. These results suggest that p62 localizes to the autophagosome formation site on the ER, where autophagosomes are nucleated. This process is similar to the yeast cytoplasm to vacuole targeting pathway.
Copper(II) Ethylene Polymerization Catalysts: Do They Really Exist? (2008)

The reactions of two types of copper(II) ethylene polymerization catalysts, [(sal)CuCl]2 (sal = 2-{C(H)═N(2,6-iPr2-C6H3)}-4,6-tBu2-phenoxide) and (α-diimine)CuCl2 (α-diimine = [(2,6-iPr2-C6H3)N═C(Me)]2), with methylaluminoxane (MAO) and trimethylaluminum (TMA) have been investigated. In both examples, facile and irreversible ligand (L) transfer from copper to TMA present in MAO was observed, resulting in formation of the corresponding (sal)AlMe2 and (imino-amido)AlMe2 complexes. The (imino-amido)AlMe2 complex is formed by α-diimine ligand transfer to aluminum followed by alkylation of one imino moiety in the ligand backbone. Both aluminum complexes were active catalysts for ethylene polymerization with activities similar to their Cu(II) precursors. Simple addition of a neutral salicylaldimine or α-diimine ligand to MAO in the absence of any copper species resulted in the formation of the corresponding LAlMe2 complexes, which are again active for ethylene polymerization. These results indicate that ethylene polymerization does not occur by a migratory insertion mechanism at the copper center, but is the result of ligand transfer to aluminum, and it is the resulting LAlMe2/LAlMe+ complexes that are likely the active species.

Intrusion detection using clustering (2010)

In increasing trends of network environment every one gets connected to the system. So there is need of securing information, because there are lots of security threats are present in network environment. A number of techniques are available for intrusion detection. Data mining is the one of the efficient techniques available for intrusion detection. Data mining techniques may be supervised or unsuprevised.Various Author have applied various clustering algorithm for intrusion detection, but all of these are suffers form class dominance, force assignment and No Class problem. This paper proposes a hybrid model to overcome these problems. The performance of proposed model is evaluated over KDD Cup 1999 data set.

Polymer micro-ring resonator integrated with a fiber ring laser for ultrasound detection (2017)

Polymer micro-ring resonators fabricated by a direct laser writing technique are presented as sensors for ultrasound detection. The optical micro-ring resonator consists of a micro-ring waveguide that acts as a wavelength selective feedback mirror to an erbium-doped fiber-ring laser (FRL). The micro-ring resonator reflection spectrum determines the lasing frequencies of the FRL. Acoustic waves, which cause strain or deformation of the micro-ring resonator, lead to shifts of the resonance wavelength and thereby shifts in the FRL lasing spectrum. The spectral shifts are demodulated using an unbalanced Michelson interferometer. The experiments demonstrate that polymer micro-ring resonators integrated with a FRL can be used as adaptive high-frequency ultrasound detectors.
Effects of the prophylactic use of escitalopram on the prognosis and the plasma copeptin level in patients with acute cerebral infarction (2020)

This study aimed to investigate whether the routine administration of escitalopram for three months would improve the prognosis of patients with ischemic stroke and decrease the plasma copeptin level. A total of 97 patients with acute cerebral infarction were randomly allocated to receive escitalopram (5-10 mg once per day, orally; n=49) or not to receive escitalopram (control group; n=48) for 12 weeks starting at 2-7 days after the onset of stroke. Both groups received conventional treatments, including physiotherapy and secondary prevention of stroke. The National Institutes of Health Stroke Scale (NIHSS) score was used to evaluate the disability of patients at the initial evaluation and at the monthly follow-up visits for three months. Impairment in the daily activities was assessed using the Barthel Index (BI), while cognitive impairment was assessed using Mini-Mental State Examination (MMSE) score. The psychiatric assessment included the administration of the Present State Examination modified to identify Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) symptoms of depression. The severity of depression was measured using the 17-item Hamilton Rating Scale for Depression (HAMD). During the 3-month follow-up period, 95 patients were included in the analysis (two patients withdrew from the escitalopram group). NIHSS and BI improvement at the 90th day were significantly greater in the escitalopram group (P<0.05), while HAMD and plasma copeptin levels significantly decreased, compared to the control group (P<0.01). In patients with acute ischemic stroke, the earlier administration of escitalopram for three months may improve neurological functional prognosis and decrease copeptin level.
Pupil dilation to illusory motion in peripheral drift images: Perception versus reality (2017)

Peripheral drift is a specific type of illusory motion that causes observers to perceive motion in a static image. We aimed to determine whether pupil dilation occurs during the perception of illusory motion. In three experiments investigating pupil-size changes to peripheral drift, pupil response differences were observed between symmetric patterns (SPs) that elicited no impression of motion and repeated asymmetric patterns (RAPs) that did. All participants reported the perception of motion in the RAP condition and showed significantly greater pupil dilation to these stimuli as compared with viewing stimuli in the SP condition. As a follow-up, we manipulated the RAP stimuli to reduce and then remove the illusion to determine (a) whether it was the asymmetry per se that induced the pupil dilation and (b) whether the amount of pupil dilation was contingent on the amount of observed illusory motion. Although a reduction in perceived illusory motion did not produce a reduction in pupil dilation, removal of the illusory motion did. Despite previous evidence reporting pupil constriction to the perception of motion, and the positive valence associated with symmetry, these experiments show that pupil dilation occurs during the perception of illusory motion. This is in keeping with previous evidence that pupil dilation is influenced by perceptual factors and not simply light level, and, in particular, shows that illusory motion is physiologically arousing.

The Effects of Vitamin D Supplementation on Biomarkers of Inflammation and Oxidative Stress Among Women with Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis of Randomized Controlled Trials (2018)

The current systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of vitamin D supplementation on biomarkers of inflammation and oxidative stress among women with polycystic ovary syndrome (PCOS). Cochrane library, Embase, PubMed, and Web of Science database were searched to identify related randomized-controlled articles (RCTs) published up to November 2017. Two researchers assessed study eligibility, extracted data, and evaluated risk of bias of included RCTs, independently. To check heterogeneity Q-test and I<sup>2</sup> statistics were used. Data were pooled by using the random-effect model and standardized mean difference (SMD) was considered as summary effect size. Seven RCTs were included into our meta-analysis. The findings showed that vitamin D supplementation in women with PCOS significantly decreased high-sensitivity C-reactive protein (hs-CRP) (SMD -1.03; 95% CI, -1.58, -0.49; p <0.001) and malondialdehyde (MDA) (SMD -1.64, 95% CI -2.26 to -1.02, p <0.001), and significantly increased total antioxidant capacity (TAC) levels (SMD 0.86, 95% CI 0.08 to 1.64, p=0.03). Vitamin D supplementation had no significant effect on nitric oxide (NO) (SMD 0.11, 95% CI -0.44 to 0.66, p=0.69) and total glutathione (GSH) levels (SMD 0.54, 95% CI -0.20 to 1.28, p=0.15). Overall, the current meta-analysis demonstrated that vitamin D supplementation to women with PCOS resulted in an improvement in hs-CRP, MDA and TAC, but did not affect NO and GSH levels.

High Total Dissolved Solids Water Treatment by Charged Nanofiltration Membranes Relating to Power Plant Applications (2016)

Selective desalination through nanofiltration (NF) is of great interest for many industrial applications including reuse of power plant scrubber wastewater and treatment of water containing high concentrations of TDS (total dissolved solids). This work seeks to understand the effect ion interactions at the membrane interface have on rejection and flux performance of charged NF membranes. NF membranes were also effective for low energy desalination of scrubber wastewater from Georgia Power Plant Bowen, composed primarily of Ca<sup>2+</sup>, Mg<sup>2+</sup>, Cl<sup>-</sup>, and SO<sub>4</sub> <sup>2-</sup>. As NF membranes have the capability for selective separations, 80% water recovery was achieved experimentally while maintaining an overall rejection of over 60% for Ca<sup>2+</sup> and Cl<sup>-</sup>. The occurrence of CaSO<sub>4</sub> precipitation at high water recovery was observed. The effect of precipitation on osmotic pressure and the effect of Cl<sup>-</sup> counterions on increasing gypsum solubility were explored for water recovery operation. This work expands on a previous work on the topics of desalination of multi-ionic solutions by incorporating the use of large scale membrane modules (0.59 m<sup>2</sup>) with several synthetic solutions as well as actual scrubber water containing precipitating elements, Ca<sup>2+</sup> and SO<sub>4</sub> <sup>2-</sup>. It was observed that the spiral wound membrane modules maintained a stable water permeability over the 144 day course of tests.
&lt;i&gt;Salvadora persica&lt;/i&gt; (Miswak): Antioxidant and Promising Antiangiogenic Insights (2018)

The use of plants to improve dental health and to promote oral hygiene has been practiced for centuries and persists in several communities throughout the world. Salvadora persica (Miswak) has a wide geographic distribution. The ancient Arabs had the habit of using it to whiten and polish the teeth. Here, we determined in vitro antioxidant activity, total phenols and flavonoids and evaluated antiproliferative activity of the extract of S. persica (Miswak). The MTT assay was used to estimate the antiproliferative activities of the extract against human hepatoma (HepG2) cancer cell line. Inhibition percentage of DPPH scavenging activity was dose-dependent and ranged from (30.7% ± 0.62) to (5.89% ± 0.98). The phenolic content was (2.7 ± 0.11) mg GAE/g while the flavonoid content was (2.70 ± 0.45) mg QE/g. Antiproliferative results of the extracts were found to be consistent with their antioxidant activity. Our extract also exhibited clear antiangiogenic activity. These findings introduce S. persica as the useful and novel potential anti-tumor agent for hepatocellular carcinoma (HCC) treatment.
EVIDENCE FOR AN AIRBORNE SEX PHEROMONE IN THE COLORADO POTATO BEETLE, <i>LEPTINOTARSA DECEMLINEATA</i> (1997)

Abstract Trials using four different sex combinations of Colorado potato beetle, Leptinotarsa decemlineata Say, demonstrated that male beetles move upwind towards females, whereas no attraction was seen between any of the other combinations. Attraction was not found to increase significantly after the female reached 10 days old. Visual stimuli appear to be unimportant from a distance of 50 cm. Orientation behaviour by the male beetle was observed as it walked upwind towards the female; no identifiable calling behaviour by the female was observed. The data indicate a sex pheromone is being produced by the female and is used by the male for mate location from a distance.
