  • We prove that the diffusion coefficient for the two dimensional asymmetric simple exclusion process with nearest-neighbor-jumps diverges as (log t)2/3 to the leading order. The method applies to nearest and non-nearest neighbor asymmetric simple exclusion processes. 1. Introduction The asymmetric simple exclusion process is a Markov process on {0, 1}Z with asymmetric jump rates. There is at most one particle allowed per site and thus the word exclusion. The particle at a site x waits for an exponential time and then jumps to y with rate p(x − y) provided that the site is not occupied.

  • Size-exclusion chromatography (SEC) separates polymer molecules and biomolecules based on differences in their molecular size. The separation process in simplified form is based on the ability of sample molecules to penetrate inside the pores of packing material and is dependent on the relative size of analyte molecules and the respective pore size of the absorbent. The process also relies on the absence of any interactions with the packing material surface. Two types of SEC are usually distinguished: 1.

  • This potentially unique work offers various approaches on the implementation of nanowires. As it is widely known, nanotechnology presents the control of matter at the nanoscale and nanodimensions within few nanometers, whereas this exclusive phenomenon enables us to determine novel applications. Nanowire technology has considerably improved and developed many technologies and industry sectors in the field of IT, communications, computer technology, medicine devices, sensors applications and many others....

  • THE PRESIDENT OF LOCKHEED AIRCRAFT CORPORATION and Vice President Lyndon Johnson agreed to end Lockheed’s workforce segregation on May 25, 1961. Looking back, this contract, which was announced with great fanfare at the White House, signified far more than the public acknowledgment of systematic racial segregation in employment. It illustrated the leading role that prominent corporations were beginning to embrace by hiring and promoting the widest range of workers in this country.

  • Promoting equity and active citizenship: IPTS research results indicate that social media approaches to learning can mitigate existing inequalities and can be employed to successfully re-engage individuals who are at risk of exclusion from the knowledge society. Learning 2.0 strategies can effectively increase the accessibility and availability of learning opportunities for the hard to reach, and can significantly improve motivation and engagement in learning.

  • Investment banks have strong capital adequacy, in particular with respect to their hedge credit fund exposures – some estimates of which are provided below. Ironically, the fastest growing area of new financial products that utilise highly-complex derivative products exclusively lies mostly within the regulated sector. This is the market for “structured products” that are produced by investment banks and sold to retail, private bank and institutional clients.

  • The verifiability requirement prevents the full capitalization of future cash flow effects in earnings. When future net cash inflows are highly probable from an outlay, but their magnitude is not verifiable, the accrual process generally excludes the outlay from current earnings and capitalizes the cost as an asset (e.g., cash outlays for the purchase of inventory or plant). The effect of the exclusion of future cash inflows and their associated current outlays from earnings on the time series properties of earnings is 'a priori' unclear.

  • Finally certain destinations are branded unique-exotic-exclusive as they are regarded to offer a unique and precious experience. As a result, these destinations are promoted as “one-in-a-life- time” experience and they are promoted premium prices. Examples include Bhutan, Mauritius, and Seychelles. In some destinations, there are several mechanisms controlling the number of visitors, often through managing their transportation and accommodating capacity or immigration procedures and visa allowances.

  • Bacterial phytochromes (Bphs) are ancestors of the well characterized plant photoreceptors. Whereas plant phyto-chromes perform their photoisomerization exclusively via a covalently bound bilin chromophore, Bphs are variable in their chromophore selection. This is demonstrated in the cyanobacterium CalothrixPCC7601 that expresses two Bphs, CphA and CphB. CphA binds phycocyanobilin (PCB) covalently, whereas CphB, lacking the covalently binding cysteine of the plant phytochromes, carries biliver-din IXa (BV) as the chromophore....

  • We present a system for the real-time generation of car navigation instructions with landmarks. Our system relies exclusively on freely available map data from OpenStreetMap, organizes its output to fit into the available time until the next driving maneuver, and reacts in real time to driving errors. We show that female users spend significantly less time looking away from the road when using our system compared to a baseline system.

  • In this project, traffic simulation according to the cellular automaton of the Nagel-Schreckenberg model (1992) with different boundary conditions. The sudden occurrence of traffic jams is successfully realised as well as boundary induced phases and phase transitions are observed in the Asymmetric Simple Exclusion Process. The extension to the Velocity Dependent Randomization model leads to metastabile high flow states and hysteresis of the flow. The impact of speed limits on the probability of the formation of traffic jams is investigated.

  • Although the problem of querying a database in natural language has been studied extensively, there has been relatively little work on processing database updates expressed in natural language. To interpret update requests, several linguistic issues must be addressod that do not typically pose difficulties when dealing exclusively with queries.
