UAS - ATM Simulated Integrated Scenario Technical Debriefer

An unmanned aerial system is an aircraft that flies with no crew onboard. These vehicles and manned aircraft are provided with a black box that records all flight variables (altitude, speed, acceleration, etc...) and cockpit conversations. One of its functions is to store data in the event of an accident, to analyze what happened instants prior the incident. This data is stored in order to be treated afterwards. ICARUS research group is working on an unmanned aerial system simulator called ISIS, used to evaluate the integration of the unmanned aerial systems into non-segregated airspace. This simulator, like an aircraft, has a black box that generates and stores flight data for later analysis. The particularities of the unmanned aerial system simulator require specific software to analyze the data in depth. This project aims to design and implementation of software to analyze data files generated by this simulator. The system must be able to represent charts using any magnitude in function of time. It must also have tools to detect air traffic conflicts with other commercial aircraft and analyze parameters of the different flight plan sections. The application allows exporting these charts to vector format and performing unit conversions. In addition, the software has been extended to analyze any type of data file from any platform. Thus, the software is not specific to the ISIS simulator, but is able to process any type of data file. To check the operation of this extension, it has been tested with data from three different platforms: flight data from a real unmanned helicopter, from an unmanned aircraft simulator and from unmanned flights performed by NASA.Un s istema aéreo no tripulado e s una aeronave que vuela sin personal a bordo. Tanto estos vehículos como los aviones tripulados están provistos de una caja negra que registra la totalidad de l a s variables de vuelo (altitud, velocidad, aceleración , etc ... ) y las conversaciones de cabina . Una de sus funciones es almacenar datos que, en caso de un accidente, permita analizar lo ocurrido en los momentos previos a este. Estos datos son almacenados con el objetivo de ser tratados a posteriori . El grupo de investigación ICARUS está trabajando en un simulador de aviones no tripulados llamado ISIS, con el que se pretende evaluar la integración de éstos en el espacio aéreo no segregado. Este simulador, al igual que una aeronave, contiene una caja negra que genera y almacena los datos de vuelo para su posterior análisis. L as particularidades del simul ador de aviones no tripulados hacen que, para poder analizar los datos en profundidad, sea necesario un software específico. Este proyecto tiene como objetivo el diseño e implementación de un software para el análisis de ficheros de datos generados por es te simulador. El sistema debe ser capaz de representar mediante gráficos cualquier magnitud que éste genere en función del tiempo. Además debe tener herramientas para detectar conflictos de tráfico aéreo con otros aviones comerciales y a nalizar parámetros de las distintas fases del plan de vuelo. La aplicación ha de permitir exportar sus graficas a formato vectorial y realizar conversiones de unidades. Además , el software, ha sido extendido para analizar cualquier tipo de fichero de datos . De este modo a pa rte dar las herramientas necesarias para analizar los datos propios del simulador, ofrece flexibilidad para poder analizar ficheros de otras plataformas. Para comprobar el funcionamiento de dicha extensión se han realizado pruebas con datos de tres plataf ormas diferentes: datos de vuelo de un helicóptero real no tripulado, del simulador de aviones no tripulados y de vuelos realizados por un avión no tripulado de NASA

Single-frame super-resolution in remote sensing: a practical overview

Image acquisition technology is improving very fast from a performance point of view. However, there are physical restrictions that can only be solved using software processing strategies. This is particularly true in the case of super resolution (SR) methodologies. SR techniques have found a fertile application field in airborne and space optical acquisition platforms. Single-frame SR methods may be advantageous for some remote-sensing platforms and acquisition time conditions. The contributions of this article are basically two: (1) to present an overview of single-frame SR methods, making a comparative analysis of their performance in different and challenging remote-sensing scenarios, and (2) to propose a new single-frame SR taxonomy, and a common validation strategy. Finally, we should emphasize that, on the one hand, this is the first time, to the best of our knowledge, that such a review and analysis of single SR methods is made in the framework of remote sensing, and, on the other hand, that the new single-frame SR taxonomy is aimed at shedding some light when classifying some types of single-frame SR methods.This work was supported by the Spanish Ministry of Economy under the project ESP2013 - 48458-C4-3-P, by Generalitat Valenciana through project PROMETEO-II/2014/062, and by Universitat Jaume I through project P11B2014-09

Latent topic-based super-resolution for remote sensing

This letter presents a novel single-image Super-Resolution (SR) approach based on latent topics specially designed to remote sensing imagery. The proposed approach pursues to super-resolve topics uncovered from low-resolution images instead of super-resolving image patches themselves. An experimental comparison is con- ducted using nine di ff erent SR methods over four aerial image data- sets. Experiments revealed the potential of latent topics in remote sensing SR by reporting that the proposed approach is able to provide a competitive advantage especially in low noise conditions.This work was supported by the Spanish Ministry of Economy under the projects ESP2013-48458- C4-3-P and ESP2016-79503-C2-2-P, by Generalitat Valenciana through project PROMETEO-II/2014/ 062, and by Universitat Jaume I through project P11B2014-09

MARQ: an online tool to mine GEO for experiments with similar or opposite gene expression signatures

The enormous amount of data available in public gene expression repositories such as Gene Expression Omnibus (GEO) offers an inestimable resource to explore gene expression programs across several organisms and conditions. This information can be used to discover experiments that induce similar or opposite gene expression patterns to a given query, which in turn may lead to the discovery of new relationships among diseases, drugs or pathways, as well as the generation of new hypotheses. In this work, we present MARQ, a web-based application that allows researchers to compare a query set of genes, e.g. a set of over- and under-expressed genes, against a signature database built from GEO datasets for different organisms and platforms. MARQ offers an easy-to-use and integrated environment to mine GEO, in order to identify conditions that induce similar or opposite gene expression patterns to a given experimental condition. MARQ also includes additional functionalities for the exploration of the results, including a meta-analysis pipeline to find genes that are differentially expressed across different experiments. The application is freely available at http://marq.dacya.ucm.es

Comparative Analysis of 5-Year Clinical Outcomes and Patterns of Failure of Proton Beam Therapy Versus Intensity Modulated Radiation therapy for Prostate Cancer in the Postoperative Setting

Purpose: Although proton beam therapy (PBT) is a rapidly expanding modality to treat prostate cancer compared with intensity modulated radiation therapy (IMRT), data comparing disease control outcomes and patterns of failure in the postprostatectomy setting remain substantially limited. Methods and Materials: All patients who underwent postoperative IMRT or PBT to the prostate bed only at a single institution were included (2009-2017). Endpoints included biochemical failure (BF; using institutional and recent cooperative group trial definitions), local failure (LF), regional failure (RF), distant failure (DF), and all-cause mortality. A case-matched cohort analysis was performed using 3-to-1 nearest-neighbor matching; multivariable Cox proportional hazards modeling (MVA) estimated hazard ratios for disease-related outcomes by treatment modality. Results: Of 295 men, 260 were matched (n = 65 PBT, 195 IMRT); after matching, only age at diagnosis (P .05). RT modality was not significantly associated with BF on MVA using institutional or cooperative group definitions (all P > .05), nor with LF (P = .82), RF (P = .11), DF (P = .36), or all-cause mortality (P = .69). Patterns of failure were qualitatively similar between cohorts (DF: bone, retroperitoneal nodes, lung). Conclusions: In this single institution, case-matched analysis, PBT yielded similar long-term disease-related outcomes and patterns of failure to IMRT in the postprostatectomy setting.

Incidence of Long-Term Esophageal Dilation With Various Treatment Approaches in the Older Head and Neck Cancer Population

Purpose: Treatments for locoregionally advanced head and neck cancer (LAHNC) negatively impact swallowing function, but the long-term incidence of severe toxicity requiring esophageal dilation is not well-documented in the population. The aim of this study was to compare the incidence of long-term esophageal dilation across varying treatments for LAHNC.Methods and Materials: We identified 5,223 patients with LAHNC diagnosed from 2000 to 2009 in the SEER-Medicare database. We compared the incidence of esophageal dilation for surgery alone vs. surgery plus adjuvant radiotherapy (RT) and chemoradiotherapy (CRT) vs. definitive RT or CRT.Results: The cumulative incidence of esophageal dilation for all sites at 10 years, according to treatment group were as follows: CRT, 14% (95% confidence interval (CI), 12–17%); definitive RT, 13% (95% CI, 10–16%); surgery alone, 5% (95% CI, 3–7%); surgery and CRT, 15% (95% CI, 11–19%); surgery and adjuvant RT: 10% (95% CI, 8–13%). There was no significant difference in the incidence of esophageal dilation between surgery plus adjuvant RT/CRT or definitive RT/CRT (p = 0.37), but the incidence was significantly increased in both groups compared to surgery alone (p = 0.003). On multivariable analysis, chemotherapy was associated with significantly increased incidence of esophageal dilation (HR 2.9, 95% CI 1.5–5.5, p < 0.001) in oropharyngeal cancers.Conclusions: The incidence of esophageal dilation is similar in LAHNC patients undergoing RT with or without surgery. Chemoradiotherapy increases the long-term risk of esophageal dilation events over surgery alone

Bennett Public School Principal Induction Program

Thesis advisor: Irwin BlumerEnsuring equity in education and academic success for all students requires a highly skilled principal engages others in continually improving the instructional program in order to meet the needs of students. Over the past few years, a number of reports have indicated that the role of principal is becoming more challenging. School districts are having trouble attracting and retaining highly qualified principals, and principal candidates and current principals are not prepared or supported enough for managing the various demands of the job. In 2010, according to the district, 49 of the 129 active principals had been in their role for three years or fewer. The Bennett Public Schools are designing a leadership development program for aspiring and new principals. This study is designed to support the Bennett Public Schools in its efforts to develop effective school leaders and is focused on answering two research questions: What does the literature say about skills that are required to be an effective urban principal? Based on the literature review and interviews with principals in Bennett Public Schools, what should be the components of an induction program to support principals in their first three years in the district? Twelve novice Bennett Public Schools principals were interviewed using a semi-structured interview protocol. The pool of interviewees reflects the diversity of the population in characteristics including gender, racial diversity, elementary and secondary schools, as well as the various structures of schools in the district: traditional, pilot, innovation and in-district charter. A synthesis of literature and interviews reinforces the importance of the Bennett Public Schools establishing an induction program with a clear set of competencies, or a competency framework, aligned with the 2011 standards for effective school leadership from the Massachusetts Department of Elementary and Secondary Education. This program should include five components: recruitment and selection strategy, year-long site-based internship, mentoring and coaching, relevant professional development and evaluation of the program and participants.Thesis (EdD) — Boston College, 2012.Submitted to: Boston College.

Risk factors for one-year mortality in hospitalized adults with severe covid-19 comment

As the body''s immunity declines with age, elderly-hospitalized patients due to COVID-19 might be at higher mortality risk. Therefore, the aim of this prospective study was to examine the possible risk factors (demographic, social or comorbidities) most associated with mortality one-year after diagnosis of COVID-19. Routine data were collected from a cohort of hospitalized adults with severe COVID-19. The primary endpoint was mortality at one-year after diagnosis of COVID-19. We used a Cox proportional hazard model to estimate the hazard ratios (HRs) for both all-cause and specific cardiorespiratory mortality. A fully adjusted model included sex, socioeconomic status, institutionalization status, disability, smoking habit, and comorbidities as confounders. A total of 368 severe cases hospitalized on average 67.3 +/- 15.9 years old were included. Participants aged >= 71 years had significantly higher HRs for all-cause mortality (adjusted HRs = 2.86, 95%CI: 2.01-4.07) and cardiorespiratory mortality (adjusted HRs = 2.86, 95%CI: 1.99-4.12). The association between age and mortality after diagnosis of COVID-19 due to both all-causes and cardiorespiratory mortality showed a consistent dose-response fashion. Institutionalization, disability, and socioeconomic status also showed a significant association with mortality. In conclusion, aging itself was the most important risk factor associated with mortality one year after diagnosis of COVID-19. People with disabilities, institutionalized or low socioeconomic status are significantly more likely to die after COVID-19

GHOST Commissioning Science Results II: a very metal-poor star witnessing the early Galactic assembly

This study focuses on Pristine$\_180956.78$$-$$294759.8$ (hereafter P180956, [Fe/H] $=-1.95\pm0.02$), a star selected from the Pristine Inner Galaxy Survey (PIGS), and followed-up with the recently commissioned Gemini High-resolution Optical SpecTrograph (GHOST) at the Gemini South telescope. The GHOST spectrograph's high efficiency in the blue spectral region ($3700-4800$~\AA) enables the detection of elemental tracers of early supernovae (e.g. Al, Mn, Sr, Eu), which were not accessible in the previous analysis of P180956. The star exhibits chemical signatures resembling those found in ultra-faint dwarf systems, characterised by very low abundances of neutron-capture elements (Sr, Ba, Eu), which are uncommon among stars of comparable metallicity in the Milky Way. Our analysis suggests that P180956 bears the chemical imprints of a small number (2 or 4) of low-mass hypernovae (\sim10-15\msun), which are needed to reproduce the abundance pattern of the light-elements (e.g. [Si, Ti/Mg, Ca] $\sim0.6$), and one fast-rotating intermediate-mass supernova (\sim300\kms, \sim80-120\msun). Both types of supernovae explain the high [Sr/Ba] of P180956 ($\sim1.2$). The small pericentric (\sim0.7\kpc) and apocentric (\sim13\kpc) distances and its orbit confined to the plane (\lesssim 2\kpc), indicate that this star was likely accreted during the early Galactic assembly phase. Its chemo-dynamical properties suggest that P180956 formed in a system similar to an ultra-faint dwarf galaxy accreted either alone, as one of the low-mass building blocks of the proto-Galaxy, or as a satellite of Gaia-Sausage-Enceladus. The combination of Gemini's large aperture with GHOST's high efficiency and broad spectral coverage makes this new spectrograph one of the leading instruments for near-field cosmology investigations.Comment: Submitted to MNRAS. 8 figures, 15page
