The intricate molecular environment of the native membrane profoundly influences every aspect of membrane protein (MP) biology. Despite this, the most prevalent method of studying MPs uses detergent-like molecules that disrupt and remove this vital local membrane context impeding our ability to quantitatively decipher the local molecular context. Using a library of membrane-active polymers we have developed a platform for the high-throughput analysis of the membrane proteome enabling near-complete spatially-resolved extraction of target MPs directly from their endogenous membranes into native nanodiscs that maintain the local membrane context. We accompany this advancement with an open-access database that quantifies the polymer-specific extraction variability for 2065 unique mammalian MPs and provides the most optimized condition for each of them. Our method enables rapid and near-complete extraction and purification of target MPs directly from any endogenous organellar membrane at physiological expression levels. To further validate this platform, we took several independent MPs and demonstrated how our resource can enable rapid extraction and purification of target MPs from different organellar membranes with high efficiency and purity. Further, taking two synaptic vesicle MPs, we show how the database can be extended to capture multiprotein complexes between overexpressed MPs. We expect these publicly available resources to empower researchers across disciplines to efficiently capture membrane ‘nano-scoops’ containing a target MP and interface with structural, functional, and other bioanalytical approaches.

The article presents the most informative ultrasound (US) signs of unchanged, "reactive," lymphoproliferative and metastatic lymph nodes (LN). A literature analysis was conducted on the stratification of US-signs of malignancy of the LN, on the basis of which it was concluded that at present time there is no single classification of US-signs of pathological changes in the LN, existing classifications have been developed to assess the LN in some regions, include from 3 to 5 categories and are not used everywhere. Due to certain difficulties in interpreting the nature of the LN lesions associated with their localization, size, number, severity of response to the infectious process and presence of oncological history of the patient, it is justified to create a unified classification of US signs of the LN changes employing 6 categories that is similar to previously accepted classifications of radiation diagnostics TI-RADS, BI-RADS. For a wide discussion by experts, it is proposed a draft classification Node-RADS for stratification US-signs of surface LN.

Published: September 2024

Placentation abnormalities resulting from using assisted reproductive technologies (ART) is a pressing global obstetrical issue due to complications associated with the pathology: bleeding during pregnancy, postpartum hemorrhage, higher number of cesarean sections, perinatal and maternal morbidity and mortality. This pathology rate tends to increase also due to higher number of pregnancies achieved via in vitro fertilization (IVF). In this regard, we decided to find out the key risk factors for developing this pathology, identify new international data on placentation abnormalities, ART impact on this disease, since ART have been increasingly used to achieve pregnancy in women, both in Russia and abroad. Recent studies have proven the unique morphological structure of the placental hematopoietic barrier in post-IVF women as well as an increased incidence of placentation abnormalities, placenta accreta and premature abruption in comparison with spontaneous pregnancy.

Published: September 2024

Aim: to compare changes in the ADAMTS-13 metalloproteinase/von Willebrand factor (vWF) axis in pregnant women with spontaneous or following in vitro fertilization (IVF) singleton and bichorial biamniotic pregnancies.

Materials and Methods. A prospective observational randomized controlled trial was conducted. The examination data of pregnant women with singleton (group 1, n = 34) and multiple bichorial biamniotic spontaneous pregnancies (group 2, n = 17), and with singleton (group 3, n = 34) and multiple bichorial biamniotic pregnancies (group 4, n = 34) following reproductive technologies were analyzed. The studied parameters included quantitation of ADAMTS-13 antigen (ADAMTS-13:Ag), ADAMTS-13 activity (ADAMTS-13:Ac) and vWF antigen (vWF: Ag) by chromogenic enzyme immunoassay.

Results. A progressive increase in the vWF:Ag level has been revealed that was proportional to escalating gestational age and a decrease in ADAMTS-13:Ag level from the second trimester of physiological non-induced pregnancy, more profound during twin pregnancy (p < 0.001). In induced pregnancy, vWF:Ag level increased, ADAMTS-13:Ag - decreased starting from 6-7 weeks of gestation (p < 0.001), more prominent in twin pregnancy (p < 0.001). The ADAMTS-13 activity in induced single and multiple pregnancies did not differ significantly by trimester but was lower compared with non-induced pregnancies of matched timeframe. The most pronounced decrease in the ADAMTS-13:Ag/vWF:Ag ratio was observed in multiple induced pregnancies.

Conclusion. Stimulation of superovulation and subsequent embryo transfer into the uterine cavity is accompanied by higher procoagulant vascular endothelium properties, vWF release, which activates platelets and the coagulation cascade from the early stages of induced pregnancy. vWF hyperreactivity is compensated by the expenditure of ADAMTS-13, which level declines dramatically during twin pregnancy creating conditions for disruption of hemostasis gestational adaptation and increases a risk of thrombotic complications and obstetric pathology.

Unlocking Hidden Risks: Harnessing Artificial Intelligence (AI) to Detect Subclinical Conditions from an Electrocardiogram (ECG)
Authors: Posan Emoke , Richie Rod
Published: September 2024

Recent artificial intelligence (AI) advancements in cardiovascular medicine offer potential enhancements in diagnosis, prediction, treatment, and outcomes. This article aims to provide a basic understanding of AI enabled ECG technology. Specific conditions and findings will be discussed, followed by reviewing associated terminology and methodology. In the appendix, definitions of AUC versus accuracy are explained. The application of deep learning models enables detecting diseases from normal electrocardiograms at accuracy not previously achieved by technology or human experts. Results with AI enabled ECG are encouraging as they considerably exceeded current screening models for specific conditions (i.e., atrial fibrillation, left ventricular dysfunction, aortic stenosis, and hypertrophic cardiomyopathy). This could potentially lead to a revitalization of the utilization of the ECG in the insurance domain. While we are embracing the findings with this rapidly evolving technology, but cautious optimism is still necessary at this point.

Published: September 2024

The 1693 Noto earthquake, which struck on 11 January, is one of the Italy’s largest and most devastating earthquakes. According to the Italian Parametric Earthquake Catalogue, it reached a maximum intensity of 11 on the Mercalli–Cancani–Sieberg scale and had an estimated magnitude of M 7.3. Nevertheless, its precise location and source definition remain subjects to debate due to the complexity of the seismic sequence and lack of geological evidence. A series of potential seismic sources differing in location, dimension, and kinematics have been proposed in the literature based on seismotectonic data and interpretations. The goal of this work is to perform a retrospective experiment to verify which of the proposed seismic sources have a better fit with the observed intensity data. To do so, novel simulation techniques are used to study this historical earthquake. We generated ground-motion scenarios for each proposed source model through a stochastic finite-fault simulation approach. Then, the simulated ground-motion parameters were converted to intensities using two different ground-motion intensity conversion equations for Italy. Finally, we compared these converted intensities with the observed intensity data in terms of normalized root mean square errors and converted intensities from ground-motion models. Our results generally show good consistency between converted intensities from the simulated and predicted ground motions, whereas the observed intensities fit better to converted ones from the peak ground velocity rather than peak ground acceleration. Our analysis reveals that the source model reproducing the best of the macroseismic data of the Noto earthquake is the Canicattì–Villasmundo fault system with a magnitude of 7.1.

Published: September 2024

A array of isocyanoalkenes, including aromatic, aliphatic, α,β-unsaturated, heterocyclic isocyanoalkenes, can be selectively synthesized via a copper catalyzed cross coupling - dehydration strategy. Utilizing this method, two natural products were prepared. The vinyl formamide as intermediate could be brominated, and then dehydrated to prepare a series of bromoisocyanoalkenes. The bromoisocyanoalkenes can undergo a [4+1] addition with NaSH to prepare thiazoles. This reaction was proceeded through a rare SNVπ displacement-cyclization pathway, producing an array of 4- or 5-substituted, or 4,5- disubstituted thiazoles. Additionally, an array of virtually unexplored isocyanoalkynes were prepared from bromoisocyanoalkenes. The chameleon-like isocyanoalkyne reacts with both nucleophiles and electrophiles and exhibits different reactivity under acidic or basic conditions.

Authors: Mishra Ranu Tiwari , Nayak Rashmi , Totade Sanjay
Published: September 2024

Background: Fine needle aspiration cytology (FNAC) is a safe, simple, non-invasive and inexpensive procedure for diagnosing the lesions of lymph nodes. It helps in the diagnosis of benign, infectious lesions as well as malignant lesions. It not only confirms or excludes metastasis in a case of a known primary malignancy but, also, helps to detect occult primary malignancy. Aim of the present study was to determine the frequency of malignant lesions of lymph nodes in FNAC.
Methods: Retrospective study included all cervical lymph node lesions reported on FNAC, in the department of pathology, NSCB Medical College, Jabalpur from January 2023 to June 2024 (18 months).
Results: Total cases of 414 lymph node aspiration were done, of which 78 cases (18.84%) were positive for malignancy. Among malignant lesion metastasis was the predominant lesion. Majority of cases were seen in 51-60 years age group with male predominance and male: female ratio was 6.1:1. The most common metastasis was from squamous cell carcinoma which was reported in 65 cases (84%), followed by 4 cases of adenocarcinoma and malignancy of epithelial origin each. One case each of metastasis from papillary carcinoma thyroid, anaplastic carcinoma thyroid and malignant melanoma was reported. In two cases cytological diagnosis of lymphoma (NHL) was made.
Conclusions: FNAC gives early and accurate results with minimal invasion and reduces the need for surgical biopsies, thus saves cost and time to reach the final diagnosis. It is concluded that FNAC is a useful tool in diagnosing malignant lesions of lymph nodes with a good certainty.
LTL-specification for development and verification of logical control programs in feedback systems
Authors: Neyzov Maxim V. , Kuzmin Egor V.
Published: September 2024

The article continues the series of publications on the development and verification of control programs based on LTL-specifications of a special type. Earlier, a declarative LTL-specification was proposed to describe the strictly deterministic behavior of programs, ways of its verification and translation were worked out: for verification, the model checking tool nuXmv is used, and the translation is carried out into an imperative programming language ST for programmable logic controllers.

When verifying the declarative LTL-specification of the behavior of programs, there may be a need to simulate the behavior of its environment. In general, it is required to ensure the possibility of constructing closed-loop systems “program-environment”. In this work, an LTL-specification of constraintly non\-de\-ter\-mi\-nis\-tic behavior of a Boolean variable is proposed to describe the behavior of the environment of logical control programs. This specification allows defining the behavior of Boolean feedback signals, as well as fairness conditions to exclude unrealistic scenarios of behavior.
The article proposes an approach to the development and verification of logical control programs, within which the behavior model of the program environment is described in the form of constraints on the behavior of its input signals, what allows avoiding a separate detailed representation of the processes of the environment operation. As a result, the obtained behavior model of the closed-loop system “program-environment” provides a number of advantages: simplification of the modeling process, reduction of the state space of the verified model, and reduction of verification time. If it is impossible to reduce the behavior of the environment to the behavior of existing input signals, this approach suggests using “imaginary” sensors — additional Boolean variables that are used as an auxiliary means for describing the behavior of input signals. The purpose of introducing imaginary sensors is to compensate for missing sensors to track the specific behavior of some elements of the environment that needs to be taken into account when defining realistic behavior of the inputs of a logical control program.
The proposed approach to the development and verification of programs taking into account the behavior of the environment (a control object) is demonstrated by the example of an industrial plastic molding plant.
Estimation of interpolation projectors using Legendre polynomials
Authors: Nevskii Mikhail V.
Published: September 2024

We give some estimates for the minimum projector norm under linear interpolation on a compact set in ${\mathbb R}^n$. Let $\Pi_1({\mathbb R}^n)$ be the space of polynomials in $n$ variables of degree at most $1$, $\Omega$ is a compactum in ${\mathbb R}^n$, $K={\rm conv}(\Omega)$. We will assume that ${\rm vol}(K)>0$. Let the points $x^{(j)}\in \Omega$, $1\leq j\leq n+1,$ be the vertices of an $n$-dimensional nondegenerate simplex. The interpolation projector $P:C(\Omega)\to \Pi_1({\mathbb R}^n)$ with the nodes $x^{(j)}$ is defined by the equations $Pf\left(x^{(j)}\right)=f\left(x^{(j)}\right)$. By $\|P\|_\Omega$ we mean the norm of $P$ as an operator from $C(\Omega)$ to $C(\Omega)$. By $\theta_n(\Omega)$ we denote the minimal norm $\|P\|_\Omega$ of all operators $P$ with nodes belonging to $\Omega$. By ${\rm simp}(E)$ we denote the maximal volume of the simplex with vertices in $E$. We establish the inequalities $\chi_n^{-1}\left(\frac{{\rm vol}(K)}{{\rm simp}(\Omega)}\right)\leq \theta_n(\Omega)\leq n+1.$ Here $\chi_n$ is the standardized Legendre polynomial of degree $n$. The lower estimate is proved using the obtained characterization of Legendre polynomials through the volumes of convex polyhedra. More specifically, we show that for every $\gamma\ge 1$ the volume of the set $\left\{x=(x_1,...,x_n)\in{\mathbb R}^n : \sum |x_j| +\left|1- \sum x_j\right|\le\gamma\right\}$ is equal to ${\chi_n(\gamma)}/{n!}$. In the case when $\Omega$ is an $n$-dimensional cube or an $n$-dimensional ball, the lower estimate gives the possibility to obtain the inequalities of the form $\theta_n(\Omega)\geqslant c\sqrt{n}$. Also we formulate some open questions.
Some polynomial subclasses of the Eulerian walk problem for a multiple graph
Authors: Smirnov Alexander V.
Published: September 2024

In this paper, we study undirected multiple graphs of any natural multiplicity $k>1$. There are edges of three types: ordinary edges, multiple edges and multi-edges. Each edge of the last two types is a union of $k$ linked edges, which connect 2 or $(k+1)$ vertices, correspondingly. The linked edges should be used simultaneously. If a vertex is incident to a multiple edge, it can be also incident to other multiple edges and it can be the common end of $k$ linked edges of some multi-edge. If a vertex is the common end of some multi-edge, it cannot be the common end of another multi-edge.

We study the problem of finding the Eulerian walk (the cycle or the trail) in a multiple graph, which generalizes the classical problem for an ordinary graph. The multiple Eulerian walk problem is NP-hard.
We prove the polynomiality of two subclasses of the multiple Eulerian walk problem and elaborate the polynomial algorithms. In the first subclass, we set a constraint on the ordinary edges reachability sets, which are the subsets of vertices joined by ordinary edges only. In the second subclass, we set a constraint on the quasi-vertices degrees in the graph with quasi-vertices. The structure of this ordinary graph reflects the structure of the multiple graph, and each quasi-vertex is determined by $k$ indices of the ordinary edges reachability sets, which are incident to some multi-edge.
Leader ‘leadership’ perceptions within a luxury hotel environment
Authors: Marinotti Greta , Johnston Alan
Published: September 2024

This study considers the role of leadership within the hospitality sector as a key tool in raising performance levels. Hospitality is unique in its service-based approach, which relies on employees to ensure effective service. Post-COVID-19 and Brexit, the hospitality sector has seen a shift in reliance towards a home workforce, and as such, retention has become an area of greater importance. This case study investigation adopted a qualitative approach to consider the perceptions of six managers within a UK-based luxury hotel. Semi-structured interviews were used to draw out their experience of approaches used to ensure effective delivery in their areas of responsibility. The research concludes that a shift in leadership approach (from autocratic to democratic) is a necessity to retain staff, particularly as the shift to a greater reliance on a home workforce due to COVID-19 and Brexit starts to impact the sector. There does, however, remain a need to be more autocratic in certain situations to ensure the quality of service. Subsequently, communication becomes critical in the building of relationships. The research considers leadership approaches from a managerial perspective and is based on individual perceptions. Traditionally, research has been conducted from an employee perspective.

Authors: Naderifar Vahideh , Sahran Shahnorbanun , Shukur Zarina
Published: September 2024

Information systems ease the collecting, processing, storing, and distributing informations, which in turn lead to decision-making and control in organizations. Information systems consist of information about key people, locations, and other important things in the organization. There is insufficient research on process mining, and the connection between data mining and model-driven process management. The goal of process mining is to discover, monitor, and improve processes by extracting knowledge from event logs. Conformance checking compares a process model with its event log. The inputs are event log and process model, while the output consists of diagnostic information, which shows differences and commonalities between the model and its log. The conformance checking technique is able to identify the similarities or differences between the process model and the event log. This research will introduce the conformance checking measures (fitness, precision, simplicity, and generalization) in order to improve the process model discovering from analytical aspects.

The sex particularities in cardiovascular responses to different stress stimuli in humans and rats were investigated using the physiological parameters, heart rate and blood pressure, and a new sensitive criterion of electrical heart and blood pressure variability, a normalized entropy. The result showed that cardiovascular reactivity depended on the type of stress and the sex of individual involved. The values of normalized entropy increased or decreased during and after stress. The changes in electrical heart and blood pressure variability were more pronounced and more prolonged when one compared with those in heart rate and blood pressure. Normalized entropy was demonstrated to be more sensitive criterion of sex and individual differences in cardiovascular responses is stressors than heart rate and blood pressure. So, resulis illustrate а perspective of new parameter using as а characteristic of electrical heart and blood pressure variability in male and female organism under stress conditions.

A novel electrochemically sensitive sensor has been developed based on Hydrochar derived from Phoenix dactylifera was prepared for the detection of Methylene Blue (MB). These hydrochar (HC) have been used for the modification of the glassy carbon electrode (GCE). This electrode was characterized by scanning electron microscopy (SEM). The electrochemical properties of MB in the modified electrode (HC/GCE) were studied by square-wave voltammetry (SWV) and cyclic voltammetry (CV) under optimized conditions. Owing to a synergistic effect, the HC/GCE exhibited an obvious electrocatalytic effect on positively charged MB. The influence of experimental variables (accumulation time, supporting electrolyte, pH) was studied. Under optimized conditions, the constructed sensor illustrated a linear voltammetric curve for the MB in the concentration interval from 10-4M to 10-10M, with a detection limit of 0.2nM. A study of the effect of interference on sensor functionality was carried out, as well as an analysis of MB recovery in real wastewater samples. The modified electrode offers numerous advantages, including easy preparation, low detection limit, high sensitivity, good repeatability, short response time and an effective detection platform for MB in wastewater.

Due to the great importance that activated carbon has gained through its use in combating pollution, removing dyes components, and other uses, it has been prepared in different ways. In this
research, a statistical study was conducted to compare the practical and theoretical values of activated carbon yield prepared from pomegranate peels with some additives (Novolak resin and Beji asphalt) in order to improve its specifications. Since the preparation of activated carbon is controlled by a group of variables, a number of matters were tested for the possibility of finding a linear relationship based on the effect of the amount of the iodine number, density, ash content, and humidity on the yield of all prepared types of activated carbon, and considering the possibility of achieving the relationship through additional additives that can be obtained through it on carbon with a homogeneous surface and specifications. Also, finding a general mathematical relationship that brings together all the types prepared from pomegranate peels after adding new variables representing the percentages of adding asphalt to them and novolak resin used in preparation and activation. This equation makes it possible to control the proportions of the resulting yield before trying to measure, test and evaluate any of the practically calculated values such as the iodine number, density, ash content and humidity using the mathematical equation and calculating them for unknown values if the other characteristics are known. This achieves a shortening of the time
period. The success of this method is evidenced by the high experimental R2 values, the low SE, and the logical variation of the variable coefficients.

A indústria de energia eólica no Brasil tem contribuído para a transição energética para uma matriz mais limpa no país. Essa expansão ocorre principalmente após incentivos ao setor de energias renováveis e à indústria a partir de 2002 e mais consistente após 2009 com o sistema de leilões. Porém, a produção de energia por fonte eólica no modelo centralizado acarreta diversos impactos, expondo populações a vulnerabilidades socioambientais. O estado do Rio Grande do Norte se destaca na produção de energia eólica no Brasil com a maior capacidade instalada e segunda maior quantidade de usinas. Assim, esta pesquisa objetiva analisar como os empreendimentos de energia eólica no RN têm planejado ações de prevenção e mitigação de impactos socioambientais. Para isso, foram analisados Relatórios e Estudos de Impactos Ambientais de empreendimentos para geração centralizada de energia eólica, consultando-se os Planos e Programas socioambientais. Foi observado um maior número de Planos/Programas na dimensão ambiental em detrimento da dimensão socioeconômica. Para grande parte dos impactos ambientais relatados por estudos de revisão de literatura, existem Planos/Programas correspondentes na maioria dos empreendimentos analisados, enquanto a grande maioria dos impactos socioeconômicos relatados pela literatura possuem Planos/Programas correspondente apenas na minoria de empreendimentos.
