Acta Crystallographica Section A, Volume 79, Issue 6, Page 570-586, November 2023., 2023 A mathematical toy model of chiral spiral cyclic twins is presented, describing a family of deterministically generated aperiodic point sets. Its individual members depend solely on a chosen pair of integer parameters, a modulus m and a multiplier μ, comprising local features of both periodic and aperiodic crystals.

On Characterizations of Weighted Harmonic Bloch Mappings and Its Carleson Measure Criteria
Journal of Function Spaces, Volume 2023, Issue 1, 2023., 2023 For α > 0, several characterizations of the α‐Bloch spaces of harmonic mappings are given. We also obtain several similar characterizations for the closed separable subspace. As an application, we give relations between BHα and Carleson’s measure.

Pure discrete spectrum and regular model sets on some non‐unimodular substitution tilings
Acta Crystallographica Section A, Volume 78, Issue 5, Page 437-451, September 2022., 2022 The equivalence between pure discrete spectrum and regular model sets on some non‐unimodular substitution tilings is established. This will help to provide useful information about the cut‐and‐project scheme used in the description of quasiperiodic structures.Substitution tilings with pure discrete spectrum are characterized as regular model sets whose

Coordination sequences of crystals are of quasi‐polynomial type
Acta Crystallographica Section A, Volume 77, Issue 2, Page 138-148, March 2021., 2021 It is proved that the coordination sequence of the graph obtained from a crystal is of quasi‐polynomial type, as had been postulated by Grosse‐Kunstleve et al. [Acta Cryst. (1996), A52, 879–889] in their study of coordination sequences of zeolites.The coordination sequence of a graph measures how many vertices the graph has at each distance from a ...

Bayesian inference in a class of partially identified models
Quantitative Economics, Volume 7, Issue 2, Page 329-366, July 2016., 2016 This paper develops a Bayesian approach to inference in a class of partially identified econometric models. Models in this class are characterized by a known mapping between a point identified reduced‐form parameter μ and the identified set for a partially identified parameter θ.

Study of B¯d,s⁎0→Dd,s+M- Decays with QCD Factorization Approach
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 Motivated by the b‐physics experiments at running LHC and upcoming SuperKEKB/Belle‐II, the nonleptonic B¯q⁎0→Dq+M- (q = d, s and M = π, K, ρ, K⁎) weak decays are studied within QCD factorization framework. The observables of these decay modes are first predicted.

A Review on Fatigue Life Prediction Methods for Metals
Advances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016 Metallic materials are extensively used in engineering structures and fatigue failure is one of the most common failure modes of metal structures. Fatigue phenomena occur when a material is subjected to fluctuating stresses and strains, which lead to failure due to damage accumulation. Different methods, including the Palmgren‐Miner linear damage rule‐

πe3 Form Factor f− Near the Mass Shell
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 The generalized Ward‐Takahashi identity (gWTI) in the pion sector for broken isotopic symmetry is derived and used for the model‐independent calculation of the longitudinal form factor f− of the πe3 vector vertex. The on‐shell f− is found to be proportional to the mass difference of the pions and the difference between the vector isospin T = 1 and ...

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 We investigate heavy haze episodes (with dense concentrations of atmospheric aerosols) occurring around Beijing in June, when serious air pollution was detected by both satellite and ground measurements. Aerosol retrieval is achieved by radiative transfer simulation in an Earth atmosphere model.
