Synthesis and Thermal Transport Studies of Nanofluids Based on Metal Decorated Photochemically Oxidized Multiwalled Carbon Nanotubes (2012)

Nanoparticle fluid suspensions were prepared using photochemically functionalized multiwalled carbon nanotubes in polar base fluids. Multiwalled carbon nanotubes prepared by catalytic chemical vapour deposition technique have been functionalized by irradiating with ultraviolet light of wavelength 254 nm. The photochemical oxidation of multiwalled carbon nanotubes under UV irradiation introduces oxygen containing functional groups onto the surface of the nanotubes, generating new defects on their structure. Silver nanoparticles have been deposited over multiwalled carbon nanotubes by chemical method. The enhancement in thermal conductivity of the prepared nanofluids using functionalized multiwalled carbon nanotubes and Ag nanoparticles deposited functionalized multiwalled carbon nanotubes with volume fraction, temperature and aspect ratio has been demonstrated. Silver deposited functionalized multiwalled carbon nanotubes based nanofluids in DI water with 0.02% volume fraction exhibit a thermal conductivity enhancement of 9.9% and 47% at room temperature and at 50 degrees C respectively.

Prospects for Treatment of Pediatric Vitreoretinal Diseases with Vascular Endothelial Growth Factor Inhibition (2009)

While angiogenesis inhibitors are already widely used to treat retinal disease in adults, only limited reports are currently available for the use of anti-VEGF in pediatric vitreoretinal diseases such as retinopathy of prematurity, Coats' disease, familial exudative vitreoretinopathy and retinopathy of incontinentia pigmenti. The limited trials of anti-VEGF therapy for pediatric vitreoretinal diseases are promising, although more extensive controlled trials will be needed to confirm their safety and efficacy. This paper will examine the current evidence for use of anti-VEGF therapy in a number of pediatric vitreoretinal disorders and describe a case of anti-VEGF therapy in retinopathy of incontinentia pigmenti.
Tissue engineering of blood vessels (2006)

Complete incorporation into host tissues and the maintenance of a viable and self-renewing endothelial layer are the fundamental goals to be achieved when developing a tissue-engineered blood vessel. Sourcing of cells and modulating their interaction with extracellular matrix and supporting scaffold have been the focus of intense research. Although the use of tissue-engineered blood vessels in humans is so far limited, advances in our knowledge of stem cell precursors and the development of new biomaterials should enable this technology to reach routine clinical practice within a decade.
Theoretical Analysis of Tunable Three-Section Slotted Fabry–Perot Lasers Based on Time-Domain Traveling-Wave Model (2013)

In this paper, we present a simple time-domain traveling-wave dynamic model for the simulation of wavelength tunable three-section slotted Fabry-Perot (3s-SFP) semiconductor lasers. The longitudinal spatial hole burning, the nonlinear gain compression, and the refractive index changes with carrier density are included in this model. The slot structure is characterized by using the boundary conditions of the optical fields propagating through the slot facets. For the first time, the tuning mechanism of the 3s-SFP laser is studied in detail by using the proposed model. Characteristics of the 3s-SFP laser including the lasing wavelength, the side-mode suppression ratio, the output spectrum, and the wavelength switching dynamics are simulated. The potential of increasing the tuning range of the 3s-SFP laser is also discussed by optimizing design parameters of the device. Virtual digital infinite-impulse response bandpass filters with different central wavelengths are developed to examine the mode power of different channels during wavelength switching events. Switching times of approximately 2-5 ns are demonstrated theoretically. Good agreements have been found between the simulation results and the experimental measurements.
IMAGE STABILIZATION BY KALMAN FILTERING USING A CONSTANT VELOCITY CAMERA MODEL WITH ADAPTIVE PROCESS NOISE (2001)

An image sequence stabilization system based on adaptive Kalman filtered smoothing of global camera motion is presented in this paper. The global camera displacement is modelled in the form of a constant velocity motion model, that is applied to the Kalman filter to ensure smooth global displacements. The process noise variance of the Kalman filter is varied adaptively according to former correction vectors, to prevent the correction vector from exceeding the permitted frame shift limit, while achieving successful stabilization.

Time Domain Discrete Fourier Domain Mode Locked Laser With k-Space Uniform Comb Lines (2021)

Frequency comb swept lasers or wavelength stepped swept lasers with comb filters have been proposed in optical domain subsampling or circular-ranging optical coherence tomography (OCT) to achieve high axial scan rate and extended imaging range with a given acquisition bandwidth. However, the comb filters lack flexibility in varying the free spectral range (FSR). In this article, we propose and demonstrate a novel discrete Fourier domain mode locked (FDML) laser by using intracavity optical intensity modulation. Swept signals with comb lines uniformly distributed in the frequency domain is generated with tailor-made pulse patterns according to the sweep trace of the swept filter. Discrete k-space uniform swept signals with different FSRs and pulse durations are generated in the same laser. The FDML laser discretized by temporal modulation is more stable than that with a comb filter. The discrete FDML lasers will be potential sources of OCT and the fast-developing swept source LiDAR.
Predictors of Colorectal Cancer Screening Variation Among Primary-Care Providers and Clinics (2013)

Variation in CRC screening exists among primary-care clinics and providers within a single clinic. Predictors of variation can be identified at patient, provider, and clinic levels. Quality improvement interventions addressing CRC screening need to be directed at multiple levels of the health-care system.
Application of the PSP investigation of the oscillating pressure fields (1998)

The paper reviews the main problems encountered during investigations of the Oscillating Pressure Fields by the Pressure Sensitive Paint (PSP) technique. Measurement methodology, theoretical and experimental estimations of the PSP response time are presented. It is shown that currently available pressure sensitive paint formulations can be used for oscillation frequencies up to 20 Hz. The first experimental results obtained in the Transonic Wind Tunnel of DLR, Gottingen (TWG), on the pitching wing model are presented.
Light Stabilisers (2002)

The degradation pathways for polymeric materials and coatings under the influence of light and oxygen are presented and the consequent need for light-protecting agents (light stabilisers) is discussed. The mechanisms of action of hindered amine light stabilisers and certain UV-absorbers are explained. The use of light stabilisers in photographic-, automotive- and wood-coatings as well as cosmetic applications is described.
Sensitivity and permissivity of Cyprinus carpio to cyprinid herpesvirus 3 during the early stages of its development: importance of the epidermal mucus as an innate immune barrier (2014)

Cyprinid herpesvirus 3 (CyHV-3) causes a lethal disease in common and koi carp (Cyprinus carpio). The present study investigated the ability of CyHV-3 to infect common carp during the early stages of its development (from embryos to fingerlings) after inoculation by immersion in water containing the virus. Fish were inoculated at different times after hatching with a pathogenic recombinant CyHV-3 strain expressing luciferase. The sensitivity and permissivity of carp to CyHV-3 were investigated using in vivo bioluminescence imaging. The susceptibility of carp to CyHV-3 disease was investigated by measuring the survival rate. Carp were sensitive and permissive to CyHV-3 infection and susceptible to CyHV-3 disease at all stages of development, but the sensitivity of the two early developmental stages (embryo and larval stages) was limited compared to later stages. The lower sensitivity observed for the early developmental stages was due to stronger inhibition of viral entry into the host by epidermal mucus. In addition, independent of the developmental stage at which inoculation was performed, the localization of light emission suggested that the skin is the portal of CyHV-3 entry. Taken together, the results of the present study demonstrate that carp are sensitive and permissive to CyHV-3 at all stages of development and confirm that the skin is the major portal of entry after inoculation by immersion in infectious water. The results also stress the role of epidermal mucus as an innate immune barrier against pathogens even and especially at the early stages of development.
Evaluation of Manufacturing Expert Systems: Framework and Model (1992)

ABSTRACT A great deal of attention has been given to the use of expert systems in solving manufacturing problems by software development experts as well as application experts. However, the evaluation of expert systems in manufacturing applications has received very little attention in the literature. Whether or not an expert system is justified for a particular manufacturing environment depends on the expert system's effectiveness on both the manufacturing problem and the problem environment. An expert system may be evaluated according to the effectiveness of its ability to solve problems (interpret, predict, diagnose, design, plan, monitor, debug, repair, instruct, and control), interface with users, and handle knowledge (learn, represent, induce, and retrieve). It may also be evaluated on other aspects such as expandability, responsiveness, or simply its costs. However, it is difficult to measure all the costs and benefits of an manufacturing expert system and to perform a traditional economic analysis. Hence, we propose the use of a decision theoretic technique. This paper provides a model to evaluate expert systems for manufacturing problems. This model can be implemented within the framework of an Analytic Hierarchy Process developed by Saaty [23]. It is applicable for evaluating expert systems developed for manufacturing problem areas such as process planning, assembly, quality control, scheduling, production automation, maintenance, machine tools selection, equipment layout, and material handling.
Using Common Spatial Distributions of Atoms to Relate Functionally Divergent Influenza Virus N10 and N11 Protein Structures to Functionally Characterized Neuraminidase Structures, Toxin Cell Entry Domains, and Non-Influenza Virus Cell Entry Domains (2015)

The ability to identify the functional correlates of structural and sequence variation in proteins is a critical capability. We related structures of influenza A N10 and N11 proteins that have no established function to structures of proteins with known function by identifying spatially conserved atoms. We identified atoms with common distributed spatial occupancy in PDB structures of N10 protein, N11 protein, an influenza A neuraminidase, an influenza B neuraminidase, and a bacterial neuraminidase. By superposing these spatially conserved atoms, we aligned the structures and associated molecules. We report spatially and sequence invariant residues in the aligned structures. Spatially invariant residues in the N6 and influenza B neuraminidase active sites were found in previously unidentified spatially equivalent sites in the N10 and N11 proteins. We found the corresponding secondary and tertiary structures of the aligned proteins to be largely identical despite significant sequence divergence. We found structural precedent in known non-neuraminidase structures for residues exhibiting structural and sequence divergence in the aligned structures. In N10 protein, we identified staphylococcal enterotoxin I-like domains. In N11 protein, we identified hepatitis E E2S-like domains, SARS spike protein-like domains, and toxin components shared by alpha-bungarotoxin, staphylococcal enterotoxin I, anthrax lethal factor, clostridium botulinum neurotoxin, and clostridium tetanus toxin. The presence of active site components common to the N6, influenza B, and S. pneumoniae neuraminidases in the N10 and N11 proteins, combined with the absence of apparent neuraminidase function, suggests that the role of neuraminidases in H17N10 and H18N11 emerging influenza A viruses may have changed. The presentation of E2S-like, SARS spike protein-like, or toxin-like domains by the N10 and N11 proteins in these emerging viruses may indicate that H17N10 and H18N11 sialidase-facilitated cell entry has been supplemented or replaced by sialidase-independent receptor binding to an expanded cell population that may include neurons and T-cells.
Staging of Bilateral Lung Transplantation for High-Risk Patients With Interstitial Lung Disease: One Lung at a Time (2016)

The choice of a single or bilateral lung transplant for interstitial lung disease (ILD) is controversial, as surgical risk, long-term survival and organ allocation are competing factors. In an effort to balance risk and benefit, our center adopted a staged bilateral lung transplant approach for higher surgical risk ILD patients where the patient has a single lung transplant followed by a second single transplant at a later date. We sought to understand the surgical risk, organ allocation and early outcomes of these staged bilateral recipients as a group and in comparison to matched single and bilateral recipients. Our analysis demonstrates that staged bilateral lung transplant recipients (n = 12) have a higher lung allocation score (LAS), lower pulmonary function tests and a lower glomerular filtration rate prior to the first transplant compared to the second (p < 0.01). There was a shorter length of hospital stay for the second transplant (p = 0.02). The staged bilateral compared to the single and bilateral case-matched controls had comparable short-term survival (p = 0.20) and pulmonary function tests at 1 year. There was a higher incidence of renal injury in the conventional bilateral group compared to the single and staged bilateral groups. The staged bilateral procedure is a viable option in select ILD patients.

Piriformospora indica affects plant growth by auxin production (2007)

Piriformospora indica has been shown to improve the growth of many plant species including Arabidopsis thaliana, but the mechanism by which this is achieved is still unclear. Arabidopsis root colonization by P. indica was examined in sterile culture on the medium of Murashige and Skoog. P. indica formed intracellular structures in Arabidopsis root epidermal cells and caused changes in root growth, leading to stunted and highly branched root systems. This effect was because of a diffusible factor and could be mimicked by IAA. In addition, P. indica was shown to produce IAA in liquid culture. We suggest that auxin production affecting root growth is responsible for, or at least contributes to, the beneficial effect of P. indica on its host plants.
Study on Quality Characteristics of Korean Traditional Kukhwaju by Addition of Dried Chrysanthemum indicum L. Extract into Mash (2015)

본 연구에서는 요록에 기록되어 있는 양조법으로 감국 열수추출물 첨가량을 달리하여 국화주를 제조하고 그에 따른 품질 특성의 연구를 목적으로 pH, 알코올 농도, 산도, 환원당함량, 총 페놀 함량과 DPPH radical 소거 활성 능력을 측정하였으며, 유리당, 유기산 함량 분석, 색도 측정을 통한 이화학적 실험을 하였다. pH 측정 실험에서는 감국 열수추출물이 투입되지 않은 control을 제외한 각각의 시료가 pH 5.0 이상에서 발효가 시작되어 2일이 경과한 때에 급격하게 pH 3.5까지 낮아졌다. 이후 pH 3.5에서 pH 3.9 사이에서 큰 변화 없이 발효가 끝날 때까지 유지하였다. 산도는 lactic acid(%)로 나타내었으며 pH 수치와는 반대로 1일이 경과하였을 때 급격히 상승하였다. 이후 pH 수치와 마찬가지로 급격한 변화를 보이다가 4일이 경과하면서 반응이 완만해졌다. pH와 산도 측정에서는 감국 열수추출물을 투입하지 않은 시료와 투입한 시료와의 차이가 크지 않았다. 알코올 농도의 변화에서는 4일이 경과할 때까지 급격히 상승하였으나 이후로는 완만하게 상승하여 6일 이후로는 그 상태를 유지하였다. 이는 환원당의 함량 변화와 반비례하며 4일이 경과한 후로는 반응이 완만해졌다. 알코올 농도와 환원당 함량의 변화 역시 pH와 산도에서의 변화처럼 큰 차이를 보이지 않았다. 총 페놀 함량은 gallic acid(mg/L)로 나타내었으며 감국 열수추출물의 첨가량이 일정량 이상일 경우에만 감국 열수추출물 비첨가군보다 총 페놀 함량이 높게 측정되었다. 실험으로 감국 열수추출물의 첨가로 양조한 국화주의 항산화 효과를 증대시키려면 5% 이상을 넣어야 효과를 볼 수 있는 것으로 나타났다. 유리당은 모든 시료에서는 arabinose가 가장 많이 함유되어 있는 것으로 나타났으며, glucose와 maltose, xylose는 소량으로 함유되어 있고 mannose는 5%, 10% 감국 열수추출물을 첨가한 국화주만 함유되어 있었다. 유기산 측정 시 감국 열수추출물 양에 비례해서 대체로 증가로 나타났다. 본 실험의 결과를 토대로 감국의 기능성 측면의 심도 있는 연구가 필요할 거라 생각되며 이는 감국을 이용한 식품개발에 있어서도 좋은 기초자료가 될 것이라 생각한다.
Usefulness of MRI in preoperative evaluation of local invasion of thoracoabdominal desmoid tumor. A case report. (1999)

症例は44歳の男性.左胸腹壁に2回の局所再発を来したデスモイド腫瘍に対し腫瘍摘出術, 左胸腹壁合併切除術及び右腹直筋皮弁による胸腹壁再建術を施行した.デスモイド腫瘍はCTでは周囲筋組織との境界の判別が困難であったが, T2強調MRIでは腫瘍は筋組織に比しで高信号を呈し周囲筋組織との判別が容易であった.また, MRI矢状断で上下に先細り状に浸潤する腫瘍が明瞭に描出された.MRIではデスモイド腫瘍は周囲筋組織と異なった信号を呈すること, 任意の方向で撮影可能であることから術前の局所浸潤範囲の評価に有用であった.
A Shift from Diffusion Assisted to Energy Transfer Controlled Fluorescence Quenching in Polymer–Fullerene Photovoltaic Blends (2012)

Singlet exciton diffusion and decay dynamics were investigated in two conjugated polymers: the high performance photovoltaic material, PCDTBT, and the substituted poly(p-phenylenevinylene), MEH-PPV, blended with fullerenes. Polymer fluorescence dynamics were measured on a planar quenching interface and in blends with varying concentrations of fullerene acceptor. At very low concentrations of fullerene, fluorescence quenching is assisted by exciton diffusion in the polymer, whereas direct Förster-type energy transfer to the fullerene is found to be the dominant mechanism at higher fullerene concentrations. The rate of quenching in the diffusion-assisted regime is found to be consistent with exciton diffusion coefficients calculated from the fluorescence quenching on a planar interface. The results also show that in unannealed films the onset of phase segregation occurs at concentrations of 4 wt % of C61-PCBM in MEH-PPV and 7 wt % of C71-PCBM in PCDTBT and that fullerenes remain dispersed as single molecules within polymer films below this concentration threshold.
Distal humeral plating of an intramedullary nail periprosthetic fracture using a miss-a-nail technique: a case report (2009)

The treatment of distal humeral periprosthetic fractures is not widely described in the literature. We present a difficult clinical scenario of a 72-year-old man who sustained a displaced distal humeral periprosthetic fracture about a Polarus Plus intramedullary nail. In this case, stable fixation was achieved using bicondylar Acumed Mayo congruent Plates using a miss-a-nail technique. Four months following the post operative period, the patient regained satisfactory range of movement with full function and no further complications up to 18 months post fixation. Treatment of such complex periprosthetic fractures is technically achievable and with potentially good results.
Closed Reduction of Tibial Plateau Fractures (1988)

One hundred tibial plateau fractures in 96 patients were treated at three teaching hospitals. Seventy-three fractures were treated by closed reduction and early mobilization of the knee using a cast brace. Twelve fractures in this group also had percutaneous pin fixation under fluoroscopic control. The end results were graded by clinical functional criteria and by roentgenographic criteria. Eighty-nine percent of the patients treated by closed reduction methods had good to excellent functional results with a low complication rate (12%). Observations based on long-term roentgenographic examinations did not correlate with the functional end results. Many patients with less than satisfactory roentgenographic results had good to excellent functional long-term results. The indications for operative stabilization of these fractures should be based on testing for knee stability in full extension, rather than on any arbitrary roentgenographic criteria. For unstable fractures, closed reduction using ligamentotaxis and percutaneous fixation supplemented by cast brace support proved effective and relatively free of complications.
Snugglebug (2009)

Symbolic analysis shows promise as a foundation for bug-finding, specification inference, verification, and test generation. This paper addresses demand-driven symbolic analysis for object-oriented programs and frameworks. Many such codes comprise large, partial programs with highly dynamic behaviors--polymorphism, reflection, and so on--posing significant scalability challenges for any static analysis. We present an approach based on interprocedural backwards propagation of weakest preconditions. We present several novel techniques to improve the efficiency of such analysis. First, we present directed call graph construction , where call graph construction and symbolic analysis are interleaved. With this technique, call graph construction is guided by constraints discovered during symbolic analysis, obviating the need for exhaustively exploring a large, conservative call graph. Second, we describe generalization , a technique that greatly increases the reusability of procedure summaries computed during interprocedural analysis. Instead of tabulating how a procedure transforms a symbolic state in its entirety, our technique tabulates how the procedure transforms only the pertinent portion of the symbolic state. Additionally, we show how integrating an inexpensive, custom logic simplifier with weakest precondition computation dramatically improves performance. We have implemented the analysis in a tool called Snugglebug and evaluated it as a bug-report feasibility checker. Our results show that the algorithmic techniques were critical for successfully analyzing large Java applications.
