The JKO scheme is a time-discrete scheme of implicit Euler type that allows to construct weak solutions of evolution PDEs which have a Wasserstein gradient structure. The purpose of this work is to study the effect of replacing the classical quadratic optimal transport problem by the Schr\"odinger problem (\emph{a.k.a.}\ the entropic regularization of optimal transport, efficiently computed by the Sinkhorn algorithm) at each step of this scheme. We find that if $\epsilon$ is the regularization parameter of the Schr\"odinger problem, and $\tau$ is the time step parameter, considering the limit $\tau,\epsilon \to 0$ with $\frac{\epsilon}{\tau} \to \alpha \in \mathbb{R}_+$ results in adding the term $\frac{\alpha}{2} \Delta \rho$ on the right-hand side of the limiting PDE. In the case $\alpha = 0$ we improve a previous result by Carlier, Duval, Peyr{\'e} and Schmitzer (2017).

We are interested in the Caffarelli-Kohn-Nirenberg inequality (CKN in short), introduced by these authors in 1984. We explain why the CKN inequality can be viewed as a Sobolev inequality on a weighted Riemannian manifold. More precisely, we prove that the CKN inequality can be interpreted in this way on three different and equivalent models, obtained as weighted versions of the standard Euclidean space, round sphere and hyperbolic space. This result can be viewed as an extension of conformal invariance to the weighted setting. Since the spherical CKN model we introduce has finite measure, the $\Gamma$-calculus introduced by Bakry and Emery provides an easy way to prove the Sobolev inequalities. This method allows us to recover the optimality of the region of parameters describing symmetry-breaking of minimizers of the CKN inequality, introduced by Felli and Schneider and proved by Dolbeault, Esteban and Loss in 2016. Finally, we develop the notion of n-conformal invariants, exhibiting a way to extend the notion of scalar curvature to weighted manifolds such as the CKN models.

Keyword selection is the second Sudan Journal of Medical Sciences (SJMS) short guidance piece on the international academic standards. As a Section Editor at SJMS, I am honored to be invited to write in this series. In future, I can see SJMS leading the way to improving the publishing standards in Sudan's medical field. And with the current practice and unique services that SJMS provides for their readers and authors, it marks its step to be one of the best regional journals in the discipline. The Importance of Keywords As authors, we aspire to share our work among the readers in our field and get appropriately cited. Here comes the volume for the authors' keywords. The first journey for each manuscript begins with a literature review in which the indexing databases such as Scopus and PubMed are searched for any present work related to our ideas. This ends by the citation of most of those works in our reference list. It is curial to select your keywords so that it acts as a promoter for your work among your colleagues. Apart from being used by the indexing service to classify your work, keywords for the publisher and the editorial board serve as a guidance for choosing the referee for your article and your paper's subject. How to choose your keyword? First, make a list of words from the manuscript, which you believe represents the work's essential idea. They could also be a phrase (e.g., colon cancer). Most researchers use sentences or phrases in search engines. Do not use words from your title, as this will decrease the chances of the article appearing during the logarithmic search. There is also a word generator engine like MeSH on Demand, a google keyword planner. Each journal has its own maximum number of keywords; for SJMS, the number of keywords are specified according to the article types. Next, have a look at the standard term used for indexing in the medical field (MeSH, PsycInfo, and others) and ensure that the keyword of your choice is listed there. Lastly, go through the standard search engine used commonly by professionals in your field and type it to see if the same titles as yours come up. To publish means to be known. I believe each article's minor part deserves the same input as a significant section.

Several airborne magnetic surveys were conducted for iron ore exploration over the Mesabi Iron Range over the past 10 years. One of the surveys, flown in 2007, was used for mine planning on the eastern extension of the Hibbing Taconite Mine near Hibbing, Minnesota. This area was subsequently mined and nearly all the taconite ore was extracted. In early 2018, while conducting an additional survey for Cleveland-Cliffs in the Mesabi Iron District, we had the unique opportunity to acquire new data over the mine workings and compare the pre and-post-mining geophysical signatures. This study will compare the before and after magnetic signatures and create a 4-D analysis of the change in magnetic signal attributed to a known amount of ore extraction. We will discuss the methodology used to compare the time-lapse dataset and those acquisition factors that were normalized in order to isolate the changes in magnetic signal due to mining activity. We will also discuss the ability to correlate the time-lapse survey with the shape, volume, and grade of the extracted ore and the possible application of these estimates to resources within unmined areas in similar terranes Presentation Date: Tuesday, September 17, 2019 Session Start Time: 8:30 AM Presentation Time: 8:30 AM Location: 214D Presentation Type: Oral

There are numerous examples of people with cancer using social media to seek support, raise awareness and even raise funds for research. The first one that comes to mind is 19-yearold Stephen Sutton from Birmingham who charted his journey of bowel cancer on his website, Facebook group, Twitter, Instagram and YouTube, raising more than £3.5 million for teenage cancer research and winning over more than 1 million strangers before passing away last week. Of course, we are losing young people to cancer every day, but by sharing his story Stephen touched people, connected people, and opened up the dialogue around living with cancer. He also had the courage to go that step further in sharing what it was like on bad days, how he felt when he thought he was facing death, and saying goodbye online in his last days. There are many websites, forums and Facebook groups, usually started by cancer survivors or their family members, that exist to provide support to patients with cancer. The Facebook Sucks group, CancerConnect TwistOutCancer and StupidCancer are just a few examples. There have also been several Social media and the changing face of cancer

The number of medical practitioners in the developed world has increased but in relative terms their incomes have decreased. Published comments suggest that some doctors are dissatisfied with what they earn. However doctors are still perceived as having a high status in society. Publicly available data suggests that doctors chose to live and work in affluent suburbs where arguably the need for their skills is less than that in neighbouring deprived areas. The gender balance in medicine is also changing with more women entering the workforce and a greater acceptance of parttime working arrangements. In some countries doctors have relinquished the responsibility for emergency out of hours care in general practice and personal continuity of care is no longer on offer. The profession is also challenged by policy makers' enthusiasm for guidelines while the focus on multidisciplinary teamwork makes it more likely that patients will routinely be able to consult professionals other than medical practitioners. At the same time the internet has changed patient expectations so that health care providers will be expected to deploy information technology to satisfy patients. Medicine still has a great deal to offer. Information may be readily available on the internet, but it is not an independently sufficient, prerequisite for people to contend with the physical and psychological distress associated with disease and disability. We need to understand and promote the crucial role doctors play in society at a time of tremendous change in the attitudes to, and within, the profession.

Over the decades fictional doctors have been portrayed in very different ways. Some have been father figures whilst others have been deeply flawed. The presentations reflect a very different view of the medical profession and this is especially evident in television dramas over the decades. At the same time news channels have reported some doctors saving lives and others committing crime. In this editorial I review the portrayal of doctors on screen from the 1960s to the present day. Often these reports or stories have reinforced trust in the medical profession. However occasionally they have led to calls for closer regulation. To place the issue in context I first review the published view of the ‘ideal’ doctor.

Medical schools are charged with preparing their students for lifelong service of humanity. However, as discussed in this editorial many medical students may not be served well by the experience of their training. It is paramount that what is taught at medical school and those who teach prepare an educated but resilient workforce. The unmet expectations of medical students and their experience as newly qualified doctors sometimes reinforce the damage done during medical training.

Since 1990s, the European institutions have been discussing on the importance to establish a HealthIndicators Monitoring System. This system would: undertake a “critical review of existing health data and indicators; develop appropriate methods for the collection of the progressively comparable health data needed to establish these indicators; develop a reliable system for the transfer and sharing of health data and indicators, essentially by means of the telematic interchange of data; identify methods and tools required for conducting analyses and producing reports on state of health, trends and determinants, and the impact of health-related policies” (according to the speech made by the European Commission representative, Mr. Frédéric Sicard, during the former EUPHA Conference held in Rome, last November).These are the outcomes of the Health statistics — Key data on health 2002, issued on March 8th 2004 and prepared by the Office for National Statistics (ONS), United Kingdom, and the sector ‘Health and safety’, of Unit E.3 (Education, health and culture) of Eurostat, on behalf of the European Commission.
