description: In-beam $ γ$-ray spectroscopy of $^{131}$Xe has been carried out to study the structure of the intruder $ νh_{11/2} $ band. Excited states were populated via an $ α$-induced fusion-evaporation reaction at E$ _α = 38 $ MeV. Inspection of $ γγ$-coincidence data resulted in the identification of a new rotational sequence. Based on the systematics of excitation energy, assigned spin-parity, decay pattern, and the electromagnetic character of the inter-band $ ΔI = 1 $ $ γ$-transitions, this sequence is proposed as the unfavoured signature partner of the $ νh_{11/2} $ band. The structure of this band is further illuminated in the light of the triaxial particle rotor model (TPRM). The possibility of wobbling excitation in $ N = 77 $ Xe-Ba-Ce isotones has been explored in a systematic manner.

description: Back in 1964, the theoretical physicists Francois Englert and Robert Brout, as well as Peter Higgs, suggested an explanation for the fact that most elementary particles - such as the electron - have a mass. This scenario predicted a new particle, which has been observed experimentally only just now at CERN (the European Organization for Nuclear Research). This discovery led to the Physics Nobel Prize 2013. Here we sketch in simple terms the concept of the Higgs mechanism, and its importance in particle physics.

description: Με αφορμή το θέμα που επιλέχθηκε για την εκπόνηση της ερευνητικής εργασίας (‘Αρχιτεκτονική και Ψυχολογία: Διαβίωση σε ακραίες συνθήκες εγκλεισμού’) και την προσωπική επιθυμία και ανάγκη για περαιτέρω ανάλυση και ενδοσκόπηση στο ζήτημα -και τις κατ’ επέκταση δυναμικές που δημιουργούνται, γίνεται μία προσπάθεια σχεδίασης του εσωτερικού ενός ήδη υπάρχοντος υποβρυχίου.
Σκοπός είναι η δημιουργία χώρων οι οποίοι, παρά τις αντίξοες συνθήκες εγκλεισμού, να προσελκύουν τον χρήση ώστε να βιώσει την εμπειρία κατοίκησης σε ένα υποβρύχιο. Διατηρώντας το κέλυφος σχεδόν ως έχει και τα μηχανολογικά του μέρη άθικτα, αφαιρείται οτιδήποτε θύμιζε έως τώρα τη στρατιωτική/ναυτική του χρήση και δίνεται μία νέα δυνατότητα επανάχρησης του.
Μέσω προτάσεων και εναλλακτικών σχεδίασης ενός υποβρύχιου στενού χώρου, και ως βασικό εργαλείο στη σχεδίασή του, τα συμπεράσματα που προέκυψαν από την ερευνητική εργασία, δίνεται έμφαση σε χωρικές ποιότητες και χαρακτηριστικά τα οποία, αντί να τονίζουν την έλλειψη χώρου και άνεσης, την ενισχύουν και καλλιεργούν την αίσθηση της ‘φωλιάς’, ιδιωτικότητας και οικειότητας στο χώρο.

description: From the initial conclusions of the research ‘Architecture and Psychology: Living in Confined Spaces’, the project moved towards a proposal that gave emphasis on spatial qualities such as visual “temperature”, intensity and color of light, audio landscape, tactile textures and generally spatial features/characteristics that contribute to the sensation of the habitation archetype. A rough retrofitting framework was produced that led to a proposal of a different type of utilization of submarine chassis. The proposal presents an alternative use of a submarine, as a novel habitation “nest” ,  focusing in the design of spaces that exhibit the qualitative elements of “place”, using narrow spaces as an advantage.

description: A detailed understanding of all effects and influences on higher-order correlations is essential. At low charged multiplicity, the effect of a nonpoissonian multiplicity distribution can significantly distort correlations. Evidently, the reference samples with respect to which correlations are measured should yield a null result in the absence of correlations. We show how the careful specification of desired properties necessarily leads to an average-of-multinomials reference sample. The resulting internal cumulants and their averaging over several multiplicities fulfil all requirements of correctly taking into account nonpoissonian multiplicity distributions as well as yielding a null result for uncorrelated fixed-N samples. Various correction factors are shown to be approximations at best. Careful rederivation of statistical variances and covariances within the frequentist approach yields errors for cumulants that differ from those used so far. We finally briefly discuss the implementation of the analysis through a multiple event buffer algorithm.

description: Timely treatment of stroke is critical to minimize brain damage. Therefore, efforts are being made to educate the public on detecting stroke symptoms, e.g., face, arms, and speech test (FAST). In this position paper, we propose to perform the arm weakness test using the integrated video tracking from an iPhone - some general tests to assess the tracking quality and discuss potential critical points. The test has been performed on 4 stroke patients. The result is compared with the report of the clinician. Although presenting some limitations, the system proved to be able to detect arm weakness as a symptom of stroke. We envisage that introducing a portable body tracking system in such clinical tests will provide advantages in terms of objectivity, repeatability, and the possibility to record and compare groups of patients.

description: In the Graph Isomorphism problem two N-vertex graphs G and G' are given and the task is to determine whether there exists a permutation of the vertices of G that preserves adjacency and transforms G into G'. If yes, then G and G' are said to be isomorphic; otherwise they are non-isomorphic. The GI problem is an important problem in computer science and is thought to be of comparable difficulty to integer factorization. In this paper we present a quantum algorithm that solves arbitrary instances of GI and can also determine all automorphisms of a given graph. We show how the GI problem can be converted to a combinatorial optimization problem that can be solved using adiabatic quantum evolution. We numerically simulate the algorithm's quantum dynamics and show that it correctly: (i) distinguishes non-isomorphic graphs; (ii) recognizes isomorphic graphs; and (iii) finds all automorphisms of a given graph G. We then discuss the GI quantum algorithm's experimental implementation, and close by showing how it can be leveraged to give a quantum algorithm that solves arbitrary instances of the NP-Complete Sub-Graph Isomorphism problem.

In particular, we determine some of the parameters of the codes arising from the projective system determined by $\varepsilon_k^{gr}(Δ_k)$. We also study special sets of points of $Δ_k$ which are met by any line of $Δ_k$ in at most 2 points and we show that their image under the Grassmann embedding $\varepsilon_k^{gr}$ is a projective cap.

description: A novel method to generate and manipulate vector vortex beams in an integrated, ring resonator based geometry is proposed. We show numerically that a ring resonator, with an appropriate grating, addressed by a vertically displaced access waveguide emits a complex optical field. The emitted beam possesses a specific polarization topology, and consequently a transverse intensity profile and orbital angular momentum. We propose a combination of several concentric ring resonators, addressed with different bus guides, to generate arbitrary orbital angular momentum qudit states, which could potentially be used for classical and quantum communications. Finally, we demonstrate numerically that this device works as an orbital angular momentum sorter with an average cross-talk of -10 dB between different orbital angular momentum channels.

Non-mean-field Critical Exponent in a Mean-field Model : Dynamics versus Statistical Mechanics

description: The mean-field theory tells that the classical critical exponent of susceptibility is the twice of that of magnetization. However, the linear response theory based on the Vlasov equation, which is naturally introduced by the mean-field nature, makes the former exponent half of the latter for families of quasistationary states having second order phase transitions in the Hamiltonian mean-field model and its variances. We clarify that this strange exponent is due to existence of Casimir invariants which trap the system in a quasistationary state for a time scale diverging with the system size. The theoretical prediction is numerically confirmed by $N$-body simulations for the equilibrium states and a family of quasistationary states.

Numerical simulation of ejected molten metal-nanoparticles liquefied by laser irradiation: Interplay of geometry and dewetting

description: Metallic nanoparticles, liquefied by fast laser irradiation, go through a rapid change of shape attempting to minimize their surface energy. The resulting nanodrops may be ejected from the substrate when the mechanisms leading to dewetting are sufficiently strong, as in the experiments involving gold nanoparticles [Habenicht et al., Science 309, 2043 (2005)]. We use a direct continuum-level approach to accurately model the process of liquid nanodrop formation and the subsequent ejection from the substrate. Our computations show a significant role of inertial effects and an elaborate interplay of initial geometry and wetting properties: e.g., we can control the direction of ejection by prescribing appropriate initial shape and/or wetting properties. The basic insight regarding ejection itself can be reached by considering a simple effective model based on an energy balance. We validate our computations by comparing directly with the experiments specified above involving the length scales measured in hundreds of nanometers, and with molecular dynamics simulations on much shorter scales measured in tens of atomic diameters, as in [M. Fuentes-Cabrera et al., Phys. Rev. E 83, 041603 (2011)]. The quantitative agreement, in addition to illustrating how to controlling particle ejection, shows utility of continuum-based simulation in describing dynamics on nanoscale quantitatively, even in a complex setting as considered here.

description: Patchy particles are a popular paradigm for the design and synthesis of nanoparticles and colloids for self-assembly. In "traditional" patchy particles, anisotropic interactions arising from patterned coatings, functionalized molecules, DNA, and other enthalpic means create the possibility for directional binding of particles into higher-ordered structures. Although the anisotropic geometry of non-spherical particles contributes to the interaction patchiness through van der Waals, electrostatic, and other interactions, how particle shape contributes entropically to self-assembly is only now beginning to be understood. It has been recently demonstrated that, for hard shapes, entropic forces are directional. A newly proposed theoretical framework that defines and quantifies directional entropic forces demonstrates the anisotropic--that is, patchy--nature of these emergent, attractive forces. Here we introduce the notion of entropically patchy particles as the entropic counterpart to enthalpically patchy particles. Using three example "families" of shapes, we judiciously modify entropic patchiness by introducing geometric features to the particles so as to target specific crystal structures, which then assembled with Monte Carlo simulations. We quantify the emergent entropic valence via a potential of mean force and torque. We generalize these shape operations to shape anisotropy dimensions, in analogy with the anisotropy dimensions introduced for enthalpically patchy particles. Our findings demonstrate that entropic patchiness and emergent valence provide a way of engineering directional bonding into nanoparticle systems, whether in the presence or absence of additional, non-entropic forces.

description: Investment is a critical component of sustainable development. In particular, under the right conditions, foreign direct investment (FDI) can improve economic growth and living standards, create jobs, transfer technology and know-how and result in supply chain upgrading. However, its benefits are not automatic, and, if not carefully governed, investment can result in harm to the environment, labour standards and lead to tax evasion or other undesirable outcomes. Investment promotion and investment facilitation, in turn, can help states attract, expand and retain FDI. CCSI works on analyzing how investment promotion and facilitation measures can advance sustainable development objectives and created this briefing note on investment promotion and facilitation for sustainable development in July 2020.

CCSI’s submission focused on challenges associated with implementing, and auditing for compliance with, three aspects of Bonsucro’s draft standard, namely: obtaining the free, prior and informed consent (FPIC) of Indigenous and traditional communities when establishing or expanding sugar production operations; implementing transparent and participatory processes to assess, monitor, and evaluate the environmental and social impacts of new and existing projects; and establishing accessible dispute resolution and grievance mechanisms that allow communities to raise and resolve problems.The submission proposed a concrete solution to complement Bonsucro operators’ efforts to more effectively meet that Standard in practice: a Basket Fund for Responsible Investment.

In this short essay, one of the book’s authors joins with a librarian to provide updated and revised thoughts on the role of librarians in guided pathways. First, the authors discuss the importance of embedding critical thinking into guided pathways curricula and librarians’ unique position to support that goal. Then they discuss various models by which colleges might leverage librarians’ expertise and which models seem more or less compatible with the guided pathways framework.

The information base of a human model changes over time but also his mood and his ability to accept information. An information provision strategy should hence take such aspects into account. In this paper, we describe our vision of an approach to aid the design of CIS. We envision using psychological models of the human mind and emotions in an information provision game. Its analysis gives comparative insights into design variants.

description: Trust is a crucial component in collaborative multiagent systems (MAS) involving humans and autonomous AI agents. Rather than assuming trust based on past system behaviours, it is important to formally verify trust by modelling the current state and capabilities of agents. We argue for verifying actual trust relations based on agents abilities to deliver intended outcomes in specific contexts. To enable reasoning about different notions of trust, we propose using the refinement-based formal method Event-B. Refinement allows progressively introducing new aspects of trust from abstract to concrete models incorporating knowledge and runtime states. We demonstrate modelling three trust concepts and verifying associated trust properties in MAS. The formal, correctness-by-construction approach allows to deduce guarantees about trustworthy autonomy in human-AI partnerships. Overall, our contribution facilitates rigorous verification of trust in multiagent systems.

description: Context-Free Grammars (CFGs) and Parsing Expression Grammars (PEGs) have several similarities and a few differences in both their syntax and semantics, but they are usually presented through formalisms that hinder a proper comparison. In this paper we present a new formalism for CFGs that highlights the similarities and differences between them. The new formalism borrows from PEGs the use of parsing expressions and the recognition-based semantics. We show how one way of removing non-determinism from this formalism yields a formalism with the semantics of PEGs. We also prove, based on these new formalisms, how LL(1) grammars define the same language whether interpreted as CFGs or as PEGs, and also show how strong-LL(k), right-linear, and LL-regular grammars have simple language-preserving translations from CFGs to PEGs.

description: A Growing Chorus is a practice-based and interdisciplinary study into the theory and practices of the commons to enquire whether these might incorporate nonhuman, as well as human, lives and activities. It is carried out through a durational and dialogical engagement with a housing estate in South London and the activities of a gardening group based there. It places this small-scale engagement in relationship to large-scale ecological crises.A methodology based on Donna Haraway’s ‘situated knowledges’ accommodates the perspective of the researcher as an artist resident at the site of research and ‘full member’ of the gardening group. It tests theory against practice on the ground, and combines a subjective viewpoint with different voices from the estate and gardens, archival material, art practices, science and theory. Approaches derived from dialogical art practice are deployed in the context of community gardening to establish a foundation of human solidarity from which the capacity of humans to recognise the role of nonhumans in their garden commons is explored.Having examined the role of human perception in relation to ecologically destructive behaviours, and the limitations of the commons in a context of climate and ecological crisis, the study proposes an attunement to symbiotic relations through the garden and a noticing of the ‘polyphony’, after Anna Tsing, of human–nonhuman activities. Clarice Allgood’s ‘perceptual commons’ and an attention to sound, drawing on acoustic ecology, provide an arena in which these might be recognised. Finally Pauline Oliveros’s Deep Listening is tested as a means of changing habits of perception, enabling humans to perceive and participate in the polyphonic commons of the garden.

description: The fluctuations in the temperature and polarization of the cosmic microwave background are described by a hierarchy of Boltzmann equations. In its integral form, this Boltzmann hierarchy can be converted from the usual Fourier-space base into a position-space and causal description. We show that probability densities for random flights play a key role in this description. The integral system can be treated as a perturbative series in the number of steps of the random flights, and the properties of random flight probabilities impose constraints on the domains of dependence. We show that, as a result of these domains, a Fourier-Bessel decomposition can be employed in order to calculate the random flight probability densities. We also illustrate how the H-theorem applies to the cosmic microwave background: by using analytical formulae for the asymptotic limits of these probability densities, we show that, as the photon distribution approaches a state of equilibrium, both the temperature anisotropies and the net polarization must vanish.

description: There is considerable industrial interest in integrating AI techniques into railway systems, notably for fully autonomous train systems. The KI-LOK research project is involved in developing new methods for certifying such AI-based systems. Here we explore the utility of a certified control architecture for a runtime monitor that prevents false positive detection of traffic signs in an AI-based perception system. The monitor uses classical computer vision algorithms to check if the signs -- detected by an AI object detection model -- fit predefined specifications. We provide such specifications for some critical signs and integrate a Python prototype of the monitor with a popular object detection model to measure relevant performance metrics on generated data. Our initial results are promising, achieving considerable precision gains with only minor recall reduction; however, further investigation into generalization possibilities will be necessary.

description: In this paper, we show how model checking can be used to create multi-step plans for a differential drive wheeled robot so that it can avoid immediate danger. Using a small, purpose built model checking algorithm in situ we generate plans in real-time in a way that reflects the egocentric reactive response of simple biological agents. Our approach is based on chaining temporary control systems which are spawned to eliminate disturbances in the local environment that disrupt an autonomous agent from its preferred action (or resting state). The method involves a novel discretization of 2D LiDAR data which is sensitive to bounded stochastic variations in the immediate environment. We operationalise multi-step planning using invariant checking by forward depth-first search, using a cul-de-sac scenario as a first test case. Our results demonstrate that model checking can be used to plan efficient trajectories for local obstacle avoidance, improving on the performance of a reactive agent which can only plan one step. We achieve this in near real-time using no pre-computed data. While our method has limitations, we believe our approach shows promise as an avenue for the development of safe, reliable and transparent trajectory planning in the context of autonomous vehicles.

description: Corequisite remediation, which mainstreams students deemed academically underprepared into college-level courses with additional learning support, is rapidly being adopted by colleges across the nation. This paper provides the first causal evidence on a system-wide corequisite reform, using data from all 13 community colleges affiliated with the Tennessee Board of Regents. Using regression discontinuity and difference-in-regression-discontinuity designs, the authors estimated the causal effects of placement into corequisite remediation compared with placement into traditional prerequisite remediation and direct placement into college-level courses. For students on the margin of the college readiness threshold, those placed into corequisite remediation were 15 percentage points more likely to pass gateway math and 13 percentage points more likely to pass gateway English within one year of enrollment than similar students placed into prerequisite remediation. Compared with their counterparts placed directly into college-level courses, students placed into corequisite remediation had similar gateway course completion rates and were about 8 percentage points more likely to enroll in and pass a subsequent college-level math course after completing gateway math. The positive effects of corequisite remediation compared with prerequisite remediation in math were largely driven by efforts to guide students to take math courses aligned with the requirements for their program rather than placing most students into the algebra–calculus track by default, as has been the standard practice. The authors found no significant impacts of placement into corequisite remediation on enrollment persistence, transfer to a four-year college, or degree completion. This suggests that corequisite reforms, though effective in helping students pass college-level math and English, are not sufficient to improve college completion rates overall.

description: Color is an interpretation of our environment but is not completely revealing by itself of the deeper 'truths' that help form it, such as the interaction of light with matter.
In this thesis we study how color stimulus is formed and research how we can optimally reproduce it. Spectroscopic  measurements were performed to determine the spectral reflectances of Colorimetric charts, standards in the color science world. Various common and scientific light sources are measured to determine their Spectral Power Distribution, which can be used as a tool for detecting the illumination in unknown conditions. A practical Snapshot Multispectral method is described, and used to produce high fidelity color results of scenes, regardless of the illumination. We elaborate on how to overcome problems inherent to the color production such as metamerism.
Gravitational Wave Signatures from Low-mode Spiral Instabilities in Rapidly Rotating Supernova Cores

description: We study properties of gravitational waves (GWs) from rotating core-collapse of a 15M_odot star by performing three-dimensional general-relativistic hydrodynamic simulations with an approximate neutrino transport. By parametrically changing the precollapse angular momentum, we focus on the effects of rotation on the GW signatures in the early postbounce evolution. Regarding three-flavor neutrino transport, we solve the energy-averaged set of radiation energy and momentum based on the Thorne's momentum formalism. In addition to the gravitational quadrupole radiation from matter motions, we take into account GWs from anisotropic neutrino emission. With these computations, our results present several supporting evidences for the previous anticipation that non-axisymmetric instabilities play an essential role in determining the postbounce GW signatures. During prompt convection, we find that the waveforms show narrow-band and highly quasi-periodic signals which persist until the end of simulations. We point out that such feature reflects the growth of the one-armed spiral modes. The typical frequency of the quasi-periodic waveforms can be well explained by the propagating acoustic waves between the stalled shock and the rotating proto-neutron star surface, which suggests the appearance of the standing-accretion-shock instability. Although the GW signals exhibit strong variability between the two polarizations and different observer directions, they are within the detection limits of next generation detectors such as by KAGRA and Advanced LIGO, if the source with sufficient angular momentum is located in our Galaxy.

description: This paper presents an optimisation-based approach for an obstacle avoidance problem within an autonomous vehicle racing context. Our control regime leverages online reachability analysis and sensor data to compute the maximal safe traversable region that an agent can traverse within the environment. The idea is to first compute a non-convex safe region, which then can be convexified via a novel coupled separating hyperplane algorithm. This derived safe area is then used to formulate a nonlinear model-predictive control problem that seeks to find an optimal and safe driving trajectory. We evaluate the proposed approach through a series of diverse experiments and assess the runtime requirements of our proposed approach through an analysis of the effects of a set of varying optimisation objectives for generating these coupled hyperplanes.

Feedstocks for biogas and how it replaces 50% of US transportation fuels

Publisher: name: Zenodo
Year: 2015

description: The U.S. has significant resources for the production of biogas (an advanced biofuel), including energy crops, crop residues, manure, organic waste streams, landfill gas and stranded methane. Until now, there has not been a complete, county by county accounting of the biogas resources, potential and its economic impact, necessary to inform and drive decision makers to support policy and industry. The opportunity lies in replacing 50% of fossil transportation fuel with renewable, domestic, advanced biofuels, using proven technology at compelling economics for investors and consumers, while creating a significant number of jobs in rural economies, and lowering the U.S. green house gas (methane) footprint with low carbon fuels.

description: We show that the extrinsic spin Hall effect can be engineered in monolayer graphene by decoration with small doses of adatoms, molecules, or nanoparticles originating local spin-orbit perturbations. The analysis of the single impurity scattering problem shows that intrinsic and Rashba spin-orbit local couplings enhance the spin Hall effect via skew scattering of charge carriers in the resonant regime. The solution of the transport equations for a random ensemble of spin-orbit impurities reveals that giant spin Hall currents are within the reach of the current state of the art in device fabrication. The spin Hall effect is robust with respect to thermal fluctuations and disorder averaging.
