Hot take: optics are better abstraction than lenses, in *all* use cases. Why? They make explicit all the things you're implicitly thinking about anyway when using lenses. I think they are really important in shaping how we think about bidirectional maps. A short thread. 👇 1/9

Want to include the menstrual cycle in your scientific work, but aren't sure how to do it? My lab (@katjaschmalen) have just published an article on best practices for observational studies of the cycle! Thread below! 🧵

Despite decades of research on the menstrual cycle, empirical studies have not adopted consistent methods for operationalizing the menstrual cycle, resulting in confusion in the literature and limited possibilities to conduct systematic reviews and meta-analyses.

Below, I summarize this "how to" article, and relay some of the key points!

PARTICIPANTS: All participants should be naturally-cycling people with ovaries (remember that they are not necessarily "women"! 🏳️‍⚧️ ⚧).

We provide a Reproductive Status Questionnaire with rules for identifying naturally-cycling people (current function of the sexual organs and hormonal/other medications that stop the cycle).

HELLO: If you pee and every time you finish, your urine looks like this picture, you may have a serious medical illness.

Foamy urine especially if it is persistent and noticeable over time may mean you have a serious kidney problem.

Let’s talk about this today...
RT for others.

What are the features of a normal urine?

A normal urine should have a light yellow colour, painless, odourless (or faint smell), steady stream and should ideally not foam when you pee.

When there’s something wrong, then you see changes in all the above normal features of urine.

For instance if urine becomes very deep yellow, it may mean you are dehydrated;

If urine becomes painful or smells really really bad, it may mean you have an infection;

If urine has a poor stream, especially in a man, it may mean a prostate problem like cancer.

Do you get me?

So today let’s talk about Foamy Urine.

What are the things that can cause urine to suddenly be foamy. As I said in the first tweet, it MAY mean a serious medical illness like a serious kidney problem.

First things first- it does NOT always mean a problem but it may as well.

Now what are the causes of Foamy Urine:

1. SPEED-
If you pee really fast or with a lot of force, it may make your urine more foamy than usual. The speed and force makes the urine generate a lot of bubbles which tend to almost quickly disappear as it is formed in the toilet bowl.

• With expanding capacities at 2.6Million Tones and utlization of 75%, scalability has been affected.
• While the prices of steel has gone by by around 35%, due to shortage of steel.

• Apl Apollo being the dominant player past connection with steel companies worked well.

THIS IS A CATCHY & ATTENTION-GRABBING TITLE

Today, the Province will likely announce what zone of the reopening framework we'll shift into as of Tuesday. Whatever is announced, though, doesn't change what we need to do. Why?

Kindly read these 14 tweets & we'll tell you. (1/14)

Fun fact: COVID-19 does not follow us on Twitter. COVID doesn't know, or particularly care, if we're in the Red or Orange zone.

The behaviours of the virus do not depend on the current ‘zone’ of public health restrictions. And, to be perfectly candid, neither should ours. (2/14)

Once upon a time we used to say #WeAreInThisTogether in our messaging. Here's the thing: we are, but we aren't. Not everyone is experiencing this pandemic the same.

Nurses, doctors, paramedics & healthcare workers have experienced things much differently than most of us. (3/14)

Some people have been home & isolated for months, while others haven't been able to stop working.

Business owners & hospitality workers have been on a rollercoaster of openings & closures.

Students, parents, teachers & school staff have had to adapt to going from online (4/14)

to in-person learning (and back again) numerous times.
And this virus has disproportionately affected some groups more than others.

But there's the thing: while our experiences of this pandemic haven't been shared, we do have a shared goal.

And we can reach it together. (5/14)
