A QoE-Aware Resource Allocation Algorithm for D2D Communication Underlaying Cellular Networks

This paper proposes a QoE-aware resource allocation (EARA) algorithm for D2D communication underlaying a cellular network. The proposed EARA algorithm takes into account the service completion time in spectrum resource allocation, and aims to complete the data service of a D2D user within its expected service completion time and meanwhile ensure a satisfying QoE of a D2D pair during the entire process of the data service. To this end, time is divided into a sequence of timeslots of fixed length and a parameter called k-QoE is introduced to measure the QoE of a D2D pair in the kth timeslot. The value of k-QoE is used to determine the priority of a D2D pair in resource allocation and a D2D pair with a smaller value of k-QoE is given a higher priority to obtain spectrum resources in order to ensure the QoE of the D2D user. Simulation results show the proposed EARA algorithm can achieve a better performance in terms of the average service completion satisfaction ratio, the average QoE of D2D pairs, and the overall throughput of the system as compared with a max-throughput resource allocation algorithm for D2D communication.
Texture Transfer Based on Energy Minimization for Painterly Rendering

Non-photorealistic rendering (NPR) creates images with artistic styles of paintings. In this field, a number of methods of converting photographed images into non-photorealistic ones have been developed, and can be categorized into filter-based and exemplar-based approaches. In this paper, we focus on the exemplar-based approach and propose a novel method which transfers a style of a reference pictorial image to a photographed image. Specifically, we first input a pair of target and reference images. The target image is converted by minimizing an energy function which is defined based on the difference in intensities between an output image and a target image, and the pattern dissimilarity between an output image and a reference image. The proposed method transfers structures and colors of textures in the reference image and generates continuous textures by minimizing the energy function. In experiments, we demonstrate the effectiveness of the proposed method using a variety of images and examine the influence of parameter changes and intensity adjustment for pre-processing on resultant images.
Finding Zeros of Analytic Functions: alpha Theory for Secant Type Methods

Abstract We present new results concerning the convergence of secant type methods with only conditions at a point. The radius of robustness of these methods is given, and we apply it to the study of the complexity of homotopy methods for approximating roots. In particular, we say how to use the secant type method to get an approximate zero relative to the Newton method.
Consensus Problem in Wireless Ad hoc Networks: Addressing the Right Issues

Solving consensus in wireless ad hoc networks has started to be addressed in several papers. Most of these papers adopt system models developed for wired networks. These models are focused towards node failures while ignoring link failures, and thus are poorly suited for wireless ad hoc networks. The HO model, which was proposed recently, does not have this drawback. The paper shows that an existing algorithm and the HO model can be used for multi-hop wireless ad hoc networks, if extended with an adequate "implementation". The meaning of "implementation" will become clear from the paper. The description of the "implementation" is augmented with simulation results that validate the feasibility of our approach and provide better understanding of the behavior of realistic wireless environments.
A smart exponential‐threshold‐linear backoff mechanism for IEEE 802.11 WLANs

Based on the standardized IEEE 802.11 Distributed Coordination Function (DCF) protocol, this paper proposes a new backoff mechanism, called Smart Exponential‐Threshold‐Linear (SETL) Backoff Mechanism, to enhance the system performance of contention‐based wireless networks. In the IEEE 802.11 DCF scheme, the smaller contention window (CW) will increase the collision probability, but the larger CW will delay the transmission. Hence, in the proposed SETL scheme, a threshold is set to determine the behavior of CW after each transmission. When the CW is smaller than the threshold, the CW of a competing station is exponentially adjusted to lower collision probability. Conversely, if the CW is larger than the threshold, the CW size is tuned linearly to prevent large transmission delay. Through extensive simulations, the results show that the proposed SETL scheme provides a better system throughput and lower collision rate in both light and heavy network loads than the related backoff algorithm schemes, including Binary Exponential Backoff (BEB), Exponential Increase Exponential Decrease (EIED) and Linear Increase Linear Decrease (LILD).

Dynamic Performance Estimation of High-Power FESS Using the Operating Torque of a PM Synchronous Motor/Generator

In our high-power flywheel energy storage system, the heavy and large flywheel is rotated by the electromagnetic torque of a permanent-magnet (PM) synchronous motor (PMSM) and, in case of a breakdown of electric current, this motor used as a generator supplies electric energy to the various electric utilities using mechanical rotation energy of the flywheel. Thus, the dynamic performance of the flywheel is related to the electromagnetic torque for the motoring and generating power of the PMSM/G. Moreover, in the idling mode without generating loads, speed reduction of the flywheel is mainly caused by drag torque generated in the slotless iron-cored stator of this PM machine. In this paper, the operating torque, defined as the electromagnetic torque and drag toque, is estimated from the magnetic-field analysis by the PM rotor with diametrical magnetization. Also, the dynamic performance of the flywheel, according to the driving mode, is simulated from dynamic modeling of the PMSM/G with the operating torque and verified by the experiment.
Dissociative multiphoton ionization of isolated uracil and uracil-adenine complexes Journal Item

Recent multi-photon ionization (MPI) experiments on uracil revealed a fragment ion at m/z 84 that was proposed as a potential marker for ring opening in the electronically excited neutral molecule. The present MPI measurements on deuterated uracil identify the fragment as C3H4N2O (uracil less CO), a plausible dissociative ionization product from the theoretically predicted open-ring isomer. Equivalent measurements on thymine do not reveal an analogous CO loss channel, suggesting greater stability of the excited DNA base. MPI and electron impact ionization experiments have been carried out on uracil-adenine clusters in order to better understand the radiation response of uracil within RNA. Evidence for C3H4N2O production from multi-photon-ionized uracil-adenine clusters is tentatively attributed to a significant population of π-stacked configurations in the neutral beam.
A novel approach to real-time motion detection

A real-time scheme is introduced that meets a need for fast, reliable, multiple-target motion detection without accurate object velocity or structure measurements. A multiresolution approach decomposes images into a pyramid with several spatial frequency bands to selectively detect motion of interest. Multiple moving targets are detected using a multiple window, coarse-to-fine focus of attention scheme to reconstruct motion energy and search for targets. Real-time sensor motion (translation and rotation) compensations use hierarchical correlation and minimum perturbation. Results are shown for multiple moving targets in FLIR (forward-looking infrared) image sequences from both stationary and moving sensors. <<ETX>>
A computational framework for simulation of the delivery of substances into cells

In this paper, we propose a simple computational framework for the rapid simulation of the delivery of substances into cells. Our approach treats the substances and the cell membrane as a collection of particles forming a discrete dynamical system, which is described by Newtonian equations in a purely mechanistic way. Detailed aspects about the modeling of particle interactions are discussed and resolved. The main advantage of such an approach is that it can offer a good qualitative picture of the delivery mechanism without the need to resort to detailed descriptions of the complex intermolecular interactions that are observed at small scales of the cell membrane. A numerical time integration scheme is formulated for solution of the system dynamics, and examples of simulations are provided. Computational particle‐based models render reliable and fast simulation tools. We believe they can be very useful to help advance the design of delivery systems.

Sex differences in histone modifications in the neonatal mouse brain

Sex differences in neural development are established via a number of cellular processes (i.e. migration, death, and survival). One critical factor identified is the neonatal rise in testosterone (T) which activates gene transcription via androgen (AR) and, after aromatization to estradiol, estrogen receptors (ERα and β). Recent evidence shows that AR and ERs interact with histone modifying enzymes. Post-translational modifications of histones, including acetylation and methylation, are involved in transcriptional regulation during normal development. Therefore, we hypothesized that acetylation and/or methylation of histone H3 may underlie sexual differentiation, at least in some regions of the brain. We measured levels of acetylated (H3K9/14Ac) and trimethylated (H3K9Me3) H3 in whole neonatal mouse brains and in three regions: preoptic area+hypothalamus, amygdala, and cortex+hippocampus (CTX/HIP). Sex differences in H3K9/14Ac and H3K9Me3 (males>females) were noted in the CTX/HIP on embryonic day 18, the day of birth, and six days later. To determine if T mediates these changes in H3 modifications, pregnant dams received vehicle or T for the final 4 days of gestation; pup brains were collected at birth. Methylation of H3 was sexually dimorphic despite hormone treatment. In contrast, H3 acetylation in the CTX/HIP of females from T-treated dams rose to levels equivalent to males. Thus, H3 modifications are sexually dimorphic in the developing mouse CTX/HIP and acetylation, but not methylation, is masculinzed in females by T in utero. This is the first demonstration that histone modification is associated with neural sexual differentiation.
Modeling of juice production line using simulation

With more competition and ever changing consumer demands, manufacturers are frequently realizing to reengineer their facility to satisfy the needs of many product groups. In such cases simulation can be a useful tool when analyzing complex production systems to help sort through cause-and effect relationships and gain a better understanding of what is actually causing a particular problem in the system. Once problems are identified, changes for improvement can be made more intelligently and then verified using simulation. The paper presents modeling of juice production line using simulation as tool. Objective is to estimate the present production line utilization and the bottleneck. The subsequent objective is then to suggest and verify a solution to enhance production capacity and reduce the bottleneck which results in the fulfillment of current and future market long term demand. Arena simulation package is used to develop the model.
Subarachnoid Hemorrhage as a Complication of Systemic Lupus Erythematosus

Background: Subarachnoid hemorrhage (SAH) is a rare complication of systemic lupus erythematosus (SLE). Methods: We made a retrospective search for patients with SLE and nontraumatic SAH from 1990 to 2006. Results: We found 10 patients with SLE and primary SAH of a total of 1,077 patients with SLE (0.93%); mean age of onset was 37.4 ± 15.25 years and the mean duration of SLE at the onset of SAH was 98.3 ± 50.32 months. SLEDAI and chronic damage scores were 3.67 ± 5.20 (n = 9) and 2.90 ± 1.45 (n = 10), respectively; 60% of patients had high Hunt-Hess scores and in only 50% of cases a saccular aneurysm was identified. Conclusions: SAH presents in about 1% of SLE patients. Long duration of SLE and chronic damage scores might be associated risk factors.

Modification of response speed deficits and intellectual performance in the elderly.

The present study represents an attempt to explain intellectual decline in old age in terms of experiential and environmental deficit notions. It was hypothesized that test-related response speed in the elderly (n = 32 females; mean age = 70) was modifiable through either practice or reinforced practice. The two-session training program not only increased response speed on the training materials, but also produced slight positive transfer to performance on 11 ability tests. It was suggested thata major proportion of intellectual decline in old age reflects performance rather than competence deficits, and that further research investigating the range of modifiableness of performance indices is necessary for specifying the determinants of intellectual ontogeny during old age.
Design of automatic forest fire positioning system based on video monitoring system

Forest fire prevention is always the focus of attention worldwide, and an important aspect on which governments invest heavily in ecological protection. All of the geographic information (such as latitude and longitude, elevation) has become the public data at the areas deployed forest fire prevention system based on the video monitoring system. It is more expediently to set up the automatic fire point positioning software platform using components of GIS tools. And according to the azimuth angle and the pitching angle returned by the digital PTZ and related methods, the location information of fire point would be obtained. In this paper, the combination of the fire monitoring information and geospatial information achieved the purpose of precise positioning for forest fire point . The system was based on the existing hardware for digital video monitoring system and the basic GIS data of experimental forest farm at Miaofengshan mountain in Beijing, applying ArcGIS geographic information platform and large powerful database technology, referencing exhaustive search algorithm for single point positioning. Overall positioning accuracy is within 100 meters.
Gapping Constructions in Universal Dependencies v2

In this paper, we provide a detailed account of sentences with gapping such as “ John likes tea, and Mary coffee ” within the Universal Dependencies (UD) framework. We explain how common gapping constructions as well as rare complex constructions can be analyzed on the basis of examples in Dutch, English, Farsi, German, Hindi, Japanese, and Turkish. We further argue why the adopted analysis of these constructions in UD version 2 is better suited for annotating treebanks and parsing than previous proposals
Sequential Therapy with Caspofungin and Fluconazole for Candida albicans Infection

ABSTRACT A sequential therapy of caspofungin (CAS) and fluconazole (FLC) administration for treatment of Candida albicans infection was investigated. Treatment with CAS followed by FLC was as effective as CAS treatment given alone for the same duration. Our data suggest that switching from CAS to FLC is a potentially explorable therapeutic option for treatment of systemic candidiasis.
Dynamic Decode and Forward with Network Coding

This paper is divided into two parts. In the first part, we analyze outage probability of dynamic decode and forward (DDF) with network coding (NC) and compare outage probability with using NC and without using NC. In the second part, we use MATLAB programming language to simulate our system model. We simulate outage probability and compare the simulation result with numerical value of outage probability in the first part to prove the correctness of the analytical outage probability. Our results show that network coding can improve the outage probability of considered system model.

GMM ESTIMATION AND INFERENCE IN DYNAMIC PANEL DATA MODELS WITH PERSISTENT DATA

In this paper we consider generalized method of moments–based (GMM-based) estimation and inference for the panel AR(1) model when the data are persistent and the time dimension of the panel is fixed. We find that the nature of the weak instruments problem of the Arellano–Bond (Arellano and Bond, 1991, Review of Economic Studies 58, 277–297) estimator depends on the distributional properties of the initial observations. Subsequently, we derive local asymptotic approximations to the finite-sample distributions of the Arellano–Bond estimator and the System estimator, respectively, under a variety of distributional assumptions about the initial observations and discuss the implications of the results we obtain for doing inference. We also propose two Lagrange multiplier–type (LM-type) panel unit root tests.
Signal Regeneration Adaptive Equalizer for Fast Fading Environment

The signal regeneration method (SRE) and associated adaptive algorithms are proposed for fast fading channels. The adaptive algorithms such as the leaky least mean square (LLMS) algorithm assisted by the SRE method provide the signal-to-interference-noise-ratio (SINR) performance comparable to the linear minimum mean square error (LMMSE) equalizer, with low numerical complexity and low memory requirements. The proposed SRE-LLMS algorithm is analyzed based on the independence assumption, and shown to provide low excessive mean square error (EMSE) compared to the LMS algorithm without incurring a bias in its estimate. The simulation results for the wireless channel models such as VA30 and VA120 are presented to validate the analysis.
Ammonia, Methane, and Carbon Dioxide Concentrations and Emissions of a Hoop Grower-Finisher Swine Barn

Hoop structures have been used quite widely for animal production in the U.S. due to their lower capital costs and multi-purpose versatility. Hoop barns for grower-finisher (G-F) swine production have attracted attention in China as an alternative, environmentally friendly, and water-saving production system. This study was conducted to assess concentrations and emissions of ammonia (NH3) and greenhouse gases (GHGs) for a hoop G-F pig barn at a commercial pig operation in suburban Beijing, China. The NH3 and GHG concentrations and emissions of the facility were measured for three consecutive days during spring and summer seasons. The results revealed the following hourly gaseous concentrations (mean ±SD, mg m-3): 5.9 ±2.7 NH3, 2,183 ±1,376 CO2, and 4.0 ±2.5 CH4 in spring, and 6.8 ±3.4 NH3, 1,530 ±364 CO2, and 5.0 ±2.3 CH4 in summer. The estimated gaseous emissions averaged, in g pig-1 d-1, 22.7 NH3, 2,003 CO2, and 6.7 CH4, or in g AU-1 d-1 (AU = 500 kg), 124 NH3, 11,264 CO2, and 36.2 CH4. The emission values from this study, while being generally comparable with those reported in the literature, add new information concerning emissions from alternative swine housing system.
Vibrio spp. secrete proaerolysin as a folded dimer without the need for disulphide bond formation

Proaerolysin is an extracellular dimeric protein that is secreted across the inner and outer membranes of Aeromonas spp. in separate steps. To investigate the role of protein folding in the second step, one or more cysteine residues were introduced and the mutant proaerolysins were expressed in Aeromonas hydrophila and Aeromonas salmonicida, as well as Vibrio cholerae. Replacing Met‐41 with Cys resulted in expression of a protein that could form a dimer in which the monomers were linked together by a disulphide bridge. A double mutant was also made, in which Gly‐202 and Ile‐445 were replaced with cysteine in order to allow the formation of an intrachain disulphide bridge when the molecule was correctly folded. The M41C covalent dimer and G202C/I445C proaerolysin with the new intrachain bridge were both easily detected inside the bacteria, and they later appeared in the culture supernatants. Small amounts of incorrectly folded proaerolysin were also observed in the cells, but they were not secreted. We conclude that proaerolysin folds and dimerizes before being released from the cell, and that correct folding is a requirement for secretion to occur. The proton ionophore CCCP reduced release of the folded proteins. Unoxidized protein was secreted by cells grown in β‐mercaptoethanol and by a dsbA mutant of V. cholerae, indicating that disulphide bond formation may not be essential for release.
Negative optical phenomena

Negative refractive index meta-materials are new kinds of artificial materials having both negative permittivity and negative permeability. Some negative optical phenomena can be anticipated with negative index, such as inverse Doppler effect, anomalous Cerenkov radiation, and negative refraction. The peculiar properties of meta-materials have been experimentally confirmed, and have aroused strong concern these years. However, negative optical phenomena do not always occur in negative refractive index media. Here we review various negative optical phenomena of meta-materials and other materials. Our recent progress is also given.
