Periodic 2-graphs arising from subshifts [PDF]
, 2009 Higher-rank graphs were introduced by Kumjian and Pask to provide models for higher-rank Cuntz-Krieger algebras. In a previous paper, we constructed 2-graphs whose path spaces are rank-two subshifts of finite type, and showed that this construction ...

Ionescu's theorem for higher rank graphs [PDF]
Indiana University Mathematics Journal, 2015 We will define new constructions similar to the graph systems of correspondences described by Deaconu et al. We will use these to prove a version of Ionescu's theorem for higher rank graphs. Afterwards we will examine the properties of these constructions further and make contact with Yeend's topological k-graphs and the tensor groupoid valued product ...

Fibers add flavor. Part I. Classification of 5d SCFTs, flavor symmetries and BPS states
Journal of High Energy Physics, 2019 We propose a graph-based approach to 5d superconformal field theories (SCFTs) based on their realization as M-theory compactifications on singular elliptic Calabi-Yau threefolds.

BPS graphs: from spectral networks to BPS quivers
Journal of High Energy Physics, 2017 We define “BPS graphs” on punctured Riemann surfaces associated with A N −1 theories of class S $$ \mathcal{S} $$ . BPS graphs provide a bridge between two powerful frameworks for studying the spectrum of BPS states: spectral networks and BPS quivers ...

Graphs Regularized Robust Matrix Factorization and Its Application on Student Grade Prediction
Applied Sciences, 2020 Student grade prediction (SGP) is an important educational problem for designing personalized strategies of teaching and learning. Many studies adopt the technique of matrix factorization (MF).

The Influence of COVID-19 on Influenza and Respiratory Syncytial Virus Activities
Infectious Disease Reports, 2022 Background: Respiratory viral diseases have considerably declined since the COVID-19 outbreak, perhaps through influence by nonpharmaceutical interventions. We conducted a cross-sectional study using the CDC database to compare the pre- vs. post-pandemic

Seasonal Analysis of Reference Evapotranspiration and Its Sensitivity to Meteorological Elements in IRAN [PDF]
مجله آب و خاک, 2023 IntroductionEvapotranspiration is the combination of two separate processes, soil moisture evaporation, and plant transpiration, which amount depends on various meteorological elements. Therefore, identifying the effective factors and the amount of their
