2020 marks the start of the quantum dot revolution.

Completely ignoring the fact that "photocatalytic generation of reactive oxygen species (ROS) from quantum dots (QDs) has been widely reported."

Results: It was found that whereas singlet oxygen (1O2) was not produced by photoexcited QDs, superoxide anion(O2− )and hydroxyl radicals(OH) were generated by QDs, especially in the presence of a physiological concentration of electron donating agent including NADH.

Using cell metabolic activity assays and various probes of ROS generation, the formation of ROS in cellular environments was demonstrated.

Conclusion: Illumination of QD-treated cells and bacteria with light did affect viability. The above results, together with those of assays in the presence of various scavengers of specific ROS, indicate that the formation of ROS by QDs mainly proceeded via electron transfer.

A statement about Stephanie Hayden.

In January I became aware that Ms Hayden (who monitors this account despite being blocked) had made a series of defamatory allegations about myself and my wife.

The allegations were made on Twitter, via Hayden’s account, and were widely retweeted.

The allegations were that as a result of her making a police complaint, (1) the police were seeking to urgently speak to me.

Furthermore (2) that police has spoken to me on 26/12/20 and offered some kind of “robust” advice about my conduct on and off line.

Finally (3) that police attended my home address in November, where my wife mislead them as to my whereabouts.

Hayden commented about this at length on Twitter, said that both and I am my wife had lied, and that I had even given a false address in Hampshire.

I said at the time all the allegations were false.

The police “complaint” was nothing more than Hayden making yet another vexatious complaint to the police, as Hayden routinely does.

The police did not speak to me on 26/12/20, as alleged, or at all.

I have documented this in many threads which I will post here just to annoy everyone.

THREAD: On the full-fledged process of responding to a Revise-And-Resubmit (R&R).

I have written pieces of the process, but I hadn't actually written a thread or a blog post showcasing how all my blog posts fit with one another. I teach this process when I give workshops.

So here's what I do (now), and let me share a lesson from my past lives:

DO NOT SIT ON R&Rs.

I know, they're painful and scary and sometimes we don't know if our paper will get rejected in the end.

But remember, an R&R means an OPPORTUNITY to get your paper published.

Sitting on R&Rs, leaving them for later, and not prioritizing them has gotten me fewer publications. I know this for a fact. I am not ashamed of admitting that I have sometimes felt that I will not be capable of responding to multiple (often conflicting) comments.

HOWEVER...

Sustained, frequent advice from professors who are senior to me (though I am senior myself now too) is always the same and on-point:

The goal is the R&R.

You're not getting a desk rejection.

You are getting your work read, reviewed carefully, thought about, responded to.

What do I do now (and have been doing for the past few years, with success)

When I get the R&R (the "decision letter"), I make sure to calm down, because I am always afraid I'm going to get nasty comments. These have been (luckily) very rarely present in my latest submissions.

For fun I made a Robinhood account. It took me 5 minutes to sign up, get approved and transfer funds for trading...

Here's some details... Read on.

...it took me another 5 minutes to get qualified for options.

If I share a sign up I get "free shares" and I can share as much as I want up to 500$ worth.

The main UI has a prepopulated "list" of stocks/crypto to watch and links to news.


Clicking a stock opens a "trade" button that looks like this.

Notice options is first, buy second.

Options took me to an approval process (which took about a minute) and now away I go trading Baba options.


Buying stock looks like this. It emphasizes fractional shares.

Surkanda devi mandir is a famous shrine of Hindus located near Kaddukhal distt of Uttarakhand, 11 Km from the town of Dhanaulti and 35 Km from Mussoorie.
The Temple is one of the 51 Shakti Peethas spread all over Indian Subcontinent and is dedicated to Goddess Surkanda.


Nestled on a Hill at an Altitude of 2700 m approx, the place offers a splendid view of the snow capped mountains, the picturesque scenic beauty that offers an experience of the lifetime.
The Temple build in the traditional Garhwal style exuberates the Architectural splendour.


The origins of the Surkanda Mata Mandir is attributed to Goddess Sati, consort of Bhagwan Shiv who in a rage immolated herself in her arrogant Father Daksha's Yajna Kund bcoz he didn't invite Bhagwan Shiv in the Yajna.


Devastated by the death of Sati Shiva wandered all over the cosmos performing Tandava-The Dance of Cosmic Destruction.Fearing the total annihilation of cosmos, Gods requested Bhagwan Vishnu to pacify Shiva.Bhagwan Vishnu then used his discuss to destroy the burning corps of Sati.


The pieces of Sati Mata's body then got scattered all over the region which were later established as Shakti Peethas by Bhagwan Shiva himself.Its believed that the head of Sati fell here and it was called Sirkhanda Mata Temple before, but with passage of time it became Surkanda.

Ancient Egypt was the most advanced civilization in the ancient world. Why was Egypt so special?

There are so many firsts in Egypt that we all know about, and that makes Egypt unique. For example, the Sumerians did not build the pyramids of Egypt.

Again, at such a key moment in UK and at such high political levels, evidence of deep misunderstanding of EU: The PM is under pressure in some quarters to delay #Brexit vote to allow her first to “improve” deal in Brussels BUT EU is determined not to budge at this stage

2) All EU leaders watching tomorrow’s vote. Of course they want to avoid a no deal #Brexit BUT they feel the deal - so painfully negotiated between EU and UK - is too fresh to re-open. Clarifications, yes but fundamental renegotiations, no.

3) The EU’s international reputation as a tough deal-maker is at stake here too. If Brussels now suddenly “gives in” to U.K. on EU red lines (eg backstop) then that would weaken the EU’s reputation in future trade negotiations with other non EU countries

4) Also on backstop the EU is unlikely to cave in to favour a relationship with a leaving member state (UK) against the explicit wishes and ignoring the deep concerns of a continuing member: Ireland.

5) Both the EU and the PM signed up to a guarantee to protect the border between Northern Ireland and the Republic of Ireland. If either the U.K. or EU can leave the backstop unilaterally then this clearly is no longer a guarantee.

An interesting set of games that I've been vaguely interested in since I was a kid, after seeing one at a friend's house and never being able to find it again, was the BATTLES IN A DISTANT DESERT/BATTLES ON DISTANT PLANETS series.


These are turn-based wargames for windows 3.x, sharing the same engine.
Battles in a Distant Desert is from 1992, and is based on the first Iraq war (Desert Storm)


and Battles on Distant Planets is from 1991, and takes place in SPACE!
I'm pretty sure this is the one I played as a kid.


They've got 3 options to play with:
* Player vs. Player
* Player vs. Computer
* Computer vs. Computer

So it's a 0-2 player game!


They also did a DOS strategy game called "STARDATE 2140.2: GALACTIC CONQUEST" in 1990, but it seems to be lost.
All the games share an experimental AI system based on neural networks.
