Sport, Agency and Pigeon Snaring in the Ancient Tongan Chiefdom

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Pigeon snaring was an élite sport in the traditional Tongan chiefdom, undertaken on purpose‐built mounds known as sia heu lupe. LiDAR imagery combined with field survey and mound documentation on the island of Tongatapu has identified a comprehensive corpus of these sites.

The Sobolev-type equations of the second order with the relatively dissipative operator pencils

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
Of concern is the Cauchy problem for the Sobolev-type equation of the second order. We introduce the definition of relatively dissipative operator pencils, generalize the notion of dissipativity and relative dissipativity of operators.

Non-compact perturbations of $m$-accretive operators in general Banach spaces [PDF]

open access: yes, 1992
summary:In this paper we deal with the Cauchy problem for differential inclusions governed by $m$-accretive operators in general Banach spaces. We are interested in finding the sufficient conditions for the existence of integral solutions of the problem $

Accretive and Sectorial Extensions of Nonnegative Symmetric Operators [PDF]

open access: yesComplex Analysis and Operator Theory, 2011
\textit{J. von Neumann} in his famous article [Math. Ann. 102, 49--131 (1929; JFM 55.0824.02)] created a theory of self-adjoint extensions of a given symmetric operator on some Hilbert space. \textit{M. Krein} [Mat. Sb., N. Ser. 20(62), 431--495 (1947; Zbl 0029.14103)] gave a description of all nonnegative self-adjoint extensions of a nonnegative ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Stable Perturbed Iterative Algorithms for Solving New General Systems of Nonlinear Generalized Variational Inclusion in Banach Spaces

open access: yesAbstract and Applied Analysis, 2014
We introduce and study a new general system of nonlinear variational inclusions involving generalized m-accretive mappings in Banach space. By using the resolvent operator technique associated with generalized m-accretive mappings due to Huang and Fang ...

Zeros of accretive operators

open access: yesManuscripta Mathematica, 1974
In the investigation of accretive operators in Banach spaces X, the existence of zeros plays an important role, since it yields surjectivity results as well as fixed point theorems for operators S such that I-S is accretive.

Ishikawa and Mann Iteration Methods with Errors for Nonlinear Equations of the Accretive Type

open access: yes, 1997
LetEbe anarbitrary Banach spaceandT:E→Ea Lipschitz strongly accretive operator. It is proved that for a givenf∈E, the Ishikawa and the Mann iteration methods with errors introduced by18converge strongly to the solution of the equationTx=f.

An iterative algorithm for generalized nonlinear variational inclusions with relaxed strongly accretive mappings in Banach spaces [PDF]

open access: yes, 2003
We use Nadler’s theorem and the resolvent operator technique form-accretive mappings to suggest an iterative algorithm for solving generalized nonlinear variational inclusions with relaxed strongly accretive mappings in Banach spaces.

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).
