Bhagavad Gitā & the Art of Leadership: Old Text, New Context!
Get PDFAuthor and scholar Satinder Dhiman focuses upon the pervasive and necessary role of spirituality in values-based leadership. He notes that while the leadership literature is plentiful, the Bhagavad Gītā represents one of the very few writings which explores the core psychological, philosophical, ethical, and spiritual underpinnings of leadership roles. In this article, the author applies hermeneutics to the Gītā to highlight important leadership lessons and to apply such lessons to contemporary organizational leadership. Through selfless work, a true leader eschews an egoistic pursuit of self-aggrandizement to achieve the freedom of serving others. Thus, Dhiman concludes, the Gītā teaches its readers how “to discover the sacred in life while remaining fully engaged in the secular activities.
Security of Hard Disk Encryption
No full textEncryption is the art of preserving confidentiality of digital information. It is considered to be one of the most ideal solutions for providing data confidentiality and safety of computer hard disk. Many disk encryption software are commercially available with a variety of features. But how much effective security is provided by those software is the ultimate question. Encryption algorithms used by those software are vulnerable to known cryptanalysis. Design and implementation weaknesses critically leave backdoors inside those software themselves. Easy and smart methods are used to defeat the software’s security either by manipulating external hardware or by exploiting user unawareness. This thesis evaluates the potential vulnerabilities of commercial hard disk encryption software that are claimed to provide absolute security of hard disk content

Using Machine Learning to Quantify the Robustness of Network Controllability
No full textThis paper presents machine learning based approximations for the minimum number of driver nodes needed for structural controllability of networks under link-based random and targeted attacks. We compare our approximations with existing analytical approximations and show that our machine learning based approximations significantly outperform the existing closed-form analytical approximations in case of both synthetic and real-world networks. Apart from targeted attacks based upon the removal of so-called critical links, we also propose analytical approximations for out-in degree-based attacks.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Network Architectures and Service
Effect of Gamma Radiation on Survival and Fertility of Male Anopheles stephensi Liston, Irradiated as Pharate Adults
Get PDFEffect of radiations on the survival and fertility of male Anopheles stephensi Liston was evaluated in the laboratory with 70 and 100 Gy radiation dose. Irradiation of pharate adults with 100 Gy dose resulted in reduced emergence and longevity as compared to control (0 Gy) and 70 Gy dose. Fecundity and fertility of female An. stephensi mated with male irradiated as pharate adults was determined upto four blood meals. Significant decline was observed in fecundity after each blood meal at 100 Gy as compared to 0 Gy and 70 Gy irradiation. Similarly, the fertility was also decreased after each blood meal at 100 Gy irradiation. The present study indicates the suitability of 100 Gy dose for irradiation of pharate adult stage of mosquito as a part of mosquito management.--------------------------------------------------------------------------------------------------------Defence Research Laboratory, Tezpur, India*Corresponding author, Email: dhiman_81@ indiatimes.com Please Cite This Article As:Kavita Yadav, Sunil Dhiman Indra Baruah and Lokendra Singh. 2010.

Measuring the robustness of network controllability
No full textNetworks are all around us, telecommunication networks, road transportation networks, and the Internet are a few examples of networks that we encounter every day. The entities in a network are represented by nodes and the interconnections between them are represented by links. For example, in a telecommunication network, a node could be an end point for data transmission, a redistribution point or in physical terms, an entity that is capable of receiving, transmitting or redistributing information and a link could be a wired or a wireless connection between the nodes. It is of prime importance that the networks perform their functions properly. To ensure the effective operation of such networks, we need to control them by applying external inputs on some nodes which are known as driver nodes. We say that a network is controllable if it can be driven from any arbitrary state to any desired state in finite time under the control of driver nodes which are attached to the external inputs. Networks are often confronted with perturbations in the form of targeted and random attacks to disrupt their operation. Such perturbations make these networks less controllable. Thus, more driver nodes are needed to gain the full controllability of these networks. As a result, the robustness of network controllability decreases. In this study, the minimum number of driver nodes which gain full controllability after failures or attacks is chosen as the robustness metric.Existing closed-form analytical approximations estimate the normalized minimum number of driver nodes as a function of the fraction of removed links in both targeted and random attacks. However, the approximations sometimes do not fit with the simulations and the errors between the approximations and simulations are large. The main objectives of this study are to improve the analytical approximations using machine learning methods for both targeted and random attacks and additionally, derive a suitable analytical approximation for the out-in degree-based attack. Specifically, we use Linear Regression, Random Forest, and Artificial Neural Networks. To evaluate the performance of our machine learning models, we compare them with analytical approximations and simulations. In addition to this, we also study the attack based variability in estimating the minimum number of driver nodes using robustness envelopes.Based on the performance evaluations, we found that the approximations using machine learning models significantly outperform the existing closed-form analytical approximations for the minimum number of driver nodes, both in real-world and synthetic networks. Furthermore, we also assess the performance of our analytical approximations for the out-in degree-based attacks by comparing them with simulations.Electrical Engineering | Telecommunications and Sensing System
Natural furin inhibitor(s) as potent therapeutic molecule to mitigate SARS-CoV-2 infection
No full textThe COVID 2019 has had been going pandemic as per WHO situation reports. The major differentiating point in this virus is the presence of a unique furin cleavage site. Our insilico study points out to the effectiveness of a potent plant origin furin inhibitor. We exploited the aspect of the cleavage machinery of furin subunits which is critical and indispensible to the entry of SARS-CoV-2 in human cells and subsequent massive contagion. In-silico analysis was done to observe the interactions of proposed analogs of protease inhibitor of plant origin against furin protein as well as the furin spike glycoprotein (SGP) binding machinery. This was done by docking protocols using Hex 6.0 software followed by molecular Dynamic simulation (MDS) analysis in 100 ns scale using Amber94. Further, the images were analysed with PyMol software. The analogs I, II and III included in our study showed strong interactivity against furin individually, as well as the furin-Spike Glycoprotein 1 binding machinery. The findings were confirmed using molecular dynamic simulation analysis which indicated good structural stability and ability to neutralise furin and furin-spike glycoprotein 1. Analog II was found to be the best interactive molecule against furin, showing the least deviation (1.484 ± 0.0064). Also, it was the most effective against furin + Spike glycoprotein I machinery [1.575 ± 0.01]. We report the first of its kind of natural furin inhibitor(s) which would disrupt the furin machinery of SARS-CoV-2 and help in controlling the COVID-19 contagion. Communicated by Ramaswamy H.

Internal Auditing of Organizational Spiritual Identity (OSI)
No full textThe aim of this chapter is to argue that it is possible to identify and audit spiritual (and nonspiritual) signifiers in organizations, and that this process has the potential to reveal an organizational spiritual identity (OSI). A rationale for undertaking the process is developed by highlighting scholarly literature and empirical findings suggesting benefits in applying spiritual principles to workplace practices, thatmay, in turn, help to offset the potential for costly and painful consequences, such as employee conflict, dismissal, or resignations (Crossman 2016). The implications of spiritual "fit," in terms of recruitment and retention, as well as creating spiritually safe organizations, are also discussed. The author acknowledges that the relationship between organizational identity and spirituality, as a line of enquiry, is still in its infancy and calls for further empirical work, perhaps in the form of case studies, exploring the process and outcomes of conducting audits of OSI in organizations. Some suggestions on conducting an OSI audit are also submitted
