We use longitudinal survey data to compare the impacts of ‘emergency’ low traffic neighbourhoods (LTNs), set up during Covid-19, longer-standing LTNs. While sample sizes are small, both types LTNs had similar increases in active travel and improvements perceptions local environment for cycling (but no change most other aspects environment). Car tended decrease. This similarity suggests emergenc...

The warming of the Arctic climate is confirmed by changes in main hydrometeorological values atmosphere and ocean over a long period time, it most pronounced recent decades. Based on monthly average data from reanalysis NASA MERRA-2 satellite measurements, we studied air temperature, precipitation, wind speed region western part Russian (60°–75° N, 30°–85° E) 1980–2021. transition between 2000 ...

I discuss the physics reach of a fixed-target charm experiment which can reconstruct >10 charm decays, three orders of magnitude beyond the largest extant sample. Such an experiment may run at Fermilab shortly after the Year 2000. In addition to “programmatic” charm physics such as spectroscopy, lifetimes, and tests of QCD, this “Charm2000” experiment will have significant sensitivity to new ph...

The Image Reduction and Analysis Facility is a scientific image processing package widely used throughout the astronomical community. IRAF has been developed and distributed by the National Optical Astronomy Observatory in Tucson, Arizona since the early 1980’s. Other observatories and projects have written many dozens of layered external application packages. More than ten thousand journal art...

JPEG2000 is the new standard for the compression of still images. Its objective and subjective image quality performance is superior to existing standards. In this paper the Part I of the JPEG2000 standard is presented in brief, and its implementation complexity on different computer platforms is reported.

In the terms of operational calculus the probability characteristics of direct and reverse residual renewal time of alternating renewal process, where renewal time depends on life-time, are found. 1. Definitions, Motivations and Formulation of the Problem 1.1 According to [1] let’s consider a system which fails after random life-time X1 and is fully renewed after the lapse of random time Y1. Th...

Despite the enormous media coverage that the issue of year 2000 (Y2K) readiness has received in recent months, the focus of that coverage has been restricted almost exclusively to technological aspects. Non-technical issues have tended to be either ignored completely or given very little attention. Most importantly, not much is known about the organisational processes of preparing to face this ...

The purpose of this study was to compare three different intervals for a between sets rest period during a common isokinetic knee extension strength-testing protocol of twenty older Brazilian men (66.30 ± 3.92 yrs). The volunteers underwent unilateral knee extension (Biodex System 3) testing to determine their individual isokinetic peak torque at 60, 90, and 120°s(-1). The contraction speeds an...

Abstract This paper aims to explore the evolution of China’s foreign talent policy (FTP) and factors that contribute those changes. Selecting Beijing as a case study, this explores Beijing’s FTP divides it into three periods (1949–1978; 1978–2000; 2000 until now). It argues at point when system becomes more institutionalized, simplified measures are adopted. In particular, applies three-tier fr...
