Supersonic flow over an axisymmetric backward-facing step (1990)

Large eddy numerical simulations of supersonic flows over an axisymmetric backward-facing step have been completed using a recently developed axisymmetric version of the finite element method-flux corrected transport algorithm, FEM-FCT. The code is based on the mixing layer and recompression premises of the Chapman-Korst model. It solves the time-accurate Euler equations utilizing 1) adaptive unstructured gridding to resolve flow feature details and 2) a conservative nonlinear scheme to capture features in the compressible flowfield. This approach may be employed since the location of the separation point is fixed at the sharp corner. The simulation allows the large-scale structures present in the mixing layer to interact dynamically with the recompression region. Comparisons have been made with available experimental data for a range of Mach numbers and step height to step radius ratios for which boundary-layer effects are not pronounced. In general, good agreement between predictions and measurements was found for 1) the time-averaged surface pressure distributions along the backstep and the reattachment wall, 2) the flowfield structure in general, and 3) the downstream reattachment lengths. Effects of axisymmetry were noted in flowfield characteristics such as increased base pressure, curvature of expansion fans, stronger recompression shocks, and higher Mach number levels in the subsonic recirculating region.
Activated, but not resting human Th2 cells, in contrast to Th1 and T regulatory cells, produce soluble ST2 and express low levels of ST2L at the cell surface (2002)

The T1/ST2 gene encodes, as a result of differential splicing, a cell surface protein (transmembrane form of T1/ST2, ST2L) and a soluble, secreted, protein (ST2). Here, we show that transcripts for both ST2L and ST2 are present in activated human Th2 clones, but not in Th1 and T regulatory clones. This activation-dependent expression of ST2L/ST2 transcripts was also found in short-term in vitro differentiated, activated CD4(+) Th2 cells. No expression of ST2L or ST2 mRNA was detected in any of the resting T cell subsets. Low cell surface expression of ST2L was detected on activated Th2 clones, and on freshly isolated non-IFN-gamma-producing CD4(+) peripheral blood T cells, activated with anti-CD3 and anti-CD28 mAb. Finally, ST2 could be detected in the culture supernatants of activated, but not resting, Th2 clones. Taken together, these results show that the T1/ST2 gene products are inducible proteins and that human Th2 cells, in addition to expressing ST2L at their cell surface, secrete ST2 following activation.
Vibrational relaxation rates in N2/CO2 mixtures as determined from low-frequency sound absorption measurements (1980)

Zuckerwar and Griffin [J. Acoust. Soc. Am. 68, 218–226 (1980)] have recently used a resonance tube to extend measurements of sound absorption in N2/CO2 mixtures to much lower frequency to pressure ratios (f/p) than previously obtained. Their results, when compared with previous measurements at higher CO2 concentrations, confirm that the nitrogen relaxes by a series process involving two v–v and one v–t exchange. A value of 7.5×10+4±10% s−1 atm−1 for the rate of the reaction CO2(00 °1)+N2?CO2(0310)+N2+416 cm−1 is obtained.
Non-scanning three-dimensional imaging using spectral interferometry with chirped frequency comb (2016)

One-shot 3D imaging-method with a chirped frequency comb was demonstrated using 2D pulse-to-pulse spectral interferometry. A step-height was measured with 6.1-μm-uncertainty, currently limited by the detection system. The method has large dynamic-range with high precision.

Flaw recognition in presence of interferences from fasteners and subsurface structures (2002)

The objectives of this paper are to detect and identify flaws in conducting tubes surrounded partially by subsurface structures. Signals from eddy current sensors are frequently contaminated by noise due to the presence of such elements. When employing single frequency systems it is very difficult to discriminate between various factors, which cause signal changes. To deal with this problem, application of the multi-frequency system and restoration procedure is proposed. Numerical simulations and experiments with various interfering structures were performed.
Self Q switching of a CW mode-locked Nd:YLF laser by cavity length detuning (1993)

The cavity length of a CW mode-locked Nd:YLF laser is detuned to investigate the effect of detuning on the output of the laser. Negative detunings of 0.4 to 2.4 mu m result in periodic modulations of the pulse envelope. Further negative detunings of 2.4 to 3.4 mu m produce undamped regular spikings, that is, stable self-Q-switching behavior with mode-locked pulses of 30 approximately 47 ps pulsewidths, which are as short as those of plain mode locking without Q switching. Similar self-Q-switching behavior is also produced by positive detunings, but the stability is very poor.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Morphological and biophysical identification of fibrous proteins in the amniote epidermis (1970)

Abstract Epidermal material from a variety of reptilian species, avian and mammalian scales have been examined by standard histological and x‐ray diffraction techniques. It has been found that morphologic and/or tinctorial properties are not good criteria for the identification of specific fibrous protein types. The distribution of fibrous protein types in reptilian epidermal material is very variable, especially in turtles. Lepidosaurian reptiles (the tuatara, snakes and lizards) are unique in showing an alternating vertical distribution of feather and α‐type proteins over the entire body surface. The protein distribution in crocodilian scales resembles exactly that found on avian scales. Mammals only possess the α‐type protein whatever the nature of the epidermal structure of modification.
Soft Information Aided ML Joint Frame Synchronization and Channel Estimation for Downlink MC-CDMA in the Presence of Narrowband Interference (2007)

Spectrum-overlay scenarios for wideband multi-carrier (MC) systems bring new technical challenges that must be considered during the system design. In such a scenario, the receiver has to perform actions, such as channel estimation and synchronization, in the presence of possibly strong in-band interference. In this paper, we modify the iterative maximum likelihood joint frame synchronization and channel estimation algorithm for downlink MC-CDMA presented in (M. Guenach et al., 2006) to have better performance in the presence of narrowband interference. The performance of the modified algorithm is verified through computer simulations and compared with the original one.
Uncertainty Approach to Subirrigation Design (1987)

The first and second order method of analyzing uncertainty is incorporated into the design of subirrigation systems. The uncertainty in the design due to both the unsaturated and saturated hydraulic conductivity is considered. Numerical examples are given that show how the method may enable designers of subirrigation systems to estimate confidence limits on the design drain spacing.
Eribulin in advanced urothelial cancer (AUC) patients (pts): A California Cancer Consortium trial—NCI/CTEP 7435. (2015)

4504 Background: There is an unmet need for new agents in AUC. We previously reported that eribulin, a microtubule modulator derived from black Pacific sea sponge toxin, is highly active against metastatic UC in frontline and previously treated settings (ASCO 2010; ECC 2013). Here we report composite results of 150 AUC pts treated in a single phase II trial. Methods: Eligible pts with AUC, calculated CrCl ≥ 20mL/min were treated in 3 cohorts of first line, 2nd line with or without tubulin exposure. Eribulin 1.4mg/m2 IV on d1 & 8, q3 wks. In each cohort RR > 20% considered promising; 41 pts in a Simon 2-stage design. PFS & OS were secondary endpoints. Results: Pt characteristics: Median age 68 yrs (range: 25-90); Males: 71%; KPS ≥ 90%: 57%; Transitional cell histology: 90%; Lower tract 88%, Visceral mets 67%, Bajorin risk groups: 0: 30%, 1: 61%, 2: 9%. Bajorin risk group, visceral mets +/- KPS associated with OS & PFS (p < 0.01) while renal fn, age, line of therapy & prior tubulin exposure did not. Toxicities included Gr3/4 neutropenia: 57%, FN: 4%, Gr3 Hb: 13%, Gr1/2 sensory neuropathy: 45%. Age > 70 associated with Gr3+ neutropenia, no factors including tubulin exposure predicted neuropathy, developing any Gr3+ toxicity associated with age > 70 & KPS. Conclusions: Eribulin exceeded the prespecified benchmark in all strata with highly encouraging single agent activity in AUC. Phase III evaluation of eribulin in AUC is warranted. (NCT00365157; UM1 CA186717; U01 CA062505; P30 CA014089; P30 CA033572). Clinical trial information: NCT00365157.Endpoint summary.

The functioning of the veterinarian in the Belgian pig sector: a questionnaire survey of pig practitioners. (2010)

The aim of the study was to gather information on the functioning of the pig practitioners in the current pig sector in Belgium by means of a questionnaire. It consisted of 76 questions dealing with the studies of veterinary medicine, the situation of the practitioners and the veterinary herd health guidance. Forty-three practitioners completed the questionnaire. On average, the respondents have 17 years of professional experience. Most of the veterinarians prefer that the current education system with the different main subjects in the last year of veterinary medicine studies is maintained, a minority prefers to have more (19%) or less (36%) differentiation during the study. Of all veterinarians who obtained their DVM degrees after 1997, 19 out of 20 have followed one or more courses related to pig medicine. Fifty-eight percent work as an independent practitioner and 42% as a practitioner associated with a feeding company. Forty-four percent work in a one-man practice and 56% in a group practice. Almost all veterinarians have a full-time job and work on average 54 hours per week. The respondents report to be the statutory herd veterinarian of 43 pig herds on average. A solid professional knowledge combined with good social skills to communicate with the farmer are considered to be the most important factors for a successful herd health guidance. An important part of the income (43%) is obtained by selling veterinary drugs. Eighty-five percent of the practitioners report that pig producers are not willing to pay for professional advice. The health status of the pigs in the herds is best monitored by performing necropsies and by a diagnostic work-up of a representative number of pigs of the herd, rather than by investigating pigs in the slaughterhouse. The majority of veterinarians think that several aspects related to the practice situation as well as the herd health guidance can be improved (administration, payment, importance of quality assurance labels for practitioners, medication, prescription of drugs). Eighty six percent of the respondents prefer to continue with their current jobs. This is an indication of professional satisfaction and illustrates that the current practitioners are positive and hopeful about their future in the pig production.
Single-Molecule Analysis of Chemotactic Signaling in <i>Dictyostelium</i> Cells (2001)

Single-molecule imaging techniques were used to reveal the binding of individual cyclic adenosine 3',5'-monophosphate molecules to heterotrimeric guanine nucleotide-binding protein coupled receptors on the surface of living Dictyostelium discoideum cells. The binding sites were uniformly distributed and diffused rapidly in the plane of the membrane. The probabilities of individual association and dissociation events were greater for receptors at the anterior end of the cell. Agonist-induced receptor phosphorylation had little effect on any of the monitored properties, whereas G protein coupling influenced the binding kinetics. These observations illustrate the dynamic properties of receptors involved in gradient sensing and suggest that these may be polarized in chemotactic cells.
A smart sonar object recognition system for robots (1993)

The authors describe an acoustic object identification system for use on industrial robots. The object recognition is based on comparing an object's acoustic fingerprint with those of known objects. Particular aspects discussed are how to distinguish the different objects which have the same area of reflection and how to decrease the position sensitivity. The system uses three piezoelectric transducers. The centre one acts as a receiver and the other two as transmitters, aligned symmetrically on both sides of the receiver. Some data processing methods are introduced to improve the recognition ability for similarly shaped objects.

On the Nanofiltration of Asphaltene Solutions, Crude Oils, and Emulsions (2010)

It has long been established that crude oils contain a colloidal suspension of asphaltenes where the mass fraction can range from 0 to 15%. The size of the colloidal particles is less well understood. Crude oil properties depend critically on the asphaltene content, yet measurement of these properties can be hindered by emulsified water and inorganic particulates in heavier crude oils. Here we explore the ability to isolate pure and unaltered crude oil samples using Gore-Tex membranes with nominal pore sizes as small as 30 nm where a transmembrane differential pressure no greater than 60 psi is employed. We first demonstrate that conventional crude oils can pass through a Gore-Tex membrane without alteration of their asphaltene content or their transport properties. Second, we demonstrate that the same filtration process can be used to extract crude oil from a water-in-oil emulsion where the extracted crude’s properties are not distinguishable from those of the original crude. Third, we show that these experiments put an upper bound on the asphaltene nanoaggregate size in crude oils. For all experiments, visible−near infrared (VIS−NIR) spectroscopy and Karl Fischer titration analysis are used to determine the potential loss of asphaltenes upon filtration and the effectiveness of the removal of water from emulsions. In all cases, negligible asphaltene loss was detected, indicating that asphaltene nanoaggregates and nanoaggregate clusters are smaller than the 30 nm nominal pore size of the membranes used here. While only small sample volumes were used, membrane separation of pure crude oil is an excellent method for isolating pure, representative crude oil samples.
Mechanisms of Abdominal Organ Injury in Seat Belt-Restrained Children (2007)

This evaluation of crashes in which belted children did and did not sustain abdominal injuries revealed key characteristics about their mechanism. In this data set, belt compression directly on the abdomen, manifested by improper initial placement of the seat belt, poor child posture, or misuse of the shoulder belt, resulted in abdominal injury in low-severity crashes in which other occupants sustained little injury. The cases pointed to control of torso excursion by consistent use of the shoulder belt and suggested that technologies such as lap belt pretensioners or belt-positioning booster seats might be a possible strategy, among others, for prevention.
Salivary immunoglobulins in recipients of bone marrow grafts. I. A longitudinal follow-up. (1994)

Patients receiving bone marrow transplantation (BMT) are prone to a variety of bacterial, viral and fungal infections in their oral cavity. We have therefore followed alterations in salivary Ig levels associated with BMT. Most of the patients were transplanted with allogeneic, MHC-matched BM after T cells were depleted by ex vivo treatment with an anti-lymphocytic monoclonal antibody (Campath-1) and autologous complement. Parotid saliva was collected at various time intervals before and after BMT, and IgM, IgG and IgA concentrations were determined by an enzyme linked immunosorbent assay (ELISA). A gradual fall in Ig levels was detected following patient's conditioning with a combination of chemo- and radiation therapy beginning 10 days prior to BMT. A rise in the titer of salivary Ig could be detected as early as 4 days post-BMT, which increased continuously and reached plateau levels within 2-3 weeks. However, about 3 weeks later the Ig titers decreased again and persisted at low levels for variable periods of time. A second increase in salivary Ig was detected approximately 2 months post-BMT, which persisted for prolonged periods of time. These results suggest that Ig secreted by donor B-lymphocytes and plasma cells passively transferred with the BM can rapidly reconstitute the salivary IgM, IgG and IgA of the immunocompromised recipient. However, when these cells cease to produce Ig the patients are still immunoincompetent and therefore enter a second phase of salivary Ig deficiency which may render them highly susceptible to opportunistic oral infections.(ABSTRACT TRUNCATED AT 250 WORDS)
