Abstract: An experimental device and method for supercritical CO2/H2O mixed fluid huff and puff for shale oil development includes a CO2 storage tank, a water vapor generator, a mixing vessel, and a core holder; the CO2 storage tank and the water vapor generator are in communication with the mixing vessel; a first pressure gauge and a hygronom are connected to an upper end of the mixing vessel, and a displacement pump is connected to a lower end of the mixing vessel; the mixing vessel is connected to an inlet end of the core holder; the core holder is connected to an inlet end of a drying pipe, and the measuring cylinder is disposed upside down in a liquid containing dish, where the liquid containing dish and the measuring cylinder are filled with a saturated sodium carbonate solution.

Abstract: Disclosed herein is a method for detecting deletion in a gene sequence. The method comprises receiving, by a processor, training sequencing data, which comprises multiple training reads associated with gene sequences with deletion and gene sequences without deletion. The processor splits each of the multiple training reads into multiple training segments shorter than the training reads and trains a machine learning model on the multiple segments. The processor receives testing sequencing data comprising multiple testing reads, splits each of the multiple testing reads into multiple testing segments, and evaluates the trained machine learning model to the multiple testing segments to detect deletion in the testing sequencing data. No alignment or variant calling is necessary, which reduces the computational complexity of the evaluation step significantly.

Abstract: A golf club head includes a golf club head body and a weight member. The golf club head member has a recession in which the weight member is mounted. The weight member is securely mounted in the recession of the golf club head body by a welding procedure that uses a welding material. The weight member is made of a material having a melting point higher than that of the golf club head body, avoiding melting of the weight member during the welding procedure. Only a portion of the golf club head body fuses with the welding material while using the welding material for proceeding with the welding procedure for the weight member.

Abstract: A weight member for a golf club head is made of a WFeNi alloy by a precision casting process. The WFeNi alloy includes wt 15%-40% of iron, wt 30%-60% of nickel, wt 15%-30% of tungsten, wt 1.5%-10.0% of chromium, and wt 0.5%-5.0% of molybdenum. Chromium improves the rust-resisting property of the weight member. Molybdenum reduces the risk of cracks in the weight member during welding. Uniformity of shining finishing of the weight member can be improved by controlling a mixture ratio of nickel to tungsten. Manganese, copper, vanadium, and niobium may be added to improve the mechanical properties of the weight member.

Abstract: A weight member for a golf club head is made of a WFeNi alloy by a precision casting process. The WFeNi alloy includes nickel 30-60 wt %, tungsten 15-30 wt %, chromium 1.5-10.0 wt %, and iron that is the remaining portion. Chromium improves the rust resisting property of the weight member and lengthens the life of the weight member. Uniformity of shining finishing of the weight member can be improved by controlling a mixture ratio of nickel to tungsten. Silicon may be added to improve the flowability of the molten metal. Manganese, copper, vanadium, and niobium may be added to improve the mechanical properties of the weight member.
