description: In a 1991 paper, R. Mercer asserted that a Cartan bimodule isomorphism between Cartan bimodule algebras A_1 and A_2 extends uniquely to a normal *-isomorphism of the von Neumann algebras generated by A_1 and A_2 [13, Corollary 4.3]. Mercer's argument relied upon the Spectral Theorem for Bimodules of Muhly, Saito and Solel [15, Theorem 2.5]. Unfortunately, the arguments in the literature supporting [15, Theorem 2.5] contain gaps, and hence Mercer's proof is incomplete. In this paper, we use the outline in [16, Remark 2.17] to give a proof of Mercer's Theorem under the additional hypothesis that the given Cartan bimodule isomorphism is weak-* continuous. Unlike the arguments contained in [13, 15], we avoid the use of the Feldman-Moore machinery from [8]; as a consequence, our proof does not require the von Neumann algebras generated by the algebras A_i to have separable preduals. This point of view also yields some insights on the von Neumann subalgebras of a Cartan pair (M,D), for instance, a strengthening of a result of Aoi [1]. We also examine the relationship between various topologies on a von Neumann algebra M with a Cartan MASA D. This provides the necessary tools to parametrize the family of Bures-closed bimodules over a Cartan MASA in terms of projections in a certain abelian von Neumann algebra; this result may be viewed as a weaker form of the Spectral Theorem for Bimodules, and is a key ingredient in the proof of our version of Mercer's theorem. Our results lead to a notion of spectral synthesis for weak-* closed bimodules appropriate to our context, and we show that any von Neumann subalgebra of M which contains D is synthetic. We observe that a result of Sinclair and Smith shows that any Cartan MASA in a von Neumann algebra is norming in the sense of Pop, Sinclair and Smith.

description: Severe acute respiratory syndrome-coronavirus2 (SARS-CoV2), a new coronavirus has emerged in Wuhan city of China, December 2019 causing pneumonia named Coronavirus disease-19 (COVID-19), which has spread to the entire world. By January 2021, number of confirmed cumulative cases crossed ∼104 million worldwide. Till date, no effective treatment or drug is available for this virus. Availability of X-ray structures of SARS-CoV2 main protease (Mpro) provides the potential opportunity for structure-based drug designing. Here, we have made an attempt to do computational drug design by targeting main protease of SARS-CoV2. High-throughput virtual screening of million molecules and natural compounds databases were performed followed by docking. After that, the protein-ligand complexes were optimized and rescoring of binding energies were accomplished through molecular dynamics simulation and Molecular mechanics Poisson Boltzmann surface area approaches, respectively. In addition, conformational effect of various ligands on protein was also examined through essential dynamics simulation. Three compounds namely ZINC14732869, ZINC19774413, and ZINC19774479 were finally filtered that displayed better binding affinities than N3 (known) inhibitor and formed conformationally stable complexes. Hence, the current study features the potential novel inhibitors against main protease of SARS-CoV2 which might provide an effective therapeutic strategy against COVID-19.

Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: Due to the covid-19 pandemic situation, classes are offered either online or hybrid at Mason Korea campus, and even though synchronous zoom and blackboard Collaborate are actively serving, students have limited chances to communicate or socialize with classmates and instructors. To overcome this limitation, presenters decided to include the KakaoTalk messenger application, the most popular and common communication tool among Korean on mobile phones, lap-tops and desk-tops, for class tools for live communication in and out of the class. KakaoTalk is a free messenger service that most Korean mobile phone holders use every day, and it is also available to international users for free. K-12 teachers as well as university professors are recommended to use this messenger to actively communicate with their classes particularly in the period of pandemic in Korea. Instructors organize group channels for their classes, in which students and instructors can immediately exchange and share text messages, phone calls, video conferences, and quick surveys as well as documents, images, audio, and video files replacing classic functions of the ‘discussion board,’ ‘individual/group emails,’ and uploading feedback on the blackboard. This application helps instructors and students to communicate all around the clock as it is comparatively simpler than logging in to the university account and getting into the blackboard system for communication Reviewing users’ survey data, testimonials and comments on the functions and activities of this tool for the class community, participants will find ideas how this tool can support class communication and exchange of information among the class community members, through which they can invent ways to build up strong sense of community and belonging to each other. Presenters suggest that the university IT team provide an application with which each registered class members can immediately exchange conversation around the clock. Key take-aways: Through review of how this messenger application is used for different areas of the academic discipline, English for Academic Purpose, Chinese language, and Conflict Resolution, participants will be able to notice the real-time communication functions that this application offers and will formulate ideas how they can utilize this type of application for their class communities. In addition, the university IT team will be motivated to add a mobile application that could be linked directly to the registered class communities.

ON DEMAND: Using “Carrots and Sticks” to Promote Student Collaboration and Enhance the Team Experience
Creators: name: Viccora, Elaine
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: We know that collaboration deepens learning, produces better outcomes, and results in fewer headaches for students and professors alike. However, students typically view group assignments as a chance to “divide and conquer;” they work independently before coming together to assemble their individual efforts into a patchwork project, often lacking cohesion. Did you know that professors have the ability to foster collaborative learning by using a combination of carrots (team-building activities) and “sticks” (accountability measures)? We teach “Developing Your Professional Skills I and II,” required classes designed to help students advance their teamwork skills through a variety of group assignments. After teaching these courses for four years, we realize the unique power we have as instructors to both encourage and require that students take steps toward collaboration, boosting the team experience. During this video, we will showcase the strategies we’ve used in our classes and provide tips based on our lessons learned. For the “carrots,” we will explain how/when you may want to use team-building activities and offer a menu of suitable activities (e.g., discussion prompts, sharing activities, fun collaborative tasks, games, and shout-outs) that can be used in both the online and face-to-face environments. Regarding the “sticks,” we will share our accountability model and provide examples on how it can be used to expand student interest in creating positive team experiences.

description: Efficient RF power amplifiers used in third generation systems ( like wide-band WCDMA systems ) require linearization in order to reduce adjacent channel inter-modulation distortion, without sacrificing efficiency. This paper presents a new adaptive digital base-band predistortion system based on look-up table (LUT) called the slope-dependent method, and compares it with the direct linear-LUT used by Cavers, by analysing their performance and convergence time when applied to a wide band signal ( like W-CDMA ) input.

description: An electrical and thermal study of submicron GaN permeable base transistors is presented. Carrier transport in the intrinsic finger is studied with a drift-diffusion model, validated against ensemble Monte Carlo simulation. The effects of geometrical scaling are evaluated, in order to optimize the performance of the intrinsic device. Non-isothermal analysis of the complete multi-finger structure demonstrates that, for optimum performance, the heat sink must be placed on the top of the device.

We prove consistency and asymptotic Gaussianity, in the high-frequency limit, thus generalizing earlier results by Durastanti et al. (2011) based upon standard Fourier analysis on the sphere. The asymptotic results are then illustrated by an extensive Monte Carlo study.

description: A new modeling approach for electron devices up to millimeter-wave frequencies is proposed. It exploits a previously proposed distributed approach with the aim of deriving a more computationally efficient model still preserving good accuracy. In particular, a new electron device model based on a “single active device” and a “distributed description of the parasitic structure” is derived, which can easily be identified through conventional scattering parameter measurements and electromagnetic simulations. Preliminary validation results are provided in the paper.
‘Nice Korea, Naughty Korea’ : media framings of North Korea and the inter-Korean relationship in the London 2012 Olympic Games

description: In this study, I analyze mainstream news-media framings of North Korea and the inter-Korean relationship in the London 2012 Olympic Games. I explore the role that media plays in promoting particular understandings of North and South Korean nations and relationships. My research was guided by the following questions: 1) How did mainstream news-media in South Korea and other national contexts frame the relationship between North Korea and South Korea in the London 2012 Games?; 2) How was North Korea’s involvement in the Games understood and portrayed within different news-media?; 3) To what extent were themes pertaining to the unity of and/or divisions between North and South Korea evident in the coverage?; 4) What differences were there, if any, between the South Korean coverage of these topics and other international news-media coverage?; and 5) What might these differences imply about subjectivity in decision-making processes in mainstream news-media, and/or about how journalists might be implicated in the promotion of stereotypes and/or xenophobia? This study draws on existing research on news-media coverage of conflict, sport, and nationalism with particular attention to the interrelated concepts of ideology, hegemony, and Orientalism (Said, 2003). Live-televised commentary and newspaper articles from South Korea and other English-speaking nations were collected and analyzed using Fairclough’s (1995) Critical Discourse Analysis to examine how language operates in framing events and topics in a manner that may make some points or perspectives more visible than others. The results illustrate that South Korean and international media covered North Korea’s involvement and the inter-Korean relationship during the Games differently. Namely, international media representations of North Korean performance were at times derogatory or dismissive, and included more discussions of the North Korean government and its associated conflicts and issues (as compared to South Korean coverage). As well, emphasis on division was found more often in international coverage when covering the inter-Korean relationship. The study concluded with commentary on the potential role of sport media producers in peace promotion and in the perpetuation of cultural violence, the potential impacts of the studied portrayals on audiences, and possibilities for developing more critically-informed approaches to creating media messages.

description: Direct numerical solution of device transport equations for a transistor, and device modelling approaches based on an equivalent circuit representation, are often seen as essentially competing approaches within non-linear high-frequency CAD. Each method has clear advantages and limitations. This contribution is an attempt to demonstrate the benefits of combining some of the best features of both, using a simplified physical FET model which is highly computable and yet retains key consistencies with the internal semiconductor dynamics in terms of both particle and displacement current. Results are presented which show the high frequency limitations of conventional equivalent circuit model architectures with respect to non-quasistatic behaviour.

description: In the construction of polarization beam-splitters (PBS) and switches a structure can be employed, that is based on the birefringence of periodically laminated dielectric thin films [2,7]. In this work we derive an estimate of the split angle in laminated polarization splitters behaving as negative uniaxial crystals, in the case of oblique incidence. This analysis has been applied to an artificial anisotropic dielectric medium realized by means of layers of a-Si:H and SiO2 [7].

description: Fabrication process and advantages of the new generation quasi-monolithic integration technology are presented. The novel fabrication process gives excellent advantages such as extremely low thermal resistance, and a much lower thermal stress than the earlier QMIT concept [1]. This highly improves the packaging lifetime and electrical characteristics of the active devices. The fabrication process is simple and compatible with fabrication of high-Q passive elements. In comparison to the old concept of QMIT, elimination of air-bridges in this technology not only reduces the parasitics but also enables the fabrication of the rest of the circuit after measuring the microwave characteristics of the embedded active devices. This makes very accurate microwave and millimetrewave designs possible. Using the new fabrication process, microwave and millimetrewave circuits (with both coplanar and microstrip lines) containing power devices have for the first time been realised.

description: Starting in Fall 2020, the Department of Mathematical Sciences initiated a program to expand and build on our Learning Assistant Program (previously only for undergraduate classes) to our core graduate classes as well. This new initiative titled Graduate Learning Assistants (GLAs) consists of a cohort of graduate students that have advanced to PhD candidacy working with graduate students who are taking core courses, to facilitate their learning individually or in small groups. By aiding in active learning within the course and running review sessions for the PhD preliminary exams (both done in a synchronous online format), GLAs promote student discourse and help students develop a deeper understanding of the foundational concepts and connections inherent in the course content they are learning. Since the material of graduate courses is at a very different level from the large undergraduate classes, the method of presentation and interaction is necessarily quite different. In this presentation, the GLAs will explain the pros and cons, what works and what does not, for peer mentoring of graduate students in taking graduate courses and preparing for their PhD prelims. Faculty organizers will also be involved to answer questions about how the program was established and implemented. We hope that this new GLA initiative can serve as a model to enhance and strengthen PhD programs in other disciplines.

Subjects: ING-INF/01 Elettronica

description: A universal DC and pulsed I-V test set is presented, that allows automated DC-only, pulse-only and DC + pulse measurements on 2 and 3 terminal semiconductor devices, the later ones in 3 selectable common-configurations. Tests can be done on packaged devices and on-wafer; temperature dependency studied and time-depended features like trapping effects in GaN-based HEMTs. Novel is that once the overall test setup is assembled, no external hardware changes are neccesary for a full (automated) characterization of all quadrants of the I-V plot, and that in the pulse mode the V and I sampling point already can be at 8 ns from the leading edge, allowing measurements with very limited average device temperature increase.

description: We extend the discontinuous Galerkin (DG) framework to a linear second-order elliptic problem on a compact smooth connected and oriented surface. An interior penalty (IP) method is introduced on a discrete surface and we derive a-priori error estimates by relating the latter to the original surface via the lift introduced in Dziuk (1988). The estimates suggest that the geometric error terms arising from the surface discretisation do not affect the overall convergence rate of the IP method when using linear ansatz functions. This is then verified numerically for a number of test problems. An intricate issue is the approximation of the surface conormal required in the IP formulation, choices of which are investigated numerically. Furthermore, we present a generic implementation of test problems on surfaces.

These protests, in the name of George Floyd and several other African Americans murdered by police across the U.S. in recent years, have drawn further attention to systemic racism in the U.S., which the authors of “This Ain’t Another Statement” point out does not exist only outside the gates of the university or the doors of the classroom. Their demands, along with April-Baker Bell’s (2020) book on linguistic justice for speakers of Black English (BE) and Green and Condon’s (2020) epistolary book chapter subtitled “Anti-Racism and the Teaching of Writing”, demonstrate a new urgency among scholars and educators to promote anti-racist pedagogy, legitimize Englishes of all types, both inside and outside the classroom, and to advocate for multiply marginalized students across the board. With this urgency as a backdrop, a small team of GMU Composition faculty and library scientists will share a video presentation on the anti-racist writing course they developed that centers the multiply-marginalized student and focuses on the promotion of linguistic justice and information literacy in a world of fake news and market-driven algorithms. During the 15-minute video presentation, presenters will walk through the syllabus, focusing on the course’s rationale, pedagogical principles, and major assignments and units. Participants will walk away with one concrete example of what the oft-cited phrase “anti-racist pedagogy” looks like in practice.

description: Background: Childhood maltreatment (CM) is associated with impaired hypothalamic-pituitary-adrenal (HPA) axis negative feedback and cognitive dysfunction, resembling those abnormalities linked to major depressive disorder (MDD). Objectives: We aimed to assess the potential modulating effects of MDD diagnosis or HPA axis function in the association between different types of CM and cognitive performance in adulthood. Methods: Sixty-eight MDD patients and 87 healthy controls were recruited. CM was assessed with the Childhood Trauma Questionnaire. We obtained three latent variables for neuropsychological performance (verbal memory, visual memory and executive function/processing speed) after running a confirmatory factor analysis with cognitive tests applied. Dexamethasone suppression test ratio (DSTR) was performed using dexamethasone 0.25 mg. Results: Different types of CM had different effects on cognition, modulated by MDD diagnosis and HPA axis function. Individuals with physical maltreatment and MDD presented with enhanced cognition in certain domains. The DSTR differentially modulated the association between visual memory and physical neglect or sexual abuse. Conclusions: HPA axis-related neurobiological mechanisms leading to cognitive impairment might differ depending upon the type of CM. Our results suggest a need for early assessment and intervention on cognition and resilience mechanisms in individuals exposed to CM to minimize its deleterious and lasting effects. • We studied the effects of childhood maltreatment (CM), HPA axis feedback (DST), and depression on cognition. • Different types of CM had a distinct impact on cognitive performance. • MDD diagnosis and DST modulated the association between CM and cognition.

description: Let $R$ be a unitary commutative real algebra and $K\subseteq Hom(R,\mathbb{R})$, closed with respect to the product topology. We consider $R$ endowed with the topology $\mathcal{T}_K$, induced by the family of seminorms $ρ_α(a):=|α(a)|$, for $α\in K$ and $a\in R$. In case $K$ is compact, we also consider the topology induced by $\|a\|_K:=\sup_{α\in K}|α(a)|$ for $a\in R$. If $K$ is Zariski dense, then those topologies are Hausdorff. In this paper we prove that the closure of the cone of sums of 2d-powers, $\sum R^{2d}$, with respect to those two topologies is equal to $Psd(K):=\{a\in R:α(a)\geq 0,\textrm{for all}α\in K\}$. In particular, any continuous linear functional $L$ on the polynomial ring $R=\mathbb{R}[X_1,...,X_n]$ with $L(h^{2d})\ge0$ for each $h\in R$ is integration with respect to a positive Borel measure supported on $K$. Finally we give necessary and sufficient conditions to ensure the continuity of a linear functional with respect to those two topologies.

Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: For instructors who traditionally teach in-person, the pandemic has presented new challenges, particularly how to engage students online. The presenters, who are teaching librarians and adjunct faculty members, primarily taught in-person before the pandemic and had to quickly adapt their in-person toolkit to the distance learning environment. Over the past two semesters, they have experimented with different tools and platforms for engagement, including digital whiteboards, which allow students to share ideas, demonstrate understanding, and collaborate with peers. During this session, they will focus on Google Jamboard, a collaborative digital whiteboard which presents an exciting alternative to Zoom or Blackboard Collaborates’ whiteboards. The presenters will detail how they have used Jamboards to facilitate synchronous learning activities such as concept maps, brainstorming sessions, reflections, and more. All participants will receive the Jamboard templates for the activities showcased in the video, which can be easily adapted for any class or presentation. Key Takeaways: 1) Participants will be able to describe Google Jamboard features and tools for student engagement. 2) Participants will be able to identify at least one Jamboard activity or feature to use in their own context.

Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: Mason degree programs have been challenged with honoring COVID-19 safety protocols while also honoring the commitment to student – centered learning that flourishes within inclusive, engaged, and lively classroom discussions. In fall 2021, as part of Mason’s Safe Return to Campus, allowable in-person classroom capacity was at 50% of course enrollment. After a literature review, the Social Work Department chose to expand the synchronous hybrid format (e.g., all students meet on-line, or all meet on-campus) to use HyFlex strategies. In order to address classroom size limitations and to allow for synchronous learning, the department piloted a HyFlex model in which students were divided into two sections. Each week half the class could attend on-campus while the other half attend virtual/on-line; the two sections “switched off’ weekly so that all students could attend (up to half) the weekly classes in person/on-campus. Faculty modified their teaching to address technological challenges such as online audience disengagement, limited microphone range, and audio lag; as well as teaching strategies that allowed for full participation in lectures and in skill-building exercises from a bi-located student attendee. This video presentation will present an overview of the HyFlex strategy, and highlight lessons learned and techniques implemented over Fall 2020 and Spring 2021 semesters. Examples of lessons learned include establishing clear classroom participation norms, utilizing a Zoom assistant to monitor chat, and adjusting physical and online small group activities for the split environment. Participants teaching a synchronous hybrid course will be able to utilize classroom management strategies that maintain student engagement for both audiences. They will apply techniques that address the challenges this format presents. Should Mason Want to explore other modalities for combining on-campus and on-line synchronous sections (for outreach to underserved or distanced students), these techniques could be a guide or beneficial.

Subjects: ING-INF/01 Elettronica

description: This paper describes the development status of the devices based on compound semiconductors especially on gallium arsenide (GaAs) in Japan. In the area of the devices for handy phone, and PCS/PCN application, GaAs MESFETs, HEMTs and HBTs have been actively investigated to have low voltage operation and low power consumption. The market has started to expand and we can see many serious and practical studies in this area. In millimeterwave InP lattice matched HEMTs and GaAs pseudomorphic HEMTs have been developed as active devices for collision avoidance radar, wireless LAN, remote POS system and etc. For high rate optical communication systems, still GaAs MESFET ICs have been developed because the technology is matured today, though HBT ICs are studied for many functions. In the field of data processing, GaAs LSIs have established its position for the highest speed logic in a computer system.
What GaAs market? What will make GaAs win in wireless markets.

description: Over the next five years, analog GaAs semiconductor suppliers participating in emerging wireless applications face critical choices in markets, processes, levels of integration, product categories, packaging, and sales channel match. How will GaAs suppliers win? Historically, GaAs vendors have focused on designs and processes which expand the envelope of performance. Now there are other factors which will be at least as important as maximum performance in determining the GaAs winners when competing against lower material cost technologies such as Silicon.
ON DEMAND: An Example of Authentic Assessment: Building career readiness through online professional networks
Creators: name: Avramovic, Sanja
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: The connection between a student’s education and their future career is a key for many students because their career is often a motivation for and goal of their education. There are several ways to bolster career readiness in online classes. One is through Mason's Career Services Office, which provides tools to guide students through activities to identify and articulate their career-readiness skills. We implemented another step as an alternative/authentic assessment. In the beginning of the semester, all students create their own LinkedIn page, as is suggested by Mason’s Career Service Office. After that, they also should post the link to the discussion board, and classmates would all use this to form mutual contacts. In this way, the class is building connections between a student and the other classmates, instructor, and students who have finished the class in the past. This strategy has shown itself to be easy to implement. At the same time, it is very successful in enabling students to build a strong online community through online professional networks. This strategy also develops a bridge between students and industry. In one example, a previous student shared a job posting from their company asking whether anyone from the class was interested in internships. Previous students have also shared valuable information about jobs, resumes, the skills desired in the field, and the most common mistake that freshly graduated students usually make when applying for a job. In some instances, former students have shared some of the current industry challenges that their companies are facing, which stimulated current students to analyze and contemplate solutions in their class projects. In internal evaluation of one of the courses which employs this strategy, 75% of students indicated that they believe that it will positively impact their career. Seniors are especially interested in this interaction. The interaction has proven motivating for current students and is not restricted to online classes.

description: We present a framework where first principles calculations of jet modification may be carried out in a non-perturbative thermal environment. As an example of this approach, we compute the leading order contribution to the transverse momentum broadening of a high energy (near on-shell) quark in a thermal medium. This involves a factorization of a non-perturbative operator product from the perturbative process of scattering of the quark. An operator product expansion of the non-perturbative operator product is carried out and related via dispersion relations to the expectation of local operators. These local operators are then evaluated in quenched SU(2) lattice gauge theory.

GaAs based optical devices for telecommunications
Creators: name: Carballes, Jean-Claude
Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: ING-INF/01 Elettronica

description: Up to now, for the telecom applications, the optoelectronic components are mainly used in the transmission systems. Due to the higher properties of the optical fiber at 1,3 and 1,55µm wavelengths, InP based adapted components were studied replacing first 0,85µm GaAs based laser diodes. Nevertheless for the short distance transmission links and due to the lower cost, GaAs based laser diodes are always industrially used. Among the different research activities devoted to the telecommunication aspect, two of them are of strong interest for optical amplification and optical interconnection. The recent boom on optical doped fiber amplification and the need of adapted pump laser has recently strongly improved research activities on 0,98µm laser diode. These GaAs based lasers are using "a strained quantum well vertical structure". The laser structure is shortly described. High performances are obtained with a CW optical power = 150mW for only = 200mA. Commercial products are already available but important research activity is still in progress. Finally due to the higher and higher bit rates needed in the telecommunication industry, optical interconnection is becoming an important technology. It allows to simplify the development of the sophisticated equipments. Several channels (> 4), with high bit rates (622 Mb/s ; 2,5 Gb/s) are used in parallel which need the development of adapted laser arrays. GaAs based lasers are studied in several companies and the paper focuses on the new vertical cavity surface emitting laser.
