Using A Cutting The Cake Peer Assessment Method In A Leadership In Information Networking and Telecommunications Course

To satisfy the increasing demands of various group-based dynamic studies, we have developed a variant classroom assessment technique that synthesizes different grading systems, such as a criterion-referenced system, norm-referenced system, peer grading and their modification. This paper describes the Cut-the-Cake Grading Method through introduction of our implementation and its comparison with other assessment methods

Nonlinear dissipation induced photon blockade

We theoretically propose a scheme for photon blockade in a cavity quantum electrodynamical system consisting of an N-type atomic medium interacting with a single-mode Fabry-Perot cavity. In contrast to inefficient nonlinear-dispersion-induced photon blockade suppressed by a large detuning, the photon blockade in our scheme is induced by a large nonlinear dissipation of the cavity created by the N-type atomic system. A deep photon blockade is manifested with a vanishing equal-time second-order correlation function within the cavity linewidth. This work provides an efficient photon blockade because it work in the near-resonance case

Real Risks In A Virtualized World: How Virtualization Is Changing The Way We Manage, Assess, and Mitigate Risk

A dramatic shift has stated to take place in the last decade that is having a pronounced impact on how organizations view information security. Large datacenters and small sensor rooms alike are being impacted by the development and growth of virtualization and the many benefits it provides. This essay will examine how hardware virtualization has changed the landscape of datacenter risk management and how organizations must adapt their security posture to those changes. As mainstream hypenisors like VMware ESXi, Citrix XenServer, and Microsoft Hyper-V become more affordable and easier to implement, their use in providing low-cost, high-utilization solutions is steadily becoming an industry standard, even for smaller shops. Organizations must understand how to assess, manage, and mitigate new types of risk unique to virtualization. By examining the technology behind virtualization, the risks associated with it, and the methods organizations can mitigate and minimize those risks, we will see that virtualization, when implemented properly, can provide a secure, highly beneficial technology on which datacenters can be built

Estimating Causal Effects using a Multi-task Deep Ensemble

A number of methods have been proposed for causal effect estimation, yet few have demonstrated efficacy in handling data with complex structures, such as images. To fill this gap, we propose Causal Multi-task Deep Ensemble (CMDE), a novel framework that learns both shared and group-specific information from the study population. We provide proofs demonstrating equivalency of CDME to a multi-task Gaussian process (GP) with a coregionalization kernel a priori. Compared to multi-task GP, CMDE efficiently handles high-dimensional and multi-modal covariates and provides pointwise uncertainty estimates of causal effects. We evaluate our method across various types of datasets and tasks and find that CMDE outperforms state-of-the-art methods on a majority of these tasks.Comment: 18 pages, 7 figures, 3 tables, published at the 40th International Conference on Machine Learning (ICML 2023

Quantitative characterization of micropore structure for organic-rich Lower Silurian shale in the Upper Yangtze Platform, South China: Implications for shale gas adsorption capacity

 The pores in shales are mainly of nanometer-scale, and their pore size distribution is very important for shale gas storage and adsorption capacity, especially micropores having widths less than 2 nm, which contribute to the main occurrence space for gas adsorption. This study is focused on the organic-rich Lower Silurian black shale from four wells in the Upper Yangtze Platform, and their total organic carbon (TOC), mineralogical composition and micropore characterization were investigated. Low pressure CO2 adsorption measurement was conducted at 273.15 K in the relative pressure range of 0.0001-0.03, and the micropore structure was characterized by Dubinin-Radushkevich equation and density functional theory method and then the relationship between micropore structure and shale gas adsorption capacity was discussed. The results indicated that (1) The Lower Silurian shale have high TOC content in the range of 0.92%-4.96%, high quartz content in the range of 30.6%-69.5%, and high clays content in the range of 24.1%-51.2%. The TOC content shows a strong positive relationship with the quartz content which suggests that the quartz is mainly biogenic in origin. (2) The micropore volume varies from 0.12 to 0.44 cm3 /100g and micropore surface area varies from 4.97 to 17.94 m2 /g. Both of them increase with increasing TOC content, indicating TOC is the key factor to control the micropore structure of the Lower Silurian shale. (3) Low pressure CO2 adsorption measurement provides the most suitable detection range (0.3-1.5 nm) and has high reliability and accuracy for micropore structure characterization. (4) The TOC content is the key factor to control gas adsorption capacity of the Lower Silurian shale in the Upper Yangtze Platform.Cited as: Chen, L., Jiang, Z., Liu, K., et al.

Perovskite light-emitting diodes toward commercial full-colour displays: progress and key technical obstacles

Metal-halide perovskite light-emitting diodes (PeLEDs) possess wide colour gamut, high luminescence efficiency, and low-cost synthesis, making them a promising photonic source for next-generation display applications. Since the first room-temperature emission PeLED was demonstrated in 2014, their performance has improved rapidly within a few years, leading to considerable attention from academia and industry. In this review, we discuss the primary technical bottlenecks of PeLEDs for commercial display applications, including large-area PeLED preparation, patterning strategies, and flexible PeLED devices. We review the technical approaches for achieving these targets and highlight the current challenges while providing an outlook for these perovskite materials and PeLED devices to meet the requirements of the next-generation high-colour-purity full-colour display market
