In selection decisions, decision makers often struggle to ignore irrelevant information, such as candidates' age, gender and attractiveness, which can lead to suboptimal decisions. Triparanol One way to correct the effects of these irrelevant attributes is to consider them as suppressor variables, and penalize individuals who unjustifiably benefit from them. Previous research demonstrated that people have difficulties doing so. In five experiments (N = 1325), we examined the mechanism at the core of people's ability to do so. We found that triggering System 2 did not improve participants' ability to correct for this bias. The majority of those who were successful did so even when denied the opportunity to deliberate. We suggest that logic intuition-not deliberation-is the basis for successfully considering irrelevant information as suppressors. Our results are in line with a revised dual-process approach, in which solving reasoning problems can occur directly through System 1 and does not require an override by a System 2's-based process.Exponential growth is frequently underestimated, an error that can have a heavy social cost in the context of epidemics. To clarify its origins, we measured the human capacity (N = 521) to extrapolate linear and exponential trends in scatterplots. Four factors were manipulated the function underlying the data (linear or exponential), the response modality (pointing or venturing a number), the scale on the y axis (linear or logarithmic), and the amount of noise in the data. While linear extrapolation was precise and largely unbiased, we observed a consistent underestimation of noisy exponential growth, present for both pointing and numerical responses. A biased ideal-observer model could explain these data as an occasional misperception of noisy exponential graphs as quadratic curves. Importantly, this underestimation bias was mitigated by participants' math knowledge, by using a logarithmic scale, and by presenting a noiseless exponential curve rather than a noisy data plot, thus suggesting concrete avenues for interventions.Every day, people face choices which could produce negative outcomes for others, and understanding these decisions is a major aim of social psychology. Here, we show that episodic simulation - a key psychological process implicated in other types of social and moral decision-making - can play a surprising role. Across six experiments, we find that imagining performing actions which adversely affect others makes people report a higher likelihood of performing those actions in the future. This effect happens, in part, because when people construe the actions as morally justified (as they often do spontaneously), imagining doing it makes them feel good. These findings stand in contrast to traditional accounts of harm aversion in moral psychology, and instead contribute to a growing body of evidence that people often cast harming others in a positive light.SARS-CoV-2 virus is the cause of COVID-19 pandemic and belongs to RNA viruses, showing great tendency to mutate. Several dozens of mutations have been observed on the SARS-CoV-2 virus, during the last two years. Some of the mutated strains show a greater infectivity and are capable of suppressing the earlier strains, through interference. In this work, kinetic and thermodynamic properties were calculated for strains characterized by various numbers and locations of mutations. It was shown that mutations lead to changes in chemical composition, thermodynamic properties and infectivity. Through competition, the phenomenon of interference of various SARS-CoV-2 strains was explained, which results in suppression of the wild type by mutant strains. Standard Gibbs energy of binding and binding constant for the Omicron (B.1.1.529) strain were found to be ΔBG⁰ = -45.96 kJ/mol and KB = 1.13 ∙ 10+8 M-1, respectively.

The neurophysiological dynamics of the occurrence of a stuttering event are largely unknown. This sensor-level EEG study investigated whether already the intention to speak alters the formation of the speech production network in stuttering.

We studied alpha (8-13Hz), low beta (15-25Hz) and high beta (25-30Hz) power modulation in 19 adults with developmental stuttering (AWS) and 19 fluently speaking control participants during speech intention.

Both groups show that the anticipation of overt reading coincides with broadband low-frequency suppression in posterior sensors, a common sign of network formation for speech production. Prior to fluent speech, frontotemporal alpha and low-beta power were weaker in AWS with mild stuttering but stronger in AWS with severe stuttering. These correlations were not significant prior stuttered speech. Further, post hoc comparisons confirmed the difference between AWS with mild and severe stuttering in low beta power.

AWS with more severe stuttering seem to show stronger maintenance of the current cognitive or sensorimotor state, as stuttering severity was associated with increased beta power. Increased beta power levels may influence subsequent speech preparation and execution processes.

Upcoming breakdowns of the speech production network as evident in actual stuttering are related to beta power during the intention to speak.

To assess the relationship between spinal reflexes and motor function in sub-acute (SAS) and chronic stroke (CS) patients.

Twelve SAS and 16 CS patients underwent electrophysiological assessment of heteronymous facilitation (HF), heteronymous inhibition (HI), disynaptic reciprocal inhibition (DRI), and D1 inhibition (D1). The Fugl-Meyer Assessment Lower Extremity (FMA-LE) and modified Ashworth scale (MAS) were assessed. The relationship between spinal reflexes and motor function was examined in a cross-sectional manner. SAS patients were also longitudinally evaluated before and after intensive rehabilitation for approximately 2months.

SAS patients with triceps surae muscle spasticity (MAS≥1) showed higher HF values (p=0.03) than those without spasticity. SAS patients with quadriceps muscle spasticity showed higher HF values (p<0.01); patients with hamstring muscle spasticity showed higher DRI value (disinhibition) (p<0.01) than those without spasticity. CS patients showed no significant correlation between spinal reflexes and motor function. The longitudinal study revealed a significant correlation between increase in D1 inhibition and FMA-LE improvement in SAS patients (r=0.69).

The association between impaired spinal reflexes varies with the stage of stroke; HF and DRI may be spasticity indicators in SAS patients.

Spinal reflexes as potential biomarkers may facilitate tailor-made rehabilitation of stroke patients.

The silicate laminate consists of silicon-oxygen at tetrahedral sites and aluminum-oxygen at octahedral sites. Since HNT has an abundant hydroxyl group on the surface with exceptional cation/anion exchange capacity, the surface-functionalized HNT could boost electrocatalytic activity. Hence, we have synthesized Ni, Co, and Cu metal oxy/hydroxides functionalized HNT by a facile hydrothermal method for HER. Among them, Co(OH)2@HNT on flexible carbon cloth displays an ultra-low overpotential of 65 mV at 10 mA cm-2 current density and Tafel slope of 181 mV dec-1 and also exhibited a larger exchange current density of 3.98 mA cm-2 in alkaline 1 M KOH electrolyte due to superior electrostatic affinity between OH- and Co2+. The electrolyzers with anion exchange membrane consisting of RuO2||Co(OH)2@HNT show remarkable stability of over 50 h at 10 mA cm-2 in alkaline electrolyte. The post stability sample retains the same surface oxidation state which confirms the robustness of the electrocatalyst. The reported results are far better than many of the transition metal oxides/chalcogenides electrocatalysts and hence it is expected that HNT could act as a potential alternative candidate to replace the benchmark platinum catalyst.

It is hypothesized that the performance of a chemical inhibitor to interfere with the precipitation and scaling of calcite (calcium carbonate, CaCO

) is achieved through its chelating interaction with calcium ions. The effectiveness of a chemical inhibitor in removing existing scales from the mineral surfaces is proposed to rely on its ability to modify the calcite crystal structures.

Bulk scaling tests and dynamic adsorption experiments using a quartz crystal microbalance with dissipation monitoring were conducted to systematically investigate the scaling behaviours (i.e., buildup and breakup processes) of calcite crystals, in the absence and presence of chemical inhibitors, that include polyacrylic acid, sodium hexametaphosphate, 2-phosphonobutane-1,2,4-tricarboxylic acid, and diethylenetriamine penta(methylene phosphonic acid). Scanning electron microscope imaging and thermodynamic characterization using isothermal titration calorimetry were further applied to reveal the surface interactions that conth water. This work provides useful insights into the fundamental interactions of chemical inhibitors and calcite, with implications for the development of effective chemical solutions for anti-scaling and descaling applications.Alcohols are discovered for the first time to tune the morphology of poly(vinyl benzyl chloride)-poly(3-methacryloxypropyltrimethoxysilane) (PVBC-PMPS) composite particles through seeded emulsion polymerization within the alcohol/water mixture. Here, monodispersed linear PVBC particles was synthesized through the dispersion polymerization and employed as the seeds. The as-obtained PVBC-PMPS composite particles could be dramatically tuned from core-shell structures to snowman-like particles, to dumbbell-shaped particles, to inverse snowman-like particles when the ethanol content in reaction mixtures is only adjusted within a narrow range. The morphology of fresh PMPS bulges was observed after removing the linear PVBC seeds with N,N'-dimethyl formamide, and their formation mechanism was studied by monitoring the free radical polymerization and sol-gel process of 3-methacryloxypropyltrimethoxysilane. It has been confirmed that the sol-gel kinetics were the main factor on the particles' morphology. In addition, morphologies of PVBC-PMPS particles were also varied by the MPS feeding amount, types of the co-solvent and pH values of alcohol/water mixtures.Metal-organic frameworks (MOFs) have been considered as promising nanofillers to fabricate mixed matrix membranes for water treatment. However, manipulating distribution of MOFs nanoparticles in the membrane matrix remains a great challenge. In this study, UiO-66 was firstly coated by magnetic Ni via an in-situ reduction reaction, and then incorporated into polyethersulfone (PES) membrane matrix to prepare PES-Ni@UiO-66 membrane. The magnetic Ni allowed to manipulate the distribution of magnetic Ni@UiO-66 in the phase-inversion process by an external magnetic field. The hydrophilic Ni@UiO-66 can be pulled onto membrane surface by the magnetic force, endowing the prepared membrane with rather higher hydrophilicity. The prepared membrane exhibited superior water permeability with a pure water flux of 611.5 ± 19.8 L·m-2·h-1 and improved antifouling performance. Moreover, benifiting from photocatalytic activity of the exposed Ni@UiO-66 on membrane surface, the obtained PES-Ni@UiO-66 membrane demonstrated excellent photocatalytic self-cleaning ability with a flux recovery rate (FRR) higher than 95% under UV irradiation.
