Oblivious RAM (ORAM) is a cryptographic primitive which obfuscates the access paŠerns to a storage thereby preventing privacy leakage. So far in the current literature, only ‘fully functional’ ORAMs are widely studied which can protect, at a cost of considerable performance penalty, against the strong adversaries who can monitor all read and write operations. However, recent research has shown ...

Nervous and neuroendocrine systems mediate environmental conditions to control a variety of life history traits. Our goal was to provide mechanistic insights as to how neurosecretory signals mediate division of labor in the honey bee (Apis mellifera). Worker division of labor is based on a process of behavioral maturation by individual bees, which involves performing in-hive tasks early in adul...

Critical to the proper maintenance of blood-brainbarrier (BBB) integrity are the endothelial tight junctions (TJs). Posttranslational modifications of essential endothelial TJ proteins, occludin and claudin-5, contribute and possibly disrupt BBB integrity. Our previous work has shown that Rho kinase (RhoK) activation mediates occludin and claudin-5 phosphorylation resulting in diminished barrie...

Mouth-to-mouth food exchange in eusocial insects (trophallaxis) contributes to the organization of complex social activities. In the case of honeybees, foragers returning from a nectar source transfer the food collected to receiver colony-mates through oral contact. Previous studies have shown that the speed of nectar transfer within each contact (unloading rate) increases when foragers return ...

A honeybee hive serves as an information centre in which communication among bees allows the colony to exploit the most profitable resources in a continuously changing environment. The best-studied communication behaviour in this context is the waggle dance performed by returning foragers, which encodes information about the distance and direction to the food source. It has been suggested that ...

Abstract Context To date, managing honey bees and wild within crop fields remains challenging. Landscape structure is often overlooked when studying the pollination contribution of bees. Increasing our understanding on how to predict bee visitation in crops crucial for sustainable management agroecosystems. Objectives With this study we investigated which landscape field-level variables determi...

We define the hive ring, which has a basis indexed by dominant weights for GLn(C), and structure constants given by counting hives [KT1] (or equivalently honeycombs, or Berenstein-Zelevinsky patterns [BZ1]). We use the octahedron rule from [RR, FZ, P, S] to prove bijectively that this “ring” is indeed associative. This, and the Pieri rule, give a self-contained proof that the hive ring is isomo...

The classic BDI model focuses on the internal functioning of a single-agent architecture. Neither shared beliefs nor spontaneous and indirect coordination via the environment are supported. We describe Hive-BDI, an extension of the Jason BDI-style language with shared beliefs implemented via the logic-based coordination language ReSpecT and with stigmergy obtained via digital pheromones. A case...

x We describe DIRECT-BP, a modiication to the DIRECT algorithm that attempts to perform a more balanced search about the best point found in each iteration. DIRECT ensures the division of one of the largest boxes in each iteration , which asymptotically guarantees convergence to a global optimum. We demonstrate that DIRECT can fail to eeectively perform local search about the best point found e...

We give a new black-box transformation from any semantically secure encryption scheme into a non-malleable one which has a better rate than the best previous work of Coretti et al. (TCC 2016-A). We achieve a better rate by departing from the “matrix encoding” methodology used by previous constructions, and working directly with a single codeword. We also use a Shamir secret-share packing techni...
