The deconvolution of teleseismic recordings
Creators: name: Clayton, Robert W.
Publisher: name: University of British Columbia
Year: 2010

description: A method is presented for the deconvolution of a suite of teleseismic recordings of the same event. The suite must be restricted in azimuthal and delta ranges in order that the assumption of source stationarity can be made. The source is estimated by averaging the log amplitude and phase spectra of the recordings. This method of source estimation uses the redundant source information contained in secondary arrivals. The necessary condition for this estimator to resolve the source wavelet is that the travel times of the various secondary arrivals be evenly distributed with respect to the initial arrivals. The actual deconvolution of the seismograms is done by spectral division with two modifications. The first is the introduction of a minimum allowable source spectral amplitude termed the waterlevel (Helmberger and Wiggins, 1971). This parameter constrains the gain of the deconvolution filter in regions where the seismogram has little or no information, and also trades-off arrival time resolution with arrival amplitude resolution. The second modification, designed to increase the time domain resolution of the deconvolution, is the extension of the transmission path impulse response spectrum beyond its optimal passband (the passband of the seismograms). The justification for the extension lies in the fact that the impulse response is "impulsive" by nature which means its spectrum is not band-limited. Thus, the impulse response is best represented by a continuous spectrum rather than one which is set to zero outside the optimal passband. The actual prediction is done by an recursive application of a unit-step prediction operator determined by Burg's maximum entropy algorithm (Burg, 1967). The envelopes of the deconvolution are used to detect the presence of phase shifted arrivals. The source estimator and deconvolution method are applied to three examples: Kern County (16/10/62) , West Australia (24/3/70) , and Novaya Zemlya (14/10/69). Source estimation by homomorphic transforms (Ulrych, 197 1) is also discussed in this thesis. This method of source estimation was found to be of limited use because of the invalidity of the low quefrency [sic] assumption that must be applied (Ulrych, 1971), and the phase instabilities of the transform itself.

description: The phi(1020) radiative decays form a good playground for study of the low-lying a0(980) and f0(980) scalar mesons. The complicated interplay of kaon loop mechanism, isoscalar meson mixing and momentum dependence of the effective couplings manifests itself in the invariant mass distributions in the phi(1020) -> pi0 pi0 gamma and pi eta gamma spectra. These distributions are fitted in framework of Resonance Chiral Theory.

description: This research presents an innovative approach to enhancing ransomware detection by leveraging Windows API calls and PE header information to develop precise signatures capable of identifying ransomware families. Our methodology introduces a novel application of hierarchical clustering using the HDBSCAN algorithm, in conjunction with the Jaccard similarity metric, to cluster ransomware into discrete families and generate corresponding signatures. This technique, to our knowledge, marks a pioneering effort in applying hierarchical density-based clustering to over 1.1 million malicious samples, specifically focusing on ransomware and using the clusters to automatically generate signatures. We show that identifying unique Windows API function patterns within these clusters enables the differentiation and characterization of various ransomware families. Furthermore, we conducted a case study focusing on the distinctive function combinations within prominent ransomware families such as GandCrab, WannaCry, Cerber, Gotango, and CryptXXX, unveiling unique behaviors and API function usage patterns. Our scalable implementation demonstrates the ability to efficiently cluster large volumes of malicious files and automatically generate robust, actionable function signatures for each. Validation of these signatures on an independent malware dataset yielded a precision rate of 98.34% and specificity rate of 99.72%, affirming their effectiveness in detecting known ransomware families with minimal error. These findings underscore the potential of our methodology in bolstering cybersecurity defenses against the evolving landscape of ransomware threats

description:  

Metabarcoding of invertebrate-derived DNA (iDNA) has proven to be an excellent tool for assessing terrestrial mammal diversity. While fly iDNA-based monitoring can detect a wide range of mammals, including rare, small, and cryptic species, a major constraint to wider adoption has been the time and costs associated with sample processing. 

Here we explored the effectiveness of bulk fly iDNA extraction methods which increase the pooling of flies by an order of magnitude over currently used extraction methods. One extraction method involved removing a single leg per fly from many different flies, pooling these legs, and destructively extracting DNA from the pool (Nflies legs per pool = 105). The other method involved non-destructively extracting DNA from a large pool of entire flies (Nflies per pool = 105). We tested these methods on flies collected at eight sites, representing three different habitats across five countries in sub-Saharan Africa (Nflies/site = 105; Nflies total = 840). We compared the mammal species detected using metabarcoding of these extracts with extracts generated using an approach that is currently widely used in the field, the  cost- and labor-intensive destructive extraction of small pools of entire flies (Nflies per pool = 7; Nflies per site = 105 flies). 

The non-destructive extraction from large pools of entire flies detected a greater number of mammals (Nspecies detections total = 59; x̄species/site = 7.4; range = 1 to 12) than the destructive extraction from large pools of fly legs (Nspecies detections total = 15; x̄species/site = 1.9; range = 2 to 3), while detecting a similar number of mammals as the destructive extraction from small pools of entire flies (Nspecies detections total = 67; x̄species/site = 8.4; range = 5 to 15). Our findings indicate that the non-destructive extraction of large pools of entire fly bodies has the potential to streamline and reduce costs of fly iDNA extraction. We hope this will further promote the use of fly iDNA in large-scale terrestrial biomonitoring efforts.

description: Astronomical observations reveal that protoplanetary disks around young stars commonly have ring- and gap-like structures in their dust distributions. These features are associated with pressure bumps trapping dust particles at specific locations, which simulations show are ideal sites for planetesimal formation. Here we show that our Solar System may have formed from rings of planetesimals -- created by pressure bumps -- rather than a continuous disk. We model the gaseous disk phase assuming the existence of pressure bumps near the silicate sublimation line (at $T \sim$1400~K), water snowline (at $T \sim$170~K), and CO-snowline (at $T \sim$30~K). Our simulations show that dust piles up at the bumps and forms up to three rings of planetesimals: a narrow ring near 1~au, a wide ring between $\sim$3-4~au and $\sim$10-20~au, and a distant ring between $\sim$20~au and $\sim$45~au. We use a series of simulations to follow the evolution of the innermost ring and show how it can explain the orbital structure of the inner Solar System and provides a framework to explain the origins of isotopic signatures of Earth, Mars and different classes of meteorites. The central ring contains enough mass to explain the rapid growth of the giant planets' cores. The outermost ring is consistent with dynamical models of Solar System evolution proposing that the early Solar System had a primordial planetesimal disk beyond the current orbit of Uranus.

description: Online health information sources (OHIS) offer potential for improving access to health information especially in areas with limited healthcare infrastructure. However, OHIS predominantly originates from Western societies potentially ignoring the specific needs and cultural contexts of diverse populations. There is limited research on the global suitability of OHIS content. This study explores the global relevance of OHIS for diverse populations through a case study examining user experiences of Nigerians living in multiple countries. Findings reveal OHIS usage patterns are influenced by the country of residence and local health services availability. The study highlights the need for culturally inclusive OHIS content to ensure equitable health information access globally. Ultimately, for OHIS to serve a global audience effectively, there needs to be reliable information sources that acknowledge and cater to different users' cultural backgrounds, including prevalent health issues, medical practices, beliefs, languages, and healthcare expectations.

description: There is a dire need to enable an early diagnosis system to enhance the therapeutic outcome for patients by applying a medical image analysis application. This study proposes an improved auto-encoder model by integrating Squeeze and Excitation (SE) blocks on the different phases of the model for semantic segmentation, which U-Net inspires. We redesigned the model's skip-connection by utilizing Residual Squeez and Excitation (RSE) by employing SE block in a residual way to reduce the semantic gaps and discrepancy between encoder and decoder features. Then, we integrate the Dense Squeeze and Excitation (DSE) block in the model's bottleneck with a densely connected structure. We increase the model's accuracy compared to vanilla U-Net by integrating the discussed module in the model to enhance its capability for feature extraction and obtain more high-level features from the input feature. To evaluate our model's performance, we conducted our experiment on the 2018 Data Science Bowl dataset and compared it with the different approaches that are inspired by U-Net. Our proposed model achieved the Dice and IoU of 92.15% and 85.92% , respectively, surpassing most of the current stateof-the-art models.

description: Non-local thermodynamic equilibrium (NLTE) line formation for neutral and singly-ionized iron is considered through a range of stellar parameters characteristic of cool stars. A comprehensive model atom for Fe I and Fe II is presented. Our NLTE calculations support the earlier conclusions that the statistical equilibrium (SE) of Fe I shows an underpopulation of Fe I terms. However, the inclusion of the predicted high-excitation levels of Fe I in our model atom leads to a substantial decrease in the departures from LTE. As a test and first application of the Fe I/II model atom, iron abundances are determined for the Sun and four selected stars with well determined stellar parameters and high-quality observed spectra. Within the error bars, lines of Fe I and Fe II give consistent abundances for the Sun and two metal-poor stars when inelastic collisions with hydrogen atoms are taken into account in the SE calculations. For the close-to-solar metallicity stars Procyon and $β$ Vir, the difference (Fe II - Fe I) is about 0.1 dex independent of the line formation model, either NLTE or LTE. We evaluate the influence of departures from LTE on Fe abundance and surface gravity determination for cool stars.

description: The proprietary nature of existing Content Delivery Networks (CDNs) means they are closed and do not naturally cooperate. A CDN is expected to provide high performance Internet content delivery through global coverage, which might be an obstacle for new CDN providers, as well as affecting commercial viability of existing ones. Finding ways for distinct CDNs to coordinate and cooperate with other CDNs is necessary to achieve better overall service, as perceived by end-users, at lower cost. In this paper, we present an architecture to support peering arrangements between CDNs, based on a Virtual Organization (VO) model. Our approach promotes peering among providers, while upholding user perceived performance. This is achieved through proper policy management of negotiated Service Level Agreements (SLAs) between peers. We also present a Quality of Service (QoS)-driven performance modeling approach for peering CDNs in order to predict the user perceived performance. We show that peering between CDNs upholds user perceived performance by satisfying the target QoS. The methodology presented in this paper provides CDNs a way to dynamically distribute user requests to other peers according to different request-redirection policies. The model-based approach helps an overloaded CDN to return to a normal state by offloading excess requests to the peers. It also assists in making concrete QoS guarantee for a CDN provider. Our approach endeavors to achieve scalability and resource sharing among CDNs through effective peering in a user transparent manner, thus evolving past the current landscape where non-cooperative and distinct CDNs exist.

description: Agentic Generative AI, powered by Large Language Models (LLMs) with Retrieval-Augmented Generation (RAG), Knowledge Graphs (KGs), and Vector Stores (VSs), represents a transformative technology applicable to specialized domains such as legal systems, research, recommender systems, cybersecurity, and global security, including proliferation research. This technology excels at inferring relationships within vast unstructured or semi-structured datasets. The legal domain here comprises complex data characterized by extensive, interrelated, and semi-structured knowledge systems with complex relations. It comprises constitutions, statutes, regulations, and case law. Extracting insights and navigating the intricate networks of legal documents and their relations is crucial for effective legal research. Here, we introduce a generative AI system that integrates RAG, VS, and KG, constructed via Non-Negative Matrix Factorization (NMF), to enhance legal information retrieval and AI reasoning and minimize hallucinations. In the legal system, these technologies empower AI agents to identify and analyze complex connections among cases, statutes, and legal precedents, uncovering hidden relationships and predicting legal trends-challenging tasks that are essential for ensuring justice and improving operational efficiency. Our system employs web scraping techniques to systematically collect legal texts, such as statutes, constitutional provisions, and case law, from publicly accessible platforms like Justia. It bridges the gap between traditional keyword-based searches and contextual understanding by leveraging advanced semantic representations, hierarchical relationships, and latent topic discovery. This framework supports legal document clustering, summarization, and cross-referencing, for scalable, interpretable, and accurate retrieval for semi-structured data while advancing computational law and AI.

The temperature-dependent resistivity ρ(T) reveals a clear signature of LA phonon scattering, yielding a deformation potential D = 7.8+/-0.5 eV.

Motion control and real-time systems: an approach to trajectory rebuilding in non-deterministic networks
Creators: name: Spera, Manuel <1978>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2008
Subjects: ING-INF/04 Automatica

description: Motion control is a sub-field of automation, in which the position and/or velocity of machines
are controlled using some type of device. In motion control the position, velocity, force, pressure,
etc., profiles are designed in such a way that the different mechanical parts work as an harmonious
whole in which a perfect synchronization must be achieved.
The real-time exchange of information in the distributed system that is nowadays an industrial
plant plays an important role in order to achieve always better performance, better effectiveness
and better safety. The network for connecting field devices such as sensors, actuators, field controllers
such as PLCs, regulators, drive controller etc., and man-machine interfaces is commonly
called fieldbus.
Since the motion transmission is now task of the communication system, and not more of kinematic
chains as in the past, the communication protocol must assure that the desired profiles, and
their properties, are correctly transmitted to the axes then reproduced or else the synchronization
among the different parts is lost with all the resulting consequences.
In this thesis, the problem of trajectory reconstruction in the case of an event-triggered communication
system is faced.
The most important feature that a real-time communication system must have is the preservation
of the following temporal and spatial properties: absolute temporal consistency, relative
temporal consistency, spatial consistency.
Starting from the basic system composed by one master and one slave and passing through
systems made up by many slaves and one master or many masters and one slave, the problems
in the profile reconstruction and temporal properties preservation, and subsequently the synchronization
of different profiles in network adopting an event-triggered communication system, have
been shown. These networks are characterized by the fact that a common knowledge of the global
time is not available. Therefore they are non-deterministic networks. Each topology is analyzed
and the proposed solution based on phase-locked loops adopted for the basic master-slave case
has been improved to face with the other configurations.

description: In this paper we introduce a new problem within the growing literature of interpretability for convolution neural networks (CNNs). While previous work has focused on the question of how to visually interpret CNNs, we ask what it is that we care to interpret, that is, which layers and neurons are worth our attention? Due to the vast size of modern deep learning network architectures, automated, quantitative methods are needed to rank the relative importance of neurons so as to provide an answer to this question. We present a new statistical method for ranking the hidden neurons in any convolutional layer of a network. We define importance as the maximal correlation between the activation maps and the class score. We provide different ways in which this method can be used for visualization purposes with MNIST and ImageNet, and show a real-world application of our method to air pollution prediction with street-level images.

description: We use velocity and metallicity information from SDSS and SEGUE stellar spectroscopy to fit an orbit to the narrow $63^\circ$ stellar stream of Grillmair and Dionatos. The stars in the stream have a retrograde orbit with eccentricity $e = 0.33$ (perigalacticon of 14.4 kpc and apogalacticon of 28.7 kpc) and inclination approximately $i \sim 35^\circ$. In the region of the orbit which is detected, it has a distance of about 7 to 11 kpc from the Sun. Assuming a standard disk plus bulge and logarithmic halo potential for the Milky Way stars plus dark matter, the stream stars are moving with a large space velocity of approximately $276 \rm km s^{-1}$ at perigalacticon. Using this stream alone, we are unable to determine if the dark matter halo is oblate or prolate. The metallicity of the stream is [Fe/H] $= -2.1\pm0.1$. Observed proper motions for individual stream members above the main sequence turnoff are consistent with the derived orbit. None of the known globular clusters in the Milky Way have positions, radial velocities, and metallicities that are consistent with being the progenitor of the GD-1 stream.

description: The rooting procedure commonly used with staggered fermions does not correctly treat non-perturbative effects associated with gauge field topology. In practice these effects are small for the physics of flavor non-singlet particles. However large uncontrolled systematic errors are expected for flavor singlet issues, such as the mass of the eta prime meson. While the relative speed of the algorithm in large scale simulations may justify its use, the method is an approximation and should not be promoted as a first principles approach to the strong interactions.

description: The wireless medium contains domain-specific information that can be used to complement and enhance traditional security mechanisms. In this paper we propose ways to exploit the fact that, in a typically rich scattering environment, the radio channel response decorrelates quite rapidly in space. Specifically, we describe a physical-layer algorithm that combines channel probing (M complex frequency response samples over a bandwidth W) with hypothesis testing to determine whether current and prior communication attempts are made by the same user (same channel response). In this way, legitimate users can be reliably authenticated and false users can be reliably detected. To evaluate the feasibility of our algorithm, we simulate spatially variable channel responses in real environments using the WiSE ray-tracing tool; and we analyze the ability of a receiver to discriminate between transmitters (users) based on their channel frequency responses in a given office environment. For several rooms in the extremities of the building we considered, we have confirmed the efficacy of our approach under static channel conditions. For example, measuring five frequency response samples over a bandwidth of 100 MHz and using a transmit power of 100 mW, valid users can be verified with 99% confidence while rejecting false users with greater than 95% confidence.

Hybrid Methods for Resource Allocation and Scheduling Problems in Deterministic and Stochastic Environments
Creators: name: Lombardi, Michele <1980>

Subjects: ING-INF/05 Sistemi di elaborazione delle informazioni

description: This work presents exact, hybrid algorithms for mixed resource Allocation and Scheduling problems; in general terms, those consist into assigning over time finite capacity resources to a set of precedence connected activities.

The proposed methods have broad applicability, but are mainly motivated by applications in the field of Embedded System Design. In particular, high-performance embedded computing recently witnessed the shift from single CPU platforms with application-specific accelerators to programmable Multi Processor Systems-on-Chip (MPSoCs). Those allow higher flexibility, real time performance and low energy consumption, but the programmer must be able to effectively exploit the platform parallelism. This raises interest in the development of algorithmic techniques to be embedded in CAD tools; in particular, given a specific application and platform, the objective if to perform optimal allocation of hardware resources and to compute an execution schedule.

On this regard, since embedded systems tend to run the same set of applications for their entire lifetime, off-line, exact optimization approaches are particularly appealing. Quite surprisingly, the use of exact algorithms has not been well investigated so far; this is in part motivated by the complexity of integrated allocation and scheduling, setting tough challenges for ``pure'' combinatorial methods. The use of hybrid CP/OR approaches presents the opportunity to exploit mutual advantages of different methods, while compensating for their weaknesses.

In this work, we consider in first instance an Allocation and Scheduling problem over the Cell BE processor by Sony, IBM and Toshiba; we propose three different solution methods, leveraging decomposition, cut generation and heuristic guided search. Next, we face Allocation and Scheduling of so-called Conditional Task Graphs, explicitly accounting for branches with outcome not known at design time; we extend the CP scheduling framework to effectively deal with the introduced stochastic elements. Finally, we address Allocation and Scheduling with uncertain, bounded execution times, via conflict based tree search; we introduce a simple and flexible time model to take into account duration variability and provide an efficient conflict detection method.

The proposed approaches achieve good results on practical size problem, thus demonstrating the use of exact approaches for system design is feasible. Furthermore, the developed techniques bring significant contributions to combinatorial optimization methods.

description: Lo scopo dello studio è un'analisi comparativa degli impatti ambientali, calcolati utilizzando la metodologia del Life Cycle Assessment, della fase agricola di 9 colture dedicate (lignocellulosiche, oleaginose e cereali) da biomassa, con diifferenti destinazioni energetiche (biocarburanti di I e II generazione ed energia elettrica). E' infine stata eseguita un'analisi "from cradle to grave" considerando anche le diverse tecnice di trasformazione possibili, con dati bibliografici. Sotto tutti i profili (impatto per ettaro, impatto per unità energetica generata, e impatto totale della filiera, risulta un netto vantaggio delle coltrue lignocellulosiche, e fra queste specialmente le poliennali.

description: Thermal infrared (IR, 10.5 – 12.5 m) images from the Meteosat Visible and Infrared Imager (MVIRI) of cold cloud episodes (cloud top brightness temperature < 241 K) are used as a proxy of precipitating clouds to derive a warm season (May-August) climatology of their coherency, duration, span, and speed over Europe and the Mediterranean. The analysis focuses over the 30°-54°N, 15°W-40°E domain in May-August 1996-2005.
Harmonic analysis using discrete Fourier transforms is applied together with a statistical analysis and an investigation of the diurnal cycle.
This study has the objective to make available a set of results on the propagation dynamics of the cloud systems with the aim of assist numerical modellers in improving summer convection parameterization.
The zonal propagation of cold cloud systems is accompanied by a weak meridional component confined to narrow latitude belts. The persistence of cold clouds over the area evidences the role of orography, the Pyrenees, the Alps, the Balkans and Anatolia. A diurnal oscillation is found with a maximum marking the initiation of convection in the lee of the mountains and shifting from about  1400 UTC at 40°E to 1800 UTC at 0°. A moderate eastward propagation of the frequency maximum from all mountain chains across the domain exists and the diurnal maxima are completely suppressed west of 5°W. The mean power spectrum of the cold cloud frequency distribution evidences a period of one day all over Europe disappearing over the ocean (west of 10°W).  Other maxima are found in correspondence of 6 to 10 days in the longitudes from 15° W to 0° and indicate the activity of the westerlies with frontal passage over the continent.  Longer periods activities (from 15 up to 30 days) were stronger around 10° W and from 5° W to 15° E and are likely related to the Madden Julian Oscillation influence. The maxima of the diurnal signal are in phase with the presence of elevated terrain and with land masses.
A median zonal phase speed of 16.1 ms-1 is found for all events ≥ 1000 km and ≥ 20 h and a full set of results divided by years and recurrence categories is also presented.

description: Recoupling coefficients (3nj symbols) are unitary transformations between binary coupled eigenstates of N=(n+1) mutually commuting SU(2) angular momentum operators. They have been used in a variety of applications in spectroscopy, quantum chemistry and nuclear physics and quite recently also in quantum gravity and quantum computing. These coefficients, naturally associated to cubic Yutsis graphs, share a number of intriguing combinatorial, algebraic, and analytical features that make them fashinating objects to be studied on their own. In this paper we develop a bottom--up, systematic procedure for the generation of 3nj from 3(n-1)j diagrams by resorting to diagrammatical and algebraic methods. We provide also a novel approach to the problem of classifying various regimes of semiclassical expansions of 3nj coefficients (asymptotic disentangling of 3nj diagrams) for n > 2 by means of combinatorial, analytical and numerical tools.

Influence of flow confinement on the drag force on a static cylinder

description: The influence of confinement on the drag force $F$ on a static cylinder in a viscous flow inside a rectangular slit of aperture $h_0$ has been investigated from experimental measurements and numerical simulations. At low enough Reynolds numbers, $F$ varies linearly with the mean velocity and the viscosity, allowing for the precise determination of drag coefficients $λ_{||}$ and $λ_{\bot}$ corresponding respectively to a mean flow parallel and perpendicular to the cylinder length $L$. In the parallel configuration, the variation of $λ_{||}$ with the normalized diameter $β= d/h_0$ of the cylinder is close to that for a 2D flow invariant in the direction of the cylinder axis and does not diverge when $β= 1$. The variation of $λ_{||}$ with the distance from the midplane of the model reflects the parabolic Poiseuille profile between the plates for $β\ll 1$ while it remains almost constant for $β\sim 1$. In the perpendicular configuration, the value of $λ_{\bot}$ is close to that corresponding to a 2D system only if $β\ll 1$ and/or if the clearance between the ends of the cylinder and the side walls is very small: in that latter case, $λ_{\bot}$ diverges as $β\to 1$ due to the blockage of the flow. In other cases, the side flow between the ends of the cylinder and the side walls plays an important part to reduce $λ_{\bot}$: a full 3D description of the flow is needed to account for these effects.
Crystal structure of spessartine and andradite at elevated temperatures

description: Single crystal x-ray intensity data have been collected with a manual diffractometer utilizing flat-cone geometry for a spessartine from Minas Gervais, Brazil at 25°, 350°, 575° and 850°C and for an andradite from Valmalen, Italy at 25°, 350°, 575° and 850°C. Weighted anisotropic least-squares refinements in space group Ia3d resulted in residual (R) factors ranging from 0.019 to 0.029. The refinements indicate that all of the positional parameters of the oxygen atom in andradite vary during thermal expansion. The x and y positional parameters of oxygen in spessartine likewise vary during thermal expansion while the z positional parameter remains essentially constant. Linear thermal expansion coefficients of the cell edges are 0.632(53) x 10⁻⁵°C⁻¹ and 0.764(23) x 10⁻⁵°C⁻¹ for spessartine and andradite, respectively. A high linear dependence is shown to exist for the cell edges of members of the silicate garnet solid solution as a function of temperature and composition collectively. Si-0 interatomic distances in both spessartine and andradite (uncorrected for thermal displacement) show a zero or slightly negative expansion while the Mn-0 and Al-0 interatomic distances of spessartine and the Ca-0 and Fe-0 interatomic distances of andradite show significant positive expansions as a function of increasing temperature. The rates of expansion of the Al-0, Mn(l)-0(4), and Mn(2)-0(4) interatomic distances in spessartine are 1.61(30) x 10⁻⁵Å°C⁻¹, 2.12(28) x 10⁻⁵Å°C⁻¹, and 3.28(31) x 10⁻⁵Å°C⁻¹, respectively. The rates of expansion of the Fe-0, Ca(l)-0(4) and Ca(2)-0(4) interatomic distances in andradite are 2.94(44) x 10⁻⁵Å°C⁻¹, 2.31(20) x 10⁻⁵Å°C⁻¹, and 3.28(13) x 10⁻⁵Å°C⁻¹, respectively. Relations between these values and the values reported for pyrope and grossularite (Meagher, 1975) as well as the concomitant polyhedral adjustments are considered in detail. In both spessartine and andradite, the shared octahedral edge increases at a greater rate than does the unshared octahedral edge and the X(2)-0(4) distance increases at a greater rate than does the X(l)-0(4) interatomic distance during thermal expansion. The spessartine garnet structure facilitates these variations mainly by rotation of the essentially rigid SiO₄ tetrahedron while the andradite garnet structure facilitates the same variations mainly by a distortion of the SiO₄ tetrahedron. The SiO₄ tetrahedron of andradite becomes more ideal as a function of increasing temperature.

A Comparative Evaluation of Additive Separability Tests for Physics-Informed Machine Learning

description: Many functions characterising physical systems are additively separable. This is the case, for instance, of mechanical Hamiltonian functions in physics, population growth equations in biology, and consumer preference and utility functions in economics. We consider the scenario in which a surrogate of a function is to be tested for additive separability. The detection that the surrogate is additively separable can be leveraged to improve further learning. Hence, it is beneficial to have the ability to test for such separability in surrogates. The mathematical approach is to test if the mixed partial derivative of the surrogate is zero; or empirically, lower than a threshold. We present and comparatively and empirically evaluate the eight methods to compute the mixed partial derivative of a surrogate function.

description: This paper deals with the optimal path placement for a manipulator based on energy consumption. It proposes a methodology to determine the optimal location of a given test path within the workspace of a manipulator with minimal electric energy used by the actuators while taking into account the geometric, kinematic and dynamic constraints. The proposed methodology is applied to the Orthoglide~3-axis, a three-degree-of-freedom translational parallel kinematic machine (PKM), as an illustrative example.
