Sub-mA current measurement by means of GMR sensors and state of the art lock-in amplifiers
2015
Electric current measurement at the range of μA in integrated circuit has been traditionally carried out by micro-electronically engineered systems, such as current mirrors or charging capacitors. However, off-line, i.e., non-intrusive methods provide advantages related to size and power consumption. In this sense, giant magnetoresistance (GMR) magnetic sensors are optimal due to their sensitivity and CMOS compatibility. In this work, we make use of specifically designed CMOS GMR-based current sensors in combination with a custom electronic interface based on a low-voltage low-power lock-in amplifier, demonstrating the capability of this combination for current measurement in the range of μ…
Epigenetic biomarkers: A new perspective in laboratory diagnostics.
2012
Epigenetics comprises the study of chemical modifications in the DNA and histones that regulates the gene expression or cellular phenotype. However, during the last decade this term has evolved after the elucidation of different mechanisms (microRNAs and nuclear organization of the chromosomes) involved in regulating gene expression. Epigenetics and the new designed technologies capable to analyze epigenetic changes (e.g., methylated DNA, miRNAs expression, post-translational modifications on histones among others) have disclosed an appealing scenario that will offer for the biomedical sciences new biomarkers for the study of neurodegenerative diseases, multifactorial complex diseases, rare…
Compact 20-pass thin-disk amplifier insensitive to thermal lensing
2019
We present a multi-pass amplifier which passively compensates for distortions of the spherical phase front occurring in the active medium. The design is based on the Fourier transform propagation which makes the output beam parameters insensitive to variation of thermal lens effects in the active medium. The realized system allows for 20 reflections on the active medium and delivers a small signal gain of 30 with M$^2$ = 1.16. Its novel geometry combining Fourier transform propagations with 4f-imaging stages as well as a compact array of adjustable mirrors allows for a layout with a footprint of 400 mm x 1000 mm.

Presentación del Monográfico: una mirada a la emigración española cualificada reciente: Estado de la cuestión y enfoques teóricos
2018
The study of qualified emigration has returned to the political and scientific agendas in recent decades. Currently the theoretical approaches have changed from a completely renewed economic, political, social and technological context. This article presents a summary of these new approaches and a current overview of skilled migration of Spaniards, based on a review of the specialized literature.
Multiple response optimization of blueberry juice depectinization
2017
ABSTRACT: To obtain blueberry juice with a high content of antioxidants it is necessary to introduce an enzymatic depectinization step into the process. Due to the importance of this step in the final properties of blueberry juice it is critical that the operation conditions be optimized. The aim of this research was to evaluate the effects of temperature, duration of treatment and enzymatic complex concentration on anthocyanin content and juice yield during enzymatic depectinization. Results indicated that the best factor combination was 50ºC during 1.3h and 4mg 100g-1 of LAFASE(r) CLARIFICATION and 8mg 100g-1 of LAFASE(r) HE GRAND CRU enzymatic complex concentration. Under these condition…
Aging Successfully: The Role of Genetics and Environment in the Era of the Aging-Boom. Potential Therapeutic Implications
2019
Aging is one of the main health-related challenges in the world. The average life expectancy of the global population at birth is increasing up to 72 years, in 2016 and it increases about two years every decade. The healthcare costs in many countries are very high because of the increased number of unhealthy populations, and the consequent increase of severe age-related disabilities [1]. Therefore, the goal of the future should be the achievement of the so-called “health-span” (healthy-life-span), more than the treatment of age-related disease to prevent the collapse of the health system. In order to achieve this objective, it is necessary to identify new targets and biomarkers and to addre…

Prefazione al volume "Mirdita në Arkivin e Propagandës Fide në shekujt XVII-XIX" contenente una raccolta di documenti storici - trascritti e tradotti in albanese da Arben Ndreca - sulla regione di Mirdita nell'Albania settentrionale, i cui originali sono conservati presso l'Archivio Storico di Propaganda Fide in Vaticano. Si tratta principalmente di relazioni che i prelati della Chiesa Cattolica in Albania inviavano periodicamente alla Congregazione di Propaganda Fide durante un periodo di oltre tre secoli (prima metà XVII sec. - fine XIX sec.) e che oggi costituiscono una preziosa fonte di dati per la storia di quella regione.
