It was great to talk about reproducible workflows for @riotscienceclub @riotscience_wlv. You can watch the recording below, but if you don't want to listen to me talk for 40 minutes, I thought I would summarise my talk in a thread:

 My inspiration was making open science accessible. I wanted to outline the mistakes I've made along the way so people would feel empowered to give it a go. Increased accountability is seen as a barrier to adopting open science practices as an ECR https://t.co/bNK6poNpzx
It also comes across as all or nothing. You are either fully open science or your research won't get anywhere. However, that can be quite intimidating, so I wanted to emphasise this incremental approach to adapting your workflow https://t.co/HS3dx5qJL3
There are two sides to why you should work towards reproducibility. The first is communal. It's going to help the field if you or someone else can reproduce your whole pipeline.
There is also the selfish element of it's just going to help you do your work. If you can't remember what your work means after a lunch break, you're not going to remember months or years down the line https://t.co/iRSXISI5NE
Pre-registration is super helpful, but it takes time to learn how to do it effectively. I had no support for my first attempt and it was awful. https://t.co/o0QgrtBFfJ
But I learnt from my mistakes and eventually got to a point where I'm happy with my approach.
Some aspects of open science can't be added at the end. If you want to share your data, it has to be planned from the ethics stage and your participants have to consent to it. Just remember not all data can be shared openly for ethical reasons.
Sharing materials is one of the easiest things you can do, but very few researchers do it. You can share your stimuli (providing there's no copyright issues) and your task scripts. If you use @GorillaPsyc, there is an open materials function making it super easy.
Double check your analysis pipeline, especially when the results support your hypotheses. I caught an error in my first PhD study before it was too late, but it could have been super embarrassing.
You don't have to go the full R Markdown manuscript route, but I recommend at least scripting any data processing. If you do make a mistake, at least that error is reproducible. You can also use intermediaries like @tidystats to embed results from R into your Word file.
Finally, if you can't read the article in the first place, you can't reproduce it. Most journals allow you to post pre/post-prints and you can upload your dissertation/thesis to Thesis commons. Just double check it's permitted by your target journal: https://t.co/iIIw1VDHdC
Hopefully, this seminar shows people fuck up from time to time. It's about learning from those mistakes and doing what you can to minimise them in future. Try making your workflow more reproducible one step at a time. It'll be worth it in the long-run for you and the community.

@mugecevik is an excellent scientist and a responsible professional. She likely read the paper more carefully than most. She grasped some of its strengths and weaknesses that are not apparent from a cursory glance. Below, I will mention a few points some may have missed.
1/


The paper does NOT evaluate the effect of school closures. Instead it conflates all ‘educational settings' into a single category, which includes universities.
2/

The paper primarily evaluates data from March and April 2020. The article is not particularly clear about this limitation, but the information can be found in the hefty supplementary material.
3/


The authors applied four different regression methods (some fancier than others) to the same data. The outcomes of the different regression models are correlated (enough to reach statistical significance), but they vary a lot. (heat map on the right below).
4/


The effect of individual interventions is extremely difficult to disentangle as the authors stress themselves. There is a very large number of interventions considered and the model was run on 49 countries and 26 US States (and not >200 countries).

Did you know that all the nuclear bombs we exploded in the '40s-50s-60s have permanently contaminated all the steel the world has produced since then? All steel in the world is divided into two categories: pre-1945 non-contaminated steel, and post-1945 contaminated steel.

How?

Nuclear bombs (including the tests) create a lot of radioisotopes that are not found in nature. For example Cobalt-60 (a radioactive version of Cobalt-59). And since the 1945 Trinity test, these have all dispersed in the atmosphere.

What does this have to do with steel?

The process of manufacturing steel uses atmospheric air (or atmospheric oxygen). Some of the radioisotopes like Cobalt-60 get pulled in too, and as a result, any steel produced after 1945 has embedded in it some of these radioisotopes, sitting there emitting gamma rays.

Why do we care about traces of radioisotopes in steel? When making Geiger counters, or medical devices to check for radioactive contamination, or astronomical instruments, the emissions from the contaminated steel would interfere with the measurements.

So we need pre-1945 steel

Pre-1945 non-contaminated steel is called "low background steel". And when we need it, where do we get it from?

We go, find pre-World-War-II sunken shipwrecks, and then salvage the steel (and lead) from those to build our instruments which need heavy radiation shielding.

The distinction of measuring the time in a scientific manner is achieved only by Bhāratīyas. Time has been measured from the smallest dimension to infiniteness. Even Time is envisioned as God and venerated. Paramēśvara was extolled as ‘Mahākāla’, the very embodiment of Time.


Nārāyaṇa Upaniṣad envisages Nārāyaṇa as ‘Kālaśca Nārāyaṇa:’, the very embodiment of Time, ages ago. The measurement of Time by Bhāratīyas is as ancient as the very God Himself. Count of many future ages has also been done even from very ancient times.

Since these calculations aren't dependent upon the birth & death of any individual, but are done based on astronomical science, they are thoroughly scientific. Unfortunately, during the British rule, the Bhāratīya way of Time measurement was casted as an illusion...

...with an evil intention to establish their command. Though it is 70+ years since independence, blindly time is still measured as BC & AD or CE in this religion-less land without even making any attempt to comprehend the magnanimity of Bhāratīya Time measurement methods.

AGI Significance Paradox: As progress accelerates towards AGI, the number of people who realize the significance of each new breakthrough decreases.

Why is it that you can boil a frog in water without it jumping out if you gradually increase the temperature?

The problem for the frog is that it does not have the internal models to realize that there is a change in the water temperature. A cold-blooded creature like the frog has its temperature regulated by the external environment.

To recognize change, an agent must have an internal model of reality that is able to recognize this change. Unfortunately, a majority of the population do not have good models of human general intelligence.

In fact, even the simplistic dual-process model of system 1 and system 2 is not very well known.

Today, we are bringing other exciting results involving black holes and AI. We released a new paper:

"Black Hole Weather Forecasting with Deep Learning: A Pilot Study"

Work by Roberta Duarte (@import_robs), Rodrigo Nemmen (@nemmen) and João Paulo Navarro (from @NVIDIABrasil).

The authors used deep learning to simulate the dynamics of gas accreting onto a black hole, i.e., black hole weather forecasting.

They trained the model (U-Net) with frames from numerical solutions of the hydrodynamical equations.

Numerical simulations are time-consuming. A simple simulation can take as long as 7 days to finish. If we go with more complex simulations, this time may increase.

We want to investigate if deep learning can be a new method to simulate accurately in less time!


In the paper, they discussed two examples:

1- The model simulating only one system after learning only from this system
2- The model simulating an unseen system after training with several systems with different initial conditions

In the first example, they trained the model with a single system and analyzed how the model simulates by iterative predictions.

The result is that the model can simulate up to 8e4 gravitational time accurately with a speed-up of 30000x faster!

fascinated by this man, mario cortellucci, and his outsized influence on ontario and GTA politics. cortellucci, who lives in vaughan and ran as a far-right candidate for the italian senate back in 2018 - is a major ford donor...


his name might sound familiar because the new cortellucci vaughan hospital at mackenzie health, the one doug ford has been touting lately as a covid-centric facility, is named after him and his family

but his name also pops up in a LOT of other ford projects. for instance - he controls the long term lease on big parts of toronto's portlands... where doug ford once proposed building an nfl stadium and monorail... https://t.co/weOMJ51bVF


cortellucci, who is a developer, also owns a large chunk of the greenbelt. doug ford's desire to develop the greenbelt has been

and late last year he rolled back the mandate of conservation authorities there, prompting the resignations of several members of the greenbelt advisory

How to trade on Expiry day with Nifty straddle?
(System trading on Expiry)

Triple straddle is one of the best and accurate methods for expiry day

If nifty trading at 15720 then will sell three straddles above 50 points from ATM, below 50 points and ATM.

Ex.
Sell straddle 15700(ATM), 15650(ATM-50), 15750 (ATM+50)

Stoploss of 80% on every leg and run your trade till 3 PM

Once SL hit in any Leg just keep holding other leg till expiry with SL (Never or less chance to hit both SL on expiry day)

Trading timing at 9:20 the Morning

Trading view scanner process -

1 - open trading view in your browser and select stock scanner in left corner down side .

2 - touch the percentage% gain change ( and u can see higest gainer of today)


3. Then, start with 6% gainer to 20% gainer and look charts of everyone in daily Timeframe . (For fno selection u can choose 1% to 4% )

4. Then manually select the stocks which are going to give all time high BO or 52 high BO or already given.

5. U can also select those stocks which are going to give range breakout or already given range BO

6 . If in 15 min chart📊 any stock sustaing near BO zone or after BO then select it on your watchlist

7 . Now next day if any stock show momentum u can take trade in it with RM

This looks very easy & simple but,

U will amazed to see it's result if you follow proper risk management.

I did 4x my capital by trading in only momentum stocks.

I will keep sharing such learning thread 🧵 for you 🙏💞🙏

Keep learning / keep sharing 🙏
