background: apical leakage assessment is a way to compare the effi ciency of a fi lling material to seal the apical region of the tooth. many microleakage testing techniques have been introduced through the years, but there has been no agreement as to which technique gives the most accurate results. the aim of this study was to compare the accuracy of fl uid fi ltration and bacterial leakage te...

fibrillation is a hazardous phenomenon in cardiac muscle and so any new work towards the understanding of this process is important to the development of new methods in diagnosis and therapy. in this work we have used surface and intra cardiac ecgs of patients with chronic atrial fibrillation (af). by means of the blind source separation (bss) algorithm, which is a well-known method in signal p...

In this work, we show that strong leakage resilience for cryptosystems with advanced functionalitiescan be obtained quite naturally within the methodology of dual system encryption, recently introducedby Waters. We demonstrate this concretely by providing fully secure IBE, HIBE, and ABE systems whichare resilient to bounded leakage from each of many secret keys per user, as well as ...

A new generalised approach for multiple correlated sources over a wiretap network is investigated. A basic model consisting of two correlated sources where each produce a component of the common information is initially investigated. There are several cases that consider wiretapped syndromes on the transmission links and based on these cases a new quantity, the information leakage at the source...

Innovation is becoming more and more important in modern society. There are a lot of researches on different kinds of innovation but marketing innovation is one kind of innovation that has not been studied frequently before. Marketing innovation is defined as a new way in which companies can market themselves to potential or existing customers. The study shows some key elements for marketing in...

Consider the problem of information disclosure for a planner who faces two agents interacting in a state-dependent multi-action prisoners’dilemma. We …nd conditions under which the planner can make use of his superior information by disclosing some of it to the agents, and conditions under which such information leakage is not possible. Although the problem is entirely symmetric, the planner’s ...

The goal of leakage-resilient cryptography is to construct cryptographic algorithms that are secure even if the adversary obtains side-channel information from the real world implementation of these algorithms. Most of the prior works on leakage-resilient cryptography consider leakage models where the adversary has access to the leakage oracle before the challenge-ciphertext is generated (befor...

nicotine-based ionic liquid has been used as a green catalyst for pyridine-catalyzed huisgen reaction. it promoted addition of dimethylacetylenedicarboxylate to aldehydes or n-tosyl imines leading to efficient synthesis of 2-benzoylfumarates and 1-azadienes respectively under pyridine free odorless ionic liquid conditions. the improved results were obtained in terms of enhanced yields, with min...

There are three major sources of leakage current today, namely the sub-threshold leakage, gate leakage and the reverse biased junction band-to-band-tunneling leakage. These currents depend on the logic state of a CMOS circuit as determined by input pattern. Consequently, there exists a pattern that will produce the highest leakage current. Previously, researchers have investigated the problem o...
