Background.
The probability of seizures after endoscopic surgical treatment of hydrocephalus may comprise up to 9.5%, therefore accounting for a need to find solutions for alleviating the surgical ...trauma to the brain. One option to this problem might be based on using “seamless” neurosurgery, particularly endoscopes with a minimal outer sheath diameter (needle endoscopes, shunt endoscopes).
Objective:
to evaluate major outcomes of surgically treated epilepsy, cerebral haemodynamics and electroencephalogram (EEG) in children with hydrocephalus and concomitant drug-resistant epilepsy before and after endoscopic ventriculocysternostomy of the third ventricular floor by using a semi-rigid needle endoscope.
Material and methods.
In the early and remote postoperative periods, no epileptic seizures were observed in 57.1% of subjects (Engel Class I). Mean seizure frequency decreased from 12.9±6.1 to 0.82±0.31 per month (p<0.01). A significant decline in slow-wave amplitude and the paroxysmal index from 19.1±2.5% to 6.9±1.7% (p<0.01) were observed, as well as improvement of cerebral hemodynamics in the form of increased mean cerebral blood flow by 29.1±4.3% (p<0.01), mean circulating blood volume by 22.4±5.27% (p<0.05) and decreased mean transit time by 12.8±2.5% (p<0.05).

The article presents a review of Russian and international literature dedicated to the problem of painful ejaculation. Mentions of this type of disorders are quite rare. Its real incidence remains ...unknown. Connections between painful ejaculation and infectious and inflammatory diseases (orchitis, epididymitis, prostatitis, vesiculitis, urethritis), previous surgeries (in particular, transurethral resection of the prostate), administration of certain drugs (for example, antidepressants), rare congenital developmental anomalies are considered. Data on the effectiveness of conservative and surgical treatment are presented.
A plane steady problem of fracture mechanics for a burning deformable solid propellant attenuated by a crack-type cavity with a burning surface is considered. The crack-type cavity is assumed to have ...tip zones with bonds between the faces, and mixed boundary conditions are imposed on the propellant charge boundary. The problem of equilibrium of a propellant charge containing a crack-type cavity reduces to solving a system of nonlinear singular integrodifferential equations with a Cauchy-type kernel. Based on the solution obtained, the normal and tangential forces in the tip zones of the crack-type cavity are found. Local conditions determining stability (safety) of the solid propellant burning regime are found.

First experimental results are presented on event-by-event net-proton fluctuation measurements in Pb–Pb collisions at sNN=2.76 TeV, recorded by the ALICE detector at the CERN LHC. The ALICE detector ...is well suited for such studies due to its excellent particle identification capabilities and large acceptance, which is crucial for fluctuation analysis. The studies are focussed on second order cumulants, but the analysis technique used is more general and will be applied, in the near future, also to higher order cumulants.

The article considers the results of study of role of physical characteristics in ‘productivity during drought’ and drought tolerance of spring and winter wheat. It was found, that drought tolerance ...of durum wheat in different hydro thermal conditions and drought types was connected with different characteristics. It allowed us to conclude that a more reliable assessment was possible when using several methods and technologies simultaneously, based on various physiological criteria. It was revealed that the more tolerant to drought varieties showed larger figures of water-holding capacity. Among the traits which allow recognizing drought tolerance we can note high values of water loss while wilting and low values of a net productivity of photosynthesis. We found essential to use a math method of statusmetria to make large amount of productive and physiological data more informative and compact. The use of statusmetria gave us an opportunity to find differences in the samples’ reaction to drought depending on the time and duration. We found and gave quantitative assessment of those morpho physiologic parameters, which show the most productivity and stability under definite hydro thermal conditions. To create drought tolerant primary material we suggest combining the study of breeding material by screening, express methods with further detailed study of yield stability and morpho physiologic features of drought tolerance of the samples.

This article analyzes new data on compactum wheat (Triticum compactum Host.) collected in the Nakhchivan Autonomous Republic (NAR). Two expeditions to various parts of AR, supported by the Science ...Development Foundation, along with other species, collected 78 accessions of compactum wheat belonging to the groups of varieties convar. rigidicompactum, convar. inflatum, and convar. compactum. The majority of samples (85,5 %) belonged to the varieties var. splendidorigidum, var. fetissovii, var. asiaticicterinum, var. erinaceum, etc., which are a subgroup of subconvar. rigidicompactum. A wide intraspecific variability in growth habit, earing data, resistance to yellow rust, height, architectonic of plants, and ear parameters was revealed.
The article presents information on the distribution of bread wheat in South Caucasus, including Azerbaijan. The subspecies and varietal composition and history of traditional and newly bred ...varieties of bread wheat are considered. It is shown that ecotype-contrasting groups of varieties should be used to obtain reliable scientific results on the comparative study of physiological and biochemical characteristics.
This study delves into the analysis of public sentiment within Azerbaijani social media comments and news articles employing Natural Language Processing methodologies and sentiment analysis ...techniques. The research explores distinct sentiment narratives in social media and news contexts, drawing from a dataset comprising 38,000 comments and 12,000 news articles. In our investigation, we evaluated a spectrum of models, including BERT, GPT-3.5-Turbo, LSTM, SVM, and LR which are complemented with Bag of Words, TF-IDF, and FastText vectorizers, alongside word embedding models. Additionally, we employ various preprocessing techniques, such as eliminating links and mentions (@ or 'at'), transforming emojis into a readable format, and performing stemming and stop word removal on news articles. Our trained models demonstrate superior performance compared to the Large Language Models which suggests the efficacy of our tailored approach in capturing polarity within Azerbaijani social media and news data. The findings underscore the superiority of SVM over other classification models across both social media and news articles. Moreover, it contributes valuable insights into sentiment analysis in diverse linguistic contexts, with implications for understanding public sentiment dynamics in Azerbaijani media.
