Weierstrass semigroups on the Skabelund maximal curve

In 2017, D. Skabelund constructed a maximal curve over $\mathbb{F}_{q^4}$ as a cyclic cover of the Suzuki curve. In this paper we explicitly determine the structure of the Weierstrass semigroup at any point $P$ of the Skabelund curve. We show that its Weierstrass points are precisely the $\mathbb{F}_{q^4}$-rational points. Also we show that among the Weierstrass points, two types of Weierstrass semigroup occur: one for the $\mathbb{F}_q$-rational points, one for the remaining $\mathbb{F}_{q^4}$-rational points. For each of these two types its Ap\'ery set is computed as well as a set of generators

Two-point AG codes from one of the Skabelund maximal curves

In this paper, we investigate two-point Algebraic Geometry codes associated to the Skabelund maximal curve constructed as a cyclic cover of the Suzuki curve. In order to estimate the minimum distance of such codes, we make use of the generalized order bound introduced by P. Beelen and determine certain two-point Weierstrass semigroups of the curve.Comment: 15 page

Efecto de la fragmentación del bosque sobre las fuentes potenciales de alimento para aves en Córdoba

La pérdida y fragmentación del bosque pueden alterar la abundancia de recursos alimentarios queconsumen distintos grupos de aves. Estudiar cómo se relacionan distintos indicadores de la fragmentacióncon la abundancia de alimentos consumidos por una amplia diversidad de aves puede ayudar a entender losefectos indirectos de la fragmentación del bosque sobre sus poblaciones. Trabajamos en fragmentos de bosquechaqueño en Córdoba, Argentina. Estimamos la abundancia relativa de artrópodos, flores, frutos y semillas(alimento para distintos gremios tróficos de aves) en un gradiente de fragmentación, tanto en verano comoen invierno. Durante el verano, Celtis ehrenbergiana y Lycium cestroides ofrecieron más del 90% de los frutos yflores estimados, respectivamente. Durante el invierno, Solanum argentinum aportó casi la totalidad de los frutosornitócoros estimados. La abundancia de artrópodos (durante el invierno) y de semillas (en ambas estaciones)aumentó con la reducción del área de los fragmentos y se observó una mayor abundancia en el borde respectoal interior de los fragmentos. Sólo observamos una relación negativa entre la fragmentación y la abundanciade frutos ornitócoros y flores ornitófilas para algunas especies individuales. Con respecto a la estacionalidad,la abundancia relativa de artrópodos fue significativamente menor durante el invierno, mientras que laabundancia relativa de frutos ornitócoros y semillas en el suelo fue similar entre estaciones. La disminuciónde la abundancia de flores en invierno fue tan drástica que nos imposibilitó realizar comparaciones estadísticas.Este trabajo ofrece una primera aproximación a la abundancia de recursos alimentarios que consumen las avesy su respuesta a la fragmentación en un sector del bosque chaqueño.Fil: Verga, Ernesto Gustavo.

Innovations through 5G-Crosshaul applications

Proceeding of: 2016 European Conference on Networks and Communications (EuCNC) 27-30 junio 2016 Athens, GreeceA transport network for 5G envisions integrating the fronthaul and backhaul segments (namely 5G-Crosshaul) into a single transport network. This requires a fully integrated and unified management of fronthaul and backhaul resources in a sharable, scalable and flexible way. The integrated and unified management of the transport network resources follows the Software Defined Networking (SDN) principles of centralization, decoupling between control and data plane and application ecosystem. Innovation to enable context-aware resource management and to provide system-wide optimization of QoS, as well as energy related objectives, lies on defining key applications as logical decision entities to program the underlying network and packet forwarding behaviour. This paper presents a set of 5G-Crosshaul SDN applications with the scope of (i) managing the 5G-Crosshaul resources, including not only network but also computing and storage resources, and (ii) offering efficient media distribution and traffic offloading solutions. In order to develop these applications in a real system, we identify the interactions between the applications and the control plane. Based on these interactions, we propose a two-layer application plane and specify the requirements of the applications on the Northbound Interface (NBI) of the control plane.This work has been supported by the H2020 project “5G-Crosshaul: The 5G Integrated fronthaul/backhaul” (671598)

Recommendations on complementary feeding for healthy, full-term infants

Weaning (or introduction of complementary feeding) is a special and important moment in the growth of a child, both for the family and the infant itself, and it can play a major role in the child's future health. Throughout the years, various weaning modes have come in succession, the latest being baby-led weaning; the timing for introducing foods and the requirements of which sort of nutrient for weaning have also changed over time. Furthermore, the role played by nutrition, especially in the early stages of life, for the onset of later non-communicable disorders, such as diabetes, obesity or coeliac disease has also been increasingly highlighted. Members of Italian Society of Gastroenterology, Hepathology and Pediatric Nutrition (SIGENP) and the Italian Society of Allergology and Pediatric Immunology (SIAIP) Emilia Romagna here propose a practical approach for pediatricians to deal with daily practice. The four main areas for discussion were weaning in relation with the onset of allergic diseases, coeliac disease, diabetes and metabolic syndrome, the nutrition requirements to take into account for assessing the diet of infants under one year of age and about the practice of baby-led weaning focusing on limits and benefits, respectively

Novel Resource and Energy Management for 5G Integrated Backhaul/Fronthaul (5G-Crosshaul)

The integration of both fronthaul and backhaul into a single transport network (namely, 5G-Crosshaul) is envisioned for the future 5G transport networks. This requires a fully integrated and unified management of the fronthaul and backhaul resources in a cost-efficient, scalable and flexible way through the deployment of an SDN/NFV control framework. This paper presents the designed 5G-Crosshaul architecture, two selected SDN/NFV applications targeting for cost-efficient resource and energy usage: the Resource Management Application (RMA) and the Energy Management and Monitoring Application (EMMA). The former manages 5G-Crosshaul resources (network, computing and storage resources). The latter is a special version of RMA with the focus on the objectives of optimizing the energy consumption and minimizing the energy footprint of the 5G-Crosshaul infrastructure. Besides, EMMA is applied to the mmWave mesh network and the high speed train scenarios. In particular, we present the key application design with their main components and the interactions with each other and with the control plane, and then we present the proposed application optimization algorithms along with initial results. The first results demonstrate that the proposed RMA is able to cost-efficiently utilize the Crosshaul resources of heterogeneous technologies, while EMMA can achieve significant energy savings through energy-efficient routing of traffic flows. For experiments in real system, we also set up Proof of Concepts (PoCs) for both applications in order to perform real trials in the field.© 2017 IEEE. Personal use of this material is permitted.

Dynamical noncommutativity and Noether theorem in twisted phi^*4 theory

A \star-product is defined via a set of commuting vector fields X_a = e_a^\mu (x) \partial_\mu, and used in a phi^*4 theory coupled to the e_a^\mu (x) fields. The \star-product is dynamical, and the vacuum solution phi =0, e_a^\mu (x)=delta_a^\mu reproduces the usual Moyal product. The action is invariant under rigid translations and Lorentz rotations, and the conserved energy-momentum and angular momentum tensors are explicitly derived.Comment: 15 pages LaTeX, minor typos, added reference

Noncommutative geometry and physics: a review of selected recent results

This review is based on two lectures given at the 2000 TMR school in Torino. We discuss two main themes: i) Moyal-type deformations of gauge theories, as emerging from M-theory and open string theories, and ii) the noncommutative geometry of finite groups, with the explicit example of Z_2, and its application to Kaluza-Klein gauge theories on discrete internal spaces.Comment: Based on lectures given at the TMR School on contemporary string theory and brane physics, Jan 26- Feb 2, 2000, Torino, Italy. To be published in Class. Quant. Grav. 17 (2000). 3 ref.s added, typos corrected, formula on exterior product of n left-invariant one-forms corrected, small changes in the Sect. on integratio

CircumMed+Euro pine forest database: an electronic archive for Mediterranean and European forests

Large thematic databases of vegetation-plots are increasingly needed for vegetation studies and biodiversity research. In this paper, we present the CircumMed+Euro Pine Forest Database (GIVD ID: EU-00-026), which in September 2018 encompassed 5590 records from pine-dominated vegetation plots (relevés) and associated vegetation types from 23 countries of temperate Europe, Eastern Mediterranean and North Africa. These vegetation plots were collected through a detailed literature search for plots not included in the European Vegetation Archive (EVA). The database includes plots from 192 bibliographic references and unpublished vegetation plots by different authors. All vegetation plots are georeferenced, and coordinates are available with different accuracy as reported by the authors. The database is managed by the Vegetation Science Group, Department of Botany and Zoology of the Masaryk University in Brno (Czech Republic). It is registered in the Global Index of Vegetation-Plot Databases (GIVD) with the code EU-00-026 and is accessible through the European Vegetation Archive (EVA) or by asking the Custodian. The CircumMed+Euro Pine Forest Database is an important resource for conducting different types of broad-scale studies in the fields of vegetation classification, plant invasion ecology, macroecology and biological conservationN/

Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns
