Synthesis of nested loop exercises for practice in introductory programming

Egyptian Informatics Journal, 2023
Novice programmers struggle to comprehend specific programming constructs such as arrays, recursion, and loops. One way to address this challenge is to provide practice problems for students in these topics that are considered difficult to comprehend ...

Darboux transformation with dihedral reduction group [PDF]

, 2014
We construct the Darboux transformation with Dihedral reduction group for the 2-dimensional generalisation of the periodic Volterra lattice. The resulting Bäcklund transformation can be viewed as a nonevolutionary integrable differential difference ...

Eigenvalue-eigenfunction problem for Steklov's smoothing operator and differential-difference equations of mixed type [PDF]

Opuscula Mathematica, 2013
It is shown that any \(\mu \in \mathbb{C}\) is an infinite multiplicity eigenvalue of the Steklov smoothing operator \(S_h\) acting on the space \(L^1_{loc}(\mathbb{R})\).

A proposal of a Renormalization Group transformation [PDF]

, 1994
We propose a family of renormalization group transformations characterized by free parameters that may be tuned in order to reduce the truncation effects. As a check we test them in the three dimensional XY model.

A scoping review on the factors associated with the lost to follow-up (LTFU) amongst patients with chronic disease in ambulatory care of high-income countries (HIC)

BMC Health Services Research, 2023
Background Despite the importance of long term follow-up care for patients with chronic disease, many patients fail to adhere to their follow-ups, which increase their risk of further health complications.

Pseudoduality in Sigma Models [PDF]

, 2002
We revisit classical "on shell" duality, i.e., pseudoduality, in two dimensional conformally invariant classical sigma models and find some new interesting results.

Spacetime Ehlers group: Transformation law for the Weyl tensor [PDF]

, 2001
The spacetime Ehlers group, which is a symmetry of the Einstein vacuum field equations for strictly stationary spacetimes, is defined and analyzed in a purely spacetime context (without invoking the projection formalism).
