Habitat filtering determines spatial variation of macroinvertebrate community traits in northern headwater streams [PDF]

, 2013
Although our knowledge of the spatial distribution of stream organisms has been increasing rapidly in the last decades, there is still little consensus about trait-based variability of macroinvertebrate communities within and between catchments in near ...

Complexation‐Mediated Diffusion‐Limited Crystal Growth: A General Framework for Anisotropic Crystal Growth in Cu‐Based Perovskites

Advanced Functional Materials, EarlyView.
A Complexation‐Mediated Diffusion‐Limited Growth (CMDLG) framework is established to rationalize the anisotropic growth of lead‐free perovskites. Integrating coordination chemistry with mass transport kinetics, this study theoretically derives and experimentally validates that stable iodocuprate complexes induce a diffusion‐limited regime.

Perfect imaging in a homogeneous threedimensional region

Optics Express, 2006
We introduce a family of spherically symmetric gradient-index lenses forming a perfect (sharp) image of any point of the space in three dimensions, including the points of a homogeneous (constant refractive index) region. The only previously known example of an optical instrument with such properties is the plane mirror (or combinations thereof).

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

Advanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Consolidation, Scale Economies and Technological Change in Japanese Banking [PDF]

, 2005
The paper examines the technological structure of the Japanese banking sector before the onset of the banking crisis and structural reforms of the 90s in order to shade light on the logic of the recent trend to consolidation in the industry.

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Legislature and Constituency Size in Italian Regions: Forecasting the Effects of a Reform [PDF]

In this paper we analyze the effect of different legislature and constituency size on per capita regional expenditure in Italy. According to the theory, legislature size has an indefinite effect on government spending because logrolling and transaction ...

The expenditure impacts of individual higher education institutions (HEIS) and their students on the Welsh economy : homogeneity or heterogeneity? [PDF]

, 2010
This paper replicates the analysis of Scottish HEIs in Hermannsson et al (2010a) for the case of Wales in order to provide a self-contained analysis that is readily accessible by those whose primary concern is with the regional impacts of Welsh HEIs ...

Trends and Spatial Patterns of Drought Affected Area in Southern South America [PDF]

, 2014
Based on 56 rainfall stations, which cover the period 1961–2008, we analyzed the presence of trends in the drought-affected area over southern South America (SSA) at different time scales.
