BACKGROUND Individuals with reading disability or individuals with autism spectrum disorder (ASD) are characterized, respectively, by their difficulties in reading or social communication, but both groups often have impaired phonological working memory (PWM). It is not known whether the impaired PWM reflects distinct or shared neuroanatomical abnormalities in these two diagnostic groups. METH...

OBJECTIVES To explore whether people's organ donation consent decisions occur via a reasoned and/or social reaction pathway. DESIGN We examined prospectively students' and community members' decisions to register consent on a donor register and discuss organ donation wishes with family. METHOD Participants completed items assessing theory of planned behaviour (TPB; attitude, subjective norm...

T lymphocytes were derived by E rosetting from the peripheral blood (PB) and bone marrow (BM) of 15 patients with chronic granulocytic leukemia (CGL) in the chronic phase of their disease. T cells were also obtained from 12 healthy individuals. T cells were incubated overnight either in culture medium (RPMI) or RPMI plus pokeweed mitogen (PWM). The supernatants were then recovered and the cells...

A study of the kinetics of RNA and DNA synthesis in PWM-stimulated lymphocytes revealed that RNA synthesis preceded the onset of DNA synthesis by approximately 24 hr and that DNA synthesis and transformation was maximal between 66 to 78 hr. Histochemical and radioautographic studies on PWM stimulated cultures indicated that at 72 hr 50 to 60% of the cell population had been transformed by PWM, ...

This paper provides analytical and graphical tools for the study, performance evaluation, and design of the modern carrier based PWM methods which are widely employed in PWM-VSI drives. Simple techniques for generating the modulation waves of the high performance PWM methods are described. The two most important modulator characteristics, the current ripple and the switching losses are analytic...

Voltage and current source inverter are widely used in electrical motor drives. In this drives, DC voltage (or current) are usually provided from phase control or line commutation rectifiers. Because of disadvantage & limitation of this converter, some new topologies are presented in advanced drive such as PWM rectifier. Thanks to well known capabilities of PWM rectifier, classical converter’s ...

In this paper, a generalized discontinuous pulsewidth modulation (GDPWM) method with superior high modulation operating range performance characteristics is developed. An algorithm which employs the conventional space-vector PWM method in the low modulation range, and the GDPWM method in the high modulation range, is established. As a result, the current waveform quality, switching losses, volt...

In this paper, the overmodulation region voltagegain characteristics and waveform quality of carrier-based pulsewidth-modulated (PWM) methods are investigated. Through detailed analytical study, voltage-gain characteristics are extracted independent of carrier frequency. The influence of blanking time and minimum pulsewidth (MPW) control on the inverter gain characteristics are studied and show...

objective(s): systemic candidiasis is an infection of candida albicans (c. albicans) causing disseminated disease and sepsis, invariably when host defenses are compromised. we investigated the histopathological changes as well as the lymphoproliferative responses and cytokine production of splenic cells after stimulation with concanavalin a (con a) and pokeweed mitogen (pwm) in mice with dissem...

Although uniformly sampled pulse width modulation (UPWM) represents a very efficient digital audio coding scheme for digitalto-analog conversion and full-digital amplification, it suffers from strong harmonic distortions, as opposed to benign nonharmonic artifacts present in analog PWM (naturally sampled PWM, NPWM). Complete elimination of these distortions usually requires excessive oversampli...
