Publications from 2015-2019
Since the establishment of the national HPC facilities in 2014 and 2015, the number of scientific publications has only increased. This analysis was first published in DeiC's annual report for 2017, where a total of 290 publications were registered for the period 2015-2017. The list now counts 835 publications for the period 2015 to 2019, ie. a five-year period.
This overview draws a landscape of the scientific publications which have included computing power from one of the three national HPC plants respectively within Life Science (Computerome), multidisciplinary research (ABACUS2.0) and the social sciences and humanities (Cultural Heritage Cluster, KAC ).

Collection of publications
A total of 835 publications highlight the use of national HPC in Danish research in the period 2015 to 2019, and this picture cannot be drawn in the normal bibliographic way. Less than 20% of publications are "captured" by a bibliometric search (It is not written in the "Acknowledgment" or "Funding" field in the publication), and therefore the national HPC users have subsequently had to indicate specifically which computing power they have used.
In this analysis, each publication has been verified by HPC users, to get a true picture of how many publications have actually included national HPC.
New on the national list
The list now includes almost a doubling of publications from the social sciences and humanities, as the number has increased from 7 to 12 scientific articles in areas such as. economics, language and communication, analysis of the Danish world-wide web and 3D modeling within archeology. Searching for publications within 8 subject areas can now, as something new, easily be done online at:https://www.deic.dk/Supercomputere/HPC-publikationer.
For the first time, it is examined how many of the list's publications will contribute to the UN's global goals for sustainability in 2030. You can read more about this HERE.
In addition, the "Open Access" share of national DK-HPC publications is described HERE.

UN World Goals and publication list - NY
How do the national DK-HPC publications contribute to the UN's goals for sustainable development in the world? The Danish universities have begun to include the UN's 17 world goals in their strategy and visions. Most of the goals have the common denominator that technology will play a crucial role in solving the global challenges of the future, which include eradicating world poverty and hunger, helping our climate, reducing inequalities, ensuring good education and better health for all, sustainable economically growth, etc.
- A total of 353 publications (44%) were matched with an SDG (Sustainable Development Goal), of which the majority (339 publications) were categorized within SDG # 3: “Health and well-being” (Fig. 1).
- For SDG3, one can read that globally, one in four is affected at some point in life by mental illness and neurological disorders. More than 300 million people suffer from depression, almost as many have severe anxiety disorders and more than 800,000 people commit suicide each year [1]. These topics include has been elucidated through national DK-HPC, and in addition the 339 publications include studies of more than 50 different diseases, among others. using genome sequencing, epigenetic studies and disease progression analysis. You can explore the titles of the publications HERE (coming soon).
- The 353 publications that matched with an SDG goal were divided between 8 disciplines with emphasis on Life Science, which i.a. represents the health area (Fig. 2).
- Some publications were to be found within SDG2 (Stop hunger), SDG7 (Sustainable energy), SDG11 (Sustainable cities and communities), SDG13 (Climate efforts) and SDG15 (Life on land).
- It is noted that SDG6 (Clean Water and Sanitation) and SDG14 (Life at Sea) had no match in this analysis, although potential candidates were to be found among the 835 national DK-HPC publications.
- It is emphasized that the results presented here must be interpreted with caution, as an algorithm has not yet been developed that can perfectly assess and categorize the research publications as belonging to one or more of the world's objectives [2].
- This study uses a set of search criteria developed by Elsevier [3]

Open Access (OA) - NY
The publication of a scientific publication may be made available free of charge on the journal's website. This is an important parameter in relation to Open Science. Publications can be indexed as being "Gold", "Hybrid" or "Green" OA, which means that publications are respectively free, paid to be free or available for free access via parallel publishing (the latter is, for example, "Self-archiving" in the universities' archives and made available that way).
- A total of 60% of the DK-HPC articles are registered as Open Access (OA) in Scopus on average for the period 2015 to 2019. This is the sum of "Gold" and "Hybrid" OA.
- All 8 disciplines are represented in the OA part, where “front runners” are the Life Science areas Biology and Medicine (Fig 3A). All 8 disciplines also have publications that are not OA available (Fig. 3B).
- A lower% increase (Fig. 4, blue curve) is seen in the development in OA for the DK-HPC publications over the last 5 years based on “Gold” and “Hybrid” OA, while “The Danish Open Access Indicator”, where “Green” OA is also included when 78% for 2018 (Fig. 4, orange curve).
- The Danish Open Access Indicator contains publications that are respectively "Gold", "Hybrid" and "Green" OA, and thus includes a wider spectrum of OA publications than what we can discover in Scopus for the national DK-HPC analysis.
- For comparison, there were respectively 36%, 45% and 54% free access to the total Danish research publications from 2016, 2017 and 2018 via "The Danish Open Access Indicator" (Fig 4, DK-All-OA-DKI). These are lower values than for the publications with national DK-HPC.
- A total of 96% of the HPC publications were matched with the Danish Open Access Indicator.
- A total of 97% of the 835 publications were matched in Scopus.

Numbers and research areas
Here is information about research productivity (Number of publications) and which subject areas have found their way to national supercomputing in DK in the period 2015 to 2019.
- The total number of publications has almost tripled since the analysis was first conducted in 2017 (Fig. 5)
- Since the launch of the national HPC plants, 835 publications have been generated that included the use of national DK-HPC (Fig.6).
- Most HPC users are within the research areas Biology (Blue, 28%), Chemistry & Biochemistry (Orange, 15%) and Medicine (Yellow, 32%) (Fig. 7A).
- It is seen that the national HPC architecture has supported Life Sciences research via COMPUTEROME (Fig. 7B) and multidisciplinary research via ABACUS2.0 (Fig. 7C). The Cultural Heritage Cluster, KAC, was designed to support humanities and social sciences (Fig. 7D, Currently only two publications).
- A new national DK-HPC structure is being established in 2020.
- Different subject areas from the 8 Danish universities have used national HPC (Fig. 8). SDU has all 8 subject groups represented over the last 5 years, whereas DTU, KU and AU (and partly AAU) are mainly represented within the Life Science area (Blue, orange and yellow square). Few professional groups are represented from CBS, ITU and RUC respectively. The social sciences and humanities are represented from CBS, SDU and AU (Purple Square) respectively.
- A new national DK-HPC structure is being established in 2020.

If more than one of the Danish universities is represented by an author on one publication, it counts in several places.
Diversity and impact
Here is information on visibility and impact for the 835 publications that included national HPC in the period 2015 to 2019. This is illustrated by field-weighted citations for the publications as well as the share of publication in the top 10% most cited worldwide. Diversity refers to how widely research results are disseminated through different journals.
A description of FWCI and JIF can be found in the analysis from last year.
- A total of 40% of the publications are to be found in the top 10% most cited publications in the world for 2015 to 2019 (Fig. 9A), which is a high rate. This contributes to increasing the average for Denmark's total population of publications in the top 10% most cited worldwide, which in the same period was estimated at 22%.
- A total of 36% of the publications are visible in the top 10% of the most cited journals worldwide (Fig. 9B). This is higher than for Denmark's total population of publications (23%).
- The average FWCI is 3.74 for the 835 publications that included DK-HPC (Fig. 9D, blue bar), which is higher than the global average and higher than the total number of publications in DK and the OECD countries (Fig. 9D, gray and green bar respectively).
- The publication analysis for 2015-2019 shows higher field-weighted citation impact compared with total DK and OECD for 4 out of 6 subject areas (Fig. 9D, national HPC blue curve). So far, only 12 publications from the social sciences and humanities have been registered, which may explain the low FWCI for these areas.
- The 835 publications were available in 412 different international journals. This underscores the great diversity in the dissemination of research results, as the analysis from 2015 to 2018 identified 576 publications in 299 journals. This indicates that it is still a priority to disseminate its research internationally as widely as possible in new journals. Explore the 412 magazines HERE.
- A total of 17% of the publications are published in highly recognized time shifts with JIF values above 10 (Fig. 9C). At the same time, 40% of the publications can be found in the top 10 most cited publications in the world (Fig. 9A), which shows that many of the most cited publications can be located in time shifts without top ranking.
- Only 5% of the publications can be located in journals with the highest JIF ranking (Table 2). Thus, 12% of national HPC publications have a JIF between 10 and 25, with 17% having a JIF> 10 (See Fig. 9C).

Cooperation patterns
Here, information on collaboration patterns is identified in authorship from the publications resp. nationally (Collaboration across universities), internationally and with industry / sector research institutions. Collaboration can be seen as a way to develop new competencies - across universities and national borders.
- KU (n = 387 of the 835 publications), DTU (n = 266) and SDU (n = 292) had the authorship of the majority of the publications that included national HPC (Fig. 10). The proportion of publications that came exclusively from departments from one of the 8 universities is indicated in blue, while publications that included collaboration across Danish universities are indicated in orange.
- On average, in 68% of the publications, there was international collaboration spread over 110 countries via more than 3500 research units spread over more than 500 unique institutions (Fig. 11A).
- Industry was represented in 13% of the publications that included national HPC, and sectoral research was represented in 27% of the publications (Fig. 12A). A total of 332 publications, corresponding to the 40% that includedsamarbejde med industri eller sektorforkning, akkumulerede over en fire-årig periode (Fig. 12B).
- Almost every third publication (27%) included collaboration with hospitals from the Danish regions (Fig. 13).
- The Capital Region of Denmark and Southern Denmark were represented in most of the publications (Figs. 13 and 14), and a marked increase in the use of national HPC via the hospitals was identifiable from 2017 to 2018 (Fig. 14).

"Hot topics" from DK-HPC
How prominent and visited a topic is in the sciences ("Topic prominence") can be calculated from the number of citations, citescore and "views" in Scopus. The higher the prominence percentile, the more it is an area that is very much focused on (Top10% ranges from 0.9-0.99 percentile). Popularly speaking, one could say that a topic with a high prominence percentile with high probability is a "hot topic" within a specific science. This does not mean that research with low prominence is not important, there is just not as much focus on the area measured via the above parameters.
- Below is a more detailed overview of scientific disciplines that have used DeiC national HPC from 2015 to 2019 (Fig. 15). It is seen that the subjects of the publications are mainly attributed to life science and natural science (Red circles) as well as computer science and physics (Blue and purple circles), but also social scienes are represented (Yellow circles, Fig. 15).
- Description of "Topic prominence Clusters" for the total of 835 publications can be found in Table 2.
