The purpose of this paper is to examine the alternative explanatory factors of the so-called long term care insurance puzzle, namely the fact that so few people purchase a long term care insurance whereas this would seem to be a rational conduct given the high probability of dependence and the high costs of long term care. For that purpose, we survey various theoretical and empirical studies of...

Given a sequence A = (a1, . . . , an) of real numbers, a block B of the A is either a set B = {ai, ai+1, . . . , aj} where i ≤ j or the empty set. The size b of a block B is the sum of its elements. We show that when each ai ∈ [0, 1] and k is a positive integer, there is a partition of A into k blocks B1, . . . , Bk with |bi − bj| ≤ 1 for every i, j. We extend this result in several directions.

A non-deterministic automaton running on infinite trees is unambiguous if it has at most one accepting run on every tree. The class of languages recognisable by unambiguous tree automata is still not well-understood. In particular, decidability of the problem whether a given language is recognisable by some unambiguous automaton is open. Moreover, there are no known upper bounds on the descript...

A manifestly supersymmetric nonperturbative matrix regularization for a twisted version of N = (8, 8) theory on a curved background (a two-sphere) is constructed. Both continuum and the matrix regularization respect four exact scalar supersymmetries under a twisted version of the supersymmetry algebra. We then discuss a succinct Q = 1 deformed matrix model regularization ofN = 4 SYM in d = 4, w...

Using high-field NMR, we have determined the magnitude of the nuclear quadrupole interaction in hexamethylene triperoxide diamine (HMTD), the explosive allegedly used in the London bombings of July 2005. The experimental quadrupolar coupling constant, 5.334 MHz, is in good agreement with quantum chemical calculations. The predicted single zero-field transition frequency should lie in a relative...

We have studied the atomic structure and the electronic properties of Ban clusters by the ab initio molecular dynamics method. We find that a structural transition to the bulk-like structure begins at Ba9 cluster, and the structures of the clusters are transferred to be icosahedral-like around n = 13. The relatively high stability for Ba4, Ba10 and Ba13 clusters are observed.

Solid-state NMR transitions involving outer energy levels of the spin-1 (14)N nucleus are immune, to first order in perturbation theory, to the broadening caused by the nuclear quadrupole interaction. The corresponding overtone spectra, when acquired in conjunction with magic-angle sample spinning, result in lines, which are just a few kHz wide, permitting the direct detection of nitrogen compo...

To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...
