description: We characterize the expressive power of quantum circuits with the pseudo-dimension, a measure of complexity for probabilistic concept classes. We prove pseudo-dimension bounds on the output probability distributions of quantum circuits; the upper bounds are polynomial in circuit depth and number of gates. Using these bounds, we exhibit a class of circuit output states out of which at least one has exponential state complexity, and moreover demonstrate that quantum circuits of known polynomial size and depth are PAC-learnable.

description: We consider independent electrons in a periodic crystal in their ground state, and turn on a uniform electric field at some prescribed time. We rigorously define the current per unit volume and study its properties using both linear response and adiabatic theory. Our results provide a unified framework for various phenomena such as the quantification of Hall conductivity of insulators with broken time-reversibility, the ballistic regime of electrons in metals, Bloch oscillations in the long-time response of metals, and the static conductivity of graphene. We identify explicitly the regime in which each holds.

description: The relative proximity of the recent gamma ray burst (GRB) 030329 resulted in a large gamma-ray fluence and in the brightest-ever afterglow (AG), hours after the burst, in the radio, optical and X-ray bands, permitting precise AG measurements, sensitive tests of models and an excellent occasion to investigate the association of GRBs with supernovae (SNe). The Cannonball (CB) model provides a good, simple and universal description of all AGs of GRBs of known redshift, so that it is straightforward to use it to predict what the expected SN signatures are. In the case of GRB 030329, 10 days after burst the AG should begin to reveal the lightcurve, spectrum and polarization of an underlying SN --akin to SN1998bw-- which will peak in the NIR/optical band around day 15. These effects will be easily observable if indeed SN1998bw is a good ``standard candle'' for GRB-associated SNe and if the so far unknown extinction in the host galaxy is not too large.

description: Background: The COVID-19 lockdown period was the 1st time all group exercise was paused by government legislation. This provided a unique opportunity to assess how lack of group exercise impacted physical activity habits and wellbeing. This study used a combination of the Social Identity Approach (SIA) and Self-Determination Theory (SDT) to examine UK runners’ motivation, physical activity, and well-being during the pandemic. Purpose: To understand how running social identities, autonomy, and competence were associated with participants’ motivation for physical activity and well-being during the COVID-19 lockdown. Methods: 602 runners living within the UK completed an online cross-sectional survey between the 15th-28th of June 2020. Participants completed self-reported measures about their demographics, running social identities, motivation, autonomy, competence, physical activity levels, and mental well-being. In addition, a sample of 138 participants also recorded behavioural data of their daily step count and total running mileage to compare April 2019 and April 2020. Results: Linear regressions demonstrated that identification with a running club was negatively predicted physical activity (β = -.39. p < .01) while shared runner identity positively predicted mental well-being (β = .24. p < .01. Competence positively predicted physical activity (β = .29. p < .01) and mental well-being (β = .28. p < .05). There was a statistically significant difference in daily step count and total running mileage between April 2019 and 2020 (p < .01); on average, participants took 1,700 fewer steps in April 2019 than April 2020, but increased their total running mileage by 12.26 miles. Conclusions: During the lockdown period participants decreased their daily step count but increased their total running mileage. The SDT variable competence, one’s perceived confidence and ability in a behaviour, was associated with maintenance of physical activity during lockdown. The SIA variables revealed that participants who identified with their running group decreased in physical activity during the lockdown period. However, despite the lack of physical group interaction, participants could still feel a shared psychological connection to the running community as a whole which was positively associated with mental well-being. This study revealed how one’s perceived competence in running and group memberships may be associated with physical activity levels and mental well-being during the lockdown period.

description: The Hamiltonian of optical fields in a nonlinear dispersive fiber is studied. Quantum field fluctuations are spontaneously created close to an optical event horizon through the analog Hawking effect. The simplest model is considered for an optical black-hole laser, where the Hawking radiation is produced and amplified inside a cavity formed by two horizons: a black hole and a white hole. It is found that resonant Hawking radiation originates from a discrete set of instabilities and tunnels out of the horizons. Finally, the numerical results are compared with the resonance and instability conditions and a phenomenological model is developed to give a clear physical picture.

description: This paper aims at understanding the economic performance of craftsmen cooperatives during the crisis period. These cooperatives have the distinctive feature of being supply cooperatives. We use an exhaustive dataset for the French craftsmen cooperatives (2004-2014). We estimate Bayesian Translog econometric models in order to underline the impact of the 2008 crisis on these cooperatives. On the one hand, cooperatives’ turnover contracts during the crisis, the effect is lower for elder cooperatives and varies across sectors. On the other hand, there is convergence towards the mean for the various generations of cooperatives. Theses findings are robust to alternative econometric specifications.

description: Objective Some young healthy-weight (HW) toddlers and preschoolers develop overweight/obesity (OW/OB) in later childhood. Our study aims to identify demographic risk factors for OW/OB incidence in 8-10-year[y]-old children with HW history between ages 2-5y.Methods This retrospective longitudinal cohort study used data from the electronic medical record at an urban tertiary childrens hospital. 2-5-year-olds born between 10/2007-05/2011 were included if they (1) had an outpatient visit with anthropometric data at 2-5y and 8-10y & (2) had HW from ages 2-5y. Predictor variables were sex, race/ethnicity, language, insurance & zip code. Main outcome was body mass index (BMI) percentile (%ile) category at 8-10y, determined by the highest %ile reached: HW (5-84%ile), OW (85-94%ile), mild-moderate OB (95-98%ile), severe OB (99%ile). Statistical analyses included descriptive frequencies and multinomial logistic regression.Results Of 7043 initially HW patients, 1070 (15%) developed OW and 863 (12%) developed OB by 8-10y. Severe OB risk factors were African-American race (OR 4.66; 2.45-8.67), Hispanic ethnicity (OR 2.99; 1.61-5.55) & public insurance (OR 3.69; 2.19- 6.24). Female sex was protective (OR 0.54; 0.36-0.79).Conclusion One-quarter of previously HW young children developed OW/OB by age 8-10y; African-American, Hispanic, male and publicly insured children have the highest risk of developing severe OB. While factors associated with OW/OB in this cohort are familiar, these findings suggest that clinicians should direct specific attention to young HW patients with these risks to prevent excessive BMI increase.

description: Background: It has been suggested that physical activity (PA) declined and sedentariness increased during the Covid-19 lockdown. Purpose: In France, a surveillance system using repeated surveys has been set up during lockdown, to study adult health behaviours, including PA and sedentariness. Methods: A sample of 2,000 adults were interviewed online. Representativeness was ensured by quota sampling and adjustment on census data. The prevalence of insufficient PA (<30 min/day), noteworthy sedentariness (sitting time >7 hours/day) and the frequency of sitting time breaks were assessed and analysed, with their associations with sociodemographic and mental health variables. Reported changes in PA and sitting time compared to before lockdown were analysed using multivariate models. Results: During the lockdown, 51% of the adults had insufficient PA, 33% reported a noteworthy sedentariness, and 55% did not break sitting time at the recommended frequencies. Compared to before lockdown, 47% reported decreasing their PA and 61% increasing their daily sitting time. Insufficient PA was more prevalent among adults with low socioeconomic status; but the decline in PA affected the higher socioeconomic categories. All these factors were associated, differently by gender, with anxiety, depression or sleep disorders. Conclusions: There was a decline of PA and an increase of sedentariness in French adults during the COVID-19 lockdown. It highlights the importance of promoting an active lifestyle in such a situation, in order to maintain the physical and mental health of the population.

description: Algorithmic (including AI/ML) decision-making artifacts are an established and growing part of our decision-making ecosystem. They are indispensable tools for managing the flood of information needed to make effective decisions in a complex world. The current literature is full of examples of how individual artifacts violate societal norms and expectations (e.g. violations of fairness, privacy, or safety norms). Against this backdrop, this discussion highlights an under-emphasized perspective in the literature on assessing value misalignment in AI-equipped sociotechnical systems. The research on value misalignment has a strong focus on the behavior of individual tech artifacts. This discussion argues for a more structured systems-level approach for assessing value-alignment in sociotechnical systems. We rely primarily on the research on fairness to make our arguments more concrete. And we use the opportunity to highlight how adopting a system perspective improves our ability to explain and address value misalignments better. Our discussion ends with an exploration of priority questions that demand attention if we are to assure the value alignment of whole systems, not just individual artifacts.

description: We describe a new effect in semiconductor spintronics that leads to dissipationless spin-currents in paramagnetic spin-orbit coupled systems. We argue that in a high mobility two-dimensional electron system with substantial Rashba spin-orbit coupling, a spin-current that flows perpendicular to the charge current is intrinsic. In the usual case where both spin-orbit split bands are occupied, the spin-Hall conductivity has a universal value.

description: A growing number of studies in finance and economics seek to explain insurance choices us- ing the assumptions advanced by behavioral economics. One recent example in agricultural economics is the use of cumulative prospect theory (CPT) to explain farmer choices regarding crop insurance coverage levels (Babcock, 2015). We build upon this framework by deriving willingness to pay (WTP) for insurance programs under alternative assumptions, thus extend- ing the model to incorporate farmer decisions regarding whether or not to purchase insurance. Our contribution is twofold. First, we study the sensitivity of farmer WTP for crop insurance to the inclusion of CPT parameters. We find that loss aversion and probability distortion in- crease WTP for insurance while risk aversion decreases it. Probability distortion in losses plays a particularly important role. Second, we study the impact of yield distribution skewness on farmer WTP assuming CPT preferences. We find that WTP decreases when the distribution of yields moves from negatively- to positively-skewed and that the combined effect of proba- bility weighting in losses and skewness has a large negative impact on farmer WTP for crop insurance.

description: It is my understanding that the reason for this conference is to determine the constraints to expanded consumption of US beef in Japan. There are, of course, many variables to consider. You can image that I, as an animal nutritionist, and specializing in ruminants, would like to concentrate on -- and please, no pun or double meaning intended -- the production side. But, rather than surcumb to a natural desire, I will address most of my talk to the consumption side as that is where I feel the major constraints lie. This approach is intended to complement Dr. Mari's paper, not supplement it even though there will undoubtedly be some overlap since we did not visit about our topics previous to this conference. Hopefully, there will be questions about production and how it relates to US beef exports to Japan.

Using the fluctuation-dissipation theorem it is shown that deterministic calculations of the governing fluid and solid equations can be used in a straightforward manner to directly calculate the stochastic response that would be measured in experiment. We use this approach to investigate the fluid coupled motion of single and multiple cantilevers with experimentally motivated geometries.

description: We analyze the stability of time-reversal (${\mathcal T}$) and lattice four-fold ($C_4$) symmetry breaking three-dimensional higher-order topological (HOT) Dirac semimetals (DSMs) and the associated one-dimensional hinge modes in the presence of random pointlike charge impurities. Complementary real space numerical and momentum space renormalization group (RG) analyses suggest that a HOTDSM, while being a stable phase of matter for sufficiently weak disorder, undergoes a continuous quantum phase transition into a trivial metal at finite disorder. However, the corresponding critical exponents (numerically obtained from the scaling of the density of states) are extremely close to the ones found in a dirty, but first-order DSM that on the other hand preserves ${\mathcal T}$ and $C_4$ symmetries, and support two Fermi arc surface states. This observation suggests an emergent \emph{superuniversality} (insensitive to symmetries) in the entire family of dirty DSMs, as also predicted by a leading-order RG analysis. As a direct consequence of the bulk-boundary correspondence, the hinge modes in a system with open boundaries gradually fade away with increasing randomness, and completely dissolve in the trivial metallic phase at strong disorder.

description: Background: Given the multiple positive effects of physical activity (PA) in old age, infection control measures during the COVID-19 pandemic have had paradoxical effects, particularly in nursing homes: measures contribute to the protection of vulnerable residents, and they result in residents becoming socially isolated, exposed to psychological stress, and physically declining due to increased sedentariness. Purpose: To analyze the options and challenges for PA promotion in LTC facilities, as (pseudo-) 'total' institutions in Goffman’s sense, under current pandemic conditions. Methods: Mixed-method study in eight LTC facilities in Southern Germany, based upon semi-structured interviews with executive and nursing staff (n=31), documents, such as nursing concepts, mission statements, and weekly activity plans, a photovoice study (n=27 participants, and n=169 photographs), and systematic observation on-sites (200hrs in 2020, 625hrs in 2021). We interpreted data through reflexive thematic analysis. Results: PA promotion is not integrated into organizational structure and culture. Nursing homes represent pseudo-total institutions, focused on caring for and protecting vulnerable people, rather than empowering residents as agents of their well-being and context and enabling them to age in a self-determined way. This trend is further exacerbated by a pandemic event. Conclusions: While nursing homes often demonstrate high levels of coping belief, the long-term effects of COVID-19 on PA promotion remain unclear, given the absence of external actors and lack of integration of PA promotion into organizational structure and culture.

description: We propose a solvable model of a one-dimensional harmonic oscillator quantum gas of two sorts of particles, fermions or bosons, which allows to describe the formation of pairs due to a suitable pair interaction. These pairs we call "pseudo-bosons" since the system can be approximated by an ideal bose gas for low temperatures. We illustrate this fact by considering the specific heat and the entropy function for N=8 pairs. The model can also be evaluated in the thermodynamic limit if the harmonic oscillator potential is suitable scaled.

description: We use a physically motivated semi-analytic model, based on the mass function of dark matter halos, to predict the number of radio-loud quasars as a function of redshift and luminosity. Simple models in which the central BH mass scales with the velocity dispersion of its host halo as M(bh) sigma(halo)^5 have been previously found to be consistent with a number of observations, including the optical and X-ray quasar luminosity functions. We find that similar models, when augmented with an empirical prescription for radio emission, overpredict the number of faint (10 micro-Jy) radio sources by 1-2 orders of magnitude. This translates into a more stringent constraint on the low-mass end of the quasar black hole mass function than is available from the Hubble and Chandra Deep Fields. We interpret this discrepancy as evidence that black holes with masses below 10^7 Msun are either rare or are not as radio-loud as their more massive counterparts. Models that exclude BHs with masses below 10^7 Msun are in agreement with the deepest existing radio observations, but still produce a significant tail of high-redshift objects. In the 1-10GHz bands, at the sensitivity of 10 micro-Jy, we find surface densities of 100, 10, and 0.3 deg^-2 for sources located at z>6, 10, and 15, respectively. The discovery of these sources with instruments such as the Allen Telescope Array (ATA), Extended Very Large Array (EVLA), and the Square Kilometer Array (SKA) would open a new window for the study of supermassive BHs at high redshift. We also find surface densities of 0.1 deg^-2 at z > 6 for mJy sources that can be used to study 21 cm absorption from the epoch of reionization. We suggest that, although not yet optically identified, the FIRST survey may have already detected 10^3-10^4 such sources.

description: Rapid economic growth has led to a rapid increase in beef consumption in both Taiwan and South Korea. Although increasing, beef production has lagged behind consumption providing an incentive to import. A number of barriers, however, currently limit U.S. access to those markets. The research required to reduce or eliminate each barrier is discussed.

description: We calculate gravitational perturbation quasinormal modes (QNMs) of non-singular Bardeen black holes (BHs) and singularity-free BHs in conformal gravity and examine their spectra in wave dynamics comparing with standard BHs in general relativity. After testing the validity of the approximate signal-to-noise ratio (SNR) calculation for different space based interferometers, we discuss the SNR of non-singular BHs in single-mode gravitational waveform detections in LISA, TianQin and TaiJi. We explore the impact of the Bardeen parameter and the conformal factor on the behavior of the SNR and find that in comparison with the standard Schwarzschild BHs, the increase of non-singular parameters leads to higher SNR for more massive non-singular BHs. We also examine the effect of the galactic confusion noise on the SNR and find that a dip appears in SNR due to such noise. For non-singular BHs, with the increase of the non-singular parameters the dip emerges for more massive BHs. It suggests a wider range of mass of non-singular black holes whose SNR will not be lowered by galactic noise, which implies the SNR for the super massive black holes centered at our galaxy will less likely to be influenced by galactic noise in non-singular black holes models than singular case in general relativity. We conduct Fisher analysis which suggests that the non-singular black holes parameters can be detected accurately with measurement errors as small as $\sim10^{-4}-10^{-5}$. The detections of non-singular BHs are expected to be realized more likely by LISA or TaiJi.

description: We explore the dynamics of entanglement in classically chaotic systems by considering a multiqubit system that behaves collectively as a spin system obeying the dynamics of the quantum kicked top. In the classical limit, the kicked top exhibits both regular and chaotic dynamics depending on the strength of the chaoticity parameter $κ$ in the Hamiltonian. We show that the entanglement of the multiqubit system, considered for both bipartite and pairwise entanglement, yields a signature of quantum chaos. Whereas bipartite entanglement is enhanced in the chaotic region, pairwise entanglement is suppressed. Furthermore, we define a time-averaged entangling power and show that this entangling power changes markedly as $κ$ moves the system from being predominantly regular to being predominantly chaotic, thus sharply identifying the edge of chaos. When this entangling power is averaged over initial states, it yields a signature of global chaos. The qualitative behavior of this global entangling power is similar to that of the classical Lyapunov exponent.

description: Background: There has been some effort to understand changes in recreational walking in Ireland during the COVID-19 pandemic period, yet little is known about recreational walking trail usage during the same period. Purpose: To use footfall count data and other forms of open-source mobility data to describe trends in trail usage in Ireland before and during the COVID-19 pandemic. Methods: Footfall count data were gathered from passive infra-red (PIR) sensors on 33 Irish walking trails and analysed between January 2019 and December 2020. Google Community Mobility Report (GCMR) data were also analysed to corroborate the footfall count data. Descriptive statistics were employed to highlight trends in footfall over time. Results: Total footfall counts increased by 5% between 2019 and 2020 on the trails included in this analysis. During phases of movement restrictions, trails that were <2km from urban areas were more frequently used than more remote trails. GCMR data from park areas mirrored findings found within the footfall analysis. Mean footfall on trails was 29% higher in December 2020 (when movement restrictions were lifted) than December 2019. Conclusions: The conclusions of this study are twofold. Firstly, openly available data, such as aggregated mobility data can be used to corroborate findings from PIR sensors. Secondly, the COVID-19 pandemic has left a legacy of increased recreational walking trail usage in Ireland, especially on trails closer to urban areas. There is now an opportunity to sustain this increase in trail usage through better understanding of the determinants of trail use. Funding: This study is part of a PhD project which is co-funded by Waterford Institute of Technology and Get Ireland Walking.

description: Magnetic skyrmions are promising candidates for future storage devices with a large data density. A great variety of materials have been found that host skyrmions up to the room-temperature regime. Lorentz microscopy, usually performed in a transmission electron microscope (TEM), is one of the most important tools for characterizing skyrmion samples in real space. Using numerical calculations, this work relates the phase contrast in a TEM to the actual magnetization profile of an isolated Neel or Bloch skyrmion, the two most common skyrmion types. Within the framework of the used skyrmion model, the results are independent of skyrmion size and wall width and scale with sample thickness for purely magnetic specimens. Simple rules are provided to extract the actual skyrmion configuration of pure Bloch or Neel skyrmions without the need of simulations. Furthermore, first differential phase contrast (DPC) measurements on Neel skyrmions that meet experimental expectations are presented and showcase the described principles. The work is relevant for material sciences where it enables the engineering of skyrmion profiles via convenient characterization.

description: Background: Restrictions imposed to curb the spread of COVID-19 have limited many opportunities for physical activity. Purpose: This study investigated physical activity and its associated barriers and enablers during the first two phases of COVID-19 restrictions in Ireland. Methods: An online survey collated data from Irish adults at two timepoints, the first during COVID-19 restrictions in May 2020 (Wave 1) and the second during restrictions in November 2020 (Wave 2). Logistic regression (Bayesian lasso) determined the main barriers for being less active than usual and enablers for being more active than usual during restrictions. Results: A total of 2064 adults participated (Wave 1:1260, Wave 2:804, 26% male). During Wave 1 restrictions, 46% of participants reported that they were more active than usual and 54% met the national physical activity guidelines. During Wave 2, 26% reported they were more active than usual (p<0.001) and the percentage meeting the guidelines decreased to 42% (p=0.01). Being advised to remain indoors, being unable to meet friends and their usual means of exercise being unavailable were predictive of being less active than usual. Having more time, a positive view on the importance of exercise and finding new ways to be active were predictive of being more active than usual. Conclusions: Physical activity of Irish adults decreased during consecutive periods of COVID-19 restrictions. Home based activities and supporting access to physical activity with social support from others appear important. Funding: Nil.

description: Background: National lockdowns were implemented in numerous countries around the globe in order to reduce COVID-19 transmission, affecting many aspects of living due to social distancing, isolation and home confinement. Purpose: The aims of this study were to evaluate changes in physical activity and sitting in response to the first COVID-19 lockdown in England and factors associated with these changes. Methods: An online survey was completed by 818 adults between 29 April and 13 May 2020. T-tests compared physical activity levels (MET-min/week) and X2 compared the proportion of participants engaging in low (<8 hours/day) and high sitting (≥8 hours/day) before and during lockdown. Logistic regression explored factors associated with physical activity and sitting during lockdown. Results: There was an increase in physical activity by 302 (155, 457) MET-min/week during lockdown (p<0.001). There were 19.81 and 5.83 higher odds of low physical activity for individuals with low and moderate levels pre-lockdown. Being higher educated and non-White ethnicity were associated with 1.70 higher and 0.24 lower odds of physical activity, respectively. More participants engaged in high sitting during lockdown than before (29% and 41%, respectively, p<0.001). High pre-lockdown sitting and being aged 40-59 years were associated with increased odds of high sitting during lockdown. Conclusions: Physical activity decreased and sitting increased during lockdown. Individuals with lower physical activity and higher sitting pre-lockdown in addition to lower education level, non-White ethnicity and middle-aged were more likely to engage in low physical activity and high sitting.

description: World War II marked the beginning of a new period in business education in the United States. DUring and immediately after the war years there was a great demand for skilled clerical workers. Businessmen complained that the beginning workers they received from schools were not adequately trained to meet the requirements of modern business office operation. The newly employed workers, graduates of public and private business education courses, had received training in some or all of the courses that were then considered adequate to produce competent office workers: stenography, bookkeeping, and office practice. Few of the new employees had received training in basic business practices, or were familiar with the economics or actual operation of modern day businesses.
