A Characteristic Parameter Matching Algorithm for Gravity-Aided Navigation of Underwater Vehicles

The gravity matching algorithm is a key of the gravity-aided inertial navigation system (INS). The traditional matching algorithm connects only the measured gravity anomaly data to the position of the carrier according to a certain method to correct the inertial error. The gravitational field characteristic parameters should also be considered in the matching algorithm to improve the matching accuracy and reduce the number of mismatching. Therefore, based on the vector matching algorithm, a characteristic parameter matching algorithm is proposed. This paper presents new methods to calculate the characteristic parameters and the range of particle filters to increase the accuracy of matching. The gravity anomaly value of each particle is calculated more accurately by the proposed method of continuous gravity anomaly. Due to the high short-time accuracy of inertial navigation, the final trajectory is obtained by rigid transformation of a series of positions indicated by the INS corresponding to the trajectory. Simulation results prove that when compared with the vector matching algorithm, the proposed method makes the matching results more accurate and more reliable.
Assessment of Relationship between Vitamin D Deficiency and Pain Severity in Patients with Low Back Pain: A Retrospective, Observational Study

Background: Vitamin D is associated with musculoskeletal function in our body, and its deficiency is a common health problem all over the world. Low back pain (LBP) is an important health problem in terms of low quality of life, loss of work power, and cost of diagnosis and treatment approaches. Aims: The purpose of this study is to investigate the relationship between pain severity and Vitamin D deficiency in patients who applied to pain polyclinic with LBP. Settings and Design: This was a retrospective, observational study. Subjects and Methods: The files of patients aged between 18 and 70 years who applied to our hospital between January and February 2018 were examined retrospectively by a specialist. Serum 25-hydroxyvitamin D (25(OH)D) level, Visual Analogue Scale (VAS), age, education level, marital status, working status, and body mass index (BMI) values recorded in patient files were included in the study. The limit value of Vitamin D was accepted as 20 ng/mL. Patients were divided into two groups according to their levels of Vitamin D. Patients with serum 25(OH)D levels below 20 ng/mL were considered as the deficiency of Vitamin D (Group 1) and patients with 20 ng/mL and over 20 ng/mL values were considered as normal in terms of Vitamin D (Group 2). Statistical Analysis Used: Descriptive statistical data were presented as mean, standard deviation, numbers, and percentage. There was no difference between the normally distributed group and the non-normally distributed group in terms of vitamin D levels. To compare the frequencies, the Chi-square test was used. To define the linear association between independent variables and Vitamin D level, Spearman's rho correlation coefficients were calculated. Results: The level of Vitamin D was measured in 98 patients aged 18–70 years who applied to our hospital's polyclinic due to LBP during the study period. The deficiency of vitamin was detected in 84 (85.7%) of the patients, while Vitamin D was found in 14 (14.3%) as normal. Groups were similar in terms of age, gender, BMI, educational level, marital status and working status (p> 0.05); however, there was a statistically significant difference between the two groups in terms of VAS score and levels of Vitamin D (P < 0.001 and P < 0.001, respectively). While there was a negative correlation between D vitamin level and VAS score (r = −0.594, P < 0.001), there was no correlation between age, gender, BMI, education level, marital status, and working status (P > 0.05). Conclusions: The deficiency of Vitamin D is often asymptomatic, and also, it can cause bone and muscle pain. In our study, we determined that the severity of pain increased in patients with LBP as the deficiency of Vitamin D increased. For this reason, we recommend to be evaluated the level of Vitamin D in patients with LBP.
DRAM Characterization under Relaxed Refresh Period Considering System Level Effects within a Commodity Server

Today’s rapid generation of data and the increased need for higher memory capacity has triggered a lot of studies on aggressive scaling of refresh period, which is currently set according to rare worst case conditions. Such studies analysed in detail the data-dependent circuit level factors and indicated the need for online DRAM characterization due to the variable cell retention time. They have done so by executing few test data patterns on FPGAs under controlled temperatures by using thermal testbeds, which however cannot be available in the field. Moreover, the existing studies were not able to reveal any system level effects, which may be excited under the execution of workloads on real systems and directly or indirectly affect DRAM reliability. In this paper, we develop an experimental framework based on a state-of-the-art 64-bit ARM based server with Linux OS, in which we enabled the DRAM characterization under relaxed refresh period by executing conventional test data patterns as well as popular HPC and Cloud workloads. Our results indicate that common test patterns are ineffective in identifying error-prone locations at low DRAM temperatures. Furthermore, we reveal that there is a strong correlation between the SOC utilization and DRAM reliability. By exploiting such findings, we developed a benchmark, which can indirectly stress the DRAM temperature and thus used for characterization in the field without needing any complicated thermal equipment. Our study shows that the refresh period can be relaxed by 35 times on such a commodity system with all errors being corrected by the available error correcting codes, resulting in 11.5% power savings on average.
Research on Coordination of Urbanization and Driving Forces of Urban Agglomeration in China Based on Nighttime Light Data

With the rapid development of urbanization in China.it is of great significance to achieve the healthy development of urbanization through studying the spatial-temporal characteristics and driving mechanism of coordinated urbanization development. Based on nighttime lighting data, this paper extract urban area of 334 cities in China from 1996 to 2016, and built land-population-economic coordination model by constructed a coupling coordination degree model. The results show that: (1) The land, population, and economic urbanization levels all show a continuous upward trend with time. The fastest growing one is the urbanization of land, with an annual growth rate of 14.2%. (2) The degree of coordination of urbanization in China is gradually increasing as time evolves. After 2010, the urbanization of China has got rid of disorder stage. (3) The regional differences of coordination level are significant and the coordination degree of coastal regions are far above the inland regions(4) Chinese urban agglomerations played a positive role in promoting the development of urbanization coordination. The development of urbanization coordination presented a ‘core-periphery’ trend, that is, the central city of urban agglomerations first reached a state of coordination, and then led the surrounding cities to realize the entire city. Coordination within the group.
Divergent artificial selection for female reproductive investment has a sexually concordant effect on male reproductive success

Depending on the genetic architecture of male and female fitness, sex‐specific selection can have negative, positive, or neutral consequences for the opposite sex. Theory predicts that conflict between male and female function may drive the breakdown of intrasexual genetic correlations, allowing sexual dimorphism in sexually antagonistic traits. Reproductive traits are the epitome of this, showing highly differentiated proximate functions between the sexes. Here we use divergent artificial selection lines for female reproductive investment to test how female‐specific selection on a sex‐limited trait affects male reproductive success in a precocial bird, the Japanese quail (Coturnix japonica). We demonstrate that selection for increased egg investment in females positively affects male reproductive success both in competitive and non‐competitive mating situations. This increased reproductive success was linked to a relatively larger left testis in males originating from lines selected for high female reproductive investment. Given that female quail have functional gonads only on their left side, this correlated response indicates that selection has acted on the shared developmental basis of male and female gonads. Our study thereby provides evidence for a positive genetic correlation between key reproductive traits in males and females despite a high degree of sexual dimorphism, and suggests that, in this system, selection on reproductive function is sexually concordant.
Living donor liver transplant from an HIV-positive individual to an HIV-negative individual: could this become a new reality?

Transplant centers worldwide face a huge shortage of organs, resulting in long-waiting lists even for the sickest patients. Various innovations have been and are being considered for expansion of the donor pools. In the United States, the HIV Organ Policy Equity Act, enacted in 2013, allowed transplantation of organs from HIVpositive living and deceased donors to HIV-positive individuals with end-stage organ disease. Concomitant with an increase in the prevalence of end-stage organ disease among HIV-infected individuals, there has been a marked rise in the demand for these organs. Today, patients with well controlled HIV on antiretroviral therapy (ART) who do not have opportunistic infections or cancer, and with specified minimum CD4þ cell counts are clearly appropriate transplant candidates [1]. Although the clinical experience with such transplants is still limited, there are encouraging results from a small number of deceased-donor kidney transplants from HIVpositive to HIV-positive persons in South Africa, as well as additional case reports from the United Kingdom and Canada; there have also been presentations of the results of HIV-positive-to-HIV-positive liver transplantations in the United States [2–6]. All so far suggest that this strategy is feasible, and that these organ transplant outcomes are comparable with those of other transplanted populations.
Numerical Modeling of a Nonlinear Four-Phase Switched Reluctance Machine

Switched reluctance machine (SRM) acts as a suitable choice for electromechanical conversion of wind energy because of its wide range of speed operation, thermal robustness high performances, and reduced cost. This paper presents a numerical modeling of nonlinear inductance and torque for doubly salient switched reluctance machine (DSSRM) with finite element method (FEM) using the femm which considers magnetic saturation. The results obtained have been compared with other study that showed the same nonlinear behavior of phase inductance and phase torque.
LXRα Promotes Hepatosteatosis in Part Through Activation of MicroRNA‐378 Transcription and Inhibition of Ppargc1β Expression

Nonalcoholic fatty liver disease (NAFLD) is a major risk factor of many end‐stage liver diseases. Alterations in microRNA expression have been reported in patients with NAFLD. However, the transcriptional mechanism(s) of dysregulated microRNAs under the state of NAFLD is poorly described, and microRNAs that regulate the pathogenesis of NAFLD synergistically with their regulators remain unknown. Here we report that microRNA‐378 expression is significantly increased in fatty livers of mice and patients with NAFLD. Although microRNA‐378 locates within the intron of Ppargc1β (peroxisome proliferator‐activated receptor γ coactivator 1‐beta), there was a significant uncoupling of Ppargc1β mRNA and microRNA‐378 levels in both sources of fatty livers. Further studies identified a full‐length primary transcript of microRNA‐378. LXRα (liver X receptor alpha) functioned as a transcription activator of microRNA‐378 and a repressor of Ppargc1β transcription. It is known that miR‐378 is an inhibitor of fatty acid oxidation (FAO) and the function of Ppargc1β is opposite to that of miR‐378. GW3965 treatment (LXRα agonist) of murine hepatocytes and mice increased microRNA‐378 and reduced Ppargc1β, which subsequently impaired FAO and aggravated hepatosteatosis. In contrast, additional treatment of miR‐378 inhibitor or Ppargc1β, which knocked down increased miR‐378 or recovered expression of Ppargc1β, offset the effects of GW3965. Liver‐specific ablation of Lxrα led to decreased miR‐378 and increased Ppargc1β, which subsequently improved FAO and reduced hepatosteatosis. Conclusion: Our findings indicated that miR‐378 possesses its own transcription machinery, which challenges the well‐established dogma that miR‐378 transcription is controlled by the promoter of Ppargc1β. LXRα selectively activates transcription of miR‐378 and inhibits expression of Ppargc1β, which synergistically impairs FAO. In addition to lipogenesis, impaired FAO by miR‐378 in part contributes to LXRα‐induced hepatosteatosis.
Bandgap Engineering of Black Phosphorus-Based Nano structures

In this work, first-principles calculations based on Density Functional Theory (DFT) were employed in order to investigate the electronic properties of Black Phosphorus and its 2D and 1D derivatives, named Phosphorene and Phosphorene Nanoribbons (PNRs) respectively. The electronic structures of the black phosphorus-based nanostructures were firstly examined. Our results demonstrate that all dimensions behave as semiconductors except for the zigzag nanoribbons which are shown to be metals. Furthermore, we extended our study to include different strategies to engineer the bandgap of the two-dimensional phosphorene and the one-dimensional phosphorene nanoribbons either by stacking a multiple number of the phosphorene layers, exercising a tensile or compressive strain or by edge-passivating the phosphorene nanoribbons with Hydrogen. Our study reveals that the bandgaps and the electronic properties of these black phosphorus-based nanostructures are very flexible and several approaches could be adopted in order to engineer them.
A Rare Case of Isolated Intracranial Rosai–Dorfman Disease Mimicking Optic Nerve Meningioma: A Case Report and Literature Review

Sinus histiocytosis with massive lymphadenopathy, or Rosai–Dorfman disease (RDD), was first described in 1969 as a reactive condition of unknown etiology that is characterized by a proliferation of histiocytes exhibiting emperipolesis of both lymphocytes and plasma cells. It usually presents with painless cervical lymphadenopathy either with or without extranodal manifestations. Intracranial involvement of this disease is extremely rare. Intracranial RDD occurs in <5% of all patients with extranodal disease. Here, we report a case of RDD with isolated intracranial involvement. A 67-year-old male presented with a long-standing headache, retro-ocular pain, and progressive visual loss of the left eye. Magnetic resonance imaging showed features of optic nerve meningioma. The histopathology revealed sheets of histiocytes displaying emperipolesis. These histiocytes were S100 positive; however, a CD1a and epithelial membrane antigen were negative.
Hospitalization for Ambulatory Care Sensitive Conditions in children under five years old in Santa Catarina State , Brazil , 2012 : a descriptive study *

Objective: to describe proportions and rates of hospitalization for Ambulatory Care Sensitive Conditions (ACSC) among children under 5 years old, in Santa Catarina State, Brazil, 2012. Methods: this is a descriptive study using Brazilian National Health Service Hospital Information System (SIH/SUS) data, classified according to the Brazilian ACSC List. Results: a total of 32,445 children aged <5 years old were hospitalized, 25,7% of whom were ACSC cases, representing a rate of 20.1/1,000 inhabitants in the same age group; the main causes were infectious gastroenteritis and complications (26.7%), bacterial pneumonia (22.2%) and pulmonary diseases (16.9%); there was a higher hospitalization rate due to ACSC in males (21.1/1,000), and in children <1 year old (43.8/1,000). Conclusion: The results showed that the State of Santa Catarina had lower rates and proportions than those found in other Brazilian studies, even though ACSC were the cause of one quarter of hospitalizations in children aged <5 years.
Setting Parameters of an Erosion Test Bench for Solar Reflectors

Concentrated Solar Power (CSP) components are often subject to different degradation phenomena related to the environment in which they are exposed. The later is often an arid environment characterized by high wind velocity and intense turbulence with large quantities of sand and dust that could affect solar components, especially, reflectors. The contact of sand particles with solar reflectors can produce erosion defects that could seriously reduce the optical properties of these components. For a better understanding of erosion mechanisms, a horizontal test bench was designed to conduct erosion tests on solar reflectors using sand particles. It was calibrated assessing different parameters to simulate the real conditions observed while solar reflectors are in service. Several tests were conducted to adjust the air flow homogeneity, the impingement angle, the wind velocity values and the concentration of sand particles. Tests on solar mirrors were carried out to check the reliability and the repeatability of the test bench results with all the parameters used.
No evidence that kin selection increases the honesty of begging signals in birds

Providing plausible mechanisms to explain variation in the honesty of information communicated through offspring begging signals is fundamental to our understanding of parent–offspring conflict and the evolution of family life. A recently published research article used comparative analyses to investigate two long‐standing hypotheses that may explain the evolution of begging behavior. The results suggested that direct competition between offspring for parental resources decreases begging honesty, whereas indirect, kin‐selected benefits gained through saving parental resources for the production of future siblings increase begging honesty. However, we feel that evidence for a role of kin selection in this context is still missing. We present a combination of arguments and empirical tests to outline alternative sources of interspecific variation in offspring begging levels and discuss avenues for further research that can bring us closer to a complete understanding of the evolution of offspring signaling.
Context-Aware Text-Based Binary Image Stylization and Synthesis

In this work, we present a new framework for the stylization of text-based binary images. First, our method stylizes the stroke-based geometric shape like text, symbols, and icons in the target binary image based on an input style image. Second, the composition of the stylized geometric shape and a background image is explored. To accomplish the task, we propose legibility-preserving structure and texture transfer algorithms, which progressively narrow the visual differences between the binary image and the style image. The stylization is then followed by a context-aware layout design algorithm, where the cues for both seamlessness and aesthetics are employed to determine the optimal layout of the shape in the background. Given the layout, the binary image is seamlessly embedded into the background by texture synthesis under a context-aware boundary constraint. According to the contents of binary images, our method can be applied to many fields. We show that the proposed method is capable of addressing the unsupervised text stylization problem and is superior to state-of-the-art style transfer methods in automatic artistic typography creation. Besides, extensive experiments on various tasks, such as visual-textual presentation synthesis, icon/symbol rendering, and structure-guided image inpainting demonstrate the effectiveness of the proposed method.
Exploring the Relative Importance of Normative and Distinctive Organizational Preferences as Predictors of Work Attitudes

Profile approaches to operationalizing person-organization (P-O) fit as the within-person correlation between an individual’s ideal organization characteristics and their actual organization characteristics regularly find strong associations between P-O fit and an individual’s work attitudes. However, profile correlation indices and other overall indices of P-O fit regularly confound normative and distinctive components of fit—that is: the extent to which the person’s organization culture fits the culture that would be preferred by the average person, and the extent to which their organization fits an individual’s idiosyncratic preferences. Here, we show how these two normative and distinctive P-O fits can be differentiated and related to an individual’s attitudes about their organization experience. Utilizing data from 723 participants from four samples, we show that the degree to which an individual’s description of their organizational culture corresponds to the normative ideal organizational culture may account for nearly all of the large associations regularly found between overall P-O fit indices and positive workplace attitudes. In contrast, the degree of fit between an individual’s work environment and their distinctive or idiosyncratic preferences may play a relatively small role in predicting the positive workplace attitudes. We discuss broader implications for the design of organizational cultures and the more general understanding of the nature of P-O fit.
