OBJECTIVE To investigate the surgical outcomes of hybrid total arch repair without deep hypothermic circulatory arrest for patients with acute Stanford type A aortic dissection. METHODS Retrospective review of clinical data of patients with acute Stanford type A aortic dissection who underwent surgical repair at our institution between November 2009 and… (More)
In this work, we present a new structure to realize optical logic operation in a Sagnac interferometer with electro-optical modulation. In the scheme, we divide two counterpropagation signals in a Sagnac loop to two different arms with the electro-optical crystal by using two circulators. Lithium niobate materials whose electro-optical coefficient can be as… (More)
A CW dual-frequency master oscillator power amplifier (MOPA) laser system with dozens of gigahertz (GHz) frequency separation is presented. The MOPA system consists of a monolithic microchip seed laser and a double-end pumped traveling wave power amplifier. The short length of seed laser cavity guarantees the seed signal with a large frequency separation… (More)
We demonstrate high-energy soliton pulse generation from a large mode area fiber, tunable from 1560 nm up to 1700 nm, pumped with a 10 MHz, 1.5-ps time lens source at 1544 nm.
We demonstrate a novel (to our knowledge) method for high sensitivity measurement of pulsed light at the telecommunication wavelength of 1558 nm using a GaAsP photomultiplier tube. By modulating the input power and analyzing the harmonic components, high sensitivity third-order autocorrelation is obtained in the wavelength and power regimes where a mixture… (More)
A continuous-wave microchip dual-frequency laser (DFL) with well balanced intensity was presented. In order to obtain such a balanced intensity distribution of the two frequency components, the DFL wavelengths were precisely tuned and spectrally matched with the emission cross section (ECS) spectrum of the gain medium by employing a temperature controller.… (More)
We propose a double-pumped ring cavity multiwavelength fiber optical parametric oscillator (MW-FOPO) using a highly nonlinear dispersion-shifted fiber (HNL-DSF) as the gain medium and a polarization maintained fiber based Sagnac loop filter as the comblike filter. 22-wavelength lasing of the double-pumped MW-FOPO with a ripple less than ±2.5 dB and a… (More)
OBJECTIVE To explore the efficacy and safety of recombinant human brain natriuretic peptide (rhBNP) in the patients with severe heart failure (HF). METHODS A prospective multicenter study was conducted. Patients whose age > 18 years old, and with the New York Heart Association (NYHA) cardiac function grade over III-IV, acute cardiac insufficiency and the… (More)
We demonstrate a novel method for high sensitivity measurement of pulsed light using a GaAsP photomultiplier tube. 2nd- and 3rd-order autocorrelations are obtained simultaneously by modulating the input power and analyzing the RF harmonic components.
OBJECTIVE To determine the safety and effectiveness of autotransfusion of shed mediastinal blood after open heart surgery. METHODS Sixty patients undergoing coronary artery bypass grafting (CABG) were selected randomly to receive either nonwashed shed mediastinal blood (Group 1, n = 30) or banked blood (Group 2, n = 30). Drainage and transfusion volume… (More)
