On surfaces and Heegaard surfaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1991
Summary: This paper is concerned with the intersection of surfaces and Heegaard surfaces in closed orientable 3-manifolds \(M\). Given a Heegaard decomposition \((M, V_ 1, V_ 2)\) it will be shown that any surface (orientable or not) in \(M\) is equivalent to a surface which intersects \(V_ 1\) in discs whose total number is limited from above by some ...

Common-reflection-surface imaging of shallow and ultrashallow reflectors [PDF]

open access: yes, 2012
We analyzed the feasibility of the common-reflection-surface (CRS) stack for near-surface surveys as an alternative to the conventional common midpoint (CMP) stacking procedure.

Study on laser surface quenching structure and hardness of C45 steel

open access: yesMetalurgija, 2021
The changes of hardening depth and surface hardness of C45 steel after laser surface quenching were studied. Firstly, the Nd: YAG laser and CO2 laser were used to realize the surface quenching.

Protein Surface Interactions—Theoretical and Experimental Studies

open access: yesFrontiers in Molecular Biosciences, 2021
In this review, we briefly describe a theoretical discussion of protein folding, presenting the relative contribution of the hydrophobic effect versus the stabilization of proteins via direct surface forces that sometimes may be overlooked.

Surface impedance and optimum surface resistance of a superconductor with imperfect surface [PDF]

open access: yes, 2017
We calculate a low-frequency surface impedance of a dirty, s-wave superconductor with an imperfect surface incorporating either a thin layer with a reduced pairing constant or a thin, proximity-coupled normal layer.

The improvement of Mo/4H-SiC Schottky diodes via a P2O5 surface passivation treatment [PDF]

open access: yes, 2020
Molybdenum (Mo)/4H-silicon carbide (SiC) Schottky barrier diodes have been fabricated with a phosphorus pentoxide (P2O5) surface passivation treatment performed on the SiC surface prior to metallization. Compared to the untreated diodes, the P2O5-treated

Gold Nanoparticle Self-Aggregation on Surface with 1,6-Hexanedithiol Functionalization

open access: yesNanomaterials, 2020
Here we study the morphology and the optical properties of assemblies made of small (17 nm) gold nanoparticles (AuNPs) directly on silicon wafers coated with (3-aminopropyl)trimethoxysilane (APTES). We employed aliphatic 1,6-hexanedithiol (HDT) molecules

Interlink between solubility, structure, surface and thermodynamics in the ThO2(s, hyd)–H2O(l) system

open access: yesFrontiers in Chemistry, 2022
The impact of temperature on a freshly precipitated ThO2(am, hyd) solid phase was investigated using a combination of undersaturation solubility experiments and a multi-method approach for the characterization of the solid phase.

A multivariate semiparametric Bayesian spatial modeling framework for hurricane surface wind fields

open access: yes, 2007
Storm surge, the onshore rush of sea water caused by the high winds and low pressure associated with a hurricane, can compound the effects of inland flooding caused by rainfall, leading to loss of property and loss of life for residents of coastal areas.
