Highly Efficient LaCoO 3 Nanofibers Catalysts for Photocatalytic Degradation of Rhodamine B (2010)

Perovskite‐type oxide LaCoO 3 nanofibers have been fabricated by electrospinning and subsequent calcination technology. Scanning electron microscopy, transmission electron microscopy, and X‐ray diffraction were used to characterize the morphology and structure. Rhodamine B (RhB) was used to evaluate the ultraviolet photocatalytic activity of the as‐prepared nanofibers. The effect of calcination temperature and pH of the reaction solution on the decolorization of RhB were investigated. Results showed that the samples calcined at 600°C exhibited the best photocatalytic activity at pH 4. Additionally, the recycling experiments confirmed the attractive stability of the catalysts.
Plasmonics without negative dielectrics (2016)

Some of the plasmonic phenomena can be imitated by exploiting the structural dispersion of parallel-plate waveguides filled with positive dielectrics. This synthetic platform, as a test bed for exploring plasmonic features, is more suitable for longer-wavelength regimes and may exhibit lower loss, since positive dielectric materials are utilized.
Sliding mode attitude control of a small satellite for ground tracking maneuvers (2000)

This paper deals with spacecraft attitude control using sliding mode techniques. Two distinctions of the proposed method from most reported methods are: 1) the measure of attitude error used is intrinsically defined, Euclidean-geometric, and intuitive; and 2) a novel, dynamically nonlinear sliding function is used that results in a simple control law. As an example we consider the ground station tracking of UASat.

Perception of Plane Orientation From Self-Generated and Passively Observed Optic Flow (2007)

We investigate the perception of 3D plane orientation---focusing on the perception of tilt---from optic flow generated by the observer&amp;apos;s movement around a simulated stationary object, and compare the performance to that of an immobile observer receiving a replay of the same optic flow. We find that perception of plane orientation is more precise in the active than in the immobile case. In particular, in the case of the immobile observer the presence of shear in optic flow drastically diminishes the precision of tilt perception, whereas in the active observer this decrease in performance is greatly reduced. Furthermore, perceived slant is better correlated with simulated slant in the active observer. We conclude with a discussion of possible systematic biases in tilt perception from optic flow, as well as of various theoretical explanations for our results.

B. F. Hoskins, F. D. Whillans, D. H. Dale and D. C. Hodgkin, J. Chem. Soc. D, 1969, 69 DOI: 10.1039/C29690000069
Protection from Pseudorabies Virus Challenge in Mice by a Combination of Purified gII, gIII and gVI Antigens. (1992)

The antigens gII, gIII and gVI were purified from the lysates of the pseudorabies virus (PRV) -infected HmLu-1 cells using Sepharose 4 B coupled with MAbs against these antigens. Mice immunized with either gII, gIII, gVI antigen or a mixture of them were challenged intraperitoneally with 8.5 x 10(3) plaque forming units of PRV. All the mice immunized with 1.5 and 4.5 micrograms of the mixture and 4.5 micrograms of the gIII antigen survived. The sera of mice immunized with the mixture had virus neutralizing activity which was independent of complement, hemagglutination inhibition activity, and recognized major (93 kilodaltons) and minor (129, 74, 68 and 50 kilodaltons) PRV proteins under reducing conditions in western blotting. The serological activity levels in the lower survival group were not different from those in the complete survival. These results indicate that the mixture of each glycoprotein is more effective for eliciting of protective immunities in mice and that serological activity do not always correlate with protection.
An Allylic Rearrangement Arising from Reaction of Fluoride Ion and A 3-Chloro, 4,5-Unsaturated Uronate Derivative (1985)

Abstract Reaction of methyl [benzyl 2-[(benzyloxycarbonyl)-amino]-3-chloro-2,3,4-trideoxy-β-L-threo-hex-4-enopyrano-sid]uronate,3,4-trideoxy-β-L-threo-hex-4-enopyranosidjuronate (7) with silver fluoride gave the 5-fluoro, 3,4-unsaturated uronate derivative 8, which, on treatment with methanolic ammonia, afforded the corresponding 5-meth-oxy, uronamide 9. The structures of 8 and 9 were confirmed by spectral data and by x-ray crystallographic analysis of 8. 1H NMR spectroscopy parameters for 9 and its diastercomen 11 have been used to probe the conformational preferences in solution.
Multiscale Frequent Co-movement Pattern Mining (2020)

Thanks to recent prevalence of location tracking technologies, collecting massive spatiotemporal datasets containing moving object trajectories has become possible, providing an exceptional opportunity to derive interesting insights about the behavior of moving objects such as people, animals, and vehicles. In particular, mining patterns from "co-movements" of objects (such as movements by players of a sports team, joints of the human body while walking, and vehicles in a transportation network) can lead to the discovery of interesting patterns (e.g., offense tactics of a sports team, gait signature of a person, and driving behaviors causing heavy traffic). Various trajectory mining and frequent pattern mining techniques have been proposed to discover patterns in trajectory datasets and more generally, event sequences. However, existing approaches are inapplicable for co-movement pattern mining from multi-trajectory datasets. In this paper, we propose a novel and efficient framework for co-movement pattern mining. We also extend this framework for efficient mining of such patterns at multiple spatial scales. The performance of the proposed solutions is evaluated by conducting extensive experiments using two real datasets, a soccer game dataset and a human gait dataset. Our experimental results show that our proposed algorithms are promising.
Terahertz CARS microscopy (2019)

Biomacromolecules are believed to exhibit rich vibrational spectra in the terahertz region. Yet, vibrationally-resolved high-resolution imaging in this spectral region is extremely challenging. Here, we develop a terahertz coherent anti-Stokes Raman scattering (THz-CARS) microscope, showing chemically-selective imaging of biological tissues using low-frequency collective modes of biomacromolecules, and filling the existing energy scale gap for vibrational imaging in the THz region (&lt;300cm-1).

A Comparison of Computer Codes for the Propagation of Sonic Booms Through Realistic Atmospheres Utilizing Actual Acoustic Signatures (1996)

A numerical exercise to compare computer codes for the propagation of sonic booms through the atmosphere is reported. For the initial portion of the comparison, artificial, yet realistic, waveforms were numerically propagated through identical atmospheres. In addition to this comparison, one of these codes has been used to make preliminary predictions of the boom generated from a recent SR-71 flight. For the initial comparison, ground waveforms are calculated using four different codes or algorithms: (1) weak shock theory, an analytical prediction, (2) SHOCKN, a mixed time and frequency domain code developed at the University of Mississippi, (3) ZEPHYRUS, another mixed time and frequency code developed at the University of Texas, and (4) THOR, a pure time domain code recently developed at the University of Texas. The codes are described and their differences noted.
Novel β-Secretase Cleavage of β-Amyloid Precursor Protein in the Endoplasmic Reticulum/Intermediate Compartment of NT2N Cells (1997)

Previous studies have demonstrated that NT2N neurons derived from a human embryonal carcinoma cell line (NT2) constitutively process the endogenous wild-type beta-amyloid precursor protein (APP) to amyloid beta peptide in an intracellular compartment. These studies indicate that other proteolytic fragments generated by intracellular processing must also be present in these cells. Here we show that the NH2-terminal fragment of APP generated by beta-secretase cleavage (APPbeta) is indeed produced from the endogenous full length APP (APPFL). Pulse-chase studies demonstrated a precursor-product relationship between APPFL and APPbeta as well as intracellular and secreted APPbeta fragments. In addition, trypsin digestion of intact NT2N cells at 4 degrees C did not abolish APPbeta recovered from the cell lysates. Furthermore, the production of intracellular APPbeta from wild-type APP appears to be a unique characteristic of postmitotic neurons, since intracellular APPbeta was not detected in several non-neuronal cell lines. Significantly, production of APPbeta occurred even when APP was retained in the ER/ intermediate compartment by inhibition with brefeldin A, incubation at 15 degrees C, or by expression of exogenous APP bearing the dilysine ER retrieval motif.
Adenovirus Mediated Gelsolin Gene Therapy for Orthotopic Human Bladder Cancer in Nude Mice (2002)

Ad-GSN provides a significant tumor suppressive effect on human bladder cancer cells in this orthotopic nude mouse model. Adenovirus mediated over expression of gelsolin may be useful therapy for human bladder cancer.
Commentary on myocardial stunning and its clinical relevance (1996)

Left ventricular dysfunction is in most cases the consequence of myocardial ischaemia. It may occur transiently after a short episode of ischaemia and is usually reversible. It may persist over hours or even days in patients after an episode of ischaemia followed by reperfusion, leading to the so-called condition of stunning (1).
Recombination‐Based Assay (RBA) for Screening Bacteriophage Lambda Libraries (1994)

The recombination-based assay represents a convenient way to screen a complex library constructed in bacteriophage lambda for homology to a given sequence cloned into a specially designed plasmid. The technique serves to screen a bacteriophage library rapidly and efficiently with a sequence cloned into a plasmid; counterselection then yields the gene product of interest with its plasmid carrier deleted. Because 10(6) to 10(7) plaque-forming units (pfu) may be screened using several petri dishes, and the homology for crossing-over need only be greater than 25 bp, the RBA represents an efficient way to screen complex lambda libraries rapidly for homology to a given sequence. In this procedure, a lambda library is screened using a specially designed plasmid carrying the desired target sequence. Recombinants arising from cross-over events between the plasmid and a bacteriophage carrying a corresponding region of homology are selected by their ability to grow on strain DM21. Growth of lambda on DM21 requires the presence of an allele encoded on the plasmid to suppress an amber mutation in the host strain that prevents lambda propagation. Recovery of the original phage carrying the target sequence requires a reversal of the homologous recombination event. This reversal occurs spontaneously, and is detected by PCR amplification using primers that flank the cloning site in the lambda vector.
Scene characterization using sub-aperture polarimetric interferometric SAR data (2004)

In this paper, a fully polarimetric analysis method is introduced to decompose synthesized interferometric SAR images into sub-aperture data sets, which correspond to the scene responses under different azimuthal look-angles. A statistical analysis of polarimetric parameters permits to clearly discriminate media showing a nonstationary polarimetric behavior during the SAR integration. A method is proposed to observe the polarimetric interferometric properties of anisotropic targets.
Recombination rate coefficients for astrophysical applications from storage-ring experiments (2002)

The basic approach for measuring electron-ion recombination rate coefficients in merged-beams electron-ion collision experiments at heavy-ion storage rings is outlined. As an example experimental results for the low temperature recombination of C IV ions are compared with the recommended theoretical rate coefficient by Mazzotta et al. The latter deviates by factors of up to 5 from the experimental one.
Novel Centroid Localization Algorithm for Three-Dimensional Wireless Sensor Networks (2008)

In this paper, we propose a new localization algorithm which can be effectively used in three-dimensional (3D) wireless sensor networks. This scheme needs no additional hardware support and can be implemented in a distributed way. The proposed method can improve the location accuracy with relatively low communication traffic and computing complexity. Simulation results show that the performance of the proposed algorithm is superior to that of the conventional centroid algorithm.
Emerging Technologies of Polymeric Nanoparticles in Cancer Drug Delivery (2010)

Polymeric nanomaterials have the potential to improve upon present chemotherapy delivery methods. They successfully reduce side effects while increasing dosage, increase residence time in the body, offer a sustained and tunable release, and have the ability to deliver multiple drugs in one carrier. However, traditional nanomaterial formulations have not produced highly therapeutic formulations to date due to their passive delivery methods and lack of rapid drug release at their intended site. In this paper, we have focused on a few “smart” technologies that further enhance the benefits of typical nanomaterials. Temperature and pH-responsive drug delivery devices were reviewed as methods for triggering release of encapsulating drugs, while aptamer and ligand conjugation were discussed as methods for targeted and intracellular delivery, with emphases on in vitro and in vivo works for each method.
Quantum state sensitivity to initial conditions (1998)

The different time-dependent distances of two arbitrarily close quantum or classical-statistical states to a third fixed state are shown to imply an experimentally relevant notion of state sensitivity to initial conditions. A quantitative classification scheme of quantum states by their sensitivity and instability in state space is given that reduces to the one performed by classical-mechanical Lyapunov exponents in the classical limit
Clinical Value of Morphometric and DNA Flow Cytometric Variables as Independent Predictors of Survival in Epithelial Ovarian Carcinoma: A 5-year Follow-up Study (2009)

The aim of this follow-up study is to validate the clinical significance of quantitative morphometric and DNA flow cytometric variables as independent prognostic factors of overall survival and progression-free survival in epithelial ovarian carcinoma. Tumor samples were collected from 135 patients with epithelial ovarian carcinoma at 3 hospitals in the Netherlands. Evaluated clinico-pathologic variables were age, histologic subtype, differentiation grade, clinical stage [International Federation of Gynecology and Obstetrics (FIGO)], presence of ascites, serum CA-125, and the completeness of debulking surgery. Morphometry and DNA flow cytometric techniques were assessed on each tumor sample to determine the mitotic activity index (MAI), volume percentage epithelium, mean nuclear area (MNA), standard deviation of MNA (SD MNA), nuclear perimeter (NP), and DNA ploidy. Univariate analysis showed that differentiation grade, FIGO stage, presence of ascites, preoperative CA-125 levels, DNA ploidy, and MAI, NP, and MNA were of significant prognostic value. After multivariate analysis (using forward Cox proportional hazard analysis), only differentiation grade and FIGO stage remained significant. From this study, we can conclude that morphometry and DNA flow cytometry are not independent prognosticators and therefore have no clinical value in predicting prognosis in ovarian carcinoma.
Enzyme formation and polysaccharide synthesis by bacteria. II (1936)

AN account was given in a previous communication [Cooper and Preston, 1935] of the study of the biochemical conditions influencing the formation and activity of diastase and invertase in bacteria, and also of the synthesising enzyme associated with the formation of polysaccharides of the "laevan" type by bacterial action.It was suggested in that paper that the investigations would be of wider physiological interest if they could be extended to the formation of other polysaccharides such as dextrans, galactans, pentosans, in addition to laevans.Experiments in this direction were commenced with numerous microorganisms, but in the case of the aerobic sporing bacilli and the plant-pathogenic bacteria their synthetic capacity was limited to "laevan formation".Further investigations with other micro-organisms have now been carried out and are described in the present paper.The general experimental methods and basal culture media employed were the same as those used in the previous work, the principal culture medium being a solution of % Peptone 0-1 Na2HPO4, 12H20
Cytokine and Eicosanoid Production by Cultured Human Monocytes Exposed to Titanium Particulate Debris (1999)

: Phagocytosis of particulate wear debris from arthroplasties by macrophages induces an inflammatory response that has been linked to implant loosening and premature failure of artificial joints. Inflammatory mediators released by phagocytic macrophages such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), and prostaglandin E(2) (PGE(2)) are believed to play a central role in the pathogenesis of aseptic loosening. The objective of this study was to characterize titanium alloy particulates that closely match wear debris found around joint arthroplasties and to study their effects on the biosynthesis of inflammatory mediators by cultured monocytes. Peripheral blood monocytes were isolated from healthy human volunteers. Monocytes were cultured in 96-well plates for 24 h, washed, and exposed to three concentrations of titanium particulates and controls from 18-24 h. Supernatants were assayed for TNF-alpha, IL-1beta, IL-6, and PGE(2) activity. Energy dispersive X-ray spectroscopy (EDX) verified the titanium alloy to be Ti6A14V. Scanning electron microscopy (SEM) analysis showed significant titanium particulate heterogeneity with approximately 95% of the particles <1 µm in diameter. SEM and EDX technology was useful in the characterization of the titanium particulates utilized for in vitro models of titanium-induced cytokine release by monocytes. Incubation of titanium particulates (in concentrations similar to those found around loosened prosthetic joints) with cultured monocytes significantly increased their production of TNF-alpha, IL-1beta, and PGE(2).
On full-view coverage in camera sensor networks (2011)

Camera sensors are different from traditional scalar sensors as different cameras from different positions can form distinct views of the object. However, traditional disk sensing model does not consider this intrinsic property of camera sensors. To this end, we propose a novel model called full-view coverage. An object is considered to be full-view covered if for any direction from 0 to 2π (object's facing direction), there is always a sensor such that the object is within the sensor's range and more importantly the sensor's viewing direction is sufficiently close to the object's facing direction. With this model, we propose an efficient method for full-view coverage detection in any given camera sensor networks. We also derive a sufficient condition on the sensor density needed for full-view coverage in a random uniform deployment. Finally, we show a necessary and sufficient condition on the sensor density for full-view coverage in a triangular lattice based deployment.
Generalized Inverses, Ridge Regression, Biased Linear Estimation, and Nonlinear Estimation (1970)

A principal objective of this paper is to discuss a class of biased linear estimators employing generalized inverses. A second objective is to establish a unifying perspective. The paper exhibits theoretical properties shared by generalized inverse estimators, ridge estimators, and corresponding nonlinear estimation procedures. From this perspective it becomes clear why all these methods work so well in practical estimation from nonorthogonal data.
An allelic series at the KARRIKIN INSENSITIVE 2 locus of Arabidopsis thaliana decouples ligand hydrolysis and receptor degradation from downstream signalling (2018)

Karrikins are butenolide compounds present in post-fire environments that can stimulate seed germination in many species, including Arabidopsis thaliana. Plants also produce endogenous butenolide compounds that serve as hormones, namely strigolactones (SLs). The receptor for karrikins (KARRIKIN INSENSITIVE 2; KAI2) and the receptor for SLs (DWARF14; D14) are homologous proteins that share many similarities. The mode of action of D14 as a dual enzyme receptor protein is well established, but the nature of KAI2-dependent signalling and its function as a receptor are not fully understood. To expand our knowledge of how KAI2 operates, we screened ethyl methanesulphonate (EMS)-mutagenized populations of A. thaliana for mutants with kai2-like phenotypes and isolated 13 new kai2 alleles. Among these alleles, kai2-10 encoded a D184N protein variant that was stable in planta. Differential scanning fluorimetry assays indicated that the KAI2 D184N protein could interact normally with bioactive ligands. We developed a KAI2-active version of the fluorescent strigolactone analogue Yoshimulactone Green to show that KAI2 D184N exhibits normal rates of ligand hydrolysis. KAI2 D184N degraded in response to treatment with exogenous ligands, suggesting that receptor degradation is a consequence of ligand binding and hydrolysis, but is insufficient for signalling activity. Remarkably, KAI2 D184N degradation was hypersensitive to karrikins, but showed a normal response to strigolactone analogues, implying that these butenolides may interact differently with KAI2. These results demonstrate that the enzymatic and signalling functions of KAI2 can be decoupled, and provide important insights into the mechanistic events that underpin butenolide signalling in plants.
United States Patent: Lime Feeding Repellent (1998)

Transgender AYA consider numerous factors in deciding whether to pursue FP. Although individual desires for and family values around biological parenthood influenced whether AYA pursued specialized FP counseling, individual experiences of gender dysphoria and costs of FP were barriers. AYA also identified shortcomings in fertility counseling with providers, highlighting the need to establish standardized counseling protocols and develop patient decision aids.
