The history of Tow–Thomas second-order filter is reviewed. Two alternative generation methods of the Tow–Thomas filter are discussed. The first is a generation method from the second-order passive RLC filter and the second is from the multiple feedbacks inverting low-pass filter using a single op amp. Several forms of the circuit are briefly reviewed. Passive and active compensation methods to ...

The sea surface temperature (SST) and enthalpy flux response to tropical cyclones (TCs) in the Kuroshio are investigated using 18-year observational datasets. statistical results show that maximum TC-induced SST cooling its occurrence time, recovery spatial patterns of anomaly, anomaly between warm core eddies (WCEs) typical oceanic water (i.e., eddy-free Kuroshio-free, TOW) varies considerably...

objective: there are disparities in mental health services (mhs) utilization within and between populations and several factors are studied as its potential correlates. identifying those correlates would help health policy makers to adjust service provision with characteristics of their community. to evaluate demographic, socioeconomic and system correlates of mhs utilization among married wome...

the present study aims at exploring the relation between long term memory and two teaching methods: research-centered teaching and customary lecturing. the promotion of exploratory thinking which is provoked in the research-centered teaching method is considered to lead to hypothetical research and analytical thinking among students. two separate courses in neurophysiology at tehran university ...

The true slime mold Physarum polycephalum, a single-celled amoeboid organism, is capable of efficiently allocating a constant amount of intracellular resource to its pseudopod-like branches that best fit the environment where dynamic light stimuli are applied. Inspired by the resource allocation process, the authors formulated a concurrent search algorithm, called the Tug-of-War (TOW) model, fo...

Pain is a life-long symptom in sickle cell disease (SCD) and a predictor of disease progression and mortality, but little is known about its molecular mechanisms. Here, we characterized pain in a targeted knockin mouse model of SCD (TOW mouse) that exclusively expresses human alleles encoding normal α- and sickle β-globin. TOW mice exhibited ongoing spontaneous pain behavior and increased sensi...

In today's mixed-model assembly production, there are two recent trends in particular, namely increasing vertical integration and the proliferation of product variety, which more and more shift focus to an e cient just-in-time part supply. In this context, many automobile manufacturers set up decentralized logistics areas referred to as supermarkets . Here, small tow trains are loaded with part...
