Low-cost method uncovers conical intersections that steer light-driven molecular reactions
Conical intersections are crucial molecular switching points in light-driven reactions, but accurately predicting them usually requires computations. A researcher from Shibaura Institute of Technology has developed a new low-cost quantum chemistry method that can simultaneously describe ground and excited molecular states while efficiently locating these elusive structures. The approach reproduces benchmark geometries with strong accuracy and enables practical simulations of photochemical...
A model for pulsation in high-speed double cone flow
arXiv:2606.01942v1 Announce Type: new Abstract: Periodic large-scale shock-wave unsteadiness over a canonical double cone, termed in literature as "pulsation," is experimentally studied at Mach 6. The general double cone geometry is defined by three non-dimensional geometric parameters: fore- and aft-cone angles ($\theta_1$ and $\theta_2$), and ratio of the conical slant lengths ($\mathit{\Lambda}$). While existing literature on pulsation offers detailed qualitative and phenomenological...
Wasserstein normalized autoencoder for anomaly detection
Announce Type: replace-cross Abstract: A novel anomaly detection algorithm is presented. The Wasserstein normalized autoencoder (WNAE) is a normalized probabilistic model that minimizes the Wasserstein distance between the learned probability distribution--a Boltzmann distribution where the energy is the reconstruction error of the autoencoder--and the distribution of the training data. This algorithm has been developed and applied to the identification of semivisible jets--conical sprays of...
Two leaks detected on International Space Station, Russian space agency says
Two leaks detected on International Space Station, Russian space agency says MOSCOW, June 5 : Russian state space agency Roscosmos said on Friday that its experts had detected two leaks aboard the International Space Station (ISS) but that there was no immediate threat to the crew. "When the transition chamber compartment of the Zvezda module was pressurised... specialists from the main operational control group for the Russian segment of the ISS detected a leak from the spacecraft,"...
Topological quantum hodographs
arXiv:2606.08528v1 Announce Type: new Abstract: In quantum mechanics, the wave function encodes all information about a particle through its probability density and phase. While stationary states are characterized by conserved quantum numbers such as energy and, in central potentials, angular momentum, non-stationary superpositions - particularly in anisotropic or time-dependent fields - generally lack equally universal descriptors of their spatiotemporal dynamics. Here we introduce quantum...
Variational low-energy subspaces for chemically accurate excited states
Announce Type: new Abstract: Accurate electronic excited states are essential for photochemistry, spectroscopy and non-adiabatic molecular dynamics, but high-level calculations often scale steeply and require prior knowledge of the target state's character or symmetry. Here we show that variational excited-state optimization can be reformulated as an iterated ground-state-like problem for a low-energy subspace of the electronic Hamiltonian. Applying this variational principle to...
Unified Regularization of 2D Singular Integrals for Axisymmetric Galerkin BEM in Eddy-Current Evaluation
arXiv:2601.19542v2 Announce Type: replace-cross Abstract: This paper presents an axisymmetric Galerkin boundary element method (BEM) for modeling eddy-current interactions between excitation coils and conductive objects. The formulation derives boundary integral equations from the Stratton-Chu representation for the azimuthal component of the vector potential in both air and conductive regions. The central contribution is a unified regularization framework for the two-dimensional (2D)...
Leak on space station triggers brief safety alert
Leak on space station triggers brief safety alert Alexander Pol Deputy Editor Astronauts working on the International Space Station briefly sheltered in a docked capsule Friday as Russian colleagues assessed leak repairs, NASA said. Five astronauts had briefly entered the docked Dragon spacecraft as a precautionary measure—the capsule functions as a lifeboat of sorts in the case an evacuation is needed. NASA gave the all clear and the astronauts were able to return to their stations.
Wind from Milky Way's supermassive black hole is finally discovered
Wind from Milky Way's supermassive black hole is finally discovered WASHINGTON, June 5 : After five decades of trying, astronomers have finally discovered the wind emanating from the supermassive black hole at the center of our Milky Way galaxy, though it turns out it is more of a gentle breeze than a hurricane. Using data from the Chile-based ALMA telescope and NASA's orbiting Chandra X-ray Observatory, the researchers viewed the cosmic neighborhood around the black hole - called...
Great mysteries of archaeology: An ancient Amazonian world revealed from the sky
Great mysteries of archaeology: An ancient Amazonian world revealed from the sky Gaby Clark Scientific Editor Andrew Zinin Lead Editor From the air, you see it only through the constant jolt, tilt, and shudder of the low-flying Cessna aircraft. The landscape of the Llanos de Moxos, northern Bolivia, appears as a disconnected patchwork of open grassland savannahs, forest islands, and lakes. It feels random, almost unreadable.
