Logical Foundations of Multilevel Databases

open access: yes, 1999
International audienceIn this paper, we propose a formal model for multilevel databases. This model aims at being a generic model, that is it can be interpreted for any kind of database (relational, object-oriented...). Our model has three layers.

Positive Feedback Loop of Histone Lactylation‐Driven HNRNPC Promotes Autophagy to Confer Pancreatic Ductal Adenocarcinoma Gemcitabine Resistance

open access: yesAdvanced Science, EarlyView.
Histone 3 lysine18 lactylation (H3K18la) drives heterogeneous nuclear ribonucleoprotein C (HNRNPC) overexpression, activating autophagy to mediate gemcitabine resistance by stabilizing TNF receptor‐associated factor 6 (TRAF6) mRNA. Concurrently, HNRNPC stabilizes aldehyde dehydrogenase 1 family member A3 (ALDH1A3) mRNA, which enhances glycolysis and ...

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

open access: yesAdvanced Science, EarlyView.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

Artificial Neuron Based on Electrical Anisotropy from WSe2 Field Effect Transistors

open access: yesAdvanced Science, EarlyView.
An artificial neuron was realized based on the anisotropic mobility of WSe2. Dendritic and axon‐multisynaptic performance of a neuron was achieved with optical and voltage pulses. Recognition accuracy of handwritten digits was obtained to 97% based on the synaptic weight of an artificial neuron.
