Downlink eigenbeamformer with combining of eigenbeams

For W-CDMA several closed-loop Tx diversity concepts employing 4 antenna elements at the base station (BS) are currently discussed to be included in 3GPP release 5. Among these, the downlink eigenbeamformer effectively uses long-term as well as short-term channel properties. More specifically, it is based on an eigenanalysis of the long-term spatial covariance matrix at the mobile station (MS). The eigenvectors (vector of complex weighting factors for all antenna elements) with the largest eigenvalues (largest average signal power) are determined and fed back step by step to the BS. This process takes place on the same time scale as the MS physical movement. Accordingly, required operations in the MS for eigenanalysis as well as required long-term feedback bits for representation of eigenvectors are distributed over a very large number of transmission slots. As an extension of simple switching between eigenbeams a linear combination of several eigenbeams is considered. This combining is performed using constellation rotation and progressive refinement techniques applied to the eigenbeam space. Performance of combining methods is compared with an upper bound (beamforming based on perfect short-term knowledge of the downlink channel) and uplink based beamforming methods where only the long-term spatial covariance matrix is known at the BS. Although combining methods require more short-term feedback information then simple switching and thus are more sensitive to feedback delay and restricted feedback rate, they prove to be beneficial up to a vehicle speed of 40 km/h.
Hybrid reduced graph for SAR studies

The purpose of this work is the definition and evaluation of both atomic and local new hybrid indices. Inspired by the Refractotopological State Index for Atoms, the new atomic indices are theoretically supported by graph theory principles. The local indices, named Descriptor Centres (DCs), are obtained from the sum of the atomic values of the atoms in the selected group. Different classifiers were used for structure–activity relationship (SAR) studies, including multilayer perceptron (MLP), support vector machines (SVM) and meta-classifiers. Prediction with SVM and MLP was around 60%, but the best result was obtained with the meta-classifiers, bagging, decorate and others, with more than 92% accurate prediction. These new hybrid descriptors derived from the Refractotopological State Index for Atoms show a low mutual correlation coefficient. The same behaviour is found in the analogously defined Descriptors Centres. The best results are obtained with the inclusion of the distance between DCs with the use of meta-classifiers.
Tunnel junctions in GaN/AlN for optoelectronic applications

The authors propose a new device design using the polarization properties of the III-nitrides system that eliminates the need for high doping concentrations and has the further benefit of potentially eliminating problematic p-type contacts. P-type material in the nitrides is plagued by high contact resistance and high sheet resistance. These problems could be eliminated by contacting n-type material that acts as a current spreading layer and using a tunnel junction to transfer current to p-type material with minimal losses (Takeuchi et al., 2001)
Bed Bugs: Clinical Relevance and Control Options

SUMMARY Since the late 1990s, bed bugs of the species Cimex lectularius and Cimex hemipterus have undergone a worldwide resurgence. These bed bugs are blood-sucking insects that readily bite humans. Cutaneous reactions may occur and can start out as small macular lesions that can develop into distinctive wheals of around 5 cm in diameter, which are accompanied by intense itching. Occasionally, bullous eruptions may result. If bed bugs are numerous, the patient can present with widespread urticaria or eythematous rashes. Often, bites occur in lines along the limbs. Over 40 pathogens have been detected in bed bugs, but there is no definitive evidence that they transmit any disease-causing organisms to humans. Anemia may result when bed bugs are numerous, and their allergens can trigger asthmatic reactions. The misuse of chemicals and other technologies for controlling bed bugs has the potential to have a deleterious impact on human health, while the insect itself can be the cause of significant psychological trauma. The control of bed bugs is challenging and should encompass a multidisciplinary approach utilizing nonchemical means of control and the judicious use of insecticides. For accommodation providers, risk management procedures should be implemented to reduce the potential of bed bug infestations.
Towards an Understanding of Risk Management in Legacy Information Systems Modernisations

The modernisation of legacy information systems is a problematic and risky process that many organisations will undertake at some stage during their lifetime. When modernising a legacy information system a number of different approaches can be used, ranging from a simple ‘updating’ of the existing system to its wholesale replacement. Little appears to have been written about the problems and risks that relate specifically to these different legacy information system modernisation approaches. Understanding these risks would seem important for project managers when managing modernisation projects and also for decision makers when deciding which approach is most appropriate for a particular project. This paper outlines the initial stages of a research project that to seeks identify, understand and assess the risks involved in both the modernisation process itself and the ongoing use of the modernised system across these various types of legacy system modernisation.
The Characters of the Eco-Industrial Park in EU and US and the Inspiration for the Wuhan Metropolitan Zone

Since the beginning of the 21st century, the eco-industrial park has become the important carrier for the development of circular economy in the US and the EU countries. It is also the new direction and trend for the development of the industrial park. This paper discusses the main characters of the eco-industrial park through the analysis of the eco-industrial park in the US and EU. The Wuhan metropolitan zone is now in the process of its attempt for the construction of resource-conservation and environment-protection society under the guidance of the Chinese Central Government. Based on the detailed discussion on the development status and main problems of the industrial parks in the Wuhan metropolitan zone, the author finally points out some practical suggestion for their future development.
Development of Rotating Type Transverse Flux Machine

This paper describes the design and development of rotating type transverse flux motors (TFM) excited by permanent magnets. In-plane phase construction and axial phase arrangement are compared each other and many variants of them are introduced by combining soft magnetic composite (SMC) core and laminated steel core. Magnetic field is analyzed by three-dimensional equivalent magnetic circuit network (EMCN) method with the help of two-dimensional finite element analysis. The experimental results of prototyped motor compared with the analysis ones, and show the possibility of the suggested motor as a direct drive application requiring relatively low speed and high torque.
More Than Meets the Eye: How Oculometric Behaviors Evolve Over the Course of Automated Deception Detection Interactions

Abstract Eye-tracking technology has exhibited promise for identifying deception in automated screening systems. Prior deception research using eye trackers has focused on the detection and interpretation of brief oculometric variations in response to stimuli (e.g., specific images or interview questions). However, more research is needed to understand how variations in oculometric behaviors evolve over the course of an interaction with a deception detection system. Using latent growth curve modeling, we tested hypotheses explaining how two oculometric behaviors—pupil dilation and eye-gaze fixation patterns—evolve over the course of a system interaction for three groups of participants: deceivers who see relevant stimuli (i.e., stimuli pertinent to their deception), deceivers who do not see relevant stimuli, and truth-tellers. The results indicate that the oculometric indicators of deceivers evolve differently over the course of an interaction, and that these trends are indicative of deception regardless of whether relevant stimuli are shown.
Dietary vitamin D supplementation attenuates immune responses of pigs challenged with rotavirus potentially through the retinoic acid-inducible gene I signalling pathway

In the present study, twenty-four Duroc × Landrance × Yorkshire (initial body weight (BW) of 21·82 (sem 2·06) kg) cross-bred pigs were used to determine whether dietary vitamin D supplementation could confer protection against viral infections through the retinoic acid-inducible gene I (RIG-I) signalling pathway in pigs. Experimental treatments were arranged in a 2 × 2 factorial manner with the main effects of immune challenge (control v. porcine rotavirus (PRV) challenge) and dietary concentrations of vitamin D (200 and 5000 IU; where 1 IU of vitamin D is defined as the biological activity of 0.025 mg of cholecalciferol). The pigs were fed a diet containing 200 or 5000 IU vitamin D in the first week of the study period. On day 8, the pigs were orally dosed with 4 ml of Dulbecco's modified Eagle's medium/Ham's F-12 medium containing PRV or essential medium (control). Serum samples were collected on day 8 (pre-challenge), and 6 d after the PRV challenge, the pigs were killed to evaluate intestinal morphology and tissue gene expression following the last blood collection. Pigs challenged with PRV had decreased BW gain (P< 0·01), feed intake (P< 0·01), villus height (P< 0·01), faecal consistency (P< 0·05), and serum 1,25-dihydroxyvitamin D concentration (P< 0·01) and increased (P< 0·01) serum IL-2, IL-6 and interferon (IFN)-β concentrations. Vitamin D supplementation mitigated these effects. The mRNA expression of RIG-I (P< 0·01), IFN-β promoter stimulator 1 (P< 0·01), IFN-β (P< 0·01) and interferon-stimulated gene 15 (ISG 15 ) (P< 0·01) was up-regulated by the PRV challenge and vitamin D supplementation in the intestine. In conclusion, vitamin D supplementation could activate the RIG-I signalling pathway and thus alleviate the negative effects caused by PRV challenge.
Tax Deferral and Mutual Fund Inflows - Evidence from a Quasi-Natural Experiment

We propose a new method to identify the impact of a change in the tax burden on mutual fund inflows, exploiting a switch from an accrual-based to a realization-based tax regime. We use quasi-experimental data from Italy where, starting from July 2011, the tax regime for domestic mutual funds was changed from an accruals basis to a realization basis, while the taxation of foreign funds remained on a realization basis. We find that the reform has had a positive effect on net inflows of Italian funds (the treated group) with respect to foreign funds (the control group). The effect is both economically and statistically significant. Moreover, we find no evidence that the increase in the demand for Italian funds came at the expense of foreign funds.
Simulation of future forest and land use/cover changes (2019–2039) using the cellular automata-Markov model

Abstract This study aimed to simulate and assess forest cover and land use/land cover (LULC) changes between 2019 and 2039 using the cellular automata-Markov model. The performance of the model was evaluated by comparing the 2019 simulation map with the 2019 supervised classified map, and it was found to be reliable, with a similarity rate of 85.43%. The LULC analysis and estimates were carried out for a total of six classes: coniferous, broad-leaf, mixed forest, settlement, water and agriculture. Between 1999 and 2019, the areas of total forest increased by 17.4%, settlement by 84.6% and water by 20.1%, whereas the agriculture area decreased by 33.2%. According to 2019‒2039 land use/cover simulation results, there were decreases of 2.4% in total forest area and 3.7% in residential and water surface areas, but a 6.9% decrease in the agriculture class. Tracking these changes will contribute to decision making and strategy development efforts of forest planners and managers.
Antibiotic exposure Increased patient age Prior hospitalization Severity of underlying illness Proton pump inhibitors and H 2 blocker use Abdominal operation Nasogastric tube Long duration of hospitalization Long-term care residency IBD Organ transplantation Chemotherapy Chronic kidney disease

Clostridium difficile infections are the leading cause of health care–associated infectious diarrhea, posing a significant risk for both medical and surgical patients. Because of the significant morbidity and mortality associated with C difficile infections, knowledge of the epidemiology of C difficile in combination with a high index of suspicion and susceptible patient populations (including surgical, postcolectomy, and inflammatory bowel disease patients) is warranted. C difficile infections present with a wide spectrum of disease, ranging from mild diarrhea to fulminant colitis or small bowel enteritis and recurrent C difficile infections. Early implementation of medical and operative treatment strategies for C difficile infections is imperative for optimal patient outcomes. National and international guidelines recommend early operative consultation and total abdominal colectomy with end ileostomy and preservation of rectum. Diverting loop ileostomy and colonic lavage followed by intravenous metronidazole and intracolonic vancomycin administered via the efferent limb of the ileostomy should be considered as an alternative to total colectomy in selected patients. New and emerging strategies for C difficile infection treatment include monoclonal antibodies, vaccines, probiotics, biotherapeutics, and new antibiotics. A successful C difficile prevention and eradication program requires a multidisciplinary approach that includes early disease recognition, implementation of guidelines for monitoring adherence to environmental control, judicious hand hygiene, evidence-based treatment and management strategies, and a focused antibiotic stewardship program. Surgeons are an important part of the clinical team in the management of C difficile infection prevention and treatment. (Surgery 2017;j:j-j.)
Statistical Parametric Analysis of Cerebral Blood Flow in Vascular Dementia with Small-Vessel Disease Using 99mTc-HMPAO SPECT

Background: Subcortical ischemic vascular dementia (SVD) caused by small-artery disease is a major cause of dementia. It still remains unclear, however, whether SVD may present with localized regional cerebral blood flow (rCBF) changes. We aimed to clarify the local rCBF changes associated with dementia in patients with early-stage SVD. Methods: The subjects consisted of 15 patients with early-stage SVD [Mini Mental State Examination (MMSE) score: 20 ± 3.5] without apparent brain atrophy (SVD group), 11 patients without dementia with white matter lesions (non-dementia-WML group) and 16 age-matched controls. All the subjects were right-handed and underwent brain perfusion single photon emission computed tomography (SPECT), magnetic resonance imaging and cognitive function testing. Statistical analysis of the differences in the SPECT rCBF was performed by SPM2. The degree of severity of the WMLs was evaluated based on the Scheltens rating scale. Results: The results of SPM analysis revealed that the rCBF in the SVD group was significantly decreased in the pulvinar nuclei of the thalamus of both sides as compared with that in the controls, and in the left pulvinar nucleus as compared with that in the non-dementia-WML group. On the other hand, SPM analysis revealed no significant reduction in rCBF in the non-dementia-WML group as compared with that in the controls. The WMLs in the left parietal region were severer in the SVD group than in the non-dementia-WML group. Conclusions: In patients with early-stage SVD without apparent brain atrophy, significant rCBF reduction in the bilateral pulvinar nuclei as compared with that in normal controls, and in the left pulvinar nucleus as compared with that in patients without dementia with WMLs was found.
Managing cardiotoxicity in anthracycline-treated breast cancers

Anthracyclines are among the most active chemotherapeutic agents in cancer treatment. Although infrequent, cumulative dose-dependent cardiotoxicity is nevertheless a significant side effect of this therapy resulting in reduced cardiac reserve or even frank cardiac failure. Although used in several types of malignancy, anthracyclines are most commonly used in breast cancer treatment. Importantly, recent advances have also seen the increasing use of another cardiotoxic agent, the monoclonal antibody trastuzumab, both in the metastatic as well as in the adjuvant breast cancer setting. This review discusses the relationship of cardiotoxicity and anthracycline use, particularly in the breast cancer setting, and explores available treatment options for the anthracycline-treated patients based on evidence from recent Phase III trials.
The Roles of Foreign Labour and Foreign Firms in the Irish Economy: An Empirical Analysis

The focus of this thesis is upon the role of foreign labour and foreign firms in the Irish economy. Chapter 1 presents an introduction to the overall thesis, while the historical context for the Irish economy is presented in Chapter 2. The empirical analysis presented in Chapter 3 explains occupational attainment in Ireland. With respect to occupational outcomes for foreign and indigenous workers, the Irish workers were found to be likely to occupy the professional posts. Foreign born workers who had resided in Ireland for less than ten years were less likely to find employment in the higher skilled occupations, while those workers who had resided for more than ten years in Ireland were likely to working in associate professional posts. Chapter 4 utilises a Mincerian wage equation to examine potential earnings differentials between Irish and non-Irish workers in the Irish labour market. Random effects estimates are analysed. The findings suggest that Irish workers earned less per hour than non-Irish workers, while non-Irish workers who took up Irish citizenship received higher levels of hourly pay then those non-Irish workers without Irish citizenship. Chapter 5 presents a production function analysis of firms in the Irish manufacturing sector. Using a Cobb-Douglas specification, firm nationality is found to have no impact upon output in the Irish manufacturing sector, while the output of Irish firms is linked to both family labour and outside piece workers, no such relationship is found for foreign firms.

Not All Promotions are Made Equal: From the Effects of a Price War to Cross-chain Cannibalization

textabstractDespite the huge amount of money allocated every year to sales promotions, brand managers still do not know how often and in what circumstances promotions are truly effective. This dissertation proposes an approach that allows managers to assess the impact of individual promotion events rather than the average effect of total promotional efforts. As such, more detailed information is gained on how promotions should be implemented. Moreover, sales promotions are not only evaluated in a business-as-usual environment, but their role and effectiveness during retailer induced price wars is also critically examined. As retailer competition tends to degenerate more often into price wars, this research offers recommendations to brand managers on whether they should accommodate retailers’ wishes to lower regular, list prices rather than focusing on temporary promotions. Finally, a brand manufacturer, when planning his promotional events for a retailer, should consider that a promotion can steal sales from rival supermarket chains. While these cross-chain effects are often negligible for the retailer, they are quite substantial for the manufacturer. Thus, to increase promotional effectiveness, a brand manager should carefully plan the promotional calendar across rival retailers.
Capital adequacy assessment in Indonesia : an empirical study

Many Indonesian banks suffered problems and some even failed in the early 1990s. This provided evidence that risk-based capital adequacy regulation in Indonesia had failed to prevent banks from taking excessive risks. Such observations provide the motivation for this thesis which seeks to identify the nature of bank risks in Indonesia and also analyses the operation of risk-based capital adequacy regulation in Indonesia. To obtain a general view of risk in Indonesian banks, this thesis includes an empirical study to identify the determinants of problem banks in Indonesia using a logit fixedeffect model. The model also can be used as an "early warning" device in banking supervision. This study finds that credit risk and operational risk contributed significantly to banking problems. State banks, non-foreign exchange banks and regional development banks are shown to be also sensitive to interest rate risk. Foreign exchange rate risk is less significant for banks (by group) in Indonesia. If we examine cases individually, however, there were some bank failures which were due to excessive foreign exchange rate risk. This thesis also finds that the adoption of risk-based capital adequacy regulation in Indonesia contains some deficiencies, such as focusing only on credit risk (ignoring market risk). This study suggests that market risk should be included in capital adequacy assessment and a number of alternative models of risk assessment [exponential weighted moving average (EWMA) and generalised autoregressive heteroscedasticity (GARCH)] are analysed. The results of the empirical study show that the inclusion of foreign exchange rate risk in capital adequacy assessment results in a higher capital requirement than that resulting from the application of the BIS's standardised methodology. This study also finds that the decay factor of 0.94 suggested by J. P. Morgan (J. P. Morgan, 1995, 1996) is irrelevant for [DR (Indonesian Rupiah) exchange rate returns. Additionally, assessment of foreign exchange rate risk using GARCH suggests a lower capital charge than that applicable under the BIS's standardised methodology and EWMA. The policy implications of these findings are also considered.
