Public Health-Led Insights on Electric Micro-mobility Adoption and Use : a Scoping Review
Altres ajuts: acords transformatius de la UABUnidad de excelencia María de Maeztu CEX2019-000940-MThe advent of electric micro-mobility (EMM) has transformed the urban mobility landscape, with projections indicating a 5-10% increase in its modal share in European cities by 2030. In this scoping review, we aimed to comprehensively examine the key determinants of EMM adoption and usage from a public health perspective. Sixty-seven articles were included in the analysis, primarily covering e-bikes and e-scooters. The determinants were categorised into two broad categories: (1) contextual determinants that encompass enabling and hindering factors related to legal frameworks, transportation systems and infrastructure, and technology, and (2) individual-level determinants that pertain to intrinsic motivations and deterrents of individuals. Our findings reveal that EMM vehicles are widely perceived as a cost-effective, flexible, ad hoc, and fast mode of transportation within urban areas, augmenting accessibility and connectivity. Additionally, the lightweight, foldable, and transportable nature of these vehiclesis highly appreciated by users. However, several barriers have also been identified, including inadequate infrastructure and end-of-trip facilities, limited capability to traverse diverse terrains and trip scenarios, acquisition and maintenance costs, limited carrying capacities, technical failures, and accident risks. Our results suggest that the interplay of contextual enablers and barriers and personal motivations and deterrents drive the emergence, adoption, and usage of EMM. Hence, a comprehensive understanding of both contextual and individual-level determinants is crucial for ensuring a sustainable and healthy uptake of EMM

The vital contribution of microorganisms to marine ROS levels, particularly superoxide, has only recently come to light, and thus the specific biological sources and pathways involved in ROS production are largely unknown. To better understand the biogenic controls on ROS levels in tropical oligotrophic systems, we determined rates of superoxide production under various conditions by natural populations of the nitrogen-fixing diazotroph Trichodesmium obtained from various surface waters in the Sargasso Sea. Trichodesmium colonies collected from eight different stations all produced extracellular superoxide at high rates in both the dark and light. Colony density and light had a variable impact on extracellular superoxide production depending on the morphology of the Trichodesmium colonies. Raft morphotypes showed a rapid increase in superoxide production in response to even low levels of light, which was not observed for puff colonies. In contrast, superoxide production rates per colony decreased with increasing colony density for puff morphotypes but not for rafts. These findings point to Trichodesmium as a likely key source of ROS to the surface oligotrophic ocean. The physiological and/or ecological factors underpinning morphology-dependent controls on superoxide production need to be unveiled to better understand and predict superoxide production by Trichodesmium and ROS dynamics within marine systems.Major support for this work was provided by NSF OCE-

Data Commons
Publicly available data from open sources (e.g., United States Census Bureau
(Census), World Health Organization (WHO), Intergovernmental Panel on Climate
Change (IPCC)) are vital resources for policy makers, students and researchers
across different disciplines. Combining data from different sources requires
the user to reconcile the differences in schemas, formats, assumptions, and
more. This data wrangling is time consuming, tedious and needs to be repeated
by every user of the data. Our goal with Data Commons (DC) is to help make
public data accessible and useful to those who want to understand this data and
use it to solve societal challenges and opportunities. We do the data
processing and make the processed data widely available via standard schemas
and Cloud APIs. Data Commons is a distributed network of sites that publish
data in a common schema and interoperate using the Data Commons APIs. Data from
different Data Commons can be joined easily. The aggregate of these Data
Commons can be viewed as a single Knowledge Graph. This Knowledge Graph can
then be searched over using Natural Language questions utilizing advances in
Large Language Models. This paper describes the architecture of Data Commons,
some of the major deployments and highlights directions for future work
Novel genetic mutations in genes AGBL5 and TULP1 for presumed unilateral retinitis pigmentosa managed with low vision rehabilitation: A case report and review
Background: Retinitis pigmentosa is a group of hereditary retinal diseases characterized by the degeneration of rod and cone photoreceptors. It commonly results in night blindness followed by tunnel vision and central vision reduction. The classic triad of clinical signs includes pigmented bone spicules, waxy disc pallor, and arterial attenuation. Unilateral retinitis pigmentosa is rare and can be supported with ancillary testing including genetic and laboratory studies to rule out differential diagnoses.
Case Report: A 68-year-old Hispanic female was referred to the low vision rehabilitation clinic due to progressive vision loss in the left eye (OS) that began 15 years ago. The vision was normal in the right eye (OD). Additionally, she suffered from hearing loss in the right ear since age 3. Examination revealed abnormal visual acuity, visual field, fundus appearance, optical coherence tomography, and electrodiagnostic test results in the OS only. Laboratory studies ruled out various infectious, autoimmune, traumatic, and toxic drug etiologies. Genetic testing revealed novel mutations in genes associated with retinitis pigmentosa.
Conclusion: The genetic testing results along with the clinical examination and electrodiagnostic evaluation supports the diagnosis of unilateral retinitis pigmentosa
The influence of emotional distraction on verbal working memory: An fMRI investigation comparing individuals with schizophrenia and healthy adults
The ability to maintain information over short periods of time (i.e., working memory) is critically important in a variety of cognitive functions including language, planning, and decision-making. Recent functional Magnetic Resonance Imaging (fMRI) research with healthy adults has shown that brain activations evoked during the delay interval of working memory tasks can be reduced by the presentation of distracting emotional events, suggesting that emotional events may take working-memory processes momentarily offline. Both executive function and emotional processing are disrupted in schizophrenia, and here we sought to elucidate the effect of emotional distraction upon brain activity in schizophrenic and healthy adults performing a verbal working memory task. During the delay period between the memoranda and memory probe items, emotional and neutral distractors differentially influenced brain activity in these groups. In healthy adults, the hemodynamic response from posterior cingulate, orbital frontal cortex, and the parietal lobe strongly differentiated emotional from neutral distractors. In striking contrast, schizophrenic adults showed no significant differences in brain activation when processing emotional and neutral distractors. Moreover, the influence of emotional distractors extended into the memory probe period in healthy, but not schizophrenic, adults. The results suggest that although emotional items are highly salient for healthy adults, emotional items are no more distracting than neutral ones to individuals with schizophrenia
Nova-like Cataclysmic Variables in the Infrared
Novalike cataclysmic variables have persistently high mass transfer rates and prominent steady state accretion disks. We present an analysis of infrared observations of twelve novalikes obtained from the Two Micron All Sky Survey, the Spitzer Space Telescope, and the Wide-field Infrared Survey Explorer All Sky Survey. The presence of an infrared excess at >3-5 microns over the expectation of a theoretical steady state accretion disk is ubiquitous in our sample. The strength of the infrared excess is not correlated with orbital period, but shows a statistically significant correlation (but shallow trend) with system inclination that might be partially (but not completely) linked to the increasing view of the cooler outer accretion disk and disk rim at higher inclinations. We discuss the possible origin of the infrared excess in terms of emission from bremsstrahlung or circumbinary dust, with either mechanism facilitated by the mass outflows (e.g., disk wind/corona, accretion stream overflow, and so on) present in novalikes. Our comparison of the relative advantages and disadvantages of either mechanism for explaining the observations suggests that the situation is rather ambiguous, largely circumstantial, and in need of stricter observational constraints.Peer reviewe
