title: Sensitivity of Landsat-8 OLI and TIRS Data to Foliar Properties of Early Stage Bark Beetle (Ips typographus, L.) Infestation

description: In this study, the early stage of European spruce bark beetle (Ips typographus, L.) infestation (so-called green attack) is investigated using Landsat-8 optical and thermal data. We conducted an extensive field survey in June and the beginning of July 2016, to collect field data measurements from a number of infested and healthy trees in the Bavarian Forest National Park (BFNP), Germany. In total, 157 trees were selected, and leaf traits (i.e. stomatal conductance, chlorophyll fluorescence, and water content) were measured. Three Landsat-8 images from May, July, and August 2016 were studied, representing early stage, advanced stage, and post-infestation, respectively. Spectral vegetation indices (SVIs) sensitive to the measured traits were calculated from the optical domain (VIS, NIR and SWIR), and canopy surface temperature (CST) was calculated from the thermal infrared band using the Mono-window algorithm. The leaf traits were used to examine the impact of bark beetle infestation on the infested trees and to explore the link between these traits and remote sensing data (CST and SVIs). The differences between healthy and infested samples regarding measured leaf traits were assessed using the Student’s t-test. The relative importance of the CST and SVIs for estimating measured leaf traits was evaluated based on the variable importance of the projection (VIP) obtained from the partial least square regression (PLSR) analysis. A temporal comparison was then made for SVIs with a VIP &gt; 1, including CST, using boxplot. Finally, the clustering method using a principal components analysis (PCA) was used to visually examine how well the two groups of sample plots (healthy and infested) are separated in 2-D space based on principal component scores. The results revealed that all measured leaf traits were significantly different (p &lt;0.05) between healthy versus infested samples, and CST was found to has a stronger correlation with all measured leaf traits compared to SVIs. Moreover, the study showed that CST was superior to the SVIs in detecting subtle canopy changes due to bark beetle infestation for the three months considered in this study. Results showed that CST is an essential variable for estimating measured leaf traits VIP &gt; 1, improving the results of clustering when used with other SVIs. The new insight offered by this study is that the stress induced by the early stage of bark beetle infestation is more pronounced by Landsat-8 thermal bands than the SVIs calculated from its optical bands. The potential of CST in detecting the green attack stage would have positive implications for the forest practice.

title: Understanding wheat lodging using multi-temporal Sentinel-1 and Sentinel- 2 data

description: Crop lodging assessment is essential for evaluating yield damage and informing crop management decisions for sustainable agricultural production. While a few studies have demonstrated the potential of optical and SAR data for crop lodging assessment, large-scale crop lodging assessment has been hampered by the unavailability of dense satellite time series data. The unprecedented availability of free Sentinel-1 and Sentinel-2 data may provide a basis for operational detection and monitoring of crop lodging. In this context, this study aims to understand the effect of lodging on backscatter/coherence and spectral reflectance derived from Sentinel-1 and Sentinel-2 data and to detect lodging incidence in wheat using time-series analysis. Crop biophysical parameters were measured in the field for both healthy and lodged plots from March to June 2018 in a study site in Ferrara, Italy, and the corresponding Sentinel images were downloaded and processed. The lodged plots were further categorised into different lodging severity classes (moderate, severe and very severe). Temporal profiles of backscatter, coherence, reflectance and continuum removed spectra were studied for healthy and lodging severity classes throughout the stem elongation to ripening growth stages. The Kruskal Wallis and posthoc Tukey tests were used to test for significant differences between different classes. Our results for Sentinel-2 showed that red edge (740 nm) and NIR (865 nm) bands could best distinguish healthy from lodged wheat (particularly healthy and very severe). For Sentinel-1, the analysis revealed the potential of VH backscatter and the complementarity of VV and VH/VV backscatter in distinguishing a maximum number of classes. Our findings demonstrate the potential of Sentinel data for near real-time detection of the incidence and severity of lodging in wheat. To the best of our knowledge, there is no study that has contributed to this application.

title: Assessing of knowledge and awareness of HPV and HIV among teenagers in Europe

description: Sexually transmitted infections appear to be an increasing problem in several European countries, especially among teenagers 16-19 years old. This may indicate that adolescents lack the necessary information and options which can help them lead healthy sexual and reproductive lives. In this work, basic sexually transmitted infections knowledge and awareness and comprehensive Human Papilloma Virus awareness of school-going adolescence aged 12-20 years was assessed using a systematic literature search and a multi-centric school-based survey. Results of this work can help point out areas where sexually transmitted diseases risk communication for adolescents needs to be improved.

title: An acid doped ice membrane for selective proton transport

description: Cation exchange membranes need to have high permselectivity for protons to make these membranes suitable for e.g. energy storage devices. Here, we present the proof of concept for a proton selective membrane made of hydrochloric acid doped ice. The proton selectivity of this acid doped ice membrane is the result of defects in the ice structure, caused by the acid. Ice membranes were made from different hydrochloric acid concentrations (0.1 M-2.0 M). The proton permselectivity of all ice membranes was above 99.7 % when both Na+ and K+ were present. The resistivity decreased exponentially with the concentration of acid in the ice membrane, reaching a value of 12 Ω.cm. The ice membranes were tested in an electrochemical cell using the Fe/Fe2+ and Fe2+/Fe3+ redox couples, and a power density of 7 W/m2 and OCV of 0.87 V was measured. The resistance of the ice membrane increased with time as protons moved from the ice structure, as determined from the higher pH of the ice after melting. These expelled protons (and corresponding counter charged ions) were not replaced by other mobile cations, indicating a permanent loss in conductivity, but not selectivity. To apply the ice membrane as a selective separator for protons in energy storage devices in the future, the membrane thickness should be reduced and the protons should be retained inside the ice.

title: Data of "Seasonal and diel variation in greenhouse gas emissions from an urban pond and its major drivers"

description: In this study, we investigated GHG emissions, seasonal and diel variation, and net ecosystem production (NEP) from an urban pond. In monthly 24-hour field campaigns during 11 months, diffusive water-atmosphere methane (CH4) and carbon dioxide (CO2) fluxes, CH4 ebullition and oxidation were quantified. With oxygen (O2) measurements, NEP was assessed. The pond was a net GHG source the entire year, with an emission of 3.4 kg CO2 eq m-2 yr-1. The dominant GHG emission pathway was CH4 ebullition (bubble flux, 50%), followed by diffusive emissions of CO2 (38%) and CH4 (12%). Sediment CH4 release was primarily driven by temperature and especially ebullition increased exponentially above a temperature threshold of 15 °C. The pond’s atmospheric CO2 exchange was not related to NEP or temperature, but likely to a high allochthonous carbon (C) input via runoff and anaerobic mineralization of C. We expect urban ponds to show a large increase in GHG emission with increasing temperature, which should be considered carefully when constructing ponds in urban areas. Emissions may partly be counteracted by pond management focusing on a reduction of nutrient and organic matter input.

title: Model overfitting using hyperspectral remote sensing

description: The growing number of narrow spectral bands in hyperspectral remote sensing improves the capacity to describe and predict biological processes in ecosystems. But it also poses a challenge to fit empirical models based on such high dimensional data, which often contain correlated and noisy predictors. As sample sizes, to train and validate empirical models, seem not to be increasing at the same rate, overfitting has become a serious concern. Overly complex models lead to overfitting by capturing more than the underlying relationship, and also through fitting random noise in the data. Many regression techniques claim to overcome these problems by using different strategies to constrain complexity, such as limiting the number of terms in the model, by creating latent variables or by shrinking parameter coefficients. This paper is proposing a new method, named Naïve Overfitting Index Selection (NOIS), which makes use of artificiallygenerated spectra, to quantify the relative model overfitting and to select an optimal model complexity supported by the data. The robustness of this new method is assessed by comparing it to a traditional model selection based on cross-validation. The optimal model complexity is determined for seven different regression techniques, such as partial least squares regression, support vector machine, artificial neural network and tree-based regressions using five hyperspectral datasets. The NOIS method selects less complex models, which present accuracies similar to the cross-validation method. The NOIS method reduces the chance of overfitting, thereby avoiding models that present accurate predictions thatare only valid for the data used, and too complex to make inferences about the underlying process.Published by: International Society for Photogrammetry and Remote Sensing, Inc.

title: Copula-based interpolation methods for air temperature data using collocated covariates

description: This paper introduces two copula-based interpolation methods to produce air temperature maps in a data-scarce area: a spatial copula interpolator including covariates, and a mixed copula interpolator. Daily mean air temperature was used from weather stations and ERA_Interim reanalysis weather data at 174 locations in the Qazvin Plain, Iran. The results showed an improved performance of the new methods to describe both spatial variability and co-variability between variables. The methods are potentially useful for other sparsely and irregularly distributed weather data.

title: Data of "Removal rate constants of organic micropollutants in activated sludge wastewater treatment plants are dependent on influent concentrations"

description: This data is part of a study that systematically explored whether OMP concentration affects removal rate constants, while correcting for environmental conditions and physicochemical properties. The aim of this study was to identify the influence of OMP influent concentration on the removal of OMPs in activated sludge WWTPs. To that end, we related removal rate constants of 58 OMPs obtained from 14 WWTPs to the OMP influent concentrations by applying a linear mixed effect modelling approach, also accounting for WWTP characteristics as well as physicochemical OMP properties. Our results showed that influent OMP concentration was indeed the most important explanatory variable for removal rate constants in our model and that the relationship between removal rate constant and concentration varied between OMPs. For most OMPs, the relationship was positive, except for valsartan and 2-hydroxyibuprofen. This is likely explained by toxic effects. Our results highlight the relevance of considering influent concentration in OMP fate predictions and may help in optimizing OMP removal strategies, for example by concentrating wastewater streams.

title: Antiretroviral pre-exposure prophylaxis (PrEP) for avoiding HIV in high-risk individuals

description: This study revised the search strategy and conducted an updated search of MEDLINE, the Cochrane Central Register of Controlled Trials and EMBASE in April 2017. The study also searched the WHO International Clinical Trials Registry Platform and ClinicalTrials.gov for ongoing trials. Data concerning outcomes, details of the interventions, and other study characteristics were extracted by two independent authors using a standardized data extraction form. Relative risk with a 95% confidence interval (CI) was used as the measure of effect. 12 randomized controlled trials that meet the criteria for the review were identified. Six were ongoing trials, four had been completed and two had been terminated early. Six studies with a total of 9849 participants provided data for this review. The trials evaluated the following: daily oral tenofovir disoproxil fumarate (TDF) plus emtricitabine (FTC) versus placebo; TDF versus placebo and daily TDF- FTC versus intermittent TDF-FTC. One of the trials had three study arms: TDF, TDF-FTC and placebo arm. The studies were carried out amongst different risk groups, including HIV-uninfected men who have sex with men, serodiscordant couples and other high-risk men and women

title: Plural Inheritance Laws, Practices and Emergent Types of Property—Implications for Updating the Land Register

description: Sustaining up-to-date land registers in the global south is an increasing concern for the protection of tenure, development of land markets and long-term sustainable planning practices and policy. It requires both the prompt reporting of land transfers and also an alignment between prevailing land rights and official recording systems. The literature on land registration highlights some effects of inheritance practices on the land register and land development. Taking these studies a step further, our research investigates how such effects evolve from the rules that guide inheritance practices using a qualitative research approach. We found that normative practices of inheritance mostly lead to communal property through numerous processes which have implications on the timing and likelihood of possible registration. Also, we found that the significance of land and buildings in the social context transcends the physical property per se and includes dimensions of spirituality and social identity. Our findings explain the misalignment between the official and social logics of property and suggest likelihood of non-reporting. We conclude that flexibility is required in recording communal rights in rural areas and that the transition to individual property is more likely in peri-urban and urban areas where the social logics of property have broken.

title: Yu and Ma 202208

description: The United Nations declareds 2021–2030 the ‘Decade of Healthy Ageing ’. Both individuals and society suffer from increasing rates of Alzheimer’s disease and other types of dementia (ADs). In 2019, these diseases contributed to a loss of 33.1 million years of healthy life globally. However, existing research has not fully analyzed the relationship among socioeconomic data and ADs. This study was designed to explore the relationship between Alzheimer’s disease rates and socioeconomic conditions in 120 countries. We used mixed effect models to investigate the relationship between the rates of ADs and socioeconomic data. The data was obtained from global databases, including from The Global Burden of Disease and World Bank. The socioeconomic data included information onf gender inequality, wealth inequality, and countries’ overall wealth. This study is among the first studies to put forward statistical evidence of a significant association between AD and other dementias among the elderly and socioeconomic inequality. These findings could help to inform the policies to be designed to improve the quality of interventions for ADs.
