Joint linear array structure and waveform design for MIMO radar under practical constraints
Authors: Chu Chunhua , Chen Yijun , Zhang Qun , Luo Ying
Published: June 2022

Optimizing the array structure or emission waveform of a multiple-input multiple-output (MIMO) radar system is an effective method to improve the performance in practical applications. In this study, the joint optimization of array structure and the corresponding emission waveform under interference and noise conditions was investigated. When compared with the waveform or array structure optimization alone, this method allowed the MIMO radar system to obtain a higher degree of freedom. By considering the practical limitations of the MIMO radar system, a waveform with good properties, such as orthogonality or pulse compression performance, was selected as the reference waveform. Subsequently, based on the similarity constraint and constant modulus constraint, a bivariate joint optimization problem of array structure and waveform was formulated, and an iterative optimization algorithm was proposed to solve it. The array composition was determined using a combinatorial search algorithm while the emission waveform was obtained by solving the similarity model. Eventually, it effectively converged to form quasi-optimal match variables after limited iterations. The proposed method can be expanded to the optimal launch of a specific target and an environment with a proper or minimum number of antennas, as well as implement array optimization with the desired waveform. The simulation results prove the effectiveness of the proposed method. This method provides an ideal choice for real-time construction, flexible launch, and signal processing of MIMO radar systems.

Published: June 2022

The bivariate and multivariate probability distributions are useful in joint modeling of several random variables. The development of bivariate and multivariate distributions is relatively tedious as compared with the development of univariate distributions. In this paper we have proposed a new method of developing bivariate and multivariate families of distributions from the univariate marginals. The properties of the proposed families of distributions have been studies. These properties include marginal and conditional distributions; product, ratio and conditional moments; joint reliability function and dependence measures. Statistical inference about the proposed families of distributions has also been done. The proposed bivariate family of distributions has been studied for Weibull baseline distribution giving rise to a new bivariate Weibull distribution. The properties of the proposed bivariate Weibull distribution have been studied alongside maximum likelihood estimation of the unknown parameters. The proposed bivariate Weibull distribution has been used for modeling of real bivariate data sets and we have found that the proposed bivariate Weibull distribution has been a suitable choice for the modeling of data used.
Numerical approximation of a variable-order time fractional advection-reaction-diffusion model via shifted Gegenbauer polynomials
Authors: Chen Yumei , Zhang Jiajie , Pan Chao
Published: June 2022

The fractional advection-reaction-diffusion equation plays a key role in describing the processes of multiple species transported by a fluid. Different numerical methods have been proposed for the case of fixed-order derivatives, while there are no such methods for the generalization of variable-order cases. In this paper, a numerical treatment is given to solve a variable-order model with time fractional derivative defined in the Atangana-Baleanu-Caputo sense. By using shifted Gegenbauer cardinal function, this approach is based on the application of spectral collocation method and operator matrices. Then the desired problem is transformed into solving a nonlinear system, which can greatly simplifies the solution process. Numerical experiments are presented to illustrate the effectiveness and accuracy of the proposed method.
FMR1 is identified as an immune-related novel prognostic biomarker for renal clear cell carcinoma: A bioinformatics analysis of TAZ/YAP
Authors: Wu Sufang , He Hua , Huang Jingjing , Jiang Shiyao , Deng Xiyun , Huang Jun , Chen Yuanbing , Jiang Yiqun
Published: June 2022

WW domain-containing transcription regulator 1 (TAZ, or WWTR1) and Yes-associated protein 1 (YAP) are both important effectors of the Hippo pathway and exhibit different functions. However, few studies have explored their co-regulatory mechanisms in kidney renal clear cell carcinoma (KIRC). Here, we used bioinformatics approaches to evaluate the co-regulatory roles of TAZ/YAP and screen novel biomarkers in KIRC. GSE121689 and GSE146354 were downloaded from the GEO. The limma was applied to identify the differential expression genes (DEGs) and the Venn diagram was utilized to screen co-expressed DEGs. Co-expressed DEGs obtained the corresponding pathways through GO and KEGG analysis. The protein-protein interaction (PPI) network was constructed using STRING. The hub genes were selected applying MCODE and CytoHubba. GSEA was further applied to identify the hub gene-related signaling pathways. The expression, survival, receiver operating character (ROC), and immune infiltration of the hub genes were analyzed by HPA, UALCAN, GEPIA, pROC, and TIMER. A total of 51 DEGs were co-expressed in the two datasets. The KEGG results showed that the enriched pathways were concentrated in the TGF-β signaling pathway and endocytosis. In the PPI network, the hub genes (STAU2, AGO2, FMR1) were identified by the MCODE and CytoHubba. The GSEA results revealed that the hub genes were correlated with the signaling pathways of metabolism and immunomodulation. We found that STAU2 and FMR1 were weakly expressed in tumors and were negatively associated with the tumor stages. The overall survival (OS) and disease-free survival (DFS) rate of the high-expressed group of FMR1 was greater than that of the low-expressed group. The ROC result exhibited that FMR1 had certainly a predictive ability. The TIMER results indicated that FMR1 was positively correlated to immune cell infiltration. The abovementioned results indicated that TAZ/YAP was involved in the TGF-β signaling pathway and endocytosis. FMR1 possibly served as an immune-related novel prognostic gene in KIRC.

Published: June 2022

Outliers can cause significant errors in forecasting, and it is essential to reduce their impact without losing the information they store. Information loss naturally arises if observations are dropped from the dataset. Thus, two alternative procedures are considered here: the Fast Minimum Covariance Determinant and the Iteratively Reweighted Least Squares. The procedures are used to estimate factor models robust to outliers, and a comparison of the forecast abilities of the robust approaches is carried out on a large dataset widely used in economics. The dataset includes observations relative to the 2009 crisis and the COVID-19 pandemic, some of which can be considered outliers. The comparison is carried out at different sampling frequencies and horizons, in-sample and out-of-sample, on relevant variables such as GDP, Unemployment Rate, and Prices for both the US and the EU.
El movimiento martirial de Córdoba (850-859): causas y contexto histórico

Desde hace años, el tratamiento historiográfico del polémico tema de los mártires cordobeses del siglo IX ha sufrido un deslizamiento hacia la patología social que lo ha vuelto incomprensible al hacer de sus protagonistas individuos meramente desequilibrados, suicidas o incluso criminales. Es necesario recuperar la dimensión histórica del fenómeno, ahondando en sus causas religiosas y sociales, especialmente en la situación de la población cristiana bajo dominio musulmán, así como en el contexto político y cultural en que se produjo, que no es otro que el de la construcción de un Estado árabe e islámico por la dinastía Omeya y el de las resistencias muy extendidas y diversas que ello ocasionó.

Published: June 2022

This study aims at identifying the factors affecting successful recruitment strategies for individuals with autism spectrum disorder in the Jordanian companies listed on the Amman Stock Exchange (ASE). The analytical descriptive approach is followed in analyzing the study population, which included general managers of these companies as well as human resources managers in the companies in which this position exists. A total of 339 managers were selected in a comprehensive inclusion approach. The number of valid questionnaires is 300, with an estimated rate of 88.4%. The study concluded that there is a significant effect for both internal and external factors separately and collectively on the successful recruitment strategies and that the effect of internal factors on successful recruitment strategies is greater than the effect of external factors in the successful recruitment strategies of individuals on the autism spectrum. One of the most important recommendations of the study is to pay attention to both internal and external factors when adopting any recruitment strategies for individuals with autism spectrum. A national plan at the level of the Hashemite Kingdom of Jordan (HKJ) should be adopted taking into account the treatment of social incompetency, post-secondary education, and dealing wisely with the cases of common morbidity. The HKJ government must intervene to enact the necessary legislation and encourage the private and mixed sector enterprises to play their role in providing job opportunities for these individuals. In addition, there is a need for more studies on this sensitive topic in different work environments.

Authors: Piper Justin , Rodger James A.
Published: June 2022

We employ the concept of word sense disambiguation to determine the inherent meaning of voter intentions regarding possible political candidates from the 2016 Presidential election. We present our findings based on a website (www.presidentselect.com) that we developed, where candidates can be examined and their true assets and competencies in three major areas of eligibility, education, and experience inputs can be deciphered. Data envelope analysis is used to determine underlying word instances for elected and successful outputs. We also utilize our web site results to longitudinally extend these findings for decision making of potential election fraud detection in the 2020 Presidential election, utilizing Benford’s Law. Our results shed light on these phenomenon and provide new insights into the word sense disambiguation literature.

Published: June 2022

Introduction Phased distribution of the ChAdOx1nCoV-19 (Covisheild) vaccine was commenced in Sri Lanka in January 2021. Although the vaccine was well tolerated with a low reactogenicity profile in the clinical trials, there were safety concerns shortly after initiating vaccine rollouts in many countries.
Objectives This prospective observational study aimed to profile the adverse events following immunization (AEFI) amongst recipients of the ChAdOx1nCoV-19 between 30th January to 5th February at the University Hospital, KDU. The associations of AEFI were also evaluated.
Methods A cohort of 688 was followed up till the completion of vaccination. Data were collected using an interviewer-administered questionnaire and through telephone interviews. AEFI were classified according to WHO criteria. Results A total of 516(74.9%) participants experienced AEFI after the first dose, of which 377(73.0%) reported both systemic and local symptoms. By contrast, the incidence of AEFI were significantly lower after the second dose (n=134,21.1%, p<0.001). Fever being the commonest adverse event after the first dose (n=389,75.2%), injection site pain was frequent (n=85,63.43%) following the second dose. Of the four participants reported serious AEFI (0.6%) after the first dose, two had seizures. AEFI predominantly occurred within first 24 hours after each dose (77.1% and 67.9%, respectively) and lasted less than 72 hours in the majority (79.1% and 81.3%, respectively). The incidence of AEFI were significantly higher in females after the second dose (P=0.007).
Conclusions The reactogenicity to the ChAdOx1nCoV-19 vaccine amongst our population was lower than expected in clinical trials. The absence of life-threatening adverse events indicates a good safety profile of the vaccine.

Background: Long COVID syndrome (LCS) is a recognized sequel of SARS-CoV-2 infection. The aim of this study was to identify the respiratory symptoms of LCS and pulmonary function abnormalities in asymptomatic patients and those with mild to moderate disease, following their recovery from SARS-CoV-2 infection.
Methods: An observational study was conducted by recruiting COVID-19 patients presenting for follow-up at 3-months after discharge from intermediate care centre, Gampaha. Patients who had asymptomatic or mild-moderate COVID-19 were recruited by convenient sampling. Symptoms were assessed by an interviewer-administered questionnaire. Lung function was assessed by spirometry.
Results: There were 88 patients with a median age of 40 (28-51) years with female predominance (n=85, 96.6%). COVID-19 severity assessment revealed asymptomatic infection in 24 (27%), mild disease in 38 (40.9%) and moderate disease in 26 (31.8%) patients. Symptoms of LCS were present in 13 (54.2%) individuals who were asymptomatic and in 51 (79.7%) patients who had mild-moderate disease at the time of diagnosis. At least one respiratory symptom of LCS was seen in 64 (73%) patients at 3-months and the commonest was shortness of breath (SOB) (n=59, 67%). Majority of patients had mMRC grade 1 (n=39, 66.1%) or grade 2 (n=17, 28.8%) shortness of breath.
Presence of LCS was significantly associated with the disease severity (p=0.013) and presence of a comorbidity (p=0.016). Abnormal spirometry was noted in 67% and majority had a restrictive pattern (n=56, 64%). Abnormal spirometry findings were identified in 17 (71%) asymptomatic patients and 50 (78%) with mild-moderate disease.
Conclusions: Presence of respiratory symptoms of LCS is common following SARS-CoV-2 infection. SOB was the commonest manifestation and the frequency of respiratory symptoms was significantly higher in the presence of a comorbidity and increased disease severity. Abnormal spirometry were seen in a majority at 3 months following COVID-19.

Published: June 2022

There are conflicting data about level and duration of Abs to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children after symptomatic or asymptomatic infection. In this human population, we enrolled adults and children in a prospective 6-mo study in the following categories: 1) symptomatic, SARS-CoV-2 PCR+ (SP+; children, n = 8; adults, n = 16), 2) symptomatic, PCR−, or untested (children, n = 27), 3) asymptomatic exposed (children, n = 13), and 4) asymptomatic, no known exposure (children, n = 19). Neutralizing Abs (nAbs) and IgG Abs to SARS-CoV-2 Ags and spike protein variants were measured by multiplex serological assay. All SP+ children developed nAb, whereas 81% of SP+ adults developed nAb. Decline in the presence of nAb over 6 mo was not significant in symptomatic children (100 to 87.5%; p = 0.32) in contrast to adults (81.3 to 50.0%; p = 0.03). Among children with nAb (n = 22), nAb titers and change in titers over 6 mo were similar in symptomatic and asymptomatic children. In children and adults, nAb levels postinfection were 10-fold lower than those reported after SARS-CoV-2 mRNA vaccination. Levels of IgG Abs in children to SARS-CoV-2 Ags and spike protein variants were similar to those in adults. IgG levels to primary Ags decreased over time in children and adults, but levels to three spike variants decreased only in children. Children with asymptomatic or symptomatic SARS-CoV-2 infection develop nAbs that remain present longer than in adults but wane in titer over time and broad IgG Abs that also wane in level over time. However, nAb levels were lower postinfection than those reported after immunization.
Transforming Convivial Conservation
Authors: van Bommel Severine , Boonman-Berson Susan
Published: June 2022

Convivial conservation requires a deep structural shift in research methods and methodology. Although convivial conservation calls for moving beyond the dichotomy of the human and the non-human, this dichotomy is often reproduced in the research methods and methodologies that are used. Most (conservation) researchers have been trained to investigate what non-humans might ‘mean’ to humans, thereby inevitably silencing the voices of non-humans. This research article identifies a number of threshold concepts and methodologies by turning to multi-species work in nature conservation and challenges the historical anthropocentric framings in this field. It critically challenges the convivial conservation concept by questioning who or what is counted as a research participant from this perspective. Additionally, the article outlines different multi-species research methods and methodology and puts forward the need for threshold and promiscuous methods developed with collaboration between social and natural scientists and non-humans to bring about transformative change in conservation as envisaged by the proponents of convivial conservation. It concludes by offering ways to promote greater conviviality in nature conservation research through a more expansive sense of research participants, recognition of their inter-subjectivities, and multi-sensory communication of their situated knowledges.

Published: June 2022

Background:

Gracilis muscle has been used in reconstructive surgery for free muscle flap transfer. It was reported to be a reliable flap with lower rates of donor-site morbidity. In this study, we aimed to emphasize the anatomical variations of the obturator nerve.

Materials and Methods:

Clinical results of 14 patients who underwent lower lip reconstruction and facial reanimation with free gracilis muscle transfer between March 2017 and May 2021 were examined.

Results:

We identified eight male and six female patients, with a mean age of 55.6 years (range: 37–73 years). Of 14 patients, nine (64.3%) were operated on for lower lip reconstruction, and the remaining five cases underwent facial reanimation. Despite adequate dissection, we could not find the branch of the obturator nerve for gracilis muscle in two cases (14.3%), while vascular pedicles are detected in all cases. The first case was a lower lip reconstruction and the second case was a facial reanimation.

Conclusion:

While gracilis muscle is a good option for functional muscle transfer, it may be difficult to find the branch of the obturator nerve. Our study may suggest the need for consideration of anatomical variations of the obturator nerve before surgical planning for improved shared decision-making.
Chinese Idioms: Stepping Into L2 Student’s Shoes
Authors: Petrovčič Mateja
Published: June 2022

Idiomatic expressions play an important role in communication. They are widely used in both spoken and written discourse and are often one of the indicators of native-like proficiency. This paper discusses Chinese idioms chengyu in foreign language education, presents some observations regarding the scope of idioms predicted for the advanced level of Chinese, and introduces conceptual gaps between L1 and L2 as possible reasons for learners’ mistaken usages. This study argues that equipping students with skills and knowledge needed for reaching contextually appropriate use of idioms should be the main goal in the teaching/learning process and provides a set of practical suggestions as to which aspects of teaching idioms should be considered thoroughly.

Published: June 2022

Background: Bacterial vaginosis (BV) in pregnant women remains a cause for clinical concern among clinicians and health care professionals. BV  has been linked to prenatal, antenatal and postnatal challenges in pregnant women. Information on prevalence of BV across trimesters of  pregnancy is expected to give better clinical insight into the pathophysiology of this polymicrobial disorder. This study was conducted to determine  the prevalence of BV in pregnant women attending the Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria.

Methodology: This was a cross-sectional study of 120 pregnant women (40 in each trimester of pregnancy) who had symptoms suggestive of BV,  selected by systematic random sampling from among the women attending the Obstetrics and Gynaecology (O & G) clinic of NAUTH, Nnewi. Each  subject participant was examined by the attending clinician, and high vaginal swab (HVS) sample was collected for diagnostic analysis of BV using  with complete Amsel’s clinical criteria, which consists of three of the four criteria; (i) adherent and homogenous vaginal discharge, (ii) vaginal pH >  4.5, (iii) detection of clue cells on saline wet mount, and (iv) amine odor after the addition of potassium hydroxide (positive Whiff test).

Results: The mean age of the 120 selected participants was 27.25±6.09 years. The age groups 25-29 (36.7%) and 20-24 years (33.3%) constituted the  largest proportion, while age groups <20 (5.0%) and 40-45 years (5.0%) constituted the least. Of the 120 participants, 26 (21.7%) were positive for BV  by the Amsel’s criteria. Pregnant women in age group <20 years had the highest prevalence of BV (100%, 6/6), followed by those in the age groups  20-24 (27.5%), 40-45 (16.7%), 25-29 (15.9%), 30-34 (9.1%) and 35-39 years (0%) (X2=28.063, p=0.0001). Prevalence of BV was significantly higher in  single (unmarried) pregnant women (45.5%, X2=4.038, p=0.045), women with primary school education level (66.7%, X2=14.530, p=0.001),  unemployed women (36.1%, X2=13.278, p=0.0013), and nulliparous women [36.4%, X2 (for trend) = 4.805, p=0.0274), while there was no significant  difference in the prevalence of BV with relation to trimester of pregnancy (X2=2.750, p=0.253).

Conclusion: This study reveals a relatively high prevalence of BV and significant association with factors such as age group, education and  occupational status among pregnant women attending NAUTH Nnewi. Regular screening of women for BV prenatally may enable appropriate  interventions to prevent adverse pregnancy outcomes.

Published: June 2022

Background: Pulmonary aspergillosis (PA) is common among patients with tuberculosis (TB). With both infections presenting with similar clinical and radiologic features, diagnosis of PA is often made too late or missed completely due to lack of clinical suspicion and poor diagnostic laboratory  capacity for mycotic infections prevalent in our settings. We present a case of preventable mortality caused by delayed diagnosis and treatment of  PA in a patient with pulmonary TB (PTB).

Case presentation: A 13-year-old female was diagnosed and treated for PTB, having received anti-TB regimen for 8 months in a mission hospital  from where she was referred due to worsening cough, chest pain and progressive breathlessness. The patient was re-assessed and investigated,  with GeneXpert detecting Mycobacterium tuberculosis, susceptible to rifampicin. Diagnosis of pulmonary tuberculosis complicated by right  pneumothorax was made indicating an emergency thoracotomy and chest tube insertion and continuation of the first line anti-TB regimen. At about  2 weeks into admission, patients had features of superimposed acute bacterial sepsis with fever becoming high grade, marked neutrophilia  with toxic granulation and elevated sepsis biomarker, and this necessitated empiric antibiotic treatment with parenteral meropenem and  vancomycin. However, the patient only had mild clinical improvement following which there was progressively worsening respiratory symptoms and  massive haemoptysis. Result of sputum fungal study was available on admission day 20 and revealed a growth of Aspergillus flavus. Treatment with  intravenous voriconazole was however commenced rather late when the fungal respiratory disease could no longer be remedied. The patient died  on admission day 23.

Conclusion: Diagnosis of PA in patients with background TB is often made too late to guarantee timely and effective  antifungal treatment with negative consequences on patients’ outcomes. Improving clinical and laboratory capacities is essential to reducing  mortality from PA in healthcare facilities.

Published: June 2022

The objective of this study is to optimize reaction time, reaction temperature and their interactive effects on the oil yield of big seeded varieties of castor-oil plant, (Ricinus communis) seed using response surface methodology (RSM). Thirteen (13) experiments with different combinations of reaction time ( ) and reaction temperature ( ) ranging from 1hr (60mins) to 10hrs (600mins) and 60oC to 100oC respectively were performed. A quadratic polynomial model was obtained to predict the percentage oil yield for the big seeded varieties of castor seed. Our result show that the optimal conditions for the oil yield within the experimental range of the variables studied were 8.68hrs (520.92mins) and 94.14oC respectively. These values of the optimum process conditions were then fitted into the quadratic polynomial model to predict the optimum value of big seeded varieties of castor seed oil yield found to be 55.76%.  The model has a p-value less than 0.05 having a coefficient of determination R2 value of 0.9530 indicating that the model explained 95.30% of variation in the original data. The result also presented an adjusted R2 value of 91.95% and predicted R2 value of 66.59% which suggest that the model could explain 67% of variation in predicting novel observations. The optimization process employed in this study, clearly aid us to know the percentage yield of oil that could be extracted from big seeded varieties of castor seed and the optimum yield value possible at a certain reaction time and reaction temperature.

Published: June 2022

Plantain peels and palm oil mill slurry are discarded as waste from the processing industry in our locality, which accumulates and thereby constituting menace to the environment. The current rising cost of grains and concentrates used in the production of livestock feeds, has led to the alternative use of non-conventional feed stuffs such as ripe plantain peels and palm oil mill slurry, amongst others. The objective of this study was to formulate and develop a feed stock from locally derived non-conventional feed stuffs for animal feeds production code-named MUSARPOMS using appropriate standard technique. The major ingredient for MUSARPOMS is ripe plantain peels and palm oil mill slurry. The results revealed that MSP25% recorded highest crude protein (CP) value of 22.17 %, it was not significantly (P>0.05) different from the CP values (20.42 %) obtained from MSP50% but significantly (P<0.05) different from MSP75% value of 19.25 %. The crude fibre (CF) values were not significantly (P >0.05) different among the different grades. Ash and NFE values differ significantly amongst treatment. MSP75% recorded highest Ash and NFE value of 8.28 % and 515.60 % respectively. It was observed that the reducing levels of MUSARPOMS fermented mixture grade formulations, resulted in proportional increase in the crude protein of the emerging ingredients. 25% MUSARPOMS grade had a higher crude protein value of 22.17 % compare to 50% MUSARPOMS value of 20.42 and 75% MUSARPOMS value of 19.25 % and far above the 10.69 % of the plantain peels.

Loss of biodiversity has been recognized as one of the main threats to the forest ecosystem. This study examined the diversity and conservation status of woody species in the secondary forest of Obafemi Awolowo University, Ile-Ife, Nigeria using six permanent plots. All woody species were completely enumerated, and identified; their girths at breast height were measured at 1.3 m above buttress. Biodiversity status was assessed using Shannon-Wiener diversity, evenness of distribution, Sorrenson index of similarity and species importance value index. There were 77 tree species distributed into 62 genera and 30 families. The most abundant species were Celtis zenkeri and Lecaniodiscus cupanioides, while the most abundant families were Moraceae, Euphorbiaceae, and   Fabaceae. The tree species density ranged from 508 – 1132 plants per hectare. The Shannon-Weiner diversity index (1.83 to 3.50), evenness (0.483 – 0.741) and the basal area (6.06 – 25.73 m2 ha-1) were high in the forest. However, Celtis mildbraedii is critically endangered, while Garcina kola, Mallotus oppositifolus and Ricinodendron heudelotii are vulnerable. This study provides baseline diversity data for the conservation of woody species in the forest and concludes that this secondary forest is a potential biodiversity hub if properly managed. It will also play a key role in fashioning out realistic, appropriate, and effective conservation strategies that will enhance the restoration and management of the floristic composition of the secondary forest.

It has been tried to determine the ways in which schools are perceived in different areas for today, although it also includes the issues of the past. For schools; The scope was created by taking into account the prominent issues in the researches carried out in order to determine the opinions of students, parents and public opinion. The fact that they are on the hot agenda in certain periods seems to have been effective in the evaluation of schools from different perspectives. The number of academic studies on imam hatip schools in the field is quite high. Especially the research on its history has reached a certain extent. Studies in which the issues identified with these institutions, seen as problems or shown as a holistic approach are relatively few. In this study, it has been tried to determine the prominent issues about imam hatip schools, to include positive and negative evaluations, and to determine the situation in this way. In the studies, suggestions specific to these schools were also included rather than evaluations for general education. The ones that stand out from the variety of topics encountered as a result of the literature review and that are frequently repeated were preferred. Qualitative research method was used in the study, the data obtained by document analysis was evaluated by content analysis, and a descriptive approach was taken as basis.
UYGURCADA SÖZLÜK ÇALIŞMALARI
Authors: Orhun Murat
Published: June 2022

Sözlük çalışmaları dil araştırmalarında önemli konumda yer alır. Çünkü sözlük bir dilde kullanılan sözcüklerin toplamıdır. Zamanın ilerlemesi ile sözcüklerde de değişikler yaşanır. Yeni sözcükler üretilir ya da diğer dillerden kabul edilen sözcükler, daha önce kullanılan sözcüklerin yerini almaya başlayabilir. Politik nedenler, yaşadığı farklı bölgeler, dini inanç, sosyal ve kültürel etkiler nedeniyle aynı millet, kavim ya da topluma ait kişilerin kullandığı dilde, benzeri şeyler için farklı sözcükler kullanabilir. Bunlar dışında alfabe değişikliği, imla kuralları gibi nedenlerden daha önce kullanılan sözcükler değişime uğrayabilir. Günümüzde dil araştırmalarının gelişmesi, özellikle bilgisayar destekli yapay zekâ ile ilgili çalışmalarda sözcükler hiç olmadığı kadar çok etkili olmaktadır. Uygurlar dünyada yerleşik hayata erken dönemde geçen ve Türk kültür tarihine önemli katkılar sunan boylardan biridir. Bu katkılar içinde el sanatları, resim, minyatür, müzik gibi alanların dışında dil ve edebiyat ön plana çıkmaktadır. Çünkü Uygurlar günümüze kadar pek çok alfabe kullanmışlar, sayısız edebi eserler yaratmışlar ve Uygur Türkçesine ait sözlükler oluşturmuşlardır. Bu makalede günümüze kadar Uygurca ile ilgili yazılmış sözlükler araştırılmıştır ve sözlüklerin bir bibliyografyası oluşturulmuştur.

Actividad empresarial y rol promotor del estado en la constitución peruana de 1993
Authors: Gasco Valer María del Carmen
Published: June 2022

El artículo propone una interpretación constitucional del rol promotor del Estado y del principio de subsidiariedad en la Constitución de 1993, sobre la base de la noción de fomento, generalmente aceptada por la doctrina, como criterio para establecer cuándo puede el Estado desarrollar actividad empresarial en el marco de la Carta Magna vigente. El análisis se desarrolla desde el punto de vista del derecho público y utiliza para ello el enfoque horizontal1 del principio de subsidiariedad.

Video Based Human Activity Recognition Surveillance System
Authors: Juhi Singh  , Shweta Sinha
Published: June 2022

It is argued that current state-of-the-art methods of home surveillance such as motion detection
technology like CCTV intrusion alert are insufficient, in particular to cater the modern need of
whole automation with vulnerabilities such as requiring human involvement. We propose an
alternative system, a video-based Human Activity Recognition (HAR) approach using the
combination of Convolution Neural Network (CNN) and Long Short-Term Memory (LSTM)
algorithm, to dealwith the identified shortcomings. Our proposal does not require any changes
to the existing home security protocols and is easily implemented using only low-cost,
commercial-off-the-shelf hardware. We can easily use the traditional surveillance camera for
computer vision tasks. We evaluate our approach using real-world activity data collected via
video-based sensor. We quantify its effectiveness, by plotting Loss and accuracy curves. Our
results show that the video-based HAR approach can provide full automation in home
surveillancesystem compared to conventional CCTV motion detectors by an accuracy of more
than 93%. Further system’s accuracy can be increased and we can achieve significantly better
results by implementing LRCN (Long Term Recurrent Convolution Network) approach.
Model based investigations of the NVH behaviour of bogie brakes

Published: June 2022

"In the development of new train components, many development goals are in conflict with each other. For example, reducing the weight of the bogie and its components usually results in these components becoming more sensitive to vibrations. The bogie brake is a particularly critical component. The nonlinear frictional contact between the brake pad and the brake disc can lead to self-excited vibration phenomena caused by various excitation mechanisms that can result in NVH. These NVH phenomena can have a significant impact on component life and passenger comfort. To better assess the conflict between weight reduction and comfort or component lifetime due to NVH phenomena, simulations are often performed in addition to bench tests and field tests. By using appropriate simulation models and methods, problematic NVH phenomena can be addressed at an early stage of product development, which saves costs. Experience shows that the simulation models used often do not describe the dynamic problems accurately enough and certain NVH phenomena cannot be reproduced by simulation. Previous work has already shown that the model boundary conditions used usually represent the boundary conditions of test benches and do not consider the installation situation in the train. However, these boundary conditions have a considerable influence on the simulation results of unstable vibrations with complex eigenvalue analysis (CEA). For example, by selectively extending the system limits of the brake disc in the simulation, it was possible to show that the system becomes significantly more sensitive to self-excited vibrations. The models developed for CEA are now to be extended to include a speed-dependent friction value to investigate the nonlinear influence of a falling friction characteristic on the system dynamics of the bogie brake. In addition, the influence of different brake components and different operating conditions on the dynamic behaviour of the entire brake unit will be investigated The main objective is to demonstrate the influence generated by lightweight construction on the brake's dynamic stability behaviour.

Next evolutions in the devlopment of brake emission testing
Authors:   AVL List GmbH, Danner Christof
Published: June 2022

"The first approach towards a regulation of Brake Emissions by PMP (Particle Measurement Program) under the United Nations Economic Commission for Europe (UNECE) is ongoing – with a dedicated cycle, defined indicators to be measured and a procedure to be confirmed within a Round Robin end of 2021 (results / feedback will be available for the paper then). Next big steps shall then be the consideration of xEVs with their capability to recuperate (TF4) and thus reduce the use of the friction brake, which shall be included in the first draft of an upcoming legal regulation. This will subsequently increase the complexity of the measuring procedures as most likely a full vehicle simulation will be required including recuperation strategies. In the end all measures and vehicle systems that contribute to a reduction of Brake Emission shall be considered, which means a huge peak of development on this topic with a respective high demand on test bench capacity. Affected components will not only be software and functions, but also new brake system hardware like Electromechanical Brakes, that shall also reduce emissions by e.g., “true zero drag” or better controllability for brake blending. Adapted simulation will be introduced and optimized to enable respective measuring at the test rigs. As the availability of brake test rigs is limited the industry is requested to flexibly provide affordable testing solutions to cover this accumulation in testing. The test rigs themselves might evolve from inertia dynos to inertia simulation – increasing the degrees of freedom. After the actual focus on – also electrified – passenger cars and Light commercial vehicles up to 3,5 tons also trucks will be considered. The topic is quite new, activities are just ongoing and will influence development and legislation soon. "
Original article Strengthening the Rule of Law as a Guideline for Improving Legal Policy and Legislation in the Field of Resocialization of Convicts
Authors: Лапшин В.Е. , Свинин Е.В.
Published: June 2022

Resocialization of convicts is one of the most important social problems of the legal order and clearly illustrates the need for close attention not only to the formal legal, but also to social results of force of law. In modern conditions, legal regulation in the field of re-socialization cannot be considered effective – it requires a revision and change of approaches not only to legislation, but also to legal policy. The article presents some shortcomings of the existing practice and formulates proposals that can contribute to strengthening the rule of law in the area under consideration.
Original article Political and Legal Views of William of Ockham
Authors: Соколов Ю.В.
Published: June 2022

В статье рассматривается вклад английского философа-схоласта Уильяма Оккама в теорию государства и права. Уровень изученности трудов У. Оккама, в том числе в области права, в российской науке оценен автором как низкий. Проанализирован важнейший источник политико-правовых идей философа – «Dialogus», ранее недоступный для значительной части российских исследователей, так как написан на латыни. Выделены политико-правовые идеи У. Оккама: всеобщее благо как основа государства, ограничение власти императора, разделение полномочий между светской и духовной властью. Высказано мнение о том, что У. Оккам не претендовал на ограничение власти церкви, то есть не выступал с протестанских позиций, а стремился четко определить полномочия духовной и светской властей

The article examines the contribution of the English scholastic philosopher William of Ockham to the theory of state and law. The level of study of Ockham’s works, including in the field of law, in Russian science is estimated by the author as low. The author analyzes the most important source of Ockham’s political and legal ideas, “Dialogus”, previously inaccessible to a significant part of Russian Ockham scholars, since it is written in Latin. Ockham’s political and legal ideas are highlighted: the common good as the basis of the state, restriction of the power of the emperor, division of powers between secular and spiritual authorities. The author believes that Ockham did not claim to limit the power of the church, that is, he did not speak from Protestant positions, but sought to clearly define the powers of the spiritual and secular authorities.
Original article Legal Nature of the Status of the Person Controlling a Debtor
Authors: Кондратовская С.Н. , Мацола К.Н.
Published: June 2022

В статье рассматривается правовая природа статуса контролирующего должника лица, анализируются положения действующего законодательства о банкротстве и сложившаяся судебная практика. Отмечается, что наблюдается тенденция снижения стандартов доказывания и определения в качестве достаточного объема косвенных доказательств. Делается вывод, что сущность категории контролирующего должника лица включает в себя несколько характеристик: законодательно закрепленное определение, открытый перечень критериев отнесения лица к числу контролирующего, опровержимые презумпции, судейское усмотрение при установлении у ответчика статуса контролирующего должника в рамках рассмотрения конкретного дела

The article examines the legal nature of the status of a person controlling a debtor, analyzes provisions of the current legislation on bankruptcy and the established judicial practice. There is a trend to reduce the standards of proof and definition of a sufficient amount of indirect evidence. It is concluded that the essence of the category of the person controlling a debtor includes several characteristics, such as a legally fixed definition, open list of criteria for classifying a person as controlling, refutable presumptions, judicial discretion when establishing the status of the person controlling a debtor in the framework of a particular case
