The factorization method for the Askey–Wilson polynomials

open access: yesJournal of Computational and Applied Mathematics, 1999
A special Infeld-Hall factorization is given for the Askey-Wilson second order q-difference operator. It is then shown how to deducd a generalization of the corresponding Askey-Wilson polynomials.

A Guide to Bayesian Optimization in Bioprocess Engineering

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 4, Page 805-830, April 2026.
ABSTRACT Bayesian optimization has become widely popular across various experimental sciences due to its favorable attributes: it can handle noisy data, perform well with relatively small data sets, and provide adaptive suggestions for sequential experimentation.

Vegetational Characteristics in Natural Habitat and Population Structure of the Endangered Plant Tigridiopalma Genus

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
First comprehensive ecological assessment of the endangered genus Tigridiopalma, covering two China endemic Plant Species with Extremely Small Populations (PSESP), T. magnifica and the newly described T. exalata. T. magnifica exhibits broader habitat diversity and understory resilience, while T.

High‐Resolution Digital Terrain Model and Land‐Surface Parameters of São Sebastião and Ilhabela, Southeastern Brazil

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
The first openly accessible 2 m‐resolution lidar‐based DTM and an extensive set of land‐surface parameters (LSPs) for the region of São Sebastião and Ilhabela, southeastern Brazil, reveal geomorphological features previously indiscernible, including past landslide deposits, drainage captures and structural lineaments.

Askey-Wilson polynomials: an affine Hecke algebraic approach

open access: yes, 2000
We study Askey-Wilson type polynomials using representation theory of the double affine Hecke algebra. In particular, we prove bi-orthogonality relations for non-symmetric and anti-symmetric Askey-Wilson polynomials with respect to a complex measure.

Composite Single‐Reference and Explicitly Correlated Multireference Calculations on the Mechanism of Pyrrole Pyrolysis

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.
New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Tridiagonal Symmetries of Models of Nonequilibrium Physics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We study the boundary symmetries of models of nonequilibrium physics where the steady state behaviour strongly depends on the boundary rates. Within the matrix product state approach to many-body systems the physics is described in terms of matrices ...

Trajectories of Alcohol‐Related Problems Among First‐Year Nursing Students: Nature, Predictors, and Outcomes

open access: yesStress and Health, Volume 42, Issue 2, April 2026.
ABSTRACT This study aims to contribute to an improved dynamic person‐centred comprehension of the distinct trajectories of alcohol‐related problems observed among first‐year nursing students. Data was collected from 2963 first‐year nursing students on four occasions over the course of their first semester of professional training (3 months).
