Relativistic description of asymmetric fully heavy tetraquarks in the diquark-antidiquark model
Masses of the ground, orbitally and radially excited states of the asymmetric
fully heavy tetraquarks, composed of charm (c) and bottom (b) quarks and
antiquarks are calculated in the relativistic diquark-antidiquark picture. The
relativistic quark model based on the quasipotential approach and quantum
chromodynamics is used to construct the quasipotentials of the quark-quark and
diquark-antidiquark interactions. These quasipotentials consist of the
short-range one-gluon exchange and long-distance linear confinement
interactions. Relativistic effects are consistently taken into account. A
tetraquark is considered as a bound state of a diquark and an antidiquark which
are treated as a spatially extended colored objects and interact as a whole. It
is shown that most of the investigated tetraquarks states (including all ground
states) lie above the fall-apart strong decay thresholds into a meson pair. As
a result they can be observed as wide resonances. Nevertheless, several
orbitally excited states lie slightly above or even below these fall-apart
thresholds, thus they could be narrow states.Comment: 24 pages, 1 figur
Quantum geometrodynamics of the Bianchi IX model in extended phase space
A way of constructing mathematically correct quantum geometrodynamics of a
closed universe is presented. The resulting theory appears to be
gauge-noninvariant and thus consistent with the observation conditions of a
closed universe, by that being considerably distinguished from the conventional
Wheeler - DeWitt one. For the Bianchi-IX cosmological model it is shown that a
normalizable wave function of the Universe depends on time, allows the standard
probability interpretation and satisfies a gauge-noninvariant dynamical
Schrodinger equation. The Wheeler - DeWitt quantum geometrodynamics is
represented by a singular, BRST-invariant solution to the Schrodinger equation
having no property of normalizability.Comment: LaTeX, 18 pages, to be published in Int. J. Mod. Phys.

Gas-liquid chromatography is widely used in the process of forensic toxicological examinations, but data about application of GLC with flame-ionization and mass-spectrometry detection for secnidazole determination in analytical toxicology are absent.Aim. To develop GLC/FID- and GLC/MS-procedures for the quantitative determination of secnidazole and carry out step-by-step validation of the procedures developed in the variant of the method of additions.Results and discussion. The chromatographic conditions has been chosen for secnidazole determination by the method of GLC in two variants of performance with flame-ionization and mass-spectrometry detection with the temperature program changing during the analysis from 70 Β°C to 250 Β°C or 320 Β°C. Retention times for secnidazole are 8.97 min and 11.74 min. To prove the possibility of application of the procedures proposed in further analysis their validation has been carried out in the variant of the method of additions. Such validation parameters as in-process stability, linearity, accuracy and precision have been estimated by model solutions.Experimental part. The GLC/FID-analysis: HP 6890 Hewlett Packard; ΠΠ -1 ΓΈ0.32 mm Γ 30 m, 0.25 ΞΌm; thermostat β 70 ΒΊΠ‘ (3 min), 40 ΒΊΠ‘/min to 180 ΒΊΠ‘ (2 min), 40 ΒΊΠ‘/min to 250 ΒΊΠ‘ (3 min); injector β 280 ΒΊΠ‘; detector β 280 ΒΊΠ‘; volume rate of a carrier gas (helium) β 1.5 ml/min; split mode β 1 : 2. The GLC/MS-analysis: Agilent 6890N/5973N/7683; ΠΠ -5MS ΓΈ0.25 mm Γ 30 m, 0.25 ΞΌm; DB-17MS ΓΈ0.25 mm Γ 30 m, 0.15 ΞΌm; columns are connected sequentially through Deans switch; thermostat β 70 ΒΊΠ‘ (2 min), 45 ΒΊΠ‘/min. to 210 ΒΊΠ‘, 6 ΒΊΠ‘/min to 320 ΒΊΠ‘ (12.56 min); transfer line β 280 ΒΊΠ‘; ion source β 230 ΒΊΠ‘; quadrupole β 150 ΒΊΠ‘; electron impact β 70eV; 40-750 m/z; injector β 250 ΒΊΠ‘; splitless mode; inlet carrier gas (helium) pressure: 1st column β 26.06 psi, 2nd column β 19.30 psi.Conclusions. New procedures for the quantitative determination of secnidazole by the method of GLC/FID and GLC/MS have been developed. Their validation has been carried out, and acceptability for application has been shown.ΠΠ°Π·ΠΎ-ΠΆΠΈΠ΄ΠΊΠΎΡΡΠ½Π°Ρ Ρ

The distributed architecture of monitoring and management systems based on the SNMP protocol, the MIB databases and the centralized architecture based on the SDN network concept and the Openflow protocol are considered. The advantage of centralized monitoring and control is the ability to form a holistic view of the network status, respectively, to calculate the global optimum control and load balancing. The disadvantage is the low resiliency of the network, the complexity of managing a large system. Monitoring and management of such a complex system is possible with the help of decentralization, the creation of a hierarchical structure, the use of heuristic or metaheuristic methods for optimizing large systems. A method with sliding a posteriori optimization, which allows to achieve the optimal number of hierarchy levels and the optimal number of devices on the same level, is proposed.Π Π°ΡΡΠΌΠΎΡΡΠ΅Π½Ρ ΡΠ°ΡΠΏΡΠ΅Π΄Π΅Π»Π΅Π½Π½Π°Ρ Π°ΡΡ

Fully-heavy tetraquark spectroscopy in the relativistic quark model
Masses of the ground and excited (1P, 2S, 1D, 2P, 3S) states of the
fully-heavy tetraquarks, composed of charm () and bottom () quarks and
antiquarks, are calculated in the diquark-antidiquark picture within the
relativistic quark model based on the quasipotential approach and quantum
chromodynamics. The quasipotentials of the quark-quark and diquark-antidiquark
interactions are constructed similarly to the previous consideration of mesons
and baryons. Relativistic effects are consistently taken into account. A
tetraquark is considered as a bound state of a diquark and an antidiquark. The
finite size of the diquark is taken into account, using the form factors of the
diquark-gluon interaction. It is shown that most of the investigated states of
tetraquarks lie above the decay thresholds into a meson pair, as a result they
can be observed only as broad resonances. The narrow state X(6900) recently
discovered in the di- production spectrum by the LHCb, CMS and ATLAS
Collaborations corresponds to an excited state of the fully-charmed tetraquark.
Other recently discovered exotic heavy resonances X(6200), X(6400), X(6600),
X(7200), X(7300) can also be interpreted as the different excitations of the
fully-charmed tetraquark.Comment: 36 pages, 2 figure
Importance of serous intraepithelial ovarian tubal carcinomas in the occurrence of "high-grade" serous carcinomas and / or peritoneal serous carcinomas of unknown primary origin.
Studies of the recent decades on serous pelvic adenocarcinomas in women have set the goal of distinguishing between two diagnostic units: "low-grade" and "high-grade" carcinomas. The predecessor of the "low-grade" variant (type I) is considered to be a borderline serous tumor / atypical proliferative serous tumor (8442/1), which according to the International Classification of Diseases for Oncology ICD-OΒ 2013 of the female reproductive system refers to non-specific, borderline tumors and tumors with unpredictable clinical behavior. The predecessors of the βhigh-gradeβ variant (type II) are serous tubular intraepithelial carcinomas (in situ) or βhigh-gradeβ serous invasive tubal carcinomas, since they have the TP53 mutation identical to βhigh-gradeβ ovarian carcinoma, an aberrant p53 protein expression, high proliferative activity, and significant genomic instability. In addition, according to the carcinogenesis of "high-grade" serous ovarian carcinoma with metastases to the peritoneum, it can also be interpreted as "pelvic high-grade serous carcinoma". A retrospective analysis of the histological, morphometric and immunohistochemical characteristics of the biopsy material of 31 women aged from 28 to 76 years (mean 57.32Β±11.54; median 57), divided into 3 groups, was carried out. Group 1: 14 observations of the tubal epithelium (8 tubes without pathological changes (subgroup 1a) and 6 with signs of intraepithelial neoplasia (subgroup 1b); group 2: 12 cases of serous adenocarcinoma of the ovary of the βhigh-gradeβ variant; group 3: 6 metastatic peritoneal serous carcinoma without a known primary site. Results. Group immunophenotypes showed uniformity in the expression of markers CK7 (+, +/-), CK20 (-), WT-1 (+), CA125 (+, +/-), with an affinity to distal uterine tube fragments. The expression of p53 in all groups with signs of carcinomas (compared with the control subgroup 1a without atypia) was divided into two options - negative samples and samples with overexpression, where no statistically significant difference was found (p>0.05), which is possibly a single way of carcinogenesis. The morphometric study revealed a significant difference in the area of the nuclei between group 3 and the first three groups (1a, 1b, 2), which indicates the similarity of ovarian and tubal neoplasias and uterine tube epithelium. The number of intranuclear reactions with ER and PGR progressively decreased from group 1 to group 3, with an increase in cases with ER (+/-) / PGR (+/- or -) to 50% in group 3, which greatly complicated the diagnostic search for unknown carcinomas of primary localization. HER-2-new expression revealed a possible amplification (gradation 2 + / 3 +) only in group 2 at the level of 16.67% and in group 3 at the level of 33.33%
Determination Methods Of Defrosted Protein-vegetable Mixtures Parameters Development
The aim of the work is to develop methods of investigating the influence of semolina and extruded semolina on quality and quantity parameters of mixtures with milk-protein concentrates in a cycle of freezing-defrost that allows to substantiate resource-saving in semi-products manufacturing.Obtained results of changes of the quality of protein-vegetable mixtures after the effect of negative temperatures confirm cryo-protective properties of carbohydrates of products of wheat processing.There were studied methods of extracting proteins of whey for getting albumin mass and using in the composition of milk-protein concentrates. It was established, that adding collagen-containing ingredients in amount 0,4 % for intensifying thermal coagulation of whey proteins decreases the duration of precipitation to (55Β±2) and (40Β±2) min respectively depending on a type of raw material processing. There were studied both native whey and protein concentrate, obtained by the method of ultra-filtration with mass share of dry substances (16Β±2) %.The method of thermal analysis determined a cryoscopic temperature of sour-milk fatless cheese and also albumin mass, obtained using Β«Collagen pro 4402Β». The calculation method, based on cryoscopic temperature indices determined an amount of moisture, frozen out in milk-whey mixtures with wheat processing products. The presented information is enough for estimating traditional modes of freezing milk-protein concentrates objectively.The obtained results of the studies indicate the effectiveness of the offered methods for determining parameters of protein-vegetable mixtures after defrosting. Measurements of quality parameters may be used for correcting mass losses of concentrates effectively
Proliferation activity and hormonal status of atypical hyperplasia and endometrioid adenocarcinoma of the endometrium
Atypical hyperplasia of the endometrium is a precancerous condition for endometrioid adenocarcinoma of the endometrium, which is the largest group among malignant neoplasms of the uterine body, according to the Cancer Registry, the mortality rate from which took the 3rd place in 2021. The absence of specific clinical manifestations complicates diagnostics at the early stages of the process, which necessitates the study of histological and immunohistochemical criteria to verify the diagnosis.
The aim of the study. To improve the differential diagnostic morphological and immunohistochemical criteria for the diagnosis of atypical hyperplasia and endometrioid adenocarcinoma of the endometrium, using the latest international classification data.
Materials and methods. Retrospective analysis of 76 cases of postoperative material of women for the period from 2020 to 2022 with a diagnosis of βendometrioid adenocarcinoma of the endometriumβ β 61 cases and βendometrial hyperplasia with atypiaβ β 15 included an assessment of histological, immunohistochemical features, followed by statistical processing of the obtained results.
Results. The incidence of endometrioid adenocarcinoma of the endometrium and atypical endometrial hyperplasia occurs in the premenopausal and menopausal periods. The expression level of the Ki-67 marker is directly proportional to the degree of tumor malignancy (p < 0.05). Estrogen receptors decrease as the degree of tumor malignancy increases. Progesterone receptors are equally present in endometrioid adenocarcinomas and atypical endometrial hyperplasia (p < 0.05).
Conclusions. The necessity of using the Ki-67 marker and determining the hormonal status in endometrioid adenocarcinomas of the endometrium and atypical hyperplasia of the endometrium is argued
