Memorable Messages from Family Members About Mental Health: Young Adult Perceptions of Relational Closeness, Message Satisfaction, and Clinical Help-Seeking Attitudes

ABSTRACT This study investigates memorable messages about mental health that young adults (YAs) recall receiving from family members. A memorable messages conceptual framework is adopted to explore message types and their associations with relevant individual and relational outcomes. Findings from a study of 193 memorable messages about mental health revealed three types of messages about mental health transmitted by family members: strategizing, normalizing, and minimizing messages. Statistical analyses indicated that memorable message types were significantly related to YA satisfaction with the message, perceptions of relational closeness between the message source and the YA message recipient, and YA attitudes about mental-health help seeking. Overall, participants who reported minimizing messages about mental health also reported the least favorable outcomes on the set of dependent variables. Implications of these findings and future directions for research are discussed.
Analyzing randomized controlled interventions: Three notes for applied linguists

I discuss three common practices that obfuscate or invalidate the statistical analysis of randomized controlled interventions in applied linguistics. These are (a) checking whether randomization produced groups that are balanced on a number of possibly relevant covariates, (b) using repeated measures ANOVA to analyze pretest-posttest designs, and (c) using traditional significance tests to analyze interventions in which whole groups were assigned to the conditions (cluster randomization). The first practice is labeled superfluous, and taking full advantage of important covariates regardless of balance is recommended. The second is needlessly complicated, and analysis of covariance is recommended as a more powerful alternative. The third produces dramatic inferential errors, which are largely, though not entirely, avoided when mixed-effects modeling is used. This discussion is geared towards applied linguists who need to design, analyze, or assess intervention studies or other randomized controlled trials. Statistical formalism is kept to a minimum throughout.
Standalone solar power generation using 3-phase multilevel inverter with simpler basic unit cells

A standalone 3-phase half-bridge multilevel inverter with simple basic unit cells coupled to solar power generation is proposed. This proposed inverter is able to operate in either charging mode or inverter mode, which is suitable for solar power generation using photovoltaic modules. The active switches (power MOSFET) in this proposed inverter is operating at fundamental or twice the fundamental frequency of the AC mains, resulting in lower switching losses. The proposed topology operating in inverter mode has been verified via simulation studies. The simulation results show that the proposed inverter is capable of supplying AC voltages with low total harmonic distortion to the load. In addition, the proposed inverter requires lower number of power MOSFETs and gate driver units, which improves the reliability.
0 60 20 49 v 1 1 3 Fe b 20 06 Tetrads in Yang-Mills geometrodynamics

A new set of tetrads is introduced within the framework of SU(2)×U(1) Yang-Mills field theories in curved spacetimes. Each one of these tetrads diagonalizes separately each term of the Yang-Mills stress-energy tensor. Therefore, three pairs of planes also known as blades, can be defined, and make up the underlying geometrical structure, at each point. These tetrad vectors are gauge dependent on one hand, and also in their definition, there is an additional inherent freedom in the choice of two vector fields. In order to get rid of the gauge dependence, another set of tetrads is defined, such that the only choice we have to make is for the two vector fields. A particular choice is made for these two vector fields such that they are gauge dependent, but the transformation properties of the tetrads are analogous to those already known for curved spacetimes where only electromagnetic fields are present. This analogy allows to establish group isomorphisms between the local gauge group SU(2), and the tensor product of the groups of local Lorentz tetrad transformations, either on blade one or blade two.
VISUALIZING VIDEO SOUNDS THROUGH SOUND WORD ANIMATION

Sound information in video plays an important role in constructing audience experience. On the other hand, there are many circumstances where the audience cannot watch video with sounds. Subscripts are conventionally used as visual aids to provide the missing sound information. However, conventional subscripts are far less expressive for non-verbal sounds since it is designed to visualize speech sound. To address this problem, we propose a method to automatically recognize sound categories of non-verbal video-sounds and transform it to sound words for visualization. The sound word is animated in response to the change of the sound from moment to moment. Its position also changes dynamically depending on the position of the sound source object in the video. This will provide natural visual representation of non-verbal sounds with rich information about sound category and dynamics. The sound word animation is not only useful when watching video without sound, but also enjoyable for audience since it works as visual effects to enhance the visual scene.
High‐Resolution Genome Screen for Bone Mineral Density in Heterogeneous Stock Rat

We previously demonstrated that skeletal mass, structure, and biomechanical properties vary considerably in heterogeneous stock (HS) rat strains. In addition, we observed strong heritability for several of these skeletal phenotypes in the HS rat model, suggesting that it represents a unique genetic resource for dissecting the complex genetics underlying bone fragility. The purpose of this study was to identify and localize genes associated with bone mineral density in HS rats. We measured bone phenotypes from 1524 adult male and female HS rats between 17 and 20 weeks of age. Phenotypes included dual‐energy X‐ray absorptiometry (DXA) measurements for bone mineral content and areal bone mineral density (aBMD) for femur and lumbar spine (L3–L5), and volumetric BMD measurements by CT for the midshaft and distal femur, femur neck, and fifth lumbar vertebra (L5). A total of 70,000 polymorphic single‐nucleotide polymorphisms (SNPs) distributed throughout the genome were selected from genotypes obtained from the Affymetrix rat custom SNPs array for the HS rat population. These SNPs spanned the HS rat genome with a mean linkage disequilibrium coefficient between neighboring SNPs of 0.95. Haplotypes were estimated across the entire genome for each rat using a multipoint haplotype reconstruction method, which calculates the probability of descent for each genotyped locus from each of the eight founder HS strains. The haplotypes were tested for association with each bone density phenotype via a mixed model with covariate adjustment. We identified quantitative trait loci (QTLs) for BMD phenotypes on chromosomes 2, 9, 10, and 13 meeting a conservative genomewide empiric significance threshold (false discovery rate [FDR] = 5%; p < 3 × 10−6). Importantly, most QTLs were localized to very small genomic regions (1–3 megabases [Mb]), allowing us to identify a narrow set of potential candidate genes including both novel genes and genes previously shown to have roles in skeletal development and homeostasis. © 2014 American Society for Bone and Mineral Research.
Energy Efficiency in Public Buildings through Context-Aware Social Computing

The challenge of promoting behavioral changes in users that leads to energy savings in public buildings has become a complex task requiring the involvement of multiple technologies. Wireless sensor networks have a great potential for the development of tools, such as serious games, that encourage acquiring good energy and healthy habits among users in the workplace. This paper presents the development of a serious game using CAFCLA, a framework that allows for integrating multiple technologies, which provide both context-awareness and social computing. Game development has shown that the data provided by sensor networks encourage users to reduce energy consumption in their workplace and that social interactions and competitiveness allow for accelerating the achievement of good results and behavioral changes that favor energy savings.

Self-organization of nano-lines and dots triggered by a local mechanical stimulus

When a local mechanical perturbation is applied to the surface of a thin film of a mechanically interlocked molecule (a rotaxane), the molecules self-organize into periodic arrays of discrete dots or lines. The dimensionality of the nanostructures depends on whether the mechanical stimulus acts along a 1D line or over a 2D area. The size (50–500 nm) and periodicity (100–600 nm) of the patterns are controlled solely by the film thickness. This self-organization at the mesoscopic scale occurs via a nucleation-ripening mechanism eased by the relatively low energy barriers of the intramolecular rearrangement introduced by the mechanical bond. The phenomenon can be exploited as a bottom-up nanofabrication method.
Multi-Document Summarization of Persian Text using Paragraph Vectors

A multi-document summarizer finds the key topics from multiple textual sources and organizes information around them. In this paper we propose a summarization method for Persian text using paragraph vectors that can represent textual units of arbitrary lengths. We use these vectors to calculate the semantic relatedness between documents, cluster them to a number of predetermined groups, weight them based on their distance to the centroids and the intra-cluster homogeneity and take out the key paragraphs. We compare the final summaries with the gold-standard summaries of 21 digital topics using the ROUGE evaluation metric. Experimental results show the advantages of using paragraph vectors over earlier attempts at developing similar methods for a low resource language like Persian.
Ribocomputing devices for sophisticated in vivo logic computation

Synthetic biology aims to create functional devices, systems, and organisms with novel and useful functions taking advantage of engineering principles applied to biology. Despite great progress over the last decade, an underlying problem in synthetic biology remains the limited number of high-performance, modular, composable parts. A potential route to solve parts bottleneck problem in synthetic biology utilizes the programmability of nucleic acids inspired by molecular programming approaches that have demonstrated complex biomolecular circuits evaluating logic expressions in test tubes. Using a library of de-novo-designed toehold switches with orthogonality and modular composability, we demonstrate how toehold switches can be incorporated into decision-making RNA networks termed ribocomputing devices to rapidly evaluate complex logic in living cells. We have successfully demonstrated a 4-input AND gate, a 6-input OR gate, and a 12-input expression in disjunctive normal form in E. coli. The compact encoding of ribocomputing system using a library of modular parts is amenable to aggressive scale-up towards complex control of in vivo circuitry towards autonomous behaviors and biomedical applications.
Body composition at birth in preterm infants between 30 and 36 weeks gestation

The American Academy of Pediatrics calls for aggressive management of preterm infants to achieve body composition approximating that of the healthy infant in utero. Air displacement plethysmography (ADP) has been validated for assessment of body composition in preterm infants and could be used to monitor their nutritional status during hospitalization. Comparative datasets on body composition at birth among healthy, live‐born preterm infants are lacking.
Disparity map estimation uses block matching algorithm and bilateral filter

This paper proposes a new disparity map algorithm which uses block matching and edge-preserving filter. The Sum of Absolute Differences (SAD) algorithm uses block matching technique which produces accurate results on the disparity map for the textured regions. However, this algorithm is sensitive to low texture areas and high noise on images with high different brightness and contrast of images. To get over these problems, the proposed algorithm utilizes edge-preserving filter which is known as Bilateral Filter (BF). The BF kernel well-recovered low texture areas which is able to reduce noise and sharpen the images. Additionally, BF is strong against the distortions due to high brightness and contrast. The proposed work in this paper produces accurate results and performs much better compared to some established algorithms based on the quantitative and qualitative measurements using standard stereo benchmarking evaluation from the Middlebury.
A novel AC-AC series voltage compensator without large energy storage elements and using partial power conversion

Voltage faults and harmonics are some of the main problems in the modern electric power distribution system. Traditional solutions are proved to have several drawbacks. In this paper, a novel AC-AC series voltage compensator without large energy storage elements is proposed to deal with the above voltage problems in the power system, which only requires partial power conversion. In addition, only two bi-directional switches are required in each phase, which reduces the cost. Furthermore, the IGBT bridge-type module is available to realize the bi-directional switch. The system configuration is introduced with the operation principle and the control method of voltage regulation in detail. The system is simulated by MATLAB/Simulink to verify the principle of the proposed device. The experiments are carried out based on a 30kW prototype. All the results show that the voltage problems can be solved effectively by the proposed compensator.
Report on the Foundations of Quantitative Information Flow Research Seminar in Cryptography Jake

This report, prepared for the course Research Seminar in Cryptography provides an introduction to the concept of quantitative information flow and an overview of recent developments in the field based on the work of Geoffrey Smith. Previously defined metrics are not effective in measuring information flow against certain threat models, specifically when an adversary has a high probability of learning information in one try. Weaknesses of previously defined metrics based on Shannon entropy and mutual information are discussed and a more recent measure based on min-entropy that provides refined security guarantees is presented.
Importance of SERCA2a on early isolated diastolic dysfunction induced by supravalvular aortic stenosis in rats

Cardiac remodeling is defined as changes in shape and function of the heart in response to aggression (pressure overload). The sarcoplasmic reticulum calcium ATPase cardiac isoform 2a (SERCA2a) is a known factor that influences function. A wide spectrum of studies report a decrease in SERCA2a in heart failure, but none evaluate it's the role in early isolated diastolic dysfunction in supravalvular aortic stenosis (AoS). Our hypothesis was that SERCA2a participates in such dysfunction. Thirty-day-old male Wistar rats (60-80 g) were divided into AoS and Sham groups, which were submitted to surgery with or without aorta clipping, respectively. After 6 weeks, the animals were submitted to echocardiogram and functional analysis by isolated papillary muscle (IPM) in basal condition, hypoxia, and SERCA2a blockage with cyclopiazonic acid at calcium concentrations of 0.5, 1.5, and 2.5 mM. Western-blot analyses were used for SERCA2a and phospholamban detection. Data analysis was carried out with Student's t-test and ANOVA. AoS enhanced left atrium and E and A wave ratio, with preserved ejection fraction. Basal condition in IPM showed similar increases in developed tension (DT) and resting tension (RT) in AoS, and hypoxia was similar between groups. After cyclopiazonic acid blockage, final DT was equally decreased and RT was similar between groups, but the speed of relaxation was decreased in the AoS group. Western-blot was uniform in all evaluations. The hypothesis was confirmed, since functional parameters regarding SERCA2a were changed in the AoS group.
Stopping rules for clinical trials incorporating clinical opinion.

A method is described of eliciting a 'range of equivalence', i.e. a range of differences between two treatments over which a group of clinical trial participants would have no clear preference for either treatment. This range of equivalence is then incorporated into a formal stopping rule for the trial using an extension of the group sequential design. Tables for the implementation of the design are presented. The method is discussed in the context of other sequential-trial designs.
Firing and training costs and labour market segmentation

of the thesis This dissertation consists of three essays on the labour market impact of firing and training costs. The modelling framework resorts to the search and matching literature. The first chapter introduces firing costs, both linear and non-linear, in a new Keynesian model, analysing business cycle effects for different wage rigidity degrees. The second chapter adds training costs to firing costs in a model of a segmented labour market, accessing the interaction between these two features and the skill composition of the labour force. Finally, the third chapter analyses empirically some of the issues raised in the second chapter.
Theoretical analysis for the reflection of a focused ultrasonic beam from a fluid–solid interface

A theoretical study of the reflection of focused acoustic beams from a fluid–solid interface is presented. The incident field is defined by a Gaussian velocity distribution along a plane emitter. The reflected field is described through its pressure field in a region not restricted to the interface. Nonspecular phenomena were exhibited at any angle of incidence by means of short wave asymptotic analysis. In particular, for incidence near the Rayleigh angle, a distortion of a part of the caustic of the reflected beam including lateral and axial displacements of the focal point is observed.
Effectiveness of Donor Natural Killer Cell Alloreactivity in Mismatched Hematopoietic Transplants

T cells that accompany allogeneic hematopoietic grafts for treating leukemia enhance engraftment and mediate the graft-versus-leukemia effect. Unfortunately, alloreactive T cells also cause graft-versus-host disease (GVHD). T cell depletion prevents GVHD but increases the risk of graft rejection and leukemic relapse. In human transplants, we show that donor-versus-recipient natural killer (NK)–cell alloreactivity could eliminate leukemia relapse and graft rejection and protect patients against GVHD. In mice, the pretransplant infusion of alloreactive NK cells obviated the need for high-intensity conditioning and reduced GVHD. NK cell alloreactivity may thus provide a powerful tool for enhancing the efficacy and safety of allogeneic hematopoietic transplantation.
Collection by a simple bag method and the function of granulocytes in granulocyte transfusion

Granulocyte transfusion is effective for treating some intractable infections. We have recently developed a simple bag method for collecting granulocytes without using apheresis. A recombinant human granulocyte colony-stimulating factor (G-CSF) (50,100,200, and 400 μastim) was administered to 5 healthy male adult volunteers. The quantity and quality of the collected granulocytes were evaluated. The G-CSF dose proportionally increased the collected neutrophil count. The count of collected neutrophils correlated strongly with the count before collection (r2 = 0.684; P < .001). The neutrophil counts collected from 200 mL whole blood were 0.90 X 109,1.68 X 109,2.40 X 109, and 2.99 X 109 at 50,100,200, and 400 μg G-CSF, respectively. There was no significant difference in neutrophil counts between the 200-μg and 400-μg doses. Concerning granulocyte functions, active oxygen production and phagocytic capacity were not affected by irradiation with 15 Gy. Transient arthralgia occurred in 2 subjects. A single administration of 200 μg G-CSF enabled the collection of large quantities of granulocytes by the bag method. We consider that the collection of granulocytes by the bag method from 400 mL of whole blood drawn twice can theoretically provide 3 X 108/kg of granulocytes for treating children weighing less than 30 kg.
Introduction and metabolism of pentose and hexose phosphates in permeabilized morris hepatoma 5123TC cells

Metabolism of arabinose 5‐P, ribose 5‐P and glucose 6‐P in permeabilized and resealed Morris hepatoma 5123TC cells was investigated by measuring the contribution of these compounds to nucleic acid biosynthesis. The level of [14C]‐arabinose (non‐phosphorylated) incorporation into nucleic acids was slight, presumably due to the low activity of the transport system or the absence or low activity of a specific ‘kinase’ enzyme. The permeabilizing procedure involved the brief treatment of Morris hepatoma 5123TC cells with lysolecithin and resulted in a cell population which was permeable to charged compounds i.e. Sugar phosphates and nucleotides, that otherwise could not cross the plasma membrane. The permeabilized (and resealed cells) retained normal cellular morphology and intactness of specific organelles as judged by the maintenance of functional properties. Following permeabilization, these cells resealed when transferred back to normal growth medium, and continued to divide and increase at the same rates as control non‐permeabilized cell cultures. The permeabilized cells incorporated deoxyribonucleotides ([methyl ‐3H]‐TTP) into DNA at a linear rate of 0·047 nmol per 107 cells min−1, representing 90–100 per cent of the DNA synthesis rate in vivo. The permeabilization technique, when coupled with procedures to establish cell synchrony, permitted the comparative estimate of the contributions of [14C]‐labelled arabinose 5‐P, ribose 5‐P and glucose 6‐P to RNA, DNA, amino acids, CO2, lactate and sugar mono‐ and bisphosphates. The percentage of [14C]‐isotope incorporated into total nucleic acids by these three labelled sugar phosphates were 2·3, 4·9 and 6·3 respectively. Possible reasons for the lower incorporation of 14C from arabinose 5‐P are given. The results are consistent with the proposal that arabinose 5‐P, an intermediate of the L‐type pentose pathway activity of 5123TC cells, was incorporated into nucleic acids by its interconversion with ribulose 5‐P and ribose 5‐P and thus into PRPP. This study represents the first report of sugar phosphate as opposed to free sugar metabolism by tumour cells in culture.
