The analogue-I and analogue-me refer to mental self-relevant images that take a first-person vs. third-person perspective, respectively. Mental self-analogues are essential for goal setting, planning, and rehearsal of behavioral strategies, but they often fuel emotional and interpersonal problems when people react to their analogue selves as if they were real. This article examines the beneficial and detrimental consequences of the analogue-I and analogue-me, with a focus on egoic reactions that arise from how people think about themselves in their own minds. Phenomena such as counterfactual thinking, interpersonal conflict, jealousy, and overreactions to inconsequential events are used to illustrate the advantages and disadvantages of the mental self-analogues.

A novel biomimetic DNA analogue with fluorescence has been synthesized to generate functional supramolecular architectures. Experimental studies show that triaminopyrimidine nucleoside (2) undergoes a sterically controlled self-assembly into hydrogen-bonded linear tapes and hexameric rosettes. Self-association of the hydrogen-bonded triamino-pyrimidine-cyanuric acid complex into elongated, rodlike nanostructures was shown by dynamic light scattering and transmission electron microscopy, suggesting hierarchical formation of higher-order, π-stacked assemblies. The hydrogen-bond self-assembly of the DNA analogue decreased the fluorescence of the nucleosides. This guest-induced fluorescence quenching can be used to develop DNA-hybridization probes. MM~+ molecular modelling and semi-empirical molecular orbital PM3 calculations (1) predicted the incorporation of triaminopyrimidine nucleoside into new types of artificial DNA strands and triplex formation with natural, complementary DNA strands containing thymine (1).

We construct a self-contained statistical-mechanical model for self-organization that emulates the hierarchical properties of the nonlinear dynamics towards the attractors that define the period or band doubling route to or out of chaos. The aforementioned dynamics translates into a sequential partitioning of an otherwise conventional thermal system into isolated compartments that privileges progressively lower entropies, while a new set of configurations emerges due to the multiplicities of the secluded portions. The initial canonical balance between numbers of configurations and Boltzmann-Gibbs (BG) statistical weights is drastically altered and ultimately eliminated by the sequential procedure that mirrors the actions of the attractor. However, the emerging set of group configurations implies a different and novel entropy growth process that eventually upsets the original loss and has the capability of marginally locking the system into a self-organized state with characteristics of criticality, therefore reminiscent in spirit to the so-called self-organized criticality.

The self-rating scale item (SRSI) is a single-item self-report adherence measure that uses adjectives in a 5-point Likert scale, from "very poor" to "excellent," to describe medication adherence over the past 4 weeks. This study investigated the SRSI in 2,399 HIV-infected patients in routine care at two outpatient primary HIV clinics. Correlations between the SRSI and four commonly used adherence items ranged from 0.37 to 0.64. Correlations of adherence barriers, such as depression and substance use, were comparable across all adherence items. General estimating equations suggested the SRSI is as good as or better than other adherence items (p's <0.001 vs. <0.001-0.99) at predicting adherence-related clinical outcomes, such as HIV viral load and CD4+ cell count. These results and the SRSI's low patient burden suggest its routine use could be helpful for assessing adherence in clinical care and should be more widespread, particularly where more complex instruments may be impractical. ? 2012 Springer Science+Business Media New York.

Abstract Background The 5‐visual analogue scale Richards‐Campbell Sleep Questionnaire subjective sleep measure is widely used in intensive care. A cut‐off score indicative of good quality sleep has not been established and is required to guide the categorisation of individual patient and unit wide sleep quality. Design and Methods The aim was to determine the global Richards‐Campbell Sleep Questionnaire cut‐off score for good to very good sleep during an intensive care unit stay in non‐ventilated patients. The study was a secondary (cohort) retrospective analysis of patient self‐report data (n?=?32) from an interventional study testing a sleep promotion bundle. The Standards for Reporting Diagnostic Accuracy studies statement were used to report the study. The study was conducted in two mixed adult 12 and 20‐bed ICUs of a tertiary referral hospital in a metropolitan area. In the morning, eligible patients were administered the Richards‐Campbell Sleep Questionnaire together with a 5‐category item Likert scale in which patients rated their nocturnal sleep quality as ‘very poor’, ‘poor’, ‘fair’, ‘good’ and ‘very good’. Receiver Operator Curve analysis was performed. Results Thirty‐seven per cent (n?=?32) of the total sample of 84 adult intensive care patients were females. The median age was 61.5 (51, 72) years. Self‐reported median global Richards‐Campbell Sleep Questionnaire score was 54.4 (30.1, 77.1) mm. A global score of ≥63.4?mm was the optimal cut‐off for self‐reported ‘good sleep’ (sensitivity: 87%, specificity: 81% and area under the curve: 0.896). Conclusions Although the study requires replication in ventilated patients and other ICU settings, the cut‐off score (63?mm) could be used to guide the categorisation of individual patient and unit wide sleep quality.

Synthesis and properties of a novel meso-oxo carbaphlorin analogue embedded with an N-free pyrazole moiety are described. The N-benzyl precursor was prepared by a [3 + 1]-MacDonald condensation of N-benzyl pyrazole dialdehyde and b-alkyl-substituted tripyrrane dicarboxylic acid and subsequent oxidation by ferric chloride. Upon deprotection of the benzyl group, the resulting N-free oxophlorin analogue formed a unique supramolecular dimer through mutual hydrogen bonding interactions between the pyrazole NH and meso-carbonyl group. The assembled behaviour was characterised by various spectroscopies, X-ray crystallographic analysis and vapour pressure osmometry. Under the similar reaction conditions, the condensation of meso-phenyl-substituted tripyrrane derivative afforded an unprecedented tetrapyrrolic macrocycle fused with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone unit at their a-pyrrolic positions. The X-ray crystallographic analysis of the macrocycle revealed a twisted core structure, and nonaromatic nature was elucidated.

This work presents an in-depth wide-frequency band assessment of 28 nm FDSOI MOSFETs for analogue and RF applications.The focus is mainly on such figures of merit (FoM) as the transconductance g(m), the output conductance g(d), the intrinsic gain A(v), and the cut-off frequencies f(T) and f(max). Firstly, 28 nm FDSOI MOSFETs are compared with other advanced devices and are shown to outperform them. Secondly, g(m)-A(v), analogue metric is demonstrated to be affected by operation frequency. Small-signal parameters variation is limited and dominated by self-heating effect. This is in contrast to the first generation of ultra-thin body and BOX devices without a ground plane where coupling through the substrate has a considerable effect. Thirdly, the self-heating effect is analysed and shown to be smaller than previously predicted by simulations for such devices. Fourthly, it is shown that f(T) of similar to 280 GHz and f(max) of similar to 250 GHz are reachable in the shortest devices. These values are compared to those of the first generation of UTBB devices through the effect of parasitic elements. (C) 2015 Elsevier Ltd. All rights reserved.

A CMOS analogue circuit is proposed that computes the sum of two voltages. The circuit is self-biased, only requires a small number of transistors, and offers good accuracy over a wide range of input values. The design makes no special demands on device aspect ratios and could offer an economic alternative to conventional approaches. Simulation results have shown that total harmonic distortion (THD) is lower than -40 dB for output voltages up to 4 V peak to peak.

? 2022 The Author(s)The preparation of a caesium inclusion complex of the molecular cube [{CoIII(Me3-tacn)}4{FeII(CN)6}4]}]4–, a mixed valent molecular Prussian Blue Analogue bearing bridging cyanido ligands, has been achieved by following a redox-triggered self-assembly process in aqueous solution. The assembly has been shown to be Cs-preferred as, even in the presence of Na+ in solution, no Na-encapsulated have been found in the assembled product when Cs+ is present in the reaction medium. Even so, the tightness of the system produces large amounts of a void cubic structure whenever not large excesses of Cs+ are present. The species is robust, extremely soluble in aqueous media, pH-stable in the 1–13 range, and redox inactive between ?400 and 600 mV. The molecular species has been characterised by UV–vis, ICP, multinuclear NMR spectroscopy, and electrochemistry. As expected from previous data reported, the complex in aqueous solution is totally inert to cation exchange, the leaching of the encapsulated Cs+ being hampered by the small size of the cube portal.
