Published: February 2020

The digital image can be one of the media for information security. The contents of information have an important value of effectiveness, one of which is as a support in decision making. Then the information needs to be done to safeguard the authority of parties who are not responsible. Such security can utilize Steganography and Cryptography (Stego-Crypto). The method used combines Stego-Crypto by randomizing information using Cipher Block Chaining (CBC) then the encryption results are secured through digital images. Based on the test results by measuring the capacity of information on the image produces test data if CBC can process characters in uppercase, spaces and other characters and the results of plaintext and ciphertext produce a ratio of 1: 2, but the LSB performance only accommodates characters depending on the number of sizes on digital image. Testing by evaluating the difference in pixel histogram, when viewed with an invisible not very visible difference, but the insertion of messages with 100-200 characters causes the addition of the average image size on stego images larger than 1: 4, the value of 1 from the original image. Besides, testing with the help of communication media, stego images or encrypted images is able to use email to send stego images because LSB is sensitive to the process of resizing images
KAJIAN METODE METODE STEGANOGRAFI PADA DOMAIN SPASIAL
Authors: Wibisono Gunawan , Waluyo Tri , Ujianto Erik Iman Heri
Published: February 2020

This paper contains a review of the spatial domain steganographic literature. The purpose of this paper is to provide knowledge about techniques or methods that exist in the spatial domain of steganography. Steganography is the science or technique for hiding secret messages in other messages so that the existence of the secret message cannot be accessed by others who do not have authority. There are several popular spatial domains of steganographic techniques, namely LSB (Least Significant Bit), which is mapping secret message bits in the rightmost bit (LSB) of each color pixel and PVD (Pixel Value Differencing) which in this method offers a larger message storage capacity , with better image quality compared to other methods in the spatial domain. Because privacy issues continue to develop along with various digital communication technologies, and increasingly strong security threats, steganography can play a role in society to maintain the confidentiality of both picture, voice and video messages. For this reason it is important for us to be aware of steganographic technology and its implications.

Dissolved oxygen and temperature best predict deep-sea fish community structure in the Gulf of California with climate change implications
Authors: Gallo ND , Beckwith M , Wei CL , Levin LA , Kuhnz L , Barry JP
Published: February 2020

Natural gradient systems can be used to examine the vulnerability of deep-sea communities to climate change. The Gulf of California presents an ideal system for examining relationships between faunal patterns and environmental conditions of deep-sea communities because deep-sea conditions change from warm and oxygen-rich in the north to cold and severely hypoxic in the south. The Monterey Bay Aquarium Research Institute (MBARI) remotely operated vehicle (ROV) ‘Doc Ricketts’ was used to conduct seafloor video transects at depths of ~200-1400 m in the northern, central, and southern Gulf. The community composition, density, and diversity of demersal fish assemblages were compared to environmental conditions. We tested the hypothesis that climate-relevant variables (temperature, oxygen, and primary production) have more explanatory power than static variables (latitude, depth, and benthic substrate) in explaining variation in fish community structure. Temperature best explained variance in density, while oxygen best explained variance in diversity and community composition. Both density and diversity declined with decreasing oxygen, but diversity declined at a higher oxygen threshold (~7 µmol kg-1). Remarkably, high-density fish communities were observed living under suboxic conditions (<5 µmol kg-1). Using an Earth systems global climate model forced under an RCP8.5 scenario, we found that by 2081-2100, the entire Gulf of California seafloor is expected to experience a mean temperature increase of 1.08 ± 1.07°C and modest deoxygenation. The projected changes in temperature and oxygen are expected to be accompanied by reduced diversity and related changes in deep-sea demersal fish communities.

Maternal hyperandrogenism during pregnancy might have metabolic and endocrine consequences on the offspring as shown for the polycystic ovary syndrome. Despite numerous experiments, the impact of prenatal hyperandrogenic environment on postnatal sex steroid milieu is not yet clear. In this study, we investigated the effect of prenatal testosterone excess on postnatal concentrations of luteinizing hormone, corticosterone and steroid hormones including testosterone, pregnenolone, progesterone, estradiol and 7β-hydroxy-epiandrosterone in the offspring of both sexes. Pregnant rats were injected daily with either testosterone propionate or vehicle from gestational day 14 until parturition. The hormones were evaluated in plasma of the adult offspring. As expected, females had lower testosterone and higher pregnenolone, progesterone and estradiol in comparison to males. In addition, corticosterone was higher in females than in males, and it was further elevated by prenatal testosterone treatment. In males, prenatal testosterone exposure resulted in higher 7β-hydroxy-epiandrosterone in comparison to control group. None of the other analyzed hormones were affected by prenatal testosterone. In conclusion, our results did not show major effects on sex hormone production or luteinizing hormone release in adult rats resulting from testosterone excess during their fetal development. However, maternal hyperandrogenism seems to partially affect steroid biosynthesis in sex-specific manner.

The data derived from rat models and the preliminary results of human studies provide strong indices of involvement of common ZBTB16 variants in a range of cardiovascular and metabolic traits. This cross-sectional study in the Caucasian cohort of 1517 Czech adults aimed to verify the hypothesis that ZBTB16 gene variation directly affects obesity and serum lipid levels. Genotyping of nine polymorphisms of the ZBTB16 gene (rs11214863, rs593731, rs763857, rs2846027, rs681200, rs686989, rs661223, rs675044, rs567057) was performed. A multivariate bidirectional regression with the reduction of dimensionality (O2PLS model) revealed relationships between basal lipid levels and anthropometric parameters and some minor ZBTB16 alleles. In men, the predictors – age and presence of minor ZBTB16 alleles of rs686989, rs661223, rs675044, rs567057 – were associated with significantly higher body mass index, waist to hip ratio, body adiposity index, waist and abdominal circumferences, higher total cholesterol and LDL cholesterol and explained 20 % of variability of these variables. In women, the predictors – age and presence of the rs686989 minor T allele – were also associated with increased anthropometric parameters and total cholesterol and LDL cholesterol but the obtained O2PLS model explained only 7.8 % of the variability of the explained variables. Our study confirmed that the selected gene variants of the transcription factor ZBTB16 influence the obesity-related parameters and lipid levels. This effect was more pronounced in men.

Giant dipole resonance of atomic nuclei. Prediction, discovery, and research
Authors: Ishkhanov B S , Kapitonov I M
Published: February 2020

Three quarters of a century ago, in his paper “Quadrupole and dipole γ-emission from nuclei” [J. Phys. USSR 8 331 (1944); Zh. Eksp. Teor. Fiz. 15 81 (1945)], A B Migdal introduced the concept of quantum collective excitation modes into nuclear physics, thereby predicting the phenomenon of giant dipole resonance (GDR). GDR research has had an enormous influence on the formation of modern concepts relating to the dynamics of nuclei. We briefly discuss Migdal’s paper and trace the history of theoretical and experimental studies of GDR. New forms of GDR and analogues of GDR in nonnuclear microsystems are mentioned.

Dedicated to the 75th anniversary of A B Migdal’s work “Quadrupole and dipole γ-emission from nuclei”

The student who encounters The Prince may not have walked through the streets of Florence, yet teachers of political theory can direct students to the visual aspects of his text. As a literary scholar interested in visual culture and a political theorist respectively, we propose an integration of iconographical and close textual readings. We model this multidisciplinary approach for the concepts of prudence, parsimony, liberality, and fortune by showing how the meaning of politicized concepts becomes intelligible through the study of allegorical images. We offer teachers a terminology for interpreting the text through its images. An embedded link offers access to a store of images relevant to the study of The Prince.
Swirlifying Stats Training: Facilitating the Transition to R
Authors: Butler Christopher
Published: February 2020

What works well in teaching statistics and statistical programming to a novice group of students? I present key insights from more than a decade of teaching statistical methods with constant tinkering. These boil down to having frequent online quizzes with unlimited attempts and providing starter scripts with embedded tasks for each lab. Because some changes took effect during the same semester and cohorts vary considerably, this is not a cut-and-dried template for success. However, assessment data is presented to support the value of online quizzes with unlimited attempts. The paper also includes a discussion of transitioning the class from Stata to R and creating interactive tutorials (using the Swirl library in R) to aid learning.
A Contingency Approach to the Undergraduate Political Science Major
Authors: McClellan Fletcher
Published: February 2020

There is a variety of curricular models for organizing the undergraduate political science major. Among them are the traditional distribution model, which exposes students to various subfields in the discipline, and the sequenced learning framework recommended by the Wahlke Report. Other structures include the student learning outcomes approach and civic engagement education, the latter a recent area of emphasis in the discipline. Embedded in these and other course arrangements are underlying theories of how students learn, what a curriculum is, its purpose, and its pedagogy. This study applies curriculum theory to current and potential models of the political science curriculum, describing the strengths and limitations of each structure as a platform for promoting intended learning. The findings suggest that the future political science major should not be a one-size-fits-all framework, but rather a choice from curricula that best address different learning goals and objectives, kinds of students, and program needs.
Party Competition and Cooperation Shape Affective Polarization: Evidence from Natural and Survey Experiments in Israel
Authors: Bassan-Nygate Lotem , Weiss Chagai M.
Published: February 2020

Does electoral competition increase affective polarization? Can cross-party cooperation depolarize voters? Addressing these questions is challenging since both competition and cooperation are endogenous to political attitudes. Building on social identity theory, and leveraging a natural experiment unfolding over seven Israeli election studies, we demonstrate that enhanced electoral competition, measured by interview date proximity to an election, increases affective partisan polarization. We then consider whether party cooperation can depolarize the electorate. To do so, we leveraged the ambiguity around coalition building in Israel’s 22nd election and implemented a survey experiment where we credibly shaped respondents’ perceptions regarding the likelihood that a unity government will form in the near future. We find that priming party cooperation in the form of a unity government, promotes more tolerance across partisan lines. Our study contributes to the affective polarization literature by causally identifying institutional causes and remedies of polarization in a comparative context.

Introduction: Depression is a major public health concern as it relates to chronic diseases such as cardiovascular diseases, type 2 diabetes mellitus. Despite the association of depression with chronic diseases, a limited number of studies are available to examine the prevalence of depression and its association with socio-economic status (SES)in the US adult general population.

Aim: The purpose of this study was to 1) determine the prevalence of depression among US adult population using current data from National Health and Nutrition Examine Survey (NHANES), 2015- 2016; and 2) examine the magnitude of association of SES with depression among this general adult population.

Methods: We analyzed data from 5,164 participants of NHANES, 2015-2016, which is a multistage cluster sample design survey, representing the non-institutionalized US adult population. Depression was assessed using the Patient Health Questionnaire (PHQ-9). PHQ-9 ≥10 is considered having depression. SES was measured by education and family poverty income ratio (PIR). We categorized PIR into low, medium, and high. Education was categorized into four groups: up to 11th grade, high school completed or general education development (GED), some college or associate of arts, and college graduate or above. Proc survey procedure was applied in SAS 9.2.4 version, and the weighted percentage, and odds ratios (OR) with 95% confidence interval (CI) were reported.

Results: The prevalence of depression was 7.47% in the NHANES, 2015-2016, which represented 16.5 million people. The OR of depression among females was 1.73 times higher (95% CI: 1.30,2.31) compared to males. The OR of depression was 2.98 times higher with low PIR (95% CI: 1.58,5.60) in comparison to people with high PIR.

Conclusion: Given the high prevalence of depression, primary care practitioner, public health professionals, and health care policy makers should be aware of depression with special attention to the female gender and individuals with low PIR.
RNA-Binding Proteins as Targets to Improve Salt Stress Tolerance in Crops

Published: February 2020

Salt stress drastically reduce crop productivity. In order to identify genes that could improve crop salt tolerance, we randomly expressed a cDNA library of the halotolerant sugar beet in a sodium-sensitive yeast strain. We identified six sugar beet genes coding for RNA binding proteins (RBP) able to increase the yeast Na+-tolerance. Two of these genes, named Beta vulgaris Salt Tolerant 3 (BvSATO3) and BvU2AF35b, participate in RNA splicing. The other four BvSATO genes (BvSATO1, BvSATO2, BvSATO4 and BvSATO6) are putatively involved in other processes of RNA metabolism. BvU2AF35b improved the growth of a wild type yeast strain under salt stress, and also in mutant backgrounds with impaired splicing, thus confirming that splicing is a target of salt toxicity. To validate the yeast approach, we characterized BvSATO1 in sugar beet and Arabidopsis. BvSATO1 expression was repressed by salt treatment in sugar beet, suggesting that this gene could be a target of salt toxicity. Expression of BvSATO1 in Arabidopsis increased the plant salt tolerance. Our results suggest that not only RNA splicing, but RNA metabolic processes such as such as RNA stability or nonsense-mediated mRNA decay may also be affected by salt stress and could be biotechnological targets for crop improvement.

Cryosurgery/cryotherapy is a widely used, freezing–thawing technique for the renewal or destruction of pathological tissues by applying localized rapid cooling; however, it still relies on the subjective “expert knowledge” of the physicians without, up to now, real-time monitoring of the treatment. This work focused on assessing the depth of freezing using optical transmission and backscattering measurements from frozen/unfrozen porcine ex-vivo skin samples. An optical fiber-array sensor was subsequently developed to determine the depth of freezing and the associated kill zone during freeze–thawing cycles with sub-millimeter accuracy within the skin tissue.

Published: February 2020

Silicon nanowires are widely used for sensing applications due to their outstanding mechanical, electrical, and optical properties. However, one of the major challenges involves introducing silicon-nanowire arrays to a specific layout location with reproducible and controllable dimensions. Indeed, for integration with microscale structures and circuits, a monolithic wafer-level process based on a top-down silicon-nanowire array fabrication method is essential. For sensors in various electromechanical and photoelectric applications, the need for silicon nanowires (as a functional building block) is increasing, and thus monolithic integration is highly required. In this paper, a novel top-down method for fabricating vertically-stacked silicon-nanowire arrays is presented. This method enables the fabrication of lateral silicon-nanowire arrays in a vertical direction, as well as the fabrication of an increased number of silicon nanowires on a finite dimension. The proposed fabrication method uses a number of processes: photolithography, deep reactive-ion etching, and wet oxidation. In applying the proposed method, a vertically-aligned silicon-nanowire array, in which a single layer consists of three vertical layers with 20 silicon nanowires, is fabricated and analyzed. The diamond-shaped cross-sectional dimension of a single silicon nanowire is approximately 300 nm in width and 20 μm in length. The developed method is expected to result in highly-sensitive, reproducible, and low-cost silicon-nanowire sensors for various biomedical applications.
A Never-Ending Conformational Story of the Quercetin Molecule: Quantum-Mechanical Investigation of the O3′H and O4′H Hydroxyl Groups Rotations

Published: February 2020

The quercetin molecule is known to be an effective pharmaceutical compound of a plant origin. Its chemical structure represents two aromatic A and B rings linked through the C ring containing oxygen and five OH hydroxyl groups attached to the 3, 3′, 4′, 5, and 7 positions. In this study, a novel conformational mobility of the quercetin molecule was explored due to the turnings of the O3′H and O4′H hydroxyl groups, belonging to the B ring, around the exocyclic C-O bonds. It was established that the presence of only three degrees of freedom of the conformational mobility of the O3′H and O4′H hydroxyl groups is connected with their concerted behavior, which is controlled by the non-planar (in the case of the interconverting planar conformers) or locally non-planar (in other cases) TSsO3′H/O4′H transition states, in which O3′H and O4′H hydroxyl groups are oriented by the hydrogen atoms towards each other. We also explored the number of the physico-chemical and electron-topological characteristics of all intramolecular-specific contacts—hydrogen bonds and attractive van der Waals contacts at the conformers and also at the transition states. Long-terms perspectives for the investigations of the structural bases of the biological activity of this legendary molecule have been shortly described.
