description: Coronavirus disease 2019 (COVID-19) is an emerging disease that was first reported in Wuhan city, the capital of Hubei province in China, and has subsequently spread worldwide. Risk factors for mortality have not been well summarized. Current meta-analysis of retrospective cohort studies was done to summarize available findings on the association between age, gender, comorbidities and risk of death from COVID-19 infection. Online databases including Web of Science, PubMed, Scopus, Cochrane Library and Google scholar were searched to detect relevant publications up to 1 May 2020, using relevant keywords. To pool data, random-effects model was used. Furthermore, sensitivity analysis and publication bias test were also done. In total, 14 studies with 29,909 COVID-19 infected patients and 1445 cases of death were included in the current meta-analysis. Significant associations were found between older age (≥65 vs <65 years old) (pooled ORs = 4.59, 95%CIs = 2.61–8.04, p p = .021) and risk of death from COVID-19 infection. In addition, hypertension (pooled ORs = 2.70, 95%CIs = 1.40–5.24, p = .003), cardiovascular diseases (CVDs) (pooled ORs = 3.72, 95%CIs = 1.77–7.83, p = .001), diabetes (pooled ORs = 2.41, 95%CIs = 1.05–5.51, p = .037), chronic obstructive pulmonary disease (COPD) (pooled ORs = 3.53, 95%CIs = 1.79–6.96, p p Older age (≥65 years old), male gender, hypertension, CVDs, diabetes, COPD and malignancies were associated with greater risk of death from COVID-19 infection. These findings could help clinicians to identify patients with poor prognosis at an early stage.

description: Cavity-free optical nonreciprocity components, which have an inherent strong asymmetric interaction between the forward- and backward-propagation direction of the probe field, are key to produce such as optical isolators and circulators. According to the proposal presented by Xia et al., [Phys. Rev. Lett. 121, 203602 (2018)], we experimentally build a device that uses cross-Kerr nonlinearity to achieve a cavity-free optical isolator and circulator. Its nonreciprocal behavior arises from the thermal motion of N-type configuration atoms, which induces a strong chiral cross-Kerr nonlinear response for the weak probe beam. We obtain a two-port optical isolator for up to 20 dB of isolation ratio in a specially designed Sagnac interferometer. The distinct propagation directions of the weak probe field determine its cross-phase shift and transmission, by which we demonstrate the accessibility of a four-port optical circulator.

description: Insulin-like growth factor-1 (IGF-1) is an anabolic hormone, the levels of which decline with age. The present study aimed to determine the impact of age-related declines in serum IGF-1 levels on various physiological processes. We retrospectively reviewed the medical records of patients whose serum IGF-1 levels were estimated in our department, and assessed the relationships between serum IGF-1 levels and various physiological parameters. A total of 427 patients with a mean (± standard deviation) age of 52.8 (± 17.1) years were included in the analysis. The levels of serum IGF-1 showed significant positive correlation with those of hemoglobin and hematocrit, and negative correlation with the presence of inflammatory and fibrin-related markers including C-reactive protein (CRP) and procalcitonin (PCT), and D-dimer and fibrin degradation products (FDP). These tendencies persisted after exclusion of patients with pituitary disease. In this study population of diverse diseases and backgrounds, a decline in serum IGF-1 levels with age was associated with an increase in inflammatory and fibrin-related markers. This may explain the correlation between low serum IGF-1 levels and an increased risk of cardiovascular events. Our findings suggest that serum IGF-1 is a clinically relevant marker of cardiovascular risk, particularly in males.

description: Collisions between heavy atomic nuclei at ultra-relativistic energies are carried out at particle colliders to produce the quark-gluon plasma, a state of matter where quarks and gluons are not confined into hadrons, and colour degrees of freedom are liberated. This state is thought to be produced as a transient phenomenon before it fragments into thousands of particles that reach the particle detectors. Despite two decades of investigations, one of the big open questions is to obtain an experimental determination of the temperature reached in a heavy-ion collision, and a simultaneous determination of another thermodynamic quantity, such as the entropy density, that would give access to the number of degrees of freedom. Here we obtain the first such determination, utilizing state-of-the-art hydrodynamic simulations. We define an effective temperature, averaged over the space-time evolution of the medium. Then, using experimental data, we determine this temperature, the corresponding entropy density and speed of sound in the matter created in lead-lead collisions at the Large Hadron Collider. Our results agree with first-principles calculations from lattice quantum chromodynamics and confirm that a deconfined phase of matter is indeed produced.

description: Features of farmers' professional cooperatives in China are introduced. The establishment of these organizations is spontaneous. Their operation shows self-government. And their targets are highly pertinent. Then, I analyze the existing problems in farmers' professional cooperatives and vacancy of government functions. These cooperatives are single in content, narrow in service field, not scientific in management mode, and low in efficiency. In addition, government policy support is not put in place for these cooperatives. In view of these situations, firstly, it is proposed to speed up construction of service-oriented government at grass-roots level and promote development of farmers' professional cooperatives. Secondly, it is suggested to set up awareness of service-oriented government and enhance guidance and service for farmers' professional cooperatives. Thirdly, we should increase financial support and guide these organizations to achieve a benign development. Fourthly, we should strengthen propaganda to raise popularity and influence power of these organizations. Fifthly, it is recommended to make clear the guidance and leading functions of regional supply and marketing cooperatives to raise service efficiency. Finally, we should establish scientific evaluation and incentive system to push forward healthy development of farmers' professional cooperatives.

A Model for the Strings of Eta Carinae
Creators: name: Soker, Noam
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose a model based on ionization shadows to explain the formation of the long and narrow strings of Eta Carinae. Five strings are known, all located along the symmetry axis outside the Homunculus. The model assumes that each string is formed in a shadow behind a dense clump near the symmetry axis. The surrounding gas is ionized first, becomes much hotter, and compresses the gas in the shadow. This leads to the formation of a radial, dense, long, and narrow region, i.e., a string. Later the neutral material in the strings is ionized, and becomes brighter. Still later it re-expands, and we predict that in about 200 years the strings will fade. The condition for the model to work is that the ionization front, due to the diffuse ionizing recombination radiation of the surrounding gas, proceeds into the shadow at a velocity slower than the compression speed. From that we get a condition on the mass loss rate of the mass loss episode that formed the strings, which should be less than 10^{-4} Mo/year. The model can also explain the strings in the planetary nebula NGC 6543.

A broad second-order phase transition between two dynamical regimes is observed as a function of the tilt angle $θ$. For low $θ$ values, a block motion is observed. For high $θ$ values, the velocity profile becomes curved and a shear velocity gradient appears in the flow.

description: Skeletal muscle is an important site for storing proteins and providing general physical function. Recent research has shown that muscle strength decreases earlier than muscle mass decreases, as shown during the aging process. Our article aimed to compare the association between testosterone levels and grip strength to provide an earlier biomarker to detect muscle weakness. We adopted quartile-based analysis by dividing handgrip power into quartiles, with all participants in the lowest quartile serving as the reference group. Linear regression analysis was conducted between handgrip power and testosterone. Logistic regression models were used to analyze the longitudinal correlation between testosterone levels and the presence of low muscle strength. Serum testosterone levels had a significant correlation with grip strength in all models (p p In conclusion, our study highlighted that testosterone levels are related to greater grip strength.

The evolution of a new cell type was associated with competition for a signaling ligand

Publisher: name: Carnegie Mellon University

description: There is presently a very limited understanding of the mechanisms that underlie the evolution of new cell types. The skeleton-forming primary mesenchyme cells (PMCs) of euechinoid sea urchins, derived from the micromeres of the 16-cell embryo, are an example of arecently evolved cell type. All adult echinoderms have a calcite-based endoskeleton, a synapomorphy of the Ambulacraria. Only euechinoids have a micromere-PMC lineage, however, which evolved through the co-option of the adult skeletogenic program into theembryo. During normal development, PMCs alone secrete the embryonic skeleton. Othermesoderm cells, known as blastocoelar cells (BCs), have the potential to produce a skeleton, but a PMC-derived signal ordinarily prevents these cells from expressing a skeletogenicfate and directs them into an alternative developmental pathway. Recently, it was shownthat vascular endothelial growth factor (VEGF) signaling plays an important role in PMC differentiation and is part of a conserved program of skeletogenesis among echinoderms.Here, we report that VEGF signaling, acting through ectoderm-derived VEGF3 and its cognate receptor, VEGF receptor (VEGFR)-10-Ig, is also essential for the deployment of theskeletogenic program in BCs. This VEGF-dependent program includes the activation ofaristaless-like homeobox 1 (alx1), a conserved transcriptional regulator of skeletogenicspecification across echinoderms and an example of a “terminal selector” gene that controlscell identity. We show that PMCs control BC fate by sequestering VEGF3, thereby preventing activation of alx1 and the downstream skeletogenic network in BCs. Our findings providean example of the regulation of early embryonic cell fates by direct competition for asecreted signaling ligand, a developmental mechanism that has not been widely recognized. Moreover, they reveal that a novel cell type evolved by outcompeting other embryoniccell lineages for an essential signaling ligand that regulates the expression of a gene controlling cell identity.

 Described from Vietnam, the abovementioned records in the collection CEHI are included here as they are the first ones known since the description of tonkinensis and represent therefore also a new record for the Chinese fauna.
 Habitus, size, and colouration of A. tonkinensis are very close to A. spinicollis Jakovlev 1880, known from several provinces of China (Heiss 2001b, 2010); it can be confounded with the latter. In tonkinensis the antennae are more slender and relatively longer (compare Figs. 20,21 with Figs. 22,23 and Photos 3 and 4), the preocular acute tubercle is longer, and the paranota are more expanded and dentate; the scutellum is distinctly constricted at its posterior half and the posterolateral angles of dorsal external laterotergites (deltg) are more produced, particularly in the female.

description: Weak gravitational lensing is one of the most promising cosmological probes to constrain dark matter, dark energy, and the nature of gravity at cosmic scales. Intrinsic alignments (IAs) of galaxies have been recognized as one of the most serious systematic effects facing gravitational lensing. Such alignments must be isolated and removed to obtain a pure lensing signal. Furthermore, the alignments are related to the processes of galaxy formation, so their extracted signal can help in understanding such formation processes and improving their theoretical modeling. We report in this Letter the first detection of the gravitational shear--intrinsic shape (GI) correlation and the intrinsic shape--galaxy density (Ig) correlation using the self-calibration method in a photometric redshift survey. These direct measurements are made from the KiDS-450 photometric galaxy survey with a significance of 3.65$σ$ in the third bin for the Ig correlation, and 3.51$σ$ for the GI cross-correlation between the third and fourth bins. The self-calibration method uses the information available from photometric surveys without needing to specify an IA model and will play an important role in validating IA models and IA mitigation in future surveys such as the Rubin Observatory Legacy Survey of Space and Time, Euclid, and WFIRST.

description: We present a study of the broadband UBV color profiles for 257 Sbc barred and non-barred galaxies. In our sample, the color gradients are negative (reddish inward) in approximately 59% of the objects, are almost null in 27%, and are positive in 14%, considering only the face-on galaxies, which represent approximately 51% of the sample. We have also found that barred galaxies are over-represented among the objects having null or positive gradients, indicating that bars act as a mechanism of homogenization of the stellar population. A correlation between the total and bulge colors was found, which is a consequence of an underlying correlation between the colors of bulges and disks found by others. Moreover, the mean total color is the same irrespective of the gradient regime, while bulges are bluer in galaxies with null or positive gradients, which indicates an increase of the star formation rate in the central regions of these objects. We found no correlation between color and O/H abundance gradients. We discuss this result considering a picture in which bars are a relatively fast recurrent phenomenon. These results are not compatible with a pure classical monolithic scenario for bulge and disk formation. On the contrary, they favor a scenario where both these components are evolving in a correlated process, in which stellar bars play a crucial role.(Abridged)

description: In the on-line file-caching problem problem, the input is a sequence of requests for files, given on-line (one at a time). Each file has a non-negative size and a non-negative retrieval cost. The problem is to decide which files to keep in a fixed-size cache so as to minimize the sum of the retrieval costs for files that are not in the cache when requested. The problem arises in web caching by browsers and by proxies. This paper describes a natural generalization of LRU called Landlord and gives an analysis showing that it has an optimal performance guarantee (among deterministic on-line algorithms). The paper also gives an analysis of the algorithm in a so-called ``loosely'' competitive model, showing that on a ``typical'' cache size, either the performance guarantee is O(1) or the total retrieval cost is insignificant.

description: In this paper, we investigate thermophysical characteristics of near-Earth asteroid (341843) 2008 EV5, based on our improved Advanced Thermal Physical Model (ATPM) by considering the contribution of sunlight-reflection for rough surface, along with four wavebands observations from Wide-field Infrared Survey Explorer (WISE) and the radar-derived shape model. Here we derive that 2008 EV5 has a relatively low thermal inertia of $Γ=110 _{-12}^{+40}\rm~J m^{-2} s^{-1/2} K^{-1}$ but a high roughness fraction. The geometric albedo and effective diameter are then constrained to be $p_v=0.095_{-0.003}^{+0.016}$ and $D_{\rm eff}=431_{-33}^{+6}\rm~m$, respectively. The low thermal inertia indicates that 2008 EV5 may have undergone sufficient space weathering over secular evolution. The high roughness may have resemblances to the appearances of Bennu and Ryugu recently observed by spacecrafts, where a great number of boulders are widely distributed on the asteroid's surface. Moreover, we numerically perform 1000 backward simulations of 2008 EV5's cloned orbits within 1 Myr to explore its origin, and present a probability of $\sim6.1\%$ that the asteroid originates from the main belt. Finally, we estimate that the mean grain size of the surface ranges from 0.58 to 1.3 mm, and infer that it is unlikely to find water ice on most area of 2008 EV5, but there may exist water ice on high-latitudes near polar region.

 Material of Praocis rotundata Lacordaire studied by Lacordaire (MNHUB) (Fig. 2): two specimens, with labels: [14903] [Hist.-Coll. (Coleoptera)/ Nr. 14903/ Praocis rotundata Lacord. / Coquimbo, Melly (data error)/ Zool. Mus. Berlin] [rotundata / Lacord./ Chili. Dej.] [Praocis / punctata Sol. / det. H. Kulzer 1957].
 Holoype of Praocis soror Kulzer (NHMB): [Villavicenzio/ Mendoza / 3-11-52] [Argentinien / leg. Wittmer] [Holotypus / Praocis / soror m./ det. H. Kulzer 1957] (Fig. 3).
 Comments. Due to the misidentification of Solier (1840), who put Praocis rotundata Lacordaire in synonymy with Praocis sulcata, all the subsequent authors (listed above) assigned this species as inhabiting Chile. We remove Praocis rotundata Lacordaire from the Chilean fauna and based on the examined material (IADIZA, LEULS) we determine its geographical distribution as Mendoza and San Juan provinces of Argentina, being endemic to the Uspallata-Calingasta altitudinal valley between 1400 and 3630 m, in the biogeographic provinces of Monte, Altoandean, and Puna (Roig Juñent et al. 2003). The type locality “Paramillos de Uspallata” is located within this area, in the Precordillera at 3000 m, and it is part of the currently so-called “Reserva Villavicencio”.
 The aforementioned two specimens of Praocis rotundata Lacordaire (MNHUB) were previously determined by Kulzer as Praocis punctata Solier, which is indeed a different species. Praocis punctata Solier has elytra with carinae weakly demarcated and lateral margin of pronotum with a row of long, golden setae (syntypes seen in MNHN). On the other hand, these specimens of Praocis rotundata and the holotype of Praocis soror have elytra with carinae well demarcated and elevated and lateral margin of pronotum glabrous (Figs. 2–3).

description: We study the anomalous elasticity of nematic elastomers by employing the powers of renormalized field theory. Using general arguments of symmetry and relevance, we introduce a minimal Landau-Ginzburg-Wilson elastic energy for nematic elastomers. Performing a diagrammatic low temperature expansion, we analyze the fluctuations of the displacement fields at and below the upper critical dimension 3. Our analysis reveals an anomaly of certain elastic moduli in the sense that they depend on the length scale. In $d = 3$ this dependence is logarithmic and below $d=3$ it is of power law type with anomalous scaling exponents. One of the 4 relevant shear moduli vanishes at long length scales whereas the only relevant bending modulus diverges.

description: The goal of the Sloan Digital Sky Survey is ``to map in detail one-quarter of the entire sky, determining the positions and absolute brightnesses of more than 100 million celestial objects''. The survey will be performed by taking ``snapshots'' through a large telescope. Each snapshot can capture up to 600 objects from a small circle of the sky. This paper describes the design and implementation of the algorithm that is being used to determine the snapshots so as to minimize their number. The problem is NP-hard in general; the algorithm described is a heuristic, based on Lagriangian-relaxation and min-cost network flow. It gets within 5-15% of a naive lower bound, whereas using a ``uniform'' cover only gets within 25-35%.

 Material examined: ♂ ♀♀ China, Hainan, Changjiang / Bawangling 2006. V. 3 Bai X.S. / Ent. Mus. CAU Beijing // Aradus / wuzhisanensis / Liu, 1981 / det. Bai Xiaoshuan 2007 // Aradus / candidatus / Bergroth / det. E. Heiss 2009 (CAU, 1♂ 1♀ CEHI).
 When examining the type material of Aradus candidatus Bergroth 1889, which was described upon specimens from Burma (Myanmar), the habitus of both sexes and genitalic structures of the male were figured (Heiss 1989). Dissecting now male specimens of wuzhisanensis for the study of the unknown genitalic structures (Fig.1–5, 7–11) EH noted that they are not different from those of candidatus. This was then confirmed by comparing it with further candidatus specimens from Thailand and Laos, which showed also no differences in wuzhisanensis in general aspect, colouration, structure of antennae, and male genitalia. The record from Hainan Province extends the known distribution area of SE Asian mainland eastward; it may be expected that this species occurs also in other countries like Cambodia and Vietnam or even in southern mainland China.
 Therefore we propose the following synonymy: Aradus candidatus Bergroth 1889 = Aradus wuzhisaneneis Liu 1981, new synonymy.

title: Chemical, morphological, and rheological properties of various rejuvenated asphalt binders

description: Reclaimed asphalt pavement (RAP) material is considered as an economical approach for sustainable pavement construction. However, usage of higher RAP binder content is more susceptible to pavement cracking. Using rejuvenators with RAP binder is a widely used approach to address the issues related to RAP binder. This study used thin film oven test (TFOT) aged binder with three types of rejuvenators including waste cooking oil (UT/R1), modified waste cooking oil (TR/R2), and Hydrolene (HL/R3). Also, in some cases, styrene butadiene styrene (SBS) polymer was added with UT/R1 and TR/R2 rejuvenated binders to compare the performances. To understand the behavior and the performance of these rejuvenators, three sets of characterization tests were conducted: chemical, morphological, and rheological. Gas Chromatography-Mass Spectroscopy (GC-MS) and Fourier Transformed Infrared Spectroscopy (FTIR) was employed for chemical characterization, while Atomic Force Microscopy (AFM) was used for morphological analysis. Later, a frequency sweep test and surface free energy (SFE) test was conducted to understand the rheological performances and moisture damage resistance of rejuvenated asphalt binders respectively. Based on the experimentation, the study reveals that UT/R1 softens the binders most, whereas TR/R2 rejuvenator eliminates these issues and showed better rheological performances of the binder. However, in case of moisture susceptibility, TR/R2 rejuvenated binder seems to have poor resistance and the highest resistance was recorded for UT/R1 rejuvenated binders. This study observes a good correlation between chemical, morphological and rheological performances of binders which are expected to contribute to the performance evaluation and characterization of rejuvenated asphalt mixes.

description: Finding the optimal signal timing strategy is a difficult task for the problem of large-scale traffic signal control (TSC). Multi-Agent Reinforcement Learning (MARL) is a promising method to solve this problem. However, there is still room for improvement in extending to large-scale problems and modeling the behaviors of other agents for each individual agent. In this paper, a new MARL, called Cooperative double Q-learning (Co-DQL), is proposed, which has several prominent features. It uses a highly scalable independent double Q-learning method based on double estimators and the UCB policy, which can eliminate the over-estimation problem existing in traditional independent Q-learning while ensuring exploration. It uses mean field approximation to model the interaction among agents, thereby making agents learn a better cooperative strategy. In order to improve the stability and robustness of the learning process, we introduce a new reward allocation mechanism and a local state sharing method. In addition, we analyze the convergence properties of the proposed algorithm. Co-DQL is applied on TSC and tested on a multi-traffic signal simulator. According to the results obtained on several traffic scenarios, Co- DQL outperforms several state-of-the-art decentralized MARL algorithms. It can effectively shorten the average waiting time of the vehicles in the whole road system.

description: Panicle density of cereal crops such as wheat and sorghum is one of the main components for plant breeders and agronomists in understanding the yield of their crops. To phenotype the panicle density effectively, researchers agree there is a significant need for computer vision-based object detection techniques. Especially in recent times, research in deep learning-based object detection shows promising results in various agricultural studies. However, training such systems usually requires a lot of bounding-box labeled data. Since crops vary by both environmental and genetic conditions, acquisition of huge amount of labeled image datasets for each crop is expensive and time-consuming. Thus, to catalyze the widespread usage of automatic object detection for crop phenotyping, a cost-effective method to develop such automated systems is essential. We propose a point supervision based active learning approach for panicle detection in cereal crops. In our approach, the model constantly interacts with a human annotator by iteratively querying the labels for only the most informative images, as opposed to all images in a dataset. Our query method is specifically designed for cereal crops which usually tend to have panicles with low variance in appearance. Our method reduces labeling costs by intelligently leveraging low-cost weak labels (object centers) for picking the most informative images for which strong labels (bounding boxes) are required. We show promising results on two publicly available cereal crop datasets - Sorghum and Wheat. On Sorghum, 6 variants of our proposed method outperform the best baseline method with more than 55% savings in labeling time. Similarly, on Wheat, 3 variants of our proposed methods outperform the best baseline method with more than 50% of savings in labeling time.
