description: We apply a universal normal Calabi-Yau algebra to the construction and classification of compact complex $n$-dimensional spaces with SU(n) holonomy and their fibrations. This algebraic approach includes natural extensions of reflexive weight vectors to higher dimensions and a `dual' construction based on the Diophantine decomposition of invariant monomials. The latter provides recurrence formulae for the numbers of fibrations of Calabi-Yau spaces in arbitrary dimensions, which we exhibit explicitly for some Weierstrass and K3 examples.

It is not that funny. Critical analysis of racial ideologies embedded in racialized humour discourses on social media in Brazil
Creators: name: Trindade, Luiz Valério Paula

description: Previous studies reveal that reported cases of racism on Facebook in Brazil have soared from 2,038 cases in 2011 to 11,090 in 2014. This phenomenon has triggered growing concerns amongst several social actors and the Brazilian society at large. Within this context, this qualitative study employs critical discourse analysis to investigate the embedded meanings of the construction and dissemination of colonial-like racialized discourses against Black Brazilians on social media. For this purpose, 217 public Facebook pages and 224 news articles have been gathered, combined with eight interviews conducted with different social actors in Brazil. The data reveals that 81 percent of the victims of online racism are upwardly-mobile Black women aged 20-35 years, whilst 65.6 percent of the proponents of such ideologies are young men in their early twenties. Moreover, in 76.2 percent of the cases analysed, the proponents had no previous relationship with the victims. Therefore, I argue that different from ordinary daily social interactions, the technology enables these people to disregard any social distance that might exist between themselves and the victims. Furthermore, since they believe that online anonymity shields them from being held accountable for their attitude; they have no crise de conscience in disseminating their racialized discourses. This scenario suggests that they have turned social media in a sort of modern-day pillory to perform virtual whipping through derogatory humour posts and associated comments. Within that, the study also reveals that such derogatory discourses tend to develop a long tail, meaning that potentially, the posts can keep attracting like-minded people for the same derogatory conversation for around three years. On the other hand, I also argue that Black women in Brazil have understood the possibilities that social media can afford them. Consequently, they are using the technology to convey their political position and, on top of that, amplify the reach of their voice in ways that in the offline context would be more difficult to achieve. Within that, they are managing to decentralise the Brazilian anti-racist discourse, inspire other oppressed women and establish new empowering communities both online and offline to deconstruct ingrained racist ideologies.

description: The origin of the star forming main sequence ( i.e., the relation between star formation rate and stellar mass, globally or on kpc-scales; hereafter SFMS) remains a hotly debated topic in galaxy evolution. Using the ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) survey, we show that for star forming spaxels in the main sequence galaxies, the three local quantities, star-formation rate surface density (\sigsfr), stellar mass surface density (\sigsm), and the \h2~mass surface density (\sigh2), are strongly correlated with one another and form a 3D linear (in log) relation with dispersion. In addition to the two well known scaling relations, the resolved SFMS (\sigsfr~ vs. \sigsm) and the Schmidt-Kennicutt relation (\sigsfr~ vs. \sigh2; SK relation), there is a third scaling relation between \sigh2~ and \sigsm, which we refer to as the `molecular gas main sequence' (MGMS). The latter indicates that either the local gas mass traces the gravitational potential set by the local stellar mass or both quantities follow the underlying total mass distributions. The scatter of the resolved SFMS ($σ\sim 0.25$ dex) is the largest compared to those of the SK and MGMS relations ($σ\sim$ 0.2 dex). A Pearson correlation test also indicates that the SK and MGMS relations are more strongly correlated than the resolved SFMS. Our result suggests a scenario in which the resolved SFMS is the least physically fundamental and is the consequence of the combination of the SK and the MGMS relations.

Strong decays of the lowest bottomonium hybrid within an extended Born-Oppenheimer framework

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We analyze the decays of the theoretically predicted lowest bottomonium hybrid $H(1P)$ to open bottom two-meson states. We do it by embedding a quark pair creation model into the Born-Oppenheimer framework which allows for a unified, QCD-motivated description of bottomonium hybrids as well as bottomonium. A new $^{1}\!P_{1}$ decay model for $H(1P)$ comes out. The same analysis applied to bottomonium leads naturally to the well-known $^{3}\!P_{0}$ decay model. We show that $H(1P)$ and the theoretically predicted bottomonium state $Υ(5S)$, whose calculated masses are close to each other, have very different widths for such decays. A comparison with data from $Υ(10860)$, an experimental resonance whose mass is similar to that of $Υ(5S)$ and $H(1P)$, is carried out. Neither a $Υ(5S)$ nor a $H(1P)$ assignment can explain the measured decay widths. However, a $Υ(5S)$-$H(1P)$ mixing may give account of them supporting previous analyses of dipion decays of $Υ(10860)$ and suggesting a possible experimental evidence of $H(1P)$.

A general definition of $JT_a$ -- deformed QFTs

Year: 2019
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We propose a general path-integral definition of two-dimensional quantum field theories deformed by an integrable, irrelevant vector operator constructed from the components of the stress tensor and those of a $U(1)$ current. The deformed theory is obtained by coupling the original QFT to a flat dynamical gauge field and "half" a flat dynamical vielbein. The resulting partition function is shown to satisfy a geometric flow equation, which perfectly reproduces the flow equations for the deformed energy levels that were previously derived in the literature. The S-matrix of the deformed QFT differs from the original S-matrix only by an overall phase factor that depends on the charges and momenta of the external particles, thus supporting the conjecture that such QFTs are UV complete, although intrinsically non-local. For the special case of an integrable QFT, we check that this phase factor precisely reproduces the change in the finite-size spectrum via the Thermodynamic Bethe Ansatz equations.

description: Purpose: Children with cochlear implants (CIs) are more likely to struggle with spoken language than their age-matched peers with normal hearing (NH), and new language processing literature suggests that these challenges may be linked to delays in spoken word recognition. The purpose of this study was to investigate whether children with CIs use language knowledge via semantic prediction to facilitate recognition of upcoming words and help compensate for uncertainties in the acoustic signal.Method: Five- to 10-year-old children with CIs heard sentences with an informative verb (draws) or a neutral verb (gets) preceding a target word (picture). The target referent was presented on a screen, along with a phonologically similar competitor (pickle). Children’s eye gaze was recorded to quantify efficiency of access of the target word and suppression of phonological competition. Performance was compared to both an age-matched group and vocabulary-matched group of children with NH.Results: Children with CIs, like their peers with NH, demonstrated use of informative verbs to look more quickly to the target word and look less to the phonological competitor. However, children with CIs demonstrated less efficient use of semantic cues relative to their peers with NH, even when matched for vocabulary ability.Conclusions: Children with CIs use semantic prediction to facilitate spoken word recognition but do so to a lesser extent than children with NH. Children with CIs experience challenges in predictive spoken language processing above and beyond limitations from delayed vocabulary development. Children with CIs with better vocabulary ability demonstrate more efficient use of lexical-semantic cues. Clinical interventions focusing on building knowledge of words and their associations may support efficiency of spoken language processing for children with CIs.

description: There is much debate about the employment effect of shale gas development, especially as it relates to extraction counties. Anecdotal evidence suggests that many of the jobs created are filled by nonresidents. We examine the impact shale gas development has on local employment in Pennsylvania using a data set that links workers to their personal residences. We find that activity in the Marcellus shale has had a modest positive impact on job growth. The impact is cut in half, however, when we use data for county residents only. Thus, traditional employment data may overestimate employment impacts from shale development.

description: Methicillin-resistant Staphylococcus aureus (MRSA) causes a variety of healthcare-associated and community-acquired infections. Due to limited availability of effective antimicrobials for treating MRSA infections, there is a growing need to explore alternative therapeutic approaches. Here, the antimicrobial activities of 19 oils, popularly used for their medicinal properties, were tested against MRSA USA300. Oils obtained from cinnamon, clove, tangerine, and coriander showed the most promising activities, demonstrating bactericidal, anti-adhesive and anti-biofilm activities, and synergistic properties with common antibiotics. Given that clove and cinnamon oils showed the best activities, they were incorporated into topical formulations. Not only did the formulations with oils maintain antimicrobial and anti-adhesive activities, but their anti-biofilm property was potentiated. Tests on Galleria mellonella larvae suggested that the formulation is non-toxic. The formulations proposed here are a great alternative for the decolonisation of surfaces containing MRSA and can help circumventing antimicrobial resistance, a growing threat in the hospital environment.

description: We report on a mid-infrared mode-locked fiber laser that uses an acousto-optic tunable filter to achieve frequency-shifted feedback pulse generation with frequency tuning over a 215 nm range. The laser operates on the 3.5 $μ$m transition in erbium-doped zirconium fluoride-based fiber and utilizes the dual-wavelength pumping scheme. Stable, self-starting mode-locking with a minimum pulse duration of 53 ps was measured using a two-photon absorption autocorrelator. The longest wavelength demonstrated was 3612 nm and a maximum average power of 208 mW was achieved. This is the longest wavelength rare-earth doped mode-locked fiber laser demonstrated to the best of the authors' knowledge. The broad tunability promises potential uses for environmental sensing applications.

description: We evaluate the two pion decay of the Roper resonance in a model where explicit re-scattering of the two final pions is accounted for by the use of unitarized chiral perturbation theory. Our model does not include an explicit $ε$ or $σ$ scalar-isoscalar meson decay mode, instead it generates it dynamically by means of the pion re-scattering. The two ways, explicit or dynamically generated, of introducing this decay channel have very different amplitudes. Nevertheless, through interference with the other terms of the model we are able to reproduce the same phenomenology as models with explicit consideration of the $ε$ meson.

description: Entanglement is a counterintuitive feature of quantum physics that is at the heart of quantum technology. High-dimensional quantum states offer unique advantages in various quantum information tasks. Integrated photonic chips have recently emerged as a leading platform for the generation, manipulation and detection of entangled photons. Here, we report a silicon photonic chip that uses novel interferometric resonance-enhanced photon-pair sources, spectral demultiplexers and high-dimensional reconfigurable circuitries to generate, manipulate and analyse path-entangled three-dimensional qutrit states. By minimizing on-chip electrical and thermal cross-talk, we obtain high-quality quantum interference with visibilities above 96.5% and a maximumly entangled qutrit state with a fidelity of 95.5%. We further explore the fundamental properties of entangled qutrits to test quantum nonlocality and contextuality, and to implement quantum simulations of graphs and high-precision optical phase measurements. Our work paves the path for the development of multiphoton high-dimensional quantum technologies.

description: The genus Helleborus belongs to the Ranunculaceae family, distributed in southeastern Europe and western Asia. In folk medicine, it is commonly used as an anti-inflammatory and analgesic medicine for rheumatoid arthritis and bruises. Through reviewing recent articles, it was found that two hundred and twenty-six compounds have been isolated and identified from the genus Helleborus. These compounds include steroids, flavonoids, phenylpropanoids, lignans, anthraquinones, phenolics and others. Among them, the main chemical constituents are steroids. Pharmacological studies show Helleborus has anti-cancer, immunomodulatory, anti-inflammatory, analgesic, anti-hyperglycaemic, antioxidant and antibacterial properties. This article reviews the botany, phytochemistry, pharmacological effects and clinical applications of the genus Helleborus. Hopefully, it will provide a reference for in-depth research and exploitation of the genus Helleborus.

description: Sinoneta gen. nov.
 Type species. Sinoneta notabilis sp. nov.
 Etymology. The generic name is derived from the Greek word " Sina " (= Chinese) and "- neta " as part of the genus Leptoneta. Gender is feminine.
 Diagnosis. Sinoneta gen. nov. may be recognized by the absence of PME, the pedipalpal tibia subequal to pedipalpal patella in length, the presence of a swollen tuber on base of pedipalpal tibia, the presence of largest and furcated tibial spur I, the complicated pedipalpal bulb and the large median apophysis.
 Description. Dorsal shield of prosoma yellow. Cervical groove and furrows indistinct. Thoracic median groove present. 2 or 4 white eyespots. ALE and PLE arranged in a row, strongly recurved, PME absent. Cheliceral fang furrow with 8 promarginal and 4 or 5 retromarginal teeth. Sternum peltate. Legs long and thin. Leg formula: I-IV-II-III. A cluster of serrated hairs-comb on ventral base of metatarsi II and III respectively. Pedipalpal femur without strong spines, pedipalpal tibia subequal to pedipalpal patella in length. Tibia with modified strong spurs, of them tibial spur I largest, furcate distally and swollen at tibial base. Pedipalpal tarsus rugose, contracted mesially, attached an earlobe-shaped process retrolaterally. Pedipalpal bulb large and rugose area broad, prolateral lobe present, median apophysis sclerotized and multi-furcated distally. Female genitalia with a board atrium and a pair of kinkled spermathecae.
 Composition. Sinoneta gen. nov. includes two species: S. notabilis sp. nov. and S. sexdigiti sp. nov., which occur in caves in Guizhou, southwestern China. The two new members are characterized by being three-clawed, haplogyne, the absence of PME, the vestigial ALE and PLE, the presence of a finely serrated hairs-comb on metatarsi II and III, the chelicerae bearing retrolateral stridulatory ridges and so forth. Apparently they represent a sister group of all other leptonetids yet belong to the family Leptonetidae. In addition, not only S. notabilis sp. nov. and S. sexdigiti sp. nov. have typical characters of the Leptonetidae, they also share the following synapomorphies: 1) the shorter pedipalpal tibia subequal to pedipalpal patella in length, 2) the presence of a proximal furcated large spur on pedipalpal tibia and apparently swollen at ventral base, 3) the developed median apophysis bearing multi-dents at apex. These synapomorphies shared by S. notabilis sp. nov. and S. sexdigiti sp. nov. distinguish the genus from all other leptonetid genera.
 Distribution. Guizhou (China).

description: Purpose: Stuttering is characterized by intermittent speech disfluencies, which are dramatically reduced when speakers synchronize their speech with a steady beat. The goal of this study was to characterize the neural underpinnings of this phenomenon using functional magnetic resonance imaging.Method: Data were collected from 16 adults who stutter and 17 adults who do not stutter while they read sentences aloud either in a normal, self-paced fashion or paced by the beat of a series of isochronous tones (“rhythmic”). Task activation and task-based functional connectivity analyses were carried out to compare neural responses between speaking conditions and groups after controlling for speaking rate.Results: Adults who stutter produced fewer disfluent trials in the rhythmic condition than in the normal condition. Adults who stutter did not have any significant changes in activation between the rhythmic condition and the normal condition, but when groups were collapsed, participants had greater activation in the rhythmic condition in regions associated with speech sequencing, sensory feedback control, and timing perception. Adults who stutter also demonstrated increased functional connectivity among cerebellar regions during rhythmic speech as compared to normal speech and decreased connectivity between the left inferior cerebellum and the left prefrontal cortex.Conclusions: Modulation of connectivity in the cerebellum and prefrontal cortex during rhythmic speech suggests that this fluency-inducing technique activates a compensatory timing system in the cerebellum and potentially modulates top-down motor control and attentional systems. These findings corroborate previous work associating the cerebellum with fluency in adults who stutter and indicate that the cerebellum may be targeted to enhance future therapeutic interventions.

description: A new polysaccharide (AAP) was extracted from Auricularia auricula by water extraction and alcohol precipitation. The antioxidant activity in vitro showed that AAP had a good scavenging effect on ABTS free radicals. Then AAP was purified by DEAE-52 ion exchange chromatography to obtain the purified component pAAP. The structure analysis showed that the molecular weight (Mw) of pAAP was 96.768 kDa, which was composed of rhamnose (Rha), arabinose (Ara), fucose (Fuc), xylose (Xyl), mannose (Man), glucose (Glu) and galactose (Gal), with the ratio of 0.1:0.157:0.33:2.797:2.881:2.988:0.587, and contained α-pyranose configuration and β-pyranose configuration. Field emission scanning electron microscopy and atomic force microscopy revealed the special conformation of pAAP in the ring and chain shape.

description: This paper examines the impact of the seed-fertilizer-irrigation technology (simply the new technology or green revolution) on income distribution and rural poverty in Bangladesh. An agricultural wage determination model is developed for Bangladesh which shows that the new technology has the potential for raising the real wage rate, employment and output, but the impact of the new technology on income distribution between landowners and labourers depends much on whether the technology is labour-saving. Econometric results suggest that although the new technology did not increase the agricultural real wage rate, it lowered the rate of unemployment and underemployment and changed the occupational structure of the labour force, a result of which was the reduction of the incidence of rural poverty in Bangladesh in recent years. Econometric results also suggest that the new technology did not intensify the inequality of income in the rural areas of Bangladesh by raising the incidence of landlessness and near-landlessness.

description: This study explores factors driving tract-level heterogeneity in the quality of leases executed by property owners who transfer their mineral rights to firms that drill for and extract natural gas. The data set consists of tract-level aggregates of lease terms, our measures of lease quality, and tract-level census data from the leases. We find that higher-quality leases are negatively correlated with higher concentration of minority households when controlling for census-tract-level characteristics. Based on the findings, we propose policies to reduce observed heterogeneity in the quality of leases and, subsequently, to reduce residents’ exposure to negative effects of nearby well sites.

description: Galactic binary systems that contain a black hole candidate emit hard X-rays in their low luminosity mode. We show that this emission can be understood as due to the Compton scattering of photons from the companion star and/or the accretion disk by relativistic electrons in a jet. The same electrons are also responsible for the radio emission. Two sources -- XTE J1118+480 and Cygnus X-1 -- are modelled as representatives of black holes with low and high luminosity companion stars respectively. We further show that the ultraluminous compact X-ray sources observed in nearby galaxies have the properties expected of stellar mass black holes with high luminosity companions in which the jet is oriented close to our line of sight.

description: We investigate local economic impacts of shale gas development using the natural experiment of the discontinuity in regulation caused by New York’s 2008 moratorium on fracking. Using county- and zip-code-level data for 2001–2013 to examine differences in New York and Pennsylvania counties before and after the moratorium, we find that shale gas development has a positive local impact on employment and wages in the natural resource, mining, and construction sectors and an offsetting reduction in employment in the manufacturing sector. Overall, we find no statistically significant local effects on total employment or on wages.

However, we note that infinite Bayesian neural networks lack a key facet of the behaviour of real neural networks: the fixed kernel, determined only by network hyperparameters, implies that they cannot do any form of representation learning. The lack of representation or equivalently kernel learning leads to less flexibility and hence worse performance, giving a potential explanation for the inferior performance of infinite networks observed in the literature (e.g. Novak et al. 2019). We give analytic results characterising the prior over representations and representation learning in finite deep linear networks. We show empirically that the representations in SOTA architectures such as ResNets trained with SGD are much closer to those suggested by our deep linear results than by the corresponding infinite network. This motivates the introduction of a new class of network: infinite networks with bottlenecks, which inherit the theoretical tractability of infinite networks while at the same time allowing representation learning.

description: An ethnobotanical documentation on the medicinal plants used by local people of Nagaland (North-east India) has been presented here. The study explored 33 plant species (with their local names, indigenous applications, sources/origins, parts of plants used, bioactive compounds present, process of preparing medicines from the plants) belonging to 28 families have been reviewed thoroughly. Some examples are, Catharanthus roseus (Tsuinrinaro, Periwinkle), Acacia pennata (Chakrangaing, Ballikhadira), Adhatoda vasica (Kicharangnaro, Malabar-nut), Ageratum conzyoides (Imchenriza, Billy-goat-weed,/Tropical-white-weed), Alstonia scholaris (Lazarongpang, Blackboard), Rauvolfia serpentina (Per-mozutong, Indian-snakeroot), etc. Plant based drugs are very popular and effective in Nagaland from ancient times but thorough-documentation with scientific-background of effectiveness, active chemical-compounds present, their action-mechanism, etc., are still scanty. Such review can be of useful for pharmacologist, phyto-chemists to a broad group of researchers and may lead to discovery of new sources of novel medicines through traditional therapeutic knowledge.

description: Sodium-ion batteries (SIBs) have received significant attention as promising alternative for energy storage applications owing to the large availability and low cost of sodium. In this paper we study the electrochemical behavior of Na$_{0.74}$Co$_{1-x}$Nb$_x$O$_2$ ($x=$ 0 and 0.05 samples), synthesized via solid-state reaction. The Rietveld refinement of x-ray diffraction patterns reveals the hexagonal crystal symmetry with P63/mmc space group. The Na$_{0.74}$Co$_{0.95}$Nb$_{0.05}$O$_2$ cathode exhibits a specific capacity of about 91 mAhg$^{-1}$ at a current density of 6 mAg$^{-1}$, whereas Na$_{0.74}$CoO$_2$ exhibits comparatively low specific capacity (70 mAhg$^{-1}$ at a current density of 6 mAg$^{-1}$). The cyclic voltammetry (CV) and electron impedance spectroscopy (EIS) were performed to determine the diffusion coefficient of Na, which found to be in the range of 10$^{-10}$ cm$^2$s$^{-1}$.

description: A field experiment was carried out in the Light village of Netrokona Sadar during the period from December 2010 to March 2011 to study the performance of some wheat varieties in terms of nutrient contents and their uptake. The experiment comprised of five varieties of wheat viz. BARI Gam 25, Shatabdi, BARI Gam 26, Prodip and Bijoy. The experiment was laid out in a randomized complete block design with six replications. The nutrient contents and their uptake by wheat grain and straw were significantly influenced by the varieties. The highest N, P, K, S, Ca, B and Zn contents in grain were found in the variety BARI Gam 26 and the lowest N, K, S, Ca and Mg contents were found in the variety Shatabdi. The maximum N, P and S uptake by grain were recorded in the variety BARI Gam 26. On the other hand, the highest K and Zn uptake by grain were obtained from the variety Prodip. The minimum N, K, S, Ca, Mg and Zn uptake by grain were recorded in the variety Shatabdi. In straw, the maximum N, P, K, S, Ca and B uptake were observed in the variety BARI Gam 26 and the minimum N, K, S, Ca and B uptake were found in the variety BARI Gam 25. On the basis of nutrient contents and their uptake, wheat variety BARI Gam 26 showed the best performance.

description: Forty three rice genotypes were used to evaluate their aroma detection through sensory test. Aroma was detected by 1.7% KOH as a sensory test. Thirteen rice genotypes were detected having strong aroma; ten had moderate aroma; fifteen had slight aroma and five had no aroma. In case of grain shape study, 37 genotypes were evaluated as slender and six as medium. In this study, grain aroma had significant and positive association with grain length width ratio; significant and negative association with grain width, significant and negative association with gelatinization temperature, and significant and negative association with grain length. Gelatinization temperature had significant and negative correlation with grain length, significant and negative association with grain length width ratio, significant and positive association with grain width. Grain length had significant and negative correlation with grain width; significant and positive correlation with length width ratio. Grain width had significant and negative correlation with length width ratio. Finally, it can be concluded that among 43 genotypes Basmati370,CT19541-13-3-1-2P- 1P,PSBRC18,PSB-RC2(IR32809-26-3-3),IR64,IR50,2001059-TR2151-6-1-1,IR64-P401,IR72-P204 were found good grain quality traits having higher physico-chemical attributes. These elite lines could be readily used in breeding programmes to improve grain quality traits.

description: Tribe Tactusini Fibiger, new tribe   Type genus: Tactusa, new genus; type-species Tactusa sumatrensis Fibiger, new species.
 Taxonomic notes. The tribe consists of ten new genera: Tactusa, Conspica, Tumula, Dignus, Vas, Nigerides, Fustis, Bruma, Costasensora, and Longiantrum; altogether with 49 species, one of which has already been described. The descriptions below are intended to reflect the phylogenetic sequence of the genera and species. It is sometimes possible to identify a species of Tactusini from other Micronoctuidae by external characteristics, but at species level, careful examination of the genitalia is always required.
 Diagnosis. Character states of tribe Tactusini with synapomorphies indicated by (apo.) described in detail under subfamily Tactusinae, briefly under genus Tactusa. Most important character of tribe is elongated ampulla, which more or less forms a T with axis of valva (apo.).
 Differential diagnosis. Species of Tactusini differ from those of Obscurini in several character states, e.g. species smaller; ampulla plate more or less circular in Obscurini, elongated in Tactusini, and antrum short.
 Distribution. Tactusini found in tropical, subtropical and temperate areas of E and SE Asian and Oriental regions.
