Measuring space charge and electric field in axisymmetric dielectric barrier discharge using EFISH technique

open access: yesScientific Reports
We investigated the dynamic interactions between electric fields and space charges within an axisymmetric dielectric barrier discharge (DBD) configuration.

Phase space renormalization and finite BMS charges in six dimensions

open access: yesJournal of High Energy Physics, 2023
We perform a complete and systematic analysis of the solution space of six-dimensional Einstein gravity. We show that a particular subclass of solutions — those that are analytic near I $$ \mathcal{I} $$ + — admit a non-trivial action of the generalised ...

Renewed Concepts for Electric Charge, Electric Current and Magnetic Charge by the Energy Circulation Theory

open access: yesReports in Advances of Physical Sciences, 2023
The existing electromagnetism (EM) expects isolated elementary electric charges [Formula: see text] or [Formula: see text], and allows their clusters [Formula: see text].

Surface charge algebra in gauge theories and thermodynamic integrability

open access: yes, 2007
Surface charges and their algebra in interacting Lagrangian gauge field theories are investigated by using techniques from the variational calculus. In the case of exact solutions and symmetries, the surface charges are interpreted as a Pfaff system ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Dual gravitational charges and soft theorems

open access: yesJournal of High Energy Physics, 2019
We consider the consequences of the dual gravitational charges for the phase space of radiating modes, and find that they imply a new soft NUT theorem. In particular, we argue that the existence of these new charges removes the need for imposing boundary

Nonlocal charges of T-dual strings

open access: yes, 2006
We obtain sets of infinite number of conserved nonlocal charges of strings in a flat space and pp-wave backgrounds, and compare them before and after T-duality transformation.

Monopole-Antimonopole Pair Dyons [PDF]

open access: yes, 2010
Monopole-antimonopole pair (MAP) with both electric and magnetic charges are presented. The MAP possess opposite magnetic charges but they carry the same electric charges.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Wiggling Throat of Extremal Black Holes [PDF]

open access: yes, 2015
We construct the classical phase space of geometries in the near-horizon region of vacuum extremal black holes as announced in [arXiv:1503.07861]. Motivated by the uniqueness theorems for such solutions and for perturbations around them, we build a ...
