Triplet-polaron quenching by charges on guest molecules in phosphorescent organic light emitting devices (2012)

We use delayed electroluminescence and photoluminescence measurements to study triplet-polaron-quenching (TPQ) mechanism in phosphorescent organic light emitting devices. Results show that the TPQ mechanism is mainly caused by charges within the bulk of the emission layer (EML) rather than by charges in the hole transport layer (HTL) or at the HTL/EML interface. Furthermore, charges on the guest rather than those on the host are found to be the most efficient in quenching excitons, revealing that guest polaronic species are the most detrimental to device efficiency. The results also show that direct injection of holes from the HTL into the guest material reduces device efficiency.
Cu x S back contact for CdTe solar cells (2003)

"Copper sulfide (CuxS) films were studied as a back contact material for CdTe solar cells. The CuxS films were made by chemical bathdeposition in aqueous solution. Annealing at 200±C in Ar improved the performance of the solar cells. Using the CdS/CdTe/CuxS/Cstructure, an open-circuit voltage (Voc) higher than 840 mV and an energy conversion efficiency higher than 11% were obtained."
Learning to Display High Dynamic Range Images (2004)

In this paper we present a novel method to map high dynamic range scenes to low dynamic range images for visualization. We formulate the problem as a quantization process and employ an adaptive learning strategy to ensure that the low dynamic range displays not only faithfully reproduce the original scenes but also are visually pleasing. This is achieved by the use of a competitive learning neural network that employs a frequency sensitive competitive learning mechanism. An L2 objective function ensures that the mapped low dynamic image preserves the relative visual contrast impressions of the original scene. A frequency sensitive competitive mechanism facilitates the full and even utilization of the limited displayable values. We present experimental results to demonstrate the effectiveness of the method in displaying a variety of high dynamic range scenes.

On Text Clustering with Side Information (2012)

Text clustering has become an increasingly important problem in recent years because of the tremendous amount of unstructured data which is available in various forms in online forums such as the web, social networks, and other information networks. In most cases, the data is not purely available in text form. A lot of side-information is available along with the text documents. Such side-information may be of different kinds, such as the links in the document, user-access behavior from web logs, or other non-textual attributes which are embedded into the text document. Such attributes may contain a tremendous amount of information for clustering purposes. However, the relative importance of this side-information may be difficult to estimate, especially when some of the information is noisy. In such cases, it can be risky to incorporate side-information into the clustering process, because it can either improve the quality of the representation for clustering, or can add noise to the process. Therefore, we need a principled way to perform the clustering process, so as to maximize the advantages from using this side information. In this paper, we design an algorithm which combines classical partitioning algorithms with probabilistic models in order to create an effective clustering approach. We present experimental results on a number of real data sets in order to illustrate the advantages of using such an approach.
S134014 Study on the tool wear characteristic in cutting of high carbon content type Co-Cr-Mo alloy (2012)

In this paper Study on the abrasion property of high carbon content tools of Co-Cr-Mo alloy. The Co-Cr-Mo alloys for medical use are highly corrosion resistant and abrasion resistant and have been used mostly for sliding parts of artificial joints. However, the work efficiency is quite low because it is extremely difficult to cut the alloys. To realize more efficient cutting works, we used a binder-less cBN tool in high-speed machining. We then found that high-precision, high-efficiency machining work could be performed.
Food‐bound B12 absorption and serum total homocysteine in patients with low serum B12 levels (1998)

This study was undertaken to determine whether measurements of serum total homocysteine (Hcys) and bound B12 absorption are useful in determining which patients with low- or low-normal levels of serum B12 are B12 deficient. In 40 patients with low or borderline serum levels of B12, food-bound B12 absorptions were determined using a body counter in an iron room, and were related to serum total Hcys levels. Food-bound B12 absorption was decreased in 16 patients and in an additional four, absorption of the free vitamin was also decreased. Homocysteine levels were elevated in four of the 16; in three of the four who had both decreased bound and free B12 absorptions, Hcys was elevated. If elevation of the Hcys level indicates tissue deficiency of B12, the 75% incidence of normal levels of Hcys in these patients with low food-bound B12 absorptions suggests the existence of a cohort of patients who may be at risk to develop, but have not yet developed, B12 deficiency. Only long term follow-up will reveal how many ultimately will become B12 deficient. Am. J. Hematol. 59:42–45, 1998. © 1998 Wiley-Liss, Inc.
RGB-D Based Detection of Texture-Less Planar Objects Applied to an AR Jigsaw Puzzle (2014)

This paper presents an Augmented Reality application that aims to help players to solve a jigsaw puzzle that consists of texture-less planar pieces with a discriminative shape. The pieces are detected using a technique based on RGB-D consumer devices, their poses are estimated, correctly assembled pieces are highlighted and additional information is rendered over each piece. A user study was conducted to evaluate the system, which demonstrated that players who used the application for solving the jigsaw puzzle obtained better results than the ones who did not use it.
Rough set-based proteochemometrics modeling of G-protein-coupled receptor-ligand (2006)

The large majority of the currently used drugs are small molecules that interact with proteins. Understanding protein-ligand recognition is thus central to drug discovery and design. Improved experimental techniques have resulted in an immense growth of drug target information. This has stimulated the development of chemogenomics and proteochemometrics (PCM) that take target information as well as ligand information into account to study the genomic effect of potential drugs. This thesis is concerned with modeling protein-ligand recognition, and the aim is to develop models that generalize to the entire protein-ligand space. To this end, protein-ligand interaction data has been extracted and manually curated from public databases, protein and ligand descriptors have been computed, and predictive models have been induced with machine-learning methods. An introduction to chemogenomics, machine learning, and PCM modeling is given in the thesis summary, which is followed by five research papers. Paper I shows that it is possible to induce interpretable models with a non-linear rule-based method, and paper II demonstrates that local descriptors of protein structure may be used to induce PCM models that cover proteins differing in sequence and fold. In paper III, such local descriptors are used to induce a PCM model on a large dataset that includes all major enzyme classes. This demonstrates that the local descriptors may be used to induce generalized models that span the entire known structural enzyme-ligand space. Paper IV describes a step towards proteome-wide PCM models, and shows that it is possible to predict high- and low-affinity complexes using a set of protein and ligand descriptors that do not require knowledge of 3D structure. Finally, paper V presents a method to visualize and compare protein-ligand chemogenomic subspaces, which may be used to predict unwanted cross-interactions of drugs with other proteins in the proteome.
A bidirectional dual-comb ring laser for simple and robust dual-comb spectroscopy (2015)

Fourier-transform spectroscopy is an indispensable tool for analyzing chemical samples in scientific research as well as chemical and pharmaceutical industries. Recently, its measurement speed, sensitivity, and precision have been shown to be significantly enhanced by using dual frequency combs. However, wide acceptance of this technique is hindered by its requirement for two frequency combs and active stabilization of the combs. Here we overcome this predicament with a Kerr-lens mode-locked bidirectional ring laser that generates two frequency combs with slightly different pulse repetition rates and a tunable yet highly stable rate difference. This peculiar lasing principle builds on a slight difference in optical cavity length between two counter-propagating lasing modes due to Kerr lensing. Since these combs are produced by the one and same laser cavity, their relative coherence stays passively stable without the need for active stabilization. To show its utility, we demonstrate broadband dual-comb spectroscopy with the single laser.

Risk factors for pre‐eclampsia in nulliparous and parous women: the Jerusalem Perinatal Study (2005)

Pre-eclampsia has been described as a 'disease of first pregnancies' and many believe that its occurrence in a later pregnancy signals a fundamentally different entity. We sought to compare risk factors in first and subsequent pregnancies. We studied 1319 cases of pre-eclampsia recorded in a historical cohort of 82,436 deliveries in Jerusalem in 1964-76. Logistic regression was used to control for covariates. The adjusted odds ratio (OR) for pre-eclampsia in first births was 2.58 (95% confidence interval[CI] 2.23, 2.97), compared with all later birth order groups, between which there were no detectable differences in risk. Other risk factors included increasing maternal age, diabetes (OR 5.64, 95% CI 4.33, 7.35), multiple gestations (OR 3.38, 95% CI 2.54, 4.49), fetal haemolytic disease (OR 2.24, 95% CI 1.43, 3.50) and lower maternal education. The risk of pre-eclampsia was not associated with the mother's employment outside the home and did not differ between immigrants vs. Israeli-born mothers or between groups of women whose fathers had been born in Western Asia, North Africa or Europe. Effects of each risk factor were similar within first and subsequent births. These results lend no support to the hypothesis that there is a fundamental difference between pre-eclampsia in a first pregnancy compared with that occurring in a later pregnancy; conclusions may be moderated, however, by the knowledge that the incidence of pre-eclampsia was low in this historical cohort.
Volume Change of Cement Plugs: Spotlight on the Role of Boundary Conditions Using an Improved Testing Method (2018)

Abstract Expansion additives have been used in cement plugs to mitigate the potential risk of plug failure resulting from shrinkage. These additives are effective only when their amount is tailored for downhole boundary conditions, and their role should be well understood. This work discusses using an improved testing method that enhances the dependability of the volume change measurement and exhibits the impact of test boundary conditions on the shrinking and expanding behaviors of cement plugs. Boundary conditions investigated with this method include temperature, pressure, water access to the cement from the formation, and the role of mechanical constraints. Dependability is demonstrated by verifying the repeatability and reproducibility of the method at two different laboratories. Together with the noninvasive continuous volume change, supplementary measurements, such as ultrasonic compressive strength, tensile strength, and chemical composition analysis, have provided inferences about the mechanism of volume change. The new method embodies all attributes listed in API 10 TR2 (1997), including a constant external stress state in all measurements and a constant pore pressure during total volume change measurement. The results of percentage volume change from this test method present an extremely small variance, highlighting its repeatability; additionally, the measurement was reproducible between laboratories. Expansion value increased with a decrease in confining pressure, and excessive expansion in the absence of an effective confining pressure produced weak samples. The absence of outside water caused cement containing the expansion aid to shrink more than its neat equivalent; such observations highlight the importance of fluid boundary on the action of expansion additives. These observations were possible because the test method can capture temporal and boundary condition effects more aptly. Thus, the improved method provides a dependable measurement for tailoring plug properties.
Innovative modulation schemes for future optical WDM transmission (2004)

In this paper, an overview of promising solutions for new modulation formats in optical WDM-transmission is presented and some recent results are summarized. We compare these formats with the standard conventional intensity modulation scheme. For real world applications it is necessary that these formats not only offer bandwidth reduction but also prove sufficient performance with respect to interference and intermodulation from adjacent channels, non-linear fibre properties, chromatic and polarization mode dispersion and noise resistance. Last but not least the implementation-effort at high speed must comply with economic constraints.

Transgenic perennial biofuel feedstocks and strategies for bioconfinement (2010)

The use of transgenic tools for the improvement of plant feedstocks will be required to realize the full economic and environmental benefits of cellulosic and other biofuels, particularly from perennial plants. Traits that are targets for improvement of biofuels crops include herbicide resistance, pest, drought, cold and salt tolerance, nutrient use efficiency, altered cell wall composition and improved processing and end-use characteristics. However, controlling gene flow is a major issue and there is no regulatory experience with perennial plants as dedicated biofuels feedstocks. Bioconfinement of transgenes is thus an obvious regulatory and biosafety objective to the release and commercialization of transgenic bioenergy feedstocks. In this article, we review bioconfinement strategies that target pollen or seeds that can be applied to perennial plants used as biofuels. These include male sterility, integration of transgenes into plastid genomes, removal of transgenes in pollen and seeds, transgene expression in vegetative organs for harvest before appearance of reproductive structures or gene use restriction technologies. © 2010 Future Science Ltd.
[Algebraic 2D PET image reconstruction using depth-of-interaction information] (2001)

Recently a high-performance PET scanner, which measures depth-of-interaction (DOI) information, is being developed for molecular imaging. DOI measurement of multi-layered thin crystals can improve spatial resolution and scanner sensitivity simultaneously. In this paper, we apply an algebraic image reconstruction method to 2-dimensional (2D) DOI-PET scanners using accurate system modeling, in order to evaluate the effects of using DOI information on PET image quality. Algebraic image reconstruction methods have been successfully used to improve PET image quality, compared with the conventional filtered backprojection method. The proposed method is applied to simulated data for a small 2D DOI-PET scanner. The results show that accurate system modeling improves spatial resolution without noise emphasis, and that DOI information improves uniformity of spatial resolution.
Exploiting retro oxa-Michael chemistry in polymers (2022)

One way to obtain recyclable polymeric materials is to include reversible bonds in polymers. Herein, we study the reversibility of the oxa-Michael reaction, explore its scope and limitations in simple model systems and further in linear polymers and polymer networks. Results show that for the retro oxa-Michael reactions of sulfone, acrylate or acrylonitrile based adducts elevated temperatures (> 100 °C) and Brønsted bases (e.g. KOH) are needed. Alcohols in oxa-Michael adducts can easily be exchanged within minutes. Further, oxa-Michael polymers can be depolymerized into small fragments in presence of alcohols and show self-healing characteristics in networks.
The finger 2 tip loop of Activin A is required for the formation of its non-signaling complex with ACVR1 and type II Bone Morphogenetic Protein receptors (2019)

Abstract Activin A functions in BMP signaling in two ways: it either engages ACVR1B to activate Smad2/3 signaling or binds ACVR1 to form a non-signaling complex (NSC). Although the former property has been studied extensively, the roles of the NSC remain unexplored. The genetic disorder fibrodysplasia ossificans progressiva (FOP) provides a unique window into ACVR1/Activin A signaling because in that disease Activin can either signal through FOP-mutant ACVR1 or form NSCs with wild type ACVR1. To explore the role of the NSC, we generated ‘agonist-only’ Activin A muteins that activate ACVR1B but cannot form the NSC with ACVR1. Using one of these muteins we demonstrate that failure to form the NSC in FOP results in more severe disease pathology. These results provide the first evidence for a biological role for the NSC in vivo and pave the way for further exploration of the NSC’s physiological role in corresponding knock-in mice. Impact Statement The non-signaling complex formed by Activin A and ACVR1 is operant in vivo and is required to temper the degree of heterotopic ossification in the genetic disorder fibrodysplasia ossificans progressiva.
