Orthogonal approach to independent component analysis using quaternionic factorization
Authors: Borowicz Adam 
Published: September 2020

AbstractIndependent component analysis (ICA) is a popular technique for demixing multichannel data. The performance of a typical ICA algorithm strongly depends on the presence of additive noise, the actual distribution of source signals, and the estimated number of non-Gaussian components. Often, a linear mixing model is assumed and source signals are extracted by data whitening followed by a sequence of plane (Jacobi) rotations. In this article, we develop a novel algorithm, based on the quaternionic factorization of rotation matrices and the Newton-Raphson iterative scheme. Unlike conventional rotational techniques such as the JADE algorithm, our method exploits 4×4 rotation matrices and uses approximate negentropy as a contrast function. Consequently, the proposed method can be adjusted to a given data distribution (e.g., super-Gaussians) by selecting a suitable non-linear function that approximates the negentropy. Compared to the widely used, the symmetric FastICA algorithm, the proposed method does not require an orthogonalization step and is more accurate in the presence of multiple Gaussian sources.
Secure neural network watermarking protocol against forging attack

Published: September 2020

AbstractIn order to protect the intellectual property of neural network, an owner may select a set of trigger samples and their corresponding labels to train a network, and prove the ownership by the trigger set without revealing the inner mechanism and parameters of the network. However, if an attacker is allowed to access the neural network, he can forge a matching relationship between fake trigger samples and fake labels to confuse the ownership. In this paper, we propose a novel neural network watermarking protocol against the forging attack. By introducing one-way hash function, the trigger samples used to prove ownership must form a one-way chain, and their labels are also assigned. By this way, an attacker without the right of network training is impossible to construct a chain of trigger samples or the matching relationship between the trigger samples and the assigned labels. Our experiments show that the proposed protocol can resist the watermark forgery without sacrificing the network performance.

Published: September 2020

AbstractThe increasing reliance on electronic health record (EHR) in areas such as medical research should be addressed by using ample safeguards for patient privacy. These records often tend to be big data, and given that a significant portion is stored as free (unstructured) text, we decided to examine relevant work on automated free text de-identification with recurrent neural network (RNN) and conditional random field (CRF) approaches. Both methods involve machine learning and are widely used for the removal of protected health information (PHI) from free text. The outcome of our survey work produced several informative findings. Firstly, RNN models, particularly long short-term memory (LSTM) algorithms, generally outperformed CRF models and also other systems, namely rule-based algorithms. Secondly, hybrid or ensemble systems containing joint LSTM-CRF models showed no advantage over individual LSTM and CRF models. Thirdly, overfitting may be an issue when customized de-identification datasets are used during model training. Finally, statistical validation of performance scores and diversity during experimentation were largely ignored. In our comprehensive survey, we also identify major research gaps that should be considered for future work.

Authors: Rabuffi Paolo , Bruni Antonio , Antonuccio Enzo Gabriele Maria , Ambrogi Cesare , Vagnarelli Simone 
Published: September 2020

Abstract
Background
Flow-diverter stents (FDS) are designed to maintain laminar flow in the parent artery and sidebranches and to promote thrombosis of the aneurysm. Although these devices were developed for use in intracranial circulation, FDS could be employed to treat aneurysms regardless of their location, when anatomic factors may limit the efficacy of classic endovascular techniques. The objective of this study is to describe the initial experience of a single center in the treatment of visceral artery aneurysms and pseudoaneurysms (VAA-VAP) with cerebral FDS, analyzing safety, efficacy and 1-year outcome. Between 2016 and 2018 six patients (4 women, mean age 57.6) underwent treatment with FDS of 4 VAA and 2 VAP located in renal (4), hepatic (1) and splenic arteries (1). Mean aneurysm diameter was 14.3 mm (range 8–22). All the aneurysms had sidebranches arising from the neck or had an unfavorable dome-to-neck ratio. Technical success, safety, efficacy and 1-year outcome were analyzed. Follow-ups (FU) with Color-Doppler US and CTA ranged from 12 to 36 (mean 20) months.

Results
Technical success was achieved in all cases. There were no aneurysm rupture nor reperfusion after exclusion. Five out of six (83.3%) FDS were patent at each FU; all the aneurysms showed shrinkage with a mean dimensional reduction rate of 55.8%. Sac thrombosis was observed in 4 aneurysms at 1 (n = 3) and at 12-month FUs. There was one sidebranch occlusion with evidence of a small area of kidney hypoperfusion at the 12-month FU, which was asymptomatic. In one patient, a reintervention was needed because CTA showed a severe in-stent stenosis, which was symptomatic. Mean hospitalization was 4.1 days.

Conclusions
Treatment of morphologically complex VAA and VAP with cerebral FDS proved to be safe and efficient. Stronger evidence from larger populations are required.

Abstract
Background
Superior Hypogastric nerve Block (SHNB) has been shown to be an effective pain management technique after Uterine Fibroid Embolization (UFE), reducing the need for opiates and allowing same-day discharge after UFE. In this technical note we discuss relevant anatomy and technical details in performing SHNB.

Main body
The Superior hypogastric plexus (SHP) is the part of the abdominopelvic sympathetic nervous system that provides a targeted intervention to sympathetic-mediated pain pathways of pelvic organs and a target for an anterior approach Superior Hypogastric nerve Block after embolization. Vascular structures are in close relation to the intended site of target of the SHP at the L5 vertebral body include aortic bifurcation and IVC confluence, hence a detailed knowledge of this is essential. A step by step technical approach to SHNB includes patient positioning for the block, image guidance and needle positioning, choice and technique of anesthetic injection. Traversing a large fibroid uterus, inadvertent vascular opacification and Local anesthetic systemic toxicity present challenges to performing the block and are addressed.

Conclusion
Superior Hypogastric nerve Block (SHNB) can be a useful tool in the Interventional armamentarium to make UFE a better experience for patients with fibroids, allowing for better pain control as well as facilitating same day discharge. Performing SHNB appear to be can be performed with technical ease for an interventional radiologist.
White, everything white? Josef Frank’s Villa Beer (1930) in Vienna, and its materiality in the context of the discourse on ‘white cubes’
Authors: Hammer Ivo B. 
Published: September 2020

AbstractIn 2017 a group of conservators-restorers conducted a conservation-science study of the materials used in the construction of Josef Frank’s main work, the Villa Beer (1930) in Vienna-Hietzing, and of the building’s surfaces. The study was an opportunity to find evidence indicating whether the contemporary description of the wall colour as a non-colour white corresponded to physical reality. The notion ‘Weiss, alles Weiss’ (‘white, everything white’), celebrated as ‘an expression of values and of the times’ (Hammann, 1930), will be identified as a cultural construct that stands in contradiction to the actual materiality of the buildings of the period. We must rewrite the colour history of Modern Movement architecture. The ‘White Cubes’ were never white.

PURPOSE Combining the oral AKT inhibitor ipatasertib with paclitaxel as first-line therapy for metastatic triple-negative breast cancer significantly improved progression-free survival (PFS) in the placebo-controlled, randomized, phase II LOTUS trial, with a more pronounced effect in patients with PIK3CA/AKT1/PTEN-altered tumors. We report findings from the extensive translational research program. PATIENTS AND METHODS Pretreatment plasma and tumor samples were evaluated for genetic alterations using FoundationACT and FoundationOne (Foundation Medicine, Cambridge, MA) hybrid capture next-generation sequencing assays, respectively. Prevalences of the most common mutations and PIK3CA/AKT1 mutation status were determined using both assays, and concordance was assessed. In longitudinal analyses, circulating tumor DNA (ctDNA) mutations were quantified in baseline and on-treatment (cycle 3, day 1 [C3D1]) samples. The relationship between outcomes and ctDNA fraction (CTF; highest variant allele frequency) and CTF ratio (C3D1 CTF to baseline CTF) was explored. RESULTS Among 89 patients evaluable for ctDNA sequencing, 81 patients (91%) had 149 detectable mutations. There was high agreement between plasma- and tissue-based sequencing for known or likely short variant mutations but not amplifications. There was 100% concordance between ctDNA and tissue sequencing in patients with activating PIK3CA or AKT1 mutations. High baseline CTF was associated with shorter PFS in both treatment arms. Longitudinal analyses showed more favorable outcomes with lower absolute CTF at C3D1 and, to a lesser extent, greater CTF decreases. CONCLUSION These results suggest that plasma ctDNA sequencing may allow reliable and convenient assessment of prognosis and identification of genetic markers associated with increased benefit from ipatasertib. On-treatment CTF showed a meaningful association with objective response and PFS.

Introduction: Over 40 million deaths annually are due to noncommunicable diseases, 15 million of these are premature deaths and physical inactivity attributes an estimated 9% to this figure. Global responses have included the sustainable development goals and the global action plan on physical activity. Both point to policy action in physical activity (PA) to address change, yet the impact of policy is unknown. The protocol described outlines a systematic literature review that will be undertaken by the Policy Evaluation Network to address this knowledge gap. Protocol: This review of school PA policies is the first of seven planned reviews. The seven best investments for promotion of population PA identified in the Toronto Charter (whole-of-school programmes, transport policy, urban design policy, primary health care policy, public education policy, community programmes and sport programmes) will form the basis of these reviews. Seven individual scientific literature searches across six electronic databases, using key concepts of policy, PA, evaluation and a distinct concept for each area will be conducted. This will be supplemented with a search of the reference list of included articles. Methodological quality will be assessed and overall effectiveness for each included study will be described according to pre-determined categories. Conclusions: The review will provide policy makers with a list of policy statements and corresponding actions which the evidence has determined impact on PA directly or indirectly. By collating the evidence, and demonstrating the depth of the science base which informs these policy recommendations, this review will provide guidance to policymakers to use evidence-based or evidence-informed policies to achieve the 15% relative reduction in physical inactivity as defined by the ‘Global Action Plan on Physical Activity’.

Background: Loneliness in later life is often addressed with befriending interventions, yet evidence for their effectiveness is limited. Meanwhile it is known that loneliness has a deleterious impact on health. The aim of the study is to evaluate whether a befriending service for older adults mitigates the impact of loneliness on health outcomes, and to identify mechanisms through which befriending interventions might impact upon health. Methods: A mixed methods design is used. The quantitative component utilises an AB single-case experimental design, to gather intensive longitudinal data. These data will be analysed using a generalised additive modelling approach. The qualitative component of the study uses semi-structured dyadic interviews, structured and analysed according to the principles of constructivist grounded theory. Findings will then be triangulated according to an existing mixed methods integration protocol. Discussion: This mixed methods design has the potential to inform national and international policy in relation to befriending interventions for older adults. In addition, there is the potential for study results to inform our theoretical understanding of the nature of the relationship between loneliness and health.

TILLAGE SYSTEMS IN THE CROP ROTATION IN THE CENTRAL CAUCASIA
Authors: Kuzychenko Yuriy 
Published: September 2020

The research was carried out in order to analyze the development of various systems of basic tillage (moldboard, non-moldboard, surface) for row crops for the period from 2010 to 2018 in the zone of unstable moisture in Stavropol kray with the development of a soil cultivation system for corn for grain according to the predecessor winter wheat. The soil of the experimental plot is ordinary chernozem, medium loamy, with a humus content of 3.9%, Р2О5 - 36.2 mg/kg; К2О - 162.8 mg/kg. The research was carried out in the link of crop rotation winter wheat - corn for grain. The experimental scheme included eight options for the main processing: moldboard (control), moldless (plow with SibIME tines, “Paraplau” type, chisel, flat cutter), milling, shallow (10 ... 12 cm in combination with Roundup herbicide) and combined (moldboard under winter wheat, chisel-making for grain corn). The area of the plot is 240 m2, the arrangement of the plots is two-tiered, randomized, the replication is four times. During the study period, the area cultivated without moldboard to a depth of 20 ... 22 cm, on average, grew by 4.3 thousand hectares annually. The average soil density in the options with moldboard and combined (plowing by 20 ... 22 cm for winter wheat, non-moldboard loosening by 23 ... 25 cm for corn for grain) processing is almost the same as after sowing (1.10 and 1.11 g/cm3) and before harvesting (1.19 g/cm3). The soil water permeability after the main processing with the chisel plow PCh-4.5 was 291 mm/h, plowing - 241 mm/h, which is 15% less. The average for crops in the crop rotation link in the variant with moldboard and combined tillage were practically the same - 136 and 134.6 mm, respectively. Against the fertilized background, the costs for combined tillage versus moldboard tillage (control) decreased by 2300 rubles per hectare, and the profitability of production of the crop rotation link is 89%.

Interviewing Roomba: A posthuman study of humans and robot vacuum cleaners
Authors: Gross Jennifer 
Published: September 2020

Abstract
Roomba, the autonomous robotic vacuum cleaner sold by iRobot since 2002, is now a taken-for-granted household helper in many homes. In this study that cross-cuts phenomenology, postphenomenology, actor–network theory and media ecology, I utilize four heuristics for interviewing digital objects. I interview Roomba and utilize qualitative research methods to theorize about the complexities of the entanglements and relationships between human beings and their robot vacuum cleaners. Conclusions connect to critical theory and feminism and also question justifications of anthropocentrism in a posthuman world.
A posthuman ecology of simulated human patients: Eidolons, empathy and fidelity in the uncanny embodiment of nursing practice
Authors: Ireland Aileen 
Published: September 2020

Abstract
The reproduction of the human form has been a universal practice amongst human ecologies for millennia. Over the past 200 years, popular culture has considered the imaginary consequences of the danger to humanity and human-ness of replicating the autonomous human form too faithfully. Today, the seductive allure of technologically advanced simulated human bodies and advances in robotics and artificial intelligence has brought us closer to facing this possibility. Alongside the simultaneous aversion and fascination of the possibility that autonomous simulated human forms may become indistinguishable from human beings is the deep-rooted uncanniness of the automaton in its strange familiarity – not only to ourselves but to our pleasant childhood imaginings of playing with dolls. As such, simulated human bodies are often enrolled in medical and nursing education models with the assumption that making the simulation teaching spaces seem as close to clinical spaces as possible will allow students to practise potentially harmful clinical skills without causing any harm to human patients. However similar the simulated human bodies may appear to a living, breathing human, a tension between the embodiment of particularly human attributes and their replication persists. How can computerized human patient simulators be enrolled to teach people to develop the necessary attributes of compassion and empathy when caring for human beings? This article explores the uncanny ecologies of simulated human patients in nursing education by presenting a posthuman analysis of the practices of nurse educators as they enrol these digital objects in their teaching. Guided by a selection of heuristics offered as a mode of interviewing digital objects, the analysis enrolled ‘Gathering Anecdotes’ and ‘Unravelling Translations’ to attune to the ways in which these uncanny posthuman assemblages become powerful modes of knowing to mobilize learning about human attributes within uncanny posthuman ecologies.

Implementing the 2013 curriculum, these madrassas have generally begun to apply scientific learning. However, it still cannot be carried out optimally. This article aims to find out the improvement in the quality of Arabic learning in MI (Madrasah Ibtidaiyah) in Kartasura District which is characterized by an increase in teacher skills in developing activity-based Arabic learning strategies, the variety of learning activities, the activeness of students in participating in learning and increasing the ability of Arabic language learners. By using the Service-Learning approach which is integrated with Participatory Action Research with the main stages of preparation or planning, serving or action, and evaluation or reflection. There were 8 madrasas in Kartasura District being observed. Data were collected by observation, interview and documentation, and validated by a focused group discussion. The results of this research show that; the teachers apply various learning activities that are varied for each maharah although the intensity and variation varies. Among the learning activities of mahārah istimā’-kalām is the reinforcement of memorization of Arabic vocabulary and expressions using drill or istimā’-kalām, singing, and word chain. Mahārah qirā'ah has more activities involving reading out loud classically, whether in large groups, small groups, or individual loud reading activities, chain reading, and reading with media such as LCDs, cards, or objects that are given Arabic names. For maharah kitabah, the most widely used activity is imla', follow the line, stringing words into sentences, and guided writing through assignments. The activeness of the students in participating in learning also increased, although not too significantly. Likewise with the activeness and ability of Arabic language. After implementing the activity-based learning, the students the language ability has also increased.
