Novel C20 Conjugated Fatty Acids as Biohydrogenation Intermediates in Paraclostridium bifermentans

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this paper, we report a detailed characterization of the eicosapentaenoic acid (EPA) hydrogenation pathway in Paraclostridium bifermentans JCM 1386T, including the identification of novel intermediates of conjugated EPAs, cis‐5,cis‐8,cis‐11,trans‐13,cis‐17‐20:5 (CEPA1) and cis‐5,cis‐8,trans‐11,trans‐13,cis‐17‐20:5 (CEPA2) by nuclear ...

On the Proper Treatment of Dynamics in Cognitive Science

Topics in Cognitive Science, EarlyView., 2023
Abstract This essay examines the relevance of dynamical ideas for cognitive science. On its own, the mere mathematical idea of a dynamical system is too weak to serve as a scientific theory of anything, and dynamical approaches within cognitive science are too rich and varied to be subsumed under a single “dynamical hypothesis.” Instead, after first ...

Kepler-16b: safe in a resonance cell

, 2013
The planet Kepler-16b is known to follow a circumbinary orbit around a system of two main-sequence stars. We construct stability diagrams in the "pericentric distance - eccentricity" plane, which show that Kepler-16b is in a hazardous vicinity to the ...

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...

Kepler Bonus: Light Curves of Kepler Background Sources

The Astronomical Journal, 2023
NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...

The third transit of snow-line exoplanet Kepler-421b [PDF]

, 2016
The Kepler Mission has uncovered a handful of long-period transiting exoplanets that orbit from the cold outer reaches of their systems, despite their low transit probabilities.

The California-Kepler Survey. VIII. Eccentricities of Kepler Planets and Tentative Evidence of a High-metallicity Preference for Small Eccentric Planets [PDF]

Astronomical Journal, 2019
Characterizing the dependence of the orbital architectures and formation environments on the eccentricity distribution of planets is vital for understanding planet formation.

Radial Velocity Monitoring and Analysis of Gaia Astrometry of Selected Intermediate Mass Stars to Constrain Their Multiplicity Status

Astronomische Nachrichten, EarlyView.
ABSTRACT We present new radial velocity measurements of 13 selected intermediate mass stars (2–6 M⊙). The measurements were performed between 29 April and 6 September 2024 at the University Observatory Jena using the échelle spectrograph FLECHAS. The radial velocity of eight stars was found to be constant during our spectroscopic monitoring, namely: 17

ALGEBRAIC DESCRIPTION OF SHAPE INVARIANCE REVISITED

Acta Polytechnica, 2017
We revisit the algebraic description of shape invariance method in one-dimensional quantum mechanics. In this note we focus on four particular examples: the Kepler problem in flat space, the Kepler problem in spherical space, the Kepler problem in ...

Demystifying Kepler Data: A Primer for Systematic Artifact Mitigation

, 2012
The Kepler spacecraft has collected data of high photometric precision and cadence almost continuously since operations began on 2009 May 2. Primarily designed to detect planetary transits and asteroseismological signals from solar-like stars, Kepler has
