Abstract
To improve accuracy of power system load forecasting, according to nonlinearity and uncertainty of load sequence, a power load forecasting method combined with kernel extreme learning machine (KELM) and adaptive variation bat optimization algorithm (AMBA) is proposed in this paper. The model determines mutation probability of the current optimal individual according to the population fitness variance and the value of the current optimal solution and the t-distribution variation is performed on the global optimal individual, and bat individual after mutation is subjected to secondary optimization. Then AMBA is used to optimize the network parameters of kernel function extreme learning machine, so that make full use of advantages of fast learning speed and generalization ability of KELM to realize rapid prediction of load. AMBA-KLEM model is used to predict load of Ningxia Power Grid, and the results are compared with ELM model and KELM model. The results show that the model has higher load prediction accuracy.

Authors: Shi Xiaosong , Cheng Yinglei , Xue Doudou 
Published: November 2019

Abstract
In order to improve the accuracy and efficiency of airborne LiDAR point cloud data classification algorithm, a classification algorithm of point cloud based on LightGBM was proposed, and the classification effect of the algorithm on urban point cloud data was tested. In this paper, LightGBM-1 classifier was used to roughly classify point cloud data firstly. Then ground points were extracted to normalize non-ground points. After that, multi-scale neighborhood features of building points and vegetation points were extracted, and then building points and vegetation points were finely classified by LightGBM-2 classifier. The algorithm was verified by urban point cloud data, and the classification effect was evaluated by analyzing classification accuracy and time. Experimental results show that, compared with other algorithms, this algorithm can effectively improve the effect of point cloud data, and realize the effective classification of point cloud data in urban areas.

Abstract
This paper presents a multi-information integrated landing navigation system for ship landing. It includes satellites, pseudolites, vision and inertial navigation systems. Pseudolites and satellite systems can provide the relative positions between plane and ship, and the vision system can get the relative positions and attitude by identifying targets on the runway. The airborne inertial navigation can provide the aircraft motion information, and the data link can receive the ship motion information. INS is selected as the federated filter reference system, and the satellite, pseudolite, visual and inertial navigation information are fused by the federated filter to Provide navigation information. Through designing simulation experiment by MATLAB. Under the set simulation conditions, the lateral and longitudinal position deviation between the aircraft and the ship is about 0.1m, and the relative vertical position deviation is within 0.3m, which achieve the precision requirement of shipboard landing. The simulation experiment shows that the multi-information integrated navigation method is practicable.

Abstract
Judgments of learning (JOL) pertain to introspective metamemory processes evaluating how well information is learned. Using a functional magnetic resonance imaging (fMRI) task, we investigated the neural substrates of JOL predictions in a group of 105 cognitively unimpaired older adults from the Harvard Aging Brain Study. Associations of JOL performance and its neural correlates with amyloid-β (Aβ) and tau pathology, two proteinopathies associated with Alzheimer’s disease (AD) and aging, were also examined. We found that trials judged as learned well relative to trials judged as learned less well (high JOL &gt; low JOL) engaged the ventromedial prefrontal cortex and precuneus, among other midline regions, in addition to bilateral hippocampi. In this cohort of older adults, greater levels of entorhinal tau deposition were associated with overestimation of memory performance and with lower fMRI signal in midline regions during predicted memory success. No associations with Aβ were found. The findings suggest that tau pathology in unimpaired older adults may play a role in altered metamemory processes. We discuss our findings in light of the hypothesis that JOLs are partially dependent on a process involving attempts to retrieve a correct answer from memory, as well as implications for clinical research investigating unawareness of memory performance (i.e., anosognosia) in patients with AD dementia.
Measuring Recovery in Deaf, Hard-of-Hearing, and Tinnitus Patients in a Mental Health Care Setting: Validation of the I.ROC
Authors: Roze Karin C M , Tijsseling Corrie , Rudd Bridey , Tiemens Bea G 
Published: November 2019

Abstract
This study was aimed at validating the Individual Recovery Outcomes Counter (I.ROC) for deaf, hard-of-hearing, and tinnitus patients in a mental health care setting. There is a need for an accessible instrument to monitor treatment effects in this population. The I.ROC measures recovery, seeing recovery as a process of experiencing a meaningful life, despite the limitations caused by illness or disability. A total of 84 adults referred to 2 specialist mental health centers for deaf, hard-of-hearing, and tinnitus adults in the Netherlands completed the Dutch version of I.ROC and 3 other instruments. A total of 25 patients refused or did not complete the instruments: 50% of patients using sign language and 18% of patients using spoken language. Participants completed the measures at intake and then every 3 months. In this sample I.ROC demonstrated good internal consistency and convergent validity. Sensitivity to change was good, especially over a period of 6 or 9 months. This study provides preliminary evidence that the I.ROC is a valid instrument measuring recovery for hard-of-hearing and tinnitus patients using spoken language. For deaf patients using sign language, specifically those with limited language skills in spoken and written Dutch, more research is needed.
Resection of a large primary left ventricle tumour by cardiac autotransplantation in a 2-month-old infant: a case report
Authors: Liu Yuhang , Wang Ning , Wen Ping , Zhou Gengxu 
Published: November 2019

Abstract

Background
Surgery is the fundamental method for the treatment of primary cardiac tumours. However, due to the inaccessibility of anatomy and the proximity of important structures, it is very difficult to completely resect tumours of the left atrium or left ventricle without damaging the normal tissues. Cardiac autotransplantation for the resection of cardiac tumours is carried out by taking out the heart from the body, resecting cardiac tumours, and then transplanting the heart back into the body.

Case summary
This article presents a successful case of cardiac autotransplantation for the complete resection of primary cardiac tumour in a 2-month-old infant and shares the noteworthy experience.

Discussion
Tumours located in the left atrium and left ventricle are difficult to be exposed because of their deep posterior location and proximity to important anatomical structures such as mitral valve and chordae tendineae. How to resect the tumours completely without damaging the normal tissues is a great challenge. This case proves that cardiac autotransplantation is a good solution for tumours that are difficult to be resected completely by orthotopic cardiac transplantation.
Within-Person Associations Between Attachment Security, Need Satisfaction and Psychological Adjustment in Daily Life of Older Adults
Authors: Martin Annika A , Horn Andrea B , Allemand Mathias 
Published: November 2019

Abstract

Objectives
Little is known about how attachment processes manifest within older adults in daily life and how these processes are associated with daily psychological adjustment. This study examined the within-person associations between states of attachment security and psychological adjustment. It is expected that this association is mediated by higher levels of satisfied needs in daily life.

Methods
Microlongitudinal self-report data were collected in a sample of 136 older adults ranged in age from 60 to 90 years (ageM = 70.45 years) across 10 days with daily morning and afternoon measurement occasions.

Results
Three main findings from multilevel analyses emerged. First, older adults showed significant within-person variation in attachment security, satisfaction of the needs for autonomy and competence, and psychological adjustment over time. Second, attachment security was positively associated with psychological adjustment within individuals. Third, both satisfaction of the needs for autonomy and competence mediated the within-person association between attachment security and psychological adjustment.

Discussion
The results suggest that attachment security is associated with the experience of autonomy and competence in daily life of older adults which in turn is related with better psychological adjustment.
Zeros of Holomorphic One-Forms and Topology of Kähler Manifolds
Authors: Schreieder Stefan 
Published: November 2019

Abstract
A conjecture of Kotschick predicts that a compact Kähler manifold X fibres smoothly over the circle if and only if it admits a holomorphic one-form without zeros. In this paper we develop an approach to this conjecture and verify it in dimension two. In a joint paper with Hao [10], we use our approach to prove Kotschick’s conjecture for smooth projective three-folds.

Published: November 2019

Abstract

Objectives
To determine the association of Neisseria gonorrhoeae antimicrobial resistance and genotypes using N. gonorrhoeae sequence typing for antimicrobial resistance (NG-STAR).

Methods
We characterized 124 N. gonorrhoeae isolates for their antimicrobial susceptibility profiles and NG-STAR ST characteristics using the guidelines of CLSI and EUCAST. The NG-STAR STs of seven loci were analysed. N. gonorrhoeae multiantigen sequence typing (NG-MAST) and MLST analysis was conducted in isolates with specific NG-STAR STs.

Results
NG-STAR differentiated 124 N. gonorrhoeae isolates into 84 STs, of which 66 STs were novel to the NG-STAR database. NG-STAR ST-199, ST-348, ST-428, ST-497 and ST-1138 were the predominant STs. Three N. gonorrhoeae isolates with ceftriaxone and cefixime MICs ≥1.0 mg/L were grouped as NG-STAR ST-233. NG-STAR ST-202 isolates (n=4) were associated with high azithromycin MICs and had an identical NG-MAST ST. The NG-STAR ST-348 group (n=5) comprised more isolates with reduced susceptibility to cefixime (n=4) than cefixime-susceptible isolates (n=1).

Conclusions
NG-STAR analysis differentiated N. gonorrhoeae isolates in settings with a high prevalence of antimicrobial resistance. Specific NG-STAR STs are associated with reduced susceptibility to ceftriaxone or cefixime and resistance to azithromycin in N. gonorrhoeae.

Published: November 2019

AbstractLymphocytes are one of the most important cells involved in the pathophysiology of psoriasis; therefore, the aim of this study was to assess the redox imbalance and protein modifications in the lymphocytes of patients with psoriasis vulgaris (PsV) or psoriatic arthritis (PsA). The results show a stronger shift in redox status to pro-oxidative conditions (observed as an increased reactive oxygen species level, a decrease in catalase activity and lower levels of glutathione peroxidase and vitamin E compared with healthy controls) in the lymphocytes of PsA than PsV patients. It is also favoured by the enhanced level of activators of the Nrf2 transcription factor in lymphocytes of PsV compared with decreased of these proteins level in PsA. Moreover, the differential modifications of proteins by lipid peroxidation products 4-oxononenal (mainly binding proteins) and malondialdehyde (mainly catalytic proteins with redox activity), promoted a pro-apoptotic pathway in lymphocytes of PsV, which was manifested by enhanced expression of pro-apoptotic caspases, particularly caspase 3. Taken together, differences in Nrf2 pathway activation may be responsible for the differential level of redox imbalance in lymphocytes of patients with PsV and PsA. This finding may enable identification of a targeted therapy to modify the metabolic pathways disturbed in psoriasis.
Radiation pattern analyses for seismic multi-parameter inversion of HTI anisotropic media
Authors: Gao Fengxia , Wang Yanghua 
Published: November 2019

Abstract
In seismic waveform inversion, selecting an optimal multi-parameter group is a key step to derive an accurate subsurface model for characterising hydrocarbon reservoirs. There are three parameterizations for the horizontal transverse isotropic (HTI) media, and each parameterization consists of five parameters. The first parameterization (P-I) consists of two velocities and three anisotropy parameters, the second (P-II) consists of five elastic coefficients and the third (P-III) consists of five velocity parameters. The radiation patterns of these three parameterizations indicate a strong interference among five parameters. An effective inversion strategy is a two-stage scheme that first inverts for the velocities or velocity-related parameters and then inverts for all five parameters simultaneously. The inversion results clearly demonstrate that P-I is the best parameterization for seismic waveform inversion in HTI anisotropic media.

Published: November 2019

AbstractObjectivePreliminary evidence supports the integration of type 1 diabetes (T1D) disease-specific factors into eating disorder risk models. The current study explored whether cross-sectional associations among constructs included in the modified dual pathway model of eating disorder risk for individuals with T1D are similar across sex among adolescents and young adults with T1D.MethodsOriginal study participants were recruited from the T1D Exchange Clinic Network, a U.S. registry of individuals with T1D. Online surveys included measures of general eating disorder risk factors, hypothesized T1D-specific risk factors, and a T1D-specific eating disorder questionnaire. The current study is a secondary analysis with the adolescents (13–17 years; n = 307; 46.9% female) and young adults (18–25 years; n = 313; 62.6% female) from the original sample. In the absence of strong measurement invariance for all measures of interest, sex-specific path models were estimated among the adolescent and young adult cohorts.ResultsOnly two paths emerged as significant in the female, but not male, adolescent model. In the young adult cohort, all significant paths were the same across sex.ConclusionsBoth general and T1D-specific risk factors are associated with disordered eating behaviors in the T1D population. Patterns of associations were similar across male and female youth with T1D, suggesting that sex-specific prevention approaches to disordered eating behaviors among T1D youth may not be warranted.
A statistical method to detect non-stationarities of gamma-ray burst jets
Authors: Budai A , Raffai P , Borgulya B , Dawes B A , Szeifert G , Varga V 
Published: November 2019

Abstract
We propose a method to detect possible non-stationarities of gamma-ray burst jets. Assuming that the dominant source of variability in the prompt gamma light curve is the non-stationarity of the jet, we show that there should be a connection between the variability measure and the characteristic angle of the jet derived from the jet break time of the afterglow. We carried out Monte Carlo simulations of long gamma-ray burst observations assuming three radial luminosity density profiles for jets and randomizing all burst parameters, and created samples of gamma light curves by simulating jets undergoing Brownian motions with linear restoring forces. We were able to demonstrate that the connection between the variability and the characteristic angle is an anti-correlation in case of uniform and power-law jet profiles, and a correlation in case of a Gaussian profile. We have found that as low as 50 (144) gamma-ray burst observations with jet angle measurements can be sufficient for a 3σ (5σ) detection of the connection. The number of observations required for the detection depends on the underlying jet beam profile, ranging from 50 (144) to 237 (659) for the four specific profile models we tested.
Diet and Adaptive Evolution of Alanine-Glyoxylate Aminotransferase Mitochondrial Targeting in Birds

Published: November 2019

AbstractAdaptations to different diets represent a hallmark of animal diversity. The diets of birds are highly variable, making them an excellent model system for studying adaptive evolution driven by dietary changes. To test whether molecular adaptations to diet have occurred during the evolution of birds, we examined a dietary enzyme alanine-glyoxylate aminotransferase (AGT), which tends to target mitochondria in carnivorous mammals, peroxisomes in herbivorous mammals, and both mitochondria and peroxisomes in omnivorous mammals. A total of 31 bird species were examined in this study, which included representatives of most major avian lineages. Of these, 29 have an intact mitochondrial targeting sequence (MTS) of AGT. This finding is in stark contrast to mammals, which showed a number of independent losses of the MTS. Our cell-based functional assays revealed that the efficiency of AGT mitochondrial targeting was greatly reduced in unrelated lineages of granivorous birds, yet it tended to be high in insectivorous and carnivorous lineages. Furthermore, we found that proportions of animal tissue in avian diets were positively correlated with mitochondrial targeting efficiencies that were experimentally determined, but not with those that were computationally predicted. Adaptive evolution of AGT mitochondrial targeting in birds was further supported by the detection of positive selection on MTS regions. Our study contributes to the understanding of how diet drives molecular adaptations in animals, and suggests that caution must be taken when computationally predicting protein subcellular targeting.

AbstractDNA polymerase β (pol β) selects the correct deoxyribonucleoside triphosphate for incorporation into the DNA polymer. Mistakes made by pol β lead to mutations, some of which occur within specific sequence contexts to generate mutation hotspots. The adenomatous polyposis coli (APC) gene is mutated within specific sequence contexts in colorectal carcinomas but the underlying mechanism is not fully understood. In previous work, we demonstrated that a somatic colon cancer variant of pol β, K289M, misincorporates deoxynucleotides at significantly increased frequencies over wild-type pol β within a mutation hotspot that is present several times within the APC gene. Kinetic studies provide evidence that the rate-determining step of pol β catalysis is phosphodiester bond formation and suggest that substrate selection is governed at this step. Remarkably, we show that, unlike WT, a pre-catalytic step in the K289M pol β kinetic pathway becomes slower than phosphodiester bond formation with the APC DNA sequence but not with a different DNA substrate. Based on our studies, we propose that pre-catalytic conformational changes are of critical importance for DNA polymerase fidelity within specific DNA sequence contexts.
