THE ROLE OF NON-GAUSSIAN SOURCES IN THE TRANSIENT DYNAMICS OF LONG JOSEPHSON JUNCTIONS

2013

We analyze the effects of different non-Gaussian noise sources on the transient dynamics of an overdamped long Josephson junction. We find nonmonotonic behavior of the mean escape time as a function of the noise intensity and frequency of the external driving signal for all the noise sources investigated.

Barriers to the use of mobile sales force automation systems: a salesperson’s perspective

2015

Purpose – The purpose of this paper is to examine the barriers associated with the adoption and use of mobile sales force automation (SFA) systems from a salesperson’s perspective. Design/methodology/approach – A qualitative investigation of two business-to-business companies was conducted. Data collected from ten semi-structured interviews with directors or sales managers were analyzed to understand the main barriers to SFA system adoption. Findings – The study confirms the existence of three barriers (customer knowledge, quality of information and the characteristics of mobile devices) to a mobile SFA system use and identifies two additional barriers: lack of time and optimization issues…

Characterization of PP-cLT Waveguides for Second-Harmonic-Generation and Wavelength-Conversion in the C + L Band of Optical Communications

2010

We report the characterization of single-mode optical waveguides at telecom wavelength, realized in congruent lithium-tantalate. We demonstrate that waveguides realized by proton-exchange show a nonlinear coefficient matching that expected in a bulk crystal.

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

Locus of Control and Mothers' Return to Employment

2016

This paper investigates the effect of locus of control (LOC) on the length of mothers’ employment break after childbirth. Using data from the German Socio-Economic Panel Study (SOEP), duration data reveals that women with an internal LOC return to employment more quickly than women with an external LOC. We find evidence that this effect is mainly related to differential appreciation of the career costs of longer maternity leave. Given the high level of job protection enjoyed by mothers in Germany, economic consequences of differences in this non-cognitive skill can be expected to be larger in other settings.

Infraglottic airway devices and techniques.

2005

Airway management involves far more than just proficiency with tracheal intubation techniques. There are several infraglottic techniques available and the method chosen will depend on the accessibility of equipment, the level of training and expertise, and the patient's specific injury or disease. Endotracheal intubation is most commonly performed by direct laryngoscopy. Several modifications of laryngoscope blades and a variety of adjuncts such as bougies may help to accomplish even a difficult airway. Rigid intubation fibrescopes do improve the view of the larynx, especially in patients with difficult anatomy. They also permit tracheal intubation with less head and cervical spine movement…

Die fiberoptische Intubation neurochirurgischer Patienten*

1993

Patients with cervical spine injury presenting with respiratory distress require airway management that does not compromise integrity of the atlanto-occipital joint. Endotracheal intubation by means of direct laryngoscopy is not suitable. The method of choice is nasotracheal intubation of the awake patient, using a flexible fibre bronchoscope. If anatomy or surgical access render the nasal approach impossible, fibre optic intubation can be performed orotracheally, utilising specific technical aids. Flexible fibrescopes are available in different sizes (length and diameter): selection is base on the patient's anatomical requirements. Aids to orotracheal intubation are constructed with a bore…

Resistive switching behaviour in ZnO and VO 2 memristors grown by pulsed laser deposition

2014

The resistive switching behaviour observed in microscale memristors based on laser ablated ZnO and VO 2 is reported. A comparison between the two materials is reported against an active device size. The results show that devices up to 300 × 300 μm 2 exhibit a memristive behaviour regardless of the device size, and 100 × 100 μm 2 ZnO-based memristors have the best resistance off/on ratio.

Prevalencia e influencia de la violencia homofóbica sobre la sintomatología depresiva y el nivel de autoestima

2020

Las personas homosexuales y bisexuales constituyen un colectivo sobre el que se ejerce violencia. Este estudio analiza la prevalencia e influencia que ejerce la violencia homofóbica sufrida a lo largo de la vida sobre la sintomatología depresiva y el nivel de autoestima. La muestra está compuesta por 730 personas homosexuales o bisexuales con edades comprendidas entre los 18 y los 60 años (M = 28.47; DT = 8.81). Los resultados indican que entre el 29.6% y 76.7% ha recibido violencia psicológica o verbal y entre el 4.2% y el 19.6% ha sufrido violencia física a lo largo de su vida. También se obtienen diferencias significativas según el género, siendo los hombres quienes refieren mayores tasa…
