Label-free second-harmonic phase imaging of biological specimen by digital holographic microscopy (2010)

We have previously developed a new way for nonscanning second-harmonic generation (SHG) microscopy [Opt. Lett. 34, 2450 (2009)]. Based on digital holography, this technique captures, in single-shot hologram acquisition, both the amplitude and the phase of a coherent SHG radiation, which makes possible second harmonic phase microscopy. In this work, we present holographic SHG phase microscopy of a label-free biological tissue and discuss its added value to SHG microscopy.
Design of Cross-Linked Starch Nanocapsules for Enzyme-Triggered Release of Hydrophilic Compounds (2017)

Cross-linked starch nanocapsules (NCs) were synthesized by interfacial polymerization carried out using the inverse mini-emulsion technique. 2,4-toluene diisocyanate (TDI) was used as the cross-linker. The influence of TDI concentrations on the polymeric shell, particle size, and encapsulation efficiency of a hydrophilic dye, sulforhodamine 101 (SR 101), was investigated by Fourier transform infrared (FT-IR) spectroscopy, dynamic light scattering (DLS), and fluorescence measurements, respectively. The final NC morphology was confirmed by scanning electron microscopy. The leakage of SR 101 through the shell of NCs was monitored at 37 °C for seven days, and afterwards the NCs were redispersed in water. Depending on cross-linker content, permeable and impermeable NCs shell could be designed. Enzyme-triggered release of SR 101 through impermeable NC shells was investigated using UV spectroscopy with different α-amylase concentrations. Impermeable NCs shell were able to release their cargo upon addition of amylase, being suitable for a drug delivery system of hydrophilic compounds.
A novel optoelectronic ferrule and easy ribbon fiber splicer for cost-effective optical interconnection (2006)

Attention has turned in recent years to optical interconnection as the most cost-effective solution to the problem of I/O bottlenecks in the wiring of conventional FR4 printed wiring boards. In this paper we propose a new configuration for the key element in realizing optical interconnections, a low-cost electrical/optical (E/O) converter module. We furthermore propose an easy splicer and a ribbonized coated-mountable fiber for multicore optical interconnections.
Broadband electronically tunablemicrostrip ring resonator filterwith negative resistance coupling (1996)

Broadband electronically tunable filters can be realised using varactor tuned ring resonators with negative resistance coupling. Broadband matching circuits must be used for negative resistance realisation and for compensating the input and output impedance variation with frequency. Circuits and simulated results for a two section 1.3 to 2.1 GHz silicon varactor tuned 50 to 70 MHz bandwidth ring resonator filter are presented.
Plasma immunadsorption treatment in patients with primary focal and segmental glomerulosclerosis (1998)

We conclude that a positive GVV-test before treatment makes a favourable response of IAT on proteinuria likely in patients with FSGS. If a reduction of proteinuria can be obtained by IAT this is due to an improvement in glomerular size and/or charge selectivity.
Location errors in wireless embedded sensor networks (2002)

Wireless sensor networks monitor the physical world by taking measurements of physical phenomena. Those measurements, and consequently the results computed from the measurements, may be significantly inaccurate. Therefore, in order to properly design and use wireless sensor networks, one must develop methods that take error sources, error propagation through optimization software, and ultimately their impact on applications, into consideration. In this paper, we focus on location discovery induced errors. We have selected location discovery as the object of our case study since essentially all sensor network computation and communication tasks are dependent on geographical node location data. First, we model the error in input parameters of the location discovery process. Then, we study the impact of errors on three selected applications: exposure, best- and worst-case coverage, and shortest path routing. Furthermore, we examine how the choice of a specific objective function optimized during the location discovery process impacts the errors in results of different applications.
Chemical Imaging of Buried Interfaces in Organic–Inorganic Devices Using Focused Ion Beam-Time-of-Flight-Secondary-Ion Mass Spectrometry (2019)

Organic-inorganic hybrid materials enable the design and fabrication of new materials with enhanced properties. The interface between the organic and inorganic materials is often critical to the device's performance; therefore, chemical characterization is of significant interest. Because the interfaces are often buried, milling by focused ion beams (FIBs) to expose the interface is becoming increasingly popular. Chemical imaging can subsequently be obtained using secondary-ion mass spectrometry (SIMS). However, the FIB milling process damages the organic material. In this study, we make an organic-inorganic test structure to develop a detailed understanding of the processes involved in FIB milling and SIMS imaging. We provide an analysis methodology that involves a "clean-up" process using sputtering with an argon gas cluster ion source to remove the FIB-induced damage. The methodology is evaluated for two additive manufactured devices, an encapsulated strain sensor containing silver tracks embedded in a polymeric material and a copper track on a flexible polymeric substrate created using a novel nanoparticle sintering technique.
Analysis of proteins and peptides on a chromatographic timescale by electron‐transfer dissociation MS (2007)

Peptide and protein sequence analysis using a combination of gas-phase ion-ion chemistry and tandem MS is described. Samples are converted to multiply charged ions by ESI and then allowed to react with fluoranthene radical anions in a quadrupole linear ion trap mass spectrometer. Electron transfer from the radical anion to the multiply charged peptide or protein promotes random fragmentation along the amide backbone that is independent of peptide or protein size, sequence, or the presence of post-translational modifications. Examples are provided that demonstrate the utility of electron-transfer dissociation for characterizing post-translational modifications and for identifying proteins in mixtures on a chromatographic timescale (500 ms/protein).
Strain-assisted magnetization reversal in Co/Ni multilayers with perpendicular magnetic anisotropy (2016)

Multifunctional materials composed of ultrathin magnetic films with perpendicular magnetic anisotropy combined with ferroelectric substrates represent a new approach toward low power, fast, high density spintronics. Here we demonstrate Co/Ni multilayered films with tunable saturation magnetization and perpendicular anisotropy grown directly on ferroelectric PZT [Pb(Zr0.52Ti0.48)O3] substrate plates. Electric fields up to ±2 MV/m expand the PZT by 0.1% and generate at least 0.02% in-plane compression in the Co/Ni multilayered film. Modifying the strain with a voltage can reduce the coercive field by over 30%. We also demonstrate that alternating in-plane tensile and compressive strains (less than 0.01%) can be used to propagate magnetic domain walls. This ability to manipulate high anisotropy magnetic thin films could prove useful for lowering the switching energy for magnetic elements in future voltage-controlled spintronic devices.
A Framework for an End-to-End Secure Wireless Smart Home System (2008)

This paper describes a complete framework for an end- to-end smart home monitoring and control system. The communication with all components of the system is done using a variety of wireless technologies. The system incorporates security features at both ends that prevent unauthorized access as well as assign privileges to the users. The complete prototype smart home system was implemented and it supports three main services: monitoring the status of devices, controlling their settings through configurations that are device dependent, and periodic notification of the status of devices. The prototype system has a modular structure that enables the incorporation of additional components and services.
Safety profiles of terahertz scanning in ophthalmology (2021)

Terahertz (THz) technology has emerged recently as a potential novel imaging modality in biomedical fields, including ophthalmology. However, the ocular biological responses after THz electromagnetic exposure have not been investigated. We conducted a rabbit study to evaluate the safety profiles of THz scanning on eyes, at a tissue, cellular, structural and functional level. Eight animals (16 eyes) were analysed after excessive THz exposure (control, 1 h, 4 h, and 1 week after continuous 4-h exposure; THz frequency = 0.3 THz with continuous pulse generated at 40 µW). We found that at all the time points, the corneas and lens remained clear with no corneal haze or lens opacity formation clinically and histopathologically. No thermal effect, assessed by thermographer, was observed. The rod and cone cell-mediated electroretinography responses were not significantly altered, and the corneal keratocytes activity as well as endothelial viability, assessed by in-vivo confocal microscopy, was not affected. Post-exposed corneas, lens and retinas exhibited no significant changes in the mRNA expression of heat shock protein (HSP)90AB1), DNA damage inducible transcript 3 (DDIT3), and early growth response (EGR)1. These tissues were also negative for the inflammatory (CD11b), fibrotic (fibronectin and α-smooth muscle actin), stress (HSP-47) and apoptotic (TUNEL assay) responses on the immunohistochemical analyses. The optical transmittance of corneas did not change significantly, and the inter-fibrillar distances of the corneal stroma evaluated with transmission electron microscopy were not significantly altered after THz exposure. These results provide the basis for future research work on the development of THz imaging system for its application in ophthalmology.
An Investigation in Improving the Exhaust Management Process on Miller Cycle and Turbocompounding (2012)

A reduction in diesel engine fuel consumption at a constant emissions level can be achieved by various means. A power turbine as a means of waste heat recovery (i.e., turbocompounding) and altered intake valve closure timing (Miller cycle) are two such mechanisms. Each of these technologies act as a means of improving the expansion process of the combustion gases, requiring reduced fueling for the same work extraction. When these embodiments are typically implemented, the timing of the exhaust valve opening is maintained. However, optimization of the timing of the exhaust valve opening presents the potential for further improvement in the expansion process. Variations in the exhaust valve opening timing will be investigated for Miller and turbocompounding cycles as well as the combination of the two features. Results will be shown to quantify the impact these variations have in system efficiency. Second law analysis will be used to show how these variations in engine configurations impact individual loss mechanisms. Finally, comparisons will be made to show the relative differences between Miller cycle and turbocompounding with and without optimization of the exhaust valve timing.
Subclinical depressive symptoms during late midlife and structural brain alterations: A longitudinal study of Danish men born in 1953 (2018)

We explored whether depressive symptoms measured three times during midlife were associated with structural brain alterations quantified using magnetic resonance imaging measurements of volume, cortical thickness, and intensity texture. In 192 men born in 1953 with depressive symptoms measured at age 51, 56, and 59 years, magnetic resonance imaging was performed at age 59. All data processing was performed using the Freesurfer software package except for the texture-scores that were computed using in-house software. Structural brain alterations and associations between depressive symptoms and brain structure outcomes were tested using Pearson's correlation, t test, and linear regression. Depressive symptoms at age 51 showed clear inverse correlations with total gray matter, pallidum, and hippocampal volume with the strongest estimate for hippocampal volume (r = -.22, p < .01). After exclusion of men (n = 3) with scores in the range of clinical depression the inverse correlation between depressive symptoms and hippocampal volume became insignificant (r = -13, p = .08). Depressive symptoms at age 59 correlated positively with hippocampal and amygdala texture-potential early markers of atrophy. Inverse relations with total gray matter and pallidum volumes lost significance when the analysis was adjusted for intracranial volume. In men, depressive symptoms at age 51 were associated with a reduced volume of the hippocampus at age 59 independent of later symptoms. Amygdala and hippocampal textures might be the early markers for brain alterations associated with depression in midlife.
Morphology development in single drop drying for native and aggregated whey protein dispersions (2019)

Native and aggregated whey proteins (WP) are used in food and pharmaceutical applications as stabilizers, thickeners and carriers. For increasing shelf-life and facilitating transportation, WP are transformed into powders by spray-drying. Powder functional properties strongly depend on the final particle morphology. Focusing on colloidal aspects of drying, the goal of this work is to: (i) investigate morphology development during single drop drying of native and aggregated whey protein dispersions; (ii) use structure-mechanical parameters to predict the final morphology. Results showed evaporation rate and morphology development characteristic times are not affected significantly by colloidal size. However, the final morphology of particles depends on WP colloidal size. For small colloids, particles are shriveled, while their shape is cup-like for larger colloids. Structure–mechanical parameters allowed predicting a buckled/shriveled morphology in agreement with experimental observations. Specifically, predictions anticipated the formation of a solid shell at the particle surface, which is compressed during drying, as a result of colloidal interactions being dominated by van der Waals forces. This work provides a rationalization of morphology development of WP particles. In addition, the work suggests that the elastic – or gel – formation, that is governed by the permeation, may be very different depending on the permeability of the proteins gel. The collapse from a dispersion to an elastic gel may be responsible for the shriveled to buckled transition. The work shows that diverse final morphologies can be achieved using same drying conditions and composition, while only changing the degree of colloidal aggregation.
Sketch Interpretation and Refinement Using Statistical Models (2004)

We present a system for generating 2D illustrations from hand drawn outlines consisting of only curve strokes. A user can draw a coarse sketch and the system would automatically augment the shape, thickness, color and surrounding texture of the curves making up the sketch. The styles for these refinements are learned from examples whose semantics have been pre-classified. There can be several styles applicable on a curve and the system automatically identifies which one to use and how to use it based on a curve's shape and its context in the illustration. Our approach is based on a Hierarchical Hidden Markov Model. We present a two level hierarchy in which the refinement process is applied at: the curve level and the scene level.

3D AFM Characterization of the Edge Roughness of Silicon High Q Resonators (2010)

Nanophotonic resonators are very sensitive to sidewall roughness. We investigate in detail the sidewall roughness, correlation length and fractal roughness exponent for high Q silicon resonators using a 3D AFM
Multi-Realism Image Compression with a Conditional Generator (2022)

By optimizing the rate-distortion-realism trade-off, generative compression approaches produce detailed, realistic images, even at low bit rates, instead of the blurry reconstructions produced by rate-distortion optimized models. However, previous methods do not explicitly control how much detail is synthesized, which results in a common criticism of these methods: users might be worried that a misleading reconstruction far from the input image is generated. In this work, we alleviate these concerns by training a decoder that can bridge the two regimes and navigate the distortion-realism trade-off. From a single compressed representation, the receiver can decide to either reconstruct a low mean squared error reconstruction that is close to the input, a realistic reconstruction with high perceptual quality, or anything in between. With our method, we set a new state-of-the-art in distortion-realism, pushing the frontier of achievable distortion-realism pairs, i.e., our method achieves better distortions at high realism and better realism at low distortion than ever before.
Single-cell atlas of tumor clonal evolution in liver cancer (2020)

SUMMARY Tumor evolution is a key feature of tumorigenesis and plays a pivotal role in driving intratumor heterogeneity, treatment failure and patients’ prognosis. Here we performed single-cell transcriptome profiling of 46 primary liver cancers from 37 patients enrolled for interventional studies. We surveyed the landscape of ~57,000 malignant and non-malignant cells and determined tumor cell clonality by developing a machine learning-based consensus clustering method. We found evidence of tumor cell branching evolution using hierarchical clustering, RNA velocity as well as reverse graph embedding methods. Interestingly, an increasing tumor cell clonality was tightly linked to patients’ prognosis, accompanied by a polarized immune cell landscape. We identified osteopontin as a key player for tumor cell evolution and microenvironmental reprogramming. Our study offers insight into the collective behavior of tumor cell communities in liver cancer as well as potential drivers for tumor evolution in response to therapy.
Evolution of IgM, IgE and IgG1-4antibody responses in early childhood monitored with recombinant allergen components: implications for class switch mechanisms (2002)

The formation of IgE antibodies against environmental allergens represents the hallmark of type I allergy. Data from in vitro cultured cells and experimental animal models provide controversial evidence for isotype switching from IgM to IgE production via sequential as well as non-sequential (i.e. direct) class switch. We analyzed the evolution of IgE responses in 11 children developing birch pollen and/or grass pollen allergy during the first 7 years of life using purified recombinant allergen molecules (major birch pollen allergen, Bet v 1; major timothy grass pollen allergens, Phl p 1, Phl p 2, Phl p 5). Demographic, clinical and serological data indicated a postnatal sensitization to pollen allergens. A parallel development of IgG(1-4) and IgE responses to recombinant allergen molecules compatible with a strictly sequential class switch to IgE was observed only in one child. The only partly synchronized and dissociated development of allergen-specific antibody responses found in all other cases can be best explained by a partly sequential class switch involving few switch stations or, more likely, by direct class switching. Kinetics and courses of allergen-specific antibody responses (IgM, IgG(1-4), IgE) during the first years of life suggest that, once established, allergen-specific IgE responses are driven by antigen contact rather than by cytokines controlling class switch to IgE.
<title>Nonlinear frequency converters as sources and detectors of polarized light with linear polarization degree of 10-9</title> (1992)

High degrees of linear polarization of laser radiation and sensitivity to its variation are achieved by applying frequency converters using nonlinear crystals as polarizers and analyzers. The factors leading to distortion of linear polarization of light in such devices are identified. A KD<SUP>*</SUP>P polarimeter with extinction ratio of 5 (DOT) 10<SUP>-9</SUP> is developed on the basis of a quasi-CW picosecond YAG laser.

Reversible and irreversible polarization processes in ferroelectric ceramics and thin films (2003)

In this article, the separation between reversible and irreversible polarization where the reversible polarization component is determined by capacitance–voltage curve measurements, is used to characterize ferroelectric materials. After giving a thorough foundation of the method, it is used to investigate the influence of the composition on the reversible and irreversible polarization contributions in ferroelectric thin films and/or bulk ceramics. The reversible polarization is also monitored during fatigue. A comparison to bulk ceramics suggests that the domain wall motion in ferroelectric thin films is reduced compared to bulk ceramics.
