Abstract This paper presents a low-power infrared motion detection system suitable for smart devices such as wearables. The SoC incorporates instrumentation chopper amplifiers (ICA), LPFs, ADCs, and a DSP. The low-noise ICAs amplify very low frequency μV-level thermopile outputs with 2.0 NEF and provide programmable gain modes. To reduce standby power the ICA uses lower current when the system ...

The Furstenberg–Sárközy theorem asserts that the difference set E?E of a subset E?N with positive upper density intersects image any polynomial P?Z[n] for which P(0)=0. Furstenberg's approach relies on correspondence principle and version Poincaré recurrence theorem, is derived from ergodic-theoretic result measure-preserving system (X,B,?,T) A?B ?(A)>0, one has c(A):=limN???1N?n=1N?(A?T?P(n)A)...

During electrophysiology study, mapping was performed using a 20 pole multielectrode catheter (MEC) via a retrograde aortic approach (Figure 1C). The baseline A–H and H–V intervals were 57 and 55 ms, respectively (Figure 1B, left). A wide QRS tachycardia identical to the clinical tachycardia was observed with cycle length of 320 ms, H–V interval of −30 ms (Figure 1B, right). This was consistent...

Crohn's disease (CD) is an inflammatory bowel disease characterized by an exaggerated immune response to commensal microbiota in the intestines of patients. Metagenomic studies have identified specific bacterial species and strains with increased prevalence in CD patients, amongst which is the adherent-invasive Escherichia coli (AIEC) strain LF82. AIEC strains express long polar fimbriae (LPF),...

Methods that are more cost-effective and objective are needed to detect important vegetation change within acceptable error rates. The objective of this research was to compare visual estimation to three new methods for determining vegetation cover in the sagebrush steppe. Fourteen management units at the US Sheep Experiment Station were identified for study. In each unit, 20 data collection po...

We investigated the role of the Salmonella typhimurium fimbrial operon formed by the genes lpfABCDE in infection of mice. A mutant in lpfC, the gene encoding the fimbrial outer membrane usher, had an approximately 5-fold increased 50% lethal dose when administered orally to mice. When mice were infected with a mixture of the lpfC mutant and isogenic wild-type S. typhimurium, the lpfC mutant was...

Introduction Osteoporosis is a degenerative disease characterized by bone loss, and it is associated with significant socioeconomic impact [1]. Trabecular bone analysis is important in clinical studies of osteoporosis, and magnetic resonance imaging (MRI) allows for non-invasive 3D quantitative trabecular bone assessment. MRI of osteoporosis-related anatomical locations are generally acquired w...

In this study, we explained the effects of compression garment and electrostimulation on athletes' recovery period by evaluating blood lactate and isokinetic peak torque parameters. Twenty volunteers (15.55± 0.51 yr) were included to study. At recovery period, blood samples was taken for lactate values at 0th, 3rd, 5th, 15th, 30th min. The isokinetic strength test was performed on right ankle a...
