Introduction. The application of binary-reflected (mirror, reflexive) Gray codes for solving combinatorial problems with pseudo-Boolean functions (polynomials from Boolean variables) is considered. A recursive Ehrlich algorithm given generating a sequence lines n-bit codes, in which each subsequent line differs the previous one by only digit (bit). As an example effectiveness use these solution...

STUDY OBJECTIVE We determine the number and location of freestanding emergency departments (EDs) across the United States and determine the population characteristics of areas where freestanding EDs are located. METHODS We conducted a systematic inventory of US freestanding EDs. For the 3 states with the highest number of freestanding EDs, we linked demographic, insurance, and health services...

The coronavirus disease (COVID-19) pandemic has triggered and accelerated the shift of firms businesses to adopt flexible alternative work arrangements such as teleworking or working from home (WFH) set-ups. To effectively transition ‘new normal’ work, this paper measures telework potential jobs degree which a job can be feasibly done at offsite. Using task-based framework, constructs continuou...

The explosive growth of multimedia data on the Internet has magnified challenge information retrieval. Multimedia usually emerges in different modalities, such as image, text, video, and audio. Unsupervised cross-modal hashing techniques that support searching among multi-modal have gained importance large-scale retrieval tasks because advantage low storage cost high efficiency. Current methods...

BACKGROUND Inclusion of information about a patient's work, industry, and occupation, in the electronic health record (EHR) could facilitate occupational health surveillance, better health outcomes, prevention activities, and identification of workers' compensation cases. The US National Institute for Occupational Safety and Health (NIOSH) has developed an autocoding system for "industry" and "...

for a finite field $mathbb{f}_q$, the bivariate skew polynomial ring $mathbb{f}_q[x,y;rho,theta]$ has been used to study codes cite{xh}. in this paper, we give some characterizations of the ring $r[x,y;rho,theta]$, where $r$ is a commutative ring. we investigate 2-d skew $(lambda_1,lambda_2)$-constacyclic codes in the ring $r[x,y;rho,theta]/langle x^l-lambda_1,y^s-lambda_2rangle_{mathit{l}}.$ a...

This paper investigates the impact of foreign direct investment (FDI) on performance companies in low- and high-technologically intensive industries manufacturing sector EU member countries, using datasets covering period between 2010 2020. The were selected according to High-tech classification based NACE Rev.2 at 2-digit codes. our study was measured turnover. We used a set independent variab...

In this paper, we examine the potential of using a thermal camera to recover codes typed into keypads in a variety of scenarios. This attack has the advantage over using a conventional camera that the codes do not need to be captured while they are being typed and can instead be recovered for a short period afterwards. To get the broadest sense of how effective such an attack might be, we consi...
