Expected performance of a Laue lens based on bent crystals

open access: yes, 2012
In the context of the LAUE project devoted to build a long focal length focusing optics for soft gamma-ray astronomy (70/100 keV to $>$600 keV), we present results of simulation of a Laue lens, based on bent crystals in different assembling ...

Multiphoton‐Printed Microrobotic Arrays Powered by Discrete, Monolithically Integrated Hydrogel Actuators

open access: yesAdvanced Robotics Research, EarlyView.
Functional surfaces are investigated as a foundation for reconfigurable microscale systems with sensing and actuation capabilities. Advances in additive manufacturing enable our development of planar arrays of hybrid‐material, compliant microdevices that convert environmental stimuli into programmed motion and visual responses.

Genetic characterisation of the petal spot phenotype for Gossypium arboreum accession PI 408798

open access: yesCzech Journal of Genetics and Plant Breeding, 2020
The occurrence of floral petal spots is common among flowering plants and plays a major role in attracting pollinators. Cotton genotypes having large red petal spots are frequent in the United States Department of Agriculture, National Plant Germplasm ...

Composite Structures that Change Shape in Response to Changes in Temperature [PDF]

open access: yes, 2013
The present invention is a composite structure that changes shape as temperatures change. The composite structure utilizes a flexible substrate. The flexible substrate is static and does not change shape by itself in response to changes in temperature. A

Cardy's Formula for Certain Models of the Bond-Triangular Type

open access: yes, 2007
We introduce and study a family of 2D percolation systems which are based on the bond percolation model of the triangular lattice. The system under study has local correlations, however, bonds separated by a few lattice spacings act independently of one ...

BLADE‐ON‐PETIOLE Genes Enable Genetic Bottleneck Mitigation Through Cross‐Species Repurposing of Floral Persistence Traits

open access: yesAdvanced Science, EarlyView.
This study shows that BLADE‐ON‐PETIOLE (BOP) proteins regulate floral abscission and senescence in tomato by interacting with TFAM1 to form transcriptional condensates controlling the ARABIDOPSIS THALIANA HOMEOBOX GENE 1 (ATH1)‐mediated abscission pathway.

Sex‐Specific Regulation of Glycemic Homeostasis by Theabrownin from Pu‐erh Tea

open access: yesAdvanced Science, EarlyView.
Pu‐erh tea's key component, theabrownin (TB), lowers blood glucose in a sex‐specific manner. In females, estrogen boosts intestinal MUC2 production, which dramatically enhances TB's ability to inhibit the carbohydrate‐digesting enzyme α‐glucosidase.

A simulation program for the timing of fungicides to control Sooty Blotch in organic apple growing. First results in 2003 [PDF]

open access: yes, 2004
A simulation program for infections by Sooty Blotch was developed based on literature data and expert judgements. The value of the model as tool for timing fungicide sprays to control Sooty Blotch was tested in 2003 in two randomized plot trials, and ...

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Development status of the LAUE project

open access: yes, 2012
We present the status of LAUE, a project supported by the Italian Space Agency (ASI), and devoted to develop Laue lenses with long focal length (up to 100 meters), for hard X--/soft gamma--ray astronomy (80-600 keV).
