Parallel ELLPACK for Shared Memory Multiprocessors [PDF]

, 1992
This paper describes a parallel version of ELLPACK for shared memory multiprocessors. ELLPACK is a system for numerically solving elliptic PDEs. It consists of a very high level language for defining PDE problems and selecting methods of solution, and a ...

Structure and Mechanism of PhdC, a Prenylated‐Flavin Maturase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Prenylated flavin mononucleotide (prFMN) is a modified flavin cofactor required by the UbiD family of (de)carboxylase enzymes. While the reduced prFMNH2 form is produced by the flavin prenyltransferase UbiX, the corresponding two‐electron oxidized prFMNiminium form is required to support UbiD catalysis. Thus, oxidative maturation of prFMNH2 is

Aspirations and Apprehensions: Reconciling Youths' Desires and Concerns for a Sustainable Future

Sustainable Development, EarlyView.
ABSTRACT Although youth are widely acknowledged as change agents, their full participation is often limited by immediate concerns. This study examines how young people's aspirations shape their engagement with sustainability amid economic, environmental, and social uncertainties. Drawing on a large‐scale international survey (n: 15,076) and multinomial

Quantifying UAS Observation Error Variance Used in Data Assimilation Systems and Its Impact on Predictive Skill

Journal of Advances in Modeling Earth Systems
Observation error determines the weights of the observations and background state used in data assimilation to generate analyses. Quantifying observation error is critical for the optimal assimilation of observational data sets. Uncrewed Aircraft System (

Navigating uncertainty in a nascent ecosystem: How shifting cognitive frames influence an incumbent firm's platform scope strategies

Strategic Management Journal, EarlyView.
Abstract Research Summary We examine how an incumbent firm navigates internal and external uncertainties when entering a nascent platform ecosystem. Drawing on a longitudinal study of a large telecommunication firm's transition into an evolving IoT ecosystem, we advance a cognitive perspective on platform strategy.

The Role of Māori Values in Corporate Culture and CSR: A Comparative Study in Aotearoa‐New Zealand's Fishing Industry

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This study explores the interaction of organisational culture, corporate social responsibility (CSR) and Indigenous values in Aotearoa‐New Zealand's fishing industry, focusing on Māori‐owned and non–Māori‐owned companies. It reveals how Māori values shape company culture and how CSR aligns with them. Using Hofstede's cultural dimensions theory,

A modified least-squares collocation method for the determination of crustal deformation: first results in the Swiss Alps [PDF]

, 2017
The calculation of recent crustal movements and the associated crustal deformation rely on a suitable interpolation of geodetic measurements with repetition cycles of years or decades and modern GPS permanent networks.

The Anionically All‐Boron‐Based Anti‐Perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12]

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anionically all‐boron‐based colorless anti‐perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12] can be obtained by isothermal evaporation from aqueous solutions of the underlying pseudo‐binary components Cs2[B12H12] and Cs[BH4] or Cs[BF4]. At ambient conditions, Cs3[BH4][B12H12] crystallizes trigonally (R3¯$\overline{3}$m) and transforms reversibly ...
