Algorithmic Support for Railway Disruption Management [PDF]

Disruptions of a railway system are responsible for longer travel times and much discomfort for the passengers. Since disruptions are inevitable, the railway system should be prepared to deal with them effectively.

Bridging Horizontal to Vertical Radiative Cooling

Advanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Smart train control and monitoring system with predictive maintenance and secure communications features

Transportation Research Interdisciplinary Perspectives
Predictive maintenance is a proactive and data-driven approach to service maintenance that aims to identify potential problems before they occur. Modern trains have a sophisticated train control and monitoring system (TCMS), a vehicle processing unit to ...

Import of Rolling Stock to Poland [PDF]

, 2019
The authors examined the role of rolling stock import and its elements in meeting the needs of the Polish rail market and the sources of the imported rolling stock. The time range of the research covered the years 1945–2017, but due to different economic

Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration

Advanced Science, EarlyView.
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

Bacteria‐Derived 1‐Allylpiperazine Alleviates Symptoms of Parkinson's Disease Model by Promoting Autophagy

Advanced Science, EarlyView.
Parkinson's disease currently has no disease‐modifying therapies. In Caenorhabditis elegans, Escherichia coli E8 alleviates α‐synuclein‐provoked PD‐related defects through its bioactive metabolite 1‐ALPP, which combats PD by triggering AMPK/mTOR/HLH‐30‐dependent autophagy and suppressing α‐synuclein LLPS‐mediated fibrillization.

Performance and Environmental Impact of Flexible Temperature Sensors on Cellulose‐Based Substrate

Advanced Electronic Materials, EarlyView.
Toward low‐environmental‐impact approach to thin‐film sensors fabrication using natural ingredient‐based triacetyl cellulose (TAC) substrate. Temperature sensors are fabricated and characterized based on thermal and mechanical performance. Substrate recovery is demonstrated by facile dissolution of a Mo‐based sensor in deionized water.
