Background. Gait characteristics extracted from trunk accelerations during daily life locomotion are complementary to questionnaire- or laboratory-based gait and balance assessments and may help to improve fall risk prediction. Objective. The aim of this study was to identify gait characteristics that are associated with self-reported fall history and that can be reliably assessed based on ambu...

Some of the factors that influence the persistence of pesticides are common to both plants and soils. These are, firstly, the characteristics of the pesticide, including its over-all stability either as parent compound or metabolites, its volatility, solubility, formulation, and the method and site of application. A second group includes the environmental factors, particularly temperature, prec...

CONTEXT Dynamic postural stability is important for injury prevention, but little is known about how lower-extremity musculoskeletal characteristics (range of motion [ROM] and strength) contribute to dynamic postural stability. Knowing which modifiable physical characteristics predict dynamic postural stability can help direct rehabilitation and injury-prevention programs. OBJECTIVE To determ...

ipad gene is amongst key genes in shigella invasion, known as an antigen. pa20 protein of bacillus anthracic can be separated from native pa protein during the infection and can be found in the serum of the infected patients and make it possible to diagnose the disease. ctxb, a known immune adjuvant, enhances the immunogenicity and is mainly used for the production of recombinant vaccines as a ...

BACKGROUND DNA methylation is an epigenetic mechanism that has been increasingly investigated in observational human studies, particularly on blood leukocyte DNA. Characterizing the degree and determinants of DNA methylation stability can provide critical information for the design and conduction of human epigenetic studies. METHODS We measured DNA methylation in 12 gene-promoter regions (APC...

This paper deals with the L2 stability of a shape memory alloy actuated position control system, based on a single wire under constant axial load. Presuming a controller has certain speci c dissipativity characteristics, it is shown that system stability can be guaranteed for a large class of controllers. In particular, the results can be used to show stability under approximated PID, PI and PD...

Relation between position resolution of haptic device and stability problem is discussed in this paper. Based on virtual wall model and passive characteristics of contact interaction, violation of passive dynamic criteria and energy accumulation of motor output are proved to be the factors that influence system stability. Influence of device parameter on stability is discussed and the criterion...

This paper investigates the problem of robust stability of uncertain linear discrete-time system over network with bounded packet loss. A new Lyapunov functional is constructed. It can more fully utilize the characteristics of the packet loss; hence the established stability criterion is more effective to deal with the effect of packet loss on the stability. Numerical examples are given to illu...

This paper examines a model of multi-jurisdiction formation where individuals’ characteristics are uniformly distributed over a finite interval. Every jurisdiction locates a public facility and distributes its cost equally among the residents. We consider two notions of stability: Nash stability and its refinement local Nash stability, and examine the existence and characterization of stable pa...
