A Soft Sensing Prediction Model of Superheat Degree in the Aluminum Electrolysis Production (2018)

Aluminum alloy is widely used in transportation, catering, industry, sports, health and other fields, because of their excellent high specific strength and corrosion resistance. Aluminum industry has been an important mainstay industry of a national economy. In the process of electrolytic aluminum, the superheat degree is a very important production target. When an electrolysis cell is working in the appropriate superheat degree state, the life of cell is prolonged and the amounts of aluminum released will enhanced. However, to measure the superheat degree is very difficult and the measured results cannot timely feedback to the process of production. To address the problem, a soft sensing prediction model of superheat degree is proposed in this paper, in which some new concepts such as the decay function of data weight, the credibility of a rule and the rule tree are introduced. Basically speaking, the processing of the soft sensing prediction model is mainly based on the rough set data analysis method and a tree data structure. The static rules are obtained from the history data by using the attribute reduction and value reduction method in the rough sets. The rule tree is updated timely based on the incremental data set accordingly. The effectiveness of the proposed model is verified with the aluminum production data provided by Shandong Weiqiao Aluminum Electrolysis limited company in China.
EVALUATION OF TWO TOXOPLASMA GONDII SEROLOGIC TESTS USED IN A SEROSURVEY OF DOMESTIC CATS IN CALIFORNIA (2007)

We evaluated the sensitivity (Se) and specificity (Sp) of an IgG enzyme-linked immunosorbent assay (ELISA) and IgG indirect fluorescent antibody test (IFAT) for detection of Toxoplasma gondii-specific antibodies in sera from 2 cat populations using a Bayesian approach. Accounting for test covariance, the Se and Sp of the IgG ELISA were estimated to be 92.6% and 96.5%, and those of the IgG IFAT were 81.0% and 93.8%, respectively. Both tests performed poorly in cats experimentally coinfected with feline immunodeficiency virus and T. gondii. Excluding this group, Se and Sp of the ELISA were virtually unchanged (92.3% and 96.4%, respectively), whereas the IFAT Se improved to 94.2% and Sp remained stable at 93.7%. These tests and an IgM ELISA were applied to 123 cat sera from the Morro Bay area, California, where high morbidity and mortality attributable to toxoplasmosis have been detected in southern sea otters. Age-adjusted IgG seroprevalence in this population was estimated to be 29.6%, and it did not differ between owned and unowned cats. Accounting for Se, Sp, and test covariances, age-adjusted seroprevalence was 45.0%. The odds for T. gondii seropositivity were 12.3-fold higher for cats aged >12 mo compared with cats aged <6 mo.
Catchlike property of human muscle during isovelocity movements (1996)

This study examined the catchlike property of skeletal muscle during eccentric and concentric isovelocity contractions of fresh and fatigued quadriceps femoris muscles of 10 healthy subjects. During concentric contractions of fresh muscles, stimulation trains that elicited a catchlike response (CITs) produced greater force outputs and rates of rise force than comparable constant-frequency trains. These enhancements became more pronounced during fatigue. CITs were less effective in enhancing forces during eccentric contractions but did improve the rates of rise of force. Overall, the CIT that produced the greatest augmentation had a 5-ms initial interpulse interval. Proposed mechanisms for the catchlike property involve enhanced muscle stiffness for more efficient transmission of tension and increased calcium release. These results suggest that stimulation trains that take advantage of the catchlike property of skeletal muscle may be helpful during clinical applications where neuromuscular electrical stimulation is used to restore function in patients with damaged central nervous systems.
A Rare Case of Metastatic Merkel Cell Carcinoma to the Stomach and Pancreas Presenting With Upper Gastrointestinal Bleeding and Obstructive Jaundice (2021)

Merkel cell carcinoma (MCC) is a rare and aggressive primary neuroendocrine tumor of the skin. Gastrointestinal (GI) metastasis in MCC is uncommon. We present a case of MCC with metastasis to the stomach, duodenum, and pancreas presenting with melena and obstructive jaundice. A large, bleeding metastatic mass was identified in the duodenum. Hemostasis was achieved with coil embolization. Endoscopic retrograde cholangiopancreatography with stenting of the common bile duct was performed to relieve the obstruction. Close surveillance with positron emission tomography/computed tomography scan and possible GI endoscopy should be performed in cases with distant metastasis to identify and treat early GI tract lesions.
Beamforming for broadband constant beamwidth through FIR filter and DSP implementation (1998)

The paper presents a method to design a beamformer for broadband constant beamwidth. This is important in sonar systems for sea bottom observation and classification applications. For a given frequency band, a number of frequency points are chosen to represent the response. For each frequency point, a beamforming weighting vector can be deduced to satisfy a given beamwidth requirement by existing methods, for example, Chebyshev shielding coefficients can be deduced for a linear array. For a broadband array of N elements, a N*M matrix can be obtained if M frequency points are chosen. Each row of the matrix represents a frequency response of an array element, which can be satistied by a FIR filter designed by model-reference adaptive techniques. The sum of outputs from a bank of N FIR filters provides a beamformed output and so it is very handy to be implemented by DSP hardware. A design example shows that the results are satisfactory.
Home-based monitoring of cardiac patients (2002)

The paper describes an ongoing effort towards the design of systems for home based monitoring of cardiac patients. The goal is to develop systems that could support early discharge of cardiac patients and enable their home based recuperation. Such systems could act as a virtual extension of the ICU/CCU systems in the hospital, enabling physicians to monitor patients at home, and giving them the ability to discharge patients earlier while continuing to monitor their recuperation progress. This concept could result in direct health care cost savings and improvement in the quality of medical care, especially in rural areas with limited access to cardiologists. Our first step towards this goal is a system that can send cardiac data from the patient to the physician via the Internet. The physician can perform data analysis and send reports back to the patient over the Internet. In order to provide a truly home based monitoring system, we plan to add to the current system the ability to transmit real time cardiac and blood pressure events over cellular telephone networks.
Structure and zero-dimensional polariton spectrum of natural defects in GaAs/AlAs microcavities (2012)

We present a correlative study of structural and optical properties of natural defects in planar semiconductor microcavities grown by molecular beam epitaxy, which are showing a localized polariton spectrum as reported in Zajac et al. [Phys. Rev. B 85, 165309 (2012)]. The three-dimensional spatial structure of the defects was studied using combined focused ion beam (FIB) and scanning electron microscopy (SEM). We find that the defects originate from a local increase of a GaAs layer thickness. Modulation heights of up to 140 nm for oval defects and 90 nm for round defects are found, while the lateral extension is about 2 $\ensuremath{\mu}$m for oval and 4 $\ensuremath{\mu}$m for round defects. The GaAs thickness increase is attributed to a Ga droplet deposited during growth due to Ga cell spitting. Following the droplet deposition, the thickness modulation expands laterally while reducing its height, yielding oval to round mounds of the interfaces and the surface. With increasing growth temperature, the ellipticity of the mounds is decreasing and their size is increasing. This suggests that the expansion is related to the surface mobility of Ga, which, with increasing temperature, is increasing and reducing its anisotropy between the $[110]$ and $[1\overline{1}0]$ crystallographic directions. Comprehensive data consisting of surface profiles of defects measured using differential interference contrast microscopy, volume information obtained using FIB/SEM, and characterization of the resulting confined polariton spectrum are presented.

Likelihood-based docking of models into cryo-EM maps (2022)

Abstract Optimized docking of models into cryo-EM maps requires exploiting an understanding of the signal expected in the data to minimize the calculation time while maintaining sufficient signal. The likelihood-based rotation function used in crystallography can be employed to establish plausible orientations in a docking search. A phased likelihood translation function yields scores for the placement and rigid-body refinement of oriented models. Optimised strategies for choices of the resolution of data from the cryo-EM maps to use in the calculations and the size of search volumes are based on expected log-likelihood-gain scores, computed in advance of the search calculation. Tests demonstrate that the new procedure is fast, robust and effective at placing models into even challenging cryo-EM maps. Synopsis Exploiting analogies to crystallographic molecular replacement, a strategy for docking into cryo-EM maps is informed by calculations of expected log-likelihood-gain scores.
Une approche de benchmarking des pratiques de gestion basées sur un middleware JMX pour les services et les applications (2006)

Les communautés systèmes, systèmes distribués et applications réparties ont développé des suites de benchmarking pour un nombre considérable de leurs applications. Ces suites sont centrées sur les calculs intensifs, serveurs web et bases de données. Cependant, dans le monde de la gestion d'applications et de services, des plates-formes de benchmarking sont rares et même absentes pour des technologies de gestion comme JMX, le standard pour la gestion des applications et des services du monde Java. Cette absence de plates-formes de em benchmarking pour les systèmes de gestion est acceptable pour des systèmes gérés avec des ressources considérables, mais l'est moins pour des systèmes gérés ayant des ressources contraintes. Nous proposons dans cet article une approche de benchmarking du middleware JMX basée sur son évaluation selon différentes pratiques de gestion. Dans ce but, nous avons identifié et isolé les paramètres relatifs à chaque pratique sous test ainsi que la définition de métriques d'évaluation de leurs performances.
Serum albumin is a specific inhibitor of apoptosis in human endothelial cells (1996)

Excess blood vessels are removed by apoptosis of endothelial cells, however, the signals responsible for this have not been defined. Apoptosis of cultured human umbilical vein endothelial cells is induced by deprivation of serum or adhesion. In this paper, apoptosis in human umbilical vein and microvascular endothelium was induced by deprivation of serum and or adhesion. Apoptosis was confirmed on the basis of morphology, ultrastructure and internucleosomal cleavage of DNA. Loss of endothelial adhesion was found to be an early event in cultured endothelial cell apoptosis and was exploited to quantitate apoptosis. The effect of: bovine serum albumin; human serum albumin; recombinant human albumin; dithiothreitol reduced human and bovine albumin; CNBr treated human and bovine albumin as well as ovalbumin upon endothelial apoptosis was determined. Native bovine and human albumin as well as recombinant human material inhibited apoptosis at physiological concentrations with identical dose response curves in both umbilical vein and microvascular cells. Dithiothreitol treatment destroyed all protective activity while bovine but not human albumin was partially inactivated by CNBr treatment. The unrelated protein ovalbumin was not protective. Albumin did not inhibit apoptosis if cells were also deprived of adhesion. The data suggest that albumin is a specific inhibitor of human endothelial apoptosis but does not protect cells also deprived of adhesion. Reduced supply of albumin to endothelium in poorly perfused blood vessels may provide a mechanism for the removal of excess blood vessels in remodelling tissues. Also, the failure of albumin to protect endothelial cells deprived of adhesion from apoptosis may reflect the need to remove potentially micro-embolic cells detached due to trauma.
Community Variability of Bacteria in Alpine Snow (Mont Blanc) Containing Saharan Dust Deposition and Their Snow Colonisation Potential (2011)

Microorganisms uplifted during dust storms survive long-range transport in the atmosphere and could colonize high-altitude snow. Bacterial communities in alpine snow on a Mont Blanc glacier, associated with four depositions of Saharan dust during the period 2006-2009, were studied using 16S rRNA gene sequencing and flow cytometry. Also, sand from the Tunisian Sahara, Saharan dust collected in Grenoble and Mont Blanc snow containing no Saharan dust (one sample of each) were analyzed. The bacterial community composition varied significantly in snow containing four dust depositions over a 3-year period. Out of 61 phylotypes recovered from dusty snow, only three phylotypes were detected in more than one sample. Overall, 15 phylotypes were recognized as potential snow colonizers. For snow samples, these phylotypes belonged to Actinobacteria, Proteobacteria and Cyanobacteria, while for Saharan sand/dust samples they belonged to Actinobacteria, Bacteroidetes, Deinococcus-Thermus and Proteobacteria. Thus, regardless of the time-scale, Saharan dust events can bring different microbiota with no common species set to alpine glaciers. This seems to be defined more by event peculiarities and aeolian transport conditions than by the bacterial load from the original dust source.
A Fluorimetric Method for the Determination of Dopamine (3‐Hydroxytyramine.) (1958)

Summary. A fluorimetric method for the determination of dopamine is described. The principle is similar to that employed in the tri‐hydroxyindole method for estimating adrenaline and noradrenaline. Utilizing differences in fluorescence characteristics at pH about 5.3, microquantities of dopainine can be determined in the presence of at least equal amounts of adrenaline or noradrenaline.

Pyrolysis of Mixed Solid Food, Paper, and Packaging Wastes (2008)

&lt;div class="htmlview paragraph"&gt;Pyrolysis is a very versatile waste processing technology which can be tailored to produce a variety of solid, liquid and/or gaseous products. The pyrolysis processing of pure and mixed solid waste streams has been under investigation for several decades for terrestrial use and a few commercial units have been built for niche applications. Pyrolysis has more recently been considered for the processing of mixed solid wastes in space. While pyrolysis units can easily handle mixed solid waste streams, the dependence of the pyrolysis product distribution on the component composition is not well known. It is often assumed that the waste components (e.g., food, paper, plastic) behave independently, but this is a generalization that can usually only be applied to the overall weight loss and not always to the yields of individual gas species. The current paper will present results on pyrolysis of various mixtures of plastic (polyethylene), food (composite of 40% assorted dried food, 30% flour, 10% milk powder, 7% egg powder, 4% potato powder, 3% gluten, 3% corn starch, 3% sugar), and paper (cellulose). In addition to the model mixed food waste sample, additional runs were done with actual restaurant food waste after it was dehydrated. The paper will include results for major product yields (char, gas, water + oil, carbon) as well as the gas composition (H&lt;sub&gt;2&lt;/sub&gt;, CO&lt;sub&gt;2&lt;/sub&gt;, CO, CH&lt;sub&gt;4&lt;/sub&gt;, C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;4&lt;/sub&gt;, and NH&lt;sub&gt;3&lt;/sub&gt;), and the char composition and char reactivity.&lt;/div&gt;
A Comparison of MMPI Personality Data and Frontalis Electromyographic Readings in Two Groups of Daily Headache Sufferers (1983)

SYNOPSIS Forty, daily headache patients were divided into two diagnostic categories ‐ chronic scalp muscle contraction headache alone and chronic scalp muscle contraction headache associated with analgesic rebound. Electromyographic readings from the frontalis muscle and personality data from selected scales of the MMPI served as comparison variables between the two groups. A second part of the study divided these headache patients into a high muscle tension group (the ten patients with the highest frontalis muscle readings) and a low muscle tension group (the ten patients with the lowest frontalis reading). This division was made regardless of the original group membership. Personality data in these two groups were compared. Results provided information regarding the relationship between the amount of medication taken by the patient, their degree of psychopathology as measured by the MMPI, and the amount of muscle tension recorded. Suggestions for future research projects were made.
Formation of carbocations from bornan-2-exo-ol and its derivatives and their reactions with some nucleophiles (1975)

The reactions of bornan-2-exo-yl chloride and its isomers with carbon monoxide, acetonitrile, and water in antimony pentachloride–sulphur dioxide give bornan-2-exo-yl derivatives selectively. The reactions of bornan-2-exo-ol and its isomers with thionyl chloride showed marked dependence on the solvent used. The reactions of the alcohols with sulphuryl chloride are also reported.
Complex soliton-like pattern generation in Potassium Niobate due to noisy, high intensity, input beams (2003)

We report the generation of complex soliton-like patterns in noncritically-phase-matched potassium niobate which occur in random spatial patterns from shot-to-shot. Up to five spots have been generated at input intensities of 10's GW/cm2, many times the single soliton threshold. The mechanism which leads to the symmetry breaking required for the complex patterns is interpreted to be random noise imprinted on the input light.

Novel Shape‐Memory Polymer with Two Transition Temperatures (2005)

Abstract Summary: This communication describes a novel kind of PMMA‐PEG semi‐interpenetrating network (semi‐IPN) which shows excellent shape‐memory behavior at two transition temperatures, the T m of the PEG crystal and the T g of the semi‐IPN. Based on a reversible order‐disorder transition of the crystals below and above the T m of PEG, and the large difference in storage modulus below and above the T g of the semi‐IPN, the polymer has a recovery ratio of 91 and 99%, respectively.

.beta.-NGF-endopeptidase: structure and activity of a kallikrein encoded by the gene mGK-22 (1991)

Mouse nerve growth factor (NGF) is cleaved at a histidine-methionine bond to release an NH2-terminal octapeptide (NGF1-8). The enzyme responsible, beta-NGF-endopeptidase, is structurally and functionally similar to gamma-NGF and epidermal growth factor-binding protein (EGF-BP) and cleaves mouse low molecular weight kininogen to produce bradykinin-like activity. These data have suggested that, like gamma-NGF and EGF-BP, beta-NGF-endopeptidase is a mouse glandular kallikrein. Evidence for a physiological role for NGF1-8 encouraged studies to further characterize the structure and function of this enzyme. Purified beta-NGF-endopeptidase migrated as a single band on isoelectric focusing and reducing SDS-polyacrylamide gels. As was expected, it removed NGF1-8 from NGF. Interestingly, enzymatic activity on an artificial substrate, and on NGF, was inhibited by NGF1-8 and by bradykinin. These studies further supported the view that beta-NGF-endopeptidase acts on both NGF and kininogen. The first 30 NH2-terminal amino acids of beta-NGF-endopeptidase were sequenced. This analysis demonstrated that the enzyme is encoded by the gene designated mGK-22 (Evans et al., 1987). The sequence of this gene corresponds to that of EGF-BP type A (Anundi et al., 1982; Drinkwater et al., 1987), and so studies were performed to determine whether or not beta-NGF-endopeptidase participates in EGF complex formation. Chromatographic and kinetic data gave no evidence that beta-NGF-endopeptidase is an EGF-binding protein. Our studies suggest that contamination of high molecular weight (HMW) EGF preparations with beta-NGF-endopeptidase erroneously led to earlier designation of the product of mGK-22 as an EGF-BP.(ABSTRACT TRUNCATED AT 250 WORDS)
