A Review of Aerosol Chemical Composition and Sources in Representative Regions of China during Wintertime

Comparisons of aerosol composition and sources in different cities or regions are rather limited, yet important for an in-depth understanding of the spatial diversity of aerosol pollution in China. In this study, the data originating from 25 different winter aerosol mass spectrometer (AMS)/aerosol chemical speciation monitor (ACSM) studies were used to provide spatial coverage of the Beijing-Tianjin-Hebei (BTH), Guanzhong (GZ), Yangtze River Delta (YRD), and Pearl River Delta (PRD) regions. The spatial distribution and diurnal variations in aerosol composition and organic sources were analyzed to investigate the aerosol characteristics in the four regions. It was found that there were differences in the compositions of non-refractory particulate matter across the regions, e.g., more sulfate in the PRD versus more nitrate in the YRD, as well as in the organic sources, e.g., more coal combustion in BTH versus more biomass burning in GZ. The characteristics of the composition of NR-PM are similar when the campaigns were classified according to the winter of different years or the cities of different regions. The diurnal variation of the PRD-sulfate indicated its regional nature, whereas the organics from burning sources in two regions of northern China exhibited local characteristics. Based on these findings, we suggest that strict control policies for coal combustion and biomass burning emissions should be enforced in the BTH and GZ regions, respectively.
The influence of shift work on health behaviors and self-reported health status of nurses

Abstract Introduction. Working conditions often involve employees’ exposure to factors having adverse effects on their health. Due to its nature, the nursing profession entails numerous risks, associated both with harmful factors and a work system itself. Aim. Aim of this study was to analyze the influence of a shift work system on self-reported health status and health behaviors of nurses. Material and methods. The study included 200 nurses employed in three Szczecin hospitals: the Independent Public Clinical Hospital no. 1, Pomeranian Medical University in Szczecin, Independent Public Clinical Hospital no. 2, Pomeranian Medical University in Szczecin, and Independent Public Voivodeship Integrated Hospital. The research instruments were the Health Behavior Inventory (HBI) developed by Zygfryd Juczyński, and a self-developed questionnaire concerning sociodemographic and medical data. Results. When it comes to 76% of the nurses, they described their health status as good or very good. The majority of the respondents (54%) displayed a low level of health behaviors. The most common work-related complaints were sleep disorders (55%), headaches after return home from work (55%), irritation after return home from work (83%), skin problems (28%), back pains (76%), leg pain/fatigue (84%), and eating disorders (14%). Conclusions. 1. A work system had substantial effect on self-reported health status of the studied group of nurses. 2. The nurses working day shifts displayed a higher level of health behaviors than their counterparts working in a shift system. 3. A day/night shift work pattern correlated with a higher incidence of eating disorders.
Chromatin structure-dependent histone incorporation revealed by a genome-wide deposition assay

In eukaryotes, histone variant distribution within the genome is the key epigenetic feature. To understand how each histone variant is targeted to the genome, we developed a new method, in which epitope-tagged histone complexes are introduced into permeabilized cells and incorporated into their chromatin. We found that the incorporation of histones H2A and H2A.Z mainly occurred at less condensed chromatin (open), suggesting that the condensed chromatin (closed) is a barrier for histone incorporation. To overcome this barrier, H2A, but not H2A.Z, uses a replication-coupled deposition mechanism. This led to the recapitulation of the pre-existing chromatin structure: the genome-wide even distribution of H2A and the exclusion of H2A.Z from the closed chromatin. Intriguingly, an H2A.Z mutant with mutations in the developmentally essential region was incorporated into closed chromatin. Our study revealed that the combination of chromatin structure and DNA replication dictates the differential histone deposition for maintaining the epigenetic chromatin states.
Public Policy Supporting Regional Economic Development through Analysis and Education about the Authors about the Center for Applied Economics Public Policy and Entrepreneurship

Entrepreneurship is a primary catalyst for economic growth and regional development. Recognizing its importance, state and local policymakers are now devoting considerable resources to fostering entrepreneurship. After a brief discussion of the data and theories of entrepreneurship, this paper presents a framework for thinking about government’s role in the entrepreneurial process. We then examine the research on macro-level determinants of entrepreneurial activity and find that policies broadly consistent with economic freedom, such as secure property rights, low taxes, and low regulations lead to a robust entrepreneurial environment.
Identifying gene function and module connections by the integration of multispecies expression compendia

The functions of many eukaryotic genes are still poorly understood. We developed and validated a new method, termed GeneBridge, which is based on two linked approaches to impute gene function and bridge genes with biological processes. First, Gene-Module Association Determination (G-MAD) allows the annotation of gene function. Second, Module-Module Association Determination (M-MAD) allows predicting connectivity among modules. We applied the GeneBridge tools to large-scale multi-species expression compendia—1,700 datasets with over 300,000 samples from human, mouse, rat, fly, worm, and yeast—collected in this study. Unlike most existing bioinformatics tools, GeneBridge exploits both positive and negative gene/module-module associations. We constructed association networks, such as those bridging mitochondria and proteasome, mitochondria and histone demethylation, as well as ribosomes and lipid biosynthesis. The GeneBridge tools together with the expression compendia are available at systems-genetics.org, to facilitate the identification of connections linking genes, modules, phenotypes, and diseases.
Effect of the antifreeze protein on the microstructure of strawberries (Fragaria ananassa Duch)

Abstract The present work aimed to evaluate the effect of the antifreeze protein on the microstructure and physicochemical properties of hidroponic strawberries, evaluating the titratable acidity, pH, colour and optical microscopy before freezing both in natura (IN) and impregnated with the protein (IP), and after thawing without the protein (TWP) and impregnated (TIP) with the antifreeze protein (AFP Type I from fish) by vacuum impregnation. After thawing, the treatment was also compared in terms of drip losses. The antifreeze protein impregnated strawberries showed no statistical differences with respect to the physicochemical properties, but the drip loss was statistically lower from the thawed strawberries treated with the antifreeze protein. The vacuum impregnated thawed strawberries showed less damage to the microstructure. The cells of the thawed samples with antifreeze protein conserved the structure of the reference samples of in natura strawberry.
Kelussia odoratissima Mozaffarian inhibits ileum contractions through voltage dependent and beta adrenergic receptors

The anti-spasm properties of Kelussia odoratissima Mozaffarian have been mentioned in Iranian traditional medicine and it is used to gastrointestinal disorders treatment. The plant leaf alcoholic extract cumulative effect of this plant on Wistar rats ileum contractions and expression of its probable mechanism was investigated in this research. Hydro-alcoholic extract was prepared by maceration method using 70% ethanol. Forty eight male Wistar rats (150-200 g) were randomly designated to 6 random groups with 8 rats in each, in this interventional research as following. Control group, cumulative concentrations of Kelussia odoratissima Mozaffarian extract receiving group, propranolol receiving group, naloxone receiving group, L-NAME receiving group, and sodium chloride receiving group. Ileum samples were taken from rat and subjected to lgr tension in tissue-bath containing tyrode solution. Isotonic contractions was recorded following addition of potassium chloride (60mM), saline or 10% and 20% cumulative concentrations of Kelussia odoratissima Mozaffarian extract. In order to understand the above mechanism, ileum was incubated with L-NAME, naloxone or propranolol and also affected by different doses of calcium chloride. Then, the observed effect was recorded and the variation percentage was calculated. Statistical analysis was performed by parametric test, repeated measures, ANOVA and t test. Findings: 10% and 20% cumulative concentrations from alcoholic extracts of Kelussia odoratissima Mozaffarian could reduce contractions caused by potassium chloride (P 0.05). Beta adrenergic receptor blocker (1 mu M propranolol), significantly decreased the contractions caused by potassium chloride (P-value=0.013) but nitric oxide inhibitor (100 mu M L-NAME) and opioid receptor blocker (1 mu M naloxone) had no effect on this contraction. Calcium was also caused tissue contraction depolarized by potassium chloride and this contraction effect reduced by cumulative concentration (P<0.001). In general it can be concluded that Kelussia alcoholic extracts can inhibit ileum contractions of rat through the effect on voltage dependent and beta adrenergic receptors and it might be used to relieve intestinal spasms.

Exploring Option Pricing and Hedging via Volatility Asymmetry

This paper evaluates the application of two well-known asymmetric stochastic volatility (ASV) models to option price forecasting and dynamic delta hedging. They are specified in discrete time in contrast to the classical stochastic volatility models used in option pricing. There is some related literature, but little is known about the empirical implications of volatility asymmetry on option pricing. The objectives of this paper are to estimate ASV option pricing models using a Bayesian approach unknown in this type of literature, and to investigate the effect of volatility asymmetry on option pricing for different size equity sectors and periods of volatility. Using the S&P MidCap 400 and S&P 500 European call option quotes, results show that volatility asymmetry benefits the accuracy of option price forecasting and hedging cost effectiveness in the large-cap equity sector. However, ASV models do not improve the option price forecasting and dynamic hedging in the mid-cap equity sector.
Managing Innovation Networks: A Multiplex Analysis of the Global Wind Power Industry

In this article, we treat innovation as a multidimensional construct spanning people, technologies, and geographies. We study how these dimensions interact and impact firms' inventor networks and the ultimate innovation performance. We identify five distinct planes in which inventor networks reside. Specifically, we distinguish between the types of ties that are possible between any two inventor nodes with respect to (i) co-located inventors; (ii) technology cohort; (iii) co-located technology cohort; (iv) distant co-inventors; and (v) co-located coinventors. We build a simple, yet parsimonious model of the costs and benefits of being centrally located on multiplex network versus having an equal distribution of ties between the different network layers. Using patent data on the global wind power industry, we find evidence suggesting that being centrally positioned on a multiplex network with an equal distribution of ties deteriorates rather than enhances innovation performance.
Compact and Circularly Polarized Hemispherical DRA for C-Band Applications

Abstract A novel circular polarized Hemispherical Dielectric Resonator Antenna (HDRA) has been proposed in this paper. The Circular Polarization (CP) and enhanced gain characteristics of the antenna are attributed to the fractal geometry applied on the HDRA. Probe coupling is used to excite the proposed antenna which resonates at 4.16 GHz and offers an impedance bandwidth of 2.6 GHz (57 %), from 3.3 to 5.9 GHz. The gain and efficiency of the antenna are 6.38 dBi and 93 % respectively at 4.16 GHz. The Proposed DRA is designed using FR-4 material having a dielectric constant (εr ) of 4.3 and dissipation factor (tan δ) of 0.025. The designed Antenna is experimentally verified and offers a close agreement between simulated and measured results. This Antenna offers a 3-dB Axial Ratio (AR) bandwidth of 1.1 GHz from 4.2 to 5.3 GHz.
Mutual Coupling-Based Compact Wideband Circularly Polarized Antenna

A small-size wideband circularly polarized (CP) antenna is introduced. The key innovation is that the antenna is based on four confined highly coupled microstrip patches fed by a composed right-left-hand integrated feeding network (FN). Mutual coupling is thus effectively used in a constructive way. It is shown that this idea results in an excellent combination of axial ratio (AR) bandwidth and small size. A prototype was built and measured proving the concept in practice. The impedance bandwidth is 110%, the AR bandwidth at broadside is more than 83%, and the −3 dB gain bandwidth (with respect to maximum gain) is 65%, with an overlap of 63% when considering all the three at the same time. The antenna lateral size is as small as <inline-formula> <tex-math notation="LaTeX">$0.52\lambda 0\times 0.52\lambda 0$ </tex-math></inline-formula>, where <inline-formula> <tex-math notation="LaTeX">$\lambda 0$ </tex-math></inline-formula> is the midband wavelength.

Triple categorical regression for genomic selection: application to cassava breeding

Genome-wide selection (GWS) is currently a technique of great importance in plant breeding, since it improves efficiency of genetic evaluations by increasing genetic gains. The process is based on genomic estimated breeding values (GEBVs) obtained through phenotypic and dense marker genomic information. In this context, GEBVs of N individuals are calculated through appropriate models, which estimate the effect of each marker on phenotypes, allowing the early identification of genetically superior individuals. However, GWS leads to statistical challenges, due to high dimensionality and multicollinearity problems. These challenges require the use of statistical methods to approach the regularization of the estimation process. Therefore, we aimed to propose a method denominated as triple categorical regression (TCR) and compare it with the genomic best linear unbiased predictor (G-BLUP) and Bayesian least absolute shrinkage and selection operator (BLASSO) methods that have been widely applied to GWS. The methods were evaluated in simulated populations considering four different scenarios. Additionally, a modification of the G-BLUP method was proposed based on the TCR-estimated (TCR/G-BLUP) results. All methods were applied to real data of cassava (Manihot esculenta) with to increase efficiency of a current breeding program. The methods were compared through independent validation and efficiency measures, such as prediction accuracy, bias, and recovered genomic heritability. The TCR method was suitable to estimate variance components and heritability, and the TCR/G-BLUP method provided efficient GEBV predictions. Thus, the proposed methods provide new insights for GWS.

A Wide-Angle Narrowband Leaky-Wave Antenna Based on Substrate Integrated Waveguide-Spoof Surface Plasmon Polariton Structure

In this letter, a wide-angle narrowband leaky-wave antenna (LWA) based on substrate integrated waveguide-spoof surface plasmon polariton (SIW-SSPP) structure is proposed. Periodic slots are etched on both the top and bottom surfaces of SIW to introduce an SSPP mode. The periodic slots on the top surface are sinusoidally modulated to realize bidirectional LWA radiation. The problem of open stopband is solved by the asymmetrical design of the top and bottom slots. Thus, a wide bidirectional scanning range from −60° to +63° is achieved. Besides, the relative bandwidth of the fabricated antenna is reduced to only 9% by introducing the slow-wave effect of SSPP. It means the proposed antenna has a large scanning rate, or equivalently beam scanning range/bandwidth ratio.
What is the theory ZFC without power set?

We show that the theory ZFC- , consisting of the usual axioms of ZFC but with the power set axiom removed—specifically axiomatized by extensionality, foundation, pairing, union, infinity, separation, replacement and the assertion that every set can be well‐ordered—is weaker than commonly supposed and is inadequate to establish several basic facts often desired in its context. For example, there are models of ZFC- in which ω1 is singular, in which every set of reals is countable, yet ω1 exists, in which there are sets of reals of every size ℵn , but none of size ℵω , and therefore, in which the collection axiom fails; there are models of ZFC- for which the Łoś theorem fails, even when the ultrapower is well‐founded and the measure exists inside the model; there are models of ZFC- for which the Gaifman theorem fails, in that there is an embedding j:M→N of ZFC- models that is Σ1‐elementary and cofinal, but not elementary; there are elementary embeddings j:M→N of ZFC- models whose cofinal restriction j:M→⋃j""M is not elementary. Moreover, the collection of formulas that are provably equivalent in ZFC- to a Σ1‐formula or a Π1‐formula is not closed under bounded quantification. Nevertheless, these deficits of ZFC- are completely repaired by strengthening it to the theory ZFC− , obtained by using collection rather than replacement in the axiomatization above. These results extend prior work of Zarach .
Energy Provision Minimization in Wireless Powered Communication Networks With Node Throughput Requirement

Radio-frequency (RF) energy harvesting is one of the promising technologies in wireless networks. This paper considers wireless powered communication networks (WPCNs) where one hybrid access point (H-AP) coordinates RF energy/information transmissions to/from a set of nodes. For the important type of WPCNs where the nodes have throughput requirement, we aim to minimize H-AP's energy provision (EP) via jointly optimizing the time allocation of energy/information transmissions and H-AP's transmission power while satisfying node throughput requirement. More specifically, the half-duplex WPCN is considered first. We prove that H-AP's energy transmission power must be the maximum allowed value to achieve the minimal EP, then show that the problem is convex under this condition and finally design an algorithm applying golden section search and bisection search jointly to efficiently obtain the optimal time allocation. Second, the full-duplex WPCN is considered. Its EP minimization problem is proved convex. However, due to the hardness of solving it directly, we turn to solve the feasibility problem (FP) for a given EP per unit time. We construct a convex optimization problem based on this FP and design a dual subgradient algorithm for finding its optimal solution, which indicates whether this FP is feasible. The minimal EP per unit time and its corresponding optimal solution are found by using the bisection search method. Simulation results show that, the EP-minimized schemes are able to greatly reduce H-AP's EP as compared to the baseline schemes.
