Improved projective covering method for fractal dimensions of rock discontinuities based on stochastic analysis

open access: yes工程科学学报, 2018
The strength, deformability, and flow properties of rock discontinuities are strongly affected by the surface characteristics. Therefore, a quantitative description of the topography of the discontinuities is very important.

Solar parity issue with flux-transport dynamo

open access: yes, 2010
We investigated the dependence of the solar magnetic parity between the hemispheres on two important parameters, the turbulent diffusivity and the meridional flow, by means of axisymmetric kinematic dynamo simulations based on the flux-transport dynamo ...

Tailoring Thermophysical Properties and Multiscale Machine Learning Modeling of 2D Nanomaterial‐Infused Beeswax as a Green NePCM for Sustainable Thermal Management Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study develops eco‐friendly two‐dimensional nanoparticle‐enhanced phase change materials (2D NePCMs) using biodegradable beeswax infused with rGO, GO, and MXene nanoparticles. Experimental results demonstrated up to 21.9% enhancement in thermal conductivity with minimal latent heat loss, while machine learning models achieved >95% predictive ...

Evaluating predictive values of umbilical cord arterial lactate for adverse newborn outcomes among term‐births in northern Uganda: A cross sectional analytical study

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 408-420, April 2025.
Abstract Objective Birth asphyxia is one of the leading causes of death for neonates worldwide. Lack of an objective cost effective test to predict poor newborn outcomes at birth affects the ability to respond appropriately. This study determined predictive values of umbilical cord arterial lactate in relation to adverse neonatal outcomes. Methods This

Yoked surface codes

open access: yesNature Communications
One of the biggest obstacles to building a large scale quantum computer is the high qubit cost of protecting quantum information. For two-dimensional architectures, the surface code has long been the leading candidate quantum memory, but can require ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

open access: yesLaser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Non-Direct Encoding Method Based on Cellular Automata to Design Neural Network Architectures [PDF]

open access: yes, 2005
Architecture design is a fundamental step in the successful application of Feed forward Neural Networks. In most cases a large number of neural networks architectures suitable to solve a problem exist and the architecture design is, unfortunately, still ...

Relations between three-point configuration space shear and convergence statistics

open access: yes, 2011
With the growing interest in and ability of using weak lensing studies to probe the non-Gaussian properties of the matter density field, there is an increasing need for the study of suitable statistical measures, e.g. shear three-point statistics.

High‐Throughput Screening of Rare‐Earth Compounds as Promising Deep‐Ultraviolet Light Emitters

open access: yesMaterials Genome Engineering Advances, EarlyView.
A high‐throughput screening of rare‐earth compounds is conducted to identify promising deep‐ultraviolet (DUV) light emitters. With carefully designed selection criteria, Na3LuBr6 and Na3TmBr6 are identified as promising candidates. This study accelerates the development of DUV light emitters.
