Mechanistic Insights into a Chiral Phosphoric Acid-Catalyzed Asymmetric Pinacol Rearrangement
The first catalytic enantioselective pinacol rearrangement was reported by Antilla and co-workers in 2010. The reaction was catalyzed by a chiral phosphoric acid and resulted in high levels of enantioselectivity (up to 96% ee)....
Minimal configurations and sandpile measures
We give a new simple construction of the sandpile measure on an infinite graph G, under the sole assumption that each tree in the Wired Uniform Spanning Forest on G has one end almost surely. For so called generalized minimal...

Heart-brain integration dynamics are critical for interoception (i.e. the sensing of body signals). In this unprecedented longitudinal study, we assessed neurocognitive markers of interoception in patients who underwent...

The subjective metric of remembered colors
In order to explore the metric structure of the space of remembered colors, a computer game was designed, where players with normal color vision had to store a color in memory, and later retrieve it by selecting the best match...
Optimizing subgroup selection in two-stage adaptive enrichment and umbrella designs.
Nicolás M Ballarini, Thomas Burnett, Thomas Jaki, Christoper Jennison, Franz König, Martin Posch
May 09, 2021
We design two-stage confirmatory clinical trials that use adaptation to find the subgroup of patients who will benefit from a new treatment, testing for a treatment effect in each of two disjoint subgroups. Our proposal allows...
Relationship Between Brain Pulsatility and Cerebral Perfusion Pressure
Leanne A Calviello, Nicolás de Riva, Joseph Donnelly, Marek Czosnyka, Peter Smielewski, David K Menon, Frederick A Zeiler
Aug 08, 2017
BACKGROUND: Determination of relationships between transcranial Doppler (TCD)-based spectral pulsatility index (sPI) and pulse amplitude (AMP) of intracranial pressure (ICP) in 2 groups of severe traumatic brain injury (TBI)...

OBJECTIVE: Mathematical modeling of cerebral hemodynamics by descriptive equations can estimate the underlying pulsatile component of cerebral arterial blood volume (CaBV). This way, clinical monitoring of changes in cerebral...

Self-healing concrete has the potential to optimise traditional design approaches; however, commercial uptake requires the ability to harmonize against standardized frameworks. Within EU SARCOS COST Action, different...
Human Cytomegalovirus Long Non-coding RNA1.2 Suppresses Extracellular Release of the Pro-inflammatory Cytokine IL-6 by Blocking NF-κB Activation
Betty Lau, Karen Kerr, Quan Gu, Katie Nightingale, Robin Antrobus, Nicolás M. Suárez, Richard J. Stanton, Eddie C. Y. Wang, Michael P. Weekes, Andrew J. Davison
Aug 05, 2020
Long non-coding RNAs (lncRNAs) are transcripts of >200 nucleotides that are not translated into functional proteins. Cellular lncRNAs have been shown to act as regulators by interacting with target nucleic acids or proteins and...
Optimal Cheeger cuts and bisections of random geometric graphs
Let d ≥ 2. The Cheeger constant of a graph is the minimum surfaceto- volume ratio of all subsets of the vertex set with relative volume at most 1/2. There are several ways to define surface and volume here: The simplest...

The Autonomic Nervous System Pulls the Strings to Coordinate Circadian HSC Functions.
As for many other adult stem cells, the behavior of hematopoietic stem and progenitor cells (HSPCs) is subjected to circadian regulatory patterns. Multiple HSPC functions, such as proliferation, differentiation or trafficking...

Direct procurement of donor heart with normothermic regional perfusion of abdominal organs.
Prashant N Mohite, Diana García Sáez, Andrew J Butler, Christopher JE Watson, Andre Simon
May 03, 2019
PURPOSE: To evaluate if direct procurement of heart is possible in combination with normothermic regional perfusion of abdominal organs in donors after circulatory death. DESCRIPTION: A donation after circulatory death pathway...
