Fermion localization and causality [PDF]
Il Nuovo Cimento A, 1992 The velocity of a fermion (neutrino) propagation from its source to its detector is investigated. It is shown that a simple approach to the problem in terms of the quantum packet spreading (Hegerfeldtet al.) is not applicable because the fermion cannot be localized in a bounded space region.

Local causal states and discrete coherent structures [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2018 Coherent structures form spontaneously in nonlinear spatiotemporal systems and are found at all spatial scales in natural phenomena from laboratory hydrodynamic flows and chemical reactions to ocean, atmosphere, and planetary climate dynamics. Phenomenologically, they appear as key components that organize the macroscopic behaviors in such systems ...

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Local d’Alembertian for causal sets
Physical Review DCausal set theory is an intrinsically nonlocal approach to quantum gravity, inheriting its nonlocality from Lorentzian nonlocality. This nonlocality causes problems in defining differential operators -- such as the d'Alembert operator, a cornerstone of any relativistic field theory -- within the causal set framework.

Local Search for Efficient Causal Effect Estimation
IEEE Transactions on Knowledge and Data Engineering, 2023 Causal effect estimation from observational data is a challenging problem, especially with high dimensional data and in the presence of unobserved variables. The available data-driven methods for tackling the problem either provide an estimation of the bounds of a causal effect (i.e. nonunique estimation) or have low efficiency.

Global and local aspects of causality in quantum mechanics
EPJ Web of Conferences, 2013 Quantum mechanics forces us to reconsider certain aspects of classical causality. The ‘central mystery’ of quantum mechanics manifests in different ways, depending on the interpretation. This mystery can be formulated as the possibility of selecting part

Molecular Oncology, EarlyView.Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Violation of causality in f(T) gravity
European Physical Journal C: Particles and Fields, 2017 In the standard formulation, the f(T) field equations are not invariant under local Lorentz transformations, and thus the theory does not inherit the causal structure of special relativity.
