We present a case of bile duct adenoma that mimicked hepatic metastasis from gastric cancer. The adenoma exhibited prolonged enhancement on dynamic computed tomography, hyperintensity on diffusion-weighted imaging, and diminished uptake of superparamagnetic iron oxide and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid on magnetic resonance imaging, resembling those of adenocarcinom...

A simple molecule, L, diethylenetriamine bearing anthracene fragments at both ends, behaves as a fluorescent molecular logic gate with "multiply-configurable dual outputs", capable of demonstrating five different logic functions operated by proton (H+) and transition metal cations (Mn+) as inputs.

Visible pump-probe spectroscopy has been used to identify and characterize short-lived metal-to-metal charge transfer (MMCT) excited states in a group of cyano-bridged mixed-valence complexes of the formula [LCo(III)NCM(II)(CN)(5)](-), where L is a pentadentate macrocyclic pentaamine (L(14)) or triamine-dithiaether (L(14S)) and M is Fe or Ru. Nanosecond pump-probe spectroscopy on frozen solutio...

We consider the spatially flat Friedmann model ds = dt − a(t)(dx + dy + dz) . For a ≈ tp, especially, if p ≥ 1, this is called power-law inflation. For the Lagrangian L = Rm with p = −(m − 1)(2m − 1)/(m − 2) power-law inflation is an exact solution, as it is for Einstein gravity with a minimally coupled scalar field Φ in an exponential potential V (Φ) = exp(μΦ) and also for the higher-dimension...

Rn×Rn S( x+ y 2 , η) e2iπ〈x−y, η〉 u(y) dy dη : such a linear operator extends as a continuous operator from S ′(Rn) to S(R) while, in the case when S ∈ S ′(Rn ×R) , one can still define Op(S) as a linear operator from S(R) to S ′(Rn) ; also, Op sets up an isometry from L(R×R) onto the space of Hilbert-Schmidt operators on L(R) . The sharp composition S1#S2 of two symbols, say lying in S(R×R) , ...

A flocculant (DES0-0) was synthesized by epichlorohydrin and diethylamine, followed adding crosslinking agent such as ethylenediamine, diethylenetriamine triethylenetriamine to obtain the crosslinked polymer DES0-1, DES0-2, DES0-3. The flocculation effect of DES0-3 PAM studied measuring volume, transmittance particle size clarified solution after flocculation. results showed that triethylenetet...

A facile in situ partial surface-oxidation strategy to integrate CoO domains with CoSe2 nanobelts on Ti mesh (denoted as CoO/CoSe2) via direct calcination of CoSe2-diethylenetriamine precursors is reported. The resulted self-supported CoO/CoSe2 exhibits an outstanding activity and stability in neutral media toward both hydrogen evolution reaction and oxygen evolution reaction.
