Black Soldier Fly Diet Impacts Soil Greenhouse Gas Emissions From Frass Applied as Fertilizer

Increased global production of animal-based protein results in high greenhouse gas (GHG) emissions and other adverse consequences for human and planetary health. Recently, commercial insect rearing has been claimed a more sustainable source of animal protein. However, this system also leaves residues called frass, which—depending on the insect diet—is rich in carbon (C) and nitrogen (N), and could thus be used as fertilizer in agriculture. The impact of this kind of fertilizer on soil GHG emissions is yet unknown. Therefore, we investigated the effect of black soldier fly (Hermetia illucens L.) frass derived from a carbohydrate (Carb-) or a protein (Prot-) based diet applied at two different application rates to an arable soil on C and N fluxes and microbial properties in a 40-day incubation experiment. CO2, N2O, NO, N2, CH4, water extractable organic C (WEOC), and inorganic N were continuously measured quantitatively. At the end of the incubation, microbial biomass (MB), stoichiometry, community composition, and abundance of functional genes were assessed. Along with a strong increase in WEOC and CO2, Carb-frass caused strong initial N2O emissions associated with high N and C availability. In contrast, Prot-frass showed lower CO2 emissions and N2O release, although soil nitrate levels were higher. At the end of incubation, MB was significantly increased, which was more pronounced following Carb-frass as compared to Prot-frass application, and at higher amendment rates. Fungal abundance increased most from both frass types with an even stronger response at higher application rates, whereas bacterial abundance rose following Carb-frass as compared to Prot-application. Abundance of functional genes related to ammonia-oxidizing bacteria and archaea were enhanced by high frass application but did not clearly differ between frass types. C use efficiency of microorganisms, as revealed by the metabolic quotient, was most strongly reduced in the high Prot-frass application rate. Overall, insect diet influenced available C and N in frass and thus affected mineralization dynamics, GHG emissions, and microbial growth. Overall, emissions were very high undermining the potential environmental benefit of insect based protein production and calling for more detailed analyses before frass is widely applied in agriculture.
Distortion Approximation of a Compressed Softmax Layer

Deep neural networks need to be compressed due to their high memory requirements and computational complexity. Numerous compression methods have been proposed to solve this issue, but we still do not fully understand how the compression error will impact the neural networks. We take inspiration from the rate distortion theory to propose a new distortion function which measures the gap between the Bayes risk of a classifier before and after the compression. Since this distortion is not tractable, we derive a theoretical closed-form approximation when the last fully connected layer of a deep neural network is compressed with a uniform quantizer. This approximation provides insight into the relationship between the accuracy loss and some key characteristics of the neural network. Numerical simulations show that the approximation is reasonably accurate.
Examining the Type of Legal Representation and Its Influence on Disaggregated Dispositions in Juvenile Court

While prior studies of juvenile court outcomes have examined the impact of legal representation on out-of-home placement versus community sanctions, previous research has not fully explored the variation within sanctions that youth receive. The current study examines the influence of type of legal representation (public defender or private attorney) when predicting juvenile adjudications and dispositions. Using a sample of delinquent referrals from a Northeast state between 2009 and 2014, results showed that youth do receive different outcomes (e.g., probation, drug and alcohol treatment, accountability-oriented dispositions, etc.) based on the type of legal representation. The findings have important implications for juvenile court processing related to how courtroom actors impact case outcomes.
Flexibility and Hydration of Amphiphilic Hyperbranched Arabinogalactan-Protein from Plant Exudate: A Volumetric Perspective

Plant Acacia gum exudates are composed by glycosylated hydroxyproline-rich proteins, which have a high proportion of heavily branched neutral and charged sugars in the polysaccharide moiety. These hyperbranched arabinogalactan-proteins (AGP) display a complexity arising from its composition, architecture, and conformation, but also from its polydispersity and capacity to form supramolecular assemblies. Flexibility and hydration partly determined colloidal and interfacial properties of AGPs. In the present article, these parameters were estimated based on measurements of density and sound velocity and the determination of volumetric parameters, e.g., partial specific volume (vs°) and coefficient of partial specific adiabatic compressibility coefficient (βs°). Measurements were done with Acacia senegal, Acacia seyal, and fractions from the former separated according to their hydrophobicity by Hydrophobic Interaction Chromatography, i.e., HIC-F1, HIC-F2, and HIC-F3. Both gums presented close values of vs° and βs°. However, data on fractions suggested a less hydrated and more flexible structure of HIC-F3, in contrast to a less flexible and more hydrated structure of HIC-F2, and especially HIC-F1. The differences between the macromolecular fractions of A. senegal are significantly related to the fraction composition, protein/polysaccharide ratio, and type of amino acids and sugars, with a polysaccharide moiety mainly contributing to the global hydrophilicity and a protein part mainly contributing to the global hydrophobicity. These properties form the basis of hydration ability and flexibility of hyperbranched AGP from Acacia gums.
Chlamydomonas ATX1 is essential for Cu distribution towards the secretory pathway and maintenance of biomass in conditions demanding cupro-enzyme dependent metabolic pathways

Copper (Cu) chaperones, of which yeast ATX1 is a prototype, are small proteins with a Cu(I) binding Mx-CxxC motif, and are responsible for directing intracellular Cu towards specific client protein targets that use Cu as a cofactor. The Chlamydomonas reinhardtii ATX1 (CrATX1) was identified because of its high sequence similarity with yeast ATX1. Like the yeast homologue, CrATX1 accumulates in iron-deficient cells (but is not impacted by other metal-deficiencies), and YFP-ATX1 is distributed in the cytoplasm. Reverse genetic analysis using artificial microRNA (amiRNA) to generate lines with reduced CrATX1 abundance and CRISPR/CPF1 to generate ATX1 knock out lines validated a function for ATX1 in iron-poor cells, most likely because of an impact on metalation of the multicopper oxidase FOX1, which is an important component in high-affinity iron uptake. A more general impact on the secretory pathway is indicated by reduced growth of ATX1 mutant lines on guanine as a sole nitrogen source, which we attribute to loss of function of UOX1, a urate oxidase involved in guanine assimilation. The block of Cu trafficking towards the secretory pathway in ATX1 mutants is strikingly evident by a reduced amount of intracellular Cu in all conditions probed in this work.
Transcriptome Analysis of Melocactus glaucescens (Cactaceae) Reveals Metabolic Changes During in vitro Shoot Organogenesis Induction

Melocactus glaucescens is an endangered cactus highly valued for its ornamental properties. In vitro shoot production of this species provides a sustainable alternative to overharvesting from the wild; however, its propagation could be improved if the genetic regulation underlying its developmental processes were known. The present study generated de novo transcriptome data, describing in vitro shoot organogenesis induction in M. glaucescens. Total RNA was extracted from explants before (control) and after shoot organogenesis induction (treated). A total of 14,478 unigenes (average length, 520 bases) were obtained using Illumina HiSeq 3000 (Illumina Inc., San Diego, CA, USA) sequencing and transcriptome assembly. Filtering for differential expression yielded 2,058 unigenes. Pairwise comparison of treated vs. control genes revealed that 1,241 (60.3%) unigenes exhibited no significant change, 226 (11%) were downregulated, and 591 (28.7%) were upregulated. Based on database analysis, more transcription factor families and unigenes appeared to be upregulated in the treated samples than in controls. Expression of WOUND INDUCED DEDIFFERENTIATION 1 (WIND1) and CALMODULIN (CaM) genes, both of which were upregulated in treated samples, was further validated by real-time quantitative PCR (RT-qPCR). Differences in gene expression patterns between control and treated samples indicate substantial changes in the primary and secondary metabolism of M. glaucescens after the induction of shoot organogenesis. These results help to clarify the molecular genetics and functional genomic aspects underlying propagation in the Cactaceae family.
Detection of Subclinical Paroxysmal Atrial Fibrillation and Its Correlation with Candidate Genes in Patients with Cryptogenic Ischemic Stroke and TIA

Abstract Introduction: Cardioembolic etiology is assumed to be the most frequent cause of cryptogenic strokes. The detection of subclinical paroxysmal atrial fibrillation (AF) is important in the correct choice of preventive treatment. The aim of this prospective study was to detect the incidence of AF in patients with a cryptogenic stroke or transient ischemic attack (TIA) and to evaluate the association between the presence of AF and selected single-nucleotide polymorphisms (SNP). Methods: Patients with a cryptogenic stroke/ TIA (n=100) and a control group (n=15) of volunteers without significant cardiovascular disease were included in the study during the period of 2014 to 2019. To detect AF they underwent 12 months of ECG monitoring using an implanted loop recorder (ILR). Genotyping for SNPs rs10033464, rs2200733, rs225132, and rs2106261 was performed by a high resolution melting analysis. Results: We found AF to be present in 24 (24%) patients with a cryptogenic stroke/TIA, versus no subjects in the control group. The SNPs rs2106261, rs2200733, rs225132, and rs10033464 were not found to be associated with AF in our study (p=0.240; 1.000; 0.887; 0.589). However, a weak trend for a higher frequency of rs2106261 risk allele A homozygotes was observed in the patients with AF compared to the patients without AF (0.416 vs. 0.263, p=0.073). Homozygotes for allele A of rs2106261 were also present in a significantly higher frequency in AF patients compared to the controls (0.416 vs. 0.133, p = 0.012). Conclusion: In our study paroxysmal AF was a probable etiological factor in 24% of patients with cryptogenic ischemic stroke / TIA during the 12 months of monitoring. The homozygous allele A of rs2106261 was identified to be the possible genetic risk factor of AF, but this should be verified in larger cohorts. The study has been registered at www.clinicaltrials. gov, identifier NCT02216370.
Deriving Mental Energy From Task Completion

Many tasks in everyday life (e.g., making an accurate decision, completing job tasks, and searching for product information) are extrinsically motivated (i.e., the task is performed to gain a benefit) and require mental effort. Prior research shows that the cognitive resources needed to perform an extrinsically motivated task are allocated pre-task. The pre-task allocation of mental resources tends to be conservative, because mental effort is costly. Consequently, there are mental energy deficits when the use of mental resources exceeds the allocated amount. This research provides evidence for post-task mental energy replenishment. The amount of resource replenishment is a function of the size of the mental energy deficit and the favorability of the cost-benefit trade-off experienced at the completion of the task (i.e., the value of the reward given the energy investment). The findings have implications for how cognitive resources management influences the availability of mental energy on a moment-to-moment basis.
Associations Between Air Pollution Exposure and Daily Pediatric Outpatient Visits for Dry Eye Disease: A Time-Series Study in Shenzhen, China

Objectives: This study aimed to investigate the associations between air pollution exposure and pediatric outpatient visits for dry eye disease (DED) in Shenzhen, China. Methods: Generalized additive models were utilized to explore the acute effects of air pollution exposure on pediatric outpatient visits for DED. Results: Single-day lag exposures to NO2, O3, PM2.5, and PM10 were associated with DED outpatient visits at lag days 0, 6, 4 and 2. Relative risks (RRs) for DED given a 10-μg/m3 increase in NO2, O3, PM2.5, and PM10 concentrations were 1.062[95% confidence interval (CI) 1.003, 1.123], 1.015(95% CI 1.001, 1.031), 1.052(95% CI 1.001, 1.115), and 1.038 (95% CI 1.002, 1.076), respectively. RR for DED given a 10-μg/m3 increase in NO2 over cumulative lag days 0–1 was 1.075 (95% CI 1.009, 1.147), and RR for DED given a 10-μg/m3 increase in PM10 over cumulative lag days 0–4 was 1.051 (95% CI 1.003, 1.102). Conclusion: The observed associations between air pollution and outpatient visits for DED may provide evidence for policy makers to consider implementing measures to reduce the risk of DED owing to air pollution in China.
Regulation of membrane scission in yeast endocytosis

During clathrin-mediated endocytosis, a flat plasma membrane is shaped into an invagination that undergoes scission to form a vesicle. In mammalian cells, the force that drives the transition from invagination to vesicle is primarily provided by the GTPase dynamin that acts in concert with crescent-shaped BAR domain proteins. In yeast cells, the mechanism of endocytic scission is unclear. The yeast BAR domain protein complex Rvs161/167 (Rvs) nevertheless plays an important role in this process: deletion of Rvs dramatically reduces scission efficiency. A mechanistic understanding of the influence of Rvs on scission however, remains incomplete. We used quantitative live-cell imaging and genetic manipulation to understand the recruitment and function of Rvs and other late-stage proteins at yeast endocytic sites. We found that arrival of Rvs at endocytic sites is timed by interaction of its BAR domain with specific membrane curvature. A second domain of Rvs167- the SH3 domain-affects localization efficiency of Rvs. We show that Myo3, one of the two type-I myosins in Saccharomyces cerevisiae, has a role in recruiting Rvs167 via the SH3 domain. Removal of the SH3 domain also affects assembly and disassembly of actin and impedes membrane invagination. Our results indicate that both BAR and SH3 domains are important for the role of Rvs as a regulator of scission. We tested other proteins implicated in vesicle formation in Saccharomyces cerevisiae, and found that neither synaptojanins nor dynamin contribute directly to membrane scission. We propose that recruitment of Rvs BAR domains delays scission and allows invaginations to grow by stabilizing them. We also propose that vesicle formation is dependent on the force exerted by the actin network component of the endocytic machinery.
Factual knowledge of students about plants is associated with attitudes and interest in botany

ABSTRACT Plants are crucial parts of ecosystems but are traditionally considered boring and difficult by students. It is therefore not clear whether factual knowledge about plants contributes to building positive attitudes and interest in botany. We investigated whether factual knowledge about monocotyledonous plants is associated with secondary students’ attitudes toward and interest in plants. Furthermore, we examined whether self-reported plant cultivation experiences and gender differences exist in attitudes toward plants. Factual knowledge about monocotyledonous plants significantly correlated with attitudes toward plants and these attitudes were greatly influenced by interest in botany, ecology, evolution, and zoology, but not with other, more distant biological disciplines (e.g. microbiology, or health and nutrition). Females received better scores in knowledge and attitudes toward plants, but interest in plants was similar between males and females. We suggest that (1) factual knowledge in botany is essential in building positive attitudes toward plants and that (2) inter-connections between botany with zoology, ecology and evolution may help with elimination of plant blindness and building positive attitudes toward plants.
Transient thermal design for athermal bond-line estimates

Transient operating temperatures often allow a lens cell to expand before the lens itself, potentially leading to stresses well in excess of the lens tensile strength. The transients thus affect the calculation of the athermal bond-line thickness, estimates of which have historically been based on thermal equilibrium conditions. In this paper, we present both analytical expressions and finite-element modeling results for thermal-transient bond-line design. Our results show that a cell with a large CTE and a bond thickness based on thermal transients is the best strategy for reducing the tensile stress on the bonded lens over a range of operating temperatures.
Electric Field Induced Polarization Effects Measured by In Situ Neutron Spectroscopy

Despite the success of electrical stimulation in many areas, including clay or sludge dewatering, extraction of juices from fruit pulp, fracture healing and targeted drug delivery, the induced transport mechanisms are controlled by unknown factors. While electroosmotic dewatering of clays particles <10 μm is well known, understanding of how tightly bound water molecules are removed from within the clay interlayers is still incomplete. By performing quasielastic neutron scattering experiments with in-situ electric field stimuli on calcium montmorillonite (Ca-Mt) pre-hydrated at relative humidity (RH) of 58 and 85%, we observed an increase in the water mean residence time, suggesting that hydrogen bonding lifetimes are prolonged under electric field. Assuming that at these RH most all water present resides within the interlayer space of the Ca-Mt, this result indicates strong polarization of the water by the interlayer cation. This electroosmotic induced reorganization has important implications in terms of.

Horizontal transfer of a conserved npc-2 like effector gene in rust fungi that suppresses cell death in plants

ML/MD-2 is a conserved lipid/sterol-binding protein family having a role in sterol transfer and innate immunity in lower and higher eukaryotes. Here we report a genome-wide survey of this family, identifying 84 genes in 25 fungal and five oomycetes plant pathogen, having a different nutrition mode. All the fungal species were found to have varied numbers of family members, a distinctively substantial expansion of the ML gene family was observed in Rhizophagus irregularis (RI) with 33 genes. Our analysis also showed that NPC2 like proteins, a subfamily of ML domain superfamily, were not only restricted to animals and insect species but also present in plant fungal pathogens, including members of Clavicipitaceae, Pucciniacease, and Tremellaceae family. The phylogenetic analysis showed that these NPC2 like fungal proteins are more closely related to animals/insects than other fungal species. The molecular docking studies of these proteins with cholesterol and other derivatives indicate lipid-binding functional conservation across the animal and fungi kingdom. Further, the full length CDS of one of the npc2 like genes from Puccinia triticina (Pt5643) was PCR amplified and further characterized using various studies such as qRT-PCR, expression in onion epidermal cells, Nicotiana benthamiana for subcellular localization studies, yeast functional complementation, and expression studies. The mRNA abundance of Pt5643 was observed to be increased along with the infection progression and exhibits the highest expression at 5thday post-infection (dpi), suggesting its important role in the P. triticina infection cycle in wheat. The fluorescent confocal microscopy of transiently expressed YFP tagged Pt5643 in onion epidermal cells and N. benthamiana shows its location in cytoplasm and nucleus, indicating its involvement in the manipulation of host genes. The functional complementation of Pt5643 in npc2 mutant yeast showed its functional similarity to the eukaryotic npc2 gene. Further, the overexpression of Pt5643 also suppressed the BAX and H2O2 induced program cell death in N. benthamiana and yeast, respectively thus proving to be a novel horizontally transferred effector in rust fungal pathogens. Altogether the present study reports the novel function of fungal NPC2 like proteins playing a crucial role in host defense manipulation possibly through lipid binding/transport similar to animals.
