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...

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...

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...

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...

Mechanism and plasticity of primitive pyroptosis

Pyroptosis is a proinflammatory form of regulated cell death across the tree of life. The gasdermin (GSDM) protein family functions as an evolutionarily conserved executioner of pyroptotic cell death by forming membrane pores. As the canonical activation mechanism, proteolytic cl...

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...

How does advertising goal framing impact green hotel consumption intentions? The moderating role of nature connectedness

Promoting green hotel consumption is a key element in the green transformation and upgrading of the tourism industry. Goal framing serves as a common method of information presentation to encourage consumer behavior. However, few studies have examined how advertising goal framing...

Atmospheric Blocking Pattern as the Primary Driver of Subseasonal Greenland Ice Sheet Summer Melt Variability

ABSTRACT The anomalous summer melting of the Greenland Ice Sheet (GrIS) is one of the key signals of ongoing climate system changes. The complex spatiotemporal characteristics of GrIS and its impacts on global sea‐level rise have attracted increasing attention. Although previous...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Prism-Slice h-star Polynomials: Interlacing Through Reduced Level Five and a Level-Six Counterexample

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...

Changes of Precipitation Extremes and Persistence Over the Tibetan Plateau Projected by a Convection‐Permitting Model

Abstract Extreme precipitation has increased over many regions in recent decades, but the simulation and projection remain particularly challenging over complex terrains, such as the Tibetan Plateau (TP). Here, we investigate the future changes in precipitation extremes and persi...

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...

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...

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...

GPU-accelerated finite-element method for the three-dimensional unstructured mesh atmospheric dynamic framework

Abstract. The three-dimensional unstructured-mesh finite-element atmospheric dynamical framework is gaining significance owing to its flexibility in representing complex topography and capability for multi-scale simulations in high resolutions. However, this framework has substan...

Robust and Efficient Dual-Strategy Switch Migration for Failure Recovery in Software-Defined Satellite Networks

Software-defined satellite networks (SDSNs) enhance resource utilization and flexibility in space-based networks by leveraging a global view and programmability. A highly reliable control plane is essential to sustain network operations. However, the highly dynamic topology and p...

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...
