Colour octet extension of 2HDM [PDF]

International Journal of Modern Physics A, 2016
In this paper we consider some aspects of the Manohar–Wise extension of the SM with a colour-octet electroweak-doublet scalar applied to 2HDM. We present theoretical constraints on the parameters of this extension to both the SM and the 2HDM and discuss related phenomenology at LHC.

Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

Advanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

Machine Learning‐Driven Grayscale Digital Light Processing for Mechanically Robust 3D‐Printed Gradient Materials

Advanced Materials, EarlyView.
A machine learning‐driven grayscale digital light processing (g‐DLP) platform integrates optimization of gradient structures and photocurable resin materials with extensive tunability. The optimized gradient structure, fabricated from developed polyurethane acrylates with enhanced damping and customizable stiffness, reduces stress concentration ...

Octet lattice-based plate for elastic wave control

Scientific Reports, 2022
Motivated by the importance of lattice structures in multiple fields, we numerically investigate the propagation of flexural waves in a thin reticulated plate augmented with two classes of metastructures for wave mitigation and guiding, namely ...

Evolution of global and local deformation in additively manufactured octet truss lattice structures

Additive Manufacturing Letters, 2021
Additively manufactured lattice truss structures, often referred to as architected cellular materials, present significant advantages over conventional structures due to their unique characteristics such as high strength-to-weight ratios and surface area-

Biomechanical Performance of Additively Manufactured Bone‐Mimicking Scaffolds with Graded Architectures

Advanced Materials Technologies, EarlyView.
Nozzle temperature of 180 °C suits well for supportless PLA stochastic scaffolds. The scaffolds exhibit higher strength and stiffness under sudden impact loading. Grading type shows significant influence on scaffold properties. Radial descending type performs best in both mechanical and permeability aspects. Graded stochastic scaffolds are suitable for

The hidden charm pentaquarks are the hidden color-octet uud baryons?

Physics Letters B, 2017
The I(JP)=12(12−), 12(32−), and 12(52−) uudcc‾ pentaquarks are investigated by the quark cluster model. This model, which reproduces the mass spectra of the color-singlet S-wave q3 baryons and qq‾ mesons, also enables us to evaluate the quark interaction

Massive color-octet bosons and pairs of resonances at hadron colliders

, 2009
We analyze collider signatures of massive color-octet bosons whose couplings to quarks are suppressed. Gauge invariance forces the octets to couple at tree level only in pairs to gluons, with a strength set by the QCD gauge coupling.
