La relazione tra saggio di profitto e tasso d’interesse e il ruolo della profittabilità bancaria
Creators: name: Zolea, Riccardo
Publisher: name: Moneta e Credito
Year: 2021

description: The paper focuses on theoretical aspects of the relationship between the profit rate and the interest rate. Two roughly opposite approaches emerge in the literature: in a first one, the interest rate determines the profit rate, and therefore income distribution; in a second one, the profit rate regulates the interest rate, once distribution is already determined. The introduction of the condition that bank capital receives a profit rate at least equal to the general one makes it possible to conceptualize the interest rate as the endogenously determined price of the commodity ‘loan’, and the central bank rate as the price of a ‘bank input’.

Jet measurements by the CMS experiment in pp and PbPb collisions

Subjects: subject: Nuclear Experiment (nucl-ex)

description: The energy loss of fast partons traversing the strongly interacting matter produced in high-energy nuclear collisions is one of the most interesting observables to probe the nature of the produced medium. The multipurpose Compact Muon Solenoid (CMS) detector is well designed to measure these hard scattering processes with its high resolution calorimeters and high precision silicon tracker. Analyzing data from pp and PbPb collisions at a center-of-mass energy of 2.76 TeV parton energy loss is observed as a significant imbalance of dijet transverse momentum. To gain further understanding of the parton energy loss mechanism the redistribution of the quenched jet energy was studied using the transverse momentum balance of charged tracks projected onto the direction of the leading jet. In contrast to pp collisions, a large fraction the momentum balance for asymmetric jets is found to be carried by low momentum particles at large angular distance to the jet axis. Further, the fragmentation functions for leading and subleading jets were reconstructed and were found to be unmodified compared to measurements in pp collisions. The results yield a detailed picture of parton propagation in the hot QCD medium.

Os algoritmos de Levemberg-Marquardt, Regularização Bayesiana e Gradiente Conjugado Escalado tiveram seus resultados avaliados pelo Coeficiente de Correlação (R) e Mean Squared Error (MSE), quanto mais próximo de 1 o R e menor o MSE, melhores os resultados. O conjunto de 1.200 amostras medidas em campo foi dividido aleatoriamente em 80% para o treinamento, 10% para validação e 10% para os testes. Os três modelos ofereceram elevada precisão, sendo que o algoritmo de Regularização Bayesiana apresentou os melhores indicadores estatísticos, tanto no seu maior valor de regressão R quanto no menor MSE, em comparação com os algoritmos de Levemberg-Marquardt e Gradiente Conjugado Escalado, respectivamente.
description: This study presents a comparative analysis of Artificial Neural Networks based on predictive algorithms to estimate the electric field strength in digital terrestrial television signals. The Levemberg-Marquardt, Bayesian Regularization and Scaled Conjugate Gradient algorithms had their results evaluated by the Correlation Coefficient (R) and Mean Squared Error (MSE), the closer to 1 the R and the lower the MSE, better the results. The set of 1.200 samples measured in the field was randomly divided into 80% for training, 10% for validation and 10% for testing. The three models provided high precision, and the Bayesian Regularization algorithm presented the best statistical indicators, both in its highest R regression value and in the lowest MSE, compared to the algorithms of Levemberg-Marquardt e Scaled Conjugate Gradient, respectively.

description: We study the normal state of a 3-$d$ homogeneous dipolar Fermi gas beyond the Hartree-Fock approximation. The correlation energy is found of the same order as the Fock energy, unusually strong for a Fermi-liquid system. As a result, the critical density of mechanical collapse is smaller than that estimated in the Hartree-Fock approximation. With the correlation energy included, a new energy functional is proposed for the trapped system, and its property is explored.

description: We show that the relation between the Schrödinger equation and diffusion processes has an algebraic nature and can be revealed via the structure of "duplex numbers." This helps one to clarify that quantum mechanics cannot be reduced to diffusion theory. Also, a generalized version of quantum mechanics where $\C$ is replaced by a normed algebra with a unit is proposed.

description: The optical properties of single InAsP/InP quantum dots are investigated by spectrally-resolved and time-resolved photoluminescence measurements as a function of excitation power. In the short-wavelength region (below 1.45 $μ$m), the spectra display sharp distinct peaks resulting from the discrete electron-hole states in the dots, while in the long-wavelength range (above 1.45 $μ$m), these sharp peaks lie on a broad spectral background. In both regions, cascade emission observed by time-resolved photoluminescence confirms that the quantum dots possess discrete exciton and multi-exciton states. Single photon emission is reported for the dots emitting at 1.3 $μ$m through anti-bunching measurements.

description: We report the detection of three new exoplanets from Keck Observatory. HD 163607 is a metal-rich G5IV star with two planets. The inner planet has an observed orbital period of 75.29 $\pm$ 0.02 days, a semi-amplitude of 51.1 $\pm$ 1.4 \ms, an eccentricity of 0.73 $\pm$ 0.02 and a derived minimum mass of \msini = 0.77 $\pm$ 0.02 \mjup. This is the largest eccentricity of any known planet in a multi-planet system. The argument of periastron passage is 78.7 $\pm$ 2.0$^{\circ}$; consequently, the planet's closest approach to its parent star is very near the line of sight, leading to a relatively high transit probability of 8%. The outer planet has an orbital period of 3.60 $\pm$ 0.02 years, an orbital eccentricity of 0.12 $\pm$ 0.06 and a semi-amplitude of 40.4 $\pm$ 1.3 \ms. The minimum mass is \msini = 2.29 $\pm$ 0.16 \mjup. HD 164509 is a metal-rich G5V star with a planet in an orbital period of 282.4 $\pm$ 3.8 days and an eccentricity of 0.26 $\pm$ 0.14. The semi-amplitude of 14.2 $\pm$ 2.7 \ms\ implies a minimum mass of 0.48 $\pm$ 0.09 \mjup. The radial velocities of HD 164509 also exhibit a residual linear trend of -5.1 $\pm$ 0.7 \ms\ per year, indicating the presence of an additional longer period companion in the system. Photometric observations demonstrate that HD 163607 and HD 164509 are constant in brightness to sub-millimag levels on their radial velocity periods. This provides strong support for planetary reflex motion as the cause of the radial velocity variations.

These issues include the gauge-fixed path integral representation of this determinant, the monodromy method of its calculation and the combination of the heat kernel and zeta-function technique for the derivation of its period dependence. Motivations for this particular problem, coming from applications in quantum cosmology, are also briefly discussed. They include the problem of microcanonical initial conditions in cosmology driven by a conformal field theory, cosmological constant and cosmic microwave background problems.

description: We recently reported on the radio-frequency attenuation length of cold polar ice at Summit Station, Greenland, based on bistatic radar measurements of radio-frequency bedrock echo strengths taken during the summer of 2021. Those data also include echoes attributed to stratified impurities or dielectric discontinuities within the ice sheet (layers), which allow studies of a) estimation of the relative contribution of coherent (discrete layers, e.g.) vs. incoherent (bulk volumetric, e.g.) scattering, b) the magnitude of internal layer reflection coefficients, c) limits on the azimuthal asymmetry of reflections (birefringence), and d) limits on signal dispersion in-ice over a bandwidth of ~100 MHz. We find that i) after averaging 10000 echo triggers, reflected signal observable over the thermal floor (to depths of approximately 1500 m) are consistent with being entirely coherent, ii) internal layer reflection coefficients are measured at approximately -60 to -70 dB, iii) birefringent effects for vertically propagating signals are smaller by an order of magnitude relative to comparable studies performed at South Pole, and iv) within our experimental limits, glacial ice is non-dispersive over the frequency band relevant for neutrino detection experiments.
Single photon absorption and dynamic control of a coupled quantum dot-cavity system

Year: 2011
Subjects: subject: Quantum Physics (quant-ph)

description: We theoretically investigate the dynamic interaction of a quantum dot in a nanocavity with timesymmetric single photon pulses. The simulations, based on a wavefunction approach, reveal that almost perfect single photon absorption occurs for quantum dot-cavity systems operating on the edge between strong and weak coupling regime. The computed maximum absorptions probability is close to unity for pulses with a typical length comparable to the half of the Rabi period. Furthermore, the dynamic control of the quantum dot energy via electric fields allows the freezing of the light-matter interaction leaving the quantum dot in its excited state. Shaping of single photon wavepackets by the electric field control is limited by the occurrence of chirping of the single photon pulse. This understanding of the interaction of single photon pulses with the quantum dot-cavity system provides the basis for the development of advanced protocols for quantum information processing in the solid state.

Radio Supernovae in the Great Survey Era

description: Radio properties of supernova outbursts remain poorly understood despite longstanding campaigns following events discovered at other wavelengths. After ~ 30 years of observations, only ~ 50 supernovae have been detected at radio wavelengths, none of which are Type Ia. Even the most radio-loud events are ~ 10^4 fainter in the radio than in the optical; to date, such intrinsically dim objects have only been visible in the very local universe. The detection and study of radio supernovae (RSNe) will be fundamentally altered and dramatically improved as the next generation of radio telescopes comes online, including EVLA, ASKAP, and MeerKAT, and culminating in the Square Kilometer Array (SKA); the latter should be > 50 times more sensitive than present facilities. SKA can repeatedly scan large (> 1 deg^2) areas of the sky, and thus will discover RSNe and other transient sources in a new, automatic, untargeted, and unbiased way. We estimate SKA will be able to detect core-collapse RSNe out to redshift z ~ 5, with an all-redshift rate ~ 620 events yr^-1 deg^-2, assuming a survey sensitivity of 50 nJy and radio lightcurves like those of SN 1993J. Hence SKA should provide a complete core-collapse RSN sample that is sufficient for statistical studies of radio properties of core-collapse supernovae. EVLA should find ~ 160 events yr^-1 deg^-2 out to redshift z ~ 3, and other SKA precursors should have similar detection rates. We also provided recommendations of the survey strategy to maximize the RSN detections of SKA. This new radio core-collapse supernovae sample will complement the detections from the optical searches, such as the LSST, and together provide crucial information on massive star evolution, supernova physics, and the circumstellar medium, out to high redshift. Additionally, SKA may yield the first radio Type Ia detection via follow-up of nearby events discovered at other wavelengths.

description: Probability distributions which emerge from the formalism of nonextensive statistical mechanics have been applied to a variety of problems. In this paper we unite modeling of such distributions with the model of widespread 1/f noise. We propose a class of nonlinear stochastic differential equations giving both the q-exponential or q-Gaussian distributions of signal intensity, revealing long-range correlations and 1/f^beta behavior of the power spectral density. The superstatistical framework to get 1/f^beta noise with q-exponential and q-Gaussian distributions of the signal intensity in is proposed, as well.
Towards RNA delivery via bacterial secretion systems
Creators: name: Walker, Barnabas James
Publisher: name: Imperial College London
Year: 2020

description: RNA is a versatile macromolecule with numerous therapeutic applications. However, delivering RNA and RNA:protein complexes efficiently into the appropriate cells and cellular compartments remains a significant challenge. As our ability to engineer bacteria has become more sophisticated, there has been increasing interest in utilising bacteria as intelligent therapeutic agents in order to capitalise on many advantageous characteristics acquired over the course of millions of years of evolution. In particular, several bacterial secretion systems have evolved the ability to deliver complex macromolecules such as proteins and DNA across cell membranes and into target cells. In this thesis, we explore ways of expanding these delivery capabilities further by investigating ways in which bacterial secretion systems could be harnessed for delivery of RNA and RNA:protein complexes. The type IV secretion system is able to deliver DNA into bacterial and eukaryotic cells via a covalent linkage to a secreted protein. In an attempt to mimic this process, we explore the use of a previously characterised synthetic ribozyme to ligate RNA to secreted proteins. Whilst we were able to confirm functioning of the ribozyme in vitro, no evidence could be found for ligation occurring in vivo. In a second approach, we work with the type VI secretion system (T6SS) which is unique in its ability to deliver proteins in a folded state and may therefore be able to deliver ribonucleoprotein complexes such as Cas9 with a guide RNA. A new assay for studying the translocation of heterologous proteins into bacteria via the T6SS is developed and used to test several T6SS substrates for their ability to support the delivery of Cre recombinase. None are able to do so, however a new cloning strategy is developed to facilitate higher throughput testing of candidate carrier proteins. Delivery of heterologous proteins into human cells is also explored via a previously published assay. We find that the readout of the assay is obscured by the intrinsic fluorescence of the bacteria used and make recommendations for a new assay.

description: The limitation of the crack width is of central importance for the design in the serviceability limit state. For FRP‐reinforced concrete members, the crack width has to be limited for service condition in use and not due to corrosion protection. In this paper, an experimental program of pull‐out tests and slender concrete cylinders with basalt fiber‐reinforced polymer rebars under centric tension load is presented. The used basalt fiber‐reinforced polymer rebars are sand coated and have in addition a helically wrapped thread for a decent profiling. Equations to calculate crack spacing and crack width of FRP‐reinforced concrete is derived and calibrated with the obtained experimental results. Finally, the equations are verified with experimental data from other authors and a crack model is given for reinforced concrete members with FRP rebars with a helically wrapped and sand coated surface.
Gap probabilities in random matrix theory
Creators: name: Maroudas, Theo-Harris
Publisher: name: Imperial College London
Year: 2020

description: The main achievement of this work is in providing a proof of the value of the multiplicative constant arising from the Airy-kernel determinant on two large gaps. In fact, we prove a full asymptotic formula up to decaying terms. The constant in this expression, in particular, determines the pre-factor of the determinant. The kernel of Airy functions is universal in random matrix theory as it arises at the soft edge of many ensembles of random matrices, most notably the Gaussian Unitary Ensemble. The proof adds to a series of results since Dyson and, Tracy and Widom, in studying this type of Fredholm determinants. Our method of proof relies on the steepest descent approach to Riemann-Hilbert problems, introduced by Deift and Zhou. By extending their approach to our particular setting we, in addition, contribute to the development of an important method.

description: In Thailand's capital, transportation problems such as traffic congestion and air pollution rank among the worst in the world. These problems are best viewed from an historical and contemporary perspective.rather than from narrowly-defined technical point of view. The direct impacts of these problems are most felt in the Bangkok Metropolitan Region and its extended periphery, which together comprise the Extended Bangkok Metropolitan Region. fu the past, conventional transportation planning in Bangkok has focused on increasing supply of infrastructure in an attempt to meet travel demand. In spite of plans for mass rapid transit systems, the focus has been on large scale road projects such as elevated expressways. However, most transportation planners and policy makers in Bangkok now recognize that the only hope for short to medium term amelioration of Bangkok's transportation problems lies with managing demand for transportation infrastructure. Thus, a number of Transportation Demand Management measures have been proposed and studied for implementation in Bangkok. Based on analysis of some political and cultural factors in Bangkok, this research suggests that these measures are unlikely to be successfully implemented. Both the old conventional wisdom (increasing supply of transportation infrastructure in an attempt to meet demand) and the new conventional wisdom (managing demand) of transportation planning are either inapplicable or ineffective measures to address transportation problems in the Bangkok urban region. The conclusion to this research recommends some broad, general measures that could be taken to address transportation problems in Bangkok.

description: According to the driving potential of a fissile system, we propose a phenomenological fission potential for a description of the pre-neutron emission mass distributions of neutron-induced actinide fission. Based on the nucleus-nucleus potential with the Skyrme energy-density functional, the driving potential of the fissile system is studied considering the deformations of nuclei. The energy dependence of the potential parameters is investigated based on the experimental data for the heights of the peak and valley of the mass distributions. The pre-neutron emission mass distributions for reactions 238U(n, f), 237Np(n, f), 235U(n, f), 232Th(n, f) and 239Pu(n, f) can be reasonably well reproduced. Some predictions for these reactions at unmeasured incident energies are also presented.

description: Von Neumann's statistical theory of quantum measurement interprets the instantaneous quantum state and derives instantaneous classical variables. In realty, quantum states and classical variables coexist and can influence each other in a time-continuous way. This has been motivating investigations since longtime in quite different fields from quantum cosmology to optics as well as in foundations. Different theories (mean-field, Bohm, decoherence, dynamical collapse, continuous measurement, hybrid dynamics, e.t.c.) emerged for what I call `coexistence of classical continuum with quantum'. I apply to these theories a sort of `free will' test to distinguish `tangible' classical variables useful for causal control from useless ones.

description: Data on inclusive dielectron production are presented for the reaction p+p at 2.2 GeV measured with the High Acceptance DiElectron Spectrometer (HADES). Our results supplement data obtained earlier in this bombarding energy regime by DLS and HADES. The comparison with the 2.09 GeV DLS data is discussed. The reconstructed e+e- distributions are confronted with simulated pair cocktails, revealing an excess yield at invariant masses around 0.5 GeV/c2. Inclusive cross sections of neutral pion and eta production are obtained.

description: We describe how we integrated discovery-based teaching modules in an enrichment program for high school students with the aim of enhancing their knowledge and skills to empower them to take charge of their own health risks and well-being. We developed several educational modules for high school students that provided them with an opportunity to learn and explore the foundations of physiological systems, nutrient needs to maintain health, and the impact that environmental factors can have on them. The modules included videos, discussion boards, games, readings, and labs. A total of 43 high school students participated in the program. Overall, the quality of the educational content in the modules was rated highly by the students and they indicated that the educational experience inspired them to learn more about the physiology and nutrition concepts associated with human metabolism, and the importance of healthy food choices to maintain health.
A detailed description of newly-discovered remains of Maiasaura peeblesorum (Reptila: ornithischia) and a revised diagnosis of the genus

description: A newly-discovered hadrosaur from the Two Medicine Formation, Teton County, Montana, is described in detail. The description of the skull is the most complete of any produced for a hadrosaur, and the postcranial skeleton provides the first information on an almost complete adult Maiasaura. Information resulting from this detailed examination is used as a base for comparisons with other specimens and reports in the literature. Although the new specimen differs in detail from the holotype, it (OTM F138) was determined to be Maiasaura peeblesorum. This classification led to a revision of the diagnosis of Maiasaura. Several previously unrecognized, taxonomically important characters were identified. The comparisons revealed discrepancies concerning both terminology and interpretation of certain features of the hadrosaur skeleton. These are discussed. In addition, a formula applicable to most hadrosaur specimens was derived for estimating total animal length from the length of the femur.

description: In the present paper, we provide an addendum to improve the efficiency of generating unweighted events within PYTHIA environment for the generator BCVEGPY2.1 [C.H. Chang, J.X. Wang and X.G. Wu, Comput.Phys.Commun.{\bf 174}, 241(2006)]. This trick is helpful for experimental simulation. Moreover, the BCVEGPY output has also been improved, i.e. one Les Houches Event common block has been added so as to generate a standard Les Houches Event file that contains the information of the generated $B_c$ meson and the accompanying partons, which can be more conveniently used for further simulation.

Creators: name: Bremm, Sophia

Publisher: name: Wiley‐VCH
Year: 2023

description: For numerous problems in structural mechanics, a repeated solution of partial differential equations (PDEs), varying certain input parameters, is necessary. Solving the PDE for a large number of different input parameter sets using a full‐dimensional finite element method, requires repeated solving of large systems of equations and, thus, leads to a high computational effort. The aim of model order reduction techniques is to reduce the computational complexity in such calculations. In order to achieve this, the idea of the reduced basis method [1–3] is to replace the high‐dimensional model with a lower dimensional model, which is realized by forming a basis of solutions of the full problem for selected parameter sets. Key to determining suitable parameter sets is an appropriate error estimator.

description: We present R-Band light curves of Type II supernovae (SNe) from the Caltech Core Collapse Project (CCCP). With the exception of interacting (Type IIn) SNe and rare events with long rise times, we find that most light curve shapes belong to one of three distinct classes: plateau, slowly declining and rapidly declining events. The last class is composed solely of Type IIb SNe which present similar light curve shapes to those of SNe Ib, suggesting, perhaps, similar progenitor channels. We do not find any intermediate light curves, implying that these subclasses are unlikely to reflect variance of continuous parameters, but rather might result from physically distinct progenitor systems, strengthening the suggestion of a binary origin for at least some stripped SNe. We find a large plateau luminosity range for SNe IIP, while the plateau lengths seem rather uniform at approximately 100 days. As analysis of additional CCCP data goes on and larger samples are collected, demographic studies of core collapse SNe will likely continue to provide new constraints on progenitor scenarios.

description: Worldwide Interoperability for Microwave Access (WiMAX) networks were expected to be the main Broadband Wireless Access (BWA) technology that provided several services such as data, voice, and video services including different classes of Quality of Services (QoS), which in turn were defined by IEEE 802.16 standard. Scheduling in WiMAX became one of the most challenging issues, since it was responsible for distributing available resources of the network among all users; this leaded to the demand of constructing and designing high efficient scheduling algorithms in order to improve the network utilization, to increase the network throughput, and to minimize the end-to-end delay. In this study, we presenedt a simulation study to measure the performance of several scheduling algorithms in WiMAX, which were Strict Priority algorithm, Round-Robin (RR), Weighted Round Robin (WRR), Weighted Fair Queuing (WFQ), Self-Clocked Fair (SCF), and Diff-Serv Algorithm.

description: It is well known that $li(x)>π(x)$ (i) up to the (very large) Skewes' number $x_1 \sim 1.40 \times 10^{316}$ \cite{Bays00}. But, according to a Littlewood's theorem, there exist infinitely many $x$ that violate the inequality, due to the specific distribution of non-trivial zeros $γ$ of the Riemann zeta function $ζ(s)$, encoded by the equation $li(x)-π(x)\approx \frac{\sqrt{x}}{\log x}[1+2 \sum_γ\frac{\sin (γ\log x)}γ]$ (1). If Riemann hypothesis (RH) holds, (i) may be replaced by the equivalent statement $li[ψ(x)]>π(x)$ (ii) due to Robin \cite{Robin84}. A statement similar to (i) was found by Chebyshev that $π(x;4,3)-π(x;4,1)>0$ (iii) holds for any $x<26861$ \cite{Rubin94} (the notation $π(x;k,l)$ means the number of primes up to $x$ and congruent to $l\mod k$). The {\it Chebyshev's bias}(iii) is related to the generalized Riemann hypothesis (GRH) and occurs with a logarithmic density $\approx 0.9959$ \cite{Rubin94}. In this paper, we reformulate the Chebyshev's bias for a general modulus $q$ as the inequality $B(x;q,R)-B(x;q,N)>0$ (iv), where $B(x;k,l)=li[ϕ(k)*ψ(x;k,l)]-ϕ(k)*π(x;k,l)$ is a counting function introduced in Robin's paper \cite{Robin84} and $R$ resp. $N$) is a quadratic residue modulo $q$ (resp. a non-quadratic residue). We investigate numerically the case $q=4$ and a few prime moduli $p$. Then, we proove that (iv) is equivalent to GRH for the modulus $q$.

title: Closed‐form buckling analysis of unsymmetrically laminated plates
Creators: name: Schreiber, Philip

description: The local stability of thin‐walled fibre‐reinforced plastic composite beams can be reduced to individual laminates using discrete plate theory. These individual plates receive a supporting effect from their surrounding structure, which is modelled with rotational restraints. In the present investigation, this buckling problem is described by a closed‐form solution. The energy‐based method works with the Rayleigh quotient and the principle of the stationary value of the elastic potential energy. For the analysis of unsymmetrically laminated plates, the classical laminated plate theory (CLPT) considers both the plate deflection and the in‐plane displacements. The first‐order shear deformation theory (FSDT) and third‐order shear deformation theory (TSDT) additionally describe the cross‐sectional rotations and thus take transverse shear deformations into account. In addition to the direct consideration of the bending‐extension couplings, these have also been investigated using the reduced bending stiffness (RBS) method. The investigation shows the influence of bending‐extension coupling on the stability of compressively loaded unsymmetrically laminated plates. Moreover, it is found that the transverse shear stiffness reduces the critical load at relatively high plate thicknesses. The closed‐form analytical solution and the RBS method show good agreement with finite element analyses. The presented closed‐form analytical methods provide explicit solutions for the critical compressive load of unsymmetric laminates under different boundary conditions. Due to the explicit solution, this method is significantly more computationally efficient than numerical, semi‐analytical or exact methods. The present methods are characterised by a simple applicability as well as a very high computational efficiency and are very suitable for preliminary design as well as optimisation of laminated structures.
