Ethynyl Substituents as Rheostatic Triggers in Single‐Molecule Junctions

Small, EarlyView.
We demonstrate a method to impart rheostatic behavior by extending the core π‐system with ethynyl substituents. Compressing and relaxing single molecule junctions gave continuous changes in conductance, akin to a traditional variable resistor: a rheostat.

On Hamiltonian Cycles in Trees

, 1998
We present a simple algorithm for constructing Hamiltonian cycles on trees together with additional edges between leaves, compute the number of such additional edges required for complete k-ary trees of given depth, show this number is minimal over all ...

Reaction‐Specific Ultralow‐Pt‐Integrated CuCo Carbonate Hydroxide Nanoneedles for Durable Alkaline Seawater Electrolysis

Small, EarlyView.
Reaction‐specific ultralow‐Pt‐integrated CuCo carbonate hydroxide nanoneedles serve as optimized OER and HER electrodes, enabling durable alkaline seawater electrolysis at a low cell voltage with high H2/O2 Faradaic efficiency. ABSTRACT Developing bifunctional electrocatalysts that combine high activity, low noble‐metal usage, and durability in ...

Arc-disjoint hamiltonian paths in Cartesian products of directed cycles

Open access article. Creative Commons Attribution 4.0 International license (CC BY 4.0) appliesWe show that if C1 and C2 are directed cycles (of length at least two), then the Cartesian product C1 □ C2 has two arc-disjoint hamiltonian paths.

Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

High Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

The effect of nearby listings on house sale prices in Sydney: A spatio‐temporal regularization approach

Real Estate Economics, EarlyView.
Abstract We estimate the price impact of very nearby concurrently listed properties in the Sydney housing market and assess their competition effects. We apply a hedonic model with spatiotemporal effects regularized via a graph Laplacian prior at the month‐by‐SA2 regional level to seven SA4 subregions of metropolitan Sydney. The model structure enables

Multidimensional unipolar IRT and applications to the measurement of print exposure

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Item response theory (IRT) has been a prominent modelling framework in educational and psychological measurement. Traditional IRT models are bipolar, commonly assuming symmetric measurement link functions and symmetric trait distributions over a latent continuum unbounded at both ends. However, many measured constructs, such as print exposure,

Validation of the QOLIBRI‐KIDDY self‐rated and proxy‐rated questionnaires after paediatric traumatic brain injury

Developmental Medicine &Child Neurology, EarlyView.
This validation study examines the final versions of the QOLIBRI‐KIDDY (self‐report) and QOLIBRI‐KIDDY‐Proxy (parent‐report) questionnaires, designed to measure health‐related quality of life in children aged 6–7 following traumatic brain injury. Both versions cover six domains, demonstrate reliable psychometric properties, and give children a voice ...

Alien limit cycles in rigid unfoldings of a Hamiltonian 2-saddle cycle

, 2007
It is known that perturbations from a Hamiltonian 2-saddle cycle F can produce limit cycles that are not covered by the Abelian integral, even when the Abelian integral is generic. These limit cycles are called alien limit cycles.

Modeling Bloons Tower Defense as a temporal two‐dimensional knapsack problem with irregular shapes and side constraints: integer programming–based approaches

International Transactions in Operational Research, EarlyView.
Abstract In Tower Defense (TD) games, the objective is to defend a specific point on the game map from mobile units by constructing towers with offensive capabilities. In this work, we focus on Bloons Tower Defense (Bloons TD), one of the earliest and most prominent TD games.
