description: Qubits are physical, a quantum gate thus not only acts on the information carried by the qubit but also on its energy. What is then the corresponding flow of energy between the qubit and the controller that implements the gate? Here we exploit a superconducting platform to answer this question in the case of a quantum gate realized by a resonant drive field. During the gate, the superconducting qubit becomes entangled with the microwave drive pulse so that there is a quantum superposition between energy flows. We measure the energy change in the drive field conditioned on the outcome of a projective qubit measurement. We demonstrate that the drive's energy change associated with the measurement backaction can exceed by far the energy that can be extracted by the qubit. This can be understood by considering the qubit as a weak measurement apparatus of the driving field.

description: The purpose of this paper is to give a direct proof of an eigenfunction expansion formula for one-dimensional 2-state quantum walks, which is an analog of that for Sturm-Liouville operators due to Weyl, Stone, Titchmarsh and Kodaira. In the context of the theory of CMV matrix it had been already established by Gesztesy-Zinchenko. Our approach is restricted to the class of quantum walks mentioned above whereas it is direct and it gives some important properties of Green functions. The properties given here enable us to give a concrete formula for a positive-matrix-valued measure, which gives directly the spectral measure, in a simplest case of the so-called two-phase model.

description: In this study, we focused on the ultrasonic synthesis of titanium dioxide (TiO2) nanoparticles via a green chemistry process using Citrus limon (lemon) juice. XRD diffractograms and Raman spectroscopy revealed the anatase structure of TiO2, SEM analysis showed nanometric particle sizes, and FTIR spectroscopy confirmed the presence of the synthesized nanoparticles. The catalytic performance of the biosynthesised nanoparticles was evaluated for the synthesis of sulphur-substituted quinazolinone derivatives under UV irradiation. The final products were achieved in 6–8 h with good yields (79–91%).

description: Nonlinear spectroscopy is widely used for studying physical systems. Conventional nonlinear optical spectroscopy and magnetic resonance spectroscopy, which use classical probes such as electromagnetic waves, can only access certain types of correlations in a quantum system. The idea of quantum nonlinear spectroscopy was recently proposed to use quantum probes such as entangled photons to achieve sensitivities and resolutions beyond the classical limits. It is shown that quantum sensing can extract arbitrary types and orders of correlations in a quantum system by first quantum-entangling a sensor and the object and then measuring the sensor. Quantum sensing has been applied to achieve nuclear magnetic resonance (NMR) of single atoms and the second-order correlation spectroscopy has been adopted to enhance the spectral resolution. However, quantum nonlinear spectroscopy (i.e., the measurement of higher-order correlations) of single nuclear spins is still elusive. Here we demonstrate the extraction of fourth-order correlations of single nuclear spins that cannot be measured in conventional nonlinear spectroscopy, using sequential weak measurement via an atomic quantum sensor, namely, a nitrogen-vacancy center in diamond. We show that the quantum nonlinear spectroscopy provides fingerprint features to identify different types of objects, such as Gaussian noises, random-phased AC fields, and quantum spins, which would be indistinguishable in second-order correlations. The measured fourth-order correlation unambiguously differentiates a single nuclear spin and a random-phased AC field. This work constitutes an initial step toward the application of higher-order correlations to quantum sensing, to examining the quantum foundation (by, e.g., higher-order Leggett-Garg inequality), and to studying quantum many-body physics.

description: The calibration of the parameters of hyperelastic consitutive equations of elastomeric materials requires multi-axial mechanical test data. For this reason, planar biaxial tests have been used extensively in the literature. The drawback of the biaxial tensile test is that difficult to manage and gives raise to heterogeneous stress and strain fields. Noting that, a homogeneous stress-strain field allows for more precise determination of the mechanical properties of a sample. To this end, we present an alternative to biaxial testing, i.e. a novel test protocol that is consisting to deform a sample by coupling both the deformations of pure shear and of simple shear (or rectilinear shear). The sample is oriented in the plane of a special device, which is attached to a universal tensile testing machine. As a result, the stress-strain relations depend on the direction of stretching, i.e. Θ 2]0, π/2[ (angle of orientation of the sample in the device) and displacement U (or γ). We compute analytically the Cauchy stresses on the basis of assumption of homogeneous strain field in core region of the sample. We show that, these stresses are almost equal to that arising from the FE simulations. The homogeineity of fields in the core region allows us to relate the Cauchy stresses to the applied forces (under condition that the boundary value problems are well controlled allowing to obtain uniform stresses). So, the experimental data arising from this test could be suitable for identification or/and validation of hyperelastic models.

description: Via one-pot reaction of 2-naphthol, thiobarbituric acid and aldehyde in the presence of silica sulfuric acid (SSA) as a catalyst to synthesis benzochromenopyrimidines derivatives. Then we studied the reaction of benzochromenopyrimidines derivatives with bromoacetic acid to obtain benzo[5,6]chromeno[2,3-d]thiazolo[3,2-a]pyrimidine-11,13(10H,14H)-dione derivatives. Meanwhile, dichloroethane was reacted with 12-(4-fluorophenyl)-9-thioxo-9,10-dihydro-8H-benzo[5,6]chromeno[2,3-d]pyrimidin-11(12H)-one to form 14-(4-fluorophenyl)-10,11-dihydrobenzo[5,6]chromeno[2,3-d]thiazolo[3,2-a]pyrimidin-13(14H)-one. All new products structure was elucidated based on analytical and spectroscopic analyses. Anti-cancer activity of newly synthesized structures was investigated. Cancer cells (MDA-MB-231 and HepG2) were used to evaluate the anti-cancer activity of tested compounds using neutral red uptake assay. Treatment of MDA-MB-231 and HepG2 cells with tested compound 6h revealed more inhibitory influence after 48 h. The expression levels of BCL2, BAX, Caspase3, Survivin and P53 genes were investigated using QRT-PCR. This study exhibited that compound 6h revealed significant pro-apoptotic effect via down regulation of BCL2 and Survivin genes and up-regulation of BAX, Caspase3 and P53 genes when treated with MDA-MB-231 and HepG2 cells as compared to control values. The biological studies of these compounds were proved through molecular docking studies with human cyclin-dependent kinase 2 (PDB code: 2A4L) and compound 6h showed low binding energy and shortage bond length with different amino acids. Noteworthy, the tested compound 6h exhibited the most pronounced effect in this respect.

description: The classical phase retrieval problem arises in contexts ranging from speech recognition to x-ray crystallography and quantum state tomography. The generalization to matrix frames is natural in the sense that it corresponds to quantum tomography of impure states. We provide computable global stability bounds for the quasi-linear analysis map $β$ and a path forward for understanding related problems in terms of the differential geometry of key spaces. In particular, we manifest a Whitney stratification of the positive semidefinite matrices of low rank which allows us to ``stratify'' the computation of the global stability bound. We show that for the impure state case no such global stability bounds can be obtained for the non-linear analysis map $α$ with respect to certain natural distance metrics. Finally, our computation of the global lower Lipschitz constant for the $β$ analysis map provides novel conditions for a frame to be generalized phase retrievable.

description: Theoretical prediction of Curie temperature (TC) is of vital importance for designing the spintronic devices in two-dimensional (2D) ferromagnetic materials. Herein, based on the extensive investigation of Monte Carlo simulations, we summary and propose an improved method to estimate TC more precisely, which includes the different contributions of multiple near-neighbor interactions. Taking monolayer CrI3 as an example, the trends of TC with biaxial strain are investigated via Monte Carlo simulations, mean-field formulas and our method. Besides, our method is not only accurate and convenient to predicting the TC in 2D ferromagnetic honeycomb lattice CrI3 but it can be extended for predicting the TC of other 2D lattices. Our work paves the way to accelerate the prediction and discovery of novel 2D ferromagnets for spintronic applications.

description: Oxygen ($^{16}$O) ions are planned to be injected at the Large Hadron Collider (LHC) in its next runs, and a day of physics run is anticipated for O+O collisions at $\sqrt{s_{\rm{NN}}}$ = 7 TeV. As the system size of O+O collisions has the final state multiplicity overlap with those produced in pp, p+Pb and Pb+Pb collisions, the study of global properties in O+O collisions may provide a deeper insight into the heavy-ion-like behavior observed in small collision systems and its similarities/differences with a larger system like Pb+Pb collisions. In the present work, we report the predictions for global properties in O+O collisions at $\sqrt{s_{\rm{NN}}}$ = 7 TeV using a multi-phase transport model (AMPT). We report the mid-rapidity charged-particle multiplicity, transverse mass, Bjorken energy density, pseudo-rapidity distributions, squared speed of sound, transverse momentum ($p_{\rm T}$) spectra, the kinetic freeze-out parameters, and $p_{\rm T}$-differential particle ratio as a function of collision centrality. Further, we have studied the transverse momentum-dependent elliptic flow of charged particles. The results are shown for Woods-Saxon and harmonic oscillator nuclear density profiles. In addition, we have compared the results with an $α$-clustered structure incorporated inside the oxygen nucleus. Average charged-particle multiplicity and the Bjorken energy density show a significant increase in most central collisions for the harmonic oscillator density profile, while other global properties show less dependence on the density profiles considered in this work. The results from the $α$-clustered structure incorporated inside the oxygen nucleus show similar initial energy density and final charged-particle multiplicity as observed for the harmonic oscillator density profile.

description: BACKGROUND: Preterm birth (PTB), or birth before 37 weeks of gestation, is the leading cause of newborn death worldwide. PTB is a critical area of scientific study not only due to its worldwide toll on human lives and economies, but also due to our limited understanding of its pathogenesis and, therefore, its prevention. This systematic review and meta-analysis synthesizes the landscape of PTB transcriptomics research to further our understanding of the genes and pathways involved in PTB subtypes. METHODS: We evaluated published genome-wide pregnancy studies across gestational tissues and pathologies, including those that focus on PTB, by performing a targeted PubMed MeSH search and systematically reviewing all relevant studies. RESULTS: Our search yielded 2,361 studies on gestational tissues including placenta, decidua, myometrium, maternal blood, cervix, fetal membranes (chorion and amnion), umbilical cord, fetal blood, and basal plate. Selecting only those original research studies that measured transcription on a genome-wide scale and reported lists of expressed genetic elements identified 93 gene expression, 21 microRNA, and 20 methylation studies. Although 30 % of all PTB cases are due to medical indications, 76 % of the preterm studies focused on them. In contrast, only 18 % of the preterm studies focused on spontaneous onset of labor, which is responsible for 45 % of all PTB cases. Furthermore, only 23 of the 10,993 unique genetic elements reported to be transcriptionally active were recovered 10 or more times in these 134 studies. Meta-analysis of the 93 gene expression studies across 9 distinct gestational tissues and 29 clinical phenotypes showed limited overlap of genes identified as differentially expressed across studies. CONCLUSIONS: Overall, profiles of differentially expressed genes were highly heterogeneous both between as well as within clinical subtypes and tissues as well as between studies of the same clinical subtype and tissue. These results suggest that large gaps still exist in the transcriptomic study of specific clinical subtypes as well in the generation of the transcriptional profile of well-studied clinical subtypes; understanding the complex landscape of prematurity will require large-scale, systematic genome-wide analyses of human gestational tissues on both understudied and well-studied subtypes alike.

description: Now, in this paper, we report the successful fabrication of MNPs-bis(2-hydroxyethyl)-guanidine-Ni nanocatalyst and study its catalytic behavior for the synthesis of pyrano[2,3-c]pyrazoles and highly functionalized piperidines. The Structure of the as-fabricated MNPs-guanidine-bis(ethanol)-Ni nanomaterial was fully characterized by advanced microscopic and spectroscopic methods, such as FT-IR, SEM, TEM, EDX, TGA, VSM, XRD and ICP-OES. With aryl aldehydes, ethyl acetoacetate, and aniline or malononitrile and hydrazine hydrate as the reactive species, the created MNPs-bis(2-hydroxyethyl)-guanidine-Ni catalytic agent acts as a promising candidate to deliver numerous pharmaceutically relevant highly functionalized piperidines and pyrano[2,3-c]pyrazoles scaffolds. The developed methodology comes with a host of advantageous features, such as gentle reaction conditions, a broad substrate range, great product yields, and a brief reaction time. Additionally, the Ni nanocatalyst could be easily recovered by a simple magnetic separation and recycled at least 8 times without deterioration in catalytic activity.

description: Over the past few years bulk pyrochlore iridates of the form $A_2$Ir$_2$O$_7$ (where $A$ is a rare earth element, Ir is iridium, and O is oxygen) have been studied as model systems for investigating the interplay of electronic correlations and strong spin-orbit coupling, particularly with the aim of finding correlation-driven topological phases. In this work, we use cellular dynamical mean field theory (CDMFT) to study effects of electronic correlations beyond Hartree-Fock theory in thin films of pyrochlore irradiates grown along the $[111]$ direction. We focus on the bilayer and trilayer systems, and compute the phase diagrams of these systems as a function of electron-electron interaction strength, which is modeled by an on-site Hubbard interaction. By evaluating the $Z_2$ invariant and Chern number using formulas based on the single-particle Green's function and the quasi-particle effective Hamiltonian, we show that on-site correlations can drive an interaction-induced topological phase transition, turning a time-reversal invariant topological insulator and a nearly flat band metal to a correlated Chern insulator (CI) in bilayer and trilayer systems, respectively. By comparing with the Hartree-Fock results, the CDMFT results show that quantum fluctuations enhance the robustness of the interaction-driven CI phase in the thin films. Furthermore, our numerical analysis of the quasiparticle spectrum reveals that the topological phases we find in our many-body calculations are adiabatically connected to those in the single-particle picture.

description: The segregation of cells with distinct regional identity underlies formation of a sharp border, which in some tissues serves to organise a boundary signaling centre. It is unclear whether or how border sharpness is coordinated with induction of boundary-specific gene expression. We show that forward signaling of EphA4 is required for border sharpening and induction of boundary cells in the zebrafish hindbrain, which we find both require kinase-dependent signaling, with a lesser input of PDZ domain-dependent signaling. We find that boundary-specific gene expression is regulated by myosin II phosphorylation, which increases actomyosin contraction downstream of EphA4 signaling. Myosin phosphorylation leads to nuclear translocation of Taz, which together with Tead1a is required for boundary marker expression. Since actomyosin contraction maintains sharp borders, there is direct coupling of border sharpness to boundary cell induction that ensures correct organisation of signaling centres.

description: Background and purpose: The delineation of the gross tumor volume (GTV) is a critical step for radiation therapy treatment planning. The delineation procedure is typically performed manually which exposes two major issues: cost and reproducibility. Delineation is a time-consuming process that is subject to inter- and intra-observer variability. While methods have been proposed to predict GTV contours, typical approaches ignore variability and therefore fail to utilize the valuable confidence information offered by multiple contours. Materials and methods: In this work we propose an automatic GTV contouring method for soft-tissue sarcomas from X-ray computed tomography (CT) images, using deep learning by integrating inter- and intra-observer variability in the learned model. Sixty-eight patients with soft tissue and bone sarcomas were considered in this evaluation, all underwent pre-operative CT imaging used to perform GTV delineation. Four radiation oncologists and radiologists performed three contouring trials each for all patients. We quantify variability by defining confidence levels based on the frequency of inclusion of a given voxel into the GTV and use a deep convolutional neural network to learn GTV confidence maps. Results: Results were compared to confidence maps from the four readers as well as ground-truth consensus contours established jointly by all readers. The resulting continuous Dice score between predicted and true confidence maps was 87% and the Hausdorff distance was 14 mm. Conclusion: Results demonstrate the ability of the proposed method to predict accurate contours while utilizing variability and as such it can be used to improve clinical workflow.

description: Open-access microcavities are emerging as a new approach to confine and engineer light at mode volumes down to the $λ^3$ regime. They offer direct access to a highly confined electromagnetic field while maintaining tunability of the system and flexibility for coupling to a range of matter systems. This article presents a study of coupled cavities, for which the substrates are produced using Focused Ion Beam milling. Based on experimental and theoretical investigation the engineering of the coupling between two microcavities with radius of curvature of \SI{6}{\micro\meter} is demonstrated. Details are provided by studying the evolution of spectral, spatial and polarisation properties through the transition from isolated to coupled cavities. Normal mode splittings up to 20 meV are observed for total mode volumes around $10 \times λ^3$. This work is of importance for future development of lab-on-a-chip sensors and photonic open-access devices ranging from polariton systems to quantum simulators.

description: Crop and animal production generate a high level of organic waste that causes negative effects on the environment and communities. The use of composting processes can improve the quality of these biowastes. Additionally, the application of technologies such as telemetry and remote sensors, allows optimizing the transformation of organic matter in a more controlled and efficient way. The city of Fusagasugá is well known in agriculture. However, it lacks sustainable management of the organic waste system. In this study, after a three-dimensional electromechanical design, a prototype reactor to compost agricultural wastes of Fusagasuga municipality will provide. The capacity of this prototype reactor is considered to be 20 litres. In order to control temperature and humidity of biowastes in different working conditions, it is used A PI controller with 3 temperature and a humidity sensors. With these sensors the compost materials temperature and humidity will remain at 65 °C and 55–60%. By using a special form of temperature sensor placement, the time to oxygenate the compost materials will be found. Furthermore, this system is integrated by a Human-Machine Interface (HMI), which allows the supervision and manipulation from a remote access user.

description: The next generation of wide-field cosmic microwave background (CMB) surveys are uniquely poised to open a new window for time-domain astronomy in the millimeter band. Here we explore the discovery phase space for extragalactic transients with near-term and future CMB experiments to characterize the expected population. We use existing millimeter-band light curves of known transients (gamma-ray bursts, tidal disruption events, fast blue optical transients, neutron star mergers) and theoretical models, in conjunction with known and estimated volumetric rates. Using Monte Carlo simulations of various CMB survey designs (area, cadence, depth, duration) we estimate the detection rates and the resulting light curve characteristics. We find that existing and near-term surveys will find tens to hundreds of long-duration gamma-ray bursts (LGRBs), driven primarily by detections of the reverse shock emission, and including off-axis LGRBs. Next-generation experiments (CMB-S4, CMB-HD) will find tens of fast blue optical transients (FBOTs) in the nearby universe and will detect a few tidal disruption events. CMB-HD will additionally detect a small number of short gamma-ray bursts, where these will be discovered within the detection volume of next generation gravitational wave experiments like Cosmic Explorer.

description: A facile approach for the synthesis of bioactive acridinedione analogs using dimedone, aryl aldehydes, and ammonium acetate was developed using caffeine hydrogen sulfate catalyst in ethanol and water (2:1) solvent mixture at room temperature. The significant advantages of this procedure are efficient and simple method, ambient conditions, short reaction time (5–30 min), simple workup, easily recoverable catalyst, broad substrate scope and good yields (45–80%). Being water soluble, the catalyst was easily recovered by water and reused up to 4 runs. Moreover, the antimicrobial profile of synthesized derivatives was performed against different bacterial and fungal strains using broth microdilution method. Most of the synthesized derivatives exhibited significant activity against bacterial and fungal strains compared to standard. Compounds 4e (31.25 µg/mL and 31.25 µg/mL) and 4g (31.25 µg/mL and 62.5 µg/mL) were found the most active against E. coli. and S. aureus respectively with good MIC values. Compound 4f and 4j displayed the highest antifungal activity against A. niger with 31.25 µg/mL MIC value.
Comparison between two and three dimensional Rayleigh-Bénard convection

description: Two dimensional (2D) and three dimensional (3D) Rayleigh-Bénard convection is compared using results from direct numerical simulations and prior experiments. The explored phase diagrams for both cases are reviewed. The differences and similarities between 2D and 3D are studied using Nu(Ra) for Pr = 4.38 and Pr = 0.7 and Nu(Pr) for Ra up to $10^8$. In the Nu(Ra) scaling at higher Pr, 2D and 3D are very similar; differing only by a constant factor up to $\text{Ra} = 10^{10}$. In contrast, the difference is large at lower Pr, due to the strong roll state dependence of Nu in 2D. The behaviour of Nu(Pr) is similar in 2D and 3D at large Pr. However, it differs significantly around Pr = 1. The Reynolds number values are consistently higher in 2D and additionally converge at large Pr. Finally, the thermal boundary layer profiles are compared in 2D and 3D.

description: Review of the book “Saccheggio in Mesopotamia. Il Museo di Baghdad dalla nascita dell'Iraq a oggi“ written by Frederick Mario Fales and published by Forum Editrice Universitaria Udinese.
Frederick Mario Fales, Professor of Ancient Near Eastern History at the University of Udine, has built a monumental work that goes well beyond the wide time span indicated in the subtitle (From the birth of Iraq to today). The amount of information available and materials that Fales uses in the course of his investigation is literally endless, a "jungle of data" to say it with the author, it varies both in type and nature and in communicative support, and therefore in language, used.

description: Unsupervised domain adaptation (UDA) for semantic segmentation has been well-studied in recent years. However, most existing works largely neglect the local regional consistency across different domains and are less robust to changes in outdoor environments. In this paper, we propose a novel and fully end-to-end trainable approach, called regional contrastive consistency regularization (RCCR) for domain adaptive semantic segmentation. Our core idea is to pull the similar regional features extracted from the same location of different images, i.e., the original image and augmented image, to be closer, and meanwhile push the features from the different locations of the two images to be separated. We innovatively propose a region-wise contrastive loss with two sampling strategies to realize effective regional consistency. Besides, we present momentum projection heads, where the teacher projection head is the exponential moving average of the student. Finally, a memory bank mechanism is designed to learn more robust and stable region-wise features under varying environments. Extensive experiments on two common UDA benchmarks, i.e., GTAV to Cityscapes and SYNTHIA to Cityscapes, demonstrate that our approach outperforms the state-of-the-art methods.

Entropic tests of multipartite nonlocality and state-independent contextuality

description: We introduce a multipartite extension of an information-theoretic distance first introduced in [Nature 341, 119 (1989)]. We use this new distance to derive entropic tests of multipartite nonlocality for three and for an arbitrary even number of qubits as well as a test of state-independent contextuality. In addition, we re-derive the tripartite Mermin inequality and a state-independent non-contextuality inequality by Cabello [Phys. Rev. Lett. 101, 210401 (2008)]. This suggests that the information-theoretic distance approach to multipartite nonlocality and state-independent contextuality can provide a more general treatment of nonclassical correlations than the orthodox approach based on correlation functions.
