Iron pyrite (FeS(2)) is a naturally abundant and nontoxic photovoltaic material that can potentially make devices as efficient as silicon-based ones; however existing iron pyrite photovoltaic devices contain thermodynamically unstable FeS(2) film surfaces that lead to low open circuit voltages. We report the rational synthesis of phase pure, highly crystalline cubic FeS(2) nanocrystals (NCs) us...

In [14], Shelton et al. presented two Genetic and Evolutionary Methods (GEMs) that evolved feature extractors (FE) for facial recognition. One of the methods presented evolved FEs that consisted of non-uniform, overlapping “patches” that did not cover the entire image. The other was similar with the exception that it evolved FEs that consisted of patches that were of uniform size. The two GEMs,...

For over 40 years, research labs have been developing gait assist systems that use electrical stimulation of muscle to restore function to limbs paralyzed as a result of spinal cord injury. The concept of functional electrical stimulation (FES) is simple, but realization is challenging. While there are some similarities between FES-aided gait and a bipedal robot walking machine, there are also ...

BACKGROUND Functional electrical stimulation (FES) has shown benefits in patients with chronic heart failure. Therefore, it is possible that FES can benefit patients similarly after cardiac surgery. OBJECTIVE This randomized placebo-controlled trial aimed to evaluate the effects of FES on lower limb functional capacity, strength, endurance, and muscle mass after discharge from cardiac surgery...

OBJECTIVE To test if functional electrical stimulation (FES) can enhance the recovery of upper extremity function during early stroke rehabilitation. METHODS Open-label block-randomized trial, begun during inpatient rehabilitation and continued at the patients' home. Patients were assigned to either FES combined with task-specific upper extremity rehabilitation (n = 7) or a control group that...

This paper presents new approach for time series data classification using Fuzzy Expert System (FES). In the proposed study, the power disturbance signals are considered as time series data for testing the designed FES. Initially the time series data are pre-processed through the advanced signal processing tool such as S-transform and various statistical features are extracted, which are used a...

Hybrid robotic systems represent a novel research field, where functional electrical stimulation (FES) is combined with a robotic device for rehabilitation of motor impairment. Under this approach, the design of robust FES controllers still remains an open challenge. In this work, we aimed at developing a learning FES controller to assist in the performance of reaching movements in a simple hyb...

Mitochondria are the site of assembly of FeS centers of mitochondrial and cytosolic FeS proteins. Various microaerophilic or anaerobic unicellular eukaryotes lack typical mitochondria ("amitochondriate" protists). In some of these organisms, a metabolically different organelle, the hydrogenosome, is found, which is thought to derive from the same proteobacterial ancestor as mitochondria. Here, ...

Fat embolism syndrome (FES) is a life-threatening condition in which multiorgan dysfunction manifests 48-72 hours after long bone or pelvis fractures. Right ventricular (RV) failure, especially in the setting of pulmonary hypertension, is a frequent feature of FES. We report our experience treating 2 young, previously healthy trauma patients who developed severe hypoxemia in the setting of FES....

Grasping power (GP) by means of functional electrical stimulation (FES) was measured in a patient with C6 complete tetraplegia. This was compared with GP by means of the dynamic tenodesis effect, the flexor hinge splint and the GP of normal female. Palmar grasp strength by means of FES was approximately 16 % of the control group and 2.4 times greater than the flexor hinge splint. Lateral grasp ...
