description: Quantum annealing is a generic solver for combinatorial optimization problems that utilizes quantum fluctuations. Recently, there has been extensive research applying quantum annealers, which are hardware implementations of quantum annealing. Since quantum annealers can only handle quadratic unconstrained binary optimization problems, to solve constrained combinatorial optimization problems using quantum annealers, the constraints must be incorporated into the objective function. One such technique is the Ohzeki method, which employs a Hubbard-Stratonovich transformation to relax equality constraints, and its effectiveness for large-scale problems has been demonstrated numerically. This study applies the Ohzeki method to combinatorial optimization problems with inequality constraints. We show that inequality constraints can be relaxed into a similar objective function through statistical mechanics calculations similar to those for equality constraints. In addition, we evaluate the performance of this method in a typical inequality-constrained combinatorial optimization problem, the quadratic knapsack problem.

description: Restart is a common strategy observed in nature that accelerates first-passage processes and has been extensively studied using classical random walks. In the quantum regime, restart in continuous-time quantum walks (CTQWs) has been shown to expedite the quantum hitting times. Here, we study how restarting monitored discrete-time quantum walks (DTQWs) affects the quantum hitting times. We show that the restarted DTQWs outperform classical random walks in target searches, benefiting from quantum ballistic propagation, a feature shared with their continuous-time counterparts. Moreover, the explicit coin degree of freedom in DTQWs allows them to surpass even CTQWs in target detection without sacrificing any quantum advantage. Additionally, knowledge of the target's parity or position relative to the origin can be leveraged to tailor DTQWs for even faster searches. Our study paves the way for more efficient use of DTQWs in quantum-walk-based search algorithms, simulations and modeling of quantum transport towards targeted sites in complex quantum networks.

description: Estimating decay parameters in lattice simulations is a computationally demanding problem, requiring several volumes and momenta. We explore an alternative approach, where the transition amplitude can be extracted from the spectral decomposition of particular ratios built from correlation functions. This so-called ratio method has the advantage of not needing various irreducible representations or volumes, and it allows us to predict the decay width $Γ$ and the energy shift $ε$ of the spectrum directly. In this work, we apply this method to study the hadronic decay $ψ(3770)\to \bar{D}D$ on two CLS $N_\text{f}=2$ ensembles. This approach requires close to on-shell kinematics to work, and we employ twisted boundary conditions to precisely tune the on-shell point. Although our study is yet to approach the continuum limit, we find a value of $Γ$ fully compatible to the physical result, and $ε$ informs us by how much our spectrum would shift in a fully dynamical simulation. Besides lattice calculations, many analytical tools have been proposed to understand decay processes. A relatively simple, early example is the ${}^3P_0$ quark model, which provides a physical insight of the decay process.

Combining Squeezing and Transition Sensitivity Resources for Quantum Metrology by Asymmetric Non-Linear Rabi model
Creators: name: Ying, Zu-Jian
Publisher: name: arXiv
Year: 2024
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Squeezing and transition criticality are two main sensitivity resources for quantum metrology (QM), combination of them may yield an upgraded metrology protocol for higher upper bound of measurement precision (MP). We show that such a combination is feasible in light-matter interactions by a realizable asymmetric non-linear quantum Rabi model (QRM). Indeed, the non-linear coupling possesses a squeezing resource for diverging MP while the non-monotonous degeneracy lifting by the asymmetries induces an additional tunable transition which further enhances the MP by several orders, as demonstrated by the quantum Fisher information. Moreover, the protocol is immune from the problem of diverging preparation time of probe state that may hinder the conventional linear QRM in application of QM. This work establishes a paradigmatic case of combining different sensitivity resources to manipulate QM and maximize MP.

We derive a sufficient condition for cyclicity of non-finitary automorphisms in contracting discrete automata groups. In the profinite setting we prove that fractal profinite groups may be regarded as measure-preserving dynamical systems and derive a sufficient condition for the ergodicity and the mixing properties of these dynamical systems. Furthermore, we show that a Haar-random element in a super strongly fractal profinite group is hypercyclic almost surely as an application of Birkhoff's ergodic theorem for free semigroup actions.

These expressions due to Lindhard, Klimontovich and Silin are used to re-analyze the Casimir interaction between two thick conducting plates in the leading order at high temperatures (zero'th term of Matsubara series). Up to small corrections that we discuss, the results of the conventional Drude model are confirmed. The difference between longitudinal and transverse permittivities (or polarization tensors) yields the Landau (orbital) diamagnetism of the electron gas.

Using the local field formulation of the anomaly-induced effective action, we show that the regularities of the spacetime and the RSET dictate the appropriate vacuum state. Furthermore, through a case study under the horizonless Bardeen-type spacetime, we demonstrate that the preferred vacuum state is not the Boulware vacuum, but a nontrivial one with a different RSET profile.

Non-Perturbative Corrections to Charged Black Hole Evaporation

Year: 2024
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The recent work of Brown et al. (arXiv:2411.03447) demonstrated that the low-temperature evaporation rate of a large near-extremal charged black hole is significantly reduced from semiclassical expectations. The quantum corrections responsible for the deviation come from Schwarzian modes of an emergent Jackiw-Teitelboim gravity description of the near-horizon geometry of the black hole. Using a one-parameter family of non-perturbative Airy completions, we extend these results to incorporate non-perturbative effects. At large parameter value, the non-perturbative evaporation rate is even smaller than the perturbative JT gravity results. The disparity becomes especially pronounced at very low energies, where the non-perturbative neutral Hawking flux is suppressed by a double exponential in the entropy of the black hole, effectively stopping its evaporation until the next charged particle is emitted via the Schwinger effect. We also explore an alternative family of Bessel completions for which the non-perturbative energy flux exceeds the perturbative JT gravity prediction.

description: Genus Mackiella Keifer, 1939:147
Diagnosis. Mackielline mites with broad, thin frontal lobe of prodorsal shield covering medio-proximal part of palpcoxal bases; tibial solenidion φ present, prodorsal shield setae ve and sc directed anteriad or lateroanteriad; dorsal opisthosomal annuli thrice wider than ventral annuli, flattened, with a distinct pattern of prominent longitudinal ridges; ventral annuli convex and rising high on the sides to the lateral edges of dorsal annuli.
Type species. Mackiella phoenicis Keifer, 1939:147 –148, 159 (Fig. XLV)
Species included. M. phoenicis, Mackiella reclinata n. sp.
Remarks. The mite species Mackiella borasis Mohanasundaram, 1981 is herein excluded from the genus Mackiella (see details under subfamily Phytoptinae below).
Distribution and hosts. So far Mackiella mites have been recorded from North America (USA, Keifer 1939), South Africa (this paper) and Iraq (Mohamed & El-Haidari 1965) living on young leaves of Phoenix palms.
Remarks. Newkirk and Keifer (1975, p. 568) wrote that M. phoenicis is “widespread on coconut” and “undoubtedly occurring wherever the host grows” without providing a reference to a collecting record. Amrine and Stasny (1994, p. 224) mistakenly mentioned that the original name of Mackiella type species is “ nuciferae Keifer 1939 ” and that M. phoenicis was collected from Cocos nuciferae. This was repeated by Amrine et al. (2003, p. 19) who stated that this mite species is “widespread on Cocos nuciferae ”. Actually, Mackiella mites have never been recorded from coconut palms.

description: We propose a unified framework based on persistent homology (PH) to characterize both local and global structures in disordered systems. It can simultaneously generate local and global descriptors using the same algorithm and data structure, and has shown to be highly effective and interpretable in predicting particle rearrangements and classifying global phases. We also demonstrated that using a single variable enables a linear SVM to achieve nearly perfect three-phase classification. Inspired by this discovery, we define a non-parametric metric, the Separation Index (SI), which not only achieves this classification without sacrificing significant performance but also establishes a connection between particle environments and the global phase structure. Our methods provide an effective framework for understanding and analyzing the properties of disordered materials, with broad potential applications in materials science and even wider studies of complex systems.

description: A search is presented for rare decays of the Z and Higgs bosons to a photon and a J/$ψ$ or a $ψ$(2S) meson, with the charmonium state subsequentially decaying to a pair of muons. The data set corresponds to an integrated luminosity of 123 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector at the LHC. No evidence for branching fractions of these rare decay channels larger than predicted in the standard model is observed. Upper limits at 95% confidence level are set: $\mathcal{B}$(H $\to$ J/$ψγ$) $\lt$ 2.6 $\times$ 10$^{-4}$, $\mathcal{B}$(H $\to$ $ψ$(2S)$γ$) $\lt$ 9.9 $\times$ 10$^{-4}$, $\mathcal{B}$(Z $\to$ J/$ψγ$) $\lt$ 0.6 $\times$ 10$^{-6}$, and $\mathcal{B}$(Z $\to$ $ψ$(2S)$γ$) $\lt$ 1.3 $\times$ 10$^{-6}$. The ratio of the Higgs boson coupling modifiers $κ_\mathrm{c} / κ_γ$ is constrained to be in the interval ($-$157, $+$199) at 95% confidence level. Assuming $κ_γ= 1$, this interval becomes ($-$166, $+$208).

Unraveling Arithmetic in Large Language Models: The Role of Algebraic Structures

description: Large language models (LLMs) have demonstrated remarkable mathematical capabilities, largely driven by chain-of-thought (CoT) prompting, which decomposes complex reasoning into step-by-step solutions. This approach has enabled significant advancements, as evidenced by performance on benchmarks like GSM8K and MATH. However, the mechanisms underlying LLMs' ability to perform arithmetic in a single step of CoT remain poorly understood. Existing studies debate whether LLMs encode numerical values or rely on symbolic reasoning, while others explore attention and multi-layered processing in arithmetic tasks. In this work, we propose that LLMs learn arithmetic by capturing algebraic structures, such as commutativity and identity properties. Since these structures are observable through input-output relationships, they can generalize to unseen data. We empirically demonstrate that LLMs can learn algebraic structures using a custom dataset of arithmetic problems, as well as providing theoretical evidence showing that, under specific configurations of weights and biases, the transformer-based LLMs can generate embeddings that remain invariant to both permutations of input tokens and the presence of identity elements. Our findings indicate that leveraging algebraic structures can enhance the LLMs' arithmetic capabilities, offering insights into improving their arithmetic performance.

Incertae sedis. borasis Mohanasundaram, 1981
Previous assignment. Mackiella borasis Mohanasundaram, 1981
Host. Borassus flabellifer L. [Arecaceae]
Relation to host. In the folds of young tender leaves, symptom presence not recorded, probably absent or not apparent.
Distribution. Vriddhachalam, Tamil Nadu, INDIA.
Remarks. Mackiella borasis is mentioned in several previous publications (Amrine & Stasny 1994; Amrine et al. 2003; Navia 2007) but does not conform to the diagnosis of Mackiella. This species has a vermiform body, with subequal annuli which are not differentiated dorso-ventrally. It thus does not conform to the diagnosis of either Sierraphytoptinae or Mackiellini. Morphologically, and particularly in body shape, it is similar to phytoptine mites. Therefore, the species borasis should be transferred to one of the currently recognized phytoptine genera namely Oziella, Acathrix or Phytoptus (Chetverikov 2014a). Mites of these three genera differ in their external morphology, the anatomy of their internal genitalia and in their host-plant associations. Unfortunately, the species borasis was incompletely described and data on the internal genitalia is insufficient for precise analysis of this species. The type material of borasis is probably lost (Prof. K. Ramaraju [Tamil Nadu Agricultural University, Coimbatore, INDIA], pers. comm. 9 July 2013). Therefore, new material needs to be recollected from the type locality, and neotypes should be designated. Thus, the generic assignment of the species “ borasis ” remains uncertain.

description: We investigate the temperature-dependent deposition of nickelocene (NiCp$_2$) molecules on a single crystal Au(111) substrate, revealing distinct adsorption behaviors and structural formations. At low temperatures (4.2 K), individual NiCp$_2$ molecules adsorb on the herringbone elbows and step edges, forming ordered patterns as molecular coverage increases. However, at 77 K, the molecules dissociate, yielding two main fragments: NiCp fragments that are Ni atoms capped by cyclopentadienyl (Cp) rings, which preferentially adsorb at FCC hollow sites, and Cp radical fragments exhibiting strong substrate interactions. NiCp fragments self-assemble into one-dimensional (1-D) chains along the $\langle 1 1 \bar{2} \rangle$ directions, displaying higher protrusion in STM images. The strain and steric hindrance from the Cp protons induce chiral patterns within the chains, which are well-reproduced by our DFT simulations. In contrast, the Cp fragments maintain distances due to short-range repulsive forces and exhibit low diffusion barriers. Interestingly, the fragments are non-magnetic, as confirmed by both STM measurements and DFT calculations, in contrast to the magnetic signals from intact Nc molecules. In addition to linear chains, dimers of the Ni-Cp fragments form along the $\langle 1 \bar{1} 0\rangle$ directions, requiring gold adatoms for their creation. These results demonstrate the feasibility of constructing complex nanostructures based on metallocenes via on-surface synthesis, opening the possibility for realizing low-dimensional magnetic systems by selecting substrates that preserve the magnetic moment of the fragments.

description: We calculate the exact spectral function of a single impurity repulsively interacting with a bath of fermions in one-dimensional lattices, by deriving the explicit expression of the form factor for both regular Bethe states and the irregular spin-flip state and $η$-pairing state, based on the exactly solvable Lieb-Wu model. While at low impurity momentum $Q\sim0$ the spectral function is dominated by two power-law Fermi singularities, at large momentum we observe that the two singularities develop into two-sided distributions and eventually become anomalous Fermi singularities at the boundary of the Brillouin zone (i.e., $Q=\pmπ$), with the power-law tails extending towards low energy. Near the quarter filling of the Fermi bath, we also find two broad polaron peaks at large impurity momentum, collectively contributed by many excited many-body states with non-negligible form factors. Our exact results of those distinct features in one-dimensional Fermi polarons, which have no correspondences in two and three dimensions, could be readily probed in cold-atom laboratories by trapping highly imbalanced two-component fermionic atoms into one-dimensional optical lattices.

description: The pervasiveness of mobile apps in everyday life necessitates robust testing strategies to ensure quality and efficiency, especially through end-to-end usage-based tests for mobile apps' user interfaces (UIs). However, manually creating and maintaining such tests can be costly for developers. Since many apps share similar functionalities beneath diverse UIs, previous works have shown the possibility of transferring UI tests across different apps within the same domain, thereby eliminating the need for writing the tests manually. However, these methods have struggled to accommodate real-world variations, often facing limitations in scenarios where source and target apps are not very similar or fail to accurately transfer test oracles. This paper introduces an innovative technique, LLMigrate, which leverages Large Language Models (LLMs) to efficiently transfer usage-based UI tests across mobile apps. Our experimental evaluation shows LLMigrate can achieve a 97.5% success rate in automated test transfer, reducing the manual effort required to write tests from scratch by 91.1%. This represents an improvement of 9.1% in success rate and 38.2% in effort reduction compared to the best-performing prior technique, setting a new benchmark for automated test transfer.
Revisiting the fundamentals of competitiveness: A research agenda for a “social-centric” model. 2017/11

description: The objective of this paper is to “bring” the centrality of social factors into the study of competitiveness. It thus proposes a “social-centric” model of competitiveness built on three pillars: Political, social and business. Results underline the robustness of the proposed model. They also highlight the central role of – for example – gender equality, social cohesion and quality of life for competitiveness, when interacting with political and business factors. The paper concludes by suggesting a set of specific propositions about possible avenues for future research to better understand the interactions between social factors and competitiveness. (✳) (✳✳)

description: The use of Large Language Models (LLMs) has increased significantly with users frequently asking questions to chatbots. In the time when information is readily accessible, it is crucial to stimulate and preserve human cognitive abilities and maintain strong reasoning skills. This paper addresses such challenges by promoting the use of hints as an alternative or a supplement to direct answers. We first introduce a manually constructed hint dataset, WikiHint, which is based on Wikipedia and includes 5,000 hints created for 1,000 questions. We then finetune open-source LLMs for hint generation in answer-aware and answer-agnostic contexts. We assess the effectiveness of the hints with human participants who answer questions with and without the aid of hints. Additionally, we introduce a lightweight evaluation method, HintRank, to evaluate and rank hints in both answer-aware and answer-agnostic settings. Our findings show that (a) the dataset helps generate more effective hints, (b) including answer information along with questions generally improves the quality of generated hints, and (c) encoder-based models perform better than decoder-based models in hint ranking.

description: The widespread adoption of smart meters for monitoring energy consumption has generated vast quantities of high-resolution time series data which remains underutilised. While clustering has emerged as a fundamental tool for mining smart meter time series (SMTS) data, selecting appropriate clustering methods remains challenging despite numerous comparative studies. These studies often rely on problematic methodologies and consider a limited scope of methods, frequently overlooking compelling methods from the broader time series clustering literature. Consequently, they struggle to provide dependable guidance for practitioners designing their own clustering approaches.
 This paper presents a comprehensive comparative framework for SMTS clustering methods using expert-informed synthetic datasets that emphasise peak consumption behaviours as fundamental cluster concepts. Using a phased methodology, we first evaluated 31 distance measures and 8 representation methods using leave-one-out classification, then examined the better-suited methods in combination with 11 clustering algorithms. We further assessed the robustness of these combinations to systematic changes in key dataset properties that affect clustering performance on real-world datasets, including cluster balance, noise, and the presence of outliers.
 Our results revealed that methods accommodating local temporal shifts while maintaining amplitude sensitivity, particularly Dynamic Time Warping and $k$-sliding distance, consistently outperformed traditional approaches. Among other key findings, we identified that when combined with $k$-medoids or hierarchical clustering using Ward's linkage, these methods exhibited consistent robustness across varying dataset characteristics without...

description: Coronary artery disease stands as one of the primary contributors to global mortality rates. The automated identification of coronary artery stenosis from X-ray images plays a critical role in the diagnostic process for coronary heart disease. This task is challenging due to the complex structure of coronary arteries, intrinsic noise in X-ray images, and the fact that stenotic coronary arteries appear narrow and blurred in X-ray angiographies. This study employs five different variants of the Mamba-based model and one variant of the Swin Transformer-based model, primarily based on the U-Net architecture, for the localization of stenosis in Coronary artery disease. Our best results showed an F1 score of 68.79% for the U-Mamba BOT model, representing an 11.8% improvement over the semi-supervised approach.

description: Semiconductor quantum dots offer a promising platform for controlling spin qubits and realizing quantum logic gates, essential for scalable quantum computing. In this work, we utilize a variational quantum compiling algorithm to design efficient three-qubit gates using a time-independent Hamiltonian composed of only physical interaction terms. The resulting gates, including the Toffoli and Fredkin gates, demonstrate high fidelity and robustness against both coherent and incoherent noise sources, including charge and nuclear spin noise. This method is applicable to a wide range of physical systems, such as superconducting qubits and trapped ions, paving the way for more resilient and universal quantum computing architectures.

title: Soziales Lernen bei Heliconius melpomene?
Creators: name: Riesenhuber, Sabine
Year: 2011

description: Bei dieser Diplomarbeit wurde getestet, ob es bei Schmetterlingen der Art Heliconius melpomene soziales Lernen gibt. Dazu wurden 4 Versuche mit jeweils mindestens 5 Durchgängen durchgeführt. Es wurde beobachtet, ob naive Tiere inAnwesenheit erfahrener Tiere schneller lernen, dass die Lantana-Pflanze ihre Nahrungsquelle ist und Nektar zu saugen beginnen. Bei Versuch 1 wurden naive Tiere, bei Versuch 2 erfahrene, bei Versuch 3 naive und erfahren Tiere zusammen und bei Versuch 4 naive und aufgesteckte, präparierte Tiere genommen. Es wurde bei jedem Durchgang die Zeit gestoppt und notiert, wie lange die einzelnen Schmetterlinge brauchen, bis sie an einer Blüte der Lantana-Pflanzen Nektar zu saugen beginnen. Aus den gewonnenen Beobachtungen wurde die 1. Gesamtanzahl der Versuchstiere, 2. Anzahl der nektarsaugenden Tiere, 3. Prozentanteil der nektarsaugenden Tiere (Nektarsaugquote), 4. Medianwert der gemessenen Zeiten und 5. Signifikanz der Testergebnisse mit dem Mann Whitney U-Test (p < 0,05) ermittelt. Es konnte nicht nachgewiesen werden, dass bei Heliconius melpomene soziales Lernen vorhanden ist. Es sind keine signifikanten Unterschiede festzustellen. Es kann aber auch nicht ausgeschlossen werden, da es, wie in der Diskussion gezeigt wird, viele Faktoren gibt, die einen starken Einfluss auf die Versuchsergebnisse haben können.
description: The diploma thesis concentrates on finding out if there exists social learning of the butterfly species Heliconius melpomene. There have been 4 test series with at least 5 repetitions. The aim was to find out, if naive butterflies learn quicker what is their food plant when adult and experienced butterflies are present. This would be called social learning. Test 1 used only naive butterflies, test 2 used only experienced butterflies, for test 3 were taken naive and experienced butterflies together and for test 4 were taken naive and primed butterflies (which are pined on the plants). During every test the time was noted on which the butterflies begun sucking nectar. With the sampled data it was established the (1) total number of the butterflies; (2) number of butterflies which fed on nectar; (3) percentage of nectar sucking animals; (4) median value of the obtained times and (5) significance with the Mann Whitney U-Test (p < 0,05). The results showed that there is no indication for social learning in Heliconius melpomene. There was no significance difference between the separate results. After all it cannot be excluded because, as the discussion shows, there are many factors that can have a strong influence on the results of the test.
The relation of galaxies and dark matter haloes to the filamentary cosmic web

description: We use the Millennium Simulation to study the relation of galaxies and dark matter haloes to the cosmic web. We define the web as the unique, fully connected, percolating object with (unsmoothed) matter density everywhere exceeding 5.25 times the cosmic mean. This object contains 35\% of all cosmic mass but occupies only 0.62\% of all cosmic volume. It contains 26\% of dark matter haloes of mass $10^{11}M_\odot$, rising to 50\% at $10^{12.7}M_\odot$, and to $>90\%$ above $10^{14}M_\odot$. In contrast, it contains 45\% of all galaxies of stellar mass $10^{8.5}M_\odot$, rising to 50\% at $10^{10}M_\odot$, to 60\% at $10^{11}M_\odot$ and to 90\% at $10^{11.5}M_\odot$. This difference arises because a large fraction of all satellite and backsplash galaxies are part of the cosmic web. Indeed, more than 50\% of web galaxies are satellites for stellar masses below that of the Milky Way, rising to about 70\% below $10^{10}M_\odot$, whereas centrals substantially outnumber satellites in the non-web population at all stellar masses. As a result, web galaxies have systematically lower specific star-formation rates (sSFR's) than non-web galaxies. For the latter, the distributions of stellar mass and sSFR are almost independent of web distance. Furthermore, for both central and satellite galaxies, the sSFR distributions at given stellar mass are very similar in and outside the web, once differences in backsplash fraction are accounted for. For the galaxy formation model considered here, differences between web and non-web galaxy populations are almost entirely due to the difference in halo mass distribution between the two environments.
