Investigating the climate impacts of global land cover change in the community climate system model
Authors: Lawrence Peter J. , Chase Thomas N. 
Published: January 2010

AbstractRecently, (Pitman et al., 2009) found a wide range of bio‐geophysical climate impacts from historical land cover change when modelled in a suite of current global climate models (GCMs). The bio‐geophysical climate impacts of human land cover change, however, have been investigated by a wide range of general circulation modelling, regional climate modelling, and observational studies. In this regard the IPCC 4th assessment report specifies radiative cooling of 0.2 W/m2 as the dominant global impact of human land cover change since 1750, but states this has a low to medium level of scientific understanding. To further contribute to the understanding of the possible climatic impacts of anthropogenic land cover change, we have performed a series of land cover change experiments with the community land model (CLM) within the community climate system model (CCSM). To do this we have developed a new set of potential vegetation land surface parameters to represent land cover change in CLM. The new parameters are consistent with the potential vegetation biome mapping of (Ramankutty and Foley, 1999), with the plant functional types (PFTs) and plant phenology consistent with the current day Moderate Resolution Imaging Spectroradiometer (MODIS) land surface parameters of (Lawrence and Chase, 2007). We found that land cover change in CCSM resulted in widespread regional warming of the near surface atmosphere, but with limited global impact on near surface temperatures. The experiments also found changes in precipitation, with drier conditions regionally, but with limited impact on average global precipitation. Analysis of the surface fluxes in the CCSM experiments found the current day warming was predominantly driven by changes in surface hydrology through reduced evapo‐transpiration and latent heat flux, with the radiative forcing playing a secondary role. We show that these finding are supported by a wide range of observational field studies, satellite studies and regional and global climate modelling studies.

AbstractSkeletal fracture healing involves a variety of cellular and molecular events; however, the mechanisms behind these processes are not fully understood. In the current study, we investigated the potential involvement of the signal transducer and activator of transcription 1 (STAT1), a critical regulator for both osteoclastogenesis and osteoblast differentiation, in skeletal fracture healing. We used a fracture model and a cortical defect model in mice, and found that fracture callus remodeling and membranous ossification are highly accelerated in STAT1‐deficient mice. Additionally, we found that STAT1 suppresses Osterix transcript levels and Osterix promoter activity in vitro, indicating the suppression of Osterix transcription as one of the mechanisms behind the inhibitory effect of STAT1 on osteoblast differentiation. Furthermore, we found that fludarabine, a potent STAT1 inhibitor, significantly increases bone formation in a heterotopic ossification model. These results reveal previously unknown functions of STAT1 in skeletal homeostasis and may have important clinical implications for the treatment of skeletal bone fracture. © 2010 Orthopaedic Research Society.

CE determination of secaloindoline allelic forms in hexaploid triticale (×Triticosecale Wittmack)
Authors: Salmanowicz Bolesław P. 
Published: January 2010

AbstractDifferences in kernel texture are mainly caused by specific secaloindoline (SIN) proteins occurring in friabilin fraction of hexaploid triticale (×Triticosecale Wittmack) grain. SINs were isolated using Triton X‐114 partitioning from either kernels/flour or starch of five triticale cultivars with wide range of different hardness. Crude SIN fraction was obtained by size‐exclusion HPLC. SINs were separated on an uncoated fused‐silica capillary using the iminodiacetic (IDA) buffer in conjunction with lower‐concentrated poly(ethylene oxide) and ACN. A low‐concentrate mixture of hydrophilic polymers, PVP and hydroxypropylmethylcellulose in IDA buffer was employed for dynamic coating of capillary inner wall. In total, on the basis of CZE profiles, two SIN‐a proteins and two SIN‐b proteins were identified. Allelic forms SIN‐a1 and SIN‐b1 have both two soft and one medium hard genotypes, however other allelic forms, designed as SIN‐a2 and SIN‐b2, were identified in hard and other medium hard cultivars. The CZE profiles showed that the ratio of the peak areas of SIN‐b proteins isolated from triticale starch can be preliminarily used to distinguish cultivars with soft and hard grain.
Preferential solvational effects on the Cr(VI) oxidation of benzylamines in benzene/2‐methylpropan‐2‐ol mixtures
Authors: Thirumoorthi A. , Bhuvaneshwari D. S. , Elango K. P. 
Published: January 2010

AbstractImidazolium fluorochromate (IFC) oxidation of 11 meta‐ and para‐substituted benzylamines, in varying mole fractions of benzene/2‐methylpropan‐2‐ol binary mixtures, is first order in IFC and acid and zero order in substrate. The Hammett correlation yielded a U‐shaped curve, indicating a change in the relative importance of bond formation and bond fission in the transition state. The rate data failed to correlate with macroscopic solvent parameters such as εr and E. The correlation of kobs with Kamlet–Taft solvatochromic parameters suggests that H‐bonding between the reacting species and the solvent plays a major role in governing the reactivity. © 2010 Wiley Periodicals, Inc.

The potential implications of web‐based marketing communications for consumers' implicit and explicit brand attitudes: A call for research
Authors: Madhavaram Sreedhar , Appan Radha 
Published: January 2010

AbstractTwo developments in the last two decades frame the importance of Web‐based marketing communications for firms. First is the phenomenal growth of the Internet as a viable commerce and communication option and second is the clear shift in attitude research toward recognizing the pervasive role of automatic processes in almost all the social psychological processes. Therefore, this article discusses the potential implications of Web‐based marketing communications for consumers' implicit and explicit attitudes. In doing so, first, this article reviews the emergence of research on implicit attitudes, distinguishes implicit attitudes from explicit attitudes, and discusses research on explicit and implicit attitudes relative to branding. Second, a brief discussion of marketing research on attitude is provided. Third, five empirically testable research propositions are developed and presented. Finally, given the potential implications for research and practice, the article concludes with a call for research. ©2010 Wiley Periodicals, Inc.
Skin cancer and Parkinson's disease

Published: January 2010

AbstractThe report of an increased frequency of melanoma during the clinical development of rasagiline prompted a renewed interest in a possible association between skin cancer and Parkinson's disease (PD). The evaluation of this risk ended in a recommendation to perform a periodic dermatological examination as a follow‐up measure of their treatment. The recognition of this safety concern lead to the need to clarify if the risk of skin cancer is indeed associated with PD and if levodopa or other anti‐parkinsonian drugs might contribute to increase such risk. To answer these questions, we critically reviewed all clinical studies available concerning the association between skin cancer and PD. We found 26 studies on cancer occurrence in PD. The best data available suggest the risk of cancer is reduced in PD patients. However, specific cancers like thyroid and the female breast were reported at higher‐than‐expected rates. Additionally, it was suggested that PD patients have a higher frequency of melanoma and non‐melanoma skin cancers than the general population. The data on non‐melanoma skin cancer are less robust than the data on melanoma. Causal factors remain unknown. Due to the weak association between skin cancer and PD, no robust recommendation can be made regarding the need for periodic dermatological screening. © 2010 Movement Disorder Society

Published: January 2010

AbstractTo investigate the health‐related quality of life (HrQoL) of adult patients with Gilles de la Tourette's syndrome (GTS) in Germany. HrQoL was evaluated in 200 adult patients with GTS (Mean age: 34.9 ± 11.8 years). Patients were recruited from three outpatient departments in Germany and completed a semi‐structured, self‐rating interview. HrQoL was measured using the EQ‐5D. Depression was assessed using the Beck's depression inventory (BDI) and clinical symptoms using the Yale Tourette syndrome symptom list (TSSL) and the Shapiro Tourette‐syndrome severity scale (STSSS). Multivariate regression analyses were performed to identify independent predictors of HrQoL. Patients with GTS proved to have a worse HrQoL than a sample from the general German population. The domains most affected were anxiety/depression (57.1%), followed by pain/discomfort (47.5%), usual activities (38.4%), mobility (14%), and self‐care (6.6%). The mean EQ‐5D visual analog scale (EQ‐VAS) was 65.4 ± 21.9. The patients had a mean BDI score of 12.3 ± 9.9, which was considerably worse compared to a healthy group who had a score of 6.45 ± 5.2. The mean STSSS value was 3.2 ± 1.1. In multivariate analyses, depressive symptoms contributed considerably, whereas the severity of symptoms as well as age only contributed minimally to HrQoL in the model (R2 = 0.54). HrQoL is considerably reduced in adult patients with GTS. The main independent factors for determining HrQoL were depression, severity of symptoms, and age. Although, treatment of tics is important, co‐morbidities such as depression should be diagnosed and treated vigorously. © 2009 Movement Disorder Society
Visual hallucinations and altered visual information processing in Parkinson disease and dementia with Lewy bodies

Published: January 2010

AbstractVisual hallucinations (VHs) are common in dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD), while auditory hallucinations are rare. To neurophysiologically investigate the pathophysiology of VHs in these disorders, we studied event‐related potentials (ERPs) of DLB, PDD, and Alzheimer's disease (AD) patients. We compared visual and auditory ERP latencies among PDD patients with and without VHs (PDD‐H: 11, PDD‐N: 6), DLB patients (24), and AD patients (21). To elicit visual and auditory ERPs, a facial discrimination paradigm and a conventional auditory odd‐ball paradigm, respectively, were used. The mean visual P3 latencies in the PDD‐H and DLB groups were significantly longer than that in the AD group, while the mean auditory P3 latencies in all four patient groups were comparable. The mean visual P2 latencies in the PDD‐N, PDD‐H, and DLB groups were significantly longer than that in the control group. Our findings suggest that visual cognitive functions are selectively impaired in hallucinatory patients with DLB and PDD. VHs may be associated in part with predominant visual cognitive impairments attributable to PDD and DLB pathologies. Our findings also suggest that the impairments occur at the early stage of facial information processing. © 2010 Movement Disorder Society

Published: January 2010

AbstractMusician's dystonia (MD) is a task‐specific movement disorder with a loss of voluntary motor control in highly trained movements. Defective inhibition on different levels of the central nervous system is involved in its pathophysiology. Cathodal transcranial direct current stimulation (ctDCS) diminishes excitability of the motor cortex and improves performance in overlearned tasks in healthy subjects. The aim of this study was to investigate whether ctDCS improves fine motor control in MD. Professional guitarists (n = 10) with MD played exercises before, directly after ctDCS, and 60 min after ctDCS. ctDCS (2 mA, 20 min) was applied on the primary motor cortex contralateral to the affected hand. Guitar exercises were video‐documented and symptoms were evaluated by three independent experts. No beneficial effect of ctDCS on fine motor control was found for the entire group. However, motor control of one guitarist improved after stimulation. This patient suffered from arm dystonia, whereas the other guitarists suffered from hand dystonia. © 2009 Movement Disorder Society

AbstractIn this letter, a dual‐band bandpass filter is proposed by consisting of spiral‐shaped microstrip resonators. Meanwhile, a skew‐symmetric tapped feed structure is applied to introduce two transmission zeros on both sides of individual passbands, and thereby improve the filter selectivity. The measured results of the designed third‐order dual‐band bandpass filter for 2.4/5.2 GHz wireless local area network applications are in good agreement with the simulated predictions. Moreover, the filter has a size reduction of 40%, as compared with the conventional square open‐loop bandpass filters. © 2010 Wiley Periodicals, Inc.

Published: January 2010

AbstractWe propose a scheme to improve the transmission efficiency of radio over fiber system, which is to constitute a local area optical network with many micro cell base stations centering on the remote node. All the data switching among base stations within this optical network will be realized by the wavelength allocation module of the remote node instead of the central office. Such a method has the advantage of economize the capacity of the backbone fiber between the center office and the remote node, therefore increases the transmission efficiency of the system. © 2010 Wiley Periodicals, Inc.

Autofocusing imaging through the unknown building wall with EM inverse scattering algorithm
Authors: Zhang Wenji , Li Lianlin , Li Fang 
Published: January 2010

AbstractThe through‐wall imaging (TWI) problem is studied within the context of EM inverse scattering in this article.A novel real time TWI algorithm is proposed by employing the spectrum Green's function and exploding source model under Born approximation. The complex scattering process because of the presence of the wall is well modeled in the imaging formulation through the layered medium Green's function. Inspired by the concept of time reversal imaging, a novel autofocusing strategy is incorporated in the proposed algorithm. The autofocusing is achieved by introducing a time factor in the TWI formulation to get a dynamic image at different focusing time. The image at the time instant, when the defined entropy is minimized, is stored as the output of the imaging result. Numerical and experimental results are presented to show that the proposed method can provide high quality focused image in a short computation time regardless of the estimated value of the wall parameters. © 2010 Wiley Periodicals, Inc.

Published: January 2010

AbstractA compact quad‐band RF front‐end module (FEM) is proposed for Wi‐Fi and WiMAX dual‐mode systems using film bulk acoustic resonator (FBAR) and low temperature co‐fired ceramic (LTCC) technologies. The quad‐band RF FEM consists of three LTCC bandpass filters, two diplexers, one FBAR filter, two single‐pole‐double‐throw switches, and one single‐pole‐four‐throw switch. The diplexers with the bandpass filters for each mode are fully embedded in the LTCC substrate, whereas the FBAR filter and three RF switches are placed on top of the substrate. The measured performance of the embedded diplexers with the bandpass filters is compared to the simulated one, resulting in good agreement between both performances. The implemented quad‐band RF FEM provides relatively low insertion loss with high attenuation at other passband for each mode. The overall size of the module is 6.0 mm × 5.0 mm with a substrate thickness of 0.6 mm. © 2010 American Association of Anatomists Microwave Opt Technol Lett 52: 753–757, 2010; Published online in Wiley InterScience (www.interscience.wiley.com).
