Banded versus Single-sided bonded space maintainers: A Comparative Study

open access: yesIndian Journal of Dental Sciences, 2018
Background: The present study is conducted to evaluate and compare the clinical performance of conventional band and loop space maintainer and fiber reinforced composite resin (FRCR) space maintainers.

Closed-loop control of k-space sampling via physiologic feedback for cine MRI.

open access: yesPLoS ONE, 2020
BackgroundSegmented cine cardiac MRI combines data from multiple heartbeats to achieve high spatiotemporal resolution cardiac images, yet predefined k-space segmentation trajectories can lead to suboptimal k-space sampling. In this work, we developed and

On the effective action for scalars in a general manifold to any loop order

open access: yesPhysics Letters B, 2023
Functional methods and a derivative expansion are employed for laying out a procedure to compute the effective action to any loop order, for scalar fields parametrising an arbitrary Riemannian manifold, while maintaining explicit field-space covariance ...

Curved Flats, Pluriharmonic Maps and Constant Curvature Immersions into Pseudo-Riemannian Space Forms

open access: yes, 2006
We study two aspects of the loop group formulation for isometric immersions with flat normal bundle of space forms. The first aspect is to examine the loop group maps along different ranges of the loop parameter.

L-infinity spaces and derived loop spaces

open access: yes, 2014
We develop further the approach to derived differential geometry introduced in Costello's work on the Witten genus. In particular, we introduce several new examples of L-infinity spaces, discuss vector bundles and shifted symplectic structures on L-infinity spaces, and examine in some detail the example of derived loop spaces.

Finite loop spaces are manifolds

open access: yesActa Mathematica, 2004
The purpose of this work is to show the following result: Theorem: Let \(B\) be a CW-complex and denote by \(X\) the loops on \(B\), \(\Omega B\). If \(H_*(X)=\bigoplus _i H_i(X)\) is a finitely generated abelian group, then \(X\) is homotopy equivalent to a compact, smooth parallelizable manifold.

On loop spaces of configuration spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 2002
This article gives an analysis of topological and homological properties for loop spaces of configuration spaces. The main topological results are given by certain choices of product decompositions of these spaces, as well as “twistings" between the factors.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Numerical integration of loop integrals through local cancellation of threshold singularities

open access: yesJournal of High Energy Physics, 2022
We propose a new approach that allows for the separate numerical calculation of the real and imaginary parts of finite loop integrals. We find that at one-loop the real part is given by the Loop-Tree Duality integral supplemented with suitable ...

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

open access: yesFEBS 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 ...
