Novel L5-S1 interbody fusion technique for root anomalies or abnormal root configurations of L5-S1 foramens

open access: yesJournal of Craniovertebral Junction and Spine, 2018
Purpose: We show in this study that if a root anomaly does not permit access to the disc space in the usual way, the technique we define here can be used.

Valuations and tensor weight on polytopes [PDF]

open access: yes, 2006
Let V be a finite-dimensional vector space over a square-root closed ordered field F (this restriction permits an inner product with corresponding norm to be imposed on V)

Weight Spaces and Root Spaces of Kac-Moody Algebras

open access: yesJournal of Algebra, 1994
Let \({\mathfrak g} (A)\) be the Kac-Moody algebra associated to a symmetric generalized Cartan matrix. The purpose of the paper under review is to give an explicit realization of the weight spaces of an integrable highest weight \({\mathfrak g} (A)\)-module \(L(\lambda)\) and the weight spaces of the universal enveloping algebra \(U({\mathfrak n}_ -)\)

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The role of the equation of state and the space-time dimension in spherical collapse

open access: yes, 2003
We study the spherically symmetric collapse of a fluid with non-vanishing radial pressure in higher dimensional space-time. We obtain the general exact solution in the closed form for the equation of state ($P_r = \gamma \rho$) which leads to the ...

Insertion of Continuous Real Functions on Spaces, Bispaces, Ordered Spaces and Pointfree Spaces—A Common Root [PDF]

open access: yesApplied Categorical Structures, 2009
A biframe is a triple consisting of a frame (called the total part of the biframe) and two subframes which together generate the total part. In the same way that a frame has its co-frame of sublocales which can be made into a frame by reverse inclusion, a biframe also has what could informally be called a ``biframe of sublocales''. For a given biframe,

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Magnetic resonance imaging in the evaluation of different compression locations in patients with cervical spondylotic radiculopathy

open access: yesJournal of Orthopaedic Surgery and Research
Objective Studies showed that T2-weighted turbo spin-echo SPACE (T2-SPACE) could be superior to conventional two-dimensional magnetic resonance imaging (2D MRI) to detect the locations of nerve root compression.

Tracking excited states in wave function optimization using density matrices and variational principles [PDF]

open access: yes, 2019
We present a method for finding individual excited states' energy stationary points in complete active space self-consistent field theory that is compatible with standard optimization methods and highly effective at overcoming difficulties due to root ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
