description: MicroRNAs (miRNAs) play key regulatory roles in various biological processes and diseases. A comprehensive analysis of large scale small RNA sequencing data (smRNA-seq) will be very helpful to explore tissue or disease specific miRNA markers and uncover miRNA variants. Here, we systematically analyzed 410 human smRNA-seq datasets, which samples are from 24 tissue/disease/cell lines. We tested the mapping strategies and found that it was necessary to make multiple-round mappings with different mismatch parameters. miRNA expression profiles revealed that on average ∼70% of known miRNAs were expressed at low level or not expressed (RPM < 1) in a sample and only ∼9% of known miRNAs were relatively highly expressed (RPM > 100). About 30% known miRNAs were not expressed in all of our used samples. The miRNA expression profiles were compiled into an online database (HMED, http://bioinfo.life.hust.edu.cn/smallRNA/). Dozens of tissue/disease specific miRNAs, disease/control dysregulated miRNAs and miRNAs with arm switching events were discovered. Further, we identified some highly confident editing sites including 24 A-to-I sites and 23 C-to-U sites. About half of them were widespread miRNA editing sites in different tissues. We characterized that the 2 types of editing sites have different features with regard to location, editing level and frequency. Our analyses for expression profiles, specific miRNA markers, arm switching, and editing sites, may provide valuable information for further studies of miRNA function and biomarker finding.

description: The development of a database for making model species assignments when preparing total organic gas (TOG) emissions input for atmospheric models is described. This database currently has assignments of model species for 12 different gas-phase chemical mechanisms for over 1700 chemical compounds and covers over 3000 chemical categories used in five different anthropogenic TOG profile databases or output by two different biogenic emissions models. This involved developing a unified chemical classification system, assigning compounds to mixtures, assigning model species for the mechanisms to the compounds, and making assignments for unknown, unassigned, and nonvolatile mass. The comprehensiveness of the assignments, the contributions of various types of speciation categories to current profile and total emissions data, inconsistencies with existing undocumented model species assignments, and remaining speciation issues and areas of needed work are also discussed. The use of the system to prepare input for SMOKE, the Speciation Tool, and for biogenic models is described in the supplementary materials. The database, associated programs and files, and a users manual are available online at http://www.cert.ucr.edu/~carter/emitdb.Implications: Assigning air quality model species to the hundreds of emitted chemicals is a necessary link between emissions data and modeling effects of emissions on air quality. This is not easy and makes it difficult to implement new and more chemically detailed mechanisms in models. If done incorrectly, it is similar to errors in emissions speciation or the chemical mechanism used. Nevertheless, making such assignments is often an afterthought in chemical mechanism development and emissions processing, and existing assignments are usually undocumented and have errors and inconsistencies. This work is designed to address some of these problems.

Functional analysis of the SseK family of Salmonella SPI‐2 type III secretion system effectors
Creators: name: Günster, Regina Agnes
Publisher: name: Imperial College London
Year: 2017

description: In humans, serovars of Salmonella enterica cause diseases ranging from gastroenteritis to systemic typhoid fever. Salmonella encodes numerous translocated virulence (effector) proteins that enable the bacterium’s complex intracellular lifestyle. Three poorly characterised Salmonella effectors are the SseK proteins: SseK1, SseK2 and SseK3. This work showed that all three effectors are translocated by the SPI‐2 type III secretion system into macrophages. Despite high amino acid similarity between the proteins, SseK1 is cytosolic and SseK2 and SseK3 associate with the Golgi network. When ectopically expressed in mammalian cells, SseK1, SseK2 and SseK3 suppressed NF‐κB pathway activation. This inhibition was specific for TNFα‐induced signaling but not TLR4‐, or interleukin‐induced NF‐κB pathway activation. After physiological delivery of the effectors into macrophages during Salmonella infection, SseK1 and SseK3 inhibited NF‐ κB activity in an additive manner and suppressed TNFα‐induced necroptotic host cell death. Despite stable interaction between SseK3 and the E3‐ubiquitin ligase TRIM32 in macrophages, SseK3‐mediated inhibition of NF‐κB activation and host cell death did not require TRIM32. In addition, bacterial burden in Trim32‐/‐ mice were indistinguishable from wild‐type mice after short‐term infection with Salmonella. Catalytic activity of the SseK effectors required a DxD motif, which in SseK1 and SseK3 is essential for arginine‐N‐acetylglucosamine (GlcNAc)‐ ylation of target proteins. In infected macrophages, SseK1 and SseK3 caused arginine‐ GlcNAcylation of a diverse range of distinct bacterial and host proteins, including auto‐ GlcNAcylation of SseK1 and SseK3. Both SseK1 and SseK3 induced arginine‐GlcNAcylation of TRADD, which is most likely the cause of the effector’s inhibitory effect on both NF‐κB activation and host cell death. In addition, a large number of Golgi network associated proteins were identified as potential SseK3 GlcNAcylation targets. This suggests additional, yet‐to‐be validated functions of the effectors during Salmonella infection besides inhibition of NF‐κB signalling and necroptosis in macrophages.

description: Machine Translation is a mature technology for many high-resource language pairs. However in the context of low-resource languages, there is a paucity of parallel data datasets available for developing translation models. Furthermore, the development of datasets for low-resource languages often focuses on simply creating the largest possible dataset for generic translation. The benefits and development of smaller in-domain datasets can easily be overlooked. To assess the merits of using in-domain data, a dataset for the specific domain of health was developed for the low-resource English to Irish language pair. Our study outlines the process used in developing the corpus and empirically demonstrates the benefits of using an in-domain dataset for the health domain. In the context of translating health-related data, models developed using the gaHealth corpus demonstrated a maximum BLEU score improvement of 22.2 points (40%) when compared with top performing models from the LoResMT2021 Shared Task. Furthermore, we define linguistic guidelines for developing gaHealth, the first bilingual corpus of health data for the Irish language, which we hope will be of use to other creators of low-resource data sets. gaHealth is now freely available online and is ready to be explored for further research.

Biochar as a carbon sequestering construction material in cementitious mortar

Publisher: name: Academic Journal of Civil Engineering
Year: 2017

description: Recent efforts to attain carbon negative construction practices in Singapore and other developed countries leads to a search for construction materials that can reduce net carbon emission associated with concrete constructions. One such material is biochar which can sequester fixed carbon in its structure. Therefore, using biochar as a mixed-in component in cementitious material can reduce the net greenhouse emission associated with concrete constructions. Our study focuses on application of biochar derived from mixed-wood saw dust as a cement replacement in mortar. Experimental findings suggest that, due to its fine particle size and microfiller effect, up to 4% cement replacement by biochar yielded slight improvement in compressive strength while reducing sorptivity by about 70% after 28 days. Improvement in strength and permeability of mortar by incorporating biochar suggest that it can be successfully deployed as a carbon sequestering concrete construction material. Durable and strong infrastructure means reduced vulnerability to damage and thus need for subsequent repairs over its service lifespan. This will help contribute toward economic and environmental sustainability of buildings.

description: We report for the first time the green synthesis of silver nanoparticles using West Indian cherry (Malpighia emarginata) extract known for its high vitamin C content. UV–visible spectroscopy, powder X ray diffraction (PXRD), dynamic light scattering (DLS), scanning electron microscopy (SEM) and energy dispersive X ray spectroscopy (EDX) analysis were used to characterise silver nanoparticles. Silver nanoparticles thus synthesised exhibit antimicrobial activity against gram-negative bacteria such as Pseudomonas aeruginosa, Escherichia coli, and gram-positive bacteria such as Bacillus subtilis and Staphylococcus aureus. The antimicrobial property of nanoparticles thus synthesised was applied in the production of silver-activated charcoal nanocomposite towards fabrication of antimicrobial water filtration columns. The microbial filtration efficiency of the nanocomposite was found to be higher compared to virgin activated charcoal even with reusage.

Predicting cutaneous and visceral leishmaniasis outbreak occurrence in Brazil: A machine learning model of forest cover, climate, and land use

description: Cutaneous and visceral leishmaniasis (CL and VL) are neglected vector-borne diseases of growing concern in Brazil, where deforestation, reforestation, and urban expansion are reshaping vector habitats and disease risk. While previous research has identified forest cover as a primary environmental predictor of CL, the effects of dynamic forest variables—particularly reforestation—remain under explored. Our analyses aim to address the central question: whether environmental factors can help predict occurrence of leishmaniasis in Brazil. Here, we apply machine learning-based models to test how climate, land-use, and forest change variables influence outbreak occurrence of CL and VL across Brazil’s Amazon from 2001 to 2018. Using Extreme Gradient Boosting (XGBoost) with Bayesian optimization and spatial subsetting, we leveraged over a decade of municipality-level case data and high-resolution geospatial covariates to assess variable importance and characterize nonlinear relationships via partial dependence plots. As for the precision of our CL model, we found that out-of-sample area-under-the-curve (AUC) was 0.770, and for VL, our model’s out of sample AUC was 0.729. 

We found that, in line with previous ecological work, forest cover was a strong predictor of CL outbreak occurrence but weak for VL. Contrary to expectations, deforestation was positively associated with CL risk, while reforestation was negatively associated—suggesting that habitat disruption may increase CL transmission through human-vector contact. For VL, forest-related variables exhibited hump-shaped or declining effects, highlighting complex, potentially nonlinear interactions between land use and synanthropic vector ecology. Temperature, urban cover, and population also emerged as important predictors for both diseases. Our results support the ecological relevance of land-use change in shaping leishmaniasis risk and introduce reforestation as a novel covariate with differential predictive effects across disease types. These findings underscore the value of machine learning in disentangling high-dimensional, nonlinear disease-environment relationships and call for further integration of ecological, vector, and host data in predictive modeling of leishmaniasis under ongoing landscape transformation.

description: Petroleum refineries produce large amount of wastewaters, which often contain a wide range of different compounds. Some of these constituents may be recalcitrant and therefore difficult to be treated biologically. This study evaluated the capability of an aerobic submerged fixed-bed reactor (ASFBR) containing a corrugated PVC support material for biofilm attachment to treat a complex and high-strength organic wastewater coming from a petroleum refinery. The reactor operation was divided into five experimental runs which lasted more than 250 days. During the reactor operation, the applied volumetric organic load was varied within the range of 0.5–2.4 kgCOD.m−3.d−1. Despite the inherent fluctuations on the characteristics of the complex wastewater and the slight decrease in the reactor performance when the influent organic load was increased, the ASFBR showed good stability and allowed to reach chemical oxygen demand, dissolved organic carbon and total suspended solids removals up to 91%, 90% and 92%, respectively. Appreciable ammonium removal was obtained (around 90%). Some challenging aspects of reactor operation such as biofilm quantification and important biofilm constituents (e.g. polysaccharides (PS) and proteins (PT)) were also addressed in this work. Average PS/volatile attached solids (VAS) and PT/VAS ratios were around 6% and 50%, respectively. The support material promoted biofilm attachment without appreciable loss of solids and allowed long-term operation without clogging. Microscopic observations of the microbial community revealed great diversity of higher organisms, such as protozoa and rotifers, suggesting that toxic compounds found in the wastewater were possibly removed in the biofilm.

description: A generalized linear modeling framework to the analysis of responses and response times is outlined. In this framework, referred to as bivariate generalized linear item response theory (B-GLIRT), separate generalized linear measurement models are specified for the responses and the response times that are subsequently linked by cross-relations. The cross-relations can take various forms. Here, we focus on cross-relations with a linear or interaction term for ability tests, and cross-relations with a curvilinear term for personality tests. In addition, we discuss how popular existing models from the psychometric literature are special cases in the B-GLIRT framework depending on restrictions in the cross-relation. This allows us to compare existing models conceptually and empirically. We discuss various extensions of the traditional models motivated by practical problems. We also illustrate the applicability of our approach using various real data examples, including data on personality and cognitive ability.
Biochar as a bond enhancement in fiber-reinforced mortar

Publisher: name: Academic Journal of Civil Engineering
Year: 2017

description: This study focuses on the evaluation of using biochar to enhance the strength performance of cement mortar reinforced with polypropylene (PP) fibers. Biochar was produced with mixed wood sawdust that was discarded from a local sawmill. It was then divided into two groups, with one group being subjected to dosage of carbon dioxide until it reached saturation. Results showed that when reinforcing PP fibers are coated with CO2-dosed biochar, the cement mortar experienced a 13% and 16% reduction in compressive and flexural strength respectively. However, fibers that were not saturated with CO2 recorded improvement of about 19% for both compressive and flexural strength respectively over control samples containing PP fibers not coated with biochar. Coating of biochar on the fibers also reduced sorptivity significantly compared to control samples which means that the permeability of mortar would be lower if biochar is used to coat PP fibers. This phenomenon can be explained by the micro-filler effects afforded by the biochar particles, which serves to strengthen the bond between the surface of the PP fibers with the mortar matrix. These results highlight the potential usefulness of biochar as a sustainable carbon sink that can also be used as a bond and strength enhancement for cement mortar.

description: The textile industry is highly water intensive and one of the major contributor in environment pollution
especially water in Bangladesh. In general, the results show that the use of the low impact reactive dyes has
greater ecological advantages as it reduces the COD, BOD, TDS, TSS, and increase the DO and balanced pH
values of the effluent considerably. Further, the fabric made from organic cotton itself also reduces the COD,
BOD, TSS and TDS values. Besides, significantly increases the DO values maintaining tolerable pH values of
the effluents. Finally it can be concluded that if various verified eco-friendly dyes and chemicals are used
widely in wet processing, the environment pollution could be minimized to a greater extent.

This application is built upon the widely-adopted OpenNMT ecosystem, and is particularly useful for new entrants to the field, as it simplifies the setup of the development environment and creation of train, validation, and test splits. The application offers a graphing feature that illustrates the progress of model training, and employs SentencePiece for creating subword segmentation models. Furthermore, the application provides an intuitive user interface that facilitates hyperparameter customization. Notably, a single-click model development approach has been implemented, and models developed by adaptNMT can be evaluated using a range of metrics. To encourage eco-friendly research, adaptNMT incorporates a green report that flags the power consumption and kgCO${_2}$ emissions generated during model development. The application is freely available.

description: Biochar has recently been explored as an alternate construction material. While it has been deployed as road construction, there is an emerging trend of using biochar as concrete admixture and other non-structural building elements. This study explores the use of biochar as a component in wall plaster and pellets that are used to fill cavities for interior non-structural wall panels. Biochar was incorporated in plastering material and the carbon dioxide adsorption capability of this material mix was compared to that of control samples (made up of pure plaster). It was found that biochar increased the net carbon dioxide adsorption capability by more than four times. However, contrary to claims in the literature, we found no evidence that the biochar in this mixture can significantly remove total volatile organic compounds from the indoor air. In a separate study, biochar was used to coat pellets that were used to fill cavities in cavity wall. The biochar was found to increase the net carbon dioxide adsorption capability by about six times (compared to control samples, which were plaster pellets without biochar coating). There was also no significant adsorption of total volatile organic compounds. These results indicated clearly that biochar can be effective as a regulating agent for indoor carbon dioxide level, which is one of the main determinant factors for the infamous Sick Building Syndrome.

description: Graduates with well-developed capabilities in finance are invaluable to our society and in increasing demand. Universities face the challenge of designing finance programmes to develop these capabilities and the essential knowledge that underpins them. Our research responds to this challenge by identifying threshold concepts that are central to the mastery of finance and by exploring their potential for informing curriculum design and pedagogical practices to improve student outcomes. In this paper, we report the results of an online survey of finance academics at multiple institutions in Australia, Canada, New Zealand, South Africa and the United Kingdom. The outcomes of our research are recommendations for threshold concepts in finance endorsed by quantitative evidence, as well as a model of the finance curriculum incorporating finance, modelling and statistics threshold concepts. In addition, we draw conclusions about the application of threshold concept theory supported by both quantitative and qualitative evidence. Our methodology and findings have general relevance to the application of threshold concept theory as a means to investigate and inform curriculum design and delivery in higher education.

description: Gansus yumenensis Hou and Liu, 1984 is a basal ornithuromorph bird that has been recovered from the Lower Cretaceous Xiagou Formation in the Changma Basin of Gansu Province in northwestern China. Although it bears important significance in understanding the origin and early evolution of Ornithuromorpha, this taxon has only received preliminary morphological study. Here, we provide a detailed description of the postcranial morphology of Gansus yumenensis based on seven new specimens and new data from previously reported specimens, and update diagnosis for this taxon. Our phylogenetic analysis including new morphological data on Gansusyumenensis resolves all known four genera of Changma ornithuromorphs as more derived taxa than Jehol members of this clade, indicating the difference between Changma and Jehol avifauna.

description: The global mixed-integer quadratic optimizer, GloMIQO, addresses mixed-integer quadratically constrained quadratic programs (MIQCQP) to ε-global optimality. This paper documents the branch-and-cut framework integrated into GloMIQO 2. Cutting planes are derived from reformulation–linearization technique equations, convex multivariable terms, αBB convexifications, and low- and high-dimensional edge-concave aggregations. Cuts are based on both individual equations and collections of nonlinear terms in MIQCQP. Novel contributions of this paper include: development of a corollary to Crama's [Concave extensions for nonlinear 0-1 maximization problems, Math. Program. 61 (1993), pp. 53–60] necessary and sufficient condition for the existence of a cut dominating the termwise relaxation of a bilinear expression; algorithmic descriptions for deriving each class of cut; presentation of a branch-and-cut framework integrating the cuts. Computational results are presented along with comparison of the GloMIQO 2 performance to several state-of-the-art solvers.

description: The objectives of this study were to chemically characterise and evaluate the antioxidant potential of the essential oil from Teucrium flavum L. subsp. flavum growing spontaneously in Tunisia. The volatile oil was extracted by hydrodistillation of the aerial parts in a Clevenger type apparatus. Forty constituents were identified via GC and GC-MS analysis. β-caryophyllene (32.5%) and α-humulene (17.8%) were the most abundant components. The evaluation of free radical scavenging activity using stable DPPH free radical showed that the volatile oil exhibits a moderate antioxidant activity and reduces DPPH to 50% at EC50 value of 1230 μg mL− 1.

description: In this study, we focused on the in vitro anti-metastatic effects of deoxyelephantopin (DOE), a sesquiterpene lactone from Elephantopus scaber on lung cancer A549 cells. DOE significantly decreased the metastatic potential of A549 cells as demonstrated by transwell invasion and migration assay. DOE inhibited the expression of matrix metalloproteinase-2 (MMP-2), MMP-9, urokinase-type plasminogen activator and urokinase-type plasminogen activator receptor at transcript level. Tissue inhibitors of metalloproteinase-2 (TIMP-2) mRNA levels was up-regulated in A549 tumour cells without any change in TIMP-1 expression after DOE treatment. DOE inhibited the protein levels of p-ERK1/2 and p-Akt in A549 cells but it activated p-JNK, p-p38 protein expression. NF-κB and IκBα expressions were down-regulated in DOE-treated cells. All these results demonstrated that DOE has shown anti-metastatic activity against A549 tumour cells.
