An Analysis of the Instability Conditions and Water Vapor Transport Characteristics during a Typical Rainstorm in the Tarim Basin

In order to deepen the understanding of the occurrence mechanism and water vapor transport characteristics of the heavy rain process in the extreme arid region of Xinjiang, a rare heavy rain process in the Tarim Basin during the period of 18–22 July 2021 was comprehensively analyzed by using multi-source data. The results show that the upper tropospheric South Asian high was distributed in a “west-high-east-low” pattern during the rainstorm process, and the rainstorm area was located on the right side of the upper jet stream entrance area, while the middle-level Iranian high pressure, Baikal high pressure and Central Asian low pressure formed a “two-highs and one-low” circulation situation. The coupling of the high and low air jets and the strong vertical upward motion provided favorable dynamic conditions. Rainstorm water vapor mainly comes from the Mediterranean Sea, Central Asia and the Indian Ocean, and it enters the basin in four paths: west, east to west, west to east, and southwest and south. The water vapor mainly flows into the middle layer of the western boundary and the southern boundary and the lower layer of the eastern boundary, and it flows out from the middle and upper layer of the eastern boundary. The negative moist potential vorticity region at a low level has a strong indicator significance for the occurrence and development of heavy rain, and the superposition of positive and negative moist potential vorticity regions at vertical height is conducive to the occurrence and development of heavy rain.

Late relapse of chronic myeloid leukemia after allogeneic bone marrow transplantation points to KANSARL (KANSL1::ARL17A) alteration: a case report with insights on the molecular landscape

Chronic myeloid leukemia is a myeloproliferative neoplasm characterized by the presence of the Philadelphia chromosome and the consequent BCR::ABL1 oncoprotein. In the era before the introduction of tyrosine kinase inhibitors (TKIs), the only potentially curative treatment was allogeneic hematopoietic stem cell transplantation (HSCT). Here, we present the case of a patient affected by CML who experienced a relapse 20 years after allogeneic HSCT. Following relapse, the patient was treated with imatinib and bosutinib, resulting in a deep molecular response and successfully discontinued treatment. Additional analysis including whole-exome sequencing and RNA sequencing provided some insights on the molecular mechanisms of the relapse: the identification of the fusion transcript KANSL1::ARL17A (KANSARL), a cancer predisposition fusion gene, could justify a condition of genomic instability which may be associated with the onset and/or probably the late relapse of his CML.

Zhukovsky of trajectories of dynamic systems modeled by systems of three nonlinear differential equations of the first order. The aim of the work is to study the stability in the Zhukovsky sense of the trajectories of a dynamic system described by three autonomous nonlinear first-order differential equations using a differential geometric method called the accompanying coordinate reference method. The formulation of the stability problem in the Zhukovsky sense of the trajectories of dynamic systems described by systems of three nonlinear differential equations of the first order is considered. The definitions of stability of trajectories of a three-dimensional nonlinear system are specified. Using the accompanying coordinate reference, the conditions of exponential stability and instability according to Zhukovsky are obtained. The results can be used in studying the stability of processes in systems of natural science and technology, as well as in solving theoretical and applied problems of mathematical modeling and qualitative research of trajectories of nonlinear dynamic systems.

Component of the economic development of dairy processing enterprises

The article's purpose is a theoretical justification of the place of the financial component in the system of ensuring the economic development of milk processing enterprises. The scientific article is devoted to studying the financial component of the economic development of milk processing enterprises and the study of financial instruments and strategies that contribute to increasing their efficiency and sustainability. The research method is the determination of factors affecting the financial stability of milk processing enterprises and the development of recommendations for optimizing financial management. As a component of economic development, financial resources are significant for enterprises, as this is the amount of their own, borrowed, and borrowed resources, the effective use of which determines a stable financial condition: solvency, financial stability, and liquidity. The dependence of milk processing enterprises on market factors, such as prices for raw materials and products, consumer demand, and competition, has been established, so financial results are determined by the ability to adapt to changes in the market. It is noted that milk processing enterprises have prospects for development in growing demand for dairy products. However, their successful functioning largely depends on financial planning and effective use of resources. Therefore, financial stability is essential to the successful functioning of milk processing enterprises. Investments in modern equipment and technologies also play a vital role in developing dairy enterprises, thanks to which enterprises increase productivity, reduce costs, and improve product quality. The structure of financial resources of milk processing enterprises is considered, and the factors determining the formation and functioning of financial support in conditions of instability and market changes are determined. In this regard, complexity and systematicity are leading characteristics of financial potential. It is noted that effective financial management, which includes operational accounting, budget planning, cost control, and rational use of resources, is an essential component of the development of milk processing enterprises. Keywords: enterprise, economic development, dairy industry, financial resources, development potential.

One-leg standing time is a simple measure for loss of skeletal muscle mass and fat deposition in muscle: the J-SHIPP study

BackgroundsOne-leg standing time (OLST) has been frequently used physical performance measure; however, what muscular characteristics OLST represents remains uncertain.AimThis cross-sectional study aimed to investigate the association between OLST and muscle characteristics to clarify the possibility of using OLST as a physical performance measure.MethodsStudy participants comprised 1144 older adults aged 65 years or older. Computed tomography images provided mid-thigh skeletal muscle cross-sectional area and mean attenuation value. OLST was measured for a maximum of 60 s. Static postural instability was assessed using a posturography.ResultsA frequency of OLST < 20 s was increased by quartiles of muscle cross-sectional area (Q1: 33.6, Q2: 12.8, Q3: 13.6, Q4: 11.9%, P < 0.001) and mean attenuation value (Q1: 32.3, Q2: 21.7, Q3: 14.3, Q4: 7.7%, P < 0.001). Results of the multinomial regression analysis indicated that muscle cross-sectional area and mean attenuation value were independently associated with an OLST of less than 20 s. The crude odds ratio of OLST less than 20 s for the lowest quartiles of both cross-sectional area and mean attenuation value was 4.19 (95% CI: 3.01 − 5.84). The cross-sectional area of muscles with greater fat deposition was inversely associated with OLST, while that with smaller fat deposition showed a positive association with OLST, indicating why mean attenuation value and cross-sectional area were independently associated with OLST. No clear relationship was observed with static postural instability.ConclusionOLST was a simply measurable quantifiable physical measure representing the loss of muscle mass and quality in older adults.

The gap-size influence on the excitation of magnetorotational instability in cylindricTaylor–Couette flows

The excitation conditions of the magnetorotational instability (MRI) are studied for axially unbounded Taylor–Couette (TC) flows of various gap widths between the cylinders. The cylinders are considered as made from both perfect-conducting or insulating material and the conducting fluid with a finite but small magnetic Prandtl number rotates with a quasi-Keplerian velocity profile. The solutions are optimized with respect to the wavenumber and the Reynolds number of the rotation of the inner cylinder. For the axisymmetric modes, we find the critical Lundquist number of the applied axial magnetic field: the lower, the wider the gap between the cylinders. A similar result is obtained for the induced cell structure: the wider the gap, the more spherical the cells are. The marginal rotation rate of the inner cylinder – for a fixed size of the outer cylinder – always possesses a minimum for not too wide and not too narrow gap widths. For perfect-conducting walls the minimum lies at $r_{{\rm in}}\simeq 0.4$ , where $r_{{\rm in}}$ is the ratio of the radii of the two rotating cylinders. The lowest magnetic field amplitudes to excite the instability are required for TC flows between perfect-conducting cylinders with gaps corresponding to $r_{{\rm in}}\simeq ~0.2$ . For even wider and also for very thin gaps the needed magnetic fields and rotation frequencies are shown to become rather huge. Also the non-axisymmetric modes with $|m|=1$ have been considered. Their excitation generally requires stronger magnetic fields and higher magnetic Reynolds numbers in comparison with those for the axisymmetric modes. If TC experiments with too slow rotation for the applied magnetic fields yield unstable modes of any azimuthal symmetry, such as the currently reported Princeton experiment (Wang et al., Phys. Rev. Lett., vol. 129, 115001), then also other players, including axial boundary effects, than the MRI-typical linear combination of current-free fields and differential rotation should be in the game.

Turing Instabilities are Not Enough to Ensure Pattern Formation.

Symmetry-breaking instabilities play an important role in understanding the mechanisms underlying the diversity of patterns observed in nature, such as in Turing's reaction-diffusion theory, which connects cellular signalling and transport with the development of growth and form. Extensive literature focuses on the linear stability analysis of homogeneous equilibria in these systems, culminating in a set of conditions for transport-driven instabilities that are commonly presumed to initiate self-organisation. We demonstrate that a selection of simple, canonical transport models with only mild multistable non-linearities can satisfy the Turing instability conditions while also robustly exhibiting only transient patterns. Hence, a Turing-like instability is insufficient for the existence of a patterned state. While it is known that linear theory can fail to predict the formation of patterns, we demonstrate that such failures can appear robustly in systems with multiple stable homogeneous equilibria. Given that biological systems such as gene regulatory networks and spatially distributed ecosystems often exhibit a high degree of multistability and nonlinearity, this raises important questions of how to analyse prospective mechanisms for self-organisation.

ДОЦІЛЬНІСТЬ РЕГУЛЮВАННЯ ГОМЕОСТАЗУ СОЦІАЛЬНО-ЕКОНОМІЧНОГО ВІДТОРГНЕННЯ В УМОВАХ ФІНАНСОВОЇ ТУРБУЛЕНТНОСТІ

The presented study contains the author's vision of the main aspects and approaches to the possibility and expediency of regulating homeostasis of socio-economic rejection in the conditions of post-war economic instability and financial turbulence. The purpose of the study is to determine the feasibility of regulating homeostasis of socio-economic rejection in the context of systematization of modern provisions and concerns of leading financiers regarding the spread of financial recession trends. The methodological basis of the study was scientific publications and monographs, articles of journals and materials of scientific and practical conferences. The research content of scientific periodicals was used during the study; comparative critical analysis of existing approaches and methods of analysis of financial stability and tax burden; Statistical methods of analysis. The main hypothesis of the study was to assume the possibility of leveling socio-economic rejection at enterprises by introducing the latest financial and economic technologies of digital transformation and restoration of Ukraine's production potential. Presenting main material. It has been proven that the disturbing momentum of rejection occurs at the enterprise daily and every hour, namely: the need for education, science increases, differentiation in the income of employees increases, the level of competitiveness of the enterprise's products is changing, a new product or technology that produces at least two consequences is formed. In the first case, fluctuation is suppressed and a new balance arises, and all the indignation energy inside the enterprise is absorbed by the dynamics of the individual preferences of the enterprise. In the second case, fluctuation energy does not dissolve in new passions of individuals, but on the contrary, it remains and even increases, ensuring the formation of interest of the enterprise as such. Originality and practical importance. Categorization of socio-economic rejection, where substantiated, is a key tool for avoiding socio-economic rejection –– socio-dynamic multiplier of economic growth of an enterprise, which functions in the form of interaction of three components: social effect, employees' inclination to constructive and collective and collective work; A set of formal and informal institutions that ensure a combination of socio-economic effect with the tendency of employees to constructive actions. Conclusions and prospects for further research. To support the homeostasis of the enterprise, it is proposed to introduce a mechanism of homeostat, which is an appropriate complex of enterprise management systems, taking into account the capabilities and needs of employees, which includes an ensemble of signaling and regulatory systems of the enterprise, which are self-regulating, where management is only an element, not a supervisor. It is proposed to create an entity entity in the form of a set of long -term partnerships with all "interested parties" of the enterprise

Microphysical mechanisms of wintertime postfrontal precipitation enhancement over the Australian Snowy Mountains

AbstractA heavy orographic precipitation event associated with the postfrontal sector of a midlatitude cyclone over the Australian Snowy Mountains (ASM) was analyzed using field observations and numerical simulations. This event, observed during a 2018 intensive field campaign, was of particular interest as three distinct precipitation episodes were identified within a prolonged postfrontal period. Deep mixed‐phase clouds (MPCs) characterized by cold cloud‐top temperatures (colder than −30°C) and the presence of updrafts extending 3.5–4.5 km above the boundary‐layer height, produced the three enhanced precipitation events over the windward slopes of the ASM. The presence of conditional instabilities and deep updrafts were also found in the sounding and Doppler velocity observations respectively, while the cloud radar observations show the deep MPCs with cloud tops reaching to 6–7 km a.s.l. Orographic convection invigoration was found to be the main mechanism producing the precipitation enhancement over the windward slopes and higher terrain. Using the Weather Research/Forecasting model, we analyzed the rates of microphysical processes to explicitly account for the enhancement of precipitation formation processes in these MPCs. This analysis showed that the precipitation formation processes were further enhanced through depositional and riming growth of ice‐phase hydrometeors during the three precipitation events. Deposition is simulated at higher levels (above the −15°C level) and most likely enabled by deep convective updrafts through the midtroposphere, whereas riming is stronger at lower levels (below −10°C level) due to the persistent production of feeder supercooled liquid water clouds sustained by the orographic lifting.

Orbital instability of periodic waves for scalar viscous balance laws

The purpose of this paper is to prove that, for a large class of nonlinear evolution equations known as scalar viscous balance laws, the spectral (linear) instability condition of periodic traveling wave solutions implies their orbital (nonlinear) instability in appropriate periodic Sobolev spaces. The analysis is based on the well-posedness theory, the smoothness of the data-solution map, and an abstract result of instability of equilibria under nonlinear iterations. The resulting instability criterion is applied to two families of periodic waves. The first family consists of small amplitude waves with finite fundamental period which emerge from a local Hopf bifurcation around a critical value of the velocity. The second family comprises arbitrarily large period waves which arise from a homoclinic (global) bifurcation and tend to a limiting traveling pulse when their fundamental period tends to infinity. In the case of both families, the criterion is applied to conclude their orbital instability under the flow of the nonlinear viscous balance law in periodic Sobolev spaces with same period as the fundamental period of the wave.

Taxis-Driven Pattern Formation in Tri-Trophic Food Chain Model with Omnivory

The spatiotemporal dynamics of a three-component model of a food web are considered. The model describes the interactions between populations of resources, prey, and predators that consume both species. It assumes that the predator responds to the spatial change in the resource and prey densities by occupying areas where species density is higher (prey-taxis) and that the prey population avoids areas with a high predator density (predator-taxis). This work studies the conditions for the taxis-driven instability leading to the emergence of stationary patterns resulting from Turing instability and autowaves caused by wave instability. The existence of nonconstant positive steady states for the system is assessed through a rigorous bifurcation analysis. Meanwhile, the conditions for the existence of both types of instabilities are obtained by linear stability analysis. It is shown that the presence of cross-diffusion in the system supports the formation of spatially heterogeneous patterns. For low values of the resource-tactic and predator-tactic coefficients, Turing and wave instabilities coexist. The system undergoes only Turing instability for high levels of these parameters.

New slope inequalities for families of complete intersections

We prove f -positivity of \mathcal{O}_X(1) for arbitrary dimensional fibrations over curves f\colon X\to B whose general fibre is a complete intersection. In the special case where the family is a global complete intersection, we prove numerical sufficient and necessary conditions for f -positivity of powers of \mathcal{O}_X(1) and for the relative canonical sheaf. From these results we also derive a Chow instability condition for the fibres of relative complete intersections in the projective bundle of a \mu -unstable bundle.

Influence of Geomagnetic Storms on Power System Static Voltage Security

The adverse effects of geomagnetic storms on power systems have been confirmed by numerous examples and observations. However, there remains a dearth of research on the quantitative assessment of the safety risks of a system under extreme geomagnetic storm conditions. Accordingly, in this study, we developed a risk assessment model for magnetic storm disasters based on the static voltage security region theory from the global perspective of power grid security. First, we determined the boundary shape of the static security region of a system under magnetic storm conditions and analyzed its influence on the voltage stability of the system from a regional perspective. Subsequently, a static safe-distance index was proposed to characterize the influence of a magnetic storm disaster on the system voltage. Considering the uncertainty in the injected power during a magnetic storm, we calculated the static voltage instability probability of the system. Through probability index analysis, a probabilistic safety assessment of the system under magnetic storm conditions was performed, and its overall static voltage safety level was measured. Finally, a simulation analysis based on the UIUC 150 node showed the proposed method to be reasonable and effective.

Cross-diffusion mediated Spatiotemporal patterns in a predator–prey system with hunting cooperation and fear effect

Cooperation during hunting is a common predation plan of action among several large predators to increase their biomass raising capturing potential which can also produce fear in the prey and dispersal-influenced pattern creation is also relevant from both a fundamental and an applied standpoint. Considering these, we present a modified Leslie–Gower predator–prey model incorporating fear, intra-specific competition and hunting cooperation of predators following Berec’s encounter-driven functional response in presence of cross-diffusion. In the non-spatial system, biologically feasible equilibria and their stability conditions are derived. Taking the level of fear as bifurcation parameter, occurrence of limit cycle via Hopf bifurcation and the stability of limit cycle computing Lyapunov coefficient are discussed. In diffusive model, spacial focus on Turing instability conditions and to determine the relevant intervals at which various patterns will begin to appear. In the two dimensional spatial domain, under Neumann boundary condition, various Turing patterns such as spot, stripe, mixture of spot and stripe, labyrinth patterns are emerged varying fear, hunting cooperation and cross-diffusion coefficient. Hopf–Turing region is also a centre for several complex patterns. The numerical simulations indicate that the patterns are in same or opposite phase according to the sign of cross-diffusion coefficient. Intra-specific competition among predators tend the system towards stability. Cross-diffusion causes a paradox to population density with raising fear and hunting cooperation.

Development of the Theory and Practice of Calculating the Cost of Logistics Services As an Element of Customs and Logistics Risk Management in International Supply Chains for Goods Containing Intellectual Property

In conditions of geopolitical instability, the introduction of a huge number of sanctions against our country, conducting foreign economic activity is becoming more and more difficult and expensive. One of the important stages in the international supply chain is customs logistics in terms of customs control, the passage of which is mostly assigned to the logistics operator (customs representative). Every second product today contains intellectual property, and customs authorities have a number of mechanisms to control this complex category of goods. The application by customs authorities of the customs control mechanisms provided for by the customs legislation of the EAEU affects the timing of the release of goods (suspension of the release of goods for 20 working days), as well as the final cost (accounting for license fees in the structure of the customs value of goods). The paper analyzes emerging customs and logistics risks in international supply chains of goods containing intellectual property. The key figure in the declaration of goods is, as a rule, the logistics operator, acting on behalf of and on behalf of the foreign trade participant. However, today the risks of a logistics operator are not taken into account when determining the cost of services for performing operations related to the customs declaration of goods containing intellectual property. The article structures emerging customs and logistics factors in international supply chains of goods containing intellectual property. For this purpose, based on the customs and logistics risks that arise for the logistics operator during the customs declaration of goods containing intellectual property, the consequences of the occurrence of the considered risks for him are determined. A methodology for calculating flexible tariffs for a logistics operator has been developed, including criteria for differentiating tariffs depending on external and internal factors, and correction factors have been proposed.
