An experimental and numerical investigation of a turbulent airfoil wake in a 90° curved duct
, 2002 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A wake behind solid bodies subjected to extra rates of strain due to streamwise curvature and pressure gradient occurs in numerous engineering applications.

A physics-based model for wind turbine wake expansion in the atmospheric boundary layer
Analytical wind turbine wake models are widely used to predict the wake velocity deficit. In these models, the wake growth rate is a key parameter specified mainly with empirical formulations.

Advanced Science, EarlyView.Biological rhythms coordinate physiology, from genes to behavior. Study of circadian rhythms in brain tissue is constrained by limited throughput and spatial and temporal information quality. A new platform for high‐throughput, long‐term multiplexed fluorescent live imaging of circadian rhythms in brain slices is introduced.

Dynamic wake meandering modeling [PDF]
, 2007 We present a consistent, physically based theory for the wake meandering phenomenon, which we consider of crucial importance for the overall description of wind turbine loadings in wind farms. In its present version the model is confined to single wake situations.

A model of the ion wake of Mars
Geophysical Research Letters, 1990 Observations from the PHOBOS spacecraft suggest that, for the most part, the Martian magnetotail is induced instead of intrinsic. In this paper, test particle techniques are used to detemine how the associated ion wake might appear to detectors behind Mars if it is produced primarily by planetary ions picked up by the solar wind in the dayside ...

Fluoroacetonitrile‑Based Gel Polymer Electrolytes for Fast‑Charging Lithium Metal Batteries
Advanced Science, EarlyView.A gel polymer electrolyte using fluoroacetonitrile (FAN) as the solvent and fluoroethylene carbonate (FEC) and LiNO3 as additives is proposed for fast‐charging lithium metal batteries. These additives are preferentially reduced on the lithium metal anode surface to form a stable SEI layer, effectively suppressing the reductive decomposition of FAN.

Advanced Science, EarlyView.Brown adipocyte sheets are engineered to protect the heart against myocardial ischemia–reperfusion injury by restraining ferroptosis. Upon transplantation onto the cardiac surface, they improve cardiac function, limit infarction and fibrosis, and enhance angiogenesis.

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation
Advanced Science, EarlyView.Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium
Advanced Science, EarlyView.A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and
