Replication Data for: Data-driven signal-to-noise enhancement in scattering near-field infrared microscopy
No full textThis study introduces a machine-learning approach to enhance signal-to-noise ratios in scattering-type scanning near-field optical microscopy (s-SNOM). While s-SNOM offers high spatial resolution, its effectiveness is often hindered by low signal levels, particularly in weakly absorbing samples. To address these challenges, we utilize a data-driven "patch-based" machine learning reconstruction method, incorporating modern generative adversarial neural networks (CycleGANs) for denoising s-SNOM images. This method allows for flexible reconstruction of images of arbitrary sizes, a critical capability given the variable nature of scanned sample areas in point-scanning probe-based microscopies. The CycleGAN model is trained on unpaired sets of images captured at both rapid and extended acquisition times, thereby modeling instrument noise while preserving essential topographical and molecular information. Results show significant improvements in image quality, as indicated by higher structural similarity index (SSIM) and peak signal-to-noise ratio (PSNR) values, comparable to those obtained from images captured with four times the integration time. This method not only enhances image quality but also has the potential to reduce overall data acquisition time, making high-resolution s-SNOM imaging more feasible for a wide range of biological and materials science applications
Diversity, Equity, and Inclusion in Disaster Management: A Review of Initiatives, Challenges, and Opportunities
No full textIn an era marked by a rapid increase in the number, frequency, and severity of climate hazards, the significance of diversity, equity, and inclusion (DEI) in disaster management (DM) and policymaking cannot be overstated. Demographic shifts coupled with asymmetric population growth have created new challenges for local jurisdictions, that are already under-resourced, to properly identify and respond to community needs and expectations particularly when disasters strike. Research underscores the urgency of addressing DEI in DM, as marginalized and underserved communities often bear the brunt of disaster impacts due to systemic inequalities in access to resources, infrastructure, and decision-making processes. This paper will discuss the background of DEI and its introduction to the DM domain. It will also review the importance of DEI, current initiatives in place to further DEI in DM, the challenges that need to be addressed as DEI is introduced or reintroduced to different phases of DM, and opportunities where DEI will strengthen DM. This work is informed by and strives to provide examples from the national-level DEI landscape as well as global initiatives and efforts such as those by the United Nations Office for Disaster Risk Reduction (UNDRR)
Ordenanza General para la defensa de Caracas contra la peste, 1909 junio 5
No full textLa ordenanza general destaca la importancia de erradicar la plaga enfocándose en la destrucción de ratas y ratones en Caracas. Establece medidas detalladas para la organización sanitaria de la ciudad, la protección de las habitaciones, la destrucción directa de las ratas, el saneamiento y aislamiento de los focos de roedores, y medidas generales que se refieren especialmente a ciertos edificios públicos, grandes cloacas y albañales. Entre las medidas específicas se encuentran la designación de un "Oficial de Sanidad" en cada parroquia, la obligación de los propietarios de casas de permitir la entrada de inspectores sanitarios, la instalación de depósitos metálicos para desperdicios alimenticios, la prohibición de botar residuos alimenticios al suelo, entre otras. También se establece la necesidad de proteger árboles frutales contra las ratas, así como la destrucción de madrigueras de ratas y la limpieza constante de las quebradas que atraviesan la ciudad. —— The general ordinance highlights the importance of eradicating the plague by focusing on the destruction of rats and mice in Caracas. It establishes detailed measures for the city's sanitary organization, habitat protection, rat destruction, sanitation and isolation of rodent foci, and general measures that specifically refer to certain public buildings, large sewers, and drains. Among the specific measures are the appointment of a "Health Officer" in each parish, the obligation of homeowners to allow the entry of health inspectors, the installation of metal containers for food waste, the prohibition of disposing of food waste on the ground, among others. It also establishes the need to protect fruit trees from rats, as well as the destruction of rat burrows and the constant cleaning of the streams that run through the city. 32 f. (16 p.
Replication Data for: Transcriptional Regulation of Living Materials via Extracellular Electron Transfer
No full textIndividual cells remodel natural biomaterials, such as the extracellular matrix, through signal transduction and gene expression to influence network properties including stiffness, pattern formation, cell morphology, and molecular transport. In contrast, non-living synthetic polymer networks struggle to recreate this behavior due to their lack of autonomous actuators (i.e., cells), restricted computational inputs (e.g., light, pH, enzymes), and the limited orthogonality between network chemistries. Towards combining the advantages of living and synthetic systems, engineered living materials leverage genetic and metabolic programming of cells to establish control over material-wide properties. Here, we demonstrate that extracellular electron transfer (EET), a microbial respiration process, can serve as a tunable bridge between live cell metabolism and synthetic material properties. In our system, EET flux from Shewanella oneidensis to a copper catalyst controls atom-transfer radical polymerization, which cross-links methacrylate-functionalized macromers to form a polymer network (hydrogel). We first demonstrate that design rules from fluorescence parameterization in synthetic biology can be applied to predictably control polymer network mechanics using genetic circuits that regulate EET flux. Next, capitalizing on the modularity of genetic circuitry, we program transcriptional Boolean logic gates to regulate EET gene expression and design computational polymer networks that mechanically respond to combinations of molecular inputs. We then leverage the modularity and substrate scope of EET to direct another synthetic cross-linking reaction, copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC), which can also be controlled using transcriptional logic. Finally, we utilize our EET-based material interface to logically control fibroblast morphology. Our results demonstrate the utility of EET as a bridge for controlling abiotic materials and how the rational design of genetic circuits can be leveraged to emulate physiological behavior in polymer networks
