description: Il Programma PETROS, scritto da J. Kewisch e K. Steffen a DESY (1), per macchine a elettroni e positroni, modificato da G. Guisrard e Y. Marti al CERN (2, 3) (versione PETROC), è stato implementato sul VAX di Frascati. Il programma può eseguire i seguenti calcoli: - ottica lineare della macchina; - emittanza del fascio, lunghezza del pacchetto, dispersione in energia e vita media quantistica; - calcolo dell'orbita chiusa in presenza di errori gi posizione e di campo (...) elementi magnetici della macchina. Gli errori possono essere specificati dall'utente o scelti a caso secondo uma distribuzione gaussiana. - simulazione di correzione dell'orbita chiusa e calcolo delle corrispondenti correzioni includendo errori casuali di posizionamento dei rivelatori di campo dei correttori. Due modi di lavoro sono possibili: 1) Piani trasversali non accoppiati (matrici di trasporto 3x3 per i due piani); 2) piani trasversali accoppiati rappresentati del vettore (x, x', z, z', 𝞓p, p') (matrice di trasporto 5x5) (2,4). Nella versione attuale del programma il primo modo (1) non è in uso. In questo memorandum si descrivono le istruzioni per l'uso del programma sul VAX, sottolineando le variazioni apportate alla versione ricevuta dal CERN, descritta da Guisnard e Marti sul lavoro "PETROC Users' Guide"(2). Per una visione completa delle caratteristiche e delle possibilità di PETROC la lettura di tale articolo è quindi necessaria.

description: We present and analyze large-scale simulation results of a hybrid quantum-classical variational method to calculate the ground state energy of the anti-ferromagnetic Heisenberg model. Using a massively parallel universal quantum computer simulator, we observe that a low-depth-circuit ansatz advantageously exploits the efficiently preparable Néel initial state, avoids potential barren plateaus, and works for both one- and two-dimensional lattices. The analysis reflects the decisive ingredients required for a simulation by comparing different ansätze, initial parameters, and gradient-based versus gradient-free optimizers. Extrapolation to the thermodynamic limit accurately yields the analytical value for the ground state energy, given by the Bethe ansatz. We predict that a fully functional quantum computer with 100 qubits can calculate the ground state energy with a relatively small error.

description: We investigate tomography of 21-cm brightness temperature fluctuations during the Dark Ages as a probe for constraining primordial non-Gaussianity. We expand the 21- cm brightness temperature up to cubic order in perturbation theory and improve previous models of the signal by including the effect of the free electron fraction. Using modified standard perturbation theory methods that include baryonic pressure effects we derive an improved secondary bispectrum and for the first time derive the secondary trispectrum of 21-cm brightness temperature fluctuations. We then forecast the amount of information available from the Dark Ages to constrain primordial non-Gaussianity, including the imprints of massive particle exchange during inflation and we determine how much signal is lost due to secondary non-Gaussianity. We find that although secondary non-Gaussianity swamps the primordial signal, primordial non-Gaussianity can still be extracted with signal-to-noise ratios that surpass current and future CMB experiments by several orders of magnitude, depending on the experimental setup. Furthermore, we conclude that for the bi- and trispectra of massive particle exchange marginalizing over other primordial shapes affects signal-to-noise ratios more severely than secondary shapes. Baryonic pressure effects turn out to have a negligible impact on our forecasts, even at scales close to the Jeans scale. The results of this work reinforce the prospects of 21-cm brightness temperature fluctuations from the Dark Ages as the ultimate probe for primordial non-Gaussianity.

description: While a lot of research in explainable AI focuses on producing effective explanations, less work is devoted to the question of how people understand and interpret the explanation. In this work, we focus on this question through a study of saliency-based explanations over textual data. Feature-attribution explanations of text models aim to communicate which parts of the input text were more influential than others towards the model decision. Many current explanation methods, such as gradient-based or Shapley value-based methods, provide measures of importance which are well-understood mathematically. But how does a person receiving the explanation (the explainee) comprehend it? And does their understanding match what the explanation attempted to communicate? We empirically investigate the effect of various factors of the input, the feature-attribution explanation, and visualization procedure, on laypeople's interpretation of the explanation. We query crowdworkers for their interpretation on tasks in English and German, and fit a GAMM model to their responses considering the factors of interest. We find that people often mis-interpret the explanations: superficial and unrelated factors, such as word length, influence the explainees' importance assignment despite the explanation communicating importance directly. We then show that some of this distortion can be attenuated: we propose a method to adjust saliencies based on model estimates of over- and under-perception, and explore bar charts as an alternative to heatmap saliency visualization. We find that both approaches can attenuate the distorting effect of specific factors, leading to better-calibrated understanding of the explanation.

description: Per una prima valutazione dei parametri di un anello per luce di sincrotrone di energia tra 1.5 e 2.5 Gev è stata esaminata la soluzione a doppietti acromatici adottata per il progetto europeo (ESRP). In attesa di una più precisa definizione delle esigenze sperimentali, in una riunione con R. Rosei ed L. Fonda dell'Università di Trieste sono stati fissati, come base di partenza per il progetto di macchina, i seguenti requisiti: - circa 10 sezioni dritte per wigglers ed ondulatori con dispersione nulla, - circa 10 uscite di luce da magneti curvanti, - 0.5 ÷ 1.0 Kev in prima armonica dagli ondulatori, - 35 Kev da wigglers o wavelength shifters. Non sono emerse, almeno al momento, limitazioni esplicite sulla brillanza della sorgente e sulla struttura temporale dei fasci. Corrente accumulata dell'ordine di 100 mA con emittanza dell'ordi ne di 2÷3x10⁻⁸ m.rad sono stati ritenuti accettabili.

description: Nel Memorandum G-54 (M. Preger - "Condizioni per la correlazione energia-posizione in una sezione dispersiva di un anello di accumulazione") è dimostrato che non è possibile realizzare sulla macchina europea per luce di sincrotrone (ESRF) una inserzione nella quale le dimensioni di betatrone (cioè quelle di un fascio monocromatico di particelle) siano sensibilmente minori di quelle di sincrotrone (date dal prodotto della funzione di dispersione m per lo spread in energia del fascio di elettroni), in modo da poter selezionare l'energia degli elettroni con un fascio laser di sezione uguale (o addirittura minore) alle dimensioni di betatrone del fascio di elettroni, senza perturbare le funzioni ottiche all'interno dei magneti curvanti della macchina, che determinano l'emittanza dell'anello. Ciò è invece possibile quando nell'inserzione vengono ad essere compresi i magneti curvanti: viene qui presentata una soluzione nella quale l'inserzione è compresa tra i centri di due sezioni dispersive dell'ottica ESRP-27/3 (M. Preger - "A flexible lattice for ESRP - Status Report" - ESRP-IRM-7/83) contigue ad una sezione dritta lunga usata per la macchina normale per l'instal lazione di un ondulatore. In questa soluzione non viene modificata la struttura meccanica della macchina (non cambiano cioè le lunghezze degli elementi magnetici): cambiano le correnti dei quadrupoli dell'inserzione (simmetrica rispetto al centro della sezione dritta dell'ondulatore) e le polarità di quelli della sezione dispersiva. Le funzioni ottiche e le caratteristiche degli elementi magnetici dell'inserzione sono riportate nella Tabella 1. Per confronto, nella Tabella 2 sono dati i parametri corrispondenti per la macchina imperturbata. Nelle Figure 1 e 2 tali funzioni sono invece rappresentate graficamente. Non è stato considerato l'effetto dell'inserzione sulle caratteristiche non lineari della macchina (cromatismo e correzioni sestupolari). Gli effetti negativi dell'inserzione ad alta risoluzione sull'ottica dell'anello sono essenzialmente l'aumento dell'emittanza e dei valori massimi della funzione di betatrone radiale: la soluzione proposta rappresenta un compromesso tra le esigenze di risoluzione per il fascio di γ monocromatici e quelle di funzionamento come sorgente di luce di sincrotrone.

description: The tactile sensing capabilities of human hands are essential in performing daily activities. Simultaneously perceiving normal and shear forces via the mechanoreceptors integrated into the hands enables humans to achieve daily tasks like grasping delicate objects. In this paper, we design and fabricate a novel biomimetic tactile sensor with skin-like heterogeneity that perceives normal and shear contact forces simultaneously. It mimics the multilayers of mechanoreceptors by combining an extrinsic layer (piezoresistive sensors) and an intrinsic layer (a Hall sensor) so that it can perform estimation of contact force directions, locations, and joint-level torque. By integrating our sensors, a robotic gripper can obtain contact force feedback at fingertips; accordingly, robots can perform challenging tasks, such as tweezers usage, and egg grasping. This insightful sensor design can be customized and applied in different areas of robots and provide them with heterogeneous force sensing, potentially supporting robotics in acquiring skin-like tactile feedback.

description: Coarse-graining (CG) of molecular simulations simplifies the particle representation by grouping selected atoms into pseudo-beads and drastically accelerates simulation. However, such CG procedure induces information losses, which makes accurate backmapping, i.e., restoring fine-grained (FG) coordinates from CG coordinates, a long-standing challenge. Inspired by the recent progress in generative models and equivariant networks, we propose a novel model that rigorously embeds the vital probabilistic nature and geometric consistency requirements of the backmapping transformation. Our model encodes the FG uncertainties into an invariant latent space and decodes them back to FG geometries via equivariant convolutions. To standardize the evaluation of this domain, we provide three comprehensive benchmarks based on molecular dynamics trajectories. Experiments show that our approach always recovers more realistic structures and outperforms existing data-driven methods with a significant margin.

description: Bayesian approaches developed to solve the optimal design of sequential experiments are mathematically elegant but computationally challenging. Recently, techniques using amortization have been proposed to make these Bayesian approaches practical, by training a parameterized policy that proposes designs efficiently at deployment time. However, these methods may not sufficiently explore the design space, require access to a differentiable probabilistic model and can only optimize over continuous design spaces. Here, we address these limitations by showing that the problem of optimizing policies can be reduced to solving a Markov decision process (MDP). We solve the equivalent MDP with modern deep reinforcement learning techniques. Our experiments show that our approach is also computationally efficient at deployment time and exhibits state-of-the-art performance on both continuous and discrete design spaces, even when the probabilistic model is a black box.

description: The key achievement of 5G NORMA WP3 is the design of a conceptually novel, adaptive, and future-proof 5G mobile network architecture allowing to adapt the use of the mobile network (radio access, core, and transport) resources to the service requirements, the variations of the traffic demands over time and location, and the network topology (including the available front-/ back-haul capacity). The functional design is characterised by unprecedented levels of customisability, enabling stringent performance and security. This is achieved by specifying the two innovative functionality groups “multi-service and context-aware adaptation of network functions” and “mobile network multi-tenancy”. The technical enablers for these functionalities, “adaptive (de)composition and allocation of mobile network functions”, “software-defined mobile network control”, as well as “joint optimization of mobile access and core network functions”, are integrated into the 5G NORMA architecture design. Network functions from both the radio access and the core network domain have been decomposed and adaptively allocated to antenna site, edge cloud, or central cloud locations. This deliverable further presents the assessment and verification of the architecture based on realistic evaluation cases from the London study area defined in WP2. The security analysis in radio and core network domain has fuelled novel security concepts specifically addressing the challenges of multi-tenant and multi-service mobile networks with decomposed network functions. Finally, the deliverable describes an incremental migration path from 4G to 5G NORMA networks, focusing on functional and infrastructure evolution and allowing for co-existence of legacy technology components, particularly 4G (LTE-A and evolved packet core, EPC), and novel 5G NORMA building blocks.

To this aim, we exploit the recent development of quantum fluctuating hydrodynamics. Our findings for the entanglement Hamiltonian are based on the effective field theory description of the domain wall melting and are expected to exactly describe the Euler scaling limit of the lattice gas. However, such field theoretical results can be recovered from high-precision numerical lattice calculations only when summing appropriately over all the hoppings up to distant sites.

description: We study a simple model of a diffusing particle (the prey) that on encounter with one of a swarm of diffusing predators can either perish or be reset to its original position at the origin. We show that the survival probability of the prey up to time $t$ decays algebraically as $\sim t^{-θ(p, γ)}$ where the exponent $θ$ depends continuously on two parameters of the model, with $p$ denoting the probability that a prey survives upon encounter with a predator and $γ= D_A/(D_A+D_B)$ where $D_A$ and $D_B$ are the diffusion constants of the prey and the predator respectively. We also compute exactly the probability distribution $P(N|t_c)$ of the total number of encounters till the capture time $t_c$ and show that it exhibits an anomalous large deviation form $P(N|t_c)\sim t_c^{- Φ\left(\frac{N}{\ln t_c}=z\right)}$ for large $t_c$. The rate function $Φ(z)$ is computed explicitly. Numerical simulations are in excellent agreement with our analytical results.

description: The gluon radius of the proton is expected to increase at small gluon momentum fractions $x$, an effect which has hitherto not been considered in the dipole model framework. We investigate the energy dependence of exclusive $J/ψ$, $ϕ$, and $ρ$ production by introducing three models for $x$ dependence of the gluon thickness function. We allow the transverse width of the proton to increase as $x$ decreases, using novel parametrisations in the spherical proton and the hotspot model. We compare these with a model where the number of hotspots increases as $x$ decreases and confront the models with HERA data. The models exhibit clear differences in the slope of the $t$-spectra and in the cross section ratios between coherent and incoherent events. Comparisons to $t$-slopes and $W_{γp}$ measurements show a preference for models where the proton's size increases as $x$ decreases.

Community Sponsorship in Europe: Taking Stock, Policy Transfer and What the Future Might Hold
Creators: name: Tan, Nikolas Feith
Publisher: name: CEPS
Year: 2021

description: This article explores the recent emergence of community sponsorship of refugees in Europe, an approach which shares responsibility between civil society and the state for the admission and/or integration of refugees. Originally a Canadian model developed to support the resettlement of Indochinese refugees, the model has gained momentum in Europe, with a number of states piloting or establishing community sponsorship schemes. This proliferation, while generally seen as positive for international protection of refugees, has led to conceptual confusion and a significant range of approaches under the “umbrella” concept of community sponsorship. As a result, community sponsorship today may be understood both as a form of resettlement and a complementary pathway to protection. While interest and momentum around community sponsorship is high, little work currently exists mapping and analysing how jurisdictions adopt the community sponsorship model. With reference to existing work on policy transfer, this contribution takes stock of community sponsorship models in Europe; analyses how community sponsorship may become a viable policy option in European states as a form of transnational policy transfer; and sets out a number of challenges for the future development of community sponsorship in Europe.

description: There is an increasing interest in the amorphous states of metal-organic frameworks (MOFs) and porous coordination polymers, which can be produced by pressure-induced amorphization, temperature-induced amorphization, melt-quenching, ball-milling, irradiation, etc. They can exhibit useful physical and chemical properties, distinct from those achievable in the crystalline states, along with greater ease of processing, and intrinsic advantages over crystals and powders, such as high transparency and mechanical robustness. However, these amorphous states are particularly challenging to characterize, and the determination of their framework structure at the microscopic scale is difficult, with only indirect structural information available from diffraction experiments. In this Perspective, we review and compare the existing methodologies available for the determination of microscopic models of amorphous MOFs, based on both experimental data and simulation methods. In particular, we present the atomistic models that can be obtained using Reverse Monte Carlo (RMC) methods, Continuous Random Networks (CRN), classical and \emph{ab initio} molecular dynamics, reactive force fields, and simulated assembly/polymerization algorithms.

description: Stoquastic Hamiltonians play a role in the computational complexity of the local Hamiltonian problem as well as the study of classical simulability. In particular, stoquastic Hamiltonians can be straightforwardly simulated using Monte Carlo techniques. We address the question of whether two or more Hamiltonians may be made simultaneously stoquastic via a unitary transformation. This question has important implications for the complexity of simulating quantum annealing where quantum advantage is related to the stoquasticity of the Hamiltonians involved in the anneal. We find that for almost all problems no such unitary exists and show that the problem of determining the existence of such a unitary is equivalent to identifying if there is a solution to a system of polynomial (in)equalities in the matrix elements of the initial and transformed Hamiltonians. Solving such a system of equations is NP-hard. We highlight a geometric understanding of this problem in terms of a collection of generalized Bloch vectors.

description: In this paper we study the theoretical properties of the simultaneous multiscale change point estimator (SMUCE) proposed by Frick et al. (2014) in regression models with dependent error processes. Empirical studies show that in this case the change point estimate is inconsistent, but it is not known if alternatives suggested in the literature for correlated data are consistent. We propose a modification of SMUCE scaling the basic statistic by the long run variance of the error process, which is estimated by a difference-type variance estimator calculated from local means from different blocks. For this modification we prove model consistency for physical dependent error processes and illustrate the finite sample performance by means of a simulation study.

description: 325. Macmillan’s White-toothed Shrew Crocidura macmillani French: Crocidure de Macmillan / German: Macmillan-Weifszahnspitzmaus / Spanish: Musarana de Macmillan Other common names: Macmillan's Shrew Taxonomy. Crocidura luna macmillani Dollman, 1915, “ Kotelee, Walamo, Abyssinia [= Ethiopia].” The exact placement of C. macmillani is uncertain, but it has generally been placed in the endemic Ethiopian C. glass: group, although its distinct karyotype has called this into question. In recent genetic studies, the species was found to be included in the C. glassi group as the most basal lineage, and sister to C. yaldeni, although further studies are needed. Monotypic. Distribution. Koteke, the Middle Godjeb Valley, and Sheko Forest in SW Ethiopia. Descriptive notes. Head-body 73-87 mm, tail 52-57 mm, ear 9-9 mm, hindfoot 13-8-14-5 mm; weight 8-8 g. Macmillan’s White-toothed Shrew is small to mediumsized. Dorsal pelage is dark brownish gray to blackish gray, with gray-based, blacktipped individual hairs; ventral pelage is dark gray, with uniformly gray to dark gray hairs. Feet are dark gray dorsally. Tail is relatively long (c.70% of head-body length), covered in long bristle hairs, and is bicolored, being blackish gray dorsally and gray ventrally. Skull is narrow; braincase is inflated, as in other montane Ethiopian endemic Crocidura. There are three unicuspids. Chromosomal complement is 2n = 28, FN = 56. Habitat. Ethiopian montane tropical forest, and humid 7Terminalia-Combretum (both Combretaceae) woodland savanna with high grasses. Elevational range is 1220-1930 m. Food and Feeding. No information. Breeding. No information. Activity patterns. Macmillan’s White-toothed Shrews are terrestrial. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Near Threatened on The IUCN Red List. Macmillan’s White-toothed Shrew was only known from the holotype until 2001 when three more specimens were obtained. The species has a restricted distribution and may be primarily threatened by deforestation of its montane forest habitat. Bibliography. Bannikova et al.

description: Due to their chemical and structural diversity, nanoporous materials can be used in a wide variety of applications, including fluid separation, gas storage, heterogeneous catalysis, drug delivery, etc. Given the large and rapidly increasing number of known nanoporous materials, and the even bigger number of hypothetical structures, computational screening is an efficient method to find the current best-performing materials and to guide the design of future materials. This review highlights the potential of high-throughput computational screenings in various applications. The achievements and the challenges associated to the screening of several material properties are discussed to give a broader perspective on the future of the field.
A Framework for Distributed Quantum Queries in the CONGEST Model

description: The Quantum CONGEST model is a variant of the CONGEST model, where messages consist of $O(\log(n))$ qubits. We give a general framework for implementing quantum query algorithms in Quantum CONGEST, using the concept of parallel-queries. We apply our framework for distributed quantum queries in two settings: when data is distributed over the network, and graph theoretical problems where the network defines the input. The first is slightly unusual in CONGEST but our results follow almost directly. The second is more traditional for the CONGEST model but here we require some classical CONGEST steps to get our results. In the setting with distributed data, we show how a network can schedule a meeting in one of $k$ dates using $\tilde{O}(\sqrt{kD}+D)$ rounds, with $D$ the network diameter. We also give an algorithm for element distinctness: if all nodes together hold a list of $k$ numbers, they can find a duplicate in $\tilde O(k^{2/3}D^{1/3}+D)$ rounds. We also generalize the protocol for the distributed Deutsch-Jozsa problem from the two-party setting considered in [arXiv:quant-ph/9802040] to general networks, giving a novel separation between exact classical and exact quantum protocols in CONGEST. When the input is the network structure itself, we almost directly recover the $O(\sqrt{nD})$ round diameter computation algorithm of Le Gall and Magniez [arXiv:1804.02917]. We also compute the radius in the same number of rounds, and give an $ε$-additive approximation of the average eccentricity in $\tilde{O}(D+D^{3/2}/ε)$ rounds. Finally, we give quantum speedups for the problems of cycle detection and girth computation. We detect whether a graph has a cycle of length at most $k$ in $O(k+(kn)^{1/2-1/Θ(k)})$ rounds. For girth computation we give an $\tilde{O}(g+(gn)^{1/2-1/Θ(g)})$ round algorithm for graphs with girth $g$, beating the known classical lower bound.

description: We write the curvature of spacetime in terms of the excitation probability of particle detectors ultra-rapidly coupled to a quantum field. More precisely, we provide an expansion for the excitation probability of a smeared UDW detector delta-coupled to a real scalar quantum field in a curved background. Using a short distance expansion for the Wightman function, we express the excitation probability of a detector as the transition probability in Minkowski spacetime plus correction terms written as a function of the curvature tensors and the detector size. Comparing the excitation probability in curved spacetimes with its flat analog, we are able to express the components of the Ricci and Riemann curvature tensors as a function of physically measurable excitation probabilities of different shaped detectors.

description: Il semantic web e la tecnologia dei Linked Open Data implicano un ripensamento dell’attività di catalogazione: musei, archivi e biblioteche sono incentivati a svolgere un ruolo attivo nella definizione del nuovo Web, soprattutto nella redazione di vocabolari e di ontologie di dominio che ne rappresentano la base semantica. In questo quadro di interesse multidisciplinare l’organologia lamenta l’assenza di standard di catalogazione consolidati, e la conseguente compresenza e incompatibilità di sistemi e tecnologie diversi. I Linked Open Data forniscono strumenti per l’armonizzazione di dati eterogenei, garantendo accessibilità a informazioni e risorse tramite strategie di interoperabilità e condivisione. Il progettodi maggior rilievo che implementa i Linked Open Data applicati al patrimonio organologico è MIMO: il presente lavoro ne esamina obiettivi e caratteristiche implementative, quali l'adozione di LIDO e del CIDOC-CRM come modelli per la strutturazione dei metadati. Il nuovo contesto tecnologico è messo a confronto con il modello catalografico elaborato dall'etnomusicologo Febo Guizzi. La tesi, ponendo particolare attenzione alla preservazione delle competenze di dominio, elabora una prima digitalizzazione della "Scheda Guizzi" e restituisce un’analisi dettagliata dei vocabolari relativi al dominio degli strumenti musicali, con attenzione particolare per la Classificazione Hornbostel-Sachs e i thesauri digitalizzati da MIMO con le tecnologie semantiche. Infine redige un corpus di linee-guida per successive implementazioni che, orientate alle tecnologie interoperabili del semantic Web, intendono confluire nell’elaborazione di un’ontologia specifica per il dominio degli strumenti musicali.
