Article Synopsis
  • Mitochondria play a crucial role in cell functions and have their own genome (mtDNA), which is significant for stem cell differentiation, particularly in neural stem cells (NSCs).
  • In our study, we observed that as NSCs differentiate, their mtDNA content dramatically increases, even though mitochondrial transcription factor A levels remain unchanged.
  • By inhibiting mtDNA replication, we found that while neurogenesis was significantly reduced, gliogenesis was not affected, indicating that mtDNA replication is vital for the development of neurons in fetal NSCs but operates through mechanisms unrelated to energy production or reactive oxygen species levels.

VERSES AI Research Lab, Los Angeles, CA, 90016, USA; School of Engineering and Informatics, University of Sussex, Brighton, UK.

This paper concerns structure learning or discovery of discrete generative models. It focuses on Bayesian model selection and the assimilation of training data or content, with a special emphasis on the order in which data are ingested. A key move-in the ensuing schemes-is to place priors on the selection of models, based upon expected free energy.

Everyday life requires an adaptive balance between distraction-resistant maintenance of information and the flexibility to update this information when needed. These opposing mechanisms are proposed to be balanced through a working memory gating mechanism. Prior research indicates that obesity may elevate the risk of working memory deficits, yet the underlying mechanisms remain elusive.

During the COVID-19 pandemic, people with multiple sclerosis (MS) and their healthcare providers have faced unique challenges related to the interaction between SARS-CoV-2, underlying neurological disease and the use of disease-modifying treatments (DMTs). Key concerns arose, primarily related to the possibility that SARS-CoV-2 infection could trigger the initial demyelinating event or exacerbate disease activity. Another major concern was the safety and efficacy of the COVID-19 vaccines, especially for patients undergoing specific treatments that could weaken their antibody responses.

Lead halide perovskites have emerged as platforms for exciton-polaritonic studies at room temperature, thanks to their excellent photoluminescence efficiency and synthetic versatility. In this work, we find proof of strong exciton-photon coupling in cavities formed by the layered crystals themselves, a phenomenon known as the self-hybridization effect. We use multilayers of high-quality Ruddlesden-Popper perovskites in their 2D crystalline form, benefiting from their quantum-well excitonic resonances and the strong Fabry-Pérot cavity modes resulting from the total internal reflection at their smooth surfaces.

Plant responses to environmental heterogeneity depend on life-history traits, which could relate to phenotypical and genetic characteristics. To elucidate this relationship, we examined the variation in population genetics and functional traits of short- and long-lived species that are co-occurring in the steppes of Mongolia. Mongolian steppes represent stressful and water-limited habitats, demanding phenotypic modifications in the short term and/or genetic adaptation in the long term.

Article Synopsis
  • - Pathogenic variants (PVs) in the EPAS1 gene, which influences the hypoxia-inducible factor HIF-2α, are linked to about 3%-6% of pheochromocytoma and paragangliomas (PPGLs), either as standalone tumors or as part of Pacak-Zhuang Syndrome (PZS) which may include additional symptoms like polycythemia and somatostatinoma.
  • - The mutations in EPAS1 allow HIF-2α to escape from degradation processes, leading to its accumulation and activation of genes that promote tumor formation, particularly in those diagnosed in their second or third decade of life, with a higher prevalence in females.

We demonstrate the excitation of the gyrotropic mode in a magnetostrictive vortex by time-varying strain. The vortex dynamics is driven by a time-varying voltage applied to the piezoelectric substrate and detected electrically by spin rectification at subthreshold values of rf current. When the frequency of the time-varying strain matches the gyrotropic frequency at a given in-plane magnetic field, the strain-induced in-plane magnetic anisotropy leads to a resonant excitation of the gyration dynamics in the magnetic vortex.

  • The study investigates the associated production of Higgs and W bosons, focusing on how the relative signs of the Higgs couplings to W and Z bosons impact the process.
  • Two specific searches were conducted using large amounts of collision data from the LHC to analyze different coupling scenarios: one for opposite-sign couplings and another for same-sign (standard model-like) couplings.
  • The results significantly exclude the opposite-sign coupling hypothesis and set a strict upper limit on the production rate of this process compared to standard model predictions.

A platform-agnostic deep reinforcement learning framework for effective Sim2Real transfer towards autonomous driving.

Commun Eng

October 2024

Chair of Econometrics and Statistics, esp. in the Transport Sector, Technische Universität Dresden, Dresden, Germany.

Autonomous driving presents unique challenges, particularly in transferring agents trained in simulation to real-world environments due to the discrepancies between the two. To address this issue, here we propose a robust Deep Reinforcement Learning (DRL) framework that incorporates platform-dependent perception modules to extract task-relevant information, enabling the training of a lane-following and overtaking agent in simulation. This framework facilitates the efficient transfer of the DRL agent to new simulated environments and the real world with minimal adjustments.
