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...

The translation of atomically precise metal nanoclusters into functional macroscopic devices is restricted by the difficulty of scaling manufacturing while preserving fragile quantum structures. Although two-photon lithography offers a route for micro-fabrication, the absence of...

Abstract. The interior of the Tibetan Plateau exerts a first-order influence on the Asian monsoon and regional climate, yet vertically resolved aerosol observations there are scarce, and no openly archived, multi-year, ground-based profile record has existed for this exceptionall...

Post-treatment of biogenic sulfur coating enhances autotrophic denitrification
<title>Abstract</title> Biogenic sulfur (bio-S⁰) is a promising electron donor for treating carbon-limited wastewater, yet the inherent variability of its organic coating poses an unresolved challenge for consistent denitrification performance. Here, we report that post‑treatment...

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...

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...

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...

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...

Atomic-scale evidence for continuous surface dislocations in crystalline interfaces
In interfacial dislocation theory, misfit dislocations are conventionally perceived only as discrete arrays, derivable from the quantized Frank-Bilby equation (FBE), largely because experiments and atomistic simulations can usually resolve only well-separated, discrete dislocatio...

Changes in the tropical rainfall seasonal cycle dominated by mesoscale convective systems
Global warming is reorganizing atmospheric circulation and hydroclimate, and tropical rainfall is a key manifestation of this response. Yet how these large-scale changes are translated into the tropical rainfall seasonal cycle remains uncertain because organized convection, which...

Exact Signs and Sharp Boundaries for Product-Binomial Dold Coefficients
Let X be a rational exterior space and let f: X → X. Let A = Q(f*) be the graded action on the indecomposable quotient of the positive-degree rational cohomology of X. Suppose that χ_A(t) = t^s ∏_j (t^{n_j} − a_j)^{k_j}, with a nonempty product and every a_j ≥ 3. Powering the bin...

Synergistic Dual‐Channel Charge Separation in Cr‐TiO 2‐x for Solar H 2 O 2 Synthesis
ABSTRACT Solar‐driven hydrogen peroxide (H 2 O 2 ) synthesis offers a sustainable alternative to the energy‐intensive anthraquinone process, yet its efficiency is fundamentally constrained by the inability to simultaneously harness photogenerated electrons and holes in a balanced...

Bezoutian Decoupling for Conformal Yang–Mills Multiplets in (A)dS
Metsaev's formulation of conformal Yang–Mills theory in six, eight, and ten dimensions admits a change of variables from a generic auxiliary-field presentation to a direct sum of massless and massive Stueckelberg systems. The proposed matrices in arbitrary even dimension were lef...

TogoPhosTAC as a delivery-ready platform for targeted protein dephosphorylation
Phosphorylation-targeting chimeras (PhosTACs) enable targeted protein dephosphorylation by recruiting phosphatases through induced proximity. However, the direct recruitment of phosphatase subunits or holoenzymes with small molecules remains challenging, as suitable ligands are s...

Let c be a positive integer capacity vector with total capacity C, let 1 ≤ k ≤ C − 1, and put m = min{k, C − k}. We prove both clauses of the prism-slice conjecture when m ≤ 5: the h-star polynomial is real-rooted, and for every legal unit split the unsplit polynomial weakly inte...
