The invention relates to a system for assessing chloride concentration at one predetermined area of a porous or composite material, such as a reinforced concrete structure, comprising a sensor (1) embedded in the predetermined area of the material, an analyser (2) connected to the sensor, and a processing module (4) connected to the analyser. The sensor (1) comprises two facing or coplanar electrodes (11), called electrodes, an intermediate layer (13) arranged between said electrodes, said intermediate layer being in contact with the material of the first area of the structure and comprising calcium aluminates. The analyser (2) is configured to apply an alternate current between the electrodes and output an impedance value or capacitance value of the intermediate layer. The processing module (4) is configured to compute a chloride concentration assessment in the predetermined area of the material based on the impedance value or capacitance value outputted by the analyser.

The present invention relates to a method and a device for encoding a current frame of a video sequence, said current frame being encoded block by block. According to the invention, a current block of the current frame is encoded by performing the following steps:- applying (S1) a texture synthesis to said video sequence in order to generate a set of n candidate blocks for replacing the current block, said n candidates blocks. being similar to the current block according to a predefined criterion,- encoding (S3) the candidate blocks in order to generate encoded candidate blocks and computing a coding cost for each encoded candidate block, and- selecting (S4) as encoded block for the current block the encoded candidate block having the lowest coding cost.

The present invention relates to methods for determining whether a patient will achieve a response after radiation therapy. In particular, the present invention relates to a method for determining whether a patient suffering from a cancer will achieve a response after radiation therapy comprising the steps of i) determining the level of ceramide in a first blood sample obtained from the patient before radiation therapy, ii) determining the level of ceramide in a second blood sample obtained from the patient during or just after radiation therapy, iii) comparing the level determined at step i) with the level determined at step ii) and iv) concluding that the patient will achieve response when the level determined at step ii) is higher than the level determined at step i) or concluding that the patient will not achieve a response when the level determined at step ii) is lower than the level determined at step i).
