Elastic mechanisms in the invertebrates are fantastically diverse, yet much of this diversity can be captured by examining just a few fundamental physical principles. Our goals for this commentary are threefold. First, we aim to synthesize and simplify the fundamental principles underlying elastic mechanisms and show how different configurations of basic building blocks can be used for differen...

We show fundamental properties of the Markov semigroup recently proposed MCMC algorithms based on Piecewise-deterministic processes (PDMPs) such as Bouncy Particle Sampler, Zig-Zag process or Randomized Hamiltonian Monte Carlo method. Under assumptions typically satisfied in settings, we prove that PDMPs are Feller and their generator admits space infinitely differentiable functions with compac...

Okra (Abelmoschus esculentus) and Sebestan (Cordia myxa) fruits were used as plant binders in the diets of Bunni (Barbus sharpeyi) . These beside a control diet without binder., compared with starch traditional binders.All included by 2% two replicates for each treatments. Feeding rate was 4% fish weight 70 days. The physical properties showed that has highest density while containing lowest fo...

Security is critical for wireless sensor networks. While several security mechanisms and protocols have been developed in the context of the Internet, many new challenges arise due to the characteristics of power-constrained wireless sensor networks. In this work, we focus on the Javaprogrammable SunSPOT device and elliptic curve cryptography (ECC). We present an analysis of run times and energ...

Using cloud storage servers to manage large amounts of data has gained increased interest due to their advantages (like availability and scalability). A major disadvantage of cloud storage providers, however, is their lack of security features. In this article we analyze a cloud storage setting where confidentiality of outsourced data is maintained by letting the client encrypt all data records...

Many web hosts are still vulnerable to one of the oldest attacks against RSA in TLS. We show that Bleichenbacher’s RSA vulnerability from 1998 is still very prevalent in the Internet and affects almost a third of the top 100 domains in the Alexa Top 1 Million list, among them Facebook and Paypal. We identified vulnerable products from at least eight different vendors and open source projects, a...

The Bouncy Particle sampler (BPS) and the Zig-Zag (ZZS) are continuous time, non-reversible Monte Carlo methods based on piecewise deterministic Markov processes. Experiments show that speed of convergence these samplers can be affected by shape target distribution, as for instance in case anisotropic targets. We propose an adaptive scheme iteratively learns all or part covariance matrix takes ...
