A LC quadrature VCO with wide tuning range for TRPC-UWB application in 0.13-&#x00B5;m CMOS (2014)

This paper presents a wideband LC quadrature voltage controlled oscillator (VCO) for novel TRPC-UWB transceiver in 0.13 μm CMOS technology. Based on series coupling structure, and through combining the advanced switched capacitor and MOS varactor techniques, this QVCO's continuous frequency tuning range covers from 5.05 to 5.84 GHz. The measured phase noise at 1 MHz offset from a 5.1 GHz carrier achieves -116.46 dBc/Hz, corresponding to a state of art figure of merit (FoM) at 180.2 dB/Hz. The maximum measured phase error for QVCO over the entire tuning range is below 1.8°.
Mineralogical Changes of a Well Cement in Various H2S-CO2(-Brine) Fluids at High Pressure and Temperature (2007)

The reactivity of a crushed well cement in contact with (1) a brine with dissolved H2S-CO2; (2) a dry H2S-CO2 supercritical phase; (3) a two-phase fluid associating a brine with dissolved H2S-CO2 and a H2S-CO2 supercritical phase was investigated in batch experiments at 500 bar and 120, 200 degrees C. All of the experiments showed that following 15-60 days cement carbonation occurred. The H2S reactivity with cement is limited since it only transformed the ferrites (minor phases) by sulfidation. It appeared that the primary parameter controlling the degree of carbonation (i.e., the rate of calcium carbonates precipitation and CSH (Calcium Silicate Hydrates) decalcification) is the physical state of the fluid phase contacting the minerals. The carbonation degree is complete when the minerals contact at least the dry H2S-CO2 supercritical phase and partial when they contactthe brine with dissolved H2S-CO2. Aragonite (calcium carbonate polymorph) precipitated specifically within the dry H2S-CO2 supercritical phase. CSH cristallinity is improved by partial carbonation while CSH are amorphized by complete carbonation. However, the features evidenced in this study cannot be directly related to effective features of cement as a monolith. Further studies involving cement as a monolith are necessary to ascertain textural, petrophysical, and mechanical evolution of cement.
Epoxy and hyperbranched polymer blends: Morphology and free volume (2010)

Abstract In this work, the phase separation of an epoxy‐functionalized hyperbranched polymer (HBP) in a blend with a conventional epoxy resin is examined. Morphology development with the advancement of curing reaction was investigated by hot‐stage polarized optical microscope, where it was found that HBP is miscible in epoxy resin solvent at 120°C and undergoes phase separation during the curing reaction, leading to a two‐phase microstructure which maintains a dispersed morphology up to 20 wt % HBP. The degree of phase separation and morphology were also investigated using differential scanning calorimetry, and the resultant microstructure was confirmed by atomic force microscopy. The epoxy/HBP blends were characterized by positron annihilation lifetime spectroscopy for their free volume characteristics where behavior typical of miscible blends was seen, likely due to chemical bonding between the two phases. © 2010 Wiley Periodicals, Inc.

Concurrent deletion of 16q23 and PTEN is an independent prognostic feature in prostate cancer (2015)

The deletion of 16q23-q24 belongs to the most frequent chromosomal changes in prostate cancer, but the clinical consequences of this alteration have not been studied in detail. We performed fluorescence in situ hybridization analysis using a 16q23 probe in more than 7,400 prostate cancers with clinical follow-up data assembled in a tissue microarray format. Chromosome 16q deletion was found in 21% of cancers, and was linked to advanced tumor stage, high Gleason grade, accelerated cell proliferation, the presence of lymph node metastases (p < 0.0001 each) and positive surgical margin (p = 0.0004). 16q Deletion was more frequent in ERG fusion-positive (27%) as compared to ERG fusion-negative cancers (16%, p < 0.0001), and was linked to other ERG-associated deletions including phosphatase and tensin homolog (PTEN) (p < 0.0001) and 3p13 (p = 0.0303). In univariate analysis, the deletion of 16q was linked to early biochemical recurrence independently from the ERG status (p < 0.0001). Tumors with codeletions of 16q and PTEN had a worse prognosis (p = 0.0199) than those with PTEN or the deletion of 16q alone. Multivariate modeling revealed that the prognostic value of 16q/PTEN deletion patterns was independent from the established prognostic factors. In summary, the results of our study demonstrate that the deletion of 16q and PTEN cooperatively drives prostate cancer progression, and suggests that deletion analysis of 16q and PTEN could be of important clinical value particularly for preoperative risk assessment of the clinically most challenging group of low- and intermediated grade prostate cancers.
Broadband staircase quantum well infrared photodetector: working in long wavelength infrared range (LWIR) (2007)

Abstract We present a theoretical investigation of a staircase‐like quantum well infrared photodetector (QWIP). It detects wavelength between 7.6 μm and 13.5 μm range at an applied electric field of F = 1.9x10 4 V/cm at 77 K. The dark current density was found to be around 2x10 –7 A/cm 2 at operating bias, which is lower than the conventional QWIPs in the literature. (© 2007 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
The Forgotten Driving Forces in Right Heart Failure: New Concept and Device (2009)

Feasibility and effectiveness of posaconazole prophylaxis in combination with micafungin bridging for patients undergoing allogeneic stem cell transplantation: A 6‐yr analysis from the cologne cohort for neutropenic patients (2014)

Our results suggest that both prophylactic regimens, POS and POS-MIC are feasible, safe and effective. Our data suggest that bridging with intravenous micafungin could indeed improve exposure to antifungal prophylaxis, which may explain the reduced incidence of pneumonia and IFD in the bridging group.
Semantics and CBIR (2008)

Medical CBIR (content-based image retrieval) applications pose unique challenges but at the same time offer many new opportunities. On one hand, while one can easily understand news or sports videos, a medical image is often completely incomprehensible to untrained eyes. On the other hand, semantics in the medical domain is much better defined and there is a vast accumulation of formal knowledge representations that could be exploited to support semantic search for any specialty areas in medicine.In this paper, however, we will not dwell on any one particular specialty area, but rather address the question of how to support scalable semantic search across the whole of medical CBIR field: what are the advantages to take and gaps to fill, what are the key enabling technologies, and the critical success factor from an industrial point of view.In terms of enabling technologies, we discuss three aspects: 1. anatomical, disease, and contextual semantics, and their representations using ontologies; 2. scalable image analysis and tagging algorithms; and 3. ontological reasoning and its role in guiding and improving image analysis and retrieval.More specifically, for ontological representation of medical imaging semantics, we discuss the potential use of FMA, RadLex, ICD, and AIM. For scalable image analysis we present a learning-based anatomy detection and segmentation framework using distribution-free priors. It is easily adaptable to different anatomies and different imaging modalities.
Avaliação da resistência a Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) e Euxesta sp. (Diptera: Otitidae) em linhagens de milho-doce (1994)

Sixteen tines of sweet com were evaluated for resistance to Helicoverpa zea (Boddie) and Euxesta sp. Artificial and natural infestation of H. zea (Boddie) were used. The tines DCOl and DC03 were resistant to both pests. No difference was observed between artificial and natural infestation.
Compression of Neural Machine Translation Models via Pruning (2016)

Neural Machine Translation (NMT), like many other deep learning domains, typically suffers from over-parameterization, resulting in large storage sizes. This paper examines three simple magnitude-based pruning schemes to compress NMT models, namely class-blind, class-uniform, and class-distribution, which differ in terms of how pruning thresholds are computed for the different classes of weights in the NMT architecture. We demonstrate the efficacy of weight pruning as a compression technique for a state-of-the-art NMT system. We show that an NMT model with over 200 million parameters can be pruned by 40% with very little performance loss as measured on the WMT'14 English-German translation task. This sheds light on the distribution of redundancy in the NMT architecture. Our main result is that with retraining, we can recover and even surpass the original performance with an 80%-pruned model.
The Electricity of Touch: Detection and measurement of cardiac energy exchange between people (2018)

The idea that an energy exchange of some type occurs between individuals is a central theme in many healing techniques. This concept has often been disputed by Western science due to the lack of a plausible mechanism to explain the nature of this energy or how it could affect or facilitate the healing process. The fact that the heart generates the strongest electromagnetic field produced by the body, coupled with the recent discovery that this field becomes more coherent as the individual shifts to a sincerely loving or caring state prompted us to investigate the possibility that the field generated by the heart may significantly contribute to this energy exchange. We present a sampling of results which provide intriguing evidence that an exchange of electromagnetic energy produced by the heart occurs when people touch or are in proximity. Signal averaging techniques are used to show that one’s electrocardiogram (ECG) signal is registered in another person’s electroencephalogram (EEG) and elsewhere on the other person’s body. While this signal is strongest when people are in contact, it is still detectable when subjects are in proximity without contact. This study represents one of the first successful attempts to directly measure an energy exchange between people, and provides a solid, testable theory to explain the observed effects of many healing modalities that are based upon the assumption that an energy exchange takes place. Nonlinear stochastic resonance is discussed as a mechanism by which weak, coherent electromagnetic fields, such as those generated by the heart of an individual in a caring state, may be detected and amplified by biological tissue, and potentially produce measurable effects in living systems. One implication is that the effects of therapeutic techniques involving contact or proximity between practitioner and patient could be amplified by practitioners consciously adopting a sincere caring attitude, and thus introducing increased coherence into their cardiac field.

VIBRATED SIEVING SHARES FOR POTATO HARVESTING (1986)

The design and performance of several vibrating share models are presented and theproblems with each model are discussed. The shares were assembled on aprototype potato harvester for evaluation. Each model successfully enhanced soil sieving but created problems with soil flow. The last vibrating share model built was the most complex and was the final attempt to improve soil flow. The draft force and soil sieving capability of this model was compared to that of a plain share to evaluate the share performance. The vibrating share model performance was also compared to that of the oscillating share by evaluating the potato damage level of each.
Cofactor Selectivity in Methylmalonyl Coenzyme A Mutase, a Model Cobamide-Dependent Enzyme (2019)

Cobamides, a uniquely diverse family of enzyme cofactors related to vitamin B<sub>12</sub>, are produced exclusively by bacteria and archaea but used in all domains of life. While it is widely accepted that cobamide-dependent organisms require specific cobamides for their metabolism, the biochemical mechanisms that make cobamides functionally distinct are largely unknown. Here, we examine the effects of cobamide structural variation on a model cobamide-dependent enzyme, methylmalonyl coenzyme A (CoA) mutase (MCM). The <i>in vitro</i> binding affinity of MCM for cobamides can be dramatically influenced by small changes in the structure of the lower ligand of the cobamide, and binding selectivity differs between bacterial orthologs of MCM. In contrast, variations in the lower ligand have minor effects on MCM catalysis. Bacterial growth assays demonstrate that cobamide requirements of MCM <i>in vitro</i> largely correlate with <i>in vivo</i> cobamide dependence. This result underscores the importance of enzyme selectivity in the cobamide-dependent physiology of bacteria.<b>IMPORTANCE</b> Cobamides, including vitamin B<sub>12</sub>, are enzyme cofactors used by organisms in all domains of life. Cobamides are structurally diverse, and microbial growth and metabolism vary based on cobamide structure. Understanding cobamide preference in microorganisms is important given that cobamides are widely used and appear to mediate microbial interactions in host-associated and aquatic environments. Until now, the biochemical basis for cobamide preferences was largely unknown. In this study, we analyzed the effects of the structural diversity of cobamides on a model cobamide-dependent enzyme, methylmalonyl-CoA mutase (MCM). We found that very small changes in cobamide structure could dramatically affect the binding affinity of cobamides to MCM. Strikingly, cobamide-dependent growth of a model bacterium, <i>Sinorhizobium meliloti</i>, largely correlated with the cofactor binding selectivity of <i>S. meliloti</i> MCM, emphasizing the importance of cobamide-dependent enzyme selectivity in bacterial growth and cobamide-mediated microbial interactions.
Shock Tube Ignition Delay Times and Modeling of Jet Fuel Mixtures (2006)

Ignition delay times were measured for stoichiometric jet fuel mixtures (Jet-A and JP-8) in air behind reflected shock waves in a heated shock tube. Reflected shock conditions spanned the following ranges: temperature 875 to 1220 K, pressure 18 to 36 atm, and an equivalence ratio of 1.0. Ignition times were measured using sidewall-mounted piezo-electric transducers and confirmed at the same location with OH* emission measurements at 306 nm. The shock tube and mixing assembly were heated to 100 and 125 C, respectively, to prevent condensation of the lower vapor pressure/higher boiling point components of the fuel. The Jet-A/JP-8 results have very low scatter and are in excellent agreement with the limited previous shock tube measurements. To the best of our knowledge, we report the first shock tube ignition time data for JP-8. Although JP-8 composition is slightly different from Jet-A, their ignition times are in close agreement. The experimental results were compared with model calculations of ignition time using the models of Ranzi et al. (2005) and Zhang et al. (2005), applied to a jet fuel surrogate composition proposed by Violi et al. (2002).

A system composed of an MPEG-2 video transcoder to change bitrate, frame rate and frame size and a cross layer controller gathering information from physical, MAC, driver, and RTCP layers, calculating instantaneous network throughput, to optimize real-time adaptive A/V streaming over IEEE 802.11 is presented.
<title>Error dispersion algorithms to improve the precision of angle detection for the optical encoder</title> (2000)

We have applied the interference fringe scanning algorithms that are used in interference fringe analysis to an optical encoder as angle detection algorithms, in order to disperse the influence of sinusoid wave distortion from the encoder's photo detector. We also evaluated these algorithms with the analytical system and techniques for obtaining the same output signal as that of the actual encoder, by using image data on light intensity as the light permeates the slit disk of the encoder. As a result, we obtained about twice the angle precision by applying the algorithms to the optical encoder.
Effects of sodium valproate on cisplatin-induced acute kidney injury (2022)

OBJECTIVE: Cisplatin-induced acute kidney injury (AKI) is well known, and the nephrotoxicity of cisplatin restricts its clinical application. Currently, there are no drugs are recommended for the prevention of cisplatin-induced AKI. Forced hydration and diuresis may partially prevent nephrotoxicity of cisplatin, but it is still difficult to entirely prevent kidney injury. Thus, establishment of a new preventive method against cisplatin-induced AKI is required. Therefore, in this study, the purpose of this study was to clarify the efficacy of sodium valproate in cisplatin-induced AKI.
Immunohistochemical localization of eotaxin immunoreactivity in nasal polyps (2004)

Eotaxin is a C-C chemokine that acts to selectively induce local accumulation of eosinophils and basophils. Eotaxin is also believed to be involved in the infiltration of eosinophils in the nasal polyps of patients with chronic sinusitis. However, only a few studies on eotaxin in nasal polyps have been performed. In this study, we investigated the localization of eotaxin in human nasal polyps and the identification of eotaxin-positive cells using immunohistochemistry. The distribution of eotaxin immunoreactivity in the nasal polyps of patients with chronic sinusitis was found to almost coincide with the presence of eosinophils. Eotaxin immunoreactivity was also detected in some vascular endothelial cells. These findings suggest that eotaxin is produced by eosinophils and vascular endothelial cells in nasal polyps and is involved in the accumulation of eosinophils in nasal polyps.
Fine‐grained recognition of maritime vessels and land vehicles by deep feature embedding (2018)

Recent advances in large‐scale image and video analysis have empowered the potential capabilities of visual surveillance systems. In particular, deep learning‐based approaches bring in substantial benefits in solving certain computer vision problems such as fine‐grained object recognition. Here, the authors mainly concentrate on classification and identification of maritime vessels and land vehicles, which are the key constituents of visual surveillance systems. Employing publicly available data sets for maritime vessels and land vehicles, the authors aim to improve visual recognition. Specifically, the authors focus on five tasks regarding visual recognition; coarse‐grained classification, fine‐grained classification, coarse‐grained retrieval, fine‐grained retrieval, and verification. To increase the performance in these tasks, the authors utilise a multi‐task learning framework and present a novel loss function which simultaneously considers deep feature learning and classification by exploiting the available hierarchical labels of individual samples and the global statistics of distances between the data pairs. The authors observe that the proposed multi‐task learning model improves the fine‐grained recognition performance on MARVEL and Stanford Cars data sets, compared to training of a model targeting a single recognition task.
Consequences of Immunodominant Epitope Deletion for Minor Influenza Virus-Specific CD8+-T-Cell Responses (2005)

The extent to which CD8+ T cells specific for other antigens expand to compensate for the mutational loss of the prominent DbNP366 and DbPA224 epitopes has been investigated using H1N1 and H3N2 influenza A viruses modified by reverse genetics. Significantly increased numbers of CD8+ KbPB1(703)+, CD8+ KbNS2(114)+, and CD8+ DbPB1-F2(62)+ T cells were found in the spleen and in the inflammatory population recovered by bronchoalveolar lavage from mice that were first given the -NP-PA H1N1 virus intraperitoneally and then challenged intranasally with the homologous H3N2 virus. The effect was less consistent when this prime-boost protocol was reversed. Also, though the quality of the response measured by cytokine staining showed some evidence of modification when these minor CD8+-T-cell populations were forced to play a more prominent part, the effects were relatively small and no consistent pattern emerged. The magnitude of the enhanced clonal expansion following secondary challenge suggested that the prime-boost with the -NP-PA viruses gave a response overall that was little different in magnitude from that following comparable exposure to the unmanipulated viruses. This was indeed shown to be the case when the total response was measured by ELISPOT analysis with virus-infected cells as stimulators. More surprisingly, the same effect was seen following primary challenge, though individual analysis of the CD8+ KbPB1(703)+, CD8+ KbNS2(114)+, and CD8+ DbPB1-F2(62)+ sets gave no indication of compensatory expansion. A possible explanation is that novel, as yet undetected epitopes emerge following primary exposure to the -NP-PA deletion viruses. These findings have implications for both natural infections and vaccines.
