Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se2 Solar Cells for Tandem Applications

Small, Volume 22, Issue 52, 16 September 2026.
A complete loss analysis has been carried out on the state‐of‐the‐art 1.0 eV bandgap (Ag,Cu)(In,Ga)Se2 solar cells, which are of interest for tandem devices. The most significant loss mechanisms are found in the open‐circuit voltage, due to non‐radiative losses in the chalcopyrite absorber, and in the fill factor, caused by space‐charge region ...

Towards predictive maintenance of lithography systems: Robust fault diagnosis via LPV-to-LTI reformulation

Results in Engineering
Fault diagnosis plays a critical role in predictive maintenance of high-precision mechatronic systems, such as lithography machines, where unplanned downtime can cause substantial economic losses.

Flight evaluation of simultaneous actuator/sensor fault reconstruction on a quadrotor minidrone

IET Control Theory & Applications, 2021
In view of the increase in the number of Unmanned Aerial Vehicles (UAVs) in the commercial and private sectors, it is imperative to make sure that such systems are safe, and thus resilient to faults and failures. This paper considers the numerical design

Average Dwell Time Based Smooth Switching Linear Parameter-Varying Proportional-Integral-Derivative Control for an F-16 Aircraft

IEEE Access, 2021
Switching control methods have great potential applications in flight control system design. However, nonsmooth control commands at switching instants could lead to performance degradations or bring in safety risks. This paper presents a smooth switching

Impact of Carina Width on Re‐Ablation Rate of Atrial Fibrillation After Primary Cryoballoon‐Ablation

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 9, Page 1947-1955, September 2026.
Right side carina width is associated with the incidence of reconnection of RPVs and re‐ablation. Increased left side carina width was associated with re‐ablation rate, but there was no association with reconnection of the LPVs. ABSTRACT Background Reconnection of the pulmonary veins (PVs) is the primary cause of atrial fibrillation (AF) episodes after

Performance Optimization with LPV Synthesis for Disturbance Attenuation in Planar Motors

Mathematics
Optimizing the performance of motion control systems with variations in nonlinear parameters is not an easy task. To accomplish this task, it is important to design the controller using the linear system approach.

Revisiting Variable Stars Toward the Globular Cluster NGC 6496 With ATLAS and Gaia Photometry

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We revisit 13 variable stars in the field of the metal‐rich globular cluster NGC 6496, discovered by Abbas et al. (2015; Astronomical Journal 149:40) (hereafter referred to as “MA15”) via time‐series data, spanning 2 years. We improve upon the MA15 characterization of the variables using ATLAS time‐series photometry data, spanning 8 years, in ...

Analysis and Controller Design for Parameter Varying T-S Fuzzy Systems with Markov Jump

Mathematics
In this paper, we investigate a novel T-S fuzzy parameter varying system with Markov jump, in which parameters depend not only on a Markov chain but also on linear parameter varying elements that take values in convex polytopic sets.

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, Volume 13, Issue 8, Page 1848-1860, August 2026.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

LPV control of a gyroscope with inverted pendulum attachment

, 2018
\u3cp\u3eA linear parameter varying (LPV) optimal L\u3csub\u3e2\u3c/sub\u3e gain controller is designed with mixed-sensitivity shaping to stabilize an inverted pendulum attached to a control moment gyroscope (CMG). Swing-up of the pendulum is achieved by
