A NEW METHOD TO DETERMINE THE MIXING STATE OF LIGHT ABSORBING CARBONACEOUS USING THE MEASURED AEROSOL OPTICAL PROPERTIES AND NUMBER SIZE DISTRIBUTIONS

In this paper, the mixing state of light absorbing carbonaceous (LAC) was investigated with a two-parameter aerosol optical model and in situ aerosol measurements at a regional site in the North China Plain (NCP).A closure study between the hemispheric backscattering fraction (HBF) measured by an integrating nephelometer and that calculated with a

Filamentary molecular clouds are recognized as primary sites for the formation of stars.Specifically, regions characterized by the overlapping point of multiple filaments, known as hub regions, are often associated with active star formation.However, the formation mechanism of this hub structure is not well understood.Therefore, to understand the f

As techniques for fault-tolerant quantum computation keep improving, it is natural to ask: what is the fundamental lower bound on space Drying Mat overhead? In this paper, we obtain a lower bound on the space overhead required for $epsilon$-accurate implementation of a large class of operations that includes unitary operators.For the practically re

Background: Total ankle arthroplasty (TAA) is a popular and viable option for end-stage ankle arthritis.Posttraumatic arthritis is the most common etiology of ankle arthritis, which creates the additional challenge of osseus deformity.Accuracy and reproducibility in placing the implant on the mechanical axis has been shown to be paramount in all jo

The problem of uneven frost heave deformation of high-speed railway subgrade in seasonal freezing areas seriously affects the service state and service life of slab track structures and threatens the safe operation of high-speed vehicles.Based on the damage plasticity theory of concrete, in this study, an analytical model is established for CRTSIII
