third-generation (3G) networks, conversational video-telephony services are becoming a key differentiator between new 3G offerings and existing 2G/2.5G services. Although it’s possible to have limited video-based services—such as a multimedia messaging service—that deliver pictures and video clips over 2.5G services, these are delay-insensitive applications that could run over a packet-based wi...

Repeaters have been an attractive solution for mobile operators to upgrade their wireless networks at low cost and to extend network coverage effectively. Since the first LTE commercial deployment in 2009, many mobile operators have launched LTE networks by upgrading their 3G and legacy networks. Because all 3G frequency bands are shared with the frequency bands for LTE deployment and 3G mobile...

CD19-targeting CAR T cells have shown potency in clinical trials targeting B cell leukemia. Although mainly second generation (2G) CARs carrying CD28 or 4-1BB have been investigated in patients, preclinical studies suggest that third generation (3G) CARs with both CD28 and 4-1BB have enhanced capacity. However, little is known about the intracellular signaling pathways downstream of CARs. In th...

A 3-gdd of type gu exists if and only if g and u have the same parity, 3 divides u and u ≤ 3g. Such a 3-gdd of type gu is equivalent to an edge decomposition of Kg,g,g,u,u into triangles. 2010 MSC: 05B05, 05B07, 05C70

Glycine, Alanine and Valine are taken as amino acids with an equal polar head and with thedifference in the length of hydrocarbon chains. The structural optimizations show the results of theisolated Glycine, Alanine and Valine in the gases phase, at the Hartree-Fock level by means ofSTO-3G,3-21G, 6-31G and 6-31+G basis sets. The calculations were performed for the ten (1-10)solvents using PCM m...

The third generation networks and services present opportunities to offer multimedia applications and services that meet end-to-end quality of service requirements. The key parts of the standards are already in place, and limited 3G services have already been turned on. While the evolution to 3G occurs, many operators will implement 2.5G interim solutions for a good period of time. In this arti...

This study aims to examine the relationship between perceived usefulness, perceived ease of use, perceived enjoyment, attitude and subscribers’ intention towards using 3G mobile services. Cross sectional data were collected through a survey and analysed by means of factor analysis, correlation and regression analysis. Out of 150 questionnaires only 100 were usable. Findings show that Perceived ...
