description: An analysis of the Kimura 3ST model of DNA sequence evolution is given on the basis of its continuous Lie symmetries. The rate matrix commutes with a U(1)xU(1)xU(1) phase subgroup of the group GL(4) of 4x4x4 invertible complex matrices acting on a linear space spanned by the 4 nucleic acid base letters. The diagonal `branching operator' representing speciation is defined, and shown to intertwine the U(1)xU(1)xU(1) action. Using the intertwining property, a general formula for the probability density on the leaves of a binary tree under the Kimura model is derived, which is shown to be equivalent to established phylogenetic spectral transform methods.

Berlin’s Cosmopolitan Production Culture

description: Through the first decades of the 21st century, the Berlin-Brandenburg region has become an important production location, first for international films and then, most recently, also for transnational tele­vision drama series. Since 2015, more than 20 transnational TV drama series were produced in the region. Berlin has been attracting talent from all over the world, becoming a hotspot for international production where both above and below-the line talents from different countries work together in a creative and productive way. In this article, I argue that Berlin has thus successfully established a cosmopolitan production culture. In what follows, I outline the cosmopolitan conditions that underpin Berlin’s production culture and the creative collaboration of talent with different cultural backgrounds.

description: We present a deep learning method for single-station earthquake location, which we approach as a regression problem using two separate Bayesian neural networks. We use a multi-task temporal-convolutional neural network to learn epicentral distance and P travel time from 1-minute seismograms. The network estimates epicentral distance and P travel time with absolute mean errors of 0.23 km and 0.03 s respectively, along with their epistemic and aleatory uncertainties. We design a separate multi-input network using standard convolutional layers to estimate the back-azimuth angle, and its epistemic uncertainty. This network estimates the direction from which seismic waves arrive to the station with a mean error of 1 degree. Using this information, we estimate the epicenter, origin time, and depth along with their confidence intervals. We use a global dataset of earthquake signals recorded within 1 degree (~112 km) from the event to build the model and to demonstrate its performance. Our model can predict epicenter, origin time, and depth with mean errors of 7.3 km, 0.4 second, and 6.7 km respectively, at different locations around the world. Our approach can be used for fast earthquake source characterization with a limited number of observations, and also for estimating location of earthquakes that are sparsely recorded -- either because they are small or because stations are widely separated.

Glocality and Cosmopolitanism in European Crime Narratives

Publisher: name: Akademisk kvarter/Academic Quarter
Year: 2021

description: As an introduction to this issue of Academic Quarter, the article offers a few reflections on how the notions of glocalism and cosmopolitanism can help frame the transcultural significance of one of the most popular narrative genres of the last decades – crime fiction. Stemming in part from the research conducted in the frame of the European Union’s Horizon 2020 DETECt project, the articles in this issue explore whether or not European crime fiction, in its different literary, audio-visual and transmedia manifestations, has been contributing to shape a cosmopolitan culture across the continent. Since the fall of the Berlin Wall in 1989, the European crime genre has increasingly exploited the diversity of European cultures and landscapes to create engaging narratives able to travel transnationally. In so doing, it has become one of the clearest examples of today’s glocal culture, but the question remains of whether its celebration of local singularities on a global scale has concretely promoted the generation of cosmopolitan identities able to transcend the barriers that national and linguistic boundaries keep maintaining between different countries and communities.

description: Macrodactylus suavis Bates, 1887
 Diagnosis. This species is distinguished by the following combination of characters: antennal club reddish­brown with the apex darkened; pronotum black with scattered scalelike setae mainly toward the borders of disc; scutellum with abundant, yellow, scale­like setae; elytra with numerous scale­like setae along the inner half and short setae distributed in two irregular stripes along the outer half, basal half reddish­brown and apical half black (Fig. 4); pygidium black, dark brown or reddish­yellow with scattered scale­like setae near the center of disc; abdomen black; femora and tibiae reddish­brown, apex of tibiae darkened; tarsi black without white setae; parameres with lanceolate apex, without setae on the external borders; female vestiture and color similar to male.
 Material examined (2 males, 1 female) NICARAGUA: Chontales, Belt, male syntype (CNC). COSTA RICA: San José province, San Antonio, Quebrada Londres, 1700 m, 17 May 1997, Col. F. A. Quezada, 1 male, 1 female (MXAL).
 Biology. This species inhabits wet montane forests located at altitudes from 800 to 1700 m. Month of collection: May (2).
 Distribution. Southern Nicaragua to central Panama (8° 50'– 12° 10' N, 79° 30'– 85° 20' W).
 Remarks. This species was originally described with specimens from “ Costa Rica;” Volcán de Irazú, Cache, Costa Rica; Bugaba, Panama; and Chontales, Nicaragua. Bates noted the variation of large body size (11 mm) and dark color of the middle and hind tibiae in the specimens from Chontales. Worn specimens are difficult to identify without the examination of male genitalia, because the distribution of setae on the elytra is an important diagnostic character.

Year: 1980
Subjects: Farm Management

description: Analysis of structure in American agriculture often overlooks both the subtle and complex differences among farms of varying sizes within a relatively small production area. The resource components of farms of various sizes significantly affect the size and crop mix structure of each group of farms. To examine this structure-sampled farms have been grouped using cluster analysis-. The multivariate data observations are grouped without preconceived hypotheses. Statistical analysis of the results reveal that farms group somewhat by size and crop mix. However, smaller farms do vary substantially in composition from larger farms and avoid significant production of risk-oriented crops.
A three-phase approach to grain surface chemistry in protoplanetary disks: Gas, ice surfaces and ice mantles of dust grains
Creators: name: Ruaud, Maxime

Year: 2019
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We study the effects of grain surface reactions on the chemistry of protoplanetary disks where gas, ice surface layers and icy mantles of dust grains are considered as three distinct phases. Gas phase and grain surface chemistry is found to be mainly driven by photo-reactions and dust temperature gradients. The icy disk interior has three distinct chemical regions: (i) the inner midplane with low FUV fluxes and warm dust ($\gtrsim 15$K) that lead to the formation of complex organic molecules, (ii) the outer midplane with higher FUV from the ISM and cold dust where hydrogenation reactions dominate and, (iii) a molecular layer above the midplane but below the water condensation front where photodissociation of ices affects gas phase compositions. Some common radicals, e.g., CN and C$_2$H, exhibit a two-layered vertical structure and are abundant near the CO photodissociation front and near the water condensation front. The 3-phase approximation in general leads to lower vertical column densities than 2-phase models for many gas-phase molecules due to reduced desorption, e.g., H$_2$O, CO$_2$, HCN and HCOOH decrease by $\sim$ two orders of magnitude. Finally, we find that many observed gas phase species originate near the water condensation front; photo-processes determine their column densities which do not vary significantly with key disk properties such as mass and dust/gas ratio.

description: The hard X-ray transient source Swift J1845.7-0037 was discovered in 2012 by Swift/BAT. However, at that time no dedicated observations of the source were performed. On Oct 2019 the source became active again, and X-ray pulsations with a period of ~199s were detected with Swift/XRT. This triggered follow-up observations with NuSTAR. Here we report on the timing and spectral analysis of the source properties using NuSTAR and Swift/XRT. The main goal was to confirm pulsations and search for possible cyclotron lines in the broadband spectrum of the source to probe its magnetic field. Despite highly significant pulsations with period of 207.379(2) were detected, no evidence for a cyclotron line was found in the spectrum of the source. We therefore discuss the strength of the magnetic field based on the source flux and the detection of the transition to the "cold-disc" accretion regime during the 2012 outburst. Our conclusion is that, most likely, the source is a highly magnetized neutron star with B 1e13G at a large distance of d~10 kpc. The latter one consistent with the non-detection of a cyclotron line in the NuSTAR energy band.

Risk and Uncertainty

description: Macartney rose is a range management problem on approximately 500,000 acres of highly productive rangeland in southeast Texas. Roller chopping followed by prescribed burning is an economically effective treatment. However, there is a relatively high degree of risk associated with implementation of an effective burn. A methodology is developed to account for this uncertainty in a linear programming model designed to select optimal burning schedules. Model results indicate that consideration of uncertainty substantially affects net returns and optimal burning schedules. Low probabilities of successful burns produce law net returns and optimal burning schedules with frequent burning. Higher probabilities result in higher returns and less frequent burning.

description: A recently obtained extension (xncKP) of the Moyal-deformed KP hierarchy (ncKP hierarchy) by a set of evolution equations in the Moyal-deformation parameters is further explored. Formulae are derived to compute these equations efficiently. Reductions of the xncKP hierarchy are treated, in particular to the extended ncKdV and ncBoussinesq hierarchies. Furthermore, a good part of the Sato formalism for the KP hierarchy is carried over to the generalized framework. In particular, the well-known bilinear identity theorem for the KP hierarchy, expressed in terms of the (formal) Baker-Akhiezer function, extends to the xncKP hierarchy. Moreover, it is demonstrated that N-soliton solutions of the ncKP equation are also solutions of the first few deformation equations. This is shown to be related to the existence of certain families of algebraic identities.

description: Nowadays, interactive technologies are used almost everywhere. As a result, designers need to increasingly make them "socially acceptable". Previous work recommends "subtle" forms of interaction to increase social acceptability and avoid negative experiences. Although often appropriate, such uniform recommendations neglect the variety of social situations. We demonstrate this limitation in an experiment (N=35), by comparing the observer experience of different forms of interaction in "face-to-face conversations", a social situation rarely studied. Here, the typically recommended form of interaction ("subtle") led to a more negative observer experience than the usually deprecated form ("suspenseful"), in terms of affective experience and product perception. It also made the user appear less extraverted. We conclude by positioning interactions with technology not as separate from the social situation in which they are performed, but as a constitutive part of it that meaningfully relates to other situated activities.

description: Hyperspectral images (HSI) classification is a high technical remote sensing tool. The main goal is to classify the point of a region. The HIS contains more than a hundred bidirectional measures, called bands (or simply images), of the same region called Ground Truth Map (GT). Unfortunately, some bands contain redundant information, others are affected by the noise, and the high dimensionalities of features make the accuracy of classification lower. All these bands can be important for some applications, but for the classification a small subset of these is relevant. In this paper we use mutual information (MI) to select the relevant bands; and the Normalized Mutual Information coefficient to avoid and control redundant ones. This is a feature selection scheme and a Filter strategy. We establish this study on HSI AVIRIS 92AV3C. This is effectiveness, and fast scheme to control redundancy. Index Terms: Hyperspectral images, Classification, Feature Selection, Normalized Mutual Information, Redundancy.

description: flatoxins and fumonisins are two major mycotoxins: toxic chemicals produced by fungi that contaminate a variety of food commodities including maize, a key staple food in sub-Saharan Africa. Aflatoxin causes liver cancer (hepatocellular carcinoma, HCC) and has been associated with acute liver toxicity and immunotoxicity, while fumonisin has been associated with neural tube defects in infants and esophageal cancer. Both mycotoxins have been associated with child growth impairment. Previous studies have demonstrated that co-occurrence of these mycotoxins may have potential synergistic toxicological effects in humans. Therefore, this study examines the occurrence and co-occurrence of fumonisin and aflatoxin along the maize value chain in southwest Nigeria. Despite regulatory limits in Nigeria for aflatoxins in maize products, 51.70% of the samples were found had aflatoxin levels above those limits. Though no regulatory limits currently exist for fumonisins, 12.93% of the samples contained total fumonisin levels higher than the United States regulatory limit. We found that aflatoxin and fumonisin contamination in maize products extends beyond production to storage and final food products. Thus, adequately addressing the mycotoxin challenge requires consideration of the entire maize value chain. This study encourages further research to generate data on the exposure of Nigerians to fumonisin and aflatoxin and potential adverse health effects.

description: Large probabilistic models are often shaped by a pool of known individuals (a universe) and relations between them. Lifted inference algorithms handle sets of known individuals for tractable inference. Universes may not always be known, though, or may only described by assumptions such as "small universes are more likely". Without a universe, inference is no longer possible for lifted algorithms, losing their advantage of tractable inference. The aim of this paper is to define a semantics for models with unknown universes decoupled from a specific constraint language to enable lifted and thereby, tractable inference.

description: We investigate quasi-periodic pulsations (QPPs) of high-energy nonthermal emissions from an X9.3 flare (SOL2017-Sep-06T11:53), the most powerful flare since the beginning of solar cycle 24. The QPPs are identified as a series of regular and repeating peaks in the light curves in the gamma- and hard X-ray (HXR) channels recorded by the Konus-Wind, as well as the radio and microwave fluxes measured by the CALLISTO radio spectrograph during the impulsive phase. The periods are determined from the global wavelet and Fourier power spectra, as 24-30 s in the HXR and microwave channels which are associated with nonthermal electrons, and ~20 s in the gamma-ray band related to nonthermal ions. Both nonthermal electrons and ions may be accelerated by repetitive magnetic reconnection during the impulsive phase. However, we could not rule out other mechanisms such as the MHD oscillation in a sausage mode. The QPP detected in this study is useful for understanding the particle acceleration and dynamic process in solar flares and also bridging the gap between stellar and solar flares since the energy realm of the X9.3 solar flare is almost compared with a typical stellar flare.

description: We report findings from the first set of data in a current survey to establish conclusively whether jets from young stars rotate. We observed the bi-polar jets from the T Tauri stars TH28 and RW Aur, and the blue-shifted jet from T Tauri star LkH$α$321, using the Hubble Space Telescope Imaging Spectrograph (HST/STIS). Forbidden emission lines (FELs) show distinct and systematic velocity asymmetries of 10 -- 25 (+/- 5) km/s at a distance of 0".3 from the source, representing a (projected) distance of ~ 40 AU along the jet in the case of RW Aur, ~ 50 AU for TH28, and 165 AU in the case of LkH$α$321. These velocity asymmetries are interpreted as rotation in the initial portion of the jet where it is accelerated and collimated. For the bi-polar jets, both lobes appear to rotate in the same direction. Values obtained were in agreement with the predictions of MHD disk-wind models (Bacciotti et al 2002, Anderson et al 2003, Dougados et al 2003, Pesenti et al 2003). Finally, we determine, from derived toroidal and poloidal velocities, values for the distance from the central axis of the footpoint for the jet's low velocity component of ~ 0.5 - 2 AU, consistent with the models of magneto-centrifugal launching (Anderson et al 2003).

Optimization of light structures: the vanishing mass conjecture

description: We consider the shape optimization problem which consists in placing a given mass $m$ of elastic material in a design region so that the compliance is minimal. Having in mind optimal light structures, our purpose is to show that the problem of finding the stiffest shape configuration simplifies as the total mass $m$ tends to zero: we propose an explicit relaxed formulation where the compliance appears after rescaling as a convex functional of the relative density of mass. This allows us to write necessary and sufficient optimality conditions for light structures following the Monge-Kantorovich approach developed recently in [5].

description: • Sweet potato yields have increased over the past decade partly due to introduction of improved high yielding varieties but yields still fall short of the potential. • Some of the factors constraining productivity growth include over-recycling of seed among farmers and poor agronomic practices due to limited extension services. • The release of Orange Fleshed Sweet Potato (OFSP) varieties have contributed to decline in Vitamin A deficiency in Malawi, contributing to improved nutrition status. • Demand for sweet potato and associated products is increasing partly due to increased urbanization and vulnerability of maize to climate change impacts. • To improve Malawi’s sweet potato value chain, the following recommendations are made: significant investments in seed systems, irrigation, post-harvest, value addition and agro-processing technologies in response to identified market and industry needs; investments in research and extension on improved varieties, good agronomic practices, and pest and diseases prevention and control; and investments to link farmers, farmer organizations and processors through contract farming arrangements and scaling up of Orange-Fleshed Sweet Potato (OFSP) varieties to maintain sufficient Vitamin A intake.

 Diagnosis. This species is distinguished by the following combination of characters: antennal club entirely yellowish­brown; pronotum iridescent black or dark green with scattered scale­like setae along the midline and on the borders of disc; scutellum with abundant, yellow, scale­like setae; elytra orange­yellow with sericeous shine, glabrous except for 5–6 stout, long black setae near scutellum (Fig. 6); pygidium dark brown or reddish­yellow, with scattered scale­like setae along the center of disc; abdomen black; femora and tibiae reddish­brown, apex of tibiae darkened; tarsi black without white setae; parameres widened, stout, with acute apex, and without setae on the external borders; female vestiture and color similar to male.
 Material examined (2 males, 2 females) NICARAGUA: Chontales, Belt, male syntype (CNC). COSTA RICA: Guanacaste province, Arenal, Tilaran A.C., Tierras Morenas, 685 m, June 1994, Col. G. Rodríguez, 1 male, 1 female (MXAL); Alajuela province, San Ramón de Dos Rios, 620 m, 26 June 1995, Col. F. A. Quezada, 1 female (IEXA).
 Biology. This species inhabits wet montane forests located at altitudes from 620 to 800 m. Month of collection: June (3).
 Distribution. Southern Nicaragua to central Panama (8° 50'– 12° 10' N, 79° 30'– 85° 20' W).
 Remarks. This species was originally described with specimens from Chontales, Nicaragua and Bugaba, Panama. Bates noted the variation of color in the pygidium, which is dark brassy in the specimens from Chontales and yellow in the specimens from Bugaba. The form of the parameres is clearly different to the other species from Mexico to Nicaragua and in combination with other set of characters support the diagnosis of the fifth group of species in the genus. This group will be diagnosed and defined in a future publication.

description: The poultry sub-sector in Nigeria is experiencing rapid growth and transformation. However, heat stress associated with climate change is a challenge to poultry farmers due to its negative effect on chicken growth and productivity Small poultry farmers tend to invest in traditional strategies such as stocking local breeds Medium and large poultry farmers adopt modern technologies such as air and water ventilation and bulbs that emit less heat Farmers who have experienced heat related losses are more likely to adopt modern practices (water ventilation, pay for litter spreading, buy medicines and vitamins or use energy efficient bulb) and more likely to adopt multiple adaptation strategies.

description: Controlling interfacial interactions in magnetic/topological insulator heterostructures is a major challenge for the emergence of novel spin-dependent electronic phenomena. As for any rational design of heterostructures that rely on proximity effects, one should ideally retain the overall properties of each component while tuning interactions at the interface. However, in most inorganic interfaces interactions are too strong, consequently perturbing, and even quenching, both the magnetic moment and the topological surface states at each side of the interface. Here we show that these properties can be preserved by using ligand chemistry to tune the interaction of magnetic ions with the surface states. By depositing Co-based porphyrin and phthalocyanine monolayers on the surface of Bi$_2$Te$_3$ thin films, robust interfaces are formed that preserve undoped topological surface states as well as the pristine magnetic moment of the divalent Co ions. The selected ligands allow us to tune the interfacial hybridization within this weak interaction regime. These results, which are in stark contrast with the observed suppression of the surface state at the first quintuple layer of Bi$_2$Se$_3$ induced by the interaction with Co phthalocyanines, demonstrate the capability of planar metal-organic molecules to span interactions from the strong to the weak limit.

Prolonging Network Lifetime in Wireless Sensor Networks with Path-Constrained Mobile Sink
Creators: name: Mamalis, Basilis
Publisher: name: arXiv
Year: 2019
Subjects: subject: Distributed, Parallel, and Cluster Computing (cs.DC)
subject: FOS: Computer and information sciences

description: Many studies in recent years have considered the use of mobile sinks (MS) for data gathering in wireless sensor networks (WSN), so as to reduce the need for data forwarding among the sensor nodes (SN) and thereby prolong the network lifetime. Moreover, in practice, often the MS tour length has to be kept below a threshold, usually due to timeliness constraints on the sensors data (delay-critical applications). This paper presents a modified clustering and data forwarding protocol combined with a MS solution for efficient data gathering in wireless sensor networks (WSNs) with delay constraints. The adopted cluster formation method is based in the 'residual energy' of the SNs and it is appropriately modified in order to fit properly to the requirement of length-constrained MS tour, which involves, among else, the need for inter-cluster communication and increased data forwarding. In addition, a suitable data gathering protocol is designed, based on an approximated TSP route that satisfies the given length constraint, whereas the proper application of reclustering phases guarantees the effective handling of the 'energy holes' caused around the CHs involved in the MS route. Extended simulation experiments show the stable and energy-efficient behavior of the proposed scheme (thus leading to increased network lifetime) as well as its higher performance in comparison to other competent approaches from the literature.
