Expression of a cell surface antigen from Rhizobium leguminosarum 3841 is regulated by oxygen and pH

Rhizobium leguminosarum bv. viciae 3841 was grown in liquid suspension culture to investigate how culture conditions could affect the expression of a developmentally regulated cell surface antigen associated with lipopolysaccharide. The antigen, which is recognized by monoclonal antibody AFRC MAC 203, was expressed when cultures were grown at neutral pH under low-oxygen conditions (less than 7.5% [vol/vol] O2 in the gas phase). Antigen was also expressed in aerobically grown cultures at pH values below 5.3. The nature of the nitrogen and the carbon sources had no effect on antigen expression except by indirect changes on the pH of the culture medium; similarly, growth in 0.3 M NaCl did not result in antigen expression. The induction of MAC 203 antigen by low-oxygen or low-pH culture conditions is discussed in the context of tissue-specific expression within the legume root nodule.
Energy Efficient Anchor-Based Localization Algorithm for WSN

Localization is one of the most fundamental problems in wireless sensor networks, since the locations of the sensor nodes are critical to both network operations and most application level tasks. To solve the localization problem for find out the location of sensor nodes in wireless sensor network, a Anchor based localization scheme for wireless sensor networks with energy efficiency is presented in this thesis. First, we develop a standardized clustering-based approach for the local coordinate system formation wherein a multiplication factor is introduced to regulate the number of cluster head nodes and neighbor nodes and the degree of connectivity among cluster head nodes. The algorithm operates asynchronously without a centralized controller; and in this algorithm location of the cluster heads be known a priori which are called anchor nodes. In this thesis to calculate the distance between the nodes triangulation technique is used. A simulation analysis on a specific numerical example is conducted for specifying the energy efficiency in finding the location by using anchor nodes. Experiments show that our algorithm beneficiary for less energy consumption.
RELATING RESOURCES TO A PROBABILISTIC MEASURE OF SPACE USE: FOREST FRAGMENTS AND STELLER'S JAYS

Many analytical techniques that assess resource selection focus on individual relocation points as the sample unit and classify resources as either used or available. Commonly, the relative use of each resource is quantified as the number of observations in each resource class or the proportional occurrence of a resource within a home range. We believe that a more accurate estimate can be summarized by a utilization distribution (UD). We present an analytical approach that explicitly incorporates a probabilistic measure of use, as defined by the UD. We used animal relocation points and fixed-kernel techniques to determine a UD within a home range. We related this probabilistic measure of use to categorical and continuous resource variables using multiple regression. Regression errors accounted for spatial autocorrelation so that the significance of regression coefficients could be appraised for each animal and averaged across animals. This allowed us to quantify the individualistic nature of resource sele.
Plasmonic ship-wake on graphene

Kelvin predicted that the semi-angle of the V-shaped wedge behind a ship moving in deep water region is 19.5°, independent of the ship's velocity. The predication has been challenged recently that the semi-angle would transit from the Kelvin angle to the Mach angle as the ship's velocity increases. In this paper, we show the graphene plasmons excited by a swift charged particle would have the similar phenomenon. When the velocity of the charged particle is relatively slow, the graphene plasmons excited would accumulate along the caustic boundary of the graphene plasmons pattern, forming the plasmonic Kelvin angle. At large velocity, however, no graphene plasmons would accumulate along any boundary, thereby the caustics disappear and the effective semi-angle of the graphene plasmons approaches the Mach angle.
The simulation study on a PET system composed of hexagonal prism shaped scintillation crystals

The hexagonal prism shaped crystal shows potential to design a PET system for its higher ray blocking efficiency and equidistance with neighbors. This paper proposed a honeycomb PET based on hexagonal prism shaped scintillation crystals. Its performance was evaluated and compared with a traditional PET system based on rectangular prism shaped crystals by GEANT4 simulation. The results show that the sensitivity is enhanced from 2% to 5% in most positions of the field of view (FOV). Meanwhile, the axial, radial and tangential spatial resolution are both improved in the positions near the center of the FOV (0mm, 10mm radial offset), but deteriorated with the offset become larger.
Measurement of changes in cell volume based on fluorescence quenching.

The intracellular fluorescence of 6-methoxy-N-(3-sulfopropyl)-quinolinium (SPQ), a Cl(-) -sensitive fluorescent dye, is quenched by intracellular organic anions and proteins of unknown identity. The concentration of these intracellular quenchers (ICQs), however, is dependent on cell volume. In the absence of Cl-, changes in the observed SPQ fluorescence may therefore reflect changes in cell volume. This concept has been applied to determine relative changes in cell volume of cultured corneal endothelium in response to anisosmotic shocks, using NO3- as the Cl- substituent. SPQ fluorescence increased with decreasing osmolarity and vice versa. A 20 mosM hypertonic shock was needed to detect a change in SPQ fluorescence with a signal-to-noise ratio of >25. Assuming dynamic quenching by ICQs, we applied an extension of the Stern-Volmer equation to develop a simple relationship between the measured SPQ fluorescence and relative changes in cell volume. For large hyposmotic shocks, regulatory volume decrease (RVD) was observed. The rate of RVD could be enhanced by exposure to 0.5 microM gramicidin in low-Na+ Ringer solution (i.e., K+-NO3- efflux), indicating that K+ conductance is rate limiting for RVD. These results demonstrate the principle of using fluorescence quenching to measure changes in cell volume in real time. Because SPQ is sensitive to Cl-, its usefulness as a quenching probe is limited. However, a structure-activity study can be expected to yield useful Cl(-)-insensitive analogs.
Research on ion implanter transferring from spot beam to ribbon beam

With efficient DOE method, we figure out the regression equations for overall devices by dose scalar only and successfully transfer SDE and SD ion implantation from spot beam batch type to parallel ribbon beam single type ion implanter in sub-100nm CMOS process. Using the regression equations, the process window is clear expressed. That helps us to understand and well control related processes.
Fibrillation of muscle fibers produced by ammonium ions and its relation to the spontaneous activity at the neuromuscular junction.

1. Effects of NH4+on the isolated muscle of frog and toad were studied. Chiefly, sartorius muscle was used. When the muscle is immersed in NH4+ Ringer, discharge frequency of miniature e.p.p. increases very much and at the same time fibrillations of muscle fibers are produced. Effects of NH4+ appears with a delay.2. Fibrillations due to NH4+is completely suppressed by tubocurarine and can not be suppressed by tetrodotoxin. It is concluded that the augmentation of discharge frequency of miniature e.p.p. is the cause of the fibrillation.3. Fibrillation from this origin can not be produced by K+, though discharge frequency is increased by K+. Possible causes of the difference were discussed.
Evaluation of a Triplex PCR Assay To Discriminate Staphylococcus aureus from Coagulase-Negative Staphylococci and Determine Methicillin Resistance from Blood Cultures

ABSTRACT A triplex PCR targeting the 16S rRNA, mecA, and nuc genes was developed for identification of staphylococci and detection of methicillin resistance. After validation of the assay with a collection of strains of staphylococci and enterococci (n = 169), the assay was evaluated with cultures of blood with gram-positive cocci from 40 patients. Accurate results were obtained for 59 (98%) of 61 cultures within 6 h of growth detection.
Aspiration biopsy of the spine.

At the present time aspiration biopsy of the vertebral bodies can be considered a routine procedure, a surgical technique definitely indicated for the diagnosis of skeletal lesions. Experience with 1078 aspiration biopsies of the vertebral bodies performed over the last twenty-eight years without complication substanitiates this opinion. Since my first publication in collaboration with Valls arid Schajowicz, many authors have used this method, modifying the original technique. Ellis, Meiss, Sicard and associates, Ray, Craig, Ackermanin, DeSeze and associates, Frankel, and others have made importanit contributions. The works of these authors confirm the advantages of aspiration biopsy of the spine. However, their modifications of both the technique and the instruments have not changed the main principles of the procedure. The simplicity of aspiration biopsy and its advantages in the diagnosis of bone lesions are substantiated by the fact that 4173 needle biopsies of lesions located in different skeletal regions, all recorded at the Latin-American Registry of Bone Pathology, have been performed since this method was first employed. In previous papers the advantages of aspiration biopsy of the spine arid the difficulties encountered were considered. The main technical points necessary for successful application of the method were described. I would again emphasize that the procedure is simple without risk for the patient provided the proper techniique is used. It permits one to reach deep structures that otherwise could only be approached by difficult surgical operations. Close cooperation between the orthopaedist arid the pathologist is of paramount. importance. The pathologist must have complete knowledge of the clinical, roemitgemiographic, and laboratory findings; lie must also be very competent in bone pathology. Preferably he should be present at the biopsy and should attend all orthopaedic clinical meetings. No pathological examination of a specimemi should be undertaken without concurremit review of the clinical record and the roentgenograms. The high percentage of positive results obtained at my hospital is the result of such close collaboration between the orthopaedic surgeons and the pathologist. The vertebral bodies are frequent sites of many different lesiomis and it is now generally agreed that it is difficult to make a definite diagnosis simply on the basis of the clinical features, laboratory tests, roentgenograms, tomograms, amid the like. However, I do not agree with Michele arid Krueger who have stated that to make an accurate diagnosis of a lesion of a vertebral body it is better to do an open operation using a posterior or amiterolateral approach. It is now clear that all vertebrae can be * Read at the Amimiual Meeting of The Americami Orthopaedic Association, Hot Springs, Virginia, June 28, 1967. t Professor of Orthopaedics and Traumatology, University of Buenos Aires, Buemios Aires, Argentina.
Antecedents to workplace injury in the health care industry: A synthesis of the literature

Background: The U.S. Department of Labor has identified the health care industry as a major source of all U.S. workplace injuries. Studies have shown that injury within the health care workforce is related to high turnover rates, burnout, poor job satisfaction, and leaving the health care workforce permanently, thus contributing to the existing health care workforce shortages. Purpose: The purpose of this synthesis of the literature was twofold. The first was to conduct a comprehensive evaluation of the occupational health and safety literature to determine the key antecedents to health care provider injury. The second was to utilize the National Institute for Occupational Safety and Health (NIOSH) framework to organize the findings. Methodology: Empirical studies published between 1985 and 2013 examining work-related injuries sustained by nurses and nurses’ aides were systematically reviewed and evaluated for inclusion in the synthesis of the literature. Thirty-six studies met the criteria for inclusion. Using the NIOSH framework, antecedent variables to workplace injury were identified and then grouped into three broad categories that were highlighted during the synthesis: organization of work, job characteristics, and safety programs and training. A fourth category, individual characteristics, was added based on its use by many studies. Findings: Over half of the studies (n = 20) included factors within the organization of work category. Over two thirds of the studies (n = 26) included job characteristics such as task and demand. Nine studies contained information related to safety programs and training, whereas 17 studies included information on individual factors. The findings suggest that the NIOSH framework, with the addition of individual characteristics, provide a foundation for conceptually organizing occupational health and safety studies. Practice Implications: Health care administrators and leaders should be aware and understand the antecedents to workplace injury that will assist their organizations in developing training programs to reduce the current excessive rates of health care provider injury.
Investigating Factors Affecting Electronic Word-Of-Mouth In The Open Market Context: A Mixed Methods Approach

Electronic Word-of-Mouth (eWOM) has been identified as one of key factors affecting online sales. There has been, however, lack of understanding about the factors leading to eWOM in the open market context. As many Internet vendors have adopted the open market business, it is essential to understand the factors leading to eWOM for the success of open market business. This study investigates factors affecting eWOM in the open market context based on a sequential combination of qualitative and quantitative research methods. The exploratory findings in the qualitative study become the basis for the quantitative study, survey research. The findings from the mixed methods explain the significance of three new factors (information sharing desire, self-presentation desire, and open market reward) and two other factors (open market satisfaction and open market loyalty) affecting eWOM directly and indirectly. This study contributes to research by adding to the broader literature on eWOM. The findings also can inform open market providers on how to promote and manage eWOM for their online business success.
Our healthier nation

At last we have a national public health policy firmly based on the glaring evidence that health depends on social, economic, and environmental policies as well as on individual lifestyles and health services. The government's green paper, Our Healthier Nation 1 sets out the case for concerted action to tackle not just the causes of disease but the causes of the causes: poverty, inequalities, social exclusion, unemployment, and all the other features of the physical and social environment that converge to undermine health.2 “Connected problems,” the paper tells us, “require joined-up solutions. ” The joining up is to be done via a three way “contract” between central government, local services, and the individual, where each will agree to play its part in improving the country's health while reducing health inequalities. Thus, under the Minister for Public Health, government bodies in all sectors are to be driven towards policies that help improve health. Partnerships between health and local authorities will solve local problems, each partner committing themselves to appropriate targets. The public are to be given more help and information, especially in schools, workplaces, and …

Encephalomyocarditis virus in a captive Malayan tapir (Tapirus indicus)

A 5-month-old female captive Malayan tapir (Tapirus indicus) died suddenly without preceding symptoms. Gross necropsy revealed numerous white circular and linear foci in the myocard. Differential diagnosis all turned out negative, except for encephalomyocarditis virus. Histopathology revealed mineralisation of myocardial cells and interstitial infiltration of lymphocytes, plasma cells and less neutrophils. Encephalomyocarditis virus was detected by PCR. Although encephalomyocarditis virus occurs in many mammals, this is the first published description of this virus in a Malayan tapir.

Design of a Parallel Actuated Exoskeleton for Adaptive and Safe Robotic Shoulder Rehabilitation

Powered exoskeletons can facilitate after-stroke rehabilitation of patients with shoulder disabilities. Designs using serial mechanisms usually result in complicated and bulky exoskeletons. This paper presents a new parallel actuated shoulder exoskeleton that consists of two spherical mechanisms, two slider crank mechanisms, and a gravity balancing mechanism. The actuators are grounded and placed side-by-side. Thus, better inertia properties can be achieved while lightweight and compactness are maintained. An adaptive mechanism with only passive joints is introduced to compensate for the exoskeleton–limb misalignment and size variation among different subjects. Linear series elastic actuators (SEAs) are proposed to obtain accurate force and impedance control at the exoskeleton–limb interface. The total number of force sensors and actuators is minimized using the adaptive mechanism and SEAs. An exoskeleton prototype is shown to provide bidirectional actuation between the exoskeleton and upper limb, which is required for various rehabilitation processes. We expect this design can provide a means of shoulder rehabilitation.
Studies on How Early Maternal Separation Produces Behavioral Change in Young Rats

&NA; Previously published studies point to the behavioral interaction between the mother and her litter as the origin of the processes responsible for the behavioral hyperactivity following maternal separation in 2‐week‐old rats. The following experiments explore (1) the time course over which behavioral hyperactivity develops, (2) environmental and social determinants, (3) the role of sensory stimulation in the regulation of behavior and (4) the olfactory sensory system as a mediator of separation effects. The hypotheses supported best by the data are (1) that tactile and olfactory stimulation repeatedly provided by the mother act to reduce levels of behavioral arousal of the infants and (2) that maternal separation exerts its effect by withdrawal of this regulating influence, allowing a new level of behavioral arousal, more intrinsic to the infant, to be revealed.
A direct visual-inertial sensor fusion approach in multi-state constraint Kalman filter

Pose estimation only using a monocular camera and an inertial sensor triggers increasing popularity in recent years. In this paper, we propose a method, that tightly combines direct image information (intensity and gradient) from monocular camera with inertial information from three-axis gyroscope and accelerometer in a multi-state constraint Kalman filter (MSCKF) based framework to perform an effective pose estimation. In contrast to other pose estimation methods using vision, our solution gets rid of traditional feature extraction and expression, instead using image patches with distinct gradient to represent a visual measurement from environment. We adopt sequential inertial information and the poses between two consecutive keyframes to construct the state vector, imposing constraints on the poses and marginalising out expired ones, which would reduce the computational complexity linear to the number of selected patches. Furthermore, we view the data from the inertial sensor as intrinsic information applied in filter propagation, providing fast rate estimation for the state. The result of our method has been tested on real flying data of a micro aerial vehicle in indoor and outdoor environments.

Tuning OpenCL Applications with the Periscope Tuning Framework

Due to the complexity and diversity of new parallel architectures automatic tuning of parallel applications has become increasingly important for achieving acceptable performance levels as well as performance portability. The European AutoTune project developed a tuning framework which closely integrates and automates performance analysis and performance tuning. The Periscope Tuning Framework relies on a flexible plugin mechanism providing tuning plugins for different tuning aspects. This paper presents plugins for tuning the execution time of OpenCL kernels on three different architectures, namely standard multicore CPUs, Xeon Phi coprocessors, and GPUs. We present OpenCL tuning via the flags used during offline kernel compilation as well as through the selection of the most appropriate NDRange configuration, which defines the organization of parallel threads used for kernel execution. Both tuning plugins show significant performance impact and a clear dependence on the target architecture and thus improve performance portability via automatic tuning.
Research on the control loop for Solid Vibratory Gyroscope

This work presents the design, analysis, simulation of the control loop of Solid Vibratory Gyroscope (SVG). It can be used to measure the angular velocity of a rotating body based on the inertia effect of the standing wave in two vibration modes of the axisymmetric resonator. In order to reduce the response time, increase the response bandwidth and improve the sensitivity, it is necessary to design the gyroscope control loop and control strategy. A theoretical analysis on the traditional SVG is performed based on the ring model. To realize easily, the implementation modal is given. The typical structure of SVG control includes eight elements which are equally distributed around the circumference. The novel control loop based on the liner demodulator is introduced. It achieves the mode shape stability vibration used the control loop throughout the phase and amplitude of x and y. The numerical simulation is presented to verify the effectiveness of the proposed control scheme using the HRG parameters.
