Web-based monitoring tool of the Atlantic Ocean observing system (Europe)

Web-based service tool that monitor data flow and key performance indicators of the Atlantic observing system. The focus here is on the monitoring of European contributions, including the EuroGOOS Atlantic ROOSES

A JOURNEY FROM THE OCTONIONIC ℙ2 TO A FAKE ℙ2

We discover a family of surfaces of general type with K2 = 3 and pg = q = 0 as free C13 quotients of special linear cuts of the octonionic projective plane Oℙ2. A special member of the family has 3 singularities of type A2, and is a quotient of a fake projective plane. We use the techniques of earlier work of Borisov and Fatighenti to define this fake projective plane by explicit equations in its bicanonical embedding

Quantitative Susceptibility Mapping of Ring Lesions in Relapsing Remitting Multiple Sclerosis

Introduction: Our project evaluates the presence of and changes in susceptibility and volume of ring lesions (RLs) over a two-year time period in a series of relapsing remitting MS (RRMS) subjects, and identifies and quantifies any other parameters that correlated with EDSS score. Methods: All subjects went through 3T MR imaging at baseline and 41 subjects underwent a maximum of two follow-up scans. The imaging protocol included T2 fluid attenuated inversion recovery (FLAIR), T1-weighted imaging acquired pre and post contrast, T2-weighted turbo spin-echo (T2 TSE) and susceptibility weighted imaging (SWI) sequences, all collected in a transverse mode. SWI, FLAIR, T1- and T2-weighted images were co-registered to verify the agreement of ring lesions across all modalities. The mean and peak susceptibilities of RLs on QSM data, lesion volume on FLAIR, RL volume on T2-weighted, and inner-/outer-diameters and absolute intensity value of RLs on T2-weighted data were recorded at all available time points. Results: Quantity of ring lesions had a positive correlation with EDSS, yet lesion volume showed no such relationship. Measurements of both the entire annular ring and its section with peak susceptibility on QSM remained constant over time. On the other hand, the FLAIR lesion volume was positively correlated with EDSS. Conclusions: This work does a comprehensive analysis of ring lesions by evaluating FLAIR, QSM and T2 data across 43 patients and over multiple time points. Since several parameters regarding RL characteristics having remained relatively constant, lesion evolution at the ring periphery may be a very slow process

Cocaine-mediated induction of microglial activation involves the ER stress-TLR2 axis

Effects of PBN (ROS scavenger) and APO (NADPH oxidase inhibitor) on cocaine-induced ROS formation in BV2 cells. (A) Green fluorescence was observed using a Zeiss Observer Z1 inverted microscope (Carl Zeiss MicroImaging). It revealed that PBN and APO resulted in significant inhibition of cocaine-mediated induction of ROS production. (JPG 7600 kb

Dipolar-coupled entangled molecular 4f qubits

S.P. thanks the Novo Nordisk Foundation for research grant NNF20OC0065610. EPR Equipment funding by BBSRC to B. E. B. (17 Alert grant BB/R013780/1) is also gratefully acknowledged.We demonstrate by use of continuous wave- and pulse-electron paramagnetic resonance spectroscopy on oriented single crystals of magnetically dilute YbIII ions in Yb0.01Lu0.99(trensal) that molecular entangled two-qubit systems can be constructed by exploiting dipolar interactions between neighboring YbIII centers. Furthermore, we show that the phase memory time and Rabi frequencies of these dipolar-interaction-coupled entangled two-qubit systems are comparable to the ones of the corresponding single qubits.Publisher PDFPeer reviewe
