Ascending Aortic Aneurysm Repair Combined with Ozaki Procedure: Our First Experience
Authors: Gabriyelyan A. , Beleyovych V. , Domansky T. , Beregovoy O. , Romanova S. , Kudlay I. , Chaikovska S.
Published: June 2020

Introduction. Aortic valve disease is often combined with the ascending aortic aneurysm. According to a number of authors, the frequency of the diagnosis varies from 9 to 50%, and the condition requires one-stage surgical correction. Typically, in these cases, mechanical or biologic prostheses are used. The Ozaki procedure allows such operations to be performed without replacing the aortic valve with an artificial prosthesis.
The aim. To analyze the results of aortic valve reconstruction using the Ozaki technique combined with ascending aortic aneurysm repair.
Materials and methods. The article describes the first experience of treatment of 12 patients with aortic valve disease and ascending aortic aneurysm. All the patients underwent Ozaki procedure modified by J. Benedik with surgical correction of aneurysm of the ascending aorta and the aortic arch.
Results and discussion. No deaths were observed in the postoperative period. There was no conversion to aortic valve replacement. Ultrasound imaging after 3 and 6 months revealed no aortic valve dysfunction. Clinically, patients’ well-being was satisfactory and they returned to normal life. Long-term results of these operations interventions require further study.
Conclusions. Our first clinical experience showed promising short- and medium-term results. The indications for aortic valve reconstruction are the same as those for valve replacement with a bioprosthesis. Ozaki procedure can be successfully combined with ascending aortic aneurysm repair. The main advantage is the absence of a frame that does not narrow the opening area of the valve and preserves the aortic root function, which is very important for patients with a narrow aortic root.
Ischemic Preconditioning for Off-Pump Isolated Coronary Artery Bypass Grafting
Authors: Ioffe N. , Salo S. , Rudenko M.
Published: June 2020

National Amosov Institute of Cardiovascular Surgery is a pioneer in implementation of coronary artery bypass grafting (CABG) in our country [1]. Since 2000, over 13,000 off-pump CABG operations were performed in our clinic [2]. At the same time, reperfusion syndrome, which develops during the formation of distal anastomoses and in the postoperative period, can induce intraoperative heart failure and life-threatening arrhythmias [3], despite the fact that off-pump CABG has a number of advantages versus on-pump. Damage to the myocardium, accompanied by an increase in the level of troponin after surgery, leads to deterioration in the patients [4]. That is why the use of pre- and postcodification techniques during off-pump CABG is an important component of successful surgical intervention. The literature describes many methods of ischemic and pharmacological pre- and postconditioning, but their mechanisms have not yet been fully understood [5]. Ischemic preconditioning (PreC) is an increase in myocardial resistance to ischemia-reperfusion that results from the pre-exposure to short-term ischemia and is expressed through intracellular mechanisms. Our study included 52 cases of off-pump coronary artery bypass grafting (OPCABG). The subjects were divided into 2 groups. The patients of group 1 underwent ischemic PreC before surgical intervention. In group 2, no preoperative PreC was performed. Hemodynamic parameters were analyzed in all the subjects during the surgical intervention.

Published: June 2020

Mortality in acute dissecting type A aortic aneurysm remains high. The existing classifications are intended to give an accurate, and, very importantly (given the acute course of the pathology), a prompt answer to the clinician’s and the cardiac surgeon’s questions: how the patients should be treated, and which of them should undergo surgical intervention, and which procedure is to be used.

Aim. A review and analysis of the existing classifications of dissecting aortic aneurysms and their transformation taking into account the advances in diagnostic technologies and methods of surgical management. The first classification was proposed by DeBakey; it systematized morphological variants of the disease and explained the origin of its accompanying phenomena such as heart tamponade, acute aortic valve insufficiency, and visceral and limb ischemia, but provided no guidelines on treatment techniques. A more recent Stanford classification was based on the principle of differentiation into conservative or operative approach. Owing to the use of CT and MRI angiography, new dissection subtypes were discovered and formulated in the Svensson classification. The Penn classification recommends that the choice of management can be based on the extent of aortic dissection, the site of the primary intimal tear, and the presence of malperfusion. The latest TEM classification identifies type A and type B dissection, as well as additional non-A-non-B type, in which the descending aorta and the arch, but not the ascending aorta, are involved. The most appropriate surgical procedures for the retrograde type A aortic dissection treatment are discussed as well.

Conclusions. 1. The purpose of clinical classification of acute aortic dissection is, in addition to systematizing concepts and categories, facilitating the selection of an optimal state-of-the-art treatment method. 2. Introducing such classifications as Penn or TEM will bring to a common denominator the results of surgical management of acute type A dissection by unifying the characteristics of the patients and eliminating their deliberate or accidental pre-selection, which possibly accounts for the difference in mortality rates among different surgical groups.

E-learning is an educational media that use ICT in the learning process. Nowadays, most of the higher education (universities) in Indonesia have integrated the learning process with e-learning systems. By using this system, learning can be done outside the classroom, anytime and anywhere. Based on the literature reviews, e-learning has many positive impacts on higher education components and its ecosystems, i.e., students, lecturers, higher education staff, and campus officials. Although it offers many advantages, similar to the information technology in general, e-learning systems are also vulnerable to security issues. Because, several security holes in the system can be penetrated easily by hackers, where the essential data contained in e-learning has high potential to be spoofed even modified by irresponsible parties. The security aspect of the e-learning system must be considered to minimize risks. Thus, the higher education can run their business as well. This paper aims to elaborate on the e-Learning system, opportunities, challenges, and several offered solutions on it.

Textbooks and storybooks are the ones used as a source of knowledge. When children read a book, they will try to interpret each word and sentence in it. However, it will be a problem if the book contains vulgar words and indecent sentences. For children at the elementary school level, it is not allowed. For this research, we called that content as gereflekter content. Based on these problems, this research was conducted by building a system to detect gereflekter content in the text of the child's stories that were used as a data set. A system is built by using Naïve Bayes Classifier (NBC) and then evaluated in two scenarios using accuracy, precision, and recall metrics because the characteristics of the data set are imbalanced with the amount of data in the negative class are greater than the data in the positive class. From evaluation results, test scenario produced a high average precision of 99.01%, whereas the recall value has an average of above 50%. From these two values, it can be concluded that the model built by the system has not detected the class properly, but highly trusted when it does.

Published: June 2020

Cyber deterrence by denial strategy can be practised by the state by making it hard for adversaries to succeed any attempt of attacking. It was practised during nuclear deterrence strategies as well as in many other conventional deterrence. This paper argues the functionality of cyber deterrence by denial in deterring cyber threats. In this paper, our attempt is to define cyber deterrence by denial, model it, explore operational roles of cyber security technologies in approaching deterrence by denial within cyber space. Model analysis shed lights over practicing deterrence by denial and its vital role in understanding how efficiently denial can work in maximize failure of any attack which will impact in maximizing cost of cyber attacks to the attacker. Due to limitations in cyber security technologies, unknown cyber threat might not be deterred with assumed approach. Proposed model confirmed that deterrence by denial strategy might works in deterring known cyber threats within instrumental model. As for the benefit of enhancing deterrence in cyber space there is a serious need to reduce the tendency to ignore exploring this strategy.

All in this together: deservingness of government aid during the COVID-19 pandemic
Authors: Bridgman Aengus , Merkley Eric
Published: June 2020

The COVID-19 pandemic has placed unprecedented pressure on governments to engage in widespread cash transfers directly to citizens to help mitigate economic losses. These programs are major redistribution efforts aimed at a variety of sub-groups within society (the unemployed, those with children, those with pre-existing health conditions, etc.) and there has been remarkably little resistance to these government outlays. We employ a novel and pre-registered paired vignette experiment to assess support for government aid during the pandemic in a large, nationally representative sample. We evaluate whether the “normal” deservingness hierarchy and considerations of social affinity or material self-interest continue to drive preferences of Canadians regarding redistribution. We find only small deservingness considerations and little evidence that redistribution preferences are informed by similarity considerations. Instead, we find broad, generous, and non-discriminatory support for direct cash transfers during this period of crisis.

Published: June 2020

Human-computer hybrid teams can meet challenges in designing complex engineered systems. However, the understanding of interaction in the hybrid teams is lacking. We review the literature and identify four key attributes to construct design research platforms that support multi-phase design, hybrid teams, multiple design scenarios, and data logging. Then, we introduce a platform for unmanned aerial vehicle (UAV) design embodying these attributes. With the platform, experiments can be conducted to study how designers and intelligent computational agents interact, support, and impact each other.
Comparing memory capacity across stimuli requires maximally dissimilar foils: Using deep convolutional neural networks to understand visual working memory capacity for real-world objects
Authors: Brady Timothy F. , Störmer Viola S.
Published: June 2020

The capacity of visual working and visual long-term memory play a critical role in theories of cognitive architecture and the relationship between memory and other cognitive systems. Here, we argue that before asking the question of how capacity varies across different stimuli or what the upper bound of capacity is for a given memory system, it is necessary to establish a methodology that allows a fair comparison between distinct stimulus sets and conditions. One of the most important factors determining performance in a memory task is target/foil dissimilarity. We argue that only by maximizing the dissimilarity of the target and foil in each stimulus set can we provide a fair basis for memory comparisons between stimuli. In the current work we introduce a new way to pick such foils objectively for complex, meaningful real-world objects by using deep convolutional neural networks, and we validate this using both memory tests and similarity metrics. Using this method, we then provide evidence that there is a greater capacity for real-world objects relative to simple colors in visual working memory; critically, we also show that this difference can be reduced or eliminated when non-comparable foils are used, potentially explaining why previous work has not always found such a difference. Our study thus demonstrates that working memory capacity is not fixed capacity but depends critically on the type of information that is remembered, and offers a solution of how to compare memory performance and other cognitive systems across different stimulus sets on common ground.
The cortisol awakening response predicts a same-day index of executive function in healthy young adults
Authors: Law Robin
Published: June 2020

The cortisol awakening response (CAR) is associated with various aspects of cognition, including executive function, in older adult and clinical samples. However, the association between these variables in the healthy functioning population is not well understood due to the limited number of appropriately controlled studies. This study explored the association between the CAR and a set shifting index of executive function in 55 (44 females) healthy participants aged 20.2±3.0 years. Notoriously, assessment of the CAR from self-collected saliva samples within the domestic setting is subject to sample timing error, so electronic monitoring of both awakening and sampling times were employed. Participants attended the laboratory in the afternoon of CAR assessment for testing on the Attention Switching Task of the CANTAB neuropsychological testing battery. A positive association was found between CAR magnitude and attention-switching performance in the afternoon of the same day. This was independent of known relevant CAR covariates, but only evident in CAR data collected without delay exceeding 8 min post-awakening. These findings offer insight into a potential role for the CAR in modulating cognitive functions associated with the pre-frontal cortex.
Estimating heritability of psychological traits using the classical twin design; a gentle introduction to concepts and assumptions
Authors: Eftedal Nikolai Haahjem
Published: June 2020

Heritability is a concept that is often misunderstood. The term is used somewhat differently by researchers from how it is used in common parlance. This paper is a gentle introduction to the scientific concept of heritability, and to how it can be estimated for psychological traits in humans through analyses of data from monozygotic and dizygotic pairs of twins. The paper then explores some of the assumptions of the classical twin design, and presents calculations of the consequences of breaking these assumptions. Lastly, the paper introduces multivariate twin modeling, with a focus on how heritability of traits can be impacted by causal effects from other traits, and how twin designs can be informative when making causal inferences.
The role of meaning in visual working memory: Real-world objects, but not simple features, benefit from deeper processing
Authors: Brady Timothy F. , Störmer Viola S.
Published: June 2020

Visual working memory is a capacity-limited cognitive system used to actively store and manipulate visual information. Visual working memory capacity is not fixed, but varies by stimulus type: stimuli that are more meaningful are better remembered. In the current work, we investigate what conditions lead to the strongest benefits for meaningful stimuli. We propose that in some situations, participants may be prone to try to encode the entire display holistically (i.e., in a quick ‘snapshot’), encouraging participants to treat objects simply as meaningless colored ‘blobs’, rather than processing them individually and in a high-level way, which could reduce benefits for meaningful stimuli. In a series of experiments we directly test whether real-world objects, colors, perceptually-matched less-meaningful objects, and fully scrambled objects benefit from deeper processing. We systematically vary the presentation format of stimuli at encoding to be either simultaneous — encouraging a parallel, ‘take-a-quick-snapshot’ strategy — or present the stimuli sequentially, promoting a serial, each-item-at-once strategy. We find large advantages for meaningful objects in all conditions, but find that real-world objects — and to a lesser degree lightly scrambled, still meaningful versions of the objects — benefit from the sequential encoding and thus deeper, focused-on-individual-items processing, while colors do not. Our results suggest single feature objects may be an outlier in their affordance of parallel, quick processing, and that in more realistic memory situations, visual working memory likely relies upon representations resulting from in-depth processing of objects (e.g., in higher-level visual areas) rather than solely being represented in terms of their low-level features.
Gender inequity in speaking opportunities at the American 3 Geophysical Union Fall Meeting

Published: June 2020

Biases—structural, implicit, and explicit—exclude many people from STEM education and employment and devalue their contributions1,2. Most studies focus on bias against women. Few datasets offer enough generalizability or statistical power to evaluate the representation of ethnic and racial minorities, or to examine intersectionality—the compound obstacles that block, for example, a woman of colour in the US. We offer just such a dataset here.
An investigation of novel carrying experience on infant rhythm perception
Authors: Rocha Sinead , Southgate Victoria , Mareschal Denis
Published: June 2020

Prior research suggests infants who are regularly carried in an infant sling are more accurate at moving in time with an auditory rhythm. Moreover, the rate of walking cadence during infant carrying was found to impact infant spontaneous motor tempo. In the current study we ask if part of the advantage of locomotive experience on sensorimotor synchronization results from greater sensorimotor neural activation, utilized to predict the beat, during the perception of rhythmic auditory stimuli. Five-month-old infants were carried at either a Fast or Slow rate. EEG was then used to measure infants’ recruitment of a sensorimotor program, indexed by sensorimotor alpha suppression, during the auditory presentation of the Fast and Slow rhythms. Our results suggest that infants do not seem to preferentially exploit a sensorimotor representation when hearing an auditory tempo that matched the rate at which they were carried, compared to when hearing an incongruent tempo.
Right-Wing Stewards: The Promoting Effect of Religiosity on Environmental Concern Among Political Conservatives in A Global Context
Authors: Hekmatpour Peyman
Published: June 2020

This article studies the relationship between individuals’ religiosity, political ideology, and environmental concern, in a cross-national setting. Drawing data from multiple waves of the World Values Survey (1999-2009), the final sample of this study includes 44,391 respondents nested in 43 countries. By using a multi-level modeling technique, I find that, in general, religiosity is positively associated with respondents’ environmental concerns in terms of willingness to pay for the environment, agreement with increased taxes to prevent environmental pollutions, and choosing environmental protection over economic interests. Political ideology, measured via individuals’ self-placement on a left-right continuum, does not have a meaningful relationship with environmental concern in a global setting. Nevertheless, I observe an interaction effect between religiosity and political ideology. Increased religiosity, particularly among more conservative individuals, is associated with a higher probability of environmental concern. Comparatively, religiosity virtually does not affect liberals’ concern for the natural environment. In other words, the gap between liberals and conservatives regarding the natural environment is more pronounced at lower levels of religiosity; as religiosity increases, the gap starts to narrow. Results suggest that religion has the potential to elevate some of the political barriers on the way towards reaching a collective environmental consciousness.
Interactional Resistance During Black Lives Matter Protests: The Political Stakes of Rebelling Against the Public Order
Authors: Haimson Chloe
Published: June 2020

Note: This is an unedited pre-print of a forthcoming article in Mobilization. This version has not been copy-edited. Drawing from ethnographic research, this study examines how interactions between protesters and police unfold at Black Lives Matter demonstrations in two cities with distinct policing regimes. I argue that protesters consciously resist the terms of engagement set by police in an effort to demonstrate their opposition to police violence and racism, as well as demonstrate that communities can police themselves, while also seeking to avoid arrest or police violence. I call this protesters’ interactional resistance. This resistance is predicated on protesters pushing the boundaries of rules of engagement while using their structural knowledge of the situation and likely police responses. In contrast with prior research, a focus on interactional resistance emphasizes the actions and decisions of protesters, not just the police. It also shows how protesters manage to enact resistance even when they are trying to avoid arrest. Overall, these micro-interactions both point to and shape the structures of repression.
