Iron nanoparticles: Synthesis and applications in surface enhanced Raman scattering and electrocatalysis (2001)

The microemulsion method is employed to synthesize iron nanoparticles with an average size of ∽3 nm using trioctyl phosphine oxide (TOPO) as a stabilizing agent. The morphology, structure, and composition of the nanoparticles are studied by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV–VIS spectroscopy. The iron nanoparticles show a remarkable surface-enhanced Raman scattering (SERS) activity, and the scheme of iron nanoparticle-on-electrode is successfully used in the in situ SERS study of adsorbed molecules. Electrocatalysis over the iron nanoparticles is demonstrated in the highly efficient and selective reduction of H2O2 in the presence of oxygen.
Study of some distance measures for language and encoding identification (2006)

To determine how close two language models (e.g., n-grams models) are, we can use several distance measures. If we can represent the models as distributions, then the similarity is basically the similarity of distributions. And a number of measures are based on information theoretic approach. In this paper we present some experiments on using such similarity measures for an old Natural Language Processing (NLP) problem. One of the measures considered is perhaps a novel one, which we have called mutual cross entropy. Other measures are either well known or based on well known measures, but the results obtained with them vis-avis one-another might help in gaining an insight into how similarity measures work in practice.
Design fixation: Classifications and modern methods of prevention (2014)

Abstract The term design fixation is often used interchangeably to refer to situations where designers limit their creative output because of an overreliance on features of preexisting designs, or more generally, an overreliance on a specific body of knowledge directly associated with a problem. In this paper, we argue that interdisciplinary interest in design fixation has led to increasingly broad definitions of the phenomenon that may be undermining empirical research efforts, educational efforts to minimize fixation, and the acquisition and dissemination of transdisciplinary knowledge about fixation effects. To address these issues, we recommend that researchers consider categorizing fixation phenomena into one of three classifications: unconscious adherence to the influence of prior designs, conscious blocks to change, and intentional resistance to new ideas. Next, we distinguish between concept-based design fixation, fixation to a specific class of known design concepts, and knowledge-based design fixation, fixation to a problem-specific knowledge base. With these distinctions in place, we propose a system of orders of design fixation, recommend methods for reducing fixation in inventive design, and recommend areas that are in need of further research within the field of design science.
The application of modern methods for bridge diagnostics and load testing (2023)

Abstract The paper deals with the modern methods of testing and diagnostics of existing, mainly steel, bridges. The focus is on the DIC method (digital image correlation) and its application for the static measurements and dynamic measurements of the bridge deflection at high speeds and on the detection of the behavior of bridge details, such as pins and fatigue cracks. The sources of potential related error values are identified and possible strategies for the minimization of errors corresponding to the DIC field measurements are developed and described in the paper. The proposed DIC methods were successfully applied on the deflection measurement on long distances and on the measurement of the strain on details in‐situ. Relevant applications were done in the Czech Republic as a part of the bridge load testing and the results are discussed in the paper.
Poszt-COVID–19-szindrómás esetek kialakulásának követése (2022)

Introduction: Extended symptoms may develop after a SARS-CoV-2 infection. We refer to these as post-COVID–19 symptoms and they are grouped according to time duration. Objective: The aim of the study was to follow all COVID–19 infected patients in a family practise, to observe all post-COVID–19 symptoms, symptom development rates and to document how long they last. Method: 282 SARS-CoV-2 patients were followed mainly through telephone interviews between 01. 09. 2020 and 01. 09. 2021. Post-COVID–19 symptoms were monitored for 15–42 weeks every 4 weeks (30–50 weeks in cases of delayed hypsomia). Results: Symptoms lasting longer than a month developed in 67% of all patients (170 cases). The most frequent symptoms were fatigue (79 cases, 29%) and hyposmia (74 cases, 27%). The latter mainly developed in non-smokers, affecting 2,5% of all COVID–19 patients beyond 43 weeks. Fatigue affected 46% of all post-COVID–19 patients. Sick leave was significantly longer among these patients (19.7 vs. 12.3 days in patients with no fatigue). Severe post-COVID–19 fatigue in non-hospitalized patients presented in a sydrome-like appearance displaying palpitations, fatigue, dyspnoea, sleep disturbances, loose stools and postural complaints. These regrediated after 19 weeks. Discussion: Post-COVID–19 symptoms often develop after a mild COVID–19 infection. Severity of COVID–19 infection and severity of post-COVID–19 symptoms often do not correlate. Groups of hospitalized and non-hospitalized post-acute COVID patients with fatigue can be distinguished by many attributes. Conclusion: Mild COVID–19 infections may also be followed up by severe fatigue, but it spontenaously regrediates. Long-term effects of COVID–19 are permanent hyposmia and fatigue (the latter affect some hospitalized COVID–19 patients). Orv Hetil. 2022; 163(9): 335–342.
Markets for Cybercrime Tools and Stolen Data: Hackers' Bazaar (2014)

Criminal activities in cyberspace are increasingly facilitated by burgeoning black markets. This report characterizes these markets and how they have grown into their current state to provide insight into how their existence can harm the information security environment. Understanding these markets lays the groundwork for exploring options to minimize their potentially harmful influence.
SARS-CoV-2 infection induces a pro-inflammatory cytokine response through cGAS-STING and NF-κB (2022)

SARS-CoV-2 is a novel virus that has rapidly spread, causing a global pandemic. In the majority of infected patients, SARS-CoV-2 leads to mild disease; however, in a significant proportion of infections, individuals develop severe symptoms that can lead to long-lasting lung damage or death. These severe cases are often associated with high levels of pro-inflammatory cytokines and low antiviral responses, which can cause systemic complications. Here, we have evaluated transcriptional and cytokine secretion profiles and detected a distinct upregulation of inflammatory cytokines in infected cell cultures and samples taken from infected patients. Building on these observations, we found a specific activation of NF-κB and a block of IRF3 nuclear translocation in SARS-CoV-2 infected cells. This NF-κB response was mediated by cGAS-STING activation and could be attenuated through several STING-targeting drugs. Our results show that SARS-CoV-2 directs a cGAS-STING mediated, NF-κB-driven inflammatory immune response in human epithelial cells that likely contributes to inflammatory responses seen in patients and could be therapeutically targeted to suppress severe disease symptoms.
SDN-Assisted adaptive streaming framework for tile-based immersive content using MPEG-DASH (2017)

Video streaming over the internet for new 3D immersive media such as Virtual Reality and 360-degree videos has drawn great attention from both consumers and researchers in recent years. One of the biggest challenges in streaming such 3D media is the high bandwidth demands. While traditional 2D video streaming is still dominating network peak traffic, new inventions are accelerating the adoption of immersive contents and devices. A new Tile-based video is introduced in both a video codec and streaming layer to reduce the transferred media size. Dynamic adaptive streaming over HTTP has become one of the de facto effective adaptive streaming approaches that can fully utilize the existing physical IP network infrastructure. In this paper, we propose a tile-based streaming framework using software-defined networking. By prioritizing streaming flows, based on the region of interests, our approach can improve the user's quality of experience (QoE).
Preparation and Characterization of Double Metal Cyanide Complex Catalysts (2003)

A series of double metal cyanide (DMC) complex catalysts were prepared in two different methods by using ß-cyclodextrin, PEG-1000 and Tween-60 as an additional complex ligands respectively. It was showed that a mixture of crystalline and amorphous DMC was synthesized by using traditional method in which the additional complex ligand was added after the precipitation of DMC. Amorphous and dispersed DMC with higher activity could be obtained when the additional complex ligand was added in the reactant solution before reaction. The effect of additional complex ligand and preparation method on the crystalline state and catalytic property of DMC were also investigated.
Instance-Level Salient Object Segmentation (2017)

Image saliency detection has recently witnessed rapid progress due to deep convolutional neural networks. However, none of the existing methods is able to identify object instances in the detected salient regions. In this paper, we present a salient instance segmentation method that produces a saliency mask with distinct object instance labels for an input image. Our method consists of three steps, estimating saliency map, detecting salient object contours and identifying salient object instances. For the first two steps, we propose a multiscale saliency refinement network, which generates high-quality salient region masks and salient object contours. Once integrated with multiscale combinatorial grouping and a MAP-based subset optimization framework, our method can generate very promising salient object instance segmentation results. To promote further research and evaluation of salient instance segmentation, we also construct a new database of 1000 images and their pixelwise salient instance annotations. Experimental results demonstrate that our proposed method is capable of achieving state-of-the-art performance on all public benchmarks for salient region detection as well as on our new dataset for salient instance segmentation.
Advances in Biotechnology: New Tools in Future Pig Production for Agriculture and Biomedicine (2003)

Biotechnology in livestock comprises an arsenal of reproductive biotechniques and molecular genetics. While molecular genetics are poorly developed in swine, reproductive techniques are more advanced and applied under field conditions. This review describes three selected examples of our own research to illustrate the implication of biotechnology in future pig reproduction. Sperm sexing technology is now available and can be used to generate piglets of the desired sex by IVF and ICSI. First studies also indicate satisfactory success rates following intrauterine insemination with sexed spermatozoa. Cloning technique and production of transgenic pigs require information about the regulation and time course of gene expression during in vitro production and pre-implantation development. Information on gene expression is scare in porcine embryos. With the exception of transcripts for the oestrogen receptor gene, no mRNA's from the activated porcine genome have been identified. Recent development of cDNA arrays might help to identify a larger amount of genes in single embryos. Remarkable progress has been made in organ transplantation technology. As the demand for human organs is increasing rapidly, the pig might serve as donor of xenotranplants, provided the transmission of zoonoses from the donor animal to the human recipient is prevented, donor organ anatomy and function are compatible, and immunological rejections (HAR, VAR MAC) can be overcome. The most promising strategy is the synthesis of human complement regulatory proteins in the pig. Transgenic pigs have been generated for hDAF or hCD 46 and their hearts have been transplanted into non human primates for up to 90 days. HCD 59 driven by CMV promotor provides significant protection against HAR at least under in vitro and in vivo conditions. Current studies indicate a temporary use in patients within the next 3-5 years. As the microinjection technology to produce transgenic offspring is time consuming and very expensive, nuclear transfer technology provides a possibility for multiplication without going through the germ line with recombination effects. A functional nuclear transfer system will be crucial for xenotransplantation as it is anticipated that the expression of several transgenes will be required.

Isolation and Hypoglycemic Activity of Ephedrans A, B, C, D and E, Glycans of<i>Ephedra distachya</i>Herbs<sup>1</sup> (1985)

Administration of an aqueous methanol/water extract of the Oriental crude drug "maō" (Ephedra), Ephedra distachya herbs, caused transient hyperglycemia followed by long lasting hypoglycemia in mice. Activity-guided fractionation of the extract led to isolation of five glycans, ephedrans A, B, C, D and E, which exhibited significant hypoglycemic effects in normal and alloxan-induced hyperglycemic mice.
Solvent-Mediated Self-Assembly of Nanocube Superlattices (2014)

Self-organization of colloidal Pt nanocubes into two types of distinct ordered superlattices, simple-cubic and body-centered-tetragonal structures, has been achieved using a home-built setup. Detailed translational and orientational characteristics of these superstructures were determined using a transmission electron microscopy tomographic technique with 3D reconstruction analysis. The formation of these distinct superlattices is the result of a delicate choice of solvent (i.e., aliphatic hexane or aromatic toluene hydrocarbons), which serves as a dispersion medium to fine-tune the relative strengths of ligand-ligand and ligand-solvent interactions during the self-assembly process. This work provides important insights into the effects of ligand-solvent interactions on superlattice formation from nonspherical nanoparticles.
Nonlinear acoustic echo cancellation using a Hammerstein model (2002)

In hands-free telephone or video conference application, there exists an acoustic feedback coupling between the loudspeaker and microphone, which creates the acoustic echo. Linear acoustic echo cancellers (AECs) are commonly used to remove this echo. However, they are unable to effectively cancel nonlinear distortions. This paper employs a Hammerstein model to describe the acoustic channel of a nonlinear system concatenated with a linear faded echo path. A feed-forward neural network is used to model the static nonlinearity and a finite impulse response (FIR) structure is used to model the linear dynamic system. The formed nonlinear model is applied to real data collected in an anechoic chamber and it performs slightly better than linear models. Although the improvement is small, the results show some interesting insights on the characteristic of a loudspeaker's nonlinearities and their effect on the performance of an AEC.
Processing of wearable sensor data on the cloud - a step towards scaling of continuous monitoring of health and well-being (2010)

As part of a sleep monitoring project, we used actigraphy based on body-worn accelerometer sensors to remotely monitor and study the sleep-wake cycle of elderly staying at nursing homes. We have conducted a fifteen patient trial of a sleep activity pattern monitoring (SAPM) system at a local nursing home. The data was collected and stored in our server and the processing of the data was done offline after sleep diaries used for validation and ground truth were updated into the system. The processing algorithm matches and annotates the sensor data with manual sleep diary information and is processed asynchronously on the grid/cloud back end. In this paper we outline the mapping of the system for grid / cloud processing, and initial results that show expected near-linear performance for scaling the number of users.
Amniotic fluid acetylcholinesterase measurement in the prenatal diagnosis of open neural tube defects. Second report of the collaborative acetylcholinesterase study (1989)

Seventeen centres from Australia, Britain, France, and the United States collaborated in a study to compare amniotic fluid acetylcholinesterase (AChE) determination by gel electrophoresis and amniotic fluid alpha-fetoprotein (AFP) measurement as diagnostic tests for open neural tube defects. The study was based on 32,642 women with singleton pregnancies (including 428 with open spina bifida and 238 with anencephaly) who had an amniocentesis at 13-24 weeks' gestation. The AChE test yielded a detection rate for open spina bifida of 99 per cent (95 per cent confidence interval 98-100 per cent), 98 per cent for anencephaly (95 per cent confidence interval 96-100 per cent), and a false-positive rate of 0.34 per cent (95 per cent confidence interval 0.28-0.40 per cent) excluding miscarriages, intrauterine death, and serious fetal abnormalities. The false-positive rate was 0.30 per cent among the 13 centres that used a specific AChE inhibitor in the test. Comparable rates for the AFP test were less favourable. (For example, the open spina bifida detection rate was 90 per cent and the false-positive rate was 0.46 per cent using the cut-off levels specified in the U.K. Collaborative AFP Study.) The AChE false-positive rate was lower in samples that were not bloodstained (0.16 per cent) than in those that were (2.4 per cent). It was higher in women who had an amniocentesis on account of a raised maternal serum AFP level (0.56 per cent) than in those who had one for other reasons (0.29 per cent). The best results were obtained by a combination of the two tests, an effective and economical policy being to perform the AFP measurement on all amniotic fluid samples and an AChE test on samples with AFP levels greater than or equal to 2.0 multiples of the normal median (about 5 per cent of all samples). Using this policy, the open spina bifida detection rate was 96 per cent and the false-positive rate was 0.14 per cent (0.06 per cent for samples that were not bloodstained and 1.2 per cent for those that were; 0.40 per cent for women with raised serum AFP levels and 0.09 per cent for other women). This policy offers a useful improvement to the prenatal diagnosis of open spina bifida.
QChIPat: a quantitative method to identify distinct binding patterns for two biological ChIP-seq samples in different experimental conditions (2013)

Several advantages of our program include: 1) it considers a control (or input) experiment; 2) it incorporates a novel global normalization strategy: nonparametric empirical Bayes correction normalization; 3) it provides the binding pattern information among different enriched regions. QChIPat is implemented in R, Perl and C++, and has been tested under Linux. The R package is available at http://motif.bmi.ohio-state.edu/QChIPat.
Omega-3 fatty acids (2013)

Overall, these results emphasize that blood concentrations of individual long-chain polyunsaturated fatty acids, which reflect both dietary intake and metabolic influences, may have independent, but also complementary- biological effects and reinforce the need to potentially provide a complex mixture of omega-3 fatty acids to maximize cardiovascular risk reduction.
Brooklyn Gentrification and the Act of Settling in Lionel Shriver’s The Mandibles (2021)

Contemporary Brooklyn fictions, as a genre, are centrally concerned with gentrification and authenticity. This article situates literary Brooklyn and these concerns in relation to the United States at the national level. Thinking about Brooklyn’s gentrification demands one to be necessarily cognizant of the borough as a social, cultural, economic, and psychological space within the context of the US as a colonial nation-state. I argue that Lionel Shriver’s The Mandibles (2016), whose titular characters are enactors of both Brooklyn gentrification and a romanticized act of settlement in a fictional new nation-state, exemplifies this link between gentrification at the local level and a search for authenticity at the national level. Through a reading of the novel, I argue that Brooklyn gentrification is intimately bound with US settler colonialism, which in The Mandibles is sustained by the novel’s representations of finance and the whiteness of its narrative focalization.
Performance of Using Antenna Arrays to Generate and Receive mm-Wave Orbital-Angular-Momentum Beams (2017)

Generation and detection of millimeter-wave carrying orbital angular momentum (OAM) have been of growing interest. In this paper, we evaluate patch antenna arrays with different arrangements as OAM generators and receivers by simulation. We compare beam evolution processes and steering performance for circular and ring-antenna-array based OAM links. Mode purity of the generated OAM +1 beam fluctuates between 10% and 99% for ring antenna arrays with 10 cm diameters while it remains >99% for circular antenna arrays. Compared to a ring-antenna-array based link, the circular-antenna-array based link could have an ~10 dB lower power loss at the distance up to 0.5m. We also show that a 5cm diameter circular antenna array could steer an OAM +1 beam up to 80° with a mode purity degradation of <;1%, while ring antenna arrays have ~10% mode purity degradation. OAM spectrum analysis shows both the lattice shape and the boundary shape of an antenna array could cause power leakage to harmonic OAM orders. Such power leakages would increase as the designed OAM order or the lattice period d increases, while it would decrease as the array diameter D increases.
