Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

TAXON, EarlyView.
Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

On certain classes of Dirichlet series with real coefficients absolute convergent in a half-plane

Математичні Студії
For $h>0$, $\alpha\in [0,h)$ and $\mu\in {\mathbb R}$  denote by   $SD_h(\mu, \alpha)$ a class of absolutely convergent in the half-plane $\Pi_0=\{s:\, \text{Re}\,s\alpha$ for all $s\in \Pi_0$,}   \smallskip\noi and let  $\Sigma D_h(\mu, \alpha)$ be ...

Real roots of Dirichlet 𝐿-series [PDF]

Bulletin of the American Mathematical Society, 1949
Verf. betrachtet \(L(s,\chi)\), wobei \(\chi\) eine reeller Charakter mod \(k\), aber nicht Hauptcharakter ist. Es wird gezeigt, daß \(L(s,\chi)\ne 0\) für reelles positives \(s\) und \(2\le k\le 67\). Die Methoden des Verf. sind nach seinen Angaben auch für \(67\le k\le 227\) anwendbar, mit Ausnahme von \(k = 148\) und \(k = 163\). Diese Ausnahmefälle

Unsupervised Work Behavior Pattern Extraction Based on Hierarchical Probabilistic Model

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
In this study, we address the challenge of analyzing worker behaviors in high‐mix, low‐volume production environments, where traditional supervised learning methods struggle owing to the lack of labeled data and task variability among workers. To overcome these issues, we propose a novel hierarchical approach for unsupervised behavior pattern ...

On mean square of the error term of a multivariable divisor function

AIMS Mathematics
Let $ \tau(n) $ be the Dirichlet divisor function and $ k\geqslant2 $ be a fixed integer. We give an asymptotic formula of the mean square of$ \begin{equation*} \Delta_k(x) = \sum\limits_{n_1, \cdots, n_k\leqslant x}\tau(n_1 \cdots n_k)-x^kP_k(\log x ...

Quantitative Evaluation of Mechanical Defects for Circuit Breakers Based on Self‐Adaptive Fault Feature Tracking

High Voltage, EarlyView.
ABSTRACT Many researchers are committed to improving the diagnosis accuracy and solving the few‐shot problem on circuit breakers (CBs). However, the research on the vibration transmission mechanism of the fault is insufficient, which makes it difficult to find the potential design defects of CBs through vibration.

Cohorts of immature Pteropus bats show interannual variation in Hendra virus serology

Journal of Animal Ecology, EarlyView.
Pteropus bat with offspring, photo taken by Manuel Ruiz‐Aravena. Abstract Understanding the drivers of seasonal disease outbreaks remains a fundamental challenge in disease ecology. Periodic outbreaks can be driven by several seasonally varying factors, including pulses of susceptible individuals through births, changes in host behaviour and social ...

Measuring MAN (incorporating JRAI): Computational anthropological analysis and quantitative speculation

Journal of the Royal Anthropological Institute, EarlyView.
Abstract In this paper, we present a foray into the computational study of anthropological texts. Drawing on a corpus of approximately 2,500 articles published in the Journal of the Royal Anthropological Institute (formerly Man) from 1950 to 2018, we discuss selected findings from the deployment of two methods for computational text analysis, namely ...
