Klein paradox for bosons, wave packets and negative tunnelling times
(Nature, 2020-11-05)
We analyse a little known aspect of the Klein paradox. A Klein-Gordon boson appears to be able to cross a supercritical rectangular barrier without being reflected, while spending there a negative amount of time. The ...
Nanofocusing of acoustic graphene plasmon polaritons for enhancing mid-infrared molecular fingerprints
(De Gruyter, 2020)
Mid-infrared (mid-IR) optical spectroscopy of molecules is of large interest in physics, chemistry, and biology. However, probing nanometric volumes of molecules is challenging because of the strong mismatch of their ...
Toward Supramolecular Nanozymes for the Photocatalytic Activation of Pt(IV) Anticancer Prodrugs
(Royal Society Of Chemistry, 2020-09-16)
A supramolecular nanozyme for the photocatalytic conversion of a Pt(IV) anticancer complex to cisplatin is described herein. We employed 1.9 nm Au nanoparticles decorated with thiol ligands bearing a TACN (1,4,7-triazacyclononane) ...
The effects of contextual diversity on incidental vocabulary learning in the native and a foreign language
(Scientific Reports, 2020)
Vocabulary learning occurs throughout the lifespan, often implicitly. For foreign language learners, this is particularly challenging as they must acquire a large number of new words with little exposure. In the present ...
Dermic-derived fibroblasts for the study of amyotrophic lateral sclerosis

First search for the ηc2(1D) in B decays at Belle
(Springer, 2020-05-08)
The first dedicated search for the ηc2(1D) is carried out using the decays B+→ ηc2(1D)K+, B0 → ηc2(1D)K0S, B0→ ηc2(1D)π−K+, and B+→ ηc2(1D)π+K0S with ηc2(1D) → hcγ. No significant signal is found. For the ηc2(1D) mass range ...
The effect of orthography on the recognition of pronunciation variants
(Journal of Experimental Psychology: Learning, Memory, and Cognition, 2020)
In conversational speech, it is very common for words’ segments to be reduced or deleted. However,
previous research has consistently shown that during spoken word recognition, listeners prefer words’
canonical pronunciation ...

(2020-05-27)
Justificación: Entre las complicaciones más frecuentes de la diabétes mellitus (DM) destacan las úlceras de pie diabético (UPD) , que son un importante problema de salud tanto para las personas que las padecen como para ...
A Dual-Species Bose-Einstein Condensate with Attractive Interspecies Interactions
(MDPI, 2020-03-21)
We report on the production of a 41 K- 87 Rb dual-species Bose–Einstein condensate with tunable interspecies interaction and we study the mixture in the attractive regime; i.e., for negative values of the interspecies ...
Some New Results on Coincidence Points for Multivalued Suzuki-Type Mappings in Fairly Complete Spaces
(MDPI, 2020-03-17)
In this paper, we introduce Suzuki-type generalized and modified proximal contractive mappings. We establish some coincidence and best proximity point results in fairly complete spaces. Also, we provide coincidence and ...
