description: We study the interpretation of Lattice data about the thermodynamics of the deconfinement phase of SU(3) Yang-Mills theory, in terms of gluon quasiparticles propagating in a background of a Polyakov loop. A potential for the Polyakov loop, inspired by the strong coupling expansion of the QCD action, is introduced; the Polyakov loop is coupled to tranverse gluon quasiparticles by means of a gas-like effective potential. This study is useful to identify the effective degrees of freedom propagating in the gluon medium above the critical temperature. A main general finding is that a dominant part of the phase transition dynamics is accounted for by the Polyakov loop dynamics, hence the thermodynamics can be described without the need for diverging or exponentially increasing quasiparticle masses as $T \rightarrow T_c$, at variance respect to standard quasiparticle models.

description: We investigate the magneto-transport characteristics of nanospintronics single-electron devices. The devices consist of single non-magnetic nano-objects (nanometer size nanoparticles of Al or Cu) connected to Co ferromagnetic leads. The comparison with simulations allows us attribute the observed magnetoresistance to either spin accumulation or anisotropic magneto-Coulomb effect (AMC), two effects with very different origins. The fact that the two effects are observed in similar samples demonstrates that a careful analysis of Coulomb blockade and magnetoresistance behaviors is necessary in order to discriminate them in magnetic single-electron devices. As a tool for further studies, we propose a simple way to determine if spin transport or AMC effect dominates from the Coulomb blockade I-V curves of the spintronics device.

description: Ice forces on offshore structures are often the primary design load condition and it is therefore important that they be understood, and can be predicted accurately. During the design of piers of the Confederation Bridge, various design parameters including ice velocity, ice thickness, rubble height, ride up and ridge keel properties were considered in the assessment of ice action. To study the relationship between design models and reality using the full-scale data, various monitoring programs were initiated at the Confederation Bridge. One of the major projects includes continuous measurement of ice forces on piers P31 and P32. During continuous fourteen years of monitoring, a vast volume of data has been generated from instrumentation system at the piers and management of instrument data is one of the prime objectives of this research. The ice load derived from instrument data and event information and failure observations obtained from ice video analysis has enable study of the relationship between loads at adjacent piers, and also the relationship between various ice parameters including: ice thickness, ice velocity, keel depth, interaction height, presence of rubble or ride-up and their effect on ice actions. The study has also allowed comparing and verifying the results with the existing models.

description: Searching for superconducting materials with high transition temperature (TC) is one of the most exciting and challenging fields in physics and materials science. Although superconductivity has been discovered for more than 100 years, the copper oxides are so far the only materials with TC above 77 K, the liquid nitrogen boiling point. Here we report an interface engineering method for dramatically raising the TC of superconducting films. We find that one unit-cell (UC) thick films of FeSe grown on SrTiO3 (STO) substrates by molecular beam epitaxy (MBE) show signatures of superconducting transition above 50 K by transport measurement. A superconducting gap as large as 20 meV of the 1 UC films observed by scanning tunneling microcopy (STM) suggests that the superconductivity could occur above 77 K. The occurrence of superconductivity is further supported by the presence of superconducting vortices under magnetic field. Our work not only demonstrates a powerful way for finding new superconductors and for raising TC, but also provides a well-defined platform for systematic study of the mechanism of unconventional superconductivity by using different superconducting materials and substrates.

description: We consider the free boundary problem for two layers of immiscible, viscous, incompressible fluid in a uniform gravitational field, lying above a general rigid bottom in a three-dimensional horizontally periodic setting. We establish the global well-posedness of the problem both with and without surface tension. We prove that without surface tension the solution decays to the equilibrium state at an almost exponential rate; with surface tension, we show that the solution decays at an exponential rate. Our results include the case in which a heavier fluid lies above a lighter one, provided that the surface tension at the free internal interface is above a critical value, which we identify. This means that sufficiently large surface tension stabilizes the Rayleigh-Taylor instability in the nonlinear setting. As a part of our analysis, we establish elliptic estimates for the two-phase stationary Stokes problem.

Adaptive contextual regularization for energy minimization based image segmentation
Creators: name: Rao, Josna
Publisher: name: University of British Columbia
Year: 2010

description: Image segmentation techniques are predominately based on parameter-laden optimization processes. The segmentation objective function traditionally involves parameters (i.e. weights) that need to be tuned in order to balance the underlying competing cost terms of image data fidelity and contour regularization. Conventionally, the associated parameters are set through tedious trial and error procedures and kept constant over the image. However, spatially varying structural characteristics, such as object curvature, combined with varying noise and imaging artifacts, significantly complicate the selection process of segmentation parameters. This thesis contributes to the field of image segmentation by proposing methods for spatially adapting the balance between regularization and data fidelity in energy minimization frameworks in an autonomous manner. We first proposed a method for determining the globally-optimum spatially adaptive regularization weight based on dynamic programming. We investigated this weight with a basic minimum-path segmentation framework. Our findings indicated that the globally-optimum weight is not necessarily the best weight as perceived by users, and resulted in poorer segmentation accuracy, particularly for high noise images. We then investigated a more intuitive approach that adapts the regularization weight based on the underlying local image characteristics to more properly address noisy and structurally important regions. This method, which we termed contextual (data-driven) weighting, involved the use of a robust structural cue to prevent excessive regularization of trusted (i.e. low noise) high curvature image regions and an edge evidence measure, where both measures are gated by a measure of image quality based on the concept of spectral flatness. We incorporated our proposed regularization weighting into four major segmentation frameworks that range from discrete to continuous methods: a minimum-path approach [9], Graph Cuts [14], Active Contours Without Edges [24], and a contextual Mumford-Shah based approach [38]. Our methods were validated on a variety of natural and medical image databases and compared against the globally-optimum weight approach and to two alternate approaches: the best possible (least-error) spatially-fixed regularization weight, and the most closely related data-driven spatially adaptive regularization method. In addition, we incorporated existing texture-based contextual cues to demonstrate the applicability of the data-driven weights.

description: In our search for new magnetic massive stars we use the strongest indirect indicator of a magnetic field in B stars, which is periodic variability of UV stellar wind lines occurring in a velocity range symmetric around zero. Our aim is to obtain follow-up spectropolarimetry to search for a magnetic field in magnetic candidate stars. We quantify UV wind line variability, and analyse its time behaviour. The B1/B2V star sigma Lup emerged as a new magnetic candidate star. AAT spectropolarimetric measurements with SEMPOL were obtained. The stellar wind line variations of sigma Lup are similar to what is known in magnetic B stars, but no periodicity could be determined. We detected a longitudinal magnetic field with varying strength and amplitude of about 100 G with error bars of typically 20 G, which supports an oblique magnetic-rotator configuration. The equivalent width variations of the UV lines, the magnetic and the optical line variations are consistent with the well-known photometric period of 3.02 days, which we identify with the rotation period of the star. Additional observations with ESPaDOnS at CFHT strongly confirmed this discovery, and allowed to determine a precise magnetic period. Further analysis revealed that $σ$ Lupi is a helium-strong star, with an enhanced nitrogen abundance and an underabundance of carbon, and has a spotted surface. We conclude that sigma Lup is a magnetic oblique rotator, and is a He-strong star. It is the 4th B star for which a magnetic field is discovered from studying only its wind variability. Like in the other magnetic B stars the wind emission originates in the magnetic equator, with maximum emission occurring when a magnetic pole points towards the Earth. The 3.02 d magnetic rotation period is consistent with the photometric period, with maximum light corresponding to maximum magnetic field. A full paper will be submitted to A&A.

description: Patch potentials arising from the polycrystalline structure of material samples may contribute significantly to measured signals in Casimir force experiments. Most of these experiments are performed in the sphere-plane geometry, yet, up to now all analysis of patch effects has been taken into account using the proximity force approximation which, in essence, treats the sphere as a plane. In this paper we present the exact solution for the electrostatic patch interaction energy in the sphere- plane geometry, and derive exact analytical formulas for the electrostatic patch force and minimizing potential. We perform numerical simulations to analyze the distance dependence of the minimizing potential as a function of patch size, and quantify the sphere-plane patch force for a particular patch layout. Once the patch potentials on both surfaces are measured by dedicated experiments our formulas can be used to exactly quantify the sphere-plane patch force in the particular experimental situation.

description: Cosmic string loops lead to nonlinear baryon overdensities at early times, even before the time which in the standard LCDM model corresponds to the time of reionization. These overdense structures lead to signals in 21cm redshift surveys at large redshifts. In this paper, we calculate the amplitude and shape of the string loop-induced 21cm brightness temperature. We find that a string loop leads to a roughly elliptical region in redshift space with extra 21cm emission. The excess brightness temperature for strings with a tension close to the current upper bound can be as high as 1 degree K for string loops generated at early cosmological times (times comparable to the time of equal matter and radiation) and observed at a redshift of z + 1 = 30. The angular extent of these predicted "bright spots" is of the order 0.1 degree for a value of the string tension equal to the current upper bound. These signals should be detectable in upcoming high redshift 21cm surveys.

description: The non-perturbation theory of electronic dynamic conductivity for open two-barrier resonance tunnel structure is established for the first time within the model of rectangular potentials and different effective masses of electrons in the elements of nano-structure and the wave function linear over the intensity of electromagnetic field. It is proven that the results of the theory of dynamic conductivity, developed earlier in weak signal approximation within the perturbation method, qualitatively and quantitatively correlate with the obtained results. The advantage of non-perturbation theory is that it can be extended to the case of electronic currents interacting with strong electromagnetic fields in open multi-shell resonance tunnel nano-structures, as active elements of quantum cascade lasers and detectors.

description: Entsprechend einem von E.D. Gilles und Mitarbeitern am Institut für Systemdynamik und Regelungstechnik der Universität Stuttgart vorgeschlagenen Konzept wird eine reproduzierbare Qualität der Endprodukte in komplexen verfahrenstechnischen Produktionsprozessen mit Hilfe einer Prozeßführung gewährleistet, die in einer hierarchischen Struktur nach zentral vorgegebenen Kriterien durch lokale Feedback-Steuerungen in den Teilprozessen eine Linearisierung des Input-Output-Verhaltens der Teilprozesse erzwingt. Da in der Regel nicht alle Zustandsgrößen einer Messung zugänglich sind, kann diese Strategie nur asymptotisch realisiert werden, und zwar mit Hilfe eines Beobachters, der Schätzungen für die nicht meßbaren Zustandsgrößen berechnet. Neue, von H.W. Knobloch und Mitarbeitern an der Universität Würzburg gewonnene Ergebnisse zur Theorie nichtlinearer Beobachter gestatten nun einerseits größere Freiheiten bei der Konstruktion des Beobachters und bieten andererseits zusätzlich die Möglichkeit, gewisse Klassen von Störtermen in den Prozeßgleichungen zu identifizieren und damit ihrem Einfluß entgegenzuwirken. An Hand eines konkreten Modellproblems aus der chemischen Verfahrenstechnik, einer exothermen Folgereaktion A → B → C in einem kontinuierlich durchflossenen Rührkesselreaktor, werden die verschiedenen Möglichkeiten dieses Zugangs im Detail diskutiert sowie Strategien zur effektiven Konstruktion der nichtlinearen Beobachter vorgeschlagen.

description: A model predicting Canadian immigrant workers’ job satisfaction was investigated to determine potential differences due to demographic variables. There were 96 participants; 66.7% men, and 33.3% women with an average age of 34 years. Participants completed standardized measures of job satisfaction, workplace attitudes, bicultural competence, English acculturation, and social support. ANOVA and t-test analyses revealed that there were no differences in job satisfaction based on gender or age group, but that workers who had been in Canada for less than one year had significantly lower job satisfaction than those who had been in Canada for more than five years. A regression analysis showed that as workers’ perceptions of a more inclusive workplace environment and social support increased, so did their reported level of job satisfaction. Study limitations and implications for immigrant workers, career practitioners, counsellors, employers, and policy-makers, as well as future research directions are discussed.

description: We present phase-resolved spectroscopy of two new short period low accretion rate magnetic binaries, SDSSJ125044.42+154957.3 (Porb = 86 min) and SDSSJ151415.65+074446.5 (Porb = 89 min). Both systems were previously identified as magnetic white dwarfs from the Zeeman splitting of the Balmer absorption lines in their optical spectra. Their spectral energy distributions exhibit a large near-infrared excess, which we interpret as a combination of cyclotron emission and possibly a late type companion star. No absorption features from the companion are seen in our optical spectra. We derive the orbital periods from a narrow, variable H_alpha emission line which we show to originate on the companion star. The high radial velocity amplitude measured in both systems suggests a high orbital inclination, but we find no evidence for eclipses in our data. The two new systems resemble the polar EF Eri in its prolonged low state and also SDSSJ121209.31+013627.7, a known magnetic white dwarf plus possible brown dwarf binary, which was also recovered by our method.

description: Introduction: Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is an autoimmune disorder in which antibodies attack NMDA receptors at central neuronal synapses. Symptoms include a highly characteristic set of neurological symptoms but also prominent psychiatric manifestations. Misdiagnosis is frequent given the overlap of symptoms with psychiatric manifestations. Case Report:  This is a case of a healthy 26 year old man with history of polysubstance abuse whom complained of intermittent dizziness, fatiguability & myalgia. He also experienced elementary in nature auditory hallucinations which were transient and resolve spontaneously. He presented to the Emergency Department weeks later with psychiatric manifestations. CT brain was normal. He was admitted to the psychiatry ward. Throughout his detention he was restrained & isolated due to provocative behaviour. In view of poor response to optimised poly psychotropics MRI brain done showed multiple T2/FLAIR hyperintense foci in both centrum semiovale, right parietal lobe, right frontal lobe & left temporal lobe. He was treated as old infarct secondary to previous illicit drug abuse. Despite being treated with optimal doses and duration of multiple antipsychotics, his psychosis failed to improve. Due to the atypicality of his psychotic episode, he was investigated for anti NMDA receptor encephalitis, which he tested positive for. He was immediately transferred to the medical ward and treated with IVIG. He subsequently showed improvement. However, he was noted to have regressive personality changes. Conclusion: This case underscores the need for increased awareness and high diagnostic suspicion of this rare clinical syndrome when approaching patients with acute onset of atypical psychosis. Prompt diagnosis is critical as early immunotherapy could dramatically affect outcomes.

description: The EPR parameters g factors and the superhyperfine parameters for the tetrahedral [FeX_4]^- clusters in AgX (X=Cl, Br) are theoretically investigated from the perturbation formulas of these parameters for a 3d^5 ion under tetrahedra by considering both the crystal-field and charge transfer contributions. The related model parameters are quantitatively determined from the cluster approach in a uniform way. The g-shift Δg (=g-g_s, where g_s\approx 2.0023 is the spin only value) from the charge transfer contribution is opposite (positive) in sign and much larger in magnitude as compared with that from the crystal-field one. The importance of the charge transfer contribution increases rapidly with increasing the covalency and the spin-orbit coupling coefficient of the ligand and thus exhibits the order of AgCl

The production rate of 6ΛH undergoing this two-body π- decay is determined to be (2.9\pm2.0)\cdot10-6/K-.

description: Introduction: Anti-platelets are commonly used in managing acute coronary syndrome (ACS). Prevalence of dyspepsia among ACS patients receiving anti-platelet therapy was 47.8 % with epigastric pain and heart burn as the most reported symptoms. This study aimed to assess the association of gastric acid suppressor therapy and incidence of dyspepsia among ACS patients receiving anti-platelets in Hospital Melaka. Methodology: A cross-sectional study was conducted from October 2017 to June 2019. A total of 298 medical ward patients receiving anti-platelet therapy for ACS were recruited. Patients were interviewed using Leeds Dyspepsia Questionnaire to determine the presence of dyspepsia. Results: Two-thirds of study population were on aspirin, 5.7% were on clopidogrel and 29.5 % were on dual anti-platelets (aspirin and clopidogrel). Less than 5.0% of patients on long term anti-platelet therapy reported dyspepsia with heartburn (9.1%) and indigestion (6.7%) as the most troublesome symptoms. 57.1 % of these patients who complained of dyspepsia were prescribed with proton pump inhibitor (PPI) and 28.6 % on H2 receptor antagonist (H2RA). 14.3 % of them were not prescribed with gastric acid suppressant. Discussion / Conclusion: This study found that there is significant number of patients taking gastric acid suppressant therapy experiencing dyspepsia (p= 0.004). There was no association between types of anti-platelets and incidence of dyspepsia among ACS patients with or without gastric acid suppressant. Our study shows that gastric acid suppressants are not effective in preventing dyspepsia. This study may serve as a precedent to assist prescriber in prescribing gastric acid suppressant among ACS patients receiving anti-platelet therapy judiciously.

description: Main Belt comets represent a recently discovered class of objects. They are quite intriguing because, while having a Tisserand invariant value higher than 3, are showing cometary activity. We study the activity of the Main Belt comets making the assumption that they are icy-bodies and that the activity has been triggered by an impact. We determine the characteristics of this activity and if the nowadays impact rate in the Main Asteroid Belt is compatible with the hypothesis of an activity triggered by a recent impact. Due to the fact that the Main Belt comets can be considered as a kind of comets, we apply a thermal evolution model developed for icy bodies in order to simulate their activity. We also apply a model to derive the impact rate, with respect to the size of the impactor, in the Main Belt. We demonstrate that a stable activity can result from a recent impact, able to expose ice-rich layers, and that the impact rate in the Main Belt is compatible with this explanation.

description: We present an experimental feasible scheme to synthesize two-mode continuous-variable entangled states of two superconducting resonators that are interconnected by two gap-tunable superconducting qubits. We show that, with each artificial atom suitably driven by a bichromatic microwave field to induce sidebands in the qubit-resonator coupling, the stationary state of the photon fields in the two resonators can be cooled and steered into a two-mode squeezed vacuum state via a dissipative quantum dynamical process, while the superconducting qubits remain in their ground states. In this scheme the qubit decay plays a positive role and can help drive the system to the target state, which thus converts a detrimental source of noise into a resource.

description: Introduction Higher physical activity has been associated with better mental health among children and adolescents. Findings from a series of national surveys showed that physical inactivity and mental health disorders are more prevalent among ethnic minority students than the ethnic majority in Malaysia. This study explores the influence of mental health factors on physical activity among ethnic minority secondary school students in Malaysia. Methodology Data on 8794 secondary school students were extracted from the National Health and Morbidity Survey 2017. The respondents consisted of Chinese (46.7%), Indian (16.3%), Sabahan (20.3%), Sarawakian (10.5%) and other ethnic groups (6.3%). Four mental health components were assessed: distress, anxiety, depression and suicidal ideation. Probit regression analysis was applied to examine the associations between each mental health component with physical activity, stratified by ethnicity. Results Distress was positively associated with physical activity among Indian students, whereas it was negatively related to physical activity among students from other ethnic groups. Being depressed reduced the probability of being physically active among Sabahan students. However, anxiety and suicidal ideation did not have significant influences on physical activity in any of the ethnic minority groups. Conclusions Mental health plays an important role in determining the level of physical activity among ethnic minority students. Ethnic minority students could benefit from targeted intervention measures that take mental health factors into consideration [Disclaimer: Abstract text might vary slightly from what is displayed in the e-poster]

description: We calculate the exact Kohn-Sham potential that describes, within time-dependent density-functional theory, the propagation of an electron quasiparticle wavepacket of non-zero crystal momentum added to a ground-state model semiconductor. The potential is observed to have a highly nonlocal functional dependence on the charge density, in both space and time, giving rise to features entirely lacking in local or adiabatic approximations. The dependence of the non-equilibrium part of the Kohn-Sham electric field on the local current and charge density is identified as a key element of the correct Kohn-Sham functional.

subject: Thin-Ideal Internalization

description: Although a history of research and social action has led to progress in the areas of race and gender bias, weight bias, or the negative attitudes and beliefs towards people with obesity, has been given considerably less focus. Given the increasing rates of obesity and the increase in the intensity and frequency of weight-bias, research is needed to elucidate factors associated with weight bias. This research quantitatively examined the relationship between three social ideologies, thin-ideal internalization, and social comparison processes in relation to weight bias. Participants were 153 adults from the United States recruited through Amazon.com’s Mechanical Turk. The results suggested that, while social ideology remains significantly associated with weight bias, thin-ideal internalization and social comparisons are also significantly associated with both explicit and implicit weight bias. Future research may want to more closely align with body image research, and investigate the utility of body image interventions for weight bias.

description: This paper studies a stochastic particle method for the numerical treatment of Smoluchowski's coagulation equation. Convergence in probability is established for the Monte Carlo estimators, when the number of particles tends to infinity. The deterministic limit is characterized as the solution of a discrete in time version of the Smoluchowski equation. The results are illustrated by numerical examples.
PDDL2.1 - The Art of the Possible? Commentary on Fox and Long
Creators: name: McDermott, D.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: PDDL2.1 was designed to push the envelope of what planning algorithms can do, and it has succeeded. It adds two important features: durative actions,which take time (and may have continuous effects); and objective functions for measuring the quality of plans. The concept of durative actions is flawed; and the treatment of their semantics reveals too strong an attachment to the way many contemporary planners work. Future PDDL innovators should focus on producing a clean semantics for additions to the language, and let planner implementers worry about coupling their algorithms to problems expressed in the latest version of the language.
Harmonic decomposition of three-particle azimuthal correlations at energies available at the BNL Relativistic Heavy Ion Collider

description: © 2018 American Physical Society. We present measurements of three-particle correlations for various harmonics in Au+Au collisions at energies ranging from sNN=7.7 to 200 GeV using the STAR detector. The quantity (cos(mφ1+nφ2-(m+n)φ3)), with φ being the azimuthal angles of the particles is evaluated as a function of sNN, collision centrality, transverse momentum, pT, pseudorapidity difference, Δη, and harmonics (m and n). These data provide detailed information on global event properties such as the three-dimensional structure of the initial overlap region, the expansion dynamics of the matter produced in the collisions, and the transport properties of the medium. A strong dependence on Δη is observed for most harmonic combinations, which is consistent with breaking of longitudinal boost invariance. An interesting energy dependence is observed when one of the harmonics m,n, or m+n is equal to two, for which the correlators are dominated by the two-particle correlations relative to the second-harmonic event plane. These measurements can be used to constrain models of heavy-ion collisions over a wide range of temperature and baryon chemical potential.

description: © 2018. The American Astronomical Society. All rights reserved. We propose and test a method for applying statistical photometric parallax to main-sequence turnoff stars in the Sloan Digital Sky Survey (SDSS). Using simulated data, we show that if our density model is similar to the actual density distribution of our data, we can reliably determine the density model parameters of three major substructures in the Milky Way halo using the computational resources available on MilkyWay@home (a 20-parameter fit). We fit the stellar density in SDSS stripe 19 with a smooth stellar spheroid component and three major streams. One of these streams is consistent with the Sagittarius tidal stream at 21.1 kpc away, one is consistent with the trailing tail of the Sagittarius tidal stream in the north Galactic cap at 48 kpc away, and one is possibly part of the Virgo Overdensity at 6 kpc away. We find the 1σ widths of these three streams to be 1.0 kpc, 17.6 kpc, and 6.1 kpc, respectively. The width of the trailing tail is extremely wide (41 kpc full width at half maximum). This large width could have implications for the shape of the Milky Way dark matter halo. The width of the Virgo Overdensity-like structure is consistent with what we might expect for a "cloudlike" structure; analysis of additional stripes of data are needed to outline the full extent of this structure and confirm its association with the Virgo Overdensity.

description: Introduction Zika disease is an emerging vector-borne disease in many parts of the world. First isolated in Malaysia in 1966, the seroprevalence and risk factors of ZIKV in Malaysia are unknown. Methodology We conducted a population-based serosurvey in three states between April to July 2017. Blood samples were taken from 1,261 respondents in Johor (n=388), Sabah (n=409) and Kedah (n=464) were tested for the presence of antibodies against Zika virus (ZIKV) by anti-ZIKV IgM and IgG ELISA. Seroprevalence of ZIKV was estimated based on seropositivity of either anti-ZIKV IgM or IgG or both. Respondents were interviewed using a structured questionnaire and multiple logistic regression analysis was used to identify risk factors for ZIKV seropositivity.   Results Kedah had the highest ZIKV seroprevalence (33.9%), followed by Sabah (23.6%) and Johor (12.7%). Overall seroprevalence of ZIKV was estimated at 24.1%. Age (higher likelihood of seropositivity among age 18 years and above)and ethnicity (higher among 'Others' ethnic group) were significantly associated with ZIKV seropositivity, whereas self-reported history of dengue fever, wearing long trousers or sleeves and having screened windows at home were associated with less risk of ZIKV seropositivity. Discussion/Conclusions Our findings suggest that ZIKV is endemic and co-circulating with other arboviruses in Malaysia.
