The Computational Complexity of Propositional Cirquent Calculus
Creators: name: Bauer, Matthew Steven
Publisher: name: arXiv
Year: 2014
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: Introduced in 2006 by Japaridze, cirquent calculus is a refinement of sequent calculus. The advent of cirquent calculus arose from the need for a deductive system with a more explicit ability to reason about resources. Unlike the more traditional proof-theoretic approaches that manipulate tree-like objects (formulas, sequents, etc.), cirquent calculus is based on circuit-style structures called cirquents, in which different "peer" (sibling, cousin, etc.) substructures may share components. It is this resource sharing mechanism to which cirquent calculus owes its novelty (and its virtues). From its inception, cirquent calculus has been paired with an abstract resource semantics. This semantics allows for reasoning about the interaction between a resource provider and a resource user, where resources are understood in the their most general and intuitive sense. Interpreting resources in a more restricted computational sense has made cirquent calculus instrumental in axiomatizing various fundamental fragments of Computability Logic, a formal theory of (interactive) computability. The so-called "classical" rules of cirquent calculus, in the absence of the particularly troublesome contraction rule, produce a sound and complete system CL5 for Computability Logic. In this paper, we investigate the computational complexity of CL5, showing it is $Σ_2^p$-complete. We also show that CL5 without the duplication rule has polynomial size proofs and is NP-complete.

description: In this paper, the digital self-interference (SI) cancellation in a single radio frequency (RF) chain massive multi-input multi-output (MIMO) full-duplex (FD) orthogonal frequency division multiplexing (OFDM) system with phase noise is studied. To compensate the phase noise, which introduces SI channel estimation error and thus degrades the SI cancellation performance, a weighted linear SI channel estimator is derived to minimize the residual SI power in each OFDM symbol. The digital SI cancellation ability of the proposed method, which is defined as the ratio of the SI power before and after the SI cancellation, is analyzed. Simulation results show that the proposed optimal linear SI channel estimator significantly outperforms the conventional least square (LS) estimator in terms of the SI cancellation ability for the cases with strong SI and low oscillator quality.

description: To investigate the effect of frailty education on the perception of frailty risk for urban and rural older adults. Forty adults completed a frailty perception survey, the Edmonton Frail Scale (EFS), and participated in a 6-week frailty intervention program. Urban older adults increased knowledge of frailty including identification of frailty risk (.0035, p < .05), importance of good nutrition as we age (.0015, p < .05) and confidence in accessing community resources (.000031, p < .05). Aggregate site results showed increased accessibility to frailty education including risk of frailty (2.24576E-12, p < .05), frailty criteria (3.29825E-12, p < .05), and reduction of frailty risk (1.21856E-09, p < .05) for rural and urban older adults. Fall prevention knowledge improved at both Urban and Rural A sites (.00021, p < .05). The frailty education provided to urban and rural community dwelling older adults supported a change in the perceptions of frailty risk after participation in the program.
Topological invariants of complex energy plane in non-Hermitian systems

description: Non-Hermitian systems as theoretical models of open or dissipative systems exhibit rich novel physical properties and fundamental issues in condensed matter physics.We propose a generalized local-global correspondence between the pseudo-boundary states in the complex energy plane and topological invariants of quantum states. We find that the patterns of the pseudo-boundary states in the complex energy plane mapped to the Brillouin zone are topological invariants against the parameter deformation. We demonstrate this approach by the non-Hermitian Chern insulator model. We give the consistent topological phases obtained from the Chern number and vorticity. We also find some novel topological invariants embedded in the topological phases of the Chern insulator model, which enrich the phase diagram of the non-Hermitian Chern insulators model beyond that predicted by the Chern number and vorticity. We also propose a generalized vorticity and its flipping index to understand physics behind this novel local-global correspondence and discuss the relationships between the local-global correspondence and the Chern number as well as the transformation between the Brillouin zone and the complex energy plane. These novel approaches provide insights to how topological invariants may be obtained from local information as well as the global property of quantum states, which is expected to be applicable in more generic non-Hermitian systems.

description: Mass loss remains one of the primary uncertainties in stellar evolution. In the most massive stars, mass loss dictates the circumstellar medium and can significantly alter the fate of the star. Mass loss is caused by a variety of wind mechanisms and also through binary interactions. Supernovae are excellent probes of this mass loss, both the circumstellar material and the reduced mass of the hydrogen-rich envelope. In this paper, we focus on the effects of reducing the hydrogen-envelope mass on the supernova light curve, studying both the shock breakout and peak light curve emission for a wide variety of mass loss scenarios. Even though the trends of this mass loss will be masked somewhat by variations caused by different progenitors, explosion energies, and circumstellar media, these trends have significant effects on the supernova light-curves that should be seen in supernova surveys. We conclude with a comparison of our results to a few key observations.

RETI DI CONTROLLO A CAPACIT� COMMUTATE PER CONVERTITORI DC/DC PWM
Creators: name: DELLA GIUSTINA, DAVIDE
Publisher: name: Universit� degli Studi di Milano
Year: 2010

description: The thesis describes the disign of a digitally programmable switched capacitor filter. The filter was employed as external feedback network to control a buck power cell, according to the zero/pole cancellation method. Static and dynamic characterizations of the close loop converter showed good agreement between theoretical model and experimental results. The circuit is also employed for educational purpose, because it easily highlights the different dynamic behaviors of power devices such as limit cycle, chaotic behavior and local bifurcations. The filter and the converter were simulated by both Matlab, Simulink, and SPICE. An important part of the work was the sensitivity analysis of the circuit with respect to the quantization effect of its digitally programmable coefficients and to other statistical parameters.
Dwarf Galaxy Planes: the discovery of symmetric structures in the Local Group

description: Both major galaxies in the Local Group (LG) are surrounded by thin planes of mostly co-orbiting satellite galaxies, the vast polar structure (VPOS) around the Milky Way (MW) and the Great Plane of Andromeda (GPoA) around M31. We summarize the current knowledge concerning these structures and compare their relative orientations and properties in a common coordinate system. The existence of coherent satellite structures motivates an investigation of the distribution of the more distant non-satellite galaxies in the LG. This results in the discovery of two planes (diameters of 1-2 Mpc) which contain almost all nearby non-satellite galaxies. The two LG planes are surprisingly symmetric, inclined by only 20 deg relative to the galactic disc of M31, similarly thin (heights of ~60 kpc) and have near-to-identical offsets from the MW and M31. They are inclined relative to each other by 35 deg. Comparing the plane orientations with each other and with additional features indicates an intimate connection between the VPOS and the GPoA. They are both polar to the MW, have similar orbital directions and are inclined by ~45 deg relative to each other. The Magellanic Stream approximately aligns with the VPOS and the GPoA, but also shares its projected position and line-of-sight velocity trend with the dominating structure of non-satellite dwarf galaxies. The proper motion of M31 indicates a prograde orbit of the MW-M31 system, the VPOS and the GPoA. The alignment with other features such as the Supergalactic Plane and the over-density in hypervelocity stars are discussed as well. We end with a summary of proposed scenarios trying to explain the LG galaxy structures as either originating from cosmological structures or from tidal debris of a past galaxy encounter. There currently exists no full detailed model which satisfactorily explains the existence of the thin symmetric LG planes. (abridged)

description: We propose a practical network code for the wireless two-way relay channel where all nodes communicate in full duplex (FD) mode. The physical layer network coding (PNC) operation is applied with the FD operating nodes, reducing the transmission time to a single time slot, hence doubling the spectral efficiency when compared to classical PNC systems. In our system model, binary phase shift keying modulated signals are transmitted over Rayleigh fading channels. We derive the theoretical error rates at relay and end nodes according to the maximum likelihood detection rule, in case of non-ideal self-interference cancellation. Theoretical results are also verified via simulations.
INTERPRETATION OF TRAUMA AND TAPHONOMY IN A MODERN KNOWN SKELETAL POPULATION: IMPLICATION FOR FORENSIC ANTHROPOLOGY
Creators: name: CAPPELLA, ANNALISA
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: In Forensic Anthropology, trauma analysis is essential for a correct understanding of the cause and the modality of death as well as for the interpretation of previous traumatic events which occurred in life. Both have important implications in criminal and humanitarian scenarios: to demonstrate whether a crime was committed, and to ascertain torture and maltreatment. Nevertheless, the assessment of a traumatic event, whether antemortem, perimortem or potmortem, is extremely challenging and often limited and altered by multiple variables, namely taphonomy. Few are the validated scientific methods which can help anthropologists in the interpretation of skeletal trauma, and which are often limited by the lack of known skeletal material on which to conduct research in order to acquire data, to validate methods and to study and create theoretical trauma and taphonomy models. Among the many known documented skeletal collections already presented officially to the international scientific community very few are equipped also with known/control data on trauma, and cause and modality of death. The Milan cemeterial Skeletal Collection, which is only part of the more consistent Milan Osteological Skeletal Collection housed at LABANOF (University of Milan) is one of the latter, and its presence has offered the chance to conduct research on the difficult field of trauma and taphonomy included in the Ph.D project. The first ever anthropological study of the skeletal sample of the Milan skeletal collection here presented, has been the starting point which permitted us to highlight the numerous diagnostic difficulties concerning trauma analysis and has provided the material on which to conduct the applied research for analysing the state of the art currently used by the discipline. As a consequence of the many limits arising from the first two research lines (on the diagnosis of antemortem lesions as well as the identification of perimortem injury), which appeared not satisfactory enough for a correct interpretation of skeletal lesions, the research has focused on the novel field of blood taphonomy in order to provide knowledge for the use of cell components and biomarkers as indicators of vitality and survival on skeletal trauma which represents more reliable future possible alternative solutions.
SET-UP AND APPLICATION OF BIOTECHNOLOGICAL METHODS IN AVIAN FIELD

Year: 2013

description: The use of biotechnology in avian field has been increased in the last decade especially on the track of the complete sequencing of chicken genome and on the global threat of avian flu pandemic which alerted the scientific community worldwide. Nevertheless, it is still on the whole a minor and spotty approach in avian field. Matter-of-factly, birds can be roughly divided into two groups on a research point of view: poultry and non-poultry (companion and wild birds). The economic impact of the latter is usually scarce if compared to the former and to other veterinary and human contexts. Thus, routine use of laboratory diagnostic tools including biotechnological methods is usually limited to the more expensive psittacines species (i.e. DNA-based determination of sex, diagnosis of chlamydiosis etc.) or to endangered species. As for poultry, extensive use of biotechnology is performed in vaccine research and genetic selection with a secondary role in avian and comparative pathology. Besides, chicken has historically assumed the role of avian model. Consequently, birds are often considered an uniform class but they are not, and a deep knowledge of the huge diversity which can exist among the several avian species is fundamental to correctly approach and interpret avian research no matter using biotechnology or not. For all these reasons it seemed an unique occasion to match the documented experience and activity in avian field (acquired during a previous doctorate) to biotechnological methods as the subject of this doctoral thesis. After a brief introduction revising fundamental principles of the molecular methods used, this thesis is divided into two parts. The first is focused on avian immunity and in particular on the TIR8-SIGIRR receptor which has been thoroughly investigate in chickens as a model for avian species and with an importance in itself as an ubiquitously diffused food production animal. The second part is made up of some diagnostic challenges arisen during the routine diagnostic activity of the Section of Avian Pathology of the Department of Veterinary Science and Public Health.

description: Security has become, nowadays, a major concern for the organizations as the majority of its applications are exposed to Internet, which increases the threats of security considerably. Thus, the solution is to improve tools and mechanisms to strengthen the protection of applications against attacks and ensure the different security objectives. Among solutions we will talking about, in this paper, there is Mutation Analysis which is a technique of test that evaluates the quality of software tests and their ability to detect errors, It also compares the criteria and test generation strategies. In this study we will use the Mutation Analysis as a mean to qualify the penetration tests, and then, apply this technique in the security mechanisms and exactly on the mechanisms of access control. At the end we will propose a method for the elimination of hidden mechanisms for access control that will allow the access control policy to evolve.

description: We study the dynamical properties of the Dicke model for increasing spin length, as the system approaches the limit of a classical spin. First, we describe the emergence of collective excitations above the groundstate that converge to the coupled spin-oscillator oscillations found in the classical limit. The corresponding Green functions reveal quantum dynamical signatures close to the superradiant quantum phase transition. Second, we identify signatures of classical quasi-periodic orbits in the quantum time evolution using numerical time-propagation of the wave function. The resulting phase space plots are compared to the classical trajectories. We complete our study with the analysis of individual eigenstates close to the quasi-periodic orbits.

description: We consider a class of on-shell constrained mass variables that are 3+1 dimensional generalizations of the Cambridge $M_{T2}$ variable and that automatically incorporate various assumptions about the underlying event topology. The presence of additional on-shell constraints causes their kinematic distributions to exhibit sharper endpoints than the usual $M_{T2}$ distribution. We study the mathematical properties of these new variables, e.g., the uniqueness of the solution selected by the minimization over the invisible particle 4-momenta. We then use this solution to reconstruct the masses of various particles along the decay chain. We propose several tests for validating the assumed event topology in missing energy events from new physics. The tests are able to determine: 1) whether the decays in the event are two-body or three-body, 2) if the decay is two-body, whether the intermediate resonances in the two decay chains are the same, and 3) the exact sequence in which the visible particles are emitted from each decay chain.

description: We present the first theoretical study of metals in damped Ly-alpha (DLA) systems at redshift z=7. The features of cold, primordial gas are studied by means of N-body, hydro, chemistry simulations, including atomic and molecular non-equilibrium chemistry, cooling, star formation for population III and population II-I regimes, stellar evolution, cosmic metal spreading according to proper yields (for He, C, O, Si, Fe, Mg, S, etc.) and lifetimes, and feedback effects. Theoretical expectations are then compared to recently available constraints from DLA observations. We find that DLA galaxies at z=7 account for 10 per cent of the whole galaxy population and for most of the metal-poor galaxies at these epochs. About 7 per cent of these DLA galaxies contain purely pristine material and 34 per cent of them consist of very weakly polluted gas, being, therefore, suitable candidate s as population III sites. The remaining 59 per cent are enriched above ~10^{-4} Zsun. Additionally, DLA candidates appear to have: gas masses ~3x10^{20} cm^{-2}. They present no or weak correlations between their gas mass and Z, NHI, or x_mol; a moderate correlation between x_mol and Z, linked to the ongoing molecular-driven star formation and metal pollution processes; a mild anti-correlation between NHI and x_mol, due to H depletion into molecules; and a chemical content that is subject to environmental dependencies.

description: Solar active longitudes show a characteristic migration pattern in the Carrington coordinate system when they can be identified at all. By following this migration, the longitudinal activity distribution around the center of the band can be determined. The halfwidth of the distribution is found to be varying in Cycles 21 - 23, and in some time intervals it was as narrow as 20 - 30 degrees. It was more extended around maximum but it was also narrow when the activity jumped to the opposite longitude. Flux emergence exhibited a quasi-periodic variation within the active zone with a period of about 1.3 years. The path of the active longitude migration does not support the view that it might be associated with the 11-year solar cycle. These results were obtained for a limited time interval of a few solar cycles and, bearing in mind uncertainties of the migration path definition, are only indicative. For the major fraction of dataset no systematic active longitudes were found. Sporadic migration of active longitudes was identified only for Cycles 21 - 22 in the northern hemisphere and Cycle 23 in the southern hemisphere.

description: We show that large spin fermions have very rich spin structures. The local spin order of a spin-$f$ Fermi gas is a linear combination of $2f$ (particle-hole) angular momentum states, $L=1,..,2f$. $L=1, 2$ represent ferromagnetic and nematic spin order, while $L\geq 3$ are higher spin orders that has no analog in spin-1/2 systems. Each $L$ spin sector is characterized as $L$ pairs of antipodal points on a sphere. Model calculations show that some of these spin-orders have the symmetry of Platonic solid, and many of them have non-abelian line defects.

description: The method of defining quantum joint probabilities of two events is applied to a multimode system of trapped Bose-condensed atoms. The coherent modes are generated by modulating the trapping potential with an alternating field with a frequency in resonance with a transition frequency between two coherent modes. The system is subjected to nondestructive measurements randomly influencing the phase difference of the modes. The joint probability of observing two events, corresponding to the observation of two states, is calculated by employing the channel-state duality. The interference term in the joint probability can arise when the composite events form an entangled prospect and the system state is also entangled. This interference is due to the uncertainty induced by nondestructive measurements.

Vernacular Toolbox; Strategies for Modernizing Traditional Houses in Rural China

Subjects: classificationCode: 330102

description: This PhD research is drawn from the reflection on my work in rural China over the past 17 years, beginning as a partnership (Rural Urban Framework with Joshua Bolchover) and from the onset of this PhD as individual and other collaborative practice work since 2016. The work examines the impact of urbanization and globalization on rural lifestyle and livelihood in China through the detailed study of adaptations made to ancestral dwellings by local builders, followed by design proposals and built prototypes to anticipate the future of the traditional house.

The research demonstrates various approaches to the contribution architects can make to the evolution of vernacular architecture or an architecture without architects (a reference to previous considerations of the topic). Through a set of diverse projects, the research reveals the equally diverse starting points I have explored for the renovation of traditional building types, resulting in strategies which address the urban, programmatic, constructional, material and detail transformations of vernacular architecture. In turn, the process of designing and building projects reveals some of the unique potentialities (and even contradictions) of the urbanization process in China. As such, it is research operating at two scales: the domestic scale detail, and the urban context, making architectural interventions which learn from and lead to a better understanding of the dynamic, rapidly changing context in which they occur.

description: We present the first public version (v0.2) of the open-source and community-developed Python package, Astropy. This package provides core astronomy-related functionality to the community, including support for domain-specific file formats such as Flexible Image Transport System (FITS) files, Virtual Observatory (VO) tables, and common ASCII table formats, unit and physical quantity conversions, physical constants specific to astronomy, celestial coordinate and time transformations, world coordinate system (WCS) support, generalized containers for representing gridded as well as tabular data, and a framework for cosmological transformations and conversions. Significant functionality is under active development, such as a model fitting framework, VO client and server tools, and aperture and point spread function (PSF) photometry tools. The core development team is actively making additions and enhancements to the current code base, and we encourage anyone interested to participate in the development of future Astropy versions.

description: Efficient and timely calculations of Machine Learning (ML) algorithms are essential for emerging technologies like autonomous driving, the Internet of Things (IoT), and edge computing. One of the primary ML algorithms used in such systems is Convolutional Neural Networks (CNNs), which demand high computational resources. This requirement has led to the use of ML accelerators like GPGPUs to meet design constraints. However, selecting the most suitable accelerator involves Design Space Exploration (DSE), a process that is usually time-consuming and requires significant manual effort. Our work presents approaches to expedite the DSE process by identifying the most appropriate GPGPU for CNN inferencing systems. We have developed a quick and precise technique for forecasting the power and performance of CNNs during inference, with a MAPE of 5.03% and 5.94%, respectively. Our approach empowers computer architects to estimate power and performance in the early stages of development, reducing the necessity for numerous prototypes. This saves time and money while also improving the time-to-market period.
Noise Weighting in the Design of ΔΣ Modulators (with a Psychoacoustic Coder as an Example)
Creators: name: Callegari, Sergio
name: Bizzarri, Federico
Publisher: name: arXiv
Year: 2013
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: A design flow for ΔΣ modulators is illustrated, allowing quantization noise to be shaped according to an arbitrary weighting profile. Being based on FIR NTFs, possibly with high order, the flow is best suited for digital architectures. The work builds on a recent proposal where the modulator is matched to the reconstruction filter, showing that this type of optimization can benefit a wide range of applications where noise (including in-band noise) is known to have a different impact at different frequencies. The design of a multiband modulator, a modulator avoiding DC noise, and an audio modulator capable of distributing quantization artifacts according to a psychoacoustic model are discussed as examples. A software toolbox is provided as a general design aid and to replicate the proposed results.

description: Magnetic helicity is an important concept in solar physics, with a number of theoretical statements pointing out the important role of magnetic helicity in solar flares and coronal mass ejections (CMEs). Here we construct a sample of 47 solar flares, which contains 18 no-CME-associated confined flares and 29 CME-associated eruptive flares. We calculate the change ratios of magnetic helicity and magnetic free energy before and after these 47 flares. Our calculations show that the change ratios of magnetic helicity and magnetic free energy show distinct different distributions in confined flares and eruptive flares. The median value of the change ratios of magnetic helicity in confined flares is $-0.8$%, while this number is $-14.5$% for eruptive flares. For the magnetic free energy, the median value of the change ratios is $-4.3$% for confined flares, whereas this number is $-14.6$% for eruptive flares. This statistical result, using observational data, is well consistent with the theoretical understandings that magnetic helicity is approximately conserved in the magnetic reconnection, as shown by confined flares, and the CMEs take away magnetic helicity from the corona, as shown by eruptive flares.

description: Today's software quality assurance techniques are often applied in isolation. Consequently, synergies resulting from systematically integrating different quality assurance activities are often not exploited. Such combinations promise benefits, such as a reduction in quality assurance effort or higher defect detection rates. The integration of inspection and testing, for instance, can be used to guide testing activities. For example, testing activities can be focused on defect-prone parts based upon inspection results. Existing approaches for predicting defect-prone parts do not make systematic use of the results from inspections. This article gives an overview of an integrated inspection and testing approach, and presents a preliminary case study aiming at verifying a study design for evaluating the approach. First results from this preliminary case study indicate that synergies resulting from the integration of inspection and testing might exist, and show a trend that testing activities could be guided based on inspection results.

description: We have conducted a near-infrared spectroscopic survey of 47 candidate counterparts to X-ray sources discovered by the Chandra X-ray Observatory near the Galactic Center (GC). Though a significant number of these astrometric matches are likely to be spurious, we sought out spectral characteristics of active stars and interacting binaries, such as hot, massive spectral types or emission lines in order to corroborate the X-ray activity and certify the authenticity of the match. We present three new spectroscopic identifications, including a Be high mass X-ray binary (HMXB) or a gamma Cassiopeiae (Cas) system, a symbiotic X-ray binary and an O-type star of unknown luminosity class. The Be HMXB/gamma Cas system and the symbiotic X-ray binary are the first of their classes to be spectroscopically identified in the GC region.

description: This work considers gradient-based mesh optimization, where we iteratively optimize for a 3D surface mesh by representing it as the isosurface of a scalar field, an increasingly common paradigm in applications including photogrammetry, generative modeling, and inverse physics. Existing implementations adapt classic isosurface extraction algorithms like Marching Cubes or Dual Contouring; these techniques were designed to extract meshes from fixed, known fields, and in the optimization setting they lack the degrees of freedom to represent high-quality feature-preserving meshes, or suffer from numerical instabilities. We introduce FlexiCubes, an isosurface representation specifically designed for optimizing an unknown mesh with respect to geometric, visual, or even physical objectives. Our main insight is to introduce additional carefully-chosen parameters into the representation, which allow local flexible adjustments to the extracted mesh geometry and connectivity. These parameters are updated along with the underlying scalar field via automatic differentiation when optimizing for a downstream task. We base our extraction scheme on Dual Marching Cubes for improved topological properties, and present extensions to optionally generate tetrahedral and hierarchically-adaptive meshes. Extensive experiments validate FlexiCubes on both synthetic benchmarks and real-world applications, showing that it offers significant improvements in mesh quality and geometric fidelity.
