The Modified Behavioral Pain Scale (MBPS) was designed to assess procedural pain in infants and is considered valid for assessing immunisation pain. The aim of this study was to assess the practical and psychometric properties of the MBPS when applied to other commonly performed procedures. Twenty-six clinicians independently applied the MBPS scale to segments of video collected from 100 children aged six to 42 months undergoing one of four procedures in the emergency department. Positive correlation between MBPS and VASobs pain (r = 0...

Rhizopus oryzae lipase (ROL) is an important industrial enzyme limited in application due to its low production in native strains. Here, we used a new combined strategy to overexpress ROL in Pichia pastoris. An efficient method based on bio-brick was developed to construct a series of vectors harboring different copy numbers of ROL gene cassettes, which were then transformed into P. pastoris GS115 to generate a strain with specific copy numbers of ROL. An optimized gene-dosage recombinant strain of GS115/pAOα-5ROL 11# harboring five copies of ROL was screened, revealing production of the highest activity (2700 U/mL), which was 8-fold higher than that of the strain harboring one copy...

There continues to be a need in the field of psychology for measures that quantify qualitative data in dynamically rich and clinically meaningful ways. The Social Cognition and Object Relations Scale-Global Rating Method (SCORS-G; Westen, 1995) is a clinician-rated measure with a strong theoretical foundation that assesses sophisticated underlying constructs, specifically 8 dimensions of object relations (Stein & Slavin-Mulford, 2018 ). The SCORS-G has steadily increased in popularity and this special section of the Journal of Personality Assessment reflects this growing interest...

We have strategically incorporated three different fluorophores at tren to construct a multi-energy donor/acceptor "smart" probe L. This probe operates by using three-dimensional scales (response time, wavelength and fluorescence intensity) which allows for the selective recognition and discrimination of the Cu 2+ , Hg 2+ , Fe 3+ and F - ions.

PURPOSE: Plastic phantoms are commonly used in daily routine for dosimetric tasks in radiation therapy. Despite the fact that water is the reference medium according to the dosimetric protocols, measurements with non-water phantoms are easier to be performed. To succeed absorbed dose determination, certain scaling factors have to be applied to the acquired measurements. Taking into account the increased availability of three-dimensional (3D) printing, we attempted to obtain scaling factors for polylactic acid (PLA), a commonly used thermoplastic material for 3D printing...

We consider the one-dimensional model of a spin glass with independent Gaussian-distributed random interactions, which have mean zero and variance 1/|i-j|^{2σ}, between the spins at sites i and j for all i≠j. It is known that, for σ>1, there is no phase transition at any nonzero temperature in this model. We prove rigorously that, for σ>3/2, any translation-covariant Newman-Stein metastate for the ground states (i.e., the frequencies with which distinct ground states are observed in finite-size samples in the limit of infinite size, for given disorder) is trivial and unique...

In quantum thermodynamics, effects of finiteness of the baths have been less considered. In particular, there is no general theory which focuses on finiteness of the baths of multiple conserved quantities. Then, we investigate how the optimal performance of generalized heat engines with multiple conserved quantities alters in response to the size of the baths. In the context of general theories of quantum thermodynamics, the size of the baths has been given in terms of the number of identical copies of a system, which does not cover even such a natural scaling as the volume...

We employ numerical simulations and finite-size scaling techniques to investigate the properties of the dynamic phase transition that is encountered in the Blume-Capel model subjected to a periodically oscillating magnetic field. We mainly focus on the study of the two-dimensional system for various values of the crystal-field coupling in the second-order transition regime. Our results indicate that the present nonequilibrium phase transition belongs to the universality class of the equilibrium Ising model and allow us to construct a dynamic phase diagram, in analogy with the equilibrium case, at least for the range of parameters considered...

BACKGROUND: Due to the heterogeneity of depressive symptoms-which can include depressed mood, anhedonia, negative cognitive biases, and altered activity levels-researchers often use a combination of depression rating scales to assess symptoms. This study sought to identify unidimensional constructs measured across rating scales for depression and to evaluate these constructs across clinical trials of a rapid-acting antidepressant (ketamine). METHODS: Exploratory factor analysis (EFA) was conducted on baseline ratings from the Beck Depression Inventory (BDI), the Hamilton Depression Rating Scale (HAM-D), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Snaith-Hamilton Pleasure Rating Scale (SHAPS)...

Designing well-controlled hierarchical structures on micrometer and nanometer scales represents one of the most important approaches for upgrading the catalytic abilities of electrocatalysts. Although NiFe (oxy)hydroxide has been widely studied as a water oxidation catalyst due to its high catalytic capability and abundance, its structural manipulation has been greatly restricted due to its inherent crystallographic stacking feature. In this work, we report for the first time the construction of a nanotube structure of NiFe (oxy)hydroxide with an inner Ni-rich layer, which was radially aligned on a macroporous nickel foam...

A key enabling step in leveraging the properties of nanoparticles (NPs) is to explore new, simple, controllable, and scalable nanotechnologies for their syntheses. Among 'wet' methods, cathodic corrosion has been used to synthesize catalytic aggre-gates with some control over their size and preferential faceting. Here, we report on a modification of the cathodic corrosion method for producing a range of non-aggregated nanocrystals (Pt, Pd, Au, Ag, Cu, Rh, Ir, Ni) and nanoalloys (Pt50Au50, Pd50Au50, AgxAu100-x) with potential for scaling up the production rate...

Using coumarin-modified diphenylalanine (CO-FF) and gamma-cyclodextrin (gamma-CD) as building blocks, one-dimensional nanofibers with several nanometers in width and tens of micrometers in length were successfully constructed. Through the photo-dimerization of coumarin units in CO-FF/gamma-CD complexes, the resultant nanofibers could cross-linked to organic 2D thin films with a lateral dimension of tens of micrometers and a thickness of nanometers. The resultant thin films exhibited a sig-nificant fluorescence enhancement for twisted intramolecular charge-transfer (TICT) molecules and effective removal of pollut-ant from water through filtration...

Highly efficient, robust, and cheap water oxidation electrodes are of great significance for large-scale production of hydrogen by electrolysis of water. Here, a self-supported stainless steel (SS) nanocone array coated with a layer of nanoparticulate Ni-Fe oxides/(oxy)hydroxides was fabricated by a facile, low-cost, and easily scalable two-step process. The construction of a nanocone array on the surface of AISI 304 SS plate by acid corrosion greatly enlarged the specific surface area of the substrate, and the subsequent formation of a layer of Ni-Fe oxides/(oxy)hydroxides featuring the NiFe 2 O 4 spinel phase on the nanocone surface by electrodeposition of [Ni(bpy) 3 ] 2+ significantly enhanced the intrinsic activity and the stability of the SS-based electrode...
