Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Subcritical convection of liquid metals in a rotating sphere using a quasi-geostrophic model

, 2016
We study nonlinear convection in a rapidly rotating sphere with internal heating for values of the Prandtl number relevant for liquid metals ($Pr\in[10^{-2},10^{-1}]$).

Effects of Long-Range Nonlinear Interactions in Double-Well Potentials [PDF]

, 2010
We consider the interplay of linear double-well-potential (DWP) structures and nonlinear longrange interactions of different types, motivated by applications to nonlinear optics and matter waves.

Emergence Profile Angle Matters—Restoring Peri‐Implant Health by Adjusting Prosthetics—A Narrative Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To review the biological and clinical relevance of prosthetic design, specifically the emergence profile and restorative angle in influencing peri‐implant tissue health, and to illustrate how biologically driven prosthetic modifications can resolve inflammation and support peri‐implant stability.

Natural convection of viscoplastic fluids in a triangular enclosure

Applications in Engineering Science
This study extends the analysis of natural convection in a viscoplastic fluid to flow within a triangular enclosure. The finite-element approach provided a numerical solution to the continuity, momentum, and energy equations. The governing parameters for

Review of Zeeman Effect Observations of Regions of Star Formation

Frontiers in Astronomy and Space Sciences, 2019
The Zeeman effect is the only observational technique available to measure directly the strength of magnetic fields in regions of star formation. This chapter reviews the physics of the Zeeman effect and its practical use in both extended gas and in ...

Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

Journal of Prosthodontics, EarlyView.
Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.

On the solutions of the one dimensional Ginzburg-Landau equations for superconductivity

, 1999
This paper gives a complete description of the solutions of the one dimensional Ginzburg-Landau equations which model superconductivity phenomena in infinite slabs. We investigate this problem over the entire range of physically important parameters: $a$

Criticality and convergence in Newtonian collapse [PDF]

, 2002
We study through numerical simulation the spherical collapse of isothermal gas in Newtonian gravity. We observe a critical behavior which occurs at the threshold of gravitational instability leading to core formation. For a given initial density profile,

The Core‐Periphery Model Under Additively Separable Preferences

Journal of Regional Science, Volume 65, Issue 2, Page 378-402, March 2025.
ABSTRACT This paper reexamines Krugman's core‐periphery model by substituting his constant elasticity of substitution (CES) utility with a general additively separable utility that comprehensively captures the pro‐competitive effect while preserving the income effect.
