description: The use of chirally rotated boundary conditions provides a formulation of the Schroedinger functional that is compatible with automatic O(a)-improvement of Wilson fermions in the bulk. The elimination of bulk O(a) terms requires the non-perturbative tuning of the critical mass and one additional boundary counterterm. We present the results of such a tuning in the quenched approximation at three values of the renormalised gauge coupling and for a range of lattice spacings.

description: Based on calculations of the Stokes parameters for the Holweger-Mliller model atmosphere, we study sensitivity of the Fe I 525.02 nm line to some kinds of vertical and horizontal magnetic field inhomogeneity. A noticeable asymmetry is shown to appear in the V profile peaks when the vertical gradient is -0.4 mT/km, which is typical of some theoretical flux tube models. The asymmetry is most pronounced in a pure longitudinal magnetic field and at a low macroturbulent velocity. A similar effect is observed for the Q profile in nonlongitudinal fields as well. The Fe I 525.02 nm line is sensitive also to subtelescopic fields of mixed polarity like those observed by Stenflo in IR lines. We argue that the Wilson depression in small-scale flux tubes renders strong-field areas invisible at heliocentric angles greater than 60--65 degrees, since they are screened by surroundings with weaker magnetic fields.

Modifications to horn antennas which reduce beamwidth and back radiation
Creators: name: Jazi, Ahmad Safaai
Publisher: name: University of British Columbia
Year: 2010

description: Modifications to horn antennas through choke flanges and parabolic cylinder reflectors are investigated. The latter are introduced to narrow the beamwidth, increase the gain and reduce the back radiation without increasing the horn length. The geometrical diffraction theory concepts and the Kirchhoff method are employed in the calculation of E-plane patterns of modified horns. The Kirchhoff method is applied to determine the fields reflected from the chokes and parabolic reflectors in the forward region where the geometrical diffraction theory fails. Very close agreement is obtained between the computed and measured patterns in the front region. In the rear directions the general level of back radiation for choked horns and the approximate lobe structure for horns with reflectors are predicted. Modification of horns by chokes results in a considerable reduction in the back radiation, but only a slight improvement in the beamwidth and the gain. Modification by parabolic reflectors, on the other hand, will result in a significant reduction in the beamwidth and substantial increase in the on-axis gain if the focal length of the reflectors is optimal. Considerably lower back radiation is also achieved.

description: Supplementary scripts for "Pumice Raft Detection Using Machine-Learning on Multispectral Satellite Imagery"
Abstract:Most of Earth's volcanic eruptions occur underwater, and these submarine eruptions can significantly impact large-scale earth systems (e.g., enhancing local primary production by phytoplankton through supplying nutrients via hydrothermal fluids and discharged pumice rafts). However, detecting submarine eruptions is challenging due to their remote locations and eruption indicators' transient nature (e.g., floating pumice clasts, hydrothermal fluids). We can utilize global satellite imagery of 10-30 m resolution (e.g., Landsat~8, Sentinel-2) to detect new eruptions; however, the large data volumes make it challenging to systematically analyze satellite imagery on global or even regional scales. In this study, we address these challenges by developing a new semi-automated analysis framework to detect submarine eruptions through the supervised classification of satellite images on Google Earth Engine (GEE), which offers cloud-based data storage and computational resources. We present a case study using our methodology on satellite imagery from the Rabaul caldera region in Papua New Guinea. We find a large number of new unreported pumice rafts (in $\sim $16\% images from 2017--present). After analysis of the spatial pattern of raft sightings and ancillary geophysical and visual observations, we interpret that these rafts are not eruption fed. Instead, we posit that the observed rafts represent remobilization of pumice clasts from previous historical eruptions. This novel process of raft remobilization may be common at near-shore/partially submarine caldera systems (e.g., Rabaul, Krakatau) and has significant implications for new submarine eruption detection, volcanic stratigraphy, biological dispersal by rafts, as well as processes responsible for pumice flotation.

description: Nanoplastics are particulate matter measuring less than a millimeter, constitute a pressing global environmental challenge. These ubiquitous particles infiltrate both biotic and abiotic components of the ecosystem. The indiscriminate use of plastics in daily life, both in their primary form as nanoplastics (e.g., in cosmetics) and as secondary microplastics (resulting from the degradation of larger plastics) poses a substantial environmental concern.

description: A three-neutrino analysis of oscillation data is performed using the recent, more finely binned Super-K oscillation data, together with the CHOOZ, K2K, and MINOS data. The solar parameters, $Δ_{21}$ and $θ_{12}$, are fixed from a recent analysis, and $Δ_{32}$, $θ_{13}$, and $θ_{23}$ are varied. We utilize the full three-neutrino oscillation probability and an exact treatment of the Earth's MSW effect with a castle-wall density. By including terms linear in $θ_{13}$ and $\varepsilon := θ_{23} - π/4$, we find asymmetric errors for these parameters $θ_{13}=-0.07^{+0.18}_{-0.11}$ and $\varepsilon=0.03^{+0.09}_{-0.15}$. For $θ_{13}$, we see that the lower bound is primarily set by the CHOOZ experiment while the upper bound is determined by the low energy $e$-like events in the Super-K atmospheric data. We find that the parameters $θ_{13}$ and $\varepsilon$ are correlated -- the preferred negative value of $θ_{13}$ permits the preferred value of $θ_{23}$ to be in the second octant, and the true value of $θ_{13}$ affects the allowed region for $θ_{23}$.

A new leading-order operator is included. From our analysis we extract δm_N^{str}, the strong contribution to the neutron-proton mass difference. The value obtained, δm_N^{str} = 1.5 \pm 0.8 (exp.) \pm 0.5 (th.) MeV, is consistent with the result based on the Cottingham sum rule. This agreement provides a non-trivial test of our current understanding of the chiral structure of QCD.

description: I use cosmology examples to illustrate that the second law of thermodynamics is not old and tired, but alive and kicking, continuing to stimulate interesting research on really big puzzles. The question "Why is the entropy so low?" (despite the second law) suggests that our observable universe is merely a small and rather uniform patch in a vastly larger space stretched out by cosmological inflation. The question "Why is the entropy so high" (compared to the complexity required to describe many candidate "theories of everything") independently suggests that physical reality is much larger than the part we can observe.

A study of circular couette flow by laser doppler measurement techniques
Creators: name: Geach, Nigel Douglas Sinclair
Publisher: name: University of British Columbia
Year: 2010

description: A laser Doppler velocimeter is constructed and used to make flow measurements in circular Couette flow. The flow is created between concentric cylinders with a small gap-to-radius ratio, and measurements of the velocity profiles are made in both laminar and turbulent flow regimes. Distortion due to end effects is noted in the laminar case, but the turbulent case is shown to conform well to a three region model. A study of the mean velocity profiles allows estimates of skin friction and Reynolds stresses. Turbulent velocity fluctuations are also estimated from the laser Doppler technique, and their intensity compared with existing results for plane Couette flow.

description: In this work, a cosmological model inspired by string theory with Gauss-Bonnet term coupled to the fermionic field is taken into consideration. The self-interaction potential is considered as a combination of the scalar and pseudo-scalar invariants. Here the cosmological contribution of the coupling of Gauss-Bonnet term with a non-Dirac fermionic field--characterized by an \textit{interaction term}$L_{DG} ^2$-- is investigated. It is observed that the new type of coupling plays a significant role in the accelerating behavior of the universe. Specifically, in addition to the late time acceleration for the universe, $L_{DG} ^2$ produces an early decelerating behavior. The behavior of the equation-of-state parameter $(w)$ is such that it guarantees the stability of the theory.

Here we present our study of di-jet systematics comparing the measurements of associate yields and spectra in 200 GeV Au+Au and d+Au collisions in two different scenarios. We present Sum(pT) as an estimate for energy loss. First findings indicate little to no energy loss in the symmetric "2+1" scenario whereas model predictions are about 2 GeV.

description: Dust permeates the interstellar medium, reddening and polarizing background starlight, but dust properties vary with local environment. In order to characterize dust in a highly irradiated diffuse cloud, we measure the reddening and optical polarization towards 27 stars surrounding the mid-latitude $b$=$+$24$^{\circ}$ O9.2IV star $ζ$ Ophiuchi, using new optical spectroscopy and polarimetry. We incrementally deredden and depolarize with distance, allowing us to distinguish dust components along these sightlines. The data indicate three distinct dust populations: a foreground component characteristic of average Milky Way dust ($R_{\rm{V}}$$\approx$3.1, $d$$\lesssim$180 pc), a highly polarizing mid-distance component in the vicinity of $ζ$ Oph ($R_{\rm{V}}$$\approx$2.4, 200 pc$$9.1$E(B-V)$), implying a high degree of grain alignment and suggesting that the bulk of the polarization occurs in a small fraction of the volume. The large $R_{\rm{V}}$ in the distant component reveals that dust above the Galactic Plane ($z$$>$250 pc) may contain a greater fraction of large grains than the Milky Way average.

Modeling of Nucleation Processes

Publisher: name: arXiv
Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Nucleation is the onset of a first-order phase transition by which a metastable phase transforms into a more stable one. Such a phase transition occurs when an initial system initially in equilibrium is destabilized by the change of an external parameter like the temperature or the pressure. If the perturbation is small enough, the system does not become unstable but rather stays metastable. In diffusive transformations, the system then evolves through the nucleation, the growth and the coarsening of a second phase. Such a phase transformation is found in a lot of situations in materials science like condensation of liquid droplets from a supersaturated vapor, solidification, precipitation from a supersaturated solid solution, ... The initial stage of all these different processes can be well described within the same framework. Since its initial formulation in 1927 by Volmer, Weber and Farkas and its modification in 1935 by Becker and Döring the classical nucleation theory has been a suitable tool to model the nucleation stage in phase transformations. In this article, we first describe this theory. A kinetic approach, the cluster dynamics, can also be used to describe nucleation. This constitutes the second part of this article. The links as well as the difference between both descriptions are emphasized. Since its initial formulation, the classical nucleation theory has been enriched, so as to take into account the fact that clusters other than monomers can migrate and react. It has been also extended to multi-component systems. These generalizations of the initial formalism are also presented.

description: Recent work has shown that aside from the classical view of collisions by increasingly massive planetesimals, the accretion of mm- to m-sized 'pebbles' can also reproduce the mass-orbit distribution of the terrestrial planets. Here, we perform N-body simulations to study the effects of pebble accretion onto growing planetesimals of different diameters located in the inner Solar System. The simulations are run to occur during the lifetime of the gas disc while also simultaneously taking Jupiter's growth into account. We find that pebble accretion can increase the mass in the solid disc by at least a few times its initial mass with reasonable assumptions that pebbles fragment to smaller-sized grains at the snow line and that gas-disc-induced orbital migration effects are in force. Such a large contribution in mass by pebbles would seem to imply that the isotopic composition of the inner Solar System should be similar to the pebble source (i.e. outer Solar System). This implication appears to violate the observed nucleosynthetic isotopic dichotomy of the sampled Solar System. Thus, pebble accretion played little or no role in terrestrial planet formation.

description: We construct a family of elliptically fibered Calabi-Yau four-folds Y_4 for F-theory compactifications that realize SU(5) GUTs in the low-energy limit. The three-fold base X_3 of these fibrations is almost Fano and satisfies the topological criteria required to ensure that the U(1)_Y gauge boson remains massless, while allowing a decoupling of GUT and Planck scale physics. We study generic features of these models and the ability to engineer three chiral generations of MSSM matter. Finally, we demonstrate that it is relatively easy to implement the topological conditions required to reproduce certain successful features of local F-theory models, such as the emergence of flavor hierarchies.

Upper bounds on fault tolerance thresholds of noisy Clifford-based quantum computers

Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)

description: We consider the possibility of adding noise to a quantum circuit to make it efficiently simulatable classically. In previous works this approach has been used to derive upper bounds to fault tolerance thresholds - usually by identifying a privileged resource, such as an entangling gate or a non-Clifford operation, and then deriving the noise levels required to make it `unprivileged'. In this work we consider extensions of this approach where noise is added to Clifford gates too, and then `commuted' around until it concentrates on attacking the non-Clifford resource. While commuting noise around is not always straightforward, we find that easy instances can be identified in popular fault tolerance proposals, thereby enabling sharper upper bounds to be derived in these cases. For instance we find that if we take Knill's high threshold proposal together with the ability to prepare any possible state in the $XY$ plane of the Bloch sphere, then no more than 3.69% error-per-gate noise is sufficient to make it classical, and 13.71% of Knill's gamma noise model is sufficient. These bounds have been derived without noise being added to the decoding parts of the circuits. Introducing such noise in a toy example suggests that the present approach can be optimised further to yield tighter bounds.

description: Lightweight cryptography is a novel diversion from conventional cryptography that targets internet-of-things (IoT) platform due to resource constraints. In comparison, it offers smaller cryptographic primitives such as shorter key sizes, block sizes and lesser energy drainage. The main focus can be seen in algorithm developments in this emerging subject. Thus, verification is carried out based upon theoretical (mathematical) proofs mostly. Among the few available side-channel analysis studies found in literature, the highest percentage is taken by power attacks. PRESENT is a promising lightweight block cipher to be included in IoT devices in the near future. Thus, the emphasis of this paper is on lightweight cryptology, and our investigation shows unavailability of a correlation electromagnetic analysis (CEMA) of it. Hence, in an effort to fill in this research gap, we opted to investigate the capabilities of CEMA against the PRESENT algorithm. This work aims to determine the probability of secret key leakage with a minimum number of electromagnetic (EM) waveforms possible. The process initially started from a simple EM analysis (SEMA) and gradually enhanced up to a CEMA. This paper presents our methodology in attack modelling, current results that indicate a probability of leaking seven bytes of the key and upcoming plans for optimisation. In addition, introductions to lightweight cryptanalysis and theories of EMA are also included.

description: The way supermassive black holes (SMBH) in galactic centers accumulate their mass is not completely determined. At large scales, it is governed by galactic encounters, mass inflows connected to spirals arms and bars, or due to expanding shells from supernova (SN) explosions in the central parts of galaxies. The investigation of the latter process requires an extensive set of gas dynamical simulations to explore the muti-dimensional parameter space needed to frame the phenomenon. The aims of this paper are to extend our investigation of the importance of supernovae for inducing accretion onto a SMBH and carry out a comparison between the fully hydrodynamic code Flash and the much less computationally intensive code Ring, which uses the thin shell approximation. We simulate 3D expanding shells in a gravitational potential similar to that of the Galactic Center with a variety of homogeneous and turbulent environments. In homogeneous media, we find convincing agreement between Flash and Ring in the shapes of shells and their equivalent radii throughout their whole evolution until they become subsonic. In highly inhomogeneous, turbulent media, there is also a good agreement of shapes and sizes of shells, and of the times of their first contact with the central 1 pc sphere, where we assume that they join the accretion flow. The comparison supports the proposition that a SN occurring at a galactocentric distance of 5 pc typically drives 1 - 3 $M_\odot$ into the central 1 pc around the galactic center.

description: Central pattern generators (CPGs) in the spinal cord are motor circuits that oversee controlling rhythmic motor activities. CPGs are composed of different types of interneurons (INs) that interact with the motor neurons (MNs) to produce the patterns of MN activity that can coordinate limb and body movements. Elucidating how different populations of INs contribute to the spinal CPG circuitry in different ways is crucial to understanding neural circuit formation and function. In addition, to study how neural circuits, such as CPGs recruit muscle and dictate locomotion, a functional neuromuscular junction (NMJ) model is essential. As CPG and NMJ are both important components in understanding spinal locomotion, a cell-culture based model where it is possible to precisely modulate cellular, molecular, or transcriptional cues in well-defined time and space is highly desirable. In this study, an in vitro NMJ and a V2a IN-MN-myotube (MT) circuit were developed as model platforms to study CPGs using the unique cell lines developed previously in the lab: transgenic mouse embryonic stem cell (mESC) lines that can produce enriched cultures of Hb9⁺ MNs and excitatory Chx10⁺ V2a INs. We established and confirmed a co-culture condition for the formation of NMJ between the unique mESC-derived Hb9⁺ MNs and the C2C12-derived myotubes in vitro and qualitatively and quantitatively assessed the functional connection between the two cell types. Our platform was further advanced to include a model IN population, Chx10⁺ V2a INs to develop a platform that allows for the characterization of IN-MN connections in situ. The in vitro circuit was made by co-culturing V2a INs, MNs, and MTs in separate chambers of the microdevice that are connected with the microchannels. A co-culture protocol for all three cell types was established using different seeding strategies and medium combinations. To evaluate the possible network formation in the dissociated cultures of different cell types, microelectrode arrays (MEAs) were used. Utilizing the techniques developed in this project, a more systematic study of rhythm and pattern generation according to the IN composition can be carried out to further elucidate the role of each IN population in circuit formation and function

description: With the rapid growth of power market reform and power demand, the power transmission capacity of a power grid is approaching its limit, and the secure and stable operation of power systems becomes increasingly important. In particular, in modern power grids, the proportion of dynamic loads with fast recovery characteristics such as air conditioners, refrigerators, and industrial motors is increasing. As well as the increasing proportion of different forms of renewable energy in power systems. Therefore, short-term voltage stability (STVS) of power systems cannot be ignored. This article comprehensively sorts out the STVS problems of power systems from the perspective of data-driven methods and discusses existing challenges.

description: Adaptive filters are at the core of many signal processing applications, ranging from acoustic noise supression to echo cancelation, array beamforming, channel equalization, to more recent sensor network applications in surveillance, target localization, and tracking. A trending approach in this direction is to recur to in-network distributed processing in which individual nodes implement adaptation rules and diffuse their estimation to the network. When the a priori knowledge about the filtering scenario is limited or imprecise, selecting the most adequate filter structure and adjusting its parameters becomes a challenging task, and erroneous choices can lead to inadequate performance. To address this difficulty, one useful approach is to rely on combinations of adaptive structures. The combination of adaptive filters exploits to some extent the same divide and conquer principle that has also been successfully exploited by the machine-learning community (e.g., in bagging or boosting). In particular, the problem of combining the outputs of several learning algorithms (mixture of experts) has been studied in the computational learning field under a different perspective: rather than studying the expected performance of the mixture, deterministic bounds are derived that apply to individual sequences and, therefore, reflect worst-case scenarios. These bounds require assumptions different from the ones typically used in adaptive filtering, which is the emphasis of this overview article. We review the key ideas and principles behind these combination schemes, with emphasis on design rules. We also illustrate their performance with a variety of examples.

description: Multivariate Analysis (MVA) comprises a family of well-known methods for feature extraction which exploit correlations among input variables representing the data. One important property that is enjoyed by most such methods is uncorrelation among the extracted features. Recently, regularized versions of MVA methods have appeared in the literature, mainly with the goal to gain interpretability of the solution. In these cases, the solutions can no longer be obtained in a closed manner, and more complex optimization methods that rely on the iteration of two steps are frequently used. This paper recurs to an alternative approach to solve efficiently this iterative problem. The main novelty of this approach lies in preserving several properties of the original methods, most notably the uncorrelation of the extracted features. Under this framework, we propose a novel method that takes advantage of the l-21 norm to perform variable selection during the feature extraction process. Experimental results over different problems corroborate the advantages of the proposed formulation in comparison to state of the art formulations.

description: Supplementary scripts for "Pumice Raft Detection Using Machine-Learning on Multispectral Satellite Imagery"
Abstract:Most of Earth's volcanic eruptions occur underwater, and these submarine eruptions can significantly impact large-scale earth systems (e.g., enhancing local primary production by phytoplankton through supplying nutrients via hydrothermal fluids and discharged pumice rafts). However, detecting submarine eruptions is challenging due to their remote locations and eruption indicators' transient nature (e.g., floating pumice clasts, hydrothermal fluids). We can utilize global satellite imagery of 10-30 m resolution (e.g., Landsat 8, Sentinel-2) to detect new eruptions; however, the large data volumes make it challenging to systematically analyze satellite imagery on global or even regional scales. In this study, we address these challenges by developing a new semi-automated analysis framework to detect submarine eruptions through the supervised classification of satellite images on Google Earth Engine (GEE), which offers cloud-based data storage and computational resources. We present a case study using our methodology on satellite imagery from the Rabaul caldera region in Papua New Guinea. We find a large number of new unreported pumice rafts (in ~16% of images from 2017--present). After analysis of the spatial pattern of raft sightings and ancillary geophysical and visual observations, we interpret that these rafts are not eruption fed. Instead, we posit that the observed rafts represent remobilization of pumice clasts from previous historical eruptions. This novel process of raft remobilization may be common at near-shore/partially submarine caldera systems (e.g., Rabaul, Krakatau) and has significant implications for new submarine eruption detection, volcanic stratigraphy, biological dispersal by rafts, as well as processes responsible for pumice flotation.

description: In an effort to identify nearby and unusual cold objects in the solar neighborhood, we searched for previously unidentified moving objects using CatWISE2020 proper motion data combined with machine learning methods. We paired the motion candidates with their counterparts in 2MASS, UHS, and VHS. Then we searched for white dwarf, brown dwarf, and subdwarf outliers on the resulting color-color diagrams. This resulted in the discovery of 16 new dwarfs including two nearby M dwarfs (< 30 pc), a possible young L dwarf, a high motion early T dwarf and 3 later T dwarfs. This research represents a step forward in completing the census of the Sun's neighbors.

description: Background:
While children and adolescents typically experience mild symptoms during the acute phase of the COVID-19 infection, some may develop severe post-infectious symptoms. In our study Post-COVID Kids Bavaria we integrated somatic and psychiatric aspects of the post-COVID syndrome to provide a holistic description of symptoms, provide early treatment, and detect possible risk factors associated with post-infectious neurocognitive and emotional impairments.

Methods:
We conducted an observational study involving 85 pediatric patients aged 12–17 years (M = 12.48, 61.2% female) who had confirmed COVID-19 infections and were experiencing persistent symptoms for at least 4 weeks. Our neuropsychological assessment comprised infection-specific patient interviews, psychopathological examinations, emotional well-being and behavioral difficulty questionnaires, and (computerized) tests assessing concentration, attention, and memory skills. Additionally, patients underwent neurologic, pneumologic, gastrointestinal, and cardiologic assessments.

Results:
Overall, the majority of patients reported experiencing elevated levels of fatigue (82.4%), loss of motivation (72.9%), concentration and attention deficits (71.8%), a worsened mood (53%), and a higher level of anxiety (31.8%). The most common diagnosis was the post-COVID adjustment disorder (ICD-10 F43.2, U09.9!; 38.8%) followed by the post-COVID attention deficit disorder (ICD-10 F98.80, U09.9!; 23.5%). Neuropsychiatric evaluation primarily identified deficits in sustained attention. There was a significant association between somatic and psychiatric post-COVID diagnoses. Patients with allergies exhibited a higher risk of developing a post-COVID adjustment disorder. For the post-COVID attention deficit disorder, age, sex, obesity, pre-existing psychiatric diagnosis, and the virus variant were relevant factors.

Conclusions:
Our findings indicate a diverse array of neuropsychiatric symptoms associated with the post-COVID syndrome, emphasizing the interconnectedness between somatic and neuropsychiatric diagnoses. To optimize treatment, comprehensive strategies involving both somatic and psychiatric professionals are crucial for addressing the syndrome’s complexity and managing symptoms effectively.

description: We study returns in dynamical systems: when a set of points, initially populating a prescribed region, swarms around phase space according to a deterministic rule of motion, we say that the return of the set occurs at the earliest moment when one of these points comes back to the original region. We describe the statistical distribution of these "first--return times" in various settings: when phase space is composed of sequences of symbols from a finite alphabet (with application for instance to biological problems) and when phase space is a one and a two-dimensional manifold. Specifically, we consider Bernoulli shifts, expanding maps of the interval and linear automorphisms of the two dimensional torus. We derive relations linking these statistics with Renyi entropies and Lyapunov exponents.

A mathematical model for vortex-induced oscillation
Creators: name: Lee, Francis Ngai-Ho
Publisher: name: University of British Columbia
Year: 2010

description: The flow around a circular cylinder exhibiting vortex-induced oscillation is modelled by 2 potential vortices in a 2-dimensional, inviscid and irrotational flow. The lift on the cylinder is obtained from the general form of the Blasius equation. Pressure distribution is obtained from the pressure equation in a moving frame of reference. The lift expression is coupled to the dynamic equation of the cylinder. The phase and amplitude of oscillation are determined by the method of equivalent linearization. A relationship between amplitude of oscillation and strength of the vortices is proposed. Boot mean square pressure distribution at the Strouhal frequency on the surface of the oscillating cylinder is determined.
