Optimal periodic output feedback control: a continuous-time approach [PDF]

open access: yes, 2007
: This paper addresses the problem of optimal static output feedback control of linear periodic systems. The proposed approach, which allows to deal with both stable and unstable open loop systems, relies on a continuous-time formulation of the control ...

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

open access: yesInternational Journal of Climatology, EarlyView.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...

Spatio‐Temporal Analysis of Human Thermal Comfort and Relationships With Large‐Scale Climate Indices Along Ghana's Coastal‐Urban Corridor From 1980 to 2020

open access: yesInternational Journal of Climatology, EarlyView.
Four decades of UTCI data show increasing thermal stress along Ghana's coastal‐urban corridor, with very strong heat‐stress days rising by about 1.4 days/year. Random Forest–SHAP analysis with temporal validation identified AOD as the strongest model‐based predictor of monthly UTCI variability, followed by TSA, WHWP, and AMO.

Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

open access: yesThe Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Vocal Outcomes After Cell‐Based Outer Vocal Fold Implant in Porcine Bilateral Vocal Fold Resection

open access: yesThe Laryngoscope, EarlyView.
Cell‐based outer vocal fold replacement (COVR) was evaluated in a porcine model of bilateral vocal fold injury using longitudinal acoustic analysis and histologic assessment. COVR implantation resulted in recovery of the nonperiodic acoustic parameter Q50 to preoperative levels by 6 months, with implanted human adipose‐derived stem cells detected in 7 ...

Assembling Engagement With Autonomy and Language ‐ A Neuroscientific Case Study With Digital Companions

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT This study addresses the need to understand human engagement with empathic Generative Artificial Intelligence (GenAI) digital companions (DC), as these systems increasingly fulfil social and emotional roles in daily life. Motivated by the rapid adoption of DC technologies and their potential to reshape human–AI relationships, the study applies

Acute and Chronic Local Field Potential Recordings in Dystonia—A Systematic Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Dystonia is a hyperkinetic movement disorder increasingly conceptualized as a disorder of distributed network dysfunction involving the basal ganglia, cortex and cerebellum. Local field potentials (LFPs) recorded from deep brain stimulation (DBS) electrodes provide a unique opportunity to characterize the electrophysiological signatures ...

Lower Urinary Tract Symptoms as Diagnostic Clues in Parkinsonism: A Practical Framework for Neurologists

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Lower urinary tract symptoms (LUTS) are among the most prevalent nonmotor complaints across the parkinsonian spectrum, yet they remain underutilized as diagnostic and management signals in neurology practice. Although prior reviews have characterized disease‐specific patterns of urinary dysfunction, and recent guidelines address ...

Driving Cerebellar Theta Oscillations Interferes With Voluntary Neck Movements in Cervical Dystonia

open access: yesMovement Disorders, EarlyView.
Abstract Background Cervical dystonia (CD) is a movement disorder with a complex pathophysiology, including cerebellar abnormalities. Transcranial alternating current stimulation (tACS), a noninvasive neuromodulation technique capable of entraining brain oscillations, can transiently modulate neuronal activity and enhance resonant rhythms.
