Nasolacrimal Duct Orifice: A Cadaveric Study in Relation to Important Anatomical Landmarks

open access: yesMedicine Science, 2014
The nasolacrimal apparatus is intimately associated with the lateral nasal wall and may be approached using an endoscopic technique. This study was undertaken to describe in detail the gross anatomy of the nasolacrimal duct orifice in relation to various

Random Access Transport Capacity [PDF]

open access: yes, 2009
We develop a new metric for quantifying end-to-end throughput in multihop wireless networks, which we term random access transport capacity, since the interference model presumes uncoordinated transmissions. The metric quantifies the average maximum rate

mRNAs and lncRNAs intrinsically form secondary structures with short end-to-end distances [PDF]

open access: yesNature Communications, 2018
Abstract The 5′ and 3′ termini of RNA play important roles in many cellular processes. Using Förster resonance energy transfer (FRET), we show that mRNAs and lncRNAs have an intrinsic propensity to fold in the absence of proteins into structures in which the 5′ end and 3′ end are ≤7 nm apart irrespective of mRNA length.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Long distance entanglement and high-dimensional quantum teleportation in the Fermi–Hubbard model

open access: yesScientific Reports, 2023
The long distance entanglement in finite size open Fermi–Hubbard chains, together with the end-to-end quantum teleportation are investigated. We show the peculiarity of the ground state of the Fermi–Hubbard model to support maximum long distance ...

Maximum-entropy calculation of the end-to-end distance distribution of force-stretched chains [PDF]

open access: yesThe Journal of Chemical Physics, 2003
Using the maximum-entropy method, we calculate the end-to-end distance distribution of the force-stretched chain from the moments of the distribution, which can be obtained from the extension-force curves measured in single-molecule experiments. If one knows the force expansion of the extension through the (n−1)th power of a force, that is enough to ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Flow trees for exploring spatial trajectories [PDF]

open access: yes, 2009
A trajectory is a directed path that defines a link between two spatial locations. That path may be as simple as the Euclidean shortest distance between a start and end point, or may involve a more complex traversal through time and space to travel from ...
