This article is about numerical control of HIV propagation. The contribution of the article is threefold: first, a novel model of HIV propagation is proposed; second, the methods from numerical optimal control are successfully applied to the developed model to compute optimal control profiles; finally, the computed results are applied to the real problem yielding important and practically relevant results.

Theoretically, this work belongs to a fairly broad class of articles and books devoted to solving
control problems for dynamic objects with constraints on control actions and the Bolza functional.
The necessary conditions for the existence of optimal controls for a terminal differential game are
described by a two-point boundary value problem and the condition for choosing the ...

This article demonstrates how the concept of preventable mortality can be used to develop mortality reduction measures using cardiovascular disease (CVD) as an example. The measures are structured according to Donabedian model. A Russian methodology for determining preventable mortality, based on international approaches and adapted to Russian healthcare system, was used. In collaboration with federal ...

The problem of a zero-sum differential stabilization game with a quadratic performance functional is considered. The control plant, subject to uncontrollable disturbances, is described by a nonlinear ordinary differential
equation. It is known that the synthesis of optimal feedback controls leads to the need to solve a scalar Bellman-Isaacs partial differential equation at the system's operating speed. An algebraic ...

The optimal control of a system’s final state is a fundamental problem that constitutes the core of many optimization tasks. Such problems involve describing the dynamic object, specifying constraints on controls and states, and defining a quality functional, typically a Bolza functional. The necessary optimality conditions for synthesizing the corresponding controls are written as a canonical Euler–Lagrange system with specified ...

Background
As set out in Sustainable Development Goal 3.3, the target date for ending the HIV epidemic as a public health threat is 2030. Therefore, there is a crucial need to evaluate current epidemiological trends and monitor global progress towards HIV incidence and mortality reduction goals. In this analysis, we assess the current burden of HIV ...

Introduction. In 2021, the results of the first large-scale prospective cohort study were published showing the negative impact of post-diagnosis smoking on the prognosis of non-small cell lung cancer (I-IIIа). The purpose of the study is to assess the possible benefits of postdiagnosis smoking cessation of patients with non-small cell lung cancer (NSLC) stage I–IIIa ...

The article shows that actual public expenditure in the period of rapid oil prices growth of the 2000s was
less than the optimal level in Russia. The macroeconomic model of Russian economy is the basis of current
research. The main mechanism of growth in an optimum scenario is associated with the scaling effect
of public expenditure, which increases ...

The article describes an interview analysis with one of the first people who was diagnosed with HIV infection in the Soviet Union. Based on the vocabularies of motive by C.W. Mills are proposed to distinguish between two types of social encounters’ accounts: justifications and excuses. The way of avoiding accounts of social encounters is specified. ...

In this paper algorithm of control synthesis for car active suspension with delays is examined. The problem is formulated in terms of differential games. External perturbation such as road surface unevenness is considered as actions of some opponent. The commonly known model of quarter car active suspension system will be expanded with delays under 0.5s ...

Migrants experience several challenges en route to or in their host country. Current legislation in Russia imposes a permanent ban on international migrants with HIV obtaining a residence permit in Russia. Using qualitative methodology, we conducted semi-structured interviews with 15 international migrants who have lived with HIV in Russia and 12 interviews with healthcare providers ...

This paper is devoted to general optimal control problems (OCPs) associated with a family of nonlinear continuous-time switched systems in the presence of some specific control constraints. The stepwise (fixed-level type) control restrictions we consider constitute a common class of admissible controls in many real-world engineering systems. Moreover, these control restrictions can also be interpreted ...

This paper proposes a new theoretic approach to a specific interaction of continuous and discrete dynamics in switched control systems known as a Zeno behaviour. We study executions of switched control systems with affine structure that admit infinitely many discrete transitions on a finite time interval. Although the real world processes do not present the ...

Building on previous work on the securitisation of HIV/AIDS, studies of framings, and the Copenhagen and Paris schools of security studies, this essay explores how policy framings of HIV/AIDS have shifted from the late Soviet period through to present-day Tajikistan. Pointing to both continuity and change, it shows how, under the influence of international actors ...

This article analyses how global governance frameworks and knowledge claims are
translated to fit local contexts. It specifically looks at harm reduction initiatives targeting
injection drug users utilising the case of Tajikistan. In the 1990s, this post–Soviet
Central Asian country became exposed to an inflow of cheap and easily available heroin
from Afghanistan. While Tajikistan mainly became a transit ...

The article deals with the ways Russian authorities have constructed the social problem of HIV/AIDS (human immunodeficiency virus/ acquired immune deficiency syndrome) in Russia. The statistical construction of HIV/AIDS includes data indicating the significant rise of HIV prevalence in Russia since 2000. The study focuses on what and how Russian authorities speak about HIV/AIDS, while ...
