description: Numerical simulations of double-barred galaxies predict the build-up of different structural components (e.g., bulges, inner discs) in the central regions of disc galaxies. In those simulations, inner bars have a prominent role in the internal secular evolution of their host galaxies. The development of bulges and inner discs is, however, poorly understood observationally due to the small number of studies focusing on the stellar populations of these systems. In order to provide constraints on the relevant processes inducing the creation of these components in the presence of inner bars, we have carried out a detailed kinematical and stellar population analysis in a sample of four double-barred galaxies, ranging from SB0 to SBb, observed with integral-field spectroscopy. We find that the inner bars present distinct stellar population properties, being younger and more metal-rich than the surrounding bulges and outer bars. While we detect signatures of gas inflow through the inner bars, we find no evidence of associated star-forming regions or newly-formed structures around them. This result suggests that, regardless of their formation scenario, at present these inner bars are playing a moderate or even a minor role in the morphological evolution of this sample of double-barred galaxies.

Quantum criticality analysis by finite size scaling and exponential basis sets

description: We combine the finite size scaling method with the meshfree spectral method to calculate quantum critical parameters for a given Hamiltonian. The basic idea is to expand the exact wave function in a finite exponential basis set and extrapolate the information about system criticality from a finite basis to the infinite basis set limit. The used exponential basis set -though chosen intuitively- allows handling a very wide range of exponential decay rates and calculating multiple eigenvalues simultaneously. As a benchmark system to illustrate the combined approach, we choose the Hulthen potential. The results show that the method is very accurate and converges faster when compared with other basis functions. The approach is general and can be extended to examine near threshold phenomena for atomic and molecular systems based on even-tempered exponential and Gaussian basis functions.

State tomography via weak measurements

description: Recent work has revealed that the wave function of a pure state can be measured directly and that complementary knowledge of a quantum system can be obtained simultaneously by weak measurements. However, the original scheme applies only to pure states, and it is not efficient because most of the data are discarded by post-selection. Here, we propose tomography schemes for pure states and for mixed states via weak measurements, and our schemes are more efficient because we do not discard any data. Furthermore, we demonstrate that any matrix element of a general state can be directly read from an appropriate weak measurement. The density matrix (with all of its elements) represents all that is directly accessible from a general measurement.

description: In the present paper, we prove the a priori estimates of Sobolev norms for a free boundary problem of the incompressible inviscid MHD equations in all physical spatial dimensions $n=2$ and 3 by adopting a geometrical point of view used in Christodoulou-Lindblad CPAM 2000, and estimating quantities such as the second fundamental form and the velocity of the free surface. We identify the well-posedness condition that the outer normal derivative of the total pressure including the fluid and magnetic pressures is negative on the free boundary, which is similar to the physical condition (Taylor sign condition) for the incompressible Euler equations of fluids.

An Integrated Data-Driven Two-Stage Stochastic Capacitated Lot-Sizing Problem in a Two-Plants Industrial Symbiosis Supply Chain

Publisher: name: Zenodo
Year: 2022

description: We studied a supply chain in which two production plants collaborating in an industrial symbiosis to satisfy their stochastic demands cost-effectively. The research work is motivated by the circular economy, an emerging concept that eases extending products’ life cycle through reusing, refurbishing, sharing, and recycling. One of the main obstacles in implementing industrial symbiosis is the lack of cooperation and trust between the stakeholders. Therefore, it seems necessary for decision-makers to provide a framework for optimizing the tactical plan to realize a strategic advantage from engaging in a symbiosis while considering uncertain market demand to provide a compatible production plan with the real-world working environment. Different approaches such as stochastic and robust optimization will be evaluated in terms of solution quality and computational time.

description: Pygmy and Giant Dipole Resonance (PDR and GDR) in Ni isotopes have been investigated by Coulomb excitation in the framework of the Isospin-dependent Quantum Molecular Dynamics model (IQMD). The spectra of $γ$ rays are calculated and the peak energy, the strength and Full Width at Half Maximum (FWHM) of GDR and PDR have been extracted. Their sensitivities to nuclear equation of state, especially to its symmetry energy term are also explored. By a comparison with the other mean-field calculations, we obtain the reasonable values for symmetry energy and its slope parameter at saturation, which gives an important constrain for IQMD model. In addition, we also studied the neutron excess dependence of GDR and PDR parameters for Ni isotopes and found that the energy-weighted sum rule (EWSR) $PDR_{m_1}/GDR_{m_1}%$ increases linearly with the neutron excess.

Recently, as extensions of Jacobson's lemma, Corach, Duggal and Harte studied common properties of $AC-I$ and $BA-I$ in algebraic viewpoint and also obtained some topological analogues. In this note, we continue to investigate common properties of $AC$ and $BA$ from the viewpoint of spectral theory. In particular, we give an affirmative answer to one question posed by Corach et al. by proving that $AC - I$ has closed range if and only if $BA - I$ has closed range.

Multi-Objective Optimization: Which Solution Do You Prefer?
Creators: name: Heidari, Arash

Publisher: name: Zenodo
Year: 2022

description: Real-world problems usually consist of two or more conflicting objectives; hence there is no single solution that optimizes all of the objectives simultaneously. At the end of the optimization process, there is a set of solutions, each of which is better in one objective and worse at least in another one. In other words, they do not dominate each other. The final non-dominated solutions are called the Pareto front in the objective space. Multi-objective optimization requires many evaluations to identify a sufficiently dense approximation of the Pareto front. Especially for a higher number of objectives, extracting the Pareto front is neither easy nor cheap. At the same time, not all the solutions in the Pareto front are attractive to the Decision-Maker, and they might prefer a solution where there is a desirable trade-off between different objectives. An example of such an attractive solution is the knee point of the Pareto front, although there is no unique definition of the knee point in the literature. Additionally, all the current research on finding the knee point is based on evolutionary algorithms, which evaluate the objective functions many times; hence they are not data-efficient. Although they are still preferred when the objective functions exhibit a high non-linear behaviour or the cost of each evaluation is neither time-consuming nor expensive. In this work, we propose to detect knee points in a data-efficient manner (i.e., with a limited number of time-consuming evaluations) based on two different definitions of where a knee point is. Particularly, we propose several novel acquisition functions in the Bayesian Optimization framework for detecting these knees, which allows for scaling to many objectives. The suggested acquisition functions are evaluated on various benchmarks with promising results.

description: At Kamioka Observatory many activities for low energy rare event search are ongoing. Super-Kamiokande(SK), the largest water Cherenkov neutrino detector, currently continues data taking as the fourth phase of the experiment (SK-IV). In SK-IV, we have upgraded the water purification system and tuned water flow in the SK tank. Consequently the background level was lowered significantly. This allowed SK-IV to derive solar neutrino results down to 3.5MeV energy region. With these data, neutrino oscillation parameters are updated from global fit; $Δm^2_{12}=7.44^{+0.2}_{-0.19}\times10^{-5} {\rm eV}^2$, $\sin^2θ_{12}=0.304\pm0.013$, $\sin^2θ_{13}=0.030^{+0.017}_{-0.015}$. NEWAGE, the directional sensitive dark matter search experiment, is currently operated as "NEWAGE-0.3a" which is a $0.20\times0.25\times0.31$ m$^3$ micro-TPC filled with CF4 gas at 152 Torr. Recently we have developed "NEWAGE-0.3b". It was succeeded to lower the operation pressure down to 76 Torr and the threshold down to 50 keV (F recoils). XMASS experiment is looking for scintillation signals from dark matter interaction in 1 ton of liquid xenon. It was designed utilizing its self-shielding capability with fiducial volume confinement. However, we could lower the analysis threshold down to 0.3 keVee using whole volume of the detector. In February 2012, low threshold and very large exposure data (5591 kg$\cdot$days) were collected. With these data, we have excluded some part of the parameter spaces claimed by DAMA/LIBRA and CoGeNT experiments.

A new substantive proton to electron mass ratio constraint on rolling scalar field cosmologies

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: New PKS1830-211 radio frequency observations of methanol at a redshift of 0.88582 have established the most stringent limits on changes in the proton to electron mass ratio mu to date. The observations place the limit of (delta mu)/mu = (0.0 +/- 1.0) x 10^{-7} which is approximately a factor of four lower than the previous lowest limit at a redshift of 0.6742. This stringent limit at a look back time of roughly half the age of the universe has profound implications for rolling scalar field cosmologies and the new physics that they require. Many of these cosmologies invoke a scalar field phi that is also coupled to the electromagnetic field causing the values of the fundamental constants, mu and the fine structure constant alpha to roll with time. If the lowest expected value of the coupling to mu, zeta_{mu}$ is invoked the new limit requires a limit on the dark energy equation of state parameter w such that w+1 = 0.001 at a redshift of 0.88582. This eliminates almost all of the expected parameter space for such cosmologies and new physics that have a coupling to the electromagnetic field. In these cases the limit requires that w must be extremely close to -1 for the last half of the age of the universe or that the coupling of the rolling scalar field to mu and the electromagnetic field be significantly below or at the limit of its expected range. The new observations solidify the role of fundamental constants in providing probes of the possible cosmologies and new physics to explain the acceleration of the expansion of the universe.

description: Reinforcement of the puzzle about the proton charge radius r, stimulated by the recent experiments with muonic hydrogen induced news discussions on the subject, and now some physicists are ready to adopt the exotic properties of muon, lying beyond the Standard Model, in order to explain the difference between the results of muonic hydrogen experiments (r=0.84087(39) fm) and CODATA-2010 value r=0.8775(51) fm based on electron-proton scattering and H spectroscopy. In the present contribution we suggest a way to achieve a progress in the entire problem via paying attention on a logical inconsistency of fundamental equations of atomic physics, constructed by analogy with corresponding classical equations without, however, taking into account a purely bound nature of electromagnetic field generated by electrically bound particles in the stationary energy states. We suggest eliminating this inconsistency via introducing some appropriate correcting factors into these equations, which involve the requirement of total momentum conservation in the system of bound particles in the absence of electromagnetic radiation. We further show that this approach allows not only eliminating long-standing discrepancies between theory and experiment in physics of simple atoms, but also yields the same estimation for the proton size in the classic 2S-2P Lamb shift in hydrogen, 1S Lamb shift in hydrogen, and 2S-2P Lamb shift in muonic hydrogen, with the mean value r=0.841 fm. Finally, we suggest the crucial experiment for verification of the validity of pure bound field corrections: the measurement of lifetime of bound moun in meso-atoms with large Z, where the standard calculations and our predictions essentially deviate from each other, and some of the available experimental results (Yovanovitch, Phys. Rev. 117 (1960) 1580) strongly support our approach.

description: A recently proposed device, dubbed half-Josephson laser, provides a phase-lock between the optical phase and the superconducting phase difference between the leads of the device. In this paper we propose to utilize this phase-lock for stabilization of voltage fluctuations, by two optical feedback schemes. The first scheme involves a single half-Josephson laser and allows to significantly decrease the diffusion coefficient of the superconducting phase difference. The second scheme involves a stable optical source and a fluctuating half-Josephson laser and permits quenching of the diffusion of the relative phase of the lasers. This opens up perspectives of the optical control of the superconducting phase and voltage fluctuations.

description: This research addresses the critical topic of sense of belonging in higher education, focusing specifically on the course level and within the online learning context. Utilizing a quantitative approach, our study aimed to create and assess the Brief Course Belonging Scale (BCBS) for its applicability across diverse postsecondary learning environments. Conducted at a prominent US southeastern university, a psychometric investigation was undertaken. The findings affirm the unidimensional nature of BCBS data across delivery contexts, establishing convergent validity by demonstrating positive associations between BCBS scores, university-level belonging, connectedness, and academic motivation. Discriminant validity was established through minimal associations with loneliness. While detecting differential item functioning in one item, this did not compromise the validity and reliability of scores. The study concludes with psychometric implications regarding the domain-specificity of the course delivery context and recommends the administration of the BCBS to a broader, more diverse student population.

description: We examine how metallicity affects convection and overshoot in the superadiabatic layer of main sequence stars. We present results from a grid of 3D radiation hydrodynamic simulations with four metallicities ($Z=0.040$, 0.020, 0.010, 0.001), and spanning a range in effective temperature ($4950 < \rm T_{\rm eff} < 6230$). We show that changing the metallicity alters properties of the convective gas dynamics, and the structure of the superadiabatic layer and atmosphere. Our grid of simulations show that the amount of superadiabaticity, which tracks the transition from efficient to inefficient convection, \rev{is sensitive to changes in metallicity. We find that increasing the metallicity forces the location of the transition region to lower densities and pressures, and results in larger mean and turbulent velocities throughout the superadiabatic region.} We also quantify the degree of convective overshoot in the atmosphere, and show that it increases with metallicity as well.

description: Belgian Offshore Wind Farms are located in area where tidal current speed is significant. Therefore, it is important to understand the interaction between waves, current, and the structure to assess wave field behaviour around the monopile. In order to properly assess the wave field around the monopile, preliminary study is conducted by investigating the wave and current interaction. Generation and absorption of wave-current condition are performed with modified OpenFOAM Waves2Foam library where the current velocity is superimposed on wave velocity. In the simulation region it is noticed that wave-current interaction is occuring. The wave length is found to get shorter in the similar value of theoretical estimation in the opposing current cases. However, the wave height increment is found to be lower than the theoretical estimation. Thus the wave height modification in velocity superposition requires further research investigation

description: Using non-perturbative lattice method we studied hadronic screening correlators above and immediately below the deconfinement transition temperature, Tc, in the quenched approximation with lattice spacing of 1/(8T) using clover improved Wilson fermions. Simulations were performed at temperatures T /Tc = 0, 0.95 and 1.5. Mesonic screening correlators show no statistically significant thermal effects below Tc, and clear evidence for weakly interacting quarks above Tc . Baryon screening correlators yield similar physics above Tc, but show precursor effects for chiral symmetry restoration below Tc .

description: We extend a recent study of susceptible-infected-removed epidemic processes with long range infection (referred to as I in the following) from 1-dimensional lattices to lattices in two dimensions. As in I we use hashing to simulate very large lattices for which finite size effects can be neglected, in spite of the assumed power law $p({\bf x})\sim |{\bf x}|^{-σ-2}$ for the probability that a site can infect another site a distance vector ${\bf x}$ apart. As in I we present detailed results for the critical case, for the supercritical case with $σ= 2$, and for the supercritical case with $0< σ< 2$. For the latter we verify the stretched exponential growth of the infected cluster with time predicted by M. Biskup. For $σ=2$ we find generic power laws with $σ-$dependent exponents in the supercritical phase, but no Kosterlitz-Thouless (KT) like critical point as in 1-d. Instead of diverging exponentially with the distance from the critical point, the correlation length increases with an inverse power, as in an ordinary critical point. Finally we study the dependence of the critical exponents on $σ$ in the regime $0

description: After hundred or thousand years of weathering, those distinctive building façade are very vulnerable to the changing environment and requires regular maintenance and preservation to keep it long lasting. However, In recent years, the investment in heritage conservation and renovation demonstrates an increasing tendency both financially and materially due to the climate change issues and the large amount of historic buildings. To better preserve those buildings is to understand how
 it deteriorated. Because of that we have to understand the characteristics of building materials and how they response to the environment. How the heat, air and moisture migrate in the building envelop and cause the deterioration in the façade? How different climate scenarios will impact the deterioration in building façade and how the climate change and future climate projection may influent the deterioration? . To make this projection convincing we have to do a large amount simulation to simulate various conditions until finally we build a large database and make a decision tree in a scientific and statistic way.

description: The two-loop QCD corrections to vector boson pair production at hadron colliders involve a new class of Feynman integrals: two-loop four-point functions with two off-shell external legs. We describe their reduction to a small set of master integrals by solving linear relations among them. We then use differential equations in the external invariants to compute all master integrals that are relevant to planar Feynman amplitudes. Our results are expressed analytically in terms of generalised harmonic polylogarithms. The calculation relies heavily on techniques that exploit the algebraic structure of these functions, which we describe in detail.

High-Speed Coherent Receivers for Data Center Links
Creators: name: Declercq, Jakob

Publisher: name: Zenodo
Year: 2022

description: In recent years, the continuous growth of Internet traffic is boosting the demand of short-reach optical links in data centers, vastly driven by new applications such as Cloud Computing, Virtual Reality/Augmented Reality, and Internet of Things. According to a recent report from Cisco, most of the datacenter traffic stays within the mega datacenters, further increasing the demand of faster optical interconnections. To date, intensity-modulation/direct-detection (IMDD) solutions still dominate the market of short-reach optical interconnects, however experiencing lofty challenges in scaling up beyond 100Gbps per wavelength (i.e. 50GBaud PAM-4 modulation). Coherent detection offers high spectral efficiency and receiver sensitivity, but conventional DSP-based coherent receivers have prohibitively high cost and power consumption for intra-data-center links.
 This PhD research focuses on increasing the speed of these links. We have designed a transimpedance amplifier that aims at a symbol rate of 100GBaud. In the first instance, I will use this chip in an IMDD receiver configuration. After that, balanced photodiodes will be used to extend the receiver to coherent formats. In addition, "DSP-lite coherent detection" techniques using analog/mixed-signal processing with an optoelectronic phase-locked loop promise to drastically lower power consumption and complexity compared to DSP-based solutions.

Non-equilibrium dynamics of photo-excited electrons in graphene: collinear scattering, Auger processes, and the impact of screening

description: We present a combined analytical and numerical study of the early stages (sub-100fs) of the non-equilibrium dynamics of photo-excited electrons in graphene. We employ the semiclassical Boltzmann equation with a collision integral that includes contributions from electron-electron (e-e) and electron-optical phonon interactions. Taking advantage of circular symmetry and employing the massless Dirac Fermion (MDF) Hamiltonian, we are able to perform an essentially analytical study of the e-e contribution to the collision integral. This allows us to take particular care of subtle collinear scattering processes - processes in which incoming and outgoing momenta of the scattering particles lie on the same line - including carrier multiplication (CM) and Auger recombination (AR). These processes have a vanishing phase space for two dimensional MDF bare bands. However, we argue that electron-lifetime effects, seen in experiments based on angle-resolved photoemission spectroscopy, provide a natural pathway to regularize this pathology, yielding a finite contribution due to CM and AR to the Coulomb collision integral. Finally, we discuss in detail the role of physics beyond the Fermi golden rule by including screening in the matrix element of the Coulomb interaction at the level of the Random Phase Approximation (RPA), focusing in particular on the consequences of various approximations including static RPA screening, which maximizes the impact of CM and AR processes, and dynamical RPA screening, which completely suppresses them.
