Understanding and Enhancing Catalyst Performance in AEM Electrolyzers Using a Statistical Approach (2021)

The behavior of the anode electrode in the Anion Exchange Membrane Water Electrolyzer (AEMWE) – where the oxygen evolution reaction (OER) occurs – is complex and influenced by several factors. Very few studies have been performed to understand OER electrode performance by optimizing contributing individual factors that influence the performance. This study highlights the individual effects of: catalyst loading, catalyst selection, gas diffusion layer (GDL) type and conductive additive content. The influence of each factor is elucidated through a Design of Experiments (DoE) approach with a full statistical analysis. Electrochemical data, alongside Pareto charts, parametric trends and their mutual interactions will be presented. Such a DoE approach is also helpful in making useful predictions, allowing new combinations to be discovered and tested. The end result is very high performance with a current density of 1 A/cm 2 at 1.64 V in 0.1 M KOH being achieved. Furthermore, we extend our understanding from this electrolyzer work, coupled with our previous electrode engineering for AEM fuel cells [1-3] to design electrodes for an AEM-based Unitized Regenerative Fuel Cell (URFC). Good baseline performance was achieved, including a round trip efficiency of 40.7 % at 500 mA/cm 2 . This study will serve as a guide for optimal electrode design with insights into design-performance compromises, which can be especially helpful when making design choices and performing techno-economic analyses.

Capture Kinetics of Electron Traps in MBE-Grown n-GaN (2001)

The carrier capture kinetics of the Ec—0.59 eV and Ec—0.91 eV electron traps found in molecular beam epitaxy (MBE)-grown n-GaN have been determined by means of deep level transient spectroscopy (DLTS). The 0.59 eV trap does not show the behaviour of either ideal point defects or line defects. In contrast, the 0.91 eV trap displays the kinetics of linearly arranged interacting point defects, which generate a time-dependent local Coulombic potential with a characteristic time constant of ≈ 8.6 μs.

Exploring Fine-Grained Audiovisual Categorization with the SSW60 Dataset (2022)

We present a new benchmark dataset, Sapsucker Woods 60 (SSW60), for advancing research on audiovisual fine-grained categorization. While our community has made great strides in fine-grained visual categorization on images, the counterparts in audio and video fine-grained categorization are relatively unexplored. To encourage advancements in this space, we have carefully constructed the SSW60 dataset to enable researchers to experiment with classifying the same set of categories in three different modalities: images, audio, and video. The dataset covers 60 species of birds and is comprised of images from existing datasets, and brand new, expert-curated audio and video datasets. We thoroughly benchmark audiovisual classification performance and modality fusion experiments through the use of state-of-the-art transformer methods. Our findings show that performance of audiovisual fusion methods is better than using exclusively image or audio based methods for the task of video classification. We also present interesting modality transfer experiments, enabled by the unique construction of SSW60 to encompass three different modalities. We hope the SSW60 dataset and accompanying baselines spur research in this fascinating area.
Nitroxide-Containing Amphiphilic Random Terpolymers for Marine Antifouling and Fouling-Release Coatings (2023)

Two types of amphiphilic random terpolymers, poly(ethylene glycol methyl ether methacrylate)-<i>ran</i>-poly(2,2,6,6-tetramethylpiperidinyloxy methacrylate)-<i>ran</i>-poly(polydimethyl siloxane methacrylate) (PEGMEMA-<i>r</i>-PTMA-<i>r</i>-PDMSMA), were synthesized and evaluated for antifouling (AF) and fouling-release (FR) properties using diverse marine fouling organisms. In the first stage of production, the two respective precursor amine terpolymers containing (2,2,6,6-tetramethyl-4-piperidyl methacrylate) units (PEGMEMA-<i>r</i>-PTMPM-<i>r</i>-PDMSMA) were synthesized by atom transfer radical polymerization using various comonomer ratios and two initiators: alkyl halide and fluoroalkyl halide. In the second stage, these were selectively oxidized to introduce nitroxide radical functionalities. Finally, the terpolymers were incorporated into a PDMS host matrix to create coatings. AF and FR properties were examined using the alga <i>Ulva linza</i>, the barnacle <i>Balanus improvisus</i>, and the tubeworm <i>Ficopomatus enigmaticus</i>. The effects of comonomer ratios on surface properties and fouling assay results for each set of coatings are discussed in detail. There were marked differences in the effectiveness of these systems against the different fouling organisms. The terpolymers had distinct advantages over monopolymeric systems across the different organisms, and the nonfluorinated PEG and nitroxide combination was identified as the most effective formulation against <i>B. improvisus</i> and <i>F. enigmaticus</i>.
High speed, wide velocity dynamic range Doppler optical coherence tomography (Part IV): split spectrum processing in rotary catheter probes (2014)

We report a technique for blood flow detection using split spectrum Doppler optical coherence tomography (ssDOCT) that shows improved sensitivity over existing Doppler OCT methods. In ssDOCT, the Doppler signal is averaged over multiple sub-bands of the interferogram, increasing the SNR of the Doppler signal. We explore the parameterization of this technique in terms of number of sub-band windows, width and overlap of the windows, and their effect on the Doppler signal to noise in a flow phantom. Compared to conventional DOCT, ssDOCT processing has increased flow sensitivity. We demonstrate the effectiveness of ssDOCT in-vivo for intravascular flow detection within a porcine carotid artery and for microvascular vessel detection in human pulmonary imaging, using rotary catheter probes. To our knowledge, this is the first report of visualizing in-vivo Doppler flow patterns adjacent to stent struts in the carotid artery.
Closing-the-Loop: A Data-Driven Framework for Effective Video Summarization (2020)

Today, videos are the primary way in which information is shared over the Internet. Given the huge popularity of video sharing platforms, it is imperative to make videos engaging for the end-users. Content creators rely on their own experience to create engaging short videos starting from the raw content. Several approaches have been proposed in the past to assist creators in the summarization process. However, it is hard to quantify the effect of these edits on the end-user engagement. Moreover, the availability of video consumption data has opened the possibility to predict the effectiveness of a video before it is published. In this paper, we propose a novel framework to close the feedback loop between automatic video summarization and its data-driven evaluation. Our Closing-The-Loop framework is composed of two main steps that are repeated iteratively. Given an input video, we first generate a set of initial video summaries. Second, we predict the effectiveness of the generated variants based on a data-driven model trained on users' video consumption data. We employ a genetic algorithm to search the space of possible summaries (i.e., adding/removing shots to the video) in an efficient way, where only those variants with the highest predicted performance are allowed to survive and generate new variants in their place. Our results show that the proposed framework can improve the effectiveness of the generated summaries with minimal computation overhead compared to a baseline solution - 28.3% more video summaries are in the highest effectiveness class than those in the baseline.

Oxidation and frictional performance of solid lubricants used in weapon stronglinks (1996)

The oxidation and performance of the solid film lubricant used in a majority of the surety devices in the enduring stockpile have been investigated. Oxidation of this lubricant in air at 150 C produces a significant increase in the molybdenum oxide to sulfide ratio, indicative of degradation of the primary lubricating constituent of the composite lubricant. Oxidation is more extensive on samples that were burnished such that the substrate is exposed over a fraction of the surface, relative to those which were only lightly burnished. Friction results indicate that oxidation in air did not increase the initial or steady-state friction coefficient for lightly burnished surfaces. However, surfaces burnished to expose substrate material experienced a significant increase in both initial and steady-state friction. Oxidation of lubricated parts retrieved from aged stronglinks has also been demonstrated.
Acquired Humoral Immunity toCryptococcus neoformans (2014)

Research initiated in the late 1980s has been the driving force behind a major expansion of one's knowledge about Ab immunity (AI) to cryptococcal disease (cryptococcosis) and a sea change in the understanding of mechanisms of AI to Cryptococcus neoformans and other microbes for which AI is not thought to be the predominant protective host defense mechanism. This chapter highlights this information, placing emphasis on how new knowledge about AI to C. neoformans has advanced one's understanding of pathogenesis, virulence, and mechanisms of Ab action. Levels of IgG to glucuronoxylomannan (GXM) were higher in human immunodeficiency virus (HIV)-infected than HIV-uninfected individuals in studies using a direct GXM capture enzyme-linked immunosorbent assay (ELISA), but lower in studies using different ELISA methods. The major effect of monoclonal Ab (MAb) to GXM on effector cell function is achieved by enhancing expression of costimulatory molecules, cytokine receptors, and cytokines that polarize the cellular response toward a Th1-like response. A long-recognized mechanism that is central to AI to cryptococcal disease is Ab-mediated clearance of GXM. The remarkable expansion of knowledge about AI to cryptococcal disease since the late 1980s has already translated into potential therapies to ameliorate human cryptococcal disease. The study of AI to C. neoformans has provided precedents that have informed and influenced one's views on Ab immunity in general and the efficacy of Abs against other microbes.
(Invited) Low-Temperature Growth of Strained Germanium Quantum Wells for High Mobility Applications (2020)

The extremely high hole mobilities attainable in strained germanium quantum wells (QW) provide a unique pathway to develop novel devices in the emerging field of quantum electronics. A major challenge associated with the growth of Ge QW structures using the industrial standard reduced-pressure chemical vapor deposition (RP-CVD) technique is the incorporation of unintentional impurities in the growing film. We will show that a compromise exists between the growth conditions that minimize the various impurities (mainly O and Si) and the abruptness of the QW. The purity of the incoming gas plays a central role in this compromise and will be discussed.
Gestational hypertensive disorders and retinal microvasculature: the Generation R Study (2017)

Compared to women with a previous normotensive pregnancy, women with pre-eclampsia and gestational hypertension show an altered status of the microvasculature 6 years after the index pregnancy. This is reflected by smaller retinal arteriolar calibers and wider retinal venular calibers. These microvascular changes may possibly contribute to the development of cardiovascular disease in later life.

Bone formation beyond the skeletal envelope using calcium phosphate granules packed into a collagen pouch—a pilot study (2023)

In this proof-of-concept, bone neoformation beyond the skeletal envelope is explored by using a collagen pouch (<i>n</i>= 6) packed with calcium phosphate (CaP) granules placed over the frontal bone in sheep (<i>n</i>= 3). At 13 weeks, macroscopic examination showed specimens covered by an adherent fibrinous envelope with slight vascularization. Histology revealed colonization of the implant by newly formed woven bone and fibrous connective tissue. Surface osteoblasts as well as material-filled macrophages, lymphocytes, polymorphonuclear cells and giant cells were also found in large quantities surrounding the newly formed bone tissue inside the collagen pouch. On the side facing the recipient bone, the collagen membrane had to a large extent been resorbed and bridging bone formation was clearly visible between the test article and recipient bone. On the other side facing soft tissue, the collagen pouch remained intact with a visible fibrous capsule. This study demonstrated that the use of a collagen sleeve as a container for CaP granules allows for good neoformation beyond the skeletal envelope with bridging bone formation clearly visible between the test article and recipient bone. Additionally, in this model, macrophages rather than osteoclasts appear to modulate CaP granule resorption and remodeling into new bone. This construct opens new perspectives for treatment methods that could be used for bone augmentation and restoration of cranio-maxillofacial defects and malformations.
Scalability of Carbon Nanotube FET-based Circuits (2006)

In this paper, we studied the scalability of CNT-based devices and circuits. We focused mainly on SB CNFETs and determined 1-1,5 nm to be an optimum tube diameter to achieve the best performance-power trade-off We established that CNTs have a potential in logic applications. We introduced FOA metric and showed improvement over Si-based MOSFETs and we extended our discussion toward scalability of CNFETs. CNTs are potentially a promising novel material to be integrated into future technology generations if research communities can collectively address some of the barriers and fabrication challenges this material system is facing.
A New Iridium(III) Complex as a Deep-Red Phosphorescent Emitter in Organic Light-Emitting Diodes (2016)

We synthesized a novel red-emitting iridium(III) complex, bis[2-(5-(9H-carbazole-9-yl)thiophene-2-yl)benzo[d]thiazole]iridium(III)acetylacetonate ([(CTBT)21 r(acac)]), for use in phosphorescent organic light-emitting diodes. The photophysical and electrochemical properties of [(CTBT)2Ir(acac)] were characterized using photoluminescence (PL) and cyclic voltammetry. The photophysical properties of [(CTBT)2Ir(acac)] included PL emission at 630 nm. The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels of [(CTBT)2Ir(acac)] were calculated to be -5.14 and -2.83 eV, respectively. Phosphorescent organic light-emitting diodes with a configuration of ITO/PEDOT:PSS (30 nm)/TAPC (30 nm)/TPBi (12.5 nm):TCTA (12.5 nm):dopant (3%, 5%, 10%)/TSPO1 (35 nm)/LiF (1 nm)/Al (100 nm) were fabricated and characterized. The fabricated device doped with 5% [(CTBT)2Ir(acac)] showed a high luminous efficiency of 2.06 cd/A, maximum external quantum efficiency of 4.32% at 4 V, maximum outstanding luminance of 398.8 cd/m2, and maximum power efficiency of 1.79 lm/W with Commission Internationale de L'Eclairage (CIE) coordinates of (0.69, 0.31).
Glutamate and Huntington's Disease (1981)

Very small injections of kainate (an analogue of the neurotransmitter, glutamate) into rat neostriatum have been shown to duplicate remarkably well neural and behavioural abnormalities seen in Huntington's disease (HD). This experimental procedure provided an excellent model system for investigating the pathogenesis and treatment of HD. Work with the animal model has suggested that abnormal glutamate neurotransmission may underline the neuropathological changes found in HD. At present, research is being performed on all aspects of this hypothesis in order to find possible beneficial treatments for sufferers of the disease.
Outcomes of Community-Dwelling Adults without Diabetes Mellitus Who Require Ambulance Services for Hypoglycemia (2012)

C-type lectin-like receptor 2 (CLEC-2)-dependent DC migration is controlled by tetraspanin CD37 (2017)

Abstract Cell migration is central to evoke a potent immune response. Dendritic cell (DC) migration to lymph nodes is dependent on the interaction of C-type lectin-like receptor 2 (CLEC-2) expressed by DCs, with podoplanin expressed by lymph node stromal cells (LNSCs). However, the underlying molecular mechanisms by which CLEC-2 influences DC migration remain elusive. Here, we show that CLEC-2-dependent DC migration is tightly controlled by tetraspanin CD37, a membrane-organizing protein. Our findings demonstrate a specific molecular interaction between CLEC-2 and CD37. Myeloid cells lacking CD37 ( Cd37-/- ) expressed less CLEC-2 on their surface compared to wild-type cells, indicating that CD37 is required to stabilize membrane expression of CLEC-2. In addition, CLEC-2-expressing DCs lacking CD37 showed impaired adhesion, migration velocity and displacement on LNSCs. Moreover, Cd37-/- DCs failed to form actin protrusions in a 3D collagen matrix upon podoplanin-induced CLEC-2 stimulation, phenocopying CLEC-2-deficient DCs (CD11c ΔCLEC-2 ). Microcontact printing experiments revealed that CD37 is required for CLEC-2 recruitment in the membrane to its ligand podoplanin. This study demonstrates that tetraspanin CD37 controls CLEC-2 membrane organization and provides new molecular insights underlying CLEC-2-dependent DC migration.
NON-CONTRAST MR LYMPHOGRAPHY OF RARE LYMPHATIC ABNORMALITIES (2021)

Detailed imaging of the lymphatic system often requires direct injection of contrast into lymph nodes which can be technically challenging, time consuming, and produce painful stimuli. We sought to describe the use of non-contrast MR lymphography (NCMRL) for normal controls and patients with a variety of rare disorders associated with lymphatic pathologies. Two control subjects and five affected patients (decompensated Fontan circulation, central conducting lymphatic abnormality, familial lymphedema and two with Gorham-Stout disease) were studied. NCMRL images were segmented in a semiautomated fashion and the major lymphatic channels and thoracic duct (TD) highlighted for identification. Adequate imaging was available for both controls and 4/5 affected patients; the youngest patient could not be imaged given patient motion. For the two controls, the TD was seen in the expected anatomic location. For the decompensated Fontan patient, there were numerous tortuous lymphatic channels, predominantly in the upper chest and neck. For the familial lymphedema patient, a TD was not identified; instead, peripheral lymphatic collaterals near the lateral chest walls. For the first Gorham- Stout patient, the TD was enlarged with large intrathoracic lymph collections. For the second Gorham-Stout patient, there were bilateral TD with lymph collections in vertebral bodies. Using NCMRL, we were able to image normal and abnormal lymphatic systems. An important learning point is the potential need for sedation for younger patients due to long image acquisition times and fine resolution of the structures of interest.
On the performance of learned data structures (2021)

A recent trend in algorithm design consists of augmenting classic data structures with machine learning models, which are better suited to reveal and exploit patterns and trends in the input data so to achieve outstanding practical improvements in space occupancy and time efficiency. This is especially known in the context of indexing data structures for big data where, despite few attempts in evaluating their asymptotic efficiency, theoretical results are yet missing in showing that learned indexes are provably better than classic indexes, such as B-tree s and their variants. In this paper, we present the first mathematically-grounded answer to this problem by exploiting a link with a mean exit time problem over a proper stochastic process which, we show, is related to the space and time complexity of these learned indexes. As a corollary of this general analysis, we show that plugging this result in the (learned) PGM-index, we get a learned data structure which is provably better than B-tree s.
