A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key

Dynamic Facial Expression Recognition of Learners via Adaptive Global Attention and Differential Temporal Transformer

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Analysing learners' facial expressions during learning and exploring their learning processes and emotional changes are of great significance for assisting teachers' teaching and promoting smart education. In complex learning environments, static facial expression recognition fails to capture the dynamic changes of learners' expressions losing

An iterated greedy‐based metaheuristic with local search for the rank pricing problem

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The rank pricing problem involves determining optimal prices for a set of products while accounting for customers' budgets and preferences. This study develops an iterated greedy‐based metaheuristic to efficiently solve this problem. The core idea is to generate a sequence of solutions by iteratively applying destruction and reconstruction ...

Do Fair Value Adjustments Excluded From Net Income Convey New Information That Is Complementary to GAAP Earnings?

open access: yesJournal of Business Finance &Accounting, EarlyView.
ABSTRACT We use banks’ quarterly fair value disclosures to perform the first short‐window event study of fair value adjustments excluded from net income and offer three main results. First, we find that fair value adjustments for banks’ loan portfolios are positively associated with short‐window stock returns and that they impact investors’ response to

Testing for Unspecified Periodicities in Binary Time Series

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Given random variables Y1,…,Yn$$ {Y}_1,\dots, {Y}_n $$ with Yi∈{0,1}$$ {Y}_i\in \left\{0,1\right\} $$ we test the hypothesis whether the underlying success probabilities pi$$ {p}_i $$ are constant or whether they are periodic with an unspecified period length of r≥2$$ r\ge 2 $$.

A Note on Local Polynomial Regression for Time Series in Banach Spaces

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This work extends local polynomial regression to Banach space‐valued time series for estimating smoothly varying means and their derivatives in non‐stationary data. The asymptotic properties of both the standard and bias‐reduced Jackknife estimators are analyzed under mild moment conditions, establishing their convergence rates.

Elucidating the cellular determinants of the end‐systolic pressure‐volume relationship of the heart via computational modelling

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

On curvature and the bilinear multiplier problem

open access: yesRevista Matemática Iberoamericana, 2012
We provide sufficient normal curvature conditions on the boundary of a domain D \subset \mathbb{R}^4 to guarantee unboundedness of the bilinear Fourier multiplier operator \mathrm{T}_D

Output Feedback Design for Parameter Varying Systems Subject to Persistent Disturbances and Control Rate Constraints

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 7, Page 4219-4233, 10 May 2026.
ABSTRACT This paper develops a framework for designing output feedback controllers for constrained linear parameter‐varying systems that experience persistent disturbances. We specifically propose an incremental parameter‐varying output feedback control law to address control rate constraints, as well as state and control amplitude constraints.

Analytical Floor Response Spectra for Performance‐Based Seismic Design of Non‐structural Elements in Reinforced Concrete Frame Buildings

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1292-1312, May 2026.
ABSTRACT Damage to non‐structural elements significantly impacts the seismic performance of buildings in terms of economic and functionality losses. Consequently, performance‐based seismic design of non‐structural elements has become a key pillar of a comprehensive building‐seismic resilience strategy, for instance, through loss‐targeted earthquake ...
