We have studied the mesoscopic shape fluctuations in aligned multilamellar stacks of 1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine bilayers using the neutron spin-echo technique. The corresponding in plane dispersion relation tau-1(q//) at different temperatures in the gel (ripple, Pbeta') and the fluid (Lalpha) phase of this model system has been determined. Two relaxation processes, one at ...

Abstract. Zero-sum problems for abelian groups and covers of the integers by residue classes, are two different active topics initiated by P. Erdős more than 40 years ago and investigated by many researchers separately since then. In an earlier announcement [Electron. Res. Announc. Amer. Math. Soc. 9(2003), 51-60], the author claimed some surprising connections among these seemingly unrelated f...

We consider the distribution of spacings between consecutive elements in subsets of Z/qZ, where q is highly composite and the subsets are defined via the Chinese Remainder Theorem. We give a sufficient criterion for the spacing distribution to be Poissonian as the number of prime factors of q tends to infinity, and as an application we show that the value set of a generic polynomial modulo q ha...

The nonlinear behavior of the Toroidal Alfvén Eigenmode (TAE) driven unstable by energetic ions in the Tokamak Fusion Test Reactor (TFTR) [Phys. Plasmas 1, 1560 (1994)] is studied. The evolution of instabilities can take on several scenarios: a single mode or several modes can be driven unstable at the same time, the spectrum can be steady or pulsating and there can be negligible or anomalous l...

Let pj, q,, denote the self-adjoint operators -iajax, and multiplication by x, on L’(W), respectively. Let H,, = (l/2) xyr= r o,(pf +qj-l)whereo,>O,andletPbe a polynomial in the q’s that is bounded below. The existence and uniqueness problems are considered for H, + IF’(q) renormalized relative to its own ground state. For example, suppose that P has degree 2d and P(q) >~(qf + ... +qz)“-k for s...

This letter proposes a novel ultrawideband plane wave generator (PWG) design methodology suitable for low-cost small anechoic chamber. Several strategies are proposed to handle various crucial concerns in practice make the reliable and robust. Specifically, subarray-based amplitude-only excitation method is capable of reducing required number control channels without need phase shifters, which ...

The numerical solution of singular eigenvalue problems is complicated by the fact that small perturbations coefficients may have an arbitrarily bad effect on accuracy. However, it has been known for a long time such are exceptional and standard solvers, as QZ algorithm, tend to yield good accuracy despite inevitable presence roundoff error. Recently, Lotz Noferini quantified this phenomenon int...

Abstract We investigate the prospect of discovering Flavour Changing Neutral Current (FCNC) couplings via two production processes yielding trilepton signals: top quark pair pp\to t\bar{t} with one decaying to Z boson and light jet anomalous single plus process tZ . study these channels at various successors Large Hadron Collider (LHC), i.e., approved High-Luminosity LHC (HL-L...

In recent years, error mining approaches have been proposed to identify the most likely sources of errors in symbolic parsers and generators. However the techniques used generate a flat list of suspicious forms ranked by decreasing order of suspicion. We introduce a novel algorithm that structures the output of error mining into a tree (called, suspicion tree) highlighting the relationships bet...
