title: Repertorio delle attribuzioni discordanti nella lirica trovierica
Creators: name: Gatti, Luca
Publisher: name: Sapienza Università Editrice
Year: 2019

description: Questione assai spinosa per gli specialisti della lirica antico-francese, il cui corpus è costituito da oltre 2.500 componimenti, è quella della paternità: il 63% dei testi è anonimo; dei rimanenti, nel 17% dei casi le rubriche dei canzonieri propongono almeno due autori. Il fenomeno delle attribuzioni discordanti, di vasta portata, non è però evidenziato a sufficienza nei repertori attualmente disponibili: in questo studio si tenta di sondarne le principali casistiche e si propone, inoltre, una schedatura dei trovieri il più possibile neutra e non viziata da giudizi precostituiti. In ultima analisi, l’escursione attributiva non sembrerebbe solo un problema ecdotico, ma anche e soprattutto la testimonianza di una vitalità letteraria.

description: A public dataset, with a variety of properties suitable for sentiment analysis [1], event prediction, trend detection and other text mining applications, is needed in order to be able to successfully perform analysis studies. The vast majority of data on social media is text-based and it is not possible to directly apply machine learning processes into these raw data, since several different processes are required to prepare the data before the implementation of the algorithms. For example, different misspellings of same word enlarge the word vector space unnecessarily, thereby it leads to reduce the success of the algorithm and increase the computational power requirement. This paper presents an improved Turkish dataset with an effective spelling correction algorithm based on Hadoop [2]. The collected data is recorded on the Hadoop Distributed File System and the text based data is processed by MapReduce programming model. This method is suitable for the storage and processing of large sized text based social media data. In this study, movie reviews have been automatically recorded with Apache ManifoldCF (MCF) [3] and data clusters have been created. Various methods compared such as Levenshtein and Fuzzy String Matching have been proposed to create a public dataset from collected data. Experimental results show that the proposed algorithm, which can be used as an open source dataset in sentiment analysis studies, have been performed successfully to the detection and correction of spelling errors.

description: Various factors influence the degree of cybersickness a user can suffer in an immersive virtual environment, some of which can be controlled without adapting the virtual environment itself. When using HMDs, one example is the size of the field of view. However, the degree to which factors like this can be manipulated without affecting the user negatively in other ways is limited. Another prominent characteristic of cybersickness is that it affects individuals very differently. Therefore, to account for both the possible disruptive nature of alleviating factors and the high interpersonal variance, a promising approach may be to intervene only in cases where users experience discomfort symptoms, and only as much as necessary. Thus, we conducted a first experiment, where the field of view was decreased when people feel uncomfortable, to evaluate the possible positive impact on sickness and negative influence on presence. While we found no significant evidence for any of these possible effects, interesting further results and observations were made.

description: In the electromechanical theory of nerve stimulation, the nerve impulse consists of a traveling region of solid membrane in a liquid environment. Therefore, the free energy necessary to stimulate a pulse is directly related to the free energy difference necessary to induce a phase transition in the nerve membrane. It is a function of temperature and pressure, and it is sensitively dependent on the presence of anesthetics which lower melting transitions. We investigate the free energy difference of solid and liquid membrane phases under the influence of anesthetics. We calculate stimulus-response curves of electromechanical pulses and compare them to measured stimulus-response profiles in lobster and earthworm axons. We also compare them to stimulus-response experiments on human median nerve and frog sciatic nerve published in the literature.

description: Big data sets must be carefully partitioned into statistically similar data subsets that can be used as representative samples for big data analysis tasks. In this paper, we propose the random sample partition (RSP) data model to represent a big data set as a set of non-overlapping data subsets, called RSP data blocks, where each RSP data block has a probability distribution similar to the whole big data set. Under this data model, efficient block level sampling is used to randomly select RSP data blocks, replacing expensive record level sampling to select sample data from a big distributed data set on a computing cluster. We show how RSP data blocks can be employed to estimate statistics of a big data set and build models which are equivalent to those built from the whole big data set. In this approach, analysis of a big data set becomes analysis of few RSP data blocks which have been generated in advance on the computing cluster. Therefore, the new method for data analysis based on RSP data blocks is scalable to big data.

description: We investigate with experiments the twist induced transverse buckling instabilities of an elastic sheet of length $L$, width $W$, and thickness $t$, that is clamped at two opposite ends while held under a tension $T$. Above a critical tension $T_λ$ and critical twist angle $η_{tr}$, we find that the sheet buckles with a mode number $n \geq 1$ transverse to the axis of twist. Three distinct buckling regimes characterized as clamp-dominated, bendable, and stiff are identified, by introducing a bendability length $L_B$ and a clamp length $L_{C}(L_B$), we find that mode $n=1$ develops above $η_{tr} \equiv η_S \sim (t/W) T^{-1/2}$, independent of $L$. In the bendable regime $L_{C} 1$ occur above $η_{tr} \equiv η_B \sim \sqrt{t/L}T^{-1/4}$. Here, we find the wavelength $λ_B \sim \sqrt{Lt}T^{-1/4}$, when $n > 1$. These scalings agree with those derived from a covariant form of the Föppl-von Kármán equations, however, we find that the $n=1$ mode also occurs over a surprisingly large range of $L$ in the bendable regime. Finally, in the clamp-dominated regime ($L < L_c$), we find that $η_{tr}$ is higher compared to $η_B$ due to additional stiffening induced by the clamped boundary conditions.

description: The UNIQUE GAMES problem is the following: we are given a graph G = (V, E), with each edge e = (u, v) having a weight we and a permutation πuv on [k]. The objective is to find a labeling of each vertex u with a label fu ∈ [k] to minimize the weight of unsatisfied edges---where an edge (u, v) is satisfied if fv = πuv(fu).The Unique Games Conjecture of Khot [8] essentially says that for each ε > 0, there is a k such that it is NP-hard to distinguish instances of Unique games with (1-ε) satisfiable edges from those with only ε satisfiable edges. Several hardness results have recently been proved based on this assumption, including optimal ones for Max-Cut, Vertex-Cover and other problems, making it an important challenge to prove or refute the conjecture.In this paper, we give an O(log n)-approximation algorithm for the problem of minimizing the number of unsatisfied edges in any Unique game. Previous results of Khot [8] and Trevisan [12] imply that if the optimal solution has OPT = εm unsatisfied edges, semidefinite relaxations of the problem could give labelings with min {k2ε1/5, (ε log n)1/2}m unsatisfied edges. In this paper we show how to round a LP relaxation to get an O(log n)-approximation to the problem; i.e., to find a labeling with only O(εm log n) = O(OPT log n) unsatisfied edges.
The neural correlates of loss of consciousness in TBI

description: Traumatic Brain Injury (TBI) is a public health issue which affects more than 60 million people per year worldwide, frequently resulting in loss of consciousness (LOC). Little is known about the biological bases of consciousness and similarly, the neurophysiological mechanisms underlying unconsciousness remain unidentified. In this study, the presence of DTI structural connectivity abnormalities in mild and moderate TBI patients who experienced LOC < 30 minutes is investigated using a graph theoretical approach to test whether the event induces any white matter alteration and identify specific brain features, encephalic regions or connectivity patterns that are related to the consciousness.

description: The current study explores the impact of the recession on the ski industry based on interviews with suppliers in two ski resorts (n=10) as well as ski travel agencies (n=8). Subsequently, Flemish ski tourists (n=252) were surveyed about changes in their behavior towards ski vacations from 2008 to 2011, taking into account their socio-cultural background as well their level of ski/snowboard participation. Both studies reveal a decline in ski tourism during the years under investigation. The impact of the recession varies according to the type of sports provider. The impact of the recession on ski vacations is more prevalent for some groups in society (e.g., households with no children, more financial constraints, lower professional status, younger people), regardless of if one is a highly motivated and/or experienced skier. This paper contributes to socio-economic theory related to the ski tourism industry and assists suppliers to identify strategies to overcome hurdles during a recession.

description: Advances in ubiquitous computing have enabled end-user authoring of context-aware policies (CAPs) that control smart devices based on specific contexts of the user and environment. However, authoring CAPs accurately and avoiding run-time errors is challenging for end-users as it is difficult to foresee CAP behaviors under complex real-world conditions. We propose Fast-Forward Reality, an Extended Reality (XR) based authoring workflow that enables end-users to iteratively author and refine CAPs by validating their behaviors via simulated unit test cases. We develop a computational approach to automatically generate test cases based on the authored CAP and the user's context history. Our system delivers each test case with immersive visualizations in XR, facilitating users to verify the CAP behavior and identify necessary refinements. We evaluated Fast-Forward Reality in a user study (N=12). Our authoring and validation process improved the accuracy of CAPs and the users provided positive feedback on the system usability.

description: Terahertz (THz) technology is critical for quantum material physics, biomedical imaging, ultrafast electronics, and next-generation wireless communications. However, standing in the way of widespread applications is the scarcity of efficient ultrafast THz sources with on-demand fast modulation and easy on-chip integration capability. Here we report the discovery of colossal THz emission from a van der Waals (vdW) ferroelectric semiconductor NbOI$_2$. Using THz emission spectroscopy, we observe a THz generation efficiency an order of magnitude higher than that of ZnTe, a standard nonlinear crystal for ultrafast THz generation. We further uncover the underlying generation mechanisms associated with its large ferroelectric polarization by studying the THz emission dependence on excitation wavelength, incident polarization and fluence. Moreover, we demonstrate the ultrafast coherent amplification and annihilation of the THz emission and associated coherent phonon oscillations by employing a double-pump scheme. These findings combined with first-principles calculations, inform new understanding of the THz light-matter interaction in emergent vdW ferroelectrics and pave the way to develop high-performance THz devices on them for quantum materials sensing and ultrafast electronics.

description: This study reexamines the spectroscopic parameters of light-flavor diquarks within the framework of quantum chromodynamics sum rules (QCDSR) using the inverse matrix method. Conventional QCDSR analyses are based on assumptions such as quark-hadron duality and continuum models, which introduce a degree of systematic uncertainty. The inverse matrix method circumvents these assumptions by reformulating the problem as an inverse integral equation and expanding the unknown spectral density using orthogonal Laguerre polynomials. This method allows for a direct determination of spectral densities, thereby enhancing the precision of predictions regarding resonance masses and decay constants. By employing this methodology with regard to light-flavor diquarks ($sq$ and $ud$), it is possible to extract the associated masses and decay constants. The results indicate that the masses of diquarks with quantum numbers $J^P = 0^+$ and $J^P = 0^-$ are nearly degenerate. We compare our results regarding masses and decay constants with those of other theoretical predictions, which could prove a useful complementary tool in interpretation. Our results are consistent with those in the literature and can be shown as evidence for the consistency of the method. The results achieved in this study highlight the potential of the inverse matrix method as a robust tool for exploring nonperturbative QCD phenomena and elucidating the internal structure of exotic hadronic systems.

description: Interactive visual media enable the visualization and navigation of remote-world locations in all gaze directions. A large segment of such media is created using pictures from the remote sites thanks to the advance in panoramic cameras. A desirable enhancement is to facilitate the stereoscopic visualization of remote scenes in all gaze directions. In this context, a model for the signal to be acquired by an omnistereoscopic sensor is needed in order to design better acquisition strategies. This omnistereoscopic viewing model must take into account the geometric constraints imposed by our binocular vision system since we want to produce stereoscopic imagery capable to induce stereopsis consistently in any gaze direction; in this paper, we present such model. In addition, we discuss different approaches to sample or to approximate this function and we propose a general acquisition model for sampling the omnistereoscopic light signal. From this model, we propose that by acquiring and mosaicking sparse sets of partially overlapped stereoscopic snapshots, a satisfactory illusion of depth can be evoked. Finally, we show an example of the rendering pipeline to create the omnistereoscopic imagery.

description: We suggest an unified presentation to teach fundamental constants to graduate students, by introducing four lower limits to observed phenomena. The reduced Planck constant $\hbar$ is the lowest classically definable action. The inverse of invariant speed, $s$, is the lowest observable slowness. The Planck time, $t_{\rm P}$, is the lowest observable time scale. The Boltzmann constant, $k$, determines the lowest coherent degree of freedom; we recall a Einstein criterion on the fluctuations of small thermal systems and show that it has far-reaching implications, such as demonstrating the relations between critical exponents. Each of these four fundamental limits enters in an inequality, which marks a horizon of the universe we can perceive. This compact presentation can resolve some difficulties encountered when trying to defining the epistemologic status of these constants, and emphasizes their useful role in shaping our intuitive vision of the universe.
Approximating TSP on Metrics with Bounded Global Growth

description: The Traveling Salesman Problem (TSP) is a canonical NP-complete problem which is known to be MAX-SNP hard even on (high-dimensional) Euclidean metrics [39]. In order to circumvent this hardness, researchers have been developing approximation schemes for low-dimensional metrics [4, 38] (under different notions of dimension). However, a feature of most current notions of metric dimension is that they are "local": the definitions require every local neighborhood to be well-behaved. In this paper, we consider the case when the metric is less restricted: it has a few "dense" regions, but is "well-behaved on the average"? To this end, we define a global notion of dimension which we call the correlation dimension (denoted by dimC), which generalizes the popular notion of doubling dimension. In fact, the class of metrics with dimC = O(1) not only contains all doubling metrics, but also contains some metrics containing uniform submetrics of size √n. We first show, using a somewhat "local" argument, that one can solve TSP on these metrics in time 2O(√n); we then take advantage of the global nature of TSP (and the global nature of our definition) to give a (1 + ε)-approximation algorithm that runs in sub-exponential time: i.e., in 2O(nδε-4dimC)-time for every constant 0 < δ < 1.

description: For a closed surface M with metric g, the Robin mass m(p) at the point p is the value of the Green function G(p,q) at p=q after the logarithmic singularity has been removed. The Laplacian-mass is the average value of the Robin mass, minus the value of the Robin mass for the round sphere of the same area. The Laplacian-mass is a spectral invariant which is a natural analog of the ADM mass for asymptotically flat manifolds. We show that if M is a torus, then the minimum value of the Laplacian-mass on the conformal class of g is negative. It is attained by a (smooth) metric for which one gets a sharp logarithmic Hardy-Littlewood-Sobolev inequality and Onofri-type inequality. If the flat metric in the conformal class is sufficiently long and thin, then the minimizer for the Laplacian-mass is non-flat.

description: A covering integer program (CIP) is a mathematical program of the form: min{c⊤x∣Ax≥1,0≤x≤u,x∈\ensuremathZn}, where A∈Rm×n≥0,c,u∈\ensuremathRn≥0. In the online setting, the constraints (i.e., the rows of the constraint matrix A) arrive over time, and the algorithm can only increase the coordinates of x to maintain feasibility. As an intermediate step, we consider solving thecovering linear program (CLP) online, where the requirement x ∈ ℤ n is replaced by x ∈ ℝ n . Our main results are (a) an O(logk)-competitive online algorithm for solving the CLP, and (b) an O(logk ·logℓ)-competitive randomized online algorithm for solving the CIP. Here k ≤ n and ℓ ≤ m respectively denote the maximum number of non-zero entries in any row and column of the constraint matrix A. By a result of Feige and Korman, this is the best possible for polynomial-time online algorithms, even in the special case of set cover (where A ∈ {0,1} m ×nand c, u ∈ {0,1} n ). The novel ingredient of our approach is to allow the dual variables to increase and decrease throughout the course of the algorithm. We show that the previous approaches, which either only raise dual variables, or lower duals only within a guess-and-double framework, cannot give a performance better than O(logn), even when each constraint only has a single variable (i.e., k = 1).

description: Imitation learning with a privileged teacher has proven effective for learning complex control behaviors from high-dimensional inputs, such as images. In this framework, a teacher is trained with privileged task information, while a student tries to predict the actions of the teacher with more limited observations, e.g., in a robot navigation task, the teacher might have access to distances to nearby obstacles, while the student only receives visual observations of the scene. However, privileged imitation learning faces a key challenge: the student might be unable to imitate the teacher's behavior due to partial observability. This problem arises because the teacher is trained without considering if the student is capable of imitating the learned behavior. To address this teacher-student asymmetry, we propose a framework for joint training of the teacher and student policies, encouraging the teacher to learn behaviors that can be imitated by the student despite the latters' limited access to information and its partial observability. Based on the performance bound in imitation learning, we add (i) the approximated action difference between teacher and student as a penalty term to the reward function of the teacher, and (ii) a supervised teacher-student alignment step. We motivate our method with a maze navigation task and demonstrate its effectiveness on complex vision-based quadrotor flight and manipulation tasks.

description: Designing revenue-maximizing combinatorial auctions (CAs) is a recognized open problem in mechanism design. It is unsolved even for two bidders and two items for sale. Rather than attempting to characterize the optimal auction, we focus on designing approximations (suboptimal auction mechanisms which yield high revenue). Our approximations belong to the family of virtual valuations combinatorial auctions (VVCA). VVCA is a Vickrey-ClarkeGroves (VCG) mechanism run on virtual valuations that are linear transformations of the bidders’ real valuations. We pursue two approaches to constructing approximately optimal CAs. The ﬁrst is to construct a VVCA with worst-case
and average-case performance guarantees. We give a logarithmic approximation auction for basic important special cases of the problem: 1) limited supply of items on sale with additive valuations and 2) unlimited supply. The second approach is to search the parameter space of VVCAs in order to obtain high-revenue mechanisms for the general problem. We introduce a series of increasingly sophisticated algorithms that use economic insights to guide the search and thus reduce the computational complexity. Our experiments demonstrate that in many cases these algorithms perform almost as well as the optimal VVCA, yield a substantial increase in revenue over the VCG mechanism and drastically outperform the straightforward algorithms in run-time.

description: The VCG mechanism is the gold standard for combinatorial auctions (CAs), and it maximizes social welfare. In contrast, the revenue-maximizing (aka optimal) CA is unknown, and designing one is NP-hard. Therefore, research on optimal CAs has progressed into special settings. Notably, Levin [1997] derived the optimal CA for complements when each agent’s private type is one-dimensional. (This does not fall inside the well-studied “singleparameter environment”.) We introduce a new research avenue for increasing revenue where we poke holes in the allocation space—based on the bids—and then use a welfare-maximizing allocation rule within the remaining allocation set. In this paper, the first step down this avenue, we introduce a new form of “reserve pricing” into CAs. We show that Levin’s optimal revenue can be 2-approximated by using “monopoly reserve prices” to curtail the allocation set, followed by welfare-maximizing allocation and Levin’s payment rule. A key lemma of potential independent interest is that the expected revenue from any truthful allocation-monotonic mechanism equals the expected virtual valuation; this generalizes Myerson’s lemma [1981] from the single-parameter environment. Our mechanism is close to the gold standard and thus easier to adopt than Levin’s. It also requires less information about the prior over the bidders’ types, and is always more efficient. Finally, we show that the optimal revenue can be 6- approximated even if the “reserve pricing” is required to be symmetric across bidders.

description: The excitonic insulator is an intriguing correlated electron phase formed of condensed excitons. A promising candidate is the small band gap semiconductor Ta2NiSe5. Here we investigate the quasiparticle and coherent phonon dynamics in Ta2NiSe5 in a time resolved pump probe experiment. Using the models originally developed by Kabanov et al. for superconductors, we show that the material's intrinsic gap can be described as almost temperature independent for temperatures up to about 250 K to 275 K. This behavior supports the existence of the excitonic insulator state in Ta2NiSe5. The onset of an additional temperature dependent component to the gap above these temperatures suggests that the material is located in the BEC-BCS crossover regime. Furthermore, we show that this state is very stable against strong photoexcitation, which reveals that the free charge carriers are unable to effectively screen the attractive Coulomb interaction between electrons and holes, likely due to the quasi one-dimensional structure of Ta2NiSe5.

description: Bus factor (BF) is a metric that tracks knowledge distribution in a project. It is the minimal number of engineers that have to leave for a project to stall. Despite the fact that there are several algorithms for calculating the bus factor, only a few tools allow easy calculation of bus factor and convenient analysis of results for projects hosted on Git-based providers.
 We introduce Bus Factor Explorer, a web application that provides an interface and an API to compute, export, and explore the Bus Factor metric via treemap visualization, simulation mode, and chart editor. It supports repositories hosted on GitHub and enables functionality to search repositories in the interface and process many repositories at the same time. Our tool allows users to identify the files and subsystems at risk of stalling in the event of developer turnover by analyzing the VCS history. The application and its source code are publicly available on GitHub at https://github.com/JetBrains-Research/bus-factor-explorer.

A construção identitária em comunidades plurais e inclusivas

Year: 2016

description: O presente trabalho propõe uma reflexão sobre os processos de construção da identidade num contexto em que as referências identitárias tradicionais estão em crise. Pensar a Educação Social e a intervenção numa perspectiva de desenvolvimento local implica a consideração de identidades culturais múltiplas em interação e, por vezes, em conflito. Neste sentido, impõe-se o desenvolvimento de uma postura reflexiva que interprete a identidade como um processo que resulta da interação entre o sujeito e o(s) seu(s) contexto(s), perspetivando a comunidade e os indivíduos numa relação dinâmica. Assim, o principal objetivo deste trabalho é conceptualizar a compreensão e o conhecimento da organização da narrativa identitária como estratégia de leitura da comunidade e de avaliação das suas fragilidades e potencialidades, no percurso de construção de comunidades verdadeiramente plurais e inclusivas. Palavras-chave: Identidades Culturais, Educação e Intervenção Social, Comunidades inclusivas e Plurais.

Topological Defects in the Georgi-Machacek Model

description: We study topological defects in the Georgi-Machacek model in a hierarchical symmetry breaking in which extra triplets acquire vacuum expectation values before the doublet. We find a possibility of topologically stable non-Abelian domain walls and non-Abelian flux tubes (vortices) in this model. In the limit of the vanishing $U(1)_{\rm Y}$ gauge coupling in which the custodial symmetry becomes exact, the presence of a vortex spontaneously breaks the custodial symmetry, giving rise to $S^2$ Nambu-Goldstone (NG) modes localized around the vortex corresponding to non-Abelian fluxes. Vortices are continuously degenerated by these degrees of freedom, thereby called non-Abelian. By taking into account the $U(1)_{\rm Y}$ gauge coupling, the custodial symmetry is explicitly broken, the NG modes are lifted, and all non-Abelian vortices fall into a topologically stable $Z$-string. This is in contrast to the SM in which $Z$-strings are non-topological and are unstable in the realistic parameter region.Non-Abelian domain walls also break the custodial symmetry and are accompanied by localized $S^2$ NG modes. Finally, we discuss the existence of domain wall solutions bounded by flux tubes, where their $S^2$ NG modes match. The domain walls may quantum mechanically decay by creating a hole bounded by a flux tube loop, and would be cosmologically safe. Gravitational waves produced from unstable domain walls could be detected by future experiments

description: Refletiremos neste artigo sobre a obra de António Torrado, destinada a um público infanto juvenil. Tendo escolhido um corpus textual que definimos em termos de contos “de exemplo”, comprovaremos de que forma(s) o autor transmite aos mais novos, mensagens de igualdade, fraternidade e respeito pela liberdade individual de todos os seres. Comprovaremos que os contos analisados obedecem a uma construção de sentidos universais, que podemos caraterizar como atemporais, embora neles não se vislumbre qualquer carga doutrinadora, mas sim o sentido de que as crianças a quem se destinam serão homens e mulheres que se pretendem conscientes da realidade que os envolve. Palavras-chave: Contos, Infância, liberdade, igualdade, fraternidade.

description: Two-dimensional spectroscopy is discussed for open quantum systems with multiple simultaneously measurable fluxes. In particular, we discuss a junction where optical measurements of photon flux are complemented with simultaneous transport measurements of electron currents. Theory of two-dimensional spectroscopy in both fluxes is developed employing non-self-consistent nonequilibrium Green's function formulation. Theoretical derivations are illustrated with numerical simulations within generic junction model.

i-Process Contribution of Rapidly Accreting White Dwarfs to the Solar Composition of First-Peak Neutron-Capture Elements

description: Rapidly accreting white dwarfs (RAWDs) have been proposed as contributors to the chemical evolution of heavy elements in the Galaxy. Here, we test this scenario for the first time and determine the contribution of RAWDs to the solar composition of first-peak neutron-capture elements. We add the metallicity-dependent contribution of RAWDs to the one-zone galactic chemical evolution code OMEGA according to RAWD rates from binary stellar population models combined with metallicity-dependent $i$-process stellar yields calculated following the models of Denissenkov et al. (2017). With this approach we find that the contribution of RAWDs to the evolution of heavy elements in the Galaxy could be responsible for a significant fraction of the solar composition of Kr, Rb, Sr, Y, Zr, Nb, and Mo ranging from $2$ to $45\%$ depending on the element, the enrichment history of the Galactic gas, and the total mass ejected per RAWD. This contribution could explain the missing solar Lighter Element Primary Process for some elements (e.g., Sr, Y, and Zr). We do not overproduce any isotope relative to the solar composition, but $^{96}$Zr is produced in a similar amount. The $i$ process produces efficiently the Mo stable isotopes $^{95}$Mo and $^{97}$Mo. When nuclear reaction rate uncertainties are combined with our GCE uncertainties, the upper limits for the predicted RAWD contribution increase by a factor of $1.5-2$ for Rb, Sr, Y, and Zr, and by 3.8 and 2.4 for Nb and Mo, respectively. We discuss the implication of the RAWD stellar evolution properties on the single degenerate Type Ia supernova scenario.

Approximating Non-Uniform Sparsest Cut via Generalized Spectra

description: We give an approximation algorithm for non-uniform sparsest cut with the following guarantee: For any ε, δ ∊ (0, 1), given cost and demand graphs with edge weights respectively, we can find a set T ⊆ V with at most times the optimal non-uniform sparsest cut value, in time 2r/(δε) poly(n) provided Λr ≥ Φ*/(1 − δ). Here Λr is the r'th smallest generalized eigenvalue of the Laplacian matrices of cost and demand graphs; C(T, V \ T) (resp. D(T, V \ T)) is the weight of edges crossing the (T, V \ T) cut in cost (resp. demand) graph and Φ* is the sparsity of the optimal cut. In words, we show that the non-uniform sparsest cut problem is easy when the generalized spectrum grows moderately fast. To the best of our knowledge, there were no results based on higher order spectra for non-uniform sparsest cut prior to this work. Even for uniform sparsest cut, the quantitative aspects of our result are somewhat stronger than previous methods. Similar results hold for other expansion measures like edge expansion, normalized cut, and conductance, with the r'th smallest eigenvalue of the normalized Laplacian playing the role of Λr(G) in the latter two cases. Our proof is based on an ℓ1-embedding of vectors from a semi-definite program from the Lasserre hierarchy. The embedded vectors are then rounded to a cut using standard threshold rounding. We hope that the ideas connecting ℓ1-embeddings to Lasserre SDPs will find other applications. Another aspect of the analysis is the adaptation of the column selection paradigm from our earlier work on rounding Lasserre SDPs [9] to pick a set of edges rather than vertices. This feature is important in order to extend the algorithms to non-uniform sparsest cut.
Observation of the $K^{+}\rightarrowπ^{+}ν\barν$ decay and measurement of its branching ratio

description: A measurement of the $K^{+}\rightarrowπ^{+}ν\barν$ decay by the NA62 experiment at the CERN SPS is presented, using data collected in 2021 and 2022. This dataset was recorded, after modifications to the beamline and detectors, at a higher instantaneous beam intensity with respect to the 2016--2018 data taking. Combining NA62 data collected in 2016--2022, a measurement of $B(K^{+}\rightarrowπ^{+}ν\barν) = \left( 13.0^{+ 3.3}_{- 3.0} \right)\times10^{-11}$ is reported. With $51$ signal candidates observed and an expected background of $18^{+3}_{-2}$ events, $B(K^{+}\rightarrowπ^{+}ν\barν)$ becomes the smallest branching ratio measured with a signal significance above $5\,σ$.
