Is faunal diversity on Maltese sandy beaches related to intensity of human use? [PDF]

open access: yes, 2004
Sandy beaches are rare in the Maltese Islands where only some 2.4% of the ca 271km coastline is sedimentary; yet such beaches are much sought after for their amenity value by tourists and locals alike.

High‐Power Terahertz Emission from Picosecond Nano‐Plasma Switching Driven by Secondary Electron Emission Avalanche

open access: yesAdvanced Science, EarlyView.
A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.

The \u27Ascent of Man\u27: Legal Systems and the Discovery of an Environmental Ethic [PDF]

open access: yes, 1998
A decade ago, firefighters in a warehouse on the Rhine in Switzerland washed chemicals, solvents, and mercury into the river, destroying all life in the river for miles, killing millions of fish, and endangering the water supplies of cities in Germany ...

A Universal Approach to Enhancing Silicon Hot‐Carrier Photodetectors for CMOS‐Compatible SWIR Imaging

open access: yesAdvanced Science, EarlyView.
Silicon hot‐carrier photodetectors offer a CMOS‐compatible pathway for SWIR detection but suffer from intrinsically low quantum efficiency. Here, we introduce a quasi‐generalized antireflection coating (QARC) that universally enhances optical absorption and quantum efficiency, enabling the first CMOS‐compatible SWIR imaging with silicon hot‐carrier ...

Bird specimen number linked with species trait and climate niche breadth

open access: yesAvian Research
Biological specimens are fundamental for taxonomy and flora/fauna research. More importantly, they also play crucial roles in recording environmental impacts on morphology and behavior, which is vital for biodiversity research and conservation.

The value of native bird conservation: A New Zealand case study [PDF]

open access: yes, 2009
During December 2007 and January 2008, telephone surveys were used to randomly sample Waikato, New Zealand residents. The purpose of the surveys was to determine whether respondents valued native bird conservation programmes in their area.

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

open access: yesAdvanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Quantum Nanomedicine and Quantum Biomaterials

open access: yesAdvanced Science, EarlyView.
In this perspective, we define quantum nanomedicine and quantum biomaterials as a paradigm that harnesses quantum effects in nanomedicine and biomaterials, including quantum superposition, quantum coherence, quantum tunneling, topological quantum effects, and spin polarization, to achieve either spatiotemporally precise modulation of physiological ...
