Great circle links in the three-sphere

open access: yes, 2003
We investigate great circle links in the three-sphere, the class of links where each component is a great circle. Using the geometry of their complements, we classify such links up to five components. For any two-bridge knot complement,

A synergistic alliance between nematophagous fungi and organic matter against plant‐parasitic nematodes: a systematic review

open access: yesPest Management Science, EarlyView.
Certain beneficial fungi are widely used to control harmful nematodes in crops, especially when combined with organic matter. Together, they improve soil health, support plant growth, and enhance nutrient cycling. This natural partnership offers a promising, environmentally friendly approach to strengthening sustainable agriculture and reducing ...

Surface-knots in 4-space: an introduction

open access: yes, 2017
This introductory volume provides the basics of surface-knots and related topics, not only for researchers in these areas but also for graduate students and researchers who are not familiar with the field.

Recurving tropical cyclones in the western North Pacific are stronger than non‐recurving ones: Causes and implications

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the statistical characteristics of recurving tropical cyclones (TCs) over the western North Pacific (WNP). We find that recurving TCs are, on average, 38% stronger than non‐recurving TCs, owing to longer ocean exposure, fewer landfalls, and passage through warmer, more favorable thermal environments.

Balancing allocative and dynamic efficiency with redundant R&D allocation: The role of organizational proximity and centralization

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Resource‐based‐view scholars have mainly examined two resource allocation approaches for competitive advantage in multiunit firms: resource sharing and resource redeployment. These approaches emphasize allocative efficiency—the optimal allocation of resources to maximize their current value. In technology‐intensive industries,

Mapping the Conformational Landscape of DNA Minicircles Through Atomic Force Microscopy and Shape Space Analysis

open access: yesSmall, EarlyView.
An automated framework is presented for quantifying DNA conformational variability from atomic force microscopy (AFM) images. DNA backbones are reduced to spline representations and analyzed using cyclic Procrustes analysis to measure shape similarity across ensembles.

Alexander Polynomials of 3-Braid Knots

open access: yes, 2020
A knot is an embedding of a circle S1 into the three-dimensional sphere S3. A component link is an embedding of n disjoint circles Ⅱᵢⁿ =1 S1 into S3.

On the character variety of periodic knots and links

open access: yes, 2000
A link L of the 3-sphere S3 is said to be g-periodic (g≥2 an integer) if there exists an orientation preserving auto-homeomorphism h of S3 such that h(L)=L, h is of order g and the set of fixed points of h is a circle disjoint from L.

Predicting the Regioselectivity of Mechanochemical Bond Scission in Complex Molecules

open access: yesTransformative Chemistry, EarlyView.
Covalent‐bond peak force network (CBPFNet), a physics‐informed graph attention framework, predicts mechanochemical bond scission regioselectivity directly from equilibrium structures with DFT‐level accuracy. By uncovering the ‘stiffness mismatch’ mechanism, this work enables the rational design of programmable mechanical fuses for next‐generation ...
