Since the advent of software defined networks ({SDN}), there have been many attempts to outsource complex and costly local network functionality, i.e. middlebox, cloud in same way as outsourcing computation storage. The privacy issues, however, may thwart enterprises' willingness adopt this innovation since underlying configurations these middleboxes leak crucial confidential information which can be utilized by attackers. To address new problem, we use firewall an sample functionality...

Online behavioral advertising (OBA) has become one of the most successful models on Internet. Nevertheless, all existing OBA systems are broker-centric in billing phase, which means it is broker who exclusively determines advertisers' expenses and publishers' revenues. Consequently, a malicious may cheat their tallying ad clicks to overcharge advertisers or underpay publishers. Furthermore, as cannot justify bills, deny actual ask for refunds, publishers claim non-existing demand extra...

Retrieving an object from cluttered spaces such as cupboards, refrigerators, or bins requires tracking objects with limited no visual sensing. In these scenarios, contact feedback is necessary to estimate the pose of objects, yet are movable while their shapes and number may be unknown, making association contacts extremely difficult. While previous work has focused on multi-target tracking, assumptions therein prohibit using prior methods given only contact-sensing modality. Instead, this...

We propose an approach to online model adaptation and control in the challenging case of hybrid discontinuous dynamics where actions may lead difficult-to-escape "trap" states, under a given controller. first learn for system without traps from randomly collected training set (since we do not know what will be encountered online). These "nominal" allow us perform tasks scenarios matches data, but when unexpected arise execution, must find way adapt our strategy continue attempting task. Our...

RNA-chromatin interactions play crucial roles in gene regulation and genome organization, but the interaction landscape remains poorly understood. In this study, we conducted an in-depth analysis of a previously published dataset on RNase-treated situ mapping RNA–genome interactome human embryonic stem cells. This globally profiles RNase-insensitive interactions. Our revealed that RNase treatment selectively preserved long-range while removing promiscuous resulting from local diffusion...

Intuitively, extrapolating an object’s trajectory should facilitate visual tracking. This intuition has motivated several investigations into whether humans extrapolate when tracking multiple objects. Surprisingly, they appear not to, largely ignoring motion, and implementing a low-level, spatial memory function instead. Why do to if extrapolation is beneficial? We address this question by interrogating its underlying assumption: that beneficial in the first place. Recent advances have...
