Abstract Single Sign-On (SSO) decreases the complexity and eases the burden of managing many accounts with a single authentication mechanism. Mission critical application such as banking demands highly trusted identity provider to authenticate its users. The existing SSO protocol such as OpenID Connect protocol provides secure SSO but it is applicable only in the consumer-to-social-network scenarios. Owing to stringent security requirements, the SSO for banking service necessitates a highly trusted identity provider and a secured private channel for user access. The banking system depends on a dedicated central banking authority which controls the monetary policy and it must assume the role of the identity provider. This paper proposes an extension of OpenID Connect protocol that establishes a central identity provider for bank users, which facilitates the users to access different accounts using single login information. The proposed Enhanced OpenID Connect (EOIDC) modifies the authorization code flow of OpenID Connect to build a secure channel from a single trusted identity provider that supports multiple banking services. Moreover, the EOIDC tightens the security mechanism with the help of SAT to avoid impersonation attack using replay and redirect. The formal security analysis and validation demonstrate the strength of the EOIDC against possible attacks such as impersonation, eavesdropping, and a brute force login. The experimental results reveal that the proposed EOIDC system is efficient in providing secured SSO protocol for banking services.

Full textAbstract:
Identity federation allows one to link a user’s digital identities across several identity management systems. Federated identity management (FIM) ensures that users have easy access to the available resources. However, scaling FIM to numerous partners is a challenging process due to the interoperability issue between different federation architectures. This study proposes a dynamic identity federation model to eliminate the manual configuration steps needed to establish an organizational identity federation by utilizing the OpenID Connect (OIDC) framework. The proposed model consists of three major steps to establish dynamic FIM: first, the discovery of the OpenID service provider, which indicates the location of the partner organization; second, the registration of the OpenID relying party, which allows the organization and its partner to negotiate information for establishing the federation; finally, establishing the dynamic trust federation. The proposed dynamic FIM model allows applications to provide services to end-users coming from various domains while maintaining a trust between clients and service providers. Through our proposed dynamic identity federation model, organizations can save hundreds of hours by achieving dynamic federation in runtime and serving a large number of end-users.

Full textAbstract:
Increase in the number of users is directly proportional to the need of verifying them. This means that any user using any website or application has to be authenticated first; this leads to the creation of multiple credentials of one user. Now if these different websites or applications are connected or belong to one single organization like a college or school, a lot of redundancy of data is there. Along with this, each user has to remember a wide range of credentials for different applications/websites. So in this paper, we address the issue of redundancy and user related problems by introducing SSO using OpenId Connect in educational institutes. We aim to mark the difference between the traditional system and proposed login by testing it on a group of users.

Full textAbstract:
Specifications such as SAML, OAuth, OpenID Connect and Mobile Connect are essential for solving identification, authentication and authorisation in contexts such as mobile apps, social networks, e-commerce, cloud computing or the Internet of Things. However, end-users relying on identity providers to access resources, applications or services lose control over the Personally Identifiable Information (PII) they share with the different providers composing identity federations. This work proposes a user-centric approach based on a recommendation system to support users in making privacy decisions such as selecting service providers or choosing their privacy settings. The proposed Privacy Advisor gives end-users privacy protection by providing personalised recommendations without compromising the identity federations’ functionalities or requiring any changes in their underlying specifications. A proof of concept of the proposed recommendation system is presented to validate and evaluate its utility and feasibility.

Abstract Authentication delegation is a major function of the modern web. Identity Providers (IdP) acquired a central role by providing this function to other web services. By knowing which web services or web applications access its service, an IdP can violate the enduser privacy by discovering information that the user did not want to share with its IdP. For instance, WebRTC introduces a new field of usage as authentication delegation happens during the call session establishment, between two users. As a result, an IdP can easily discover that Bob has a meeting with Alice. A second issue that increases the privacy violation is the lack of choice for the end-user to select its own IdP. Indeed, on many web-applications, the end-user can only select between a subset of IdPs, in most cases Facebook or Google. In this paper, we analyze this phenomena, in particular why the end-user cannot easily select its preferred IdP, though there exists standards in this field such as OpenID Connect and OAuth 2? To lead this analysis, we conduct three investigations. The first one is a field survey on OAuth 2 and OpenID Connect scope usage by web sites to understand if scopes requested by websites could allow for user defined IdPs. The second one tries to understand whether the problem comes from the OAuth 2 protocol or its implementations by IdP. The last one tries to understand if trust relations between websites and IdP could prevent the end user to select its own IdP. Finally, we sketch possible architecture for web browser based identity management, and report on the implementation of a prototype.

The File Transfer Service (FTS) developed at CERN and in production since 2014, has become a fundamental component for the LHC experiments and is tightly integrated with experiment frameworks. Starting from the beginning of 2018 with the participation to the European Commission funded project eXtreme Data Cloud (XDC) and the activities carried out in the context of the WLCG DOMA TPC and QoS working groups, a series of new developments and improvements have been planned and performed taking also into account the requirements from the experiments in preparation for the LHC Run-3. This paper provides a detailed overview of these developments; more specifically, the integration with OpenID Connect (OIDC), the QoS integration, the service scalability enhancements, the support for XRootD and HTTP Third Party Copy (TPC) transfers along with the integration with the new CERN Tape Archive (CTA) system.

In this manuscript, we describe the soft- and hardware architecture as well as the implementation of a modern Internet of Medical Things (IoMT) system for sensor-assisted telepsychotherapy. It enables telepsychotherapy sessions in which the patient exercises therapy-relevant behaviors in their home environment under the remote supervision of the therapist. Wearable sensor information (electrocardiogram (ECG), movement sensors, and eye tracking) is streamed in real time to the therapist to deliver objective information about specific behavior-triggering situations and the stress level of the patients. We describe the IT infrastructure of the system which uses open standards such as WebRTC and OpenID Connect (OIDC). We also describe the system’s security concept, its container-based deployment, and demonstrate performance analyses. The system is used in the ongoing study SSTeP-KiZ (smart sensor technology in telepsychotherapy for children and adolescents with obsessive-compulsive disorder) and shows sufficient technical performance.

The objective of this paper is to provide an online registration system for covid-19 vaccination. In this crisis, it will be difficult to register in person and get vaccinated after waiting in a queue for a long period; thus, registering online is the safest and most convenient way to schedule slots on a convenient date and get vaccinated. We built this application using spring boot, which allows developers to directly get into coding without wasting time in setting up and configuring the environment. For authentication and authorization, we integrated it with keycloak, a third-party service, which is a simple way to make our webbased apps more secure and Keycloak provides distinctive features to the application like single Single-Sign On, OpenID Connect Support, Social Logins and many more. So, this is a web-based service where any individual can conveniently schedule their slots from anywhere according to the availability in their desired locations.

The EU-funded ESCAPE project aims at enabling a prototype federated storage infrastructure, a Data Lake, that would handle data on the exabyte-scale, address the FAIR data management principles and provide science projects a unified scalable data management solution for accessing and analyzing large volumes of scientific data. In this respect, data transfer and management technologies such as Rucio, FTS and GFAL are employed along with monitoring enabling solutions such as Grafana, Elasticsearch and perf- SONAR. This paper presents and describes the technical details behind the machinery of testing and monitoring of the Data Lake – this includes continuous automated functional testing, network monitoring and development of insightful visualizations that reflect the current state of the system. Topics that are also addressed include the integration with the CRIC information system as well as the initial support for token based authentication / authorization by using OpenID Connect. The current architecture of these components is provided and future enhancements are discussed.

Since its earliest days, the Worldwide LHC Computational Grid (WLCG) has relied on GridFTP to transfer data between sites. The announcement that Globus is dropping support of its open source Globus Toolkit (GT), which forms the basis for several FTP client and servers, has created an opportunity to reevaluate the use of FTP. HTTP-TPC, an extension to HTTP compatible with WebDAV, has arisen as a strong contender for an alternative approach. In this paper, we describe the HTTP-TPC protocol itself, along with the current status of its support in different implementations, and the interoperability testing done within the WLCG DOMA working group’s TPC activity. This protocol also provides the first real use-case for token-based authorisation for this community. We will demonstrate the benefits of such authorisation by showing how it allows HTTP-TPC to support new technologies (such as OAuth, OpenID Connect, Macaroons and SciTokens) without changing the protocol. We will also discuss the next steps for HTTP-TPC and the plans to use the protocol for WLCG transfers.

One of the key challenges identified by the HEP R&D roadmap for software and computing is the ability to integrate heterogeneous resources in support of the computing needs of HL-LHC. In order to meet this objective, a flexible Authentication and Authorization Infrastructure (AAI) has to be in place, to allow the secure composition of computing and storage resources provisioned across heterogeneous providers (e.g., Grid, private and commercial Clouds, HPC centers). At CHEP 2018, we presented how a flexible AAI based on modern, standard Web technologies (OpenID Connect, OAuth and JSON Web Tokens) and centered on the INDIGO Identity and Access Management (IAM) service could support the transition of the WLCG infrastructure to a token-based AAI. In the meanwhile, INDIGO IAM has been selected by the WLCG Management Board as the solution that will be adopted by LHC experiments, and is also at the core of the AAI envisioned to support the computing needs of the ESCAPE project. In this contribution, which represents a follow up to last-year plenary talk, we describe the work done recently on the IAM service to support WLCG requirements.

At the end of May 2017 the Globus Alliance announced that the open-source Globus Toolkit (GT) would be no longer supported by the Globus team at the University of Chicago. This announcement had an obvious impact on WLCG, given the central role of the Globus Security Infrastructure (GSI) and GridFTP in the WLCG data management framework, so discussions started in the appropriate forums on the search for alternatives. At the same time, support for token-based authentication and authorization has emerged as a key requirement for storage elements powering WLCG data centers. In this contribution, we describe the work done to enable token-based authentication and authorization in the StoRM WebDAV service, describing and highlighting the differences between support for external OpenID connect providers, groupbased and capability-based authorization schemes, and locally-issued authorization tokens. We discuss how StoRM WebDAV token-based authorization is being exploited in several contexts, from WLCG DOMA activities to other scientific experiments hosted at the INFN Tier-1 data center. In this contribution, we also describe the methodology used to compare Globus GridFTP and StoRM WebDAV and we present initial results confirming how HTTP represent a viable alternative to GridFTP for data transfers also performance-wise.

The microservice architectural style splits an application into small services, which are implemented independently, with their own deployment unit. This architecture can bring benefits, nevertheless, it also poses challenges, especially about security aspects. In this case, there are several microservices within a single system, it represents an increase in the exposure of the safety surface, unlike the monolithic style, there are several applications running independently and must be secured individually. In this architecture, microservices communicate with each other, sometimes in a trust relationship. In this way, unauthorized access to a specific microservice could compromise an entire system. Therefore, it brings a need to explore knowledge about issues of security in microservices, especially in aspects of authentication and authorization. In this work, a Systematic Literature Review is carried out to answer questions on this subject, involving aspects of the challenges, mechanisms and technologies that deal with authentication and authorization in microservices. It was found that there are few studies dealing with the subject, especially in practical order, however, there is a consensus that communication between microservices, mainly due to its individual and trustworthy characteristics, is a concern to be considered. To face the problems, mechanisms such as OAuth 2.0, OpenID Connect, API Gateway and JWT are used. Finally, it was found that there are few open-source technologies that implement the researched mechanisms, with some mentions of the Spring Framework.

The EGI Cloud Compute service offers a multi-cloud IaaS federation that brings together research clouds as a scalable computing platform for research accessible with OpenID Connect Federated Identity. The federation is not limited to single sign-on, it also introduces features to facilitate the portability of applications across providers: i) a common VM image catalogue VM image replication to ensure these images will be available at providers whenever needed; ii) a GraphQL information discovery API to understand the capacities and capabilities available at each provider; and iii) integration with orchestration tools (such as Infrastructure Manager) to abstract the federation and facilitate using heterogeneous providers. EGI also monitors the correct function of every provider and collects usage information across all the infrastructure. DODAS (Dynamic On Demand Analysis Service) is an open-source Platform-as-a-Service tool, which allows to deploy software applications over heterogeneous and hybrid clouds. DODAS is one of the so-called Thematic Services of the EOSC-hub project and it instantiates on-demand container-based clusters offering a high level of abstraction to users, allowing to exploit distributed cloud infrastructures with a very limited knowledge of the underlying technologies.This work presents a comprehensive overview of DODAS integration with EGI Cloud Federation, reporting the experience of the integration with CMS Experiment submission infrastructure system.

PURPOSE Zero-footprint Web architecture enables imaging applications to be deployed on premise or in the cloud without requiring installation of custom software on the user’s computer. Benefits include decreased costs and information technology support requirements, as well as improved accessibility across sites. The Open Health Imaging Foundation (OHIF) Viewer is an extensible platform developed to leverage these benefits and address the demand for open-source Web-based imaging applications. The platform can be modified to support site-specific workflows and accommodate evolving research requirements. MATERIALS AND METHODS The OHIF Viewer provides basic image review functionality (eg, image manipulation and measurement) as well as advanced visualization (eg, multiplanar reformatting). It is written as a client-only, single-page Web application that can easily be embedded into third-party applications or hosted as a standalone Web site. The platform provides extension points for software developers to include custom tools and adapt the system for their workflows. It is standards compliant and relies on DICOMweb for data exchange and OpenID Connect for authentication, but it can be configured to use any data source or authentication flow. Additionally, the user interface components are provided in a standalone component library so that developers can create custom extensions. RESULTS The OHIF Viewer and its underlying components have been widely adopted and integrated into multiple clinical research platforms (e,g Precision Imaging Metrics, XNAT, LabCAS, ISB-CGC) and commercial applications (eg, Osirix). It has also been used to build custom imaging applications (eg, ProstateCancer.ai, Crowds Cure Cancer [presented as a case study]). CONCLUSION The OHIF Viewer provides a flexible framework for building applications to support imaging research. Its adoption could reduce redundancies in software development for National Cancer Institute–funded projects, including Informatics Technology for Cancer Research and the Quantitative Imaging Network.

Abstract Motivation Large biomedical datasets, such as those from genomics and imaging, are increasingly being stored on commercial and institutional cloud computing platforms. This is because cloud-scale computing resources, from robust backup to high-speed data transfer to scalable compute and storage, are needed to make these large datasets usable. However, one challenge for large-scale biomedical data on the cloud is providing secure access, especially when datasets are distributed across platforms. While there are open Web protocols for secure authentication and authorization, these protocols are not in wide use in bioinformatics and are difficult to use for even technologically sophisticated users. Results We have developed a generic and extensible approach for securely accessing biomedical datasets distributed across cloud computing platforms. Our approach combines OpenID Connect and OAuth2, best-practice Web protocols for authentication and authorization, together with Galaxy (https://galaxyproject.org), a web-based computational workbench used by thousands of scientists across the world. With our enhanced version of Galaxy, users can access and analyze data distributed across multiple cloud computing providers without any special knowledge of access/authorization protocols. Our approach does not require users to share permanent credentials (e.g. username, password, API key), instead relying on automatically generated temporary tokens that refresh as needed. Our approach is generalizable to most identity providers and cloud computing platforms. To the best of our knowledge, Galaxy is the only computational workbench where users can access biomedical datasets across multiple cloud computing platforms using best-practice Web security approaches and thereby minimize risks of unauthorized data access and credential use.

Digital transformation and the utilization of Industrial IoT (IIoT) introduces numerous interconnected devices to factories increasing among others the challenge of managing their software versions and giving attackers new possibilities to exploit various software vulnerabilities.
Factory networks were earlier isolated from the Internet. However, this separation is no longer valid and there can be connections that allow intruders to penetrate into information systems of factories. Another issue is that although factories typically are physically isolated, it is not necessarily safe to assume that physical security is in good shape as the novel supply networks comprise subcontracted activities and temporary work force. Another threat can also arise from unauthorized monitoring of devices and the unauthorized replacement of existing ones.
Based on the previous, it is crucial that IIoT security should be built into factories of the future (FoF) right from the design phase and even low-end devices need to be supported. Trusted computing concept called remote attestation should be used. Remote attestation allows remote parties to verify the integrity of each system component. System components should include trusted hardware components that can be used to measure executable software. The term measurement means calculating the cryptographic hash of the binary component before passing control to it. Trusted hardware components should also have a mechanism to protect the integrity of the measurement list and cryptographic keys that can be used to sign integrity assertions. The verifier part should have a storage of reference integrity metrics identifying the expected values of these measurements.
Deploying trusted computing and remote attestation concepts to industrial automation is not straightforward. Even if it is possible to use remote attestation with suitable hardware components, it is not clear how remote attestation should be integrated with various operational technology (OT) industrial automation protocols. Approaches to use remote attestation with existing industrial automation protocols (e.g., OPC UA) is discussed. Advanced identity and access management (e.g., OAuth2, OpenID Connect) can be used to combine integrity measurements with device identity information so that the remote attestation process is triggered by authentication during the first transaction. The focus is on machine-to-machine (M2M) communications with immutable device identities and integrity evidence transfer.

Full textAbstract:
This article explores how increased media access and use influences Kenyan women’s everyday life and alters the domestic space. Based on 30 in-depth interviews with women in Uasin Gishu County, Kenya, the article demonstrates that women have incorporated newly gained media into their daily lives and routines. Increased media access has opened up the home and turned the domestic sphere from a secluded place into a connected space in which women can receive input from, connect with and interact with the world beyond their immediate surroundings whilst simultaneously remaining at home and fulfilling their traditional gender roles. Women’s media use thus reinforces their connection to the domestic sphere and the gendered division of labour. Although it has the potential to challenge gender inequalities, the extent to which this occurs depends on the individual woman’s ability to act on the imaginaries and ideas that media carry.

Abstract: This research shows how to use colour and movement to automate the process of recognising and tracking things. Video tracking is a technique for detecting a moving object over a long distance using a camera. The main purpose of video tracking is to connect target objects in subsequent video frames. The connection may be particularly troublesome when things move faster than the frame rate. Using HSV colour space values and OpenCV in different video frames, this study proposes a way to track moving objects in real-time. We begin by calculating the HSV value of an item to be monitored, and then we track the object throughout the testing step. The items were shown to be tracked with 90 percent accuracy. Keywords: HSV, OpenCV, Object tracking, Video frames, GUI

Full textAbstract:
The emergence of social modernity in the Romanian principalities can be traced to the founding of quarantinist outposts against the last waves of plague and the first waves of cholera. The crisis of this sanitary arrangement opened the way for a series of failed but productive projects of modernization. The collective political body was imagined and created through the nationalization of the medical profession and the attempts to create a sanitary social body. The failure to connect urban and rural bodies inside a democratic all-embracing network opened up spaces for discourses questioning the identity of the collective body. Was there a “Romanian element”? What did that mean and was it degenerating? Demographic anti-Semitism and the first attempts to think of socioeconomic and sanitary failures in terms of racial degeneracy emerged from the fissures of the national sanitary system. Bacteriology was able to partially absorb these critiques and propose a larger interventionist project in the space opened by the old-style sanitary police.

Full textAbstract:
This qualitative research study was designed to explore the perceptions of parents with low income regarding the effects of involvement in a comprehensive preschool program on their children's development and on the families' quality of life. A purposeful sample of parents who became actively involved in the preschool community was interviewed about their experiences and the experiences of their children. These interviews were analyzed using the constant comparative method for emerging themes related to their experiences of the preschool. Parents' perspectives provided important insights into the processes that influence what they identified as positive outcomes. These insights, all connected to a larger theme of empowerment, included: (1) replacing isolation with affiliation, (2) increased self-confidence, (3) enhanced opportunity and ability to set goals and develop skills that promote self-sufficiency and goal attainment, and (4) empowering parents to empower their children through positive parenting. The evidence suggests that preschool structures and processes can enhance the development of the whole family by serving as a support system, and by nurturing relationships that are at the core of academic success. The study contributes to the research base on the effects of comprehensive preschool approaches to support families living in poverty.

Full textAbstract:
Alison & Peter Smithson's Economist Building in London (1960–1964) has been much written about, but one of its most distinctive features – the Roach bed Portland stone cladding – has been relatively little discussed. Although there have been various retrospective explanations for the choice of this previously unused stone, whose surface is marked by cavities of now vanished shells, no direct evidence from the time fully accounts for the decision. Reliance upon inference, and upon retrospective statements, mean that no definitive explanation for the choice is now possible. Some new evidence from archives and interviews, and a re-examination of the contemporary concerns of the Smithsons, and of their artist friends Eduardo Paolozzi and Nigel Henderson, fellow members of the Independent Group during the 1950s, however, suggest a plausible, though speculative, interpretation. When considered in light of the Smithsons' and their friends' interests in pattern, in hidden orders, and in the problems of ‘human association’, the choice of Roach bed Portland stone seems less surprising. More than just ‘pretty’, as Peter Smithson was later to describe the material, it can be seen to connect with a fascination with underlying, non-human, systems of order, while at the same time providing a particularly expressive form of protection for human identity in the modern city.

Full textAbstract:
Compelling research has documented how the circadian system is essential for the maintenance of several key biological processes including homeostasis, cardiovascular control, and glucose metabolism. Circadian clock disruptions, or losses of rhythmicity, have been implicated in the development of several diseases, premature ageing, and are regarded as health risks. Redox reactions involving reactive oxygen and nitrogen species (RONS) regulate several physiological functions such as cell signalling and the immune response. However, oxidative stress is associated with the pathological effects of RONS, resulting in a loss of cell signalling and damaging modifications to important molecules such as DNA. Direct connections have been established between circadian rhythms and oxidative stress on the basis that disruptions to circadian rhythms can affect redox biology, and vice versa, in a bi-directional relationship. For instance, the expression and activity of several key antioxidant enzymes (SOD, GPx, and CAT) appear to follow circadian patterns. Consequently, the ability to unravel these interactions has opened an exciting area of redox biology. Exercise exerts numerous benefits to health and, as a potent environmental cue, has the capacity to adjust disrupted circadian systems. In fact, the response to a given exercise stimulus may also exhibit circadian variation. At the same time, the relationship between exercise, RONS, and oxidative stress has also been scrutinised, whereby it is clear that exercise-induced RONS can elicit both helpful and potentially harmful health effects that are dependent on the type, intensity, and duration of exercise. To date, it appears that the emerging interface between circadian rhythmicity and oxidative stress/redox metabolism has not been explored in relation to exercise. This review aims to summarise the evidence supporting the conceptual link between the circadian clock, oxidative stress/redox homeostasis, and exercise stimuli. We believe carefully designed investigations of this nexus are required, which could be harnessed to tackle theories concerned with, for example, the existence of an optimal time to exercise to accrue physiological benefits.

Conditions of crisis can be fertile soil for social transformation. The Lovely Weather project in Donegal, northwest Ireland, brought artists into residence in localities where changing socio-economic and awareness of shifting environmental conditions opened up space for different cooperative relations. Donegal, bounded by the Atlantic, sitting between the north and south of Ireland, is an ambiguous in-between region with strong yet undervalued traditions relating to the sea and land. Drawing from a keynote presentation, this paper considers how residency models can dynamically connect poetics of place with broader environmental influences.

The fence is the main part of a house in terms of security. The conventional fence is opened and closed manually by the home owner. In rainy conditions this will be very ineffective and inefficient because the home owner has to get out of the vehicle to open the fence. This problem underlies the idea of making an automatic fence opening and closing system using a smartphone by utilizing Internet of Things (IoT) technology. Smartphone is useful as a NodeMCU controller contained in the ESP8266 WiFi module via an internet connection to connect to the blynk application. Relay is used as a switch that will command the motor to rotate when it gets a command from NodeMCU. Changes in relay conditions will cause the 12volt 200rpm DC motor to rotate, so the fence will move opened and closed. The movement of the servo motor also causes the turnstile to lock after the fence is closed. In order for the system to work properly, the revolutions per minute (RPM) of the motor requires a supply voltage of 12V. When the fence is opened, the motor speed is 53RPM. When closed, the motor speed is 49RPM. In the process of locking and opening the fence, the servo motor takes about 2 seconds.

The composite opened web steel joist supported floor systems have been common for many years. It is economic and has light weight and can embed the electrical conduit, ductwork and piping, eliminating the need for these to pass under the member, consequently eliminate the height between floors. In order to study the joist strength capacity under the various conditions, it had been fabricated seven joists composed of the steel and concrete slab connected to the top chord by shear connectors (headed studs). These joist have 2820 mm length c/c of the supports and 235 mm overall depth. In the present study, six variable parameters are adopted (Studs distribution, Degree of shear connection, Degree of the web inclination, Shape of the web, Density of concrete for slab and length of the shear connector). The test results exhibited that minimum strength capacity was 160kN for light weight joist and maximum capacity was 225kN for joist of long shear connectors at failure. The results were compared by ultimate flexural model by Azmi.

We describe two cases in which a biventricular implantable cardioverter defibrillator for cardiac resynchronization therapy had to be placed on the right side due to unsuitability of the left subclavian vein. Endocardial implantation of a left ventricular lead through the coronary sinus was previously attempted but was unsuccessful. Implantation of the epicardial left ventricular pacing lead was performed through video-assisted thoracic surgery on the left side. The connector end of the left ventricular pacing lead was tunnelized through the anterior mediastinum into the right pleural space. The right-sided pocket was then opened. A tunnel was created from the pocket to the thoracic wall, and the pleural space was entered over the second rib. The lead was retrieved from the right pleural space and connected with the Cardiac resynchronization therapy-device (CRT-D). Both procedures and postoperative periods were uneventful. Intrathoracic left-to-right tunneling of an epicardial left ventricular lead by video-assisted thoracic surgery is feasible and safe. It provides an alternative to subcutaneous tunneling.

In this work, we explore the possibility of leptogenesis beyond the standard Yukawa-mediated decays by considering a scenario where effective electromagnetic dipole operators that connect the light and heavy neutrinos play an important role. Through these operators, new decay channels for the postulated heavy neutrinos are opened up, and consequently, such L- and CP-violating processes can lead to the generation of the correct baryon asymmetry of the universe. In addition, it has been found that the relationship of the leptogenesis scale to the light neutrino masses is very similar to that for the standard leptogenesis setup.

Today's technology shows very significant developments in automation systems. Filling water in a tank is a process that is widely used in the oil industry. The process of filling and draining water in a closed water tank will raise difficulty for the operator to control the water level in the tank. Therefore, we will create a system to control the water level using a fuzzy controller. To get the value of fuzzification from the difference in the value of the set point and defuzzification connected to the motor pump. Fuzzy design system was obtained by making methods, fuzzification, defuzzification, and rules. The use of ultrasonic sensors during the experiment caused a spike in value because the ultrasonic sensor had not detected water but had no significant effect on the response to altitude levels. When the valve is opened, the controller has an effect on the resulting response. The more the valve is opened, the worse the response will be but the system remains stable. The fuzzy output will be connected to the PLC which will be connected to the Kepserver and tank to regulate the flow rate to the tank. Matlab is connected with PLC devices using Kepserver. The best performance is found in the 2× reduction valve opening response test with a fuzzification range of 8000-24000 while the performance value of time rise is 66.458 s, settling time is 110 s, steady state error is -2%, and overshoot is 9%.

Full textAbstract:
Intercellular bridges are a conserved feature of multicellular organisms. In multicellular fungi, cells are connected directly via intercellular bridges called septal pores. Using Aspergillus nidulans, we demonstrate for the first time that septal pores are regulated to be opened during interphase but closed during mitosis. Septal pore–associated proteins display dynamic cell cycle–regulated locations at mature septa. Of importance, the mitotic NIMA kinase locates to forming septa and surprisingly then remains at septa throughout interphase. However, during mitosis, when NIMA transiently locates to nuclei to promote mitosis, its levels at septa drop. A model is proposed in which NIMA helps keep septal pores open during interphase and then closed when it is removed from them during mitosis. In support of this hypothesis, NIMA inactivation is shown to promote interphase septal pore closing. Because NIMA triggers nuclear pore complex opening during mitosis, our findings suggest that common cell cycle regulatory mechanisms might control septal pores and nuclear pores such that they are opened and closed out of phase to each other during cell cycle progression. The study provides insights into how and why cytoplasmically connected Aspergillus cells maintain mitotic autonomy.

This application was created using features provided by the OpenCV library to produce binary images. Three main challenges highlighted during application design including C ++ QT were used to build the user interface, the contour-active method was used to divide and separate image objects from the back-ground, while the clever edge edge method was used to improve the outline ap-pearance of objects. Both methods are implemented on the Android platform and utilize smartphone cameras as an identification tool. This application makes it possible to provide many benefits and great benefits for farm farmers but on the other hand will create technological gaps

Abstract A U-shapedsiphon was used to connect two 600 mL disposed of mineral water-plastic bottles called container A and B. Container A served as a decomposer drum for mixingSargassum porridge, EM4 (effective microorganisms 4), organic nutrients, and water to allow an anaerobic fermentation to occur within 25 days.B was an aeration drum containing an acceptable volume of freshwater. Between these two containers, the siphon was set to bridge the air between containers above the suspension. There were 14 different configurations including a siphon with three different diameters (0.5, 1, 1.5 cm), four different lengths (16, 18, 20, 22 cm), and three different connections (connected to aeration drum, opened to air, closed). The last two configurations did not need the siphon. During the fermentation process, gas and heat were perceptibly released inone way-flowing from A to B and creating bubblesin Bleading to a maintained condition of the fermentation. As the one of main challenging aspects in the production of sargassum liquid fertilizer (SFL) is the considerable number of heavy metals, therefore, we measured some transition metals levels extracted in the filtrate post-25 days to estimate the safety level of the product compared to those mentioned in the Regulation of the Indonesian Ministry of Agriculture (Permentan70/SR/140/10/2011). All data excluding sample S4 were below the limit, except Cd level, whereby two configurations gave the least values of potentially toxic elements, which might be linked to the role of the siphon in giving a favourable condition for preventing the release of the heavy metals trapped in the cell walls.

Background and Objective: This study aims to improve the capacity and level of service at the sixth circle in Jordan by using traffic signals and a roundabout metering approach. Methods: VISSIM software and C++ program were used to improve the capacity and level of service. The site area (Sixth circle) was located near Crown Plaza and the Jordan Gate Towers project, which causes congestion due to heavy traffic flow. Therefore, this paper assesses the traffic in the sixth circle and presents the possible solutions to reduce the daily traffic flow for the users of this circle. Results: Four signals were placed at the roundabout in the second scenario, which was connected to each other with different cycle lengths. 90-second cycle length gives D value of the level of service. The third scenario was placed adaptive signals on the roundabout, which connects traffic signals with ground detectors placed at a certain distance before the signal and based on the queue length of the flow cars that pass the detector. Conclusion: The adaptive signals worked on the opening and closing and were designed according to the language simulation and the adoption of the language C++. The first two signals were opened considering the Swefieh road with the reference of King Faisal for a period of 45 seconds. It was then closed for 45 seconds to open the signal from the next street from the fifth circle with Zahran street.

My article argues that this innovative public screening establishes a mode of communication that connects audiences with the neighbourhood where people gather together and form local communities by sharing experience and emotion based on history, story and memory. This process evokes a source of affective energy that is capable of catalysing social change. It challenges not only previous theoretical approaches to the public sphere, but also the stereotypical understanding of ‘the public’ in the Hong Kong context.

AbstractThe attitudes of the elite of the Grand Duchy of Lithuania and especially of representatives of Radziwill family (Krzysztof and Janusz) towards the election of the last two Vasas are an interesting problem for deliberations and research, especially taking into account differences in the country’s internal and foreign situation in 1632 and 1648, which determined the activities of mentioned above. This article was mainly intended to discuss the problem connected with the attitudes of the Lithuanian nobility towards the election of a new king and also indicating the role of connections of Wladyslaw IV and Jan Kazimierz with the Jagiellonians in political games. Answering the question of what and how influenced the attitudes and moods among the nobility, their argumentation to support one or other candidate requires many years of research and use of methods developed by other humanities, such as sociology, social psychology or political science.
