Ultrafast Bessel beams: advanced tools for laser materials processing
Authors: Stoian Razvan , Bhuyan Manoj K. , Zhang Guodong , Cheng Guanghua , Meyer Remy , Courvoisier Francois 
Published: April 2018

Abstract
Ultrafast Bessel beams demonstrate a significant capacity of structuring transparent materials with a high degree of accuracy and exceptional aspect ratio. The ability to localize energy on the nanometer scale (bypassing the 100-nm milestone) makes them ideal tools for advanced laser nanoscale processing on surfaces and in the bulk. This allows to generate and combine micron and nano-sized features into hybrid structures that show novel functionalities. Their high aspect ratio and the accurate location can equally drive an efficient material modification and processing strategy on large dimensions. We review, here, the main concepts of generating and using Bessel non-diffractive beams and their remarkable features, discuss general characteristics of their interaction with matter in ablation and material modification regimes, and advocate their use for obtaining hybrid micro and nanoscale structures in two and three dimensions (2D and 3D) performing complex functions. High-throughput applications are indicated. The example list ranges from surface nanostructuring and laser cutting to ultrafast laser welding and the fabrication of 3D photonic systems embedded in the volume.
The roadmap for harmonization: status of the International Consortium for Harmonization of Clinical Laboratory Results
Authors: Myers Gary L. , Miller W. Greg 
Published: April 2018

Abstract
The International Consortium for Harmonization of Clinical Laboratory Results (ICHCLR) was established to fulfill recommendations identified by an international conference convened to review the available infrastructure and challenges in achieving harmonization of results among different measurement procedures. The specific objectives of the ICHCLR are to: prioritize measurands by medical importance, coordinate the work of different organizations, and stimulate development of technical and regulatory processes to achieve harmonization. Central to these objectives is the website “www.harmonization.net” developed by the ICHCLR as an information portal designed to provide a resource center for global activities to harmonize and standardize results from clinical laboratory measurement procedures. Priorities based on medical impact are provided for measurands for which harmonization is needed or work to implement harmonization is incomplete or inactive. By making information available regarding harmonization activities in progress or planned, coordination of work to harmonize laboratory measurement procedures will minimize duplication of effort and optimize the use of limited resources. A toolbox of technical procedures developed by ICHCLR to be considered when developing a process to achieve harmonization for a measurand is presented. The ICHCLR initiated a proposal to ISO Technical Committee 212 for a harmonization protocol as the basis for calibration traceability when there are no other higher order reference system components available. The ICHCLR offers a unique service to prioritize measurands in need of harmonization and to provide a centralized approach to organize global efforts to achieve harmonization of clinical laboratory test results.

Published: April 2018

Abstract
Reference intervals are a vital part of the information supplied by clinical laboratories to support interpretation of numerical pathology results such as are produced in clinical chemistry and hematology laboratories. The traditional method for establishing reference intervals, known as the direct approach, is based on collecting samples from members of a preselected reference population, making the measurements and then determining the intervals. An alternative approach is to perform analysis of results generated as part of routine pathology testing and using appropriate statistical techniques to determine reference intervals. This is known as the indirect approach. This paper from a working group of the International Federation of Clinical Chemistry (IFCC) Committee on Reference Intervals and Decision Limits (C-RIDL) aims to summarize current thinking on indirect approaches to reference intervals. The indirect approach has some major potential advantages compared with direct methods. The processes are faster, cheaper and do not involve patient inconvenience, discomfort or the risks associated with generating new patient health information. Indirect methods also use the same preanalytical and analytical techniques used for patient management and can provide very large numbers for assessment. Limitations to the indirect methods include possible effects of diseased subpopulations on the derived interval. The IFCC C-RIDL aims to encourage the use of indirect methods to establish and verify reference intervals, to promote publication of such intervals with clear explanation of the process used and also to support the development of improved statistical techniques for these studies.

Abstract
We describe a practical fully homomorphic encryption (FHE) scheme based on homomorphisms between rings and show that it enables very efficient computation on encrypted data.
Our encryption though is private-key; public information is only used to operate on encrypted data without decrypting it.
Still, we show that our method allows for a third party search on encrypted data.
Influence of veneer thickness, mat formation and resin content on some properties of novel poplar scrimbers
Authors: Zhang Yahui , Qi Yue , Huang Yuxiang , Yu Yanglun , Liang Yanjun , Yu Wenji 
Published: April 2018

AbstractThick poplar veneers (4–8 mm) have been finely fluffed to manufacture novel scrimbers by two paving ways, namely by random and laminated mat formations. The following properties of the scrimbers were evaluated: modulus of rupture (MOR) via static bending, modulus of elasticity (MOE), compression strength (CS), shear strength (SS), water absorption rate, thickness swelling rate (TSR) and width swelling rate. The results show that utilization of fluffed thicker veneers reduced the mechanical properties to a certain extent. The TSR of the scrimber was first improved and then weakened by increasing the thickness of the veneers. The scrimber prepared from 6-mm-thick veneers showed the best waterproof performance. The random and laminated mat formations affected the surface texture significantly but the mechanical properties and dimensional stability to a lesser extent. With increasing resin content, the waterproof performance of the scrimbers was improved, which was not otherwise expected. The mechanical properties remained essentially unchanged except for the shear strength.
Numerical Simulation for Shale Gas Flow in Complex Fracture System of Fractured Horizontal Well
Authors: Yuan Yingzhong , Yan Wende , Chen Fengbo , Li Jiqiang , Xiao Qianhua , Huang Xiaoliang 
Published: April 2018

Abstract
Complex fracture systems including natural fractures and hydraulic fractures exist in shale gas reservoir with fractured horizontal well development. The flow of shale gas is a multi-scale flow process from microscopic nanometer pores to macroscopic large fractures. Due to the complexity of seepage mechanism and fracture parameters, it is difficult to realize fine numerical simulation for fractured horizontal wells in shale gas reservoirs. Mechanisms of adsorption–desorption on the surface of shale pores, slippage and Knudsen diffusion in the nanometer pores, Darcy and non-Darcy seepage in the matrix block and fractures are considered comprehensively in this paper. Through fine description of the complex fracture systems after horizontal well fracturing in shale gas reservoir, the problems of conventional corner point grids which are inflexible, directional, difficult to geometrically discretize arbitrarily oriented fractures are overcome. Discrete fracture network model based on unstructured perpendicular bisection grids is built in the numerical simulation. The results indicate that the discrete fracture network model can accurately describe fracture parameters including length, azimuth and density, and that the influences of fracture parameters on development effect of fractured horizontal well can be finely simulated. Cumulative production rate of shale gas is positively related to fracture half-length, fracture segments and fracture conductivity. When total fracture length is constant, fracturing effect is better if single fracture half-length or penetration ratio is relatively large and fracturing segments are moderate. Research results provide theoretical support for optimal design of fractured horizontal well in shale gas reservoir.
Assyrians Abroad: Expanding Borders Through Mobile Identities in the Middle Bronze Age
Authors: Highcock Nancy 
Published: April 2018

AbstractRecent work by both archaeologists and Assyriologists has characterized the main Assyrian settlement at Kaneš/Kültepe not as “colony” at all but as a place in which Assyrians fully integrated themselves into Anatolian society to create a hybridized community or “middle ground.” This paper builds upon their work by examining the ways in which Assyrians participated in such an intercultural society whilst still maintaining the bounded social category of “Assyrian.” Through the reconstruction of their civic institutions and social traditions abroad, Assyrian merchants were able to expand their mental topography of what constituted “Assyrian-ness” from northern Mesopotamia across central Anatolia. This phenomenon is framed within wider discussions of mobile societies and the Old Assyrian textual record to illustrate that a community identity founded upon the mother city of Assur and its cultural conventions continued to thrive across various political and cultural borders. Treaties and letters demonstrate that these borders were well defined and maintained by the Assyrians themselves, but concurrently, that the driving forces behind a trader’s life on the road also meant for such borders to be expanded and reconstituted. Analyzing the Old Assyrian mercantile phenomenon through the vector of mobility enables us to better understand the ways in which the Old Assyrian merchants maintained a cohesive social identity and bounded community whilst working and living in “foreign” territories. Mobility is not an inherently disintegrating force, but shape the common cultural and political institutions which act as fibers binding communities together across great distances.
Role of atrial natriuretic peptide in controlling diabetic nephropathy in rats
Authors: Singh Lakhwinder , Arya Atul , Gupta Sumeet 
Published: April 2018

Abstract

Background
Diabetes is a downregulator of atrial natriuretic peptide (ANP), resulting in reduced nitric oxide level and low expression of endothelial nitric oxide synthase by which nitric oxide level get reduced. In the present study, we examined the role of ANP in reduced nitric oxide level, which may be responsible in controlling diabetic nephropathy in rats.

Methods
Serum nitrite/nitrate ratio, blood urea nitrogen, protein in urine, urinary output, serum creatinine, serum cholesterol, kidney weight, kidney hypertrophy, renal cortical collagen content, thiobarbituric acid level, and antioxidant enzymatic activities were assessed.

Results
Treatment with lisinopril (1 mg/kg) significantly attenuated diabetes-induced elevated glucose level, cholesterol level, and protein in urine concentration. Whereas ANP at low dose (5 μg/kg) has no effect on elevated markers of diabetic nephropathy, treatment with intermediate (10 μg/kg) and high-dose ANP (20 μg/kg) significantly attenuated the diabetes-induced increased blood urea nitrogen, protein in urine, urinary output, creatinine, cholesterol, kidney weight, kidney hypertrophy, renal collagen content, and thiobarbituric acid level and reduced endogenous antioxidant enzymatic activities. High dose of ANP was more effective in attenuating the diabetes-induced nephropathy, renal oxidative stress, and antioxidant enzyme activity as compared with the treatment with low-dose ANP (5 μg/kg), intermediate-dose ANP (10 μg/kg), or lisinopril (1 mg/kg, employed as standard agent). Administration of erythro-9-(2-hydroxy-3-nonyl)adenine, a phosphodiesterase-2 inhibitor (3 mg/kg), in combination with high-dose ANP significantly attenuated high-dose ANP induced ameliorative effects in diabetic nephropathy.

Conclusions
Taken together, these results indicate that diabetes-induced oxidative stress and lipid alterations may be responsible for the induction of nephropathy in diabetic rats. ANP at intermediate and high doses have prevented the development of diabetes-induced nephropathy by reducing the cholesterol level, protein in urine concentration, and renal oxidative stress and by increasing the nitrite/nitrate ratio, certainly providing the direct nephroprotective action.
Anti-ulcerogenic effect of the methanol extract of Chasmanthera dependens (Hochst) stem on male Wistar rats
Authors: Tijani Stephanie Abiola , Olaleye Samuel B. , Farombi Ebenezer O. 
Published: April 2018

Abstract

Background
Oxidative stress and free radical-mediated processes have been implicated in the pathogenesis of indomethacin-induced gastric ulcer. This study investigated the ability of the methanol extract of Chasmanthera dependens to protect the gastric mucosal from oxidative damage induced by oral administration of indomethacin in rats.

Methods
The C. dependens stems were chopped into pieces, air-dried, and pulverized into powder. One kilogram of the powder was macerated in 1 L of methanol for 72 h. The mixture was filtered and evaporated using rotatory evaporator to obtain the extract of C. dependens. Adult male rats were divided into eight groups of six animals per group and were pretreated orally with the methanol extract of C. dependens (200, 400, and 800 mg/kg) or cimetidine (CIM), a standard drug (50 mg/kg), for 7 days. Gastric ulcer was induced orally with indomethacin. Ulcerogenic parameters, oxidative stress indices, and histopathological examination of the stomach were assessed to monitor the gastroprotective potential of C. dependens stem.

Results
Indomethacin caused severe gastric mucosa damage and significant reduction in the gastric mucosa antioxidant system with concomitant increase in the level of lipid peroxidation. Pretreatment with the methanol extract of C. dependens or CIM significantly reduced the formation of ulcer at the different doses administered. Similarly, pretreatments with the extract or CIM improved the antioxidant system, decreased acid output, lipid peroxidation, and improved the architecture of the gastric mucosa in ulcerated rats.

Conclusions
The results show the gastroprotective effect of the methanolic extract of C. dependens, which may be attributed to its antioxidant properties.

Published: April 2018

Abstract
The Rio Grande Valley (RGV) has been impacted by various hurricanes throughout history. While Hurricane evacuation has been studied extensively in other contexts, there is limited systematic research on the warning and response to a large-scale severe weather event in South Texas. This study attempts to understand the evacuation decision-making behavior of Southern residents in the event of a Hurricane making landfall over the Rio Grande Valley. The study uses an online survey questionnaire with 1060 participants: 275 students attending the University of Texas-Rio Grande Valley and the remaining 785 are members of the community. Throughout the course of the study, information was gathered about selected elements: demographic characteristics, living conditions, the following and awareness of authority recommendations, decision maker roles, reasons for not wanting to leave a disaster-prone area facing an emergency, perception of a safe place, and expected help from both, governments and non-governmental organizations (NGOs) during evacuation that could impact residents’ evacuation decision. Findings reveal there are a number of individuals who will remain in their place of residence, even in the deadliest of hurricane Category 5. The study provides complex factors influencing the nature of evacuation decision-making of individuals who are Hispanics living in a unique geographical location of RGV.

Published: April 2018

Abstract
Diabetes Mellitus (DM) is one of the biggest healthcare and financial problems worldwide. The disease is strongly associated with microvascular and macrovascular complications, causing co-existing diseases like Diabetic Retinopathy, Diabetic Neuropathy and Diabetic Nephropathy. Annual healthcare expenditures for diabetes treatment and complications prevention cost 727 billion USD in year 2017.
Diabetes Mellitus, Diabetic Retinopathy and Diabetic Retinal Neuropathy are closely related diseases - originating from incorrectly controlled glycemia, blood pressure and lipid levels in the course of increasing resistance of the body tissues to insulin.
Irrespectively of thorough programs for Diabetes Mellitus prevention and treatment, Diabetic Retinopathy management requires targeted treatment strategies for both microvasculopathy and retinal neurodegeneration, to delay disease severity course and risk of blindness.
The study and conclusions in this article are based on web-available data and officially published articles related to the diabetes mellitus and associated diseases – Diabetic Retinopathy and Diabetic Retinal Neuropathy. The articles have been reviewed and analyzed to assess mutual relations between the discussed diseases.

Abstract
Introduction. In women with diabetes, the changes that accompany menopause may further diminish glycemic control. Little is known about how hormone replacement therapy (HRT) affects glucose metabolism in diabetes. The aim of this study was to examine whether HbA1C levels are influenced by current HRT among postmenopausal women with type 2 diabetes.
Methods. A total of 40 postmenopausal women with type 2 diabetes were enrolled. All of them fulfilled the criteria of natural menopause, with intact uterus, low estrogen levels (E2) and high follicle-stimulating hormone (FSH) levels. Half of them (20 women) were assigned to take HRT (DM-HRT group). The other half (20 women) were assigned to the control group, those who did not take HRT (DM-non HRT group). HRT consisted of 17 β-estradiol (E2) 1 mg and drospirenone (DRSP) 2 mg. Fasting plasma glycemia, insulinemia and HbA1C were followed in both groups throughout 12 months.
Results. The mean age was 49 years (SD±3,3) and 48,5 (SD±3.1), respectively. HRT was associated with statistically significant decrease in serum fasting glucose, HbA1C and insulinemia levels in the DM-HRT group. There was no significant reduction in glucose levels and HbA1C together with no significant increase in insulinemia levels in the DM non-HRT group throughout 12 months.
Conclusion. HRT was associated with statistically significant decrease of plasma glucose levels and HbA1C level. Larger clinical trials are necessary to understand whether HRT may improve glycemic control in women with diabetes, especially when it is given shortly after entering menopause.

Published: April 2018

Abstract
Ferromagnetic poles in a magnetic transmission gear require particular attention during their design process. Usually, during the numerical simulation of these devices the effects of hysteresis for loss estimation are neglected and considered only during post-processing calculations. Since the literature lacks hysteresis models, this paper adopts a homogenized hysteretic model able to include eddy current and hysteresis losses in 2D laminated materials for iron poles. In this article the results related to the hysteresis in a magnetic gear are presented and compared to the non-hysteretic approach.

Authors: Aziz Asim , Jamshed Wasim , Aziz Taha 
Published: April 2018

Abstract
In the present research a simplified mathematical model for the solar thermal collectors is considered in the form of non-uniform unsteady stretching surface. The non-Newtonian Maxwell nanofluid model is utilized for the working fluid along with slip and convective boundary conditions and comprehensive analysis of entropy generation in the system is also observed. The effect of thermal radiation and variable thermal conductivity are also included in the present model. The mathematical formulation is carried out through a boundary layer approach and the numerical computations are carried out for Cu-water and TiO2-water nanofluids. Results are presented for the velocity, temperature and entropy generation profiles, skin friction coefficient and Nusselt number. The discussion is concluded on the effect of various governing parameters on the motion, temperature variation, entropy generation, velocity gradient and the rate of heat transfer at the boundary.
