Monolithically integrated 112 Gbps PAM4 optical transmitter and receiver in a 45†nm CMOS-silicon photonics process.

We demonstrate a transmitter and receiver in a silicon photonics platform for O-band optical communication that monolithically incorporates a modulator driver, traveling-wave Mach-Zehnder modulator, control circuitry, photodetector, and transimpedance amplifier (TIA) in the GlobalFoundries Fotonix (45SPCLO) platform. The transmitter and receiver show an open 112 Gbps PAM4 eye at a 4.3 pJ/bit energy efficiency, not including the laser. Extensive use of gain-peaking enables our modulator driver and TIA to achieve the high bandwidths needed in the 45 nm CMOS-silicon photonics process. Our results suggest an alternative to the frequent approach of bump-bonding BiCMOS drivers and TIAs to silicon photonics.

Experiencias latinoamericanas en la prevención de la suicidalidad en jóvenes y adolescentes: una revisión teórica / Latin American experiences in the prevention of suicidality in young people and adolescents: a theoretical review

Resumen Introducción: A nivel latinoamericano el suicidio en jóvenes y adolescente representa una problemática grave, por lo que es necesario trabajar en su prevención. En ese sentido, este trabajo presenta una revisión teórica narrativa sobre la temática. Objetivo: Conocer las principales experiencias de prevención de la suicidalidad en jóvenes y adolescentes de Latinoamérica en los últimos 15 años. Método: Se revisaron y analizaron 44 estudios empíricos, realizando búsquedas bibliográficas en revistas científicas indexadas en Scopus, Scielo, WoS, REDALYC y ERIH PLUS y motores de búsqueda como Google Académico y EBSCO. Resultados: Los hallazgos obtenidos en los 44 estudios se organizaron en tres categorías: 1) diagnósticos sobre suicidalidad realizados en población juvenil y adolescente; 2) intervenciones psicoterapéuticas destinadas a tratamiento en suicidalidad; y 3) intervenciones en base a programas, estrategias y técnicas enfocadas en la prevención del suicidio juvenil y adolescente. Discusión: Los principales diagnósticos asociados a la suicidalidad están vinculados a disfuncionalidades emocionales, donde las mujeres son las principales afectadas, la familia y el entorno surgen como principales factores protectores o de riesgo dependiendo de su funcionalidad y cohesión. Además, las intervenciones más valoradas están asociadas a los modelos clásicos de psicoterapia y las estrategias psicoeducativas aparecen como los principales focos de los programas preventivos. Conclusión: Por la multifactoriedad del fenómeno, se debería realizar un cambio paradigmal en el enfrentamiento de la suicidalidad.

Abstract Introduction: At the Latin American level, suicide in young people and adolescents represents a serious problem, so it is necessary to work on its prevention. In this sense, this work presents a narrative theoretical review on the subject. Objective: To know the main experiences of suicide prevention in young people and adolescents in Latin America in the last 15 years. Method: 44 empirical studies were reviewed and analyzed, performing bibliographic searches in scientific journals indexed in Scopus, Scielo, WoS, REDALYC and ERIH PLUS and search engines such as Google Scholar and EBSCO. Results: The findings obtained in the 44 studies were organized into three categories: 1) diagnoses of suicidality made in the youth and adolescent population; 2) psychotherapeutic interventions aimed at treating suicidality; and 3) interventions based on programs, strategies and techniques focused on the prevention of youth and adolescent suicide. Discussion: The main diagnoses associated with suicidality are linked to emotional dysfunctionalities, where women are the main affected, the family and the environment appear as the main protective or risk factors depending on their functionality and cohesion. In addition, the most valued interventions are associated with the classic models of psychotherapy and psychoeducational strategies appear as the main focuses of preventive programs. Conclusion: Due to the multifactorial nature of the phenomenon, a paradigm shift should be made in the confrontation of suicidality.

Designing Shift Handoff Software: Clinical Learners and Design Students Collaborate Using the "Design Thinking" Process.

Handoffs in patient care responsibilities between practitioners are common in the hospital setting. Because inadequate communication can lead to patient harm, professional organizations have published recommendations and practical guides to support standardized workflow. However, currently available electronic medical record (EMR) tools rarely provide the requisite functionality to support work and often suffer from major usability flaws. Our internal medicine residency program sponsored a quality improvement initiative to improve the design of handoff tools. To support this initiative, our medical informatics program collaborated with a school of architecture and design to identify requirements and ideate interface prototypes. In this article, we describe how we used Design Thinking principles and methods to inform our product design lifecycle, create novel designs, and teach inter-professional students health systems science concepts.
