Consider a network of computers interconnected by point-to-point communication channels. Before generating network packets, each source in the network reserves a fraction of the packet rate of each output channel in the path to its destination. We define a family of scheduling protocols, called Universal Timestamp-Scheduling, to forward packets in this network such that all members of the proto...

Among the multiple roles assigned to calmodulin (CaM), controlling the surface expression of Kv7.2 channels by binding to two discontinuous sites is a unique property of this Ca(2+) binding protein. Mutations that interfere with CaM binding or the sequestering of CaM prevent this M-channel component from exiting the endoplasmic reticulum (ER), which reduces M-current density in hippocampal neur...

der folgende text, der unter der betreuung von herrn dr. touraj rahnema entstanden ist, erw?hnt zuerst kurz die bestimmenden züge der literarischen schule, die im europ?ischen kulturraum allgemein als romantik verstanden wird, will aber darüber hinaus die romantik als eine art lebenshaltung und kunstverst?ndnis begreifen, die unabh?ngig von einer bestimmten kunstperiode genauso auch in ?stliche...

The data of inelastic 16O+16O scattering to the lowest 2+ and 3 excited states of 16O have been measured at Elab = 250, 350, 480, 704 and 1120 MeV and analyzed consistently in the distorted wave Born approximation (DWBA), using the semimicroscopic optical potentials and inelastic form factors given by the folding model, to reveal possible refractive structure of the nuclear rainbow that was ide...

This paper provides simple lower bounds on the number of iterations which is required for successful message-passing decoding of some important families of graph-based code ensembles (including low-density parity-check codes and variations of repeat-accumulate codes). The transmission of the code ensembles is assumed to take place over a binary erasure channel, and the bounds refer to the asymp...

The correct approach to electron transport modeling in Hall thrusters is an open question in the field and is compounded by a lack of comparative studies on the relative influence of various proposed electron transport mechanisms in the thruster plume. Lacking an analytical model for transport, empirical coefficients are used in most models to reproduce major discharge parameters like the total...

In this paper, we present a novel design criterion for low-density parity-check (LDPC)-coded modulations based on the concatenation of an LDPC code with a coded modulator (CM) tailored for the specific transmission channel. Although we use an analysis based on extrinsic information transfer (EXIT) charts, we focus on the bit error rate (BER) performance as opposed to the convergence threshold. ...
