description: If the top quark is a composite state made out of some constituents, its interaction with the gluon will be modified. We introduce the leading effective operators that contribute to the radius and anomalous magnetic moment of the top quark and study their effect on the cross section for top anti-top production at the Tevatron and the LHC. Current measurements of the cross sections set a stringent limit on the scale of compositeness. This limit is comparable to similar limits obtained for light quarks and those from electroweak precision measurements. It can be used to constrain the parameter space of some composite Higgs models.

description: A special class of non-minimal operators which are relevant for quantum field theory is introduced. The general form of the heat kernel coefficients of these operators on manifolds without boundary is described. New results are presented for the traces of the first two heat kernel coefficients for vector, Yang-Mills and perturbative gravity. It is argued that non-minimal operators can be used to define gauge-fixing independent actions and solve the conformal mode problem in quantum gravity.

Collective Anomaly Perception During Multi-Robot Patrol: Constrained Interactions Can Promote Accurate Consensus

description: An important real-world application of multi-robot systems is multi-robot patrolling (MRP), where robots must carry out the activity of going through an area at regular intervals. Motivations for MRP include the detection of anomalies that may represent security threats. While MRP algorithms show some maturity in development, a key potential advantage has been unexamined: the ability to exploit collective perception of detected anomalies to prioritize the location ordering of security checks. This is because noisy individual-level detection of an anomaly may be compensated for by group-level consensus formation regarding whether an anomaly is likely to be truly present. Here, we examine the performance of unmodified idleness-based patrolling algorithms when given the additional objective of reaching an environmental perception consensus via local pairwise communication and a quorum threshold. We find that generally, MRP algorithms that promote physical mixing of robots, as measured by a higher connectivity of their emergent communication network, reach consensus more quickly. However, when there is noise present in anomaly detection, a more moderate (constrained) level of connectivity is preferable because it reduces the spread of false positive detections, as measured by a group-level F-score. These findings can inform user choice of MRP algorithm and future algorithm development.

description: We define a new inflationary scenario in which inflation starts naturally after the Big Bang when the energy density drops below some critical value. As a model, we use recently proposed symmetron field whose effective potential depends on the energy density of the environment. At high densities, right after the Big Bang, the potential for the symmetron is trivial, and the field sits in equilibrium at the bottom of the potential. When the density drops below some critical value, the potential changes its shape into a symmetry breaking potential, and the field starts rolling down. This scenario does not require any special initial conditions for inflation to start. We also construct a concrete model with two fields, i.e. with symmetron as an inflaton and an additional scalar field which describes the matter content in the early universe. For the simplest coupling, the amplitude and shape of the power spectrum are the same as in the single field slow-roll inflation.

description: We show that under appropriate conditions the impact of a very short and intense laser pulse onto a plasma causes the expulsion of surface electrons with high energy in the direction opposite to the one of propagation of the pulse. This is due to the combined effects of the ponderomotive force and the huge longitudinal field arising from charge separation ("slingshot effect"). The effect should also be present with other states of matter, provided the pulse is sufficiently intense to locally cause complete ionization. An experimental test seems to be feasible and, if confirmed, would provide a new extraction and acceleration mechanism for electrons, alternative to traditional radio-frequency-based or Laser-Wake-Field ones.

description: The detailed analysis of phenomena and observation requirements for the Arctic region given in this report reveals the following conclusions: • The Arctic is a region very sensitive to environmental changes. There is a very close interrelation and delicate balance between the five thematic areas investigated(atmosphere, terrestrial, cryosphere, sea ice and ocean),especially in relation to solar energy and radiation budget and hydrological cycle. This has a great impact on physical, chemical and biological processes in the area. • Due to the hostile environment, there is a great lack of basic observations in the Arctic,that can support scientific understanding of key processes. Most of the existing data are collected via time limited research projects. This lack of process knowledge is reflected in big errors in forecasting models –operational as well as climate. • It is therefore crucial to establish a sustained Integrated Arctic Observing System,that in the short time frame can increase fundamental scientific understanding of the complex and sensitive Arctic environment and in a longer time frame can secure a robust basis for decision making to the benefit of the people living in the Arctic, the environment, the broader international society, and commercial activities. • It is foreseen that a future Arctic observation system will rely heavily on satellite observations supplemented by more traditional in-situ platforms. Especially the ocean will use several other platforms such as ships, profiling floats, gliders, moorings, AUVs etc. to monitor the interior of the Arctic Ocean. • In all countries around the Arctic, there are community based observing systems that represent a strong potential for further development. Existing activities shall form part of the natural basis for a future more intensive and integrated sustainable Arctic Observing System. • A stakeholder workshop was held in Brussel on 5 May, organised by EuroGOOS, where status and challenges regarding development of Arctic Observing Systems were discussed. In addition to technical and logistical challenges, there are also organisational barriers to building and operating a multidisciplinary observing system. These issues will be addressed in follow-up workshops.

description: We study the statistical properties of spectrum and eigenstates of the Google matrix of the citation network of Physical Review for the period 1893 - 2009. The main fraction of complex eigenvalues with largest modulus is determined numerically by different methods based on high precision computations with up to $p=16384$ binary digits that allows to resolve hard numerical problems for small eigenvalues. The nearly nilpotent matrix structure allows to obtain a semi-analytical computation of eigenvalues. We find that the spectrum is characterized by the fractal Weyl law with a fractal dimension $d_f \approx 1$. It is found that the majority of eigenvectors are located in a localized phase. The statistical distribution of articles in the PageRank-CheiRank plane is established providing a better understanding of information flows on the network. The concept of ImpactRank is proposed to determine an influence domain of a given article. We also discuss the properties of random matrix models of Perron-Frobenius operators.

description: We consider quantum-information division, which is characterized by a channel whose outputs have no correlation and are not completely randomized. We show that the quantum-information division is possible in a probabilistic manner by optimizing the average fidelity in the channel with $M$ outputs in both deterministic and probabilistic cases. Moreover, we show that the optimal fidelities drastically change depending on the condition imposed on the outputs (symmetric and asymmetric), which is quite in contrast to the case of imperfect cloning.

The course was designed with the purpose of showing in practice what means active learning in physics and how effective activities can be realized in practice. Two different type of teachers attended to the course, a small group, with physics or mathematics degree, for teacher qualification in secondary school of second grade (age 14-19) and a more numerous group for qualification in secondary school of first grade (age 11-14), usually with a different science degree such as biology, environmental sciences and so on. We compare this training in physics lab between the two groups and with other experiences we performed in previous years in pre-service education and updating courses for teachers in-service.

description: As part of the external project communication strategy, the IMI team compiled 4 external newsletters for a more general audience with little to no knowledge of the project. The newsletters were used to share project information and updates with the aim to cultivate continuous, bi-directional knowledge-transfer between the project and its different stakeholders. A content plan for newsletters was developed by IMI and drafts were written for release to external stakeholder audiences in coordination with the calendar of planned media releases during RP3. These newsletters focused on project information, achievements, updates and shared the progress made at each demosite, and were disseminated regularly to all stakeholders who signed up for project updates. Each issue contained information about an overarching aspect of the project (such as the need for a circular water economy and how Project Ô contributes to the United Nations Sustainable Development Goals), a focus on a demosite (Italy, Israel, Spain and Croatia) and the technologies implemented (ADV.ERT, SALTECH, MOBILE3TECH and PHOTO.CAT), latest news (including tours of demosites, project partners at conferences), upcoming events (such as the International School on Water Reuse, public engagement events, and stakeholder engagement events) useful visual content and other communication materials (access to project brochures, videos etc). Project partners were regularly invited to share their latest updates with the team for inclusion in the newsletters.

description: In the light of the COVID-19 restrictions on working and meeting conditions the INTAROS Stakeholder Task Team decided to concentrate stakeholder activities during the last two years of the project on:
 • Dialog meetings with relevant European Research Infrastructures
 • A survey among sensor and instrument manufacturers.
 • Meeting with representatives of national managing authorities.
 • Attending relevant virtual conferences, webinars and networking events wherever possible. Successful dialog meetings were performed with 12 European Research Infrastructures revealing a good insight in their Arctic engagement, strategies and priorities for in situ observation, data management, focus on best practices, technology development, cooperation and coordination among themselves, funding situation and willingness to engage in future Arctic Observing System.
 More than 100 sensor and instrument manufacturers were invited to respond to a web-based technology survey – disappointingly only 16 companies responded. The survey showed that there is a group of sensor and instrument manufacturers that have experience, capability and interest in participating in innovation of new technology in the harsh Arctic environment. The marine and maritime management authorities expressed great interest in gaining environmental data from the Arctic region. Especially time series and trends are of importance, but also data in support of reliable ecosystem modelling was highlighted.
 The INTAROS achievements have been broadly promoted by the consortium members at conferences, workshops, webinars etc. primarily via virtual technology whereby the personal contact and networking has been lost. Some relevant events have been postponed or cancelled, so the outreach activity has not been so high as in the early part of the project.
Dynamical friction in cuspy galaxies

description: In this paper we treat the problem of the dynamical friction decay of a massive object moving in an elliptical galaxy with a cuspidal inner distribution of the mass density. We present results obtained by both self-consistent, direct summation, N-body simulations, as well as by a new semi-analytical treatment of dynamical friction valid in such cuspy central regions of galaxies. A comparison of these results indicates that the proposed semi-analytical approximation is the only reliable in cuspy galactic central regions, where the standard Chandrasekhar's local approximation fails, and, also, gives estimates of decay times that are correct at 1% respect to those given by N-body simulations. The efficiency of dynamical friction in cuspy galaxies is found definitively higher than in core galaxies, especially on more radially elongated satellite orbits. As another relevant result, we find a proportionality of the dynamical friction decay time to the -0.67 power of the satellite mass, M, shallower than the standardly adopted 1/M dependence.

We generalize the notion of affine quandle, by using heap endomorphisms and metahomomorphisms, and identify the underlying Yang-Baxter algebra for solutions of the braid equation associated to a given quandle. We introduce the notion of the pre-Lie skew brace and identify certain affine quandles that give rise to pre-Lie skew braces. Generalisations of the braiding of a group, associated to set-theoretic solutions of the braid equation are also presented. These generalized structures encode part of the underlying Hopf algebra. We then introduce the quasi-triangular (quasi) Hopf algebras and universal R-matrices for rack and set-theoretic algebras. Generic set-theoretic solutions coming from heap endomorphisms are also identified.

description: Traditional control theory-based methods require tailored engineering for each system and constant fine-tuning. In power plant control, one often needs to obtain a precise representation of the system dynamics and carefully design the control scheme accordingly. Model-free Reinforcement learning (RL) has emerged as a promising solution for control tasks due to its ability to learn from trial-and-error interactions with the environment. It eliminates the need for explicitly modeling the environment's dynamics, which is potentially inaccurate. However, the direct imposition of state constraints in power plant control raises challenges for standard RL methods. To address this, we propose a chance-constrained RL algorithm based on Proximal Policy Optimization for supervisory control. Our method employs Lagrangian relaxation to convert the constrained optimization problem into an unconstrained objective, where trainable Lagrange multipliers enforce the state constraints. Our approach achieves the smallest distance of violation and violation rate in a load-follow maneuver for an advanced Nuclear Power Plant design.

description: The accurate determination of the position-dependent energy fluence rate of scattered light (which is proportional to the energy density) is crucial to the understanding of transport in anisotropically scattering and absorbing samples, such as biological tissue, seawater, atmospheric turbulent layers, and light-emitting diodes. While Monte Carlo simulations are precise, their long computation time is not desirable. Common analytical approximations to the radiative transfer equation (RTE) fail to predict light transport and could even give unphysical results. Therefore, we experimentally probe the position-dependent energy fluence rate of light inside scattering samples where the widely used P1 and P3 approximations to the RTE fail. The samples are three-dimensional (3D) aqueous suspensions of anisotropically scattering and both absorbing and non-absorbing spherical scatterers, namely, microspheres (r = 0.5 um) with and without absorbing dye. To probe the energy fluence rate, we detect the emission of quantum-dot reporter particles that are excited by the incident light and that are contained in a thin capillary. By scanning the capillary through the sample, we access the position dependence. We present a comprehensive discussion of experimental limitations and of both random and systematic errors. Our observations agree well with the Monte Carlo simulations and the P3 approximation of the RTE with a correction for forward scattering. In contrast, the P1 and the P3 approximations deviate increasingly from our observations, ultimately even predicting unphysical negative energies.

description: Synchronization is a universal phenomenon that is important both in fundamental studies and in technical applications. Here we investigate synchronization in the simplest quantum-mechanical scenario possible, i.e., a quantum-mechanical self-sustained oscillator coupled to an external harmonic drive. Using the power spectrum we analyze synchronization in terms of frequency entrainment and frequency locking in close analogy to the classical case. We show that there is a step-like crossover to a synchronized state as a function of the driving strength. In contrast to the classical case, there is a finite threshold value in driving. Quantum noise reduces the synchronized region and leads to a deviation from strict frequency locking.

description: Task 9.3 foresees the study of a novel charge readout scheme for very large liquid-argon time projection chambers named Vertical Drift. This technology avoids using wires to collect the signals of the electrons from charged-particle ionization, at the end of their drift path. Wire planes are instead replaced by stacks of perforated printed circuit boards integrated in charge readout planes of 3x3.3 m2 placed to cover the surface at the top of the detector. This active surface receives the electrons drifting thanks to a uniform electric field aligned along the vertical axis. The cryogenic ASIC amplifiers used to read the signals are integrated in this layout in front-end cards by hosted-in-cryostat penetrations ‘signal feedthrough chimneys” which make them accessible from outside during detector operation. The digitization electronics at warm are cabled to warm flanges closing the top part of the chimneys. This technology, which is foreseen to equip the second DUNE Far Detector module, underwent extensive large-scale tests at the CERN Neutrino Platform in 2021-2022. These tests successfully demonstrated its validity. This milestone reports about the work and developments performed on the chimneys.

description: Sliding friction is usually introduced in high school, but rarely through activities in laboratory. A qualitative introduction to friction is presented by proposing exploration of different kind of materials in order to suggest which aspects can be relevant and which interaction is involved. Different quantitative experiments are proposed for studying Leonardo's laws for friction. The learning path was tested with two high school classes during an instruction trip at department. Students were engaged in the inquiry-based introductory activity and seemed to realize with care the measurements. However, the analysis of their reports shows some learning difficulties.

description: We discussed in arXiv:1209.0772 that the laboratory frame distribution of the energy of a massless particle from a two-body decay at a hadron collider has a peak whose location is identical to the value of this daughter's (fixed) energy in the rest frame of the corresponding mother particle. For that result to hold we assumed that the mother is unpolarized and has a generic boost distribution in the laboratory frame. In this work we discuss how this observation can be applied for determination of masses of new particles, without requiring a full reconstruction of their decay chains or information about the rest of the event. We focus on a two-step cascade decay of a massive particle that has one invisible particle in the final state: C -> Bb -> Aab, where C, B and A are new particles of which A is invisible and a, b are visible particles. Combining the measurements of the peaks of energy distributions of a and b with that of the edge in their invariant mass distribution, we demonstrate that it is in principle possible to determine separately all three masses of the new particles, in particular, without using any measurement of missing transverse momentum. Furthermore, we show how the use of the peaks in an inclusive energy distribution is generically less affected by combinatorial issues as compared to other mass measurement strategies. For some simplified, yet interesting, scenarios we find that these combinatorial issues are absent altogether. As an example of this general strategy, we study SUSY models where gluino decays to an invisible lightest neutralino via an on-shell bottom squark. Taking into account the dominant backgrounds, we show how the mass of the bottom squark, the gluino and (for some class of spectra) that of the neutralino can be determined using this technique.

description: Hydrodynamic and magnetohydrodynamic convective attractors in three-dimensional rotating Rayleigh-Bénard convection are studied numerically by varying the Taylor and Rayleigh numbers as control parameters. First, an analysis of hydrodynamic attractors and their bifurcations is conducted, where routes to chaos via quasiperiodicity are identified. Second, the behaviour of the magnetohydrodynamic system is investigated by introducing a seed magnetic field and measuring its growth or decay as a function of the Taylor number, while keeping the Rayleigh number fixed. Analysis of the attractors shows that rotation has a significant impact on magnetic field generation in Rayleigh-Bénard convection, with the critical magnetic Prandtl number changing nonmonotonically with the rotation rate. It is argued that a nonhysteretic blowout bifurcation with on-off intermittency is responsible for the transitions to dynamo.

description: The reform of the upper secondary school in Italy has recently introduced physics in the curricula of professional schools, in realities where it was previously absent. Many teachers, often with a temporary position, are obliged to teaching physics in schools where the absence of the laboratory is added to the lack of interest of students who feel this matter as very far from their personal interests and from the preparation for the work which could expect from a professional school. We report a leaning path for introducing students to the measurement of simple physical quantities, which continued with the study of some properties of matter (volume, mass, density) and ending with some elements of thermodynamics. Educational materials designed in order to involve students in an active learning, actions performed for improving the quality of laboratory experience and difficulties encountered are presented. Finally, we compare the active engagement of these students with a similar experience performed in a very different vocational school.

description: Aperiodic tilings are non-periodic tilings defined by local rules. They are widely used to model quasicrystals, and a central question is to understand which of the non-periodic tilings are actually aperiodic. Among tilings, those by rhombi can be easily seen as approximations of surfaces in higher dimensional spaces. In particular, those which approximate irrational planes are non-periodic. But which ones are also aperiodic? This paper introduces the notion of subperiod, which links algebraic properties of a plane with geometric properties of the tilings that approximate it. A necessary and sufficient condition is obtained for tilings that can be seen in the four dimensional Euclidean space. This result is then applied to some examples in higher codimensions, notably tilings with n-fold rotational symmetry.
