Burkitt's Lymphoma in a pregnant woman: case report and review of the literature
"Burkitt’s lymphoma (BL) is an aggressive B-cellmalignancy with very high proliferation rate,more common inmales than females.
Here, we describe a case of Burkitt’s lymphoma in a 24-week pregnant woman with cervical and abdominal involvement. The
common genetic event of virtually all BL is a reciprocal chromosomal translocation involving the proto-oncogene MYC and one
of the Ig gene heavy or light chain loci. Supportive treatment was administered until early delivery, after which the patient was
treated according to protocol LMB96. Pregnancy and tumorogenesis share some important events such as immunologic tolerance,
angiogenesis, and editing the host immune response. Little is known about the relationship between these events in pregnancy and
in tumorogenesis.

Concept logic trees: enabling user interaction for transparent image classification and human-in-the-loop learning
Interpretable deep learning models are increasingly important in domains where transparent decision-making is required. In
this field, the interaction of the user with themodel can contribute to the interpretability of themodel. In this research work, we
present an innovative approach that combines soft decision trees, neural symbolic learning, and concept learning to create an
image classificationmodel that enhances interpretability and user interaction, control, and intervention. The key novelty of our
method relies on the fusion of an interpretable architecture with neural symbolic learning, allowing the incorporation of expert
knowledge and user interaction. Furthermore, our solution facilitates the inspection of the model through queries in the form
of first-order logic predicates. Our main contribution is a human-in-the-loop model as a result of the fusion of neural symbolic
learning and an interpretable architecture.We validate the effectiveness of our approach through comprehensive experimental
results, demonstrating competitive performance on challenging datasets when compared to state-of-the-art solutions.HAT.tec GmbHFunding for open access publishing: Universidad de Granada/CBUA

ARCHI: pipeline for light curve extraction of CHEOPS background star
High precision time series photometry from space is being used for a number
of scientific cases. In this context, the recently launched CHEOPS (ESA)
mission promises to bring 20 ppm precision over an exposure time of 6 hours,
when targeting nearby bright stars, having in mind the detailed
characterization of exoplanetary systems through transit measurements. However,
the official CHEOPS (ESA) mission pipeline only provides photometry for the
main target (the central star in the field). In order to explore the potential
of CHEOPS photometry for all stars in the field, in this paper we present
archi, an additional open-source pipeline module{\dag}to analyse the background
stars present in the image. As archi uses the official Data Reduction Pipeline
data as input, it is not meant to be used as independent tool to process raw
CHEOPS data but, instead, to be used as an add-on to the official pipeline. We
test archi using CHEOPS simulated images, and show that photometry of
background stars in CHEOPS images is only slightly degraded (by a factor of 2
to 3) with respect to the main target. This opens a potential for the use of
CHEOPS to produce photometric time series of several close-by targets at once,
as well as to use different stars in the image to calibrate systematic errors.
We also show one clear scientific application where the study of the companion
light curve can be important for the understanding of the contamination on the
main target.Comment: 14 pages, 13 figures, accepted for publication in MNRAS, all code

Modulation scheme for the bidirectional operation of the Phase Shift Full Bridge Power Converter
This paper proposes a novel modulation technique for the bidirectional operation of the Phase Shift Full
Bridge (PSFB) DC/DC power converter. The forward or buck operation of this topology is well known and widely used in
medium to high power DC to DC converter applications. In contrast, backward or boost operation is less typical since it
exhibits large drain voltage overshoot in devices located at the secondary or current-fed side; a known problem in isolated
boost converters. For that reason other topologies of symmetric configuration are preferred in bidirectional applications,
like CLLC resonant converter or Dual Active Bridge (DAB). In this work, we propose a modulation technique
overcoming the drain voltage overshoot of the isolated boost converter at the secondary or current-fed side, without
additional components other than the ones in a standard PSFB and still achieving full or nearly full ZVS in the primary
or voltage-fed side along all the load range of the converter. The proposed modulation has been tested in a bidirectional
3.3 kW PSFB with 400 V input and 54.5 V output, achieving a 98 % of peak efficiency in buck mode and 97.5 % in boost
mode operation. This demonstrates that the PSFB converter may become a relatively simple and efficient topology for
bidirectional DC to DC converter applications
“Eu vos apresento o super-homem (morcego)” : uma comparação entre o Batman, de Frank Miller, e o Übermensch, de Nietzsche
O presente trabalho tem por objetivo aproximar as semelhanças entre a graphic novel O Cavaleiro das Trevas de Frank Miller e a filosofia do Ăśbermensch, apresentada por Zaratustra, na obra Assim Falou Zaratustra de Friedrich Nietzsche, relacionando os elementos da filosofia nietzschiana com o enredo e os personagens de Miller. Para isso, será feita uma leitura comparativa entre a obra de Miller e o prĂłlogo da obra de Nietzsche, realizando assim uma aproximação entre ambas. O modo como o Batman se desenvolve na graphic novel, se tornando um sĂmbolo para Gotham, comparado com o prĂłlogo da obra de Nietzsche pode lançar alguma luz para como deveria ser o “Übermensch” de Nietzsche na sociedade atual, ao mesmo tempo em que aborda impasses polĂticos e culturais da sociedade contemporânea.The present work aims to a bring together the similarities between the graphic novel The Dark Knight Returns, by Frank Miller and the Ăśbermensch philosophy, presented by Zaratustra in the book Thus Spoke Zaratustra, by Friedrich Nietzsche, relating the elements of the Nietzschean philosophy and Miller’s plot and characters. To do it, a comparative reading between Miller’s work and the prologue of Nietzsche’s book will be made, thus making the relation between them. The way Batman develops himself in the graphic novel, and become a symbol to Gotham city, compared to Nietzsche’s work prologue may help to understand how Nietzsche’s “Übermensch” should be in the current society, while, at the same time, it approaches political and cultural impasses of contemporary society
