Restricted Bargaining Sets in a Club Economy
Authors: Bhowmik Anuj , Saha Sandipan 
Published: January 2025

Abstract
The core as a solution concept captures the set of allocations against which no objection exists by any coalition of agents. However, Aumann and Maschler (1961. The Bargaining Set for Cooperative Games. Princeton Univ NJ) emphasized that the objection mechanism does not talk about repercussions from agents and thus introduced the bargaining set. Vind (1992. “Two Characterizations of Bargaining Sets.” Journal of Mathematical Economics 21: 89–97) later introduced the notion of a global bargaining set. In this paper, we consider a club economy proposed by Ellickson et al. (1999. “Clubs and the Market.” Econometrica 67: 1185–217) where club goods are consumed parallel to private goods to capture the social aspects of consumption. We introduce the global bargaining set for our club economy and provide characterizations of it in terms of the size of the (counter-) objecting coalitions thereby extending the works of Schjødt and Sloth (1994. “Bargaining Sets with Small Coalitions.” International Journal of Game Theory 23: 49–55) and Hervés-Estévez and Moreno-García (2015. “On Restricted Bargaining Sets.” International Journal of Game Theory 44: 631–45). In the process, we obtain Schmeidler’s (1972. “A Remark on the Core of an Atomless Economy.” Econometrica 40: 579) and Vind’s (1972. “A Third Remark on the Core of an Atomless Economy.” Econometrica 40: 585) theorem for atomless club economies as simple corollaries. We provide further interpretations of the global bargaining set in terms of approximately robustly efficient states, a notion familiarised by Bhowmik and Kaur (2023. “Competitive Equilibria and Robust Efficiency with Club Goods.” Journal of Mathematical Economics 108: 102876) for club economies.

Abstract

Objectives
This study reported a large cohort of fetal blood analysis of various hemoglobinopathies.

Methods
A total of 371 fetal blood specimens were recruited. Complete blood count and hemoglobin (Hb) analysis using capillary electrophoresis were performed. Genotypes were defined by DNA analysis.

Results
Among 371 fetuses, 36 were non-thalassemic and 29 thalassemia genotypes were identified in the remaining 335 fetuses. Fetuses with β-thalassemia and Hb E traits, homozygous Hb E, and Hb E-β0-thalassemia had similar hematological parameters as those of non-thalassemic. However, the levels of Hb A in β-thalassemia and Hb E traits were approximately half of that observed in the non-thalassemic fetuses. As for Hb E, fetuses with a single copy of the βE-globin gene in the Hb E trait and Hb E-β0-thalassemia had lower Hb E levels as compared to that of the homozygous Hb E. For α-thalassemia, fetuses with one or two α-globin gene defects had small changes in hematological parameters, but variable Hb Bart’s levels were observed. Fetuses with Hb H and Hb H-CS diseases had moderate anemia, whereas those with homozygous Hb CS and Hb Bart’s hydrops fetalis had severe anemia. Identification of the fetuses with Hb Bart’s hydrops fetalis with various genetic interactions allows the exact re-location of electrophoretic mobilities of various embryonic Hbs.

Conclusions
This study confirmed the genetic heterogeneity of hemoglobinopathies among the fetuses and fetal blood analysis are useful for presumptive diagnosis of hemoglobinopathies. The results should facilitate a prevention and control program of hemoglobinopathies in the region.

Published: January 2025

Abstract
The EquiLing project aims at contributing to sociolinguistic justice by understanding language-mediated social inequalities and facilitating the conditions through which to challenge and transform these situations. In order to do so and following a Freirean approach and a Participatory Action Research methodology, we created conscientization spaces in two university sites in Bilbao and Madrid. In these conscientization spaces, researchers and students (or co-participants, as we term them here) engaged collaboratively in group dynamics to develop critical sociolinguistic awareness and foster transformative actions to challenge the sociolinguistic inequalities within each context. Students, when sharing these experiences, often evoked the external spaces they transit through in their daily lives, in which they faced situations that show lack of recognition, unequal distribution of resources and/or participation. Space appeared as a key element in the articulation of their narratives and experiences due to it usually being configured and constructed through hegemonic (in our case, sociolinguistic) ideologies and practices, which can leave speakers falling outside this normativity in situations of sociolinguistic injustice. In reaction to this, in our conscientization spaces, we (researchers and co-participants) have challenged these dynamics interactionally in joint reflection and practice by cultivating a safer space. In this sense, we have tried to foster counter-hegemonic practices in our spaces, facilitating in some cases a bridge to other spaces. This has shown that space is a central element in the configuration of a sociolinguistic order and that it is dynamic, socially constructed, and in continuous transformation, which also creates possibilities for resistance.

Abstract

Objectives
Childhood obesity is thought to influence pubertal development, according to observational studies. However, the exact causal relationship remains unclear due to the complexity of factors affecting pubertal development.

Methods
To explore the association between exposure (childhood obesity) and outcome (delayed puberty, height), we utilized various methods, including inverse-variance weighted (IVW), weighted median, weighted mode, and MR Egger regression. Additionally, sensitivity analyses were conducted using MR-Egger, MR-PRESSO, Cochran’s Q, and leave-one-out techniques to ensure the robustness of the results. Additionally, reverse MR analysis was conducted to explore potential reverse causation.

Results
The IVW analysis revealed no significant genetic causal link between childhood obesity and delayed puberty or height (all P>0.05). In the reverse analysis, height had a causal association with childhood obesity (OR=0.85, 95 % CI=0.76–0.96). The Cochran’s Q test highlighted heterogeneity in the results concerning childhood obesity and height (p<0.05). But the MR-Egger intercept and MR-PRESSO test confirmed no impact the results pleiotropic bias, supported by leave-one-out sensitivity analysis.

Conclusions
Our study found no significant genetic causal association between childhood obesity and delayed puberty or height. However, height was causally associated with childhood obesity. Future research should utilize advanced analytical methods to better understand the determinants of pubertal development.

Abstract
Metalenses, with their compact form factor and unique optical capabilities, hold tremendous potential for advancing computer vision applications. In this work, we propose a high-resolution, large field-of-view (FOV) metalens intelligent recognition system, combining the latest YOLO framework, aimed at supporting a range of vision tasks. Specifically, we demonstrate its effectiveness in scanning, pose recognition, and object classification. The metalens we designed to achieve a 100° FOV while operating near the diffraction limit, as confirmed by experimental results. Moreover, the metalenses weigh only 0.1 g and occupy a compact volume of 0.04 cm3, effectively addressing the bulkiness of conventional lenses and overcoming the limitations of traditional metalens in spatial frequency transmission. This work highlights the transformative potential of metalenses in the field of computer vision, The integration of metalenses with computer vision opens exciting possibilities for next-generation imaging systems, offering both enhanced functionality and unprecedented miniaturization.

Abstract
Analytical chemistry research has shifted towards environmentally friendly substitutes that reduce waste and avoid hazardous substances. These efforts align with broader environmental goals and inspire sustainable and responsible science. The objective of this work is to develop and validate an analytical method and verify its greenness using specific tools, including analytical GREEnness (AGREE), analytical greenness metric for sample preparation (AGREEprep), green analytical procedure index, complex green analytical procedure index, analytical Eco-Scale, analytical method volume intensity, analytical method greenness score, and HPLC-EAT (Environmental Assessment Tool). Effective treatment of chronic cough relies heavily on adequately utilizing salbutamol (SAL) and guaifenesin (GUA) in the presence of sodium benzoate (SOB) preservative. The isocratic elution mode used the Zorbax Eclipse Plus C18 column (15 cm × 4.6 mm, 3.5 µm). It could move 1.5 mL·min−1, hold 50 µL, have a column temperature of 30°C, and have an autosampler temperature of 5°C. It could detect UV light at 276 nm and had a mobile phase of 80:20 v/v buffer solution and acetonitrile. We have successfully established highly accurate calibration curves for the three components SAL, GUA, and SOB within the optimal range of 2–50 µg·mL−1. The coefficient of correlation (r) for these curves was at an impressive 0.9999 for SAL and GUA, while it was 0.9998 for SOB. The recovery values were 100.15%, 100.47%, and 100.92% for SAL, GUA, and SOB, respectively. The selectivity and sensitivity to the ingredients were confirmed according to the International Council for Harmonisation guidelines, as no interference occurred from any of the used sample components. We implemented Six Sigma, resulting in precision and productivity.
KV1 channels enable myelinated axons to transmit spikes reliably without spiking ectopically

Published: January 2025

Action potentials (spikes) are regenerated at each node of Ranvier during saltatory transmission along a myelinated axon. The high density of voltage-gated sodium channels required by nodes to reliably transmit spikes increases the risk of ectopic spike generation in the axon. Here we show that ectopic spiking is avoided because KV1 channels prevent nodes from responding to slow depolarization; instead, axons respond selectively to rapid depolarization because KV1 channels implement a high-pass filter. To characterize this filter, we compared spike initiation properties in the soma and axon of CA1 pyramidal neurons from mice of both sexes, using spatially restricted photoactivation of channelrhodopsin-2 (ChR2) to evoke spikes in either region while simultaneously recording at the soma. Somatic photostimulation evoked repetitive spiking whereas axonal photostimulation evoked transient spiking. Blocking KV1 channels converted the axon photostimulation response to repetitive spiking and encouraged spontaneous ectopic spike initiation in the axon. According to computational modeling, the high-pass filter implemented by KV1 channels matches the axial current waveform associated with saltatory conduction, enabling axons to faithfully transmit digital signals by maximizing their signal-to-noise ratio for this task. Specifically, a node generates a single spike only when rapidly depolarized, which is precisely what occurs during saltatory conduction when a pulse of axial current (triggered by a spike occurring at the upstream node) reaches the next node. The soma and axon use distinct spike initiation mechanisms (filters) appropriate for the task required of each region, namely analog-to-digital transduction in the soma vs. digital signal transmission in the axon.Significance statementNeurons use action potentials, or spikes, to transmit information reliably over long distances. Spikes can be initiated through different dynamical mechanisms depending on the types of ion channels involved. The input required to evoke spikes differs depending on spike initiation dynamics. Using targeted optogenetic stimulation to evoke spikes in different subcellular compartments, we show that the soma and axon of pyramidal neurons use distinct spike initiation mechanisms suited to the distinct role of each compartment. Specifically, the soma uses a low-pass filter supporting analog-to-digital transduction whereas the axon uses KV1 channels to implement a high-pass filter seemingly optimized for transmitting spikes. Importantly, the high-pass filter prevents the axon from generating ectopic spikes if slowly depolarized.
Downmodulation of potassium conductances induces epileptic seizures in cortical network models via multiple synergistic factors

Published: January 2025

Voltage-gated potassium conductances$g_K$play a critical role not only in normal neural function, but also in many neurological disorders and related therapeutic interventions. In particular, in an important animal model of epileptic seizures, 4-aminopyridine (4-AP) administration is thought to induce seizures by reducing$g_K$in cortex and other brain areas. Interestingly, 4-AP has also been useful in the treatment of neurological disorders such as multiple sclerosis (MS) and spinal cord injury, where it is thought to improve action potential propagation in axonal fibers. Here, we examined$g_K$downmodulation in bio-physical models of cortical networks that included different neuron types organized in layers, potassium diffusion in interstitial and larger extracellular spaces, and glial buffering. Our findings are fourfold. First,$g_K$downmodulation in pyramidal and fast-spiking inhibitory interneurons led to differential effects, making the latter much more likely to enter depolarization block. Second, both neuron types showed an increase in the duration and amplitude of action potentials, with more pronounced effects in pyramidal neurons. Third, a sufficiently strong$g_K$reduction dramatically increased network synchrony, resulting in seizure like dynamics. Fourth, we hypothesized that broader action potentials were likely to not only improve their propagation, as in 4-AP therapeutic uses, but also to increase synaptic coupling. Notably, graded synapses incorporating this effect further amplified network synchronization and seizure-like dynamics. Overall, our findings elucidate different effects that$g_K$downmodulation may have in cortical networks, explaining its potential role in both pathological neural dynamics and therapeutic applications.Significance StatementThe modulation of voltage-gated potassium-conductances$g_K$is thought to play an important role in epileptic seizures and therapeutic interventions in epilepsy, multiple sclerosis and spinal-cord injury. We show that$g_K$downmodulation can lead to a cascade of effects including changes in basal excitability, broadening of action potentials resulting in enhanced robustness to synaptic noise perturbations and strengthening of synaptic coupling; and differential effects in excitatory and fast-spiking inhibitory interneurons, promoting depolarization block in the latter under high downmodulation. All these effects synergistically contribute to the emergence of seizure-like dynamics in the form of almost-periodic synchronized neuronal-population spiking in cortical networks. Under appropriate levels,$g_K$downmodula tion can also have therapeutic effects by improving neuronal communication via the broadening of action potentials.

Решение задачи рассеяния света на атмосферных ледяных кристаллах крайне необходимо для интерпретации данных лазерного зондирования атмосферы. С целью ее решения рассчитаны матрицы обратного рассеяния света для ледяных атмосферных кристаллов произвольной формы с количеством граней 15, 20 и 40 в диапазоне размеров от 10 до 300 мкм в рамках приближения физической оптики. Расчеты проводились для случая хаотической пространственной ориентации частиц в рамках однократного рассеяния света на длинах волн излучения 0,532 и 1,064 мкм. Результаты статистического анализа демонстрируют незначительные отклонения в оптических характеристиках кристаллов произвольной формы с разным количеством граней. Показано, что оптические характеристики эталонной частицы, взятой из банка данных ИОА СО РАН, укладываются в вышеописанное распределение. Таким образом, работа подтверждает обоснованность использования рассчитанного банка данных для случая широкого набора частиц с количеством граней от 15 до 40. Полученные результаты необходимы для построения алгоритмов интерпретации лидарных данных зондирования перистых облаков.
Solving of the light scattering problem of atmospheric ice crystals is necessary for the interpretation of laser sensing data of atmosphere. This article presents the results of calculating light backscattering matrices for ice atmospheric crystals of arbitrary shape. The number of faces for these particles is 15, 20, and 40 and the size range is from 10 to 300 mm. Calculations were carried out within the physical optics approximation for the case of arbitrary spatial orientation of particles and single light scattering. The wavelengths of the incident light are 0.532 and 1.064 mm. According to the statistical analysis of crystals, their optical properties slightly differ. It is shown that the optical properties of an etalon particle taken from the IAO SB RAS data bank is satisfied the above distribution. Thus, the results confirm the validity of using the database for the case of a large set of particles with the number of faces from 15 to 40. The results are necessary for constructing algorithms for the interpretation of data of lidar sounding of cirrus clouds.
СОЦИАЛЬНО-ЭКОНОМИЧЕСКИЕ ДЕТЕРМИНАНТЫ КОНСОЛИДАЦИИ ГОРОДСКИХ СООБЩЕСТВ В ПРИГРАНИЧНЫХ РЕГИОНАХ ЦЕНТРАЛЬНО-ЧЕРНОЗЕМНОЙ РОССИИ

В статье рассматриваются социальные детерминанты консолидации городских сообществ. Цель статьи - верификация гипотез о взаимосвязи долгосрочных тенденций социально-экономического и социально-демографического развития городских сообществ в регионах российского приграничья и восприятия населением идеи социальной консолидации. На основе сопоставления данных статистики и результатов социологических исследований авторы доказывают, что отношение к консолидации не зависит от того, насколько благоприятными являются показатели демографического развития. На преобладание в общественном сознании интенции к консолидации оказывает неоднозначное воздействие фактор миграции (в случае значительной культурной дистанции она усиливается в среде коренных жителей, приобретая вид защитной реакции, короткая дистанция не побуждает к солидаризации). Выявлено, что более всего ориентированы на консолидацию «верхние» и «нижние» слои городского населения при относительной пассивности «средних», поэтому, как ни парадоксально, размывание «среднего класса» усиливает установки на солидаризацию. Способствуют их формированию и распространению информированность населения о наличии в городе элементов инфраструктуры консолидации (некоммерческие организации, общественные объединения и т.д.) и участие в их работе.
This article examines the social determinants of urban community consolidation. Its goal is to test hypotheses regarding the relationship between long-term socio-economic and socio-demographic trends in urban communities within Russia’s border regions and the population’s perception of social consolidation. By comparing statistical data and sociological research findings, the authors demonstrate that attitudes toward consolidation are not necessarily tied to favorable demographic indicators. Migration has a mixed impact on the prevalence of consolidation in the public consciousness (when cultural distance is significant, consolidation tendencies strengthen among natives as a protective response, whereas smaller cultural distances do not encourage solidarization). The study finds that the “upper" and “lower" strata of the urban population are most inclined toward consolidation, while the “middle" class remains relatively passive. Paradoxically, the erosion of the middle class fosters stronger consolidation attitudes. Additionally, the population’s awareness of the presence of consolidation infrastructure in their city (such as NGOs and public associations) and participation in these organizations contribute to the development and spread of consolidation efforts.
