Structure-preserving model order reduction for K-power bilinear systems via Laguerre functions

ABSTRACT This paper presents a series of structure-preserving model order reduction algorithms for K-power bilinear systems via Laguerre functions. The method first aims to rewritten the K-power bilinear system as a general bilinear system and calculate the approximate low-rank factors of the cross Gramian of the bilinear system by combining the idea of Laguerre functions expansion of the matrix exponential function. After that, the approximate balanced system of the K-power bilinear system is constructed by the corresponding projection transformation of each subsystem. In order to achieve the purpose of model order reduction, the states with smaller singular values are then truncated, so as to further obtain the reduced order model. For this approach, there is a disadvantage that unstable systems may be generated although the original one is stable. To alleviate the inadequacies of this approach, we have improved the model reduction procedure, which is based upon the dominant subspace projection method. In addition, we also carried out a correlation analysis on the stability of improved algorithms. Finally, numerical experiments are employed to substantiate the effectiveness of the presented algorithms.

A Case Study of a Chaco Low-Level Jet Event

This paper concentrates on the analysis of the life cycle of the low-level jet (LLJ) during a summer Chaco jet event. This is accomplished through the use of the Eta/Centro de Previsao del Tempo e Estudos Climaticos (CPTEC) regional model, in order to obtain high temporal and spatial detail of the main processes taking place. Both the low-level circulation and the geopotential height evolution at different latitudes are analyzed to provide a more detailed description of the effects of topography and differential warming on the evolution of this current. This study shows that the life cycle of the particular event analyzed is not the same at the different latitudes swept by this well-organized northerly current, expanding from 158 to 328S during two consecutive days. A common feature to all the examined latitudes is the presence of a diurnal cycle linked to local effects, which is more evident during the first day and a half of the simulation. This cycle was identified not only by a nocturnal maximum of the wind, but also by the oscillations of the geostrophic wind close to the surface in response to differential warming over sloping terrain. However, during the second day, the diurnal oscillation is superseded by synoptic-scale forcing. The meridional growth of this northerly current reacts basically to a deepening of the northwestern Argentinean low, consequently becoming a geostrophic response to a synoptic perturbance. How- ever, during the final stages of this event, a northerly wind area located over the southern tip of the current, which notably increases the northerlies' penetration toward higher latitudes, develops. This last extension is mainly due to a component of ageostrophic origin. Evidence is provided in support of the hypothesis that this secondary development is a feedback between the LLJ and the precipitation at the exit region.
A powerful local shear instability in weakly magnetized disks. III - Long-term evolution in a shearing sheet. IV - Nonaxisymmetric perturbations

The nonlinear evolution of the recently identified accretion disk magnetic shear instability is investigated through a series of numerical simulations. Finite-difference computations of the equations of compressible MHD are carried out on an axisymmetric shearing sheet system with periodic boundary conditions designed to approximate a local region within an accretion disk. Initial field configurations that include some net vertical component evolve into a nonlinear, exponentially growing solution with large poloidal velocities and magnetic fields with energies comparable to the thermal energy density. The stability of a purely azimuthal field configuration is examined, and it is found that nonaxisymmetric instability is present, but with a growth time measured in tens of orbital periods. In general, the most rapid growth occurs for very small radial and azimuthal wavenumbers, leading to coherent magnetic field structure in planes parallel to the disk. It is suggested that this instability is a key ingredient for the generation of magnetic fields in disks.
PRE-PROCESSING OF GALAXIES IN THE FILAMENTS AROUND THE VIRGO CLUSTER

Galaxies can be \pre-processed" in the low-density outskirts by ambient medium in the laments or tidal interactions with other galaxies while falling into the cluster. In order to probe how early on and by which mechanisms galaxies can be aected before they enter high-density cluster environments, we are carrying out an atomic hydrogen (Hi) imaging study of a sample of galaxies selected from three lamentary structures around the Virgo cluster. Our sample consists of 14 late-type galaxies, which are potentially interacting with their surroundings. The Hi observations have been done using the Westerbork Synthesis Radio Telescope, the Giant Metrewave Radio Telescope, and the Jansky Very Large Array with column density sensitivity of 3-5 10 19 cm 2 in 3 per channel, which is low enough to detect faint Hi features in the outer disks of galaxies. In this work, we present the Hi data of two galaxies that were observed with GMRT. We examine the Hi morphology and kinematics to nd the evidence for gas-gas and/or tidal interactions, and discuss which mechanism(s) could be responsible for pre-processing in these cases.
How the Presence of a Doctor Known to Patients Impacts a Web-Based Intervention to Promote Physical Activity and Healthy Eating Behaviour in Individuals with an Overweight/Obesity–Hypertension Phenotype: A Randomised Clinical Trial

(1) Background: The ‘Living Better’ web-based programme has shown short- and long-term benefits for body composition and psychological variables in obese patients with hypertension by promoting a healthier lifestyle. To further explore the potential of this programme, in this work we aimed to explore the possible effect of the patient’s ‘own doctor’ appearing in the video content of the Living Better intervention. (2) Methods: A total of 132 patients were randomly assigned either to the experimental (EG, n = 70) or control (CG, n = 62) group (with a doctor the patient knew as ‘their own’ or an ‘unknown doctor’, respectively). The body mass index (BMI), motivation towards physical activity (PA), PA levels, motivation to change one’s eating habits, adherence to the Mediterranean diet, and eating behaviour were all assessed and compared at baseline and post-intervention (12 weeks). (3) Results: The results of this study confirmed the positive effects of the Living Better programme on BMI and external eating style, with significant improvements in these variables in both groups. In addition, in the EG there was higher intrinsic motivation to change eating behaviour (mean difference of 0.9, 95% CI [0.1, 1.6], p = 0.032) and lower amotivation (mean difference of −0.6, 95% CI [−1.2, −0.1], p = 0.027) compared to the CG. (4) Conclusions: This study suggests that the presence of the patients’ own doctor in the audiovisual content of the Living Better intervention did not have significant additional benefits in terms of BMI or external eating style. However, their presence did improve intrinsic motivation and amotivation related to eating habits.
On extremizers for certain inequalities of the k-plane transform and related topics

Author(s): Flock, Taryn Cristina | Advisor(s): Christ, Michael | Abstract: This dissertation is concerned with determining optimal constants and extremizers, functions which achieve them, for certain inequalities arising in harmonic analysis. The main inequality considered is the $L^p$-$L^q$ inequality for the $k$-plane transform. It was shown in cite{C84} that the $k$-plane transform is a bounded operator from $L^p$ of Euclidean space to $L^q$ of the Grassmann manifold of all affine $k$-planes in $R^d$ for certain exponents depending on $k$ and $d$. Specifically, for $1leq qleq d+1$ and $p=frac{dq}{n-d+dq}$ there exists a finite positive constant $A_0g0$ such that[ |T f|_{L^q(M)} leq A_0 |f|_{L^{p}(R^d)}. ] Extremizers of the inequality have previously been shown to exist when $q=2$ by Baernstein and Loss cite{BL97}, when $k=2$ and $q$ is an integer, also in cite{BL97}, when $k=d-1$ and $q=d+1$ by Christ cite{C11}, and when $q=d+1$ for general $k$ by Drouot cite{D11}. In each of these cases, $f_0(x)= (1=|x|^2)^{frac{-(d-k)}{2(p-1)}}$ is an extremizer. When $q=2$ cite{BL97} or $k=n-1$ and $q=d+1$ cite{C11} this extremizer has been shown to be unique up to composition with certain explicit symmetries of the inequality. Chapter ref{chap:exist} contains two proofs that when $q$ is an integer, there exist extremizers, functions which achieve equality in the inequality with the sharp constant. Chapter ref{chap:unique} extends Christ's uniqueness result for the endpoint case from $k=n-1$ to general $k$. In particular, we show that for $q=d+1$ for $kin[1,d-1]$, the extremizing function is unique up to composition with affine maps. This is achieved by modifying the methods of cite{C11} to apply to functions which are only assumed to be measurable $L^p$ functions (rather than smooth $L^p$ functions). Chapter ref{chap:smooth} shows that when $q$ and $frac{1}{p-1}$ are both integers, all extremizers are infinitely differentiable. This involves a family of weighted inequalities for the $k$-plane transform and the analysis of a nonlinear Euler-Lagrange equation. Chapter ref{chap:IBL}, considers the related question of extremizing $n$-tuples of characteristic functions for certain multilinear inequalities of Hardy-Riesz-Brascamp-Lieb-Luttinger-Rogers type. Extremizing $n$-tuples are characterized in a special case. This chapter is joint work with Christ.
Modification of Poly(vinyl chloride) with Bio-Based Cassia Oil to Improve Thermo-Mechanical and Antimicrobial Properties

The purpose of this study was to modify plasticised PVC to obtain a material with antimicrobial properties and selected mechanical properties. Natural cassia oil (CO) was used to modify plasticised PVC materials. The modified material was produced by extrusion. The introduced modifier had a maximum concentration of 20 phr. Rheological and mechanical properties were evaluated, and the glass transition temperature was determined. The antioxidant and antimicrobial activity of the agar diffusion method was investigated by analysing the growth inhibition zones against Enterococcus faecalis and Listeria monocytogenes. A favourable effect of the cassia oil content on the increase in antioxidant activity of the developed polymeric materials was found with an increase in the modifier content and the duration of action (30 days). The largest growth restriction zones were observed for L. monocytogenes, i.e., they showed the highest sensitivity to the modified material. The simultaneous decrease in modulus of elasticity, increase in elongation at break, and decrease in Tg indicate that the modifier has a plasticising effect on PVC. The developed material may find application as an active and/or functional material, especially as an emitter of antimicrobial agents, in the packaging used to store minimally processed food.
Minimum time state feedback control with constrained inputs and states

A state feedback control law that brings the system from a known initial state towards zero in minimum time is proposed. The control law is applicable to linear state space systems with constraints on both the control signals and the states. The type of constraints include bounds on both the input signals and the states, and their derivatives. The proposed method can produce an almost perfect minimum-time control law by feeding back the state vector through precalculated gains. The method contains two design parameters. Depending on the required performance, these two parameters can be tuned in order to trade off computational complexity with time-optimality. Numerical simulations that support the ideas are also given.
Posets,Inclusion Degree Theory and FCA

Formal Concept Analysis (FCA) is an order-theoretic method for the mathematical analysis of scientific data, pioneered by R.Wille in mid 80′s. Over the past twenty years, FCA has been widely studied and become a powerful tool for machine learning, software engineering and information retrieval. In addition to being a technique for classifying and defining concepts from data, FCA may be exploited to discover implications among the objects and the attributes. On the other hand, inclusion degree theory proposed by Prof. Zhang W.X. is a measure theory for order theory. In fact the synthesis between FCA and inclusion degree theory will be greatly advantageous to the further development of such domains as intelligent control, pattern recognition, knowledge processing etc. This paper serves to introduce partially ordered set (poset) and inclusion degree theory to FCA. For this, the authors establish three posets, namely, G poset, M poset as well as GM poset and based on the three posets, they define three inclusion degrees on them. Then they show the relationship between the posets and concept lattice, and prove that the basic concepts such as intents, extents and implications can be reconstructed either by the partial orders or by the inclusion degrees of the posets. These results will be very helpful for people to understand the essence of concepts and the structure of concept lattice in FCA, and can be regarded as the main foundation of quantitative measures which are defined for FCA.
Ultrahigh strain and piezoelectric behavior in relaxor based ferroelectric single crystals

The piezoelectric properties of relaxor based ferroelectric single crystals, such as Pb(Zn1/3Nb2/3)O3–PbTiO3 and Pb(Mg1/3Nb2/3)O3–PbTiO3 were investigated for electromechanical actuators. In contrast to polycrystalline materials such as Pb(Zr,Ti)O3, morphotropic phase boundary compositions were not essential for high piezoelectric strain. Piezoelectric coefficients (d33’s)>2500 pC/N and subsequent strain levels up to >0.6% with minimal hysteresis were observed. Crystallographically, high strains are achieved for 〈001〉 oriented rhombohedral crystals, although 〈111〉 is the polar direction. Ultrahigh strain levels up to 1.7%, an order of magnitude larger than those available from conventional piezoelectric and electrostrictive ceramics, could be achieved being related to an E-field induced phase transformation. High electromechanical coupling (k33)>90% and low dielectric loss <1%, along with large strain make these crystals promising candidates for high performance solid state actuators.

A unified treatment of some theorems on positive matrices

Various theorems on positive matrices are shown to be corollaries of one general theorem, the proof of which bears on Legendre functions, as used in Rockafellar's Convex analysis. 1. Introduction: The main theorem. Let X be a finite set, ((? (x))xeX strictly positive numbers, and H a fixed linear subspace of Rx. We shall prove the following : Theorem 1. There exists a unique {nonlinear) map from Rx to H, denoted ft—>hf, such that 2 texp/(x) - exp hf(x))g(x)/? (x) = 0 xeX for all g in H. 2. A first application: Matrices with prescribed marginals. Given an «-sequence /• = (ri)"=1 and an /w-sequence s=(sj),J! =1 of nonnegative numbers such that 22-i ^i=Yj=\ •*/> denote by <J? (r, s) the set of (n, m) matrices (aiS) with a^O such that ri=^JL1aij and Sj—^X-iO^ for all 1 = 1,2, •••,« and j=l,2, • • • , m. Also, let E={1,2, • ■ ■ ,n} and F={1, 2, ■ • •, m}. We define the linear map c from RE®RF to RExF by:
Particle Motions in a Viscous Fluid

The motion of small particles, drops, and bubbles in a viscous fluid at low Reynolds number is one of the oldest classes of problems in theoretical fluid mechanics, dating at least to Stokes’s (1851) analysis of the translation of a rigid sphere through an unbounded quiescent fluid at zero Reynolds number.
Effect of in-hospital evolocumab therapy on lipoprotein(a) in patients with acute myocardial infarction: a retrospective cohort study and a propensity score matching analysis

Background and purpose: Elevated lipoprotein(a) is associated with an increased risk of atherosclerotic cardiovascular disease. Evolocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, has been shown to reduce lipoprotein(a). However, the effect of evolocumab on lipoprotein(a) in patients with acute myocardial infarction (AMI) is poorly studied. This study aims to investigate the change in lipoprotein(a) under evolocumab therapy in patients with AMI. Methods: This retrospective cohort analysis included a total of 467 AMI patients with LDL-C level >2.6 mmol/L upon admission, among whom 132 received in-hospital evolocumab (140 mg every 2 weeks) plus statin (20 mg atorvastatin or 10 mg rosuvastatin per day) and the remaining 335 received statin only. Lipid profiles at 1-month follow-up were compared between the two groups. A propensity score matching analysis was also conducted based on age, sex, and baseline lipoprotein(a) at a 1:1 ratio using a 0.02 caliper. Results: At the 1-month follow-up, the lipoprotein(a) level decreased from 27.0 (17.5, 50.6) mg/dL to 20.9 (9.4, 52.5) mg/dL in evolocumab plus statin group, but increased from 24.5 (13.2, 41.1) mg/dL to 27.9 (14.8, 58.6) mg/dL in statin only group. The propensity score matching analysis included 262 patients (131 in each group). In subgroup analysis of the propensity score matching cohort stratified by the baseline lipoprotein(a) at cutoff values of 20 and 50 mg/dL, the absolute change in lipoprotein(a) was −4.9 (−8.5, −1.3), −5.0 (−13.9, 1.9), −0.2 (−9.9, 16.9) mg/dL in three subgroups in evolocumab plus statin group, and 0.9 (−1.7, 5.5), 10.7 (4.6, 21.9), 12.2 (2.9, 35.6) mg/dL in three subgroups in statin only group. In comparison to statin only group, evolocumab plus statin group had lower lipoprotein(a) level at 1 month in all subgroups (P < 0.05). Conclusions: In-hospital initiation of evolocumab on a background statin therapy reduced lipoprotein(a) level at 1-month follow-up in patients with AMI. Evolocumab plus statin therapy inhibited the increase in lipoprotein(a) in statin only therapy, regardless of the baseline lipoprotein(a) level.
