Distribution of Pressures on Modified Stepped Spillway by Using Toothed-Steps

Engineering and Technology Journal, 2021
 A new stepped spillway shape was used in experimental work under the skimming flow regime by adding block (tooth) on the step.  The tooth-stepped spillway reduces the positive and negative pressure on steps close to the crest by a large amount and ...

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Improving the Quality of the Water Flowing over a Stepped Spillway in Open Canals by Increasing Its Degree of Aeration

Limnological Review
As spillways are hydraulic structures constructed for the safe release of floodwater from the upstream (US) side of a dam to the downstream side, or from the end of canals and drains to a lower stream, the upstream water flow of such structures gains ...

Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

Advanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Characteristics of Energy Dissipation for “V”-type Stepped Spillway

工程科学与技术, 2010
:A new type of stepped spillway with the plane layout similar to alphabet “V” was put forward. Numerical investigations were performed both for this type of stepped spillway and traditional stepped spillway.

Physical Modeling of an Aerating Stepped Spillway

, 2016
To mitigate the negative effects on the water quality in the downstream river of a projected large dam, and in particular to increase the dissolved oxygen concentration during low flow periods within the first 10 years of dam operation, an aerating weir has been designed and tested on a physical model at the Laboratory of Engineering Hydraulics (HECE ...

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Practical Engineering Application and Hydraulic Characteristics of the Flow in Stepped Spillway with Pre-aerator Slot

工程科学与技术, 2010
:The hydraulic characteristics of smooth spillway, stepped spillway and pre-aerator stepped spillway were studied. The experimental investigations showed that the pre-aerator equipment can not only keep the stepped spillway’s large energy dissipation ...

Energy Dissipation down a Stepped Spillway with Nonuniform Step Heights [PDF]

Journal of Hydraulic Engineering, 2011
Although most stepped spillway–design guidelines were developed for uniform step heights, a nonuniform stepped design might be a practical alternative in some cases. A physical study was conducted in a moderate slope-stepped chute (1V:2H) and five stepped configurations were tested for 0.7 < dc / h < 1.9.

Grounding Large Language Models for Robot Task Planning Using Closed‐Loop State Feedback

Advanced Robotics Research, EarlyView.
BrainBody‐Large Language Model (LLM) introduces a hierarchical, feedback‐driven planning framework where two LLMs coordinate high‐level reasoning and low‐level control for robotic tasks. By grounding decisions in real‐time state feedback, it reduces hallucinations and improves task reliability.
