Sub-Micron Area Heterojunction Backward Diode Millimeter-Wave Detectors With 0.18 ${\rm pW/Hz}^{1/2}$ Noise Equivalent Power

InAs/AlSb/AlGaSb heterojunction backward diodes are promising detectors for millimeter-wave imaging applications due to their high sensitivity, low noise, and high cutoff frequency. By using a device heterostructure with a thin (11 Å) barrier layer, δ-doped cathode, and optimized Al<sub>x</sub>Ga<sub>1-x</sub>Sb anode composition (x=12%), in conjunction with submicron (0.4×0.4 μm<sup>2</sup>) active area, fabricated detectors have demonstrated DC curvatures of -47 V<sup>-1</sup> and record unmatched sensitivities of 4600 V/W at 94 GHz. Impedance-matched sensitivities of 49,700 V/W at 94 GHz are projected from on-wafer S-parameter and sensitivity measurements. These detectors have measured junction resistances of 814 Ω·μm<sup>2</sup> and capacitances of 15 fF/μm<sup>2</sup>. A record low NEP<sub>min</sub> of 0.18 pW/Hz<sup>1/2</sup> has been projected under conjugate matching conditions. This study demonstrates the potential of Sb-heterostructure backward diodes as ultra-low-noise millimeter-wave direct detectors.
Interpretative perspectives on the acceptance of an optional information system

Understanding the factors that contribute to the acceptance and use of information systems is a central concern in the field of information systems. Especially in cases where users are relatively free to use an information system (a so called optional information system) it is important for implementers to understand which factors determine acceptance in order to develop an effective design and implementation plan. In order to identify factors that determine acceptance, this report describes and analyses the implementation of a therapy expert system for general practitioners (GPs) in the Netherlands. The Netherlands Ministry of Health decided to implement this system with the objective to promote cost effectiveness, consistency and quality of therapies and drug prescriptions of general practitioners. This paper uses an interpretive perspective to analyze the limited acceptance of the system. While the promotion campaign focused on the system, GPs based their decision on wider contextual factors. The case demonstrates pitfalls, which come up during the implementation of such a system, and shows which factors may play a role in the decision of possible users to accept or reject such an optional information system. Different issues arise from this case. One is that users seem to differ from non-users and that perceptions about the system itself but also about non-system features affect the decision to accept. The paper uses the evidence of the case by suggesting to extend the technology acceptance model (TAM) with relevant contextual factors. It concludes by outlining its implications for implementers of optional information systems in general.
The impact of social cues and effectiveness in check-in advertising

Purpose – Check-in based advertising is growing dramatically as the popularity of social media increases. The purpose of this paper is to explore which social cues are appropriate for check-in based advertising in social media based on media richness theory and how content effectiveness affects content generation intention based on achievement motivation theory. Design/methodology/approach – A laboratory experiment was performed to evaluate the effects of social cue strategies on content effectiveness of attitude toward the ad and self-efficacy on recall. The influence of effectiveness on content generation intention are also measured in the experiment. Findings – The results of a laboratory experiment indicated that a strategy of using plentiful social cues has high effectiveness as measured by the concept of attitude toward the ad. Content effectiveness measured by attitude toward the ad and self-efficacy on recall can directly affect user intentions to generating check-in based advertisements. Research.
Involvement of Epidermal Growth Factor Receptor Signaling in Estrogen Inhibition of Oocyte Maturation Mediated Through the G Protein-Coupled Estrogen Receptor (Gper) in Zebrafish (Danio rerio)1

Oocyte maturation (OM) in teleosts is under precise hormonal control by progestins and estrogens. We show here that estrogens activate an epidermal growth factor receptor (Egfr) signaling pathway in fully grown, denuded zebrafish (Danio rerio) oocytes through the G protein-coupled estrogen receptor (Gper; also known as GPR30) to maintain oocyte meiotic arrest in a germinal vesicle breakdown (GVBD) bioassay. A GPER-specific antagonist, G-15, increased spontaneous OM, indicating that the inhibitory estrogen actions on OM are mediated through Gper. Estradiol-17beta-bovine serum albumin, which cannot enter oocytes, decreased GVBD, whereas treatment with actinomycin D did not block estrogen's inhibitory effects, suggesting that estrogens act at the cell surface via a nongenomic mechanism to prevent OM. The intracellular tyrosine kinase (Src) inhibitor, PP2, blocked estrogen inhibition of OM. Expression of egfr mRNA and Egfr protein were detected in denuded zebrafish oocytes. The matrix metalloproteinase (MMP) inhibitor, ilomastat, which prevents the release of heparin-bound epidermal growth factor, increased spontaneous OM, whereas the MMP activator, interleukin-1alpha, decreased spontaneous OM. Moreover, inhibitors of EGFR (ErbB1) and extracellular-related kinase 1 and 2 (Erk1/2; official symbol Mapk3/1) increased spontaneous OM. In addition, estradiol-17beta and the GPER agonist, G-1, increased phosphorylation of Erk, and this was abrogated by simultaneous treatment with the EGFR inhibitor. Taken together, these results suggest that estrogens act through Gper to maintain meiotic arrest via an Src kinase-dependent G-protein betagamma subunit signaling pathway involving transactivation of egfr and phosphorylation of Mapk3/1. To our knowledge, this is the first evidence that EGFR signaling in vertebrate oocytes can prevent meiotic progression.
Supply chains and supply networks: distinctions and overlaps

Purpose – Although supply chain management is now an established field, the distinction between supply chains and supply networks is relatively immature and requires further investigation. The purpose of this paper is to clarify the distinction between supply chains and supply networks. Design/methodology/approach – Based on a review of the literature and assisted by input from academic experts during a relevant supply chain management workshop, this paper critiques seminal and extant theoretical developments in the field of supply chain management. Findings – The main contribution of this paper is the development of an outline classification of relevant dimensions where the concepts of supply chain and supply network are compared and their distinctive features are highlighted. The paper identifies strategic opportunities emanating from considering both the supply chain and supply network, and the associated levels of engagement with active and inactive members in terms of, inter alia, complexity, members.
Immunolocalization of Intermediate Filaments and Laminin in the Oviduct of the Immature and Mature Japanese Quail (Coturnix coturnix japonica)

This study describes the distribution of vimentin, desmin, smooth muscle actin (SMA) and laminin in the oviduct of the immature and mature Japanese quail. The cytoskeletal proteins vimentin, desmin and SMA have been shown to be involved in cellular support, differentiation, migration and contractility. Laminin is a major component of basement membranes. Luminal epithelia in the infundibular and magnal regions of immature and mature birds exhibited strong vimentin immunoreactivity. Luminal epithelial cells exhibiting strong vimentin immunoreactivity were present in the isthmus and shell gland regions of only mature quails. Infundibular glandular grooves displayed strong vimentin immunostaining. In contrast, the glandular epithelia of the magnum, isthmus and shell gland were vimentin immunonegative. Fibroblasts and vascular endothelial cells in the lamina propria of the oviductal regions studied exhibited strong vimentin immunostaining. Smooth muscle cells forming the tunica muscularis and vascular tunica media displayed strong desmin and SMA immunostaining. Strong laminin immunostaining was demonstrated in the basement membranes associated with smooth muscle cells, as well as in the basement membranes underlying the luminal and glandular epithelia. In conclusion, this study has shown that the immunolocalization of desmin, SMA and laminin in the oviduct of the Japanese quail is similar to that in the domestic fowl. However, differences in the immunoexpression of vimentin in the LE of the two avian species were shown to exist. In addition, the study has shown that the immunolocalization of vimentin in the Japanese quail varies depending on the oviductal region, as well as the developmental stage of the oviduct.
Antecedents and implications of search engine use as prepurchase information tools

The aim of this research is to analyse the antecedents and implications of using search engines as prepurchase information tools. The impact of internet use experience, internet shopping experience and online shopping motivations on the use of information provided by search engines in online purchases is analysed together with attitudinal changes deriving from search engine use (online purchase intention). Data analysis shows that the experiences as internet user and as internet shopper are negative key drivers of search engine use. The use of search engines in online purchase decisions is more likely in consumers with utilitarian shopping motivations than in consumers with hedonic shopping motivations and it predicts online purchasing behaviour. This research enables companies to know the factors that potentially affect search engine use in e-shopping decisions and the importance of using search engines in their communication campaigns. Internet agents should exploit the advantages that search engines offer to facilitate the online purchasing process.
Characteristics of COPD patients according to GOLD classification and clinical phenotypes in the Russian Federation: the SUPPORT trial

Background The high prevalence of COPD in the Russian Federation has been demonstrated in several epidemiological studies. However, there are still no data on the clinical characteristics of these patients according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) groups and phenotypes, which could provide additional understanding of the burden of COPD, routine clinical practice, and ways to improve the treatment of patients with COPD in Russia. Patients and methods SUPPORT was an observational multicenter study designed to obtain data about the distribution of patients with previously diagnosed COPD according to the severity of bronchial obstruction, symptom severity, risk of exacerbation, COPD phenotypes, and treatment of COPD. We included patients with a previous diagnosis of COPD who visited one of 33 primary-care centers for any reason in 23 cities in Russia. Results Among the 1,505 patients with a previous diagnosis of COPD who attended the primary-care centers and were screened for the study, 1,111 had a spirometry-confirmed diagnosis and were included in the analysis. Up to 53% of the patients had severe or very severe COPD (GOLD stages III–IV), and 74.3% belonged to the GOLD D group. The majority of patients were frequent exacerbators (exacerbators with chronic bronchitis [37.3%], exacerbators without chronic bronchitis [14%]), while 35.8% were nonexacerbators and 12.9% had asthma–COPD overlap. Among the GOLD D group patients, >20% were treated with only short-acting bronchodilators. Conclusion COPD is still misdiagnosed in primary care in Russia. COPD patients in primary care are usually GOLD D with frequent exacerbations and are often treated with only short-acting bronchodilators.
Spacing-Switchable Multiwavelength Fiber Laser Based on Nonlinear Polarization Rotation and Brillouin Scattering in Photonic Crystal Fiber

A new spacing-switchable multiwavelength erbium-doped fiber laser (EDFL) is demonstrated using switchable nonlinear polarization rotation (NPR) and stimulated Brillouin scattering (SBS) effects. The laser employs a 100-m-long photonic crystal fiber in conjunction with a four-port circulator in a figure-of-eight arrangement to provide the intensity-dependent transmission effect, as well as to discriminate the even-order and odd-order Brillouin Stokes to have a double-frequency Brillouin Stokes output. Without the Brillouin pump (BP), the laser operates in an NPR mode to produce at least 22 lasing wavelengths with a side mode suppression ratio of more than 10 dB and a wavelength spacing of 0.27 nm. In the Brillouin erbium fiber laser mode, at least 30 Brillouin lines with a spacing of 0.16 nm are obtained at BP power of 3 dBm and 980-nm pump power of 120 mW.
Blind Adaptive Shift Length Watermarking For Digital Images

In recent years, as a result of the development of the network and popularization of the multimedia information, watermark technology has been utilized for ensuring the copyright of digital information. This paper proposed a new blind watermarking algorithm for discrete cosine transform (DCT) based digital images. In the proposed method, the differences of DCT coefficients between original and watermarked information were calculated and performed to determine the adjustment of the watermarked DCT coefficients. Simulation results show that the proposed watermark algorithm not only provided similar robustness as previous watermarking investigations but also improved image quality of the watermarked image and the quantity of hiding information. Moreover, the original image is unnecessary for acquiring the watermark information. In the reconstruction procedure, only two bytes side information was required for digital image codec. The file size of watermarked JPEG compressed image approximates one without watermarking.
A tailored intervention to support pharmacy-based counseling for smoking cessation.

INTRODUCTION Pharmacists are uniquely positioned within the community to provide smoking cessation counseling to their patients. However, pharmacists experience significant barriers to providing counseling, including limited time, reimbursement, and training in counseling techniques. We tested a computer-driven software system, "Exper_Quit" (EQ), that provided individually tailored interventions to patients who smoke and matching tailored reports for pharmacists to help guide cessation counseling. METHODS A two-phase design was used to recruit an observation-only group (OBS; n = 100), followed by participants (n = 200) randomly assigned to receive either EQ-assisted pharmacist counseling or EQ plus 8 weeks of nicotine transdermal patch (EQ+). Both treatment groups were scheduled to receive two follow-up counseling calls from pharmacists. RESULTS Most participants in the EQ and EQ+ groups reported receiving counseling from a pharmacist, including follow-up calls, while none of the OBS participants reported speaking with the pharmacist about cessation. At 6 months, fewer OBS participants reported a quit attempt (42%) compared with EQ (76%) or EQ+ (65%) participants (p < .02). At 6 months, 7-day point-prevalence abstinence was 28% and 15% among the EQ+ and EQ groups, respectively, compared with 8% among OBS participants (p < .01), and EQ+ participants were twice as likely to be quit than were EQ participants (p < .01). DISCUSSION A tailored software system can facilitate the delivery of smoking cessation counseling to pharmacy patients. Results suggest that EQ was successful in increasing (a) the delivery of cessation counseling, (b) quit attempts, and (c) quit rates. Pharmacists can play an important role in the effective delivery of smoking cessation counseling.

Characterization of a Begomovirus-Betasatellite Complex, Producing Defective Molecules in Spinach (Spinacia oleracea L.), a New Host for Begomovirus and Betasatellite Complex in Pakistan

Spinach is a vegetable crop which is widely grown over a large area especially in Punjab province of Pakistan. Leaf curling and enations on spinach plant collected shown to be associated with the begomovirus Pedilanthus leaf curl virus (PeLCV) and Shahdadpur strain of Cotton leaf curl Multan betasatellite (CLCuMBSha). Defective molecules of half and quarter size derived from monopartite begomoviruses are usually generated by the deletion of virion-sense sequences. Characterization of defective molecules of PeLCV from spinach revealed that the molecules of half the size are derived from the deletion of complementary-sense genes while quarter size molecule appears to have evolved by further deletion. This is the first report of the begomovirus-betasatellite complex on spinach and unusual defective molecules derived from deletion of complementary-sense genes in Pakistan.

Evaluation of hardness , wear , corrosion resistance and magnetic properties of Austenitic Stainless Steel 316 LVM by means short high temperature gas nitriding

High temperature gas nitriding (HTGN) for austenitic stainless steel 316LVM is successfully done. Specimens are treated at temperature 1323, 1373 and 1573 K for 15 minutes holding time at 0.3 atm nitrogen gas pressures. As received and treated specimens were evaluated by means vickers micro hardness test, metallographic examination, abrasive wear test, corrosion test and vibrating sample magnetometer test. Hardness, wear resistance and grain size increase with temperature. However, the corrosion resistance at ringer solution decreases with temperature. HTGN treatments at 1323 K for 15 minute holding time are able to improve the hardness, wear resistance, corrosion resistance and increase the non-magnetic stability of 316LVM.
Vehicle Detection Using Local Size-Specific Classifiers

SUMMARY As the number of surveillance cameras keeps increasing, the demand for automated tra ﬃ c-monitoring systems is growing. In this paper, we propose a practical vehicle detection method for such systems. In the last decade, vehicle detection mainly has been performed by employing an image scan strategy based on sliding windows whereby a pre-trained appearance model is applied to all image areas. In this approach, because the appearance models are built from vehicle sample images, the normalization of the scales and aspect ratios of samples can signiﬁcantly inﬂuence the performance of vehicle detection. Thus, to successfully apply sliding window schemes to detection, it is crucial to select the normalization sizes very carefully in a wise manner. To address this, we present a novel vehicle detection technique. In contrast to conventional methods that determine the normalization sizes without considering given scene conditions, our technique ﬁrst learns local region-speciﬁc size models based on scene-contextual clues, and then utilizes the obtained size models to normalize samples to construct more elaborate appearance models, namely local size-speciﬁc classiﬁers (LSCs). LSCs can provide advantages in terms of both accuracy and operational speed because they ignore unnecessary information on vehicles that are observable in faraway areas from each sliding window position. We conduct experiments on real highway tra ﬃ c videos, and demonstrate that the proposed method achieves a 16% increased detection accuracy with at least 3 times faster operational speed compared with the state-of-the-art technique.
Evaluation of a voltage divider based on quantized Hall resistance arrays

A one-chip quantized voltage divider device based on integrated quantized Hall resistance (QHR) technology has been developed. A QHR voltage divider device that consists of a series of thirty-two quantized Hall bars has been fabricated. The dependence of the Hall resistance RH on the magnetic flux density showed that the device will function as a voltage divider. From the preliminary test of the 1:1 voltage ratio evaluation, the deviation from the nominal voltage ratio of 1:1 was estimated to be less than ± 10 × 10-6.
Detecting Driver’s Smartphone Usage via Nonintrusively Sensing Driving Dynamics

In this paper, we address a critical task of dynamically detecting the simultaneous behavior of driving and texting using smartphone as the sensor. We propose, design, and implement TEXIVE which achieves the goal of detecting texting operations during driving utilizing irregularities and rich micro-movements of users. Without relying on any external infrastructures and additional devices, and no need to bring any modification to vehicles, TEXIVE is able to successfully detect dangerous operations with good sensitivity, specificity, and accuracy by leveraging the inertial sensors integrated in regular smartphones. To validate our approach, we conduct extensive experiments involving in a number of volunteers on various of vehicles and smartphones. Our evaluation results show that TEXIVE has a classification accuracy of 87.18%, and precision of 96.67%.
Distribution and changing density of gamma‐delta T cells in murine skin during the induced hair cycle

Summary Gamma‐delta T cells (gdTC) are recognized as the predominant intraepidermal T‐cell population in murine skin, although their physiological functions are still unclear. Little is known of the exact distribution of gdTC in the other epithelial skin compartments of normal mice. Using selective gdTC‐receptor antibodies in immunohistology (alkaline phosphatase technique), the distribution and density of gdTC was analysed morphometrically in cryostat sections of full‐thickness back skin of normal, adolescent C57 BL‐6 mice in all the different stages of the depilation‐induced hair cycle. We found that, during the entire hair cycle, V gamma 3‐TCR‐bearing lymphocytes are restricted to the epidermis, and to the epithelial hair bulb in, and distal to, the bulge area. No gdTC were seen in the sebaceous glands. During early anagen development, the number of pan‐gdTC receptor‐positive cells increased significantly (P<0·005) in the interfollicular epidermis and the supainfundibular portion of the hair bulb, whereas the number decreased in the infrainfundibular region (P≤0.005). As gdTC are thought to migrate into the skin only during embryogenesis, this finding suggests hair cycle‐dependent, differential intraepithelial proliferation of gdTC in murine skin. We advocate employing only skin of defined hair cycle stages in immunological studies on murine skin, and discuss the value of the C57 BL‐6 model for assessing the functions of gdTC in skin and hair biology.
