Experimental investigation of noise sources in cross-flow fans (1999)

Cross-flow fans are unusual types of blowers which operate in a fundamentally different way from axial or centrifugal fans. The flow enters and leaves the impeller in a direction vertical to its axis and passes the blade row twice, first radially inward and then radially outward. Hence, cross-flow fans are basically two-stage fans. Aerodynamic and acoustic modeling of cross-flow fans is extremely difficult because of the complexity of the flow field in the rotating impeller channels with a reversal of the flow direction during each revolution and large regions of severe flow separations. To obtain experimental input data for modeling efforts, experiments were performed with a scaled up model fan. The fan was installed in an open-inlet/ducted outlet test rig. Measurements were made of the unsteady pressures on the impeller blades and on the fan casing, in particular the vortex wall. The flow fields inside the impeller and at its outer periphery were studied by using hot wire anemometry and a three-hole probe. The effect of different casing geometries was examined. A simple model for broadband noise radiation involving surface dipole sources as suggested in an early paper by Sharland [JSV 1, 302–322 (1964)] predicts the spectrum measured in an anechoically terminated outlet duct reasonably well for Now with Behr GmbH &amp; Co., Mauserstrasse 3, 70469 Stuttgart, Germany
Electro-optic Sensor Of Thz Imaging And Spectroscopy (1997)

During the last several years time-domain THz spectroscopy has been applied on far-infrared characterization in many frontier research fields. We discuss the advantages and limitations of using free-space electro-optic sampling for the coherent detection of 2D spatially distributed phase and amplitude information of freely propagating terahertz beams with subpicosecond temporal resolution.
Expression of insulin-like growth factor I, its binding proteins, and its receptor in ovarian cancer. (1991)

Insulin-like growth factor (IGF) I is a polypeptide hormone important in normal growth and development. Although IGF-I is a mitogen for many cancer cell lines, previous work has suggested that autocrine production of IGF-I is uncommon in cancers of epithelial origin. In this study, expression of IGF-I, its binding proteins, and its receptor were examined in ovarian cancer cell lines and tissues. Of 10 ovarian cancer cell lines, 3 (OVCAR-3, OVCAR-7, and PEO4) expressed IGF-I mRNA. RNase protection assays using probes derived from IGF-IA, IGF-IB, and alternate exon 1 IGF-I complementary DNAs demonstrated that these cells contained a predominant IGF-I transcript with an alternate first exon. RNA extracted from primary and metastatic ovarian cancer tissues also expressed IGF-I mRNAs (7 of 7) with the alternate first exon. IGF-I protein was detected in OVCAR-3-conditioned media; this activity was secreted in conjunction with several IGF-binding proteins (IGFBPs). IGFBP-2, IGFBP-3, an Mr 24,000 species, and an Mr 30,000 species could also be demonstrated in OVCAR-3. Type I IGF receptor mRNA was found in all 10 of the ovarian cancer cell lines and all 7 of the primary or metastatic ovarian cancer tissues. IGF-I was a mitogen for OVCAR-3, demonstrating the presence of a functional type I IGF receptor. These data show that all the necessary components for an IGF-I-mediated autocrine loop are expressed by ovarian cancer cells.
A bifunctional reflector based on the chiral metasurface (2020)

Metasurfaces have attracted considerable attention due to their powerful abilities in electromagnetic wave manipulation and their easy fabrication. However, metasurface for circularly polarized waves with spin selective absorption characteristics has been less discussed. In this paper, an asymmetric chiral resonator lacking the mirror symmetry plane is studied, which presents different reflection properties for left-handed circularly polarized (LHCP) and right-handed circularly polarized (RHCP) waves. According to the theory of Pancharatnam-Berry (PB) phase, a bifunctional reflector based on the chiral unit is designed, which converts incident RHCP waves into vortex waves without changing handedness, while it absorbs incident LHCP waves. Full wave simulations are performed to validate the bifunctional performances of the metasurface. Such chiral metasurface paves the way to spin selective modulation of wavefronts, and present broad application prospects in the field of planar electromagnetic devices and communications.
The association between ethnicity and vaginal microbiota composition in Amsterdam, the Netherlands (2017)

The overall prevalence of having a VMB not dominated by lactobacilli in this population-based cohort of women aged 18-34 years in Amsterdam was high (38.5%), and women of sub-Saharan African descent were significantly more likely to have a polybacterial G. vaginalis-containing VMB than Dutch women independent of modifiable behaviors.
Microemulsions and Liquid Crystals (1986)

Abstract Microemulsions are dispersions of two unmiscible liquids made with surfactant molecules. Most of the time one of these liquids is water although non aqueous microemulsions can be made with polar liquids. Water can eventually contain dissolved salts. The other liquid is of apolar character and is generally called “oil,” even when dealing with organic solvents like benzene.
Exchange Rate Based Stabilization Policy in Latin America (2019)

Successful exchange rate based stabilization programs in Europe, Israel and elsewhere have led many economists and policymakers to advocate the use of pegged exchange rates as an integral part of stabilization programs in the emerging market economies. This chapter discusses the ambiguous concept of &quot;success&quot; in stabilization. It examines the role of the exchange rate regime and other policies in stabilization programs in Argentina, Bolivia, Brazil, Chile, Ecuador, Mexico, Peru and Uruguay. Even allowing for considerable ambiguity in classifications, both of stabilization success and of exchange rate regimes, the Latin American experience amply demonstrates that use of the exchange rate as a nominal anchor is neither a necessary nor a sufficient condition for successful stabilization policy. The Latin American experience shows that fixed exchange rates are more likely to give way in the face of continued inflation than for inflation to be constrained by a fixed rate.

Smooth generation of 3H-2-benzopyran-3-ones and their Diels–Alder reactions with olefinic dienophiles (1991)

The generation of methoxy-substituted 3H-2-benzopyran-3-ones from o-acylphenylacetic acid derivatives in acetic anhydride at 140 °C and their in situ Diets–Alder reactions being inefficient in the synthesis of some carbocyclic compounds, alternative reagents have been used. It is shown that, e.g. 1,3-dicyclohexylcarbodiimide (DCC) with 2-hydroxypyridine, disuccinimidyl carbonate (DSC), 2-ethoxy-N-ethoxycarbonyl-1,2-dihydroquinoline (EEDQ) of 2-isobutoxy-N-isobutoxycarbonyl-1,2-dihydroquinoline (IIDQ) are much more efficient reagents.Using these alternative reagents the formation of side-products from the benzopyranone, e.g. chrysene, can be avoided; with the modified DCC-method the 6,7-dimethoxy-1 -methyl-2-benzopyran3-one intermediate 8a can be identified spectroscopically. An exemplified procedure with IIDQ is proposed, opening new prespectives for Diets–Alder reactions of unstable or less reactive dienophiles with problematic benzopyranones.
A Novel Local Motion Planning Framework for Autonomous Vehicles Based on Resistance Network and Model Predictive Control (2019)

This paper presents a novel local motion planning framework in a hierarchical manner for autonomous vehicles to follow a trajectory and agilely avoid obstacles. In the upper layer, a new path-planning method based on the resistance network is applied to plan behaviors (e.g. lane keeping or changing), where the human-like factors can be included to simulate different driver styles, such as the aggressive, moderate, and conservative. The planned results (i.e. the lane-change command and the local planned path) will guide the lower-layer planner to decide the local motion. In the lower layer, for the sake of simplicity and alleviation of the computational burden, two separate model predictive controllers (MPC) based on a point-mass kinematic model are utilized for both longitudinal and lateral motion planning. Finally, a super-twisting sliding mode controller (STSMC) based motion tracker is designed to show the feasibility of the proposed decoupled planning method and decide the desired control actions of autonomous vehicles. Several scenarios are defined to comprehensively test and demonstrate the effectiveness and the real-time applicability of the new motion-planning framework. The results show that the proposed method performs very well in the planning and tracking process and takes less than 25 ms for the whole planning process, which can be easily implemented in real-world applications.
Characterization of oxide barrier layers prepared by atomic layer deposition (2017)

Atomic layer deposition has become an important thin-film growth technique for producing gas diffusion barriers because of its low process temperature and its ability to produce uniform films. In this work, atomic layer deposition was used to deposit various Al 2 O 3 and ZnO thin films on polyethylene terephthalate substrates; subsequently, the physical properties and water vapor transmission rates of the films were characterized. Single and hybrid films (Al 2 O 3 , ZnO, Al 2 O 3 /ZnO, and ZnO/Al 2 O 3 ) with thicknesses of 25, 50, and 100 nm at a deposition temperature of 60°C were investigated. The deposited films were characterized for surface roughness, optical transmittance, adhesion, water vapor transmission rate, and contact angle. The results showed that the double-layer structure provided a higher water vapor transmission rate and higher adhesion strength than those of the single-layer structure although both the surface roughness and optical transmittance of the single-layer structure were slightly better than those of the double-layer structure. The results revealed that the atomic layer deposition-grown hybrids could act as water vapor barriers.
Effects of Advances in Analog, Mixed Signal and IO Circuits on Test Strategies (2008)

This paper focuses on high level integration of analog on today's products. We will present the paradigm change required to test these circuit from ATE driven solutions to DFT/BIST/BOST techniques. We will present industrial examples of implementation and silicon results. The examples will range from PLL Testing using ATE approaches and on-chip jitter measurements (TDC based approach) to ADC testing using on chip ramp generation and off chip active TIU (Test Interface Unit) approach to PCIe testing using capable tester to DFT based methods. The talk will focus on what techniques performed well and provided a good alternative solution and which ones resulted in more yield loss or high DPM escapes.
Dental Casting Alloys and Cadmium Poisoning (1973)

カドミウムによる中毒の起こり方を調査し, 歯科用合金中に含まれるカドミウムの量に対比しつつ, それによる為害作用の可能性を検討した。カドミウムは, 微量でも長期にわたって反復吸収されると蓄積されて慢性中毒を起こすことがある。しかし口内に装用される修復物の合金から溶出するカドミウムはきわめて微量であって, これによって患者に為害作用を及ぼす可能性はない。ところが, 鋳造時の加熱は相当量のカドミウムを揮散させるので, 換気の悪い技工室での鋳造作業が術者に為害作用を及ぼす可能性は否定できない。
Integration of GPS and Loran-C (1996)

F 1945 through the 1970s, the Long Range Navigation System (Loran-C) was developed by the United States and the Soviet Union (the Soviet system is called Chayka) primarily for military use. In the 1970s, LoranC was declared an official national system by the United States and Canada. These decisions spurred a wealth of civilian applications and tremendous commercial development. The integrated circuit and microprocessor improved the performance of Loran-C receivers, while greatly reducing their size and price. Solidstate Loran transmitters were introduced, and these had much greater reliability and efficiency than their vacuum tube predecessors. Today, Loran provides service to nearly a million maritime, airborne, and terrestrial users throughout most of the northern hemisphere. The coverage of Loran is shown in Fig. 1, where the coverage contours are for the extremely reliable groundwave coverage. Skywave propagation does provide extended coverage, but it is not as reliable. Recently, the United States has added four new Loran transmitters to cover the middle of the United States (to fill the midcontinent gap)With these new transmitters, five or more Loran signals are available 95% of the time over more than 95% of the conterminous United States (CONUS). Furthermore, the Far East Loran Technical Group, which includes Japan, the Peoples Republic of China, Korea, and the Commonwealth of Independent States, has agreed to build and operate six Loran chains under the auspices of the International Association of Lighthouse Authorities. As part of this effort, Japan and Korea have already contracted to build three solid-state Loran transmitters to replace older tube-type transmitters.
Subjectivity in personal storytelling with visualization (2017)

In this article we explore visualization for personal storytelling and investigate techniques for communicating subjective experiences in personal visual narratives. Personal stories are often subjective and storytellers omit, make up, or embellish details to craft engaging stories or to communicate a perspective. As growing personal data collections allow individuals to leverage visualizations, we explore how personal visual narratives can express subjectivity. From an analysis of personal visualizations created by data enthusiasts, designers and artists, we collect techniques for deliberately expressing subjectivity during data collection, processing, visual encoding, and presentation. Our results prompt a discussion about the role and potential of subjectivity in personal visual storytelling.

Managing Lymphoma with Non-FDG Radiotracers: Current Clinical and Preclinical Applications (2013)

Nuclear medicine imaging modalities such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT) have played a prominent role in lymphoma management. PET with [(18)F]Fluoro-2-deoxy-D-glucose (FDG) is the most commonly used tool for lymphoma imaging. However, FDG-PET has several limitations that give the false positive or false negative diagnosis of lymphoma. Therefore, development of new radiotracers with higher sensitivity, specificity, and different uptake mechanism is in great demand in the management of lymphoma. This paper reviews non-FDG radiopharmaceuticals that have been applied for PET and SPECT imaging in patients with different types of lymphoma, with attention to diagnosis, staging, therapy response assessment, and surveillance for disease relapse. In addition, we introduce three radiolabeled anti-CD20 antibodies for radioimmunotherapy, which is another important arm for lymphoma treatment and management. Finally, the relatively promising radiotracers that are currently under preclinical development are also discussed in this paper.
Spherical crystallization of glipizide for improvement of micrometric properties (2010)

Glipizide is an anti diabetic drug with water insolubility and poor compressibility. Glipizide pure drug was converted into spherical crystal agglomerates via the spherical crystallization technique using dichloromethane water-chloroform solvent system. The various parameters optimized were type, amount and mode of addition of bridging liquid, temperature and agitation speed to get maximum amount of spherical crystals. These were characterized for micromeritic properties (particle size and shape, flow ability), pack ability (bulk density), wet ability (contact angle) and compressibility. It was revealed from the study that spherical agglomerates exhibited improved flow ability, wet ability and compaction behavior.

Altered Guanylyl-Cyclase Activity In Vitro of Pulmonary Arteries from Fetal Lambs with Congenital Diaphragmatic Hernia (2002)

Nitric oxide (NO) plays a major role in the modulation of perinatal pulmonary vascular tone. Congenital diaphragmatic hernia (CDH), a major cause of severe persistent pulmonary hypertension of the newborn (PPHN), is often refractory to inhaled NO. Alterations in NO/cyclic guanosine 3',5' monophosphate (cGMP)-mediated pulmonary vasodilatation may contribute to PPHN in CDH. We assessed NO/cGMP-mediated pulmonary vasorelaxation in vitro in 140-d gestational lamb fetuses with surgically created left CDH (term = 147 d) to age-matched controls. Relaxation of fourth generation intralobar pulmonary artery rings in response to the endothelium-dependent vasodilator, acetylcholine (ACh), and to the specific inhibitor of cGMP-phosphodiesterase (PDE), zaprinast, did not differ between the two groups. By contrast, relaxation in response to the calcium ionophore A23187 was impaired in CDH as compared with control animals. Relaxation in response to the NO donor sodium nitroprusside (SNP) (a direct activator of soluble guanylyl cyclase [sGC]) was also impaired in CDH animals as compared with controls. Repeating the challenge increased vasorelaxation in response to SNP in CDH as compared with control animals. Immunohistochemistry revealed the presence of endothelial NO-synthase in the endothelium of pulmonary arteries from both control and CDH animals. We conclude that endothelium-dependent vasodilatation in response to ACh and A23187 was differently affected in the fetal surgical CDH-lamb model. Furthermore, activity of sGC but not that of PDE was impaired in CDH animals. PPHN and decreased inhaled NO responsiveness in CDH may involve decreased sGC activity.
Microoptic double beam system for reflectance and absorption measurements at high pressure (1982)

A microoptical double beam system for reflectance and absorption measurements from small samples (less than 100 μm size) in the spectral range of 0.5–5 eV is described. In conjunction with a diamond anvil high-pressure cell the system is particularly useful for optical reflectivity measurements at pressures up to 400 kbar. Examples are furnished illustrating the use of the system in high-pressure investigations of the stage two graphite intercalation compound C24SbCl5 and of solid oxygen. We briefly comment on Raman spectroscopy at high pressure.

Le sac endolymphatique : ses fonctions au sein de l’oreille interne (2004)

The endolymphatic sac is a non-sensory organ of the inner ear. It is connected to the endolymphatic compartment that is filled with endolymph, a potassium-rich fluid that bathes the apical side of inner ear sensory cells. The main functions ascribed to the endolymphatic sac are the regulation of the volume and pressure of endolymph, the immune response of the inner ear, and the elimination of endolymphatic waste products by phagocytosis. Functional alteration of these functions, leading to deficient endolymph homeostasis and/or altered inner ear immune response, may participate to the pathophysiology of Ménière's disease, an inner ear pathology that causes episodes of vertigo, sensorineural hearing loss and tinnitus, and is characterized by an increase in volume of the cochleo-vestibular endolymph (endolymphatic hydrops).
Evaluation of the efficacy of lambda-cyhalothrin applied by three spray application methods for emergency control of Aedes aegypti in Costa Rica. (2003)

An extended duration formulation of lambda-cyhalothrin (Icon CS) applied as either an ultra-low volume (ULV) or thermal fog spray from a new hand-held sprayer (Twin-Fog) or as a low-volume spray (LV) from a backpack mist blower against Aedes aegypti was evaluated in Costa Rica. Spray applications were made at the front door for 1 min or to each room for 15 sec for the ULV and LV, and thermal fog applications were made to houses in separate blocks for each treatment. The efficacy and duration of effectiveness of the spray was determined from sentinel caged mosquito mortality and mosquito collections from within houses using hand-held, battery-powered aspirators. Sentinel caged mosquito mortality in both open and sequestered locations was 97-100% for the ULV and thermal fog spray treatments, with control mortality less than 2%. Both ULV applications (front door and each room) provided 3 wk of significant control (P < 0.05) based on adult Ae. aegypti house collections.
