Privacy-preserving Web single sign-on: Formal security analysis and design
Authors: Schmitz Guido 
Published: February 2022

Abstract
Single sign-on (SSO) systems, such as OpenID and OAuth, allow Web sites to delegate user authentication to third parties, such as Facebook or Google. These systems provide a convenient mechanism for users to log in and ease the burden of user authentication for Web sites. Conversely, by integrating such SSO systems, they become a crucial part of the security of the modern Web.
So far, it has been hard to prove if Web standards and protocols actually meet their security goals. SSO systems, in particular, need to satisfy strong security and privacy properties. In this thesis, we develop a new systematic approach to rigorously and formally analyze and verify such strong properties with the Web Infrastructure Model (WIM), the most comprehensive model of the Web infrastructure to date.
Our analyses reveal severe vulnerabilities in SSO systems that lead to critical attacks against their security and privacy. We propose fixes and formally verify that our proposals are sufficient to establish security. Our analyses, however, also show that even Mozilla’s proposal for a privacy-preserving SSO system does not meet its unique privacy goal. To fill this gap, we use our novel approach to develop a new SSO system, SPRESSO, and formally prove that our system indeed enjoys strong security and privacy properties.

Numerical and experimental formability analysis of aluminum 3105 sandwich panels produced by continuous hot-press forming
Authors: Elibol Cagatay , Wapande Sadam Hamis 
Published: February 2022

AbstractAluminum–plastic composites as building materials are widely used for different construction purposes, for instance, for exterior wall cladding, ventilated facades, and interior decoration of buildings, in billboards, trains, and automotive industry. The main goal of this study is to investigate the formability of AA3105/LDPE/AA3105 sandwich composite in detail, which would exhibit a higher formability compared to AA3105 due to its higher strain rate sensitivity and strain hardening exponent. This is of decisive importance for the manufacturing process. The Nakajima tests are performed to experimentally determine the forming limit curves (FLCs) usingin situoptical technique digital image correlation. Furthermore, numerical simulations of Nakajima tests are conducted using a modified Gurson–Tvergaard–Needleman damage model to compare the numerically and experimentally determined FLCs. The results show that the sandwich composite underwent inhomogeneous deformation during the Nakajima test, and that the FLC has no typical patterns exhibited by metal sheets. The FLCs predicted by the numerical model used in this study exhibit a very good correlation with the FLCs determined experimentally. The results of the present study provide new insights into the analysis and understanding of the deformation behavior of the sandwich composite sheet that may undergo complex stress and strain states.
Characterization of Fe2B layers on ASTM A1011 steel and modeling of boron diffusion
Authors: Morgado-González Irving , Ortiz-Dominguez Martin , Keddam Mourad 
Published: February 2022

Abstract
In this work, the ASTM A1011 steel substrate has been pack-boronized in the interval of 1123–1273 K for 2–8 h. With the used powders mixture (33.5 wt.% B4C, 5.4 wt.% KBF4 and 61.1 wt.% SiC), the iron boride layers were formed on this steel. The boronized layer/matrix was characterized by a jagged morphology. X-ray diffraction technique was used in order to identify the presence of iron boride phase. Tribological studies were also undertaken to assess the interfacial adherence of boride layer to the substrate and the values of coefficient of friction (COF) for borided and unborided samples. In addition, the mean diffusion coefficient approach was employed to estimate the diffusivity of boron in Fe2B. Moreover, this diffusion model has been verified empirically by using an extra boriding condition (at 1248 K for 2 h).
Effect of heat treatment on microstructure and properties of modified hypereutectic high chromium cast iron
Authors: Chen Zhengyang , Guo Qiang , Fu Hanguang , Zhi Xiaohui 
Published: February 2022

Abstract
The effect of heat treatment on the microstructure, hardness and wear resistance of modified hypereutectic high chromium cast iron (HCCI) was investigated. The results show that the quenching treatment partially dissolves the edges of the primary carbides, and the sharp corners become rounded and blunt. As the quenching temperature increases, the carbide re-dissolves into the matrix, and the hardness and wear resistance first increase and then decrease. The hardness and wear resistance are the best when quenched at 1000 °C. After tempering, the martensite is transformed into tempered martensite, and the precipitation of secondary carbides increases. As the tempering temperature increases, the secondary carbides gradually become coarser. When the tempering temperature is 500 °C, the hypereutectic HCCI shows the highest hardness and the best wear resistance. When tempered at 400 °C, hypereutectic HCCI shows the best erosion and wear resistance.

Published: February 2022

Abstract
Paper cultural relics are both precious, inheritable and fragile. However, with the passage of time, paper will also be affected by a variety of factors, and will appear mildew, yellow, brittle, or even completely damaged. In order to protect the cultural relics, extend lifespan paper, CMC-acrylate-OVPOSS graft copolymerization emulsion was synthesized by using carboxymethyl cellulose (CMC) as substrate, methyl methacrylate (MMA), butyl acrylate (BA), glycidyl methacrylate (GMA), hydroxyethyl methacrylate (HEMA), octavinyl polyhedral oligomeric silsesquioxane (OVPOSS) as graft copolymer. The CMC-acrylate-OVPOSS emulsion was coated on the surface of the paper to test its protective effect on the paper. The results showed that the mass concentration of 10 % reinforcement solution coated on the paper, mechanical properties of paper were greatly improved, and the gloss and whiteness of paper were slightly changed, the paper also had a certain aging resistance and acid and alkali corrosion resistance. At the same time, the reversibility experiment showed that the reinforcement material had a certain reversibility.
Ginsenoside-Mc1 reduces ischemia/reperfusion-induced cardiac arrhythmias through activating JAK2/STAT3 pathway and attenuating oxidative/endoplasmic reticulum stress in hyperlipidemic rats
Authors: Zhang Yanwei , Xu Kun , Zhang Yanqing 
Published: February 2022

Abstract

Objectives
Patients suffering from myocardial ischemia-reperfusion (IR) injuries usually have varying degrees of negatively-affecting comorbidities like hyperlipidemia. We evaluated the preconditioning effect of ginsenoside-Mc1 on reperfusion injury-induced myocardial arrhythmias, along with cardiac oxidative stress, endoplasmic reticulum stress protein expression, and histological damage in hyperlipidemic rats, and further, explore the role of JAK2/STAT3 activity.

Methods
Thirty-five Sprague–Dawley rats fed a high-fat diet for eight weeks. Ginsenoside-Mc1 (10 mg/dL, IP) was administered to hyperlipidemic rats daily for one month before IR injury. IR injury was induced by 35 min LAD coronary artery ligation and subsequent 60-min reperfusion. A selective JAK2 inhibitor (AG490) was injected before IR injury. Electrocardiography was recorded and myocardial arrhythmias (ventricular premature complexes, tachycardia, and fibrillation) were evaluated in the reperfusion phase according to Lambeth convention. Hematoxylin-Eosin staining, spectrophotometry, and Western blotting techniques were employed to measure the endpoints.

Results
IR injury in hyperlipidemic rats significantly increased the reperfusion-induced myocardial arrhythmias counts, timing, incidence, and severity. The expression of proteins of endoplasmic reticulum stress (p-PERK, p-eIF2α, CHOP), and oxidative stress marker malondialdehyde were significantly upregulated following IR induction, whereas antioxidant superoxide-dismutase and JAK2/STAT3 proteins expression significantly reduced, as compared with untreated-hyperlipidemic rats. Administration of ginsenoside-Mc1 to hyperlipidemic rats significantly corrected the arrhythmogenic feature of IR injury, reduced phosphorylation and expression of PERK, eIF2α, CHOP, and improved oxidative stress and histological changes. Interestingly, inhibition of the JAK2/STAT3 pathway via AG490 significantly abolished ginsenoside-Mc1-induced cardioprotection.

Conclusions
Taken together, ginsenoside-Mc1 exerts substantial anti-arrhythmogenic influences against myocardial IR injury in hyperlipidemic rats through activation of JAK2/STAT3 pathway and subsequent reduction of oxidative/endoplasmic reticulum stress.
Design of Internet of Things Information Interactive Perception System Based on 5G Mobile Communication Technology in a Hospital Network
Authors: Yang Xiuying , Chen Xiaohong 
Published: February 2022

Abstract
In the communication process of 5G big data Internet of Things, because of the difference of communication data, the data interaction process needs information mutual recognition scheduling, which greatly reduces the effectiveness of the interactive perception system. In order to improve the real-time performance of platform interaction in the Internet of Things environment, an Internet of Things information interaction perception system based on 5G mobile communication technology is designed. This is mainly important in a hospital network. The system perception layer completes the accurate acquisition of Internet of Things information through data acquisition module and transmits it to the application layer through 5G mobile communication module in the network layer. The intelligent interaction module based on context awareness in the application layer will be heterogeneous and unstructured. The Internet of Things perceived data is encapsulated in context as a unified data processing object of the Internet of Things. The context rule-matching algorithm based on Storm is used to achieve accurate matching between heterogeneous and unstructured perceptual data and rules, and an interactive perceptual parallel query scheduling strategy is used to achieve the optimal scheduling of information mutual perception in the Internet of Things. The results show that there is a positive correlation between the validity of sensing temperature information and the amount of sensing data. The average data processing delay of the system is stable at 50 ms, which meets the real-time requirement of data processing.

Penulisan ini bertujuan untuk mengetahui bagaimana praktik stringer dalam melaksanakan peliputan di Kota Bandung serta mengetahui bagaimana sikap stringer dalam memaknai profesinya. Metode penelitian menggunakan metode deskriptif kualitatif yang berusaha mendeskripsikan seluruh keadaan yang terjadi pada objek penelitian dengan menggunakan data dari hasil observasi serta wawancara bersama informan. Hasil penelitian menunjukan bahwa praktek stringer tidak hanya terjadi di daerah saja di kota besarpun praktek ini masih ditemukan. Meskipun dengan jumlah yang tidak banyak, di Kota Bandung sendiri terdapat 4-5 stringer yang masih aktif bekerja kepada kontributornya. Tugas dan peran stringer di lapangan sama seperti kontributor, hanya saja stringer tidak mendapatkan hak intelektual dalam pengakuan karya jurnalistiknya. Cara stringer memandang serta memaknai pekerjaannya menjadi bias, sebagian mereka menganggap sebagai hal positif namun sebagian lagi menganggap sebagai hal negatif. Menjadi seorang stringer dapat dijadikan kesempatan untuk mengasah kemampuan serta proses pembelajaran menjadi wartawan nantinya, namun pada prosesnya dilapangan menjadi seorang stringer akan banyak menemui permasalahan.Meskipun stringer banyak membantu kerja kontributor di lapangan, praktek mempekerjakan stringer telah menyalahi kode etik jurnalistik.

ABSTRACT
This paper aims to find out how practice stringers in carrying out coverage in the city of Bandung and find out how stringer’s attitude in interpreting his profession. This research method uses a qualitative descriptive. Descriptive method that attempts to describe all the conditions that occur in the object of research using data from observations and interviews with informant. The result showed that stringer practice did not only occur in regions in the big cities, but this practice was still found. Although there are not many, in Bandung there are 4-5 stringers who are still actively working with their contributors. The duties and role of stringers in the field are the same as contributors, only stringers do not get intellectual rights in recognition of their journalistic work. The way stringers look and interpret their work becomes based, some of them consider it positive but some consider it negative. A Stringer can be used as an opportunity to hone skills and as a learning process to become a journalist later, but many problems that occur in the process of working stringers in the field. Although stringers help contributors work a lot in the field, on the other hand the practice of employing stringers has violated the journalistic code of ethics.

Published: February 2022

ResumoO intenso processo de urbanização das últimas décadas levou à necessidade de implantação de infraestruturas, entre elas a infraestrutura viária. No Brasil a malha viária é responsável pela maior parte do transporte de cargas e pessoas. Em função dos custos envolvidos em uma obra de pavimentação, o objetivo principal deste trabalho foi a otimização do custo de um pavimento flexível, considerando o tipo de estrutura, as espessuras das camadas e o valor dos materiais empregados. Para tanto, as estruturas foram dimensionadas a partir do Método de Projeto de Pavimentos Flexíveis (DNER, 1981) e com a utilização da ferramenta Solver do Microsoft Excel. Para a realização das análises manteve-se fixo o Número N, as Distâncias Médias de Transporte e os custos envolvidos no processo, já os valores de CBR de subleito e reforço de subleito foram variados. Na maioria dos casos estudados a estrutura constituída por revestimento, base e reforço de subleito mostrou-se mais econômica que as demais. Além disso, a utilização da ferramenta Excel Solver implicou em um menor custo total de pavimento apenas quando o CBR do reforço de subleito é menor que 12%, nas demais situações não houve diferença entre o método do DNER e o dimensionamento feito pelo Solver.

In Brazil, the road network is responsible for most of the transportation of cargo and people. Because of the costs involved in a paving work, the main objective of this paper was to optimize the cost of a flexible pavement, considering the type of structure, the thickness of the layers and the value of the materials used. For that, the structures were dimensioned using the Flexible Pavement Design Method (DNER, 1981) and using the Microsoft Excel Solver tool. In order to carry out the analyzes, the Number N, the Average Transport Distances and the costs involved in the process remained fixed, since the CBR values of subgrade and subgrade reinforcement were varied. In most of the cases studied, the structure consisting of surface course, base course and subgrade reinforcement proved to be more economical than the others. In addition, the use of the Excel Solver tool resulted in a lower total pavement cost only when the CBR of the subgrade reinforcement is less than 12%, in the other situations there was no difference between the DNER method and the design made by Solver.
