<b>MACROPHAGE-LIKE CHEMOTACTIC HYBRIDOMAS ACTIVE FOR VARIOUS CHEMOTACTIC </b><b>FACTORS </b> (1984)

Mouse inflammatory macrophages taken from casein-induced pleural exudates (the CANS series) and mineral oil-induced peritoneal exudates (the ONS series) of C57BL/6N (B6) mice (H-2*') were fused with BALB/c mouse (H-2") derived myeloma cells. After selection of somatic cell hybrids, cloning and prolonged culture, two clones (CANS-196 and ONS-2C lines) strongly chemotactic to bacterial chemotactic factor and C5a were obtained. These lines also showed rosette forming abilities with sheep red blood cells (SRBC) coated with rabbit IgG anti-Forssman antibody (EA) and IgM followed by complement (EAC) and phagocytic activity, and produced lysozyme. By recloning of these clones, chemotactic subclones active for N-formylmethionyl-leucyl-phenylalanine benzyl ester (FMLP), zymosan-activated serum from AKR mice (ZAS(AKR)) and lymphocyte-derived chemotactic factor in addition to bacterial chemotactic factor and C5a, were successfully separated. Parental casein-or mineral oil-induced exudate macrophages responded to all these agents weakly, but significantly. CANS-196 and ONS-2C lines in the early period after cell fusion (8 weeks) displayed no chemotactic activity. They had high chromosome numbers (78 and 76 chromosomes, respectively) and both H-2'" and H-2" antigens on their surface, confirming that these lines were hybridized cells. However, when these lines became chemotactic (28 and 20 weeks after cell fusion, respectively) they had low chromosome numbers (42-43 chromosomes) and lost the H-2" antigen, although expression of the H-2" antigen remained unchanged. At the same time, these lines newly expressed certain aged hybridoma specific cell surface antigens which were detectable by BALB/c anti-aged CANS-196 and ONS-2C cell alloantisera. Reasons for the necessity of prolonged culture for the establishment of stable macrophage-like chemotactic hybridomas, and changes in the expression of cell surface antigens are discussed in the context of chromosome loss. A Macrophage-like cell lines have been utilized for the investigation of macrophage functions, e.g., Abbreviations." B6, C57BL/6N; SRBC, sheep red blood cells; EA, SRBC coated with rabbit IgG anti-Forssman antibody; EAC, SRBC coated with rabbit IgM anti-Forssman antibody followed by complement; FMLP, N-formyl-methionyl-leucyl-phenylalanine benzyl ester; ZAS(AI(R), zymosan activated serum from AKR mice; NSI, P3/NSI-Ag-1; DMEM, Du]becco's modified Eagle's medium; DMSO, dimethyl sulfoxide; FCS, fetal calf serum; HAT medium, DMEM containing hypoxanthine, aminopterin and thymidine adherence, rosette formation, phagocytosis, antibody dependent cell mediated cytotoxicity, immunoregulation, secretion of enzymes or biologically active materials ( 22, 27). The use of these cell lines has enabled investigators quantitatively and qualitatively to handle phagocytic cells much easier than primary macrophages, which are heterogeneous both in populations and in differentiation stages.
CapGlasses: Untethered Capacitive Sensing with Smart Glasses (2021)

Augmenting the human body using wearable technology can be particularly interesting to sense context. The user’s context includes the mental and physical state, which is inferable by detecting facial and head related gestures. For the recognition of these gestures, we propose instrumenting a pair of glasses with Capacitive Sensing (CapSense) technology. We demonstrate proximity sensing with CapSense for mobile use despite its commonly known limitations in context of mobility. Moreover, we demonstrate how to incorporate transparent sensing electrodes into the glass and copper electrodes into the frame while being potentially invisible in a future specs product. We demonstrate an untethered battery-powered glasses prototype, CapGlasses, to sense facial expressions and head gestures. We selected a set of 12 gestures and ran a study with 12 users. We obtained an average accuracy of 89.6% by a user-dependent machine learning model. We focused on providing clear documentation to enable a straightforward replication of our technology.
Epileptogenesis Induced by Alternate‐site Kindling in Bilateral Hippocampi (2003)

The present AK procedure did not induce kindling antagonism, but it induced progression of kindling manifestations. The origin of simple B-type IID is known to be in the contralateral side, and its intracellular counterpart corresponds to a sequence of small depolarization followed by large hyperpolarization, suggesting that plastic changes in the feed-forward inhibitory system play an important role in hippocampal kindling.
Data Augmentation using Pre-trained Transformer Models (2020)

Language model based pre-trained models such as BERT have provided significant gains across different NLP tasks.In this paper, we study different types of transformer based pretrained models such as auto-regressive models (GPT-2), auto-encoder models (BERT), and seq2seq models (BART) for conditional data augmentation.We show that prepending the class labels to text sequences provides a simple yet effective way to condition the pre-trained models for data augmentation.Additionally, on three classification benchmarks, pre-trained Seq2Seq model outperforms other data augmentation methods in a low-resource setting.Further, we explore how different data augmentation methods using pre-trained model differ in-terms of data diversity, and how well such methods preserve the class-label information.
Recurrent Neural Networks for Automatic Replay Spoofing Attack Detection (2018)

In order to enhance the security of automatic speaker verification (ASV) systems, automatic spoofing attack detection, which discriminates the fake audio recordings from genuine human speech, has gain much attention recently. Among various ways of spoofing attacks, replay attacks are one of the most effective and economical methods. In this paper, we explore using recurrent neural networks for automatic replay spoofing attack detection. More specifically, we focus on recurrent neural networks with more sophisticated recurrent units that involve a gating mechanism, such as a long short term memory (LSTM) unit and a recently proposed gated recurrent unit (GRU). Our experimental results on the ASVspoof 2017 showed that neural networks significantly outperform Gaussian mixture models (GMM). In addition, we achieved the best equal error rate of 9.81 % on the ASVspoof2017 and 1.077% on the BTAS 2016 by using GRU models, which outperform the best feed-forward neural networks by 19% and 46%, relatively and respectively.
The Advantages of In Situ Surfactant Generation for Miniemulsions (2010)

The stabilisation of miniemulsions using an in situ generated surfactant is presented. This surfactant, prepared from of a water-soluble base and an oil-soluble long chain acid was successfully used to create stable miniemulsions with up to 60 vol.-% organic phase. It is shown that the creation of a surface active species at the oil-water interface allowed stable miniemulsions to be generated more rapidly than when using conventional surfactant. In addition, polymerised miniemulsions exhibited less secondary nucleation when in situ surfactants were used.
Possible Role of Exosomes Containing RNA in Mediating Nontargeted Effect of Ionizing Radiation (2012)

Communication between irradiated and un-irradiated (bystander) cells can cause damage in cells that are not directly targeted by ionizing radiation, a process known as the bystander effect. Bystander effects can also lead to chromosomal/genomic instability within the progeny of bystander cells, similar to the progeny of directly irradiated cells. The factors that mediate this cellular communication can be transferred between cells via gap junctions or released into the extracellular media following irradiation, but their nature has not been fully characterized. In this study we tested the hypothesis that the bystander effect mediator contains an RNA molecule that may be carried by exosomes. MCF7 cells were irradiated with 2 Gy of X rays and the extracellular media was harvested. RNase treatment abrogated the ability of the media to induce early and late chromosomal damage in bystander cells. Furthermore, treatment of bystander cells with exosomes isolated from this media increased the levels of genomic damage. These results suggest that the bystander effect, and genomic instability, are at least in part mediated by exosomes and implicate a role for RNA.
Intelligent self-tuning controllers for robot manipulators (2002)

The design problem of an intelligent self-tuning controller, characterized by a two-layer hierarchical structure, is addressed. The layers are organized according to their functions and goals. The control level is implemented as a self-tuning adaptive controller, where a variety of control laws and identification methods exist as candidates for the controller and identification portions, respectively. Integration of a controller-estimator pair is carried out according to the guidelines provided by the coordination level. The organization level, implemented as a Petri network, supervises the control level, serves as an interface between the user and the system, and resolves several issues which arise from the coordination process between the two layers
Reduction of simultaneous switching noise in analog signal band (2007)

In this work we focus on reducing the simultaneous switching noise located in the frequency band from DC up to half of the digital clock frequency. This frequency band is assumed to be the signal band of an analog circuit. The idea is to use circuits that have as periodic power supply currents as possible to obtain low simultaneous switching noise below the clock in the frequency domain. We use precharged differential cascode switch logic together with a novel D flip-flop. To evaluate the method two pipelined adders have been implemented on transistor level in a 0.13 mum CMOS technology, where the novel circuit is implemented with our method and the reference circuit with static CMOS logic together with a TSPC D flip-flop. According to simulation results, the frequency components in the analog signal band can be attenuated from 10 dB up to 17 dB when using the proposed method. The cost is an increase in power consumption of almost a factor of three and a higher transistor count.
Dependency of the photonic band gaps in two-dimensional metallic photonic crystals on the shapes and orientations of rods (2012)

Photonic bands in two types of two-dimensional metallic photonic crystals (2-D MPCs), which are composed of dielectric rods embedded into a metallic background (type I MPCs) and metallic rods in a dielectric background (type II MPCs), are investigated theoretically using a method based on the frequency-dependent plane-wave expansion method. We discuss the maximization of the normalized gap width as a function of the rod shapes and orientations. In addition, we study the effect of dielectric constants of the rods and the background on the width of the photonic band gap. Four different shapes of rods-square, circular, diamond, and rectangular-are considered. The numerical results show that the type I MPCs have a higher normalized gap width than the type II MPCs. We observe that the rotation of the noncircular rods in the type I MPCs leads to a slight variation, less than 10%, in the normalized values of the gap width in the two lattice structures. However, rotating the metallic square rods arranged in a square lattice results in doubling of the normalized gap width. The normalized gap width can be tailored by changing the dielectric constant of the rods (background) in type I (type II) MPCs.
Exploration of Practical HEVC/H.265 Sample Adaptive Offset Encoding Policies (2014)

A new in-loop filter, sample adaptive offset (SAO) allows the latest video compression standard, HEVC or H.265, to achieve higher coding efficiency both in objective and subjective measures. However, it requires additional operations to estimate the best SAO parameters per coding tree unit (CTU) during the video encoding process, which often leads to many practical issues such as high computational complexity or architectural inefficiency that might not be affordable for low power or real-time video encoders. In this paper, we explore various SAO encoding policies including complexity reduction in the SAO parameter estimation and efforts to remove inefficiency caused by its implementation in a pipelined manner through numerous experimental tests.
X-ray Powder Diffraction Data and Structure Refinement of TeO <sub>3</sub> (1988)

Abstract The structure of TeO 3 , first published by Dumora and Hagenmuller (1968), was redetermined from new X-ray data collected with a powder diffractometer using space group R3̄c with a = 4.901(2), c = 13.030(4) Å, V = 271.05(8) Å 3 and Z = 6. Intensity data were obtained with CuKα, radiation (λ = 1.540598 Å). Structure refinement was performed with 49 reflections and led to R = 0.058. The material is isostructural with FeF 3 . Powder data are given.
Combination of N,N',N"-triethylenethiophosphoramide and cyclophosphamide in vitro and in vivo. (1988)

In vitro and in vivo studies with the drug combination thioTEPA and cyclophosphamide (CPA) were carried out using the MCF-7 human breast carcinoma cell line and the EMT6 mouse mammary carcinoma cell line. In vitro, survival curves were essentially linear. The EMT6 cell line was less sensitive to thioTEPA than the MCF-7 cell line, with concentrations which reduce cell survival to 10% of 440 and 140 microM, respectively. The response of both cell lines to 4-hydroperoxycyclophosphamide was similar. Simultaneous and immediate sequential treatments with these drugs produced supraadditive cell killing of both cell lines, although the magnitude of the supraadditivity was greater in the MCF-7 cell line than in the EMT6 cell line. Both of these drugs appeared to be as effective as thiol-depleting agents as is diethyl maleate. By DNA alkaline elution, there was a pattern of increasing DNA cross-linking similar to the increasing levels of cytotoxicity of this drug combination with increasing thioTEPA concentrations. In the EMT6 tumor in vivo, the maximally tolerated combination therapy (5 mg/kg x 6 thioTEPA and 100 mg/kg x 3 CPA) produced about 25 days of tumor growth delay which was not significantly different than expected for additivity of the individual drugs. The survival of EMT6 tumor cells after treatment of the animals with various single doses of thioTEPA and CPA was assayed. Tumor cell killing by thioTEPA produced a very steep, linear survival curve through 5 logs. The tumor cell survival curve for CPA out to 500 mg/kg gave linear tumor cell kill through almost 4 logs. In all cases, the combination treatment tumor cell survivals fell well within the envelope of additivity. Both of these drugs are somewhat less toxic toward bone marrow cells by the granulocyte-macrophage colony-forming unit in vitro assay method than to tumor cells. The combination treatments were subadditive or additive in bone marrow granulocyte-macrophage colony-forming unit killing. When bone marrow is the dose-limiting tissue, there is a therapeutic advantage to the use of this drug combination.
Influence of CrgA on Assembly of the Cell Division Protein FtsZ during Development of <i>Streptomyces coelicolor</i> (2006)

The product of the crgA gene of Streptomyces coelicolor represents a novel family of small proteins. A single orthologous gene is located close to the origin of replication of all fully sequenced actinomycete genomes and borders a conserved gene cluster implicated in cell growth and division. In S. coelicolor, CrgA is important for coordinating growth and cell division in sporogenic hyphae. In this study, we demonstrate that CrgA is an integral membrane protein whose peak expression is coordinated with the onset of development of aerial hyphae. The protein localizes to discrete foci away from growing hyphal tips. Upon overexpression, CrgA localizes to apical syncytial cells of aerial hyphae and inhibits the formation of productive cytokinetic rings of the bacterial tubulin homolog FtsZ, leading to proteolytic turnover of this major cell division determinant. In the absence of known prokaryotic cell division inhibitors in actinomycetes, CrgA may have an important conserved function influencing Z-ring formation in these bacteria.
SHEEP, GOATS, LAMBS and WOLVES: a statistical analysis of speaker performance in the NIST 1998 speaker recognition evaluation (1998)

Abstract : Performance variability in speech and speaker recognition systems can be attributed to many factors. One major factor, which is often acknowledged but seldom analyzed, is inherent differences in the recognizability of different speakers. In speaker recognition systems such differences are characterized by the use of animal names for different types of speakers, including sheep, goats, lambs and wolves, depending on their behavior with respect to automatic recognition systems. In this paper we propose statistical tests for the existence of these animals and apply these tests to hunt for such animals using results from the 1998 NIST speaker recognition evaluation.
Accuracy and Distortion of Deep Brain Stimulation Electrodes on Postoperative MRI and CT (2008)

The size of the electrodes' artefact was smaller on CT compared to MR. Furthermore, the position was not precisely concentric around the electrode. Nevertheless, the mean deviation after measuring the contact position in both CT and MR was less than 1 mm in all three planes. Both techniques are eligible for postoperative localisation of DBS electrodes, with a small imprecision of the non-stereotactic MR compared to the stereotactic CT. This might be compensated by the fact that postoperative MR can rule out asymptomatic postoperative complications e.g. haemorrhages or infarctions, without radiation exposure of the patient.
Extraction of Perchlorate Using Porous Organosilicate Materials (2013)

Sorbent materials were developed utilizing two morphological structures, comprising either hexagonally packed pores (HX) or a disordered pore arrangement (CF). The sorbents were functionalized with combinations of two types of alkylammonium groups. When capture of perchlorate by the sorbents was compared, widely varying performance was noted as a result of differing morphology and/or functional group loading. A material providing improved selectivity for perchlorate over perrhenate was synthesized with a CF material using <i>N</i>-trimethoxysilylpropyl-<i>N</i>,<i>N</i>,<i>N</i>-trimethylammonium chloride. Materials were applied in batch and column formats. Binding isotherms followed the behavior expected for a system in which univalent ligands of varying affinity compete for immobilized sites. Performance of the sorbents was also compared to that of commercial Purolite materials.
Methanogen Diversity Evidenced by Molecular Characterization of Methyl Coenzyme M Reductase A ( <i>mcrA</i> ) Genes in Hydrothermal Sediments of the Guaymas Basin (2005)

The methanogenic community in hydrothermally active sediments of Guaymas Basin (Gulf of California, Mexico) was analyzed by PCR amplification, cloning, and sequencing of methyl coenzyme M reductase (mcrA) and 16S rRNA genes. Members of the Methanomicrobiales and Methanosarcinales dominated the mcrA and 16S rRNA clone libraries from the upper 15 cm of the sediments. Within the H2/CO2- and formate-utilizing family Methanomicrobiales, two mcrA and 16S rRNA lineages were closely affiliated with cultured species of the genera Methanoculleus and Methanocorpusculum. The most frequently recovered mcrA PCR amplicons within the Methanomicrobiales did not branch with any cultured genera. Within the nutritionally versatile family Methanosarcinales, one 16S rRNA amplicon and most of the mcrA PCR amplicons were affiliated with the obligately acetate utilizing species Methanosaeta concilii. The mcrA clone libraries also included phylotypes related to the methyl-disproportionating genus Methanococcoides. However, two mcrA and two 16S rRNA lineages within the Methanosarcinales were unrelated to any cultured genus. Overall, the clone libraries indicate a diversified methanogen community that uses H2/CO2, formate, acetate, and methylated substrates. Phylogenetic affiliations of mcrA and 16S rRNA clones with thermophilic and nonthermophilic cultured isolates indicate a mixed mesophilic and thermophilic methanogen community in the surficial Guaymas sediments.

Constant envelope precoding for secure millimeter-wave wireless communication (2017)

This paper exploits the potential of large antenna arrays to develop a secure millimeter wave (mmwave) transmission scheme. To reduce the peak-to-average power ratio (PAPR), the idea of constant envelope precoding (CEP) is introduced to improve the power efficiency of power amplifiers. In the CEP scheme, only phase variation of each antenna is used to form the desired signal at the target receiver, while the sum power of noise-free signals received by all eavesdroppers is minimized for secure transmission. A nonconvex optimization problem is formulated with equality and unit modulus constraints. To tackle the nonconvex constraints, the augmented Lagrangian penalty method is employed to address the challenging problem. An efficient iterative algorithm is further proposed to tackle the problem of precoder design. Simulation results confirm the effectiveness and superiority of the proposed CEP secure transmission scheme.
Comparative Studies of Baculovirus Granulins and Polyhedrins (1975)

Granulins and polyhedrins from five baculoviruses exhibit similar chemical and physical properties. Although similarities are demonstrated, it has been shown that each of the proteins is different and apparently specific to a given virus. The granulins and polyhedrins exhibit a major polypeptide component of an estimated molecular weight of 28,000. Alkaline protease activity has been detected in each preparation. N-terminal analyses reflect differences between granulins and polyhedrins studied: granulosis virus = Asx, and nuclear polyhedrosis virus = Glx. Two-dimensional high-voltage electrophoresis of highly purified granulin and polyhedrin preparations reveals relatedness as well as differences among the proteins as assessed by electrophoretic migration patterns.
