Abstract: To better understand the biology of hormone receptor-positive and negative breast cancer and to identify methylated gene markers of disease progression, a genome-wide methylation array analysis was performed on 103 primary invasive breast cancers and 21 normal breast samples using the Illumina Infinium HumanMethylation27 array that queried 27,578 CpG loci. Forty CpG loci showed differential methylation specific to either ER-positive or ER-negative tumors. Each of the 40 ER-subtype-specific loci was validated in silico using an independent, publicly available methylome dataset from The Cancer Genome Atlas (TCGA). In addition, 100 methylated CpG loci were identified that were significantly associated with disease progression. Arrays containing the ER-subtype-specific loci and their use in methods of diagnosis and treatment of breast cancer are provided.

Abstract: Technical solutions are described for preventing controller windup in a motor control system. An example system includes a first anti-windup module that receives a commanded voltage and a limited voltage command. The limited voltage command is applied to an electric motor, where the first anti-windup module generates a first modified current command by modifying a current command that is applied to the motor control system. The modification is based on a ratio of the commanded voltage and the limited voltage command. The system further includes a second anti-windup module that receives the commanded voltage and the limited voltage command. The second anti-windup module generates a second modified current command by modifying the first modified current command. The modification based on a difference between the commanded voltage and the limited voltage command.

Abstract: A speaker box includes a housing with an accommodating space and a housing wall; a propping wall extending from the housing wall toward the accommodating space; and a speaker unit located between the housing wall and the propping wall for dividing the accommodating space into a front cavity and a back cavity. The speaker unit includes a diaphragm located in the front cavity for forming a front sound cavity cooperatively with the housing, a sound guiding channel communicating the front sound cavity with outside, and a through hole penetrating the propping wall and communicating the sound guiding channel with the back cavity. The speaker box further includes an elastic cover plate covering the through hole completely for absorbing vibration energy at a specific frequency. The Young's modulus or strength of the elastic cover plate is smaller than that of the propping wall.

Abstract: A computer-implemented method generates a candidate answer triple for use in retrieving information used to answer a question. One or more processors parse a question to identify a lexical answer type for the question, a question action for the question, and a question timestamp for the question to make up a question triple. One or more processors retrieve multiple candidate passages for answering the question, and parse each of the multiple candidate passages to identify a candidate entity, a candidate action, and a candidate timestamp from each of the multiple candidate passages to generate a candidate answer triple. One or more processors compare the question triple to the candidate answer triple and establish a match score for each candidate answer triple, which is used in retrieving information used to answer the question.

Abstract: The current subject matter determines the location of the J-point in an ECG signal by examining ECG samples within a window of samples between the S-peak and the T-peak. The sample in this range with the smallest distance, ?d, to the R-peak is selected as the J-point. Thus, the J-point location can be determined based on an ECG sample's distance to the R-peak. The J-point location can then be used to determine whether there is elevation or depression of the ST segment. Related apparatus, systems, techniques, and articles are also described.
