Effect of Cell Phone Exposure on Physiologic and Hematologic Parameters of Male Medical Students in Bijapur (Karnataka) with Reference to Serum Lipid Profile (2010)

The public awareness about cell phone safety increased greatly in the last few years as various reports of potential adverse health effects on humans exposed to radiations emitted from cellular phones were published. The aim of the study was to assess the effect of long term cell phone exposure on physiological and hematological parameters along with its impact on serum lipid profiles and a single call effect on heart rate, blood pressure and SpO2(%) of healthy male medical students. The students were divided into two groups, group I (n=22, age 20.63 +/- 1.17 yrs) comprising first year medical students who were never exposed to cell phones at the time of this study and group II (n=35, age 22.00 +/- 1.56 yrs) consists of final year (fourth year) male medical students who were using cell phone for more than four years before this study. The results showed no significant differences the groups in basal heart rate, systolic blood pressure, SpO2(%), or various hematologic parameters. Acute exposure (single call of cell phone with 900 MHz for 1 minute) in both groups showed a significant increase in peak heart rate in group II as compared with group I and a significant decrease in peak SpO2 (%) in group I as compared with group II. Serum total cholesterol, VLDL-cholesterol, and triglycerides concentration were significantly higher in group II (long term cell phone exposed) than in group I, suggesting a mild alteration of lipid profile among group II subjects.
Effects of 2,3-Bis(4-hydroxyphenyl)-propionitrile on Induction of Polyovular Follicles in the Mouse Ovary (2018)

Since SF1 is an important transcription factor of several genes involved in ovarian function, up-regulation of Sf1 expression by neonatal exposure to DPN, through ERβ, might affect expression of Gdf9, Mis and Star, resulting in increased PFs in mouse ovary.
CPU-assisted GPU thread pool model for dynamic task parallelism (2015)

With the growing power of GPUs, how to utilize the high computing performance provided by the GPU hardware becomes an urgent yet challenging problem, especially for applications with fine grained parallelism. Task programming is efficient for handling fine grained parallelism but current GPU task parallel solutions using either concurrent kernel execution (CKE) or persistent kernels suffer from a high cost of CPU-GPU interaction. The page-locked host memory supported by new generation GPUs turns CPU-GPU heterogeneous systems into the non-uniform memory access (NUMA) architecture, making it possible to improve CPU-GPU interaction with shared memory programming. In this paper, we propose the CPU-assisted GPU thread pool (CAGTP) model that combines data parallelism and task parallelism at the thread block level to support applications with fine grained parallelism. In the CAGTP model, the Computing Block Level task Scheduling (CBLS) method is designed in which task slots allocated in the page-locked host memory eliminate competition among thread blocks. A separate host scheduler is designed for scheduling tasks to thread blocks and the overhead for scheduling a task (200ns) is much lower than that of similar systems. Experiment results show that the CAGTP model supports fine grained task parallelism with or without dependencies efficiently. It outperforms CKE for batched GEMMs, Cholesky factorization and mixed workloads.
Sand-castle biperiodic pattern for spectral and angular broadening of antireflective properties (2010)

This Letter deals with the antireflective properties of top-patterned pyramids, looking like sand castles, bi-periodically repeated on a silicon surface. It is demonstrated numerically that such an original pattern allows a dramatic spectral and angular broadening of the antireflective efficiency. Design examples are given for wavelengths ranging from 0.5 microm to 5 microm and incidence angles of 30 degrees and 45 degrees. Applications of such antireflective surfaces on photodetectors and solar cells are soon expected.
Segmenting subregions of the human hippocampus on structural magnetic resonance image scans: An illustrated tutorial (2017)

As hippocampal subregion segmentation is an evolving field of research, we do not suggest this protocol is definitive or final. Rather, we present a fully explained and expedient method of manual segmentation which remains faithful to our current understanding of human hippocampal neuroanatomy. We hope that this 'tutorial'-style guide, which can be followed by experts and non-experts alike, will be a practical resource for clinical and research scientists with an interest in the human hippocampus.
Radioiodinated branched-chain fatty acids: substrates for beta oxidation? Concise communication. (1984)

Branched-chain iodinated fatty acids have been proposed for use as myocardial imaging agents. Several omega- iodoalkyl and omega- iodoaryl beta-methyl branched fatty acids have been synthesized and tested in rats. Myocardial activity levels at t = 5 min are affected by chain length for both alkyl and aryl acids, with chain lengths of 16 carbons possessing higher levels of activity than shorter lengths. Branching significantly lowers heart-to-blood ratios relative to straight-chain analogs. The degree of branching also affects radioactivity levels. Monoalkylation at the beta-carbon does not reduce the levels for omega- iodoalkyl fatty acids, but dialkylation reduces the levels significantly. Branching in the omega- iodoaryl series of fatty acids altered the time course of activity in the myocardium from a level of activity decreasing with time for the straight-chain acid to an essentially constant level of activity for the branched analogs.
Commercial Frequency AC to High Frequency AC Converter With Boost-Active Clamp Bridge Single Stage ZVS-PWM Inverter (2008)

This paper presents a novel soft-switching pulsewidth modulation (PWM) utility frequency ac to high frequency (HF) ac power conversion circuit incorporating boost-active clamp single stage inverter topology. This power converter is more suitable and acceptable for cost effective HF consumer induction heating applications. Its operating principle is presented using the switching mode equivalent circuits in addition to the operating voltage and current waveforms. The operating performances of this high frequency inverter using the latest insulated gate bipolar transistors are illustrated, which includes HFAC power regulation ranges and actual efficiency characteristics based on zero voltage soft switching operation ranges and the power dissipation loss analysis as compared with those of the previously developed high frequency inverter. In addition, a dual mode selected control scheme of this high frequency inverter based on a constant frequency asymmetrical PWM and pulse density modulation control scheme is discussed in this paper in order to extend the soft switching operation ranges and to improve the power conversion efficiency at the low power settings. The practical effectiveness of this power frequency converter is substantially proved on the basis of experimental results from practical design example.
Indigo‐Metal Complexes: Synthesis and Structure of Pd<sup>II</sup> and Pt<sup>II</sup> Compounds Containing the Anions of Indigo and Octahydroindigo as Mono‐ and Bis‐Chelate Ligands (1989)

Indigo-metal complexes, which have now been obtained for the first time in soluble, crystalline form, could be useful as energy transfer agents or catalysts. Two palladium(II) complexes with indigo as mono-chelate ligand (cf. 1) or octahydroindigo as bischelate ligand have been characterized by X-ray structure analyses. Intra- and intermolecular NH…︁O bridges of the free indigo are absent in complex 1.
Acute and 3-Month Performance of a Communicating Leadless Antitachycardia Pacemaker and Subcutaneous Implantable Defibrillator (2017)

This study presents the preclinical acute and chronic performance of the combined function of an ATP-enabled LP and S-ICD. Appropriate VVI functionality, successful wireless device-device communication, and ATP delivery were demonstrated by the LP. Clinical studies on safety and performance are needed.
The pancreas responds to remote damage and systemic stress by secretion of the pancreatic secretory proteins PSP/regI and PAP/regIII (2017)

The pancreas reacts to remote lesions and septic insults in mice and rats with increased PSP synthesis, while PAP is selectively responsive to septic events. Furthermore, our results suggest that serum PSP in septic patients is predominantly derived through an acute phase response of the pancreas.
Set Domain-Dependent Regulation of Transcriptional Silencing and Growth Control by SUV39H1, a Mammalian Ortholog of <i>Drosophila</i> Su(var)3-9 (2000)

Mammalian SET domain-containing proteins define a distinctive class of chromatin-associated factors that are targets for growth control signals and oncogenic activation. SUV39H1, a mammalian ortholog of Drosophila Su(var)3-9, contains both SET and chromo domains, signature motifs for proteins that contribute to epigenetic control of gene expression through effects on the regional organization of chromatin structure. In this report we demonstrate that SUV39H1 represses transcription in a transient transcriptional assay when tethered to DNA through the GAL4 DNA binding domain. Under these conditions, SUV39H1 displays features of a long-range repressor capable of acting over several kilobases to silence basal promoters. A possible role in chromatin-mediated gene silencing is supported by the localization of exogenously expressed SUV39H1 to nuclear bodies with morphologic features suggestive of heterochromatin in interphase cells. In addition, we show that SUV39H1 is phosphorylated specifically at the G(1)/S cell cycle transition and when forcibly expressed suppresses cell growth. Growth suppression as well as the ability of SUV39H1 to form nuclear bodies and silence transcription are antagonized by the oncogenic antiphosphatase Sbf1 that when hyperexpressed interacts with the SET domain and stabilizes the phosphorylated form of SUV39H1. These studies suggest a phosphorylation-dependent mechanism for regulating the chromatin organizing activity of a mammalian su(var) protein and implicate the SET domain as a gatekeeper motif that integrates upstream signaling pathways to epigenetic regulation and growth control.

Protection and control system upgrade based on IEC- 61850 and PRP (2014)

Over the past decade IEC 61850 has gained in popularity in various utilities across the globe for its promise of interoperability, scalability, maintainability and wire reduction. However the application and acceptance of this standard is still in its infancy in the province of Alberta, Canada. This paper presents a case study of one of the first protection system upgrade projects applying the IEC 61850 standard in the province. The focus of this paper is not to discuss the theoretical background of the standard itself. Rather, the purpose is to share and demonstrate the engineering steps taken and lessons learned to successfully implement a fully functional protection and control system based around IEC 61850. The complete system developed for this project includes the following elements: 1) 138/25kV distribution substation consisting of two power transformers and ten feeders. 2) Integration of 17 IEC 61850 compliant intelligent electronic devices (IED) to perform both protection and control (P&C) functions. 3) Substation local area network (LAN) using optical fiber for inter-panel communication and applying the parallel redundancy protocol (PRP) to achieve complete communication redundancy. ) New human-machine interface (HMIs) combining supervisory control and data acquisition (SCADA) and data gateway functionality within the real-time process database of the substation hardened computer. The paper begins with a high-level overview of the substation configuration and its P&C requirements. System protection and apparatus control philosophies using the IED and HMI/gateway are described. The applications and steps adopted to engineer inter-IED communication via generic object oriented substation events (GOOSE) are discussed in details. Next, the benefits of factory acceptance testing and the scope of site commissioning taken to verify the correct operation of the system are described. The paper concludes with a lessons learned section comparing this project with the traditional implementation.
3- and 4-phosphorylated phosphatidylinositols in the aquatic plant <i>Spirodela polyrhiza</i> L (1992)

Labelling of Spirodela polyrhiza L. plants with [3H]inositol and [32P]Pi yielded a series of phosphoinositides which were identified as PtdIns, PtdIns4P and PtdIns(4,5)P2. In addition, systematic degradation of a phospholipid extract identified PtdIns3P. Analysis of the distribution of 32P label between the monoester and diester phosphate groups of PtdIns3P and PtdIns4P revealed differences in the labelling of the monoester phosphate, suggesting that the two PtdInsP species are not synthesized or metabolized in a co-ordinate manner.
Rigid polyurethane foam prepared from a rape seed oil based polyol (2002)

Abstract A new kind of polyol based on rape seed oil for use in rigid polyurethane foam was synthesized and characterized. The synthesis of such a polyol was divided into two steps. The first step was the hydroxylation of the double bonds existing in the long chains of the unsaturated aliphatic hydrocarbon of rape seed oil with peroxy acid. The second step was use of the alcoholysis of the hydroxylated rape seed oil with triethanolamine to increase the hydroxyl value of the product. The reaction process was monitored by means of a novel on‐line infrared spectrometer. Rigid polyurethane foam was produced with this rape seed oil based polyol and some physical properties of the foam were examined and compared with a reference foam. © 2002 Wiley Periodicals, Inc.

YOLOv4: Optimal Speed and Accuracy of Object Detection (2020)

There are a huge number of features which are said to improve Convolutional Neural Network (CNN) accuracy. Practical testing of combinations of such features on large datasets, and theoretical justification of the result, is required. Some features operate on certain models exclusively and for certain problems exclusively, or only for small-scale datasets; while some features, such as batch-normalization and residual-connections, are applicable to the majority of models, tasks, and datasets. We assume that such universal features include Weighted-Residual-Connections (WRC), Cross-Stage-Partial-connections (CSP), Cross mini-Batch Normalization (CmBN), Self-adversarial-training (SAT) and Mish-activation. We use new features: WRC, CSP, CmBN, SAT, Mish activation, Mosaic data augmentation, CmBN, DropBlock regularization, and CIoU loss, and combine some of them to achieve state-of-the-art results: 43.5% AP (65.7% AP50) for the MS COCO dataset at a realtime speed of ~65 FPS on Tesla V100.

QoS in best-effort networks (2002)

The QoS of today's best-effort network does not deliver the performance required for a wide range of interactive and multimedia applications that have demanding delay and bandwidth requirements. We discuss how current research into congestion control has uncovered that best-effort networks, with just a few modifications to the existing equipment, can deliver the performance required for a range of applications. Furthermore, we describe how best-effort networks lead to a pricing mechanism that charges users in accordance to the stress they place on the network.
Improvement of the impact strength of a blend of poly(vinyl chloride) with copolyester thermoplastic elastomer by heat treatment (1976)

Abstract Dynamic mechanical properties and impact strength of a blend of poly(vinyl chloride) with a copolyester thermoplastic elastomer were studied. The microscopic structure of the blend was dependent on the thermal history of the specimen. By an appropriate heat treatment, the blend underwent phase separation with an attendant severalfold increase in room‐temperature impact strength. The mechanism of energy dissipation involves both crazing and shear flow processes.
Adjuvanted Schistosoma mansoni-Cathepsin B With Sulfated Lactosyl Archaeol Archaeosomes or AddaVax™ Provides Protection in a Pre-Clinical Schistosomiasis Model (2020)

Schistosomiasis threatens 800 million people worldwide. Chronic pathology manifests as hepatosplenomegaly, and intestinal schistosomiasis caused by <i>Schistosoma mansoni</i> can lead to liver fibrosis, cirrhosis, and blood in the stool. To assist the only FDA-approved drug, praziquantel, in parasite elimination, the development of a vaccine would be of high value. <i>S. mansoni</i> Cathepsin B (SmCB) is a well-documented vaccine target for intestinal schistosomiasis. Herein, we test the increased efficacy and immunogenicity of SmCB when combined with sulfated lactosyl archaeol (SLA) archaeosomes or AddaVax™ (a squalene based oil-in-water emulsion). Both vaccine formulations resulted in robust humoral and cell mediated immune responses. Impressively, both formulations were able to reduce parasite burden greater than 40% (WHO standard), with AddaVax™ reaching 86.8%. Additionally, SmCB with both adjuvants were able to reduce granuloma size and the amount of larval parasite hatched from feces, which would reduce transmission. Our data support SmCB as a target for <i>S. mansoni</i> vaccination; especially when used in an adjuvanted formulation.
Expression of different Jun and Fos proteins during the G0-to-G1 transition in mouse fibroblasts: in vitro and in vivo associations. (1991)

We have characterized the expression of c-Jun, JunB, JunD, c-Fos, and FosB proteins following serum stimulation of quiescent Swiss 3T3 cells by immunoprecipitation analyses. The synthesis of the three Jun proteins rapidly increases following stimulation, remaining at a significant level for at least 8 h. JunB protein presents the highest expression of all. FosB, like c-Fos, is transiently induced. Pulse-chase experiments show that all of the proteins except JunD are short-lived. We have shown that c-Fos and FosB form complexes in vivo with the different Jun proteins and that JunB complexes are predominant. In vitro association and competition experiments show that the affinities between the different Fos and Jun proteins are similar. This finding, together with the in vivo observations described above, suggests that the proportion of the different Jun/Fos heterodimers is governed by the concentration of the different components. The Fos and Jun proteins are phosphoproteins, and some remain relatively highly phosphorylated in their heterodimeric form.
Hyperpolarized C‐13 spectroscopic imaging of the TRAMP mouse at 3T—Initial experience (2007)

The transgenic adenocarcinoma of mouse prostate (TRAMP) mouse is a well-studied murine model of prostate cancer with histopathology and disease progression that mimic the human disease. To investigate differences in cellular bioenergetics between normal prostate epithelial cells and prostate tumor cells, in vivo MR spectroscopic (MRS) studies with non-proton nuclei, such as (13)C, in the TRAMP model would be extremely useful. The recent development of a method for retaining dynamic nuclear polarization (DNP) in solution permits high signal-to-noise ratio (SNR) (13)C MRI or MRSI data to be obtained following injection of a hyperpolarized (13)C agent. In this transgenic mouse study, this method was applied using a double spin-echo (DSE) pulse sequence with a small-tip-angle excitation RF pulse, hyperbolic-secant refocusing pulses, and a flyback echo-planar readout trajectory for fast (10-14 s) MRSI of (13)C pyruvate (pyr) and its metabolic products at 0.135 cm(3) nominal spatial resolution. Elevated (13)C lactate (lac) was observed in both primary and metastatic tumors, demonstrating the feasibility of studying cellular bioenergetics in vivo with DNP hyperpolarized (13)C MRSI.
A survey of code‐based change impact analysis techniques (2012)

SUMMARY Software change impact analysis (CIA) is a technique for identifying the effects of a change, or estimating what needs to be modified to accomplish a change. Since the 1980s, there have been many investigations on CIA, especially for code‐based CIA techniques. However, there have been very few surveys on this topic. This article tries to fill this gap. And 30 papers that provide empirical evaluation on 23 code‐based CIA techniques are identified. Then, data was synthesized against four research questions. The study presents a comparative framework including seven properties, which characterize the CIA techniques, and identifies key applications of CIA techniques in software maintenance. In addition, the need for further research is also presented in the following areas: evaluating existing CIA techniques and proposing new CIA techniques under the proposed framework, developing more mature tools to support CIA, comparing current CIA techniques empirically with unified metrics and common benchmarks, and applying the CIA more extensively and effectively in the software maintenance phase.

Practice Patterns in Benign Prostatic Hyperplasia Surgical Therapy: The Dramatic Increase in Minimally Invasive Technologies (2008)

The increase of total benign prostatic hyperplasia procedure rate was driven by a marked increase in minimally invasive surgical treatment and a continuing decrease of transurethral prostate resection. Differences in the use of minimally invasive surgical treatment across age and racial groups persisted. This dramatic change in the pattern of benign prostatic hyperplasia surgical treatment may have a profound impact on health care expenditures and outcomes, and requires further investigation.
Orally administered<i>lactobacillus</i>strains differentially affect the direction and efficacy of the immune response (1998)

In mice, strain dependent cytokine production profiles are induced after oral administration of Lactobacillus. Such a cytokine profile seems to determine the direction and efficacy of the humoral response. In SJL mice lactobacilli are able to enhance or inhibit the development of disease after induction of experimental autoimmune encephalomyelitis (EAE). Immuno-histochemical analysis of cytokine profiles showed that differential modulation is obtained dependent on the Lactobacillus strain applied. Serum antibody responses to i.p. immunisation with chicken gamma globulin in BALB/c mice are also modulated by oral application of Lactobacillus. Lactobacilli are now being developed as safe live antigen carriers for application in vaccine technology, but also for the excretion of autoantigens in order to induce tolerance. The findings of this study imply that by proper strain selection the direction of the response can be influenced by the induction of a specific cytokine profile.
