  • Publication number: 20250051951
    Abstract: A method of plating substrates may include placing a substrate in a plating chamber comprising a liquid, and applying a current to the liquid in the plating chamber to deposit a metal on exposed portions of the substrate, where the current may include alternating cycles of a forward plating current and a reverse deplating current. To determine the current characteristics, a model of a substrate may be simulated during the plating process to generate data points that relate characteristics of the plating process and a pattern on the substrate to a range nonuniformity of material formed on the substrate during the plating process. Using information from the data points, values for the forward and reverse currents may be derived and provided to the plating chamber to execute the plating process.

  • Patent number: 12218081
    Abstract: Microelectronic devices include a stack structure of insulative structures vertically alternating with conductive structures and arranged in tiers forming opposing staircase structures. A polysilicon fill material substantially fills an opening (e.g., a high-aspect-ratio opening) between the opposing staircase structures. The polysilicon fill material may have non-compressive stress such that the stack structure may be partitioned into blocks without the blocks bending and without contacts—formed in at least one of the polysilicon fill material and the stack structure—deforming, misaligning, or forming electrical shorts with neighboring contacts.

  • Patent number: 12205440
    Abstract: Rather than typical slot type games where specific matching combinations of symbols along paylines through a row-by-column grid or matrix indicate the outcome of the game, a slot type concatenation game concatenates value symbols along a payline to form a numerical outcome. Non-value symbols may be omitted and/or ignored. Further, the payline may be indicated by the presence of a trigger symbol, which may allow the payline to change between different plays of the slot type concatenation game. Further, the slot type concatenation game may be user-configurable. Users may be allowed to indicate the number of the symbol reels that may include value symbols that will be concatenated along a payline defined by the trigger symbol. Users may be allowed indicate the denomination set that is used to configure the symbol reels with value symbols, such as from one or more value symbol tables.

  • Patent number: 11619005
    Abstract: A seamed press felt formed from a base fabric having a CD width and an MD length with two opposing MD ends that are joined to form a continuous belt. MD oriented yarns form uniform loops at the two opposing MD ends that are interdigitated to define a pintle channel extending across the CD width. CD oriented yarns are connected to the MD oriented yarns, in a woven or non-woven construction. Loop open spaces are located within the loops on each of the two opposing MD ends in a seam region, with the loop open spaces being defined between a last one of the CD yarns at each of the two opposing MD ends and the pintle channel. At least one CD monofilament support yarn is located in the loop open spaces on each of the two opposing MD ends. The at least one CD monofilament support yarn has a diameter that is at least 1.6 times a diameter of the CD oriented yarns. A pintle extends through the pintle channel to form a seam.

  • Publication number: 20220333108
    Abstract: Compositions and methods are provided for silencing the Sulf2 and/or GPC3 genes in vivo. Potent siRNA sequences are provided that silence regions of the Sulf2 and GPC3 genes that are identical in human, mice and non-human primates. Combinations of siRNAs also are provided that result in additivity or synergy with silencing of Sulf2 and/or GPC3. Silencing SULF2+TGF?1 showed a dramatic effect against cancer growth in vitro and in vivo.

  • Publication number: 20140243265
    Abstract: High-specificity antibodies can distinguish between modified (e.g, hIGF-1/Ea 3mut) and endogenous wild-type human IGF-1 proteins. These antibodies have little or no cross-reactivity with hIGF-1 or hIGF-2. They also have little or no cross-reactivity with rodent IGF-1 or IGF-2. The antibodies can be used in pharmacokinetic (PK)/pharamcodynamic (PD) assessments of IGF-1/E peptides that have been administered to humans or animals. A sandwich ELISA assay, using the antibody of the invention as a capture antibody, can quantify the mutant IGF-1/E proteins in samples.
