Laser powder bed fusion of planar bi-metallic thermally auxetic lattice structures
(2024)CIRP AnnalsThis study addresses challenges in design and fabrication of thermally auxetic structures with zero thermal expansion (ZTE) using multi-material laser powder bed fusion. Planar 316L-CuCr1Zr lattices with re-entrant and triangular unit cells were designed, manufactured and tested. Introducing beam curvature as a new design parameter effectively reduces the coefficient of thermal expansion (CTE) compared to standard designs with straight ...Journal Article -
Anisotropic Functionally Graded Nano-Beam Models and Closed-Form Solutions in Plane Gradient Elasticity
(2024)Applied Mathematical ModellingThis study delves into the investigation of exact analytical solutions for the plane stress and displacement fields within linear homogeneous anisotropic nano-beam models of gradient elasticity. It focuses on solving the Helmholtz equation, which encompasses a second-order non-homogeneous linear partial differential equation in plane gradient elasticity theory, utilizing polynomial series-type solutions. The analysis centers on the ...Journal Article -
Nucleobase adducts bind MR1 and stimulate MR1-restricted T cells
(2024)Science ImmunologyMR1T cells are a recently found class of T cells that recognize antigens presented by the major histocompatibility complex-I-related molecule MR1 in the absence of microbial infection. The nature of the self-antigens that stimulate MR1T cells remains unclear, hampering our understanding of their physiological role and therapeutic potential. By combining genetic, pharmacological, and biochemical approaches, we found that carbonyl stress ...Journal Article -

Phonon-limited transport in two-dimensional materials: A unified approach for ab initio mobility and current calculations
(2024)Physical Review AppliedIn this paper, we present an ab initio methodology to account for electron-phonon interactions in two-dimensional (2D) materials, focusing on transition-metal dichalcogenides (TMDCs). It combines density functional theory and maximally localized Wannier functions to acquire material data and relies on the linearized Boltzmann transport equation (LBTE) and the nonequilibrium Green's functions (NEGF) method to determine the transport ...Journal Article -
Wheat height and phenology retrieval using GPS/BDS interferometric reflectometry technology
(2024)MeasurementMonitoring vegetation growth utilizing the Global Navigation Satellite System-interferometric reflectometry (GNSS-IR) technology has obtained widespread attention in recent years. GNSS-IR based approaches demonstrate the advantageous characteristics of high temporal resolution while maintaining cost-effectiveness. Most existing studies generally utilize reflected signals to retrieve the plant height and vegetation water content, while few ...Journal Article -
Third-party countries in cyber conflict: Public opinion and conflict spillover in cyberspace
(2024)Journal of Peace ResearchThe transnational nature of cyberspace alters the role of third-party countries (TPCs) in international conflict. In the conventional environment, military operations are primarily confined to the boundaries of the combatants or a designated war zone. However, during cyber conflicts, operations may occur on the digital infrastructure of states not otherwise involved in the dispute. Nevertheless, within the cyber conflict literature, little ...Journal Article -

Does subjective wellbeing modify travel behaviour changes among older people in response to a new metro line?
(2024)Journal of Transport GeographyThis research aims to estimate how subjective wellbeing at baseline would affect the changes in travel behaviour among older people due to a new public transport infrastructure. Cross-sectional studies have begun to establish the connection between subjective wellbeing and travel behaviour, indicating that a high level of wellbeing can lead to beneficial outcomes such as active mode choice, frequent transport use, and social engagement. ...Journal Article
