Brauer characters with cyclotomic field of values

open access: yesJournal of Pure and Applied Algebra, 2008
In earlier work [Math. Ann. 335, No. 3, 675-686 (2006; Zbl 1106.20006)], the first two authors proved that for any odd prime \(p\), every finite group of even order has a non-trivial rational-valued irreducible \(p\)-Brauer character. For \(p=2\) it is known that this is false for all groups \(L_2(3^{2f+1})\) (\(f=1,2,\dots\)).

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

On Hilbert divisors of Brauer characters

open access: yesJournal of Algebra, 2020
Let \(G\) be a finite group with Sylow \(p\)-subgroup of order \(p^{a}\). Let \(\text{IBr}_{p}(G)\) and \(\text{IBr}_{p}(B)\) be the sets of irreducible \(p\)-Brauer characters of \(G\) and of a \(p\)-block \(B\) of \(G\), respectively, and let \(G_{p^{\prime}}\) denote the set of \(p^{\prime}\)-elements of \(G\). The Brauer characters take values in a

The Swanscombe fossil at 90: revisiting its phylogeny, taxonomy, and place in human origins Le fossile de Swanscombe, 90 ans après : retour sur sa place phylogénique, taxonomique et dans les origines de l'humanité

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

‘CLOSING THE CARBON LOOP’: Climate Policy Discourses and the Material Politics of Municipal Waste‐to‐Biofuel Programs

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Waste‐to‐biofuel (WTB) programs have gained popularity as a municipal circular economy and an emissions reduction strategy. The upgrading of biofuels to renewable natural gas (RNG) has drawn particular interest, as RNG can displace conventional fossil fuels in any existing natural gas end use and be delivered through existing pipeline ...

Sylow Normalizers and Brauer Character Degrees

open access: yesJournal of Algebra, 2000
Let \(p\) and \(q\) be primes and let \(G\) be a finite \(\{p,q\}\)-solvable group. Let \(P\) be a Sylow \(p\)-subgroup of \(G\) and \(Q\) a Sylow \(q\)-subgroup of \(G\). Let \(N_G(P)\) and \(N_G(Q)\) denote the normalizers in \(G\) of these subgroups. The main result of the paper under review is the following.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

p-Parts of Brauer character degrees

open access: yesJournal of Algebra, 2014
Let \(G\) be a finite group and \(p\) be an odd prime. The authors prove the following results. Theorem A. Suppose that the degrees of all nonlinear irreducible \(p\)-Brauer characters of \(G\) are divisible by \(p\). If \(p\geq 5\), then \(G\) is solvable; and if \(p=3\) and the \(p\)-parts of the degrees of nonlinear irreducible \(p\)-Brauer ...

Circulating Musclin is associated with skeletal muscle function and subclinical cardiac dysfunction in patients with cancer

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Musclin (osteocrin) is a skeletal muscle‐derived peptide that has been implicated in cardioprotective signalling pathways. Its relevance in cancer patients, who frequently experience muscle wasting and cardiotoxicity, remains unclear. This study aimed to determine whether circulating Musclin levels reflect functional capacity and

Groups with two real Brauer characters

open access: yesJournal of Algebra, 2007
The structure of a finite group with exactly two conjugacy classes of real elements was described by \textit{S. Iwasaki} [in Arch. Math. 33, 512-517 (1980; Zbl 0433.20014)]. In particular, such groups have a normal Sylow \(2\)-subgroup. In the present paper, the authors study the structure of finite groups with exactly two real valued irreducible ...
