In this paper, the individual secrecy of two-way wiretap channel is investigated, where two legitimate users’ messages are separately guaranteed secure against an external eavesdropper. For one thing, in some communication scenarios, the joint secrecy is impossible to achieve both positive secrecy rates of two users. For another, the individual secrecy satisfies the secrecy demand of many pract...

An algorithm is proposed in this paper that finds exact exclusive-or sum-of-products of an arbitrary function, provided the number of product terms is less than eight. If the number of product terms in the minimal expression is more than seven, then the algorithm detects it and heuristically returns near-optimal expressions. The algorithm is time and space efficient even for functions with many...

The conference Photon 2009 on the structure and the interactions of the photon included sessions on photon-photon collisions and a future high-energy photon linear collider. This summary of theoretical contributions to the conference therefore has two parts. I will discuss the physics potential of photon colliders with an emphasis on the study of electroweak physics and the search for physics b...

thirty-two exclusive and twenty-seven non-exclusively breast-fed infants were followed-up from birth to 4 months of age in a maternity hospital, with a rooming-in program. face to face bf education was given to mothers in two groups after delivery and also during 4 months post-partum. body weight (wt ), length (l) and head circumference (hc) of the infants were measured at monthly intervals, an...

background: necrotizing enterocolitis (nec) is one of the most destructive diseases associated with conditions of neonatal prematurity. supplementation with enteral prebiotics may reduce the incidence of nec, especially in infants who fed exclusively with breast-milk. therefore, we compared the efficacy and safety of enteral supplementation of a prebiotic mixture (short chain galacto-oligosacch...

promote and support breastfeeding is an essential element for the health and development of infants so that, it introduced as most cost-effective intervention to reduce infant mortality in developing countries (1). breastfeeding has an important role to ensure food security for maintain a healthy and productive life for a large proportion of babies in the world, in addition, it is associated wi...

This paper presents a new operation (Exorlink) and an algorithm to minimize Exclusive-OR Sum-of-Products expressions (ESOPs) for multiple valued input, two valued output, incompletely speciied functions. Exorlink is a more powerful operation than the existing ones for this problem. Evaluation on benchmark functions is given and it proves the superiority of the program to those known from the li...

The Sensitivity Conjecture and the Log-rank Conjecture are among the most important and challenging problems in concrete complexity. Incidentally, the Sensitivity Conjecture is known to hold for monotone functions, and so is the Log-rank Conjecture for f(x∧y) and f(x⊕y) with monotone functions f , where ∧ and ⊕ are bit-wise AND and XOR, respectively. In this paper, we extend these results to fu...
