Intermediate Resolution Near-Infrared Spectroscopy of 36 late-M Dwarfs [PDF]

open access: yesThe Astronomical Journal, 2012
We present observations of 36 late-M dwarfs obtained with the KeckII/NIRSPEC in the J-band at a resolution of \sim20,000. We have measured projected rotational velocities, absolute radial velocities, and pseudo-equivalent widths of atomic lines.

New synthesis of a late-stage tetracyclic key intermediate of lumateperone

open access: yesBeilstein Journal of Organic Chemistry, 2022
New approaches have been tested for the synthesis of lumateperone intermediates. As a result of these efforts, a novel synthesis of the late-stage tetracyclic key intermediate of lumateperone starting from the commercially available quinoxaline is ...

Resolving Late-Stage Intermediates of Eukaryotic Ribosome Assembly [PDF]

open access: yesStructure, 2017
The assembly of eukaryotic ribosomes requires about 200 assembly factors promoting RNA modification, folding, cleavage, and ribosomal protein association. In this issue of Structure, Johnson et al. (2017) report structures of several late-stage intermediates of pre-40S ribosomal subunit assembly.

Photocatalytic Late-Stage Functionalization of Sulfonamides via Sulfonyl Radical Intermediates

open access: yesACS Catalysis, 2022
A plethora of drug molecules and agrochemicals contain the sulfonamide functional group. However, sulfonamides are seldom viewed as synthetically useful functional groups. To confront this limitation, a late-stage functionalization strategy is described, which allows sulfonamides to be converted to pivotal sulfonyl radical intermediates.

The star formation history of intermediate-redshift late-type galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
We combine the latest observations of disk galaxy photometry and rotation curves at moderate redshift from the FORS Deep Field (FDF) with simple models of chemical enrichment. Our method describes the buildup of the stellar component through infall of gas and allows for gas and metal outflows.

Late-onset Huntington disease with intermediate CAG repeats: true or false? [PDF]

open access: yesJournal of Neurology, Neurosurgery & Psychiatry, 2010
Huntington disease (HD) is a neurodegenerative disorder associated with an expanded CAG trinucleotide repeat length in the huntingtin gene. 'Intermediate alleles' with 27 to 35 CAG repeats generally do not cause HD but are unstable upon germ-line transmission.

Multiperspective smFRET reveals rate-determining late intermediates of ribosomal translocation [PDF]

open access: yesNature Structural & Molecular Biology, 2016
Directional translocation of the ribosome through the mRNA open reading frame is a critical determinant of translational fidelity. This process entails a complex interplay of large-scale conformational changes within the actively translating particle, which together coordinate the movement of tRNA and mRNA substrates with respect to the large and small

Late-time evolution of charged massive Dirac fields in the Kerr-Newman background [PDF]

open access: yes, 2006
We investigate both the intermediate late-time tail and the asymptotic tail behavior of the charged massive Dirac fields in the background of the Kerr-Newman black hole.

Sobre alfarería, cementerios, fases y procesos durante la prehistoria tardía del desierto de Atacama (800-1600 DC)

open access: yesEstudios Atacameños, 2002
En este artículo se somete a revisión la problemática cultural y temporal de la prehistoria tardía del desierto de Atacama de acuerdo a un estudio sistemático y comparativo de la alfarería funeraria de las dos cuencas, San Pedro y el Loa, que componen ...
