Sub‐Micrometer‐Precision Path Following of Piezo‐Actuated Mobile Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This article reports on the Holonomic‐Beetle (HB), a palm‐sized robot that achieves sub‐micrometer (sub‐µm) precision path tracking across spatial ranges from 100 µm to 10 mm. Using proportional‐integral‐derivative (PID) control, the HB accurately tracks both complex and straight paths with sub‐µm path errors, surpassing existing robots.

A Neural Network‐Based Self‐Sensing Embedded Position Control System for Shape Memory Alloy Wire Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape memory alloy wires exhibit thermally induced phase changes that generate actuation strain and resistance variations enabling self‐sensing. However, hysteretic electromechanical behavior complicates accurate state estimation. This paper presents an artificial in‐based self‐sensing method to reconstruct SMA actuator position in real time, achieving

Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes

open access: yesAdvanced Intelligent Systems, EarlyView.
Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones. This work

Infertility Risk and Employment History Among US Women: Findings From National Health and Nutrition Examination Survey 2013–2014

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction It is well established that exposure to chemical, radiological, and biological hazards in the workplace are infertility risk factors. Although workplace‐specific infertility risks have been documented, the associations between employment history and infertility risk remain largely unexplored.

Acoustofluidic Patterning for Improved Microtissue Histology

open access: yesAdvanced NanoBiomed Research, EarlyView.
Microtissue histology is widely used to characterize microtissue phenotype and morphology. However, conventional microtissue histology workflows are inefficient and time‐consuming. This work introduces a novel embedding technique that uses acoustofluidics to improve the efficiency of microtissue histology and reduce the time required for data analysis.

Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

open access: yesThe Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

Design of discrete PI‐PR2 controllers for time‐delayed systems using dominant pole placement method

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a new controller structure known as the proportional‐integral proportional‐double‐retarded (PI‐PR2) designed for discrete‐time systems with time delay. The dominant pole placement technique, which is frequently encountered in control systems, is used as the primary design method. The design method starts that dominant poles

Integrating Dimensional Personality and Autistic Traits to Predict Suicidal Ideation, Suicide Attempts, and Nonsuicidal Self‐Injury in Autistic Adults

open access: yesAutism Research, EarlyView.
ABSTRACT Given the elevated rates of suicidal ideation, suicide attempts, and nonsuicidal self‐injury (NSSI) in autistic adults, we examined whether autism‐informed traits and transdiagnostic personality tendencies jointly relate to these outcomes.
