The General (α,3)-Path Connectivity Indices of Polycyclic Aromatic Hydrocarbons

open access: yesDiscrete Dynamics in Nature and Society, 2018
The general (α,t)-path connectivity index of a molecular graph originates from many practical problems such as three-dimensional quantitative structure-activity (3D QSAR) and molecular chirality.

Length of a curve is quasi-convex along a Teichmuller geodesic

open access: yes, 2010
We show that for every simple closed curve \alpha, the extremal length and the hyperbolic length of \alpha are quasi-convex functions along any Teichmuller geodesic.

Dual‐Mode Film Based on Highly Scattering Nanofibers and Upcycled Chips‐Bags for Year‐Round Thermal Management

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent radiative cooling devices, adaptable to various weather conditions, have the potential for year‐round energy savings. This study introduces a sustainable dual‐mode film made from polycaprolactone nanofibers and upcycled chip bags for effective thermal management.

Extremal rays of non-integral $L$-length [PDF]

open access: yes, 2011
Let $X$ be a smooth complex projective variety and let $L$ be a line bundle on it. We describe the structure of the pre-polarized manifold $(X,L)$ for non integral values of the invariant $ _L(R):=-K_X\cdot /(L \cdot )$, where $ $ is a minimal curve of an extremal ray $R:=\mathbb R_+[ ]$ on $X$ such that $L \cdot R>0$.

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

The Final Stage of Gravitationally Collapsed Thick Matter Layers

open access: yesAdvances in High Energy Physics, 2013
In the presence of a minimal length, physical objects cannot collapse to an infinite density, singular, matter point. In this paper, we consider the possible final stage of the gravitational collapse of “thick” matter layers.

Extremal length and duality

open access: yesExpositiones Mathematicae
Classical extremal length (or conformal modulus) is a conformal invariant involving families of paths on the Riemann sphere. In ``Extremal length and functional completion'', Fuglede initiated an abstract theory of extremal length which has since been widely applied.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

open access: yesAdvanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Near-extremal Kerr-like ECO in the Kerr/CFT correspondence in higher spin perturbations

open access: yesEuropean Physical Journal C: Particles and Fields
The Kerr/CFT correspondence has been established to explore the quantum theory of gravity in the near-horizon geometry of an extreme Kerr black holes. The quantum gravitational corrections on the near-horizon region may manifest in form of a partially ...
