Stretching by outer eddies sets the turbulent breakup rate of drops and bubbles
Announce Type: replace Abstract: Fragmentation of drops and bubbles in turbulence controls interfacial area generation, mixing, and transport in environmental and engineering flows. The nonlinear coupling between interfacial and hydrodynamic stresses has long prevented predictive modeling, a challenge we here overcome by decomposing the flow into outer and inner regions. We show that breakup is driven by isolated events of extreme interfacial stretching caused by the non-local action of the...
Adaptive Metrics for Norm-Minimization-Based Outer Approximation in Convex Vector Optimization
Announce Type: replace-cross Abstract: We develop an adaptive-metric framework for norm-minimization-based outer approximation algorithms in bounded convex vector optimization. The key idea is to let the scalarization metric vary across iterations while measuring approximation error in a fixed Euclidean norm. This enables the algorithm to exploit problem geometry dynamically.
O-POPE: High-Frequency Pipelined Outer Product based GEMM acceleration with minimal buffering overhead
arXiv:2606.02333v1 Announce Type: new Abstract: General matrix multiply (GEMM) dominates both execution time and energy consumption of modern machine learning (ML) workloads, placing increasing pressure on hardware efficiency. While quantization mitigates computational and data movement costs, accuracy-sensitive tasks such as training still require higher-precision floating-point formats. Existing floating-point GEMM accelerators face trade-offs between operating frequency, arithmetic...
Beyond Outerplanarity
Announce Type: replace Abstract: We study straight-line drawings of graphs where the vertices are placed in convex position in the plane, i.e., \emph{convex drawings}. We consider two families of graph classes with convex drawings: \emph{outer $k$-planar} graphs, where each edge is crossed by at most $k$ other edges; and \emph{outer $k$-quasi-planar} graphs, where no $k$ edges can mutually cross. We show that the outer $k$-planar graphs are $\lfloor3.5\sqrt{k}\rfloor$-degenerate, and...
Asia’s ‘NewSpace’ economy is about more than just exploration
Advertisement Opinion Asia’s ‘NewSpace’ economy is about more than just exploration Outer space is growing beyond a scientific frontier to become a forum for contests over sovereignty and economic security 3-MIN READ3-MIN Listen Yogi Putranto is head of the Fisheries Intelligence and Surveillance Task Force at Cilacap Marine and Fisheries Resources Surveillance Station in Indonesia’s Ministry of Marine Affairs and Fisheries. For decades, Asia’s ambitions in outer space were closely...
Bilevel Autoresearch: Meta-Autoresearching Itself
Announce Type: replace Abstract: If autoresearch is itself a form of research, then autoresearch can be applied to research itself. We present Bilevel Autoresearch, a bilevel framework in which an outer autoresearch loop improves an inner autoresearch loop by reading its code and traces, identifying bottlenecks, and generating injectable Python search mechanisms at runtime. The inner loop optimizes task performance; the outer loop optimizes how the inner loop searches.
This star system creates a rare triple eclipse. Here's what that would look like
This star system creates a rare triple eclipse. Here's what that would look like Two stars are in a binary, which is orbited by a giant outer star. A triple star system in which the stars all eclipse one another from our vantage point is standing out as one of the best studied stellar trios; as the stars age, they could even merge.
Extreme envelope plasticity drives temperature-dependent morphogenesis in the LPS-free bacterium Sphingobium yanoikuyae
Bacterial growth patterns are generally considered to be constrained and species-specific. Here, we show that Sphingobium yanoikuyae exhibits exceptional plasticity in envelope architecture and morphogenesis driven by a glycosphingolipid (GSL)-based outer membrane and an atypical peptidoglycan structure. At 30{degrees}C, cells expand asymmetrically via a rare bipolar envelope synthesis mode, whereas growth at 37{degrees}C triggers a transition toward longitudinal elongation accompanied by...
2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints
2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints Our solar system may have hosted up to six giant planets in its first hundred million years, a new study suggests. The findings paint a more crowded picture of the early outer solar system than previously thought. Something doesn’t quite add up about the orbits of our solar system’s eight planets and their hundreds of moons, a new study hints.
A Phase Space Signature of Quantum Roaming in Chesnavich's Model
Announce Type: new Abstract: Roaming reactions occur when a molecule enters a near-dissociation region, avoids immediate separation, and later forms products by a pathway not controlled by the conventional tight transition-state bottleneck. Classical studies have shown that roaming is best understood in phase space: inner and outer transition-state structures, together with their invariant manifolds, organize trapping, return, and dissociation. The corresponding quantum question is less settled.
