NOD/LtSz-prkdc(scid)/prkdc(scid) (non-obese diabetic-severe combine immunodeficiency; NOD-scid) mice grafted with human peripheral blood lymphoid cells have been used as an in vivo humanized mouse model in various studies. However, cytotoxic human T cells are induced in this model during immune responses, which gives misleading results. To assist in(More)
The chemokine stromal-cell derived factor-1 (SDF-1) controls maturation, trafficking, and homing of certain subsets, lymphoid cells including immunogenic B and T cells, as a ligand of the CXCR4 chemokine receptor. Insulin-dependent diabetes mellitus (IDDM) and Sjögren's syndrome (SS), both highly regulated autoimmune diseases, develop spontaneously in(More)
E2f1 is an important regulator of T cell proliferation, differentiation, and apoptosis that controls the transcription of a group of genes that are normally regulated at the G1 to S phase transition in the cell cycle. Insulin-dependent diabetes mellitus (IDDM) and Sjogren's syndrome (SS) are highly regulated autoimmune diseases that develop spontaneously in(More)
Wireless sensor networks (WSN) are resource-constrained self-organizing networks that are often deployed in hostile and inaccessible environments in order to collect data. The reliability of WSN is affected by faults that may occur due to various reasons such as malfunctioning hardware, software glitches, dislocation, or environmental hazards. Appropriate(More)
Wireless sensor network (WSN) has enormous applications in many places for monitoring the environments of importance. Sensor nodes are capable of sensing, computing, and communicating. These sensor nodes are energy constraint and operated by batteries. Since energy consumption is an important issue of WSN, there have been many energy-efficient protocols(More)
Wireless sensor network (WSN) is highly used in many fields. The network consists of tiny lightweight sensor nodes and is largely used to scan or detect or monitor environments. Since these sensor nodes are tiny and lightweight, they put some limitations on resources such as usage of power, processing given task, radio frequency range. These limitations(More)
Presently, there are not many literatures on the characterization of reputation and trust in wireless sensor networks (WSNs) which can be referenced by scientists, researchers and students. Although some research documents include information on reputation and trust, characterization of these features are not adequately covered. In this paper, reputation(More)
Wireless sensor networks (WSNs) are resource-constrained self-organizing networks that are often deployed in hostile and inaccessible environments in order to collect data. Benign system faults such as malfunctioning hardware, software glitches, and environmental hazards may impact overall system reliability but can often be mitigated by appropriate fault(More)
