Efficient lattice-reduction-aided conditional detection for MIMO systems

Two near-optimal, low-complexity latticereduction- aided (LRA) conditional detectors are proposed for multiple-input multiple-output (MIMO) systems. The reduction is performed only on a selection of columns of the channel matrix and conditional optimization is performed on the remaining ones. In the proposed schemes, the best submatrix for conditional detection is selected by considering all possible submatrices and choosing the one that gives the best metric. For quasi-static channels, where the cost of lattice reduction can be negligible over the whole packet over which the channel is constant, the complexity of the proposed schemes is only linear in the size of the QAM modulation used. The near-optimal error performances of the proposed schemes are verified by analysis and simulations.
A Probabilistic Dynamic Material Flow Analysis Model for Chinese Urban Housing Stock

The stock‐driven dynamic material flow analysis (MFA) model is one of the prevalent tools to investigate the evolution and related material metabolism of the building stock. There exists substantial uncertainty inherent to input parameters of the stock‐driven dynamic building stock MFA model, which has not been comprehensively evaluated yet. In this study, a probabilistic, stock‐driven dynamic MFA model is established and China's urban housing stock is selected as the empirical case. This probabilistic dynamic MFA model has the ability to depict the future evolution pathway of China's housing stock and capture uncertainties in its material stock, inflow, and outflow. By means of probabilistic methods, a detailed and transparent estimation of China's housing stock and its material metabolism behavior is presented. Under a scenario with a saturation level of the population, urbanization, and living space, the median value of the urban housing stock area, newly completed area, and demolished area would peak at around 49, 2.2, and 2.2 billion square meters, respectively. The corresponding material stock and flows are 79, 3.5, and 3.3 billion tonnes, respectively. Uncertainties regarding housing stock and its material stock and flows are non‐negligible. Relative uncertainties of the material stock and flows are above 50%. The uncertainty importance analysis demonstrates that the material intensity and the total population are major contributions to the uncertainty. Policy makers in the housing sector should consider the material efficiency as an essential policy to mitigate material flows of the urban building stock and to lower the risk of policy failures.
Upper Cervical Involvement in Rheumatoid Arthritis

Atlanto-axial dislocation and upward migration of the odontoid were studied in patients with rheumatoid arthritis treated conservatively and those treated by atlanto-axial posterior fusion. Upward migration of the odontoid was evaluated by Ranawat's and Redlund-Johnell's methods after determining the normal range in healthy Japanese adults. Of the 100 patients treated conservatively, atlantoaxial dislocation was found in 49% and upward migration of the odontoid in 26% by the former method, and in 8% by the latter method. The detection rate of these lesions increased with the increase in the duration of the disease and progression of rheumatoid lesions. Abnormal Ranawat values are associated with lesions in the C1–C2 segment and abnormal Redlund-Johnell values with 0–C2 lesions. The latter suggests severe conditions and seems to be a useful indicator for the diagnosis of upward migration of the odontoid in our study. Though rheumatoid lesions in the upper cervical spine mainly involved the C1–C2 level, marked deterioration of the atlanto-occipital joints was also occasionally observed. Therefore, in surgical treatment, attention should be paid also to this region. Patients with abnormal Redlund-Johnell values require spinal fixation including the occipital bone.
Should I Stay or Should I Go Now? Or Should I Wait and See? Influences on Wildfire Evacuation Decisions

As climate change has contributed to longer fire seasons and populations living in fire‐prone ecosystems increase, wildfires have begun to affect a growing number of people. As a result, interest in understanding the wildfire evacuation decision process has increased. Of particular interest is understanding why some people leave early, some choose to stay and defend their homes, and others wait to assess conditions before making a final decision. Individuals who tend to wait and see are of particular concern given the dangers of late evacuation. To understand what factors might influence different decisions, we surveyed homeowners in three areas in the United States that recently experienced a wildfire. The Protective Action Decision Model was used to identify a suite of factors previously identified as potentially relevant to evacuation decisions. Our results indicate that different beliefs about the efficacy of a particular response or action (evacuating or staying to defend), differences in risk attitudes, and emphasis on different cues to act (e.g., official warnings, environmental cues) are key factors underlying different responses. Further, latent class analysis indicates there are two general classes of individuals: those inclined to evacuate and those inclined to stay, and that a substantial portion of each class falls into the wait and see category.
Non-R&D-based innovation activities and performance in Chinese SMEs: the role of absorptive capacity

To what extent can non-R&D-based innovation contribute to innovation performance in small- and medium-sized enterprises (SMEs)? To answer this question, this study investigates the moderating role of absorptive capacity in the relationships between three non-R&D-based innovation activities and firms’ innovation performance, namely ‘technology adoption,’ ‘imitation and minor modification,’ and ‘innovative marketing. ’ Using data on 329 Chinese manufacturing SMEs, we find that the absorptive capacity of SMEs positively moderates the relationship between innovative marketing and innovation performance. However, the absorptive capacity of SMEs negatively moderates the relationship between imitation and minor modification and their innovation performance. These findings contribute to understanding the effects of non-R&D-based innovation activities, and the role of SMEs’ absorptive capacity in a non-R&D context.
The role of apolipoprotein E and glucose intolerance in gallstone disease in middle aged subjects

BACKGROUND The polymorphism of apolipoprotein E has been suggested to be associated with the cholesterol content of gallstones, the crystallisation rate of gall bladder bile, and the prevalence of gallstone disease (GSD). AIMS To investigate whether apolipoprotein E polymorphism modulates the susceptibility to GSD at the population level and to study the possible associations between impaired glucose tolerance, diabetes, and GSD. METHODS Apolipoprotein E phenotypes were determined in a middle aged cohort of 261 randomly selected hypertensive men, 259 control men, 257 hypertensive women, and 267 control women. All subjects without a documented history of diabetes were submitted to a two hour oral glucose tolerance test (OGTT). GSD was verified by ultrasonography. RESULTS In women with apolipoprotein E2 (phenotypes E2/2, 2/3, and 2/4) compared with women without E2 (E3/3, 4/3, and 4/4), the odds ratio for GSD was 0.28 (95% confidence interval 0.08–0.92). There was no protective effect in men. The relative risk for GSD was 1.2 (0.8–1.7) for hypertensive women and 1.8 (1.0–2.7) for hypertensive men. In a stepwise multiple logistic regression model, E2 protected against GSD in women, whereas two hour blood glucose in the OGTT, serum insulin, and plasma triglycerides were risk factors. Elevated blood glucose during the OGTT was also a significant risk factor for GSD in men. CONCLUSIONS The data suggest that apolipoprotein E2 is a genetic factor providing protection against GSD in women. In contrast, impaired glucose tolerance and frank diabetes are associated with the risk of GSD.

Pension Systems and Income Inequality among the Elderly in Europe

Pension system regulation has grown to a complex field of study; many actors have been setting up institutional arrangements, which serve two main purposes: poverty prevention and income maintenance in old age. This doctoral dissertation addresses four major research questions: Why is there cross-national variation of income received by the elderly? What implications do different institutional pathways of pension systems have for the income situation? What role do non-public pension systems play in the income-mix and for the development of inequalities? Which developments can be observed in the public-private income mix and generosity of the pension system? This monograph is a cross-national study of past and current pension system legislation and its relevance for the current income mix of the elderly; it is structured in two main blocks. A first part outlines a comprehensive framework that points to within- and between-country variation in old-age income security, which is an outcome of pension system characteristics, labour market attachment, and living arrangements. A second part focuses on comparative country-case studies in Europe that evaluate the interactions between specific pension systems characteristics set up by the various actors involved in pension system design. A specific emphasis is placed on the diversity of second-tier schemes and the growing relevance of multipillar pension systems.
Predictive value of stabilometry and fear of falling on falls in postmenopausal women

Abstract Objectives Falls are one of the leading causes of fractures and impaired quality of life in the elderly, and they are related to balance deficit and to fear of falls. The purpose of our study is to evaluate predictors of falls in the 50–65-year-old postmenopausal population. Methods A prospective cohort study was conducted on 96 postmenopausal women. Fear of falling and postural stability were assessed by using the FES-I (Falls Efficacy Scale-International) and a force platform, respectively. Fall frequency was determined in the 12-month follow-up study period. Multivariate logistic regression was used to identify predictive factors of falls. Results Fear of falls, the FES-I scale and four stabilometric parameters, specifically under eyes-closed condition, were significantly higher in the group of fallers. The root mean square amplitude in the medial–lateral direction with eyes closed (RMSXec) (odds ratio 5.1, 95% confidence interval (CI) 1.6–15.5, p = 0.004) and FES-I (odds ratio 3.4, 95% CI 1.1–10.5, p = 0.026) were the best independent predictive factors of the risk of falling. Conclusions RMSXec > 0.133 was the best predictive factor for falls in our group of 50–65-year-old postmenopausal women studied, and a FES-I score > 20 could predict falls in this population.
Appearance of Eosinophilic Granule Cells as Pathological Changes in the Uteri of Two Aged Virgin Donryu Rats

The morphological features of cells containing eosinophilic granules (EG cells) present as pathological changes in the uteri of 2 aged virgin Donryu rats were described and compared with granulated metrial gland (GMG) cells of a pregnant rat. Microscopically, EG cells distributed diffusely from the mesometrial triangle to the subendometrium with partly focal accumulation in Case 1 and infiltrated diffusely from the endometrium to the serosa without any clumping in Case 2. They were large cells with eosinophilic and hyaline intracytoplasmic granules, positive for the periodic acid-Schiff reaction. Both EG and GMG cells reacted positively to concanavalin A, wheat germ agglutinin, and phytohemagglutinin on lectin histochemical investigation, although common results were not always obtained for immunohistochemistry. These results show that EG cells are morphologically similar to GMG cells, suggesting a possibility that EG cells are GMG cells. EG cells were without neoplastic properties or pronounced cell-proliferative activity. In Case 1, histological changes of the ovaries and vagina were indicative of a pseudopregnant status. In Case 2, the rat had been maintained under abnormal hormonal conditions, and no evidence of any pseudopregnant-like status was found. These results suggest, thus, that the appearance of EG cells is evidence of a reactive pathological condition in the uteri of aged virgin rats, although the precise pathogenesis and biological significance of EG cells remain to be determined.
The relationship between intellectual capital and earnings quality: evidence from listed firms in Bahrain Bourse

This paper examines the relationship between the intellectual capital and earnings quality for the listed firms in Bahrain Bourse. This paper is applying the modified Jones model (Jones, 1991) in order to examine the relationship between the intellectual capital and earnings quality. The outcomes of this paper conclude to have high level of intellectual capital and earnings quality as well as a positive relationship between them in all listed firms at Bahrain Bourse. The findings show significant support for the current debate regarding the relationship between the intellectual capital and earnings quality in the Bahraini market. This research is expected to serve as a guide for the regulatory bodies such as Bahrain Bourse, financial institutions management as well as academic researchers in Bahrain.
Insight and Personal Narratives of Illness in Schizophrenia

Abstract Insight in schizophrenia tends to be assessed as the degree to which one possesses specific knowledge. It therefore often fails to account for the fact that awareness of illness is an inextricable part of a personal narrative and may be incoherent or incomplete for many different narrative reasons. Accordingly, we have developed a means of eliciting narratives of illness: the Indiana Psychiatric Illness Interview, and a method for rating the coherence of those narratives: the Narrative Coherence Rating Scale. In this article we describe these methods and present data on their reliability and validity in a study of the illness narratives of 33 outpatients with schizophrenia or schizoaffective disorder. Results suggest our measures possess sufficient internal consistency and good to excellent interrater reliability. Additionally, as predicted, our measures of narrative coherence were significantly correlated with traditional measures of insight and with measures of cognitive impairment and hopelessness gathered earlier.
Accumulating too much stuff: what is hoarding and what is not?

Objective: This paper considers the meaning of the terms hoarding, collecting and accumulation, with a focus on what is abnormal and what is not. Conclusions: Hoarding is an adaptive behaviour. When hoarding is excessive and interferes with people’s lives, it is a disorder. A central feature of hoarding disorder is accumulation of items due to unwillingness to discard them. This must be distinguished from abnormal accumulation of material caused by poor motivation or unawareness concerning the need to discard.
Price Level Convergence: Croatia, Transition Countries and the EU

This paper analyses changes in price levels and real income in European countries on the basis of data from the International Comparison Project (ICP) and estimates the potential pressures on prices ensuing from the convergence process. Regression results for determinants of price levels indicate the importance of the Balassa-Samuelson effect for an explanation of observed differences in price levels across countries. A particular emphasis is put on the position of Croatia in international comparisons by using disaggregated data collected within the ICP. The paper suggests that a relatively high level of Croatian prices could be an advantage in the EU integration process due to lesser needs for future corrections of the exchange rate and prices. The presented regression estimate of factors of price level convergence indicates that over the next few years Croatia, among all European transition countries, may experience the least upward pressure on the general price level.
The Shifting Demand for Housing by American Renters and its Impact on Household Budgets: 1940–2010

From 1940 to 1960 across 20 large U.S. cities, rental housing's price fell, renters’ incomes rose, rent's share in household budgets fell, and, as expected, renters’ real housing consumption increased. From 1970 to 2010, rental housing's price increased, renters’ incomes decreased, but, unexpectedly, renters’ real housing consumption increased. We find neither demographics nor housing supply factors account for the anomalous post-1970 increase in renters’ housing consumption. We conclude that after 1970 there was a nationwide increase in renters’ preferences for housing consumption. With incomes falling, renters increased housing consumption by decreasing consumption of other necessities including food, clothing, and transportation.
WD Repeat-containing Protein 5 (WDR5) Localizes to the Midbody and Regulates Abscission*

Background: WDR5 is a protein known for its role in the epigenetic control of gene expression. Results: During cytokinesis, WDR5 resides at the midbody in the absence of chromatin and promotes normal abscission. Conclusion: WDR5 is a midbody component and regulates the final steps of cytokinesis. Significance: WDR5 may have additional functions and binding partners outside of the cell nucleus. Cytokinesis partitions the cytoplasm of a parent cell into two daughter cells and is essential for the completion of cell division. The final step of cytokinesis in animal cells is abscission, which is a process leading to the physical separation of two daughter cells. Abscission requires membrane traffic and microtubule disassembly at a specific midbody region called the secondary ingression. Here, we report that WD repeat-containing protein 5 (WDR5), a core subunit of COMPASS/MLL family histone H3 lysine 4 methyltransferase (H3K4MT) complexes, resides at the midbody and associates with a subset of midbody regulatory proteins, including PRC1 and CYK4/MKLP1. Knockdown of WDR5 impairs abscission and increases the incidence of multinucleated cells. Further investigation revealed that the abscission delay is primarily due to slower formation of secondary ingressions in WDR5 knockdown cells. Consistent with these defects, midbody microtubules in WDR5 knockdown cells also display enhanced resistance to depolymerization by nocodazole. Recruitment of WDR5 to the midbody dark zone appears to require integrity of the WDR5 central arginine-binding cavity, as mutations that disrupt histone H3 and MLL1 binding to this pocket also abolish the midbody localization of WDR5. Taken together, these data suggest that WDR5 is specifically targeted to the midbody in the absence of chromatin and that it promotes abscission, perhaps by facilitating midbody microtubule disassembly.
Comparison of Living and Bedrooms in Terms of House Dust Mites in the Province of Erzincan, Turkey

Abstract The most important factors in development of symptoms such as allergic asthma, rhinitis, conjunctivitis, and dermatitis in atopic persons are the allergens of house dust mites. The objective of this study was to compare living rooms and bedrooms, and woolen and spring mattresses in terms of the number and species of mites in houses in the province of Erzincan, Turkey. In total, 74 dust samples were collected from living rooms and bedrooms of 37 randomly selected houses from various districts of the city. All examined houses were positive for house dust mites. In total, 5,210 mites were isolated, 1,058 from the living rooms and 4,152 from the bedrooms, and the differences were statistically significant (P < 0.05). Of 4,152 mites detected in bedrooms, 1,330 (32%) were isolated from 31 spring mattresses and 2,822 (68%) from 6 woolen mattresses (P < 0.001). The study identified 14 families, 17 genera, and 16 species belonging to Astigmata, Prostigmata, and Oribatida. Of these, Dermatophagoides pteronyssinus (Trouessart) was the dominant species: living rooms, 63.3%; bedrooms, 74.4%; woolen mattresses, 84.6%; and spring mattresses, 52.8%. This was followed by Lepidoglyphus destructor (Schrank) (9.8%), Dermatophagoides farinae Hughes (5.1%), Tyrophagus putrescentiae (Schrank) (4.3%), and Acarus siro L. (2.5%) in living rooms; L. destructor (11.2%), Euroglyphus maynei (Cooreman) (4.2%), D. farinae (3.8%), and T. putrescentiae (1.0%) in bedrooms; L. destructor (11.8%), D. farinae (2.1%), E. maynei (0.3%), and T. putrescentiae (0.2%) in woolen mattresses; and E. maynei (12.5%), L. destructor (9.9%), D. farinae (7.5%), and T. putrescentiae (2.7%) in spring mattresses.
Metabolism and excretion of methylamines in rats.

Experiments were performed with rats to examine the sources and disposition of dimethylamine (DMA), trimethylamine (TMA), and trimethylamine N-oxide (TMAO), all potential substrates for in vivo nitrosation to form N-nitrosodimethylamine (NDMA), a potent carcinogen. When bolus doses of [14C]DMA or [14C]TMA were given ip, recovery of radioactivity in the urine was essentially complete, and respiratory excretion, fecal excretion, and accumulation in tissues of these amines or their metabolites were negligible. Urine analysis following doses of stable isotopes showed that DMA was not converted to TMA or TMAO. Varying amounts of TMA were oxidized to TMAO, the fraction oxidized decreasing at higher doses of TMA. Ingestion and excretion of naturally occurring methylamines were monitored over a 5-day period in separate groups of normal and germ-free rats. The results of these metabolic balance studies indicate that there is net synthesis of DMA by gut bacteria and net consumption of TMAO by endogenous processes. The net intake or excretion of TMA and TMAO observed in normal and germ-free rats is consistent with bacterial synthesis of TMA followed by its almost complete oxidation to TMAO. Blood concentrations of DMA and TMA were measured in rats for 8 hr following < 5, 100, or 1000 mumol bolus i.v. or ip doses of radioisotopes or stable isotopes. At any given dose of DMA or TMA, the decay in blood concentration was approximately monoexponential. At the lowest (most physiologic) dose the apparent volume of distribution (VD) for DMA was larger than that for TMA. Both values of VD greatly exceeded the size of the animals, suggesting that DMA and TMA are highly concentrated at one or more locations in the body. This was confirmed by measurements in tissue homogenates sampled 1 hr after a dose. The overall handling of methylamines by rats is generally consistent with observations in humans. The presence of high local concentrations of DMA and TMA at various extragastric sites merits further investigation in connection with the potential for endogenous nitrosation of these methylamines to form NDMA.
Hypercatabolism of IgG in mice with lupus-like syndrome

The metabolism of radioiodinated mouse IgG was studied in mice with lupus-like syndrome before and after the onset of the disease. Before the onset of the disease, the pharmacokinetic parameters of IgG in MLR-lpr and Pristane-primed Balb/c mice were within the normal range of values. After the onset of the disease a considerable increase in the catabolic rate of IgG was recorded abbreviating its half life to less than one third of the normal value. The increased catabolism of IgG could not be related to the concentration-catabolism effect or to the presence of rheumatoid factor and autoantibody or to the IgG loss through the kidney and gastrointestinal tract. The hypercatabolism of IgG was explained by disease-induced impairment of the function of the receptor FcRn, which regulates the homeostasis of IgG.
