We Are Brothers in Conflict: Reading Prophet Obadiah Against the Context of Socio-Political and Ethno-Religious Hostility and Violence in Nigeria

open access: yesOld Testament Essays, 2017
This article discusses the semblances between the text of Prophet Obadiah and Nigeria within the socio-political, socio-economic, socio-ethnic, and the socio-religious contexts of conflict and hostility of the latter.

Plasmas in Gamma-Ray Bursts: Particle Acceleration, Magnetic Fields, Radiative Processes and Environments

open access: yesGalaxies, 2019
Being the most extreme explosions in the universe, gamma-ray bursts (GRBs) provide a unique laboratory to study various plasma physics phenomena. The complex light curve and broad-band, non-thermal spectra indicate a very complicated system on the one ...

On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

open access: yesAdvanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

AP Librae: The Extended Jet as the Source of VHE Emission?

open access: yesGalaxies, 2016
The LBL AP Librae has been detected in the TeV gamma-ray range, which is unexpected for this kind of blazar. The broad-band SED cannot be explained by a one-zone model, and especially fails in the TeV domain.

Jets and partons [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
Adapted from talks at XXVIII International Conference on High Energy Physics, Warsaw, July 1996 and at QCD Euroconference 96, Montpellier, July 1996. 13 pages with 11 figures. Figure 5 has some defective postscript code that may confuse ghostview, but it prints correctly.

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias

open access: yesAdvanced Engineering Materials, EarlyView.
Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

An extraordinary view of the universe: The use of X-ray vision in space science

open access: yesMètode Science Studies Journal: Annual Review, 2017
X-ray emission from cosmic sources indicates that these sources are heated to temperatures exceeding a million degrees or that they contain highly energetic particles.

Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection

Time-Mean Helicity Distribution in Turbulent Swirling Jets

open access: yesActa Polytechnica, 2005
Helicity offers an alternative approach to investigations of the structure of turbulent flows. Knowledge of the spatial distribution of the time-mean component of helicity is the starting point.

Chiral Phase Change Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...
