This is the most documented genocide in our history, no one can claim ignorance, no one can say they didn’t know…🇵🇸💔

List of high-level Alzheimer's researchers accused of credible fraud:🧵 #1 - Marc Tessier-Lavigne Genentech pointed out problems in his 2009 Nature paper in 2012. After an expose by @tab_delete, he had to resign from Stanford Presidency, but can still run lab and do research.

Is it me or the train moving? 🚂🫨 📢New preprint📢 on multi sensory integration of conflicting sensory inputs in human balance: doi.org/10.1101/2024.08.30.6… Moving the visual scene creates a conflict and visual orientation cues become erroneous. How does the CNS resolve this?

The evidence: 1) The model explains and predicts a lot of data 2) The nonlinear element distorts body sway: the model predicted sway evoked at frequencies that are not contained in the stimulus

Conclusion: sensory integration can be characterized by two variables. 1) How much do we use a sensory system (in %); 2) At which velocity do we start to suppress a moving reference.

I am often invited to review papers on deep learning for medical images. Unfortunately many papers do the same mistake; they split data into training/validation/test on the slice/image/patch level instead of on the patient level. This will lead to inflated test scores, as images from the same patient then can appear in both training and test sets. Since these images can be very similar, the network will perform extremely well on the test images. If you use 2D networks on 3D data, the 2D slices have to be split on the patient level, not on slice level. If you use 2D networks on a dataset where each patient has several 2D images, the images have to be split on the patient level, not on image level. If you use deep learning for digital pathology, the patches have to be split on the patient level, not on patch level. nature.com/articles/s41598-0… link.springer.com/chapter/10… nature.com/articles/s41597-0…

The key idea is simple: vision improves balance. But what if you turn around in front of a white wall? The image on the retina will not change and you lose visual orientation. Our device displays space orientation cues in the periphery to avoid such situations.

In this study we use a very crude and simple version to test the idea. We show that we can reduce spontaneous sway, thus improve balance. Can we prevent falls? We don't know, but we are working hard to find out. Thank you @biosmanager & @StephanStreuber for the joint effort!

15/ All of the above has been made possible through the strong support of most mainstream media in Israel as well as the West, primarily in the United States, the United Kingdom and Germany.

1/ I’m an Israeli historian. My community is still too silent about the horrible war in Gaza. Over 8 months I’ve closely followed the war, reading >1000 articles and viewing >1000 videos/images of the war from all sides. My summary conclusions & full report are in the 🧵:
