Authors: Costa Reis Raíssa 
Published: April 2023

A violência obstétrica é uma prática constante nos atendimentos de saúde ofertados nas instituições brasileiras, fazendo-se cada vez mais necessárias as discussões sobre o tema que envolve qualquer ato que fira a dignidade da mulher no âmbito da sua saúde sexual e reprodutiva. Isto posto, realizamos uma pesquisa qualitativa-fenomenológica objetivando evidenciar a percepção das mulheres sobre atos vivenciados ao longo do atendimento recebido no seu ciclo gravídico-puerperal. Como resultados, constatamos que as participantes pontuam o sentimento de desconforto diante de violências de cunho físico, verbal e institucional, que vão de encontro às diretrizes de assistência dos órgãos reguladores da saúde.Palavras Chave: Violência Obstétrica.

Published: April 2023

Until now, three approaches to asset portfolio management have been used. The first approach is the classic one, based on the "Efficient Market Hypothesis" (EMH). The second and more modern approach is related to the "Fractal Market Hypothesis" (FMH). Modern economic practice is characterized by the presence of structurally unstable markets, included as nodes in the network of the world economy, which functions in real time. The structure of the available financial instruments is heterogeneous and non-Markovian processes arise in them. The third approach is the formation of a dynamic strategy of investment management of the asset portfolio. Due to the complex structure of the modern global financial market, the heterogeneous structure of available financial instruments and traders using different approaches and time horizons, forecasts, as a rule, require a large number of observations, work poorly at the edges of bifurcations, and do not have a computer model that could build forecasts in real time. In these structures, slow diffusion-type processes with a memory phenomenon occur, i.e., non-Markovian processes. Therefore, the formation of a dynamic strategy using modern methods of mathematical and computer modeling is very promising.
Real financial data is expressed in rational numbers. Computational models were developed on the basis of classical substance analysis. Therefore, p-adic analysis methods are increasingly used in financial mathematical modeling. These methods are used, in particular, in the construction of neural networks, cellular automata, and percolation models. The paper seems to have taken the first step towards building a "synthetic" model of dynamic asset portfolio management. The model has the form of a differential equation in fractional derivatives obtained using the so-called interbasin kinetics method. A general form of the energy market model is also offered, as one of the specific, especially nowadays, markets.
SIMULATION OF INTERMEDIATE VISCOELASTIC SUPPORT UNDER NON-STATIONARY VIBRATIONS OF TIMOSHENKO BEAMS
Authors: Voropay Alexey , Povaliaiev Serhii 
Published: April 2023

When modeling mechanical objects and their systems, mathematical models developed for an elastic domain are most often used, which in some cases can lead to significant inaccuracies in calculations. The use of mathematical models that take into account visco-elastic properties or energy dissipation allows to obtain more realistic models, which will make it possible to obtain more accurate calculation results. In the paper non-stationary loading of a mechanical system, consisting of a beam hinged at the edges, and an additional support installed in the span of the beam is considered. We use a beam deformation model, which is based on the hypotheses of S. P. Timoshenko and takes into account the inertia of rotation and shear. The system of partial differential equations describing the deformation of the beam is solved by expanding the desired functions into the corresponding Fourier series and subsequent using the integral Laplace transform. The additional support is assumed to be realistic rather than absolutely rigid, having linear elastic and viscous components. It is assumed that at the point of attachment of the additional support to the beam their displacements coincide. The reaction between the beam and the additional support is replaced by an external unknown concentrated force applied to the beam, which changes with time. The law of change in time of this unknown reaction is determined from the solution of the Volterra integral equation. A method for obtaining an integral equation for an unknown reaction is described. Analytical relations and calculation results for specific numerical parameters are given. The influence of stiffness and viscosity on the determined reaction of the additional support, as well as on the deflections of the beam at various points, is investigated. The results obtained can also be used for damping forced vibrations of mechanical systems.

It is proposed to study the qualitative impact of electromagnetic fields on the membrane of plant tissue for preservation and delivery of them fresh to the final consumer. Spherical apple fruits were exposed to the influence of electromagnetic fields on the cell membrane. Ukraine is an industrial-agrarian country with a predominance of raw material production. It is one of the leading exporters of some types of agricultural products. The large number of fertile lands of our country indicates that Ukraine should be a full-fledged exporter of agricultural goods to the countries of Europe and the world. At the same time, two main problems arise: the production of quality agricultural products by farmers and their preservation for a long time in a fresh form. It is very important that the final consumer receives the product fresh and tasty.
The freshness of a product is preserved by freezing and keeping it at a temperature below minus 20 degrees Celsius. However, this method is not suitable when it comes to fresh fruit. Therefore, the object of research for a number of scientists was the influence of external electromagnetic fields on the process of preserving fruit and berry products. It was established that the membrane potential of the cell at the moment of physiological rest is important for the preservation of product freshness. It is at this moment that the metabolism is in balance. At the same time, the Krebs respiration cycle is used, which was discovered for animals, but was later proven in plants as well. The issue of researching the qualitative impact of electromagnetic fields on the membrane of plant tissue in order to preserve and deliver them fresh to the final consumer is very important and relevant. For example, it is possible to expose apple fruits, which have the shape of a sphere, to the influence of electromagnetic fields on the cell membrane.
The most important factor that affects the processes of growth and development of plants is known to be light, its direction, as well as its qualitative and quantitative characteristics. However, not everyone knows that there are two more environmental factors that have received little attention so far, and that are not always taken into account when analyzing the physiology of the plant organism. These factors are the electric field of the atmosphere, as well as the electromagnetic field of the Earth. At the same time, artificial external electromagnetic fields can affect fruits, both positively and negatively. The electrophysical characteristics of these fields determine the result of this influence. These are voltages, frequency, method of modulation, exposure, etc. The methods of storing of agricultural products are presented based on the presence in the fruit storage of electromagnetic field of ultra high frequency in the range 33,5–36 GHz, which blocks the ion channels and increases the fruit shelf life by up to seven times.

Published: April 2023

Background:
Patients with scoliosis secondary to cerebral palsy (CP) are often treated with posterior spinal fusion (PSF) with or without pelvic fixation. We sought to establish criteria to guide the decision of whether or not to perform fusion “short of the pelvis” in this population, and to assess differences in outcomes.

Methods:
Using 2 prospective databases, we analyzed 87 pediatric patients who underwent PSF short of the pelvis from 2008 to 2015 to treat CP-related scoliosis and who had ≥2 years of follow-up. Preoperative radiographic and clinical variables were analyzed for associations with unsatisfactory correction (defined as pelvic obliquity of ≥10°, distal implant dislodgement, and/or reoperation for increasing deformity at 2- or 5-year follow-up). Continuous variables were dichotomized using the Youden index, and a multivariable model of predictors of unsatisfactory correction was created using backward stepwise selection. Finally, radiographic, health-related quality-of-life, and clinical outcomes of patients with fusion short of the pelvis who had neither of the 2 factors associated with unsatisfactory outcomes were compared with those of 2 matched-control groups.

Results:
Deformity correction was unsatisfactory in 29 of 87 patients with fusion short of the pelvis. The final model included preoperative pelvic obliquity of ≥17° (odds ratio [OR], 6.8; 95% confidence interval [CI], 2.3 to 19.7; p < 0.01) and dependent sitting status (OR, 3.2; 95% CI, 1.1 to 9.9; p = 0.04) as predictors of unsatisfactory correction. The predicted probability of unsatisfactory correction increased from 10% when neither of these factors was present to a predicated probability of 27% to 44% when 1 was present and to 72% when both were present. Among matched patients with these factors who had fusion to the pelvis, there was no association with unsatisfactory correction. Patients with independent sitting status and pelvic obliquity of <17° who had fusion short of the pelvis had significantly lower blood loss and hospital length of stay, and better 2-year health-related quality-of-life scores compared with matched controls with fusion to the pelvis.

Conclusions:
In patients with scoliosis secondary to CP, pelvic obliquity of <17° and independent sitting status are associated with a low risk of unsatisfactory correction and better 2-year outcomes when fusion short of the pelvis is performed. These may be used as preoperative criteria to guide the decision of whether to perform fusion short of the pelvis in patients with CP.

Published: April 2023

Abstract
The bladed rotor is an important part in turbine machines. Timely detection of its blade rubbing fault may avoid serious accidents. This paper developed a rub-impact fault identification approach for the bladed rotor based on chaotic features such as average period, time delay, embedded dimension, and largest Lyapunov exponent. A dynamic analytical model of a rotating variable thickness blade with the rub-impact fault is established. It is verified that the blade rubbing model could obtain the relationship between the chaotic behaviors and the rub-impact fault for a rotating blade. Through the nonlinear characteristic analysis, we could establish that different blade rubbing states have a certain corresponding relationship with the chaotic characteristics, which provides the theoretical basis for the blade rubbing identification using the chaotic features. In particular, a rub-impact fault identification approach based on chaotic features is further studied. And the blade rubbing fault can be easily identified by combining four chaotic features, which is proven by experiments. Comparing with the time domain and frequency domain analysis methods, the proposed approach provides a new way to identify such blade rubbing fault.

Published: April 2023

Abstract

Objective: Results from studies investigating the association between maternal or child epilepsy, use of anticonvulsants in pregnancy, and childhood cancer are inconsistent and at times contradictory.
Methods: Linking Danish national databases, we obtained epilepsy and childhood cancer diagnoses, and anticonvulsant use data. We estimated adjusted odds ratios of all or specific childhood cancers in relation to maternal or child epilepsy and anticonvulsant therapies using conditional logistic regression.
Results: Maternal epilepsy was positively associated with all childhood cancers in offspring, specifically, with acute lymphoblastic leukemia (Odds Ratio (OR) = 1.68, 95% Confidence Interval (CI) = 1.16, 2.43) and Wilms tumor (OR = 2.13, 95%CI = 0.97, 4.68). When considering maternal ever (lifetime) ingestion of anticonvulsants, a positive association was found with all cancers (OR = 1.15, 95%CI = 1.01, 1.31), and central nervous system tumors (OR = 1.32, 95%CI = 1.03, 1.69) as well as neuroblastoma (OR = 2.05, 95%CI = 1.29, 3.28) among offspring. Maternal anticonvulsant use before or during the index pregnancy was related to CNS tumors in offspring (OR = 1.78, 95%CI = 0.99, 3.21), however the confidence interval included the null.
Significance: Maternal use of certain anticonvulsant medications may be a risk factor for cancer in offspring. Medical providers may need to consider what type of treatments to prescribe to pregnant mothers with epilepsy.
Single fluorogen imaging reveals spatial inhomogeneities within biomolecular condensates
Authors: Pappu Rohit , Wu Tingting , King Matthew , Farag Mina , Lew Matthew 
Published: April 2023

Abstract
Recent investigations have suggested that biomolecular condensates are viscoelastic materials. This implies that material properties of condensates are governed by internal microstructures. Furthermore, computations show that the internal organization in protein condensates is spatially inhomogeneous, featuring hub-and-spoke-like percolated networks of molecules. Here, we test these predictions using imaging of single fluorogenic dyes that are turned-on in response to specific chemical microenvironments. We deployed Nile blue (NB), Nile red (NR), and merocyanine 540 (MC540) for epifluorescence and single-molecule localization microscopy imaging of condensates formed by intrinsically disordered, low-complexity domains of proteins. Imaging with NB reveals internal environments that are uniformly hydrophobic, whereas NR shows preferential binding to hubs that are more hydrophobic than the surrounding background within condensates. Finally, imaging with MC540 suggests that interfaces of condensates are unique chemical environments. Overall, the high spatiotemporal resolution and environmental sensitivity of single-fluorogen imaging reveals spatially inhomogeneous organization of molecules within condensates.

Abstract

In clinical practice, many diagnosis tasks rely on the identification of cells in histopathology images. While supervised machine learning techniques require labels, providing manual cell annotations is time-consuming due to the large number of cells. In this paper, we propose a self-supervised framework (VOLTA) for cell representation learning in histopathology images using a novel technique that accounts for the cell's mutual relationship with its environment for improved cell representations. We subjected our model to extensive experiments on the data collected from multiple institutions around the world comprising of over 700,000 cells, four cancer types, and cell types ranging from three to six categories for each dataset. The results show that our model outperforms the state-of-the-art models in cell representation learning. To showcase the potential power of our proposed framework, we applied VOLTA to ovarian and endometrial cancers with very small sample sizes (10-20 samples) and demonstrated that our cell representations can be utilized to identify the known histotypes of ovarian cancer and provide novel insights that link histopathology and molecular subtypes of endometrial cancer. Unlike supervised deep learning models that require large sample sizes for training, we provide a framework that can empower new discoveries without any annotation data in situations where sample sizes are limited.

Abstract
The aim of this study was to evaluate dietary inclusion of calcium anacardate (CAN) associated or not with citric acid (CA) in late-phase laying hen diets on serum biochemical profile, serum lipid peroxidation (TBARS), enzymatic activity (CAT and SOD) of liver, ovary, magnum and uterus. A total of 432 laying hens with 63 weeks of age were distributed into nine treatments and six replicates. Treatments consisted of: T1 – diet without additives; T2 – diet with 0.25%CAN; T3 – diet with 0.25%CAN + 0.25%CA; T4 – diet with 0.50%CAN; T5 – diet with 0.50%CAN + 0.25%AC; T6 – diet with 0.50%CAN + 0.50%CA; T7 – diet with 0.75%CAN; T8 – diet with 0.75%CAN + 0.25%CA; T9 – diet with 0.75%CAN + 0.50%CA. Lower serum TBARS was observed in birds fed 0.75% CAN and associate with AC (0.50% CAN + 0.50% CA). Dietary inclusion of CAN (0.50% and 0.75%) or associated with CA (0.25% and 0.50%) resulted in lower CAT in the liver and higher enzyme activity in the magnum. SOD activity in magnum was higher in laying hens fed diet without additives and lower values was observed considering increasing level of CAN. Dietary inclusion of CAN (0.75%) and its association with CA (0.50% CAN with 0.50 CA) for late-phase laying hens reduce serum peroxidation. Higher CAT activity was observed in magnum from the level of 0.50% CAN with or without CA. Increasing levels of CAN associated with CA results in lower CAT activity in the liver and SOD activity in reproductive tissues.
