A logical link composed of multiple physical links is in extensive use in today’s Internet and its use is growing due to good scalability, reliability and cost-effectiveness. When IP packets are distributed over such physical links, load unbalancing and packet reordering may occur. Since packet reordering degrades TCP performance, a good traffic distribution method must reduce the amount of reo...

Random exponential marking (REM) is an attractive adaptive queue management algorithm. It uses the quantity known as ‘price’ to measure the congestion in a network. REM can achieve high utilisation, small queue length, and low buffer overflow probability. Many works have used control theory to provide the stable condition of REM without considering the feedback delay. Recently, sufficient condi...

The purpose of this study was to evaluate the microtensile bond strength (µTBS) of a newly developed resin cement, ECD-89 (ECD, Tokuyama Dental, Tokyo, Japan) to dentin and to observe the interfacial micromorphology by comparing with two commercial resin cements, Multilink Automix (MA, Ivoclar Vivadent AG, Schaan, Liechtenstein) and Panavia F2.0 (PF, Kuraray Noritake Dental, Tokyo, Japan). Flat...

Zinc finger proteins acquire DNA-binding ability by Zn (II) complexation. In the zinc finger domain of the Cys2His2 type, each finger is approximately 30 amino acid residues long and consists of a simple ββα–fold stabilized by chelation of a zinc ion with the conserved Cys2His2 residues. A zinc finger motif of Cys2His2 offers an attractive framework for the design of a novel DNA-binding protein...

DESCRIPTION A 14-year-old adolescent boy presented 3 days after lacerating his hand with a knife. He complained of inability to flex his little finger and had decreased sensation on the ulnar aspect of this digit.

This study aimed to continue our characterization of finger strength and multi-finger interactions across the lifespan to include those in their 60s and older. Building on our previous study of children, we examined young and elderly adults during isometric finger flexion and extension tasks. Sixteen young and 16 elderly, gender-matched participants produced maximum force using either a single ...

In a majority of studies on grasp, only normal forces were measured and only when a zero torque was exerted on a hand-held object. This study concerns finger force vectors during the torque production tasks. Subjects (n=8) stabilized a handle with an attachment that allowed for change of external torque from -1.5 to 1.5 Nm. Forces and moments exerted by the digit tips on the object were recorde...

Perception during action is optimized by sensory predictions about the likely consequences of our movements. Influential theories in social cognition propose that we use the same predictions during interaction, supporting perception of similar reactions in our social partners. However, while our own action outcomes typically occur at short, predictable delays after movement execution, the react...

The perception of tactile stimuli presented on a moving hand is systematically suppressed. Such suppression has been attributed to the limited capacity of the brain to process task-irrelevant sensory information. Here, we examined whether humans do not only suppress movement-irrelevant but also enhance in parallel movement-relevant tactile signals when performing a goal-directed reaching moveme...
