Publication number: 20240161867Abstract: One or more techniques for optimizing cancer classification based on covariate characteristics is disclosed. In a first approach, an analytics system may determine separate cutoff thresholds for positively detecting disease signal for different labels for a covariate characteristic. The system may subdivide training samples based on their labels for the covariate characteristic, to separately determine the cutoff thresholds. In other approaches, the system may train disparate classifiers for each population. The system separates the training samples based on their labels for the covariate characteristic, and separately trains classifiers to generate a signal vector representing an amount of disease signal detected in a sample. The classifiers may be trained on different feature sets as determined based on mutual information gain, genomic region coverage, and healthy activation fraction.Type: ApplicationFiled: November 16, 2023Publication date: May 16, 2024Inventors: Alexander P. Fields, John F. Beausang, Oliver Claude Venn, Arash Jamshidi, M. Cyrus Maher, Qinwen Liu, Jan Schellenberger, Joshua Newman, Robert Abe Paine Calef, Samuel S. Gross, Frank Chu, Earl Hubbell

Patent number: 4486813Abstract: An activator composition paste includes a homogeneous dispersion of a palladium and commensurate amounts of silicon and of zinc. A screen printed layer of this paste is applied to a ceramic capacitor body to form electrodes, terminations or both. The body is heated to 615.degree. C. and subsequently electroless nickel plated providing excellent electrical and mechanical connection of the plated nickel to the ceramic.Type: GrantFiled: December 12, 1983Date of Patent: December 4, 1984Assignee: Sprague Electric CompanyInventor: John P. Maher

Patent number: 4230754Abstract: An electronic component with leads attached is cleaned, a layer of an epoxy or epoxy-reactive silane is applied and cured, and then the package material is molded on. The silane layer bonds the component to the package and provides a fluid-tight seal therebetween. The silane is gamma-glycidoxypropyl- or gamma-aminopropyltrimethoxy or triethoxy silane.Type: GrantFiled: November 7, 1978Date of Patent: October 28, 1980Assignee: Sprague Electric CompanyInventors: John P. Maher, Elsa Kam-Lum

Patent number: 4192698Abstract: A smooth electroding ink containing a silver-alloy powder is prepared by milling and deagglomerating the silver-alloy powder in the same vehicle employed in the ink. This is accomplished at high production rates in a sand mill by establishing and maintaining during milling a splash-free laminar-flow vortex of the slurry, leading to very smooth buried silver-alloy electrode films in a monolithic ceramic capacitor.Type: GrantFiled: September 7, 1977Date of Patent: March 11, 1980Assignee: Sprague Electric CompanyInventors: John P. Maher, Robert T. Jacobsen

Patent number: 4107762Abstract: A fuse for a solid electrolyte capacitor is made of two exothermically alloyable metals such as aluminum and palladium. The fuse has a series electrical connection with and a thermal connection to the capacitor body. A defective and overheated capacitor section results in abnormally high currents so that the fuse temperature is elevated by ohmic self-heating and/or by the flow of heat from the overheated body. When the alloying temperature of the fuse is reached, the temperature of the alloying fuse momentarily becomes very high and opens essentially along its entire length.Type: GrantFiled: May 16, 1977Date of Patent: August 15, 1978Assignee: Sprague Electric CompanyInventors: George A. Shirn, John P. Maher

Patent number: 4107759Abstract: A fuse for a monolithic ceramic capacitor is made of two exothermically alloyable materials such as aluminum and palladium. A monolithic ceramic body has two conventional conductive layer terminals contacting two groups of buried film electrodes. The body also has a third conductive layer that is spaced from the conventional terminals and the electrodes. A fuse is connected between a conventional terminal and the third layer. Alternatively, the conventional body without the third layer has two leads, one of which is connected to a first of the terminals and the other of which is insulated from both terminals but physically attached to the body. In this case the fuse is connected between the insulated of the leads and the second of the terminals.Type: GrantFiled: May 16, 1977Date of Patent: August 15, 1978Assignee: Sprague Electric CompanyInventors: George A. Shirn, John P. Maher

Patent number: 4104421Abstract: A cermet resistor employs film terminations of sub-micron thickness. The terminations contain particles of SiO.sub.2 or MnO.sub.2 that may be conveniently made by mixing such particles in a metal resinate paste, screening the paste on a glazed or unglazed substrate and firing. A glass containing resistor paste is screened in overlapping relationship with the fired terminations and is itself fired. The particle additives ameliorate cracking of the terminations at resistor firing and enhance the termination to substrate bond.Type: GrantFiled: August 3, 1976Date of Patent: August 1, 1978Assignee: Sprague Electric CompanyInventors: John P. Maher, Theodore W. Johnson

Patent number: 4053864Abstract: A PTCR thermistor has a doped barium titanate body, and two base metal lead wires being bonded to and ohmically connected to two separate surface regions of the body by means of two conductive electrodes, respectively. The electrodes are comprised of aluminum particles being bound within a matrix of a lead borate glass. The glass amounts to from 20 to 60% by weight. The simple method of making the thermistor may include the selective application of heat to the electrode regions to avoid oxidizing the base metal leads. These thermistors are capable of undergoing many self-heating switching operations in service without deterioration of the lead to body connections.Type: GrantFiled: December 20, 1976Date of Patent: October 11, 1977Assignee: Sprague Electric CompanyInventors: George H. Rodriguez, John P. Maher

Patent number: 3989874Abstract: In a noble-metal containing resistor paste, there is added a quantity of colloidal aluminum oxide hydroxide (AlOOH) in order to make an upward adjustment in the TCR of the fired resistor film. The additions of AlOOH have only a small effect on the resistivity and usually causes a downward change in the resistivity value.Type: GrantFiled: January 23, 1975Date of Patent: November 2, 1976Assignee: Sprague Electric CompanyInventor: John P.
