Survey On Quantum Circuit Compilation For Noisy Intermediate-Scale Quantum Computers: Artificial Intelligence To Heuristics, Janusz Kusyk, Samah Mohamed Saeed, Muharrem Umit Uyar

Publications and Research

Computationally expensive applications, including machine learning, chemical simulations, and financial modeling, are promising candidates for noisy intermediate scale quantum (NISQ) computers. In these problems, one important challenge is mapping a quantum circuit onto NISQ hardware while satisfying physical constraints of an underlying quantum architecture. Quantum circuit compilation (QCC) aims to generate feasible mappings such that a quantum circuit can be executed in a given hardware platform with acceptable confidence in outcomes. Physical constraints of a NISQ computer change frequently, requiring QCC process to be repeated often. When a circuit cannot directly be executed on a quantum hardware due to its …

Alternative View Of Oxygen Reduction On Porous Carbon Electrocatalysts: The Substance Of Complex Oxygen-Surface Interactions, Giacomo De Falco, Marc Florent, Jacek Jagiello, Yongqiang Cheng, Luke L. Daemen, Anibal J. Ramirez-Cuesta, Teresa J. Bandosz

Publications and Research

Electrochemical oxygen reduction reaction (ORR) is an important energy-related process requiring alternative catalysts to expensive platinum-based ones. Although recently some advancements in carbon catalysts have been reported, there is still a lack of understanding which surface features might enhance their efficiency for ORR. Through a detailed study of oxygen adsorption on carbon molecular sieves and using inelastic neutron scattering, we demonstrated here that the extent of oxygen adsorption/interactions with surface is an important parameter affecting ORR. It was found that both the strength of O2 physical adsorption in small pores and its specific interactions with surface ether functionalities in the …

Value Distribution And Markets For Social Justice In Global Value Chains: Interdependence Relationships And Government Policy, Lilac Nachum

Publications and Research

Global value chains are highly prone to distortions in value distribution among participants. Their global fragmentation and relational governance undermine the effectiveness of regulatory intervention in amending these distortions. In this paper, I propose a new mechanism to administer value distribution that is in tune with the nature of these production systems. Building on interdependence theory, I suggest that interdependencies inherent in the co-specialized nature of supply chains give participants the power to alter the trade-offs between investment in social causes and economic gains and to incentivize socially desired behavior. I show how the interdependence logic manifests at varying levels …

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

Advanced Science Research Center

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 …

Gap Junction-Mediated Glycinergic Inhibition Ensures Precise Temporal Patterning In Vocal Behavior, Boris P. Chagnaud, Jonathan T. Perelmuter, Paul M. Forlano, Andrew H. Bass

Publications and Research

Precise neuronal firing is especially important for behaviors highly dependent on the correct sequencing and timing of muscle activity patterns, such as acoustic signaling. Acoustic signaling is an important communication modality for vertebrates, including many teleost fishes. Toadfishes are well known to exhibit high temporal fidelity in synchronous motoneuron firing within a hindbrain network directly determining the temporal structure of natural calls. Here, we investigated how these motoneurons maintain synchronous activation. We show that pronounced temporal precision in population-level motoneuronal firing depends on gap junction-mediated, glycinergic inhibition that generates a period of reduced probability of motoneuron activation. Super-resolution microscopy confirms …

On The Future Of Ijsl: Trans-Collaboration And How To Overcome The Structural Constraints On Knowledge Production, Distribution And Dissemination, José Del Valle

Publications and Research

In this essay, using as a point of departure his dilemma to accept or not the invitation to be a member of IJSL’s Editorial Board, del Valle discusses the limitations that academic publishing places on scholars in the humanities and interpretive social sciences: their choice of objects and analytical protocols, and the modes of distribution and dissemination of their production. The constraints imposed by highly bureaucratized universities and publishing companies are set against the intellectual imperative to build academic fields grounded in equality and inclusion. The essay concludes with some thinly drawn goals towards more dynamic trans-collaborative forms of knowledge …

Does Rehearsal Matter? Left Anterior Temporal Alpha And Theta Band Changes Correlate With The Beneficial Effects Of Rehearsal On Working Memory, Chelsea Reichert Plaska, Kenneth Ng, Timothy M. Ellmore

Publications and Research

Rehearsal during working memory (WM) maintenance is assumed to facilitate retrieval. Less is known about how rehearsal modulates WM delay activity. In the present study, 44 participants completed a Sternberg Task with either intact novel scenes or phase-scrambled scenes, which had similar color and spatial frequency but lacked semantic content. During the rehearsal condition participants generated a descriptive label during encoding and covertly rehearsed during the delay period. During the suppression condition participants did not generate a label during encoding and suppressed (repeated “the”) during the delay period. This was easy in the former (novel scenes) but more difficult in …

Predicting Vasovagal Responses: A Model-Based And Machine Learning Approach, Theodore Raphan, Sergei B. Yakushi

Publications and Research

Vasovagal syncope (VVS) or neurogenically induced fainting has resulted in falls, fractures, and death. Methods to deal with VVS are to use implanted pacemakers or beta blockers. These are often ineffective because the underlying changes in the cardiovascular system that lead to the syncope are incompletely understood and diagnosis of frequent occurrences of VVS is still based on history and a tilt test, in which subjects are passively tilted from a supine position to 20◦ from the spatial vertical (to a 70◦ position) on the tilt table and maintained in that orientation for 10–15 min. Recently, is has been shown …

Using Carrots Not Sticks To Cultivate A Culture Of Safeguarding In Sport, Judith L. Komaki, Yetsa A. Tuakli-Wosornu

Publications and Research

The power-driven, win-at-all-costs milieu of many sport settings can create fertile ground for athlete victimization and abuse (Roberts et al., 2020). Victory can in fact be so sovereign that abusive coaches and staff are enabled and “even rewarded. . . in the name of winning” (Armour, 2020). Athlete abuse prevention therefore requires systemic cultural change (Letourneau et al., 2014; Rhind and Owusu-Sekyere, 2017). Thus far, however, enacting this idea has eluded organizations in sport (Mountjoy et al., 2016; Harris and Terry, 2019; Kerr et al., 2019; Rhind and Owusu-Sekyere, 2020) as well as in other settings (National Academies of Sciences, …

General Biology 2 Laboratory Manual, Dmitry Y. Brogun, Azure N. Faucette, Kristin Polizzotto, Farshad Tamari

Open Educational Resources

Currently, many academic institutions are using one or more variations of online modalities due to the Covid-19 pandemic, and science educators face a unique challenge with distance-learning laboratories. Many resources to engage students in virtual, interactive laboratory activities exist, but we found that high costs and/or overlooked content left gaps for several topics typically taught in a general, introductory biology course for undergraduate biology majors (e.g., organismal biology). Additionally, resources for an online lab must be identified and curated from multiple sources, requiring intense demands on the instructors’ time. To meet this need and to overcome the financial burden of …

Is “Just Googling It” Good Enough For First-Year Students?, Maureen Richards

Publications and Research

This study analyzes citations by first-year students to determine what content they were citing and whether it was available through the open web or the library. Examining the role of these two places as content providers for academic work fills a gap in the literature. Most of the cited works were available through the library and the open web. As the line between content providers continues to blur, these results can help academic libraries prioritize what to teach students about information literacy, where to focus collection development efforts and how to promote the discovery of library resources.

Diurnal Cycle Of Passive Microwave Brightness Temperatures Over Land At A Global Scale, Zahra Sharifnezhad, Hamid Norouzi, Satya Prakash, Reginald Blake, Reze Khanbilvard

Publications and Research

Satellite-borne passive microwave radiometers provide brightness temperature (TB) measurements in a large spectral range which includes a number of frequency channels and generally two polarizations: horizontal and vertical. These TBs are widely used to retrieve several atmospheric and surface variables and parameters such as precipitation, soil moisture, water vapor, air temperature profile, and land surface emissivity. Since TBs are measured at different microwave frequencies with various instruments and at various incidence angles, spatial resolutions, and radiometric characteristics, a mere direct integration of them from different microwave sensors would not necessarily provide consistency. However, when appropriately harmonized, they can provide a …

The Neural Correlates Of Cued Reward Omission, Jessica A. Mollick, Luke J. Change, Anjali Krishnan, Thomas E. Hazy, Kai A. Krueger, Guido K. W. Frank, Tor D. Wager, Randall C. O'Reilly

Publications and Research

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in …

A Bisphosphonate With A Low Hydroxyapatite Binding Affinity Prevents Bone Loss In Mice After Ovariectomy And Reverses Rapidly With Treatment Cessation, Abigail A. Coffman, Jelena Basta-Pljakic, Rosa M. Guerra, Frank H. Ebetino, Mark W. Lundy, Robert J. Majeska, Mitchell B. Schaffler

Publications and Research

Bisphosphonates (BPs) are a mainstay of osteoporosis treatment; however, concerns about bone health based on oversuppression of remodeling remain. Long-term bone remodeling suppression adversely affects bone material properties with microdamage accumulation and reduced fracture toughness in animals and increases in matrix mineralization and atypical femur fractures in patients. Although a “drug holiday” from BPs to restore remodeling and improve bone quality seems reasonable, clinical BPs have long functional half-lives because of their high hydroxyapatite (HAP) binding affinities. This places a practical limit on the reversibility and effectiveness of a drug holiday. BPs with low HAP affinity and strong osteoclast inhibition …

T-Moca: A Valid Phone Screen For Cognitive Impairment In Diverse Community Samples, Mindy J. Katz, Cuiling Wang, Caroline O. Nester, Carol A. Derby, Molly E. Zimmerman, Richard B. Lipton, Martin J. Sliwinski, Laura A. Rabin

Publications and Research

Introduction: There is an urgent need to validate telephone versions of widely used general cognitive measures, such as the Montreal Cognitive Assessment (T-MoCA), for remote assessments.

Methods: In the Einstein Aging Study, a diverse community cohort (n = 428; mean age = 78.1; 66% female; 54% non-White), equivalence testing was used to examine concordance between the T-MoCA and the corresponding in-person MoCA assess- ment. Receiver operating characteristic analyses examined the diagnostic ability to dis- criminate between mild cognitive impairment and normal cognition. Conversion meth- ods from T-MoCA to the MoCA are presented.

Results: Education, race/ethnicity, gender, age, self-reported cognitive concerns, …

Using Verb Extension To Gauge Children’S Verb Meaning Construals: The Case Of Chinese, Weiyi Ma, Roberta Michnick Golinkoff, Lulu Song, Kathy Hirsh-Pasek

Publications and Research

Verb extension is a crucial gauge of the acquisition of verb meaning. In English, studies suggest that young children show conservative extension. An important test of whether an early conservative extension is a general phenomenon or a function of the input language is made possible by Chinese, a language in which verbs are more frequent and acquired earlier. This study tested whether 3-year-old Chinese children extended a group of familiar verbs that specify various ways to carry objects. Shown videos that portrayed typical, mid-typical, or atypical carrying actions (as verified by Chinese adults), children were asked to judge whether they …

The Non-Uniformity Of Chinese Wh-Indefinites Through The Lens Of Algebraic Structure, Zhuo Chen

Dissertations, Theses, and Capstone Projects

This dissertation investigates the non-uniformity of Chinese wh-indefinites. The different algebraic structures associated with the different wh-indefinites are shown to play a signif- icant role in determining their possible readings. Specifically, those wh-indefinites that are associated with an unordered algebraic structure can give rise to an epistemic reading in both positive and negative sentences. Those wh-indefinites that are associated with a structure of total ordering never have an epistemic reading. They have an existential reading in posi- tive sentences and generate an insignificance reading under a clausemate negation. Shenme ‘what’ is a special in that it straddles both types of …

Class Act: Symbolic Revolution And The Meaning Of College In Prison, Ruth E. Delaney

Dissertations, Theses, and Capstone Projects

The United States has gone through two transformations in the meaning of higher education in prison and the value of access for people in prison in the last 50 years and is now moving towards a third. The establishment of Pell grants in 1972 allowed for widespread access to higher education in prison, while the removal of those grants in 1994 effectively ended access. Federal policy makers are now poised to restore access to Pell grants to a broad swath of people in prison (Green, 2019; Krieghbaum, April 22, 2019; Krieghbaum, October 11, 2019). In this paper, I interpret the …

The One-Armed Viewer: Voyeurism And Masturbation In Nudist Imagery And Film Spectatorship, Benjamin Eleanor Adam

Dissertations, Theses, and Capstone Projects

Nudist magazines and newsletters were among the first commercial, legal, and widely-available images of nudity which circulated in the late Comstock Era. To evade censorship, producers developed framing strategies that obscured the sexualized nature of these images, even as they also enabled the viewing practices their sales relied upon. This dissertation traces these framing strategies as they evolved through nudist still-imagery, camp films, and nudie cuties, and considers the evolution of spectatorial pleasures associated with Russ Meyer's early nudie cuties.
