Classical Magnetism and an Integral Formula Involving Modified Bessel Functions
Authors: Ciftja Orion 
Published: April 2018

AbstractWe study an integral expression that is encountered in some classical spin models of magnetism. The idea is to calculate the key integral that represents the building block for the expression of the partition function of these models. The general calculation allows one to have a better look at the internal structure of the quantity of interest which, in turn, may lead to potentially new useful insights. We find out that application of two different approaches to solve the problem in a general-case scenario leads to an interesting integral formula involving modified Bessel functions of the first kind which appears to be new. We performed Monte Carlo simulations to verify the correctness of the integral formula obtained. Additional numerical integration tests lead to the same result as well. The approach under consideration, when generalized, leads to a linear integral equation that might be of interest to numerical studies of classical spin models of magnetism that rely on the well-established transfer-matrix formalism.
Exact analytical modeling of magnetic vector potential in surface inset permanent magnet DC machines considering magnet segmentation
Authors: Jabbari Ali 
Published: April 2018

Abstract
Surface inset permanent magnet DC machine can be used as an alternative in automation systems due to their high efficiency and robustness. Magnet segmentation is a common technique in order to mitigate pulsating torque components in permanent magnet machines. An accurate computation of air-gap magnetic field distribution is necessary in order to calculate machine performance. An exact analytical method for magnetic vector potential calculation in surface inset permanent magnet machines considering magnet segmentation has been proposed in this paper. The analytical method is based on the resolution of Laplace and Poisson equations as well as Maxwell equation in polar coordinate by using sub-domain method. One of the main contributions of the paper is to derive an expression for the magnetic vector potential in the segmented PM region by using hyperbolic functions. The developed method is applied on the performance computation of two prototype surface inset magnet segmented motors with open circuit and on load conditions. The results of these models are validated through FEM method.

AbstractSynthetic biology builds upon the techniques and successes of genetics, molecular biology, and metabolic engineering by applying engineering principles to the design of biological systems. The field still faces substantial challenges, including long development times, high rates of failure, and poor reproducibility. One method to ameliorate these problems would be to improve the exchange of information about designed systems between laboratories. The synthetic biology open language (SBOL) has been developed as a standard to support the specification and exchange of biological design information in synthetic biology, filling a need not satisfied by other pre-existing standards. This document details version 2.2.0 of SBOL that builds upon version 2.1.0 published in last year’s JIB special issue. In particular, SBOL 2.2.0 includes improved description and validation rules for genetic design provenance, an extension to support combinatorial genetic designs, a new class to add non-SBOL data as attachments, a new class for genetic design implementations, and a description of a methodology to describe the entire design-build-test-learn cycle within the SBOL data model.

Authors: Ilhan Nevin , Susam Solmaz , Parlak Ak Tuba , Gul Baykalir Burcu 
Published: April 2018

AbstractBackground:Sepsis is characterized dysregulated inflammatory response and is the leading cause of organ failure or injury and death in critical care units.Ginkgo bilobaextract 761 (EGb 761) is characterized by antioxidant activity. There is no clear data in the functional role of EGb 761 that inhibiting of proinflammatory cytokines exist in sepsis. The purpose of this study was to investigate the antiinflammatory effect of EGb 761 on the levels of vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) and inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS) induced rat sepsis model.Methods:The animals were randomly divided into the following six groups: the control, LPS, flunixin meglumine (FM), EGb 761, LPS+FM and LPS+EGb 761 groups. Enzyme-linked immunosorbent assay (ELISA) analysis was applied to measure serum levels of VEGF, MMP-9, and iNOS.Results:Serum iNOs (p<0.05), VEGF (p<0.01) and MMP-9 (p<0.05) levels were significantly higher in the sepsis group. Treatment with EGb 761 decreased serum iNOs levels (p<0.01), VEGF and MMP-9 levels decreased significantly (p<0.05). Also, treatment with FM decreased iNOs (p<0.01), VEGF and MMP-9 levels significantly (p<0.05).Conclusions:It is suggested that sepsis may lead to increase serum iNOs, MMP-9, and VEGF levels and treatment of EGb 761 may have a potential antiinflammatory effect against LPS-induced sepsis.
A Geršgorin-type eigenvalue localization set with n parameters for stochastic matrices
Authors: Wang Xiaoxiao , Li Chaoqian , Li Yaotang 
Published: April 2018

Abstract
A set in the complex plane which involves n parameters in [0, 1] is given to localize all eigenvalues different from 1 for stochastic matrices. As an application of this set, an upper bound for the moduli of the subdominant eigenvalues of a stochastic matrix is obtained. Lastly, we fix n parameters in [0, 1] to give a new set including all eigenvalues different from 1, which is tighter than those provided by Shen et al. (Linear Algebra Appl. 447 (2014) 74-87) and Li et al. (Linear and Multilinear Algebra 63(11) (2015) 2159-2170) for estimating the moduli of subdominant eigenvalues.
Lifting components in clean abelian ℓ-groups
Authors: Boulabiar Karim , Smiti Samir 
Published: April 2018

Abstract
Let G be an abelian ℓ-group with a strong order unit u > 0. We call G
u-clean after Hager, Kimber, and McGovern if every element of G can be written as a sum of a strong order unit of G and a u-component of G. We prove that G is u-clean if and only if u-components of G can be lifted modulo any ℓ-ideal of G. Moreover, we introduce a notion of u-suitable ℓ-groups (as a natural analogue of the corresponding notion in Ring Theory) and we prove that the ℓ-group G is u-clean when and only when it is u-suitable. Also, we show that if E is a vector lattice, then E is u-clean if and only if the space of all u-step functions of E is u-uniformly dense in E. As applications, we will generalize a result by Banaschewski on maximal ℓ-ideals of an archimedean bounded f-algebras to the non-archimedean case. We also extend a result by Miers on polynomially ideal C(X)-type algebras to the more general setting of bounded f-algebras.
Groups with positive rank gradient and their actions
Authors: Shusterman Mark 
Published: April 2018

Abstract
We show that given a finitely generated LERF group G with positive rank gradient, and finitely generated subgroups A, B ≤ G of infinite index, one can find a finite index subgroup B
0 of B such that [G : 〈A ∪ B
0〉] = ∞. This generalizes a theorem of Olshanskii on free groups. We conclude that a finite product of finitely generated subgroups of infinite index does not cover G. We construct a transitive virtually faithful action of G such that the orbits of finitely generated subgroups of infinite index are finite. Some of the results extend to profinite groups with positive rank gradient.

Authors: Korzeniewska Ewa , Szczesny Artur , Krawczyk Andrzej , Murawski Piotr , Mróz Józef , Seme Sebastian 
Published: April 2018

AbstractIn this paper, the authors describe the distribution of temperatures around electroconductive pathways created by a physical vacuum deposition process on flexible textile substrates used in elastic electronics and textronics. Cordura material was chosen as the substrate. Silver with 99.99% purity was used as the deposited metal. This research was based on thermographic photographs of the produced samples. Analysis of the temperature field around the electroconductive layer was carried out using Image ThermaBase EU software. The analysis of the temperature distribution highlights the software’s usefulness in determining the homogeneity of the created metal layer. Higher local temperatures and non-uniform distributions at the same time can negatively influence the work of the textronic system.

AbstractThis study aims to validate the three-phase heat and mass transfer model developed in the first part (Three phase heat and mass transfer model for unsaturated soil freezing process: Part 1 - model development). Experimental results from studies and experiments were used for the validation. The results showed that the correlation coefficients for the simulated and experimental water contents at different soil depths were between 0.83 and 0.92. The correlation coefficients for the simulated and experimental liquid water contents at different soil temperatures were between 0.95 and 0.99. With these high accuracies, the developed model can be well used to predict the water contents at different soil depths and temperatures.
Practice patterns, attitudes, and knowledge among physicians regarding cytoreductive surgery and HIPEC for patients with peritoneal metastases
Authors: Bernaiche Tyler , Emery Erica , Bijelic Lana 
Published: April 2018

AbstractBackgroundCytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is a treatment option for patients with peritoneal metastases shown to provide improved overall survival for appropriately selected patients. However, the availability and utilization of this treatment remains limited. The aim of this survey-based study was to evaluate factors influencing physician treatment choices for peritoneal metastases.MethodsSurveys were mailed to medical oncologists and surgeons in Virginia, Maryland, and Washington, D.C. Survey questions evaluated access to HIPEC centers, prior experience with referral to HIPEC centers, opinions regarding efficacy, and knowledge regarding outcomes of CRS and HIPEC.ResultsSurveys were mailed to 2279 physicians; 116 eligible surveys were returned. Seventy-five percent of respondents would consider referral to a HIPEC center for appendiceal peritoneal metastasis, while only 50% would consider it for colon cancer and peritoneal mesothelioma. The most common reason for never referring a patient to a HIPEC center was lack of access to a HIPEC specialist (47%) followed by perceived lack of evidence for the treatment modality (31%). Five-year survival after CRS and HIPEC was underestimated while 30-day mortality was overestimated by more than half of respondents.ConclusionsReferral to HIPEC centers is underutilized among community physicians in practice. Limited access to HIPEC experts is the most common cause for lack of referral, followed by a perception of insufficient evidence for this treatment approach. Lack of familiarity with data regarding outcomes impacts referral patterns and treatment choices. Possible actions to increase awareness and appropriate utilization of CRS and HIPEC are suggested.

Authors: Vigneron Jean , D’Huart Elise , Demoré Béatrice 
Published: April 2018

Abstract

Background
Bendamustine is used for the treatment of non-Hodgkin lymphoma, chronic lymphocytic leukaemia and myeloma. The stability of bendamustine is highly dependent on temperature and chloride-ion concentration. Limited stability data are available. The objective of this work was to study the stability of the bendamustine reconstituted solution at 2.5 mg/mL and the diluted solution in normal saline and 1.5 % sodium chloride to evaluate a potential increase in stability.

Methods
A stability indicating High Performance Liquid Chromatography method with Diode Array Detection was used. A first study was carried out in glass vials and then in polyolefin containers at 0.25 and 0.60 mg/mL. Solutions were stored at room temperature and at 2–8 °C for 7 days.

Results
Stability was defined as a concentration above 95 % of the initial concentration [10]. The reconstituted solution at 2.5 mg/mL was stable for only 2 hours at room temperature and 8 hours at 2–8 °C. The stability of diluted solutions was in accordance with the manufacturer’s recommendations of 3.5 hours at room temperature and 48 hours at 2–8 °C. The addition of sodium chloride doesn’t increase the stability for preparation in infusion in daily practice.

Conclusions
The information brought by this study is an 8-hour stability of the reconstituted solution at 2–8 °C.

Published: April 2018

AbstractIntroduction: This paper examines office staff’s knowledge and obedience of rules of computer workstation ergonomics and assesses how physical activity and obedience of ergonomic rules affect the level of pain intensity reported by office staff included in the study.Material and methods: The study group consisted of 136 persons (94 female and 42 male) aged between 20 and 46 (average 44,5±12,6 years) working on computer workstations. Results. Approximately 50% of the study group were spending their free time actively (72 persons, 52,9%). Preferred forms of activity were as follows: walking (72,1%), cycling (58,1%) and physical exercise (26,5%).Results: It was found that higher rates of physical activity significantly reduced the intensity of the pain resulting from computer work. On the contrary, a statistically significant number of people occasionally involved in physical activity more often suffered the following symptoms: pain in the shoulders (p=0,0224), hips (p=0,0036) and feet (p=0,0458), and tingling and sensory loss in lower extremities (p<0,0001). It was found that study group members regularly involved in physical activity less often suffered from the pain in the shoulders (22,9% vs 50,0%,), hips (14,3% vs 44,7%,) and feet (17,1% vs 31,6%), and tingling and sensory loss in lower extremities (2,9% vs 36,8%) when compared to the group with occasional physical activity. Statistically significant lower incidence of pain was observed in the study group members conforming to the rules of ergonomics at work as exemplified through the following symptoms: increased muscle tension in the shoulder areas (38,5% vs 61,8%, p=0,0303), pain in the upper parts of the spine (26,9% vs 50,9%, p=0,0274), eye pain, tearing and burning sensation (57,7% vs 80,0%, p=0,0170).Conclusions: 1. Only a small number of study group members complied with ergonomic rules at work. 2 It was observed that physical activity has a positive effect on pain reduction. 3. Adherence to ergonomic rules at work has a significant influence on reduction of pain intensity in examined groups.

Abstract
Introduction: Cerebral palsy is a great and serious medical problem. There are no effective ways of its treatment which is the main reason of constant research into successful therapeutical methods of rehabilitation. Nowadays, the rehabilitation is based on neurodevelopmental methods which are the most effective and friendly for children. Therefore, it is important to find an extensive approach towards the rehabilitation of children with cerebral palsy according to ICF (International Classification of Functioning Disability and Health) concepts and the Polish model of rehabilitation. The fundamental objective of rehabilitation of children with cerebral palsy is to give them the possibility to live independently in the future.
Material and methods: The research involved 10 children with cerebral palsy (including 4 girls and 6 boys) aged 5 - 8 years. The average weight for girls was 13,68 kg. and boys was 15,83 kg. The average height for all examined children was 104,25 cm. to 115,00 cm. In order to determine the effectiveness of the chosen rehabilitation methods (NDT Bobath, Sensory Integration, Halliwick, hippotherapy) as well as other supporting techniques (orthopaedic equipment, kinesiotaping, arm - chairs) to the condition of research children, the analysis of the therapeutic improvement process in the space of one year was carried out. The research method was based on the completed questionnaire as well as on the assessment of the psychomotor development according to Bobath.
Results: In the examined group of children with CP, after one-year therapy, a significant improvement of the evaluated righting and balance reactions and skill abilities (p<0,05) were noticed which had a good influence on the emotions of these children.
Conclusions: On the basis of the achieved results, one may advance the thesis about the justifiability of the use of the chosen methods and supporting techniques in rehabilitation of the patients with cerebral palsy.

Market concentration and market power of the Swedish mortgage Sector – a wavelet panel efficiency analysis
Authors: Månsson Kristofer , Sjölander Pär , Shukur Ghazi 
Published: April 2018

AbstractBased on a panel wavelet efficiency analysis, we conclude that there is a systematic pattern of positive asymmetric price transmission inefficiencies in the interest rates of the largest Swedish mortgage lenders. Thus, there seems to be a higher propensity for mortgage lenders to swiftly increase their customers’ mortgage interest rates subsequent to an increase in its borrowing costs, than to decrease their customers’ mortgage rates subsequent to a corresponding decrease in the cost of borrowing. A unique contribution is our proposed wavelet method which enables a robust detection of positive asymmetric price transmission effects at various time-frequency scales, while simultaneously controlling for non-stationary trends, autocorrelation, and structural breaks. Since traditional time-series analysis methods essentially implies that several wavelet time scales are aggregated into one single time series, the blunt traditional error correction analysis totally failed to discover APT effects for this data set. In summary, using the wavelet method we show that even though the customers in the end finally will benefit from decreases in the mortgage lenders’ financing costs, the lenders wait disproportionally long before the customers’ mortgage rates are decreased.
