Quantum chaos for nonstandard symmetry classes in the Feingold-Peres model of coupled tops [PDF]
, 2017 We consider two coupled quantum tops with angular momentum vectors $\mathbf{L}$ and $\mathbf{M}$. The coupling Hamiltonian defines the Feinberg-Peres model which is a known paradigm of quantum chaos.

Nonstandard models and analytic equivalence relations [PDF]
Proceedings of the American Mathematical Society, 1997 We improve a result of Hjorth concerning the nature of thin analytic equivalence relations. The key lemma uses a weakly compact cardinal to construct certain nonstandard models, which Hjorth obtained using # \# ’s.

Crossover dynamics of climate change models: Numerical simulations
Alexandria Engineering Journal, 2023 In this paper, two new climate change mathematical models are extended using the stochastic-deterministic piecewise hybrid fractional derivatives, where the hybrid fractional order operator is applied to extend the deterministic model and the fractional ...

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories
Advanced Engineering Materials, EarlyView.A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

RaPID Selection of Backbone Macrocyclic Peptides Targeting Akt2
Angewandte Chemie, EarlyView.Backbone macrocyclic peptide library (BMP) library was screened against Akt2 via RaPID to discover potent BMPPakti‐3 (IC50 = 34 nM). ABSTRACT Backbone‐cyclic peptides (BMPs) are an attractive class of molecules appeared in diverse natural bioactive products. However, mRNA display technology coupled with ribosomal synthesis is intrinsically inapplicable

Mothers’ Nonstandard Work Schedules, Economic Hardship, and Children’s Outcomes
SociusThe authors investigate the moderating role of three dimensions of economic hardship on the relationship between maternal nonstandard work schedules (working evening, nights, or weekends) and children’s behavioral and cognitive outcomes at age five in ...

Annals of Gastroenterological Surgery, EarlyView.Preoperative CT based on lymph node size shows moderate accuracy for detecting nodal metastasis in colon cancer. In this meta‐analysis of 29 studies (5,634 patients), pooled sensitivity and specificity were 0.69 and 0.66. Size‐based CT alone has limited value for clinical decision‐making.
