Published: September 2019

Mirror antenna systems are widely used in satellite and space communication systems and radio astronomy. Development of these areas requires new efficient antenna systems' design. Possible technical solution for creating an effective mirror antenna is a “hybrid” scheme, when an adaptive phased antenna array is used as an irradiator. This paper is devoted to the development of an out-of-focus irradiator based on a phased antenna array for a space communications' parabolic reflector antenna. The aim of the work is to develop an optimal design of the irradiator with the choice of the structural element of the antenna array and experimental studies of the selected structural element.The wavefront recovery method was used as a tool for selecting the irradiator configuration. The idea of this method use is to reproduce the electromagnetic field of an incident plane wave with an irradiator in order to uniformly illuminate the aperture of the antenna mirror.In order to select the structural element of the irradiator several antennas were considered: a patch antenna, a flat spiral antenna, a conical spiral antenna. The requirements for the phased antenna array element were defined. The irradiator based on the above mentioned was simulated and the irradiator geometry was optimized according to the maximum gain criterion.The maximum gain was achieved for the irradiator based on conical spiral antennas and amounted to 30.8 dB, which for the considered mirror aperture of 2.4 m is close to traditional focal schemes. The results obtained make it possible to create an adaptive antenna system able to compensate for the deviations of the mirror's shape from the theoretical profile, as well as phase distortions in the atmosphere by changing the lattice weights coefficients.

Authors: Yanukovich T. P. , Polyakov A. V. 
Published: September 2019

Due to the development of automation and control systems, methods and devices for measuring of electric current large values are of great interest. The aim of the work was to develop a schematic diagram of a distributed current strength sensor based on the Brillouin optical frequency domain analysis; to create a mathematical model of the sensor to demonstrate its work and to calculate the basic parameters of the sensor. To provide the measurement optical fiber with conductive coating is used. Between the current bus, where current is measured, and conductive coating the Ampere force arises. Strain occurs in optical fiber due to this force. Stimulated Brillouin scattering has the strain dependent characteristic frequency. Shift of the characteristic frequency allows to measure current in the bus. To measure the characteristic frequency and the location of its shift Brillouin optical frequency domain analysis is used.The mathematical model of sensor operation based on tree-wave model of stimulated Brillouin scattering is demonstrated. This model allows calculating intensity of optical signal in the fiber in dependence of characteristic frequency shift. Brillouin optical frequency domain analysis uses inverse Fourier transform to obtain pulse response.A schematic diagram of a distributed current sensor based on the method of Brillouin optical frequency domain analysis is presented. An a priori estimate of parameters of the measuring system was carried out on the basis of the mathematical model of stimulated Brillouing scattering in an optical fiber. The spatial resolution of the sensor when determining the length and location of fiber sections was 0.06 m. The resolution of the sensor was 0.22 kA, the maximum value of the current strength was 25 kA. Dependence of the sensor operation at different powers of the laser used was investigated. The refractive index change influence on the result of measurements was estimated.
Clinical approaches to cultural diversity in mental health care and specificities of French transcultural consultations: A scoping review.

Published: September 2019

Abstract
Background: Cultural context substantially affects the experience and clinical expression of psychiatric diseases, while cultural factors limit both access to and the effectiveness of care, especially for migrant families requiring the construction of specific types of services. We review the international literature on mental health services that take cultural elements into account and use these data to uncover the specificities of the French model of consultations by a group of transcultural psychotherapists.
Methods: Exhaustive review of the international literature through searches of PubMed and PsycINFO. The review includes 32 articles.
Results: The specificities of mental health services for migrant families are linked to the host country's migration patterns and citizenship model. In English-speaking countries, specialized services for ethnic minorities offer ethnic matching of the therapist and patient. In Canada, indirect transcultural consultation services have existed since the late 1990s. Australia emphasizes the networking of consultation services and professional training in cultural competence, while the Nordic countries (Sweden, Finland, Norway, and Denmark) focus management on trauma. In France, psychotherapy services, with flexible numbers of therapists involved according to the situation, have existed since 1990.
Discussion: Most initiatives place emphasis on training and supervision, in an indirect approach not specifically focused on the patient, or offer cultural matching of patient and therapist. The French transcultural approach, on the contrary, makes the family's culture and its cultural diversity an integral part of the therapy process. Scientific publications clearly demonstrate the clinical efficacy of this method.

Abstract
Background: The spinal level determined by reference of posterior superior iliac spine (PSIS) will be different because of the various sagittal posture of spine-pelvis complex. The study aimed at investigating the anatomical factors affecting the estimated spinal level of PSIS from the standpoint of spine-pelvis paraments, and provided a basis for improving the accuracy of positioning. Methods: The lumbar X-ray images of 76 patients were retrospectively analyzed. The population was classified according to the estimated level of PSIS. lumbar lordosis (LL), sacral slope (SS), pelvic incidence (PI), pelvic tilt (PT) and other parameters were measured. Then, the latent factors affecting the estimated level were filtered and obtained by One-way ANOVA and Fisher linear discriminant analysis to further summarize the imaging characteristics of different populations. Results: Three different levels of L5 (10 cases), S1 (46 cases) and S2 (20 cases) were observed. ANOVA analysis showed that LL, SS, PT, PI, SS-PT, LL-SS and lordosis of L1-L5 (LL L1-L5 ) were significantly different among the three groups ( P < 0.05). Discriminant analysis showed that LL, SS, SS-PT and LL L1-L5 were the main factors affecting the estimated level of PSIS (P < 0.05). Conclusions: The variations of morphological parameters such as LL, SS, SS-PT and LL L1-L5 can affect the estimated level of PSIS, and the level can be predicted by the discriminant function. In the study, the function is D=-4.458+0.13×LL-0.115×SS+0.45× （SS-PT）+0.39×LL L1-L5 , which proved 71.1％ of the discriminant accuracy rate.

Abstract
Introduction Colorectal (CRC) and Gastric (GC) cancers are responsible for considerable morbidity and mortality worldwide. In the North region of Brazil, these neoplasms are among the three most incident and aggressive types of cancer, constituting a severe problem of public health. Single Nucleotide Polymorphisms (SNPs) of xenobiotic metabolism and transporter genes may play a role in individual response to exposure to some of the compounds implicated in the cancer susceptibility. However, few studies have demonstrated the role of polymorphisms of xenobiotic metabolism and transporter genes in the susceptibility to CRC or GC in admixed populations. In this context, the study of variation in the activation and detoxification processes of xenobiotics may help to clarify the development of either GC or CRC in substructured populations, providing new insights about predictive diagnostic criteria in oncological investigations. MethodsWe performed an association study using 31 SNPs in 15 xenobiotic metabolism and transporter genes. The study was carried out in 121 CRC and 95 GC cases and 140 control individuals from Belém, a city which comprises a population with high levels of miscegenation, located in the Brazilian Amazon. Samples were genotyped using the QuantStudio™12K Flex Real-Time PCR System. Due to the high level of genetic admixture in the studied population, we applied a panel of 61 Ancestry Informative Marker standardized by our research group in an earlier study. Statistical analyses were performed in SPSS v.20.0 and Structure v.2.3.4ResultsThe results revealed a significant association between the increased CRC or GC risk and polymorphisms of ABCG2 (rs2231142) and DPYD genes (rs17116806, rs1801159). ConclusionsOur data suggest that polymorphisms in xenobiotic-metabolizing and transporter genes may be relevant to the susceptibility to both CRC and GC.
A novel approach to the classification of performance on inpatient perception of hospitalization experience across the US 52 states

Published: September 2019

Abstract
Background: Medical groups identified as high-performing with different approaches have been proposed for classification of performance in the literature, but no consistently-applied approach exists for identifying high performers for the benefit of healthcare providers. Most organizations classify hospitals using domain scores and assign a letter grade (e.g., from A to F in Leapfrog Groups) to the performance level. Whether bibliometrics can be an alternative for classifying healthcare givers’ performances is worthy of study. This study was performed to visualize survey results about inpatients’ perceptions of hospitalization experience for the US states using bibliometrics. Methods: We downloaded the 2014 summaries of HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Services) data. Four indices of h, PI, Ag, and x were applied to evaluate performance based on the core domains derived from the ten domain scores for each state in the US, and then displayed online dashboards to show hospitalization satisfaction across states on Google Maps. Choropleth maps were plotted for classifying the performnces into six grades using the quantiles method.Results: The top three states for hihg quality-of-care are Louisiana, Nebraska, and South Dakota using either x or Ag-index to assess. The Ag-index earns the mean correlation coefficient (=0.86) higher than the other three. The inpatient perception of hospitalization experience or the US states were classified and displayed on choropleth maps. Conclusions: The classification of healthcare performance is sensitive to the domain scores, the approach in classification, and the choice of metrics. The absence of a consistently-applied approach to identify healthcare performers impedes efforts to reliably compare, select, and reward high-performing providers. The x-index is recommended for quantifying the performance of healthcare givers in the foreseeable future.
Protozoan pathogens Blastocystis and Giardia spp. in roof-harvested rainwater: the need to investigate the role of the common brushtail possum (Trichosurus vulpecula) and other potential sources of zoonotic transmission

Abstract
Globally, protozoan pathogens are an increasingly important cause of reported disease outbreaks, with the majority of documented outbreaks between 2004 and 2010 reported in Australia. While the microbiological contamination of roof-harvested rainwater (RHRW) has been well studied, limited information is available regarding contamination with protozoan pathogens. In this study, rainwater (n = 134) and possum fecal samples (n = 20) were screened for the presence of several protozoan pathogens, including Blastocystis spp., Cryptosporidium spp., Giardia spp., Dientamoeba fragilis, and Entamoeba histolytica using the multiplex real-time polymerase chain reaction. While Cryptosporidium spp. was only detected in two possum fecal samples (10%) and Giardia spp. was only detected in three RHRW samples (2.23%, n = 134), Blastocystis spp. was detected in both possum feces (25%) and RHRW (5.22%) samples. Dientamoeba fragilis and Entamoeba histolytica were not detected in any samples. These findings highlight protozoan pathogens as a potentially important area of focus for rainwater quality assessment. Furthermore, while possums are suggested as a potential source of Blastocystis spp. in RHRW, sources of this pathogen in RHRW warrant further investigation.

Abstract
Naegleria fowleri causes the usually fatal disease primary amebic meningoencephalitis (PAM), typically in people who have been swimming in warm, untreated freshwater. Recently, some cases in the United States were associated with exposure to treated drinking water. In 2013, a case of PAM was reported for the first time in association with the exposure to water from a US treated drinking water system colonized with culturable N. fowleri. This system and another were found to have multiple areas with undetectable disinfectant residual levels. In response, the water distribution systems were temporarily converted from chloramine disinfection to chlorine to inactivate N. fowleri and reduced biofilm in the distribution systems. Once &gt;1.0 mg/L free chlorine residual was attained in all systems for 60 days, water testing was performed; N. fowleri was not detected in water samples after the chlorine conversion. This investigation highlights the importance of maintaining adequate residual disinfectant levels in drinking water distribution systems. Water distribution system managers should be knowledgeable about the ecology of their systems, understand potential water quality changes when water temperatures increase, and work to eliminate areas in which biofilm growth may be problematic and affect water quality.

Published: September 2019

This study aims to analyze technical efficiency and evaluate the effect of some sources of inefficiency in the Indonesian fishery canned firms during the period of 1990-2015. We calculate technical efficiency using the Stochastic Frontier Analysis (SFA) method with Time Varying Decay. The average of technical efficiency in this industry during the period of 1990-2015 was only 57%. It indicates that firms in this industry still encounter a problem in allocating the resources in efficient manner. However, during the period of 1994-2015, the efficiency in the Indonesian fishery canned industry has declined. We also employed the Ordinary Least Square (OLS) method to evaluate the sources of inefficiency. The results showed that eight variables affected to the efficiency in this industry, thereby it will reduce fishery product competitiveness in the future
