The interactive effects of various nitrogen fertiliser formulations applied to urine patches on nitrous oxide emissions in grassland
2017
AbstractPasture-based livestock agriculture is a major source of greenhouse gas (GHG) nitrous oxide (N2O). Although a body of research is available on the effect of urine patch N or fertiliser N on N2O emissions, limited data is available on the effect of fertiliser N applied to patches of urinary N, which can cover up to a fifth of the yearly grazed area. This study investigated whether the sum of N2O emissions from urine and a range of N fertilisers, calcium ammonium nitrate (CAN) or urea ± urease inhibitor ± nitrification inhibitor, applied alone (disaggregated and re-aggregated) approximated the N2O emission of urine and fertiliser N applied together (aggregated). Application of fertili…
Extracting multi-mode ERP features using fifth-order nonnegative tensor decomposition
2018
Background Preprocessed Event-related potential (ERP) data are usually organized in multi-way tensor, in which tensor decomposition serves as a powerful tool for data processing. Due to the limitation of computation burden for multi-way data and the low algorithm performance of stability and efficiency, multi-way ERP data are conventionally reorganized into low-order tensor or matrix before further analysis. However, the reorganization may hamper mode specification and spoil the interaction information among different modes. New method In this study, we applied a fifth-order tensor decomposition to a set of fifth-order ERP data collected by exerting proprioceptive stimulus on left and right…

Maldivas y el delicado equilibrio entre India y China
2019
Maldivas es la nación más pequeña de Asia Meridional en términos de población, superficie y PBI. A pesar de ello, este pequeño archipiélago tiene una gran importancia estratégica, en virtud de su ubicación en medio de las rutas marítimas internacionales del océano Índico, y en su cercanía a las costas de la India. La propuesta de este artículo es exponer los cambios que se produjeron en Maldivas durante la presidencia de Abdulla Yameen en cuanto a la política interna, como así también a las relaciones exteriores, y observar en qué momento estas dos tendencias se cruzan para formar parte de una misma trama. A su vez, analizar finalmente las consecuencias que esto tiene para el país y para la…

Retoriskie teksta posmi interneta ziņu rakstos
2016
Ziņas ir viena no svarīgākajām vajadzībām ikdienas dzīvē, lai sekotu līdzi pasaules notikumu attīstībai. Ir veikti vairāki avīžu rakstu pētījumi no dažādiem aspektiem, taču maz uzmanības tiek pievērsts retoriskajiem teksta posmiem avīžu rakstos, kas pieejami internetā, tādēļ šī darba mērķis ir izpētīt retoriskos teksta posmus un to attiecīgo soļus struktūru interneta ziņu rakstos un noteikt to lingvistiskās iezīmes. Darba analīzei, galvenokārt tika izmantotas tādu autoru kā Swales (1990)un Bhatia (1993) teorijas. Iegūtie dati tika analizēti, izmantojot kvalitatīvā pētījuma metodi ar kvantitatīviem elementiem. Analīzei tika izvēlēti divdesmit BBC biznesa interneta ziņu raksti. Pētījuma rezul…
Assessing the Open Trenches in Screening Railway Ground-Borne Vibrations by Means of Artificial Neural Network
2009
Reducing ground borne vibrations in urban areas is a very challenging task in railway transportation. Many mitigation measures can be considered and applied; among these open trenches are very effective. This paper deals with the study of the effect, in terms of reduction of vertical and horizontal displacements and velocities, of the open trenches. 2D FEM simulations have been performed and several open trench configurations have been analysed varying the main geometric features such as width and depth, distance from the rail, thickness of the soil layer over the rigid bedrock, type of the ground, ratio between the depth of the trench, and the thickness of the soil layer. For quantifying t…
Diagnostic delay of oral squamous cell carcinoma and the fear of diagnosis: A scoping review.
2022
The mortality rate of patients affected with oral squamous cell carcinoma (OSCC) has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient’s fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnosti…
Image classification based on 2D feature motifs
2013
The classification of raw data often involves the problem of selecting the appropriate set of features to represent the input data. In general, various features can be extracted from the input dataset, but only some of them are actually relevant for the classification process. Since relevant features are often unknown in real-world problems, many candidate features are usually introduced. This degrades both the speed and the predictive accuracy of the classifier due to the presence of redundancy in the candidate feature set. In this paper, we study the capability of a special class of motifs previously introduced in the literature, i.e. 2D irredundant motifs, when they are exploited as feat…
