Design of microscale plasmonic devices for temperature change sensing at visible wavelengths

Abstract. Photonic devices used in photonic integrated circuits are very important to understand high performance devices. To increase reliability of these devices, temperature characteristics of these devices need to be investigated. Still, no device that can simply sense temperature change in microscale exists. Hence, we have designed microscale plasmonic devices for temperature change sensing at the wavelength of near 633 nm. The designed device consists of a single- and a multimode plasmonic channel waveguide with two different trench depths. The designed device utilizes multimode interference of channel plasmon polaritons for sensing temperature change. The designed device can be applied in the range of the temperature change that silver coefficient of thermal expansion does not greatly change, such as the temperature from room temperature to ±30°C. The temperature change sensitivity of the designed device has been numerically confirmed by the finite-difference time-domain method. The temperature change sensitivity of the designed device is a little inferior to that of existing temperature sensing devices. However, the designed device can be realized under one hundredth of the size of existing temperature change sensing devices.

Computational micro-flow with spectral element method and high Reynolds number flow with discontinuous Galerkin Finite Element Method

In this dissertation, two numerical methods with high order accuracy, Spectral Element Method (SEM) and Discontinuous Galerkin Finite Element Method (DG-FEM), are chosen to solve problems in Computational Fluid Dynamics (CFD). The merits o f these two methods will be discussed and utilized in different kinds o f CFD problems. The simulations o f the micro-flow systems with complex geometries and physical applications will be presented by SEM. Moreover, the numerical solutions for the Hyperbolic Flow will be obtained by DG-FEM. By solving problems with these two methods, the differences between them will be discussed as well. Compressible Navier-Stokes equations with Electro-osmosis body force and slip boundary conditions are solved to simulate two independent models. The third order Adams-Bashforth method on time splitting, and up to the eighth order SEM on space analysis are utilized in our cases o f the electro-osmosis flow (EOF). To solve the body force caused by EOF, simplification o f the Poisson-Boltzmann is discussed in details. Results show that SEM can clearly simulate the electric double layers in EOF. Compared with the finite element method, which uses h-refmement to increase resolution, SEM has obvious advantages by using hp-refmement. The other case for SEM is the simulations o f drug delivery through the micro needle. The drug flowing inside the needle is treated as a micro-flow system with complex geometry, while the process o f drug fluxing in human skin is developed as in the case o f CFD problem in porous media. Incompressible Navier-Stokes equations and Darcy-Brinkman equations are solved to simulate the drug flowing inside the needle and diffusing in human skin, respectively. Results are compared with COMSOL simulation, experimental data, and numerical solutions from Smoothed Particle Hydrodynamics (SPH). The high order DG-FEM method is chosen to do research on Hyperbolic Flow.

Biological Activities and Ecological Significance of Fire Ant Venom Alkaloids

Venoms produced by arthropods act as chemical weapons to paralyze prey or deter competitors. The utilization of venom is an essential feature in the biology and ecology of venomous arthropods. Solenopsis fire ants (Hymenoptera: Formicidae) are medically important venomous ants. They have acquired different patterns of venom use to maximize their competitive advantages rendered by the venom when facing different challenges. The major components of fire ant venom are piperidine alkaloids, which have strong insecticidal and antibiotic activities. The alkaloids protect fire ants from pathogens over the course of their lives and can be used to defend them from predators and competitors. They are also utilized by some of the fire ants’ natural enemies, such as phorid flies to locate host ants. Collectively, these ants’ diverse alkaloid compositions and functions have ecological significance for their survival, successful invasion, and rapid range expansion. The venom alkaloids with powerful biological activities may have played an important role in shaping the assembly of communities in both native and introduced ranges.

The result of the work, which this thesis represents is the development of new methods for addressing some of the problems within the field. Mainly in robustifying the factorization approach, relaxing the rigidity constrains, and in considering alternative ways of solving the surface estimation problem.
New Ideas for Effective Higgs Measurements

in deutscher Übersetzung Mit einer e ektiven Feldtheorie können die Signaturen neuer Physik im Higgs-Sektor ohne starke eorieannahmen parametrisiert werden. In dieser Arbeit untersuchen wir zwei Aspekte dieses Ansatzes, die für Messungen der Eigenschaen des Higgs-Bosons während Run 2 des LHC relevant sind. Aufgrund der beschränkten Präzision dieser Messungen kann neue Physik im Higgs-Sektor nur dann entdeckt werden, wenn deren typische Energieskala nah am experimentellen Impulsübertrag liegt. Die Näherungen der e ektiveneorie sind daher möglicherweise ungültig. Im ersten Teil dieser Arbeit vergleichen wir die Signaturen mehrerer Modelle von Physik jenseits des Standardmodells mit den entsprechenden Beschreibungen in der e ektiven eorie, untersuchen die Nützlichkeit des e ektiven Modells und zeigen, wie dessen Gültigkeitsbereich vergrößert werden kann. Im zweiten Teil verwenden wirMethoden aus der Informationsgeometrie, umMessungen von Higgs-Eigenschaen zu optimieren. Unser Ansatz basiert auf der Fisher-Information, die die maximale Präzision angibt, mit der Parameter in einem Experiment gemessen werden können. Wir entwickeln Methoden zur Berechnung der Fisher-Information in der Teilchenphysik und wenden sie auf verschiedenen Higgs-Prozesse an. Dabei zeigen wir, wie mit Informationsgeometrie Selektionsschnitte optimiert, die wichtigsten kinematischen Observablen de niert und das Potential vonmodernenmultivariatenMethodenmit dem von Histogramm-basierten Analysen verglichen werden kann.
Experimental Study of a Low-Specific Speed Francis Model Runner during Resonance

An analysis of the pressure in a runner channel of a low-specific speed Francis model runner during resonance is presented, which includes experiments and the development of a pressure model to estimate both the convective and acoustic pressure field from the measurements. The pressure was measured with four pressure sensors mounted in the runner hub along one runner channel. The mechanical excitation of the runner corresponded to the forced excitation from rotor-stator interaction. The rotational speed was used to control the excitation frequency. The measurements found a clear resonance peak in the pressure field excited by the second harmonic of the guide vane passing frequency. From the developed pressure model, the eigenfrequency and damping were estimated. The convective pressure field seems to diminish almost linearly from the inlet to outlet of the runner, while the acoustic pressure field had the highest amplitudes in the middle of the runner channel. At resonance, the acoustic pressure clearly dominated over the convective pressure. As the turbine geometry is available to the public, it provides an opportunity for the researchers to verify their codes at resonance conditions.
Conditional stability in determination of initial data for stochastic parabolic equations

In this paper, we solve two kinds of inverse problems in determination of the initial data for stochastic parabolic equations. One is determination of the initial data by lateral boundary observation on arbitrary portion of the boundary, the second one is determination of the initial data by internal observation in a subregion inside the domain. We obtain conditional stability for the two kinds of inverse problems. To prove the results, we estimate the initial data by a terminal observation near the initial time, then we estimate this terminal observation by lateral boundary observation on arbitrary portion of the boundary or internal observation in a subregion inside the domain. To achieve those goals, we derive several new Carleman estimates for stochastic parabolic equations in this paper.
Elevated transition temperature in Ge doped VO2 thin films

Thermochromic GexV1−xO2+y thin films have been deposited on Si (100) substrates by means of reactive magnetron sputtering. The films were then characterized by Rutherford backscattering spectrometry (RBS), four-point probe electrical resistivity measurements, X-ray diffraction, and atomic force microscopy. From the temperature dependent resistivity measurements, the effect of Ge doping on the semiconductor-to-metal phase transition in vanadium oxide thin films was investigated. The transition temperature was shown to increase significantly upon Ge doping (∼95 °C), while the hysteresis width and resistivity contrast gradually decreased. The precise Ge concentration and the film thickness have been determined by RBS. The crystallinity of phase-pure VO2 monoclinic films was confirmed by XRD. These findings make the use of vanadium dioxide thin films in solar and electronic device applications—where higher critical temperatures than 68 °C of pristine VO2 are needed—a viable and promising solution.
Lévy NMF : un modèle robuste de séparation de sources non-négatives

Dans cet article, nous nous interessons a la separation robuste de sources non-negatives. Nous introduisons les distributions Positives α-stables (PαS), un sous-ensemble de la famille des lois stables, qui modelisent les variables latentes non-negatives. Comme ces distributions sont a queue lourde, elles possedent naturellement une propriete de robustesse aux valeurs aberrantes. En etudiant plus particulierement la loi de Levy, la seule loi PαS dont la densite s’exprime sous forme analytique simple, nous mettons au point un modele de melange dans lequel nous structurons par un modele de factorisations en matrices non-negatives (NMF) les parametres de dispersion des variables de Levy. Ce modele, appele Levy NMF, est estime au sens du maximum de vraisemblance. Nous obtenons egalement un estimateur des sources qui generalise le filtrage de Wiener aux distributions PαS. Des experiences conduites sur des spectrogrammes musicaux et des spectres de fluorescence demontrent le potentiel de ce modele pour decomposer des donnees non-negatives.
Efficacy and safety of SOXIRI versus mFOLFIRINOX in advanced pancreatic cancer

Background: Modified fluorouracil/leucovorin/irinotecan/oxaliplatin (FOLFIRINOX) regimen (mFOLFIRINOX), comprised of fluorouracil, leucovorin, irinotecan and oxaliplatin, is the first-line standard chemotherapy in patients with advanced pancreatic cancer. The S-1/oxaliplatin/irinotecan (SOXIRI) regimen has also been studied recently under similar conditions. This study compared its efficacy and safety. Methods: All cases of locally advanced or metastatic pancreatic cancer treated with the SOXIRI or mFOLFIRINOX regimen in Sun Yat-sen University Cancer Centre from July 2012 to June 2021 were reviewed retrospectively. The data of patients who satisfied the inclusion criteria were compared between two cohorts, including overall survival (OS), progression-free survival (PFS), objective response rate, disease control rate and safety. Results: A total of 198 patients were enrolled in the study, including 102 patients treated with SOXIRI and 96 patients treated with mFOLFIRINOX. There was no significant difference in OS [12.1 months versus 11.2 months, hazard ratio (HR) = 1.04, p = 0.81] or PFS (6.5 months versus 6.8 months, HR = 0.99, p = 0.96) between patients treated with SOXIRI and mFOLFIRINOX. In the subgroup analysis, patients with slightly elevated baseline total bilirubin (TBIL) or underweight patients before chemotherapy were more likely to have a longer OS or PFS from SOXIRI than from mFOLFIRINOX. In addition, the carbohydrate antigen (CA)19-9 decline was a good predictor for the efficacy and prognosis of both chemotherapy regimens. All grade adverse events were parallel in all kinds of toxicities except that anaemia was more common in the SOXIRI group than in the mFOLFIRINOX group (41.4% versus 24%, p = 0.03). The occurrence of any grade 3 to 4 toxicity was similar in the two groups. Conclusions: For locally advanced or metastatic pancreatic cancer patients, the SOXIRI regimen had similar efficacy and controllable safety compared with the mFOLFIRINOX regimen.

Keywords: foreign debt, impact, debt to serve ratio, public saving, Indonesian economy
Data-Adaptive Causal Effects and Superefficiency

Abstract Recent approaches in causal inference have proposed estimating average causal effects that are local to some subpopulation, often for reasons of efficiency. These inferential targets are sometimes data-adaptive, in that they are dependent on the empirical distribution of the data. In this short note, we show that if researchers are willing to adapt the inferential target on the basis of efficiency, then extraordinary gains in precision can potentially be obtained. Specifically, when causal effects are heterogeneous, any asymptotically normal and root-n$n$ consistent estimator of the population average causal effect is superefficient for a data-adaptive local average causal effect.
Locally small Riemann sum property of a vector valued function in locally compact metric space

In this paper, we defined a locally small Riemann sum (LSRS) property relative to volume function θ of vector-valued function on a cell E in a nondiscrete locally compact metric space X. By the definition, if a function f has LSRS property relative to θ on cell E is denoted by f ∈ LSRS(E, θ), then it can be proved that: (i) if f, g ∈ LSRS(E, θ), then f + g ∈ LSRS(E, θ) and αf ∈ LSRS(E, θ) for any real number α ; (ii) if f ∈ LSRS(E, θ) , then f is bounded on E ; (iii) if f ∈ LSRS(E, θ), then f is Henstock integrable relative to θ on E; (iv) if (Y, ‖. ‖) is a complete normed space and f: E → Y is Henstock integrable relative to θ, then f ∈ LSRS(E, θ).
Chromobacterium Violaceum: A Model for Evaluating the Anti-Quorum Sensing Activities of Plant Substances

In the new antibiotic era, the exponential increase in multiresistant bacterial strains has become the main global health problem. Many researchers have focused their efforts on exploring novel or combined strategies for combating bacterial resistance. Good knowledge of the molecular mechanisms of resistance and bacterial virulence factors as key targets provides us with a good basis for resolving the problem. One particularly attractive and promising strategy is to attack the main regulatory “network” of bacterial virulence determinants known as quorum sensing (QS). The inhibition of QS signals will be a novel means of screening more effective quorum-sensing inhibitors (QSIs) and will play a key role in the use of next-generation antimicrobials in the battle against resistance. This motivated the present review to provide a comprehensive clarification of the regulatory mechanisms of quorum-sensing signaling pathways in Chromobacterium violaceum and the discovery of potential plant quorum-sensing inhibitors.
Characterizing the Strategic Impact of Misspecified Beliefs

Previous research has established that the predictions of game theory are quite sensitive to the assumptions made about the players’ beliefs. We evaluate the severity of this robustness problem by characterizing conditions on the primitives of the model—the players’ beliefs and higher-order beliefs about the payoff-relevant parameters—for the behaviour of a given Harsanyi type to be approximated by the behaviour of (a sequence of) perturbed types. This amounts to providing belief-based characterizations of the strategic topologies of Dekel et al. (2006). We apply our characterizations to a variety of questions concerning robustness to perturbations of higher-order beliefs, including genericity of types that are consistent with a common prior, and we investigate the connections between our notions of robustness and the notion of common $p$-belief of Monderer and Samet (1989).
Exosome-mediated long noncoding RNA (lncRNA) PART1 suppresses malignant progression of oral squamous cell carcinoma via miR-17-5p/SOCS6 axis

Background/aim Exosomes derived from oral squamous cell carcinoma (OSCC) could modulate OSCC development. This study aimed to explore effects of exosome-mediated lncRNA PART1 on OSCC cells. Materials and methods This study was performed in Tianjin Medical University Cancer Institute from February 2021 to March 2022. Bioinformatic analysis was performed on the public database GEPIA (http://gepia.cancer-pku.cn/). Exosomes isolated from cell lines squamous cell carcinoma 9 (SCC9) and Centre Antoine Lacassagne-27 (CAL27) were identified by transmission electron microscope and western blot. Exosome-mediated lncRNA PART1, microRNA-17-5p(miR-17-5p) and suppressor of cytokine signaling 6(SOCS6) RNA expressions were assessed by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Cell counting kit-8(CCK-8), caspase-3 activity, and flow cytometry were applied to evaluate OSCC cell viabilities and apoptosis. Meanwhile, OSCC cell migratory ability and invasiveness were evaluated using transwell assay. Bindings between miR-17-5p and lncRNA PART1 or SOCS6 were validated using the luciferase reporter test. Western blot was used for detecting the protein levels of SOCS6, phosphorylated signal transducer and activator of transcription 3 (STAT3) and STAT3. Results According to GEPIA, lncRNA PART1 was downregulated in OSCC tissue samples and cells, and it had a positive correlation with the good prognosis of Head and neck squamous cell cancer (HNSCC) patients. After the exosomes from OSCC cells were isolated and verified, PART1 was then confirmed to be secreted by exosomes. Further, overexpression of exosome-mediated lncRNA PART1 inhibited OSCC cell viabilities, migration, and invasiveness but facilitated OSCC cell apoptosis. PART1 upregulated SOCS6 through sponging miR-17-5p. Moreover, exosome-mediated lncRNA PART1 suppressed the phosphorylation of STAT3. Conclusion Exosome-mediated lncRNA PART1 could mediate the OSCC progression via miR-17-5p/SOCS6 axis in vitro, suggesting that lncRNA PART1 might be a target for treating OSCC.
Lowest Order Mass of KK Graviton Revisited and How It May Affect the Blue Spectrum for Gravitons

The lowest order mass for a KK graviton, as a non-zero product of two branes interacting via a situation similar to Steinhardt’s ekpyrotic universe is obtained, as to an alternative to the present dogma specifying that gravitons must be massless. The relative positions as to the branes give a dynamical picture as to how lowest order KK gravitons could be affected by contraction and then subsequent expansion. Initially we have bulk gravitons as a vacuum state. The massless condition is just one solution to a Stern Liuouville operator equation we discuss, which with a non-zero lowest order mass for a KK graviton permits modeling of gravitons via a dynamical Casmir effect which we generalize using Ruser and Duerrer’s 2007 work. In particular the blue spectrum for (massless gravitons), is revisited, with consequences for observational astrophysics.
