The purpose of this study was to investigate auditory-motor learning via discrete and continuous auditory feedback using pitch and spatial lateralization. Sixteen subjects used facial surface electromyography (sEMG) to control a human-machine-interface (HMI). The output of the HMI was a lateralized harmonic tone. The fundamental frequency and lateralization (left-right ear) changed with the sum...

The Hamilton Rating Scale for Depression (HAM-D) and the Montgomery-Asberg Depression Rating Scale (MADRS), two widely used depression scales, each have unique advantages and limitations for research. The HAM-D's limited sensitivity and multidimensionality have been criticized, despite the scale's popularity. The MADRS, designed to be sensitive to treatment changes, is briefer and more uniform....

BACKGROUND Platelet-rich plasma (PRP) has been suggested as a therapeutic intervention for female androgenetic alopecia. OBJECTIVE To perform a pilot study on the effect of PRP scalp injections in women with female androgenetic alopecia. MATERIALS AND METHODS This double-blind, multicenter, placebo-controlled study compared the effect of PRP with that of saline placebo as scalp injection. T...

In the framework of rehabilitation robotics, a major role is played by the human-machine interface (HMI) used to gather the patient's intent from biological signals, and convert them into control signals for the robotic artifact. Surprisingly, decades of research have not yet declared what the optimal HMI is in this context; in particular, the traditional approach based upon surface electromyog...

BACKGROUND Activation of the WNT/β-catenin pathway has emerged as a potential therapeutic target in androgenetic alopecia (AGA). Methyl vanillate (MV) - a safe plant-derived ingredient - has been recently shown to activate the WNT/β-catenin signaling. Objectives Two distinct substudies were conducted. First, we designed a 6-month, uncontrolled, open-label clinical study to investigate whether t...

The work develops a redundant software system for subsea blowout preventers, including control logics, human-machine interface (HMI) programs, remote access and redundant databases in order to meet the high reliability requirement of subsea drilling. The Bayesian networks (BN) for control logics, HMI programs and redundant databases are built and then the whole BN are established. The quantitat...

Cognitive models allow predicting some aspects of utility and usability of human machine interfaces (HMI), and simulating the interaction with these interfaces. The action of predicting is based on a task analysis, which investigates what a user is required to do in terms of actions and cognitive processes to achieve a task. Task analysis facilitates the understanding of the system’s functional...

In offshore plant, the process control system manages process variables and interfaces with all plant utilities. It consists of workstations, controllers and various field interface devices. Plant operators deal with a large variety of process variables using the Human-Machine Interface application (HMI) in operator stations, which is a software program to interact with plant operators and to c...

Several ultrasound-based imaging modalities have been proposed for image guidance and monitoring of high-intensity focused ultrasound (HIFU) treatment. However, accurate localization and characterization of the effective region of treatment (focal spot) remain important obstacles in the clinical implementation of HIFU ablation. Harmonic motion imaging for focused ultrasound (HMIFU) is a HIFU mo...

Statement of interest Different studies show (e.g., [1]) that over 80% of today’s innovations in the automotive industry are based on car electronics and its software. These innovations can be categorized into hidden technologies (e.g., ASP, ESP), comfort functions (e.g., navigation, communication, entertainment) or driver assistance (e.g., distance checking). Especially the last two categories...
