α‐SiAlON Ceramics Obtained by Slip Casting and Pressureless Sintering (2003)

Dense α‐SiAlON ceramics were obtained by pressureless sintering of green compacts prepared using slip casting. The rheological properties of the reaction SiAlON suspension were optimized to achieve a high degree of dispersion with a high solids volume fraction, which resulted in homogeneous and relatively dense green bodies with high sintering ability, which could be densified by pressureless sintering at 1750°C for 2 h. The sintered samples revealed a high degree of uniformity and almost fully dense microstructures that consisted of many small, elongated grains homogeneously dispersed in the fracture surfaces, which had properties comparable with those of other SiAlONs obtained using hot pressing.
PbTe Colloidal Nanocrystals:  Synthesis, Characterization, and Multiple Exciton Generation (2006)

We report an alternative synthesis and the first optical characterization of colloidal PbTe nanocrystals (NCs). We have synthesized spherical PbTe NCs having a size distribution as low as 7%, ranging in diameter from 2.6 to 8.3 nm, with first exciton transitions tuned from 1009 to 2054 nm. The syntheses of colloidal cubic-like PbSe and PbTe NCs using a PbO "one-pot" approach are also reported. The photoluminescence quantum yield of PbTe spherical NCs was measured to be as high as 52 +/- 2%. We also report the first known observation of efficient multiple exciton generation (MEG) from single photons absorbed in PbTe NCs. Finally, we report calculated longitudinal and transverse Bohr radii for PbS, PbSe, and PbTe NCs to account for electronic band anisotropy. This is followed by a comparison of the differences in the electronic band structure and optical properties of these lead salts.
3T diffusion-weighted MRI of the thyroid gland with reduced distortion: preliminary results (2013)

DW imaging of the thyroid at 3T could potentially benefit from r-FOV acquisition strategies, such as the r-FOV DW EPI technique proposed in this paper.
Expression and chromosomal assignment of PTPH1 gene encoding a cytosolic protein tyrosine phosphatase homologous to cytoskeletal‐associated proteins (1993)

We have investigated the mRNA expression of 2 human protein tyrosine phosphatases with sequence homology to cytoskeletal proteins, PTPH1 and PTPMEG. Northern-blot analysis of PTPH1 using poly (A)+ RNA from normal human colon tissue showed a low-abundance message of 4.3 kb. Reverse-transcriptase/polymerase-chain reaction (RT-PCR) was therefore used to detect it in a wide variety of cell lines including 9 colorectal, 5 gastric, 5 hepatic and 6 hematopoietic tumor cells. PTPH1 mRNA was not detected only in Colo 320 cells over-expressing c-myc mRNA, among the colorectal cancer cell lines examined. When Colo 320 cells were incubated with 5 mM sodium butyrate for 5 days, PTPH1 mRNA became detectable, concomitant with the marked decrease in the expression level of c-myc mRNA. Moreover, the chromosomal localization of PTPH1 gene was investigated by fluorescence in situ hybridization. Interestingly, PTPH1 gene was mapped to 9q31 where the gene for Gorlin syndrome, a putative tumor suppressor gene, exists.
Posterior Urethral Valves: Inaccuracy of Prenatal Diagnosis (1998)

This study was undertaken to determine the specificity of prenatal diagnosis of posterior urethral valves. Twenty-two fetuses were diagnosed in utero with posterior urethral valves due to the presence of persistent megacystis and hydronephrosis. Ten cases had oligohydramnios and 12 had normal or increased fluid. Confirmation of diagnosis was not available in 3 fetuses. Only 8 of 19 fetuses had postnatal confirmation of posterior urethral valves. Other anomalies included urethral atresia, ureteral duplication, megacystis/megaureter, reflux and multicystic dysplastic kidney. We conclude that in utero evidence of megacystis and hydronephrosis with or without oligohydramnios is not diagnostic of posterior urethral valves.

Control strategy optimization of the hybrid electric bus based on remote self-learning driving cycles (2008)

In order to obtain the globally optimal solutions, Dynamic Programming ( DP ) technique have been investigated. But one major difficulty lies in the need of global /preview information about the trip to be made and the difficulty in obtaining the specific driving cycle for each trip. Another difficulty is the computational load for global optimization algorithms in the micro-processor inside the vehicle[18]. In this paper a new control scheme called control strategy optimization based on the remote self-learning driving cycles is presented.
HIV-infected individuals receiving effective antiviral therapy for extended periods of time continually replenish their viral reservoir (2005)

The persistence of latently infected, resting CD4+ T cells is considered to be a major obstacle in preventing the eradication of HIV-1 even in patients who have received effective antiviral therapy for an average duration of 5 years. Although previous studies have suggested that the latent HIV reservoir in the resting CD4+ T cell compartment is virologically quiescent in the absence of activating stimuli, evidence has been mounting to suggest that low levels of ongoing viral replication persist and in turn, prolong the overall half-life of HIV in patients receiving antiviral therapy. Here, we demonstrate the persistence of replication-competent virus in CD4+ T cells in a cohort of patients who had received uninterrupted antiviral therapy for up to 9.1 years that rendered them consistently aviremic throughout that time. Surprisingly, substantially higher levels of HIV proviral DNA were found in activated CD4+ T cells when compared with resting CD4+ T cells in the majority of patients we studied. Phylogenetic analyses revealed evidence for cross infection between the resting and activated CD4+ T cell compartments, suggesting that ongoing reactivation of latently infected, resting CD4+ T cells and spread of virus by activated CD4+ T cells may occur in these patients. Such events may allow continual replenishment of the CD4+ T cell reservoir and resetting of the half-life of the latently infected, resting CD4+ T cells despite prolonged periods of aviremia.
Hybrid Particle Swarm Optimization for Medical Image Registration (2009)

Medical image registration is an important issue. In registrations, we seek an estimate of the transformation that registers the reference image and test image by optimizing their metric function (similarity measure). To date, local optimization techniques, such as the gradient decent method, are frequently used for medical image registrations. But these methods need good initial values for estimation in order to avoid the local minimum. In this paper, we propose a new approach named hybrid particle swarm optimization (HPSO) for medical image registration, which incorporates two concepts (subpopulation and crossover) of genetic algorithms into the conventional PSO. Experimental results with medical volume phantom data show that the proposed HPSO performs much better results than conventional GA and PSO.
Evaluation of entity resolution approaches on real-world match problems (2010)

Despite the huge amount of recent research efforts on entity resolution (matching) there has not yet been a comparative evaluation on the relative effectiveness and efficiency of alternate approaches. We therefore present such an evaluation of existing implementations on challenging real-world match tasks. We consider approaches both with and without using machine learning to find suitable parameterization and combination of similarity functions. In addition to approaches from the research community we also consider a state-of-the-art commercial entity resolution implementation. Our results indicate significant quality and efficiency differences between different approaches. We also find that some challenging resolution tasks such as matching product entities from online shops are not sufficiently solved with conventional approaches based on the similarity of attribute values.
Forty-one near full-length HIV-1 sequences from Kenya reveal an epidemic of subtype A and A-containing recombinants (2002)

In Kenya, 93% of HIV-1 genomes were subtype A or A-containing recombinant strains. Almost 40% of all strains were recombinant. Vaccine candidates tested in Kenya should be based on subtype A strains, but the methods used for evaluation of breakthrough infections during future vaccine trials should be capable of identifying non-A subtypes, the A2 sub-subtype, and recombinants.
Printed Miscellanies in England, 1640–1682: “store-house[s] of wit.” (2012)

lot of people in seventeenth-century England had been reading The Academy of Complements.1 It went through at least twelve editions between 1640 and 1685, each one larger than last,2 and references to it in plays and poems suggest a well-known publication.3 To twentieth-century eyes, it is a curious text: a farrago of poetry, exemplary compliments, Complementall and amorous Letters, Questions with their answers resolving doubts of Lovers, instructions on addressing the King, or Queenes Majesty, and A Table for Vnderstanding of hard English words. It is a bunched, busy duodecimo, and in it, reader can find stock poetic eloquence, like Needmore's, tailored to suit his circumstances. For a Protestation of his obedi ence, text suggests I shall not all dayes of my life have a will, which shall not obey yours. To offer wooing praise, reader might try Sweet mouth that sendest a musicke rosied breath / Whose every word darts me a living death. And to make An offer of Service, or voice Expressions of Affections, or answer questions such as How must a man behave himselfe amongst Ladyes?, The Academy of Complements provides fittingly sugared words.4

Inhibition of the constitutive activity of human 5‐HT<sub>1A</sub> receptors by the inverse agonist, spiperone but not the neutral antagonist, WAY 100,635 (1997)

At recombinant human 5-hydroxytryptamine (5-HT)5-HT1A receptors expressed in Chinese hamster ovary cells (CHO-5-HT1A), 5-carboxamidotryptamine (5-CT), acted as a full agonist (relative to 5-HT = 100%) for stimulation of receptor-mediated [35S]-GTP gamma S (guanylyl 5'-[gamma-thio]-tryphosphate) binding. In contrast, spiperone inhibited basal [35S]-GTP gamma S binding by 30.2% (IC50 = 55.5 nM) in CHO-5-HT1A membranes but not in control untransfected membranes. The antagonist, N-[2-[4-(2-methoxyphenyl) -1-piperazinyl]ethyl]-N-(2-pyridinyl)-cyclohexane-carboxamide (WAY 100,635), blocked both 5-CT-induced stimulation and spiperone-induced inhibition of [35S]-GTP gamma S binding without itself modifying [35S]-GTP gamma S binding. It is concluded that, in this heterologous expression system, 5-HT1A receptors display 'constitutive' activation of G-proteins and that spiperone displays inverse agonist activity whereas WAY 100,635 acts as a 'neutral' antagonist at this site.
A Novel Method for Estimating Monocular Depth Using Cycle GAN and Segmentation (2020)

Modern image processing techniques use three-dimensional (3D) images, which contain spatial information such as depth and scale, in addition to visual information. These images are indispensable in virtual reality, augmented reality (AR), and autonomous driving applications. We propose a novel method to estimate monocular depth using a cycle generative adversarial network (GAN) and segmentation. In this paper, we propose a method for estimating depth information by combining segmentation. It uses three processes: segmentation and depth estimation, adversarial loss calculations, and cycle consistency loss calculations. The cycle consistency loss calculation process evaluates the similarity of two images when they are restored to their original forms after being estimated separately from two adversarial losses. To evaluate the objective reliability of the proposed method, we compared our proposed method with other monocular depth estimation (MDE) methods using the NYU Depth Dataset V2. Our results show that the benchmark value for our proposed method is better than other methods. Therefore, we demonstrated that our proposed method is more efficient in determining depth estimation.
Synthesis of indazol‐4,7‐dione derivatives as potential trypanocidal agents (2002)

Abstract The synthesis of new indazol‐4,7‐dione derivatives via 1,3‐dipolar cycloaddition of diazomethane with 2,3‐dimethyl‐1,4‐benzoquinone ( 2 ) and 1,4‐naphthoquinone ( 7 ) followed by N ‐alkylation of the pyrazol nitrogen atom of the corresponding quinones ( 3 ) and ( 8 ) with methyl chloroacetate is described. A series of amides from esters ( 5 ) and ( 10 ) were also obtained. These compounds were tested in vitro as potential anti‐trypanosomal agents. Compounds ( 4 ) and ( 8 ) were found to have significant activity.
Nickel Hyperaccumulation Defends Streptanthus polygaloides (Brassicaceae) Against Pathogens (1994)

The Ni-hyperaccumulating annual, Streptanthus polygaloides, may contain as much as 16,400 ppm Ni (dry weight) in its tissues. The function of Ni hyperaccumulation is not known. We tested the hypothesis that one function of Ni hyperaccumulation in S. polygaloides is defense against pathogens. Growth of pathogenic organisms on Ni-hyperaccumulating plants (averaging 5,630 ppm Ni, produced by growing plants on high-Ni soil) was compared to pathogen growth on nonhyper-accumulating plants (averaging 124 ppm Ni, produced by growing plants on low-Ni soil). Plants containing hyperaccumulated Ni were more slowly infected by a powdery mildew (Erysiphe polygoni) than low-Ni plants. Two strains of the bacterial pathogen Xanthomonas campestris pv. campestris (one a genetically engineered bioluminescent strain) grew in low-Ni plants but not high-Ni plants. Growth of X. campestris pv. campestris was markedly inhibited by Ni concentrations of 400 ppm in artificial media. Growth of the fungus Alternaria brassicicola, which was necrotrophic on S. polygaloides, also was inhibited on high-Ni leaves relative to low-Ni leaves. These results demonstrated negative effects of hyperaccumulated Ni on a taxonomically wide range of pathogenic organisms, supporting the hypothesis that Ni hyperaccumulation defends S. polygaloides against plant pathogens.
Syntheses of 4-[1-(2-deoxy-β-<scp>D</scp>-ribofuranosyl)]-derivatives of 2-substituted-5-fluoroaniline: "cytosine replacement" analogs of deoxycytidine for evaluation as anticancer and antihuman immunodeficiency virus (anti-HIV) agents (2000)

A group of 4-[1-(2-deoxy-β-D-ribofuranosyl)]-derivatives of 5-fluoroaniline possessing a variety of aryl C-2 substituents (6a R = H, 6b R = F, 6c R = Me) were synthesized. Accordingly, a Heck-type coupling reaction of the 4-iodoaniline derivatives (13ac) with the bis(tert-butyldimethylsilyl)glycal (11) in the presence of Pd(OAc) 2 and Ph 3 As, followed by removal of the tert-butyldimethylsilyl protection groups using n-Bu 4 N + F - , yielded the corresponding 4-(β-D-glycero-pentofuran-3-ulos-1-yl)aniline derivatives (14ac) having a C-3 C=O in the sugar ring. Reduction of the C-3 C=O compounds (14ac) using NaB(OAc) 3 H afforded the target 4-[1-(2-deoxy-β-D-ribofuranosyl)]-derivatives of the respective 2-substituted-5-fluoroaniline (6ac). The deoxycytidine mimic, 3-fluoro-4-[1-(2-deoxy-β-D-ribofuranosyl)]aniline (6a), in which the cytosine ring of deoxycytidine is replaced by a 4-(3-fluoroaniline) ring system, was inactive as an anticancer agent against a variety of tumor cell lines, and as an antihuman immunodeficiency virus (HIV-1, HIV-2) agent. The failure of this unnatural deoxycytidine mimic (6a) to exhibit anticancer-antiviral activity may be due to its inability to undergo phosphorylation by host cell- and virus-induced kinases.Key words: fluoroanilines, deoxycytidine mimics, anticancer-antihuman immunodeficiency virus (HIV) evaluation.
Wnt3a Growth Factor Induces Androgen Receptor-Mediated Transcription and Enhances Cell Growth in Human Prostate Cancer Cells (2004)

The Wnt signaling pathway plays a critical role in embryogenesis and tumorigenesis. However, biological roles of Wnt growth factors have not been fully characterized in prostate development and the pathogenesis of prostate cancer. In this study, we used Wnt3a-conditioned medium (Wnt3a-CM) and purified Wnt3a proteins to investigate whether there is a direct effect of Wnt3a on androgen receptor (AR)-mediated transcription and to determine its role in the growth of prostate cancer cells. We demonstrated that Wnt3a-CM either induces AR activity in the absence of androgens or enhances AR activity in the presence of low concentrations of androgens, whereas purified Wnt3a showed a pronounced effect in the presence of low concentrations of ligands. We also showed that Wnt3a-CM and the purified Wnt3a enhance the level of cytosolic and nuclear beta-catenin, suggesting an involvement of beta-catenin in this regulation. Moreover, treatment of LNCaP cells with Wnt3a-CM and purified Wnt3a significantly enhances cell growth in the absence of androgens. Our findings demonstrate that Wnt3a plays an important role in androgen-mediated transcription and cell growth. These results suggest a novel mechanism for the progression of prostate cancer.
Agent-Based Intelligent System Modeling (2009)

An intelligent system is a system that has, similar to a living organism, a coherent set of components and subsystems working together to engage in goal-driven activities. In general, an intelligent system is able to sense and respond to the changing environment; gather and store information in its memory; learn from earlier experiences; adapt its behaviors to meet new challenges; and achieve its pre-determined or evolving objectives. The system may start with a set of predefined stimulusresponse rules. Those rules may be revised and improved through learning. Anytime the system encounters a situation, it evaluates and selects the most appropriate rules from its memory to act upon. Most human organizations such as nations, governments, universities, and business firms, can be considered as intelligent systems. In recent years, researchers have developed frameworks for building organizations around intelligence, as opposed to traditional approaches that focus on products, processes, or functions (e.g., Liang, 2002; Gupta and Sharma, 2004). Today’s organizations must go beyond traditional goals of efficiency and effectiveness; they need to have organizational intelligence in order to adapt and survive in a continuously changing environment (Liebowitz, 1999). The intelligent behaviors of those organizations include monitoring of operations, listening and responding to stakeholders, watching the markets, gathering and analyzing data, creating and disseminating knowledge, learning, and effective decision making. Modeling intelligent systems has been a challenge for researchers. Intelligent systems, in particular, those involve multiple intelligent players, are complex systems where system dynamics does not follow clearly defined rules. Traditional system dynamics approaches or statistical modeling approaches rely on rather restrictive assumptions such as homogeneity of individuals in the system. Many complex systems have components or units which are also complex systems. This fact has significantly increased the difficulty of modeling intelligent systems. Agent-based modeling of complex systems such as ecological systems, stock market, and disaster recovery has recently garnered significant research interest from a wide spectrum of fields from politics, economics, sociology, mathematics, computer science, management, to information systems. Agent-based modeling is well suited for intelligent systems research as it offers a platform to study systems behavior based on individual actions and interactions. In the following, we present the concepts and illustrate how intelligent agents can be used in modeling intelligent systems. We start with basic concepts of intelligent agents. Then we define agent-based modeling (ABM) and discuss strengths and weaknesses of ABM. The next section applies ABM to intelligent system modeling. We use an example of technology diffusion for illustration. Research issues and directions are discussed next, followed by conclusions.
Nanoscale metal transistor control of Fowler–Nordheim tunneling currents through 16 nm insulating channel (1999)

A nanoscale metal/insulator tunnel transistor (MITT) with a channel length of only 16 nm is fabricated by conventional photolithography, and its operation is experimentally studied. The MITT consists of two metal electrodes, an insulating channel inserted laterally between these two electrodes, and a third metal gate electrode formed upon the gate insulator above the insulating channel. The Fowler–Nordheim tunneling currents flowing from one metal electrode to the other through the insulating channel are controlled by applying a voltage to the gate electrode. It is found that the MITT can be operated similarly to the semiconductor transistor, and the feasibility of the nanoscale metal transistor is demonstrated.
