The Role of the St. Anna Trough in Atlantic Water Transport Into the Arctic Ocean: A Novel Radiogenic Isotope Assessment Using Iodine, Uranium, and Neodymium

Journal of Geophysical Research: Oceans, Volume 130, Issue 4, April 2025.
Abstract The St. Anna Trough (SAT) plays a critical role in Arctic Ocean circulation by facilitating heat and water mass exchange, influencing sea‐ice melt and thermohaline dynamics. However, ocean circulation in this key region remains understudied compared to other parts of the Arctic.

Testing the Ce Limit of Mass Bias Correction Using 145Nd/142Nd as Normalizing Ratio in Radiogenic Neodymium Isotope Analysis by MC‐ICP‐MS

Rapid Communications in Mass Spectrometry, Volume 39, Issue 3, 15 February 2025.
ABSTRACT Rationale Neodymium isotopes are a powerful geochemical tool that has widely been used in terrestrial and extraterrestrial studies. Modern multicollector inductively coupled plasma mass spectrometers (MC‐ICP‐MS) allow fast, accurate, and precise analysis of the radiogenic Nd isotope ratio 143Nd/144Nd.

Fractal Operators Abstracted from Arterial Blood Flow

Fractal and Fractional
In this paper, we present a re-established functional fractal circuit model of arterial blood flow that incorporates the shunt effect of the branch vessels. Under the background of hemodynamics, we abstracted a family of fractal operators and investigate

Images for the Y‐Function via Marichev–Saigo–Maeda Fractional Integration and Differentiation Operators

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
The Y‐function has emerged as a significant tool in generalized fractional calculus due to its ability to unify and extend numerous classical special functions and hypergeometric‐type functions. Applying the Marichev–Saigo–Maeda fractional integration and differentiation operators of any complex order to the Y‐function, this study establishes four ...

A New q‐Integral Operator Containing Generalized q‐Mittag‐Leffler Function

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
In this study, we employ the mathematical framework of q‐calculus to introduce a novel integral operator that incorporates the generalized q‐Mittag‐Leffler function. Following this introduction, we delve into an in‐depth analysis of several significant properties and potential applications of this integral operator. Additionally, we explore a number of

Seawater Lead Isotopes Record Early Miocene to Modern Circulation Dynamics in the Pacific Sector of the Southern Ocean

Paleoceanography and Paleoclimatology, Volume 39, Issue 12, December 2024.
Abstract The Antarctic Circumpolar Current (ACC) is Earth's largest current flowing around Antarctica at all depths and connecting major ocean basins, thus representing an important component of Earth's climate. However, the timing and key controls determining ACC flow path and its strength as a function of past climatic boundary conditions that ...

Certain Geometric Investigations of Three Normalized Bessel-Type Functions of a Complex Variable

Mathematics
We recall the normalized forms for the three Bessel-type functions; these functions are the Bessel function, Lommel function, and Struve function of the first kind. By using convolution, we define normalized forms.
