In this article, we focus on the cooperative multi-user network model and propose a relay-assisted partial packet recovery scheme in which asynchronous interleave-division multiple-access (IDMA) with iterative chip-by-chip multiuser detection (MUD) is used for the recovery of partial packets from multiple sources. In packet transmission, only a few erroneous bits may cause the entire packet to ...

We consider the inverse problem of identifying locations and certain properties of small inhomogeneities in a homogeneous background medium from boundary measurements on a part of the boundary or dynamic boundary measurements for a finite time interval. Using as weights particular background solutions we develop asymptotic methods based on an appropriate averaging of the data. Short title: Reco...

Fluctuations in soil moisture create drying-rewetting events affecting the activity of microorganisms. Microbial responses to drying-rewetting are mostly studied in soils that are air-dried before rewetting. Upon rewetting, two patterns of bacterial growth have been observed. In the Type 1 pattern, bacterial growth rates increase immediately in a linear fashion. In the Type 2 pattern, bacterial...

Two patients with subacute arsenic neuropathy are described and the results of serial conduction velocity determinations from the very early stages of the illness to partial recovery are reported. Sensory and motor deficits were maximal within four weeks of the estimated time of exposure. Recovery was slow, with only partial improvement of the neurological deficits two years after onset of the ...

Introduction Diffusion weighted imaging (DWI) allows the determination of the apparent diffusion coefficient (ADC). Since several tissue compartments may be present in a voxel, e.g. tissue and cerebrospinal fluid [1] or tissue and blood [2], the measured ADC is an averaged value, weighted by these partial volumes. To reduce this partial volume effect, several investigators tried to null the mag...

We present PASSSign, a variant of the prior PASS and PASS-2 proposals, as a candidate for a practical post-quantum signature scheme. Its hardness is based on the problem of recovering a ring element with small norm from an incomplete description of its Chinese remainder representation. For our particular instantiation, this corresponds to the recovery of a signal with small infinity norm from a...

In this paper, we examine the robustness of a relax-and-round k-means clustering procedure, a method for clustering subgaussian mixtures using semidefinite programming first introduced in [MVW16]. We are interested in the robustness of the algorithm when there is an adversarial corruption of N points each through distance at most R0. We show that under such corruption this specific algorithm we...

The hydrophobic recovery of polydimethylsiloxane elastomers was studied after exposure to partial electrical discharge. Silicone elastomers that were thoroughly extracted of free oligomeric impurities as well as those deliberately contaminated with low molecular weight (LMW) silicone fluids were used for these studies. Contact angle and X-ray photoelectron spectroscopy revealed that the recover...

by Shiva Prasad Kotagiri In many communication scenarios, the communicating parties typically have some knowledge or attempt to learn about the time-varying environment or the channel over which communication takes place. To understand these models, it is important to study the fundamental performance limits of state-dependent channels whose probabilistic input-output relationship depends on a ...
