Adaptive denoising of ECG using EMD, EEMD and CEEMDAN signal processing techniques
Authors: Teja Krishna , Tiwari Rahul , Mohanty Satish 
Published: December 2020

Abstract
Using adaptive signal processing techniques denoising of ECG signal is performed which is obtained from physionet database. In this paper, the baseline wandering noise is removed using different adaptive techniques such as Empirical Mode Decomposition (EMD), Ensemble Empirical Mode Decomposition (EEMD) and Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN). All these algorithms are effectively used to decompose the noisy ECG signal into different Intrinsic Mode Functions (IMFs) and further these IMFs are filtered using low pass filtering method to extract the low frequency baseline component. The high frequency noise present in the reconstructed signal is reduced by further decomposing into IMFs using all the three methods. These IMFs are soft thresholded to remove the high frequency noise. The results obtained from the CEEMDAN outperform EMD and EEMD in extracting signal from noise. Further, distinct parameters such as skewnesscrest factor, RMS value and kurtosis are estimated for the reconstructed signal to analyse their behaviour.
Methods for removal of artifacts from EEG signal: A review
Authors: Kotte Shailaja , Kumar Dabbakuti J R K 
Published: December 2020

Abstract
Electroencephalogram (EEG)is the record of cerebral activity, the electric potential of cerebral activity is of low amplitude, and less frequency ranges between 4 to 60 Hz, which can easily mix up different non-cerebral signals and other environmental noise signals. The extraction of actual cerebral signals from the contaminated EEG signal is the major challenge in medical analysis. Somehow, during the recording of the EEG signal, contamination of other signals takes place, which increases complexity in analyzing the accurate EEG signal. This leads to inaccurate information signals in the analysis. Accordingly, the process to eliminate the unwanted signals in the pre-processing level is mandatory in brain signal analysis. The unwanted signals from various sources are together termed as artifacts; the researchers have implemented various techniques to reduce the undesired signals. However, still, there is no standard technique in detecting and eliminating the artifacts, and hence, the research became most challenging.

Published: December 2020

AbstractIn this paper, a method is proposed to differentiate the classes such as Bleeding and Polyps between the many classes present in GI tract using efficient classification model. The challenge in all image analysis is to characterize these images which improve the exact detection of these abnormalities. To solve this problem, a Center-Symmetric Local Binary Pattern (CS-LBP) feature extraction with Random Forest (RF) and Support Vector Machine (SVM) methods are employed to classify these two classes. Our model shows an excellent detection accuracy of 90.39 for polyps and 94.85for bleeding respectively for the CS-LBP with RF and SVM.

Abstract
Of late, concrete technology is changing at a fast phase. Concrete is a flexible material and several attempts are being made to incorporate different materials specially industrial wastes as substitutes to the existing ingredients to enhance the quality of concrete. On the other hand environmentally sustainable concrete is in great demand. As plastic waste disposal has become a major problem for the modern day society, concrete has played a vital role as a dumping material. Plastic can either be used in concrete either as a partial substitute for fine aggregate or as an additive.Plastic wastes are present in different forms. This study focuses on use of waste Nylon Cable Ties (NCT) as a partial replacement of fine aggregates (1%, 2%, 4%) and as addition (0.5%, 1%, 1.5%) for M40 grade of concrete. Different tests like flexural, split tension, compression,effects of temperature and permeability test are being carried out. It was observed that 2% replacement of M-sand by waste NCT gives better results compared to 1% and 4% replacement of waste NCT. Addition of 1% NCT gives maximum compression, spilt tensile strength and flexural strength in concrete. When compared to replacement of fine aggregates by waste NCT, addition of waste NCT is found to give better strength.The permeability of the specimens was reduced for both replacement and addition of NCT ties. However permeability was found to be lesser for addition of NCT ties. But the performance of these specimens was not very satisfactory for either replacement or addition of NCT ties.
Multi-walled carbon nano-tubes for enhancing the performance of cementitious composites
Authors: Zaheer Mohd Moonis , Jafri Mohd Shamsuddin , Varisha  
Published: December 2020

Abstract
Due to exceptional properties, multi-walled carbon nano-tubes (MWCNTs) are designated as a promising reinforcing material for the nano-modified cementitious composites. The performance of cementitious composites with MWCNTs on the mechanical, durability, and microstructure properties was investigated in this study. The MWCNTs were effectively dispersed by the sonication method using high-frequency ultrasonic waves. The flexural strength, compressive strength, density, porosity, and stress-strain curves of cementitious composites reinforced with different concentrations (0.1, 0.2, 0.3, 0.4, and 0.5 wt%) of MWCNTs were studied. The enhanced flexural and compressive strength demonstrates the exceptional reinforcing behaviour of the MWCNTs. Additionally, density outcome indicates that as the percentage of MWCNTs in the matrix increases, density increases, and the optimum content was obtained as 0.3 wt%. The pores of cementitious composites can be reduced by adding carbon nano-tubes, which was perceived through a microstructural study using SEM micrographs. Study outcomes establish that in addition to the advantages provided by the nano-tube reinforcement in augmenting strength, nano-tubes can also help in reducing the porosity of the composites. The effectiveness of this promising nanomaterial related to its field application is also highlighted.

Published: December 2020

Abstract
Mass gathering in places such as shopping mall, concerts, sport events etc. is a necessity but may pose threat to the occupants during emergency. This paper presents a review of the different approaches of the crowd evacuation problems which can be classified into classical and modern methods. The classical methods have been widely used which basically depends on prior evacuation warnings or human in assisting an emergent evacuation scenario. Nonetheless, with the lack of important information such as the location of the safest exit, the consequence can be catastrophic. As a result, classical evacuation method becomes tough even though many people might able to assist the evacuees during such situation. Overcoming this, researchers have developed intelligent robots-assisted evacuation systems as a modern approach to manage crowds more systematically and simultaneously during emergency, which will be reviewed in this paper. Finally, this review paper aims to give a broad scope of the reliable evacuation system management to ensure the safety of the evacuees during emergency evacuation.

Soft tissue vibration: a biologically-inspired mechanism for stabilizing bipedal locomotion
Authors: Masters Samuel E , Challis John H 
Published: December 2020

Abstract
Humans are made up of mostly soft tissue that vibrates during locomotion. This vibration has been shown to store and dissipate energy during locomotion. However, the effects of soft tissue vibration (wobbling masses) on the dynamics of bipedal walking have not been assessed in terms of stability. Given that much of the human body is vibrating just following foot-ground contact, it may have dynamic implications on the stability of walking. A rigid bipedal walker and a bipedal walker with soft tissue were simulated to quantify the effects of soft tissue vibration on gait periodicity, orbital stability, global stability, and robustness to uneven terrain. It was found that moderate amounts of energy dissipation resulted in much more stable walking dynamics relative to that of a rigid bipedal walker.
Structural diversity of random aggregates of identical spheres
Authors: Blétry Marc 
Published: December 2020

Abstract
Random aggregates of hard spheres can be formed either by aggregation or by dynamic reorganization. The resulting two broad families of aggregates present different geometrical structures that have not been studied in a systematic fashion to this day. We investigate various structural indicators (contact coordination number, Delaunay tetrahedra, Voronoi polyhedra, pair distribution functions,…) of aggregates belonging to these two broad families, building them by using Lubachevsky–Stillinger algorithm for the aggregates formed by dynamic reorganization and a family of aggregation algorithms. This comparison takes place over a large range of packing fraction, from 0.370 up to 0.640. This allows distinguishing significant differences between random aggregates formed by aggregation or in a dynamic manner, or according to the contacting status of the spheres. Various structural commonalities are also investigated by different structural indicators. An evaluation of the parameters that could distinguish between all studied aggregates is also proposed.
The evolution of summary procedure in investment arbitration: past, present and future
Authors: Ba Duong Donny Trinh 
Published: December 2020

Abstract
The last 15 years have witnessed a substantial rise of summary procedure to gradually become more and more significant in the world of investment arbitration since ICSID Arbitration Rules first introduced it in 2006. Before the emergence of this procedure that allows early dismissal of claims, various states have criticized the time and costs needed to defend their position in investment proceedings. Against this background, the birth of summary procedure aims to help parties to save time and costs and avoid unnecessary consumption of parties’ resources by disposing of manifestly frivolous and unmeritorious at an early stage of the proceedings. This feature has captured much attention since major arbitration institutions started to adopt it, with ICSID being the pioneer, followed by the Singapore International Arbitration Centre (SIAC) and the Arbitration Institute of the Stockholm Chamber of Commerce (SCC). Given its increasing importance in investment disputes, the ICSID has lately published a series of Working Papers which, among many other things, proposed to enhance the rule on ‘manifest lack of legal merit’. This article aims to look back on the evolution of summary procedure in investment arbitration for the last 15 years by examining its genesis and development, the current regime, and tribunals’ application of this procedure in practice, the future contemplated by the ICSID proposed amendments.
Asymptomatic Stroke After Hyaluronic Acid Filler Injection: Case Report and Literature Review
Authors: Moore Ryan M , Mueller Melissa A , Hu Allison C , Evans Gregory R D 
Published: December 2020

Abstract

Vascular compromise and blindness are reported but rare complications of facial soft tissue filler injections. Stroke is an even rarer complication resulting from intraarterial injection of fillers. We present a case of a patient suffering all 3 complications following hyaluronic acid filler injection: forehead skin vascular compromise, unilateral blindness, and ipsilateral subclinical strokes. Were it not for a stroke workup protocol, the incidental strokes may have otherwise gone undetected, suggesting the incidence of stroke from intraarterial injection may be higher than reported. Further, we review the literature and recommendations for prevention and management of threatened tissue ischemia and vision loss from facial filler injection.

Published: December 2020

Abstract
The prognostic role of adjacent nontumor tissue in hepatocellular carcinoma (HCC) patients is still not clear. The activity changes of immunologic and hallmark gene sets in adjacent nontumor tissues may substantially impact on prognosis by affecting proliferation of liver cells and colonization of circulating tumor cells after HCC treatment measures such as hepatectomy. We aimed to identify HCC subtypes and prognostic gene sets based on the activity changes of gene sets in tumor and nontumor tissues, to improve patient outcomes. We comprehensively revealed the activity changes of immunologic and hallmark gene sets in HCC and nontumor samples by gene set variation analysis (GSVA), and identified three clinically relevant subtypes of HCC by nonnegative matrix factorization method (NMF). Patients with subtype 1 had good overall survival, whereas those with subtype 2 and subtype 3 had poor prognosis. Patients with subtype 1 in the validation group also tended to live longer. We also identified three prognostic gene sets in tumor and four prognostic gene sets in nontumor by least absolute shrinkage and selection operator method (LASSO). Interestingly, functional enrichment analysis revealed that in nontumor tissues, genes from four gene sets correlated with immune reaction, cell adhesion, whereas in tumor tissue, genes from three gene sets closely correlated with cell cycle. Our results offer new insights on accurately evaluating prognosis—the important role of gene sets in both tumor and adjacent nontumor tissues, suggesting that when selecting for HCC treatment modality, changes in tumor and nontumor tissues should also be considered, especially after hepatectomy.

Published: December 2020

Abstract

Background
We identified host single-nucleotide variants (SNVs) associated with neurocognitive impairment (NCI) in perinatally HIV-infected (PHIV) children.

Methods
Whole-exome sequencing (WES) was performed on 217 PHIV with cognitive score for age (CSA) &lt; 70 and 247 CSA ≥ 70 (discovery cohort [DC]). SNVs identified in DC were evaluated in 2 validation cohorts (VC). Logistic regression was used to estimate adjusted odds ratios (ORs) for NCI. A human microglia NLRP3 inflammasome assay characterized the role of identified genes.

Results
Twenty-nine SNVs in 24 genes reaching P ≤ .002 and OR ≥ 1.5 comparing CSA &lt; 70 to CSA ≥ 70 were identified in the DC, of which 3 SNVs were identified in VCs for further study. Combining the 3 cohorts, SNV in CCRL2 (rs3204849) was associated with decreased odds of NCI (P &lt; .0001); RETREG1/FAM134B (rs61733811) and YWHAH (rs73884247) were associated with increased risk of NCI (P &lt; .0001 and P &lt; .001, respectively). Knockdown of CCRL2 led to decreased microglial release of IL-1β following exposure to ssRNA40 while knockdown of RETREG1 and YWHAH resulted in increased IL-1β release.

Conclusions
Using WES and 2 VCs, and gene silencing of microglia we identified 3 genetic variants associated with NCI and inflammation in HIV-infected children.

AbstractThe egg parasitoid Trichogramma spp. (Hymenoptera: Trichogrammatidae) is a widely used biocontrol agent against lepidopteran pests. Historically, Trichogramma were deployed either by plane or by using cardboard cards on which parasitized eggs are glued and manually installed at sites. Plane deployment is costly and card installation is time consuming, but the use of Trichogramma has been shown to be efficient against several pests. In 2016 and 2017, a research project investigated the potential use of unmanned aerial system for distributing Trichogramma as biocontrol agents against two major pests: an agricultural pest of maize, the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), and a forest pest, the eastern spruce budworm, Choristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae). Exposure duration of parasitized eggs to field conditions (temperature, predation, etc.) in maize fields influenced the Trichogramma’s emergence rate, suggesting that timing of parasitoid releases with their emergence is essential. Although parasitism of naturally occurring eggs in maize fields could not be compared due to the low density of the European corn borer, parasitism of sentinel eggs by Trichogramma was more prominent in plots with unmanned aircraft systems (UAS)-releases compared to control plots. For spruce budworm, treatment with Trichogramma increased egg parasitism and there was no difference between the deployment by UAS and by Trichocards. We discuss these results in the context of pest biology and management. We also discuss the advantages and shortcomings of both methods and offer insights into where future work might go to further leverage the use of UAS in managing these important pests.
Equality in the Informed Consent Process: Competence to Consent, Substitute Decision-Making, and Discrimination of Persons with Mental Disorders
Authors: Scholten Matthé , Gather Jakov , Vollmann Jochen 
Published: December 2020

AbstractAccording to what we propose to call “the competence model,” competence is a necessary condition for valid informed consent. If a person is not competent to make a treatment decision, the decision must be made by a substitute decision-maker on her behalf. Recent reports of various United Nations human rights bodies claim that article 12 of the Convention on the Rights of Persons with Disabilities involves a wholesale rejection of this model, regardless of whether the model is based on a status, outcome, or functional approach to competence. The alleged rationale of this rejection is that denying persons the right to make their own treatment decisions based on an assessment of competence necessarily discriminates against persons with mental disorders. Based on a philosophical account of the nature of discrimination, we argue that a version of the competence model that combines supported decision-making with a functional approach to competence does not discriminate against persons with mental disorders. Furthermore, we argue that status- and outcome-based versions of the competence model are discriminatory.

Published: December 2020

Abstract

Objective
The objective was to explore family caregivers’ perspectives of the recovery process of older adults with hip fracture and describe experiences from caregivers who: (1) used the online intervention, or (2) received home-based care provided by the Andalusian Public Health Care System.

Methods
This was an exploratory secondary study with informal family caregivers who had an older adult family member with hip fracture enrolled in a novel telerehabilitation (telerehab) clinical trial. Forty-four caregivers of older adults with hip fracture were interviewed at 6 to 9 months after their family member’s hip fracture.

Results
Caregivers shared concerns of family members’ survival and recovery; they recounted increased stress and anxiety due to the uncertainty of new tasks associated with providing care and the impact on their lifestyle. Although most caregivers were satisfied with the health care received, they made suggestions for better organization of hospital discharge and requests for home support. The main reasons why caregivers and their family member chose the telerehab program were to enhance recovery after fracture, gain knowledge for managing at home, and because of the convenience of completing the exercises at home. There were more family caregivers in the control group who expressed a high level of stress and anxiety, and they also requested more social and health services compared with caregivers whose family member received telerehab.

Conclusion
Family caregivers are an essential component of recovery after hip fracture by providing emotional and physical support. However, future clinical interventions should evaluate person-centered interventions to mitigate possible stress and anxiety experienced by family caregivers.

Impact
Family caregivers’ perspectives are necessary in the co-design of management strategies for older adults after hip fracture.
