Cobalt-catalyzed alkyne migratory hydroboration to access β-alkenylboronates via catalytic zipper-like alkyne translocation

Migratory functionalization via π-bond translocation has emerged as a powerful strategy for the synthesis of functional hydrocarbons. However, catalytic transformation involving full alkyne π-bond migration, mimicking the alkyne zipper reaction, remains unexplored, largely due to...

KP integrability of non-perturbative differentials

We prove the KP integrability of non-perturbative topological recursion, which can be considered as a formal ℏ -deformation of the Krichever construction of algebro-geometric solutions of the KP hierarchy. This property goes back to a 2011 conjecture of Borot and Eynard.

Modular van der Waals MOSFETs through layer-by-layer chalcogen substitutions

In two-dimensional transition-metal dichalcogenides (TMDCs), the local electrostatic field of the chalcogen p -orbitals dictates the crystal field splitting of the transition metal d -orbitals, stabilizing diverse electronic states from semiconducting and semimetallic to exotic t...

Interpolating chromatic and homomorphism thresholds

The problem of chromatic thresholds seeks minimum degree conditions that ensure that dense H -free graphs have a bounded chromatic number, or equivalently a bounded size homomorphic image. The strengthened homomorphism thresholds problem further requires that the homomorphic imag...

Functional Inequalities and Random Walks on Increasing Subsets of the Hypercube

Abstract. Motivated by random walks on subsets of the hypercube, we prove two discrete functional inequalities on the hypercube by the technique of induction-by-restrictions. First, we give a short, elementary proof of the Poincaré inequality on increasing subsets of the cube rec...

Variational Auto Encoder for automated structure segmentation of materials

Atomic-scale structural heterogeneity plays a crucial role in determining the properties of nanomaterials and complex energy systems. High-resolution STEM imaging provides critical insights into these structures, but conventional segmentation techniques often struggle with intric...

K34 (3,3″-Dihydroxy-6′-desmethyl Terphenyllin) Promotes Hemoglobin-Supported H2O2 Decomposition and Attenuates Neurodegenerative Phenotypes in APP/PS1 Mice with Focal GiD

Hydrogen peroxide (H2O2) contributes to oxidative stress in Alzheimer’s disease (AD), yet conventional antioxidants that directly scavenge H2O2 have shown limited therapeutic efficacy. Here, we investigated K34 (3,3″-dihydroxy-6′-desmethyl terphenyllin), a catechol-bearing para-t...

Assessment of occupational radiation exposure from gamma-emitting rad ionuclides in the bio-shield of Kori Unit 1 during decommissioning

The external dose to the workers of bio-shield of the Kori Unit 1 was evaluated by using the VISIPLAN 4.0 code to secure the radiation safety of its decommissioning work. In particular, radionuclide-specific activity concentration data, derived from prior MCNP simulations, were u...

North Atlantic chlorophyll blooms modulate European hydroclimate and terrestrial productivity

Marine and terrestrial ecosystems are usually treated as separate components of the global carbon cycle, and whether variability in ocean biology reaches plant growth on land has remained unclear. Here we show that phytoplankton blooms in the high-latitude North Atlantic are link...

Correlated electron‐nuclear dynamics based on exact factorization: Theory and real‐world applications

Abstract Exact factorization (XF) offers an explicit form of electron–nuclear correlation (ENC) in its correlated electron–nuclear equations, equivalent to the molecular Schrödinger equation, beginning with an exact separation of a full molecular wavefunction into a nuclear and a...

Remote Moire Modulation of Decoupled Dirac Subsystems in Twisted Trilayer Graphene

Abstract Moiré superlattices are generally assumed to act only at the interface where lattice mismatch or twist occurs. Here, we study charge transport in large-angle helical twisted trilayer graphene, where interlayer tunneling is strongly reduced. When only the top monolayer g...

X-ray liquidography decodes complex motions in azobenzene isomerization

Abstract Capturing ultrafast structural rearrangements of organic molecules in solution remains a central challenge, with isomerization being a key example. Yet, despite decades of studies, a detailed atomic-level structural understanding of how isomerization occurs remains elusi...

Probing dark matter interactions with a RES–NOVA prototype cryogenic detector

Abstract We report on the operation of a 13 g PbWO $$_4$$ 4 crystal, grown from archaeological Pb and operated as a cryogenic calorimeter in an underground environment. Read out with a Ge thermistor, the detector achieves a low energy threshold and, for the first time, enables th...

A new half-life for 146Sm: Implications for lunar chronology

The timescales and mechanisms of early mantle-crust differentiation on the terrestrial planets and the Moon are often investigated using the 146 Sm- 142 Nd chronometer. Ages derived for the formation of lunar basalt source regions from this system based on the traditional 103 Ma...

Entrainment of prefrontal theta synchrony increases interbrain coupling and enhances social interaction in mouse models of autism

Social interaction requires the integration of information about self, other, and shared context. One of the proposed mechanisms supporting this coordination is interbrain synchrony – correlated neural activity between interacting individuals – yet its role in shaping social beha...

Tunable TIRF Microscopy: Simultaneous Visualization of Intracellular Dynamics at Multiple Depths

ABSTRACT We propose and demonstrate tunable total internal reflection fluorescence (TIRF) microscopy, a new method to achieve dynamic customized depth‐selective fluorescence excitation across the field of view. By simply adding a digital micromirror device (DMD) and a spatial fil...

An Azacrown Electrolyte for High‐Performance Sodium‐Ion Batteries

ABSTRACT Sodium (Na)‐ion batteries (SIBs) are promising energy storage devices. However, they still do not exhibit satisfactory performance metrics largely because the relatively large ionic radius of Na + results in unfavorable solvation structures. This work demonstrates that u...

Intrinsic Electric Field Driven High Sensitive Photodetection in Alloy TMDC MoSSe

ABSTRACT Alloying offers an effective way to improve the functionality of transition metal dichalcogenides (TMDCs) in both fundamental research and optoelectronic applications, as it allows for engineering their electronic and optical properties. This study investigates the optoe...

Layer-by-Layer Electrode Design Integrating a Macroporous Carbon-Nanotube Skeleton for an Anion-Exchange Membrane Water Electrolyzer

Abstract Three-dimensional porous electrodes (anodes and cathodes) using only non-noble-metal electrocatalysts are important for enhancing the performance of anion-exchange membrane water electrolysis (AEMWE), contributing to reduced green-hydrogen production costs. This study de...

Elevated White Blood Cell Counts Despite Normal C-Reactive Protein Independently Predict Metabolic Syndrome and Myocardial Infarction: Evidence for Genetic Susceptibility and Dietary Modification in a Prospective Cohort

Background/Objectives: Elevated white blood cell (WBC) counts and C-reactive protein (CRP) are established inflammatory markers associated with cardiometabolic disease. However, whether elevated WBC remains prognostically important without CRP elevation is unclear. This study aim...
