Relationships between bacteria, phytoplankton and particulate organic carbon in the upper St. Lawrence Estuary

The relationships between bacterial and phytoplankton variables, and particulate organlc carbon (POC), were examined along a longitudinal transect in the St. Lawrence Estuary Free bacteria, bacterial biomass and heterotrophic activity decreased in a seaward direction, whereas chlorophyll, phytoplankton biomass and photosynthetic act~vity had minimum values in the mid-estuanne region Values of POC and attached bacteria were h~ghes t at the upper limit of the salinity intrusion, in the zone of ~naximum turbidity. Free bacteria predominated largely over attached bacteria, which were probably of benthic origin. It is hypothesized that free and attached bacteria formed 2 distinct, independent communities Correlation analysis showed that, in general, bacterial and phytoplankton vanables were highly correlated and that these variables were linked to salinity The effect of salin~ty on these correlations was controlled u s ~ n g partial correlat~on analys~s and the results showed that only attached bactena of the maxlmum turb~dity zone were signif~cantly col-related w ~ t h chlorophyll and POC concentrations. Elsewhere, phytoplankton and bacterial variables were not correlated. Careful estlmation revealed that bacterial b~omass largely exceeded that of phytoplankton everywhere, except at the most seaward station, where coastal rather than ~ s t u a r ~ n e condit~ons prevailed This study thus suggests that phytoplankton and POC did not to a large extent de t e rm~ne bacterial distribut~on in the Upper St. Lawrence Estuary and that bacteria may have a relatively important trophic role In t h ~ s ystem
Expression of Tn and sialyl Tn antigens in synovial tissues in rheumatoid arthritis.

OBJECTIVES The carbohydrate chains represented by mucins (MUCs) are expressed by a variety of normal and malignant secretory epithelial cells and induce a variety of immunoreactions. Tn and sialyl Tn antigens are tumour-associated carbohydrate antigens which are borne on the core proteins of mucins. The purpose of this study is to investigate the existence of tumour-associated carbohydrate antigens in rheumatoid arthritis (RA). METHODS . We examined the expression of Tn and sialyl Tn antigens in synovial tissues from RA and osteoarthritis (OA) patients by immunohistochemistry. In addition, mucins from synovial fluid (SF) from RA patients are purified by gel filtration and density gradient ultracentrifugation and the existence of these antigens examined by dot and Western blotting. RESULTS We found that Tn and sialyl Tn antigens were strongly expressed in synovial cells and infiltrating mononuclear cells on the sublining layer and lymphoid follicles in synovial tissues in RA compared with those in osteoarthritis. Tn and sialyl Tn antigens were detected in purified mucins of SF from RA patients. CONCLUSIONS Tumour-like synovial hyperplasia cells expressed Tn and sialyl Tn antigens. This finding suggests that the mucins exhibiting with abnormal glycosylation may be in part responsible for synovial hyperplasia, leading to the joint destruction in the pathogenesis of RA.
Multichannel wearable fNIRS‐EEG system for long‐term clinical monitoring

Continuous brain imaging techniques can be beneficial for the monitoring of neurological pathologies (such as epilepsy or stroke) and neuroimaging protocols involving movement. Among existing ones, functional near‐infrared spectroscopy (fNIRS) and electroencephalography (EEG) have the advantage of being noninvasive, nonobstructive, inexpensive, yield portable solutions, and offer complementary monitoring of electrical and local hemodynamic activities. This article presents a novel system with 128 fNIRS channels and 32 EEG channels with the potential to cover a larger fraction of the adult superficial cortex than earlier works, is integrated with 32 EEG channels, is light and battery‐powered to improve portability, and can transmit data wirelessly to an interface for real‐time display of electrical and hemodynamic activities. A novel fNIRS‐EEG stretchable cap, two analog channels for auxiliary data (e.g., electrocardiogram), eight digital triggers for event‐related protocols and an internal accelerometer for movement artifacts removal contribute to improve data acquisition quality. The system can run continuously for 24 h. Following instrumentation validation and reliability on a solid phantom, performance was evaluated on (1) 12 healthy participants during either a visual (checkerboard) task at rest or while pedalling on a stationary bicycle or a cognitive (language) task and (2) 4 patients admitted either to the epilepsy (n = 3) or stroke (n = 1) units. Data analysis confirmed expected hemodynamic variations during validation recordings and useful clinical information during in‐hospital testing. To the best of our knowledge, this is the first demonstration of a wearable wireless multichannel fNIRS‐EEG monitoring system in patients with neurological conditions.

Finger-fist detection in first-person view based on monocular vision using Haar-like features

This paper introduces a new idea for interaction between human and wearable device which is using finger-fist posture to be the detecting and tracking target. We built the detector with cascade classier using Haar-like features and the AdaBoost learning algorithm. The detector for the posture shows good tolerance for out-of-plane rotation and robustness against lighting variance and cluster background. With excellent real-time performance and high recognition accuracy, the detection can be acted as a tracker to track the path of fist in the first-person view.
Determinants of Capital Structure in the Indian Pharma Sector

This study analyses the determinants of capital structure in the Indian pharma sector using pooled regression and panel regression modeling. The results of the study suggest that financial leverage in Indian pharma companies is determined primarily by two factors: it is positively related with Non-Debt Tax Shield and negatively related with Profitability. Paradoxically, the former finding supports the Static Trade-Off theory, as companies would prefer debt financing due to its tax benefits, while the latter finding supports the Pecking Order theory, as more profitable companies would prefer internal sources of funds. This could mean that pharma companies would prefer to finance their initial capital expenditure through debt due to its tax advantage, but as they become more profitable they prefer to turn to internal sources. This switch-over behaviour, whereby companies would be expected to switch from financing through debt to retained earnings, should be investigated in further detail, in the pharma sector and in other capital-intensive industries.
Leveraging Battery Usage from Mobile Devices for Active Authentication

Active authentication is the practice of continuously verifying the identity of users, based on their context, interactions with a system, and information provided by that system. In this paper, we investigate if battery charge readings from mobile devices can be used as an extra factor to improve active authentication. We make use of a large data set of battery charge readings from real users and construct two computationally inexpensive machine learning classifiers to predict if a user session is authentic: the first one only based on the battery charge at a certain time of day; the second one predicts the authenticity of the user session when a previous, recent battery charge reading is available. Our research shows that a simple two-figure battery charge value can make a useful albeit minor contribution to active authentication.
Comparing the fixed combination brimonidine-timolol versus fixed combination dorzolamide-timolol in patients with elevated intraocular pressure*

ABSTRACT Purpose: To evaluate the efficacy of fixed combination brimonidine-timolol (FCBT) versus fixed combination dorzolamide-timolol (FCDT) given twice daily in patients with primary open angle glaucoma (POAG) or ocular hypertension (OH). Design: Prospective, multicentre, masked-observer, crossover comparison. Participants: Sixteen patients with POAG and 14 with OH. Methods: The participants of the study were washed out from their previous medication and randomized to fixed FCBT or FCDT for the first 4‑week treatment period. Subjects then were washed for 4 weeks and started on the opposite medication forthe second 4‑week period. Intraocular pressure (IOP) was measured with a Goldmann applanation tonometer at 8:00 a.m., 12:00 noon and 4:00 p.m. at each baseline and at the end of each treatment period. Unsolicited ocular adverse events were also recorded. Main outcome measures: Comparison of the IOP lowering effect of FCBT and FCDT. Results: The baseline mean diurnal IOP for all 30 subjects (30 eyes) was 22.9 ± 1.6 mmHg. Both fixed combinations significantly reduced IOP compared with baseline ( p < 0.00001). The mean diurnal IOP following 4 weeks of therapy was 15.0 ± 2.1 mmHg for FCBT and 15.4 ± 2.1 mmHg for FCDT ( p = 0.510). The mean diurnal IOP reduction was 7.8 ± 1.9 mmHg for FCBT and 7.4 ± 1.8 mmHg for FCDT ( p = 0.430). Overall, 14 subjects complained about ocular adverse events: two only for FCBT, seven only for FCDT and five for both drugs. Although there was no significant difference between the number of subjects that reported ocular adverse events with FCBT (n = 7) and FCDT (n = 12) ( p = 0.359), FCDT caused more ocular stinging upon instillation (n = 9) than FCBT (n = 1) ( p = 0.027). Conclusion: This study suggests that FCBT and FCDT, each given twice daily, have similar efficacy in patients with POAG or OH.
Effects of Nishyinda, black pepper and cinnamon extract as growth promoter in broilers

An extract of nishyinda ( Vitex negundo ) leaves, black pepper ( Piper nigrum ) and cinnamon ( Cinnamomum verum ) (polyherbal extract) were used as growth promoter in broilers. A total of 20 day-old broiler chicks were purchased and after seven days of acclimatization randomly divided into two equal groups. No vaccination schedule was practised and no antibiotics were added in rations. Group A served as control while group B was supplemented with polyherbal extract 1 mL/litre in drinking water. Weekly body weight gain up to six weeks was measured and blood tests were performed at 21 and 42 days. Polyherbal extract significantly (P<0.05) improved weight gain. There was no change in haematological parameters. It can be concluded that the polyherbal extract was safe as a growth promoter in broiler production without adverse effects on chicken health.

Some Determinants of Success or Failure of Emerging SACCOS in Tanzania

: This paper identifies and analyses factors associated with the success or failure of the emerging Savings and Credit Cooperative Societies (SACCOS) in Tanzania Mainland. Multi-stage sampling technique was employed to come up with four regions among ten purposively selected for the study. Four research questions were formulated to guide the study. 156 respondents participated in the study and data were analyzed using IBM SPSS Statistics version 20.0 software. Principal component analysis and logistic regression analysis were used in the analysis. The study revealed that,lack of access to loans for individuals, a need of soft loans for business and non business; and pledges for loans from government, prominent politicians and other stakeholders were the main factors that led to the SACCOS inception. It was shown that accepting ‘non members businesses, having and adhering to conflict management strategy, number of members at initial stage and employing fulltime professional management made a significant contribution to success performance of SACCOS. Moreover, SACCOS shown poor performance as compared to SACCOS operating in urban areas while education level has shown a positive relationship with SACCOS’ performance. The findings also showed that lack of commitment to members, lack of patience, shifting to other areas and loan default the major for members’ withdrawal from study recommended encouraging female members for SACCOS’ leadership since they have shown success performance in most of the SACCOS they lead. this study finding giving priority to female members in
MMPI-A Validity Scale Uses and Limitations in Detecting Varying Levels of Random Responding

Although there is a substantial research literature on the effects of random responding on the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989), there are very few studies available on this topic with the MMPI-A (Butcher et al., 1992). Archer and Elkins (1999) found that MMPI-A validity scales F and VRIN were particularly useful in detecting entirely random profiles from those derived standardly in clinical settings but noted that "all random" protocols could not be used to evaluate the usefulness of the T-score difference between the first half (F1) and the second half (F2) of the MMPI-A test booklet. Following up on this issue, this study extended the methodology of previous research by examining the hit rate, positive predictive power, negative predictive power, sensitivity, and specificity of VRIN, F, F1, F2 and the absolute value of the T-score difference between F1 and F2 (denoted as |F1 - F2|) in 5 samples varying in the degree of protocol randomness. One of the samples consisted of 100 adolescent inpatients administered the MMPI-A under standard instructions, and another sample consisted of 100 protocols randomly generated by computer. The additional 3 samples of 100 protocols each contained varying degrees of computer-generated randomness introduced in the latter half of the MMPI-A item pool. Overall, the results generally indicate that several MMPI-A validity scales are useful in detecting protocols that are largely random, but all of these validity scales are more limited in detecting partially random responding that involves less than half the total item pool located in the second half of the test booklet. Clinicians should be particularly cautious concerning validity inferences based on the observed T-score difference that occurs for the F1 and F2 subscales and current findings do not support the clinical usefulness of this index.
Recent approaches on authorship attribution techniques — An overview

Authorship analysis deals with the identification of authors which is a problem of text data mining and classification. There are numerous techniques and algorithms that have been published so far, in the field of stylometry. In this regard, the primary objective of the present review is to provide the status of the different studies carried out on authorship analysis based on the important research contributions. The authors have mainly focused on each of the article selected for review (2010–16), by summarizing the authorship detection fields, the corpus, the features of authorship analysis, and authorship attribution techniques used which could provide a platform to distinguish between different research contributions and the diverse techniques used in classifying the author's texts. The details on common tools and authorship attribution techniques published in the recent past would be of importance to the concerned researchers as an aid towards text data mining and future growth in the study of authorship attribution.
Counterflow centrifugation of red cell populations: a cell age related separation technique

Summary. Red cell populations were fractionated on the basis of differences in density by a centrifugation method described by Murphy and on the basis of differences in mean cell volume (MCV) by counterflow centrifugation. By 59Fe‐incorporation and determination of the HbA1c content, both methods were studied for their ability to separate red cell populations into fractions of different mean cell age. It can be concluded that separation on the basis of differences in cell volume results in a linear separation according to age whereas separation on the basis of density only results in an accumulation of very young cells in the top fractions. A gradual decrease in cell volume with age, combined with a constant haemoglobin concentration in the cells, indicates release of haemoglobin from the red cells during their lifespan.
A putative transmembrane protein with histidine-rich charge clusters encoded in the H-2K/tw5 region of mice

The H-2 complex of mice contains many genes in addition to the gene families involved in immune reactions. Some of them are believed to function in mouse development, as suggested by the findings that several embryonic lethal mutations map within or near the H-2 complex. We have analyzed the H-2K/tw5 region in an attempt to study non-H-2 genes encoded in this region. Overlapping cosmid clones spanning about 170 kilobase pairs of DNA, including the H-2K/tw5 region of the mouse, have been screened for genes expressed in embryonic carcinoma cells. A transcript of 2.8 kilobase pairs (K. Abe. J.-F. Wei, F.-S. Wei, Y.-C. Hsu, H. Uehara, K. Artzt, and D. Bennett, EMBO J. 7:3441-3449, 1988) encoded by the KE 4 gene flanking H-2K distally was identified. The transcript was abundantly expressed in embryonic carcinoma cells but was present at low levels in other tissues in adults. A cDNA for this transcript was isolated from the F9 embryonic carcinoma cell line and sequenced. It potentially encodes a protein of 436 amino acids with several interesting features. First, it contains two regions made of well-conserved repeats unusually rich in histidine residues. In the repeats, histidine alternates with other amino acids, notably glycine or serine. Second, the two histidine-rich regions are separated by three putative membrane-spanning domains. Third, the N-terminal part of the sequence shows characteristics of a signal peptide. The results indicate that the protein coded by the gene may be a transmembrane protein with histidine-rich charge clusters. A similar sequence motif found in other known genes allows speculation on the possible functional of this gene.
Three-body Coulomb problem probed by mapping the Bethe surface in ionizing ion-atom collisions.

The three-body Coulomb problem has been explored in kinematically complete experiments on single ionization of helium by 100 MeV/u C(6+) and 3.6 MeV/u Au(53+) impact. Low-energy electron emission ( E(e)<150 eV) as a function of the projectile deflection theta(p) (momentum transfer), i.e., the Bethe surface [15], has been mapped with Delta theta(p)+/-25 nanoradian resolution at extremely large perturbations ( 3.6 MeV/u Au(53+)) where single ionization occurs at impact parameters of typically 10 times the He K-shell radius. The experimental data are not in agreement with state-of-the-art continuum distorted wave-eikonal initial state theory.
Comparison of the Vidas C. difficile GDH Automated Enzyme-Linked Fluorescence Immunoassay (ELFA) with Another Commercial Enzyme Immunoassay (EIA) (Quik Chek-60), Two Selective Media, and a PCR Assay for gluD for Detection of Clostridium difficile in Fecal Samples

ABSTRACT Prevention and management of Clostridium difficile infection (CDI) can be improved by rapid and reliable diagnostics. The Vidas C. difficile glutamate dehydrogenase assay had performance comparable to that of the Quik Chek-60 assay (overall agreement, 95%) and a sensitivity of >93%; thus, it is suitable as the first test in two-stage algorithms for a CDI diagnosis.

Process variation-tolerant 3D microprocessor design: An efficient architectural solution

Process variation is one of the most challenging problems for 3D microprocessors. This is because stacked dies are likely to have fairly different characteristics due to wafer-to-wafer (W2W) variations, which may severely hurt yield of 3D microprocessors. In this paper, we introduce a process variation-tolerant 3D microprocessor design that exploits an architectural insight: narrow-width values. The main target of our technique is last-level caches (LLCs), which are composed of several dies. By storing only the meaningful bit parts within a data word into the LLCs while discarding the zero bit parts (which can be recovered by the zero-extension logic), our proposed technique improves a storage efficiency of the LLCs, which eventually enhances cache yield. According to our evaluation results, our technique significantly improves cache yield in a performance-/energy-efficient manner.
A new power supply system for AC contactor ride-through

This paper describes a new power supply system that enables an AC contactor to ride through power grid disturbances. The proposed system is implemented in an electronic device that is connected to the contactor coil. The electronic device consists of a power conversion and excitation circuit, a control circuit, an immunity circuit and a shutdown circuit. It does not disturb the contactor operation and can be adapted to almost all types of electrical contactor. Experimental tests have demonstrated the effectiveness of the proposed electronic device.
Nanoparticle self-assembly based tripetaloid arrayed structures as surface-enhanced raman scattering substrates

This paper reports a novel highly-ordered tripetaloid arrayed structure (TPAS) which performs very well as an active surface-enhanced Raman scattering (SERS) substrate for its notable reproducibility and enormous SERS enhancement factor (EF). The TPAS is easily fabricated by anisotropic etching of a self-assembly silica-nanoparticle bilayer and a following metal deposition. Electromagnetic simulation indicates that the edge protrusions and narrow gaps of the structure act as hot spots. SERS experiments show that the EF of Au-film-covered TPAS is 12 times higher than that of regular Au-film-over-nanoparticles (AuFON). The spatially average EF of the TPAS is as high as 5.7×106, and the local EF of its hot spots is much higher.

Novel FIR approximations of IIR differentiators with applications to image edge detection

In this work, an FIR approximation of the Al-Alaoui first order IIR differentiator is presented. The resulting FIR filter is shown to perform a good approximation of the IIR differentiator. Furthermore, it is shown to outperform other FIR approximations, obtained via windowing techniques, of the Al-Alaoui first order IIR differentiator. The obtained FIR differentiator is used to generate masks for image edge detection. The results show the superiority of the masks derived from the new FIR filter when compared to other techniques in image edge detection.
