Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing

Advanced Optical Materials, EarlyView.
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Towards a semantic typology of specific determiners [PDF]

, 2017
This paper investigates properties of a class of determiners which can be loosely la- belled specific in that their distribution falls in between maximally-quantifying definite determiners and indefinites which only contribute existential quantification.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

Advanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Biocatalytic Regioselective C‐Formylation of Resorcinol Derivatives

Angewandte Chemie, EarlyView.
An acyltransferase from Chromobacterium sphagni (CsATase) was identified that catalyzes the regioselective formylation of resorcinol substrates. The formylation of substituted resorcinol derivatives yielded mono‐formylated products with up to 99% conversion and up to 74% isolated yield.

Efficiency versus Economy of Time in Multi-Unit Descending Auction: The Role of "Mari"at Flower Markets in Japan [PDF]

The auctioning rule in Japanese flower markets is a slightly modified version of that of the original Dutch flower auction. At Japanese flower markets, there is an additional stage, called "mari", where buyers who lost in the previous auction can apply ...
