Hybrid basis vector based underdetermined beamforming algorithm in optimized antenna reconfiguration
Authors: R. Krupa Prasad K. , Maheshappa H. D.
Published: October 2021

Optimized positioning of antenna to obtain the best beam forming solution is adopted in this research. Non-uniform linear array-based beamforming algorithms have the challenge of placing the array of antennas in positions that would implement best beamforming outputs. This paper attempts to obtain the optimized beam forming by tuning the sparse Bayesian learning based algorithm. The parameters used for tuning involve choosing the hybrid basis vector for creating the steering vector while at the same time developing the optimized position of the antennas. Basis vectors are the building blocks of the steering vector developed for the beamforming algorithm that finds the angle of arrival in antennas. Reconfiguration of antennas is carried out using particle swarm optimization (PSO) algorithm and the basis vectors are generated using two different ways. One by cumulating similar basis vectors and another by cumulating two different basis vectors. The performance of accurate detection of angle of arrival in the beamforming algorithm is analyzed and results are discussed. This basis vector and antenna distance optimization is adopted on the sparse Bayesian learning paradigm. Performance evaluation of these optimizations in the algorithm is realised by validating the mean square error (MSE) versus signal to noise ratio (SNR) graphs for both the cumulative basis vector and hybrid basis vector cases.

Published: October 2021

COVID-19 pandemic, despite its devastating impact, accelerated the shift to e-learning in higher education. Particularly in the electrical machines courses, that often include laboratory experiments. However, no detailed models of transformers, developed in Simulink/MATLAB®, were reported in the literature. Hence, in this paper, a virtual laboratory consists of models of single-phase transformers was built for the first time. The proposed models are easy to use and modify, and allow all machines’ parameters to be altered for students to replicate easily to support and enhance the learning process of electrical machines courses. Consequently, the developed models are effective tools for educational and research purposes. Dynamic models of single-phase, two-winding, transformers and step-up and step-down auto-transformers were developed using Simulink/MATLAB®. Two different approaches for modelling were proposed, the block diagram representation and Simscape based models. The two modelling methods were validated against the built-in transformer model. The developed models have been successfully integrated into electrical engineering courses at Middle Technical University, Baghdad, Iraq. Therefore, all developed models are freely available online at a dedicated repository.

Published: October 2021

The pest namely coffee white stem borer (CWSB) has harmed the economic progress of many emerging countries as a result of arabica coffee’s agricultural products. The boring activity causes the stem to shrink, fade in color, and acquire translucent margins across the stem. The pest multiplier can be controlled by capturing the location with the utilization of a wireless sensor networks (WSNs) and blocking its exit point at the user end. In this work, we propose an integrated data aggregation with faulttolerance and lifetime energy-aware adaptive routing (IDALAR) approach to transfer the sensed pest location data. The efficient packet format and statistical models based routing between clusterheads (CHs) and base station (BS) is proposed considering the availability of resources such as message overhead, algorithmic complexity, residual energy, and control overhead are all used to calculate its performance.

Authors: Cárdenas-Lancheros Esteban Alejandro , Vera-Parra Nelson Enrique
Published: October 2021

Internet of things (IoT) and artificial intelligence provide more and more solutions to the exercise of capturing data effectively, taking them through processing and analysis stages to extract valuable information. Currently, technological tools are applied to counteract incidents in motorcycle driving, whether they are part of the same vehicle or are externally involved in the environment. Incidents in motorcycle driving are increasing due to the demand for the acquisition of these vehicles, which makes it important to generate an approach towards reducing the risk of road accidents based on the analysis of dynamic behavior while driving. The development of this research began with the detection and storage of data associated with the dynamic acceleration variable of a motorcycle while driving, this with the help of a 3-axis accelerometer sensor generating a dataset, which was processed and analyzed for later be taken by three predictive classification models based on machine learning which were decision trees, K-Nearest neighbors and random forests. The performance of each model was evaluated in the task of better classifying the level of accident risk, concerning the driving style based on certain levels of acceleration. The random forest model showed a slightly better performance compared to that shown by the other two models, with 97.24% accuracy and recall, 97.16% precision and 97.17% F1 score.
The security of RC4 algorithm using keys generation depending on user's retina
Authors: Salih Huda M. , Mahdawi Raghda Salam Al
Published: October 2021

Digital technologies grow more rapidly; information security threats are becoming increasingly dangerous. Advanced and various cyber-attacks and security threats, like targeted emails, and information exploitation, pose a critical threat that basically undermines our trust in the digital society. Rivest cipher 4 (RC4) algorithm is a significant cipher of a stream that could be utilized with protocols of the internet, the advantage of the RC4 algorithm is that it is simple and effective. There are several weak, especially after the pseudo-random generation algorithm (PRGA), PRGA's initially 256 rounds (the amount of the RC4 permutation). Several modified RC4 studies have been published thus far, however, they all face either standard privacy or achievement evaluation issues. This paper proposes a new RC4 algorithm that is based on the user's retina (RC4-Retina), which has solved both of these weak points it was indicated in the standard RC4 algorithm. The novelty of retina key scheduling algorithm (RKSA), which is generated by relying on the user's retina of the algorithm will modify the matrix of permutation used to configure the keys. The efficiency of the improved algorithm was measured by depending on the average security of ciphertext of different keys and different messages, results were good compared to the standard algorithm.
Portable gas leak detection system using IoT and off-the shelf sensor node
Authors: Al-Jemeli Marwan Ihsan Shukur , Al-Adilee Maythem Kamal Abbas
Published: October 2021

In companies that use toxic gases in vast amounts for a range of procedures, there are a host of high-risk concerns to address. People will not be able to track or control the emission of these gases on a routine basis until it becomes harmful. Sensors are expected to actively detect leaks and alert users to any potential hazards. Gas leakage may occur at multiple locations within a single installation. As a result, sensors are implanted as close to the suspected leak site as possible, enabling them to track leakage and relay signals to a base station that is situated far away. Many sensor values are received and analyzed using a microcontroller. The generated data is encoded in the wireless module and sent to the base through the internet of things link, where it is decoded and viewed by another microcontroller. When leaks are detected, the device sends an audio and visual alert, and since the detection period is very limited due to high-speed processing, leakage situations are brought under control with minimal or no effect. Using the new IoT technology and tracking from anywhere on the network, this project offers a cost-effective and reliable solution for mitigating leakage risk.
An improved Kohonen self-organizing map clustering algorithm for high-dimensional data sets
Authors: Begum Momotaz , Das Bimal Chandra , Hossain Md. Zakir , Saha Antu , Papry Khaleda Akther
Published: October 2021

Manipulating high-dimensional data is a major research challenge in the ﬁeld of computer science in recent years. To classify this data, a lot of clustering algorithms have already been proposed. Kohonen self-organizing map (KSOM) is one of them. However, this algorithm has some drawbacks like overlapping clusters and non-linear separability problems. Therefore, in this paper, we propose an improved KSOM (I-KSOM) to reduce the problems that measures distances among objects using EISEN Cosine correlation formula. So far as we know, no previous work has used EISEN Cosine correlation distance measurements to classify high-dimensional data sets. To the robustness of the proposed KSOM, we carry out the experiments on several popular datasets like Iris, Seeds, Glass, Vertebral column, and Wisconsin breast cancer data sets. Our proposed algorithm shows better result compared to the existing original KSOM and another modiﬁed KSOM in terms of predictive performance with topographic and quantization error.

Published: October 2021

The world is now faced with a devastating pandemic outbreak coronavirus disease-2019 (COVID-19). The latest coronavirus infected almost all continents and witnessed sharp rises in cases diagnosed. The engineers tend to eliminate the matter and have solutions, one in every utilizing technical innovation. Researchers from Singapore, Taiwan, and Denmark have developed a fully automated robot that may take coronavirus swabs in order for health care professionals don’t seem to be exposed to the chance of infection. The objective of this study is to present the potential effects of robotics to help healthcare professionals on getting specimens and testing for COVID-19. These possible consequences include positive and negative outcomes and as a result, the overall impact on the profit or loss to society is far from obvious. The paper discusses two theoretical scenarios, distinguished fundamentally by the different behavioral responses of the automated swab robot and the selection of results in line with policy interventions.

Outcomes of Venoarterial Extracorporeal Membrane Oxygenation for Cardiac Arrest in Adult Patients in the United States
Authors: Gill George , Patel Jignesh K. , Casali Diego , Rowe Georgina , Meng Hongdao , Megna Dominick , Chikwe Joanna , Parikh Puja B.
Published: October 2021

Background

Factors associated with poor prognosis following receipt of extracorporeal membrane oxygenation (ECMO) in adults with cardiac arrest remain unclear. We aimed to identify predictors of mortality in adults with cardiac arrest receiving ECMO in a nationally representative sample.

Methods and Results

The US Healthcare Cost and Utilization Project's National Inpatient Sample was used to identify 782 adults hospitalized with cardiac arrest who received ECMO between 2006 and 2014. The primary outcome of interest was all‐cause in‐hospital mortality. Factors associated with mortality were analyzed using multivariable logistic regression. The overall in‐hospital mortality rate was 60.4% (n=472). Patients who died were older and more often men, of non‐White race, and with lower household income than those surviving to discharge. In the risk‐adjusted analysis, independent predictors of mortality included older age, male sex, lower annual income, absence of ventricular arrhythmia, absence of percutaneous coronary intervention, and presence of therapeutic hypothermia.

Conclusions

Demographic and therapeutic factors are independently associated with mortality in patients with cardiac arrest receiving ECMO. Identification of which patients with cardiac arrest may receive the utmost benefit from ECMO may aid with decision‐making regarding its implementation. Larger‐scale studies are warranted to assess the appropriate candidates for ECMO in cardiac arrest.
The Aesthetics of In/Authenticity: Buddhism, Commodification, and Ethnoreligious Belonging in a Sino-Tibetan Contact Zone
Authors: Brox Trine
Published: October 2021

This article investigates how the cultural politics of ethnoreligious belonging play out through everyday aesthetic practices at a market for Tibetan Buddhist objects in Chengdu, China – a multiethnic place that is perceived and experienced as “Tibetan” by the Tibetans and Chinese who work, live, and shop there. Based upon ethnographic research in Chengdu, I explore how Tibetan urbanites navigate the sensorially intense market, sorting its sights, sounds, and smells to determine who and what belongs as authentically Tibetan Buddhist. In the process, I argue, they are laying claim to an ability to feel the in/authentic acquired through being born and raised as a Tibetan. This practical ability is what I call an aesthetic habitus. Yet, many Tibetans fear this ability is being eroded; it is no longer clear who and what belongs, contributing to anxieties that Tibetans as a distinct ethnoreligious community will be extinguished.
Beethoven and Buddhism in a Japanese Religion: Culture as Cultivation in Soka Gakkai
Authors: McLaughlin Levi
Published: October 2021

Why is the museum at the headquarters of the lay Japanese Buddhist organization Soka Gakkai full of pianos? How did Gakkai members in Japan come to revere the compositions and ethos of Ludwig van Beethoven as means of defending Buddhist orthodoxy? And how did this Buddhist organization come to rely on classical music as a key form of self-cultivation and institution building? This article draws on ethnographic engagements with musicians in Soka Gakkai, along with study of the Gakkai’s development in 20th-century Japan, to detail how practitioners’ Buddho-cultural pursuits demonstrate ways cultural practices can create religion. Attention to Soka Gakkai’s fusions of European high culture with lay Buddhist teachings and practices troubles static definitions of “Buddhism” and signals the need for broader inquiry into the nature of religious belonging through investigations of aesthetic forms.
Philosophical Perspectives on Eunomia
Authors: Bartels Myrthe L.
Published: October 2021

This contribution analyses the ancient Greek notion of eunomia in the philosophical prose literature of the fourth century BC. While the term eunomia is often translated as ‘good government’ or ‘good order’, such vague translations fail to capture the specifics of eunomia, and thus part of the philosophical debate about constitutions is lost. Closer inspection reveals that within the fourth-century constitutional debate, eunomia entails two distinct aspects: the excellence of the laws and their durability. These two aspects are predicated of various constitutions: the mixed constitution, of which Sparta and Crete are primary examples in the fourth century; the Athenian democracy as a paradigm of law-abidingness; and philosophical constitutions aiming at virtue. It is a hallmark of the last that such law codes start from marriage and childbirth and follow the course of human life.
The Stoic Conception of Law
Authors: Vogt Katja Maria
Published: October 2021

The Stoics identify the law with the active principle, which is corporeal, pervades the universe, individuates each part of the world, and causes all its movements. At the same time, the law is normative for all reasoners. The very same law shapes the movements of the cosmos and governs our actions. With this reconstruction of Stoic law, I depart from existing scholarship on whether Stoic law is a set of rules. The question of whether ethics involves a set of rules is rich and fascinating. In the 1970s and 80s, the observation that ancient ethics might do without rules was part of philosophy’s rediscovery of virtue ethics. This debate, however, neglects that Stoic law is a corporeal principle pervading the world. The key puzzle regarding Stoic law, I argue, is how it is possible that the very same law is a corporeal principle in the world and normative for us.
Pyrrhonism and the Value of Law
Authors: Marchand Stéphane
Published: October 2021

The aim of this paper is to determine how a Pyrrhonian (as she/he is described by Sextus Empiricus) considers the Law and can respond to Aristocles’ objection that a Pyrrhonian is unable to obey laws. First (1), we analyze the function of the Law in the 10th Mode of Aenesidemus, in order to show laws as a dogmatic source of value. But (2) Sextus shows also that the Sceptic can live in a human society by following laws and customs, according to so-called ‘sceptical conformism’. In the light of Pyrrhonian Hypotyposes (Pyr.) 1.23–24 and Against the Mathematicians (Math.) 11.162–164, I discuss the validity of the label ‘conformism’ in order to understand the nature of the political effect of the suspension of judgement. (3) The real nature of the political position of Pyrrhonian Scepticism – that lack of commitment does not mean indifference to politics but rather a criticism of fanaticism and praise for political cautiousness – appears by comparison with the Scepticism of the New Academy.
Varro, the Name-Givers, and the Lawgivers: The Case of the Consuls
Authors: Arena Valentina
Published: October 2021

This essay aims at identifying a tradition of lawgivers in the political culture of the late Republic. It focuses on the antiquarian tradition of the second half of the first century BC, which, it argues, should be considered part of the wider quest for legal normativism that takes place towards the end of the Republic. By reconstructing the intellectual debates on the nature of the consulship, which at the time was carried out through the means of etymological research, this essay shows that, when set within its proper philosophical framework, ancient etymological studies acted as a search for philosophical truth and, in the case of Varro, identify the early kings as the first Roman lawgivers. In turn, the language of political institutions and its etymologies, conceived along philosophical lines, could become a weapon in the constitutional battles of the late Republic.
Application of Muslim Family Law as a Form of Customary Law in Accra, Ghana
Authors: Issaka-Toure Fulera
Published: October 2021

This article examines the central role of the malam (Islamic scholar) in the application of Muslim family law in a legal plural tradition in Accra, Ghana. It demonstrates that the role of the malam as a legal actor is one which is not self-ascribed, yet his deployment of such role is significant in how we understand the interaction of various bodies of laws and their hierarchies. The article shows that women form the majority of the litigants who seek to improve their wellbeing by appealing to Islamic legal norms through the malamai. It argues that, through the judicial practices of the malamai of the two dominant Islamic groups, the Tijāniyya and the Salafiyya, the manner in which the malam himself deploys his legal role reveals how his position is relevant for his predominantly female clients. In the end, this article contributes to how we understand the practice of legal pluralism through the application of Muslim family law as a form of customary law.
Mosaic, block-face microscopy for measuring cell dimensions, cell collapse, and spatial relationships in wood
Authors: Dickson Alan
Published: October 2021

A conventional stereo light microscope was used to image polished wood surfaces at cellular resolution over size scales of the growth ring or larger. Bandpass filtering and local area contrast enhancement were used to aid automatic image thresholding and binarisation. An estimate for the location and proportion of cell collapse was introduced based on the distance between uncollapsed cell lumens. Additionally, spatial associations between vessels were determined using a Euclidean distance transform. The analysis of pith to bark cores provided sufficient detail to show significant intra and inter-annual trends in Pinus radiata tracheid dimensions (wall thickness, wall area, and radial widths). These trends were consistent with expectations and in agreement with the literature. Measured cell dimensions may be influenced by cell collapse and deformation as a result of drying. The analysis of air, kiln and oven-dried Eucalyptus nitens showed that cell collapse was highly variable but generally more prominent in the outer third of growth rings. There were significant changes in vessel shape across the growth rings and vessel area was significantly reduced by drying. The technique provides an intermediate step between detailed microscopy and macroscopic imaging that allows spatial analysis at the wood cell level.

Published: October 2021

Two novel cyanobacteria (AP3 and AP3b) with thin cells and simple morphology were isolated from two islands of the Indian Sundarbans.  The 16S rRNA phylogeny data revealed the distinct lineage of AP3b which was nearest to the clade incorporating the genus Oculatella and Tildeniella.  Strain AP3 shared a common ancestor with the species Euryhalinema mangrovii.  Additionally, the novel 16S rRNA gene sequences of strains AP3 and AP3b showed similarities about 98% and 93% respectively compared to those of established genera or species to which they were phylogenetically related.  Furthermore, the folding patterns of semi-conservative structures like D1-D1’, Box-B and V2 helices of 16S-23S ITS region for both strains AP3 and AP3b displayed significant variations and uniqueness when compared with their respective reference strains (Euryhalinema mangrovii for AP3 and all the genera of Oculatellaceae for AP3b).  Strain AP3 shared similar morphological features with its reference strain which confirmed its inter-species relationship.  The diagnostic features of AP3b including the presence of necridic cells, aerotopes and a cluster-like growth pattern were found to be very contrasting.  Altogether, these results substantiated the establishment of strain AP3b as a novel mono-specific genus named Aerofilum fasciculatum and strain AP3 as the second novel species under the genus Euryhalinema, referred to as Euryhalinema pallustris.

Published: October 2021

We here describe two new species Arachniodes libingii and A. vietnamensis (Dryopteridaceae) from southern China and central Vietnam, respectively. Our previous phylogenetic analysis found a close relationship between the two new species. Further morphological studies showed that the two species share short creeping rhizomes, blackish brown and lanceolate scales, papery laminae, aristate pinnules, dense scales along fronds, and entire indusia. However, A. libingii has deltoid-oblong laminae and apices abruptly acuminate-caudate, while A. vietnamensis has shortly ovate laminae and apices gradually acuminate.
On some deep-sea Stenheliinae from the Gulf of California and the west coast of the Baja California Peninsula (Mexico): the genus Delavalia Brady, 1869 and proposal of Archaeohuysia gen. nov. and Diarthropodella gen. nov. (Copepoda: Harpacticoida: Miraciidae)
Authors: GÓMEZ SAMUEL
Published: October 2021

Several species belonging to the harpacticoid families Ameiridae Boeck, Ancorabolidae Sars, Argestidae Por, and Rhizothrichidae Por have been described so far as an ongoing long-term project on the diversity of deep-sea benthic harpacticoids collected from the Gulf of California and Mexican Pacific. Amongst the several harpacticoid taxa, the subfamily Stenheliinae Brady (Miraciidae Dana) showed to be one of the most important components to overall species richness in deep-sea sediments. Following the rejection of segmentation pattern of the first swimming leg as the only discriminant for subgeneric assignment of stenheliin taxa, four new species of Delavalia Brady, 1869 and two new genera, Archaeohuysia gen. nov. and Diarthropodella gen. nov. are proposed herein. The new Delavalia species belong to the longicaudata-group with close relatives in shallow-water habitats. The so far monotypic Archaeohuysia gen. nov. showed to be unique in the combination of the general structure of the first swimming leg and retention of the primitive complement of four setae on the second endopodal segment of the same leg. Diarthropodella gen. nov. is the only stenheliin taxon with a two-segmented exopod of the first swimming leg. Some comments are given on probable multiple colonization events of stenheliin taxa.
Two new marine cyclopinids (Crustacea: Copepoda: Cyclopoida) from interstitial habitats in Korea
Authors: KARANOVIC TOMISLAV
Published: October 2021

Marine cyclopoids, and especially cyclopinids, are poorly studied because their diversity is highest in marginal habitats, such as intertidal interstitial and anchialine caves, or in highly inaccessible abyssal and hadal depths. Two new cyclopinids are described here, both from two different sandy beaches in Korea. Among four species currently recognized in the genus, Heterocyclopina koreaensis sp. nov. is most closely related to H. vietnamensis Pleşa, 1969 from similar habitats in Vietnam. Koreacyclopina wellsi gen. et sp. nov. shares its sexually dimorphic third exopodal segment of the second leg with the Antarctic genus Pseudocyclopina Lang, 1946, but differs from all six known species by numerous features, some of which are observed for the first time within cyclopinids. Both Korean species belong to the family Hemicyclopinidae, but the monophyly of this group has not yet been demonstrated.
New records of Pseudotachidiidae from South Korea, including a key to species of the Pseudomesochrinae (Copepoda: Harpacticoida)
Authors: KIM JONG GUK , LEE JIMIN , HUYS RONY
Published: October 2021

Two species of the marine harpacticoid family Pseudotachidiidae (Copepoda) are reported from subtidal sediments in the Southern Sea of Korea. Psammis wellsi sp. nov. (Danielsseniinae) is most closely related to P. longisetosa Sars, 1910 but differs from its European congener in the ventral ornamentation of the female genital double-somite, the dorsal ornamentation of the second abdominal somite in the male, the armature of the proximal endite of the maxillary syncoxa, the relative setal lengths and general shape of the female P5, and the relative length of the inner seta of the male P5 endopodal lobe and P6. The female of Pseudomesochra tatianae Drzycimski, 1968 is redescribed in detail, constituting the only other record of the species since its discovery at the type locality in western Norway. East Asian records of members of the four subfamilies currently recognized in the Pseudotachidiidae are summarized. Published and other records of the 23 described species in the Pseudomesochrinae are collated and their armature patterns of P1–P5 are tabulated and corrected where necessary. Pseudomesochra affinis (Sars, 1920) is removed from its synonymy with P. longifurcata T. Scott, 1902 and formally reinstated as a valid species. An updated female-based key to the 19 valid species of Pseudomesochra T. Scott, 1902 and four species of Keraia Willen & Dittmar, 2009 is presented.
Description of a new species of Nannopus Brady, 1880 (Copepoda: Harpacticoida: Nannopodidae) from Argentinean waters, including an updated key to species
Authors: SCIBERRAS MICHEL , CAZZANIGA NÉSTOR J. , HUYS RONY
Published: October 2021

Both sexes of a new brackish-water species, Nannopus sinusalbi sp. nov. (Nannopodidae) are described from the Bahía Blanca estuary (38°53’S, 62°07’W) in Buenos Aires Province, Argentina. The only previous record of the genus in the study area was identified as the type species, Nannopus palustris Brady, 1880, with no description or illustrations, hence its authenticity cannot be confirmed. Nannopus brasiliensis Jakobi, 1956 is relegated to species inquirenda in the genus rather than being considered a junior synonym of the type species. Nomenclatural issues related to the usage of the alternative spellings Iliophilus Lilljeborg, 1902 and Ilyophilus sensu Sars (1909) and the unavailability of Ilyophilus canui Kim, Choi & Yoon, 2017 are discussed. An updated key to the 18 identifiable species of Nannopus (excluding the type species N. palustris) is presented. The harpacticoid assemblage at the type locality showed a distinct seasonality with N. sinusalbi sp. nov. representing about 8% of the community. The new species showed densities below 5 ind.cm‑2 during most of the year, reaching an abrupt peak of 40.17 ind.cm‑2 towards the end of the summer, when the maximum proportion of ovigerous females was recorded.
Two rare species of Danielsseniinae (Copepoda: Harpacticoida: Pseudotachidiidae) from the Kara and East Siberian Seas, with description of their previously unknown sexes
Authors: GARLITSKA LESYA , CHERTOPRUD ELENA S.
Published: October 2021

The previously unknown females of Danielssenia spitsbergensis Gee & Huys, 1994 and males of Mucrosenia kendalli Gee & Huys, 1994 (Pseudotachidiidae, Danielsseniinae) are described based on specimens collected in the Kara and East Siberian Seas.

                Females of D. spitsbergensis exhibit the main diagnostic features of the genus Danielssenia Boeck, 1873 (antennule four-segmented; proximal segment of antennary exopod with one seta; structure of all the mouthparts; absence of an inner seta on exopod-1 of P2–P4; P5 not fused medially and with distinct exopod and baseoendopod, the latter with five setae; genital field with small copulatory pore and short copulatory duct leading to seminal receptacle with paired anterior chambers). At the same time, these specimens also exhibit some distinctive features which are unique for the species but disagree with the generic diagnosis. These peculiarities validate the placing of D. spitsbergensis as species incertae sedis within Danielssenia and point out the necessity of examination of other ‘Danielssenia-like’ forms before the true taxonomic position of this species can be elucidated.

                Both males and females of M. kendalli exhibit the autapomorphies of the genus, viz. P2 endopod-2 with a mucroniform process reaching almost to end of endopod-3 (this sexually dimorphic character is more pronounced in the males but also present in females); P2 endopod-2 without inner seta; posterior displacement of caudal ramus seta II; presence of tuft of long setules at inner distal corner of caudal ramus; P2 endopod shorter than exopod; P2–P4 exopod-1 without inner seta. Furthermore, some particular features (anal somite and pseudoperculum morphology; female P1 endopod distinctly longer than exopod; P5 exopod with distinct suture on dorsal surface separating it from the baseoendopod; prominent mucroniform process on P2 endopod-2) of the Kara and East Siberian Sea specimens conform fully with the original description of M. kendalli but apparently differ from M. kliei (Smirnov, 1946), the single female of which was collected from the same region and depth. Therefore, the validity and definite status of the specimen described by Smirnov is still a matter of conjecture pending additional findings and, particularly, the discovery of the male.
A “Participatory School” in Iran: A Bottom-Up Learning Approach in a Top-Down Education System
Authors: Manouchehri Bahar , Burns Edgar A.
Published: October 2021

This article discusses how a bottom-up approach to learning can be positioned within a top-down educational structure. For the first time, Iran’s educational system has witnessed a shift from a one-dimensional teacher-centered approach to the triangular student-facilitator-parent approach. While the majority of children’s participative activities in Iran have pedagogical functions, the participatory type of school was established to prioritize the voice of students. Through an analysis of interviews in a study of participatory schooling in Iran, this research identified several similarities and contradictions in terms of children’s inclusion between the theoretical framework and philosophy of democratic and child-centered school with the conventional Iranian one. The contribution of this article is to highlight how the socio-political features of the context can influence the structure and approach to education and effectiveness of inclusion. This approach to learning can be significant in societies where child integration has not yet found its meaningful position in schools.
A Comparison of IHEs and Non-IHEs as Anchor Institutions and Lead Agents of Promise Neighborhoods Projects
Authors: Impellizeri Whitney , Lee Vera J.
Published: October 2021

Place-based initiatives, such as the federal Promise Neighborhoods grant, attempt to coordinate interventions, supports, and services with a myriad of organizations to targeted communities. Although Institutions of Higher Education (IHEs), inclusive of academic medical institutions, are among the most overall researched anchor institution, Non-Institutions of Higher Education (NIHEs) have led more Promise Neighborhood grants since the inception of the program in 2010. Therefore, this study compared the revitalization efforts proposed by IHEs ( n = 5) and NIHE ( n = 5) in their applications for Promise Neighborhoods grants awarded between 2016 and 2018. Although similarities existed within and across the applications from NIHEs and IHEs, namely focused on improving academics and health/wellness, the specific interventions, supports, and services proposed by each lead institution largely reflected the individual needs of the targeted communities. The findings from this study illustrate how IHEs and NIHEs are similarly positioned to effectuate change within their communities. Implementing place-based initiatives requires anchor institutions to allocate considerable time and resources in order to adapt to the current needs of the community in real time. Therefore, future lead agents of Promise Neighborhoods should seek to promote an environment that fosters on-going collaboration and mutual trust across and within multiple stakeholders, while also exploring sustainability efforts to extend gains made beyond the duration of the grant.

In this study, the artificial neural network was deployed to develop a classification model for predicting the class of a drug-related suspect into either the drug peddler or non-drug peddler class. A dataset consisting of 262 observations on drug suspects and offenders in central Nigeria was used to train the model which uses parameters such as exhibit type, suspect’s age, exhibit weight, and suspect’s gender to predict the class of a suspect, with a predictive accuracy of 83%. The model sets the pace for the implementation of a full system for use at airports, seaports, police stations, and by security agents concerned with drug-related matters. The accurate classification of suspects and offenders will ensure a faster and correct reference to the sections of the drug law that correspond to a particular offence for appropriate actions such as prosecution or rehabilitation.
Neighbourhood selection and neighbourhood matching: Choices, outcomes and social distance
Authors: Clark William A. V. , Ong ViforJ Rachel , Truong N. T. Khuong
Published: October 2021

In this article, we ask how well Australian households are matched to their neighbourhood social environments. We broadly replicate a previous study of matching and ask to what extent households live in communities that are similar in socio-economic status to their characteristics. And, when households move, do they relocate in such a way as to increase similarity to their neighbours? The processes are at the heart of understanding the urban structure, how it changes over time and the links to urban inequality. The article uses data on household incomes from the Household, Income and Labour Dynamic (HILDA) Survey to measure the degree of similarity between households and their neighbours. We study the variation in matching for the population as a whole, and by quintiles of median neighbourhood income. We also measure how individuals that change neighbourhoods increase their similarity to the destination neighbourhood. We find that with respect to matching there is considerable diversity in the levels of matching; and that with respect to residential change, households in general do not make major shifts to increase matching when we control for housing tenure and other household characteristics. There is a need for further replications to understand the nature of matching and the outcomes.

Objectives:

Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared with conventional CPR. Data after eCPR for acute kidney injury (AKI) are lacking. We sought to investigate factors predicting AKI in patients who underwent eCPR.

Methods:

From January 2016 until December 2020, patients who underwent eCPR at our institution were retrospectively analyzed and divided into two groups: patients who developed AKI ( n = 60) and patients who did not develop AKI ( n = 35) and analyzed for outcome parameters.

Results:

Overall, 63% of patients suffered AKI after eCPR and 45% of patients who developed AKI needed subsequent dialysis. Patients who developed AKI showed higher values of creatinine (1.1 mg/dL vs 1.5 mg/dL, p ⩽ 0.01), urea (34 mg/dL vs 42 mg/dL, p = 0.04), CK (creatine kinase) (923 U/L vs 1707 U/L, p = 0.07) on admission, and CK after 24 hours of ECMO support (1705 U/L vs 4430 U/L, p = 0.01). ECMO explantation was significantly more often performed in patients who suffered AKI (24% vs 48%, p = 0.01). In-hospital mortality (86% vs 70%; p = 0.07) did not differ significantly.

Conclusion:

Patients after eCPR are at high risk for AKI, comparable to those after conventional CPR. Baseline urea levels predict the development of AKI during the hospital stay.
A bathymetric mapping and SLAM dataset with high-precision ground truth for marine robotics
Authors: Krasnosky Kristopher , Roman Christopher , Casagrande David
Published: October 2021

In recent years, sonar systems for surface and underwater vehicles have increased in resolution and become significantly less expensive. As such, these systems are viable at a wide range of price points and are appropriate for a broad set of applications on surface and underwater vehicles. However, to take full advantage of these high-resolution sensors for seafloor mapping tasks an adequate navigation solution is also required. In GPS-denied environments this usually necessitates a simultaneous localization and mapping (SLAM) technique to maintain good accuracy with minimal error accumulation. Acoustic positioning systems such as ultra short baseline (USBL) and long baseline (LBL) are sometimes deployed to provide additional bounds on the navigation solution, but the positional uncertainty of these systems is often much greater than the resolution of modern multibeam or interferometric side scan sonars. As such, subsurface vehicles often lack the means to adequately ground-truth navigation solutions and the resulting bathymetic maps. In this article, we present a dataset with four separate surveys designed to test bathymetric SLAM algorithms using two modern sonars, typical underwater vehicle navigation sensors, and high-precision (2 cm horizontal, 10 cm vertical) real-time kinematic (RTK) GPS ground truth. In addition, these data can be used to refine and improve other aspects of multibeam sonar mapping such as ray-tracing, gridding techniques, and time-varying attitude corrections.
Incorporating Quaternary Prevention: Understanding the Full Scope of Public Health Practices in Sexual Abuse Prevention
Authors: McCartan Kieran , Kemshall Hazel
Published: October 2021

This discussion piece argues for a refinement in our understanding of prevention in sexual abuse, suggesting that we include quaternary prevention on the grounds that this concept from medical literature has potential and helpful application to criminal justice and particularly to work with those who cause sexual harm. Located within the paradigm of Epidemiological Criminology (EpiCrim), quaternary prevention extends the prevention spectrum to enable a stronger distinction between tertiary level responses and long-term safe, sustainable reintegration into communities, particularly of those who sexually abuse others. The key principles of quaternary prevention are adapted and refined from current medical literature, and the potential usefulness of quaternary prevention to crime and sex abuse prevention is explored.

Published: October 2021

Biodegradable poly(butylene adipate-co-terephthalate)/poly(lactic acid) (PBAT/PLA) composites were prepared by melt blending, and chain extender was used to improve the compatibility of PBAT/PLA blends through the chemical reaction. The influence of PLA and chain extender contents on mechanical properties, morphology, and rheological properties of PBAT/PLA composites was systematically investigated. The results revealed that the Young’s modulus and stress values gradually increased under the same strain, whereas the elongation at break decreased with the increase of chain extender content for PBAT/PLA (80/20) composites. Noteworthy, the presence of chain extender improves the interfacial compatibility between PLA and PBAT phases. At the chain extender content of 0.4, 0.6, and 0.8 wt.%, the extensional viscosity of the composites exhibited an increasing trend, whereas an obvious strain-hardening phenomenon emerged in the uniaxial extensional curves.
The effect of boric acid on flame retardancy of intumescent flame retardant polypropylene composites including nanoclay
Authors: Demirhan Yasin , Yurtseven Recep , Usta Nazım
Published: October 2021

In this study, different amounts of boric acid (BA, 1.25, 2.5, 3.75 and 5.0 wt%) were used to enhance the effectiveness of an intumescent flame retardant (IFR) system composed of ammonium polyphosphate (APP) and pentaerythritol (PER) in polypropylene (PP) including 2 wt% montmorillonite nanoclay (MMT). Meanwhile, metaboric acid and boron oxide which were generated by the decomposition of BA appeared in the melt compounding and the burning processes, respectively. Extensive experimental studies were performed to investigate the effects of BA/boron oxide and MMT combinations on the properties of PP/IFR. The fire resistances of the composites were studied by UL 94, limiting oxygen index (LOI) and cone calorimetry tests. The thermal properties were determined by using thermogravimetric analysis, differential scanning calorimetry and thermal conductivity measurements. In addition, the mechanical properties of the composites were examined. The experimental results revealed that although the additions of 1.25 and 2.5 wt% BA with 2 wt% MMT significantly enhanced thermal and flame resistances of PP composites, 3.75 and 5.0 wt% BA additions generated antagonistic effects and deteriorated the fire resistance of the composites. The sample including 2.5 wt% BA addition achieved the best flame retardancy. The LOI value was increased from 18 to 31% with UL 94 V-0 rating. In addition, the peak heat release rate was reduced from 668.6 to 150.0 kW/m2 and the total heat release value was decreased from 247.9 to 98.4 MJ/m2. In the meantime, the thermal conductivity was increased from 0.22 up to 0.28 W/mK. Furthermore, CO, CO2 and the smoke productions were significantly decreased with respect to PP. NO generation was decreased with BA replacements. At the same time, although there was a slight decrease in the tensile strength, the flexural strength significantly increased with BA and MMT additions.
