Runaway brain‐culture coevolution as a reason for larger brains: Exploring the “cultural drive” hypothesis by computer modeling

Ecology and Evolution, 2020
Scale and tempo of brain expansion in the course of human evolution implies that this process was driven by a positive feedback. The “cultural drive” hypothesis suggests a possible mechanism for the runaway brain‐culture coevolution wherein high‐fidelity

Robotic Control for Human–Robot Collaborative Assembly Based on Digital Human Model and Reinforcement Learning

Advanced Robotics Research, EarlyView.
This work presents a robotic control method for human–robot collaborative assembly based on a biomechanics‐constrained digital human model. Reinforcement learning is used to generate physiologically plausible human motion trajectories, which are integrated into a virtual environment for robot control learning.

Intervening to eliminate the centre-effect variation in home dialysis use: a synopsis of Inter-CEPt, an exploratory sequential mixed-methods study

Health and Social Care Delivery Research
Background There is a substantial variation in the use of home dialysis between kidney services, which disproportionally affects people from ethnic minorities and socioeconomically deprived areas.

CPS cascade failure model construction and path optimization for novel power system

Diance yu yibiao
The proportion of new energy in novel power system is gradually increasing, leading to a development trend of low carbonization, intelligence, diversification, safety and economy in novel power system, and an increasing demand for network security.

Markov random fields and Markov chains on trees [PDF]

, 1981
We consider probability measures on a space S(^A) (where S and A are countable and the σ-field is the natural one) which are Markov random fields with respect to a given neighbour relation ~ on A.

Dissecting the Ecological Structure of Health and Disease in the Global Gut Microbiome

Advanced Science, EarlyView.
We introduce Wiredancer, a framework that identifies three continuous ecological factors of the gut microbiota. These factors exhibit distinct patterns across health and disease, jointly capturing disrupted ecological stability and offering a new perspective for precision diagnostics and therapeutic strategies.

The Expected Markov Property for Quantum Markov Fields

Milan Journal of Mathematics, 2023
The difficulty to construct a quantum theory of Markov processes is rooted in the fact that, given a von Neumann algebra \(\mathcal{A}\) with a state \(\phi\) and a von Neumann sub-algebra \(\mathcal{B}\), a conditional expectation \(E\), from \(\mathcal{A}\) onto \(\mathcal{B}\) compatible with \(\phi\), namely such that \(\phi\circ E = \phi\), in ...

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

Advanced Science, EarlyView.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

La transformation numérique : quelques procès en cours

Revue Française des Sciences de l’Information et de la Communication, 2013
In this paper we try to examine a number of requisites for a "general theory of narrative" and to consider some difficulties, particularly of the semiotic order, in connection with the great digital transformation.
