Journal of the American College of Cardiology, 2006 We sought to characterize the clinical nature of atrial flutter (AFL) in a large cohort of infants.There are no large studies describing the natural history of AFL in infants. Previous studies vary in the therapy used and expected prognosis.We reviewed the records of all children younger than 1 year of age who were diagnosed with AFL at our hospital ...

Advanced Photonics Research, EarlyView.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Journal of Family Medicine and Primary Care, 2018 Acute coronary syndrome (ACS) is a term used to describe a spectrum of diseases associated with sudden reduced blood flow to the heart. Coronary artery thromboembolism is recognized as an important nonatherosclerotic cause of acute myocardial infarctions in 2.9% of ACS cases, with a long-term outcome indicating that coronary embolism patients represent

High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization
Advanced Photonics Research, EarlyView.A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...

Advanced Sensor Research, EarlyView.Liquid–solid interface processes are investigated using liquid gate‐all‐around Si nanowire (NW) FET biosensors. Charge inversion effect in single‐valent ionic solutions is revealed. Behavior of input‐referred noise, SU, in NW FETs operated in physiological solutions with different pH indicates that the origin of noise is determined by ions. The results

Medical Materials and Device Innovation: Choosing the Right and Relevant Biological Models
Advanced Therapeutics, EarlyView.Choosing the right disease model is key to safe, effective medical innovation. When models reflect human biology and clinical needs, they improve translation, reduce risk, and accelerate progress. Advances in 3D tissues, organ‐on‐chip, and humanized systems offer exciting opportunities. With thoughtful selection and clinician input, biomedical research

Flutter Speed Limits of Cantilever Rectangular and Tapered Plates
Al-Khawarizmi Engineering Journal, 2007 The aerodynamic and elastic forces may cause an oscillation of the structure such as the high frequency of the airfoil surfaces and the dynamic instability occurring in an aircraft in flight and failure may occur at a speed called flutter speed.
