Rotating cells have been reported in past. Rotation of cells and cell clusters has been associated with migration and development. This observation reports for the first time a rotating cluster of cells isolated from the hippocampi of neonatal mouse pups. The speed of rotation in these clusters is immensely high. Further analysis of such rotating neurons can shed valuable clues on the origin of...

Considerable research effort has been devoted to predicting the secondary structure of proteins from their amino acid sequences. Despite the plethora of prediction techniques, present methods typically have 76% approximate level of accuracy on an average. Thus, there is a considerable room for improvement. We present here a novel automated approach for the secondary structure prediction based o...

Symmetries of multi-anyon wavefunctions are analysed with the help of a second quantized formulation. Analogues of Slater determinants are constructed. It is shown that the Pauli principle is not enforced. e-mail address [email protected]

The investigation of the possibility of a trineutron CSn) bound state has received considerable attention. The experimental evidence of the bound state of 3n with the binding energy of 1 MeV was once reported by Ajdacic et al. 1> and Kim et al.;> while all other numerous measurements could not find the evidence of the bound state.') In calculations of the bound state of 3n there exist contradic...

Skenario interaksi manusia-robot adalah sangat rumit dan memerlukan definisi yang tepat dari variabel lingkungan untuk pengujian yang ketat aspek-aspek berbeda perilaku robot. Kondisi lingkungan mempengaruhi perilaku manusia dan robot, sehingga manusia dan robot merespon berbeda pada kondisi akustik atau pencahayaan berbeda. Pada penelitian ini dilakukan eksperimen berulang-ulang dengan manusia...

Pattern discovery in unaligned DNA sequences is a fundamental problem in computational biology with important applications in finding regulatory signals. Current approaches to pattern discovery focus on monad patterns that correspond to relatively short contiguous strings. However, many of the actual regulatory signals are composite patterns that are groups of monad patterns that occur near eac...

These are the lecture notes from Professor Andrew Strominger’s Physics 211r: Black Holes from A to Z course given in Spring 2015, at Harvard University. It is the first half of a survey of black holes focusing on the deep puzzles they present concerning the relations between general relativity, quantum mechanics and thermodynamics. Topics include: causal structure, event horizons, Penrose diagr...
