Dear Abby: Should I Give Advice or Receive It?

Typically, individuals struggling with goal achievement seek advice. However, in the present investigation ( N = 2,274), struggling individuals were more motivated by giving advice than receiving it. In a randomized, controlled, double-blind field experiment, middle-school students who gave motivational advice to younger students spent more time on homework over the following month than students who received motivational advice from expert teachers (Experiment 1). This phenomenon was replicated across self-...


Motivation for physical activity and the moderating effect of cancer diagnosis: A nationally representative cross-sectional study.

The aim of this study was to investigate associations between types of motivation for physical activity and self-reported weekly aerobic moderate-to-vigorous physical activity (MVPA) in the 2012 and 2014 waves of the nationally representative Health Information National Trends Survey 4 (n = 7307). We further explored differential associations between MVPA and types of motivation for physical activity by cancer survivor status. We found that those who were more motivated by "getting enjoyment from exerci...

Electron single flexural phonon relaxation, energy loss and thermopower in single and bilayer graphene in the Bloch-Gruneisen regime.

The flexural phonons serve as one of the important modes of interaction in graphene that can inhibit carrier mobility. For the estimation of scattering due to flexural phonons a two-phonon scattering process had been in place, as due to symmetry constraints out-of-plane deformations modulate electron hopping only in the second order. But recently it has been shown that electrostatic gating can break the planar mirror symmetry and activate single flexural phonon scattering processes (Gunst et al 2017 Phys. R...


Learning to see the threat: temporal dynamics of ERPs of motivated attention in fear conditioning.

Social threat detection is important in everyday life. Studies of cortical activity have shown that event-related potentials (ERPs) of motivated attention are modulated during fear conditioning. The time course of motivated attention in learning and extinction of fear is however still largely unknown. We aimed to study temporal dynamics of learning processes in classical fear conditioning to social cues (neutral faces) by selecting an experimental setup that produces large effects on well-studied ERP compon...

How Do We Know when Single-Molecule Force Spectroscopy Really Tests Single Bonds?

Single-molecule force spectroscopy makes it possible to measure the mechanical strength of single noncovalent receptor-ligand-type bonds. A major challenge in this technique is to ensure that measurements reflect bonds between single biomolecules because the molecules cannot be directly observed. This perspective evaluates different methodologies for identifying and reducing the contribution of multiple molecule interactions to single-molecule measurements to help the reader design experiments or assess pub...

Photophysical Pathways in Highly Sensitive CsAgBiBr Double-Perovskite Single-Crystal X-Ray Detectors.

The sensitive detection of X-rays embodies an important research area, being motivated by a common desire to minimize the radiation doses required for detection. Among metal halide perovskites, the double-perovskite CsAgBiBr system has emerged as a promising candidate for the detection of X-rays, capable of high X-ray stability and sensitivity (105 μC Gy cm). Herein, the important photophysical pathways in single-crystal CsAgBiBr are detailed at both room (RT) and liquid-nitrogen (LNT) temperatures, with e...

Electrochemistry of Single Enzymes: Fluctuations of Catalase Activities.

Dynamic fluctuations of the catalytic ability of single catalase enzymes towards hydrogen peroxide decomposition are observed via the nano-impact technique. The electrochemical signals of single enzymes show that the catalytic ability of single enzymes can temporarily be much higher than expected from the classical, time-averaged Michaelis-Menten description. By combination of experimental data with a new theoretical model, we interpret the unusual enhancement of the single catalase signal and find that sin...

Sexual behaviour of the female rat during late adolescence: effect of chronic cocaine treatment.

Sexual behaviour is highly motivated and female rats begin to express it during adolescence. The circuitries implicated in the control of motivated behaviours continue to mature during adolescence and seem more sensitive to the effects of psychostimulants such as cocaine. However, a putative differential effect of this drug on the sexual behaviour of females according to age has not yet been studied. Therefore, we compared the motivational value of a male and the expression of sexual behaviour of late-adole...

Hypocretin as a Hub for Arousal and Motivation.

The lateral hypothalamus is comprised of a heterogeneous mix of neurons that serve to integrate and regulate sleep, feeding, stress, energy balance, reward, and motivated behavior. Within these populations, the hypocretin/orexin neurons are among the most well studied. Here, we provide an overview on how these neurons act as a central hub integrating sensory and physiological information to tune arousal and motivated behavior accordingly. We give special attention to their role in sleep-wake states and cond...

Close or far? Affect explains conflicting findings on motivated distance perception to rewards.

Research on motivated perception has yielded conflicting findings: Whereas Balcetis and Dunning (2010) showed that people approaching (vs. avoiding) rewarding objects (e.g. food) see them as closer, Krpan and Schnall (2014a) found the opposite. Furthermore, whereas Balcetis (2016) suggested that people who perceive rewarding objects as closer (vs. farther) should subsequently consume more, Krpan and Schnall (2017) showed that they actually ate less. We introduce affect as the missing link to explain these c...

Monostable multivibrators as novel artificial neurons.

Retriggerable and non-retriggerable monostable multivibrators are simple timers with a single characteristic, their period. Motivated by the fact that monostable multivibrators are implementable in large quantities as counters in digital programmable hardware, we set out to investigate their applicability as building blocks of artificial neural networks. We derive the nonlinear input-output firing rate relations for single multivibrator neurons as well as the equilibrium firing rate of large recurrent netwo...

A niche for ecosystem multifunctionality in global change research.

Concern about human modification of Earth's ecosystems has recently motivated ecologists to address how global change drivers will impact the simultaneous provisioning of multiple functions, or ecosystem multifunctionality (EMF). However, metrics of EMF have often been applied in global change studies with little consideration of the information they provide beyond single functions, or how and why EMF may respond to global change drivers. Here, we critically review the current state of this rapidly expandin...

Measuring the Single-Photon Temporal-Spectral Wave Function.

Temporal-spectral modes of light provide a fundamental window into the nature of quantum systems and offer a robust means for information encoding. Methods to precisely characterize the temporal-spectral state of light at the single-photon level thus play a central role in understanding single-photon sources and their applications in emerging optical quantum technologies. Here we demonstrate an optical reference-free method, which melds techniques from ultrafast metrology and single-photon spectral detectio...

Current progress in single sperm cryopreservation.

Sperm cryopreservation has been widely used in assisted reproduction, but conventional techniques are not suitable for the cryopreservation of small numbers of sperm. The application of the single sperm cryopreservation technique has significantly improved the clinical treatment of cryptozoospermia and non-obstructive azoospermia. Ever since Cohen et al first developed the method of single sperm cryopreservation in 1997, constant efforts have been made to develop the carriers for this technique. In this rev...

Lessons and perspectives for applications of stochastic models in biological and cancer research.

The effects of randomness, an unavoidable feature of intracellular environments, are observed at higher hierarchical levels of living matter organization, such as cells, tissues, and organisms. Additionally, the many compounds interacting as a well-orchestrated network of reactions increase the difficulties of assessing these systems using only experiments. This limitation indicates that elucidation of the dynamics of biological systems is a complex task that will benefit from the establishment of principle...

Quantifying Waddington's epigenetic landscape: a comparison of single-cell potency measures.

Estimating differentiation potency of single cells is a task of great biological and clinical significance, as it may allow identification of normal and cancer stem cell phenotypes. However, very few single-cell potency models have been proposed, and their robustness and reliability across independent studies have not yet been fully assessed.

Simultaneous Discrimination of Single-Base Mismatch and Full Match Using a Label-Free Single-Molecule Strategy.

Identification of single-base mismatches has found wide applications in disease diagnosis, pharmacogenetics and population genetics. However, there is still a great challenge in the simultaneous discrimination of single-base mismatch and full match. Combined with a nanopore electrochemical sensor, a shared-stem structure of molecular beacon (MB) was designed that did not need the labeling, but achieved an enhanced signal-to-background ratio (SBR) of ~10E4, high thermodynamic stability to bind with target se...

Single Crystals of Cubic Rare-Earth Pyrochlore Germanates: REGeO (RE = Yb and Lu) Grown by a High-Temperature Hydrothermal Technique.

Large single crystals of YbGeO in the cubic Fd3̅ m space group, are synthesized and characterized from a high-temperature hydrothermal method (650°C/200 MPa in 1 M KF). The cubic phase displays spin frustration and possibly nonclassical quantum-spin behavior at low temperature. This is the first report of single crystals of this important phase of size and quality suitable for single-crystal neutron diffraction.

Single cell RNA-seq data clustering using TF-IDF based methods.

Single cell transcriptomics is critical for understanding cellular heterogeneity and identification of novel cell types. Leveraging the recent advances in single cell RNA sequencing (scRNA-Seq) technology requires novel unsupervised clustering algorithms that are robust to high levels of technical and biological noise and scale to datasets of millions of cells.

Correlation between job security as motivation and career maturity among Japanese nursing students.

For nursing students, career maturity -an individual's readiness to cope with career development tasks and make age-appropriate career decisions- is an essential factor influencing their desire to continue the job after qualifying as a nurse. Although job security as motivation to become a nurse might influence the career maturity of nursing students, it has not been demonstrated. In this study I aimed to elucidate the correlation between job security as motivation and career maturity among Japanese nursing...

Construction of Synthetic Antibody Libraries.

Libraries of antibody fragments displayed on filamentous phages are now a widely used approach to isolate antibodies against virtually any target. We describe a simple protocol to make large and diverse libraries based on a single or a limited number of frameworks. The approach is flexible enough to be used with any antibody format, either single-chain (scFv, VHH) or multi-chain (Fv, Fab, (Fab')2), and to target in a single step the six complementarity-determining regions-or any other part-of the antibody m...

Comparative Analysis of Droplet-Based Ultra-High-Throughput Single-Cell RNA-Seq Systems.

Since its establishment in 2009, single-cell RNA sequencing (RNA-seq) has been a major driver behind progress in biomedical research. In developmental biology and stem cell studies, the ability to profile single cells confers particular benefits. Although most studies still focus on individual tissues or organs, the recent development of ultra-high-throughput single-cell RNA-seq has demonstrated potential power in characterizing more complex systems or even the entire body. However, although multiple ultra-...

Rainbow-Seq: Combining Cell Lineage Tracing with Single-Cell RNA Sequencing in Preimplantation Embryos.

We developed the Rainbow-seq technology to trace cell division history and reveal single-cell transcriptomes. With distinct fluorescent protein genes as lineage markers, Rainbow-seq enables each single-cell RNA sequencing (RNA-seq) experiment to simultaneously decode the lineage marker genes and read single-cell transcriptomes. We triggered lineage tracking in each blastomere at the 2-cell stage, observed microscopically inequivalent contributions of the progeny to the two embryonic poles at the blastocyst ...
