Origin of the Laser‐Induced Picosecond Spin Current Across Magnetization Compensation in Ferrimagnetic GdCo

open access: yesAdvanced Optical Materials, EarlyView.
Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

RTXP : A Localized Real-Time Mac-Routing Protocol for Wireless Sensor Networks [PDF]

open access: yesN° RR-7978 (2012), 2012
Protocols developed during the last years for Wireless Sensor Networks (WSNs) are mainly focused on energy efficiency and autonomous mechanisms (e.g. self-organization, self-configuration, etc). Nevertheless, with new WSN applications, appear new QoS requirements such as time constraints.

Antibiotic–Polycationic Peptide Conjugation as an Effective Strategy to Overcome Daptomycin Resistance

open access: yesAdvanced Therapeutics, EarlyView.
Antimicrobial resistance necessitates the development of new antibiotics with “resistance‐breaking” properties. In this study, conjugation of polycationic peptides is proven to represent a versatile strategy for the fast and affordable reactivation of daptomycin.

Apoptotic Vesicles Derived from Mesenchymal Stem Cells Ameliorate Hypersensitivity Responses via Inducing CD8+ T Cells Apoptosis with Calcium Overload and Mitochondrial Dysfunction

open access: yesAdvanced Science, EarlyView.
The therapeutic potential of ApoVs derived from stem cells from human exfoliated deciduous teeth (SHED‐ApoVs) in the treatment of CD8+ T cell‐mediated hypersensitivity reactions is noteworthy. SHED‐ApoVs are capable of fusing with the plasma membrane of CD8+ T cells, which subsequently triggers a series of events characterized by calcium overload ...

α‐Synuclein Pathology Spreads in a Midbrain–Hindbrain Assembloid Model

open access: yesAdvanced Science, EarlyView.
A novel midbrain–hindbrain assembloid model demonstrates the spread of α‐synuclein pathology, a hallmark of Parkinson's disease, mimicking Braak's hypothesis. This model reveals how pathology propagates from the hindbrain to the midbrain, inducing synaptic changes and early signs of neuronal vulnerability. It offers an innovative platform for exploring
