Perturbative four-point functions in planar N = 4 $$ \mathcal{N}=4 $$ SYM From hexagonalization

Journal of High Energy Physics, 2019
We use hexagonalization to compute four-point correlation functions of long BPS operators with special R-charge polarizations. We perform the computation at weak coupling and show that at any loop order our correlators can be expressed in terms of single

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Loop-check free sequent calculi for unary fragment of temporal logic

Lietuvos Matematikos Rinkinys
This paper explores the construction of an efficient sequent calculus for a selected fragment of porpositional linear temporal logic (PLTL), extending the ideas of classical calculi discussed in [1], and builds upon previous investigations into the ...

Resummation of Goldstone Infrared Divergences: A Proof to All Orders [PDF]

, 2017
The perturbative effective potential calculated in Landau gauge suffers from infrared problems due to Goldstone boson loops. These divergences are spurious and can be removed by a resummation procedure that amounts to a shift of the mass of soft ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Sampling Loop Test Check Evaluation of Secondary System based on VAE-WSVM Data Mining

Zhongguo dianli
Analyze the hidden dangers existing in the sampling circuit of the secondary system, and in view of the defects that the existing methods are difficult to obtain large amount of data, based on the historical measurement data, the variational autoencoder ...

A tale of two exponentiations in N=8 supergravity

Physics Letters B, 2019
The structure of scattering amplitudes in supergravity theories continues to be of interest. Recently, the amplitude for 2→2 scattering in N=8 supergravity was presented at three-loop order for the first time.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

One loop in D = 11 vs D = 10: 4-point check

Journal of High Energy Physics
The one-loop correction to eleven-dimensional supergravity involves a cubically divergent term t 8 t 8 R 4, with four Riemann tensors. A similar term (with finite coefficient) has been argued to be present in the M-theory effective action. It is expected

Generalizing completeness results for loop checks in logic programming

Theoretical Computer Science, 1992
Loop checking is one of the fundamental problems encountered during the search of effective algorithms for logic programming. This complex problem cannot be solved in full generality (even in absence of function symbols). In \textit{R. N. Bol, K. R. Apt} and \textit{J. W. Klop} [ Theor. Comput. Sci. 86, No.
