By analyzing 238 articles published between 2007 and 2023 from the Web of Science database, we identify trends, patterns, and research gaps in this rapidly evolving field. Our methodology combines performance analysis and science mapping to provide a systematic review of the way in which marketing analytics shapes market orientation strategies. The findings reveal a significant increase in research attention over the past decade but also highlight substantial gaps in general understanding of the ways in which data-driven market orientation impacts business performance. We identify key research opportunities in areas such as B2B big data analytics, innovation and internationalization through analytics, and the development of data-driven capabilities. The study makes both theoretical and practical contributions, synthesizing current knowledge and identifying future avenues of research. For practitioners, it offers insights into ways of leveraging analytical tools for enhanced market orientation, while for researchers, it maps unexplored territories in the field. In particular, the analysis emphasizes the need for a more in-depth investigation into big data analytics capabilities, customer analytics capabilities, and their strategic value in market orientation.

In this work, we propose the qubit error probability (QEP), a device specific metric that combines relaxation, dephasing, gate, and measurement contributions into a single per qubit figure of merit computable before execution. Leveraging QEP as the control variable, we revisit zero noise extrapolation (ZNE) by adding pairs of controlled native two-qubit gates on all connected qubit pairs to generate circuits with successively larger mean QEP; the zero error limit is then approximated by a linear regression of the measured observable against those values. Benchmarking on IBM Quantum Heron processors, we apply QEP guided ZNE to first order Trotterized simulations of the two dimensional transverse field Ising model, chosen as a representative interacting many body system, involving up to 68 qubits and 15 Trotter steps. In regimes where the raw circuits exhibit a finite mean QEP, the method suppresses observable errors beyond those attainable with circuit depth scaled ZNE, while requiring only three noise scaled evaluations and no additional classical post processing. These results demonstrate that QEP serves as a transparent and efficient error metric and that its integration into ZNE provides a practical route to reliability gains on current superconducting hardware, without the resource costs associated with full quantum error correction.

This work presents a 3D finite element implementation for simulating frictionless rough contacts in coated bodies, generating pseudo-elliptical contact areas. The contact is simplified to a flat deformable body with equivalent material properties against a rigid rough surface of equivalent curvatures, lowering computational cost. An efficient contact resolution algorithm that resolves overlaps and avoids artificial adhesion is introduced. Results match analytical and BEM solutions, with an order of magnitude speedup over the penalty method. Elliptical contact analysis shows that roughness asperities increase surface contact stresses and that coatings can contain high stresses inside the stronger layer.

The design of these inserts was guided by topology optimisation and refined to align with additive manufacturing principles. The feasibility of embedding 3D-printed inserts was demonstrated, yielding hybrid parts with consistent quality, accurate positioning, and a defect-free insert/moulded part interface. Mechanical testing under three-point bending revealed substantial performance gains: stiffness, strength, deflection, and energy absorption improved by factors of up to 1.5, 3.5, 1.4, and 12, respectively. A 45 % reduction in insert thickness further enhanced manufacturability and interfacial bonding, shifting the failure mode from interfacial delamination at the rib base to fibre rupture at the rib tip. Despite the reduced material volume, stiffness decreased by only ∼17 %, while strength remained stable and toughness improved significantly.
