'Yang Jiang' 'Kangyao Wen' 'Fangzhou Du' 'Yi Zhang' 'Chenkai Deng' 'Zilong Xiong' 'Haozhe Yu' 'Qing Wang' 'Hongyu Yu' 'Filippo Giannazzo'] This study optimizes the CuOx/Ga2O3 heterojunction diodes (HJDs) by tailoring the structural parameters of CuOx layers. The hole concentration in the sputtered CuOx was precisely…

Traditional broadband UV optical designs often have complex structural problems and cannot meet the current requirements of light and miniaturization. In this study, we first design the substrate material of double-layer diffractive optical elements (DOEs) in the 0.23-0.8 μm band, optimize the diffraction efficiency…

'Ameer Hamza Khan' 'Shuai Li' 'Danish Hussain'] In recent years, twin stacker crane units have been increasingly integrated into large automated storage and retrieval systems (AS/RSs) in shipyards to enhance operational efficiency. These common rail units often encounter conflicts, and the additional time costs…

'Baosheng Du' 'Yongzan Zheng' 'Jifei Ye' 'Chenglin Li' 'Florenta Costache' 'Stéphane Valette' 'Jörn Bonse'] In the field of laser ablation micro-propulsion, the property of double-layer tape has significant impact on the propulsion performance. In this paper, low temperature plasma was used to treat the surface of…

'Christoph G. Salzmann' 'Angelos Michaelides'] The formation of monolayer and multilayer ice with a square lattice structure has recently been reported on the basis of transmission electron microscopy experiments, renewing interest in confined two dimensional ice. Here we report a systematic density functional theory…

A double-layer lens consists of a first gradient-index/geodesic profile in an upper waveguide, partially surrounded by a mirror that reflects the wave into a lower guide where there is a second profile. Here, we derive a new family of rotational-symmetric inhomogeneous index profiles and equivalent geodesic lens shapes…

The double layer at metal-aqueous interfaces in electrocatalytic systems has two features that are inadequately described by classical double layer models, namely, metal-water chemical interactions and chemisorption of partially charged adsorbates. A modified model is developed herein to encompass these two features.…

The double layer on transition metals features chemical metal-water interactions and chemisorption of partially charged adsorbates, which have not been adequately described in previous double layer models developed for mercury-like metals. A new model with an improved description of both is developed herein. The first…

This paper investigates the double descent phenomenon in two-layer neural networks, focusing on the role of L1 regularization and representation dimensions. It explores an alternative double descent phenomenon, named 'sparse double descent'. The study emphasizes the complex relationship between model complexity…

The phenomenon of model-wise double descent, where the test error peaks and then reduces as the model size increases, is an interesting topic that has attracted the attention of researchers due to the striking observed gap between theory and practice [2]. Additionally, while double descent has been observed in various…

Double emulsion droplets (DEs) are water/oil/water droplets that can be sorted via Fluorescence-Activated Cell Sorting (FACS), allowing for new opportunities in high-throughput cellular analysis, enzymatic screening, and synthetic biology. These applications require stable, uniform droplets with predictable…

This paper presents a canonical d.c. (difference of canonical and convex functions) programming problem, which can be used to model general global optimization problems in complex systems. It shows that by using the canonical duality theory, a large class of nonconvex minimization problems can be equivalently converted…

'Jinkyu Yang'] Automated Fiber Placement (AFP) technology provides a great ability to efficiently produce large carbon fiber reinforced composite structures with complex surfaces. AFP has a wide range of tow placement angles, and the users can design layup angles so that they can tailor the performance of the…

'Martin Hammerschmidt' 'Sven Burger' 'Carsten Rockstuhl'] Numerical optimization is an important tool in the field of computational physics in general and in nanooptics in specific. It has attracted attention with the increase in complexity of structures that can be realized with nowadays nano-fabrication technologies…

“How thick is your light sheet?” is a question that has been asked frequently after talks showing impressive renderings of 3D data acquired by a light-sheet microscope. This question is motivated by the fact that most of the time the thickness of the light-sheet is uniquely associated to the axial resolution of the…

Double water-in-oil-in-water (W/O/W) emulsions are aqueous droplet(s) embedded within oil droplets dispersed in a continuous water phase. They are exploited for many applications from cosmetic to food science since both hydrosoluble and liposoluble cargos can be encapsulated within. They are generally prepared using a…

The combined density functional theory and multi-reference configuration interaction (DFT/MRCI) method is a semi-empirical electronic structure approach that is both computationally efficient and of predictive accuracy for the calculation of electronic excited states and simulation of electronic spectroscopies.…

The production of water-in-water emulsion droplets, the coalescence of which is prevented by adding oil-in-water micrometric droplets is reported. Hexadecane (O) and cetyl trimethyl ammonium bromide (CTAB) were added to a W/W emulsion made of dextran (Dex)-enriched droplets in a Polyethyleglycol (PEG)-enriched…
