Numerical studies of phase transitions in statistical and quantum lattice models provide crucial insights into the corresponding Conformal Field Theories (CFTs). In higher dimensions, comparing finite-volume numerical results to infinite-volume CFT data is facilitated by choosing the sphere S^{d-1} as the spatial manifold. Recently, the fuzzy sphere regulator [Zhu et al, Phys. Rev. X 13, 021009 (2023)] has enabled such studies with exact rotational invariance, yielding impressive agreement with known 3D Isi

Methane (CH4) and nitrous oxide (N2O) are potent greenhouse gases (GHGs) and are involved in ozone depletion. They are the second and third most significant GHGs contributing to climate change, with global warming potentials approximately 25 times and 300 times greater than CO2. The contribution of freshwater lakes to CH4 and N2O emissions remains debatable. Oxygen-rich subsurface waters are recognized as hotspots of metalimnetic CH4 flux, while oxygen-driven diffusion in deep water columns is expected to e

Aerosols have a significant impact on Earth’s climate and human health. The spatial and temporal distribution of aerosols is very heterogeneous and therefore difficult to constrain in atmospheric models. In situ measurements are very useful to shed light on aerosols’ distribution and processes. However, many questions regarding aerosols remain open. The vertical distribution of aerosol particles represents key information to understand their effect on climate and health, however vertical in situ observation

We propose a novel multi-task neural network-based approach for joint sound source localization and speech/non-speech classification in noisy environments. The network takes raw short time Fourier transform as input and outputs the likelihood values for th ...

We propose to use neural networks for simultaneous detection and localization of multiple sound sources in human-robot interaction. In contrast to conventional signal processing techniques, neural network-based sound source localization methods require few ...

In the first part, we first introduce steganography (in chapter 1) not in the usual context of information security, but as a method to piggyback data on top of some content. We then focus on audio steganography and propose a new steganographic scheme in chapter 2 as well as a model for the noisy, analog communication channel we are considering (in section 3.2). The method we use is based on signal mixing, the science of constructing vectors in a way that their sum can then be split back into the original c

Process for producing a briquette containing carbon carriers (2): mixing the carbon carriers (2) together with a binder system (3) with introduction of steam and the mixture obtained is pressed to form briquettes. At least one of drying carbon carriers (2) ...

We cast the under-determined convolutive speech separation as sparse approximation of the spatial spectra of the mixing sources. In this framework we compare and contrast the major practical algorithms for structured sparse recovery of speech signal. Specific attention is paid to characterization of the measurement matrix. We first propose how it can be identified using the Image model of multi-path effect where the acoustic parameters are estimated by localizing a speaker and its images in a free space mod

The ability of human auditory systems to focus on one signal and ignore other signals in an auditory scene where several auditory events are taking place, often referred to as cocktail-party effect, is a key to localization of sound sources. This ability is partly made possible by interaural cues – Interaural Time Differences (ITDs) and Interaural Level Differences (ILDs) – between the input ear signals that assist the estimation of source azimuth angles, and separation of the signal of the desired directio

Extremely sensitive protein detection is crucial for early diagnosis and monitoring of diseases. Present day’s limit of detection for an antibody-antigen recognition-based immunoassay in serum without having to use special target antigen amplification tech ...

Several regional augmentation GNSS systems (like SBAS) are already fully operational and other are under development with new frequencies and signals on the way. Therefore, it becomes imperative to guarantee for all GNSS users the compatibility, interoperability and interchangeability between all these systems. The goal is to ensure that the user’s multi-mode receiver can choose and mix signals from different GNSS and SBAS systems to achieve more availability, accuracy and robustness. Attaining that objecti

The human auditory system is comprised of specialized but interacting anatomic and functional pathways encoding object, spatial, and temporal information. We review how learning-induced plasticity manifests along these pathways and to what extent there are common mechanisms subserving such plasticity. A first series of experiments establishes a temporal hierarchy along which sounds of objects are discriminated along basic to fine-grained categorical boundaries and learned representations. A widespread netwo

Driven by the commercial success of recombinant biopharmaceuticals, there is an increasing demand for novel, cost-effective mammalian cell culture bioreactor systems for the production of biologicals requiring mammalian protein processing. Recently, orbita ...

Laser-induced fluorescence, resonant two-photon ionization, UV-UV hole burning, UV depletion, and single vibronic level fluorescence (SVLF) spectra of jet-cooled diphenylmethane (DPM) have been recorded over the 37 300 - 38 400 cm(-1) region that encompass ...

The precedence effect describes perceived localization dominance of a sound event over a sound event arriving 2 to 50 ms later. A related effect, occurring with sequences of 100 ms long narrowband noise bursts, is described. In contrast to classical precedence effect experiments with two sound sources, the noise bursts are emitted from three frontal positions. Depending on the length of pauses inserted into the sequence, the center source is significantly less localizable than the side sources. An equivalen

The spatialization of the sound field in a room is studied, in particular the evolution of room impulse responses as a function of their spatial positions. It was observed that the multidimensional spectrum of the solution of the wave equation has an almost bandlimited character. Therefore, sampling and interpolation can easily be applied using signals on an array. The decay of the spectrum is studied on both temporal and spatial frequency axes. The influence of the decay on the performance of the interpola

Based on binaural signals, i.e. the signals observed at the two ears, a listener can localize and recognize different sound sources and then focus on one of these. For decades, researchers have tried to invent a machine that can do the same under similar conditions. Despite all the efforts, the human auditory system is, by far, superior to any machine that has been devised. The topic of this thesis is computational techniques for the localization and separation of sources in binaural signals. In order to gi

The Buss-Kneader has proven to be a suitable reactor for the polymerization of acrylates. In this second part, the polymerization of methyl methacrylate and the ter- polymerization of methyl methacrylate (MMA), hydroxyethyl methacrylate and n-butylmethacrylate is carried out in a pilot Buss-Kneader. The reactor had to be pressurized up to about 10 bars to avoid evaporation of MMA. Instabilities in output rate and temperature profiles were observed as a result of fluctuating the pressures. Because of good mi

The role of the confinement potential symmetry on the electronic and optical properties of quantum mires is systematically studied. In a wide class of quantum mires with mirror symmetry we evidence a new set of optical transitions resulting both from band mixing and Ct, symmetry breaking at zone center. Several kinds of quasi-one-dimensional excitons are predicted as well as their specific dipole coupling. Even for ultralow C-1 symmetry we find independent excitons with distinct polarization selection rules

The electronic states in the conduction and valence bands of quantum wires are studied by means of the effective mass hamiltonian and the Luttinger hamiltonian. The band mixing effects due to the wire geometry are fully taken into account by an accurate finite element solution of the resulting Schrodinger equations. The quantum wire profiles measured by transmission electron microscopy are used. The comparison of theoretical results with photoluminescence excitation spectra of various nanostructures yields
