  • Publication number: 20250071988
    Abstract: A memory device includes a first-tier structure including a first first-tier alternating stack and a second first-tier alternating stack, a second-tier structure overlying or underlying the first-tier structure and including a first second-tier alternating stack and a second second-tier alternating stack that are laterally spaced apart from each other by a jumper alternating stack, and memory stack structures vertically extending through a respective set of at least two alternating stacks. Each of alternating stack includes a respective vertically alternating sequence of insulating layers and electrically conductive layers.

  • Publication number: 20250071998
    Abstract: A memory device includes source-level material layers containing a lower source-level semiconductor layer, a source contact layer, and an upper source-level semiconductor layer, an alternating stack of insulating layers and electrically conductive layers located over the source-level material layers, a memory opening vertically extending through the alternating stack and into an upper portion of the source-level material layers, and a memory opening fill structure located in the memory opening and including a memory film and a vertical semiconductor channel. The source contact layer includes a horizontally-extending portion and a vertically-extending portion having a greater vertical extent than the horizontally-extending portion, having an inner cylindrical sidewall contacting a bottom portion of the vertical semiconductor channel, and contacting a bottommost insulating layer within the alternating stack.

  • Patent number: 9631014
    Abstract: Disclosed is a method of diagnosing graft-versus-host disease, comprising measuring the level of CCL8 protein in a sample obtained from a subject as an indicator for the diagnosis or course of graft-versus-host disease. Also a diagnostic reagent for graft-versus-host disease comprising an anti-CCL8 antibody is disclosed. The method of the present invention enables diagnosis of the onset of graft-versus-host disease and monitoring of the progress, in particular, differential diagnosis between graft-versus-host disease and an infectious disease. The present invention also provides a method for treating graft-versus-host disease utilizing the anti-CCL8 antibody.

  • Patent number: 6678574
    Abstract: A method for producing suspension parts via preforming the workpiece by roll forming. The sectional area and length of the workpiece are calculated. In the former step, more than one orthogonal cross-section is acquired from the suspension part of aluminum alloy, and the sectional area is converted into the area of a circle. An imaginary area is calculated by adding to the converted area an adequate amount of flash. In the latter step, a circular truncated cone is defined from two adjacent imaginary circles and the length of the imaginary center line between the two adjacent imaginary circles. A solid of revolution is defined by connecting these circular truncated cones, and the volume of the suspension part of aluminum alloy is substituted by the volume of the solid of revolution. The value obtained by dividing the sectional area of the workpiece by the volume is regarded as the-length of the workpiece.
