Intranasal administration of insulin to rats with forebrain ischemia and reperfusion decreases the intensity of autophagy and apoptosis in hippocampus and frontal brain cortex, possible mechanism of unsulin action
Authors: Zakharova I. O. , Bayunova L. V. , Avrova D. K. , Avrova N. F.
Published: August 2024

Rat forebrain ischemia and subsequent three-day reperfusion were found to result in an increase in the levels of autophagy marker LC3B-II and glial fibrillary acidic protein (GFAP) and activation of caspase-3 in the hippocampus and frontal cortex. At the same time, intranasal administration of 0.5 IU insulin to rats with forebrain ischemia and reperfusion (before ischemia and daily during reperfusion) markedly and significantly diminished the level of LC3B-II and caspase-3 activity in the hippocampus and frontal cortex. It demonstrates the ability of insulin to inhibit the activation of autophagy and apoptosis in forebrain structures during ischemia and reperfusion. It was not possible to find out a significant decrease in the level of GFAP in these brain structures under the influence of insulin administration to animals. Intranasal administration of insulin has been found to activate the protein kinase Akt (which activates the mTORC1 complex, known to inhibit autophagy processes) and to inhibit the protein kinase AMPK (initiating autophagy processes) in the hippocampus and cerebral cortex of rats with forebrain ischemia and reperfusion. These effects of insulin apparently underly its ability to diminish the autophagic and apoptotic neuronal death. The data on the modulation by insulin, administered intranasally to rats with forebrain ischemia and reperfusion, of Akt and AMPK activities are in agreement with more detailed studies of the possible mechanism of the neuroprotective action of insulin, which we previously made in vitro on cortical neurons under oxidative stress conditions.
Dominants in plant communities: the nature of impact on biomass determines the thresholds of impact on local species richness
Authors: Akatov V. V. , Akatova T. V. , Eskina T. G. , Sazonets N. M. , Chefranov S. G.
Published: August 2024

In accordance with existing ideas, a state of dominance in plant communities by some species (including alien and expansive ones) can be achieved through the use of resources of other species (1), also and additionally through the use of previously unused resources (2), also and additionally by allelopathy or changes in environmental conditions (3). It is believed that in the first case this process does not affect the total biomass of communities, in the second it is accompanied by its increase, in the third it is mainly reduced. It can be assumed that the mechanism of increasing the degree of dominance of individual species also determines the nature of their influence on species richness. To test this hypothesis, we compared the participation of dominants, biomass, and the number of accompanying species in a series of biomass samples taken from 67 sites of terrestrial plant communities in the Western Caucasus and Ciscaucasia (high and low mountain meadows and steppes, communities of wastelands, old fallows, etc.). The results showed that 1) in these communities different variants of the relationship between the participation of dominants and biomass are observed, which means that, presumably, different mechanisms of influence of dominants on accompanying species are realized; 2) the distribution of these mechanisms differs in natural (semi-natural) and synanthropic communities, with the dominance of native and alien species; 3) the nature of the impact of dominants on biomass determines the thresholds for their impact on local species richness; 4) in synanthropic communities with the dominance of alien species, these thresholds are more pronounced than in communities of other types. At the same time, our earlier obtained results showed that native and alien species do not often reach the degree of dominance, the excess of which poses a significant threat to the species richness of plant communities.
Peculiarities of Siberian fir photosynthesis model as a result of plant adaptation to environmental conditions
Authors: Tarasov S. I. , Gerling N. V.
Published: August 2024

Siberian fir (Abies sibirica Ledeb.) is one of the main forest-forming species of northeastern European Russia. Compared to other forest-forming species, Siberian fir is poorly studied and there are no integral models describing the dynamics of fir photosynthesis depending on environmental factors and growing conditions. Modeling of intensity of fir photosynthesis depending on vertical gradients of environmental factors and anatomo-morphological structure of Siberian fir needles varying from the location within the vegetation canopy by height is the purpose of the present study. The study was conducted in the middle taiga subzone of the Komi Republic in a bilberry-sphagnum spruce forest at two altitudinal levels. The objects of the study are represented by two Siberian fir trees occupying different positions in the stand structure, one being a part of the main tier, the other being a part of the second tier. The CO2 assimilation rate of fir needles, the intensity of incident photosynthetically active radiation, air temperature, relative air humidity, and atmospheric CO2 concentration were measured in the crowns of selected trees on uncut shoots; the anatomical and morphological structure of fir needles depending on their height position in the stand structure was studied. A regression equation modeling the dependence of CO2 assimilation rate by Siberian fir needles on environmental factors was obtained on the basis of experimental data. Validation showed the adequacy and statistical significance of the model. Specificity of the model and anatomo-morphological features of Siberian fir needles depending on their height in the stand was revealed.

Published: August 2024

This paper considers the problem of constructing compartmental models of dynamic systems by using a software package for symbolic calculation written in Julia. The software package is aimed at unifying the formalized construction of compartmental models, taking into account the meaningful description of possible interactions among compartments and the influence of various factors on the evolution of systems. An approach to the development of the instrumental and methodological basis for modeling the dynamic systems the behavior of which can be described by one-step processes is developed. The proposed software package enables the symbolic representation of the differential equations of the model in both stochastic and deterministic cases. It is implemented in Julia and uses the Julia Symbolics computer algebra library. A comparison between the Julia Symbolics tools and some other computer algebra systems is carried out. The application of the developed software package to a compartmental model is considered. The results can be used to solve problems of constructing and studying dynamic models in natural sciences that are represented by onestep processes.
Lower bounds for the rank of a matrix with zeros and ones outside the leading diagonal
Authors: Seliverstov A. V. , Zverkov O. A.
Published: August 2024

We have found a lower bound on the rank of a square matrix, where every entry in the leading diagonal is neither zero nor one, but every entry outside the leading diagonal is either zero or one. The rank of such a matrix is at least half the order of the matrix. Under an additional condition, the lower bound is one higher. This condition means that some auxiliary system of linear equations has no binary solution. Examples are given showing the achievability of the lower bound. This lower bound on the rank allows us to reduce the problem of finding a binary solution to a system of linear equations, where the number of linearly independent equations is sufficiently large, to a similar problem in a smaller number of variables. Restrictions on the existence of a large set of solutions are found, each of which differs from binary one by the value of one variable. In addition, we discuss the possibility of certifying the absence of a binary solution to a system of a large set of linear algebraic equations. Estimates of the running time for calculating the rank of a matrix with the SymPy computer algebra system are also given. It is shown that the matrix rank over the field of residues modulo a prime number is calculated in less time than is usually required to calculate the rank of a matrix of the same order over the field of rational numbers.
Quaternion Solution of the Problem on Optimum Control of the Orientation of a Solid (SPACECRAFT) with a Combined Quality Criteria
Authors: Levskii M. V.
Published: August 2024

The problem on optimal rotation of a solid (spacecraft) from an arbitrary initial to a prescribed final angular position in the presence of restrictions on the control variables is studied. The turnaround time is set. To optimize the rotation control program, a combined quality criterion that reflects energy costs is used. The minimized functional combines in a given proportion the integral of the rotational energy and the contribution of control forces to the maneuver. Based on the Pontryagin’s maximum principle and quaternion models of controlled motion of a solid, an analytical solution of the problem has been obtained. The properties of optimal motion are revealed in analytical form. To construct an optimal rotation program, formalized equations and calculation formulas are written. Analytical equations and relations for finding optimal control are given. The key relations that determine the optimal values of the parameters of the rotation control algorithm are given. In addition, a constructive scheme for solving the boundary value problem of the maximum principle for arbitrary turning conditions (initial and final positions and moments of inertia of a solid) is described. For a dynamically symmetric solid, a closed-form solution for the reorientation problem is obtained. A numerical example and mathematical modeling results that confirm the practical feasibility of the developed method for controlling the orientation of a spacecraft are presented.

A Graphical User Interface Based on Logistic Regression Approach for Malarial Detection
Authors: Kumar Manish , Sarkar Bikash
Published: August 2024

Malaria (a mosquito-infected disease) is one of the deadliest communicable diseases in the world. The disease causes a significant global health challenge. According to the World Health Organisation (WHO), millions of deaths occur every year worldwide. The mortality rate poses a challenge to authority and management. Over the years, mathematical and machine learning (ML)-based techniques have been developed to mitigate the scenario. In this study, ML-based prediction techniques are investigated to predict the presence of malaria in individuals. More specifically, three ML-based techniques—Logistic Regression (LR), Support Vector Machine (SVM), and Random Forest (RF)—are employed to differentiate their prediction performance (namely, classification accuracy, precision, recall, and F-score) over a created database (D) consisting of 350 records. Among the adopted techniques, the LR technique shows overall better performance over the test data chosen from D. A graphical user interface (GUI) based on LR is also developed to detect the presence or absence of malaria in any individual. The time spent by the GUI to report the absence or presence of the disease is definitely less than the time spent by malaria experts.
Graded Quantum Noise in Quantum Field Theories
Authors: Parthasarathy Harish
Published: August 2024

The aim of this article is to introduce into quantum field theory, \(\Bbb Z_n\times\Bbb Z_n\) graded quantum stochastic calculus with the aim of generalizing supersymmetric quantum stochastic calculus to situations where rather than just two kinds of particles, Bosons and Fermions, we can have particles of \(n^2\) kinds graded by \(\Bbb Z_n\times\Bbb Z_n\) rather than by \(\Bbb Z_2\). Following the suggestions at the end of the book [1] by Timothy Eyre, we introduce the \(\Bbb Z_n\times\Bbb Z_n\) graded tensor product by means of a bi-character constructed from a primitive \(n^{th}\) root of unity and then proceed to grade both system and noise operators in Boson Fock space. This enables us to construct consistent Lie algebra supercommutation relations graded by \(\Bbb Z_n\times\Bbb Z_n\) for appropriately defined graded quantum stochastic processes. Using the \(\Bbb Z_n\times\Bbb Z_n\) graded quantum noise for driving the Hudson-Parthasarathy noisy Schrodinger equation combined with an appropriate non-demolition counting measurement process, we formulate the problem of \(\Bbb Z_n\times\Bbb Z_n\) graded quantum filtering as a generalization of the Belavkin filter. After that, we discuss how to construct Bosonic quantum noise out of these graded quantum noise processes by tensoring with appropriately graded system operators and then how to add such noise to Bosonic field theories including quantum gravity. We also discuss quantum noise in string theories and a little bit of string field theories wherein the action for the string field is chosen based on the BRST charge quantization process that defines the condition for a state to be physical in the absence of ghosts. The addition of higher degree terms in the string field action is then based on the condition that the action should satisfy the quantum master equation for invariance of the matrix elements under the choice of the gauge fixing functional. We suggest methods by which quantum noise fields can also be taken into account in string field theories. The entire aim of adding quantum noise to a quantum field theory is motivated by the fact that the resulting noisy Hamiltonian should describe a Hudson-Parthasarathy noisy Schrodinger equation with unitary evolution on the joint System-Bath Hilbert space so that after tracing out over the bath, one obtains a quantum dynamical semigroup of TPCP maps describing system evolution alone for open quantum systems. For noisy quantum field theories, finally, we explain how to compute propagator corrections caused by noise.
