Abstract: A new set of bench-stable fluoroalkylphosphines that directly convert C—H bonds in pyridine building blocks, drug-like fragments, and pharmaceuticals, into fluoroalkyl derivatives. No pre-installed functional groups or directing motifs are required. The reaction tolerates a variety of sterically and electronically distinct pyridines and is exclusively selective for the 4-position in most cases. The reaction proceeds via initial phosphonium salt formation followed by sp2-sp3 phosphorus ligand-coupling, an underdeveloped manifold for C—C bond formation.

Abstract: An adjustment device and associated method is disclosed, for adjusting an equipment, such as a camera, having an actuator for adjusting a variable setting, such as a lens setting (focus, iris, zoom). A control system drives the actuator and command component of the adjustment device to reflect a position of the actuator. In a slave mode, the command component is driven by the control system. In an override mode, a manual operation of the command component drives the actuator of the equipment. Also disclosed are a method for building a model of a lens, a method for treating an image capture to produce a visual effect, a method for creating a node in a model representing a given space, a method for setting a node in a model based on a known node, and a method for calibrating a node in a model.

Abstract: A method and system for controlling a setting of an equipment related to image capture comprises capturing position data and orientation data of a sensing device; determining position information of a region of interest (i.e. a node) to be treated by the equipment, relative to the position and orientation data of the sensing device; and outputting a control signal directed to the equipment, in order to control in real-time the setting of the equipment based on said position information of the region of interest.

Abstract: A computing device may compute the hospital admission risk of a patient as of a first risk calculation date after provision of one or more interventions for the patient. Each such intervention may be of a type that can readily be provided without bringing the patient to a hospital. According to one method, an input device may be used to receive first user input indicative of a first intervention performed for the patient. From a data store, a first risk factor corresponding to the first intervention, and a first time period over which the first risk factor is applicable, may be retrieved. At a processor, a first intervention date may be compared with the first risk calculation date to determine that the first risk calculation date is within the first time period. The first risk factor may be used to compute and display the hospital admission risk for the patient.

Abstract: An electric device operable with a THz-range frequency of the device output is presented. The device comprises a photocathode installed in either one of a diode, triode and tetrode configuration, and is exposed to illumination. In some embodiments of the invention, the device is configured as a diode and photomixing is used for illumination of the photocathode with light in the THz range, the diode converting this input light signal into an electrical output in the THz range, which operates a signal transmitter/receiver.
