ARMBench: An Object-centric Benchmark Dataset for Robotic Manipulation

This paper introduces Amazon Robotic Manipulation Benchmark (ARMBench), a large-scale, object-centric benchmark dataset for robotic manipulation in the context of a warehouse. Automation of operations in modern warehouses requires a robotic manipulator to deal with a wide variety of objects, unstructured storage, and dynamically changing inventory. Such settings pose challenges in perceiving the identity, physical characteristics, and state of objects during manipulation. Existing datasets for robotic manipulation consider a limited set of objects or utilize 3D models to generate synthetic scenes with limitation in capturing the variety of object properties, clutter, and interactions. We present a large-scale dataset collected in an Amazon warehouse using a robotic manipulator performing object singulation from containers with heterogeneous contents. ARMBench contains images, videos, and metadata that corresponds to 235K+ pick-and-place activities on 190K+ unique objects. The data is captured at different stages of manipulation, i.e., pre-pick, during transfer, and after placement. Benchmark tasks are proposed by virtue of high-quality annotations and baseline performance evaluation are presented on three visual perception challenges, namely 1) object segmentation in clutter, 2) object identification, and 3) defect detection.

Obtenção, tratamento e destinação de dióxido de carbono (CO2) a partir de emissões gasosas de incineradores

A incineração de lixo é uma atividade industrial química que produz emissões gasosas, cinzas e escórias inorgânicas, após a combustão total dos seus componentes. A sustentabilidade da incineração de lixo será crescente se for precedida de processos de catação e coleta seletiva (que constituem etapas de separação física, manual ou industrializada) de componentes sólidos pré-determinados, alguns dos quais podem sofrer processos de biodigestão e termoconversão em altas temperaturas. Os processos de termoconversão usuais de lixo incluem a destilação seca (pirólise) e a gasificação de componentes carbonáceos ou carbonosos de origem vegetal, animal e industrial e a incineração das frações restantes ou a queima completa de toda a carga coletada nas ruas, campos e edificações. As cinzas inorgânicas podem sofrer processos de classificação e concentração granulométrica para reciclagem nas indústrias de materiais de construção, que incluem as cerâmicas, os aglomerantes minerais, os refratários, vidros e vitro-cerâmicos, além de produtos compósitos. As emissões gasosas quentes dos processos de termoconversão ou termodestruição de resíduos sólidos, recém-geradas ou posteriormente depuradas para remoção das cinzas volantes, servem para cogerar vapor d´água superaquecido a ser consumido em turbinas geradoras de eletricidade. A presente abordagem trata da depuração das emissões gasosas dos processos de incineração do lixo, considerando também as rotas tecnológicas para pirólise e gasificação de resíduos sólidos urbanos, industriais e rurais, que são análogas. Um incinerador quando não opera em condições de combustão completa pode assumir as condições de uma retorta de pirólise ou de um gasificador, se ocorrer insuficiência ou ausência total do suprimento externo de oxigênio ou ar. As etapas do tratamento de depuração de gases destinam-se a produzir emissões gasosas purificadas, removendo cinzas e outras impurezas, admitindo que o dióxido de carbono (CO2) poderá ser captado, purificado e destinado para fins de consumo industrial ou reflorestamento. Os equipamentos das etapas depuradoras são: 1º - um ciclone para remover cinzas volantes acoplado a um banho coletor com solução de cal para neutralizar traços de cloro e gases ácidos absorvidos ou adsorvidos; 2º - um dispositivo de filtração com cal dolomítica para remover traços de cloro presentes nas emissões gasosas quentes; 3º - um sistema de resfriamento rápido da corrente gasosa ainda quente; 4º - um filtro de carvão ativo para remover frações orgânicas poluidoras, tais como as dioxinas e furanos; 5º - uma coluna lavadora de gases ácidos persistentes. Para captar e remover o dióxido de carbono das emissões gasosas depuradas, sugeriu-se adotar um processo consagrado, que inclui: a passagem por um separador de água, seguida da sua compressão e do seu resfriamento; o emprego de uma etapa mista de filtração em leito de peneira molecular e carvão ativo, cuja corrente de saída seria resfriada num condensador para posterior remoção de gases do ar atmosférico num segundo separador, daí sendo purificada numa coluna de destilação, dotada de um condensador de refluxo operando acoplada a uma unidade auxiliar de refrigeração, de onde sai para ser envasada

Human immunodeficiency virus and hepatitis C virus/hepatitis B virus co-infection in Southern Brazil: clinical and epidemiological evaluation

AbstractHepatitis B virus, hepatitis C virus and human immunodeficiency virus share a similar transmission pathway and are often diagnosed in the same patient. These patients tend to have a faster progression of hepatic fibrosis. This cross-sectional study describes the demographic features and clinical profile of human immunodeficiency virus/hepatitis co-infected patients in Paraná, Southern Brazil. A total of 93 human immunodeficiency virus-infected patients attending a tertiary care academic hospital in Southern Brazil were included. Clinical, demographic and epidemiological data were evaluated. Hepatitis B virus and/or hepatitis C virus positive serology was found in 6.6% of patients. The anti-hepatitis C virus serum test was positive in 85% (79/93) of patients, and the infection was confirmed in 72% of the cases. Eighteen patients (19%) were human immunodeficiency virus/hepatitis B virus positive (detectable HBsAg). Among co-infected patients, there was a high frequency of drug use, and investigations for the detection of co-infection were conducted late. A low number of patients were eligible for treatment and, although the response to antiretroviral therapy was good, there was a very poor response to hepatitis therapy. Our preliminary findings indicate the need for protocols aimed at systematic investigation of hepatitis B virus and hepatitis C virus in human immunodeficiency virus-infected patients, thus allowing for early detection and treatment of co-infected patients

Brazilian consortium for the study on renal diseases associated with COVID-19 : a multicentric effort to understand SARS-CoV-2-related nephropathy

Kidney involvement appears to be frequent in coronavirus disease 2019 (COVID-19). Despite this, information concerning renal involvement in COVID-19 is still scarce. Several mechanisms appear to be involved in the complex relationship between the virus and the kidney. Also, different morphological patterns have been described in the kidneys of patients with COVID-19. For some authors, however, this association may be just a coincidence. To investigate this issue, we propose assessing renal morphology associated with COVID-19 at the renal pathology reference center of federal university hospitals in Brazil. Data will come from a consortium involving 17 federal university hospitals belonging to Empresa Brasileira de Serviços Hospitalares (EBSERH) network, as well as some state hospitals and an autopsy center. All biopsies will be sent to the referral center for renal pathology of the EBSERH network. The data will include patients who had coronavirus disease, both alive and deceased, with or without pre-existing kidney disease. Kidney biopsies will be analyzed by light, fluorescence, and electron microscopy. Furthermore, immunohistochemical (IHC) staining for various inflammatory cells (i.e., cells expressing CD3, CD20, CD4, CD8, CD138, CD68, and CD57) as well as angiotensin-converting enzyme 2 (ACE2) will be performed on paraffinized tissue sections. In addition to ultrastructural assays, in situ hybridization (ISH), IHC and reverse transcription-polymerase chain reaction (RT-PCR) will be used to detect Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) in renal tissue. For the patients diagnosed with Collapsing Glomerulopathy, peripheral blood will be collected for apolipoprotein L-1 (APOL1) genotyping. For patients with thrombotic microangiopathy, thrombospondin type 1 motif, member 13 (ADAMTS13), antiphospholipid, and complement panel will be performed. The setting of this study is Brazil, which is second behind the United States in highest confirmed cases and deaths. With this complete approach, we hope to help define the spectrum and impact, whether immediate or long-term, of kidney injury caused by SARS-CoV-2

Profile of HIV subtypes in HIV/HBV- and HIV/HCV-coinfected patients in Southern Brazil

Abstract INTRODUCTION: HIV and viral hepatitis infections are major causes of chronic disease worldwide and have some similarities with regard to routes of transmission, epidemiology, front barriers faced during access of treatment, and strategies for a global public health response. The objective was to describe the HIV-1 subtypes, viral tropism and single-nucleotide polymorphisms (SNPs) of interleukin 28B (IL28B) from a case series of HIV/viral hepatitis coinfected patients from southern Brazil. METHODS: Clinical and epidemiological data were evaluated by a review of medical records. Periodic blood draws were taken to determine the viral and host characteristics. RESULTS: This study included 38 patients with HIV/HBV or HIV/HCV coinfection; the median age was 49 years. Thirty-seven (97.4%) were on antiretroviral therapy, 32 (84.2%) had an undetectable viral load, a median CD4+ T-cell count of 452 cells/mm3. HIV-1 subtyping showed 47.4 and 31.6% of patients with subtypes C and B, respectively. Analysis of viral co-receptor usage showed a predominance of the R5 variant (64.7%), with no significant difference between the subtypes. Twenty patients with HIV/HCV coinfection were eligible to receive HCV therapy with pegylated-interferon-alpha plus ribavirin, and 10/20 (50%) of them achieved sustained virological response. SNPs of IL28B were evaluated in 93.3% of patients with HIV/HCV coinfection, and 17 (60.7%) presented the CC genotype. CONCLUSIONS: In the present case series, a higher frequency of HIV subtype C was found in coinfected patients. However such findings need to be prospectively evaluated with the inclusion of data from regional multicenter analyses
