Abstract: A method for treating various types of cancer/tumor by administering the combination of SDF-1 antagonist, in particular, that specifically binds to human CXCR4, and another chemotherapeutic agent, or a radiation therapy, during an embolization therapy. Such combination therapies exhibit synergistic effects compared to the treatment with either agent alone. Thus, the method is particularly beneficial for cancer patients who have low tolerance to the side effects caused by high dosages required for the treatment by either agent alone.

Abstract: Systems and techniques are described for performing circuit synthesis. Some embodiments create a lookup table based on information contained in a cell library. The lookup table is then used during circuit synthesis. Specifically, some embodiments optimize cells in a reverse-levelized cell ordering. For a given cell, a table lookup is performed to obtain a set of optimal cell configurations, and the cell is replaced with a cell configuration selected from the set of optimal cell configurations. Some embodiments concurrently optimize cells for timing, area, and power leakage based on the timing criticality of the cells.

Abstract: A detailed placement process which optimizes cell placement with up to one hundred percent densities in a linear run time. The output from a conjugate-gradient coarse placement process is input to the detailed placement process. A dynamic programming technique is used to optimize cell placement by swapping cells between two or more rows. The search space is pruned beforehand. A greedy cleanup phase using an incremental row placer is used. Thereby, the detailed placement process handles congestion driven placements characterized by non-uniform densities expeditiously and efficiently.

Abstract: A holding device is presented in which a layer which is to be oxidized is processed, in a single-substrate process. The process temperature during the processing is recorded directly at the substrate or at a holding device for the substrate. The process includes introducing a substrate, which bears a layer to be oxidized uncovered in an edge region in a layer stack, into a heating device, passing an oxidation gas onto the substrate, heating the substrate to a process temperature, which is recorded during the processing via a temperature of the holding device which holds the substrate, and controlling the substrate temperature to a desired temperature or temperature curve during the processing.
