GOVERNING THE CLOUD: Infrastructural Statecraft and the Political Ecology of Digital Expansion in Oregon

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Oregon's wave of data center and semiconductor projects shows how cloud capitalism reorganizes resource systems and territorial governance. Examining Amazon, Google, and Intel, the article traces how fiscal incentives, utility programs, and land‐use instruments are recalibrated to secure hyperscale loads.

Allele‐informed QTL‐seq identifies Hd18 as a minor modifier of heading date in elite rice cultivars

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Fine‐tuning heading date is critical for optimizing yield, grain quality, and local adaptation in rice (Oryza sativa L.). QTL‐seq (where QTL is quantitative trait locus), which integrates bulked segregant analysis with whole‐genome resequencing, provides a rapid and cost‐effective approach for identifying QTLs underlying complex traits ...

Modelling Interdependent Cascading Failures in Real World Complex Networks using a Functional Dependency Model [PDF]

open access: yes, 2015
Infrastructure systems are becoming increasingly complex and interdependent. As a result our ability to predict the likelihood of large-scale failure of these systems has significantly diminished and the consequence of this is that we now have a ...

IOT-Powered Substation Surveillance System

open access: yesInternational Journal of Current Science Research and Review
An IoT-based substation monitoring system provides an intelligent and efficient means for the continuous, real-time observation of critical parameters in power substations, overcoming the shortcomings of conventional monitoring that predominantly depends on manual inspection. This system incorporates IoT sensors to continually monitor voltage, current,

Assessing the Dynamic Resilience of Urban Road System: A Case Study of Xiamen City, China

open access: yesJournal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Urban road system resilience is critical for managing extreme flood events, yet existing assessments predominantly focus on static indicators that capture inherent system capacity rather than dynamic responses to disturbances. This study proposes a dynamic resilience analysis framework that tracks urban road system performance under ...
