Electromyography and Fos immunostaining study establish a possible functional link between trigeminal proprioception and the oculomotor system in rats

The objective of this study was to explore whether there was a functional link between trigeminal proprioception and the oculomotor system mediated through jaw muscle afferents. Electromyography (EMG) was undertaken of the levator palpebrae (LP) and superior rectus (SR), and Fos expression was detected in the brainstem following consecutive down-stretching of the lower jaw at 2-4 Hz in rats. Retrograde tracing was undertaken of the interstitial nucleus of Cajal and Darkschewitsch nucleus (INC/DN) pre-oculomotor neurons. EMG-like responses were recorded from the LP/SR during down-stretching of the lower jaw at 2-4 Hz in 3 out of 11 rats. Fos expression was induced by consecutive down-stretching of the lower jaw at 2-4 Hz for 20-30 seconds. Interestingly, Fos expression was distributed mainly in the bilateral INC/DN area. We also examined Fos-like immunoreactivity in central mesencephalic and paramedian pontine reticular formation that harbors premotor neurons controlling horizontal eye movement, but no Fos-like staining was observed therein. By injection of retrograde tracers into the oculomotor nucleus combined with Fos immunostaining, double labeled pre-oculomotor neurons were visualized to distribute in the INC/DN. In conclusions, there may exist a trigeminal proprioceptive – oculomotor system neural circuit through jaw muscle afferents in rats. Judging from Fos distribution pattern, this pathway might be related to vertical and torsional eye movements.
Option Hedging in the Presence of Jump Risk

We examine Schweizer s locally risk minimizing LRM hedge approach for hedging a European call in the case when the stock price follows a Poisson jump di usion process with lognormally distributed jump sizes In contrast to Merton s hedging strategy where di usion risk is perfectly hedged while jump risk remains un hedged the locally risk minimizing strategy hedges both di usion risk as well as jump risk partly The hedge ratio consists of a di usion component and a jump component The value of the LRM hedge portfolio is equal to the discounted expected terminal payo of the option weighted with a so called minimal martingale density It is a weighted sum of Black Scholes values where some weights may be negative The latter property is due to our result that the minimal martingale density is negative with positive probability if e g the market price of risk is positive However introducing a single call does not admit arbitrage opportunities if its value is smaller than the underlying stock price and larger than the Black Scholes value based on the di usion volatility We relate the LRM approach to the so called locally variance minimizing LVM hedging strategy in Bates systematic jump risk model By numerical analysis we nd that the LRM and LVM hedge ratios are less sensitive to changes in the stock price than delta hedging strategies in the models of Merton Black Scholes and Bates If the expected jump size is signi cantly di erent from zero and positive negative then the LRM and LVM hedge ratios are substantially larger smaller than e g Merton s for out of the money in the money calls Moreover the worst case behaviour of the LRM strategy and LVM strategy are substantially better The as well as the quantile of the total hedging costs are signi cantly lower than for the alternative strategies
Fast Recursive Algorithm for Efficient Transmit Antenna Selection in Spatial Multiplexing Systems

In this paper we propose fast and efficient transmit antenna selection algorithms for wireless spatial multiplexing (SM) systems with linear receivers. Motivated by matrix inverse properties, a recursive matrix inverse calculation is developed for fast transmit antenna selection. Two selection criteria are proposed based on the recursive matrix inverse updating: one is the minimum mean square error (MMSE) and another is the maximum signal to interference noise ratio (SINR). Different from the conventional optimal antenna selection algorithms, the proposed algorithms are capable of computing matrix inverse and selection criteria from the previous computational results via a simple recursive procedure, so that the algorithmic complexity is reduced significantly. Simulation results show that our algorithms perform very close to the optimal exhaustive search algorithms in terms of bit error rate and capacity in both uncorrelated and highly correlated MIMO channels, while the computational complexity is much lower.
Expanding bandwidth of class-F power amplifier with harmonic structures

This paper presents a methodology for designing compact broad-band RF power amplifiers with stretched harmonic tuning output networks. Rather than adopting a conventional output matching for wideband class-F operations, which is bulky in its size, this paper suggests a simpler way to achieve small-sized but wideband class-F operation. The proposed idea is achieved by stretched harmonic tuning circuits, and is verified by implementing a power amplifier at 1.9 GHz with a 10 W GaN HEMT transistor. It showed 50 % of drain efficiency over the bandwidth of 250 MHz with significantly smaller size than the conventional continuous-mode class-F designs. The maximum output power is 14.45 W and a peak gain is 12.9 dB at 1.9 GHz.
Combined experimental and theoretical study on the removal of pollutant compounds by peroxidases: affinity and reactivity toward a bioremediation catalyst

Water pollution is a significant and growing problem throughout the world, especially in developing countries. In order to minimize environmental problems, catalysts have increasingly been designed to remove pollutants from the water. In an attempt to innovate by the creation of new low-cost alternatives to efficiently remove pollutants, the enzymatic treatment has been intensely studied for this purpose. Reactions catalyzed by enzymes are able to perform specific treatments, commonly with high rates of the final products. With this, the enzyme, peroxidase, is a promising candidate as a bioremediation catalyst. The efficiency of oxidoreductive enzymes, such as horseradish peroxidase (HRP) and soybean peroxidase (SP) have been studied, given that their performance depends on the substrate. In this investigation, experimental techniques and theoretical calculations have been employed in order to investigate the oxidative process for the ferulic acid and bromophenol blue dyes, performed by HRP and SP. Both enzymes showed a comparable behavior with respect to ferulic acid substrate. On the other hand, by utilizing bromophenol blue dye as a substrate, the behavior of the employed catalysts was significantly different. Experimental data have shown that HRP was more active toward bromophenol blue when compared to ferulic acid, being more rapidly degraded by the HRP enzyme. This tendency was confirmed by our theoretical docking, PM6 semi-empirical method, and DFT calculation results, in which the interaction, binding energies, and transition states were determined.
Constipation and Biofeedback Important Gastrointestinal Symptom but Ignored Initial Management

Constipation is the most common digestive complaint in the general population and its etiology is diverse. Defecatory disorder is a common type of constipation where the patient has difficulty during evacuation due to ineffective relaxation of the anal sphincter and/or inadequate abdominal push. Biofeedback therapy for constipation is a technique used to train a patient’s mind to control the way their anorectum works. Biofeedback therapy is unfortunately not available in many centers and also not widely recommended by the physicians although its response rate in the treatment of constipation is about 70-80%. Here, the constipation and biofeedback therapy are shortly reviewed under the light of recent literature and, our study observing the percentage of patients who performed BFT in real world upon recommendation and its clinical response rate in our center for anorectal disease as well as the barriers to biofeedback is discussed.
Self‐managing teams

Proliferation of advanced production technology and challenging competition created by the increasing internationalization of business activities have placed great emphasis on production quality and customer satisfaction. Quality improvement, cost cutting, and profit maximization are critical strategies for coping with the rapidly changing environment of the 1990s. Effective blending of these strategies can be achieved through employing advanced philosophies of production management: total quality management, workforce activity‐based management, or quality of work life. Reviews these philosophies and examines the criteria that contribute to a successful implementation programme as demonstrated in one facility of the world’s largest producer of paper‐machine “clothing”. Concludes by identifying factors that should be considered when designing a model for total quality management. The model emphasizes the integration of the autonomous team concept and the sociotechnical approach of organizational design as .
In vitro and in vivo study on the effect of antifungal agents on hematopoietic cells in mice

Liposomal amphotericin B, voriconazole, and caspofungin are currently used for systemic and severe fungal infections. Patients with malignant diseases are treated with granulocyte-colony stimulating factor (G-CSF) for the recovery of granulocytes after chemotherapy or hematopoietic cell (HC) transplantation. Since they have a high incidence of fungal infections, they inevitably receive antifungal drugs for treatment and prophylaxis. Despite their proven less toxicity for various cell types comparatively with amphotericin B and the decrease in the number of leukocytes that has been reported as a possible complication in clinical studies, the effect of liposomal amphotericin B, voriconazole, and caspofungin on HCs has not been clarified. The present study aimed to examine the in vitro and in vivo effect of these three modern antifungals on HCs. Colony-forming unit (CFU) assays of murine bone marrow cells were performed in methylcellulose medium with or without cytokines and in the presence or absence of various concentrations of liposomal amphotericin B, voriconazole, and caspofungin. In the in vivo experiments, the absolute number of granulocytes was determined during leukocyte recovery in sublethally irradiated mice receiving each antifungal agent separately, with or without G-CSF. In vitro, all three antifungal drugs were nontoxic and, interestingly, they significantly increased the number of CFU-granulocyte-macrophage colonies in the presence of cytokines, at all concentrations tested. This was contrary to the concentration-dependent toxicity and the significant decrease caused by conventional amphotericin B. In vivo, the number of granulocytes was significantly higher with caspofungin plus G-CSF treatment, higher and to a lesser extent higher, but not statistically significantly, with voriconazole plus G-CSF and liposomal amphotericin B plus G-CSF treatments, respectively, as compared with G-CSF alone. These data indicate a potential synergistic effect of these antifungals with the cytokines, in vitro and in vivo, with subsequent positive effect on hematopoiesis.
Thermal Vehicle-Concept Study Using Co-Simulation for Optimizing Driving Range

Heating in winter can reduce the maximum driving range of electric vehicles by about 50%. Therefore, thermal management is currently a big issue in this sector. This contribution shows the development and implementation of an entire vehicle model which is capable of investigating novel concepts for increasing the maximum driving range of electric vehicles. Therefore, a co-simulation interface between two simulation tools is created. The developed virtual environment is then used to simulate and optimize the energy efficiency of an electric reference vehicle by investigating different thermal management concepts.
Modèles de mémoires pour la navigation autonome

Nous proposons une approche du probleme de la navigation d'un agent autonome fondee sur une architecture connexionniste inspiree de donnees biologiques concernant le cortex cerebral et l'hippocampe, une sous-structure corticale. Notre approche se fonde sur la distinction des memoires, le cortex cerebral etant fortement implique dans la memoire procedurale, permettant l'apprentissage de procedures, alors que l'hippocampe est implique dans la memoire declarative, permettant la memorisation explicite de faits et d'evenements. Notre travail concerne la mode- lisation de ces memoires dans le contexte du comportement autonome. L'etude des dfferentes memoires met en evidence l'importance de cette dichotomie procedurale/declarative dans les tâches cognitives et l'etude de la navigation autonome met en exergue la notion de carte cognitive topologique ainsi que la necessite de disposer de systemes de memoires adequats. Notre travail de modelisation s'articule alors en deux temps. Les donnees concernant le cortex humain ont permis de modeliser une memoire procedurale pour la construction des liens reliant les differents lieux d'un environnement simule permettant une recherche guidee par le but ainsi que le ralliement a tout instant d'un lieu visite auparavant. Par ailleurs, les differentes donnees concernant la structure de l'hippocampe ont permis de proposer un modele de memoire de type declaratif. L'architecture de ce modele ainsi que les mecanismes originaux participant a son fonctionnement lui assurent une efficacite et une robustesse aussi bien sur des donnees simulees que sur des donnees reelles. Ce modele permet alors de caracteriser de facon adequate les differents lieux d'un environnement donne.
Monetary Integration and the Cost of Borrowing

With the beginning of the European Monetary Union (EMU), euro-area sovereign securities adjusted spreads over Germany (corrected from the foreign exchange risk) experienced an increase that caused a lower than expected decline in borrowing costs. The objective of this paper is to study what explains that rising. In particular, if it took place a change in the price assigned by markets to domestic (credit risk and/or market liquidity) or to international risk factors. The empirical evidence supports the idea that a change in the market value of liquidity occurred with the EMU. International and default risk play a smaller role.

SwissPIT: An workflow‐based platform for analyzing tandem‐MS spectra using the Grid

The identification and characterization of peptides from MS/MS data represents a critical aspect of proteomics. It has been the subject of extensive research in bioinformatics resulting in the generation of a fair number of identification software tools. Most often, only one program with a specific and unvarying set of parameters is selected for identifying proteins. Hence, a significant proportion of the experimental spectra do not match the peptide sequences in the screened database due to inappropriate parameters or scoring schemes. The Swiss protein identification toolbox (swissPIT) project provides the scientific community with an expandable multitool platform for automated in‐depth analysis of MS data also able to handle data from high‐throughput experiments. With swissPIT many problems have been solved: The missing standards for input and output formats (A), creation of analysis workflows (B), unified result visualization (C), and simplicity of the user interface (D). Currently, swissPIT supports four different programs implementing two different search strategies to identify MS/MS spectra. Conceived to handle the calculation‐intensive needs of each of the programs, swissPIT uses the distributed resources of a Swiss‐wide computer Grid (http://www.swing‐grid.ch).
DNA sequence and transcriptional organization of essential cell division genes ftsQ and ftsA of Escherichia coli: evidence for overlapping transcriptional units

The DNA sequence of a cloned segment of the Escherichia coli chromosome containing ftsQ, ftsA, and part of the ftsZ gene was determined and interpreted for genetic complementation and promoter fusion data for the region. The contiguous genes ftsQ, ftsA, and ftsZ were transcribed in the same direction (clockwise on the genetic map) and each had at least one associated promoter which allowed it to be transcribed independently of neighboring genes. ftsA and ftsZ possessed promoters within the coding sequences of the juxtaposed upstream structural genes, and a promoter element for ftsA was surrounded by a region of twofold symmetry which corresponded closely to a symmetrical element in the region of a putative ftsZ promoter. The structural gene of ftsQ consisted of 838 nucleotides, encoding a 276-residue amino acid polypeptide of molecular weight 31,400; the structural gene of ftsA consisted of 1,260 nucleotides, encoding a 420-residue amino acid polypeptide of molecular weight 45,400. The observation that the termination codon of ftsQ overlaps with a potential initiation codon for ftsA suggested that these two genes may be translationally coupled when transcription is initiated upstream of the ftsQ coding sequence.
Searching for studies for inclusion in Cochrane Systematic Reviews on injury prevention

The Cochrane Injuries Group (CIG) prepares and maintains Cochrane Systematic Reviews of interventions for the prevention, treatment, and rehabilitation of traumatic injury. In this edition of Cochrane Corner, we describe how to search for studies to be included in a systematic review. Researchers and policy makers may also find these strategies useful when conducting general literature reviews on injury topics. An adequate search is key to ensuring high quality of the resultant review. To achieve the aim of identifying all relevant evidence, sophisticated information searching techniques are required. It is, however, a challenge to devise a search strategy with the appropriate balance between sensitivity and specificity; a sensitive search is required in order to identify as much of the relevant evidence as possible, yet specificity is required to ensure that the review author is not forced to wade through extensive amounts of irrelevant information. Search methods for every review need careful consideration to ensure that eligible studies are not missed or rejected, which could compromise the review’s findings. Injury prevention reviews pose a particular challenge when it comes to searching, as much of the relevant evidence is present in sources that are not indexed on the major databases such as Medline, EMBASE, and PubMed. Thus, searching of other, sometimes less standard, resources is an important part of conducting such a review. For example, authors of some of the CIG’s interventions for road safety reviews have found that much relevant evidence can be identified from general internet searches and websites of related institutions such as the National …
Conceptualizing Web-Based Stakeholder Communication: The Organizational Website as a Stakeholder Relations Tool

With the near ubiquity of the organizational website, organizations’ online stakeholder relationships have dramatically increased in prevalence, complexity, and financial and strategic importance. To help advance our understanding of these relationships, we introduce and test the multi-dimensional concept of Web-based stakeholder communication using original data on US community foundations. After presenting the conceptual foundations of Web-based stakeholder communication, we develop operational measures of its key dimensions, namely stakeholder targeting and the balance of organizations’ online stakeholder portfolios. We then explore the outcomes of Web-based stakeholder communication by testing for its relationship to subsequent levels of charitable contributions. We end with an in-depth discussion of the most important implications for organizational theory and practice.
Microgrid frequency stabilization using model predictive controller

A reliable and economical/green microgrid is the major focus area of the modern power system. These are operating as controllable system either singly in isolated mode or collectively in grid connected mode. The reliability of the microgrid is a major concern which is threatened by the load fluctuations and intermittent renewable energy penetration. This paper presents the frequency stabilization in a microgrid under solar penetration and load fluctuation. This microgrid frequency stabilization is based on model predictive controller (MPC). The battery energy storage (BES) with charging/discharging and its controlled state of charge (SoC) is used for primary frequency control. The frequency prediction is also carried out in order to enhance the performance of the MPC controller. A comparison between the PI controller and MPC is made for frequency deviation in MATLAB/Simulink environment. The simulation results depict the effectiveness of the MPC in frequency stabilization.
