description: The home provides a new and challenging environment for data management. Devices in the home are extremely heterogeneous in terms of computational capability, capacity, and usage model. Yet, ideally, information would be shared easily across them. Current volume-based filesystems do not provide the flexibility to allow these specialized devices to keep an up-to-date copy of the information they require without seeing large amounts of traffic to other, unrelated pieces of information. We propose the use of views to allow devices to subscribe to particular classes of objects. Data views allow devices to see up-to-date information from available devices, and eventual consistency with unavailable devices, for objects of interest without seeing updates to other objects in the system. Views also provide a basis on which to build reliability, data management and search.

description: Based on shortcuts to adiabaticity and quantum Zeno dynamics, we present a protocol to implement quantum state transfer (QST) in a quantum spin-1/2 chain. In the protocol, the complex Hamiltonian of an $N$-site system is simplified, and a simple effective Hamiltonian is present. It is shown that only the control of the coupling strengths between the boundary spins and the bulk spins are required for QST. Numerical simulations demonstrate that the protocol possesses high efficiency and is robust against the decay and the fluctuations of the control fields. The protocol might provide an alternative choice for transferring quantum states via spin chain systems.

description: We present the optical properties of Radio-Loud quasars along the Main Sequence
 (MS) of quasars. A sample of 355 quasars selected on the basis of radio detection was obtained by cross-matching the FIRST survey at 20cm and the SDSS DR12 spectroscopic survey. We consider the nature of powerful emission at the high-Feii end of the MS. At variance with the classical radio-loud sources which are located in the Population B domain of the MS optical plane, we found evidence indicating a thermal origin of the radio emission of the highly accreting quasars of Population A. A detailed description of the sample and the performed analysis can be found in Ganci et al. (2019).

description: Semantic file systems enable users to search for files based on attributes rather than just pre-assigned names. This paper develops and evaluates several new approaches to automatically generating file attributes based on context, complementing existing approaches based on content analysis. Context captures broader system state that can be used to provide new attributes for files, and to propagate attributes among related files; context is also how humans often remember previous items [2], and so should fit the primary role of semantic file systems well. Based on our study of ten systems over four months, the addition of context-based mechanisms, on average, reduces the number of files with zero attributes by 73%. This increases the total number of classifiable files by over 25% in most cases, as is shown in Figure 1. Also, on average, 71% of the content-analyzable files also gain additional valuable attributes.

description: Given a compact Riemannian manifold with boundary, we prove that the space of embedded, which may be improper, free boundary minimal hypersurfaces with uniform area and Morse index upper bound is compact in the sense of smoothly graphical convergence away from finitely many points. We show that the limit of a sequence of such hypersurfaces always inherits a non-trivial Jacobi field when it has multiplicity one. In a forthcoming paper, we will construct Jacobi fields when the convergence has higher multiplicity.
description: We fixed a gap in the construction of Jacobi fields and split the original paper into two parts. The followup paper(the second part) will deal with the construction of Jacobi fields when the convergence has higher multiplicity

description: An excellent hadron to electron discrimination is a crucial aspect of calorimeter-based experiments in astroparticle physics. Standard discrimination techniques require full shower development and fine granularity but in space detectors severe limitations exist due to constraints on dimensions, weight and power consumption. A possible approach is to exploit the different neutron yield of electromagnetic and hadronic showers. NEUCAL is a light and compact innovative neutron detector, to be used as an auxiliary complement of electromagnetic calorimeters. This new approach to neutron counting relies on scintillation detectors which are sensitive to the moderation phase of the neutron component. The NEUCAL prototype has been placed after a conventional calorimeter and tested with high energy beams of pions and positrons. The comparison of experimental data with a detailed Geant4 simulation and the encouraging results obtained are presented.

description: This paper examines whether the impact of environmental regulations differs by the size of the business. We consider the net effect of statutory, enforcement, and compliance asymmetries by estimating the relationship between plant size and pollution abatement expenditures, using establishment-level data on U.S. manufacturers from the Census Bureau’s Pollution Abatement Costs and Expenditures (PACE) survey and from its Annual Survey of Manufactures and Census of Manufactures. We model establishments’ pollution abatement operating costs (PAOC) per unit of economic activity as a function of establishment size, industry, state, and year. Our results show that PAOC intensity increases with establishment and firm size.

description: Timing-accurate storage emulation offers a unique performance evaluation capability: the flexibility of simulation with the reality of experimental measurements. This allows a researcher to experiment with not-yet-existing storage components in the context of real systems executing real applications. As its name suggests, a timing-accurate storage emulator appears to the system to be a real storage component with service times matching a simulation model (or other computational model) of that component. This allows simulated storage components to be plugged into real systems, which can then be used for complete, application-based experimentation. Additionally, timing-accurate storage emulation offers the opportunity to investigate more expressive interfaces between storage and computer systems, permitting forays into the space of hypothetical device functionalities without the difficulties of developing and supporting extensively nonstandard or novel interface actions in prototype or production systems. This dissertation identifies that there is a current and pressing need for a new storage evaluation technique, discusses design issues for achieving accurate per-request service times in a timing-accurate storage emulator, and demonstrates that it is feasible to construct and use such an emulator for interesting system-level experimentation. We built a functional timing-accurate storage emulator and explored its use in experiments involving models of existing storage products, experiments evaluating the potential of nonexistent storage components, and experiments evaluating interactions between modified computer systems and expanded storage device functionality. To experiment with existing and hypothetical storage components in computer systems, we configured our emulator with device models representing a currently-available production disk drive, a hypothetical 50,000 RPM disk drive, and a hypothetical MEMS-based storage device, and executed three application-level workloads against these emulated models. To explore system architectures with expanded device functionality, we applied the principles of timing-accurate storage emulation in an investigation into storage-based intrusion detection systems. This experimentation demonstrates that our emulator accurately reflects the performance of modeled devices, demonstrates the feasibility of including intrusion detection capabilities into a standalone processing-enhanced disk drive, and demonstrates that extensions to existing storage communications paths may be used to transmit and receive information regarding the configuration and operational status of such an enhanced device.

description: Rapid and inexpensive one-pot multicomponent synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione through a condensation reaction of aryl aldehyde, malononitrile or ethyl cyanoacetate and phthalhydrazide catalyzed by water extract of papaya bark ash (WEPBA) solvent medium under microwave irradiation is described. The catalytic medium is used environmentally friendly, and provides several benefits of being simple, inexpensive, high yield, simple work-up and not required hazardous solvent for the reaction. Some of the selected derivatives were characterized by FT-IR, 1H-, and 13C-NMR, and mass spectrometry techniques. The oxidation-reduction properties of the synthesized compounds (4b, 4e, 4f, 4i, and 4k and 6f, 6g, 6h, 6i, and 6j) were studied using cyclic voltammetry (CV). The voltammetry peak current for the oxidation-reduction of the compounds examined at different scan rates. Further, some of the selected 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives were evaluated in vitro antioxidant activity using DPPH assay method. The result appears that, compounds 4b, 4e, 4i, 6f, 6g, and 6h possess significant antioxidant properties in comparison with the ascorbic acid reference.

Inforence: Effective Fault Localization Based on Information-Theoretic Analysis and Statistical Causal Inference

Year: 2017
Subjects: subject: Software Engineering (cs.SE)

description: In this paper, a novel approach, Inforence, is proposed to isolate the suspicious codes that likely contain faults. Inforence employs a feature selection method, based on mutual information, to identify those bug-related statements that may cause the program to fail. Because the majority of a program faults may be revealed as undesired joint effect of the program statements on each other and on program termination state, unlike the state-of-the-art methods, Inforence tries to identify and select groups of interdependent statements which altogether may affect the program failure. The interdependence amongst the statements is measured according to their mutual effect on each other and on the program termination state. To provide the context of failure, the selected bug-related statements are chained to each other, considering the program static structure. Eventually, the resultant cause-effect chains are ranked according to their combined causal effect on program failure. To validate Inforence, the results of our experiments with seven sets of programs include Siemens suite, gzip, grep, sed, space, make and bash are presented. The experimental results are then compared with those provided by different fault localization techniques for the both single-fault and multi-fault programs. The experimental results prove the outperformance of the proposed method compared to the state-of-the-art techniques.

description: Timing-accurate storage emulation fills an important gap in the set of common performance evaluation techniques for proposed storage designs: it allows a researcher to experiment with not-yet-existing storage components in the context of real systems executing real applications. As its name suggests, a timing-accurate storage emulator appears to the system to be a real storage component with service times matching a simulation model of that component. This paper promotes timing-accurate storage emulation by describing its unique features, demonstrating its feasibility, and illustrating its value. A prototype, called the Memulator, is described and shown to produce service times within 2% of those computed by its component simulator for over 99% of requests. Two sets of measurements enabled by the Memulator illustrate its power: (1) application performance on a modern Linux system equipped with a MEMS-based storage device (no such device exists at this time), and (2) application performance on a modern Linux system equipped with a disk whose firmware has been modified (we have no access to firmware source code).

description: A new method is introduced for making X-ray mass determinations of spherical clusters of galaxies. Treating the distribution of gravitating matter as piecewise constant and the cluster atmosphere as piecewise isothermal, X-ray spectra of a hydrostatic atmosphere are determined up to a single overall normalizing factor. In contrast to more conventional approaches, this method relies on the minimum of assumptions, apart from the conditions of hydrostatic equilibrium and spherical symmetry. The method has been implemented as an XSPEC mixing model called CLMASS, which was used to determine masses for a sample of nine relaxed X-ray clusters. Compared to conventional mass determinations, CLMASS provides weak constraints on values of M_500, reflecting the quality of current X-ray data for cluster regions beyond r_500. At smaller radii, where there are high quality X-ray spectra inside and outside the radius of interest to constrain the mass, CLMASS gives confidence ranges for M_2500 that are only moderately less restrictive than those from more familiar mass determination methods. The CLMASS model provides some advantages over other methods and should prove useful for mass determinations in regions where there are high quality X-ray data.

Essays in Design Economics

description: This thesis contains two essays in philosophy of science on the value and application of economic theory and one essay in microeconomics on optimal multidimensional auction design.
On the topic of the value of economic theory in design economics, I propose a philosophical reformulation of scientific realism that is appropriate to the scientific domain of economics (Chapter 2). In virtue of this formulation, I argue that economic theory partly explains the successes of design economics.
In Chapter 4, I advance a unified theory of observer effects across the social sciences, a problem I call reflexive measurement. This theoretical understanding of the role of reflexivity extends more generally to all aspects of science including prediction and theorizing. I also examine the role of economic theory in addressing this problem.
In addition to these two philosophical contributions, Chapter 3 is an extended exploration of optimal auction design in the multidimensional setting of a single good with multiple quality levels using simulations. This work examines whether the exclusive-buyer mechanism is optimal and offers several conjectures concerning qualitative properties of optimal mechanisms in this analytically intractable setting.

description: In the current research, a new therapeutically active ethyl-4-(2,4-methoxyphenyl)-1,2,3,4-tetrahydro-6-methyl-2-thioxopyrimidine-5-carboxylate (DMPC) prepared by the Biginelli reaction was found to possess effective antioxidant and thrombolytic activities. The geometry of the DMPC was confirmed by the single crystal X-ray diffraction analysis and DFT studies carried out by B3LYP6-311++G (d,p) method and the results have been compared with the actual values. The Mulliken charge distribution, molecular electrostatic potential (MEP) surface, HOMO and LUMO of the DMPC were calculated by victimization a similar level theory. NLO of the DMPC was studied from the optimized geometry. The drug receptor interactions of the molecule were studied by molecular docking using auto dock 4.2.

description: We report the detailed study on transport properties of ZrB2 single crystal, a predicted topological nodal-line semimetal. ZrB2 exhibits extremely large magnetoresistance as well as field-induced resistivity upturn and plateau. These behaviors can be well understood by the two-band model with the perfect electron - hole compensation and high carrier mobilities. More importantly, the electrons with small effective masses and nontrivial Berry phase have significantly high density when compared to those in known topological semimetals. It strongly suggests that ZrB2 hosts Dirac-like nodal-line fermions.

description: Interest in thin clients is very high today because of frustration with the growing total cost of ownership of personal computers. Unfortunately, thin clients may not meet the usability goal of crisp interactive response. This paper shows that the adequacy of thin-client computing is highly variable, and depends on both the application and the available network quality. For intensely interactive applications, the tight control of end-to-end network latency required by thin clients may be hard to guarantee at large scale. The paper advocates the concept of stateless thick clients, and describes how they may reduce total cost of ownership while preserving good interactive performance.

description: We study the multi-wavelength properties of a set of 171 Ly-alpha emitting candidates at redshift z = 2.25 found in the COSMOS field, with the aim of understanding the underlying stellar populations in the galaxies. We especially seek to understand what the dust contents, ages and stellar masses of the galaxies are, and how they relate to similar properties of Ly-alpha emitters at other redshifts. The candidates here are shown to have different properties from those of Ly-alpha emitters found at higher redshift, by fitting the spectral energy distributions (SEDs) using a Monte-Carlo Markov-Chain technique and including nebular emission in the spectra. The stellar masses, and possibly the dust contents, are higher, with stellar masses in the range log M_* = 8.5 - 11.0 M_sun and A_V = 0.0 - 2.5 mag. Young population ages are well constrained, but the ages of older populations are typically unconstrained. In 15% of the galaxies only a single, young population of stars is observed. We show that the Ly-alpha fluxes of the best fit galaxies are correlated with their dust properties, with higher dust extinction in Ly-alpha faint galaxies. Testing for whether results derived from a light-weighted stack of objects correlate to those found when fitting individual objects we see that stellar masses are robust to stacking, but ages and especially dust extinctions are derived incorrectly from stacks. We conclude that the stellar properties of Ly-alpha emitters at z = 2.25 are different from those at higher redshift and that they are diverse. Ly-alpha selection appears to be tracing systematically different galaxies at different redshifts.

description: Pyridopyrimidine are heterocyclic molecules enclosing fused pyridine and pyrimidine rings. Owing to its fascinating core structure and pharmacological applications a series of 7-([1,1′-biphenyl]-4-yl)-5-arylpyrido[2,3-d]pyrimidine-2,4(1H,3H)-diones were synthesized and characterized using IR, 1H, 13C NMR and Mass spectral techniques. The antibacterial, antioxidant and anticancer activities were investigated for the synthesized compound 5a-5f. Compounds with electron-donating groups showed excellent free radical scavenging activity. Halogen-substituted compounds showed more potent antimicrobial and anticancer activity than other derivatives in comparison with their respective standards. Based on the IC50 value obtained from anticancer activity, 5c was further analyzed for apoptosis by AO/EB staining method. The findings suggested early apoptosis in the MCF-7 cell line. Molecular Docking studies of the synthesized compounds were performed with Kinase 1 inhibitors (PDB id: 2YEX), 5c exposed good docking results with minimum binding energy. Further, these compounds were acknowledged as orally active drug candidates from in-silico ADMET studies. Computational analysis supports biological findings indicating compound 5c as a promising anticancer agent against the human breast cancer MCF-7 cell line.
Indeterminism in Physics, Classical Chaos and Bohmian Mechanics. Are Real Numbers Really Real?

description: It is usual to identify initial conditions of classical dynamical systems with mathematical real numbers. However, almost all real numbers contain an infinite amount of information. I argue that a finite volume of space can't contain more than a finite amount of information, hence that the mathematical real numbers are not physically relevant. Moreover, a better terminology for the so-called real numbers is ``random numbers'', as their series of bits are truly random. I propose an alternative classical mechanics, which is empirically equivalent to classical mechanics, but uses only finite-information numbers. This alternative classical mechanics is non-deterministic, despite the use of deterministic equations, in a way similar to quantum theory. Interestingly, both alternative classical mechanics and quantum theories can be supplemented by additional variables in such a way that the supplemented theory is deterministic. Most physicists straightforwardly supplement classical theory with real numbers to which they attribute physical existence, while most physicists reject Bohmian mechanics as supplemented quantum theory, arguing that Bohmian positions have no physical reality.

Numerical Study of the Exchange Flow of the Persian Gulf Using an Extended Total Exchange Flow Analysis Framework

description: The Total Exchange Flow analysis framework computes consistent bulk values quantifying the estuarine exchange flow using salinity coordinates since salinity is the main contributor to density in estuaries and the salinity budget is entirely controlled by the exchange flow. For deeper and larger estuaries temperature may contribute equally or even more to the density. That is why we included potential temperature as a second coordinate to the Total Exchange Flow analysis framework, which allows gaining insights in the potential temperature-salinity structure of the exchange flow as well as to compute consistent bulk potential temperature and therefore heat exchange values with the ocean. We applied this theory to the exchange flow of the Persian Gulf, a shallow, semienclosed marginal sea, where dominant evaporation leads to the formation of hypersaline and dense Gulf water. This drives an inverse estuarine circulation which is analyzed with special interest on the seasonal cycle of the exchange flow. The exchange flow of the Persian Gulf is numerically simulated with the General Estuarine Transport Model from 1993 to 2016 and validated against observations. Results show that a clear seasonal cycle exists with stronger exchange flow rates in the first half of the year. Furthermore, the composition of the outflowing water is investigated using passive tracers, which mark different surface waters. The results show that in the first half of the year, most outflowing water comes from the southern coast, while in the second half most water originates from the northwestern region.

description: We formulate mimetic theory in f(T) teleparallel gravity where T is torsion scalar. It is shown that the construction of the mimetic theory in the teleparallel gravity requires the vierbeins to be left unchanged and the confomal transformation performed on the Minkowski metric of the tangent space. It is further argued that the conformal degree of freedom in this teleparallel mimetic theory becomes dynamical and mimics the behavior of cold dark matter. We also show that it is possible to employ the Lagrange multipliers method to formulate the mimetic theory in an f(T) theory without any auxiliary metric. The mimetic f(T) theory is examined by the method of dynamical system and it is found that there are five fixed points representing inflation, radiation, matter, mimetic dark matter and dark energy dominated eras in the theory if some conditions are satisfied. We examined the power-law model and its phase trajectories with these conditions.

description: To meet the bandwidth needs of modern computer systems, parallel storage systems are evolving beyond RAID levels 1 through 5. The Parallel Data Lab at Carnegie Mellon University has constructed three Scotch parallel storage testbeds to explore and evaluate five directions in RAID evolution: first, the development of new RAID architectures to reduce the cost/performance penalty of maintaining redundant data; second, an extensible software framework for rapid prototyping of new architectures; third, mechanisms to reduce the complexity of and automate error-handling in RAID subsystems; fourth, a file system extension that allows serial programs to exploit parallel storage; and lastly, a parallel file system that extends the RAID advantages to distributed, parallel computing environments. This paper describes these five RAID evolutions and the testbeds in which they are being implemented and evaluated.
How should fishing mortality be distributed under balanced harvesting?

description: Zhou and Smith (2017) investigate different multi-species harvesting scenarios using a simple Holling-Tanner model. Among these scenarios are two methods for implementing balanced harvesting, where fishing is distributed across trophic levels in accordance with their productivity. This note examines the effects of a different quantitative implementation of balanced harvesting, where the fishing mortality rate is proportional to the total production rate of each trophic level. The results show that setting fishing mortality rate to be proportional to total production rate, rather than to productivity per unit biomass, better preserves trophic structure and provides a crucial safeguard for rare and threatened ecological groups. This is a key ingredient of balanced harvesting if it is to meet its objective of preserving biodiversity.

East Atlantic Pattern Drives Multidecadal Atlantic Meridional Overturning Circulation Variability During the Last Glacial Maximum

description: The variability of the Atlantic meridional overturning circulation (AMOC) and its governing processes during the Last Glacial Maximum (LGM) is investigated in the Kiel Climate Model. Under LGM conditions, multidecadal AMOC variability is mainly forced by the surface heat flux variability linked to the East Atlantic pattern (EAP). In contrast, the multidecadal AMOC variability under preindustrial conditions is mainly driven by the surface heat flux variability associated with the North Atlantic Oscillation. Stand-alone atmosphere model experiments show that relative to preindustrial conditions, the change in AMOC forcing under LGM conditions is tightly linked to the differences in topography.
Dwarf nova oscillations and quasi-periodic oscillations in cataclysmic variables -- VI. Spin rates, propellering, and coherence

description: We examine published observations of dwarf nova oscillations (DNOs) on the rise and decline of outbursts and show that their rates of change are in reasonable agreement with those predicted from the magnetic accretion model. We find evidence for propellering in the late stages of outburst of several dwarf novae, as shown by reductions in EUVE fluxes and from rapid increases of the DNO periods. Reanalysis of DNOs observed in TY PsA, which had particularly large amplitudes, shows that the apparent loss of coherence during late decline is better described as a regular switching between two nearby periods. It is partly this and the rapid deceleration in some systems that make the DNOs harder to detect. We suggest that the 28.95 s periodicity in WZ Sge, which has long been a puzzle, is caused by heated regions in the disc, just beyond the corotation radius, which are a consequence of magnetic coupling between the primary and gas in the accretion disc. This leads to a possible new interpretation of the `longer period DNOs' (lpDNOs) commonly observed in dwarf novae and nova-like variables.

description: Two popular examples of first-order optimization methods over linear spaces are coordinate descent and matching pursuit algorithms, with their randomized variants. While the former targets the optimization by moving along coordinates, the latter considers a generalized notion of directions. Exploiting the connection between the two algorithms, we present a unified analysis of both, providing affine invariant sublinear $\mathcal{O}(1/t)$ rates on smooth objectives and linear convergence on strongly convex objectives. As a byproduct of our affine invariant analysis of matching pursuit, our rates for steepest coordinate descent are the tightest known. Furthermore, we show the first accelerated convergence rate $\mathcal{O}(1/t^2)$ for matching pursuit and steepest coordinate descent on convex objectives.

description: For an interval finite quiver $Q$, we introduce a class of flat representations. We classify the indecomposable projective objects in the category $\mathrm{rep}(Q)$ of pointwise finite dimensional representations. We show that an object in $\mathrm{rep}(Q)$ is projective if and only if it is a direct sum of countably generated flat representations.

description: Survivable storage systems mask faults. A protocol family shifts the decision of which types of faults from implementation time to data-item creation time. If desired, each data-item can be protected from different types and numbers of faults with changes only to client-side logic. This paper presents proofs of the safety and liveness properties for a family of storage access protocols that exploit data versioning to efficiently provide consistency for erasure-coded data. Members of the protocol family may assume either a synchronous or asynchronous model, can tolerate hybrid crash-recovery and Byzantine failures of storage-nodes, may tolerate either crash or Byzantine clients, and may or may not allow clients to perform repair. Additional protocol family members for synchronous systems under omission and fail-stop failure models of storage-nodes are developed.
