When to worry about negative weights in MVA training for HEP analysis

A discussion at DS@LHC2015 concerned the treatment of negative weights in MVA training. This is relevant for HEP since the advent of MC generators at NLO in QCD, as [the matching of Matrix-Element to Parton-Shower... continue reading

Awards specifically to free educational software that has proven to be effective in randomized field experiments involving a large number of schools.

Ben Goldacre described randomized field experiments as following: ""Randomised trials are our best way to find out if something works: by randomly assigning participants to one intervention or another, and measuring the outcome we're interested... continue reading

Data Science and High Energy Physics collaboration enforcement by Higher Education Institutions

Data Science @ LHC workshops have been intensifying cooperation in the Data Science (DS) and High Energy Physics (HEP) professional communities. The need for such cooperation risen substantially in recent years, since it requires combining... continue reading

Brief Ideas for the Data Science at LHC Workshop 2015

The Data Science @ LHC workshop was a resounding success. We do not plan to have traditional proceedings tied to individual talks, but we do want to capture the ideas that were generated during the workshop. With that in mind, we want to try... continue reading

Hyperglycaemia: both cause and effect of diabetes

Current thinking suggests diabetes has variable causes, is inevitably progressive, and causes hyperglycaemia. Type 1 is an autoimmune disease causing β-cell (source of insulin) death, and type 2 is an insulin activity deficiency (insulin... continue reading

Assessing 'ownership' of useful evidence for measuring impact and giving credit

An evidence synthesis, such as a systematic review, guideline or other evidence summary, will include collated and filtered data, typically from published reports of primary studies. Those studies were instigated, carried out, supported and to... continue reading

Rabies Virus: Toward Ante-Mortem, Sub-Clinical Diagnosis by Electron Microscopy

According to the Centers for Disease Control and Prevention (CDC), Rabies is the cause of approximately 59,000 deaths annually worldwide. Rabies is 100% fatal and with no approved treatment or survivability upon clinical symptom presentation. With... continue reading

Use Real-time MRI to Track Nitric Oxide in Our Brain

We have already known that nitric oxide plays a important part in long-term potentiation as a neurotransmission in our brain, especially in hippocampus, and consequently plays an important role in both short-term memory and long-term memory. Thank... continue reading

From Budapest via San Francisco to The Hague: a bird's eye view of two dozen scholarly communication charters.

Idea: speeding up the transition towards a scholarly commons by summarizing and reviewing existing charters and pinpointing where there’s still work to be done.

Science is in transition. But in what direction, demanded by whom, accepted by whom... continue reading

Teen-Driven Open Science

Through the Hive Mapping Cooperative, five youth-serving organizations in Chicago have been working to develop shared systems for teens to collect, analyze, visualize, and share georeferenced data using free and open... continue reading
