Autores: Andreu Marfull Pujadas y Gabriel García Moreno. OBJETIVO: Exponer y contrastar la correlación entre la problemática de la vivienda en Ciudad Juárez y el contrato social mexicano, que desarrolla (o al menos tolera y mantiene) una notable desigualdad social con pobreza común y pobreza extrema. SINOPSIS: El planeta se urbaniza a un ritmo inédito. La población en las ciudades no cesa de crecer sin control, especialmente allí donde se establece del modo más informal. Todo cambia de escala y de sentido a marchas forzadas. En este contexto, el urbanismo incorpora en su narrativa la idea de que es posible ponerle remedio. La vivienda, para la sociedad más asolada por la pobreza, no es asequible. Se crean políticas en las que se desarrolla la solidaridad, la responsabilidad social y, claro, la vivienda mínima, pero no es suficiente. No se cubren todas las necesidades. Por esta razón, existe un espacio inferior al de la vivienda mínima, que aparece en la forma de autoconstrucción informal, para quienes no tienen derechos ni protección básicos ni un trabajo digno. La habitabilidad y el confort, sin límites económicos o tal vez con algunos razonables, conforman un espacio de trabajo eficaz sólo allí donde la sociedad es mínimamente justa y su economía lo soporta. Cuando el problema es la pobreza extrema, pocos remedios sirven. Existe una “ley del mercado” que dice que el suelo se subasta y se vende al “mejor postor”, donde quien se queda fuera experimenta la exclusión.

To improve reactivity and achieve a higher material efficiency, catalysts are often used in the form of clusters with nanometer dimensions, down to single atoms. Since the corresponding properties are highly structure-dependent, a suitable support is thus required to ensure cluster stability during operating conditions. Herein, an efficient method to stabilize cobalt nanoclusters on graphene grown on nickel substrates, exploiting the anchoring effect of nickel atoms incorporated in the carbon network is presented. The anchored nanoclusters are studied by in situ variable temperature scanning tunneling microscopy at different temperatures and upon gas exposure. Cluster stability upon annealing up to 200 °C and upon CO exposure at least up to 1 × 10−6 mbar CO partial pressure is demonstrated. Moreover, the dimensions of the cobalt nanoclusters remain surprisingly small (<3 nm diameter) with a narrow size distribution. Density functional theory calculations demonstrate that the interplay between the low diffusion barrier on graphene on nickel and the strong anchoring effect of the nickel atoms leads to the increased stability and size selectivity of these clusters. This anchoring technique is expected to be applicable also to other cases, with clear advantages for transition metals that are usually difficult to stabilize.

Electroencephalogram (EEG) signals immensely suffer from several physiological artifacts, including electrooculogram (EOG), electromyogram (EMG), and electrocardiogram (ECG) artifacts, which must be removed to ensure EEG’s usability. This paper proposes a novel one-dimensional convolutional neural network (1D-CNN), i.e., MultiResUNet3+, to denoise physiological artifacts from corrupted EEG. A publicly available dataset containing clean EEG, EOG, and EMG segments is used to generate semi-synthetic noisy EEG to train, validate and test the proposed MultiResUNet3+, along with four other 1D-CNN models (FPN, UNet, MCGUNet, LinkNet). Adopting a five-fold cross-validation technique, all five models’ performance is measured by estimating temporal and spectral percentage reduction in artifacts, temporal and spectral relative root mean squared error, and average power ratio of each of the five EEG bands to whole spectra. The proposed MultiResUNet3+ achieved the highest temporal and spectral p...

Background: The mechanisms and predictors of failed transradial approach in centers dedicated to this technique are not well characterized and were the main objective of this analysis. Methods: 6,808 consecutive patients undergoing transradial coronary procedures by operators with utilization rate greater than 90% were included. Simple and multiple logistic regression models were used to identify the predictors of failed transradial approach. Results: Transradial failure rate was 1.7%. Vascular complications were observed in 5%, with a prevalence of asymptomatic arterial occlusion and subcutaneous hematomas. Predictors of failure were female gender (OR = 1.87; 95% CI 1.29-2.71; p = 0.01), age &gt; 70 years (OR = 1.78; 95% CI 1.06-2.98; p = 0.03) and presence of chronic peripheral arterial disease (OR = 5.71; 95% CI 2.40-13.54; p &lt; 0.01). Conclusions: In a high-volume radial center, failure rate was &lt; 2% and variables associated with technical failure were female gender, advanc...

Background: Cancer-related cognitive impairment (CRCI) has been linked to functional brain changes and inflammatory processes. Hence, interventions targeting these underlying mechanisms are needed. In this study, we investigated the effects of a mindfulness-based intervention on brain function and inflammatory profiles in breast cancer survivors with CRCI. Methods: Female breast cancer survivors reporting cognitive complaints (n = 117) were randomly assigned to a mindfulness-based intervention (n = 43), physical training (n = 36), or waitlist control condition (n = 38). Region-of-interest (ROI) and graph theory analyses of resting state functional MRI data were performed to study longitudinal group differences in functional connectivity and organization in the default mode, dorsal attention, salience, and frontoparietal network. Additionally, bead-based immunoassays were used to investigate the differences in inflammatory profiles on serum samples. Measures were collected before, im...
