LDPC Codes on Balanced Incomplete Block Designs: Construction, Girth, and Cycle Structure Analysis

Entropy
In this paper, we investigate the cycle structure inherent in the Tanner graphs of low-density parity-check (LDPC) codes constructed from balanced incomplete block designs (BIBDs).

“Why?”: C. Wright Mills on the Spirit of the Classical Sociological Tradition and Positivist Versus Critical Sociology

Sociology Lens, EarlyView.
ABSTRACT Despite their very diverse interests, the classical sociological thinkers were concerned with analyzing the dramatic social transformations in the wake of colonialism, slavery, and modern industrial capitalism as well as the multiple revolutions, particularly in relation to the new forms of social inequalities and power disparities.

The Armendariz Graph of a Ring

Discussiones Mathematicae - General Algebra and Applications, 2018
In this paper we initiate the study of Armendariz graph of a commutative ring R and investigate the basic properties of this graph such as diameter, girth, domination number, etc.

A Multimodal Machine Learning Model for Framingham Risk Score–Based Cardiovascular Risk Stratification in Patients With Obstructive Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT Machine learning provides a powerful tool to capture complex, nonlinear patterns in biomedical data and enhance precision risk stratification. In this study, we applied a multilayer perceptron (MLP) framework to classify Framingham Risk Score–based cardiovascular risk categories in patients with obstructive sleep apnea (OSA).

Proprioception drives tension wood formation for autotropic straightening and postural control in trees

New Phytologist, EarlyView.
Proprioception controls trunk straightness in trees through opposite tension wood formation. A spherical growth chamber (a), combined with a two‐dimensional rotating clinostat (b2), suppresses gravi‐ and phototropic sensing. The tree is first tilted horizontally (b1), triggering upward gravitropic bending, actuated by tension wood formation on the ...

Who Is Accountable? How Citizens Attribute Success and Failure in Cross‐Sector Collaborations

Public Administration, EarlyView.
ABSTRACT Cross‐sector collaborations bring together organizations with different values, missions, and goals to achieve shared outcomes. However, how accountability is attributed across sectors remains unclear, particularly given the potential influence of sector bias on citizen perceptions.

Maximizing Spectral Radii of Uniform Hypergraphs with Few Edges

Discussiones Mathematicae Graph Theory, 2016
In this paper we investigate the hypergraphs whose spectral radii attain the maximum among all uniform hypergraphs with given number of edges. In particular we characterize the hypergraph(s) with maximum spectral radius over all unicyclic hypergraphs ...

Policymakers' Preferences Over Public–Private Modes of Service Delivery and Credit‐Claiming: Experimental Evidence

Public Administration, EarlyView.
ABSTRACT A survey experiment on US elected local policymakers allows us to test how incumbents strategically use infrastructure projects in their electoral campaigns. Each local official is presented with a scenario in which they are asked to imagine that they are going to run for office again and that a new infrastructure project has just been ...

Public Service Delegation and the Mechanisms of Blame Attribution: Evidence From a Survey Experiment on Public Service Failure

Public Administration Review, EarlyView.
ABSTRACT A growing body of experimental public administration research examines how structural arrangements in public services, such as delegating service delivery to public or private actors, shape citizens' blame attributions for service failures. However, the mechanisms underlying these attributions are less well understood.

TOTAL NEAR-RING GRAPH [PDF]

Journal of Algebraic Systems
Let N be a right near-ring. Let Z(N) be the set of right zero-divisors of N.We dene total near-ring graph of N as a graph whose vertex set is the set of allelements of the near-ring N and any two distinct vertices n1; n2 2 N are adjacentif and only if n1
