description: We review the topic of quantized vortices in multicomponent Bose-Einstein condensates of dilute atomic gases, with an emphasis on that in two-component condensates. First, we review the fundamental structure, stability and dynamics of a single vortex state in a slowly rotating two-component condensates. To understand recent experimental results, we use the coupled Gross-Pitaevskii equations and the generalized nonlinear sigma model. An axisymmetric vortex state, which was observed by the JILA group, can be regarded as a topologically trivial skyrmion in the pseudospin representation. The internal, coherent coupling between the two components breaks the axisymmetry of the vortex state, resulting in a stable vortex molecule (a meron pair). We also mention unconventional vortex states and monopole excitations in a spin-1 Bose-Einstein condensate. Next, we discuss a rich variety of vortex states realized in rapidly rotating two-component Bose-Einstein condensates. We introduce a phase diagram with axes of rotation frequency and the intercomponent coupling strength. This phase diagram reveals unconventional vortex states such as a square lattice, a double-core lattice, vortex stripes and vortex sheets, all of which are in an experimentally accessible parameter regime. The coherent coupling leads to an effective attractive interaction between two components, providing not only a promising candidate to tune the intercomponent interaction to study the rich vortex phases but also a new regime to explore vortex states consisting of vortex molecules characterized by anisotropic vorticity. A recent experiment by the JILA group vindicated the formation of a square vortex lattice in this system.

description: This paper deals with the non-manual mouth actions of
Swedish Sign Language, Svenskt teckenspråk (STS). Based on data
from the Swedish Sign Language Corpus and the Swedish Sign Language
as L2 Corpus, we compare the use of mouthings in deaf L1 as
well as hearing L2 signers. The use, distribution and frequency of
mouthings are explored and described quantitatively and qualitatively.
The results reveal some similarities as well as differences in
the use of mouthings between the groups. Furthermore, the analysis
reveals qualitative differences related to the properties of mouthings
i.e. full and reduced mouthings among L1 as well as L2 learners of
STS. Challenges of the analysis of mouthings will be discussed.

description: Homeland security against possible terrorist attacks involves making decisions under true uncertainty. Not only are we ignorant of the form, place, and time of potential terrorist attacks, we are also largely ignorant of the likelihood of these attacks. In this paper, we conceptualize homeland security under true uncertainty as society's immunity to unacceptable losses. We illustrate and analyze the consequences of this notion of security with a simple model of allocating a fixed budget for homeland security to defending the pathways through which a terrorist may launch an attack and to mitigating the damage from an attack that evades this defense. In this problem, immunity is the range of uncertainty about the likelihood of an attack within which the actual expected loss will not exceed some critical value. We analyze the allocation of a fixed homeland security budget to defensive and mitigative efforts to maximize immunity to alternative levels of expected loss. We show that the production of homeland security involves a fundamental trade-off between immunity and acceptable loss; that is, for fixed resources that are optimally allocated to defense and mitigation, increasing immunity requires accepting higher expected losses, and reducing acceptable expected losses requires lower immunity. Greater investments in homeland security allow society to increase its immunity to a particular expected loss, reduce the expected losses to which we are immune while holding the degree of immunity constant, or some combination of increased immunity to a lower critical expected loss.

description: This paper uses a meta-analysis to explore the relationship between hypothetical bias and the price respondents are asked to pay. For public goods, the results clearly indicate a difference in the price elasticity between hypothetical and actual payment conditions. Since the bias increases for larger dollar amounts, any simple guidelines, such as NOAA's "divide by two" rule of thumb, could be misleading. Future attempts to calibrate contingent valuation responses should reflect this price sensitivity.
Heat Capacity as A Witness of Entanglement

description: We demonstrate that the presence of entanglement in macroscopic bodies (e.g. solids) in thermodynamical equilibrium could be revealed by measuring heat-capacity. The idea is that if the system were in a separable state, then for certain Hamiltonians heat capacity would not tend asymptotically to zero as the temperature approaches absolute zero. Since this would contradict the third law of thermodynamics, one concludes that the system must contain entanglement. The separable bounds are obtained by minimization of the heat capacity over separable states and using its universal low-temperature behavior. Our results open up a possibility to use standard experimental techniques of solid state physics -- namely, heat capacity measurements -- to detect entanglement in macroscopic samples.

description: Dark sector particles with small electric charge, or millicharge, (mCPs) may lead to a variety of diverse phenomena in particle physics, astrophysics and cosmology. Assuming their possible existence, we investigate the accumulation and propagation of mCPs in matter, specifically inside the Earth. Even small values of millicharge lead to sizeable scattering cross sections on atoms, resulting in complete thermalization, and as a consequence, considerable build-up of number densities of mCPs, especially for the values of masses of GeV and higher when the evaporation becomes inhibited. Enhancement of mCP densities compared to their galactic abundance, that can be as big as $10^{14}$, leads to the possibility of new experimental probes for this model. The annihilation of pairs of mCPs will result in new signatures for the large volume detectors (such as Super-Kamiokande). Formation of bound states of negatively charged mCPs with nuclei can be observed by direct dark matter detection experiments. A unique probe of mCP can be developed using underground electrostatic accelerators that can directly accelerate mCPs above the experimental thresholds of direct dark matter detection experiments.

description: Time-periodic driving facilitates a wealth of novel quantum states and quantum engineering. The interplay of Floquet states and strong interactions is particularly intriguing, which we study using time-periodic fields in a one-dimensional quantum gas, modeled by a Luttinger liquid with periodically changing interactions. By developing a time-periodic operator algebra, we are able to solve and analyze the complete set of non-equilibrium steady states in terms of a Floquet-Bogoliubov ansatz and known analytic functions. Complex valued Floquet eigenenergies occur when multiples of driving frequency approximately match twice the dispersion energy, which correspond to resonant states. In experimental systems of Lieb-Liniger bosons we predict a change from powerlaw correlations to dominant collective density wave excitations at the corresponding wave numbers as the frequency is lowered below a characteristic cut-off.

description: Person re-identification (Re-ID) via gait features within 3D skeleton sequences is a newly-emerging topic with several advantages. Existing solutions either rely on hand-crafted descriptors or supervised gait representation learning. This paper proposes a self-supervised gait encoding approach that can leverage unlabeled skeleton data to learn gait representations for person Re-ID. Specifically, we first create self-supervision by learning to reconstruct unlabeled skeleton sequences reversely, which involves richer high-level semantics to obtain better gait representations. Other pretext tasks are also explored to further improve self-supervised learning. Second, inspired by the fact that motion's continuity endows adjacent skeletons in one skeleton sequence and temporally consecutive skeleton sequences with higher correlations (referred as locality in 3D skeleton data), we propose a locality-aware attention mechanism and a locality-aware contrastive learning scheme, which aim to preserve locality-awareness on intra-sequence level and inter-sequence level respectively during self-supervised learning. Last, with context vectors learned by our locality-aware attention mechanism and contrastive learning scheme, a novel feature named Constrastive Attention-based Gait Encodings (CAGEs) is designed to represent gait effectively. Empirical evaluations show that our approach significantly outperforms skeleton-based counterparts by 15-40% Rank-1 accuracy, and it even achieves superior performance to numerous multi-modal methods with extra RGB or depth information.

description: The Bak-Sneppen model displaying punctuated equilibria in biological evolution is studied on random complex networks. By using the rate equation and the random walk approaches, we obtain the analytic solution of the fitness threshold $x_c$ to be 1/(_f+1), where _f=/ (=) in the quenched (annealed) updating case, where is the n-th moment of the degree distribution. Thus, the threshold is zero (finite) for the degree exponent γ<3 (γ> 3) for the quenched case in the thermodynamic limit. The theoretical value x_c fits well to the numerical simulation data in the annealed case only. Avalanche size, defined as the duration of successive mutations below the threshold, exhibits a critical behavior as its distribution follows a power law, P_a(s) ~ s^{-3/2}.

description: We report the successful synthesis of FeSe$_{1-x}$S$_{x}$ single crystals with $x$ ranging from 0 to 1 via a hydrothermal method. A complete phase diagram of FeSe$_{1-x}$S$_{x}$ has been obtained based on resistivity and magnetization measurements. The nematicity is suppressed with increasing $x$, and a small superconducting dome appears within the nematic phase. Outside the nematic phase, the superconductivity is continuously suppressed and reaches a minimum $T_c$ at $x$ = 0.45; beyond this point, $T_c$ slowly increases until $x$ = 1. Intriguingly, an anomalous resistivity upturn with a characteristic temperature $T^*$ in the intermediate region of $0.31 \leq x \leq 0.71$ is observed. $T^{*}$ shows a dome-like behavior with a maximum value at $x$ = 0.45, which is opposite the evolution of $T_c$, indicating competition between $T^*$ and superconductivity. The origin of $T^*$ is discussed in detail. Furthermore, the normal state resistivity evolves from non-Fermi-liquid to Fermi-liquid behavior with S doping at low temperatures, accompanied by a reduction in electronic correlations. Our study addresses the lack of single crystals in the high-S doping region and provides a complete phase diagram, which will promote the study of relations among nematicity, superconductivity, and magnetism.

DIRECT AND MARKET EFFECTS OF ENFORCING EMISSIONS TRADING PROGRAMS: AN EXPERIMENTAL ANALYSIS

description: Since firms in an emissions trading program are linked together through a permit market, so too are their compliance choices. Thus, enforcement strategies for trading programs must account for not only the direct effects of enforcement on compliance and emissions decisions, but also the indirect effects that occur because changes in enforcement can induce changes in permit prices. This paper uses laboratory experiments to test for these direct and indirect market effects. Consistent with theoretical predictions, we find a direct effect of enforcement on individual violations, as well as a countervailing market effect through the permit price. Thus, the productivity of increased enforcement pressure to reduce noncompliance is partially offset by a countervailing price effect. Furthermore, there is no direct effect of enforcement on the emissions choices of firms, only a negative price effect. This suggests that the only way increased enforcement can have an impact on environmental quality is if it is large enough and applied widely enough to induce an increase in the equilibrium permit price.

OPTIMAL NONCOMPLIANCE IN EMISSIONS TRADING PROGRAMS

Year: 2004
Subjects: Environmental Economics and Policy

description: This paper characterizes optimal noncompliance for an emissions trading policy that seeks to achieve a given aggregate emissions target at least cost. The total costs of achieving the target consist of aggregate abatement costs, monitoring costs, and the expected costs of collecting penalties from noncompliant firms. Optimal noncompliance depends in large measure on whether the marginal penalty for individual violations is increasing or constant. The primary result of this work is that any policy that achieves an aggregate emissions target with a linearly increasing marginal penalty, regardless of whether it involves perfect or imperfect compliance, is more costly than an alternative policy that induces perfect compliance with a constant marginal penalty.

description: There is a growing interest in the relation between classical turbulence and quantum turbulence. Classical turbulence arises from complicated dynamics of eddies in a classical fluid. In contrast, quantum turbulence consists of a tangle of stable topological defects called quantized vortices, and thus quantum turbulence provides a simpler prototype of turbulence than classical turbulence. In this paper, we investigate the dynamics and statistics of quantized vortices in quantum turbulence by numerically solving a modified Gross-Pitaevskii equation. First, to make decaying turbulence, we introduce a dissipation term that works only at scales below the healing length. Second, to obtain steady turbulence through the balance between injection and decay, we add energy injection at large scales. The energy spectrum is quantitatively consistent with the Kolmogorov law in both decaying and steady turbulence. Consequently, this is the first study that confirms the inertial range of quantum turbulence.

description: In this paper, we study the so-called intermediate disorder regime for a directed polymer in a random environment with heavy-tail. Consider a simple symmetric random walk $(S_n)_{n\geq 0}$ on $\mathbb{Z}^d$, with $d\geq 1$, and modify its law using Gibbs weights in the product form $\prod_{n=1}^{N} (1+βη_{n,S_n})$, where $(η_{n,x})_{n\ge 0, x\in \mathbb{Z}^d}$ is a field of i.i.d. random variables whose distribution satisfies $\mathbb{P}(η>z) \sim z^{-α}$ as $z\to\infty$, for some $α\in(0,2)$. We prove that if $α< \min(1+\frac{2}{d},2)$, when sending $N$ to infinity and rescaling the disorder intensity by taking $β=β_N \sim N^{-γ}$ with $γ=\frac{d}{2α}(1+\frac{2}{d}-α)$, the distribution of the trajectory under diffusive scaling converges in law towards a random limit, which is the continuum polymer with Lévy $α$-stable noise constructed in the companion paper arXiv:2007.06484.

A fair bandwidth distribution algorithm with a bandwidth reservation extension
Creators: name: Sunna, Raed J.
Publisher: name: University of British Columbia
Year: 2009

description: The algorithm presented in this thesis is designed to provide all flows sharing an output link of a router with a fair share of the bandwidth, while at the same time guarantying a high total bandwidth utilization. This Fair Bandwidth Distribution algorithm (FBDA) is designed to work with already existing responsive (e.g. TCP) and nonresponsive (e.g. UDP) transport layer protocols. The basic idea in the algorithm is to use packet dropping to indicate to a specific flow that it is taking too much bandwidth and that it should slow down. All accepted packets are saved in one output buffer and are scheduled in a first-come first-service manner. Determining which packet should be dropped is done by assigning to each flow in the output queues of the router one per-connection variable. This variable is used to keep track of how much bandwidth the flow is consuming compared to its fair share since the last packet it lost. This same variable is also used with some upper thresholds to control nonresponsive and other aggressive flows.The average queue size is effectively controlled by providing an upper limit to the value of the average flow size (the average number of packets per flow in the queue) used in the different calculations. This is needed to have enough free buffer space for bursty traffic. An extension to the algorithm provides for allocating certain portions of the bandwidth to specific nonresponsive flows. This is done by using the same variable mentioned earlier as a counter to represent the number of packets that the flow can pass through the gateway in a specific period of time. If this variable reaches zero, all the packets for that flow will be dropped until the end of the current period. A very simple mechanism is designed to allow all the flows with a reserved bandwidth to share the same buffer space with all other flows, without overflowing the buffer. This will reduce the overhead and allow for optimal bandwidth utilization.

description: Significant difference between response to real and hypothetical valuation questions is often referred to as hypothetical bias. Some economists have had success with using "cheap talk" (which entails reading a script that explicitly highlights the hypothetical bias problem before participants make any decisions) as a means of generating unbiased responses in a referendum format. In this article, we test the robustness of cheap talk using a voluntary contribution mechanism with a provision point over a wide range of possible payment amounts. Our results confirm the existence of hypothetical bias, and suggest that cheap talk may eliminate hypothetical bias, but only for respondents facing higher payments.

description: What is the maximum number of copies of a fixed forest $T$ in an $n$-vertex graph in a graph class $\mathcal{G}$ as $n\to \infty$? We answer this question for a variety of sparse graph classes $\mathcal{G}$. In particular, we show that the answer is $Θ(n^{α_d(T)})$ where $α_d(T)$ is the size of the largest stable set in the subforest of $T$ induced by the vertices of degree at most $d$, for some integer $d$ that depends on $\mathcal{G}$. For example, when $\mathcal{G}$ is the class of $k$-degenerate graphs then $d=k$; when $\mathcal{G}$ is the class of graphs containing no $K_{s,t}$-minor ($t\geq s$) then $d=s-1$; and when $\mathcal{G}$ is the class of $k$-planar graphs then $d=2$. All these results are in fact consequences of a single lemma in terms of a finite set of excluded subgraphs.

description: This study focuses on the longstanding impoverishment of the rural South and three of its subregions-Appalachia, the Mississippi Delta, and the Black Belt. The poor quality of life in rural Appalachia and along the Mississippi Delta has been publically acknowledged by programs and commissions for improving conditions. However, the more comprehensive Black Belt subregion that links parts of Southern Appalachia and the Southern Delta has not received such regional policy attention. While the South as a whole is more rural and impoverished than other U.S. regions, this is largely due to the poor conditions in the Black Belt. In addition to region and rurality, a third feature of the pattern is race. It is in the Black Belt that the South's poor socioeconomic conditions are most concentrated. Policy and program attention are needed for regional solutions that take rurality and race into account along with demographic and other subregional characteristics.

description: We present a quantum algorithm to solve systems of linear equations of the form $A\mathbf{x}=\mathbf{b}$, where $A$ is a tridiagonal Toeplitz matrix and $\mathbf{b}$ results from discretizing an analytic function, with a circuit complexity of $poly(\log(κ), 1/\sqrtε, \log(N))$, where $N$ denotes the number of equations, $ε$ is the accuracy, and $κ$ the condition number. The \emph{repeat-until-success} algorithm has to be run $\mathcal{O}\left(κ/(1-ε)\right)$ times to succeed, leveraging amplitude amplification, and sampled $\mathcal{O}(1/ε^2)$ times. Thus, the algorithm achieves an exponential improvement with respect to $N$ over classical methods. In particular, we present efficient oracles for state preparation, Hamiltonian simulation and a set of observables together with the corresponding error and complexity analyses. As the main result of this work, we show how to use Richardson extrapolation to enhance Hamiltonian simulation, resulting in an implementation of Quantum Phase Estimation (QPE) within the algorithm with $1/\sqrtε$ circuit complexity instead of $1/ε$ and which can be parallelized. Furthermore, we analyze necessary conditions for the overall algorithm to achieve an exponential speedup compared to classical methods. Our approach is not limited to the considered setting and can be applied to more general problems where Hamiltonian simulation is approximated via product formulae, although, our theoretical results would need to be extended accordingly. All the procedures presented are implemented with Qiskit and tested for small systems using classical simulation as well as using real quantum devices available through the IBM Quantum Experience.

description: Many processes in nature seem to be entirely controlled by transition rates and the corresponding statistical dynamics. Some of them are in essence quantum, like the decay of excited states, the tunneling through barriers or the decay of unstable nuclei. Thus, starting from first principles, those systems should be analyzed on the basis of the Schroedinger equation. In the present paper we consider a two level system coupled to an environment which is basically described by an two-band energy scheme. For appropriately tuned environment parameters, the excitation probability of the two level system exhibits statistical dynamics, while the full system follows the coherent, unitary pure state evolution generated by the Schroedinger equation.

description: There is rapidly growing interest in the use of market-based (MB) instruments in environmental policy. The papers in this session discuss three relatively new areas for such policies: groundwater contamination, nonpoint source surface-water pollution and carbon sequestration. The papers point out the potential for MB policies in these areas, but significant challenges remain. This comment highlights challenges related to five issues: monitoring and enforcement, trading ratios, baselines, transaction costs, and risk and uncertainty. All these issues must be addressed before MB policies can take the full step from economic theory to regulatory reality.
BIOSAFETY AS AN ELEMENT OF NATIONAL SECURITY

description: In today’s increasingly interconnected world, the concept of national security extends beyond traditional military and geopolitical concerns to encompass a wide range of issues, including environmental and health-related threats. Among these, biosafety has emerged as a critical element of national security, as the spread of harmful biological agents—whether naturally occurring or human-engineered—poses significant risks to public health, ecosystems, and national stability. This thesis explores the importance of biosafety in national security frameworks, examining its role in preventing biological threats, the challenges it presents, and the policies and strategies needed to mitigate these risks.

description: The implications of the empirical signatures for the positivity of the strangeness magnetic moment $μ_s$, and the negativity of the strangeness contribution to the proton spin $Δ_s$, on the possible $uuds\bar s$ configurations of five quarks in the proton are analyzed. The empirical signs for the values of these two observables can only be obtained in configurations where the $uuds$ system is orbitally excited and the $\bar s$ quark is in the ground state. The configurations, in which the $\bar s$ is orbitally excited, which include the conventional $K^+Λ^0$ congfiguration, with the exception of that, in which the $uuds$ component has spin 2, yield negative values for $μ_s$. Here the strangeness spin $Δ_s$, the strangeness magnetic moment $μ_s$ and the axial coupling constant $G_A^s$ are calculated for all possible configurations of the $uuds\bar s$ component of the proton. In the configuration with $[4]_{FS}[22]_F[22]_S$ flavor-spin symmetry, which is likely to have the lowest energy, $μ_s$ is positive and $Δ_s\simeq G_A^s\simeq -1/3μ_s$.

description: A logistic growth equation with time and location varying parameters was used to model corn response to applied nitrogen. A nonlinear dummy-variable regression model provided a parsimonious representation of site and time effects on parameter values. The model was used to test for the equality of the mean marginal product of nitrogen fertilizer between locations on the coastal plain of North Carolina. Monte Carlo simulation and bootstrap simulation were used to construct finite sample covariance estimates. Results support rejection of the hypothesis that mean marginal products are equal when nitrogen is applied at 168 kg/ac. A comparison of bootstrapped errors and asymptotic errors suggests that results based on asymptotic theory are fairly reliable in this case.

Open architecture controllers : real-time capabilities and interoperability
Creators: name: Õtkũnc, Cemile Bũke

description: Open architecture controllers are used in manufacturing systems for providing reconfigurability, extendibility, and portability of control modules. One drawback of current open architecture controller standards is that they do not include specifications for real-time requirements. Another drawback is that it is not possible to use a control application defined for one standard on another open architecture controller. Furthermore, an application running on one open architecture controller cannot communicate with an application implemented using a different standard. In this thesis, the application programmers interfaces of two open architecture controllers, namely OSACA and ORTS, are examined in terms of their hard real-time specifications. Two interfaces are developed and implemented for exchanging data between ORTS, a small memory real-time operating system, and other open architecture control systems. The first interface provides a bridge between ORTS and the European initiated open architecture control standard, OSACA. This TCP/IP based interface enables data transfer between ORTS and OSACA applications which can be implemented on a wide range of different platforms. The second interface provides a bridge between ORTS and the open architecture CNC, ISG NC Kernel. The interface uses shared memory and is therefore advantageous for small memory, high speed applications such as intelligent machining, monitoring and control applications.
Moving away from singly-magic nuclei with Gorkov Green's function theory

description: Ab initio calculations of bulk nuclear properties (ground-state energies, root mean square charge radii and charge density distributions) are presented for seven complete isotopic chains around calcium, from argon to chromium. Calculations are performed within the Gorkov self-consistent Green's function approach at second order and make use of two state-of-the-art two- plus three-nucleon Hamiltonians, $NN$+$3N\text{(lnl)}$ and NNLO$_{\text{sat}}$. An overall good agreement with available experimental data is found, in particular for differential energies (charge radii) when the former (latter) interaction is employed. Remarkably, neutron magic numbers $N=28,32,34$ emerge and evolve following experimental trends. In contrast, pairing gaps are systematically underestimated. General features of the isotopic dependence of charge radii are also reproduced, as well as charge density distributions. A deterioration of the theoretical description is observed for certain nuclei and ascribed to the inefficient account of (static) quadrupole correlation in the present many-body truncation scheme. In order to resolve these limitations, we advocate the extension of the formalism towards incorporating breaking of rotational symmetry or, alternatively, performing a stochastic sampling of the self-energy.

We consider a robot which has $n$ arms such that each arm is of length 1+1 and has a rotational joint in the middle, and that the endpoint of the $k$-th arm is fixed to $Re^{\frac{2(k-1)π}ni}$. Generically, the configuration space is diffeomorphic to an orientable closed surface. Its genus is given by a topological way and a Morse theoretical way.
