Zooming Slow-Mo: Fast and Accurate One-Stage Space-Time Video Super-Resolution (2020)

In this paper, we explore the space-time video super-resolution task, which aims to generate a high-resolution (HR) slow-motion video from a low frame rate (LFR), low-resolution (LR) video. A simple solution is to split it into two sub-tasks: video frame interpolation (VFI) and video super-resolution (VSR). However, temporal interpolation and spatial super-resolution are intra-related in this task. Two-stage methods cannot fully take advantage of the natural property. In addition, state-of-the-art VFI or VSR networks require a large frame-synthesis or reconstruction module for predicting high-quality video frames, which makes the two-stage methods have large model sizes and thus be time-consuming. To overcome the problems, we propose a one-stage space-time video super-resolution framework, which directly synthesizes an HR slow-motion video from an LFR, LR video. Rather than synthesizing missing LR video frames as VFI networks do, we firstly temporally interpolate LR frame features in missing LR video frames capturing local temporal contexts by the proposed feature temporal interpolation network. Then, we propose a deformable ConvLSTM to align and aggregate temporal information simultaneously for better leveraging global temporal contexts. Finally, a deep reconstruction network is adopted to predict HR slow-motion video frames. Extensive experiments on benchmark datasets demonstrate that the proposed method not only achieves better quantitative and qualitative performance but also is more than three times faster than recent two-stage state-of-the-art methods, e.g., DAIN+EDVR and DAIN+RBPN.
Analytic Model of Four-switch Inverter-fed Driving System for Wye or Delta-connected Motor with Current Ripple Reduction Scheme (2016)

This paper proposes an analytic model for four-switch inverter (FSI)-driven wye (Y) or delta (&#x394;)-connected motors with a current ripple reduction algorithm. FSIs employ four switches in controlling three-phase load instead of using six switches. They have split dc-link stage, and due to this inherent structure there exists the voltage difference between upper and lower capacitors, which results in distortion of the inverter output voltage. To study characteristics of FSIs, this paper presents an advanced simulation models of FSI-driven control system for 3-phase motor that can has a wire connection either Y or &#x394;. In addition, this paper introduces a current ripple reduction scheme that mitigates degradation of control performance due to the voltage difference between the dc-link capacitors. The validity of the proposed method and the analytic model is verified by simulations and experiments carried out with 1-HP induction machine with Y or &#x394;-connection
Spectroscopic and Structural Properties of Bridge-Functionalized Dinuclear Coinage-Metal (Cu, Ag, and Au) NHC Complexes: A Comparative Study (2015)

Hydroxymethyl-functionalized methylene-bridged dinuclear N-heterocyclic bis(NHC) complexes with Ag(I) (2), Cu(I) (3) and Au(I) (4) have been synthesized and characterized by spectroscopic methods and X-ray diffraction studies. Depending on the metal employed, different isomers are formed. The structural properties and differences of all three new compounds are compared to those of previously reported nonfunctionalized methylene-bridged analogues. DFT calculations were conducted to gain a better understanding of the molecular arrangement observed.

Interaction techniques for automating collecting and organizing personal web content (2008)

The growth of the World Wide has led to a dramatic increase in accessible information. Today, people use the for a large variety of activities including travel planning, comparison shopping, entertainment, and research. However, the tools available for collecting, organizing, and sharing content have not kept pace with the rapid growth in information. Today people continue to use bookmarks, email, and printers for managing content. In this thesis, I present a set of semi-automatic interaction techniques for retrieving content from the using the structure of webpages, presentation principles based on layout templates for user-guided organization of content from any number of sources, and a new template-based search paradigm for the that transforms keyword search into a goal-oriented rich visual experience. To demonstrate the efficacy of these ideas I combined them into a working system and evaluated them through a three-month longitudinal user study. Finally, the ideas that I present in this thesis when popularized by an online community would allow average users to build a kind of machine-readable Semantic Web piece by piece as they go about accomplishing their personal tasks.
Elevated Vascular Angiotensin Converting Enzyme in Chronic Two-Kidney, One Clip Hypertension in the Dog (1987)

The possible role of the vascular angiotensin converting enzyme (ACE) in the development of two-kidney, one clip (2-K, 1C) hypertensive dogs was studied in different blood vessels. Vascular ACE activity per mg protein differed in a variety of blood vessels; the activity appeared to vary inversely with the outer diameter of arteries. The systemic blood pressure in mongrel dogs increased after partial occlusion of the left renal artery, and the hypertension lasted for 8 months. Plasma renin activity (PRA) was raised only for the first 4 weeks after the operation and then returned to the original level in the chronic stage of hypertension. Plasma ACE activity did not alter during the experimental period. In contrast, ACE activities in the jejunal, pulmonary and renal arteries, aorta, lung and cerebral cortex, significantly increased in the chronic hypertensive stage (8 months after occlusion). The production of angiotensin II (ANG II) from ANG I was significantly greater in isolated arteries from 8-month hypertensive dogs than in those from normotensive dogs when assessed by the contractile responses to ANG I and ANG II. These results indicate that acceleration by increased vascular ACE activity of the production of ANG II in the vascular wall may contribute to the maintenance of hypertension in the chronic stage of 2-K, 1C hypertensive dogs having normal PRA and plasma ACE activity.
Micro- and Nanoscale Energetic Materials as Effective Heat Energy Sources for Enhanced Gas Generators (2016)

In this study, we systematically investigated the effect of micro- and nanoscale energetic materials in formulations of aluminum microparticles (Al MPs; heat source)/aluminum nanoparticles (Al NPs; heat source)/copper oxide nanoparticles (CuO NPs; oxidizer) on the combustion and gas-generating properties of sodium azide microparticles (NaN3 MPs; gas-generating agent) for potential applications in gas generators. The burn rate of the NaN3 MP/CuO NP composite powder was only ∼0.3 m/s. However, the addition of Al MPs and Al NPs to the NaN3 MP/CuO NP matrix caused the rates to reach ∼1.5 and ∼5.3 m/s, respectively. In addition, the N2 gas volume flow rate generated by the ignition of the NaN3 MP/CuO NP composite powder was only ∼0.6 L/s, which was significantly increased to ∼1.4 and ∼3.9 L/s by adding Al MPs and Al NPs, respectively, to the NaN3 MP/CuO NP composite powder. This suggested that the highly reactive Al MPs and NPs, with the assistance of CuO NPs, were effective heat-generating sources enabling the complete thermal decomposition of NaN3 MPs upon ignition. Al NPs were more effective than Al MPs in the gas generators because of the increased reactivity induced by the reduced particle size. Finally, we successfully demonstrated that a homemade airbag with a specific volume of ∼140 mL could be rapidly and fully inflated by the thermal activation of nanoscale energetic material-added gas-generating agents (i.e., NaN3 MP/Al NP/CuO NP composites) within the standard time of ∼50 ms for airbag inflation.
Flexible Free‐Standing MoO3/Ti3C2Tz MXene Composite Films with High Gravimetric and Volumetric Capacities (2020)

Enhancing both the energy storage and power capabilities of electrochemical capacitors remains a challenge. Herein, Ti<sub>3</sub>C<sub>2</sub>T <i><sub>z</sub></i> MXene is mixed with MoO<sub>3</sub> nanobelts in various mass ratios and the mixture is used to vacuum filter binder free, open, flexible, and free-standing films. The conductive Ti<sub>3</sub>C<sub>2</sub>T <i><sub>z</sub></i> flakes bridge the nanobelts, facilitating electron transfer; the randomly oriented, and interconnected, MoO<sub>3</sub> nanobelts, in turn, prevent the restacking of the Ti<sub>3</sub>C<sub>2</sub>T <i><sub>z</sub></i> nanosheets. Benefitting from these advantages, a MoO<sub>3</sub>/Ti<sub>3</sub>C<sub>2</sub>T <i><sub>z</sub></i> film with a 8:2 mass ratio exhibits high gravimetric/volumetric capacities with good cyclability, namely, 837 C g<sup>-1</sup> and 1836 C cm<sup>-3</sup> at 1 A g<sup>-1</sup> for an ≈ 10 µm thick film; and 767 C g<sup>-1</sup> and 1664 C cm<sup>-3</sup> at 1 A g<sup>-1</sup> for ≈ 50 µm thick film. To further increase the energy density, hybrid capacitors are fabricated with MoO<sub>3</sub>/Ti<sub>3</sub>C<sub>2</sub>T <i><sub>z</sub></i> films as the negative electrodes and nitrogen-doped activated carbon as the positive electrodes. This device delivers maximum gravimetric/volumetric energy densities of 31.2 Wh kg<sup>-1</sup> and 39.2 Wh L<sup>-1</sup>, respectively. The cycling stability of 94.2% retention ratio after 10 000 continuous charge/discharge cycles is also noteworthy. The high energy density achieved in this work can pave the way for practical applications of MXene-containing materials in energy storage devices.
Efficient Self-Ensemble for Semantic Segmentation (2021)

Ensemble of predictions is known to perform better than individual predictions taken separately. However, for tasks that require heavy computational resources, e.g. semantic segmentation, creating an ensemble of learners that needs to be trained separately is hardly tractable. In this work, we propose to leverage the performance boost offered by ensemble methods to enhance the semantic segmentation, while avoiding the traditional heavy training cost of the ensemble. Our self-ensemble approach takes advantage of the multi-scale features set produced by feature pyramid network methods to feed independent decoders, thus creating an ensemble within a single model. Similar to the ensemble, the final prediction is the aggregation of the prediction made by each learner. In contrast to previous works, our model can be trained end-to-end, alleviating the traditional cumbersome multi-stage training of ensembles. Our self-ensemble approach outperforms the current state-of-the-art on the benchmark datasets Pascal Context and COCO-Stuff-10K for semantic segmentation and is competitive on ADE20K and Cityscapes. Code is publicly available at github.com/WalBouss/SenFormer.
Molecular dynamics study of hydrated imogolite : 2. Structure and dynamics of confined water (2008)

The behaviour of water confined in an imogolite nanotube was studied by means of molecular dynamics simulations. The results of the study show an important difference between the interaction of water molecules with the internal and external surfaces of the nanotube. The analysis of the density profiles of confined molecules, of their spatial organisation, of the size of molecular clusters, of the lifetime of H-bonds in the system and of dynamical characteristics of molecules permits us to qualify the external imogolite surface as hydrophobic, whereas the internal surface reveals a hydrophilic character.
A micro-structured ion-implanted magnonic crystal (2013)

We investigate spin-wave propagation in a microstructured magnonic-crystal waveguide fabricated by localized ion implantation. The irradiation caused a periodic variation in the saturation magnetization along the waveguide. As a consequence, the spin-wave transmission spectrum exhibits a set of frequency bands, where spin-wave propagation is suppressed. A weak modification of the saturation magnetization by 7% is sufficient to decrease the spin-wave transmission in the band gaps by a factor of 10. These results evidence the applicability of localized ion implantation for the fabrication of efficient micron- and nano-sized magnonic crystals for magnon spintronic applications.
Body-image dissatisfaction is strongly associated with chronic dysphoria (2013)

Body-image dissatisfaction was a strong predictor of chronic depression characterized by dysphoria. This finding suggests that dysfunctional attitude towards oneself might represent a potentially important target for cognitive therapies and preventive interventions.
Tuning Spin Current Injection at Ferromagnet/Non-Magnet Interfaces by Molecular Design (2020)

There is a growing interest in utilizing the distinctive material properties of organic semiconductors for spintronic applications. Here, we explore injection of pure spin current from Permalloy into a small molecule system based on dinaphtho[2,3-b:2,3-f]thieno[3,2-b]thiophene (DNTT) at ferromagnetic resonance. The unique tunability of organic materials by molecular design allows us to study the impact of interfacial properties on the spin injection efficiency systematically. We show that both, spin injection efficiency at the interface as well as the spin diffusion length can be tuned sensitively by the interfacial molecular structure and side chain substitution of the molecule.
Nitric oxide‐stimulated skeletal muscle capillary flow and glucose uptake in healthy elderly (2006)

One proposed cause of age‐related sarcopenia is a chronic reduction in peripheral blood flow, perhaps reflecting both capillary rarefaction and resistance to capillary recruitment, thereby altering substrate exchange to skeletal muscle tissues. We sought to measure leg glucose uptake (GU) in six healthy elderly in the basal state and during 3 h of nitric oxide (NO)‐stimulated skeletal muscle capillary recruitment. We infused the vasodilator sodium nitroprusside (SNP) into the femoral artery and measured skeletal muscle microvascular volume and flow using contrast‐enhanced ultrasound (CEU) and whole‐leg blood flow using ICG dye dilution. Femoral arterial (A) and venous (V) blood was obtained throughout both periods for measurement of blood glucose levels. Skeletal muscle microvascular recruitment, microvascular flow, and whole‐leg blood flow increased above basal by 60 min of SNP (P&lt;0.05), whereas GU did not significantly elevate until 180 min of SNP (P&lt;0.05). AV glucose increased above basal levels by 60 and 120 min respectively, and remained elevated throughout SNP. No change was measured in A‐V glucose difference or serum insulin concentrations between basal and SNP. These results suggest that exogenous NO administered to healthy elderly increases skeletal muscle capillary flow and later leg glucose uptake in the absence of insulin or exercise stimulation.
Nannocystin A: an Elongation Factor 1 Inhibitor from Myxobacteria with Differential Anti‐Cancer Properties (2015)

Abstract Cultivation of myxobacteria of the Nannocystis genus led to the isolation and structure elucidation of a class of novel cyclic lactone inhibitors of elongation factor 1. Whole genome sequence analysis and annotation enabled identification of the putative biosynthetic cluster and synthesis process. In biological assays the compounds displayed anti‐fungal and cytotoxic activity. Combined genetic and proteomic approaches identified the eukaryotic translation elongation factor 1α (EF‐1α) as the primary target for this compound class. Nannocystin A ( 1 ) displayed differential activity across various cancer cell lines and EEF1A1 expression levels appear to be the main differentiating factor. Biochemical and genetic evidence support an overlapping binding site of 1 with the anti‐cancer compound didemnin B on EF‐1α. This myxobacterial chemotype thus offers an interesting starting point for further investigations of the potential of therapeutics targeting elongation factor 1.
Treating nonhematologic disorders with hematologic stem cells: can this work? (2001)

Two articles in this issue address the utility of hematologic stem cell transplantation for the treatment of nonhematologic inherited diseases. The premise is that genetic deficiencies in nonhematologic tissues can be corrected by allogeneic transplantation of hematopoietic stem cells from healthy
Genotyping SARS-CoV-2 Variants Using Ratiometric Nucleic Acid Barcode Panels (2023)

Designing diagnostic assays to genotype rapidly mutating viruses remains a challenge despite the overall improvements in nucleic acid detection technologies. RT-PCR and next-generation sequencing are unsuitable for genotyping during outbreaks or in point-of-care detection due to their infrastructure requirements and longer turnaround times. We developed a quantum dot barcode multiplexing system to genotype mutated viruses. We designed multiple quantum dot barcodes to target conserved, wildtype, and mutated regions of SARS-CoV-2. We calculated ratios of the signal output from different barcodes that enabled SARS-CoV-2 detection and identified SARS-CoV-2 variant strains from a sample. We detected different sequence types, including conserved genes, nucleotide deletions, and single nucleotide substitutions. Our system detected SARS-CoV-2 patient specimens with 98% sensitivity and 94% specificity across 91 patient samples. Further, we leveraged our barcoding and ratio system to track the emergence of the N501Y SARS-CoV-2 mutation from December 2020 to May 2021 and demonstrated that the more transmissible N501Y mutation started to dominate infections by April 2021. Our barcoding and signal ratio approach can genotype viruses and track the emergence of viral mutations in a single diagnostic test. This technology can be extended to tracking other viruses. Combined with smartphone detection technologies, this assay can be adapted for point-of-care tracking of viral mutations in real time.
Connected e-Bicycle Platoons at Unsignalised Intersections (2021)

This paper presents a concept of an unsignalised intersection control system for connected bicycle platoons. The system is motivated by a real case study of an unsignalised intersection at Tsinghua University, in China, where bicycle jams and accidents frequently occur. The proposed system is assumed to utilise CACC and V2V to coordinate platoon formation and following distance, in order to facilitate and increase traffic filtering at the unsignalised intersection. In this paper, the proposed system is validated using SUMO by emulating four different scenarios, and improvements in bicycle traffic flow and speed, compared to the nominal scenario, are measured. It is seen that the proposed platoon-based system significantly increases intersection flow and speed by 150 % and 764 %, respectively, for west-bound bicycle traffic, in comparison to the nominal scenario. The simulations demonstrate that there exists opportunity in further investigating and developing connected bicycle platoon technology and unsignalised intersection control systems, to make bicycle travel more safe and appealing, and facilitate improvements to transportation options to keep cities moving.
Tracking tumor radiotherapy response in vivo with Cherenkov-excited luminescence ink imaging (2020)

This study demonstrates remote imaging for in vivo detection of radiation-induced tumor microstructural changes by tracking the diffusive spread of injected intratumor UV excited tattoo ink using Cherenkov-excited luminescence imaging (CELI). Micro-liter quantities of luminescent tattoo ink with UV absorption and visible emission were injected at a depth of 2 mm into mouse tumors prior to receiving a high dose treatment of radiation. X-rays from a clinical linear accelerator were used to excite phosphorescent compounds within the tattoo ink through Cherenkov emission. The in vivo phosphorescence was detected using a time-gated intensified CMOS camera immediately after injection, and then again at varying time points after the ink had broken down with the apoptotic tumor cells. Ex vivo tumors were imaged post-mortem using hyperspectral cryo-fluorescence imaging to quantify necrosis and compared to Cherenkov-excited light imaging of diffusive ink spread measured in vivo. Imaging of untreated control mice showed that ink distributions remained constant after four days with less than 3% diffusive spread measured using full width at 20% max. For all mice, in vivo CELI measurements matched within 12% of the values estimated by the high-resolution ex vivo sliced luminescence imaging of the tumors. The tattoo ink spread in treated mice was found to correlate well with the nonperfusion necrotic core volume (R<sup>2</sup> = 0.92) but not well with total tumor volume changes (R<sup>2</sup> = 0.34). In vivo and ex vivo findings indicate that the diffusive spread of the injected tattoo ink can be related to radiation-induced necrosis, independent of total tumor volume change. Tracking the diffusive spread of the ink allows for distinguishing between an increase in tumor size due to new cellular growth and an increase in tumor size due to edema. Furthermore, the imaging resolution of CELI allows for in vivo tracking of subtle microenvironmental changes which occur earlier than tumor shrinkage and this offers the potential for novel, minimally invasive radiotherapy response assay without interrupting a singular clinical workflow.
Plasma assisted evaporation of palladium (1996)

We studied the deposition of palladium on silicon using a high-frequency argon plasma. It is shown that the argon ions are focused and sputtered a biased helicoidal palladium wire. An auxiliary continuous discharge enhancing palladium evaporation rate is obtained for a pressure and bias voltage above 50 m Torr and -200 V respectively, as revealed by optical emission spectroscopy. The growth rate is between 0.5 and 20 Å as deduced from x-ray photoelectron spectroscopy. Scanning tunnelling microscopy studies reveal that growth proceeds through nucleation.
Myeloid ERK5 deficiency suppresses tumor growth by blocking protumor macrophage polarization via STAT3 inhibition (2018)

Owing to the prevalence of tumor-associated macrophages (TAMs) in cancer and their unique influence upon disease progression and malignancy, macrophage-targeted interventions have attracted notable attention in cancer immunotherapy. However, tractable targets to reduce TAM activities remain very few and far between because the signaling mechanisms underpinning protumor macrophage phenotypes are largely unknown. Here, we have investigated the role of the extracellular-regulated protein kinase 5 (ERK5) as a determinant of macrophage polarity. We report that the growth of carcinoma grafts was halted in myeloid ERK5-deficient mice. Coincidentally, targeting ERK5 in macrophages induced a transcriptional switch in favor of proinflammatory mediators. Further molecular analyses demonstrated that activation of the signal transducer and activator of transcription 3 (STAT3) via Tyr705 phosphorylation was impaired in <i>erk5</i>-deleted TAMs. Our study thus suggests that blocking ERK5 constitutes a treatment strategy to reprogram macrophages toward an antitumor state by inhibiting STAT3-induced gene expression.
