The first pressurizing plate surface presses an electronic element located on a first circuit board surface of a circuit board. The pressurizing device includes a plurality of peripheral pressurizing units applying pressure to a peripheral region of the second pressurizing plate surface and a plurality of central pressurizing units applying pressure to a central region of the second pressurizing plate surface.

Abstract: Disclosed are an anchoring device and an anchoring apparatus. The anchoring device includes a coupling member and two anchoring members. The two anchoring members are arranged on the coupling member at intervals in a first direction. A dimension of the anchoring member in a second direction is a first dimension, the second direction is perpendicular to the first direction. The anchoring member is configured to switch between a first configuration and a second configuration. When the anchoring member is in the first configuration, a dimension of the anchoring member in a direction perpendicular to the first direction is a second dimension. When the anchoring member is in the second configuration, a dimension of the anchoring member in the second direction is a third dimension, and the third dimension is greater than the second dimension and the first dimension.

Abstract: Aspects of the disclosure are directed to methods, systems, and computer readable media for adaptation with self-evaluation to improve selective prediction in large language models (LLMs), generally referred to as ASPIRE. ASPIRE includes training LLMs on a portion of training data from a question answering task to learn self-evaluation, e.g., learn to distinguish whether a generated answer is correct or not. ASPIRE further includes a selection score that combines a likelihood of that generated answer is correct with a self-evaluation score for selective prediction. ASPIRE demonstrates improved selective prediction performance with less computational cost.

Abstract: Aspects of the present disclosure include a robotic wheel that includes a tensegrity structure, an inner hub, an outer hub, and a cable. The tensegrity structure includes multiple rigid rods and multiple elastic cables, and the tensegrity structure defines a longitudinal axis, a first end and a second end. The inner hub is disposed at the first end of the tensegrity structure and the outer hub is disposed at the second end of the tensegrity structure. The cable is in contact with the outer hub, extends through the tensegrity structure parallel to the longitudinal axis, and extends through the inner hub. The cable is operable to retract to transition the tensegrity structure to a collapsed state and to extend to transition the tensegrity structure an expanded state.

Abstract: The present disclosure provides a camera module, an information processing method, and an electronic device. The camera module includes a casing and a lens assembly movably connected to the casing. The lens assembly includes a lens group including a plurality of lenses, and the lens group is fixedly arranged in a lens barrel. The camera module further includes a sensor assembly movably connected to the casing. The sensor assembly is located under the lens assembly. The camera module also includes a driving assembly, which drives the lens assembly and/or the sensor assembly to move based on a control signal.

Abstract: A slide slot type multi-arm clamp includes a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, a surgical operator applies an axial thrust and a pulling force to the handle to drive the control line to move, so as to open/close and lock the clamping portion. Moreover, side clamp arms and a clamp base in the clamping portion can be easily separated from the catheter or the spring tube to stay in a human body so as to achieve the functions of hemostasis and tissue suture. The side slot type multi-arm clamp can achieve the effect of minimizing the length of the instrument retained in the human body by the cooperation between the side clamp arms and the clamp base.
