To compare single dose preoperative antibiotic versus five days antibiotic course in preventing surgical site infection for the pediatric inguinal herniotomy.

The present study was conducted on 100 patients of elective inguinal herniotomy from January 2019 to April 2020 and compared on the basis of single dose preoperative antibiotic versus five days antibiotic course. All the patients were evaluated on the 3rd, 7th and 28th post-operative period and instructions were given to the guardians about wound care and to attend for early follow up if any signs & symptoms of wound infection appear.

50% of the patients were treated with prophylactic single dose antibiotic, i.e. inj. Ceftriaxone (30 mg/kg/dose) at the time of induction only and rest 50% were treated with inj. Ceftriaxone(30mg/kg/dose) at the time of induction as well as postoperatively at night followed by four days of oral antibiotic with Syr/Tablet. Cephalexin (25mg/kg/day) three times daily for another 4 days.

Surgical Site Infection (SSI) in Group-B (4.0%) was higher than that of Group-A (2.0%) on day 3 but it was not significant (p=0.40). There was no significant difference in health status of the patients of the two groups when compared on post-operative day 7 and day 28 (p=0.99, p=0.99 respectively).

Implementation of single dose antibiotic prophylaxis regimes tailored to the prevalent organisms in the institution can result in enormous savings, as the study shows significant reduction in hospital stay with no significant increase in incidence of SSI.

La mayor parte de la evidencia sobre los impactos de las políticas para la promoción del desarrollo infantil se refiere a programas piloto implementados en circunstancias estrictamente controladas. Este estudio aporta evidencia novedosa sobre los efectos de un programa de visitas domiciliarias implementado a escala. El programa que estudiamos, Cuna Más en Perú, se inició de cero en 2012 y, en tan solo tres años, ya ofrecía visitas domiciliarias semanales a más de 67.000 niños en zonas rurales. La estrategia de identificación proviene de la asignación aleatoria de distritos a las condiciones de tratamiento y control. Mostramos que, después de aproximadamente dos años, los niños asignados aleatoriamente al tratamiento tienen puntajes de desarrollo infantil que son 0,10 desviaciones estándar más altos que los niños asignados al grupo de control. La relación beneficio-costo estimada de la intervención es de 5,4.

Published: October 2021

In the current study, amount of heat transfer to the passenger compartment through the floor, which is one of the cooling load components of the vehicle, under normal working conditions were examined. For detailed investigations, floor of the passenger compartment was sub-divided into 11 regions by considering the material properties and the thermal condition under the region. By referencing the test results and making some assumptions, mean temperatures of the regions under the floor were determined. And then the heat transfer from the bottom of the vehicle to the passenger compartment was calculated. At the end of study, mean temperatures, heat transfers and heat fluxes of the regions were examined and some improvement modifications advised for heat transfer and economy points of views.
Algorithm for Finding Feedback in a Problem with Constraints for One Class of Nonlinear Control Systems
Authors: Dmitriev Michail G. , Murzabekov Zainelkhriet N. , Mirzakhmedova Gulbanu A.
Published: October 2021

For a continuous nonlinear control system on a finite time interval with control constraints, where the right-hand side of the dynamics equations is linear in control and linearizable in the vicinity of the zero equilibrium position, we consider the construction of a feedback according to the Kalman algorithm. For this, the solution of an auxiliary optimal control problem with a quadratic functional is used by analogy with the SDRE approach.

Since this approach is used in the literature to find suboptimal synthesis in optimal control problems with a quadratic functional with formally linear systems, where all coefficient matrices in differential equations and criteria can contain state variables, then on a finite time interval it becomes necessary to solve a complicated matrix differential Riccati equations, with state-dependent coefficient matrices. This circumstance, due to the nonlinearity of the system, in comparison with the Kalman algorithm for linear-quadratic problems, significantly increases the number of calculations for obtaining the coefficients of the gain matrix in the feedback and for obtaining synthesis with a given accuracy. The proposed synthesis construction algorithm is constructed using the extension principle proposed by V. F. Krotov and developed by V. I. Gurman and allows not only to expand the scope of the SDRE approach to nonlinear control problems with control constraints in the form of closed inequalities, but also to propose a more efficient computational algorithm for finding the matrix of feedback gains in control problems on a finite interval. The article establishes the correctness of the application of the extension principle by introducing analogs of the Lagrange multipliers, depending on the state and time, and also derives a formula for the suboptimal value of the quality criterion. The presented theoretical results are illustrated by calculating suboptimal feedbacks in the problems of managing three-sector economic systems.
Comparison of Style Features for the Authorship Verification of Literary Texts
Authors: Lagutina Ksenia Vladimirovna
Published: October 2021

The article compares character-level, word-level, and rhythm features for the authorship verification of literary texts of the 19th-21st centuries. Text corpora contains fragments of novels, each fragment has a size of about 50 000 characters. There are 40 fragments for each author. 20 authors who wrote in English, Russian, French, and 8 Spanish-language authors are considered.

The authors of this paper use existing algorithms for calculation of low-level features, popular in the computer linguistics, and rhythm features, common for the literary texts. Low-level features include n-grams of words, frequencies of letters and punctuation marks, average word and sentence lengths, etc. Rhythm features are based on lexico-grammatical figures: anaphora, epiphora, symploce, aposiopesis, epanalepsis, anadiplosis, diacope, epizeuxis, chiasmus, polysyndeton, repetitive exclamatory and interrogative sentences. These features include the frequency of occurrence of particular rhythm figures per 100 sentences, the number of unique words in the aspects of rhythm, the percentage of nouns, adjectives, adverbs and verbs in the aspects of rhythm. Authorship verification is considered as a binary classification problem: whether the text belongs to a particular author or not. AdaBoost and a neural network with an LSTM layer are considered as classification algorithms. The experiments demonstrate the effectiveness of rhythm features in verification of particular authors, and superiority of feature types combinations over single feature types on average. The best value for precision, recall, and F-measure for the AdaBoost classifier exceeds 90% when all three types of features are combined.
Text Classification by Genre Based on Rhythm Features

Published: October 2021

The article is devoted to the analysis of the rhythm of texts of different genres: fiction novels, advertisements, scientific articles, reviews, tweets, and political articles. The authors identified lexico-grammatical figures in the texts: anaphora, epiphora, diacope, aposiopesis, etc., that are markers of the text rhythm. On their basis, statistical features were calculated that describe quantitatively and structurally these rhythm features.

The resulting text model was visualized for statistical analysis using boxplots and heat maps that showed differences in the rhythm of texts of different genres. The boxplots showed that almost all genres differ from each other in terms of the overall density of rhythm features. Heatmaps showed different rhythm patterns across genres. Further, the rhythm features were successfully used to classify texts into six genres. The classification was carried out in two ways: a binary classification for each genre in order to separate a particular genre from the rest genres, and a multi-class classification of the text corpus into six genres at once. Two text corpora in English and Russian were used for the experiments. Each corpus contains 100 fiction novels, scientific articles, advertisements and tweets, 50 reviews and political articles, i.e. a total of 500 texts. The high quality of the classification with neural networks showed that rhythm features are a good marker for most genres, especially fiction. The experiments were carried out using the ProseRhythmDetector software tool for Russian and English languages. Text corpora contains 300 texts for each language.

Relevance. When forcing tulips in the early spring period in conditions of protected soil, the effectiveness of fertilizers has not been sufficiently studied. Manufacturers and suppliers of planting material do not give clear recommendations on the timing and doses of the use of mineral fertilizers in the distillation process.Material and methods. The object of study was 6 varieties of tulips of the Dutch selection of the mid-early flowering period. In the experiment, a "9-degree distillation technology"was used. For mineral fertilizing of tulips, a solution of calcium nitrate – Ca(NO3)2 was used in concentrations of 0.1% and 0,2%. The repetition of the experience is fourfold. To assess the effect of fertilizing on the growth and development of tulips, the dynamics of changes in biomorphological indicators was studied: the height of the plants, the diameter of the flower, the mass of cut flowers, as well as the output of commercial products. Results. It was found that the use of calcium nitrate fertilization at a concentration of 0,2% at the early stages of plant development contributes to the formation of a larger cut in the studied varieties, characterized by a high strong stem exceeding the control by 3,83-43,8%, the formation of large peduncles with a diameter of 3,24-5,85 cm and an increase in the yield of marketable products reaching 98%. The profitability of this variant of applying calcium nitrate fertilizing is on average 42% for varieties.Results.

Increasingly harsh conditions for the useof materials in modern, and especially - promising technological processes, the need to ensure andimplement the safest conditions for humanity and the environment of modern industrial production,the importance and increasing role of economic factors – all these factors necessitate improvingknown and creating new materials, as well as technologies for their production and use. Furthereconomically justified, socially attractive and technologically safe use of nuclear technologies andoperation of modern complex technical facilities, which undoubtedly include nuclear power devices,further development of nuclear and in the future thermonuclear energy is impossible withoutmodernization.The article implements the method of electron beam heating of a mixture of yttrium andzirconium oxides for the synthesis of complex oxides. The initial mixture contained ingredients in anamount corresponding to the compound Y2Zr2O7. The mixture was heated in a tantalum containeralmost to the melting point of tantalum (2915 C). The high temperature of the process is provided bythe use of a system with a plasma electron emitter. The purpose of the vacuum high-temperature effect on the powder mixture was to implement conditions sufficient to initiate reactions for the synthesis ofcomplex oxides. The analysis of the obtained samples recorded after the initial high-temperaturetreatment a fluorite-type phase (Y, Zr) Ox with a lattice parameter of 5.2 Å and technologicalimpurities of tantalum oxide. After additional annealing in air at 1200 C for 7 hours, another phasewith a lattice parameter of 5.17 Å was recorded, as well as impurities of tantalum oxide. The testedsynthesis conditions lead to the formation of multi-element oxides with a structure of only fluorite,pyrochlore phase in the heat is not detected.

Published: October 2021

Background: Arsenic present in underground water affects the overall health. The therapeutic effects of Allium sativum was investigated for ameliorating the toxic effects of arsenic exposed ducks. Even though, heavy metals especially arsenic toxicity and ameliorative effects of Allium sativum has been largely studied, yet the histopathological cardiac lesion grading and its correlation with oxidative stress and biochemical parameters is scarce. This study is aimed at evaluating cardiotoxic lesions due to arsenic and ameliorative effects of Allium sativum in accordance with histopathological grading with respect to oxidative and biochemical parameters. Methods: In the present study, 105 birds were randomly distributed in 5 groups. GRP II was given arsenic @ 30 ppm whereas GRP III, IV, V were given Allium sativum @ 0.5 gm/ kg feed, 1 gm/kg feed and 2 gm/kg feed respectively along with arsenic to study the ameliorative effects. At the end of 42 days, 6 birds from each group were slaughtered after blood collection and the extend of arsenic toxicity with Allium sativum effects were studied as biochemical and oxidative parameters with histopathological grading of lesions. The extent of lesions was graded as mild (+), moderate (++) and severe (+++). Result: Grossly, heart revealed dilatation and thickening of ventricular wall in GRP II along with congestion in coronary vessels. In GRP V, grossly heart revealed no congestion and comparatively reduced enlargement. Whereas microscopically, myocardial and epicardial oedema, disruption of muscle fiber and hemorrhage was observed. Along with this, there was increase in cardiac biomarkers - Total serum creatinine kinase (CK), creatine kinase-MB (CK-MB) levels and tissue oxidative parameters (LPO), with decrease in GSH, CAT, total antioxidant and SOD levels in GRP II which was comparably restored in GRP V.

Background: This study investigated immunoreactive changes in Slit2 and Robo receptors in the retinal ganglion cell layer of a rodent model of acute glaucoma. Methods: Glaucoma model using Sprague-Dawley rats was made via weekly intracameral injections of hyaluronic acid. Intraocular pressure (IOP) was measured twice weekly for 4 weeks using a rebound tonometer in an experimental group of 10 rats and a control group of five rats for 4 weeks. The trimmed retinas were processed for anti-glial fibrillary acidic protein (GFAP), anti-Slit2 and anti-Robo1, anti-Robo2, anti-Robo3 and anti-Robo4 immunochemical analysis. Result: The IOPs in the experimental group were approximately four times higher than IOPs in the control group. The GFAP, Slit2 and Robo4 immunoreactivity in the experimental group was higher than the corresponding values in the control group. Our results indicate that Slit2 and Robo4 potentially contribute to the progression of high tension glaucoma, especially in inducing ischemic injury.

The high pressures on Pterocarpus erinaceus Poir. severely affect its natural stands in West Africa. The measures taken to reverse this trend are still inefficient due to plantlets production constraints. This study aims to understand the importance of growing substrates on seedlings growth in nursery. Composite soil samples were collected at 20 cm depth from 4 seed trees in 5 different sites in Togo (West Africa). Two batches were made for each site, one of which was sterilized by autoclave and the other has received no treatment. Three growing parameters (length of stem, number of buds and number of leaves) of the plantlets obtained from sterilized seeds were measured during 20 weeks in the nursery. Results show for each site a significantly better growing rate of seedlings on unsterilized substrates, compared to sterilized substrates. At the end of the experiment, plantlets were 8.75 ± 2.32 cm mean height on sterilized substrates when they reach 19.20 ± 5.00 cm on unsterilized substrates. The mean number of buds and leaves per plantlet varies from 2.23 ± 1.71 buds and 3.00 ± 1.86 leaves to 10.73 ± 3.28 buds and 11.09 ± 2.48 leaves at the same date, respectively on sterilized and unsterilized substrates. The low growing rate on sterilized substrates should be linked to the low capacity of plantlets in mobilizing phosphorus, potassium and nitrogen without microorganisms. Negative impacts of sterilization were highlighted on seedlings by necrosis of buds and leaves from the 7th week of growth, demonstrating a positive effect of soil microorganisms on the proper development of the seedlings.

Published: October 2021

Entheseal spinal inflammation and new bone formation with progressive ankylosis may occur in ankylosing spondylitis (AS) and psoriatic arthritis (PsA). This study evaluated whether JAK inhibition with tofacitinib modulated the key disease associated cytokines, TNF and IL-17A and whether tofacitinib also modulated bone marrow stromal cell-derived mesenchymal stem cells (MSCs) function including osteogenesis, since post inflammation new bone formation occurs in these conditions. Methods: Conventional entheseal derived αβ CD4+ and CD8+ T-cells were in-vestigated following anti-CD3/CD28 bead stimulation to determine IL-17A and TNF levels in Tofacitinib treated (1000nM) peri-entheseal bone (PEB) and peripheral blood mononuclear cells (PBMC) following ELISA. Bone marrow stromal cell-derived mesenchymal stem cells (MSCs) colony forming unit (CFU-F) and multilineage potential was evaluated using tofacitinib (dosag-es ranging between 100, 500, 1000 and 10000nM). Results: Induced IL-17A and TNF cytokine production from both entheseal CD4+ T-cells and CD8+ T-cells were effectively inhibited by to-facitinib. Tofacitinib treatment did not impact on CFU-F potential or in vitro chondro- and oste-ogenesis. However, tofacitinib stimulation increased MSC adipogenic potential with greater Oil Red O stained area. Conclusion: Inducible IL-17A and TNF production by healthy human enthe-seal CD4+ and CD8+ T-cells was robustly inhibited in vitro by tofacitinib. However, tofacitinib did not impact on MSC osteogenesis but stimulated in vitro MSC adipogenesis, the rele-vance of which needs further evaluation given the adipocytes are associated with new bone formation in SpA.
Disproof of the Riemann Hypothesis
Authors: Vega Frank
Published: October 2021

We define the function $\upsilon(x) = \frac{3 \times \log x + 5}{8 \times \pi \times \sqrt{x} + 1.2 \times \log x + 2} + \frac{\log x}{\log (x + C \times \sqrt{x} \times \log \log \log x)} - 1$ for some positive constant $C$ independent of $x$. We prove that the Riemann hypothesis is false when there exists some number $y \geq 13.1$ such that for all $x \geq y$ the inequality $\upsilon(x) \leq 0$ is always satisfied. We know that the function $\upsilon(x)$ is monotonically decreasing for all sufficiently large numbers $x \geq 13.1$. Hence, it is enough to find a value of $y \geq 13.1$ such that $\upsilon(y) \leq 0$ since for all $x \geq y$ we would have that $\upsilon(x) \leq \upsilon(y) \leq 0$. Using the tool $\textit{gp}$ from the project PARI/GP, we found the first zero $y$ of the function $\upsilon(y)$ in $y \approx 8.2639316883312400623766461031726662911 \ E5565708$ for $C \geq 1$. In this way, we claim that the Riemann hypothesis could be false.

We investigate the power of time series analysis based on a variety of information-theoretic approaches from statistics (AIC, BIC) and machine learning (Minimum Message Length) - and we then compare their efficacy with traditional time series model and with hybrids involving deep learning. More specifically, we develop AIC, BIC and Minimum Message Length (MML) ARMA (autoregressive moving average) time series models - with this Bayesian information-theoretic MML ARMA modelling already being new work. We then study deep learning based algorithms in time series forecasting, using Long Short Term Memory (LSTM), and we then combine this with the ARMA modelling to produce a hybrid ARMA-LSTM prediction. Part of the purpose of the use of LSTM is to seek capture any hidden information in the residuals left from the traditional ARMA model. We show that MML not only outperforms earlier statistical approaches to ARMA modelling, but we further show that the hybrid MML ARMA-LSTM models outperform both ARMA models and LSTM models.
Assessment of the Contribution of a Thermodynamic and Mechanical Destabilization of Myosin–Binding Protein C Domain C2 to the Pathomechanism of Hypertrophic Cardiomyopathy–causing Double Mutation MYBPC3Δ25bp/D389V

Cardiac myosin-binding protein C (MyBPC) is a thick-filament associated regulatory protein in the sarcomere. It regulates the sensitive contractile system of the myocardium by acting as a mechanical tether, sensitizing the thin filament or modulating myosin motor activity. Mutations in the MYBPC3 gene are a frequent cause for the development of hypertrophic cardiomyopathy, the most frequent cardiac disorder. Recently, the monoallelic double mutation MYBPC3Δ25bp/D389V has been discovered as a subset of the common MYBPC3Δ25bp variant in South Asia. MYBPC3Δ25bp/D389V carriers exhibit hyperdynamic features, which are considered an early finding for the development of hypertrophic cardiomyopathy. Using correlation-guided molecular dynamics simulations sampling, we show that the D389V mutation shifts the conformational distribution of the C2 domain of MyBPC. We further applied biochemical approaches to probe the effects of the D389V mutation on structure, thermostability and protein-protein interactions of MyBPC C2. The melting temperature (Tm) of MyBPC C2 D389V is decreased by 4 to 7 °C compared to wild type while the interaction of the C0-C2 domains with myosin and actin remains unchanged. Additionally, we utilized steered molecular dynamics (SMD) simulations to investigate the altered unfolding pathway of MyBPC C2 D389V. Based on our data, we propose a pathomechanism for the development of HCM in MYBPC3Δ25bp and MYBPC3Δ25bp/D389V carriers.

Published: October 2021

Well placement optimization in a given geological setting for a fractured geothermal reservoir is a prerequisite for enhanced geothermal operations. High computational cost associated in the framework of fully coupled thermo-hydraulic-mechanical (THM) processes in a fractured reservoir simulation, makes the well positioning as a missing point in developing a field scale investigation. Here, in this study, we shed light on this topic through examining different injection-production well (doublet) position in a given real fracture network. Water and CO2 are used as working fluids for geothermal operations and importance of well positions are examined using coupled THM numerical simulations for both the fluids. Results of this study are examined through the thermal breakthrough time, mass flux and the energy extraction potential to assess the impact of well position in a two-dimensional reservoir framework. Almost ten times of the difference between the final amount of heat extraction is observed for different well position but with the same well spacing and geological characteristics. Furthermore, stress field is be a strong function of well position that is important with respect to the possibility of unwanted stress development. As part of the MEET project, this study recommends to perform similar well placement optimization study for each fracture set in a fully coupled THM manner before a field well drilling.

Published: October 2021

» Lumbar disc herniation is one of the most common spinal pathologies, often occurring at the L4-L5 and L5-S1 levels. The highest incidence has been reported in patients between the fourth and sixth decades of life.

» The severity of symptoms is influenced by the patient’s risk factors, the location, and the extent and type of disc herniation.

» Lumbar disc herniation can be effectively treated with multiple treatment protocols. In most cases, first-line treatment includes oral analgesic medication, activity modification, and physical therapy. When nonoperative treatments do not provide adequate relief, patients may elect to undergo a fluoroscopically guided contrast-enhanced epidural steroid injection. A subgroup of patients whose condition is refractory to any type of nonoperative modalities will proceed to surgery, most commonly an open or minimally invasive discectomy.

» The treatment algorithm for symptomatic lumbar disc herniation often is a stepwise approach: failure of initial nonoperative measures leads to more aggressive treatment when symptoms mandate and, as such, necessitates the use of a multidisciplinary team approach. The core team should consist of an interventional physiatrist, an orthopaedic surgeon, a physician assistant, and a physical therapist. Additional team members may include nurses, radiologists, neurologists, anesthesiologists, spine fellows, psychologists, and case managers.

» This review article describes a case scenario that uses a multidisciplinary team approach for the treatment of an acute L4-L5 disc herniation in a 31-year-old patient without any major comorbidities.

Departing from a condition in which the number of women involved in the warehouse sector industry is still low, even though culture in Indonesia does not hinder their involvement, there are opportunities to participate, and the existence or existence of women in this industry is not contradictory, so this study aims to determine how high the level of women's participation in the warehouse sector industry, as well as to find out what factors influence their involvement.
This study uses a quantitative approach with an explanatory and survey research format. Data was collected by distributing questionnaires to 70 respondents who were determined purposively. In addition, interviews were also conducted with several respondents as well as documentation and observation techniques. Data processing was carried out using percentage techniques and multiple linear regression techniques with the help of the SPSS (Statistical Program for the Social Science) program
The results of this study are as follows: 1) women's participation in the warehouse sector industry is still at a low level; 2) culture, existence and opportunities have an effect either partially or simultaneously on women's participation; 3) while the opportunity variable has the most significant effect on women's participation; 4) there are a small number of other variables that are not involved in this study which also influence women's participation in the warehouse sector industry.
