Passivation and Activation of Iron in the Presence of Molybdate Ions (1968)

In extension of previous studies of the mechanism of the action of XO4n− inhibitors of corrosion, the behavior of MoO42− ions has been investigated. This inhibitor was found to exert a noncathodic action in facilitating anodic passivation, but the phenomena are more complex than those exhibited by CrO42−, TCO4−, and MnO4−. The transition between active and passive potentials comprises several well-defined stages which were identified in potentiostatic measurements. The character of surface films was studied as a function of potential, both by analytical procedures and by electron microscopy and diffraction. The existence of mixed complex species containing Fe(II), Fe(III), and Mo(VI) in solution was established spectro-photometrically and solids having such compositions were synthesized. A super passive state was found to be produced at noble potentials when ferrous ions were present in sufficient concentration, and the dependence of all transition potentials upon pH was established. An interpretation of the processes occurring in the different regions of potential is presented, and deductions from the super passive behavior are extended to a generalized theory of the passive state.
Instance-Level Heterogeneous Domain Adaptation for Limited-Labeled Sketch-to-Photo Retrieval (2020)

Although sketch-to-photo retrieval has a wide range of applications, it is costly to obtain paired and rich-labeled ground truth. Differently, photo retrieval data is easier to acquire. Therefore, previous works pre-train their models on rich-labeled photo retrieval data (i.e., source domain) and then fine-tune them on the limited-labeled sketch-to-photo retrieval data (i.e., target domain). However, without co-training source and target data, source domain knowledge might be forgotten during the fine-tuning process, while simply co-training them may cause negative transfer due to domain gaps. Moreover, identity label spaces of source data and target data are generally disjoint and therefore conventional category-level Domain Adaptation (DA) is not directly applicable. To address these issues, we propose an Instance-level Heterogeneous Domain Adaptation (IHDA) framework. We apply the fine-tuning strategy for identity label learning, aiming to transfer the instance-level knowledge in an inductive transfer manner. Meanwhile, labeled attributes from the source data are selected to form a shared label space for source and target domains. Guided by shared attributes, DA is utilized to bridge cross-dataset domain gaps and heterogeneous domain gaps, which transfers instance-level knowledge in a transductive transfer manner. Experiments show that our method has set a new state of the art on three sketch-to-photo image retrieval benchmarks without extra annotations, which opens the door to train more effective models on limited-labeled heterogeneous image retrieval tasks.
(Co)polymers of L‐lactide, 1. Synthesis, thermal properties and hydrolytic degradation (1994)

Abstract Copolymers of L ‐lactide with D ‐lactide According to IUPAC the name dilactide is preferred to lactide. , glycolide IUPAC name: diglycolide. , ε‐caprolactone and trimethylene carbonate, and networks with spiro‐bis‐dimethylene‐carbonate (2,4,7,9‐tetraoxaspiro[5.5]undecane‐3,8‐dione) were prepared in bulk at standardized polymerization conditions. The properties of the nascent copolymers were evaluated with respect to the nature of the comonomer. Copolymerization with comonomers entailing low glass transition temperature simultaneously reduces the crystallinity. 300 MHz 1 H nuclear magnetic resonance is shown to be a useful technique for the determination of the average monomer sequence lengths in ε‐caprolactone and trimethylene carbonate copolymers. The presence of crystallizable L ‐lactide sequences, due to differences in monomer reactivity, has a large effect on the thermal properties of the copolymer as well as on the long‐term degradation characteristics.

Influence of Al2O3 content on hydraulic reactivity of granulated blast-furnace slag, and the interaction between Al2O3 and CaO (2004)

This paper presents results of investigations on the influence of the Al 2 O 3 content of granulated blast-furnace slag (GBFS) on its hydraulic reactivity. Al 2 O 3 content up to 15% has a positive effect on the reactivity of GBFS. Due to the interaction between the Al 2 O 3 and CaO contents the effectiveness of the Al 2 O 3 depends also on the CaO content, which is clearly more significant in lime-rich slags than in slags that are poor in lime. For the optimisation of the quality of GBFS it is recommended to maintain Al 2 O 3 over 10·5% and CaO over 40%. It was found by 27 Al NMR investigation that aluminium in GBFS is mainly tetrahedrally coordinated. However with rising Al 2 O 3 so-called ‘tricluster’ is formed in the slag glasses. This leads to a reactivity reduction.
Enhanced proteotoxic stress: one of the contributors for hyperthermic potentiation of the proteasome inhibitor bortezomib using magnetic nanoparticles (2014)

The induction of hyperthermia using nanoparticles, known as magnetic fluid hyperthermia (MFH) in combination with anti-cancer drugs is an attractive method because of the potential for enhanced anti-cancer effects. Recent studies have shown that cells treated with MFH are more sensitive to the proteasome inhibitor bortezomib (BZ) than cells treated by hot water hyperthermia (HWH) under the same temperature conditions. We hypothesized that enhanced proteotoxic stress, caused by a combination of microtubule damage and an increase in the amount of aggregated proteins, may be partially responsible for this observation. To test this hypothesis MCF-7 cells were exposed to hyperthermic treatment (MFH or HWH) at 43 °C or 45 °C for 30 minutes. Then, aggresome formation and microtubule disruption studies at 30 minutes or 2.5 hours of recovery time were performed to evaluate the progressive effects induced by the two treatments. Cell viability at short and long times was evaluated. Aggresome formation and microtubule disruption results suggested that one of the mechanisms by which MFH enhances BZ cytotoxicity is the formation and subsequent accumulation of aggregated proteins in the cytosol due to the interruption of their transport to the perinuclear area through microtubules. Our data show evidence that MFH induces a more toxic and unmitigated proteotoxic stress than HWH under similar temperature conditions.
Markov Decision Process Model for Path Selection Algorithm on Multi-Business System with Services Composition (2010)

Services composition can reorganize a variety of heterogeneous network services to form new businesses on the multi-service streaming media system, which can speed up the development and deployment of new services. In this paper, a three layer model is used to describe the service composition in a streaming media system. In order to improve the real-time request response performance, path selection is divided into two steps, the initial paths planning and dynamic path selection. The dynamic path selection behavior is described by using Markov decision processes model. When QoS is guarded, the policy iteration algorithm is adopted to improve the system of the total receipts and to reduce the refuse rate. The simulation results show that the proposed method of service composition improves the performance of the streaming media system.
Magnetocaloric Effect and Magnetic Properties of High Pressure Synthesized RhFe Compound (2012)

The studies of X-ray diffraction, magnetization, magnetocaloric effect, and 57Fe Mössbauer spectra have been performed in a bulk sample of RhFe compound synthesized under high pressure. It have been found that RhFe has fcc-type of crystal structure at room temperature and, shows the first order magnetic transition from the antiferromagnetic-like to ferromagnetic state close to 338 K at 5T magnetic field. This type of behavior has been verified by differential scanning calorimetry, magnetization and Mössbauer techniques. The irreversible transition from antiferromagnetic to stable ferromagnetic state has been observed after heating of sample up to 573K.
Automated design of CRISPR prime editors for thousands of human pathogenic variants (2020)

Abstract Prime editors (PEs) are CRISPR-based genome engineering tools that can introduce precise base-pair edits at specific locations in the genome. These programmable gene editors have been predicted to repair 89% of known human pathogenic variants in the ClinVar database, although these PE constructs do not presently exist. Towards this end, we developed an automated pipeline to correct (therapeutic editing) or introduce (disease modeling) human pathogenic variants that optimizes the design of several RNA constructs required for prime editing and avoids predicted off-targets in the human genome. However, using optimal PE design criteria, we find that only a small fraction of these pathogenic variants can be targeted. Through the use of alternative Cas9 enzymes and extended templates, we increase the number of targetable pathogenic variants to &gt;50,000 variants and make these pre-designed PE constructs accessible through a web-based portal ( http://primeedit.nygenome.org ). Given the tremendous potential for therapeutic gene editing, we also assessed the possibility of developing universal PE constructs. By examining the overlap of different PE components with common human genetic variants in dbSNP, we find that common variants affect only a small minority of designed PEs.
Determining the gelation temperature of β-lactoglobulin using in situ microscopic imaging (2013)

Evolution of microstructure during heat-induced gelation of β-lactoglobulin (β-LG) was investigated in situ using confocal laser scanning microscopy at various gel-preparation conditions: pH=2, 5, and 7; protein content=5, 10, and 15%; and salt (NaCl) content=0, 0.1, and 0.3 M. The number and area of evolving β-LG clusters were observed as a function of time and temperature and the data were fitted to a log-normal model and sigmoid model, respectively. The gelation temperature (Tgel) of the β-LG system was determined from both the number (Tgel/N) and total area (Tgel/A) of β-LG clusters versus temperature data. The range of Tgel/N and Tgel/A values for all the cases was 68 to 87°C. The effect of pH was the most dominant on Tgel/N and Tgel/A, whereas the effects of β-LG and salt contents were also statistically significant. Therefore, the combined effect of protein concentration, pH, and salt content is critical to determine the overall gel microstructure and Tgel. The Tgel/N and Tgel/A generally agreed well with Tgel determined by dynamic rheometry (Tgel/R). The correlations between Tgel/N and Tgel/A versus Tgel/R were 0.85 and 0.72, respectively. In addition, Tgel/N and Tgel/A values compared well with Tgel/R values reported in the literature. Based on these results, Tgel/N determined via in situ microscopy appears to be a fairly good representative of the traditionally measured gelation temperature, Tgel/R.
Macrolide Resistance and Detection in <i>Mycoplasma pneumoniae </i>at Kansai Medical University Hirakata Hospital (2011)

Mycoplasma pneumoniae causes bronchitis and pneumonia predominantly in subjects 5 to 20 years old. M. pneumoniae is detected by measuring specific antibodies and/or isolating the microorganism, but the frequency of false-positive/negative results, and the culture time required until isolation pose problems. We detected M. pneumoniae using real-time PCR with clinical specimens. We also determined the drug sensitivity of isolated M. pneumoniae and searched for the gene mutation responsible for macrolide resistance. In 275 cases of suspected M. pneumoniae infection, positive cases in real-time PCR numbered 40 (14.5%). Of these, 16 showed positive culture (5.8%). Of these 16, A2063G point mutation that causes macrolide resistance was found in 12. Drug sensitivity testing showed resistance to clarithromycin (MIC> or =64 microg/ml) in 11 and susceptibility in 4 (MIC 0.0039 microg/ml). The clarithromycin resistance ratio was 75%. Growth was insufficient for testing in 1 case. M. pneumoniae was susceptible to minocycline and all quinolone drugs. M. pneumoniae detection using real-time PCR proved much more sensitive than conventional culture. Macrolide resistance results correlated well with genomic mutation. Our study's macrolide resistance ratio was high at 75% possibly due to a restricted subject population that had been administered macrolide drugs elsewhere but with an unsatisfactory outcome. The increasing number of reports on macrolide resistance requires that we monitor drug resistance trends, particularly among macrolide derivatives.
The biophysical basis of receptor tyrosine kinase ligand functional selectivity: Trk-B case study (2020)

Tropomyosin receptor kinase B (Trk-B) belongs to the second largest family of membrane receptors, Receptor Tyrosine Kinases (RTKs). Trk-B is known to interact with three different neurotrophins: Brain-Derived Neurotrophic Factor (BDNF), Neurotrophin-4 (NT-4), and Neurotrophin-3 (NT-3). All three neurotrophins are involved in survival and proliferation of neuronal cells, but each induces distinct signaling through Trk-B. We hypothesize that the different biological effects correlate with differences in the interactions between the Trk-B receptors, when bound to different ligands, in the plasma membrane. To test this hypothesis, we use quantitative FRET to characterize Trk-B dimerization in response to NT-3 and NT-4 in live cells, and compare it to the previously published data for Trk-B in the absence and presence of BDNF. Our study reveals that the distinct Trk-B signaling outcomes are underpinned by both different configurations and different stabilities of the three ligand-bound Trk-B dimers in the plasma membrane.
Research of bird's-eye panoramic view for vehicle parking (2011)

This paper proposed a method to integrate multiple images from a video captured by the camera sticked on the back of a vehicle. The integration can be performed in real time. The image integration consists of two steps: Perspective transform and stitching. First, do camera calibration to get the intrinsic parameters and extrinsic parameters with camera calibration and get the birds-eye view of each image. Then detect the line of each image using Hough Transform. After gained the line histogram, gets the rotation angle between two images using minimum cross-correlation of line histogram. Use minimum cross-correlation of binary images to get the transform pixel in horizontal direction and vertical direction. Do spatial transform for one image to gain the images' coordinate in the same coordinate system. Add two images with different weight to get stitching image.
Local and Global Information in Obstacle Detection on Railway Tracks (2023)

Reliable obstacle detection on railways could help prevent collisions that result in injuries and potentially damage or derail the train. Unfortunately, generic object detectors do not have enough classes to account for all possible scenarios, and datasets featuring objects on railways are challenging to obtain. We propose utilizing a shallow network to learn railway segmentation from normal railway images. The limited receptive field of the network prevents overconfident predictions and allows the network to focus on the locally very distinct and repetitive patterns of the railway environment. Additionally, we explore the controlled inclusion of global information by learning to hallucinate obstacle-free images. We evaluate our method on a custom dataset featuring railway images with artificially augmented obstacles. Our proposed method outperforms other learning-based baseline methods.
Image-Guided Radiation Therapy: Current and Future Directions (2006)

Since its discovery, ionizing radiation has been a cornerstone of cancer treatment. In step with technological advances, radiation therapy has strived to increase its therapeutic ratio. With the advent of 3D and cross-sectional imaging, and the ability to modulate the radiation beam, the current age of radiation oncology was initiated, promising better tumor control rates with fewer side effects. However, these ever more precise and conformal treatments have also revealed the importance of accounting for organ and tumor motion. Efforts to understand and compensate for the uncertainties caused by movement are required to ensure accurate conformal radiation therapy. This review will explore the current and future directions of image-guided radiation therapy, whose goal is to increase the accuracy of radiotherapy.

Diffuse lamellar keratitis in the femtosecond-assisted LASIK flap tunnel (2014)

Here we report a case of a 29-year-old myopic female who underwent femtosecond laser-assisted in situ keratomileusis (LASIK) and, on the first postoperative day slit-lamp examination revealed a dense, white, granular reaction with the presence of some blood droplets (stage I diffuse lamellar keratitis [DLK]) in her left eye, specifically localized into the femtosecond LASIK flap tunnel (not extended to the flap interface). The patient received intensive treatment with topical corticosteroids and 5 days later the granular reaction had completely resolved. A new site of DLK, ie, the flap tunnel, in femtosecond-assisted LASIK is presented. DLK into the flap tunnel could be managed with corticosteroids if detected early, without affecting the flap interface.

A New Type of Motor: Pneumatic Step Motor (2007)

This paper presents a new type of pneumatic motor, a pneumatic step motor (PneuStep). Directional rotary motion of discrete displacement is achieved by sequentially pressurizing the three ports of the motor. Pulsed pressure waves are generated by a remote pneumatic distributor. The motor assembly includes a motor, gearhead, and incremental position encoder in a compact, central bore construction. A special electronic driver is used to control the new motor with electric stepper indexers and standard motion control cards. The motor accepts open-loop step operation as well as closed-loop control with position feedback from the enclosed sensor. A special control feature is implemented to adapt classic control algorithms to the new motor, and is experimentally validated. The speed performance of the motor degrades with the length of the pneumatic hoses between the distributor and motor. Experimental results are presented to reveal this behavior and set the expectation level. Nevertheless, the stepper achieves easily controllable precise motion unlike other pneumatic motors. The motor was designed to be compatible with magnetic resonance medical imaging equipment, for actuating an image-guided intervention robot, for medical applications. For this reason, the motors were entirely made of nonmagnetic and dielectric materials such as plastics, ceramics, and rubbers. Encoding was performed with fiber optics, so that the motors are electricity free, exclusively using pressure and light. PneuStep is readily applicable to other pneumatic or hydraulic precision-motion applications.
Structural basis of ligand selectivity by a bacterial adhesin lectin involved in multi- species biofilm formation (2020)

Abstract Carbohydrate recognition by lectins governs critical host-microbe interactions. MpPA14 lectin is a domain of a 1.5-MDa adhesin responsible for a symbiotic bacterium-diatom interaction in Antarctica. Here we show Mp PA14 binds various monosaccharides, with L-fucose and N-acetyl glucosamine being the strongest ligands (K d ~ 150 μM). High-resolution structures of Mp PA14 with 15 different sugars bound elucidated the molecular basis for the lectin’s apparent binding promiscuity but underlying selectivity. Mp PA14 mediates strong Ca 2+ -dependent interactions with the 3, 4 diols of L-fucopyranose and glucopyranoses, and binds other sugars via their specific minor isomers. Thus, Mp PA14 only binds polysaccharides like branched glucans and fucoidans with these free end-groups. Consistent with our findings, adhesion of Mp PA14 to diatom cells was selectively blocked by L-fucose, but not by N-acetyl galactosamine. With Mp PA14 lectin homologs present in adhesins of several pathogens, our work gives insight into an anti-adhesion strategy to block infection via ligand-based antagonists.
Model of Electron Cloud Build up with Secondary Ion-Electron Emission as a Source of Delayed Electrons (2006)

Beam particle leaking to the gap and anomaly high reflectivity of low energy electrons in collision with pipe wall was proposed as explanation of anomalously long electron cloud survival after the gap between bunches. Another possibility of secondary electron generation with a long delay time after bunch passing is the secondary ion-electron emission. The model of electron cloud build up with secondary ion-electron emission as the source of delayed electrons is presented and discussed. This model can be used for the explanation of bunched beam instability in Los Alamos PSR with electron survival after the gap, for the prediction of e-cloud generation in SNS, and can be important for the pressure rise in warm and cold sections of RHIC. A fast desorbtion by ion of physically adsorbed molecules can explain the "first pulse instability" observed in LA PSR.

Plasma and magnetohydrodynamic problems in vacuum consumable arc remelting (1982)

The results of this study confirm the presence of lubricin in the human intervertebral disc and demonstrate a unique distribution compared with that in the goat. The presence of lubricin in asymptomatic discs provides a foundation for future research regarding the role of lubricin in pathological disc conditions.
Activities of amoxicillin and clavulanic acid combinations against urinary tract infections (1982)

Urinary tract infection caused by beta-lactamase-producing bacteria were treated with 500 mg of amoxicillin three times daily plus either 250 or 125 mg of clavulanic acid three times daily. The overall cure rate was 63.6%, 77.7% with the high dose of clavulanic acid and 53.8% with the low dose. Gastrointestinal intolerance was common in the high-dose clavulanic acid regimen.
