We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to construct rotating brane solutions which preserve exotic fractions of supersymmetry. We also investigate the superposition of rotations with intersecting branes at angles and we find new rotating intersecting branes at ang...

Ship detection with rotated bounding boxes in synthetic aperture radar (SAR) images is now a hot spot. However, there are still some obstacles, such as multi-scale ships, misalignment between anchors and features, the opposite requirements for spatial sensitivity of regression tasks classification tasks. In order to solve these problems, we propose balanced feature-aligned network (RBFA-Net) wh...

The effect of Lewis acid on the structure and H2 productivity of a diiron dithiolate complex was investigated by using density functional theory (DFT) calculations. When a model molecule of [(CH3SH)(CO)2Fe(p)(mu-SCH2NHCH2S)Fe(d)(CO)3] was geometrically optimized, two isomers were found: one is the unrotated structure (1) with no ligand between two Fe atoms and the other is the rotated structure...

Multiple Input Multiple Output (MIMO) has become one of the most exciting field in modern engineering.It has become one of the key technologies for wideband wireless communication systems.It is mainly used to increase capacity and data rate of any wireless systems.In this paper,we exploit the space and time diversity to decode the quasi and rotated quasi space time block codes (QOSTBC) based on...

This paper explains a calculational design technique for ne-grained parallel programs by means of an example. The example deals with the recognition of K-rotation invariant (or K-rotated) segments which is a generalisation of the well-known square recognition problem. Two parallel programs are derived. The rst one determines for each segment of N successive inputs whether it is K-rotated, the l...

This paper investigates how to improve the worst case runtime of INSERTION SORT while keeping it in-place, incremental and adaptive. To sort an array of n elements with w bits for each element, classic INSERTION SORT runs in O(n) operations with wn bits space. GAPPED INSERTION SORT has a runtime of O(n lg n) with a high probability of only using (1+ )wn bits space. This paper shows that ROTATED...

Hebrew-speaking students performed lexical decisions on Hebrew letter strings that appeared at different orientations. Response times evidenced a strong interaction between string length and orientation. At angular deviations of less than 60 degrees from the upright, neither orientation nor string length had any effect, suggesting that words were directly, and probably holistically, recognized....

Much recent interest surrounds listeners' abilities to adapt to various transformations that distort speech. An extreme example is spectral rotation, in which the spectrum of low-pass filtered speech is inverted around a center frequency (2 kHz here). Spectral shape and its dynamics are completely altered, rendering speech virtually unintelligible initially. However, intonation, rhythm, and con...

In this paper we introduce rotated constellations of signals in multi-carrier code-division multiple-access (MC CDMA). The performance of this new system is obtained and compared to that of conventional MC-CDMA system. Numerical results consider a typical indoor environment.
