Tactile sensing is of great importance in developing human-machine interface, remote control and security systems. Here, a self-triggered alarm system based on the one-piece triboelectric nanosensor (TENS) is reported. By using nitrocellulose (NC) membrane as the triboelectric material, the as-designed TENS can not only sensitively respond to physical contacts in a self-triggered mode, but also securely detect the third-level details of latent fingerprint. The self-triggered idea based on the triboelectric nanogenerator is compatible with intelligent interactive interface...

A new type of responsive battery with the fascinating feature of pressure perceptibility has been developed, which can spontaneously, timely and reliably control the power outputs (e.g., current and voltage) in response to pressure changes. The device design is based on the structure of the Zn-air battery, in which graphene-coated sponge serves as pressure-sensitive air cathode that endows the whole system with the capability of self-controlled energy release. The responsive batteries exhibit superior battery performance with high open-circuit voltage (1...

This study reports findings from the administration of a social problem-solving training (SPST) intervention to juvenile detainees in the Connecticut Youth Detainee Program. SPST is a cognitive behavioral intervention that teaches children and youth how to more effectively cope with interpersonal stress and conflict. In the current study, we tested whether SPST could decrease depressive symptoms in a sample of detained adolescent offenders. The study used a randomized-control design with detention staff administering the intervention...

We report a new nucleic acid sensing strategy through an intelligent design of spatial organization based reciprocal switching of catalytic hairpin assembly (CHA). The so-called SORS-CHA not only turns a well-designed CHA circuit into a relatively universal detector for any targeting sequence, but also guarantees a much enhanced signal resolution and a believability to minimize the misreading induced by unexpected signal drifts. With more trustworthy results, but a simpler sequence design, nucleic acid circuits could become competitive in real-world applications...

Although working memory (WM) training programs consistently result in improvement on the trained task, benefit is typically short-lived and extends only to tasks very similar to the trained task (i.e., near transfer). It is possible that pairing repeated performance of a WM task with brain stimulation encourages plasticity in brain networks involved in WM task performance, thereby improving the training benefit. In the current study, transcranial direct current stimulation (tDCS) was paired with performance of a WM task (n-back)...

In this review, we summarize the recent progress made in the fabrication of pure natural materials such as biogenic capsules. Unlike polyelectrolyte capsules, biogenic capsules are primarily prepared with pure natural components using layer-by-layer (LbL) assembly on sacrificial templates. These capsules have been developed as smart materials for guest molecule encapsulation and delivery in the last two decades. With the extreme demands on biodegradability and biocompatibility, biogenic capsules exhibit unique properties that can be integrated with special ligands or conjugated functional groups for the design of intelligent platforms, significantly enriching their functions and applications...

Despite having the basic tools necessary to appropriately identify and manage individuals with hypertension for over half a century it remains the single greatest contributing risk factor to morbidity and mortality worldwide today. Since diagnosis and effective treatment availability are not issues, this major failing in care can be attributed to inadequate systems of care: systems that have led to only <20% of hypertensive individuals globally having their blood pressure adequately controlled. Even in the US, where it is one of the most common reasons for a primary care visit, and with over $42...

BACKGROUND: Glycol ethers (GE) are widely used organic solvents. Despite the potential neurotoxicity of several families of organic solvents, little is known about the impact of GE on the neurodevelopment of infants and children. OBJECTIVES: We investigated the relation between urinary concentrations of GE metabolites in pregnant women and neurocognitive abilities in their 6-year-old children in the PELAGIE mother-child cohort. METHODS: Five GE metabolites were measured in first-void urine samples of 204 French pregnant women in early pregnancy (<19 weeks of gestation)...

Incubating in the rise of the perovskite photovoltaic era, an intelligent material design allows now for a fine tune of the properties, targeting also light-emitting applications. Herein benefits derive from the use of low dimensional and nanostructured perovskites, marginally exploited in photovoltaic devices, allowing for exciton engineering and for intrinsic resonating structures. By evaluating halide perovskites, envisioning light-emitting applications, particular attention is dedicated to the role that this material can effectively play in the field...

Well-designed and well-conducted clinical studies represent gold standard approaches for generating medical evidence. However, elderly populations are systematically underrepresented in studies across major chronic medical conditions, which has hampered the generalizability (external validity) of studies to the real-world patient population. It is the norm that intervention studies often require a homogeneous cohort to test their hypotheses; therefore older adults with co-medications and comorbidities are often excluded...

At the beginning of preschool (M = 46 months of age), 197 (94 boys) children were administered tasks that assessed a suite of nonsymbolic and symbolic quantitative competencies as well as their executive functions, verbal and nonverbal intelligence, preliteracy skills, and their parents' education level. The children's mathematics achievement was assessed at the end of preschool (M = 64 months). We used a series of Bayesian and standard regression analyses to winnow this broad set of competencies down to the core subset of quantitative skills that predict later mathematics achievement, controlling other factors...

In this Letter, the authors describe the characterisation design and development of the authors' wearable, multimodal vitals acquisition unit for intelligent field triage. The unit is able to record the standard electrocardiogram, blood oxygen and body temperature parameters and also has the unique capability to record up to eight custom designed acoustic streams for heart and lung sound auscultation. These acquisition channels are highly synchronised to fully maintain the time correlation of the signals. The unit is a key component enabling systematic and intelligent field triage to continuously acquire vital patient information...

Continuous patient monitoring systems acquire enormous amounts of data that is either manually analysed by doctors or automatically processed using intelligent algorithms. Sections of data acquired over long period of time can be corrupted with artefacts due to patient movement, sensor placement and interference from other sources. Owing to the large volume of data these artefacts need to be automatically identified so that the analysis systems and doctors are aware of them while making medical diagnosis. Three important factors are explored that must be considered and quantified for the design and evaluation of automatic artefact identification algorithms: signal quality, interpretation quality and computational complexity...

A novel bis[alkynylplatinum(ii)] terpyridine molecular tweezer with conformationally-rigid spacer has been designed and synthesized, which shows enhanced binding affinity towards the complementary guests when compared to its semi-rigid counterpart. Moreover, a three-component supramolecular recognition system comprised of the molecular tweezer and two electron-rich guests was established. Reversible switching of the host-guest binding preference can be achieved via adding a trace amount of hexafluoroisopropanol (HFIP) into chloroform...

To treat a worldwide common ear disease (OME), a device allowing fast grommet tube insertion has been designed in our earlier works (Gao et al., 2015 [1] and Liang et al., 2013 [2]). However, the instrument has to be manually placed as close as to the Tympanic Membrane before the insertion procedures. To realize a fully automated surgical process, the instrument shall be automatically manipulated to align to the axial direction of ear canal and proceed to complete the surgery. A vision-based servomechanism is proposed to solve the path planning problem...

The harm of Salmonella typhimurium (S. typhimurium) to public health mainly by the consumption of contaminated agricultural products or water stresses an urgent need for rapid detection methods to help control the spread of S. typhimurium. In this work, an intelligently designed sensor system took creative advantage of triple trigger sequences-regenerated strand displacement amplification and self-protective hairpin template-generated-scaffolded silver nanoclusters (AgNCs) for the first time. In the presence of live S...

In this case series (n = 10) with a non-concurrent multiple baseline design, a self-management program was shown to be effective during inpatient training in eight participants with oral-motor problems and normal intelligence or mild intellectual disabilities. They were taught to perform a self-management routine and to remain dry for increasing time intervals. In addition, the program provided differential (self-) reinforcement of swallowing, controlling and wiping behavior, explicit formulation of motivational factors, instruction and feedback for parents and teachers, and continued practice after discharge...

BACKGROUND: It has been well established that child physical abuse is a risk factor for cognitive deficits and behavioral problems. However, the possible link between cognitive deficits and behavioral problems placing children at a higher risk of physical abuse has been overlooked. Using a prospective design, the present study aims to examine whether previously measured cognition indicated by intelligence quotient (IQ), including performance IQ (PIQ) and verbal IQ (VIQ), and behavioral problems reported by multiple informants (i...
