description: The majority of electronic communication today happens either via email or chat. Thanks to the use of standardised protocols electronic mail (SMTP, IMAP, POP3) and instant chat (XMPP, IRC) servers can be deployed in a decentralised but interoperable fashion. These protocols can be secured by providing encryption with the use of TLS---directly or via the STARTTLS extension---and leverage X.509 PKIs or ad hoc methods to authenticate communication peers. However, many combination of these mechanisms lead to insecure deployments. We present the largest study to date that investigates the security of the email and chat infrastructures. We used active Internet-wide scans to determine the amount of secure service deployments, and passive monitoring to investigate if user agents actually use this opportunity to secure their communications. We addressed both the client-to-server interactions as well as server-to-server forwarding mechanisms that these protocols offer, and the use of encryption and authentication methods in the process. Our findings shed light on an insofar unexplored area of the Internet. The truly frightening result is that most of our communication is poorly secured in transit.

description: Studying the function of proteins is important for understanding the molecular mechanisms of life. The number of publicly available protein structures has increasingly become extremely large. Still, the determination of the function of a protein structure remains a difficult, costly, and time consuming task. The difficulties are often due to the essential role of spatial and topological structures in the determination of protein functions in living cells. In this paper, we propose ProtNN, a novel approach for protein function prediction. Given an unannotated protein structure and a set of annotated proteins, ProtNN finds the nearest neighbor annotated structures based on protein-graph pairwise similarities. Given a query protein, ProtNN finds the nearest neighbor reference proteins based on a graph representation model and a pairwise similarity between vector embedding of both query and reference protein-graphs in structural and topological spaces. ProtNN assigns to the query protein the function with the highest number of votes across the set of k nearest neighbor reference proteins, where k is a user-defined parameter. Experimental evaluation demonstrates that ProtNN is able to accurately classify several datasets in an extremely fast runtime compared to state-of-the-art approaches. We further show that ProtNN is able to scale up to a whole PDB dataset in a single-process mode with no parallelization, with a gain of thousands order of magnitude of runtime compared to state-of-the-art approaches.

description: We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system. In particular, we show how non-vanishing discord implies that the corresponding partition function does not factorize, both for generic pure states and the thermofield double state as a state with a known geometric dual in light of the AdS/CFT correspondence. Via this analysis, we give a novel interpretation to the thermomixed double state as the best purely classical approximation of the Einstein-Rosen bridge. We connect the non-vanishing of GQD with the existence of wormhole microstates.

description: We derive expressions for the expectation values of the local energy and the local power transferred by an external electrical field to a many-particle system of interacting spinless electrons. In analogy with the definition of the (local) presence and current probability densities, we construct a local energy operator such that the time-rate of change of its expectation value provides information on the spatial distribution of power. Results are presented as functions of an arbitrarily small volume $Ω$, and physical insights are discussed by means of the quantum hydrodynamical representation of the wavefunction, which is proven to allow for a clear-cut separation into contributions with and without classical correspondence. Quantum features of the local power are mainly manifested through the presence of non-local sources/sinks of power and through the action of forces with no classical counterpart. Many-particle classical-like effects arise in the form of current-force correlations and through the inflow/outflow of energy across the boundaries of the volume $Ω$. Interestingly, such intriguing features are only reflected in the expression for the local power when the volume $Ω$ is finite. Otherwise, for closed systems with $Ω\to \infty$, we recover a classical-like single-particle expression.

Resources to Recover: A Nonprofit Labor Market Intermediary for Rural North Carolina
Creators: name: Freyer, Allan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: On July 31, 2003, the Pillowtex plant in Kannapolis, NC closed its doors, laying off over 4,000 workers. The notion of the "economic disaster" was born, and in recent years has come to be defined as occurring when a significant proportion of the community's workforce is laid off through no fault of the workers, generating a high unemployment rate, a significant loss of local revenue, and emergency service and workforce development needs that overwhelm local resources. Because these disasters are not confined to Kannapolis, but instead continue to affect many rural communities throughout North Carolina, key stakeholders in the State's economic development agencies proposed an Action Agenda of policies and programs designed to help these communities and the dislocated workers who live in them successfully respond to the broad array of challenges presented by these economic disasters. As part of this agenda, two key policy documents recommended that policy makers develop an effective, collaborative response to economic disasters that involved the local voluntary non-profit sector, and specifically suggested the use of North Carolina Voluntary Organizations Active in Disasters (NC VOAD)- a natural disaster response organization - as a model for developing this program. The NC Rural Economic Development Center was tasked with developing this "economic VOAD" for North Carolina. Based in large part on research and program development conducted on behalf of the Rural Center, this Master's Project seeks to fulfill the policy recommendations laid out in the Action Agenda to develop a nonprofit response program for economic disasters. Specifically, this paper articulates a role for nonprofits as labor market intermediaries that can help connect dislocated workers to the state's workforce development system through the use of networking and "conversational space" for coordination and strategic planning in the aftermath of these disasters. As the original economic disaster, the Pillowtex example is used as a touchstone to examine the broader causes and consequences of these disasters and as a model for nonprofit intermediaries. Placed within a broader historical, theoretical, and policy context, the result is a proposed policy tool known as Resources to Recover (R2R).

description: In this paper, we study the rare radiative processes $B_c\to D_{sJ} ^{(*)}γ$ within the Standard Model, where $D_{sJ}^{(*)}$ stands for the meson $D_s^*$,~$D_{s1}(2460,2536)$ or ~$D_{s2}^*(2573)$. During the investigations, we consider the contributions from the penguin, annihilation, color-suppressed and color-favored cascade diagrams. Our results show that: 1) the penguin and annihilation contributions are dominant in the branching fractions; 2) for the processes $B_c\to D_s^{*}γ$ and $B_c\to D_{s1}(2460,2536)γ$, the effects from the color-suppressed and color-favored cascade diagrams are un-negligible.

description: Phasons are collective low-energy modes that appear in disparate condensed matter systems such as quasicrystals, incommensurate structures, fluctuating charge density waves, and Moiré superlattices. They share several similarities with acoustic phonon modes, but they are not protected by any exact translational symmetry. As a consequence, they are subject to a wavevector independent damping, and they develop a finite pinning frequency, which destroy their acoustic linearly propagating dispersion. Under a few and simple well-motivated assumptions, we compute the phason density of states, and we derive the phason heat capacity as a function of the temperature. Finally, imagining a hypothetical s-wave pairing channel with electrons, we compute the critical temperature $T_c$ of the corresponding superconducting state as a function of phason damping using the Eliashberg formalism. We find that for large phason damping, the heat capacity is linear in temperature, showing a distinctive glass-like behavior. Additionally, we observe that the phason damping can strongly enhance the effective Eliashberg coupling, and we reveal a sharp non-monotonic dependence of the superconducting temperature $T_c$ on the phason damping, with a maximum located at the underdamped to overdamped crossover scale. Our simple computations confirm the potential role of overdamped modes in explaining the glassy properties of incommensurate structures, but also in possibly inducing strongly-coupled superconductivity therein, and enhancing the corresponding $T_c$.

Promoting help-seeking behaviour among medical trainees - a scoping review
Creators: name: Sun, Si
Publisher: name: Open Science Framework

Subjects: subject: Medicine and Health Sciences

description: Over the past decade, there has been increasing interest and awareness that there is a substantial proportion of medical students and residents who suffer from the impacts of mental health concerns such as addiction and suicidal ideation, and that only a small proportion of them seek help. Though there exist numerous publications calling for action and recommending interventions at various levels to promote medical trainee help-seeking, there is a lack of understanding of what specific interventions have been implemented, what were some of the barriers to implementing such interventions, and whether or not they were effective. Without this knowledge, it is difficult to know what works, how to design an effective intervention to support our medical trainees, and what our future directions need to be. In this scoping review, we aim to synthesize knowledge about interventions that have been tried to promote help-seeking behaviour for mental health issues among medical trainees.

description: The Feynman--Hellmann approach to computing matrix elements in lattice QCD by first adding a perturbing operator to the action is described using the transition matrix and the Dyson expansion formalism. This perturbs the energies in the two-point baryon correlation function, from which the matrix element can be obtained. In particular at leading order in the perturbation we need to diagonalise a matrix of near-degenerate energies. While the method is general for all hadrons, we apply it here to a study of a Sigma to Nucleon baryon transition vector matrix element.

Ten years of public-private water supply provision in Jakarta, Indonesia: why private water supply management in Jakarta failed to achieve the expected improvements in efficiency and effectiveness of water delivery
Creators: name: Kartikawening Miller, Dyah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: In 1998, a 25-year concession contract on the water supply provision for DKI Jakarta was signed between Perusahaan Air Minum Jakarta Raya (PAM Jaya) and Thames Water Overseas, with local partner: PT. Kekar Pola Airindo, on the east side, and Suez Lyonnaise des Eaux with local partner: PT. Garuda Dipta Semesta on the west side. The Ciliwung River divided Jakarta into two areas for the concessionaires (Lanti, 2006). The contract was signed and became effective in February 1998. The fall of the Suharto administration delayed the implementation of the contract. Later in 1998, new negotiations were started to move the contract forward. These negotiations resulted in a Restated Cooperation Agreement that was signed in October 2001. The Jakarta concession contract was among the biggest contracts executed in less developed countries. It was comparable in size to contracts in Manila, Philippines, and Buenos Aires, Argentina. The service coverage expanded from 41% in 1995 to 62% in 2009, while many technical targets of the concession contracts were not achieved as expected. The private sectors have been criticized for only concentrating the expansion connections in the wealthier areas of the city (Bakker, 2004, p. 115), although the issue of connections, which related to other issues such as land and settlement issues with the local government of Jakarta in slum areas in Jakarta, existed prior to the concession contract. This paper focuses on public private partnership of drinking water supply in Jakarta. It aims to assess whether public private partnership in drinking water in an urban area in developing countries has succeeded or failed to achieve the expected improvements in efficiency and effectiveness of water delivery. To better address the efficiency and effectiveness expected, it is necessary to examine the progress of the public private partnership from the origin of the contract to 2009. 7 Further, the paper discusses conflicts in the system among the institutions and stakeholders involved and recommendations to overcome these conflicts. To understand the conflicts in the partnership, it is important to understand the perceptions of the stakeholders in drinking water supply in Jakarta.

description: Recently, the Fermi-LAT gamma-ray satellite has detected six Giant Molecular Clouds (GMCs) located in the Gould Belt and the Aquila Rift regions. In half of these objects (Taurus, Orion A, Orion B), the observed gamma-ray spectrum can be explained using the Galactic diffused Cosmic Ray (CR) interactions with the gas environments. In the remaining three GMCs (Rho Oph, Aquila Rift, Cepheus), the origin of the gamma-ray spectrum is still not well established. We use the GEometry ANd Tracking (GEANT4) simulation framework in order to simulate gamma-ray emission due to CR/GMC interaction in these three objects, taking into account the gas density distribution inside the GMCs. We find that propagation of diffused Galactic CRs inside these GMCs can explain the Fermi-LAT detected gamma-ray spectra. Further, our estimated TeV-PeV fluxes are consistent with the HAWC upper limits, available for the Aquila Rift GMC. As last step, we compute the total neutrino flux estimated for these GMCs and compare it with the IceCube detection sensitivity.

An almost convincing scheme for discriminating the preparation basis of quantum ensemble and why it will not work

description: Mixed states of a quantum system, represented by density operators, can be decomposed as a statistical mixture of pure states in a number of ways where each decomposition can be viewed as a different preparation recipe. However the fact that the density matrix contains full information about the ensemble makes it impossible to estimate the preparation basis for the quantum system. Here we present a measurement scheme to (seemingly) improve the performance of unsharp measurements. We argue that in some situations this scheme is capable of providing statistics from a single copy of the quantum system, thus making it possible to perform state tomography from a single copy. One of the byproduct of the scheme is a way to distinguish between different preparation methods used to prepare the state of the quantum system. However, our numerical simulations disagree with our intuitive predictions. We show that a counter-intuitive property of a biased classical random walk is responsible for the proposed mechanism not working.

Urbanization effects on the coast: a study of land cover change around Chennai, India
Creators: name: Eshleman, Anne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: The protection of natural lands is a continual struggle around the world as development pressure continues to push land conversion. Systems to prevent such conversion are in place or in process in many areas, protecting lands deemed important for any of several factors such as the ecological, aesthetic, or functional services provided by such lands. In many countries, these systems include numerous environmental groups purchasing land or development rights; local, state, and federal governmental programs managing development with endless combinations of growth management tools; and most importantly, a comprehensive and accessible database of temporal land cover data covering the entire country. This data allows the first two groups to monitor land cover change in order to identify lands and ecosystems in need of protection, and then effectively implement programs to achieve this protection. In rapidly urbanizing countries, conversely, such data is not processed and distributed to the same degree. India, in particular, has experienced rapid urbanization since the mid 1990's, but the impacts of this urbanization on natural lands and the ecosystem services they provide have not been studied sufficiently. Wetlands in India are especially vulnerable to the expansion of urban areas, and an understanding of the impacts of the last two decades of growth on wetlands is necessary to determine how these ecosystems can or should be protected over the next several decades. This study examines land cover change over time in the area around one coastal city, Chennai, in order to demonstrate a method for identifying the impacts of its development on nearby wetlands. I find that water bodies and wetlands around Chennai increased over a fifteen-year period as the city expanded. This increase is characterized by greater fragmentation during Chennai's summer season, but greater aggregation of hydric areas during the monsoon season. These results have implications for the water quality of Chennai's water supply and the ecological effects of the stormwater runoff produced from its development.

description: We present simultaneous XMM-Newton and NuSTAR observations spanning 3-78 keV of the nearest radio galaxy, Centaurus A (Cen A). The accretion geometry around the central engine in Cen A is still debated, and we investigate possible configurations using detailed X-ray spectral modeling. NuSTAR imaged the central region of Cen A with sub-arcminute resolution at X-ray energies above 10 keV for the first time, but finds no evidence for an extended source or other off-nuclear point-sources. The XMM-Newton and NuSTAR spectra agree well and can be described with an absorbed power-law with a photon index Γ = 1.815 +/- 0.005 and a fluorescent Fe Kα line in good agreement with literature values. The spectrum does not require a high-energy exponential rollover, with a constraint of E_fold > 1 MeV. A thermal Comptonization continuum describes the data well, with parameters that agree with values measured by INTEGRAL, in particular an electron temperature kTe between ~100-300 keV, seed photon input temperatures between 5-50 eV. We do not find evidence for reflection or a broad iron line and put stringent upper limits of R < 0.01 on the reflection fraction and accretion disk illumination. We use archival Chandra data to estimate the contribution from diffuse emission, extra-nuclear point-sources, and the outer X-ray jet to the observed NuSTAR and XMM-Newton X-ray spectra and find the contribution to be negligible. We discuss different scenarios for the physical origin of the observed hard X-ray spectrum, and conclude that the inner disk is replaced by an advection-dominated accretion flow or that the X-rays are dominated by synchrotron self-Compton emission from the inner regions of the radio jet or a combination thereof.

description: In this work, we consider the quantum-corrected Reissner-Nordström black hole surrounded by quintessence matter and examine its thermodynamics and shadow. To this end, we handle the quantum-corrected metric of the black hole, which is given by Wu and Lui in 2022, and couple the quintessence matter field effects to the lapse function. Then, we obtain the mass, Hawking temperature, specific heat, and equation of state functions. In all these functions, we discuss two cases in which the quantum corrections are greater or smaller than the quintessence matter effects. We observe that within these two scenarios, the black hole has different characteristic thermal behaviors. Moreover, we find that the quintessence matter plays an important role in leading to a black hole remnant. Finally, we investigate the black hole shadow by Carter's approach. We find that quintessence matter and quantum corrections modify the shadow of the black hole.

description: A comprehensive characterization of the detection efficiency of nine of the major asteroid surveys that have been active over the past two decades is presented. The detection efficiency is estimated on a nightly basis by comparing the detected asteroids with the complete catalog of known asteroids propagated to the same observing epoch. Results include a nightly estimate of the detection efficiency curves as a function of apparent magnitude and apparent velocity of the asteroids, as well as a cumulative analysis to estimate the overall performance of each survey. The limiting magnitude distribution is estimated for each survey, and it is then modeled as a function of telescope aperture to obtain an estimate over a wide range of apertures.

description: Among several models for microswimmers, the three-sphere microswimmer proposed by Najafi and Golestanian captures the essential mechanism for the locomotion of a microswimmer in a viscous fluid. Owing to its simplicity and flexibility, the original three-sphere model has been extended and generalized in various ways to discuss new swimming mechanisms of microswimmers. We shall provide a systematic and concise review of the various extensions of the three-sphere microswimmers that have been developed by the present authors. In particular, we shall discuss the following seven cases; elastic, thermal, odd, autonomous three-sphere microswimmers; two interacting ones; and those in viscoelastic and structured fluids. The well-known Purcell's scallop theorem can be generalized for stochastic three-sphere microswimmers and also for the locomotion in viscoelastic and structured fluids.

description: Previously predicted by the $S$-matrix bootstrap of the excitations over the GKP quantum vacuum, the appearance of a new particle at strong coupling -- formed by one fermion and one anti-fermion -- is here confirmed: this two-dimensional meson shows up, along with its infinite tower of bound states, while analysing the fermionic contributions to the Operator Product Expansion (collinear regime) of the Wilson null polygon loop. Moreover, its existence, free \footnote{This term is used here as opposite to bound, thus as {\it unbound}.} and bound, turns out to be a powerful idea in re-summing all the contributions (at large coupling) for a general $n$-gon ($n\geq 6$) to a Thermodynamic Bethe Ansatz, which is proven to be equivalent to the known one and suggests new structures for a special $Y$-system.

Creating Successful Social Purpose Enterprises
Creators: name: Binder, Ruth Ann

description: Nonprofit organizations are seeking innovative strategies for producing income while furthering their social missions. This is in part because of recent changes in government and foundation funding, and in part because of the need to address social problems in a different way. One of the strategies created by nonprofits is the social purpose enterprise (SPE). SPEs are businesses that are owned and operated by nonprofit organizations for the purposes of generating revenue and employing those whom they are trying to help. This paper adds to the growing knowledge about SPEs by identifying factors that contribute to their success. Nonprofits that currently operate SPEs, and foundation and nonprofit staff that are interested in business development will find this paper to be useful in guiding their practice and informing their funding decisions. The research is based on a literature review and on interviews with practitioners and consultants who work with SPEs. Three case studies of nonprofits that have run or are currently running commercial ventures are examined. The study identifies four main factors that account of the success of SPEs. They are: Nonprofits that run SPEs need staff who are skilled at managing businesses and working with employees who have little or no work experience. Those nonprofit organizations must have business plans that address the needs of the programs' clients and have specific social and employment goals. Nonprofits need sustained, and preferably unrestricted funding to hire qualified staff and strengthen their infrastructure. They also need financial systems that can track social programs and commercial activities.

description: The increasing digitalization of power grids and especially the shift towards IP-based communication drastically increase the susceptibility to cyberattacks, potentially leading to blackouts and physical damage. Understanding the involved risks, the interplay of communication and physical assets, and the effects of cyberattacks are paramount for the uninterrupted operation of this critical infrastructure. However, as the impact of cyberattacks cannot be researched in real-world power grids, current efforts tend to focus on analyzing isolated aspects at small scales, often covering only either physical or communication assets. To fill this gap, we present WATTSON, a comprehensive research environment that facilitates reproducing, implementing, and analyzing cyberattacks against power grids and, in particular, their impact on both communication and physical processes. We validate WATTSON's accuracy against a physical testbed and show its scalability to realistic power grid sizes. We then perform authentic cyberattacks, such as Industroyer, within the environment and study their impact on the power grid's energy and communication side. Besides known vulnerabilities, our results reveal the ripple effects of susceptible communication on complex cyber-physical processes and thus lay the foundation for effective countermeasures.

Absence of inhomogeneous chiral phases in 2+1-dimensional four-fermion and Yukawa models

description: We show the absence of an instability of homogeneous (chiral) condensates against spatially inhomogeneous perturbations for various 2+1-dimensional four-fermion and Yukawa models. All models are studied at non-zero baryon chemical potential, while some of them are also subjected to chiral and isospin chemical potential. The considered theories contain up to 16 Lorentz-(pseudo)scalar fermionic interaction channels. We prove the stability of homogeneous condensates by analyzing the bosonic two-point function, which can be expressed in a purely analytical form at zero temperature. Our analysis is presented in a general manner for all of the different discussed models. We argue that the absence of an inhomogeneous chiral phase (where the chiral condensate is spatially non-uniform) follows from this lack of instability. Furthermore, the existence of a moat regime, where the bosonic wave function renormalization is negative, in these models is ruled out.

description: The reionization of intergalactic hydrogen has received intense theoretical scrutiny over the past two decades. Here, we approach the process formally as a percolation process and phase transition. Using semi-numeric simulations, we demonstrate that an infinitely-large ionized region abruptly appears at an ionized fraction of ~0.1 and quickly grows to encompass most of the ionized gas: by an ionized fraction of 0.3, nearly ninety percent of the ionized material is part of this region. Throughout most of reionization, nearly all of the intergalactic medium is divided into just two regions, one ionized and one neutral, and both infinite in extent. We also show that the discrete ionized regions that exist before and near this transition point follow a near-power law distribution in volume, with equal contributions to the total filling factor per logarithmic interval in size up to a sharp cutoff in volume. These qualities are generic to percolation processes, with the detailed behavior a result of long-range correlations in the underlying density field. These insights will be crucial to understanding the distribution of ionized and neutral gas during reionization and provide precise meaning to the intuitive description of reionization as an "overlap" process.

Regional Visioning Initiatives: Process and Implementation
Creators: name: Barth, Pamela
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This paper is part of a larger effort by the USEPA to create a cost/benefit analysis of regional visioning initiatives. While the costs and benefits of various initiatives will not be analyzed here, this paper provides background on regions and on visioning initiatives and their components, and it also contains two case studies of regional visioning initiatives that occurred in the 1990s. This paper will focus on regions that are based on metropolitan areas; it will address regional, rather than community-based, visioning initiatives; and it will investigate those initiatives that are motivated by land use, transportation, and environmental concerns. Because the visioning initiatives discussed in this paper originated in the mid- to late-1990s, effects of these initiatives cannot be discussed with any validity at this time. What will be examined is the robustness of the process, the resulting action plans, and the implementation efforts to this date.
