A Geometric Characterization of Steady Laminar Flow

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Homotopy equivalent spectral transformation and Morse theory

open access: yes, 1995
this paper is to establish systematic treatment of a speech-spectrum transformation and to make the notion of " deformation of spectral-surface". For this purpose, we use the algebraic topological language mainly developed in Morse theory.

Surviving the Storm: A Qualitative Study of Caregivers' Challenges in Family‐Based Treatment for Adolescent Anorexia Nervosa

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Family‐based treatment (FBT) is the recommended first‐line outpatient treatment for adolescent anorexia nervosa (AN) in Aotearoa New Zealand (NZ), but places substantial responsibility on parents/caregivers. Although caregiver burden in FBT is increasingly recognized internationally, in‐depth qualitative work situated in the NZ ...

Synergistic Microstructure and Dielectric Engineering of Recyclable Single‐Electrode Triboelectric Nanogenerators for Sustainable Smart Homes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A recyclable triboelectric nanogenerator integrating a pseudo‐honeycomb microstructure with liquid metal doping achieves 120% higher output (122 mW m−2) and >90% retention over seven cycles, enabling self‐powered smart home functions. The performance of single‐electrode triboelectric nanogenerators (SE‐TENGs) is governed by the effective contact area ...

Towards a Morse theory on Banach spaces via ultrafunctions

open access: yesArab Journal of Mathematical Sciences, 2015
Morse Theory on Banach spaces would be a useful tool in nonlinear analysis but its development is hindered by many technical problems. In this paper we present an approach based on a new notion of generalized functions called “ultrafunctions” which ...

Enhanced Ionic Conductivity and Moisture Stability of Zr‐Based Halide Solid Electrolytes via Ta5+ Doping for All‐Solid‐State Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The high‐valence Ta5+‐substituted LZC (LZT0.3C) demonstrates high ionic conductivity, excellent compressibility, and impressive moisture stability, contributing to the long‐term cycling durability of ASSLBs. Recently developed halide solid‐state electrolytes (SSEs) have become promising alternatives for the next generation inorganic SSEs, primarily due

From Policy Presence to Policy Performance: Adaptive Improvisation and the Everyday Politics of Plastic Burning Bans in Rural Indonesia

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Open burning plastics is a major environmental health hazard in low‐ and middle‐income countries, releasing toxic pollutants and exacerbating climate change. Although Indonesia prohibits plastic burning, enforcement in rural settings remains fragile.

Disgust at Tainted Souls: Testing the Character Hypothesis of Disgust Through Descriptions of Dark Personality Traits

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Disgust is commonly reported in response to socio‐moral violations, but whether and how it differs from anger in these contexts is often debated. Preliminary evidence that disgust tracks the bad character of actors has left unanswered the question of which observable actions, other than visibly harming other people, lead to such character ...
