Vaccination for Lectures?

Posted in Covid-19, Education, Maynooth with tags , , , , , on August 20, 2021 by telescoper

The full guidelines on the return to on-campus teaching in September that I referred to on Monday have now been distributed to all staff, not without comment.

Basically the new advice is that in-person teaching will return in September (in fact a month from today in Maynooth) for all forms of class except lectures containing over 250 people, which will be online. Lecture halls and labs will be at full capacity, i.e. with no social distancing requirement. Students will be “asked” to wear face coverings, but we are told not to attempt to enforce this. Importantly, there will be no requirement for students to have been vaccinated in order to attend lectures.

In Ireland there is a vaccination passport system so that those who wish to dine indoors at a bar or restaurant have to show vaccination status. Perhaps someone can explain to me how it makes sense for this to be a requirement in a restaurant while it is not a requirement for a student having to sit for an hour in close proximity to up to 249 others with no social distancing and no mandatory face coverings.

This conundrum is taken to another level of absurdity when you consider that a student wishing to get lunch indoors on campus will presumably have to show their vaccine passport?

There is an article here that argues that a safe return in the presence of the delta-variant requires 90% of the student population to have been vaccinated.

A more acceptable plan would have students show their vaccination status when enrolling on the course. Those who are unvaccinated but willing to have a vaccination shot could be vaccinated there and then and be allowed to attend lectures when the vaccine takes effect. Or I should say “could have been” because the facilities required to do on-campus vaccinations have not been set up and now there probably isn’t time. Those that refuse to have a vaccine should attend lectures online on a permanent basis.

(How such a scheme would be policed is a difficult question: we don’t usually have people on the doors of lecture theatres checking student IDs or anything and there is a far greater rate of traffic at the start of a lecture than you would have at a restaurant…)

There will of course be some students who are at very high risk and should not be attending lectures anyway even if vaccinated. For them we should be providing lecture recordings. Unfortunately I don’t think we have good enough facilities to record live lectures from theatres as there has been inadequate investment in cameras etc. If we’re told we have to provide lecture recordings, for many of us that means doing the lectures twice. And so our workload increases.

On the other hand it seems increasingly likely to me that all this will be irrelevant. New case numbers are running at about 1800 per day, a level that the HSE admits to being “unsustainable”. When the first colleges return in September, a substantial surge can be expected and everything will be back online anyway.

It’s like déjà vu all over again…

A Trophy for Glamorgan!

Posted in Cricket with tags , , , on August 19, 2021 by telescoper

Just a brief post but I thought I’d say something about Glamorgan’s cricketers, because it’s such a rare event and I might not get the chance to write a similar post for a while!

This evening Glamorgan actually won a trophy! They beat Durham by 58 runs in the final of the Royal London One-Day Cup (a 50 overs competition) which was held at Trent Bridge. That’s the first competition they have won since 2004.

Glamorgan batted first and managed to score 296 for 9 with skipper Kiran Carlson- who is only 23 – scoring 82 and the last pair, Carey and Hogan, putting on 33 runs. Durham were never ahead of the run rate but Sean Dickson kept them in with a chance until he ran out of partners and was sreanded in 84 not out, with the last four wickets falling for just 12 runs to leave them on 238 all out with one ball less than five overs remaining. The last wicket to fall was the hapless Chris Rushworth, out first ball caught by wicket-keeper Tom Cullen.

People will say that the Royal London Cup has been devalued by the absence of players on account of The Hundred, but that has affected all the teams and the competition has produced some really good games and I am delighted for the players to have won a trophy at last. Congratulations to them!

(It’s still not proper cricket mind….)

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , on August 19, 2021 by telescoper

Time to announce another publication in the Open Journal of Astrophysics. This one is the eighth paper in Volume 4 (2021) and the 39th in all.

The latest publication is entitled A Detailed Description of the CAMSPEC Likelihood Pipeline and a Reanalysis of the Planck High Frequency Maps. The authors are George Efstathiou and Steven Gratton of the Kavli Institute for Cosmology at the University of Cambridge.

Here is a screen grab of the overlay which includes the abstract:

You can click on the image to make it larger should you wish to do so. You can find the arXiv version of the paper here. This one is also in the folder marked Cosmology and Nongalactic Astrophysics.

This is a long and detailed paper, running to 92 pages in PDF form. Our Editorial process relies on referees being willing to volunteer their time to read and comment on submissions and this one in particular required a great deal of effort. I am always grateful to referees but in this case I am even more grateful than usual the diligence displayed during and the many useful comments received. I know who our reviewers are and they know who they are, but shall remain anonymous!

Royal Society University – Science Foundation Ireland University Research Fellowships

Posted in Maynooth with tags , on August 18, 2021 by telescoper

It is now time for a quick public information broadcast.

Did you know about the scheme run jointly between the  Royal Society and Science Foundation Ireland that enables early career researchers in Ireland access to University Research Fellowships?

This scheme provides five years of research funding (with the possibility of renewal) and has proved to be a stepping stone to their first permanent academic position for a great many scientists. Here are a couple of items about the eligibility and duration.

Eligibility:  The scheme is open to early career Post Doctoral Researchers with between 3-8 years of actual research experience since their PhD (date on which the degree was approved by board of graduate studies) by the closing date.  You cannot apply if you hold a permanent post in the university or have held (or currently hold) an equivalent fellowship that provides the opportunity to establish independence.  Please see call notes for further details.

Funding and Duration:  Funding consists of the research fellow’s salary and research expenses for an initial period of 5 years with the possibility to apply for a further 3 years.  Research expenses cover the standard consumables/materials, equipment up to €15,000, travel, training and public engagement in the first year and €13,000 thereafter.  Fellowships are expected to have commenced by October 2022.

For full details of the scheme, see here.

The scheme covers a wide range of disciplines. including physics and astronomy. Of course if you want to do cosmology, the best place here to do it is here in Maynooth! The deadline if you want to apply to hold a URF from 2022 in Ireland is 28th September 2021, which is a bit later than for the UK version but still not far off,  so please get cracking!

P.S. Five years residency in Ireland qualifies you for Irish citizenship. Just saying…

Ophelia – The Milcho Leviev Quartet, featuring Art Pepper

Posted in Jazz with tags , , , , , , on August 17, 2021 by telescoper

One of the LP records that struck a chord when I was going through my stuff in Cardiff last week was this one:

Looking back over the blog I discover that it was almost exactly ten years ago that I wrote about the very same album so I thought I’d post it again, in slightly amended form.

I first heard the track below on Humphrey Lyttelton*’s Radio 2 show The Best of Jazz, which I used to listen to every Monday night when I was at School. I must have heard this sometime around 1981, i.e. about thirty years ago. From the moment I heard the first achingly beautiful phrases of theme of this tune, called Ophelia, I was entranced and it did more than any other single record to fill me with a love of modern jazz. Although I’d always loved jazz, I had tended to think of it as music “of the past” – even the “modern” jazz of e.g. Charlie Parker fell into that category – and usually made in a recording studio. This sounded so new, so exciting, and indeed so beautiful, that it filled me with the urge to hear live jazz whenever and wherever I could. It cost me a lot of money and a lot of late nights, but I think it was worth it.

The performance was recorded live at Ronnie Scott’s Club in London in June 1980 and released on the small British record label Mole Jazz, an offshoot of the famous (and sadly now defunct) record shop of the same name that used to be on Gray’s Inn Road. I loved the track Humph played so much I got the album Blues for the Fisherman straight away (by mail order) and, although I still have it, I have almost worn it away by playing it so much. It’s a brilliant, brilliant album, with the intense atmosphere of a live performance adding to the superb playing of the musicians.

The band is listed as the “Milcho Leviev Quartet featuring Art Pepper”, although that was probably for contractual reasons, as this was the same band that toured extensively as “The Art Pepper Quartet”: Art Pepper on alto saxophone, Milcho Leviev on piano, Tony Dumas on bass and Carl Burnett on drums. I was lucky enough to see this band play live at the Newcastle Jazz festival not long after I got the record and they were great then too. Art Pepper sadly passed away in 1982.

As far as I’m aware this record wasn’t released on CD until very recently and, fortunately, a public-spirited person has put the tracks from the original album and some previous unreleased material on Youtube, so I’ve seized the opportunity to post the track which did so much to inspire me about jazz when I was 18 years old. There’s so much to enjoy in this piece, including the superb drumming of Carl Burnett and virtuosic piano of Milcho Leviev, but the star of the performance for me is Art Pepper (who also wrote the tune). His playing is at times lyrical and at times agonized, but always compelling and this band was especially good at spontaneous transitions of mood and dynamic. I love this performance, and I hope some of you will too.

P.S. Incidentally, Humphrey Lyttelton was born in May 1921 so he would have been 100 this May had he lived.

Back in the office!

Well, as promised yesterday I went back into my office at Maynooth University this afternoon. I didn’t achieve very much apart from resetting some of the sophisticated equipment (see above) but it’s a start…

To be honest I was a little distracted by the cricket at Lord’s where there was a remarkable turnaround in Indian’s favour on the last day. Looking like they were going to struggle to save the game with six wickets down for 181, a lead of just 154 overnight, and losing two quick wickets in the morning, India went on to declare on 298 for 8, then bowled England out this evening for just 120. It’s been an excellent Test Match, full of twists and turns, ending in a result that seemed very unlikely at the start of the day.

Call me old-fashioned but you can’t beat Test cricket. Nothing compares to it!

A period of readjustment..

Posted in Covid-19, Education, Maynooth on August 15, 2021 by telescoper

It’s been a rather busy weekend as I’ve tried to complete the grading my repeat examinations. I’m almost done but I have six more scripts to do, which I will finish tomorrow morning. Once again I’ve set a bad example by being later than everyone else, but at least I’m not going to miss the deadline. We have our Examination Board on Friday and they’ll all be done and dusted by then.

Friday is 20th August, which means it’s exactly a month from then until the start of teaching in Semester 1 of the new academic year. We have now received draft instructions on how this is planned to start. They are not in final form yet, having been circulated to Heads of Department for comments. I’ll refrain from saying more in public until they are published but in a nutshell we are anticipating more-or-less a full return to on-campus teaching with no reduced capacity in lecture theatres but with slightly shorter lectures and staggered start and end times.

That is if everything is under control in a month. The latest Covid-19 figures are not reassuring. The latest 7-day rolling average is about 1800 new cases to day, which is as high as it was in January. Hospitalizations are increasing, though at a lower level than before presumably because of the vaccination effect. Mortality rates are unclear (to me) because of the continuing disruption to reporting caused by the HSE computer problem. I’m very conscious that all our plans were changed at the last minute at the start of last academic year, so we’ll just have to wait and see. Hopefully the incidence rate will stop rising over the next few weeks.

On Friday I took a prospective PhD student and his family for a walk around campus, mainly to introduce them to the famous Library Cat (who is fine, by the way, but bothered by wasps getting into his dish when I fed him). Most staff and research students in the Department are still working from home, but there were one or two people around to say hello. When I entered my office I saw I hadn’t changed the date on my calendar since June 15th, two months ago. By the look of the sports fields at the back of the college they haven’t been mown for much longer than that: at the moment they look more like hayfields!

I have been fairly content working from home over the summer (with two interruptions for travelling to Cardiff and back), but I really have to get into the habit of going to the office if we’re going to welcome students in person. I think when I’ve finished my marking tomorrow morning I’ll start trying to get back into the routine. For one thing quite a few things we moved before lockdown need to be moved back to their proper places. When I was waiting for the train from Cardiff on Thursday I saw railway workers removing the social distancing signs from the platform. I guess we’ll be doing that too.

I do hope all this isn’t premature, but I have a nagging feeling…

Happy 30th Birthday to the arXiv!

Posted in Biographical, Open Access, The Universe and Stuff with tags , , , on August 14, 2021 by telescoper

I was reminded yesterday that today, 14th August, is the 30th anniversary of the start of the arXiv so I thought I’d send a quick birthday greeting to mark the occasion. In case you weren’t aware, arXiv is a free distribution service and an open-access archive containing (currently) 1,928,825 scholarly articles in the fields of physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics.

There was a precursor to the arXiv in the form of an email distribution list for preprints, but arXiv proper started on 14th August 1991. It was based at Los Alamos National Laboratory (LANL) with a mirror site in SISSA (Trieste) that was used by those of us in Europe. In the beginning, arXiv was quite a small-scale thing and it wasn’t that easy to upload full papers including figures. In fact the SISSA system was run from a single IBM 386 PC (called “Babbage”). As it expanded, the running of arXiv was taken over Cornell University. You can read more about the history here.

You have to remember that journals didn’t generally have electronic submission in those days: you had to send paper manuscripts in the post to the Editorial office. Likewise many of us carried on sending out paper preprints for some time after the arXiv was set up. Younger researchers should be grateful they don’t have to put up with the absolute chore of producing papers the old-fashioned way!

The astrophysics section of arXiv (“astro-ph”) started in April 1992. Although astrophysicists generally were quick to latch on to this new method of distributing preprints, it took me a little time to get onto arXiv: my first papers did not appear there until February 1993; my first publication was in 1986 so there are quite a few of my early papers that aren’t on arXiv at all. In 1993 I was working at Queen Mary & Westfield College (as it was then called). I was working a lot with collaborators based in Italy at the time and they decided to start posting our joint papers on arXiv. Without that impetus it would have taken me much longer to get to grips with it.

In case you’re interested, my first paper to appear on the arXiv was this one on 23rd February 1993 but it was followed a day later by two others, this one and that one. I don’t remember very well, but this was an exercise in catching up and all three of those papers were actually published in journals before we put them on arXiv. It was only later that we got into the habit of posting papers on arXiv at the same time as submitting to a journal, which I think is the best way to do it!

The Open Journal of Astrophysics would not have been possible without the arXiv but in a wider sense the astrophysics community has a very great deal to thank the arXiv for, but remember that it is funded by donations and is run on a shoestring. If you agree that it’s a tremendously useful asset for your research then please consider making a donation.

Kush – Art Blakey & Buddy De Franco

Posted in Biographical, Jazz with tags , , , , on August 13, 2021 by telescoper

One of the things I did during my recent visit to Wales was to pack up my old vinyl LPs for removal to Ireland. I have quite a lot of them on digital formats now but that’s not true of all of them so I’m looking forward to listening to the others very soon.

I bought this particular album Blues Bag as a curiosity as it features the unlikely combination of Buddy De Franco on clarinet (bass clarinet on several tracks, including the one below) and Art Blakey on drums.

Whatever I thought the combination of the smooth style and impeccable technical virtuosity of Buddy De Franco with the powerful and aggressive drum foundryman Art Blakey would be like before I bought the LP, when I first heard it the thing that struck me was how superbly they complemented each other.

Anyway, I thought I would post a track so you can decide what you think. This is Dizzy Gillespie tune called Kush. I think this version is great, with very fine work on the drums by Blakey.

New Publication at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , on August 13, 2021 by telescoper

Back from my short trip, I now have time to announce another publication in the Open Journal of Astrophysics. This one was published at the end of last month, but owing to the holiday season there was a delay in activating the DOI and registering the metadata  so I have delayed posting about it until just now. It is the seventh paper in Volume 4 (2021) and the 38th in all.

The latest publication is entitled A Differentiable Model of the Assembly of Individual and Populations of Dark Matter Halos. The authors are Andrew P. Hearin,  Jonás Chaves-Montero, Matthew R. Becker and Alex Alarcon, all of the Argonne National Laboratory.

Here is a screen grab of the overlay which includes the abstract:

You can click on the image to make it larger should you wish to do so. You can find the arXiv version of the paper here. This one is also in the folder marked Cosmology and Nongalactic Astrophysics.

We’ve had a bit of a surge in submissions over the last few weeks – no doubt due to authors using their “vacation” to finish off papers. August is not the best month for finding referees, but we’ll do our best to process them quickly!
