description: Acute cholangitis (AC) is a condition of bacterial infection in the biliary tract with a high mortality rate of around 10%. Direct association between presence of bacteremia and 30-day mortality among AC patients is sparsely investigated and remains unclear. Our aim was to investigate association between bacteremia and 30-day mortality among patients with AC included over a period of 25 years. All AC patients that underwent endoscopic retrograde cholangiopancreatography (ERCP) at Odense University Hospital, between 1 January 1990 and 31 October 2015, were identified using a prospective ERCP database. Blood culture results from the patients along with antimicrobial resistance patterns were collected from a bacteremia research database. During the study period, 775 consecutive AC patients underwent ERCP and blood cultures were collected from 528 patients. Among these patients 48% (n = 260) had bacteremia. Overall, 30-day mortality in patients with blood cultures performed was 13% (n = 69). In patients with bacteremia, 30-day mortality was 19% (n = 49), compared to 7% (n = 20) in patients without bacteremia (p p p = .02). Our results indicate that presence of bacteremia was associated with a nearly fourfold increase in 30-day mortality among AC patients.

description: The land consolidation projects in Anhui Province have brought huge economic and social benefits and made active contribution to increasing integrated grain productivity, stabilizing farmland area, increasing farmers’ income, accelerating new socialist countryside construction, and promoting integrated urban and rural development. With more than ten years of exploration and attempt, land consolidation, reclamation and development of Anhui Province has established relatively complete policy, technical and business type regulations. However, there are still some weak links and problems, leading to slow project progress, and quality up to standard, fund management not standardized, and the masses not satisfactory for few projects. It summarized experience and achievements of rural land consolidation in Anhui Province and elaborated major existing problems in management of project implementation. Finally, it came up with pertinent recommendations for project implementation in rural land consolidation.

description: Correlation for $p_T$ cross section between 2.0 < |y| < 2.4 and 2.8 < |y| < 3.6
description: CERN-LHC. This paper presents for the first time a precise measurement of the production properties of the $Z$ boson in the full phase space of the decay leptons. This is in contrast to the many previous precise unfolded measurements performed in the fiducial phase space of the decay leptons. The measurement is obtained from proton--proton collision data collected by the ATLAS experiment in 2012 at $\sqrt{s} = 8$ TeV at the LHC and corresponding to an integrated luminosity of 20.2 fb$^{-1}$. The results, based on a total of 15.3 million $Z$-boson decays to electron and muon pairs, extend and improve a previous measurement of the full set of angular coefficients describing $Z$-boson decay. The double-differential cross-section distributions in $Z$-boson transverse momentum $p_T$ and rapidity $y$ are measured in the pole region, defined as $80 < m_{\ell\ell} < 100$ GeV, over the range $|y| < 3.6$. The total uncertainty of the normalised cross-section measurements in the peak region of the $p_T$ distribution is dominated by statistical uncertainties over the full range and increases as a function of rapidity from $0.5-1.0$% for $|y| < 2.0$ to $2-7$% at higher rapidities. The results for the rapidity-dependent transverse momentum distributions are compared to state-of-the-art QCD predictions, which combine in the best cases approximate N$^4$LL resummation with N$^3$LO fixed-order perturbative calculations. The differential rapidity distributions integrated over $p_T$ are even more precise, with accuracies from $0.2-0.3$% for $|y| < 2.0$ to $0.4-0.9$% at higher rapidities, and are compared to fixed-order QCD predictions using the most recent parton distribution functions. The agreement between data and predictions is quite good in most cases.

description: We study singularity formation in spherically symmetric solutions of the charge-one and charge-two sector of the (2+1)-dimensional S^2 sigma-model and the (4+1)-dimensional Yang-Mills model, near the adiabatic limit. These equations are non-integrable, and so studies are performed numerically on rotationally symmetric solutions using an iterative finite differencing scheme that is numerically stable. We evaluate the accuracy of predictions made with the geodesic approximation. We find that the geodesic approximation is extremely accurate for the charge-two sigma-model and the Yang-Mills model, both of which exhibit fast blowup. The charge-one sigma-model exhibits slow blowup. There the geodesic approximation must be modified by applying an infrared cutoff that depends on initial conditions.

description: In this work we study and provide a full description, up to a finite index subgroup, of the dynamics of solvable complex Kleinian subgroups of PSL(3,C). These groups havesimpledynamics, contrary to strongly irre-ducible groups. Because of this, we propose to define elementary subgroups of PSL(3,C) as solvable groups. We show that triangular groups can be de-composed in four layers, via the semi-direct product of fourtypes of elements,with parabolic elements in the inner most layers and loxodromic elements inthe outer layers. It is also shown that solvable groups, up toa finite index sub-group, act properly and discontinuously on the complement of either a line,two lines, a line and a point outside of the line, or a pencil oflines passingthrough a point. These results are another step towards the completion of thestudy of elementary subgroups of PSL(3,C)

description: We suggest that breaking of SU(3) flavor symmetry mainly resides in the baryon wave--functions while the charge operators have no (or only small) explicit symmetry breaking components. We utilize the collective coordinate approach to chiral soliton models to support this picture. In particular we compute the $g_A/g_V$ ratios for hyperon beta--decay and the strangeness contribution to the nucleon axial current matrix elements and analyze their variation with increasing flavor symmetry breaking.

description: Code-switching (CS) is a widespread phenomenon among bilingual and multilingual societies. The lack of CS resources hinders the performance of many NLP tasks. In this work, we explore the potential use of bilingual word embeddings for code-switching (CS) language modeling (LM) in the low resource Egyptian Arabic-English language. We evaluate different state-of-the-art bilingual word embeddings approaches that require cross-lingual resources at different levels and propose an innovative but simple approach that jointly learns bilingual word representations without the use of any parallel data, relying only on monolingual and a small amount of CS data. While all representations improve CS LM, ours performs the best and improves perplexity 33.5% relative over the baseline.

description: An equation for the quasi-static soliton ansatz depending on an arbitrary set of collective variables is covariantly derived on the basis of the variational approach to the method of collective variables. The field configuration and the static stresses of the deformed $Φ^4$-kink that are produced by the excitation of the internal soliton mode are exactly determined. The kink interaction potential at large distances is considered for the example of the nonlinear Klein-Gordon system. A general approach to the problem of exactly determining the intersoliton potential for the entire set of physically admissible two-soliton configurations is discussed.

description: During the last decade, a significant increase in the use of biologic medicine has occurred, accounting for the greatest healthcare expenditure, among inflammatory bowel disease (IBD) patients. The objective of this study was to analyse the prevalence of and time to first intestinal resection surgery in a Danish nationwide cohort of Crohn’s disease (CD) and ulcerative colitis (UC) patients, stratified on biologic treatment status. This retrospective population-based study included IBD patients diagnosed between 2003 and 2015 identified in the Danish National Patient Registry (NPR). The frequency of first-time surgery with intestinal resection and time to surgery was analysed among CD and UC patients between 2003 and 2016. A total of 2328 CD and 2128 UC patients underwent surgery between 2003 and 2016 (23% and 10% of all incident CD and UC patients, respectively). Up until 2008, the frequency of surgery gradually declined for both patient groups and an increase in the frequency of patients receiving biological treatment was observed. Subsequently, the frequency of surgery for both CD and UC patients remained stable despite a steady increase in biologic treatment use. The registered increase in the fraction of patients on biologic treatment (mostly TNF-α inhibitors) did not result in changes in the rates of major surgeries with intestinal resection in CD and UC patients.

description: As currently implemented, single-photon sources cannot be made to produce single photons with high probability, while simultaneously suppressing the probability of yielding two or more photons. Because of this, single photon sources cannot really produce single photons on demand. We describe a multiplexed system that allows the probabilities of producing one and more photons to be adjusted independently, enabling a much better approximation of a source of single photons on demand. The scheme uses a heralded photon source based on parametric downconversion, but by effectively breaking the trigger detector area into multiple regions, we are able to extract more information about a heralded photon than is possible with a conventional arrangement. This scheme allows photons to be produced along with a quantitative ``certification'' that they are single photons. Some of the single-photon certifications can be significantly better than what is possible with conventional downconversion sources (using a unified trigger detector region), as well as being better than faint laser sources. With such a source of more tightly certified single photons, it should be possible to improve the maximum secure bit rate possible over a quantum cryptographic link. We present an analysis of the relative merits of this method over the conventional arrangement.

description: We perform numerical simulations of magneto-rotational instability in a local patch of accretion disk in which radiation pressure exceeds gas pressure. Such conditions may occur in the central regions of disks surrounding compact objects in active galactic nuclei and Galactic X-ray sources. We assume axisymmetry, and neglect vertical stratification. The growth rates of the instability on initially uniform magnetic fields are consistent with the linear analysis of Blaes & Socrates 2001. As is the case when radiation effects are neglected, the non-linear development of the instability leads to transitory turbulence when the initial magnetic field has no net vertical flux. During the turbulent phase, angular momentum is transported outwards. The Maxwell stress is a few times the Reynolds stress, and their sum is about four times the mean pressure in the vertical component of the magnetic field. For magnetic pressure exceeding gas pressure, turbulent fluctuations in the field produce density contrasts about equal to the ratio of magnetic to gas pressure. These are many times larger than in the corresponding gas pressure dominated situation, and may have profound implications for the steady-state vertical structure of radiation-dominated disks. Diffusion of radiation from compressed regions damps turbulent motions, converting kinetic energy into photon energy.

description: The quantum fluctuation of the relative location of two (n-1)-dimensional de Sitter branes (i.e., of n spacetime dimensions) embedded in the (n+1)-dimensional anti-de Sitter bulk, which we shall call the quantum radion, is investigated at the linear perturbation level. The quantization of the radion is done by deriving the effective action of the radion. Assuming the positive tension brane is our universe, the effect of the quantum radion is evaluated by using the effective Einstein equations on the brane in which the radion contributes to the effective energy momentum tensor at the linear order of the radion amplitude. Specifically, the rms effective energy density arising from the quantum radion is compared with the background energy density. It is found out that this ratio remains small for reasonable values of the parameters of the model even without introducing a stabilizing mechanism for radion, although the radion itself has a negative mass squared and is unstable. The reason behind this phenomenon is also discussed.

description: Spermatozoa self-propel by propagating bending waves along a predominantly active elastic flagellum. The organized structure of the "9 + 2" axoneme is lost in the most-distal few microns of the flagellum, and therefore this region is unlikely to have the ability to generate active bending; as such it has been largely neglected in biophysical studies. Through elastohydrodynamic modeling of human-like sperm we show that an inactive distal region confers significant advantages, both in propulsive thrust and swimming efficiency, when compared with a fully active flagellum of the same total length. The beneficial effect of the inactive end piece on these statistics can be as small as a few percent but can be above 430%. The optimal inactive length, between 2-18% of the total length, depends on both wavenumber and viscous-elastic ratio, and therefore is likely to vary in different species. Potential implications in evolutionary biology and clinical assessment are discussed.

description: Correlation for $p_T$ cross section between 2.4 < |y| < 2.8 and 1.2 < |y| < 1.6
description: CERN-LHC. This paper presents for the first time a precise measurement of the production properties of the $Z$ boson in the full phase space of the decay leptons. This is in contrast to the many previous precise unfolded measurements performed in the fiducial phase space of the decay leptons. The measurement is obtained from proton--proton collision data collected by the ATLAS experiment in 2012 at $\sqrt{s} = 8$ TeV at the LHC and corresponding to an integrated luminosity of 20.2 fb$^{-1}$. The results, based on a total of 15.3 million $Z$-boson decays to electron and muon pairs, extend and improve a previous measurement of the full set of angular coefficients describing $Z$-boson decay. The double-differential cross-section distributions in $Z$-boson transverse momentum $p_T$ and rapidity $y$ are measured in the pole region, defined as $80 < m_{\ell\ell} < 100$ GeV, over the range $|y| < 3.6$. The total uncertainty of the normalised cross-section measurements in the peak region of the $p_T$ distribution is dominated by statistical uncertainties over the full range and increases as a function of rapidity from $0.5-1.0$% for $|y| < 2.0$ to $2-7$% at higher rapidities. The results for the rapidity-dependent transverse momentum distributions are compared to state-of-the-art QCD predictions, which combine in the best cases approximate N$^4$LL resummation with N$^3$LO fixed-order perturbative calculations. The differential rapidity distributions integrated over $p_T$ are even more precise, with accuracies from $0.2-0.3$% for $|y| < 2.0$ to $0.4-0.9$% at higher rapidities, and are compared to fixed-order QCD predictions using the most recent parton distribution functions. The agreement between data and predictions is quite good in most cases.

description: In many parts of Africa, traditional household structures consisting of an extended family headed by a patriarch are giving way to other types of households -- e.g. nuclear families, female-headed households -- as a result of migration, urbanisation and population pressures on land. In this paper, we explore whether traditional norms which determine how resources are allocated within the household are affected by the evolution of household structures. We show that the allocation of resources, for production and consumption, are closer to being efficient in nuclear family households as compared to extended family households. The findings are consistent with the hypothesis that individuals belonging to the same nuclear family have stronger ties, enabling them to commit to more efficient contracts infeasible for those connected through an extended family relation.
Generating multipartite spin states with fermionic atoms in a driven optical lattice

description: We propose a protocol for generating generalized GHZ states using ultracold fermions in 3D optical lattices or optical tweezer arrays. The protocol uses the interplay between laser driving, onsite interactions and external trapping confinement to enforce energetic spin- and position-dependent constraints on the atomic motion. These constraints allow us to transform a local superposition into a GHZ state through a stepwise protocol that flips one site at a time. The protocol requires no site-resolved drives or spin-dependent potentials, exhibits robustness to slow global laser phase drift, and naturally makes use of the harmonic trap that would normally cause difficulties for entanglement-generating protocols in optical lattices. We also discuss an improved protocol that can compensate for holes in the loadout at the cost of increased generation time. The state can immediately be used for quantum-enhanced metrology in 3D optical lattice clocks, opening a window to push the sensitivity of state-of-the-art sensors beyond the standard quantum limit.

description: Nonfarm activities (NFA) are a crucial component of the livelihood strategies of China’s rural households. Empirical evidence shows that 51% of rural households’ income in Asia is from nonfarm earnings (Haggblade, Hazell and Reardon 2007). However, the increasingly uneven spatial distribution of these nonfarm economies has raised the concerns in many countries. It is found that rural towns or intermediate cities play the more important roles in rural poverty reduction than big cities (Berdegué et al. 2015), yet, we still see more migrants concentrating in urban big cities in China. To explore this paradoxical situation will provide some evidences for other developing countries experiencing rapid yet unbalanced urbanization. In this paper, we used a unique data set to find out what are the factors driving rural migrant’s destination choice and whether they are always attracted by large cities. Apart from this main research question, several other contributions are made to the literature. First, this paper performs pioneer research by conducting the estimation of the determinants of Chinese rural off-farm worker’s locational choice, including and comparing both local and migratory NFA, both of which are important among rural households in China, yet the former is generally ignored in the literature. Second, the Nested-Logit Model is used to relax the irrelevant alternatives assumption, proved to be inappropriate if directly adopted traditional Logit or Multinomial Logit model in our case. The results suggested the importance of transportation as well as education to attract rural migrants. We did not see rural migrants preferring larger cities while facing with decreasing travel distances. For rural nonfarm economy, it is also important to improve agricultural performance in rural areas to generate multiplier effects as well as providing education/trainings to rural off-farm workers to be involved in higher-skilled NFA.

description: A reggeized model for ηand η' photoproduction on the nucleon is presented. In this model, t-channel vector meson exchanges are described in terms of Regge trajectories to comply with the correct high energy behavior. We compare this reggeized model with an isobar model (η-MAID), where the t-channel exchanges are described by ρand ωpoles. Both models contain the same resonance contributions, and describe current γp \to ηp data up to E_γ^{lab} = 2 GeV quite well, but only the reggeized model can be successfully extended to higher energies. For the γp \to η' p reaction, the reggeized model is found to be able to give a satisfactory description. For the differential cross section data from SAPHIR, we find that the observed linear forward rise in cos(theta) near E_γ^{lab} = 1.6 GeV can be well described by the interference of an S11 resonance and the Regge trajectory exchanges without any need for an additional P-wave resonance.
