A Survey of mid and large bodied mammals in Núcleo Caraguatatuba, Serra do Mar State Park, Brazil.

We applied complementary survey techniques to obtain a baseline species list of mid and large bodied mammals in Nucleo Caraguatatuba, Serra do Mar State park, Brazil. Between May and September 2011 we surveyed the community of mid and large bodied mammals using diurnal line transect census (212.4 km), camera-traps (223.2 camera-trap days) and track-stations (478 track-station days). A total of 18 species were recorded from 14 families in eight orders. We recorded the presence of seven species considered threatened in the State of Sao Paulo, including Primates (Brachyteles arachnoides), Artiodactyla (Mazama cf. americana and Tayassu pecari), Carnivora (Leopardus pardalis, Leopardus tigrinus and Puma concolor) and Perissodactyla (Tapirus terrestris). Based on extrapolated (First order jackknife) species richness estimates we predict that there are between 19 and 32 species of mid and large bodied mammals in the Nucleo. Our revised Mammal Priority Index ranked Nucleo Caraguatatuba as being of medium overall importance for the conservation of mid and large bodied mammals in the Atlantic Forest. Combined with the number and diversity of species recorded, our results demonstrate that this Nucleo is an important area for mammal conservation.
DEVELOPMENT OF AN UNDERACTUATED FINGER MECHANISM FOR A HAND PROSTHESIS

This works shows the conceptual development of a finger mechanism for a prothestic hand. Three degrees of freedom of the finger are actuated by single DC motor, characterizing therefore an underactuated mechanical system. Mechanical torque developed by the motor is transmitted to the phalanges through tendons and is converted into flexion and extension torques by means of small pulleys. The tendon is fixed on the tip of the distal phalange and conducted up to the motor pulley by passing around each pulley. The chosen servo motor is able to provide movement of the finger phalanges at an acceptable speed, as well as a reasonable amount of prehension force.

OPTIMIZATION OF LOCAL PARALLEL INDEX (LPI) IN PARALLEL/DISTRIBUTED DATABASE SYSTEMS

The widespread growth of data has created many problems for businesses, such as delay requests; in this paper, we propose several methods of partitioning an index B*Tree in multi-processor machines in parallel/distributed database systems and collaboration between processors when executing multi-queries. When optimizing, indexing automatically comes to mind; we distinguish two types of indexing: B*Tree and Bitmap. Since the advent of multicore computers (multi processors) parallelism becomes an indispensable part of optimization. Our work will focus on partitioning each table on three parts following indexing key partitioning; each processor will host a partition of the index, and the first processor that will finish will immediately take another partition of the index pending according to the priority. The parallelism will reduce the CPU cost then reduces execution time; collaboration between processors will further reduce these costs.
The Atmospheric Imaging Radar: Simultaneous Volumetric Observations Using a Phased Array Weather Radar

AbstractMobile weather radars often utilize rapid-scan strategies when collecting observations of severe weather. Various techniques have been used to improve volume update times, including the use of agile and multibeam radars. Imaging radars, similar in some respects to phased arrays, steer the radar beam in software, thus requiring no physical motion. In contrast to phased arrays, imaging radars gather data for an entire volume simultaneously within the field of view (FOV) of the radar, which is defined by a broad transmit beam. As a result, imaging radars provide update rates significantly exceeding those of existing mobile radars, including phased arrays. The Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU) is engaged in the design, construction, and testing of a mobile imaging weather radar system called the atmospheric imaging radar (AIR). Initial tests performed with the AIR demonstrate the benefits and versatility of utilizing beamforming techniques to achieve high spatial.
Análisis de robustez ante variaciones de proceso en amplificadores CMOS integrados de bajo ruido

En este articulo se presenta el analisis estadistico del comportamiento de diferentes amplificadores de bajo ruido (LNA) ante las variaciones de proceso presentes en una tecnologia de fabricacion de circuitos integrados CMOS, asi como el impacto de las variaciones que ocurren en el LNA sobre el desempeno del receptor. Los LNA fueron disenados utilizando una tecnologia CMOS de 130 nm y 1.2 V de alimentacion, siguiendo las especificaciones requeridas para receptores ZigBee® (estandar IEEE 802.15.4), en la banda de 2.4 GHz. Fueron estudiados circuitos con transistores de distintos valores de largo del canal y de corriente de polarizacion. De las simulaciones de Monte Carlo realizadas se obtuvo que la utilizacion de transistores de canal mas largo y con mayor consumo de potencia disminuyen la dispersion de los parametros de RF de los LNA, lo que aumenta el numero de circuitos que cumplen con las especificaciones trazadas. Se observo que las variaciones de los parametros de los amplificadores afectan en mayor medida el ruido del receptor que la linealidad, asociado a la caida de la ganancia del LNA por debajo del limite establecido. Los resultados presentados confirman la necesidad agregar el analisis de variabilidad a las metodologias de diseno convencionales de este tipo de circuito, con el objetivo de balancear el consumo de potencia y el costo de produccion (asociado a la relacion entre el numero de circuitos utiles y el total fabricado).
Repeated eigenstructure assignment in the computation of friends of output-nulling subspaces

This paper is concerned with the parameterisation of basis matrices and the simultaneous computation of friends of the output nulling subspaces V ⋆, V ⋆ g and R ⋆ with the assignment of the corresponding inner and outer closed-loop free eigenstructure. Differently from the classical techniques presented in the literature so far on this topic, which are based on the standard pole assignment algorithms and are therefore applicable only in the non-defective case, the method presented in this paper can be applied in the case of closed-loop eigenvalues with arbitrary multiplicity.
Emigration of B cells from chicken bursa of Fabricius

The extent of emigration of cells from the bursa of Fabricius to the periphery was estimated. Per anum application of fluorescein isothiocyanate to label bursal cells in situ was used. Migrant cells can be visualized on frozen sections or cell suspensions of peripheral organs by their fluorescence. The data show that at 2–3 weeks after hatching about 5% of bursal cells leave the bursa per day. Since the bursal cells divide rapidly, this indicates that the vast majority (95%) of bursal cells die in situ. Cells that leave the bursa are surface IgM positive and go first to peripheral blood and later into B cell areas of spleen, thymus and cecal tonsils. The results are also discussed on the basis of their implication for the generation of antibody diversity in the chicken bursa.
Noradrenaline‐evoked cation conductance recorded with the nystatin whole‐cell method in rabbit portal vein cells.

1. Noradrenaline‐evoked currents were studied with the perforated patch technique (nystatin in the patch pipette) in freshly dispersed rabbit portal vein cells. 2. With potassium‐containing solutions noradrenaline produced an inward current at ‐50 mV and an outward current (IK(Ca] at 0 mV. In potassium‐free conditions noradrenaline elicited two distinct membrane currents which could be differentiated according to their sensitivity to the presence of caffeine in the bathing solution. One current was blocked whereas the second response was unaffected by caffeine. 3. The reversal potential (Er = ‐2.0 mV) of the caffeine‐sensitive current was altered when external chloride was replaced with more permeant anions but Er was not changed when external sodium was replaced by Tris. Therefore the caffeine‐sensitive current appears to be a calcium‐activated chloride current (ICl(Ca]. 4. Er (+6.0 mV) of the caffeine‐insensitive current was not altered by anion substitution but was changed when external sodium was replaced by Tris and barium ions. Thus the caffeine‐insensitive conductance is a non‐selective cation current (Icat). 5. When external NaCl was replaced by BaCl2, Er was shifted to more positive potentials which suggests that the cation conductance is more permeable to barium than to sodium. Icat was not affected by 10(‐6) M‐nifedipine. 6. The steady‐state current‐voltage relationship was linear between ‐50 and +50 mV for ICl(Ca) but the cation conductance mechanism displayed pronounced inward rectification and little outward current flowed across the membrane at positive potentials. 7. Caffeine (which releases calcium from internal stores) and the calcium ionophore ionomycin, which are expected to increase intracellular calcium concentration, evoked ICl(Ca) but not Icat. Thus ICl(Ca) but not Icat can be activated directly by an increase in intracellular calcium concentration. 8. When calcium was removed from the bathing solution the amplitude of Icat was not altered at early times in Ca(2+)‐free conditions but was abolished after 10 min. Icat was readily activated by noradrenaline in the presence of ionomycin, which inactivated ICl(Ca). A permissive role for calcium in the generation of Icat is suggested. 9. The times between the application of noradrenaline and the onset of the chloride and cationic conductances were similar (0.75 and 0.9 s respectively). In contrast the rise time (3.9 s) and half‐decay time (11 s) of Icat were much longer than the corresponding values of ICl(Ca) (respectively 1.9 and 2 s). In high‐barium solution noradrenaline sometimes evoked a response that lasted for up to 10 min.(ABSTRACT TRUNCATED AT 400 WORDS)
Diets for Disease? Intraurban Variation in Reported Food Consumption in Glasgow

A recent official report on the Scottish Diet reviews evidence for poor health and poor diets among the Scots, and makes extensive and specific recommendations about dietary change. This paper examines the extent to which reported consumption of fifteen of the food groups discussed in that report vary among four neighbourhoods in Glasgow City. Some foods appear to be typical of a wider Glaswegian (or Scottish) diet and show little variation among neighbourhoods (e.g. semi-skimmed milk, white fish, confectionery, cakes and pastries, savoury snacks). Other foods however show marked differences between neighbourhoods after controlling for sex, age and social class; these include fruit, vegetables, meat (particularly processed meat products), bread, spreading fats, sugar, natural fruit juice and alcohol. This suggests that such intraurban variations in food consumption cannot be explained simply by socio-demographic or socio-economic factors in individuals and that cultural and supply factors also need to be taken into account.
Identifying Sources of Resistance to Aflatoxin and Fumonisin Contamination in Corn Grain

Researchers at the University of Illinois seek to identify sources of genetic resistance that contribute alleles for low aflatoxin and low fumonisin accumulation in grain and low severity of Aspergillus and Fusarium ear rots to commercial corn (Zea mays L.) inbreds. Studies of resistance to aflatoxin accumulation in grain and Aspergillus ear rot began in 1988 with experiments designed to address fundamental needs of a new breeding program. Through the 1990s, diverse inbred lines, test crosses, and segregating populations were developed and evaluated for resistance in numerous environments. Concerns of industry inspired researchers to initiate an accelerated program for resistance to fumonisin accumulation in grain and Fusarium ear rot in the late 1990s. Present research in both programs is directed with the latest molecular marker technology, and is focused on incorporating novel genes for resistance from diverse sources into elite inbred lines that impart high yield to hybrid performance. With continued funding, agronomically superior sources of resistance along with information on molecular markers associated with resistance soon may be released.
Literature review of service restoration in distribution system

The structure of power system is changing around the world. With the increase in size and complexity of the distribution network, it is important to automate the system for proper monitoring and control. Service restoration is one of the techniques used by utilities to supply the power to healthy part of the network which gets isolated after occurrence of fault. The restoration plans have changed over the years to cope up with this changing nature of power system. A vast change is observed in methods, strategies used for service restoration. In this paper, review of different methods which are proposed to solve service restoration problem is presented which includes knowledge based systems, expert systems, heuristic methods, artificial intelligence techniques with search algorithm, hybrid methods like combining fuzzy logic method with Genetic Algorithm (GA), expert system and coloured petri nets etc., and different guidelines formed.
Genetic risk mechanisms of posttraumatic stress disorder in the human brain

Posttraumatic stress disorder (PTSD) follows exposure to a traumatic event in susceptible individuals. Recently, genome‐wide association studies have identified a number of genetic sequence variants that are associated with the risk of developing PTSD. To follow up on identifying the molecular mechanisms of these risk variants, we performed genotype to RNA sequencing–derived quantitative expression (whole gene, exon, and exon junction levels) analysis in the dorsolateral prefrontal cortex (DLPFC) of normal postmortem human brains. We further investigated genotype–gene expression associations within the amygdala in a smaller independent RNA sequencing (Genotype‐Tissue Expression [GTEx]) dataset. Our DLPFC analyses identified significant expression quantitative trait loci (eQTL) associations for a “candidate” PTSD risk SNP rs363276 and the expression of two genes: SLC18A2 and PDZD8, where the PTSD risk/minor allele T was associated with significantly lower levels of gene expression for both genes, in the DLPFC. These eQTL associations were independently confirmed in the amygdala from the GTEx database. Rs363276 “T” carriers also showed significantly increased activity in the amygdala during an emotional face‐matching task in healthy volunteers. Taken together, our preliminary findings in normal human brains represent a tractable approach to identify mechanisms by which genetic variants potentially increase an individual's risk for developing PTSD. © 2016 Wiley Periodicals, Inc.
Effects of walnuts on serum lipid levels and blood pressure in normal men.

BACKGROUND In a recent six-year follow-up study, we found that frequent consumption of nuts was associated with a reduced risk of ischemic heart disease. To explore possible explanations for this finding, we studied the effects of nut consumption on serum lipids and blood pressure. METHODS We randomly placed 18 healthy men on two mixed natural diets, each diet to be followed for four weeks. Both diets conformed to the National Cholesterol Education Program Step 1 diet and contained identical foods and macronutrients, except that 20 percent of the calories of one diet (the walnut diet) were derived from walnuts (offset by lesser amounts of fatty foods, meat, and visible fat [oils, margarine, and butter]). RESULTS With the reference diet, the mean (+/- SD) serum values for total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol were, respectively, 182 +/- 23, 112 +/- 16, and 47 +/- 11 mg per deciliter (4.71 +/- 0.59, 2.90 +/- 0.41, and 1.22 +/- 0.28 mmol per liter). With the walnut diet, the mean total cholesterol level was 22.4 mg per deciliter (0.58 mmol per liter) lower than the mean level with the reference diet (95 percent confidence interval, 28 to 17 mg per deciliter [0.72 to 0.44 mmol per liter]); the LDL and HDL cholesterol levels were, respectively, 18.2 mg per deciliter (0.47 mmol per liter) (P < 0.001) and 2.3 mg per deciliter (0.06 mmol per liter) (P = 0.01) lower. These lower values represented reductions of 12.4, 16.3, and 4.9 percent in the levels of total, LDL, and HDL cholesterol, respectively. The ratio of LDL cholesterol to HDL cholesterol was also lowered (P < 0.001) by the walnut diet. Mean blood-pressure values did not change during either dietary period. CONCLUSIONS Incorporating moderate quantities of walnuts into the recommended cholesterol-lowering diet while maintaining the intake of total dietary fat and calories decreases serum levels of total cholesterol and favorably modifies the lipoprotein profile in normal men. The long-term effects of walnut consumption and the extension of this finding to other population groups deserve further study.
A gene immune detection algorithm with a strategy of DNA PRI

Biological immune principles provide the perfect protecting schemes for computer immune system. Based on the research on anomaly detection, a gene immune detection algorithm is presented. Innate immune mechanism and adaptive immune mechanism of the biological immune system are considered synthetically. Positive selection and vaccine mechanism are introduced and a strategy of PRI in the detection is adopted by using gene detection. As shown in the simulation experiments, the algorithm improves the variety of the antibodies. It has a rather high detecting efficiency.
Parallel Depth-First Search for Directed Acyclic Graphs

Depth-First Search (DFS) is a pervasive algorithm, often used as a building block for topological sort, connectivity and planarity testing, among many other applications. We propose a novel work-efficient parallel algorithm for the DFS traversal of directed acyclic graph (DAG). The algorithm traverses the entire DAG in a BFS-like fashion no more than three times. As a result it finds the DFS pre-order (discovery) and post-order (finish time) as well as the parent relationship associated with every node in a DAG. We analyse the runtime and work complexity of this novel parallel algorithm. Also, we show that our algorithm is easy to implement and optimize for performance. In particular, we show that its CUDA implementation on the GPU outperforms sequential DFS on the CPU by up to 6x in our experiments.
Covalently Attached Vancomycin Provides a Nanoscale Antibacterial Surface

Despite improved strategies for treating periprosthetic infection, current antibiotic delivery approaches are imperfect and can result in bacterial resistance and recalcitrant bio-films. To address the issues, we developed a covalently linked vancomycin-titanium implant interface that prevents and possibly eliminates bacterial colonization. We determined the amount of vancomycin immobilized on the titanium surface and assessed vancomycin stability and activity over time. When incubated with Staphylococcus aureus, the vancomycin-titanium surface showed an almost complete absence of adherent bacteria. To determine if continual exposure to vancomycin-titanium would cause decreased susceptibility to the antibiotic, S. aureus was incubated with vancomycin-titanium for 1 week or 4 weeks; these bacteria did not show an increased minimum inhibitory concentration for vancomycin. We tested the long-term stability of the vancomycin-titanium surface by incubation in phosphate-buffered saline for 11 months and then challenging the surface with S. aureus. Fluorescent staining for bacteria indicated the vancomycin-titanium retained its bactericidal activity. Finally, osteoblasts seeded on the vancomycin-titanium surface exhibited no change in viability, indicating the surface supports bone cell adhesion. Based on these observations, covalent modification of the titanium surface with an antibiotic may be viewed as a potential new tool in preventing or eliminating periprosthetic infection.
A metric for evaluating software architecture and communication models consistency

Among several alternative viewpoints for building software quality metrics, evaluating the consistency between different models in a software specification or implementation appears to be fruitful. An obvious difficulty is that different models are usually expressed by means of different concepts, and then, confronting heterogeneous representations is not straightforward. In this paper, we propose a solution for measuring the consistency between the architecture and the communication models. After some sensible transformations, the information about both models are captured trough hierarchical representations. We define and discuss a similarity measure between hierarchies, that eventually founds the software metric we propose. Lastly, we investigate how to scale and interpret the metric values and give an application example with SDL.
Genetic Risk Factors for Periodontitis in a Japanese Population

Genetic variants at multiple loci have been shown to be associated with susceptibility to periodontitis. To better assess the genetic risk factors for periodontitis, we performed a case-control study in 319 Japanese individuals with periodontitis (172 aggressive and 147 chronic disease) and 303 race-matched healthy control individuals. Thirty-five functional gene polymorphisms that had been previously associated with immune responses were genotyped. For all gene polymorphisms tested, no significant differences were observed in the allele frequencies of persons with aggressive, chronic, and combined (aggressive and chronic) periodontitis, compared with control individuals. Multiple logistic regression analysis revealed a significant association of the vitamin D receptor +1056 T/C polymorphism with susceptibility to chronic periodontitis, after adjustment for age, gender, and smoking status (P = 0.002). These results suggest that none of the polymorphisms tested was strongly associated with periodontitis in a Japanese population. However, the vitamin D receptor +1056 polymorphism may be related to chronic periodontitis.
Mutation of recF, recJ, recO, recQ, or recR improves Hfr recombination in resolvase-deficient ruv recG strains of Escherichia coli

The formation of recombinants in Hfr crosses was studied in Escherichia coli strains carrying combinations of genes known to affect recombination and DNA repair. Mutations in ruv and recG eliminate activities that have been shown to process Holliday junction intermediates by nuclease cleavage and/or branch migration. Strains carrying null mutations in both ruv and recG produce few recombinants in Hfr crosses and are extremely sensitive to UV light. The introduction of additional mutations in recF, recJ, recO, recQ, or recR is shown to increase the yield of recombinants by 6- to 20-fold via a mechanism that depends on recBC. The products of these genes have been linked with the initiation of recombination. We propose that mutation of recF, recJ, recO, recQ, or recR redirects recombination to events initiated by the RecBCD enzyme. The strains constructed were also tested for sensitivity to UV light. Addition of recF, recJ, recN, recO, recQ, or recR mutations had no effect on the survival of ruv recG strains. The implications of these findings are discussed in relation to molecular models for recombination and DNA repair that invoke different roles for the branch migration activities of the RuvAB and RecG proteins.
