Published: January 2022

AbstractTin oxide compounds have been highly studied due to their important properties. Tin Oxide (II) SnO compound is considered an ideal p-type conductive material, with large p-type carrier mobility. It is getting a lot of attention in next-generation electronic applications. In this work, the SnO thin film was deposited on the polyethylene terephthalate (PET) substrate by the thermal evaporation method. The X-ray diffraction pattern revealed the amorphous structure of the SnO/PET thin film. The purity of the SnO/PET film was confirmed using the Raman spectrum. An atomic force microscope was carried out to investigate the topography (roughness and particle size) of the obtained SnO thin film. The optical band gap $$E_{{\text{g}}}^{{{\text{Opt}}}}$$

for SnO/PET thin film in the absorption region was estimated using Tauc’s equation. The refractive index for the SnO/PET thin film was estimated at the normal dispersion range by a single oscillator model. The dielectric optical properties of the SnO/PET thin film were estimated. The calculated third-order nonlinear susceptibility χ(3) and nonlinear refractive index n(2) were in the order of ~ 10−10 and ~ 10−9esu, respectively, within the photon energy range (0.5 to 4 eV). The Sheik–Bahae model was used to determine the nonlinear absorption coefficient βc for SnO/PET thin film. Based on these detailed results, the high nonlinear optical parameters pave the way for the probability of using the SnO/PET in flexible optoelectronics devices.

Published: January 2022

Programs written in C/C++ are vulnerable to memory-safety errors like buffer-overflows and use-after-free. While several mechanisms to detect such errors have been previously proposed, they suffer from a variety of drawbacks, including poor performance, imprecise or probabilistic detection of errors, or requiring invasive changes to the ISA, binary-layout, or source-code that results in compatibility issues. As a result, memory-safety errors continue to be hard to detect and a principal cause of security problems.
In this work, we present a minimally invasive and low-cost hardware-based memory-safety checking framework for detecting out-of-bounds accesses and use-after-free errors. The key idea of our mechanism is to re-purpose some of the “unused bits” in a pointer in 64-bit architectures to store an index into a bounds information table that can be used to catch out-bounds errors and use-after-free errors without any change to the binary layout. Using this memory-safety checking framework, we enable HeapCheck, a design for detecting Out-of-bounds and Use-after-free accesses for heap-objects, that are responsible for the majority of memory-safety errors in the wild. Our evaluations using C/C++ SPEC CPU 2017 workloads on Gem5 show that our solution incurs 1.5% slowdown on average, using an 8 KB on-chip SRAM cache for caching bounds-information. Our mechanism allows detection of out-of-bounds errors in user-code as well as in unmodified shared-library functions. Our mechanism has detected out-of-bounds accesses in 87 lines of code in the SPEC CPU 2017 benchmarks, primarily in Glibc v2.27 functions, that, to our knowledge, have not been previously detected even with popular tools like Address Sanitizer.

years, of whom 542 were followed up for a median follow-up period of 24 months. All participants underwent body composition measurements, and they were grouped by sex and presence of sarcopenia using the Framingham risk model to assess their 10-year cardiovascular risk. According to the changes in the cardiovascular risk during follow-up, the patients were divided into four groups: low-low, low-high, high-low, and high-high. Results. The prevalence of anemia was higher in the sarcopenia group than in the nonsarcopenia group (11.5% vs. 24.1% for men,

In follow-up studies, sarcopenia was associated with an increased risk of CVD at 10 years, and a reduction in appendicular skeletal muscle mass index independently predicted the increased risk of CVD. Conclusion. Sarcopenia is associated with an increased risk of anemia, and the presence of both has an additive effect on the 10-year CVD risk in patients with type 2 diabetes. Loss of muscle mass can independently predict an increased CVD risk in diabetic patients.

Abstract

Genome-wide association studies (GWAS) have revealed numerous genetic loci associated with colorectal cancer risk, but the mechanisms underlying these loci have not been comprehensively elucidated. In this study, we performed a GWAS meta-analysis with a two-stage replication strategy by combining eight colorectal cancer cohorts encompassing 7,186 cases and 8,512 controls in Chinese populations, accompanied by an evaluation encompassing 29,832 cases and 406,694 controls in European populations. The genetic variant rs505706 A&gt;G, located at chr1q44 in the upstream region of catsper channel auxiliary subunit epsilon (CATSPERE), was associated with colorectal cancer risk and exhibited genome-wide significance (OR, 0.73; 95% confidence interval, 0.67–0.80; P = 9.75 × 10–12). Cell line and animal models were applied to assess the biological function of the genetic risk variant and the corresponding susceptibility gene. Genetically, the G allele of rs505706 resulted in long-range regulatory effects, reducing the binding affinity of POU2F1 for the CATSPERE promoter and thus abolishing the inhibitory effect of POU2F1 on CATSPERE transcription. Phenotypically, CATSPERE upregulation attenuated tumor growth in both colorectal cancer cells and xenograft models. Mechanistically, CATSPERE promoted calcium ion influx and apoptotic pathway activity. In zebrafish models, CATSPERE exerted pleiotropic effects, enhancing the progression of colorectal cancer. Collectively, these findings highlight a colorectal cancer susceptibility locus that acts to remotely modulate the activity of CATSPERE, a gene that mediates multiple functions involved in colorectal tumorigenesis and progression.

Significance:
A GWAS meta-analysis identifies a novel susceptibility locus harboring a genetic risk variant that mediates pleiotropic biological effects in colorectal tumorigenesis and progression.
CKGSE: A Prototype Search Engine for Chinese Knowledge

Published: January 2022

Abstract
Nowadays, with increasing open knowledge graphs (KGs) being published on the Web, users depend on open data portals and search engines to find KGs. However, existing systems provide search services and present results with only metadata while ignoring the contents of KGs, i.e., triples. It brings difficulty for users' comprehension and relevance judgement. To overcome the limitation of metadata, in this paper we propose a content-based search engine for open KGs named CKGSE. Our system provides keyword search, KG snippet generation, KG profiling and browsing, all based on KGs' detailed, informative contents rather than their brief, limited metadata. To evaluate its usability, we implement a prototype with Chinese KGs crawled from OpenKG.CN and report some preliminary results and findings.
Meta-Art History: Introduction to a Narratological Study of Art History
Authors: Duan Lian 
Published: January 2022

Abstract
This article outlines a narratological study of art history, discussing how to tell the story of art while telling the story. With this twofold purpose in mind, the author in this article draws the grande ligne of a narrative model on the one hand and proposes a historical argument about modern Chinese art on the other. The former aims at breaking down the boundary between intrinsic and extrinsic studies of art history, whereas the latter aims at proposing a main thesis about modern Chinese art. For the main thesis, the author argues that the development of Chinese art in the twentieth and the early twenty-first centuries is primarily determined by the interaction between the influence of Western art and the Chinese responses to the influence, and the response is driven by the Chinese anxiety of cultural identity over the last one hundred years. Although the topic of this article is centralized around modern Chinese art, the theorization of the methodological approach is to generalize the narrative model for the study of not only art history but also visual culture, critical theory, and relevant disciplines in the humanities.
The Mode of Textual Existence in Communicative Narratology
Authors: Wang Weiyan 
Published: January 2022

Abstract
In communicative narratology, narrative texts are not cut and dry. Some of them indicate the mutual recognition between utterers and receivers, thus forming universal bidirectional texts; others rely on receivers’ subsequent confirmation, forming unidirectional texts. Despite the different types, texts are essentially formulated via both sides of communication, which secondary narrativization pervades. Indeed, this secondary narrativization entails the process of ‘re-textualization’, eventually forming a ‘secondary text’. It remains, in most cases, a type of ‘abstract’ text, which will not become tangible until it is embodied in signs.
Climate Change Fosters Competing Effects of Dynamics and Thermodynamics in Seasonal Predictability of Arctic Sea Ice
Authors: Polyakov Igor V. , Mayer Michael , Tietsche Steffen , Karpechko Alexey Yu. 
Published: January 2022

Abstract
The fast decline of Arctic sea ice necessitates a stronger focus on understanding the Arctic sea ice predictability and developing advanced forecast methods for all seasons and for pan-Arctic and regional scales. In this study, the operational forecasting system combining an advanced eddy-permitting ocean–sea ice ensemble reanalysis ORAS5 and state-of-the-art seasonal model-based forecasting system SEAS5 is used to investigate effects of sea ice dynamics and thermodynamics on seasonal (growth-to-melt) Arctic sea ice predictability in 1993–2020. We demonstrate that thermodynamics (growth/melt) dominates the seasonal evolution of mean sea ice thickness at pan-Arctic and regional scales. The thermodynamics also dominates the seasonal predictability of sea ice thickness at pan-Arctic scale; however, at regional scales, the predictability is dominated by dynamics (advection), although the contribution from ice growth/melt remains perceptible. We show competing influences of sea ice dynamics and thermodynamics on the temporal change of ice thickness predictability from 1993–2006 to 2007–20. Over these decades, there was increasing predictability due to growth/melt, attributed to increased winter ocean heat flux in both Eurasian and Amerasian basins, and decreasing predictability due to advection. Our results demonstrate an increasing impact of advection on seasonal sea ice predictability as the region of interest becomes smaller, implying that correct modeling of sea ice drift is crucial for developing reliable regional sea ice predictions. This study delivers important information about sea ice predictability in the “new Arctic” conditions. It increases awareness regarding sea ice state and implementation of sea ice forecasts for various scientific and practical needs that depend on accurate seasonal sea ice forecasts.
Development of the Yearly Mode-1 M2 Internal Tide Model in 2019
Authors: Zhao Zhongxiang 
Published: January 2022

Abstract
The yearly mode-1 M2 internal tide model in 2019 is constructed using sea surface height measurements made by six concurrent satellite altimetry missions: Jason-3, Sentinel-3A, Sentinel-3B, CryoSat-2, Haiyang-2A, and SARAL/AltiKa. The model is developed following a three-step procedure consisting of two rounds of plane wave analysis with a spatial bandpass filter in between. Prior mesoscale correction is made on the altimeter data using AVISO gridded mesoscale fields. The model is labeled Y2019, because it represents the 1-yr-coherent internal tide field in 2019. In contrast, the model developed using altimeter data from 1992 to 2017 is labeled MY25, because it represents the multiyear-coherent internal tide field in 25 years. Thanks to the new mapping technique, model errors in Y2019 are as low as those in MY25. Evaluation using independent altimeter data confirms that Y2019 reduces slightly less variance (∼6%) than MY25. Further analysis reveals that the altimeter data from five missions (without Jason-3) can yield an internal tide model of almost the same quality. Comparing Y2019 and MY25 shows that mode-1 M2 internal tides are subject to significant interannual variability in both amplitude and phase, and their interannual variations are a function of location. Along southward internal tides from Amukta Pass, the energy flux in Y2019 is 2 times larger and the phase speed is about 1.1% faster. This mapping technique has been applied successfully to 2017 and 2018. This work demonstrates that yearly internal tides can be observed by concurrent altimetry missions and their interannual variations can be determined.

Significance Statement
This work is motivated to study the interannual variations of internal tides using observation-based yearly internal tide models from satellite altimetry. Previous satellite observations of internal tides are usually based on 25 years of altimeter data from 1993 to 2017. The yearly subsetted altimeter data are short, so that the resultant yearly models are overwhelmed by noise. A new mapping technique is developed and demonstrated in this paper. It paves a path to study the interannual and decadal variations of internal tides on a global scale and monitor the global ocean changes by tracking long-range internal tides.
A Simple Model for Predicting the Tropical Cyclone Radius of Maximum Wind from Outer Size
Authors: Chavas Daniel R. , Knaff John A. 
Published: January 2022

Abstract
The radius of maximum wind (Rmax) in a tropical cyclone governs the footprint of hazards, including damaging wind, surge, and rainfall. However, Rmax is an inconstant quantity that is difficult to observe directly and is poorly resolved in reanalyses and climate models. In contrast, outer wind radii are much less sensitive to such issues. Here we present a simple empirical model for predicting Rmax from the radius of 34-kt (1 kt ≈ 0.51 m s−1) wind (R17.5 ms). The model only requires as input quantities that are routinely estimated operationally: maximum wind speed, R17.5 ms, and latitude. The form of the empirical model takes advantage of our physical understanding of tropical cyclone radial structure and is trained on the Extended Best Track database from the North Atlantic 2004–20. Results are similar for the TC-OBS database. The physics reduces the relationship between the two radii to a dependence on two physical parameters, while the observational data enables an optimal estimate of the quantitative dependence on those parameters. The model performs substantially better than existing operational methods for estimating Rmax. The model reproduces the observed statistical increase in Rmax with latitude and demonstrates that this increase is driven by the increase in R17.5 ms with latitude. Overall, the model offers a simple and fast first-order prediction of Rmax that can be used operationally and in risk models.

Significance Statement
If we can better predict the area of strong winds in a tropical cyclone, we can better prepare for its potential impacts. This work develops a simple model to predict the radius where the strongest winds in a tropical cyclone are located. The model is simple and fast and more accurate than existing models, and it also helps us to understand what causes this radius to vary in time, from storm to storm, and at different latitudes. It can be used in both operational forecasting and models of tropical cyclone hazard risk.
Preference Distortion, Information Cost and Comparative Advantage: A Theoretical Quest to Claim Trade Posture in Post-Pandemic Era
Authors: Chatterjee Tonmoy , Dinda Soumyananda 
Published: January 2022

This study argues that post-pandemic world may not necessarily follow the usual mechanism of trade. In fact, recent pandemic dragged down us to the trajectory of new normalcy. Economic behaviour under new normalcy has changed immensely following several distorted effects, namely preference distortion and information asymmetry. Such distortions change trade posture via gains from trade arguments under comparative advantage. Using the traditional Ricardian model with two countries, two goods and one factor, this study explores the effect of changes in consumer preferences on trade patterns based on comparative advantage and the significance of eliminating information uncertainty. To retain the pre-pandemic gains from such trade this study advocates for consideration of information cost associated with trade basket along with innovation. These results could be important for policymaking at least in post pandemic regime. Sensitivity analysis has also been constructed to capture the extent of changes in trade–autarky profit gaps. This study builds on the verge of economic crisis linking to pandemic and international trade. JEL Codes: C70, D81, F11, L15

Published: January 2022

Background The pulmonary artery area (PAA) is a valuable non-invasive method for the diagnosis of pulmonary hypertension. Purpose To compare the change in PAA in patients with COVID-19 with the computed tomography (CT) severity index using follow-up imaging. Material and Methods A total of 81 patients who were followed up and underwent CT assessment more than once at our hospital‘s pandemic department were evaluated retrospectively. Patients with progression were separated into three groups: progression ranging from mild-to-mild infiltration (Group A, CT severity index of 0–2); progression from mild to severe infiltration (Group B, CT severity index of 0-2 to 3–5); and progression from severe-to-severe infiltration (Group C, CT severity index of 3–5). The PAAs were calculated separately. Results The mean age was 56 ± 12 years. In terms of those patients showing progression in the CT images, the number of patients in Groups A, B, and C was 29, 40, and 12 in the right lung; 32, 45, and 4 in the left lung; 23, 45, and 13 on both lungs, respectively. There was no significant difference between the main, right, and left PAAs in Group A ( P > 0.05). In Group B, there were significant increases in the areas of the main, right, and left PAAs ( P < 0.05). There were also significant increases in the areas of the right and main pulmonary arteries in Group C ( P < 0.05). Conclusion PAAs increase as disease involvement advances in cases with COVID-19 pneumonia, which is thought to be correlated with progression.

Published: January 2022

Welding fumes contain a complex mixture of metallic oxides that pose a risk to welders' respiratory systems. This study aimed to evaluate respiratory health disorders among workers in some Egyptian welding enterprises and their relationship to the workplace environment. This research was performed from January 1st, 2019 to February 28th, 2021 in welding enterprises in Birket El-Sabaa, a randomly selected district of Menoufia governorate, Egypt. A cross-sectional comparative study was conducted on 110 welders and 110 non-occupationally exposed subjects. Environmental studies were carried out for total welding fumes, respirable dust, and manganese air levels. Spirometric measures and manganese levels in whole blood were applied. Analysis of the personal air samples revealed that the mean values of welding fumes, respirable dust, and manganese air levels were higher than the international permissible levels. Welders had a higher significant prevalence of respiratory manifestations (rhinitis, cough, expectoration, wheezes, dyspnea, and chronic bronchitis) as well as decreased spirometric measures (FVC%, FEV1%, FEV1/FVC%, and FEF25-75%) than controls. The mean value of whole blood manganese level was statistically significantly higher among welders than that of the controls (3.35 ± 0.5 and 1.81 ± 0.79 ng/mL; respectively). A significant relationship was reported between longer work time and the prevalence of respiratory manifestations and decreased spirometric measurements. The use of masks/respirators was associated with a reduced prevalence of respiratory manifestations. Finally, welders that are exposed to welding fumes at concentrations higher than the permissible levels in welding establishments suffer from adverse respiratory problems, as shown by increased prevalence of respiratory manifestations and lower spirometric measurements. Regular use of high-quality personal protective equipment, especially masks, as well as periodic medical examinations for welders, is highly urged.
Which is your favorite music genre? A validity comparison of Facebook data and survey data
Authors: Kmetty Zoltán , Németh Renáta 
Published: January 2022

In this study, we use a parallel mixed-method data collection: a face-to-face survey combined with personal Facebook data archive collection. Our paper is the first attempt to cross-validate the self-reported musical preference with Facebook-based music preference classification. We primarily focused on operationalization-related questions and validity issues. The results overall showed that the different measures have only moderate correlations with each other. Some genres measured similarly, but there were significant differences too. A good example of the latter is world-music. It was the second most preferred genre of the survey, but based on FB data it was at the lower end of the preference scale. Digital data opens the possibility of examining topics we could not investigate, and re-examining topics with new approaches. However, all the data sources have their validity problems, and we need to consider many factors before we select a data source for analysis.
