Project description:Neurons responding to different whiskers are spatially intermixed in the superficial layer 2/3 (L2/3) of the rodent barrel cortex, where a single whisker deflection activates a sparse, distributed neuronal population that spans multiple cortical columns. How the superficial layer of the rodent barrel cortex is organized to support such distributed sensory representations is not clear. In a computer model, we tested the hypothesis that sensory representations in L2/3 of the rodent barrel cortex are formed by activity propagation horizontally within L2/3 from a site of initial activation. The model explained the observed properties of L2/3 neurons, including the low average response probability in the majority of responding L2/3 neurons, and the existence of a small subset of reliably responding L2/3 neurons. Sparsely propagating traveling waves similar to those observed in L2/3 of the rodent barrel cortex occurred in the model only when a subnetwork of strongly connected neurons was immersed in a much larger network of weakly connected neurons.

Project description:The design principles of institutions that visibly and significantly affect citizens' lives are likely to be politically salient. Popular support for these principles is in turn crucial for institutional viability and effectiveness. Transboundary pandemics are a case in point. Understanding citizens' preferences regarding the design of international alliances set up to mass-produce and distribute vaccines is likely to determine citizens' subsequent cooperation with vaccination campaigns. This study explores Germans' preferences for international COVID-19 vaccine alliance design principles. We conducted a conjoint experiment at a recurring cognitive moment in many pandemics' cycles, between the initial outbreak and a more devastating but still-unknown second wave, when infection rates were very low, yet no policy solutions had been developed. We analyzed preferences regarding four building blocks: (1) alliance composition (size; EU-centrism), (2) alliance distribution rules (joining cost; vaccine allocation), (3) vaccine nationalism (cost per German household; coverage in Germany) and (4) vaccine producer confidence (origin; type). Distribution rules, political ideology and personal perceptions of pandemic threat matter little. But a larger alliance size and dominant EU-country composition increase alliance support. And vaccine nationalism is key: support increases with both lower costs and larger coverage for own-nation citizens. Moreover, support goes down for Chinese and American producers and increases for Swiss and especially own-nation producers. In sum, a realist and technocratic outlook is warranted at the cognitive stage in pandemic cycles when no solutions have been found, yet the worst already seems to be over, as national self-interest reigns supreme in popular attitudes.Supplementary informationThe online version contains supplementary material available at 10.1007/s11077-021-09435-1.

Project description:The visual cortex represents stimuli through the activity of neuronal populations. We measured the evolution of this activity in space and time by imaging voltage-sensitive dyes in cat area V1. Contrast-reversing stimuli elicit responses that oscillate at twice the stimulus frequency, indicating that signals originate mostly in complex cells. These responses stand clear of the noise, whose amplitude decreases as 1/frequency, and yield high-resolution maps of orientation preference and retinotopy. We first show how these maps are combined to yield the responses to focal, oriented stimuli. We then study the evolution of the oscillating activity in space and time. In the orientation domain, it is a standing wave. In the spatial domain, it is a traveling wave propagating at 0.2-0.5 m/s. These different dynamics indicate a fundamental distinction in the circuits underlying selectivity for position and orientation, two key stimulus attributes.

Project description:During the COVID-19 pandemic, many residents of high-income countries (HICs) were eligible for COVID-19 vaccine boosters, while many residents of lower-income countries (LICs) had not yet received a first dose. HICs made some efforts to contribute to COVID-19 vaccination efforts in LICs, but these efforts were limited in scale. A new literature discusses the normative importance of an international redistribution of vaccines. Our analysis contributes an empirical perspective on the willingness of citizens in a HIC to contribute to such efforts (which we term international vaccine solidarity). We analyse the levels and predictors of international vaccine solidarity. We surveyed a representative sample of German adults (n = 2019) who participated in a two-wave YouGov online survey (w1: Sep 13-21, 2021 and w2: Oct 4-13, 2021). International vaccine solidarity is measured by asking respondents preferences for sharing vaccine supplies internationally versus using that supply as boosters for the domestic population. We examine a set of pre-registered hypotheses. Almost half of the respondents in our sample (48%) prioritize giving doses to citizens in less developed countries. A third of respondents (33%) prefer to use available doses as boosters domestically, and a fifth of respondents (19%) did not report a preference. In line with our hypotheses, respondents higher in cosmopolitanism and empathy, and those who support domestic redistribution exhibit more support for international dose-sharing. Older respondents (who might be more at risk) do not consistently show less support for vaccine solidarity. These results help us to get a better understanding of the way citizens' form preferences about a mechanism that redistributes medical supplies internationally during a global crisis.

Project description:Discovery of novel splicing from RNA sequence data remains a critical and exciting focus of transcriptomics, but reduced alignment power impedes expression quantification of novel splice junctions.Here, we profile performance characteristics of two-pass alignment, which separates splice junction discovery from quantification. Per sample, across a variety of transcriptome sequencing datasets, two-pass alignment improved quantification of at least 94% of simulated novel splice junctions, and provided as much as 1.7-fold deeper median read depth over those splice junctions. We further demonstrate that two-pass alignment works by increasing alignment of reads to splice junctions by short lengths, and that potential alignment errors are readily identifiable by simple classification. Taken together, two-pass alignment promises to advance quantification and discovery of novel splicing events.arul@med.umich.edu, nesvi@med.umich.eduTwo-pass alignment was implemented here as sequential alignment, genome indexing, and re-alignment steps with STAR. Full parameters are provided in Supplementary Table 2.Supplementary data are available at Bioinformatics online.

Project description:Speckle tracking based on block matching is the most common method for multi-dimensional motion estimation in ultrasound elasticity imaging. Extension of two-dimensional (2-D) methods to three dimensions (3-D) has been problematic because of the large computational load of 3-D tracking, as well as performance issues related to the low frame (volume) rates of 3-D images. To address both of these problems, we have developed an efficient two-pass tracking method suited to cardiac elasticity imaging. PatchMatch, originally developed for image editing, has been adapted for ultrasound to provide first-pass displacement estimates. Second-pass estimation uses conventional block matching within a much smaller search region. 3-D displacements are then obtained using correlation filtering previously shown to be effective against speckle decorrelation. Both simulated and in vivo canine cardiac results demonstrate that the proposed two-pass method reduces computational cost compared to conventional 3-D exhaustive search by a factor of 10. Moreover, it outperforms one-pass tracking by a factor of about 3 in terms of root-mean-square error relative to available ground-truth displacements.

Project description:Scholars, policy makers, and the general public have expressed growing concern about the possibility of large-scale political violence in the United States. Prior research substantiates these worries, as studies reveal that many American partisans support the use of violence against rival partisans. Here, we propose that support for partisan violence is based in part on greatly exaggerated perceptions of rival partisans’ support for violence. We also predict that correcting these inaccurate “metaperceptions” can reduce partisans’ own support for partisan violence. We test these hypotheses in a series of preregistered, nationally representative, correlational, longitudinal, and experimental studies (total n = 4,741) collected both before and after the 2020 US presidential election and the 2021 US Capitol attack. In Studies 1 and 2, we found that both Democrats’ and Republicans’ perceptions of their rival partisans’ support for violence and willingness to engage in violence were very inaccurate, with estimates ranging from 245 to 442% higher than actual levels. Further, we found that a brief, informational correction of these misperceptions reduced support for violence by 34% (Study 3) and willingness to engage in violence by 44% (Study 4). In the latter study, a follow-up survey revealed that the correction continued to significantly reduce support for violence approximately 1 mo later. Together, these results suggest that support for partisan violence in the United States stems in part from systematic overestimations of rival partisans’ support for violence and that correcting these misperceptions can durably reduce support for partisan violence in the mass public.

Project description:ObjectiveTo determine whether international experience is associated with greater comfort in providing care to US children who are immigrants, refugees, and traveling internationally.Study designFollowing enrollment into the 2018 American Board of Pediatrics Maintenance of Certification program, general pediatricians and subspecialists received a voluntary, online survey with questions about their experience and self-reported comfort caring for immigrant, refugee, and internationally traveling children and previous international experiences. Using multivariable logistic regression, we examined how previous international experiences, and other personal characteristics, were associated with self-reported comfort.ResultsA total of 5461 eligible participants completed the survey; 76.3%, (n = 4168) reported caring for immigrant children, 35.8% (n = 1957) cared for refugee children, and 79.8% (n = 4358) cared for children traveling internationally. High levels of comfort caring for immigrant children were reported by 68.5% (n = 3739), for refugee children by 50.1% (n = 2738), and for children traveling internationally by 72.7% (n = 3968). One-third of respondents (34.1%, n = 1866) reported past international experiences. In multivariable analysis, respondents with previous international experience and of Hispanic origin were significantly more likely to report high levels of comfort caring for all 3 populations.ConclusionsThe majority of pediatricians report caring for children in the US who are immigrants, refugees, and traveling internationally, and previous international experience was associated with greater comfort with care. Training programs and professional organizations should consider ways to encourage a more diverse workforce and to support all pediatricians in achieving the skills and confidence required to care for children in our highly mobilized society.

Project description:Photo-ID is widely used in security settings, despite research showing that viewers find it very difficult to match unfamiliar faces. Here we test participants with specialist experience and training in the task: passport-issuing officers. First, we ask officers to compare photos to live ID-card bearers, and observe high error rates, including 14% false acceptance of 'fraudulent' photos. Second, we compare passport officers with a set of student participants, and find equally poor levels of accuracy in both groups. Finally, we observe that passport officers show no performance advantage over the general population on a standardised face-matching task. Across all tasks, we observe very large individual differences: while average performance of passport staff was poor, some officers performed very accurately--though this was not related to length of experience or training. We propose that improvements in security could be made by emphasising personnel selection.
