Abstract: New analytical equations for litude analysis of MOS Hartley oscillator are presented. Using exact large-signal circuit analysis, analytical equations for estimating the litude of Hartley oscillator are derived that considers all operation regions of transistor including saturation, triode and cutoff. The analysis is based on a reasonable estimation for the output waveform. The estimated waveform should satisfy the nonlinear differential equations describing the circuit. Using this novel point, we can simply find the unknown parameters of the waveform, especially litude. The validity of the resulted equations is verified through simulations using TSMC 0.18 μm CMOS process. The litude calculated from this approach has a very good agreement with simulation for a large range of circuit parameters.

Abstract: Despite efforts to standardize histopathology practice through the development of guidelines, the interpretation of morphology is still h ered by subjectivity. We here describe Pathology Imagebase, a novel mechanism for establishing an international standard for the interpretation of pathology specimens. The International Society of Urological Pathology (ISUP) established a reference image database through the input of experts in the field. Three panels were formed, one each for prostate, urinary bladder and renal pathology, consisting of 24 international experts. Each of the panel members uploaded microphotographs of cases into a non-public database. The remaining 23 experts were asked to vote from a multiple-choice menu. Prior to and while voting, panel members were unable to access the results of voting by the other experts. When a consensus level of at least two-thirds or 16 votes was reached, cases were automatically transferred to the main database. Consensus was reached in a total of 287 cases across five projects on the grading of prostate, bladder and renal cancer and the classification of renal tumours and flat lesions of the bladder. The full database is available to all ISUP members at www.isupweb.org. Non-members may access a selected number of cases. It is anticipated that the database will assist pathologists in calibrating their grading, and will also promote consistency in the diagnosis of difficult cases.
