Abstract: A computer-based method for finding a compatible partner for a user includes: determining one or more of a birth card (BC) of the user and a planetary ruling card (PRC) of the user; if a desired connection is a friendship connection or a romantic connection, representing one or more of the user's BC and the user's PRC as Mi,j, where i and j are indices of one or more of a spiritual spread of the user and a life spread of the user: representing with blank cards birth cards that have diagonal element indices that fall outside a spread; removing the blank cards; using remaining elements, computing remaining compatible diagonal elements; and adding the compatible diagonal elements to the compatible cards array, so as to compute compatible diagonal elements for one or more of the user's BC and the user's PRC.

Abstract: One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. The one or more medical devices may include a laparoscopic sleeve gastrectomy stapling guide in conjunction with a calibration tube in accordance with one or more examples. According to an example, the calibration tube may be a flared, multi-diameter calibration tube. The flared, multi-diameter calibration tube may have a first diameter along a portion of the tube and a second diameter that may larger than the first diameter along at least another portion of the tube. The calibration tube may be used in conjunction with the stapling guide to align stomach such that it may be stapled along the stapling guide (e.g., to perform the vertical sleeve gastrectomy).
