Abstract:
We present a new, fully generative model for constructing astronomical catalogs from optical telescope image sets. Each pixel intensity is treated as a random variable with parameters that depend on the latent properties of stars and galaxies. These latent properties are themselves modeled as random. We compare two procedures for posterior inference. One procedure is based on Markov chain Monte Carlo (MCMC) while the other is based on variational inference (VI). The MCMC procedure excels at quantifying uncertainty, while the VI procedure is 1000 times faster. On a supercomputer, the VI procedure efficiently uses 665,000 CPU cores to construct an astronomical catalog from 50 terabytes of images in 14.6 minutes, demonstrating the scaling characteristics necessary to construct catalogs for upcoming astronomical surveys.

Abstract:
With the advance of imaging technology, digital pathology imaging of tumor tissue slides is becoming a routine clinical procedure for cancer diagnosis. This process produces massive imaging data that capture histological details in high resolution. Recent developments in deep-learning methods have enabled us to identify and classify individual cells from digital pathology images at large scale. Reliable statistical approaches to model the spatial pattern of cells can provide new insight into tumor progression and shed light on the biological mechanisms of cancer. We consider the problem of modeling spatial correlations among three commonly seen cells observed in tumor pathology images. A novel geostatistical marking model with interpretable underlying parameters is proposed in a Bayesian framework. We use auxiliary variable MCMC algorithms to sample from the posterior distribution with an intractable normalizing constant. We demonstrate how this model-based analysis can lead to sharper inferences than ordinary exploratory analyses, by means of application to three benchmark datasets and a case study on the pathology images of $188$ lung cancer patients. The case study shows that the spatial correlation between tumor and stromal cells predicts patient prognosis. This statistical methodology not only presents a new model for characterizing spatial correlations in a multitype spatial point pattern conditioning on the locations of the points, but also provides a new perspective for understanding the role of cell–cell interactions in cancer progression.

Two years ago the photographer Palani Mohan received life-saving heart surgery. After his recovery he started to see the world and his work differently. He was drawn to images, old and new, that evoked silence and peace, and inspired reflection. ‘As we spend these days and weeks at home, I’m grateful for this time I have with my thoughts, and to witness the power of the small good things that surround us,’ he says. ‘My hope, especially in these difficult times, is that when you look at these images you can find a place for yourself within them, and be still.’

The internet is a scary enough place as it is, and now with the added misinformation and panic surrounding the coronavirus pandemic, it's even scarier. Thanks to the United Nations and dozens of artists, however, the internet just got a little more beautiful. 

In late March, the UN put a call out to artists to help combat the spread of COVID-19. They sought creatives to create content around six areas of WHO and UN priority actions: personal hygiene, social distancing, knowing the symptoms, spreading kindness, myth-busting, and doing more/donating. Tens of thousands of artists answered the call in two weeks, and now the COVID-19 Response Creative Content Hub is available for browsing.  Read more...
