This paper presents a Class-D power amplifier for bandpass pulse width modulated (BP-PWM) and bandpass deltasigma modulated (BP-DSM) signals at 20 MHz. A 1-bit 6-th order topology is used in the ∆Σ-modulator. Integral noise shaping is used in the generation of the bandpass pulse width modulated signal. A two sided pulse width modulation is used with a 6-bit 4th-order noise shaper. The push-pull...

Background: Health benefits of vitamin D has been proved by a large number of studies, however, to the best of our knowledge there has been no study investigating the effect of mega dose of vitamin D on gestational diabetes mellitus (GDM). This study was the first to assess the effect of postpartum injection of mega dose of vitamin D on blood pressure (BP) in GDM. Methods: This is a randomized ...

There are inconsistent reports that the angiotensinogen (ATG) variant Met235-->Thr (T235) allele and angiotensin-converting enzyme (ACE) insertion/deletion (I/D) variants are associated with hypertension and related target organ damage. Both high blood pressure (BP) and abnormal diurnal BP variation patterns are related to target organ damage, but it is not known whether the above genetic varia...

Background: Bovine spongiform encephalopathy (BSE) is a prion disease that always fatal in cattle and considered an important risk factor for human health. Genetic polymorphisms alter proteins may be associated with susceptibility or resistance to infectious encephalopathy. Therefore, we investigated the distribution of 23 bp indel variant protein (PRNP) gene Jersey Turkey. Methods: A total 95 ...

Flexible Dual-TCP/UDP Streaming Protocol with Bitstream Prioritization (FDSP-BP) is a new method for streaming H.264-encoded High-definition (HD) video over wireless networks. This paper presents a novel technique to adaptively modify the Bitstream prioritization (BP) parameter based on network conditions. This technique selects the maximum BP value that satisfies the Transmission Control Proto...

The Tibetan Plateau (TP) is primarily influenced by the northern hemispheric middle latitude Westerlies and the Indian summer monsoon (ISM). The extent, long-distance effects and potential long-term changes of these two atmospheric circulations are not yet fully understood. Here, we analyse modern airborne pollen in a transition zone of seasonally alternating dominance of the Westerlies and the...

Herein, we report the fabrication of a novel heterojunction field-effect transistor (HJFET) based on two-dimensional graphene (Gr), molybdenum diselenide (MoSe2), and black phosphorus (BP) that is shielded using hexagonal boron nitride to prevent device degradation. We perform electrical optoelectronic characterizations Gr/n-MoSe2 Gr/n-MoSe2/p-BP heterojunctions. Heterojunction n-MoSe2/p-BP exh...

In this work, the electronic properties of BP and CSi Nano cones have been investigated by self-consistent reaction field (SCRF) method in water solvent at B3PW91/6-31G (d,p) level of DFT theory for study of  for interactions of 5-Fluorouracil Anticancer Drug with theses Nano cones. The percent of change of energy gap (%ΔEg) shows that the complex formation of 5-Fluorouracil with BP ...

BACKGROUND Vitamin D deficiency is a risk factor for hypertension. METHODS We assessed 8155 participants in a community-based program to investigate the association between serum 25-hydroxyvitamin D (25(OH)D) status and blood pressure (BP) and the influence of vitamin D supplementation on hypertension. Participants were provided vitamin D supplements to reach a target serum 25(OH)D > 100 nmol...
