Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Divisibility of Dynamical Maps: Schrödinger Versus Heisenberg Picture

open access: yesPRX Quantum
Divisibility of dynamical maps is a central notion in the study of quantum non-Markovianity, providing a natural framework to characterize memory effects via time-local master equations.

On a divisibility problem [PDF]

open access: yesMathematica Bohemica, 2019
Let $p_1, p_2, \cdots$ be the sequence of all primes in ascending order. Using explicit estimates from the prime number theory, we show that if $ k \geq5 $, then (p_{k+1}-1)! \mid(\tfrac12 (p_{k +1} - 1))! p_ k!, which improves a previous result of

Evaluation of gene editing in CHO cells using the Cas‐CLOVER system

open access: yesBiotechnology Progress, EarlyView.
Abstract Recent advances in gene editing technologies have transformed the genetic engineering of Chinese hamster ovary (CHO) hosts, enabling the development of cell lines with improved stability and productivity. In this study, we employed the programmable nuclease (PN) Cas‐CLOVER to precisely target the Glutamine synthetase (GS) locus in CHO cells. A

Enhancing Plateau Capacity of Binder‐Free and Self‐Supported Napkin‐Based Hard Carbon Anodes for Sodium‐Ion Batteries Via a Pre‐Oxidation Modulation Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Precise regulation of preoxidation time and carbonization temperature in biomass napkin‐derived hard carbon generates abundant closed pores and ultramicropores, significantly enhancing the capacity in the low‐potential plateau region (the high plateau capacity of 266 mAh g−1) and thereby achieving highly reversible sodium‐ion storage (395 mAh g−1 at 30

Moderate Deviation Principles for Lacunary Trigonometric Sums

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT Classical works of Kac, Salem, and Zygmund, and Erdős and Gál have shown that lacunary trigonometric sums despite their dependency structure behave in various ways like sums of independent and identically distributed random variables. For instance, they satisfy a central limit theorem (CLT) and a law of the iterated logarithm.

Deep‐Learning‐Based Image Reconstruction to Improve End‐Diastolic and Systolic Cardiac T1 Mapping

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an image reconstruction method that enables increased spatial resolution cardiac T1 mapping in both the end‐diastolic and systolic phase, that shows high T1 agreement with the clinical standard. The resolution gain is achieved by increasing the acceleration rate of MOLLI single‐shot images to R = 4, while maintaining a ...

Analogies and differences between the logic behind statistical hypothesis testing and proofs by contradiction: What can we learn from them?

open access: yesTeaching Statistics, EarlyView.
Abstract Statistical hypothesis testing (SHT) is widely employed across numerous scientific disciplines, and a clear understanding of its underlying logic is essential for the broader scientific community. Here, drawing upon both epistemological and statistical perspectives, we aim to clarify—primarily for educational purposes—the logical relationship ...

Divisibility of the sums of the power of consecutive integers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We study the divisibility of the sums of the odd power of consecutive integers, S(m,k)=1ᵐᵏ+2ᵐᵏ+...+kᵐᵏ and 1ᵏ+2ᵏ+...+nᵏ for odd integers m and k, by using the Girard-Waring identity. Faulhaber's approach for the divisibilities is discussed.
