Dealing with Asymmetrical Abel Inversion Using Fourier-Bessel Expansions

A new method is presented for dealing with asymmetrical Abel inversion in this paper.We separate the integrated quantity into odd and even parts using Yasutomo's method. The asymmetric local value is expressed as the product of a weight function and a symmetric local value. The symmetric distribution is expanded into Fourier-Bessel series. The coefficients of the series are determined by the use of a least-square-fitting method.

Role of mental health professionals in dealing with the stigma attached to COVID-19

The stigma associated with the disease may be as subtle as avoidance,or dramatic as physical aggression.COVID-19 has begun to cause social disruption by growing disease-related stigma and xenophobia against some cultural,national,racial or religious groups worldwide.1 People of East Asian origin and those with facial features like them,or those with a travel history to areas affected by the outbreak,are especially being subjected to xenophobia in personal contact and online threats.COVID-19 has arisen as an unknown and newly emerged highly contagious infection that has spread rapidly across the globe and is associated with high mortality,leading to fear of encountering those infected.2 Leaders across the world have taken strict measures such as lockdowns and shutdown of various vital services that have caused chaos in people’s lives and increased concerns about the disease.3 Box 1 lists the factors leading to stigmatisation towards those infected with COVID-19.

Dealing With Fakes

Imagine my surprise on buying a copy of Pink Floyd's album The Wall when I entered China six weeks ago, to find that the song name Comfortably Numb had somehow been translated into Come Partably Numb. And my amusement turned to despair once I discovered that only one of the two discs actually worked. Twelve yuan not so well spent. This was my introduction to the cheap but dubious world of China's CD pirates. Since arriving here, the problem of ille-

During that time, he earned a living through hard work while continuing to study. But he also received a court ruling requiring him to repay the debts he incurred in obtaining his bache-

Controversial protamine in dealing with acute cardiac tamponade during radiofrequency ablation

To the Editor:During radiofrequency catheter ablation(RFCA),acute cardiac tamponade is a common but life-threatening occurrence in which rapid blood accumulation in the pericardium cavity compresses the heart and causes the systemic circulation to deteriorate.Emergency percutaneous pericardiocentesis and immediate autologous blood transfusion are necessary.The administration of protamine for incessant bleeding is controversial,for pericardial blood clots may form spontaneously despite the neutralizing effects of heparin and may even necessitate thoracotomy.Our aim is to discuss the necessity and optimum time of protamine administration and to explore the means to prevent blood clot formation.

DEALING WITH HERNIAS What you need to know

Hernias can be caused by a number of different factors:any thing from lifting too much weight to having poor nutrition.When a hernia develops,it's important to know what you're dealing with any how to seek treatment.

Doing Business with China,the Entrepreneurial Way

The momentum of current economic engagement between China and Europe highlights the need for more cooperation,rather than the risk underscored by geopolitical rhetorics.AS entrepreneurs,traders,investors,and governments discuss economic resilience,competitiveness,and real and potential geopolitical crises,it is more than clear that the entrepreneurial spirit should take precedence when it comes to dealing with China.With the global pandemic behind us,the entrepreneurial spirit should show the path since it is connected to reality,and not speculations.

Chinese expert consensus on the clinical application of drugcoated balloon(2^(nd) Edition)

Percutaneous coronary interventions have progressed through the era of plain balloon dilation, bare-metal stent insertion to drug-eluting stent treatment, which has significantly reduced the acute occlusion and restenosis rates of target vessels and improved patient prognosis, making drug-eluting stents the mainstream interventional treatment for coronary artery disease. In recent years, drug-coated balloons(DCBs) have become a new treatment strategy for coronary artery disease, and the drugs used in the coating and the coating technology have progressed in the past years. Without permanent implant, a DCB delivers antiproliferative drugs rapidly and uniformly into the vessel wall via the excipient during a single balloon dilation. Many evidence suggests that DCB angioplasty is an effective measure for dealing with in-stent restenosis and de novo lesions in small coronary vessels.As more clinical studies are published, new evidence is emerging for the use of DCB angioplasty in a wide range of coronary diseases, and the indications are expanding internationally. Based on the latest research from China and elsewhere, the Expert Writing Committee of the Chinese Expert Consensus on Clinical Applications of Drug-Coated Balloon has updated the previous DCB consensus after evidence-based discussions and meetings in terms of adequate preparation of in-stent restenosis lesions, expansion of the indications for coronary de novo lesions, and precise guidance of DCB treatment by intravascular imaging and functional evaluation.

Cross-cultural Communication： Culture Shock and How to Deal with It

Willing or not, people must first encounter culture shock when they migrate from a familiar cultural background to a strange one. This thesis analyzes what causes culture shock and puts forward some suggestions to deal with it. Those who are about to go into a new culture environment may have some mental preparation.

Fish-on-Chips:unveiling neural processing of chemicals in small animals through precise fluidic control

Precise chemical cue presentation alongside advanced brainwide imaging techniques is important to the study of chemosensory processing in animals.Nevertheless,the dynamic nature of chemical-carrying media,such as water or air,poses a significant challenge for delivering highly-controlled chemical flow to an animal subject.Moreover,contact-based cue manipulation and delivery easily shift the position of the animal subject,which is often undesirable for high-quality brain imaging.Additionally,more advanced interfacing tools that align with the diverse range of body part sizes of an animal,ranging from micrometer-scale neurons to meter-long limbs,are much needed.This is particularly crucial when dealing with dimensions that are beyond the reach of conventional experimental tools.

Topology optimization of 3D shell structures with porous infill

This paper presents a 3D topology optimization approach for designing shell structures with a porous or void interior. It is shown that the resulting structures are significantly more robust towards load perturbations than completely solid structures optimized under the same conditions. The study indicates that the potential benefit of using porous structures is higher for lower total volume fractions.Compared to earlier work dealing with 2D topology optimization, we found several new effects in 3D problems. Most notably, the opportunity for designing closed shells significantly improves the performance of porous structures due to the sandwich effect. Furthermore, the paper introduces improved filter boundary conditions to ensure a completely uniform coating thickness at the design domain boundary.

Joint Dynamic Clustering and User Scheduling for Downlink Cloud Radio Access Network with Limited Feedback

In limited feedback-based CloudRAN(C-RAN) systems,the inter-cluster and intra-cluster interference together with the quantification error can seriously deteriorates the system spectral efficiency.We,in this paper,propose an efficient three-phase framework and corresponding algorithms for dealing with this problem.Firstly,a greedy scheduling algorithm based on the lower bound of the ergodic rate is performed for generating an elementary cluster in the first phase.And then the elementary cluster is divided into many small clusters according to the following proposed algorithms based on the short term instantaneous information in the second phase.In the end,based on the limited feedback two zero-forcing(ZF) precoding strategies are adopted for reducing the intra-cluster interference in the third phase.The provided Monte Carlo simulations show the effectiveness of our proposed algorithms in the respect of system spectral efficiency and average user rate.
