An optimised algorithm for ionized impurity scattering in Monte Carlo simulations

We present a new optimised model of Brookes-Herring ionized impurity scattering for use in Monte Carlo simulations of semiconductors. When implemented, it greatly decreases the execution time needed for simulations (typically by a factor of the order of 100), and also properly incorporates the great proportion of small angle scatterings that are neglected in the standard algorithm. It achieves this performance by using an anisotropic choice of scattering angle which accurately mimics the true angular distribution of ionized impurity scattering.Comment: 5 page

A GENERALIZED SUPPLY RESPONSE/FACTOR DEMAND MODEL AND ITS APPLICATION TO THE FEEDER CATTLE MARKET

The appropriate specification of expectations in empirical models of supply response or factor demand is discussed. A general model that admits both extrapolative and rational expectations is formulated and analyzed. The model is used to investigate the decision making process of cattle feeders by incorporating information on futures prices (as representations of rational forecasts) and lagged prices. The findings provide some evidence that cattle feeders form their expectations of future prices using both types of information.Demand and Price Analysis, Livestock Production/Industries,

A Preliminary Model for Selecting Aphasia Treatment Type Based on Cognitive Profile

Implementation of evidence-based practices requires models and faciltiators that allow clinicians to efficiently select from the most appropriate evidence-supported treatments for their patients.  This paper presents a preliminary clinical-decision making model for selecting aphasia treatments, based on the scientific evidence.  The four steps of the model include considerations for cognitive profile, functional contexts, impairments and/or strategies, and a menu of evidence-supported treatments.  Each of these four steps are founded on a rigorous literature review. Two illustrative cases are presented and future requirements for further testing of the model are discusse

The "Seen but Unnoticed" Vocabulary of Natural Touch: Revolutionizing Direct Interaction with Our Devices and One Another (UIST 2021 Vision)

This UIST Vision argues that "touch" input and interaction remains in its infancy when viewed in context of the seen but unnoticed vocabulary of natural human behaviors, activity, and environments that surround direct interaction with displays. Unlike status-quo touch interaction -- a shadowplay of fingers on a single screen -- I argue that our perspective of direct interaction should encompass the full rich context of individual use (whether via touch, sensors, or in combination with other modalities), as well as collaborative activity where people are engaged in local (co-located), remote (tele-present), and hybrid work. We can further view touch through the lens of the "Society of Devices," where each person's activities span many complementary, oft-distinct devices that offer the right task affordance (input modality, screen size, aspect ratio, or simply a distinct surface with dedicated purpose) at the right place and time. While many hints of this vision already exist (see references), I speculate that a comprehensive program of research to systematically inventory, sense, and design interactions around such human behaviors and activities -- and that fully embrace touch as a multi-modal, multi-sensor, multi-user, and multi-device construct -- could revolutionize both individual and collaborative interaction with technology.Comment: 5 pages.
