Observation of a possible superflare on Proxima Centauri [PDF]

, 2019
We report the observation on UT 2017 July 1 of an unusually powerful flare detected in near-infrared continuum photometry of Proxima Centauri. During a campaign monitoring the star for possible exoplanet transits, we identified an increase in Sloan i ...

Induced Representations of the Two Parametric Quantum Deformation U$_{pq}$[gl(2/2)]

, 2000
The two-parametric quantum superalgebra $U_{p,q}[gl(2/2)]$ and its induced representations are considered. A method for constructing all finite-dimensional irreducible representations of this quantum superalgebra is also described in detail. It turns out

Value Creation by Support Organizations Through the Prism of Conflicting Institutional Logics

International Journal of Management and Economics, 2018
The article sets out to explore how conflicting institutional logics of support organizations influence their value creation. Value creation undertaken by support organizations does not directly reflect their missions. Even though one can generalize that

E. coli Toxin YjjJ (HipH) Is a Ser/Thr Protein Kinase That Impacts Cell Division, Carbon Metabolism, and Ribosome Assembly

mSystems, 2023
Protein Ser/Thr kinases are posttranslational regulators of key molecular processes in bacteria, such as cell division and antibiotic tolerance. Here, we characterize the E.

Finite-Dimensional Representations of the Quantum Superalgebra U$_{q}$[gl(2/2)]: II. Nontypical representations at generic $q$

, 1994
The construction approach proposed in the previous paper Ref. 1 allows us there and in the present paper to construct at generic deformation parameter $q$ all finite--dimensional representations of the quantum Lie superalgebra $U_{q}[gl(2/2)]$.

Adiabatic Heating of Contracting Turbulent Fluids [PDF]

, 2012
Turbulence influences the behavior of many astrophysical systems, frequently by providing non-thermal pressure support through random bulk motions.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Scaling Up Organic Agricultural Enterprises: An Empirical Study of the Role of Associations of Micro Producers

Business Systems Research
Development of organic agricultural entrepreneurship often requires “scaling up” from a multitude of individual, largely disconnected micro organic enterprises with haphazard achievements, toward more integrated units, operating more systematically and ...
