The (In)Visibility of Migrants
Authors: Massari Alice 
Published: May 2021

AbstractBruno Catalano’s sculpture Voyageurs brilliantly catches an impalpable, yet pervasive, feature of refugees’ representation: their invisibility. This may seem an oxymoron but throughout my visual analysis, and while looking for what was represented in the images studied, I have been struck by what is not there. Susan Sontag has defined photography as “grammar and, even more importantly, an ethics of seeing!” (Sontag 1973, 1). If Sontag is right when she affirms that photography makes things represented worth being seen, we may be led to think that, on the contrary, what is not photographed is not worth seeing. On this arbitrary decision over presence and absence, visibility and invisibility, hinges a very important dimension of the power of photography.
AdS3 gravity and the complex SYK models

Abstract
We provide a non-conformal generalization of the Compère-Song-Strominger (CSS) boundary conditions for AdS3 gravity that breaks the $$ \hat{u}(1) $$

Kac-Moody-Virasoro symmetry to two u(1)s. The holographic dual specified by the new boundary conditions can be understood as an irrelevant deformation of a warped conformal field theory (WCFT). Upon consistent reduction to two dimensions, AdS3 gravity results in a deformed Jackiw-Teitelboim dilaton gravity model coupled to a Maxwell field. We show that near extremality the boundary conditions inherited from generalized CSS boundary conditions in three dimensions give rise to an effective action exhibiting the same symmetry breaking pattern as the complex Sachdev-Ye-Kitaev models. Besides the Schwarzian term reflecting the breaking of conformal symmetry, the effective action contains an additional term that captures the breaking of the $$ \hat{u}(1) $$

A modified in-medium evolution equation with color coherence
Authors: Barata João , Domínguez Fabio , Salgado Carlos A. , Vila Víctor 
Published: May 2021

Abstract
QCD jets produced in heavy-ion collisions at LHC or RHIC energies partially evolve inside the produced hot and dense quark gluon plasma, offering unique opportunities to study QCD splitting processes in different backgrounds. Induced (modified) splittings are expected to be the most relevant mechanism driving the modifications of in-medium jets compared to vacuum jets for a wide sets of observables. Although color coherence among different emitters has been identified as an essential mechanism in studies of the QCD antenna radiation, it is usually neglected in the multi-gluon medium-induced cascade. This independent gluon emission approximation can be analytically proved to be valid in the limit of very large media, but corrections or modifications to it have not been computed before in the context of the evolution (or rate) equation describing the gluon cascade. We propose a modified evolution equation that includes corrections due to the interference of subsequent emitters. In order to do so, we first compute a modified splitting kernel following the usual procedure of factorizing it from the subsequent Brownian motion. The calculation is performed in the two-gluon configuration with no overlapping formation times, that is expected to provide the first correction to the completely independent picture.
Comments on gauge anomalies at dimension-six in the Standard Model Effective Field Theory
Authors: Bonnefoy Quentin , Di Luzio Luca , Grojean Christophe , Paul Ayan , Rossia Alejo N. 
Published: May 2021

Abstract
We study whether higher-dimensional operators in effective field theories, in particular in the Standard Model Effective Field Theory (SMEFT), can source gauge anomalies via the modification of the interactions involved in triangle diagrams. We find no evidence of such gauge anomalies at the level of dimension-6 operators that can therefore be chosen independently to each others without spoiling the consistency of SMEFT, at variance with recent claims. The underlying reason is that gauge-invariant combinations of Goldstone bosons and massive gauge fields are allowed to couple to matter currents which are not conserved. We show this in a toy model by computing the relevant triangle diagrams, as well as by working out Wess-Zumino terms in the bosonic EFT below all fermion masses. The same approach applies directly to the Standard Model both at the renormalisable level, providing a convenient and unusual way to check that the SM is anomaly free, as well as at the non-renormalisable level in SMEFT.
Chaotic string dynamics in deformed T1,1
Authors: Ishii Takaaki , Kushiro Shodai , Yoshida Kentaroh 
Published: May 2021

Abstract
Recently, Arutyunov, Bassi and Lacroix have shown that 2D non-linear sigma model with a deformed T1,1 background is classically integrable [arXiv:2010.05573 [hep-th]]. This background includes a Kalb-Ramond two-form with a critical value. Then the sigma model has been conjectured to be non-integrable when the two-form is off critical. We confirm this conjecure by explicitly presenting classical chaos. With a winding string ansatz, the system is reduced to a dynamical system described by a set of ordinary differential equations. Then we find classical chaos, which indicates non-integrability, by numerically computing Poincaré sections and Lyapunov spectra for some initial conditions.

AbstractWe determine the eigenvalues of certain “fundamental”K-invariant Toeplitz type operators on weighted Bergman spaces over bounded symmetric domains$$D=G/K,$$D=G/K,for the irreducibleK-types indexed by all partitions of length$$r={\mathrm {rank}}(D)$$r=rank(D).
On the 2D Ericksen–Leslie equations with anisotropic energy and external forces
Authors: Brzeźniak Zdzislaw , Deugoué Gabriel , Razafimandimby Paul André 
Published: May 2021

AbstractIn this paper we consider the 2D Ericksen–Leslie equations which describe the hydrodynamics of nematic liquid crystal with external body forces and anisotropic energy modeling the energy of applied external control such as magnetic or electric field. Under general assumptions on the initial data, the external data and the anisotropic energy, we prove the existence and uniqueness of global weak solutions with finitely many singular times. If the initial data and the external forces are sufficiently small, then we establish that the global weak solution does not have any singular times and is regular as long as the data are regular.
Lenalidomide enhances the efficacy of anti-BCMA CAR-T treatment in relapsed/refractory multiple myeloma: a case report and revies of the literature

Published: May 2021

AbstractWe report successful clinical experience using anti-BCMA CAR-T combined with lenalidomide in a patient who was refractory to a previous CAR-T treatment. The patient was a 51-year-old man, and was diagnosed with IgD-λ multiple myeloma(MM) in October 2015. 10 courses of chemotherapy including immunomodulators and proteasome inhibitors were used for remission and autologous hematopoietic stem cell transplantation was performed. MM relapsed after 12 months of remission. His disease continued to progress after multiple chemotherapy regimens, mouse anti-BCMA CAR-T and human-derived anti-BCMA CAR-T therapy. After a conditioning chemotherapy regimen of fludarabine and cyclophosphamide, patient took lenalidomide on day -1 and human-derived anti-BCMA CAR-T cells were infused on the next day. He suffered grade 2 cytokine-releasing syndrome(CRS) and grade 3 myelosuppression after infusion, and were resolved after symptomatic treatment. Very good partial response (VGPR) was achieved 14 days after CAR-T treatment, and had been maintained for more than 8 months. We demonstrated for the first time in patients that anti-BCMA CAR-T cell therapy combined with lenalidomide is feasible and effective in the treatment of RRMM. It provides a new strategy for RRMM patients who do not respond to anti-BCMA CAR-T cell therapy alone, and the adverse event is reversible.

AbstractDue to the complex relationship between pollen and vegetation, it is not yet clear how pollen diagrams may be interpreted with respect to changes in floristic diversity and only a few studies have hitherto investigated this problem. We compare pollen assemblages from moss samples in two southeastern European forests with the surrounding vegetation to investigate (a) their compositional similarity, (b) the association between their diversity characteristics in both terms of richness and evenness, and (c) the correspondence of the main ecological gradients that can be revealed by them. Two biogeographical regions with different vegetation characteristics, the Pieria mountains (north central Greece) and the slopes of Ciomadul volcano (eastern Romania), were chosen as divergent examples of floristic regions, vegetation structure and landscape openness. Pollen assemblages are efficient in capturing the presence or absence, rather than the abundance in distribution of plants in the surrounding area and this bias increases along with landscape openness and vegetation diversity, which is higher in the Pieria mountains. Pollen assemblages and vegetation correlate better in terms of richness, that is, low order diversity indices. Relatively high correlation, in terms of evenness, could be potentially found in homogenous and species poor ecosystems as for Ciomadul. Composition and diversity of woody, rather than herb, vegetation is better reflected in pollen assemblages of both areas, especially for Pieria where a direct comparison of the two components was feasible, although this depends on the species-specific pollen production and dispersal, the openness of landscape and the overall diversity of vegetation. Gradients revealed by pollen assemblages are highly and significantly correlated with those existing in vegetation. Pollen assemblages may represent the vegetation well in terms of composition, diversity (mainly richness) and ecological gradients, but this potential depends on land use, vegetation structure, biogeographical factors and plant life forms.

Zusammenfassung
Einleitung
Jährlich stellen sich bundesweit zahlreiche Patienten in zentralen Notaufnahmen vor. Ziel der vorliegenden Untersuchung war es, alters- und geschlechtsabhängig Zuführung, Ersteinschätzung, Entlassart und Verweildauer an einem universitären Standort zu analysieren.

Material und Methodik
In dieser retrospektiven Studie wurden alle Patientenkontakte der zentralen Notaufnahme des Universitätsklinikums Düsseldorf des Jahres 2019 erfasst und anhand der Prozesskriterien Zuführung, Ersteinschätzung, Entlassart und Verweildauer kategorisiert und deren Verteilung untersucht.

Ergebnisse
Vom 01.01. bis 31.12.2019 wurden insgesamt 43.821 Patientenkontakte erfasst. Das durchschnittliche Alter der Patienten betrug 47 ± 24 Jahre (Median: 47, Min.–Max.: 0–106). Der Anteil weiblicher Patienten betrug 48 %. Ein Alter ≤ 17 Jahren wiesen 10 % der Patienten (♀ vs. ♂: 4 vs. 6 %, p < 0,0001) und ein Alter ≥ 70 Jahre 24 % auf (♀ vs. ♂: 13 vs. 11 %, p < 0,0001). Für beide Geschlechter nahm der Anteil der Triagekategorien „blau“ und „grün“ über die aufsteigenden Altersgruppen stetig ab. Ab der Altersgruppe der 50- bis 59-Jährigen lag für beide Geschlechter führend eine höhere Dringlichkeit („gelb“ bis „rot“) vor. Während im Alter ≤ 17 Jahren mit 84–90 % vorwiegend eine ambulante Behandlung erfolgte, reduzierte sich dieser Anteil über die weiteren Altersgruppen bis auf 22 % bei Männern und 28 % bei Frauen in der Altersgruppe der ≥ 90-Jährigen. Für die drei Entlassarten „ambulant“, „prästationär“ und „stationär“ stieg die Verweildauer bei beiden Geschlechtern mit dem Alter kontinuierlich an.

Schlussfolgerung
Es finden sich deutliche und vor allem altersabhängige Unterschiede in den Prozesskriterien Zuführung, Ersteinschätzung, Entlassart und Verweildauer. Rund 15 % der Patienten sind kritisch krank oder verletzt („orange“ und „rot“). Mit steigendem Alter nimmt der Anteil dieser Triagekategorien zu. Bei rund 30 % der Patienten besteht eine stationäre Aufnahmeindikation, entsprechende Bettenkapazitäten müssen täglich eingeplant werden.

AbstractIn patients with repaired Tetralogy of Fallot (ToF), detailed assessment of right ventricular (RV) function is important for management and timing of possible pulmonary valve re-intervention. The aim of this study was to evaluate RV function using two-dimensional multi-plane echocardiography (2D MPE), a novel four-wall imaging method obtained from one apical acoustic window utilising electronic plane rotation. In sixty-two ToF patients (aged - 28 [22, 39] years, 65% male), systolic function of four different RV walls (lateral, anterior, inferior and inferior coronal) were evaluated using MPE. Tricuspid annular plane systolic excursion (TAPSE), tricuspid annular peak systolic velocity (RV-S′) and RV wall longitudinal strain (RV-LS) measurements were compared with those of matched healthy individuals. 2D MPE measurements were highly feasible across the four RV walls (93.5–100% for TAPSE/S′; 66.1–95.1% for RVLS) and could be performed more reliably than 3D RV ejection fraction (RVEF − 56.5%). All functional values were significantly reduced when compared to the control group (p < 0.001). Higher RV-LS values were seen in the lateral (− 17.8 ± 4.5%) and inferior (− 17.8 ± 4.2%) walls compared to the anterior (− 15.9 ± 3.8%) and inferior coronal (− 15.1 ± 3.9%) walls. 3D RVEF correlated strongest with RV-LS values from the lateral (r − 0.50; p = 0.002) and anterior walls (r − 0.74; p < 0.001) and furthermore the four-wall average (r − 0.57; p = 0.001). 2D MPE evaluation of the RV is highly feasible in ToF patients. This novel method provides new insights into regional RV wall function, enabling a more comprehensive and quantitative approach to RV assessment in daily clinical practice.
Kettle Logic

Published: May 2021

AbstractThis article unearths the political logic of the police kettle. Rather than add to the mundane debate about civil liberties or models of policing, this article argues that the kettle reveals nothing less than the police war at the heart of modernity. This is a police war carried out as a logic of containment against the enemy within—within the kettle and within society. The kettle is a microcosm of the police war of containment.
Recurrence-mediated suprathreshold stochastic resonance
Authors: Knoll Gregory , Lindner Benjamin 
Published: May 2021

AbstractIt has previously been shown that the encoding of time-dependent signals by feedforward networks (FFNs) of processing units exhibits suprathreshold stochastic resonance (SSR), which is an optimal signal transmission for a finite level of independent, individual stochasticity in the single units. In this study, a recurrent spiking network is simulated to demonstrate that SSR can be also caused by network noise in place of intrinsic noise. The level of autonomously generated fluctuations in the network can be controlled by the strength of synapses, and hence the coding fraction (our measure of information transmission) exhibits a maximum as a function of the synaptic coupling strength. The presence of a coding peak at an optimal coupling strength is robust over a wide range of individual, network, and signal parameters, although the optimal strength and peak magnitude depend on the parameter being varied. We also perform control experiments with an FFN illustrating that the optimized coding fraction is due to the change in noise level and not from other effects entailed when changing the coupling strength. These results also indicate that the non-white (temporally correlated) network noise in general provides an extra boost to encoding performance compared to the FFN driven by intrinsic white noise fluctuations.
Flexible zinc oxide photoelectrode for photo electrochemical energy conversion

Published: May 2021

AbstractPhotoelectrochemical properties have been investigated for flexible photoelectrodes containing 310 nm thick ZnO film on spin-coated ITO/PET. The high crystalline structure of ZnO was studied using x-ray diffraction pattern. A value of 3.4 eV has been estimated for optical band gap from its absorption spectra. The flexible ZnO photoelectrode was demonstrated to generate photoelectrochemical current. The photocurrents are enhanced by 4% whereas flat-band potential is shifted by 8 V due to the illumination. Values of 1.022 and 0.714 AW−1 were found to be for photo switching and photoresponsivity, respectively. ZnO/ITO/PET can be used as a substrate for making flexible hybrid PEC devices to generate solar power and solar fuels.
Care of Children with DiGeorge Before and After Cultured Thymus Tissue Implantation
Authors: Gupton Stephanie E. , McCarthy Elizabeth A. , Markert M. Louise 
Published: May 2021

Abstract
Background
Children with complete DiGeorge anomaly (cDGA) have congenital athymia plus a myriad of other challenging clinical conditions. The term cDGA encompasses children with congenital athymia secondary to 22q11.2DS, CHARGE syndrome (coloboma, heart defects, choanal atresia, growth or mental retardation, genital abnormalities, and ear abnormalities and/or deafness), and other genetic abnormalities. Some children have no known genetic defects. Since 1993, more than 100 children with congenital athymia have been treated with cultured thymus tissue implantation (CTTI). Naïve T cells develop approximately 6 to 12 months after CTTI. Most of the children had significant comorbidities such as heart disease, hypoparathyroidism, and infections requiring complex clinical care post cultured thymus tissue implantation (CTTI).

Objective
The purpose of this guidance is to assist multidisciplinary teams in caring for children with cDGA both before and after CTTI.

Methods
Thirty-one specialists, in addition to the authors, were asked to share their experience in caring for children with cDGA at Duke University Health System, before and after CTTI. These specialists included physicians, nurses, dentists, therapists, and dieticians.

Results
The goal of a multidisciplinary approach is to have children in the best possible condition for receiving CTTI and provide optimal care post CTTI through development of naïve T cells and beyond. The CTT (cultured thymus tissue) must be protected from high doses of steroids which can damage CTT. Organs must be protected from adverse effects of immunosuppression.

Conclusion
Creating a multidisciplinary team and a detailed plan of care for children with cDGA is important for optimal outcomes.
Assessing the Role of Developmental and Environmental Factors in Chemical Defence Variation in Heliconiini Butterflies

Published: May 2021

AbstractChemical defences in animals are both incredibly widespread and highly diverse. Yet despite the important role they play in mediating interactions between predators and prey, extensive differences in the amounts and types of chemical compounds can exist between individuals, even within species and populations. Here we investigate the potential role of environment and development on the chemical defences of warningly coloured butterfly species from the tribe Heliconiini, which can both synthesize and sequester cyanogenic glycosides (CGs). We reared 5 Heliconiini species in captivity, each on a single species-specific host plant as larvae, and compared them to individuals collected in the wild to ascertain whether the variation in CG content observed in the field might be the result of differences in host plant availability. Three of these species were reared as larvae on the same host plant,Passiflora riparia, to further test how species, sex, and age affected the type and amount of different defensive CGs, and how they affected the ratio of synthesized to sequestered compounds. Then, focusing on the generalist speciesHeliconius numata, we specifically explored variation in chemical profiles as a result of the host plant consumed by caterpillars and their brood line, using rearing experiments carried out on two naturally co-occurring host plants with differing CG profiles. Our results show significant differences in both the amount of synthesized and sequestered compounds between butterflies reared in captivity and those collected in the field. We also found a significant effect of species and an effect of sex in some, but not all, species. We show that chemical defences inH. numatacontinue to increase throughout their life, likely because of continued biosynthesis, and we suggest that variation in the amount of synthesized CGs in this species does not appear to stem from larval host plants, although this warrants further study. Interestingly, we detected a significant effect of brood lines, consistent with heritability influencing CG concentrations inH. numata. Altogether, our results point to multiple factors resulting in chemical defence variation in Heliconiini butterflies and highlight the overlooked effect of synthesis capabilities, which may be genetically determined to some extent.
