Economía social comunitaria con identidad desde la perspectiva intercultural de género
The study was carried out in ten communities located in the rural area of Siuna, Autonomous Region of the Northern Caribbean Coast, Nicaragua. Its objectives are to characterize the population, community economic and social development with identity from an intercultural gender perspective, to describe the state of art of these from the participation of the people, and to analyze realities, contexts, and scenarios for thepromotion of local community economies for the life of the people. The study was developed under the quantitative approach with a descriptive level, data were collected with a structured survey with closed questions on a Likert scale and sectoral workshops. For data processing, statistical techniques were applied to organize, tabulate, represent and synthesize data related to the study variables. The results show that men are responsible for the leadership of the household. A quarter of the population is young and economically active. In these communities, agriculture is the main livelihood and the average salary is 3,800 córdobas, surviving daily on 157.5 córdobas. It was learned that more than half of the population of school age is active in the different modalities. There are sixteen schools, and the modality with the most students is multi-grade primary school. It is vital to implement trade schools to generate employment and self-employment opportunities.

Recovering Sustainable Mobility after COVID-19: The Case of Almeria (Spain)
The COVID-19 pandemic brought about a significant change in mobility habits within cities, leading to a significant decrease in the use of collective urban transport in many countries that has been only partially and unevenly reversed. In this context, many cities are analyzing what factors are hindering this recovery process to design actions to promote sustainable mobility. Thus, this study, carried out in the city of Almeria (Spain), tried to analyze whether the main operating variables of the municipal bus network (frequency, average vehicle occupancy, the length of the lines, urban or suburban character, circularity, nodality, and intermodality) have an impact on the annual number of users recovered in 2022 compared to 2019. Although a strong statistical correlation between variables was not observed, the overall results show that the lines that have recovered the most users on average are suburban lines, as well as the nodal lines that serve key centroids such as the university, highlighting that the dependence of users on public transport might be the
most important determinant in the recovery process, more than other variables representative of the service’s intrinsic quality such as frequency or average vehicle occupancy. This result shows the importance of facilitating public transport to those who lack alternatives, as well as the convenience of restrictions on less sustainable transportation alternatives for the prompt recovery of the space lost by urban public transportation
Advances in the Integration of Sustainable Drainage Systems into Urban Planning: A Case Study
Climate change is arguably the greatest challenge facing cities today. Its severe consequences have created the need for sustainable urban planning. In this regard, Sustainable Drainage Systems (SuDS) have contributed in recent years to alleviating environmental problems caused by soil sealing and enhancing the resilience of cities to climate change. However, in most cases, the level of implementation is limited to solving environmental problems caused by inadequate urban planning. To change this, in recent years some countries have proposed recommendations to integrate these systems into their urban planning regulations, but these have been general and have not defined specific measures. This paper proposes to achieve this goal by using case studies of three countries
with similar characteristics (Spain, Italy and France). A common framework for the integration of SuDS in planning has been proposed that can be exported to other similar places. The urban scales of intervention have been defined (city, neighborhood and street), as well as the actions to be carried out (analysis, planning and regulatory measures) and the urban plans to which they should be applied.
This proposal represents an advancement in the application of SuDS as a primary control measure. This breakthrough will significantly improve the resilience of the cities of the future, making them more resilient to the effects of weather and climate change
Perturbation-Based Modeling Unveils the Autophagic Modulation of Chemosensitivity and Immunogenicity in Breast Cancer Cells
In the absence of new therapeutic strategies, chemotherapeutic drugs are the most widely
used strategy against metastatic breast cancer, in spite of eliciting multiple adverse effects and having
low responses with an average 5-year patient survival rate. Among the new therapeutic targets
that are currently in clinical trials, here, we addressed the association between the regulation of the
metabolic process of autophagy and the exposure of damage-associated molecular patterns associated
(DAMPs) to immunogenic cell death (ICD), which has not been previously studied. After validating
an mCHR-GFP tandem LC3 sensor capacity to report dynamic changes of the autophagic metabolic
flux in response to external stimuli and demonstrating that both basal autophagy levels and response
to diverse autophagy regulators fluctuate among different cell lines, we explored the interaction
between autophagy modulators and chemotherapeutic agents in regards of cytotoxicity and ICD
using three different breast cancer cell lines. Since these interactions are very complex and variable
throughout different cell lines, we designed a perturbation-based model in which we propose specific
modes of action of chemotherapeutic agents on the autophagic flux and the corresponding strategies
of modulation to enhance the response to chemotherapy. Our results point towards a promising
therapeutic potential of the metabolic regulation of autophagy to overcome chemotherapy resistance
by eliciting ICD.Universidad de Costa Rica/[803-B6-600]/UCR/Costa RicaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Centro de Investigación en Enfermedades Tropicales (CIET)UCR::Vicerrectoría de Docencia::Salud::Facultad de Microbiologí

Applications of non-intrusive methods to study the sand cat: a field study in the Sahara Desert
Surveys based on indirect signs and camera trapping are two non-invasive methods extensively used for monitoring elusive mammals. Both approaches can be useful to obtain key information on wildlife in remote areas, since they may allow for the logistically viable design of optimal field frameworks. The sand cat (Felis margarita) is a feline that inhabits the Sahara Desert, the Arabian Peninsula, and western Asian deserts. Its basic ecology is poorly known and the status and impacts of threats are difficult to assess. Some local population declines have been detected, and more research is needed. Based on field surveys carried out in the Atlantic Sahara, we have evaluated the applications of both methods to study this species. Our results show that (a) camera trapping provided reliable data on several key aspects of its ecology, (b) walking surveys to collect feces for molecular data failed completely, and (c) for footprints, identification problems and the marked effects of the absence of optimal substrates and the prevalence of wind are relevant handicaps. Beyond this evaluation, we provide for the first time some key aspects of the ecology of sand cats in the Sahara Desert, including habitat selection, density, diel activity, and predator–prey relationships.Funding for open access publishing: Universidad de Granada/CBUA.

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level
