Event-Triggered Data-Driven Robust Model Predictive Control for an Omni-Directional Mobile Manipulator

Actuators
Omni-directional mobile manipulators (OMMs) are inherently nonlinear, strongly coupled, and multiple-input multiple-output systems, posing significant challenges in developing accurate mechanistic models due to their complexity.

Testing for Genetic Interactions in Complex Disease With Distance Correlation

Biometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT Understanding epistasis (genetic interaction) may shed some light on the genomic basis of common diseases, including disorders of maximum interest due to their high socioeconomic burden, like schizophrenia. Distance correlation is an association measure that characterizes general statistical independence between random variables, not only the ...

Data-Driven Linear Representations of Forced Nonlinear MIMO Systems via Hankel Dynamic Mode Decomposition with Lifting

Mathematics
Modeling forced nonlinear multivariable dynamical systems remains challenging, particularly when first-principles models are unavailable or strong nonlinear couplings are present.

Uncovering Pathways to Occupational Health and Safety (OHS): Presenteeism and Psychosocial Safety Climate in the JD–R–OHS Model

Stress and Health, Volume 42, Issue 5, October 2026.
ABSTRACT Occupational health and safety (OHS) remains a critical concern, yet the psychosocial mechanisms linking job demands and leadership to safety behaviors and motivation remain underexplored within the Job Demands–Resources (JD‐R) framework. This three‐wave longitudinal study extended the JD‐R‐OHS model to examine Psychosocial Safety Climate (PSC)

How and when customer cyber incivility relates to employees' work and nonwork outcomes: The roles of ego depletion and social support

Applied Psychology, Volume 75, Issue 5, October 2026.
Abstract As service delivery moves further online, customer–employee exchanges are shifting from traditional face‐to‐face encounters to computer‐mediated interactions. Although research has extensively documented the adverse effects of customer incivility in face‐to‐face service settings, little is known about its online counterpart (i.e., customer ...

Direct Construction of Quantized Tensor Trains With Small Rank for Laplace‐ or Gaussian‐Transformed Analytic Functions

International Journal for Numerical Methods in Engineering, Volume 127, Issue 18, 30 September 2026.
ABSTRACT Preparing quantum states with desired amplitude distributions is a key bottleneck in the implementation of quantum linear and nonlinear dynamics solvers, including Linear Combination of Hamiltonian Simulation (LCHS) and Schrödingerization. We present a direct, closed‐form construction of Quantized Tensor Train (QTT) representations for two ...

Microwave‐Assisted Alcoholysis of Ethylene–Vinyl Acetate: Phenomenological and Thermal Evolution of EVAOH Terpolymers

Journal of Applied Polymer Science, Volume 143, Issue 36, September 20, 2026.
Microwave‐assisted alcoholysis converts EVA into EVAOH terpolymers, promoting a progressive transition from EVA‐like crystallites to VOH‐rich hydrogen‐bonded crystalline domains. Solvent‐controlled swelling influences conversion kinetics, while thermal analysis reveals a sigmoidal increase in melting temperature that a two‐population crystallization ...

A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT A stable sequential quadratic numerical optimization technique is proposed to compute critical flutter speeds without resorting to complex algebra. The solution of the traditional eigenproblem stated in the frequency domain, and whose complex conjugate eigenvalues provide insights on the stability of the dynamic aeroelastic response, is ...
