Exploring the Security Implications of Single Sign-On Deployments in the Wild
Creators: name: Ghasemisharif, Mohammad
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Web services face challenges with online identity and account management, especially in the face of security breaches and misuse. The rise of social media has led to the adoption of Single Sign-On (SSO) systems, allowing users to access multiple services using one identity provider (IdP) account, such as Facebook. While SSO systems offer users the convenience of accessing multiple services using credentials from trusted IdPs, they increase the attack surface and introduce new potential security vulnerabilities.
This dissertation explores the security ramifications of SSO in the context of web services. First, we unveil a set of novel SSO-driven attacks that can amplify account compromises, revealing that many services do not have adequate measures for account recovery post-compromise. In response, we introduce “Single Sign-Off”, a method to terminate access to all linked services if an IdP account is compromised. Next, motivated by our findings, we develop an automated framework, SAAT, which evaluates the SSO implementation in relying parties (RPs) at scale, uncovering a notable inconsistency in SSO maintenance and security measures. Our research further highlights the potential risks of combining SSO with conventional authentication methods, including the bypassing of two-factor authentication and CAPTCHAs, emphasizing new vulnerabilities that can jeopardize account security.

description: We present a major update to QuSpin, SciPostPhys.2.1.003 -- an open-source Python package for exact diagonalization and quantum dynamics of arbitrary boson, fermion and spin many-body systems, supporting the use of various (user-defined) symmetries in one and higher dimension and (imaginary) time evolution following a user-specified driving protocol. We explain how to use the new features of QuSpin using seven detailed examples of various complexity: (i) the transverse-field Ising chain and the Jordan-Wigner transformation, (ii) free particle systems: the Su-Schrieffer-Heeger (SSH) model, (iii) the many-body localized 1D Fermi-Hubbard model, (iv) the Bose-Hubbard model in a ladder geometry, (v) nonlinear (imaginary) time evolution and the Gross-Pitaevskii equation on a 1D lattice, (vi) integrability breaking and thermalizing dynamics in the translationally-invariant 2D transverse-field Ising model, and (vii) out-of-equilibrium Bose-Fermi mixtures. This easily accessible and user-friendly package can serve various purposes, including educational and cutting-edge experimental and theoretical research.

description: Mainstream Hindi cinema, or Bollywood, has often clustered female characters into a finite number of gendered tropes, from damsels in distress, Hindu goddesses, virtuous wives and mothers, to vamps, molls, vindictive mothers-in-law, and justice-seeking avengers. Recently, women-centric cinema has attempted to depart from such stereotypical portrayals, with movies such as Queen, Pink, and Tumhari Sulu. The present study investigates the nature of female rebellion in women-centric Bollywood movies from 2007 to 2017, delineated by a major act of rebellion undertaken by the female protagonist(s), the antecedents to the major act, the immediate reactions to, and the cinematic consequences of this act. Based on these criteria, four coders independently assessed 13 movies depicting rebellion in women-centric Bollywood movies. Quantitative analyses revealed a consistent story arc of rebellious depictions across movies. Qualitative analyses showed that major acts of rebellion occurred subsequent to negative antecedents such as disrespect, lack of freedom, abandonment, and inequality. Overall, the study contributes to understanding the contemporary portrayal of female rebellion in Bollywood.

description: The software architecture community would benefit from sharing a set of standard example problems. These would improve our ability to work out ideas, exhibit techniques, and compare results. The Software Architecture group at Carnegie Mellon has been assembling such a collection of problems. With this draft report we would like to open a discussion about suitable problems: what characteristics they should have, what specific problems would serve us well. To start that discussion, we present ten candidate problems and sketches of several distinct architectural approaches to two of them. We invite refinements and discussion of the problem list, the solution sets, and the criteria for choosing problems.

description: A new scheme for amplification of coherent gamma rays is proposed. The key elements are crystalline undulators - single crystals with periodically bent crystallographic planes exposed to a high energy beam of charged particles undergoing channeling inside the crystals. The scheme consists of two such crystals separated by a vacuum gap. The beam passes the crystals successively. The particles perform undulator motion inside the crystals following the periodic shape of the crystallographic planes. Gamma rays passing the crystals parallel to the beam get amplified due to interaction with the particles inside the crystals. The term `gamma klystron' is proposed for the scheme because its operational principles are similar to those of the optical klystron. A more simple one-crystal scheme is considered as well for the sake of comparison. It is shown that the gamma ray amplification in the klystron scheme can be reached at considerably lower particle densities than in the one-crystal scheme, provided that the gap between the crystals is sufficiently large.

description: This paper gives the first separation of quantum and classical pure (i.e., non-cryptographic) computing abilities with no restriction on the amount of available computing resources, by considering the exact solvability of a celebrated unsolvable problem in classical distributed computing, the ``leader election problem'' on anonymous networks. The goal of the leader election problem is to elect a unique leader from among distributed parties. The paper considers this problem for anonymous networks, in which each party has the same identifier. It is well-known that no classical algorithm can solve exactly (i.e., in bounded time without error) the leader election problem in anonymous networks, even if it is given the number of parties. This paper gives two quantum algorithms that, given the number of parties, can exactly solve the problem for any network topology in polynomial rounds and polynomial communication/time complexity with respect to the number of parties, when the parties are connected by quantum communication links.

description: We revisit the model by Wiser, Ribeck, and Lenski (Science \textbf{342} (2013), 1364--1367), which describes how the mean fitness increases over time due to beneficial mutations in Lenski's long-term evolution experiment. We develop the model further both conceptually and mathematically. Conceptually, we describe the experiment with the help of a Cannings model with mutation and selection, where the latter includes diminishing returns epistasis. The analysis sheds light on the growth dynamics within every single day and reveals a runtime effect, that is, the shortening of the daily growth period with increasing fitness; and it allows to clarify the contribution of epistasis to the mean fitness curve. Mathematically, we explain rigorous results in terms of a law of large numbers (in the limit of infinite population size and for a certain asymptotic parameter regime), and present approximations based on heuristics and supported by simulations for finite populations.

description: I review the microscopic spin-orbital Hamiltonian and ground state properties of spin one-half spinel oxides with threefold $t_{2g}$ orbital degeneracy. It is shown that for any orbital configuration a ground state of corresponding spin only Hamiltonian is infinitely degenerate in the classical limit. The extensive classical degeneracy is lifted by the quantum nature of the spins, an effect similar to order-out-of-disorder phenomenon by quantum fluctuations. This drives the system to a non-magnetic spin-singlet dimer manifold with a residual degeneracy due to relative orientation of dimers. The magneto-elastic mechanism of lifting the ``orientational'' degeneracy is also briefly reviewed.

description: Spherically imploding plasma liners, formed by merging hypersonic plasma jets, are a proposed standoff driver to compress magnetized target plasmas to fusion conditions [S. C. Hsu et al., IEEE Trans. Plasma Sci. 40, 1287 (2012)]. In this paper, the parameter space and physics criteria are identified for a subscale, plasma-liner-formation experiment to provide data, e.g., on liner ram-pressure scaling and uniformity, that are relevant for addressing scientific issues of full-scale plasma liners required to achieve fusion conditions. Based on these criteria, we quantitatively estimate the minimum liner kinetic energy and mass needed, which informed the design of a subscale plasma liner experiment now under development.

description: Despite all visible dividers, the Internet is getting us closer and closer, but with a great price. Our security is the price. The international community is fully aware of the urgent need to secure the cyberspace as you see the multiplication of security standards and national schemes interpreting them beyond borders: ISO 15408, ISO 17799, and ISO 27001. Even though some countries, including the Security Big Six (SB6), are equipped with their security books and may feel relatively safe; this remains a wrong sense of security as long as they share their networks with entities of less security. The standards impose security best practices and system specifications for the development of information security management systems. Partners beyond borders have to be secure as this is only possible if all entities connected to the partnership remain secure. Unfortunately, there is no way to verify the continuous security of partners without periodic security auditing and certification, and members who do not comply should be barred from the partnership. This concept also applies to the cyber space or the electronic society. In order to clean our society from cyber crimes and cyber terrorism we need to impose strict security policies and enforce them in a cooperative manner. The paper discusses a country's effort in the development of a national security strategy given its security economic intelligence position, its security readiness, and its adverse exposure.

description: This paper describes the use of the corotational cut Finite Element Method (FEM) for real-time surgical simulation. Users only need to provide a background mesh which is not necessarily conforming to the boundaries/interfaces of the simulated object. The details of the surface, which can be directly obtained from binary images, are taken into account by a multilevel embedding algorithm applied to elements of the background mesh that cut by the surface. Boundary conditions can be implicitly imposed on the surface using Lagrange multipliers. The implementation is verified by convergence studies with optimal rates. The algorithm is applied to various needle insertion simulations (e.g. for biopsy or brachytherapy) into brain and liver to verify the reliability of method, and numerical results show that the present method can make the discretisation independent from geometric description, and can avoid the complexity of mesh generation of complex geometries while retaining the accuracy of the standard FEM. Using the proposed approach is very suitable for real-time and patient specific simulations as it improves the simulation accuracy by taking into account automatically and properly the simulated geometry.

Old dog, new tricks : repurposing iron-carbide-carbonyl clusters as precursors for structural modeling of the nitrogenase cofactor

description: Nitrogenases are the only known biological enzyme capable of catalyzing the transformation of dinitrogen (N₂) into ammonia (NH₃). The active site of nitrogenase is comprised of a double-cuboidal iron-sulfur cluster featuring an interstitial carbide as the shared vertex, three ‘belt’ sulfides bridging the cuboidal components, and either a homocitrate-bearing heterometal (Mo, V) or an Fe at one of the distal capping metal sites. Out of the three nitrogenases, the Mo-dependent variant demonstrates the highest activity for N₂ conversion. The active-site cofactor of Mo-dependent nitrogenase (FeMoco) was first isolated in 1977; however, after decades of kinetic, structural, and spectroscopic research, many questions surrounding the mechanism of substrate reduction and the electronic structure of reaction intermediates remain unanswered. In this regard, the synthetic modelling community has contributed significantly towards directing mechanistic discussions with N₂-reducing functional model compounds. Furthermore, structural model compounds have played a pivotal role in deciphering the structural and electronic properties of FeMoco, including the identification of the central carbide and assignment of metal-site valence and spin states. Despite this remarkable progress, a synthetic model featuring a paramagnetic iron cluster with sulfides, interstitial carbide, and heterometal Mo has yet to be reported. The work relayed in this dissertation outlines our efforts towards pursuing this synthetic goal. As such, we utilize a family of carbonyl-supported iron clusters — first reported in the 1960s — featuring iron-coordinated inorganic carbide. However, the highly symmetric packing structures have made heterometal-containing carbidocarbonyl iron clusters difficult to unambiguously characterize by X-ray crystallography. Moreover, the strongly π-acidic ligation sphere enforces low metal-valance states and overall diamagnetism, and ligand substitution of COs is difficult to control. Here, we demonstrate a strategy to disrupt the symmetry in molybdenum-containing heteroclusters to unambiguously characterize the Mo site in XRD. Additionally, CO→S ligand substitution is achieved with the utilization of electrophilic sulfur sources, leading to progressively higher oxidation state Fe sites. These synthetic approaches for heterometal incorporation and oxidative sulfur insertion will serve as fundamental stepping-stones towards future endeavors in utilizing and functionalizing carbidocarbonyl iron clusters as synthetic precursors and ultimately, in biomimetically modeling the nitrogenase active site cluster.

description: A common class of existing information retrieval system provides access to abstracts. For example Stanford University, through its FOLIO system, provides access to the INSPEC database of abstracts of the literature on physics, computer science, electrical engineering, etc. In this paper this database is studied by using a trace-driven simulation. We focus on physical index design, inverted index caching, and database scaling in a distributed shared-nothing system. All three issues are shown to have a strong effect on response time and throughput. Database scaling is explored in two ways. One way assumes an ``optimal'' configuration for a single host and then linearly scales the database by duplicating the host architecture as needed. The second way determines the optimal number of hosts given a fixed database size.
Experimental and theoretical investigation of electrochemically synthesized AuPt dendrimer-encapsulated nanoparticles (DENs)

description: Herein, experiment and theory are combined to study the efficacy of synthesizing core@shell Au@Pt dendrimer-encapsulated nanoparticles (DENs) through electrochemical means. DENs are small (~1-2 nm), catalytically active nanoparticles (NPs) with precise sizes and compositions. These features assist pairing experiment with theory and catalytic interpretation. The small sizes of DENs can impart interesting physical and chemical properties that differ from bulk phase materials. Core@Pt shell NPs with monolayer (ML)-thick shells minimize the use of Pt, which is a key catalyst for various reactions but is expensive and scarce. Owing to the fact that the available techniques for Pt ML deposition were originally developed for bulk Au, their applicability to ~1.6 nm Au DEN cores is not trivial. In this dissertation, we explore several electrochemical strategies for synthesizing Au@Pt DENS: hydride-terminated (HT) Pt electrodeposition and underpotential deposition, followed by galvanic exchange with Pt (UPD/Pt GE) using two different UPD metals (Cu and Pb). Each of these techniques deposits a single Pt ML onto bulk Au surfaces. However, when they are applied to ~1.6 nm Au DENs, the AuPt NP structures that form are both dissimilar to one another and to the corresponding structures for bulk Au. The HT synthesis is found to lead to an alloy structure, whereas AuPt NP structure formed upon UPD/Pt GE depends on the choice of the UPD metal (Cu or Pb). More specifically, Cu UPD/Pt GE produces a core@shell structure, whereas an alloy structure is afforded by Pb UPD/Pt GE. These conclusions are supported by extensive experimental characterization and density functional theory (DFT) calculations. For the HT method, a core@shell structure can ultimately be obtained, but requires 3-5 total HT pulses. Due to the fact that catalysis tends to be highly structure sensitive, the results of these studies are important for rational design of catalysts. Indeed, we show that varying the number of HT pulses (from 1-10) can be used to tune electrocatalysis for formic acid oxidation (FAO).

description: Many complex biological, social, and economical networks show topologies drastically differing from random graphs. But, what is a complex network, i.e.\ how can one quantify the complexity of a graph? Here the Offdiagonal Complexity (OdC), a new, and computationally cheap, measure of complexity is defined, based on the node-node link cross-distribution, whose nondiagonal elements characterize the graph structure beyond link distribution, cluster coefficient and average path length. The OdC apporach is applied to the {\sl Helicobacter pylori} protein interaction network and randomly rewired surrogates thereof. In addition, OdC is used to characterize the spatial complexity of cell aggregates. We investigate the earliest embryo development states of Caenorhabditis elegans. The development states of the premorphogenetic phase are represented by symmetric binary-valued cell connection matrices with dimension growing from 4 to 385. These matrices can be interpreted as adjacency matrix of an undirected graph, or network. The OdC approach allows to describe quantitatively the complexity of the cell aggregate geometry.

description: Superlubricity, or alternatively termed structural (super)lubrictiy, is a concept where ultra-low friction is expected at the interface between sliding surfaces if these surfaces are incommensurate and thus unable to interlock. In this work, we now report on sudden, reversible, friction changes that have been observed during AFM based nanomanipulation experiments of gold nanoparticles sliding on highly oriented pyrolythic graphite. These effects are can be explained by rotations of the gold nanoparticles within the concept of structural superlubricity, where the occurrence of ultra-low friction can depend extremely sensitively on the relative orientation between the slider and the substrate. From our theoretical simulations it will become apparent how even miniscule magnitudes of rotation are compatible to the observed effects and how size and shape of the particles can influence the dependence between friction and relative orientation.

description: We consider some of Jonathan and Peter Borweins' contributions to the high-precision computation of $π$ and the elementary functions, with particular reference to their book "Pi and the AGM" (Wiley, 1987). Here "AGM" is the arithmetic-geometric mean of Gauss and Legendre. Because the AGM converges quadratically, it can be combined with fast multiplication algorithms to give fast algorithms for the $n$-bit computation of $π$, and more generally the elementary functions. These algorithms run in almost linear time $O(M(n)\log n)$, where $M(n)$ is the time for $n$-bit multiplication. We outline some of the results and algorithms given in Pi and the AGM, and present some related (but new) results. In particular, we improve the published error bounds for some quadratically and quartically convergent algorithms for $π$, such as the Gauss-Legendre algorithm. We show that an iteration of the Borwein-Borwein quartic algorithm for $π$ is equivalent to two iterations of the Gauss-Legendre quadratic algorithm for $π$, in the sense that they produce exactly the same sequence of approximations to $π$ if performed using exact arithmetic.

description: The chromosphere of the quiet Sun is a highly intermittent and dynamic phenomenon. Three-dimensional radiation (magneto-)hydrodynamic simulations exhibit a mesh-like pattern of hot shock fronts and cool expanding post-shock regions in the sub-canopy part of the inter-network. This domain might be called "fluctosphere". The pattern is produced by propagating shock waves, which are excited at the top of the convection zone and in the photospheric overshoot layer. New high-resolution observations reveal a ubiquitous small-scale pattern of bright structures and dark regions in-between. Although it qualitatively resembles the picture seen in models, more observations - e.g. with the future ALMA - are needed for thorough comparisons with present and future models. Quantitative comparisons demand for synthetic intensity maps and spectra for the three-dimensional (magneto-)hydrodynamic simulations. The necessary radiative transfer calculations, which have to take into account deviations from local thermodynamic equilibrium, are computationally very involved so that no reliable results have been produced so far. Until this task becomes feasible, we have to rely on careful qualitative comparisons of simulations and observations. Here we discuss what effects have to be considered for such a comparison. Nevertheless we are now on the verge of assembling a comprehensive picture of the solar chromosphere in inter-network regions as dynamic interplay of shock waves and structuring and guiding magnetic fields.

description: We consider a variant of the Boolean satisfiability problem where a subset E of the propositional variables appearing in formula F sat encode a symmetric, transitive, binary relation over N elements. Each of these relational variables, e, i, j, for 1, expresses whether or not the relation holds between elements i and j. The task is to either find a satisfying assignment to F sat that also satisfies all transitivity constraints over the relational variables (e.g., e 1,2 ^ e 2,3 --> e 1,3), or to prove that no such assignment exists. Solving this satisfiability problem is the final and most difficult step in our decision procedure for a logic of equality with uninterpreted functions. This procedure forms the core of our tool for verifying pipelined microprocessors. To use a conventional Boolean satisfiability checker,we augment the set of clauses expressing F sat with clauses expressing the transitivity constraints. We consider methods to reduce the number of such clauses based on the sparse structure of the relational variables. To use Ordered Binary Decision Diagrams (OBDDs), we show that for some sets E , the OBDD representation of the transitivity constraints has exponential size for all possible variable orderings. By considering only those relational variables that occur in the OBDD representation of F sat, our experiments show that we can readily construct an OBDD representation of the relevant transitivity constraints and thus solve the constrained satisfiability problem.
Engineered Platforms for iPSC-Derived Human Hepatocyte Differentiation and HBV Infection

description: Hepatitis B virus (HBV) is a global disease and accounts for 80% of virus-related hepatocellular carcinoma. Conducting drug tests on chimpanzees (the only natural animal model of HBV) is prohibitively expensive and severely restricted. Thus, in vitro human liver platforms are urgently needed for HBV studies. Shortages of donor livers and donor-donor variability prevent primary human hepatocytes (PHHs) use for high-throughput drug screening. In contrast, induced pluripotent stem cell (iPSC)-derived human hepatocyte-like cells (HLCs) provide a nearly infinite cell resource with donor-personalized genetic background; therefore, HLCs are an alternative cell source to PHHs to study HBV. However, the current limitations of HLCs are a fetal-like phenotype and exorbitant expenses for large-scale production. Extracellular matrix (ECM) is essential to affect cell functions and guide cell fate through ECM-cell interactions. Electrospun nanofibers mimic ECM topography and stiffness and contain major ECM proteins that have been shown to support PHH functionality in vitro. Thus, the first goal of this thesis is to utilize natural ECM nanofibers to mature HLCs and investigate the roles of topography and stiffness on HLC differentiation. Currently, cutting-edge gene editing technologies allow dynamic and precise cell differentiation and maturation modulation. The second goal of this thesis is to identify key transcription factors (TFs) crucial to modulating HLC differentiation by integrated RNA sequencing and ATAC sequencing analysis. Overexpression or depression of these genes impacts hepatic gene activation and subsequent hepatocyte development. Moreover, TFs and TF-TF networks relevant to the essential hepatic pathways were also explored to improve hepatic function and maturation. In addition to ECM manipulation and gene editing, coculture with stromal cells is beneficial for cell differentiation and development due to paracrine secretions and cell-cell interactions. Previously, the micropatterned coculture (iMPCC) supported higher hepatic functions of HLCs with fibroblasts over 4 weeks. Thus, the third goal of this thesis is to optimize HBV infection in iMPCC by adding small molecules such as cyclic adenosine monophosphate (cAMP) and Janus-kinase inhibitor (JAKi) and then utilize the HBV-infected iMPCC to investigate HBV infection and screen antiviral drugs.

description: We study the conservative dynamics and stationary configurations of a vortex-antivortex pair in a harmonically trapped two-dimensional Bose-Einstein condensate. We establish the conceptual framework for understanding the stationary states and the topological defect trajectories, through considerations of different mechanisms of vortex motion and the bifurcation of soliton-like stationary solutions. Our insights are based on Lagrangian-based variational calculations, numerical solutions of both the time-dependent and time-independent Gross-Pitaevskii equations, and exact solutions for the non-interacting case.

description: I dynamically evolve spherically symmetric spacetimes containing gravitational 't Hooft-Polyakov monopoles and determine the stable end states of the evolutions. I do so to study stability and critical behavior of the well-known static gravitational monopole solutions. For the static solutions, there exist regions of parameter space where two static monopole black holes and the static Reissner-Nordstrom black hole have the same mass. I find strong evidence that one of the static monopole black hole solutions is a critical solution, to which near-critical solutions are dynamically attracted before evolving to one of the other two static solutions as end states. I also discuss the no-hair conjecture for this model in the context of collapse.

description: This paper presents a method for hyperspectral image classification that uses support vector data description (SVDD) with the Gaussian kernel function. SVDD has been a popular machine learning technique for single-class classification, but selecting the proper Gaussian kernel bandwidth to achieve the best classification performance is always a challenging problem. This paper proposes a new automatic, unsupervised Gaussian kernel bandwidth selection approach which is used with a multiclass SVDD classification scheme. The performance of the multiclass SVDD classification scheme is evaluated on three frequently used hyperspectral data sets, and preliminary results show that the proposed method can achieve better performance than published results on these data sets.

description: Biological systems consist of complex and highly dynamic networks of molecular processes carried out by the enzymes. About one third of the enzymes need a metal cofactor for their activity, and hence, are called as metalloenzymes. One such metalloenzyme is carbonic anhydrase (CA), a Zn²⁺ containing protein, that catalyzes the reversible hydration of carbon dioxide, thereby playing an important role in acid base homeostasis. There are multiple isoforms of CA and their activity, localization, and expression level vary in different cell types and also differ between normal and disease states. CA is known to be overexpressed in hypoxia, which leads to the greater pH imbalance providing a positive pathway for the cancerous tumors to metastasize. Therefore, it is imperative to get precise on-demand control over these isoforms without perturbing the whole system in order to understand their role in biological systems, especially in the therapeutic context. Light serves as a wonderful external trigger due to these advantages: non-invasive; easy to control the wavelength, duration, and intensity of light; and exhibits high spatiotemporal precision. My doctoral research focuses on developing photopharmacophores for light mediated control of CA in in vitro and in vivo systems. We designed carbonic anhydrase azobenzene photoswitch (CAP-1) that can isomerize between two isomeric forms, trans and cis. This probe contains a metal binding group which interacts with the Zn²⁺ in the active site only in trans form, hence, inhibiting the protein activity. We further tuned the design with photoswitch CAP-5, which allowed the visible light mediated bidirectional control over CA in an isolated protein, intact live cells, and in vivo with zebrafish during embryo development. Additionally, we explored the prospect of photoregulation of a specific membrane-associated isoform of CA (CAIX) by modifying CAP-F5 to confine the probe to extracellular matrix. Correspondingly, we used the photoremovable protecting group (PPG) to achieve spatiotemporal control over the mitochondrial isoform of carbonic anhydrase (CAV). The probe PCE-M consists of three parts: inhibitor, PPG and a mitochondrial-directing group. The photocleaving process is triggered with 410 nm light to get free inhibitor that can inhibit CAV without interference from other isoforms of CA.

description: We study the entanglement entropy of the quantum trajectories of a free fermion chain under continuous monitoring of local occupation numbers. We propose a simple theory for entanglement entropy evolution from disentangled and highly excited initial states. It is based on generalized hydrodynamics and the quasi-particle pair approach to entanglement in integrable systems. We test several quantitative predictions of the theory against extensive numerics and find good agreement. In particular, the volume law entanglement is destroyed by the presence of arbitrarily weak measurement.
