The pseudo unicornuate uterus is a rare uterine malformation resulting from incomplete unilateral MÃ¼llerian aplasia and is estimated to occur in about 10-14% of all uterine anomalies. It is the consequence of a developmental arrest of one of Mullers ducts, which results in a normal hemi-uterus and a rudimentary horn with or without a cavity. We present a case that illustrates this pathology: This is Mrs. S. H, 30 years old, without any notable history, G2P2, G1: the first pregnancy was followed normally at the health center and the delivery took place by cesarian section for breech presentation in a primiparous woman at term, G2: The second pregnancy was followed up until 39 weeks of amenorrhea at the health center, admitted in early labor, obstetrical ultrasound revealed a single fetal pregnancy with breech presentation, the indication for extraction by the high route was indicated for breech presentation in a scarred uterus. On exploration we noted the presence of a right hemi-uterus in which the pregnancy had developed with a homolateral horn and adnexa, and a small rudimentary remnant on the left continuing with a tube.
Comparative Analysis of Two German Banks
Authors: Jere Thomas
Published: June 2021

This article explains results of a comparative to test the performance of two top banks in the German banking industry analysis using a financial ratio analysis method. The main determinants considered are solvency and liquidity indicators, which make it possible to observe the risk behaviour of banks before and after the financial crisis. The hypothesis of the study is that the behaviour of German banks depends on bank-specific variables that affect the institution ’s loan policy. The universal banks in Germany can be divided into three main types of institutions: commercial, public sector and cooperative banks. The analysis is carried out on banks of the same category in a decomposed manner.
Deutsche Bank and Commerzbank representing the commercial/Private sector.
Checking each Bank separately is carried out to detect the similarities or differences that each bank may have in terms of bank performance. The empirical analysis involves a sample of these German banks observed during 2015–2019.

Ethnic Features of the Settlement of the Yakuts in the Late XX and Early XXI Centuries
Authors: Bragina Dariia Grigorevna
Published: June 2021

As you know, the nature and use of space for the resettlement of ethnic groups is important for the study of ethnocultural identity and ethnicity in general. This article is devoted to the influence of the ethnic factor on the features of the settlement of the Yakuts, the indigenous population of the North-East of Siberia of the Russian Federation in extreme, sharply continental climate conditions. The author draws attention to the fact that the natural habitat acquires an ethnic orientation of survival in these conditions. It is now recognized that the indigenous people, like the Yakuts, have acquired high adaptive capabilities in extreme conditions for many generations. The bulk of the Yakuts live in the countryside of central Yakutia, and only a small part of the Yakut ethnic group lives in the northern ulus of the republic. On the territory of central Yakutia there are meadow «islands», the so-called alases (from the Yakut word «alaas») suitable for cattle breeding and horse breeding. Haymaking is the basis of the Yakuts' hay and pasture cattle breeding. Northern cattle breeding, with its haymaking as a traditional way of farming, is known to contribute to the formation of behavioral stereotypes of the Yakuts. Nevertheless, we note that in the modern conditions of globalization, industrial development of the North, value orientations are also changing, many traditional stereotypes of Yakut behavior are being overcome. The article draws attention to the traditional outlook of the Yakuts about the spiritual unity of man and nature, that the sustainable development of the Yakuts is largely related to the problem of the ecology of ethnic culture.

Anxiety and Anti-Inflammatory Agents
Authors: Ankali Kariyappa N. , Rangaswamy Javarappa , Shalavadi Mallappa , Naik Nagaraja
Published: June 2021

Background:

Iminostilbene and 1,2,3-triazole ring containing compounds are considered
as beneficial substrates in drug design.

Objectives:

This study was aimed at the synthesis of novel series of iminostilbene linked 1,2,3-
triazole pharmacophores (7c-n) by Cu(I) catalyzed 1,3 dipolar cycloaddition reaction between 5-
(Prop-2-yn-1-yl)-5H-dibenzo[b,f]azepine (7b) and various substituted azidobenzene derivatives (3cn).

Methods:

The chemical structures of compounds were confirmed by 1H NMR, 13C NMR, LC-MS
and molecular docking studies were carried out through HEX docking software.

Results:

The in vivo anti anxiety capacity of the compounds was evaluated by using “elevated plus
maze” (EPM), anxiety model. The results exhibited that compounds (7d, 7e, 7j and 7k) have a higher
anti anxiety effect close to diazepam. The anti-inflammatory activities of the synthesized compounds
were evaluated by “Carrageenan-induced rat paw edema” model, compounds (7b, 7c, 7d, 7f, and 7j)
demonstrated statistically significant inflammatory activity. Molecular docking analysis revealed that
compounds (7d, 7e and 7j) bound to GABA(A) proteins show more efficiency when compared to the
other analogues in the series.

Conclusion:

These results suggest that compounds (7b, 7c, 7d, 7e, 7f, and 7j) can be considered as
novel candidates for anti-anxiety and anti-inflammatory agents. Moreover, docking method was used
to elucidate anti-anxiety effect of compounds. This study furnished insight into the molecular interactions
of synthesized compounds with their physiological targets, and the potential to develop bioactive
heterocyclic compounds.

Preconcentration of Aluminum by Dual-cloud Point Extraction and its Determination by Inductively Coupled Plasma-optical Emission Spectrometry
Authors: Mortada Wael I. , Alharthi Sarah
Published: June 2021

Background:

The combination of cloud point extraction (CPE) with inductively coupled
plasma-optical emission spectrometry (ICP OES) is limited due to the effect of organic diluent and
surfactant on the signal.

Methods:

A dual-CPE process (d-CPE) was presented for the enrichment of aluminum (Al3+), before
determination by ICP OES, to exclude the effect of surfactant and organic solvent on the ICP
OES signal. The analyte was firstly extracted into Triton X-114 rich phase as a gallic acid complex.
In the second step, Al3+ was back extracted into an aqueous phase of HNO3 that was introduced into
ICP OES. The effects of pH, concentrations of gallic acid and Triton X-114, incubation temperature
and time, centrifugation conditions and the concomitant ions were evaluated.

Results:

The method displayed good analytical characteristics at the optimum conditions. An enrichment
factor of 49.5 was achieved. The linear calibration graph was obtained from 1.0 to 1000
μg L-1 and the detection limit was 0.31 μg L-1. The relative standard deviation was 2.3% (50 μg L-1
Al3+, n = 10). Quantitative recoveries ranging from 96.0 to 100% were obtained for spiked water
and geological samples. This procedure was used efficiently for preconcentration and quantification
of Al3+ in various samples by ICP OES.

Conclusion:

The presented procedure is simple, rapid, accurate, and safe. It can be used for the
determination of Al3+ by ICP OES in samples with complicated matrices.

Терагерцовое стимулированное излучение при оптическом резонансном возбуждении германия, легированного мелкими донорами
Authors: Жукавин Р.Х.
Published: June 2021

The mechanisms responsible for terahertz stimulated
radiation under resonant intracenter excitation of shallow donors
in bulk germanium are considered to be the inversion laser
mechanism (ILM) and electron stimulated Raman scattering
(e-SRS). The e-SRS cross-section was estimated in the case of
resonant excitation of odd levels of a shallow arsenic donor in
germanium. The output intensity under resonant excitation of
germanium doped with arsenic is calculated. It is shown that
at an intensity exceeding the threshold for e-SRS, there should be
a competition of mechanisms leading to a decrease in the intensity
of ILM, which can be detected by the dependence of the output
intensity on time.

The behavior of the electron spin relaxation time in bulk GaAs layers doped with Mn was studied experimentally. We investigated the dependence of the degree of circular polarization of photoluminescence in transverse and longitudinal magnetic fields. An increase in the relaxation time of the electron spin is found from 25 ns at low pumping power to 400 ns at the threshold pumping power.

A theoretical analysis of the degradation of the current-voltage characteristic and transient ionization processes occurring in a low-barrier uncooled GaAs Mott diode under the action of heavy ions of outer space and laser pulses simulating them is carried out. The response of the diode to the action of an arsenic ion with an energy of 200 MeV, corresponding to a linear energy transfer of 26 MeV∙cm2/mg, is compared with the response to the action of femtosecond pulses of optical radiation with a duration of 10 fs with a wavelength of 870 nm and 670 nm.

The role of the intervalley processes of electron-phonon interaction in the relaxation of excited shallow arsenic donors in germanium is analyzed. The rates of intracenter inter-valley transitions with emission of TA phonons in ger-manium are calculated in dependence on the uniaxial compression stress along {111} crystallographic direction. It is shown that inter-valley transitions to the ground state of the donor with emission of phonons can play a significant role in the relaxation of excited impurities only upon uniaxial stress of the crystal, since at zero stress, there are no exact resonances between impurity transitions and intervalley phonons. There are also transitions from highly excited states lying in a narrow band of energies (~ 0.5 meV) under very bottom of the conduction band to the first excited state 1s(3)(Г5) (in stressed germanium crystal to 1s(3)(Г3) state). The average rate of these transitions is estimated at 0.3×109 s-1.

Published: June 2021

Background

Social cohesion is associated with healthier behaviors and better health outcomes, and therefore may offer a mechanism for promoting better health. Low socioeconomic status (SES) communities face higher rates of chronic disease due to both community- and individual-level factors.

Objective

The aim of this study is to leverage social cohesion to promote healthier behaviors and prevent chronic disease in a low SES community. This protocol outlines the methodology for a pilot study to assess the feasibility of an intervention (Free Time For Wellness [FT4W]) using a social networking platform (Nextdoor) with mothers living in an urban, low-income community to improve social cohesion and promote healthy behaviors.

Methods

The study will involve three phases: (I) co-designing the intervention with mothers in the neighborhoods of interest, (II) implementing the intervention with community leaders through the social networking platform, and (III) evaluating the intervention’s feasibility. Phase I of the study will include qualitative data collection and analysis from in-depth, semistructured interviews and a co-design group session with mothers. Phases II and III of the study include a pre- and postintervention survey of participating mothers. Neighborhood-level data on social cohesion will also be collected to enable comparison of outcomes between neighborhoods with higher and lower baseline social cohesion.

Results

As of March 2021, recruitment and data collection for this study are complete. This protocol outlines our original study plan, although the final enrollment numbers and intervention implementation deviated from our initial planned methodology that is outlined in this protocol. These implementation learnings will be shared in subsequent publications of our study results.

Conclusions

Ultimately, this study aims to: (1) determine the barriers and facilitators to finding free time for wellness among a population of low-income mothers to inform the co-design process, and (2) implement and study the feasibility of an intervention that leverages social cohesion to promote physical activity in a community of low-income mothers. The results of this study will provide preliminary feasibility evidence to inform a larger effectiveness trial, and will further our understanding of how social cohesion might influence well-being.

Implementing Vertical Federated Learning Using Autoencoders: Practical Application, Generalizability, and Utility Study (Preprint)
Authors: Cha Dongchul , Sung MinDong , Park Yu-Rang
Published: June 2021

BACKGROUND

Machine learning (ML) is now widely deployed in our everyday lives. Building robust ML models requires a massive amount of data for training. Traditional ML algorithms require training data centralization, which raises privacy and data governance issues. Federated learning (FL) is an approach to overcome this issue. We focused on applying FL on vertically partitioned data, in which an individual’s record is scattered among different sites.

OBJECTIVE

The aim of this study was to perform FL on vertically partitioned data to achieve performance comparable to that of centralized models without exposing the raw data.

METHODS

We used three different datasets (Adult income, Schwannoma, and eICU datasets) and vertically divided each dataset into different pieces. Following the vertical division of data, overcomplete autoencoder-based model training was performed for each site. Following training, each site’s data were transformed into latent data, which were aggregated for training. A tabular neural network model with categorical embedding was used for training. A centrally based model was used as a baseline model, which was compared to that of FL in terms of accuracy and area under the receiver operating characteristic curve (AUROC).

RESULTS

The autoencoder-based network successfully transformed the original data into latent representations with no domain knowledge applied. These altered data were different from the original data in terms of the feature space and data distributions, indicating appropriate data security. The loss of performance was minimal when using an overcomplete autoencoder; accuracy loss was 1.2%, 8.89%, and 1.23%, and AUROC loss was 1.1%, 0%, and 1.12% in the Adult income, Schwannoma, and eICU dataset, respectively.

CONCLUSIONS

We proposed an autoencoder-based ML model for vertically incomplete data. Since our model is based on unsupervised learning, no domain-specific knowledge is required in individual sites. Under the circumstances where direct data sharing is not available, our approach may be a practical solution enabling both data protection and building a robust model.

Published: June 2021

BACKGROUND

Worldwide, efforts are being made to stop the COVID-19 pandemic caused by SARS-CoV-2. Contact tracing and quarantining are key in limiting SARS-CoV-2 transmission. Mathematical models have shown that the time between symptom onset and isolation of cases and isolation of contacts are the most important components that determine whether the pandemic can be controlled. Mobile contact tracing applications could accelerate the tracing and quarantining of contacts by automatically detecting and notifying contacts.

OBJECTIVE

This study aimed to assess the use of a national Dutch contact tracing app and its determinants among individuals diagnosed with SARS-CoV-2 infection.

METHODS

We used anonymized SARS-CoV-2 routine contact tracing data collected between October 28th 2020 and February 26th 2021 in the region of Amsterdam, the Netherlands. Complete case logistic regression analysis was performed to identify determinants of using the app. Continuous variables were modelled as B-splines due to their non-linear relationship.

RESULTS

Of 29,766 SARS-CoV-2 positive cases, 4,824 (16.2%) reported app use. Median age of the population was 41 (IQR 29-55) years and 46.7% were male. In multivariable analysis, males (aOR 1.11, 95%CI 1.04-1.18) and residents of municipalities surrounding Amsterdam were more likely to use the app (Aalsmeer aOR 1.34, 95%CI 1.13-1.58;Ouder-Amstel aOR 1.96, 95%CI 1.54-2.50), while those born outside the Netherlands, particularly those born in non-western countries (aOR 0.33, 95%CI 0.30-0.36), were less likely to use the app. Odds of app use increased with age until age 58 and decreased sharply thereafter (P<.001). Odds of app use increased with number of contacts, peaked at 8 contacts, and then decreased (P<.001). Individuals working in day-care, home-care and elderly nursing homes were less likely to use the app.

CONCLUSIONS

Contact tracing app use is low in the region of Amsterdam. To increase the impact of the app on SARS-CoV-2 control, attempts should be made to increase app use in general and especially among younger people, those born outside the Netherlands, and people with many contacts. Furthermore the app could be made more attractive by adding extra features like test result, local risk or vaccination status.

Freshwater ornamental fish such as carp, koi, and betta fish is a kind of a very potential happy developed in the Tulungagung district. The total production in the last 3 years is still above the average production of other freshwater ornamental fish. This study aims to know the best influence on the production of freshwater ornamental fish by the influence of capital, cultivation pond, manpower, and technology. The method of research used is by the purposive sampling method of predetermined culture. Furthermore, the data that has been in can be inserted into SPSS 18 which is in multiple linear regression. The results of this research show that on the cultivation of goldfish, the production factor has a significant effect on the production and the technology variable has the highest beta coefficient of 0.364. For the cultivation of Koi fish, the production factor does not have a significant influence on the production, and the technology variable has the highest beta coefficient of 0.462. For betta fish farming, production factors have no significant effect on production variable and capital variables have the highest beta coefficient of 0.353 which means that production variables are heavily influenced by modal variables. Based on the results of the research can be concluded that out of all production factors, technology has the most influential likelihood on the marketing of freshwater ornamental fish.

Catfish farming is growing rapidly because the cultivation and marketing technology is relatively easy for the community to master, and the required business capital is relatively small. Pond water waste originating from fish metabolism and dissolved food waste is toxic to fish. One of the efforts that can be done is fish farming that is integrated with plants through an aquaponics system. Research to determine the effect of AB Mix addition on the growth of African catfish and lettuce cultivated by the aquaponics system. The research method used was an experimental method with a completely randomized design (CRD) consisting of three treatments and three replications. The addition of AB mixed nutrition did not differ in the growing significance of catfish and lettuce. However, the increase in growth occurred with an increasing dosage of AB mix with the best treatment with AB Mix 3 mL L-1. This treatment resulted in absolute growth in fish of 20.52 g and 4.62 g of watercress. The use of a dosage of AB mix higher than 3 mL L-1 may result in better growth.

Published: June 2021

Viral nervous necrosis (VNN) is a disease that often infects groupers. It has caused mass death in more than 34 species of marine fish. DNA vaccination might become a solution againts the infection. The construction of the pmBA-CP DNA vaccine consisting of the beta-actin promoter of medaka fish (Oryzias latipes) and capsid protein (CP) encoding VNN RNA2 has been made in previous studies. This study aimed to test the efficacy of the pmBA-CP DNA vaccine for VNN. The experiment consisted of two stages, namely (1) detection of anti-VNN antibody induction in vaccinated fish using ELISA, and (2) challenge test for fish vaccinated with the VNN virus. Grouper (body length 8 cm to 10 cm) were divided into two groups with a density of 5 fish 60 L–1. The fish in the first group were vaccinated with pmBA-CP intramuscularly at a dose of 12.5 µg per fish, while the second group of fish were not vaccinated. Antibody titer testing was carried out before treatment, and 1 d, 7 d, 14 d, 21 d, 28 d, and 35 d after vaccination. The challenge test was carried out on the 60th day after vaccination. The results showed that the S / P ratio in the vaccinated fish serum was higher than unvaccinated fish at 21 d to 35 d post-vaccination. DNA vaccination was able to induce anti-VNN antibodies of grouper. The results of the challenge test for vaccinated fish using VNN virus titer 103.5 FID50/0.2 mL showed 60% of survival rate. Thus, the pmBA-CP DNA vaccine could be useful for increasing grouper immunity, and support production of grouper.

Authors: Larbi Ayisi Christian
Published: June 2021

In this study, the effects of using vegetable oils solely in finfish feed on nutritional status as well as lipid damage were evaluated. Polyene index (PI), atherogenic index (AI) as well as hypocholesterolemic and hypercholesterolemic fatty acids were assessed. Also, n-3/n-6 and n-6/n-3 ratios were assessed. In all, 32 articles were used for this study after carefully assessing them. Eighteen (18) articles had studied Freshwater species (FWF) whiles fourteen (14) had studied Marine species (MF). TI, n-3/n-6, and n-6/n-3 were significantly higher in fish-fed saturated fatty acids (SFA), n-3, and n-6 dominant vegetables. We document that using vegetable oils without supplementing fish diets with fish oil does not compromise the nutritional status as well as lipid damage. This work provides important information about the effect of using 100% vegetable oils in fish with respect to the nutritional composition of the final product.
