description: We report the measurements of de Haas-van Alphen (dHvA) oscillations in the noncentrosymmetric superconductor BiPd. Several pieces of a complex multi-sheet Fermi surface are identified, including a small pocket (frequency 40 T) which is three dimensional and anisotropic. From the temperature dependence of the amplitude of the oscillations, the cyclotron effective mass is ($0.18$ $\pm$ 0.1) $m_e$. Further analysis showed a non-trivial $π$-Berry phase is associated with the 40 T pocket, which strongly supports the presence of topological states in bulk BiPd and may result in topological superconductivity due to the proximity coupling to other bands.

description: We present a complete symmetry classification of the Sachdev-Ye-Kitaev (SYK) model with $\mathcal{N}=0$, $1$ and $2$ supersymmetry (SUSY) on the basis of the Altland-Zirnbauer scheme in random matrix theory (RMT). For $\mathcal{N}=0$ and $1$ we consider generic $q$-body interactions in the Hamiltonian and find RMT classes that were not present in earlier classifications of the same model with $q=4$. We numerically establish quantitative agreement between the distributions of the smallest energy levels in the $\mathcal{N}=1$ SYK model and RMT. Furthermore, we delineate the distinctive structure of the $\mathcal{N}=2$ SYK model and provide its complete symmetry classification based on RMT for all eigenspaces of the fermion number operator. We corroborate our classification by detailed numerical comparisons with RMT and thus establish the presence of quantum chaotic dynamics in the $\mathcal{N}=2$ SYK model. We also introduce a new SYK-like model without SUSY that exhibits hybrid properties of the $\mathcal{N}=1$ and $\mathcal{N}=2$ SYK models and uncover its rich structure both analytically and numerically.

description: We present a model for the scaling of mixing in weakly rotating stratified flows characterized by their Rossby, Froude and Reynolds numbers Ro, Fr, Re. It is based on quasi-equipartition between kinetic and potential modes, sub-dominant vertical velocity and lessening of the energy transfer to small scales as measured by the ratio rE of kinetic energy dissipation to its dimensional expression. We determine their domains of validity for a numerical study of the unforced Boussinesq equations mostly on grids of 10243 points, with Ro/Fr> 2.5 and with 1600< Re<1.9x104; the Prandtl number is one, initial conditions are either isotropic and at large scale for the velocity, and zero for the temperature θ, or in geostrophic balance. Three regimes in Fr are observed: dominant waves, eddy-wave interactions and strong turbulence. A wave-turbulence balance for the transfer time leads to rE growing linearly with Fr in the intermediate regime, with a saturation at ~0.3 or more, depending on initial conditions for larger Froude numbers. The Ellison scale is also found to scale linearly with Fr, and the flux Richardson number Rf transitions for roughly the same parameter values as well. Putting together the 3 relationships of the model allows for the prediction of mixing efficiency scaling as Fr-2~RB-1 in the low and intermediate regimes, whereas for higher Fr, it scales as RB-1/2, as already observed: as turbulence strengthens, rE~1, the velocity is isotropic and smaller buoyancy fluxes altogether correspond to a decoupling of velocity and temperature fluctuations, the latter becoming passive.

Thermal effects on coherence and excitation transfer

Subjects: subject: Quantum Physics (quant-ph)

description: To control and utilize quantum features in small scale for practical applications such as quantum transport, it is crucial to gain deep understanding of quantum characteristics of states such as coherence. Here by introducing a technique that simplifies solving the dynamical equation, we study the dynamics of coherence in a system of qubits interacting with each other through a common bath at non zero temperature. Our results demonstrate that depending on initial state, environment temperature affect coherence and excitation transfer in different ways. We show that when initial state is incoherent, as time goes on, coherence and probability of excitation transfer increase. But for coherent initial state, we find a critical value of temperature, below which system loses its coherence in time which diminishes the probability of excitation transfer. Hence in order to achieve higher value of coherence and also higher probability of excitation transfer, temperature of the bath should go beyond that critical value. Stationary coherence and probability of finding excited qubits in steady state, are discussed. We also elaborate on dependence of critical value of bath temperature on system size.

description: The purpose of this study was to understand the effects on oncology healthcare providers (HCPs), both personally and professionally, of watching digital stories made by adults with cancer (past and present), and what HCPs envisioned for the uses of digital stories. Seven healthcare professionals from various disciplines volunteered for this study. This research took place in a large urban center in Western Canada and was done in the tradition of philosophical hermeneutics. A 90-minute focus group was used for data collection, where participants watched eight digital stories (batched in four groups of two stories) that had been created by individuals with cancer (past or present). Data was analyzed using an interpretive qualitative methodology. Findings revealed that watching digital stories made by adults with cancer was emotionally compelling, provided context, incited deep introspection, and may offer a protective effect with respect to HCP burnout.

description: Precision measurements of frequency are critical to accurate timekeeping, and are fundamentally limited by quantum measurement uncertainties. While for time-independent quantum Hamiltonians, the uncertainty of any parameter scales at best as $1/T$, where $T$ is the duration of the experiment, recent theoretical works have predicted that explicitly time-dependent Hamiltonians can yield a $1/T^2$ scaling of the uncertainty for an oscillation frequency. This quantum acceleration in precision requires coherent control, which is generally adaptive. We experimentally realize this quantum improvement in frequency sensitivity with superconducting circuits, using a single transmon qubit. With optimal control pulses, the theoretically ideal frequency precision scaling is reached for times shorter than the decoherence time. This result demonstrates a fundamental quantum advantage for frequency estimation.

description: Quadratic algebras are generalizations of Lie algebras which include the symmetry algebras of 2nd order superintegrable systems in 2 dimensions as special cases. The superintegrable systems are exactly solvable physical systems in classical and quantum mechanics. Distinct superintegrable systems and their quadratic algebras can be related by geometric contractions, induced by Bôcher contractions of the conformal Lie algebra $\mathfrak{so}(4,\mathbb {C})$ to itself. In 2 dimensions there are two kinds of quadratic algebras, nondegenerate and degenerate. In the geometric case these correspond to 3 parameter and 1 parameter potentials, respectively. In a previous paper we classified all abstract parameter-free nondegenerate quadratic algebras in terms of canonical forms and determined which of these can be realized as quadratic algebras of 2D nondegenerate superintegrable systems on constant curvature spaces and Darboux spaces, and studied the relationship between Bôcher contractions of these systems and abstract contractions of the free quadratic algebras. Here we carry out an analogous study of abstract parameter-free degenerate quadratic algebras and their possible geometric realizations. We show that the only free degenerate quadratic algebras that can be constructed in phase space are those that arise from superintegrability. We classify all Bôcher contractions relating degenerate superintegrable systems and, separately, all abstract contractions relating free degenerate quadratic algebras. We point out the few exceptions where abstract contractions cannot be realized by the geometric Bôcher contractions.

description: In the context of superintelligent AI systems, the term "oracle" has two meanings. One refers to modular systems queried for domain-specific tasks. Another usage, referring to a class of systems which may be useful for addressing the value alignment and AI control problems, is a superintelligent AI system that only answers questions. The aim of this manuscript is to survey contemporary research problems related to oracles which align with long-term research goals of AI safety. We examine existing question answering systems and argue that their high degree of architectural heterogeneity makes them poor candidates for rigorous analysis as oracles. On the other hand, we identify computer algebra systems (CASs) as being primitive examples of domain-specific oracles for mathematics and argue that efforts to integrate computer algebra systems with theorem provers, systems which have largely been developed independent of one another, provide a concrete set of problems related to the notion of provable safety that has emerged in the AI safety community. We review approaches to interfacing CASs with theorem provers, describe well-defined architectural deficiencies that have been identified with CASs, and suggest possible lines of research and practical software projects for scientists interested in AI safety.

description: Cardiac magnetic resonance imaging improves on diagnosis of cardiovascular diseases by providing images at high spatiotemporal resolution. Manual evaluation of these time-series, however, is expensive and prone to biased and non-reproducible outcomes. In this paper, we present a method that addresses named limitations by integrating segmentation and disease classification into a fully automatic processing pipeline. We use an ensemble of UNet inspired architectures for segmentation of cardiac structures such as the left and right ventricular cavity (LVC, RVC) and the left ventricular myocardium (LVM) on each time instance of the cardiac cycle. For the classification task, information is extracted from the segmented time-series in form of comprehensive features handcrafted to reflect diagnostic clinical procedures. Based on these features we train an ensemble of heavily regularized multilayer perceptrons (MLP) and a random forest classifier to predict the pathologic target class. We evaluated our method on the ACDC dataset (4 pathology groups, 1 healthy group) and achieve dice scores of 0.945 (LVC), 0.908 (RVC) and 0.905 (LVM) in a cross-validation over the training set (100 cases) and 0.950 (LVC), 0.923 (RVC) and 0.911 (LVM) on the test set (50 cases). We report a classification accuracy of 94% on a training set cross-validation and 92% on the test set. Our results underpin the potential of machine learning methods for accurate, fast and reproducible segmentation and computer-assisted diagnosis (CAD).

description: In spherical surface wave tomography, one measures the integrals of a function defined on the sphere along great circle arcs. This forms a generalization of the Funk--Radon transform, which assigns to a function its integrals along full great circles. We show a singular value decomposition (SVD) for the surface wave tomography provided we have full data. Since the inversion problem is overdetermined, we consider some special cases in which we only know the integrals along certain arcs. For the case of great circle arcs with fixed opening angle, we also obtain an SVD that implies the injectivity, generalizing a previous result for half circles in [Groemer, On a spherical integral transform and sections of star bodies, Monatsh. Math., 126(2):117--124, 1998]. Furthermore, we derive a numerical algorithm based on the SVD and illustrate its merchantability by numerical tests.

description: Willie was enlisted and initially stationed in Northern Ireland before being sent to Normandy after the D-Day landings in June 1944. He was injured there by a shell that exploded beside a line of men he was standing in. Willie was standing in the line furthest from where the shell exploded and was the only one to survive; all the rest were killed. He never spoke of this, but he told his sister Helen in later life. It was a miracle he survived. Willie was sent back home to be patched up but was wounded a second time in April 1945. Willie was in the vicinity of the Rhine when he came under machine gun fire. Diving into a ditch, he cut his hand on a rusty wire, and his hand became badly infected. He returned home to Penicuik after the war, where he worked as a joiner. He was awarded four service medals.Chris and Helen, Willie's sisters, were very close. They joined the ATS and were attached to the Royal Artillery. They likely trained at Newbattle Abbey. Helen was demobbed on compassionate grounds. It appears that her mother found it too much to have all her children serving. Her mother had lost her own mother and sister to the Spanish Flu, and a brother had been a prisoner of war during WW1. Helen did not receive her war medal until 1970. There's no indication why this was delayed. Was it the case that women were suddenly awarded medals?All three siblings returned home from the war and lived together in Penicuik. Helen did the accounts for the family joinery business, and Chris worked as a cashier at one of the Penicuik paper mills. Helen taught Susan how to crochet as a child.None of the siblings married or had family. Susan believed that their mother's distress influenced their decision not to marry. Susan's father, Harry May, was the Wilsons' first cousin. Helen told the story of Willie's war service to Harry after Willie died. Susan wanted the Wilson siblings' story to be recorded as they have no living descendants, and otherwise, they would be forgotten.

description: Facial wrinkle is one of the most prominent biological changes that accompanying the natural aging process. However, there are some external factors contributing to premature wrinkles development, such as sun exposure and smoking. Clinical studies have shown that heavy smoking causes premature wrinkles development. However, there is no computerised system that can automatically assess the facial wrinkles on the whole face. This study investigates the effect of smoking on facial wrinkling using a social habit face dataset and an automated computerised computer vision algorithm. The wrinkles pattern represented in the intensity of 0-255 was first extracted using a modified Hybrid Hessian Filter. The face was divided into ten predefined regions, where the wrinkles in each region was extracted. Then the statistical analysis was performed to analyse which region is effected mainly by smoking. The result showed that the density of wrinkles for smokers in two regions around the mouth was significantly higher than the non-smokers, at p-value of 0.05. Other regions are inconclusive due to lack of large scale dataset. Finally, the wrinkle was visually compared between smoker and non-smoker faces by generating a generic 3D face model.

description: Protein kinase B (Akt1), which is a pivotal node in various cellular signaling pathways and up-regulated in many human tumors, has been regarded as a promising target to discover novel anticancer candidates. In this research, molecular modeling methods including molecular docking, three-dimensional quantitative structure–activity relationship (3 D-QSAR) and molecular dynamics (MD) simulation were applied on a series of Akt1 allosteric inhibitors to explore the structural requirements for their activities. Molecular docking study was performed to collect the binding mode of Akt1 with its inhibitors. Subsequently, comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) were used to generate 3 D-QSAR model. The Q2 and R2 values of the best CoMFA model were calculated as 0.612 and 0.992, while those for the best CoMSIA model were calculated as 0.595 and 0.991, which verified the accuracy of the models. Based on the contour maps, 15 novel Akt1 inhibitors were designed and all of them exhibited better predicted activities than the most active compound in the dataset. MD simulations were implemented to evaluate the stability of the complexes under physiological conditions and the results were congruent with molecular docking. Finally, binding free energy was calculated through molecular mechanics generalized born surface area (MM-GBSA) approach. The results were consistent with the bioactivities, which revealed that van der Waals and coulomb energy made the most contribution during the molecular binding process. In a word, our research provided a significant insight for further discovery of potent Akt1 allosteric inhibitors. Communicated by Ramaswamy H. Sarma

description: The availability, distribution, and quality of human resources for health (HRH) are crucial for achieving universal health coverage (UHC) in lower-to-middle income countries (LMICs), such as India. In India, there is one doctor for every 854 people, if we assume 80% availability of the 1,268,000 registered allopathic doctors and 565,000 registered alternative/complementary medicine (AYUSH) doctors. The lack of HRH severely impeded the healthcare expansion during the coronavirus disease 2019 (COVID-19) pandemic in India. This scoping review will address the contextual factors, constraints and enablers to the HRH shortage at national and subnational levels. The analysis in the review, based on close textual analysis of a broad range of documents, will offer a useful contribution to the understanding of healthcare workforce shortage in India.

description: Galaxy cluster velocity correlations and mass distributions are sensitive probes of cosmology and the growth of structure. Upcoming microwave surveys will enable extraction of velocities and temperatures from many individual clusters for the first time. We forecast constraints on peculiar velocities, electron temperatures, and optical depths of galaxy clusters obtainable with upcoming multi-frequency measurements of the kinematic, thermal, and relativistic Sunyaev-Zeldovich effects. The forecasted constraints are compared for different measurement configurations with frequency bands between 90 GHz and 1 THz, and for different survey strategies for the 6-meter CCAT-prime telescope. We study methods for improving cluster constraints by removing emission from dusty star forming galaxies, and by using X-ray temperature priors from eROSITA. Cluster constraints are forecast for several model cluster masses. A sensitivity optimization for seven frequency bands is presented for a CCAT-prime first light instrument and a next generation instrument that takes advantage of the large optical throughput of CCAT-prime. We find that CCAT-prime observations are expected to enable measurement and separation of the SZ effects to characterize the velocity, temperature, and optical depth of individual massive clusters ($\sim10^{15}\,M_\odot$). Submillimeter measurements are shown to play an important role in separating these components from dusty galaxy contamination. Using a modular instrument configuration with similar optical throughput for each detector array, we develop a rule of thumb for the number of detector arrays desired at each frequency to optimize extraction of these signals. Our results are relevant for a future "Stage IV" cosmic microwave background survey, which could enable galaxy cluster measurements over a larger range of masses and redshifts than will be accessible by other experiments.

Antioxidant activity was investigated by the ability of these compounds to scavenge the 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical cation (ABTS•+). Compounds 6a, 6b, 7, and 8b exhibited potent antitumour activities against all tested cell lines with [IC50] ≅5.5–18.1 µΜ), in addition to significantly high ABTS•+ scavenging activities. In vitro EGFR kinase assay for 6a, 6b, 7, and 8b as the most potent antitumour compounds showed that; compounds 6b, and 7 exhibited worthy EGFR inhibition activity with IC50 values of 0.56 and 1.6 µM, respectively, while compounds 6a and 8b showed good inhibition activity with IC50 values of 4.66 and 2.16 µM, respectively, compared with sorafenib reference drug (IC50 = 1.28 µM). Molecular modelling studies for compounds 6b, 7, and 8b were conducted to exhibit the binding mode towards EGFR kinase, which showed similar interaction with erlotinib.

description: It has recently been demonstrated that the large N limit of a model of fermions charged under the global/gauge symmetry group $O(N)^{q-1}$ agrees with the large $N$ limit of the SYK model. In these notes we investigate aspects of the dynamics of the $O(N)^{q-1}$ theories that differ from their SYK counterparts. We argue that the spectrum of fluctuations about the finite temperature saddle point in these theories has $(q-1)\frac{N^2}{2}$ new light modes in addition to the light Schwarzian mode that exists even in the SYK model, suggesting that the bulk dual description of theories differ significantly if they both exist. We also study the thermal partition function of a mass deformed version of the SYK model. At large mass we show that the effective entropy of this theory grows with energy like $E \ln E$ (i.e. faster than Hagedorn) up to energies of order $N^2$. The canonical partition function of the model displays a deconfinement or Hawking Page type phase transition at temperatures of order $1/\ln N$. We derive these results in the large mass limit but argue that they are qualitatively robust to small corrections in $J/m$.

description: We study long-range power-law correlated disorder on square and cubic lattices. In particular, we present high-precision results for the percolation thresholds and the fractal dimension of the largest clusters as function of the correlation strength. The correlations are generated using a discrete version of the Fourier filtering method. We consider two different metrics to set the length scales over which the correlations decay, showing that the percolation thresholds are highly sensitive to such system details. By contrast, we verify that the fractal dimension $d_{\rm f}$ is a universal quantity and unaffected by the choice of metric. We also show that for weak correlations, its value coincides with that for the uncorrelated system. In two dimensions we observe a clear increase of the fractal dimension with increasing correlation strength, approaching $d_{\rm f}\rightarrow 2$. The onset of this change does not seem to be determined by the extended Harris criterion.

description: We investigate the geometric properties of the convex hull over $n$ successive positions of a planar random walk, with a symmetric continuous jump distribution. We derive the large $n$ asymptotic behavior of the mean perimeter. In addition, we compute the mean area for the particular case of isotropic Gaussian jumps. While the leading terms of these asymptotics are universal, the subleading (correction) terms depend on finer details of the jump distribution and describe a "finite size effect" of discrete-time jump processes, allowing one to accurately compute the mean perimeter and the mean area even for small $n$, as verified by Monte Carlo simulations. This is particularly valuable for applications dealing with discrete-time jumps processes and ranging from the statistical analysis of single-particle tracking experiments in microbiology to home range estimations in ecology.

Πιο συγκεκριμένα, οι στόχοι της είναι, α. η ανάλυση του προβλήματος της χαρτογραφικής αποτύπωσης των στοών, β. η παραγωγή αναλογικού χάρτη τσέπης απεικόνισης των στοών της Αθήνας, γ. η δημιουργία χαρτογραφικής ιστοσελίδας των αθηναϊκών στοών. Τα αποτελέσματα στα οποία καταλήξαμε είναι: η ανάλυση της χαρτογραφικής απεικόνισης των στοών, ένας αναλογικός χάρτης τσέπης στον οποίο θα απεικονίζονται συνολικά οι στοές της Αθήνας, ξεχωριστοί χάρτες για τις κυριότερες στοές της πόλης και μια χαρτογραφικού κυρίως περιεχομένου, ιστοσελίδα, η οποία περιλαμβάνει ψηφιακό χάρτη απεικόνισης των στοών, τις χαρτογραφικές αποτυπώσεις των κυριότερων στοών της Αθήνας και όλες τις πληροφορίες που τις αφορούν. Αυτές οι πληροφορίες, αναφέρονται στην οδό (είσοδος-έξοδος στοάς), την τοποθεσία, τις υπηρεσίες και τα καταστήματα εντός των στοών και την προσβασιμότητα προς αυτές. Παρόλο που ο βασικός σκοπός της εργασίας είναι η απεικόνιση των στοών της Αθήνας, τόσο αναλογικά όσο και ψηφιακά, το βασικό αντικείμενο μελέτης είναι γενικότερα η έννοια της στοάς αλλά και κυρίως, ο τρόπος απεικόνισης της. Για το λόγο αυτό, η εργασία περιλαμβάνει επίσης την συλλογή πληροφοριών και τη συγκριτική μελέτη των αστικών ευρωπαϊκών και ελληνικών στοών. Έτσι, πραγματοποιείται μια ενδεικτική αναζήτηση πληροφοριών για τις στοές του Μιλάνο (Ιταλία), του Παρισιού (Γαλλία), του Λονδίνου (Αγγλία), του Βερολίνου (Γερμανία) και των Βρυξελλών (Βέλγιο). Ομοίως, η αναζήτηση για την Ελλάδα επικεντρώνεται στις πόλεις της Αθήνας, της Θεσσαλονίκης, της Πάτρας και του Βόλου. Τα αρχικά στοιχεία που συλλέγονται αποτελούν μια παρουσίαση των στοών των παραπάνω πόλεων και φέρουν απαντήσεις στα ερωτήματα που αφορούν την χρονολογία κατασκευής, τη σημερινή μορφή τους και τον λόγο για τον οποίο κατασκευάστηκαν. Στη συνέχεια, η μελέτη εστιάζει στο τρόπο της χαρτογραφικής απεικόνισης των στοών και αναλύει το πρόβλημα χαρτογράφησης τους. Η ανάλυση των συλλεχθέντων δεδομένων λύνει την κατανόηση της έννοιας της στοάς ενώ παράλληλα, η συλλογή όλων των δεδομένων των αθηναϊκών στοών αύξησε τις γνώσεις μας για τον σωστότερο τρόπο απεικόνισης τους. Λαμβάνοντας υπόψη αυτές τις πληροφορίες και χρησιμοποιώντας τα κατάλληλα εργαλεία, λογισμικά και δεδομένα, προέκυψε ο αναλογικός χάρτης τσέπης και μια χαρτογραφική ιστοσελίδα των στοών της Αθήνας. Λέξεις κλειδιά: στοά, χάρτης τσέπης, ιστοσελίδα, χαρτογραφική απεικόνιση.

Then sent to Libya - desert rats, served in Battle of Tobruk 1942, attacked by German tanks and artillery - Peter was the only survivor out of 6-8 men. Shrapnel wounds over all body, lost one of his eyes. Lots of shrapnel retained by his body for rest of his life. Prior to Tobruk, shipped to South Africa. Captured by Germans in Tobruk after injured - taken to Tobruk POW camp - treated for his injuries - given glass eye by Germans - kept alive. Then moved by Germans to Red Cross ship. Military hospital in Naples then to Northern Italy to Bergamo, another hospital. Still being cared for by Germans and Italians. Then moved to a POW camp in Carpi in Italy PG73 (ref number) and then sent back to England on Red Cross ship on 14 April 1943. Repatriated. On recovery, sent to anti-aircraft guns in London - doodlebugs, heavy bombing. Stayed in London.
Experimental consolidation and absolute measurement of the nat C(p,x)11 C nuclear activation cross section at 100 MeV for particle therapy physics

description: The natC(p,x)11C reaction has been discussed in detail in the past [EXFOR database, Otuka et al. (Nuclear Data Sheets 120:272–276, 2014)]. However, measured activation cross sections by independent experiments are up to 15% apart. The aim of this study is to investigate underlying reasons for these observed discrepancies between different experiments and to determine a new consensus reference cross section at 100 MeV. Therefore, the experimental methods described in the two recent publications [Horst et al. (Phys Med Biol https://doi.org/10.1088/1361-6560/ab4511 [Titel anhand dieser DOI in Citavi-Projekt übernehmen] , 2019) and Bäcker et al. (Nuclear Instrum Methods Phys Res B 454:50–55, 2019)] are compared in detail and all experimental parameters are investigated for their impact on the results. For this purpose, a series of new experiments is performed. With the results of the experiments a new reference cross section of (68±3) mb is derived at (97±3) MeV proton energy. This value combined with the reliably measured excitation function could provide accurate cross section values for the energy region of proton therapy. Because of the well-known gamma-ray spectrometer used and the well-defined beam characteristics of the treatment machine at the proton therapy center, the experimental uncertainties on the absolute cross section could be reduced to 3%. Additionally, this setup is compared to the in-beam measurement setup from the second study presented in the literature (Horst et al. 2019). Another independent validation of the measurements is performed with a PET scanner.

description: Next generation radio experiments such as LOFAR, HERA and SKA are expected to probe the Epoch of Reionization and claim a first direct detection of the cosmic 21cm signal within the next decade. Data volumes will be enormous and can thus potentially revolutionize our understanding of the early Universe and galaxy formation. However, numerical modelling of the Epoch of Reionization can be prohibitively expensive for Bayesian parameter inference and how to optimally extract information from incoming data is currently unclear. Emulation techniques for fast model evaluations have recently been proposed as a way to bypass costly simulations. We consider the use of artificial neural networks as a blind emulation technique. We study the impact of training duration and training set size on the quality of the network prediction and the resulting best fit values of a parameter search. A direct comparison is drawn between our emulation technique and an equivalent analysis using 21CMMC. We find good predictive capabilities of our network using training sets of as low as 100 model evaluations, which is within the capabilities of fully numerical radiative transfer codes.

Quantum non-Markovianity and localization

description: We study the behavior of non-Markovianity with respect to the localization of the initial environmental state. The "amount" of non-Markovianity is measured using divisibility and distinguishability as indicators, employing several schemes to construct the measures. The system used is a qubit coupled to an environment modeled by an Ising spin chain kicked by ultra-short pulses of a magnetic field. In the integrable regime, non-Markovianity and localization do not have a simple relation, but as the chaotic regime is approached, simple relations emerge, which we explore in detail. We also study the non-Markovianity measures in the space of the parameters of the spin coherent states and point out that the pattern that appears is robust under the choice of the interaction Hamiltonian but does not have a KAM-like phase-space structure.

description: Process-induced residual stresses significantly influence the mechanical properties of a formed component. A polymer pad is used as a flexible die in two-point incremental forming to induce compressive residual stresses in the component during the forming process. Experimental and numerical results illustrate the influence of compressive stress superposition on the component properties. It is shown that the active support, using a geometry-independent polyurethane die, causes beneficial compressive residual stresses on the tool side compared to the tensile residual stresses induced by the single-point incremental forming process without such a supporting die.
