If you shine light of high enough energy on to a metal, electrons will be emitted from the metal.

During a normal pregnancy, oxidative stress enhances antioxidant mechanisms that are capable of reacting by way of enzyme activity and non-enzyme free radical deactivators. However, pregnancy is also a state in which this adaptation and balance may be easily disrupted.

There is strong evidence that a chronicin flammatory reaction combined with the presence of a local oxidizing environment may play a vital role in the etiology and development of complications during pregnancy.

In late pregnancy, damage to DNA (especially when it is caused by oxidative stress) is associated with pre-eclampsia(PE), intrauterine growth restriction (IUGR), and the death of mothers in developing countries; it largely determines pregnancy – related susceptibility to diseases

The referential values of ROS and NOS and their minimal and safe concentrations or physiologically beneficial concentrations are yet to be determined.

The measurement of oxidative stress in vivo is perceived as controversial,

as the sen-sitivity and specificity of various oxidative stress markers is unknown.. .

This nonspecific cation channel opens when illuminated with blue light, depolarizing the cell [4, 6] to trigger action potentials cells with high temporal precision [5]. Since the initial discovery of ChR2, many modifications have been made to refine the kinetic properties.

For example, ChETA, engineered to address limitations of spike fidelity with ChR2, has faster temporal kinetics and can maintain reliable spike precision up to 200 Hz [7].

Halorhodopsins (NpHR), light-gated chloride pumps activated by yellow light, allow for temporally specific hyperpolarization with single spike precision [8–10].

Archaerhodopsin-3 (Arch), a yellow light-activated outward proton pump, is an increasingly popular tool for light-induced hyperpolarization to inhibit cellular activity. Arch recovers spontaneously from inactivation with a much shorter recovery time than NpHRs [11].

Arch currents continue to increase with increasing light intensity, while NpHRs saturate [11]. The increased light sensitivity of the ArchT variant, along with better membrane targeting, allows for improved neural silencing both at cell bodies and terminals [12].

I recently submitted my PhD dissertation titled "Illiberalism Beyond Borders. Dissecting Russian and Turkish External Influence in Bosnia and Georgia" at @FU_Berlin. Interested in what I found? Read this thread ⬇️

To begin with, I hypothesise that illiberal external influence (IEX) is more likely to contribute to the contestation of #democracy in a given polity when it appears in the context of a favorable domestic environment and the absence of liberal external counterpressure.

I particularly scrutinise the role of domestic elites in facilitating/obstructing IEX, based on findings by J. Tolstrup, @otansey, R. Vanderhill et al. I also look at how liberal ext. counterpressure can help prevent a major contribution of IEX to the contestation of #democracy.

Between 2016-2018, I conducted 95 interviews in #Tbilisi, #Moscow, #Sarajevo & #BanjaLuka (thx to all interlocutors!). Given the increasingly unfree environment in Turkey, I didn't dare to make a trip to Ankara, but talked to local experts about Turkish IEX in BiH & Georgia.

In #Bosnia, #Ankara has engaged in illiberal sponsorship of the Party of Democratic Action for many years. However, in both Bosnia and #Georgia, Ankara mostly exerted illiberal external influence after the 2016 coup attempt, following which it exerted pressure on the rule of law.

In this thread, I'll help you understand the basics of Binomial Thinking.

The future is always uncertain. There are many different ways it can unfold -- some more likely than others. Binomial thinking helps us embrace this view.

The S&P 500 index is at ~3768 today.

Suppose we want to predict where it will be 10 years from now.

Historically, we know that this index has returned ~10% per year.

If we simply extrapolate this, we get an estimate of ~9773 for the index 10 years from now:

3/

What we just did is called a "point estimate" -- a prediction about the future that's a single number (9773).

But of course, we know the future is uncertain. It's impossible to predict it so precisely.

So, there's a sense of *false precision* in point estimates like this.

4/

To emphasize the uncertainty inherent in such predictions, a better approach is to predict a *range* of values rather than a single number.

For example, we may say the index will return somewhere in the *range* of 8% to 12% (instead of a fixed 10%) per year.

5/

10 years from now, this implies an index value in the *range* [8135, 11703]:
