Directional and gradient patterning from sub‐microliter colloidal droplet evaporation on inclined and stretched soft substrates

open access: yesDroplet, EarlyView.
Instead of suppressing the ubiquitous “coffee‐ring” effect, we harness it by integrating stretching, inclination, and rotation of soft substrates. This sequential control allows manipulation of global pattern symmetry and local morphology. By incorporating substrate inclination and rotation of stretched soft substrates, we create diverse patterns that ...

Quantification and description of braking during mountain biking using a novel brake power meter : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Sport & Exercise at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2017
Olympic format cross country mountain biking is both physically and technically demanding. The demands of this cycling genre are in contrast to road cycling because of the demanding off-road terrain.

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Daily Ovarian Hormone Exposure and Loss of Control Eating in Adolescent Girls: A Stage 2 Registered Report

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective This Stage 2 Registered Report examined (1) the main effects and interaction of within‐person daily associations between ovarian hormones (i.e., estrogen, progesterone) and loss of control eating (LOCE), and (2) the within‐person mediating roles of food‐related reward anticipation and response inhibition. Methods Adolescent girls (n =

Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Thermal–structural coupling analysis of brake friction pair based on the displacement gradient circulation method

open access: yesAdvances in Mechanical Engineering, 2018
In view of the braking process for the megawatt wind turbine brakes, considering the geometric and motion characteristics of brake pads and brake discs, a displacement gradient circulation method is put forward in this article, to resolve the deviation ...

An iEEG investigation on sex‐specific differences in seizure duration

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Male people with epilepsy (mPWE) are at higher risk for bilateral tonic–clonic seizures (BTCs) and sudden unexpected death in epilepsy (SUDEP) compared to female people with epilepsy (fPWE). Despite major clinical and personal implications, little is known about sex‐specific differences in seizure propagation and termination ...

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

open access: yesEnergy Science &Engineering, EarlyView.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...
