Novel Temporal Error Concealment Algorithm Based on Residue Restoration (2009)

The temporal error concealment is an important post processing technique to combat transmission errors for video communication, which is usually achieved by motion vector estimation and temporal replacement using temporal correlation existing in video data. However, the quality of concealed video is not satisfactional due to missing residual data lost in transmission. In this paper, a novel temporal error concealment algorithm based on residual estimation is proposed. The motion compensated temporal concealment is used to recover the most damaged macroblock firstly. Then the residual is estimated by the boundary residual of current macroblock and predictive macroblock. Lastly the estimated residual is added to the restored macroblock to achieve more accurate video quality. Experimental results show that the proposed algorithm can efficiently improve the video equality (by 2-4 dB) compared with motion compensation error concealment algorithm (MCECA).
Engineering of <i>Ralstonia eutropha</i> for Production of Poly(3-hydroxybutyrate-<i>co</i>-3-hydroxyhexanoate) from Fructose and Solid-State Properties of the Copolymer (2002)

Recombinant Ralstonia eutropha capable of producing poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) copolymer [P(3HB-co-3HHx)] from fructose was engineered by introduction of genes for crotonyl-CoA reductase (CCR) from Streptomyces cinnamonensis (ccrSc) and for PHA synthase and (R)-specific enoyl-CoA hydratase from Aeromonas caviae (phaC-JAc). In this recombinant strain, C6-acyl-CoA intermediates were provided via beta-ketothiolase-mediated elongation of butyryl-CoA, which was generated from crotonyl-CoA by the function of CCR. The recombinant strain could accumulate the copolyester up to 48 wt % of dry cell weight with 1.5 mol % of 3HHx fraction from fructose, when the expression of ccrSc under the control of the PBAD promoter was induced with 0.01% L-arabinose. The absence of L-arabinose or the deletion of ccrSc from the plasmid resulted in accumulation of poly(3-hydroxybutyrate) homopolymer, indicating the critical role of CCR in the formation of the 3-hydroxyhexanoate unit. Higher CCR activity obtained by the addition of a larger amount of L-arabinose did not affect the composition but reduced the intracellular content of the copolyester. The P(3HB-co-1.5 mol % 3HHx) copolyester produced from fructose by the recombinant R. eutropha showed relatively lower melting temperatures (150 degrees C and 161 degrees C) and lower crystallinity (48 +/- 5%) compared to those (175 degrees C and 60 +/- 5%) of P(3HB) homopolymer. It has been found that the incorporation of a small amount (1.5 mol %) of 3HHx units into P(3HB) sequences leads to a remarkable change in the solid-state properties of P(3HB) crystals. The present study demonstrates the potential of the engineered pathway for the production of copolyesters having favorable characteristics from inexpensive carbon resources.
Improved Oxide Ion Conductivity in La<sub>0.8</sub>Sr<sub>0.2</sub>Ga<sub>0.8</sub>Mg<sub>0.2</sub>O<sub>3</sub> by Doping Co (1999)

The effects of doping Co for the Ga site on the oxide ion conductivity of La0.8Sr0.2Ga0.8Mg0.2O3 have been investigated in detail. It was found that doping Co is effective for enhancing the oxide ion conductivity. In particular, a significant increase in conductivity in the low-temperature range was observed. The electrical conductivity was monotonically increased; however, the transport number for the oxide ion decreased with an increasing amount of Co. Considering the transport number and ion transport number, an optimized amount for the Co doping seems to exist at 8.5 mol % for Ga site. The theoretical electromotive forces were exhibited on H2−O2 gas cell utilizing the optimized composition of La0.8Sr0.2Ga0.8Mg0.115Co0.085O3. The diffusion characteristics of the oxide ion in La0.8Sr0.2Ga0.8Mg0.115Co0.085O3 were also investigated by using the 18O tracer method. Since the diffusion coefficient measured by the 18O tracer method was similar to that estimated by the electrical conductivity, the conduction of La0.8Sr0.2Ga0.8Mg0.115Co0.085O3 is concluded to be almost ionic. On the other hand, an oxygen permeation measurement suggests that the oxide ion conductivity increased linearly with an increasing amount of Co. Therefore, specimens with Co content higher than 10 mol % can be considered as a superior mixed oxide ion and hole conductor. The UV−vis spectra suggests that the valence number of doped Co was changed from +3 to +2 with decreasing oxygen partial pressure; the origin of hole conduction can thus be assigned to the formation of Co3+. Since the amount of dopant in the Ga site was compensated with Mg2+, the amount of oxygen deficiency was decreased by doping Co. Therefore, it is likely that the improved oxide ion conductivity observed by doping with Co is brought about by the enhanced mobility of oxide ion.

Multimodal Sentiment Analysis: Addressing Key Issues and Setting Up the Baselines (2018)

We compile baselines, along with dataset split, for multimodal sentiment analysis. In this paper, we explore three different deep-learning-based architectures for multimodal sentiment classification, each improving upon the previous. Further, we evaluate these architectures with multiple datasets with fixed train/test partition. We also discuss some major issues, frequently ignored in multimodal sentiment analysis research, e.g., the role of speaker-exclusive models, the importance of different modalities, and generalizability. This framework illustrates the different facets of analysis to be considered while performing multimodal sentiment analysis and, hence, serves as a new benchmark for future research in this emerging field.
Opposite Effects of Daylength and Temperature on Flowering and Summer Dormancy of Poa bulbosa (2006)

Variation in the flowering capacity of ecotypes differing in drought tolerance was interpreted as the result of balanced opposite effects of daylength and temperature on the flowering and dormancy processes.
Experimental study of PSPMT (2000)

A pulse light source, guided through an optical fiber of 0.15mm, was used to test PSPMT R2486. The following results are obtained: (1) position linearity: absolute non-linearity of 0.63mm and differential non-linearity of 0.1mm; (2) gain non-linearity: ≤30%; (3) space resolution: 0.4mm.
Straight Skeletons of Three-Dimensional Polyhedra (2008)

This paper studies the straight skeleton of polyhedra in three dimensions. We first address voxel-based polyhedra (polycubes), formed as the union of a collection of cubical (axis-aligned) voxels. We analyze the ways in which the skeleton may intersect each voxel of the polyhedron, and show that the skeleton may be constructed by a simple voxel-sweeping algorithm taking constant time per voxel. In addition, we describe a more complex algorithm for straight skeletons of voxel-based polyhedra, which takes time proportional to the area of the surfaces of the straight skeleton rather than the volume of the polyhedron. We also consider more general polyhedra with axis-parallel edges and faces, and show that any n-vertex polyhedron of this type has a straight skeleton with O(n^2) features. We provide algorithms for constructing the straight skeleton, with running time O(min(n^2 log n, k log^{O(1)} n)) where k is the output complexity. Next, we discuss the straight skeleton of a general nonconvex polyhedron. We show that it has an ambiguity issue, and suggest a consistent method to resolve it. We prove that the straight skeleton of a general polyhedron has a superquadratic complexity in the worst case. Finally, we report on an implementation of a simple algorithm for the general case.
Tourist experience development: Designed attributes, perceived experiences and customer value (2012)

Contemporary consumers are increasingly seeking more experiences than products, and Pine and Gilmore (1998) have set out a vision for this new economic era - the experience economy- in which consumers look for affective memories, sensation and symbolism that combine to create a holistic and long-lasting personal experience. Within the tourism literature, it is widely accepted that tourism 'primarily sells a "staged" experience ... tourism's central productive activity [is] the creation of the touristic experience' (Sternberg, 1997. p. 952, 954). Tourism Australia, for example, has identified seven types of experiences that have the most potential to encourage international travellers to visit Australia and has based its international marketing on these, such as Aboriginal Australia, Outback Australia, or Food and Wine (Tourism Australia, 2011). Businesses as diverse as wine lasting centres, urban precincts and museums are rethinking their offerings to enl1ance the customer experience (Scott, Laws, & Boksberger, 2009). Hence, there is a need for managers of tourism businesses to consider how to design or develop their experiences to improve or increase customer value (CV). [extract]
A new scanning tunneling microscope reactor used for high-pressure and high-temperature catalysis studies (2008)

We present the design and performance of a homebuilt high-pressure and high-temperature reactor equipped with a high-resolution scanning tunneling microscope (STM) for catalytic studies. In this design, the STM body, sample, and tip are placed in a small high pressure reactor ( approximately 19 cm(3)) located within an ultrahigh vacuum (UHV) chamber. A sealable port on the wall of the reactor separates the high pressure environment in the reactor from the vacuum environment of the STM chamber and permits sample transfer and tip change in UHV. A combination of a sample transfer arm, wobble stick, and sample load-lock system allows fast transfer of samples and tips between the preparation chamber, high pressure reactor, and ambient environment. This STM reactor can work as a batch or flowing reactor at a pressure range of 10(-13) to several bars and a temperature range of 300-700 K. Experiments performed on two samples both in vacuum and in high pressure conditions demonstrate the capability of in situ investigations of heterogeneous catalysis and surface chemistry at atomic resolution at a wide pressure range from UHV to a pressure higher than 1 atm.
All-polymer photonic sensing platform based on whispering-gallery mode microgoblet lasers (2015)

We present an all-polymer photonic sensing platform based on whispering-gallery mode microgoblet lasers integrated into a microfluidic chip. The chip is entirely made from polymers, enabling the use of the devices as low-cost disposables. The microgoblet cavities feature quality factors exceeding 10(5) and are fabricated from poly(methyl methacrylate) (PMMA) using spin-coating, mask-based optical lithography, wet chemical etching, and thermal reflow. In contrast to silica-based microtoroid resonators, this approach replaces technically demanding vacuum-based dry etching and serial laser-based reflow techniques by solution-based processing and parallel thermal reflow. This enables scaling to large-area substrates, and hence significantly reduces device costs. Moreover, the resonators can be fabricated on arbitrary substrate materials, e.g., on transparent and flexible polymer foils. Doping the microgoblets with the organic dye pyrromethene 597 transforms the passive resonators into lasers. Devices have lasing thresholds below 0.6 nJ per pulse and can be efficiently pumped via free-space optics using a compact and low-cost green laser diode. We demonstrate that arrays of microgoblet lasers can be readily integrated into a state-of-the-art microfluidic chip replicated via injection moulding. In a proof-of-principle experiment, we show the viability of the lab-on-a-chip via refractometric sensing, demonstrating a bulk refractive index sensitivity (BRIS) of 10.56 nm per refractive index unit.
Group VIII Coordination Chemistry of a Pincer-Type Bis(8-quinolinyl)amido Ligand (2008)

This paper provides an entry point to the coordination chemistry of the group VIII chemistry of the bis(8-quinolinyl)amine (BQA) ligand. In this context, mono- and disubstituted BQA complexes of iron, ruthenium, and osmium are described. For example, the low-spin bis-ligated Fe(III) complex [Fe(BQA)(2)][BPh(4)] has been prepared via amine addition to FeCl(3) in the presence of a base and NaBPh(4). Complexes featuring a single BQA ligand are more readily prepared for Ru and Os. Auxiliary ligands featuring a single BQA ligand, along with two other L-type donor ligands, allow for a variety of ligand types to occupy a sixth coordination site. Representative examples include the halide and pseudohalide complexes trans-(BQA)MX(PPh(3))(2) (M = Ru, Os; X = Cl, Br, N(3), OTf), as well as the hydride and alkyl complexes trans-(BQA)RuH(PMe(3))(2) and trans-(BQA)RuMe(PMe(3))(2). Electrochemical studies are discussed that help to contextualize the BQA ligand with respect to its neutral counterpart 2,2',2''-terpyridine (terpy) in terms of electron-releasing character. Bidentate ligands have been explored in conjunction with the BQA ligand. Thus, the bidentate, monoanionic aryl(8-quinolinyl)amido ligand 3,5-(CF(3))(2)-(C(6)H(3))QA has been installed onto the (BQA)Ru platform to provide (BQA)Ru(3,5-(CF(3))(2)-(C(6)H(3))QA)(PPh(3)). A bis(phosphino)borate ligand stabilizes the five-coordinate complex [Ph(2)B(CH(2)PPh(2))(2)]Ru(BQA). Finally, access to dinitrogen complexes of the types [(BQA)Ru(N(2))(PPh(3))(2)][PF(6)], [(BQA)Ru(N(2))(PMe(3))(2)][PF(6)], and [(BQA)Os(N(2))(PPh(3))(2)][PF(6)] is provided by exposure of the sixth coordination site under a N(2) atmosphere.

Factors Affecting the Properties of Heat Insulating Mica Bricks Part II (1963)

The factors likely to affect the end properties and particularly the fired strength of heat insulating mica bricks made by the extrusion process were studied. As compared to the soft-mud process, extrusion improved the strength considerably and the best results were obtained using Rajhara fire day. Soaking time rather than the firing temperature was found to be more effective in increasing the strength of the bricks.
A survey of codes for partial response channels (1991)

The author gives a brief summary of partial response systems as they apply to magnetic recording systems. A summary of coding techniques useful for partial response systems is given. Most magnetic recording systems in use today use peak detection and thus employ some type of modulation code to control the peak shift. Currently, there is a great deal of interest in partial response systems. Codes will also be used with these systems, but they could be very different in nature from the modulation codes used today. Several types of codes for use with partial response equalization are surveyed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A high-sensitive ultra-thin MEMS capacitive pressure sensor (2011)

This paper reports an ultra-thin MEMS capacitive pressure sensor with high pressure sensitivity of better than 150aF/Pa, and small die size of 1.0mm × 1.0mm × 60µm. It is able to detect ambient pressure change with a resolution of 0.025% in a pressure range +/−3.5KPa. This capacitive pressure sensor decouples the pressure sensing from its capacitance sensing by using a hermetically sealed capacitor that is electrically isolated but mechanically coupled with a pressure sensing diaphragm such that a large dynamic range and high pressure sensitivity can be readily achieved. Because the capacitor is hermetically sealed in a cavity, this capacitive pressure sensor is also immune to measurement media and EMI (Electromagnetic Interference) effects.
Down-regulation of SFRP1 as a putative tumor suppressor gene can contribute to human hepatocellular carcinoma (2007)

Our data suggested that the down-regulation of SFRP1 as a candidate tumor suppressor gene, triggered by the epigenetic and/or genetic events, could contribute to the oncogenesis of HCC.
IGF binding protein-3 regulates hematopoietic stem cell and endothelial precursor cell function during vascular development (2007)

We asked whether the hypoxia-regulated factor, insulin-like growth factor binding protein-3 (IGFBP3), could modulate stem cell factor receptor (c-kit+), stem cell antigen-1 (sca-1+), hematopoietic stem cell (HSC), or CD34+ endothelial precursor cell (EPC) function. Exposure of CD34+ EPCs to IGFBP3 resulted in rapid differentiation into endothelial cells and dose-dependent increases in cell migration and capillary tube formation. IGFBP3-expressing plasmid was injected into the vitreous of neonatal mice undergoing the oxygen-induced retinopathy (OIR) model. In separate studies, GFP-expressing HSCs were transfected with IGFBP3 plasmid and injected into the vitreous of OIR mice. Administering either IGFBP3 plasmid alone or HSCs transfected with the plasmid resulted in a similar reduction in areas of vasoobliteration, protection of the developing vasculature from hyperoxia-induced regression, and reduction in preretinal neovascularization compared to control plasmid or HSCs transfected with control plasmid. In conclusion, IGFBP3 mediates EPC migration, differentiation, and capillary formation in vitro. Targeted expression of IGFBP3 protects the vasculature from damage and promotes proper vascular repair after hyperoxic insult in the OIR model. IGFBP3 expression may represent a physiological adaptation to ischemia and potentially a therapeutic target for treatment of ischemic conditions.
The role of monocytes in thrombotic disorders (2009)

Although, the main physiological role of monocytes is attributed to innate immunity (that is, phagocytosis) and the development of tissue macrophages and dendritic cells, the pathophysiological role of these goes far behind these (simplistic) limits. Indeed, monocytes constitute a major source of blood tissue factor, a key element of the extrinsic coagulation cascade. Monocytes actively bind to platelets, thus forming very prothrombotic monocyte-platelet aggregates. Additionally, these cells link inflammation and the procoagulant state observed in various prothrombotic conditions. However, monocytes are also crucial for successful thrombus recanalisation. In this article, we review the available data on potential mechanisms that link monocytes with thrombosis-related processes.
Modular Construction of 2-Substituted Benzo[b]furans from 1,2-Dichlorovinyl Ethers (2009)

(E)-1,2-Dichlorovinyl ethers and amides are easily accessible from trichloroethylene via nucleophilic addition across in situ synthesized dichloroacetylene. A one-pot, sequential Suzuki-Miyaura coupling/intramolecular direct arylation between dichlorovinyl ethers and organoboronic acids provides easy access to a variety of benzofurans in only two steps from inexpensive commercially available compounds. The method is extendable to the preparation of indoles from the analogous dichlorovinyl amides.
Theorien, Modelle, Märkte (1999)

In dem Lehrbuch Makroökonomie I entwickelten wir die zum Verständnis einer modernen Volkswirtschaft erforderlichen makroökonomischen Definitionen, Kategorien und Kreislaufzusammenhänge. Diese Betrachtungsweise nannten wir „ex - post“, d.h. wir konzentrierten uns auf die möglichst präzise und vollständige Erfassung vergangener, ökonomisch relevanter, empirischer Tatbestände.

Doch vermag die ex - post Betrachtung keine Antworten auf Fragen zu geben wie die folgenden:
Prospects for <i>n</i>-type doping of (Al<i>x</i>Ga1−<i>x</i>)2O3 alloys (2020)

We systematically explore the properties of group-IV (C, Si, Ge, and Sn) and transition metal (Hf, Zr, and Ta) dopants substituting on the cation site in (AlxGa1−x)2O3 (AlGO) alloys using first-principles calculations with a hybrid functional. In Ga2O3, each of these dopants acts as a shallow donor. In Al2O3, they are deep defects characterized by the formation of either DX centers or positive-U (+/0) levels. Combining our calculations of dopant charge-state transition levels with information of the AlGO alloy band structure, we estimate the critical Al composition at which each dopant transitions from being a shallow to a deep donor. We identify Si to be the most efficient dopant to achieve n-type conductivity in high Al-content AlGO alloys, acting as a shallow donor over the entire predicted stability range for AlGO solid solution alloys.
Homography based parallel volume intersection: toward real-time volume reconstruction using active cameras (2002)

Silhouette volume intersection is one of the most popular ideas for reconstructing the 3D volume of an object from multi-viewpoint silhouette images. This paper presents a novel parallel volume intersection method based on plane-to-plane homography for real-time 3D volume reconstruction using active cameras. This paper mainly focuses on the acceleration of back-projection from silhouette images to 3D space without using any sophisticated software technique, such as octree volume representation, or look-up table based projection acceleration. Also this paper presents a parallel intersection method of projected silhouette images. From the preliminary experimental results we estimate near frame-rate volume reconstruction for a life-sized mannequin can be achieved at 3 cm spatial resolution on our PC cluster system.
