Determinants of Involvement in Mobile Commerce: The Moderating Role of Gender

Mobile phones are one of the latest marketing tools that consumers are using to make their purchases, a fact that entails a evolution in the way firms are relating to their clients. It therefore becomes essential to understand the driving forces behind consumer involvement in this purchase channel; an aspect that has not been previously studied in the context of mobile commerce. In this pioneering work, we analyze the role that is played by perceived risk in mobile purchasing, permission marketing and consumer propensity towards new technologies as antecedents of consumer involvement. Based on the information gathered from a sample of 674 mobile users, our work highlights the importance of these variables as facilitators of involvement, as well as the need for firms to consider gender differences in the development of their strategies.
Low cost dual-polarized suspended microstrip antenna array for 5.8 GHz point-to-point links

In this paper, a dual-polarized microstrip array antenna with simple feeding network is proposed. The antenna consists of a single low cost substrate suspended over metallic ground plate. The dual polarization performance was achieved by means of smart combination of two single polarized antennas. A prototype of the antenna was manufactured and the results obtained by measurements and simulations were compared with very good agreement.
Resources and Opportunities Large-Scale Profiling of the Arabidopsis Transcriptome

DNA microarray is a powerful technology for parallel analysis of gene expression (Brown and Bostein, 1999). Since microarray technology emerged 5 years ago (Schena et al., 1995), the number of genes that can be monitored by this technology has increased from several hundreds (Yuan et al., 1998; Aharoni et al., 2000; Reymond et al., 2000) to several thousands (Arabidopsis Functional Genomics Consortium Microarray, http://afgc.stanford.edu/afgc html). At Novartis Agricultural Discovery Institute, Inc. (NADII), microarray is an important component in our toolbox for transcription profiling. In addition, we have developed and are using other gene expression monitoring technology platforms for gene expression profiling (emphasizing coverage) and gene expression diagnostics (emphasizing throughput). These technologies include serial analysis of gene expression, cDNA fingerprinting, and microbead-based liquid microarray. Here we focus on the microarray technologies used at NADII. It should be noted that there are at least two nomenclature systems that have been used to describe the hybridization partners in the microarray field. Consistent with the common nomenclature (Duggan et al., 1999; Lipshultz et al., 1999; Southern et al., 1999), we use “probe” to refer to the tethered nucleic acid molecules used to interrogate the experimental samples and “target” to refer to the free hybridization partner in the experimental sample. Our gene expression microarray program has two technology platforms: oligonucleotide-based probe array (GeneChip) and cDNA-based array. For the purpose of gene discovery using Arabidopsis as a model system, a large-scale profile of its transcriptome is needed. We selected the oligonucleotidebased array (Lockhart et al., 1996) as our primary platform technology because of the following reasons. First, the transcript abundance of each gene can be accurately measured by multiple probe pairs. Second, the data can be produced with a moderate throughput and a large scale. The designed arrays are commercially manufactured using photolithography technology, therefore, the time-consuming and labor-intensive array fabrication process is eliminated. Moreover, human errors that often occur during the clone tracking process are also eliminated. Third, standardized data produced by the array can be easily normalized and interrogated. This is important when cross-project comparison is needed. And finally, the necessary genomic information for oligonucleotide probe selection is available from the Arabidopsis genome sequencing project (Lin et al., 1999; Mayer et al., 1999). To profile the Arabidopsis transcriptome on a large scale, in addition to designing a high-density oligonucleotide probe array, we also tested and developed protocols for sample preparation; we developed the laboratory information management system (LIMS) for project, sample information, and data management; and we developed and integrated a number of analysis tools for data mining.
Perinatal Risk Factors for Neonaticide and Infant Homicide: Can we Identify those at Risk?

Infant homicide is a legal term that refers to killing of a child in the first year of life. Infanticide, as defined by the Infanticide Act, is when a mother ‘causes death of her child under the age of 12 months by wilful act or omission, but at the time of the act or omission the balance of her mind was disturbed by reason of her not having fully recovered from the effect of her having given birth to the child or by reasons of the effect of lactation consequent on the birth of the child’. Neonaticide is not specifically defined by the Infanticide Act, but in medical publications usually refers to the killing of a child during the first 24 hours of life. 2
Assessment of clinical activity of E7080, a multitargeted kinase inhibitor, in patients with advanced melanoma treated in two phase I trials.

8527 Background: E7080 is an oral tyrosine kinase inhibitor targeting VEGFR1-3, FGFR1-4, RET, KIT and PDGFRβ. In phase I studies of E7080, DLTs were hypertension and proteinuria and common toxicities included grade 1-2 fatigue, anorexia, nausea, weight loss and diarrhea. MTD for E7080 once daily (QD) is 25 mg and for twice daily (BID) is 20 mg (i.e.10 mg BID). METHODS From 7/2005 to 10/2008, 82 patients (pts) with advanced solid tumors including 14 with advanced melanoma were enrolled into a phase I study of escalating doses of E7080 QD. From 7/2005 to 8/2009, 77 pts with advanced solid tumors including 29 with advanced melanoma were enrolled into a second phase I study of escalating doses of E7080 BID. 25/29 pts receiving E7080 BID underwent pretreatment biopsy for molecular analysis of tumor vascular and melanoma cell components. Those results are reported separately. Clinical outcomes for melanoma pts treated with E7080 in phase I trials are reported. RESULTS 35/43 pts received E7080 doses of ≥ 20 mg/day. 5/14 pts receiving E7080 QD had tumor reductions of 20% to 85%, including 2 confirmed PRs. Median progression free survival (PFS) was 7 months. 6 mo PFS was 58%. 7/29 pts receiving E7080 BID, had tumor reductions of 20% to 85% including 3 confirmed PRs. Median PFS for this group was 3.6 months, 6 mo PFS was 25%. For all pts treated in both trials median PFS was 4 mo (95% CI: 3.4-7.1). 6 mo PFS was 35%. Median duration of PR was 15 mo (range: 5-23 mo). CONCLUSIONS E7080 administered to pts with advanced melanoma in two phase I studies achieved PRs and prolonged tumor regression in a subset of patients. Pts receiving QD doses of E7080 ≥20 mg/day appear to have longer PFS compared to pts receiving QD E7080 doses <20 mg/day. A phase II trial is currently ongoing to determine the magnitude of the treatment effect in molecularly defined populations and to identify the molecular features of E7080 responsive melanomas.
A miniaturized LTCC bandpass filter with low insertion loss and high image rejection within 6.5 to 7.1GHz frequency range

A low-temperature-cofired ceramic (LTCC) bandpass filter with low insertion loss and high image rejection is presented for super heterodyne microwave receiver within 6.5–7.1GHz band. By improving the filter cell structure, two transmission zeros can be generated to achieve wide-band image suppression from cascading filter cells. The presented method provides the design flexibility of locating these transmission zeros distributed in the lower and upper stopbands. To reduce insertion loss and size of the filter, a miniaturized LTCC three-stage bandpass filter with two transmission zeros in lower stopband has been implemented for experimental demonstration. The measured insertion loss is less than 1.0 dB at 6.8GHz, the measured image rejection from 5 to 5.6GHz is more than 42dB, the input/output VSWR is less than 1.5. The size of the miniaturized filter is only 2.5mm×2mm×1.2mm. The process yield of the LTCC filter is more than 90%.
Investigation of the Presence and Protective Effects of Maternal Antibodies Against Campylobacter jejuni in Chickens

Abstract The role of maternal antibodies in the lag phase of Campylobacter positivity, widely observed in commercial broiler flocks, was investigated. The results indicate that 3-wk-old birds derived from a commercial flock are more susceptible to colonization with Campylobacter jejuni than 1-to-2-wk-old birds. This increasing susceptibility parallels the loss of maternally derived, circulating, anti-Campylobacter, immunoglobulin Y antibodies as detected by enzyme-linked immunosorbent assay. The role of these antibodies in resistance to colonization was further investigated using progeny from breeder flocks of known Campylobacter status. These results confirmed that maternal antibodies confer partial protection against Campylobacter colonization on young chickens (1–2 wk old). This protection was directed against challenge with both homologous and heterologous strains of C. jejuni and even against strains with a high colonization potential. However, evidence presented indicates that newly hatched chicks, with the highest levels of maternal antibodies, were as susceptible to Campylobacter challenge as 3-wk-old birds. This conundrum was investigated further, and an increase in resistance was detected from 1 to 3 days of age. The reasons for this are, as yet, unknown, but the observation validates the use of newly hatched chicks in models of Campylobacter colonization. Moreover, this high susceptibility in the first few days of life may explain the occasional early flock colonization observed, especially when environmental exposure to Campylobacter is high, for example, in free-range birds.
Clinical, Biochemical, and Ovarian Morphologic Features in Women With Acanthosis Nigricans and Masculinization

Nine women with acanthosis nigricans and masculinization, who did not appear to have any of the reported syndromes associated with acanthosis nigricans, were studied to characterize the clinical, biochemical, and ovarian morphologic features of their disorders. These patients had the clinical and biochemical profiles of polycystic ovarian disease. All acanthosis nigricans subjects had significant insulin resistance when insulin binding to both circulating monocytes and erythrocytes was compared to the control subjects. Microscopic examination of the ovaries revealed no evidence of recent normal ovulation, sclerosis of the ovarian cortex, follicle cysts, and stromal hyperthecosis. The authors conclude that ovarian stromal hyperthecosis and insulin resistance are consistent findings in the present type of patient. This study provides further evidence supporting a relationship between insulin resistance and human ovarian function.
[Detection of 3 anaerobic microorganisms in saliva and subgingival plaque of patients with periodontitis].

OBJECTIVE To investigate the prevalence of 3 anaerobic microorganisms including Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf) and Treponema denticola (Td) in saliva and pooled subgingival plaque of different types of periodontitis and compare the detections of three microorganisms between saliva and pooled subgingival plaque sample from the same patient, and analyze the relationship between prevalence of these pathogens in saliva and periodontal parameters. METHODS Non-stimulated saliva samples and pooled subgingival plaque samples were collected from 50 patients with aggressive periodontitis (AgP), 48 patients with chronic periodontitis (CP) and 25 subjects with no periodontitis, and three microorganisms including Pg, Tf and Td were detected in these samples by PCR method. RESULTS Prevalence of three microorganisms in pooled subgingival plaque and saliva samples of AgP patients and CP patients were significantly higher than subjects with no periodontitis (P<0.01). The prevalence of Pg in Subgingival plaque and saliva was as follows: AgP, 100% vs 100%; CP, 93.8% vs 93.8%; Subjects with no periodontitis, 32% vs 48%. The prevalence of Tf in Subgingival plaque and saliva was as follows: AgP, 96% vs 88%; CP, 97.9% vs 89.6%; Subjects with no periodontitis, 32% vs 24%. The prevalence of Td in Subgingival plaque and saliva was as follows: AgP, 94% vs 86%; CP, 89.6% vs 70.8%; Subjects with no periodontitis, 12% vs 16%. The agreement between saliva and pooled subgingival plaque samples of these three microorganisms from the same patient was high. The presence of three microorganisms in saliva was all associated with bleeding index of gingiva, and odds ratio of Pg was 13.5 (P<0.01). CONCLUSION Pg, Tf and Td were widely distributed in saliva and subgingival plaque of patients with AgP and CP. Presence of Pg, Tf and Td in saliva was related to periodontal parameters of gingiva, and saliva could be used as a promising sample for oral detection of these 3 microorganisms.
A three-dimensional finite element analysis of a porous rooted Co-Cr-Mo alloy dental implant.

A three-dimensional finite element model was used to investigate the biomechanical response of a porous rooted Co-Cr-Mo alloy implant. The load displacement responses calculated from the finite element model were verified with experimentally-determined values for three-cylindrical, porous rooted Co-Cr-Mo alloy dental implants retrieved from canines after two years in function. Models were developed based on histological analyses of tissue surrounding the implants. The results of the study indicate that the assumption of a direct bone-to-implant interface (i.e., an ankylosed implant) may not be a good representation for a porous rooted implant retained by bone ingrowth.
Atypical retinitis pigmentosa masquerading as primary open angle glaucoma.

To the Editor: We would like to congratulate Lin et al on their case report in which they were able to diagnose, using electroretinogram, atypical retinitis pigmentosa (RP) in a patient initially diagnosed as having primary open angle glaucoma. The authors described a patient with the provisional diagnosis of primary open angle glaucoma who had been on multiple glaucoma medications. The patient was recognized as having nonprogressive visual field defects for more than 5 years. The authors carried out a complete ophthalmic examination including normal corrected visual acuity for a myope, pressures of 25mm Hg OD and 17mm Hg OS, no optic nerve cupping, and from the photographs an optic cup disc ratio of 0.35 OD and 0.2 OS, with bilateral temporal beta zone peripapillary atrophy. Study of the retina shown in the color photographs demonstrates pigmentation to be imperceptible. Not only that, but the retinal veins of this healthy 60-year-old man seemed to be of larger than normal caliber. Considering that he was systemically well, one would have expected that these represented smokers’ veins. Further, the prominently large arteriolar and venular caliber is quite unlike what is found in well established RP. Visual field assessment demonstrated bilateral nasal and temporal, superior, and inferior defects. Given that the patient had RP for at least 5 years, the defects do not look typical of the ring scotoma of RP. As his retinal vessels and optic nerves were normal and the only abnormality apart from the fields was the right ocular hypertensive eye, our group would not have diagnosed RP. Working as we do in a comprehensive general tertiary referral hospital, a patient with abnormal visual fields with no obvious explanation for them would be submitted to neuroradiologic assessment, with magnetic resonance imaging being the modality of choice. Even if glaucoma is the suspected culprit, an article by Kashiwagi et al in this journal highlighted the advantageous nature of magnetic resonance imaging as an objective measure for evaluating glaucomatous damage. We further suggest that a complete ophthalmologic history and examination should include investigation for systemic causes of bilateral visual field defects such as vitamin A deficiency, cancer-associated retinopathy, psychogenic visual loss, and abetalipoproteinaemia. Therefore, historical evidence regarding dietary deficiencies and basic hematologic and biochemical workup are reasonable. As highlighted by the authors, accurate diagnosis and subsequent appropriate treatment for any patient with bilateral visual field defects atypical for glaucoma require thorough evaluation including appropriate investigations and imaging.
The origin of 47,XXY and 47,XXX aneuploidy: heterogeneous mechanisms and role of aberrant recombination.

We investigated the parent and cell division of origin of the additional sex chromosome in 142 males with a 47,XXY constitution and 50 females with a 47,XXX constitution. In 66 of the 47,XXY males the additional chromosome was paternal in origin and in 76 it was maternal in origin, while among the 47,XXX females only 5 had an additional paternal X chromosome, the remaining 45 having an additional maternal chromosome. Among the 107 maternally derived aneuploids for whom it was possible to determine the cell division of origin, 73 were the result of a mat MI error, 24 the result of a mat MII error and 10 the result of a post zygotic mitotic (PZM) error involving the maternal X chromosome. Among those in which the non-disjunction was attributable to an error at the first meiotic division (MI) we observed three different mechanisms of origin. Approximately 30% were associated with complete absence of recombination (nullichiasmate); approximately 24% were associated with a normal number of recombinant events but an abnormal distribution of exchanges (perturbed recombination), while approximately 45% were associated with a normal number and distribution of recombinant events (normochiasmate). Nondisjunction due to an error at the second meiotic division (MII) was associated with a slight reduction in the total number of recombinant events and an abnormal distribution of exchanges. Thus of the four different meiotic mechanisms of origin, three were associated with an abnormal number and/or distribution of exchange events. There was no evidence of an increased paternal age in the aneuploids of paternal origin. (ABSTRACT TRUNCATED AT 250 WORDS)
A Monotonic Digitally Controlled Oscillator with Self-Calibration in 65 nm CMOS Technology

This paper presents a self-calibration circuit to correct the non-monotonic response in the cascading digitally controlled oscillator (DCO). The proposed calibration circuit can solve the non-monotonic problem when the coarse-tuning control code is changed. The proposed DCO implemented with a standard performance 65nm CMOS process can output frequency ranges from 58.7 MHz to 481.6 MHz. And the total power consumption of the DCO with calibration circuit is 0.142 mW at 58.7 MHz and is 0.205mW at 481.6MHz. The proposed DCO with calibration circuit is easy to be implemented and thus is very suitable for ADPLL design in SoC applications.
Effects of tillage on soil physical properties and root growth of maize in loam and clay in central China

Soil compaction of agricultural soils is a global well recognized problem (Hamza and Anderson 2005) due to deteriorated soil environment and adverse effects of intensive use of farm machinery on crop yield (Hamza et al. 2011). In China, subsoil compaction is also caused by inappropriate tillage, traffic and field operations on poor time (Zhang et al. 2006). According to our investigation in 2008, the average soil bulk density at 5–10 cm depth is 1.38 t/m 3 , while the average soil bulk density at the plowpan is 1.52 t/m 3 in central China. The soil bulk density is much higher than the proper soil bulk density for maize which is 1.2–1.3 t/m 3 (Li and
Divergence and Convergence of Organisational Forms: An Analysis of the Structuring of the Danish IT Field

The structuring of the Danish IT field since its emergence in the fifties is analysed. The analysis deals with both the Danish IT people and IT organisations (suppliers as well as intermediaries and users). Seven IT communities representing different configurations of tasks, actors, and value systems are identified as the main constituents of the Danish IT field. The emergence of these institutions is explained as a consequence of processes of institutionalisation, comprising: interaction between a community and its environment, IT field interaction,
Production of proinflammatory cytokines by resident tissue macrophages after phagocytosis of apoptotic cells.

It is generally believed that apoptosis is not associated with inflammation. However, we have found that phagocytosis of apoptotic cells by PMA-treated THP-1 cells and human monocyte-derived macrophages led to the production of proinflammatory cytokines, notably IL-8. These macrophages were obtained either by PMA treatment or by M-CSF treatment, possibly affecting the cytokine production after phagocytosis of apoptotic cells. In order to exclude the possibility, we employed resident tissue macrophages such as Kupffer cells and alveolar macrophages in this study and examined the production of cytokines after phagocytosis of apoptotic cells. Kupffer cells produced proinflammatory cytokines MIP-2 and TNF-alpha at the mRNA level. The MIP-2 protein was also detected by means of ELISA. Alveolar macrophages also produced the MIP-2 protein after phagocytosis of apoptotic cells. Furthermore, apoptotic thymocytes induced a similar response by these macrophages. These findings do support the notion that macrophages are apt to produce proinflammatory cytokines after phagocytosis of apoptotic cells.
Inkjet printed ferrite-filled rectangular waveguide X-band isolator

For the first time, a rectangular waveguide (RWG) isolator realized through inkjet printing on a ferrite substrate is presented. Yttrium iron garnet (YIG) substrate is used for the realization of the ferrite-filled isolator. Contrary to the substrate integrated waveguide (SIW) approach, all four walls of the waveguide have been inkjet printed on the YIG substrate demonstrating the utility of inkjet printing process for realizing non-planar microwave components. The isolation is achieved by applying an anti-symmetrical DC magnetic bias to the ferrite-filled waveguide which then exhibits a unidirectional mode of operation. The isolator is fed by a microstrip to RWG transition and demonstrates an isolation figure-of-merit (IFM) of more than 51 dB in the operating band from 9.95 GHz to 11.73 GHz with a very high peak IFM of 69 dB. The minimum insertion loss in the operating band is 2.73 dB (including losses from the transitions). The isolator measures 33 mm × 8 mm × 0.4 mm. This work introduces an inkjet printed non-planar microwave device which is easy to fabricate showing the ability of inkjet printing for fabricating complex microwave systems.
Noise performance scaling in high-speed silicon RF technologies

SiGe HBT technology has evolved rapidly during the past several years through both scaling and structural enhancements, with each contributing to improved low-noise performance. Vertical scaling has increased f/sub T/ by 4/spl times/ between the 0.5 /spl mu/m and 0.13/spl mu/m generations, contributing to a 2.5 dB drop in noise figure at 26 GHz. At the same time, both lateral scaling as well as the move to a raised-extrinsic-base structure have reduced R/sub B/ by 4.5/spl times/, contributing an additional 1 dB F/sub min/ drop. The resulting 200GHz SiGe HBT achieves F/sub min/ and G/sub A/ values of 1.1 dB and 9 dB at 26 GHz, respectively, with a projected F/sub min/ of 3.1-3.5 dB at 60 GHz. Such performance suggests that silicon enjoys great potential to serve a range of emerging wireless applications at high frequencies.
