On a conjecture of Givental [PDF]

open access: yesJournal of Mathematical Physics, 2004
These brief notes record our puzzles and findings surrounding Givental’s recent conjecture which expresses higher genus Gromov–Witten invariants in terms of the genus-0 data. We limit our considerations to the case of a complex projective line, whose Gromov–Witten invariants are well-known and easy to compute.

An approach to Quillen's conjecture via centralisers of simple groups [PDF]

open access: yes, 2021
For any given subgroup H of a finite group G, the Quillen poset of nontrivial elementary abelian p-subgroups is obtained from by attaching elements via their centralisers in H.

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.

On a conjecture of krammer

open access: yesJournal of Combinatorial Theory, Series A, 1991
Daan Krammer made the following conjecture: \[ 1+2\sum^{\lfloor n/2\rfloor}_{k=1} {{2k-1}\brack k}_ q(-1)^ kq^{-k(k-1)/2}=\begin{cases} (n/5)&\text{ if } 5\nmid n \\ 1+4 \cos(2\pi/5) &\text{ if } 5| n,\end{cases} \] \[ \text{where } q=e^{2\pi i/n},\;(n/5)=\begin{cases} 1 &\text{ if \(n\equiv 1\) or \(4 \bmod 5\)} \\ -1 &\text{ if \(n\equiv 2\) or \(3 ...

Artin L-Functions for Abelian Extensions of Imaginary Quadratic Fields [PDF]

open access: yes, 2005
Let F be an abelian extension of an imaginary quadratic field K with Galois group G. We form the Galois-equivariant L-function of the motive h(Spec F)(j) where the Tate twists j are negative integers.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

The Honeycomb Conjecture [PDF]

open access: yesDiscrete & Computational Geometry, 2001
The classical honeycomb conjecture asserts that any partition of the plane into regions of equal area has perimeter at least that of the regular hexagonal honeycomb tiling. Pappus discusses this problem in his preface to Book V. This paper gives the first general proof of the conjecture.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Conjecturing with some Conjectures

open access: yesGlobal Journal of Science Frontier Research, 2020
This world has been seeing so many conjectures from the formation of this world. Particularly, mathematics world has been seeing so many conjectures from the civilization of this world, also venturing through on it. So many Indians, Chinese and Arabian scholars provided their participation in mathematics world.
