Galaxy and mass assembly: Redshift space distortions from the clipped galaxy field (2016)

We present the first cosmological measurement derived from a galaxy density field subject to a ``clipping'' transformation. By enforcing an upper bound on the galaxy number density field in the galaxy and mass assembly survey (GAMA), contributions from the nonlinear processes of virialization and galaxy bias are greatly reduced. This leads to a galaxy power spectrum which is easier to model, without calibration from numerical simulations. We develop a theoretical model for the power spectrum of a clipped field in redshift space, which is exact for the case of anisotropic Gaussian fields. Clipping is found to extend the applicability of the conventional Kaiser prescription by more than a factor of 3 in wave numbers, or a factor of 30 in terms of the number of Fourier modes. By modeling the galaxy power spectrum on scales $k&lt;0.3\text{ }\text{ }h{\mathrm{Mpc}}^{\ensuremath{-}1}$ and density fluctuations ${\ensuremath{\delta}}_{g}&lt;4$ we measure the normalized growth rate $f{\ensuremath{\sigma}}_{8}(z=0.18)=0.29\ifmmode\pm\else\textpm\fi{}0.10$.
Integrating molecular switching and chemical reactivity using photoresponsive hexatrienes (2006)

Abstract The use of photoresponsive hexatriene architectures to regulate chemical reactivity is described. The major focus of this report is how the two isomers of dithienylethene derivatives exhibit different steric and electronic properties. The ring-open form is structurally flexible, and the thiophene rings are electronically insulated from each other, while the ring-closed counterpart has a rigid structure, and there is a linear π-conjugated pathway along the molecular backbone. Representative examples that demonstrate how these photoswitches can be used to influence metal coordination, catalysis, and nucleophilicity are highlighted in this overview.
Acute or chronic lithium does not affect agonist-stimulated inositol trisphosphate formation in rat brain in vivo (1996)

Rats were given lithium either acutely by s.c. injection (4 m eq kg-1) or chronically by including 0.2% LiCl in their diet for 3 weeks. Microdialysis probes were inserted into the cortex or hippocampus, using re-usable guides, and perfused with artificial CSF. Fractions were collected beginning 18 h after the end of treatment and were analysed for inositol trisphosphate (IP3). Neither acute nor chronic treatment affected basal levels of IP3 or stimulation of IP3 formation by either carbachol or noradrenaline in the hippocampus. Similarly, neither basal nor carbachol-stimulated IP3 levels in rat cortex were affected by acute Li administration. It would appear that the reductions in these parameters previously reported by other workers using brain slices were due to inositol depletion occurring at the stage of brain slice preparation. The inositol depletion hypothesis for the mechanism of action of lithium does not therefore appear to be supported by in vivo evidence.
Non-uniformité de la distribution spatiale des états de surface dans le canal des transistors CMOS (1988)

Nous avons montré que les densités moyennes d'états d'interface obtenues par la technique de pompage de charge peuvent conduire à une surestimation du nombre réel de ces défauts en milieu de canal des transistors MOS, lorsque l'on suppose qu'ils sont uniformément distribués sur toute l'étendue de l'interface Si-SiO2. Les densités d'états de surface peuvent être plus élevées près de la source et du drain, même lorsque le transistor MOS n'a pas été soumis à une contrainte de vieillissement. Nous suggérons que cette augmentation est due aux dommages inévitablement produits au cours de certaines étapes du procédé d'élaboration des transistors et en particulier lors de la gravure plasma de l'électrode de grille. Les densités locales des états de surface doivent alors nécessairement être prises en compte, lors des études de vieillissement sur de tels composants. Nous proposons une nouvelle méthode de calcul permettant d'accéder, à partir des mesures en pompage de charge, à la densité d'états d'interface à proximité de la source et du drain avant et après injection de porteurs chauds.
Influence of Pass Sequence on Cross–Rolling Textures in Armco–Iron (1991)

The textures of different modes of “balanced” cross‐rolling were studied in ARMCO‐iron. Thereby equal partial rolling degrees are applied in longitudinal and transverse direction. Three modes of cross‐rolling were used. In true multi‐stage cross‐rolling the rolling direction is changed by 90° after each small deformation pass. In two‐stage rolling at first all longitudinal passes were done and then all transversal passes. In four‐stage rolling four alternate groups of longitudinal and transversal passes were used. The main texture component is {001}‹110› the density of which increases from two‐stage to multi‐stage. A second coeponent is a ‹111› || ND fibre and finally a minor cube component is observed.

Placental and endothelial biomarkers for the prediction of superimposed pre-eclampsia in chronic kidney disease (2021)

Increased surveillance for the need for delivery should take place in women with CKD and plasma PlGF below 150 pg/ml after 20 weeks' gestation, with awareness that predictive value is reduced as excretory kidney function declines. Maternal endothelial dysfunction may alter the PlGF threshold at which superimposed pre-eclampsia manifests in women with CKD.
Online power meter calibration for accurate cyclist power control (2018)

This paper deals with cyclist power estimation in bicycles via a power meter device measuring the torque applied to the pedal. In order to guarantee the correctness of power estimation, it can be shown that the angular displacement between the crank arm longitudinal axis and the torque measurement axis must be accurately known. In this work, an online algorithm is developed to estimate such an angle, which can also vary along the time due to mechanical stress, without the need of a periodic calibration procedure. All these features make the resulting power estimation suitable for real-time cyclist power control. Experimental results show the effectiveness of the proposed estimation procedure on real road tests.
Optical flow: a curve evolution approach (1996)

A novel approach for the computation of optical flow based on an L (1) type minimization is presented. It is shown that the approach has inherent advantages since it does not smooth the flow-velocity across the edges and hence preserves edge information. A numerical approach based on computation of evolving curves is proposed for computing the optical flow field. Computations are carried out on a number of real image sequences in order to illustrate the theory as well as the numerical approach.
Informal caregivers’ attitudes and compliance towards a connected health platform for home care support: Insights from a long-term exposure (2019)

Background: When designing Connected Health (CH) solutions for home care, it is vital to focus on usability and user experience to ensure that technologies are easy to use and meet users’ expectations and needs. Generally, the usability and user experience tests are conducted during short-term exposure, which does not allow a true understanding of how the technology can help with the home caring tasks. Research aim: We aim to investigate informal caregivers’ feedback on the utility and usability of a CH monitoring platform for People with Dementia (PwD) during a period of extended use in the natural living context, and to understand how this was related to compliance patterns. Methods: Informal caregiver’s feedback about the CH platform, usability, and the impact of short-term versus long-term exposure were investigated through semi-structured individual interviews at the beginning and end of a 6-month deployment in the home care setting. Informal caregivers’ compliance with the CH platform was analysed from their daily platform utilization during the deployment time. Results: 11 informal caregivers agreed to participate. There was a change in the participants’ opinions about the CH platform between the short-term and the long-term exposure feedback. Their initial impressions about what the CH platform could offer them to improve their delivery of home care for the PwD did not correspond with what they found that the CH platform could provide them following the long-term exposure. If at the beginning they saw the CH platform as a helpful tool to facilitate home care delivery and to improve their self-efficacy, after the deployment they expressed that because of the way the platform was designed it was mainly conceived for dementia research benefit and not to fulfill their caring needs. Compliance with the CH platform was quite low and similar between all participants. Conclusions: Most contemporary CH studies are not conducted in real-life settings and without enough duration in time. Consequently, this is not providing accurate insights into the factual informal caregivers’ interaction with these technologies and their suitability for their caring needs and support. With this study, we have recognized the importance of studying how informal caregivers’ are engaging with CH for home care in their own environments and for enough duration of time. We have also highlighted that, despite the fact of applying UCD, the result may not always be satisfactory for the user. For these reasons, more longitudinal research on PwD and their informal caregivers, CH technologies adoption need to be conducted.
Corrosion of carbon steel and 18% Cr-8% Ni stainless steels in 23% by weight fluorosilicic acid and 10-30-0 suspension fertilizer with fluorosilicic acid added. (1990)

Research studies conducted by the Tennessee Valley Authority (TVA) have shown that addition of fluorosilicic acid can improve the physical properties of suspension fertilizers made from monoammonium phosphate (MAP) containing metallic impurities. The experimental data showed that addition of as little as 0.6% fluorine as fluorosilicic acid to a 10-30-0 grade suspension improved its viscosity, pourability, and high-temperature storage and increased the water solubility of the nitrogen and P2O5. Because fluorosilicic acid is very corrosive in nature, a series of electrochemical and immersion corrosion tests was conducted to study the effect of fluorosilicic acid on the corrosiveness of 10-30-0 suspension containing fluorosilicic acid. The corrosion tests included exposure of mild steel and several popular austenitic stainless steels under static conditions at both ambient temperature and 130°F. Tests were also made with the corrosion test specimens exposed in fluorosilicic acid (23% by wt). This paper includes results of these corrosion tests.
A Flexible Reformulation of the Refueling Station Location Problem (2012)

Serious environmental and economic problems of using fossil fuels in transportation sections force managers to think of alternative fuels such as hydrogen, ethanol, biodiesel, natural gas, or electricity. Meanwhile, lack of fuel network infrastructures is a major problem, which needs to be investigated considering the number and optimal location of alternative fuel stations. In the literature, two different flow-based demand modeling concepts (the maximum cover and set cover) have been proposed for solving this problem. Because of the huge number of combinations of fuel stations for covering the flow of each path, the models are impractical for the real size problems. In this paper, the flow refueling location model was reformulated and a flexible mixed-integer linear programming model was presented, which was able to obtain an optimal solution much faster than the previous set cover version. The model also could be solved in the maximum cover form in a reasonable time on the large-sized networks.
Coincident basophilic chronic myelogenous leukemia and pulmonary tuberculosis. Associated with extreme elevations of blood histamine levels and maturity onset asthma (1968)

A case of coincident basophilic chronic myelogenous leukemia and pulmonary tuberculosis is reported. Marked elevations in serum histamine levels were associated with maturity onset-bronchial asthma which was controlled with antihistamine medication. The diagnosis of tuberculosis was established by pleural fluid cultures. The diagnosis of chronic myelogenous leukemia was established by determination of leukocyte alkaline phosphatase levels and chromosome studies. The importance of such studies in cases of tuberculosis with leukemoid reactions is stressed.
Synthesis of Triazolyl-Oxadiazolyl-Thiazolyl- and Thiadiazolylbenzofuran of Potential Biological Activity (2002)

4,7-Dimethoxy ( Ia ) and 4-methoxy ( Ib ) 6-hydroxybenzofuran-5-carbohydrazide were reacted with aryl or alkyl isothiocyanates to give the corresponding thiosemicarbazides ( IIa-h ). Cyclization of the substituted thiosemicarbazides with sodium hydroxide led to the formation of 1,3,4-triazol-2-yl-benzofuran derivatives ( IIIa-d ). Desulfurization of thiosemicarbazide by mercuric oxide gave 1,3,4-oxadiazolyl-benzofuran ( IVa-c ). Treatment of thiosemicarbazide with ethyl bromo-acetate or f -bromopropionic acid yielded 4-thiazolidin-2-yl-carbonyl-benzofuran ( Va-h ). The reaction of compounds IIb , e , f with sulphuric acid or phosphorus oxychloride gave 1,3,4-thiadiazol-2-yl-benzofuran ( VIa-d , VII ).
Self-Supervised ECG Representation Learning for Emotion Recognition (2020)

We exploit a self-supervised deep multi-task learning framework for electrocardiogram (ECG) -based emotion recognition. The proposed solution consists of two stages of learning <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a)</i> learning ECG representations and <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">b)</i> learning to classify emotions. ECG representations are learned by a signal transformation recognition network. The network learns high-level abstract representations from unlabeled ECG data. Six different signal transformations are applied to the ECG signals, and transformation recognition is performed as pretext tasks. Training the model on pretext tasks helps the network learn spatiotemporal representations that generalize well across different datasets and different emotion categories. We transfer the weights of the self-supervised network to an emotion recognition network, where the convolutional layers are kept frozen and the dense layers are trained with labelled ECG data. We show that the proposed solution considerably improves the performance compared to a network trained using fully-supervised learning. New state-of-the-art results are set in classification of arousal, valence, affective states, and stress for the four utilized datasets. Extensive experiments are performed, providing interesting insights into the impact of using a multi-task self-supervised structure instead of a single-task model, as well as the optimum level of difficulty required for the pretext self-supervised tasks.
Crucial Factors in the Origins of Word-Meaning (2002)

Abstract We have been conducting large-scale public experiments with artificial robotic agents to explore what the necessary and sufficient prerequisites are for word-meaning pairs to evolve autonomously in a population of agents through a self-organized process. We focus not so much on the question of why language has evolved, but rather on how. There are many good reasons to use language once it has come into existence; for example, for establishing and maintaining group coherence, for transmission of cultural knowledge such as tool use, etc. But these reasons only explain why verbal behaviour is reinforced. They do not explain how this verbal behaviour might emerge or become complex. Our hypothesis is that when agents engage in particular interactive behaviours that in turn require specific cognitive structures, they automatically arrive at a language system. This interactive behaviour should be a natural outgrowth of co-operative behaviour (if this were not the case, the behaviour would be unlikely to emerge),
Respiratory Motion Compensation for Simultaneous PET/MR based on strongly undersampled radial MR data (2015)

We propose a new method for PET/MR respiratory motion compensation, which is based on strongly undersampled measured MR data and a) runs in parallel with the PET acquisition, b) can be interlaced with clinical MR sequences, and c) can be acquired with measurement times as short as 0.5 min per bed position. An MR dataset covering the free-breathing thorax and abdomen of a volunteer was acquired with a Siemens Biograph mMR system. We applied a 3D encoded radial stack-of- stars sequence with a golden angle radial spacing (acquisition time: 5.0 min). Respiratory motion amplitudes were estimated from measured k-space centers allowing for a retrospective gating into 20 overlapping motion phase bins with a width of 10%. In addition, two highly undersampled datasets consisting of 300 and 600 spokes were created corresponding to acquisition times of 0.5 min and 1.0 min, respectively. 4D gated MR images of the three datasets (0.5, 1.0 and 5.0 min acquisition time) were reconstructed iteratively. For each of the three resulting image sets, MVFs were estimated. A 4D PET volume of the volunteer with four artificial hot lesions in the lungs and abdomen was simulated. 3D PET and MoCo 4D PET images based on the three sets of motion vector fields derived from MR were reconstructed and compared to a reference gated 4D reconstruction with ten-fold acquisition time. Visual inspection of the reconstructed PET images showed that blurring was reduced in MoCo 4D images for all acquisition times compared to the 3D reconstruction. A quantitative evaluation in the end-exhale and a mid-ventilation motion phase demonstrated that MoCo 4D reconstructions outperformed the 3D reconstruction in terms of SUVmean values for all lesions and acquisition times compared to the reference gated 4D reconstruction.
Haptoglobin Type and 30-Day Mortality in Diabetic Individuals Presenting With Acute Myocardial Infarction (2003)

There are two major classes of alleles for the haptoglobin (Hp) gene, denoted 1 and 2 (1). We have recently reported evidence that Hp is a major susceptibility gene for cardiovascular disease in the diabetic state (2,3). Moreover, we have provided a mechanism for this differential susceptibility conferred by the Hp type by demonstrating striking differences in the antioxidant protection afforded by the protein products of the different …
Compounds with Positive Inotropic Activity, III1):Synthesis of 4‐Aminoquinoline Derivatives as Potential Positive Inotropic Agents (1990)

Anilinoacrylic acid derivatives 2-4 are the key intermediates from which 1-alkyl substituted 4-aminoquinoline 10-15 as well as 4-alkylaminoquinoline derivatives 16-23 are synthesized and examined for positive inotropic activity on isolated left atria and papillary muscles from guinea-pig. Structure activity relationships indicate that the effect depends on the alkyl side chain of the target compounds.
UCR INTELLISHARE (2003)

In 1992, the University of California, Riverside's College of Engineering established a Center for Environmental Research and Technology (CE-CERT). The research center's mission is to be a recognized leader in environmental education, collaborate with industry and government, create new technology, and be a major contributor in improving our understanding of the environment. There are three primary laboratories at CE-CERT dealing with: 1) emissions and fuels research; 2) environmental policy, atmospheric processes, and air quality modeling; and 3) transportation systems and vehicle technology research. This paper provides a brief background on these research laboratories. In addition, focus is placed on a particular transportation systems research program at CE-CERT: the development and operation of an intelligent shared electric vehicle testbed that operates on and around the UCR campus, called UCR IntelliShare. This program has been operational for nearly three years and has provided a wealth of data on various aspects of shared vehicle systems such as operational strategies, carsharing technology, user behavior, and how these type of systems can impact society as a whole. In this paper, the operation of the system is described in detail, along with a description of the latest results.
Oncoplacental protein SP1--a constitutive and inducible late differentiation marker of the human myelomonocytic lineage (1987)

The oncoplacental protein SP1 is found in large quantities in human placenta, amniotic fluid, and pregnancy serum. Low levels have been reported in association with malignancy but also in healthy nonpregnant individuals. By indirect immunofluorescence, fluorescence-activated cell sorting, and immunoprecipitation we here demonstrate the presence of SP1 both on the surface and in the cytoplasm of human granulocytes but not in earlier myeloid progenitor cells in bone marrow. Lymphocytes did not contain the protein, and only trace amounts could be found in the cytoplasm of blood monocytes. A major glycoprotein with an apparent mol wt of 90,000 was obtained by immunoprecipitation of surface-labeled granulocytes. Cultivated blood monocytes, while adhering to surfaces or forming multinuclear giant cells, displayed a strong membrane and cytoplasmic expression of SP1. Treatment of the myeloid leukemia cell line ML-2 with tetraphorbol acetate (TPA) strongly induced SP1 in the membrane and cytoplasm as revealed by immunofluorescence and polyacrylamide gel electrophoresis (PAGE) of immunoprecipitates from lysates of surface radiolabeled cells. The induction of synthesis of SP1 in TPA-treated cells was confirmed by immunoprecipitation from lysates of cells metabolically labeled with 35S-methionine. Human lymphoblastoid and erythroleukemic cell lines did not express SP1 either before or after induced differentiation. Thus SP1 provides a late differentiation marker for the myelomonocytic lineage and is strongly induced during macrophage differentiation or by TPA treatment of ML-2 cells.
Plasmodium falciparum Kelch13 and its artemisinin‐resistant mutants assemble as hexamers in solution: a SAXS data‐driven modelling study (2022)

The artemisinin-resistant mutations in Plasmodium falciparum (PfKelch13) identified worldwide are mostly confined to the Broad-complex, tramtrack and bric-à-brac/poxvirus and zinc-finger (BTB/POZ) and Kelch-repeat propeller (KRP) domains. To date, only two crystal structures of the BTB/POZ-KRP domains as tight dimers are available, which limits structure-based predictions and interpretation of its role(s) in inducing clinical artemisinin resistance. Our solution Small-Angle X-ray Scattering (SAXS) data analysis and shape restoration brought forth that: (a) PfKelch13 forms a stable hexamer in P6 symmetry, (b) interactions of the N-termini drive the hexameric assembly, and (c) the six KRP domains project independently in space, forming a cauldron-like architecture. We further deduce that the artemisinin-sensitive mutant A578S is packed like the wild-type protein, however, hexameric assemblies of the predominant artemisinin-resistant mutants R539T and C580Y displayed detectable differences in the spatial positioning of their BTB/POZ-KRP domains. Lastly, mapping of mutations known to enable artemisinin resistance suggested evolutionary pressure in the selection for mutations in the BTB/POZ-KRP domains. These mutations appear non-detrimental to the hexameric assembly of proteins, and yet somehow alter the flux of downstream events essential for the susceptibility to artemisinin.
