A computer implement method for domain adaptation. According to the method, training data from a target domain may be classified by using a group of source models of a source domain, where each of the source models is trained to classify data from the source domain. A first pseudo label indicating a category of the training data may be generated by aggregating classification results of the source models based on respective weights of the source models on predetermined data categories. A target model of the target domain may be trained based on the training data and the first pseudo label and the second pseudo label, where the target model is trained to classify data from the target domain.

The present disclosure relates to a method, system and computer program product for electronic health record (EHR) data synthetization. According to the method, an original EHR dataset X is captured. A latent space Z is generated from the original EHR dataset X, wherein dimensionality of Z is lower than that of X. A stochastic process prior module is applied to the latent space Z. Synthetic EHR dataset X' is reconstructed from the latent space Z after being applied with the stochastic process prior.

Aspects of the invention include a computer-implemented method including extracting a domain-specific object feature from a first image data, wherein the feature describes an object in the first image data. A domain-specific semantic meaning of text data is determined. The object feature is mapped to a portion of the text data, wherein the portion of the text data describes the object. A joint representation of the object and the portion of the text data is created. A second image data and a query directed towards an object in the second image data is received. An answer to the query is generated based on the joint representation.

Disclosed are methods for preparing high-purity boehmite and porous gamma-alumina nano-powder, comprising: adding aluminum isopropoxide into water and stirring the aluminum isopropoxide added water, then adding aluminum hydroxide generated by hydrolysis of high-purity aluminum powder into that stirred water, stirring that aluminum hydroxide added water to obtain a mixed system; carrying out hydrothermal reaction on the mixed system, performing centrifuging, washing, drying and crushing to the reacted mixed system, obtaining high-purity boehmite; calcining the high-purity boehmite to obtain porous gamma (&#x3b3;)-alumina nano-powder. By strictly controlling the addition of isopropanolic aluminum and the temperature as well as the duration of the hydrothermal reaction, the product boehmite &#x3b3;-AlOOH obtains good character in terms of crystalline structure, purity, morphology and dispersion; &#x3b3;-AlOobtained after calcining remains basically the same morphology as that of boehmite powder with good powder dispersion and no major changes.

A multiplex proteome quantification method based on isobaric dimethyl labeling implements dimethyl labeling of peptide N-terminal in an acidic condition and C-terminal in an alkaline condition one after another by means of Hall the property that a dimethylation reaction has different rates on an amino group at the peptide N-terminal and an amino group on a Lysine side chain at the peptide C-terminal in the acidic condition. Multiplex labeling of peptide samples is implemented by means of the organic combination of various isotope forms of a dimethyl labeling reagents. The mass-to-charge ratios in MS1 of peptides after multiplex labeling are completely the same, the mass-to-charge ratios of the fragment ions in MS2 are different, and multiplex quantitative analyses are carried out by extracting the intensity values of corresponding fragment ions in the MS2.
