Design and Implementation of an Assistive Real‐Time Red Lionfish Detection System for AUV/ROVs (2018)

In recent years, the Pterois Volitans, also known as the red lionfish, has become a serious threat by rapidly invading US coastal waters. Being a fierce predator, having no natural predator, being adaptive to different habitats, and being with high reproduction rates, the red lionfish has enervated current endeavors to control their population . This paper focuses on the first steps to reinforce these efforts by employing autonomous vehicles. To that end, an assistive underwater robotic scheme is designed to aid spear - hunting divers to locate and more efficiently hunt the lionfish. A small - sized, open source ROV with an integrated camera is programmed using Deep Learning methods to detect red lionfish in real time. Dives are restricted to a certain depth range, time, and air supply. The ROV program is designed to allow the divers to locate the red lionfish before each dive, so that they can plan their hunt to maximize their catch. Lightweight, portability, user - friendly interface, energy efficiency, and low cost of maintenance are some advantages of the proposed scheme. The developed system’s performance is examined in areas currently invaded by the red lionfish in the Gulf of Mexico. The ROV has shown success in detecting the red lionfish with high confidence in real time.

Performance simulation and verification of a continuously variable planetary (CVP) transmission (2016)

Traction drive mechanisms and their fluids have been the subject of test, research and modeling for more than half a century. However, it cannot be said that traction drives have been in common use until the more recent commercialization of continuously variable transmissions (CVTs) in the automotive industry. Today the fruit from decades of development are seen by the introduction of toroidal and belt type CVTs in both conventional drivetrain and hybrid drivetrain vehicles. These up and coming applications require valid modeling and simulation methods which represent component interaction at the traction interface. The focus of this thesis is the implementation of a dynamic system simulation of a continuously variable planetary (CVP) transmission. Modeling of the traction interface is developed using rigid-plastic and elastic-plastic assumptions of traction fluid behavior. This general model is correlated with published fluid traction data at steady state operating conditions. The general traction model is further implemented within a dynamic system model and compared with test stand data from a CVP transmission. It is shown that the traction model correlates adequately with power transmission but poorly with secondary forces, specifically shift forces.
Effect of Method of Preparation of Cu-Zn-Al Catalysts on DME Synthesis (2007)

A series of Cu-Zn-Al catalysts from the precursors with the hydrotalcite-like structure were prepared, and these catalysts admixed with γ-Al2O3 were tested for DME synthesis in a fixed bed flow reactor in a single step. DME synthesis rates were well correlated with the Cu metal surface of the Cu-Zn-Al catalysts in the admixed catalysts, indicating that DME synthesis rates would be controlled by methanol synthesis rates.
Reconfigurable Compute-In-Memory on Field-Programmable Ferroelectric Diodes (2022)

The deluge of sensors and data generating devices has driven a paradigm shift in modern computing from arithmetic-logic centric to data-centric processing. Data-centric processing require innovations at device level to enable novel compute-in-memory (CIM) operations. A key challenge in construction of CIM architectures is the conflicting trade-off between the performance and their flexibility for various essential data operations. Here, we present a transistor-free CIM architecture that permits storage, search and neural network operations on sub-50nm thick Aluminum Scandium Nitride ferroelectric diodes (FeDs). Our circuit designs and devices can be directly integrated on top of Silicon microprocessors in a scalable process. By leveraging the field-programmability, non-volatility and non-linearity of FeDs, search operations are demonstrated with a cell footprint &lt; 0.12 um2 when projected onto 45-nm node technology. We further demonstrate neural network operations with 4-bit operation using FeDs. Our results highlight FeDs as candidates for efficient and multifunctional CIM platforms.
Precipitation Sequence of Al&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;/Al-Cu-Mg and Al-Mg-Si Composite Materials (2000)

Precipitation sequence of the Al 2 O 3 /Al-Cu-Mg and Al-Mg-Si composite materials were investigated by high resolution transmission electron microscope (HRTEM) and differential scanning calorimeter (DSC). Precipitation sequence of the Al 2 O 3 /Al-Cu-Mg composite material changed from that of Al-Cu-Mg alloy (GPB zones S') to that of Al-Cu alloy (GP zone → θ) based on results by HRTEM observation. Precipitation sequence of the Al 2 O 3 /Al-Mg-Si composite material was similar to that of an Al-Mg 2 Si alloy including Si in excess (excess Si alloy). A DSC curve of an Al 2 O 3 /Al-Mg-Si composite material was not in agreement with that of an Al-Mg 2 Si alloy. Major peaks in DSC curve of this composite were not clear and this behavior was similar to that of an excess Si alloy including lower Mg 2 Si contents rather than a quasi-binary Al-Mg 2 Si alloy.
The influence of trace water concentration on iron oxide nanoparticle size (2008)

The size of iron oxide nanoparticles, prepared from the thermal decomposition of Fe(CO)(5) in a high boiling solvent in the presence of oleic acid, is affected by water concentration, giving particles from sizes of 5.6 nm to as low as 2.2 nm.

Morphology of ventricular septal defects in complete transposition. Surgical implications. (1992)

Postmortem examination of 62 hearts with complete transposition (concordant atrioventricular and discordant ventriculoarterial connections) and an accompanying ventricular septal defect was performed to determine the morphologic variability of ventricular septal defects and to explore the surgical implications of these defects. Particular attention was directed toward assessing alignment of the outlet septum relative to the muscular septum. Coronary arterial distributions were also evaluated, but specific patterns of distribution did not correlate with morphology of the defect. Of 49 hearts with a normally aligned outlet septum, there were 24 perimembranous, 21 muscular, and 2 doubly committed and juxtaarterial defects. Two hearts had both perimembranous and muscular defects. Twelve of the 21 muscular defects were "central," being surrounded entirely by muscle and located just below the leaflets of the pulmonary valve, and 9 were located in the inlet or apical trabecular septum. There were 13 hearts with malalignment of the outlet septum, anteriorly in 11 and posteriorly in 2. All with anterior malalignment had a subpulmonary defect that was perimembranous in 7 and muscular in 4. Both defects with posterior malalignment had a subaortic perimembranous defect. Because variations in morphology of a ventricular septal defect have a direct impact on selection of the most suitable surgical repair, specific operative approaches are discussed.
Popular Culture and Individual Empowerment in the Global World (2015)

Popular culture studies are central to the study of Liberal Arts, which enhance the spirit of the academia. They help people to understand their own culture, appreciate it, and grow up as participating members of the community. The present study focuses attention to analyze popular culture in relation to the domains of governance and self-help literature. The study is significant because it helps understand the trajectory adopted for individual empowerment. Existence of multicultural societies across the Globe is more in the present day as the world has become a global village. It can, therefore, be understood that popular culture studies are imminent for promoting goodwill and mutual understanding among members of different societies. One of the major facets in this respect is politics, which focuses on governing of a state. In tune with the changing trends, political parties need to update and upgrade their strategies to influence the emotions of people through several means. Self-Help Books (SHBs) emphasize on the individual well-being while cutting across the social and psychological barriers in terms of culture. It is an established fact that, millions of SHBs are sold annually worldwide with promises of making a person slimmer, calmer, smarter, richer and more attractive. Individual empowerment has always been the central focus throughout the world cultures. The present study is significant as it helps to analyze and understand popular culture in relation to the governing of human life by the State and the individual over himself.
Pitfalls in Monitoring Tacrolimus (FK 506) (1997)

Tacrolimus (FK 506) is a new, potent immunosuppressive drug for primary and rescue therapy in liver and kidney transplantation. Therapeutic drug monitoring is essential for this drug because of its narrow therapeutic window. Blood levels are monitored routinely by enzyme linked immunoassay (ELISA) or by microparticle enzyme immunoassay (MEIA). In a 13-year-old recipient of a liver transplant who had poor hepatic function during the first postoperative week, the authors observed unusually high tacrolimus blood concentrations using either the ELISA (26.6 to 49.0 microg/l) or MEIA (58.5 to 64.5 microg/l). Parent drug levels measured in the same blood samples by high-performance liquid chromatography/mass spectrometry (HPLC/MS) were up to 10-fold lower (5.1 to 9.0 microg/l). The discrepancies between the immunoassay and HPLC/MS results could not be attributed to any of the known metabolites of tacrolimus.
The Impact of Extracellular Vesicle-Encapsulated Circulating MicroRNAs in Lung Cancer Research (2014)

Lung cancer is the leading cause of cancer-related deaths. Biomarkers for lung cancer have raised great expectations in their clinical applications for early diagnosis, survival, and therapeutic responses. MicroRNAs (miRNAs), a family of short endogenous noncoding RNAs, play critical roles in cell growth, differentiation, and the development of various types of cancers. Current studies have shown that miRNAs are present in the extracellular spaces, packaged into various membrane-bound vesicles. Tumor-specific circulating miRNAs have been developed as early diagnostic biomarkers for lung cancer. Remarkably, some studies have succeeded in discovering circulating miRNAs with prognostic or predictive significance. Extracellular vesicles (EVs), such as exosomes and microvesicles, are recognized as novel tools for cell-cell communication and as biomarkers for various diseases. Their vesicle composition and miRNA content have the ability to transfer biological information to recipient cells and play an important role in cancer metastasis and prognosis. This review provides an in-depth summary of current findings on circulating miRNAs in lung cancer patients used as diagnostic biomarkers. We also discuss the role of EV miRNAs in cell-cell communication and explore the effectiveness of these contents as predictive biomarkers for cancer malignancy.
New &lt;i&gt;in vitro&lt;/i&gt; SPF Evaluation Method for Hydrophilic Sunscreen Samples (2021)

A new method was developed for the in vitro sun protection factor (SPF) evaluation of sunscreen samples. A new type of substrate, a hydroxyalkyl cellulose-coated plate, was also prepared specifically for hydrophilic samples. This new substrate was required because hydrophilic samples would be unlikely to wet the surface of the standard cosmetic PMMA UV evaluation plate. A super-hydrophilic quartz plate was prepared by corona-discharge treatment before an aqueous solution of hydroxyalkyl cellulose was spread on it. A flat and uniform hydroxyalkyl cellulose film was subsequently formed through the evaporation of water. Special care was taken to inhibit the generation of spatial non-uniformity. Six hydrophilic sunscreen samples with in vivo SPF values of 56, 55, 52, 25, 15, and 4, were then applied to the prepared hydroxyalkyl cellulose-coated plate, as well as a super-hydrophilic quartz plate and a flat hydrophobic PMMA plate. The thicknesses of the applied layers were determined using a wheel-shaped wet film thickness gauge immediately after the application, and UV transmission was measured using an SPF analyzer. The value of in vitro SPF was calculated from the UV absorbance and the thickness of the layer. For two out of the six samples, PMMA plate could not be available, as the samples were unable to wet the PMMA surface. Relatively small differences were observed between the in vitro SPF values when the super-hydrophilic and hydroxyalkyl cellulose-coated plates were used. Samples exhibiting higher in vivo SPF were also associated with higher in vitro SPF values, although a linear relationship was not observed. In contrast to the super-hydrophilic plate whose half-life of the super-hydrophilicity is only approximately five days, the hydrophilicity of the hydroxyalkyl cellulose-coated plate scarcely varied during six months of storage. Finally, a simplified evaluation method was also proposed. The validity of the method was verified through a ring test where three researchers employed this method in different laboratories at three independent organizations.
People in books (2012)

We introduce People in Books with FlashCam technology, a system that supports children and long-distance family members to act as characters in children's storybooks while they read stories together over a distance. By segmenting the video chat streams of the child and remote family member from their background surroundings, we create the illusion that the child and adult reader are immersed among the storybook illustrations. The illusion of inhabiting a shared story environment helps remote family members feel a sense of togetherness and encourages active reading behaviors for children ages three to five. People In Books is designed to fit into families' traditional reading practices, such as reading ebooks on couches or in bed via netbook or tablet computers. To accommodate this goal we implemented FlashCam, a computationally cost effective and physically small background subtraction system for mobile devices that allows users to move locations and change lighting conditions while they engage in background-subtracted video communications. A lab evaluation compared People in Books with a conventional remote reading application. Results show that People in Books motivates parents and children to be more performative readers and encourages open-ended play beyond the story, while creating a strong sense of togetherness.
Connective Tissue Growth Factor–Specific Monoclonal Antibody Therapy Inhibits Pancreatic Tumor Growth and Metastasis (2006)

Pancreatic cancer is highly aggressive and refractory to most existing therapies. Past studies have shown that connective tissue growth factor (CTGF) expression is elevated in human pancreatic adenocarcinomas and some pancreatic cancer cell lines. To address whether and how CTGF influences tumor growth, we generated pancreatic tumor cell lines that overexpress different levels of human CTGF. The effect of CTGF overexpression on cell proliferation was measured in vitro in monolayer culture, suspension culture, or soft agar, and in vivo in tumor xenografts. Although there was no effect of CTGF expression on proliferation in two-dimensional cultures, anchorage-independent growth (AIG) was enhanced. The capacity of CTGF to enhance AIG in vitro was linked to enhanced pancreatic tumor growth in vivo when these cells were implanted s.c. in nude mice. Administration of a neutralizing CTGF-specific monoclonal antibody, FG-3019, had no effect on monolayer cell proliferation, but blocked AIG in soft agar. Consistent with this observation, anti-CTGF treatment of mice bearing established CTGF-expressing tumors abrogated CTGF-dependent tumor growth and inhibited lymph node metastases without any toxicity observed in normal tissue. Together, these studies implicate CTGF as a new target in pancreatic cancer and suggest that inhibition of CTGF with a human monoclonal antibody may control primary and metastatic tumor growth.
Chapter 13. Hyperpolarized Xenon Biosensors and HyperCEST (2015)

Xenon based biosensors are molecules that couple target binding events to NMR detection of specifically associated changes in xenon NMR signals. There are many variations that enable high sensitivity detection of the presence of target molecules though changes in the chemical shift of xenon, or the spatial distribution of such molecules when biosensors are tethered to a target. The strong NMR signals that can be obtained through hyperpolarization of xenon, and amplification by chemical exchange, allow detection of molecules at nanomolar concentrations and below, far lower than the normal limit for NMR. The variety of sensors that have already been constructed is reviewed, and shows that the principles are quite general, and xenon biosensors should be applicable in many chemical and biological sensing applications. Xenon biosensor development remains an active area, new ways of targeting are being developed, and further optimizations may yield even higher sensitivity.
Autoantibody Responses and Pathology Regulated by B7-1 and B7-2 Costimulation in MRL/ <i>lpr</i> Lupus (2000)

The activation of T lymphocytes requires both Ag-mediated signaling through the TCR as well as costimulatory signals transmitted through B7-1 and/or B7-2 with CD28. The interference of B7-mediated costimulatory signals has been proposed as one immunotherapeutic intervention for the prevention autoimmune disease. This study has examined autoantibody responses and autoimmune pathology in a murine model of human systemic lupus erythematosus (SLE), the MRL-lpr/lpr mouse, genetically deficient in B7-1 or B7-2, or in mice treated with B7-1/B7-2 blocking Abs. In contrast to other studies of murine models of SLE, MRL-lpr/lpr mice treated with B7 blocking Abs exhibit strong anti-small nuclear ribonucleoprotein (snRNP) and anti-DNA autoantibody responses with some changes in isotype switching as compared with untreated animals. All MRL-lpr/lpr mice deficient in B7-1 or B7-2 produce anti-snRNP and anti-DNA titers with isotypes virtually identical with wild-type animals. However, the absence of B7-2 costimulation did interfere with the spontaneous activation and the accumulation of memory CD4+ or CD8+ T lymphocytes characteristic of wild-type MRL-lpr/lpr mice. IgG and C3 complement deposition was less pronounced in the kidneys of B7-2 deficient MRL-lpr/lpr mice, reflecting their lessor degree of glomerulonephritis. By comparison, B7-1-deficient MRL-lpr/lpr mice had more severe IgG and C3 deposits in glomeruli.
Nitride Metallic Bipolar Plates for Proton Exchange Membrane Fuel Cells (2004)

Thermal nitridation of Ni- and Fe-base Cr-bearing alloys is under investigation as a means to enable use of metallic bipolar plates in proton exchange membrane fuel cells. Proof of principle for this approach was recently established by a successful single-cell fuel cell test using 50 cm2 active area anode and cathode plates made from a model nitrided Ni-50Cr alloy. Protection of the metal was accomplished by the formation of an electrically-conductive and corrosion-resistant CrN/Cr2N surface layer. This paper presents an overview of efforts to form similar Cr-nitride surfaces on Ni-Cr and Fe-Cr base alloys in commercially available composition ranges.
The oesophageal string test: a novel, minimally invasive method measures mucosal inflammation in eosinophilic oesophagitis (2012)

Changing Demographics of Patients with Total Joint Replacement (2006)

There has been a substantial change in the population demographics of patients who potentially will require total joint replacements. We studied data regarding temporal trends in physical condition, life expectancy, education, and other population demographics of individuals most likely to receive total joint replacements. Changes in this population during the last several decades correlate with temporal changes in the prevalence of joint disease and the incidence of total hip and knee replacements. Compared with several decades ago, patients currently receiving total joint replacements are almost 20% heavier, more physically active, three times more likely to have a high school or college education, and live more than 25% longer. Patients needing total joint replacements are more likely to be female, and twice as likely to receive a total knee replacement than a total hip replacement. Treatment choices and outcome expectations are best determined with accurate knowledge of current surgical science and current patient demographics. Therefore, it is important to realize that today's population most likely to receive total joint replacements is demographically different than in the past.
PMUT Array Design for mid-air Haptic feedback (2022)

Generating tactile sensation in mid-air has been widely demonstrated using an array of bulk piezoelectric transducers [1], [2]. Recently, micromachined devices have shown to be a valid alternative for this application [3], providing advantages in terms of form factor, resolution, ease of integration with supporting electronics and robustness. This paper describes the design of PMUT for short range mid-air haptic application. Circular PMUT and donut-shaped PMUT are investigated, and simulations are compared to measurements. Finally, a 1 by 1 cm silicon chip, containing 400um Aluminum Nitride PMUTs, is designed and characterized for delivering enough pressure to generate mid-air haptic feedback.

Correction of likelihoods for degrees of freedom in robust speech recognition using missing feature theory (2003)

In missing feature theory (MFT), noise robustness of speech recognizers is obtained by modifying the likelihood computed by the acoustic model to express that some features extracted from the signal are unreliable or missing. In one implementation of MFT, the acoustic model and bounds on the unreliable feature are used to infer an estimate of the missing data. This paper addresses an observed bias of the likelihood evaluated at the estimate. Theoretical and experimental evidence are provided that an upper bound on the accuracy is improved by applying a computationally simple correction for the number of free variables in the likelihood maximization.
Phase-Matched Third-Harmonic Generation in a Nematic Liquid Crystal Cell (1999)

We show the generation of a strong phase-matched third harmonic in a simple parallel nematic liquid crystal cell. A single laser beam of femtosecond pulses is used to deform the internal structure of the molecular orientation distribution, and to generate the third harmonic from the twisted structure that is formed. Up to ${10}^{\ensuremath{-}5}$ of the laser power was converted to the third harmonic, in a volume as small as 5 $\ensuremath{\mu}{\mathrm{m}}^{3}$.
