description: A Viterbi-like decoding algorithm is proposed in this paper for generalized convolutional network error correction coding. Different from classical Viterbi algorithm, our decoding algorithm is based on minimum error weight rather than the shortest Hamming distance between received and sent sequences. Network errors may disperse or neutralize due to network transmission and convolutional network coding. Therefore, classical decoding algorithm cannot be employed any more. Source decoding was proposed by multiplying the inverse of network transmission matrix, where the inverse is hard to compute. Starting from the Maximum A Posteriori (MAP) decoding criterion, we find that it is equivalent to the minimum error weight under our model. Inspired by Viterbi algorithm, we propose a Viterbi-like decoding algorithm based on minimum error weight of combined error vectors, which can be carried out directly at sink nodes and can correct any network errors within the capability of convolutional network error correction codes (CNECC). Under certain situations, the proposed algorithm can realize the distributed decoding of CNECC.

description: Quantum Monte Carlo simulations provide one of the more powerful and versatile numerical approaches to condensed matter systems. However, their application to frustrated quantum spin models, in all relevant temperature regimes, is hamstrung by the infamous "sign problem." Here we exploit the fact that the sign problem is basis-dependent. Recent studies have shown that passing to a dimer (two-site) basis eliminates the sign problem completely for a fully frustrated spin model on the two-leg ladder. We generalize this result to all partially frustrated two-leg spin-1/2 ladders, meaning those where the diagonal and leg couplings take any antiferromagnetic values. We find that, although the sign problem does reappear, it remains remarkably mild throughout the entire phase diagram. We explain this result and apply it to perform efficient quantum Monte Carlo simulations of frustrated ladders, obtaining accurate results for thermodynamic quantities such as the magnetic specific heat and susceptibility of ladders up to L=200 rungs (400 spins 1/2) and down to very low temperatures.

description: The excited states of polyatomic systems are rather complex, and often exhibit meta-stable dynamical behaviors. Static analysis of reaction pathway often fails to sufficiently characterize excited state motions due to their highly non-equilibrium nature. Here, we proposed a time series guided clustering algorithm to generate most relevant meta-stable patterns directly from ab initio dynamic trajectories. Based on the knowledge of these meta-stable patterns, we suggested an interpolation scheme with only a concrete and finite set of known patterns to accurately predict the ground and excited state properties of the entire dynamics trajectories. As illustrated with the example of sinapic acids, the estimation error for both ground and excited state is very close, which indicates one could predict the ground and excited state molecular properties with similar accuracy. These results may provide us some insights to construct an excited state force field with compatible energy terms as traditional ones.

description: Models of human musculoskeletal tissue are the missing component needed to make significant advances in clinical orthopedics. Developing these models requires an in-depth knowledge of techniques and procedures which are rarely considered or taught in universities. Essential skills like deriving the foundational physics and the constitutive theory from first principles are the building blocks which will deliver future models or ligaments, tendons, and muscles. This thesis presents the first step in a journey to understand these modeling techniques in order to move toward developing a model of human tissue. The material utilized in the experiments was recipe of Ecoflex 00-20 which represents an idealized example of a large deformation viscoelastic solid. The Finite Strain Viscoelastic constitutive law was derived from first principles, uni-axial tension experiments provided the raw data, and the constitutive laws were fit to the data. The derived model outperformed most of the models with some exceptions described in the results. These results justify the development of more complicated models and experiments such as modeling surface field data and considering more complicated material properties.

description: In this paper we enumerate nonhyperelliptic superspecial curves of genus $4$ over prime fields of characteristic $p\le 11$. Our algorithm works for nonhyperelliptic curves over an arbitrary finite field in characteristic $p \ge 5$. We execute the algorithm for prime fields of $p\le 11$ with our implementation on a computer algebra system Magma. Thanks to the fact that the cardinality of $\mathbb{F}_{p^a}$-isomorphism classes of superspecial curves over $\mathbb{F}_{p^a}$ of a fixed genus depends only on the parity of $a$, this paper contributes to the odd-degree case for genus $4$, whereas our previous paper contributes to the even-degree case.

description: Variable stiffness actuators undergo lower peak force in contacts compared to their rigid counterparts, and are thus safer for human-robot interaction. Furthermore, they can store energy in their elastic element and can release it later to achieve human-like dynamic movements. However, it is not clear how to integrate them in teleoperator systems so that they can be controlled intuitively by a human. We performed an experiment to study human use of elastic tools to determine how a teleoperator system with an elastic slave would need to be designed. For this, we had 13 untrained participants hammer with an elastic tool under different stiffness conditions, asking them to try to find the best timing for a backward-forward swing motion in order to achieve the strongest impact. We found that the participants generally executed the task efficiently after a few trials and they converged to very similar solutions. The stiffness influenced the performance slightly, a stiffness between 2.3 Nm/rad and 4.1 Nm/rad showing the best results. We conclude that humans intuitively know how to efficiently use elastic tools for hammering type tasks. This could facilitate the control of teleoperator systems with elastic slave manipulators for tasks requiring explosive movements like hammering.

description: We examine the relationship between social structure and sentiment through the analysis of a large collection of tweets about the Irish Marriage Referendum of 2015. We obtain the sentiment of every tweet with the hashtags #marref and #marriageref that was posted in the days leading to the referendum, and construct networks to aggregate sentiment and use it to study the interactions among users. Our results show that the sentiment of mention tweets posted by users is correlated with the sentiment of received mentions, and there are significantly more connections between users with similar sentiment scores than among users with opposite scores in the mention and follower networks. We combine the community structure of the two networks with the activity level of the users and sentiment scores to find groups of users who support voting `yes' or `no' in the referendum. There were numerous conversations between users on opposing sides of the debate in the absence of follower connections, which suggests that there were efforts by some users to establish dialogue and debate across ideological divisions. Our analysis shows that social structure can be integrated successfully with sentiment to analyse and understand the disposition of social media users. These results have potential applications in the integration of data and meta-data to study opinion dynamics, public opinion modelling, and polling.

Analyzing the Relationship between Project Productivity and Environment Factors in the Use Case Points Method

Year: 2017

description: Project productivity is a key factor for producing effort estimates from Use Case Points (UCP), especially when the historical dataset is absent. The first versions of UCP effort estimation models used a fixed number or very limited numbers of productivity ratios for all new projects. These approaches have not been well examined over a large number of projects so the validity of these studies was a matter for criticism. The newly available large software datasets allow us to perform further research on the usefulness of productivity for effort estimation of software development. Specifically, we studied the relationship between project productivity and UCP environmental factors, as they have a significant impact on the amount of productivity needed for a software project. Therefore, we designed four studies, using various classification and regression methods, to examine the usefulness of that relationship and its impact on UCP effort estimation. The results we obtained are encouraging and show potential improvement in effort estimation. Furthermore, the efficiency of that relationship is better over a dataset that comes from industry because of the quality of data collection. Our comment on the findings is that it is better to exclude environmental factors from calculating UCP and make them available only for computing productivity. The study also encourages project managers to understand how to better assess the environmental factors as they do have a significant impact on productivity

description: We present a clustering comparison of 12 galaxy formation models (including Semi-Analytic Models (SAMs) and Halo Occupation Distribution (HOD) models) all run on halo catalogues and merger trees extracted from a single ΛCDM N-body simulation. We compare the results of the measurements of the mean halo occupation numbers, the radial distribution of galaxies in haloes and the 2-Point Correlation Functions (2PCF). We also study the implications of the different treatments of orphan (galaxies not assigned to any dark matter subhalo) and non-orphan galaxies in these measurements. Our main result is that the galaxy formation models generally agree in their clustering predictions but they disagree significantly between HOD and SAMs for the orphan satellites. Although there is a very good agreement between the models on the 2PCF of central galaxies, the scatter between the models when orphan satellites are included can be larger than a factor of 2 for scales smaller than 1 Mpc/h. We also show that galaxy formation models that do not include orphan satellite galaxies have a significantly lower 2PCF on small scales, consistent with previous studies. Finally, we show that the 2PCF of orphan satellites is remarkably different between SAMs and HOD models. Orphan satellites in SAMs present a higher clustering than in HOD models because they tend to occupy more massive haloes. We conclude that orphan satellites have an important role on galaxy clustering and they are the main cause of the differences in the clustering between HOD models and SAMs.

description: We have performed high-resolution angle-resolved photoemission spectroscopy (ARPES) on trigonal tellurium consisting of helical chains in the crystal. Through the band-structure mapping in the three-dimensional Brillouin zone, we found a definitive evidence for the band splitting originating from the chiral nature of crystal. A direct comparison of the band dispersion between the ARPES results and the first-principles band-structure calculations suggests the presence of Weyl nodes and tiny spin-polarized hole pockets around the H point. The present result opens a pathway toward studying the interplay among crystal symmetry, band structure, and exotic physical properties in chiral crystals.

description: La présente fiche indicateur candidat concerne l’évaluation de l’état de santé des poissons par rapport aux effets des contaminants chimiques, à travers des mesures de biomarqueurs sur des poissons plats. Les données proviennent de campagnes océanographiques organisées dans le cadre du Suivi des Effets bioLogiques Induits par la contamination chimique (SELI) en baie de Seine et autour des estuaires de la Loire et de la Vilaine. Deux unités marines de rapportage (UMR) sont considérées. Elles correspondent aux zones de prospection des campagnes SELISeine et SELILoire pour chacune des sous-régions marines (SRM) Manche-Mer du Nord (MMN) et Golfe de Gascogne Nord (GdG) respectivement.
Un indice multimétrique de santé des poissons a été développé pour combiner les résultats de six biomarqueurs mesurés sur un minimum de 8 individus par zone d’évaluation. Les valeurs de chaque biomarqueur ont été classées en notes allant de 1 à 5, avec un bon état atteint lorsque la note est égale ou supérieure à 4,00. Cet indice a été appliqué à trois espèces de poisson plat : la sole (dans les deux UMR), le flet et la limande (dans l’UMR SELISeine uniquement).
La santé des poissons semble affectée par des effets cytotoxiques et neurotoxiques pour les 3 espèces, et génotoxiques pour la sole. La sole est l’espèce dont la santé apparait la plus dégradée et n’est en bon état dans aucune des deux UMR (note = 3,45 pour SELISeine et 3,53 pour SELILoire). Le flet est en bon état (note = 4,00) contrairement à la limande (note = 3,95) dans l’UMR SELISeine. Une évaluation intégrée de l’état de santé des différentes espèces au regard des paramètres écotoxicologiques et des concentrations en contaminants chimiques est discutée dans le rapport scientifique (Mauffret et al., 2023).

description: We propose gravitational microlensing as a way of testing the emergent gravity theory recently proposed by Eric Verlinde~\cite{Verlinde:2016toy}. We consider two limiting cases: the dark mass of maximally anisotropic pressures (Case I) and of isotropic pressures (Case II). Our analysis of perihelion advancement of a planet shows that only Case I yields a viable theory. In this case the metric outside a star of mass $M_*$ can be modeled by that of a point-like global monopole whose mass is $M_*$ and a deficit angle $Δ= \sqrt{(2GH_0M_*)/(3c^3)}$, where $H_0$ is the Hubble rate and $G$ the Newton constant. This deficit angle can be used to test the theory since light exhibits additional bending around stars given by, $α_D\approx -πΔ/2$. This angle is independent on the distance from the star and it affects equally light and massive particles. The effect is too small to be measurable today, but should be within reach of the next generation of high resolution telescopes. Finally we note that the advancement of periastron of a planet orbiting around a star or black hole, which equals $πΔ$ per period, can be also used to test the theory.

description: Power relations are commonplace and appear ubiquitously. You encounter them in the private and in the public sphere. Everyone is involved in a variety of such relationships, mostly without being aware of it. They determine our life, set limits to our development and influence our thinking and our everyday experience. Knowledge, position, money, prestige, office and dignity, access to information, the development of networks and cliques, good looks, wealth and much more are basically only convertible currencies of power. The quest for power is an unacknowledged, yet central, motive for human action. The text illuminates a kaleidoscope of power relations that we are confronted with on a daily basis. Different examples illustrate the effect of power relations in our environment. A plausible explanation for the striving for power is discussed.

We generalize the derivative expansion, and then apply it to energy-independent and non-local potentials in a coupled-channel model. We observe that the expansion converges by comparing the scattering phase shifts computed from these potentials with the exact one. We have also found that the convergence can be improved by either varying the choice of interpolating fields or tuning the expansion scale in the generalized derivative expansion. The results will be utilized in future lattice QCD calculations, allowing for further application of the HAL QCD method.

description: The discovery of multiple stellar populations in Milky Way globular clusters (GCs) has stimulated various follow-up studies on helium-enhanced stellar populations. Here we present the evolutionary population synthesis models for the spectro-photometric evolution of simple stellar populations (SSPs) with varying initial helium abundance ($Y_{\rm ini}$). We show that $Y_{\rm ini}$ brings about {dramatic} changes in spectro-photometric properties of SSPs. Like the normal-helium SSPs, the integrated spectro-photometric evolution of helium-enhanced SSPs is also dependent on metallicity and age for a given $Y_{\rm ini}$. {We discuss the implications and prospects for the helium-enhanced populations in relation to the second-generation populations found in the Milky Way GCs.} All of the models are available at \url{http://web.yonsei.ac.kr/cosmic/data/YEPS.htm}.

description: We present a model for the origin of the extended law of star formation in which the surface density of star formation ($Σ_{\rm SFR}$) depends not only on the local surface density of the gas ($Σ_{g}$), but also on the stellar surface density ($Σ_{*}$), the velocity dispersion of the stars, and on the scaling laws of turbulence in the gas. We compare our model with the spiral, face-on galaxy NGC 628 and show that the dependence of the star formation rate on the entire set of physical quantities for both gas and stars can help explain both the observed general trends in the $Σ_{g}-Σ_{\rm SFR}$ and $Σ_{*}-Σ_{\rm SFR}$ relations, but also, and equally important, the scatter in these relations at any value of $Σ_{g}$ and $Σ_{*}$. Our results point out to the crucial role played by existing stars along with the gaseous component in setting the conditions for large scale gravitational instabilities and star formation in galactic disks.

Klischee:
"Druck- Bildstock", auch übertragen im Sinne von "Abklatsch, billige Nachahmung": Das Wort wurde als Fachausdruck der Buchdruckersprache aus frz. cliché "Abklatsch", dem substantivierten Part. Perf. von clicher "abklatschen", entlehnt. Das Verb selbst erscheint bei uns im 20. Jh. als klischieren "ein Klischee herstellen; tatenlos nachahmen". Frz. clicher ist wohl lautmalenden Ursprungs und erinnert an dt. klitschen, klatschen."

description: La présente fiche indicateur concerne l’évaluation de la contamination en polychlorobiphényles (PCB), dioxines et furanes chez les poissons. Du fait de leur persistance, bioaccumulation dans les réseaux trophiques et toxicité, les PCB et dioxines sont listés POP (Persistent Organic Pollutants) par la convention de Stockholm. Les 7 congénères majoritairement retrouvés (PCB 28, PCB 52, PCB 101, PCB 118, PCB 138, PCB 153, PCB 180) sont utilisés comme indicateurs communs par OSPAR et Barcelone. De plus, les dioxines, les furanes et les PCB de type dioxine font également partie de la liste des substances prioritaires de la Directive Cadre sur l’Eau (DCE) sous la forme d’une TEQ (Toxic Equivalent Quantity – Quantité Equivalente Toxique).
Leurs teneurs ont été déterminées dans les muscles de poissons prélevés en 2018 lors des campagnes halieutiques « Data Collection Framework (DCF) », dans le cadre du suivi des Contaminants dans les Réseaux Trophiques (CoRePh). Ces teneurs renseignent sur la contamination du plateau continental au-delà de l’emprise des masses d’eaux côtières des Sous-Régions Marines Manche – Mer du Nord (SRM MMN), Mers Celtiques (MC) et Golfe de Gascogne (GdG). Les concentrations en PCB 118 et en dioxines/composés de type dioxine (TEQ) chez les poissons sont entre 1 et 2,2 fois supérieures aux seuils environnementaux (PCB : EAC, OSPAR, 2023, TEQ : QE, 2013/39/UE) pour les SRM MMN et GdG, par conséquent, il ne peut pas être exclu que les concentrations observées en PCB 118 et dioxines, furanes et PCB de type dioxine puissent nuire aux espèces marines dans les zones évaluées (paramètres non atteints). Par ailleurs, les concentrations des 6 autres congénères de PCB sont inférieures aux seuils sur la région marine Atlantique (paramètres atteints). Au vu de ces résultats, les concentrations observées de chacun de ces 6 PCB (évaluées individuellement) ne sont pas susceptibles d’affecter les espèces marines dans les zones évaluées.
A l’échelle du plateau continental au-delà de l’emprise des masses d’eaux côtières des SRM MMN et GdG, le paramètre « concentration dans le biote - Poissons » est ainsi atteint pour les PCB 28, 52, 101, 138, 153, 180, et non atteint pour le PCB 118 et les dioxines/composés de type dioxine. Le paramètre est atteint pour l’ensemble des substances pour la MC.

description: The eShel, an off-the-shelf, fiber-fed echelle spectrograph ($R \approx 10,000$), was installed on the 1m telescope at the Wise observatory in Israel. We report the installation of the multi-order spectrograph, and describe our pipeline to extract stellar radial velocity from the obtained spectra. We also introduce a new algorithm---UNICOR, to remove radial-velocity systematics that can appear in some of the observed orders. We show that the system performance is close to the photon-noise limit for exposures with more than $10^7$ counts, with a precision that can get better than 200 m/s for F--K stars, for which the eShel spectral response is optimal. This makes the eShel at Wise a useful tool for studying spectroscopic binaries brighter than $m_V=11$. We demonstrate this capability with orbital solutions of two binaries from projects being performed at Wise.

description: Machine learning techniques are widely applied in many modern optical sky surveys, e.q. Pan-STARRS1, PTF/iPTF and Subaru/Hyper Suprime-Cam survey, to reduce human intervention for data verification. In this study, we have established a machine learning based real-bogus system to reject the false detections in the Subaru/Hyper-Suprime-Cam StrategicSurvey Program (HSC-SSP) source catalog. Therefore the HSC-SSP moving object detection pipeline can operate more effectively due to the reduction of false positives. To train the real-bogus system, we use the stationary sources as the real training set and the "flagged" data as the bogus set. The training set contains 47 features, most of which are photometric measurements and shape moments generated from the HSC image reduction pipeline (hscPipe). Our system can reach a true positive rate (tpr) ~96% with a false positive rate (fpr) ~ 1% or tpr ~99% at fpr ~5%. Therefore we conclude that the stationary sources are decent real training samples, and using photometry measurements and shape moments can reject the false positives effectively.

description: Executive summary:
 Stabilising and increasing crop yields in the face of global climate change, while safeguarding biodiversity and suppling high-quality food, feed, and biomass are a priority for Europe. A second Green Revolution in crop production is needed to meet future crop biomass and yield demands. This represents a huge challenge to all agricultural value chain players. Multiple new crop technologies including molecular markers for key traits to support modern breeding are already at Technology Readiness Levels (TRLs) 3-5, although to date, efforts have been fragmented and small scale. The CropBooster Program proposes a coordinated European Research Agenda designed to accelerate the development of improved crops in line with societal expectations. These future-proofed crops will help European agriculture transition to a sustainable climate-ready model that addresses food security concerns and meets the needs of Europe’s bioeconomy.

Ces teneurs renseignent sur la contamination du plateau continental et son rebord (têtes de canyons) au-delà de l’emprise des masses d’eaux côtières de la Sous-Région Marine Méditerranée Occidentale (SRM MO), pour les zones « Golfe du Lion » (GdL) et « Corse ».
Les concentrations en PCB 118 chez les poissons sont entre 1,2 (merlu en Corse) et 2,6 (rouget en GdL) fois supérieures aux seuils environnementaux (EAC). Les concentrations en dioxines/composés de type dioxine (TEQ) chez les poissons du Golfe du Lion sont entre 1,7 (rouget) et 1,9 (merlu) fois supérieures aux seuils environnementaux (QE, 2013/39/UE). Bien que les seuils ne soient pas dépassé au niveau de l’espèce pour le PCB 138, le score de contamination intégrant les différentes espèces poissons dépasse le seuil de 1 dans le GdL. Il ne peut donc pas être exclu que les concentrations observées en PCB 118, PCB 138 et dioxines/composés de type dioxine puissent nuire aux espèces marines dans les zones évaluées. Par ailleurs, les concentrations des 5 autres congénères de PCB sont inférieures aux seuils pour la SRM MO. Au vu de ces résultats, les concentrations observées de chacun de ces 5 PCB (évalués individuellement) ne sont pas susceptibles d’affecter les espèces marines dans les zones évaluées.
A l’échelle du plateau continental au-delà de l’emprise des masses d’eaux côtières de la SRM MO, le paramètre « concentration dans le biote - Poissons » est ainsi atteint pour les PCB 28, 52, 101, 153, et 180 pour les deux zones évaluées (GdL et Corse). De plus, il est atteint pour le PCB 138 et les dioxines/composés de type dioxine (TEQ) chez les poissons en Corse. Le paramètre n’est pas atteint pour le PCB 118 dans les deux zones évaluées, et pour le PCB 138 et les dioxines/composés de type dioxine (TEQ) chez les poissons du GdL.
Bayesian Unification of Gradient and Bandit-based Learning for Accelerated Global Optimisation

description: Bandit based optimisation has a remarkable advantage over gradient based approaches due to their global perspective, which eliminates the danger of getting stuck at local optima. However, for continuous optimisation problems or problems with a large number of actions, bandit based approaches can be hindered by slow learning. Gradient based approaches, on the other hand, navigate quickly in high-dimensional continuous spaces through local optimisation, following the gradient in fine grained steps. Yet, apart from being susceptible to local optima, these schemes are less suited for online learning due to their reliance on extensive trial-and-error before the optimum can be identified. In this paper, we propose a Bayesian approach that unifies the above two paradigms in one single framework, with the aim of combining their advantages. At the heart of our approach we find a stochastic linear approximation of the function to be optimised, where both the gradient and values of the function are explicitly captured. This allows us to learn from both noisy function and gradient observations, and predict these properties across the action space to support optimisation. We further propose an accompanying bandit driven exploration scheme that uses Bayesian credible bounds to trade off exploration against exploitation. Our empirical results demonstrate that by unifying bandit and gradient based learning, one obtains consistently improved performance across a wide spectrum of problem environments. Furthermore, even when gradient feedback is unavailable, the flexibility of our model, including gradient prediction, still allows us outperform competing approaches, although with a smaller margin. Due to the pervasiveness of bandit based optimisation, our scheme opens up for improved performance both in meta-optimisation and in applications where gradient related information is readily available.
