AbstractForest biomass is key in Earth carbon cycle and climate system, and thus under intense scrutiny in the context of international climate change mitigation initiatives (e.g. REDD+). In tropical forests, the spatial distribution of aboveground biomass (AGB) remains, however, highly uncertain. There is increasing recognition that progress is strongly limited by the lack of field observations over large and remote areas. Here, we introduce the Congo basin Forests AGB (CoFor-AGB) dataset that contains AGB estimations and associated uncertainty for 59,857 1-km pixels aggregated from nearly 100,000 ha of in situ forest management inventories for the 2000 – early 2010s period in five central African countries. A comprehensive error propagation scheme suggests that the uncertainty on AGB estimations derived from c. 0.5-ha inventory plots (8.6–15.0%) is only moderately higher than the error obtained from scientific sampling plots (8.3%). CoFor-AGB provides the first large scale view of forest AGB spatial variation from field data in central Africa, the second largest continuous tropical forest domain of the world.
Music, Language, and The N400: ERP Interference Patterns Across Cognitive Domains
Authors: Calma-Roddin Nicole , Drury John E. 
Published: July 2020

AbstractStudies of the relationship of language and music have suggested these two systems may share processing resources involved in the computation/maintenance of abstract hierarchical structure (syntax). One type of evidence comes from ERP interference studies involving concurrent language/music processing showing interaction effects when both processing streams are simultaneously perturbed by violations (e.g., syntactically incorrect words paired with incongruent completion of a chord progression). Here, we employ this interference methodology to target the mechanisms supporting long term memory (LTM) access/retrieval in language and music. We used melody stimuli from previous work showing out-of-key or unexpected notes may elicit a musical analogue of language N400 effects, but only for familiar melodies, and not for unfamiliar ones. Target notes in these melodies were time-locked to visually presented target words in sentence contexts manipulating lexical/conceptual semantic congruity. Our study succeeded in eliciting expected N400 responses from each cognitive domain independently. Among several new findings we argue to be of interest, these data demonstrate that: (i) language N400 effects are delayed in onset by concurrent music processing only when melodies are familiar, and (ii) double violations with familiar melodies (but not with unfamiliar ones) yield a sub-additive N400 response. In addition: (iii) early negativities (RAN effects), which previous work has connected to musical syntax, along with the music N400, were together delayed in onset for familiar melodies relative to the timing of these effects reported in the previous music-only study using these same stimuli, and (iv) double violation cases involving unfamiliar/novel melodies also delayed the RAN effect onset. These patterns constitute the first demonstration of N400 interference effects across these domains and together contribute previously undocumented types of interactions to the available pool of findings relevant to understanding whether language and music may rely on shared underlying mechanisms.

Published: July 2020

AbstractPteridine derivatives are intermediate metabolites of folic acid and its cofactors. Oxidized-form pteridines, but not reduced-form pteridines, are fluorescent substances. The purpose of this study was to clarify whether oxidized-form pteridine level in urine, estimated by spectrofluorometry, reflects oxidative stress in vivo. The subjects were healthy middle-aged men (n = 258). Urinary pteridine level was estimated by spectrofluorometry with an excitation wavelength of 360 nm and an emission wavelength of 450 nm. Relationships of urinary pteridines with oxidative stress markers (urinary DNA/RNA oxidation products and 15-isoprostane F2t) and with smoking were analyzed. Concentrations of pteridines, DNA/RNA oxidation products and 15-isoprostane F2t were used after logarithmic transformation in linear analyses. Pteridine levels were significantly correlated with levels of DNA/RNA oxidation products (Pearson’s correlation coefficient: 0.626, p < 0.01) and 15-isoprostane F2t (Pearson’s correlation coefficient: 0.695, p < 0.01). These correlations were not confounded by age, body mass index, history of smoking and estimated glomerular filtration rate in multivariate analysis. The mean urinary pteridine level was significantly higher in heavy smokers (16 cigarettes or more per day) than in nonsmokers and light smokers (less than 16 cigarettes per day) and was higher in light smokers than in nonsmokers. Thus, urinary fluorometric pteridine levels were shown to be associated with known biomarkers of oxidative stress as well as smoking, which causes oxidative stress in vivo. We propose spectrofluorometrical estimation of urinary pteridines as a simple and useful method for evaluation of oxidative stress in vivo.

AbstractThe development of novel strategies to augment motor training success is of great interest for healthy persons and neurological patients. A promising approach is the combination of training with transcranial electric stimulation. However, limited reproducibility and varying effect sizes make further protocol optimization necessary. We tested the effects of a novel cerebellar transcranial alternating current stimulation protocol (tACS) on motor skill learning. Furthermore, we studied underlying mechanisms by means of transcranial magnetic stimulation and analysis of fMRI-based resting-state connectivity. N = 15 young, healthy participants were recruited. 50 Hz tACS was applied to the left cerebellum in a double-blind, sham-controlled, cross-over design concurrently to the acquisition of a novel motor skill. Potential underlying mechanisms were assessed by studying short intracortical inhibition at rest (SICIrest) and in the premovement phase (SICImove), intracortical facilitation at rest (ICFrest), and seed-based resting-state fMRI-based functional connectivity (FC) in a hypothesis-driven motor learning network. Active stimulation did not enhance skill acquisition or retention. Minor effects on striato-parietal FC were present. Linear mixed effects modelling identified SICImovemodulation and baseline task performance as the most influential determining factors for predicting training success. Accounting for the identified factors may allow to stratify participants for future training-based interventions.

AbstractThe Tibetan chicken is a unique breed that has adapted to the high-altitude hypoxic conditions of the Tibetan plateau. A number of positively selected genes have been reported in these chickens; however, the mechanisms of gene expression for hypoxia adaptation are not fully understood. In the present study, eggs from Tibetan and Chahua chickens were incubated under hypoxic and normoxic conditions, and vascularization in the chorioallantoic membrane (CAM) of embryos was observed. We found that the vessel density index in the CAM of Tibetan chickens was lower than in Chahua chickens under hypoxia conditions. Transcriptomic and proteomic analyses of CAM tissues were performed in Tibetan and Chahua chicken embryos under hypoxic incubation using RNA-Seq and iTRAQ. We obtained 160 differentially expressed genes and 387 differentially expressed proteins that were mainly enriched in angiogenesis, vasculature development, blood vessel morphogenesis, blood circulation, renin-angiotensin system, and HIF-1 and VEGF signaling pathways. Twenty-six genes involved in angiogenesis and blood circulation, two genes involved in ion transport, and six genes that regulated energy metabolism were identified as candidate functional genes in regulating hypoxic adaptation of chicken embryos. This research provided insights into the molecular mechanism of hypoxia adaptation in Tibetan chickens.

AbstractHalving the proportion of the people without sustainable access to safe drinking water and basic sanitation is among the Sustainable Development Goals (SDG). Lack of access to safe drinking water has been associated with the prevalence of waterborne diseases. Due to this reported association, the development of household water treatment devices has been an alternative to improve the quality supply of domestic water. In this study, we aimed to evaluate the performance of a ceramic silver-impregnated pot filter (CSF) system coupled with an adsorption process, composed of silver-impregnated granular activated carbon and zeolite (CSF + GAC-Z), to remove waterborne bacteria Escherichia coli and Salmonella spp. from spiked water. The performance of this system was compared with the conventional CSF system. In this respect, we evaluated six CSF and six CSF + GAC-Z using spiked water with 103 and 102 CFU/mL of E. coli and Salmonella spp. The mean percentage of removals ranged between 98% and 99.98%. The highest bacterial removal efficiency was recorded by the CSF + GAC-Z (99%) and CSF (99.98%) for E. coli and Salmonella spp., respectively, but no significant statistical differences were found between filtration systems. Our findings suggest that the CSF + GAC-Z system was effective in the removal of waterborne bacteria from spiked water.

Abstract
We enrolled 122 patients with glioma who received surgery treatment in our hospital from June 2010 to May 2012, and 60 healthy individuals. We found that the plasma miR-720 in the glioma group was significantly higher than that in the healthy control group (3.19 ± 1.26 vs 0.98 ± 0.65, P&lt;0.001). The sensitivity and specificity were 71.3% (95%CI: 62.4–79.1%) and 83.3% (71.5–91.7%), respectively. The results indicated that the plasma miR-720 level was associated with tumor grade (t = 104.418, P&lt;0.001). The advanced tumor tended to have higher miR-720 expression level. No significant association was found between miR-720 and age, sex, tumor size, KPS and tumor position (P=0.438, 0.514, 0.518, 0.058, 0.226). The multivariate cox analysis indicated that the high expression of miR-720 (HR = 1.48, 95%CI: 1.12–2.97, P=0.023) was independently predictors of adverse prognosis in patients with glioma. The high expression of miR-720 was also associated with recurrence or development in patients with glioma (HR = 1.47, 95%CI: 1.18–3.14, P=0.012). Plasma miR-720 has a moderate diagnostic ability in early diagnostic of glioma and may be a potential tumor biomarker. The high plasma miR-720 was related to adverse prognosis in patients with glioma and could be a prognosis predictor of glioma patients.
The Speech “Bamana”: Using the Syllable Repetition Task to Identify Underlying Phonological Deficits in Children With Speech and Language Impairments
Authors: Roepke Elizabeth , Bower Kathryn E. , Miller Catherine A. , Brosseau-Lapré Françoise 
Published: July 2020

Purpose
This study compared performance on the Syllable Repetition Task (SRT) by preschoolers with diverse speech and language abilities to identify underlying impairments in speech processes.

Method
Three groups of 13 children ages 4 and 5 years with (a) typically developing (TD) speech and language, (b) speech sound disorder (SSD), and (c) comorbid developmental language disorder and speech sound disorder (DLD + SSD) completed the SRT. We calculated competence, memory, encoding, and transcoding scores, as well as word-initial stress pattern and vowel accuracy.

Results
A 3 × 3 (Group × Syllable length) factorial multivariate analysis of covariance revealed group differences for all measures and syllable length differences for memory, transcoding, and competence. There were no interactions between group and syllable length. TD children obtained the highest scores on each measure, though children with DLD + SSD performed similarly to TD children on encoding when vocabulary was included as a covariate. Children with SSD only outperformed children with DLD + SSD on competence and transcoding, and these two groups performed similarly on memory. A separate exploratory analysis using a 3 × 3 multivariate analysis of covariance revealed that children with DLD + SSD were more likely than children in the other groups to produce weak word-initial stress and vowel errors during syllable repetition.

Conclusion
Children with SSD and DLD + SSD exhibit underlying phonological deficits on the SRT compared to TD children. Results support the claim that memory and encoding are deficits in SSD. In addition, transcoding deficits were identified among children with no known oromotor impairment. Therefore, more research is required to identify the relationship between SRT performance and explicit measures of phonological processing.

Currently, Uzbekistan is in the process of legislation modernization, primarily in matters of labor protection and industrial safety. Modernization consists in the transition from a previously existing ineffective system focused on compensation payments to a modern system based on preventive approaches, which imply continuous improvement of work conditions. The aim of this work is to analyze the legislation in the field of labor protection management, obliging employers to proceed to occupational risks assessment and their management, as well as the assessment of occupational risks for miners, working under the influence of harmful and dangerous production factors during gold mining in the quarry, and the development of measures to reduce them.
The possible reasons for the discrepancy with the stated requirements of the physical factors of the miners working environment when performing work in gold mining quarries are analyzed. It has been established that professional risks for personnel are classified as high and medium and it is necessary to carry out organizational and technical measures to minimize them.
Social and technical differentiation in smart meter rollout: embedded scalar biases in automating Norwegian and Portuguese energy infrastructure
Authors: Sareen Siddharth 
Published: July 2020

AbstractWithin the energy geographies debate on the uneven scalar effects of energy transitions, this article addresses the under-examined, increasing intersection of automation and energy transitions. Using a comparative case of national smart meter rollouts—the deployment of distributed energy monitors whose diffusion constitutes the foundation for layering and automating energy infrastructure—it draws on two contrasting studies. One features an urban living lab during Norway’s rapidly completed smart meter rollout to 2.9 million consumers; the other targets the national scale in Portugal during its recently accelerated two-fifths completed smart meter rollout across six million consumers. The article identifies twin scalar biases: (i) social aspects of automation are controlled at higher scales while users are responsibilised for them at the household scale, and (ii) both control over and responsibility for technical aspects are restricted to higher scales. It empirically specifies how these scalar biases modulate socio-technical infrastructural interventions, such as smart meters. On this basis, it argues that embedding social and technical differentiation due to such scalar biases risks dehumanising technical aspects while detechnicising social aspects in this early intersection of energy transitions and automation.
Corpus-based contrastive studies
Authors: Hasselgård Hilde 
Published: July 2020

AbstractThis article outlines the beginnings of corpus-based contrastive studies with special reference to the development of parallel corpora that took place in Scandinavia in the early 1990s under the direction of Stig Johansson. It then discusses multilingual corpus types and methodological issues of their exploration, including thetertium comparationisfor contrastive studies based on different types of corpora. Some glimpses are offered of recent developments and current trends in the field, including the widening scope of corpus-based contrastive analysis, concerning language pairs as well as the kinds of topics studied and the methods used. The paper ends by identifying and discussing some challenges for the field and indicating prospects and directions for its future.
Questions in English and Swedish fiction texts
Authors: Axelsson Karin 
Published: July 2020

AbstractThe aim of this article is to shed new light on the use and translation of English and Swedish questions in fiction by using a combination of parallel and comparable corpus data extracted from the bidirectional English-Swedish Parallel Corpus. In particular, the study examines questions containing a question mark (QMquestions) categorised intowh-interrogatives, polar interrogatives, alternative questions, tag questions (including those with invariant tags), declarative questions,wh-fragments and non-wh-fragments. The parallel analysis shows that most QMquestion types are more often translated congruently into English than into Swedish. The focus is on types with low mutual correspondence scores: fragments, tag questions and declarative questions. The comparable analyses concern both bilingual contrasts between the original texts and monolingual contrasts between the translation and original subcorpora in both languages. The bilingual analysis aligns with several preliminary findings in the parallel analysis, e.g. the favouring of tag questions and some types ofwh-fragments in English. The monolingual analysis reveals both over- and underuse in translations and points to a strong effect of source-language influence.
Placement patterns of English and French conjunctive adjuncts of contrast
Authors: Dupont Maïté 
Published: July 2020

AbstractIn many languages, conjunctive adjuncts (e.g.however, therefore) are syntactically mobile. Several corpus-based contrastive studies have shown that languages differ in the positions that they tend to prefer for conjunctive adjuncts. However, the studies available have formulated general cross-linguistic differences in placement for languages as wholes, without considering the possibility that such contrasts may be influenced by register. The objective of this paper is to investigate and compare the placement patterns of English and French conjunctive adjuncts of contrast in two written registers (viz. editorials and research articles) in order to measure the impact of register variation on the differences between these two languages. The results suggest that, although register variation plays a significant role on placement within each language system, language is a better predictor of placement than register, since cross-linguistic differences in placement between English and French are stable across communicative situations. In a second stage, the results obtained in the comparable corpus study are complemented with the analysis of translation data, with a view to assessing the translators’ degree of awareness of the inherent word order preferences of the target language. The study is grounded in the framework of Systemic Functional Linguistics and relies on the notions of Theme and Rheme to describe conjunctive adjunct placement.
Dialogue vs. narrative in fiction
Authors: Oksefjell Ebeling Signe , Ebeling Jarle 
Published: July 2020

AbstractThis paper explores both comparable and translation data from the fiction part of the English-Norwegian Parallel Corpus (ENPC) in a new way. Rather than studying fiction as a unified register, we investigate to what extent fiction can be seen to contain (at least) two distinct registers – dialogue and narrative – and to what extent this may have implications for contrastive studies based on a corpus such as the ENPC. Token counts show that, although the texts are predominantly narrative in nature, the Norwegian texts are even more so than the English ones. On the basis of word lists, two items proportionally more frequent in dialogue and that had previously been studied on the basis of the fiction texts in the ENPC were identified and chosen for further scrutiny:thereandsee. Results from these two case studies uncover some differences in the use ofthereandseein dialogue vs. narrative, most conspicuously forseewhere its preferred use in dialogue is the cognition sense and in narrative the perception sense. Forthere, a noticeable difference is the choice of verb in the Norwegian translations of existentialthere-clauses in dialogue and narrative. In narrative, verbs other than verbs of existence are sometimes chosen, while this is never the case in dialogue.

Abstract
12-O-tetradecanoylphorbol-13-acetate (TPA), is a major active constituent of the seed oil of Croton tiglium L., has pharmacological activity for the treatment of acute myeloid leukemia patients. Diethyldithiocarbamate (DTC) is a potent inhibitor of NF-κB show activity of anticancer. In this study, we determined the effect of DTC and TPA in combination on HL-60 cells cultured in vitro and in vivo. In this study, we have shown that DTC and TPA synergistically inhibited the growth of HL-60 cells and strongly induced apoptosis in the cells. Mechanistic studies showed that the combined effects of DTC and TPA were associated with a decrease in Bcl-2. The animal experiment showed that the combination of DTC and TPA more potently inhibited the growth of HL-60 tumors than either agent alone. Our results indicate that the administration of TPA and DTC in combination may be an effective strategy for inhibiting the growth of acute myeloid leukemia cells.
