Android vs Windows Mobile vs Java ME (2010)

In this paper we look at three mobile development environments: Windows Mobile, Java ME and Android. Through platform comparison, the different environments are examined closely and strengths and weaknesses are brought to life. In all three environments example applications are written to compare the environments in action on respective devices. Environment specific deployment files are created to illustrate amount of boilerplate code and overhead during deployment. Different key areas such as implementation aspects, performance aspects and quality assurance are compared to give an in depth overview of the status of the different platforms. Our results show that although the three environments are similar in some aspects they still represent three distinctive fields each with their respective characteristics. Through our code examples and platform comparison we come to the conclusion that the Windows Mobile and Android platform provides a better development environment, whereas Java ME still struggles with poor emulator support and incompatible implementations. The main features they have in common are also seen in trends directly visible in the programming languages such as unit testing, language features and end user distribution strategies. Big differences are highlighted when inspecting community environments, hardware abilities and platform maturity. This will have large influence on the choice of development platform for creating novel assistive environment applications.
Well Performance Analysis and Deliverability Monitoring for Layered Reservoirs Without Crossflow (1995)

ABSTRACT This paper presents a case history study that demonstrates monitoring bottom-hole well deliverability performance for flowing oil-wells completed in layered reservoirs. The field of study is the recently developed Xijiang 24-3 Field, offshore China in the Pearl River Mouth Basin. Development of the bottom-hole backpressure curve for individual layer packages and total well are presented as a reservoir management tool. A combination of individual layer production well tests, production logging tool (PLT) measurements and permanent downhole bottom-hole pressure readings are utilized to develop the total well bottom-hole backpressure curve. Pre-gravel pack and post-gravel pack results are discussed and compared to daily production measurements. The bottom-hole backpressure curve is shown to be an effective reservoir management tool to monitor well and reservoir performance.
Immunodetection of human T-cell lymphotropic virus type I core protein in biological samples by using a monoclonal antibody immunoassay (1990)

A monoclonal antibody-based enzyme immunoassay (EIA) has been developed for detection of human T-cell lymphotropic virus type I (HTLV-I) core protein. The monoclonal antibody (clone 6.11) specifically recognizes the p19 gag gene-encoded protein of the virus. The EIA was over 100 times more sensitive than reverse transcriptase measurement and was capable of responding to less than 500 pg of whole-virus lysate. The assay exhibited type specificity in that HTLV-II antigens failed to produce a positive signal. In addition, a panel of other viruses demonstrated no antigenic cross-reactivity. These included herpesviruses, measles virus, human immunodeficiency viruses, and others. Viral p19 was followed during the course of density gradient ultracentrifugation in the presence of detergent, where it was noted to associate with viral membrane proteins. In comparison, reverse transcriptase activity localized in fractions of higher density containing envelope-free cores. Of clinical interest, the EIA was used to detect HTLV-I antigen in the viral cultures of patients with HTLV-I-associated myelopathies and from symptom-free individuals with proviral integration.
Effects of the neutrophil-activating peptide NAP-2, platelet basic protein, connective tissue-activating peptide III and platelet factor 4 on human neutrophils. (1989)

Platelet basic protein (PBP), connective tissue-activating peptide III (CTAP-III), and platelet factor 4 (PF-4) were purified from human platelet release supernatants by heparin-Sepharose ion-exchange and reversed-phase HPLC, and their neutrophil-activating effects were compared with those of NAP-2, a peptide of 70 amino acids corresponding to part of the sequence of PBP (1) and with sequence homology to NAF/NAP-1. NAP-2-induced elastase release and a rise in cytosolic free Ca2+ at concentrations between 0.3 and 100 nM, and neutrophil chemotaxis at concentrations between 0.03 and 10 nM. It was half as potent as NAF/NAP-1 in inducing exocytosis but showed the same activity in the other responses. By contrast, only minimal if any effects were obtained with PBP, CTAP-III, and PF-4 up to 100 nM. NAP-2 thus appears to behave like a typical chemotactic receptor agonist. It could be generated from PBP and/or CTAP-III released from activated platelets and lead to the accumulation of neutrophils in platelet aggregates.
Mutations in the P1 promoter region of Micromonospora echinospora (1992)

We demonstrated previously that the promoters P1a, P1b, and P1c are very closely spaced and are coordinately turned on during stationary phase in Micromonospora echinospora. To determine the nucleotides important for promoter recognition, we characterized mutations that were defective in transcription from the P1b start site, using Streptomyces lividans as the host. Two mutations upstream of the start site resulted in a drastic loss of promoter activity, while two mutations downstream of the start site resulted in a moderate loss of activity. These mutations suggest an unexpected relationship between promoters P1b and P1c. Three of the mutations that caused diminished transcription from promoter P1b simultaneously resulted in an increase in transcription from the P1c promoter initiation site located 15 bp downstream. Despite the proximity and the coordinate regulation of promoters P1b and P1c, they are in competition as transcriptional start sites.
Recognition of Age-damaged (R,S)-Adenosyl-L-methionine by Two Methyltransferases in the Yeast Saccharomyces cerevisiae (2007)

The biological methyl donor S-adenosylmethionine (AdoMet) can exist in two diastereoisomeric states with respect to its sulfonium ion. The S configuration, (S,S)-AdoMet, is the only form that is produced enzymatically as well as the only form used in almost all biological methylation reactions. Under physiological conditions, however, the sulfonium ion can spontaneously racemize to the R form, producing (R,S)-AdoMet. As of yet, (R,S)-AdoMet has no known physiological function and may inhibit cellular reactions. In this study, we found two Saccharomyces cerevisiae enzymes that are capable of recognizing (R,S)-AdoMet and using it to methylate homocysteine to form methionine. These enzymes are the products of the SAM4 and MHT1 genes, identified previously as homocysteine methyltransferases dependent upon AdoMet and S-methylmethionine, respectively. We found here that Sam4 recognizes both (S,S)- and (R,S)-AdoMet, but that its activity is much higher with the R,S form. Mht1 reacts with only the R,S form of AdoMet, whereas no activity is seen with the S,S form. R,S-Specific homocysteine methyltransferase activity is also shown here to occur in extracts of Arabidopsis thaliana, Drosophila melanogaster, and Caenorhabditis elegans, but has not been detected in several tissue extracts of Mus musculus. Such activity may function to prevent the accumulation of (R,S)-AdoMet in these organisms.

Graphene-Side-Gate Engineering (2012)

Various mesoscopic devices exploit electrostatic side gates for their operation. In this letter, we investigate how voltage biasing of graphene side gates modulates the electrical transport characteristics of a graphene channel. We explore myriads of typical side-gated devices such as symmetric dual-side gates and asymmetric single-side gates, in monolayer and bilayer graphene. The side gates modulate the electrostatic doping in the graphene channel whose effect is reflected in transport measurement. This modulation efficiency is systematically characterized for all our devices and agrees well with the modeling presented.
Interference with clinical laboratory analyses (1994)

Interference by endogenous and exogenous substances with assays for clinical analytes is a common problem in laboratory medicine. For this review, we defined interference as "the effect of a substance present in the sample that alters the correct value of the result, usually expressed as concentration or activity, for an analyte." There are four major endogenous compounds that consistently interfere with laboratory results: hemoglobin, bilirubin, lipids, and paraproteins. The major exogenous sources of interference are drugs prescribed for the patient; and there are several excellent compendia of the effect of drugs on clinical laboratory tests. We recommend determining whether the interference is dependent or independent of the analyte for the assay. Further, we propose an approach to the identification and resolution of an interference problem for the clinical laboratory and make recommendations to manufacturers.
Phosphorylation of threonine 3 on histone H3 by Haspin kinase is required for meiosis I in mouse oocytes (2014)

Meiosis I (MI), the division that generates haploids, is prone to errors that lead to aneuploidy in females. Haspin is a kinase that phosphorylates histone H3 on threonine 3, thereby recruiting Aurora kinase B (AURKB) and the chromosomal passenger complex (CPC) to kinetochores to regulate mitosis. Haspin and AURKC, an AURKB homolog, are enriched in germ cells, yet their significance in regulating MI is not fully understood. Using inhibitors and overexpression approaches, we show a role for haspin during MI in mouse oocytes. Haspin-perturbed oocytes display abnormalities in chromosome morphology and alignment, improper kinetochore-microtubule attachments at metaphase I and aneuploidy at metaphase II. Unlike in mitosis, kinetochore localization remained intact, whereas the distribution of the CPC along chromosomes was absent. The meiotic defects following haspin inhibition were similar to those observed in oocytes where AURKC was inhibited, suggesting that the correction of microtubule attachments during MI requires AURKC along chromosome arms rather than at kinetochores. Our data implicate haspin as a regulator of the CPC and chromosome segregation during MI, while highlighting important differences in how chromosome segregation is regulated between MI and mitosis.
Polypeptide Synthesis in Simian Virus 5-Infected Cells (1977)

Polypeptide synthesis in three different cell types infected with simian virus 5 has been examined using high-resolution polyacrylamide slab gel electrophoresis, and all of the known viral polypeptides have been identified above the host cell background. The polypeptides were synthesized in infected cells in unequal proportions, which are approximately the same as they are found in virions, suggesting that their relative rates of synthesis are controlled. The nucleocapsid polypeptide (NP) was the first to be detected in infected cells, and by 12 to 14 h the other virion structural polypeptides were identified, except for the polypeptides comprising the smaller glycoprotein (F). However, a glycosylated precursor (F(0)) with a molecular weight of 66,000 was found in each cell type, and pulse-chase experiments suggested that this precursor was cleaved to yield polypeptides F(1) and F(2). No other proteolytic processing was found. In addition to the structural polypeptides, the synthesis of five other polypeptides, designated I through V, has been observed in simian virus 5-infected cells. One of these (V), with a molecular weight of 24,000, was found in all cells examined and may be a nonstructural viral polypeptide. In contrast, there are polypeptides present in uninfected cells that correspond in size to polypeptides I through IV, and similar polypeptides have also been detected in increased amounts in cells infected with Sendai virus. These findings, and the fact that the synthesis of all four of these polypeptides is not increased in every cell type, suggest that they represent host polypeptides whose synthesis may be enhanced upon infection. When a high salt concentration was used to decrease host cell protein synthesis in infected cells, polypeptides IV and (to a lesser extent) I were synthesized in relatively greater amounts than other cellular polypeptides, as were the viral polypeptides. The possibility that these polypeptides may play some role in virus replication is discussed.

Electric Quadrupole Shift Cancellation in Single-Ion Optical Frequency Standards (2005)

The electric quadrupole shift is presently the most significant source of uncertainty on the systematic shifts for several single-ion optical frequency standards. We present a simple method for cancelling this shift based on measurements of the Zeeman spectrum of the clock transition. This method is easy to implement and yields very high cancellation levels. A fractional uncertainty of 5 x 10(-18) for the canceled quadrupole shift is estimated for a measurement of the absolute frequency of the 5s (2)S(1/2)-4d (2)D(5/2) clock transition of 88Sr+.
Semi-automatic procedure to extract Couinaud liver segments from multislice CT data (2003)

Liver resection and transplantation surgeries require careful planning and accurate knowledge of the vascular and gross anatomy of the liver. This study aims to create a semi-automatic method for segmenting the liver, along with its entire venous vessel tree from multi-detector computed tomograms. Using fast marching and region-growth techniques along with morphological operations, we have developed a software package which can isolate the liver and the hepatic venous network from a user-selected seed point. The user is then presented with volumetric analysis of the liver and a 3-Dimensional surface rendering. Software tools allow the user to then analyze the lobes of the liver based upon venous anatomy, as defined by Couinaud. The software package also has utilities for data management, key image specification, commenting, and reporting. Seven patients were scanned with contrast on the Mx8000 CT scanner (Philips Medical Systems), the data was analyzed using our method and compared with results found using a manual method. The results show that the semi-automated method utilizes less time than manual methods, with results that are consistent and similar. Also, display of the venous network along with the entire liver in three dimensions is a unique feature of this software.
Semi-Supervised Nonnegative Matrix Factorization (2009)

Nonnegative matrix factorization (NMF) is a popular method for low-rank approximation of nonnegative matrix, providing a useful tool for representation learning that is valuable for clustering and classification. When a portion of data are labeled, the performance of clustering or classification is improved if the information on class labels is incorporated into NMF. To this end, we present semi-supervised NMF (SSNMF), where we jointly incorporate the data matrix and the (partial) class label matrix into NMF. We develop multiplicative updates for SSNMF to minimize a sum of weighted residuals, each of which involves the nonnegative 2-factor decomposition of the data matrix or the label matrix, sharing a common factor matrix. Experiments on document datasets and EEG datasets in BCI competition confirm that our method improves clustering as well as classification performance, compared to the standard NMF, stressing that semi-supervised NMF yields semi-supervised feature extraction.

Induction of superovulation by inhibin vaccine in cyclic guinea-pigs (2000)

Abstract Experiments were conducted to determine whether neutralizing endogenous inhibin affects follicular development and ovulation rate in guinea-pigs. Eighteen female guinea-pigs bearing 4 week progesterone implants were divided into three groups. At 1 week after removal of the progesterone implants, the animals were given a s.c. injection of 1 ml placebo (saline in oil emulsion; control), or 25 or 50 micrograms inhibin vaccine three times at 4 week intervals. Blood samples were collected once a week throughout the experiment for measuring inhibin antibody titres. After the third injection of inhibin vaccine, blood samples and ovaries were collected on the morning of day 8 after the day of oestrus. Inhibin vaccine increased the ovulation rate in a dose-dependent manner (placebo: 4.2 +/- 0.4; 25 micrograms inhibin vaccine: 6.2 +/- 0.9; 50 micrograms inhibin vaccine: 9.8 +/- 0.9) without any effects on the duration of the oestrous cycle. The results also showed that active immunization against inhibin increased the number of atretic follicles of 300-399 microns in diameter on day 8 after ovulation. The present study is the first to show that the active immunization against inhibin may be a useful method for inducing multiple ovulation in guinea-pigs.
Variable precision representation for efficient VQ codebook storage (2003)

In vector quantization (VQ) with fast search techniques, the storage available limits the number of codevectors used in VQ. Variable precision representation (VPR) is a simple codebook compression scheme. VPR for each vector y stores the number e(y), the number of leading bits which are zero in all elements, and avoids storing those leading bits. When storing the difference of codevectors in a binary tree structured VQ codebook, VPR can save from 24% to 44% in storage. Storing the codevector difference removes the redundancy between similar codevectors. Also as the mean square error of the VQ encoder is lowered, on the average, the difference becomes smaller and yields to better compression. To process vectors in VPR format, the operator uses a bit-serial, element-parallel scheme to evaluate the inner product. The operator's throughput can be increased by replicating its core.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Localization of a gene for familial recurrent arthritis (2000)

A gene for familial recurrent arthritis was localized to 15q22-24, as a result of a genome-wide linkage scan in a large, multiply affected kindred. Identification of the altered gene will provide insights into the pathogenesis of autoimmune joint destruction that is reminiscent of JIA.
Plasma Antioxidants and Risk of Cortical and Nuclear Cataract (1993)

We evaluated nutritional risk factors for cataract in 660 subjects enrolled in the Baltimore Longitudinal Study on Aging. As a part of a regular cycle of visits, nuclear and cortical lens photographs were taken over a 2-year period. Measurements of plasma antioxidants (beta-carotene, ascorbic acid, and alpha-tocopherol) were obtained in this cohort as part of the study protocol up to 4 years before lens photographs were taken. We found that plasma beta-carotene and ascorbic acid levels were not associated with risk of nuclear or cortical lens opacities. Higher levels of plasma alpha-tocopherol, however, were associated with a reduced risk of nuclear opacity [odds ratio (OR) for highest quartile vs lowest quartile = 0.52, 95% confidence interval (CI) = 0.27-0.98; OR for middle two quartiles vs lowest quartile = 0.55, 95% CI = 0.30-0.98], after adjusting for age, sex, and history of diabetes. Middle levels of alpha-tocopherol were associated with a reduced risk of cortical opacity (OR = 0.57, 95% CI = 0.32-1.02), but no such association was observed for high levels of alpha-tocopherol. We constructed an index of overall antioxidant status, which indicated that higher levels of plasma antioxidants were not associated with risk of nuclear or cortical opacities.
Measurement of phosphate anion based on optical fiber evanescent wave sensor (2011)

A new approach has been proposed to measure the concentration of phosphate anion in liquid via optical fiber evanescent wave method. A standard single-mode optical fiber is used and its extramural cladding is corrupted by hydrofluoric acid. The optical fiber sensor was put into phosphomolybdate blue solution with different concentrations. The evanescent wave of the fiber would be absorbed partly by the solution. The phosphate ion concentration can be obtained by measuring the optical output intensity of the fiber. The experimental results show that there is a linear relationship between the optical absorbance of the solution and the concentration of phosphor in the concentration range of0.04-0.4 mg/L with the detection sensitivity of0.53 L/mg and the linear dependent coefficient of0.918. The optical fiber sensors we have investigated are compact and deserve the opportunities for realizing the miniaturization of test equipment.
