Self-assembly of chromatic patchy particles with tetrahedrally arranged patches.

The achievement of selectivity in the formation of cubic diamond is challenging due to the emergence of competing phases such as its hexagonal polymorph or clathrates possessing similar free energy. Although both polymorphs exhibit a complete photonic bandgap, cubic diamond exhibits it at lower frequencies than the hexagonal counterpart, positioning it as a promising candidate for photonic applications. Herein, we demonstrate that the 1 : 1 mixture of identical patchy particles cannot selectively form the cubic diamond polymorph due to the frustrations present in the system that are manifested in the primary adsorption layer and propagate as the film grows.

Introducing the Narcissistic Antagonism Scale: A missing puzzle piece in the assessment of momentary narcissism.

Narcissism is a relatively stable personality trait, which is most accurately described by three facets: agentic, antagonistic, and neurotic. Existing studies support the central role of antagonistic narcissism and its role in explaining the process of fluctuation in narcissism. However, there is a lack of a suitable adjective-based measure of antagonistic narcissism, resulting in intensive longitudinal studies assessing only agentic and neurotic narcissism.

Midwifery Students' Views on NANDA-I Diagnoses and Care Plans Used in Clinical Practice.

Background: Developing a care plan for patients is not specific to nursing or midwifery; it is the case in every situation where patients seek help from care providers. Midwifery students draw upon NANDA-I diagnoses while developing care plans (CPs) in clinical practices, and plan and apply their care accordingly. This study aims to identify the views of midwifery students on the NANDA-I diagnoses and CPs that they use in clinical practice.

Interplay between the Formation of Colloidal Clathrate and Cubic Diamond Crystals.

Controlling the valency of directional interactions of patchy particles is insufficient for the selective formation of target crystalline structures due to the competition between phases of similar free energy. Examples of such are stacking hybrids of interwoven hexagonal and cubic diamonds with (i) its liquid phase, (ii) arrested glasses, or (iii) clathrates, all depending on the relative patch size, despite being within the one-bond-per-patch regime. Herein, using molecular dynamics simulations, we demonstrate that although tetrahedral patchy particles with narrow patches can assemble into clathrates or stacking hybrids in the bulk, this behavior can be suppressed by the application of external surface potential.

On the selective formation of cubic tetrastack crystals from tetravalent patchy particles.

Achieving the formation of target open crystalline lattices from colloidal particles is of paramount importance for their potential application in photonics. Examples of such desired structures are the diamond, tetrastack, and pyrochlore lattices. Here, we demonstrate that the self-assembly of tetravalent patchy particles results in the selective formation of cubic tetrastack crystals, both in the bulk and in the systems subjected to external fields exerted by the solid substrate.

Confinement enhanced viscosity vs shear thinning in lubricated ice friction.

The ice surface is known for presenting a very small kinetic friction coefficient, but the origin of this property remains highly controversial to date. In this work, we revisit recent computer simulations of ice sliding on atomically smooth substrates, using newly calculated bulk viscosities for the TIP4P/ice water model. The results show that spontaneously formed premelting films in static conditions exhibit an effective viscosity that is about twice the bulk viscosity.

The peaks and valleys of narcissism: The factor structure of narcissistic states and their relations to trait measures.

Although interindividual differences in narcissism are well studied, little is known about assessing narcissism at the within-person level. To fill this research gap, we investigated whether the narcissism construct is represented in the same way at the between- and within-person levels. We analyzed four established narcissism measures across multiple studies.

Pursuing colloidal diamonds.

The endeavor to selectively fabricate a cubic diamond is challenging due to the formation of competing phases such as its hexagonal polymorph or others possessing similar free energy. The necessity to achieve this is of paramount importance since the cubic diamond is the only polymorph exhibiting a complete photonic bandgap, making it a promising candidate in view of photonic applications. Herein, we demonstrate that due to the presence of an external field and delicate manipulation of its strength we can attain selectivity in the formation of a cubic diamond in a one-component system comprised of designer tetrahedral patchy particles.

Amphiphilic Janus Particles Confined in Symmetrical and Janus-Like Slits.

We use Monte Carlo simulations to investigate the behavior of Janus spheres composed of attractive and repulsive parts confined between two parallel solid surfaces. The slits with identical and competing walls are studied. The adsorption isotherms of Janus particles are determined, and the impact of the density in the pore on the morphology is discussed in detail.

Self-diffusion and shear viscosity for the TIP4P/Ice water model.

With an ever-increasing interest in water properties, many intermolecular force fields have been proposed to describe the behavior of water. Unfortunately, good models for liquid water usually cannot provide simultaneously an accurate melting point for ice. For this reason, the TIP4P/Ice model was developed for targeting the melting point and has become the preferred choice for simulating ice at coexistence.

Investigation of the Necessity of Aspiration During the Intramuscular Injection Administered in the Ventrogluteal Site and Its Effect on Pain: A Randomized Controlled Trial.

This experimental study, which was conducted to examine the necessity of aspiration procedure and its effect on pain in intramuscular (IM) injections made into the ventrogluteal site (VGS), is randomized controlled and double-blind. The patients in the study group ( = 834) were assigned to the IM group with the aspiration period of 5 to 10 seconds (Implementation Group A-IGA), the aspiration period of 1 to 2 seconds (Control Group-CG), and no aspiration (Implementation Group B-IGB) according to stratified block randomization list. Patients' pain levels were evaluated with the Visual Analog Scale (VAS).

Ice friction at the nanoscale.

The origin of ice slipperiness has been a matter of great controversy for more than a century, but an atomistic understanding of ice friction is still lacking. Here, we perform computer simulations of an atomically smooth substrate sliding on ice. In a large temperature range between 230 and 266 K, hydrophobic sliders exhibit a premelting layer similar to that found at the ice/air interface.

Coarse-Grained Modeling of On-Surface Self-Assembly of Mixtures Comprising Di-Substituted Polyphenyl-Like Compounds and Metal Atoms of Different Sizes.

We use coarse-grained molecular dynamics simulations to investigate the phase behavior of binary mixtures of di-substituted polyphenyl-like compounds and metal atoms of different sizes. We have estimated the possible on-surface behavior that could be useful for the target design of particular ordered networks. We have found that due to the variation of system conditions, we can observe the formation of the parallel, square, and triangular networks, Archimedean tessellation, and "spaghetti wires.

Frequency of Clinical Alarms in Intensive Care Units and Nurses' Sensitivity to Them: An Observational Study.

Background: All clinical alarms require nurses to respond even if an intervention is not needed. Nurses are expected to respond appropriately to each alarm and establish priorities among their care practices accordingly. This study was conducted to examine the number and types of clinical device alarms used in intensive care units, the duration of their activation, and nurses' degree of sensitivity to them.

Specificity of the chromatic noise influence on the luminance contrast discrimination to the color vision phenotype.

Many studies have examined how color and luminance information are processed in the visual system. It has been observed that chromatic noise masked luminance discrimination in trichromats and that luminance thresholds increased as a function of noise saturation. Here, we aimed to compare chromatic noise inhibition on the luminance thresholds of trichromats and subjects with severe deutan or protan losses.

Academic dishonesty among university students: The roles of the psychopathy, motivation, and self-efficacy.

Academic dishonesty is a common problem at universities around the world, leading to undesirable consequences for both students and the education system. To effectively address this problem, it is necessary to identify specific predispositions that promote cheating. In Polish undergraduate students (N = 390), we examined the role of psychopathy, achievement goals, and self-efficacy as predictors of academic dishonesty.

Simulations of the 2D self-assembly of tripod-shaped building blocks.

We introduce a molecular dynamics (MD) coarse-grained model for the description of tripod building blocks. This model has been used by us already for linear, V-shape, and tetratopic molecules. We wanted to further extend its possibilities to trifunctional molecules to prove its versatility.

Longitudinal visual acuity development in ZIKV-exposed children.

Purpose: To follow the visual acuity development of children exposed to or infected with the Zika virus (ZIKV) during gestation and to relate potential visual acuity deficits to their clinical condition.

Methods: In this prospective study, visual acuity was measured via Teller Acuity Cards in three groups of children: (1) those with confirmed ZIKV exposure (ZE) through the mother only, (2) those with confirmed infection (ZI), and (3) unaffected controls. Visual acuity was measured 2-4 times in each child during the first 30 months of age.

Self-assembly of Janus disks confined in a slit.

Using Monte Carlo simulations, we investigate the self-organization of Janus disks confined in two-dimensional slits. Janus particles are modeled as circles composed of attractive and repulsive parts. We consider the slits with identical walls and slits with competing walls (the so-called Janus-like pores).

Effect of the Decrease in Luminance Noise Range on Color Discrimination of Dichromats and Trichromats.

Color vision assessment can be done using pseudoisochromatic stimuli, which has a luminance noise to eliminate brightness differences between the target and background of the stimulus. It is not clear the influence of the luminance noise on color discrimination. We investigated the effect of change in the luminance noise limits on color discrimination.

Distribution and density of mixed-input ON bipolar cells of the goldfish (Carassius auratus) during growth.

Neurons are continuously produced at different rates and locations in the teleost retina. Goldfish rods are homogeneously distributed and maintain a stable density throughout growth, whereas little is known about their postsynaptic partners. We examined the distribution and density of mixed-input ON bipolar cells (ON mBCs) in 57 goldfish of various sizes by immunolabeling their retinas with an antibody against PKCα and counting PKCα-positive neurons in wholemounts.
