description: We demonstrate a new method of cavity-enhanced non-destructive detection of atoms for a strontium optical lattice clock. The detection scheme is shown to be linear in atom number up to at least 10,000 atoms, to reject technical noise sources, to achieve signal to noise ratio close to the photon shot noise limit, to provide spatially uniform atom-cavity coupling, and to minimize inhomogeneous ac Stark shifts. These features enable detection of atoms with minimal perturbation to the atomic state, a critical step towards realizing an ultra-high-stability, quantum-enhanced optical lattice clock.

description: This article examines the preferences revealed by three non-hypothetical experiments. We found that WTP estimates from the choice experiment are the highest, followed by that of contingent valuation methods, and then experimental auctions. Our results also suggest that the discrepancies among estimates from the valuation methods can come from the heterogeneity of respondents’ price bargaining aggressiveness.

description: According to the nonequilibrium work relations, path-ensembles generated by irreversible processes in which a system is driven out of equilibrium according to a predetermined protocol may be used to compute equilibrium free energy differences and expectation values. Estimation has previously been improved by considering data collected from the reverse process, which starts in equilibrium in the final thermodynamic state of the forward process and is driven according to the time-reversed protocol. Here, we develop a theoretically rigorous statistical estimator for nonequilibrium path-ensemble averages specialized for symmetric protocols, in which forward and reverse processes are identical. The estimator is tested with a number of model systems: a symmetric 1D potential, an asymmetric 1D potential, the unfolding of deca-alanine, separating a host-guest system, and translocating a potassium ion through a gramicidin A ion channel. When reconstructing free energies using data from symmetric protocols, the new estimator outperforms existing rigorous unidirectional and bidirectional estimators, converging more quickly and resulting in smaller error. However, in most cases, using the bidirectional estimator with data from a forward and reverse pair of asymmetric protocols outperforms the corresponding symmetric protocol and estimator with the same amount of simulation time. Hence, the new estimator is only recommended when the bidirectional estimator is not feasible or is expected to perform poorly. The symmetric estimator has similar performance to a unidirectional protocol of half the length and twice the number of trajectories.

We show that when the potential assumes specific form, there are models which support stable global defects for D arbitrary. We also show how to find first-order differential equations that solve the equations of motion, and how to solve models in D dimensions via soluble problems in D=1. We illustrate the procedure examining specific models and finding explicit solutions.

description: Background: Tumor mutational burden (TMB) is a promising biomarker for stratifying patient subpopulation who would benefit from immune checkpoint blockade (ICB) therapies. However, TMB measurements between different methods are poorly comparable. Furthermore, the effect of low tumor content on TMB estimation has never been systematically investigated. A standardized data analysis pipeline for TMB calculation and reporting for samples with variable tumor content is needed. Design: We built a linear model to correlate TMB estimated using whole exome sequencing (wesTMB) with targeted panel sequencing (psTMB). We further produced 12 series of reference DNA samples derived from tumor-normal paired cell lines with variable TMB in the parental tumor cell lines. Each tumor cell line was mixed with its matched normal at 0% (control), 1%, 2%, 5%, and 10% mass-to-mass ratio to mimic the variable tumor content in clinical setup. The reference standards were distributed to five vendors. This comparative test was intended to challenge both the quantitative coherence of TMB measurement by different vendors and the validity of our in-silico model. Results: Simulated psTMB and wesTMB of standard samples fitted the linear model trained by TCGA data. Dilution simulation demonstrated the decisive role of low-VAF variations to TMB detection in low tumor content samples. For 5% and 10% diluted reference standards, variants calling were reproducible and could be confirmed compared to parental cell lines. Futhermore, psTMB and wesTMB correlated closely for TMB-high patient stratification based on the linear model. Conclusions: We developed a linear model to establish the quantitative correlation between wesTMB and psTMB. A set of DNA reference standards was produced in aid to standardize TMB measurements in samples with low tumor content across different targeted sequencing panels. This study is a significant contribution aiming to harmonize TMB estimation and extend its future application in clinical samples with low tumor content.

description: Gate-based quantum computations represent an essential to realize near-term quantum computer architectures. A gate-model quantum neural network (QNN) is a QNN implemented on a gate-model quantum computer, realized via a set of unitaries with associated gate parameters. Here, we define a training optimization procedure for gate-model QNNs. By deriving the environmental attributes of the gate-model quantum network, we prove the constraint-based learning models. We show that the optimal learning procedures are different if side information is available in different directions, and if side information is accessible about the previous running sequences of the gate-model QNN. The results are particularly convenient for gate-model quantum computer implementations.

description: We find sharp upper and lower bounds for the degree of an algebraic number in terms of the $Q$-dimension of the space spanned by its conjugates. For all but seven nonnegative integers $n$ the largest degree of an algebraic number whose conjugates span a vector space of dimension $n$ is equal to $2^n n!$. The proof, which covers also the seven exceptional cases, uses a result of Feit on the maximal order of finite subgroups of $GL_n(Q)$; this result depends on the classification of finite simple groups. In particular, we construct an algebraic number of degree 1152 whose conjugates span a vector space of dimension only 4. We extend our results in two directions. We consider the problem when $Q$ is replaced by an arbitrary field, and prove some general results. In particular, we again obtain sharp bounds when the ground field is a finite field, or a cyclotomic extension of $Q$. Also, we look at a multiplicative version of the problem by considering the analogous rank problem for the multiplicative group generated by the conjugates of an algebraic number.

description: Kingman's model describes the evolution of a one-locus haploid population of infinite size and discrete generations under the competition of selection and mutation. A random generalisation has been made in a previous paper which assumes all mutation probabilities to be i.i.d.. The weak convergence of fitness distributions to a globally stable equilibrium for any initial distribution was proved. A condensation occurs if almost surely a positive proportion of the population travels to and condensates on the largest fitness value due to the dominance of selection over mutation. A criterion of condensation was given which relies on the equilibrium whose explicit expression is however unknown. This paper tackles these problems based on the discovery of a matrix representation of the random model. An explicit expression of the equilibrium is obtained and the key quantity in the condensation criterion can be estimated. Moreover we examine how the design of randomness in Kingman's model affects the fitness level of the equilibrium by comparisons between different models. The discovered facts are conjectured to hold in other more sophisticated models.

description: Compelling evidence has suggested the pivotal role of immune cells in carcinogenesis and metastasis in pancreatic cancer. Interrogation on the cell diversity is essential to delineate the tumor microenvironment and the cross-talks between immune cells and tumor. In the current study, we systemically profile single-cell transcriptomes of pancreatic cancer, providing a comprehensive single-cell map of the Pancreatic cancer microenvironment to date. Interestingly, cancer-associated fibroblasts (CAFs) display previously unidentified heterogeneity containing 5 subpopulations with different gene signatures, potentially leading to varied degrees of tissue fibrosis. Moreover, we describe the transcriptional regulatory network of CAFs and reveal two transcription factor which play a decisive role in CAFs function. Our analyses highlight the connection between infiltrated exhausted T cells and CAF by different chemokine and chemokine receptor pairs and provide novel insights into the cellular crosstalk in pancreatic cancer microenvironment at single-cell resolution. Results from this study will further our understanding of immune landscape in pancreatic cancer with implications for therapeutic development.

description: In secret sharing protocols, a secret is to be distributed among several partners so that leaving out any number of them, the rest do not have the complete information. Strong multiqubit correlations in the state by which secret sharing is carried out, had been proposed as a criterion for security of such protocols against individual attacks by an eavesdropper. However we show that states with weak multiqubit correlations can also be used for secure secret sharing. That our state has weak multiqubit correlations, is shown from the perspective of violation of local realism, and also by showing that its higher order correlations are described by lower ones. We then present a unified criterion for security of secret sharing in terms of violation of local realism, which works when the secret sharing state is the Greenberger-Horne-Zeilinger state (with strong multiqubit correlations), as well as states of a different class (with weak multiqubit correlations).

description: We have calculated the surface stress induced on adsorption of c(2x2) overlayers of O and C, using first principles electronic structure calculations based on density functional theory within the local density approximation(LDA) and non-local pseudopotentials. Most remarkable result is found in the case of the C overlayer which introduces a large compressive stress, while that on clean Ni(100) and that in the presence of the O overlayer are found to be tensile and smaller in comparison. We find a correlation between the height of the C overlayer and the resulting clock reconstruction of Ni(100) but no specific relationship between surface stress and surface reconstruction. We discuss our results in the context of experimental data, and insights from electronic structure calculations.

description: A two dimensional numerical model in the axisymmetric approximation that describes the flow structure in the magnetosphere of the white dwarf in the EX Hya system has been developed. Results of simulations show that the accretion in EX Hya proceeds via accretion columns, that are not closed and have curtain-like shapes. The thickness of the accretion curtains depends only weakly on the thickness of the accretion disk. This thickness developed in the simulations does not agree with observations. It is concluded that the main reason for the formation of thick accretion curtains in the used model is the assumption that the magnetic field penetrates fully into the plasma of the disk. An analysis based on simple estimates shows that a diamagnetic disk that fully or partially shields the magnetic field of the star may be a more attractive explanation for the observed features of the accretion in EX Hya.

description: Background: Chromosomal anomalies have been revealed to be one of the main causes leading to miscarriage. Among various methods, NGS has recently been validated to be an applicable approach in detecting aberrations occurring in chromosomes. Hereby, we evaluate the application of BGISEQ-500 based NGS in chromosomal aberration detection in miscarried fetus.Methods: Miscarriage samples were collected from Inner Mongolia maternal and child health hospital. Those samples were further analyzed with two independent methods, FISH and low coverage whole genome sequencing on the BGISEQ-500 high-throughput platform. The performance of the platform was assessed by comparing to FISH results.Results: In 595 miscarried specimens, BGISEQ-500 based NGS revealed that 144 (24.2%) cases carried chromosomal abnormalities, of which a subset of 137 (23.0%) cases were detected as aneuploidies, 2 (0.3%) cases as mosaicisms and 5 (0.8%) cases as CNVs (≥5Mb). Our NGS method showed a high consistency with FISH and could also detect aneuploidies beyond the FISH probes panel and CNVs.Conclusions: Our strategy is a reliable method in detecting chromosomal aberrations, including chromosome aneuploidies, mosaicisms and CNVs (≥5Mb), in aborted tissues.

description: We present a simple model system with four hard disks moving in a circular region for which free energy landscapes can be directly calculated and visualized in two and three dimensions. We construct several energy landscapes for our system and explore the strengths and limitations of each in terms of understanding system dynamics, in particular the relationship between state transitions and free energy barriers. We also demonstrate the importance of distinguishing between system dynamics in real space and those in landscape coordinates, and show that care must be taken to appropriately combine dynamics with barrier properties to understand the transition rates. This simple model provides an intuitive way to understand free energy landscapes, and illustrates the benefits free energy landscapes can have over potential energy landscapes.

description: We calculate resummed perturbative predictions for gaps-between-jets processes and compare to HERA data. Our calculation of this non-global observable needs to include the effects of primary gluon emission (global logarithms) and secondary gluon emission (non-global logarithms) to be correct at the leading logarithm (LL) level. We include primary emission by calculating anomalous dimension matrices for the geometry of the specific event definitions and estimate the effect of non-global logarithms in the large $N_c$ limit. The resulting predictions for energy flow observables are consistent with experimental data.

description: In this paper, we consider several questions emerging from the Beurling-Lax-Halmos Theorem, which characterizes the shift-invariant subspaces of vector-valued Hardy spaces. The Beurling-Lax-Halmos Theorem states that a backward shift-invariant subspace is a model space $\mathcal{H}(Δ) \equiv H_E^2 \ominus ΔH_{E}^2$, for some inner function $Δ$. Our first question calls for a description of the set $F$ in $H_E^2$ such that $\mathcal{H}(Δ)=E_F^*$, where $E_F^*$ denotes the smallest backward shift-invariant subspace containing the set $F$. In our pursuit of a general solution to this question, we are naturally led to take into account a canonical decomposition of operator-valued strong $L^2$-functions. Next, we ask: Is every shift-invariant subspace the kernel of a (possibly unbounded) Hankel operator? As we know, the kernel of a Hankel operator is shift-invariant, so the above question is equivalent to seeking a solution to the equation $\ker H_Φ^*=ΔH_{E^{\prime}}^2$, where $Δ$ is an inner function satisfying $Δ^* Δ=I_{E^{\prime}}$ almost everywhere on the unit circle $\mathbb{T}$ and $H_Φ$ denotes the Hankel operator with symbol $Φ$. Consideration of the above question on the structure of shift-invariant subspaces leads us to study and coin a new notion of "Beurling degree" for an inner function. We then establish a deep connection between the spectral multiplicity of the model operator and the Beurling degree of the corresponding characteristic function. At the same time, we consider the notion of meromorphic pseudo-continuations of bounded type for operator-valued functions, and then use this notion to study the spectral multiplicity of model operators (truncated backward shifts) between separable complex Hilbert spaces. In particular, we consider the multiplicity-free case.

Cinema as an Apparatus for Homemaking: Gender Roles from Post-war Neorealism to the Contemporary Italian Scene

description: The paper presents how the representation of the categories of urban, domestic, individual and collective in Italian Neorealist and New Migrant Cinema enhances a new understanding of migrant and gender subjectivities. Its scope is double-fold: firstly, it draws upon the situation of the gender roles of migrants in post-war neorealist films, and, secondly, it addresses the ways in which contemporary Italian films dealing with contemporary migrants in Rome relate to the post-war neorealist scene. The main objective is to present how cinema, in both cases, functions as an aesthetic apparatus that mediates the homemaking mechanisms of migrants. Special attention is paid to how gender roles contribute to the mise-en-scène of such apparatuses, and to how cinema as an aesthetic apparatus can address and reconstruct the experience of migrant architectures, and the homemaking mechanisms of migrants. The way gender and migrant roles were conceived in Italian Neorealist and New Migrant Cinema was based on the intention to address the fears and anxieties of migrant architecture and homemaking and to challenge the stereotypes that characterise them. In Italian Neorealist cinema, the roles of borgatari and women function as devices of reconceptualization of Italy’s identity, providing a fertile terrain to reflect on the intersections between migration studies, urban studies and gender studies. A point of departure is the remark that, in contemporary Italian cinema – as Aine O’Healy remarks, in Migrant Anxieties: Italian Cinema in a Transnational Frame – one can discern some similarities in “the ways in which films featuring migrants remap the national territory” with neorealist films. The reconfiguration of national narratives that is achieved in the cases of Neorealist and New Migrant cinema in Italy is closely related to the formation of new subjectivities, and to the transformation of the anxieties accompanying migrant architecture into apparatuses of creative processes. Converting the anxieties of migrant architecture and homemaking into their very terrain of exploration, the films of Neorealist and New Migrant cinema in Italy reconceptualize not only the idea of community, but the way it is associated with the reconfiguration of national narratives in cinema as well.

description: We revise the bounds on heavy sterile neutrinos, especially in the case of their mixing with muon neutrinos in the charged current. We summarize the present experimental limits, and we reanalyze the existing data from the accelerator neutrino experiments and from Super-Kamiokande to set new bounds on a heavy sterile neutrino in the range of masses from 8 MeV to 390 MeV. We also discuss how the future accelerator neutrino experiments can improve the present limits.

description: Isomer search or molecule enumeration refers to the problem of finding all the isomers for a given molecule. Many classical search methods have been developed in order to tackle this problem. However, the availability of quantum computing architectures has given us the opportunity to address this problem with new (quantum) techniques. This paper describes a quantum isomer search procedure for determining all the structural isomers of alkanes. We first formulate the structural isomer search problem as a quadratic unconstrained binary optimization (QUBO) problem. The QUBO formulation is for general use on either annealing or gate-based quantum computers. We use the D-Wave quantum annealer to enumerate all structural isomers of all alkanes with fewer carbon atoms (n < 10) than Decane (C10H22). The number of isomer solutions increases with the number of carbon atoms. We find that the sampling time needed to identify all solutions scales linearly with the number of carbon atoms in the alkane. We probe the problem further by employing reverse annealing as well as a perturbed QUBO Hamiltonian and find that the combination of these two methods significantly reduces the number of samples required to find all isomers.

description: The nuclear spin-mediated quantum relaxation of ensembles of tunneling magnetic molecules causes a 'hole' to appear in the distribution of internal fields in the system. The form of this hole, and its time evolution, are studied using Monte Carlo simulations. It is shown that the line-shape of the tunneling hole in a weakly polarised sample must have a Lorentzian lineshape- the short-time half-width $ξ_o$ in all experiments done so far should be $\sim E_0$, the half-width of the nuclear spin multiplet. After a time $τ_o$, the single molecule tunneling relaxation time, the hole width begins to increase rapidly. In initially polarised samples the disintegration of resonant tunneling surfaces is found to be very fast.

description: Chinese sillago (Sillago sinica), belonging to Sillaginidae, is commonly known as sand whitings or sand borers, which inhabits in seawaters from Bohai Sea to Xiamen in China, as well as Gwangyang, Korea. In recent years, morphological description, phylogenetic analysis of DNA barcoding and mitochondrial genome analysis have been conducted on Chinese sillago, and the phylogenetic relationship of the genus Sillago has been reconstructed. A draft genome assembly for Chinese sillago was reported in 2018, but the chromosome-level genome assembly has yet to be described.

description: In this paper, we introduce a deep learning aided constraint encoding method to tackle the frequency-constraint microgrid scheduling problem. The nonlinear function between system operating condition and frequency nadir is approximated by using a neural network, which admits an exact mixed-integer formulation (MIP). This formulation is then integrated with the scheduling problem to encode the frequency constraint. With the stronger representation power of the neural network, the resulting commands can ensure adequate frequency response in a realistic setting in addition to islanding success. The proposed method is validated on a modified 33-node system. Successful islanding with a secure response is simulated under the scheduled commands using a detailed three-phase model in Simulink. The advantages of our model are particularly remarkable when the inertia emulation functions from wind turbine generators are considered.

description: We use a chiral model for pion interactions, in the inverse amplitude formalism, to perform a simultaneous analysis of lattice QCD results for pion-pion scattering in all three isospin channels. The input is the finite-volume two-pion spectrum computed using lattice QCD from six ensembles on lattices elongated in one of the spatial dimensions. A two-flavor dynamical lattice QCD action is used with two quark masses corresponding to a pion mass of 315 MeV and 224 MeV. The spectrum in the elastic region is subjected to a global fit which takes into account full correlations across isospin, pion mass and decay constant. The parameters from the fit are used to perform a chiral extrapolation to the physical point. The cross-channel fit results in a more precise determination of the parameters of the model when compared with single channel fits. We obtain $m_πa_0^{I=0}=0.2132(9)$, and $m_πa_0^{I=2}=0.0433(2)$ as well as $m_σ=443(3)-i221(6)$ MeV and $m_ρ=724(4)-i67(1)$ MeV. Several aspects of scale setting and consistency with previous analyses of lattice QCD results are discussed as well.

description: The National Food Survey has been a carefully watched gauge for both wartime and postwar British food administration. It has measured the successes and the failures of the policies and programs for maintaining equitable distribution of foods essential to the civilian population of the United Kingdom during the prolonged and grim struggle, first against the enemy, then on the hard road back to some semblance of economic recovery. Because the Survey was conducted only for administrative use, its detailed findings were not published until late 1951. Although such findings were always available to key American food officials, the inner workings of the Survey have been little known on this side of the Atlantic. Accordingly, while in England for independent research at Cambridge University in 1955-56, Miss Burk prepared a report for administrative use in the Agricultural Marketing Service; this was done with the wholehearted cooperation of administrators and technical personnel who were responsible for the Survey and its interpretation. In this article we publish nonconfidential information from the report and some further research notes on these and other comparable data. Although Miss Burk is indebted to a number of civil servants of Her Majesty's Government for extended and frank discussions of problems involved in the Survey, her article represents essentially preliminary research findings. The article is not an official statement of either Her Majesty's Government or the U. S. Department of Agriculture.
