Divided Alliances: A Discussion of Inuit Resilience in Post-Secondary Education
Authors: Snow Kathy , Obed Diane , Lane Jodie
Published: September 2024

Although the Inuit high school completion rate has been climbing, the same cannot be said for Inuit participation in post-secondary education in Canada. This paper seeks to move beyond the obvious physical, and financial barriers to explore the colonial biases present in post-secondary institutions as further and more enduring challenges to access for Inuit. Through conversations with 10 Inuit post-secondary participants, graduates, and leavers, seven critical factors emerged. Viewed from the perspective of Inuit Qaujimajatuqangit, these factors identified where institutions have continued to fail students. The hope here is to raise greater awareness of the unparalleled challenges Inuit must face when choosing to participate in post-secondary education not only in terms of leaving home, but also of negotiating culture and the worldviews of Southern colonial learning institutions.
Towards an Indigenous Hydropoetics: Human-River Interdependencies in Aboriginal Australian Poetry
Authors: Ryan John Charles
Published: September 2024

This article delineates the idea of an Indigenous hydropoetics as an ancestral outlook on rivers grounded in Aboriginal cultural traditions of, and everyday interactions with, rivers. In particular, two features—embodiment and relationality—prove integral to conceptualising Indigenous hydropoetics in response to the hydrological precarities of the present. Recognising rivers' capacity for agency, the idea is developed in relation to contemporary Aboriginal Australian poetry narrating long-standing human interdependencies with rivers. The hydropoetic verse of Jack Davis, Samuel Wagan Watson, and Jeanine Leane reveals embodied relations to—and relational epistemologies of—rivers and their habitats through a focus on Derbal Yerrigan (the Swan River) of Western Australia, Marrambidya Bila (the Murrumbidgee River) of New South Wales, and Maiwar (the Brisbane River) of Queensland, respectively. Their writing integrates Dreaming narratives and elicits river poiesis, while also confronting aquatic conservation urgencies in Australia. Evoking sacred rivers whose origins lie in the Dreaming, their work also presents a medium for reverent listening to the fluvial world. While Leane’s hydropoetics centres on the mediating role of memory—hers and the river’s—Watson’s poetry calls attention to fractured river ecologies in Brisbane's urban environment. For Davis, bodily relationality between humans, plants, and rivers presents a potent means of ecopolitical resistance through multispecies solidarity. Immersed in Aboriginal creation narratives, an Indigenous hydropoetics foregrounds the multidimensional intersections between humans, rivers, and all life, thus energising new imaginings of rivers and encouraging receptivity to their biocultural complexities.
Two-way Dispatched function in Sonic hedgehog shedding and transfer to high-density lipoproteins
Authors: Ehring Kristina , Ehlers Sophia Friederike , Froese Jurij , Gude Fabian , Puschmann Janna , Grobe Kay
Published: September 2024

The Sonic hedgehog (Shh) signaling pathway controls embryonic development and tissue homeostasis after birth. This requires regulated solubilization of dual-lipidated, firmly plasma membrane-associated Shh precursors from producing cells. Although it is firmly established that the resistance-nodulation-division transporter Dispatched (Disp) drives this process, it is less clear how lipidated Shh solubilization from the plasma membrane is achieved. We have previously shown that Disp promotes proteolytic solubilization of Shh from its lipidated terminal peptide anchors. This process, termed shedding, converts tightly membrane-associated hydrophobic Shh precursors into delipidated soluble proteins. We show here that Disp-mediated Shh shedding is modulated by a serum factor that we identify as high-density lipoprotein (HDL). In addition to serving as a soluble sink for free membrane cholesterol, HDLs also accept the cholesterol-modified Shh peptide from Disp. The cholesteroylated Shh peptide is necessary and sufficient for Disp-mediated transfer because artificially cholesteroylated mCherry associates with HDL in a Disp-dependent manner, whereas an N-palmitoylated Shh variant lacking C-cholesterol does not. Disp-mediated Shh transfer to HDL is completed by proteolytic processing of the palmitoylated N-terminal membrane anchor. In contrast to dual-processed soluble Shh with moderate bioactivity, HDL-associated N-processed Shh is highly bioactive. We propose that the purpose of generating different soluble forms of Shh from the dual-lipidated precursor is to tune cellular responses in a tissue-type and time-specific manner.
A variant-informed decision support system for tackling COVID-19: a transfer learning and multi-attribute decision-making approach
Authors: Salehi Amiri Amirreza , Babaei Ardavan , Simic Vladimir , Tirkolaee Erfan Babaee
Published: September 2024

The global impact of the COVID-19 pandemic, characterized by its extensive societal, economic, and environmental challenges, escalated with the emergence of variants of concern (VOCs) in 2020. Governments, grappling with the unpredictable evolution of VOCs, faced the need for agile decision support systems to safeguard nations effectively. This article introduces the Variant-Informed Decision Support System (VIDSS), designed to dynamically adapt to each variant of concern’s unique characteristics. Utilizing multi-attribute decision-making (MADM) techniques, VIDSS assesses a country’s performance by considering improvements relative to its past state and comparing it with others. The study incorporates transfer learning, leveraging insights from forecast models of previous VOCs to enhance predictions for future variants. This proactive approach harnesses historical data, contributing to more accurate forecasting amid evolving COVID-19 challenges. Results reveal that the VIDSS framework, through rigorous K-fold cross-validation, achieves robust predictive accuracy, with neural network models significantly benefiting from transfer learning. The proposed hybrid MADM approach integrated approaches yield insightful scores for each country, highlighting positive and negative criteria influencing COVID-19 spread. Additionally, feature importance, illustrated through SHAP plots, varies across variants, underscoring the evolving nature of the pandemic. Notably, vaccination rates, intensive care unit (ICU) patient numbers, and weekly hospital admissions consistently emerge as critical features, guiding effective pandemic responses. These findings demonstrate that leveraging past VOC data significantly improves future variant predictions, offering valuable insights for policymakers to optimize strategies and allocate resources effectively. VIDSS thus stands as a pivotal tool in navigating the complexities of COVID-19, providing dynamic, data-driven decision support in a continually evolving landscape.
The effect of electrical muscle stimulation on intentional binding and explicit sense of agency
Authors: Nagai Miwa , Matsui Kazuhiro , Atsuumi Keita , Taniguchi Kazuhiro , Hirai Hiroaki , Nishikawa Atsushi
Published: September 2024

The motivating question for this study is determining whether electrical muscle stimulation (EMS)-induced movements can extend the user’s ability without reducing the sense of agency. Moreover, it is crucial to find the timing of the EMS application that is robust against individual differences and environmental changes. Previous studies have reported that the user-specific EMS-application timings, determined through explicit measures of sense of agency, would effectively shorten their reaction time in a push task while maintaining their sense of agency. However, no study has investigated EMS-application timings in relation to implicit measures of sense of agency. Intentional binding, an example of an implicit measure, refers to the phenomenon whereby the interval between an intentional action and the subsequent perceptual outcome is typically perceived to be shorter than the actual interval. By measuring this perceptual shift using a Libet clock, we have identified an EMS-application timing that accelerates the users’ push action while maintaining their sense of agency. First, to conduct the EMS-application experiment while appropriately maintaining the intentional binding effect, we designed a new push task such that a pre-action, as the base timing of the EMS-application trigger, always occurs just before the push movement. (1) We showed the difference between the action-binding effect of EMS-induced involuntary movements and voluntary push movements. Subsequently, (2) we identified the EMS application timing that significantly shifted judgments of action tasks while accelerating voluntary movements. Additionally, (3) we demonstrated that the EMS application could accelerate user pushing movement while maintaining the sense of agency at this specific application time. The proposed EMS in the novel pushing setup was found to be robustly effective against individual and environmental changes.

Authors: Shambharkar Nitesh Laxman , Sarvade Dattatraya , Wanjari Anita
Published: September 2024

Introduction: Ethnomedicine is the study of medicinal plants and their traditional uses in treating a variety of illnesses. Research on ethnomedicine and ethnobotany has great potential to grow and produce new medications. Because medicinal plants include a variety of biologically active compounds, documenting ethnomedicinal information is crucial to the discovery of novel molecules based on traditional knowledge. Need of the study: The plant Porana paniculata Roxb. has Ethno-medicinal properties. Traditional healers in the state of Chhattisgarh use its root paste topically to treat wounds and cure bone fractures. Only a single paper has been published on its anti-inflammatory and analgesic properties. Its ability to cure wounds has not been the subject of any scientific research. Aim: The study aims to evaluate the wound-healing activity of the extract of the root of P.paniculata Roxb. in Wistar albino rats. Materials and Methods: An experimental study will be conducted at Datta Meghe College of Pharmacy and Research, Datta Meghe Institute of Higher Education and Research, Sawangi (Meghe), Wardha, Maharashtra, India from June 2024 to Dec 2024. The Botanical Survey of India (BSI) will verify the authenticity of P.paniculata Roxb. roots that will be obtained from Chhattisgarh in Grishma (mid-April to midJune) or Shishira Ritu (mid-December to mid-February). Wistar albino rats, scientific-grade chemicals, and gram-positive and gram-negative microorganisms will all be purchased from reliable sources. The preparation of an extract ointment will be employed to evaluate the activity of wound healing, in Wistar albino rats utilising an excision wound model. The antimicrobial activity will be evaluated using an Agar well diffusion technique. Data obtained will be analysed using One-way ANOVA and a p-value less than 0.05 will be considered as significant.

Authors: Sowmiya M , Basavendra Keerthana , Murugan G , Srinivasan C , Johnson Thanka
Published: September 2024

Malignant Proliferating Trichilemmal Tumour (MPTT) is a rare, malignant cutaneous adnexal tumour that originates from the outer root sheath cells of the isthmus of hair follicles. This article aims to report a rare case of a high-grade malignant trichilemmal tumour arising in the context of a proliferating Trichilemmal Cyst (TC) in a 65-year-old female who presented with a painless swelling in the left gluteal region that had been present for two months. There have been only about 100 cases reported so far. Both the clinical features and the imaging findings were suggestive of an ostensibly benign lesion. As a result, the cyst was excised; however, further histopathological evaluation revealed an unexpected case of rare MPTT. Consequently, a timely second revision surgery was performed to ensure tumour-free margins. This case illustrates that the diagnosis of MPTT is highly challenging. Without prior knowledge and a high index of suspicion, the diagnosis of MPTT could easily be missed. MPTT is often misdiagnosed as a variant of Squamous Cell Carcinoma (SCC). The subtle nuances of the unique histopathological pattern of MPTT can help differentiate it from SCC.
Exploring the Effect of Intrinsic Motivation on Chemistry Students' Achievement and Retention in Ogidi Education Zone, Anambra State: A Gender-Based Analysis
Authors: Udegbunam Chiemeka Anastasia
Published: September 2024

The study examined the effectiveness of intrinsic motivation on Chemistry students' academic achievement and retention in the Ogidi education zone of Anambra state. Employing a quasi-experimental, non-randomized control group design, the research was guided by two research questions and two null hypotheses. The study population encompassed 2,154 Senior Secondary (SS) 1 Chemistry students (1,141 females and 1,013 males) from 26 state-owned co-educational secondary schools in the Ogidi Education Zone. Using simple random sampling, two out of three local government areas were selected, and 158 Chemistry students (76 males and 82 females) were included in the sample. Schools were randomly assigned to either the intrinsic or extrinsic group. Data collection utilized the Chemistry Achievement Test (CAT), which was validated and demonstrated a reliability index of 0.81. Data analysis employed mean, standard deviation, and ANCOVA, with null hypotheses tested at a 0.05 significance level. The results indicated that female students taught Chemistry using an intrinsic motivational strategy significantly outperformed their male counterparts in achievement scores. Moreover, females taught using the intrinsic approach showed marginally better retention scores compared to males. However, no significant differences were observed in the mean achievement and retention scores between male and female students when both were taught Chemistry using the intrinsic motivational strategy. The study concluded with recommendations based on these findings.

Feature Engineering for Agile Requirement Management Using Semantic Analysis
Authors: Obike Peter G. , Obot Okure U. , Ekong Victor E.
Published: September 2024

Efficient management and prioritization of software requirements are critical challenges in agile projects, where requirements constantly evolve due to changing user needs, business goals, and regulatory updates. This paper explores the role of semantic feature extraction in enabling adaptive management strategies. Using the PROMISE Expanded Dataset and the Coquina Dataset, we employed TF-IDF weighted Word2Vec for advanced tokenization and feature extraction. Latent Dirichlet Allocation (LDA) was used to analyze how preprocessing steps like stop word removal impact topic representation, revealing that removing stop words improved topic specificity and coherence. To address class imbalance, Synthetic Minority Over-sampling Technique (SMOTE) was applied, enhancing the model's ability to handle underrepresented classes effectively. Principal Component Analysis (PCA) reduced the dimensionality of TF-IDF weighted Word2Vec embeddings from 100 features to 30, while Analysis of Variance (ANOVA) identified the most significant features for classification. The results obtained identified three features to have p-values below 0.05 as statistically significant, p-value = 0.0000605, p-value = 0.00000000469, and p-value = 0.0024. These extracted features could be used as input to training machine learning models for predicting and managing software requirements adaptively during agile development. With the reduction of ambiguities and sentiments of the user at the requirement phase, the development phase could be undertaken seamlessly with ease.

Published: July 2016

Objectives

The arrival of Neolithic farmers in Europe was the source of major cultural and genetic transitions. Neolithic settlers brought a new set of maternal lineages (mitochondrial DNA), recently well‐characterized on the continental road, from the Balkans to West Germany (Rhine River). In the present study, the first mitochondrial DNA data from groups associated with this continental expansion wave located west of the Rhine River has been provided and their genetic affinities with contemporary groups have been discussed.

Material and methods

The mitochondrial DNA analysis of 27 human remains originating from Obernai (5,000–4,400 cal. BC), a necropolis located in French Alsace Region and attributed to Grossgartach, Planig–Friedberg, and Roessen cultures was conducted.

Results and discussion

Among the 27 individuals studied, 15 HVR‐I sequences and 17 mitochondrial haplogroups could be determined. The analysis of the Obernai gene pool clearly confirmed the genetic homogeneity of Linearbandkeramik (LBK) groups on both sides of the Rhine River. Notably, one N1a sequence found in Obernai is shared with LBK farmers from Central Europe, including one individual from the Flomborn site located approximately 200 km north‐east of Obernai. On the whole, data gathered so far showed major genetic influence of the Danubian wave from Transdanubia to Atlantic French Coast, going by Alsace Region. However, the genetic influence of descendants from the Mediterranean Neolithic expansion and the significant hunter‐gatherer admixture detected further west in the Paris Basin were not perceived in the Obernai necropolis.

Conclusions

Genetic homogeneity and continuity within LBK groups can be proposed on both sides of the Rhine River for the middle Neolithic groups. Nevertheless, mitochondrial data gathered so far for Neolithic groups from the entire extant French Territory clearly point out the complexity and the variability of Neolithic communities interactions that is worthy of further investigation.

Published: July 2016

The past fifty years have been an epoch of impressive progress in the field of astronomical technology. Practically all the technical tools, which we use today, have been developed during that time span. While the first half of this period has been dominated by advances in the detector technologies, during the past two decades innovative telescope concepts have been developed for practically all wavelength ranges where astronomical observations are possible. Further important advances can be expected in the next few decades. Based on the experience of the past, some of the main sources of technological progress can be identified.

Phytochemical Profile, Chemotaxonomic Studies, and In Vitro Antioxidant Activities of Two Endemisms from Madeira Archipelago: Melanoselinum decipiens and Monizia edulis (Apiaceae)
Authors: Spínola Vítor , Castilho Paula C.
Published: July 2016

Melanoselinum decipiens and Monizia edulis (Apiaceae) are two endemic plants from Madeira archipelago, phytochemical compositions of which remains little explored, despite their use in folk medicine. Using liquid chromatography with diode array and electrospray ionization/mass spectrometry analysis, their polyphenolic profile was established for the first time. Fifty‐six compounds were identified with 5‐O‐caffeoylquinic acid, quercetin‐O‐(malonyl)hexoside, luteolin diacetyl, and quercetin‐O‐hexoside being the major constituents in the leaves of both plant species (≥ 0.76 mg/g of dry extract). Principal component analysis provided a suitable tool to differentiate targeted plants. Naringenin‐6,8‐di‐C‐glucoside, quercetin 3‐O‐pentosylhexoside, and 1,5‐O‐dicaffeoylquinic acid can be used as discriminatory taxonomic/geographical markers for M. edulis subspecies from Madeira and Porto Santo populations. This methodology of using polyphenols as chemotaxonomic markers proved to be useful for identification of plant species since the results are consistent with previous taxonomical data. The free‐radical scavenging activities of the M. decipiens extracts proved to be higher than those of M. edulis, which correlated well with their phenolic content (R2 > 0.906).

Supervised neighborhood preserving embedding for feature extraction and its application for soft sensor modeling
Authors: Yuan Xiaofeng , Ge Zhiqiang , Ye Lingjian , Song Zhihuan
Published: July 2016

Neighborhood preserving embedding (NPE) is a useful tool for learning the manifold of high‐dimensional data. As a linear approximation of nonlinear locally linear embedding, NPE can be applied to dimensionality reduction by neighborhood preserving. However, the original NPE algorithm is an unsupervised method, which extracts features without any reference to the output information. In this paper, a supervised NPE framework is proposed for output‐related feature extraction in soft sensor applications. In the supervised NPE framework, the output information is utilized to guide the procedures for constructing the adjacent graph and calculating the weight matrix, with which the intrinsic structure of the data can be better described. For performance evaluation of the proposed method, experiments on a numerical example and an industrial debutanizer column process are carried out. The results show the effectiveness of the proposed framework.
Lanthanide Tetrazolate Complexes Combining Single‐Molecule Magnet and Luminescence Properties: The Effect of the Replacement of Tetrazolate N3 by β‐Diketonate Ligands on the Anisotropy Energy Barrier

Published: July 2016

Three new sets of mononuclear LnIII complexes of general formulas [LnL3]⋅CH3OH [LnIII=Yb (1), Er (2), Dy (3), Gd (4), and Eu (5)], [LnL2(tmh)(CH3OH)]⋅n H2O⋅m CH3OH [LnIII=Yb (1 b), Er (2 b), Dy (3 b), Gd (4 b)], and [LnL2(tta)(CH3OH)]⋅CH3OH [LnIII=Yb (1 c), Er (2 c), Dy (3 c), Gd (4 c)] were prepared by the reaction of Ln(CF3SO3)⋅n H2O salts with the tridentate ligand 2‐(tetrazol‐5‐yl)‐1,10‐phenanthroline (HL) and, for the last two sets, additionally with the β‐diketonate ligands 2,2,6,6‐tetramethylheptanoate (tmh) and 2‐thenoyltrifluoroacetonate (tta), respectively. In the [LnL3]⋅CH3OH complexes the LnIII ions are coordinated to three phenanthroline tetrazolate ligands with an LnN9 coordination sphere. Dynamic ac magnetic measurements on 1–3 reveal that these complexes only exhibit single‐molecule magnet (SMM) behavior when an external dc magnetic field is applied, with Ueff values of 11.7 K (1), 16.0 K (2), and 20.2 K (3). When the tridentate phenanthroline tetrazolate ligand is replaced by one molecule of methanol and the β‐diketonate ligand tmh (1 b–3 b) or tta (1 c–3 c), a significant increase in Ueff occurs and, in the case of the DyIII complexes 3 b and 3 c, out‐of‐phase χ′′ signals below 15 and 10 K, respectively, are observed in zero dc magnetic field. CASSCF+RASSI ab initio calculations performed on the DyIII complexes support the experimental results. Thus, for 3 the ground Kramers’ doublet is far from being axial and the first excited state is found to be very close in energy to the ground state, so the relaxation barrier in this case is almost negligible. Conversely, for 3 b and 3 c, the ground Kramers’ doublet is axial with a small quantum tunneling of the magnetization, and the energy difference between the ground and first Kramers’ doublets is much higher, which allows these compounds to behave as SMMs at zero field. Moreover, these calculations support the larger Ueff observed for 3 b compared to 3 c. Additionally, the solid‐state photophysical properties of 1, 2, 4, and 5 show that the phenanthroline tetrazolate ligand can act as an effective antenna to sensitize the characteristic YbIII, ErIII, and EuIII emissions through an energy‐transfer process.
Boron Lewis Acid‐Catalyzed Hydroboration of Alkenes with Pinacolborane: BArF3 Does What B(C6F5)3 Cannot Do!
Authors: Yin Qin , Kemper Sebastian , Klare Hendrik F. T. , Oestreich Martin
Published: July 2016

The transition‐metal‐free hydroboration of various alkenes with pinacolborane (HBpin) initiated by tris[3,5‐bis(trifluoromethyl)phenyl]borane (BArF3) is reported. The choice of the boron Lewis acid is crucial as the more prominent boron Lewis acid tris(pentafluorophenyl)borane (B(C6F5)3) is reluctant to react. Unlike B(C6F5)3, BArF3 is found to engage in substituent redistribution with HBpin, resulting in the formation of ArFBpin and the electron‐deficient diboranes [H2BArF]2 and [(ArF)(H)B(μ‐H)2BArF2]. These in situ‐generated hydroboranes undergo regioselective hydroboration of styrene derivatives as well as aliphatic alkenes with cis diastereoselectivity. Another ligand metathesis of these adducts with HBpin subsequently affords the corresponding HBpin‐derived anti‐Markovnikov adducts. The reactive hydroboranes are regenerated in this step, thereby closing the catalytic cycle.

Validation of a method for the determination of 120 pesticide residues in apples and cucumbers by LC‐MS/MS
Authors: Ramadan Gouda , Al Jabir Muna , Alabdulmalik Najat , Mohammed Ali
Published: July 2016

Most countries have clearly defined regulations governing the use of pesticides in agricultural activity. The application of pesticides in agriculture usually leads to a residual amount of these pesticides on food products such as fruit and vegetables. The presence of pesticide residues on these foods destined for human consumption may pose food safety risks to consumers. To protect consumers, national authorities have established maximum limits for pesticide residues in foods. These limits can only be enforced if there are methods available to detect and monitor their concentrations in the applicable food products. To support the enforcement of this legislation, we have developed a multi‐residue liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) method for the analysis of 120 pesticide residues in apples and cucumbers which has been validated and implemented in the routine monitoring and surveillance programme for these pesticides. In this method, apple and cucumber samples are extracted using the QuEChERS method (quick, easy, cheap, effective, rugged, and safe) and the extracts were analyzed directly by LC‐MS/MS. The mean recoveries at three different concentrations of 0.01 µg/g , 0.05 µg/g, and 0.1 µg/g over the analytical range varied between 70 and 120%. The repeatability of the method expressed as %RSD was less than 20%. The limit of detection (LOD) of the method ranged between 0.0014 and 0.0110 µg/g for apples and between 0.0012 and 0.0075 µg/g for cucumbers. The limit of quantification (LOQ) of the method was 0.01 µg/g for apples and cucumbers. The method has been used for the analysis of over 600 apple and 550 cucumber samples over the past two years.
