Image Representation of Time Series for Reinforcement Learning Trading Agent

The availability of diverse data has increased the demand for expertise in algorithmic trading strategies. Reinforcement learning has shown interesting applicability in a wide range of tasks, especially in some challenging problems as trading, where slow model convergence, inference speed, and reduced model accuracy appear as barriers in this type of application. In this paper, we propose the transformation of time series into images considering a transfer learning based on a semi-supervised model with deep Q learning agents, where labels were generated by an evolutionary algorithm to improve both training speed and performance measures. Resumo: A disponibilidade de dados diversos aumentou a demanda por conhecimento em estratégias de trading algorítmico. O aprendizado por reforço mostrou aplicabilidade interessante em uma ampla gama de tarefas, especialmente em alguns problemas desafiadores como negociação, onde a convergência lenta de modelos, velocidade de inferência e precisão reduzida do modelo aparecem como barreiras nesse para esse tipo de abordagem em ambientes reais. Neste artigo, propõe-se a transformação de séries temporais em imagens considerando o uso de transferência de aprendizado baseado em um modelo semisupervisionado com agentes de aprendizado profundo Q por reforço, onde os rótulos foram gerados por um algoritmo evolutivo para melhorar a velocidade do treinamento e as medidas de desempenho.

Influence of Trapped Gas on Pore Healing under Hot Isostatic Pressing in Nickel-Base Superalloys

Under the typical hot isostatic pressing (HIP) processing conditions, plastic deformation by dislocation slip is considered the primary mechanism for pore shrinkage, according to experimental observations and deformation mechanism maps. In the present work, a crystal plasticity model has been used to investigate the influence of applied pressure and holding time on porosity reduction in a nickel-base single crystal superalloy. The influence of trapped gas on pore shrinkage is modeled by coupling mechanical deformation with pore–gas interaction. In qualitative agreement with experimental investigations, we observe that increasing the applied pressure or the holding time can effectively reduce porosity. Furthermore, the effect of pore shape on the shrinkage is observed to depend on a combination of elastic anisotropy and the complex distribution of stresses around the pore. Simulation results also reveal that, for pores of the same shape, smaller pores (radius < 0.1 μm) have a higher shrinkage rate in comparison to larger pores (radius ≥ 0.1 μm), which is attributed to the increasing pore surface energies with decreasing pore sizes. It is also found that, for smaller initial gas-filled pores (radius < 0.1 μm), HIP can result in very high gas pressures (on the order of GPa). Such high pressures either act as a driving force for argon to diffuse into the surrounding metal during HIP itself, or it can result in pore re-opening during subsequent annealing or mechanical loading. These results demonstrate that the micromechanical model can quantitatively evaluate the individual influences of HIP processing conditions and pore characteristics on pore annihilation, which can help optimize the HIP process parameters in the future.
University of Nebraska UAS profiling during LAPSE-RATE

Abstract. This paper describes the data collected by the University of Nebraska-Lincoln (UNL) as part of the field deployment during the Lower Atmospheric Process Studies at Elevation – a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE) flight campaign in July 2018. UNL deployed two multirotor unmanned aerial systems (UASs) at various sites in the San Luis Valley (Colorado, USA) for data collection in support of three science missions: convection-initiation, boundary layer transition, and cold air drainage flow. We conducted 172 flights resulting in over 1300 minutes of cumulative flight time. Our novel design for the sensor housing onboard the UAS was employed in these flights to meet the aspiration and shielding requirements of the temperature/humidity sensors, and attempt to separate them from the mixed turbulent airflow from the propellers. Data presented in this paper include time-stamped temperature and humidity data collected from the sensors, along with the three-dimensional position and velocity of the UAS. Data are quality controlled and time-synchronized using a zero-order-hold interpolation without additional post processing. The full dataset is also made available for download at (https://doi.org/10. 5281/zenodo.4306086 (Islam et al. , 2020)).
SIFTing through satellite imagery with the Satellite Information Familiarization Tool

The Satellite Information Familiarization Tool (SIFT) is an open-source, multi-platform graphical user interface designed to easily display spectral and temporal sequences of geostationary satellite imagery. The Advanced Baseline Imager (ABI) and Advanced Himawari Imager (AHI) on the “new generation” of geostationary satellites collect imagery with a spatial resolution four times greater than previously available. Combined with the increased number of spectral bands and more frequent imaging, the new series imagers collect approximately 60 times more data. Given the resulting large file sizes, the development of SIFT is a multiyear effort to make those satellite imagery data files accessible to the broad community of students, scientists, and operational meteorologists. To achieve the objective of releasing software that provides an intuitive user experience to complement optimum performance on consumer-grade computers, SIFT was built to leverage modern graphics processing units (GPUs) through existing open-source Python packages, and runs on the three major operating systems: Windows, Mac, and Linux. The United States National Weather Service funded the development of SIFT to help enhance the satellite meteorology acumen of their operational meteorologists. SIFT has basic image visualization capabilities and enables the fluid animation and interrogation of satellite images, creation of Red-Green-Blue (RGB) composites and algebraic combinations of multiple spectral bands, and comparison of imagery with numerical weather prediction output. Open for community development, SIFT users and features continue to grow. SIFT is freely available with short tutorials and a user guide online. The mandate for the software, its development, realized applications, and envisioned role in science and training are explained.
Análise de Movimentos Compensatórios na Reabilitação de Membros Superiores através do Kinect

Assistive Robotics has been shown to be an important tool in the patient rehabilitation process. The rehabilitation of patients using traditional therapeutic approaches often ends up not achieving the expected results, as they come up against several factors, such as: repetition, duration, patient limit, among others, which could be minimized with the introduction of therapeutic approaches that use robotics, making these approaches gain more and more strength. With this, a series of new interventions started to be used in order to assist in the rehabilitation of patients with certain restrictions, especially those who suffered post-stroke trauma. Stroke patients often use the trunk to compensate for impaired upper limb motor function during rehabilitation training for that limb, which results in a reduced effect of rehabilitation training. Detecting trunk offsets can improve the effect of rehabilitation training. Therefore, this study aims to analyze the behavior of the movement of the trunk of four volunteers, who do not have any type of restriction, in the execution of four pre-established movements. The objective is to verify that, even if they do not have any type of restriction from the stroke, the volunteers make use of trunk movement to perform the pre-established movements. The Kinect v2 sensor was used to perform the data capture. Resumo: A Robótica Assistiva vem se mostrando uma importante ferramenta no processo de reabilitação de pacientes. A reabilitação de pacientes a partir de abordagens terapêuticas tradicionais acaba muitas vezes por não alcançar os resultados esperados, pois esbarram em diversos fatores, como: repetição, duração, limite do paciente, dentre outros, os quais poderiam ser minimizados com a introdução de abordagens terapêuticas que utilizam a robótica, fazendo com que estas abordagens passassem a ganhar cada vez mais força. Com isso, uma série de novas intervenções passaram a ser utilizadas com o intuito de auxiliar na reabilitação de pacientes com determinadas restrições, principalmente aqueles que sofreram traumas pós AVC. Os pacientes com AVC costumam usar o tronco para compensar a função motora do membro superior prejudicada durante o treinamento de reabilitação desse membro, o que resulta em um efeito reduzido do treinamento de reabilitação. Detectar compensações de tronco pode melhorar o efeito do treinamento de reabilitação. Sendo assim, este estudo tem o intuito de analisar o comportamento da movimentação do tronco de quatro voluntários, que não possuem nenhum tipo de restrição, na execução de quatro movimentos pré-estabelecidos. O objetivo é verificar se, mesmo não possuindo nenhum tipo de restrição oriunda do AVC, os voluntários fazem uso da movimentação do tronco para executar os movimentos pré-estabelecidos. O sensor Kinect v2 foi utilizado para realizar a captura dos dados.

Determination of stable carbon and hydrogen isotopes of light hydrocarbons

A combined system for the measurement of {sup 13}C/{sup 12}C and D/H ratios on light hydrocarbons (C{sub 1}-C{sub 3}) and CO{sub 2} is described. The system is designed for natural gas and sediment gas analyses. It comprises gas chromatographic separation with online combustion of hydrocarbons to CO{sub 2} and H{sub 2}O, reduction of H{sub 2}O to H{sub 2} on zinc in closed ampules, and mass spectrometric determination of isotope ratios ({delta}{sup 13}C, {delta}D) using a mass spectrometer inlet system especially designed for low hydrogen gas quantities. Isotope analyses can be carried out in the range of 3-10,000 {mu}L of CO{sub 2} and 100-10,000 {mu}L of H{sub 2} (gas quantities converted from sample compounds during preparation, STP). Including all preparation steps, reproducibility of isotope values for large sample quantities (>100 {mu}L of produced CO{sub 2} and >1,000 {mu}L of produced H{sub 2}). is {plus minus}0.2{per thousand} for {delta}{sup 13}C and {plus minus}3{per thousand} for {delta}D.
Solid‐State Luminescence and π‐Stacking in Crystalline Uranyl Dipicolinates

Crystal structure determinations on the hydrated forms of the complexes M2UO2(dipic)2, M = H, Rb, Cs, dipic = dipicolinate = pyridine-2,6-dicarboxylate, all of which show strong solid-state luminescence from the uranyl centre, have as a common feature extended π-stacking arrays of the dipicolinate ligands. Comparisons with related but non-luminescent complexes indicate that these stacking arrays may be associated with efficient energy transfer from the dipicolinate “antennae” to the uranyl unit.

Adsorption of aromatic compounds in large MFI zeolite crystals

Very large (180 × 40 × 40 µ3) and well defined crystals have been used in a gravimetric system to investigate the adsorption of aromatic compounds in MFI (silicalite) zeolite. The isotherms and isosteric heats of adsorption (Qst) were reported for future comparison with various adsorption models. Three types of phase transition were found. Isotherms of p-xylene showed a sharp step rise from ca. 4 to 8 molecules uc–1. A clear phase boundary could be outlined. Adsorbed benzene behaved as a dual-phase system in the range between 4.6 and 6 molecules uc–1. There were more phase transitions above 6 molecules uc–1 but it was not possible to outline the phase boundary. Molar entropy changes of 210 and 180 J mol–1 K–1 were found for the observed p-xylene–MFI and benzene–MFI phase transitions. For ethylbenzene and toluene, a dual-phase region was also observed but the transition was less pronounced. Isosteric heats, calculated from isotherms, showed a complex variation with loading and a strong dependence on temperature. It was also found that the adsorption kinetics are strongly influenced by the previous adsorption history. For freshly calcined samples the uptake rate was relatively fast. However, re-calcination after the adsorption of p-xylene created a diffusion barrier inside the crystalline material and subsequent adsorption of other aromatic compounds became much slower and displayed two-step kinetics.

Pathological Complete Response after Immune-Checkpoint Inhibitor Followed by Salvage Surgery for Clinical Stage IV Pulmonary Adenocarcinoma with Continuous Low Neutrophil-to-Lymphocyte Ratio: A Case Report

Immune-checkpoint inhibitors (ICIs) play a crucial role in the treatment of advanced nonsmall cell lung cancer (NSCLC); however, most patients fail this treatment after a limited period. We here report a patient with a pathological complete response after treatment with ICI for stage IV pulmonary adenocarcinoma. A 73-year-old man was referred to our hospital because of hoarseness. A roentgenogram and chest CT scan revealed a huge (78-mm diameter) pulmonary tumor in the right upper lobe and a tumor with cavitation in the left lower lobe. A CT scan also showed enlarged upper mediastinal lymph nodes (LNs). Transbronchial lung biopsy of the tumors showed adenocarcinomas in both. The tumor in the right upper lobe was considered to be the primary with mediastinal LNs metastasis and that in the left lower lobe a pulmonary metastasis. The disease was determined to be cT4N2M1a stage IVA. He was treated with first-line chemotherapy comprising cisplatin, pemetrexed, and bevacizumab for 6 cycles. However, 6 months after initial treatment, the primary and metastatic tumors enlarged, and he was treated with second-line anti-programed death 1 therapy for 7 months with a partial response. 18-fluorodeoxyglucose positron emission tomography (FDG-PET) revealed weak accumulation of FDG in the primary tumor only with no accumulation in the left pulmonary metastasis or mediastinal lymph node (LNs), despite the LNs still being enlarged. He was diagnosed as having ycT1bN0M0 stage IA2 disease and underwent right upper lobectomy. Postoperative pathological findings revealed that cancer tissues had been replaced by scar tissue and that CD4-positive T cells, rather than CD8-positive T cells, were predominant. It was also noted that he had a lower neutrophil-to-lymphocyte ratio (NLR) during immunotherapy than before immunotherapy and after surgery. He was diagnosed to be ypT0N0M0 stage 0 (Ef.3). His postoperative course was uneventful, and he remained well for 12 months after surgery with no further treatment. Neoadjuvant chemotherapy with ICIs for advanced NSCLC may be a promising modality, even for clinical stage IV disease, in the near future. Furthermore, NLR during immunotherapy may be a promising biomarker of ICIs treatment.
Effect of Limestone of Different Sizes on Soil Extractable Phosphorus and Its Concentrations in Grass and Clover Species

Phosphorus (P) is often reported as a nutrient whose availability increases by lime application, although some research suggests a decline in the short-term P availability upon liming. This study addresses the effects of applying different sized limestone (2–4, 0.5–2, 0.25–0.5, and <0.25 mm) on the forms and availability of soil P, P concentrations and extraction by pasture, and yields of plant species. Soil P was partitioned into organic and inorganic forms, using an ignition method. Available P was determined by the Olsen and Mehlich 3 methods. Phosphorus in plants was determined after acid digestion. Most P was present in organic form. One year after sowing, inorganic P increased and organic P decreased. Liming had no significant influences on soil P. Phosphorus extracted by Mehlich 3 explained 40% of the total dry-matter yield in the first harvest. No significant effect of liming on P concentration in plants was observed.

Summarizing abundance changes in waterbirds: some problems and a possible solution

After conducting replicated counts of migratory waterbirds at a given wetland, some authors choose to compute the mean abundance throughout the study period, whereas others report the peak value or the cumulative total. Here, we use fictitious and real examples to illustrate how some of these procedures can lead to distorted conclusions. For species with skewed abundance distributions, the mean does not summarize the central tendency in the data, and the median should be used; however, for many migratory waterbirds, median abundances at a given site can be null. Also, the probability of double-counting the same individuals increases when replicated surveys cover a long time. Moreover, since the cumulative abundance of a species/assemblage increases with the number of surveys, misleading results can be obtained if researchers apply different sampling efforts. Finally, the ranking and selection of wetlands for waterbird conservation can be misguided if cumulative totals are compared against standard criteria (i.e., Ramsar sites, IBAs). To avoid the above mentioned problems, we propose to use the maximum, peak abundance of a given waterbird species during the course of the study, or the sum of maxima, peak values across all the species in the same waterbird assemblage.
Communication Strategies for the 2030 Agenda Commitments: A Multivariate Approach

Companies are fully aware of the importance of including the Sustainable Development Goals (SDGs) in their corporate social responsibility (CSR) strategies, and of the importance of ensuring that the information disclosed allows groups to be identified. The business contribution to the 2030 Agenda is of interest, as it entails an accurate representation of company identity and is congruent with its contribution to the 2030 Agenda. For it, a content analysis of the business communication of 69 Spanish companies with their stakeholders was carried out in order to identify the possible existence of impression management practices. The evidence obtained indicates that although certain companies have adopted strategies to legitimise their contribution through self-promoting information or terms that allow diverting attention from irresponsible behaviour, companies that show a commitment to the 2030 Agenda do not make use of the information disclosed to manage stakeholder perceptions. Theoretically, our research contributes to increasing current knowledge about corporate communication strategies related to non-financial information, and identifying strategies to legitimise and manage impressions in the information related to the SDGs initiatives.
