Published: June 2017

Abstract
PMN-expressed fucosylated glycans from the Lewis glycan family, including Lewis-x (Lex) and sialyl Lewis-x (sLex), have previously been implicated in the regulation of important PMN functions, including selectin-mediated trafficking across vascular endothelium. Although glycans, such as Lex and sLex, which are based on the type 2 sequence (Galβ1-4GlcNAc-R), are abundant on PMNs, the presence of type 1 Galβ1-3GlcNAc-R glycans required for PMN expression of the closely related stereoisomer of Lex, termed Lewis-A (Lea), has not, to our knowledge, been reported. Here, we show that Lea is abundantly expressed by human PMNs and functionally regulates PMN migration. Using mAbs whose precise epitopes were determined using glycan array technology, Lea function was probed using Lea-selective mAbs and lectins, revealing increased PMN transmigration across model intestinal epithelia, which was independent of epithelial-expressed Lea. Analyses of glycan synthetic machinery in PMNs revealed expression of β1-3 galactosyltransferase and α1–4 fucosyltransferase, which are required for Lea synthesis. Specificity of functional effects observed after ligation of Lea was confirmed by failure of anti-Lea mAbs to enhance migration using PMNs from individuals deficient in α1–4 fucosylation. These results demonstrate that Lea is expressed on human PMNs, and its specific engagement enhances PMN migration responses. We propose that PMN Lea represents a new target for modulating inflammation and regulating intestinal, innate immunity.

Published: June 2017

Purpose Literature has documented the prevalence of anxiety and its adverse effect on quality of life among patients with breast cancer from Western countries, yet cross-cultural examinations with non-Western patients are rare. This cross-cultural study investigated differences in anxiety and its association with quality of life between US and Chinese patients with breast cancer. Methods Patients with breast cancer from the United States and China completed measures for anxiety (Spielberger State-Trait Anxiety Inventory) and quality of life (Functional Assessment of Cancer Therapy-Breast). Results After controlling for demographic and medical characteristics, Chinese patients reported higher levels of trait and state anxiety than US patients. Although there was an association between anxiety and quality of life in both groups of patients, the association between state anxiety and quality of life was stronger among Chinese patients than among US patients, with the association between trait anxiety and quality of life the same between the two cultural samples. Conclusion These findings suggest that anxiety and its association with quality of life among patients with breast cancer varies depending on cultural context, which reveals greater anxiety and poorer quality of life among Chinese patients compared with US patients. This suggests greater unmet psychosocial needs among Chinese patients and highlights the need to build comprehensive cancer care systems for a better quality of life in Chinese populations.
HIRA deficiency in muscle fibers causes hypertrophy and susceptibility to oxidative stress

Published: June 2017

ABSTRACT
Nucleosome assembly proceeds through DNA replication-coupled or replication-independent mechanisms. For skeletal myocytes, whose nuclei have permanently exited the cell cycle, replication-independent assembly is the only mode available for chromatin remodeling. For this reason, any nucleosome composition alterations accompanying transcriptional responses to physiological signals must occur through a DNA replication-independent pathway. HIRA is the histone chaperone primarily responsible for replication-independent incorporation of histone variant H3.3 across gene bodies and regulatory regions. Thus, HIRA would be expected to play an important role in epigenetically regulating myocyte gene expression. The objective of this study was to determine the consequence of eliminating HIRA from mouse skeletal myocytes. At 6 weeks of age, myofibers lacking HIRA showed no pathological abnormalities; however, genes involved in transcriptional regulation were downregulated. By 6 months of age, myofibers lacking HIRA exhibited hypertrophy, sarcolemmal perforation and oxidative damage. Genes involved in muscle growth and development were upregulated, but those associated with responses to cellular stresses were downregulated. These data suggest that elimination of HIRA produces a hypertrophic response in skeletal muscle and leaves myofibers susceptible to stress-induced degeneration.
Rac1 switching at the right time and location is essential for Fcγ receptor-mediated phagosome formation
Authors: Ikeda Yuka , Kawai Katsuhisa , Ikawa Akira , Kawamoto Kyoko , Egami Youhei , Araki Nobukazu 
Published: June 2017

ABSTRACT
Lamellipodia are sheet-like cell protrusions driven by actin polymerization mainly through Rac1, a GTPase molecular switch. In Fcγ receptor-mediated phagocytosis of IgG-opsonized erythrocytes (IgG-Es), Rac1 activation is required for lamellipodial extension along the surface of IgG-Es. However, the significance of Rac1 deactivation in phagosome formation is poorly understood. Our live-cell imaging and electron microscopy revealed that RAW264 macrophages expressing a constitutively active Rac1 mutant showed defects in phagocytic cup formation, while lamellipodia were formed around IgG-Es. Because activated Rac1 reduced the phosphorylation levels of myosin light chains, failure of the cup formation is probably due to inhibition of actin/myosin II contractility. Reversible photo-manipulation of the Rac1 switch in macrophages fed with IgG-Es could phenocopy two lamellipodial motilities: outward-extension and cup-constriction by Rac1 ON and OFF, respectively. In conjunction with fluorescence resonance energy transfer imaging of Rac1 activity, we provide a novel mechanistic model of phagosome formation spatiotemporally controlled by Rac1 switching within a phagocytic cup.
Tai Chi as a falls prevention strategy in older adults compared to conventional physiotherapy exercise: A review
Authors: Plummer Megan , Bradley Claire 
Published: June 2017

Background/Aims: Falls are an increasing problem in the elderly population. Several pieces of primary and secondary research have been carried out into the effectiveness of Tai Chi as a falls prevention intervention. Benefits such as improvements in balance, dual task working, and proprioception have been reported. Nevertheless, the research remains inconclusive. There is uncertainty regarding an optimum Tai Chi style, dosage, and patient characteristics for whom Tai Chi is most suitable. This review aims to explore and discuss the current best evidence to assess the efficacy of Tai Chi as a falls prevention strategy for adults aged 65 and over. Methods: A systematic literature search was carried out using CINAHL, MEDLINE and AMED, along with predetermined inclusion and exclusion criteria, eventually yielding four papers for the review. Narrative synthesis was then carried out to identify themes to answer the research aim. Some evidence showed that although Tai Chi is effective for reducing falls in the population aged 65 and over, the body of evidence did not conclude this effect to be significant. Conclusions: There is some evidence for positive intervention effects in the pre-frail subgroup of the population; however, more research is needed to confirm this. A multidimensional falls prevention programme may prove more beneficial for falls prevention in the elderly at present—although Tai Chi could indeed be an element of this.
Partners' experiences of caregiving and perceptions of inpatient rehabilitation following catastrophic injury
Authors: Aggar Christina , Pryor Julie , Fisher Murray 
Published: June 2017

Aim: The aim of this study is to critically review the research literature investigating the experiences of providing care to a spouse or partner during inpatient rehabilitation following a catastrophic injury (namely, stroke, traumatic brain injury or spinal cord injury) and their perceptions of inpatient rehabilitation service delivery. Method: An integrative review was undertaken to determine the extent to which the topic has been investigated. Quantitative and qualitative research papers were systematically identified in peer-reviewed journals in electronic databases. Findings: Five articles published between 1994 and 2016 reported on four studies investigating the experiences of caregiving specifically by a spouse/partner to a person receiving rehabilitation following a stroke. No research was found that committed to understanding the experiences of the spouse/partner and their perceptions of inpatient rehabilitation service delivery following traumatic brain injury and spinal cord injury exclusively. Conclusion: The diverse aspects of caregiving are not an area of inquiry in rehabilitation service delivery following a traumatic brain injury or spinal cord injury. Further research in this area is warranted.

Published: June 2017

Abstract
Using principles of community-based participatory research we developed a new theory-based measure of health-related quality of life (HRQOL) for individuals with intellectual disability (ID). We recruited adults with ID (n = 129) to take part in interviews and review successive versions of HRQOL items. Critical input about content and understandability shaped the items, as did input from four focus groups of parents/caregivers (n = 16) and representative stakeholders from community-based agencies (n = 7). The resulting HRQOL measure, called the HRQOL-IDD, contains 42 items. The response format depicts a gradient of fluid-filled cups (“none” to “full”) to represent frequency of experience of each item on a 5-point scale.

Study Of Solid Planar Source For Phosphorus Diffution Process On Semiconductor Devices Fabrication
Authors: Widodo S. 
Published: June 2017

The sourcing lifetimes, microstructural staility, and diffution performance of a new solid planar phosphorus source for silicon doping were investigated in the temperature range 900-1000 0C. The source wafers were highly porous ceramic wafers containing 25 weight percentage (w/o) SiP2O7 as the “active” component in an inert refractory binder matrix. The microstructural stability and thermografimetric analysis (TGA) result indicated the structural integrity and sourcing ability of this materials at temperatures of at least 1050 0C. Theoretical lifetimesof 260 and 3400 hr at 1000 and 900 0C, respectively, have been predicted from the TGA results. Experimental data relating sheet resistance, junction depth, and diffution coefficient for silicon wafers doped using these source wafers are presented. Special material handling procedure are also described. Keywords : diffution process, solid phosphorus source, SiP2O5, semiconductor devices
Harmonicity of vector fields on a class of Lorentzian solvable Lie groups
Authors: Tan Ju , Deng Shaoqiang 
Published: June 2017

Abstract
In this paper, we consider a special class of solvable Lie groups such that for any x, y in their Lie algebras, [x, y] is a linear combination of x and y. We investigate the harmonicity properties of invariant vector fields of this kind of Lorentzian Lie groups. It is shown that any invariant unit time-like vector field is spatially harmonic. Moreover, we determine all vector fields which are critical points of the energy functional restricted to the space of smooth vector fields.

Abstract
In this paper we study an extension of Yamabe solitons for inequalities. We show that a Riemannian complete non-compact shrinking Yamabe soliton (M, g, V, λ) has finite fundamental group, provided that the scalar curvature is strictly bounded above by λ. Furthermore, an instance of illustrating the sharpness of this inequality is given. We also mention that the fundamental group of the sphere bundle SM is finite.
Steiner’s Porism in finite Miquelian Möbius planes
Authors: Hungerbühler Norbert , Kusejko Katharina 
Published: June 2017

AbstractWe investigate Steiner’s Porism in finite Miquelian Möbius planes constructed over the pair of finite fields GF(q) and GF(q2), for an odd prime powerq. Properties of common tangent circles for two given concentric circles are discussed and with that, a finite version of Steiner’s Porism for concentric circles is stated and proved. We formulate conditions on the length of a Steiner chain by using the quadratic residue theorem in GF(q). These results are then generalized to an arbitrary pair of non-intersecting circles by introducing the notion of capacitance, which turns out to be invariant under Möbius transformations. Finally, the results are compared with the situation in the classical Euclidean plane.

Published: June 2017

AbstractSynchronization in the energy generated by renewable energy sources is one of the significant issue associated with the converter used in the system module. The presented paper concentrates on the design aspect of a PV and wind power input to a DC-DC converter which can be practically useful in hybrid renewable energy power systems. In this regard, the proposed converter can be utilized to obtain a smooth regulated output voltage from the given input renewable energy power sources. The proposed converter can be efficiently work under critical conditions having very few ripple in current waveform of input or output. A major advantage with this type of converter is the simple circuit with respect to the conventional converters in some critical situations. At the end, the result based on the simulation exercise and various experiments, performance of the converter in different situations is presented so that the efficiency of the designed converter arrangement is accepted.
Influence of the mechanical fatigue progress on the magnetic properties of electrical steel sheets

Published: June 2017

AbstractThe purpose of this paper is to study the variation of the magnetic properties of non-oriented electrical steel sheets with the fatigue state during cyclic mechanical loading. The obtained results are central to the design of variable drives such as traction drives in electric vehicles in which varying mechanical loads, e.g. in the rotor core (centrifugal forces), alter the magnetic properties. Specimens of non-oriented electrical steel are subject to a cyclically varying mechanical tensile stress with different stress amplitudes and number of cycles. The specimens are characterised magnetically at different fatigue states for different magnetic flux densities and magnetising frequencies. The measurements show a variation in magnetic properties depending on the number of cycles and stress magnitude which can be explained by changes in the material structure due to a beginning mechanical fatigue process. The studied effect is critical for the estimation of the impact of mechanical material fatigue on the operational behaviour of electrical machines. Particularly in electrical machines with a higher speed where the rotor is stressed by high centrifugal forces, material fatigue occurs and can lead to deterioration of the rotor’s stack lamination.

Published: June 2017

AbstractThis article deals with magnetic nano-fluids, which are the part of transformer oil ITO 100 and their behavior is influenced by a permanent magnetic field. We performed an IRC analysis in the time domain on the three different samples. Measurements were made before and after radiation of an electromagnetic field. The main objective was to examine changes in the properties of the samples due to the influence of the electromagnetic field. The measurements depend on the orientation of the external magnetic field. This behavior occurs especially during the structuring of the nanoparticles in the sample exposed to the magnetic field. These processes change the polarization of the liquid because the nanoparticles concentration is contained in the fluid.
A modelling of AC voltage stabilizer based on a hybrid transformer with matrix converter
Authors: Szcześniak Paweł 
Published: June 2017

AbstractThis article presents a study of an AC voltage stabilizer based on a three-phase hybrid transformer combined with a matrix converter. The proposed solution is used to control AC voltage amplitude and phase shift. By adjustment of these voltage parameters we can reduce the effects of overvoltage, voltage dips or lamp flicker. Such negative phenomena are very significant, particularly from the perspective of the final consumer and sensitive loads connected to the power network. Often the voltage in the power system can be adjusted using a mechanical or thyristor controlled regulator, which in a stepwise manner switches the taps of the electromagnetic transformer. The method for obtaining continuous control of the voltage magnitude and phase shift with the use of a conventional transformer with two output windings and a matrix converter is presented in this paper. The operating principles, mathematical model and properties of the proposed voltage stabilizers are discussed in this paper. The main part of the article will be devoted to the mathematical model which is based on an averaged equation. Computer simulation results are presented and compared with the results of a mathematical study.
Profit of Tourism Companies and their Market Evaluation On ZSE
Authors: Penda Ivor Altaras 
Published: June 2017

Abstract
The author of this paper presents a statistical analysis of data on realized profits of companies in the tourist sector, whose shares are listed on the Zagreb Stock Exchange and used for active trading. Data on the realized profit for the companies in accounting period 2010 - 2015 is correlated with the prices of shares. Based on the above obtained results about the direction and strength of this correlation the author concludes about the extent to which the market takes into account profit of the companies as a relevant indicator for investments. This information can be extremely significant because, on the one hand, it provides information about the functionality of the market as a comprehensive socio-economic mechanism that anticipates all the available information based on which the prices of the shares are created as a monetary expression of the presumed value of companies. On the other hand, this information tells us about the expectations of active market participants about the future development of the tourism sector, which already accounts for almost 20% of the Croatian GDP. In addition, the author examines what other explanations could be used for the part of variance which is not explained with the correlation between profit and price of shares.

Published: June 2017

Abstract
Foreign direct investments include equity capital, reinvested earnings and debt relations between ownership-related residents and non-residents. Since 31 October 2014, the Croatian National Bank has started to publish information in the field of statistics Relations (balance of payments, foreign debt and the IIP) in accordance with the methodology prescribed by the sixth edition of the Manual on Balance of Payments (Eng. Balance of Payments and International Investment Position Manual, BPM6), thus changing the presentational form of direct investment. Direct investments are not classified according to the so-called direction of investments (Eng. directional principle) on direct investment in Croatia and direct investment abroad anymore, but according to BPM6 apply the socalled principle of assets and liabilities (Eng. Assets / Liabilities principle). The aim is to point out the differences between the standards BPM5 and BPM6 and determine which activities and which countries are the most represented in the structure of direct investments in Croatia. By identifying relevant activities and countries in the structure of foreign direct investment, relevant information is obtained about the macroeconomic state of the Republic of Croatia and about the opportunities and potential dangers that certain activities and countries provide.

Published: June 2017

AbstractThis paper presents the results of computer simulations carried out to determine coordination numbers for a system of parallel cylindrical fibres distributed at random in a circular matrix according to twodimensional pattern created by random sequential addition scheme. Two different methods to calculate coordination number were utilized and compared. The first method was based on integration of pair distribution function. The second method was the modified sequential analysis. The calculations following from ensemble average approach revealed that these two methods give very close results for the same neighbourhood area irrespective of the wide range of radii used for calculation.
