Global Stablecoins And China’S Cbdc: New Moneys With New Impacts On The Financial System?, Wei Shen, Heng Wang

Research Collection Yong Pung How School Of Law

Digital currencies are reshaping the financial, monetary, and regulatory landscape. There are at least two routes for the development of digital currencies. One is global stablecoins (e.g., Diem that is previously named Libra), issued by private players, while the other is central bank digital currency (CBDC) issued by central banks, with China’s CBDC as an example and possibly the first CBDC that will be issued by a major economy. Albeit in their rudimentary stages, global stablecoins and China’s CBDC are likely to disrupt the current financial system and challenge existing financial regulation. This article examines two crucial but under-explored questions: …

Multi-Polarization Phase Retrieval In Near Field Far-Field Transformation, Yuan Ping, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

In near field far-field transformation (NFFFT), accurate recovery of the current distribution is subjected to the phase measurement. Phase retrieval is an alternative way to recover the current distribution by utilizing the magnitude-only near field sampling data. In phase retrieval algorithm, sufficient independent measurement data are required. Multi-polarization algorithm is employed to generate different current distribution, then, obtaining more independent near field data. Experimental validations of a numeric examples show its potentialities and interest.

Partial Arc Sampling Receiving Scheme For Demultiplexing Of Orbital Angular Momentum Vortex Beam, Yanming Zhang, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Due to the divergence of the orbital angular momentum (OAM) beam, the OAM demultiplexing needs a considerable aperture size to acquire the OAM field information, which brings the challenges to implementation of the receiving end. To tackle this issue, we develop a partial arc sampling receiving (PASR) scheme for demultiplexing of the vortex beams by using the augmented dynamic mode decomposition (A-DMD) approach. Simulation benchmarks are provided to demonstrate the validity of the proposed novel demultiplexing method.

Model Computation With Second-Order Radiative Transfer Equation For Snow Medium Using Coupled Finite Element Method And Method Of Moment And Relaxed Hierarchical Equivalent Source Algorithm, Hamsalekha A. Kumaresan, H. T. Ewe, Gobi Vetharatnam, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Active microwave remote sensing is essential to monitor the conditions of the environment by analyzing the microwave returns from the earth terrain. Various Computational Electromagnetics (CEM) techniques are implemented to study the backscattering coefficient of numerous earth terrains such as vegetation and snow medium. In this paper, a theoretical model based on second order radiative transfer equation is investigated by incorporating two computational methods which are known as coupled Finite Element Method (FEM) and Method of Moment (MoM), and Relaxed Hierarchical Equivalent Source Algorithm (RHESA). These theoretical models consider three shapes of scatterers which can be used to represent the …

Spandeck: A Relational View Of The Duty Of Care, Kian Peng Soh

Research Collection Yong Pung How School Of Law

The use of a general framework in the determination of a duty of care has seemingly fallen out of favour following the UK Supreme Court’s decision in Robinson. Relying on the example of the Spandeck framework in Singaporean jurisprudence, this piece presents the argument that such frameworks, being consistent with a relational conception of tort law, can provide a useful means of determining whether a duty of care exists. In so doing, this piece addresses some criticisms of the relational view and re-emphasises the important role the duty of care plays in the tort of negligence.

Hybrid Beamforming With Deep Learning For Large-Scale Antenna Arrays, Rentao Hu, Lijun Jiang, Ping Li

Electrical and Computer Engineering Faculty Research & Creative Works

The emergence of highly directional beamforming technology makes millimeter wave frequency band communication possible in future wireless communication networks. Based on the multipath characteristics of millimeter wave frequency communication, a high-precision multipath channel estimation algorithm based on signal subspace is proposed. In the mobile terminal, an iterative heuristic radiofrequency combination algorithm based on spatial points is proposed. The analog precoding at the base station uses deep learning to accelerate the calculation, and then the multi-user communication is modeled to design the digital precoding. The simulation results show that the multi-channel estimation algorithm can estimate 4 paths with an error of …

Evolution Of International Investment Agreements In Africa: Features And Challenges Of Investment Law “Africanization”, Makane Moïse Mbengue, Stefanie Schacherer

Research Collection Yong Pung How School Of Law

African States, African Regional Economic Communities (RECs), and the African Union have adopted a number of new investment instruments in recent years. Many of these instruments are highly innovative and mark a clear departure from old European-styled IIAs. The Africanization of international investment law or, in other words, the prise en main of African States and organizations to design the regulation of international investment according to their policy and development priorities has become an evident contemporary phenomenon. At the same time, the most innovative approaches can be found in intra-African IIAs, i.e., in IIAs concluded between two or more African …

The Uncanny Swipe Drive: The Return Of A Racist Mode Of Algorithmic Thought On Dating Apps, Gregory Narr

Publications and Research

As algorithmic media amplify longstanding social oppression, they also seek to colonize every last bit of sociality where that oppression could be resisted. Swipe apps constitute prototypical examples of this dynamic. By employing protocols that foster absent-minded engagement, they allow unconscious racial preferences to be expressed without troubling users’ perceptions of themselves as non-racist. These preferences are then measured by recommender systems that treat “attractiveness” as a zero-sum game, allocate affective flows according to the winners and losers of those games, and ultimately amplify the salience of race as a factor of success for finding intimacy. In thus priming users …

They highlight the challenges and issues that have regrettably, but understandably, limited information sharing, as well as some best practices that have emerged. They also report on local activities and details for which there is not yet a consensus. This journal issue is not the first word on the subject; we …

Sonic Femininity: The Ronettes' Transgressive Gender Performance, Hilarie Ashton

Publications and Research

Iconic sixties girl group the Ronettes are frequently (and justly) celebrated for anchoring the Wall of Sound and inspiring the Beatles, but in their own right, they transgressed social, gendered expectations in revolutionary ways. Framed by a notion I call the sonic feminine, a recuperative theoretical space for the revolutionarily transgressive work of female and femme artists, I argue that the Ronettes, and lead singer Ronnie Spector in particular, enacted a kind of cultural rebellion: they crafted their images to made-up heights that tease the boundaries of drag across the spaces of the stage, the recording studio, the bathroom, and …

O Espaço E O Tempo Do Valor, David Harvey, Artur Renzo

Publications and Research

O artigo discute a lei do valor em Karl Marx como valor em movimento, que se faz valer no espaço e no tempo. Entende-se que o movimento não pode ocorrer no vácuo, sendo necessário abandonar a visão do valor que se move sem estar ancorado em nenhum lugar e passar a enxergá-lo criando geografias de cidades e redes de transportes; formando paisagens agrícolas para a produção de alimentos e matérias-primas; englobando fluxos de pessoas, bens e informações; determinando configurações territoriais de valores fundiários e habilidades de trabalho; organizando espaços de trabalho, estruturas de governo e administração. Conclui-se que há três …

Exclusion Statistics For Particles With A Discrete Spectrum, Stéphane Ouvry, Alexios P. Polychronakos

Publications and Research

We formulate and study the microscopic statistical mechanics of systems of particles with exclusion statistics in a discrete one-body spectrum. The statistical mechanics of these systems can be expressed in terms of effective single-level grand partition functions obeying a generalization of the standard thermodynamic exclusion statistics equation of state. We derive explicit expressions for the thermodynamic potential in terms of microscopic cluster coefficients and show that the mean occupation numbers of levels satisfy a nesting relation involving a number of adjacent levels determined by the exclusion parameter. We apply the formalism to the harmonic Calogero model and point out a …

The ‘Global South’ In The Study Of World Politics: Examining A Meta Category, Sebastian Haug, Jacqueline Braveboy-Wagner, Günther Maihold

Publications and Research

This introductory contribution examines the ‘Global South’ as a meta category in the study of world politics. Against the backdrop of a steep rise in references to the ‘Global South’ across academic publications, we ask whether and how the North–South binary in general, and the ‘(Global) South’ in particular, can be put to use analytically. Building on meta categories as tools for the classification of global space, we discuss the increasing prominence of the ‘Global South’ and then outline different understandings attached to it, notably socio-economic marginality, multilateral alliance-building and resistance against global hegemonic power. Following an overview of individual …

Wavefront-Selective Fano Resonant Metasurface, Adam C. Overvig, Andrea Alù

Publications and Research

Fano resonances are conventionally understood as sharp spectral features with selectivity in the momentum-frequency domain, implying that they can be excited only by plane waves with specific frequencies and incident angles. We demonstrate that Fano resonances can be made generally selective in the space-frequency domain. They can be tailored to resonate only when excited by a frequency, polarization, and wavefront of choice. This generalization reveals that Fano systems are characterized by eigenwaves that scatter to their time-reversed image upon reflection. Although in conventional Fano systems this trivially occurs for normally incident plane waves, we show that, in general, the selected …

The Association Of Pregnancy Control, Emotions, And Beliefs With Pregnancy Desires, Meredith G. Manze, Diana R. Romero, Prabal De, Josette Hartnett, Lynn Roberts

Publications and Research

Context

Standard pregnancy intentions measures do not always align with how people approach pregnancy. Studies that have investigated beyond a binary framework found that those with “ambivalent” feelings towards pregnancy are less likely to use contraception consistently, but the reasons for this are unclear. We sought to gain a nuanced understanding of pregnancy desires, and how perceptions about pregnancy are associated with contraceptive use.

Methods

We used non-probability quota sampling based on sex, age, and geographic region for a web-based survey of heterosexual men and women, aged 21–44 years, who could become pregnant/impregnate and were not currently pregnant (n = …

Human Retinal Organoids Release Extracellular Vesicles That Regulate Gene Expression In Target Human Retinal Progenitor Cells, Jing Zhou, Miguel Flores‑Bellver, Jianbo Pan, Alberto Benito‑Martin, Cui Shi, Onyekwere Onwumere, Jason Mighty, Jiang Qian, Xiufeng Zhong, Tasmim Hogue, Baffour Amponsah‑Antwi, Linda Einbond, Rajendra Gharbaran, Hao Wu, Bo‑Juen Chen, Zhiliang Zheng, Tatyana Tchaikovskaya, Xusheng Zhang, Hector Peinado, Maria Valeria Canto‑Soler, Stephen Redenti

Publications and Research

The mechanisms underlying retinal development have not been completely elucidated. Extracellular vesicles (EVs) are novel essential mediators of cell‑to‑cell communication with emerging roles in developmental processes. Nevertheless, the identification of EVs in human retinal tissue, characterization of their cargo, and analysis of their potential role in retina development has not been accomplished. Three‑dimensional retinal tissue derived from human induced pluripotent stem cells (hiPSC) provide an ideal developmental system to achieve this goal. Here we report that hiPSC‑derived retinal organoids release exosomes and microvesicles with small noncoding RNA cargo. EV miRNA cargo‑predicted targetome correlates with Gene Ontology (GO) pathways involved in …

Framing Inclusion: The Media Treatment Of Irregular Immigrants' Right To Health Care In Spain, Alisa Petroff, Anahí Viladrich, Sònia Parella

Publications and Research

With the passing of Royal Decree-Law 16/2012, Spain’s national health system switched from a model defined by universal and free health care principles, to a private insurance system that excluded large population groups. Based on a qualitative research design, this paper examines the media treatment of undocumented immigrants’ prerogatives to public health care in Spain (2012–2018). The analysis of 234 articles, drawn from three major Spanish newspapers, reveals three frames that underscore the media’s "rhetorics of inclusion," which argue for the extension of free medical services to irregular immigrants a topic traditionally underestimated by the literature. The moralist frame, supported …

Public Debt, Its Impact On Gdp & Crowding Out Effect: Evidence From The Usa, Swapnil Landge

Publications and Research

In this study, we examined the long-term relationship between public debt, GDP, private investment, and interest rates. We found two significant long-term relationships among these variables. First, interest rates are positively correlated with public debt and negatively correlated with GDP. Second, private investment is negatively correlated with public debt and positively correlated with GDP. These findings suggest the presence of a crowding out effect, where public debt limits private investment by increasing interest rates and reducing access to available funds.

Can Investment Shocks Helps To Explain The Us Business Cycles?, Swapnil Landge

Publications and Research

In this paper, I developed a standard neoclassical growth model to understand the importance of investment shock on business cycle fluctuation. In addition to investment shock, my model includes technology shock too. Using the Simulation-based PEA (Parameterized expectations algorithm) approach, i estimate the Model. The model provides evidence that investment shocks constitute a significant force behind U.S. business cycles. Model in this paper reaffirms the comovement of consumption and investment with output and accurately predicts the Investment to output,capital to output ratio and the labour for the US economy.

We developed a learning activity for medical students to teach and discuss just culture as part of a patient safety curriculum.

METHODS: This small-group, discussion-based learning activity was aimed at third-year medical students. Over 5 years, 628 students participated in it. The session had three components: a presession case-based survey, a didactic lecture, and a facilitated small-group discussion. Participants evaluated the session using our institution's …

The Interface And Instrumentality Of Eurorack Modular Synthesis, Eliot Bates

Publications and Research

In this essay, I will examine a couple of aspects of hardware modular synthesizers which, despite not being a “new” morphological form (most commercially sold synthesizers from the 1960s through the early 1970s were modular), experienced an extremely unlikely expansion of interest and activity in the mid-1990s. With a contemporary modular synth, users buy a powered rack that holds modules specific to one of several competing formats. For the two most widely adopted formats, Eurorack (sometimes called 3U in reference to the height of modules, or Doepfer A-100 after the first branded system to adopt this panel height) and MOTM/MU …
