description: Several quantities relevant to phenomenological studies of the mixing of neutral B mesons are computed on the lattice. Our main results are: f_{Bd} sqrt(B_{Bd})=206(28)(7) MeV, f_{Bs} sqrt(B_{Bs})/f_{Bd}sqrt(B_{Bd})=1.16(7). We also obtain the related quantities f_{Bs}sqrt(B{Bs})=237(18)(8) MeV, f_{Bd}= 174(22)(+7-0)(-4-0) MeV, f_{Bs}= 204(15)(+7-0)(+3-0) MeV, f_{Bs}/f_{Bd}=1.17(4)(+0-1), f_{Bd}/f_{Ds}=0.74(5). After combining our results with the experimental world average (Delta m_d), we predict (Delta m_s)=15.8(2.1)(3.3) ps^{-1}. We have also computed the relevant parameters for mixing of neutral D mesons which may be useful in some extensions of the Standard Model. All the quantities were obtained from a quenched simulation with a non-perturbatively improved Clover action at beta=6.2, corresponding to a lattice spacing 1/a=2.7(1) GeV, on a sample of 200 gauge-field configurations. A discussion of the main systematic errors is also presented.

description: Processes where $W$ and $Z$ bosons scatter into pairs of electroweak bosons $W$, $Z$, and Higgs, are sensitive probes of new physics in the electroweak sector. We study simplified models that describe typical scenarios of new physics and parameterize the range of possible LHC results between the Standard-Model prediction and unitarity limits. Extending the study beyond purely longitudinal scattering, we investigate the role of transversally polarized gauge bosons. Unitarity becomes an essential factor, and limits on parameters matched to the naive perturbative low-energy effective theory turn out to be necessarily model-dependent. We discuss the implications of our approach for the interpretation of LHC data on vector-boson scattering and Higgs-pair production.

The unification of the gauge coupling constants in the framework of the non-SUSY model is possible if the SO(10) symmetry is broken via Pati-Salam type symmetries.

Macroeconomic Effects of the Exchange Rate : A Non-linear Analysis
Creators: name: Kaliba, Danny
Publisher: name: University of Leicester
Year: 2024
Subjects: Uncategorized

description: The thesis employs non-linear econometric techniques to explore the relationships involving the exchange rate and selected macroeconomic variables, which are subjects of controversy. First, the thesis examines the relationship between globalisation and the exchange rate passthrough to domestic prices, using the panel smooth transition regression model and a sample of 16 African countries. The thesis establishes evidence suggesting a non-linear relationship between globalisation and the pass-through exists, and that globalisation causes a rise in the level of the pass-through. Additional evidence suggests that the influence of globalisation on the pass-through varies with exchange rate regimes, with globalisation causing the pass-through to decrease in fixed regimes and to increase in flexible regimes.
Secondly, the thesis investigates non-linearity, asymmetry, and J-curve effects in the relationship between the exchange rate and the trade balance of Zambia with its 17 trading partners. The thesis uses the logistic vector smooth transition regression model and the non-linear panel autoregressive distributed lag model for estimations. Evidence favouring non-linearity and asymmetry effects is established. However, limited evidence of J-curve is found, especially with individual trading partners. Evidence suggests that currency depreciation cannot be relied on to improve trade balance.
Third, the thesis examines the relationship between the exchange rate and foreign direct investments, taking into account the role of trade openness, natural resources, and institutional quality. Based on the estimation of the dynamic panel threshold model on a sample of 44 African countries, the thesis establishes evidence of non-linear effects. Specifically, the thesis finds that trade openness, natural resources, and institutional quality induce a non-linear response in foreign direct investments to their determinants. Furthermore, the thesis establishes new evidence suggesting that currency depreciation attracts FDI inflows in countries characterised by greater economic openness, abundant natural resources, and weaker institutions.
The findings of the thesis elicit important macroeconomic implications.
NLO BFKL Equation, Running Coupling and Renormalization Scales
Creators: name: Thorne, R. S.
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: I examine the solution of the BFKL equation with NLO corrections relevant for deep inelastic scattering. Particular emphasis is placed on the part played by the running of the coupling. It is shown that the solution factorizes into a part describing the evolution in Q^2, and a constant part describing the input distribution. The latter is infrared dominated, being described by a coupling which grows as x decreases, and thus being contaminated by infrared renormalons. Hence, for this part we agree with previous assertions that predictive power breaks down for small enough x at any Q^2. However, the former is ultraviolet dominated, being described by a coupling which falls like 1/(\ln(Q^2/Λ^2) + A(\barα_s(Q^2)\ln(1/x))^1/2)with decreasing x, and thus is perturbatively calculable at all x. Therefore, although the BFKL equation is unable to predict the input for a structure function for small x, it is able to predict its evolution in Q^2, as we would expect from the factorization theory. The evolution at small x has no true powerlike behaviour due to the fall of the coupling, but does have significant differences from that predicted from a standard NLO in alpha_s treatment. Application of the resummed splitting functions with the appropriate coupling constant to an analysis of data, i.e. a global fit, is very successful.

Mitigating algorithmic errors in Hamiltonian simulation

description: Quantum computers can efficiently simulate many-body systems. As a widely used Hamiltonian simulation tool, the Trotter-Suzuki scheme splits the evolution into the number of Trotter steps $N$ and approximates the evolution of each step by a product of exponentials of each individual term of the total Hamiltonian. The algorithmic error due to the approximation can be reduced by increasing $N$, which however requires a longer circuit and hence inevitably introduces more physical errors. In this work, we first study such a trade-off and numerically find the optimal number of Trotter steps $N_{\textrm{opt}}$ given a physical error model in a near-term quantum hardware. Practically, physical errors can be suppressed using recently proposed error mitigation methods. We then extend physical error mitigation methods to suppress the algorithmic error in Hamiltonian simulation. By exploiting the simulation results with different numbers of Trotter steps $N\le N_{\textrm{opt}}$, we can infer the exact simulation result within a higher accuracy and hence mitigate algorithmic errors. We numerically test our scheme with a five qubit system and show significant improvements in the simulation accuracy by applying both physical and algorithmic error mitigations.

description: This paper compares economic reforms in the two most populous economies of the world: China and India. While both China and India opted for a gradual approach to reforms, India had to begin with stabilization measures due to the fiscal and balance of payments crisis of 1991. Since Chinese reforms were initiated long before India's, the latter country could benefit by drawing relevant lessons from the former. Reforms are far from complete in either of the countries. In the case of China, further reforms need to concentrate on different issues such as social welfare, insurance, housing, state-owned enterprises, and the financial system. In India, continued reform actions are required in the areas of fiscal consolidation, openness of the economy, tax reforms, foreign investment policy, and the financial sector. In addition, reforms need to be initiated in areas such as exit policy, labor and land laws, decentralization of decision making power, and opening up of the insurance sector. The high growth experienced by the non-state sector in China could well be achieved by the private sector in India if it were to be extensively deregulated.

Inertial Theorem: Overcoming the quantum adiabatic limit

name: Kosloff, Ronnie
Publisher: name: arXiv
Year: 2018
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present a new theorem describing stable solutions for a driven quantum system. The theorem, coined `inertial theorem', is applicable for fast driving, provided the acceleration rate is small. The theorem states that in the inertial limit eigenoperators of the propagator remain invariant throughout the dynamics, accumulating dynamical and geometric phases. The proof of the theorem utilizes the structure of Liouville space and a closed Lie algebra of operators. We demonstrate applications of the theorem by studying three explicit solutions of a harmonic oscillator, a two-level and three-level system models. These examples demonstrate that the inertial solution is superior to that obtained with the adiabatic approximation. Inertial protocols can be combined to generate a new family of solutions. The inertial theorem is then employed to extend the validity of the Markovian Master equation to strongly driven open quantum systems. In addition, we explore the consequence of new geometric phases associated with the driving parameters.

description: Understanding the role of astrocytes in brain computation is a nascent challenge, promising immense rewards, in terms of new neurobiological knowledge that can be translated into artificial intelligence. In our ongoing effort to identify principles endow-ing the astrocyte with unique functions in brain computation, and translate them into neural-astrocytic networks (NANs), we propose a biophysically realistic model of an astrocyte that preserves the experimentally observed spatial allocation of its distinct subcellular compartments. We show how our model may encode, and modu-late, the extent of synchronous neural activity via calcium waves that propagate intracellularly across the astrocytic compartments. This relationship between neural activity and astrocytic calcium waves has long been speculated but it is still lacking a mechanistic explanation. Our model suggests an astrocytic "calcium cascade" mechanism for neuronal synchronization, which may empower NANs by imposing periodic neural modulation known to reduce coding errors. By expanding our notions of information processing in astrocytes, our work aims to solidify a computational role for non-neuronal cells and incorporate them into artificial networks.

Its slope as a function of the logarithm of disorder is compatible with newer RG-calculation results.

description: We consider the three-body mean motion resonance defined by the Jovian moons Io, Europa, and Ganymede, which is commonly known as the Laplace resonance. In particular, we construct approximate models for the evolution of the librating argument over the period of 100 years, focusing on its principal amplitude and frequency, and on the observed mean motion combinations associated with the quasi-resonant interactions. First, we numerically propagated the Cartesian equations of motion of the Jovian system for the period under examination, and by comparing the results with a suitable set of ephemerides, we derived the main dynamical effects on the target quantities. Using these effects, we built an alternative Hamiltonian formulation and used the normal forms theory to locate the resonance and to compute its main amplitude and frequency. From the Cartesian model we observe that on the timescale considered and with ephemerides as initial conditions, both the librating argument and the diagnostics are well approximated by considering the mutual gravitational interactions of Jupiter and the Galilean moons (including Callisto), and the effect of Jupiter's J2 harmonic. Under the same initial conditions, the Hamiltonian formulation in which Callisto and J2 are reduced to their secular contributions achieves larger errors for the quantities above, particularly for the librating argument. By introducing appropriate resonant variables, we show that these errors can be reduced by moving in a certain action-angle phase plane, which in turn implies the necessity of a tradeoff in the selection of the initial conditions. In addition to being a good starting point for a deeper understanding of the Laplace resonance, the models and methods described are easily generalizable to different types of multi-body mean motion resonances. They are also prime tools for studying the dynamics of extrasolar systems.

description: The recent suggestion that the entropy of Schwarzschild black holes can be computed in matrix theory using near-extremal D-brane thermodynamics is examined. It is found that the regime in which this approach is valid actually describes black strings stretched across the longitudinal direction, near the transition where black strings become unstable to the formation of black holes. It is argued that the appropriate dynamics on the other (black hole) side of the transition is that of the zero modes of the corresponding super Yang-Mills theory. A suggestive mean field theory argument is given for the entropy of black holes in all dimensions. Consequences of the analysis for matrix theory and the holographic principle are discussed.

description: Moral responsibility is a major concern in autonomous systems, with applications ranging from self-driving cars to kidney exchanges. Although there have been recent attempts to formalise responsibility and blame, among similar notions, the problem of learning within these formalisms has been unaddressed. From the viewpoint of such systems, the urgent questions are: (a) How can models of moral scenarios and blameworthiness be extracted and learnt automatically from data? (b) How can judgements be computed effectively and efficiently, given the split-second decision points faced by some systems? By building on constrained tractable probabilistic learning, we propose and implement a hybrid (between data-driven and rule-based methods) learning framework for inducing models of such scenarios automatically from data and reasoning tractably from them. We report on experiments that compare our system with human judgement in three illustrative domains: lung cancer staging, teamwork management, and trolley problems.

A deviation from general relativity (GR) in HL gravity can change typical features of the NS structure. In this study, we investigate the NS structure by deriving the Tolman-Oppenheimer-Volkoff equation in HL gravity. We find that a NS in HL gravity with a larger radius and heavier mass than a NS in GR remains stable without collapsing into a black hole.

description: We re-examine the effort to constrain the time-variability of the coupling constants of the fundamental interactions by studying the anomalous isotopic abundance of Sm observed at the remnants of the natural reactors which were in operation at Oklo about 2 billion years ago, in terms of a possible deviation of the resonance energy from the value observed today. We rely on new samples that were carefully collected to minimize natural contamination and also on a careful temperature estimate of the reactors. We obtain the upper bound $(-0.2\pm 0.8)\times 10^{-17}$ ${\rm y}^{-1}$ on the fractional rate of change of the electromagnetic as well as the strong interaction coupling constants. Our result basically agrees with and even suggests some improvement of the result due recently to Damour and Dyson. Strictly speaking, however, we find another range of the resonance energy shift indicating a nonzero time variation of the constants. We find a rather strong but still tentative indication that this range can be ruled out by including the Gd data, for which it is essential to take the effect of contamination into account.

description: The potential between two D4-branes at angles with partially unbroken supersymmetry is computed, and is used to discuss the creation of a fundamental string when two such D4-branes cross each other in M(atrix) theory. The effective Lagrangian is shown to be anomalous at 1-loop approximation, but it can be modified by bare Chern-Simons terms to preserve the invariance under the large gauge transformation. The resulting effective potential agrees with that obtained from the string calculations. The result shows that a fundamental string is created in order to cancel the repulsive force between two D4-branes at proper angles.

description: In this paper, we propose an enhanced CNN model for detecting supernovae (SNe). This is done by applying a new method for obtaining rotational invariance that exploits cyclic symmetry. In addition, we use a visualization approach, the layer-wise relevance propagation (LRP) method, which allows finding the relevant pixels in each image that contribute to discriminate between SN candidates and artifacts. We introduce a measure to assess quantitatively the effect of the rotational invariant methods on the LRP relevance heatmaps. This allows comparing the proposed method, CAP, with the original Deep-HiTS model. The results show that the enhanced method presents an augmented capacity for achieving rotational invariance with respect to the original model. An ensemble of CAP models obtained the best results so far on the HiTS dataset, reaching an average accuracy of 99.53%. The improvement over Deep-HiTS is significant both statistically and in practice.

description: Tomita-Takesaki modular theory provides a set of algebraic tools in quantum field theory that is suitable for the study of the information-theoretic properties of states. For every open set in spacetime and choice of two states, the modular theory defines a positive operator known as the relative modular operator that decreases monotonically under restriction to subregions. We study the consequences of this operator monotonicity inequality for correlation functions in quantum field theory. We do so by constructing a one-parameter Renyi family of information-theoretic measures from the relative modular operator that inherit monotonicity by construction and reduce to correlation functions in special cases. In the case of finite quantum systems, this Renyi family is the sandwiched Renyi divergence and we obtain a new simple proof of its monotonicity. Its monotonicity implies a class of constraints on correlation functions in quantum field theory, only a small set of which were known to us. We explore these inequalities for free fields and conformal field theory. We conjecture that the second null derivative of Renyi divergence is non-negative which is a generalization of the quantum null energy condition to the Renyi family.

description: Nowadays, the Gogny force is a referent in the theoretical description of nuclear structure phenomena. Its phenomenological character manifests in a simple analytical form that allows for implementations of techniques both at the mean field and beyond all over the nuclide chart. Over the years, multiple applications of the standard many-body techniques in an assorted set of nuclear structure applications have produced results which are in a rather good agreement with experimental data. The agreement allows for a simple interpretation of those intriguing phenomena in simple terms and gives confidence on the predictability of the interaction. The present status on the implementation of different many body techniques with the Gogny force is reviewed with a special emphasis on symmetry restoration and large amplitude collective motion.

Data, Decisions, and Doubt: Affording Trust Within Environmental Data Science
Creators: name: Thornton, Lauren
Publisher: name: Lancaster University
Year: 2025

description: Trust is recognised as a valuable element of socio-technical systems,
 facilitating numerous important benefits. Yet despite extensive study
 within and across multiple disciplines, achieving well-placed trust
 remains a perpetual challenge. This research explores the perception of
 trust within environmental data science: transdisciplinary, collaborative
 scientific research responding to fundamentally complex, global problems
 through data science methodologies and techniques. In this context, the
 presence of trust can reduce uncertainty and friction, consequently
 facilitating collaboration, generating robust scientific results, and
 supporting the reuse of data and models. To begin, this research
 undertakes a theoretical analysis of trust, deconstructing the typical
 foci of research – models of trust – arguing instead for a different
 modality: trust affordances. Trust affordances account for trust within
 system design by attending to multiple stakeholders arriving at trust from
 varying angles. As a concept, trust affordances are characteristics of the
 technology by virtue of itself or of features designed into the technology
 to promote trust by providing access to evidence of (dis)trustworthiness
 specific to a user, a technology, and their context.

 This work concentrates on the perceptions of stakeholders across the data
 science pipeline within two cases. In the first, six interviews and a
 workshop attended by seventeen participants are used to consider the
 perceptions of trust and trustworthiness by data curators within a
 Research Council. In the second case, thirteen interviews are undertaken
 and a survey of ten respondents are used to generate the views of data
 producers and consumers related to a Centre of Excellence. The empirical
 data is analysed twice to respectively produce general themes related to
 trust and instances of trust affordances. This research contends that
 whilst there is no universal answer or one-size-fits-all approach to
 trust, system designers can actively design for trust by embracing nuance
 and complexity with a creative, thorough, and thoughtful approach.

description: In today’s English language classrooms, technology keeps important to support language learning. However, the present research focuses only on the tools, i.e., Smart Boards, tablets/laptops, and Moodle (online learning management system). Modern English language teachers utilize English Preparatory School, BS, and Master in the Turkish Republic of Northern Cyprus (TRNC). Moreover, the present qualitative and observational research examines the role of technology utilized at the English Preparatory School in Cyprus International University to teach English to the learners who learn English as a Second Language. For the present research, data are collected through two interviews from the teachers who teach at Cyprus International University (CIU) and from an in-depth literature review. Through the findings, the researchers observe that: a) all the teachers in TRNC utilize technology, i.e., Smart Boards, tablets, and Moodle; b) technology helps the English Language Learners (ELLs) to enhance their language skills; c) teachers and students who utilize technology in language learning process face technical challenges due to lack of knowledge or less familiarity with the technology. Hence, the present research would explore the pros and cons of technology and intend to know a teacher interested in teaching language through technology.

description: We describe an approach to the study of neutrino masses that combines quantum optics techniques with radiation detectors to obtain unprecedented sensitivity. With it the search for Majorana neutrino masses down to $\sim$10 meV will become accessible. The experimental technique uses the possibility of individually detecting $\rm Ba^+$-ions in the final state of $\rm ^{136}Xe$ double-beta decay via resonant excitation with a set of lasers aimed at a specific location in a large Time Projection Chamber. The specificity of the atomic levels provides tagging and, together with more traditional event recognition parameters, greatly suppresses radioactive backgrounds.

description: We establish the future non-linear stability of Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) solutions to the Einstein-Euler equations of the universe filled with a large class of perfect fluids (the equations of state are allowed to be certain nonlinear or linear types both). Several previous results as specific examples can be covered in the results of this article. We emphasize that the future stability of FLRW metric for polytropic fluids with positive cosmological constant has been a difficult problem and can not be directly generalized from the previous known results. Our result in this article has not only covered this difficult case for the polytropic fluids, but also unified more types of fluids in a same scheme of proofs.

description: 1. Latar Belakang Menurut ISO 9241-11 (1998) , Usability adalah sejauh mana sebuah produk dapat digunakan oleh pengguna tertentu untuk mencapai tujuan tertentu dengan efektif, efisiensi dan pengguna menjadi puas dalam kontek penggunaan. [1] Dalam mengukur usability, perlu menggunakan pertanyaan-pertanyaan yang memiliki komponen-komponen tertentu untuk menggali pendapat responden. Komponen-komponen tersebut antara lain: 1. Learnability Learnability adalah tingkat kemudahan pengguna yang diukur dari pemakaian fungsi-fungsi dan fitur yang tersedia di sistem, web atau aplikasi. 2. Efficiency Efficiency menjelaskan kecepatan pengguna dalam mengerjakan perintah-perintah pada website atau aplikasi perangkat lunak tertentu. 3. Memorability Berkaitan dengan kemampuan pengguna mempertahankan pengetahuannya setelah jangka waktu tertentu. 4. Errors Menjelaskan jumlah error yang dilakukan oleh pengguna, tingkat kebosanan terhadap error dan cara memperbaiki error. 5. Satisfaction Komponen ini merupakan tingkat kepuasan pengguna setelah menggunakan website atau aplikasi.[2] Perkembangan teknologi dari zaman ke zaman berkembang sangat cepat dan semakin canggih. Internet adalah teknologi yang merupakan suatu media informasi yang tidak bisa lepas dari kehidupan saat ini. Salah satu indikatornya adalah bisa kita ketahui segala bentuk informasi, komunikasi dan interaksi sudah menggunakan internet. Mengingat pentingnya suatu informasi dalam suatu organisasi termasuk ukm (Unit Kegiatan Mahasiswa) kami mencoba merancang sebuah rancangan website ukm, yang dimaksudkan untuk mempermudah pengurus dan mahasiswa dalam berinteraksi, berbagi informasi dan berkomunikasi secara jarak jauh serta dengan harapan dapat mengurangi miskomunikasi. Dan rancangan website ini sendiri sangat cocok diterapkan dikampus ini, karena kampus ini berbasis IT hingga tidak asing lagi bagi mahasiswa yang akan lebih mempermudah dalam penggunaanya. Karena itulah kami memutuskan untuk merancang website UKM.
Spinning operators and defects in conformal field theory

description: We study the kinematics of correlation functions of local and extended operators in a conformal field theory. We present a new method for constructing the tensor structures associated to primary operators in an arbitrary bosonic representation of the Lorentz group. The recipe yields the explicit structures in embedding space, and can be applied to any correlator of local operators, with or without a defect. We then focus on the two-point function of traceless symmetric primaries in the presence of a conformal defect, and explain how to compute the conformal blocks. In particular, we illustrate various techniques to generate the bulk channel blocks either from a radial expansion or by acting with differential operators on simpler seed blocks. For the defect channel, we detail a method to compute the blocks in closed form, in terms of projectors into mixed symmetry representations of the orthogonal group.

Conductance fluctuations due to a single bistable scatterer in a weakly connected conductor.
Creators: name: Fal'ko, Vladimir I.
Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We study the effect of a single bistable scatterer on conductance of mesoscopic conductors in the crossover regime from open to closed systems. After the resistance of the contact between the metallic grain and bulk electrode exceeds the resistance of a grain, the effect of a bistability is enhanced and takes the universal form. Its efficiency scales with the cross-section of the bistable impurity and of conductances of contacts but is independent of this impurity position inside a sample. Mutual correlations between magneto-conductance fluctuations at two conductance levels also look universal. Enhancement of the conductance sensitivity to variations of impurity configurations in samples with highly resistive contacts transforms the spectral density of a quantum excess noise toward a white-noise behavior and requires higher stability of the sample in order to observe mesoscopic effects in direct-current measurements.

description: Bearing only cooperative localization has been used successfully on aerial and ground vehicles. In this paper we present an extension of the approach to the underwater domain. The focus is on adapting the technique to handle the challenging visibility conditions underwater. Furthermore, data from inertial, magnetic, and depth sensors are utilized to improve the robustness of the estimation. In addition to robotic applications, the presented technique can be used for cave mapping and for marine archeology surveying, both by human divers. Experimental results from different environments, including a fresh water, low visibility, lake in South Carolina; a cavern in Florida; and coral reefs in Barbados during the day and during the night, validate the robustness and the accuracy of the proposed approach.
