Rare earth elements (REEs) are widely attracting global attention due to their crucial role in the modern lifestyle, especially in the industrial advancement towards a green economy through renewable technologies. This particular group of metals consists of the 15 lanthanides, yttrium (Y), and scandium (Sc). There are two subgroups, namely light rare earth elements (LREEs) from lanthanum (La) to europium (Eu) and heavy rare earth elements (HREEs) from gadolinium (Gd) to lutetium (Lu) and Y (Fig. 1a). Generally, LREEs are more abundant in the mineral deposits when compared to more priced HREEs [1].

The repaid generation of e-Waste in the Sri Lanka urban context has the potential to support the national circular economy. The generation of e-waste is unavoidable in the rapidly developing technology sector. E-waste is typically perceived as a burden. The recycling and recycling and reusing of e-waste can positively influence the circular economy. E-waste has the properties such as recyclability and can be used to recover valuable metal components that are depleting rapidly. Comprehensive investigations have been carried out on the public perception of e-waste reusability and its challenges and limitation as a new business model. The study outcomes can help determine how people’s (the consumers’) perceptions can be effectively assessed to develop a sustainable business model that can be effectively employed to manage e-waste.

Authors:   Department of Transport and Logistics Management, University of Moratuwa, Sri Lanka, Herath Erandi , Sivakumar Thillaiampalam ,   Department of Transport and Logistics Management, University of Moratuwa, Sri Lanka
Published: October 2022

Even-though Public Transport (PT) was the most common (60%) mode of transport in Sri Lanka, people are shifting from PT to private vehicles during last few years. That has created a significant traffic congestion on roads which is one of the critical issues in urban roads in Sri Lanka. Improving PT service quality and promoting PT among people would be one solution. The existing service quality of PT should be identified first and expected improvements should be captured. Many researchers have identified “Level of Service (LOS)” as an efficient tool to measure PT service quality [1]. Transit Capacity and Quality of Service Manual highlights the importance of user’s perception for determining level of service [2]. This research attempt to quantify the existing LOS of PT based on bus passengers’ opinion gathered through a questionnaire survey from route between Galle to Colombo. From the literature review, the study identified around 15 factors which affect the LOS of PT and incorporated them into the survey.
Resection of an occipital lobe epileptogenic network resulting in improvement of a visual field deficit: illustrative case
Authors: Dincer Alper , Herendeen John , Oster Joel , Kryzanski James
Published: October 2022

BACKGROUND

Drug-resistant epilepsy leads to significant morbidity and mortality. Epilepsy surgery for resection of seizure foci is underused, particularly when a seizure focus is located in eloquent cortex. Epileptogenic networks may lead to neurological deficits out of proportion to a causative lesion. Disruption of the network may lead not only to seizure freedom but also reversal of a neurological deficit.

OBSERVATIONS

A 32-year-old male with new-onset generalized tonic-clonic seizure was found to have an occipital lobe cavernous malformation. On visual field testing, he was found to have a right-sided hemianopsia. He did not tolerate antiepileptic drugs and had a significant decline in quality of life. Resection was planned using intraoperative electrocorticography to remove the cavernous malformation and disrupt the epileptogenic network. Immediate and delayed postoperative visual field testing demonstrated improvement of the visual field deficit, with near resolution of the deficit 6 weeks postoperatively.

LESSONS

Epilepsy networks in eloquent cortex may cause deficits that improve after the causative lesion is resected and the network disrupted, a concept that is underreported in the literature. A subset of patients with frequent epileptiform activity and preoperative deficits may experience postoperative neurological improvement along with relief of seizures.

Authors: Ravina Kristine , Windermere Sonora A. , Zhao Qing , Lerner Adam , Dyer Michael , Upadhyay Urvashi , Jha R. Tushar
Published: October 2022

BACKGROUND

Primary extraosseous intracranial Ewing’s sarcoma, also known as a peripheral primitive neuroectodermal tumor or “small round blue cell tumor,” is an extremely rare entity with limited representation in the literature beyond the pediatric population.

OBSERVATIONS

A 67-year-old male suffering occipital headache, nausea, and gait disturbance was found to have a large, avidly contrast-enhancing cerebellopontine angle mass extending into the cervical spinal canal with associated mass effect on medulla, cerebellum, fourth ventricle, and cervical spinal cord. This mass was not present on the imaging from 8 years prior. He underwent surgical debulking and pathology results demonstrated a malignant small round cell tumor showing diffuse immunopositivity for cytokeratins, CD99 and NKX2.2 with EWRS1-FLI1 rearrangement in 84% of the nuclei confirmatory of Ewing’s sarcoma. After 14 cycles of chemotherapy and 6 weeks of radiotherapy, 22 months after discovery, the patient remains in clinical and radiographic remission with complete return to his baseline functioning.

LESSONS

Primary skull base extraosseous Ewing’s sarcoma should be considered in the differential diagnosis even in the elderly population when imaging studies demonstrate aggressive tumor growth patterns. Tumor debulking to establish a diagnosis followed by adjuvant chemoradiation therapy can result in clinical improvement with remission.
Endoscope-assisted far lateral craniotomy for resection of posterior fossa neurocysticercosis: illustrative case
Authors: Fang Jerrell , Banerjee Christopher , Barrett Amanda , Gilbert Bruce C. , Rutkowski Martin J.
Published: October 2022

BACKGROUND

Neurocysticercosis is a parasitic infection that commonly affects the ventricles, subarachnoid spaces, and spinal cord of the central nervous system. The authors report an unusual manifestation of purely posterior fossa neurocysticercosis treated with endoscope-assisted open craniotomy for resection.

OBSERVATIONS

A 67-year-old male presented with 2 months of progressive dizziness, gait ataxia, headaches, decreased hearing, and memory impairment. Imaging revealed an extra-axial cystic lesion occupying the foramen magnum and left cerebellopontine angle with significant mass effect and evidence of early hydrocephalus. Gross-total resection was accomplished via a left far lateral craniotomy with open endoscopic assistance, and pathological findings were consistent with neurocysticercosis. Postoperatively, he was noted to have a sixth nerve palsy, and adjuvant therapy included albendazole. By 9 months postoperatively, he exhibited complete resolution of an immediate postoperative sixth nerve palsy in addition to all preoperative symptoms. His hydrocephalus resolved and did not require permanent cerebrospinal fluid (CSF) diversion.

LESSONS

When combined with traditional skull base approaches, open endoscopic techniques allow for enhanced visualization and resection of complex lesions otherwise inaccessible under the microscope alone. Recognition and obliteration of central nervous system neurocysticercosis can facilitate excellent neurological recovery without the need for CSF diversion.

A number of specialized dairy breeds of intensive type have been created in Ukraine, among which the Ukrainian black-and-white dairy farm occupies a prominent place. Currently, the improvement of this breed is carried out by using various breeding techniques with a focus on achieving maximum milk productivity of cows, improving milk quality, body type, health, stress resistance and prolonging productive longevity.
The aim of the research was to investigate the formation of signs of milk productivity of cows depending on the origin of the father and the country of his selection.
The researches have been conducted on bred heifers and mature cows (third lactation) of Ukrainian Black-and-White dairy breed in the State Enterprise "Alexandrovske" in Vinnytsia region. The traits of milk productivity (yields, fat content in milk and quantity of milk fat ) were studied for the last 10 years by retrospective analysis of bred heifers and mature cows (3-rd lactation), theoretically substantiated and proven feasibility of the study variability of these traits and their intergroup differentiation depending on the father’s origin and the countries of its selection, the consideration and application of which in the selection process will support creating of highly productive competitive herds of dairy cattle. The research showed the great influence of the origin of the father and the country of its selection on the variability of milk yield, fat content in milk and cows’ milk fat yield.
It was found that the cows of the controlled herd were characterized by quite high indicators of milk productivity: the yields of bred heifers – 6115, mature cows - 6899 kg. The descendants of the bull Jorin 114414759 were the most productive during the first lactation (milk yield - 6936 kg, milk fat - 248.9 kg), and for the third - the daughters of the breeder Detective 349159846 (8148 and 295.2 kg respectively). The descendants of breeding bulls of German selection gave the most milk and milk fat quantity for the studied lactations (6269- 7014 and 224.8-250.3 kg, respectively). At the same time, the daughters of Canadian breeders gave the most fat- milk yield for the first lactation (3.66%), and for the third lactation – the daughters of the Dutch bulls (3.59%).
Breeding bulls had a more significant influence on the traits of milk productivity (depending on lactation 13.1-31.8%), the country of their selection – much smaller (0.9-11.9%). In this regard, these factors had the greatest impact on milk yields, and the least - on the fat content in milk.

Розглянуто метод декларативного метапрограмування, який орієнтований на генеруввання коду. Метод базується на розширенні синтаксису розповсюджених мов програмування загального призначення. Розширення синтаксису доповнює оригінальний синтаксис мови, надаючи додатковий функціонал генерування коду за допомогою використання шаблонів. Шаблон містить точну структуру отриманого згенерованого коду, але дозволяє вказувати деталі для кожного згенерованого фрагмента. Метод додає нові елементи синтаксису, які дозволяють змінювати контексти під час написання програми, що генерує код. Зовнішній контекст виконується миттєво під час компіляції програми. Внутрішній контекст містить код шаблону, який буде згенеровано. Головне — забезпечити плавний перехід між двома контекстами, щоб код усередині кожного з них був написаний за допомогою однієї мови програмування. Метод забезпечує два типи генерування коду, а саме: миттєве та відкладене генерування. Перший створює згенерований код миттєво під час компіляції. Другий дозволяє генерувати код під час виконання програми. У цьому випадку він генерує проміжне подання шаблону у вигляді публічної функції, яку можна викликати під час виконання програми. Щоб забезпечити належний досвід використання такого підходу, важливо реалізувати інтеграцію з інтегрованим середовищем розробки, яке включає підсвічування коду та перевірку синтаксису. Крім того, коректна інтеграція може бути забезпечена шляхом розробки плагіна для систем збірки Bazel або Gradle.

Published: October 2022

In a recent work we introduced a problem about finding the highest polarized bipartition on a weighted and labeled graph that represents a debate developed trough some social network, where nodes represent user’s opinions and edges agreement or disagreement between users. Finding this target bipartition is an optimization problem that can be seen as a generalization of the maxcut problem, so we first introduced a basic local search algorithm to find approximate solutions of the problem. In this paper we go one step further, and we present an exact algorithm for finding the optimal solution, based on an integer programming formulation, and compare the performance of a new variant of our local search algorithm with the exact algorithm. Our results show that at least on real instances of the problem, obtained from Reddit debates, the approximate solutions obtained are almost always identical to the optimal solutions.

Cities are becoming data-driven, re-engineering their processes to adapt to dynamically changing needs. A.I. brings new capabilities, effectively enlarging the space of policy interventions that can be explored and applied. Therefore, new tools are needed to augment our capacity to traverse this space and find adequate policy interventions. Digital twins are revealing themselves as powerful tools for policy experimentation and exploration, allowing faster and more complete explorations while avoiding costly interventions. However, they face some problems, among them data availability and model scalability. We introduce a digital twin framework based on an A.I. and a synthetic data model on NO2 pollution as a proof-of-concept, showing that this approach is feasible for policy evaluation and (autonomous) intervention and solves the problems of data scarcity and model scalability while enabling city level Open Innovation.
Bootstrap-CURE Clustering: An Investigation of Impact of Shrinking on Clustering Performance
Authors: Karna Ashutosh , Gibert Karina
Published: October 2022

Hierarchical clustering is one of the most popular techniques in unsupervised segmentation. However, since it has quadratic complexity as it is based on pairwise distance matrix construction, it tends to be less used with really large data cases. CURE clustering tackles this challenge by accelerating the process through a first hierarchical clustering over a smaller sample from which a set of representative points of resulting clusters is obtained and used to estimate the cluster shape. A KNN process with those representative points allows completing the cluster assignment to the remaining points. This clustering technique scales the hierarchical clustering to large datasets. This work is in continuation of the earlier research, Bootstrap-CURE which uses repeated samples in the first part of the process and gains both robustness and representativeness. Also, the proposed approach uses a criterion for automatic identification of the number of clusters from a dendrogram, so that the bootstrap samples can be automatically processed. In this paper, the concept of shrinkage is proposed as a hyperparameter to the Bootstrap-CURE clustering approach. The inclusion of shrinkage brings the proposed clustering technique closer to the original CURE clustering. The impact of shrinkage on the overall performance of Bootstrap-CURE is further explored. A real-life use case from 3D printers is presented to illustrate the performance of the proposed clustering.

The cumulus-oocyte complex (COC) is an oocyte surrounded by specialized granulosa cells, called cumulus cells. The cumulus cells surrounding the oocyte ensure healthy oocyte and embryo development. The maturity of COCs at oocyte retrieval may be used as an indicator to predict outcome of assisted reproductive technology (ART). Segmenting COCs is a preliminary step in many image processing pipelines to evaluate maturity. However, acquiring well-annotated bright-field microscopy image datasets remains a time-consuming and inaccurate procedure, for most biological domains. Additionally, specialists often partially disagree on their annotations, not only among each other, but also among their own annotations, leading to an inconsistent outcome. Despite the recent advancements in deep learning and image segmentation tools for biological and biomedical images, there is limited usage of them for having more accurate and automated procedures. In this work, we propose an automated pipeline to segment bovine COCs in bright-field microscopy images. The results of our evaluation show that our pipeline is able to segment COCs with the same level of quality as provided by human experts.

Published: October 2022

Diabetic retinopathy (DR) is one of the most common causes of vision loss or blindness globally. Early detection of retinal eye lesions like hard exudates, soft exudates, microaneurysms, and hemorrhages is crucial to detect DR in a human eye. Therefore, accurate segmentation of lesions from eye fundus images is essential to develop efficient automated DR detection systems. This paper presented a novel hard and soft exudates lesions segmentation method called Efficient Dual-Decoder Boosted Network (EDBNet). EDBNet is composed of the following main components: 1) pre-trained ImageNet ResNet50 encoder with Atrous Spatial Pyramid Pooling (ASPP), 2) UNet decoder block with Gated Skip Connections mechanism to enhance capture more details of fundus images, 3) dual-decoder boosted to improve the performance segmentation of retinal lesion in the eye fundus images, and fusion outputs of the dual-decoder boosted to generate enhanced exudates segmentation. The effectiveness of the proposed framework is assessed on the IDRiD publicly dataset in terms of accuracy, Area Under Precision-Recall (AUPR), IOU, and Dice metrics. EDBNet obtains 99.8, 74.4, 78.0, and 87.6% of soft exudates, respectively. For hard exudates, EDBNet achieves 99.5, 85.3, 80.3, and 89.1%, respectively. The experimental results also demonstrate that EDBNet outperforms many state-of-the-art methods.
Fuzzy-LORE: A Method for Extracting Local and Counterfactual Explanations Using Fuzzy Decision Trees

Published: October 2022

Classification systems based Machine Learning hide the logic of their internal decision processes from the users. Hence, post-hoc explanations about their predictions are often required. This paper proposes Fuzzy-LORE, a method that generates local explanations for fuzzy-based Machine Learning systems. First, it learns a local fuzzy decision tree using a set of synthetic neighbours from the input instance. Then, it extracts from the logic of the fuzzy decision tree a meaningful explanation consisting of a set of decision rules (which explain the reasons behind the decision), a set of counterfactual rules (which inform of small changes in the instance’s features that would lead to a different outcome), and finally a set of specific counterfactual examples. Our experiments on a real-world medical dataset show that Fuzzy-LORE outperforms prior approaches and methods for generating local explanations.
Scenario Three: Chaos and Regional Anarchy

The third future sketched in this study is the ‘nightmare scenario’ with a number of countries in the south falling prey to third-state influence or collapsing outright. It implies that several interconnected crises from the fall of the regime in Saudi Arabia to the end of Khamenei’s rule in Iran provide a smokescreen for China and Russia’s expansion in the region. The first major question facing NATO is whether the Alliance would have the political and resource base to deal with multiple crises simultaneously. Secondly, given the role of hostile third powers in the scenario, NATO would have to consider how it could deter the creation of new naval bases or other military installations. Such a situation would necessitate early warning analyses by the Alliance and requires a strong focus on the interconnectivity of security, political, economic and environmental pressures in the region is certainly required.
