The paper analyzes the problem of entropy in the moments of transition from a normal economic situation (2015-2019) to the Pandemic period (2020-2021) and the period of Russia's attack on Ukraine (2022-2023). The research in the article is based on the analysis of electricity, oil, coal, and gas prices in 27 countries of the European Union and Norway. The daily data cover the period from January 1, 2015, to March 30, 2023, and were analyzed using two-dimensional sets of electricity and commodity prices.

We introduce a novel neuromorphic network architecture based on a lattice of exciton-polariton condensates, intricately interconnected and energized through nonresonant optical pumping. The network employs a binary framework, where each neuron, facilitated by the spatial coherence of pairwise coupled condensates, performs binary operations. This coherence, emerging from the ballistic propagation of polaritons, ensures efficient, network-wide communication.

Introduction: Liquid biopsies have great potential for precision medicine as they provide information about primary and metastatic tumors using minimally invasive techniques. MicroRNAs (miRNAs) are promising biomarkers for detecting gastric cancer (GC). The aim of the study was to identify miR molecules associated with autophagy in gastric cancer (GC) cells, determine their expression levels in GC and FLOT-treated patients, and assess the efficacy of FLOT therapy in GC patients.

The crystal structure determines the properties of compounds and materials, although one can find simple yet industrially relevant compounds such as potassium acetate (KOAc) and its hydrates for which the properties and even the composition still remain misunderstood, owing to the lack of structural data. In this study, the crystal structures of KOAc polymorphs and hydrates were determined for the first time. The water content in the crystal hydrates was reliably determined revealing two new phases 3KOAc·2HO and KOAc·HO ( = 0.

Parkinson's disease (PD), a neurodegenerative disorder without cure, is characterized by the pathological aggregation of α-synuclein (α-Syn) in Lewy bodies. Classic deposition pathway and condensation pathway contribute to α-Syn aggregation, and liquid-liquid phase separation is the driving force for condensate formation, which subsequently undergo liquid-solid phase separation to form toxic fibrils. Traditional Chinese Medicine (TCM) has a long history in treating neurodegenerative disease, herein; we identified chemicals from herbs that inhibit α-Syn aggregation.

Introduction: Folate receptors (FR) have been considered a convenient target for different radiopharmaceuticals in recent years. Multifarious Ga-labeled folate conjugates have been proposed as promising agents for the PET imaging of FR-overexpressing malignant neoplasms. In addition, radiolabeled folate-based conjugates can be effective for imaging non-tumor pathological foci characterized by a pronounced cluster of activated macrophages.

Liquid crystals (LC) are widely used in various optical devices due to their birefringence, dielectric anisotropy, and responsive behavior to external fields. Enhancing the properties of existing LCs through doping with nanoparticles, including semiconductor quantum dots, offers a promising route for improving their performance. Among various nanoparticles, QDs stand out for their high charge mobility, sensitivity in the near-infrared spectral region, and cost-effectiveness.

Growth of lithium whiskers or dendrites is the major obstacle towards safe and stable utilization of lithium metal anodes in rechargeable batteries. In this study, we look deeper into the mechanism of lithium electrodeposition. We find that before lithium whisker or dendrite nucleation occurs, lithium is deposited into the grain boundaries of the metal electrode, which we directly observed in the focused ion beam cross-sections of the lithium electrode.

We consider the effect of the emergence of chimera states in a system of coexisting stationary and flying-through in potential particles with an internal degree of freedom determined by the phase. All particles tend to an equilibrium state with a small number of potential wells, which leads to the emergence of a stationary chimera. An increase in the number of potential wells leads to the emergence of particles flying-through along the medium, the phases of which form a moving chimera.

Recent advancements in genomics, propelled by artificial intelligence, have unlocked unprecedented capabilities in interpreting genomic sequences, mitigating the need for exhaustive experimental analysis of complex, intertwined molecular processes inherent in DNA function. A significant challenge, however, resides in accurately decoding genomic sequences, which inherently involves comprehending rich contextual information dispersed across thousands of nucleotides. To address this need, we introduce GENA language model (GENA-LM), a suite of transformer-based foundational DNA language models capable of handling input lengths up to 36 000 base pairs.

Russia's invasion of Ukraine continues to have a devastating effect on the well-being of Ukrainians and their environment. We evaluated a major environmental hazard caused by the war: the potential for groundwater contamination in proximity to the Zaporizhzhia Nuclear Power Plant (NPP). We quantified groundwater vulnerability with the DRASTIC index, which was originally developed by the United States Environmental Protection Agency and has been used at various locations worldwide to assess relative pollution potential.

Background: Currently, there remains a high percentage of complications after lumbar discectomy, while there is no uniform tactic to prevent their development. Purpose of the study was to compare the clinical efficacy and return to work rate (RWR) after total disk replacement (TDR) and microsurgical lumbar discectomy (MLD) in railway workers with lumbar disk herniation (LDH).
Methods: We randomly assigned 75 patients out of a total of 81 patients, between 25 and 35 years of age who had one level LDH to undergo single-level TDR surgery (group I, n=37) or MLD surgery (group II, n=38) in the L4-L5 or L5-S1 segments.

The impact of thermal treatment for roasting on pine nuts from two geographical regions in Russia (Vladivostok and Baikal) was studied. They were roasted at 180 °C for 20 min in an oven. The aim was to establish the changes that occurred in the chemical (proteins, lipids, carbohydrates, ash, fibers), lipid composition (fatty acids, tocopherols, sterols, phospholipids), and physicochemical characteristics (peroxide value, acid value, iodine value, conjugated dienes and trienes) after roasting of the pine nuts.

The human genome contains millions of candidate cis-regulatory elements (cCREs) with cell-type-specific activities that shape both health and many disease states. However, we lack a functional understanding of the sequence features that control the activity and cell-type-specific features of these cCREs. Here we used lentivirus-based massively parallel reporter assays (lentiMPRAs) to test the regulatory activity of more than 680,000 sequences, representing an extensive set of annotated cCREs among three cell types (HepG2, K562 and WTC11), and found that 41.

Autologous haematopoietic stem cell transplantation (AHSCT) is a treatment option for relapsing forms of multiple sclerosis (MS) that are refractory to disease-modifying therapy (DMT). AHSCT after failure of high-efficacy DMT in aggressive forms of relapsing-remitting MS is a generally accepted indication, yet the optimal placement of this approach in the treatment sequence is not universally agreed upon. Uncertainties also remain with respect to other indications, such as in rapidly evolving, severe, treatment-naive MS, progressive MS, and neuromyelitis optica spectrum disorder (NMOSD).

This study investigates the nonlinear dynamics of a system with frequency-dependent stiffness using a MEMS-based capacitive inertial sensor as a case study. The sensor is positioned directly on a rotating component of a machine and consists of a microbeam clamped at both ends by fixed supports with a fixed central proof mass. The nonlinear behavior is determined by electrostatic forces, axial and bending motion coupling, and frequency-dependent stiffness.
