A study of the nonlinear dynamics inside the exoplanetary system Kepler-22 using MATLAB® software
Authors: Hysa Azem 
Published: April 2024

Kepler is a discovery-class mission designed to determine the frequency of Earth-radius planets in and near the habitable zone of solar-type stars. A habitable zone of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for habitable planets is whether they host life.
The aim of this paper is to study the motion of a “test particle” inside the exoplanetary system Kepler-22. This system consists of a sun-like star, Kepler-22, and a terrestrial exoplanet, Kepler-22b. This exoplanet is situated in the habitable zone of its star. Kepler-22b is located about 180 pc from Earth in the constellation of Cygnus. It was discovered by NASA’s Kepler Space Telescope in December 2011 and the planet is about 2.4 times the radius of Earth. Scientists don't yet know if Kepler-22b has a rocky, gaseous or liquid composition.
In this study, let’s derive Lagrange points and perform several numerical tests to discover different possible orbits around the star Kepler-22. From many numerical tests performed, it is also possible to found two tadpole orbits around the Lagrange points L4 and L5 and a tadpole orbit around the exoplanet Kepler-22b, which encircles the two Lagrange points L1, and L2. Some of these orbits are found in the habitable zone and others outside. We have also examined the possibility of the existence of an exomoon around the terrestrial exoplanet Kepler-22b. In this case we have considered the mass of this exomoon.
The Circular Restricted Three-Body Problem is used in this study. If it is further assumed that the third body (for example a planet, satellite, an asteroid or just a “test particle”) travels in the same plane as the two larger bodies, then there is the Planar Circular Restricted Three-Body Problem

Published: April 2024

The emergency department plays a fundamental role in hospitals and critically affects a hospital's overall efficiency. Inadequate staff planning in emergency departments generates high costs, overcrowding, and patient dissatisfaction due to long waiting times, possibly putting the patient's health and life at risk. This research designed two mixed integer linear programming mathematical models. The first determined the optimal number of physicians required per shift and weekday in an adult emergency department to minimize the deviation between available and required capacity. The results of the optimization model would reduce by 16.07 % the required medical office staff per week, from 56 physicians in the current situation to 47, reducing staffing costs without impacting waiting times. Moreover, the overall physician utilization would be 95.01 % compared to 77.79 % in the current situation, indicating an adequate distribution of physicians on each shift of each day according to patient demand. These results contribute to the problem of high medical staff costs and overcrowding without sacrificing timeliness and quality of care. In contrast, the second model that minimized the number of physicians considering capacity constraints would increase the staff by 7.14 % concerning the current situation. This research was based on a model presented in the literature, but the objective function included the deviation variables as unrestricted in sign and a constraint to ensure that they were positive. The first model designed is presented as a tool to support emergency department managers in the medium-term planning of medical staff, ensuring an optimal solution to this problem
Development of a new method for solving problems of compressing various liquids with the manifestation of the “microcrack-liquid” effect
Authors: Mammadova Maleyka 
Published: April 2024

The object of the study is the peculiarities of the movement of viscous and anomalous liquids in plane-parallel and plane-radial microcracks. The problem of hydrodynamic features of fluid motion in the considered objects – channels was studied.
Currently, the mechanical properties of liquids are being studied in pipes of various sizes. There are studies that claim that in small pipes the resistance to fluid movement increases compared to calculation formulas, and this phenomenon is explained by various qualitative factors.
To study this mechanical phenomenon, a device equipped with plane-parallel and plane-radial microcracks was developed. Numerous experiments carried out in microcracks have shown that for each liquid there is a critical crack opening and the following pattern has been discovered.
The essence of the obtained results is that during the movement (or static state) of a fluid in a microcrack (or an equivalent porous medium) with an opening less than critical, a viscous one-parameter fluid (water, viscous oil, etc.) becomes two-parameter, and two-parameter (resinous oils, polymers) solutions, etc.) increase their rheological parameters.
In this case, additional resistance arises against the movement of the fluid, which was named as a new hydrodynamic effect in the “microcrack-liquid” system.
A new phenomenon has been revealed, in which the motion of viscous and anomalous fluids in micron-sized fractures is described by other rheological curves. This allowed to take this hydrodynamic fact into account when solving the compression problem.
In this regard, problems are solved taking into account the “microcrack-liquid” effect.
The results of the research require taking into consideration the crack effect in estimating the parameters of the technological processes system and technical devices “microcrack-fluid”. Machines and mechanisms must additionally have nodes that would prevent this effect. This is of scientific and practical importance for various fields of the industry, machine manufacturing, instrument manufacturing, chemical technology and medicine

Authors: Hu Xuanyi , Lv Xinxin , Zhang Lingzhu , Li Shan-Shan , Jin Xin 
Published: April 2024

:
Pulmonary Hypertension (PH) is a complex cardiovascular disorder characterized by
elevated blood pressure in the pulmonary arteries. Current therapeutic approaches for PH have
limitations in addressing the underlying molecular mechanisms. This article explores the potential
of noncoding RNAs (ncRNAs), including microRNAs (miRNAs), long noncoding RNAs
(lncRNAs), and circular RNAs (circRNAs), delivered through Lipid-Based Nanoparticles
(LNPs) as a novel treatment strategy. These ncRNAs play critical roles in regulating vascular
function and are implicated in PH pathogenesis. LNPs provide a promising method for the efficient
and targeted delivery of ncRNAs. Advances in LNP technology, including the incorporation
of R8 peptide modification, have shown promise in enhancing the delivery and efficacy of
ncRNAs in PH models. Challenges such as biocompatibility, toxicity, and precise targeting must
be addressed as these therapies move toward clinical application. The potential of personalized
medicine and the integration of artificial intelligence in LNP design are discussed as prospects.
In conclusion, ncRNA lipotherapeutics delivered via LNPs offer a transformative approach to
treating PH, potentially leading to more effective management and improved patient outcomes
in the future. However, continued research and clinical trials are necessary to fully realize their
therapeutic potential in the field of PH treatment.

Abstract::
Respiratory viruses have caused many pandemics from past to present and are among
the top global public health problems due to their rate of spread. The recently experienced
COVID-19 pandemic has led to an understanding of the importance of rapid diagnostic tests to prevent
epidemics and the difficulties of developing new vaccines. On the other hand, the emergence
of resistance to existing antiviral drugs during the treatment process poses a major problem for society
and global health systems. Therefore, there is a need for new approaches for the diagnosis,
prophylaxis, and treatment of existing or new types of respiratory viruses. Immunoglobulin Y antibodies
(IgYs) obtained from the yolk of poultry eggs have significant advantages, such as high
production volumes, low production costs, and high selectivity, which enable the development of
innovative and strategic products. Especially in diagnosing respiratory viruses, antibody-based
biosensors in which these antibodies are integrated have the potential to provide superiority in
making rapid and accurate diagnosis as a practical diagnostic tool. This review article aims to provide
information on using IgY antibodies in diagnostic, prophylactic, and therapeutic applications
for respiratory viruses and to provide a perspective for future innovative applications.

Authors: Ling Jingxiu , Shao Jiacheng , Sun Chao , Tong Xin 
Published: April 2024

Introduction:
The cutter is a crucial excavation tool employed by Tunnel Boring Machines
(TBM) for tunneling underground passages. During operation, it undergoes intense impact loads,
which are transmitted to the bearings, thus posing a risk of bearing failure. Method: This paper combines
the Discrete Element Method (DEM) and Multibody Dynamics (MBD) by establishing a coupled
simulation patent model of the cutter and surrounding rock, various methods of cutter load profiles
are compared. The study investigates the variation patterns of multi-directional rock-breaking
loads on the cutter and validates the findings through wire-cutting experiments. Result: The research
findings indicate that the discrepancies between the simulated and experimental mean values of the
cutter's normal force and rolling force are 6.26% and 35.20%, respectively. The efficiency of cutter
load transmission to the outer ring of the bearing is 99.10%, leading to the characterization of the
vibration characteristics curve of the bearing's outer ring. Simultaneously, the mean square error of
the cutter load obtained through the coupled method and traditional method is 78.50 kN and 76.10
kN, respectively. In comparison, the experimental load's mean square error is 99.20 kN, indicating
that the coupled method better aligns with actual conditions. Conclusion: This research approach
serves as a reference for TBM cutter performance analysis and bearing fatigue analysis.
