description: We consider the ferromagnetic nearest-neighbor Ising model on regular trees (Bethe lattice), which is well-known to undergo a phase transition in the absence of an external magnetic field. The behavior of the model at critical temperature can be described in terms of various critical exponents; one of them is the critical 1-arm exponent $ρ$, which characterizes the rate of decay of the (root) magnetization. The crucial quantity we analyze in this work is the thermal expectation of the root spin on a finite subtree, where the expected value is taken with respect to a probability measure related to the corresponding finite-volume Hamiltonian with a fixed boundary condition. The spontaneous magnetization, which is the limit of this thermal expectation in the distance between the root and the boundary (i.e. in the height of the subtree), is known to vanish at criticality. We are interested in a quantitative analysis of the rate of this convergence in terms of the critical 1-arm exponent $ρ$. Therefore, we rigorously prove that $\langleσ_0\rangle^+_n$, the thermal expectation of the root spin at the critical temperature and in the presence of the positive boundary condition, decays as $\langleσ_0\rangle^+_n\approx n^{-1/2}$ (in a rather sharp sense), where $n$ is the height of the tree. This establishes the 1-arm critical exponent for the Ising model on regular trees ($ρ=1/2$).

description: Storage-based intrusion detection allows storage systems to watch for data modifications characteristic of system in-trusions. This enables storage systems to spot several common intruder actions, such as adding backdoors, inserting Trojan horses, and tampering with audit logs. Further, an intrusion detection system (IDS) embedded in a storage device continues to operate even after client systems are compromised. This paper describes a number of specific warning signs visible at the storage interface. Examination of 18 real intrusion tools reveals that most (15) can be detected based on their changes to stored files. We describe and evaluate a prototype storage IDS, embedded in an NFS server, to demonstrate both feasibility and efficiency of storage-based intrusion detection. In particular, both the performance overhead and memory required (152 KB for 4730 rules) are minimal.

description: We evaluate the quasinormal modes of massless Dirac perturbation in a Schwarzschild black hole surrounded by the free static spherically symmetric quintessence by using the third-order WKB approximation. The result shows that due to the presence of quintessence, the massless field damps more slowly. The real part of the quasinormal modes increases and the the absolute value of the imaginary part increases when the state parameter $w_q$ increases. In other words, the massless Dirac field decays more rapidly for the larger $w_q$. And the peak value of potential barrier gets higher as $|k|$ increases and the location of peak moves along the right for fixed $w_q$.

Efficient linear scaling method for computing the thermal conductivity of disordered materials

description: An efficient order$-N$ real-space Kubo approach is developed for the calculation of the thermal conductivity of complex disordered materials. The method, which is based on the Chebyshev polynomial expansion of the time evolution operator and the Lanczos tridiagonalization scheme, efficiently treats the propagation of phonon wave-packets in real-space and the phonon diffusion coefficients. The mean free paths and the thermal conductance can be determined from the diffusion coefficients. These quantities can be extracted simultaneously for all frequencies, which is another advantage in comparison with the Green's function based approaches. Additionally, multiple scattering phenomena can be followed through the time dependence of the diffusion coefficient deep into the diffusive regime, and the onset of weak or strong phonon localization could possibly be revealed at low temperatures for thermal insulators. The accuracy of our computational scheme is demonstrated by comparing the calculated phonon mean free paths in isotope-disordered carbon nanotubes with Landauer simulations and analytical results. Then, the upscalibility of the method is illustrated by exploring the phonon mean free paths and the thermal conductance features of edge disordered graphene nanoribbons having widths of $\sim$20 nanometers and lengths as long as a micrometer, which are beyond the reach of other numerical techniques. It is shown that, the phonon mean free paths of armchair nanoribbons are smaller than those of zigzag nanoribbons for the frequency range which dominate the thermal conductance at low temperatures. This computational strategy is applicable to higher dimensional systems, as well as to a wide range of materials.

description: Storage device performance prediction is a key element of self-managed storage systems. This work explores the application of a machine learning tool, CART models, to storage device modeling. Our approach predicts a device’s performance as a function of input workloads, requiring no knowledge of the device internals. We propose two uses of CART models: one that predicts per-request response times (and then derives aggregate values) and one that predicts aggregate values directly from workload characteristics. After being trained on the device in question, both provide accurate black-box models across a range of test traces from real environments. Experiments show that these models predict the average and 90th percentile response time with an relative error as low as 19% when the training workloads are similar to the testing workloads and a good interpolation across different workloads.

description: We present photometry, spectra, and spectropolarimetry of supernova (SN) 2012ab, mostly obtained over the course of $\sim 300$ days after discovery. SN 2012ab was a Type IIn (SN IIn) event discovered near the nucleus of spiral galaxy 2MASXJ12224762+0536247. While its light curve resembles that of SN 1998S, its spectral evolution does not. We see indications of CSM interaction in the strong intermediate-width emission features, the high luminosity (peak at absolute magnitude $M=-19.5$), and the lack of broad absorption features in the spectrum. The H$α$ emission undergoes a peculiar transition. At early times it shows a broad blue emission wing out to $-14{,}000$ km $\mathrm{s^{-1}}$ and a truncated red wing. Then at late times ($>$ 100$\,$days) it shows a truncated blue wing and a very broad red emission wing out to roughly $+20{,}000$ km $\mathrm{s^{-1}}$. This late-time broad red wing probably arises in the reverse shock. Spectra also show an asymmetric intermediate-width H$α$ component with stronger emission on the red side at late times. The evolution of the asymmetric profiles requires a density structure in the distant CSM that is highly aspherical. Our spectropolarimetric data also suggest asphericity with a strong continuum polarization of $\sim 1-3$% and depolarization in the H$α$ line, indicating asphericity in the CSM at a level comparable to that in other SNe IIn. We estimate a mass-loss rate of $\dot{M} = 0.050\, {\rm M}_{\odot}\,\mathrm{yr^{-1}}$ for $v_{\rm pre} = 100$$\,$km$\,$$\mathrm{s^{-1}}$ extending back at least 75$\,$yr prior to the SN. The strong departure from axisymmetry in the CSM of SN 2012ab may suggest that the progenitor was an eccentric binary system undergoing eruptive mass loss.

description: We present a lattice study of up to N=20 unitary fermions confined to a harmonic trap. Our preliminary results show better than 1% agreement with high precision solutions to the many-body Schrodinger equation for up to N=6. We are able to make predictions for larger N which were inaccessible by the Hamiltonian approach due to computational limitations. Harmonic traps are used experimentally to study cold atoms tuned to a Feshbach resonance. We show that they also provide certain benefits to numerical studies of many-body correlators on the lattice. In particular, we anticipate that the methods described here could be used for studying nuclear physics.

description: Self-securing network interfaces (NIs) examine the packets that they move between network links and host software, looking for and potentially blocking malicious network activity. This paper describes self-securing network interfaces, their features, and examples of how these features allow administrators to more effectively spot and contain malicious network activity. We present a software architecture for self-securing NIs that separates scanning software into applications (called scanners) running on an NI kernel. The resulting scanner API simplifies the construction of scanning software and allows its powers to be contained even if it is subverted. We illustrate the potential via a prototype self-securing NI and two example scanners: one that identifies and blocks known e-mail viruses and one that identifies and inhibits rapidly-propagating worms like Code-Red.

description: We theoretically study the longitudinal relaxation of a nitrogen-vacancy (NV) center surrounded by a 13C nuclear spin bath in diamond. By incorporating electron spin in the cluster, we generalize the cluster-correlation expansion (CCE) to theoretically simulate the population dynamics of electron spin of NV center. By means of the generalized CCE, we numerically demonstrate the decay process of electronic state induced by cross relaxation at the ambient temperature. It is shown that the CCE method is not only capable of describing pure-dephasing effect at large-detuning regime, but it can also simulate the quantum dynamics of populations in the nearly-resonant regime.

description: This report is based on empirical research carried out as a part of the research task T4.5. The research utilises findings from the inventory of mountain value chains in Europe (T4.1) and the extended analysis of VC-A in reference regions (T4.2 -T4.5). Conceptualisation of the empirical study draws on the conceptual-analytical framework developed within the WP2 (Moretti et al. 2021).

The general objective of the study is to evaluate the vulnerability and resilience of the value chain assemblage to climate and other changes within the Mountain Reference Landscape (MRL) by assessing responses to drivers in the past and up to the present day. 

The structure of the report follows a similar logic. After introducing the main objectives (Chapter 2), key concepts implemented in the study (Chapter 3) and methods (Chapter 4), a detailed view of existing threats and their impacts (Chapter 5) is provided. This is followed by the overviewed resources for developing adaptive strategies (Chapter 6) and the possibilities of the actors to utilise them. Information about the vulnerability of mountain regions and their value chains is thereafter summarised (Chapter 7). At the end of the report, the ‘profiles’ of 23 reference regions are presented with respect to their specific threats, impacts and preconditions for building adaptive strategies (Chapter 8). Final conclusions of the study are presented in the last chapter (Chapter 9).

The empirical study enabled the most important threats to mountain value chains to be identified from the perspective of stakeholders. These threats include environmental, socioeconomic and political and institutional threats. All threats were evaluated and ranked by stakeholders with respect to their importance and existing adverse effects.

Participatory workshops with stakeholders in mountain regions enabled multiple preconditions to be identified for building an adaptive capacity for mitigating these adverse effects. All preconditions were classified according to their linkage to mountain value chains.

The report presents specific data about each of the MRL that include: a list of the most important threats, illustrative examples of the narrative of adverse effects and their impacts on value chains, preconditions for building the adaptive capacity and a short summary related to the overall vulnerability and resilience of the mountain reference region and the selected value chain.

description: This white paper describes a new project exploring the design and implementation of “self-* storage systems:” self-organizing, self-configuring, self-tuning, self-healing, self-managing systems of storage bricks. Borrowing organizational ideas from corporate structure and automation technologies from AI and control systems, we hope to dramatically reduce the administrative burden currently faced by data center administrators. Further, compositions of lower cost components can be utilized, with available resources collectively used to achieve high levels of reliability, availability, and performance.
Difference Tones in "Non-Pythagorean" Scales Based on Logarithms

description: In order to explore tonality outside of the `Pythagorean' paradigm of integer ratios, Robert Schneider introduced a musical scale based on the logarithm function. We seek to refine Schneider's scale so that the difference tones generated by different degrees of the scale are themselves octave equivalents of notes in the scale. In doing so, we prove that a scale which contains all its difference tones in this way must consist solely of integer ratios. With this in mind, we present some methods for producing logarithmic scales which contain many, but not all, of the difference tones they generate.

description: The vulnerability matrices developed for the 23 MRLs are the most comprehensive analysis of the vulnerability of land use systems in Europe's mountains to date. This work captures the perceptions of a large number of farmers, managers, extension agents and researchers on the importance of the drivers of change that determine the vulnerability of the systems, indicating that the drivers of change that most affect and will affect in the near future, as well as the resource base for the selected value chains, are specific to each MRL. However, it has been observed that the spatial information provided, as well as the indicators produced, are sometimes difficult to understand and interpret with the actors involved, which highlighted the importance of an adequate knowledge transfer adapted to the variability of the stakeholders. However, the methodology used has proven to provide more comprehensive, substantial, and contextualised knowledge, as well as fostering interaction and increased knowledge exchange between the actors involved.

The information processed and produced in this work provides a solid basis for assessing the challenges faced by the selected value chains in the near future in their respective MRLs, as well as assessing how changes in the value chain can affect, reinforce or minimise the effects of the identified drivers of change. As a follow-up to these results, and with the aim of improving the transfer of the knowledge generated, work is currently underway to develop and provide interactive visual tools - especially maps and indicators - that offer real information on assets, sustainability, and resilience, and that can contribute to the awareness of AKIS (Agricultural Knowledge and Information Systems), the VC actors, the civil society and the political actors in mountain areas. 

The main document includes the vulnerability matrix of the 23 MRLs and those vulnerability maps that could be calculated. In addition, a more detailed vulnerability analysis report has been included as Appendix for each MRL including information on the context, drivers and its components and the participatory analysis of the driver ranking, trends, sensitivity, and adaptive mechanisms.

Physical state condition in Quantum General Relativity as a consequence of BRST symmetry

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Quantization of systems with constraints can be carried on with several methods. In the Dirac formulation the classical generators of gauge transformations are required to annihilate physical quantum states to ensure their gauge invariance. Carrying on BRST symmetry it is possible to get a condition on physical states which, differently from the Dirac method, requires them to be invariant under the BRST transformation. Employing this method for the action of general relativity expressed in terms of the spin connection and tetrad fields with path integral methods, we construct the generator of BRST transformation associated with the underlying local Lorentz symmetry of the theory and write a physical state condition consequence of BRST invariance. We observe that this condition differs form the one obtained within Ashtekar's canonical formulation, showing how we recover the latter only by a suitable choice of the gauge fixing functionals. We finally discuss how it should be possible to obtain all the requested physical state conditions associated with all the underlying gauge symmetries of the classical theory using our approach.

description: Survivable storage system design has become a popular research topic. This paper tackles the difficult problem of reasoning about the engineering trade-offs inherent in data distribution scheme selection. The choice of an encoding algorithm and its parameters positions a system at a particular point in a complex trade-off space between performance, availability, and security. We demonstrate that no choice is right for all systems, and we present an approach to codifying and visualizing this trade-off space. Using this approach, we explore the sensitivity of the space to system characteristics, workload, and desired levels of security and availability. This research is part of the PASIS project at Carnegie Mellon University.

This work captures the perceptions of a large number of farmers, managers, extension agents and researchers on the importance of the drivers of change that determine the vulnerability of the systems, indicating that the drivers of change that most affect and will affect in the near future, as well as the resource base for the selected value chains, are specific to each MRL. However, it has been observed that the spatial information provided, as well as the indicators produced, are sometimes difficult to understand and interpret with the actors involved, which highlighted the importance of an adequate knowledge transfer adapted to the variability of the stakeholders. However, the methodology used has proven to provide more comprehensive, substantial, and contextualised knowledge, as well as fostering interaction and increased knowledge exchange between the actors involved.

The information processed and produced in this work provides a solid basis for assessing the challenges faced by the selected value chains in the near future in their respective MRLs, as well as assessing how changes in the value chain can affect, reinforce or minimise the effects of the identified drivers of change. As a follow-up to these results, and with the aim of improving the transfer of the knowledge generated, work is currently underway to develop and provide interactive visual tools - especially maps and indicators - that offer real information on assets, sustainability, and resilience, and that can contribute to the awareness of AKIS (Agricultural Knowledge and Information Systems), the VC actors, the civil society and the political actors in mountain areas. 

The main document includes the vulnerability matrix of the 23 MRLs and those vulnerability maps that could be calculated. In addition, a more detailed vulnerability analysis report has been included as Appendix for each MRL including information on the context, drivers and its components and the participatory analysis of the driver ranking, trends, sensitivity, and adaptive mechanisms.

description: An observational study was made of the newly identified cyanomethane radical CH2CN and the possibly related species CH3CN with the goals of elucidating the possible role of reactions of the type CnHm(+) + N in astrochemistry, and providing a possible test of Bates's models of dissociative electron recombination. A remarkably different abundance ratio CH2CN/CH3CN was found in TMC-1 and Sgr B2 which is deduced to be a result of the large difference in temperature of these objects. Studies of CH2CN and CH3CN in other sources, including two new detections of CH2CN, support this conclusion and are consistent with a monotonic increase in the CH2CN/CH3CN ratio with decreasing temperature over the range 10-120 K. This behavior may be explained by the destruction of CH2CN by reaction with O.

description: This paper describes the Open Access eXchange (OAeX) project, a pragmatic and comprehensive economic model and fundraising platform for open scholarship initiatives. OAeX connects bidders with funders at scale and right across the open scholarship spectrum through crowdfunding: financial expenditure is regulated by a market of freely competing providers and financial transactions and transparency are assured by a clearinghouse entity. Specifically, OAeX seeks to facilitate open access publishing without the barrier of article processing charges (APCs), as well as contribute to solving challenges of transparency and economic sustainability in open scholarship projects in the broader sense.
On sofic groups, Kaplansky's conjectures, and endomorphisms of pro-algebraic groups

description: Let $G$ be a group. Let $X$ be a connected algebraic group over an algebraically closed field $K$. Denote by $A=X(K)$ the set of $K$-points of $X$. We study a class of endomorphisms of pro-algebraic groups, namely algebraic group cellular automata over $(G,X,K)$. They are cellular automata $τ\colon A^G \to A^G$ whose local defining map is induced by a homomorphism of algebraic groups $X^M \to X$ where $M\subset G$ is a finite memory set of $τ$. Our first result is that when $G$ is sofic, such an algebraic group cellular automaton $τ$ is invertible whenever it is injective and $\text{char}(K)=0$. As an application, we prove that if $G$ is sofic and the group $X$ is commutative then the group ring $R[G]$, where $R=\text{End}(X)$ is the endomorphism ring of $X$, is stably finite. When $G$ is amenable, we show that an algebraic group cellular automaton $τ$ is surjective if and only if it satisfies a weak form of pre-injectivity called $(\bullet)$-pre-injectivity. This yields an analogue of the classical Moore-Myhill Garden of Eden theorem. We also introduce the near ring $R(K,G)$ which is $K[X_g: g \in G]$ as an additive group but the multiplication is induced by the group law of $G$. The near ring $R(K,G)$ contains naturally the group ring $K[G]$ and we extend Kaplansky's conjectures to this new setting. Among other results, we prove that when $G$ is an orderable group, then all one-sided invertible elements of $R(K,G)$ are trivial, i.e., of the form $aX_g+b$ for some $g\in G$, $a\in K^*$, $b\in K$. This allows us to show that when $G$ is locally residually finite and orderable (e.g. $\mathbb{Z}^d$ or a free group), and $\text{char}(K)=0$, all injective algebraic cellular automata $τ\colon \mathbb{C}^G \to \mathbb{C}^G$ are of the form $τ(x)(h)= a x(g^{-1}h) +b$ for all $x\in \mathbb{C}^G, h \in G$ for some $g\in G$, $a\in \mathbb{C}^*$, $b\in \mathbb{C}$.

description: Thermal rectification is of importance not only for fundamental physics, but also for potential applications in thermal manipulations and thermal management. However, thermal rectification effect usually decays rapidly with system size. Here, we show that a mass-graded system, with two diffusive leads separated by a ballistic spacer, can exhibit large thermal rectification effect, with the rectification factor independent of system size. The underlying mechanism is explained in terms of the effective size-independent thermal gradient and the match/mismatch of the phonon bands. We also show the robustness of the thermal diode upon variation of the model's parameters. Our finding suggests a promising way for designing realistic efficient thermal diodes.

description: The role of local fields in the optical response of silicon nanocrystals is analyzed using a tight binding approach. Our calculations show that, at variance with bulk silicon, local field effects dramatically modify the silicon nanocrystal optical response. An explanation is given in terms of surface electronic polarization and confirmed by the fair agreement between the tight binding results and that of a classical dielectric model. From such a comparison, it emerges that the classical model works not only for large but also for very small nanocrystals. Moreover, the dependence on size of the optical response is discussed, in particular treating the limit of large size nanocrystals.

description: This technical report contains seven final project reports contributed by sixteen participants in CMU's Systems Software introductory graduate course offered by Professor Garth Gibson. This course studies the design and analysis of operating systems and distributed systems through a series of background lectures, paper readings, guest lectures and group projects. Projects were done in groups of two or three, required some kind of implementation and evaluation pertaining to the classroom material, but with the topic of these projects left up to each group. Final reports were held to the standard of a systems conference paper submission; a standard well met by the majority of the completed projects, albeit with less thoroughness in the related work category than is expected in most conferences. The reports that follow cover a broad range of topics. Specifically, these reports describe implementations and experimentation with: secure file systems when servers and administrators are untrusted; proportional share allocation for processor scheduling and its interaction with kernel realities such as locks; eventually serializable replicated databases with constant-order dependency checking; compressed file data structures optimized to specific access patterns; atomic, shared object semantics for distributed computing in JAVA; transaction semantics for federated agent databases; and user-level file service offering enhanced memory caching for remote files. All reports include implementations and experimentation. Two involve operating system kernel changes, four use a middleware /library approach and one implements a client/server system. Three involve Linux specific modifications, one is specific to FreeBSD, one extends JAVA programming, and one exploits MPI communications. Evaluations include microbenchmark measurements, formal correctness evaluation, synthetic benchmarks, and more than a couple specifically developed application codes. While not all of these reports report definitely and positively, all involve novelty in either the systems explored or the applications applied and all are worth reading.

Security for a High Performance Commodity Storage Subsystem (CMU-CS-99-160)

description: How do we incorporate security into a high performance commodity storage sub- system? Technology trends and the increasing importance of I/O bound workloads are driving the development of commodity network attached storage devices which deliver both increased functionality and increased performance to end-users. In the network attached world, storage devices co-exist on the network with their clients, application file-managers, and malicious adversaries who seek to bypass system security policies. As storage devices move from behind the protection of a server and become first-class network entities in their own right, they must become actively involved in protecting themselves from network attacks. They must do this while cooperating with higher level applications, such as distributed file systems or database systems, to enforce the application's security policies over storage resources. In this dissertation, I address this problem by proposing a cryptographic capability system which enables application filemanagers to asynchronously make policy decisions while the commodity storage devices synchronously enforce these decisions. This dissertation analyzes a variety of access control schemata that exist in current distributed storage systems. Motivated by the analysis, I propose a basic cryptographic capability system that is flexible enough to efficiently meet the requirements of many distributed storage systems. Next, I explore how a variety of different mechanisms for describing a set of NASD objects can be used to improve the basic capability system. The result is a new design based on remote execution techniques. The new design places more access control processing at the drive in order to deliver increased performance and functional advantages. Based on the performance limitations of software cryptography demonstrated in a prototype implementation of a network attached storage device, I propose and evaluate an alternative to standard message authentication codes. This allows storage devices to precompute some security information and reduces the amount of request-time computation required to protect the integrity of read operations. Finally, I discuss the availability of cryptographic hardware, how much is required for a network attached storage device, and the implications of adding tamper-resistant hardware to a storage device.
