Analytic Properties and Covariance Functions of a New Class of Generalized Gibbs Random Fields [PDF]

, 2006
Spartan Spatial Random Fields (SSRFs) are generalized Gibbs random fields, equipped with a coarse-graining kernel that acts as a low-pass filter for the fluctuations. SSRFs are defined by means of physically motivated spatial interactions and a small set

CT-derived sarcopenia should not preclude surgical stabilization of traumatic rib fractures

European Radiology Experimental, 2021
Background Rib fractures are associated with considerable morbidity and mortality. Surgical stabilization of rib fractures (SSRF) can be performed to mitigate complications. Sarcopenia is in general known to be associated with poor clinical outcomes.

Upcycling Spent Lithium Iron Phosphate Battery Into Fe-CN₃P Single Atom Catalyst for Environmental Remediation. [PDF]

Angew Chem Int Ed Engl
Electrochemical (EC) advanced oxidation enables near‐complete lithium and iron recovery from spent lithium iron phosphate batteries, while simultaneously transforming leach residues into a high‐performance P, N‐doped single‐atom Fe catalyst. The reconstructed Fe–CN3P catalyst exhibits exceptional peroxymonosulfate (PMS) activation and rapid bisphenol A

Time to surgical stabilization of rib fractures: does it impact outcomes?

Trauma Surgery & Acute Care Open
Objectives Rib fractures are common, morbid, and potentially lethal. Intuitively, if interventions to mitigate downstream effects of rib fractures can be implemented early, likelihood of developing these complications should be reduced.

Spatial Random Field Models Inspired from Statistical Physics with Applications in the Geosciences

, 2006
The spatial structure of fluctuations in spatially inhomogeneous processes can be modeled in terms of Gibbs random fields. A local low energy estimator (LLEE) is proposed for the interpolation (prediction) of such processes at points where observations ...

Redox‐Mediated Stabilization of the Hole Transport Layer and Buried Interface Toward Stable Perovskite Solar Cells

Angewandte Chemie, EarlyView.
A facile and effective strategy, that is, synergistic regulation of the NiOx/SAM buried interface via cesium oxalate (CsOA) modification, is developed. The CsOA treatment suppresses detrimental Ni4+ formation, promotes uniform SAM assembly, and aligns the energy levels at the hole‐transport layer/perovskite interface, enabling improved film ...

Thoracoscopic-assisted rib plating (TARP): initial single-center case series, including TARP in the super elderly, technical lessons learned, and proposed expanded indications

Trauma Surgery & Acute Care Open, 2022
Objectives The application of surgical stabilization of rib fractures (SSRF) remains inconsistent due to evolving indications and perceived associated morbidity.

Radial Covariance Functions Motivated by Spatial Random Field Models with Local Interactions

, 2014
We derive explicit expressions for a family of radially symmetric, non-differentiable, Spartan covariance functions in $\mathbb{R}^2$ that involve the modified Bessel function of the second kind. In addition to the characteristic length and the amplitude

Quantum description of free electron laser radiation and nonlinear amplitude equations

AIP Advances, 2023
A relativistic quantum mechanical model to describe the quantum free electron laser dynamics has been developed. Neglecting the spin of electrons in the impacting beam, this model is based on the Klein–Gordon equation coupled to the Poisson equation for ...

Success in Salsa: Students' Evaluation of the Use of Self-Reflection When Learning to Dance [PDF]

, 2005
Achievement goal theory stipulates that achievement goals guide our beliefs and behaviour (Roberts, 2001). The two main achievement goals orientations identified in the sport and physical activity literature are task and ego orientations (Nicholls, 1984).
