We surveyed 1.75 square degrees of sky near Neptune to an R-band 50% detection efficiency of 25.8 mags (corresponding to radii of about 17 km for an assumed albedo of 0.04). We discovered one new outer satellite, Psamathe (S/2003 N1), about 20 km in radius and having a distant retrograde orbit and moderate eccentricity. Until 2003 Neptune was only known to have two satellites which exhibited or...

Let $D$ be a finite simple digraph with vertex set $V(D)$ and arcset $A(D)$. A twin signed total Roman dominating function (TSTRDF) on thedigraph $D$ is a function $f:V(D)rightarrow{-1,1,2}$ satisfyingthe conditions that (i) $sum_{xin N^-(v)}f(x)ge 1$ and$sum_{xin N^+(v)}f(x)ge 1$ for each $vin V(D)$, where $N^-(v)$(resp. $N^+(v)$) consists of all in-neighbors (resp.out-neighbors) of $v$, and (...

INTRODUCTION Twin-to-twin transfusion syndrome (TTTS) is the most common serious complication of monochorionic (MC) twin pregnancies, with perinatal mortality rates of up to 90% if untreated. This study aimed to review the perinatal and perioperative outcomes of MC twin pregnancies treated for TTTS by fetoscopic laser photocoagulation (FLP) since its introduction at KK Women's and Children's Ho...

The US Global Positioning System (GPS) and the USSR (and later Russian) system Glonass have existed for decades. Europe is developing Galileo and China launched Beidou which was the first Regional Navigation Satellite System (RNSS) and then announced Compass, a Global Navigation Satellite System (GNSS). Japan is planning its own regional augmentation to GPS and Galileo known as the Quasi-Zenith...

Background: Prediction of adverse perinatal and postnatal outcomes could be possible by using ultrasound Doppler evaluation, however there are some controversies regarding this issue in the literature. The goal of present study was to evaluate predictive value of Doppler indices in single and twin pregnancies during second trimester. Materials and Methods: This prospective study was conducted i...
