Atomic Layer Deposition of CdS Quantum Dots for Solid‐State Quantum Dot Sensitized Solar Cells (2011)

Abstract Functioning quantum dot (QD) sensitized solar cells have been fabricated using the vacuum deposition technique atomic layer deposition (ALD). Utilizing the incubation period of CdS growth by ALD on TiO 2 , we are able to grow QDs of adjustable size which act as sensitizers for solid‐state QD‐sensitized solar cells (ssQDSSC). The size of QDs, studied with transmission electron microscopy (TEM), varied with the number of ALD cycles from 1‐10 nm. Photovoltaic devices with the QDs were fabricated and characterized using a ssQDSSC device architecture with 2,2',7,7'‐tetrakis‐(N,N‐di‐p methoxyphenylamine) 9,9'‐spirobifluorene (spiro‐OMeTAD) as the solid‐state hole conductor. The ALD approach described here can be applied to fabrication of quantum‐confined structures for a variety of applications, including solar electricity and solar fuels. Because ALD provides the ability to deposit many materials in very high aspect ratio substrates, this work introduces a strategy by which material and optical properties of QD sensitizers may be adjusted not only by the size of the particles but also in the future by the composition.
EFFECTS OF VEGETATION HEIGHT ON TURBULENT FLOW STRUCTURE AND SUSPENDED SEDIMENT DEPOSITION (2021)

洪水流による河道内の植生群落における浮遊砂堆積は河積の減少や植生群落の拡大を招くほか，生態系へ影響を及ぼすことも指摘されている．このような植生群落周辺における浮遊砂の輸送・堆積過程を解明し，植生動態を予測することが河川管理上重要である．そこで，本研究では植生周辺の流れ場の特性を左右するパラメータとして植生高さに注目し，実験水路において植生高さを変化させた4通りの植生群落模型内外の流れ場に対してPIV流速計測および浮遊砂堆積実験を実施した．また，流速計測結果と堆積状況との比較を行い，植生高さの変化が群落内部および後流域における乱流構造や浮遊砂堆積に及ぼす影響について検討した．その結果，植生高さによる平均流・乱流構造の変化が植生群落内部および後流域における浮遊砂堆積状況を特徴付けることが確認された．
Nonlinear Deformation Behavior of Bolted Flanges Under Tensile, Torsional and Bending Loads (2010)

This paper investigates the nonlinear deformation behavior of bolted flanges under tensile, torsional and bending loads, using Finite Element Analysis (FEA). Even though the bolted flange may still deform elastically, the variation in contact area due to the external loading will cause nonlinear deformation. In this study, finite element simulation is used for investigating the respective non-linear deformation behavior of a preloaded bolted flange under tensile, torsional and bending loads, and to determine the corresponding stiffness values for each loading.
Case Nortura/Norilia.Improving the utilisation of co-streams in poultry processing (2016)

Industrialised chicken production is far from organic agriculture prinicples. Still of interest is a more sustainable utilisation of by-products, e.g. hydrolysation of feathers for proteins, or extraction of food grade oil from chicken bones. Such approaches were studied in the bioeconomy-project "CYCLE" (2013-2017).

“I Didn’t Know I Looked Angry”: Characterizing Observed Emotion and Reported Affect at Work (2022)

With the growing prevalence of affective computing applications, Automatic Emotion Recognition (AER) technologies have garnered attention in both research and industry settings. Initially limited to speech-based applications, AER technologies now include analysis of facial landmarks to provide predicted probabilities of a common subset of emotions (e.g., anger, happiness) for faces observed in an image or video frame. In this paper, we study the relationship between AER outputs and self-reports of affect employed by prior work, in the context of information work at a technology company. We compare the continuous observed emotion output from an AER tool to discrete reported affect obtained via a one-day combined tool-use and diary study (N = 15). We provide empirical evidence showing that these signals do not completely align, and find that using additional workplace context only improves alignment up to 58.6%. These results suggest affect must be studied in the context it is being expressed, and observed emotion signal should not replace internal reported affect for affective computing applications.
Phylogenetic Analysis of Polyomavirus Simian Virus 40 from Monkeys and Humans Reveals Genetic Variation (2004)

A phylogenetic analysis of 14 complete simian virus 40 (SV40) genomes was conducted in order to determine strain relatedness and the extent of genetic variation. This analysis included infectious isolates recovered between 1960 and 1999 from primary cultures of monkey kidney cells, from contaminated poliovaccines and an adenovirus seed stock, from human malignancies, and from transformed human cells. Maximum-parsimony and distance methods revealed distinct SV40 clades. However, no clear patterns of association between genotype and viral source were apparent. One clade (clade A) is derived from strain 776, the reference strain of SV40. Clade B contains isolates from poliovaccines (strains 777 and Baylor), from monkeys (strains N128, Rh911, and K661), and from human tumors (strains SVCPC and SVMEN). Thus, adaptation is not essential for SV40 survival in humans. The C terminus of the T-antigen (T-ag-C) gene contains the highest proportion of variable sites in the SV40 genome. An analysis based on just the T-ag-C region was highly congruent with the whole-genome analysis; hence, sequencing of just this one region is useful in strain identification. Analysis of an additional 16 strains for which only the T-ag-C gene was sequenced indicated that further SV40 genetic diversity is likely, resulting in a provisional clade (clade C) that currently contains strains associated with human tumors and human strain PML-1. Four other polymorphic regions in the genome were also identified. If these regions were analyzed in conjunction with the T-ag-C region, most of the phylogenetic signal could be captured without complete genome sequencing. This report represents the first whole-genome approach to establishing phylogenetic relatedness among different strains of SV40. It will be important in the future to develop a more complete catalog of SV40 variation in its natural monkey host, to determine if SV40 strains from different clades vary in biological or pathogenic properties, and to identify which SV40 strains are transmissible among humans.
Inhibitory Effects ofSaussurea involucrata. Against Melanogenesis of Mouse-Derived Melanocyte Cells (2007)

Extracts and fractions from the aerial parts of herbal materials of Saussurea involucrata. Kar et Kir ex Maxim (Compositae) were investigated for their whitening activity against mouse-derived immortalized melanocyte cell line. The extract of wild herbs (FS2) possessed a better inhibition (28.2% growth) against melanin cells than that (46.7%) of cultivated herbs (FS1). The whole extracts and middle-polar partitioning fraction show the inhibitory effects, whereas the water-soluble parts show a poor activity in the same assay.
Reducing Clutter on Tabletop Groupware Systems with Tangible Drawers (2006)

Simultaneously presenting multiple users ’ data on a single, shared display, such as an interactive tabletop, often results in visual clutter. One strategy to reduce clutter on horizontal surfaces in the physical world is to store objects in drawers. Items in drawers are hidden from view but are accessible when needed. Inspired by analogies with traditional desks and tables, we have developed tangible drawer mechanisms to augment a projected multi-user tabletop display. The drawers serve as dedicated input mechanisms to access, scroll through, and hide personal data. We describe our implementation and interaction techniques, and then report results from an informal pilot study.
Tumor Associated Ascites Inhibits CD1d-Mediated NKT cell Activation (88.18) (2009)

Abstract Natural killer T (NKT) cells recognize lipid antigen presented by CD1d molecules. It has been shown that NKT cells can both directly and indirectly mediate anti-tumor immunity. However, it is thought that the anti-tumor effects mediated by these cells are being hampered because the number and function of NKT cells are reduced in cancer patients. In addition, it has been shown that tumor associated glycolipids are frequently shed into the tumor microenvironment, which can mediate immunosuppressive activity. In these studies we examined antigen presentation by CD1d following treatment with ascites from ovarian cancer patients. It was found that pretreatment with ascites inhibited the ability of CD1d expressing cells to activate NKT cells in a dose-dependent manner. We found that this inhibition does not require antigen processing, as canonical (Vα14+) and noncanonical NKT cells, which do not require trafficking through endocytic compartments, were both inhibited. Also, ascites treatment of artificial Antigen Presenting Cells (aAPC) preloaded with α-GalCer, abrogated their ability to present antigen to NKT cells, which further suggests that the inhibition is antigen processing independent. In addition, our data demonstrate that treatment antigen presenting cells with ascites does not inhibit activation of classical CD8+ T cells. Together, these data suggest that glycolipid shedding in ascites may be a mechanism of immune evasion specifically utilized used by cancers to inhibit CD1d- mediated activation of NKT cells.

Two-Step Chemical Vapor Deposition-Synthesized Lead-Free All-Inorganic Cs3Sb2Br9 Perovskite Microplates for Optoelectronic Applications (2021)

Lead-based halide perovskites (APbX<sub>3</sub>, where A = organic or inorganic cation, X = Cl, Br, I) are suitable materials for many optoelectronic devices due to their many attractive properties. However, the concern of lead toxicity and the poor ambient and operational stability of the organic cation group greatly limit their practical utilization. Therefore, there has recently been great interest in lead-free, environment-friendly all-inorganic halide perovskites (IHPs). Sb and Sn are common species suggested to replace Pb for Pb-free IHPs. However, the large difference in the melting points of the precursor materials (e.g., CsBr and SbBr<sub>3</sub> precursors for Cs<sub>3</sub>Sb<sub>2</sub>Br<sub>9</sub>) makes the chemical vapor deposition (CVD) growth of high-quality Pb-free IHPs a very challenging task. In this work, we developed a two-step CVD method to overcome this challenge and successfully synthesized Pb-free Cs<sub>3</sub>Sb<sub>2</sub>Br<sub>9</sub> perovskite microplates. Cs<sub>3</sub>Sb<sub>2</sub>Br<sub>9</sub> microplates ∼25 μm in size with the exciton absorption peak at ∼2.8 eV and a band gap of ∼2.85 eV were obtained. The microplates have a smooth hexagonal morphology and show a large Stokes shift of ∼450 meV and exciton binding energy of ∼200 meV. To demonstrate the applications of these microplates in optoelectronics, simple photoconductive devices were fabricated. These photodetectors exhibit a current on/off ratio of 2.36 × 10<sup>2</sup>, a responsivity of 36.9 mA/W, and a detectivity of 1.0 × 10<sup>10</sup> Jones with a fast response of rise and decay time of 61.5 and 24 ms, respectively, upon 450 nm photon irradiation. Finally, the Cs<sub>3</sub>Sb<sub>2</sub>Br<sub>9</sub> microplates also show good stability in ambient air without encapsulation. These results demonstrate that the 2-step CVD process is an effective approach to synthesize high-quality all-inorganic lead-free Cs<sub>3</sub>Sb<sub>2</sub>Br<sub>9</sub> perovskite microplates that have the potential for future high-performance optoelectronic device applications.

Investigations on an integrated conducting nanoparticle–liquid crystal elastomer layer (2007)

A process is outlined in which an existing liquid crystal elastomer (LCE) can be reprocessed from an insulating network to create an effectively conducting network. This is performed through the LCE volume expansion in a suitable solution containing conducting nanoparticles. Subsequent volume compression results in the formation of a conducting layer at the LCE surfaces. The swelling behaviour of the LCE is illustrated. Elemental composition analysis and electron imagining techniques show that the conducting layer is composed of conducting nanoparticles and LCE material. It was found that the integrated layer thickness and resistivity can be controlled through the LCE surface expansion ratio and conducting nanoparticle concentration, respectively.
2D Monoelemental Germanene Quantum Dots: Synthesis as Robust Photothermal Agents for Photonic Cancer Nanomedicine (2019)

As a new family member of the emerging two-dimensional (2D) monoelemental materials (Xenes), germanene has shown promising advantages over the prototypical 2D Xenes, such as black phosphorus (BP) and graphene. However, efficient manufacture of novel germanene nanostructures is still a challenge. Herein, a simple top-down approach for the liquid-exfoliation of ultra-small germanene quantum dots (GeQDs) is presented. The prepared GeQDs possess an average lateral size of about 4.5 nm and thickness of about 2.2 nm. The functionalized GeQDs were demonstrated to be robust photothermal agents (PTAs) with outstanding photothermal conversion efficacy (higher than those of graphene and BPQDs), superior stability, and excellent biocompatibility. As a proof-of-principle, 2D GeQDs-based PTAs were used in fluorescence/photoacoustic/photothermal-imaging-guided hyperpyrexia ablation of tumors. This work could expand the application of 2D germanene to the field of photonic cancer nanomedicine.

The Role of Stem Cell Factor and Granulocyte-Colony Stimulating Factor in Brain Repair during Chronic Stroke (2009)

Chronic stroke is a highly important but under-investigated scientific problem in neurologic research. We have reported earlier that stem cell factor (SCF) in combination with granulocyte-colony stimulating factor (G-CSF) treatment during chronic stroke improves functional outcomes. Here we have determined the contribution of bone marrow-derived cells in angiogenesis and neurogenesis, which are enhanced by SCF+G-CSF treatment during chronic stroke. Using bone marrow tracking, flow cytometry, 2-photon live brain imaging, and immunohistochemistry, we observed that the levels of circulating bone marrow stem cells (BMSCs) (CD34+/c-kit+) were significantly increased by SCF+G-CSF treatment. In addition, live brain imaging revealed that numerous bone marrow-derived cells migrate into the brain parenchyma in the treated mice. We also found that bone marrow-derived cells, bone marrow-derived endothelial cells, vascular density, and bone marrow-derived neurons were significantly augmented by SCF+G-CSF. It is interesting that, in addition to the increase in bone marrow-derived endothelial cells, the number of bone marrow-derived pericytes was reduced after SCF+G-CSF treatment during chronic stroke. These data suggest that SCF+G-CSF treatment can enhance repair of brain damage during chronic stroke by mobilizing BMSCs, and promoting the contribution of bone marrow-derived cells to angiogenesis and neurogenesis.
Uniform Growth of High-Quality Oxide Thin Films on Graphene Using a CdSe Quantum Dot Array Seeding Layer (2014)

Graphene displays outstanding properties as an electrode and a semiconducting channel material for transistors; however, the weak interfacial bond between graphene and an inorganic oxide material-based insulator presents a major constraint on these applications. Here, we report a new approach to improving the interface between the two materials using a CdSe quantum dot (QD)-based seeding layer in an inorganic material-graphene junction. CdSe QDs were electrochemically grown on graphene without degrading the properties of the graphene layer. The graphene structure was then used as the electrode in an oxide semiconductor by depositing a zinc oxide thin film onto the graphene coated with a QD seed layer (QD/G). The zinc oxide film adhered strongly to the graphene layer and provided a low contact resistance. A high-k dielectric layer in the form of an HfO2 film, which is an essential element in the fabrication of high-performance graphene-based field effect transistors, was also uniformly formed on the QD/G sheet using atomic layer deposition. The resulting transistors provided a relatively good performance, yielding hole and electron mobilities of 2600 and 2000 cm(2)/V·s.
Development of a high throughput LDPC codec with 1Gb/s and OFDM transmission system utilizing MBD (2009)

Low-density parity-check (LDPC) codes, which are among the most powerful error correcting codes, can achieve performance close to the Shannon limit. It is difficult to evaluate the performance of LDPC codes by software simulation only, because it takes much time and labor. To solve this problem, we have developed the design environment for designing and evaluating LDPC codes on hardware.
Modeling the Cost of Flexibility in Communication Networks (2021)

Communication networks are evolving towards a more adaptive and reconfigurable nature due to the evergrowing demands they face. A framework for measuring network flexibility has been proposed recently, but the cost of rendering communication networks more flexible has not yet been mathematically modeled. As new technologies such as software-defined networking (SDN), network function virtualization (NFV), or network virtualization (NV) emerge to provide network flexibility, a way to estimate and compare the cost of different implementation options is needed. In this paper, we present a comprehensive model of the cost of a flexible network that takes into account its transient and stationary phases. This allows network researchers and operators to not only qualitatively argue about their new flexible network solutions, but also to analyze their cost for the first time in a quantitative way.
Linear multi view reconstruction and camera recovery (2002)

This paper presents a linear algorithm for the simultaneous computation of 3D points and camera positions from multiple perspective views, based on having four points on a reference plane visible in all views. The reconstruction and camera recovery is achieved, in a single step, by finding the null-space of a matrix using singular value decomposition. Unlike factorization algorithms, the presented algorithm does not require all points to be visible in all views. By simultaneously reconstructing points and views the numerically stabilizing effect of having wide spread cameras with large mutual baselines is exploited. Experimental results are presented for both finite and infinite reference planes. An especially interesting application of this method is the reconstruction of architectural scenes with the reference plane taken as the plane at infinity which is visible via three orthogonal vanishing points. This is demonstrated by reconstructing the outside and inside (courtyard) of a building on the basis of 35 views in one single SVD.
Data from Radiotherapy Induces Innate Immune Responses in Patients Treated for Prostate Cancers (2023)

&lt;div&gt;AbstractPurpose:&lt;p&gt;Radiotherapy is a curative therapeutic modality used to treat cancers as a single agent or in combination with surgery and chemotherapy. Advanced radiotherapy technologies enable treatment with large fractions and highly conformal radiation doses to effect free-radical damage to cellular DNA leading to cell-cycle arrest, cell death, and innate immune response (IIR) stimulation.&lt;/p&gt;Experimental Design:&lt;p&gt;To understand systemic clinical responses after radiation exposure, proteomic and metabolomic analyses were performed on plasma obtained from patients with cancer at intervals after prostate stereotactic body radiotherapy. Pathway and multivariate analyses were used to delineate molecular alterations following radiotherapy and its correlation with clinical outcomes.&lt;/p&gt;Results:&lt;p&gt;DNA damage response increased within the first hour after treatment and returned to baseline by 1 month. IIR signaling also increased within 1 hour of treatment but persisted for up to 3 months thereafter. Furthermore, robust IIR and metabolite elevations, consistent with an early proinflammatory M1-mediated innate immune activation, were observed in patients in remission, whereas patients experiencing prostate serum antigen–determined disease progression demonstrated less robust immune responses and M2-mediated metabolite elevations.&lt;/p&gt;Conclusions:&lt;p&gt;To our knowledge, these data are the first report of longitudinal proteomic and metabolomic molecular responses in patients after radiotherapy for cancers. The data supports innate immune activation as a critical clinical response of patients receiving radiotherapy for prostate cancer. Furthermore, we propose that the observed IIR may be generalized to the treatment of other cancer types, potentially informing multidisciplinary therapeutic strategies for cancer treatment.&lt;/p&gt;&lt;/div&gt;
<i>Phomopsis vaccinii</i>: the Main Pathogen Causing Market Diseases in Kiwifruit (2015)

Imported kiwifruit affected by soft rot on Shanghai fruit market was selected for pathogen isolation and identification. The pathogenicity of different strains was compared. Morphological detection was combined with molecular tools to identify the main pathogenic strains as well as their biological characteristics. The results showed that Phomopsis was the main pathogen causing soft rot, and Phomopsis vaccinii (P. vaccinii) had the highest pathogenicity. Soft rot in kiwifruit caused by P. vaccinii was effectively inhibited under 5°C. This article is a first report of the pathogens causing soft rot in kiwifruit in Chinese market. Valuable experimental evidence is provided for the study on the pathogens carried by kiwifruit imported from New Zealand and on the occurrence of soft rot on the market.
A New Type of Optical Antenna: Plasmonics Nanoshell Bowtie Antenna with Dielectric Hole (2010)

We first investigate plasmonic nanoshell bowtie nanoantenna with dielectric hole that interact with incident plane wave of transverse-magnetic polarization by use of the finite element method. The influence of the dielectric hole in nanoshell on the antenna field enhancement and spectral response is discussed. Results show that the proposed plasmonic nanoshell bowtie antenna can confine the field in a volume well below the diffraction limit and exhibit tunable surface plasmon resonances in a wider range of wavelength that are not observed for the conventional solid-gold case with the same volume. This offers a new possibility to further optimize the performance of optical nanoantenna.
