Current methods to build dynamic optical coherence tomography (OCT) volumes of the beating embryonic heart involve synchronization of 2D+time slice-sequences acquired over separate heartbeats. Temporal registration of these sequences is performed either through gating or postprocessing. While synchronization algorithms that exclusively rely on image-(More)
Capturing the dynamics of individual structures in the embryonic heart is an essential step for studying its function and development. Label-free brightfield (BF) microscopy allows for higher acquisition frame-rates than techniques requiring molecular labeling, without interfering with embryo viability or needing complex equipment. However, since different(More)
CONTEXT Spontaneous perforation of rectum is a rare event; however evisceration of the small bowel through the perforated site without predisposing factors is extremely rare, complex and worth reporting. CASE REPORT A 14 years old presented to us apparently as a case of intussception. The operative findings revealed it to be a case of spontaneous(More)
Bright-field (BF) microscopy enables imaging the beating embryonic zebrafish heart at high frame rates, thereby revealing motion of both tissues that form the heart and red blood cells (RBCs). However, single-channel BF images lack the specificity seen in multi-color fluorescence microscopy since all structures in the field of view contribute similarly to(More)
As larger ATM networks are being installed, the performance issues relating to Private Network to Network Interface(PNNI) protocol, which provides link state based dynamic routing capability in an ATM network have assumed significance. The factors influencing the selection of topology of a network, the number of nodes in the network which share topology(More)
—In index modulation schemes, information bits are conveyed through indexing of transmission entities such as antennas, subcarriers, times slots, precoders, subarrays, and radio frequency (RF) mirrors. Index modulation schemes are attractive for their advantages such as good performance, high rates, and hardware simplicity. This paper focuses on index(More)
High-speed, bright-field (BF) microscopy of the beating embryonic zebrafish heart reveals both static background structures as well as the rapid motion of cardiac tissues and red blood cells (RBCs). However, all structures contribute to BF image contrast, making labeling and subsequent analysis of these images difficult. We review our progress to separate(More)
Complete pancreatic transection following blunt abdominal trauma is not a common injury. Distal pancreatectomy with or without splenectomy is routinely performed if the transection is to the left of the superior mesenteric vessels. We performed pancreaticojejunostomy on a six-year-old female patient who presented with complete transection at the pancreatic(More)
