Exact two-holon wave functions in the Kuramoto-Yokoyama model

, 2006
We construct the explicit two-holon eigenstates of the SU(2) Kuramoto-Yokoyama model at the level of explicit wave functions. We derive the exact energies and obtain the individual holon momenta, which are quantized according to the half-Fermi statistics

Comparing radio-tracking and visual detection methods to quantify group size measures [PDF]

, 2015
1. Average values of animal group sizes are prone to be overestimated in traditional field studies because small groups and singletons are easier to overlook than large ones.

Strategic advertising of online news articles as an intervention to influence wildlife product consumers

Conservation Science and Practice, 2020
Changing human behavior is essential for biodiversity conservation, but robust approaches for large scale change are needed. Concepts like repeat message exposure and social reinforcement, as well as mechanisms like online news coverage and targeted ...

Outbreak of Peste des Petits Ruminants among Critically Endangered Mongolian Saiga and Other Wild Ungulates, Mongolia, 2016–2017

Emerging Infectious Diseases, 2020
The 2016–2017 introduction of peste des petits ruminants virus (PPRV) into livestock in Mongolia was followed by mass mortality of the critically endangered Mongolian saiga antelope and other rare wild ungulates.

Making vertebrate fossil radiocarbon dates more useful for global scientific research

Journal of Quaternary Science, Volume 40, Issue 8, Page 1309-1335, November 2025.
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Exact Dynamics of the SU(K) Haldane-Shastry Model

, 1999
The dynamical structure factor $S(q,\omega)$ of the SU(K) (K=2,3,4) Haldane-Shastry model is derived exactly at zero temperature for arbitrary size of the system.

Why Conservation of Australian Native Temperate Grasslands Needs to Occur at Different Scales—From Landscapes to Patches, and From Governments to Individuals

Austral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Native temperate grasslands are among the most widespread biomes in Australia, and they have been extensively modified, primarily for livestock grazing and cropping on the fertile soils ideal for agriculture. In the 1980s and 1990s, foundational work by Jamie Kirkpatrick and others brought attention to the widespread loss of these ecosystems ...

Spin Dynamics of the One-Dimensional J-J' Model and Spin-Peierls Transition in CuGeO_3

, 1997
Spin dynamics as well as static properties of the one-dimensional J-J' model (S=1/2, J>0 and 0\le \alpha=J'/J\le 0.5) are studied by the exact diagonalization and the recursion method of finite systems up to 26 sites.

A global indicator of species recovery

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Monitoring progress toward meeting global biodiversity goals involves several indicators, including, at the species level, the International Union for Conservation of Nature (IUCN) Red List Index (RLI) and the Living Planet Index (LPI). However, at present, there is no indicator specifically for tracking species recovery, despite this being ...

Electronic-Structure-Driven Magnetic Ordering in a Kondo Semiconductor CeOs2Al10 [PDF]

, 2010
We report the anisotropic changes in the electronic structure of a Kondo semiconductor CeOs$_2$Al$_{10}$ across an anomalous antiferromagnetic ordering temperature ($T_0$) of 29 K, using optical conductivity spectra.
