AbstractChildren from high‐risk environments are more likely to experience problems in development. Many difficulties are linked to early experiences in the context of the emerging attachment relationship. Over the past 20 years, our group has collaborated with government agencies to develop and implement an attachment‐based video‐feedback intervention strategy (AVI) that targets parental sensitivity and attachment. This case study presents the manner in which a young mother and her 6‐month‐old son experienced AVI. The study shows how the absence of maternal sensitivity and responsiveness to infant signals, difficulties in helping the child regulate affect, and problems in autonomy support are addressed via eight semi‐structured mentoring visits. Discussion focuses on how AVI may be a helpful addition to primary prevention programs.

AbstractThe influx of non‐European immigrants since 1965 ushered the development and use of acculturation measures in immigrant health studies. A Short Acculturation Scale for Filipino Americans (ASASFA) represents a validated, unidirectional ethnic‐specific measure used with first‐generation FAs. ASASFA's psychometric properties with adult U.S.‐born children—the second generation—remain unexplored. This study determined (a) the factor structure of ASASFA with adult U.S.‐born FAs and (b) the predictors of their acculturation scores. A secondary analysis was conducted on ASASFA data from a mental health survey of 116 U.S.‐born FAs. Exploratory factor and parallel analyses showed a two‐factor solution: language use and preference (Factor 1) and ethnic social relations (Factor 2). Ordinary least squares regression indicated gender and ethnic self‐identification predict Factor 1 scores; self‐identification solely predicts Factor 2 scores. Results demonstrate ASASFA's validity and parsimony, supporting its use in FA health studies when lengthy bidirectional acculturation measures become impractical.

AbstractBackgroundSkeletal muscle is characterized by an efficient regeneration potential that is often impaired during myopathies. Understanding the molecular players involved in muscle homeostasis and regeneration could help to find new therapies against muscle degenerative disorders. Previous studies revealed that the Ser/Thr kinase p21 protein‐activated kinase 1 (Pak1) was specifically down‐regulated in the atrophying gastrocnemius of Yoshida hepatoma‐bearing rats. In this study, we evaluated the role of group I Paks during cancer‐related atrophy and muscle regeneration.MethodsWe examined Pak1 expression levels in the mouse Tibialis Anterior muscles during cancer cachexia induced by grafting colon adenocarcinoma C26 cells and in vitro by dexamethasone treatment. We investigated whether the overexpression of Pak1 counteracts muscle wasting in C26‐bearing mice and in vitro also during interleukin‐6 (IL6)‐induced or dexamethasone‐induced C2C12 atrophy. Moreover, we analysed the involvement of group I Paks on myogenic differentiation in vivo and in vitro using the group I chemical inhibitor IPA‐3.ResultsWe found that Pak1 expression levels are reduced during cancer‐induced cachexia in the Tibialis Anterior muscles of colon adenocarcinoma C26‐bearing mice and in vitro during dexamethasone‐induced myotube atrophy. Electroporation of muscles of C26‐bearing mice with plasmids directing the synthesis of PAK1 preserves fiber size in cachectic muscles by restraining the expression of atrogin‐1 and MuRF1 and possibly by inducing myogenin expression. Consistently, the overexpression of PAK1 reduces the dexamethasone‐induced expression of MuRF1 in myotubes and increases the phospho‐FOXO3/FOXO3 ratio. Interestingly, the ectopic expression of PAK1 counteracts atrophy in vitro by restraining the IL6‐Stat3 signalling pathway measured in luciferase‐based assays and by reducing rates of protein degradation in atrophying myotubes exposed to IL6. On the other hand, we observed that the inhibition of group I Paks has no effect on myotube atrophy in vitro and is associated with impaired muscle regeneration in vivo and in vitro. In fact, we found that mice treated with the group I inhibitor IPA‐3 display a delayed recovery from cardiotoxin‐induced muscle injury. This is consistent with in vitro experiments showing that IPA‐3 impairs myogenin expression and myotube formation in vessel‐associated myogenic progenitors, C2C12 myoblasts, and satellite cells. Finally, we observed that IPA‐3 reduces p38α/β phosphorylation that is required to proceed through various stages of satellite cells differentiation: activation, asymmetric division, and ultimately myotube formation.ConclusionsOur data provide novel evidence that is consistent with group I Paks playing a central role in the regulation of muscle homeostasis, atrophy and myogenesis.
Topical rifampin powder for orthopedic trauma part I: Rifampin powder reduces recalcitrant infection in a delayed treatment musculoskeletal trauma model

Published: May 2018

ABSTRACTOpen fractures become infected despite meticulous debridement and care. Locally applied antibiotics, commonly embedded in polymethylmethacrylate, deliver high doses of drug directly to the fracture site. Direct application of antibiotic powder, which is being applied prophylactically in spine surgery, is a recent interest in the trauma sector, where bacterial biofilms are more prevalent. Traditional antibiotics, such as vancomycin, are poor performers against bacterial biofilms thus are ineffective in delayed treatment. Rifampin is an effective eradicator of Staphylococcal biofilms. Here, a rat model of musculoskeletal trauma was used to evaluate the utility of locally applied rifampin powder for reducing established orthopedic Staphylococcal infections in a delayed treatment scenario that previously indicated the limited use of local vancomycin. By applying rifampin powder directly to the contaminated segmental defect, the number of bacteria, as well as clinical indications of infection, were significantly reduced compared to vancomycin and daptomycin. Considering the Infectious Disease Society of America's recommendation to use rifampin in combination with another antibiotic to reduce the onset of rifampin resistance, rifampin powder was also applied in combination with vancomycin or daptomycin with insignificant changes in eradication performance. No indications of rifampin resistance were identified. Clinical Significance: The use of locally applied rifampin is a promising therapy for mature and tolerant musculoskeletal infections.

ABSTRACTThe study sought to determine the association between gait biomechanics (vertical ground reaction force [vGRF], vGRF loading rate [vGRF‐LR]) collected 6 months following anterior cruciate ligament reconstruction (ACLR) with patient‐reported outcomes at 12 months following ACLR. Walking gait biomechanics and all subsections of the Knee Injury and Osteoarthritis Outcomes Score (KOOS) were collected at 6 and 12 months following ACLR, respectively, in 25 individuals with a unilateral ACLR. Peak vGRF and peak instantaneous vGRF‐LR were extracted from the first 50% of the stance phase. Limb symmetry indices (LSI) were used to normalize outcomes in the ACLR limb to that of the uninjured limb (ACLR/uninjured). Linear regression analyses were used to determine associations between biomechanical outcomes and KOOS while accounting for walking speed. Receiver operator characteristic curves were used to determine the accuracy of 6‐month biomechanical outcomes for identifying individuals with acceptable patient‐reported outcomes, using previously defined KOOS cut‐off scores, 12 months post‐ACLR. Individuals with lower peak vGRF LSI 6 months post‐ACLR demonstrated worse patient‐reported outcomes (KOOS Pain, Activities of Daily life, Sport and Recreation, Quality of Life) at the 12‐month exam. A peak vGRF LSI ≥0.99 6 months following ACLR associated with 13.33× higher odds of reporting acceptable patient‐reported outcomes 12 months post‐ACLR. Lesser peak vGRF LSI during walking at 6‐months post‐ACLR may be a critical indicator of worse future patient‐reported outcomes. Clinical significance achieving early symmetrical lower extremity loading and minimizing under‐loading of the ACLR limb during walking may be a potential therapeutic target for improving patient‐reported outcomes post‐ACLR. © 2018 Orthopaedic Research Society.

Published: May 2018

AbstractCoherent anti‐Stokes Raman scattering is shown to provide a versatile spectroscopic protocol for the optical interrogation of broadband quantum memories based on long‐lived coherent phonons in solids. In our scheme of coherent anti‐Stokes Raman scattering‐interrogated broadband quantum memory, a frequency‐tunable Stokes field, delivered by dispersion‐ and nonlinearity‐engineered photonic‐crystal fiber, maps the broadband pump wave packet into a memory based on coherently driven optical phonons of diamonds. The probe field is then applied with a variable delay time to read out the coherence driven by the pump and Stokes fields, giving rise to an anti‐Stokes signal, which serves to report the state of the phonon memory.
Influence of Cationic Surfactants on the Crystallization of Cis‐ and Trans‐Isomers

Published: May 2018

AbstractThe crystals of cis‐ and trans‐isomers present in principle similar chemical groups on their respective crystal faces. Here, the crystallization of cis‐ and trans‐isomers (maleic acid and fumaric acid) in an aqueous solution containing cationic surfactants with different hydrophobic chains (the long hydrophobic chains of dodecyltrimethylammonium bromide < cetyltrimethylammonium bromide < trimethylstearylammonium bromide) was investigated. Results showed that the surfactants presented different effects on the crystallization of cis‐ and trans‐isomers. For trans‐isomers (fumaric acid), the surfactants with longer hydrophobic chains or higher solution concentrations will favor a wider metastable zone width (MZW) and a greater morphology change. By contrast, both the MZW and morphology development of cis‐isomers (maleic acid) were not affected by these surfactants. The chemical groups on crystal faces, surface grooves, and molecular polarity were compared to reveal the different influences of surfactants on the crystallization of cis‐ and trans‐isomers.
Modelling crosstalk through common semiconductor layers in AMOLED displays

Published: May 2018

AbstractHigh pixel density displays are demanded for active matrix organic light‐emitting diode displays (AMOLED) in applications such as virtual reality headsets, micro‐displays, and high‐end smartphones. Parasitic emission from non‐addressed neighboring pixels (crosstalk) is a common problem in such high pixel density AMOLED, and this crosstalk becomes more severe as the pixel density and fill ratio of the display increases. One of the causes of crosstalk is parasitic currents that travel through common organic semiconductor layers. In this paper, we model and quantify the pixel crosstalk using a 2 + 1D finite element model that is based on the conductivity of the common layer and the luminance–current–voltage curves of the subpixels as measured input parameters. We assess the effect of crosstalk on the pixel current, observed color, and luminance. The 2 + 1D model limits the number of degrees of freedom so that calculations on a standard personal computer are feasible.
Movement patterns of white‐tailed sea eagles near wind turbines
Authors: Krone Oliver , Treu Gabriele 
Published: May 2018

ABSTRACTWhite‐tailed sea eagles (Haliaeetus albicilla) exhibit one of the highest mortality rates at wind power plants (WPPs) among raptor species in Europe, but data on circumstances of collision and behavioral response to WPPs are scarce. We analyzed the effect of WPPs on movement patterns of sea eagles in Germany with satellite telemetry. We analyzed ranging behavior and environmental parameters that influence the behavioral flight response to WPPs using multiple regression models. During 2003 through 2009 we radio‐tracked 25 white‐tailed sea eagles in northern Germany (8 territorial, 7 non‐territorial, 10 young eagles marked as nestlings). Mean home range sizes of territorial eagles varied with individuals tracked and the estimation method applied, ranging from 2.7 km2 to 669.7 km2. Sex or breeding status did not influence home range size. Ranging behavior varied between individuals and was correlated with habitat quality (i.e., nest distance to nearest water source and to anthropgogenic structure) and weather conditions. Among the 9 territorial eagles, only 1 individual resided within the officially proposed 3‐km minimum safety distance between nest and planned WPP. However, others frequently moved >3 km away from their nests, leaving the proposed safety area. One eagle inhabiting a territory within intensively cultivated landscape frequently approached a WPP and did not alter its movement patterns near the WPP compared to control areas. We identified several features visited by the eagles (e.g., perches, small lakes). To mitigate the collision risk of eagles, the recommended safety radius of 3 km between nest and WPP should become an international standard with a safe flight corridor to feeding grounds. To avoid frequent collisions at the population scale with WPPs, it is important to construct WPPs only outside the main distribution areas of white‐tailed sea eagles. © 2018 The Wildlife Society.
Geomorphological and sedimentological indicators of land degradation (Meghalaya Plateau, NE India)

Published: May 2018

AbstractReplacement of forests by cultivation in hilly regions can dramatically increase overland flow and soil erosion, frequently resulting in land degradation. This study aimed to determine the impact of long‐term human activity and natural geomorphic processes in land degradation of 2 catchments located in the Meghalaya Plateau in northeast India. Both catchments are built by deeply weathered granites with hilly topography but have contrasting land uses. Forested catchment (1.5 ha) is covered by natural deciduous forest, whereas deforested catchment (3.5 ha) is affected by slash and burn cultivation and boulder extraction. Detailed geomorphological mapping and sediment pattern analysis revealed a complex anthropogenic role in land degradation. Human activity contributes directly to the creation of new landforms in the deforested catchment and indirectly by influencing the course and intensity of geomorphological processes, masking the pre‐existing natural relief. Discontinuous agricultural terraces, zero‐order valleys, and furrows created coexisting cascade system and direct connectivity of water and sediment transport within the same slope. Higher content of fine‐grained material and lower content of boulders in the deforested catchment reflect overlapping of 2 traditional occupations of the local population: agriculture and selective boulders extraction, respectively. Human activity combined with accelerated erosion of abundant weathered material led to the transformation of incised valley bottom into flat accumulation plain as well as the extension and aggradation of the alluvial fan. This process increased the proportion of flat landforms favourable for cultivating the deforested catchment under growing population pressure.

Published: May 2018

AbstractThe Akhmediev breather has attracted considerable attention over the past decades in various fields such as hydrodynamics, plasma physics, and nonlinear optics because of its wide applications and its importance in understanding nonlinear coherent phenomena. Here, we introduce optomechanical arrays as an integrated platform to observe both photonic and phononic Akhmediev breathers, with remarkable functionality for readout and control, complementing existing research on hydrodynamic and plasma systems. Our results pave a path toward reconfigurable nanophotonic and phononic networks, and may enable a new class of devices in signal processing and on‐chip nonlinear dynamical systems.

Published: May 2018

BackgroundGreen, blue, and purple tattoo pigments are often the colors most resistant to laser removal. Recently, the first ever production picosecond‐domain laser with a 785 nm wavelength was developed to improve the rate of clearance of green, blue, and purple tattoo inks.MethodsTwenty‐two tattoos from 15 subjects with skin phototypes II–IV were enrolled in the study. A total of four treatments were administered using a single 785 nm picosecond‐domain laser wavelength. Blinded assessment of digital, cross‐polarized photographs taken approximately 8 weeks following the last treatment was performed using an 11‐point clearance scale.ResultsFourteen subjects with 21 tattoos completed all study visits. The 21 tattoos contained the following pigments: black (n = 15), green (n = 13), blue (n = 8), yellow (n = 5), purple (n = 4), and red (n = 3). Treatments were performed with a 2‐4‐mm beam diameter and fluences ranging from 1.1 to 3.1 J/cm2. Blinded assessment of photographs found 85%, 81%, 74%, 61%, 11%, and 5% clearance from baseline photos for purple, blue, green, black, red, and yellow pigments, respectively. Treatments were well tolerated with typical erythema, edema and one case of pinpoint bleeding. No scarring was noted.ConclusionThis first study of a new 785 nm picosecond‐domain laser demonstrates safe and effective removal of multicolor tattoos. Although clearance was shown for a multitude of colors including black, the 785 nm laser wavelength has special affinity to purple, blue and green tattoo pigments. Lasers Surg.

Places as authentic consumption contexts
Authors: Spielmann Nathalie , Babin Barry J. , Manthiou Aikaterini 
Published: May 2018

AbstractConsumers build social capital through purposeful consumer–place interactions. Airbnb claims that consumers want to “experience a place like [they] live there.” Previous research concentrates primarily on authenticity of objects, brands, and people, with limited development of place authenticity as a concept. But place authenticity represents an increasingly important marketing concept as consumers today, particularly millennials (Schulz, P. (2015, August 8). Not just millennials: Consumers want experiences, not things. Adage. Retrieved from https://adage.com/article/digitalnext/consumers-experiences-things/299994/), value experience over “stuff.” Authenticity provides an important place characteristic that if perceived, potentially unlocks a truly valuable consumer experience. Consequently, the research presented here develops an auxiliary theory of place authenticity (PA). The theory proposes a second‐order factor indicated by three coordinate subdimensions. Phase I of the research consists of five studies that develop PA, explore its dimensionality, and confirm the PA scale's construct validity. Phase II of the research involves a sixth study, which examines a set of hypotheses that begin to establish PA's nomological net. The results shed light on the psychology by which consumers extract value from experience and into ways marketing efforts can build effective place–value propositions.

IntroductionThe aim of this study was to evaluate the behavior of a penalized‐likelihood image reconstruction method (Q.Clear) under different count statistics and lesion‐to‐background ratios (LBR) on a BGO scanner, in order to obtain an optimum penalization factor (β value) to study and optimize for different acquisition protocols and clinical goals.MethodsBoth phantom and patient images were evaluated. Data from an image quality phantom were acquired using different Lesion‐to‐Background ratios and acquisition times. Then, each series of the phantom was reconstructed using β values between 50 and 500, at intervals of 50. Hot and cold contrasts were obtained, as well as background variability and contrast‐to‐noise ratio (CNR). Fifteen 18F‐FDG patients (five brain scans and 10 torso acquisitions) were acquired and reconstructed using the same β values as in the phantom reconstructions. From each lesion in the torso acquisition, noise, contrast, and signal‐to‐noise ratio (SNR) were computed. Image quality was assessed by two different nuclear medicine physicians. Additionally, the behaviors of 12 different textural indices were studied over 20 different lesions.ResultsQ.Clear quantification and optimization in patient studies depends on the activity concentration as well as on the lesion size. In the studied range, an increase on β is translated in a decrease in lesion contrast and noise. The net product is an overall increase in the SNR, presenting a tendency to a steady value similar to the CNR in phantom data. As the activity concentration or the sphere size increase the optimal β increases, similar results are obtained from clinical data. From the subjective quality assessment, the optimal β value for torso scans is in a range between 300 and 400, and from 100 to 200 for brain scans. For the recommended torso β values, texture indices present coefficients of variation below 10%.ConclusionsOur phantom and patients demonstrate that improvement of CNR and SNR of Q.Clear algorithm which depends on the studied conditions and the penalization factor. Using the Q.Clear reconstruction algorithm in a BGO scanner, a β value of 350 and 200 appears to be the optimal value for 18F‐FDG oncology and brain PET/CT, respectively.
