    Abstract This paper analyzes the impact of collisions in a system of N identical hard-core particles driven according to a velocity jump process. The physical space is essentially a channel in R with a probability of occupants being able to pass each other. The system mimics what nature does, where individuals pass one another in a narrow channel while making incidental contact with those moving in the opposite direction. The passing probability may depend on the particles' size and the channel's width. Starting from the particle level model, we systematically derive a nonlinear transport equation based on an asymptotic expansion. Under low-occupied fractions, numerical solutions of both the kinetic model and the stochastic particle system are compared well during biased and unbiased random velocity changes. Analysis of the subpopulation motility within a large population exhibits the consequences of volume exclusions and channel confinements on the traveling speeds.

  2. Article ; Online: Clustering Financial Return Distributions Using the Fisher Information Metric.

    Abstract Information geometry provides a correspondence between differential geometry and statistics through the Fisher information matrix. In particular, given two models from the same parametric family of distributions, one can define the distance between these models as the length of the geodesic connecting them in a Riemannian manifold whose metric is given by the model's Fisher information matrix. One limitation that has hindered the adoption of this similarity measure in practical applications is that the Fisher distance is typically difficult to compute in a robust manner. We review such complications and provide a general form for the distance function for one parameter model. We next focus on higher dimensional extreme value models including the generalized Pareto and generalized extreme value distributions that will be used in financial risk applications. Specifically, we first develop a technique to identify the nearest neighbors of a target security in the sense that their best fit model distributions have minimal Fisher distance to the target. Second, we develop a hierarchical clustering technique that utilizes the Fisher distance. Specifically, we compare generalized extreme value distributions fit to block maxima of a set of equity loss distributions and group together securities whose worst single day yearly loss distributions exhibit similarities.

    Abstract Background: Predominance of blind feeding tube placement makes esophageal tube misplacement and aspiration risk commonplace. Accurate estimation of nose-to-stomach length could reduce this risk. Standards for estimating this length were audited against the length measured from guided tube placement.
    Methods: This prospective, single-center observational study used electromagnet-guided tube placement to measure the length from nose to gastric body flexure as part of routine care. This measurement was used to audit standard equations used to estimate this length from external measures: xiphisternum-ear-nose + 10 cm (XEN+10), nose-ear-xiphisternum (NEX), and Hanson_A and Hanson_B.
    Results: From April 23, 2015, to March 2, 2020, measurements were obtained from 200 primary tube placements. Median length to the gastric body flexure (61 cm) was significantly different from that to the pre-gastroesophageal junction flexure (48 cm) or lengths predicted by NEX (51 cm) or Hanson_A (50.5 cm) and Hanson_B (56.1 cm) (all P < .00001) but similar to XEN+10 (61 cm). Esophageal placement was a potential risk for all methods (NEX: 96.3%, Hanson_A: 99.5%, Hanson_B: 86.9%, XEN+10: 43.2%) and a definite risk for most (NEX and Hanson_A: 14.9%, Hanson_B: 1%, XEN+10: 0%).
    Conclusions: NEX and Hanson methods of predicting the length from nose to gastric body flexure are too short and risk esophageal misplacement. XEN+10 reduces but does not eliminate this risk. External measurement predictions are clinically unsafe as a guide blind tube placement. Guided placement is recommended.

    Abstract As the world comes closer to the eradication of polio, the question of preparing for life after this debilitating disease becomes increasingly pertinent. This paper focuses on on-going institutional attempts to conceptualise, plan, and deliver a world after polio. Drawing upon interviews with global health officials and ethnographic fieldwork with eradication initiatives in Nigeria and Pakistan, I explore how international donors are transitioning towards life after the disease and the curtailment of the substantial resources it has successfully mobilised. Focusing specifically on the wind-down of the Global Polio Eradication Initiative, I critically examine key risks emerging from polio transition and highlight a series of spatial and political assumptions about the emergent post-polio contours of global health that have largely been obscured by attempts to render transition planning as little more than a technical exercise.

    Abstract COVID-19 forced humanity to think about new ways of working globally without physically being present with other people, and eXtended Reality (XR) systems (defined as Virtual Reality, Augmented Reality and Mixed Reality) offer a potentially elegant solution. Previously seen as mainly for gaming, commercial and research institutions are investigating XR solutions to solve real world problems from training, simulation, mental health, data analysis, and studying disease progression. More recently large corporations such as Microsoft and Meta have announced they are developing the Metaverse as a new paradigm to interact with the digital world. This article will look at how visualization can leverage the Metaverse in bioinformatics research, the pros and cons of this technology, and what the future may hold.

    Abstract Binary systems of supermassive black holes are promising sources of low-frequency gravitational waves (GWs) and bright electromagnetic emission. Pulsar timing array GW searches for individual binaries have been limited to only a few candidate systems due to computational demands, which get worse as more pulsars are added. By modeling the GW signal using only components from when the GW passes Earth (rather than also each pulsar), we find constraints on the binary's total mass and GW frequency that are similar to a full signal analysis, yet ∼70 times more efficient.
