AbstractRapid and uncontrolled urbanization in tropical Africa is increasingly leading to unprecedented socio-economical and environmental challenges in cities, particularly urban heat and climate change. The latter calls for a better representation of tropical African cities’ properties relevant for urban climate studies. Here, we demonstrate the possibility of collecting urban canopy parameters during a field campaign in the boreal summer months of 2018 for deriving a Local Climate Zone (LCZ) map and for improving the physical representation of climate-relevant urban morphological, thermal and radiative characteristics. The comparison of the resulting field-derived LCZ map with an existing map obtained from the World Urban Data and Access Portal Tool framework shows large differences. In particular, our map results in more vegetated open low-rise classes. In addition, site-specific fieldwork-derived urban characteristics are compared against the LCZ universal parameters. The latter shows that our fieldwork adds important information to the universal parameters by more specifically considering the presence of corrugated metal in the city of Kampala. This material is a typical roofing material found in densely built environments and informal settlements. It leads to lower thermal emissivity but higher thermal conductivity and capacity of buildings. To illustrate the importance of site-specific urban parameters, the newly derived site-specific urban characteristics are used as input fields to an urban parametrization scheme embedded in the regional climate model COSMO-CLM. This implementations decreases the surface temperature bias from 5.34 to 3.97 K. Based on our results, we recommend future research on tropical African cities to focus on a detailed representation of cities, with particular attention to impervious surface fraction and building materials.

AbstractPLA2G6 is the causative gene for a group of autosomal recessive neurodegenerative disorders known as PLA2G6-associated neurodegeneration (PLAN). We present a case with early-onset parkinsonism, ataxia, cognitive decline, cerebellar atrophy, and brain iron accumulation. Sequencing of PLA2G6 coding regions identified only a heterozygous nonsense variant, but mRNA analysis revealed the presence of an aberrant transcript isoform due to a novel deep intronic variant (c.2035-274G > A) leading to activation of an intronic pseudo-exon. These results expand the genotypic spectrum of PLAN, showing the paramount importance of detecting possible pathogenic variants in deep intronic regions in undiagnosed patients.

AbstractThe region around the plant root referred to as the rhizosphere, is the zone where various microbial activity occurs. It performs crucial functions such as increasing the uptake of nutrients for plant development and preventing plant against plant pathogens. Keeping in mind the beneficial role performed by rhizospheric microorganisms, rhizobacterial species were isolated from the maize and soybean plant's rhizosphere. The isolated microorganisms were evaluated for their biochemical characteristics, plant growth-promoting potentials, tolerance to different environmental conditions, and their antifungal activity against Fusarium graminearum, a fungal pathogen that infects maize. The rhizobacterial isolates with multiple plant growth-promoting potentials were identified as Bacillus spp (80.77%), Rhodocyclaceae bacterium (3.85%), Enterococcus spp (3.85%). Massilia spp (3.85%. and Pseudomonas (7.69%) species based on their 16S rRNA molecular characterization. The bacterial isolates possessed antifungal activities against Fusarium graminearum, promote maize and soybeans seed under laboratory conditions, and exhibited different levels of tolerance to pH, temperature, salt, and heavy metal. Based on this, the whole genome sequencing of Bacillus sp. OA1, Pseudomonas rhizosphaerea OA2, and Pseudomonas sp. OA3 was performed using Miseq Illumina system to determine the functional genes and secondary metabolites responsible for their plant growth-promoting potential Thus, the result of this research revealed that the selected bacterial isolates possess plant growth-promoting potentials that can make them a potential candidate to be employed as microbial inoculants for protecting plants against phytopathogens, environmental stress and increasing plant growth and productivity.
The Role of Emotion Projection, Sexual Desire, and Self-Rated Attractiveness in the Sexual Overperception Bias
Authors: Samara Iliana , Roth Tom S. , Kret Mariska E. 
Published: August 2021

AbstractA consistent finding in the literature is that men overperceive sexual interest in women (i.e., sexual overperception bias). Several potential mechanisms have been proposed for this bias, including projecting one’s own interest onto a given partner, sexual desire, and self-rated attractiveness. Here, we examined the influence of these factors in attraction detection accuracy during speed-dates. Sixty-seven participants (34 women) split in four groups went on a total of 10 speed-dates with all opposite-sex members of their group, resulting in 277 dates. The results showed that attraction detection accuracy was reliably predicted by projection of own interest in combination with participant sex. Specifically, men were more accurate than women in detecting attraction when they were not interested in their partner compared to when they were interested. These results are discussed in the wider context of arousal influencing detection of partner attraction.
Estimating intergenerational income mobility on sub-optimal data: a machine learning approach
Authors: Bloise Francesco , Brunori Paolo , Piraino Patrizio 
Published: August 2021

AbstractMuch of the global evidence on intergenerational income mobility is based on sub-optimal data. In particular, two-stage techniques are widely used to impute parental incomes for analyses of lower-income countries and for estimating long-run trends across multiple generations and historical periods. We propose applying machine learning methods to improve the reliability and comparability of such estimates. Supervised learning algorithms minimize the out-of-sample prediction error in the parental income imputation and provide an objective criterion for choosing across different specifications of the first-stage equation. We use our approach on data from the United States and South Africa to show that under common conditions it can limit the bias generally associated to mobility estimates based on imputed parental income.
A roadmap to Durable BCTV Resistance Using Long-Read Genome Assembly of Genetic Stock KDH13
Authors: Galewski Paul J. , Eujayl Imad 
Published: August 2021

AbstractBeet Curly Top (BCT) is a viral disease which negatively impacts crop productivity for sugar beet growers and the sugar beet industry in the western USA and dry regions worldwide. Current varieties exhibit little genetic resistance to the Beet Curly Top Virus (BCTV), suggesting there is a large potential for improvement. KDH13 (PI 663862) is a double-haploid line created from a population (C762-17/PI 560130) which segregates for resistance to BCTV and was identified as genetic stock for the improvement of sugar beet varieties. PacBio sequences were generated and assembled to better define the content and organization of variation within the KDH13 genome and to provide resources to identify specific variation underpinning durable genetic resistance. Using ab initio predicted proteins as anchors, the assembled KDH13 contigs were placed in a more contiguous order using the EL10.1 reference genome, which leveraged Bio-Nano optical maps and Hi-C proximity information for chromosome level scaffolding. In total, 4681 (75%) of the 6245 contigs were placed in the order and orientation of the EL10.1 genome. The anchored contigs represented 502,929,268 bp (87.7%), the KDH13 genome assembly. An F1 hybrid and parental lines KDH13 (resistant) and KDH19-17 (susceptible) were sequenced using Illumina technology in order to characterize the SNP, indel, and structural variation between parental lines and allow for a more detailed investigation into causal variation linked to important phenotypes. In total, 3,086,720 variants were detected, including 2,259,324 single-nucleotide polymorphisms, 191,448 insertions, 198,057 deletions, 268,090 complex substitutions, 90,004 multi allelic variants, and 79,797 structural variants. Of the total variation, 1,158,491 were informative in the F1 and were able to discriminate between the two parents. This information represents a high-density marker dataset distributed globally across the sugar beet genome and can be used to track genomic segments in populations where KDH13 is used as parental material to improve BCTV resistance.
Teacher Orchestration of Language and Gesture in Explaining Science Concepts in Images

Published: August 2021

AbstractStudents’ difficulties interpreting diagrams remain a concern in science education. Research about improving diagram comprehension has included few studies of teachers’ orchestration of language and gesture in explaining diagrams—and very few in senior high schools. Research with younger students and studies of research scientists’ practice indicate the significance of the interaction of teachers’ gesture and language in explaining visualisations. The strategic deployment of such teacher-focussed authoritative explanations has been observed in facilitating progression to more complex and symbolic representations in classroom work. However, the paucity of such research in senior high school leaves open the question of how these teachers use gesture and language in managing the challenges of explaining the intricate sub-microscopic and abstract visualisations senior high school students need to negotiate. In this paper, we outline existing studies of teachers’ use of gesture and language to explain complex images in senior high school and investigate how it is managed by two biology teachers with images of different types and complexity representing the activity of certain cell components in the early phase of cell duplication. Implications are drawn for foci of further research including the role of a metalanguage describing different types of visualisations and their affordances.
Is there a relationship between sleep apnoea and microalbuminuria?
Authors: Cihanbeylerden Melek , Yüceege Melike Bağnu 
Published: August 2021

Abstract
Introduction
Obstructive sleep apnoea (OSA) is a cause of hypoxia, and the correlation between hypoxia and microvascular complications is well known. Microalbuminuria (MAU) is a marker for endovascular dysfunction and an indicator of cardiovascular events and all-cause mortality in the general population. The aim of this study was to investigate the relationship between microvascular damage and the metabolic complications of OSA based on the presence of MAU.

Material and method
Urinary albumin/creatinine ratio (ACR) and microalbumin level were examined in patients with an apnoea-hypopnoea index (AHI) greater than 5/h (study group) and in patients with an AHI less than 5/h (control group). The exclusion criteria were other possible causes of MAU (hypertension, nephropathy, coronary artery disease, and severe thyroid dysfunction).

Results
Of 103 patients enrolled, 80 formed the group with OSA and 23 served as controls. According to the AHI values, the patients were divided into four groups as normal, mild, moderate and severe. There was no significant difference between the four groups in terms of the microalbumin level and urinary albumin/creatinine ratio.

Conclusion
In this study, no significant relationship was found between MAU and sleep apnoea.
The Non-identity Problem and the Psychological Account of Personal Identity
Authors: Blackshaw Bruce P. 
Published: August 2021

AbstractAccording to the psychological account of personal identity, our identity is based on the continuity of psychological connections, and so we do not begin to exist until these are possible, some months after conception. This entails the psychological account faces a challenge from the non-identity problem—our intuition that someone cannot be harmed by actions that are responsible for their existence, even if these actions seem clearly to cause them harm. It is usually discussed with regard to preconception harms, but in the context of the psychological account, it is also applicable to prenatal harms. Inflicting prenatal injury is widely thought to be morally impermissible, but if the injury is identity-determining on the psychological account, then no-one seems to be harmed—rather, the injury is responsible for bringing them into existence. Here, I argue that identity-determining injuries can routinely occur on the psychological account, and that this undermines the account. I assess Nicola Williams’ proposal to salvage the account based on a trans-world account of personal identity, and show that it is unsuccessful. I then show that Jeff McMahan’s embodied mind account of personal identity is also susceptible. I conclude that identity-determining prenatal injuries pose a significant challenge for the psychological account and its variants, and provide a reason for supporting alternative accounts that fix personal identity at conception.
Sequential analyses of bovid tooth enamel and dentine collagen (δ18O, δ13C, δ15N): new insights into animal husbandry between the Late Neolithic and the Early Bronze Age at Tana del Barletta (Ligurian Prealps)

Published: August 2021

AbstractTana del Barletta is an upland cave used from the Late Neolithic to the Middle Bronze Age, located in the vicinity of the coast in Liguria (NW Italy). The excavation revealed the presence of a faunal assemblage dominated by caprine and cattle remains. In order to gain new data on late prehistoric farming strategies (e.g. seasonal mobility, coastal grazing, animal diet), intra-tooth series of stable oxygen and carbon isotopes have been obtained from cattle and sheep/goat tooth enamel, along with intra-tooth series of nitrogen and carbon isotopes from cattle dentine collagen. Due to the prevalence of maxillary teeth, a modern calf has also been analysed to assess intra-individual isotopic differences between the maxillary and mandibular dentition. Modern data on oxygen isotope values of meteoric water from different altitudes around the area of the site were used as a reference for interpretation. The results indicate that the water ingested by the herd was mostly characterised by particularly low δ18O values, highlighting the importance of the uplands for the late prehistoric farmers of the region. However, the input of water sourced from lower elevations, especially during the winter months, cannot be dismissed. In addition, the nitrogen isotopic composition of cattle collagen rules out the ingestion of salt-tolerant vegetation or seaweed, suggesting that grazing did not occur directly on the coastal plain.
Constructing the Past: the Relevance of the Narrative Self in Modulating Episodic Memory
Authors: Dings Roy , Newen Albert 
Published: August 2021

AbstractEpisodic memories can no longer be seen as the re-activation of stored experiences but are the product of an intense construction process based on a memory trace. Episodic recall is a result of a process of scenario construction. If one accepts this generative framework of episodic memory, there is still a be big gap in understanding the role of the narrative self in shaping scenario construction. Some philosophers are in principle sceptic by claiming that a narrative self cannot be more than a causally inefficacious attributed entity anyway. Thus, we first characterize a narrative self in detail and second we clarify its influential causal role in shaping our episodic memories by influencing the process of scenario construction. This happens at three stages, namely at the level of the input, the output and the process of scenario construction.

AbstractTo construct wild-type E. coli irp2 gene deletion strains, CRISPR/Cas9 gene editing technology was used, and the difficulty and key points of gene editing of wild-type strains were analyzed. Based on the resistance of the CRISPR/Cas9 system expression vector, 4 strains of 41 E. coli strains isolated from Saba pigs were selected as the target strains for the deletion of the irp2 gene, which were sensitive to both ampicillin and kanamycin. Then, CRISPR/Cas9 technology was combined with homologous recombination technology to construct recombinant vectors containing Cas9, sgRNA and donor sequences to knock out the irp2 gene. Finally, the absence of the irp2 gene in E. coli was further verified by iron uptake assays, iron carrier production assays and growth curve measurements. The results showed that three of the selected strains showed single base mutations and deletions (Δirp2-1, Δirp2-2 and Δirp2-3). The deletion of the irp2 gene reduced the ability of E. coli to take up iron ions and produce iron carriers, but not affect the growth characteristics of E. coli. It is shown that the CRISPR/Cas9 knock-out system constructed in this study can successfully knock out the irp2 gene of the wild-type E. coli. Our results providing new insights into genome editing in wild-type strains, which enable further functional studies of the irp2 gene in wild-type E. coli.

Published: August 2021

AbstractNonholonomic mechanics describes the motion of systems constrained by nonintegrable constraints. One of its most remarkable properties is that the derivation of the nonholonomic equations is not variational in nature. However, in this paper, we prove (Theorem 1.1) that for kinetic nonholonomic systems, the solutions starting from a fixed pointqare true geodesics for a family of Riemannian metrics on the image submanifold$${{\mathcal {M}}}^{nh}_q$$Mqnhof the nonholonomic exponential map. This implies a surprising result: the kinetic nonholonomic trajectories with starting pointq, for sufficiently small times, minimize length in$${{\mathcal {M}}}^{nh}_q$$Mqnh!
Pyrite (FeS2)-supported ultrafiltration system for removal of mercury (II) from water

Published: August 2021

AbstractThis study investigated the Hg(II) removal efficiencies of the reactive adsorbent membrane (RAM) hybrid filtration process, a removal process that produces stable final residuals. The reaction mechanism between Hg(II) and pyrite and the rejection of the solids over time were characterized with respect to flux decline, pH change, and Hg and Fe concentration in permeate water. Effects of the presence of anions (Cl−, SO42−, NO3−) or humic acid (HA) on the rejection of the Hg(II)-contacted pyrite were studied. The presence of both HA and Hg(II) increased the rate of flux decline due to the formation of irreversible gel-like compact cake layers as shown in the experimental data and modeling related to the flux decline and the SEM images. Stability experiments of the final residuals retained on the membrane using a thiosulfate solution (Na2S2O3) show that the Hg(II)-laden solids were very stable due to little or no detection of Hg(II) in the permeate water. Experiment on the possibility of continuously removing Hg(II) by reusing the Hg/pyrite-laden membrane shows that almost all Hg(II) was adsorbed onto the pyrite surface regardless of the presence of salts or HA, and the Hg(II)-contacted pyrite residuals were completely rejected by the DE/UF system. Therefore, a membrane filter containing pyrite-Hg(II) could provide another reactive cake layer capable of further removal of Hg(II) without post-chemical treatment for reuse.
Experimental evaluation of tasking and teaming design patterns for human delegation of unmanned vehicles
Authors: Heilemann Felix , Lindner Sebastian , Schulte Axel 
Published: August 2021

AbstractThis work discusses different approaches for the cooperation between humans as a supervisor and multiple unmanned vehicles (UVs). We evaluated the most promising approach experimentally with expert pilots of the German Air Force. The co-agency of humans and highly automated unmanned systems (i.e., human autonomy teaming, HAT) is described by the use of a design and description language for HAT design patterns. This design language is used to differentiate control modes for tasking, teaming, and swarming of UVs. The different control modes are then combined in a planner agent (PA) design pattern that further enables the UV guidance on scalable delegation levels from a single individual up to a team. The desired system behavior and interaction concept of the PA for these scalable delegation levels is then transferred to the domain of manned-unmanned teaming in fighter aircraft missions. To demonstrate the applicability of the system, we implemented the concept into our fast-jet simulator of the Institute of Flight Systems (IFS) and conducted an experimental campaign with expert pilots. The results of the experiment showed (1) task delegation with the PA design pattern is faster and reduces the error potential; (2) scalable delegation levels enable a pilot and situation-specific task delegation; (3) the delegation of teams is faster and reduces the error potential; however, in some situations, deeper access through the scalable delegation levels is needed; (4) the concept is intuitive and the transparency and trust in UVs and swarms were very high; and (5) the pilots could imagine operating such systems in the future. Overall speaking the presented PA design pattern is suited for the guidance of UVs and the scalable delegation levels are beneficial.
Copular clauses in Dene languages: Argument structure and interpretation
Authors: Welch Nicholas , Bouvier White Marie-Louise 
Published: August 2021

AbstractA widely accepted assumption in both the syntactic and semantic literature is that copulas lack semantic content. A consequent question is how to explain the existence in certain languages of two copular verbs that give rise to different interpretations. Such is the case in numerous languages of the Dene family (formerly known as Athapaskan). We explain this situation with the hypothesis that the copulas realize an underlying three-copula system differing in argument structure. Differences between the interpretations of copular clauses in these languages originate in the compositional semantics of these structures, not in any lexical semantic differences.This hypothesis successfully predicts the distributional differences between the surface forms of the Dene copulas, such as their compatibility with adjuncts of time and intentionality, interactions with accusative case, and semanticlifetime effects.
