Numerical measure of strong stability and strong quasistability in the vector problem of integer linear programming [PDF]
Computer Science Journal of Moldova, 1999 In this paper we consider a vector integer programming problem with the linear partial criteria. Numerical evaluations of two types of stability of the Pareto set have been found.

Congenital Malformations in the Moroccan Surveillance System: Contribution to Prevalence Estimation. [PDF]
Glob Health Epidemiol GenomBackground. Congenital malformations (CMs) are a group of structural or functional anomalies present at birth. These anomalies result in a high rate of mortality, morbidity, and disability in children. CMs are a major public health problem and place a heavy burden on healthcare systems in both developed and developing countries including Morocco, which

Quasistates and quasiprobabilities [PDF]
Physical Review A, 2018 The quasiprobability representation of quantum states addresses two main concerns, the identification of nonclassical features and the decomposition of the density operator. While the former aspect is a main focus of current research, the latter decomposition property has been studied less frequently. In this contribution, we introduce a method for the

Polynomial‐time universality and limitations of deep learning
Communications on Pure and Applied Mathematics, Volume 76, Issue 11, Page 3493-3549, November 2023., 2023 Abstract The goal of this paper is to characterize function distributions that general neural networks trained by descent algorithms (GD/SGD), can or cannot learn in polytime. The results are: (1) The paradigm of general neural networks trained by SGD is poly‐time universal: any function distribution that can be learned from samples in polytime can ...

Spectrum of quasistable states in a strong microwave field [PDF]
Physical Review A, 2014 When atoms are exposed to intense laser or microwave pulses ~10% of the atoms are found in Rydberg states subsequent to the pulse, even if it is far more intense than required for static field ionization. The optical spectra of the surviving Li atoms in the presence of a 38 GHz microwave field suggest how atoms survive an intense pulse.

Human Brain Mapping, Volume 44, Issue 6, Page 2158-2175, April 15, 2023., 2023 We highlight the replicable time‐resolved developmental and aging functional brain patterns in a systematic evaluation of over 47,000 youth and adult brains. Our study captured the most contrastive difference between the two life stages in a brain state that indicated coherent strengthening and modularization of functional coupling within the auditory,

Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023 Considering that the effect of solar radiation on the super‐high arch dam temperature field remains poorly studied, the calculation accuracy of dam temperature deformation is unable to be guaranteed accordingly. To address the issue, the solar radiation effect is adequately taken into consideration by proposing a practical calculation method based on ...

The moduli space of quasistable spin curves
Collectanea Mathematica, 2022 We study a compactification of the moduli space of theta characteristics, giving a modular interpretation of the geometric points and describing the boundary stratification. This space is different from the moduli space of spin curves. The modular description and the boundary stratification of the new compactification are encoded by a tropical moduli ...

Research on Productivity Evaluation Method Based on Shale Gas Well Early Flow Stage Data
Geofluids, Volume 2023, Issue 1, 2023., 2023 Since the accurate early gas well production regime is related to the production period and final productivity, it is crucial to make better use of early flow stage production data for gas well productivity evaluation. Absolute open flow potential (AOF) and estimated ultimate recovery (EUR) are essential parameters for evaluating the productivity of ...
