Application of inductively coupled plasma mass spectrometry for total metal determination in silicon-containing solid samples using the microwave-assisted nitric acid–hydrofluoric acid–hydrogen peroxide–boric acid digestion system (1996)

The microwave-assisted conventional HNO3–HF–H2O2–H3BO3 digestion system has been explored for direct ICP-MS analysis of total metals in silicon-containing solid samples. In closed Teflon PFA vessels under microwave heating with temperature/pressure regulation, a 0.25 g portion of sample containing ⩽ 33% silicon was digested in 1.5 ml of HF (48%), 5 ml of concentrated HNO3 and 2 ml of H2O2(30%), followed by a second digestion stage with 12 ml of 5% m/v boric acid. The amount of HF used was approximately twice the stoichiometric requirement for 33% silicon contained in the samples, assuming all silicon exists as silica. The amount of boric acid used was the stoichiometric requirement for the HF added. With a sample dilution factor of 2000 (v/m), the end solution contained ⩽ 0.17% total dissolved solids for ICP-MS analysis. The ICP-MS system was calibrated by the method of external standards prepared in reagent blank solutions with in as the internal standard. The sensitivity of the In signal in a 5–8 h operation was only decreased by 5–10%. Background interferences from the digestion reagents were studied and corrected. The method developed is simple and rugged and suitable for routine analysis of at least 25 elements: Al, Ag, As, Ba, Bi, Cd, Co, Cr, Cu, Fe, Li, Mg, Mn, Mo, Ni, Pb, Sb, Sn, Sr, Th, Ti, Tl, U, V and Zn. The recoveries for most of these elements in standard reference materials including coal fly ash, urban particulate matter, sediment and soil were within 90–110%, and the relative standard deviations were within 5%. The method cannot determine B and is not suitable for Hg determination. The detection limits for Be and Se determination are not adequate.
Promotion and resignation in employee networks (2015)

Enterprises have put more and more emphasis on data analysis so as to obtain effective management advices. Managers and researchers are trying to dig out the major factors that lead to employees' promotion and resignation. Most previous analyses were based on questionnaire survey, which usually consists of a small fraction of samples and contains biases caused by psychological defense. In this paper, we successfully collect a data set consisting of all the employees' work-related interactions (action network, AN for short) and online social connections (social network, SN for short) of a company, which inspires us to reveal the correlations between structural features and employees' career development, namely promotion and resignation. Through statistical analysis and prediction, we show that the structural features of both AN and SN are correlated and predictive to employees' promotion and resignation, and the AN has higher correlation and predictability. More specifically, the in-degree in AN is the most relevant indicator for promotion; while the k-shell index in AN and in-degree in SN are both very predictive to resignation. Our results provide a novel and actionable understanding of enterprise management and suggest that to enhance the interplays among employees, no matter work-related or social interplays, can largely improve the loyalty of employees.

Escherichia coli Expression of Site-Directed Mutants of Cytochrome P450 2B1 from Six Substrate Recognition Sites: Substrate Specificity and Inhibitor Selectivity Studies (1995)

Cytochrome P450 2B1 wild-type and eight site-directed mutations at positions 114, 206, 236, 302, 363, 367, and 478 have been expressed in an Escherichia coli system. Solubilized membrane preparations yielded 100-180 nmol of P450/L of culture. The metabolism of a number of substrates including androstenedione, progesterone, (benzyloxy)resorufin, pentoxyresorufin, and benzphetamine was analyzed. The E. coli-expressed enzymes displayed the same androstenedione metabolite profiles previously observed with a COS cell expression system. Several of the mutants exhibited an increased rate of progesterone hydroxylation, possibly as the result of an enlarged substrate binding pocket and increased D-ring alpha-face binding. (Benzyloxy)resorufin and pentoxyresorufin O-dealkylation by the P450 2B1 mutants exhibited activities ranging from 10% to 99% and 3% to 71% of wild-type, respectively. Interestingly, the Val-363-->Leu mutant showed markedly suppressed pentoxyresorufin but unaltered (benzyloxy)resorufin dealkylase activity. Benzphetamine N-demethylase activities ranged from 28% to 110% of wild-type. Mechanism-based inactivation of the P450 2B1 mutants showed that susceptibility to inactivation by chloramphenicol and D-erythro- and L-threo-chloramphenicol was abolished in the Val-367-->Ala mutant. The Val-363-->Leu mutant was refractory to L-threo-chloramphenicol. Studies of chloramphenicol covalent binding and metabolism by the Val-367-->Ala mutant showed that its resistance to inactivation is largely attributable to an inability to bioactivate the inhibitor. The expression of P450 2B1 wild-type and mutants in E. coli provides an excellent opportunity to study structure/function relationships by site-directed mutagenesis.

Vibration analysis of human tibia: The effect of soft tissue on the output from skin-mounted accelerometers (1984)

The vibration response of bone can be recorded from a skin-mounted accelerometer, but only if it is sufficiently preloaded to overcome the damping effect of the interposed soft tissue. Excessive preload results in distortion of the recorded signal by a high-frequency component which probably originates in the supporting apparatus of the accelerometer. The required preload is proportional to the soft tissue thickness, but for any given soft tissue thickness, the range of allowable preload is fairly wide.
Notes: Branhamaceae fam. nov., a Proposed Family To Accommodate the Genera Branhamella and Moraxella (1991)

The genera assigned to the family Neisseriaceae in 1984 (K. Bøvre, p. 288-290, in N. R. Krieg and J. G. Holt, ed., Bergey’s Manual of Systematic Bacteriology, vol. 1) are now recognized as members of two different groups (the beta and gamma groups) of the class Proteobacteria. DNA base composition data, findings from DNA-mediated transformation to streptomycin resistance, DNA-DNA hybridization, and DNA-rRNA hybridization, and results from electrophoresis of soluble proteins have revealed differences that mandate separation from Neisseria of the three species of “false neisseriae” (Neisseria caviae, Neisseria ovis, and Neisseria cuniculi), and also of the genera Branhamella, Moraxella, and Acinetobacter. Since these organisms must be excluded from the Neisseriaceae, the new family Branhamaceae is proposed to accommodate the genera Branhamella (including the false neisseriae) and Moraxella. This arrangement acknowledges the phylogenetic relationships of these organisms and resolves controversies concerning (i) the recommendation that the genus Moraxella should be divided into the subgenus Moraxella (for rod-shaped organisms) and the subgenus Branhamella (for cocci) and (ii) the taxonomic placement of the false neisseriae. The present evidence does not favor inclusion of the genus Acinetobacter in the family Branhamaceae. The following species are included at this time in the type genus, Branhamella: Branhamella catarrhalis (the type species), Branhamella caviae, Branhamella ovis, and Branhamella cuniculi. The species allocated at this time to the genus Moraxella are Moraxella lacunata (the type species) Moraxella bovis, Moraxella nonliquefaciens, Moraxella osloensis, Moraxella phenylpyruvica, and Moraxella atlantae.
What Are Normal Blood Values for Leukemia in Remission? (1959)

Abstract 1. The values for hemoglobin concentration, total white blood cells, granulocytes, lymphocytes and monocytes at the midpoint of 78 drug-induced remissions in a group of children with acute leukemia have been presented. These values have been compared with those from a group of normal children, and the differences analyzed statistically. 2. Statistical analysis shows that, in general, blood values in remission are reduced by the particular agent employed. White blood cells are more markedly affected than hemoglobin. 3. The effects are essentially the same with 6-M.P. given alone or in combination with azaserine or DON. 4. The reduction in values is greatest with 6-M.P., alone or in combination, less with amethopterin and least with prednisone. 5. The data presented indicate that criteria for complete blood remission should make allowances for the influence of the drug employed.
Synthesis, estrogen receptor binding affinity and biological evaluation of some 2-substituted estrone derivatives. (1997)

This report details the preparation of modified estrogens which are structurally designed to possess estrogenic and/or antiestrogenic activity. The prominent feature of these estrogens is the introduction of a novel side chain in the 2-position of ring A of the steroid nucleus. Their synthesis includes the use of transformations based upon Mannich base chemistry: preparation of the intermediate 2-dimethylamino-methylestrone via aminomethylation of estrone and introduction of various functionalities via reaction of this Mannich base with different reagents. When evaluated for their interaction with the estrogen receptor by competitive binding assays, the tested products were found to be relatively weak competitors at 0 degree C. The uterotrophic and post-coital antifertility assays indicated effects varying in magnitude relative to estradiol. Ethyl[(2'-acetyl-3'-(3-hydroxyestra-17-oxo-1,3,5 (10)-trien-2-yl)]propionate (15) showed uterotrophic and antiimplantation activities of 95% and 20% respectively.
Lock-Based Concurrency Control in Distributed Real-Time Database Systems (1993)

A real-time database system (RTDBS) is designed to provide timely response to the transactions of data-intensive applications. The transactions processed in a RTDBS are associated with real-time constraints typically in the form of deadlines. With the current database technology it is extremely difficult to provide schedules guaranteeing transaction deadlines. This difficulty comes from the unpredictability of transaction response times. Efficient resource scheduling algorithms and concurrency control protocols are required to schedule RTDB transactions so as to maximize the number of satisfied deadlines. In this paper, we describe several distributed, lock-based, real-time concurrency control protocols and report on the relative performance of the protocols in a distributed database environment. The protocols are different in the way real-time constraints of transactions are involved in controlling concurrent accesses to shared data. A detailed performance model of a distributed RTDBS was employed in the evaluation of concurrency control protocols.
Nutritive Value of Full-Fat Sunflower Seeds in Broiler Diets (2004)

A study was conducted to evaluate the nutritive value and inclusion level of sunflower seed (SFS) in broiler diets. SFS contained 38.7% ether extract (EE), 16.9% CP, 14.9% crude fiber (CF), 3.5% ash, 0.57% lysine, and 0.46% methionine (89.2% DM basis). The AME (kcal/ kg) content of SFS in roosters was 5,225 and in broilers at 4, 18, and 35 d of age was 3,493, 5,132, and 5,162, respectively. The CP, EE, and CF digestibilities were 80.4, 71.2, and 11.4%, respectively. In an isocaloric and isonitrogenous diet containing SFS at 0, 5, 10, 15, and 20%, SFS up to 20% did not affect weight gain and feed consumption, but the feed conversion ratio was improved (P < 0.05) when broilers were fed 15 or 20% SFS in the starter and finisher diets. CF digestibility of starter diet was significantly lower when 15 or 20% SFS was included. CF digestibility of the finisher diet and digestibility of other nutrients in starter and finisher diets were comparable in all treatment groups. Liver and muscle lipid content, plasma total and high-density lipoprotein cholesterol content, muscle cholesterol content, dressing percentage, liver weight, and giblet weight (as % live weight) were comparable among all treatment groups. Abdominal fat was increased in birds fed 20% SFS. Percentage skin was decreased in broilers fed > or = 10% SFS.
An automated student attendance tracking system based on voiceprint and location (2016)

Taking attendance has been widely used as a method to track students' academic behaviours. But conventional approaches are usually time consuming and inaccurate. In this paper, we have proposed an automated attendance tracking system, where students can use smartphones to submit attendance in parallel. Identity of a student is collaboratively verified by voiceprint and realtime location. Service isolation and token-based mechanism is applied specifically in the system as well, for the purpose of protecting users' privacy and the system's security. Tests in real world environment has demonstrated that our system is characterised as high efficiency and accuracy in tracking attendance.
High-temporal contrast using low-gain optical parametric amplification (2009)

We demonstrate the use of low-gain optical parametric amplification (OPA) as a means of improving temporal contrast to a detection-limited level 10(-10). 250 microJ, 500 fs pulses of 1053 nm are frequency doubled and subsequently restored to the original wavelength by OPA with >10% efficiency.

Energy Levels and Observed Spectral Lines of Krypton, Kr I through Kr XXXVI (2007)

The energy levels and observed spectral lines of the krypton atom, in all stages of ionization for which experimental data are available, have been compiled. Sufficient data were found to generate level and line tables for Kr I–Kr X and Kr XVIII–Kr XXXVI. For Kr XXXV and Kr XXXVI and most of Kr XXXIV theoretical values are compiled for the energy levels. In all of the other stages a few lines, some of which may be only tentative classifications, are reported. In addition for Kr I, separate tables of energy levels are tabulated for the isotopes Kr86 and Kr84. Experimental g factors are included for Kr I and Kr II. A value, either experimental, semiempirical, or theoretical, is included for the ionization energy of each ion.
Elliptically-bent crystal spectrograph for X-ray diagnosis of laser-produced plasmas (2004)

In order to measure spatially and temporarily resolved laser-produced plasma X-ray spectra in 0.2-2 nm region, a novel two-channel elliptically-bent crystal spectrograph has been developed. Dispersive elements are LiF, PET, Mica, and KAP crystals, which cover Bragg angles in the range of 30-67.5 degrees. Eccentricity and focal distance of twin ellipses are 0.9586 and 1350 mm, respectively. Spatially resolved spectrum is photographically recorded with an X-ray film or X-CCD camera in one channel, and temporarily resolved one is photographically recorded with an X-ray streak camera in another channel, thus spatially and temporarily resolved spectra can be simultaneously obtained. Spectral images were acquired with X-CCD and PET in SHENGUANG-II laser facility, and experimental results show that the spectral resolution of the spectrograph is about 0.002 nm.

The attractiveness of flowering herbaceous plants to bees (Hymenoptera: Apoidea) and hoverflies (Diptera: Syrphidae) in agro‐ecosystems of Central Spain (2014)

Abstract Habitat management, with the aim of conserving pollinators in agro‐ecosystems, requires the selection of the most suitable floral species in terms of their attractiveness to pollinators and a simplicity of agronomic management. A randomized block design including 12 herbaceous plants was used to study their attractiveness to pollinators (insect visitation), their attractiveness efficiency (a combination of duration of flowering and insect visitation), their response to two different agronomic management practices (growing in mixed versus mono‐specific stands; tillage versus no‐tillage) and their potential weediness. The flowers of Borago officinalis , Echium plantagineum , Phacelia tanacetifolia and Diplotaxis tenuifolia were attractive to bees, whereas Calendula arvensis , Coriandrum sativum , D. tenuifolia and Lobularia maritima were attractive to hoverflies. A floral mixture resulted in a lower attractiveness efficiency to pollinators than D. tenuifolia , but higher than when compared with most of the mono‐specific stands. On the other hand, although some of the most attractive plant species ( P. tanacetifolia and C. arvensis) showed potential weediness, their self‐seeding was reduced by tillage treatment. Diplotaxis tenuifolia was the only plant with a high attractiveness efficiency to pollinators and efficient self‐reproduction. Therefore, D. tenuifolia is highly recommended species for attracting bees and hoverflies in agro‐ecosystems of Central Spain.
An Abstract Syntax Tree Encoding Method for Cross-Project Defect Prediction (2019)

In the last few years, with the development of deep learning theory, researchers have tried to introduce the method of artificial intelligence into the field of software defect prediction (SDP) to improve its prediction effect. To be fed into the neural network, the sample codes are represented as an abstract syntax tree (AST), and the AST is encoded as real numbers. However, in most cross-project defect prediction (CPDP) task, the method for converting the AST into a real number cannot effectively estimate the semantic distance between the ASTs, resulting in a significant reduction in training effects. To solve that problem, we present a new encoding framework, tree-based-embedding (TBE), to convert AST into real vectors and make the semantic gap between the ASTs measurable. To estimate the effect of this encoding method, we promise a tree-based-embedding convolutional neural network with transferable hybrid feature learning (TBCNN-THFL) to perform the CPDP tasks. TBCNN-THFL is fed data encoded with TBE method for learning the transferable joint features between different projects; meanwhile, TBCNN-THFL introduces a transfer component analysis algorithm. Furthermore, the model combines the handcrafted and deep-learning-generated features and then feeds them into the classifier to train a defect prediction model. A sufficient number of experiments demonstrate that TBCNN-THFL is superior to referential models on 72 pairs of CPDP tasks formed by 9 open-source projects.
Protection evaluation against <i>Chlamydophila abortus</i> challenge by DNA vaccination with a <i>dnaK</i>-encoding plasmid in pregnant and non-pregnant mice (2002)

Mice were intramuscularly immunized with a dnaK-encoding DNA plasmid. The protective effect of DNA immunization against Chlamydophila abortus infection was studied in pregnant and non-pregnant mice models. In non-pregnant mice, the dnaK vaccine induced a specific humoral response with the predominant IgG2a isotype, which failed to have in vitro neutralizing properties. No delayed-type hypersensitivity reaction was observed and the spleens of dnaK vaccinated-mice were not protected against C. abortus challenge. In pregnant mice, the dnaK vaccine induced a non-specific partial protection from abortion. This may be due to the immunogenic properties of the CpG motifs of bacterial DNA present in the vaccinal plasmid backbone. Nevertheless, spleens of dnaK vaccinated-pregnant mice were not protected.
Molecular Dissection of DNA Sequences and Factors Involved in Slow Muscle-Specific Transcription (2001)

Transcription is a major regulatory mechanism for the generation of slow- and fast-twitch myofibers. We previously identified an upstream region of the slow TnI gene (slow upstream regulatory element [SURE]) and an intronic region of the fast TnI gene (fast intronic regulatory element [FIRE]) that are sufficient to direct fiber type-specific transcription in transgenic mice. Here we demonstrate that the downstream half of TnI SURE, containing E box, NFAT, MEF-2, and CACC motifs, is sufficient to confer pan-skeletal muscle-specific expression in transgenic mice. However, upstream regions of SURE and FIRE are required for slow and fast fiber type specificity, respectively. By adding back upstream SURE sequences to the pan-muscle-specific enhancer, we delineated a 15-bp region necessary for slow muscle specificity. Using this sequence in a yeast one-hybrid screen, we isolated cDNAs for general transcription factor 3 (GTF3)/muscle TFII-I repeat domain-containing protein 1 (MusTRD1). GTF3 is a multidomain nuclear protein related to initiator element-binding transcription factor TF II-I; the genes for both proteins are deleted in persons with Williams-Beuren syndrome, who often manifest muscle weakness. Gel retardation assays revealed that full-length GTF3, as well as its carboxy-terminal half, specifically bind the bicoid-like motif of SURE (GTTAATCCG). GTF3 expression is neither muscle nor fiber type specific. Its levels are highest during a period of fetal development that coincides with the emergence of specific fiber types and transiently increases in regenerating muscles damaged by bupivacaine. We further show that transcription from TnI SURE is repressed by GTF3 when overexpressed in electroporated adult soleus muscles. These results suggest a role for GTF3 as a regulator of slow TnI expression during early stages of muscle development and suggest how it could contribute to Williams-Beuren syndrome.
