Effect of estrogen suppression on lung function in pulmonary Lymphangioleiomyomatosis
Creators: name: Contini, Paola <1975>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2012
Subjects: MED/10 Malattie dell'apparato respiratorio

description: Background: Lymphangioleiomyomatosis (LAM), a rare progressive disease, is characterized by the proliferation of abnormal smooth muscle cells (LAM cells) in the lung, which leads to cystic parenchymal destruction and progressive respiratory failure. Estrogen receptors are present in LAM cells. LAM affects almost exclusively women of childbearing age. These findings, along with reports of disease progression during pregnancy or treatment with exogenous estrogens, have led to the assumption that hormonal factors play an important role in the pathogenesis of LAM. So, various therapies aim at preventing estrogen receptors (ER) by lowering circulating estrogen levels, by trying to block ER activity, or by attempting to lower ER expression in LAM. Prior experience have yielded conflicting results. 
Objective: The goal of this study was to evaluate, retrospectively, the effect of estrogen suppression in 21 patients with LAM.
Design: We evaluated hormonal assays, pulmonary function tests and gas-exchange at baseline and after 12, 24 and 36 months after initiating hormonal manipulation.
Results: The mean yearly rates of decline in FEV1 and DLCO are lower than those observed in prior studies and just DLCO decline was statistically significant. We also found an improvement of mean value of FVC and PaO2.
Conclusions: Estrogen suppression appears to prevent decline in lung function in LAM.

description: Sea-level variability is characterized by multiple interacting factors described in the Fourth Assessment Report (Bindoff et al., 2007) of the Intergovernmental  Panel on Climate Change (IPCC) that act over wide spectra of temporal and spatial scales.  In Church et al. (2010) sea-level variability and changes are defined as manifestations of climate variability and change. The European Environmental Agency (EEA) defines sea level as one of most important indicators for monitoring climate change, as it integrates the response of different components of the Earths system and is also affected by anthropogenic contributions (EEA, 2011).
 
The balance between the different sea-level contributions represents an important source of uncertainty, involving stochastic processes that are very difficult to describe and understand in detail, to the point that they are defined as an enigma in Munk (2002). Sea-level rate estimates are affected by all these uncertainties, in particular if we look at possible responses to sea-level contributions to future climate.
At the regional scale, lateral fluxes also contribute to sea-level variability, adding complexity to sea-level dynamics. 
The research strategy adopted in this work to approach such an interesting
and challenging topic has been to develop an objective methodology to study sea-level variability at different temporal and spatial scales, applicable in each part of  the Mediterranean basin in particular, and in the global ocean in general, using all the best calibrated sources of data (for the Mediterranean): in-situ, remote-sensig and numerical models data. The global objective of this work was to achieve a deep understanding of all of the components of the sea-level signal contributing to sea-level variability,
tendency and trend and to quantify them.

description: Terahertz (THz) time-domain emission spectroscopy was performed on layered 2H-MoSe2 and 2H-WSe2. The THz emission shows an initial cycle attributed to surge currents and is followed by oscillations attributed to coherent interlayer phonon modes. To obtain the frequencies of the interlayer vibrations, analysis of the THz emission waveforms were performed, separating the two contributions to the total waveform. Results of the fitting show several vibrational modes in the range of 5.87 to 32.75 cm-1 for the samples, attributed to infrared-active interlayer shear and breathing modes. This study demonstrates that THz emission spectroscopy provides a means of observing these low frequency vibrational modes in layered materials.

description: The abrupt outbreak of the COVID-19 pandemic was the most significant event in 2020, which had profound and lasting impacts across the world. Studies on energy markets observed a decline in energy demand and changes in energy consumption behaviors during COVID-19. However, as an essential part of system operation, how the load forecasting performs amid COVID-19 is not well understood. This paper aims to bridge the research gap by systematically evaluating models and features that can be used to improve the load forecasting performance amid COVID-19. Using real-world data from the New York Independent System Operator, our analysis employs three deep learning models and adopts both novel COVID-related features as well as classical weather-related features. We also propose simulating the stay-at-home situation with pre-stay-at-home weekend data and demonstrate its effectiveness in improving load forecasting accuracy during COVID-19.

description: Generalized virial theorem for quantum mechanical nonrelativistic and relativistic systems with translational and rotational symmetry is derived in the form of the commutator between the generator of dilations G and the Hamiltonian H. If the conditions of translational and rotational symmetry together with the additional conditions of the theorem are satisfied, the matrix elements of the commutator [G, H] are equal to zero on the subspace of the Hilbert space. Normalized simultaneous eigenvectors of the particular set of commuting operators which contains H, J^{2}, J_{z} and additional operators form an orthonormal basis in this subspace. It is expected that the theorem is relevant for a large number of quantum mechanical N-particle systems with translational and rotational symmetry.

description: The detection of rotational transitions of the AlO radical at millimeter wavelengths from an astronomical source has recently been reported. In view of this, rotational transitions in the ground X^2 Sigma^+ state of AlO have been reinvestigated. Comparisons between Fourier transform and microwave data indicate a discrepancy regarding the derived value of gamma_D in the v = 0 level of the ground state. This discrepancy is discussed in the light of comparisons between experimental data and synthesized rotational spectra in the v = 0, 1 and 2 levels of X^2 Sigma^+. A list of calculated rotational lines in v = 0, 1 and 2 of the ground state up to N' = 11 is presented which should aid astronomers in analysis and interpretation of observed AlO data and also facilitate future searches for this radical.

description: The specific heat of high-purity $\rm Ba_{0.68}K_{0.32}Fe_2As_2$ single crystals with the highest reported superconducting $T_c$ = 38.5 K was studied. The electronic specific heat, $C_p$, below $T_c$ shows two gap features, with $Δ_1 \approx 11$ meV and $Δ_2 \approx 3.5$ meV obtained from an $α$-model analysis. The reduced gap value, $2Δ^{\rm max} / k_B T_c \approx 6.6$, the magnitude of the specific heat jump, $ΔC_p(T_c)/T_c$, and its slope below $T_c$ exhibit strong-coupling character. We also show that an Eliashberg model with two hole and two electron bands gives the correct values of $T_c$, the superconducting gaps, and the temperature dependence of the free-energy difference.

Subjects: CHIM/03 Chimica generale e inorganica

description: This work of thesis involves various aspects of crystal engineering. Chapter 1 focuses on crystals containing crown ether complexes. Aspects such as the possibility of preparing these materials by non-solution methods, i.e. by direct reaction of the solid components, thermal behavior and also isomorphism and interconversion between hydrates are taken into account. 
In chapter 2 a study is presented aimed to understanding the relationship between hydrogen bonding capability and shape of the building blocks chosen to construct crystals. The focus is on the control exerted by shape on the organization of sandwich cations such as cobalticinium, decamethylcobalticinium and bisbenzenchromium(I) and on the aggregation of monoanions all containing carboxylic and carboxylate groups, into 0-D, 1-D, 2-D and 3-D networks.
Reactions conducted in multi-component molecular assemblies or co-crystals have been recognized as a way to control reactivity in the solid state. The [2+2] photodimerization of olefins is a successful demonstration of how templated solid state synthesis can efficiently synthesize unique materials with remarkable stereoselectivity and under environment-friendly conditions. A  demonstration of this synthetic strategy is given in chapter 3. 
The combination of various types of intermolecular linkages, leading to formation of high order aggregation and crystalline materials or to a random aggregation resulting in an amorphous precipitate, may not go to completeness. In such rare cases an aggregation process intermediate between crystalline and amorphous materials is observed, resulting in the formation of a gel, i.e. a viscoelastic solid-like or liquid-like material.
In chapter 4 design of new Low Molecular Weight Gelators is presented. Aspects such as the relationships between molecular structure, crystal packing and gelation properties and the application of this kind of gels as a medium for crystal growth of organic molecules, such as APIs, are also discussed.

We characterize commutative (A-)loops with middle nucleus of index 2 and solve the isomorphism problem. Using this characterization and certain central extensions based on trilinear forms, we construct several classes of commutative A-loops of order a power of 2. We initiate the classification of commutative A-loops of small orders and also of order $p^3$, where $p$ is a prime.

description: Obiettivo: studio longitudinale di una coorte di gravidanze gemellari e valutazione di eventuali correlazioni tra specifici parametri cardiaci materni ed esito sfavorevole della gravidanza.
Metodi: Sono state arruolate in modo prospettico donne con gravidanze gemellari, sottoposte a controlli seriati della funzione  cardiaca  materna ( 20-23 settimane; 26-29 settimane e 30-33 settimane). Le pazienti in cui il parto si è verificato prima della 34°settimana compiuta di gestazione sono state escluse a priori dallo studio.
Specifici parametri cardiaci campionati sono stati confrontati tra il gruppo di gravidanze con esito positivo ed il gruppo di pazienti che hanno sviluppato complicanze nel corso della gravidanza quali: preeclampsia o ipertensione gestazionale, basso peso alla nascita  ( SGA:  peso neonatale di uno o entrambi i feti < 5° centile per l’epoca di gestazione).
Risultati: sono state incluse nello studio 28 gravidanze gemellari,di cui 8 complicate. Durante ogni visita abbiamo osservato un aumento significativo della gittata cardiaca ( CO ) e sistolica ( SV ) ed una caduta delle resistenze vascolari totali ( TVR ) nelle gravidanze gemellari normali vs complicate. Inoltre, CO, pressione arteriosa (BP), frequenza cardiaca ( HR ) e TVR son rimaste invariate nel corso dei controlli ambulatoriali per le gravidanze con esiti sfavorevole, mentre mostravano modificazioni significative ( CO, HR e BDP in aumento; TVR in diminuzione ) nel gruppo di pazienti con esito favorevole della gravidanza.
Conclusioni: La valutazione longitudinale della funzione cardiaca materna sembra dimostrare una significativa differenza tra i valori dei parametri cardiaci materni delle gravidanze multiple non complicate, rispetto a quelle complicate da preeclampsia o neonati SGA.
description: Objective: to assess if the occurrence of adverse pregnancy outcome may be related to specific maternal cardiac parameters. 
Study design: women with twin pregnancies were prospectively submitted to serial maternal echocardiography (20-23 weeks; 26-29 weeks and 30-33 weeks). Cardiac findings were compared between patients with uneventful pregnancy outcome and those who developed one of the following complications: preeclampsia or gestational hypertension, SGA neonates or IUGR.
Results: A group of 28 twin gestations was obtained for analysis, including 8 complicated cases. At each visit cardiac output (CO) and stroke volume (SV) were significantly higher whereas total vascular resistance (TVR) was lower among uncomplicated vs complicated twin pregnancies. 
Conclusions: At longitudinal evaluation, maternal cardiac findings seem to be significantly different between uneventful twin pregnancies and those complicated.

description: The Sundarban Reserve Forest (SRF) of Bangladesh provides tourism services to local and international visitors. Indeed, tourism is one of the major ecosystem services that this biodiversity-rich mangrove forest provides. Through a convenient sampling technique, 421 tourist respondents were interviewed to assess their willingness to pay for the tourism services of the Sundarban, using the Zonal Travel Cost Method (ZTCM). The estimated annual economic contribution of tourism in the Sundarban mangroves to the Bangladesh economy is USD 53 million. The findings of this study showed that facilities for watching wildlife and walking inside the forest can increase the number of tourists in the SRF. The findings also show that the availability of information like forest maps, wildlife precautionary signs, and danger zones would increase the number of tourists as well. Thus, the government of Bangladesh should consider increasing visitor entry fees to fund improvements and to enhance the ecotourism potential of the Sundarban mangroves.

description: A planetary instability occurring at time $<100$ My after formation of the giant planets in our solar system can be responsible for some characteristics of the inner solar system. However, the actual influence of the instability on the terrestrial planet formation is not well understood. The simulations of terrestrial planet formation are very CPU-expensive, and this limits the exploration of different instability scenarios. To include the effects of the giant planets instability in the simulations of terrestrial planets formation in a feasible way, we approach the problem in two steps. First, we model and record an evolution of the giant planets that replicates the present outer solar system in the end. Then, we use that orbital record, properly interpolated, as the input for a second step to simulate its effects on the terrestrial planet formation. For this second step, we developed iSyMBA, a symplectic massive bodies algorithm, where ``i'' stands for interpolation. iSyMBA is a very useful code to accurately evaluate the effects of planetary instabilities on minor body reservoirs, while accounting for close encounters among massive objects. We provide a detailed description of how iSyMBA was developed and implemented to study terrestrial planet formation. Adapting iSyMBA for other problems that demand interpolation from previous simulations can be done following the method described here.

description: In \cite{confol} Y. Eliashberg and W. Thurston gave a definition of tight confoliations. We give an example of a tight confoliation $ξ$ on $T^3$ violating the Thurston-Bennequin inequalities. This answers a question from \cite{confol} negatively. Although the tightness of a confoliation does not imply the Thurston-Bennequin inequalities, it is still possible to prove restrictions on homotopy classes of plane fields which contain tight confoliations. The failure of the Thurston-Bennequin inequalities for tight confoliations is due to the presence of overtwisted stars. Overtwisted stars are particular configurations of Legendrian curves which bound a disc with finitely many punctures on the boundary. We prove that the Thurston-Bennequin inequalities hold for tight confoliations without overtwisted stars and that symplectically fillable confoliations do not admit overtwisted stars.

description: In this study, we present a new experiment in order to study the Lombard effect in telepresence robotics. In this experiment, one person talks with a robot controled remotely by someone in a different room. The remote pilot (R) is immersed in both environments, while the local interlocutor (L) interacts directly with the robot. In this context, the position of the noise source, in the remote or in the local room, may modify the subjects' voice adaptations. In order to study in details this phenomenon, we propose four particular conditions: no added noise, noise in room R heard only by R, virtual noise in room L heard only by R, and noise in room L heard by both R and L. We measured the variations of maximum intensity in order to quantify the Lombard effect. Our results show that there is indeed a modification of voice intensity in all noisy conditions. However, the amplitude of this modification varies depending on the condition.

description: Let n>2 and let M be an orientable complete finite volume hyperbolic n-manifold with (possibly empty) geodesic boundary having Riemannian volume vol(M) and simplicial volume ||M||. A celebrated result by Gromov and Thurston states that if M has empty boundary then the ratio between vol(M) and ||M|| is equal to v_n, where v_n is the volume of the regular ideal geodesic n-simplex in hyperbolic n-space. On the contrary, Jungreis and Kuessner proved that if the boundary of M is non-empty, then such a ratio is strictly less than v_n. We prove here that for every a>0 there exists k>0 (only depending on a and n) such that if the ratio between the volume of the boundary of M and the volume of M is less than k, then the ratio between vol(M) and ||M|| is greater than v_n-a. As a consequence we show that for every a>0 there exists a compact orientable hyperbolic n-manifold M with non-empty geodesic boundary such that the ratio between vol(M) and ||M|| is greater than v_n-a. Our argument also works in the case of empty boundary, thus providing a somewhat new proof of the proportionality principle for non-compact finite-volume hyperbolic n-manifolds without boundary.

description: We address the propagation of vortex beams with the circular Airy-Gaussian shape in a (2+1)-dimensional optical waveguide modeled by the fractional nonlinear Schrodinger equation. Systematic analysis of autofocusing of the beams reveals a strongly non-monotonous dependence of the peak intensity in the focal plane on the corresponding Levy index, with a strong maximum at alpha =1.4. Effects of the nonlinearity strength, the ratio of widths of the Airy and Gaussian factors in the input, as well as the beam vorticity, on the autofocusing dynamics are explored. In particular, multiple autofocusing events occur if the nonlinearity is strong enough. Under the action of the azimuthal modulational instability, an axisymmetric beam may split into a set of separating bright spots. In the case of strong fractality (for alpha close to 1), the nonlinear beam self-traps, after the first instance of autofocusing, into a breathing vortical quasi-soliton. Radiation forces induced by the beam field are considered too, and a capture position for a probe nanoparticle is thus identified.

Disaggregated short-term travel location prediction
Creators: name: Dong, Yanjie
Publisher: name: Imperial College London
Year: 2022

description: Disaggregated short-term location prediction aims at utilising historical spatial and temporal location data with current observed data to make predictions of next and future locations at the personal level. This type of prediction has many important applications, for example demand side traffic and travel management, epidemic control and prediction, mobile and targeted advertising, and location-based services such as ridesharing and micro-mobility. Existing studies have formulated the short-term location prediction as a sequence prediction problem and implemented methods such as Markov based models, trajectory matching method and recently deep learning-based methods. However, there are gaps in several areas including problem formulation, methodology and data platforms. In this thesis we first create an agent-based simulation platform to resolve the issue around the lack of ground truth data in the literature. The agent-based simulation combines London Travel Demand Survey (LTDS) and National Travel Survey (NTS) data to generate realistic activities, locations, and movement trajectories on a real road network in London, using a data-driven probabilistic approach. This modular platform can be further expanded to examine more scenarios or to be used as a generic tool to test location-based methodologies. Then we propose a spatial and temporal encoder-decoder deep learning model with attention and embedding layers (ST-EDAE) for short-term location prediction. Rather than the commonly used method of transforming location history as a sequence which is created based on minimum dwelling time requirements, we formulate the location history as time annotated locations into a fixed time intervals, which would allow the model to understand the notion of time and predict locations at specific time point in future. The model is tested both on simulated data from the agent-based simulation platform and on a real-world GPS dataset collected in Beijing. Results show that our model outperforms other popular methods in the literature for both next timestep location prediction and future location prediction. Prediction accuracy decreases as prediction horizon increases, but our model still performs the best across heterogeneous agent groups. Significant performance variations can be observed, with the model performing better on frequently visited than less visited locations. In addition, our model is shown to be able to learn a contextual representation of locations in the embedding layer, potentially opens up new research opportunities in data-driven location/land use classifications.

description: One of the challenges of telepresence robotics is to provide ubiquitous social-interpersonalimmersion. In order to achieve this, there is a need to understand and model the factors that wouldallow the users to control the transmission of their vocal productions, and to give them perception,proprioception and inter-proprioception of this control. This model for transferring sociallyembodied vocal distance should take into account all parameters involved in the social-interpersonaleffect of vocal productions, especially intensity. It should also integrate the background informationwhich is relevant for the speakers to express their intentions. In this paper, we present a firstexperiment for measuring, analyzing and modeling how human beings perceive the distance to aninterlocutor, depending on socio-affective variations in the vocal productions of this interlocutor.These results will be the reference for the models which will be implanted in our telepresence robot:Robair Social Touch.

Behaviour of some trace metals in sediments of the Fraser River delta-front, southwestern British Columbia
Creators: name: Grieve, David Austin
Publisher: name: University of British Columbia
Year: 2010

description: Co, Cu, Fe, Mn, Ni, Pb and Zn contents, both in total and partial extractions, have been determined for inter-tidal and foreslope surficial sediments of the Fraser River active delta-front. In conjunction with analysis of subsurface sediments and water and suspended sediment from the main channel, these data suggest controls on metal contents and distribution. An inverse relation between total metal contents and sand content of sediment is demonstrated in geographic distributions and correlation analysis of metal data. Relatively greater concentrations of metals in hydrous oxide phases and detrital minerals of the silt-plus-clay fraction account for this relationship. Trace metals in heavy minerals of the sand fraction partially negate the grain-size effect. Adsorbed metals are an insignificant quantity (excepting Mn) except in two samples from an area receiving effluent from the Iona Island sewage treatment plant. Variation of trace metal contents in short cores is generally related to transitions in sediment texture. Some metal may be mobilized and lost subsequent to burial, although this conclusion is contingent on the assumption that trace metal input to delta-front sediments is constant over time. One core collected near Iona Island, however, contains evidence that this assumption is not totally valid. Scavenging of Zn, and probably other trace metals, by newly-formed hydrous Fe (and possibly Mn) oxides takes place in brackish conditions within the main channel. In conjunction with physical processes which increase residence times of sediments in the estuarine portions of the river, this process accounts for removal of a sizeable fraction of dissolved metal. Desorption of trace metals occurs in the channel and in Georgia Strait, although probably to a somewhat lesser extent than the sorption process. In terms of metal contents and mechanisms of metal deposition, the Fraser delta-front is typical of nearshore sediments of low clay content. Trace metal sorption by various mechanisms, including that described here, accounts for retention of river-borne and waste metals in nearshore sediments.

description: We analyse the Anderson-Higgs mechanism of photon mass acquisition in a plasma and study the contribution to the mass from the orbital angular momentum acquired by a beam of photons when it crosses a spatially structured charge distribution. To this end we apply Proca-Maxwell equations in a static plasma with a particular spatial distribution of free charges, notably a plasma vortex, that is able to impose orbital angular momentum (OAM) onto light. In addition to the mass acquisition of the conventional Anderson-Higgs mechanism, we find that the photon acquires an additional mass from the OAM and that this mass reduces the Proca photon mass.

description: Cake filtration is a widely used solid-liquid separation process. However, the high flow resistance of the nanoporous filter cake lowers the efficiency of the process significantly. The structure and thus the permeability of the filter cakes depend on the compressive load acting on the particles, the particles size, and the agglomeration of the particles. The latter is determined by the particle charge and the ionic strength of the suspension, as described by the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory. In this paper, we propose a combined stochastic rotation dynamics (SRD) and molecular dynamics (MD) methodology to simulate the cake formation. The simulations give further insight into the dependency of the filter cakes' structure on the agglomeration of the particles, which cannot be accessed experimentally. The permeability, as investigated with lattice Boltzmann (LB) simulations of flow through the discretized cake, depends on the particle size and porosity, and thus on the agglomeration of the particles. Our results agree qualitatively with experimental data obtained from colloidal boehmite suspensions.

description: Instrumental genesis through interdisciplinary collaboration-reflections on the emergence of a visualisation framework for video annotation data XML This paper presents, discusses and reflects on the development of a visualization framework for the analysis of the temporal dynamics of audiovisual expressivity. The main focus lies on the instrumental genesis process (Rabardel 1995; Longchamp 2012)-a concept trying to express and analyze the co-evolution of instruments and the practices they make possible-underlying this development. It is described through the collaboration and communication processes between computer science scholars and humanities scholars in finding new ways of visualizing complex datasets for exploration and presentation in the realm of film-studies research. It draws on the outcome and concrete usage of the visualizations in publications and presentations of a research group, the AdAproject, that investigates the audiovisual rhetorics of affect in audiovisual media on the financial crisis (2007-). These film analyses are based on theoretical assumptions on the process of film-viewing, the relation of the viewer's perception and the temporally unfolding audiovisual images, and a methodical approach that draws on 'steps' in the research process such as segmentation, description and qualification, called eMAEX (Kappelhoff et al. 2011-2016) to reconstruct these experiential figurations (Bakels et al. 2020a, 2020b). The main focus of this paper is the process of iterative development of visualizations as interactive interfaces generated with the open-source software Advene, that were an integral part of the research process. In this regard, the timeline visualization is not only of interest for visual argumentation in (digital) humanities publications, but also for the creation of annotations as well as the exploration of this data. In the first part of the paper we describe this interdisciplinary collaboration as instrumental genesis on a general level-as an evolving and iterative process. In the second part we focus on the specific challenge of designing a visualization framework for the temporal dynamics of audiovisual aesthetics. Lastly we zoom out by reflecting on experiences and insights that might be of interest for the wider digital humanities community.

description: In this paper, we have selected a sample of 64 teraelectronvolt blazars, with redshift, from those classified in the fourth Fermi Large Area Telescope source catalog\footnote{\url{https://fermi.gsfc.nasa.gov/ssc/data/access/lat/8yr_catalog/}}. We have obtained the values of the relevant physical parameters by performing a log-parabolic fitting of the average-state multiwavelength spectral energy distributions. We estimate the range of the radiation zone parameters, such as the Doppler factor (${D}$), the magnetic field strength ($B$), the radiative zone radius ($R$) and the peak Lorentz factor (${γ_{\rm p}}$) of nonthermal electrons. Here, we show that (1) there is a strong linear positive correlation between the intrinsic synchrotron peak frequency and the intrinsic inverse Compton scattering (ICs) peak frequency among different types of blazars; (2) if radio bands are excluded, the spectral index of each band is negatively correlated with the intrinsic peak frequency; (3) there is a strong linear negative correlation between the curvature at the peak and the intrinsic peak frequency of the synchrotron bump, and a weak positive correlation between the curvature at the peak and the intrinsic peak frequency of the ICs bump; (4) there is a strong linear positive correlation between the intrinsic ICs peak luminosity and intrinsic $γ$-ray luminosity and between the intrinsic ICs peak frequency and peak Lorentz factor; (5) there is a strong negative linear correlation between $\rm log{\;B}$ and $\rm log{\;γ_{p}}$; and (6) there is no correlation between $\rm log{\;R}$ and $\rm log{\;γ_{p}}$.

description: We generate entangled states of an ensemble of 5*10^4 rubidium-87 atoms by optical quantum nondemolition measurement. The resonator-enhanced measurement leaves the atomic ensemble, prepared in a superposition of hyperfine clock levels, in a squeezed spin state. By comparing the resulting reduction of quantum projection noise (up to 8.8(8) dB) with the concomitant reduction of coherence, we demonstrate a clock input state with spectroscopic sensitivity 3.0(8) dB beyond the standard quantum limit.

description: In the 18th century in Paris, only two public theatres could officially perform comedies: the Com{é}die-Fran{\c c}aise, and the Com{é}die-Italienne. The latter was much less well known. By studying a century of accounting registers, we aim to learn more about its successful plays, its actors, musicians, set designers, and all the small trades necessary for its operation, its administration, logistics and finances. To this end, we employ a mass of untapped and unpublished resources, the 27,544 pages of 63 daily registers available at the Biblioth{è}que Nationale de France (BnF). And we take a decidedly fresh look at emerging forms of creation and changes in the entertainmenteconomy. We developed the crowdsourcing platform RECITAL to collect and index the data from theregisters, following an emerging trend in Digital Humanities. RECITAL is built upon the ScribeAPI framework and it offers a fully-fledged web application to classify the pages, annotate with marks and tags, transcribe the indexed marks and even to verify the previous transcripts. We also describe a multi-level data model and to develop a series of monitoring anddecision tools to support crowdsourced data management up to their definitive form.

description: The tau function corresponding to the affine ring of a certain plane algebraic curve, called (n,s)-curve, embedded in the universal Grassmann manifold is studied. It is neatly expressed by the multivariate sigma function. This expression is in turn used to prove fundamental properties on the series expansion of the sigma function established in a previous paper in a different method.

Unveiling the multi-level structure of midgap states in Sb-doped MoX$_2$ (X = S, Se, Te) monolayers

description: In this study, we use DFT calculations to investigate the electronic and structural properties of MoX$_2$ (X = S, Se, Te) monolayers doped with substitutional Sb atoms, with a central focus on the Sb(Mo) substitution. In MoS$_2$, we observe that this substitution is energetically favored under S rich conditions, where the S$_2$ gaseous phase is likely to be present. This result is compatible with a recent experimental observation in Sb-doped MoS$_2$ nanosheets grown by CVD. A similar behavior is found in MoSe$_2$, but in MoTe$_2$ the Sb(Mo) substitution is less likely to occur due to the possible absence of gaseous Te phases in experimental setups. In all cases, several impurity-induced states are found inside the band gap, with energies that span the entire gap. The Fermi energy is pinned a few tenths of eV above the top of the valence band, suggesting a predominant $p$-type behavior. The orbital nature of these states is investigated with projected and local density of states calculations, which reveal similarities to defect states induced by single Mo vacancies as well as their rehybridization with the $5s$ orbital from Sb. Additionally, we find that the band gap of the doped systems is increased in comparison with the pristine materials, in contrast with a previous calculation in Sb-doped MoS$_2$ that predicts a gap reduction with a different assignment of valence band and impurity levels. We discuss the similarities, discrepancies, and the limitations of both calculations. We also speculate possible reasons for the experimentally observed redshifts of the A and B excitons in the presence of the Sb dopants in MoS$_2$. We hope that these results spark future investigations on other aspects of the problem, particularly those concerning the effects of disorder and electron-hole interaction, and continue to reveal the potential of doped TMDCs for applications in optoelectronic devices.
