A Real-Time 2D to 3D Video Conversion Algorithm Based on Image Shear Transformation (2015)

3D movies can bring immersive feelings to people. They are popular nowadays. At present, numbers of 3D movies are produced each year, but these can not satisfy the growing demands. The productions of 3D movies are complex, and which cost high and takes a long time. 2D to 3D conversion technologies can convert the existing 2D video to 3D video quickly and effectively, which could reduce the difficulty and cost. Therefore, these technologies can alleviate the problem of insufficient 3D videos to a great degree. A real-time 2D to 3D algorithm based on image shear transformation is presented in this paper. According to the shear transformation factor, each frame in the 2D video is converted along the positive and the negative direction of the x axis respectively to obtained the images of the left and the right eyes. A mathematical model of shear transformation factor and stereo view depth is also discussed, therefore to control stereo effect quantitatively. The computational complexity is reduced in this algorithm to meet real time requirements, and the 3D effect can be adjusted to obtain good results. The algorithm is used to produce several 3D videos. The experimental results show that a satisfactory 3D effect can be got automatically and in real time.
An ultra low power transcutaneous impulse radio link for cochlea implants (2004)

The big potential of ultra wideband radio, in particular low power consumption, low power spectral density, high immunity against interference, affords many benefits, not only for consumer electronics, but also for medical devices. A cochlea implant is an electronic hearing apparatus, where a wireless link through human tissue is required. We propose a UWB link for a data rate of 1.2 Mbps and a propagation distance up to 500 mm. Transmitter, antennas and receivers are described and proposals for semiconductor integration are made.
Kinetics of composite particle formation during mechanical alloying. (Reannouncement with new availability information) (1993)

The kinetics of composite particle formation during attritor milling of insoluble binary elemental powders have been examined. The effects of processing conditions (i.e., mill power, temperature, and charge ratio) on these kinetics were studied. Particle size distributions and fractions of elemental and composite particles were determined as functions of milling time and processing conditions. This allowed the deduction of phenomenological rate constants describing the propensity for fracture and welding during processing. For the mill-operating conditions investigated, the number of particles in the mill generally decreased with milling time, indicating a greater tendency for particle welding than fracture. Moreover, a bimodal size distribution is often obtained as a result of preferential welding. Copper and chromium `alloy` primarily by encapsulation of Cr particles within Cu. This form of alloying also occurs in Cu-Nb alloys processed at low mill power and/or for short milling times. For other conditions, however, Cu-Nb alloys develop a lamellar morphology characteristic of mechanically alloyed two-phase ductile metals. Increasing mill power or charge (ball-to-powder weight) ratio (CR) increases the rate of composite particle formation.
Pose Estimation from Minimal Dual-Receiver Configurations (2013)

Using multiple receivers (microphones or antennas) in a rigid configuration, such as on a smartphone, it is possible to measure time difference of arrival to the receivers. This in turn can be used to determine the direction to the transmissions, if there are at least three receivers. When using two receivers it can be used to determine the angle to the transmissions relative to the line through the two receivers. In this paper we study three minimal problems for pose using such data: (i) determine position and orientation using five transmissions, (ii) determine position and orientation using four transmissions and known ’down ’ direction and (iii) determine position using three transmissions and known orientation. Numerically stable solvers are implemented. An experimental validation of the solvers are performed on simulated data. 1.
Optical Wireless Sensor Networks Based On Vlc With Plc-Ethernet Interface (2011)

We present a white LED-based optical wireless communication systems for indoor ubiquitous sensor networks. Each sensor node could access to the server through the PLC (Power Line Communication)-Ethernet interface. The proposed system offers a full-duplex wireless link by using different wavelengths to reduce the inter-symbol interference between uplink and downlink. Through the 1-to-n optical wireless sensor network and PLC modem, the mobile terminals send a temperature data to server. The data transmission speed and distance are 115.2kbps and about 60cm, respectively.
Epitope optimization of a DNA vaccine targeting SSX-2 leads to PD-1 upregulation on antigen-specific CD8 T cells and PD-L1 upregulation on tumor cells (2013)

Meeting abstracts Recent groups have shown that the immunological efficacy of vaccines could be increased by encoding targeted mutations that enhance the binding affinity between the encoded epitopes and the MHC-TCR complex. In this study, we sought to examine the anti-tumor efficacy of a DNA
Memory reconsolidation and its maintenance depend on L-voltage-dependent calcium channels and CaMKII functions regulating protein turnover in the hippocampus (2013)

Immediate postretrieval bilateral blockade of long-acting voltage-dependent calcium channels (L-VDCCs), but not of glutamatergic NMDA receptors, in the dorsal CA1 region of the hippocampus hinders retention of long-term spatial memory in the Morris water maze. Immediate postretrieval bilateral inhibition of calcium/calmodulin-dependent protein kinase (CaMK) II in dorsal CA1 does not affect retention of this task 24 h later but does hinder it 5 d later. These two distinct amnesic effects are abolished if protein degradation by proteasomes is inhibited concomitantly. These results indicate that spatial memory reconsolidation depends on the functionality of L-VDCC in dorsal CA1, that maintenance of subsequent reconsolidated memory trace depends on CaMKII, and these results also suggest that the role played by both L-VDCC and CaMKII is to promote the retrieval-dependent, synaptically localized enhancement of protein synthesis necessary to counteract a retrieval-dependent, synaptic-localized enhancement of protein degradation, which has been described as underlying the characteristic labilization of the memory trace triggered by retrieval. Thus, conceivably, L-VDCC and CaMKII would enhance activity-dependent localized protein renewal, which may account for the improvement of the long-term efficiency of the synapses responsible for the maintenance of reactivated long-term spatial memory.
Artificial intelligence applications for pre-implantation kidney biopsy pathology practice: a systematic review (2022)

All studies highlighted the importance of expert pathologist annotation to reliably train models and the need to acknowledge clinical nuances of the pre-implantation setting. Close cooperation between computer scientists and practicing as well as expert renal pathologists is needed, helping to refine the performance of AI-based models for routine pre-implantation kidney biopsy clinical practice.

Autonomous racing using learning Model Predictive Control (2017)

A novel learning Model Predictive Control technique is applied to the autonomous racing problem. The goal of the controller is to minimize the time to complete a lap. The proposed control strategy uses the data from previous laps to improve its performance while satisfying safety requirements. A system identification technique is proposed to estimate the vehicle dynamics. Simulation results with the high fidelity simulator software CarSim show the effectiveness of the proposed control scheme.
Protein kinase C activation disrupts epithelial apical junctions via ROCK-II dependent stimulation of actomyosin contractility (2009)

Our data suggest that stimulation of PKC disrupts epithelial apical junctions via ROCK-II dependent activation of NM II, which increases contractility of perijunctional actin filaments. This mechanism is likely to be important for cancer cell dissociation and tumor metastasis.

Rice Inositol Polyphosphate Kinase (OsIPK2) Directly Interacts with OsIAA11 to Regulate Lateral Root Formation (2017)

The plant hormone auxin controls many aspects of plant growth and development by promoting the degradation of Auxin/Indole-3-acetic acid (Aux/IAA) proteins. The domain II (DII) of Aux/IAA proteins is sufficient for eliciting the degradation by directly interacting with the auxin receptor F-box protein TIR1 to form a TIR1/AFBs-Aux/IAA complex in an auxin-dependent manner. However, the underlying mechanisms of fine-tuning Aux/IAA degradation by auxin stimuli remain to be elucidated. Here, we show that OsIPK2, a rice (Oryza sativa) inositol polyphosphate kinase, directly interacts with an Aux/IAA protein OsIAA11 to repress its degradation. In a rice protoplast transient expression system, the auxin-induced degradation of Myc-OsIAA11 fusion was delayed by co-expressed GFP-OsIPK2 proteins. Furthermore, expressing additional OsIPK2 or its N-terminal amino acid sequence enhanced the accumulation of OsIAA11 proteins in transgenic plants, which in turn caused defects in lateral root formation and auxin response. Taken together, we identify a novel co-factor of Aux/IAA in auxin signaling and demonstrate its role in regulating lateral root development.
Superconcentrators of Density 25.3 (2014)

An $N$-superconcentrator is a directed, acyclic graph with $N$ input nodes and $N$ output nodes such that every subset of the inputs and every subset of the outputs of same cardinality can be connected by node-disjoint paths. It is known that linear-size and bounded-degree superconcentrators exist. We prove the existence of such superconcentrators with asymptotic density $25.3$ (where the density is the number of edges divided by $N$). The previously best known densities were $28$ \cite{Scho2006} and $27.4136$ \cite{YuanK12}.
Three optical cycle mid-IR Kerr-lens mode-locked polycrystalline Cr^2+:ZnS laser (2015)

We report Kerr-lens mode-locked polycrystalline Cr(2+):ZnS lasers at 2.4 μm central wavelength optimized for short pulse duration. By control of the second- and third-order dispersion within 500 nm bandwidth we obtained pulses of three optical cycles (<29 fs) at 100 MHz repetition rate with 0.44 W average power. The emission spectrum is 240 nm broad at -3 dB level and spans 950 nm at -30 dB level. Transform-limited 38 fs pulses were obtained at 300 MHz repetition rate with 700 mW average power. To the best of our knowledge these are the shortest reported to-date pulses from Cr(2+):ZnS and Cr(2+):ZnSe lasers.
Analysis of Flavonoids and Hydroxycinnamic Acid Derivatives in Rapeseeds (Brassica napus L. var. napus) by HPLC-PDA–ESI(−)-MSn/HRMS (2014)

A comprehensive description of flavonoids and hydroxycinnamic acid derivatives in Brassica napus L. var. napus seeds is important to improve rapeseed quality. HPLC-PDA-ESI(-)-MS(n)/HRMS has been broadly applied to study phenolic compounds in plants. In the present study, crude phenolic compounds extracted from rapeseed were subjected to column chromatography, alkaline hydrolysis, and HPLC-PDA-ESI(-)-MS(n)/HRMS analysis. A total of 91 flavonoids and hydroxycinnamic acid derivatives were detected, including 39 kaempferol derivatives, 11 isorhamnetin derivatives, 5 quercetin derivatives, 6 flavanols and their oligomers, and 30 hydroxycinnamic acid derivatives. A total of 78 of these compounds were tentatively identified; of these, 55 were reported for the first time in B. napus L. var. napus and 24 were detected for the first time in the genus Brassica. This research enriches our knowledge of the phenolic composition of rapeseed and provides a reliable guide for the selection of rapeseed with valuable breeding potential.
Collapse of the advanta V12 large diameter covered stent following implantation for aortic coarctation (2013)

We report a case of collapse of the Advanta V12 Large Diameter (LD) covered stent following previous successful implantation for native aortic coarctation. This unreported complication was successfully managed with subsequent stent redilation and implantation of two covered Cheatham-Platinum stents within the collapsed Advanta V12 stent. This case highlights the importance of correct stent apposition to the aortic wall and also raises some concerns regarding the radial strength of the Advanta V12 stent.
New Generation of Liposomes Called Archaeosomes Based on Natural or Synthetic Archaeal Lipids as Innovative Formulations for Drug Delivery (2009)

Archaeosomes made from natural archaeal membrane lipids and/or synthetic lipid analogues have been extensively studied for potential applications in drug and vaccine delivery over the past decade only. Archaeal-type lipids consist of archaeol (diether) and/or caldarchaeol (tetraether) core structures wherein regularly branched and usually fully saturated phytanyl chains (20-40 carbons in lengths), are attached via ether bonds to the sn-2,3 carbons of the glycerol backbone. Archaeosomes constitute a novel generation of liposomes that exhibit high stabilities to low or high temperatures, acidic or alkaline pH, oxidative conditions, high pressure, action of phospholipases, bile salts and serum proteins. These properties associated with a good safety profile are beneficial for nanotechnological applications in drug and gene delivery. Additionally, archaeosome formulations could be used as efficient carriers of antigens and/or adjuvants promoting antigen-specific, humoral and cell-mediated immune responses, in addition to antigen-specific mucosal immune responses in the vaccinated hosts. The immune responses are well sustained over time, and are subject to strong memory responses. Nanodelivery-based vaccinations using archaeosomes could then represent a promising approach for treating and preventing infections, allergies, and neoplastic or cancer diseases. In this review, the few recent US, World and European patents developing archaeosomes for these biotechnological applications in Health are discussed.
Atrans-AB-Bacteriochlorin Building Block (2011)

Synthetic bacteriochlorins are of interest for fundamental studies in photochemistry because of their strong absorption in the near-infrared spectral region and close similarity with natural bacteriochlorophylls. A de novo route to 5-methoxybacteriochlorins entails self-condensation of a dihydrodipyrrin-acetal, which in turn is prepared from a 2-(2-nitroethyl)pyrrole species and an α,β-unsaturated ketone-acetal (e.g., 1,1-dimethoxy-4-methylpent-3-en-2-one). Here, four new results are reported concerning the synthesis of substituted bacteriochlorins. First, a new, scalable route to 1,1-dimethoxy-4-methylpent-3-en-2-one removes a significant previous impediment to the overall route. Second, the new route was employed to gain access to new α,β-unsaturated ketones and corresponding dihydrodipyrrins bearing alternative substituents in place of the dimethoxy unit. Third, a dihydrodipyrrin bearing a 1,3-dioxolan-2-yl moiety afforded the bacteriochlorin (30% yield) containing a 2-hydroxyethoxy substituent at the 5-position. Fourth, subsequent bromination proceeded regioselectively at the 15-position to give a trans-(5,15)-AB-bacteriochlorin building block. The linear 5,15-substitution pattern is attractive for a number of molecular designs. The results taken together afford deeper understanding of the scope and limitations of the de novo route and also advance the capabilities for tailoring synthetic bacteriochlorins.
Storage and Feeding of Particulate Solids (1995)

Many forms of problems arise in the operation of bulk solids storage and feeding systems. Almost invariably these arise due to the nature of the bulk material, rather than from mechanical consideration. The first step of design is to register the relevant properties of the particular solid, in all the forms it has to be handled. An understanding of the bulk stress systems, balanced with modern technology and equipment practice, then enables reliable plant to be constructed. Storage and feeding installations must however be considered as an integrated system, as variations in the condition of the product through the history of the total flow route may well influence performance. Many forms of hopper and feeder problems are described, including interfacing and discharging characteristics. The advantages and limitations of screw feeders are discussed, including their construction and performance features.
Learning hysteroscopy sterilization and the Ovabloc System with Hyskon. (1987)

A review of the first 100 and the last 100 patients in a series of 268 patients sterilized by hysteroscopic injection of liquid silicone into the fallopian was made to evaluate the success rate as it relates to experience with the procedure. The two groups were similar in composition. While the percentage of patients sterilized increased only from 91% in the first 100 patients to 94% in the last 100 patients the numbers that were sterilized at the time of the first procedure increased by 9%. The two major reasons for repeated procedures were tip separation and tubal spasm. The former may become less of a problem with new manufacturing changes. Tubal spasm was reduced as a problem by controlling the temperature of Hyskon but it remains a difficult problem in a smaller number of patients even in the last group. Other causes for repeated procedures were primarily related to operator inexperience and investigational problems. They appear not to be a significant problem for physicians who will learn this procedure in future. This procedure is well received by patients. Hysteroscopists will find it a valuable outpatient female sterilization technique.
Characterization of degraded hydrogels based on poly(vinyl alcohol) grafted with poly(lactide‐co‐glycolide) (2010)

Abstract Poly(vinyl alcohol) (PVA) grafted with poly(lactide‐ co ‐glycolide) and cross‐linked as a material of increased hydrophobicity relative to PVA was produced. The properties were examined with respect to the mass loss, water uptake, hydrophilicity, and mechanical characteristics upon hydrolytical degradation. The hydrogels investigated display water uptake increasing with degradation time because of increasing hydrophilicity. The mass loss amounts up to 15% after eight weeks of degradation. The mechanical properties of the hydrogels are within the range of those of natural tissue, the E modulus is 18 MPa, or even 100–200 MPa, depending on the structure of material. The mechanical characteristic and their dependence degradation show the most recognizable correlation with the chemical structure. Studies of the topography of degraded samples (scanning electron microscopy) and IR measurements demonstrate the degradation to occur at slow rate due to the high degree of grafting. The mass loss is rather low and a bulk degradation mechanism takes place. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Morphological and Dimensional Control via Hierarchical Assembly of Doped Oligoaniline Single Crystals (2012)

Single crystals of doped aniline oligomers are produced via a simple solution-based self-assembly method. Detailed mechanistic studies reveal that crystals of different morphologies and dimensions can be produced by a “bottom-up” hierarchical assembly where structures such as one-dimensional (1-D) nanofibers can be aggregated into higher order architectures. A large variety of crystalline nanostructures including 1-D nanofibers and nanowires, 2-D nanoribbons and nanosheets, 3-D nanoplates, stacked sheets, nanoflowers, porous networks, hollow spheres, and twisted coils can be obtained by controlling the nucleation of the crystals and the non-covalent interactions between the doped oligomers. These nanoscale crystals exhibit enhanced conductivity compared to their bulk counterparts as well as interesting structure–property relationships such as shape-dependent crystallinity. Furthermore, the morphology and dimension of these structures can be largely rationalized and predicted by monitoring molecule–solvent interactions via absorption studies. Using doped tetraaniline as a model system, the results and strategies presented here provide insight into the general scheme of shape and size control for organic materials.
Mammalian actin-related protein 2/3 complex localizes to regions of lamellipodial protrusion and is composed of evolutionarily conserved proteins (1997)

Human neutrophils contain a complex of proteins similar to the actin-related protein 2/3 (Arp2/3) complex of Acanthamoeba. We have obtained peptide sequence information for each member of the putative seven-protein complex previously described for Acanthamoeba and human platelets. From the peptide sequences we have identified cDNA species encoding three novel proteins in this complex. We find that in addition to Arp2 and Arp3, this complex contains a relative of the human (Suppressor of Profilin) SOP2Hs protein and four previously unknown proteins. These proteins localize in the cytoplasm of fibroblasts that lack lamellipodia, but are enriched in lamellipodia on stimulation with serum or platelet-derived growth factor. We propose a conserved and dynamic role for this complex in the organization of the actin cytoskeleton.
