Physiology of the Right Ventricle Across the Lifespan
Authors: Woulfe Kathleen C. , Walker Lori A.
Published: March 2021

The most common cause of heart failure in the United States is ischemic left heart disease; accordingly, a vast amount of work has been done to elucidate the molecular mechanisms underlying pathologies of the left ventricle (LV) as a general model of heart failure. Until recently, little attention has been paid to the right ventricle (RV) and it has commonly been thought that the mechanical and biochemical properties of the RV are similar to those of the LV. However, therapies used to treat LV failure often fail to improve ventricular function in RV failure underscoring, the need to better understand the unique physiologic and pathophysiologic properties of the RV. Importantly, hemodynamic stresses (such as pressure overload) often underlie right heart failure further differentiating RV failure as unique from LV failure. There are significant structural, mechanical, and biochemical properties distinctive to the RV that influences its function and it is likely that adaptations of the RV occur uniquely across the lifespan. We have previously reviewed the adult RV compared to the LV but there is little known about differences in the pediatric or aged RV. Accordingly, in this mini-review, we will examine the subtle distinctions between the RV and LV that are maintained physiologically across the lifespan and will highlight significant knowledge gaps in our understanding of pediatric and aging RV. Consideration of how RV function is altered in different disease states in an age-specific manner may enable us to define RV function in health and importantly, in response to pathology.

A Risk Management Database Framework Implementation for Transportation Asset Management
Authors: Nlenanya Inya , Smadi Omar
Published: March 2021

A 2017 survey of the state of practice on how agencies are developing their risk-based asset management plan shows that state highway agencies are increasingly adapting the way they do business to include explicit considerations of risks. At the moment, this consideration of risk is not linked to data. Hence, there is a lack of integration of risk management in driving strategic cross-asset programming and decision-making. This paper proposes and implements a risk management database framework as the missing piece in the full implementation of a risk-based transportation asset management program. This risk management database framework utilizes Geographic Information Systems (GIS) and Application Programming Interface (API) to implement a risk management database of all the relevant variables an agency needs for risk modeling to improve risk monitoring, risk register updates, and decision-making. This approach allows the use of existing enterprise as well as legacy data collection systems, which eliminates the need for any capital-intensive implementation cost. Furthermore, it provides transportation agencies with the ability to track risk in quantitative terms, a framework for prioritizing risk, and the development of an actionable plan for risk mitigation. In this paper, the implementation of the fully integrated GIS-enabled risk management database employs the Iowa department of transportation (DOT) data and risk register.
Path-Independent Consideration
Authors: Lleras Juan , Masatlioglu Yusufcan , Nakajima Daisuke , Ozbay Erkut
Published: March 2021

In the context of choice with limited consideration, where the decision-maker may not pay attention to all available options, the consideration function of a decision maker is path-independent if her choice cannot be manipulated by the presentation of the choice set. This paper characterizes a model of choice with limited consideration with path independence, which is equivalent to a consideration function that satisfies both the attention filter and consideration filter properties from Masatlioglu et al. (2012) and Lleras et al. (2017), respectively. Despite the equivalence of path-independent consideration with the consideration structures from these two papers, we show that, to have a choice with limited consideration that is path-independent, satisfying both axioms on the choice function that characterize choice limited consideration with attention and consideration filters unilaterally (from Masatlioglu et al. (2012) and Lleras et al. (2017)) is necessary but not sufficient.

The reconstruction of computed tomography (CT) images is an active area of research. Following the rise of deep learning methods, many data-driven models have been proposed in recent years. In this work, we present the results of a data challenge that we organized, bringing together algorithm experts from different institutes to jointly work on quantitative evaluation of several data-driven methods on two large, public datasets during a ten day sprint. We focus on two applications of CT, namely, low-dose CT and sparse-angle CT. This enables us to fairly compare different methods using standardized settings. As a general result, we observe that the deep learning-based methods are able to improve the reconstruction quality metrics in both CT applications while the top performing methods show only minor differences in terms of peak signal-to-noise ratio (PSNR) and structural similarity (SSIM). We further discuss a number of other important criteria that should be taken into account when selecting a method, such as the availability of training data, the knowledge of the physical measurement model and the reconstruction speed.
Text File Privacy on the Cloud Based on Diagonal Fragmentation and Encryption
Authors: Barhoom Tawfiq , Abu Shawish Mahmoud
Published: March 2021

Despite the growing reliance on cloud services and software, privacy is somewhat difficult. We store our data on remote servers in cloud environments that are untrusted. If we do not handle the stored data well, data privacy can be violated with no awareness on our part. Although it requires expensive computation, encrypting the data before sending it appears to be a solution to this problem. So far, all known solutions to protect textual files using encryption algorithms fell short of privacy expectations. Thus is because encrypting cannot stand by itself. The encrypted data on the cloud server becomes full file in the hand causing the privacy of this data to be intrusion-prone, thus allowing intruders to access the file data once they can decrypt it.
This study aimed to develop an effective cloud confidentiality model based on combining fragmentation and encryption of text files to compensate for reported deficiency in encryption methods. The fragmentation method used the strategy of dividing text files into two triangles through the axis. Whereas the encryption method used the Blowfish algorithm.
The research concluded that high confidentiality is achieved by building a multi-layer model: encryption, chunk, and fragmentation of every chunk to prevent intruders from reaching the data even if they were able to decrypt the file. Using the privacy accuracy equation (developed for the purpose in this research), the model achieved accuracy levels of 96% and 90% when using 100 and 200 words in each chunk on small, medium, and large files respectively.
Hybrid-Approach-Based Feature Selection for Magnetic Reverberation Imaging Brain Tumor Classification
Authors: Hadi Amjad Mahmood , Al-Abass Gesoon Jawid A.K. , Hussain Firas Faeq K.
Published: March 2021

The World Health Organization reported that the brain tumor is one of the serious diseases because it affects a large number of people including children around the world. Developing a system to detect brain tumors at an early stage would help save the lives of many people. Much research has been made in this area to develop a system for detecting brain tumors, but this system needs to be improved, its accuracy enhanced and the time taken for the classification of brain tumors reduced. Thus, feature selection methods are required to enhance the system. The feature selection method is more significant in the data mining algorithm to remove redundant features from the data set. In this paper, I proposed a hybrid Principal Component Analysis and Rough Set theory (PCA + RST) approach to reduce the dimension of the data set. The approach is evaluated using ADNT and OASIS standard databases. Two segmentation methods were applied to find out the region of interest from the MRI image. To obtain several features from an MRI image, the Discrete Wavelet Transform (DWT) methods are employed. The novelty of the proposed new hybrid PCA+RST approach is to obtain the most significant features for enhancing the classification algorithms. Four classification algorithms namely J48, Support Vector Machine (SVM), K-nearest neighbor (KNN) and Naive Bayes have been implemented. Evaluation and comparison of the proposed approach with alternative approaches like DWT+SVM, DWT+PCA+ANN, DWT+PCA+KNN, STRSPOS-QR+J48, and STRSPOS-QR+Naive Bayes are presented. The proposed approach outperforms both these approaches.
A Proposed Generalized Eigenfaces System for Face Recognition Based on One Training Image
Authors: Salah Shaimaa Khudhair , Humood Waleed Rasheed , Khalaf Ahmed Othman
Published: March 2021

This paper discusses the results of a study that aimed to develop an eigenface technique known as (PC) 2A that collect the image of the original face with its vertical and horizontal projections. The basic components of the image were analyzed in the image enrichment section. An evaluation of the proposed method demonstrates that it costs less than the standard eigenface technique. Moreover, the experimental results show that a front-end database that has a gray level for each person has one training image; thus, in terms of accuracy, it was possible to get a 3-5% result for the proposed (PC)2A, which is higher than the precision of the standard eigenface technique. The main objective of this paper is to demonstrate the weaknesses and strengthens of the facial recognition approach as an identifier known as eigenfaces. This aim was achieved by using the principal components analysis algorithm based on the images of previously stored training data. The outcomes show the strength of the proposed technique, in which it was possible to obtain accuracy results of up to 96%, which in turn provides support for developing the technique proposed in this paper in the future because this work is of great importance in the field of biological treatments, the need for which has significantly increased over the last 5 years.

AbstractThis paper aims to discuss how the characteristics of the saluang show succeeded in being influenced by the postmodern that entered the lives of the people in Minangkabau. Bahoyak is a revealing medium used in the development of saluang jokes that have been somewhat influenced by postmodern culture. This is a new way of development in saluang kicking performances when society is easy to accept and there is no sense of burden when faced with postmodern culture. The people of Minangkabau especially fellow rang pagurau have the same hobby in enjoying the show saluang dendang, even though it is influenced by the development of the cultures that exist in Minangkabau society especially in the audience saluang dendang. The musical concept in saluang kicking on Bahoyak is prioritized with the sharpness of the kicker in making a sarcophagus and the development of the instrument in this show that makes the pagurau dragons dissolve in the show saluang dendang even though the show is already far away and experiencing a shift from the show tradisinya.Keywords : Bahoyak, Minangkabau, postmodern, characteristic, saluang dendangAbstrakTulisan ini bertujuan untuk membahas tentang bagaimana ciri khas dalam pertunjukan saluang dipengaruhi oleh postmodern yang masuk dalam kehidupanmasyarakat di Minangkabau. Bahoyak merupakan sebuah media ungkap yang digunakan dalam pengembangan saluang dendang yang telah dipengaruhi oleh budaya postmodern. Hal ini merupakan sebuah cara pengembangan baru dalam pertunjukan saluang dendang ketika masyarakat dengan mudahnya menerima dan tidak ada rasa beban ketika dihadapkan dengan budaya postmodern. Masyarakat MinangkabauÂ  khususnya sesama rang pagurauÂ  mempunyai hobi yang sama dalam menikmati pertunjukan saluang dendang, sekalipun itu dipengaruhi oleh perkembangan budaya-budaya yang terdapat dalam lingkungan masyarakat Minangkabau. Konsep musikal dalam saluang dendang pada Bahoyak diutamakan pada kejelian pendendang dalam membuatkan sebuah pantun sindiran dan perkembangan instrument di dalam pertunjukan ini, sehingga membuat rang pagurau larut di dalam pertunjukan saluang dendang, meskipun pertunjukan tersebut sudah mengalami penggeseran dari pertunjukan tradisinya.Kata kunci : Bahoyak, Minangkabau, postmodern, ciri khas, saluang dendang

ABSTRACTLearning resources are basically available in the surrounding environment. A learning approach based on the surrounding environment will provide a more interesting learning experience and can stimulate positive motivation. In order for the learning process to be carried out well, enrichment of the learning resources needs to be done. This study aims to get an overview of learning methods based on the surrounding environment by utilizing decorative ornaments at the Palembang Great Mosque as a learning resource. Furthermore, through this research researchers are expected to get a formulation of the use of decorative ornaments at the Palembang Great Mosque as a source of learning. Aside from being a form of support for the government in the context of inheritance and maintaining physical cultural products in the form of written documentation. It is very rare to find art textbooks, especially about decoration. In fact, the author has not yet found a textbook specifically discussing the various decorations in Palembang, so this research needs to be done. The author is of the opinion that, the use of ornamental diversity at the Palembang Grand Mosque as a source of learning art knowledge can be done through two methods namely, observing forms of ornamentation directly in the field or through enriching learning resources.Keywords : Learning Resources, Decorative Ornament, visual arts learningABSTRAKSumber belajar pada dasarnya sudah tersedia di lingkungan sekitar.

Land is one of the potential natural resources to be developed optimally to increase local revenue. Based on the availability of water, land is grouped into two major groups, which are wetland and dry land (upland). The use of dry land for agriculture is often ignored by policy makers. Problems in dry land management vary in each region, both technical and socio-economic aspects. However, with the right strategy and technology, these problems can be overcome. Efforts to manage dry land to increase food production face problems, including steep slopes, low soil fertility, and water shortages. These problems need to be overcome by applying the right technology. Dry land management technology is available, including management of soil fertility, soil conservation, land rehabilitation, and efficient management of water resources. The problem is the weak dissemination of innovative technology to farmers and the slow adoption of this technology. Utilization of dry land to increase food production requires appropriate planning and strategies.

В статье приведены результаты оценки биологической и экономической эффективности опытного образца микробиологического препарата Бацикол, биохимического – Фитоверм, химического – Актара, 3-х средств, получаемых на основе растения Табамин, табачного мыла и экстракта из хвои в борьбе с крестоцветной блошкой и капустной мухой на капусте. Эффективность препаратов была достаточной для снижения численности вредителей ниже экономического порога вредоносности. При этом наибольшую эффективность показал химический препарат Актара, обработки которым делали, пропуская 1 гребень (рядок). Окупаемость препаратов была наибольшей в варианте, где применяли Актара.
When Government Transparency Risks Reinforcing Racist Stereotypes and Residential Segregation
Authors: Craemer Thomas
Published: March 2021

Transparency requires that online government information be both numerically accurate and ‘cognitively accessible’ to members of the public. This paper provides a normative critique of various crime-data presentation formats informed by the literature on cognitive biases with regard to quantitative information. The analysis finds that interactive crime maps often apply (1) relative scaling, (2) arbitrary rate-magnification, (3) context-free absolute numbers, (4) ratios of small proportions, and (5) wrong baselines of comparison. These formats risk portraying non-White and/or Hispanic urban areas as ‘high crime’ in absolute rather than relative terms. This may discourage cautious (White) individuals from visiting, doing business in, or relocating to such neighborhoods, thus reinforcing residential segregation. Proportional scaling may provide an easy solution: In 2017, New York City emerges as a safe zone with regard to violent crime. Proportional scaling is easy to implement and it may help prevent inadvertent reinforcement of racist stereotypes and residential segregation.

Amaç: Sevk alan üçüncü basamak merkezimizde yapılan elektif ve acil servikal serklaj sonuçlarını incelemeyi ve etkinliklerini değerlendirmeyi amaçladık

Gereçler ve Yöntem: Bursa Yüksek İhtisas Eğitim ve Araştırma Hastanesi’nde Ocak 2016 ile Ocak 2020 arasında servikal yetmezlik tanısıyla servikal serklaj yapılan toplam 56 hastanın sonuçları retrospektif olarak incelenmiştir. Transvajinal olarak Mc-Donald tipi serklaj uygulanan hastalar çalışmaya dahil edilmiştir. Çoğul gebeliği olan, abdominal serklaj uygulanan ve doğum sonuçlarına ulaşılamayan hastalar çalışma dışı bırakılmıştır. Serklaj yapılma endikasyonuna göre hastalar; elektif serklaj (öykü endikasyonlu) ve acil serklaj (fizik muayene ve ultrasonografi endikasyonlu) olmak üzere iki grupta incelenmiştir.

Bulgular: Serklaj işleminin yapıldığı gebelik haftası elektif ve acil grupları için sırasıyla 20.8±0.7 ve 13.9±0.1 hafta olarak saptandı. Elektif serklaj yapılan grupta serklaj işlemi ile doğum arasında geçen süre ile doğumun gerçekleştiği hafta belirgin olarak daha fazlaydı (151.1±6.5 gün / 35.2±0.9 hafta vs 23.7±18.5 gün / 26.6±1.4 hafta ). Bununla ilişkili olarak da doğum ağırlığı elektif serklaj yapılan grupta acil serklaj yapılan gruptan anlamlı olarak daha fazlaydı ( 2913.7±129 gr vs 1611.4±232.2 gr). Yenidoğan yoğun bakım gereksinimi ise elektif serklaj grubunda daha azdı. Doğum şekli ve abortus oranı açısından ise her iki grup arasında istatiksel anlamlı fark yoktu.

Sonuç: Ağrısız servikal açıklık ile başvuran ya da ultrasonografide belirgin kısa servikse sahip hastalarda yapılan acil serklaj da elektif serklaj kadar olmamakla birlikte gebelik süresini uzatmada ve kötü perinatal sonuçları azaltmada etkilidir. Elektif serklaja kıyasla acil serklaj etkinliğini belirlemek için acil serklaj uygulanan hastaların daha iyi randomize edildiği daha fazla hasta sayısı ile yapılacak prospektif çalışmalara ihtiyaç vardır.
Host Galaxy Mass Combined with Local Stellar Age Improve Type Ia Supernovae Distances

Published: March 2021

Type Ia supernovae (SNe Ia) are standardizable candles, but for over a decade there has been a debate on how to properly account for their correlations with host galaxy properties. Using the Bayesian hierarchical model UNITY, we simultaneously fit for the SN Ia light curve and host galaxy standardization parameters on a set of 103 Sloan Digital Sky Survey II SNe Ia. We investigate the influences of host stellar mass, along with both localized (r <3 kpc) and host-integrated average stellar ages, derived from stellar population synthesis modeling. We find that the standardization for the light-curve shape (α) is correlated with host galaxy standardization terms (γ

i
) requiring simultaneous fitting. In addition, we find that these correlations themselves are dependent on host galaxy stellar mass that includes a shift in the color term (β) of 0.8 mag, only significant at 1.2σ due to the small sample. We find a linear host mass standardization term at the 3.7σ level, that by itself does not significantly improve the precision of an individual SN Ia distance. However, a standardization that uses both stellar mass and average local stellar age is found to be significant at >3σ in the two-dimensional posterior space. In addition, the unexplained scatter of SNe Ia absolute magnitude post standardization, is reduced from

to 0.109 ± 0.017 mag, or ∼10%. We do not see similar improvements when using global ages. This combination is consistent with either metallicity or line-of-sight dust affecting the observed luminosity of SNe Ia.
It’s Dust: Solving the Mysteries of the Intrinsic Scatter and Host-galaxy Dependence of Standardized Type Ia Supernova Brightnesses
Authors: Brout Dillon , Scolnic Daniel
Published: March 2021

The use of Type Ia supernovae (SNe Ia) as cosmological tools has motivated significant effort to understand what drives the intrinsic scatter of SN Ia distance modulus residuals after standardization, characterize the distribution of SN Ia colors, and explain why properties of the host galaxies of the SNe correlate with SN Ia distance modulus residuals. We use a compiled sample of ∼1450 spectroscopically confirmed photometric light curves of SNe Ia and propose a solution to these three problems simultaneously that also explains an empirical 11σ detection of the dependence of Hubble residual scatter on SN Ia color. We introduce a physical model of color where intrinsic SN Ia colors with a relatively weak correlation with luminosity are combined with extrinsic dust-like colors (E(B − V)) with a wide range of extinction parameter values (R

V
). This model captures the observed trends of Hubble residual scatter and indicates that the dominant component of SN Ia intrinsic scatter is variation in R

V
. We also find that the recovered E(B − V) and R

V
distributions differ based on global host-galaxy stellar mass, and this explains the observed correlation (γ) between mass and Hubble residuals seen in past analyses, as well as an observed 4.5σ dependence of γ on SN Ia color. This finding removes any need to ascribe different intrinsic luminosities to different progenitor systems. Finally, we measure biases in the equation of state of dark energy (w) up to ∣Δw∣ = 0.04 by replacing previous models of SN color with our dust-based model; this bias is larger than any systematic uncertainty in previous SN Ia cosmological analyses.

A new species of the Asian leaf litter toad genusLeptobrachellais described from Guizhou Province, China. Molecular phylogenetic analyses support the new species as an independent lineage deeply nested in theLeptobrachellaclade. The new species is distinguished from its congeners by a combination of the following morphological characters: body size medium (SVL 29.7–31.2 mm in five adult males); dorsal skin shagreened, some of the granules forming longitudinal short skin ridges; tympanum distinctly discernible, slightly concave; supra-axillary, femoral, pectoral and ventrolateral glands distinctly visible; absence of webbing and lateral fringes on fingers; toes with narrow lateral fringes but without webbing; heels overlapping when thighs are positioned at right angles to the body; tibia-tarsal articulation reaching the middle of eye when leg stretched forward. The discovery highlighted the underestimated species diversity in theLeptobrachellatoads in southwestern China.
La construction d’une stratégie d’influence épistémique dans les négociations internationales : le cas de l’International Military Council on Climate and Security
Authors: Estève Adrien
Published: March 2021

Dans ses rapports publiés en 2019, le Groupe d’experts intergouvernemental sur l’évolution du climat (GIEC) estime que le changement climatique pourrait accélérer ou intensifier certains risques sécuritaires dans le monde. Ce lien entre climat et sécurité est également mis en avant par plusieurs centres de recherche étatsuniens et européens, en particulier dans des travaux financés par le secteur de la défense depuis le début des années 2010. Ces équipes d’experts ont en effet publié un nombre croissant de rapports qui étudient l’impact du changement climatique sur les missions des forces armées. Or, depuis peu, ils ne se contentent plus de répondre à des appels d’offre publiés par les organisations de défense, mais se rassemblent dans de nouveaux réseaux internationaux. Dans cet article, nous montrons que ces réseaux d’experts participent aux négociations internationales au sein de plusieurs forums consacrés à la sécurité et au climat, afin d’imposer une lecture sécuritaire et militaire du changement climatique. Nous étudions en particulier le cas de l’International Military Council on Climate and Security (IMCCS), et son implication dans deux forums de négociations internationales (la Planetary Security Initiative et la Conférence de Munich sur la Sécurité). Cette contribution s’appuie sur une série d’entretiens réalisés à Paris, Washington et La Haye auprès d’experts étatsuniens et français, ainsi que sur une analyse d’archives institutionnelles.
