Distinguishable topology of the task-evoked functional genome networks in HIV-1 reservoirs
No full textHIV-1 reservoirs display a heterogeneous nature, lodging both intact and defective proviruses. To deepen our understanding of such heterogeneous HIV-1 reservoirs and their functional implications, we integrated basic concepts of graph theory to characterize the composition of HIV-1 reservoirs. Our analysis revealed noticeable topological properties in networks, featuring immunologic signatures enriched by genes harboring intact and defective proviruses, when comparing antiretroviral therapy (ART)-treated HIV-1-infected individuals and elite controllers. The key variable, the rich factor, played a pivotal role in classifying distinct topological properties in networks. The host gene expression strengthened the accuracy of classification between elite controllers and ART-treated patients. Markov chain modeling for the simulation of different graph networks demonstrated the presence of an intrinsic barrier between elite controllers and non-elite controllers. Overall, our work provides a prime example of leveraging genomic approaches alongside mathematical tools to unravel the complexities of HIV-1 reservoirs.</p
Tourists’ Mobility Experiences in European Capitals (2022)
No full textThe data for this study were collected in the summer of 2022 in ten European capitals: Amsterdam, Berlin, Brussels, London, Madrid, Paris, Prague, Rome, Stockholm, and Warsaw. The service safari method was used, which involved an immersive experience of urban transport by trained observers. Each participant conducted three separate journeys, using public transport (e.g., metro, tram, bus), motorized individual transport (e.g., taxis, rental cars), and active transport (e.g., walking, cycling, electric scooters). Each journey was thoroughly documented through reports, photographs, and GPS tracking. Observers, who were visiting the cities for the first time, recorded their experiences, paying particular attention to aspects such as the decision-making process for choosing a mode of transport, ease of navigation and ticket purchasing, travel time, comfort, safety, and environmental factors influencing mobility. The collected qualitative data were then organized, coded, and integrated with fuzzy set analysis, allowing for the identification of key factors affecting tourists' satisfaction with urban mobility. By applying this methodology, it was possible to capture both objective infrastructure and transport conditions as well as the subjective experiences of travelers.</p

Raw data for the article: Role of oxidative/nitrosative stress in dysfunction of rat’s intracerebral parenchymal arterioles in low sodium environment in the presence of vasopressin
No full textAll studies were performed on isolated rat’s intracerebral small vessels − parenchymal arterioles in low sodium environment in the presence of vasopressin, which mimics AVP-associated hyponatremia in vivo. The purpose of the present study was to investigate the mechanism of dysfunction, that is, constriction and impaired endothelial regulation of parenchymal arterioles in conditions of decreased Na+ concentration to 121 mM and increased AVP concentration to 15pg/ml. Raw data show percentage changes in parenchymal arteriole diameter (referred to Figures 2-7), which explain the mechanisms of vascular dysfunction in a low sodium and elevated vasopressin environment. Raw data for Figure 8 show detection of superoxide anion in isolated parenchymal vessels.The results of these studies demonstrated that the dysfunction of small vessels in these conditions is associated with 1) decreased involvement of NO in maintaining the basal tone of parenchymal arterioles, 2) involvement of oxidative/nitrosative stress, activation of V1a and ETA/ETB receptors. Metabolites of arachidonic acid, such as CYP450 4A-derived 20-HETE and COX-derived TXA2, were not involved in the studied mechanisms. Administration of NO precursor, L-arginine, likewise did not improve vascular disorders observed in low sodium environment in the presence of vasopressin. The present studies revealed also increased superoxide formation in such conditions.</p

Effective light-induced Hamiltonian for atoms with large nuclear spin
No full textUltracold fermionic atoms, having two valence electrons, exhibit a distinctive internal state structure, wherein the nuclear spin becomes decoupled from the electronic degrees of freedom in the ground electronic state. Consequently, the nuclear spin states are well isolated from the environment, rendering these atomic systems an opportune platform for quantum computation and quantum simulations. Coupling with off-resonance light is an essential tool to selectively and coherently manipulate the nuclear spin states. In this paper, we present a systematic derivation of the effective Hamiltonian for the nuclear spin states of ultracold fermionic atoms due to such an off-resonance light. We obtain compact expressions for the scalar, vector, and tensor light shifts taking into account both linear and quadratic contributions to the hyperfine splitting. The analysis has been carried out using the Green operator approach and solving the corresponding Dyson equation. Finally, we analyze different scenarios of light configurations which lead to the vector- and tensor-light shifts, as well as the pure spin-orbit coupling for the nuclear spin.The .zip file contains all relevant Figures in the pdf and png formats as well as related formulas and details of analytical derivation of the effective Hamiltonian.</p
