developmental dysplasia of the hip (ddh) is one of the most widely discussed abnormalities in neonates. the advantages of sonographic examination are well known, but its main disadvantage is that it might lead to over diagnosis, which might cause over treatment. variations in the incidence of developmental dysplasia of the hip are well known. during six months study since september 2006 all 130...

Neural circuits, structural and functional connections between neurons, are fundamental to nervous system function. Detailed understanding of the “built-in” connectivity is essential for insight how a neural system works under normal and abnormal conditions. For many parts of the mammalian CNS, understanding of basic neural wiring remains limited. Despite its importance for somatosensory functi...

We introduce implicit zero-knowledge arguments (iZK) and simulation-sound variants thereof (SSiZK); these are lightweight alternatives to zero-knowledge arguments for enforcing semi-honest behavior. Our main technical contribution is a construction of efficient two-flow iZK and SSiZK protocols for a large class of languages under the (plain) DDH assumption in cyclic groups in the common referen...

An important problem in cryptography is the so called Decision Diffie-Hellman problem (henceforth abbreviated DDH). The problem is to distinguish triples of the form (g, g, g) from arbitrary triples from a cyclic group G = 〈g〉. It turns out that for (cyclic subgroups of) the group of m-torsion points on an elliptic curve over a finite field, the DDH problem admits an efficient solution if there...

Verifiable random functions (VRF) and selectively-convertible undeniable signature (SCUS) schemes were proposed independently in the literature. In this paper, we observe that they are tightly related. This directly yields several deterministic SCUS schemes based on existing VRF constructions. In addition, we create a new probabilistic SCUS scheme, which is very compact. The confirmation and di...

background: the prevalence of neglected developmental dysplasia of the hip (ddh) has been decreasing. nowadays, the disease is rarely seen in walking age children. the purpose of this study is to assess the results of simultaneous osteotomy of femur and pelvic bones in such children. method: we performed a retrospective study on 30 children aged 3.8±0.9 (range: 1.5-7) years old, with ddh who un...

Telemedicine holds important place and has wider use in health care practice and improvement of health organization, above all providing the opportunity for standard and innovative procedures to combine. Tremendous increase in Internet bandwidth enabled a true revolution in image transmission and enabled easy remote viewing of the static images. However, transmission of real time video streams ...

This paper proposes a simple threshold Public-Key Cryptosystem (PKC) which is secure against adaptive chosen ciphertext attack, under the Decisional Diffie-Hellman (DDH) intractability assump-
