Abstract:
... Knowledge of surface roughness with the consequent presence of crust in the soil is important information for the rational management of environmental resources. Soil surface roughness can be determined by contact and noncontact methods. Contact methods have lower values and precision than noncontact methods. Therefore, the objective of this study was to develop low-cost, portable and robust optic ...
... The current color difference online detection algorithm has poor real-time performance. The noise affects color difference monitoring and sampling detection results are different from online detection. Therefore, a color difference online detection algorithm is studied. Firstly, the Flat Field and Perfect Reflector Method (PRM) are used to correct the color illumination uniformity of warp knitted ...
... Deep learning (DL) has achieved significant attention in the field of infrared (IR) and visible (VI) image fusion, and several attempts have been made to enhance the quality of the final fused image. It produces better results than conventional methods; however, the captured image cannot acquire useful information due to environments with poor lighting, fog, dense smoke, haze, and the noise genera ...
... Owing to the instability of organic materials, an inorganic perovskite solar cell (PSC) attracts much attention in recent years. However, the instability of phase and overmuch traps lead to the inferior performance of inorganic perovskite solar cell, a high performance inorganic PSC is desirable. The element of cerium possesses a suitable chemical and physcial properties to substitute lead. We uti ...
... Using one-night sleep recordings from 852 subjects all living in Uppsala, Sweden, the present study represents one of the largest polysomnography investigations into the association of the 29.53-day long lunar cycle with sleep among men and women and across a wide age range (22–81 years). Following the day after the new moon until the day of the full moon (also named the waxing period), the moon's ...
... An accurate ego-motion estimation solution is vital for autonomous vehicles. LiDAR is widely adopted in self-driving systems to obtain depth information directly and eliminate the influence of changing illumination in the environment. In LiDAR odometry, the lack of descriptions of feature points as well as the failure of the assumption of uniform motion may cause mismatches or dilution of precisio ...

Abstract:
... Doping Mn²⁺ into CsPbCl₃ nanocrystals (NCs) yields strong orange emission, while the related emission in Mn²⁺ doped CsPbBr₃ NCs is impaired seriously. This is mainly ascribed to back energy transfer from the Mn²⁺ dopant to the host. Doping Mn²⁺ into perovskites with multiple-quantum-well (MQW) structures may address this issue, where the energy funnels ensure a rapid energy transfer process, and t ...

Abstract:
... Low-temperature electronic devices are indispensable for quantum computing and space exploration applications. However, developing memory devices that are an integral part of the control circuits of low-temperature electronic devices is highly challenging. The electrical conductivity of semiconducting materials drops at low temperatures, leading to large variations in SET/RESET voltages. A strateg ...

Abstract:
... Organic compounds that can be triggered using light to release CO in biological environments are of significant current interest to probe the role of CO in biology and as potential therapeutics. We recently reported that a 3-hydroxybenzo[g]quinolone (5) can be used as a CO delivery molecule to produce anticancer and potent anti-inflammatory effects. Herein we report mechanistic studies of the visi ...

Abstract:
... Platelet granules contain a diverse group of proteins. Upon activation and during storage, platelets release a number of proteins into the circulation or supernatant of stored platelet concentrate (PC). The aim of this work was to investigate the effect of pathogen inactivation (PI) on a selection of proteins released in stored platelets. Materials and Methods: PCs in platelet additive solution (P ...

... UV-to-red downshifting phosphors such as BaAl₂O₄:Eu³⁺ find broad range of application in sensors, displays, and in solid-state lighting, yet new synthetic routes to improve their luminescence are envisaged. In this regard, herein, it is introduced two new methods to synthesize this environmentally friendly BaAl₂O₄:Eu³⁺, by an adapted sol–gel route and a modified Pechini synthesis. Additionally, a ...

The synthesis of spectral remote sensing images of the Earth’s background is affected by various factors such as the atmosphere, illumination and terrain, which makes it difficult to simulate random disturbance and real textures. Based on the shared latent domain hypothesis and generation adversarial network, this paper proposes the SDTGAN method to mine the correlation between the spectrum and di ...

... The benefits of excess PbI₂ on perovskite crystal nucleation and growth are countered by the photoinstability of interfacial PbI₂ in perovskite solar cells (PSCs). Here we report a simple chemical polishing strategy to rip PbI₂ crystals off the perovskite surface to decouple these two opposing effects. The chemical polishing results in a favorable perovskite surface exhibiting enhanced luminescenc ...
