Analysis of Phenomenon at Quantum Capacitance Limit of SNWFET using FETToy

In The proposed paper several interesting phenomenon that happens at Quantum Conductance Limit (QCL) like transconductance of One Dimensional-Silicon Nano Wire Field Effect Transistor (1D-SNWFET), mobile electron density and injection velocity is studied and simulated using Fettoy simulation tool. The selected gate material in silicon nanowire field effect transistor is SiO2 with K=3.9 and HFO2 with K=20. A coaxial SNWFET is simulated and the results illustrate the essential physics and peculiarities of 1D nanowire FETs, such as the saturation of channel conductance at full degenerate limit and the saturation of transconductance at the quantum capacitance limit and the full degenerate limit

MSEA: Modified Symmetric Encryption Algorithm

In this article, a new symmetric block cipher named MSEA is proposed. MSEA is based on ARX cryptographic design technique. MSEA is simple in nature due to the use of combinations of elementary operations like modular addition, bit-wise rotation and bit-wise XOR. In MSEA, plain text block, secret key, and number of encryption rounds are variable in size, while the size of cipher text is double of size of plain text. Data-dependant rotation is the most vital feature of MSEA through which the unpredictability of encrypted text is increasing. Key formation and encryption/decryption schemes of MSEA are significantly fast

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

What are Social Information Signals Worth? Evidence from Randomized Field Experiments

In this study, we examine how does social information drive user engagement in e-learning platforms. We model two distinct outcomes related to user engagement: content consumption CC (e.g., watching a video) and content organization CO (e.g., adding a video to a playlist). We examine two types of social information signals, which are distinguished based on the source: peer actions (PA) and expert recommendation (ER). We employ a series of field experiments on a mobile e-learning application to tease out the causal influence of PA and ER information signals on CC and CO. Our results indicate that the two information signals exert uneven influence, driving CC but not CO actions of user. These finding presents an important boundary condition for the influence of social information signals across the user engagement ladder. The study contributes to recent discussion on the potential value and impact of revealing information signals about other users’ behavior in digital platforms

Effect of Status-based Gamification on User Engagement: Evidence from A Randomized Field Experiment

Although a plethora of mobile applications (Online platforms) use game design elements that imbibe a sense of excitement and achievement, there appears to be a research gap addressing the user’s susceptibility to Status Characteristics of the opponent in (dyadic) competitive digital environments. Through the online experiment on a mobile e-learning application, we are seeking to assess whether diffuse (e.g., gender) and specific status characteristics (e.g., competency) of the opponent influence user engagement. This research study aims to contribute to the literature on online gamification, user engagement, and status characteristic theory

Immune System of Fish: An Evolutionary Perspective

Fishes are the most successful and diverse group of vertebrate animals, first appeared during Devonian period. Despite of certain differences, the immune system of fish is physiologically similar to that of higher vertebrates. The heterogenous group of fishes are the apparent link between innate immunity and the first appearance of the adaptive immune response. Importantly, fishes have immune organs homologous to that of mammalian immune system. In comparison to higher vertebrates, fishes live free in their environment from the early embryonic stage and during that time mostly they are dependent on non-specific immune system for their survival. In the fishes, non-specific immunity is the fundamental defense mechanism, therewith acquired immunity also plays key role in maintaining homeostasis by activation though a system of receptors proteins, which identify pathogen associated molecular pattern typical of pathogenic microorganism includes lipopolysaccharides, peptidoglycans, DNA, RNA and other molecules that are typically not present on the surface of multicellular organism. There are several external factors like environmental factors, biological factors, stress and internal factors like genetic makeup, age and sex, maternal effect etc. can affect immunological defense capabilities of the fishes

Breast screening revisited

Breast screening is the medical screening of asymptomatic, apparently healthy women for breast lump in an attempt to achieve an earlier diagnosis. The assumption is that the early detection will improve outcomes. In western countries, breast screening programs have led to a significant reduction in mortality and improved prognosis of patients with breast cancer. However in India, although the number of breast cancer are on the rise there is no such organized program. This article emphasizes on the importance of breast screening and protocol to be followed in our country where it can have significant impact on the prognosis
