Not Only Health: Environmental Pollution Disasters and Political Trust

Over the past 30 years, the economy of China has sustained rapid growth. However, the extensive development pattern severely deteriorates the ecological environment, which has been recognized as adverse effects on citizens’ physical and mental health. Simultaneously, the political trust in China has been in decline after staying at a high level for a long time. In this paper, we state that, in addition to health issues, environmental pollution can also lead to important political consequences. Using statistics on the occurrence of environmental pollution disasters and a nationally representative survey database in China, we find that environmental pollution disasters can negatively affect citizens’ trust of the government. This relationship persists after a series of endogenous tests and robustness checks. Path analysis indicates that this relationship can be partially mediated by the increase in citizens’ environmental awareness. The cross-sectional analyses on individual characteristics demonstrate that the negative effect of environmental pollution disasters on political trust is less pronounced for female citizens and citizens who are communist party members. Finally, we report that the government’s positive attitudes and activities in resolving environmental pollution problems can partially offset the negative effect of environmental pollution disasters on political trust.
AMPA‐Selective glutamate receptor subunits in astroglial cultures

We analysed AMPA ionotropic receptor subunits at the mRNA level (GluR‐1 to ‐4) and at the protein level (GluR‐1 and GluR‐2/3/4C) in “primary astroglial cultures” (non‐neuronal cell cultures highly enriched in glial fibrillary acidic protein [GFAP] positive cells) prepared from newborn rat cerebral hemispheres, cerebral cortex, hippocamps, and striatum and in “brain non‐neuronal cell cultures” (low percentage of GFAP positive cells) prepared from cerebellum, brainstem, mesencephalon, and hypothalamus. For comparison, we also determined ampa subunit mRNA and protein levels in different brain regions. By Northern blot analysis mRNAs for the AMPA receptor subunits (glur‐1,‐2,‐3,‐4) were detected in primary rat cerebral hemispheres astroglial cultures. Immunoblotting analysis with anti‐GluR‐1 and anti GluR‐2/3/4C polyclonal antibodies confirmed the presence of low leve of immunoreactive proteins of the same size of those identifice in vivo as GluR subunits. Expression of GluR genes varied depending on the brain area used as starting material for the preparation of the cultures: GluR‐1, ‐2, and ‐3 were mailly expressed in cortical cultures, while GluR‐4 expression predominated in brainstem derived cultures. Interestingly this pattern of expression correlates with that observed in the intact brain, where high levels of GluR‐4 mRNA and low levels of the other GluR subunits were found in the brainstem. In conclusion our results confirm the existence of glutmate ionotropic receptors of the AMPA type in primary astroglial cultrues and suggest that GluR‐4 is the main AMPA receptor subunit expressed in non neuronal cells of the central nervous system. © 1993 Wiley‐Liss, Inc.
A Fair Individual Rate Comparison between MIMO-NOMA and MIMO-OMA

In this paper, the individual rates achieved by multiple-input, multiple-output (MIMO) non-orthogonal multiple access (NOMA) and MIMO orthogonal multiple access (OMA) are compared when users are paired into clusters. A power allocation (PA) strategy is proposed, which ensures that MIMO-NOMA achieves a higher individual rate for each user than MIMO-OMA with arbitrary PA and an optimal degrees-of-freedom split. In addition, a special case with equal degrees-of- freedom and arbitrary PA for OMA is considered, for which the individual rate superiority of NOMA still holds. Moreover, it is shown that NOMA can attain better fairness through appropriate PA. Finally, simulations are carried out to validate the developed analytical results.
Design of a Walking Assistance Lower Limb Exoskeleton for Paraplegic Patients and Hardware Validation Using CoP

The design of an assistive lower limb exoskeleton robot for paraplegic patients that can measure the centre of pressure is presented. In contrast with most biped walking robots, the centre of pressure (CoP) or zero moment point (ZMP) has not been actively used in the operation of exoskeleton robots. In order to measure CoP in our exoskeleton robot, two kinds of force sensor units are installed in the exoskeleton: low profile force sensors in foot modules to measure the human weight transferred to the ground and a load cell at the shank frame to measure the supporting force. The CoP of the exoskeleton robot is calculated from the above force sensors, an inclinometer at the waist, and the positions of 14 DOF exoskeleton joints with an algorithm to change the fixed pivot using a foot contact sensor. Experiments on an able-bodied person wearing the designed exoskeleton and walking on the ground are performed to validate the designed hardware system. Through the experiments, the trajectory of the CoP of the exoskeleton with a wearer are calculated based on the proposed algorithm and it is compared with the value measured by a commercial pressure measurement system.
Towards an efficient compression algorithm for seismic data

Seismic data collection involves vast amounts of data in the range of multiple hundreds of terabytes. Very high data compression algorithms are thus required to make seismic data analysis more efficient in terms of storage and transmission bandwidth. We present an adaptive filtering algorithm for seismic data compression based on the wavelet packet transform. The main objective is to achieve higher compression rates for seismic data at a quality above 40 dB in the SNR perspective. The wavelet transform is known for its good localization in time and frequency, a feature that has been utilized for data compression. Wavelet packets are introduced to give extra freedom in selecting appropriate position, scale. and frequency decomposition for more data compression. Our algorithm is developed so that the selection of the best tree decomposition of any given signal is adaptively obtained with respect to an entropy-based criterion. Our algorithm is tested on different seismic data sets. Results indicate that the proposed algorithm is more efficient when compared to other algorithms in the same category without showing any visible artifacts in the decompressed signals.
Quantification of endothelial permeability, leakage space, and blood volume in brain tumors using combined T1 and T2* contrast‐enhanced dynamic MR imaging

This study describes a method for imaging brain tumors that combines T1‐weighted (T1W) and T2*‐weighted (T2*W) dynamic contrast‐enhanced acquisitions. Several technical improvements have been made to produce high‐quality three‐dimensional mapping of endothelial permeability surface area product (k) and leakage space (vl), based on T1W data. Tumor blood volume maps are obtained from T2*W images with a complete removal of residual relaxivity effects. The method was employed in 15 patients with brain tumors (5 gliomas, 5 meningioma, and 5 acoustic schwannoma). Mean values of vl were significantly greater in acoustic schwannomas (53% ± 9%) than in meningiomas (34% ± 7%) or gliomas (22% ± 4%). Mean values of vl in meningioma were significantly greater than those of gliomas. Mean values of rCBV correlated closely with k. There was also a positive correlation between k and vl for pixels with low k values. This relationship was weaker in areas of high k. The highest mean ratios of k to vl (kep) were seen in two patients with glioblastoma, one patient with transitional cell meningioma, and one patient with angioblastic meningioma. Pixel‐by‐pixel comparison showed a strong correlation between rCBV and k in 11 of 15 patients. However, decoupling between pixel‐wise rCBV and k was found in four patients who had lesions with moderate k and vl elevation but no increase of rCBV. Results from this study suggest that in assessing the angiogenic activities in brain tumors it is advisable to monitor simultaneously changes in tumor blood volume, vessel permeability, and leakage space of tumor neovasculature.

Elongin (SIII): a multisubunit regulator of elongation by RNA polymerase II

The Elongin (SIII) complex activates elongation by mammalian RNA polymerase II by suppressing transient pausing of the polymerase at many sites within transcription units. Elongin is a heterotrimer composed of A, B, and C subunits of 110, 18, and 15 kilodaltons, respectively. Here, the mammalian Elongin A gene was isolated and expressed, and the Elongin (SIII) complex reconstituted with recombinant subunits. Elongin A is shown to function as the transcriptionally active component of Elongin (SIII) and Elongin B and C as regulatory subunits. Whereas Elongin C assembles with Elongin A to form an AC complex with increased specific activity, Elongin B, a member of the ubiquitin-homology gene family, appears to serve a chaperone-like function, facilitating assembly and enhancing stability of the Elongin (SIII) complex.
Dihalogenated trichodermin (4β-acetoxy-9,10-dibromo-12,13-epoxytrichothec)

In the title dihalogenated trichodermin molecule, C17H24Br2O4 (systematic name: 9,10-dibromo-12,13-epoxytrichothec-9-en-4β-yl acetate), the five-membered ring displays an envelope conformation, whereas the two six-membered rings show the same conformation, viz. chair. As for the seven-membered ring, the dihedral angle between the mean planes formed by the four C atoms of the envelope unit and the three C and one O atoms of the six-membered chair is 69.08 (4)°; these two mean planes are nearly perpendicular to the epoxy ring with angles of 87.53 (4) and 88.67 (4)°, respectively.
Effect of constraints on superpeer topologies

In superpeer based networks, the superpeers are discovered through the process of bootstrapping, whereby resourceful peers get upgraded to superpeers. However, bootstrapping is influenced by several factors like limitation on the maximum number of connections a peer can have due to bandwidth constraints, limitation on the availability of information of existing peers due to cache size constraints and also by the attachment policy of the newly arriving peers to the resourceful peers. In this paper, we derive closed form equations that model the effect of these factors on superpeer related topological properties of the networks. Based on the model, we observe that the cache parameters and the preferentiality parameters must be suitably tuned so as to increase the fraction of superpeers in the network. Finally, we perform an empirical analysis of social networks like Twitter and Facebook using our model to obtain and derive insights for suitably bootstrapping superpeer topology.

Evaluation of Oral Acyclovir Therapy

Acyclovir is a specific antiviral agent. The triphosphate form inhibits viral DNA replication by competing for incorporation into the replicating DNA chain or by inhibiting viral DNA polymerase. Cells not infected with herpesvirus are generally unaffected. Oral acyclovir inhibits most herpes simplex virus types 1 and 2, and varicellazoster virus at concentrations used clinically. Oral acyclovir has an average plasma half-life of three hours and is eliminated primarily by renal mechanisms. Peak plasma concentrations occur 1.5 to 2.5 hours after administration and the oral bioavailability is 15 to 30 percent. Acyclovir distributes into most body tissues, including vesicular fluid and the central nervous system. Oral acyclovir is effective treatment of initial and recurrent genital herpes and can suppress frequently recurring genital herpes in both immunocompetent and immunocompromised patients. It is also effective for acute herpes zoster in the immunocompetent and possibly immunocompromised patient. No role is established in either Epstein-Barr virus or cytomegalovirus infections. Oral acyclovir appears to be effective and relatively safe, nontoxic therapy when administered in doses of 1–4 g/d. Oral acyclovir represents a major therapeutic advance in the treatment of herpesvirus infections.
Criteria causing inconsistencies. General gluts as opposed to negation gluts

This paper studies the question: How should one handle inconsistencies that derive from the inadequacy of the criteria by which one approaches the world. I compare several approaches. The adaptive logics defined from CLuN appear to be superior to the others in this respect. They isolate inconsistencies rather than spreading them, and at the same time allow for genuine deductive steps from inconsistent and mutually inconsistent premises. Yet, the systems based on CLuN seem to introduce an asymmetry betweennegated and non-negated formulas, and this seems hard to justify. To clarify and understand the source of the asymmetry, the epistemological presuppositions of CLuN, viz. inadequate criteria, are investigated. This leads to a new type of paraconsistent logic that involves gluts with respect to all logical symbols. The larger part of the paper is devoted to this logic, to the adaptive logics defined from it, and to the properties of these systems. While the resulting logics are sensible and display interesting features, the search for variants of the justification leads to an unexpected justification for CLuN.
Influence of atrial fibrillation on microRNA expression 1 profiles in left and right atria from patients with valvular 2 heart disease 3 4 5 6

35 Chronic atrial fibrillation (AF) is a complication associated with the dilated atria 36 of patients with valvular heart disease and contributes to worsened pathology. We 37 examined microRNA (miRNA) expression profiles in right and left atrial appendage 38 tissue from valvular heart disease (VHD) patients. Right atrial appendage (RA) from 39 patients undergoing coronary artery bypass grafting (CABG) and left atrial (LA) 40 appendage from healthy hearts, not used for transplant, were used as controls. There was 41 no detectable effect of chronic AF on miRNA expression in LA tissue, but miRNA 42 expression in RA was strongly influenced by AF, with 47 miRNAs (15 higher, 32 lower) 43 showing differential expression between the AF and control sinus rhythm (SR) groups. 44 VHD induced different changes in miRNA expression in LA compared with RA. Fifty45 three (12 higher, 41 lower) miRNAs were altered by VHD in LA, compared with 5 (4 46 higher 1 lower) in RA tissue. miRNA profiles also differed between VHD-LA and VHD47 RA (13 higher, 26 lower). We conclude that VHD and AF influence miRNA expression 48 patterns in LA and RA, but these are affected differently by disease progression and by 49 the development of AF. These findings provide new insights into the progression of 50
Regional modelling of particulate matter with MADE

Describes the development and application of an aerosol model for regional air quality simulations. The aerosol model MADE is based on a modal concept and describes the chemical composition and the size distribution of atmospheric particulate matter. Primary as well as secondary aerosol components are considered in the model, which is fully integrated into the photochemical transport model EURAD. The model system has been applied to a European domain with different resolutions, using a one‐way nesting procedure. Simulations show the potential importance of secondary organics of anthropogenic and biogenic origin for the tropospheric particle loading. In addition it is shown that a reduction in precursor emissions for the inorganic ion fraction of PM (sulphate, nitrate and ammonium) does not necessarily lead to an equivalent reduction in PM2.5 mass concentrations, as for example a reduction in sulphate aerosol caused by reduced SO2 emissions might be compensated by enhanced formation of nitrate aerosols in certain regions.

Guanosine 5′‐diphosphate 3′‐diphosphate (ppGpp) as a negative modulator of polynucleotide phosphorylase activity in a ‘rare’ actinomycete

With the beginning of the idiophase the highly phosphorylated guanylic nucleotides guanosine 5′‐diphosphate 3′‐diphosphate (ppGpp) and guanosine 5′‐triphosphate 3′‐diphosphate (pppGpp), collectively referred to as (p)ppGpp, activate stress survival adaptation programmes and trigger secondary metabolism in actinomycetes. The major target of (p)ppGpp is the RNA polymerase, where it binds altering the enzyme activity. In this study analysis of the polynucleotide phosphorylase (PNPase)‐encoding gene pnp mRNA, in Nonomuraea sp. ATCC 39727 wild‐type, constitutively stringent and relaxed strains, led us to hypothesize that in actinomycetes (p)ppGpp may modulate gene expression at the level of RNA decay also. This hypothesis was supported by: (i) in vitro evidence that ppGpp, at physiological levels, inhibited both polynucleotide polymerase and phosphorolytic activities of PNPase in Nonomuraea sp. , but not in Escherichia coli, (ii) in vivo data showing that the pnp mRNA and the A40926 antibiotic cluster‐specific dpgA mRNA were stabilized during the idiophase in the wild‐type strain but not in a relaxed mutant and (iii) measurement of chemical decay of pulse‐labelled bulk mRNA. The results of biochemical tests suggest competitive inhibition of ppGpp with respect to nucleoside diphosphates in polynucleotide polymerase assays and mixed inhibition with respect to inorganic phosphate when the RNA phosphorolytic activity was determined.
Transitions of females from adolescent secure to adult secure services: A qualitative pilot project

Background: For young people, the transition from adolescent to adult services is particularly problematic. This may be particularly difficult for female service users. Aims: The aim of this study is to gain a fuller account of the experience of young people during transition from adolescent services to adult services and to add to the knowledge around the transitional process. Method: This study used a qualitative analysis of female adolescents' experience of transition to adult secure services. A four-layer coding structure grouped responses by time frame. Results: The results were consistent with previous research indicating that adolescents are sensitive to the behaviour of others throughout the transition process. Particularly, strong themes were the negative impact of aggression from other patients, the importance of relationships with staff and other patients, and the need for informed involvement in all aspects of the transition process. Conclusions: An increase in positive statements regarding the post-transition experience suggests that moves have been positive although this could be explained by admission to settings of lower security. The discussion highlights the importance of moving beyond procedural issues of transition to a focus on the social and culture gaps that appear to divide CAMHS and AMHS.
People tracking in a multi-camera environment

This paper presents a video processing system that can track a human target across multi-cameras. The user can browse video clips from the system. When a target is identified by the user, the system can automatically track the target across different cameras. There are three main parts in the system. The first part is object segmentation by a Bayesian model. The second part is object tracking. The mean-shift algorithm is used here to track the interested target in the current camera. The third part is cross-camera tracking. When the target is diminishing or moves out of the shooting range of the current camera, the system looks for the target in the neighboring camera. This part is repeated until the target is out of the shooting range of the multi-camera system. When initializing the system, the user can set up the relative positions and shooting angles of the cameras. The developed system is suitable for analyzing video clips from multiple surveillance cameras to track possible crime suspects. Experimental results on three outdoor surveillance cameras are presented and the results show that our approach is useful.
Daily variation of brain-derived neurotrophic factor and cortisol in women with normal menstrual cycles, undergoing oral contraception and in postmenopause.

BACKGROUND Plasma brain-derived neurotrophic factor (BDNF) levels are associated with the hormonal status of women. Moreover, the suprachiasmatic nucleus appears to be implicated in the modulation of BDNF central levels. We aimed to investigate whether BDNF circadian rhythms exist in women and if there is a relationship with cortisol circadian rhythmicity. Moreover, we aimed to establish whether the hormonal status influences BDNF diurnal variations. METHODS A total of 30 women were studied: 10 fertile ovulatory women, 10 women undergoing oral contraceptive (OC) therapy and 10 post-menopausal women. Basal BDNF and estradiol levels were assayed in blood samples collected after overnight fasting at regular intervals (08:00, 12:00, 16:00, 20:00, 24:00). BDNF and cortisol levels were measured in samples collected during the follicular and luteal phases in ovulatory women and once a month in OC and post-menopausal women. RESULTS Luteal BDNF levels were significantly higher than follicular levels in fertile women (P < 0.001). In OC women, BDNF levels were similar to the follicular BDNF levels, whereas in post-menopausal women, they were significantly lower (P < 0.001). BDNF showed a diurnal rhythm in the follicular phase and in women undergoing OC, although the diurnal rhythm was blunted in the luteal phase. In post-menopausal women, BDNF and cortisol levels significantly decreased during the day. CONCLUSIONS BDNF has a diurnal variation in women that is somewhat analogous to cortisol variation; however, the amplitude of the variation in BDNF levels appears to be influenced by ovarian function. Interactions between BDNF, the hypothalamus-pituitary-adrenal axis and sex steroids might play a critical role in the human homeostasis and adaptation.
