Why does the APA recommend the use of serif fonts?
2013
Antecedentes: las normas de publicación de la American Psychological Association recomiendan el uso de un tipo de letra con serif en los manuscritos (Times New Roman). Sin embargo, no parece haber ninguna razón bien sustentada por la que las fuentes con serif produzcan ventaja alguna durante la lectura de palabras. Método: para examinar el papel de los serifs se realizó un experimento en el que se presentaron frases bien con una fuente serif o sansserif de la misma familia, mientras se registraban los movimientos oculares de los participantes. Resultados: los resultados no revelaron diferencias debidas al tipo de letra en los movimientos oculares, a excepción de un efecto mínimo en el númer…
Mitochondrial DNA deletion and male infertility
2009
Abstract The term “male infertility” does not constitute a defined clinical syndrome, but rather, a collection of different conditions exhibiting a variety of aetiologies and varying diagnosis. In men, oligozoospermia, asthenozoospermia, teratozoospermia and azoospermia are the main causes of infertility. The present research is aimed to investigate if mtDNA deletions can cause sperm defects in idiopathic astenozoospermic patients with different sperm motility and sperm concentration. The incidence of deletions in mtDNA (mtDNA) was co-related with diagnostic categorization of male infertility when 6.6kb out of the 16.6kb of the mitochondrial genome was amplified from whole sperm samples, f…

Highly-parallelized simulation of a pixelated LArTPC on a GPU
2023
The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The alg…
Prime indicazioni sulle biocenosi associate alle mummie delle Catacombe dei Cappuccini di Palermo
2009
La fama del convento, costruito dai Cappuccini di Palermo nel 1533, è dovuta in gran parte alle famose "Catacombe". L’origine delle catacombe si fa risalire al 1599 circa, quando i frati, sfruttando una preesistente cavità naturale al di sotto dell’altare maggiore della chiesa, trasferirono le salme di 40 frati precedentemente sepolti presso il lato meridionale della chiesa stessa. I frati iniziarono ad ampliare le catacombe, scavando nel sottosuolo, in relazione al crescente numero di nuove salme che nel tempo si conservavano. Allo stato attuale le catacombe sono una sorta di cimitero sotterraneo, in uso nel XVII secolo, costituito da lunghe gallerie scavate nel tufo per un’estensione di c…
Multiplex Ligation-dependent Probe Amplification (MLPA)
2011
The Multiplex Ligation-dependent Probe Amplification (MLPA) is a PCR-based method. The procedure relies on sequence-specific probe hybridization of genomic DNA, followed by multiplex-PCR amplification of the hybridized probe and a semiquantitative analysis of the resulting PCR products. MLPA allows the analysis of around 40 loci in the same reaction, and is a sensitive and relatively fast technique. Only a small amount of DNA is required and results are available within 2 days.The critical factors when performing MLPA analyses from formalin-fixed paraffin-embedded (FFPE) tissues are DNA integrity and purity; for this reason, a suitable DNA extraction method must be chosen.The MLPA protocol …
On application of kernel PCA for generating stimulus features for fMRI during continuous music listening
2018
Background There has been growing interest towards naturalistic neuroimaging experiments, which deepen our understanding of how human brain processes and integrates incoming streams of multifaceted sensory information, as commonly occurs in real world. Music is a good example of such complex continuous phenomenon. In a few recent fMRI studies examining neural correlates of music in continuous listening settings, multiple perceptual attributes of music stimulus were represented by a set of high-level features, produced as the linear combination of the acoustic descriptors computationally extracted from the stimulus audio. New method fMRI data from naturalistic music listening experiment were…
