title: Automatic Identification and Recovery of Obfuscated Android Apps
Creators: name: Glanz, Leonid
Publisher: name: UNSPECIFIED
Year: 2020

description: Every day, developers add new applications (apps) to the Google Play Store, which ease users' lives and entertain them. The rapid development of these apps is only possible through the provision of software libraries whose functionality can be directly integrated into an app without creating it from scratch. For instance, some libraries provide extended possibilities for displaying content or additional support for specific networking capabilities. All these libraries are bundled with the main application code into one binary to avoid delays due to the loading of external functionality. The wide distribution of Android apps and the high turnover in this market attracts criminal actors (attackers). These attackers decompile the apps, integrate additional ad libraries or malware, and republish them. Through this approach, they use the apps’ popularity to trick users into downloading their repackaged apps. To prevent such malicious practices, developers and producers of libraries have begun to obfuscate their apps to make the decompilation process more challenging. However, the obfuscation of apps is not only done by developers but also by attackers to make the detection of copyright infringement harder or hide their malicious intent. While analysts try to protect the developers’ copyright and the privacy and security of app users, code obfuscation hinders them from identifying libraries and repackaged apps, detecting obfuscated names and strings, and recovering them. The obfuscated code might contain not only malware but also vulnerabilities or unauthorized access to private data. This dissertation introduces different approaches that support the analyses mentioned above using static analysis, dynamic analysis, and machine learning. Since the obfuscation of repackaged apps makes it difficult to distinguish between library and app code, we present approaches for library detection, separation of app code, and mapping of library code. We evaluated the effectiveness of these approaches under the influence of different obfuscation techniques. Furthermore, we present our approach for identifying repackaged apps that uses our library identification to measure the similarity between repackaged and original apps without the influence of library code, which would distort the measurement. Further contributions support the recovery of names from obfuscated entities in library code. Finally, we presented an approach for identifying and recovering obfuscated strings that supports data-flow analyses. Using our approaches, we outperformed all state-of-the-art competitors. Furthermore, we analyzed in total over 100,000 apps for obfuscated names, obfuscated libraries, obfuscated strings, and repackaged apps.

description: The lid-driven cavity flow is a well-known benchmark problem for the validation of new numerical methods and techniques. In experimental and numerical studies with viscoelastic fluids in such lid-driven flows, purely-elastic instabilities have been shown to appear even at very low Reynolds numbers. In this work, a finite-volume viscoelastic code, using the log-conformation formulation, is used to probe the effect of viscoelasticity on the appearance of such instabilities in lid-driven cavities for a wide range of aspect ratios (0.125 ≤ Λ ≤ 4.0) at different Deborah number under creeping-flow conditions. The effect of the viscoelasticity on the steady-state results and on the critical conditions for the onset of the elastic instabilities are described and compared to experimental results.

description: A public release of slitless spectra, obtained with ACS/WFC and the G800L grism, is presented. Spectra were automatically extracted in a uniform way from 153 archival fields (or "associations") distributed across the two Galactic caps, covering all observations to 2008. The ACS G800L grism provides a wavelength range of 0.55-1.00 μ$m, with a dispersion of $40 \ Å/ pixel$ and a resolution of $\sim 80\ Å$ for point-like sources. The ACS G800L images and matched direct images were reduced with an automatic pipeline that handles all steps from archive retrieval, alignment and astrometric calibration, direct image combination, catalogue generation, spectral extraction and collection of metadata. The large number of extracted spectra (73,581) demanded automatic methods for quality control and an automated classification algorithm was trained on the visual inspection of several thousand spectra. The final sample of quality controlled spectra includes 47,919 datasets (65% of the total number of extracted spectra) for $32,149$ unique objects, with a median $i_{\rm AB}$-band magnitude of 23.7, reaching 26.5 AB for the faintest objects. Each released dataset contains science-ready 1D and 2D spectra, as well as multi-band image cutouts of corresponding sources and a useful preview page summarising the direct and slitless data, astrometric and photometric parameters. In order to characterize the slitless spectra, emission-line flux and equivalent width sensitivity of the ACS data were compared with public ground-based spectra in the GOODS-South field. An example list of emission line galaxies with two or more identified lines is also included, covering the redshift range $0.2-4.6$.

description: The effects of the hydration mechanism on continental crust recycling are analyzed through a 2D finite element thermo-mechanical model. Oceanic slab dehydration and consequent mantle wedge hydration are implemented using a dynamic method. Hydration is accomplished by lawsonite and serpentine breakdown; topography is treated as a free surface. Subduction rates of 1, 3, 5, 7.5 and 10 cm/y, slab angles of 30o, 45o and 60o and a mantle rheology represented by dry dunite and dry olivine flow laws, have been taken into account during successive numerical experiments. Model predictions pointed out that a direct relationship exists between mantle rheology and the amount of recycled crustal material: the larger the viscosity contrast between hydrated and dry mantle, the larger the percentage of recycled material into the mantle wedge. Slab dip variation has a moderate impact on the recycling. Metamorphic evolution of recycled material is influenced by subduction style. TPmax, generally representative of eclogite facies conditions, is sensitive to changes in slab dip. A direct relationship between subduction rate and exhumation rate results for different slab dips that does not depend on the used mantle flow law. Thermal regimes predicted by different numerical models are compared to PT paths followed by continental crustal slices involved in ancient and recent subduction zones, making ablative subduction a suitable pre-collisional mechanism for burial and exhumation of continental crust.

description: We study theoretically the groundstates of two-dimensional Bose-Hubbard models which are frustrated by gauge fields. Motivated by recent proposals for the implementation of optically induced gauge potentials, we focus on the situation in which the imposed gauge fields give rise to a pattern of staggered fluxes, of magnitude $α$ and alternating in sign along one of the principal axes. For $α=1/2$ this model is equivalent to the case of uniform flux per plaquette $n_ϕ=1/2$, which, in the hard-core limit, realizes the "fully frustrated" spin-1/2 XY model. We show that the mean-field groundstates of this frustrated Bose-Hubbard model typically break translational symmetry. We introduce a general numerical technique to detect broken symmetry condensates in exact diagonalization studies. Using this technique we show that, for all cases studied, the groundstate of the Bose-Hubbard model with staggered flux $α$ is condensed, and we obtain quantitative determinations of the condensate fraction. We discuss the experimental consequences of our results. In particular, we explain the meaning of gauge-invariance in ultracold atom systems subject to optically induced gauge potentials, and show how the ability to imprint phase patterns prior to expansion can allow very useful additional information to be extracted from expansion images.

description: Optical responses of graphene in the presence of intense circularly and linearly polarized terahertz fields are investigated based on the Floquet theory. We examine the energy spectrum and density of states. It is found that gaps open in the quasi-energy spectrum due to the single-photon/multi-photon resonances. These quasi-energy gaps are pronounced at small momentum, but decrease dramatically with the increase of momentum and finally tend to be closed when the momentum is large enough. Due to the contribution from the states at large momentum, the gaps in the density of states are effectively closed, in contrast to the prediction in the previous work by Oka and Aoki [Phys. Rev. B {\bf 79}, 081406(R) (2009)]. We also investigate the optical conductivity for different field strengths and Fermi energies, and show the main features of the dynamical Franz-Keldysh effect in graphene. It is discovered that the optical conductivity exhibits a multi-step-like structure due to the sideband-modulated optical transition. It is also shown that dips appear at frequencies being the integer numbers of the applied terahertz field frequency in the case of low Fermi energy, originating from the quasi-energy gaps at small momentums. Moreover, under a circularly polarized terahertz field, we predict peaks in the middle of the "steps" and peaks induced by the contribution from the states around zero momentum in the optical conductivity.

Genetic analysis of anp2/3-mkk6-mpk4 cascade in plant immunity
Creators: name: Lian, Kehui
Publisher: name: University of British Columbia
Year: 2018

description: Recognition of pathogens through pathogen-associated molecular patterns (PAMPs) or effectors in plants activates a variety of defense responses including MAPKs signaling pathways and defense related genes expression. ANPs (Arabidopsis Nucleus- and Phragmoplast- localized kinase 1 related protein kinases), including ANP1, ANP2, ANP3 are three MAP kinase kinase kinases that form a MAP kinase cascade with downstream MKK6 and MPK4 to regulate cytokinesis process. In this study, we showed that the anp2 anp3 double mutants exhibit constitutive expression of PR (Pathogenesis-Related) genes and enhanced resistance against oomycete pathogen H. a. Noco2, suggesting that ANP2 and ANP3 negatively regulate plant immunity. In addition, loss function of MKK6 causes high levels of PR gene expression, indicating that MKK6 is involved in negative regulation of defense responses. Since MPK4 was previously shown to function as a negative regulator of plant immunity, we tested whether MPK4 functions downstream of ANP2/ANP3 and MKK6 in plant immunity by introducing CA-MPK4 transgene, which expresses a constitutively active (CA) variant of MPK4, to anp2 anp3 and mkk6. Constitutive expression of PR genes and enhanced resistance to H.a. Noco2 in anp2 anp3 and mkk6 were partially suppressed by expressing CA MPK4, suggesting that the ANP2/ANP3, MKK6 and MPK4 function in a MAPK cascade to negatively regulate defense responses. To find out components that function downstream of ANP2/ANP3- MKK6-MPK4 cascade in plant immunity, two mutants summ2-8 (SUPPRESSOR OF MKK1 MKK2 2) and pad4-1 (PHYTOALEXIN DEFICIENT 4) were crossed into anp2 anp3 respectively. The constitutive defense responses in anp2 anp3 were fully suppressed by pad4-1, but not affected by the summ2-8 mutation, suggesting that PAD4 functions downstream of ANP2/ANP3 and that immune responses mediated by certain TIR-NB-LRR R proteins might be activated in the anp2 anp3 mutant.
Design of effective kernels for spectroscopy and molecular transport: time-dependent current-density-functional theory

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: Time-dependent current-density-functional theory (TDCDFT) provides an in principle exact scheme to calculate efficiently response functions for a very broad range of applications. However, the lack of approximations valid for a range of parameters met in experimental conditions has so far delayed its extensive use in inhomogeneous systems. On the other side, in many-body perturbation theory (MBPT) accurate approximations are available, but at a price of a higher computational cost. In the present work the possibility of combining the advantages of both approaches is exploited. In this way an exact equation for the exchange-correlation kernel of TDCDFT is obtained, which opens the way for a systematic improvement of the approximations adopted in practical applications. Finally, an approximate kernel for an efficient calculation of spectra of solids and molecular conductances is suggested and its validity discussed.
The effects of the overriding plate thermal state on the slab dip in an ocean-continent subduction system

description: To evaluate the effects of variations in the thermal state of the overriding plate on the slab dip in an ocean-continent subduction system, a 2-D finite element thermo-mechanical model was implemented. The lithosphere base was located at the depth of the 1600 K isotherm. Numerical simulations were performed while taking into account four different initial thicknesses for the oceanic lithosphere (60, 80, 95 and 110 km) and five different thicknesses of the overriding plate, as compared in terms of the continental-oceanic plate thickness ratio (100, 120, 140, 160 and 200% of the oceanic lithosphere thickness). The results of numerical modeling indicate that a high variability of the subducting plate geometry occurs for an oceanic lithosphere thickness ranging from 60 to 80 km, while the variability decreases where the oceanic plates are thicker (95 and 110 km). Furthermore, the slab dip strongly depends on the thermal state of the overriding plate, and, in particular, the slab dip decreases with the increase in the upper plate thickness. The model predictions also confirm that a direct correlation between the slab dip and the age of the oceanic lithosphere does not exist, at least for subduction plates thinner that 110 km. These conclusions are supported by the good agreement between the model results and the natural data referring to worldwide ocean-continent subduction zones.

Perturbative Aspects of Heterotically Deformed CP(N-1) Sigma Model. I

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this paper we begin the study of renormalizations in the heterotically deformed N=(0,2) CP(N-1) sigma models. In addition to the coupling constant g^2 of the undeformed N=(2,2) model, there is the second coupling constant γdescribing the strength of the heterotic deformation. We calculate both βfunctions, β_g and β_γat one loop, determining the flow of g^2 and γ. Under a certain choice of the initial conditions, the theory is asymptotically free. The βfunction for the ratio ρ=γ^2/g^2 exhibits an infrared fixed point at ρ={1}{2}. Formally this fixed point lies outside the validity of the one-loop approximation. We argue, however, that the fixed point at ρ={1}{2} may survive to all orders. The reason is the enhancement of symmetry - emergence of a chiral fermion flavor symmetry in the heterotically deformed Lagrangian - at ρ={1}{2}. Next we argue that β_ρformally obtained at one loop, is exact to all orders in the large-N (planar) approximation. Thus, the fixed point at ρ= {1}{2} is definitely the feature of the model in the large-N limit.

description: We present a systematic experimental and theoretical study of the two-phonon (2D) Raman scattering in graphene under uniaxial tension. The external perturbation unveils that the 2D mode excited with 785nm has a complex line-shape mainly due to the contribution of two distinct double resonance scattering processes (inner and outer) in the Raman signal. The splitting depends on the direction of the applied strain and the polarization of the incident light. The results give new insight into the nature of the 2D band and have significant implications for the use of graphene as reinforcement in composites since the 2D mode is crucial to assess how effectively graphene uptakes an applied stress or strain.

The robot designed for the competition had a vertical spinner driven by v-belts, a high-density polyethylene compliant outer armor ring, two independently driven wheels to allow zero-point turn capability, frame geometry that allowed the robot to be driven upside down, and an electrical system with two shut-off switches, one for the weapon and one for the drive system. Detailed in this report is an in-depth look at the design, manufacture, and testing of the project robot. After these sections are recommendations for changes to the design to make it more effective in the future.

description: A reliable explanation for the underlying mechanism responsible for the persistent aggregation and self-assembly of colloidal 5 nm diamond nanoparticles is critical to the development of nanodiamond-based technologies. Although a number of mechanisms have been proposed, validation has been hindered by the inherent difficulty associated with the identification and characterisation of the inter-particle interfaces. In this paper we present results of high resolution aberration corrected electron microscopy and complementary computer simulations to explicate the features involved, and confirm the electrostatic interaction mechanism as the most probable cause for the formation of agglutinates and agglomerates of primary particles.

description: In a recent paper, Leka at al. (Solar Phys. 260, 83, 2009)constructed a synthetic vector magnetogram representing a three-dimensional magnetic structure defined only within a fraction of an arcsec in height. They rebinned the magnetogram to simulate conditions of limited spatial resolution and then compared the results of various azimuth disambiguation methods on the resampled data. Methods relying on the physical calculation of potential and/or non-potential magnetic fields failed in nearly the same, extended parts of the field of view and Leka et al. (2009) attributed these failures to the limited spatial resolution. This study shows that the failure of these methods is not due to the limited spatial resolution but due to the narrowly defined test data. Such narrow magnetic structures are not realistic in the real Sun. Physics-based disambiguation methods, adapted for solar magnetic fields extending to infinity, are not designed to handle such data; hence, they could only fail this test. I demonstrate how an appropriate limited-resolution disambiguation test can be performed by constructing a synthetic vector magnetogram very similar to that of Leka et al. (2009) but representing a structure defined in the semi-infinite space above the solar photosphere. For this magnetogram I find that even a simple potential-field disambiguation method manages to resolve the ambiguity very successfully, regardless of limited spatial resolution. Therefore, despite the conclusions of Leka et al. (2009), a proper limited-spatial-resolution test of azimuth disambiguation methods is yet to be performed in order to identify the best ideas and algorithms.

Zusammenfassung

Um die Bedeutung der Kfz-bürtigen Platingruppenelemente (PGE)
Pt, Pd und Rh für die Bio-sphäre einschätzen zu können, wurde
die PGE-Akkumulation in Dreikantmuscheln mit der Anreicherung
anderer Schwermetalle verglichen. Der Konzentrationsfaktor (CF)
nahm in der Reihenfolge Cu > Zn > Cd > Ag > Pd > Pb > Sb > Fe >
Pt > Rh ab. Pd zeigte gegenüber dem essentiellen Metall Fe einen
um Faktor 10 höheren CF und übertraf das Anreicherungsvermögen
des ehemals Kfz-relevanten Pb. Die starke Aufnahme von Pd konnte
zudem durch experimentelle Arbeiten mit Barben demonstriert
werden. Das Ausmaß der PGE-Anreicherung ist entscheidend von
Wasserinhaltsstoffen abhängig. Sowohl EDTA als auch Huminstoffe
erhöhen durch Komplexbildung die Lipophilie der PGE und könnten
damit die Metallanreicherung in Organismen verstärken. Die
Bedeutung organischer PGE-Komplexe für die Akkumulation der
Metalle sowie die Sonderrolle von Pd werden diskutiert.

Summary

Accumulation of the traffic related platinum group elements
(PGE) Pt, Pd and Rh in the Zebra mussel was compared with that
of other common heavy metals. The concentration factors (CF)
decreased in the following order: Cu > Zn > Cd > Ag > Pd > Sb >
Pb > Fe > Pt > Rh. The CF of Pd was 10 times higher than that of
the essential element Fe and exceeded that of the former traffic
related Pb. A higher bioaccumulation of Pd compared with Pt and
Rh was also found in exposure studies using barbel. The degree
of PGE uptake depends on the presence of complexing agents in
the water. The lipid solubility of these metals was enhanced by
the presence of EDTA and humic substances. The significance of
organic PGE complexes and the hitherto unrecognized exceptional
position of Pd are discussed.

Holistic Modeling Approach for Enterprise Architecture
Creators: name: Fankhauser, Alexandra
Publisher: name: Zenodo
Year: 2023
Subjects: Enterprise Architecture
ArchiMate
e3-Value Method
BPMN 2.0
UML

description: The discipline of Enterprise Architecture has evolved over the past few years to become an important tool for organizations. Digitalization and the increasingly rapid pace of market change mean that companies must be able to adapt and reposition themselves quickly. In this context, it is essential to have an overview of one's own business and IT. There are already many established frameworks, modeling languages and tools on the market that professionals are familiar with. In order to get the most out of the architecture, this thesis has developed a method and a prototype for creating a holistic enterprise architecture. All sub-architectures according to TOGAF with the well-known state-of-the-art modeling languages ArchiMate, e3-Value, BPMN 2.0 and UML should be able to be mapped and connected in the same tool. The prototype is a good basis for mapping an enterprise architecture, whether in a company or for educational purposes. However, there are a number of improvements that have already been outlined in this paper and can be considered for further development.
Heterotic strings on G_2 orbifolds

Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study compactification of heterotic strings to three dimensions on orbifolds of G_2 holonomy. We consider the standard embedding and show that the gauge group is broken from E_8 x E_8 or SO(32) to F_4 x E_8 or SO(25) respectively. We also compute the spectrum of massless states and compare with the results obtained from reduction of the 10-dimensional fields. Non-standard embeddings are discussed briefly. For type II compactifications we verify that IIB and IIA have equal massless spectrum.

Quasistatic limit of the strong-field approximation describing atoms in intense laser fields: Circular polarization
Creators: name: Bauer, J. H.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: In the recent work of Vanne and Saenz [Phys. Rev. A 75, 063403 (2007)] the quasistatic limit of the velocity gauge strong-field approximation describing the ionization rate of atomic or molecular systems exposed to linearly polarized laser fields was derived. It was shown that in the low-frequency limit the ionization rate is proportional to the laser frequency (for a constant intensity of the laser field). In the present work I show that for circularly polarized laser fields the ionization rate is proportional to higher powers of the laser frequency for hydrogenic atoms. The new analytical expressions for asymptotic ionization rates (which become accurate in the quasistatic limit) contain no summations over multiphoton contributions. For very low laser frequencies (optical or infrared), these expressions usually remain with an order-of-magnitude agreement with the velocity gauge strong-field approximation.

Direct measurements of anisotropic energy transfers in a rotating turbulence experiment

description: We investigate experimentally the influence of a background rotation on the energy transfers in decaying grid turbulence. The anisotropic energy flux density, ${\bf F} ({\bf r}) = < δ{\bf u}\,(δ{\bf u})^2 >$, where $δ{\bf u}$ is the vector velocity increment over separation ${\bf r}$, is determined for the first time using Particle Image Velocimetry. We show that rotation induces an anisotropy of the energy flux $\nabla \cdot {\bf F}$, which leads to an anisotropy growth of the energy distribution $E({\bf r}) = < (δ{\bf u})^2 >$, in agreement with the Kármán-Howarth-Monin equation. Surprisingly, our results prove that this anisotropy growth is essentially driven by a nearly radial, but orientation-dependent, energy flux density ${\bf F} ({\bf r})$.

Developing mixture rules for non-conservative properties for pulp suspensions
Creators: name: Tsai, Pin Wen (Wendy)
Publisher: name: University of British Columbia
Year: 2016

description: Nowadays new technologies emerge constantly and people continuously strive to meet challenges. The Pulp and Paper industry has been faced with many changes in recent years. One of which is to diversify the fiber baskets to produce a wide range of products. To help papermakers to accommodate this transition from a single pulp component to a multi-component furnish used in their process, this paper first puts effort into developing a sound and effective methodology to characterize mixture rules that predict properties such as tensile strength and pulp freeness. Using an expansion of a higher order Taylor series as the backbone of model development and removing model parameters based on the limitation of the separately refined system and statistical analysis, the tensile strength and pulp freeness models give predictions close to the observed measurements within 10% variance. Furthermore, two methods, one being the minimization approach using least squares, and the other being the one variable approach, when granting more emphasis on one particular mixture parameter than the other is preferred, are established to determine the operating conditions required to satisfy multiple target properties. Lastly, a graphical user interface, built on the defined mixture models, is also constructed to make recommendations of the optimized condition that can be applied to generate a mixture to achieve both target properties at minimum cost.
Subdiffusion and intermittent dynamic fluctuations in the aging regime of concentrated hard spheres

description: We study the nonequilibrium aging dynamics in a system of quasi-hard spheres at large density by means of computer simulations. We find that, after a sudden quench to large density, the relaxation time initially increases exponentially with the age of the system. After a surprisingly large crossover time, the system enters the asymptotic aging regime characterized by a linear increase of the relaxation time with age. In this aging regime, single particle motion is strongly non-Fickian, with a mean-squared displacement increasing subdiffusively, associated to broad, non-Gaussian tails in the distribution of particle displacements. We find that the system ages through temporally intermittent relaxation events, and a detailed finite size analysis of these collective dynamic fluctuations reveals that these events are not spanning the entire system, but remain spatially localized.

Phase diagram for a Cubic Consistent-Q Interacting Boson Model Hamiltonian: signs of triaxiality

description: An extension of the Consistent-Q formalism for the Interacting Boson Model that includes the cubic QxQxQ term is proposed. The potential energy surface for the cubic quadrupole interaction is explicitly calculated within the coherent state formalism using the complete chi-dependent expression for the quadrupole operator. The Q-cubic term is found to depend on the asymmetry deformation parameter gamma as a linear combination of cos(3gamma) and cos^2(3γ) terms, thereby allowing for triaxiality. The phase diagram of the model in the large N limit is explored, it is described the order of the phase transition surfaces that define the phase diagram, and moreover, the possible nuclear equilibrium shapes are established. It is found that, contrary to expectations, there is only a very tiny region of triaxiality in the model, and that the transition from prolate to oblate shapes is so fast that, in most cases, the onset of triaxiality might go unnoticed.
