Multiple factors determine the susceptibility to intrauterine hepatitis B virus (HBV) infection. These factors include the HBV structure, HBV mutation, HBV DNA level, placental barrier, the immune status of the mother, and the genetic make-ups of the

For generating short flat-top optical pulses, traditional methods are either bandwidth limited or have low controllability (in pulse width and shape). We propose a fiber-loop based time-lens system to realize ps-level flat-top pulses, and theoretical

The shock ignition scheme has the advantages of low ignition energy threshold, high gain, and good hydrodynamic stability, which has become one of the key schemes for the potentially successful ignition of inertial confinement fusion. The crucial ele

Hepatitis B virus (HBV) intrauterine infection remains to be an important cause for a large number of persistent hepatitis B surface antigen (HBsAg) positive carriers in areas with a high HBV prevalence, particularly in China and Southeast Asia. In t

Intrauterine hepatitis B virus (HBV) infection has been suggested to be caused by transplacental transmission that cannot be blocked by hepatitis B vaccine. This would decrease the effectiveness of hepatitis B vaccine. This study examined the risk fa

A new scheme of backward Raman scattering, in which coupling between the forward and backward Stokes processes is caused by injecting an additional backward pump field, is demonstrated both experimentally and theoretically. Four wave mixing among the

In order to solve the inverse identification problem of material dynamic constitutive parameters while cutting the thread, and obtain the parameters which can describe the material dynamic mechanical properties correctly. The MSARS algorithm was adop

Over 90% of infants infected with hepatitis B virus (HBV) caused by mother-to-infant transmission will evolve to carrier status, and this cannot be prevented until widespread administration of the HB vaccine and hepatitis B immune globulin (HBIG) is

Competition of stimulated Raman scattering was observed in hydrogen-methane mixed gases pumped by a KrF laser. The Stokes pulse of methane gas oscillated, shortened and was destroyed with the addition of various ratios of hydrogen gas. A model includ
