We construct an efficient identity based encryption system based on the standard learning with errors (LWE) problem. Our security proof holds in the standard model. The key step in the construction is a family of lattices for which there are two distinct trapdoors for finding short vectors. One trapdoor enables the real system to generate short vectors in all lattices in the family. The other t...

Figure 1: We present a view-based convolutional network that produces local, point-based shape descriptors. The network is trained such that geometrically and semantically similar points across different 3D shapes are embedded close to each other in descriptor space (left). Our produced descriptors are quite generic — they can be used in a variety of shape analysis applications, including dense...

Citation: Makris S (2015) Commentary: Viewing photos and reading nouns of natural graspable objects similarly modulate motor responses. Marino et al. (2014) in their paper (Frontiers in Human Neuroscience) have tried to investigate how the semantic processing of graspable objects involves an activation of the motor cortex in line with the affordance hypothesis originally proposed by Gibson (197...

In the second half of 20th century, ecological theory perception presented a new concept according to which it is not one-sided process within perceiver, in form representation and interpretation sensory data obtained from environment, but direct continuous interaction between percipient environment. Opposing almost intuitive acceptance numerous dualities based on traditionally accepted separat...

This paper reports an empirical study comparing the roles of representations in supporting face to face versus distance collaborative learning. Findings indicate that while face to face collaborators primarily use knowledge representations to summarize verbal reasoning, distributed collaborators also use knowledge representations to propose ideas before they are discussed, particularly ideas su...

Online review has become an important repository for consumers to make online buying decisions. However, writing online reviews is a voluntary behavior lacking guidelines and it is hard to guarantee the review quality generated. How to improve online review quality has become a challenge to online retailers and review aggregators. In this study, we explore the design of review writing interface...

Server-aided revocable identity-based encryption (SR-IBE), recently proposed by Qin et al. at ESORICS 2015, offers significant advantages over previous user revocation mechanisms in the scope of IBE. In this new system model, almost all the workloads on users are delegated to an untrusted server, and users can compute decryption keys at any time period without having to communicate with either ...

language learners tend to use their mother tongue while learning a second language conducted in error analysis framework, this study was aimed at investigating the persian syntactic errors in pieces of writing of a group of talysh-speaking students in north-and south-anbaran villages in gilan. the participants were third, fourth, and fifth grade elementary school students. the reasons and origi...

General value functions (GVFs) in the reinforcement learning (RL) literature are long-term predictive summaries of outcomes agents following specific policies environment. Affordances as perceived action possibilities with valence may be cast into predicted policy-relative goodness and modeled GVFs. A systematic explication this connection shows that GVFs especially their deep-learning embodime...

Abstract Drawing from the social capital framework and socioemotional selectivity theory, this study examines how individuals’ future time perspective (FTP) alters their processes, which further influences well-being. A two-wave survey was conducted across WeChat users possessing different FTPs. The findings showed that bonding bridging accumulation were attributed to differential affordances, ...
