The regurgitant volume of TR might increase dynamically despite unchanged effective regurgitant orifice area, thus exaggerating TR severity on echocardiographic assessment. Meanwhile, functional TR from various chronic and acute cardiomyopathies may significantly reverse either by itself or after medical treatment. Thus, integrated analysis on both cardiac imaging and clinical data of functiona...

This issue’s Biomedicine Select highlights new insights into the role of mitochondria in disease. Several new studies implicate abnormal mitochondria in the destruction of neurons of the substantia nigra, the cause of Parkinson’s disease (PD). Meanwhile, an elegant computational approach has enabled identification of candidate genes for several mitochondrial diseases including the mitochondrial...

The joint sparse recovery problem is a generalization of the single measurement vector problem widely studied in compressed sensing. It aims to recover a set of jointly sparse vectors, i.e., those that have nonzero entries concentrated at a common location. Meanwhile lp-minimization subject to matrixes is widely used in a large number of algorithms designed for this problem, i.e., l2,p-minimiza...

163 Corrigendum to " Minimal KC-spaces are countably compact " T. Vidalis Unfortunately, there is a gap in the proof of Theorem 3.5 in [1]. However, an even stronger result than that in this theorem has been proved meanwhile by Bella and Costantini [2].

We introduce a central difference method and a quasi-reversibility method for solving a backward heat conduction problem (BHCP) numerically. For these two numerical methods, we give the stability analysis. Meanwhile, we investigate the roles of regularization parameters in these two methods. Numerical results show that our algorithm is effective. 2005 Elsevier Inc. All rights reserved.

Big pharma is increasingly looking to academia for new drug leads and technologies; meanwhile universities are being forced to look beyond the National Institutes of Health (NIH) for funding. This mutual attraction-out-of-necessity is helping to forge new bonds between industry and academia.

Non-standard backward heat conduction problem is ill-posed in the sense that the solution (if it exists) does not depend continuously on the data. In this paper, we propose a regularization strategy-quasi-reversibility method to analysis the stability of the problem. Meanwhile, we investigate the roles of regularization parameter in this method. Numerical result shows that our algorithm is effe...

The ATHENE modelling tool enables business people to create knowledge-intense process models without having to know the complexity of modelling ontologies. ATHENE is based on a three-level hierarchy of metameta, meta and object level. It allows business people to model business processes graphically meanwhile these processes are transformed internally into ontologies.

This paper presents a new approach to determining the effective refractive index of single living cell. By means of it, the refractive index of living cell can be automatically measured in real time without any extra treatments on the cell, meanwhile, offering low cost and high accuracy of disease diagnosis.

The recent work [YZZ] completes a general Gross–Zagier formula for Shimura curves. Meanwhile an arithmetic version of Gan–Gross–Prasad conjecture proposes a vast generalization to higher dimensional Shimura varieties. We will discuss the arithmetic fundamental lemma arising from the author’s approach using relative trace formulae to this conjecture.
