θ-S diagrams during dilution experiments.

, 2013
θ-S plots obtained from all the potential temperature (θ) and S measurements conducted in the upper 200 m during dilution experiments in WL (top) and EL (bottom). The color intensity of the dots indicates the depth associated to each θ-S pair.

Hot deformation characteristics of a nitride strengthened martensitic heat resistant steel [PDF]

, 2014
Constitutive equations including an Arrhenius term have been applied to analyze the hot deformation behavior of a nitride-strengthened (NS) martensitic heat resistant steel in temperature range of 900–1200 °C and strain rate range of 0.001–10 /s.

Grayscale Photomasks Enable Noncontact Optical Patterning of Hydroxypropyl Cellulose Gels for Dynamic Art

Advanced Functional Materials, EarlyView.
Mask‐encoded UV exposure translates digital color information into pixel‐resolved structural‐color patterns in hydroxypropyl cellulose gels. Gaussian‐process‐guided calibration links UV processing conditions, wavelength, and mask opacity, enabling parallel fabrication of multicolor images in a single 10 s exposure.

Elastic‒plastic analysis of rock surrounding a circular roadway considering plastic hardening and dilatancy characteristics

Scientific Reports
Excavation of deep roadways induces plastic failure of the surrounding rock, resulting in roof caving and uncoordinated large deformation, which seriously threatens support safety and production efficiency. A four-stage stress‒strain model of the elastic

Bounded linear operator for some new matrix transformations

, 2012
In this paper, we define (σ, θ)-convergence and characterize (σ, θ)-conservative, (σ, θ)-regular, (σ, θ)-coercive matrices and we also determine the associated bounded linear operators for these matrix ...

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Some Properties of θ-Closure

, 1981
The concept of θ-closure was introduced by Velicko to study H-closed spaces and to generalize Taimanov's extension theorem [11], [12]. More recently, this notion has been used by Dickman and Porter [1] to characterize those Hausdorff spaces in which the ...
