Proposed Libyan Guidelines for the Management of Inpatient Hyperglycemia with Corona Virus-19 (COVID-19) Infection

Serious hyperglycemia is one of the manifestations of COVID-19 infection which increase patient morbidity and mortality especially in patient requiring hospitalization. Consequently, many protocols and algorithms for hospitalized patients with COVID-19 induced hyperglycemia based mainly on recent studies and previous evidence on non-COVID-19 patients were published. Of note nearly all guidelines released by the different COVID-19 committees in Libya don’t include a clear focus on management of in-patient hyperglycemia and maybe this plays a pivotal role in increase our COVID-19 in-hospital mortality. I proposed a simplified approach depending on the released international guidelines to be easily implemented by Libyan health care staff caring about COVID-19 patients and hoping to be accepted by our National Diabetes Committee.

Proposed Wave Momentum Source for Generating the 22-Year Solar Cycle

For the 22-year solar cycle oscillation there is no external time dependent source. A nonlinear oscillation, the solar cycle must be generated internally, and Babcock-Leighton models apply an artificial nonlinear source term that can simulate the observations—which leaves open the question of the actual source mechanism for the solar cycle. Addressing this question, we propose to take guidance from the wave mechanism that generates the 2-year Quasi-biennial Oscillation (QBO) in the Earth atmosphere. Upward propagating gravity waves, eastward and westward, deposit momentum to generate the observed zonal wind oscillation. On the Sun, helioseismology has provided a thorough understanding of the acoustic p-waves, which propagate down into the convective envelope guided by the increasing temperature and related propagation velocity. Near the tachocline with low turbulent viscosity, the waves propagating eastward and westward can produce an axisymmetric 22-year oscillation of the zonal flow velocities that can generate the magnetic solar dynamo. Following the Earth model, waves in opposite directions can generate in the Sun wind and magnetic field oscillations in opposite directions, the proposition of a potential solar cycle mechanism.

Integration of Chinese Medicine and Western Medicine in Clinical Practice(Patient Care):Past,Present,and A Proposed Model for the Future

Historic Background Chinese medicine （CM） has over 2,000 years of history in China and was the only health care system providing care for Chinese prior to the introduction of Western medicine （WM） into China. WM was slowly introduced into China by missionaries from the middle 17th century to the beginning of the 19th century. By 1840, WM began to take root in China. Western hospitals, clinics, medical schools and nursing schools spread rapidly throughout the country. At that time, with the might and power portrayed by Western countries,

A proposed approach for detecting terahertz pulses by using double few-cycle laser pulses with opposite carrier envelope phases

Previous research shows that few-cycle laser（FCL） pulses with low energy and without a bias field can be used to coherently detect terahertz（THz） pulses. As we know, it is very difficult to stabilize the carrier envelope phase（CEP） of FCL pulses, i.e., there are some random fluctuations for the CEP. Here we theoretically investigate the influence of such instability on the accuracy of THz detection. Our results show that although there is an optimum CEP for THz detection, the fluctuations of the CEP will lead to terrible thorns on the detected THz waveform. In order to solve this problem, we propose an approach using two few-cycle laser pulses with opposite CEPs, i.e., their CEPs are differed by π.

AN ALGORITHM PROPOSED FOR BUSY-PERIOD SUBCOMPONENT ANALYSIS OF BULK QUEUES

This paper presents an algorthmic procedure for a busy-period subcomponent analysis of bulkqueues. A component of interest for many server queues is the period tto reduce congestion froma level k to level k-1. For an M(x)/M/c system with the possibility of total or partial rejection ofbatches, it is demonstrated that the expected length of busy periods, the proportion of delayed batchand the steady state queue length probabilities can be easily obtained. The procedure is based on thenested partial sums and monotonic properties of expected lengths of the busy periods.

Phase invariance in a recently proposed common-path laser interferometer

This study shows that the principle of a recently proposed connnon-path laser interferometer containing a planar grating is nonexistent and apparently caused by a mathematical derivation error. Both p- and s-polarized beams ill the proposed setup experience once the ＋lst-order diffraction and once the lst-order diffraction by tile grating. As a result, the phase of each beam remains unchanged and the interference fringes formed by the two beams are not expected to move when the grating is translated in the grating vector direction. We perform an experiment to confirm this prediction. Both our analysis and experimental observation cast doubt on the experimental results of the authors who proposed the interferometer.
