title: Risk_dash, A Python Framework to Model Portfolio Risk
Creators: name: van Oene, Alexander
Publisher: name: Utah State University
Year: 2021

description: While there are many Python packages that provide ways to do data analysis, in fact the package utilizes pandas, numpy, and scipy heavily, there are few that apply and handle common tasks that analysts face in quantifying market risk. pyfolio is one of those packages, however it forces you to utilize their infrastructure package Zipline where as risk_dash aims to provide a framework to formalize the data flow while being totally customizable for the analyst. risk_dash is comprised of classes and methods to handle the data flow and calculation of market risk metrics at the asset and portfolio level. In use, this package should ease the developer’s work in building a comprehensive risk analytics application and specifying the underlying risk distribution. This package does not aim to generate trade ideas, but quantify the market risks portfolios of securities face. Included is an example of an application that utilizes this framework focusing on an equity portfolio.

description: We have investigated the tunable lateral shift and polarization beam splitting of the transmitted light beam through electro-optic crystals, based on the Pockels effect. The positive and negative lateral shifts could be easily controlled by adjusting the permittivity tensor, which is modulated by the external applied electric field. An alternative way to realize the polarization beam splitter was also proposed by the polarization-dependent lateral shifts. Numerical simulations for Gaussian-shaped incident beam have demonstrated the above theoretical results obtained by stationary phase method. All these phenomena have potential applications in optical devices.

description: The scattering of Rb atoms on an anti-relaxation coating was studied. No significant change in the spin relaxation probability of Rb atoms by single scattering from a tetracontane surface was observed by cooling the film from 305 to 123 K. The mean surface dwell time was estimated using a time-resolved method.Delay-time spectra, from which mean surface dwell times can be estimated, were measured at 305, 153, and 123 K, with a time window of $9.3\times 10^{-5}$ s. The increase in mean surface dwell time with cooling from 305 to 123 K was smaller than $4.4\times 10^{-6}$ s, which is significantly smaller than the value expected from the mean dwell time at room temperature measured using the Larmor frequency shift. These results can be explained by assuming a small number of scattering components, with a mean surface dwell time at least three orders of magnitude longer than the majority component.
title: The Effects of Bank Lobbying and Elections Surprises
Creators: name: Tarbet, Gregory Logan
Publisher: name: Utah State University
Year: 2021

description: This paper examines the stock market reaction to banks that lobby relative to banks that did not lobby in the period around the November 9, 2016, U.S. presidential election. Using three different methods of event studies to calculate the cumulative average return, we find that lobbying in banks has a meaningful relationship to an abnormal increase in those firm’s stock prices. Then we attempt to control for both the systemic importance and size of these institutions by performing cross-sectional regressions that include matched size, and the systemic nature of the banks. The results suggest that a heavily regulated industry such as banking, can see a noteworthy impact from a strong lobbying strategy.

description: In this paper, an approach to facilitate the treatment with variabilities in system families is presented by explicitly modelling variants. The proposed method of managing variability consists of a variant part, which models variants and a decision table to depict the customisation decision regarding each variant. We have found that it is easy to implement and has advantage over other methods. We present this model as an integral part of modelling system families.

title: Pharmaceutical Stock Prices around Medicare Part D Expansion
Creators: name: Powell, Spencer
Publisher: name: Utah State University
Year: 2021

description: On January 1, 2006 Medicare part D expanded, giving prescription coverage to many Americans. This event offers an interesting question regarding market efficiency, specifically because Medicare expansion was introduced into congress as far back as 1999. Because Medicare part D affected pharmaceutical drug coverage, this study focuses specifically on securities in the pharmaceutical industry. Following an efficient market hypothesis, we would expect to see significant abnormal returns in the post event window, anticipating the legislations effect on demand within the industry. Results showed significant abnormal returns in post-event window, but not in the pre-event window. The returns in the post-event window were both statically and economically significant. This suggests that most of the abnormal returns stemmed from a reaction after the implementation instead of anticipating the implementation.

In the presence of a light CP-odd Higgs scalar, these can differ considerably from the MSSM. We discuss the amount of these contributions in regions of the parameter space of the general NMSSM compatible with constraints from B physics. In the mSUGRA-like cNMSSM, constraints from (g-2)_mu prefer regions in parameter space corresponding to a low SUSY breaking scale.

description: Arc- and tail-like structures associated with disks around Herbig stars can be a consequence of infall events occurring after the initial collapse phase of a forming star. An encounter event of gas with a star can lead to the formation of a second-generation disk after the initial protostellar collapse phase. Additionally, observations of shadows in disks can be well described by a configuration of misaligned inner and outer disk, such that the inner disk casts a shadow on the outer disk. Carrying out altogether eleven 3D hydrodynamical models with the moving mesh code AREPO, we test whether a late encounter of an existing star-disk system with a cloudlet of gas can lead to the formation of an outer disk that is misaligned with respect to the primordial inner disk. Our models demonstrate that a second-generation disk with large misalignment with respect to an existing primordial disk can easily form if the infall angle is large. The second-generation outer disk is more eccentric, though the asymmetric infall also triggers eccentricity of the inner disk of $e\approx 0.05$ to $0.1$. Retrograde infall can lead to the formation of counter-rotating disks and enhanced accretion. As the angular momentum of the inner disk is reduced, the inner disk shrinks and a gap forms between the two disks. The resulting misaligned disk system can survive for $\sim 100$ kyr or longer without aligning each other even for low primordial disk masses given an infall mass of $\sim 10^{-4}$ M$_{\odot}$. A synthetic image reveals shadows in the outer disk similar to the ones observed in multiple transition disks that are caused by the misaligned inner disk. We conclude that late inclined infall onto a star-disk system leads to the formation of a misaligned outer disk. Infall might therefore be responsible for observations of shadows in at least some transition disks.

Coefficient of restitution for normal and oblique impacts

description: Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)
The coefficient of restitution (COR) is an important metric for describing the liveliness of softballs. Only softballs that meet COR regulations set forth by governing softball associations are allowed in play. This is done for fairness as well as safety for the players. Softballs are tested in accordance with ASTM F1887-14. This standard states that a softball is projected normally onto a flat rigid wall at 60 mph and the rebound speed is measured with light gates. COR is found from the ratio of the outbound speed to the inbound speed. However, softball is a game in which players actively try to put spin on the ball; whether it’s a pitcher adding spin to their pitches with different grips or releases to try and outsmart the batter, or batters aiming to hit the ball in a way that optimizes backspin allowing the ball to travel farther. Therefore, in game situations, a ball will rarely impact a surface straight on with no spin, instead it is likely to bounce obliquely. There has been limited research on oblique impacts of softballs, as most of the focus has been limited to the normal direction. This research aims to study high speed oblique impacts of softballs.

description: Predators frequently must detect and localize their prey in challenging environments. Noisy environments have been prevalent across the evolutionary history of predator–prey relationships, but now with increasing anthropogenic activities noise is becoming a more prominent feature of many landscapes. Here, we use the gleaning pallid bat, Antrozous pallidus, to investigate the mechanism by which noise disrupts hunting behaviour. Noise can primarily function to mask—obscure by spectrally overlapping a cue of interest, or distract—occupy an animal's attentional or other cognitive resources. Using band-limited white noise treatments that either overlapped the frequencies of a prey cue or did not overlap this cue, we find evidence that distraction is a primary driver of reduced hunting efficacy in an acoustically mediated predator. Under exposure to both noise types successful prey localization declined by half, search time nearly tripled, and bats used 25% more sonar pulses than when hunting in ambient conditions. Overall, the pallid bat does not seem capable of compensating for environmental noise. These findings have implications for mitigation strategies, specifically the importance of reducing sources of noise on the landscape rather than attempting to reduce the bandwidth of anthropogenic noise.

description: In biomimetic and biological systems, interactions between surfaces are often mediated by adhesive molecules, nanoparticles, or colloids dispersed in the surrounding solution. We present here a general, statistical-mechanical model for two surfaces that interact via adhesive particles. The effective, particle-mediated interaction potential of the surfaces is obtained by integrating over the particles' degrees of freedom in the partition function. Interestingly, the effective adhesion energy of the surfaces exhibits a maximum at intermediate particle concentrations, and is considerably smaller both at low and high concentrations. The effective adhesion energy corresponds to a minimum in the interaction potential at surface separations slightly larger than the particle diameter, while a secondary minimum at surface contact reflects depletion interactions. Our results can be generalized to surfaces with specific receptors for solute particles, and have direct implications for the adhesion of biomembranes and for phase transitions in colloidal systems.

Traditionally, surfboard design has been guided by the intuition of surfboard shapers, who either tested their creations in the water or relied on feedback from professional surfers. This artisanal approach, while steeped in tradition, lacks scientific precision. Recognizing the need for a more systematic approach, we propose an automated workflow using multiphase CFD simulations. These simulations enable us to study the fluid dynamics around surfboards, offering a scientific perspective on their hydrodynamic performance. This paper presents a preliminary comparison of CFD simulation results for three surfboard designs with varying tail rocker profiles. The rocker of a surfboard is the curvature of the bottom part of the profile of the board, measured from the tail to the nose. As a general guideline, boards with lower tail rockers are expected to have less resistance and generate more lift, leading to higher speed but less manoeuvrability. We show how different tail rocker profiles impact essential performance metrics, such as lift, drag, and pressure coefficient. We also aim to demonstrate how a more data-driven approach can give additional insight into the performance and potentially improve surfboard design.

description: The benefits and properties of porous asphalt (PA) pavements were initially summarised based on a literature review. Further, the influence of modifications using different combinations of carbon and cellulose fibre was shown by laboratory tests carried out by the Institute of Transportation Infrastructure Engineering of Technical University of Darmstadt. The main focus of this paper is to characterise the permeability of porous asphalt by using asphalt petrology, a geology-based method adapted for analysing the internal structure of asphalt samples. This method introduces new parameters, such as the void surface area subdivided into classes. These parameters allow further attributes of the asphalt to be inferred, as was shown for vertical permeability in this paper. To this end, a function was successfully developed and applied to predict the permeability of asphalt specimens.

description: In Q2 2024, the DDI Alliance Executive Board developed a Strategic Plan for 2024 - 2027. This lays out the strategic priorities for the DDI Alliance over the next three years and on which areas work should be focused. The purpose of the Scientific Work Plan is to complement this document by outlining more concrete outcomes, which should cascade down to Working Groups for specific, local implementation. The DDI Technical Committee has a special approval and QA role in this apparatus, in that it takes responsibility for ensuring technical alignment and best practice for DDI products, both for consistent product development practices and harmonised infrastructure.

Having defined these concrete goals, the Scientific Board’s primary purpose is to be a proactive enabler for their implementation by Working Groups. Each Working Group shall have a named contact within the Scientific Board. As well as providing support to the working group, each contact should formally report back to the Scientific Board on a regular basis on the status of each Working Group’s activities and how their work is helping deliver on the Scientific Work Plan.

In summary, the philosophy of approach is that the Executive Board sets the tone and the priorities for the DDI Alliance (as well as having special responsibility for Finance and Marketing); the Scientific Board defines and supports the delivery of concrete goals by the Working Groups; Technical Committee oversees standards and technical best practice across all working groups and products; finally, working groups implement the Scientific Work Plan and should have the freedom to progress those goals in ways that work for their local community of interest.

The two most recent World Cup footballs, both created by adidas, are Al Rihla, used in Qatar for the 2022 FIFA World Cup for men, and Oceaunz, used in Australia and New Zealand for the 2023 FIFA World Cup for women. Both balls possess the same surface texturing and panel shapes. Eight of the 20 panels are triangular shaped and small in size compared to the other 12 panels. The balls have a polyurethane skin, and though the two balls have differentsurface coloring, water-based inks and glues were used. The goal of the work presented here was to use a wind tunnel to ascertain various aerodynamic properties of Al Rihila and Oceaunz, and then determine if the two seemingly equivalent balls are indeed aerodynamically equivalent. The manufacturer claims such equivalence, but such a claim can only be made in the context of experimental errors, both on the manufacturing side and on the wind-tunnel-testing side.

description: The phenomenon of trapping broad spectrum of light is known as `rainbow trapping' and achieved using all-dielectric, hybrid metallo-dielectric or all-metallic configurations. In the latter cases, unavoidable ohmic losses result in sub-picosecond trapped-mode lifetimes. For all practical purposes, novel strategies are required to be devised for trapping and subsequently, releasing broadband electromagnetic (em) field with lifetime > 1 ps. We present a rainbow trapping configuration using the excitation of multiple optical Tamm (OT) modes in an one-dimensional chirped photonic crystal (PC) designed for adiabatically coupling counter-propagating modes. In the geometry, the multiple pi phase jumps enable excitation of OT modes when a thin plasmon-active metal is placed adjacent to the terminating layer of chirped-PC (CPC). The strongly localized OT resonances are spatially separated in the chirped-PC geometry and their group-velocities reduce to as low as 0.17c. The time-domain simulations elucidate localization takes place in the dielectric sections of CPC which manifest into lifetimes 3 ps.

We study the void induced hyperbolicity, that is the deviation of the photon beams propagating the voids, taking into account the redshift dependence of the void size indicated by the observational surveys. The cumulative image distortion parameter is obtained for the case of a sequence of variable size voids and given underdensity parameters. The derived formulae applied along with those of redshift distortion ones, enable one to trace the number and the physical parameters of the line-of-sight voids from the analysis of the distortion in the galactic surveys.}

description: Parallel algorithms for solving geometric problems on two array processor models the mesh-connected computer (MCC) and a two-dimensional systolic array are presented. We illustrate a recursive divide-and-conquer paradigm forMCC algorithms by presenting a time-optimal solution for the problem of finding the nearest neighbors of a set of planar points represented by their Cartesian coordinates. The algorithm executes on a √n • √n MCC, and requires an optimal O(√n) time. An algorithm for constructing the convex hull of a set of planar points and an update algorithm for the disk placement problem on an n2/3 x n2/3 two-dimensionalsystolic array are presented. Both these algorithms require O(n2/3) time steps. The advantage of the systolic solutions lies in their suitability for direct hardware implementation.

Publisher: name: Utah State University
Year: 2021

description: The speech of individuals with autism spectrum disorder (ASD) has been perceptually judged as less clear and articulate than the speech of their typically developing (TD) peers. Some evidence suggests that reduced articulatory precision may contribute to negative listener impressions of individuals with ASD. Using an objective, holistic measure of articulatory precision, findings from a corpus of 900 semi-structured speech samples indicate that individuals with ASD produced speech with reduced articulatory precision compared to TD peers. In both TD populations and populations with ASD, children were less precise than adults. While more research is required to substantiate these preliminary findings, articulatory precision may be a potential avenue of further investigation as a diagnostic speech marker for ASD.

description: In the last year, the outbreak of COVID-19 has deployed computer vision and machine learning algorithms in various fields to enhance human life interactions. COVID-19 is a highly contaminated disease that affects mainly the respiratory organs of the human body. We must wear a mask in this situation as the virus can be contaminated through the air and a non-masked person can be affected. Our proposal deploys a computer vision and deep learning framework to recognize face masks from images or videos. We have implemented a Boundary dependent face cut recognition algorithm that can cut the face from the image using 27 landmarks and then the preprocessed image can further be sent to the deep learning ResNet50 model. The experimental result shows a significant advancement of 3.4 percent compared to the YOLOV3 mask recognition architecture in just 10 epochs.

description: Point feature labeling is a classical problem in cartography and GIS that has been extensively studied for geospatial point data. At the same time, word clouds are a popular visualization tool to show the most important words in text data which has also been extended to visualize geospatial data (Buchin et al. PacificVis 2016). In this paper, we study a hybrid visualization, which combines aspects of word clouds and point labeling. In the considered setting, the input data consists of a set of points grouped into categories and our aim is to place multiple disjoint and axis-aligned rectangles, each representing a category, such that they cover points of (mostly) the same category under some natural quality constraints. In our visualization, we then place category names inside the computed rectangles to produce a labeling of the covered points which summarizes the predominant categories globally (in a word-cloud-like fashion) while locally avoiding excessive misrepresentation of points (i.e., retaining the precision of point labeling). We show that computing a minimum set of such rectangles is NP-hard. Hence, we turn our attention to developing heuristics and exact SAT models to compute our visualizations. We evaluate our algorithms quantitatively, measuring running time and quality of the produced solutions, on several artificial and real-world data sets. Our experiments show that the heuristics produce solutions of comparable quality to the SAT models while running much faster.

description: Unification is a pattern matching operation very frequently used in Artificial Intelligence. Logic and PROLOG interpreters and theorem provers heavily rely on unification since its beginning, unification has suffered from a slow execution. The execution time of logic programs and other programs based on unification can be significantly reduced by improving the performance of the unification operation. In this paper, we introduce a parallel unifications coprocessor for speeding up the unification algorithm. The machine is simulated at the register transfer level and the simulation results as well as performance comparisons with two serial unifications co processors are presented.
Negative Elliptic Flow of $J/ψ$'s: A Qualitative Signature for Charm Collectivity at RHIC

description: We discuss one of the most prominent features of the very recent preliminary elliptic flow data of $J/Ψ$ meson from the PHENIX collaboration \cite{Silvestre:2008tw}. Even within the the rather large error bars of the measured data a negative elliptic flow parameter ($v_2$) for $J/Ψ$ in the range of $p_T=0.5-2.5 \GeV/c$ is visible. We argue that this negative elliptic flow at intermediate $p_T$ is a clear and qualitative signature for the collectivity of charm quarks produced in nucleus-nucleus reactions at RHIC. Within a parton recombination approach we show that a negative elliptic flow puts a lower limit on the collective transverse velocity of heavy quarks. The numerical value of the transverse flow velocity $β_T$ for charm quarks that is necessary to reproduce the data is $β_T(charm)\sim 0.55-0.6c$ and therefore compatible with the flow of light quarks.

description: A charged parallel plate capacitor will create particle-antiparticle pairs by the Schwinger process and discharge over time. We consider the full quantum discharge process in 1+1 dimensions including backreaction, when the electric field interacts with massless charged fermions. We recover oscillatory features in the electric field observed in a semiclassical analysis and find that the amplitude of the oscillations falls off as t^{-1/2} and that stronger coupling implies slower decay. Remarkably, Ohm's law applies to the vacuum and we evaluate the quantum electrical conductivity of the vacuum to be e/π^{1/2}, where e is the fermionic charge. Similarities and differences with black hole evaporation are mentioned.

title: A Collection for a Better Misunderstanding
Creators: name: Smeltzer, Mark
Publisher: name: Utah State University
Year: 2021

description: What if being understood becomes even more dreadful than being isolated? This collection of poetry stands between two extremes, using form and language to reflect the struggle of living on a continuum between being understood and being alone. By echoing the direct style of poets like Charles Bukowski and Mark Strand, as well as more abstract figures like May Swenson and Sylvia Plath, this collection asserts that the contradictions we carry can coexist, and even complement one another. Part One features original poetry that relies on the senses to recover old memories. A direct style in Part One seeks to gain common ground with the reader. Part Two, however, drifts away from this goal in favor of abstraction. As each poem adopts more unconventional forms, those forms work to reflect an alienated mind.

description: A parallel algorithm for finding the longest common subsequence of two strings is presented.Our algorithm is executed on r processors, with r equal to the total number of pairs of positionsat which two symbols match. Given two strings of length m and n respectively, m ≤ n, withpreprocessing allowed, our algorithm achieves O(log⍴ log2n) time complexity where ⍴ is the longestcommon subsequence. Fast computing of Longest-Common-Subsequence is made possible due tothe exploiting of the parallelism.

description: New non-linear, spatially periodic, long wavelength electrostatic modes of an electron fluid oscillating against a motionless ion fluid (Langmuir waves) are given, with viscous and resistive effects included. The cold plasma approximation is adopted, which requires the wavelength to be sufficiently large. The pertinent requirement valid for large amplitude waves is determined. The general non-linear solution of the continuity and momentum transfer equations for the electron fluid along with Poisson's equation is obtained in simple parametric form. It is shown that in all typical hydrogen plasmas, the influence of plasma resistivity on the modes in question is negligible. Within the limitations of the solution found, the non-linear time evolution of any (periodic) initial electron number density profile n_e(x, t=0) can be determined (examples). For the modes in question, an idealized model of a strictly cold and collisionless plasma is shown to be applicable to any real plasma, provided that the wavelength lambda >> lambda_{min}(n_0,T_e), where n_0 = const and T_e are the equilibrium values of the electron number density and electron temperature. Within this idealized model, the minimum of the initial electron density n_e(x_{min}, t=0) must be larger than half its equilibrium value, n_0/2. Otherwise, the corresponding maximum n_e(x_{max},t=tau_p/2), obtained after half a period of the plasma oscillation blows up. Relaxation of this restriction on n_e(x, t=0) as one decreases lambda, due to the increase of the electron viscosity effects, is examined in detail. Strong plasma viscosity is shown to change considerably the density profile during the time evolution, e.g., by splitting the largest maximum in two.

Evidence for the naphthalene cation in a region of the interstellar medium with anomalous microwave emission

description: We report high resolution spectroscopy of the moderately reddened (A$_V$=3) early type star Cernis 52 located in a region of the Perseus molecular cloud complex with anomalous microwave emission. In addition to the presence of the most common diffuse interstellar bands (DIBs) we detect two new interstellar or circumstellar bands coincident to within 0.01% in wavelength with the two strongest bands of the naphthalene cation (C$_{10}$H$_{8}^+$) as measured in gas-phase laboratory spectroscopy at low temperatures and find marginal evidence for the third strongest band. Assuming these features are caused by the naphthalene cation, from the measured intensity and available oscillator strengths we find that 0.008 % of the carbon in the cloud could be in the form of this molecule. We expect hydrogen additions to cause hydronaphthalene cations to be abundant in the cloud and to contribute via electric dipole radiation to the anomalous microwave emission. The identification of new interstellar features consistent with transitions of the simplest polycyclic aromatic hydrocarbon adds support to the hypothesis that this type of molecules are the carriers of both diffuse interstellar bands and anomalous microwave emission.

description: Debris disk is a catch-all term that can be used to refer to any component of a planetary system which is not an actual planet. In the Solar System this refers to the asteroids and comets in the Asteroid and Kuiper belts as well as the dust and gas derived from them, such as the zodiacal cloud. Studying the structure of extrasolar debris disks provides unique constraints on the underlying planetary system and on the processes of planet formation and protoplanetary disk evolution. Debris disks also have important implications for processes affecting the planets, such as impact events that may strip an atmosphere or deliver volatiles. Their presence or absence also has consequences both positive and negative for the detectability of exoplanets in the system. Here I describe five of the most important ways in which debris disks will contribute to our understanding of extrasolar planetary systems in the coming years.

Knowledge of results and the perceptual trace
Creators: name: Stafford, Eric Michael
Publisher: name: University of British Columbia
Year: 2010

description: An experiment was designed to test the role of knowledge of results (KR) in perceptual trace (PT) development with KR temporal delay intervals and presence or absence of KR as independent variables. Each of three groups of 10 Ss_ per group had a specific arrangement of KR temporal delay intervals such that over all groups there were two KR delay intervals of 1.0 and 30.0 seconds, two post-KR delay intervals of 10.0 and 39.0 seconds and two intertrial intervals (ITI) of 11.0 and 40.0 seconds. All groups performed a linear positioning task over three phases of responding in order to vary the presence or absence of KR. Two hypotheses were tested. Hypothesis 1, which stated that the post-KR delay interval is the locus of post-KR phase response bias, was not supported by the results. However, there was a tentative finding that the KR phase ITI is the locus of post-KR phase response bias, which supports both the concept of a functioning,PT and the concept that the PT is formed solely from response-produced feedback (FB). Hypothesis 2, which stated that KR does not permanently affect response variability, was supported by the results. Response variability was the same prior to (i.e., pre-KR phase) and following (i.e., post-KR phase) the presentation of KR.
