Bond Laddering and Bond Indexing: An Empirical Comparison

open access: yesSSRN Electronic Journal, 2016
Bond laddering and bond indexing have been widely accepted approaches to bond investing among retail investors. However, bond laddering has virtually been ignored in both the academic literature and most of the popular investment textbooks. One thing both approaches have in common is that they are passive strategies with no attempt whatsoever to beat ...

The bonding situation in triethylchalcogenostiboranes – polarized single bonds vs. double bonds

open access: yesDalton Trans., 2014
Triethylchalcogenostiboranes Et3Sb[double bond, length as m-dash]E (E = S , Se ) were synthesized and their solid state structures were determined. The Sb-Se bond length is the shortest ever reported. Short SbE contacts were not observed. According to quantum chemical calculations, the bonding situation in and is best described as a polarized Sb-E ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Estudo comparativo entre a agressividade superficial obtida na retificação com rebolos de óxido de alumínio e CBN, fabricados com ligantes resinóide e vitrificado The evaluation of the bond resin and vitrified and abrasive grain CBN and alumina influence in the grinding wheel topography characteristics, by the study of the grinding wheel sharpness

open access: yesCerâmica, 2011
Este artigo apresenta um estudo da agressividade do rebolo (habilidade de corte). A retificação é um processo de usinagem preciso, o qual é amplamente usado na manufatura de componentes que requerem tolerâncias estreitas e superfícies bem acabadas.

Bond Length and Bond Order in One of the Shortest Cr−Cr Bonds

open access: yesInorganic Chemistry, 2008
Multiconfigurational quantum chemical calculations on the R-diimines dichromium compound confirm that the Cr-Cr bond, 1.80 A, is among the shortest Cr(I)-Cr(I) bonds. However, the bond between the two Cr atoms is only a quadruple bond rather than a quintuple bond. The reason why the bond is so short has to be attributed to the strain in the NCCN ligand

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Orthodontic Metallic Lingual Brackets: The Dark Side of the Moon of Bond Failures?

open access: yesJournal of Functional Biomaterials, 2017
Lingual orthodontics, among both young and adult patients, increased in popularity during last years. The purposes of the present investigation were to evaluate the shear bond strength (SBS) values and Adhesive Remnant Index (ARI) scores of different ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
