Heat Transfer and Flow in a Short, Vertical, Internally Heated Annulus with a Rotating Outer Boundary (1972)

Experimental determinations were made of the steady-state heat fluxes and velocity profiles in water between two vertical concentric cylinders, the heated inner cylinder being stationary while the outer cylinder was rotated in ambient temperature air. Secondary flows, due to end effects, existed in the annulus at all rotational speeds and profoundly influenced the rate of heat transfer across the annulus. When the circulation of the secondary flows opposed those due to natural convection, the mean Nusselt number decreased almost to unity.
Fluorescent Conjugated Polymer-Stabilized Gold Nanoparticles for Sensitive and Selective Detection of Cysteine (2007)

We report a new fluorescent detection method for cysteine based on one-step prepared fluorescent conjugated polymer-stabilized gold nanoparticles. The as-prepared fluorescent conjugated polymer-stabilized gold nanoparticles fluoresce weakly due to the fluorescence resonance energy transfer between the fluorophore and the gold nanoparticles. Upon the addition of cysteine, a thiol-containing amino acid, the fluorescence of the colloidal solution increases significantly, indicating that cysteine can modulate the energy transfer between fluorophore and gold. This phenomenon then allows for sensitive detection of cysteine with a limit of detection (LOD) of 25 nM. The linear range of determination of cysteine is from 5 × 10-8 to 4 × 10-6 M. None of the other amino acids found in proteins interferes with the determination. Moreover, due to the excellent protecting ability of the fluorescent conjugated polymers, the synthesis of metal nanoparticles and modifying with fluorophores can be accomplished within one step, which makes our method much simpler than conventional methods. We also expect that it will be possible to detect other biologically important analytes based on the fluorescent conjugated polymer-stabilized metal nanoparticles.

Pilot-Aided Channel Estimation for Systems with Virtual Carriers (2006)

In this paper, we investigate various frequency-domain channel estimators for orthogonal frequency division multiplexing (OFDM) systems with virtual carriers (VCs). As conventional estimators cannot estimate the channel transfer function (CTF) at VCs, DFT-based estimators are not directly applicable in OFDM systems with VCs. To circumvent this, we present least squares (LS), generalized linear minimum mean square error (GLMMSE) and generalized singular value decomposition (GSVD) methods to estimate the CTF at VCs. Further, by exploiting the received data samples at VCs, we describe a novel noise variance estimation method. We also analyze the performance degradation due to estimated noise variance and the channel correlation mismatch. Performance comparison shows that the discrete Fourier transform (DFT)-based channel estimators incorporating the proposed CTF estimation at VCs achieve at least 6 dB gain when MMSE= 10-3 compared to frequency-domain LS estimator. Further, even though the DFT-based LS estimator with VCs performs worst among all the DFT-based estimators, it is the most robust estimator.
Large-mode-area double-clad fibers for pulsed and CW lasers and amplifiers (2004)

The advent of double clad fiber technology has made high power lasers and amplifiers possible. However, the scalability of output powers can be limited by amplified spontaneous emission and nonlinear processes such as stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS). These limitations can be overcome by using low numerical apertures (NAs), large-mode areas (LMAs), novel index profiles and high dopant concentrations. This paper discusses advances made in design and fabrication of highly efficient, large-mode area double clad fibers. Experimental and modeling results pertaining to changes in mode area, resultant power density and nonlinear threshold with changing core size are discussed. In addition, the mechanical reliability of the LMA fibers is discussed.
Resolution Enhancement for AR/VR Displays Based on LC Sub-pixel Frame Shift (2018)

We propose a resolution enhancement method for AR/VR displays based on sub-pixel frame shift. The resolution of the native display engine is doubled by synchronizing the display engine and a LC deflector. Experimental results using commercial electronic devices, Samsung Gear VR and Galaxy S8, show that the resolution is doubled and the screen door effect is reduced.
Hidden Markov model-based speech emotion recognition (2003)

In this contribution we introduce speech emotion recognition by use of continuous hidden Markov models. Two methods are propagated and compared throughout the paper. Within the first method a global statistics framework of an utterance is classified by Gaussian mixture models using derived features of the raw pitch and energy contour of the speech signal. A second method introduces increased temporal complexity applying continuous hidden Markov models considering several states using low-level instantaneous features instead of global statistics. The paper addresses the design of working recognition engines and results achieved with respect to the alluded alternatives. A speech corpus consisting of acted and spontaneous emotion samples in German and English language is described in detail. Both engines have been tested and trained using this equivalent speech corpus. Results in recognition of seven discrete emotions exceeded 86% recognition rate. As a basis of comparison the similar judgment of human deciders classifying the same corpus at 79.8% recognition rate was analyzed.
Maturation/M-Phase Promoting Factor: A Regulator of Aging in Porcine Oocytes1 (2000)

Deterioration in the quality of mammalian oocytes during the metaphase-II arrest period is well known as "oocyte aging." Oocytes in which aging has occurred are called aged oocytes, and these oocytes show enhanced activation and higher fragmentation rates after parthenogenetic activation. Previously we showed that porcine aged oocytes had low maturation/M-phase promoting factor (MPF) activity, and we suggested that this low MPF activity contributed at least in part to the aging phenomena. In the present study, we examined the relationship between MPF activity and these aging phenomena by artificially regulating MPF activity in porcine metaphase-II-arrested oocytes. Since we have shown recently that aged porcine oocytes contain abundant phosphorylated inactive MPF, so-called pre-MPF, we used vanadate and caffeine, which affect the phosphorylation status of MPF, to regulate MPF activity. Incubation of 48-h-matured oocytes with vanadate for 1 h increased the phosphorylation of MPF and decreased MPF activity. The parthenogenetic activation and fragmentation rates were significantly increased compared with those of control oocytes. Conversely, treatment of 72-h-cultured aged oocytes with caffeine (last 10 h of culture) decreased the level of pre-MPF and elevated MPF activity. These oocytes revealed significantly lower parthenogenetic activation rates and a lower percentage of fragmentation than did untreated aged oocytes. These results indicate that not only the increased ability for parthenogenetic activation but also the increased fragmentation rate observed in porcine aged oocytes may be attributable in part to the gradual decrease in MPF activity during prolonged culture. Control of MPF phosphorylation with these agents may allow for some degree of manipulation of oocyte aging.

Finite element analysis for the evaluation of the structural behaviour, of a prosthesis for trans-tibial amputees (2011)

The finite element analysis (FEA) has been identified as a useful tool for the stress and strain behaviour determination in lower limb prosthetics. The residual limb and prosthetic socket interface was the main subject of interest in previous studies. This paper focuses on the finite element analysis for the evaluation of structural behaviour of the Sure-flex™ prosthetic foot and other load-bearing components. A prosthetic socket was not included in the FEA. An approach for the finite element modelling including foot analysis, reverse engineering and material property testing was used. The foot analysis incorporated ground reaction forces measurement, motion analysis and strain gauge analysis. For the material model determination, non-destructive laboratory testing and its FE simulation was used. A new, realistic way of load application is presented along with a detailed investigation of stress distribution in the load-bearing components of the prosthesis. A novel approach for numerical and experimental agreement determination was introduced. This showed differences in the strain on the pylon between the experimental and the numerical model within 30% for the anteroposterior bending and up to 25% for the compression. The highest von Mises stresses were found on the foot-pylon connecting component at toe off. Peak stress of 216MPa occurred on the posterior adjusting screw and maximum stress of 156MPa was found at the neck of the male pyramid.

Heterogeneous Network Embedding via Deep Architectures (2015)

Data embedding is used in many machine learning applications to create low-dimensional feature representations, which preserves the structure of data points in their original space. In this paper, we examine the scenario of a heterogeneous network with nodes and content of various types. Such networks are notoriously difficult to mine because of the bewildering combination of heterogeneous contents and structures. The creation of a multidimensional embedding of such data opens the door to the use of a wide variety of off-the-shelf mining techniques for multidimensional data. Despite the importance of this problem, limited efforts have been made on embedding a network of scalable, dynamic and heterogeneous data. In such cases, both the content and linkage structure provide important cues for creating a unified feature representation of the underlying network. In this paper, we design a deep embedding algorithm for networked data. A highly nonlinear multi-layered embedding function is used to capture the complex interactions between the heterogeneous data in a network. Our goal is to create a multi-resolution deep embedding function, that reflects both the local and global network structures, and makes the resulting embedding useful for a variety of data mining tasks. In particular, we demonstrate that the rich content and linkage information in a heterogeneous network can be captured by such an approach, so that similarities among cross-modal data can be measured directly in a common embedding space. Once this goal has been achieved, a wide variety of data mining problems can be solved by applying off-the-shelf algorithms designed for handling vector representations. Our experiments on real-world network datasets show the effectiveness and scalability of the proposed algorithm as compared to the state-of-the-art embedding methods.
Three-dimensional conformal breast irradiation in the prone position (2003)

The prone position can be used for the planning of adjuvant radiotherapy after conservative breast surgery in order to deliver less irradiation to lung and cardiac tissue. In the present study, we compared the results of three-dimensional conformal radiotherapy planning for five patients irradiated in the supine and prone position. Tumor stage was T1N0M0 in four patients and T1N1M0 in one. All patients had been previously submitted to conservative breast surgery. Breast size was large in three patients and moderate in the other two. Irradiation in the prone position was performed using an immobilization foam pad with a hole cut into it to accommodate the breast so that it would hang down away from the chest wall. Dose-volume histograms showed that mean irradiation doses reaching the ipsilateral lung were 8.3+/-3.6 Gy with the patient in the supine position and 1.4+/-1.0 Gy with the patient in the prone position (P = 0.043). The values for the contralateral lung were 1.3+/-0.7 and 0.3+/-0.1 Gy (P = 0.043) and the values for cardiac tissue were 4.6+/-1.6 and 3.0+/-1.7 Gy (P = 0.079), respectively. Thus, the dose-volume histograms demonstrated that lung tissue irradiation was significantly lower with the patient in the prone position than in the supine position. Large-breasted women appeared to benefit most from irradiation in the prone position. Prone position breast irradiation appears to be a simple and effective alternative to the conventional supine position for patients with large breasts, since they are subjected to lower pulmonary doses which may cause less pulmonary side effects in the future.
Effect of induction temperature on the production of malaria antigens in recombinant <i>E. coli</i> (1989)

As part of a process development campaign, studies have been conducted to determine the influence of induction temperature on the expression of two different malaria antigens, RN1 and RT2. Single-step temperature inductions, in which growth at 32.0 degrees C is followed by a shift in temperature to a desired setpoint, show that there exists an optimum duration and temperature of induction which is product specific. Between an induction temperature of 39.5 and 44.5 degrees C RN1 yield is constant at ca. 0.20 g/g total soluble protein (TSP). RT2 yield approaches 0.20 g/g TSP only at elevated induction temperatures. The optimum temperature of induction for RN1 production is 39.5 degrees C, whereas, that for RT2 production is 41.0 degrees C. Above the optimum temperature of induction antigen concentration decreases owing to decreases in biomass. Furthermore, the maximum concentration of these two antigens differ by a factor of four. With increasing temperature of induction the extent of proteolysis of the products also appears to increase.
A EXPERIMENTAL STUDY ON THE DESIGN OF MIX PROPORTION OF UNSATURATED POLYESTER RESIN MORTAR IN CONSIDERATION OF ITS VISCOSITY (1986)

The yield value of unsaturated polyester resin mortar is not clearly observed and the viscosity of resin varies depending upon the change of temperature and the mix proportions of diluent. Therefore, it is difficult to decide the mix proportions of the resin mortar according to the same design procedure as that of cement mortar.In order to make clear the relation between the mix proportions of resin mortar and its workability, viscosity, flow, and segregation tests were carried out. From these test results, the workability of the resin mortar was found to be estimated by the viscosity of resin and resin paste.Based on the results, the mix design of the resin mortar with a constant viscosity is proposed in this paper.
Acetylsalicylic acid modulates inflammation and insulin resistance in a mouse model of diet-induced obesity (2015)

Extensive scientific evidence indicates that non-optimal diet and sedentary lifestyle constitute some of the behaviors/risk factors associated with the onset of many diseases with significant societal impact, such as obesity. Chronic over-nutrition dramatically remodels adipose tissue architecture, driving adipocyte hypertrophy, oxidative stress and immune cell infiltration, followed by increased production of proinflammatory adipokines and cytokines that contribute to the progression of a chronic, low-grade inflammatory state (1,2). Obesity is associated with this inflammatory phenotype and increases the risk of chronic disease, including cardiovascular disease, as well as insulin resistance that predisposes to the development of type 2 diabetes (3). These obesity-associated diseases are subsequently linked to premature death, and reinforce the need to further define the complex relationship between inflammation and adipose tissue dysfunction. Reducing inflammation may represent a feasible disease-prevention strategy for obesity. Here we evaluate the effects of acetylsalicylic acid (ASA), a commercial small-molecule anti-inflammatory drug, in a mouse model of diet-induced obesity (DIO). The metabolic and inflammatory status and adipose tissue changes were evaluated by immunohistochemistry and Real time PCR in mice fed with high fat diet (HFD) compared with mice fed with standard diet (SD). We also analyzed how these events were modified as a result of treatment with ASA. Our results demonstrate that ASA not only displays anti-adiposity effects by reducing adipocyte hypertrophy and reversing insulin resistance, but that it also modulates adipose tissue inflammation. This could aid the optimization of clinical interventions and lifestyle changes aimed at improving human health.
THROUGH-THE-EARTH (TTE) COMMUNICATIONS SYSTEM AND THE IN-MINE POWER LINE (IMPL) COMMUNICATIONS SYSTEM (2002)

Work has progressed on both subsystems: the Through-the-Earth (TTE) Communications system and the In-Mine Power Line (IMPL) Communications system. The TTE system: The system was fabricated and repackaged as an industrial product enclosed in a commercial rugged, waterproof housing suitable for installation in mines. Features were added to the system to appeal to the preferences of different mine managers. Arrangements were made with NIOSH to install the system in the Lake Lynn underground mine for evaluation and demonstration to potential users. The IMPL system: Voice compression was successfully implemented and incorporated into the laboratory model. Compressed voice was transmitted through a power line, expanded at the receiving end, and received with high clarity.
Optimizing PCR for Mouse Genotyping: Recommendations for Reliable, Rapid, Cost Effective, Robust and Adaptable to High‐Throughput Genotyping Protocol for Any Type of Mutation (2019)

Genotyping consists of searching for a DNA sequence variation localized at a well-defined locus in the genome. It is an essential step in animal research because it allows the identification of animals that will be bred to generate and maintain a colony, euthanized to control the available space in the animal facility, or used in experiment protocols. Here we describe polymerase chain reaction (PCR) genotyping protocols for fast, sensitive, easy, and cost-effective characterization of mouse genotype. We discuss optimization of parameters to improve the reliability of each assay and propose recommendations for enhancing reproducibility and reducing the occurrence of inconclusive genotyping. All steps required for efficient genotyping are presented: tissue collection; sample verification and direct DNA lysis; establishment of a robust genotyping strategy with reliable, rapid, and cost-effective assays; and finally, transition to high-throughput automatized PCR, including mix miniaturization and automation. © 2019 The Authors.

Single-cell transcriptomics of human T cells reveals tissue and activation signatures in health and disease (2019)

Human T cells coordinate adaptive immunity in diverse anatomic compartments through production of cytokines and effector molecules, but it is unclear how tissue site influences T cell persistence and function. Here, we use single cell RNA-sequencing (scRNA-seq) to define the heterogeneity of human T cells isolated from lungs, lymph nodes, bone marrow and blood, and their functional responses following stimulation. Through analysis of >50,000 resting and activated T cells, we reveal tissue T cell signatures in mucosal and lymphoid sites, and lineage-specific activation states across all sites including distinct effector states for CD8<sup>+</sup> T cells and an interferon-response state for CD4<sup>+</sup> T cells. Comparing scRNA-seq profiles of tumor-associated T cells to our dataset reveals predominant activated CD8<sup>+</sup> compared to CD4<sup>+</sup> T cell states within multiple tumor types. Our results therefore establish a high dimensional reference map of human T cell activation in health for analyzing T cells in disease.
Large‐scale Gulf Stream frontal study using Geos 3 radar altimeter data (1978)

From data obtained by the Geos 3 radar altimeter, sea surface heights are found by both editing and filtering the raw sea surface height measurements and then referencing these processed data to a 5′ × 5′ geoid. Any trend between the processed data and the geoid is removed by subtracting out a linear fit to the residuals in the open ocean. Data from individual passes are further processed by applying a minimum variance technique at the subsatellite crossing points to produce surface topography maps for the 6 months and an overall mean map which reveal important details about the Gulf Stream system. The differences between the monthly mean and the overall mean are calculated for each of the 6 months to show the temporal and spatial changes of the Gulf Stream front and spawned eddies. The standard deviation map is even more informative and shows preferred locations of Gulf Stream meanders.
