Published: December 2024

The article discusses the results of a long-term bioindication study carried out in the period from 2017 to 2023 years to study the content of the amino acid proline in a biomass sample of background species of green spaces (introduced and native species), as the main biochemical marker of the state of the environment under conditions of a strong combination of stress factors. The bioindicators in the experiment were elements of green spaces in the administrative districts of the city of Bryansk: Sovetsky, Bezhitsky, Fokinsky, Volodarsky, as well as in the control - the village of Dobrun, Bryansk district: 14 species of angiosperms and gymnosperms were taken into account. The purpose of the work is to evaluate in the long term the change in the content of the amino acid proline as a biochemical marker of the state of the environment of a large city in the Non-Black Earth Region of the Russian Federation when diagnosing the biomass of background plants. The stability coefficient of dendroflora growing in 4 districts of Bryansk is presented, indicating the minimum and maximum values of amino acid cumulation by region and the air pollution index. The lowest value of the cumulation coefficient was calculated for the species: Pinus sylvestris L. (3,5-3,97), Picea abies L. (3,68-4,14), Picea pungens L. (3,77-4,28 ); highest value: Aesculus hippocastanum L. (6,17-6,59), Acer negundo L. (6,29-6,74), Syringa vulgaris L. (6,38-6,8). A series of sensitivity of woody plants to air pollution has been compiled according to the degree of reduction in proline content: Pinus sylvestris < Picea abies L. < Picea pungens L. < Thuja occidentalis L. < Quercus robur < Betula pendula < Salix triandra < Tilia cordata < Sorbus aucuparia < Robinia pseudoacacia < Acer platanoides < Acer negundo< Aesculus hippocastanum < Syringa vulgaris. It has been established that the concentration of proline is related by a regression relationship to the calculated air pollution index: with the growth of aerotechnogenic pollution, the content of the amino acid increases.

Published: December 2024

Background. Apricot is one of the most popular fruit crops in the world. Central Russia belongs to the moderately cold climatic subzone of climatic zone II with the sum of effective temperatures of 1000-2200ºС. Therefore, the biological characteristics of apricot varieties for this zone must correspond to the environmental conditions of the region. Studying the process of fruit ripening of winter-hardy apricot varieties can be useful when carrying out breeding work.
Purpose. To study the dynamics of the main physiological and biochemical parameters of leaves and fruits of apricot varieties of Moscow selection.
Material and methods. The object of the study was the fruits and leaves of apricot varieties selected by GBS RAS (Moscow) during the formation and ripening of fruits. During the period of fruit formation (June-August), the content of mono- and polysaccharides, photosynthetic pigments - chlorophylls and carotenoids, flavonoids, as well as the HPLC method of some phenolcarboxylic acids was determined in the samples using the spectrophotometric method according to generally accepted methods. Morphometric indicators were also recorded: weight and diameter of the fruit, leaf area.
Results. Varietal specificity has been established based on the studied biochemical and morphometric parameters of leaves and fruits. The largest fruits were in the Tsarsky variety, the minimum size in the selected Zachatievsky variety. A similar picture was observed for fruit diameter and leaf area. The level of chlorophylls and carotenoids in the leaves remained stable throughout the entire study period in the Tsarsky variety, the best in terms of fruit ripening and taste. In the leaves of the Tsarsky variety in June and July, the level of carotenoids was ~35% higher than in other samples. No significant varietal differences were found in the content and ratio of mono- and polysaccharides. A decrease in the level of phenols and an increase in the content of polysaccharides and carotenoids contributed to the formation of the sweet-sour taste and color of the fruit. The presence of phenols involved in the activation of protective mechanisms at all stages of fruit formation and development apparently makes it possible to overcome the negative effects of weather conditions. According to biochemical and organoleptic indicators, early ripening varieties Tsarsky and Lel are distinguished.
Conclusion. The dynamics of the biochemical composition of leaves and fruits of winter-hardy apricot varieties of Moscow selection during the process of fruit formation was studied for the first time. Such data may help identify markers for selecting breeding material with adaptive capabilities to biotic and abiotic stresses in central Russia.

Frame by Fame: Content Creation on Short Video-Format Platforms
Authors: Deshmane Abhishek , Barriola Xabier 
Published: December 2024

Problem definition: Short video format platforms like NetEase and TikTok are attention economies that host user-generated content, in the form of combined video and audio elements, and operate on principles of network virality. This study explores user content creation strategies by focusing on decisions around content release frequency and the incorporation of adopted content in newly generated creations. Methodology/results: We theoretically explore the role of the following three mechanisms influencing these decisions: (a) social hierarchies in the platform’s network structure, (b) virality of content on the platform, and (c) algorithmic interventions through the ranking of content recommendations. To empirically study these relationships, we use a detailed log of user activity on NetEase Cloud Village registered during the month of November 2019 and carry out regression-based analyses. We find that high-status users, measured through their follower count, adapt their content release frequency strategically, slowing down after successful content to avoid dilution of potential virality. We also observe that high-status users generally deviate from prevailing viral trends in their content creation. However, following exceptionally successful releases, they tend to conform more to viral content, suggesting a risk-averse approach. Finally, contrary to algorithm aversion, users prefer content recommended by the platform. However, high-status users disregard algorithms to retain agency in decision making. Managerial implications: Our findings provide a holistic understanding of the content creation process and suggest that platforms could strategically adjust algorithmic ranking policies to foster content creation diversity while catering to the preferences of users with different status levels.

The Restaurant Meal Delivery Problem with Ghost Kitchens
Authors: Neria Gal , Hildebrandt Florentin D. , Tzur Michal , Ulmer Marlin W. 
Published: December 2024

Restaurant meal delivery has been rapidly growing in the last few years. The main operational challenges are the temporally and spatially dispersed stochastic demand that arrives from customers all over town as well as the customers’ expectation of timely and fresh delivery. To overcome these challenges, a new business concept emerged: ghost kitchens. This concept proposes synchronized food preparation of several restaurants in a central facility. Ghost kitchens can bring several advantages, such as fresher food because of the synchronization of food preparation and delivery and less delay because of the consolidated delivery of orders. Exploiting these advantages requires effective operational strategies for the dynamic scheduling of food preparation and delivery. The goal of this paper is providing these strategies and investigating the value of ghost kitchens. We model the problem as a sequential decision process. For the complex decision space of scheduling order preparations, consolidating orders to trips, and scheduling trip departures, we propose a large neighborhood search (LNS) procedure based on partial decisions and driven by analytical properties. Within the LNS, decisions are evaluated via a value function approximation, enabling anticipatory and real-time decision making. In a comprehensive computational study, we demonstrate the effectiveness of our method compared with benchmark policies and highlight the advantages of ghost kitchens compared with conventional meal delivery.

Published: December 2024

Aims/Background The prevalence of postpartum fatigue among primipara is high in China, which seriously affects women’s subsequent physical and mental recovery. In order to deeply understand this phenomenon, domestic scholars began to conduct research on postpartum fatigue from the aspects of assessment tools and intervention measures. This study aims to investigate postpartum fatigue in primiparous women and its association with family functioning and social support, providing valuable insights for improving the condition in this population. Methods Primiparous women from February 2023 to March 2024 were selected as participants. Baseline demographic information was collected, and postpartum fatigue levels were assessed using Postpartum Fatigue Scale (PFS) at 7 days postpartum. Social support was evaluated with Postpartum Social Support Scale, and maternal role adaptation was assessed using Maternal Role Adaptation Questionnaire (MRAQ). Pearson correlation analysis was conducted to examine the relationship between postpartum fatigue levels, role adaptation, and social support. Results A total of 210 survey questionnaires were distributed; following which, 201 valid questionnaires were received. The total PFS score was 13.93 ± 4.53 points. Among the participants, 50 cases (24.87%) experienced no fatigue, 58 cases (28.86%) with mild fatigue, 78 cases (38.81%) with moderate fatigue, and 15 cases (7.46%) with severe fatigue. There were statistically significant differences in all dimensions and total scores of the Postpartum Social Support Level Scale for primiparas with different levels of postpartum fatigue (p < 0.001), with those facing severe fatigue reporting significantly lower level of social support. There were statistically significant differences in the comparison of each dimension and total score of the role adaptation scale for primiparas with different levels of postpartum fatigue (p < 0.001). The degree of role adaptation in patients with severe fatigue was significantly lower. The PFS score of primiparas was negatively correlated with the level of social support and role adaptation (r = –0.693, r = –0.735, p < 0.001). Conclusion The majority of primiparous women experience varying degrees of postpartum fatigue at 7 days postpartum. Poor newborn health, artificial feeding, and nighttime feeding frequency ≥4 times per night can exacerbate postpartum fatigue. Good social support and role adaptation are beneficial in alleviating postpartum fatigue. Strengthening social support and role adaptation can help reduce postpartum fatigue levels in primiparous women.
Effect of stimulus size on chromatic discrimination
Authors: Danilova M. V. , Mollon J. D. 
Published: December 2024

In psychophysical experiments, discrimination thresholds were measured in different directions around points in the MacLeod–Boynton chromaticity diagram, while the eye was maintained in a state of constant adaptation to a metamer of D65. A spatial forced-choice procedure was used: a brief (150 ms) disk divided into four sectors was presented, and the observers’ task was to detect the sector that differed from the other three. The diameter of the test disk varied from 32 min to 2.4∘ of visual angle. Sensitivity was probed at several different referent positions in the chromaticity diagram, including the adapting chromaticity. The data for each referent were fitted with ellipses. In the case of the largest test size (2.4∘ diameter), ellipses were predominantly oriented so that their longer axis was aligned with the line connecting the center of the ellipse to the chromaticity of D65 (the adaptation point). Along such radial lines, colorimetric purity varies, and the orientation of the ellipses reflects reduced sensitivity to saturation differences compared to hue differences. With decreasing test size, the ellipses change their orientation so that their longer axis is rotated toward a tritan direction, and the detection of changes in chromaticity depends primarily on the activity of long- and middle-wave cones. However, these general principles must be modified in several ways according to the region of the chromaticity diagram that is being probed.

Published: December 2024

Subject of study. This study focuses on the acquisition,
processing, and interpretation methods and algorithms for spectral
images aimed at evaluating surface defects in fruits. Aim of study. The aim of this study is to
develop a method for assessing fruit preservation techniques based on
the automatic detection and quantitative evaluation of surface defects
using imaging spectroscopy. Method.
Spectral images were acquired using an acousto-optical imaging
spectrometer with a spectral range of 450–850 nm and a bandwidth of
2.5 nm at a wavelength of 650 nm, with a 5 nm step. For processing the
spectral images, well-established operations and algorithms for data
enhancement and analysis were employed. These included correction for
uneven illumination, correction for spatial and spectral inhomogeneity
of the optical system’s transmittance coefficient, various image
filtering techniques, and threshold binarization. Object
classification was based on spectral features. The proposed approach
was tested in an experimental study that evaluated the effectiveness
of preservation techniques for peaches and nectarines using a
treatment that inhibits ethylene production. Main
results. A methodology for spectral image acquisition and
processing was developed, enabling the automated detection and
quantification of surface defects on fruits. An evaluative parameter,
defined as the ratio of the defect area to the total surface area of
the fruit, was introduced. This parameter allowed for comparison under
different experimental conditions. The approving of the approach
demonstrated the feasibility of automated defect size determination on
fruit surfaces, with a relative error of 11%. Practical significance. The developed data processing
algorithms enable regular diagnostics of samples and early
identification of defects. The methodology for data acquisition and
processing can be extended to devices based on other physical
principles for obtaining the spatial distribution of spectral
characteristics of objects. This solution complements existing methods
for assessing fruit preservation techniques and contributes to the
integration of imaging spectrometers into routine practices within the
agro-industrial sector.

Published: December 2024

Subject of study. The effect of increased pressure in the flow cell of a multichannel spectrophotometer on the redistribution of radiation power across fiber-optic channels is analyzed. Aim of study. The study aims to develop a method and algorithm to compensate for the additional error in measuring the transmittance of a substance in a multichannel spectrophotometer system caused by changes in pressure within the flow cell. Method. A model was developed in the Comsol Multiphysics environment, based on the classical theory of elasticity, to describe the mechanical stresses and changes in the deformation profile of the optical windows in a flow cell for various increased pressure levels. Numerical modeling of the deformation profile of optical windows in the flow cell was conducted for different values of increased pressure. These results were subsequently used to calculate the deviation of the wavefront of transmitted radiation and determine the irradiance distribution on the end face of the fiber-optic bundle. Additionally, a simulation using the Zemax Optic Studio software package was performed to justify the use of either an afocal or focusing optical system in the spectrophotometer. Main results. The study demonstrates that increased pressure within the flow cell affects the resulting optical power in the channels of a fiber-optic multichannel spectrophotometer. At a pressure of 100 MPa, the calculated transmittance measurement error for an afocal forming system and a seven-channel fiber-optic bundle reaches 28%. A matrix of correction coefficients and a calibration algorithm were proposed to account for the increased pressure in the flow cell system and the refractive index of the analyte. Practical significance. The findings highlight the necessity of considering the effects of increased pressure in in-line systems. A matrix of calibration coefficients and a calibration algorithm for multichannel spectrophotometers are proposed to enhance the measurement accuracy under variable pressure conditions.
