M -Lump Solution, Semirational Solution, and Self-Consistent Source Extension of a Novel ð 2 + 1 Þ -Dimensional KdV Equation

In this paper, we derive the M -lump solution in terms of Matsuno determinant for the combined KP3 and KP4 (cKP3-4) equation by applying the double-sum identities for determinant and investigate the dynamical behaviors of 1- and 2-lump solutions. In addition, we derive the Grammian solution for the cKP3-4 equation and construct the semirational solutions from the Grammian solution. Through the asymptotic analysis, we show that the semirational solutions describe fusion and ﬁ ssion of lumps and line solitons and rogue lump phenomena. Furthermore, we construct the cKP3-4 equation with self-consistent sources via the source generation procedure and present its Grammian and Wronskian solution.
Improving Ultrasound Image Classification with Local Texture Quantisation

Ultrasound image classification is important for disease diagnosis. It is more challenging than usual image classification tasks since ultrasound images are difficult to collect and usually contain lots of noise. This paper proposes a novel image classification framework for small-scaled and noisy ultrasound image datasets. The framework first transforms images into discrete index grids. The index grids use discrete indices encoding the local texture patterns of the images. Then, it will conduct classification based on index grids. The proposed framework can significantly reduce the impact of noise as well as the amount of training data that needed. Comparing with existing models, the proposed framework is a lite model and has better explainability. We evaluated the proposed approach on two public ultrasound image datasets for thyroid nodule classification and breast nodule classification. The experiment results show that the proposed approach achieves the new state-of-the-art. 1
Unique SMYD5 Structure Revealed by AlphaFold Correlates with Its Functional Divergence

SMYD5 belongs to a special class of protein lysine methyltransferases with an MYND (Myeloid-Nervy-DEAF1) domain inserted into a SET (Suppressor of variegation, Enhancer of Zeste, Trithorax) domain. Despite recent advances in its functional characterization, the lack of the crystal structure has hindered our understanding of the structure-and-function relationships of this most unique member of the SMYD protein family. Here, we demonstrate the reliability of using AlphaFold structures for understanding the structure and function of SMYD5 by comparing the AlphaFold structures to the known crystal structures of SMYD proteins, using an inter-residue distance maps-based metric. We found that the AlphaFold confidence scores are inversely associated with the refined B-factors and can serve as a structural indicator of conformational flexibility. We also found that the N-terminal sequence of SMYD5, predicted to be a mitochondrial targeting signal, contains a novel non-classical nuclear localization signal. This sequence is structurally flexible and does not have a well-defined conformation, which might facilitate its recognition for SMYD5’s cytonuclear transport. The structure of SMYD5 is unique in many aspects. The “crab”-like structure with a large negatively charged cleft provides a potential binding site for basic molecules such as protamines. The less positively charged MYND domain is associated with the undetectable DNA-binding ability. The most surprising feature is an incomplete target lysine access channel that lacks the evolutionarily conserved tri-aromatic arrangement, being associated with the low H3/H4 catalytic activity. This study expands our understanding of the SMYD protein family from a classical two-lobed structure to a structure of its own kind, being as a fundamental determinant of its functional divergence.
Learning Lipschitz-Controlled Activation Functions in Neural Networks for Plug-and-Play Image Reconstruction Methods

Ill-posed linear inverse problems are frequently encountered in image reconstruction tasks. Image reconstruction methods that combine the Plug-and-Play (PnP) priors framework with convolutional neural network (CNN) based denoisers have shown impressive performances. However, it is non-trivial to guarantee the convergence of such algorithms, which is necessary for sensitive applications such as medical imaging. It has been shown that PnP algorithms converge when deployed with a certain class of averaged denoising operators. While such averaged operators can be built from 1-Lipschitz CNNs, imposing such a constraint on CNNs usually leads to a severe drop in performance. To mitigate this effect, we propose the use of deep spline neural networks which beneﬁt from learnable piecewise-linear spline activation functions. We introduce “slope normalization” to control the Lipschitz constant of these activation functions. We show that averaged denoising operators built from 1-Lipschitz deep spline networks consistently outperform those built from 1-Lipschitz ReLU networks.
Zero-Sum Stochastic Stackelberg Games

Zero-sum stochastic games have found important applications in a variety of fields, from machine learning to economics. Work on this model has primarily focused on the computation of Nash equilibrium due to its effectiveness in solving adversarial board and video games. Unfortunately, a Nash equilibrium is not guaranteed to exist in zero-sum stochastic games when the payoffs at each state are not convex-concave in the players' actions. A Stackelberg equilibrium, however, is guaranteed to exist. Consequently, in this paper, we study zero-sum stochastic Stackelberg games. Going beyond known existence results for (non-stationary) Stackelberg equilibria, we prove the existence of recursive (i.e., Markov perfect) Stackelberg equilibria (recSE) in these games, provide necessary and sufficient conditions for a policy profile to be a recSE, and show that recSE can be computed in (weakly) polynomial time via value iteration. Finally, we show that zero-sum stochastic Stackelberg games can model the problem of pricing and allocating goods across agents and time. More specifically, we propose a zero-sum stochastic Stackelberg game whose recSE correspond to the recursive competitive equilibria of a large class of stochastic Fisher markets. We close with a series of experiments that showcase how our methodology can be used to solve the consumption-savings problem in stochastic Fisher markets.

Gene flow and genetic divergence among mainland and insular populations across the southwestern range of the Eurasian treecreeper

43 The Eurasian treecreeper ( Certhia familiaris ) comprises two mitochondrial lineages that 44 diverged during the mid-Pleistocene. One paleoendemic lineage has an allopatric range 45 currently restricted to the Island of Corsica and the Caucasus region, whereas the 46 second one has a very large Eurasian range. Here we used microsatellites (N = 6) and 47 mitochondrial DNA (COI) to assess the genetic structure of insular and mainland 48 populations from Corsica, mainland France and Central Italy (N = 258) and the level of 49 mitochondrial and nuclear gene flow among these populations. Concordant with the 50 mtDNA signal, microsatellites results clearly demonstrate that the Corsican population 51 ( C. f. corsa ) is strongly divergent from nearby mainland populations ( C. f. macrodactyla ). 52 Microsatellite data also support significant divergence and low gene flow between the 53 Central Italian and mainland French populations. Our results suggest low nuclear gene 54 flow from the mainland into Corsica and no mitochondrial gene flow. Sporadic gene 55 flow from the nearby mainland may explain the presence of continental nuclear alleles 56 in the genome of 5% of sampled insular birds. Our study confirms the existence of an 57 endemic Corsican treecreeper lineage with important conservation value. Our results 58 also imply that Eurasian treecreepers from Central Italy constitute a distinct 59 management unit. 60 61 62 63
CrowdPickUp: Task Pick-up in the Wild

This thesis investigates the feasibility and performance of different types of crowdsourcing tasks picked-up in the wild i.e., situated, location-based and general through the implementation and evaluation of the CrowdPickUp crowdsourcing platform. We describe in detail the implementation process of CrowdPickUp, which we then used in a study where workers could earn coins on the basis of task completion and use their earned coins to buy different available items of their own choice using CrowdPickUp’ s web shop integrated within our system. During the study, we recorded the average completion time and accuracy of different crowdsourcing tasks. The key findings show that our platform was able to generate high quality contributions in a composite environment. Finally, we conclude the thesis by discussing the importance and usefulness of different crowdsourcing tasks designed for our crowdsourcing system and our possible future work within the area of crowdsourcing task-pickup system.
MPC to optimise performance in power-assisted manipulation of industrial objects

A 1-DOF power-assist robotic system (PARS) is developed using a linear actuator for vertical manipulation of heavy objects in collaboration with its human user. Human's differential perception of inertia and gravity is considered in the manipulation dynamics, and an admittance-type feedback position control scheme is designed to control the motion of the system. A human manipulates a heavy object with the robot in harmonic motion (the object is repeatedly lifted up and lowered down). A common performance index for the human and the robot for the collaborative task is derived in terms of manipulation velocity and precision. An event-triggered model predictive control (MPC) scheme is designed to maintain optimal performance of the robot and the human through maintaining optimum robot velocity and precision at the events when low performance is observed. Results show that the weight-perception-based control helps produce satisfactory collaborative performance, and the MPC is proven effective to maintain optimal performance and improved human–robot interaction. The findings are useful to develop predictive control strategies for human-friendly PARSs for manipulating heavy objects in industries in particular, and for other variable-speed electric drive systems for industrial applications, in general.
Vibration Analysis of a Mechanical System Composed of Two Identical Parts

: - The aim of the paper is to analyze the free vibration of a symmetrical, spatial structure made up of bars, obtained by joining two identical subsystems. It is a real structure, encountered in civil engineering. In the literature, there are papers that have established vibration properties of structures with symmetry. In the paper, we propose to see if these properties apply to a structure made up by two identical, mirror symmetrical substructures and linked by common elements.
Generation and Evaluation of Reference Samples as part of an Evacuated Canister Interlaboratory Study

Generation and Evaluation of Reference Samples as part of an Evacuated Canister Interlaboratory Study Dru Burns Evacuated canisters offer an opportunity to expand on the way volatile organic compounds (VOCs) are measured in indoor air quality investigations, industrial hygiene assessments, and emergency response scenarios. There is a growing need for alternative sampling methods for VOCs as traditional sorbent tube sampling methods may not adequately capture the multitude of chemicals present in mixed exposure environments due to sorbentanalyte specificity. This study is part of a larger work designed to address this need across a suite of 17 VOCs. This study assesses generation and evaluation methods for the production of reference evacuated canister samples as part of an ASTM-style interlaboratory study. The interlaboratory study was designed to assess evacuated canister method performance for the development of a National Institute for Occupational Safety and Health (NIOSH) Manual of Analytical Methods protocol. The reference canister samples were generated in two concentration ranges (part-permillion and part-per-billion) and at three nominal concentration levels within the two ranges. For the PPB range, samples were generated using either a flow-based dilution or combination pressure dilution and canister-to-canister transfer technique. For the PPM range, samples were generated by either the combination pressure dilution and canister-to-canister transfer technique, or a manifold dilution method. The reference canister samples were analyzed via gas chromatography-mass spectrometry (GC-MS). The performance of three preparation methods and three analytical methods were assessed by the NIOSH 95% confidence interval on accuracy criterion. Results indicate that method accuracy is concentration dependent with respect to certain combinations of analytical method, preparation technique, and analyte. Some sample preparation techniques were found to be better for certain groups of compounds and at certain concentration ranges. All 17 VOCs passed the NIOSH accuracy criterion for the PPM range when prepared using the pressure dilution technique and analyzed via a 1 cc loop injection into a GC-MS. For the PPB range of concentration levels, 15 VOCs passed the NIOSH accuracy criterion when prepared by the pressure dilution method and analyzed via a 250 cc, cryogenically concentrated injection into a GC-MS.

Sampling strategies to estimate suspended sediment concentration for turbidimeter calibration

The influx of sediments carried by rivers can be measured continuously using a turbidimeter through the indirect relationship between turbidity and suspended sediment concentration (SSC). However, this process is dependent on obtaining water samples with suspended sediments to calibrate the turbidimeter. Sampling can be carried out through different methods, resulting in errors and uncertainties in estimating the SSC. Four different possibilities for the composition of the calibration curve were tested in order to evaluate the effectiveness of the turbidimeter calibration for different sampling strategies. The study was conducted in 2012 and 2013 in two catchments in southern Brazil that had a strong sediment yield impact. The results indicate that sampling during rainfall events generate a significant and representative SSC for the turbidimeter calibration. The use of an integrating sampler for synthetic samples provides an effective calibration, but overestimates SSC compared to calibration from rainfall event sampling. The samples collected at fixed intervals - weekly and daily - generated an insufficient amount of data and are not representative of real sediment concentrations of the catchments. e concentração de sedimentos em suspensão (CSS). Entretanto, isso é dependente da obtenção de amostras com sedimentos em suspensão para a calibração do turbidímetro, a qual pode ser realizada de diferentes formas, originando erros e incertezas na estimativa da CSS. No intuito de avaliar a eficácia de diferentes estratégias de amostragem para a calibração do turbidímetro foram testadas quatro diferentes possibilidades para a composição da curva de calibração. O trabalho foi realizado em duas bacias hidrográficas no sul do Brasil com forte impacto na produção de sedimentos entre 2012 e 2013. Os resultados indicam que a amostragem durante eventos gera uma quantidade significativa e representativa de valores de CSS para a calibração. O uso do amostrador integrador no tempo para a obtenção de amostras sintéticas permite uma boa estratégia de calibração, mas superestima os valores de CSS em relação à calibração com amostras de eventos. As amostras coletadas em intervalos fixos (semanais e diários) geram uma quantidade insuficiente de dados e não representativos das concentrações de sedimentos que ocorrem nas bacias.

A Governance Approach of Emotion in Family Business: Towards a Multi-level Integrated Framework and Research Agenda

: While emotion in family business is beginning to garner closer attention among researchers, the nexus of emotion management and governance has received little attention to date. In this essay, we reflect on and extend the Special Issue contributions by integrating the emotion management literature with the family business and governance literatures. We suggest a governance approach of emotion through a multilevel integrated framework. We introduce “ emotion governance ” as an overarching set of informal and formal mechanisms that are rooted and developed in the embedded family business contexts. We argue that emotion governance influences the explicit emotion management strategies of family business members at different stages: ex-ante (incentive alignment), during the process (education and support), and ex-post (monitoring). It thereby contributes to ensure their account-abilityinlinewithfamilybusinesscontinuity.Consideringtheheterogeneityoffamily businesses, we capture nuances in our framework across family business archetypes through a series of propositions. We chart an agenda for future research to advance the development of a theory of family business governance inclusive of emotion.
Default, Liquidity and Crises : An Econometric Framework

: In this paper, we present a general discrete-time aﬃne framework aimed at jointly modeling yield curves associated with diﬀerent debtors. The underlying ﬁxed-income securities may diﬀer in terms of credit quality and/or in terms of liquidity. The risk factors follow conditionally Gaussian processes, with drifts and variance-covariance matrices that are subject to regime shifts described by a Markov chain with (historical) non-homogenous transition probabilities. While ﬂexible, the model remains tractable. In particular, bond prices are given by quasi-explicit formulas. Various numerical examples are proposed, including a sector-contagion model and credit-rating modeling.
COnTROVERsIEs In nEuROsuRgERy. CRAnIOphARyngIOmA: FAVORIng pARTIAL ExCIsIOn

Craniopharyngiomas are uncommon tumors and their management remains controversial. Despite gross total resection, recurrences can occur in 15-43% during long-term follow-up of more than 10 years. Furthermore, radical surgery can be associated with complications associated with hypothalamic damage, which can lead to a poor quality-of-life. Limited surgery followed by adjuvant radiotherapy (RT) can provide excellent long-term tumor control with minimum complications and good functional outcome. RT can however, produce insidious onset of hypopituitarism and vasculopathy. Secondary malignancies are a rare complication of RT. Modern radiation techniques and intracystic radiation can reduce these complications. Intracystic radiation is highly effective for cystic craniopharyngiomas. Intracystic bleomycin (ICB) and interferon alpha (IFN) are rarely curative, but can produce long lasting control of tumor cysts and this is very useful in very young children who may not tolerate radical surgery or RT. IFN has fewer toxicity issues compared to ICB.

The DNA content of polyploid cells sometimes decreases during subculturing. The mechanism of DNA reduction is not yet known. Precise measurements of DNA decay and related alterations in polyploid cells will be required to understand the mechanism. Diploid, tetraploid and octaploid Meth-A cells were continuously cultured for 244 d and the cellular DNA content was measured from the DNA histograms. The DNA content decays gradually with day t as expressed by f(t) Ip exp{ G(t)}, where Ip is the initial ploidy, G(t) at/{exp( bt) ct}, and a, b and c are the following parameters: a 0.026, b 0.01 and c 0.0175 (for tetraploid cells) or c 0.01 (for octaploid cells). The DNA content of diploid Meth-A cells was constant within the experimental errors. The DNA loss of polyploid cells was confirmed by a decrease in chromosome number. The cellular morphology changed in diploid and octaploid Meth-A cells, but not in tetraploid cells, suggesting that DNA loss and morphology alteration are independent. The doubling time shortened with culture time in the tetraploid and octaploid cells. The findings suggested that chromosomes are not independent in polyploid cells.
