The article provides a comparative analysis of the current practice of Russian organisations in the development and implementation of a balanced score-card. The reasons for low efficiency of the companies are described separately. The expediency of using a strategic management mechanism in the activities of the companies is substantiated in detail, and also, based on the application of tabular data, the scale of scientific research in the field of key performance indicators is indicated. The recommendations formulated by the authors reflect cause-and-effect relationships between customer requests and the needs of suppliers of goods and services. Particular attention is paid to assessing the potential effect of introducing the balanced scorecard into the activities of the Russian companies. As the article is written, patterns are revealed in the processes of implementation of personnel policies by the objects of research, formation of strategic goals, and realisation of a mechanism for disseminating information about the declared strategy among all official levels of the company. The authors of this work state detailed conclusions for each section indicating the detected motives for actions and predicting potential results. The algorithm for formulating recommendations for the development and implementation of the balanced scorecard identified at the beginning of the article finds its step-by-step development within the framework of the ongoing research and is accompanied by reasoned comments based both on previously published sources of information and on provisions proposed by the authors.- Book : (11)

Abstract
The study of hybrid nanofluids is significant in thermal management applications by optimizing heat transfer through pioneering materials, mainly the flow of sodium alginate-based hybrid nanofluids. This work addresses the demand for effective cooling solutions in a variety of industrial processes and uses the unique characteristics of non-Newtonian fluids and their inferences for rheological modeling and heat transform enhancement. Inspired by the progressive properties of the non-Newtonian Casson fluid and its applied significance in the rheological modeling and heat transfer characteristics of different dynamic fluids, there is limited knowledge of their response in the mixed convective flow, particularly when influenced by factors like thermal radiation, joule heating, and thermal relaxation time. The present study aims to investigate the heat transfer enhancement of the mixed convective flow of a sodium alginate-based hybrid nanofluid on an extending sheet concentrating on the interaction of different physical parameters that affect thermal performance. The physical phenomena are modeled in a nonlinear partial differential equation, which is then converted into ordinary differential equations with the help of suitable similarity variables. Tables and figures are constructed to show the behavior of the physical parameters involved in the momentum and temperature equations. Premilinary assumptions applied to the flow are electrically conducting, rotating, dissipative, and thermal boundary conditions. A semi-analytical approach homotopy analysis method is employed to obtain the solution of the problem. The outcome witnessed that the velocity profiles show a diminishing behavior through a magnetic parameter; however, the temperature profile shows an escalating behavior. Similarly, the thermal plot intensifies with the Eckert number and thermal radiation. In addition, the numerical data from the tables portrayed that the skin friction decreases with the Casson parameter and the rotation parameter; however, an improvement behavior is noticed in the Nusselt number through thermal radiation and thermal Biot number. From the numerical data, it is concluded that the hybrid nanofluid has superior heat transfer characteristics compared to nanofluid. The finding of this result has also been compared with available results in the literature through a comparative study.- Book : 14(1)

AbstractSkin flash is typically added to breast and chestwall plans to ensure robust target coverage in the presence of respiratory motion, anatomic changes, and small setup uncertainties. Adding skin flash in volumetric modulated arc therapy (VMAT) plans is an iterative and manual process. RapidArc dynamic (RAD) is a new solution that integrates a dynamic collimator and static‐gantry angle modulated ports directly into arc delivery. The automatic skin flash tool (ASF) allows users to automatically add skin flash directly within the optimizer. The user must select the thickness and Hounsfield Units (HUs) of the flash region, but the optimal values are not currently known. For 13 left‐ and right‐sided breast and chestwall patients, RAD plans were created with no skin flash and with ASF with thickness of 5 to 20 mm and HU of −500 to 0 HU. To assess plan quality, DVH metrics for planning target volume (PTV), heart, ipsilateral lung, contralateral lung, and contralateral breast were recorded. To assess plan robustness, the isocenter was shifted 5 mm, moving the target 5 mm anteriorly into the flash region. The changes in clinical target volume (CTV) D95% and D99% were recorded. A paired t‐test was used to determine if changes in plan quality or robustness were statistically significant (p ≤ 0.05). The addition of ≥ 7 mm of skin flash resulted in robust plans. Varying the HU did not affect robustness. Increasing the skin flash beyond 10 mm increased PTV V105%. This increase was much larger in the 0 HU plans than in the −350 HU plans. We therefore recommend using −350 HU and 7–10 mm of skin flash for anticipated inter‐ and intra‐fraction motion of 5 mm.- Book : ()

AbstractA theoretical framework is presented for temperature imaging from long‐wavelength infrared (LWIR) thermal radiation (e.g., 8–12 µm) through the end‐to‐end design of a metasurface‐optics frontend and a computational‐reconstruction backend. A new nonlinear reconstruction algorithm, “Planck regression”, is introduced to reconstruct the temperature map from a gray scale sensor image, even in the presence of severe chromatic aberration, by exploiting black body and optical physics particular to thermal imaging. This algorithm is combined with an end‐to‐end approach that optimizes manufacturable, single‐layer metasurfaces to yield the most accurate reconstruction. The designs demonstrate high‐quality, noise‐robust reconstructions of arbitrary temperature maps (including completely random images) in simulations of an ultra‐compact thermal‐imaging device. It is also shown that Planck regression is much more generalizable to arbitrary images than a straightforward neural‐network reconstruction, which requires a large training set of domain‐specific images.- Book : ()

We present seeing-limited ( arcsecond ) near-infrared integral field spectroscopy data of the type-2 quasars, QSO2s, SDSS J135646.10+102609.0 (J1356) and SDSS J143029.89+133912.1 (J1430, the Teacup), both belonging to the Quasar Feedback, QSOFEED, sample. The nuclear K-band spectra (1.95-2.45 m) of these radio-quiet QSO2s reveal several emission lines, indicative of the presence of a warm molecular gas reservoir (T≥1000 K). We measure nuclear masses of rm H_2 =5.9, 4.1, and $1.5 in the inner arcsecond diameter region of the Teacup (∼1.3 kpc), J1356 north (J1356N), and south nuclei (∼1.8 kpc), respectively. The total warm mass budget is ∼ 4.5 in the Teacup and ∼ 1.3 in J1356N, implying warm-to-cold molecular gas ratios of 10^-6. The warm molecular gas kinematics, traced with the and S(2) emission lines, is consistent with that of the cold molecular phase, traced by ALMA CO emission at higher angular resolution ( arcsecond and arcsecond ). In J1430, we detect the blue- and red-shifted sides of a compact warm molecular outflow extending up to 1.9 kpc and with velocities of 450 In J1356 only the red-shifted side is detected, with a radius of up to 2.0 kpc and velocity of 370 The outflow masses are 2.6 and 1.5times 10^3 for the Teacup and J1356N, and the warm-to-cold gas ratios in the outflows are 0.8 and 1 times implying that the cold molecular phase dominates the mass budget. We measure warm molecular mass outflow rates of 6.2 and 2.9 times 10^ for the Teacup and J1356N, which are approximately 0.001% of the total mass outflow rate (ionized + cold and warm molecular). We find an enhancement of velocity dispersion in the residual dispersion map of the Teacup, both along and perpendicular to the compact radio jet direction. This enhanced turbulence can be reproduced by simulations of jet-ISM interactions.- Book : ()
