Elucidating the Supramolecular Interaction of Positively Supercharged Fluorescent Protein with Anionic Phthalocyanines

open access: yesAdvanced Biology, EarlyView.
Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

The Clientele Effect in the Brazilian Market: Are Investors Irrational?

open access: yesRevista Brasileira de Finanças, 2003
This work tests the dividend clientele effect in the Brazilian stock market between 1989 and 1993, a period during which there no dividends taxes varied between zero and 25% according to shareholders group. From a sample of 693 events studied, 47% showed

Equitable Defenses in Patent Law [PDF]

open access: yes, 2020
In patent law, “unenforceability” can have immense consequences. At least five equitable doctrines make up the defense of “unenforceability” as it was codified into the Patent Act in 1952: laches; estoppel; unclean hands; patent misuse; and according to ...

Contrasting the beam interaction characteristics of selected lasers with a partially stabilised zirconia (PSZ) bio-ceramic [PDF]

open access: yes, 2002
Differences in the beam interaction characteristics of a CO2 laser, a Nd:YAG laser, a high power diode laser (HPDL) and an excimer laser with a partially stabilised zirconia (PSZ) bio-ceramic have been studied.

Spatiotemporal Control Over Protein Release from Artificial Cells via a Light‐Activatable Protease

open access: yesAdvanced Biology, EarlyView.
Stimulus‐responsive protein release is essential for intercellular communication. Mimicking this functionality in artificial cells is promising to study the working principles of cellular signaling. Herein, an engineered light‐activatable protease is implemented in a coacervate‐based artificial cell platform to establish user‐defined spatiotemporal ...

A política de dividendos como geradora de economia fiscal e do desenvolvimento do mercado de capitais: uma proposta criativa

open access: yesRAE: Revista de Administração de Empresas, 1993
A fome fiscal do governo brasileiro tem sido reclamada constantemente pelo empresariado local. Apesar disso, e sabendo que a taxação dos dividendos não existe, ao mesmo tempo em que a sobre ganhos de capital foi instituída, podemos verificar que através ...

Characterization and Optimization of Vesicle Properties in bioPISA: from Size Distribution to Post‐Assembly Loading

open access: yesAdvanced Biology, EarlyView.
The paper explores the creation and characterization of vesicles through biocatalytic Polymerization‐Induced Self‐Assembly (bioPISA), focusing on achieving size uniformity using centrifugation techniques. It examines the effects of stirring speed on vesicle morphology and analyses the internal polymer‐rich structure using fluorescence correlation ...

What is an atom laser? [PDF]

open access: yesarXiv, 1996
An atom laser is a hypothetical device which would produce an atomic field analogous to the electromagnetic field of a photon laser. Here I argue that for this analogy to be meaningful it is necessary to have a precise definition of a laser which applies equally to photon or atom lasers.

Optimization of laser pumping for the generation of multi-pulse structures in fiber lasers [PDF]

open access: yesJOSA B, 2024
We address the challenge of configuring a fiber laser cavity to enable efficient access to multi-pulse structures such as dissipative soliton molecules. We theoretically compare multi-pulsing routes in the parameter space of the laser. By using a two-dimensional parameter space, we experimentally demonstrate an important reduction in the laser pumping ...
