Vectorizing and distributing number‐theoretic transform to count Goldbach partitions on Arm‐based supercomputers

Concurrency Computation Practice and Experience, 2023
Summary In this article, we explore the usage of scalable vector extension (SVE) to vectorize number‐theoretic transforms (NTTs). In particular, we show that 64‐bit modular arithmetic operations, including modular multiplication, can be efficiently implemented with SVE instructions.

Goldbach partitions and norms of cusp forms

Journal of Numerical Analysis and Approximation Theory, 2019
An integral formula for the Goldbach partitions requires uniform convergence of a complex exponential sum. The dependence of the coefficients of the series is found to be bounded by that of cusp forms.

On the existence of a non-zero lower bound for the number of Goldbach partitions of an even integer

International Journal of Mathematics and Mathematical Sciences, 2004
The Goldbach partitions of an even number, given by the sums of two prime addends, form the nonempty set for all integers 2n with 2≤n≤2×1014. It will be shown how to determine by the method of induction the existence of a non-zero lower bound for the

Multiplicative irreducibility of shifted multiplicative subgroups

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract In a recent breakthrough, Kalmynin resolved conjectures of Lev–Sonn and Sárközy on additive decompositions of multiplicative subgroups of prime fields. In this paper, inspired by a related conjecture of Sárközy, we prove multiplicative analogues of Kalmynin's results. We show that for every proper multiplicative subgroup G$G$, the shifted set (

Methane Emissions From Flame Curtain Pyrolysis (Kon‐Tiki)

GCB Bioenergy, Volume 18, Issue 4, April 2026.
Flame curtain pyrolysis enables decentralized biochar production, but its net climate benefit depends on the magnitude of methane emissions caused during production. Methane emissions were below 5 g CH4 kg−1 biochar for dry feedstocks but increased for moist feedstocks. Pyrolysis emitted less methane than open burning of wheat straw. ABSTRACT Pyrogenic

Effects of temporal and spatial variability in energy fluxes on phytoplankton

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Uganda

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Geomechanics of Flooding‐Induced Microseismicity—Implications for Post‐Mining Environments

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Seismicity related to mining has gained considerable public attention in the last decades and is one of the reasons for mine closures in Germany. The seismicity in the Ruhr coal mining district of Germany has been monitored by different regional and (temporal) local networks and is classified as purely mining‐induced without evidence for ...

“Be Open to All Those Ways That People Can Live Their Lives:” LGBTQ+ Client Recommendations for Adapting Emotionally Focused Couple Therapy

Journal of Marital and Family Therapy, Volume 51, Issue 3, July 2025.
ABSTRACT Emotionally focused couple therapy (EFCT) is an empirically supported treatment for relationship distress. Yet, despite EFCT's substantial evidence base, to date, there have been no studies that have integrated LGBTQ+ clients' experiences and therapeutic needs into the EFCT process.

Foliar Water Uptake Supports Water Potential Recovery but Does Not Affect Xylem Sap Composition in Two Salt‐Secreting Mangroves

Plant, Cell &Environment, Volume 48, Issue 5, Page 3027-3037, May 2025.
ABSTRACT Mangroves are highly salt‐tolerant species, which live in saline intertidal environments, but rely on alternative, less saline water to maintain hydraulic integrity and plant productivity. Foliar water uptake (FWU) is thought to assist in hydration of mangroves, particularly during periods of acute water deficit.
