Els fraseologismes en l'obra dramatica d'Eduard Vidal i Valenciano
Year: 2020

En aquest article s'estudien les unitats fraseologiques en l'obra dramatica d'Eduard Vidal i Valenciano, un dels impulsors del teatre catala contemporani. El caracter costumista i realista d'aquest teatre comporta un treball elaborat sobre el llenguatge, que inclou una rica fraseologia, reflex del llenguatge popular i col*loquial. Seguint el metode filologic i els coneixements de la lexicografia historica, centrem el nostre estudi especialment en les unitats fraseologiques no enregistrades en els diccionaris o que adquireixen en Vidal un sentit diferent al conegut, i, tenint en compte els estudis metodologics sobre la variacio fraseologica i els coneixements de la dialectologia, s'estudien les variacions i les modificacions creatives sobre les unitats fraseologiques, i la manera com s'evidencia la variacio dialectal en aquestes unitats. Our aim in this contribution is to focus attention on the phraseological units of the theatrical work of Eduard Vidal i Valenciano, one of the promoters of contemporary Catalan theater. The realism of this theatrical production involves a detailed work about the language. This work includes a rich phraseology taken from colloquial language. In accordance with the philological and comparative method and with the researches in historical lexicography, we focus on idiomatic expressions that don't appear in dictionaries or that have a special meaning in the theatrical work of Eduard Vidal i Valenciano. Furthermore, taking into account the methodological studies on phraseological variation and the dialectological research, we study the variations on phraseological units.
Simple visualized readout of suppressed coffee ring patterns for rapid and isothermal genetic testing of antibacterial resistance.
Venue: Biosensors bioelectronics
Year: 2020

We present a facile method based on the coffee ring effect that can rapidly detect antibiotic resistant bacteria, as an affordable genetic testing platform. When a colloidal solution of particles is dropped onto a substrate surface, an outward capillary flow upon evaporation induces the migration of the particles to the periphery of the droplet, forming a characteristic ring pattern. Herein, we utilize capture DNA microbeads which in the presence of target nucleic acid, form suppressed ring patterns by hybridization induced crosslinking of the microbeads. The coffee ring based assay is integrated with isothermal amplification based on rolling circle amplification (RCA) to produce long, single stranded target DNA and induce hybridization, via a one step procedure (i CoRi assay) The resultant ring patterns can be simply observed with the naked eye or recorded with a standard mobile device for readout. The i CoRi assay was validated for the rapid and specific detection of the antibiotic resistance gene mecA for MRSA, showing that detection was possible at the sub zeptomolar range ~0.2 zM) with the specificity of distinguishing 2 mismatched bases. The spatial patterns of the microbeads were characterized, showing the dense packing of the microbeads at the center of the droplet and thinning of the ring pattern for the MRSA target, which were distinct from the negative controls MSSA, E. coli, and P. aeruginosa. The images of the microbead patterns were also processed by a simple readout algorithm to discriminate the presence or absence of the coffee ring, to enable diagnostic decision making. The current method provides a rapid and versatile platform for the specific identification of bacterial pathogens and multidrug resistance, especially for diagnosis in resource limited settings.
Multicultural e learning project and comparison of teachers' student teachers' and pupils' perceptions about e learning
Year: 2007

The purpose of this paper is to describe a special multicultural project in e learning that was accompanied by a research. In this project, student teachers experience the planning, implementation and receiving of feedback on computerized teaching of children from diverse multicultural groups. The aim of the research was to examine what e learning is according to teachers, pupils and student teachers from diverse cultural backgrounds. The research population in the sample included 130 respondents in three groups: teachers' student teachers' and pupils'. The uniqueness of this research is the comparison of the three groups and the results that show that in most areas that were checked, significant differences were found between the perception of the teachers, pupils and student teachers. Teachers and student teachers should know what their pupils think of e learning and should consider it in order to improve their performance in e le.
An Evaluation on the Robustness of Five Popular Keypoint Descriptors to Image Modifications Specific to Laser Scanning Microscopy
Venue: IEEE Access
Year: 2018

Laser scanning microscopy (LSM) techniques are of paramount importance at this time for key domains such as biology, medicine, or materials science. Computer vision methods are instrumental for boosting the potential of LSM, providing reliable results for important tasks, such as image segmentation, registration, classification, or retrieval in a fraction of the time that a human expert would require (at similar or even higher accuracy levels) Image keypoint extraction and description represent essential building blocks of modern computer vision approaches, and the development of such techniques has gained massive interest over the past couple of decades. In this paper, we compare side by side five popular keypoint description techniques, scale invariant feature transform (SIFT) speeded up robust features (SURF) binary robust invariant scalable keypoints (BRISK) fast retina keypoint (FREAK) and BLOCK, with respect to their capacity to represent in a reproducible manner image regions contained in LSM data sets acquired under different acquisition conditions. We evaluate this capacity in terms of descriptor matching performance, using data sets acquired in a principled manner and a thorough Precision Recall analysis. We identify which of the five evaluated techniques is most robust to specific LSM image modifications associated to the laser beam power, photomultiplier gain, or pixel dwell, and show that certain pre processing steps have the potential to enhance keypoint matching.
