Natural biomaterials have benefited the human civilisation for millennia. However, in recent
years, designing of natural materials for a wide range of applications have become a focus …

Background The endoscopic radiofrequency procedure (Stretta) has been used for more
than a decade to treat patients with gastroesophageal reflux disease (GERD). However, the …

Cardiovascular diseases (CVD) constitute a major fraction of the current major global
diseases and lead to about 30% of the deaths, ie, 17.9 million deaths per year. CVD include …

Let G be a connected k-regular graph of order n. We find a best upper bound (in terms of k)
on the third largest eigenvalue that is sufficient to guarantee that G has a perfect matching …

Inkjet-printed enzyme-powered silk-based micro-rockets are able to undergo autonomous
motion in a vast variety of fluidic environments including complex media such as human serum…

Let λ 1 be the greatest eigenvalue and λ n the least eigenvalue of the adjacency matrix of a
connected graph G with n vertices, m edges and diameter D. We prove that if G is nonregular…

The lack of efficient and cost-effective methods for gene delivery has significantly hindered
the applications of gene therapy. In this paper, a simple one step and cost effective salting-out …

We find lower bounds on the difference between the spectral radius λ 1 and the average
degree 2en of an irregular graph G of order n and size e. In particular, we show that, if n⩾4, …

We study the minimum number of complete bipartite subgraphs needed to cover and partition
the edges of a k-regular bigraph on 2n vertices. Bounds are determined on the minima of …

Background: Both genetic and environmental factors are known to affect body mass index (BMI),
but detailed understanding of how their effects differ during childhood and adolescence …
