Patterns of Student Help-Seeking When Using a Large Language Model-Powered Programming Assistant
Brad Sheese, Mark Liffiton, Jaromir Savelka +1
Providing personalized assistance at scale is a long-standing challenge for computing educators, but a new generation of tools powered by large language models (LLMs) offers immens…
On the complexity of inverse semigroup conjugacy
Trevor Jack
We investigate the computational complexity of various decision problems related to conjugacy in finite inverse semigroups. We describe polynomial-time algorithms for checking if t…
Carrier-Envelope-Phase Dependent Strong-Field Excitation
D. Chetty, R. D. Glover, X. M. Tong +9
We present a joint experimental-theoretical study on the effect of the carrier-envelope phase (CEP) of a few-cycle pulse on the atomic excitation process. We focus on the excitatio…
On the Solutions of Three Variable Frobenius Related Problems Using Order Reduction Approach
Tian-Xiao He, Peter J. -S. Shiue, Rama Venkat
This paper presents a new approach to determine the number of solutions of three variable Frobenius related problems and to find their solutions by using order reducing methods. He…
Observation of Dynamic Stark Resonances in Strong-Field Excitation
Dashavir Chetty, Rohan D. Glover, Bruno A. deHarak +12
We investigate AC Stark-shifted resonances in argon with ultrashort near-infrared pulses. Using 30 fs pulses we observe periodic enhancements of the excitation yield in the intensi…
-sequences, -sequence, and -sequences of Riordan Matrices
Tian-Xiao He
We defined two type -sequences of Riordan arrays and present the -sequence characterization and -sequence characterization of the Riordan matrices with two type -sequen…
