Series ASSESSING MACROECONOMIC UNCERTAINTIES FOR AN EMERGING ECONOMY

This study constructs the macroeconomic uncertainty indices for an emerging economy, India, and considers other macroeconomic uncertainty indices to evaluate their relative effectiveness in terms of tracing the business cycles and finding out the transmission channels consistent with theory. The study estimates a series of VAR models using quarterly data to identify different uncertainty channels of aggregate demand and supply. The derived measures of uncertainty are higher around recessions and other structural changes like demonetization and GST implementation in India. Further, the empirical results show that the effects of uncertainty shocks to different domestic variables are consistent with the supply side of the real-option channel, the demand side of the investment channel, and the precautionary channel. Finally, to understand the effects of international spillover, this study measured the impact of US uncertainty on domestic variables, and the results suggest that US uncertainty has much more impact than domestic uncertainty, suggesting a significant international spillover effect of uncertainty in the Indian economy. These findings provide a holistic examination of how uncertainty affects macroeconomic activity from an emerging economy perspective. The results also suggest that the news-based economic policy uncertainty index, which is widely used in developed countries has not properly captured the state of economic uncertainty in India.
On Generalized Delannoy Numbers

The Delannoy numbers and the figurate numbers for n-dimensional cross polytopes are doubly-recursive sequences that satisfy the same recursion, and indeed have similar formulae, differing by one parameter. Further varying that parameter, we discover an infinite collection of doubly recursive sequences that satisfy the same recursion. These sequences enumerate certain types of lattice paths using the steps (1, 0), (0, 1), and (1, 1) and certain types of words on three letters. We use these combinatorial interpretations to prove relationships among the sequences.
Learning an Overlap-based Observation Model for 3D LiDAR Localization

Localization is a crucial capability for mobile robots and autonomous cars. In this paper, we address learning an observation model for Monte-Carlo localization using 3D LiDAR data. We propose a novel, neural network-based observation model that computes the expected overlap of two 3D LiDAR scans. The model predicts the overlap and yaw angle offset between the current sensor reading and virtual frames generated from a pre-built map. We integrate this observation model into a Monte-Carlo localization framework and tested it on urban datasets collected with a car in different seasons. The experiments presented in this paper illustrate that our method can reliably localize a vehicle in typical urban environments. We furthermore provide comparisons to a beam-endpoint and a histogram-based method indicating a superior global localization performance of our method with fewer particles.
Improved DFT – Based Channel Estimation Techniques for OFDM Signal

(OFDM) modulation is one of the most promising techniques used in wireless transmission systems. Performance of OFDM system in practice depends on channel estimation. Pilot tones are usually inserted within OFDM symbol for channel estimation. One of the most important methods for channel estimation is 'DFT-based channel estimation'. So it is considered in the present work. And two 'improved DFT-based channel estimation methods' are proposed and tested when operating over channels having different fading environments. The results of simulation tests show that better performance is achieved when compared to the system that uses conventional DFT-based channel estimation method. The proposed systems can work even without any prior knowledge about channel parameters.
Power-Management Techniques for OMAP35x Applications Processors

Advanced designs in OMAP3 application processors address the need for low power without sacrificing performance. Active power management adjusts a component’s operating frequency or voltage requirements to only those levels necessary. Static power management involves keeping an idle system in a power-efficient state until further processing is required. Plus, Texas Instruments (TI) has developed a number of external voltage regulators that lower the cost of implementing these powersaving features and reduce design time. In this white paper, we’ll review the concepts behind these various power-saving techniques, quantify the kinds of power savings that you can achieve with each, and discuss external power-management devices and power ICs that help multimedia processors reap the full benefits of these techniques.

Flying Not Flapping: A Strategic Framework for E-Learning and Pedagogical Innovation in Higher Education Institutions

E-learning is in a rather extraordinary position. It was born as a ‘tool’ and now finds itself in the guise of a somewhat wobbly arrow of change. In practice, changing the way thousands of teachers teach, learners learn, innovation is promoted and sustainable change in traditional institutions is achieved across hundreds of different disciplines is a demanding endeavour that will not be achieved by learning technologies alone. It involves art, craft and science as well as technology. This paper attempts to show how it might be possible to capture and model complex strategic processes that will help move the potential of e-learning in universities to a new stage of development. It offers the example of a four-quadrant model created as a framework for an e-learning strategy. DOI: 10.1080/09687760500376439
Management Accounting Systems Adoption Decisions: Evidence and Performance Implications from Early‐Stage/Startup Companies

Adopting management accounting systems are important events in the life of young and growing companies. Using a sample of 78 startup companies, we document cross‐sectional differences in the adoption of operating budgets as well as seven other management accounting systems. We find that our proxies for agency costs, perceived benefits and costs, company scale, and top management style explain cross‐sectional differences in the time‐to‐adoption of budgets. In particular, the presence of venture capital, CEO experience, presence of a financial manager, number of employees, and the CEO beliefs about management planning systems are associated with this adoption decision. We further investigate the effect of hiring a financial manager as an endogenous variable. In the first stage of a two‐stage model, we find that CEO experience, the presence of venture capital funds, CEO beliefs about management accounting systems, and number of employees are associated with crosssectional variation in this hiring decision.

Vírus da encefalite São Luis: primeiro isolamento de humano no Estado de São Paulo, Brasil

This paper reports the isolation of St. Louis encephalitis virus (SLEV) from a febrile human case suspected to be dengue, in Sao Pedro, Sao Paulo State. A MAC-ELISA done on the patient's acute and convalescent sera was inconclusive and hemagglutination inhibition test detected IgG antibody for flaviviruses. An indirect immunofluorescent assay done on the C6/36 cell culture inoculated with the acute serum was positive for flaviviruses but negative when tested with dengue monoclonal antibodies. RNA extracted from the infected cell culture supernatant was amplified by RT-PCR in the presence of NS5 universal flavivirus primers and directly sequenced. Results of BLAST search indicated that this sequence shares 93% nucleotide similarity with the sequence of SLEV (strain-MSI.7), confirmed by RT-PCR performed with SLEV specific primers. Since SLEV was identified as the cause of human disease, it is necessary to improve surveillance in order to achieve early detection of this agent in the state of Sao Paulo and in Brazil. This finding is also an alert to health professionals about the need for more complete clinical and epidemiological investigations of febrile illnesses as in the reported case. SLEV infections can be unrecognized or confused with other ones caused by an arbovirus, such as dengue.
Comparison of outcomes in intrauterine insemination, in vitro fertilisation and intracytoplasmic sperm injection in men with and without varicocele

Objectives: To investigate the differences in clinical pregnancy, miscarriage, and live birth rates when male partners were diagnosed with a varicocele and to compare these outcomes to those without and study the outcomes based on the grade of varicocele. Methods: The retrospective study was based on a cohort of consecutive infertile couples undergoing assisted reproductive technology (ART) at the Reproductive Center of Shandong Provincial Hospital affiliated to the Shandong University during the period between January 2017 and December 2018. A total of 4203 couples comprised of men with and without varicocele undergoing the first ART cycle (1501 intrauterine inseminations (IUI), 1623 in vitro fertilisations (IVF) and 1079 intracytoplasmic sperm injections (ICSI)) were included. Semen parameters and ART outcomes were determined. Results: ICSI (26.5%) originated from men with a significant lower level in sperm concentration and motility but with a strict normal morphology had a higher prevalence of varicocele than men undergoing IUI (20.7%) and IVF (18.1%). In IUI, the odds ratios (ORs) for pregnancy and live birth were significantly lower for couples in men diagnosed with grades 1 or 2 varicocele as compared to those for men with grade 3 varicocele. In IVF, ORs for live birth where men were diagnosed with grades 1 or 2 varicocele were also lower than those for men with grade 3,whereas a higher miscarriage rate was found when men had grades 1 or 2 varicocele than when men had grade 3. However, for ICSI, no significant outcomes were found in grades 1, 2 or 3 varicocele versus the no varicocele group. Conclusions: The increasing grade of varicocele was negatively associated with sperm parameters and can alter the outcome of further IUI/IVF.

This multiple case study creates and identifies some key performance indicators, accounting information systems and control tools. The descriptive analysis evidences that the cruise event management processes are separated.
VISIBLE GRAPHIC QR CODE WITH EMBEDDED INVISIBLE QR CODE TO ENHANCE ANTI-COUNTERFEITING FEATURES

- QR code is a popular interface to deliver information between reality andvirtual world. It also plays an important role in marketing advertisement and transactional payment.However, it is sometimes misappropriated and forged by fraudulent users. Therefore, the security of QR code still needs to be strengthened. On the other hand, QR code is not recognizable by human vision because it consists of black and white modules. By the techniques of digital halftoning and data hiding, a graphic QR code embedded with an invisible QR code is developed to enhance the security features. Its explicit QR code can be normally interpreted by a QR code reader, and the message of the implicit QR code can be decoded by inputting the correct key. The research reaches the goal of graphic QR code to be both aesthetically pleasing and strengthening the anti-counterfeiting features.

Objective To determine the association of the human 8-hydroxyguanine glycosylase(hOGG1)Ser326Cys polymorphism and esophageal cancer risk in Huaian.Methods hOGG1 genotyping was performed by di-allele specific-amplification with artificially modified primer(diASA-AMP)analysis of genomic DNA isolated from 106 pairs of esophageal cancer cases and non-cancer controls individually matched by residence,sex and age.The association of the genetic polymorphisms and cancer risk was evaluated by a multivariate analysis.Results The frequency of Ser/Ser,Ser/Cys,and Cys/Cys genotypes in the control subjects were 19.8%,47.2% and 33.0% respectively,and there was no significant difference in the distribution of the hOGG1 Ser326Cys polymorphism between this studied group and other reported Chinese groups.The hOGG1 genotypes of 10 random samples were verified with DNA sequencing.No significant difference was observed in the frequency of hOGG1 genotypes between controls and cases(χ~2=1.439;P=0.696). No significantly increased risk for esophageal cancer was observed for those carrying 326Cys allele with Logistic regression analysis(OR=1.385;95%CI=0.678～2.823). And also no statistically significant interactions between hOGG1 Ser326Cys polymorphism and smoking or other possible confounding factors were observed for esophageal cancer risk.Conclusion hOGG1 Ser326Cys polymorphism is unlikely to be associated with the susceptibility to esophageal cancer.The polymorphisms play no role in the risk of smoking for esophageal cancer.The diASA-AMP method in an available technique for single nucleotide polymorphism(SNP)rapid determination with its ideal specificity.
Correlates of rarity in UK bumblebee (Bombus spp.) populations

Correlates of rarity in UK bumblebee (Bombus spp.) populations Sarah Elizabeth Rustage The decline of bumblebee (Bombus spp.) populations in the UK and worldwide has been well reported. It has been generally assumed that such declines result in the genetic impoverishment of some species, potentially leading to reduced fitness and increased extinction risk. This study tested the fundamental assumption linking population fragmentation with fitness, in a model system of two Bombus species native to the UK. Bombus monticola has declined significantly in range across the UK in recent years and occupies fragmented upland areas, while Bombus pratorum has remained abundant and widespread over many habitat types. The effects of genetic diversity on fitness have been addressed in wild Bombus species, but this is the first study to explicitly compare data from species of differing levels of population connectivity and hence test the assumptions of traditional population genetic theory. As genetic diversity has often been linked with immunocompetence, aspects of the innate immune response were quantified, together with parasite load. These empirical measures of fitness showed lower than expected variability between the two study species, and no evidence was found to support the theory of lower fitness in fragmented populations. However, the considerable variability between sample sites in both species for all parameters measured raised interesting questions as to the underlying evolutionary processes; it is postulated that B. monticola populations may maintain a higher than expected Ne, despite their fragmented distribution. This study also provided methodological developments. An alternative method for the quantification of wing wear as a proxy for age was proposed, which could be easily applied to other Bombus species and possibly adapted for use in other flying insects. In addition possible sources of error in AFLP analysis were highlighted which have not been adequately discussed in the current literature, namely the effects of sample storage. Given the utility of AFLPs for non-model species, this is an important avenue for future research, and would be applicable to studies in other systems. Overall, the data presented here emphasise the challenges of studying fitness in wild populations, and underline the requirement for research into the fundamental principles underlying many assumptions made by conservation genetic theory.
R2 IM- Robust and Resilient Intersection Management of Connected Autonomous Vehicles

Intersection management of Connected Autonomous Vehicles (CAVs) has the potential to significantly improve safety and mobility. While numerous intersection management designs have been proposed in the past few decades, most of them assume that the CAVs will precisely follow the directions of the Intersection Manager (IM) and prove the safety and demonstrate the efficiency based on this assumption. In real life, however, a CAV that is crossing the intersection may break down, accelerate out-of-control or lie about its information (e.g. intended outgoing lane) and cause an accident. In this paper, we first define a fault model called “rogue vehicle”, which is essentially a CAV that either is dishonest or does not follow the IM’s directions and then, propose a novel management algorithm $(R^{2}IM)$ that will ensure safe operation, even if a CAV becomes “rogue” at any point in time. We prove that there can be no accidents inside the intersection, as long as there is no more than one “rogue vehicle” at a time. We demonstrate the safety of $R^{2}IM$ by performing experiments on 1/10 scale model CAVs and in simulation. We also show that our approach can recover after the rogue vehicle leaves/is removed.

PPG signal preprocessing and comparison study with learning-based model for stress detection

PPG signals are widely used to measure and provide personalized health information in wearable devices. However, PPG signals are often corrupted by different artifacts, and the corrupted signals lead to a deterioration in the performance of downstream studies. To improve the quality of PPG signals, we propose a simple but effective two-step noise reduction algorithm. First, the algorithm uses Discrete Fourier Transform to suppress noise components in terms of frequency. Then, it removes remaining noises in terms of time. Consequently, we confirm that the proposed PPG noise reduction method increases the PPG peak matching ratio and eventually improves the stress detection performance of learning-based models, such as random forest, support vector machines, and gradient boosting. As the demand for wearable devices increases and the growth of the healthcare industry continues, we expect that more accurate health management would be available through the proposed PPG noise reduction method.
