Rising on columns of fire, rockets launched to the moon – and I who'd wished to work with astronauts, am assigned instead to weigh SAC bomber crew immersed in water – measure " lean body mass, " wondered what difference a paunch on a pilot would make sitting in a B52. Silent— eyes hidden behind red goggles, they swaggered in their muscled nakedness into my lab. Dark-adapted to their cockpits, r...

OBJECTIVE To reveal the structural characteristics of the sinoatrial node (SAN) and the distribution of hyperpolarization-activated cyclic nucleotide-gated cation channels (HCN) in the SAN in the mouse. METHODS The structure of the SAN and the distribution of HCN channels in the SAN in the mouse were studied by histology and immunolabelling of ANP, Cx43 and HCN channels. RESULTS The mouse S...

Surface electrode recordings cannot delineate the activation within the human or canine sinoatrial node (SAN) because they are intramural structures. Thus, the site of origin of excitation and conduction pathway(s) within the SAN of these mammals remains unknown. Canine right atrial preparations (n=7) were optically mapped. The SAN 3D structure and protein expression were mapped using immunohis...

San Francisco Crime Classification is an online competition administered by Kaggle Inc. The competition aims at predicting the future crimes based on a given set of geographical and time-based features. In this paper, I achieved a an accuracy that ranks at top %18, as of May 19th, 2016. I will explore the data, and explain in details the tools I used to achieve that result.
