Venture Capital and the Diffusion of Knowledge

I estimate the impact of venture capital (VC) on knowledge diffusion by comparing patent citations before and after companies secure VC. I find that a patent's citations increase following VC financing, particularly those made by other companies also financed by the same VC investor. Instrumental variables estimates exploiting variation in the assets of pension funds that allocate capital to VC suggest a causal interpretation of the findings. I argue that by certifying commercial value, VC facilitates knowledge diffusion and thus generates an externality on innovation. The findings help explain why VC is more effective in stimulating innovation than corporate R&D.
Attempt to Raise the Predictive Accuracy in Binary Logistic Regression Analysis

Objective: It is necessary to improve the predictive accuracy of binary logistic regression analysis. This study aimed to clarify whether binary logistic regression analysis using Functional Independence Measure (FIM) gain (a 0/1 binary value) as a dependent variable increases the predictive accuracy when FIM at admission (FIMa) is categorized or when multiple predictive formulae are created. Methods: The study population consisted of 2,542 stroke patients admitted to convalescent rehabilitation wards in Japan. We compared the predictive accuracy of FIM gain between a formula using FIMa as quantitative data (A), a formula that categorized FIMa into 4 groups (B), and two predictive formulae (C). Result: The predictive accuracy of these formulae, in descending order, was found to be C (76.3%), B (76.0%), and A (68. 4%). Conclusion: Even more than using FIMa as quantitative data, the predictive accuracy of FIM gain was heightened by either categorizing FIMa into 4 groups or by creating two predictive formulae.
RoadPlot-DATMO: Moving object tracking and track fusion system using multiple sensors

This paper introduces the RoadPlot-DATMO, tracking objects around the vehicle using multiple sensors such as radars, 2D LiDARs, and a 3D LiDAR. It consists of the xytracker, the xyztracker, and the fusion; the xytracker tracks moving objects with multiple 2D LiDARs, the xyztracker perceives object information in detail using a 3D LiDAR, and the fusion merges tracks from multiple trackers. It is able to detect and to track moving objects around the vehicle correctly and continuously without blind area in realtime. Also, this was tested with driverless overtaking on a highway using the autonomous vehicle, the CoPilot of the ETRI.
Hurricane Isaac: A Longitudinal Analysis of Storm Characteristics and Power Outage Risk

In August 2012, Hurricane Isaac, a Category 1 hurricane at landfall, caused extensive power outages in Louisiana. The storm brought high winds, storm surge, and flooding to Louisiana, and power outages were widespread and prolonged. Hourly power outage data for the state of Louisiana were collected during the storm and analyzed. This analysis included correlation of hourly power outage figures by zip code with storm conditions including wind, rainfall, and storm surge using a nonparametric ensemble data mining approach. Results were analyzed to understand how correlation of power outages with storm conditions differed geographically within the state. This analysis provided insight on how rainfall and storm surge, along with wind, contribute to power outages in hurricanes. By conducting a longitudinal study of outages at the zip code level, we were able to gain insight into the causal drivers of power outages during hurricanes. Our analysis showed that the statistical importance of storm characteristic covariates to power outages varies geographically. For Hurricane Isaac, wind speed, precipitation, and previous outages generally had high importance, whereas storm surge had lower importance, even in zip codes that experienced significant surge. The results of this analysis can inform the development of power outage forecasting models, which often focus strictly on wind‐related covariates. Our study of Hurricane Isaac indicates that inclusion of other covariates, particularly precipitation, may improve model accuracy and robustness across a range of storm conditions and geography.
Supernatural believers attribute more intentions to random movement than skeptics: An fMRI study

A host of research has attempted to explain why some believe in the supernatural and some do not. One suggested explanation for commonly held supernatural beliefs is that they are a by-product of theory of mind (ToM) processing. However, this does not explain why skeptics with intact ToM processes do not believe. We employed fMRI to investigate activation differences in ToM-related brain circuitries between supernatural believers (N = 12) and skeptics (N = 11) while they watched 2D animations of geometric objects moving intentionally or randomly and rated the intentionality of the animations. The ToM-related circuitries in the medial prefrontal cortex (mPFC) were localized by contrasting intention-rating-related and control-rating-related brain activation. Compared with the skeptics, the supernatural believers rated the random movements as more intentional and had stronger activation of the ToM-related circuitries during the animation with random movement. The strength of the ToM-related activation covaried with the intentionality ratings. These findings provide evidence that differences in ToM-related activations are associated with supernatural believers’ tendency to interpret random phenomena in mental terms. Thus, differences in ToM processing may contribute to differences between believing and unbelieving.
High-Temperature Resistance Fiber Bragg Grating Temperature Sensor Fabrication

Fiber Bragg grating (FBG) temperature sensor and sensor arrays were applied widespread particularly in harsh environments. Although FBGs are often referring to permanent refractive index modulation in the fiber core, exposure to high-temperature environments usually results in the bleach of the refractive index modulation. The maximum temperature reported for the conventional FBG temperature sensor is around 600 degC due to its weak bonds of germanium and oxygen. In this paper, we report design and development of a novel high-temperature resistance FBG temperature sensor, based on the hydrogen-loaded germanium-doped FBG. The refractive index modulation in the FBG is induced by the molecular water. The results of our experiments have shown that the stability of the device is substantially increased at high temperature range. Due to the high bonds energy of hydroxyl and the low diffusivity of the molecular water, the thermal testing results of this temperature sensor show the thermal stability of hydrogen-loaded FBG can be increased by using annealing treatment; moreover, the highest erasing temperature for the device could reach to 1100 degC or more. The reflectivity of this new FBG depends on the concentration of Si-OH and indirectly related to the reflectivity of hydrogen-loaded FBG. Furthermore, the experimental results have provided a better understanding of the formation of the hydrogen-loaded FBGs and the chemical transfers at elevated temperatures in the fiber core
The gene expression signature of genomic instability in breast cancer is an independent predictor of clinical outcome

Recently, expression profiling of breast carcinomas has revealed gene signatures that predict clinical outcome, and discerned prognostically relevant breast cancer subtypes. Measurement of the degree of genomic instability provides a very similar stratification of prognostic groups. We therefore hypothesized that these features are linked. We used gene expression profiling of 48 breast cancer specimens that profoundly differed in their degree of genomic instability and identified a set of 12 genes that defines the 2 groups. The biological and prognostic significance of this gene set was established through survival prediction in published datasets from patients with breast cancer. Of note, the gene expression signatures that define specific prognostic subtypes in other breast cancer datasets, such as luminal A and B, basal, normal‐like, and ERBB2+, and prognostic signatures including MammaPrint® and Oncotype DX, predicted genomic instability in our samples. This remarkable congruence suggests a biological interdependence of poor‐prognosis gene signatures, breast cancer subtypes, genomic instability, and clinical outcome. © 2008 Wiley‐Liss, Inc.
Preoperative evaluation of intracranial aneurysms: usefulness of intraarterial 3D CT angiography and conventional angiography with a combined unit--initial experience.

PURPOSE To assess the usefulness of intraarterial computed tomographic (CT) angiography in conjunction with digital subtraction angiography (DSA) by using a combined CT and angiographic unit in the preoperative evaluation of intracranial aneurysms. MATERIALS AND METHODS Prospectively, 22 patients with or without subarachnoid hemorrhage underwent CT angiography in conjunction with DSA. Two radiologists independently evaluated DSA and CT angiographic images. Referring neurosurgeons were questioned as to how the additional information provided by CT angiography changed patient treatment. RESULTS Intraarterial CT angiography was superior to DSA for use in aneurysm detection in three (12%) of 26 aneurysms and for delineation of aneurysm shape, neck, and location in more than half. In 14 (64%) of 22 patients, CT angiography demonstrated 18 additional findings: a very small aneurysm (n = 2), aneurysm shape and neck (n = 6), relationship of the aneurysm to adjacent arteries or bone structure (n = 8), and branches deriving from the aneurysm (n = 2). In four (27%) of 15 patients who underwent surgery or embolization, additional information obtained at CT angiography affected the treatment. CT angiography failed to clearly demonstrate an aneurysm adjacent to bone structures and small perforators, which were derived from the parent artery. CONCLUSION Intraarterial CT angiography is useful for preoperative evaluation of intracranial aneurysms as a supplement to DSA.
Clinical microneedle injection of methyl nicotinate: stratum corneum penetration

Background/purpose: In recent years, microneedles were proposed as a method to painlessly deliver drugs past the stratum corneum. Microneedles have been fabricated in several designs, but limited studies have tested microneedle injections in humans. In this work, we compare microneedle injections with topical application (TA) to investigate if microneedles enhance in vivo drug delivery past the stratum corneum.
The Role of Corporate, Legal and Macroeconomic Balance Sheet Indicators in Crisis Detection and Prevention

This study tests the recent balance sheet explanations of external crises in emerging market countries and the role of standards in these crises. Using several unique data sets, it finds that corporate sector balance sheets have a very significant impact on both the likelihood and depth of external crises. The indicators supplement, rather than substitute for traditional macroeconomic variables with standards playing potentially an important role. The results have implications for strategies to limit external vulnerability: they suggest that policymakers need to promote sound private sector financial structures, support sound shareholder rights, in addition to employing prudent macroeconomic policies to reduce exposure to crises. In sample predictions point to potentially large improvements in the predictive power of models that include these indicators.
Evidence on the Empirical Relationship between Forecast Accuracy and Recommendation Profitability

This paper analyzes empirically the relation between financial analysts' forecast accuracy and their recommendation profitability and shows that contrary to intuition the group of most successful recommendations is not associated with the highest accuracy on average. The finding that best performing recommendations are not the most accurate ones is even stronger under conditions of asymmetric information and weakly correlated recommendations. Our results emphasize the importance of the extent to which forecasts are correlated, and contributes to the understanding of the lack of a clear-cut relation between accuracy and recommendation profitability.
Quantification of Anthocyanins in Elderberry and Chokeberry Dietary Supplements

Elderberry and chokeberry food supplements may be ‘functional food’ in patients with metabolic syndrome or influenza but, for this, adequate amounts of co‐active ingredients must be consumed in the daily dose. This study aimed to quantify the anthocyanin content in three elderberry and six chokeberry products to assess their usefulness as functional food. Analyses were carried out using an established HPLC procedure. The minimum anthocyanin doses for the treatment of metabolic syndrome disorders were estimated as 110 mg per day and 3.5 g per day for influenza. Three products were inappropriate for clinical use. The lowest liquid supplies were achieved with a proprietary elderberry concentrate (11 mL) and a proprietary chokeberry mother juice (100 mL). Clinical studies are now required to prove the effectiveness and adapt the doses according to the clinical symptoms. Copyright © 2015 John Wiley & Sons, Ltd.
R&D Strategy, Metropolitan Externalities and Productivity

This paper studies the influence of metropolitan externalities on productivity for different types of long run R&D engagement based on information from the Community Innovation Survey. We apply a dynamic general method of moments model to a panel of manufacturing and service firms with different locations in Sweden, classified as a metropolitan region, the largest metropolitan region, a metropolitan city, the largest metropolitan city and a non-metropolitan area. This analysis generates three distinct results. First, the productivity premium associated with persistent R&D is close to 8 percent in non-metro locations and about 14 percent in the largest city. Second, a firm without any R&D engagement does not benefit at all from the external milieu in metro areas. Third, no productivity premium is associated with occasional R&D effort regardless of the firm’s location.

Simulation Experiments in Choice Simplification: The Effects of Task and Context on Forecasting Performance

Experimental and protocol-based research has demonstrated convincingly that consumers frequently use simplification heuristics prior to making choices. Consequently, quantitative choice models incorporating simplification strategies recently have received much research attention. Given the additional computational cost and complexity involved in estimating these models, the authors investigate how robustly the standard logit model accommodates choice simplification processes. The results show that when consumers screen brands using an elimination-by-aspects strategy, logit forecasts choices reasonably well, but the parameter estimates are severely biased. However, when consumers screen through brands previously purchased, augmented by brands promoted, logit both forecasts poorly and produces biased parameter estimates, even when dedicated screening variables are included in the logit utility function. The predictive validity of logit improves somewhat when the universal set size is small and when purchase event feedback is less important.

On the Downlink Throughput Capacity of Hybrid Wireless Networks With MIMO

In this paper, the downlink throughput capacity of hybrid wireless networks is mainly studied. Multiple-input multiple-output (MIMO) technology is assumed to be equipped on the base station and nodes to improve communication performance and increase the whole network throughput. A wireless network is also set up, with a wired network of base stations to support the remote communication of wireless nodes. In order to overcome the inter-cell interference, the frequency reuse technology is adopted. Under the favorable propagation condition, MIMO significantly mitigates the effect of fading between the node antenna and the base station antenna. We first analyze the downlink outage throughput capacity in slow fading scenarios and get the close-form outage capacity. Then, we analyze the ergodic throughput capacity over fast fading channel and get the ergodic capacity in both low SNR and high SNR scenarios. Finally, the availability of MIMO technology is proved by computer simulation.
Development of a collagen-binding activity assay as a screening test for type II von Willebrand disease in dogs.

OBJECTIVE To develop an assay to measure canine von Willebrand factor (vWF):collagen-binding activity (CBA) to screen for type 2 von Willebrand disease (vWD) in dogs. SAMPLE POPULATION 293 plasma samples submitted for analysis of canine vWF antigen (vWF:Ag) and 12 control plasma samples from dogs with inherited type 2 or 3 vWD. PROCEDURE Bovine collagens were evaluated for suitability as binding substrate for vWF. Assay sensitivity to depletion, proteolytic degradation, or a genetic deficiency of high-molecular-weight vWF were determined. Amounts of vWF:Ag and vWF:CBA were measured. The ratio of vWF:Ag to vWF:CBA was used to discriminate between type 1 and type 2 vWD. RESULTS An assay for canine vWF activity was developed by use of mixed collagen (types I and III). When vWF:Ag was used to subtype vWD, 48% of the dogs were classified as clinically normal, 9% as indeterminate, and 43% as type 1 vWD. Inclusion of vWF activity resulted in reclassification of 5% of those identified as type 1 to type 2 vWD. However, vWF:CBA of the reclassified dogs was not persistently abnormal, a finding compatible with acquired type 2 vWD. Some Doberman Pinschers had lower antigen-to-activity ratios than other breeds with type 1 vWD, suggesting that Doberman Pinschers have more functional circulating vWF. CONCLUSIONS AND CLINICAL RELEVANCE Analysis of canine vWF activity should be included among the vWF-specific assays used to confirm type 2 vWD. The prevalence of inherited forms of type 2 vWD in screened dogs is lower than acquired forms that can result secondary to underlying disease.
Design of infinite horizon predictive LQ controller

A singlevariable controller is developed in the predictive control framework based upon minimization of the LQ criterion with infinite output and control horizons. The infinite version of the predictive cost function results in better stability properties of the controller and still enables to incorporate contraints into the control design. The constrained LQ controller (CLQ) consists of two parts: time-invariant nominal LQ controller and time-variant part given by Youla-Kucera parametrization of all stabilizing controllers that takes care of constraints.

Face Recognition Based on Local Directional Pattern Variance ( LDPv )

Face recognition is becoming very popular tools for a successful human commuter interaction system. It seems to be a good compromise between reliability and social acceptance and balances security and privacy well. In this paper, we have presented a new appearance-based feature descriptor, the local directional pattern Variance (LDPv), to represent facial components and analyzed its performance for face. A LDP feature is computed from the relative edge response values in all eight directions at each pixel position, and then, the LDPv descriptor of a facial image is generated from the integral projection of each LDP code weighted by its corresponding variance. The final face representation is then described by the concatenated histogram of LDPv of local regions that encodes both global and local texture information. The recognition performance with FERET datasets demonstrates the robustness of proposed LDPv descriptor for representing appearance of facial image over other existing state of the art approaches.
High resolution image reconstruction from digital video with global and non-global scene motion

This paper describes a technique for reconstructing a high resolution image from a sequence of low resolution frames. The input frames must contain some scene motion relative to the focal plane array so that some unique samples are provided with each frame. We consider global scene motion and a special case of non-global scene motion. The global motion algorithm is tested using actual flight data collected from an infrared imager mounted on an aircraft.
