Enumerating Injured Coliforms in Drinking Water (1985)

This article emphasizes the importance of enumerating injured coliforms in drinking water and reviews the sources of injury, factors influencing the extent of injury, problems in enumerating stressed coliforms, recent advances in enumeration techniques, and the health implications of injured coliforms. Recommendations regarding future research are included.
Glycosylation status of endogenous CFTR does not affect cAMP-stimulated Cl- secretion in epithelial cells (1993)

Cystic fibrosis (CF) impairs Cl- secretion across epithelial tissues and is caused by mutations in an N-linked glycoprotein, the cystic fibrosis transmembrane conductance regulator (CFTR). We modified the glycosylation pattern of CFTR using inhibitors of oligosaccharide processing and determined their effects on both agonist-induced Cl- secretion and CFTR location in human colon (HT-29) cell lines. In both polarized and unpolarized HT-29 cells, immunoprecipitation of cell extracts using a monoclonal antibody against CFTR gave a single band at 170 kDa. Inhibitors of N-linked glycosylation reduced the molecular mass of this band: swainsonine by 10 kDa, deoxymannojirimycin by 30 kDa, and deoxynojirimycin by 10-20 kDa. However, the transepithelial Cl- current and conductance stimulated by adenosine 3',5'-cyclic monophosphate (cAMP)- or Ca(2+)-dependent secretagogues was not affected. In the polarized cells, CFTR was localized in the apical membrane domain. Treatment of the monolayers with glycoprocessing inhibitors did not affect CFTR's location. Thus, in human colonocytes that endogenously express CFTR, the extent of CFTR glycosylation does not influence the targeting of CFTR to the apical membrane domain or its function as an agonist-stimulated Cl- channel.
Leaky-Wave Antenna and Band-Reject Filter for Millimeter-Wave Integrated Circuits (2005)

Grating structures fabricated in inverted strip dielectric waveguide have for the first time been used as millimeter-wave leaky-wave antennas and band-reject filters. Experimental results agree reasonably well with theoretical predictions.
Generalization of Wigner Time Delay to Sub-Unitary Scattering Systems (2021)

We introduce a complex generalization of Wigner time delay $τ$ for sub-unitary scattering systems. Theoretical expressions for complex time delay as a function of excitation energy, uniform and non-uniform loss, and coupling, are given. We find very good agreement between theory and experimental data taken on microwave graphs containing an electronically variable lumped-loss element. We find that time delay and the determinant of the scattering matrix share a common feature in that the resonant behavior in $\text{Re}[τ]$ and $\text{Im}[τ]$ serves as a reliable indicator of the condition for Coherent Perfect Absorption (CPA). This work opens a new window on time delay in lossy systems and provides a means to identify the poles and zeros of the scattering matrix from experimental data. The results also enable a new approach to achieving CPA at an arbitrary energy/frequency in complex scattering systems.
I. Advanced Fluorescent False Neurotransmitters for the Study of Monoamine Transporter Activity and Synaptic Transmission (2013)

This thesis details two projects at the interface of chemistry and neuroscience. Part I focuses on the development and characterization of fluorescent optical tracers of monoamine neurotransmitters for use in the study of monoamine transporter activity and distribution, as well as synaptic transmission in the brain. The second section details early studies concerning experimental therapeutics recently identified by our group to induce the synthesis and release of Glial Derived Neurotrophic Factor (GDNF) from a model astroglial cell line. Part I consists of Chapters 1-5. Chapter 1 provides a brief introduction to the relationship between chemistry and neuroscience, while explaining the motivation and background behind the development and study of Fluorescent False Neurotransmitters (FFNs). Chapter 2 discusses the characterization of new fluorescent substrates for the Vesicular Monoamine Transporter 2 (VMAT2) for applications in high throughput screening of VMAT activity and inhibition, as well as for imaging aminergic synaptic transmission in brain tissue. Chapter 3 describes the discovery of fluorescent probes FFN201 and AGH093 as dual substrates for the norepinephrine transporter (NET) and VMAT, with potential applications in the imaging of noradrenergic modulation of cortical signaling networks. NG54, a FFN with substrate activity at each of the monoamine transporters was also identified, and represents a new structural class of FFNs. In Chapter 4, APP+, a known fluorescent substrate for the monoamine transporters, is evaluated as a potential tracer of monoamines in the brain. It has been determined that while this molecule may have utility as a marker for monoaminergic neurons, APP+ is not an appropriate FFN due to high background labeling of mitochondria and other intracellular structures. Chapter 5 discusses the discovery of fluorescent substrates of the Organic Cation Transporter 3 (OCT3) and Plasma Membrane Monoamine Transporter (PMAT). Mounting evidence suggests that these transporters play a significant role in clearing extracellular space of monoamines and are likely involved in neurological disease. As such, fluorescent substrates of OCT3 or PMAT would be useful as imaging agents in the brain, as well as for the development of fluorescence-based quantitative inhibition assays. Part II of this thesis (Chapter 6) discusses N-arylethyl isoquinuclidines as releasers of glial cell line-derived neurotrophic factor (GDNF) from a model glial cell line. Initial characterization of GDNF release and its dependence on protein synthesis and MAPK/ERK signaling is described. Preliminary studies indicate that at least two experimental compounds described herein modulate fibroblast growth factor receptor (FGFR) signaling.
Line-scan focal modulation microscopy for rapid imaging of thick biological specimens (2011)

In recent development of fluorescence microscopy, the out-of-focus fluorescence background that arises when imaging deep inside biological tissues is critical in determining the image quality and penetration depth. Focal Modulation Microscopy [1–3] (FMM) is an emerging single-photon excitation fluorescence microscopy technique that can provide sub-micron spatial resolution for deep imaging of biological tissues mainly by preserving the signal-to-background ratio. Here we report a line-scan FMM that enables line-by-line recording [4] at video frame rates (&gt;30 fps) depending on the size of region of interest.
Invocation of real-time objects in a CAN bus-system (2002)

The paper focuses on method invocation of real-time objects in a CAN-based distributed real-time system. A simple object model is introduced, which allows the convenient modelling of hardware and software components. Related to the object model, two issues are discussed. Firstly, a model is introduced which allows to form and address object groups. This reflects a basic need in a real-time system to distribute information to multiple clients efficiently. Secondly, the paper discusses an approach to express timing requirements for object invocations. To achieve distributed consensus on communication resource access, an EDF-like approach is introduced, which takes advantage of knowledge about deadlines, the number of remaining communication activities and the remaining worst-case execution time for the invoked method at each point of time.
The Genomic Sequence of the Oral Pathobiont Strain NI1060 Reveals Unique Strategies for Bacterial Competition and Pathogenicity (2016)

Strain NI1060 is an oral bacterium responsible for periodontitis in a murine ligature-induced disease model. To better understand its pathogenicity, we have determined the complete sequence of its 2,553,982 bp genome. Although closely related to Pasteurella pneumotropica, a pneumonia-associated rodent commensal based on its 16S rRNA, the NI1060 genomic content suggests that they are different species thriving on different energy sources via alternative metabolic pathways. Genomic and phylogenetic analyses showed that strain NI1060 is distinct from the genera currently described in the family Pasteurellaceae, and is likely to represent a novel species. In addition, we found putative virulence genes involved in lipooligosaccharide synthesis, adhesins and bacteriotoxic proteins. These genes are potentially important for host adaption and for the induction of dysbiosis through bacterial competition and pathogenicity. Importantly, strain NI1060 strongly stimulates Nod1, an innate immune receptor, but is defective in two peptidoglycan recycling genes due to a frameshift mutation. The in-depth analysis of its genome thus provides critical insights for the development of NI1060 as a prime model system for infectious disease.
Conversion of light hydrocarbon gases to metal carbides for production of liquid fuels and chemicals. Quarterly technical progress report, January 1--March 31, 1995 (1995)

The methane plasma stabilization problem was resolved with the reconfiguration of the DC power supply to give a higher open circuit voltage to enable operation of the arc at higher voltage levels and with the installation of a solenoid around the plasma reactor to magnetically rotate the are. Cathode tip erosion problems were encountered with the 1/4-inch graphite and tungsten tips which necessitated a redesign of the plasma reactor. The new plasma reactor consists of an enlarged 3/4-inch O.D. graphite tip to reduce current density and a 1-inch I.D. graphite anode. Products from MgO/CH{sub 4} scoping runs in the redesigned reactor under conditions of excess MgO gave strong indications that a breakthrough has finally been achieved i.e. that synthesis of magnesium carbides from MgO and methane in the arc discharge reactor has been demonstrated. Significant quantities of hydrocarbons, primarily C{sub 3}H{sub 4} and C{sub 2}H{sub 2}, were detected in the headspace above hydrolyzed solid samples by GC analysis. In one run, solids glowed upon exposure to the atmosphere, strongly suggesting carbide reaction with moisture in the air, exothermically forming acetylenes which ignited instantaneously in the presence of oxygen and elevated temperatures arising from localized heat-up of the specimens.

Testing a generalized domain model of photodegradation and self-healing using novel optical characterization techniques and the effects of an applied electric field (2013)

Reversible Photodegradation is a relatively new phenomenon which is not well understood.Previous research into the phenomenon has focused primarily on nonlinear measurements such as amplified spontaneous emission (ASE) and two-photon fluorescence (TPF).We expand on this research by considering linear optical measurements, such as transmittance imaging and absorption spectroscopy, of disperse orange 11 (DO11) dye-doped (poly)methyl-methacralate (PMMA) thin films and find photodegradation to contain both a reversible component and irreversible component, with the irreversible component having a small nonlinear susceptibility.From absorption measurements, and the small nonlinear susceptibility of the irreversible component, we hypothesize that the reversible component corresponds to damage to the dye, and the irreversible component is due to damage to the polymer host.Also, we develop models of depth dependent photodegradation taking pump beam absorption and propagation into account.We find that pump absorption must be v taken into account, and that ignoring the effect leads to an underestimation of the true decay rate and degree of damage.In addition, we find pump propagation effects occur on large length scales, such that they are negligible when compared to absorption and typical sample thicknesses.Finally, we perform electric field dependent reversible photodegradation measurements and find that the underlying mechanism of reversible photodegradation is sensitive to the dye-doped polymer's electrical properties.We develop an extension to the correlated chromophore domain model to include the effect of an applied field, and find the model to fit experimental data for varying intensity, temperature, and applied electric field with only one set of model parameters.vi
An adaptive crossover distribution mechanism for genetic algorithms (1987)

Two recruitment strategies for research were compared to prospectively identify patients with breathlessness who are awaiting a diagnosis in primary care. The first method utilised searches of the electronic patient record (EPR), the second method involved an electronic template triggered during a consultation. Using an electronic template triggered at the point of consultation increased recruitment to prospective research approximately nine-fold compared with searching for symptom codes and study mailouts.
Conception d’un atténuateur de houle de type caisson à double parois poreuses (2014)

La rnovation du vieux port de Cannes a incit la CCI Nice Cte d'Azur tenter d'amliorer le confort du port, altr depuis la construction en 1995 d'un mur de parking rflchissant la houle au fond du bassin. Le besoin de restructurer entirement le ponton Pantiero, implant au milieu du bassin, tait aussi l'occasion d'apporter de la dissipation supplmentaire travers la conception d'un nouvel ouvrage. Parmi les solutions appropries, le caisson Jarlan prsentait des avantages indniables. Les tudes hydrodynamiques classiques en agitation portuaire ont mis en vidence l'intrt de concevoir un attnuateur double flux, se comportant comme un caisson Jarlan en termes de rflexion des houles incidentes dominantes, mais autorisant une certaine transmission d'nergie. Cela se traduit par le remplacement de la paroi habituellement opaque en fond de Jarlan par une paroi faiblement poreuse, laquelle vite les rflexions totales l'aval de l'ouvrage et limite les rsonances par rflexions entre deux parois verticales dans un port. Des simulations en interaction houle-structure intgrant les effets de pertes de charge travers des plaques poreuses ont permis de cerner l'ouvrage en phase de conception. Les paramtres de dimensionnement ont ensuite t valids en canal houle dans le cadre des tudes d'excution de l'ouvrage construit en 2013.
[<sup>18</sup>F]-Fluorodeoxyglucose (FDG) and Positron Emission Tomography (PET) in Aging and Dementia (1989)

Alzheimer's disease (AD) is becoming an increasingly important public health problem. The clinical diagnosis of AD continues to be problematic and costly. [18F]-fluorodeoxyglucose-position emission tomography (FDG-PET) can assist with the diagnosis of AD at an early stage. The utility of FDG-PET in AD may also be extremely useful in the future when objective physiologic monitoring of drug effects and therapy are required.

산소(δ 18 O)와 질소(δ 15 N) 안정동위원소비를 이용한 상수원의 오염원 분석 (2017)

The use of chemical analyses for water quality management has limitations in terms of efficiently managing pollutants through various pollutants sources. For the purpose of identification, stable isotope ratio methods are wildly used around world. The measurement technique of oxygen and nitrogen stable isotopes in water is employed to establish the origin and pollution source in the water quality protection area in this study. The target study areas, which are a water resource, is located in G area, Korea, and the analytical samples were collected 4 times per year at 5 sites. As a result, the assigned values of oxygen and nitrogen stable isotopes in water were changed based on rainfall. The target area, water quality protection area, was estimated to be highly influenced by soil from land, manure and sewage, and contaminated groundwater. According to the correlation between oxygen and nitrogen stable isotope ratio, the study area is estimated to be influenced by pollution sources in D site, where inflow was not large.
Torasemide versus furosemide in treatment of heart failure: A systematic review and meta‐analysis of randomized controlled trials (2019)

Although not all results are statistically significant, torasemide has potential advantages on multiple aspects of HF management when compared with furosemide. More studies are needed to clarify these effects.
A Design of Self-Tuning PID Controllers Based on the Generalized Minimum Variance Control Law (1998)

Self-tuning control schemes need many control parameters corresponding to the order and the time-delay of the controlled object. Using such many control parameters yields the inferiority in the transient property. Therefore, in order to design practical self-tuning controllers, it is seemed that it is desirable to construct control systems with as few parameters as possible.In this paper, we propose a method how to tune PID parameters adaptively, that is, a self-tuning PID control scheme, based on the relationship between a generalized minimum variance control (GMVC) law and a PID control law. Furthermore, we consider a design scheme of user-specified parameters included in the cost function of the GMVC. Finally, we apply the proposed scheme to an air pressure control system in order to investigate the effectiveness.
Distribution ofTcfrom calorimetry and the determination of Sn gradients in bronze route Nb3Sn wires with an internal and external Ti source (2007)

We have investigated the influence of two different Ti doping methods on the superconducting properties of bronze route Nb3Sn multifilamentary wires. The first doping method introduces NbTi rods into NbTa filaments embedded in a Cu15.4Sn bronze matrix ('internal' Ti). The second method uses Cu15.5Sn0.25Ti bronze as an external source of Ti ('external' Ti). The wires prepared by 'external' Ti doping were found to exhibit the highest critical current values although the conductor configurations were identical.
On the Modeling and Diagnosis of a Micro-Structured Wire Antenna System (2018)

Micro-structured systems of wire antennas the inter-element distance of which being much smaller than the electromagnetic wavelengths either in transmission or reception are studied by the authors from 3-D computational modeling to experiments in anechoic chambers on down-scaled prototypes. Recent results with focus on potential super-localization of a peculiar radiating element in the aforementioned micro-structure will be considered here while further challenges ahead, notably in terms of questions of super-resolved imaging in likewise microstructured structures will be sketched.
Transient photoconductivity in selectively dopedn-typeAlxGa1−xAsGaAsheterostructures (1984)

A new kind of transient photoconductivity (TPC) at low temperatures (4.2 K) in addition to the persistent photoconductivity was found in selectively doped $n$-type $\frac{{\mathrm{Al}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{As}}{\mathrm{GaAs}}$ heterostructures with high-mobility two-dimensional electron gas (2D EG). A model is presented for the transient part of the 2D EG carrier concentration. The decay of the carrier concentration is analyzed in terms of tunneling-assisted electron-trap recombination, and a good agreement between measured and calculated time dependence of the carrier concentration is obtained. Comparison of theory and experiments yields valuable information on the trap responsible for the TPC effect. Our evaluation technique allows us to determine quantitatively the concentration of that specific deep trap and is, therefore, a versatile tool for the characterization of selectively doped heterojunctions and for an improved understanding of their unique physical properties.
Understanding Interlayer Coupling in TMD-hBN Heterostructure by Raman Spectroscopy (2018)

In 2-D van der Waals heterostructures, interactions between atomic layers dramatically change the vibrational properties of the hybrid system and demonstrate several interesting phenomena that are absent in individual materials. In this paper, we have investigated the vibrational properties of the heterostructure between transition metal dichalcogenide (TMD) and hexagonal boron nitride (hBN) on gold film at low- and high-frequency ranges by Raman spectroscopy. Nineteen Raman modes have been observed from the sample, including a new interlayer coupling mode at 28.8 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> . Compared to reported experimental results of tungsten disulfide (WS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) on SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> /Si substrates, the Raman spectrum for WS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> on hBN/Au emerges a blue shift of about 8 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> . Furthermore, a remarkable enhancement of Raman intensity can be obtained when tuning hBN thickness in the heterostructure. Through systematic first-principles calculations, numerical simulations, and analytical calculations, we find that the 28.8 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> mode originates from the shearing motion between monolayer TMD and hBN layers. In addition, the gold substrate and hBN layers form an optical cavity and the cavity interference effects enhance the obtained Raman intensity. This paper demonstrates the novel vibrational modes of 2-D van der Waals heterostructure as an effective tool to characterize a variety of such heterostructures and reveals a new method to enhance the Raman response of 2-D materials.
