Abstract
The aim of this study is to determine the optimal parameters for the separation of glucose-fructose syrup sugars into glucose, fructose, and oligosaccharides. A mathematical model of chromatographic separation of glucose-fructose syrup (GFS) was constructed. During the optimization of the chromatographic separation process, it was found that the most significant parameter affecting the purity of the fructose yield is the dry matter content. In the course of research, it was found that the dry matter content of 30% is optimal for separating glucose-fructose syrup, at separating the use of this parameter made it possible to obtain a carbohydrate composition with a content of fructose 93%, glucose 5% and oligosaccharides 2%. This is the highest yield of fructose when separated by ion exchange resins of company “Purolite” brand PCR641Ca.

Abstract
Beet pulp has a high feed value, but after pressing it has a sufficiently high humidity, which leads to rapid spoilage. One of the ways to stabilize the quality of beet pulp is drying with superheated steam of reduced pressure. Mathematical modeling of heat transfer during convective drying of beet pulp is proposed. A feature of the model is the description of the drying process, which ensures its high intensity due to high heat and mass transfer ratios and preserves the quality of the finished product as a result of the process at a reduced pressure of transfer medium. In the period of a constant drying speed, dehydration of macroscopic pores topologically related to the sample surface, which are characterized by a relatively low binding energy of water molecules with the liquid phase, is taken into account. According to experimental data, the proportion of water content in these pores is 60…70% of the total moisture content. In the final stage of this period, an increase in the binding energy occurs due to the removal of water from microcapillaries, which is explained by the formation of structured clusters in thin wetting films of water molecules. The change in steam temperature as a result of passing through the product layer was 8 … 10 K, and the relative temperature change was 5 … 10%. The parameters of the models were identified in the following range of parameters: superheated steam temperature 393 … 453 K; speed of superheated steam 3 … 5 m/s; the pressure inside the drying chamber is 40 … 100 kPa; the specific load of the product on the grate is 8 … 24 kg/m2. The interpretation of the simulation results is presented by the dependences of the temperature difference between beet pulp and heat carrier T on the temperature of superheated steam Ts at various pressures P: 1 - 100 kPa; 2 - 80 kPa; 3 - 60 kPa; 4 - 40 kPa; υ = 4 m/s; at various specific loads of beet pulp on the gas distribution grid qsp: 1 - 8 kg/m2; 2 - 16 kg/m2; 3 - 24 kg/m2; υ = 4 m/s; P = 60 kPa and various speeds of superheated steam υ: 1 - 5 m/s; 2 - 4 m/s; 3 - 3 m/s. A sufficient convergence of the results was ensured, in which the deviation of the calculated data from the experimental data did not exceed 12, 5% in absolute value. The obtained results of the simulation can be used in the operational control of the technological parameters of the process of drying beet pulp with superheated steam of reduced pressure with a restriction on the temperature mode due to the receipt of a high quality product.

Published: December 2020

Abstract
Malpractice is one of the serious issues faced in examination hall. The candidates will be examined thoroughly in the entrance itself. If they are found with possessing the electronic devices, the PGD (Paper Gadget Detector) will detect it. LCD (Liquid Crystal Display) displays the values and an alarm system will be used to give a warning to them. The proposed system is to search the candidates who are carrying the hidden written paper to the exam hall. The searching of hidden written paper can be obtained from Rectangular Microstrip Patch Antenna (RMPA). Here RMPA acts as a sensor which is used to detect the hidden material. This sensor can detect the target based on the permittivity value of each material. The sensors used in this study can be adjusted according to the values of blank paper and also to identify something written in the paper with different densities. The designed antenna has been simulated using Advanced Design System (ADS). The designed antenna (single element and 4 elements) has been compared in terms of various parameters like Gain, Efficiency, Directivity and Radiation Pattern etc.

Abstract
In this paper, medical image retrieval is done in an effective manner by using convolution neural network (CNN). This proposed system locates reference tags and classes the DICOM images using image processing techniques and retrieval of images are done by using GUI panel. First, the deep learning technique is used to extract powerful features of the image for tag description. Conversely, this technique performs tag matching directly by passing suitable parameters which recognizes the classes as queries. The comparison features are able to capture the general form of the input image and its class based on image tags. Here, we have used a collection of 22 classes of database to demonstrate the efficiency of our system. The experimental results show the classification of images by deep learning algorithm which is used to gain the rate of retrieval accuracy by using MATLAB.

Abstract
Emotions play a vital role in human living and are correlated with every single word which is being spoken, without them life will be saturated and irrelevant. Understanding of the real apparent facial expressions might be difficult because part of the emotion might not be revealed outside by everyone. In the proposed method, the emotions of the human are analyzed in two different ways so that the real hidden emotion of the subject can be detected. Every human has unique brain waves, which gives better accuracy than other techniques. It ensures that the facial expression exhibited outside is real or not. The emotion analyzed will be useful in treating the person with high mental stress and also infinding the emotion of differently abled person who requires medical treatment.

Published: December 2020

Abstract
The problem of cognitive construction of consolidating mechanisms by analyzing the phenomenon of common sense as the cognitive basis of solidarity, leading to a stable integrity of ethnic structures, is considered. The work uses a system analysis, in which the content of intelligence and ethnic structures are understood as integral systems capable of deep integration. It was found that the presence of ethnicity at the borders of social and biological transforms it into a phenomenon with a high degree of transformation, and especially in the imaginary space of identity. A cognitive mechanism for constructing identification, which ultimately generates certain models of ethnic behavior, seems to be a systemic element that allows any ethnic images to function. Common sense is one of the methods of constructing ethnic, goal-oriented activity. It can potentially act not only as a source of everyday communication, but also initiate both internal and external cooperative activities of ethnic entities united by an understanding of the common social good, including the good of the planetary. The authors make an attempt to comprehend the cognitive conditions for the functioning of ethnicity through the prism of the concept of common sense - the universal anthropological basis of a conscious social good. Common sense defines historical memory, operational reactions in the moment of the present, and a joint vision of the future. This important ability is based on a common basis for any ethnic group - the biopsychosocial nature of the cognitive capabilities of most members of the group. It is in this process of collective self-awareness that social intuition manifests itself, that is, such an integral socio-psychological characteristic of the subject of social action, which includes the ability to effectively predict the development of social situations.

Abstract
Fuel electrode supported solid oxide cells (SOCs) have been developed on an industrial scale using the aqueous tape-casting technique. The NiO–yttria-stabilized zirconia Y2O3–ZrO2 (YSZ) fuel electrode and YSZ electrolyte have been manufactured by multilayer co-laminated tape casting. Details of the tape-casting slurry formulations are described and discussed. Two types of cells were fabricated with different microstructures of the NiO–YSZ support discussed. Good electrochemical performance and stability in SOFC mode at 750 °C and 0.7 V for both button cells reaching around >0.75 W cm−2 and with no measurable degradation after >700 h were observed. The selected cell was scaled up to large-area cells (36 cm2 of the active area) and electrochemically tested at 750 °C in a single repetition unit (SRU) in SOFC (Solid Oxide Fuel Cell), SOEC (Solid Oxide Electrolysis Cell) and co-SOEC (Solid Oxide co-Electrolysis Cell) mode, and in a short-stack of two SRUs in SOFC mode. A current up to 17 A was obtained at 1.4 V (0.7 V cell−1) with the short-stack configuration in SOFC mode, corresponding to ∼0.5 A cm−2 and 24 W. The performances of the aqueous-based SOC cells can be considered highly remarkable, thus supporting the success in scaling the fabrication of SOC stacks using more environmentally friendly processes than conventional ones.
Colossal grain growth in Cd(Se,Te) thin films and their subsequent use in CdTe epitaxy by close-spaced sublimation

Published: December 2020

Abstract
Many technologies deposit thin films on inexpensive substrates, resulting in small grains due to classic nucleation and grain growth theory. For example, state-of-the-art solar cells are made by depositing CdSeTe and CdTe layers on inexpensive glass coated with nanocrystalline transparent conducting oxides (TCOs), like SnO2. Characteristically, the grain size of these films is on the order of the film thickness, i.e. a few microns. CdTe small-grain films have poor electro-optical properties and require CdCl2 passivation which fails to fully passivate grain boundaries, causes carrier compensation, and prevents implementing other II–VI alloys and materials to improve performance. Here, we present a method to increase grain size to 1 mm in CdSexTe1−x thin films deposited on glass/TCO substrates without CdCl2 treatment. The colossal grain growth is driven by mechanisms distinct from classic nucleation, grain growth, and Ostwald ripening and only occurs at low selenium content (x ∼ 0.1). We also demonstrate how these films can serve as templates for subsequent large-grain epitaxy of other compositions like CdTe, again without exposure to CdCl2. The results open new paths for thin film solar cell technology, and thin film devices in general.

AbstractMotivationAnalysis of rare variants in family-based studies remains a challenge. Transmission-based approaches provide robustness against population stratification, but the evaluation of the significance of test statistics based on asymptotic theory can be imprecise. Also, power will depend heavily on the choice of the test statistic and on the underlying genetic architecture of the locus, which will be generally unknown.ResultsIn our proposed framework, we utilize the FBAT haplotype algorithm to obtain the conditional offspring genotype distribution under the null hypothesis given the sufficient statistic. Based on this conditional offspring genotype distribution, the significance of virtually any association test statistic can be evaluated based on simulations or exact computations, without the need for asymptotic approximations. Besides standard linear burden-type statistics, this enables our approach to also evaluate other test statistics such as variance components statistics, higher criticism approaches, and maximum-single-variant-statistics, where asymptotic theory might be involved or does not provide accurate approximations for rare variant data. Based on these P-values, combined test statistics such as the aggregated Cauchy association test (ACAT) can also be utilized. In simulation studies, we show that our framework outperforms existing approaches for family-based studies in several scenarios. We also applied our methodology to a TOPMed whole-genome sequencing dataset with 897 asthmatic trios from Costa Rica.Availability and implementationFBAT software is available at https://sites.google.com/view/fbatwebpage.

Authors: Wu Dong , Zhou Bin , Yang Jian , Qiu Fa-bo , Hu San-yuan , Zhan Han-xiang 
Published: December 2020

Abstract

Background:

Chemoprevention effect of aspirin for pancreatic cancer (PC) remains unclear. Here we performed an updated systematic review and meta-analysis to investigate the real association between aspirin consumption and risk of PC.

Methods:
PubMed, Web of Science, EMBASE and the Cochrane Database were systematic searched to identify the potential studies. Odds ratio (ORs) with 95% confidence intervals (CIs) were applied to assess the strength of associations.

Results:
Thirteen studies and approximately 28,440 participants were included. Aspirin significantly reduced the incidence of PC (OR, 0.82; 95% CI, 0.73–0.93) in case-control studies. However, the overall results did not reveal an obvious association (OR, 0.92; 95% CI, 0.74–1.16). Both low-dose (OR = 0.86) and high-dose (OR = 0.80) aspirin intake showed prevention effect. In addition, low frequency (OR, 0.87; 95% CI, 0.73–1.05) and high frequency (OR, 0.84; 95% CI, 0.69–1.03) seemed to be equally associated with decreased risk for PC. Aspirin consumption longer than 10 years use seems to have better effect (OR, 0.73; 95% CI, 0.51–1.04) than shorter aspirin use (OR, 0.94; 95% CI, 0.77–1.15).

Conclusions:
Our study indicated that aspirin use might be associated with decreased risk of PC, especially at high doses. But we still need to be cautious when interpreting the results.
Word and Nonword Reading Efficiency in Postlingually Deafened Adult Cochlear Implant Users
Authors: Tamati Terrin N. , Vasil Kara J. , Kronenberger William G. , Pisoni David B. , Moberly Aaron C. , Ray Christin 
Published: December 2020

Hypothesis:
This study tested the hypotheses that 1) experienced adult cochlear implants (CI) users demonstrate poorer reading efficiency relative to normal-hearing controls, 2) reading efficiency reflects basic, underlying neurocognitive skills, and 3) reading efficiency relates to speech recognition outcomes in CI users.

Background:
Weak phonological processing skills have been associated with poor speech recognition outcomes in postlingually deaf adult CI users. Phonological processing can be captured in nonauditory measures of reading efficiency, which may have wide use in patients with hearing loss. This study examined reading efficiency in adults CI users, and its relation to speech recognition outcomes.

Methods:
Forty-eight experienced, postlingually deaf adult CI users (ECIs) and 43 older age-matched peers with age-normal hearing (ONHs) completed the Test of Word Reading Efficiency (TOWRE-2), which measures word and nonword reading efficiency. Participants also completed a battery of nonauditory neurocognitive measures and auditory sentence recognition tasks.

Results:
ECIs and ONHs did not differ in word (ECIs: M = 78.2, SD = 11.4; ONHs: M = 83.3, SD = 10.2) or nonword reading efficiency (ECIs: M = 42.0, SD = 11.2; ONHs: M = 43.7, SD = 10.3). For ECIs, both scores were related to untimed word reading with moderate to strong effect sizes (r = 0.43–0.69), but demonstrated differing relations with other nonauditory neurocognitive measures with weak to moderate effect sizes (word: r = 0.11–0.44; nonword: r = (−)0.15 to (−)0.42). Word reading efficiency was moderately related to sentence recognition outcomes in ECIs (r = 0.36–0.40).

Conclusion:
Findings suggest that postlingually deaf adult CI users demonstrate neither impaired word nor nonword reading efficiency, and these measures reflect different underlying mechanisms involved in language processing. The relation between sentence recognition and word reading efficiency, a measure of lexical access speed, suggests that this measure may be useful for explaining outcome variability in adult CI users.
Cochlear Implantation and Electric Acoustic Stimulation in Children With TMPRSS3 Genetic Mutation
Authors: Holder Jourdan T. , Morrel William , Rivas Alejandro , Labadie Robert F. , Gifford René H. 
Published: December 2020

Background:
Mutations in the TMPRSS3 gene, although rare, can cause high frequency hearing loss with residual hearing at low frequencies. Several previous studies have reported cochlear implant (CI) outcomes for adults with TMPRSS3 mutation with mixed results. Although some studies have suggested that TMPRSS3 is expressed in spiral ganglion cells, it remains unclear if previously reported poor CI outcomes in this population were secondary to long durations of deafness or to the effects of the TMPRSS3 mutation. To date, no studies in the literature have reported CI outcomes for children with TMPRSS3 mutation treated with CI.

Objective:
The current case series aimed to describe outcomes for three children with sloping hearing loss caused by TMPRSS3 mutation who underwent bilateral CI.

Study Design:
Case series.

Setting:
Academic medical center.

Patients:
Three children (3–4 yr) with TMPRSS3 mutation and normal sloping to profound high frequency hearing loss.

Interventions:
CI and electric acoustic stimulation (EAS).

Main Outcome Measures:
Outcome measures were residual hearing thresholds, speech recognition scores, and electrode placement determined via intraoperative CT imaging.

Results:
All three children maintained residual acoustic hearing and received benefit from EAS. Mean change in low-frequency pure-tone average was 17 dB. Mean postoperative word and sentence recognition scores in the bilateral EAS condition were 80 and 75%, respectively.

Conclusions:
Results indicate that CI with EAS is an appropriate treatment for children with TMPRSS3 genetic mutation. Pediatric results from this case series show more favorable CI outcomes than are currently reported for adults with TMPRSS3 mutation suggesting that the intervention may be time sensitive.

Published: December 2020

Objective:
To measure the subjective visual vertical (SVV) in patients suffering from peripheral vestibular disorders versus controls, using a smartphone-based test designed to simulate the bucket test, in order to validate it as an available tool for the clinician.

Study design:
Prospective cohort study.

Setting:
Academic tertiary medical center.

Patients:
Forty-five adult patients were recruited to the study, 25 had vestibular disorders, and 20 did not (controls).

Intervention:
All patients underwent conventional bucket-SVV (b-SVV) and smartphone-based SVV (s-SVV) testing.

Main outcome measures:
Correlation and agreement of b-SVV and s-SVV scores in patients with peripheral vestibular disorders compared to controls.

Results:
SVV score in the vestibular disorders group was significantly higher compared to controls in both testing methods (p < 0.001 for b-SVV and p
= 0.01 for s-SVV, effect size d = 1.7 for both testing methods). Intragroup correlation was excellent within the study group. Spearman's rank correlation coefficient between b-SVV and s-SVV was 0.902 (p
= 0.01). Agreement measurements suggested a greater sensitivity for the b-SVV test, showing a mean difference of 1.088 degree (SD ± 1.77); directionality, however, was preserved.

Conclusion:
The smartphone-based test is a valid, simple, and efficient in-office screening tool for assisting in the diagnosis of vestibular disorders.
