In 2006, Hao and Zieliński proposed a two-round anonymous veto protocol (called AV-net), which provided exceptional efficiency compared to related techniques. this study, the authors add self-tallying function AV-net, making it general-purpose voting protocol. The new works in same setting as AV-net – requires no trusted third parties or private channels, participants execute by sending public messages. Compared with protocols past work, is significantly more efficient terms of number...
Perovskite-like materials exhibit desirable photophysical and electric properties that make them suitable for a remarkable breadth of applications in electronics physics. In this contribution, we report on the multiphase ferroelectric ferroelastic phenomena pyrrolidinium-based hybrid metal–organic material: (C4H8NH2)3[Sb2Cl9]. The title compound is first pyrrolidinium derivative within halobismuthates(III) haloantimonates(III) families featured by property. From structural point view,...
Two hybrid crystals imidazolium iodoantimonate(<sc>iii</sc>) and iodobismuthate(<sc>iii</sc>) have been synthesized characterized in a wide temperature range (100–350 K) by means of X-ray diffraction, dielectric spectroscopy, proton magnetic resonance, FT-IR spectroscopy optical observations.
Novel room-temperature ferroelectric crystals with complex sequences of phase transitions.
Level schemes of $^{111}\mathrm{Rh}$ and $^{113}\mathrm{Rh}$ are proposed from the analysis $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidence data a $^{252}\mathrm{Cf}$ spontaneous fission source with Gammasphere. These have highest excitation energies spins yet established in these nuclei, as well weakly populated bands not reported earlier fission-$\ensuremath{\gamma}$ work. From data, information on shapes is inferred. By...
Diisobutylammonium bromide is found to be a unique improper ferroelastic in which the elastic degrees of freedom seem play essential role, giving rise domain pattern resembling that martensitic phase transitions. A weak canted ferroelectricity turns out switchable by an electric field.
The generalization mystery in deep learning is the following: Why do over-parameterized neural networks trained with gradient descent (GD) generalize well on real datasets even though they are capable of fitting random comparable size? Furthermore, from among all solutions that fit training data, how does GD find one generalizes (when such a well-generalizing solution exists)? We argue answer to both questions lies interaction gradients different examples during training. Intuitively, if...
In the set agreement problem, n processes have to decide on at most n-1 of proposed values. This paper shows that anti-Omega failure detector is both sufficient and necessary solve in an asynchronous shared-memory system. Each query returns a single process id; specification ensures there correct whose id returned only finitely many times.
Two novel guanidinium iodoantimonate(III) and iodobismuthate(III) crystals, [C(NH2)3]3[Sb2I9] [C(NH2)3]3[Bi2I9], have been synthesized their structures determined by means of single-crystal x-ray diffraction studies at three temperatures (293, 348 362 K). Both compounds appeared to be isomorphous in corresponding phases. The crystal structure the title is composed discrete M2I93− (M = Sb, Bi) anions C(NH2)3+ cations. A non-equivalence two cations has found. analogs exhibit a rich sequence...
A hydrogen-bonded metallocyanide-based (AZE)2(H3O)[Co(CN)6] framework was obtained by introducing a hydronium cation to the A2B(1)B(2)CN6-type structure. Simple K+/H3O+ substitution exchange three-dimensional structure of double-perovskite into two-dimensional layers containing open inorganic cages with strongly discontinuous improper ferroelastic phase transition.
We report combined density functional studies and thermodynamic considerations on Ti-related native defects in lithium borohydride sodium alanate. Ti atoms introduced into the bulk of LiBH(4) are thermodynamically unfavorable for all their oxidation states, while high states Ti(n+) cations may become stable NaAlH(4) at certain conditions. Neutral hydrogen vacancies interstitials or cation less than charged counterparts both compounds. In alanate, formation leads to changes coordination...

Abstract Defects can significantly affect performance of nanopatterned magnetic devices, therefore their influence on the material properties has to be understood well before is used in technological applications. However, this experimentally challenging due inability control defect characteristics a reproducible manner. Here, we construct micromagnetic model, which accounts for intrinsic and extrinsic defects associated with polycrystalline nature corrugated edges nanostructures. The...
An excited rotational band including seven new $\ensuremath{\gamma}$ transitions was identified in ${}^{97}\mathrm{Sr}$ from $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ coincidences the spontaneous fission of ${}^{252}\mathrm{Cf}.$ This band, built on 829.8-keV state, is interpreted as $\ensuremath{\nu}9/2[404]$ with a very deformed shape. The half-life state determined to be 265(27) ns present work. indicates that emptying upsloping ${g}_{9/2}$...
We demonstrate that a surface resonance (pseudosurface wave) may transform into true wave, i.e., acquire an infinite lifetime, at single isolated point within bulk band (radiative region) in model of stressed auxetic material. In contrast with the secluded supersonic elastic waves, one found here does not belong to dispersion line waves. Therefore we propose call it wave (ITSW). The ITSW manifests itself by deltalike peak local density states and anomalies reflection coefficients. phenomenon...
