#1
Peng Liu, Run Yang, Zhigang Xu
Self-driving vehicles (SDVs) promise to considerably reduce traffic crashes. One pressing concern facing the public, automakers, and governments is "How safe is safe enough for SDVs?" To answer this question, a new expressed-preference approach was proposed for the first time to determine the socially acceptable risk of SDVs. In our between-subject survey (N = 499), we determined the respondents' risk-acceptance rate of scenarios with varying traffic-risk frequencies to examine the logarithmic relationships between the traffic-risk frequency and risk-acceptance rate...

James McLeod, Z Othman, Rajarathinam Parthasarathy
The relationship between mixing energy input and biogas production was investigated by anaerobically digesting sewage sludge in lab scale, hydraulically mixed, batch mode digesters at six different specific energy inputs. The goal was to identify how mixing energy influenced digestion performance at quantitative levels to help explain the varying results in other published works. The results showed that digester homogeneity was largely uninfluenced by energy input, whereas cumulative biogas production and solids destruction were...

REVIEW
Francesco Lupariello, Serena Curti, Janet Barber Duval, Giovanni Abbattista, Giancarlo Di Vella
Geberth in 2006 stated that "staging is a conscious criminal action on the part of an offender to thwart an investigation." In the present paper two crime scenes staged by handling digital evidence are reported. The first case involves a 50-year-old woman who had been living with the offender for three years before he murdered her at the end of their relationship. He staged the scene as a sex-related crime committed by an unknown perpetrator. The second case concerns a young woman who was found dead in Southern Italy in January 2004 with a gunshot on the forehead...

Alterations in peripheral immune markers are observed in individuals with post-traumatic stress disorder (PTSD). PTSD is characterized in part by impaired extinction of fear memory for a traumatic experience. We hypothesized that fear memory extinction is regulated by immune signaling stimulated when fear memory is retrieved. The relationship between fear memory and the peripheral immune response was tested using auditory Pavlovian fear conditioning in mice. Memory for the association was quantified by the amount of conditioned freezing exhibited in response to the conditioned stimulus (CS), extinction and time-dependent changes in circulating inflammatory cytokines...

INTRODUCTION: Sleepiness and cardiovascular disease share common molecular pathways; thus, genetic risk factors for sleepiness may also predict cardiovascular disease risk. This study explored the associations between subjective sleepiness and single-nucleotide polymorphisms (SNPs) in candidate genes within oxidative stress, inflammatory, and neuronal pathways, which may contribute to sleepiness and downstream cardiovascular disease risk: Cytochrome B-245, Alpha Polypeptide (CYBA), Cytochrome B-245, Beta Polypeptide (CYBB), Neutrophil Cytosolic Factor (NCF2), Tumor Necrosis Factor-Alpha (TNFA), and Phosphodiesterase 4D (PDE4D)...

OBJECTIVE: Children's sleep problems are associated with poorer student functioning in the school environment, including impairment in peer relationships; yet, no studies have examined sleep functioning in relation to the student-teacher relationship. The objective of this study was to examine whether child-rated total sleep problems or specific sleep problem domains (bedtime problems, nighttime problems, or daytime sleepiness) were associated with teacher-rated student-teacher closeness and conflict after controlling for student mental health symptoms known to be associated with both greater sleep problems and poorer student-teacher relationship quality...

The ability to view biological events in real time has contributed significantly to research in the life sciences. While video capture of real time changes in anatomical relationships is important, it is equally important to visualize real time changes in the chemical communications that drive cell behaviors. This paper describes an electrochemical imaging system capable of capturing changes in chemical gradients in live tissue slices. The system consists of a CMOS microchip with 8192 configurable Pt surface electrodes, on-chip potentiostat, on-chip control logic, and a microfluidic device designed to interface with the CMOS chip to support ex vivo tissue experimentation...

The purpose of this study was to investigate whether death anxiety is more closely linked with optimism or pessimism among older adults. Participants consisted of community-dwelling older adults (N = 253; 73.1% female) in the southern U.S. Both optimism and pessimism demonstrated a bivariate association with death anxiety; however, when considering optimism and pessimism together-and after controlling for age, gender, physical health, and mental health-optimism was not associated with death anxiety, while pessimism was associated with higher death anxiety...

Little is known about the association between school climate and adolescent relationship abuse (ARA). We used 2011-2012 data from surveys of California public school students (in the United States of America) who were in a dating relationship in the last year (n = 112 378) to quantify the association between different school climate constructs and physical ARA. Fifty-two percent of students were female, and all students were in 9th or 11th grade (approximately ages 14-17). Over 11% of students reported experiencing physical ARA in the last year...

Higher sleep spindle activity generally relates to better cognitive performance in adults, while studies in children often show the opposite. As children become young adults, there is rapid brain maturation and development of higher-order cognitive functions, and therefore investigations within this age group may elucidate the relationship between spindles and cognition in this developmental period. Twelve studies published between 2009 and 2016 were identified. Meta-analyses revealed a positive relationship between spindles and cognition overall (r = 0...

BACKGROUND: Collaboration among healthcare providers has been considered a promising strategy for improving care quality and patient outcomes. Despite mounting evidence demonstrating the impact of collaboration on outcomes of healthcare providers, there is little empirical evidence on the relationship between collaboration and patient safety outcomes, particularly at the patient care unit level. OBJECTIVES: The purpose of this study is to identify the extent to which interdisciplinary collaboration between nurses and physicians and intradisciplinary collaboration among nurses on patient care units are associated with patient safety outcomes...

Neuroimaging studies have identified that anhedonia, a core feature of major depressive disorder (MDD), is associated with dysfunction in reward and cognitive control processing. However, it is still not clear how the reward network (β-network) and the cognitive control network (δ-network) are linked to biased anhedonia in MDD patients. Sixty-eight MDD patients and 64 cognitively normal (CN) subjects underwent a resting-state functional magnetic resonance imaging scan. A 2*2 ANCOVA analysis was used to explore the differences in the nucleus accumbens-based, voxelwise functional connectivity (FC) between the groups...

The Yangtze River delta white goat is the only goat breed that produces high-quality brush hair, which is specifically used in top-grade writing brushes. Previous studies have indicated that the CMTM3 and DUSP1 genes are involved in the growth and cycle of high-quality brush hair, and these genes are thought to be involved in the formation of high-quality brush hair traits. In this study, we investigated the relationship between methylation of CMTM3 and DUSP1 and such traits. The results indicated that the relative expression levels of the CMTM3 and DUSP1 genes were higher in non-high-quality brush hair than in high-quality brush hair...

BACKGROUND: Although the Star Excursion Balance test (SEBT) has shown a good intra-session reliability the inter-session reliability of this test has not been deeply studied. Furthermore, there is an evident high influence of the lower-limbs in the performance of the SEBT so even if it has been used to measure core stability it is possibly not the most suitable measurement. OBJECTIVE: The aims of this study were: i) to assess the absolute and relative between-session reliability of the SEBT and two novel variations of this test to assess trunk postural control while sitting, i...
