 Pterolonche douxi Varenne & Nel 2018: 8, figs. 13–14, 16–18.
 Examined material. Holotype Ƌ: France, Alpes-de-Haute-Provence, Riez, Mauras, 640 m, uv, 10.VI.2017, Yves Doux leg., genitalia slide JN n°31546 (RCJN) [TLMF].
BOLD Specimen ID TLMF 27071; BOLD Sequence ID LEASV319-19.
BIN: BOLD:AAD3841
 Identity: Pterolonche douxi Varenne & Nel, 2018
 Remarks. Pterolonche douxi was described from a male holotype and three female paratypes and distinguished from the morphologically similar P. inspersa Staudinger, 1859, originally described from Spain (Varenne & Nel 2018). The successfully sequenced holotype of P. douxi shows a considerable divergence in the DNA barcode of ca. 3% which supports the separate species status of both taxa.

description: Graphene hydrophobic coatings paved the way towards a new generation of optoelectronic and fluidic devices. Nevertheless, such hydrophobic thin films rely only on graphene non-polar surface, rather than taking advantage of its surface roughness. Furthermore, graphene is typically not self-standing. Differently, carbon aerogels have high porosity, large effective surface area due to their surface roughness, and very low mass density, which make them a promising candidate as a super-hydrophobic material for novel technological applications. However, despite a few works reporting the general super-hydrophobic and lipophilic behavior of the carbon aerogels, a detailed characterization of their wetting properties is still missing, to date. Here, the wetting properties of graphene aerogels are demonstrated in detail. Without any chemical functionalization or patterning of their surface, the samples exhibit a super-lipophilic state and a stationary super-hydrophobic state with a contact angle up to $150\pm15^°$ and low contact angle hysteresis $\approx15^°$, owing to the fakir effect. In addition, the adhesion force of the graphene aerogels in contact with the water droplets and their surface tension are evaluated. For instance, the unique wettability and enhanced liquid absorption of the graphene aerogels can be exploited for reducing contamination from oil spills and chemical leakage accidents.

description: Twenty seven corn cultivars from the PCCMCA (Central America Cooperative Improvement Program) test were planted at two dates during 1982-83 at Isabela, Puerto Rico. The combined analysis of variance showed that there were significant differences between planting dates for grain yield, midbloom, leaf area index and rust reaction. Differences among cultivars were observed for all traits except test weight. Cultivar TICO V-6 from Costa Rica produced the highest grain yield (over 6 tons ha-1) at both planting dates.

Lattice Matrix Elements and CP Violation in B and K Physics: Status and Outlook
Creators: name: Soni, Amarjit
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Status of lattice calculations of hadron matrix elements along with CP violation in B and in K systems is reviewed. Lattice has provided useful input which, in conjunction with experimenatl data, leads to the conclusion that CP-odd phase in the CKM matrix plays the dominant role in the observed asymmetry in $B \to ψK_s$. It is now quite likely that any beyond the SM, CP-odd, phase will cause only small deviations in B-physics. Search for the effects of the new phase(s) will consequently require very large data samples as well as very precise theoretical predictions. Clean determination of {\it all} the angles of the unitarity triangle therefore becomes essential. In this regard $B \to K D^0$ processes play a unique role. Regarding K-decays, remarkable progress made by theory with regard to maintenance of chiral symmetry on the lattice is briefly discussed. First application already provide quantitaive information on $B_K$ and the $ΔI=1/2$ rule. The enhancement in $Re A_0$ appears to arise solely from tree operators, esp. $Q_2$; penguin contribution to $Re A_0$ appears to be very small. However, improved calculations are necessary for $ε^'/epsilon$ as there the contributions of QCD penguins and electroweak penguins largely seem to cancel. There are good reasons, though, to believe that these cancellations will not survive improvements that are now underway. Importance of determining the unitarity triangle purely from K-decays is also emphasized.

description: A Type Ia supernova explosion likely begins as a nuclear runaway near the center of a carbon-oxygen white dwarf. The outward propagating flame is unstable to the Landau-Darrieus, Rayleigh-Taylor, and Kelvin-Helmholtz instabilities, which serve to accelerate it to a large fraction of the speed of sound. We investigate the Rayleigh-Taylor unstable flame at the transition from the flamelet regime to the distributed-burning regime, around densities of $10^7$ g/cc, through detailed, fully resolved simulations. A low Mach number, adaptive mesh hydrodynamics code is used to achieve the necessary resolution and long time scales. As the density is varied, we see a fundamental change in the character of the burning--at the low end of the density range the Rayleigh-Taylor instability dominates the burning, whereas at the high end the burning suppresses the instability. In all cases, significant acceleration of the flame is observed, limited only by the size of the domain we are able to study. We discuss the implications of these results on the potential for a deflagration to detonation transition.

description: The objective of this study was to model seasonal behavior of broiler price in Iran that can be used to forecast the monthly broiler prices. In this context, the periodic autoregressive (PAR), the seasonal integrated models, and the Box-Jenkins (SARIMA) models were used as the primary nominates for the forecasting model. It was shown that the PAR (q) model could not be considered as an appropriate method for modeling seasonal behavior of the broiler price. Results of seasonal unit root test indicated that the monthly prices of broiler follow a non-stationary stochastic seasonal process. Accordingly, the regression-based model is an appropriate modeling framework. While SARIMA is an alternative modeling approach, the RMSE of forecasting error suggested the superiority of the regression- based model over the SARIMA model. Therefore, the estimated parameters of the regression-based model can be used to predict the monthly prices of broiler in Iran.

description: We present new results from high sensitivity GMRT observations of PSR B0826-34. We provide a model to explain the observed subpulse drift properties of this pulsar, including the apparent reversals of the drift direction. In this model, PSR B0826-34 is close to being an aligned rotator. We solve for the emission geometry of this pulsar and show that the angle between the rotation and the magnetic axes is less than 5 deg. We see evidence for as many as 6 to 7 drifting bands in the main pulse at 318 MHz, which are part of a circulating system of about 15 spark-associated subpulse emission beams. We provide quantitative treatments of the aliasing problem and various effects of geometry. The observed drift rate is an aliased version of the true drift rate, such that a subpulse drifts to the location of the adjacent subpulse (or a multiple thereof) in about one pulsar period. We show that small variations, of the order of 3-8%, in the mean drift rate are then enough to explain the apparent reversals of drift direction. We find the mean circulation time of the drift pattern to be significantly longer than the predictions of the original RS75 model and propose an explanation for this, based on modified models with temperature regulated partial ion flow in the polar vacuum gap. From the variation of the mean subpulse separation across the main pulse window, we show that the spark pattern is not centred around the dipole axis, but around a point much closer (within a degree or so) to the rotation axis -- we discuss the implication of this.

description: The main purpose of this paper was to introduce an efficient algorithm for fault identification in fruits images. First, input image was de-noised using the combination of Block Matching and 3D filtering (BM3D) and Principle Component Analysis (PCA) model. Afterward, in order to reduce the size of images and increase the execution speed, refined Discrete Cosine Transform (DCT) algorithm was utilized. Finally, for segmentation, fuzzy clustering algorithm with spatial information was applied on the compressed image. Implementation results in MATLAB environment and based on the gathered data showed that the proposed algorithm contains a good capability in de-noising. Also, in the proposed method, identification accuracy of faulty regions in fruit was higher than other methods. The major advantage of the proposed method was its high speed which makes it appropriate for real time applications.

description: (abridged) Spectral energy distributions (SEDs) were constructed for a sample of 477 classical cepheids (CCs). The SEDs were fitted with a dust radiative transfer code. Four stars showed a large mid- or far-infrared excess and the fitting then included a dust component. These comprise the well-known case of RS Pup, and three stars that are (likely) Type-II cepheids (T2Cs), AU Peg, QQ Per, and FQ Lac. The remainder of the sample was fitted with a stellar photosphere to derive the best-fitting luminosity and effective temperature. Distance and reddening were taken from the literature. The stars were plotted in a Hertzsprung-Russell diagram and compared to evolutionary tracks for cepheids and theoretical instability strips. For the large majority of stars, the position in the HRD is consistent with the instability strip for a CC or T2C. About 5% of the stars are outliers in the sense that they are much hotter or cooler than expected. A comparison to effective temperatures derived from spectroscopy suggests in some cases that the photometrically derived temperature is not correct and that this is likely linked to an incorrectly adopted reddening. In this work the presence of a small NIR excess, as has been proposed in the literature for a few well-known cepheids, is investigated. Firstly, this was done by using a sample of about a dozen stars for which a mid-infrared spectrum is available. Secondly, the SEDs of all stars were fitted with a dust model to see if a statistically significant better fit could be obtained. The results were compared to recent work. Eight new candidates for exhibiting a NIR excess are proposed, solely based on the photometric SEDs. Obtaining mid-infrared spectra would be needed to confirm this excess. Finally, period-bolometric luminosity and period-radius relations are presented for samples of over 370 fundamental-mode CCs.

description: The purpose of the present study was to analyze the effective components of educational transformation in agricultural higher education system in Iran by a mixed study method. The statistical population includes all faculty members (N=361) teaching in agricultural college of Tehran, Tarbiat Modares and Shiraz University, and a sample of 186 faculty members (n=186) were selected by stratified random sampling method and finally 166 questionnaires were returned and analyzed. Data collection in this research was done in two general sections. Section one was a meta-synthesis method. In this method, effective components of educational transformation were identified according to investigation objectives, method of sampling, methodology, content analysis, and research results of 25 selected studies. The results of this analysis identified five main factors influencing educational transformation. These components included learning, education and teaching, competence, quality of education, and leadership. Section two was done in order to examine the hypotheses by using Structural Equation Modeling (SEM). The Results of this section showed that new learning models, leadership styles and educational competence had significant effects on educational transformation.

description: Combinatorial vector fields on simplicial complexes as introduced by Robin Forman have found numerous and varied applications in recent years. Yet, their relationship to classical dynamical systems has been less clear. In recent work it was shown that for every combinatorial vector field on a finite simplicial complex one can construct a multivalued discrete-time dynamical system on the underlying polytope X which exhibits the same dynamics as the combinatorial flow in the sense of Conley index theory. However, Forman's original description of combinatorial flows appears to have been motivated more directly by the concept of flows, i.e., continuous-time dynamical systems. In this paper, it is shown that one can construct a semiflow on X which exhibits the same dynamics as the underlying combinatorial vector field. The equivalence of the dynamical behavior is established in the sense of Conley-Morse graphs and uses a tiling of the topological space X which makes it possible to directly construct isolating blocks for all involved isolated invariant sets based purely on the combinatorial information.

title: The natural decline of potato cyst nematodes in the absence of a host crop and their movement by cultivation operations
Creators: name: Haley, Alasdair Brian
Publisher: name: The Open University
Year: 2004

description: This thesis has investigated the variation in PCN population density declines in the absence of a host crop and, the movement of PCN by cultivation operations in a potato rotation. The use of crop rotation as a management strategy for the control of potato cyst nematodes (PCN) is dependent on the natural decline rate of PCN. Any substantial variation among PCN populations will influence the adequacy and duration of crop rotation. Two experiments were undertaken to assess the extent of variation in PCN decline. Experiment 1 consisted of the annual sampling of semi-permanent field test stations to monitor the population decline in five infested fields, over four years. Large variations within the PCN population densities were found over the duration of the experiment, these included apparent increases in population density. These increases were not found for the controls in the field boundaries. The observed variations were probably due to the net movement of cysts in and around the stations as a result of soil movement by cultivation, as identified in further studies. Experiment 2 consisted of 45 plunge pits with soil from different PCN infested fields. The plunge pits were sampled at four monthly intervals, for twenty months. The range of decline was 11 to 69 % per annum. The variation in decline rates between the populations could not be accounted for by differences between G. pallida and G. rostochiensis populations or completely by soil type. This suggested that decline information was required on a site-specific basis and that sampling within a field is not reliable if cultivations are carried out between sampling dates.

Further studies determined that PCN cysts are moved by cultivation operations. With the exception of the bed-former, all cultivations investigated were found to result in the movement of PCN. The range of movement by a cultivation operation was from within 1 m up to 5 m. The cultivation operation employed and its purpose determine the direction and extent of cyst movement.

description: The main objective of the present work was to study the factors affecting the deployment of knowledge management in Agriculture Bank of Qom Province. It was a causative- relational study in terms of data collection. Also, it was a field study, non-experimental in terms of variables control. Sample size was estimated by Morgan table and the data were collected by a questionnaire. The statistical population included manager, experts and assistants of Agriculture Bank in Qom Province including 250 people. Sample size was calculated (n = 152) by Morgan table. The reliability was estimated by a pretest with 20 questionnaires filled out by a statistical population similar the studied one. The validity was confirmed by experts whose advice was taken care of about modifying or replacing some questions. Finally, Cronbach's alpha was estimated for the questionnaire to be 0.81. To achieve research objectives, the descriptive statistics of frequency, mean, variance, and standard deviation and the inferential tests of correlation and multiple regressions were conducted by SPSS Statistical Software Package. Results revealed the significant relationship of knowledge management deployment with organization culture, knowledge sources, organization memory, and information technology at the one percent level with modified determination coefficient of 0.632. In other words, 63.2% of the variation of the dependent variable was accounted by independent variables (organization culture, knowledge sources, organization memory, and information technology)

description: Clustering is a widely used technique with a long and rich history in a variety of areas. However, most existing algorithms do not scale well to large datasets, or are missing theoretical guarantees of convergence. This paper introduces a provably robust clustering algorithm based on loss minimization that performs well on Gaussian mixture models with outliers. It provides theoretical guarantees that the algorithm obtains high accuracy with high probability under certain assumptions. Moreover, it can also be used as an initialization strategy for $k$-means clustering. Experiments on real-world large-scale datasets demonstrate the effectiveness of the algorithm when clustering a large number of clusters, and a $k$-means algorithm initialized by the algorithm outperforms many of the classic clustering methods in both speed and accuracy, while scaling well to large datasets such as ImageNet.

description: Even though it may seem that information floats on its own throughout the Internet, in reality someone must make policies and financial decisions to gather and organize data and prepare it for retrieval at the appropriate time. It must be stored in various formats in information hubs. These information hubs are essential components of the Internet, itself an essential component of socioeconomic development. But are these information hubs acknowledged in international development planning in the Information Age? This paper discusses information centers – libraries, archives and museums - in the context of coordinated global planning for socioeconomic development and offers a metric by which information centers may be correlated to a country’s social and economic advancement. It concludes with reflections about information components of the United Nations (UN) 2030 Sustainable Development Goals and the needs to gather data and expand information centers in order to achieve sustainable development.

description: We show that the projected Gross-Pitaevskii equation (PGPE) can be mapped exactly onto Hamilton's equations of motion for classical position and momentum variables. Making use of this mapping, we adapt techniques developed in statistical mechanics to calculate the temperature and chemical potential of a classical Bose field in the microcanonical ensemble. We apply the method to simulations of the PGPE, which can be used to represent the highly occupied modes of Bose condensed gases at finite temperature. The method is rigorous, valid beyond the realms of perturbation theory, and agrees with an earlier method of temperature measurement for the same system. Using this method we show that the critical temperature for condensation in a homogeneous Bose gas on a lattice with a UV cutoff increases with the interaction strength. We discuss how to determine the temperature shift for the Bose gas in the continuum limit using this type of calculation, and obtain a result in agreement with more sophisticated Monte Carlo simulations. We also consider the behaviour of the specific heat.

Therefore, soil samples were collected from five land use types including road construction, cultivated area, channel bank, pasture and forest land and soil organic carbon concentration and bulk density were measured in the samples and SOCS were calculated. The results showed that the forest road construction reduce SOCS. SOC stock was greatest in the forest land use and the total SOC stock under different land uses varied in order forest, pasture, cultivate, channel bank and road construction with 143, 136, 128, 36 and 29 Mg ha −1 , respectively (p< 0.001). Therefore, these results can be useful as a scientific basis for selecting the proper soil erosion control methods as a simple and low-cost approach to mitigate the SOC loss.

description: This paper focuses on the amount of diesel consumption as one of the non-renewable energy sources consumed by the agricultural machinery and water pumps in wheat and corn farms in Dire County, Kermanshah Province, Iran. The population of the study was determined by Bartlett et al . (2001) ’stable. Stratified random sampling method and census was used for the selection of respondents. The sample was composed of 247 wheat growers, 235 corn growers, and 57 tractor drivers selected by Bartlett et al .(2001) ’stable. Combine drivers as well as farm irrigation diesel owners were selected by census (n=15, n=48, respectively). The data collection tool was a questionnaire and the data were analyzed by SPSS software package. The findings revealed that in wheat farms, soil preparation had the highest consumption of diesel by 49% and in corn farms inter culturing had the highest diesel consumption by 38%. Moreover, the amount of diesel consumed in 3600 ha wheat and a corn farm in Dire County was 403,852.6 lit/year equivalent to 15,346,399 MJ. Burning this amount of diesel produces about 1, 058,094 kg CO 2 /year. Overall, farm machinery, water pumping and irrigation for two major crops in the county are extremely reliant on nonrenewable fossil fuel resulting in large amount of CO 2 emission. Hence, an aggressive and innovative policy is required to restructure and redesign energy system in agriculture sector at national and local levels. Finally, it seems that paradigm shift to sustainable agriculture and development of clean and renewable energy in Iran's agricultural sector is unavoidable.

description: This study examined the effects of climate change on food expenditure in rural household of Iran. Food expenditure is investigated as a function of average income of rural house- holds, retail food price index and food expenditure for rural households, agricultural sown area and climate change. Here, the Stata11 software is used and data are from 26 provinces of the country for 10 years. Precipitation, temperature and relative humidity are considered as indicators for climate variables. The results indicated a positive and significant effect of average income of rural households, retail food prices, food expenditure of rural households with a lag and precipitation on the food expenditure of rural households. Agricultural sown area and relative humidity had no effect on the food expenditure of rural households and temperature had a significant and negative effect on the food expenditure of rural households. In the end, due to the impact that each of these variables explicitly have on food expenditure of rural households and implicitly on food security of rural households, suggestions for maintaining and improving food security of rural households is presented.

description: Even though it may seem that information floats on its own throughout the Internet, in reality someone must make policies and financial decisions to gather and organize data and prepare it for retrieval at the appropriate time. It must be stored in various formats in information hubs. These information hubs are essential components of the Internet, itself an essential component of socioeconomic development. But are these information hubs acknowledged in international development planning in the Information Age? This paper discusses information centers – libraries, archives and museums - in the context of coordinated global planning for socioeconomic development and offers a metric by which information centers may be correlated to a country’s social and economic advancement. It concludes with reflections about information components of the United Nations (UN) 2030 Sustainable Development Goals and the needs to gather data and expand information centers in order to achieve sustainable development.

description: Safety is a top priority for civil aviation. New anomaly detection methods, primarily clustering methods, have been developed to monitor pilot operations and detect any risks from such flight data. However, all existing anomaly detection methods are offlline learning - the models are trained once using historical data and used for all future predictions. In practice, new flight data are accumulated continuously and analyzed every month at airlines. Clustering such dynamically growing data is challenging for an offlline method because it is memory and time intensive to re-train the model every time new data come in. If the model is not re-trained, false alarms or missed detections may increase since the model cannot reflect changes in data patterns. To address this problem, we propose a novel incremental anomaly detection method based on Gaussian Mixture Model (GMM) to identify common patterns and detect outliers in flight operations from digital flight data. It is a probabilistic clustering model of flight operations that can incrementally update its clusters based on new data rather than to re-cluster all data from scratch. It trains an initial GMM model based on historical offlline data. Then, it continuously adapts to new incoming data points via an expectation-maximization (EM) algorithm. To track changes in flight operation patterns, only model parameters need to be saved. The proposed method was tested on three sets of simulation data and two sets of real-world flight data. Compared with the traditional offline GMM method, the proposed method can generate similar clustering results with significantly reduced processing time (57 % - 99 % time reduction in testing sets) and memory usage (91 % - 95 % memory usage reduction in testing sets). Preliminary results indicate that the incremental learning scheme is effective in dealing with dynamically growing data in flight data analytics.

description: A generalization of the Gibbs entropy postulate is proposed based on the BBGKY hierarchy as the nonequilibrium entropy for a system of N interacting particles. This entropy satisfies the basic principles of thermodynamics in the sense that it reaches its maximum at equilibrium and is coherent with the second law. By using a generalization of the Liouville equation describing the evolution of the distribution vector, it is demonstrated that the entropy production is a non-negative quantity. Moreover, following the procedure of non-equilibrium thermodynamics a transport matrix is introduced and a microscopic expression for this is derived. This framework allows one to perform the thermodynamic analysis of non-equilibrium steady states which, as proven here, constitute the states of minimum entropy production when one considers small departures from stationarity.

 Syncopacma cottiennella Nel 2012: 102, figs. 1–4.
 Examined material. Holotype Ƌ: France, Bauchas, col de Montgenèvre, 1850 m, Hautes-Alpes, 26.VII.2011, J. Nel leg., genitalia slide JN n°25656 (RCJN) [TLMF].
BOLD Specimen ID TLMF 28238; BOLD Sequence ID PALEA228-20.
BIN: BOLD:AEC2352
 Identity: Aproaerema cottiennella (Nel, 2012)
 Remarks. Syncopacma cottiennela was described from a male holotype and a female paratype (Nel 2012) and separated from several externally similar species by characters of the male genitalia. The DNA barcode sequence of the holotype was already published by Huemer et al. (2020) and clearly differs from all other European Aproaerema (a senior synonym of Syncopacma), thus supporting a separate species.

description: This paper presents Contextual Fibre Growth (ConFiG), an approach to generate white matter numerical phantoms by mimicking natural fibre genesis. ConFiG grows fibres one-by-one, following simple rules motivated by real axonal guidance mechanisms. These simple rules enable ConFiG to generate phantoms with tuneable microstructural features by growing fibres while attempting to meet morphological targets such as user-specified density and orientation distribution. We compare ConFiG to the state-of-the-art approach based on packing fibres together by generating phantoms in a range of fibre configurations including crossing fibre bundles and orientation dispersion. Results demonstrate that ConFiG produces phantoms with up to 20% higher densities than the state-of-the-art, particularly in complex configurations with crossing fibres. We additionally show that the microstructural morphology of ConFiG phantoms is comparable to real tissue, producing diameter and orientation distributions close to electron microscopy estimates from real tissue as well as capturing complex fibre cross sections. Signals simulated from ConFiG phantoms match real diffusion MRI data well, showing that ConFiG phantoms can be used to generate realistic diffusion MRI data. This demonstrates the feasibility of ConFiG to generate realistic synthetic diffusion MRI data for developing and validating microstructure modelling approaches.

description: The stability of the $n=m=1$ alpha-fishbone kinetic-MHD mode on the ITER 15 MA baseline scenario \cite{ITERB} is analyzed using the nonlinear hybrid Kinetic-MHD code XTOR-K. Quantitative agreement is found between the complex frequencies $ω+ iγ$ computed with the linear model in \cite{Brochard2018} and XTOR-K's linear simulations. Identical precessional resonance positions in phase space are also found between the linear model and XTOR-K. Linear hybrid simulations performed with XTOR-K on the ITER 15 MA scenario reveal that this configuration is likely to be unstable against the alpha fishbone mode. The fishbone thresholds for kinetic-MHD equilibria with flat q profiles with on-axis safety factor just below unity lies between $β_{α,thres}/β_{tot} = 6-10\%$, whereas the expected beta ratio on ITER is $β_α/β_{tot} = 15-20\%$ \cite{ITERB}.

description: This paper presents a novel approach for explainability in financial analysis by deriving financially-explainable statistical relationships through aspect-based sentiment analysis, Pearson correlation, Granger causality & uncertainty coefficient. The proposed methodology involves constructing an aspect list from financial literature and applying aspect-based sentiment analysis on social media text to compute sentiment scores for each aspect. Pearson correlation is then applied to uncover financially explainable relationships between aspect sentiment scores and stock prices. Findings for derived relationships are made robust by applying Granger causality to determine the forecasting ability of each aspect sentiment score for stock prices. Finally, an added layer of interpretability is added by evaluating uncertainty coefficient scores between aspect sentiment scores and stock prices. This allows us to determine the aspects whose sentiment scores are most statistically significant for stock prices. Relative to other methods, our approach provides a more informative and accurate understanding of the relationship between sentiment analysis and stock prices. Specifically, this methodology enables an interpretation of the statistical relationship between aspect-based sentiment scores and stock prices, which offers explainability to AI-driven financial decision-making.

description: Population studies of the orbital characteristics of exoplanets in multi-planet systems have highlighted the existence of an anticorrelation between the average orbital eccentricity of planets and the number of planets of their host system, that is, its multiplicity. This effect was proposed to reflect the varying levels of violence in the dynamical evolution of planetary systems. Previous work suggested that the relative violence of the dynamical evolution of planetary systems with similar orbital architectures can be compared through the computation of their angular momentum deficit (AMD). We investigated the possibility of using a more general metric to perform analogous comparisons between planetary systems with different orbital architectures. We considered a modified version of the AMD, the normalized angular momentum deficit (NAMD), and used it to study a sample of 99 multi-planet systems containing both the currently best-characterized extrasolar systems and the solar system, that is, planetary systems with both compact and wide orbital architectures. We verified that the NAMD allows us to compare the violence of the dynamical histories of multi-planet systems with different orbital architectures. We identified an anticorrelation between the NAMD and the multiplicity of the planetary systems, of which the previously observed eccentricity-multiplicity anticorrelation is a reflection. Our results seem to indicate that phases of dynamical instabilities and chaotic evolution are not uncommon among planetary systems. They also suggest that the efficiency of the planetary formation process in producing high-multiplicity systems is likely to be higher than that suggested by their currently known population.
