Acid-Susceptible Mutants of<i>Mycobacterium tuberculosis</i>Share Hypersusceptibility to Cell Wall and Oxidative Stress and to the Host Environment (2008)

Mycobacterium tuberculosis can persist in macrophage phagosomes that acidify to a pH of approximately 4.5 after activation of the macrophage with gamma interferon. How the bacterium resists the low pH of the acidified phagosome is incompletely understood. A screen of 10,100 M. tuberculosis transposon mutants for mutants hypersensitive to pH 4.5 led to the discovery of 21 genes whose disruption attenuated survival of M. tuberculosis at a low pH (41). Here, we show that acid-sensitive M. tuberculosis mutants with transposon insertions in Rv2136c, Rv2224c, ponA2, and lysX were hypersensitive to antibiotics, sodium dodecyl sulfate, heat shock, and reactive oxygen and nitrogen intermediates, indicating that acid resistance can be associated with protection against other forms of stress. The Rv2136c mutant was impaired in intrabacterial pH homeostasis and unable to maintain a neutral intrabacterial pH in activated macrophages. The Rv2136c, Rv2224c, and ponA2 mutants were attenuated in mice, with the Rv2136c mutant displaying the most severe level of attenuation. Pathways utilized by M. tuberculosis for acid resistance and intrabacterial pH maintenance are potential targets for chemotherapy.
A polymerase chain reaction-based method to detect cisplatin adducts in specific genes (1991)

Every bulky lesion in DNA can potentially inhibit the Taq DNA polymerase and thereby decrease the amplification produced in the polymerase chain reaction. We investigated the feasibility of using this inhibition to quantify DNA lesions produced by the anticancer drug cisplatin. Products were detected by electrophoresis followed by ethidium bromide staining. Quantitation was obtained by including [32P]dCTP in the amplification reaction and subsequently assessing the incorporated radioactivity. Hamster genomic DNA was platinated in vitro to defined levels and amplified with primers that produce either a 150, 750 or 2,000 base pair fragment. The degree of inhibition of PCR agreed with the predicted level of DNA platination in each size of fragment, suggesting that the polymerase was inhibited by every cisplatin-induced lesion. This method was used to detect cisplatin-induced lesions in the adenine phosphoribosyltransferase gene of CHO cells. Cells were incubated with 0-125 microM cisplatin for 2 h, the DNA was purified and subjected to PCR. A significant decrease in amplification of the 2 kbp fragment was observed in DNA from cells incubated with cisplatin at 75 microM. The degree of inhibition agreed closely with the amount of DNA damage in the overall genome as measured by atomic absorption. No change was detected in amplification of the 150 base fragment which can therefore be used to normalize data for any variations between DNA samples. This assay has the same sensitivity as other methods currently used for the analysis of gene-specific damage. The advantage of this assay is that it obviates the need for specific endonuclease complexes to recognize and cleave DNA adducts as previously required when analyzing damage in specific genomic sequences.
Induction of resistance to mineralocorticoid hormone in cultured inner medullary collecting duct cells by TGF-beta 1 (1994)

The renal collecting duct is a major target for the mineralocorticoid hormone aldosterone which acts to enhance electrogenic Na+ absorption. The cortical portion of the collecting duct displays a vigorous response to mineralocorticoids administered in vivo. The terminal, or inner medullary portion, does not usually display such a vigorous response; the reason for this difference is unknown. To explore one possible mechanism for this lack of response, we varied the conditions of culturing these cells and determined that serum inhibited the ability of aldosterone to enhance Na+ transport. By screening 11 peptides, we found that transforming growth factor (TGF)-beta 1 produced a concentration-dependent inhibition of the action of aldosterone. The action of TGF-beta 1 required at least several hours of incubation. Resistance to the action of aldosterone could be produced by preincubating the monolayers with TGF-beta 1 for a few hours; subsequent exposure to aldosterone for up to 48 h failed to stimulate Na+ transport. TGF-beta 1 did not produce a change in cell morphology or the content of DNA, ATP, or ADP; there was a small reduction in protein content. Pretreatment with cycloheximide failed to reproduce the TGF-beta 1 effect. The induction of resistance to mineralocorticoid hormone may play an important role in modulating the effects of aldosterone on Na+ homeostasis.

Development of Sustainable Cold Spray Coatings and 3D Additive Manufacturing Components for Repair/Manufacturing Applications: A Critical Review (2017)

This review article presents the findings of a comprehensive state-of-the-art literature review of the scientific and technological progress of the cold spray process in the field of repair/remanufacturing using the concept of additive manufacturing. A thorough study was conducted on the potential of this technology to form (a) both thin and thick coatings; (b) the ability to fabricate 3D freeform components in a single process, while benefiting from reduced residual stress level compared to conventional thermal spray coatings processes such as high velocity oxy-fuel (HVOF) or plasma spraying. A systematic overview of the process technology, particularly focusing on the suitability of ceramic-metallic (cermet) composite particles used as feedstock in the deposition was conducted; further elaboration was made pertinent to particle impact and bonding mechanisms during the deposition.
Femtosecond ultrashort pulse generation by addition of positive material dispersion (2010)

We demonstrate femtosecond ultrashort pulse generation by adding further positive group velocity dispersion (GVD) to compensate for the presence of positive GVD. The idea is based on the integer temporal Talbot phenomenon. The broad Raman sidebands with a frequency spacing of 10.6 THz are compressed to form a train of Fourier-transform-limited pulses by passing the sidebands through a device made of dispersive material of variable thickness.
The United Nations Convention against Corruption (2011)

Corruption has been recognised as a global problem affecting both the developing and the developed world. The United Nations Convention against Corruption (UNCAC) is the first legally binding, global anti-corruption instrument. The UNCAC covers a broad range of anti-corruption activities, including the four main areas of prevention, criminalisation and law enforcement, international cooperation, and asset recovery. It has attracted overwhelming support from UN Member states, with over 140 parties to the Convention. Support for implementing this Convention is provided by the United Nations Office on Drugs and Crime (UNODC), which serves as the Secretariat to the Conference of States Parties to the UNCAC.
Decision-making in elderly patients with severe aortic stenosis: why are so many denied surgery? (2005)

Surgery was denied in 33% of elderly patients with severe, symptomatic AS. Older age and LV dysfunction were the most striking characteristics of patients who were denied surgery, whereas comorbidity played a less important role.
Block-Oriented Systems Simulator (BOSS) (1986)

The Block-Oriented Systems Simulator (BOSS) may be viewed as an operating system that provides a complete interactive environment for simulation-based analysis and design of communication systems. The integrated environment includes the capability to design models, subsystems and systems in a hierarchical fashion using block diagrams, configure and execute a simulation, review the results of the simulation, and perform design iterations. Each of these capabilities is controlled through a consistent user interface using interactive graphics. Recent advances in software engineering, workstation technology, CAD/CAM techniques and expert systems are incorporated in BOSS to provide an intelligent, user friendly and flexible state-of-the-art simulation environment.
MESH-BASED CATHODIC DECK PROTECTION (1988)

In order to protect the concrete bridge deck reinforcing bars from corrosion, a cathodic protection system employing an anode mesh was installed and activated on the Jones Falls Expressway, Baltimore, Maryland. It is expected that the installation will eliminate the need for cyclical patching of the deck, and lengthen the deck's service life. The system employed is based on proprietary technology that employs a precious metal oxide catalyst that prevents damage to surrounding concrete. The titanium anode substrate employed as an electrical conductor has low electrical resistance, chemical stability, and in mesh form offers great redundancy of available electrical paths. Also, the anode mesh is compatible within its concrete environment. The system is expected to give protection from corrosion for 25 years.
ALGUNAS REFLEXIONES EPISTEMOLÓGICAS SOBRE LA INVESTIGACIÓN CUALITATIVA (2009)

En el presente articulo y con base en el analisis de trabajos teoricos, reportes empiricos de investigacion cualitativa y nuestra propia experiencia, nos aproximamos a compartir algunos elementos que hemos aprehendido a lo largo de la trayectoria educativa – investigativa, especialmente, como tutoras de pregrado en la linea de la epistemologia cualitativa. No pretendemos con esto, plantear como hacer investigacion cualitativa, esta no se decreta, se construye en convivencia; por el contrario, solo deseamos narrar nuestras propias trayectorias, recorridos y caminos seguidos en el area de la investigacion social desde la mirada intersubjetiva de la realidad social. En tal sentido, consideramos necesario un cambio paradigmatico en las ciencias sociales centrado en una epistemologia que permita la recuperacion del sujeto social en su contextualidad.
Feature Extraction Techniques for Sorting Tomatoes by Computer Vision (1985)

ABSTRACT SPECIAL algorithms were developed using digital image analysis and pattern recognition techniques for orientation of fresh market tomatoes and classification based on size, shape, color and surface defects. Performance testing of the classification algorithms demonstrated the feasibility of applying computerized visual inspection to tomatoes.
Pharmaceutical organogels prepared from aromatic amino acid derivatives (2009)

Organogels are semi-solid systems in which an organic liquid phase is immobilized by a 3-dimensional network composed of self-assembled gelator molecules. Although there is a large variety of organogel systems, relatively few have been investigated in the field of drug delivery, owing mostly to the lack of information on their biocompatibility and toxicity. In this work, organogelator-biocompatible structures based on aromatic amino acids, namely, tyrosine, tryptophan, and phenylalanine were synthesized by derivatization with aliphatic chains. Their ability to gel an injectable vegetable oil (<i>i.e.</i> safflower oil) and to sustain the release of a model anti-Alzheimer drug (<i>i.e.</i> rivastigmine) was then evaluated. Organogels and molecular packing were characterized by differential scanning calorimetry, rheology analysis, Fourier-transform infrared spectroscopy and X-ray crystallography. The amino acid derivatives were able to gel safflower oil through van der Waals interactions and H-bonds. Tyrosine-derivatives produced the strongest gels while tryptophan was associated with poor gelling properties. The superior gelling ability of tyrosine derivatives could be explained by their well-structured 2-dimensional packing in the network. The addition of an optimal <i>N</i>-methyl-2-pyrrolidone amount to tyrosine gels fluidized the network and allowed their injection through conventional needles. Upon contact with an aqueous medium, the gels formed <i>in situ</i> and released entrapped rivastigmine in a sustained fashion.
Infinite Length Results and Design Implications for Time-Domain Equalizers (2004)

We show that maximum shortening signal-to-noise ratio (SNR) time-domain equalizers (TEQs) are often nearly symmetric. Constraining the TEQ to be symmetric causes only a 3% loss in bit rate (averaged over eight standard ADSL channels). Symmetric TEQs have greatly reduced design and implementation complexity. We also show that for infinite length TEQs, minimum mean squared error (MMSE) target impulse responses have all zeros on the unit circle, which can lead to poor bit rate performance.
Detection of<i>Salmonella enterica</i>Serovar Typhimurium by Using a Rapid, Array-Based Immunosensor (2004)

The multianalyte array biosensor (MAAB) is a rapid analysis instrument capable of detecting multiple analytes simultaneously. Rapid (15-min), single-analyte sandwich immunoassays were developed for the detection of Salmonella enterica serovar Typhimurium, with a detection limit of 8 x 10(4) CFU/ml; the limit of detection was improved 10-fold by lengthening the assay protocol to 1 h. S. enterica serovar Typhimurium was also detected in the following spiked foodstuffs, with minimal sample preparation: sausage, cantaloupe, whole liquid egg, alfalfa sprouts, and chicken carcass rinse. Cross-reactivity tests were performed with Escherichia coli and Campylobacter jejuni. To determine whether the MAAB has potential as a screening tool for the diagnosis of asymptomatic Salmonella infection of poultry, chicken excretal samples from a private, noncommercial farm and from university poultry facilities were tested. While the private farm excreta gave rise to signals significantly above the buffer blanks, none of the university samples tested positive for S. enterica serovar Typhimurium without spiking; dose-response curves of spiked excretal samples from university-raised poultry gave limits of detection of 8 x 10(3) CFU/g.
Synthesis of SAPO-34 Molecular Sieves and Their Catalytic Performances in Methanol-to-Olefins Reaction (2010)

SAPO-34 molecular sieves were synthesized hydrothermally.The effects of templates,template amounts,pH,crystallization temperature and time on the synthesis were investigated.By means of XRD,SEM,BET and NH_3-TPD techniques,the influences of the molecular sieve structure and surface acidity on the catalytic properties were also studied.The results show that compared with DEA,TEA and TMAOH,TEAOH is the most proper template for synthesis of SAPO-34 with large BET surface areas(400 m~2/g),homogeneous cubic crystals of narrow size distribution and proper ratio of strong to weak acid sites,while the SAPO-34 prepared by using DEA as template shows strongger acidity. Using TEAOH as template with its amount in the range of n(TEAOH)∶n(Al_2O_3) of 2.02-1.35,the crystallinity of product SAPO-34 decreases upon reducing the amount of template.Reducing TEAOH amount in the range of n(TEAOH)∶n(Al_2O_3) of 1.35-1.01 leads to SAPO-5 cogenerating with SAPO-34.A directly fast heating is unfavorable for the growth of crystals.The procedure of preheating to 90-150 ℃,keeping this temperature until the transition state becomes stable and then heating to 170-250 ℃ for crystallization is favorable for the synthesis of SAPO-34 with higher crystallinity which shows the best catalytic performances with a 100% methanol conversion,a selectivity of 83.40% for C~=_2-C~=_3,and a life time of 220 min.
Polens Katholizismus und die europäische Integration (2000)

Der Verfasser untersucht das Verhältnis der katholischen Kirche in Polen zur Vollmitgliedschaft Polens in der EU differenziert für das Episkopat, den Klerus sowie den politischen Katholizismus und die Laienorganisationen. Die Mehrheit der polnischen Bischöfe milderte ihre sehr reservierte Haltung zu einer EU-Mitgliedschaft Polens erst in der zweiten Hälfte der 90er Jahre ab. In der Priesterschaft bestehen weniger Vorbehalte als im Episkopat. Auch die einflussreiche nationalkatholische Strömung und ihre Organisation 'Christlich-Nationale Vereinigung' (ZChN) vollzog eine Wende zu einer pragmatischeren Haltung. Im Netzwerk der Laienorganisationen ist das Bild noch uneinheitlich. Insgesamt kann das Klima im polnischen Katholizismus nicht als durchgängig europafreundlich beschrieben werden. (ICE2)
Acute lymphoblastic leukemia (ALL) antigens detected with antisera to E rosette-froming and non-E rosette-forming ALL blasts. (1977)

Based on the presence or absence of erythrocyte receptors(E) a T cell marker, acute lymphocytic leukemia (ALL), can be divided into E+ALL and E-ALL. We studied cell surface antigens on blasts from 12 children with untreated ALL: eight with E-ALL and four with E+ALL. Heterologous antisera were raised against thymus cells, E+ and E-ALL blasts, appropriately absorbed and tested by immunofluorescence and a radiolabeled antibody assay with normal and leukemic lymphoid cells. By both methods, anti-thymus and anti-E+ALL sera reacted with human thymocytes. Specific binding of anti-E+ALL serum to T antigens was indicated by the fact that a single absorption with thymocytes abolished its binding to allogenic thymocytes, and the reactivity of anti-E+ALL serum with thymus, blood and bone marrow lymphocytes was similar to that of anti-thymus serum. After exhaustive absorption with blood leukocytes, anti-E+ALL and E-ALL sera were negative against normal lymphocytes and bone marrow cells from children with ALL in remission. Anti-thymus and anti-E+ALL sera reacted with blasts from patients with E+ALL, but not with E-ALL. In contrast, anti-E+ALL serum reacted with 40 to 96% of blasts from all children with E-ALL, whereas of the four patients with E+ALL, two were negative and two had the lowest percentage of immunofluorescent cells (10 to 22%). These results were confirmed with the radiolabeled antibody assay. Patients with active E-ALL had cells bearing E-ALL antigen(s) in the peripheral blood and bone marrow, but the number of immunofluorescent cells was lower in blood. Cells reactive with anti-E-ALL serum did not react with thymus cells, blood lymphocytes, remission bone marrow cells, Raji cells, PWM and PHA-induced blasts and CLL cells bearing mIg (uk). These data suggest that the antigen detected on E-ALL blasts by anti-E-ALL serum is neither a HLA-related nor a cell differentiation antigen. Thus, by using antiserum to E+ALL blasts, we have confirmed the presence of a T cell-specific antigen(s) on E+ALL cells. This antiserum did not recognize other leukemia-associated antigens common to E+ and E-ALL. We have also demonstrated an antigen(s) which is regularly expressed on E-ALL blasts and is either not detectable or is present in a lower proportion of E+ALL blasts.
<title>Coherent techniques and digital-micromirror-device-based switched photonic time delay control for high-frequency antenna arrays</title> (1997)

Two photonic delay line structures are introduced that are based on the binary operation of Digital Micromirror DEvices (DMDs). These structures include a binary switched design based on multiple DMDs, and a non-binary delay line using a single DMD. These DMD-based delay lines do not require polarized light for operation.
Mood variations decoded from multi-site intracranial human brain activity (2018)

The ability to decode mood state over time from neural activity could enable closed-loop systems to treat neuropsychiatric disorders. However, this decoding has not been demonstrated, partly owing to the difficulty of modeling distributed mood-relevant neural dynamics while dealing with the sparsity of mood state measurements. Here we develop a modeling framework to decode mood state variations from multi-site intracranial recordings in seven human subjects with epilepsy who self-reported their mood state intermittently over multiple days. We built dynamic neural encoding models of mood state and corresponding decoders for each individual and demonstrated that mood state variations over time can be decoded from neural activity. Across subjects, the decoders largely recruited neural signals from limbic regions, whose spectro-spatial features were tuned to mood variations. The dynamic models also provided an analytical tool to compute the timescales of the decoded mood state. These results provide an initial line of evidence indicating the feasibility of mood state decoding.
Large high resolution display systems via tiling of projectors (2003)

The most important contributor today to the increasing realism of training simulators – and more specifically flight simulators – is simulation projection technology. As Image Generators (IG’s) have become more and more powerful and affordable, simulation imagery has reached a very high degree of realism through a combination of high resolution and image complexity. The combination of large fields of view and high image resolutions result in pixel counts that far exceed the ability of a single projection display. For example, a hemispherical display of 2pi steradians requires approximately 95Mpixels for 1arc-min spot resolution. It is therefore necessary to devise techniques to seamlessly tile images from multiple projectors. This paper discusses the difficulties in tiling multiple projectors and the methods currently used to overcome them. Large field of view images exhibit geometric distortions caused by system optics, projector misalignment, imperfect lenses and those from the displays themselves. The images, if uncorrected, generally have luminance and color variations both between and within each projector channel. Finally, the images must be tiled in such as way as to have smooth transitions between each of the projector channels.
A multi-site videophone PBX system (1988)

This paper looks at the design of a multi-site PBX videophone system in terms of technology choices for transmission, switching and call-control, and considers the system in relation to future IPBX- and ISDN-based videophone systems.
