The emerging cybersecurity industry in Canada is not seen as anywhere near the scale of its American cyber-industrial complex counterpart, with limited-scale projects occurring to improve security sensor technology for institutions. However, due to international trade increasingly occurring through cyberspace, it is expected that the cyber industry will grow in Canada through both international and domestic partnerships, with Canadian critical infrastructure partners requiring greater security controls in order to ensure the confidentiality, integrity and availability of their data and operations. 
Bringing To Light: Adversarial Poisoning Detection in Multi-controller Software-defined Networks
Authors: Das Tapadhir , Shukla Raj , Rath Suman , Sengupta Shamik
Published: May 2023

Machine learning (ML)-based network intrusion detection systems (NIDS) have become a contemporary approach to efficiently protect network communications from cyber attacks. However, ML models can become exploited by adversarial poisonings, like random label manipulation (RLM), which can compromise multi-controller software-defined network (MSDN) operations. In this paper, we develop the Trans-controller Adversarial Perturbation Detection (TAPD) framework for NIDS in multi-controller SDN setups. The detection framework takes advantage of the SDN architecture and focuses on the periodic transference of network intrusion detection models across the SDN controllers in the topology, and validates the models using the local datasets to calculate errors in their predictions with the ground truth. We demonstrate the efficacy of this framework in detecting RLM attacks in an MSDN setup. Results indicate efficient detection performance achieved by the TAPD framework in determining the presence of Random Label Manipulation attacks and the localization of the compromised controllers. We find that the framework works well even when there is a significant number of compromised agents in a large multi-controller setting. However, the performance begins to deteriorate when more than 40% of the SDN controllers in the MSDN have become compromised.

Published: May 2023

Visually impaired and blind people often face a range of socioeconomic problems that can make it difficult for them to live independently and participate fully in society. Advances in machine learning pave new venues to implement assistive devices for the visually impaired and blind. In this work, we combined image captioning and text-to-speech technologies to create an assistive device for the visually impaired and blind. Our system can provide the user with descriptive auditory feedback in the Kazakh language on a scene acquired in real-time by a head-mounted camera. The image captioning model for the Kazakh language provided satisfactory results in both quantitative metrics and subjective evaluation. Finally, experiments with a visually unimpaired blindfolded participant demonstrated the feasibility of our approach.
Semantic Segmentation of Foggy Scenes Based on Progressive Domain Gap Decoupling
Authors: Wang Ziquan , Zhang Yongsheng , Yu Ying , Zhang ZhenChao , Jiang Zhipeng , Cheng Binbin
Published: May 2023

Robust Semantic Foggy Scene Segmentation (SFSS) is crucial for the
security of autonomous driving. However, the blurring of images caused
by fog increases the difficulty of recognition and makes annotation of
foggy scene images more expensive, resulting poor performance when
recognizing entities in the fog. Currently, many methods use domain
adaptation to transfer segmentation knowledge from clear scenes to foggy
ones. But these method are often ineffective due to the large domain gap
between different cities’ styles and the quality degradation of images
caused by fog. The latest research has attempted to introduce an
intermediate domain to decouple the domain gap and gradually complete
the semantic segmentation of foggy scenes, but the exploration of the
intermediate domain information is often insufficient. To solve these
problems, we first analyze the self-training in domain adaptation and
propose the concept of “label reference value”. We prove that
the higher the total label reference value, the easier the self-training
performance gets improved. With this precondition, we can reasonably
split the original problem into two-stage domain adaptation. In each
stage, the “label reference value” can be controlled and
maximized. Specifically, the first stage only process the style gap
between source domain and the intermediate domain, and the second stage
process the fog gap. The fog gap includes: (1) real fog gap between the
intermediate domain and target domain; (2) the synthetic fog gap between
clear source domain and synthetic foggy source domain. This allows the
model to make full use of “label reference value” and gradually
develop good semantic segmentation skills for foggy scenes. Our approach
significantly outperforms the baseline algorithm on all the mainstream
SFSS benchmarks, with good generalization ability demonstrated in other
adverse scenes such as rain and snow. We also compare our method with
latest large segmentation models, which shows that our method has more
robust performance in the foggy scenes.

Objective: To evaluate the sensitivity of ultrasound in the diagnosis of nasal bone fracture in comparison with conventional X ray sensitivity.
Methodology: these patients were examined by conventional lateral nasal bone radiography followed by sonography without knowing the result of x-ray report and physical examination.
Results: In this study a 35 patients who had nasal bone fracture according to physical examination were investigated by sonography and radiography. Of these patients, 30 were men and 5 were women, with mean age of patients was 18.63 years. The current study revealed an x ray sensitivity approaching 60%, specificity was 86.7% respectively. While the results showed that ultrasonography sensitivity was 80%, specificity was 6.7% compared with clinical examination. The present study showed comparison of both tests that ultrasonography sensitivity was 80%, specificity was 6.7%, while x-ray was 60%, 86.7%. Also the results showed patients gender distribution of the nasal bone fracture with female and male percentage of 14.3% and 85.7% respectively. The results showed depending on trauma type domestic, RTA, and direct, the percentage rate was 34.3%, 11.4% and 54.3 % respectively. Also the results showed that frontal trauma associated with nasal bone fracture is 62.9% while a lateral trauma associated with nasal bone fracture is 37.1%.
Conclusions: Ultrasound is more sensitive test than x-rays in the diagnosis of nasal bone fracture and males are more exposed to nasal bone fracture than females with direct trauma is the predominant cause for nasal bone fracture.
Recommendation: Using ultrasound to confirm nasal bone fracture after clinical examination especially in children and pregnancy because it safer, cheaper, more sensitive and real time scan & to expanding the study to include follow up of patient after treatment.

Von willbrand syndrome remains a rare pathology. Its etiologies and clinical manifestations are varied. This syndrome can be inherited or acquired. The acquired form is associated with various pathologies (Gastric, mechanical support system…) including cardiovascular diseases such as aortic stenosis, HCM, and Mitral regurgitation. Nevertheless, the association of acquired Willebrand syndrome with coronary pathology remains a rare association. In this literature review, we have made a review of the various articles addressing this subject. The management of ACS in patients with AvWS follows that of normal patients in terms of interventional procedure, however therapeutic drug management remains delicate given the hemorrhagic risk that these drugs present. The use of DAPT and heparin is possible while thrombolysis remains at very high risk for the patient. The use of desmopressin can be done with caution and also factor VIII and vWF concentrates have their place to reduce the risk of bleeding. Overall, the collaboration of the cardiologist and hematologist remains essential for better management of these patients.

Published: May 2023

Synovial chondromatosis is a cartilaginous metaplasia of the residual stroma of the synovial tissue of the joint. Its main characteristic is the formation of cartilaginous nodules in the synovium and in the joint space (loose bodies). It usually appears between the ages of 30 and 50 and is rare in children. It presents as a monoarticular lesion affecting large joints such as the knee, hip and elbow, and rarely the ankle. The main symptoms are pain, swelling and limited mobility in the affected joints. Diagnosis is based on X-rays, CT scans and magnetic resonance imaging. In this case report, we describe a pediatric patient with synovial chondromatosis of the ankle. We discuss the imaging features on radiography, CT and MRI, followed by a brief review of the literature.

Published: May 2023

Summary: Chronic obstructive pulmonary disease is a slowly progressive chronic respiratory disease linked to smoking. Its evolution is marked by decompensation that can be life-threatening for the patient and thus require hospitalization in intensive care. The aim of our work is to describe the therapeutic management of patients hospitalized for decompensation of COPD and their clinical and etiological characteristics. The patients were all chronic smokers in 80% of cases with an average age of 62 years. Exacerbations were of infectious etiology in 76% with 43% bronchial superinfections and 33% pneumonia, and without identified cause in 15% of cases. Our patients were staged according to the GOLD classification. Stage 4 patients represented 63%, 56% had right heart failure and developed more exacerbations per year (4 on average) resulting in more hospitalization in intensive care (3 on average) while stage 3 patients represented 36% of all patients. Drug treatment was dominated by antibiotics, bronchodilators and corticosteroids. 80% of patients were on oxygen, 20% of whom were on long-term oxygen therapy. Ventilatory assistance was considered in 26% by means of non-invasive ventilation (NIV) and 16% required endotracheal intubation. In conclusion, decompensation of COPD alters the quality of life of patients and worsens the prognosis of COPD. According to the experience of our service, many therapeutic behaviors have been initiated by following international recommendations even if they remain controversial. However, a great effort is necessary, especially concerning the fight against tobacco.

The complete mandibular prosthesis constitutes a challenge for the practitioner. Unfavorable anatomo-physiological factors, including the small bearing surface and the extent of resorption, often compromise prosthetic retention. The exploitation of residual roots as a support for the conjunction bar constitutes an excellent additional mechanical means of retention. This prosthetic alternative considerably improves the comfort and masticatory coefficient of the patient on condition that the imperatives of root conservation as well as the clinical and laboratory implementation techniques are respected.
Outcome and Evaluation of Distal Tibial Close Fractures with Locking Compression Plate (LCP): A Prospective Study (MIPO) Approach
Authors: Hossain Md. Ismail , Alam Md. Insanul , Sagir Mohammad Golam , Rahman Md. Aminur , Hossain Md Younus
Published: May 2023

Background: Fractures of the distal tibia have historically proved difficult to treat. The distal tibia is less deeply covered by muscle and has a poorer blood supply. Therefore, problems are possible during the surgical treatment. We hope to evaluate the outcomes of LCP with minimally invasive plate osteosynthesis (MIPO) for the fixation of distal tibial fractures. Materials and Methods: A Multicentered based quasi-experimental prospective study was performed in 250 Beded District Hospital, Chapainawabganj, Rajshahi, Bangladesh, from January 2020 to December 2022. A Total Twenty-one patients were prospectively analyzed. Included were AO types 43A, 43B, and 43C. There were 21 patients (14 men and 7 women, with a mean age of 51). Results: The Mean time to union duration was 11 months (range, 3-35). There was a high perceived result for 17 fractures. The union of one patient was delayed. Nonunion, in one case, necessitated revision surgery, but the fracture healed with a satisfactory good functional outcome. Two patients had minor infections at the wound's surface, but their fractures subsequently healed. Conclusion: The MIPO procedure for the distal tibia has proven effective and offers many benefits over more traditional approaches. Stiffness and contracture can be avoided by early mobility without the potential of subsequent displacement.

Published: May 2023

Introduction: Optic nerve gliomas are rare tumors that are mainly observed in children. Exophthalmos and strabismus are the main signs of the disease. Neuroimaging and in particular magnetic resonance imaging is of great help in the diagnosis and follow-up of these tumors. The therapeutic management of these gliomas involves different means: surgical removal, chemotherapy, radiotherapy or abstention under surveillance. The indications must be discussed on a case-by-case basis. We report in this work a case of optic nerve glioma revealed by a strabismus and a unilateral exophthalmos. Case Report: This is a 3-year-old girl from a non-consanguineous marriage, with no specific pathological ATCD, who presented with divergent strabismus with left exophthalmos evolving for 3 months. The ophthalmologic examination noted a constant wide-angle divergent strabismus on the left eye with moderate exophthalmos on the same side. Corrected visual acuity was reduced to near finger count on the left and 5/10 on the right. Somatic examination found café au lait spots on the back and trunk. Cerebral CT showed a bilateral thickening of the optic nerves, fusiform and regular, more marked on the left, isodense to spontaneous contrast, homogeneously enhancing after injection of PDC. On the left, it is responsible for a downward refoulement of the eyeball with grade 1 exophthalmos. An MRI was ordered revealing a regular well-limited fusiform thickening of the optic nerves in T1 isosignal, intermediate in T2 and FLAIR, in diffusion hypersignal without ADC restriction, intensely and finely heterogeneous enhancing after injection of contrast medium. This thickening is responsible for a grade I left exophthalmos, with widening of the optic canals posteriorly and filling of the intraconical fat evoking a glioma appearance. The child was referred to neurosurgery for management. Conclusion: The diagnosis of optic nerve glioma in children is rare, with atypical presentations both in terms .........

Published: May 2023

Infective endocarditis is responsible of high intra-hospital morbidity and mortality rates. This can be explained partially by the diversity of its complications, which are often difficult to diagnose and manage therapeutically. We report the case of a 63-year-old woman, admitted to the intensive care unit for a sepsis due to infective endocarditis. On her second day of admission, she presented rapidly worsening paraparesis that leaded to flaccid paraplegia, for which she underwent a spinal MRI showing an extensive epidural abscess from T8 to T12 with spinal cord compression. The patient benefited from an emergency laminectomy, and the intraoperative bacteriological sample found the same germ isolated in the blood cultures (staphylococcus aureus methicillin sensitive). This case report emphasizes the importance of clinical and paraclinical evaluation of patients with infective endocarditis, in order to detect complications as early as possible, because if unnoticed, their management become very delicate.

Published: May 2023

The supply of hydroponic nutrients needs to consider economic, practical and resource saving aspects. It is necessary to know the best composition and type of nutrients that can be used in a hydroponic system. The use of liquid organic fertilizers (POC) as an alternative to hydroponic nutrients, especially in the wick system, has already begun including widely available alternative fertilizers such as NPK + Gandasil and utilizing chicken feather waste that has been made in the form of fertilizer. This research is expected to provide an overview of the potential for alternative nutrient sources for hydroponic growing media by utilizing the available resources. The study was started from June to August 2020, using a single randomized block design (RBD) consisting of 5 (five) treatment levels, namely: K0 = AB mix (control) 50 ml / 10 L water, K10 = 10 g NPK + 5g Gandasil / 10L water. K11 = 1/2 dose of Abmix + ½ dose of NPK + Gandasil, K12 = ½ dose of NPK + Gandasil + 4800ml / POC of chicken feathers / 10L of water, K13 = 1/2 dose of Abmix + 4800ml / POC of chicken feathers / 10L of water. The results showed that the type of nutrient media composition had no significant effect on plant height in weeks 1,2,3 and 4, leaf length weeks 1 and 2 and number of leaves weeks 1,2,3 and 4.

The variation in soil permeability levels as a result of several types of land use on dry land in Aceh Besar district is not widely known. Therefore, a study of the ability of soil to pass water (soil permeability) as a result of various land use patterns is very important to conduct research in order to maintain a sustainable environment. The metode of research used is directly survey method. The Field survey carried out by taking soil samples that were taken in a composite manner in the processing layer (0-20 cm) and intact. The variables measured include: permeability, soil organic fraction. Intact soil sampling is carried out using a ring or tube to determine soil permeability based on the constan head method. Meanwhile, composite soil samples, which are samples collected from several observation points mixed evenly into a homogeneous sample, those were used to variable soil organic fraction content using the pipette method. Permeability in the type of land use forest shrubs, mixed gardens, moor and teak forests were classified into the medium class. The order of increasing permeability starts from the type of land use for forest shrubs, mixed gardens, moorlands, teak forests and rainfed rice fields. Permeability rates didn't have correlation with organic matter content in several types of dry land use in Aceh Besar district. By increasing sand content, the pores between particles increase, the capillary action weakens, and water easily evaporates through the macro pores, or directly penetrate deep into the soil for vegetation use By increasing clay content, the effect of soil on local rainfall redistribution on vegetation growth changes from decreasing to increasing whereas sand, on the other hand, those was based on a limited distribution of soil types only with high clay content

Weeds are unwanted wild plants because they can interfere with the main crop cultivation. This study aims to identify and analyze the diversity of weed vegetation that grows around mango trees. This study uses the quadratic method with diagonal observation points and direct exploration techniques. Observation parameters include the type of weed and its population. Then the results of the observations were analyzed using the formula of Important Value Index (INP), Summed Dominance Ratio (SDR), Diversity Index (H'), Index of Similarity (IS), and Dominance Index (C). After doing the research, found 24 species of weeds consisting of broadleaf weeds, puzzles and grasses. The highest SDR value in Tondowulan Village was Cynodon dactylon L. at 13.82%, while in Darurejo Village it was Oplismenus hirtellus (L.) P. Beauv. by 26.53%. Weed diversity was classified as moderate because the weed diversity index value in Darurejo Village was 1.92% while in Tondowulan Village it was 2.31%. The two research locations did not have the same composition of weeds because the similarity value was only 33.33%. There is no weed species that dominates the mango garden because the index value of the weed dominance in Tondowulan and Darurejo Villages in the order of the 3rd largest is less than one.

Authors: Arridho Subhan
Published: May 2023

This study aims to determine the effect of the pre-emergence application of the herbicide metsulfuron methyl on the soil mixed with rice husk biochar to the germination of weeds. This study used a factorial completely randomized design (CRD) with two levels of herbicide metsulfuron methyl (0 gr/ha and 300 gr/ha) and four levels of rice husk biochar (0%, 5%, 10%, and 15% of the total weight of the planting medium). The parameters observed were the number of weeds, wet weight of weeds, and dry weight of weeds. The results showed that the interaction of the herbicide metsulfuron methyl and rice husk biochar had no significant effect on weed germination. The single treatment of the herbicide metsulfuron methyl had a significant effect on the number of weeds, wet weight of weeds, and dry weight of weeds. Herbicides can reduce the number of germinated weeds, wet weight of weeds, and dry weight of weeds by 39.3%, 83.7%, and 84.7%, respectively. While the single treatment of rice husk biochar showed a significant effect on the number of weeds and dry weight of weeds. The 15% treatment of rice husk biochar was the best to reduce the number of germinated weeds, namely 76.6%.

This study aimed at examining the analysis of the soil quality index of dry land use on dry land in Blang Bintang District, Aceh Besar District. This research was conducted using a descriptive method based on the results of surveys and field observations as well as laboratory analysis. General biophysical conditions of the area and physical and chemical characteristics of the soil obtained from observations and indicators of soil quality through soil analysis in the laboratory. Soil sampling points were determined using the purposive sampling method, namely the points that have been determined on selected dry land in Blang Bintang District, Regency of Aceh Besar. The moderate soil quality index in the upland land use type is one of the reasons for the sampling of the Inceptisol soil type in the Blang Bintang sub-district, which has less fertile soil characteristics. Upland land use is the percentage of sand (57%) which is greater than the percentage of dust (36%) and clay (6%). This can be seen in the low content of C-organic (1.19), H2O, K-dd, P-available and N-total and high volume weight (1.34).
