title: UMA ANÁLISE PSICANALÍTICA DO SOFRIMENTO DOS IDOSOS DURANTE A PANDEMIA

description: Segundo dados da Organização Mundial da Saúde, em 2025, os brasileiros serão a sexta população do mundo, com o maior número de idosos. Em um país com essa previsão, seria de esperar um comprometimento em relação ao bem-estar do idoso. Porém, não é isso o que aconteceu. O ano de 2020 ficará marcado como o ano de uma das mais drásticas epidemias já sofridas pela humanidade, o coronavírus. A chegada da pandemia ao Brasil tornou evidente a precária situação que muitos idosos sofrem e mais do que isso salientou uma série de estigmas em nossa sociedade sobre o papel do idoso. Buscamos discutir a abordagem psicanalítica em relação ao psiquismo dos idosos. Para isso, abordaremos quatro temáticas: a solidão, a dependência, o luto e a ansiedade. Por meio desses temas, defendemos a inserção dos idosos na análise psicanalítica, como uma via de tratamento. Sabemos que muitos dos traumas já existiam, mas com a pandemia, se tornaram mais evidentes.

title: Current Velocity, Wave Height, and Directional Data in the Lower Laguna Madre near South Padre Island, Texas, July 2022 to January 2023

description: The U.S. Geological Survey (USGS), in cooperation with the City of South Padre Island, Texas, deployed an acoustic Doppler current profiler (ADCP) to collect current velocity, wave height, and directional data in the lower Laguna Madre adjacent to South Padre Island, Texas. From July 19, 2022, through January 9, 2023, these data were collected at a site near South Padre Island (USGS station number 260551097100901) by using an up-looking acoustic doppler current profiler (ADCP) mounted on the bottom of the lower Laguna Madre. Raw data were collected at a frequency of 2 hertz (Hz); reported values were computed as the average of the processed data values for 60-minute intervals. All times are represented in Coordinated Universal Time (UTC).

title: Short-Term Variation in Mars Atmospheric Methane Concentrations Driven by Barometric Pumping

description: Measurements of atmospheric methane by the Curiosity rover’s SAM-TLS instrument are providing evidence of seasonality and diurnal variation in concentration. Given methane’s short atmospheric lifetime relative to geological timescales, its presence implies a replenishing source, and the observed variation demands the proposition of a modulation mechanism. This paper focuses on the modulation mechanism on a diurnal scale, extending earlier modeling of seasonal variation. Our modeling shows that barometric pumping driven by both diurnal and seasonal variation of atmospheric pressure, along with possible adsorption and desorption of methane in the shallow subsurface driven by temperature and pressure change, can explain the variation in methane concentration. In the model, an active, continuous, steady-state deep source of methane is assumed, and carbon dioxide serves as the carrier gas for drawing methane and possible trace gaseous constituents into the atmosphere.

title: Annual mass budget of Antarctic ice shelves from 1997-2021

description: Antarctic ice shelves moderate the contribution of the Antarctic Ice Sheet to global sea level rise by resisting the flow of ice into the ocean. However, the mass budget of Antarctic ice shelves and the impact of ice shelf mass change on grounded ice remain poorly constrained. Here, we present an annually partitioned ice shelf mass budget from 1997 to 2021 for all Antarctic ice shelves. Antarctic ice shelf mass decreased overall by 4,949 ± 1,499 Gt due to terminus retreat (4,818 ± 695 Gt), thinning (2,201 ± 1,401 Gt) and surface mass loss (24 ± 82 Gt), which were partially offset by increases in grounding line discharge (2094 ± 761 Gt). Thinning was the dominant mass loss term for the majority (65-86 %) of ice shelves that lost mass, but both thinning and retreat were equally related to increases in grounding line discharge. These observations provide a 24-year record of the state of Antarctic ice shelves, their freshwater inputs to the Southern Ocean and the impact of recent ice shelf mass change on grounding line discharge.

title: Detectability of the Yarkovsky Effect in the Main Belt

description: We attempt to detect signal of Yarkovsky-related acceleration in the orbits of 135 main belt asteroids (MBAs) we observed with the University of Hawai’i 88-inch telescope, supplemented with observations publicly available from the Minor Planet Center and Gaia Data Release 3. We estimated expected Yarkovsky acceleration values based on parameters derived through thermophysical modeling, but we were not able to find any reliable detections of Yarkovsky in our sample. Through tests with synthetic observations however, we estimated the minimum observational arc length needed to detect the Yarkovsky effect for all of our sample MBAs, which in nearly every case exceeded the current arc length of the existing observations. We find that the Yarkovsky effect could be detectable within a couple of decades of discovery for a 100-m MBA assuming 0.1′′ astrometric accuracy, which is at the size range detectable by the upcoming Vera Rubin Observatory Legacy Survey of Space and Time.

title: Microwave Observations of Venus with CLASS

description: We report on the disk-averaged absolute brightness temperatures of Venus measured at four microwave frequency bands with the Cosmology Large Angular Scale Surveyor (CLASS). We measure temperatures of 432.3 ± 2.8 K, 355.6 ± 1.3 K, 317.9 ± 1.7 K, and 294.7 ± 1.9 K for frequency bands centered at 38.8, 93.7, 147.9, and 217.5 GHz, respectively. We do not observe any dependence of the measured brightness temperatures on solar illumination for all four frequency bands. A joint analysis of our measurements with lower frequency Very Large Array (VLA) observations suggests relatively warmer (∼ 7 K higher) mean atmospheric temperatures and lower abundances of microwave continuum absorbers than those inferred from prior radio occultation measurements.

title: Solid State Curved Focal Plane Arrays Realized with Simple Approaches for Compact and High Performance Optical Systems

description: We present an overview of our work on design, development, and demonstration of simple and effective approaches to fabricating solid-state curved focal plane arrays (CFPAs) that has spawned a novel class of detector arrays that dramatically alter the capability and size of image systems, with an especially high impact in scientific and space applications in terms of science-instrument size, mass, simplicity, optical performance and cost. The key to the simplicity of our approaches to curved focal plane arrays, implemented in thick, high purity silicon or thinned membrane low resistivity substrate detectors, is that the curvature of the surface is independent of the VLSI fabrication process of imaging arrays. We present the principles of two approaches, results of fabrication of curved arrays, and results of analysis for limitation of curving silicon arrays. New concepts and techniques were also developed as spin offs of this program for extreme curvature FPAs and infrared CPFAs.

title: Bayesian weighting of climate models based on climate sensitivity

description: Using climate model ensembles containing members that exhibit very high climate sensitivities to increasing CO concentrations can result in biased projections. Various methods have been proposed to ameliorate this ‘hot model’ problem, such as model emulators or model culling. Here, we utilize Bayesian Model Averaging as a framework to address this problem without resorting to outright rejection of models from the ensemble. Taking advantage of multiple lines of evidence used to construct the best estimate of the earth’s climate sensitivity, the Bayesian Model Averaging framework produces an unbiased posterior probability distribution of model weights. The updated multi-model ensemble projects end-of-century global mean surface temperature increases of 2 C for a low emissions scenario (SSP1-2.6) and 5 C for a high emissions scenario (SSP5-8.5). These estimates are lower than those produced using a simple multi-model mean for the CMIP6 ensemble. The results are also similar to results from a model culling approach, but retain some weight on low-probability models, allowing for consideration of the possibility that the true value could lie at the extremes of the assessed distribution. Our results showcase Bayesian Model Averaging as a path forward to project future climate change that is commensurate with the available scientific evidence.

title: The salinity of coastal waters as a bellwether for global water cycle changes

description: While the global water cycle has been studied previously based on land and open ocean studies, here we use coastal satellite sea surface salinity (SSS) data to show that in global aggregate, SSS variations near coasts are strongly correlated with global water cycle variability driven by El Niño Southern Oscillation (ENSO). This is a significant finding as we demonstrate that open ocean SSS variability is not as sensitive to ENSO and global water cycle variability as the coastal oceans at interannual timescales. Aggregated global coastal SSS could therefore be used as a proxy for detection of changes in the large-scale cycling of water between the oceans and continents. Moreover, we identify major potential ‘hotspots’ on land and in the coastal ocean that tend to drive global coastal salinity variability, and which may consequently be most sensitive to future physical and biological impacts of water cycle changes on the coastal oceans.

title: Cliff collapse on Comet 67P/Churyumov-Gerasimenko - I. Aswan

description: The Aswan cliff on Comet 67P/Churyumov-Gerasimenko collapsed on 2015 July 10. Thereby, relatively pristine comet material from a depth of ~12m was exposed at the surface. Observations of the collapse site by the microwave instrument Rosetta/MIRO have been retrieved from 8 months prior to collapse, as well as from 5, 7, and 11 months post-collapse. The MIRO data are analysed with thermophysical and radiative transfer models. The pre-collapse observations are consistent with a 30 MKS thermal inertia dust mantle with a thickness of at least 3 cm. The post-collapse data are consistent with: 1) a dust/water-ice mass ratio of 0.9+/-0.5 and a molar CO2 abundance of ~30 per cent relative to water; 2) formation of a dust mantle after ~6 months, having a thickness of a few millimetres or a fraction thereof; 3) a CO2 ice sublimation front at 0.4 cm that withdrew to 2.0 cm and later to 20+/-6 cm; 4) a thermal inertia ranging 10-45 MKS; 5) a gas diffusivity that decreased from 0.1 m^2 s^-1 to 0.001 m^2 s^-1; 6) presence of a solid-state greenhouse effect parts of the time. The data and the analysis provide a firstempirical glimpse of how ice-rich cometary material ages and evolves when exposed to solar heating.

title: Numerical Simulation and Influence of Non-Gaussian Vibrations on the Design of Flexible Robotic Systems

description: Random vibration excitation is a widely used method to obtain dynamic properties of structures and is commonly applied as a loading condition for aerospace structures. Random vibration spectra are defined most commonly through a power spectral density (PSD) curve which provides the magnitude of the excitation as a function of frequency. A typical analysis for the vibrational response of structures designed with aerospace applications is the application of a predefined PSD curve representing vibrations from launch, landing, or operation. Shakerbased random excitation and traditional finite element analysis techniques employ random vibrations assuming a Gaussian distribution of excitation impulse magnitudes. In reality, while some vibrational environments may be adequately described by Gaussian signals, many true excitations have non-Gaussian properties. A non-Gaussian signal is one that has a skewness or kurtosis not aligned with typical values of a Gaussian distribution. Non-Gaussian random vibrations contain vibrational impulses magnitudes larger than those found in a Gaussian signal and could damage a system if not considered. Flexible systems, notably flexible robotic systems, often manifest dynamic nonlinearities which may produce magnified responses to these impulses. This paper examines two case studies of robotic rover chassis architectures: NASA JPL’s Pop-Up Flat Folding Explorer Robot (PUFFER) and Cooperative Autonomous Distributed Robotic Explorer (CADRE). PUFFER has a flexible architecture and CADRE has a rigid chassis. The influence of non-Gaussian random vibrations on each system is examined and results are presented to aid in the design of flexible robotic systems. The results indicate that Non-Gaussian excitation should be considered in the design of flexible robotic systems and that a typical enveloping procedure, such as a 3dB increase of the input PSD for a Gaussian random vibe excitation, did not bound the response of PUFFER subjected to a non-Gaussian excitation.

title: Direct Measurements of Stellar Masses with the Habitable World Observatory

description: Background stars within ∼1′′ of a nearby massive object will have their centroids shift by about 1 mas due to microlensing. This provides mass measurements of stellar mass objects in the solar neighborhood. Habitable Worlds Observatory (HWO) targets towards the Galactic Bulge will have a sufficient density of background stars that HWO will be able to measure their masses independently of stellar evolutionary models, which will allow more accurate habitable histories of their exoplanets to be evaluated. This opportunity is maximized for designs of HWO with very high contrasts (∆mag ≳ 25) and the capability for precise relative astrometry with respect to the target star. HWO can apply this technique to any nearby stellar mass object in the direction of the Galactic Bulge, enhancing its science case and that of precursor missions like Roman.

title: Volatiles in the H2O and CO2 ices of comet 67P/Churyumov-Gerasimenko

description: ABSTRACT ESA’s Rosetta spacecraft at comet 67P/Churyumov-Gerasimenko (67P) was the first mission that accompanied a comet over a substantial fraction of its orbit. On board was the ROSINA mass spectrometer suite to measure the local densities of the volatile species sublimating from the ices inside the comet’s nucleus. Understanding the nature of these ices was a key goal of Rosetta. We analyzed the primary cometary molecules at 67P, namely H2O and CO2, together with a suite of minor species for almost the entire mission. Our investigation reveals that the local abundances of highly volatile species, such as CH4 and CO, are reproduced by a linear combination of both H2O and CO2 densities. These findings bear similarities to laboratory-based temperature programmed desorption experiments of amorphous ices and imply that highly volatile species are trapped in H2O and CO2 ices. Our results do not show the presence of ices dominated by these highly volatile molecules. Most likely, they were lost due to thermal processing of 67P’s interior prior to its deflection to the inner solar system. Deviations in the proportions co-released with H2O and CO2 can only be observed before the inbound equinox, when the comet was still far from the sun and the abundance of highly volatile molecules associated with CO2 outgassing were lower. The corresponding CO2 is likely seasonal frost, which sublimated and lost its trapped highly volatile species before re-freezing during the previous apparition. CO, on the other hand, was elevated during the same time and requires further investigation

title: Light propagation in the presence of multiple stellar gravitational lenses

description: We discuss the light propagation in the presence of multiple gravitational lenses. For that we assume that lenses are separated by large distances from each other and thus are non-interacting. Furthermore, we consider a rather exotic case when the source, the lenses, and the observer are positioned on the same line. It turned out that in this axially-symmetric case, the diffraction integrals are exactly solvable providing us with valuable analytical insights. We observe that the number of Einstein rings formed around each subsequent lens doubles. The overall light amplification depends on the masses of the lenses and is driven by the distance between them. We demonstrate that for practical observing scenarios, the two lens system does not provide for an additional light amplification compared to the case with a single lens transmission. However, the use of the second lens may bring some technical advantages including significant beam compression, improved beam quality, increased signal power density, and potential use of smaller size telescopes at the receiver.

title: Physical Characterization of Moon Impactor WE0913A

description: On March 4, 2022, the object provisionally known as WE0913A crashed into the Moon after several close flybys of the Earth and the Moon in the previous three months. Leading up to impact, the true identity of the lunar-impactor was up for debate with two possibilities: the Falcon 9 rocket from the DSCOVR mission or the Long March 3C from the Chang’e 5-T1 mission. In this paper, we present a trajectory and spectroscopic analysis using ground-based telescope observations to show conclusively that WE0913A is the Long March 3C R/B from the Chang’e 5-T1 mission. Analysis of photometric light curves collected before impact give a spin period of 185.221 ± 6.540 s at a 1σ confidence level just before the first close Earth fly-by on January 20, 2022, and a period of 177.754 ± 0.779 s at a 1σ confidence level just before the second close Earth fly-by on February 8, 2022. Using Markov Chain Monte Carlo sampling and a predictive light curve simulation based on an anisotropic Phong reflection model, we estimate both physical and dynamical properties of the Chang’e 5-T1 rocket body at the start of an observation epoch. The results from the Bayesian analysis imply that there may have been additional mass on the front of the rocket body. Using our predicted impact location on the lunar surface, the Lunar Reconnaissance Orbiter was able to find and image the crater site approximately 7.5 km from prediction. Comparing the pre- and post-impact images of the location shows two distinct craters side-by-side that were made by the Chang’e 5-T1 R/B. The double crater supports the hypothesis that there was possibly an additional mass at the front of the rocket body.

title: Quantifying the dependence of drop spectrum width on cloud drop number concentration for cloud remote sensing

description: In-situ measurements of liquid cloud and precipitation drop size distributions from aircraft probes are used to examine the relationship of the width of drop size distributions to cloud drop number. The width of the size distribution is quantified in terms of the parameter k=(rv/re)3, where rv is the volume mean radius and re is the effective radius of the distributions. We find that on small spatial scales (~100 m), k is positively correlated with cloud drop number. This correlation is robust across a variety of campaigns using different probe technology. A new parameterization of k versus cloud drop number is developed. This new parameterization of k is used in an algorithm to derive cloud drop number in liquid phase clouds using satellite measurements of cloud optical depth and effective radius from the MODIS sensor on Aqua. This algorithm is compared to the standard approach to derive drop number concentration that assumes a fixed value for k. The new parameterization generally increases the derived number concentration over ocean, where N is low, and decreases it over land, where N is high. The general tendency of the parameterization is to narrow the distribution of derived number concentration. Regional biases are as large as 20% with the magnitude of the bias closely tracking the regional mean number concentration. Interestingly, biases are smallest in regions of frequent stratocumulus cloud cover, which are a regime of significant interest for study of the aerosol indirect effect on clouds.

title: Results from the First Year and a Half of Mars 2020 Robotic Operations

description: Mars 2020 Robotic Operations is responsible for the development, planning and Mars execution of robotics aspects of the mission. This includes the Perseverance rover’s mobility, manipulation, and sampling operations, and the Ingenuity helicopter’s flights. As of October 2022 (Martian Solar Day 562, or sol 562), the rover has driven 12101.7m and collected 15 samples, while the helicopter has logged 32 flights, covering 7281m, with an overall flight time of 3467 seconds. Perseverance and Ingenuity have accomplished several firsts such as coring and caching samples autonomously, and demonstrating powered flight on Mars. Perseverance has also set new planetary rover records such as the longest continuation drive distance (699.9m with no human review), longest single-sol autonomous drive distance (329m), and total autonomously evaluated drive distance (11,141m out of 12,409m total, i.e. 89\% of all driving, an order of magnitude more than previous NASA Mars rover missions). This paper presents results from the first year and a half of Mars operations to highlight the operations approach that enabled this success, the challenges encountered, and lessons learned.
