Transcutaneous oxygen tension in subjects with tetraplegia with and without pressure ulcers: a preliminary report. (1999)

This study compared transcutaneous oxygen tension (TcpO2) in subjects with paraplegia and pressure ulcers (PU), those with paraplegia and no pressure ulcer (NPU), and ambulatory controls. TcpO2 was measured using a surface-electrode monitoring system, recorded at 1-min intervals for 5 min and averaged. Mean TcpO2 was significantly lower in the PU than the NPU and control groups (23.53+/-1.83 vs. 58.93+/-2.53 and 79.70+/-6.77 mmHg, respectively, p<0.05). In a PU subgroup (n=4) mean TcpO2 of the pressure ulcer and nonpressure ulcer sides (trochanter or ischium) were significantly different (21.05+/-2.98 vs. 67.65+/-2.11 mmHg, respectively, p<0.001). Additionally, the NPU group demonstrated significantly lower TcpO2 than the controls. PUs had a greater reduction in TcpO2 levels relative to controls than NPUs. No association was found between TcpO2 and duration of injury, completeness of lesion, or smoking history. Thus, TcpO2 may be an effective method to identify individuals who are susceptible to pressure ulcers. The further attenuation of TcpO2 observed in the PU group may be useful to help predict whether ulcers will heal with local care or will require additional treatment.
A Supervised Learning Approach for Dynamic Sampling (2016)

Sparse sampling schemes have the potential to reduce image acquisition time by reconstructing a desired image from a sparse subset of measured pixels. Moreover, dynamic sparse sampling methods have the greatest potential because each new pixel is selected based on information obtained from previous samples. However, existing dynamic sampling methods tend to be computationally expensive and therefore too slow for practical application. In this paper, we present a supervised learning based algorithm for dynamic sampling (SLADS) that uses machine-learning techniques to select the location of each new pixel measurement. SLADS is fast enough to be used in practical imaging applications because each new pixel location is selected using a simple regression algorithm. In addition, SLADS is accurate because the machine learning algorithm is trained using a total reduction in distortion metric which accounts for distortion in a neighborhood of the pixel being sampled. We present results on both computationally-generated synthetic data and experimentallycollected data that demonstrate substantial improvement relative to state-of-the-art static sampling methods.
Effects of heart valve prostheses on phase contrast flow measurements in Cardiovascular Magnetic Resonance – a phantom study (2016)

Characterization and Evaluation of Neuronal Trans-Differentiation with Electrophysiological Properties of Mesenchymal Stem Cells Isolated from Porcine Endometrium (2015)

Endometrial stromal cells (EMSCs) obtained from porcine uterus (n = 6) were positive for mesenchymal stem cell markers (CD29, CD44 and CD90), and negative for epithelial marker CD9 and hematopoietic markers CD34, CD45 analyzed by flow cytometry. Further the cells were positive for expression of mesenchymal markers, CD105, CD140b, and CD144 by PCR. Pluripotent markers OCT4, SOX2, and NANOG were positively expressed in EMSCs analyzed by Western blotting and PCR. Further, differentiation into adipocytes and osteocytes was confirmed by cytochemical staining and lineage specific gene expression by quantitative realtime-PCR. Adipocyte (FABP, LPL, AP2) and osteocyte specific genes (ON, BG, RUNX2) in differentiated EMSCs showed significant (p < 0.05) increase in expression compared to undifferentiated control cells. Neurogenic transdifferentiation of EMSCs exhibited distinctive dendritic morphology with axon projections and neuronal specific genes, NFM, NGF, MBP, NES, B3T and MAP2 and proteins, B3T, NFM, NGF, and TRKA were positively expressed in neuronal differentiated cells. Functional analysis of neuronal differentiated EMSCs displayed voltage-dependence and kinetics for transient outward K+ currents (Ito), at holding potential of -80 mV, Na+ currents and during current clamp, neuronal differentiated EMSCs was more negative than that of control EMSCs. Porcine EMSCs is a suitable model for studying molecular mechanism of transdifferentiation, assessment of electrophysiological properties and their efficiency during in vivo transplantation.
Scratch Detection on Hard Disk Drive Media to Reduce Head Disk Interaction and Prevent Data Loss (2021)

Abstract Accurately detecting irregularities in the media — thermal asperities and delamination — and mapping them out from further usage is critical to prevent data loss and minimize head disk interaction (HDI). Defect growth is a common concern in hard disk drives (HDD) and the immediate vicinity of media defects are also mapped out to provide sufficient protection against defect growth. A class of media defects that prove more complex to protect against defect growth is scratches on the media. Margining a media scratch involves filling in the gaps between the components of a scratch and margining the vicinity of the scratch in the defect growth direction. While Hough transform based techniques and deeplearning models have been developed to identify media patterns, they cannot be implemented in the hard disk drive firmware due to memory and computational limitations. Here, we present a computationally simple and efficient alternative to identify scratches on the media by combining clustering and an iterative parameter estimation to fit a line to the scratch in noisy conditions. The result is a method that is capable of modeling linear, spiral and parabolic scratches on a media and fill gaps in the scratch and extend the margining at either end of the scratch.
Meningococcal Group C Subgroup Determinant Detected by Immunofluorescence (1976)

SummaryThe presence or absence of a meningococcal Group C subgroup antigen (C1+) can be detected by immunofluorescence as readily as by a previously reported hemagglutination-inhibition method. When compared in strains isolated from cases and carriers, subgroup negative (C1-) strains seemed to occur more often in cases. The subgroup antigen is widely distributed geographically. The characterization of meningococci by its presence or absence may be of value in epidemiological studies.
Sprayed Organic Electrophosphorescent Devices with Small Organic Molecules (2005)

Sprayed organic electrophosphorescent devices with small organic molecules have been investigated. By heating the entire spray system, i.e., a spray gun and a glass substrate, a high device performance without leakage current has been realized. Using the green electrophosphorescent molecule fac tris(2-phenyl-pyridine)iridium Ir(ppy) 3 as a doped material, device performance with a maximum luminance of 18,400 cd/m 2 , a maximum luminous power efficiency of 20.9 lm/W, and a maximum quantum efficiency of 16.9% could be obtained. By mixing blue and red electrophosphorescent molecules of iridium(III) bis(2-(4,6-difluorophenyl) pyridinato- N ,C2') picolinate (FIrpic) and iridium(III) bis(2-(2'-benzothienyl) pyridinato- N ,C3') (acetylacetonate) (Btp 2 Ir(acac)), white emission with Commission Internationale d'Eclairage chromaticity coordinates of (0.33, 0.34) is also achieved.

SARA: A session aware infrastructure for high performance next generation cluster-based servers (2007)

Internet server clustering has been widely used by operators to improve the scalability and the availability of the rendered services under heavy load condition. Load balancing is a well known mean to optimize the usage of the cluster available resources by fairly allocating them to the offered network traffic. Most state-of-the-art research advocate either session oblivious or coarse grained session aware load balancing architectures. While guaranteeing session integrity, the coarse grained session awareness leads to an unfair allocation of the cluster resources. In this work, we advocate an innovative fine grained session aware load balancing architecture of an offered IP traffic to a cluster of Internet servers. The proposed architecture aims to maximize the cluster useful throughput in terms of completed sessions per unit of time. It provides high availability capabilities in case of failure of the legitimate entry point to the cluster. Finally, it is fully client transparent and is open to adapt to any multiple-flow based NGN service such as voice over IP or video streaming.
The Treatment of Acidosis in Acute Lung Injury with Tris-Hydroxymethyl Aminomethane (THAM) (2000)

Mechanical hyperventilation of acidemic patients with acute lung injury (ALI) requires the use of high volumes and pressures that may worsen lung injury. However, permissive hypercapnia in the presence of shock, metabolic acidosis, and multi-organ system dysfunction may compromise normal cellular function. Tris-hydroxymethyl aminomethane (THAM) may be an effective method to control acidosis in this circumstance. Protonated THAM is excreted by the kidneys, so that carbon dioxide production is not raised. In an uncontrolled study, we administered THAM to 10 patients with acidosis (mean pH = 7.14) and ALI (mean lung injury score = 3.28) in whom adequate control of arterial pH could not be maintained during either eucapnic ventilation or permissive hypercapnia ventilation. THAM was given at a mean dose of 0.55 mmol/kg/h. Administration of THAM was associated with significant improvements in arterial pH and base deficit, and a decrease in arterial carbon dioxide tension that could not be fully accounted for by ventilation. Although further studies are needed to confirm these observations, THAM appears to be an effective alternative to sodium bicarbonate for treating acidosis during ALI.

Leishmaniasis Vaccination (2001)

In the history of vaccine development, key observations have gradually led to our ability to take rational approaches toward the induction of protective immunity to microbial pathogens. The earliest efforts consisted of inoculating lesion material into healthy individuals resulting in the then inexplicable prevention of the development of similar disease. Centuries later, after researchers found that microscopic forms were responsible for the major human diseases such as tuberculosis and smallpox, vaccines consisting of inoculating weakened or attenuated organisms were developed. The discovery of the cell populations that mediate antibody and cellular immune responses, followed by the identification of the cytokine mediators of cellular immunity and the ability to identify, isolate, purify, and produce antigenic molecules of various pathogens has permitted a rational approach toward vaccine development. Perhaps no disease model has been more widely used to understand the roles of cell populations and cytokines in mediating disease susceptibility and resistance than the infection of inbred mice with the Leishmania parasite 1. For example, BALB/c mice infected subcutaneously with Leishmania major develop nonhealing, disseminated, fatal infections, whereas C57BL mice similarly infected are more resistant, and heal their infections. In addition to susceptibility factors determined by host genetics, it has recently been appreciated that the insect that transmits leishmania to humans may play a key role in the establishment of infection. The study by Valenzuela et al. in this issue 2 exploits this information in what may prove to be a unique approach to vaccination.
Influence of Alumina Addition on Low Temperature Degradation of Y<sub>2</sub>O<sub>3</sub>-Coated Powder Based Y-TZP Ceramics (2014)

The influence of the addition of 0.25, 2 and 5 wt.% alumina on the mechanical properties and low temperature degradation (LTD) behaviour of 3 mol% yttria-coated ZrO 2 powder based Y-TZP ceramics was investigated, and compared to commercial powder based co-precipitated 3Y-TZPs with 0-0.25 wt.% Al 2 O 3 addition. The ceramics were subjected to accelerated hydrothermal degradation in an autoclave in H 2 O at 134°C up to 40 hrs. X-ray diffraction and Raman spectroscopy were used to assess the LTD behaviour. Incorporating the Y 2 O 3 stabilizer by means of a coating method resulted in a higher LTD resistance without compromising the higher fracture toughness, compared to the co-precipitation method. Alumina addition did not significantly influence the mechanical properties of all Y-TZPs but significantly increased the LTD resistance of the Y-TZP ceramics. The LTD resistance of 0.25 wt% Al 2 O 3 doped TZPs was substantially higher than that of ceramics containing 2 or 5 wt.% Al 2 O 3 , which had a comparable susceptibility. The highest LTD resistance for the 0.25 wt.% alumina doped ceramics could be correlated to the solubility limit of alumina in zirconia.

Optimal drug dosing control for intensive care unit sedation by using a hybrid deterministic–stochastic pharmacokinetic and pharmacodynamic model (2012)

SUMMARY In clinical intensive care unit practice, sedative/analgesic agents are titrated to achieve a specific level of sedation. The level of sedation is currently based on clinical scoring systems. Examples include the motor activity assessment scale, the Richmond agitation–sedation scale, and the modified Ramsay sedation scale. In general, the goal of the clinician is to find the drug dose that maintains the patient at a sedation score corresponding to a moderately sedated state. This is typically done empirically, administering a drug dose that usually is in the effective range for most patients, observing the patient's response, and then adjusting the dose accordingly. However, the response of patients to any drug dose is a reflection of the pharmacokinetic and pharmacodynamic properties of the drug and the specific patient. In this paper, we use pharmacokinetic and pharmacodynamic modeling to find an optimal drug dosing control policy to drive the patient to a desired modified Ramsay sedation scale score.

3D wide field-of-view Gabor-domain optical coherence microscopy advancing real-time in-vivo imaging and metrology (2017)

Real-time volumetric high-definition wide-field-of-view in-vivo cellular imaging requires micron-scale resolution in 3D. Compactness of the handheld device and distortion-free images with cellular resolution are also critically required for onsite use in clinical applications. By integrating a custom liquid lens-based microscope and a dual-axis MEMS scanner in a compact handheld probe, Gabor-domain optical coherence microscopy (GD-OCM) breaks the lateral resolution limit of optical coherence tomography through depth, overcoming the tradeoff between numerical aperture and depth of focus, enabling advances in biotechnology. Furthermore, distortion-free imaging with no post-processing is achieved with a compact, lightweight handheld MEMS scanner that obtained a 12-fold reduction in volume and 17-fold reduction in weight over a previous dual-mirror galvanometer-based scanner. Approaching the holy grail of medical imaging – noninvasive real-time imaging with histologic resolution – GD-OCM demonstrates invariant resolution of 2 &mu;m throughout a volume of 1 x 1 x 0.6 mm<sup>3</sup>, acquired and visualized in less than 2 minutes with parallel processing on graphics processing units. Results on the metrology of manufactured materials and imaging of human tissue with GD-OCM are presented.
Method and system for detecting an explosive (2023)

A method and system for detecting at least one explosive in a vehicle using a neutron generator and a plurality of NaI detectors. Spectra read from the detectors is calibrated by performing Gaussian peak fitting to define peak regions, locating a Na peak and an annihilation peak doublet, assigning a predetermined energy level to one peak in the doublet, and predicting a hydrogen peak location based on a location of at least one peak of the doublet. The spectra are gain shifted to a common calibration, summed for respective groups of NaI detectors, and nitrogen detection analysis performed on the summed spectra for each group.

Large format PACE HgCdTe FPA performance (1991)

In addition to several 256 × 256 devices with 40-μm pitch (which are the largest high-sensitivity HgCdTe hybrids currently available), we are presently developing a 640 × 480, 27-μm pitch device and a 320 × 240, 30-μm pitch device for the MWIR (3–5 μm) spectral band. The 256 × 256 hybrids are made with PACE-1 (Producible Alternative to CdTe for Epitaxy; HgCdTe-on-sapphire) detector material. The 640 × 480 will use recently developed PACE-3 (HgCdTe-on-silicon) material.
Application heartbeats (2010)

The rise of multicore computing has greatly increased system complexity and created an additional burden for software developers. This burden is especially troublesome when it comes to optimizing software on modern computing systems. Autonomic or adaptive computing has been proposed as one method to help application programmers handle this complexity. In an autonomic computing environment, system services monitor applications and automatically adapt their behavior to increase the performance of the applications they support. Unfortunately, applications often run as performance black-boxes and adaptive services must infer application performance from low-level information or rely on system-specific ad hoc methods. This paper proposes a standard framework, Application Heartbeats, which applications can use to communicate both their current and target performance and which autonomic services can use to query these values.
Widely tunable, narrow-linewidth, subnanosecond pulse generation in an electronically tuned Ti:sapphire laser (1999)

Widely tunable subnanosecond Ti:sapphire laser radiation pumped with a cw Q -switched laser-diode-pumped Nd:YAG laser has been demonstrated in a simple laser system with a configuration of variable cavity length. Laser wavelengths can be continuously tuned by adjustment of the rf of an intracavity acousto-optic tunable filter with a computer through the whole range of the laser gain. During tuning of the whole spectral range, there is no need to realign any optics in the laser, except for moving the mirror to track the change of the rf. The peak powers of the output pulses at a pump level of 300 mW are comparable with those of conventional tunable picosecond Ti:sapphire lasers at a cw pump level of almost 10 W.
