description: Ion selectivity (Si) is an important parameter for designing ion-exchange membrane-based process and can possibly be estimated from diffusion properties. Here, we have explored this by comparing diffusion properties (responsible for Si) of multiple cations in heterogeneous Ralex membranes and homogenous Nafion membrane. Analysis also involves a direct comparison between commonly used electrochemical impedance spectroscopy (EIS) and extremely sensitive radiotracer-based method. Ion valence dominantly dictates conductivity in Ralex, unlike Nafion, where both ion hydration and ion valence play equally vital roles. Hence, mutual trend between conductivities/diffusion coefficients (so Si) in Ralex is noticeably different than that in Nafion. Polymer volume fraction analysis shows that electrostatic interaction potential of Ba2+/Eu3+ in Ralex was as high as (~40 mV) that of a significantly restricted diffusion in Nafion. The Si, calculated from EIS-based diffusion parameters, are notably lower than those determined from radiotracer diffusion (Sirad) and actual ion permeation experiments (Sipermeation). The Sirad are always the ones closest to Sipermeation. However, depending upon membrane heterogeneity and ion valence, Sirad may be lower/higher than Sipermeation, and it is difficult to accurately predict actual experimental Si directly from conductivity/diffusion coefficients. Analytical method of diffusion parameters measurement is a key factor too.
title: Novel photonic integrated circuits devices based on AlGaInAs/InP
Creators: name: Sun, Xiao

description: AlGaInAs/InP material system's unique properties, such as a larger conduction band discontinuity (ΔEc = 0.72ΔEg) and a smaller valance band discontinuity have made it an attractive choice for photonic integrated circuits (PIC) devices. In this thesis, several novel PIC devices have been designed, fabricated, and characterized based on conventional 1550 nm AlGaInAs/InP multiple quantum well (MQW) laser diode (LD) epilayer structure.
The first device is the polarization mode converter (PMC), which is monolithically integrated with a sidewall grating (SWG) distributed feedback Bragg (DFB) laser. The study highlights two kinds of PMC with different waveguide structures: the half-ridge waveguide and the stepped-height ridge waveguide. Based on the simulation results, it was observed that the half-ridge waveguide achieved a polarization conversion efficiency (PCE) of approximately 90% with a half-beat length of 1200 μm. In contrast, the stepped-height ridge waveguide demonstrated a significantly superior PCE of 97.3 % with a half-beat length of 490 μm. Subsequently, the stepped-height ridge waveguide PMCs integrated with the SWG DFB laser were fabricated utilizing E-beam lithography and inductively coupled plasma (ICP) etching techniques. The achieved results indicated a PCE of 98.4% over a broad range of DFB injection currents at 1555 nm wavelength and a PCE > 90% over the wavelength range of 1543 to 1568 nm. The second device is the PMC integrated with SWG DFB laser and differential phase shifter (DPS)(100-µm-long) to achieve active polarization control, and a nearly 60° rotation of the Stokes vector on the Poincaré sphere was obtained with a range of DPS bias voltage from 0 V to –3.0 V, which exhibited excellent agreement with the simulation result. 360° rotation of the Stokes vector on the Poincaré sphere is expected by using a 900- µm-long quantum well intermixed (100 nm blueshift) DPS.
The third device presented is the eight-channel electroabsorption modulated lasers (EMLs) array based on sidewall four phase-shifted sampled Bragg gratings(4PS-SBG), a C-band eight-channel EML array is presented, with a channel spacing of 0.8 nm. The use of 4PS-SBG sidewall DFB lasers can preserve high coupling coefficients (0.9 times of continuous uniform gratings) and maintain precise channel spacing control, significantly simplifying the EML device fabrication process, requiring only one metalorganic vapor-phase epitaxy (MOVPE) step and one III-V material etch. The DFB lasers exhibit side mode suppression ratios (SMSRs) greater than 42 dB, while the integrated EAM achieves a 20 dB extinction ratio (ER), and the 3-dB modulation bandwidth is more than 20 GHz.
By the way, I have designed, optimized, and fabricated two innovative InP-based devices: the 1D and 2D topological photonic crystal lasers. However, further optimization of the fabrication processes is required to ensure the functionality of these two devices.

description: The vast majority of resonant systems show a red-shift for the resonance frequency when a perturbation, e.g. losses, are introduced to the system. In contrast, here we report for the first time the experimental demonstration of both red- and anomalous blue-shifting of whispering-gallery modes (WGMs) using dielectric and metallic substrates. The maximum blue-shift is more than three times as large as the expected red-shift, proving that the anomalous blue-shift is more than a peculiar curiosity. The experiments are performed in the terahertz (THz) frequency range with coherent continuous-wave spectroscopy. The results establish dielectric and metallic tuning as a novel, and viable approach to tune high quality (high-Q) WGMs, and provide valuable insights into the anomalous blue-shift of WGM cavity systems. The tuning capabilities for these compact monolithic resonators is of significant interest for fundamental science and technological applications alike.

description: In this paper, a model for a spatial network evolution based on a Metropolis simulation is presented. The model uses an energy function that depends both on the distance between the nodes and the stated preferences. The agents influence their network neighbors opinions using the CODA model. That means each agent has a preference between two options based on its probabilistic assessment of which option is the best one. The algorithm generates realistic networks for opinion problems as well as temporal dynamics for those networks. The transition from a random state to an ordered situation, as temperature decreases, is described. Different types of networks appear based on the relative strength of the spatial and opinion components of the energy.

description: This paper compares classical copying and quantum entanglement in natural language by considering the case of verb phrase (VP) ellipsis. VP ellipsis is a non-linear linguistic phenomenon that requires the reuse of resources, making it the ideal test case for a comparative study of different copying behaviours in compositional models of natural language. Following the line of research in compositional distributional semantics set out by (Coecke et al., 2010) we develop an extension of the Lambek calculus which admits a controlled form of contraction to deal with the copying of linguistic resources. We then develop two different compositional models of distributional meaning for this calculus. In the first model, we follow the categorical approach of (Coecke et al., 2013) in which a functorial passage sends the proofs of the grammar to linear maps on vector spaces and we use Frobenius algebras to allow for copying. In the second case, we follow the more traditional approach that one finds in categorial grammars, whereby an intermediate step interprets proofs as non-linear lambda terms, using multiple variable occurrences that model classical copying. As a case study, we apply the models to derive different readings of ambiguous elliptical phrases and compare the analyses that each model provides.

description: A FRWL cosmological model with perfect fluid comprising of van der Waals gas and dust has been studied in the context of dynamical analysis of a three-component autonomous non-linear dynamical system for the particle number density $n$, the Hubble parameter $H$, and the temperature $T$. Perfect fluid isentropic particle creation at rate proportional to an integer power $α$ of $H$ has been incorporated. The existence of a global first integral allows the determination of the temperature evolution law and hence the reduction of the dynamical system to a two-component one. Special attention is paid to the cases of $α= 2$ and $α= 4$ and these are illustrated with numerical examples. The global dynamics is comprehensively studied for different choices of the values of the physical parameters of the model. Trajectories in the $(n, H)$ phase space are identified for which temporary inflationary regime exists.

description: Categorical compositional distributional semantics provide a method to derive the meaning of a sentence from the meaning of its individual words: the grammatical reduction of a sentence automatically induces a linear map for composing the word vectors obtained from distributional semantics. In this paper, we extend this passage from word-to-sentence to sentence-to-discourse composition. To achieve this we introduce a notion of basic anaphoric discourses as a mid-level representation between natural language discourse formalised in terms of basic discourse representation structures (DRS); and knowledge base queries over the Semantic Web as described by basic graph patterns in the Resource Description Framework (RDF). This provides a high-level specification for compositional algorithms for question answering and anaphora resolution, and allows us to give a picture of natural language understanding as a process involving both statistical and logical resources.

description: Early detection of cancer is crucial for treatment and overall patient survival. In the upper aerodigestive tract (UADT) the gold standard for identification of malignant tissue is an invasive biopsy. Recently, non-invasive imaging techniques such as confocal laser microscopy and optical coherence tomography (OCT) have been used for tissue assessment. In particular, in a recent study experts classified lesions in the UADT with respect to their invasiveness using OCT images only. As the results were promising, automatic classification of lesions might be feasible which could assist experts in their decision making. Therefore, we address the problem of automatic lesion classification from OCT images. This task is very challenging as the available dataset is extremely small and the data quality is limited. However, as similar issues are typical in many clinical scenarios we study to what extent deep learning approaches can still be trained and used for decision support.

description: The physics governing electron acceleration by a relativistically intense laser are not confined to the critical density surface, they also pervade the sub-critical plasma in front of the target. Here, particles can gain many times the ponderomotive energy from the overlying laser, and strong fields can grow. Experiments using a high contrast laser and a prescribed laser pre-pulse demonstrate that development of the pre-plasma has an unexpectedly strong effect on the most energetic, super-ponderomotive electrons. Presented 2D particle-in-cell simulations reveal how strong, voluminous magnetic structures that evolve in the pre-plasma impact high energy electrons more significantly than low energy ones for longer pulse durations and how the common practice of tilting the target to a modest incidence angle can be enough to initiate strong deflection. The implications are that multiple angular spectral measurements are necessary to prevent misleading conclusions from past and future experiments.

description: This study investigated the genomic characteristics of Acheta domesticus volvovirus (AdVVV) in a commercial cricket farming operation. BLAST analysis of the Acheta domesticus genome assembly identified sequences with high similarity to the AdVVV-Japan genome, suggesting AdVVV presence. PCR confirmed AdVVV infection in the A. domesticus breeding population from Nakhon Ratchasima farm, Thailand. The complete 2,516 nucleotide AdVVV-Thailand genome was reconstructed through targeted primer amplification and sequencing. It contained four open reading frames encoding hypothetical proteins, with a characteristic hairpin structure at the termini, consistent with other AdVVV isolates. Phylogenetic analysis revealed AdVVV-Thailand's closer genetic affiliation with AdVVV-Japan compared to other isolates. Comparative analysis of coding sequences across five AdVVV isolates showed the highest variability in the hypothetical protein/putative capsid protein ORF1, with 64 variable sites out of 1086 bases, suggesting its significance in genetic diversity. In contrast, ORF2, ORF3, and ORF4 exhibited minimal variability. The majority of variations were singletons, with 85.33% confined to ORF1. This study confirmed AdVVV presence in a commercial cricket farm, reconstructed the AdVVV-Thailand genome, provided insights into its phylogeny and genetic diversity across isolates, highlighting the putative capsid protein's role in driving variability. These findings enhance understanding of AdVVV genomics and evolutionary dynamics within cricket populations.

description: In recent years, machine learning techniques have been increasingly applied in sensitive decision making processes, raising fairness concerns. Past research has shown that machine learning may reproduce and even exacerbate human bias due to biased training data or flawed model assumptions, and thus may lead to discriminatory actions. To counteract such biased models, researchers have proposed multiple mathematical definitions of fairness according to which classifiers can be optimized. However, it has also been shown that the outcomes generated by some fairness notions may be unsatisfactory. In this contribution, we add to this research by considering decision making processes in time. We establish a theoretic model in which even perfectly accurate classifiers which adhere to almost all common fairness definitions lead to stable long-term inequalities due to vicious cycles. Only demographic parity, which enforces equal rates of positive decisions across groups, avoids these effects and establishes a virtuous cycle, which leads to perfectly accurate and fair classification in the long term.

description: The combined chemotherapy and photodynamic therapy have significant advantages for cancer treatments, which have higher therapeutic effects compared with other medicines. Herein, we focused on the synthesis of carbon quantum dot (CQD) based nanocarrier system. CQD and 5-aminolevulinic acid (5-ALA) were conjugated with mono-(5-BOC-protected-glutamine-6-deoxy) β-cyclodextrin (CQD-Glu-β-CD) moiety, and finally, the anticancer chemotherapy doxorubicin (DOX) drug was loaded in the 5-ALA-CQD-Glu-β-CD system. The stepwise physicochemical changes for the preparation of the DOX loaded 5-ALA-CQD-Glu-β-CD system were investigated by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic force microscopy (AFM), and Raman fluorescence spectroscopy. The encapsulation efficiency of DOX in 5-ALA-CQD-Glu-β-CD was observed at ∼83.0%, and the loading capacity of DOX is ∼20.37%. The in vitro releasing of DOX and 5-ALA was observed through the UV–vis spectroscopy by the λmax value of 487 nm and 253 nm, respectively. By the investigation against the breast MCF-7 cancer cells, the high cytotoxicity and morphological changes of cancer cells were observed by the treating of DOX/5-ALA-CQD-Glu-β-CD. The generation of reactive oxygen species (ROS) upon 635 nm (25 mW cm−2) for 15 min laser irradiation-induced improved the therapeutic effects. In vitro cellular uptake studies recommend the synthesized DOX/5-ALA-CQD-Glu-β-CD nanocarrier could significantly enhance the cell apoptosis and assist in the MCF-7 cell damages. The result suggests a multifunctional therapeutic system for chemo/photodynamic synergistic effects on cancer therapy.

description: We present the full form of a four-point correlation function of large BPS operators in planar N = 4 Super Yang-Mills to any loop order. We do this by following a bootstrap philosophy based on three simple axioms pertaining to (i) the space of functions arising at each loop order, (ii) the behaviour in the OPE in a double-trace dominated channel and (iii) the behaviour under a double null limit. We discuss how these bootstrap axioms are in turn strongly motivated by empirical observations up to nine loops unveiled through integrability methods in our previous work [9] on this simplest correlation function.

description: This study emphasizes the interaction between subjective social class and sex, aims to identify which groups have deficient emotion recognition ability, and explores the underlying psychological mechanisms. Two studies using a self-developed Chinese facial emotion recognition task provide support for the interaction between subjective social class and sex in emotion recognition (Studies 1 and 2), and the mediating role of dominance (Study 2). Specifically, only males in a subjectively higher social class tend to be dominant, resulting in lower emotion recognition ability, whereas females did not show differences in dominance strategy preference and emotion recognition ability related to subjective social class. Moreover, these findings apply not only to students but also to working people with social experience. These studies help to improve mutual understanding and provide insights and guidance for forming good human interactions.

description: Dalla scultura funeraria egizia alle statue greche, dai marmi di Michelangelo ai torsi di Rodin, dalle Muse Addormentate di Brâncuși alle sculture antropomorfe di Hans Arp, il protagonista della scultura è sempre stato il corpo – trasfigurato, idealizzato, alterato, ma sempre corpo, sempre quest’architettura tutta umana di sangue e muscoli. Eppure, nel lavoro di Doris Salcedo (Bogotá, 1958) è pro-prio il corpo il grande assente: nelle sue opere l’artista colombiana rielabora l’esperienza delle vittime della guerra civile, concentrandosi in particolare sui desaparecidos, individui sequestrati dalle diverse forme di potere in atto in Colombia e mai più ritrovati, individui la cui esistenza è stata, letteralmente e figurativamente, cancellata. Ricombinando mobili, vestiti ed effetti appartenuti ai desaparecidos, Salcedo intende rappresentare sia l’esperienza di queste vittime “scomparse”, sia il trauma vissuto dai loro familiari, bloccati in un quella che Freud ha definito “condizione melanconica” poiché, in assenza del corpo amato, il lavoro del lutto diviene un processo interminabile. Rielaborando un vasto universo di riferimenti – dalle riflessioni sulla violenza proposte da Agamben e Nancy, fino alle sperimentazioni spaziali di Duchamp, Beuys, Nauman e Smithson – Salcedo dà vita a una poetica originale, dove gli oggetti divengono i preziosi testimoni delle nostre esistenze. E se da un lato riesce a redimere le vittime dalla loro anonimità, dall’altro ci pone la più inquieta delle domande: che cosa rimane di noi individui quando la vita svanisce.

description: This paper is concerned with the long time behavior of Langevin dynamics of {\em Coulomb gases} in $\mathbf{R}^d$ with $d\geq 2$, that is a second order system of Brownian particles driven by an external force and a pairwise repulsive Coulomb force. We prove that the system converges exponentially to the unique Boltzmann-Gibbs invariant measure under a weighted total variation distance. The proof relies on a novel construction of Lyapunov function for the Coulomb system.

description: Carotid atherosclerosis is a focal disease at the bifurcations of the carotid artery. To quantitatively monitor the local changes in the vessel-wall-plus-plaque thickness (VWT) and compare the VWT distributions for different patients or for the same patients at different ultrasound scanning sessions, a mapping technique is required to adjust for the geometric variability of different carotid artery models. In this work, we propose a novel method called density-equalizing reference map (DERM) for mapping 3D carotid surfaces to a standardized 2D carotid template, with an emphasis on preserving the local geometry of the carotid surface by minimizing the local area distortion. The initial map was generated by a previously described arc-length scaling (ALS) mapping method, which projects a 3D carotid surface onto a 2D non-convex L-shaped domain. A smooth and area-preserving flattened map was subsequently constructed by deforming the ALS map using the proposed algorithm that combines the density-equalizing map and the reference map techniques. This combination allows, for the first time, one-to-one mapping from a 3D surface to a standardized non-convex planar domain in an area-preserving manner. Evaluations using 20 carotid surface models show that the proposed method reduced the area distortion of the flattening maps by over 80% as compared to the ALS mapping method.

description: A wide variety of applications of microwave cavities, such as measurement and control of superconducting qubits, magnonic resonators, and phase noise filters, would be well served by having a highly tunable microwave resonance. Often this tunability is desired in situ at low temperatures, where one can take advantage of superconducting cavities. To date, such cryogenic tuning while maintaining a high quality factor has been limited to $\sim500$ MHz. Here we demonstrate a three-dimensional superconducting microwave cavity that shares one wall with a pressurized volume of helium. Upon pressurization of the helium chamber the microwave cavity is deformed, which results in in situ tuning of its resonant frequency by more than 5 GHz, greater than 60% of the original 8 GHz resonant frequency. The quality factor of the cavity remains approximately constant at $\approx7\times 10^{3}$ over the entire range of tuning. As a demonstration of its usefulness, we implement a tunable cryogenic phase noise filter, which reduces the phase noise of our source by approximately 10 dB above 400 kHz.

description: The kappa-distributed fully ionized plasma with collisional interaction is investigated. The Fokker-Planck equation with Rosenbluth potential is employed to describe such a physical system. The results show that the kappa distribution is not a stationary distribution unless the parameter kappa tends to infinity. The general expressions of collisional relaxation rate of multiple-component plasma with kappa distribution are derived and discussed in specific cases in details. For the purpose of visual illustration, we also give those results numerically in figures. All the results show that the parameter kappa plays a significant role in relaxation rate.

description: It is well accepted that a magnetic flux rope (MFR) is a critical component of many coronal mass ejections (CMEs), yet how it evolves toward eruption remains unclear. Here we investigate the continuous evolution of a pre-existing MFR, which is rooted in strong photospheric magnetic fields and electric currents. The evolution of the MFR is observed by the Solar Terrestrial Relations Observatory (STEREO) and the Solar Dynamics Observatory (SDO) from multiple viewpoints. From STEREO's perspective, the MFR starts to rise slowly above the limb five hours before it erupts as a halo CME on 2012 June 14. In SDO observations, conjugate dimmings develop on the disk, simultaneously with the gradual expansion of the MFR, suggesting that the dimmings map the MFR's feet. The evolution comprises a two-stage gradual expansion followed by another stage of rapid acceleration/eruption. Quantitative measurements indicate that magnetic twist of the MFR increases from 1.0 +/- 0.5 to 2.0 +/- 0.5 turns during the five-hour expansion, and further increases to about 4.0 turns per AU when detected as a magnetic cloud at 1 AU two day later. In addition, each stage is preceded by flare(s), implying reconnection is actively involved in the evolution and eruption of the MFR. The implications of these measurements on the CME initiation mechanisms are discussed.

description: Aim: Narrative medicine has been promoted as an innovative and effective means of stimulating medical students’ professional development by teaching them to approach their patients’ experiences of illness with more understanding and compassion. This systematic literature review aims to answer the following question: what evidence of effect is available in the literature about models for teaching narrative medicine? Methods: We conducted a narrative review of 36 articles and used the Best Evidence in Medical Education (BEME) Global Scale and Kirkpatrick Scale for strength and importance of evidence to categorize reported assessment strategies and to evaluate the effectiveness of their narrative medicine programs. Results: We found evidence that narrative medicine is an effective pedagogic tool with a clear and replicable structure and methodology. We also determined that a positive impact could be measured when pertaining to participation and modification of attitudes, knowledge, and skills. However, unequivocal evidence of the effect of narrative medicine on students’ behavior or ongoing interaction with colleagues and patients is still lacking. Conclusion: While many recent publications describe the goals and virtues of a narrative-based approach, more research is needed to determine whether or not there is an ideological consensus undergirding this approach. In addition, it is still unclear whether the long-term impact of narrative medicine classroom interventions are felt by patients, or whether such interventions positively impact patient care.

description: This paper discusses predictive inference and feature selection for generalized linear models with scarce but high-dimensional data. We argue that in many cases one can benefit from a decision theoretically justified two-stage approach: first, construct a possibly non-sparse model that predicts well, and then find a minimal subset of features that characterize the predictions. The model built in the first step is referred to as the \emph{reference model} and the operation during the latter step as predictive \emph{projection}. The key characteristic of this approach is that it finds an excellent tradeoff between sparsity and predictive accuracy, and the gain comes from utilizing all available information including prior and that coming from the left out features. We review several methods that follow this principle and provide novel methodological contributions. We present a new projection technique that unifies two existing techniques and is both accurate and fast to compute. We also propose a way of evaluating the feature selection process using fast leave-one-out cross-validation that allows for easy and intuitive model size selection. Furthermore, we prove a theorem that helps to understand the conditions under which the projective approach could be beneficial. The benefits are illustrated via several simulated and real world examples.

description: In this research paper, we have used lean tools that are applicable in various faster growingindustries like FMCG, pharmaceuticals; hospitality, manufacturing etc are used. The tool that is given the priority over others in identifying the waste is Value stream mapping. Value stream mapping is a lean tool that is used to translate both information and flow of data through which those processes that are not adding any positive value in our study can be easily eliminated. This paper is an effective effort to find out the waste production during manufacturing of a perishable goods in discrete manufacturing system. Pareto chart has been used to categories the factors that are responsible forthe 80 percent of waste. Here Ishikawa diagram has played a vital role for finding of their possible causes and effect. Other contemporary lean tools like Kanban, Kaizen, and FIFO are used for future state map processing. The resultobtained through the future state value stream map states the changeover time of various processes, the cycle time near to the takt time, improvement in lead time and total cycle time of the manufacturing process

description: Using ensembles of two, three and four spheres immersed in a fermionic background we evaluate the (integrated) density of states and the Casimir energy. We thus infer that for sufficiently smooth objects, whose various geometric characteristic lengths are larger then the Fermi wave length one can use the simplest semiclassical approximation (the contribution due shortest periodic orbits only) to evaluate the Casimir energy. We also show that the Casimir energy for several objects can be represented fairly accurately as a sum of pairwise Casimir interactions between pairs of objects.

description: It is argued that there is no low-energy resonance associated with the pi-operators introduced by Demler and Zhang. This implies that the Hubbard model does not possess an approximate SO(5) symmetry generated by these operators. Recent finite-size studies are re-interpreted accordingly.
