Efficient optimisation of physical reservoir computers using only a delayed input.

Commun Eng

January 2025

Laboratoire d'Information Quantique CP224, Université libre de Bruxelles (ULB), Av. F. D. Roosevelt 50, 1050, Bruxelles, Belgium.

Reservoir computing is a machine learning algorithm for processing time dependent data which is well suited for experimental implementation. Tuning the hyperparameters of the reservoir is a time-consuming task that limits is applicability. Here we present an experimental validation of a recently proposed optimisation technique in which the reservoir receives both the input signal and a delayed version of the input signal.

HIV-associated neurocognitive disorders (HAND) and viral reservoirs in the brain remain a significant challenge. Despite their importance, the mechanisms allowing HIV-1 entry and replication in the central nervous system (CNS) are poorly understood. Here, we show that α-synuclein and (to a lesser extent) Aβ fibrils associated with neurological diseases enhance HIV-1 entry and replication in human T cells, macrophages, and microglia.

Although intense research effort is seeking to address which brain areas fire and connect to each other to produce complex behaviors in a few living primates, little is known about their evolution, and which brain areas or facets of cognition were favored by natural selection. By developing statistical tools to study the evolution of the brain cortex at the fine scale, we found that rapid cortical expansion in the prefrontal region took place early on during the evolution of primates. In anthropoids, fast-expanding cortical areas extended to the posterior parietal cortex.

Laboratory of Cancer Epigenetics, Faculty of Medicine, ULB-Cancer Research Center (U-CRC), Université libre de Bruxelles (ULB), Institut Jules Bordet, Brussels, Belgium. Electronic address:

The marking of DNA, histones, and RNA is central to gene expression regulation in development and disease. Recent evidence links N6-methyladenosine (mA), installed on RNA by the METTL3-METTL14 methyltransferase complex, to histone modifications, but the link between mA and DNA methylation remains scarcely explored. This study shows that METTL3-METTL14 recruits the DNA methyltransferase DNMT1 to chromatin for gene-body methylation.

Introduction: In this review, we evaluate the role of stromal tumor-infiltrating lymphocytes (sTILs) as a biomarker in human epidermal growth factor receptor 2 (HER2)-positive breast cancer, exploring the prognostic and predictive potential in various treatment settings.

Methods: Data from multiple clinical trials in the early and metastatic settings, focusing on TILs' correlation with pathologic complete response (pCR), progression-free survival (PFS), and overall survival across early and metastatic HER2-positive breast cancer were summarized. This review also discusses TILs' assessment methods, interobserver variability, and emerging technologies to assess TILs.

The analysis of mineral oil aromatic hydrocarbons (MOAH) in vegetable oils is currently associated with high uncertainty due to various factors ranging from sample preparation to data interpretation. One significant factor is the coelution of biogenic compounds of terpenic origin with the MOAH fraction during chromatographic analysis. The common purification method is epoxidation, a chemical reaction that changes the polarity of the interferences, allowing their separation from MOAH.

Background: The periosteum consists of an outer fibrous layer and an inner cellular layer, where bone cells reside. Hence, it has been suggested that applying periosteum to a periodontal defect may help new bone formation. The purpose of this case study is to present the clinical and radiographic outcomes of a vestibular regenerative approach and the application of a connective tissue graft (CTG) with periosteum to improve the periodontal prognosis of a pathologically migrated hopeless tooth with an endo-periodontal lesion (EPL).

Department of Anaesthesiology and Intensive Care, Bicetre hospital, Assistance Publique Hôpitaux de Paris (AP-HP), Le Kremlin Bicetre, France.

Intravenous fluid is administered during high-risk surgery to optimize stroke volume (SV). To assess ongoing need for fluids, the hemodynamic response to a fluid bolus is evaluated using a fluid challenge technique. The Acumen Assisted Fluid Management (AFM) system is a decision support tool designed to ease the application of fluid challenges and thus improve fluid administration during high-risk surgery.

The gut microbiota is unanimously acknowledged as playing a central role in human health, notably through the production of various metabolites, including short-chain fatty acids, secondary bile acids, vitamins or neurotransmitters. Beyond contributing to gut health itself, these microbial metabolites significantly impact multiple organ systems by participating in key signaling pathways along the well documented gut-organ axes. Chemicals ingested through food might interact with our gut microbiota, altering metabolites production with consequences on health.

In April 2024, the Adult Immunization Board convened a technical meeting to explore the latest strategies and identify exemplary approaches regarding the implementation of vaccines for adults into Europe's National Immunization Programs (NIPs). The meeting was built around three pillars: decision making for introducing a new vaccine, implementation, monitoring, and evaluation. The increasing number of new vaccines available in a context of competing health priorities warrants transparent and evidence-based decision-making processes for vaccine introduction.

Biological invasions are a major threat to biodiversity, ecosystem functioning and nature's contributions to people worldwide. However, the effectiveness of invasive alien species (IAS) management measures and the progress toward achieving biodiversity targets remain uncertain due to limited and nonuniform data availability. Management success is usually assessed at a local level and documented in technical reports, often written in languages other than English, which makes such data notoriously difficult to collect at large geographic scales.

Purpose: Cochlear implants (CI) are the most successful bioprosthesis in medicine probably due to the tonotopic anatomy of the auditory pathway and of course the brain plasticity. Correct placement of the CI arrays, respecting the inner ear anatomy are therefore important. The ideal trajectory to insert a cochlear implant array is defined by an entrance through the round window membrane and continues as long as possible parallel to the basal turn of the cochlea.
