Energy–momentum tensor in the microscopic plasma model
, 1976 An energy–momentum tensor for the microscopic plasma model is constructed from the action integral by allowing for dynamics of special relativity. The energy density is then identified with the 44-component of the energy–momentum tensor.

Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Brane stability under $$f(Q,{\mathcal {T}})$$ f ( Q , T ) gravity
European Physical Journal C: Particles and FieldsThe focus of this paper is to investigate the behavior of a codimension-one thick brane in the modified symmetric teleparallel gravity structure $$f(Q, {\mathcal {T}})$$ f ( Q , T ) , where Q is the nonmetricity scalar and $${\mathcal {T}}$$ T is the ...

On functional representations of the conformal algebra
European Physical Journal C: Particles and Fields, 2017 Starting with conformally covariant correlation functions, a sequence of functional representations of the conformal algebra is constructed. A key step is the introduction of representations which involve an auxiliary functional.

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades
Advanced Science, EarlyView.Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Nuclear Physics BTo fully clarify the invariance of the classical Liouville field theory under the Virasoro algebra, we first elucidate in detail the concept of classical anomaly, discuss the occurrence of two symmetry algebras associated to this theory, and provide some

Initial correlations of the Glasma energy-momentum tensor
Journal of High Energy Physics, 2019 We present an analytical calculation of the covariance of the energy-momentum tensor associated to the gluon field produced in ultra-relativistic heavy ion collisions at early times, the Glasma.

Advanced Science, EarlyView.A metasurface‐enabled helical wavefront fingerprint (MHWF) paradigm is proposed for quantitative and specific retrieval of a liquid medium's refractive index and extinction coefficient. The liquid's complex dielectric response governs the wavefront evolution of the metasurface‐generated focused vortex beam, forming a distinctive three‐dimensional ...

Proposal for the proper gravitational energy–momentum tensor [PDF]
Modern Physics Letters A, 2016 We propose a gravitational energy–momentum (GEMT) tensor of the general relativity obtained using Noether’s theorem. It transforms as a tensor under general coordinate transformations. One of the two indices of the GEMT labels a local Lorentz frame that satisfies the energy–momentum conservation law.

Advanced Science, EarlyView.Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...
