Function Maximization with Dynamic Quantum Search
Finding the maximum value of a function in a dynamic model plays an important
role in many application settings, including discrete optimization in the
presence of hard constraints. We present an iterative quantum algorithm for
finding the maximum value of a function in which prior search results update
the acceptable response. Our approach is based on quantum search and utilizes a
dynamic oracle function to mark items in a specified input set. As a
realization of function optimization, we verify the correctness of the
algorithm using numerical simulations of quantum circuits for the Knapsack
problem. Our simulations make use of an explicit oracle function based on
arithmetic operations and a comparator subroutine, and we verify these
implementations using numerical simulations up to 30 qubits.Comment: 10 pages, 2 figures, submitted to Workshop on Quantum technology and

Employment loss and food insecurity - race and sex disparities in the context of COVID-19
INTRODUCTION: Applying an intersectional framework, we examined sex and racial inequality in COVID-19-related employment loss (ie, job furlough, layoff, and reduced pay) and food insecurity (ie, quality and quantity of food eaten, food worry, and receipt of free meals or groceries) among residents in Saint Louis County, Missouri.
METHODS: We used cross-sectional data from adults aged 18 or older (N = 2,146), surveyed by using landlines or cellular phones between August 12, 2020, and October 27, 2020. We calculated survey-weighted prevalence of employment loss and food insecurity for each group (Black female, Black male, White female, White male). Odds ratios for each group were estimated by using survey-weighted binary and multinomial logistic regression models.
RESULTS: Black female residents had higher odds of being laid off, as compared with White male residents (OR = 2.61, 95% CI, 1.24-5.46). Both Black female residents (OR = 4.13, 95% CI, 2.29-7.45) and Black male residents (OR = 2.41, 95% CI, 1.15-5.07) were more likely to receive free groceries, compared with White male residents. Black female (OR = 4.25, 95% CI, 2.28-7.94) and White female residents (OR = 1.93, 95% CI, 1.04-3.60) had higher odds of sometimes worrying about food compared with White male residents. Black women also had higher odds of always or nearly always worrying about food, compared with White men (OR = 2.99, 95% CI, 1.52-5.87).
CONCLUSION: Black women faced the highest odds of employment loss and food insecurity, highlighting the disproportionate impact of COVID-19 among people with intersectional disadvantages of being both Black and female. Interventions to reduce employment loss and food insecurity can help reduce the disproportionately negative social effects among Black women

Requirements for Xenon International
This document defines the requirements for the new Xenon International radioxenon system. The output of this project will be a Pacific Northwest National Laboratory (PNNL) developed prototype and a manufacturer-developed production prototype. The two prototypes are intended to be as close to matching as possible; this will be facilitated by overlapping development cycles and open communication between PNNL and the manufacturer
