Zebra: When Temporal Graph Neural Networks Meet Temporal Personalized PageRank
Authors: Li Yiming , Shen Yanyan , Chen Lei , Yuan Mingxuan
Published: April 2023

Temporal graph neural networks (T-GNNs) are state-of-the-art methods for learning representations over dynamic graphs. Despite the superior performance, T-GNNs still suffer from high computational complexity caused by the tedious recursive temporal message passing scheme, which hinders their applicability to large dynamic graphs. To address the problem, we build the theoretical connection between the temporal message passing scheme adopted by T-GNNs and the temporal random walk process on dynamic graphs. Our theoretical analysis indicates that it would be possible to select a few influential temporal neighbors to compute a target node's representation without compromising the predictive performance. Based on this finding, we propose to utilize T-PPR, a parameterized metric for estimating the influence score of nodes on evolving graphs. We further develop an efficient single-scan algorithm to answer the top-
k
T-PPR query with rigorous approximation guarantees. Finally, we present Zebra, a scalable framework that accelerates the computation of T-GNN by directly aggregating the features of the most prominent temporal neighbors returned by the top-
k
T-PPR query. Extensive experiments have validated that Zebra can be up to two orders of magnitude faster than the state-of-the-art T-GNNs while attaining better performance.

Countrywide and worldwide business, like gaming and social networks, drives the popularity of inter-data-center transactions. To support inter-data-center transaction processing and data center fault tolerance simultaneously, existing protocols suffer from significant performance degradation due to high-latency and unstable networks. In this paper, we propose RedT, a novel distributed transaction processing protocol that works in heterogeneous networks. In detail, nodes within a data center are inter-connected via the RDMA-capable network and nodes across data centers are inter-connected via TCP/IP networks. RedT extends two-phase commit (2PC) by decomposing transactions into sub-transactions in terms of the data center granularity, and proposing a pre-write-log mechanism that is able to reduce the number of inter-data-center round-trips from a maximal of 6 to 2. Extensive evaluation against state-of-the-art protocols shows that RedT can achieve up to 1.57× higher throughputs and 0.56× lower latency.
Sparkly: A Simple yet Surprisingly Strong TF/IDF Blocker for Entity Matching
Authors: Paulsen Derek , Govind Yash , Doan AnHai
Published: April 2023

Blocking is a major task in entity matching. Numerous blocking solutions have been developed, but as far as we can tell, blocking using the well-known tf/idf measure has received virtually no attention. Yet, when we experimented with tf/idf blocking using Lucene, we found it did quite well. So in this paper we examine tf/idf blocking in depth. We develop Sparkly, which uses Lucene to perform top-k tf/idf blocking in a distributed share-nothing fashion on a Spark cluster. We develop techniques to identify good attributes and tokenizers that can be used to block on, making Sparkly completely automatic. We perform extensive experiments showing that Sparkly outperforms 8 state-of-the-art blockers. Finally, we provide an in-depth analysis of Sparkly's performance, regarding both recall/output size and runtime. Our findings suggest that (a) tf/idf blocking needs more attention, (b) Sparkly forms a strong baseline that future blocking work should compare against, and (c) future blocking work should seriously consider top-k blocking, which helps improve recall, and a distributed share-nothing architecture, which helps improve scalability, predictability, and extensibility.

Fatty liver disease has mainly been characterized under fasting conditions. However, as the liver is essential for postprandial homeostasis, identifying postprandial disturbances may be important. Here, we investigated postprandial changes in markers of metabolic dysfunction between healthy individuals, obese individuals with non‐alcoholic fatty liver disease (NAFLD) and patients with cirrhosis. We included individuals with biopsy‐proven NAFLD (n = 9, mean age 50 years, mean BMI 35 kg/m2, no/mild fibrosis), cirrhosis with hepatic steatosis (n = 10, age 62 years, BMI 32 kg/m2, CHILD A/B) and healthy controls (n = 10, age 23, BMI 25 kg/m2), randomized 1:1 to fasting or standardized mixed meal test (postprandial). None of the patients randomized to mixed meal test had type 2 diabetes (T2D). Peripheral blood was collected for 120 min. After 60 min, a transjugular liver biopsy and liver vein blood was taken. Plasma levels of glucose, insulin, C‐peptide, glucagon, and fibroblast growth factor 21 (FGF21) were measured. Postprandial peak glucose and C‐peptide were significantly increased in NAFLD, and cirrhosis compared with healthy. Patients with NAFLD and cirrhosis had hyperglucagonemia as a potential sign of glucagon resistance. FGF21 was increased in NAFLD and cirrhosis independent of sampling from the liver vein versus peripheral blood. Glucagon levels were higher in the liver vein compared with peripheral blood. Patients with NAFLD and cirrhosis without T2D showed impaired glucose tolerance, hyperinsulinemia, and hyperglucagonemia after a meal compared to healthy individual. Postprandial characterization of patients with NAFLD may be important to capture their metabolic health.

Published: April 2023

Pemphigus Vulgaris (PV) is a blistering autoimmune disease caused by autoantibodies against desmoglein 1 and 3. Treatment options are limited to corticosteroids and immunosuppressants. The myotoxic effect of glucocorticoids is a fact that has been elucidated. So, the development of efficacious treatment approaches to combat muscle wasting is of great importance. Considering the adverse effect of glucocorticoid therapy in pemphigus patients and altered muscle metabolism, this study aimed to investigate the effect of l‐carnitine supplementation which can be useful in combating muscle‐wasting impact of glucocorticoid therapy. In this randomized double‐blind placebo‐controlled trial 44 pemphigus patients aged from 30 to 65 years, receiving glucocorticoid therapy were selected to evaluate the suitability of l‐carnitine (LC) as an anti‐wasting substance. Patients were randomly divided into two groups to receive 2 g/d l‐carnitine or placebo for 8 weeks; serum markers of muscle metabolism (IGF‐1, creatine kinase, myogenin, myostatin) was evaluated before and after the l‐carnitine supplementation. Paired T‐test was used to analyze the differences between variables before and after the intervention. Therefore, the student's t‐test was performed to find any differences in baseline characteristics and dietary intakes between the trial groups. LC intake led to a significant rise in serum IGF‐1 and a reduction in CK and myostatin levels compared to baseline (p < 0.05) but there were no significant inter‐group differences in IGF‐1 and CK levels; There was also a significant reduction in myostatin level in LC group (p < 0/05). Myogenin levels decreased in both LC and placebo groups but the decrease in the placebo group was significant (p = 0/008); it means LC prevent the myogenin decreasing trend in the LC group compared to placebo. In conclusion, LC supplementation beneficially changes the level of IGF‐1 and myostatin and improves muscle metabolism and regeneration in PV patients.
The interplay of contrast markers (‘but’), selectives (“topic markers”) and word order in the fuzzy oppositive contrast domain
Authors: Wälchli Bernhard
Published: April 2023

This investigation is a large-scale comparative corpus study of the oppositive contrast domain (also called “semantic opposition”) based on parallel texts. Oppositive contrast is established as a fuzzy region of the similarity space of contrast (‘but’), a domain also characterized by the occurrence of selectives (“topic markers”) and of initial non-predicative phrases in VSO/VOS-languages. Major findings are that many languages have special oppositive contrast markers and that there is a continuum between oppositive contrast markers and selectives, although truly intermediate markers are rare. The gradualness between oppositive and counterexpectative contrast is explained by semantic fuzziness and by emphasis, with strong emphasis being dependent on scales. Contrast is a rhetorical discourse relation and strong oppositive contrast can be used as a persuasive strategy aiming at establishing new common ground stepwise. The fuzziness of oppositive contrast has major theoretical and methodological implications. The encoding of the domain neither follows strict universals nor is it maximally diverse (diversity is strongly constrained). Due to its syntactic properties, oppositive contrast cannot be conceived of merely as a preestablished extralinguistic semantic domain. Furthermore, contrast exhibits a high degree of language-internal variability. General trends are reflected both by stable and by emergent grammar.

We used Maxent to model the distribution of the Nilgiri marten (Martes gwatkinsii), a cryptic semi-arboreal mammal, with climate, forest, and human disturbance as covariates. We modelled the species niche, which identified suitable habitat across a variety of land uses and protection regimes. The findings point to a species niche defined by isolated, cold, and wet areas along the Western Ghats’ montane grasslands (shola) and adjoining wet forests. A sizable portion (62 %) of the total 8922 km2 niche area is multi-use, including tea, coffee, and timber plantations. Our findings emphasise the importance of conservation in non-protected areas adjacent to reserves in order to sustain this endemic species.
Recent advances in oblique plane microscopy
Authors: Kim Jeongmin
Published: April 2023

Oblique plane microscopy (OPM) directly captures object information in a plane tilted from the focal plane of the objective lens without the need for slow z-stack acquisition. This unconventional widefield imaging approach is made possible by using a remote focusing principle that eliminates optical aberrations for object points beyond the focal plane. Together with oblique lightsheet illumination, OPM can make conventional lightsheet imaging fully compatible with standard biological specimens prepared on microscope slides. OPM is not only an excellent high-speed volumetric imaging platform by sweeping oblique lightsheet illumination without mechanically moving either the sample or objective lens in sample space, but also provides a solution for direct oblique plane imaging along any orientation of interest on the sample in a single shot. Since its first demonstration in 2008, OPM has continued to evolve into an advanced microscope platform for biological, medical, and materials science applications. In recent years, many technological advances have been made in OPM with the goal of super-resolution, fast volumetric imaging, and a large imaging field of view, etc. This review gives an overview of OPM’s working principle and imaging performance and introduces recent technical developments in OPM methods and applications. OPM has strong potential in a variety of research fields, including cellular and developmental biology, clinical diagnostics in histology and ophthalmology, flow cytometry, microfluidic devices, and soft materials.

Published: April 2023

The magmatic diagenetic environment was simulated by high-temperature melting and natural cooling. A series of glass-ceramics with different Nd2O3 contents were prepared by using complex component granite (aluminosilicate material). The phase evolution of the matrix at different temperatures was studied by X-ray diffraction (XRD). The structure of glass-ceramics was analyzed by infrared spectroscopy (IR) and scanning electron microscopy (SEM). The mechanical properties of glass-ceramics were also evaluated. The results showed that the glass transition of pure matrix begins at 1200 °C, and the sample with the highest degree of vitrification is obtained at 1500 °C. The addition of Nd2O3 promoted the melting of Fe3O4 crystal, resulting in the complete amorphous matrix when the Nd2O3 amount is in the range of 20–26 wt.%. With the further increase of Nd2O3 content, Nd-bearing feldspar first appeared. No raw material Nd2O3 was found, indicating that the formation of Nd-bearing feldspar may increase the carrying capacity of the material. The Gaussian fitting results showed that the glass-ceramic samples with Nd2O3 content of 29 wt.% are mainly composed of Q2 and Q3 structural units. In the EDS result, part of neodymium was clustered with small bright spots, while the spots were uniformly distributed on the sample surface as a whole. Meanwhile, the addition of Nd2O3 increased the mechanical properties of the samples (3.20 g/cm3, 8.33 GPa for the sample with 29 wt.% of Nd2O3). The results provide a strategy for the treatment of solid waste with radioactive residual actinides.

Published: April 2023

Falls resulting from trips are a leading cause of injury and can sometimes result in death, especially in the older population. Numerous researchers have studied the biomechanical mechanisms that differentiate fallers from nonfallers and determined whether training can beneficially impact those outcomes. Exercise and task-specific interventions have demonstrated fewer falls after trips but can be costly and often require specialized equipment, making their applicability less practical. Qualified health and fitness practitioners can develop evidence-informed, exercise-based programs focusing on 3 components (balance training, task-specific training, and resistance exercise). Such programs may help to reduce fall risk in older adults based on previously documented studies identifying the biomechanical demands of a successful fall arrest after a trip perturbation. These multicomponent programs should include a safe task-specific training element that does not require specialized equipment.
Interpretation of Small-Scaled Model Test for Uniform Clay Slope Design
Authors: Wang Xiaoliang , Zhou Mi , Zhang Xihong
Published: April 2023

Small-scaled model tests under normal gravity are widely used to examine slope stabilities and failure mechanisms. Nevertheless, in practice, it is impossible to comply to all similarity principles, which could affect the modeled results in the prototype. This paper performs finite element analyses to investigate the behavior of uniform clay slopes as commonly performed in a 1g model test without following similarity principles. The numerical model is validated with previously published data. A parametric study is then carried out with varying slope scales, soil properties, etc. Based on extensive numerical modeling data, four formulas are established to correlate and interpolate the sliding surface and safety factor of a model slope in a 1g test. A framework is proposed to interpret 1g model-scale test results for applications in slope designs.

Authors: Fang Xiangwei , Hu Fenghui , Yao Zhihua , Chen Zhenghan , Shen Chunni
Published: April 2023

In order to study the macro and micro-mechanical properties of a soil sample under high pressure, we improved the traditional triaxial apparatus with high-bearing pressure for soil by combining it with the computed tomography (CT) system. The new apparatus overcomes the existing limits of low bearing pressure in the traditional triaxial apparatus and the small sample size in the micro-CT triaxial apparatus, keeping all the functions of the traditional triaxial apparatus. It can attain dynamic, quantitative, and noninvasive scanning of the internal structure of soil samples during the testing process. Moreover, the pressure chamber is made of high-strength and lightweight aircraft aluminum materials, allowing high X-ray penetration while ensuring that the scanned image is clear under high pressure. Consolidated undrained and drained triaxial tests are conducted by the apparatus on coral sand. The results show that the stress–strain curve is reasonable, the CT image is clear, and the particle breakage in the real-time loading process can be analyzed through image processing in single grading. As a result, the apparatus can be used to study the micro-mechanism of the internal structure of soil aiming at explaining its macro-mechanical behavior.

Mycobacterium tuberculosis (Mtb) secretes extracellular vesicles (EVs) containing a variety of proteins, lipoproteins, and lipoglycans. While emerging evidence suggests that EVs contribute to tuberculosis pathogenesis, the factors and molecular mechanisms involved in mycobacterial EV production have not been identified. In this study, we use a genetic approach to identify Mtb proteins that mediate vesicle release in response to iron limitation and antibiotic exposure. We uncover a critical role for the isoniazid‐induced, dynamin‐like proteins, IniA and IniC, in mycobacterial EV biogenesis. Further characterization of a Mtb iniA mutant shows that the production of EVs enables intracellular Mtb to export bacterial components into the extracellular environment to communicate with host cells and potentially modulate the immune response. The findings advance our understanding of the biogenesis and functions of mycobacterial EVs and provide an avenue for targeting vesicle production in vivo.
The aspiration of voiceless stops by Brazilian learners in contexts of authentic communication
Authors: Neder Neto Tufi
Published: April 2023

This paper aims at studying the production of aspiration by Brazilian learners of English. Aspiration is a quick projection of air released after voiceless stops when they are found in stressed syllables before vowel sounds. It is measured in milliseconds and is usually longer in native speakers than learners (Alves & Magro 2011). Most importantly, aspiration contributes decisively to intelligibility (Jenkins 2000). So, an understanding of the way aspiration operates in the speech of learners is important to help them improve their oral communication abilities. We analysed the recordings of ten students of Letters who were at intermediate or advanced levels of command of the language, totalizing 1590 occurrences. Those recordings compose the oral corpus LINDSEI-BR, which is the Brazilian branch of the LINDSEI project. Instead of controlled activities of reading texts in laboratories, the participants could talk freely about a variety of topics, in a context which was very similar to spontaneous speech in authentic communication. The length of aspiration was analysed using the software PRAAT. Our results revealed aspects regarding the students’ production of aspiration which had not been detected in similar studies and, thus, can provide future ones with other ways of looking into the phenomenon.

Cyber security management in the system for ensuring nationally rooted resilience of economic development
Authors:   State Institution “Institute for Economics and Forecasting, NAS of Ukraine”, Mishchenko Volodymyr
Published: April 2023

In the course of the study, it has been found that the increase in volumes and the expansion of the spheres of the use of digital technologies objectively cause the emergence of cyber threats and expose all participants of digital ecosystems to cyber risks, which restrains economic development. It has been proven that the presence of a wide range of factors that shape cyber security and cyber resilience requires the implementation of a comprehensive approach to the formulation of protective strategies of companies and institutions. The article argues that the process of organizing cyber resilience management should be based on the development of comprehensive cyber protection systems based on clear policies, rules and strategies for early detection, prevention and minimization of consequences of the implementation of cyber threats using a wide range of technical, technological, organizational, managerial and regulatory measures. The author justifies the need to develop national strategy and program for the authorities in the spheres of legislation, regulation, supervision and control over the state of cyber security. He proves that the national cyber defense strategy should provide for effective measures to protect critical infrastructure objects, state authorities and the population, as well as a system of regulatory and supervisory measures. The author establishes that the primary task for the organization and operation of cyber protection systems should be the protection of digital assets and of the companies’ resources and their customers. In order to strengthen the institutional capacity of authorities to effectively support the national cyber security ecosystem, a structural and logical scheme of interaction between companies and the State Cyber Protection Center of Ukraine in the process of exchanging information about cyber incidents has been developed, and practical recommendations have been provided for the interaction between critical infrastructure objects and state regulatory bodies, which can be used to ensure nationally rooted stability and security of Ukraine’s economic development in a hybrid "peace-war" system.
Decoherence in a PT -Symmetric Qubit
Authors: Bhat J.M. , Lone M.Q. , Datta S. , Dar G.N. , Farouk A.
Published: April 2023

We investigate the decoherence in a PT -symmetric qubit coupled with a bosonic bath. Using canonical transformations, we map the non-Hermitian Hamiltonian representing the PT-symmetric qubit to a spin boson model. Identifying the parameter α that demarcates the hermiticity and non-hermiticity in the model, we show that the qubit does not decohere at the transition from the real eigen spectrum to a complex eigen spectrum. Using a general class of spectral densities, the strong suppression of the decoherence is observed due to both vacuum and thermal fluctuations of the bath, and the initial correlations hold, as we approach the transition point.

Published: April 2023

Aquatic insect communities in inland waters of Chile are characterised by the presence of certain species depending on water quality, but there is little information on statistical ecology in the structure of insect communities. The aim of the present study was to apply null models to explain the structure of aquatic insects in the middle zone of the Loa River, in the Atacama Desert (Antofagasta Region, Chile; 23°S). The results of the null models of species co-occurrence showed that species associations are random, while niche sharing showed that species share ecological niches and consequently there is interspecific competition. The reported taxa are similar to communities for other North Patagonian rivers in terms of community structure.

Authors: Kadek Enny Pradnyaswari  , Romy Windiyanto
Published: April 2023

Background: perinatal asphyxia is the second-highest cause of neonatal death in Indonesia. According to the World Health Organization (WHO), perinatal asphyxia is when a baby experiences spontaneous and regular breathing failure immediately after birth. Various risk factors may cause perinatal asphyxia, including maternal, fetal, and placental factors. This study aims to identify the risk factors associated with the incidence of perinatal asphyxia at the Sanjiwani Regional General Hospital, Gianyar.
Methods: This research was an observational analytic study with a case-control design involving 114 samples of newborns from January 1 to December 31, 2022, at the Sanjiwani Gianyar Hospital. The case group was selected using a total sampling technique, and the control group using a simple random sampling technique. Data were extracted from the medical records and analyzed using univariate, bivariate, and multivariate methods. Bivariate analysis used Chi-square or Fisher's exact tests, while multivariate analysis used logistic regression. The P-value of <0.05 is considered significant.
Results: A total of 57 cases and 57 controls were included in this study. The bivariate analysis found the factors associated with perinatal asphyxia were meconium-stained amniotic fluid (p=0.021; OR=2.742; 95%CI=1.150-6.539), mode of delivery (p=0.003; OR=3.203; 95%CI=1.484-6.913), low birth weight (p=0.002; OR=4.595; 95%CI=1.681-12.561), and prematurity (p=0.006; OR=4.732; 95%CI=1.462-15.322). In multivariate analysis, it was found that meconium-stained amniotic fluid has the strongest association with perinatal asphyxia.
Conclusion: There is a significant relationship between meconium-stained amniotic fluid, method of delivery, low birth weight, and prematurity with the incidence of perinatal asphyxia.

Published: April 2023

Background: Low-grade chronic inflammation may contribute to the development of atherosclerosis as well as hypertension by inducing the production of pro-inflammatory cytokines. Several studies have revealed a relationship between the microbiota living in the gut and the incidence of hypertension. Two of several gut microbiota that contributed, in this case, are Escherichia coli (E. coli) and Roseburia intestinalis (R. intestinalis). Therefore this study aimed to identify and quantify gut microbes namely R. intestinalis and E.coli in hypertensive patients in Bali, especially in Denpasar City.
Methods: This research is a cross-sectional study located at South Denpasar Health Center I, Bali, and the Integrated Biomedical Laboratory, Faculty of Medicine, Universitas Udayana. The sample in this study were hypertensive patients who had been registered at South Denpasar Health Center I and who met the inclusion criteria and did not meet the exclusion criteria. The E. coli and R. intestinalis concentrations were assessed by conducting DNA isolation and RT-qPCR. Statistical analysis using univariate analysis, bivariate analysis using the Independent T-Test; Mann-Whitney Test; Chi-Square, and ROC analysis
Results: There were 70 subjects included in this study. Thirty-one subjects were hypertensive patients and the other 39 patients were not hypertensive. The age of the subjects between the two groups was found statistically significant (p=0.007). We also found that comorbid were found mostly in hypertensive patients (p=0.009). Most of the comorbid experienced among them were cardiovascular diseases and diabetes mellitus. Hypertensive subjects had more E. coli concentration in their gut compared with non-hypertensive subjects (p=0.048), while R. intestinalis concentrations were similar in both groups (p>0.05). From the multivariate analysis, it was found that hypertensive patients tended to have a higher concentration of E. coli than non-hypertensive patients (p=0.012; 95% CI:0.055–0.417).
Conclusion: E. coli concentration in the gut is independently associated with the incidence of hypertension, while R. intestinalis concentration is not.

Herein, we report a convenient one-pot synthesis of 1,2,4-triazinyl derivatives of benzocoumarins. The proposed approach consists in the nucleophilic addition of tetrahydrobenzo annulated dimethoxycoumarin to 1,2,4-triazines followed by double oxidation of both dihydrotriazine and tetrahydrobenzo groups with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). The nucleophilic addition of the dimethoxycoumarin to 1,2,4-triazines was carried out in the presence of three-fold excess of methanesulfonic acid in DCM at room temperature and take place between positions 4 and 5 of coumarin and 1,2,4-triazine, respectively. The double oxidation step was achieved with 3.6 equivalent of DDQ. Selective oxidation of dihydrotriazine moiety, without affecting the tetrahydrobenzo fragment, was achieved using 1.2 equivalent of tetrachlorobenzoquinone (TCQ). The differences in the oxidation with TCQ and DDQ appear to be related to the higher oxidative potential of DDQ in contrast to TCQ. The advantages of the method are the elimination of the use of transition metals, the availability of starting materials, and the simplicity of the procedure. The proposed approach provides a two-step one-pot protocol for the synthesis of triazinyl benzocoumarins, precursors for the preparation of push-pull pyridinyl chromophore.

Active development of electrochemical devices such as proton-conducting fuel cells and electrolyzers should ensure sustainable environmental development. An electrolyte material of a hydrogen-powered electrochemical device must satisfy a number of requirements, including high proton conductivity. Layered perovskites are a promising class of proton-conducting electrolytes. The cationic co-doping method has been successfully applied to well-known proton conductors with the classical perovskite structure ABO3. However, the data on the application of this method to layered perovskites are limited. In this work, the bilayer perovskites BaLa1.9Sr0.1In1.95M0.05O6.925 (M = Mg2+, Ca2+) were obtained and investigated for the first time. Cationic co-doping increases oxygen-ion and proton conductivity values.
THE COMMODIFICATION OF JOB VACANCIES: MARKET PRACTICES OF EMPLOYMENT AGENCIES FEES IN RIO DE JANEIRO (1950-1975)
Authors: Lima Léa
Published: April 2023

Abstract “Labor is not a commodity”: One of the earliest understandings of this maxim concerns the intermediation of employment by supporting policies to extinguish the fees charged to workers for their placement. In Brazil, employment agencies fees never disappeared. The article goes back to the period of expansion of private intermediation in Rio de Janeiro, from 1950 to 1975, to observe their market practices. In order to attract job seekers and convince them to pay for an intermediation service, we argue that those actors performed the commodityhood of job vacancies. We analyzed a sample of 3556 job and employment agencies ads published in the Jornal do Brasil, from 1945 to 1975, highlighting three social processes of commoditization of job vacancies: the objectivation of job vacancies as “real things to be bought,” the performing of profusion and collection of job vacancies as “things to be chosen,” and the social ascension rhetoric of the unemployed to the status of customer. With the employment agencies work market, the world of labor appears as colonized by techniques, codes, and expectations from world of mass consumption.
Effect of compaction water on strength and hydraulic properties of bentonite-based liner
Authors: Rout Suryaleen , Singh Suresh Prasad
Published: April 2023

The abundance of pond ash and its resemblance to natural sand encourages its use as a substitute for sand in sand–bentonite (SB) liner material. Compaction water content influences the geoengineering properties of cohesive soil to a great extent. Accordingly, the compaction, strength, permeability and shrinkage characteristics of both pond ash–bentonite (PAB) and SB mixes are investigated at standard and modified Proctor compaction energies at various water contents to support the recommendation of the PAB mixture as an alternative landfill liner. At similar compaction conditions, the PAB mix exhibits higher unconfined compressive strength (UCS) and hydraulic conductivity than the SB mix. The UCS values of mixes compacted on the dry side of optimum are higher than those of mixes compacted on the wet side. Dry-side compacted mixes exhibit a reduction in hydraulic conductivity with permeation time, whereas no substantial reduction in hydraulic conductivity is noticed for wet-side compacted mixes. Furthermore, the volumetric shrinkage of both PAB and SB mixes is within the permissible value of 4%, for a wide range of water variation from the dry to the wet side of optimum. The observed mechanical properties are correlated to the shape of coarse fraction particles and the corresponding microstructural arrangements of the compacted specimens.

A new species of Nama (Namaceae) from the Vizcaino Desert, Mexico
Authors: León de la Luz José Luis , Rebman Jon P. , Medel Narváez Alfonso
Published: April 2023

Background: Although most of the Nama taxa grow on sandy substrates, none of them is restricted to the coastal dune environment. A small population of a unique looking taxon was found on the Pacific coast of the Baja California peninsula, which is here presented as a new species.
Question and/or Hypothesis: In the morphological analysis in the individuals of a putative new taxon, some peculiarities stand out, such as a suffruticose herbaceous perennial growth form with erect and compact branching, featuring a small cushion, unlike the rest of the known species, which are rather procumbent, or erect in form. It also has revolute leaf margins in the blade.
Studied Species: Nama asuncionensis sp. nov. (Namaceae) and morphologically similar species.
Study Site: Central Pacific coast of Baja California, Mexico.
Method: Through bibliographic consultation, review of herbarium specimens, and photographs, a comparative morphological analysis was carried out with other Nama species of the peninsula and mainland Mexico.
Results: Based on the comparative analyses, Nama asuncionensis is here presented and illustrated as a new species.
Conclusions: Nama asuncionensis is a micro-endemic species restricted to the Pacific coastal environment of the peninsula. We propose that this new taxon be included in the Eunama section of the genus based on its morphological characteristics, including a membranous loculicidal dehiscent capsule, free styles, and sepals divided to the base. This taxon seems to be limited to a narrow coastal strip, with high relative humidity, where it develops its fresh leaves and flowers during the mild season.

Objectives

Distress and associated health problems reported by Nunavik Inuit emanate from heterogeneous roots, including adverse childhood experiences. This study aims to (1) identify distinct childhood adversity profiles and (2) examine associations between these profiles and sex, socioeconomic characteristics, social support, and community involvement among Nunavimmiut.

Methods

In a sample of 1109 adult Nunavimmiut, sex, socioeconomic characteristics, support, community involvement, residential school attendance, and 10 forms of adverse childhood experiences (ACEs) were documented using questionnaires. Latent class analyses and weighted comparisons were performed for three subgroups: 18–49 years; 50 years and above with experience of residential school; and 50 years and above without experience of residential school. The analysis design, the manuscript drafts, and the key findings were discussed and co-interpreted with the collaboration of community representatives, taking into consideration Inuit culture and needs.

Results

A total of 77.6% of Nunavimmiut reported having experienced at least one form of childhood adversity. Three ACE profiles were identified among the 18–49-year-olds: low ACEs (43.0%), household stressors (30.7%), and multiple ACEs (26.3%). Two profiles characterized ACEs experienced among the 50-year-olds and over with and without history of residential schooling: low ACEs (80.1% and 77.2%, respectively) and multiple ACEs (19.9% and 22.8%, respectively). Among the group of 18–49-year-olds, as compared to the low ACE profile, the profile with household stressors included proportionally more women (odds ratio [OR] = 1.5) and was associated with lower involvement in volunteering and community activities (mean score reduced by 0.29 standard deviation [SD]) and lower family cohesion (SD = − 0.11), while the multiple ACE profile was related to a lower rate of employment (OR = 0.62), lower family cohesion (SD = − 0.28), and lower satisfaction with ability to practice traditional activities (SD = − 0.26).

Conclusion

Childhood adversities among Nunavimmiut do not occur in isolation and experiencing multiple forms of childhood adversities predicts lower socioeconomic status, support, and community involvement in adulthood. Implications for the planning of health and community services in Nunavik are discussed.
