description: The epoch of reionization and formation of first stars are inter-linked topics that are of considerable interest. We use a simplified approach for studying formation of stars in collapsed haloes, and the resulting ionization of the inter-galactic medium (IGM). We consider a set of LCDM models allowed by observations of CMB temperature and polarization anisotropies for this study. We constrain parameters related to star formation with the help of observations. We constrain subsets of these parameters independently by using the observed metallicity of the inter-galactic medium at z ~ 5 and the requirement that the Thomson scattering optical depth due to an ionized IGM as determined for the model from CMB observations be reproduced. We consider a range of initial metalicities for star forming gas, and some variations of the initial mass function of stars. We find that a "normal" initial mass function (IMF) may satisfy these two constraints with a raised efficiency of star formation as compared to that seen in the local universe. Observations require a significant fraction of metals to escape from haloes to the IGM. We can also place constraints on the ratio of escape fraction for metals and ionizing photons, we find that this ratio is of order unity for most models. This highlights the importance of using the constraints arising from enrichment of the inter-galactic medium. (Abridged)

description: Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), are chronic, progressive and relapsing inflammatory disorders of unknown etiology. UC is characterized by inflammation of the large bowel mucosa and submucosa, whereas in CD inflammation is trans-mural and may involve various sites of the gastrointestinal tract. Superficial mucosal lesions are most prone to heal, whereas deep ulcers or transmural fissures may heal with more difficulty and may be followed by the development of fibrosis and strictures requiring surgery. Inflammation appears to be necessary to trigger the onset of the fibrotic process, but subsequently plays a minor role in its progression. In IBD, anti-inflammatory treatment does not prevent evolution of fibrosis once the process has started. Therefore, the mechanisms that regulate fibrosis appear to be distinct from those regulating inflammation. Intestinal fibrosis is due to an abnormal accumulation of extracellular matrix proteins producted by activated intestinal myofibroblasts. Increased evidence indicate that a number of molecules are involved in the development of the disease and a crosstalk between TGFβ/Smads pathway and αvβ6 integrin, mTOR and PPARγ could play a crucial role in the development of intestinal fibrosis. Animal models represent a useful tool to investigate the molecular and cellular mechanisms of intestinal inflammation and fibrosis and to test the effectiveness of novel therapeutic strategies for the prevention and treatment of intestinal fibrosis that still remain the major cause of surgical intervention.

description: BaNi$_2$As$_2$ exhibits a first order structural transition at 130 K. Understanding this structural transition is a crucial step towards understanding the electronic properties of the material. We present a combined optical spectroscopy and band structure calculation study on the compound across the transition. The study reveals that BaNi$_2$As$_2$ is a good metal with a rather high plasma frequency. The phase transition leads to a small reduction of conducting carriers. We identify that this reduction is caused by the removal of several small Fermi surface sheets contributed dominantly from the As-As bonding and Ni-As antibonding states.

Heroines of Hunger Relief: Challenging Feminization of Famine in Twenty-First Century Cultural Archive(s)
Creators: name: Steiner, Daria
Publisher: name: Diffractions
Year: 2021

description: Female heroes of the Great Irish Hunger and its aftermath (1845–1852) have received little attention in popular culture and historiography. Extant portrayal of women of this period is to this day dominated by stereotypical tropes of passive victimization and suffering. This article links this phenomenon to the notion ‘feminization of famine’ (Kelleher 1997) and examines how contemporary literature challenges archival absences of alternative female roles through different manifestations of nineteenth-century female heroism. Proposing to interpret literary fiction as both an agent of alternative cultural archive and a source of cultural conceptions of the heroic, the article zooms in on Emma Donoghue’s novel The Wonder (2016). A close reading of its female characters reveals that contemporary literature subverts female imagery based on victimization and suffering. Instead, it promotes heroic figures that foster hunger relief and defy expected gender roles in hunger crisis scenarios. Supplementing the analysis with recent representations of female heroes in new digital Famine archives, the article concludes that future cultural production will be increasingly interested in potential parallels between nineteenth-century female heroism and recent crises such as the global pandemic.

Publisher: name: University of British Columbia
Year: 2012

description: The pyrolysis of methane diluted with nitrogen at 1200°C and 1.00 atm total pressure was investigated in a flow reactor made of alundum. The reaction is unaffected by a carbon surface but slightly catalyzed by an alundum surface. The initial rate of decomposition of methane is governed by -(dPCH₄/dt) = 5.7 PoCH₄ (atm/sec) for partial pressures ranging from 0.100 to 0.672 atm. The experimental pressure-time curves for methane up to 0.70 atm, acetylene up to 0.010 atm, hydrogen up to 0.30 atm, and time up to 0.05 sec were reproduced by the following equations: [ Formulas omitted ] An autocatalytic effect of acetylene, represented by the empirical equation (dPC₂H₂/dt )= (0.00586)(32.3) PCH₄ + [32.3 - 4.80(1+PoCH₄)]PC₂H₂ was observed in the initial stages of the reaction.

description: The observed preponderance of ground states with angular momentum L=0 in many-body quantum systems with random two-body interactions is analyzed in terms of correlation coefficients (covariances) among different eigenstates. It is shown that the geometric analysis of Chau {\it et al.} can be interpreted in terms of correlations (covariances) between energy eigenvalues thus providing an entirely statistical explanation of the distribution of ground state angular momenta of randomly interacting quantum systems which, in principle, is valid for both fermionic and bosonic systems. The method is illustrated for the interacting boson model.

Inherited Stories of the Salto – the Leap: The Clandestine Journey of Portuguese Migrants to France in the 1960-1970s & José Vieira’s People from the Salto
Creators: name: Pinto, Sofia
Publisher: name: Diffractions
Year: 2021

description: In the 1960-1970s, approximately 900,000 Portuguese people migrated to France, fleeing poverty, colonial war, and dictatorship. Many were clandestine and had to illegally cross the borders between Portugal and Spain, and then between Spain and France, in a voyage known as the salto – the leap. Stories of the salto are present in family circles of remembrance, as memories of migration are transferred to the second and third generations. In a context of postmemory, many descendants of the first generation of migrants inherit these stories imbued with trauma and are currently striving to give them visibility and recognition on a national level in Portugal. This task seeks to forge a collective memory by retrieving personal accounts and can be accomplished through cultural and aesthetic practices such as filmmaking. I consider the latter alternative archives that provide affective, intimate, and affiliative readings of the past countering national and official narratives. To illustrate this process, I analyze José Vieira’s documentary DVD film collection and booklet, People from the Salto.

Dendritic cells: phenotypic and functional heterogeneity

Subjects: dendritic cells history; myeloid dendritic cells; in vitro differentiation; plasmacytoid dendritic cells; immune response; tolerance

description: Dendritic cells are specialized to capture antigens, process them and present them to T cells to initiate, regulate and fine tune immune responses towards pathogens and tumours. The story of these cells began more than forty years ago and the interest for them is ever growing because of their central role in immunobiology. Dendritic cells are heterogeneous for origin, anatomical localization, phenotype and function: several subsets of myeloid dendritic cells and plasmacytoid dendritic cells have been recognized until now. Dendritic cells differentiate from haematopoietic stem cells-derived precursors, migrate from sites of antigen uptake to lymphoid organs and during this process mature to antigen presenting cells capable of interacting with lymphocytes and stimulate both immune response and peripheral tolerance to self. Since dendritic cells play crucial roles in infection, cancer, allergy, autoimmunity and graft rejection, thorough knowledge of their subsets and behaviour will open the path to tools allowing better control of many clinical conditions.

description: We introduce the radio reconfigurability thanks to IRUWB mostly digital architecture for MANET context. This particular context implies some constraints on the radio interface such as low cost, low power, small dimensions and simplicity. Here, we propose an implementation of dynamic reconfigurable receiver on ASIC, and FPGA, after having explained the advantages of mostly digital radio for reconfigurability. In this paper, by studying our prototypes, we could prove that reconfigurability is on the contrary with MANET constraints needs. The proposed solution allows data rate, radio range, energy and spectrum occupation reconfigurability.

Translation in Progress: The Manuscript of “O Corvo” by Fernando Pessoa
Creators: name: Defenu, Carlotta
Publisher: name: Diffractions
Year: 2021

description: Among the large number of critical-comparative studies devoted to Fernando Pessoa's translation of Edgar Allan Poe's poem “The Raven,” the autograph manuscript draft of “O Corvo” has never been subject to in-depth critical genetic investigation. In the last two decades, the development of a research field dedicated to translation genetics provided the methodological bases and established the main objectives for the analysis of translated texts in a genetic approach. Considering the research purposes of genetic translation studies, in this article it will be shed light on the compositional process that led to the publication of Pessoa’s “O Corvo.” In this regard, the manuscript kept in Fernando Pessoa’s archive is to be deemed as privileged material for the study of the Portuguese poet’s translation practice, allowing us to observe the empirical application of Pessoa’s translation strategies and to give a new perspective to the critical interpretation of “O Corvo.”

Effects of partitioning and extrapolation on the connectivity of potential magnetic fields

description: Coronal magnetic field may be characterized by how its field lines interconnect regions of opposing photospheric flux -- its connectivity. Connectivity can be quantified as the net flux connecting pairs of opposing regions, once such regions are identified. One existing algorithm will partition a typical active region into a number of unipolar regions ranging from a few dozen to a few hundred, depending on algorithmic parameters. This work explores how the properties of the partitions depend on some algorithmic parameters, and how connectivity depends on the coarseness of partitioning for one particular active region magnetogram. We find the number of connections among them scales with the number of regions even as the number of possible connections scales with its square. There are several methods of generating a coronal field, even a potential field. The field may be computed inside conducting boundaries or over an infinite half-space. For computation of connectivity, the unipolar regions may be replaced by point sources or the exact magnetogram may be used as a lower boundary condition. Our investigation shows that the connectivities from these various fields differ only slightly -- no more than 15%. The greatest difference is between fields within conducting walls and those in the half-space. Their connectivities grow more different as finer partitioning creates more source regions. This also gives a quantitative means of establishing how far away conducting boundaries must be placed in order not to significantly affect the extrapolation. For identical outer boundaries, the use of point sources instead of the exact magnetogram makes a smaller difference in connectivity: typically 6% independent of the number of source regions.

How do we know what aspects of gross anatomy to teach to our students? Can core syllabuses for the anatomical sciences be developed and accepted?
Creators: name: Moxham, Bernard John
Publisher: name: Italian Journal of Anatomy and Embryology
Year: 2015

description: There is increasingly a call for clinical relevance in the teaching of the biomedical sciences within all health care programmes. This presupposes that there is an understanding of what is “core” material within the curriculum. To date, the anatomical sciences have been poorly served by the development of core syllabuses, although there have been commendable attempts to define a core syllabus for gross anatomy in medicine and for some medical specialties. The International Federation of Associations of Anatomists (IFAA) and of the European Federation for Experimental Morphology (EFEM) aims to formulate, on an international basis, core syllabuses for all branches of the anatomical sciences. This is being undertaken at the initial stage using Delphi Panels consisting of a team of anatomists, scientists and clinicians who evaluate syllabus content and accord each element/topic “essential”, “important”, “acceptable” or “not required” status. Their initial conjectures, published on the IFAA website, provide merely a framework to enable anatomical (and other cognate learned) societies and individual anatomists, clinicians and students to comment upon the syllabuses. Here is presented the concepts and methodological approaches underlying the hybrid Delphi process employed. Preliminary findings relating to the development of a neuroanatomy core syllabus are provided to illustrate the methods initially employed by a Delphi Panel. The approach is novel in that it is international in scope, is conceptually democratic, and is developmentally fluid in terms of availability for amendment. The aim is to set internationally recognized standards and thus to provide guidelines concerning anatomical knowledge when engaged in course development.

description: We study a particle propagation on a circle in the presence of a point interaction. We show that the one-particle Feynman kernel can be written into the sum of reflected and transmitted trajectories which are weighted by the elements of the n-th power of the scattering matrix evaluated on a line with a point interaction. As a by-product we find three-parameter family of trace formulae as a generalization of the Poisson summation formula.

Recollecting Wounded Narratives: The Reconstruction of a Backpack
Creators: name: Flohr, Zsuzsi
Publisher: name: Diffractions
Year: 2021

description: This photo essay examines the process of recollecting wounded narratives. It explores how these narratives are rooted in various concepts of memory and postmemory, which are, in turn, embedded in a familial framework and in the visual arts. The focus here is on a backpack formerly owned by my grandfather, Gyula Flohr, which was the inspiration for my art project Chances in Life – Grandpa’s Backpack. This project illustrates the process of recollecting wounded narratives in practice, addressing the life of my grandfather, primarily by reconstructing through drawings the built environment in which his life was framed, examining discovered family relics, and listening to conversations with Gyula’s two children: my father, János, and my aunt, Marcsi. Chances in Life presents contradictory narratives told by the family and the state, pointing to nuanced social and gender relations, and the diminished chances in life in Eastern Europe in an increasingly closed society.

description: In the application of potential models, the use of the Dirac equation in central potentials remains of phenomenological interest. The associated set of decoupled second-order ordinary differential equations is here studied by exploiting the phase-integral technique, following the work of Froman and Froman that provides a powerful tool in ordinary quantum mechanics. For various choices of the scalar and vector parts of the potential, the phase-integral formulae are derived and discussed, jointly with formulae for the evaluation of Stokes and anti-Stokes lines. A criterion for choosing the base function in the phase-integral method is also obtained, and tested numerically. The case of scalar confinement is then found to be more tractable.

Flavor-changing interactions with singlet quarks and their implications for the LHC

Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the flavor-changing interactions in an extension of the standard model with singlet quarks and singlet Higgs, which are induced by the mixing between the ordinary quarks and the singlet quarks ($ q $-$ Q $ mixing). We consider the effects of the gauge and scalar interactions in the $ ΔF = 2 $ mixings of $ K^0 $, $ B_d $, $ B_s $ and $ D^0 $ mesons to show the currently allowed range of the $ q $-$ Q $ mixing. Then, we investigate the new physics around the electroweak scale to the TeV scale, which is accessible to the Large Hadron Collider. Especially, the scalar coupling mediated by the singlet Higgs may provide distinct signatures for the decays of the singlet quarks and Higgs particles, which should be compared with the conventionally expected ones via the gauge and standard Higgs couplings. Observations of the singlet quarks and Higgs particles will present us important insights on the $ q $-$ Q $ mixing and Higgs mixing.

At the nucleus of the problem: the nuclear envelope and disease
Creators: name: Maraldi, Nadir M.
Publisher: name: Italian Journal of Anatomy and Embryology
Year: 2015

description: Le linkage of some 24 diseases to mutations in proteins of the nuclear envelope has stimulated a major reassessment of the function of the nuclear envelope, and particularly the nuclear lamina, as more than half of these diseases are caused by mutations of the LMNA gene, coding lamin A. As a consequence of these studies, we now envisage the nuclear envelope/lamina functioning not only as a molecular device regulating the transfer of macromolecules between the cytoplasm and the nucleus, but as a key cellular hub in integrating critical functions that include chromatin, organization, modulation of signaling pathways, and transcriptional regulation (1).
A fundamental issue in deciphering the molecular basis of the pathogenic mechanisms of laminopathies has been obtained demonstrating that these diseases are not due to a loss of function of lamin A but to a gain of function of immature forms of the protein, referred to as prelamin A, which are differently modified by posttranslational processes (2).
Here we review the involvement of defects of prelamin A processing in the pathogenesis of different classes of laminopathies, which include muscular, metabolic, and progeric laminopathies. In particular, we will focus on the pathogenic mechanism of the Hutchinson-Gilford progeric syndrome (HGPS), which involve a particular form of prelamin A, the progerin, whose accumulation in the nucleus affects both chromatin arrangement and transcriptional regulation. The identification of the molecular basis of progeric laminopathies contributed to the development of a targeted therapy on the experimental models of the disease (3).
In the last three years encouraging results have been also obtained by pharmacological trials on selected groups of progeric patients.
Since low levels of progerin are also accumulated in normal aging, particular attention has been given to differential expression of prelamin A forms in the cells of a particular class of healthy aged subjects, represented by centenarians (4).

Invented Histories: Gossip as Archival Practice in Anna Burns' Milkman
Creators: name: Wielechowski, Holly
Publisher: name: Diffractions
Year: 2021

description: In this article I will interrogate the role of gossip as archival practice as evidenced in Anna Burns’ 2018 novel Milkman. Set at the height of the Northern Irish Troubles, the novel depicts the complex power dynamics that are enacted within the Catholic community. The novel focuses intensely on gender, being a coming-of-age novel for the unnamed female narrator whose life is entirely structured by the power plays that enmesh her on a daily basis. I will argue that these complex power dynamics are maintained by the use of non-traditional forms of archiving – specifically gossip. Further, I will argue that the contemporaneous archival practices foregrounded in the novel delimit the potential for subjectivity to only two clear forms: what Michael Rothberg has termed the “implicated subject” and what Burns herself terms in the novel the “beyond-the-pales,” or those who have been effectively cast out of the Catholic community.

description: In this article I analyze two self-portraits by women artists that question art history’s power structures by citing canonical paintings by men from the discipline’s archive. In Self-portrait as Tahitian (1934) Hungarian-Indian woman artist Amrita Sher-Gil depicts her own half-nude body, while referencing the (in)famous Tahiti paintings by Paul Gauguin, underscoring the various complexities of the global trajectories of modernist artistic practice. The photograph Lady in Moonlight (2004) casts Pushpamala N. as the idealized lady of an 1898 Raja Ravi Varma oil painting. I argue that through a double bind position (Spivak) taken by the artists, Self-Portrait as Tahitian and Lady in Moonlight make gender visible in art history’s archive and display its structuring power in canonical logics. Through a citational move, the artists place themselves simultaneously in- and out-side art history, and posit not only the self as other, inherent to any self-portraiture, but also the Other as self.

description: Shaken baby syndrome (SBS) is the most common cause of death related to child abuse; nonfatal consequences of SBS include varying degrees of visual, motor and cognitive impairment due to severe brain damage in almost 30% of infants with SBS. Brain damage occurs from the biomechanical forces, swelling, ischemia and altered vascular autoregulation and from additionally axonal damage[1].In the present study we want to examine a cohort of 7 patient affected by SBS and compare their data with controls choosen by same range of age, 19 months till 60. Using MRI techniques we define a new paradigm for demonstrating, through voxel based morphometry, deficiencies, connected to white and grey matter regions, in the prefrontal cortex and also in the hippocampus, amygdala, corpus callosum and optical radiation. Adding diffusion tensor imaging technique by constrained spherical deconvolution[2] our study put in evidence connectivity between investigated areas, suggesting neural network abnormalities. With this “state of art” studies we can show a correlation between childhood abuse and brain structures modification. Our aim is to make a longitudinal study on the anatomical data of these patients following their clinical evolution.

description: The key role played by the stroma in breast cancer development and progression has been widely recognized.
Recently, we reported that the cross-talk between epithelial and stromal cells affects structural and functional features correlated with the invasive phenotype of breast cancer cells by co-culturing mammary cancer cells with different metastatic potential (MDA-MB-231>MCF-7) with fibroblasts isolated from breast healthy skin (normal fibroblasts, NFs) or breast tumor stroma (cancer-associated fibroblasts, CAFs) [1].
This study was designed to deepen the knowledge of the role played notably by CAFs in promoting breast tumor cell migratory skill through the analysis of the expression/activity of downstream potential target molecules and of the contribution of paracrine signalings.
Thus, we investigated the influence of fibroblasts on the expression of Stearoyl- CoA desaturase 1 (SCD1), the main enzyme regulating membrane fluidity, as well as on the level and activity of its transcription factor, SREBP1, in breast cancer cells. The ability of CAFs to promote a 2-3 fold increase in SCD1 mRNA and protein expression as well as an induction of SREBP1 DNA binding activity has been shown in the two cancer cell lines. Both siRNA-mediated and pharmacological inhibition of SCD1 impaired tumor cells migration. To clarify the possible role of tumor-stroma paracrine interaction in the previously reported improvement of cancer cell migratory ability, cocultures were set up in presence of neutralizing antibodies against hepatocyte growth factor, transforming growth factor-β or basic fibroblast growth factor. Cell tracking analysis demonstrated that the CAF-mediated increase in tumor cell migration speed was reduced or abolished by neutralizing the above soluble factors.
These results provide new insights in understanding the role of CAFs in promoting tumor cell invasiveness and may help to devise new targeted therapeutic approaches.

Un team guidato da astronomi italiani scopre che i grandi buchi neri al centro delle galassie possono, inaspettatamente, sia favorire la creazione di nuove stelle sia bloccarne la formazione. Per la prima volta entrambi gli effetti sono stati osservati nella stessa galassia. Un poker di studi scientifici condotti da astronomi dell’INAF e dell’Università di Bologna svela come i venti galattici scavino delle cavità nel gas interstellare, ai bordi delle quali si accendono nuove stelle

description: This paper presents our approach of the radio interface problematic for Wireless Sensor Network. We introduce the WSN context and constraints associated. We propose an IR-UWB solution and illustrate why it could be a viable solution for WSN. A high level modelling and simulation platform for IR-UWB radio interface is proposed on Matlab. It allows us to determine according to BER versus Eb/N0 criteria and the WSN constraints what kind of design is more adequate. Moreover, a co-design co-simulation platform Matlab VHDL is proposed here. Using this platform we designed IR-UWB transceiver having reconfigurable capabilities, such as data rate reconfiguration, time hopping code, spectrum occupation and radio range reconfiguration.

description: The phenomenon of spin resonance has had far reaching influence since its discovery nearly 70 years ago. Electron spin resonance (ESR) driven by high frequency magnetic fields has informed our understanding of quantum mechanics, and finds application in fields as diverse as medicine and quantum information. Spin resonance induced by high frequency electric fields, known as electric dipole spin resonance (EDSR), has also been demonstrated recently. EDSR is mediated by spin-orbit interaction (SOI), which couples the spin degree of freedom and the momentum vector. Here, we report the observation of a novel spin resonance due to SOI that does not require external driving fields. Ballistic spin resonance (BSR) is driven by an internal spin-orbit field that acts upon electrons bouncing at gigaHertz frequencies in narrow channels of ultra-clean two-dimensional electron gas (2DEG). BSR is manifested in electrical measurements of pure spin currents as a strong suppression of spin relaxation length when the motion of electrons is in resonance with spin precession. These findings point the way to gate-tunable coherent spin rotations in ballistic nanostructures without external a.c. fields.
