Domain name system (DNS) resolution service is usually provisioned by multiple authoritative servers for performance and robustness. Estimating the query load distribution among multiple authoritative servers is one of the key issues arising with DNS server load balancing and optimization. We propose an analytical model of Round-Trip-Time (RTT)-sensitive server selections consisting of cache se...

Dependency networks (DNs) have been receiving more attention recently because their structures and parameters can be easily learned from data. The full conditional distributions (FCDs) are known conditions of DNs. Gibbs sampling is currently the most popular inference method on DNs. However, sampling methods converge slowly and it can be hard to diagnose their convergence. In this article, we i...

Objectives: Dynamic Neuromuscular Stabilization (DNS) approach evaluates and activates the spinal stabilizers to optimize the performance of posture and respiratory system. This study investigated the effects of DNS breathing exercises on upper and lower chest wall mobility (UCM and LCM), trunk extensor endurance, and thoracic kyphosis in a group of sedentary students with poor posture. Method...

Globally unique domain names and IP addresses that are provided in real time by the DNS (Domain Name System) represent the fundamental signposts for navigating the Internet and for locating remote hosts. It is therefore paradoxical that the traditional method for secure identification of remote hosts is not directly based on DNS, but on the browser PKI which is external to the trust structure o...

In conventional egress network access control (NAC) based on access control lists (ACLs), modifying the ACLs is a heavy task for administrators. To enable configuration without a large amount of administrators’ effort, we introduce capabilities to egress NAC. In our method, a user can transfer his/her access rights (capabilities) to other persons without asking administrators. To realize our me...

The “equation-free” (EF) method is based on a procedure, which is often used in complex, multi-scale problems, given an initial macroscopic variable, by lifting, evolve in Direct Numerical Simulations (DNS), restriction, and projective integration. In this paper, we apply the Equation-free method to the reduced modeling of a large-scale upper ocean circulation in the tropic Pacific domain. We c...

A method was developed for simultaneous qualitative and quantitative analysis of five metabolites of nitrofuran antibiotics, including 3-amino-2-oxazolidinone (AOZ), 5-morpholino-methyl-3-amino-2-oxazolidinone ( AMOZ ), semicarbazide ( SEM ), 1-aminohydantoin (AHD) and 3, 5-dinitrosalicylic acid hydrazide (DNSH) in aquatic products by liquid chromatography-tandem mass spectrometry (LC-MS/MS). T...

This paper explores taking a passive approach to covert communication over DNS. By exploiting the slack space that can be created in DNS packets, data may be inserted into packets without affecting the operation of DNS resolvers and security tools. Several locations in the packet exist that allow additional data to be inserted into the network traffic without being noticed by applications befor...
