A Seiberg Dual for the MSSM: Partially Composite W and Z

We examine the possibility that the SU(2)L gauge group of the standard model appears as the dual \magnetic" gauge group of a supersymmetric gauge theory, thus the W and Z (and through mixing, the photon) are composite (or partially composite) gauge bosons. Fully composite gauge bosons are expected to interact strongly at the duality scale, and a large running is needed to match the electroweak gauge couplings. Alternatively one can mix the composite \magnetic" gauge bosons with some elementary ones to obtain realistic models. In the simplest and most compelling example the Higgs and top are composite, the W and Z partially composite and the light fermions elementary. The eective theory is an NMSSM-type model where the singlet is a component of the composite meson. There is no little hierarchy problem and the Higgs mass can be as large as 400 GeV. This \fat Higgs"-like model can be considered as an explicit 4D implementation of RS-type models with gauge elds in the bulk.
Full Cost, Profit and Competition

During the marginalist controversy, full costers failed to convince economists of the superiority of full cost pricing over marginal theory of imperfect competition. The controversy was closed prematurely; various contributions published immediately thereafter in the fifties did not renew the debate despite their relevance. Topics included entry prevention, target rate of profit and the emergence of the market price The present paper shows that the full cost pricing is not so justified by the need for a rule of thumb than as a rational behaviour aiming at long term profit maximisation, especially in the case of highly competitive markets with few suppliers. The paper focuses also on the relationship between full cost pricing and changes in demand (mostly cyclical). It is also shown that the race for performance deserves a central position in the analysis of competition; it is too often neglected in favour of the sole competition on margins.
Q-Cell Glioblastoma Resource: Proteomics Analysis Reveals Unique Cell-States Are Maintained in 3D Culture

Glioblastoma (GBM) is a treatment-refractory central nervous system (CNS) tumour, and better therapies to treat this aggressive disease are urgently needed. Primary GBM models that represent the true disease state are essential to better understand disease biology and for accurate preclinical therapy assessment. We have previously presented a comprehensive transcriptome characterisation of a panel (n = 12) of primary GBM models (Q-Cell). We have now generated a systematic, quantitative, and deep proteome abundance atlas of the Q-Cell models grown in 3D culture, representing 6167 human proteins. A recent study has highlighted the degree of functional heterogeneity that coexists within individual GBM tumours, describing four cellular states (MES-like, NPC-like, OPC-like and AC-like). We performed comparative proteomic analysis, confirming a good representation of each of the four cell-states across the 13 models examined. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis identified upregulation of a number of GBM-associated cancer pathway proteins. Bioinformatics analysis, using the OncoKB database, identified a number of functional actionable targets that were either uniquely or ubiquitously expressed across the panel. This study provides an in-depth proteomic analysis of the GBM Q-Cell resource, which should prove a valuable functional dataset for future biological and preclinical investigations.
The sparkling Universe: Clustering of voids and void clumps

We analyse the clustering of cosmic voids using a numerical simulation and the main galaxy sample from the Sloan Digital Sky Survey. We take into account the classification of voids into two types that resemble different evolutionary modes: those with a rising integrated density profile (void-in-void mode, or R-type) and voids with shells (void-in-cloud mode, or S-type). The results show that voids of the same type have stronger clustering than the full sample. We use the correlation analysis to define void clumps, associations with at least two voids separated by a distance of at most the mean void separation. In order to study the spatial configuration of void clumps, we compute the minimal spanning tree and analyse their multiplicity, maximum length and elongation parameter. We further study the dynamics of the smaller sphere that encloses all the voids in each clump. Although the global densities of void clumps are different according to their member-void types, the bulk motions of these spheres are remarkably lower than those of randomly placed spheres with the same radii distribution. In addition, the coherence of pairwise void motions does not strongly depend on whether voids belong to the same clump. Void clumps are useful to analyse the large-scale flows around voids, since voids embedded in large underdense regions are mostly in the void-in-void regime, were the expansion of the larger region produces the separation of voids. Similarly, voids around overdense regions form clumps that are in collapse, as reflected in the relative velocities of voids that are mostly approaching.
Leaf Litter Decomposition and Nutrient Dynamics Associated with Common Horticultural Cropland Agroforest Tree Species of Bangladesh

Mangifera indica, Zizyphus jujuba, Litchi chinensis, and Artocarpus heterophyllus are the most common cropland agroforest horticultural tree species of Bangladesh. This study focused on leaf litter decomposition and nutrient (N, P, and K) dynamics during the decomposition process. This experiment was conducted for 180 days by using litter bag technique during dry and wet seasons. Mass loss was the highest (49% and 57%) for A. heterophyllus and the lowest (25%) was found for L. chinensis. The highest initial rates (0.75% and 2.35%/day) of decomposition were observed for Z. jujuba and the lowest (0.50% and 0.79%/day) for L. chinensis. The highest decay constant was observed for A. heterophyllus (2.14 and 2.34) and the lowest (0.88 and 0.94) for L. chinensis. Leaf litter of all the studied species showed a similar pattern (K g N g P) of nutrient release during the decomposition process. Zizyphus jujuba showed comparatively higher return of N, P, and K than others. However, a significant () higher amount of mass loss, rate of decomposition, decay constant, and amount of nutrient return from leaf litter were observed during the wet season.
Stem Anatomy and Grafting Success of Chinese Chestnut Scions on 'AU-Cropper' and 'Qing' Seedling Rootstocks

Grafting failure of Chinese chestnut (Castanea mollissima Blume) trees is common. Some researchers have suggested that secondary phloem fibers in chestnut rootstock stems may interfere with graft union formation. Others suggest that high rootstock moisture content may reduce grafting success. This study was conducted to ascertain the precise arrangement of secondary phloem fibers in Chinese chestnut seedling rootstocks and to determine if they are associated with grafting failure. We also investigated the effects of moisture content of rootstocks and container growing medium on grafting success. Nodes on Chinese chestnut seedlings had 2/5 phyllotaxy with five alternate buds present in two revolutions around the stem. Vascular cambium in 1-year- old rootstock stems was arranged in a regular five-lobed cylinder in cross-sections. Primary phloem fibers were present in a discontinuous ring and secondary phloem fibers were usually clustered outside the cambium between the lobes. Grafts were successful when scion buds were placed on the rootstock disrupting secondary phloem fibers with cambia of the budded tissues aligned. Containerized rootstocks at 56% and 62% growing medium moisture content before grafting had 25% graft union success rates, whereas non-irrigated plants at 48% moisture had a 75% success rate.
Dynamics of a self-gravitating lightlike matter shell: A gauge-invariant Lagrangian and Hamiltonian description

A complete Lagrangian and Hamiltonian description of the theory of self-gravitating lightlike matter shells is given in terms of gauge-independent geometric quantities. For this purpose the notion of an extrinsic curvature for a null-like hypersurface is discussed and the corresponding Gauss-Codazzi equations are proved. These equations imply Bianchi identities for spacetimes with null-like, singular curvature. The energymomentum tensor density of a lightlike matter shell is unambiguously defined in terms of an invariant matter Lagrangian density. The Noether identity and Belinfante-Rosenfeld theorem for such a tensor density are proved. Finally, the Hamiltonian dynamics of the interacting ‘‘gravity1matter’’ system is derived from the total Lagrangian, the latter being an invariant scalar density.
Mechanical stress regulates gene expression via Rho/Rho-kinase signaling pathway

Exercise improves the performance of the cardiovascular system, striated muscle, and bones, and reduces obesity. Exercise provides for mechanical forces, which include fluid flow and stretching. These mechanical stimuli alter gene expression, which induces the physiological and pathological response in the organs and cells. However, the molecular mechanism underlying the conversion of mechanical stress into gene expression remains largely unknown. Recently, it has been reported that the mechanical stimuli alter the localization of the transcriptional co-activators MRTF (myocardin-related transcription factor) and YAP (Yes-associated protein)/TAZ (transcriptional co-activator with PDZ-binding motif) through actin remodeling. Since MRTF and YAP/TAZ are retained in the cytoplasm in a monomeric G (globular)-actindependent manner, actin polymerization promotes the translocation of MRTF and YAP/TAZ to the nucleus, and regulates the expression of several genes. The Rho family small GTPase member Rho and its effector, Rho-kinase (Rho-associated kinase), are critical regulators of actin remodeling. Rho/Rho-kinase suppresses the severing of actin through LIMK (LIM-kinase) and cofilin phosphorylation, thus enhancing actin polymerization. Mechanical stimuli induce actin polymerization through the Rho/Rho-kinase-LIMK-cofilin pathway. The Rho/Rho-kinase signaling pathway regulates gene expression and cell lineage by controlling the actin-dependent localization of MRTF and YAP/TAZ in response to mechanical stress. In this review, we focus on the molecular mechanism by which Rho/Rho-kinase controls gene expression in response to mechanical stimuli.
Hypermutation as an Evolutionary Mechanism for Achromobacter xylosoxidans in Cystic Fibrosis Lung Infection

Achromobacter xylosoxidans can cause chronic infections in the lungs of patients with cystic fibrosis (CF) by adapting to the specific environment. The study of longitudinal isolates allows to investigate its within-host evolution to unravel the adaptive mechanisms contributing to successful colonization. In this study, four clinical isolates longitudinally collected from two chronically infected patients underwent whole genome sequencing, de novo assembly and sequence analysis. Phenotypic assays were also performed. The isolates coming from one of the patients (patient A) presented a greater number of genetic variants, diverse integrative and conjugative elements, and different protease secretion. In the first of these isolates (strain A1), we also found a large deletion in the mutS gene, involved in DNA mismatch repair (MMR). In contrast, isolates from patient B showed a lower number of variants, only one integrative and mobilizable element, no phenotypic changes, and no mutations in the MMR system. These results suggest that in the two patients the establishment of a chronic infection was mediated by different adaptive mechanisms. While the strains isolated from patient B showed a longitudinal microevolution, strain A1 can be clearly classified as a hypermutator, confirming the occurrence and importance of this adaptive mechanism in A. xylosoxidans infection.
Which tests not witch hunts: a diagnostic approach for conducting replication research

Abstract Replication research can be used to explore original study results that researchers consider questionable, but it should also be a tool for reinforcing the credibility of results that are important to policies and programs. The challenge is to design a replication plan open to both supporting the original findings and uncovering potential problems. The purpose of this paper is to provide replication researchers with an objective list of checks or tests to consider when planning a replication study. The authors present tips for diagnostic replication exercises in four groups: validity of assumptions, data transformations, estimation methods, and heterogeneous impacts. For each group, the authors present an introduction to the issues, a list of replication tests and checks, some examples of how these checks are employed in replication studies of development impact evaluations, and a set of resources that provide statistical and econometric details. The authors also provide a list of don’ts for how to conduct and report replication research.
Water Erosion in a Long-Term Soil Management Experiment with a Humic Cambisol

ABSTRACT Water erosion, the main factor in soil degradation, is strongly influenced by soil cover and management. The objective of this study was to determine soil and water losses under natural rainfall conditions from 1993 to 2012 in the southern Santa Catarina Plateau, Brazil, in 3.5 × 22.1 m plots with crops in rotation to study the following management treatments: conventional tillage (CT), minimum tillage (MT), and no-tillage (NT), and a treatment with bare soil (BS). The soil cover remaining [. ]
Water Response of Upland Rice Varieties Adopted in Sub-Saharan Africa: A Water Application Experiment

Whether a rice Green Revolution in sub-Saharan Africa becomes a reality critically hinges on how far productive upland rice cultivation diffuses in the region. In order to quantify the drought tolerance, the rate of water response and the contribution of yield components to changes in yield due to water availability of upland rice varieties used in sub-Saharan Africa, we conducted water application experiments in Namulonge, Uganda, using NERICA 4, NERICA 10, NARIC 2 and Yumenohatamochi, with five different levels of water application. We found that the NERICA varieties were most drought tolerant, followed by NARIC 2. Yumenohatamochi did not withstand the lowest amount of water application of 378 mm. The results suggested that the minimum water requirement was around 311-400 mm per season for the three varieties used widely in East Africa, and around 420-600 mm for Yumenohatamochi, an upland variety in Japan famous in its drought tolerance. It was estimated that an additional water application of 1 mm increased rice yield by 11-12 kg /ha for the upland varieties tested. The high water response of upland rice was brought about by high water response of four yield components, among which the rate of grain filling contributed most to the increase in yield, followed by number of panicles/m2, number of grains per panicle and 1000- grain weight, in the order of the degree of contribution, for all the varieties tested.
Impact of Grape Products on Lipid Profile: A Meta-Analysis of Randomized Controlled Studies

Background: Growing evidence shows that grape polyphenols can improve cardiovascular risk factors. Although there are clear data supporting a beneficial effect of grape supplementation on blood pressure and glucose metabolism, the effects of grape polyphenols on lipid metabolism are still controversial. Objective: We performed a meta-analysis of randomized controlled trials (RCTs) to assess the effect of grape products on lipid profile. Design: A systematic search was performed in the PubMed, Web of Science, Scopus, and EMBASE databases without any language or publication year restriction. The reference lists of all retrieved articles were manually reviewed. RCTs evaluating the impact of grape products/juice/extracts on lipid profile were included. Difference in total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), oxidized low-density lipoprotein cholesterol (oxLDL-C), apolipoprotein (apo) A, apo B before and after administration of grape products or placebo were expressed as mean differences (MD) with pertinent 95% confidence intervals (95% CI). The impact of clinical and demographic features on effect size was assessed by meta-regression. Results: The administration of grape products is associated with a significant improvement of lipid profile, as evidenced by changes in TC (MD: −7.6 mg/dL (−0.2 mmol/L); 95% CI: −10.8, −4.4; p < 0.001), HDL-C (MD: 1.4 mg/dL (0.04 mmol/L); 95% CI: 0.8, 1.9; p < 0.001, I2 = 74.7%, p < 0.001), LDL-C (−6.3 mg/dL (−0.16 mmol/L); 95% CI: −9.5, −3.0; p < 0.001), oxLDL-C (MD: −4.5 U/L; 95% CI: −7.5, −1.5; p = 0.003, I2 = 90.6%, p < 0.001), apo B (MD: −2.4 mg/dL (−0.05 µmol/L); 95% CI: −4.5, −0.3; p = 0.026), and TG (MD: −14.5 mg/dL (−0.16 mmol/L); 95% CI: −17.7, −11.2; p < 0.001) levels in subjects receiving grape products compared to placebo. With regard to the extent of the lipid-lowering effect, compared to baseline values, the highest reduction was reported for LDL-C (MD: −5.6 mg/dL (−0.14 mmol/L); 95% CI: −9.5, −1.7; p = 0.005) and for oxLDL-C (MD: −5.0 U/L; 95% CI: −8.8, −1.2; p = 0.010, I2 = 0%, p = 0.470). Conclusions: Grape polyphenols exert a favorable effect on lipid profile in humans by significantly reducing plasma levels of LDL-C and oxLDL-C.

Cloud-top temperatures decrease significantly with increasing aerosol index (AI) over oceans and aerosol optical depth (AOT) over land for mixed-phase clouds with warm cloud bases; no significant changes were found for 10
THE DYNAMIC RELATIONSHIP BETWEEN MANAGERIAL OWNERSHIP AND FIRM’S PERFORMANCE IN VIETNAM

OWNERSHIP AND FIRM’S PERFORMANCE IN VIETNAM. An Thi Thanh Nguyen , Position: Lecturer at Faculty of Finance-Banking and Business Administration, Quy Nhon University, Vietnam. , Address: 170 An Duong Vuong, Quy Nhon, Binh Dinh, Vietnam, 590000 , Email: nguyenthithanhan@qnu.edu. vn, Phone: +84 904362509 Abstract Corporate governance is generally considered as a key factor for the operational success for enterprises. One of the most frequently discussed concepts among corporate governance factors is the ownership structure, particularly, managerial ownership. Various empirical studies have been conducted to examine the impact of diverse ownership structure aspects on firm’s performance. A better measurement of managerial ownership includes direct ownership and indirect is employed. To deal with endogeneity issue of managerial ownership, this paper focuses on the effect of the change in managerial ownership on the change in firm’s performance instead. The result indicates that the actual managerial ownership level probably did not move toward the optimal (estimated) level due to the existence of adjustment costs. Furthermore, reduction managerial ownership level goes together with the growth of firms which has not impacted on return on total assets, but it provides the positive impact on firm’s performance regarding market evaluation.

Title Fast Failure Detection of OpenFlow Channels

We propose a mechanism to detect OpenFlow channel failures quickly in switches and controllers where multiple controllers are running. In OpenFlow networks, it is important to maintain OpenFlow channels between controllers and switches are up and to detect channel failures immediately, so that messages to notify events such as port down and modification of flow tables are always delivered to the other side surely and quickly. Exchanging keep-alive messages frequently is undesirable for controllers because the controllers should handle many keep-alive messages from switches. This would be a significant overhead when the rate of other messages than keep-alive ones is low, because the controllers are forced to handle many keep-alive messages although such keep-alive messages do not affect network control directly. Our proposed mechanism adaptively sends keep-alive messages to detect quickly that a message is not reached to the other side, instead of checking whether a channel is up. A controller shares a message received from a switch with other controllers in a timely manner, and the controller regards a channel has been unavailable if the message notified by other controllers has not arrived via the channel. A switch sends keep-alive messages to all channels just after sending an important asynchronous message such as a port status message, and regards all channels have been gone down if the switch does not receive any response. The evaluation shows that our proposed mechanism reduces failure detection delay to timeout until receiving a response, and that overhead on latency is negligible.
Carcinus maenas Linnaeus , 1758 ( Crustacea : Decapoda : Brachyura )

Previous research has identified extensive inter-population variability in the morphology of the shore crab (Carcinus maenas L.). To determine the source of this variation (genetic or environmental), morphological and genetic data were analysed from crabs collected from eight sites around the coast of the UK. Ten morphometric traits were measured from over 800 crabs and the degree of morphological similarity among sites calculated using multivariate techniques. Allozyme electrophoresis was used to investigate patterns of genetic similarity. Extensive morphological variability was detected; eight out of the ten morphometric traits analysed were useful when discriminating between crabs from each site. Discriminant function analysis revealed that over 35% of individuals could be classified to their site of origin on the basis of their morphology. In contrast, the allozyme analysis revealed low levels of genetic variability, both within the meta-population and among the crab population at each site. Pairwise comparisons revealed a moderate correlation between the degree of morphological and genetic similarity of crabs at each site, which suggests that the observed phenotypic variability has a genetic component. However, only around 20% of the phenotypic variability detected was associated with the patterns of genetic similarity. This means that patterns of morphological variability in this species are largely determined by the local environmental conditions: local factors could have a within-generation selective influence on mean trait values or C. maenas may exhibit phenotypic plasticity.
Comparative Effects of Single Agent Rectal Diclofenac versus its Combination with Intramuscular Pentazocine on Post Caesarean Section Pain Relief in a Tertiary Institution in Southern Nigeria

Caesarean section (C/S) is one of the most common surgeries done globally in obstetrics. This operation commonly induces severe pain, hence reducing the pain after C/S is very important. The International Association for the Study of Pain (IASP) has noted that uncontrolled acute pain not only leads to discomfort and suffering, but can also have unwanted consequences, such as delayed wound healing, increased risk of morbidity, prolonged hospital stay, and the risk of developing chronic persistent pain [1]. In fact, in any post-caesarean section patient, early ambulation, breastfeeding and maternal bonding with the infant may be interfered by poor pain management [2].
