Conductance distributions in disordered quantum spin-Hall systems

open access: yes, 2010
We study numerically the charge conductance distributions of disordered quantum spin-Hall (QSH) systems using a quantum network model. We have found that the conductance distribution at the metal-QSH insulator transition is clearly different from that at

Non‐Native Bird Populations Respond Differently to Their Environment and Exhibit Shifts in Ecological Niche Limits Across Continents

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim The degree to which species' niches remain stable over space and time–the niche conservatism hypothesis–is critical for predicting species' responses to environmental change. Tests of this hypothesis typically focus on changes in niche centroids and boundaries.

Exploring High‐Charge‐Density Polyelectrolytes as Membrane Component for Solid Contact Ion‐Selective Electrodes

open access: yesElectroanalysis, Volume 37, Issue 9, September 2025.
Real‐time potential recording of two potassium‐selective electrodes, each with a different ion‐selective membrane (ISM): a traditional four‐component ISM (light green, bottom) and a new, three‐component one where the matrix polymer and lipophilic salt are replaced by a high‐charge‐density polyelectrolyte (PE) ISM (dark green, top). The incorporation of

Promotor rasta cink-bacitracin

open access: yesVeterinarska stanica, 2014
Cink-bacitracin je smjesa polipeptida visoke molekulske mase (bacitracin A, B i C te 13 manjih komponenti). Prvi put je opisan 1945. godine kao proizvod Bacillus sp. (Bacillus licheniformis), koji kontaminira rane. Najstabilniji je u obliku cinkove soli te se koristi kao promotor rasta u preparatima u humanoj i veterinarskoj medicini.

Cardiorespiratory Fitness and Neurophysiological Indices of Working Memory Maintenance in Young Adults

open access: yesPsychophysiology, Volume 62, Issue 2, February 2025.
Impact Statement This study reveals that cardiorespiratory fitness enhances working memory maintenance under high cognitive load by promoting proactive cognitive control strategies in young adults. These findings provide an indication that improving fitness can strengthen cognitive resilience in demanding situations, relevant to academic and ...

Comparison of the Bond Strengths of Zinc Phosphate, Glass-Ionomer, and Compomere Cement for Dowel Cementation [PDF]

open access: yes, 2002
Unatoč dosad mnogim provedenim istraživanjima, ne postoji jedinstvena ocjena koji je cement najbolji za cementiranje konfekcijskih kolčića. Svrha rada bila je ispitati i usporediti retenciju konfekcijskih kolčića cementiranih s trima različitim vrstama ...

A Trophic and Non‐Trophic Seasonal Interaction Network Reveals Potential Management Units and Functionally Important Species

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim Understanding the organisation of the wide variety of ecological interactions is crucial to advancing our understanding and management of real ecosystems. We aimed to compile a ‘complete’ network of tetrapod trophic and non‐trophic interactions for the entire North American boreal forest biome that could be analysed to gain insights into ...
