Redescription of Hemileius suramericanus (Acari, Oribatida, Scheloribatidae) with comments about Neotropical congeneric species

This paper represents the first redescription of Hemileius suramericanus (Hammer, 1958) (Oribatida, Scheloribatidae). Morphological and chaetotactic details are added to original Hammer's description. The species is compared with others Neotropical species of Hemileius and two new synonyms, H. laticlava and H. confundatus sensu Hammer, are proposed.Fil: Fredes, Natalia.

Index for asset value measure obtained from condition monitoring digitalized data interpretation. A railway asset management application

Hosted by the Johannes Kepler University, Linz, Austria. May 23-24, 2019The objective of any asset is to provide value to the organization, being the corner stone to get a highest possible economic benefit in a sustainable way. An effective asset value management demands method that allow measuring and comparing the expected value with the real value realized at any time during its life cycle for value informed decision-making. Digitalization is providing new data about events and states related to asset condition and risk, information that can be reinterpreted to generate value measure strategies. This paper presents a proposal of TVO (Total Value of Ownership) model where it is possible to quantify and measure the value, including its monitoring throughout the life cycle of the asset and/or system. Proposed TVO model is focused on Safety, one of the most relevant value factors for Industry and Infrastructure sectors. Asset events and states are intrinsically linked to the defined failure modes. Consequently, it is necessary to structure the system information around the failure modes that have been defined, in order to obtain a value measurement index. A railway use case is presented

Steady State Detection of Chemical Reaction Networks Using a Simplified Analytical Method

Chemical reaction networks (CRNs) are susceptible to mathematical modelling. The dynamic behavior of CRNs can be investigated by solving the polynomial equations derived from its structure. However, simple CRN give rise to non-linear polynomials that are difficult to resolve. Here we propose a procedure to locate the steady states of CRNs from a formula derived through algebraic geometry methods. We have applied this procedure to define the steady states of a classic CRN that exhibits instability, and to a model of programmed cell death

Code Detection for Hardware Acceleration Using Large Language Models

Large language models (LLMs) have been massively applied to many tasks, often surpassing state-of-the-art approaches. While their effectiveness in code generation has been extensively studied (e.g., AlphaCode), their potential for code detection remains unexplored. This work presents the first analysis of code detection using LLMs. Our study examines essential kernels, including matrix multiplication, convolution, and fast-fourier transform, implemented in C/C++. We propose both a preliminary, naive prompt and a novel prompting strategy for code detection. Results reveal that conventional prompting achieves great precision but poor accuracy (68.8%, 22.3%, and 79.2% for GEMM, convolution, and FFT, respectively) due to a high number of false positives. Our novel prompting strategy substantially reduces false positives, resulting in excellent overall accuracy (91.1%, 97.9%, and 99.7%, respectively). These results pose a considerable challenge to existing state-of-the-art code detection methods

Erroneous measurement of haemodynamic parameters by PiCCO™ monitor in a critically ill patient with renal replacement therapy: a case report

The PiCCO™ monitor (Pulsion Medical System, Melsungen, Hessen, Germany) has become an alternative method of haemodynamic invasive monitoring for the critically ill patient. The determination of the continuous cardiac output by arterial pulse contour analysis requires the periodic calibration of the monitor. This calibration is performed by the injection of a bolus of 15-20 ml cold saline through a central line catheter [1-3]. We present the case of a 54-year-old woman with breast cancer who underwent cord decompression surgery for bone metastasis. On the seventh postoperative day she developed multiorgan system failure (septic shock + respiratory insufficiency + acute renal failure + disseminated intra-vascular coagulopathy) due to nosocomial pneumonia. The patient was admitted to the intensive care unit and the PiCCO™ monitor was used for invasive haemodynamic monitoring. A Certofix™ Trio HF catheter (Braun, Munich, Bayern, Germany) was placed uneventfully in the right internal jugular vein to carry out continuous venous-venous haemodialysis (CVVH-D). The Certofix™ Trio HF is a triple-lumen catheter made of polyurethane with three lumens (first channel, distal = 16 G; second channel, middle = 12 G; and third channel, proximal = 12 G). The distal lumen was used for the calibrations of the PiCCO™ monitor due to the high-risk of insertion of another central line in a patient with severe coagulopathy. The analysis of the area under the thermo-dilution curve showed a hypodynamic state that was treated following the PiCCO™ monitor algorith

Investment in R&D and its link with income: theory and inquiry about the behaviour of the European economies

Vivimos en un tiempo caracterizado por una profunda transformación tecnológica dentro de economías que operan a escala global. En este contexto, la innovación aparece como un factor clave para la mejora de las condiciones productivas de un sistema económico, que en el caso europeo, es fundamental para mejorar la competitividad de las economías de la zona. Este trabajo indaga sobre la vinculación entre gasto en innovación y nivel de renta en quince países europeos, estudiándose la existencia de grupos de naciones que presentan pautas similares de gasto en I+D+i. Para ello, se han utilizado tanto el análisis de correlaciones como el quick cluster.______________________________________________We are living a time in which the economies are operating on a global scale and are affected by an intense technological change. In this context, innovation emerges as a key factor to enhance the productivity in the economic systems. This variable becomes fundamental for increasing the competitiveness of European economies. This paper inquires into the link between investment in innovation and income level in 15 European countries, not only studying each of them, but also trying to find groups with similar spending patterns of behaviour. It has been taken into account variables such as the level and composition of R&D outlays, the proportion of this investment into the GDP and how much of it is spent by Public Sector. Correlation analysis and quick cluster have been the statistical tools used to undertake this task

Circunstancias predisponentes en el consumo de drogas en adolescentes de los barrios Román Esteban y José Antonio Salazar, municipio de Jinotepe, Carazo, II Semestre del 2003.

La violencia intrafamiliar que viven los adolescentes es aumido por los jóvenes como un factor de riesgo predisponente para el consumo de drogas. Como alternativa de solución se presenta la estrategia de prevención entendida como el evitar que usen drogas, mediante la resistencia a la oferta para reducir o atenuar la demanda
