Miniaturized spurious passband suppression microstrip filter using meandered parallel coupled lines (2005)

A novel meandered parallel coupled-line structure is proposed to suppress the first spurious passband of a microstrip bandpass filter. The meandered parallel coupled line can equalize the modal transmission phases at any interested frequency such as first spurious passband frequency due to its dispersive response. Several filters are designed and fabricated on a substrate with a dielectric constant of 10.2 and a thickness of 50 mil (1.27 mm) to demonstrate the validity of the proposed method. The example filters are chosen to be of large fractional bandwidth and with a relatively high dielectric-constant substrate where, in these cases, the first spurious passband near twice of the passband frequency (2f/sub o/) seriously degrades the conventional parallel coupled filter's upper stopband performance. The upper stopband performance of the proposed filters drastically improves that the measured first spurious passband are suppressed to better than -50 dB for all example filters. Besides, a meandered coupled line not only suppresses the filter's first passband, but also largely shrinks its length. The characteristics of the proposed structure and the design procedures of the filter are described in detail.
The Use of 23.4% Hypertonic Saline for the Management of Elevated Intracranial Pressure in Patients With Severe Traumatic Brain Injury: A Pilot Study (2009)

Based on this retrospective analysis, 23.4% HTS is more efficacious than mannitol in reducing ICP. If these results are confirmed in a prospective, randomized study, 23.4% HTS may become the agent of choice for the management of elevated ICP after TBI.
Designing enterprise-oriented network management applications (2002)

The success of integrated network and systems management solutions depends on the integration of business processes with network and systems management. The increasing distribution of management resources (including people) necessitates groupware/workflow-integrated enterprise-wide solutions for network management. The design of network management systems involves the cooperation of multiple groups of people within and across organisations. Hence it may be useful to adopt a formal design methodology. However, such a methodology needs to be flexible enough to accommodate a wide variety of design models and notations in this multidisciplinary area of research. This paper presents a new methodology (called CoMEN-cooperative management methodology for enterprise networks) for the design and implementation of enterprise-oriented network management solutions.
A clustering approach for radar warning receivers (2015)

In this study a mission data base based clustering approach that can be used in radar warning receivers for the purpose of deinterleaving is suggested. Cell based deinterleaving technique, which is widely used at the present time, utilizes the information of direction of arrival, frequency and pulse width. In this study, different from this approach used in the literature, frequency, direction of arrival and pulse amplitude parameters are utilized for deinterleaving. With this technique it is shown that accurate results can be obtained by simulation.
<i>RRM1</i> Modulated In Vitro and In Vivo Efficacy of Gemcitabine and Platinum in Non–Small-Cell Lung Cancer (2006)

The results strongly suggest that tumoral RRM1 expression is a major predictor of disease response to gemcitabine/platinum chemotherapy. ERCC1 expression is predictive of response albeit to a lesser degree.
TGF-β/Smad3 Signaling Regulates Brown Adipocyte Induction in White Adipose Tissue (2012)

Recent identification of active brown fat reserves in adult humans has re-stimulated interest in the role of brown adipocytes in energy homeostasis. In addition, there is accumulating evidence to support the concept of an alteration in energy balance through acquisition of brown fat features in traditional white fat depots. We recently described an important role played by the TGF-β/Smad3 signaling pathway in modulating the appearance of brown adipocytes in traditional white fat, and its implications to thermogenesis, mitochondrial energetics, energy expenditure, and protection from diabetes and obesity. Here we review the data supporting this phenomenon and put into perspective the promise of conversion of white fat to a brown fat state as a potential therapeutic option for obesity and diabetes.
Establishment of a human melanoma cell line lacking p53 expression and spontaneously metastasizing in nude mice. (1995)

Nine human melanoma cell lines established in our laboratory were analyzed for p53 gene expression and their tumorigenic and metastatic potential in nude mice. Northern blot analyses showed that five of the cell lines (55%) had either complete loss or low levels of p53 transcripts. Immunocytochemical analysis for p53 protein expression agreed with mRNA analysis results. Nucleotide sequencing showed no mutations in exons 5 through 8 of the gene. All cell lines except one gave rise to tumors at subcutaneous inoculation sites in nude mice. The melanoma cell line UISO-MEL-6, completely lacking p53 expression, spontaneously metastasized to lung and liver in nude mice.
Hybrid nanogels by encapsulation of lanthanide-doped LaF3 nanoparticles as elemental tags for detection by atomic mass spectrometry (2010)

In this article we demonstrate that hybrid nanogels can be prepared by encapsulation of reactive nanoparticles (NPs) directly during nanogel synthesis. Nanogels investigated in present study consist of poly(N-vinylcaprolactam-co-(2-acetoacetoxyethyl) methacrylate) copolymer. The modification of the LaF3:Eu nanoparticle surface with reactive double bonds allows effective incorporation of the NPs into the nanogel structure. This approach ensures effective encapsulation of varying amounts of NPs into the nanogel interior with a loading efficiency close to 95%. The NPs are covalently bound to the nanogel core, and no NP leakage occurs. Reactive NPs act as multifunctional cross-linking agents and increase the cross-linking degree of the nanogels. We demonstrate the possibility of the incorporation of LaF3 nanoparticles doped with different ions (Eu, Tb, Pr, Gd) or nanoparticle mixtures into nanogels. These nanogels exhibit temperature-sensitive properties and superior colloidal stability in water and other aqueous media.
Key issues in secure, error resilient compressive sensing of multimedia content (2009)

Multimedia applications have played an increasingly important role in entertainment, security, remote sensing, monitoring and other civil and military applications. The traditional approach to multimedia acquisition, communication and consumption chain starts with high resolution content acquisition, followed by content processing, image and video compression and then delivery over wireless and wired line networks. After decades of theory, technology and product developments, the traditional paradigm has approached the limits established by a number of physical barriers. In this talk, we review a few critical issues when applying compressive sensing theory to multimedia applications and propose, on a high level, some preliminary potential solutions.
Two methods for computing the imaging condition for common-shot prestack migration (1991)

Abstract This note addresses two methods of computing the imaging condition for prestack migration of common-shot seismic data; our work is based on the ideas from reverse-time migration for both poststack (Loewenthal and Mufti, 1983; McMechan, 1983) and prestack data (Chang and McMechan, 1986). In reverse-time migration of poststack data, the whole stacked section is backward-extrapolated in time, with half of the medium velocity to time zero. All exploding reflectors are imaged at once at time zero. The time zero is referred to as the imaging condition. In prestack migration, the imaging condition is more involved. Each spatial grid point (treated as a point diffractor) has a different excitation time, which is equal to the one-way traveltime from the source to that grid point. Each point diffractor is imaged separately at its excitation (the "imaging time").
Wine Grape (<i>Vitis vinifera</i>) Response to Fall Exposure of Simulated Drift from Selected Herbicides (1997)

‘Lemberger’ wine grape response to fall application of selected herbicides applied at simulated drift rates was studied in 1992 and 1993. Chlorsulfuron, thifensulfuron, 2,4-D, glyphosate, bromoxynil, and 2,4-D plus glyphosate were applied at 1/100, 1/33, 1/10, and 1/3 of a selected maximum rate for use in wheat or fallow. All herbicides, except bromoxynil and thifensufluron, caused symptoms on grapevines at the highest rate during the spring following fall application. The most severe symptoms were caused by 2,4-D and 2,4-D plus glyphosate, whereas the least symptoms were caused by chlorsulfuron and glyphosate. The severity of symptoms increased and shoot growth, leaf area, internode length, and dry cane weight decreased as the rates of 2,4-D and 2,4-D plus glyphosate increased. Chlorsulfuron and glyphosate reduced the growth of grapevines only when applied at the highest rate during the fall. The data show that exposure of wine grapes to 2,4-D or 2,4-D plus glyphosate during the fall can adversely affect the growth of grapevines the following spring.
Nonlinear mixed integer programming problems using genetic algorithm and penalty function (2002)

We propose a method for solving nonlinear mixed integer programming (NMIP) problems using genetic algorithms (GAs) and a penalty function method. The penalty function method was used to construct a fitness function to evaluate chromosomes generated from genetic reproduction. Therefore, the mean of satisfactory degrees of systems constraints were introduced. Also, we apply the method for solving optimization problems which belong to nonlinear programming or NMIP problems, using the proposed method. The performance of the proposed method was evaluated through numerical experiments to demonstrate the efficiency of the proposed method.
Preclinical and clinical studies of bone marrow uptake of fluorine-1-fluorodeoxyglucose with or without granulocyte colony-stimulating factor during chemotherapy. (1998)

Substantial increases in bone marrow FDG uptake are rapidly induced by CSF treatments and should not be misinterpreted as diffuse bone marrow metastases.
Development and Applications of a Fiber-Coupled Atom-Based Electric Field Probe (2018)

We are developing a fundamentally new atom-based approach for electric (E) field measurements. This new approach will lead to a self-calibrated, SI traceable, E-field measurement, providing us with the capability to perform measurements on a fine spatial resolution in both the far- and near-fields. Here, we discuss the development and applications of the first moveable fiber-coupled version of this atom-based E-field measurement approach. We show results for various measurements including: far-field measurements of the E-fields, measurements of the E-field distribution along the surface of a circuit board, field measurements in apertures, measurements of the directivity pattern of a horn antenna, and measurements made in a GTEM cell.
Characterization of Direct Immobilized Probe DNA on Partially Functionalized Diamond Solution-Gate Field-Effect Transistors (2006)

Amino groups were functionalized directly on the diamond surface after treating 0.5 monolayer of oxidation for detection of DNAs. Also, immobilization of probe DNAs was carried out directly on the partially aminated diamond without linker molecules. Specific hybridization with 21-mer DNA at a concentration of 100 nM could be clearly detected by two methods, fluorescence microscopy and diamond solution-gate field-effect transistors (SGFETs). DNA hybridization was confirmed using Cy-5-labeled target DNA on a micropatterned diamond surface. The changes in gate potential by the negative charge of immobilized or hybridized DNA were measured on SGFETs and hybridization efficiency on the functionalized diamond surface was estimated as about 40%.

Utilizing GaalAs Laser Diodes As A Source For Frequency Modulated Continuous Wave (FMCW) Coherent Laser Radars (1989)

This paper describes the development of a Coherent Laser Radar utilizing a Frequency Modulated (FM) GaAlAs laser diode as an optical source. Both metrology (low speed, high accuracy) and vision (high speed, low accuracy) systems have been developed. Characteristics of presently available laser diodes important to this application are discussed, including coherence length, modal and tuning properties, and the effect of back reflected light on the laser diode's performance. Techniques to overcome current laser limitations are presented. These include an electronic linewidth narrowing scheme to enhance the coherence length of the source laser and thus the ultimate range of the radar, and the use of tuning linearization electronics. Finally, the impact of future laser diode technology, such as electronically tunable lasers, is discussed with respect to this application.
Concordance of absolute and relative plasma volume changes and stability of <scp><i>F</i></scp><sub>cells</sub> in routine hemodialysis (2015)

Central hematocrit (H) measurements are currently used to track the degree of ultrafiltration-induced hemoconcentration with the aim to detect and prevent excessive intravascular fluid depletion during hemodialysis (HD). Failure to maintain hemodynamic stability is commonly attributed to the misinterpretation of H caused by an unaccountable increase in Fcells , the ratio of whole-body hematocrit to H. It was the aim to examine Fcells under everyday conditions in a group of stable HD patients. Absolute plasma volume (Vp ) and H were concomitantly measured during routine HD in the extracorporeal system in hourly intervals by noninvasive and continuous technology (CritLine-Instrument-III) and indocyanine green dye dilution to derive relative plasma volumes from Vp and H (RPVp , RPVH ), respectively, and to calculate Fcells . Thirteen patients were studied during two midweek treatments (n = 26). Both absolute Vp (P < 0.05) and relative plasma volumes RPVH (P < 0.001) decreased during HD. Vp at any time point was positively correlated to RPVH (r = 0.52). Moreover, relative plasma volumes RPVH and RPVp determined by independent techniques were identical and showed negligible bias (-0.2%) but considerable limits of agreement (-15.6% to +15.3%). Fcells was stable and in the range of 0.9 ± 0.05 throughout HD and not different from the value assumed at the beginning of HD. Although Fcells remains constant in patients on routine dialysis and relative plasma volumes (RPVH and RPVp ) determined by independent techniques are therefore comparable, the variability of experimental conditions during dialysis and the limited accuracy of absolute volume measurements using available technology continues to complicate the ultrafiltration control problem.
Insect contamination protection for laminar flow surfaces (1986)

The ability of modern aircraft surfaces to achieve laminar flow was well-accepted in recent years. Obtaining the maximum benefit of laminar flow for aircraft drag reduction requires maintaining minimum leading-edge contamination. Previously proposed insect contamination prevention methods have proved impractical due to cost, weight, or inconvenience. Past work has shown that insects will not adhere to water-wetted surfaces, but the large volumes of water required for protection rendered such a system impractical. The results of a flight experiment conducted by NASA to evaluate the performance of a porous leading-edge fluid discharge ice protection system operated as an insect contamination protections system are presented. In addition, these flights explored the environmental and atmospheric conditions most suitable for insect accumulation.
"From Exile to Zion" - Ethical Perspectives from the Twin Psalms 127 and 128 (2009)

In the past psalms were often read and interpreted as single texts. With the redactional-historical approach to psalm interpretation psalm texts are more regularly interpreted within the smaller collections where they are situated? The theological relationship between a single psalm and the larger collection becomes evident when such a text (or texts) is (are) read against the background of the collection's theological programme or intention. To illustrate this relationship the twin Psalms 127 and 128 are eclectically selected from the Sîrē Hama'alôt psalms (120-134) in Book V (107-150) of the Psalter. These wisdom-related-psalms are examined for their Torah ethical thinking as envisaged in Psalm 1. With the theological programme "From exile to Zion" of the Sîrē Hama'alôt collection (120-134) these twin psalms contribute to the ethical reflection of the Yahweh-faith in Book V.
Structure and function of the glycoprotein Ib-IX-V complex (1997)

Following injury to a blood vessel, platelets rapidly adhere to the site of exposed subendothelial matrix in the vessel wall, become activated, and secrete granule contents that will recruit and activate other platelets, which then aggregate at the site and seal the defect in the vessel wall. The clot that forms prevents further blood loss. This process can become deranged in diseased blood vessels, such as coronary arteries narrowed by atherosclerosis. Platelets will also adhere to these vessels when matrix components are exposed by plaque rupture, with potentially disastrous results. The platelet glycoprotein Ib-IX-V complex plays crucial roles in both of these processes by mediating platelet adhesion to sites of blood vessel injury and by participating in the thrombin induced aggregation of platelets. This adhesion receptor complex is unique in that it is the only one of its kind. In this review, we discuss recent developments in elucidating the structure, topography, and functions of this important receptor complex.
Synthesis and antibiotic activities of CRAMP, a cathelin-related antimicrobial peptide and its fragments (1999)

CRAMP, a 37-amino acid cationic antimicrobial peptide was recently deduced from the cDNA cloned from mouse femoral marrow RNA. In order to investigate the structure-activity relationship and functional region of CRAMP, CRAMP and its 18-mer overlapping peptides were synthesized by the solid phase method. CRAMP showed broad spectrum antibacterial activity against both Gram-positive and Gram-negative bacterial strains (MIC: 3.125- 6.25 μM) but had no hemolytic activity until 50 μM. CRAMP was found to have a potent anticancer activity (IC50: 12-23 μM) against two human small cell lung cancer cell lines. Furthermore, CRAMP was found to display faster bactericidal rate in B. subtilis rather than E. coli in the kinetics of bacterial killing. Among 18-meric overlapping fragment peptides, only CRAMP (16-33) displayed potent antibacterial activity (MIC: 12.5-50 μM) against several bacteria with no hemolytic activity. Circular dichroism (CD) spectra analysis indicated that CRAMP and its analogues will form the amphipathic α- helical conformation in the cell membranes similar to other antimicrobial peptides, such as cecropins and magainins.
Design of an SMA Actuated Mechanotransductive Implant for Correcting Short Bowel Syndrome (2010)

Short bowel syndrome is a serious medical condition afflicting an estimated 20,000 to 200,000 people in the United States with mortality rates as high as 40%, despite current treatments. Recent research on mechanotransduction, the process through which mechanical load induces tissue growth, has successfully demonstrated permanent growth of healthy, functional bowel in small animals. Unfortunately, the underlying technological approaches limit further research of growth under different load profiles and extension to safe clinical devices. This paper presents a fully implantable bowel extender which expands via a unique Shape Memory Alloy (SMA) driven ratcheting mechanism, measures the bowel tension and load, and enables studies of mechanotransductive bowel tissue growth where the displacement or load may be controlled wirelessly in real-time. The architecture and operation of the bowel extender is illustrated, focusing on the SMA driven ratcheting mechanism that incrementally expands the device. To help visualize the SMA wire and reset spring design, an alternative graphical method is outlined which transforms the SMA material curves into a Reset View based on predictions of the system forces. An analytical model predicts the ratchet mechanism force with tooth and pawl geometry selected based on packaging, load-bearing, and kinematic constraints. Force limits to maintain tissue health are established from ex vivo and in vivo porcine small bowel loading experiments. The Reset View methodology is applied to design a bowel extender prototype which is used to experimentally validate the ratchet force model. The functionality device is demonstrated, operating against loads much larger than specified, validating the device’s ability to enable new studies of mechanotransductive bowel growth in pigs.
British Airways ETOPS Flight Planning System (1993)

The constraints imposed by the regulatory authorities give flight crews more tasks to perform at the flight planning stage for an Extended Range Twin Operations (ETOPS) flight than for a non–ETOPS flight. Among the additional checks the flight crew has to make are the following: (i) That the aircraft will at all times be within the distance, calculated using the still–air single engine speed for the certified time, from the nearest ‘ suitable ’ airfield.(ii) That the ETOPS planning minima, which are typically three times the Category 1 operating minima in terms of forecast cloud base and visibility, are attained for each of the ‘suitable’ airfields used. (iii) That the weather at each of the ‘ suitable’ airfields used is forecast to be above the planning minima, not just for the time of passing, but for a period, termed the time window, from one hour before to one hour after the expected time of arrival of the aircraft at this airfield. (iv) That there is sufficient fuel, using the most critical fuel scenario, to take the aircraft from the critical point to any ‘ suitable’ airfield used in the calculation of the route.
Endoscope-Assisted Microsurgery for Treatment of a Suprasellar Craniopharyngioma Presenting Precocious Puberty (2001)

Being the most common childhood tumor to involve the hypothalamus and pituitary gland, craniopharyngioma, a histologically benign tumor, is usually related to growth retardation and hypogonadism. The presentation of precocious puberty is very rare for a hypothalamic craniopharyngioma. Here, we report such a case. The female patient had presented with symptoms of menarche and breast development since she was 6 years old. Hormonal therapy with a gonadotropin-releasing hormone analogue was instituted to cease precocious puberty but was unsuccessful. Magnetic resonance imaging of the sella showed a 1-cm tumor in the hypothalamic area. Through a pterional approach, the tumor was removed en bloc with endoscope-assisted microsurgery. After the operation, our patient's symptoms improved, so the hormone therapy was discontinued. This extremely unique association of craniopharyngioma and precocious puberty, the causes and mechanisms involved along with the advantages of endoscope-assisted microsurgery are discussed.
