High-precision ultrasound imaging of void defects is critical for the performance and safety assessment ballastless track structures. The sound propagation velocity each layer in structure quite different. However, traditional concrete Synthetic Aperture Focusing Technique (SAFT) method based on assumption that has a single constant shear wave velocity. Thus, it not suitable ultrasonic multilayer In this paper, Multilayer SAFT high-precision proposed. It ray-tracing technique uses Fermat...

A subsample 51 participants then asked to complete again along with another set questionnaires. five‐factor model 20‐item short showed good fit, internal consistency, and test‐retest reliability. also provided validity, showing correlations other variables in expected directions. ast‐ ositive positively correlated...

Mental time travel refers to the ability recall past events and imagine possible future events. Schizophrenia (SCZ) patients have problems in remembering specific personal experiences imagining what will happen future. This study aimed examine episodic thinking SCZ spectrum disorders including individuals with schizotypal personality disorder (SPD) proneness who are at risk for developing SCZ. Thirty-two patients, 30 SPD individuals, 33 healthy controls participated study. The Sentence...

Time perspective is a fundamental dimension of the psychological time construct, with pervasive and powerful influence on human behavior. However, developmental trajectory across lifespan remains unclear. The current study aimed to portray all dimensions perspectives from children older adults in large sample. A total 1,901 individuals (aged 9-84 years) completed measures perspective. They were then divided into five age groups: children, teenagers, young adults, middle-aged adults. Results...

Background and Objective: Glucose fluctuation (GF) has been reported to induce renal injury diabetic nephropathy (DN). However, the mechanism still remains ambiguous. Mitochondrial energy metabolism, especially aerobic glycolysis, a hotspot of DN research for decades. The activation HIF-1α/miR210/ISCU/FeS axis provided new explanation glycolysis. Our previous studies indicated quercetin as potential therapeutic drug DN. This study aims evaluate levels glycolysis repressive effect via in cell...

In 2022, the US Food and Drug Administration enacted final regulations to establish category of over-the-counter (OTC) hearing aids aimed at reducing barriers access health care for individuals with self-perceived mild moderate loss. However, given infancy this device category, effectiveness OTC in real-world environments is not yet well understood.

The Iowa Gambling Task (IGT) simulates uncertain gains and losses in real life situations thus is a good measure of decision making. role working memory (WM) IGT performance still remains unclear. present study aimed to examine the effect WM on performance. Three groups participants matched gender ratio were randomly assigned no load, low high load conditions. Initially three did not show significant difference capacity. They finished modified version then their implicit learning explicit...

The beneficial effects of Lactobacillus probiotics in animal production are often strain-related. Different strains from the same species may exert different weight-gain effect on hosts vivo. Most lactobacilli selected based their vitro activities, and metabolism regulation intestine strain-related characters largely unexplored. objective present study was to vivo three growth performance compare differential faecal microbiota ileum mucosa proteomics piglets. Three hundred sixty piglets were...

A facile and efficient nickel-catalyzed C-C bond cleavage/phosphorylation of various cycloalkyl hydroperoxides was developed. This radical ring-opening strategy provided practical access to structurally diverse distal ketophosphine oxides in one pot through concurrent C═O/C-P formation with high atom economy under mild room temperature base-free conditions.

Prospective memory (PM) refers to remembering do something at a future time. Studies have shown that implementation intention can improve PM performance. The present study aimed examine the effect and mechanism of on in individuals prone for schizotypal personality disorder (SPD proneness) laboratory condition. A total 51 participants with SPD proneness controls were administered task. They further randomly assigned an condition typical instruction All completed task low high cognitive load...

Peer relations during adolescence contribute significantly to the development of socio-cognitive skills and pro-sociality. The current study probed characteristics adolescent processing through a card game where they earn money for self friend. We investigated choice preference temporal dynamics information by measuring ERP responses wins or losses (valence) directed toward friend (recipient). Choice data showed that despite adults adolescents earning equivalent amounts across recipients...

As an important part of track inspection, the detection rail fasteners is great significance to improve safety train operation. Additionally, fastener belongs small-target detection. The YOLOv4 algorithm relatively fast in and has some advantages Therefore, used for status However, still suffers from following two problems First, features extracted by original feature extraction network are rough, which not conducive crack anomaly on fasteners. In addition, traditional convolutional neural a...

Twenty-four weanling barrows were fed corn-soybean diets supplemented with 2% conjugated linolenic acid (CLA) or soybean oil. On day 14 and 21, pigs injected intraperitoneally lipopolysaccharide (LPS) sterile saline. Plasma samples collected 2h after injection. Peripheral blood mononuclear cells (PBMC) also on 2 h injection to determine tumor necrosis factor-alpha (TNF-alpha) production its mRNA expression. The results indicate that dietary CLA inhibited the of TNF-alpha by pig PBMC both at...

Prospective memory (PM) refers to the ability remember carry out intended actions after a delay. PM impairments are common in schizophrenia patients and thought be related their prefrontal cortex dysfunction; however, this has not yet been examined directly research literature. The current study aimed examine abnormalities brain activation during task performance patients.Twenty-two 25 matched healthy controls were scanned 3-T MRI machine while performing task.The results showed that...

Mental time travel refers to the ability recall episodic past and imagine future events. The present study aimed investigate cultural differences in mental between Chinese Australian university students. A total of 231 students (108 & 123 Australians) participated study. Their abilities were measured by Sentence Completion for Events from Past Test (SCEPT) Future (SCEFT). Results showed that there no number specific events generated or future. Significant participants found mainly emotional...

This paper aims to create a prediction model for car body vibration acceleration that is reliable, effective, and close real-world conditions. Therefore, huge amount of data on railway parameters were collected by multiple sensors, different correlation coefficients selected screen out the closely correlated acceleration. Taking previous as inputs, was established based several training algorithms neural network structures. Then, successfully applied predict test datasets segments same...
