Fence and plough for Lapwings: Nest protection to improve nest and chick survival in Swiss farmland [PDF]

open access: yes, 2013
Switzerland had up to 1000 Lapwing pairs breeding in the 1970s. Actually, there are some 200. The crash was mainly due to a poor productivity of 0.2 to 0.4 fledglings per pair and year.

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

NESTs vs NON-NESTs in ELT

open access: yes, 2009
He will present the definition, explain the reasons why NESTs are privileged while NON-NESTs are undervalued in ELT, illustrate their advantages and disadvantages, and come up with solutions to the possible problems they are ...

Dental Microwear Texture Analysis on Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Mapping Affine Loop Nests

open access: yes, 1996
This paper deals with the problem of aligning data and computations when mapping affine loop nests onto Distributed Memory Parallel Computers (DMPCs). We formulate the problem by introducing a new graph, the access graph, to model affine communications ...

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

open access: yesAdvanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Nesting is not contracting

open access: yesJournal of High Energy Physics
A bstract The default way of proving holographic entropy inequalities is the contraction method. It divides Ryu-Takayanagi (RT) surfaces on the ‘greater than’ side of the inequality into segments, then glues the segments into candidate RT surfaces for terms on the ‘less than’

Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes

open access: yesAdvanced Optical Materials, EarlyView.
We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...
