Almost Global Stabilization of Curvature-Nullifiable Mechanical Systems via Pure Mechanical Feedback

open access: yesApplied Sciences
Mechanical control systems structure, derived from Euler–Lagrange dynamics, is directly tied to physically meaningful coordinates such as joint angles, positions, and velocities. This work investigates when a mechanical control system can be transformed,

In a land far, far away: writing (in) French Polynesia

open access: yesMatraga, 2019
This article approaches, from a historical perspective, the contemporary literature of French Polynesia and the themes that are particular to it, a consequence of the complex relationship between the region and France.

Generalized Painleve-Gullstrand descriptions of Kerr-Newman black holes

open access: yes, 2011
Generalized Painleve-Gullstrand metrics are explicitly constructed for the Kerr-Newman family of charged rotating black holes. These descriptions are free of all coordinate singularities; moreover, unlike the Doran and other proposed metrics, an extra ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

open access: yesMolecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Characteristics of geological evolution based on the multifractal singularity theory: A case study of Heyu granite and Mesozoic tectonics

open access: yesOpen Geosciences
Tectonic movement and magmatic activity are complex geological processes resulting from the interaction of multiple factors. These processes are often characterized by local singularities with nonlinear characteristics.

DU BOIS COMPLEXES OF CONES OVER SINGULAR VARIETIES, LOCAL COHOMOLOGICAL DIMENSION, AND K-GROUPS

open access: yesRevue Roumaine Mathematiques Pures Appliquees
We compute the Du Bois complexes of abstract cones over singular varieties, and use this to describe the local cohomological dimension and the non-positive K-groups of such cones.

Singularities in optimal structural design [PDF]

open access: yes
Singularity conditions that arise during structural optimization can seriously degrade the performance of the optimizer. The singularities are intrinsic to the formulation of the structural optimization problem and are not associated with the method of ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Bosonic near-CFT1 models from Fock-space fluxes

open access: yesJournal of High Energy Physics
We construct a family of near-CFT1 models with a conserved U(1) charge, whose basic degrees of freedom are canonical bosons. The Sachdev-Ye-Kitaev (SYK) model — the first microscopic model that realizes the near-CFT1 dynamics — is based on random p-local
