Abstract:
Forward modeling is performed to compute a response of a target structure, the forward modeling accounting for distortion of a reflected signal from a reflector in the target structure. Waveform inversion is performed using the response of the forward modeling.
Abstract:
There is provided compounds of formula I, wherein R1, R2, R3, R4, R41 to R46, A, B and G have meanings given in the description, which are useful in the prophylaxis and in the treatment of arrhythmias, in particular atrial and ventricular arrhythmias.
Abstract:
There is provided a method of direct waveform inversion of turning waves (311, 312, 313) to determine parameters characterizing properties of the earth or sub-sections of the earth, particularly of parts of the earth which are capable of trapping hydrocarbons with the inversion yielding from the wavefield of turning waves information representing or being equivalent to velocities or slownesses and/or the gradient of velocities or slownesses, particularly by evaluating wavefield data in the vicinity of turning points (33). The method can be applied sequentially as a survey sinking method.
Abstract:
The invention relates to compounds of formula (X), and salts thereof, and their use as intermediates in improved manufacturing processes for the synthesis of pharmaceutical compound (I): X is ═O, ═N—OH or ═N—OC(O)Me; Y is hydrogen, PhS- or p-chlorophenylsulfanyl; Z is hydrogen or —CH2COOR1 wherein R1 is selected from hydrogen, optionally substituted hydrocarbyl and optionally substituted heterocyclyl.

A method for the preparation of a compound of formula (1) or a pharmaceutically acceptable salt or solvate thereof; from a compound of the formula: (IV); wherein L represents a leaving group.
Abstract:
Process for the preparation of 2-(2,4-dichlorophenoxy)phenylacetic acid in which the potassium salts of 2-chlorophenylacetic acid and 2,4-dichlorophenol are reacted in aromatic hydrocarbon solvents at elevated temperatures in the presence of a copper chloride catalyst, followed thereafter by acidification.
