The present study aimed to investigate changes in structural gray matter (GM) volume and functional amplitude of spontaneous low-frequency oscillations (LFO) and functional connectivity density in patients with subcortical vascular mild cognitive impairment (svMCI). Structural MRI and resting-sate functional MRI data were collected from 26 svMCI patients and 28 age- and gender-matched healthy c...

Low Frequency Oscillations (LFO) occur in power systems because of lack of the damping torque in order to dominance to power system disturbances as an example of change in mechanical input power. In the recent past Power System Stabilizer (PSS) was used to damp LFO. FACTs devices, such as Unified Power Flow Controller (UPFC), can control power flow, reduce sub-synchronous resonance and increase...

At interfaces between complex oxides, electronic, orbital and magnetic reconstructions may produce states of matter absent from the materials involved, offering novel possibilities for electronic and spintronic devices. Here we show that magnetic reconstruction has a strong influence on the interfacial spin selectivity, a key parameter controlling spin transport in magnetic tunnel junctions. In...

This paper discusses the recent trends in machine learning towards learning from observation (LfO). These reflect a growing interest in having computers learn as humans do — by observing and thereafter imitating the performance of a task or an action. We discuss the basic foundation of this field and the early research in this area. We then proceed to characterize the types of tasks that can be...

Atmospheric and oceanic variability in the Arctic shows the existence of several oscillatory modes. The decadal-scale mode associated with the Arctic Oscillation (AO) and a low-frequency oscillation (LFO) with an approximate time scale of 60-80 years, dominate. Both modes were positive in the 1990s, signifying a prolonged phase of anomalously low atmospheric sea level pressure and above normal ...

OBJECT The authors conducted a cadaveric anatomical study to quantify and compare the area of surgical exposure and the freedom available for instrument manipulation provided by the following four surgical approaches to the extracranial periclival region: simple transoral (STO), transoral with a palate split (TOPS), Le Fort I osteotomy (LFO), and median labioglossomandibulotomy (MLM). METHODS...

PURPOSE Schizophrenia is a mental illness with cognitive impairments, which could be due to the abnormal neural oscillations in the brain[1]. It is believed that the neural oscillations reflect multiple physiological mechanisms in the brain networks, especially prominent in the low-frequency oscillations (LFO) [2]. Therefore, the abnormal LFO distributions may reflect the impaired cognitive fun...

STUDY OBJECTIVES Current options to enhance exercise performance in patients with COPD are limited. This study compared the effects of high flows of humidified oxygen to conventional low-flow oxygen (LFO) delivery at rest and during exercise in patients with COPD. DESIGN Prospective, nonrandomized, nonblinded study. SETTING Outpatient exercise laboratory. PATIENTS Ten patients with COPD, ...

In this study, the performance of supplementary stabilizer for static synchronous compensator (STATCOM) tuned based on particle swarm optimization method in order to improvement of dynamic stability is studied. Since STATCOM is usually used for damping Low Frequency Oscillations (LFO), a supplementary stabilizer is incorporated with STATCOM to reach the mentioned purpose. As a heuristic optimiz...
