摘要:
An improved method is described for making 9-deoxy-PGF1-type compounds. In contrast to the prior art, the method is stereoselective and requires fewer steps than the known methods for making these compounds. The invention also relates to novel intermediates prepared during the synthesis of the 9-deoxy-PGF1-type compounds.

1&agr;,24(S)-Dihydroxy vitamin D2 which is useful as an active compound of pharmaceutical compositions for the treatment of disorders of calcium metabolism and for various skin disorders. The invention also includes preparation of synthetic 1&agr;,24(S)-dihydroxy vitamin D2 starting from ergosterol which is converted in six steps to 24-hydroxyergosterol. 24-Hydroxyergosterol is irradiated and thermally converted to 24-hydroxy vitamin D2 which is converted in six steps to 1&agr;,24(S)-dihydroxy vitamin D2. The syntheses also produced novel intermediates.

An herbal distillation device includes a herb chamber with perforated holes for holding herbs and a closed heated boiling chamber with openings at the side for a steam outlet. The herbal distillation device further includes an electric air-cooled condensation chamber which connects to the boiling chamber.
摘要:
A computer system can perform a semi-supervised machine learning processes to cluster a plurality of entities within a population based on their features and associated labels. The computer system can generate visualization data representing the clusters of entities and associated labels for displaying on a user interface. A user can review the clustering of entities and use the user interface to add or modify the labels associated with a particular entity or set of entities. The computer system can use the user's feedback to update the labels and then re-determine the clustering of entities using the semi-supervised machine learning process with the updated labels as input. As such, the computer system can use the user's feedback to improve the accuracy of the machine learning model without requiring a larger amount of labeled input data.

摘要:
A printed circuit board includes a mounting area. The mounting area includes a first mounting portion and a second mounting portion. The first and second mounting portions partially overlap. The first mounting portion includes a number of first holes, a number of second holes, and a third hole. The first holes, the second holes, and the third hole are configured for the mounting of signal pins of a universal serial bus (USB) pin. The second mounting portion includes the first holes and a number of fixing holes. The first holes are configured for the mounting of signal pins of a USB connector. The fixing holes are configured for the mounting of fixing pins of the USB connector.
