  text: Persistent security challenges plague DevOps teams due to a deficiency in
    expertise regarding security tools and methods, as evidenced by frequent security
    incidents. Existing maturity models fail to adequately address the specific needs
    of DevOps teams. In response, this paper proposes "Security Belts," a novel maturity
    model inspired by martial arts ranking systems. This model aims to assist DevOps
    teams in enhancing their security capabilities by providing a structured approach,
    starting with fundamental activities and progressing to more advanced techniques.
    Drawing from the experiences of monitoring 21 teams, the paper presents lessons
    learned and offers actionable advice for refining maturity models tailored to
    software quality improvement.

  text: <jats:p>Abstract. Reducing the weight of vehicles can significantly lower
    the energy or fuel consumed and thus the emissions during operation. One possibility
    to assess this is the use of a property adapted multi-material systems containing
    high strength steel, light metals like aluminium or magnesium and fibre reinforced
    plastics. While expanding the number of materials used new challenges arise for
    the production and furthermore the joining technology to manufacture the vehicle
    made of the multi-material systems. One approach to overcome these challenges
    is to use innovative and adaptable joining techniques which allows the manufacturing
    of joints of different material combinations. Extensive research activities on
    the two stage thermo-mechanical joining process with adaptable joining elements
    was able to demonstrate the great potentials in terms of joining dissimilar materials
    with good strength. The previously kinematic and path-based fabrication of auxiliary
    joining elements is modified in this publication to a form-based approach with
    a perspective of establishing an efficient process chain using easily and cheaply
    available rods. Based on the new approach to produce the auxiliary joining elements,
    it can be demonstrated that a reproducible production of the geometry is possible
    for the investigated steel as well as aluminium material. </jats:p>

  text: Die Wandlungsfähigkeit einer Prozesskette erfordert Fügeverbindungen mit gezielt
    einstellbaren mechanischen, elektrischen, thermischen oder chemischen Eigenschaften.
    Dieser Beitrag beschreibt die Untersuchungen, inwiefern beim Clinchen zweier Bleche
    aus der ausscheidungshärtbaren Aluminiumlegierung EN AW-6014 bereits auf Basis
    der Prozessüberwachung des Kraft-Weg-Verlaufs bzw. des sich daraus ergebenden
    Energieeintrags auf die mechanischen und elektrischen Eigenschaften der Fügeverbindung
    geschlossen werden kann. An einer ausgewählten Fügeaufgabe werden im Stufenversuch
    die gegenseitigen Abhängigkeiten der einzelnen Einflussgrößen sowie des Wärmebehandlungszustands
    aufgezeigt. Dabei wird zwischen den Bindemechanismen Formschluss und Kraftschluss
    unterschieden. Die Formschlusskomponente wird anhand der geometrischen Kenngrößen
    wie Bodendicke, Halsdicke und Hinterschnitt in Mikroskopieuntersuchungen an Schliffbildern
    und den mechanischen Eigenschaften der Fügeverbindung untersucht, die im Scherzug-
    und Kopfzugversuch bestimmt werden. Dazu erfolgt zudem die Charakterisierung der
    Versagensbilder. Zur Quantifizierung der Kraftschlusskomponente der Fügeverbindung
    werden das Losbrechmoment im Torsionsversuch und der elektrische Widerstand mittels
    Vier-Leiter-Methode ermittelt und korreliert.

  text: Similar to bulk metal forming, clinch joining is characterised by large plastic
    deformations and a variety of different 3D stress states, including severe compression.
    However, inherent to plastic forming is the nucleation and growth of defects,
    whose detrimental effects on the material behaviour can be described by continuum
    damage models and eventually lead to material failure. As the damage evolution
    strongly depends on the stress state, a stress-state-dependent model is utilised
    to correctly track the accumulation. To formulate and parameterise this model,
    besides classical experiments, so-called modified punch tests are also integrated
    herein to enhance the calibration of the failure model by capturing a larger range
    of stress states and metal-forming-specific loading conditions. Moreover, when
    highly ductile materials are considered, such as the dual-phase steel HCT590X
    and the aluminium alloy EN AW-6014 T4 investigated here, strong necking and localisation
    might occur prior to fracture. This can alter the stress state and affect the
    actual strain at failure. This influence is captured by coupling plasticity and
    damage to incorporate the damage-induced softening effect. Its relative importance
    is shown by conducting inverse parameter identifications to determine damage and
    failure parameters for both mentioned ductile metals based on up to 12 different
    experiments.

  text: "The Polynomial-Time Hierarchy ($\\mathsf{PH}$) is a staple of classical\r\ncomplexity
    theory, with applications spanning randomized computation to circuit\r\nlower
    bounds to ''quantum advantage'' analyses for near-term quantum computers.\r\nQuantumly,
    however, despite the fact that at least \\emph{four} definitions of\r\nquantum
    $\\mathsf{PH}$ exist, it has been challenging to prove analogues for\r\nthese
    of even basic facts from $\\mathsf{PH}$. This work studies three\r\nquantum-verifier
    based generalizations of $\\mathsf{PH}$, two of which are from\r\n[Gharibian,
    Santha, Sikora, Sundaram, Yirka, 2022] and use classical strings\r\n($\\mathsf{QCPH}$)
    and quantum mixed states ($\\mathsf{QPH}$) as proofs, and one\r\nof which is new
    to this work, utilizing quantum pure states\r\n($\\mathsf{pureQPH}$) as proofs.
    We first resolve several open problems from\r\n[GSSSY22], including a collapse
    theorem and a Karp-Lipton theorem for\r\n$\\mathsf{QCPH}$. Then, for our new class
    $\\mathsf{pureQPH}$, we show one-sided\r\nerror reduction for $\\mathsf{pureQPH}$,
    as well as the first bounds relating\r\nthese quantum variants of $\\mathsf{PH}$,
    namely $\\mathsf{QCPH}\\subseteq\r\n\\mathsf{pureQPH} \\subseteq \\mathsf{EXP}^{\\mathsf{PP}}$."

  text: "What is the power of polynomial-time quantum computation with access to an
    NP\r\noracle? In this work, we focus on two fundamental tasks from the study of\r\nBoolean
    satisfiability (SAT) problems: search-to-decision reductions, and\r\napproximate
    counting. We first show that, in strong contrast to the classical\r\nsetting where
    a poly-time Turing machine requires $\\Theta(n)$ queries to an NP\r\noracle to
    compute a witness to a given SAT formula, quantumly $\\Theta(\\log n)$\r\nqueries
    suffice. We then show this is tight in the black-box model - any\r\nquantum algorithm
    with \"NP-like\" query access to a formula requires\r\n$\\Omega(\\log n)$ queries
    to extract a solution with constant probability.\r\nMoving to approximate counting
    of SAT solutions, by exploiting a quantum link\r\nbetween search-to-decision reductions
    and approximate counting, we show that\r\nexisting classical approximate counting
    algorithms are likely optimal. First,\r\nwe give a lower bound in the \"NP-like\"
    black-box query setting: Approximate\r\ncounting requires $\\Omega(\\log n)$ queries,
    even on a quantum computer. We then\r\ngive a \"white-box\" lower bound (i.e.
    where the input formula is not hidden in\r\nthe oracle) - if there exists a randomized
    poly-time classical or quantum\r\nalgorithm for approximate counting making $o(log
    n)$ NP queries, then\r\n$\\text{BPP}^{\\text{NP}[o(n)]}$ contains a $\\text{P}^{\\text{NP}}$-complete\r\nproblem
    if the algorithm is classical and $\\text{FBQP}^{\\text{NP}[o(n)]}$\r\ncontains
    an $\\text{FP}^{\\text{NP}}$-complete problem if the algorithm is\r\nquantum."

  text: "Quantum Max Cut (QMC), also known as the quantum anti-ferromagnetic\r\nHeisenberg
    model, is a QMA-complete problem relevant to quantum many-body\r\nphysics and
    computer science. Semidefinite programming relaxations have been\r\nfruitful in
    designing theoretical approximation algorithms for QMC, but are\r\ncomputationally
    expensive for systems beyond tens of qubits. We give a second\r\norder cone relaxation
    for QMC, which optimizes over the set of mutually\r\nconsistent three-qubit reduced
    density matrices. In combination with Pauli\r\nlevel-$1$ of the quantum Lasserre
    hierarchy, the relaxation achieves an\r\napproximation ratio of $0.526$ to the
    ground state energy. Our relaxation is\r\nsolvable on systems with hundreds of
    qubits and paves the way to\r\ncomputationally efficient lower and upper bounds
    on the ground state energy of\r\nlarge-scale quantum spin systems."

  text: 'When it comes to NP, its natural definition, its wide applicability across
    scientific disciplines, and its timeless relevance, the writing is on the wall:
    There can be only one. Quantum NP, on the other hand, is clearly the apple that
    fell far from the tree of NP. Two decades since the first definitions of quantum
    NP started rolling in, quantum complexity theorists face a stark reality: There''s
    QMA, QCMA, QMA1, QMA(2), StoqMA, and NQP. In this article aimed at a general theoretical
    computer science audience, I survey these various definitions of quantum NP, their
    strengths and weaknesses, and why most of them, for better or worse, actually
    appear to fit naturally into the complexity zoo.'
