Relationship among land surface temperature and LUCC, NDVI in typical karst area

Scientific Reports, 2018
Land surface temperature (LST) can reflect the land surface water-heat exchange process comprehensively, which is considerably significant to the study of environmental change.

Textile Encoding Inspired by Langer Lines via Elastically Graded Embroidered Tessellations

Advanced Materials, EarlyView.
A standard embroidery machine can encode skin‐like directional mechanics into stretchable fabrics that, when worn, augment the wearer's skin. Zigzag stitch patterns, inspired by skin collagen structure, pack extra slack in threads that, when tessellated, mimic Langer lines.

A Low‐Cost Curvature Detection Method for an Untethered Biped Pipeline Climbing Robot with Energy‐Efficient Strategy

Advanced Robotics Research, EarlyView.
A low‐cost pipeline curvature detection method has been proposed for an untethered biped pipeline surface climbing robot (BPCR) system with a five‐degree‐of freedom structure. The BPCR features adaptive vacuum suction cups equipped with multiple laser sensors on the suction modules to detect the curvature of various surfaces.

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

Advanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Memory Manufacture Under Microgravity (MMuM): In‐Space Manufactured ZnO‐Based Resistive Random Access Memory for Emerging Computing Application

Advanced Electronic Materials, EarlyView.
This paper presented ZnO‐based crossbar RRAMs by electrohydrodynamic (EHD) printing technology under in‐space manufacture environment as microgravity (µG). The crossbar structures of Ag/ZnO/Ag are fabricated under earth with in‐space microgravity. With the microgravity effect, a significant electroforming forming voltage reduced 89.3% as a storage ...

The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee

Agribusiness, EarlyView.
ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

American Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

Flavonoid Profile, Biological Potentials, and In Silico Approaches of Methanol Extracts on AChE: Amaranthus retroflexus L.

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study investigated the flavonoid compounds and their biological activities in methanol extracts obtained from root, stem, leaf, and flower parts of Amaranthus retroflexus L. Flavonoids in the extracts were characterized for the first time by liquid chromatography–highresolution mass spectrometry (LC–HRMS), and a total of eight flavonoid ...
