A Simple Repeat Sales House Price Index: Comparative Properties Under Alternative Data Generation Processes. (2010)

We propose a new method to estimate a repeat-sales house price index. Our unbalanced panel method employs an OLS panel regression to estimate the (log) house price as a function of time fixed effects and house-specific fixed effects. Comparisons are made across three repeat-sales methods using actual data, and using simulated data with both stationary and non-stationary relative price innovations. The unbalanced panel method comprehensively utilises all sale information on a house rather than splitting sales into distinct pairs. It is the simplest of the methods to implement, and possesses superior properties to the other two methods under a wide range of data generation processes.
Path-factors involving paths of order seven and nine (2015)

In this paper, we show the following two theorems (here $c_{i}(G-X)$ is the number of components $C$ of $G-X$ with $|V(C)|=i$): (i)~If a graph $G$ satisfies $c_{1}(G-X)+\frac{1}{3}c_{3}(G-X)+\frac{1}{3}c_{5}(G-X)\leq \frac{2}{3}|X|$ for all $X\subseteq V(G)$, then $G$ has a $\{P_{2},P_{7}\}$-factor. (ii)~If a graph $G$ satisfies $c_{1}(G-X)+c_{3}(G-X)+\frac{2}{3}c_{5}(G-X)+\frac{1}{3}c_{7}(G-X)\leq \frac{2}{3}|X|$ for all $X\subseteq V(G)$, then $G$ has a $\{P_{2},P_{9}\}$-factor.
A mobile tourism recommender system (2010)

Mobile tourist guides have been in the spotlight during the past decade resulting in many prototypes, either full-fledged standalone mobile applications or web-based applications. Particular emphasis has been given to personalisation of services, typically based on travel recommender systems used to assist tourists in choosing places to visit; these systems address an important aspect of personalization and hence reduce the information burden for the user. However, existing systems fail to exploit information, behaviors, ideas, evaluations, assessments, ratings, etc, by other tourists with similar interests, which provide ground for the cooperative production of tourist content and travel recommendations. In this paper we extend this notion of travel recommender systems utilizing collaborative filtering techniques for deriving improved recommendations. We also propose the use of Wireless Sensor Network (WSN) installations around tourist sites for providing mobile users convenient and inexpensive means for uploading tourist information and ratings about Points of Interest (POI) via their mobile devices. User ratings uploaded through WSN infrastructures are weighted higher to differentiate between users that rate POIs using the mobile tourist guide application in direct proximity of the POI and others using the Internet away from the POI.
Cytokine Comparisons Between Women With Breast Cancer and Women With a Negative Breast Biopsy (2008)

Levels of cytokines and their patterns were markedly different in women with breast cancer as compared with those in women who did not have breast cancer. Results from this study highlight the need for further research to examine the levels and patterns of cytokines that may serve as biomarkers in clinical research. Innovations in proteomic technology have implications for expanding biobehavioral research.
Inhibition in vitro of acyl-CoA dehydrogenases by 2-mercaptoacetate in rat liver mitochondria (1983)

In rat liver hypo-osmotically treated mitochondria, 2-mercaptoacetate inhibits respiration induced by palmitoyl-CoA, octanoate or butyryl-CoA only when the reaction medium is supplemented with ATP. Under this condition, NADH-stimulated respiration is not affected. In liver mitochondrial matrix, the presence of ATP is also required to observe a 2-mercaptoacetate-induced inhibition of acyl-CoA dehydrogenases tested with palmitoyl-CoA, butyryl-CoA or isovaleryl-CoA as substrate. As the oxidation of these substrates is also inhibited by the incubation medium resulting from the reaction of 2-mercaptoacetate with acetyl-CoA synthase, with conditions under which 2-mercaptoacetate has no effect, 2-mercaptoacetyl-CoA seems to be the likely inhibitory metabolite responsible for the effects of 2-mercaptoacetate. Kinetic experiments show that the main effect of the 2-mercaptoacetate-active metabolite is to decrease the affinities of fatty acyl-CoA dehydrogenases towards palmitoyl-CoA or butyryl-CoA and of isovaleryl-CoA dehydrogenase towards isovaleryl-CoA. Addition of N-ethylmaleimide to mitochondrial matrix pre-exposed to 2-mercaptoacetate results in the immediate reversion of the inhibitions of palmitoyl-CoA and isovaleryl-CoA dehydrogenations and in a delayed reversion of butyryl-CoA dehydrogenation. These results led us to conclude that (i) the ATP-dependent conversion of 2-mercaptoacetate into an inhibitory metabolite takes place in the liver mitochondrial matrix and (ii) the three fatty acyl-CoA dehydrogenases and isovaleryl-CoA dehydrogenase are mainly competitively inhibited by this compound. Finally, the present study also suggests that the inhibitory metabolite of 2-mercaptoacetate may bind non-specifically to, or induce conformational changes at, the acyl-CoA binding sites of these dehydrogenases.
Relevant spectro-temporal modulations for robust speech and nonspeech classification. (2010)

Robust speech/non-speech classification is an important step in a variety of speech processing applications. For example, in speech and speaker recognition systems designed to work in real world environments, a robust discrimination of speech from other sounds is an essential pre-processing step. Auditory-based features at multiple-scales of time and spectral resolution have been shown to be very useful for the speech/non-speech classification task [Mesgarani et al., IEEE Trans. Speech Audio Process. 10, 504–516 (2002)]. The features used are computed using a biologically inspired auditory model that maps a given sound to a high-dimensional representation of its spectro-temporal modulations (mimicking the various stages taking place along the auditory pathway from the periphery all the way to the primary auditory cortex). In this work, we analyze the contribution of different temporal and spectral modulations for robust speech/non-speech classification. The results suggest the temporal modulations in the range 12–22 Hz, and spectral modulations in the range 1.5–4 cycles/octave are particularly useful to achieve the robustness in highly noisy and reverberant environments.
Time-resolved White-light Interferometry for Ultrafast Metrology (2010)

The material modification in the volume of transparent dielectrics using tightly focused fs-laser radiation is an important topic for many research groups all over the world. A wide range of applications like the writing of waveguides, micro-structuring by material modification and subsequent etching, or the micro-welding of glass is based on the localized melting and quenching in a different state. Time-resolved white-light interferometry is adopted for the measurement of the optical phase changes in processed materials. A modified Mach-Zehnder interferometer setup combined with microscope objectives is used. The white light is generated by focusing ultrafast laser radiation (t p=80 fs) in a sapphire crystal using a micro-lens array to minimize temporal and spatial fluctuations in the white-light continuum. Lateral and coaxial pump-probe measurements of the phase changes during material processing are performed using one or two coupled ultrafast laser sources at different repetition rates (frep=1kHz-1MHz) or by adopting single pulses. The temporal delay between the pump and the probe can be adjusted in the range τ ≤1.8 μs in dependence on the repetition rate of the pump radiation. The optical phase shift and therefore the refractive index of the material is calculated from the interference images. The knowledge of the refractive index during the modification process with a temporal resolution in the ps-range and a spatial resolution of several microns leads to a better understanding of the initial processes for the permanent material modifications. © 2010 American Institute of Physics.
Circuit Masking: From Theory to Standardization, A Comprehensive Survey for Hardware Security Researchers and Practitioners (2021)

Side-channel attacks extracting sensitive data from implementations have been considered a major threat to the security of cryptographic schemes. This has elevated the need for improved designs by embodying countermeasures, with masking being the most prominent example. To formally verify the security of a masking scheme, numerous attack models have been developed to capture the physical properties of the information leakage as well as the capabilities of the adversary. With regard to these models, extensive research has been performed to realize masking schemes. These research efforts have led to significant progress in the development of security assessment methodologies and further initiated standardization activities. However, since the majority of this work is theoretical, it is challenging for the more practice-oriented hardware security community to fully grasp and contribute to. To bridge the gap, these advancements are reviewed and discussed in this survey, mainly from the perspective of hardware security. In doing so, a clear taxonomy is provided that is helpful for a systematic treatment of the masking-related topics. By giving an extensive overview of the existing methods, this survey (1) provides a research landscape of circuit masking for newcomers to the field, (2) offers guidelines on which attack model and verification tool to choose when designing masking schemes, and (3) identifies interesting new research directions where masking models and assessment tools can be applied. Thus, this survey serves as an essential reference for hardware security practitioners interested in the theory behind masking techniques, the tools useful to verify the security of masked circuits, and their potential applications.

Alpha-1 Antitrypsin PiMZ Genotype Is Associated with Chronic Obstructive Pulmonary Disease in Two Racial Groups (2017)

In the COPDGene Study, we demonstrate that PiMZ heterozygous individuals who smoke are at increased risk for COPD and obstructive lung function impairment compared with Z-allele noncarriers, regardless of race. Although severe alpha-1 antitrypsin deficiency is uncommon in African Americans, our study adds further support for initial targeted detection of all subjects with COPD for alpha-1 antitrypsin deficiency, including African Americans. Clinical trial registered with www.clinicaltrials.gov (NCT00608784).
Cloud Feature Extraction and Fluctuation Pattern Recognition Based Ultrashort-Term Regional PV Power Forecasting (2022)

Regional photovoltaic(PV) power forecasting provides a foundation for grid management and trading in the power markets. To tackle the deficiency of conventional regional PV power modeling methods, such as the problem of challenging to select useful meteorological information and the problem that a single model cannot fully learn the complex and diverse fluctuation characteristics of power curves, an ultrashort-term regional PV power forecasting framework assembled by fusing fluctuation pattern recognition (FPR) and deep learning modeling under a fluctuation pattern prediction (FPP) model was proposed. First of all, the fluctuation characteristics of the regional PV power curves were extracted, including sampling loss area, mean value, standard deviation, and third derivative. Then, a K-means algorithm based FPR model was established to obtained three kinds of patterns. FPP model based on convolutional neural network is used to predict future PV power fluctuation patterns with historical satellite images as input. Finally, the convolutional autoencoder is used to extract cloud distribution features, and a long- and short-term memory network based on the combination of cloud distribution features and historical output is proposed to construct prediction models of the three models. Through the analysis of the simulation data, the prediction method proposed in this article has higher prediction accuracy than the traditional prediction model.
Lipofuscin pigment in adult Clonorchis sinensis (1983)

Adult Clonorchis sinensis from infected human cases may have black pigment in their parenchyme. In present paper, the nature of the pigment was investigated. The pigment distributed in cytoplasm of parenchymal cells of the worms. Histochemically the pigment was positive by periodic acid-Schiff, Ziehl-Neelsen, and lipofuscin stainings. The pigment particle contained many, various sized membrane structure as well as electron dense granules when observed by electron microscopy. Staining characteristics of the black pigment, together with electron microscopic findings, strongly indicated that the pigment was lipofuscin.
Fully printed tunable phase shifter for L/S-band phased array application (2014)

In this paper, a novel fully printed method is presented for fabrication of phase shifter devices, aiming for phased array applications. This technology offers a simple and low cost way compared to other available technologies. The proposed phase shifter contains tunable ferroelectric varactors in metal-insulator-metal (MIM) configuration, which are fully printed on top of a carrier substrate. The printed phase shifter exhibits a figure of merit (FoM) of 70°/dB at 1.72GHz and shows a high potential for an implementation in fully printed phased array antennas.
Trap-based Positron Beams (2005)

The ability to accumulate large numbers of positrons in Penning traps and to manipulate them using nonneutral plasma techniques offers a completely new approach to creating high quality positron beams. This approach provides significant advantages over conventional positron beam technology with regard to beam brightness, flux, and system cost. The application of these techniques has already resulted in a new generation of bright, ultracold positron beams with state-of-the-art performance. These beams are currently being exploited in the area of atomic physics studies, but they also have the potential for uses in other areas of science and technology, such as materials science. The current status of trap-based positron beams is described and the potential for further development is discussed.
High precision radar echo modelling and simulation method (2008)

Detailed mathematical modelling of the exact radar echo and the software implementation methods are presented in this paper. The analysis of the ldquostop-and-gordquo assumption indicates that the assumption cannot be adopted in some circumstances. The implementation methods of the radar echo simulation are discussed and analyzed in detail, and a methodology to implement the high precision echo simulation is provided. Finally, we give an example of the high resolution synthetic aperture radar (SAR) echo model, and the simulation of the SAR system validates the exact echo model and the implementation methods. Such model and methodology are important in the simulation for a high precision radar system as well as in the algorithm performance evaluation and system performance analysis.
Lost and Found (1986)

Lost and Found Lost by the mire where swamp haw thrives and violet corts thumb up from marsh mulch, I scanned in vain for a sign of sun in the clouds to point west before dusk sentenced me to night in the bog, but light where cypress shadows merged was a blur, and no moss favored one side of an oak to say north. Insects chirred as I circled, thinking the hawk's way best, but I was still bewildered and beginning to sense thirst when I found a field of wild saxifrage which can break rock, dissolve gall stones or work as a starved man's salad. Then a stand of dwarf ginseng, fleshy and best raw, which my kin use to stimulate the heart. On the fringe grew hairy herbs I knew from Granddad's tales bow always north and serve as calming tea, the white flowers dropping pollen on bent leaves saying: this way, comfrey, comfort, come home. —R.T.

Improving iron status before pregnancy predictors for time to first pregnancy in rural Bangladesh (2006)

It has recently been advocated that iron supplementation begin before childbearing. A key&#13;\noperational issue is timely identification of !~males prior to pregnancy. The purpose of this&#13;\nstudy was to examine factors associated with time to first pregnancy ( FP) and adolescent&#13;\npregnancy (AP). /\\ cross-sectional survey was conducted in Gazipur. Bangladesh (April-May&#13;\n2006) among ever married females aged &lt; 50 y. Data on 603 females were analysed. Mean age&#13;\nwas 32 y .t 9. Only 15%, (7/47) of never pregnant females reported iron use in the past 6 mo.&#13;\nMean age at marriage was 17 y 1: 3 at marriage. 58% (322/556) of females were &lt; l8 y at fP.&#13;\nMedian time from marriage to FP was 12 mo (range: 0-408). Multivariate hazard analysis&#13;\nfound risk of pregnancy increased by 13% for every y increase in age at marriage ( p&lt;O.OOO I)&#13;\nand decreased by 3% for every y increase in female's current age (p·~O.OOO I). Risk among&#13;\nmedical contraceptive users was 58% of the risk among non-users (p'-='0.000 I). Using&#13;\nmultivariate logistic regression analysis the probability of an AP decreased by 3% for each y of&#13;\nmarriage during adolescence (CI: 0.95-0.99), by 10% for every y increase in husband's age at&#13;\nmarriage (CI: 0.87-0.94), by 68% among female wage earners compared to non-wage earners&#13;\n(CI: 0.16-0.64) and by SO% among medical contraceptive users compared to non-users (CI:&#13;\n0.30-0.85). In this population females arc married at a young age with short time to FP&#13;\nintervals. Pcriconceptional iron supplementation programs should target adolescents and&#13;\nnewly-weds.
Normalized Diversification (2019)

Generating diverse yet specific data is the goal of the generative adversarial network (GAN), but it suffers from the problem of mode collapse. We introduce the concept of normalized diversity which force the model to preserve the normalized pairwise distance between the sparse samples from a latent parametric distribution and their corresponding high-dimensional outputs. The normalized diversification aims to unfold the manifold of unknown topology and non-uniform distribution, which leads to safe interpolation between valid latent variables. By alternating the maximization over the pairwise distance and updating the total distance (normalizer), we encourage the model to actively explore in the high-dimensional output space. We demonstrate that by combining the normalized diversity loss and the adversarial loss, we generate diverse data without suffering from mode collapsing. Experimental results show that our method achieves consistent improvement on unsupervised image generation, conditional image generation and hand pose estimation over strong baselines.
Wide-band suppression of photon-number fluctuations in a high-speed light-emitting diode driven by a constant-current source (1998)

We demonstrate experimental results on the generation of sub-Poissonian photon fluxes emanating from an AlGaAs light-emitting diode, which manifest a wide-band (0–100 MHz) noise suppression below the standard quantum limit level despite low current density (∼38 A/cm2) operation at room temperature. The experimental noise power spectrum is well fitted in terms of the theoretical curve estimated with the quantum mechanical Langevin equations.
Optimization of a transverse flux machine with claw-pole and flux-concentrating structure (2015)

This paper deals with the multi-objective optimization of a transverse flux machine with claw-pole and flux-concentrating structure (CPTFM), which is especially suitable for low-speed and high-torque applications due to its high pole pair number. Compared with conventional radial flux machine, the main flux path in CPTFM is three dimensional and transverse to the rotation of the rotor. For this reason, the time-consuming 3D finite element method is necessary to accurately investigate the performance of CPTFM. In order to optimize the electrometric design of CPTFM and meanwhile to limit the calculation time to an acceptable level, a method mainly based on the Taguchi method and the Nondominated Sorting Genetic Algorithm 2 is developed in this paper. From the comparison between the final optimized design and the original design, it is concluded that all the specified five objectives are improved and the developed method is feasible and effective, which makes a appropriate compromise between the calculation time and optimization results.
Neurotrophins: Peripherally and centrally acting modulators of tactile stimulus-induced inflammatory pain hypersensitivity (1999)

Brain-derived neurotrophic factor (BDNF) is expressed in nociceptive sensory neurons and transported anterogradely to the dorsal horn of the spinal cord where it is located in dense core vesicles in C-fiber terminals. Peripheral inflammation substantially up-regulates BDNF mRNA and protein in the dorsal root ganglion (DRG) in a nerve growth factor-dependent fashion and results in novel expression of BDNF by DRG neurons with myelinated axons. C-fiber electrical activity also increases BDNF expression in the DRG, and both inflammation and activity increase full-length TrkB receptor levels in the dorsal horn. Sequestration of endogenous BDNF/neurotrophin 4 by intraspinal TrkB-Fc fusion protein administration does not, in noninflamed animals, change basal pain sensitivity nor the mechanical hypersensitivity induced by peripheral capsaicin administration, a measure of C fiber-mediated central sensitization. TrkB-Fc administration also does not modify basal inflammatory pain hypersensitivity, but does block the progressive hypersensitivity elicited by low-intensity tactile stimulation of inflamed tissue. BDNF, by virtue of its nerve growth factor regulation in sensory neurons including novel expression in A fibers, has a role as a central modulator of tactile stimulus-induced inflammatory pain hypersensitivity.

Evaluation of the prototype optical tape recorder as a bit-machine (2002)

In 1996 an improved design for a prototype Optical Tape Recorder was presented. The recorder is now operational and is currently being evaluated. We report on the results of tests of the various servo-systems and of the recording and play-back functions. The tracking and focus servo both have 1 kHz bandwidth which proves to be more than sufficient in our configuration. Recording and play-back experiments are currently run on write-once tape. The data density is currently still half CD-density, to allow for sufficient margins during testing of the equipment, but we have shown in off-line experiments that full CD-density recording on tape is possible.
