Non-homogeneuos conduction of conductive filaments in Ni/HfO2/Si resistive switching structures observed with CAFM

Altres ajuts: ERDF/TEC2011-2792-C02-02Conductive filaments (CFs) in Ni/HfO₂/Si resistive switching structures are analysed at the nanoscale by means of Conductive Atomic Force Microscopy (CAFM). Differences in the CF conductivity are measured depending on the resistive state of the device. Moreover, for both resistance states, non-homogeneous conduction across the CF area is observed, in agreement with a tree-shaped CF

Estrategia en el simulador de negocios Capstone para la empresa Baldwin

Este trabajo representa el trabajo de obtención de grado de los autores de este de la maestría en administración del ITESO a través del estudio de caso del simulador de negocios Capstone. El capítulo uno presenta el marco teórico que recoge información valiosa para la planeación estratégica de una compañía, diferentes tipos de liderazgo, situaciones complejas del mercado como la aparición de una pandemia y ejemplos prácticos mediante el análisis de casos de estudio. Durante el capítulo dos se tiene el primer acercamiento a la industria Capstone y sus características como el detalle del reporte Courier, Balanced Scorecard, reglas, estrategias genéricas y primer vistazo a la situación del mercado. También se utiliza para definir la estrategia de la compañía Baldwin y las acciones concretas a seguir durante la competencia. En los capítulos tres al seis se desarrolla un análisis de los resultados obtenidos por Baldwin en el periodo 2024 a 2031. Cada uno de ellos revisa un periodo de dos años de operaciones y presenta todas las decisiones tomadas por la mesa directiva evaluando efectividad y si deben continuar o no por ese camino mientras revisan a los competidores y las áreas de oportunidad que se pueden aprovechar. En el capítulo siete se encuentran las conclusiones generales de la competencia simulada, las materias de investigación y desarrollo y del posgrado. Cada integrante del equipo Baldwin considera que este documento es evidencia de los conocimientos y aprendizajes adquiridos durante su paso por la maestría de administración de empresas.ITESO, A.C

New high resolution random telegraph noise (RTN) characterization method for resistive RAM

Random Telegraph Noise (RTN) is one of the main reliability problems of resistive switching-based memories. To understand the physics behind RTN, a complete and accurate RTN characterization is required. The standard equipment used to analyse RTN has a typical time resolution of ∼2 ms which prevents evaluating fast phenomena. In this work, a new RTN measurement procedure, which increases the measurement time resolution to 2 μs, is proposed. The experimental set-up, together with the recently proposed Weighted Time Lag (W-LT) method for the analysis of RTN signals, allows obtaining a more detailed and precise information about the RTN phenomenon

Baseline characteristics of patients in the reduction of events with darbepoetin alfa in heart failure trial (RED-HF)

<p>Aims: This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other outcomes.</p> <p>Methods and results: Key demographic, clinical, and laboratory findings, along with baseline treatment, are reported and compared with those of patients in other recent clinical trials in heart failure. Compared with other recent trials, RED-HF enrolled more elderly [mean age 70 (SD 11.4) years], female (41%), and black (9%) patients. RED-HF patients more often had diabetes (46%) and renal impairment (72% had an estimated glomerular filtration rate <60 mL/min/1.73 m2). Patients in RED-HF had heart failure of longer duration [5.3 (5.4) years], worse NYHA class (35% II, 63% III, and 2% IV), and more signs of congestion. Mean EF was 30% (6.8%). RED-HF patients were well treated at randomization, and pharmacological therapy at baseline was broadly similar to that of other recent trials, taking account of study-specific inclusion/exclusion criteria. Median (interquartile range) haemoglobin at baseline was 112 (106–117) g/L.</p> <p>Conclusion: The anaemic patients enrolled in RED-HF were older, moderately to markedly symptomatic, and had extensive co-morbidity.</p&gt

Dedicated random telegraph noise characterization of Ni/HfO2-based RRAM devices

In this work, random telegraph noise (RTN) associated to discrete current fluctuations in the high resistive state of Ni/HfO2-based RRAM devices is investigated. For this purpose, a dedicated software tool has been developed to control the instrumentation and to perform successive and smart RTN measurements in the time domain. After data acquisition, the advanced Weighted Time Lag (WTL) method is employed to accurately identify the contribution of multiple electrically active defects in multilevel RTN signals. Finally, the internal dynamics of trapping and de-trapping processes through the defects close to the filamentary path and its dependence on voltage and time are analyzed
