description: With upcoming blockchain infrastructures, world-spanning Byzantine consensus is getting practical and necessary. In geographically distributed systems, the pace at which consensus is achieved is limited by the heterogenous latencies of connections between replicas. If deployed on a wide-area network, consensus-based systems benefit from weighted replication, an approach that utilizes extra replicas and assigns higher voting power to well connected replicas. This enables more choice in quorum formation and replicas can leverage proportionally smaller quorums to advance, thus decreasing consensus latency. However, the system needs a solution to autonomously adjust to its environment if network conditions change or faults occur. We present Adaptive Wide-Area REplication (AWARE), a mechanism which improves the geographical scalability of consensus with nodes being widely spread across the world. Essentially, AWARE is an automated and dynamic voting weight tuning and leader positioning scheme, which supports the emergence of fast quorums in the system. It employs a reliable self-monitoring process and provides a prediction model seeking to minimize the system's consensus latency. In experiments using several AWS EC2 regions, AWARE dynamically optimizes consensus latency by self-reliantly finding a fast weight configuration yielding latency gains observed by clients located across the globe.

description: Analyzing the dynamical state of nearby young massive star clusters is essential understanding star cluster formation and evolution during their earliest stages. In this work we analyze the stellar and gas kinematics of the young massive star cluster Westerlund 2 (Wd2) using data from the integral field unit MUSE and complement them with proper motions from the Gaia DR2. The mean gas radial velocity of $15.9\,{\rm km}\,{\rm s}^{-1}$ agrees with the assumption that Wd2 is the result of a cloud-cloud collision. The gas motions show the expansion of the HII region, driven by the radiation from the many OB stars in the cluster center. The velocity profile of the cluster member stars reveal an increasing velocity dispersion with decreasing stellar mass and that the low-mass stars show five distinct velocity groups. Based on their spatial correlation with the cluster's two clumps, we concluded that this is the imprint of the initial cloud collapse that formed Wd2. A thorough analysis of the dynamical state of Wd2, which determines a dynamical mass range of $M_{\rm dyn,Wd2} = (7.5 \pm 1.9)\cdot10^4 - (4.4 \pm 1.1)\cdot10^5\,{\rm M}_\odot$ and exceeds the photometric mass by at least a factor of two leads to the conclusion that Wd2 is not massive enough to remain gravitationally bound. Additionally we also identify 22 runaway candidates with peculiar velocities between 30 and $546\,{\rm km}\,{\rm s}^{-1}$.

description: The energy spectrum for an ultracold rotating Bose gas in a harmonic trap is calculated exactly for small systems, allowing the atoms to occupy several Landau levels. Two vortex-like states and two strongly correlated states (the Pfaffian and Laughlin) are considered in detail. In particular, their critical rotation frequencies and energy gaps are determined as a function of particle number, interaction strength, and the number of Landau levels occupied (up to three). For the vortex-like states, the Lowest Landau level (LLL) approximation is justified only if the interaction strength decreases with the number of particles; nevertheless, the constant of proportionality increases rapidly with the angular momentum per particle. For the strongly correlated states, however, the interaction strength can increase with particle number without violating the LLL condition. The results suggest that in large systems, the Pfaffian and Laughlin states might be stabilized at rotation frequencies below the centrifugal limit for sufficiently large interaction strengths, with energy gaps a significant fraction of the trap energy.

description: The vibrational properties of a high-quality realistic model of amorphous silicon are examined. The longitudinal and transverse dynamical structure factors are calculated, and fitted to a damped harmonic oscillator (DHO) function. The width $Γ$ of the best-fit DHO to the longitudinal dynamical structure factor scales approximately as $k^{2}$ for wavevectors $k\lesssim0.55\textrmÅ^{-1}$, which is above the Ioffe-Regel crossover frequency separating the propagating and diffusing regimes, occurring at $k=0.38\pm0.03\textrmÅ^{-1}$. Using the DHO function as a fitting function for the transverse dynamical structure factor (without theoretical justification), gives a dependence of $Γ\propto k^α$ with $α\sim2.5$ for wavevectors $k\lesssim0.7\textrmÅ^{-1}$. There was no evidence for $Γ\propto k^{4}$ behaviour for either polarization.

description: The Five-hundred-meter Aperture Spherical radio Telescope (FAST) has started the Commensal Radio Astronomy FasT Survey (CRAFTS). In this paper, we use the technical parameters of FAST derived from commissioning observations to simulate the completeness function for extragalactic HI survey of CRAFTS, HI galaxies from two kinds of mock catalogues are selected. One is generated by Monte-Carlo simulation based on the interpolated mass-velocity width function of the ALFALFA $100\%$ (a.k.a. $α$ .100) catalogue. The other is constructed by semi-analytical N-body simulation based on the $Λ$CDM model. Our results suggest that a two-pass extragalactic HI survey will be able to detect nearly $4.8\times10^{5}$ galaxies, from which the 'faint end' slope of the HI Mass Function (HIMF) can be recovered to $\mathrm{10^{7}\, M_{\odot}}$ and the 'knee mass' of the HIMF can be measured to a redshift of 0.1. Considering the radio frequency interference status and sensitivity limitation, CRAFTS will be efficient in detecting HI galaxies at redshifts below 0.1, which implies a tremendous potential in exploring the galaxy interactions in different environments and the spatial distribution of HI galaxies in the local universe.

description: Measurements of inclusive production of the Lambda, Xi- and Xi*(1530) baryons in two-photon collisions with the L3 detector at LEP are presented. The inclusive differential cross sections for Lambda and Xi- are measured as a function of the baryon transverse momentum, pt, and pseudo-rapidity, eta. The mean number of Lambda, Xi- and Xi*(1530) baryons per hadronic two-photon event is determined in the kinematic range 0.4 GeV < pt< 2.5 GeV, |eta| < 1.2. Overall agreement with the theoretical models and Monte Carlo predictions is observed. A search for inclusive production of the pentaquark theta+(1540) in two-photon collisions through the decay theta+ -> proton K0s is also presented. No evidence for production of this state is found.

Equus phlegon

description: In 1893, Prof. E. D. Cope* described from the Blanco beds of Texas a horse which he called Equus minutus. It will. however, be necessary to apply to this animal a new name. since the term minutus had already been employed to designate another, probably two other, species of Equus.
 An Equus minutus was indicated by Marcelles de Serres in the year 1838,†but I have not been able to determine whether or not this name was accompanied by a description. For our present purpose this knowledge is not important. We have the following facts: In 1833 P. C. Schmerling‡ ﬁgured and described, without naming, some teeth of a small horse, found in caverns of Belgium, In 1858 A, von Nordmann§ wrote as follows: " Fur die kleinen Pferdezähne. angezeigt von Schmer* ling aus den Lutticher Knochenhohlen, ist von Marcelles de Serres die Benennung E. minutus vorgeschlagen Worden." This application of the name to those ﬁgured teeth would of itself be sufficient to give the name validity. I have been unable to ﬁnd any mention of this Equus minutus in works more recent than Gervais' Zoologie et Paléontologie francais, 2 nd edition, 1859, Where it is made a synonym of Equus adamaticus. This itself is a synonym of E. caballus. Trouessartǁ credits to Dubois an Equus minutus, regarding it also as a synonym of E. caballus. and omitting reference to place of publication. Dr. T S. Palmer, of the U. S. Department of Agriculture, kindly informs me that Trouessart quotes the name and author from Roger's Verzeichniss, 1887, p. 46, in which place no additional information is vouchsafed. If Dubois has described as new an Equus minutus, it too antedates Cope's species of that name.
 For the latter I propose the name Equus phlegon.**

description: We analyze the fidelity of a quantum simulation and we show that it displays fractal fluctuations iff the simulated dynamics is chaotic. This analysis allows us to investigate a given simulated dynamics without any prior knowledge. In the case of integrable dynamics, the appearance of fidelity fractal fluctuations is a signal of a highly corrupted simulation. We conjecture that fidelity fractal fluctuations are a signature of the appearance of quantum chaos. Our analysis can be realized already by a few qubit quantum processor.

The effects due to irradiating particles (pions, protons, neutrons), to their flux, to the anisotropy of the threshold energy in silicon, to the impurity concentrations and resistivity of the starting material are investigated as time, fluence and temperature dependences of detector characteristics. The expected degradation of the electrical parameters of detectors in the complex hadron background fields at LHC & SLHC are predicted.

As an illustration, we apply this method to the Kardar-Parisi-Zhang equation in 1+1 dimensions and show that the effective growth exponent of the surface width can be stabilized at any desired value in the interval [0.25,0.33], for a significant length of time. The method is quite general and can be applied to a wide range of growth phenomena. A possible experimental realization is suggested.

description: With the increase of IoT devices and technologies coming into service, Malware has risen as a challenging threat with increased infection rates and levels of sophistication. Without strong security mechanisms, a huge amount of sensitive data is exposed to vulnerabilities, and therefore, easily abused by cybercriminals to perform several illegal activities. Thus, advanced network security mechanisms that are able of performing a real-time traffic analysis and mitigation of malicious traffic are required. To address this challenge, we are proposing a novel IoT malware traffic analysis approach using deep learning and visual representation for faster detection and classification of new malware (zero-day malware). The detection of malicious network traffic in the proposed approach works at the package level, significantly reducing the time of detection with promising results due to the deep learning technologies used. To evaluate our proposed method performance, a dataset is constructed which consists of 1000 pcap files of normal and malware traffic that are collected from different network traffic sources. The experimental results of Residual Neural Network (ResNet50) are very promising, providing a 94.50% accuracy rate for detection of malware traffic.

description: Many existing digital triage systems are questionnaire-based, guiding patients to appropriate care levels based on information (e.g., symptoms, medical history, and urgency) provided by the patients answering questionnaires. Such a system often uses a deterministic model with predefined rules to determine care levels. It faces challenges with incomplete triage interviews since it can only assist patients who finish the process. In this study, we explore the use of machine learning (ML) to predict outcomes of unfinished interviews, aiming to enhance patient care and service quality. Predicting triage outcomes from incomplete data is crucial for patient safety and healthcare efficiency. Our findings show that decision-tree models, particularly LGBMClassifier and CatBoostClassifier, achieve over 80\% accuracy in predicting outcomes from complete interviews while having a linear correlation between the prediction accuracy and interview completeness degree. For example, LGBMClassifier achieves 88,2\% prediction accuracy for interviews with 100\% completeness, 79,6\% accuracy for interviews with 80\% completeness, 58,9\% accuracy for 60\% completeness, and 45,7\% accuracy for 40\% completeness. The TabTransformer model demonstrated exceptional accuracy of over 80\% for all degrees of completeness but required extensive training time, indicating a need for more powerful computational resources. The study highlights the linear correlation between interview completeness and predictive power of the decision-tree models.

Indomethacin : Capillary gas chromatographic-electron capture detection analysis and pharmacokinetic studies in the fetal lamb
Creators: name: Krishna, Rajesh
Publisher: name: University of British Columbia
Year: 2009

description: Indomethacin is currently used in the treatment of patent ductus arteriosus, preterm labour, and for polyhydramnios. In order to investigate its clearance and disposition in the chronically instrumented ovine fetus, a sensitive assay was required. The developed GC-ECD method involves the extraction of indomethacin and a-methyl indomethacin, the internal standard, from acidified plasma, urine, amniotic and tracheal fluids using a simple one-step liquid-liquid extraction procedure with ethyl acetate. The organic extract is evaporated and the residue derivatised with N-methyl-N-(tert-butyldimethylsilyl)-trifluoroacetamide (MTBSTFA). The derivatised samples were reconstituted with toluene and aliquots of 2 jxL injected into the GC. Calibration curves were linear over the working range of 1-32 ng of indomethacin/mL with a coefficient of determination (r ) > 0.99, following extraction of 0.1 mL of plasma, and 0.1-1.0 mL of urine, amniotic and tracheal fluids. Mean recoveries from plasma and urine were 96.99 ± 9.25 % and 94.74 ± 6.75 %, respectively. The limit of quantitation is 1 ng/mL (< 10% C.V., S/N > 10).Inter- and intra-day variabilities at each concentration point were < 11 % for concentrations between 2-32 ng/mL and < 20 % at the LOQ of 1 ng/mL. Ill The mean steady state fetal femoral arterial concentration of indomethacin was 181.67 ± 45.05 ng/mL in the high dose group (n=5), and 41.29 ± 3.14 ng/mL in the low dose group (n=2). The arterio-venous concentration difference for indomethacin at apparent steady state was minimal but statistically significant, suggesting a low placental permeability to indomethacin in sheep. The fetal total body clearance was estimated to be 44.55 + 11.14 mL/min (n=7). The placental clearance of indomethacin, as determined by the Fick principle, was calculated to be 8.85 ± 0.81 mL/min/kg. The renal clearance was estimated to be 0.015 + 0.009 mL/min (n=5). Indomethacin appeared in very low concentrations in amniotic fluid and fetal urine in high dose group fetuses. It was not observed to accumulate in tracheal fluid. The drug appeared to induce lactic acidosis and a reduction in fetal urinary output in some fetuses of the high dose group.

description: Chess game position analysis is important in improving ones game. It requires entry of moves into a chess engine which is, cumbersome and error prone. We present ARChessAnalyzer, a complete pipeline from live image capture of a physical chess game, to board and piece recognition, to move analysis and finally to Augmented Reality (AR) overlay of the chess diagram position and move on the physical board. ARChessAnalyzer is like a scene analyzer - it uses an ensemble of traditional image and vision techniques to segment the scene (ie the chess game) and uses Convolution Neural Networks (CNNs) to predict the segmented pieces and combine it together to analyze the game. This paper advances the state of the art in the first of its kind end to end integration of robust detection and segmentation of the board, chess piece detection using the fine-tuned AlexNet CNN and chess engine analyzer in a handheld device app. The accuracy of the entire chess position prediction pipeline is 93.45\% and takes 3-4.5sec from live capture to AR overlay. We also validated our hypothesis that ARChessAnalyzer, is faster at analysis than manual entry for all board positions for valid outcomes. Our hope is that the instantaneous feedback this app provides will help chess learners worldwide at all levels improve their game.

description: In this work, the current-induced inertial effects on skyrmions hosted in ferromagnetic systems are studied. {When the dynamics is considered beyond the particle-like description, magnetic skyrmions can deform due to a self-induced field. We perform Monte Carlo simulations to characterize the deformation of the skyrmion during its movement}. In the low-velocity regime, the deformation in the skyrmion shape is quantified by an effective inertial mass, which is related to the dissipative force. When skyrmions move faster, the large self-induced deformation triggers topological transitions. The transition is characterized by the proliferation of skyrmions and different total topological charge, which are obtained in terms of the skyrmion velocity. Our findings provide an alternative way to describe the skyrmion dynamics that take into account the deformations of its structure. Furthermore, the motion-induced topological phase transition brings the possibility to control the number of ferromagnetic skyrmions by velocity effects.

description: Unambiguous isospin violation in the strong interaction sector is a key issue in low energy hadronic physics, both experimentally and theoretically. Bernstein has employed the Fermi-Watson theorem to demonstrate that pion photoproduction is a process where isospin violation in the pi N system can be revealed, an approach we review here. Here we propose a general operator approach to the phenomenon in pion photoproduction, thereby providing an analogue for the framework that was proposed for pi N scattering by Kaufmann and Gibbs. The resulting set of amplitudes could form the basis for determining the multipole amplitudes for photoproduction. Thus, the so resulting phase shift determination from photoproduction can then be used via the Fermi-Watson theorem to resolve discrepancies in pi N phase shift analyses. We point out that casting effective Lagrangian results in terms of our framework would be beneficial. The upcoming polarization experiments are an ideal setting to test our approach, and also to constrain better the isotensor currents which strictly are not forbidden.

description: The disposition of this case above detailed, which disposition I believe to be uncontestable, on the assumption that two distinct genera are included in the lot of teeth described by Leidy, leaves those teeth represented by ﬁgures 21 -34 without speciﬁc name. It is possible that they are covered by some of the speciﬁc names which have been included under Prof. Cope`s genus Laelaps, but apparently they are not. Hence, I believe that I am justiﬁed in giving them a provisional speciﬁc title.
 The name Laelaps, having been employed in 1835 for a genus of Arachnida. is not available iıı the sense given it by Prof. Cope. Hence, Prof. Marsh‡properly substituted for it, in 1877, the name Dryptosaurus.
 To this genus then the teeth represented by ﬁgures 21 -34 of Dr. Leidy's plate IX seen to belong.

 †Trans. Amer. Philos., Soc., XVIII, p. 205.
 ‡Amer. jour. Sci.,[3], vol. XIV, p. 88.
They may be called Dryptosaurus kenabekides.*
 From the time of Leidy’s ﬁrst description there have been some reasons for suspecting that all the teeth described by him belonged to the same genus, indeed to the same animal. All those teeth were found “ in one place and possessed the same structural differences." Again, Prof. Cope in describing his Laelaps incrassatus; states that he found that the anterior denticulated carina of some of the anterior teeth was moved around the crown so that it was no longer opposite the hinder carina: and he says that a further transferrence would produce a tooth like those of Leidy's ﬁgures 35 -45, those with the U- shaped section. Furthermore, Cape says that he found a large tooth in immediate association with the jaw of his L. incrassatus, but separated from it, which had the posteriorly truncated section described by Leidy as typical; and Cope believed that this tooth belonged to the maxillary bone, near the position of the superior canine of a mammal.
 Nevertheless, in 1892 Prof. Cope: had the opportunity to study remains of L. incrassatus which furnished him nearly all parts of the skull; and he did not ﬁnd, either in the maxilla or in the dentary, teeth of the kind represented in Leidy’s ﬁgures 35-45. The teeth of the premaxilla were missing in his specimen and there remains the possibility that they are the ones which possess the U-shaped section. Meantime, it seems wiser to retain the genera as distinct, awaiting further discoveries.

description: We use angle-resolved photoemission spectroscopy (ARPES) to investigate the properties of the energy gap(s) in optimally doped (Bi,Pb)2(Sr,La)2CuO6+d (Bi2201). We find that the spectral gap has two components in the superconducting state: a superconducting gap and pseudogap. Significant differences in their momentum and temperature dependence suggest that they represent two separate energy scales. Spectra near the node reveal a sharp peak with a small gap below Tc that closes at Tc. Near the antinode, the spectra are broad with a large energy gap of ~40meV above and below Tc. The spectral shape and gap magnitude around the antinode are almost constant across Tc, which indicates that the pseudogap state coexists with the superconducting state below Tc, and it dominates the character of the spectra around the antinode. We speculate that the pseudogap state competes with the superconductivity by diminishing spectral weight in the antinodal regions, where the magnitude of the superconducting gap is largest.

description: The Second Arm SPectrometer (SASP) is a 130 ton 769 M e V / c QQClamshell magnetic spectrometer which pivots at the T2 location on the beam line 4B, and operates simultaneously in a coincidence mode with the existing M R S spectrometer. The new spectrometer was installed during the 1993-1994 and has undergone a series of commissioning runs as a single arm spectrometer. In this thesis two periods of commissioning, Aug. 13th to Sept. 23th and Nov. 18th to Dec.23th are described. The presented materiel is mainly concentrated on the first period which was devoted to the electronics, locating the SASP focal plane, and resolution studies. The second period is presented as a stage of development of different triggers and optics studies. The results obtained are described and analyzed. Although SASP was carefully designed to be operated over a wide range of angles, there is a problem with trying to operate at small angles. The extended field of the first Q l quadrupole is the major source of this problem. In the last Chapter the minimum possible angle for safe operation of SASP is determined. The calculations are based on the developed model of the extended Q l magnetic field.

description: Using the near-IR spectroscopy of the MOSFIRE Deep Evolution Field (MOSDEF) survey, we investigate the role of local environment in the gas-phase metallicity of galaxies. The local environment measurements are derived from accurate and uniformly calculated photometric redshifts with well-calibrated probability distributions. Based on rest-frame optical emission lines, [NII]$\lambda6584$ and H$α$, we measure gas-phase oxygen abundance of 167 galaxies at $1.37\leq z\leq1.7$ and 303 galaxies at $2.09\leq z\leq2.61$, located in diverse environments. We find that at $z\sim1.5$, the average metallicity of galaxies in overdensities with $M_*\sim10^{9.8}M_\odot, 10^{10.2}M_\odot$ and $10^{10.8}M_\odot$ is higher relative to their field counterparts by $0.094\pm0.051$, $0.068\pm0.028$ and $0.052\pm0.043$ dex, respectively. However, this metallicity enhancement does not exist at higher redshift, $z\sim2.3$, where, compared to the field galaxies, we find $0.056\pm0.043$, $0.056\pm0.028$ and $0.096\pm 0.034$ dex lower metallicity for galaxies in overdense environments with $M_*\sim10^{9.8}M_\odot, 10^{10.2}M_\odot$ and $10^{10.7}M_\odot$, respectively. Our results suggest that, at $1.37\leq z\leq2.61$, the variation of mass-metallicity relation with local environment is small ($<0.1$dex), and reverses at $z\sim2$. Our results support the hypothesis that, at the early stages of cluster formation, owing to efficient gas cooling, galaxies residing in overdensities host a higher fraction of pristine gas with prominent primordial gas accretion, which lowers their gas-phase metallicity compared to their coeval field galaxies. However, as the Universe evolves to lower redshifts ($z\lesssim2$), shock-heated gas in overdensities cannot cool down efficiently, and galaxies become metal-rich rapidly due to the suppression of pristine gas inflow and re-accretion of metal-enriched outflows in overdensities.

description: This paper details a number of indoor localization techniques developed for real-time monitoring of older adults. These were developed within the framework of the i-Light research project that was funded by the European Union. The project targeted the development and initial evaluation of a configurable and cost-effective cyber-physical system for monitoring the safety of older adults who are living in their own homes. Localization hardware consists of a number of custom-developed devices that replace existing luminaires. In addition to lighting capabilities, they measure the strength of a Bluetooth Low Energy signal emitted by a wearable device on the user. Readings are recorded in real time and sent to a software server for analysis. We present a comparative evaluation of the accuracy achieved by several server-side algorithms, including Kalman filtering, a look-back heuristic as well as a neural network-based approach. It is known that approaches based on measuring signal strength are sensitive to the placement of walls, construction materials used, the presence of doors as well as existing furniture. As such, we evaluate the proposed approaches in two separate locations having distinct building characteristics. We show that the proposed techniques improve the accuracy of localization. As the final step, we evaluate our results against comparable existing approaches.

description: Among the firm predictions of softly broken supersymmetry is the identity of gauge couplings and the corresponding Yukawa couplings between gauginos, sfermions and fermions. In the event that a SUSY-like spectrum of new particles is discovered at future colliders, a key follow-up will be to test these relations experimentally. In detailed studies it has been found that the SUSY-Yukawa couplings of the electroweak sector can be studied with great precision at the ILC, but a similar analysis for the Yukawa coupling of the SUSY-QCD sector is far more challenging. Here a first phenomenological study for determining this coupling is presented, using a method which combines information from LHC and ILC.

description: We establish the local Langlands conjecture for small rank general spin groups $GSpin_4$ and $GSpin_6$ as well as their inner forms. We construct appropriate $L$-packets and prove that these $L$-packets satisfy the properties expected of them to the extent that the corresponding local factors are available. We are also able to determine the exact sizes of the $L$-packets in many cases.

description: Contrary to the finite-dimensional case, the Moebius group admits interesting self-representations when infinite-dimensional. We construct and classify all these self-representations.
 The proofs are obtained in the equivalent setting of isometries of Lobachevsky spaces and use kernels of hyperbolic type, in analogy to the classical concepts of kernels of positive and negative type.

description: Mr. J. Z. Gilbert ll has described the skull of a species of Testudo from the Loup Fork beds of Kansas and identiﬁed it with Prof. Cope`s T. undata, described * from the Loup Fork deposits of New Mexico. Since nothing is known of the latter species except a few marginals and a costal bone, there is really no evidence that the ﬁne skull described by Gilbert belongs to T. undata. The probabilities are greater that it belongs to one of the species described by Prof. Copet from the Loup Fork beds of Kansas, Testudo orthopygia and T. cyclopygia. Ut T. orthopygia Prof. Cope possessed most of the skeleton including the skull. A comparison of Mr. Gilbert's ﬁgures and description with the description of Prof. Cope makes it pretty certain that the former is not identical with T, orthopygia. Of T. cyclopygia the skull is not known, and we have no means of comparing it with Mr. Gilbert's species. This being the case, it is better, I believe, to give the latter a distinct name. so that its literature may be kept separate until further discoveries demonstrate its relationship to other described forms.

description: In dense neutrino systems, such as found in the early Universe, or near a supernova core, neutrino flavor evolution is affected by coherent neutrino-neutrino scattering. It has been recently suggested that many-particle quantum entanglement effects may play an essential role in these systems, potentially invalidating the traditional description in terms of a set of single-particle evolution equations. We model the neutrino system by a system of interacting spins, following an earlier work which showed that such a spin system can in some cases be solved exactly. We extend this work by constructing an exact analytical solution to a more general spin system, including initial states with asymmetric spin distribution and, moreover, not necessarily aligned along the same axis. Our solution exhibits a rich set of behaviors, including coherent oscillations and dephasing and a transition from the classical to quantum regimes. We argue that the classical evolution of the spin system captures the entire coherent behavior of the neutrino system, while the quantum effects in the spin system capture some, but not all, of the neutrino incoherent evolution. By comparing the spin and neutrino systems, we find no evidence for the violation of the accepted one-body description, though the argument involves some subtleties not appreciated before. The analysis in this paper may apply to other two-state systems beyond the neutrino field.

description: We extend the physics-informed neural network (PINN) method to learn viscosity models of two non-Newtonian systems (polymer melts and suspensions of particles) using only velocity measurements. The PINN-inferred viscosity models agree with the empirical models for shear rates with large absolute values but deviate for shear rates near zero where the analytical models have an unphysical singularity. Once a viscosity model is learned, we use the PINN method to solve the momentum conservation equation for non-Newtonian fluid flow using only the boundary conditions.

description: Newton's rotating bucket pours cold water on the naive relationalist by vividly illustrating how certain rotational effects, particularly those due to non-zero angular momentum, can depend on more than just relations between material bodies. Because of such effects, rotation has played a central role in the absolute-relational debate and poses a particularly difficult challenge to the relationalist. In this paper, we provide a qualified response to this challenge that significantly weakens the absolutist position. We present a theory that, contrary to orthodoxy, can account for all rotational effects without introducing, as the absolutist does, a fixed standard of rotation. Instead, our theory posits a universal SO(3) charge that plays the role of angular momentum and couples to inter-particle relations via terms commonly seen in standard gauge theories such as electromagnetism and the Standard Model of particle physics. Our theory makes use of an enriched form of relationalism: it adds an SO(3) structure to the traditional relational description. Our construction is made possible by the modern tools of gauge theory, which reveal a simple relational law describing rotational effects. In this way, we can save the phenomena of Newtonian mechanics using conserved charges and relationalism. In a second paper, we will further explore the ontological and explanatory implications of the theory developed here.
