Tunneling in Persistent Luminescence

open access: yesAdvanced Optical Materials, EarlyView.
Key experimental criteria are provided for the occurrence of thermal/athermal tunneling and localized transitions. Many experimental studies of PersL have assigned tunneling on the basis of the linear relationship of PersL decay between intensity, I, and time, t−k, where k is a constant or I−1 versus t.

A methodology for collecting valid software engineering data [PDF]

open access: yes, 1982
An effective data collection method for evaluating software development methodologies and for studying the software development process is described. The method uses goal-directed data collection to evaluate methodologies with respect to the claims made ...

Application of the heuristic-systematic model to computer code trustworthiness: The influence of reputation and transparency

open access: yesCogent Psychology, 2017
Computer programs (code) are integral to the functions of current society. Yet, little is known about why programmers trust code they did not create. The current paper applied the heuristic-systematic model (HSM) of information processing to perceptions ...

BP/MoS₂ Van Der Waals Heterojunctions for Self‐Powered Photoconduction

open access: yesAdvanced Optical Materials, EarlyView.
A multilayer black phosphorus (BP)/monolayer MoS₂ vertical heterostructure is investigated using four‐probe measurements. The device exhibits rectifying behavior, dominant n‐type transport, low contact resistance, and an interface barrier of 68 meV.

Application Software, Domain-Specific Languages, and Language Design Assistants [PDF]

open access: yes, 2000
While application software does the real work, domain-specific languages (DSLs) are tools to help produce it efficiently, and language design assistants in turn are meta-tools to help produce DSLs quickly. DSLs are already in wide use (HTML for web pages,

940 nm Micro‐Light‐Emitting Diode Fabricated on Industry‐Compatible 300 mm Si (100) Substrate by Metal–Organic Chemical Vapor Deposition

open access: yesAdvanced Photonics Research, EarlyView.
The fabrication of 940 micro‐light‐emitting diodes on both 300 mm Si and Ge/Si wafers has been demonstrated using direct metal–organic chemical vapor deposition epitaxy. These promising results show the potential for monolithic integration of III‐As onto complementary metal‐oxide‐semiconductor (CMOS)‐compatible silicon platforms. This achievement opens

The development and technology transfer of software engineering technology at NASA. Johnson Space Center [PDF]

open access: yes
The United State's big space projects of the next decades, such as Space Station and the Human Exploration Initiative, will need the development of many millions of lines of mission critical software. NASA-Johnson (JSC) is identifying and developing some

Supporting collaborative grid application development within the escience community [PDF]

open access: yes, 2003
The systemic representation and organisation of software artefacts, e.g. specifications, designs, interfaces, and implementations, resulting from the development of large distributed systems from software components have been addressed by our research ...

Thermal Shrinkage‐Induced Modifications in Photonic Bandgaps of Two‐Photon Polymerized Bragg Reflectors

open access: yesAdvanced Photonics Research, EarlyView.
Scanning electron microscopy and white‐light reflectance images of the pillar‐supported distributed Bragg reflector (DBR) are presented before and after thermal shrinkage. The DBR, fabricated via two‐photon polymerization, consists of alternating high‐ and low‐index layers supported by vertical pillars.
