Photonics Packaging Made Visible
Authors: Geuzebroek Douwe , Dekker Ronald , van Dijk Paul 
Published: December 2017

AbstractPhotonic integrated circuit technology for visible light enables new applications which are not possible to realize with existing discrete components [1]. As PIC technology has a more mature status in the infrared wavelength range around 1550 nm for telecom applications, certain assembly and packaging standards have already been implemented. However, the broad application scope, ranging, for instance, from confocal microscopy to biosensors and display applications, requires a different set of packaging technologies in creating the PIC into a robust and usable product. In this article, we describe – via a set of application examples different options – on how interfaces can be made to PICs for visible light which meets the requirements for these emerging applications.

The protective role of teacher–student relationships against peer victimization and psychosocial distress
Authors: Sulkowski Michael L. , Simmons Jessica 
Published: December 2017

AbstractThis study examined whether teacher–student relationships protect against peer victimization and its negative psychosocial effects (i.e., depression, anxiety, and stress). Additionally, the influence of teacher–student relationships, peer relationships, and students’ perceptions of school order and discipline was investigated as these variables were expected to be negatively related to the former. Data were collected from high school‐aged adolescents (N = 539; 51% female) in the U.S. Southwest. Study results indicate that teacher–student relationships buffered against experiencing psychosocial distress associated with peer victimization. Although positive teacher–student relationships, peer relationships, and students’ perceptions of school order and discipline all were negatively associated with peer victimization and psychosocial distress, teacher–student relationships were robustly related to peer victimization and psychosocial distress over the influence of the previous variables. In other words, as a key study finding, teacher–student relationships may reduce the impact of peer victimization by mitigating its negative psychosocial effects in a robust yet relatively unexplored way. Therefore, although more research is needed, fostering positive teacher–student relationships might be an effective way to reduce peer victimization as well as its negative effects.
Promoting sisterhood: The impact of a culturally focused program to address verbally aggressive behaviors in Black girls
Authors: Aston Candice , Graves Scott L. , McGoey Kara , Lovelace Temple , Townsend Tiffany 
Published: December 2017

AbstractNew estimates report that Black girls are facing an educational crisis with regard to disproportionate disciplinary practices and academics. To date, there has been very limited research with regard to school‐based interventions that have been designed to help Black girls explore both their cultural and gender identity. This is problematic because Black girls are constantly faced with the task of disproving negative characterizations (i.e., angry, loud, and aggressive) and advocating for equitable treatment from teachers and school administrators. These negative characteristics often translate to lower academic expectations, harsher punishments, and juvenile justice involvement. To address this problem, a single‐subject study was conducted to investigate the effectiveness of implementing an 8‐week cultural‐empowerment program based on the Sisters of Nia curriculum. Results based on visual analysis, percentage of nonoverlapping data, and Tau‐U all show that the Sisters of Nia intervention led to a significant reduction in verbally aggressive behavior for all four participants. These findings serve as further support to incorporate culturally based interventions at the school level.
Training in strength‐based intervention and assessment methodologies in APA‐accredited psychology programs
Authors: Nichols Kayla , Graves Scott L. 
Published: December 2017

AbstractThe importance of identifying and building on individual strengths has been a key component of many psychoeducational theories and modalities focused on developing interventions. However, program training in this growing area is not well known. As such, this is the first study designed to ascertain the American Psychological Association–accredited psychology programs strength‐based training practices. Results show that a majority of faculty (83.9% of school psychology, 48.4% of counseling psychology, and 50.0% clinical psychology) thinks that strength‐based practices are very beneficial; however, training in these methodologies has not kept pace with faculty beliefs, with over 60% of faculty not being familiar with strength‐based manualized interventions. Implications are discussed in terms of improving the research base to alleviate trainers’ concerns and challenges that impede their implementation of dual models of mental health in their psychology programs.

Published: December 2017

ABSTRACTA series of ferrocene‐terminated hyperbranched polyimides (HBPI‐Fcs) were synthesized from a tetra‐amine, bis(4‐(3,5‐bis (4‐amino‐2‐(trifluoromethyl) phenoxy) phenoxy) phenyl) methanon, and various dianhydrides, followed by termination with (4‐amino) phenyl ferrocene. All the HBPI‐Fcs possessed good organo‐solubility and high thermal stability. The devices based on HBPI‐Fcs exhibited bipolar and nonvolatile write‐once‐read‐many times (WORM) memory performance with various threshold voltages and the same ON/OFF current ratio of 104. Moreover, the devices possessed excellent bistability under a constant bias of −1.00 V during a test period of 104 s. The different charge trapping ability of the electron‐accepting moiety endowed the devices with different the threshold voltages. Mechanism analysis showed that the switching behavior was dominated by the charge trapping effect and the charge transfer was well fitted with the space‐current‐limited‐current (SCLC) and ohmic model. © 2017 Wiley Periodicals, Inc.

Careful investigation of the hydrosilylation of olefins at poly(ethylene glycol) chain ends and development of a new silyl hydride to avoid side reactions
Authors: Shin Hyunseo , Moon Bongjin 
Published: December 2017

ABSTRACTHydrosilylation of olefin groups at poly(ethylene glycol) chain ends catalyzed by Karstedt catalyst often results in undesired side reactions such as olefin isomerization, hydrogenation, and dehydrosilylation. Since unwanted polymers obtained by side reactions deteriorate the quality of end‐functional polymers, maximizing the hydrosilylation efficiency at polymer chain ends becomes crucial. After careful investigation of the factors that govern side reactions under various conditions, it was related that the short lifetime of the unstable Pt catalyst intermediate led to the formation of more side products under the inherently dilute conditions for polymers. Based on these results, two new chelating hydrosilylation reagents, tris(2‐methoxyethoxy)silane (5) and 2,10‐dimethyl‐3,6,9‐trioxa‐2,10‐disilaundecane (6), have been developed. It was demonstrated that the hydrosilylation efficiency at polymer chain ends was significantly increased by employing the internally coordinating hydrosilane 5. In addition, employment of the internally coordinating disilane species 6 in an addition polymerization with 1,5‐hexadiene by hydrosilylation reaction yielded a polymer with high molecular weight (Mn = 9300 g/mol), which was significantly higher than that (Mn = 2600 g/mol) of the corresponding polymer obtained with non‐chelating dihydrosilane, 1,1,3,3‐tetramethyldisiloxane. © 2017 Wiley Periodicals, Inc.

AbstractObjectiveThe purpose of this study was to describe distressed and underprepared family caregiver's use of and interest in formal support services (eg, professional counseling, education, organizational assistance).MethodCross‐sectional mail survey conducted in communities of 8 cancer centers in Tennessee, Alabama, and Florida (response rate: 42%). Family caregivers of Medicare beneficiaries with pancreatic, lung, brain, ovarian, head and neck, hematologic, and stage IV cancers reported support service use and completed validated measures of depression, anxiety, burden, preparedness, and health.ResultsCaregivers (n = 294) were on average age 65 years and mostly female (73%), White (91%), and care recipients' spouse/partner (60%); patients averaged 75 years were majority male (54%) with lung cancer (39%). Thirty‐two percent of caregivers reported accessing services while 28% were “mostly” or “extremely” interested. Thirty‐five percent of caregivers with high depressive symptoms (n = 122), 33% with high anxiety symptoms (n = 100), and 25% of those in the lowest quartile of preparedness (n = 77) accessed services. Thirty‐eight percent of those with high depressive symptoms, 47% with high anxiety symptoms, and 36% in the lowest quartile of preparedness were “mostly” or “extremely” interested in receiving services. Being interested in support services was significantly associated with being a minority, shorter durations of caregiving, and with higher stress burden.ConclusionsA large proportion of family caregivers, including those experiencing depression and anxiety symptoms and who were underprepared, are not using formal support services but have a strong interest in services. Strategies to increase service use may include targeting distressed caregivers early in their caregiving experience.

AbstractObjectiveTo determine demographic and clinical correlates of accelerometer assessed physical activity and sedentary time among a population‐based sample of lung cancer survivors.MethodsLung cancer survivors in Southern Alberta, Canada (N = 527) were invited to complete a mailed survey assessing socio‐demographics and wear an Actigraph® GT3X+ accelerometer for 7 days. Average daily minutes of physical activity and sedentary time were derived from the accelerometer data. Accelerometer data were processed using standard Freedson cutpoints, and correlates of physical activity and sedentary time were determined with linear regression.ResultsA total of 127 lung cancer survivors participated (mean age = 71 years), for a 24% response rate. Moderate‐to‐vigorous physical activity was negatively associated with being >60 years of age (β = −7.4, CI: −14.7, −0.10). Moderate‐to‐vigorous physical activity accumulated in 10‐minute bouts was associated with receiving surgery and adjuvant chemotherapy (β = 9.1, CI: 2.1, 16.1). Sedentary time was associated with being >60 years of age (β = 32.4, CI: 3.1, 61.7), smoking (β = 63.9, CI: 22.5, 105.4), and being overweight/obese (β = 28.6, CI: 6.4, 50.1).ConclusionAge, smoking history, and body mass index emerged as correlates of accelerometer assessed light, moderate, and vigorous physical activity, and sedentary time among lung cancer survivors.Implications for Cancer SurvivorsIdentifying correlates of physical activity and sedentary time may aid in the development of targeted behavioral interventions for this population.

AbstractA biocompatible silk fibroin‐based carbon quantum dot (SF‐CQD) is first synthesized under microwave irradiation for a short time. This fast and environmentally safe technique produce well‐defined nanosized SF‐CQDs. The SF‐CQDs have good crystallinity, a strong emission peak in the blue‐color region, high quantum yield, and the potential for modification with various functional groups on the surface. These SF‐CQDs demonstrate stable emission, good water dispersity, low toxicity, and good biocompatibility. These properties show the great potential of these SF‐CQDs for use in biomedical applications including bioimaging, biosensing, and drug delivery systems.

AbstractThe construction of high‐performance nanotheranostic agent with Food and Drug Administration (FDA)‐approved materials for efficient treatment of breast cancer is still of great challenge. This work reports, for the first time, on the elaborate integration of two FDA‐approved materials together to construct a multifunctional core/shell‐structured “nanococktail” for cancer theranostics. The biocompatible Prussian blue nanoparticles with high photothermal‐conversion performance are coated by poly(lactic‐co‐glycolic acid) followed by further surface targeting engineering (folic acid conjugation). The anticancer drug paclitaxel is concurrently encapsulated into the nanocarrier with high efficiency and capacity. Especially, these “nanococktails” act as the desirable contrast agents for photoacoustic/magnetic resonance imaging dual‐mode diagnostic imaging, providing the potential for guidance and monitoring during the therapeutic process, which has been systematically demonstrated both in vitro and in vivo. Importantly, these “nanococktails” have demonstrated their high performance in synergistic in vivo photothermal therapy and chemotherapy against breast cancer tumor xenograft. This work not only provides a high‐performance theranostic “nanococktail” platform for efficient theranostic treatment of cancer but also paves a new way for the integration of various functional moieties together for realizing the specific diagnostic imaging‐guided and synergistic cancer therapy.
Robust Microencapsulated Silicone Oil with a Hybrid Shell for Reducing Propellant Erosion
Authors: Sun Na , Xiao Zhenggang 
Published: December 2017

AbstractA morphologically stable silicon oil microcapsule base polystyrene as shell modified with TiO2 and Si3N4 nanoparticles was synthesized, characterized and applied as an inhibitor for high energy propellant to reduce erosion of gun barrel. The composite microcapsules were obtained by an eco‐friendly method. Embedding heat‐resistant TiO2 and Si3N4 nanoparticles in polystyrene shell enhances the reliability of polymeric shell. The anti‐erosion effect of composite microcapsules for high energy propellant was investigated by using an erosion tester. Results showed that the erosion property of high energy propellant with composite microcapsule was significantly decreased when compared to control sample (without microcapsules). It showed a decrease of 20.6 % in erosion mass when 7 wt.% of composite microcapsules were added to the high energy propellant. Moreover, the anti‐erosion efficiency of composite additives exhibited an increasing trend with the increase of their contents. The pressure and time history confirmed that the composite microcapsules also have ability to adjust the combustion performance of high energy propellants. The developed silicon oil microcapsule shows a potential application for propellant erosion additive.

Published: December 2017

Safe and efficient therapeutic agents for bone diseases are required in natural sources. We previously found that edible seaweed‐derived polysaccharide porphyran exhibited anti‐inflammatory effects through the down regulation of nuclear factor‐κB. The aim of this study was to investigate the availability of porphyran as a therapeutic agent for bone diseases. The effects of porphyran on receptor activator of nuclear factor κB ligand (RANKL)‐induced osteoclastogenesis in RAW264.7 cells were examined. Porphyran suppressed RANKL‐induced osteoclast formation in a concentration‐dependent manner (6.25–50 μg/ml) without any cytotoxic effects. Furthermore, real‐time polymerase chain reaction analyses indicated that porphyran at 50 μg/ml significantly attenuated the RANKL‐induced increase in the mRNA levels of osteoclastogenesis‐related marker genes such as nuclear factor of activated T cells, tartrate‐resistant acid phosphatase, cathepsin K, and matrix metalloproteinase‐9 in RAW264.7 cells. To our knowledge, this is the first report showing that edible‐seaweed‐derived polysaccharide porphyran can suppress RANKL‐induced osteoclastogenesis. Our results suggest that porphyran can be used as a safe therapeutic agent to improve osteoclast‐related pathological conditions.
A novel mechanism for the isomerization of N2O4 and its implication for the reaction with H2O and acid rain formation
Authors: Putikam Raghunath , Lin Ming‐Chang 
Published: December 2017

AbstractWe have discovered, by high‐level quantum‐chemical calculations, a new and predominant isomerization mechanism for N2O4 → ONONO2 via a roaming‐like transition state occurring unimolecularly or bimolecularly during collision with H2O. The new mechanism allows N2O4 to react with H2O with a significantly lower barrier (< 13.1 kcal/mol) than the commonly known tight transition state (∼30‐45 kcal/mol) by concurrent stretching of the NN bond and rotation of one of the NO2 groups to form trans‐ONONO2, which then undergoes a rapid metathetical reaction with H2O in the gas phase and in aqueous solution. The results have a significant implication for the hydrolysis of N2O4 in water to produce HONO and HNO3. Rate constants for the isomerization and hydrolysis reactions have been predicted for atmospheric modeling applications.

Published: December 2017

RationaleLiquid extraction surface analysis (LESA) can be used to generate spatially directed protein identifications in an imaging mass spectrometry (IMS) workflow. This approach involves the use of robotic micro‐extractions coupled to online liquid chromatography (LC). We have characterized the extraction efficiency of this method as well as its ability to identify proteins from a matrix assisted laser/desorption ionization (MALDI) IMS experiment.MethodsProteins and peptides were extracted from transverse sections of a rat brain and sagittal sections of a mouse pup using liquid surface extractions. Extracts were either analyzed by online LC coupled to a high mass resolution Fourier transform ion cyclotron resonance (FTICR) mass spectrometer or collected offline and analyzed by traditional LC/MS methods. Identifications were made using both top‐down and bottom‐up methodologies. MALDI images were acquired on a 15T FTICR mass spectrometer at 125 μm spatial resolution.ResultsRobotic liquid surface extractions are reproducible across various tissue types, providing significantly improved spatial resolution, with respect to extractions, while still allowing for a robust number of protein identifications. A single 2‐μL extract can provide identification of over 14,000 peptides with little sample preparation, increasing throughput for spatially targeted workflows. Surface extractions from tissue were coupled directly to LC to gather spatially relevant proteomics data.ConclusionsRobotic liquid surface extractions can be used to interrogate discrete regions of tissue to provide protein identifications with high throughput, accuracy, and robustness. The direct coupling of tissue surface extractions and LC offers a new and effective approach to provide spatial proteomics data in an imaging experiment.

Published: December 2017

RationaleCarcinogenic o‐methylaniline is one of the banned aromatic amines in azo dyes, but it is very difficult to distinguish it from its noncarcinogenic isomers due to their identical retention time on chromatography and similar mass spectra.MethodsImidization of the isomeric methylanilines was carried out by treatment with benzaldehyde under mild conditions. The formed derivatives were analyzed by gas chromatography/mass spectrometry (GC/MS). Theoretical calculations were carried out on the Gaussian 03 program by using the density functional theory method at the B3LYP/6‐311+G(d,p) level.ResultsImidization of methylanilines occurred easily and gave rise to the corresponding N‐methylbenzylidene benzenamines. The isomeric derivatives were completely separated by GC, and thus the three isomeric methylanilines could be determined simultaneously. Due to the ortho effect, the derivative from o‐methylaniline has a characteristic fragment ion at m/z 118 with a stable bicyclic structure, and it could be easily differentiated from the meta‐ and para‐isomers in electron ionization mass spectrometry.ConclusionsThese results provided a promising solution for simultaneous determination of isomeric methylanilines.
Secure estimation for cyber‐physical systems with adversarial attacks and unknown inputs: An L2‐gain method
Authors: Xie Chun‐Hua , Yang Guang‐Hong 
Published: December 2017

SummaryThis paper investigates the attack‐resilient state estimation problem for linear systems with adversarial attacks and unknown inputs, where the upper bound of the unknown inputs is unknown. It is assumed that the attacker has limited resources and can only manipulate a certain number of sensors. In most of the existing observer design approaches for the systems with unknown inputs even in the absence of attacks, the observer matching condition should be satisfied. To overcome this restriction, a novel switched observer is proposed, where the matched unknown inputs will be completely compensated by means of the outputs and the mismatched part will be suppressed in terms of L2‐gain rejection property. Meanwhile, the observer can provide an attack‐resilient state estimation. Compared with the existing results, the proposed observer can guarantee that the resulting observer error system is stable with unknown input attenuation level γ that can be optimized. Finally, a simulation example of an unmanned ground vehicle is provided to show the effectiveness of the proposed approach.
