Investigation of Microstructural, Mechanical, and Tribological Properties of TiC and MWCNT Reinforced Hot-Pressed Scalmalloy^® Hybrid Composites

Lubricants
In this study, hybrid composite materials were fabricated using a Scalmalloy® matrix with fixed multi-walled carbon nanotube (MWCNT, 0.8%) content and varying titanium carbide (TiC; 5%, 10%, 15%) reinforcements via the hot-pressing method.

Machine learning assisted investigation of defect influence on the mechanical properties of additively manufactured architected materials

, 2022
Additive manufacturing techniques can introduce defects that worsen the mechanical properties of 3D printed parts. Current techniques for quantifying the detrimental effects of these defects can only provide detailed analysis for a small number of ...

A power-based perspective of mechanical systems [PDF]

, 2005
This paper is concerned with the construction of a power-based modeling framework for a large class of mechanical systems. Mathematically this is formalized by proving that every standard mechanical system (with or without dissipation) can be written as ...

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Randomness in Classical Mechanics and Quantum Mechanics [PDF]

Foundations of Physics, 2010
The Copenhagen interpretation of quantum mechanics assumes the existence of the classical deterministic Newtonian world. We argue that in fact the Newton determinism in classical world does not hold and in classical mechanics there is fundamental and irreducible randomness.

First-Principles Investigation of Diverse Properties of X₂CaTa₂O₇ (X = Li, Na, K, and Rb) Ruddlesden–Popper Compounds for Photovoltaic Applications

Crystals
For the first time, we explored the optical, electronic, mechanical, and structural properties of the Ruddlesden–Popper phase family member X2CaTa2O7 (X = Li, Na, K, and Rb) by using density functional theory (DFT) with the Perdew–Burke–Ernzerhof (PBE ...

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.
