Intracerebral haemorrhage in a dog with steroid-responsive meningitis arteritis
A one-year and six-month-old female neutered Boxer dog was presented with a four-day history of pyrexia, lethargy and neck pain. An intracerebral haemorrhage and a mediastinal mass were identified. Cerebrospinal fluid analysis revealed severe neutrophilic pleocytosis, and steroid-responsive meningitis arteritis (SRMA) was suspected. A significant improvement was observed with immunosuppressive steroid therapy and subsequent imaging revealed a reduction in size of the intracerebral haemorrhage and disappearance of the mediastinal mass. SRMA is a systemic disease with potential involvement of multiple organs. Intracerebral haemorrhage can occur secondary to SRMA and can have a successful outcome

Distributed multivariate regression with unknown noise covariance in the presence of outliers: an MDL approach
We consider the problem of estimating the coefficients in a multivariable linear model by means of a wireless sensor network which may be affected by anomalous measurements. The noise covariance matrices at the different sensors are assumed unknown. Treating outlying samples, and their support, as additional nuisance parameters, the Maximum Likelihood estimate is investigated, with the number of outliers being estimated according to the Minimum
Description Length principle. A distributed implementation based on iterative consensus techniques is then proposed, and it is shown effective for managing outliers in the data.Peer ReviewedPostprint (author's final draft
Generic Battery Model based on a Parametric Implementation
Batteries are a common element used in many electronic applications. Therefore, the analysis and simulation of these applications requires a battery model in order to validate the behavior of the whole system. Since batteries are based on different technologies, a modeling approach valid for any technology is a potential good alternative. Since there are similarities among the different technologies, it is possible to address the modeling of batteries as generic energy storage elements with particular differences. This work presents a battery model valid for different technologies based on a parametric implementation
ChatGPT vs State-of-the-Art Models: A Benchmarking Study in Keyphrase Generation Task
Transformer-based language models, including ChatGPT, have demonstrated
exceptional performance in various natural language generation tasks. However,
there has been limited research evaluating ChatGPT's keyphrase generation
ability, which involves identifying informative phrases that accurately reflect
a document's content. This study seeks to address this gap by comparing
ChatGPT's keyphrase generation performance with state-of-the-art models, while
also testing its potential as a solution for two significant challenges in the
field: domain adaptation and keyphrase generation from long documents. We
conducted experiments on six publicly available datasets from scientific
articles and news domains, analyzing performance on both short and long
documents. Our results show that ChatGPT outperforms current state-of-the-art
models in all tested datasets and environments, generating high-quality
keyphrases that adapt well to diverse domains and document lengths
Speaker Diarization Based on Intensity Channel Contribution
The time delay of arrival (TDOA) between multiple microphones has been used since 2006 as a source of information (localization) to complement the spectral features for speaker diarization. In this paper, we propose a new localization feature, the intensity channel contribution (ICC) based on the relative energy of the signal arriving at each channel compared to the sum of the energy of all the channels. We have demonstrated that by joining the ICC features and the TDOA features, the robustness of the localization features is improved and that the diarization error rate (DER) of the complete system (using localization and spectral features) has been reduced. By using this new localization feature, we have been able to achieve a 5.2% DER relative improvement in our development data, a 3.6% DER relative improvement in the RT07 evaluation data and a 7.9% DER relative improvement in the last year's RT09 evaluation data
Scientific, Educational, and Environmental Considerations Regarding Mine Sites and Geoheritage: A Perspective from SE Spain
Should abandoned mine sites be eligible for
some official protection under the umbrella of geoconservation?
Providing they have enough educational and
scientific value, the answer is affirmative, and we suggest
that they should be granted protection at the level of
geoheritage sites. Some may see mining as an environmental
disaster, but others, with a more geologically oriented
mind, may perceive mining as a blessing. Mining unveils
the geology, thus allowing a more comprehensive vision of
geological features such as rock units, faults, minerals, etc.
We analyze the advantages and disadvantages of abandoned
mines and districts as geologic observational sites, through
the analysis of two mining districts from SE Spain:
Mazarrón and Cartagena–La Unión. We propose that if an
abandoned mine site or district has enough geological
value, not only the mining site but also the whole geologic
block hosting the ore deposits should also be protected. In
this respect, the Sierra de Cartagena, hosting the Cartagena–
La Unión district, is a valuable geological asset where an
important chapter of the Alpine and late Alpine geologic
history of SE Spain is written
Análisis físico-espacial del mercado Israel Lewites y propuesta de remodelación de terminal de buses
Este Informe Final se creó con el objetivo de cumplir con el requisito para optar del título de Arquitecto. Al mismo tiempo se realiza para ser base a estudios que se realicen sobre dicho tema desarrollado, el cual es: Análisis Físico Espacial del Mercado Israel Lewites con su Terminal de Buses. Esta propuesta de anteproyecto de remodelación como ya antes dicho se emplaza en todo el conjunto de la Terminal de Buses del Mercado Israel Lewites. La finalidad de este trabajo es ofrecer una solución textual y grafica viable para resolver problemáticas encontradas que serán abordadas en el desarrollo de este trabajo, esto incluye, mejorar el nivel de vida y satisfacer las expectativas de los usuarios, comerciantes y trasportistas, por carecer, en la actualidad, de un servicio de terminal de buses adecuado y funcional. En este documento se realiza previamente un planteamiento de la información para comprensión del lector sobre los Mercados Municipales con Terminal de Buses, se plantea desde simples definiciones, clasificación y criterios de diseño hasta llegar a las normativas que rigen el diseño arquitectónico del mismo. Para el Anteproyecto se analizó el contexto urbano del Municipio de Managua respecto a la existencia de Mercados Municipales con Terminal de Buses, mediante esta valoración se conoció la existencia únicamente de 3 Mercados con Terminal de Buses que son: El Mercado Huembés, El Mercado Mayoreo y El Mercado en estudio Mercado Israel Lewites. Posteriormente se realizo un estudio de casos análogos de Mercados Municipales con Terminal de Buses tanto Nacionales como Internacionales, dichas edificaciones se enmarcan en esta tipología y dan un aporte significativo al conocimiento de los espacios arquitectónicos que integran un Mercado Municipal con Terminal de Buses. Este anteproyecto de análisis y diseño considera primordialmente los conceptos de flexibilidad, mejor ambiente de trabajo para transportistas y comerciantes, suficiente iluminación, ventilación natural y una relación directa con las vías para hacer así más fácil el ascenso y descenso de los autobuses. Finalmente se presenta el diseño de Remodelación de la Terminal de Buses del Mercado Israel Lewites el cual es el resultado de todos los aspectos anteriormente señalados, de tal manera que se entienda mediante la propuesta arquitectónica una respuesta a las necesidades de la población, comerciantes y transportistas dando así solución a los diferentes problemas, mejorar el nivel de vida y satisfacer las expectativas de la población
