description: Elevated concentrations of palmitate in serum of obese individuals can impair endothelial function, contributing to development of cardiovascular disease. Although several molecular mechanisms of palmitate-induced endothelial dysfunction have been proposed, there is no consensus on what signaling event is the initial trigger of detrimental palmitate effects. Here we report that inhibitors of ER stress or ceramid synthesis can rescue palmitate-induced autophagy impairment in macro- and microvascular endothelial cells. Furthermore, palmitate-induced cholesterol synthesis was reverted using these inhibitors. Similar to cell culture data, autophagy markers were increased in serum of obese individuals. Subsequent lipidomic analysis revealed that palmitate changed the composition of membrane phospholipids in endothelial cells and that these effects were not reverted upon application of above-mentioned inhibitors. However, ER stress inhibition in palmitate-treated cells enhanced the synthesis of trilglycerides and restored ceramide levels to control condition. Our results suggest that palmitate induces ER-stress presumably by shift in membrane architecture, leading to impaired synthesis of triglycerides and enhanced production of ceramides and cholesterol, which altogether enhances lipotoxicity of palmitate in endothelial cells.

description: This position paper discusses emerging behavioral, social, and economic dynamics related to the COVID-19 pandemic and puts particular emphasis on two emerging issues: First, delayed effects (or second strikes) of pandemics caused by dread risk effects are discussed whereby two factors which might influence the existence of such effects are identified, namely the accessibility of (mis-)information and the effects of policy decisions on adaptive behavior. Second, the issue of individual preparedness to hazardous events is discussed. As events such as the COVID-19 pandemic unfolds complex behavioral patterns which are hard to predict, sophisticated models which account for behavioral, social, and economic dynamics are required to assess the effectivity and efficiency of decision-making.

The role of inflammation and amyloid beta in Alzheimer disease pathology

description: Alzheimer disease (AD) is the most common form of dementia. Due to longer life-spans the number of affected individuals is expected to triple over the next few decades. As a consequence, a great deal of research is focused on determining the many processes by which the disease manifests as well as in discovering biomarkers and therapeutics to aid in diagnosis and disease prevention. The neuropathological hallmarks of AD include extracellular deposits of amyloid into senile plaques, accumulation of abnormal Tau filaments into neurofibrillary tangles, extensive neurodegeneration and inflammation. Although significant advances have been made in AD neurodegeneration, there still remain many unanswered and unforeseen aspects to the disease. It has been established that microglia, the immune cells of the brain, become activated in response to amyloid; however, the precise intracellular responses of microglia to amyloid and the relationship between microglia and amyloid deposition or clearance is unresolved. There have been many genes identified whose expression is upregulated in activated microglia and many of them have been proposed to be used as markers for inflammation. It has been demonstrated in humans that serum levels of melanotransferrin (p97), an iron binding molecule, is elevated in individuals affected with AD and that it is the activated, plaque-associated microglia that are responsible for this upregulation. This thesis further investigated the association between microglial activation and p97 gene expression and found that the levels of p97, both mRNA and protein, are increased in activated microglia in culture. The change in gene expression occurred largely in response to amyloid treatment possibly by the regulation of the AP-1 transcription factor downstream of the p38 mitogen-activated protein kinase pathway.

Eyes on the data : how the methodology of the 2030 Agenda contributes to its probable failure

description: More than halfway through the 15-year timeline, the world is still far from reaching the 17 Sustainable Development Goals (SDGs). This study locates one important reason for this in the specific design of the 2030 Agenda's methodology, the indicator-based goal-setting. In this, the Global Indicator Framework (GIF) should play a central role as a basis for political decisions and as an instrument for critical political communication. However, drawing on social science indicator research, this article shows that shortcomings in the GIF's genesis have led to the 2030 Agenda's effectiveness being severely limited. These limitations are: the one-sided focus on the provision of data, which results in the neglect of questions of implementation and tensions between and within political and statistical actors, which in turn leads to an undermining of the GIF itself. As a result, the GIF shows several crucial gaps in terms of content, is characterised by discrepancies between the political target and the measurement content of the indicators, and features indicators that change the goals through their measurement content. In response, the article notes a tendency towards non-use of the indicators, which undermines the whole 2030 Agenda. The results of this study can thus also be used as a basis for the future implementation of indicator-based policies.
Do All Elliptic Curves of the Same Order Have the Same Difficulty of Discrete Log?

description: The aim of this paper is to justify the common cryptographic practice of selecting elliptic curves using their order as the primary criterion. We can formalize this issue by asking whether the discrete log problem (DLOG) has the same difficulty for all curves over a given finite field with the same order. We prove that this is essentially true by showing polynomial time random reducibility of DLOG among such curves, assuming the Generalized Riemann Hypothesis (GRH). We do so by constructing certain expander graphs, similar to Ramanujan graphs, with elliptic curves as nodes and low degree isogenies as edges. The result is obtained from the rapid mixing of random walks on this graph. Our proof works only for curves with (nearly) the same endomorphism rings. Without this technical restriction such a DLOG equivalence might be false; however, in practice the restriction may be moot, because all known polynomial time techniques for constructing equal order curves produce only curves with nearly equal endomorphism rings.

description: The Heisenberg-Ising spin ladder is one of the few short-range models showing confinement of elementary excitations without the need of an external field, neither transverse nor longitudinal. This feature makes the model suitable for an experimental realization with ultracold atoms. In this paper, we combine analytic and numerical techniques to precisely characterize its spectrum in the regime of Hamiltonian parameters showing confinement. We find two kinds of particles, which we dub intrachain and interchain mesons, that correspond to bound states of kinks within the same chain or between different ones, respectively. The ultimate physical reasons leading to the existence of two families of mesons is a residual double degeneracy of the ground state: the two types of mesons interpolate either between the same vacuum (intrachain) or between the two different ones (interchain). While the intrachain mesons can also be qualitatively assessed through an effective mean field description and were previously known, the interchain ones are new and they represent general features of spin ladders with confinement.

description: In this article, we examine the economy-wide effects of three alternative growth paths for Indonesia's industrial sector using SAM (social accounting matrix) multiplier analysis and CGE (computable general equilibrium) modeling. The context of the analysis is the immediate post-crisis period — most likely to be in the next millennium — represented in our study by a modified benchmark data set for 1995. Special attention is given to the overall income and equity effects, considering that egalitarian growth has become a particularly important development objective in Indonesia. The results of SAM multiplier analysis indicate relatively strong macro-linkages from agricultural demand-led (ADL) industrialization, yielding a significantly larger increase in real GDP compared to that arising from industrial development oriented to either food processing or light manufacturing. The simulation results based on CGE modeling, which take account of nonlinearities and supply constraints that are ignored in SAM analysis, bear out the dominant influence of demand linkages in showing that ADL industrialization is associated with a larger GDP increase than the two industrial-led development paths.

description: Radiative and non-radiative electron spin flip probabilities are analysed in both plane wave and focussed laser backgrounds. We provide a simple and physically transparent description of spin dynamics in plane waves, and demonstrate that there exists a kinematic regime in which the usual leading order perturbative hierarchy of QED is reversed, and non-radiative loop effects dominate over radiative tree-level spin-flips. We show that while this loop-dominance becomes suppressed in focussed laser pulses due to a high sensitivity to field geometry, there is nevertheless a regime in which, in principle, loop effects on spin transitions can be discerned.

description: In developing theories of nuclear binding energy such as density-functional theory, the effort required to make a fit can be daunting due to the large number of parameters that may be in the theory and the large number of nuclei in the mass table. For theories based on the Skyrme interaction, the effort can be reduced considerably by using the singular value decomposition to reduce the size of the parameter space. We find that the sensitive parameters define a space of dimension four or so, and within this space a linear refit is adequate for a number of Skyrme parameters sets from the literature. We do not find marked differences in the quality of the fit between the SLy4, the Bky4 and SkP parameter sets. The r.m.s. residual error in even-even nuclei is about 1.5 MeV, half the value of the liquid drop model. We also discuss an alternative norm for evaluating mass fits, the Chebyshev norm. It focuses attention on the cases with the largest discrepancies between theory and experiment. We show how it works with the liquid drop model and make some applications to models based on Skyrme energy functionals. The Chebyshev norm seems to be more sensitive to new experimental data than the root-mean-square norm. The method also has the advantage that candidate improvements to the theories can be assessed with computations on smaller sets of nuclei.

description: The regulator of the canonical Wnt pathway, leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), is expressed in the stem cell compartment of several tissues and overexpressed in different human carcinomas. The isoform of the stem cell marker LGR5, named LGR5Δ5 and first described by our group, is associated with prognosis and metastasis in oral squamous cell carcinoma (OSCC) and soft tissue sarcoma (STS). In a proof-of-principle analysis, the function of LGR5Δ5 was investigated in HEK293T cells, a model cell line of the Wnt pathway, compared to full-length LGR5 (FL) expression. The CRISPR/CAS knockout of LGR5 and LGR4 (thereby avoiding the side effects of LGR4) resulted in a loss of Wnt activity that cannot be restored by LGR5Δ5 but by LGR5FL rescue. The ability to migrate was not affected by LGR5Δ5, but was reduced by LGR5FL overexpression. The CRISPR/CAS of LGR4 and 5 induced radiosensitization, which was enhanced by the overexpression of LGR5FL or LGR5Δ5. RNA sequencing analysis revealed a significant increase in the ligand R-spondin 1 (RSPO1) level by LGR5Δ5. Furthermore, LGR5Δ5 appears to be involved in the regulation of genes related to the cytoskeleton, extracellular matrix stiffness, and angiogenesis, while LGR5FL is associated with the regulation of collagens and histone proteins.

description: Hierarchical mergers are one of the distinctive signatures of binary black hole (BBH) formation through dynamical evolution. Here, we present a fast semi-analytic approach to simulate hierarchical mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs). Hierarchical mergers are more common in NSCs than they are in both GCs and YSCs, because of the different escape velocity. The mass distribution of hierarchical BBHs strongly depends on the properties of first-generation BBHs, such as their progenitor's metallicity. In our fiducial model, we form black holes (BHs) with masses up to $\sim{}10^3$ M$_\odot$ in NSCs and up to $\sim{}10^2$ M$_\odot$ in both GCs and YSCs. When escape velocities in excess of 100 km~s$^{-1}$ are considered, BHs with mass $>10^3$ M$_\odot$ are allowed to form in NSCs. Hierarchical mergers lead to the formation of BHs in the pair instability mass gap and intermediate-mass BHs, but only in metal-poor environments. The local BBH merger rate in our models ranges from $\sim{}10$ to $\sim{} 60$ Gpc$^{-3}$ yr$^{-1}$; hierarchical BBHs in NSCs account for $\sim{}10^{-2}- 0.2$ Gpc$^{-3}$ yr$^{-1}$, with a strong upper limit of $\sim{}10$ Gpc$^{-3}$ yr$^{-1}$. When comparing our models with the second gravitational-wave transient catalog, we find that multiple formation channels are favored to reproduce the observed BBH population.

description: A logarithmic scaling for structure functions, in the form $S_p \sim [\ln (r/η)]^{ζ_p}$, where $η$ is the Kolmogorov dissipation scale and $ζ_p$ are the scaling exponents, is suggested for the statistical description of the near-dissipation range for which classical power-law scaling does not apply. From experimental data at moderate Reynolds numbers, it is shown that the logarithmic scaling, deduced from general considerations for the near-dissipation range, covers almost the entire range of scales (about two decades) of structure functions, for both velocity and passive scalar fields. This new scaling requires two empirical constants, just as the classical scaling does, and can be considered the basis for extended self-similarity.

description: Application layer multicast shows its efficiency when it is necessary to transmit enormous amount of data to many nodes. One of the most important issues for such kind of transmission is ”what is the criteria for path construction?”. In the global networks, when the distance between nodes becomes a significant f actor, the time delay between nodes seems self-evident. However, in the presence of cross-traffic in the c hannel, the minimum spanning tree based on the delay might construct the tree which provides the lower data rate than possible alternative. The point of this work is to study how available bandwidth estimation techniques might solve such kind of challenges, how to adopt available bandwidth as a metric to construct data distribution paths and the cases when it gives higher performance in comparison with delay as a metric.

description: We use a modified version of the Peak Patch excursion set formalism to compute the mass and size distribution of QCD axion miniclusters from a fully non-Gaussian initial density field obtained from numerical simulations of axion string decay. We find strong agreement with N-Body simulations at a significantly lower computational cost. We employ a spherical collapse model and provide fitting functions for the modified barrier in the radiation era. The halo mass function at $z=629$ has a power-law distribution $M^{-0.6}$ for masses within the range $10^{-15}\lesssim M\lesssim 10^{-10}M_{\odot}$, with all masses scaling as $(m_a/50μ\mathrm{eV})^{-0.5}$. We construct merger trees to estimate the collapse redshift and concentration mass relation, $C(M)$, which is well described using analytical results from the initial power spectrum and linear growth. Using the calibrated analytic results to extrapolate to $z=0$, our method predicts a mean concentration $C\sim \mathcal{O}(\text{few})\times10^4$. The low computational cost of our method makes future investigation of the statistics of rare, dense miniclusters easy to achieve.

description: In this study, a dynamically recursive general equilibrium model of Morocco is used to examine alternative trade and domestic policy scenarios involving the implementation of the EU Association Agreement for the period 1998-2012. The model has a detailed treatment of the agricultural and rural economy in Morocco. The results for the trade liberalization scenarios indicate that tariff unification has small aggregate effects whereas the removal of non-tariff barriers has strong positive aggregate effects: factor incomes and household welfare expand considerably more rapidly than for the base. However, trade liberalization disfavors the rural poor, especially in rainfed areas. We simulate the introduction of complementary domestic policies with a non-distorting transfer program that fully compensates the owners of rainfed resources and skill upgrading for the rural labor force. The results indicate that, if combined with at least one of these complementary domestic policies, trade liberalization can lead to a win-win outcome: the welfare of all household groups increases significantly more rapidly than if status-quo policies are followed.

We identify a natural notion of periodicity for such shifts and study their C*-algebras. We prove the algebras generated by all shifts of a fixed period are of Cuntz-Krieger and Toeplitz-Cuntz-Krieger type. The limit C*-algebras determined by an increasing sequence of positive integers, each dividing the next, are proved to be isomorphic to Cuntz-Pimsner algebras and the linking maps are shown to arise as factor maps. We derive a characterization of simplicity and compute the $K$-groups for these algebras. We prove a classification theorem for the class of algebras generated by simple loop graphs.

description: Playfulness is an individual difference variable that enables people to experience and (re)frame situations of everyday life as interesting, entertaining, and/or stimulating. This definition is consistent with a structural model that includes four different playfulness facets: other-directed, lighthearted, intellectual, and whimsical playfulness. In the work context, playfulness has been shown to be related with various outcomes such as innovative behavior or intrinsic goals. We tested adult playfulness' associations with coping strategies employed at work and whether these coping strategies help to transfer the expected association between playfulness and employees' life satisfaction. Study 1 (N = 185; nursery school trainees) provides support for our hypothesis that playfulness is associated with more positive and less negative coping strategies when being confronted with general and work-specific stress. Study 2 (N = 355; employees from various working fields) confirms our results from study 1 by demonstrating that playfulness is related to adaptively coping with work stress. Further, study 2 shows that some playfulness facets were positively related to life satisfaction and that these associations were transferred by coping less negatively with work stress and, to some degree, also by utilizing positive control strategies. Overall, our findings indicate that adults' playfulness is of importance for coping with stress at work and to further explain employees’ life-satisfaction. Directions for future research on playfulness in the work place are discussed.

description: Changes in real wages are often used to measure welfare changes. There is a problem, however, in interpreting measures of changes in factor returns when analyzing the impact of changes in taxes — such as tariffs and indirect taxes — that operate as wedges in product and factor markets versus direct taxes that do not work through the price system. One must account for both how the tax is collected and where the tax revenue goes. We sort out how a shift in tax structure will affect the real wage in a model which isolates the price, wage, revenue, and welfare effects. We start from a simple general equilibrium model which accounts for all income and expenditure flows in the economy and includes both traded and domestic goods. We analyze the impact of changes in indirect taxes and tariffs on prices and factor income and demonstrate the pitfalls of using real factor returns as a welfare indicator. There is a transfer effect on factor returns arising from any shift between indirect and direct taxes, regardless of any efficiency effects. Next, we add explicit factor markets to the model and describe the implications for income distribution in an extension of the Jones trade model. We find that the transfer effect dampens the magnification effect of a price change on factor returns, but does not reverse the Stolper-Samuelson results.

description: Aim: To revise Pinus pinaster-dominated communities of the Italian peninsula with special regard to central-southern Tuscany, and assess their floristic and ecological differences. Study area: Tuscany and Liguria regions, Italy. Methods: We classified 251 vegetation plots using the Two-way indicator species analysis method and we explored vegetation patterns through Principal Coordinate Analysis. We then investigated the ecology using Ecological Indicator Values. Results: We identified four major groups, primarily distinguished by the substrate of their stands and along a latitudinal gradient. We classified the forests in central-southern Tuscany in the association Erico scopariae-Pinetum pinastri. This community includes thermophilous and mesophilous species primarily distributed in the Atlantic and Western Mediterranean regions. Comparison of community means of Ecological Indicator Values revealed significant differences in soil reaction, nitrogen, moisture, and light conditions, but not in temperature, between the central-southern Tuscany forests and the other clusters. We classified the other studied forest communities on acidic substrates within the association Erico arboreae-Pinetum pinastri, whereas those found on ultramafic substrates were placed in the Euphorbio ligusticae-Pinetum pinastri typus cons. propos., and in an informal group of secondary vegetation stands. Conclusions: Our analyses showed that the Pinus pinaster-dominated forests of central-southern Tuscany belong to the association Erico scopariae-Pinetum pinastri of the alliance Genisto pilosae-Pinion pinastri (class Pinetea halepensis). The presence of species of phytogeographical importance in the forest understory, underscores the high biogeographic and conservation value of these pine forests.

description: We present new important results about the intermediate-type Seyfert galaxy Mrk 315, recently observed through optical imaging and integral-field spectroscopy. Broad-band images were used to study the morphology of the host galaxy, narrow-band H-alpha images to trace the star forming regions, and middle-band [O III] images to evidence the distribution of the highly ionised gas. Some extended emission regions were isolated and their physical properties studied by means of flux calibrated spectra. High resolution spectroscopy was used to separate different kinematic components in the velocity fields of gas and stars. Some peculiar features characterise this apparently undisturbed and moderately isolated active galaxy. Such features, already investigated by other authors, are re-analysed and discussed in the light of these new observations. The most relevant results we obtained are: the multi-tiers structure of the disc; the presence of a quasi-ring of regions with star formation much higher than previous claims; a secondary nucleus confirmed by a stellar component kinematically decoupled by the main galaxy; a new hypothesis about the controversial nature of the long filament, initially described as hook-shaped, and more likely made of two independent filaments caused by interaction events between the main galaxy and two dwarf companions.

description: The results of liberalization studies can be influenced decisively by the methodology of import tariff aggregation. This article deals with different measures used to aggregate import tariffs. Therefore, the advantages and disadvantages of different aggregation measures are discussed theoretically. In the empirical part of the paper, the simple average and the trade-weighted average of bound and applied tariffs are calculated for different agricultural products of the EU. The analysis considers ad valorem and specific tariffs as well as tariff rate quotas. Additionally, for the applied tariffs, a distinction is made between MFN-tariffs and bilateral preferential tariff rates. Using the same data base, the product specific Trade Restrictiveness Index (TRI) and the Mercantilist Trade Restrictiveness Index (MTRI) are calculated. Because of the poor data availability at the detailed tariff-line level, a simple partial equilibrium application of these indices is implemented, which can be extended to the whole import tariff data base of an economic trade model. The results show a strong correlation between all aggregation methods, but the size of the import tariffs differs highly, depending on the aggregation measure used. Furthermore, high differences between bound and applied tariffs for some EU agricultural products are calculated.

description: Complex electrical permittivity measurements in (1-x)[Pb(Mg1/3 Nb2/3)O3]-xPbTiO3 ceramics for 0.10 x 0.40 were performed in the frequency and temperature range from 1 kHz to 100 kHz and from 15 to 600 K, respectively. Unexpected dielectric anomalies, which were frequency dependent, were found at cryogenic temperatures. It was verified that this dielectric behavior is always observed, independently of whether the composition presents a "normal" ferroelectric or a relaxor characteristic. The results were analyzed within the framework of two current models found in the literature. It was concluded that none of the proposed mechanisms uniquely satisfies the experimental results in the composition range investigated here.

description: Context: Branching has been widely adopted in version control to enable collaborative software development. However, the isolation caused by branches may impose challenges on the upcoming merging process. Recently, companies like Google, Microsoft, Facebook, and Spotify, among others, have adopted trunk-based development together with feature toggles. This strategy enables collaboration without the need for isolation through branches, potentially reducing the merging challenges. However, the literature lacks evidence about the benefits and limitations of feature toggles to collaborative software development. Objective/Method: In this paper, we study the effects of applying feature toggles on 949 open-source projects written in 6 different programming languages. We first identified the moment in which each project adopted a feature toggles framework. Then, we observed whether the adoption implied significant changes in the frequency or complexity of branch merges and the number of defects, and the average time to fix them. Finally, we compared the obtained results with results obtained from a set of control projects that do not use feature toggles frameworks. Results/Conclusion: We could observe a reduction in the average merge effort and an increase in the average total time needed to fix defects after adopting feature toggles frameworks. However, we could not confirm that this increase was influenced by the use of feature toggles.

description: In the article, the first generation of apple trees bears fruit, few in number, and its harm is not pronounced much. Severe damage to the apple tree during the development of 2-4 generations of fruiting occurred in the second decade of August, in the variety “white rosemary” the lesion decreased by 2.3% in the first decade of September. “G.It has been established that the varieties ”dileshes “ and ” Starksimon " are strongly affected by the apple fruit pest. During the summer, the apple tree bears fruit for three generations in the Kibrai district of the Tashkent region and 2-3 generations in mountainous areas. The female butterfly is a prolific apple tree and lays from 30 to 120 eggs, depending on climatic conditions and the type of fruit tree.
Trade Reform and the Poor in Morocco: A Rural-Urban General Equilibrium Analysis of Reduced Protection

description: Morocco is currently about to start reducing industrial protection in the context of its association agreement with the European Union. However, agriculture, which represents the major income source for the disfavored rural population, is the sector that is most strongly protected. In this study, a general equilibrium model of Morocco is used as a laboratory for analyzing the short-run equilibrium effects of alternative scenarios for reduced protection for agriculture and industry. The model, which is calibrated to a Social Accounting Matrix for 1994, is distinguished by an explicit separation of activities, factors, and households into rural and urban. It has a detailed treatment of agricultural and other rural production, the labor market, and households (disaggregated into four types: rural poor, rural non-poor, urban poor, urban non-poor). The simulation results indicate that reduced agricultural protection would generate significant aggregate welfare gains at the same time a significant part of the disadvantaged rural population would lose strongly. The impact of industrial tariff cuts is small. The outcome is less unfavorable for rural households over a slightly longer time frame where labor migration between agriculture, the rest of the rural economy and urban areas is feasible. The results for simulations that introduce compensatory measures targeting the rural population suggest that the dilemma presented by the tradeoff between aggregate and rural welfare can be overcome: in simulations introducing trade liberalization together with government transfers to owners of rainfed agricultural resources, or moderate improvements in rural skill levels or productivity in rural non-agriculture, the gains from trade liberalization are shared relatively evenly among all household groups.

description: A family of orthonormal bases of ultrametric wavelets in the space of quadratically integrable with respect to arbitrary measure functions on general (up to some topological restrictions) ultrametric space is introduced. Pseudodifferential operators (PDO) on the ultrametric space are investigated. We prove that these operators are diagonal in the introduced bases of ultrametric wavelets and compute the corresponding eigenvalues. Duality between ultrametric spaces and directed trees is discussed. In particular, a new way of construction of ultrametric spaces by completion of directed trees is proposed.
