Ultra-High-Performance Liquid Chromatography–Electrospray Ionization–High-Resolution Mass Spectrometry for Distinguishing the Origin of Ellagic Acid Extracts: Pomegranate Peels or Gallnuts

open access: yesMolecules
Ellagic acid, known for its various biological activities, is widely used. Ellagic acid from pomegranate peels is safe for consumption, while that from gallnuts is only suitable for external use. However, there is currently no effective method to confirm

The Mass-Spectrum of Copper [PDF]

open access: yesNature, 1923
THE number of elements of which the isotopic nature has been determined is now large enough to give considerable weight to statistical relations. Among elements of odd atomic number two definite empirical rules stand out. The first is that none of them consists of more than two isotopes. This has no exception so far.

Cytosolic‐enhanced dark Epac‐based FRET sensors allow for intracellular cAMP detection in live cells via FLIM

open access: yesFEBS Letters, EarlyView.
We describe a novel set of Epac‐based FRET‐FLIM biosensors with improved fully cytosolic distribution, achieved without compromising the state‐of‐the‐art performance of our original designs, for detecting cAMP dynamics in real time in live cells with high precision and reliability.

Suppression of Interference of Fixative With Odorant Samples in Mass Spectrum Using ICA

open access: yesIEEE Access, 2021
Odor sensing enables us to sense odorant stimuli. This sensation causes a deep subconscious response in humans in various ways and represents an indispensable sensation in daily life.

Glueball mass spectrum from supergravity [PDF]

open access: yes, 1998
We calculate the spectrum of glueball masses in non-supersymmetric Yang-Mills theory in three and four dimensions, based on a conjectured duality between supergravity and large N gauge theories.

The [2Fe‐2S] cluster of mitochondrial outer membrane protein mitoNEET has an O2‐regulated nitric oxide access tunnel

open access: yesFEBS Letters, EarlyView.
The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.

Top-quark mass from the diphoton mass spectrum

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We calculate the $$gg\rightarrow \gamma \gamma $$ g g → γ γ amplitude by including the $$t\bar{t}$$ t t ¯ bound-state effects near their mass threshold.

Sensory Evaluation of Interference Suppression in Odor Reproduction Using Mass Spectrometry

open access: yesIEEE Access, 2023
Odor sensing enables us to sense odorant stimuli. This sensation causes a deep subconscious response in humans in various ways and represents an indispensable sensation in daily life.

A New Method for Drawing the Capacity Spectrum for Seismic Analysis and Structural Rehabilitation [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2020
A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures.

ppbar enhancement in B and J/Psi decay

open access: yes, 2006
The near-threshold enhancement in the ppbar invariant mass spectrum from the B^+ -> K^+ ppbar decay reported recently by the BaBar Collaboration is studied within the J\"ulich NNbar model.
