ABF2, an ABRE‐binding bZIP factor, is an essential component of glucose signaling and its overexpression affects multiple stress tolerance (2004)

Phytohormone abscisic acid (ABA) regulates stress-responsive gene expression during vegetative growth, which is mediated largely by cis-elements sharing the ACGTGGC consensus. Although many transcription factors are known to bind the elements in vitro, only a few have been demonstrated to have in vivo functions and their specific roles in ABA/stress responses are mostly unknown. Here, we report that ABF2, an ABF subfamily member of bZIP proteins interacting with the ABA-responsive elements, is involved in ABA/stress responses. Its overexpression altered ABA sensitivity, dehydration tolerance, and the expression levels of ABA/stress-regulated genes. Furthermore, ABF2 overexpression promoted glucose-induced inhibition of seedling development, whereas its mutation impaired glucose response. The reduced sugar sensitivity was not observed with mutants of two other ABF family members, ABF3 and ABF4. Instead, these mutants displayed defects in ABA, salt, and dehydration responses, which were not observed with the abf2 mutant. Our data indicate distinct roles of ABF family members: whereas ABF3 and ABF4 play essential roles in ABA/stress responses, ABF2 is required for normal glucose response. We also show that ABF2 overexpression affects multiple stress tolerance.
Polarization-Multiplexed DMT With IM-DD Using 2 &#x00D7; 2 MIMO Processing Based on SOP Estimation and MPBI Elimination (2015)

A simple polarization-multiplexed (PM) discrete multitone (DMT) system with intensity modulation and direct detection (IM-DD) is proposed for short-reach optical communications. Only four photodetectors (PDs) are required at the receiver, and no extra 90° hybrid and balanced detection is necessary. Novel digital signal processing (DSP) algorithms are proposed for state-of-polarization (SOP) estimation and subsequent mixed polarization beat interference (MPBI) elimination. These enable polarization demultiplexing and channel estimation to be implemented by a simple 2 × 2 multiple-input and multiple-output (MIMO) frequency-domain equalizer. The feasibility of the proposed PM-DMT-DD system and the effectiveness of the novel DSP algorithms are investigated via theoretical and simulation studies.
Use of two-dimensional deformable mesh structures for video coding .I. The synthesis problem: mesh-based function approximation and mapping (1996)

This paper explores the use of a deformable mesh (also known as the control grid) structure for motion analysis and synthesis in an image sequence. We focus on the synthesis problem, i.e., how to interpolate an image function given nodal positions and values and how to predict a present image frame from a reference one given nodal displacements between the two images. For this purpose, we review the fundamental theory and numerical techniques that have been developed in the finite element method for function approximation and mapping using a mesh structure. Specifically, we focus on (i) the use of shape functions for node-based function interpolation and mapping; and (ii) the use of regular master elements to simplify numerical calculations involved in dealing with irregular mesh structures. In addition to a general introduction that is applicable to an arbitrary mesh structure, we also present specific results for triangular and quadrilateral mesh structures, which are the most useful two-dimensional (2-D) meshes. Finally, we describe how to apply the above results for motion compensated frame prediction and interpolation. It is shown that the concepts of shape functions and master elements are crucial for developing computationally efficient algorithms for both the analysis and synthesis problems.
Human Activity Recognition Using Inertial Sensors in a Smartphone: An Overview (2019)

The ubiquity of smartphones and the growth of computing resources, such as connectivity, processing, portability, and power of sensing, have greatly changed people's lives. Today, many smartphones contain a variety of powerful sensors, including motion, location, network, and direction sensors. Motion or inertial sensors (e.g., accelerometer), specifically, have been widely used to recognize users' physical activities. This has opened doors for many different and interesting applications in several areas, such as health and transportation. In this perspective, this work provides a comprehensive, state of the art review of the current situation of human activity recognition (HAR) solutions in the context of inertial sensors in smartphones. This article begins by discussing the concepts of human activities along with the complete historical events, focused on smartphones, which shows the evolution of the area in the last two decades. Next, we present a detailed description of the HAR methodology, focusing on the presentation of the steps of HAR solutions in the context of inertial sensors. For each step, we cite the main references that use the best implementation practices suggested by the scientific community. Finally, we present the main results about HAR solutions from the perspective of the inertial sensors embedded in smartphones.

Target Detection Based on Improved Mask Rcnn in Service Robot (2019)

Target detection is one of the core algorithms in robot applications, and the recognition speed has a significant impact on robot's target capture. In this paper, the scene of long-distance and small targets is used as the test scene, and the purpose is to enhance the speed of detection without reducing the accuracy of detection. Consider that the mask branch and excessive full connection layer in the Mask Rcnn network will take up a lot of network detection time, and the feature map extracted by the convolutional neural network has a high dimension, which will occupy a large amount of computational memory. So, in this paper the Mask Rcnn network is improved: remove the mask branch; introduce Light-Head Rcnn into the Mask Rcnn network, increase R-CNN subnet and RoI warping; adjust the proportion of the Anchor in the RPN network. Finally, the improved model is applied to the tensorflow framework. These methods can save computer memory space and improve detection's speed. In the end, the improved Mask Rcnn network has been verified in a service robot platform with Kinect II. The test results show that compared with Faster Rcnn, the improved Mask Rcnn can have a high accuracy of detection; Compared with the original Mask Rcnn, the improved Mask Rcnn network can greatly improve the speed of the algorithm while ensuring the detection accuracy. The detection time is reduced by more than 2 times, which helps to improve the efficiency of the service robot's target capture task.
A practical path loss model for indoor WiFi positioning enhancement (2007)

Positioning within a local area refers to technology whereby each node is self-aware of its position. Based on empirical study, this paper proposes an enhancement to the path loss model in the indoor environment for improved accuracy in the relationship between distance and received signal strength. We further demonstrate the potential of our model for the WiFi positioning system, where the mean errors in the distance estimation are 2.3 m and 2.9 m for line of sight and non line of sight environments, respectively.
Role of Aromatic Side Chains in the Folding and Thermodynamic Stability of Integral Membrane Proteins (2007)

Aromatic residues are frequently found in helical and beta-barrel integral membrane proteins enriched at the membrane-water interface. Although the importance of these residues in membrane protein folding has been rationalized by thermodynamic partition measurements using peptide model systems, their contribution to the stability of bona fide membrane proteins has never been demonstrated. Here, we have investigated the contribution of interfacial aromatic residues to the thermodynamic stability of the beta-barrel outer membrane protein OmpA from Escherichia coli in lipid bilayers by performing extensive mutagenesis and equilibrium folding experiments. Isolated interfacial tryptophanes contribute -2.0 kcal/mol, isolated interfacial tyrosines contribute -2.6 kcal/mol, and isolated interfacial phenylalanines contribute -1.0 kcal/mol to the stability of this protein. These values agree well with the prediction from the Wimley-White interfacial hydrophobicity scale, except for tyrosine residues, which contribute more than has been expected from the peptide models. Double mutant cycle analysis reveals that interactions between aromatic side chains become significant when their centroids are separated by less than 6 A but are nearly insignificant above 7 A. Aromatic-aromatic side chain interactions are on the order of -1.0 to -1.4 kcal/mol and do not appear to depend on the type of aromatic residue. These results suggest that the clustering of aromatic side chains at membrane interfaces provides an additional heretofore not yet recognized driving force for the folding and stability of integral membrane proteins.

Effect of Laser Sintering on Ti–ZrB <sub>2</sub> Mixtures (2011)

Multilayer structures of ZrB 2 containing 30–70 wt% Ti were fabricated using a laser sintering/melting technique. Ti acted as the binding interface for the hard ZrB 2 particles. Structural properties and oxidation behavior of laser‐sintered samples were studied using high‐temperature X‐ray diffraction (HTXRD). HTXRD revealed the formation of boride solid solutions (Zr 0.61 Ti 0.39 B 2 , Zr 0.2 Ti 0.8 B 2 ), Zr 0.3 Ti 0.7 and TiB whiskers as well as several oxide species (Ti 2 ZrO and ZrO x ) during laser sintering process. Laser‐sintered Ti–ZrB 2 mixtures had high relative densities (>92%) and hardness values (up to 11.4 GPa). The reactions enhanced dissolution of ZrB 2 into Ti, governing the final compositions of the mixtures and facilitating the production of high‐density boride solid solutions.

Development of a copper-graphene nanocomposite based transparent coating with antiviral activity against influenza virus (2020)

Abstract Respiratory infections by RNA viruses are one of the major burdens upon global health and economy. Viruses like influenza or coronaviruses can be transmitted through respiratory droplets or contaminated surfaces. An effective antiviral coating can decrease the viability of the virus particles in the outside environment significantly, hence reducing their transmission rate. In this work, we have screened a series of nanoparticles and their composites for antiviral activity using Nano Luciferase based highly sensitive influenza A reporter virus. Using this screening system, we have identified copper-graphene (Cu-Gr) nanocomposite shows strong antiviral activity. Extensive material and biological characterization of the nanocomposite suggested a unique metal oxide embedded graphene sheet architecture that can inactivate the virion particles only within 30 minutes of pre-incubation and subsequently interferes with the entry of these virion particles into the host cell. This ultimately results in reduced viral gene expression, replication and production of progeny virus particles, slowing down the overall pace of progression of infection. Using PVA as a capping agent, we have been able to generate a Cu-Gr nanocomposite based highly transparent coating that retains its original antiviral activity in the solid form.
1,2,3-Triazolo[1,5-a][1,3]benzodiazepine a new heterocyclic system: Synthesis, benzodiazepine receptor binding and theoretical calculations (1996)

This paper reports the synthesis of 1,2,3-triazolo[1,5-a][1,3]benzodiazepines, which represent a new heterocyclic system obtained by 1,3-dipolar cycloaddition reaction of ethyl 2-azidophenylacetate to methylenic compounds activated by a cyano group. The new derivatives were submitted to benzodiazepine receptor binding assays; only the 3-carboethoxy derivative 3c showed moderate receptorial affinity. However, on the basis of biological results, theoretical calculations were made, which suggested useful structural modifications
Proteasome activity restricts lentiviral gene transfer into hematopoietic stem cells and is down-regulated by cytokines that enhance transduction (2006)

The therapeutic potential of hematopoietic stem cell (HSC) gene therapy can be fully exploited only by reaching efficient gene transfer into HSCs without compromising their biologic properties. Although HSCs can be transduced by HIV-derived lentiviral vectors (LVs) in short ex vivo culture, they display low permissivity to the vector, requiring cytokine stimulation to reach high-frequency transduction. Using stringent assays of competitive xenograft repopulation, we show that early-acting cytokines synergistically enhanced human HSC gene transfer by LVs without impairing engraftment and repopulation capacity. Using S-phase suicide assays, we show that transduction enhancement by cytokines was not dependent on cell cycle progression and that LVs can transduce quiescent HSCs. Pharmacologic inhibition of the proteasome during transduction dramatically enhanced HSC gene transfer, allowing the reach of very high levels of vector integration in their progeny in vivo. Thus, LVs are effectively restricted at a postentry step by the activity of this proteolytic complex. Unexpectedly, cytokine stimulation rapidly and substantially down-regulated proteasome activity in hematopoietic progenitors, highlighting one mechanism by which cytokines may enhance permissiveness to LV gene transfer. These findings demonstrate that antiviral responses ultimately mediated by proteasomes strongly limit the efficiency of HSC transduction by LVs and establish improved conditions for HSC-based gene therapy.
Current Interruption at Powers up to 1 GW with Crossed-Field Tubes (1978)

This paper describes the current interruption and voltage holdoff capabilities of a wide range of crossed-field tubes (XFTs). The XFTs investigated have active electrode areas ranging from 96 to 8000 cm2 with mean diameters from 2 to 56 cm. For the larger XFTs, currents up to 10 kA have been interrupted at voltages up to 100 kV, corresponding to a switched power of 1 GW. Experiments have shown the peak interruptible current to vary linearly with tube radius. The mechanism responsible for the limitation may be related to the self-generated magnetic field, but other factors are also shown to play a role.
Textured monocrystalline thin‐film Si cells from the porous silicon (PSI) process (2001)

We have fabricated a textured monocrystalline Si solar cell with a thickness of 15·5 μm and a confirmed efficiency of 12·2% using porous silicon (PSI) for layer transfer. The PSI process avoids photolithography and high-temperature oxidation. The cell has a surface that is textured with randomly positioned inverted pyramids for light trapping. The device does not yet fully exploit the light-trapping capability of this film shape, owing to a small back-surface reflectance. Copyright © 2001 John Wiley & Sons, Ltd.
Iododeoxyuridine chemosensitization of cis-diamminedichloroplatinum(II) in human bladder cancer cells. (1994)

We investigated the effect of iododeoxyuridine (IdUrd) exposure on cis-diamminedichloroplatinum (CDDP) cytotoxicity in the human bladder cancer cell line 647V. Following a 48-h incubation with 2-20 microM IdUrd, a 1-h exposure to 0-120 microM CDDP produced a dose-dependent increase in CDDP cytotoxicity as measured by clonogenic survival. IdUrd exposure of 2, 5, 10, and 20 microM prior to CDDP resulted in dose-modifying factors at 10% survival of 1.2, 1.6, 2.0, and 3.5, respectively. The increase in CDDP cytotoxicity appears to be associated with the level of DNA thymidine replacement in DNA by IdUrd over the range of 13-36%. Atomic absorption spectrophotometric analysis of DNA extracted from 647V cells showed that IdUrd substitution did not affect the total amount of platinum bound to the DNA or the persistence of the bound platinum over a 24-h period post-CDDP exposure versus control cells. IdUrd, unlike thymidine, was found to form two monofunctional adducts with CDDP both in vitro and in vivo. IdUrd was also found to form a mixed bifunctional adduct with deoxyguanosine (dGua) and CDDP in vitro. 1H NMR analysis of purified IdUrd-Pt and IdUrd-Pt-dGua adducts confirmed the identity of these adducts. High pressure liquid chromatography analysis of [3H]IdUrd-labeled 647V DNA digests exposed to CDDP showed the presence of two monofunctional adducts. Unlike the free solution production of adducts in vitro, the predominant adduct formed was not IdUrd-Pt. Results using 125IdUrd-labeled 647V DNA suggests that this adduct is 5-Pt-deoxyuridine. We were not able, however, to detect the presence of the bifunctional adducts IdUrd-Pt-dGua or dUrd-Pt-dGua. This was most likely due to the extremely low proportion of mixed bifunctional adducts produced in vivo. Nonetheless, these results suggest that IdUrd DNA incorporation may enhance CDDP cytotoxicity through the increase of available sites for Pt adduct formation. A Phase I clinical trial of this approach is planned.
Tri-Gate Polycrystalline Silicon Thin-Film Transistors Fabricated by Continuous-Wave Laser Lateral Crystallization with Improved Electron Transport Properties (2012)

Tri-gate channel structures were applied to polycrystalline silicon (poly-Si) thin-film transistors (TFTs) fabricated by continuous-wave (CW) laser lateral crystallization (CLC). We had two objectives in using tri-gate structures in CLC poly-Si TFTs. One was the enhancement of effective electron mobility (µ eff ) by using the tensile strain induced by the CLC process and the lateral-strain-relaxation effect in tri-gate structures. The other was the reduction of µ eff variation caused by increasing the number of surfaces with different crystal orientations by up to a factor of three. By applying tri-gate structures to CLC poly-Si TFTs, both 8% µ eff enhancement and 41% reduction of µ eff variation were achieved at the surface carrier density of 5×10 12 cm -2 . These results are expected to be useful for the device size shrinkage of high-performance poly-Si TFT circuits.

Ta<scp>COLD</scp>1 defines a new regulator of plant height in bread wheat (2018)

Plant height is among the most important agronomic traits that influence crop yield. However, in addition to the Rht-1 alleles, the molecular basis of plant height in bread wheat remains largely unclear. Based on wheat gene expression profiling analysis, we identify a light-regulated gene from bread wheat, designated as TaCOLD1, whose encoding protein is homologous to cold sensor COLD1 in rice. We show that TaCOLD1 protein is localized to the endoplasmic reticulum (ER) and plasma membrane. Phenotypic analyses show that overexpression of a mutated form of TaCOLD1 (M187K) in bread wheat cultivar Kenong199 (Rht-B1b) background resulted in an obvious reduction in plant height. Further, we demonstrate that the hydrophilic loop of TaCOLD1 (residues 178-296) can interact with TaGα-7A (the α subunit of heterotrimeric G protein) protein but not TaGα-1B, and the mutation (M187K) in TaCOLD1 remarkably enhances its interaction with TaGα-7A. Physical interaction analyses show that the C-terminal region of TaGα-7A, which is lacking in the TaGα-1B protein, is necessary for its interaction with TaCOLD1. Intriguingly, the C-terminal region of TaGα-7A is also physically associated with the TaDEP1 protein (an atypical Gγ subunit). Significantly, we discover that TaCOLD1 and mTaCOLD1 (M187K) can interfere with the physical association between TaGα-7A and TaDEP1. Together, this study reveals that TaCOLD1 acts as a novel regulator of plant height through interfering with the formation of heterotrimeric G protein complex in bread wheat and is a valuable target for the engineering of wheat plant architecture.
