The sequential interactions between T lymphocyte subsets have been well characterized in several systems of antigen-specific immune suppression (1-2). The immune response to the hapten 4-hydroxy-3-nitrophenyl acetyl (NP) a has become one of the most extensively characterized of these model systems (3-6). Previous studies from our laboratory have revealed that in this suppressor network system, ...

Temperature-sensitive folding mutations (tsf) of the thermostable P22 tailspike protein prevent the mutant polypeptide chain from reaching the native state at the higher end of the temperature range of bacterial growth (37-42 degrees C). At lower temperatures the mutant polypeptide chains fold and associate into native proteins. The melting temperatures of the purified native forms of seven dif...

Time series forecasting (TSF) have been widely used in many application areas such as science, engineering, and finance. Usually the characteristics of phenomenon generating a series are unknown and the information available for forecasting is limited to the past values of the series. It is, therefore, important to use an appropriate number of past values, termed lag, for forecasting. Although ...

The tautomerase superfamily (TSF) consists of more than 11,000 nonredundant sequences present throughout the biosphere. Characterized members have attracted much attention because of the unusual and key catalytic role of an N-terminal proline. These few characterized members catalyze a diverse range of chemical reactions, but the full scale of their chemical capabilities and biological function...

Leaf Area Index (LAI) is an important biophysical variable for characterizing the land surface vegetation. Global LAI product has been routinely produced from the MODerate resolution Imaging Spectroradiometer (MODIS) aboard the Terra and Aqua satellite platforms. However, the MODIS standard LAI product is not continuous both spatially and temporally. To fill the gaps and improve the quality, we...

OBJECTIVE Time-related changes and comparisons for mid-upper arm circumference (MUAC), triceps skinfold thickness (TSF), arm fat area (AFA) are lacking for Turkish children and adolescents. To determine the arm anthropometry indices (MUAC, TSF, AFA) in children and adolescents and to also assess the changes in these indices over a 3-year time period. METHODS The data of the Anthropometry of T...

presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. although the available fluoride concentration in iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. this study was done to assess the fluoride ion concentration and stability ...

The forecast of Internet traffic is an important issue that has received few attention from the computer networks field. By improving this task, efficient traffic engineering and anomaly detection tools can be created, resulting in economic gains from better resource management. This paper presents a Neural Network Ensemble (NNE) for the prediction of TCP/IP traffic using a Time Series Forecast...

A new principle for supplying volatile precursors to MOCVD gas-phase chemical deposition systems is proposed, based on a two-stage evaporation of an organic solution from soaked cotton thread, which passes sequentially through the zones solvent and precursors. The technological capabilities TSF-MOCVD (Thread-Solution Feed MOCVD) are demonstrated examples obtaining thin epitaxial films СеО2, h-L...
