Intracerebral Hemorrhage (ICH): Understanding the CT imaging featuresPetteriTeikariPhD
Overview of CT basics and deep learning literature mostly focused on the analysis of ICH.
Intracerebral hemorrhage (ICH), also known as cerebral bleed, is a type of intracranial bleed that occurs within the brain tissue or ventricles. Intracerebral bleeds are the second most common cause of stroke, accounting for 10% of hospital admissions for stroke.
For spontaneous ICH seen on CT scan, the death rate (mortality) is 34–50% by 30 days after the insult,and half of the deaths occur in the first 2 days. Even though the majority of deaths occurs in the first days after ICH, survivors have a long term excess mortality of 27% compared to the general population.
Deep learning and computational steps roughly can be categorized to 1) Preprocessing, 2) Image Restoration (denoising, deblurring, inpainting, reconstruction), 3) Diffeomorphic registration for spatial normalization, 4) Hand-crafted radiomics and texture analysis, 5) Hemorrhage segmentation, among other relevant head CT issues

Soon gi Park (LetinAR): PinMR: Novel Optical Solution for AR Glasses
LetinAR is a Seoul-based startup developing see-through optical systems for wearable augmented reality devices. Based on our unique pin mirror technology which has quite different approaches from any other existing combiner optics, LetinAR has demonstrated ultrawide field-of-view more than 80 degrees with 8K high resolution. LetinAR also presented a form-factor-oriented glasses prototype device having the same appearance of normal glasses. In this presentation, we introduce a pin mirror technology and its benefits and contributions to wearable AR hardware including high image quality without any degradation, visual comfort supporting correct vergence and accommodation, wide field-of-view providing immersive experience as well as cost effective manufacturing process. We believe that the advantages of the pin mirror technology will not only suffice the optical requirements in future AR devices, but also shorten the beginning of AR/VR/MR era.

Outlining the common challenges encountered when structuring clinical and research datasets for deep learning training.
Typically the datasets are so unstructured that they are impossible to analyze by any deep learning practitioners. And the cleaning and data wrangling ends up taking most of the time which could have been planned properly even before the clinical data acquisition.
One could argue that especially for medical data, the annotated data is the new gold, and not just the Big Data scattered all over the place. This is practice translates to efforts to design as intelligent as possible data labelling pipelines for efficient use of expert clinician annotation work.

All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Lightwear
“Lightwear” consists of a series of garment- and accessory-based light-emitting wearables designed to
administer light therapy for on-the-go treatment of Seasonal Affective Disorder (SAD). To date, there
have been few successful products developed for wearability and portability to ease the uncomfortable
nature of traditional light box treatment. Lightwear explores the integration of light into 3D printed and
textile substrates to create fashion-forward wearables to address issues related to BLT efficacy, usability,
adoption, and convenience.
This research was presented at TEI 2015 and received Best Paper at PervasiveHealth 2016. This
work was developed at Microsoft Research by Halley Profita (CS PhD at CU Boulder), Asta Roseway, and

The global eyewear market is a $180billion market dominated by one company

we could see this as a deal to industrialize 3D printing for many products. But, given
Materialise’s lead in eyewear, is this perhaps the entire play for BASF? Maybe a chemical

Conclusion
A compact design of see-through NED, featuring a pair of
corrective lenses coated with multiplexed volume holograms,
has been proposed. Based on the simulation, its optical
performance including DE, FOV, MTF, and distortion has been
studied. By eliminating the need for extra glasses or contact
lens, this type of see-through NED could be particularly
appealing to the users who are more or less visually impaired.
In addition to myopia, our future work will extend to
hyperopia, presbyopia, astigmatism, and combinations of
different refractive anomalies.
