Sensory profiling of South Korean grape wines: a comparison of fast profiling methods and evaluation environments

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The South Korean wine market has rapidly expanded in recent years; however, the sensory characteristics of domestically produced red wines remain largely unexplored. This study aims to profile the sensory attributes of South Korean red wines and compare the performance of two rapid profiling methods – check‐all‐that‐apply (CATA) and

Gender, Stereotypes, and Competitive Performance Gap: An Experimental Investigation

Managerial and Decision Economics, EarlyView.
ABSTRACT This study investigates how participants in competition react to gender stereotypes in performance. We propose two novel gender‐oriented tasks: clicking as a male‐oriented task and face recall as a female‐oriented task with two treatment conditions, which can strengthen shared gender stereotypes and foster gender competition.

Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

Near Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Weeds in a changing climate: Competitors or service plants?

PLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
