In keeping with the traditional emphasis on safety, nuclear technologists were prompted by the Chernobyl accident (1986), to consider the consequences of accidents Beyond the Design Basis Accident (BDBA) scenarios, despite the fact, that the probability of such an occurrence was considered extremely low. These consequences, though highly unlikely, necessitate additional measures to protect the ...

We look at the problem of signal transduction by extracellular agonist binding to a receptor protein at the membrane (sensor) via binding of G-proteins (effectors) to a highly integrative target molecule, such as the second messenger cAMP (target). We explore the effects of binding times, effector assignment and effector pool size on the shape of the output signal under different input scenario...

We consider the problem of constructing codes that can correct δ deletions occurring in an arbitrary binary string of length n bits. Varshamov-Tenengolts (VT) codes can correct all possible single deletions (δ = 1) with an asymptotically optimal redundancy. Finding similar codes for δ ≥ 2 deletions is an open problem. We propose a new family of codes, that we call Guess & Check (GC) codes, that...

At least 4 weeks after inoculation. they received either allogeneic (DA or LEW) or syngeneic corneel grafts end were exemined for stgns of recurrent HSV disease for up lo 30 days. m All allografts wara rejactad.

Binary Exponential Backoff (BEB) is the De-facto mechanism for contention control in IEEE 802.11 Wireless LAN. The exponential growth of Contention Window (CW) in all BackOff (BO) stages and randomness in BO selection causes unnecessary waiting time, high collision rate and unfairness in accessing the channel among the nodes. To overcome these anomalies, this paper proposes Hashing Based Distri...

Abstract Long-term mitigation scenarios developed by integrated assessment models underpin major aspects of recent IPCC reports and have been critical to identify the system transformations that are required meet stringent climate goals. However, they criticized for proposing pathways may prove challenging implement in real world failing capture social institutional challenges transition. There...
