Combinatorial Limitations of Averageradius List Decoding
"... We study certain combinatorial aspects of listdecoding, motivated by the exponential gap between the known upper bound (of O(1/γ)) and lower bound (of Ωp(log(1/γ))) for the listsize needed to list decode up to error fraction p with rate γ away from capacity, i.e., 1−h(p)−γ (here p ∈ (0, 1 2) and ..."

) codewords with low “average radius. ” The standard notion of listdecoding corresponds to working with the maximum distance of a collection of codewords from a center instead of average distance. The averageradius form is in itself quite natural; for instance, the classical Johnson bound in fact implies
Split States, Entropy Enigmas, Holes and Halos
, 2007
"... We investigate degeneracies of BPS states of Dbranes on compact CalabiYau manifolds. We develop a factorization formula for BPS indices using attractor flow trees associated to multicentered black hole bound states. This enables us to study background dependence of the BPS spectrum, to compute e ..."

We point out a likely breakdown of the OSV conjecture at small gtop (in the large background CY volume limit), due to the surprising phenomenon that for sufficiently large background Kähler moduli, a charge ΛΓ supporting single centered black holes

. The effects of ring’s outer radius growth rate and rolls sizes on the uniformities of PEEQ and temperature distributions, average rolling force, and average rolling moment were studied. The results indicate that the PEEQ at the inner layer and outer layer of rolled ring are larger than that at the middle
Combinatorial limitations of a strong form of list decoding
 Electronic Colloquium on Computational Complexity (ECCC
, 2012
"... We prove the following results concerning the combinatorics of list decoding, motivated by the exponential gap between the known upper bound (of O(1/γ)) and lower bound (of Ωp(log(1/γ))) for the listsize needed to decode up to radius p with rate γ away from capacity, i.e., 1 − h(p) − γ (here p ∈ (0 ..."

Study of charged soot aggregates formed by benzene pyrolysis.
"... Soot formation during benzene pyrolysis is of interest due to use of fuels with increased aromatic content resulting in high level of particulate emissions from vehicular exhausts, furnaces, and manufacturing processes relatively to those emissions from low C/H ratio fuels. This work is aimed at vid ..."

A note on a generalized form of the Laplacian and of subLaplacians
"... Abstract. In this note we prove a recent conjecture of Hasson [11]: we show that, for a locally integrable function u, a sufficient condition to be harmonic is that lim r→0+ r−2(Mru − u) = 0 in the weak sense of distributions (Mr being the averaging operator on balls of radius r). We also extend th ..."

Crystallization in Al88RE8Ni4 Glass Forming Alloys
"... The results from transmission electron microscopy (TEM) microstructural studies of devitrified amorphous alloys with a composition Al88RE8Ni4 are presented as a function of average rare earth atomic radii (between 1.76 to 1.87 Å). Rare earth elements {Gd, Er, and La} were cosubstituted to vary the ..."

However, doping the dimyristoyl/ dihexanoyl system with both Ca21 and DMPG resulted in ULVs whose hRoi was found to be Clp dependent. The hRoi of DMPGdoped ULVs remained unchanged over an extended period of time
