A few logs suffice to build (almost) all trees (l): part I

Inferring evolutionary trees is an interesting and important problem in biology that is very difficult from a computational point of view as most associated optimization problems are NP-hard. Although it is known that many methods are provably statistically consistent (i.e. the probability of recovering the correct tree converges on 1 as the sequence length increases), the actual rate of convergence for different methods has not been well understood. In a recent paper we introduced a new method for reconstructing evolutionary trees called the Dyadic Closure Method (DCM), and we showed that DCM has a very fast convergence rate. DCM runs in O(n^5 log n) time, where n is the number of sequences, so although it is polynomial it has computational requirements that are potentially too large to be of use in practice. In this paper we present another tree reconstruction method, the Witness-Antiwitness Method, or WAM. WAM is significantly faster than DCM, especially on random trees, and converges at the same rate as DCM. We also compare WAM to other methods used to reconstruct trees, including Neighbor Joining (possibly the most popular method among molecular biologists), and new methods introduced in the computer science literature.
300 mm wafer-level hybrid bonding for Cu/interlayer dielectric bonding in vacuum

Wafer bonding technology is one of the key technologies for high-density three-dimensional integration. We demonstrated 300 mm wafer-level hybrid bonding with Cu and an interlayer dielectric (ILD) layer with the design of 1 × 1 μm2 pads with 2 μm pitch. In this sequence of the bonding process, the structure of Cu bonding pads was controlled to be precisely convex to the ILD layer by chemical-mechanical polishing. Then the bonding process was performed in vacuum. Lastly, the bonded wafers were annealed at 200 °C for the postannealing process. As a result, hybrid wafer bonding with few voids was successfully accomplished.
Smart Road Surface Monitoring with Privacy Preserved Scheme for Vehicle Crowd Sensing

In the Modern years many varieties of solutions has been framed for transport infrastructure such as street view application, traffic scrutiny, shortest road path navigation and route discovery. The current requirements and most significant of transport infrastructure has been lead towards the monitoring of road surface condition. Many varieties of solutions have been generated with sensor technology in existing system. Because of this, most of the systems using sensors are getting trouble in existing method for analyzing the condition of road surface and also no awareness or warning for the people who travel for the first time. So that initially visual observe of every surface of the road for the particular areas has been analyzed for a superior solution. Observation can be done by taking site survey, street view applications and also getting suggestion from the highway engineers. Later every detail about the surface of the observed road will be updated with the help of crowd sensing and Global Positioning System (GPS) Vehicle based sensing technology frequently which provides the user-friendly transport services to the customer. In our work the intermediate server called Fog Node is proposed to update the genuine data about the surface of the road condition to the cloud server by applying the Light Weight Signcryption method. The best road condition path for the sensor based cars is to be notified when the car is nearer to the Road Side Unit (RSU) with the help of Global System for Mobile communication (GSM) and also the details will be provided for the client on demand. The implementation can be proved with our proposed method to reach the best path recover, less storage, power consumption and finding proper route discovery. Also, it will dispense on demand data for the road based customers through mobile application with privacy preserved technology.
Bombeiros militares com lombalgia crônica não apresentam desequilíbrio no torque isocinético dos músculos flexores e extensores do tronco

INTRODUCTION: Chronic nonspecific low back pain in the military firefighter is a cause of withdrawal from work and early retirement. The relationship between the torque of the flexors and extensors of the trunk - F / E ratio - is a way to measure the balance of this musculature, it has been found between 0.7 and 0.9 in asymptomatic individuals and above 1.0 in individuals with low back pain. The objective of this study was to evaluate if there is an imbalance of the trunk muscles in the military firefighter with diagnosis of chronic non-specific low back pain and to analyze the association of the peaks of isokinetic torque with physical variables such as age, weight, body mass index, manual and pain grip strength and disability. The hypothesis of the study is that there is muscle imbalance and that there would be an association of torque peaks with physical variables, pain, and disability. METHODS: Anthropometric data were collected and the subjects were evaluated for pain by Visual Analogue Scale and disability by the Roland Morris Disability Questionnaire (RMDQ). One hundred and fifteen firefighters were evaluated in the isokinetic dynamometer Biodex System 4 at 60 ° / s and at 120 ° / s with 2 sets of 5 repetitions at each speed. We analyzed peak torque and F/E ratio. RESULTS: We found the peak torque of the flexors larger than the extensors in our population and an F / E ratio of 0.72 to 0.89. There was a positive correlation between peak torque of flexors with manual grip strength and height, and negative correlation with age and BMI. There was no association of peak torque with pain or disability. DISCUSSION: In the two speeds investigated, military firefighters present F / E values within normal and non-athlete patterns, without the expected change for individuals with nonspecific chronic low back pain. This raises the need to re-discuss the approach of traditional strengthening programs for military firefighters with low back pain and a need for further studies to re-evaluate the expected parameters in other populations
Patient Safety Climate (PSC) in Outpatient Surgery Centers

We examined perceptions of safety climate from health care professionals involved in the “Systems Engineering Intervention in Outpatient Surgery - a Collaborative Community Perspective” study currently underway at the University of Wisconsin-Madison. Surveys were conducted in five outpatient surgery centers. The objectives of this study were to examine patient safety climate across various outpatient surgery centers and to address the relationship between patient safety climate and job categories, individual outpatient centers and the respondents' Quality of Working Life (QWL). Our results indicate that four safety climate scales (1) Top management commitment to patient safety, (2) General patent safety climate, (3) Employee commitment to patient safety, and (4) Change in patient safety can be created from the 12-item questionnaire and they may be a useful measure of an outpatient surgery center's patient safety climate. The four patient safety climate scales are also significantly associated with the outpatient surgery centers employees' QWL.

Recovering node parameters and topologies of uncertain non‐linearly coupled complex networks

Node dynamics and network topologies play vital roles in determining dynamical behaviours and features of complex networks. Thus it is of great theoretical significance and practical value to identify the node parameters and topologies of uncertain complex networks. This study presents adaptive anticipatory synchronisation-based approaches to identify the unknown node parameters and topologies of uncertain non-linearly coupled complex networks perturbed by stochastic noise. Moreover, during the identification process, the authors proposed scheme guarantees anticipatory synchronisation between the uncertain drive and constructed response network simultaneously. In particular, their methods can be used to recover node parameters and topologies of complex networks in several special cases, such as cases without node delay or coupling delay. Furthermore, numerical simulations are provided to verify the applicability and effectiveness of their methods for recovering node parameters and topologies of uncertain non-linearly coupled complex networks.
A Comparative Study on Credit Card Default Risk Predictive Model

The risk analysis of credit card defaulters is a critical procedure in the banking sector to classify the card applicants. Banks perform credit score check to make decisions on applications and to set credit limit accordingly. With the increase in the amount of data and advances in data analytics, the approval process can now be automated for quicker processing of applications. This study aims to provide solutions to improve the risk management strategy among financial institutions using predictive analytics. A real-world dataset obtained from a bank in Taiwan were used to perform the analysis in this project. Four data mining algorithms including Decision Tree, Logistic Regression, Random Forest and Neural Network were constructed with the cleaned dataset. Results revealed that Neural Network is the best performing model with an 82% predictive accuracy of credit card defaulters.

The concept of representative crack elements for phase‐field fracture: Anisotropic elasticity and thermo‐elasticity

The realistic representation of material degradation at a fully evolved crack is still one of the main challenges of the phase‐field method for fracture. An approach with realistic degradation behavior is only available for isotropic elasticity in the small deformation framework. In this paper, a variational framework is presented for the standard phase‐field formulation, which allows to derive the kinematically consistent material degradation. For this purpose, the concept of representative crack elements (RCE) is introduced to analyze the fully degraded material state. The realistic material degradation is further tested using the self‐consistency condition, where the behavior of the phase‐field model is compared to a discrete crack model. The framework is applied to isotropic elasticity, anisotropic elasticity and thermo‐elasticity, but not restricted to these constitutive formulations.
Population genetics of lepidopteran (noctuidae) collected on transgenic and non-transgenic maize in Mexico

Allele frequency of the resistance of the gene Onb3GalT5 to Cry proteins was analyzed in insect populations (Helicoverpa zea and Heliothis virescens), collected from maize transgenic and non-transgenic plants. The genetic parameters estimated in these populations were allele and genotype frequency, genetic balance and Wright statistics (Fis, Fit and Fst). Statistical analyses were performed using the package Genepop (4.0.10). Results showed that from the DNA of H. virescens, collected on non-transgenic maize, a higher number of bands were amplified in a range from 250 bp to 600 bp. In contrast, the bands amplified from insects collected on transgenic maize were in the range of 250 bp-500 bp, being the 400 bp band in both cases the most frequent, while in the DNA of Helicoverpa zea, collected on transgenic maize, three bands (350 bp, 400 bp and 450 bp) were amplified, and in H. zea, collected on non-transgenic maize, only two bands (350 bp and 400 bp) were observed. Genetic diversity in insect populations was higher than within these same populations.
Physical Modelling and the Associated Acoustic Behaviour of Trumpets and Trombones

Accurately modelling the production of realistic musical notes in brass instruments is no easy task. Compared to woodwind instruments, brass instruments are considerably longer and constructed with bends, valves or coils, a mouthpiece with a cup rather than a reed or double-reed, as well as a large flare. Mathematically, this means that the sound wave propagation through the instrument could exhibit various nonlinear behaviours that are not examined within the field of linear acoustics. In this thesis, we attempt to accurately model the timbre of musical notes produced on the trumpet and trombone and study the associated acoustic behaviours of both instruments. To accomplish this, we investigate the relevance of the interaction between the player and instrument to ensure the problem is computationally reasonable, as we need to decipher what aspects and parameters can be neglected, and which are essential to consider. This was done through a series of physical experiments and numerical studies, which also provided verification of previous claims and findings published in the literature. Ultimately, we determined there are factors more essential to incorporate over modelling vibroacoustic and thermoviscous effects. We therefore focus on these components and model the nonlinear wave propagation through the instruments in the time-domain using the compressible Euler equations, and numerically solve the system via the discontinuous Galerkin method. Several musical notes played at various dynamic levels are simulated. The numerical solutions are compared against the measured data to evaluate how well the timbre of the different musical tones can be recreated. Although several simplifying assumptions were made, we found that our model produces the most accurate results compared to previous findings. Furthermore, to our knowledge, we are the first to numerically reproduce (from real data) the production of shock waves in the trombone, thereby theoretically and numerically verifying the experimental work published by Hirschberg et al. in 1996 (https://doi.org/10.1121/1.414698).
A nonuniform metasurface loaded circularly polarized differentially-fed antenna

ABSTRACT This paper reports a novel differentially driven circularly polarized metasurface-based antenna with symmetrical and unidirectional radiation pattern. The introduction of metasurface could generate an additional resonance. The location of lower resonant frequency could be tuned independently by varying the length of cross gap in the ground plane while the higher resonant frequency is insensitive to this change. In addition, it is also proved that the circularly polarized performance could be better using the nonuniform metasurface than the uniform one. Furthermore, an antenna prototype has been fabricated to experimentally validate the principle and design approach. The measurements agree reasonably with the simulated ones.
Robust parameter estimation for constrained time-delay systems with inexact measurements

In this paper, we consider estimation problems involving constrained nonlinear systems with the unknown time-delays and unknown system parameters. These unknown quantities are to be estimated such that a least-squares error function between the system output and a set of noisy measurements is minimized subject to the characteristic time constraints specifying the restrictions. We first present the classical estimation formulation, where the expectation of the error function is regarded as the cost function. Then, in order to obtain robust estimates against the noises in measurements, we propose a robust estimation formulation, in which the cost function is the variance of the error function and an additional constraint indicates an allowable sacrifice from the optimal expectation value of the classical estimation problem. For these two estimation problems, we derive the gradients of the corresponding cost and constraint functions with respect to time-delays and system parameters by solving some auxiliary time-delay systems backward in time. On this basis, we develop gradient-based optimization algorithms to determine the optimal time-delays and system parameters. Finally, we consider two example problems, including a parameter estimation problem in microbial batch fermentation process, to illustrate the effectiveness and applicability of our proposed algorithms.
Notable effect of the subgrid-scale stress anisotropy on mean-velocity prediction through budget of the grid-scale Reynolds-shear stress

In large eddy simulation (LES), the mean-velocity distribution in wall turbulence depends strongly on the distribution of the ensemble-averaged Reynolds (Re) shear stress, which consists of two parts: the resolved grid-scale (GS) and unresolved subgrid-scale (SGS) components. As the grid resolution becomes coarser, the GS component decreases and thus the SGS component must increase to compensate for this. The GS decrease is originally caused by filtering, through which the power spectrum is cut off mainly in the high-wavenumber region. Therefore, the SGS model has been discussed mostly in terms of the energy transfer between the GS and SGS components. Recently, however, some studies have found that the SGS-stress anisotropy directly influences instantaneous GS vortex motions. This also means that the SGS stress may have a large effect on the ensemble-averaged GS Re stress because the instantaneous fluctuation of the SGS stress correlates with that of the velocity gradient in the GS budget. In this study, we investigate in detail the effect of the SGS stress on predicting the resolved GS Re shear stress through its budget. For this purpose, we perform a priori tests with highly resolved LES data of a plane channel flow. The knowledge obtained is then confirmed by a posteriori tests for various grid resolutions and Reynolds numbers. It is found that the SGS-stress anisotropy is very important for providing a reasonable trend of the GS Re shear stress, leading to more accurate prediction of the mean velocity for coarse-grid resolutions.In large eddy simulation (LES), the mean-velocity distribution in wall turbulence depends strongly on the distribution of the ensemble-averaged Reynolds (Re) shear stress, which consists of two parts: the resolved grid-scale (GS) and unresolved subgrid-scale (SGS) components.

Exploring a vocabulary test and a judgment task as diagnoses of early and late bilinguals' L2 proficiency

Este estudo psicolinguistico investigou a adequacao de uma medida de tamanho de vocabulario o Vocabulary Levels Test (VLT) como preditor da capacidade de acesso as representacoes gramaticais de falantes de portugues brasileiro e ingles, bem como de falantes de espanhol como lingua de heranca (HL) no momento em que estao usando sua lingua nao-dominante. Considerando o cenario com dois tipos de bilingues (falantes de L2 e falantes de HL), dois tipos de conhecimento (implicito e explicito) e dois tipos de medidas de proficiencia (tamanho de vocabulario e julgamento de sentenca), nos conduzimos um estudo exploratorio desenhado como dois experimentos. No primeiro experimento, comparamos o desempenho dos participantes no VLT (versao em ingles), um teste de habilidades gerais (Oxford Placement Test OPT) e uma tarefa de julgamento temporalizado (SAJ) em ingles, na qual um teto temporal de 8 segundos foi estabelecido para cada julgamento. No Segundo experimento, nos comparamos o desempenho dos participantes no VLT (versao em espanhol), na versao em espanhol do teste de habilidades gerais (SPT), a SAJ em espanhol, na qual um teto temporal de 6 segundos foi estabelecido para cada julgamento e um teste de auto-avaliacao sobre habilidades linguisticas. Alem disso, no segundo experimento, um questionario de historico bilingue (o BHQ) foi usado na operacionalizacao da classificacao dos HL pelo uso/dominância linguistica. Em ambos os experimentos, os nossos estimulos da SAJ foram compostas de 56 sentencas, 16 delas continham violacoes gramaticais. Havia dois tipos de violacoes de sentencas: violacoes de realizacao de estrutura argumental envolvendo verbos inergativos transitivizados e violacoes morfosintaticas explicitas envolvendo dependencias de longa distância (movimento WH) e concordância sujeito-verbo. Em ambos os experimentos, o VLT, o OPT / SPT e as tarefas SAJ foram submetidos a curva ROC (Receiver Operating Characteristic) para a avaliacao da sensibilidade e especificidade como diagnostico adequado de proficiencia linguistica. Os resultados para ambos os experimentos mostram que somente os participantes que foram classificados como de alta proficiencia no VLT e OPT / SPT foram capazes de detectar violacoes gramaticais. Nos interpretamos os resultados como indicAdores de que a medida do tamanho do vocabulario e um preditor tanto de fluencia em acesso lexical quanto de fluencia no acesso ao conhecimento gramatical de falantes de L2 e HL. Alem disso, analises com a curva ROC nos dois experimentos revelaram que o VLT e a SAJ sao instrumentos adequados para o diagnostico de proficiencia da lingua, uma vez que sao capazes de diferenciar dois grupos de proficiencia.
