Discrete Minimal Surface Algebras

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
We consider discrete minimal surface algebras (DMSA) as generalized noncommutative analogues of minimal surfaces in higher dimensional spheres. These algebras appear naturally in membrane theory, where sequences of their representations are used as a ...

Assessing Capability Complexity Using Enterprise Architecture Framework

open access: yesSystems Engineering, EarlyView.
ABSTRACT This study proposes a structured and quantitative methodology to evaluate the holistic complexity of system‐of‐systems (SoSs), employing the Zachman Architecture Framework (ZAF) as its foundational analytical tool. A five‐phase analytical procedure is developed and empirically validated, encompassing: (1) refinement of complexity measures, (2)

Gause Symmetry and Howe Duality in 4D Conformal Field Theory Models

open access: yesActa Polytechnica, 2010
It is known that there are no local scalar Lie fields in more than two dimensions. Bilocal fields, however, which naturally arise in conformal operator product expansions, do generate infinite Lie algebras.

A Universal Meta‐Heuristic Framework for Influence Maximisation in Hypergraphs

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Influence maximisation (IM) aims to select a small number of nodes that are able to maximise their influence in a network and covers a wide range of applications. Despite numerous attempts to provide effective solutions in simple networks, higher‐order interactions between entities in various real‐world systems are usually not taken into ...

A Data‐Driven Multidimensional Profiling Framework for Residential Electricity Users With Application to Load Forecasting

open access: yesEnergy Internet, EarlyView.
ABSTRACT With the advancement of smart grid and Internet of Things, alongside broad adoption of distributed energy resources, precise profiling of residential users has become vital to grid operational efficiency and load forecasting accuracy. However, existing profiling approaches mainly rely on single‐source load data and fail to capture the dynamic ...

Time‐resolved XPCS analysis across broad time‐scales using multi‐tau two‐time correlations

open access: yesJournal of Synchrotron Radiation, EarlyView.
A scalable multi‐tau two‐time correlation framework enables efficient, time‐resolved XPCS analysis of long duration high‐frame‐rate modern synchrotron data while preserving sensitivity to non‐stationary dynamics.We present a multi‐tau two‐time correlation (MT‐2TC) analysis for X‐ray photon correlation spectroscopy that enables efficient analysis of ...

Reviewing fast or slow: A theory of summary reversal in the judicial hierarchy

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Appellate courts with discretionary dockets have multiple ways to review lower courts. We develop a formal model that evaluates the trade‐offs between “full review”—which features full briefing, oral arguments, and signed opinions—versus “quick review,” where a higher court can summarily reverse a lower court. We show that having the option of

Why did Putin invade Ukraine? A theory of degenerate autocracy

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Many dictatorships end up with a series of disastrous decisions such as Hitler's attack on the Soviet Union or Saddam Hussein's aggression against Kuwait. Even if a certain policy choice is not ultimately fatal for the regime, such as Mao's Big Leap Forward or the Pol Pot's collectivization drive, they typically involve both a miscalculation ...

“I can do math!”: A self‐regulated learning intervention to enhance math‐related motivational factors and performance in middle school

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Introduction Self‐regulated learning (SRL) interventions have been widely recognized for their potential to enhance students' academic achievement; however, their effects on math‐related motivational constructs remain less explored. This study investigated the impact of an SRL intervention on multiple math‐related motivational factors (math ...

An extension of the basic local independence model to multiple observed classifications

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model
