Counting sunflowers with restricted matching number

Haixiang Zhang · Mengyu Cao · Mei Lu

For $\mathcal H\subseteq\binom{[n]}k$, let $ν(\mathcal H)$ denote its matching number and let $d_{\mathcal H}(E)$ denote the codegree of a $(k-1)$-set $E$. We study the codegree moments $ co_p(\mathcal H)=\sum_{E\in\binom{[n]}{k-1}}d_{\mathcal H}(E)^p $ and the number of copies of the $k$-uniform $l$-petal sunflower $S...

Filtered Boolean powers of finite simple non-abelian Mal'cev algebras

Peter Mayr · Nik Ruškuc

Let $\mathbf{A}$ be a finite simple non-abelian Mal'cev algebra (e.g. a group, loop, ring). We investigate the Boolean power $\mathbf{D}$ of $\mathbf{A}$ by the countable atomless Boolean algebra $\mathbf{B}$ filtered at some idempotents $e_1,\dots,e_n$ of $\mathbf{A}$. When $e_1,\dots,e_n$ are all idempotents of $\mat...

Mining and engineering of active PB transposons in Hymenoptera

Wang, Bingqing · Gao, Bo · Wang, Quan · Xiang, Kuilin · y 3 más

PiggyBac (PB) transposons, such as the canonical transposon from Trichoplusia ni and the more recently discovered Mage from Lepidoptera, are "cut-and-paste" mobile genetic elements widely harnessed as non-viral vector systems for gene therapy and transgenesis. Despite the ecological and economic significance of the ins...

Using 19F NMR to quantify enthalpy-entropy compensation in protein-protein interactions

Thomas W. Redvanly · Gary J. Pielak

Protein structural, stability, and functional equilibria are sensitive to the solution environment and governed by enthalpic and entropic contributions. NMR spectroscopy of suitably labeled- or isotopically enriched-samples provides a powerful tool for quantifying protein reactions in solution. Here we apply 19F NMR da...

Synaptic remodeling and functional recovery: Huan Le Ning decoction mitigates perimenopausal anxiety and depression symptoms via hippocampal reorganization

Xian Ma · Yujie Xu · Yu Bi · Lu Yang · y 5 más

Huan Le Ning Decoction is a traditional Chinese medicinal formula empirically used to alleviate perimenopausal emotional disturbances. Despite its clinical application, the neurobiological mechanisms remain unclear.Building on prior network pharmacology predictions that prioritized NOTCH1, NID2, and PTGDS as putative t...

Super Yangians in characteristic 2

Hao Chang · Hongmei Hu

We define the super Yangian $Y_{m|n}$ over a field $\mathbbm{k}$ of characteristic $2$, and show that the super Yangian $Y_{m|n}$ is a deformation of the super universal enveloping algebra of the current Lie algebra $\mathfrak{gl}_{m+n}[t]$. By employing the methods of the work of \cite{BT18}, we also give a descriptio...

Recurrence and coefficient inequality for the partial Petrial polynomial of graphs

Feng, Ruiqing · Guo, Xia · Yan, Qi

The partial Petrial polynomial of a ribbon graph, introduced by Gross, Mansour and Tucker, enumerates partial Petrials by Euler genus. Recently, Deng, Jin and Yan defined an analogue for grafts and showed that it can be expressed as a rank-generating function of an adjacency matrix. In this paper we first prove a recur...

Testing and characterization of wafer-scale MAPS prototypes for the ALICE ITS3 upgrade

Nicolas Tiltmann

The ALICE experiment will upgrade the innermost three layers of its vertexing detector, the Inner Tracking System (ITS), during the next LHC Long Shutdown (LS3) with a novel, bent, ultra-light MAPS-based tracker. Six wafer-scale sensor chips will be bent into three cylinders, held in place only by carbon foam, leaving...

First molecularly supported detection of Oochoristica sp. (Cestoda: Anoplocephalidae) in a Yucatán spiny-tailed iguana (Cachryx defensor) from Italy: A case report

Allievi, Carolina · Cafiso, Alessandra · De Filippo, Nicholas · Lubian, Emanuele · y 4 más

During a parasitological investigation conducted in Italy on domestic reptiles, a motile proglottid was macroscopically observed in a fecal sample from a Yucatán spiny-tailed iguana (Cachryx defensor). Subsequent analysis using the quali-quantitative flotation technique (Mini-FLOTAC®) revealed the presence of cestode e...
