Impact of scissors-correction schemes on first-principles calculations of second-harmonic generation in ultraviolet nonlinear-optical crystals

In this work, we assess two widely used scissors-correction schemes for first-principles calculations of second-harmonic generation in representative borate and phosphate ultraviolet nonlinear-optical (UV-NLO) crystals, namely scheme-L [Z. H. Levine and D. C. Allan, Phys. Rev. Le...

Corrosion Behavior and Mechanism of High-Oxidation-Potential Cu-Modified V2SnC in Chloride Molten Salts

Abstract High-temperature molten salt systems are essential for energy storage and molten salt reactors, but their corrosiveness limits the durability of structural materials. MAX phases offer excellent high-temperature stability and oxidation resistance, yet the selective dissol...

A flat-band perspective on the boson peak in amorphous solids

The boson peak is a characteristic anomaly of amorphous solids broadly defined as a low-energy excess in the density of states and heat capacity compared to the textbook predictions of Debye theory. The origin of this anomaly has long been the subject of ongoing debate and remain...

Freshwater Aquaculture Dynamics in China’s Jianghan Plain Revealed by Multi-Source Satellite Imagery

The Jianghan Plain is one of the important freshwater aquaculture regions in China. Accurate information on the spatial distribution and spatiotemporal dynamics of aquaculture ponds is essential for regional ecological management. However, large-scale and accurate identification...

Collective FluidCoupling in Ultrathin Covalent OrganicFramework Membranes for High-Performance Electrokinetic Energy Harvesting

Abstract Nanofluidic membranes hold promise for hydroelectric energy harvesting, but their output power is often limited by high fluidic impedance. Here, we fabricate ultrathin covalent organic framework (COF) membranes with AA-stacked, regular nanopore arrays. These membranes ex...

A Hardware-Error-Aware Time-Domain CIM Accelerator for AdderNet with Significance-Aware Dual-Mode DTC Encoding and Shared-Clock TDC Readout

Adder neural networks remove multiplication from convolution, yet their direct L1-distance datapath still requires subtraction, absolute-value generation, and wide accumulation. We address this cost by mapping the online L1 operation to minimum selection and time-domain accumulat...

Intraseasonal variability and eddy-induced structural modulation of the North Pacific intermediate water revealed by multi-mooring observations

Abstract. The North Pacific Intermediate Water (NPIW) plays a crucial role in modulating oceanic thermohaline circulation and biogeochemical processes. However, limited continuous observations have hindered the understanding of its short-term variability and structural response t...

Trans-Percept: robust perceptive locomotion in the wild via spatiotemporal causal transformers

The integration of exteroceptive perception with proprioceptive control has revolutionized legged robot locomotion, enabling navigation through complex, non-flat terrains. Miki et al. (2022) established a seminal paradigm by fusing vision and proprioception using Recurrent Neural...

Encapsulated CsPbBr3 quantum dots with asymmetric chiral magneto-optoelectronic responses

Quantum emitters having non-trivial spin polarizations are highly demanded for chiral quantum devices and quantum photonic technologies. Here we investigate the magneto photoluminescence spectroscopy of perovskite quantum dots encapsulated in silica and report an observation of c...

siRNA-mediated mismatch repair disruption synergizes with oxaliplatin to restore immune surveillance in microsatellite-stable colorectal cancer

Proficient mismatch repair/microsatellite-stable colorectal cancer (pMMR/MSS CRC), which represents the majority of clinical cases, exhibits low tumor mutational burden and minimal responsiveness to immune checkpoint blockade. Disrupting the MMR system has been shown to resensiti...

Detection of the elusive cyclo−1,2-dihydrotetrazete (N4H2) in the gas phase

Nitrogen hydrides (NnHm) have attracted significant interest for their potential in developing high-energy-density materials. The synthesis of cyclic nitrogen hydrides is particularly challenging due to their inherently high strain energies. Here we report the preparation of the...

LXRα and PPARα Mediated Hepatic Lipid Metabolic Disruption Induced by the UV Filter EHMC in 2D and 3D HepaRG Cell Models

ABSTRACT Ethylhexyl methoxycinnamate (EHMC), an important UVB filter, is raising concerns about its potential metabolic toxicity due to widespread human exposure through dietary sources. However, little is known about the effects of EHMC on hepatic lipid metabolism and the underl...

Magnetic Field‐Modulated Ion Migration in Electrochemical Cells

Ion migration within electrochemical cells fundamentally governs interfacial reaction kinetics, charge transport, and the formation of electric double layers, thereby critically determining the overall performance of electrochemical devices. However, conventional regulation strat...

Responsive Membrane Antenna Enables Adaptive Biohybrid Interface for Photosynthesis Promotion, Stress Reporting and Modulation

ABSTRACT Biohybrids promise to endow photosynthetic organisms with new or enhanced functions, yet most operate monofunctionally, targeting either photosynthesis enhancement or stress tolerance, and cannot report environmental changes. Here, we develop an environmentally responsiv...

Need-responsive accessibility supports equitable sustainable development and reshapes migration as evolving human needs

Realizing the Sustainable Development Goals’ commitment to “leave no one behind” requires accessibility that responds to evolving human needs, yet prevailing accessibility assessments remain static and sector-specific, overlooking hierarchical need evolution and behavioral feedba...
