description: We describe the second version (v2.0.0) of the code ADG that automatically (1) generates all valid off-diagonal Bogoliubov many-body perturbation theory diagrams at play in particle-number projected Bogoliubov many-body perturbation theory (PNP-BMBPT) and (2) evaluates their algebraic expression to be implemented for numerical applications. This is achieved at any perturbative order $p$ for a Hamiltonian containing both two-body (four-legs) and three-body (six-legs) interactions (vertices). All valid off-diagonal BMBPT diagrams of order $p$ are systematically generated from the set of diagonal, i.e., unprojected, BMBPT diagrams. The production of the latter were described at length in https://doi.org/10.1016/j.cpc.2018.11.023 dealing with the first version of ADG. The automated evaluation of off-diagonal BMBPT diagrams relies both on the application of algebraic Feynman's rules and on the identification of a powerful diagrammatic rule providing the result of the remaining $p$-tuple time integral. The new diagrammatic rule generalizes the one already identified in https://doi.org/10.1016/j.cpc.2018.11.023 to evaluate diagonal BMBPT diagrams independently of their perturbative order and topology. The code ADG is written in Python3 and uses the graph manipulation package NetworkX. The code is kept flexible enough to be further expanded throughout the years to tackle the diagrammatics at play in various many-body formalisms that already exist or are yet to be formulated.

description: We have used our new technique for fully numerical evolutions of orbiting black-hole binaries without excision to model the last orbit and merger of an equal-mass black-hole system. We track the trajectories of the individual apparent horizons and find that the binary completed approximately one and a third orbits before forming a common horizon. Upon calculating the complete gravitational radiation waveform, horizon mass, and spin, we find that the binary radiated 3.2% of its mass and 24% of its angular momentum. The early part of the waveform, after a relatively short initial burst of spurious radiation, is oscillatory with increasing amplitude and frequency, as expected from orbital motion. The waveform then transitions to a typical `plunge' waveform; i.e. a rapid rise in amplitude followed by quasinormal ringing. The plunge part of the waveform is remarkably similar to the waveform from the previously studied `ISCO' configuration. We anticipate that the plunge waveform, when starting from quasicircular orbits, has a generic shape that is essentially independent of the initial separation of the binary.

description: It has been established that, in naturally occurring ice, exotic propagation modes exist for radio signals. An interesting consequence of this is that it seems possible for signals to propagate to the receiver from an area which lies in the expected shadow zone. We present a ray tracing script based on Fermat's principle that has been developed with the aim to model and understand these propagation modes. The results of this script have been found in agreement with an earlier prediction that over-densities are able to guide the ray paths. In addition to the in-ice problem of propagation modes we use this approach to evaluate approximations made in air-shower radio emission simulations and verify if the approximations break down for certain geometries.

We consider two different models for the electric charge distribution and demostrate that both imply stellar configurations with larger masses and that satisfy the equilibrium condition. The dynamical stability against radial oscillations is investigated. Our results demonstrate that the eigenfrequencies are modified by the presence of a net electric charge, but the instability, previously demonstrated for the electrically neutral case, is also present in charged charm stars.

Subjects: Demand and Price Analysis

description: The focus of this study is the estimation of the Australian demand for meat between 1967 and 1990, employing a demand systems approach which uses the linear approximate, almost ideal demand system (LA/AIDS) model. Two demand systems are estimated by maximum likelihood methods, one for aggregate types of meat and one for disaggregated meat products. After correcting for serial correlation in the two demand systems, restrictions from utility theory are imposed and tested for their appropriateness. By using a new data set on the Australian retail price and consumption offresh pork, ham and bacon, the results from the disaggregated model provide the first estimates of the own-price, cross-price and expenditure elasticities for these commodities.

description: Tourism has become the most dynamic and promising green industry in Dalishu Village. However, with the increase of the same type of tourist areas and the addition of other theme tourism destinations, the rural tourism of Dalishu Village is facing the problem of how to develop in homogenous competition and how to maintain stable development. This is also a problem that needs to be addressed seriously in the development of rural tourism. Starting from the image perception factors, this study chooses the interaction among image perception factors, satisfaction and loyalty as a perspective, in order to identify the important factors that play a key role in tourists' satisfaction and loyalty, and to provide a new driving force for the integrated development of rural tourism in Dalishu Village.

description: Bardsley and Harris (1987) test empirically the effects of changes In deterministic wealth and random income on the measure partial risk aversion. The paper, which is otherwise well written, failed to impose the relationship between the two effects and estimated them independently. Consequently, inconsistent estimates were derived for the elasticities of the measure of partial risk aversion with respect to wealth and to income. The purpose of this comment is to derive that relationship theoretically and to point out the resulting inconsistencies in the original paper.

description: The improved quark mass density- dependent model which includes the coupling between the quarks and a non-linear scalar field is presented. Numerical analysis of solutions of the model is performed over a wide range of parameters. The wave functions of ground state and the lowest one-particle excited states with even and odd parity are given. The root-mean squared radius, the magnetic moment and the ratio between the axial-vector and the vector beta-decay coupling constants of the nucleon are calculated. We found that the present model is successful to describe the properties of nucleon.

description: We introduce the concepts of a symmetry-protected sign problem and symmetry-protected magic to study the complexity of symmetry-protected topological (SPT) phases of matter. In particular, we say a state has a symmetry-protected sign problem or symmetry-protected magic, if finite-depth quantum circuits composed of symmetric gates are unable to transform the state into a non-negative real wave function or stabilizer state, respectively. We prove that states belonging to certain SPT phases have these properties, as a result of their anomalous symmetry action at a boundary. For example, we find that one-dimensional $\mathbb{Z}_2 \times \mathbb{Z}_2$ SPT states (e.g. cluster state) have a symmetry-protected sign problem, and two-dimensional $\mathbb{Z}_2$ SPT states (e.g. Levin-Gu state) have symmetry-protected magic. Furthermore, we comment on the relation between a symmetry-protected sign problem and the computational wire property of one-dimensional SPT states. In an appendix, we also introduce explicit decorated domain wall models of SPT phases, which may be of independent interest.

description: In this work, we consider decoherence of a central spin by a spin bath. In order to study the non-perturbative decoherence regimes, we develop an efficient mean-field-based method for modeling the spin-bath decoherence, based on the P-representation of the central spin density matrix. The method can be applied to longitudinal and transversal relaxation at different external fields. In particular, by modeling large-size quantum systems (up to 16000 bath spins), we make controlled predictions for the slow long-time decoherence of the central spin.

description: A set of sufficient conditions for the generalized covariant entropy bound given by Strominger and Thompson is as follows: Suppose that the entropy of matter can be described by an entropy current $s^a$. Let $k^a$ be any null vector along $L$ and $s\equiv -k^a s_a$. Then the generalized bound can be derived from the following conditions: (i) $s'\leq 2πT_{ab}k^ak^b$, where $s'=k^a\grad_a s$ and $T_{ab}$ is the stress energy tensor; (ii) on the initial 2-surface $B$, $s(0)\leq -{1/4}θ(0)$, where $θ$ is the expansion of $k^a$. We prove that condition (ii) alone can be used to divide a spacetime into two regions: The generalized entropy bound holds for all light sheets residing in the region where $s-{1/4}θ$. We check the validity of these conditions in FRW flat universe and a scalar field spacetime. Some apparent violations of the entropy bounds in the two spacetimes are discussed. These holographic bounds are important in the formulation of the holographic principle.

description: An analytical framework is developed for assessing the relative gains accruing to co-operators and non co-operators in a cartel arrangement involving production quotas. Key parameters determining the relative gains are identified. The values of these parameters in the context of Australian agriculture could result in greater gains for non co-operators than for co-operators. Suggestions are offered on some types of information that should be sought in feasibility studies before cartels are established.

description: In this paper the relationship between scientific agricultural research and aggregate rural productivity is investigated. The Solow 'residual' model is used to estimate productivity changes. An attempt is made to investigate the extent to which scientific research, measured by scientific personnel, 'explains' technical change. An education and climatic variable are added to the model. The results suggest a positive relationship between scientific research, climate and aggregate productivity.

Diet and the microbiome

Publisher: name: University of Limerick

subject: Biological sciences

description: Over the last few decades, consumption of the Western diet has coincided with an increase in the prevalence of chronic metabolic and inflammatory diseases such as Colorectal cancer (CRC), Hidradenitis suppurativa (HS) and Type II diabetes mellitus (T2DM). Patients harbouring these diseases have an altered microbiota composition when compared to controls. Meanwhile, specific taxa have been identified as directly contributing to their pathogenesis. Specific dietary components have been identified as beneficial or detrimental to host health through microbiota dependent and independent mechanisms. Dietary manipulation of the microbiota has shown promising potential in disease prevention and treatment. Furthermore, evidence suggests that the microbiota has potential to be used as a biomarker for diagnosis, prognosis or risk profiling of different diseases. However, to precisely and effectively use diet and/or microbiota-based therapies in a clinical setting more must be learned about how each factor influences each other and the host. With respect to these research questions, this thesis aims to better understand diet and the microbiome in the setting of metabolic and inflammatory disease. We show that the majority of patients who underwent surgical resection for CRC had a microbiota composition that was most similar to patients newly diagnosed with CRC while, in one third of patients the microbiota reverted toward normal. Interestingly, the consumption of the fibre-rich and chemoprotective cruciferous vegetables co-varied with differences in microbiota composition. We also describe how 40% of patients with HS have a microbiota composition similar to patients with Crohn’s disease (CD) while the remaining 60% have a microbiota composition most similar to controls. Interestingly, patients with a CD-like microbiota configuration consumed significantly more carbonated soft drinks than those with a normal microbiota composition. Finally, we show that dietary fibre (yeast β-glucan) exerted a hypoglycaemic effect in patients with T2DM when compared to the placebo control. Significant differences in fasting gluose and insulin coincided with enrichment of fecal bile acids in patients administered yeast β-glucan including tauroursodexoycholic acid which is known improve glucose control and lower insulin resistance. Overall, these findings highlight diet-microbiome associations and risk development of disease. We also demonstrate the use of diet as an effective therapy to alleviate metabolic and inflammatory disease.

Biochemical characterization of signaling pathways regulating cell survival
Creators: name: Schubert, Kathryn M
Publisher: name: University of British Columbia
Year: 2009

description: The granulocyte/macrophage colony stimulating factor (GM-CSF) exerts its antiapoptotic effects on hemopoietic cells by activating multiple cellular signaling pathways including the phosphatidylinositol 3'-OH kinase (PI3K) cell survival pathway and the Ras-Raf-MEK-ERK kinase cascade. I hypothesized that cytokines activate each of these pathways to regulate components of the apoptotic machinery, including members of the Bcl-2 family. The mechanism by which cytokines such as GM-CSF regulate expression of Bcl-2 family members was examined in several models, including primary human eosinophils and basophils, and the hemopoietic cell lines TF-1 and MC/9. Protein expression of one pro-survival Bcl-2 family member, Mcl-1, was found to be dependent upon phosphatidylinositol (PI) 3-kinase. The cytokine-induced increase in Mcl-1 mRNA transcription was not dependent upon PI3K, thus dissociating the immediate-early transcription factors responsible for Mcl-1 transcription from the PI3K signaling pathway. In contrast, Mcl-1 mRNA levels were dependent upon MEK activation, suggesting a role for the Ras-MEK-ERK pathway in Mcl-1 transcription. However, activation of PI3K was shown to be necessary for GM-CSF to stimulate Mcl-1 protein translation. This was not due to any effect on prolonging the half-life of the protein. I was also interested in other pathways that may regulate PI3K and Mcl-1 to affect cell survival. The second messenger ceramide has been implicated in a host of cellular processes including growth arrest and apoptosis. The relationship between ceramide signaling and the activation of PI3K and its downstream target, protein kinase B (PKB) was examined in detail. PKB activation was observed following stimulation of cells with GM-CSF. Addition of cell-permeable analogs, C₂- or C₆-ceramide, caused a partial loss (50-60%) of PKB activation and resulted in reduced Mcl-1 translation. These reductions were not a result of a decrease in PI(3,4,5)P₃ or PI(3,4)P₂ generation by PI3K. Two residues of PKB (threonine 308 and serine 473) require phosphorylation for maximal PKB activation. Ser⁴⁷³ phosphorylation was consistently reduced by treatment with ceramide, whereas Thr³⁰⁸ phosphorylation remained unaffected. In further experiments, ceramide appeared to accelerate Ser⁴⁷³ dephosphorylation, suggesting the activation of a phosphatase. Consistent with this, the reduction in Ser⁴⁷³ phosphorylation was inhibited by the phosphatase inhibitors okadaic acid and calyculin A. Surprisingly, Thr³⁰⁸ phosphorylation was abolished in cells treated with these inhibitors, revealing a novel mechanism of regulation of Thr³⁰⁸ phosphorylation. These results demonstrate that PDK2-catalyzed phosphorylation of Ser⁴⁷³ is the principal target of a ceramide-activated phosphatase, which may regulate cell survival by reducing the level of pro-survival proteins such as Mcl-1.

description: Secure delegated quantum computing allows a computationally weak client to outsource an arbitrary quantum computation to an untrusted quantum server in a privacy-preserving manner. One of the promising candidates to achieve classical delegation of quantum computation is classical-client remote state preparation ($RSP_{CC}$), where a client remotely prepares a quantum state using a classical channel. However, the privacy loss incurred by employing $RSP_{CC}$ as a sub-module is unclear. In this work, we investigate this question using the Constructive Cryptography framework by Maurer and Renner (ICS'11). We first identify the goal of $RSP_{CC}$ as the construction of ideal RSP resources from classical channels and then reveal the security limitations of using $RSP_{CC}$. First, we uncover a fundamental relationship between constructing ideal RSP resources (from classical channels) and the task of cloning quantum states. Any classically constructed ideal RSP resource must leak to the server the full classical description (possibly in an encoded form) of the generated quantum state, even if we target computational security only. As a consequence, we find that the realization of common RSP resources, without weakening their guarantees drastically, is impossible due to the no-cloning theorem. Second, the above result does not rule out that a specific $RSP_{CC}$ protocol can replace the quantum channel at least in some contexts, such as the Universal Blind Quantum Computing (UBQC) protocol of Broadbent et al. (FOCS '09). However, we show that the resulting UBQC protocol cannot maintain its proven composable security as soon as $RSP_{CC}$ is used as a subroutine. Third, we show that replacing the quantum channel of the above UBQC protocol by the $RSP_{CC}$ protocol QFactory of Cojocaru et al. (Asiacrypt '19), preserves the weaker, game-based, security of UBQC.

description: Rural complex is a bright spot for China to realize the development of new industries for rural revitalization. Starting from the concept, development history and current situation of rural complex, based on the perspective of production-living-ecological space, according to the different characteristics of agriculture and tourism, 3 secondary indices and 18 tertiary indices were selected, and each of them was weighted using the Delphi expert consultation method and analytic hierarchy process (AHP) to construct an evaluation system for the coupling degree of agriculture and tourism in rural complex. The results show gross domestic product and forest coverage have the most significant impact on agriculture, economic benefits and the ecological water quality of tourist attractions have the most significant impact on the tourism industry, and tourism economic benefits and agricultural ecological benefits have the most significant impact on rural complex.

description: The production function approach has been one of the two main ex-post procedures used to estimate the rate of return to agricultural research. A critical part of estimating the marginal internal rate of return (MIRR) is the procedure adopted to spread the benefits of research through time. Past studies using this approach have given only brief consideration to this computational procedure. The objective in this study was to review the different computational procedures used and, then, using cross-section production function estimates for U.S. agriculture, determine whether the MIRR estimates are sensitive to the computational procedure used. The results from this comparison indicate a large range in the estimates. The implication, then, is that careful consideration should be given to the choice of computational procedure, both when undertaking such a study and when comparing the results of different studies.

description: We have investigated the fractal characteristics and shape complexity of the fracture surfaces of swelled isotactic polypropylene Y1600 in supercritical carbon dioxide fluid through the consideration of the statistics of the islands in binary SEM images. The distributions of area $A$, perimeter $L$, and shape complexity $C$ follow power laws $p(A)\sim A^{-(μ_A+1)}$, $p(L)\sim L^{-(μ_L+1)}$, and $p(C)\sim C^{-(ν+1)}$, with the scaling ranges spanning over two decades. The perimeter and shape complexity scale respectively as $L\sim A^{D/2}$ and $C\sim A^q$ in two scaling regions delimited by $A\approx 10^3$. The fractal dimension and shape complexity increase when the temperature decreases. In addition, the relationships among different power-law scaling exponents $μ_A$, $μ_B$, $ν$, $D$, and $q$ have been derived analytically, assuming that $A$, $L$, and $C$ follow power-law distributions.

description: Here we extend the conservation of energy in the framework of the thin layer approximation to the asymmetrical case. Four types of interstellar medium are analysed, in which the density follows an inverse square profile, a power law profile, an exponential profile and a toroidal profile. An analytical solution for the radius as a function of time and the polar angle in spherical coordinates is derived in the case of the inverse square profile. The analytical and numerical results are applied to two supernova remnants: SN 1987A and SN 1006. The back reaction due to the radiative losses is evaluated in the case of the inverse square profile for the surrounding medium. Two models for the image formation are presented, which explain the triple ring visible in SN 1987A and the jet feature of SN 1006.

description: Brain tumor segmentation intends to delineate tumor tissues from healthy brain tissues. The tumor tissues include necrosis, peritumoral edema, and active tumor. In contrast, healthy brain tissues include white matter, gray matter, and cerebrospinal fluid. The MRI based brain tumor segmentation research is gaining popularity as; 1. It does not irradiate ionized radiation like X-ray or computed tomography imaging. 2. It produces detailed pictures of internal body structures. The MRI scans are input to deep learning-based approaches which are useful for automatic brain tumor segmentation. The features from segments are fed to the classifier which predict the overall survival of the patient. The motive of this paper is to give an extensive overview of state-of-the-art jointly covering brain tumor segmentation and overall survival prediction.

description: Spatially disaggregated maps of the incidence of poverty can be constructed by combining household survey data and census data. In some cases, however, statistical authorities are reluctant, for reasons of confidentiality, to release household-level census data. This paper examines the loss in precision associated with using aggregated census data, such as village- or district-level means of the data. We show analytically that using aggregated census data will result in poverty rates that are biased downward (upward) if the rate is below (above) 50 percent and that the bias approaches zero as the poverty rate approaches zero, 50 percent, and 100 percent. Using data from Vietnam, we find that the average absolute error in estimating provincial poverty rates is about 2 percentage points if the data are aggregated to the enumeration-area level and around 3-4 percentage points if they are aggregated to the provincial level. Even census data aggregated to the provincial level perform reasonably well in ranking the 61 provinces by the incidence of poverty: the average absolute error in ranking is 0.92.

description: China has a vast territory and numerous ethnic groups, forming various regional cultures with different styles. However, the architectural design education in colleges and universities of China used to learn from the West, and there is homogeneity in teaching mode, teaching content, and curriculum system construction, lacking regional cultural characteristics. In the context of regional culture, combined with the cultivation of students’ innovation ability, the teaching of the course of Architectural Landscape Design is discussed in this article, in order to promote the inheritance and development of regional culture in landscape design teaching and promote students to truly understand the artistry and practicality of regional cultural resources.

description: This paper is an ELITR system submission for the non-native speech translation task at IWSLT 2020. We describe systems for offline ASR, real-time ASR, and our cascaded approach to offline SLT and real-time SLT. We select our primary candidates from a pool of pre-existing systems, develop a new end-toend general ASR system, and a hybrid ASR trained on non-native speech. The provided small validation set prevents us from carrying out a complex validation, but we submit all the unselected candidates for contrastive evaluation on the test set.

description: We consider a nonlinear elliptic equation driven by a nonhomogeneous differential operator plus an indefinite potential. On the reaction term we impose conditions only near zero. Using variational methods, together with truncation and perturbation techniques and critical groups, we produce three nontrivial solutions with sign information. In the semilinear case we improve this result by obtaining a second nodal solution for a total of four nontrivial solutions. Finally, under a symmetry condition on the reaction term, we generate a whole sequence of distinct nodal solutions.

description: This study uses data from 1996/97 through 1998/99 to examine the relative efficiency of production of crops in Bangladesh and their comparative advantage in international trade as measured by net economic profitability (the profitability using economic, rather than financial costs and prices), and the domestic resource cost ratio, (the amount of value of non-tradable domestic resources used in production divided by the value of tradable products). The economic profitability analysis demonstrates that Bangladesh has a comparative advantage in domestic production of rice for import substitution. However, at the export parity price, economic profitability of rice is generally less than economic profitability of many non-rice crops, implying that Bangladesh has more profitable options other than production for rice export. Several non-cereal crops, including vegetables, potatoes and onions have financial and economic returns that are as high as or higher than those of High Yielding Variety (HYV) rice. The relatively minor role in cropping systems of these crops despite their higher returns, can largely be attributed to high price risks associated with marketing, suggesting the need for further development of agro-processing industries, rural infrastructure, and marketing networks.
Shear-thickening and entropy-driven reentrance

description: We discuss a generic mechanism for shear-thickening analogous to entropy-driven phase reentrance. We implement it in the context of non-relaxational mean-field glassy systems: although very simple, the microscopic models we study present a dynamical phase diagram with second and first order stirring-induced jamming transitions leading to intermittency, metastability and phase coexistence as seen in some experiments. The jammed state is fragile with respect to change in the stirring direction. Our approach provides a direct derivation of a Mode-Coupling theory of shear-thickening.

description: This paper examines the mechanisms that transmit isolation into poverty in Madagascar using household survey data combined with a census of administrative communes. Given the importance of agriculture to the rural poor, where nine out of ten poor persons is engaged in farming, we concentrate on isolation manifesting itself in the form of high transaction costs such as the cost of transporting agricultural commodities to major market centers. We find that (a) the incidence of poverty in rural Madagascar increases with remoteness; (b) yields of major staple crops fall considerably as one gets farther away from major markets; (c) and the use of agricultural inputs declines with isolation. Simulation results using output from rice production function estimates suggest that halving travel time per kilometer on major highways (feeder roads) will increase primary season rice production by 1.3 (1.0) percent.
Magnetic helicity in primordial and dynamo scenarios of galaxies

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Some common properties of helical magnetic fields in decaying and driven turbulence are discussed. These include mainly the inverse cascade that produces fields on progressively larger scales. Magnetic helicity also restricts the evolution of the large scale field: the field decays less rapidly than a non-helical field, but it also saturates more slowly, i.e. on a resistive time scale if there are no magnetic helicity fluxes. The former effect is utilized in primordial field scenarios, while the latter is important for successfully explaining astrophysical dynamos that saturate faster than resistively. Dynamo action is argued to be important not only in the galactic dynamo, but also in accretion discs in active galactic nuclei and around protostars, both of which contribute to producing a strong enough seed magnetic field. Although primordial magnetic fields may be too weak to compete with these astrophysical mechanisms, such fields could perhaps still be important in producing polarization effects in the cosmic background radiation.
