Advanced Intelligent Systems, EarlyView.A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

RETRACTED: Learner emotions and performance in hypercasual VR games with adaptive AI difficulty
British Educational Research Journal, EarlyView.Abstract Hypercasual virtual reality games (HVRGs) are widely regarded as cost‐effective tools for rapid skill acquisition, yet the mechanisms that optimise their effectiveness and user acceptance remain insufficiently explored. This mixed‐methods empirical study investigates how playful emotions, characterised by engagement, enjoyment and anxiety ...

Research priorities in emergency general surgery (EGS): a modified Delphi approach
World Journal of Emergency Surgery, 2022 Background Emergency general surgery (EGS) patients account for more than one-third of admissions to hospitals in the National Health Service (NHS) in England. The associated mortality of these patients has been quoted as approximately eight times higher

BMEMat, EarlyView.Organic field‐effect transistor (OFET)‐based biosensors are promising for wearable technology due to their flexibility and low cost, but their susceptibility to signal drift from mechanical stress and environmental factors remains a challenge. Here, we highlight a novel strategy that eliminates these drifts through a fundamental redesign of the OFET ...

Deep Underground Science and Engineering, EarlyView.Our study reveals that caving‐enhanced geothermal systems (C‐EGS) with adequately fractured reservoirs achieve optimal heat extraction by minimizing preferential flow paths, while conventional fracturing (F‐EGS) and pipe‐based (P‐EGS) systems suffer accelerated thermal drawdown.

Pro-con debate on regionalization of emergency general surgery: controversy or common sense?
Trauma Surgery & Acute Care Open, 2019 More than three million patients every year develop emergency general surgical (EGS) conditions and this number is rising. EGS diseases range from straightforward to potentially life-threatening, and if severe or complex may require extensive resources ...
