Currently, only a few states in the USA (e.g., Colorado and Ohio) require mandatory baseline groundwater sampling from nearby groundwater wells prior to drilling a new oil or gas well. Colorado is the first state to regulate groundwater testing before and after drilling, which requires one pre-drilling sample and two additional post-drilling samples within 6-12 months and 5-6 years of drilling. However, the monitoring method is limited to the state's regulatory agency and to ex situ sampling, which offers only a snapshot in time...

Functional (psychogenic) tremor is the most common functional movement disorder. Characteristic clinical features, so called red flags, can help to make the clinical distinction of this type from other tremor disorders. The most common features include the variability of frequency and amplitude. Clinical examination should include different types of distraction including motor or cognitive tasks or testing the influence of suggestibility on tremor amplitude, frequency or direction. Patients often report sudden onset and remissions that may last for months or even years...

When an action produces an effect, the effect is perceived earlier in time compared to a stimulus without preceding action. This temporal bias is called intentional binding (IB) and serves as an implicit measure of sense of agency. Typically, IB is investigated by presenting a rotating clock hand while participants execute an action and perceive a resulting tone. Participants are asked to estimate the time point of tone onset by referring to the clock hand position. This time point estimate is compared to a time point estimate of a tone in a condition in which the tone occurs without preceding action...

Academia-intelligence agency collaborations are on the rise for a variety of reasons. These can take many forms, one of which is in the classroom, using students to stand in for intelligence analysts. Classrooms, however, are ethically complex spaces, with students considered vulnerable populations, and become even more complex when layering multiple goals, activities, tools, and stakeholders over those traditionally present. This does not necessarily mean one must shy away from academia-intelligence agency partnerships in classrooms, but that these must be conducted carefully and reflexively...

Embodiment and agency are key aspects of how we perceive ourselves that have typically been associated with independent mechanisms. Recent work, however, has suggested that these mechanisms are related. The sense of agency arises from recognising a causal influence on the external world. This influence is typically realised through bodily movements and thus the perception of the bodily self could also be crucial for agency. We investigated whether a key index of agency - intentional binding - was modulated by body-specific information...

BACKGROUND: In sub-Saharan Africa, there is growing interest in the use of cash transfer (CT) programs for HIV treatment and prevention. However, there is limited evidence of the consequences related to CT provision to adolescents in low-resourced urban settings. We explored the experiences of adolescents receiving CTs to assess the acceptability and unintended consequences of CT strategies in urban Johannesburg, South Africa. METHODS: We collected qualitative data during a pilot randomized controlled trial of three CT strategies (monthly payments unconditional vs...

BACKGROUND: Studies on hospital violence have emphasized the importance of staff- service recipient interaction in leading to violent incidents. These incidents are the extreme result of service recipients' frustration and anger in their interaction with staff. The aim of this study was to analyze factors related to negative experiences of emergency department (ED) patients and accompanying persons in Israeli hospitals. METHODS: Structured interviews with 692 participants in seven major general Israeli hospitals: 322 patients and 370 accompanying persons...

Importance: The US Environmental Protection Agency is required to reexamine its National Ambient Air Quality Standards (NAAQS) every 5 years, but evidence of mortality risk is lacking at air pollution levels below the current daily NAAQS in unmonitored areas and for sensitive subgroups. Objective: To estimate the association between short-term exposures to ambient fine particulate matter (PM2.5) and ozone, and at levels below the current daily NAAQS, and mortality in the continental United States...

OBJECTIVE: Dystonia is a movement disorder that has been associated with impaired motor learning and sequence recognition. However, despite evidence that patients with dystonia have a reduced sense of agency, it is unclear whether dystonia is specifically associated with impaired recognition of a movement sequence. We have shown previously that performance consistency in the temporal and kinematic domains predicts awareness of underlying motor patterns in a finger tapping task. Because movements in dystonia are characterized by high variability, we predicted that subjects with dystonia would have decreased motor sequence awareness...

Cancer is one of the most serious illnesses of our civilization. The International Agency for Research on Cancer estimated that 14.1 million new cancer cases were diagnosed. Therefore, the cure efficiency of cancer chemotherapy depends not only on how the anticancer drug is delivered to its targets but also on the anticancer drug itself. Among the approved drugs 80% are derived from natural compounds. In this sense, coumarins, natural polyphenols for which anticancer activity has been proved, can be a source or inspire the synthesis of new anticancer agents...

President Donald J. Trump has said he will repeal the Affordable Care Act (ACA) and replace it with health savings accounts (HSAs). Conservatives have long preferred individual accounts to meet social welfare needs instead of more traditional entitlement programs. The types of "medical care" that can be reimbursed through an HSA are listed in section 213(d) of the Internal Revenue Code (Code) and include expenses "for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body...

BACKGROUND: A violent 'war on drugs' continues to be waged in the Philippines, even as the use of drugs - particular methamphetamine - continues to rise. Furnishing contextual background to the current situation, this paper explores how long-running law enforcement approaches in the Philippines might be viewed by those in their receiving end by presenting findings of an ethnography among marginalized young men. METHODS: Semi-structured interviews and focus group discussions were conducted among 20 young men throughout a 12-month period of participant-observation from December 2011 to September 2013...

The layered materials like transition metal dichalcogenides exhibit broad spectra of outstanding properties with huge application potential, while another group of related materials, layered transition metal trichalcogenides remains unexplored. Here we show a broad application potential of this interesting structural type of layered tantalum trisulfide prepared in a form of nanofibers. This material shows tailorable attractive electronic properties dependent on the tensile strain applied to it. Structure of this so-called orthorhombic phase of TaS3 grown in a form of long nanofibers has been solved and refined...

N Karsh, O Goldstein, B Eitam
Pain is an integral part of our lives. Although the effect of 'control' on sensed pain has been extensively studied and discussed, recent findings seem to be at odds with the substantial evidence for a robust motor-based sensory attenuation effect - an indirect marker for one's sense of agency. The goal of the current study was to re-examine whether there is evidence for such an effect in the context of pain. In three experiments, human participants were aversively stimulated and the sensitivity of self-reported pain to factors previously shown to modulate the sensory attenuation effect was tested (control over parameters of the stimulation; temporal contiguity and predictability, and stimulation intensity)...

Liang Luo, Ting Song, Haoqiang Wang, Qunhui Yuan, Shenghai Zhou
Inspired by low toxicity and good biocompatibility of biomass derived quantum dot (QD), we herein developed a cytosine derived quantum dot, namely cyt-dot, via a one-step hydrothermal synthesis. The as-prepared cyt-dot emits blue fluorescence (FL) containing abundant oxygen (20.6at.%) and nitrogen (24.1at.%) contents. The cyt-dot based sensing platform shows exclusive selectivity for Hg(II) while being insensitive towards Fe(III) and Ag(I), which are important interference that usually cannot be ruled out. The detection limit for Hg(II) is of 11nM, which is very close to the guideline value of 10nM allowed by the U...

REVIEW
Davide Crivelli, Michela Balconi
According to philosophy of mind and neuroscientific models, the sense of agency can be defined as the sense that I am the one that is generating an action and causing its effects. Such ability to sense ourselves as causal agents is critical for the definition of intentional behavior and is a primary root for human interaction skills. The present mini-review aims at discussing evidences from non-invasive brain stimulation (NIBS) studies targeting functional correlates of different aspects of agency and evidences on the way stimulation techniques affect such core feature of human subjective experience...

In order to increase the cost-efficiency, availability and ease of accessing and delivering mindfulness-based interventions (MBIs), clinical and research interest in mindfulness-based self-help (MBSH) interventions has increased in recent years. Several studies have shown promising results of effectiveness of MBSH. However, like all self-help interventions, dropout rates and disengagement from MBSH are high. The current study explored the facilitators and barriers of engaging in a MBSH intervention. Semi-structured interviews with members of healthcare staff who took part in an MBSH intervention (n = 16) were conducted...
