Nonlinear Oscillators in Space Physics (2011)

We discuss dynamical systems that produce an oscillation without an external time dependent source. Numerical results are presented for nonlinear oscillators in the Em1h's atmosphere, foremost the quasi-biennial oscillation (QBOl. These fluid dynamical oscillators, like the solar dynamo, have in common that one of the variables in a governing equation is strongly nonlinear and that the nonlinearity, to first order, has particular form. of 3rd or odd power. It is shown that this form of nonlinearity can produce the fundamental li'equency of the internal oscillation. which has a period that is favored by the dynamical condition of the fluid. The fundamental frequency maintains the oscillation, with no energy input to the system at that particular frequency. Nonlinearities of 2nd or even power could not maintain the oscillation.
Efficient mobility and traffic management for delay tolerant cloud data in 5G networks (2015)

The explosive growth of the demand for higher data rates in mobile networks have been mainly driven by the increasing use of cloud based applications by smartphones. This has led the industry to investigate new radio access technologies to be deployed as part of 5G networks, while providing mechanisms to manage user mobility and traffic in a more efficient manner. In this paper, we consider a mobility and traffic management mechanism that proposes a close interaction between the cloud data servers and the radio access network to enable efficient network operation. Such a management mechanism is enabled by utilizing the application-dependent delay tolerance properties of the cloud data, with the delay values conveyed to the radio access network and UE to manage the service requests for the cloud data. The mechanism was evaluated using LTE-Advanced heterogeneous network scenario and 5G dense-urban information society scenario from EU FP7 METIS project, and relative gains in terms of packet delays and throughput values are presented. The results indicate significant gains using the proposed management mechanism as compared to the reference case where no such enhancements are used.
Joint Mobility-Aware UAV Placement and Routing in Multi-Hop UAV Relaying\n Systems (2020)

Unmanned Aerial Vehicles (UAVs) have been extensively utilized to provide\nwireless connectivity in rural and under-developed areas, enhance network\ncapacity and provide support for peaks or unexpected surges in user demand,\nmainly due to their fast deployment, cost-efficiency and superior communication\nperformance resulting from Line of Sight (LoS)-dominated wireless channels. In\norder to exploit the benefits of UAVs as base stations or relays in a mobile\nnetwork, a major challenge is to determine the optimal UAV placement and\nrelocation strategy with respect to the mobility and traffic patterns of the\nground network nodes. Moreover, considering that the UAVs form a multi-hop\naerial network, capacity and connectivity constraints have significant impacts\non the end-to-end network performance. To this end, we formulate the joint UAV\nplacement and routing problem as a Mixed Integer Linear Program (MILP) and\npropose an approximation that leads to a LP rounding algorithm and achieves a\nbalance between time-complexity and optimality.\n
A Full-Digital Multi-Channel CMOS Capacitive Sensor (2006)

A full-digital 12-channel, 100-step capacitive sensor is described. The capacitance to be sensed forms an RC-delay line whose delay is compared with that of a reference RC-delay line. The difference of the RC delays is sensed by a simple full-digital time-to-digital converter (TDC). By compensating the parasitic capacitance at power up, the capacitive sensor implemented in a 0.35 mum standard digital CMOS technology shows 30fF sensing resolution. The capacitive sensor consumes 5 muA per channel under 3.3V supply voltage.
An electrothermal PIN diode model with substrate injection (2014)

This paper presents a compact model for an integrated 3-terminal PIN diode suitable for SPICE simulation. The model described within represents a significant extension to the standard 2-terminal diode model of SPICE, capturing phenomena critical to the accurate prediction of diode behavior in modern integrated process technologies. In particular, the inclusion of self-consistent electrothermal modeling and substrate injection effects is key to improving simulation accuracy for diodes operating in a forward conductive state, such as would be common for PIN diodes. The model is implemented in Verilog-A and hardware-verified results are presented for a 90nm SiGe BiCMOS technology featuring a high-performance integrated PIN diode.
Postmortem Findings in Two Patients with the Carbohydrate‐deficient Glycoprotein Syndrome (1991)

The postmortem findings in a pair of twins with the carbohydrate‐deficient glycoprotein syndrome are reported. Rapidly progressive olivopontocerebellar atrophy associated with retinopathy, were the most significant findings within the central nervous system. Additional observations were cerebral infarction, evidence of immune deficiency, steatosis and cirrhosis of the liver, pericarditis, renal cysts and fibrosis of the testes.
Detection of Hepatitis C Virus Transmission by Use of DNA Mass Spectrometry (2013)

The molecular detection of transmission of rapidly mutating pathogens such as hepatitis C virus (HCV) is commonly achieved by assessing the genetic relatedness of strains among infected patients. We describe the development of a novel mass spectrometry (MS)-based approach to identify HCV transmission. MS was used to detect products of base-specific cleavage of RNA molecules obtained from HCV polymerase chain reaction fragments. The MS-peak profiles were found to reflect variation in the HCV genomic sequence and the intrahost composition of the HCV population. Serum specimens originating from 60 case patients from 14 epidemiologically confirmed outbreaks and 25 unrelated controls were tested. Neighbor-joining trees constructed using MS-peak profile-based Hamming distances showed 100% accuracy, and linkage networks constructed using a threshold established from the Hamming distances between epidemiologically unrelated cases showed 100% sensitivity and 99.93% specificity in transmission detection. This MS-based approach is rapid, robust, reproducible, cost-effective, and applicable to investigating transmissions of other pathogens.
Elastography (2011)

Elastography has emerged as a useful adjunct tool for ultrasound diagnosis. Elastograms are images of tissue stiffness and may be in color, grayscale, or a combination of the two. The first and most common application of elastography is for the diagnosis of breast lesions where studies have shown an area under the receiver operating characteristic curve of 0.88 to 0.95 for distinguishing cancer from benign lesions. The technique is also useful for the diagnosis of complex cysts, although different scanners may vary in how they display such lesions. Recent advances in elastography include quantification using strain ratios, acoustic radiation force impulse imaging, and shear wave velocity estimation. These are useful not only for characterizing focal masses but also for diagnosing diffuse organ diseases such as liver cirrhosis. Other near term potential applications for elastography include characterization of thyroid nodules and lymph node evaluation for metastatic disease. Prostate cancer detection is also a potential application, but obtaining high-quality elastograms may be difficult. This area is evolving. Other promising applications include atheromatous plaque and arterial wall evaluation, venous thrombus evaluation, graft rejection, and monitoring of tumor ablation therapy. When contemplating the acquisition of a system with elastography in this rapidly evolving field, a clear picture of the manufacturer's plans for future upgrades (including quantification) should be obtained.
Azobenzene-Functionalized Cascade Molecules: Photoswitchable Supramolecular Systems (1998)

Potential holographic materials are obtained from the azobenzene-functionalized dendrimers described herein (shown schematically on the right). Even in the largest species presented, which contains up to 32 azobenzene chromophores, each chromophoric unit behaves independently compared to “monomer” model compounds. Diffraction efficiencies larger than 20 % were achieved with holographic films of the azobenzene dendrimers – the second-generation dendrimer exhibits good thermal stability.
Far beyond Phagocytosis: Phagocyte-Derived Extracellular Traps Act Efficiently against Protozoan ParasitesIn VitroandIn Vivo (2016)

Professional mononuclear phagocytes such as polymorphonuclear neutrophils (PMN), monocytes, and macrophages are considered as the first line of defence against invasive pathogens. The formation of extracellular traps (ETs) by activated mononuclear phagocytes is meanwhile well accepted as an effector mechanism of the early host innate immune response acting against microbial infections. Recent investigations showed evidence that ETosis is a widely spread effector mechanism in vertebrates and invertebrates being utilized to entrap and kill bacteria, fungi, viruses, and protozoan parasites. ETs are released in response to intact protozoan parasites or to parasite-specific antigens in a controlled cell death process. Released ETs consist of nuclear DNA as backbone adorned with histones, antimicrobial peptides, and phagocyte-specific granular enzymes thereby producing a sticky extracellular matrix capable of entrapping and killing pathogens. This review summarizes recent data on protozoa-induced ETosis. Special attention will be given to molecular mechanisms of protozoa-induced ETosis and on its consequences for the parasites successful reproduction and life cycle accomplishment.
Diversifying Joint Vision-Language Tokenization Learning (2023)

Building joint representations across images and text is an essential step for tasks such as Visual Question Answering and Video Question Answering. In this work, we find that the representations must not only jointly capture features from both modalities but should also be diverse for better generalization performance. To this end, we propose joint vision-language representation learning by diversifying the tokenization learning process, enabling tokens that are sufficiently disentangled from each other to be learned from both modalities. We observe that our approach outperforms the baseline models in a majority of settings and is competitive with state-of-the-art methods.

The office of the future (1998)

We introduce ideas, proposed technologies, and initial results for an office of the future that is based on a unified application of computer vision and computer graphics in a system that combines and builds upon the notions of the CAVE, tiled display systems, and image-based modeling . The basic idea is to use real-time computer vision techniques to dynamically extract per-pixel depth and reflectance information for the visible surfaces in the office including walls, furniture, objects, and people, and then to either project images on the surfaces, render images of the surfaces , or interpret changes in the surfaces. In the first case, one could designate every-day (potentially irregular) real surfaces in the office to be used as spatially immersive display surfaces, and then project high-resolution graphics and text onto those surfaces. In the second case, one could transmit the dynamic image-based models over a network for display at a remote site. Finally, one could interpret dynamic changes in the surfaces for the purposes of tracking, interaction, or augmented reality applications.
Fertilization and early embryology: Timing of pronuclear development and first cleavages in human embryos after subzonal insemination: influence of sperm phenotype (1995)

The sequential transformations of human sperm nuclei in human eggs after subzonal insemination (SUZI; n = 104) and the influence of sperm defects on this timing were studied. This chronology was compared to that of two control series of zygotes obtained after SUZI with normal spermatozoa (n = 35) and after in-vitro fertilization (IVF) with normal donor spermatozoa (D-IVF; n = 220). Pronuclear formation took place between 4.5 and 10.5 h post-SUZI for 92.8% of the zygotes. They remained visible for 13 h and began to disappear 18.5 h post-SUZI. The timespan 3 h. Zygotes obtained after D-IVF had a similar rate of pronuclear disappearance but approximately 4 h later. The second cell cycle was more rapid for zygotes obtained by D-IVF than by SUZI, but the developmental rate of zygotes obtained by SUZI varied according to sperm phenotypes. For patients with previous unexplained IVF failures (control group with normal spermatozoa), the developmental rate was lower, suggesting the influence of oocyte quality. In conclusion, the end of the first cell cycle of zygotes obtained by insemination under the zona pellucida appears 4 h earlier compared to zygotes obtained after insemination outside the zona pellucida.

2"-Chartreusin-monoacetate, a New Natural Product with Unusual Anisotropy Effects from the Marine Isolate Streptomyces sp. B5525, and its 4"-Isomer (2002)

The marine Streptomycete isolates B5342 and B5525 forms, beside large amounts of the antitumor antibiotic chartreusin (1a), two chartreusin monoacetates as trace components. Whereas the chemical shift of the acetate methyl in 1c is in the normal range, the methyl group of the 2"-acetate residue in 1b and also in the tetra- and pentaacetates shows an extreme upfield shift. The structures of the monoacetates were confirmed by extensive NMR experiments, the anisotropic shift is explained by semi-empirical calculations.
Sequential sampling algorithm for simultaneous near-field scanning of amplitude and phase (2014)

This paper describes an automated sequential sampling algorithm for EMI near-field scanning of electronic systems which allows to measure both magnitude and phase of the electromagnetic near-fields simultaneously. The main goal of the sequential sampling algorithm is to drastically reduce the total measurement time to obtain a complete model of the electronic system's near-field distribution. Measuring both magnitude and phase is important for predicting the far-field emission from the near-field or for building equivalent radiation models of the device under test. Previous work described such a sequential sampling algorithm for amplitude-only measurements. The extension towards both amplitude and phase poses two challenges. First, the underlying sampling and modelling techniques have to be adapted such that they can handle building up two separate models at the same time using a common set of optimal sampling points and without significant increase of the measurement time. Second, a good choice has to be made with respect to which components will be sampled and modelled. It is shown that the most advantageous choice is to sample and model the real and imaginary components of the near-fields instead of the amplitude and phase directly.
Performance of visual search tasks from various types of contour information (2013)

A recently proposed visual aid for patients with a restricted visual field (tunnel vision) combines a see-through head-mounted display and a simultaneous minified contour view of the wide-field image of the environment. Such a widening of the effective visual field is helpful for tasks, such as visual search, mobility, and orientation. The sufficiency of image contours for performing everyday visual tasks is of major importance for this application, as well as for other applications, and for basic understanding of human vision. This research aims is to examine and compare the use of different types of automatically created contours, and contour representations, for practical everyday visual operations using commonly observed images. The visual operations include visual searching for items, such as cutlery, housewares, etc. Considering different recognition levels, identification of an object is distinguished from mere detection (when the object is not necessarily identified). Some nonconventional visual-based contour representations were developed for this purpose. Experiments were performed with normal-vision subjects by superposing contours of the wide field of the scene over a narrow field (see-through) background. From the results, it appears that about 85% success is obtained for searched object identification when the best contour versions are employed. Pilot experiments with video simulations are reported at the end of the paper.
Experimental Access to the Instantaneous Spectrum of MEMS-Based Swept Source (2018)

Genome-wide hydroxymethylation profiles in liver of female Nile tilapia with distinct growth performance (2023)

The mechanisms underlying the fast genome evolution that occurs during animal domestication are poorly understood. Here, we present a genome-wide epigenetic dataset that quantifies DNA hydroxymethylation at single nucleotide resolution among full-sib Nile tilapia (Oreochromis niloticus) with distinct growth performance. In total, we obtained 355 million, 75 bp reads from 5 large- and 5 small-sized fish on an Illumina NextSeq500 platform. We identified several growth-related genes to be differentially hydroxymethylated, especially within gene bodies and promoters. Previously, we proposed that DNA hydroxymethylation greatly affects the earliest responses to adaptation and potentially drives genome evolution through its targeted enrichment and elevated nucleotide transversion rates. This dataset can be analysed in various contexts (e.g., epigenetics, evolution and growth) and compared to other epigenomic datasets in the future, namely DNA methylation and histone modifications. With forthcoming advancements in genome research, this hydroxymethylation dataset will also contribute to better understand the epigenetic regulation of key genomic features, such as cis-regulatory and transposable elements.
Low-Temperature Postfunctionalization of Highly Conductive Oxide Thin-Films toward Solution-Based Large-Scale Electronics (2017)

Although transparent conducting oxides (TCOs) have played a key role in a wide range of solid-state electronics from conventional optoelectronics to emerging electronic systems, the processing temperature and conductivity of solution-processed materials seem to be far exceeding the thermal limitations of soft materials and insufficient for high-perfomance large-area systems, respectively. Here, we report a strategy to form highly conductive and scalable solution-processed oxide materials and their successful translation into large-area electronic applications, which is enabled by photoassisted postfunctionalization at low temperature. The low-temperature fabrication of indium-tin-oxide (ITO) thin films was achieved by using photoignited combustion synthesis combined with photoassisted reduction process under hydrogen atmosphere. It was noteworthy that the photochemically activated hydrogens on ITO surface could be triggered to facilitate highly crystalline oxygen deficient structure allowing significant increase of carrier concentration and mobility through film microstructure modifications. The low-temperature postfunctionalized ITO films demonstrated conductivity of >1607 S/cm and sheet resistance of <104 Ω/□ under the process temperature of less than 300 °C, which are comparable to those of vacuum-deposited and high-temperature annealed ITO films. Based on the photoassisted postfunctionalization route, all-solution-processed transparent metal-oxide thin-film-transistors and large-area integrated circuits with the ITO bus lines were demonstrated, showing field-effect mobilities of >6.5 cm<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup> with relatively good operational stability and oscillation frequency of more than 1 MHz in 7-stage ring oscillators, respectively.
Low resistance thin film organic solar cell electrodes (2023)

A method which lower the series resistance of photosensitive devices includes providing a transparent film of a first electrically conductive material arranged on a transparent substrate; depositing and patterning a mask over the first electrically conductive material, such that openings in the mask have sloping sides which narrow approaching the substrate; depositing a second electrically conductive material directly onto the first electrically conductive material exposed in the openings of the mask, at least partially filling the openings; stripping the mask, leaving behind reentrant structures of the second electrically conductive material which were formed by the deposits in the openings of the mask; after stripping the mask, depositing a first organic material onto the first electrically conductive material in between the reentrant structures; and directionally depositing a third electrically conductive material over the first organic material deposited in between the reentrant structures, edges of the reentrant structures aligning deposition so that the third electrically conductive material does not directly contact the first electrically conductive material, and does not directly contact the second electrically conductive material.
