Toward a modular, bidirectional synthesis of (−)-mucocin

September 2011 · Tetrahedron

A convergent stereoselective synthesis of the C13–C34 fragment of (−)-mucocin is described. The salient features include (a) the bidirectional synthesis of the C-2 symmetric C13–C21 subunit, (b) regio- and stereoselective preparation of a 1,3-diol derivative from a diene activated by NBS via intramolecular nucleophilic sulfinyl group participation, (c) utilizing the self-metathesis reaction to ... [Show full abstract] prepare a functionalized C10 alkene, and (d) regio- and stereoselective intermolecular epoxide opening to construct the ether bond between C20 and C24. An organocatalytic α-hydoxylation has been employed to create the C4 stereogenic center of C1–C12 subunit. Attempted union of the two subunits utilizing the B-alkyl Suzuki coupling did not succeed.

Spinodal instabilities in expanding Fermi liquids

June 1995 · Physical Review C

In this article we investigate the influence of the expansion on the properties and the dynamical evolution of a piece of unstable nuclear matter. We discuss how the expansion modifies the spinodal decomposition of the system by deriving analytical results, which are confirmed and illustrated by numerical simulations in two dimensions. Moreover, the expansion is introducing a short freeze-out ... [Show full abstract] time which allows to unambiguously define the formed fragments. An important result of this study is that for a wide range of expansion velocities the fragmentation is dominated by the same unstable wave lengths, which happen to be weakly dependent on density and temperature provided that the system is lying well inside the spinodal instability region.

Wytrzymałość połączeń nitowanych bezotworowo-wybrane aspekty

Robert Cacko

Nitowanie jest jedną z najstarszych technik łączenia znanych człowiekowi. Źródła historyczne potwierdzają, że już w początkach Epoki Bronzu do nitowania metali używano pełnych nitów. Natomiast na przestrzeni lat, ze względu na rosnącą wiedzę w zakresie technik spawalniczych i dostępności stali spawalnych, jak i innych metali do konstrukcji, nitowanie było coraz bardziej wypierane przez tańsze ... [Show full abstract] techniki spawania. Ze względu na szereg cech, stały się one głównymi technikami łączenie w przemyśle, zwłaszcza w przypadku produkcji seryjnej i masowej. Przemysł samochodowy stanowi jedną z tych branż, w której techniki łączenia stanowią bardzo istotny fragment procesu produkcyjnego w skali masowej.

Many-Particle Quantum Dynamics in Atomic and Molecular Fragmentation

January 2003

This is the first comprehensive treatment of the interactions of atoms and molecules with charged particles, photons and laser fields. Addressing the subject from a unified viewpoint, the volume reflects our present understanding of many-particle dynamics in rearrangement and fragmentation reactions such as electron capture, target and projectile ionisation, photoabsorption and Compton ... [Show full abstract] scattering, collisional breakup in Coulomb systems, and dissociative ionisation. The individual chapters, each written by leading experts, give a concise picture of the advanced experimental and theoretical methods. The book also describes experimental methods such as recoil-ion momentum spectroscopy (RIMS), electron microscopy (REMI), and many-particle time-of-flight and imaging techniques. Theoretical approaches treated include the three-body Coulomb problem, R- and S-matrix as well as classical approaches, close-coupling methods, and density-functional theory.

Fuzzy Logic Approach to Visual Multi-object Tracking

December 2017 · Neurocomputing

In this paper, a novel fuzzy logic data association algorithm is proposed for online visual multi-object tracking. Firstly, in the proposed algorithm, in order to incorporate expert experience into the data association for the improvement of performance in multi-object tracking, a fuzzy inference system based on knowledge is designed by using a set of fuzzy if-then rules. Given the error and ... [Show full abstract] change of error of motion, shape and appearance models in the last prediction, these rules are used to determine the fuzzy membership degrees that can be used to substitute the association probabilities between the objects and the measurements (or detection responses). Secondly, in order to deal with the fragmented trajectories caused by long-term occlusions, a track-to-track association approach based on the fuzzy synthetic function is proposed, which can effectively stitch track fragments (tracklets). Because of this, the proposed algorithm has the advantage that it does require no assumption of statistical models of measurement noise and of object dynamics. The experiment results on several public data sets show the efficiency and the ability to minimize the number of fragment tracks of the proposed algorithm.

March 2010 · Bulletin of the Academy of Sciences of the USSR Division of Chemical Science

B3LYP/LANL2DZ calculations of two series of isomeric dinuclear copper chelates based on the tridentate dibasic salicylaldimines from aromatic and heterocyclic amines were performed. According to calculations, the complexes with N,N-or S,S-donor atoms in the exchange fragment are mainly characterized by ferromagnetic exchange, whereas the formation of O, O-bridging fragments leads to ...
