Pricing and location decisions in multi-objective facility location problem with M/M/m/k queuing systems

ABSTRACT This article presents a new multi-objective model for a facility location problem with congestion and pricing policies. This model considers situations in which immobile service facilities are congested by a stochastic demand following M/M/m/k queues. The presented model belongs to the class of mixed-integer nonlinear programming models and NP-hard problems. To solve such a hard model, a new multi-objective optimization algorithm based on a vibration theory, namely multi-objective vibration damping optimization (MOVDO), is developed. In order to tune the algorithms parameters, the Taguchi approach using a response metric is implemented. The computational results are compared with those of the non-dominated ranking genetic algorithm and non-dominated sorting genetic algorithm. The outputs demonstrate the robustness of the proposed MOVDO in large-sized problems.
Approximate distributions of noise power measurements

The frequency functions of certain spectral estimates are studied analytically and numerically. An approximation is obtained for the case of a Poisson weight function and compared to the true distribution. The eigenvalues of products of Toeplitz matrices play a crucial role in the sampling theory of quadratic forms; an approximation to their distribution is discussed and its accuracy studied numerically. This leads to approximate probability densities which are thought to be valid for moderate or even small sample sizes.
McOmet: Multimodal Fusion Transformer for Physical Audiovisual Commonsense Reasoning

Physical commonsense reasoning is essential for building reliable and interpretable AI systems, which involves a general understanding of the physical properties and affordances of everyday objects, how these objects can be manipulated, and how they interact with others. It is fundamentally a multi-modal task, as physical properties are manifested through multiple modalities, including vision and acoustics. In this work, we present a unified framework, named Multimodal Commonsense Transformer (MCOMET), for physical audiovisual commonsense reasoning. MCOMET has two intriguing properties: i) it fully mines higher-ordered temporal relationships across modalities (e.g., pairs, triplets, and quadruplets); and ii) it restricts the cross-modal flow through the feature collection and propagation mechanism along with tight fusion bottlenecks, forcing the model to attend the most relevant parts in each modality and suppressing the dissemination of noisy information. We evaluate our model on a very recent public benchmark, PACS. Results show that MCOMET significantly outperforms a variety of strong baselines, revealing powerful multi-modal commonsense reasoning capabilities.
Sirt6 Activation Ameliorates Inflammatory Bone Loss in Ligature-Induced Periodontitis in Mice

Periodontitis is an inflammatory disease caused by microorganisms that induce the destruction of periodontal tissue. Inflamed and damaged tissue produces various inflammatory cytokines, which activate osteoclasts and induce alveolar bone loss and, eventually, tooth loss. Sirt6 expression suppresses inflammation and bone resorption; however, its role in periodontitis remains unclear. We hypothesized that Sirt6 has a protective role in periodontitis. To understand the role of Sirt6 in periodontitis, we compared periodontitis with ligature placement around the maxillary left second molar in 8-week-old control (C57BL/6J) male mice to Sirt6-overexpressing Tg (Sirt6Tg) mice, and we observed the resulting phenotypes using micro-CT. MDL801, a Sirt6 activator, was used as a therapy for periodontitis through oral gavage. Pro-inflammatory cytokines and increased osteoclast numbers were observed in alveolar bone tissue under periodontitis surgery. In the same condition, interestingly, protein levels from Sirt6 were the most downregulated among sirtuins in alveolar bone tissue. Based on micro-CT and CEJ-ABC distance, Sirt6Tg was observed to resist bone loss against ligature-induced periodontitis. Furthermore, the number of osteoclasts was significantly reduced in Sirt6Tg-ligated mice compared with control-ligated mice, although systemic inflammatory cytokines did not change. Consistent with this observation, we confirmed that bone loss was significantly reduced when MDL801, a Sirt6 activator, was included in the ligation mouse model. Our findings demonstrate that Sirt6 activation prevents bone loss against ligature-induced periodontitis. Thus, a Sirt6 activator may provide a new therapeutic approach for periodontitis.
Association between High-Sensitivity C-Reactive Protein and Blood Pressure Variability in Subacute Stage of Ischemic Stroke

The determinants of blood pressure variability (BPV) are complex. We aimed to evaluate whether circulating high-sensitivity C-reactive protein (hsCRP) is associated with short-term BPV during the subacute stage of ischemic stroke. In this observational study, a consecutive series of acute ischemic stroke patients who underwent 24 h ambulator blood pressure monitoring (ABPM) during day 4 to 10 after onset were enrolled. Multivariable linear regression models were constructed to assess relationships between hsCRP and BPV. Among a total of 325 patients analyzed, the mean age was 60 years old and 72% were male. The SD, CV, ARV of 24 h SBP and DBP were more likely to be higher in patients with hsCRP ≥ 2 mg/L, and these predispositions remained unchanged in linear regression analyses after adjusting for possible confounding factors, with a dose-response relationship when patients were additionally categorized into quartiles according to hsCRP levels using the lowest quartile as a reference category. In contrast, similar results were observed for the mean of SBP but not the mean of DBP. These results indicate that hsCRP is dose-dependently associated with short-term BPV during the subacute stage of ischemic stroke. These findings suggested that patients with a higher level of hsCRP tended to have larger blood pressure fluctuations.

Nous suggerons quelques directions de recherches destinees a une meilleure comprehension de la translocation en termes de transport membranaire
EVALUATION OF A SLAM-BASED POINT CLOUD FOR DEFLECTION ANALYSIS IN HISTORIC TIMBER FLOORS

Abstract. This paper aims at evaluating the possibility of using wearable mobile mapping solutions as a tool for detecting deflections in timber floors. These construction systems are prone to present this type of damage due to the mechanical properties of the wood (relatively low flexural stiffness and creep behaviour). During this study we have evaluated the chance of introducing an additional stage to the general workflow. This stage is devoted to reduce the noise of the 3D point cloud by using the Statistical Outlier Removal filter in combination with a noise-reduction filter such as the Anisotropic filter, the PointCleannet or the Scored-based denoised networks (Deep Learning methods). According with our results, the use of this strategies improves the quality of the 3D point cloud form a qualitative and quantitative point of view. However, these improvements seem to be not sufficient for using this product as a universal source of information for deflection analysis. In this sense, and according with the sensor and study case exploited, this type of point clouds could be used in floors with 5-8-meter length and a relative deflection of about L/200 or higher.

Energy Shaping of Mechanical Systems via Control Lyapunov Functions with Applications to Bipedal Locomotion

This dissertation presents a method which attempts to improve the stability properties of periodic orbits in hybrid dynamical systems by shaping the energy. By taking advantage of conservation of energy and the existence of invariant level sets of a conserved quantity of energy corresponding to periodic orbits, energy shaping drives a system to a desired level set. This energy shaping method is similar to existing methods but improves upon them by utilizing control Lyapunov functions, allowing for formal results on stability. The main theoretical result, Theorem 1, states that, given an exponentially-stable limit cycle in a hybrid dynamical system, application of the presented energy shaping controller results in a closed-loop system which is exponentially stable. The method can be applied to a wide class of problems including bipedal locomotion; because the optimization problem can be formulated as a quadratic program operating on a convex set, existing methods can be used to rapidly obtain the optimal solution. As illustrated through numerical simulations, this method turns out to be useful in practice, taking an existing behavior which corresponds to a periodic orbit of a hybrid system, such as steady state locomotion, and providing an improvement in convergence properties and robustness with respect to perturbations in initial conditions without destabilizing the behavior. The method is even shown to work on complex multi-domain hybrid systems; an example is provided of bipedal locomotion for a robot with non-trivial foot contact which results in a multi-phase gait.
Analysis and Design of Discrete Ferrite Rings to Improve the Efficiency of Meter-Range Wireless Gap Inductive Power Transfer System

In this article, discrete Ferrite rings (DFRs) applied to cylindrical solenoid coupler (CSC) is proposed. The coupling coefficient between adjacent coils is enhanced and the inductance of the coils is increased by reducing the reluctance in the magnetic circuit. The DFRs-based CSCs magnetic structure is considered to be applied for post insulators. The inductive power transfer (IPT) system based on the abovementioned magnetic structure is used to power the state detection equipment at high potential points. A finite element simulation analysis of the electric field is finished to verify that the addition of DFRs does not affect the insulation properties of the post insulator. The parameters of DFRs are optimized to improve their effect on coupling coefficient and self-inductance based on the finite element method. The multilayer coils and the decoupling series compensation method are analyzed. The circuit model of the three-stage IPT system is built and analyzed. A 1.54 m long-range IPT system prototype is completed to simulate the 110 kV post insulator. A series of experiments are performed to verify the advantages of the proposed DFRs. Efficiency of the meter-range IPT system can reach 75.4%.
Os terrenos tectonoestratigráficos do entorno da parte centro-norte do Cráton do São Francisco

Este trabalho foca a presença de terrenos tectonoestratigráficos proximais situados no entorno da porção centro norte do Cráton de São Francisco. Há casos onde o embasamento de alto grau destes terrenos estarem em visível continuidade física com o embasamento do cráton. Outras vezes estão separados, e em algumas vezes esta passagem/relação não pode ser vista por estar acobertada por sedimentos fanerozoicos. A hipótese de uma “descratonização” em processo foi levantada. Almeida (1981) que então imaginara um cráton maior, no passado geológico (chamou-o de “Cráton Paramirim”, que sofrera processo de descratonização de suas bordas, com o desgaste lateral (tectônico, erosional) e assim com diminuição drástica de suas dimensões originais . A ideia de destruição cratônica (metacratonização) voltou a ser levantada nos últimos anos (Dantas et al. ,2019), com bons argumentos mas não suficientes. Em todos os casos, a deformação brasiliana está presente e dirigida para o interior do cráton, atingindo-o e também as suas coberturas neoproterozoicas. Os terrenos tectonoestratigráficos são considerados como “nativos” ou pertencentes anteriormente ao craton que avizinham, (de acordo com Kearey & al.,2009) Assim sendo a história de uma metacratonização é parcialmente viável, mas precisa ser discutida em termos de forma, causa e tempo. Nem sempre temos processos e dados claros e indiscutíveis. Neste trabalho vamos considerar três áreas do domínio meridional da Província Borborema : a ) Sudeste o Piauí - Noroeste da Bahia- domínios das faixas de dobramento Rio Preto; b) Norte da Bahia até o lineamento Pernambuco- domínios do Sistema de Dobramentos Riacho do Pontal; c) Nordeste-Leste do Craton , do Lineamento Pernambuco até o paralelo de Aracajú, nos domínios do Sistema de Dobramentos Sergipano. Todas esta áreas foram percorridas mais de uma vez pelos autores, oferecendo-lhes temas chamativos para uma discussão. Problemas existem e serão discutidos à luz do nosso conhecimento atual
Muonium donor in rutile TiO 2 and comparison with hydrogen

Muonium is like hydrogen, but with a positively charged muon instead of a proton at the center. Observing muon spin rotation in a single crystal of TiO${}_{2}$, and comparing to existing data for hydrogen, the authors demonstrate that the defect configuration and electronic structure are the same for both. This provides important support for research which uses muons as a substitute for hydrogen in semiconductors.
Improving Posture Accuracy of Non-Holonomic Mobile Robot System with Variable Universe of Discourse

This paper presents a method to decrease imprecision and inaccuracy that have the tendency to influence the posture of non-holonomic mobile by using the adaptive tuning of universe of discourse. As such, the primary objective of the study is to force the posture error of x(t), y(t) and θ(t) towards zero. Hence, for each step of tuning the fuzzy domain, about 20% of imprecision and inaccuracy had been added automatically into the variable universe fuzzy, while the control input was bound via scaling gain. Furthermore, the experimental results showed that the tuning of universe fuzzy parameters could increase the performance of the system from the aspects of response time and error for steady state through better control of inaccuracy. Besides, the domains of universe fuzzy input [-4,4] and output [0,6] exhibited good performance in inching towards zero values as the steady state error was about 1% for x(t) position, 0.02% for y(t) position, and 0.16% for θ(t) orientation, whereas the posture error in the given reference was about 0.0002%.

Axiomatisation of Hybrid Logic

In this report, we study the hybrid logics with nominals and operator @. We recall ten Cate’s method to simulate hybrid logic using modalities, in what he calls nice frames, and we show that the hybrid logic of a class of frames is the modal logic of the class of its corresponding nice frames. Then, we expand this idea by considering the closure of the class of nice frames under disjoint unions, bounded morphic images, ultraroots and generated subframes, and we characterise this new class of frames. Using these notions, we axiomatise the hybrid logic of any elementary class of frames. As last, we study stable logics, which are hybrid logics axiomatised by modal axioms together with hybrid axioms common to any hybrid logic. We show that the hybrid logic of any elementary modally definable class of frames, or of any elementary class of frames closed under disjoint unions, bounded morphic images, ultraroots and generated subframes, are stable.

Modélisation de la réponse Immunitaire T-CD8 : analyse mathématique et modèles multiéchelles

L'infection d'un organisme par un agent pathogene declenche l'activation des lymphocytes T-CD8 et l'initiation de la reponse immunitaire. Il s'ensuit un programme complexe de proliferation et de differenciation des lymphocytes T-CD8, controle par l'evolution de leur contenu moleculaire. Dans ce manuscrit, nous presentons deux modeles mathematiques de la reponse T-CD8. Le premier se presente comme une equation differentielle a impulsions grâce a laquelle nous etudions l'effet du partage inegal des proteines lors des divisions cellulaires sur la regulation de l'heterogeneite moleculaire. Le second est un modele a base d'agents couplant la description d'une population discrete de lymphocytes T-CD8 a celle du contenu moleculaire de ces derniers. Ce modele s'avere capable de reproduire les differentes phases caracteristiques de la reponse T-CD8 aux echelle cellulaire et moleculaire. Ces deux travaux supportent l'hypothese que la dynamique cellulaire observee in vivo est le reflet de l'heterogeneite moleculaire qui structure la population de lymphocytes T-CD8
Role of Glutamate Receptor-related Biomarkers in the Etiopathogenesis of ADHD

Objective Pathways associated with glutamate receptors are known to play a role in the pathophysiology of attention-deficit hyperactivity disorder (ADHD). However, cyclin-dependent kinase 5 (CDK5), microtubule-associated protein-2 (MAP2), guanylate kinase-associated protein (GKAP), and postsynaptic density 95 (PSD95), all of which are biomarkers involved in neurodevelopmental processes closely related to glutamatergic pathways, have not previously been studied in patients with ADHD. The main purpose of this study was to evaluate the plasma levels of CDK5, MAP2, GKAP, and PSD95 in children with ADHD and investigate whether these markers have a role in the etiology of ADHD. Methods Ninety-six children with ADHD between 6 and 15 years of age and 72 healthy controls were included in the study. Five milliliters of blood samples were taken from all participants. The samples were stored at −80°C until analyzed by the enzyme-linked immunosorbent assay method. Results Statistically significantly lower CDK5 levels were observed in children with ADHD than in healthy controls (p = 0.037). The MAP2, GKAP, and PSD95 levels were found to be statistically significantly higher in the ADHD group than in healthy controls (p = 0.012, p = 0.009, and p = 0.024, respectively). According to binary regression analysis, CDK5 and MAP2 levels were found to be predictors of ADHD. Conclusion In conclusion, we found that a close relationship existed between ADHD and glutamatergic pathways, and low levels of CDK5 and high levels of MAP2 and GKAP played a role in the etiopathogenesis of ADHD.

Vibro-acoustic simulation of damped orthotropic plates with the wave based method

The wave based method was developed as an efficient methodology for the steady state simulation of vibroacoustic systems. So far this method could only be used to predict the behaviour of simple panels made out of isotropic materials. With the current rise in importance of lightweight composite panels, there is increasing interest in the efficient simulation of panels with direction dependent properties and more complex damping behaviour. To address this need, in this paper, the application range of the wave-based method is expanded in two directions. In a first step the isotropic material model is extended towards an orthotropic one. Second, a versatile damping model, based on the Augmented Hooke’s Law, is integrated into the methodology. Next, the method is applied to three cases. The first one consists of a rectangular composite panel that is excited by a distributed load. In the second case, a vibro-acoustic model is studied by coupling the panel to an acoustic cavity with a simple geometry. Lastly, a model is made of an existing vibro-acoustic test setup on which the composite panel is mounted. Results are compared to a FEM reference model.
