Homotopy theory and distributed computing

Theriault, Stephen · Liu, Xingwu · Wu, Jie · Yue, Yunguang

Algebraic topology has proved to be a very useful tool in addressing the computability of rendezvous problems in distributed computing. To date the tools used include the fundamental group and ordinary homology. This paper introduces more sophisticated techniques from homotopy theory involving the Hilton-Milnor Theorem...

High pressure study of the interplay between charge and magnetic ortdering in SmNiC2

Arthur VON UNGERN-STERNBERG SCHWARK · Mark Joachim GRAF VON WESTARP · Gaston GARBARINO · Sofia Michaela SOULIOU

Charge density wave (CDW) ordering in SmNiC2 is followed at lower temperatures by the ferromagnetic (FM) ordering of the Sm moments. Below the FM onset, the CDW order is fully suppressed, evidencing a strong interplay between the two types of ordering. The CDW suppression was attributed to the weakening of the Fermi su...

Deformation in the Earth’s crust localizes onto faults that may rupture rapidly producing earthquakes, or undergo slow aseismic slip that may or may not accelerate into coseismic slip. Our goal is to provide the first quantitative laboratory observations of the full displacement field in rocks before and during coseism...

Beyond numbers: working memory deficits in children with mathematical difficulties — A longitudinal meta-analysis

Andrea, Kósa · Liviu-Andrei, Fodor

Working memory (WM) is central to mathematical development, yet its role in children with mathematical difficulties (MD) remains debated. Using a multilevel approach, this longitudinal meta-analysis synthesized 36 studies (38 samples; N = 6,015) comparing WM in children with MD and typically developing peers. Across 65...

Botrytis cinerea impact on copper-spatial distribution and speciation in grapevine leaves exposed to copper-based nanoformulations

Astrid AVELLAN · Diana SALVADOR · Sandra RODRIGUES · Hiram CASTILLO · y 1 más

The usage of Cu-based fungicides in agriculture is restricted in the EU (EU 2018/1981) due to soil contamination. There is an urgent need to enhance the efficiency of the allowed Cu dosages. Cu-based nanoparticles (Cu-NPs) can be an efficient fungicide alternative. They present higher leaf affinity than ionic Cu, drast...

The bidding games: Reinforcement learning for MEV extraction on Polygon blockchain

Andrei Seoev · Leonid Gremyachikh · Anastasiia Smirnova · Yash Madhwal · y 7 más

In blockchain networks, the strategic ordering of transactions within blocks has emerged as a significant source of profit extraction, known as Maximal Extractable Value (MEV). The transition from spam-based Priority Gas Auctions (PGA) to structured auction mechanisms like Polygon Atlas has transformed MEV extraction f...

Online Ramsey numbers of ordered graphs

Emily Heath · Dylan King · Grace McCourt · Hannah Sheats · y 1 más

The online ordered Ramsey game is played between two players, Builder and Painter, on an infinite sequence of vertices with ordered graphs $(G_1,G_2)$, which have linear orderings on their vertices. On each turn, Builder first selects an edge before Painter colors it red or blue. Builder's objective is to construct eit...

Nanoscale localisation of memantine governs structural modulation and loading in bicontinuous cubic phase systems

Lucrezia, Guarneri · Chia, Beh · Liliana, de Campo · Andrew E, Whitten · y 5 más

Memantine is a primary pharmacological treatment for moderate-to-severe Alzheimer's disease but its efficacy and brain delivery remain limited. Lipid bicontinuous cubic phases and their nanoparticle dispersions (cubosomes) offer platforms for enhancing central nervous system drug delivery, yet the rigid adamantane scaf...

Unraveling the role of the precursors and the nucleation and growth mechanisms during lead halides perovskites nanocrystals formation by SAX

Yuliia BEREZOVSKA · Federica BERTOLOTTI · Simon BÖHME · Stefano CHECCHIA · y 3 más

The recently developed slow room-temperature synthesis of lead halide perovskite nanocrystals (LHP NCs) has provided an opportunity to study their growth mechanism in situ. However, the reaction pathway from molecular precursors to nuclei remains unclear. This project aims to: (i) determine whether LHPs precursors (PbB...

Impact of Modified Anastomosis Sequence on Warm Ischemic Time and Clinical Outcomes in Orthotopic Heart Transplantation

Joon Young Kim · EunJi Kim · Hong Rae Kim · Sung-Ho Jung · y 2 más

Prolonged ischemic time adversely affects outcomes after orthotopic heart transplantation (OHT). We implemented a modified anastomosis sequence to reduce warm ischemic time (WIT) and evaluated its impact on myocardial preservation and clinical outcomes.We retrospectively analyzed 273 OHT recipients who underwent either...
