The R *-operation for Feynman graphs with generic numerators

open access: yesJournal of High Energy Physics, 2017
The R *-operation by Chetyrkin, Tkachov, and Smirnov is a generalisation of the BPHZ R-operation, which subtracts both ultraviolet and infrared divergences of euclidean Feynman graphs with non-exceptional external momenta.

Bootstrapping monodromy defects in the Wess-Zumino model

open access: yesJournal of High Energy Physics, 2022
We use analytical bootstrap techniques to study supersymmetric monodromy defects in the critical Wess-Zumino model. In preparation for this result we first study two related systems which are interesting on their own: general monodromy defects (no susy),

Finite quotients of groups of I-type [PDF]

open access: yesAdvances in Mathematics (2014), vol. 258, p. 46-68, 2013
To every group of $I$-type, we associate a finite quotient group that plays the role that Coxeter groups play for Artin-Tits groups. Since groups of I-type are examples of Garside groups, this answers a question of D. Bessis in the particular case of groups of I-type. Groups of $I$-type are related to finite set theoretical solutions of the Yang-Baxter

Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

open access: yesFEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Distinct dysregulated pathways in sporadic and Lynch syndrome‐associated colorectal cancer offer insights for targeted treatment

open access: yesFEBS Letters, EarlyView.
This study explores the distinct molecular mechanisms underlying Lynch syndrome‐associated and sporadic colorectal cancer (CRC). By highlighting the therapeutic potential of targeting the PI3K‐Akt pathway in Lynch syndrome‐associated CRC and the Wnt pathway in sporadic CRC, the findings open avenues for personalised treatment strategies, aiming to ...

Narrow normal subgroups of Coxeter groups and of automorphism groups of Coxeter groups [PDF]

open access: yesarXiv, 2022
By definition, a group is called narrow if it does not contain a copy of a non-abelian free group. We describe the structure of finite and narrow normal subgroups in Coxeter groups and their automorphism groups.

SOME GROUP THEORY [PDF]

open access: yesSchool Science and Mathematics, 1918
In this chapter we state (mostly without proof) some basic facts from the theory of groups. We have included only those facts from the general theory that we shall have occasion to use later — the treatment is by no means exhaustive. We refer to any standard textbook on Group Theory for more detailed accounts of the subject in general and for the ...

Immunoregulatory mechanisms of the arachidonic acid pathway in cancer

open access: yesFEBS Letters, EarlyView.
The central role of the arachidonic acid (AA) pathway in anticancer immunity. Enzymes and metabolites of the AA pathway can play both immunosuppressive and immunostimulatory roles in the tumor microenvironment. Therefore, their tailored targeting could be beneficial as a standalone therapy or in combination with current cancer immunotherapy.

Overlap singularity and time evolution in integrable quantum field theory

open access: yesJournal of High Energy Physics, 2018
We study homogeneous quenches in integrable quantum field theory where the initial state contains zero-momentum particles. We demonstrate that the two-particle pair amplitude necessarily has a singularity at the two-particle threshold.

How tropical are seven- and eight-particle amplitudes?

open access: yesJournal of High Energy Physics, 2020
We study tropical Grassmanians Tr(k, n) in relation to cluster algebras, and assess their applicability to n-particle amplitudes for n = 7, 8. In N $$ \mathcal{N} $$ = 4 super Yang-Mills theory, we first show that while the totally positive part of Tr(4,
