As a candidate bound for the Binary Black Hole(BBH) merger events detected by LIGO/Virgo, Primordial Black Holes(PBHs)provide a useful tool to investigate the primordial curvature perturbations on small scales. Using the GWTC-1 to GWTC-3 catalogs, under the scenario that PBHs originate from large primordial curvature perturbations on small scales during infiationary epoch, we for the first time reconstruct the power spectrum of primordial curvature perturbations on small scales. It is found that the value of the amplitude of the primordial power spectrum is enhanced to O(10-2)on scales O(1) pc. This may imply the validity of PBH as a possible BBH merger candidate.

A left-sided gallbladder without a right-sided round ligament,which is called a true left-sided gallbladder,is extremely rare.A 71-year-old woman was referred to our hospital due to a gallbladder *** tomography(CT) revealed not only a gallbladder polyp but also the gallbladder located to the left of the round ligament connected to the left umbilical *** portography revealed that the main portal vein diverged into the right posterior portal vein and the common trunk of the left portal vein and right anterior portal *** cholangiography revealed that the infraportal bile duct of segment 2 joined the common bile *** cholecystectomy was performed for a gallbladder polyp,and the intraoperative finding showed that the cholecystic veins joined the round ligament.A true left-sided gallbladder is closely associated with several anomalies; therefore,surgeons encountering a true left-sided gallbladder should be aware of the potential for these anomalies.
