Highly Efficient Virus-induced Gene Silencing (VIGS) in California Poppy (Eschscholzia californica): An Evaluation of VIGS as a Strategy to Obtain Fu…
2007
†Background and Aims Eschscholzia californica (California poppy) is an emerging model plant for ‘evo‐devo’ studies from the basal eudicot clade of Papaveraceae. California poppy has a relatively small genome, a short life cycle and, most importantly, it is amenable for transformation. However, since this transformation protocol is time consuming, virus-induced gene silencing (VIGS) was evaluated as a fast method to obtain functional data for California poppy genes. †Methods Commercially available California poppy plants were infiltrated with Agrobacterium tumefaciens carrying the tobacco rattle virus plasmids pTRV1 and pTRV2. pTRV2 contained part of the eschscholzia Phytoene Desaturase (EcP…
Current-Based Measurement Technique for High Sensitivity Detection of Resistive Bridges With External Balancing Through Control Voltages
2017
We present a novel approach based on differential measurements of dc currents with very high sensitivity suitable for the detection of very small variations of resistors in Wheatstone full-bridge configurations. External control voltages allow for the compensation of the bridge unbalancing avoiding the need of changing its elements so making the solution suitable for integrated sensor systems. The proposed current-based measurement technique has been implemented through three different circuits, in transimpedance configuration and without the use of any further amplification stage, employing only two active blocks that allow for a very high integration level. The main characteristics of the…
Introduction to Self-Assembled Monolayers
2015
One of the most exciting targets of molecular spintronics field is to go towards multifunctional devices where the properties can be accurately controlled and actively changed. Spin dependent hybridization at the metal/molecule interface could thus be used in the tailoring of the resistive and magnetoresistive response of spintronic devices exploiting chemistry versatility. In this new direction, Self-Assembled Monolayers (SAMs) appear as highly promising candidates since each part and function of this system can be modulated independently (like a molecular LEGO building unit). Despite highly promising, they are still scarcely investigated in the literature probably due to the difficulties …
Cromlechs y círculos de piedras: los datos en el sector central de la cornisa cantábrica
1995
El creciente grado de conocimiento del fenómeno megalítico en Cantabria , ha ido generando un corpus de datos referidos a estructuras que no podían adscribirse a los grupos tipológicos tradicionales: túmulo, dolmen, ó menhir. En este trabajo se revisa esa infonnación, a la luz de los resultados de la reciente excavación en uno de estos monumentos, el círculo de Peña Oviedo. The increasing level of knowledge of the megalithic phenomenon in Cantabria, has been generating a body of data referring to structures that could not be ascribed to traditional typological groups: tumulus, dolmen, or menhir. In this work, this information is reviewed, in light of the results of the recent excavation in …
Superconducting properties of Nb thin films deposited on porous silicon templates
2008
Porous silicon, obtained by electrochemical etching, has been used as a substrate for the growth of nanoperforated Nb thin films. The films, deposited by UHV magnetron sputtering on the porous Si substrates, inherited their structure made of holes of 5 or 10 nm diameter and of 10 to 40 nm spacing, which provide an artificial pinning structure. The superconducting properties were investigated by transport measurements performed in the presence of magnetic field for different film thickness and substrates with different interpore spacing. Perpendicular upper critical fields measurements present peculiar features such as a change in the H_c2(T) curvature and oscillations in the field dependenc…
Der Spur auf der Spur. Sur les traces de la trace
2016
Hinter dem scheinbar einfachen lexikalischen Gewand der »Spur« verbirgt sich eine überraschende Komplexität: Was ist eigentlich eine Spur? Was sind ihre typischen Merkmale? Wodurch unterscheidet sie sich von Abdruck, Zeichen und Indiz? Die Beiträge des vorliegenden Bandes reflektieren den Spurbegriff aus deutsch-französischer sowie aus interdisziplinärer Perspektive. Zu Wort kommen Philosophie, Literatur, Geschichte, Archäologie, Kunstgeschichte, Urbanistik, Kulturwissenschaft und Psychoanalyse.

Age-dependent epileptic encephalopathy associated with an unusual co-occurrence of ZEB2 and SCN1A variants.
2020
Mowat-Wilson syndrome is a genetic disorder associated with a variable phenotype including peculiar facial features associated with intellectual disability, epilepsy, language impairment, and multiple congenital anomalies caused by heterozygous mutation of the ZEB2 gene. The ZEB2 protein is a complex transcription factor that encompasses multiple functional domains that interact with the regulatory regions of target genes including those involved in brain development. Recently, it has been documented that ZEB2 regulates the differentiation of interneuron progenitors migrating from the medial ganglionic eminence to cortical layers by repression of the Nkx2-1 homeobox transcription factor. It…
THE HOMOLOGY OF DIGRAPHS AS A GENERALIZATION OF HOCHSCHILD HOMOLOGY
2010
J. Przytycki has established a connection between the Hochschild homology of an algebra $A$ and the chromatic graph homology of a polygon graph with coefficients in $A$. In general the chromatic graph homology is not defined in the case where the coefficient ring is a non-commutative algebra. In this paper we define a new homology theory for directed graphs which takes coefficients in an arbitrary $A-A$ bimodule, for $A$ possibly non-commutative, which on polygons agrees with Hochschild homology through a range of dimensions.
LE SITE CAMPANIFORME DE LUX LA PERROUZE (SAÔNE-ET-LOIRE)
2014
Le site de Lux La Perrouze (Saône-et-Loire) apporte de nouvelles données sur le Campaniforme bourguignon par la découverte d’une petit ensemble céramique remarquablement homogène, contenu dans le remplissage de quatre structures en creux. Cet ensemble se compose essentiellement de céramique commune, mais quelques gobelets décorés sont également à signaler. L’étude de ce mobilier permet de souligner la remarquable homogénéité des productions du groupe campaniforme bourguignon-jurassien tant pour leur chronologie que pour leurs affinités culturelles. The site of Lux La Perrouze (Saône-et-Loire) has provided new data on the Bell Beaker culture of Burgundy by the discovery of a small and remark…
