How useful can machine learning be in a quantum laboratory? Here we raise the question of the potential of intelligent machines in the context of scientific research. A major motivation for the present work is the unknown reachability of various entanglement classes in quantum experiments. We investigate this question by using the projective simulation model, a physics-oriented approach to artificial intelligence. In our approach, the projective simulation system is challenged to design complex photonic quantum experiments that produce high-dimensional entangled multiphoton states, which are of high interest in modern quantum experiments...

BACKGROUND: Roles in the doctor-patient relationship are changing and patient participation in health care is increasingly emphasized. Electronic health (eHealth) services such as patient accessible electronic health records (PAEHRs) have been implemented to support patient participation. Little is known about practical use of PAEHR and its effect on roles of doctors and patients. OBJECTIVE: This qualitative study aimed to investigate how physicians view the idea of patient participation, in particular in relation to the PAEHR system...

Challenge: Trainees' motivational and emotional states can influence their learning and career decisions, but historically these "affective" learning factors have received little attention in medical education. In this "Tips" piece, we outline strategies to positively influence trainees' intrinsic motivation and emotion toward their training to ultimately enhance their overall learning experience.

Extreme overvalued beliefs (EOB) are rigidly held, non-deusional beliefs that are the motive behind most acts of terrorism and mass shootings. EOBs are differentiated from delusions and obsessions. The concept of an overvalued idea was first described by Wernicke and later applied to terrorism by McHugh. Our group of forensic psychiatrists (Rahman, Resnick, Harry) refined the definition as an aid in the differential diagnosis seen in acts of violence. The form and content of EOBs is discussed as well as group effects, conformity, and obedience to authority...

This paper proposes a combined Virtual Reference Feedback Tuning-Q-learning model-free control approach, which tunes nonlinear static state feedback controllers to achieve output model reference tracking in an optimal control framework. The novel iterative Batch Fitted Q-learning strategy uses two neural networks to represent the value function (critic) and the controller (actor), and it is referred to as a mixed Virtual Reference Feedback Tuning-Batch Fitted Q-learning approach. Learning convergence of the Q-learning schemes generally depends, among other settings, on the efficient exploration of the state-action space...

The introduction of living invertebrates into the classroom was investigated. First, possible anchor points for a lesson with living invertebrates are explored by referring to the curriculum of primary/secondary schools and to out-of-school learning. The effectiveness of living animals for increasing interest, motivation, and achievement in recent research is discussed. Next, the Vivarium, an out-of-school learning facility with living invertebrates, is described. The effects of an intervention study with living invertebrates on achievement are then investigated at school (School condition) and out of school (University condition); a third group served as a control condition...

A few weeks ago, Texas took an unprecedented position on unilateral DNRs by passing Senate Bill (SB) 11, which requires patient/surrogate consent for writing DNR orders. The motivation behind the bill was based on the drafters' beliefs that physicians frequently write unilateral DNR orders. SB 11, however, does not stop at requiring physicians to seek consent for DNR orders. Instead, the legislation uncharacteristically exceeds what is typically within the scope and role boundaries for lawmakers by legislating how physicians discuss and implement DNR orders...

INTRODUCTION: The WHO Regional Office for Europe developed the Guide to tailoring immunization programmes (TIP), offering countries a process through which to diagnose barriers and motivators to vaccination in susceptible low vaccination coverage and design tailored interventions. A review of TIP implementation was conducted in the European Region. MATERIAL AND METHODS: The review was conducted during June to December 2016 by an external review committee and was based on visits in Bulgaria, Lithuania, Sweden and the United Kingdom that had conducted a TIP project; review of national and regional TIP documents and an online survey of the Member States in the WHO European Region that had not conducted a TIP project...

Acetylcholine (ACh) signaling shapes neuronal circuit development and underlies specific aspects of cognitive functions and behaviors, including attention, learning, memory and motivation. During behavior, activation of muscarinic and nicotinic acetylcholine receptors (mAChRs and nAChRs) by ACh alters the activation state of neurons, and neuronal circuits most likely process information differently with elevated levels of ACh. In several brain regions, ACh has been shown to alter synaptic strength as well. By changing the rules for synaptic plasticity, ACh can have prolonged effects on and rearrange connectivity between neurons that outlasts its presence...

Substance use (e.g., alcohol, marijuana, opioids, cocaine., etc,) use often initiates during adolescence, a critical period of physiological and social development marked by an increase in risk-taking due, in part, to heightened motivation to obtain arousal from rewards. Substance use during adolescence has been associated with a greater risk of substance use disorders (SUD) in adulthood. Although use rates for most substances have remained relatively stable, the frequency of marijuana use and the perception that regular marijuana use is not harmful has increased in adolescents...

BACKGROUND AND OBJECTIVE: The Accident and Emergency Department (A&ED) is the frontline for providing emergency care in hospitals. Unfortunately, relative A&ED resources have failed to keep up with continuously increasing demand in recent years, which leads to overcrowding in A&ED. Knowing the fluctuation of patient arrival volume in advance is a significant premise to relieve this pressure. Based on this motivation, the objective of this study is to explore an integrated framework with high accuracy for predicting A&ED patient flow under different triage levels, by combining a novel feature selection process with deep neural networks...

An important aspect of perspective-taking ability is the appreciation that mental states such as beliefs, desires, and knowledge change over time. The current study focused specifically on 3-, 4-, and 5-year-olds' understanding that they will have knowledge in the future that they do not currently possess-for example, that when they are grown-ups, they will know what the words on a newspaper say. We also compared this understanding to children's understanding that adults have knowledge that children do not...

The significant increase in the incidence rates and ongoing outbreaks of serogroup C meningococcal (MenC) disease, associated with the sequence type-103 complex, motivated the incorporation of the meningococcal C conjugate (MCC) vaccine in the routine immunization program in the State of Bahia, Brazil in early 2010, targeting children younger than 5 years of age. In its capital, Salvador, the program also included a catch-up campaign for individuals 10-24 years of age. We performed an observational, ecological study, analyzing data collected from 2007 to 2015, to compare the impact of these two immunization strategies on meningococcal disease incidence and mortality rates...

OBJECTIVE: To examine how first-time fathers in rural Tasmania experienced father-only antenatal support/education groups. DESIGN: Semistructured interviews with expectant fathers were used for this study. Purposive sampling was used to recruit fathers in 2014. Participants were recruited face-to-face via email through a government health service and not-for-profit organisation that runs a state-wide fatherhood program. Several participants were recruited through a company that holds antenatal education classes for men in a pub...

BACKGROUND: College of nursing leaders can foster organizational learning as a means of achieving their desired organizational outcomes. Organizational learning has not previously been studied in colleges of nursing, leaving college administrators and faculty little guidance as they strive to improve outcomes in their own colleges. OBJECTIVES: The purpose of this study was to discover new insights related to organizational learning in a college of nursing. DESIGN: The learning history method was used to document and describe organizational learning in a college of nursing...

A three-dimensional (3-D) convolutional neural network (CNN) trained from scratch is presented for the classification of pulmonary nodule malignancy from low-dose chest CT scans. Recent approval of lung cancer screening in the United States provides motivation for determining the likelihood of malignancy of pulmonary nodules from the initial CT scan finding to minimize the number of follow-up actions. Classifier ensembles of different combinations of the 3-D CNN and traditional machine learning models based on handcrafted 3-D image features are also explored...

Contemporary theories of learning emphasize the role of a prediction error signal in driving learning, but the nature of this signal remains hotly debated. Here, we used Pavlovian conditioning in rats to investigate whether primary motivational and emotional states interact to control prediction error. We initially generated cues that positively or negatively predicted an appetitive food outcome. We then assessed how these cues modulated aversive conditioning when a novel cue was paired with a foot shock. We found that a positive predictor of food enhances, whereas a negative predictor of that same food impairs, aversive conditioning...

BACKGROUND: Web-based mental health interventions have evolved from innovative prototypes to evidence-based and clinically applied solutions for mental diseases such as depression and anxiety. Open-access, self-guided types of these solutions hold the promise of reaching and treating a large population at a reasonable cost. However, a considerable factor that currently hinders the effectiveness of these self-guided Web-based interventions is the high level of nonadherence. The absence of a human caregiver apparently has a negative effect on user adherence...

Teaching non-human primates the complex cognitive behavioral tasks that are central to cognitive neuroscience research is an essential and challenging endeavor. It is crucial for the scientific success that the animals learn to interpret the often complex task rules, and reliably and enduringly act accordingly. To achieve consistent behavior and comparable learning histories across animals, it is desirable to standardize training protocols. Automatizing the training can significantly reduce the time invested by the person training the animal...

Despite strong support for inclusive education in principle, many teachers and administrators still demonstrate mixed responses to the inclusion of certain students in their classrooms. Students with specific learning difficulties (SpLD) form a large group of students in inclusive classrooms yet some provincial, state and national jurisdictions fail to acknowledge the existence of these students. Not acknowledging and understanding these students can deny them the recognition and resources necessary for their genuine participation in education and, in turn, society...
