description: We retrospectively compared the therapeutic effects of combination therapy with prednisolone (PSL) and oral tacrolimus (TAC) or azathioprine (AZA) on progressive interstitial pneumonia with systemic sclerosis (SSc-PIP). The effects of PSL (0.2–0.5 mg/kg/day) and TAC (3 mg/day) or AZA (1–2 mg/kg/day) therapies (n = 18) were evaluated for short (12 months) and long (36 months or more) periods. In the short period, IP improved in 6 and 5 patients and was stable in 12 and 13 patients in the TAC and AZA groups, respectively. In the long period, 11 patients were followed up in the TAC group and 12 in the AZA group. IP improved in 4 and 2 patients and was stable in seven and nine in the TAC and AZA groups, respectively. The rates of evolution of total fibrosis score, and those corrected by disease duration for the long period, in the TAC group were significantly lower than those in the AZA group (p = .017 and .025, respectively). The inhibitory effect of PSL and TAC combination therapy on the progression of fibrosis in SSc-PIP may be superior to that of PSL and AZA in the long period.

description: NGC 6441 is a bulge globular cluster with an unusual horizontal branch morphology and a rich population of RR Lyrae (RRL) and Type II Cepheid (T2C) variables that is unexpected for its relatively high metallicity. We present near-infrared (NIR, $JHK_s$) time-series observations of 42 RRL, 8 T2Cs, and 10 eclipsing binary candidate variables in NGC 6441. The multi-epoch observations were obtained using the FLAMINGOS-2 instrument on the 8-m Gemini South telescope. Multi-band data are used to investigate pulsation properties of RRL and T2C variables including their light curves, instability strip, period--amplitude diagrams, and period--luminosity and period--wesenheit relations (PLRs and PWRs) in $JHK_s$ filters. NIR pulsation properties of RRL variables are well fitted with theoretical models that have canonical helium content and mean-metallicity of NGC 6441 ([Fe/H]$=-0.44\pm0.07$~dex). The helium-enhanced RRL models predict brighter NIR magnitudes and bluer colors than the observations of RRL in the cluster. This suggests that these RRL variables in NGC 6441 are either not significantly helium enhanced as previously thought or the impact of such enhancement is smaller in NIR than the predictions of the pulsation models. We also use theoretical calibrations of RRL period--luminosity--metallicity (PLZ) relations to simultaneously estimate the mean reddening, $E(J-K_s)=0.26\pm0.06$~mag, and the distance, $d=12.67\pm0.09$~kpc, to NGC 6441. Our mean reddening value and the distance are consistent with the independent estimates from the bulge reddening map based on red clump stars and the latest Gaia data, respectively. Our distance and reddening values provide a very good agreement between the PLRs of T2Cs in NGC 6441 and those for RRL and T2Cs in Galactic globular clusters that span a broad range of metallicity.

description: We present the analysis of three more planets from the KMTNet 2021 microlensing season. KMT-2021-BLG-0119Lb is a $\sim 6\, M_{\rm Jup}$ planet orbiting an early M-dwarf or a K-dwarf, KMT-2021-BLG-0192Lb is a $\sim 2\, M_{\rm Nep}$ planet orbiting an M-dwarf, and KMT-2021-BLG-0192Lb is a $\sim 1.25\, M_{\rm Nep}$ planet orbiting a very--low-mass M dwarf or a brown dwarf. These by-eye planet detections provide an important comparison sample to the sample selected with the AnomalyFinder algorithm, and in particular, KMT-2021-BLG-2294, is a case of a planet detected by-eye but not by-algorithm. KMT-2021-BLG-2294Lb is part of a population of microlensing planets around very-low-mass host stars that spans the full range of planet masses, in contrast to the planet population at $\lesssim 0.1\, $ au, which shows a strong preference for small planets.

title: Characterization of radiation-hard monolithic CMOS sensors
Creators: name: Argemí, Lluís Simón
Publisher: name: University of Glasgow
Year: 2021

description: The work presented in this thesis consists of the characterisation of monolithic CMOS sensors targeting the requirements of the outer-most layer of the ATLAS Inner Tracker after the High Luminosity upgrade of the Large Hadron Collider. Three detectors are investigated: an investigator chip and two large scale demonstrators (MALTA and mini-MALTA). The investigator chip is designed in the standard TowerJazz 180 nm technology and served as a tool to investigate the geometric parameters that affect the pixel capacitance. The MALTA chip is designed in the modified TowerJazz 180 nm technology and implements a novel asynchronous readout to minimise power consumption. The sensor is irradiated with X-rays up to 1.25 MRad to test the resistance of the front-end circuit to ionising radiation effects. The mini-MALTA chip is designed following the results obtained on MALTA and implements an improved front-end and pixel layout to enhance the radiation hardness of MALTA. A similar X-ray irradiation campaign is done for this chip showing good radiation hardness after 80 MRad of TID. Aside from the characterisation work, FPGA-based readouts for the MALTA and mini-MALTA chips were developed in collaboration with the CMOS development group at CERN.
The LPM effect in sequential bremsstrahlung: incorporation of "instantaneous'' interactions for QCD

description: The splitting processes of bremsstrahlung and pair production in a medium are coherent over large distances in the very high energy limit, which leads to a suppression known as the Landau-Pomeranchuk-Migdal (LPM) effect. We continue study of the case when the coherence lengths (formation lengths) of two consecutive splitting processes overlap, avoiding soft-emission approximations. Previous work made a ``nearly-complete'' calculation of the effect of overlapping formation times on gluonic splittings such as $g \to gg \to ggg$ (with simplifying assumptions such as an infinite QCD medium and the large-$N_c$ limit). In this paper, we extend those previous rate calculations from nearly-complete to complete by including processes involving the exchange of longitudinally-polarized gluons. In the context of Lightcone Pertubation Theory, used earlier for the ``nearly-complete'' calculation, such exchanges are instantaneous in lightcone time and have their own diagrammatic representation.

description: We present a catalog of continuum and emission line properties for 750,414 broad-line quasars included in the Sloan Digital Sky Survey Data Release 16 quasar catalog (DR16Q), measured from optical spectroscopy. These quasars cover broad ranges in redshift ($0.1\lesssim z\lesssim 6$) and luminosity ($44\lesssim \log (L_{\rm bol}/{\rm erg\,s^{-1}})\lesssim 48$), and probe lower luminosities than an earlier compilation of SDSS DR7 quasars. Derived physical quantities such as single-epoch virial black hole masses and bolometric luminosities are also included in this catalog. We present improved systemic redshifts and realistic redshift uncertainties for DR16Q quasars using the measured line peaks and correcting for velocity shifts of various lines with respect to the systemic velocity. About 1%, 1.4%, and 11% of the original DR16Q redshifts deviate from the systemic redshifts by $|ΔV|>1500\,{\rm km\,s^{-1}}$, $|ΔV|\in [1000,1500]\,{\rm km\,s^{-1}}$, and $|ΔV|\in [500,1000]\,{\rm km\,s^{-1}}$, respectively; about $1900$ DR16Q redshifts were catastrophically wrong ($|ΔV|>10,000\,{\rm km\,s^{-1}}$). We demonstrate the utility of this data product in quantifying the spectral diversity and correlations among physical properties of quasars with large statistical samples.

description: This chapter discusses the need of security and privacy protection mechanisms in aggregation protocols used in wireless sensor networks (WSN). It presents a comprehensive state of the art discussion on the various privacy protection mechanisms used in WSNs and particularly focuses on the CPDA protocols proposed by He et al. (INFOCOM 2007). It identifies a security vulnerability in the CPDA protocol and proposes a mechanism to plug that vulnerability. To demonstrate the need of security in aggregation process, the chapter further presents various threats in WSN aggregation mechanisms. A large number of existing protocols for secure aggregation in WSN are discussed briefly and a protocol is proposed for secure aggregation which can detect false data injected by malicious nodes in a WSN. The performance of the protocol is also presented. The chapter concludes while highlighting some future directions of research in secure data aggregation in WSNs.

description: We compute the effect of rigid rotation on the non-relativistic bound states. The energy levels of the bound states increase with the angular velocity of rotation until at certain value of the angular velocity they are completely pushed out into the continuum which corresponds to dissociation of the bound states. When the angular velocity exceeds the critical value at which the ground state disappears into the continuum, no bound state is possible. This effect should have important consequences for the phenomenology of the quark-gluon plasma. One of the ways to study it experimentally is to observe the electromagnetic radiation emitted by a rotating bound state. We compute the corresponding intensity of electromagnetic radiation and show that it strongly depends on the angular velocity of rotation.

description: The infinite projected entangled simplex state (iPESS), a type of tensor network (TN) state, has been used successfully for simulating and characterizing {\it non-chiral} spin liquids on the kagome lattice. Here, we demonstrate that iPESS also provides a faithful representation of a {\it chiral} spin liquid (CSL) on the same lattice, namely the ground state of the spin-$1/2$ kagome Heisenberg antiferromagnet with a scalar chirality. By classifying local tensors according to SU$(2)$ and point group symmetries, we construct a chiral ansatz breaking reflection $P$ and time reversal $T$ symmetries while preserving $PT$. The variational TN states are shown to host, for bond dimension $D\ge 8$, a chiral gapless entanglement spectrum following SU$(2)_1$ conformal field theory. The correlation function shows a small weight long-range tail complying with the prediction of the TN bulk-edge correspondence. %{\color{red}With more constraints included, the chiral ansatz is reduced to a non-chiral one which preserves full point group symmetries due to an emergent {\it tensor conservation law} and is of relevance to the ground state at the Heisenberg point. Lastly, by simulations in the complete ansatz family we discuss the transition from the non-chiral spin liquid to the CSL induced by the scalar chirality term.} We identify a non-chiral manifold spanned by only a subset of symmetric tensors where a new emergent {\it tensor conservation law} is realized. This allows us to both probe the stability of the non-chiral spin liquid and discuss its transition to CSL induced by a scalar chirality term.

description: We investigate the effective potential of the Polyakov loop, which is the order parameter for the deconfinement phase transition in finite temperature QCD. Our work is based on the Hamiltonian approach in Coulomb gauge where finite temperature $T$ is introduced by compactifying one space direction. We briefly review this approach and extend earlier work in the Yang-Mills sector by including dynamical quarks. In a first approximation, we follow the usual functional approach and include only one-loop contributions to the energy, with the finite temperature propagators replaced by their $T=0$ counter parts. It is found that this gives a poor description of the phase transition, in particular for the case of full QCD with $N_f = 3$ light flavours. The physical reasons for this unexpected result are discussed, and pinned down to a relative weakness of gluon confinement compared to the deconfining tendency of the quarks. We attempt to overcome this issue by including the relevant gluon contributions from the two-loop terms to the energy. We find that the two-loop corrections have indeed a tendency to strengthen the gluon confinement and weaken the unphysical effects in the confining phase, while slightly increasing the (pseudo-)critical temperature $T^\ast$ at the same time. To fully suppress artifacts in the confining phase, we must tune the parameters to rather large values, increasing the critical temperature to $T^\ast \approx 340\,\mathrm{MeV}$ for $G=SU(2)$.

description: We elucidate the existing controversies in the newly discovered K-doped iron selenide (KxFe2-ySe2-z) superconductors. The stoichiometric KFe2Se2 with \surd2\times\surd2 charge ordering was identified as the parent compound of KxFe2-ySe2-z superconductor using scanning tunneling microscopy and spectroscopy. The superconductivity is induced in KFe2Se2 by either Se vacancies or interacting with the anti-ferromagnetic K2Fe4Se5 compound. Totally four phases were found to exist in KxFe2-ySe2-z: parent compound KFe2Se2, superconducting KFe2Se2 with \surd2\times\surd5 charge ordering, superconducting KFe2Se2-z with Se vacancies and insulating K2Fe4Se5 with \surd5\times\surd5 Fe vacancy order. The phase separation takes place at the mesoscopic scale under standard molecular beam epitaxy condition.
Chorus and Chorality in Early Modern English Drama
Creators: name: Bigliazzi, Silvia
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2015

description: The essay offers a discussion of the progressive divergence, in early modern English drama, of the dramatic function of the chorus from the plural and lyrical performance derived from ancient theatre. Through an analysis of the gradual reduction in number of the performers and the chorus’s conflation with prologic and other framing texts in a time span of about fifty years, the essay retraces the gradual steps of the chorus’s transformation into an increasingly meta-theatrical piece, depriving the play of an element of lyrical artificiality traditionally attached to it. By showing that this theatrical device does have a history of its own in the English theatre, the essay argues that the loss of its traditional features, which allowed drama to provide a collective and lyrical response to the action enacted on stage, is occasionally made up for by a new and challenging idea of polyphonic chorality dislocated to other dramatic portions. Romeo and Juliet, in particular, is examined as an early example of this new choral experience, balancing the meta-theatrical dimension of a lyrico-narrative solo-performance of the Chorus, strategically appended to the play as a narrative voice competitive with the representational potential of (lyrical) drama.

This new annotated translation wishes to fill in the gap of a philologically and textually oriented interpretation of this complex text, testifying to its unextinguished relevance to the history of modern criticism on the Greek tragedy. The translation is complemented by textual notes on Schiller’s style and the historical context in which the piece was produced, as well as by a preface introducing the text to contemporary readers.

description: Ultra-Diffuse Galaxies are both extreme products of galaxy evolution and extreme environments in which to test our understanding of star formation. In this work, we contrast the spatially resolved star formation activity of a sample of 22 HI-selected UDGs and 35 low-mass galaxies from the NASA Sloan Atlas (NSA) within 120 Mpc. We employ a new joint SED fitting method to compute star formation rate and stellar mass surface density maps that leverage the high spatial resolution optical imaging data of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) and the UV coverage of GALEX, along with HI radial profiles estimated from a subset of galaxies that have spatially resolved HI maps. We find that the UDGs have low star formation efficiencies as a function of their atomic gas down to scales of 500 pc. We additionally find that the stellar mass-weighted sizes of our UDG sample are unremarkable when considered as a function of their HI mass -- their stellar sizes are comparable to the NSA dwarfs at fixed HI mass. This is a natural result in the picture where UDGs are forming stars normally, but at low efficiencies. We compare our results to predictions from contemporary models of galaxy formation, and find in particular that our observations are difficult to reproduce in models where UDGs undergo stellar expansion due to vigorous star formation feedback should bursty star formation be required down to $z=0$.

Men or Animals? Metamorphoses and Regressions of Comic Attic Choruses: the Case of Aristophanes's Wealth
Creators: name: Imperio, Olimpia

Year: 2015

description: This article starts from a reconsideration of the different theories that, since the last decades of the nineteenth century onwards, have discussed the issue of origins of the animal choruses disseminated in the comic Attic production of the fifth and fourth century BC. Nonetheless, it refrains from advancing solutions to a question which is destined to remain open, as well as from scrutinizing the more significant peculiarities of the choruses from the surviving and fragmentary plays by Aristophanes and other comedians of archaia and mese. It focuses instead on a particular case, the parodos of Wealth (Plutus), the last surviving comedy by Aristophanes, where a human chorus of old farmers temporarily regresses to a grotesquely wild animal state: a phenomenon which carries interesting implications for the metamorphic potentialities shown by an Attic comic chorus in an age of transition from archaia to mese.

Of Men and Ghosts: Delmore Schwartz’s Re-visitation of the Greek Chorus
Creators: name: Calanchi, Alessandra
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2015

description: Among the many elements of interest we encounter in Delmore Schwartz’s literary production, the re-visitation of the Greek chorus is particularly relevant. Its innovatory appeal, in fact, never ignores the call of tradition, and is rooted in the main issues of American culture, from immigration and problematic assimilation to the rise of consumer society and mass media. Through the presence of various versions of the chorus, which is alternatively composed of men, ghosts, angels, or even mere voices, and shifting from drama to poetry and vice-versa, the contemporary reader can get an extraordinary focus on the literary, psychological, and social background of the period spanning from the 1930s to the 1950s, while reconsidering the meaning of the chorus from different perspectives in the light of Schwartz’s prophetic insight into the deep changes the new millennium was going to bring about in such fields as communication, consciousness, identity, and collectivity.

description: The linear and the nonlinear non-Markovian quantum state diffusion equation (NMQSD) are well known tools for the description of certain non-Markovian open quantum systems. In this work, we systematically investigate whether the normalized linear NMQSD or the nonlinear NMQSD solutions can be generated by means of a time-continuous measurement. By considering any conceivable measurement scheme in the framework of instruments, we derive a necessary criterion for a measurement interpretation of both equations. Concrete examples show that the normalized linear NMQSD solutions are realizable only in the Markovian limit in general. The application of the presented criterion to the nonlinear NMQSD remains an open issue.

“Sordid particulars”: Deixis in the Chorus of Murder in the Cathedral
Creators: name: Marchesi, Maria Serena
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2015

description: Much has been written about the ritual function of the Chorus in T.S. Eliot’s Murder in the Cathedral. Eliot’s masterful handling of the rhythm and the ritual is undeniable, yet there is always more than meets the eye in Old Possum’s works. Eliot himself stated that the Chorus’s role is that of mediating “between the action and the audience”. Traditionally this comment has been read as an invitation to the audience to participate in the ritual as if they were, to all purposes, a congregation. This is only partly true. This paper aims to demonstrate that Eliot, through the – partly Shakespearean – use of deixis in the Chorus’s speeches, involves the audience not merely in the ritual slaughter of the martyr Thomas, but also, powerfully, in the horrors of history. The terror and revulsion associated with history, in fact, are expressed through Eliot’s thoroughly modernistic handling of the sordid, his well-stocked misogynistic repertoire and his references to recent murders as his most powerful tools to express the loathsome, unbearable burden of “very much reality”.

description: Abridged. We aim to better characterise the evolution and fates, and determine updated nucleosynthetic yields of intermediate-mass stars between primordial and EMP metallicity (Z=1e-10, 1e-8, 1e-7, 1e-6 and 1e-5). We also probed uncertainties in the nucleosynthesis of the oldest intermediate-mass stars during the asymptotic giant branch (AGB) phase. We analysed the evolution of models from their main sequence, through the thermally pulsing AGB (TP-AGB), to the latest stages of their evolution, using the Monash-Mount Stromlo stellar evolution code MONSTAR. The results were post-processed with the code MONSOON, which allowed for the determination of the nucleosynthetic yields of 77 species up to 62Ni. As reported in former works, we identified proton ingestion episodes (PIEs) in our lowest-mass lowest-Z models. Models of Z=1e-10 and Z=1e-8 in a narrow initial mass range around 5 Msun experience the cessation of thermal pulses, and their final fates as type-I1/2 supernovae cannot be discarded. All the models of initial mass of about 6-7 Msun experience a corrosive second dredge-up and undergo significant metal enrichment in their envelopes. This allows them to develop a solar-like TP-AGB or TP-super-AGB, ultimately becoming white dwarfs. Except for those undergoing the cessation of thermal pulses, all of our models show the nucleosynthetic signatures of both efficient third dredge-up and hot-bottom burning, with the activation of the NeNa cycle and the MgAlSi chains. This leads to the creation of vast amounts of CNO, with typical [N/Fe] > 4), and the characteristic abundance signature [N/Fe] > [C/Fe] > [O/Fe]. Due to differences in input physics (mostly related to convection and convective boundaries), our nucleosynthetic yields present dramatic differences with respect to recent results existing in the literature for intermediate-mass models of similar metallicities.

Harold Pinter’s Early Revue Sketches
Creators: name: Taylor-Batty, Mark
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2015

description: Considering Pinter’s early revue sketches as integral elements of his early writing project, this article puts them in partial dialogue with the longer dramatic works from his pen in the same period. The value and impact of his sketches is placed in the context of the playwright’s emerging career as a writer, and the contribution to his reputation they effected offers a suitable counterpoint to the mainstream view of his work as difficult or obscure. His choice of comedic theme and form in the sketches cannot simply be explained as his employing short-form to experiment with material he might expand or develop in his longer dramatic works, but the brevity of expression is clearly structured and exploited to offer a focussed delivery toward a revelation or punch-line, to such a degree that the journey to the punch-line often has greater dramatic importance than that final release. The use of phatic speech, audience confusion or mis-direction, allows Pinter to foreground character and index character motivation to forge humour from unexpected verbal developments. Vignettes that consider social power relationships are clearly important in these sketches and, while there is little that is overtly political, class structures and the relationship between power (including gendered power) and morality are explored across the portfolio of early sketches.

description: The classical problem of indentation on an elastic substrate has found new applications in the field of the Atomic Force Microscopy. However, linearly elastic indentation models are not sufficiently accurate to predict the force-displacement relationship at large indentation depths. For hyperelastic materials, such as soft polymers and biomaterials, a nonlinear indentation model is needed. In this paper, we use second-order elasticity theory to capture larger amplitude deformations and material nonlinearity. We provide a general solution for the contact problem for deformations that are second-order in indentation amplitude with arbitrary indenter profiles. Moreover, we derive analytical solutions by using either parabolic or quartic surfaces to mimic a spherical indenter. The analytical prediction for a quartic surface agrees well with finite element simulations using a spherical indenter for indentation depths on the order of the indenter radius. In particular, the relative error between the two approaches is less than 1% for an indentation depth equal to the indenter radius, an order of magnitude less than that observed with models which are either first-order in indentation amplitude or those which are second-order in indentation amplitude but with a parabolic indenter profile.
The Frame Story in Robert Browning’s Balaustion’s Adventure
Creators: name: Rossi Linguanti, Elena
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2016

description: This essay examines the way in which narrative diegesis and dramatic mimesis interact in Browning’s Balaustion’s Adventure, Including a Transcript from Euripides, a long poem in blank verse made of 2705 lines. The complex structure of this poem may be divided into four main sections: 1) an opening narrative frame, where Balaustion tells her four friends how she saved herself by reciting Euripides’ Alcestis at Syracuse; 2) the full version of Alcestis, which is not only recited by Balaustion but also commented upon; 3) a personal version accompanied by a new interpretation of the play; 4) a closing narrative frame, where Balaustion affirms Alcestis’ extraordinary value. In particular, the essay focuses on the frame with the aim of exploring the structural originality of the poem and its hybrid texture: with regard to the literary genre, the frame blends drama, historical narratives and epics; as for the mode, mimesis and diegesis alternate in almost every section. What lends continuity to the text is Balaustion, narrator and main character, spectator and performer: with her performative speech-acts, it is she who directs the succession of diegesis and mimesis. Finally, the poem has also a metapoetic function, that consists in the glorification of the extraordinary power of poetry.

description: Deep brain stimulation (DBS) is a neurological intervention to treat neurological diseases such as Parkinson’s disease. The postoperative position determination of the electrode is critical to determine if the surgery was successful. This study aimed to develop a human head phantom by using additive manufacturing (AM). With these phantom new findings in postoperative position determination on computed tomography images can be gained. Necessary to that end, the head phantom should be as anatomically correct as possible. Furthermore, the brain and the bones should be represented with realistic CT values on computed tomography (CT) images. The first measurements showed that the CT values of the 3D printed skull correspond to the CT values of the human skull and the CT values of the phantom’s brain are equivalent to values slightly above these of the human brain.

description: In the effort of a surgeon to overcome in the best possible way a difficult surgical event such as the removal of tumors from liver, it is required the use of all possible imaging-diagnostic tools to familiarize the doctor with the current patient’s situation. Even though tomography images are implying the 3D geometry of the human body they are not providing in a manageable way specific 3D model structures of separate organs. The present work concerns the use of 3D modeling techniques to produce 3D physical model of both liver and its internal geometry (vessels, tumor) using a 3D printer.

description: We investigate dilaton-gravity models whose solutions contain a large portion of the static patch of dS$_2$. The thermodynamic properties of these theories are considered both in the presence of a finite Dirichlet wall, as well as for asymptotically near-AdS$_2$ boundaries. We show that under certain circumstances such geometries, including those endowed with an asymptotically near-AdS$_2$ boundary, can be locally and even globally thermodynamically stable within particular temperature regimes. First order phase transitions reminiscent of the Hawking-Page transition are discussed. For judiciously chosen models, the near-AdS$_2$ boundary can be viewed as a completion of the stretched cosmological dS$_2$ horizon. We speculate on candidate microphysical models.

description: Searches for dark matter decaying into photons constrain its lifetime to be many orders of magnitude larger than the age of the Universe. A corollary statement is that the abundance of any particle that can decay into photons over cosmological timescales is constrained to be much smaller than the cold dark-matter density. We show that an $\textit{irreducible}$ freeze-in contribution to the relic density of axions is in violation of that statement in a large portion of the parameter space. This allows us to set stringent constraints on axions in the mass range $100\rm \;eV - 100\; MeV$. At $10\rm \; keV$ our constraint on a photophilic axion is $g_{aγγ} \lesssim 8.1 \times 10^{-14}~{\rm GeV}^{-1}$, almost three orders of magnitude stronger than the bounds established using horizontal branch stars; at $100~{\rm keV}$ our constraint on a photophobic axion coupled to electrons is $g_{aee} \lesssim 8.0 \times 10^{-15}$, almost four orders of magnitude stronger than present results. Although we focus on axions, our argument is more general and can be extended to, for instance, sterile neutrinos.

Exact Solution for Statics and Dynamics of Maximal Entropy Random Walk on Cayley Trees

description: We provide analytical solutions for two types of random walk: generic random walk (GRW) and maximal entropy random walk (MERW) on a Cayley tree with arbitrary branching number, root degree, and number of generations. For MERW, we obtain the stationary state given by the squared elements of the eigenvector associated with the largest eigenvalue $λ_0$ of the adjacency matrix. We discuss the dynamics, depending on the second largest eigenvalue $λ_1$, of the probability distribution approaching to the stationary state. We find different scaling of the relaxation time with the system size, which is generically shorter for MERW than for GRW. We also signal that depending on the initial conditions there are relaxations associated with lower eigenvalues which are induced by symmetries of the tree. In general, we find that there are three regimes of a tree structure resulting in different statics and dynamics of MERW; these correspond to strongly, critically, and weakly branched roots.

description: We unveil a topological phase of interacting fermions on a two-leg ladder of unequal parity orbitals, derived from the experimentally realized double-well lattices by dimension reduction. $Z_2$ topological invariant originates simply from the staggered phases of $sp$-orbital quantum tunneling, requiring none of the previously known mechanisms such as spin-orbit coupling or artificial gauge field. Another unique feature is that upon crossing over to two dimensions with coupled ladders, the edge modes from each ladder form a parity-protected flat band at zero energy, opening the route to strongly correlated states controlled by interactions. Experimental signatures are found in density correlations and phase transitions to trivial band and Mott insulators.

description: The aim of this study is to analyze the stability of Alfven Eigenmodes (AE) in the China Fusion Engineering Test Reactor (CFETR) plasma for steady state operations. The analysis is done using the gyro-fluid code FAR3d including the effect of the acoustic modes, EP Finite Larmor radius damping effects and multiple energetic particle populations. Two high poloidal beta scenarios are studied with respect to the location of the internal transport barrier (ITB) at r/a = 0.45 (case A) and r/a = 0.6 (case B). Both operation scenarios show a narrow TAE gap between the inner-middle plasma region and a wide EAE gap all along the plasma radius. The AE stability of CFETR plasmas improves if the ITB is located inwards, case A, showing AEs with lower growth rates with respect to the case B. The AEs growth rate is smaller in the case A because the modes are located in the inner-middle plasma region where the stabilizing effect of the magnetic shear is stronger with respect to the case B. Multiple EP populations effects (NBI driven EP + alpha articles) are negligible for the case A, although the simulations for the case B show a stabilizing effect of the NBI EP on the n=1 BAE caused by alpha particles during the thermalization process. If the FLR damping effects are included in the simulations, the growth rate of the EAE/NAE decreases up to 70 %, particularly for n > 3 toroidal families. Low n AEs (n<6) show the largest growth rates. On the other hand, high $n$ modes (n=6 to 15) are triggered in the frequency range of the NAE, strongly damped by the FLR effects.

description: Spina Bifida is a congenital defect that exposes the spinal cord to fluids in the womb. Severe cases of Spina Bifida can result in partial or complete paralysis, inability to walk, and/or bladder and bowel dysfunction. Surgeons perform in utero Spina Bifida repair to prevent the progressive damage to the exposed neural tissue before birth. As in utero Spina Bifida repair becomes the standard of care, pediatric neurosurgeons are exploring novel diagnostic and planning tools, like 3D segmentation and 3D printing, to prepare for the procedure and educate expecting parents.

Unidirectional segregation of Bright-Bright soliton through a $\mathcal{PT}$-symmetric potential

description: We study the dynamics of two-component vector solitons, namely, bright-bright (BB) solitons interacting with parity-time-($\mathcal{PT}$) symmetric potentials. We employ direct numerical simulations to demonstrate the unidirectional segregation of the BB soliton. Using a modified perturbed dynamical variational Lagrangian approximation, we develop an analytical model to verify the results obtained from the numerical calculations. Simplified variational equations of motion suggest that the splitting of BB solitons can be explained by considering the effective force between the two components.
