Access tohealthcare services using public transportation(PT-based healthcareaccessibility)is a crucial aspect in achieving healthcare equity as it affects individuals’ability to receive healthcare.Previous research h...
Integer factorization (IFP), also called prime factorization, is an important problem in number theory, cryptography, and quantum computation. Factoring large integers to attack the RSA cryptosystem is intractable for...

RSA cryptography is based on the difficulty of factoring large integers, which is an NP-hard(and hence intractable) problem for a classical computer. However, Shor's algorithm shows that its complexity is polynomial f...
Countries are seeking to diversify sources of revenue for Universal Health Coverage (UHC), and strategies vary among countries at different stages on the road to UHC. The study tends to document these trade-offs by fa...
This paper proposes three new attacks. In the first attack we consider the class of the public exponents satisfying an equation e X-N Y +(ap^r+ bq^r)Y = Z for suitably small positive integers a, b. Applying contin...
The intestinal microbiome is a reservoir of microbial antigens and activated immune cells. The aims of this review were to describe the role of the intestinal microbiome in generating innate and adaptive immune respon...

Let D=pq be the product of two distinct odd primes.Assuming the parity conjecture,we construct infinitely many r≥1 such that E2rD:y2=x3-2rDx has conjectural rank one and vp(x([k]Q))≠vq(x([k]Q))for any odd integer k,...

We propose a novel method to compute a cubic root of a cubic residue in Eisenstein ring. By applying our method, a new identity based signature scheme is proposed based on cubic residues. We formally prove that our sc...
