| 1 | Machine-learned interatomic potentials by active learning:amorphous and liquid hafnium dioxide显示文摘We propose an active learning scheme for automatically sampling a minimum number of uncorrelated configurations for fitting the Gaussian Approximation Potential(GAP).Our active learning scheme consists of an unsupervised machine learning(ML)scheme coupled with a Bayesian optimization technique that evaluates the GAP model.We apply this scheme to a Hafnium dioxide(HfO2)dataset generated from a“melt-quench”ab initio molecular dynamics(AIMD)protocol.Our results show that the active learning scheme,with no prior knowledge of the dataset,is able to extract a configuration that reaches the required energy fit tolerance.Further,molecular dynamics(MD)simulations performed using this active learned GAP model on 6144 atom systems of amorphous and liquid state elucidate the structural properties of HfO2 with near ab initio precision and quench rates(i.e.,1.0 K/ps)not accessible via AIMD.The melt and amorphous X-ray structural factors generated from our simulation are in good agreement with experiment.In addition,the calculated diffusion constants are in good agreement with previous ab initio studies. | Ganesh Sivaraman Anand Narayanan Krishnamoorthy Matthias Baur Christian Holm Marius Stan Gábor Csányi Chris Benmore Álvaro Vázquez-Mayagoitia | 2020 | npj Computational Materials2020，，1： | 10 |
| 2 | Ivabradine in the treatment of systolic heart failure- A systematic review and meta-analysis显示文摘AIM To perform a systematic-review and meta-analysis to compare outcomes of ivabradine combined with betablocker to beta-blocker alone in heart failure with reduced ejection fraction(HFr EF).METHODS We searched PubM ed, Cochrane, EMBASE, CINAHL and Web of Science for trials comparing ivabradine + betablocker to beta-blocker alone in HFr EF. We performed a systematic-review and meta-analysis of published literature. Primary end-point was combined end point of cardiac death and hospitalization for heart failure.RESULTS Six studies with 17671 patients were included. Mean follow-up was 8.7 ± 7.9 mo. Combined end-point of heart failure readmission and cardiovascular death was better in ivabradine + beta-blocker group compared to beta-blocker alone(RR: 0.93, 95%CI: 0.79-1.09, P = 0.354). Mean difference(MD) in heart rate was higher in the ivabradine + beta-blocker group(MD: 6.14, 95%CI: 3.80-8.48, P < 0.001). There was no difference in all cause mortality(RR: 0.98, 95%CI: 0.89-1.07, P = 0.609), cardiovascular mortality(RR: 0.99, 95%CI: 0.86-1.15, P = 0.908) or heart failure hospitalization(RR: 0.87, 95%CI: 0.68-1.11, P = 0.271). CONCLUSION From the available clinical trials, ivabradine + betablocker resulted in a significantly greater reduction in HRcoupled with improvement in combined end-point of heart failure readmission and cardiovascular death but with no improvement in all cause or cardiovascular mortality. Given the limited evidence, further randomized controlled trials are essential before widespread clinical application of ivabradine + beta-blocker is advocated for HFrEF. | Mahesh Anantha Narayanan Yogesh NV Reddy Janani Baskaran Abhishek Deshmukh David G Benditt Ganesh Raveendran | 2017 | World Journal of Cardiology2017，9，2： | 5 |

| 12 | Intra-islet endothelial cell and β-cell crosstalk: Implication for islet cell transplantation显示文摘The intra-islet microvasculature is a critical interface between the blood and islet endocrine cells governing a number of cellular and pathophysiological processes associated with the pancreatic tissue. A growing body of evidence indicates a strong functional and physical interdependency of β-cells with endothelial cells(ECs), the building blocks of islet microvasculature. Intra-islet ECs, actively regulate vascular permeability and appear to play a role in fine-tuning blood glucose sensing and regulation. These cells also tend to behave as 'guardians', controlling the expression and movement of a number of important immune mediators, thereby strongly contributing to the physiology of islets. This review will focus on the molecular signalling and crosstalk between the intra-islet ECs and β-cells and how their relationship can be a potential target for intervention strategies in islet pathology and islet transplantation. | Siddharth Narayanan Gopalakrishnan Loganathan Maheswaran Dhanasekaran William Tucker Ankit Patel Venugopal Subhashree SriPrakash Mokshagundam Michael G Hughes Stuart K Williams Appakalai N Balamurugan | 2017 | World Journal of Transplantation2017，7，2： | 1 |
