Measurement of methane emissions from abandoned oil and gas wells in Hillman State Park, Pennsylvania

open access: yesCarbon Management, 2018
Abandoned oil and gas wells, improperly plugged or unplugged, present a risk to current and future oil and gas development because they provide a potential pathway for unwanted gas and fluid migration to the surface.

Leakage-Resilient Storage [PDF]

open access: yes, 2010
We study a problem of secure data storage on hardware that may leak information. We introduce a new primitive, that we call leakage-resilient storage (LRS), which is an (unkeyed) scheme for encoding messages, and can be viewed as a generalization of the All-Or-Nothing Transform (AONT, Rivest 1997).

Increase in blood–brain barrier leakage in healthy, older adults

open access: yesGeroScience, 2020
Blood–brain barrier (BBB) breakdown can disrupt nutrient supply and waste removal, which affects neuronal functioning. Currently, dynamic contrast-enhanced (DCE) MRI is the preferred in-vivo method to quantify BBB leakage.

Influence of the gate leakage current on the stability of organic single-crystal field-effect transistors

open access: yes, 2004
We investigate the effect of a small leakage current through the gate insulator on the stability of organic single-crystal field-effect transistors (FETs).

Study into Structural Impact of Novel Calcium Complex Grease Delivering High Temperature Performance

open access: yesTribology Online, 2016
We newly developed the prototype calcium complex grease (Cx-S) which delivered a better temperature performance than traditional calcium complex greases and could keep its structure even over 200°C.

A New Mass Spectroscopy-Based Method for Assessing the Periodontal–Endodontic Interface after Intracanal Placement of Biomaterials In Vitro

open access: yesJournal of Functional Biomaterials, 2023
Optimizing the interface between biomaterials and dental hard tissues can prevent leakage of bacteria or inflammatory mediators into periapical tissues and thus avoid alveolar bone inflammation.

Data leakage inflates prediction performance in connectome-based machine learning models

open access: yesNature Communications
Predictive modeling is a central technique in neuroimaging to identify brain-behavior relationships and test their generalizability to unseen data. However, data leakage undermines the validity of predictive models by breaching the separation between ...

Remote sensing of methane leakage from natural gas and petroleum systems revisited

open access: yesAtmospheric Chemistry and Physics, 2020
. The switch from the use of coal to natural gas or oil for energy generation potentially reduces greenhouse gas emissions and thus the impact on global warming and climate change because of the higher energy creation per CO2 molecule emitted.

An Operational Approach to Information Leakage [PDF]

open access: yesIEEE Transactions on Information Theory, 2018
Given two random variables $X$ and $Y$ , an operational approach is undertaken to quantify the “leakage” of information from $X$ to $Y$ . The resulting measure $\mathcal {L}\left ({X \!\! \to \!\!

Constructing Functional Braids for Low-Leakage Topological Quantum Computing [PDF]

open access: yes, 2008
We discuss how to significantly reduce leakage errors in topological quantum computation by introducing an irrelevant error in phase, using the construction of a CNOT gate in the Fibonacci anyon model as a concrete example. To be specific, we construct a
