Coupling reduction using a novel circular ripple-shaped decoupling mechanism in a four-element UWB MIMO antenna design

A 4*4 multiple-input multiple-output (MIMO) antenna with compact size and good isolation is presented for UWB applications. The concept of polarization diversity is here discussed and employed to satisfy contemporary wireless communication systems requirements. In the proposed antenna, the utilization of a novel circular ripple-shaped decoupling structure and a matching structure are presented to minimize mutual coupling of the inter-elements and enhance adaptation. Experimental results show a bandwidth range from 2.96 to 11.4 GHz with a good reflection coefficient which is S 11 < −12 dB, high isolation S 21 and S 31 < −20 dB, good Envelope Correlation Coefficients ECC21 and ECC31 < 0.03, Diversity Gain DG21 and DG31 equal to 8.75, and a Total Active Reflection Coefficient (TARC) less than −12 dB. The antenna also exhibits a maximum gain of about 4 dBi with a maximum efficiency of 70% which proves that this antenna is a potential candidate for UWB applications.
Variation for virulence on Brassica napus L. amongst Plasmodiophora brassicae collections from France and derived single‐spore isolates

Variation for virulence was examined amongst 20 field collections of Plasmodiophora brassicae from France. Out of the 10 brassica lines tested, seven reacted differentially to inoculation; of these, two oilseed rape cultivars exhibited previously unreported differential responses. Some of the differential lines used previously to classify pathotypes of P. brassicae were susceptible to all collections, suggesting that pathogen populations in France may be different from those reported elsewhere. Good pathotype discrimination was obtained using a set of three cultivars of Brassica napus. Five pathotypes, P 1 , P 2 , P 3 , P 4 and P 5 , were detected and their occurrence was unrelated to host type. Pathogenic variation amongst 17 single-spore isolates derived from three field collections was studied, and five pathotypes were identified. Four isolates were classified as pathotype P 1 , pathogenic on all three differential hosts, and eight as pathotype P 4 , pathogenic on none of the three differentials. The five other isolates were classified as pathotypes P 3 , P 6 and P 7 , the latter two expressing patterns of reaction not observed for field collections. The fractionation of different individual pathotypes from one original spore suspension confirmed the genetic heterogeneity of field populations of P. brassicae.
Soluble plasma programmed death 1 (PD-1) and Tim-3 in primary HIV infection

&NA; Soluble forms of the coinhibitory receptors programmed death 1 (PD-1) and Tim-3 exist, but their relationship with T-cell surface expression remains unclear. When measured by an enzyme-linked immunosorbent assay in plasma, soluble PD-1, and soluble Tim-3 were elevated during primary HIV infection, decreased on antiretroviral therapy to levels found in controls, and correlated with cell surface expression. We conclude that soluble PD-1 and soluble Tim-3 are easy to measure biomarkers of immune exhaustion which potentially eliminate the need for flow cytometry.
CVD growth of monolayer WS2 through controlled growth temperature and time

Abstract Recently, two-dimensional Transition metal dichalcogenides (TMDCs) have attracted widespread attention due to their unique electrical and optical properties. Specially, the monolayer WS2 has high photoluminescence intensity and short response time, and has high application potential in optoelectronic devices. Here, a method for synthesizing single-layer WS2 crystal by atmospheric pressure chemical vapor deposition (CVD) is reported. The triangular and regular hexagonal monolayer WS2 crystals are directly synthesized on Si/SiO2 substrate. Moreover, the measurement results show that the quality of the single-layer WS2 crystal can be further improved through adjusting the growth parameters, such as growth temperature and growth time.
Food becoming compost: encountering and negotiating disgust in household sustainability

ABSTRACT Human encounters with waste can trigger reflections on taken-for-granted assumptions about consumption. Taking this observation as its starting point, this paper explores whether and how the introduction of the kitchen caddy and food waste composting at the municipal scale generates new environmental subjectivities in Australian homes. Using visceral research methods, the paper shows that, other than participation in municipal composting, close encounters with food becoming compost do not trigger more experimental or sustainable relationships with food. Rather, they trigger new configurations of cleanliness, tidiness and storage as participants seek to stabilise their home against the disruptive sight, smell and touch of food becoming compost. In unsettling the boundaries between humans and nonhumans, and cleanliness and chaos, food becoming compost produces visceral disgust among residents who are primed through modern home cultures to maintain cleanliness, control and the prevention of nonhuman intrusions at home. The success of municipal composting thus hinges on households’ commitment to ‘sustainability work’ in placing, storing, cleaning and sealing food to reconfigure the modern home for waste recovery. Reconceptualising municipal composting as a co-production of sensory engagement and household practices, we centre a visceral politics of household sustainability at the heart of municipal composting and resource management.
Exercise participation has increased in patients with Rheumatoid Arthritis: A cross-sectional comparison between two Dutch RA cohorts

Objective: This study evaluates exercise participation in patients with rheumatoid arthritis (RA) and the percentage of patients that meet the recommended level of physical activity (at least 150 minutes per week moderate-intensity physical activity) in two cross-sectional questionnaires in 2013 and 2016 in two Dutch RA cohorts. Methods: In 2013, a cross-sectional study was performed among 740 patients with RA from seven outpatient clinics from the Dutch DREAM registry. Subsequently in 2016, 498 patients with RA of the outpatient clinic of the Bernhoven Hospital (member of the DREAM registry) participated in a similar study. In both years, patients filled in an identical questionnaire about exercise participation (frequency and duration). In 2016, items about self-efficacy to become more physically active were added to the questionnaire. Results: In 2016, patients with RA spent significantly more minutes per week in exercise activities compared to 2013: 180 (150–450) and 120 (60–225) minutes per week, respectively (P<0.001). The percentage of patients with RA who met the recommended physical activity level increased from 25% in 2013 to 57% in 2016. Almost half (44%) of the non-exercisers reported feeling confident to become more physically active. Conclusion: Compared to 2013, RA patients participated in 2016 more frequently and spent more minutes per week in exercise activities. This resulted in a higher percentage of patients who met the recommended physical activity level. A personalized physical activity program, with a focus on identifying barriers and setting personal goals, might further increase the physical activity level of patients with RA.
Teaching product development through an internet scenario: description of the concept

A description is made of the concept of an Internet-based product development scenario. This scenario evolved from an engineering teaching method employed since 1997, which is based on the use of active didactic techniques to simulate the design of an ideal product in a fictitious company, with characters that represent typical functions in the development process of a new product. The original scenarios were conceived to be executed through physically attended courses. The new proposal aims to add to the positive results achieved by its predecessor initiatives based on e-learning tools and on the use of educational techniques derived from artificial intelligence, which allow the deficiencies reported by trainees and instructors in evaluations of the courses given under the old concept to be overcome. The article presents the original concept of the scenario with its outcomes and limitations, as well as the new concept, the way in which the limitations of the previous scenario are overcome and an application of the new scenario. It is concluded that the new usages given to the elements of the original scenario, associated with available Internet tools and the adoption of the case-based reasoning concept, render the new concept free of the described limitations.
Effect of feeding time and frequency on the growth and feed utilization of African catfish Clarias gariepinus (Burchell 1822) fingerlings

The effects of feeding time and frequency on the growth, feed utilization and survival of Clarias gariepinus (Burchell 1822; family Clariidae) fingerlings were evaluated in a 25-day study. Groups of African catfish with an initial individual weight of 0.98 6 0.02 g were offered feeds continuously for 24 h, or during the day or night at different time intervals, with varying meal size. The growth rate was significantly affected by meal times. Widely practised day time feeding with three equal size meals a day gave the lowest growth and highest food wastage. The growth rates of fish fed continuously or during night time following their feed demand were significantly higher with lowest food conversion ratios and food wastage.

Мета. Класичні алгоритми пошуку найкоротшого шляху на графі, що лежать в основі наявних протоколів маршрутизації, які сьогодні використовують у комп’ютерних мережах, в умовах постійної зміни завантаженості мережі не можуть привести до оптимального рішення в реальному часі. У зв’язку з цим метою статті є розробити методику визначення оптимального маршруту в об’єднаній комп’ютерній мережі. Методика.

Nowcasting Manufacturing Value Added for Cross-Country Comparison

Manufacturing Value Added (MVA) is the key indicator of a country's industrial production. In order to facilitate international comparisons it is published in UNIDO's International Yearbook of Industrial Statistics for a large set of countries. Because of a time-gap of at least one year between the latest year for which data are available and the year for which MVA data must be reported in the Yearbook, nowcasting methods are used to fill in the missing data up to the current year. We propose a methodology that exploits the relationship between MVA and GDP and produces reliable nowcasts of MVA based on figures of GDP growth rates available from external sources.
A review of the treatment of male pattern hair loss

ABSTRACT Introduction Androgenetic alopecia is a common hair loss disorder affecting up to 80% of males by the age of 80. It is characterized by androgen related progressive thinning of hair in a defined pattern. It results in diminished self-esteem, reduced confidence and distress in affected men, irrespective of age or stage of baldness. An effective treatment for hair baldness is needed. Areas covered In androgenetic alopecia, hair follicles undergo progressive miniaturization. Genetic factors and androgens are key role-players in disease pathogenesis. Herein the authors review the pharmacologic treatment of androgenetic alopecia, which involves 5 alpha reductase inhibitors, minoxidil and prostaglandins. Non-pharmacologic approaches are also explored. Expert opinion Androgenetic alopecia progresses over time and although the current available medical treatments like finasteride and minoxidil are effective in arresting the progression of the disease, they allow only partial regrowth of hair at its best. Early treatment achieves a more optimal outcome. Non-pharmacologic treatments like PRP can be considered in patients refractory to medical treatment.Abbreviations: MPHL: male pattern hair loss; AGA: androgenetic alopecia; DHT: dihydrotestosterone; 5AR: 5-alpha-reductase; VEGF: vascular endothelial growth factor; PG’s: prostaglandins (PG’s); PGD2R: prostaglandin D2 receptor; VPA: valproic aid; SR: Serenoa Repens; PRP: platelet-rich plasma; PDGF: platelet derived growth factor; TGF: transforming growth factor; ERK: extracellular signal-regulated kinase; PKB: protein kinase B; LLLT: low-level laser therapy; ROS: reactive oxygen species; RCT: randomized control trial; SFRP1: secreted frizzled related protein 1; DP: dermal papilla; PDE5: phosphodiesterase 5
Stochastic seasonal rainfall simulation model for Irbid region, Northern Jordan

ABSTRACT A stochastic hourly simulation model is developed for the synthesis of the rainfall pattern in the northern part of Jordan. The generation of synthetic rainfall data is an attempt to provide longer data sequences. The simulation model is based on statistical properties of rainfall data for three stations in the Northern region of Jordan for the period 1975–2004. The mean and variances of important rainfall characteristics were reasonably well preserved in the synthesized data. The simulated characteristics include the duration, total depth and depth at 50% duration and mass curves of the storms. The intensity-duration-frequency curves generated by this model compared well with locally available curves. The resulting IDF curves based on the stochastically generated storm sequences are usually used for flood estimation in urban/rural watersheds. Using the resulting IDF curves is highly recommended for rigorous, efficient and safe design of hydraulic structures and flood protection works.
Qualitative and Quantitative Evaluation of the Make Safe Happen App: Mobile Technology–Based Safety Behavior Change Intervention for Parents

Background Nearly half of the unintentional injuries in children happen in and around the home; many of these injuries are preventable. Providing parents and caregivers with proper injury prevention information that is easily accessible may help them make their homes safer for children. Objective The aim of this study was to evaluate parental injury prevention awareness and home safety behaviors, motivations for and challenges to taking injury prevention and safety actions for parents as well as user experience following the use of the Make Safe Happen mobile app. Methods A total of 40 parents with children aged 0-12 years living in Columbus, Ohio, participated in 1 of 5 focus group discussions following the completion of (1) a pretest survey, (2) use of the Make Safe Happen app, and (3) a posttest survey. Results Following the use of the Make Safe Happen app, parents reported a significant increase in injury prevention awareness and completed 45% more home safety behaviors in and around their homes. Nearly all of the parents felt the app provided them with the information needed to make their home safer for their children; the great majority of parents intended to make such changes in the future. Conclusions The combination of qualitative and quantitative data collection allowed for rich data capture and provided a deeper understanding of parents’ safety knowledge, behaviors, app use, and decision making regarding child injury prevention in and around the home. The Make Safe Happen app provides the information and motivation parents and caregivers need to help them take steps to prevent child injuries that may occur in and around their homes.
A Novel Prognostic Approach for RUL Estimation With Evolving Joint Prediction of Continuous and Discrete States

In this paper, we propose a novel prognostic approach for remaining useful life estimation (RUL) with evolving joint prediction of continuous and discrete states which represent the signals and health states of systems respectively. The predictors are built with evolving capability of adapting structures and parameters online to capture the dynamic characteristics of systems during runtime. Moreover, the discrete states can be determined dynamically during the construction of the predictors for systems operating under different environments. In the testing phase, the optimum predictor for predicting continuous and discrete states jointly is chosen under the error and distance criteria. The RULs are estimated conveniently once the predicted signals fall into failure mode based on a distance metric. In order to validate the performance of the proposed approach, the widely used turbofan engine datasets are taken into consideration. Experimental results demonstrate the reasonability and superiority of the proposed approach compared to other approaches.
Oral exclusive enteral nutrition induces mucosal and transmural healing in patients with Crohn’s disease

Abstract Background and aims Mucosal healing is regarded as a clinical endpoint of Crohn’s disease (CD), and transmural healing is correlated to the concept of deep remission. Current therapies to induce mucosal and transmural healing in CD are not satisfactory. Exclusive enteral nutrition (EEN) is underestimated therapy and its value has not been fully evaluated. Our aim was to investigate the efficacy of oral EEN for inducing mucosal and transmural healing in CD patients. Methods This was a prospective, single-center, open-label study including diagnosed CD children and adults conducted between January 2015 and December 2016 in the Sixth Affiliated Hospital of Sun Yat-sen University. All patients were treated with oral EEN and underwent paired assessment at baseline and completion using C-reaction protein, erythrocyte sedimentation rate, platelets, hemoglobin, body mass index, CD activity index, simple endoscopic score for CD and bowel sonography. Azathioprine was combined to prevent relapse. Results In this prospective observational study, 29 CD patients with an average age of 28.9 years were identified. After oral EEN treatment, 23 patients (79%) achieved complete mucosal healing, and the mean time to reach mucosal healing was 123 days (ranged from 50 to 212 days). Although only five patients (17%) achieved transmural healing, a significant reduction was observed in bowel-wall thickness (9.41 ± 3.06 vs 4.97 ± 1.76 mm, P < 0.001) and a significant improvement was observed in complications (including fistulas, abscess, ascites, stricture) assessed by bowel sonography (all P < 0.05). Conclusions Oral EEN therapy is highly effective for inducing mucosal healing in CD patients. Both CD patients at active stage and those at clinical remission show excellent clinical response to oral EEN.
A Comparative Study between the Effect of Nerve Growth Factor and All-Trans Retinoic Acid versus their combined use on Taxol Induced Peripheral Neuropathy in Adult Male Albino Rat

Introduction: Peripheral neuropathy is a major side effect of chemotherapy. Nerve growth factor induces peripheral nerve regeneration. Retinoids play a significant role in neural growth. This study aimed to investigate the curative effect of either recombinant human nerve growth factor (rh-NGF) or all trans-retinoic acid (ATRA) alone or together on taxol induced peripheral neuropathy. Materials and methods: Fifty two male albino rats were divided into five groups. Group 1was control group. Group 2 was i.p. injected with taxol (2mg/kg) on days 1, 3, 5, and 7. Group 3 received taxol as in group II then at the 10th day it was i.p. injected with NGF (10ug/kg daily for 20 days). Group 4 received taxol as in group II then at the 10th day it was i.p. injected with ATRA (25mgkg daily for 20 days). Group 5 received taxol as in group II then it was i.p. injected with rh-NGF and ATRA at the 10th day with the same previous dose. Neurophysiological assessment was done for sensory and motor nerve conduction velocity and amplitude as well as thermal pain threshold. Sections of sciatic nerve were prepared for immunohistochemichal and electron microscopic studies. Results: Taxol injected animals exhibited signs of peripheral neuropathy at the 10th day after the first dose of taxol. There was a significant decrease in sensory and motor conduction as well as prolongation in thermal pain threshold. Myelinopathy (splitting, ovoid fragments and invagination) and axonapathy (compressed irregular axoplasm, myelin figures and destructed mitochondria) were seen in the histological examination. Glial fibrillary acidic protein immunoreactive positive cells were significantly increased. rh-NGF and ATRA could ameliorate the electrophysiological and the histological changes. Their combined use had the best result. Conclusion: This study concluded that the use of rh-NGF and ATRA combination could improve taxol induced peripheral neuropathy in male albino rats.
Patterns of Endopolyploidy During Seedling Development in Cabbage ( Brassica oleracea L.).

Flow cytometric analysis of nuclear DNA contents of somatic tissues of cabbage ( Brassica oleracea L.) has revealed extensive endopolyploidization, resulting in tissues that comprise mixtures of cells with different DNA contents, ranging from 2C to 16C. Patterns of endopolyploidy are specific to each developmental stage. Multiple polyploidy was not present in the embryos of dry seeds. Rapid endoreduplication occurred in the radicle and the hypocotyl of the embryos during seed germination. Further endoreduplication cycles were detected in all tissues except those of the shoot tips. In five cabbage cultivars tested, seedlings contained cells of four ploidy levels, corresponding to 2C, 4C, 8C and 16C. Multiploidy may be an integral part of differentiation programs in cabbage plants. The biological significance of endoreduplication in cabbage plants is discussed.
Patch antenna design using the gA and the binary method for dual-band applications

This study proposes an innovative patch antenna design for multi-band operation and high radiation efficiency. The design target is the structural shape of a patch and a ground plane. The operating range of patch antenna is set to both the 5G band (3.4−3.7 GHz) and the Bluetooth range (2.4−2.48 GHz). The design process follows two steps, the genetic algorithm (GA) and the binary method. Although the GA has been widely used for patch antenna design, however, it is hard to improve the performance only using the GA due to its restriction on design constraints. Therefore, this study proposes the successive application of the binary method after the GA to derive a unique topological shape of a patch antenna. The application of the binary method enables the design constraint for bandwidth enhancement. Design results are verified through experimental measurements using fabricated antennas.
