description: We present the theory of a pair of atoms in a one-dimensional optical lattice interacting via a narrow Feshbach resonance. Using a two-channel description of the resonance, we derive analytic results for the scattering states inside the continuum band and the discrete bound states outside the band. We identify a Fano resonance profile, and the survival probability of a molecule when swept through the Bloch band of scattering states by varying an applied magnetic field. We discuss how these results may be used to investigate the importance of the structured nature of the continuum in experiments.

description: We consider the dynamics of the open string tachyon condensation in a framework of the cubic fermionic String Field Theory including a non-minimal coupling with closed string massless modes, the graviton and the dilaton. Coupling of the open string tachyon and the dilaton is motivated by the open String Field Theory in a linear dilaton background and the flat space-time. We note that the dilaton gravity provides several restrictions on the tachyon condensation and show explicitly that the influence of the dilaton on the tachyon condensation is essential and provides a significant effect: oscillations of the Hubble parameter and the state parameter become of a cosmological scale. We give an estimation for the period of these oscillations (0.1-1) Gyr and note a good agreement of this period with the observed oscillations with a period (0.15-0.65) Gyr in a distribution of quasar spectra.

description: We demonstrate that the interaction between excitons and a sea of incoherent electrons does not preclude excitons dressing by light. We investigate the role of exciton-electron scattering in the light dressing by measuring the dynamical absorption spectrum of a modulation-doped CdTe quantum well, which shows a clear evidence for significant electron scattering of the excitonic states. We show the occurrence of dressed and correlated excitons by detecting quantum coherent interferences through excitonic Autler-Townes doublet and ac Stark splitting, which evolves to Mollow triplet with gain. We also evidence the partial inhibition of the electron-exciton scattering by exciton-light coupling.
Effect of radiation on transport in graphene

description: We study transport properties of graphene-based p-n junctions irradiated by an electromagnetic field (EF). The resonant interaction of propagating quasiparticles with an external monochromatic radiation opens dynamical gaps in their spectrum, resulting in a strong modification of current-voltage characteristics of the junctions. The values of the gaps are proportional to the amplitude of EF. We find that the transmission of the quasiparticles in the junctions is determined by the tunneling through the gaps, and can be fully suppressed when applying a sufficiently large radiation power. However, EF can not only suppress the current but also generate it. We demonstrate that if the height of the potential barrier exceeds a half of the photon energy, the directed current (photocurrent) flows through the junction without any dc bias voltage applied. Such a photocurrent arises as a result of inelastic quasiparticle tunneling assisted by one- or two-photon absorption. We calculate current-voltage characteristics of diverse graphene based junctions and estimate their parameters necessary for the experimental observation of the photocurrent and transmission suppression.

description: We congratulate Lee, Nadler and Wasserman (henceforth LNW) on a very interesting paper on new methodology and supporting theory [arXiv:0707.0481]. Treelets seem to tackle two important problems of modern data analysis at once. For datasets with many variables, treelets give powerful predictions even if variables are highly correlated and redundant. Maybe more importantly, interpretation of the results is intuitive. Useful insights about relevant groups of variables can be gained. Our comments and questions include: (i) Could the success of treelets be replicated by a combination of hierarchical clustering and PCA? (ii) When choosing a suitable basis, treelets seem to be largely an unsupervised method. Could the results be even more interpretable and powerful if treelets would take into account some supervised response variable? (iii) Interpretability of the result hinges on the sparsity of the final basis. Do we expect that the selected groups of variables will always be sufficiently small to be amenable for interpretation?

Probing the Solar Meridional Circulation using Fourier Legendre Decomposition

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We apply the helioseismic methodology of Legendre Function Decomposition to 88 months of Dopplergrams obtained by the Helioseismic and Magnetic Imager (HMI) as the basis of inferring the depth variation of the mean meridional flow, as averaged between 20 and 60 degrees latitude and in time, in both the northern and southern hemispheres. We develop and apply control procedures designed to assess and remove center-to-limb artifacts, using measurements obtained by performing the analysis with respect to artificial poles at the east and west limbs. Forward modeling is carried out, using sensitivity functions proportional to the mode kinetic energy density, to evaluate the consistency of the corrected frequency shifts with models of the depth variation of the meridional circulation in the top half of the convection zone. The results, taken at face value, imply substantial differences between the meridional circulation in the northern and southern hemisphere. The inferred presence of a return (equator-ward propagating) flow at a depth of approximately 40 Mm below the photosphere in the northern hemisphere is surprising and appears to be inconsistent with many other helioseismic analyses. This discrepancy may be the result of an inadequacy of our methodology to remove systematic errors in HMI data. Our results appear to be at least qualitative similar to those by Gizon et al. (2020) which point to an anomaly in HMI data that is not present in MDI or GONG data.

description: Nuclear rings are sites of intense star formation at the centers of barred galaxies. To understand what determines the structure and star formation rate (SFR; $\dot{M}_{\rm SF}$) of nuclear rings, we run semi-global, hydrodynamic simulations of nuclear rings subject to constant mass inflow rates $\dot{M}_{\rm in}$. We adopt the TIGRESS framework of Kim \& Ostriker to handle radiative heating and cooling, star formation, and related supernova (SN) feedback. We find that the SN feedback is never strong enough to destroy the ring or quench star formation everywhere in the ring. Under the constant $\dot{M}_{\rm in}$, the ring star formation is very steady and persistent, with the SFR exhibiting only mild temporal fluctuations. The ring SFR is tightly correlated with the inflow rate as $\dot{M}_{\rm SF}\approx 0.8\dot{M}_{\rm in}$, for a range of $\dot{M}_{\rm in}=0.125-8\,M_\odot\,{\rm yr}^{-1}$. Within the ring, vertical dynamical equilibrium is maintained, with the midplane pressure (powered by SN feedback) balancing the weight of the overlying gas. The SFR surface density is correlated nearly linearly with the midplane pressure, as predicted by the pressure-regulated, feedback-modulated star formation theory. Based on our results, we argue that the ring SFR is causally controlled by $\dot{M}_\text{in}$, while the ring gas mass adapts to the SFR to maintain the vertical dynamical equilibrium under the gravitational field arising from both gas and stars.

description: Adler and van Moerbeke \cite{AVM} described a reduction of 2D-Toda hierarchy called Toeplitz lattice. This hierarchy turns out to be equivalent to the one originally described by Ablowitz and Ladik \cite{AL} using semidiscrete zero-curvature equations. In this paper we obtain the original semidiscrete zero-curvature equations starting directly from the Toeplitz lattice and we generalize these computations to the matrix case. This generalization lead us to the semidiscrete zero-curvature equations for the non-abelian (or multicomponent) version of Ablowitz-Ladik equations \cite{GI}. In this way we extend the link between biorthogonal polynomials on the unit circle and Ablowitz-Ladik hierarchy to the matrix case.

The previously reported Ih symmetric structure is not an energy minimum in the potential energy surface and exhibits a spontaneous symmetry breaking to yield a puckered cage with a rare Th symmetry. The HOMO-LUMO gap is twice as large as the reported value and amounts to 1.94 eV at B3LYP/6-31G(d) level. The valence orbital structure of boron buckyball is identical to the one in the carbon analogue.

Dialoguing through ‘deficiting’? Transforming science communication in radiological protection research

description: European nuclear policy and research programs increasingly emphasize the importance of initiating dialogue with citizens and ‘public participation’ in nuclear research and development (R&D). In this presentation, I consider how these formally-sanctioned appeals to participatory science communication are received and enacted in nuclear R&D spaces. Based on my interdisciplinary work as a social scientist in radiological protection, I illustrate how colleagues (nuclear scientists, engineers, safety personnel) increasingly show awareness of the challenges of publicly communicating science, while continuing to view the public as ignorant of science and in need of science education. Whereas this deficit view has been widely criticized by social scientists studying the public communication of science, I argue that it can facilitate the ‘opening up’ of R&D processes to wider publics and considerations when it is clearly differentiated from contending science communication models and practices. Social scientists can help to make differentiation of this kind instructive and potentially transformative for all stakeholders, not by insisting on symmetrical, two-way dialogue between them but by urging them to articulate and refine their views in confrontation with competing problem definitions, stakes, and evidence.

description: We suggest to combine the Anthropic Principle with Many-Worlds Interpretation of Quantum Theory. Realizing the multiplicity of worlds it provides an opportunity of explanation of some important events which are assumed to be extremely improbable. The Mesoscopic Anthropic Principle suggested here is aimed to explain appearance of such events which are necessary for emergence of Life and Mind. It is complementary to Cosmological Anthropic Principle explaining the fine tuning of fundamental constants. We briefly discuss various possible applications of Mesoscopic Anthropic Principle including the Solar Eclipses and assembling of complex molecules. Besides, we address the problem of Time's Arrow in the framework of Many-World Interpretation. We suggest the recipe for disentangling of quantities defined by fundamental physical laws and by an anthropic selection.

description: We present a study of the relationship between the deficiency of neutral hydrogen and the local three-dimensional number density of spiral galaxies in the Arecibo catalog of global HI measurements (Springob et al. 2005). We find that the dependence on density of the HI content is weak at low densities, but increases sharply at high densities where interactions between galaxies and the intra-cluster medium become important. This behavior is reminiscent of the morphology-density relation (Dressler 1980) in that the effect manifests itself only at cluster-type densities, and indeed when we plot both the HI deficiency-density and morphology-density relations, we see that the densities at which they "turn up" are similar. This suggests that the physical mechanisms responsible for the increase in early types in clusters are also responsible for the decrease in HI content.

description: Constitutive functions that govern macroscale capillary pressure and relative permeability are central in constraining both storage efficiency and sealing properties of CO$_2$ storage systems. Constitutive functions for porous systems are in part determined by wettability, which is a pore-scale phenomenon that influences macroscale displacement. While wettability of saline aquifers and caprocks are assumed to remain water-wet when CO$_2$ is injected, there is recent evidence of contact angle change due to long-term CO$_2$ exposure. Weakening of capillary forces alters the saturation functions dynamically over time. Recently, new dynamic models were developed for saturation functions that capture the impact of wettability alteration (WA) due to long-term CO$_2$ exposure. In this paper, these functions are implemented into a two-phase two-component simulator to study long-term WA dynamics for field-scale CO$_2$ storage. We simulate WA effects on horizontal migration patterns under injection and buoyancy-driven migration in the caprock. We characterize the behavior of each scenario for different flow regimes. Our results show the impact on storage efficiency can be described by the capillary number, while vertical leakage can be scaled by caprock sealing parameters. Scaling models for CO$_2$ migration into the caprock show that long-term WA poses little risk to CO$_2$ containment over relevant timescales.

description: We demonstrate a graphene-MoS2 architecture integrating multiple field-effect transistors and we independently probe and correlate the conducting properties of van der Waals coupled graphene-MoS2 contacts with the ones of the MoS2 channels. Devices are fabricated starting from high-quality single-crystal monolayers grown by chemical vapor deposition and characterized by scanning Raman and photoluminescence spectroscopies. Transconductance curves of MoS2 are compared with the current-voltage characteristics of graphene contact stripes, revealing a significant suppression of transport on the n-side of the transconductance curve. Based on ab-initio modeling, the effect is understood in terms of trapping by sulfur vacancies, which counter-intuitively depends on the field-effect, even though the graphene contact layer is positioned between the backgate and the MoS2 channel.

description: Boom cranes are among the most common material handling systems due to their simple design. Some boom cranes also have an auxiliary jib connected to the boom with a flexible joint to enhance the maneuverability and increase the workspace of the crane. Such boom cranes are commonly called knuckle boom cranes. Due to their underactuated properties, it is fairly challenging to control knuckle boom cranes. To the best of our knowledge, only a few techniques are present in the literature to control this type of cranes using approximate models of the crane. In this paper we present for the first time a complete mathematical model for this crane where it is possible to control the three rotations of the crane (known as luff, slew, and jib movement), and the cable length. One of the main challenges to control this system is how to reduce the oscillations in an effective way. In this paper we propose a nonlinear control based on energy considerations capable of guiding the crane to desired sets points while effectively reducing load oscillations. The corresponding stability and convergence analysis is proved using the LaSalle's invariance principle. Simulation results are provided to demonstrate the effectiveness and feasibility of the proposed method.

(This is analogous to the stability theorem of Kahler manifolds by Kodaira-Spencer.) We apply the stability theorem to a class of compact Kahler manifolds which admits deformations to generalized complex manifolds and obtain non-trivial generalized Kahler structures on Fano surfaces and toric Kahler manifolds. In particular, we show that holomorphic Poisson structures on a Kahler manifold induce deformations of generalized Kahler structures.

description: We report on the optical identification of the companion to the eclipsing millisecond pulsar PSR J1701$-$3006B in the globular cluster NGC 6266. A relatively bright star with an anomalous red colour and an optical variability ($\sim$ 0.2 mag) that nicely correlates with the orbital period of the pulsar ($\sim$ 0.144 days) has been found nearly coincident with the pulsar nominal position. This star is also found to lie within the error box position of an X-ray source detected by Chandra observations, thus supporting the hypothesis that some interaction is occurring between the pulsar wind and the gas streaming off the companion. Although the shape of the optical light curve is suggestive of a tidally deformed star which has nearly completely filled its Roche lobe, the luminosity ($\sim 1.9 L_\odot$) and the surface temperature ($\sim 6000$ K) of the star, deduced from the observed magnitude and colours, would imply a stellar radius significantly larger than the Roche lobe radius. Possible explanations for this apparent inconsistency are discussed.

description: The hallmark property of two-dimensional topological materials is the incredible robustness of the quantized Hall conductivity to disorder. That robustness arises from the fact that in the topological band gap, transport can occur only along the edges modes, which are immune to scattering. However, for sufficiently strong disorder, the band gap closes and the system becomes topologically trivial as all states become localized, such that all transport vanishes -- in accordance with Anderson localization. It therefore came as a surprise when it was suggested that, for a two-dimensional quantum spin-Hall topological system, the opposite could occur. In so-called topological Anderson insulators, the emergence of protected edge states and quantized transport is caused by the introduction of disorder. However, to date, the observation of the topological Anderson insulator phase has been elusive. In this article, we report the first experimental demonstration of a topological Anderson insulator. We do that in a photonic implementation: an array of helical, evanescently-coupled waveguides in a detuned honeycomb geometry. Under proper conditions, adding on-site disorder, in the form of random variations in the refractive index contrast defining the waveguides, drives the system from a trivial phase into a topological state.

description: We present angle-resolved photoemission spectroscopy (ARPES) data on moderately underdoped La$_{1.855}$Sr$_{0.145}$CuO$_4$ at temperatures below and above the superconducting transition temperature. Unlike previous studies of this material, we observe sharp spectral peaks along the entire underlying Fermi surface in the superconducting state. These peaks trace out an energy gap that follows a simple {\it d}-wave form, with a maximum superconducting gap of 14 meV. Our results are consistent with a single gap picture for the cuprates. Furthermore our data on the even more underdoped sample La$_{1.895}$Sr$_{0.105}$CuO$_4$ also show sharp spectral peaks, even at the antinode, with a maximum superconducting gap of 26 meV.

description: The determination of absolute and relative distances of molecular clouds along the line-of-sight towards the central molecular zone (CMZ) is crucial to infer its orbital structure, dynamics, and to understand star formation in the clouds. Recent results by Zoccali et al. 2021 suggest that the G0.253 + 0.016 cloud (the Brick) does not belong to the CMZ. This motivated us to cross check their results computing the absolute and relative distance to the Brick and also to other two molecular clouds (the 50 km/s, and the 20 km/s clouds), and discuss their CMZ membership. We used the colour magnitude diagrams $K_s$ vs. $H-K_s$ to compare stars detected towards the target clouds with stars detected towards three reference regions in the nuclear stellar disc (NSD) and the Galactic bulge. We used red clump (RC) stars to estimate the distance to each region. We obtained that all the clouds present a double RC feature. Such a double RC has been reported in previous work for the NSD, but not for the bulge adjacent to it. We exclude the possibility that the different RC features are located at significantly different distances. The obtained absolute and relative distances are compatible with the Galactic centre distance ($\sim8$ kpc).

description: The J-PARC muon $g - 2$/EDM experiment aims to measure the muon magnetic moment anomaly $a_μ = (g -2) / 2 ~ $ and the muon electric dipole moment (EDM) $d_μ$. The target sensitivity for $a_μ$ is a statistical uncertainty of $450 \times 10^{-9}$, and for $d_μ$ it is $1.5 \times 10^{-21}$ $e \cdot \rm{cm}$. The readout electronics require a DC to DC converter to provide 1.5 V and 3.3 V electric voltage within a specific environment. To capture the positron decay from the muon, the detector components are placed in the muon storage area where a 3 T magnetic field is applied in a vacuum. The extra magnetic field from the converter should be less than 30 $μ$T to reach the aforementioned sensitivity on $a_μ$. In addition, the electric field produced by the converter has to be as small as 1 V/m to also reach the target sensitivity on $d_μ$. For this purpose, we develop a step-down converter. We discuss the development process and the performance of our DC to DC converter for the J-PARC muon $g - 2$/EDM experiment.

description: Keeping track of scientific challenges, advances and emerging directions is a fundamental part of research. However, researchers face a flood of papers that hinders discovery of important knowledge. In biomedicine, this directly impacts human lives. To address this problem, we present a novel task of extraction and search of scientific challenges and directions, to facilitate rapid knowledge discovery. We construct and release an expert-annotated corpus of texts sampled from full-length papers, labeled with novel semantic categories that generalize across many types of challenges and directions. We focus on a large corpus of interdisciplinary work relating to the COVID-19 pandemic, ranging from biomedicine to areas such as AI and economics. We apply a model trained on our data to identify challenges and directions across the corpus and build a dedicated search engine. In experiments with 19 researchers and clinicians using our system, we outperform a popular scientific search engine in assisting knowledge discovery. Finally, we show that models trained on our resource generalize to the wider biomedical domain and to AI papers, highlighting its broad utility. We make our data, model and search engine publicly available. https://challenges.apps.allenai.org/

description: We studied experimentally the effect of grain size and maximum load on the compaction and subsequent relaxation of a granular column when it is subjected to vertical uniaxial compression. The experiments were performed using two different types of grains: 1) solid glass beads, and 2) porous beads that consist of agglomerates of glass powder. We found that the compression force increases non-linearly with time, with sudden drops for the case of glass beads and periodic undulations for dust particles. Whereas the grain size effect is small in the average force load, the fluctuations become larger as the grain size increases. On the other hand, the relaxation process is well described by the Maxwell model with three different relaxation time scales.

Abstract:

"A prototype stand-off scanning laser-induced breakdown spectroscopy(LIBS) device for mine wall imaging is designed, built and tested in practice. The hardware and software design of the prototype device and a brief analysis of first experimental results are presented. Introduction part reviews the theory and current applications of LIBS. The design choices are laid out in detail and evaluated in their advantages in disadvantages. The end result is a highly automated scanning measurement device, which is also tested in practical tests. The primary experimental results demonstrate the feasibility of a standoff scanning LIBS device in harsh mine conditions and great potential value in the elemental heatmaps acquired with the device."

title: CRISPR/Cas9-mediated genome engineering of the SMARCB1 gene locus
Creators: name: Lechler, Marion Brigitte
Publisher: name: UNSPECIFIED
Year: 2021

description: Truncating or nonsense mutations in the ubiquitously expressed tumour suppressor gene and BAF chromatin remodelling complex core subunit SMARCB1 cause malignant rhabdoid tumours (MRTs) of the brain, kidney, and the soft tissues. MRTs show a high clinical variance despite a simple cancer genome with SMARCB1 being the only gene recurrently mutated in these malignancies. MRTs of the brain are called atypical teratoid/rhabdoid tumours (AT/RT) and present a rare, but highly aggressive brain tumour entity with poor prognosis that predominantly occur in very young children. In this thesis, diverse constructs for the generation of three-colour-reporter cell lines with SMARCB1 mutations found in AT/RTs were established and methods required for the CRISPR/Cas9-mediated genome engineering using these constructs were optimised. Heterozygous missense mutations or small in-frame deletions clustering in the last two exons of the SMARCB1 gene are frequently observed in another disease entity, Coffin Siris-syndrome (CSS). CSS is a congenital neurodevelopmental disorder characterised by cognitive impairment, microcephaly, coarse facial features, and hypoplasia of the fifth finger- and/or toenail as well of the distal phalanx of the fifth finger and/or toe. CRISPR/Cas9 constructs for the generation of hiPSC and MCF10A cell lines with heterozygous c.1091_1093del AGA SMARCB1 mutation were generated to investigate the cellular consequences of this mutation. Comparison of cellular AT/RT and CSS models would contribute to a better understanding of how different types of SMARCB1 mutations can lead to two very different diseases and how particular mutations affect the gene expression of SMARCB1 itself. The recently published mouse model recapitulating SMARCB1-associated features of CSS, which is based on a partial loss-of-function of Smarcb1, revealed a diminished pool of neural progenitor cells (NPC) in the developing brain of these mice. To test the hypothesis if overexpression of Hes5 can rescue the impairment in mouse neural stem cells (NSC) maintenance, a lentiviral system for the overexpression of Cre recombinase and of Hes5 in Smarcb1(+/flox) NSCs and NPCs was optimised.
Ascoltare (e far ascoltare) il melodramma: qualche istruzione per l’uso

description: In the present cultural situation it’s hard for students approaching to the world of lyric opera (on the contrary, modern technological opportunities might make it very easy).
First of all, it is important remembering them that opera is about theatre, a dramatic performance that employs music as its main way of communication: that’s why the librettos have to be considered very seriously. One must explain carefully the stories they tell, trying to fill the linguistic and cultural gaps not easily understandable today.
A way of smoothing the approach could be introducing previously those types of opera that mix spoken and sung performance: musical, opéra-comique, Singspiel, melodrama.
Very important results weaving the cultural and historical fabric of the times when an opera is born, and the sources of its libretto (dramas, novels, historiography): furthermore, stressing spots and links with contemporary external data.
However, it is not less important stressing the opposite direction: that means, how much literature, arts and ultimately movies owe to opera.
Finally, during an opera different chronological times are represented, expressed by different techniques and fixed in different musical structures. They all contribute to assemble the complex general architecture an opera consists of: analyzing and dissecting that machine is surely a good exercise for young students (even for more aged people).

description: Microbial pathogens cause millions of cases of foodborne disease all over the world and result in many hospitalizations and deaths. For this reason an effective consumer education programs to promote safer food handling practices and other averting behaviors can increase the consumer awareness of microbial pathogens. In this paper the awareness of consumers of food poisoning and its clinical signs, risky foods, practice and proper selection of ready food and major microbial pathogens as food safety problems in Taif region is tested, a pretested self-administered questionnaire was used anonymously among representative samples in Taif city in different points of the city. 71% of the samples tested think they have been affected by food poisoning, 49% of the samples have information about salmonella as a foodborne pathogen while 16% only have mentioned Campylobacter as a foodborne pathogen. The awareness varies among pathogens and the variations appear to be related to differences in the number and severity of illnesses associated with these pathogens. The present investigations revealed that awareness of microbial pathogens was associated with food safety Perceptions, awareness of potentially risky foods and substances associated with potential food safety hazards, food safety related behaviors, and demographics. There are different effects of variables on awareness of the tested pathogens.
