Rational points on hyperelliptic Atkin-Lehner quotients of modular curves and their coverings
We complete the computation of all Q-rational points on all the 64 maximal Atkin-Lehner quotients X0(N)∗ such that the quotient is hyperelliptic. To achieve this, we use a combination of various methods, namely the classical Chabauty–Coleman, elliptic curve Chabauty, quadratic Chabauty, and the bielliptic quadratic Chabauty method (from a forthcoming preprint of the fourth-named author) combined with the Mordell-Weil sieve. Additionally, for square- free levels N, we classify all Q-rational points as cusps, CM points (including their CM field and j-invariants) and exceptional ones. We further indicate how to use this to compute the Q-rational points on all of their modular coverings
Does publicity about cancer screening raise fear of cancer? Randomised trial of the psychological effect of information about cancer screening
Flexible Sigmoidoskopie kann viele Leben retten
Atkin W et al. Long term effects of once-only flexible sigmoidoscopy screening after 17 years of follow-up: the UK Flexible Sigmoidoscopy Screening randomised controlled trial. Lancet 2017; 389: 1299–1311
Die Beobachtungsdauer zur Darmkrebsfrüherkennung mittels einer flexiblen Sigmoidoskopie im Alter zwischen 55 und 64 Jahren liegt inzwischen in Großbritannien bei 17 Jahren. Die von Wendy Atkin von der Cancer Screening and Prevention Research Group am Imperial College in London und Kollegen vorgestellten Ergebnisse bestätigen den Effekt des Darmkrebsscreenings mittels Endoskopie selbst bei einer einmaligen und begrenzten Maßnahme wie dieser.

Neurophysiological, psychological and immunological evaluation of Irritable Bowel Syndrome
Irritable
Bowel
Syndrome
(IBS)
is
a
common
gastroenterological
disorder
characterised
by
recurrent
abdominal
pain
and
a
change
in
bowel
habit.
Diagnosis
is
made
with
reference
to
clinical
symptomatology
and
the
exclusion
of
other
competing
disorders.
As
such
there
is
no
reliable
biomarker
in
the
clinical
field
to
prove
or
disprove
the
diagnosis.
This
has
obvious
implications
for
the
treatment
of
the
syndrome.
Recent
research
has
targeted
the
immunology
of
IBS
to
see
if
changes
in
cytokine
expression
support
the
concept
of
a
chronic
low-level
inflammatory
state.
IBS
has
a
strong
association
with
psychological
comorbidity.
Visceral
hypersensitivity
is
also
a
hallmark
of
the
disease.
This
study
was
constructed
to
compare
the
psychological
profiles
of
patients
with
IBS
against
a
control
group;
to
use
cortical
evoked
potentials
to
observe
the
cortical
representation
of
an
electrical
rectal
stimulus
to
see
if
changes
in
amplitude
or
latency
might
be
suggestive
of
enhanced
afferent
nerve
transmission;
and
to
use
cytokine
analysis
of
stimulated
and
un-stimulated
peripheral
blood
mononuclear
cells
to
study
the
inflammatory
response
Modular symbols over number fields
Let K be a number field, R its ring of integers. For some classes of fields, spaces of cusp forms of weight 2 for GL(2;K) have been computed using methods based on modular symbols. J.E. Cremona [9] began the programme of extending the classical methods over Q to the case of imaginary quadratic fields. This work was continued by some of his Ph.D. students [35, 6, 22], and results have been obtained for some imaginary quadratic fields with small class number. More recently, P. Gunnells and D. Yasaki [18] have developed related algorithms for real quadratic fields.
The aim of this thesis is to contribute to the extension of the modular symbols method, when possible developing algorithms and implementations for effective computations. Some parts of the theory are purely algebraic and can be extended to all number fields. We generalise the theory for cusps and Manin symbols; we also describe a generalisation of Atkin-Lehner involutions and study other normaliser elements. On the other hand, all previous explicit computations for the imaginary quadratic field case were done only for specific fields. In the last part of this thesis we begin work towards a general implementation of the techniques used in this case. In particular, we are able to compute a fundamental domain of the hyperbolic 3-space for any imaginary quadratic field.
Implementations of the algorithms described in this thesis have been written by the author in the open-source mathematics software Sage [31]
