Coarse-Grained Effective Hamiltonian via the Magnus Expansion for a Three-Level System

open access: yesEntropy, 2023
Quantum state processing is one of the main tools of quantum technologies. While real systems are complicated and/or may be driven by non-ideal control, they may nevertheless exhibit simple dynamics approximately confined to a low-energy Hilbert subspace.

Modified Supporting Materials to Fabricate Form Stable Phase Change Material with High Thermal Energy Storage

open access: yesMolecules, 2023
Thermal energy storage (TES) is vital to the absorption and release of plenty of external heat for various applications. For such storage, phase change material (PCM) has been considered as a sustainable energy material that can be integrated into a ...

Monitoring Scheme for the Detection of Hydrogen Leakage from a Deep Underground Storage. Part 2: Physico-Chemical Impacts of Hydrogen Injection into a Shallow Chalky Aquifer

open access: yesApplied Sciences, 2021
This paper presents the results of an experiment to simulate a sudden and brief hydrogen leak from a potential deep geological storage site. A 5 m3 volume of groundwater was extracted, saturated with hydrogen, and then reinjected into the aquifer ...

Automated Assessment of Peristomal Skin Discoloration and Leakage Area Using Artificial Intelligence

open access: yesFrontiers in Artificial Intelligence, 2020
For people living with an ostomy, development of peristomal skin complications (PSCs) is the most common post-operative challenge. A visual sign of PSCs is discoloration (redness) of the peristomal skin often resulting from leakage of ostomy output under

Asymmetric gate induced drain leakage and body leakage in vertical MOSFETs with reduced parasitic capacitance

open access: yes, 2006
Vertical MOSFETs, unlike conventional planar MOSFETs, do not have identical structures at the source and drain, but have very different gate overlaps and geometric configurations.

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).

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.
