Hi all,
Due to some unforeseen circumstances we have to postpone today's seminar
- We will reschedule and update you in next week's update bulletin.
Best wishes,

Hello all,
We are holding the next meeting of the YNIC Science Committee next Monday.
Please send any items you would like me to raise by Thursday so I can add
them to the agenda.
Thanks

Hello All,
We have a Heating and Cooling contractor in attendance today. Alarms may
sound. Apologies if they disrupt your work. If an alarm does and stops
within 30s there is no need to act. Please be aware that staff may need to
ask you to leave at short notice.
Thanks

Hello All,
Two things this week
1) The will be a seminar held in the Chemistry Department this week that
may interest users:
Dr Luisa Ciobanu: Functional MRI at ultra-high magnetic fields
Wednesday 4th October 13.00-14.00
In room Chemistry/B101
Abstract
Despite the fact that BOLD-fMRI is routinely used to map brain activity and
connectivity in preclinical and clinical settings its exact relation with
the underlying microscopic changes, either vascular or neuronal, is still
not fully elucidated. The development of high magnetic fields promise
substantial improvements in the contrast to noise ratio and the spatial
resolution with which functional MRI maps are acquired possibly allowing
the comparison with other, microscopic, techniques.
In the first part of my talk I will review the advantages, but also the
challenges, imposed by imaging at ultra-high magnetic fields. Following
this, I will present recent results demonstrating that BOLD fMRI faithfully
reports microvascular hyperemia, and that the detection of the smallest
neuronal activation is limited only by its sensitivity.
Beside improved BOLD acquisitions, high magnetic fields allow the
development of other alternative ways for studying neuronal activation. In
the last part of my presentation, I will describe a novel metabolic imaging
approach, based on Chemical Exchange Saturation Transfer (CEST), for
assessing the changes induced by neuronal stimulation in rat brains at
17.2T. Specifically, I will present images acquired under
glucose-sensitizing conditions showing a significant negative contrast that
highlights the same brain regions as those activated in conventional BOLD
maps.
2) We are to give 'Tips of the week', hopefully, as the name suggests on a
weekly basis. This will largely give advice on IT tricks and work-arounds
for commonly occurring analysis tasks. Here's this week's:
Scenario: You've submitted a load of jobs to the cluster which you find out
will be of no use to you and you want to bring them to a halt.
Solution
typing: qdel -u <username> into a terminal will stop all cluster jobs
submitted by that user, e.g.
qdel -u ddc506

Dear All,
We have put together a provisional schedule for the YNiC seminars for
the academic year. The YNiC led seminars will occur on even weeks
during the autumn and spring terms. On the odd weeks we will have
seminars on an ad-hoc basis and will largely focus on project
presentations or presentations arranged by the YNiC Science Committee.
We have also scheduled training opportunities for scanner operators. We
would really like new PhD students and postdocs who will want to operate
the scanners to take these opportunities as they dovetail nicely into
our workload and MSc teaching and training. With that in mind, please
note that the first element of training will be held Thursday 28th
September.
The detailed schedule is attached.
Best wishes

Hello All,
This week we will be having induction sessions for our new intake of PhD
and MSc students between 9am and 1pm on Thursday. An introduction to the
IT systems will take place between 9am and 1pm on Friday. It will,
therefore, be busier than usual in open plan, so please take that into
account when planning your work at YNiC.
We are hoping to freshen up the posters at YNiC over the next week or so.
Could you bring us any spare, but relatively recent, posters that you would
like to have on display at YNiC?
Many thanks
Tony

Hello All,
Thanks to those of you who have reported issues arising after the IT
upgrade. We have managed to deal with the majority of them. A reminder
for those of you who haven't given your analysis or stimuli a spin for a
while to give them a go well in advance of needing them, so we can help
with any issues that arise.
Next week is the start of term and therefore ynic will be busy with
inductions and teaching. If you are here, please join us in welcoming our
new recruits.
Best wishes

Dear All,
A few updates:
1) Staff changes: Ross Devlin has now left YNiC. He will be having a
period of leave before taking up his new role at York Instruments. He has
given YNiC many years of valuable and helpful service for which we are all
very thankful.
2) A brief reminder that there will be no operator cover for any scanner on
Wednesday this week. We are undertaking some training that will look at
the documentation and processes we use to train operators for the Siemens
scanner.
3) Project booking limits: We have a standard limit of 7 hours per week per
project. We are aware however that such limits can constrain throughput on
projects. We can offer some flexibility on how much time can be booked if
we are given a period of time to plan. So, please get in touch should your
requirements for booking be greater than 7 hours per week.
Best wishes

Hello All,
1) Please test stimulus code and analysis streams you rely on and feedback
any errors (including the error report) through the IT system. Note that
it is not a safe assumption that all code will run perfectly after an IT
upgrade.
2) We will be closed from 1330 on Thursday.
3) Next Wednesday 13th September, we will be closed from midday to test out
training materials for the Siemens scanner.
Best wishes

Hello everyone,
Just a reminder that if anybody has any suggestions for discussion topics
for the YNIC Science Committee, they should contact me to let me know.
Please feel free to contact me either via email or in person to discuss any
issues that you would like raised at the next meeting.
Best wishes,
Jonny
