Mean-Field Description of Cooperative Scattering by Atomic Clouds
Creators: name: Piovella, Nicola
Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by an uniform laser, including the initial build-up, the steady-state and the decay after the laser is switched off. We show that the mean-field model does not describe subradiant scattering, due to negative interference of the photons scattered by $N$ discrete atoms.

Book Review: Successful Negotiating in Local Government
Creators: name: Fischman, Gail
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Book review of: Successful Negotiating in Local Government: Negotiation: It occurs every day in local government offices. Whether it is the city negotiating with i a local interest group or a planner talking with the developer of the new downtown office center, negotiation has taken on a whole new meaning to local governments. Increasingly, complex government interests and the high cost of unresolved conflicts has made negotiation an essential skill which all local government administrators and managers must possess. Since federal funds are being withdrawn from city budgets, the private sector is playing a more important role in city development and finance. Administrators have to be prepared to negotiate with supervisors, staff, department heads, and elected officials, as well as with outside individuals and agencies. Managers deal daily with resource allocation questions, land use disputes, and social tensions, for example. Negotiation may take place outside the local jurisdiction — in state, regional, or federal arenas. Local government officials must be able to feel confident when dealing with their colleagues in both the public and private sectors. Successful Negotiation in Local Government offers a selection of current essays on the subject of negotiation in the local government setting. It provides a compendium of the latest tools and techniques of negotiating, while also describing the psychology, dynamics, and current language of the negotiation process.

Distributed Control and Optimization of DC Microgrids: A Port-Hamiltonian Approach

Subjects: subject: Optimization and Control (math.OC)

description: This article proposes a distributed secondary control scheme that drives a dc microgrid to an equilibrium point where the generators share optimal currents, and their voltages have a weighted average of nominal value. The scheme does not rely on the electric system topology nor its specifications; it guarantees plug-and-play design and functionality of the generators. First, the incremental model of the microgrid system with constant impedance, current, and power devices is shown to admit a port-Hamiltonian (pH) representation, and its passive output is determined. The economic dispatch problem is then solved by the Lagrange multipliers method; the Karush-Kuhn-Tucker conditions and weighted average formation of voltages are then formulated as the control objectives. We propose a control scheme that is based on the Control by Interconnection design philosophy, where the consensus-based controller is viewed as a virtual pH system to be interconnected with the physical one. We prove the regional asymptotic stability of the closed-loop system using Lyapunov and LaSalle theorems. Equilibrium analysis is also conducted based on the concepts of graph theory and economic dispatch. Finally, the effectiveness of the presented scheme for different case studies is validated with a test microgrid system, simulated in both MATLAB/Simulink and OPAL-RT environments.

How Are We Doing? A Look at the Practice of Planning for Sustainable Development
Creators: name: Manta, Maria
name: Berke, Philip R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1998

description: The concept of sustainable development poses special challenges in the land use planning field as planning is fundamentally connected to the core themes found in the sustainability literature. These themes, often referred to as the three E's are: environmental protection, social equity, and economic development. From a local planning perspective, the themes are all affected by "what gets built and where." In the field of planning, present unsustainable land use patterns are noted as an indicator of larger societal sustainability problems. Calthorpe, for example, asserts that "[s]ettlement patterns are the physical foundation of our society and like our society, they are becoming more and more fractured" (Calthorpe 1993:16). Land use planning is also seen as the principal forum for addressing sustainability concerns and promoting fundamental sustainable principles (Beadey 1995; Rees 1995; Thomas 1994). Rees, for example, notes: In this increasingly fragmented and specialized world, planning is the one academic discipline and professional pursuit that explicitly attempts to be holistic or at least integrative at the level of society as a whole. At its best, planning provides a context in which the specialized knowledge of other disciplines comes together and begins to make unified sense. (Rees 1995:355) The primary manner in which planning can bring together and put into action the themes of sustainability is in the community comprehensive plan. The comprehensive planning process and subsequent plan provide a vehicle for the embodiment of sustainable development themes on a community level.

A Comparison of Land Use Legislation in Western North Carolina and Vermont
Creators: name: Orsbon, Benjamin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1975

description: Recreational development caught Western North Carolina and Vermont unprepared to guide and manage growth. When shoddy construction and land speculation began to create environmental and social problems, the local citizenry became alarmed. These two relatively isolated areas had never experienced such an influx of outsiders; yet, both hoped new construction would revive their sleeping economies. Citizens of Western North Carolina and Vermont have existed outside the economic mainstream. Partially because of this fact, both underdeveloped areas still contain valuable scenic resources demanded by affluent outsiders, and they remain dependent on the recreation-hungry urban areas for much of the capital investment in their rural economies.

Perturbative Corrections to $Λ_b \to Λ$ Form Factors from QCD Light-Cone Sum Rules

description: We compute radiative corrections to $Λ_b \to Λ$ from factors, at next-to-leading logarithmic accuracy, from QCD light-cone sum rules with $Λ_b$-baryon distribution amplitudes. Employing the diagrammatic approach factorization of the vacuum-to-$Λ_b$-baryon correlation function is justified at leading power in $Λ/m_b$, with the aid of the method of regions. Hard functions entering the factorization formulae are identical to the corresponding matching coefficients of heavy-to-light currents from QCD onto soft-collinear effective theory. The universal jet function from integrating out the hard-collinear fluctuations exhibits richer structures compared with the one involved in the factorization expressions of the vacuum-to-$B$-meson correlation function. Based upon the QCD resummation improved sum rules we observe that the perturbative corrections at ${\cal O}(α_s)$ shift the $Λ_b \to Λ$ from factors at large recoil significantly and the dominant contribution originates from the next-to-leading order jet function instead of the hard coefficient functions. Having at hand the sum rule predictions for the $Λ_b \to Λ$ from factors we further investigate several decay observables in the electro-weak penguin $Λ_b \to Λ\, \ell^{+} \ell^{-}$ transitions in the factorization limit (i.e., ignoring the "non-factorizable" hadronic effects which cannot be expressed in terms of the $Λ_b \to Λ$ from factors), including the invariant mass distribution of the lepton pair, the forward-backward asymmetry in the dilepton system and the longitudinal polarization fraction of the leptonic sector.

description: Transformer and its variants are a powerful class of architectures for sequential recommendation, owing to their ability of capturing a user's dynamic interests from their past interactions. Despite their success, Transformer-based models often require the optimization of a large number of parameters, making them difficult to train from sparse data in sequential recommendation. To address the problem of data sparsity, previous studies have utilized self-supervised learning to enhance Transformers, such as pre-training embeddings from item attributes or contrastive data augmentations. However, these approaches encounter several training issues, including initialization sensitivity, manual data augmentations, and large batch-size memory bottlenecks. In this work, we investigate Transformers from the perspective of loss geometry, aiming to enhance the models' data efficiency and generalization in sequential recommendation. We observe that Transformers (e.g., SASRec) can converge to extremely sharp local minima if not adequately regularized. Inspired by the recent Sharpness-Aware Minimization (SAM), we propose SAMRec, which significantly improves the accuracy and robustness of sequential recommendation. SAMRec performs comparably to state-of-the-art self-supervised Transformers, such as S$^3$Rec and CL4SRec, without the need for pre-training or strong data augmentations.
Understanding topological phase transition in transition metal dichalcogenides

description: Despite considerable interest in layered transition metal dichalcogenides (TMDs), such as MX2 with M = (Mo, W) and X = (S, Se, Te), the physical origin of their topological nature is still poorly understood. In the conventional view of topological phase transition (TPT), the non-trivial topology of electron bands in TMDs is caused by the band inversion between metal d and chalcogen p orbital bands, where the former is pulled down below the latter. Here, we show that, in TMDs, the TPT is entirely different from the conventional speculation. In particular, MS2 and MSe2 exhibits the opposite behavior of TPT, such that the chalcogen p orbital band moves down below the metal d orbital band. More interestingly, in MTe2, the band inversion occurs between the metal d orbital bands. Our findings cast doubts on the common view of TPT and provide clear guidelines for understanding the topological nature in new topological materials to be discovered.

description: In this paper, we compute the embedded contact homology (ECH) capacities of the disk cotangent bundles $D^*S^2$ and $D^*\mathbb{R} P^2$. We also find sharp symplectic embeddings into these domains. In particular, we compute their Gromov widths. In order to do that, we explicitly calculate the ECH chain complexes of $S^*S^2$ and $S^* \mathbb{R} P^2$ using a direct limit argument on the action inspired by Bourgeois's Morse-Bott approach and ideas from Nelson-Weiler's work on the ECH of prequantization bundles. Moreover, we use integrable systems techniques to find explicit symplectic embeddings. In particular, we prove that the disk cotangent bundles of a hemisphere and of a punctured sphere are symplectomorphic to an open ball and a symplectic bidisk, respectively.

A Possible Dynamical Origin of the Vertical Metallicity Gradient in the Milky Way Bulge
Creators: name: , Chen
name: , Shen
Publisher: name: Zenodo
Year: 2023
Subjects: Galactic bulg

description: The existence of the vertical metallicity gradient in our Milky Way bulge has been shown clearly by observations. However, this important result has not been well understood in present secular evolution models for the Milky Way. We build a secularly evolved N-body model in which a pure disk self-consistently forms a boxy/peanut bulge via the bar and buckling instability. We find that the vertical metallicity gradient is set up by a two-step mechanism if there exists an initial radial metallicity gradient: the outer (more metal-poor) particles move inward via bar instability and got vertically heated the most in the bar formation and buckling event, than the initially inner particles (more metal-rich). The hotter metal-poor population is distributed in a larger spatial region, and therefore the fraction of the metal-rich population decreases with higher latitude. The mapping between the initial radial gradient and final vertical gradient is linear, indicating that the vertical gradient encodes the galactic dynamical evolution history and the stellar position in the progenitor galaxy. This two-step mechanism for the vertical metallicity gradient must be in action in other more sophisticated disk models, and may constitute an important aspect of the secular evolution. Our simple model can generate the chemo-kinematic relation and asymmetric spatial metallicity distribution of the Galactic bulge. We also find that even such a simple model could result in a multimodal metallicity distribution, which is often regarded as a prediction of the multi-disk scenario. We also discuss the limitations of this simple model.

description: Short planning articles. Includes: HAZARD MITIGATION PLANNING: This Fall, North Carolina was spared the full force of Hurricane Diana. Diana's merciful outcome saved the state's coastal properties from catastrophic damage. While the extent of this hurricane's effect was less than originally expected, its landfall dramatized the need to plan for natural hazards and prepare coastal policies which will minimize their future impacts. Current research at the University of North Carolina's Center for Urban and Regional Studies is focusing on the mitigation of hurricane and coastal storm damages. A grant from the National Science Foundation supports this research. The study will examine the use of pre-disaster and post-disaster reconstruction development management programs and policies as a basis for reducing hurricane-inflicted property damage and loss of life. 1984 LAND USE CONGRESS: A SUMMARY OF PROCEEDINGS: On October 18, 1984, the Land Use Congress' annual conference addressed the topic of changing land uses in North Carolina. Entitled "Urban-Rural Development: What's Happening in North Carolina? What Do We Think About It?", the conference featured four debates in which guest speakers were asked to argue the merits/problems associated with the continued growth and changing land use in North Carolina.

Superfarms and the Coastal Environment: An In-Depth Look at a Large-scale Problem
Creators: name: Pugh, Mary Joan Manley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1976

description: Ever since white men have inhabited the area, the vast swampy reaches of North Carolina's Albemarle- Pamlico Peninsula have been considered a wasteland, useful only for logging and an occasional small farming venture. Over the last few years, however, great changes have been in the making for this long disregarded region. Spurred by increasing grain prices and postwar advances in farm technology, a number of large corporations have bought up vast amounts of acreage in the coastal area with the idea of conducting large-scale agricultural operations. Whether "superfarms" on the coast are a blessing or a curse has yet to be determined. Historically, the region has been economically depressed. Attempts at small scale farming have consistently failed. Thus, large scale farm ventures are looked upon as the solution to economic woes. Further, agricultural experts view the farms as posing no serious threat to the environment but, instead, as affording a great opportunity for converting a wasteland into profitable farmland. Environmentalists, however, are worried about the possible adverse impacts on the immediate wetland area and, more importantly, on the surrounding estuaries and marshlands which provide spawning and nursery areas for shellfish and commercial fisheries.

description: We study the privacy implications of training recurrent neural networks (RNNs) with sensitive training datasets. Considering membership inference attacks (MIAs), which aim to infer whether or not specific data records have been used in training a given machine learning model, we provide empirical evidence that a neural network's architecture impacts its vulnerability to MIAs. In particular, we demonstrate that RNNs are subject to a higher attack accuracy than feed-forward neural network (FFNN) counterparts. Additionally, we study the effectiveness of two prominent mitigation methods for preempting MIAs, namely weight regularization and differential privacy. For the former, we empirically demonstrate that RNNs may only benefit from weight regularization marginally as opposed to FFNNs. For the latter, we find that enforcing differential privacy through either of the following two methods leads to a less favorable privacy-utility trade-off in RNNs than alternative FFNNs: (i) adding Gaussian noise to the gradients calculated during training as a part of the so-called DP-SGD algorithm and (ii) adding Gaussian noise to the trainable parameters as a part of a post-training mechanism that we propose. As a result, RNNs can also be less amenable to mitigation methods, bringing us to the conclusion that the privacy risks pertaining to the recurrent architecture are higher than the feed-forward counterparts.

description: We model the decoherence and dephasing of nitrogen vacancy (NV) centers in diamond due to a noisy paramagnetic bath, with and without the presence of a rf field that couples levels of the ground electronic state manifold, using a simple quantum mechanical model that allows for analytical solutions. The model treats the NV three-level ground state system in the presence of fluctuating magnetic fields that arise from the environment, and that result in decoherence, dephasing and dissipation. We show that all 9 eigenmodes of the three-level system are coupled to each other due to interaction with the environment, and we discuss consequences for fitting experiments in which decoherence plays a role.

North Carolina in Ruins? The State Role in Financing Local Infrastructure
Creators: name: Heady, Kathleen M.
name: Drummond, William J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1983

description: Over the last two years there has risen a growing public concern about the state of the nation's infrastructure; that is, public facilities, highways, water supply, and wastewater treatment services. The genesis of this concern was the 1981 book, America in Ruins , by Pat Choate and Susan Walter. Choate and Walter argued that: "America's public facilities are wearing out faster than they are being replaced. Under the exigencies of tight budgets and inflation, the maintenance of public facilities essential to national economic renewal has been deferred. Replacement of obsolescent public works has been postponed. New construction has been cancelled... Without attention to deterioration of that infrastructure, economic renewal will be thwarted, if not impossible. We have no recourse but to face the complex task at hand of rebuilding our public facilities as an essential prerequisite to economic renewal." In North Carolina there is currently an estimated $3 billion backlog of needs to repair and replace obsolete, temporary, and deteriorating facilities in highways, sewer, and schools alone. The number of inhabitants in North Carolina is expected to increase by 17 to 25 percent by the year 2000, requiring the state's infrastructure to support between 900,000 and 1.4 million more people and up to one-half million more households. Employment is predicted to increase at approximately twice the rate of population growth. The level and location of major private sector capital and other investment decisions will likely be influenced by the quality of infrastructure available and whether or not a sound program for maintenance and expansion exists.

description: We introduce $ Λ(Φ) $-sets as generalizations of $ Λ(p) $-sets. These sets are defined in terms of Orlicz norms. We consider $Λ(Φ)$-sets when the Matuszewska-Orlicz index of $ Φ$ is larger than $ 2 $. When $S$ is a $Λ(Φ)$-set, we establish an estimate of the size of $ S \cap [-N,N] $ where $ N \in \mathbb{N} $. Next, we construct a $ Λ(Φ_1)$-set which is not a $ Λ(Φ_2)$-set for any $ Φ_2 $ such that $ \sup_{u \geq 1} Φ_2(u) / Φ_1(u) = \infty $ by using a probabilistic method. With an additional assumption about a subset $E$ of $\mathbb{Z}$, we can construct such a $Λ(Φ_1)$-set contained in $E$. These statements extend known results on the structure of $ Λ(p) $-sets to $Λ(Φ)$-sets.

description: This paper investigates the recent local currency initiatives inSwitzerland. These currencies are considered by their founders as atool for a necessary socioecological transition. The study mobilizesthe concept of grassroots social innovation and considers alternativecurrency clusters as a niche within the multi-level perspective ofsustainability transitions. To challenge the dominant monetary regime,a local currency niche must acquire a certain strength which can beexpressed in diffusion dynamics of four types: replication, scalingup, translation and innovative scope. A framework of these nichedynamics is used to analyze the emergence and diffusion of eightassociative local currency schemes. Data for this multiple case studywere collected via interviews, documentation and observation. Resultsshow that the local currencies in Switzerland were createdindependently by small groups of people active in the ecologicaltransition movement and the social and solidarity economy. Foundersexchange among each other in a loose network, and more experiencedactors support new projects with practical advice. In terms ofbusiness members and regular individual users, the currencyassociations have difficulties to reach a critical mass. What is more,support from public entities and more established actors is ratherlukewarm. Despite collective efforts and a lot of enthusiasm, theinfluence of the currency niche remains therefore limited.

description: Active galactic nuclei (AGN) show evidence for reprocessing gas, outflowing from the accreting black hole. The combined effects of absorption and scattering from the circumnuclear material likely explains the `hard excess' of X-ray emission above 20 keV, compared with extrapolation of spectra from lower X-ray energies. In a recent {\it Suzaku} study, we established the ubiquitous hard excess in hard X-ray-selected, radio-quiet type\,1 AGNs to be consistent with reprocessing of the X-ray continuum an ensemble of clouds, located tens to hundreds of gravitational radii from the nuclear black hole. Here we add hard X-ray-selected, type\,2 AGN to extend our original study and show that the gross X-ray spectral properties of the entire local population of radio quiet AGN may be described by a simple unified scheme. We find a broad, continuous distribution of spectral hardness ratio and Fe\,K$α$ equivalent width across all AGN types, which can be reproduced by varying the observer's sightline through a single, simple model cloud ensemble, provided the radiative transfer through the model cloud distribution includes not only photoelectric absorption but also 3D Compton scattering. Variation in other parameters of the cloud distribution, such as column density or ionisation, should be expected between AGN, but such variation is not required to explain the gross X-ray spectral properties.

description: Safety architectures play a crucial role in the safety assurance of automated driving vehicles (ADVs). They can be used as safety envelopes of black-box ADV controllers, and for graceful degradation from one ODD to another. Building on our previous work on the formalization of responsibility-sensitive safety (RSS), we introduce a novel program logic that accommodates assume-guarantee reasoning and fallback-like constructs. This allows us to formally define and prove the safety of existing and novel safety architectures. We apply the logic to a pull over scenario and experimentally evaluate the resulting safety architecture.

An Electric Southeast: Implications for Water Resource Planning
Creators: name: Dingfelder, Jackie

description: Growth in population, production, and income in the Southeastern U.S. is directly translated into growth in energy consumption. As a result, the environmental effects of fuel extraction, its conversion into other forms of energy, and the distribution and utilization of those forms has increased. Among the many dimensions of energy envivonmental linkages in the Southeast that must be explored is the relationship between electrical power production and the quantity and quality of the water resources. Presented here are two aspects of water use and energy. One is an overall view of energy consumption and the implications for water resource planning in the Southeast. The other specifically addresses the potential for the increased use of hydroelectric power at a small scale in North Carolina. Both present relevant information for the water resource planner.
Distinguishing Natural and Computer-Generated Images using Multi-Colorspace fused EfficientNet

description: The problem of distinguishing natural images from photo-realistic computer-generated ones either addresses natural images versus computer graphics or natural images versus GAN images, at a time. But in a real-world image forensic scenario, it is highly essential to consider all categories of image generation, since in most cases image generation is unknown. We, for the first time, to our best knowledge, approach the problem of distinguishing natural images from photo-realistic computer-generated images as a three-class classification task classifying natural, computer graphics, and GAN images. For the task, we propose a Multi-Colorspace fused EfficientNet model by parallelly fusing three EfficientNet networks that follow transfer learning methodology where each network operates in different colorspaces, RGB, LCH, and HSV, chosen after analyzing the efficacy of various colorspace transformations in this image forensics problem. Our model outperforms the baselines in terms of accuracy, robustness towards post-processing, and generalizability towards other datasets. We conduct psychophysics experiments to understand how accurately humans can distinguish natural, computer graphics, and GAN images where we could observe that humans find difficulty in classifying these images, particularly the computer-generated images, indicating the necessity of computational algorithms for the task. We also analyze the behavior of our model through visual explanations to understand salient regions that contribute to the model's decision making and compare with manual explanations provided by human participants in the form of region markings, where we could observe similarities in both the explanations indicating the powerful nature of our model to take the decisions meaningfully.
