Authors: Springer Shmuel , Gottlieb Uri , Moran Uria , Verhovsky Guy , Yanovich Ran 
Published: June 2015

AbstractBackgroundChronic ankle instability (CAI) is attributed to functional instability driven by insufficient proprioception. However, it is not clear whether the deficits are related to global impaired performance or to specific decrease in ankle motor‐control. The aim of this study was to assess the correlation between lower limb postural control and upper limb position sense among people with CAI, in order to further explore the function of the central neural control in people with CAI.MethodsFourteen participants (10 males, 4 females) with self‐reported CAI and 14 age‐ and gender‐matched, healthy controls participated in this study. Each participant completed single‐limb stance postural control tests and shoulder position sense tests. The Overall Stability Index (OSI) was used as a measure of postural stability. The average of the absolute error score (AES) was calculated as a measure of shoulder position sense. Pearson correlations between the scores of the four body sites –lower limb postural stability (preferred/non‐preferred), shoulder (preferred/non‐preferred) were determined separately for each group.ResultsIn the control group, significant correlations were found between the OSI score of the right and left ankles (r = 0.887, p < 0.001), between the AES of the right and left shoulders (r = 0.656, p = 0.011), as well as between the OSI score and the AES of the non‐preferred side (r = 0.649, p = 0.012). In the CAI group, significant correlation was found only between the OSI score at both ankles (r = 0.6, p = 0.002).ConclusionsIndividuals with CAI demonstrated lower limb postural control and upper limb position sense similar to those shown in healthy controls. However, correlations between the lower and upper limbs were observed only in the healthy controls. Clinicians can use this information and employ activities that focus on coordinating the upper and lower extremities when designing neuromuscular control training programs for people with CAI.

Abstract
Background
The human gut microbiome is associated with the development of colon cancer, and recent studies have found changes in the microbiome in cancer patients compared to healthy controls. Studying the microbial communities in the tumor microenvironment may shed light on the role of host–bacteria interactions in colorectal cancer. Here, we highlight the major shifts in the colorectal tumor microbiome relative to that of matched normal colon tissue from the same individual, allowing us to survey the microbial communities in the tumor microenvironment and providing intrinsic control for environmental and host genetic effects on the microbiome.

Methods
We sequenced the microbiome in 44 primary tumor and 44 patient-matched normal colon tissue samples to determine differentially abundant microbial taxa These data were also used to functionally characterize the microbiome of the cancer and normal sample pairs and identify functional pathways enriched in the tumor-associated microbiota.

Results
We find that tumors harbor distinct microbial communities compared to nearby healthy tissue. Our results show increased microbial diversity in the tumor microenvironment, with changes in the abundances of commensal and pathogenic bacterial taxa, including Fusobacterium and Providencia. While Fusobacterium has previously been implicated in colorectal cancer, Providencia is a novel tumor-associated agent which has not been identified in previous studies. Additionally, we identified a clear, significant enrichment of predicted virulence-associated genes in the colorectal cancer microenvironment, likely dependent upon the genomes of Fusobacterium and Providencia.

Conclusions
This work identifies bacterial taxa significantly correlated with colorectal cancer, including a novel finding of an elevated abundance of Providencia in the tumor microenvironment. We also describe the predicted metabolic pathways and enzymes differentially present in the tumor-associated microbiome, and show an enrichment of virulence-associated bacterial genes in the tumor microenvironment. This predicted virulence enrichment supports the hypothesis that the microbiome plays an active role in colorectal cancer development and/or progression. Our results provide a starting point for future prognostic and therapeutic research with the potential to improve patient outcomes.
An isolated duodenal perforation in pediatric blunt abdominal trauma: a rare but distinct possibility
Authors: Dhua Anjan Kumar , Joshi Manoj 
Published: June 2015

AbstractIsolated duodenal perforation (IDP) in pediatric trauma is rarely reported. Since most of the children with blunt trauma are managed expectantly, timely diagnosis is imperative to avoid morbidity and mortality. We report a case of IDP and emphasize on certain specific clinical features indicating possibility of duodenal injury. We also stress upon the role of early contrast-enhanced computerized tomography (CECT) in such cases.

Abstract
We synthesized alkyl-substituted phenyl chrysenes as novel solution-processable transistor materials for single crystal organic transistors. All devices displayed typical p-channel characteristics, with the best field-effect mobility of 11.9 cm2 V−1 s−1 belonging to the m-7P-28CR based transistor.
Studies on Diastereoselective Functionalization, Optical Resolution, and Racemization Behaviors of Macrocyclic Bisimidazole of Winding-Vine-Shaped Molecular Asymmetry
Authors: Okayama Yoichi , Maruhashi Kazuki , Tsuji Satoru , Mori Atsunori 
Published: June 2015

Abstract
Macrocyclic alkene containing bisimidazole showing molecular asymmetry, which is synthesized by ring-closing metathesis, is subjected to several functional group transformation reactions of the olefin moiety. Syn-addition reactions such as epoxidation, dihydroxylation, and hydrogenation are found to proceed whereas anti-addition does not proceed. Optical resolution of racemic bisimidazole is successfully achieved with a preparative chiral column. Racemization behaviors of bisimidazole derivatives are also studied under several conditions.

Plutarch's Alexander the Great as Focus for Greek Identity. The Case of Alexander's Childhood and Youth in Vira Alexandri
The present paper concentrates on the character of Plutarch’s Alexander and his idealized Greek traits as visible in one particular set of Plutarch’s stories: the narratives on the childhood and youth of Alexander, presented in Vita Alexandri. By presenting him as a Greek hero, with a number of typically heroic and typically Hellenic features, Plutarch transforms the image of the Macedonian king, creating a model for his audience to identify as an embodiment of Greek greatness. While the portrait of Alexander in Plutarch’s Life of Alexander is rather nuanced and not entirely positive (see, for example, his behaviour in the East), Plutarch seems, in the stories of Alexander’s childhood, to be carefully presenting him as a perfect Greek model of a hero and a future leader.
Propagation of Financial Shocks: The Case of Venture Capital
Authors: Townsend Richard R. 
Published: June 2015

This paper investigates how venture-backed companies are affected when others sharing the same investor suffer a negative shock. In theory, companies may be helped or hurt in this scenario. To examine the topic empirically, I estimate the impact of the collapse of the technology bubble on non-information-technology (non-IT) companies that were held alongside IInternet companies in venture portfolios. Using a difference-in-differences framework, I find that the end of the bubble was associated with a significantly larger decline in the probability of raising continuation financing for these non-IT companies in comparison to others. This does not appear to be driven by unobservable company characteristics such as company quality or IT relatedness; for the same portfolio company receiving capital from multiple venture firms, investors with greater Internet exposure were significantly less likely to continue to participate in follow-on rounds. This paper was accepted by Itay Goldstein, operations management.
On linear degenerate elliptic PDE systems with constant coefficients
Authors: Katzourakis Nikos 
Published: June 2015

AbstractLet ${\mathbf{A}}$ be a symmetric convex quadratic form on ${\mathbb{R}^{Nn}}$ and Ω $\subset$$\mathbb{R}^{n}$ a bounded convex domain. We consider the problem of existence of solutions u: Ω $\subset$$\mathbb{R}^{n}$$\to$$\mathbb{R}^{N}$ to the problem${}\left\{\begin{aligned} \displaystyle\sum_{\beta=1}^{N}\sum_{i,j=1}^{n}%
\mathbf{A}_{\alpha i\beta j}D^{2}_{ij}u_{\beta}&\displaystyle=f_{\alpha}&&%
\displaystyle\text{in }\Omega,\\
\displaystyle u&\displaystyle=0&&\displaystyle\text{on }\partial\Omega,\end{%
aligned}\right.\phantom{\}}$when ${f\in L^{2}(\Omega,\mathbb{R}^{N})}$. Problem (1) is degenerate elliptic and it has not been considered before without the assumption of strict rank-one convexity. In general, it may not have even distributional solutions. By introducing an extension of distributions adapted to (1), we prove existence, partial regularity and by imposing an extra condition uniqueness as well. The satisfaction of the boundary condition is also an issue due to the low regularity of the solution. The motivation to study (1) and the method of the proof arose from recent work of the author

Modelling of non-linear losses in an integrated contactless power supply for magnetically levitated elevator systems using discrete circuit elements

Published: June 2015

Abstract
A contactless energy transmission system is essential to supply onboard systems of electromagnetically levitated vehicles without physical contact to the guide rail. One of the possibilities to realise a contactless power supply (CPS) is by integrating the primary actuator into the guide rail of an electromagnetic guiding system (MGS). The secondary actuator is mounted on the elevator car. During the energy transmission, load dependent non-linear losses occur in the guide rail. The additional losses, which are caused by the leakage flux penetrating into the guide rail, cannot be modelled using the classical approach of iron losses in the equivalent circuit of a transformer, which is a constant parallel resistance to the mutual inductance. This paper introduces an approach for modelling the load dependent non-linear losses occurring in the guide rail using additional variable discrete circuit elements
Field-circuit modelling of an advanced welding transformer with two parallel rectifiers
Authors: Sakhno Lyudmila , Sakhno Olga , Dubitsky Simon 
Published: June 2015

Abstract
The new topology of three-winding welding transformer is proposed. Each secondary winding is connected in parallel through the separate bridge rectifier to the welding arc. The main feature of the proposed device is parallel working of two secondary windings with different rated voltage. The advantage is nonlinear transformation ratio of current that provides unprecedented power efficiency. The self- and mutual leakage inductances, which are important in power conversion, are calculated by 2D FEA model. The operational current of the device is modelled numerically via P-Spice simulator. The proposed topology is up to 30% more power effective than conventional welding transformer provided that the leakage inductances of primary and secondary windings are correctly fitted. This transformer is used for manual arc welding

Authors: Morariu S.H. , Badea M.A. , Cotoi O.S. , Vartolomei M.D. , Badea Iudita-Maria , Suciu M. , Buicu F. 
Published: June 2015

Abstract
Introduction: Relapsing polychondritis has been described by Rudolph von Jaksch Warthenhorst in 1923 under the name of polichondropathy. Although the etiology is unknown, an autoimmune mechanism is likely due to formation of autoantibodies to type II collagen in the extracellular matrix of the cartilage with its consequent destruction.
Case report: We present a case with relapsing polychondritis according to McAdam and Damiani criteria and with positive Western blot reaction for Ac IgG anti Borrelia burgdorferi. Serological reaction became negative and the patient presented favorable evolution at 6 months follow-up after corticosteroid therapy and antibiotics.
Conclusion: Chronic infection with Borrelia burgdorferi may play a role in relapsing polychondritis determinism

Published: June 2015

Abstract
Objective: The aim of the study is to assess 24-hour blood pressure variability, circadian blood pressure profile and its relation to 24-hour blood pressure and cardiovascular risk factors in primary hypertension without any associated disease versus associated with a disease such as diabetes or chronic kidney disease. Methods: This observational study included 90 hypertensive patients, 49 with primary hypertension without associated disease and 41 patients with primary hypertension and diabetes or chronic kidney disease. Circadian blood pressure profile and 24-hour variability were assessed using ambulatory monitoring. Laboratory data regarding cardiovascular risk factors and demographic data were collected in a questionnaire. Results: The number of dipper patients was higher in the group without associated disease, but the difference was not statistically significant (p=0.27). In both groups a positive correlation was found between 24-hour systolic blood pressure variability and 24-hour systolic blood pressure (p=0.029) and was related to age (p=0.031). In the second group, systolic variability showed a positive correlation with serum triglycerides (p=0.006, r=0.416, CI: 0.1252 to 0.6422). Conclusion: Our findings suggest that systolic blood pressure variability is related to age, systolic blood pressure values and serum lipid levels. To prevent end organ damage in hypertension, the assessment of ambulatory monitoring derived 24-hour systolic blood pressure variability and its reduction may be at least as important as blood pressure lowering.
The CO2 Absorber Based on LiOH
Authors: Zilberman P. 
Published: June 2015

Abstract
Carbon dioxide absorbers have been used in anesthesiology for many years. However, this process is not limited to this field of medicine. Removing carbon dioxide from human environment is used in other areas as well: mining industry, submarines, scuba diving, space travel and many others. The rationale to remove carbon dioxide from confined spaces is that cannot be eliminated otherwise. Anesthesia practitioners are well aware of this component of the circle system, the carbon dioxide absorber. In daily practice the clinician is less concerned with what kind of substance fills the dedicated canister, as this is usually in the care of the maintenance personnel. The appearance of Sevoflurane and Desflurane, with their own chemical characteristics, prompted the clinician to dedicate new attention to these absorbents. The classical substances used for this purpose are different combinations of limes. The practical concern of the anesthesiologist is to notice when the absorbent is consumed and call for its replacement. Still, many other aspects remain: compound A formation with Sevoflurane, carbon monoxide formation with Desflurane and dry absorbent for instance. The latest member of these products in the medical field is the LiOH carbon dioxide absorbent. Although used for many years in the space exploration, its way into the operating room is a rather recent achievement. Special chemical properties and high absorptive capacity make this new type of absorbent an attractive option for modern anesthesia practice. The article below invites the reader through a short journey on the history of the CO2 absorbents and anesthesia circuits, Lithiumas a chemical element and, finally, to this new type of absorbent.
Effect of body size on the abundance of ectoparasitic mites on the wild rodent Oligoryzomys nigripes
Authors: Fernandes Fernanda Rodrigues , Cruz Leonardo Dominici , Linhares Arício Xavier , Zuben Claudio José Von 
Published: June 2015

AbstractThe abundance of parasites on a host can be affected by several factors; in this study, we investigated the influence of sex and body size of the host rodent Oligoryzomys nigripes on the abundance of ectoparasitic mites (Acari: Mesostigmata). The generalized linear model indicated that body size (indicative of age) of the host rodent O. nigripes significantly contributed to the variation in the abundance of mites on host rodents at the Experimental Station of Itirapina. This trend of increased parasitism on hosts with larger body sizes may be linked to the fact that larger individuals are able to support the coexistence of a larger number of parasites, and being more mobile, are more exposed to infection by parasites.
Molecular characterization of Fascioloides magna (Trematoda: Fasciolidae) from south-western Poland based on mitochondrial markers

Published: June 2015

AbstractThe giant liver fluke, Fascioloides magna, is a veterinary important liver parasite of free living and domestic ruminants. This originally North American parasite was introduced along with its cervid hosts to Europe where it has established three permanent natural foci - in northern Italy, central and southern parts of the Czech Republic and the Danube floodplain forests. The first record on fascioloidosis in Poland originated from the Lower Silesian Forest in south-western Poland and since then an occurrence of F. magna in this country has not been documented. Recently, the parasitological examination of red deer (Cervus elaphus elaphus) from the Lower Silesian Wilderness (south-western Poland) revealed the presence of F. magna eggs. In order to determine the genetic interrelationships of the Polish giant liver fluke individuals, they were molecularly analyzed by mitochondrial cytochrome c oxidase subunit I (cox1) and nicotinamide dehydrogenase subunit I (nad1) and compared with haplotypes of so far studied European populations of the parasite. The study revealed the genetic uniformity of F. magna specimens from Poland with part of individuals from the Czech natural focus.Note: Nucleotide sequence data reported in this paper are available in the GenBank

Published: June 2015

Abstract
Upper Cretaceous to Pleistocene volcanic rocks of the Bohemian Massif represent the easternmost part of the Central European Volcanic Province. These alkaline volcanic series include rare melilitic rocks occurring as dykes, sills, scoria cones and flows. They occur in three volcanic periods: (i) the Late Cretaceous to Paleocene period (80–59 Ma) in northern Bohemia including adjacent territories of Saxony and Lusatia, (ii) the Mid Eocene to Late Miocene (32.3–5.9 Ma) period disseminated in the Ohře Rift, the Cheb–Domažlice Graben, Vogtland, and Silesia and (iii) the Early to Late Pleistocene period (1.0–0.26 Ma) in western Bohemia. Melilitic magmas of the Eocene to Miocene and Pleistocene periods show a primitive mantle source [(143Nd/144Nd)t=0.51280–0.51287; (87Sr/86Sr)t=0.7034–0.7038)] while those of the Upper Cretaceous to Paleocene period display a broad scatter of Sr–Nd ratios. The (143Nd/144Nd)t ratios (0.51272–0.51282) of the Upper Cretaceous to Paleocene rocks suggest a partly heterogeneous mantle source, and their (87Sr/86Sr)t ratios (0.7033–0.7049) point to an additional late- to post-magmatic hydrothermal contribution. Major rock-forming minerals include forsterite, diopside, melilite, nepheline, sodalite group minerals, phlogopite, Cr- and Ti-bearing spinels. Crystallization pressures and temperatures of clinopyroxene vary widely between ~1 to 2 GPa and between 1000 to 1200 °C, respectively. Nepheline crystallized at about 500 to 770 °C. Geochemical and isotopic similarities of these rocks occurring from the Upper Cretaceous to Pleistocene suggest that they had similar mantle sources and similar processes of magma development by partial melting of a heterogeneous carbonatized mantle source.
The Entangled Sovereignties of Air Police: Mapping the Boundary of the International and the Imperial
Authors: Munro Campbell 
Published: June 2015

AbstractThe contemporary proliferation of drones and other forms of aerial interventions herald the (re)emergence of air policing as the principal modality for the fabrication of order in the global periphery. Air policing is predominantly framed by international legal analysis as merely ‘killing from above,’ yet this designation obfuscates the concomitant occupation of airspaces entailed by drones and other aerial technologies. Such occupations constitute an assertion of jurisdiction in nominally sovereign airspaces authorised by latent imperial legality. The history of air policing reveals a genealogy of ‘aerial imperial formations,’ enfolded within the abstract airspaces regulated by international law notions of ‘complete and exclusive’ sovereignty. Through a focus on the spatio-legal construction of airspace, this paper proposes a reframing of the nexus of sovereignty, jurisdiction and territory, and suggests that we conceive of the principle of indivisible sovereignty as propounded under

The Revolving Door and the Entrenchment of the Permanent War Economy
Authors: Duncan Thomas K. , Coyne Christopher J. 
Published: June 2015

AbstractThis paper analyzes the “revolving door” phenomena in the military sector in the US. The revolving door refers to the back-and-forth movement of personnel between the government and private sector. We examine the structure of the revolving door and explain how its very nature leads to the perpetuation of the permanent war economy. This analysis yields several important implications. First, the dynamics of the revolving door shape the military-industrial complex in a way that serves the narrow interests of select elites rather than the broad interests of citizens. Second, because the perverse incentives are a product of the institutional structure of the US military sector, the negative consequences are also structural and cannot be solved by increased oversight.
