Abstract: A cascaded impulse convolution shaping method for a nuclear signal includes: obtaining a detector signal by using a detector; convolving the detector signal with a Gaussian signal by using a multistage cascaded shaping system; and performing double-exponential impulse shaping, and generating, by using the multistage cascaded shaping system, a Gaussian-shaped impulse signal with a narrow pulse width for analysis. Based on the characteristic that a multistage cascaded convolution of a complex system can exchange a convolution sequence, the detector signal can first pass through a cascaded inverse system to form an impulse signal, and then the impulse signal is convolved with the Gaussian signal to generate a cascaded impulse convolution signal. This method can be extended to a three-exponential or four-exponential signal for Gaussian, trapezoidal, cyclotron up-scattering process (CUSP), cosine-squared distribution, and Cauchy distribution shaping.

Abstract: A set of conditions is defined that to be simulated via execution of a machine-learning model. For each condition, a set of learnable condition-specific parameters is identified to configure a model architecture. A first learnable condition-specific parameter associated with a first condition of the set of conditions can be identified a shared or global parameter that is to have a same value as at least another learnable condition-specific parameter (associated with another condition). One or more parameter data structures can be configured with parameter values for the sets of condition-specific parameters for the sets of conditions, where the configuration imposes a constraint that a value for the first condition-specific parameter and the at least one value for the at least one other condition-specific parameter are the same. The machine-learning model can be trained using the configured parameter data structure(s).

Abstract: A method of calibrating a collimating lens system includes transmitting, using an optical transmitter, a beam out of an optical fiber and through a collimating lens of the collimating lens system. The beam is reflected off a perfect flat mirror positioned at an output of the collimating lens and back towards the collimating lens, and received, via the collimating lens, at a power meter connected to the optical fiber. The method also includes adjusting a position of a tip of the optical fiber proximal to the collimating lens while tracking a power reading using the power meter, selecting a calibration position of the optical fiber corresponding to a highest power reading, and securing the optical fiber relative to the collimating lens using the calibration position.
