Authors: Lin Qingze , Xie Huayou 
Published: January 2025

Abstract
In this article, by the use of nth derivative characterization, we obtain several some sufficient conditions for all solutions of the complex linear differential equation

$$ \begin{align*}f^{(n)}+A_{n-1}(z)f^{(n-1)}+\ldots+A_1(z)f'+A_0(z)f=A_n(z) \end{align*} $$

to lie in weighted Dirichlet spaces and derivative Hardy spaces, respectively, where

$A_i(z) (i=0,1,\ldots ,n)$

are analytic functions defined in the unit disc. This work continues the lines of the investigations by Heittokangas, et al. for growth estimates about the solutions of the above equation.

Published: January 2025

AbstractExisting spatial feature recognition and layout methods primarily identify spatial components manually, which is time‐consuming and inefficient, and the constraint relationship between objects in space can be difficult to observe. Consequently, this study introduces an advanced spatial feature recognition and layout methodology employing enhanced CenterNet and LSTM frameworks, which is bifurcated into two major components—first, HCenterNet‐based feature recognition enhances feature extraction through an attention mechanism and feature fusion technology, refining the identification of small targets within complex background areas; second, a GA‐BiLSTM‐based spatial layout model uses a bidirectional LSTM network optimized with a genetic algorithm (GA), aimed at fine‐tuning the network parameters to yield more accurate spatial layouts. Experiments verified that compared with the CenterNet model, the recognition performance of the proposed HCenterNet‐DIoU model improved by 7.44%. Moreover, the GA‐BiLSTM model improved the overall layout accuracy by 10.08% compared with the LSTM model. Time cost analysis also confirmed that the proposed model could meet the real‐time requirements.

Вступ. Сфера громадського здоров’я в Україні розвивається та проходить трансформаційні процесі, що направлені на оптимізацію її роботи, як в режимі повсякденної діяльності, так і в режимі надзвичайної ситуації, в тому числі з обов’язковою міжсекторальною співпрацею з Медичними силами Збройних сил України.
Метою проведеної роботи було виокремлення критеріїв відбору фахівців для формування груп швидкого реагування згідно міжнародного досвіду та сучасних тенденцій.
Матеріали та методи. Для проведення аналізу даної проблеми були взяті нормативно-правові акти чинного законодавства України; офіційні сайти національних та міжнародних організацій, що опікуються питаннями ХБРЯ загроз; документи ДУ «Центр громадського здоров’я Міністерства охорони здоров’я України».
Результати. Нами було виявлено, що в ряді країн (США, Китай, Англія, Нідерланди, Республіка Корея), сформовано медико-соціальні вимоги до фахівців, які в перспективі будуть працювати в вогнищі хімічного, біологічного чи радіаційного ураження. Серед найпоширеніших вимог до фахівців, що входять до складу групи швидкого реагування виділяють наступні: мобільність, своєчасність, експертність та злагодженість. Ще одним важливим аспектом є спроможність працювати в команді і вміти комунікувати з різними групами населення та профільними стейкхолдерами, такими як ДСНС, Медичними силами Збройних сил України, поліцією, СБУ тощо. Проаналізувавши літературні джерела та чинну нормативну базу України, були виділені наступні фактори, що матимуть вплив на здоров’я та працездатність фахівців груп швидкого реагування: фізичні (іонізуючого випромінювання), біологічних (збудники інфекційних захворювань); хімічних речовин, в тому числі їх сполуки та елементи; психофізіологічні показники (врівноваженость нервових процесів, концентрація уваги, показники короткочасної зорової пам’яті, швидкість сприйняття подразника, адаптації) та аналітичний тип мислення.
Висновки. В подальшому отримана інформація допоможе сформувати медичні та психофізіологічні вимоги до відбору персоналу груп швидкого реагування в Україні, що забезпечить раціональне використання людських та матеріальних ресурсів, а також зменшення санітарних втрат серед цивільного населення.

Published: January 2025

AbstractWhen considering the establishment of tree protection zones in construction, or in assessing relative damage to a tree for risk or penalty, it would be useful to have a method to predict total root area at some distance from the tree. With such a method, the arborist can assess the level of damage in comparison to some estimate of the total rather than from a loss of possible root zone space based on land area. We used a modification of the pipe model approach to estimate the root cross-sectional area at different distances from the tree as defined by the edge and center of the trunk. We discuss two early studies. The first considers root systems excavated from a limited set of 9 trees over 50 years post-establishment across 3 species. Trees were excavated and roots harvested, cataloged, and imaged for measurement at 1, 2 and 3 meters from the trunk edge of the respective tree. The second study considered 29 digitally mapped root systems ofFraxinus pennsylvanica‘Patmore’ 9 years post-transplant by developing code for a virtual dissection at specific distances from the tree trunk. The second study observed variability across a tightly defined set of trees. There was a weak relationship between root area at set distances by species, and we found 3 m was a useful distance in the first study. We have a long way to go in development before having a method as a tool for practice, but the approach may be useful with additional observation and study.
Improvements in aerosol layer height retrievals from TROPOMI oxygen A-band measurements by surface albedo fitting in optimal estimation

Published: January 2025

Abstract. The Aerosol Layer Height (ALH), from the Sentinel-5P/TROPOMI L2__AER_LH product, is based on an optimal estimation (OE) approach, fitting cloud-free measurements to synthetic reflectances in the strongest oxygen absorption band, provided by a neural network trained with high resolution simulated reflectances. The ALH has been continuously improved since its release in 2019, focusing especially on (bright) land surfaces, over which the ALH product showed underestimated aerosol layer heights (biased towards the surface). This paper describes the latest updates of the ALH product, that includes first the introduction of the Directional Lambertian-Equivalent Reflectance (DLER) climatology to improve the surface albedo characterisation over land. Second, the paper describes a further improvement, adding the surface albedo in the feature vector of the OE inversion, using the DLER as prior information. Using this approach, the retrievals over land largely match the retrievals over ocean, which have shown a good comparison with validation data since its release, most notably with CALIOP weighted extinction heights. The albedo is fitted for both land and ocean surfaces, but the implementation is different over land and ocean because of the large range of land surface albedos. Over land, the a priori surface albedo values are relaxed so the fitting procedure can incorporate the albedo effects in the retrieval over land. Over ocean, the retrievals are optimised by tuning the a priori error settings. The current implementation improves retrievals over land with about 1.5 times more converged results, and decreases land-ocean contrasts in the aerosol layer height retrievals. The average difference between CALIOP weighted extinction height decreased for selected cases from about −1.9 km to −0.9 km over land and from around −0.8 km to +0.1 km over ocean.

Published: January 2025

Augmented reality (AR) technology integrates virtual content into real environments using two main methods: marker-based and markerless tracking. Marker-based tracking relies on printed markers for object placement, while markerless uses environmental features for flexibility and accuracy. This research aims to evaluate the combined impact of environmental factors-distance, angle, and lighting-on these two methods. The Multimedia Development Life Cycle (MDLC) methodology was applied by testing 72 combinations of indicators: distance (5-120 cm), angle (30°, 45°, 90°), and light color (red, blue, green, yellow) using Xiaomi Note 8 and Google Pixel 4. Results show markerless tracking is superior in all conditions, achieving a 94.4% success rate on both devices. In contrast, marker-based tracking only achieved 72.2% (Xiaomi Note 8) and 77.8% (Google Pixel 4). Markerless tracking was optimally performed from 50 cm away and up close, while marker-based tracking degraded in performance at long distances and red lighting. Markerless tracking proved to be more reliable and consistent, suitable for dynamic and diverse environments, while marker-based methods remained relevant for short distances and controlled lighting. These findings provide guidance for AR developers in choosing a tracking methodology according to application needs.

Published: January 2025

Ограниченность мясных ресурсов в Российской Федерации стимулирует изучение и вовлечение в производство источников нетрадиционного мясного сырья, в частности оленины и конины. Оленину, как и мясо других диких животных, а также конину нельзя отнести к продуктам массового спроса. Блюда из нетрадиционного вида мяса – это, как правило, изысканные, ароматные и специфичные блюда и они часто представлены в меню ресторанов национальной кухни и специализированных заведений. В бурят-монгольской кухне известны блюда из мяса яка, лошади, косули, сайгака, козла, лося, изюбра и др. В статье приведены сведения по пищевой и биологической ценности мяса, по функционально-технологическим свойствам мясных систем. Представлена рецептура кулинарного изделия из оленины с гарниром и соусом из экологически чистого местного продовольственного сырья. Учитывая большой спектр полезных свойств уникальной ягодной культуры, дикороса региона, для приготовления соуса была выбрана облепиха. Оригинальным кулинарным решением является подача к оленине зернового продукта (замбаа), приготовленного на основе ячменной муки. Установлено, что благодаря высокому содержанию полезных веществ и низкой калорийности кулинарное изделие идеально подходит для меню спортсменов и людей, стремящихся к здоровому образу жизни, а также детей, пожилых людей и представителей вредных профессий.
The limited meat resources in the Russian Federation stimulate the study and involvement in the production of sources of non-traditional meat raw materials, in particular venison and horse meat. Venison, like meat and other wild animals, as well as horse meat cannot be classified as mass-market products. Dishes from an unconventional type of meat are, as a rule, refined, flavorful and specific, and they are often presented in the menus of restaurants of national cuisine and specialized establishments. In Buryat-Mongolian cuisine, dishes from yak, horse, roe deer, saiga, goat, elk, izyubr, etc. are known. The article provides information on the nutritional and biological value of meat, on the functional and technological properties of meat systems. The recipe of a venison culinary product with a side dish and sauce made from environmentally friendly local food raw materials is presented. Taking into account the wide range of useful properties of the unique berry culture, wild plants of the region, sea buckthorn was chosen for the preparation of the sauce. An original culinary solution is to serve a grain product (zambaa) to venison, prepared on the basis of barley flour. It has been established that due to the high content of nutrients and low calorie content, the culinary product is ideal for the menu of athletes and people striving for a healthy lifestyle, as well as children, the elderly and representatives of harmful professions.
