Authors: Pietrantoni Zachary , Glance Dorea 
Published: January 2019

The Social Class and Classism Training Questionnaire was developed to assess multicultural competency and training of social class and classism for school counselor trainees (SCTs). The authors analyzed the differences between accreditation status, social class backgrounds, and factors contributing to SCTs’ competence and training. Results showed that socially desirable responding, number of multicultural courses, and training level contributed most to perceived competence and training. This study provides insight into factors influencing SCTs’ competence and training of social class.El Cuestionario de Capacitación en Clase Social y Clasismo fue desarrollado para evaluar la competencia multicultural y capacitación en clase social y clasismo de consejeros escolares en formación (SCT, por sus siglas en inglés). Los autores analizaron las diferencias entre el estado de acreditación, la clase social de origen y otros factores que contribuyen a la competencia y capacitación de los SCT. Los resultados mostraron que las respuestas socialmente deseables, el número de cursos multiculturales y el nivel de capacitación contribuyeron en mayor medida a la percepción de competencia y capacitación. Este estudio ofrece una perspectiva de los factores que influyen en la competencia y capacitación en clase social de los SCT.

BackgroundLate gadolinium enhancement (LGE) imaging was validated for diagnosis and quantification of myocardial infarction (MI). Despite good contrast between scar and normal myocardium, contrast between blood pool and myocardial scar can be limited. Dark blood LGE sequences attempt to overcome this issue.PurposeTo evaluate T1 rho (T1ρ)‐prepared dark blood sequence and compare to blood nulled (BN) phase sensitive inversion recovery (PSIR) and standard myocardium nulled (MN) PSIR for detection and quantification of scar.Study TypeProspective.PopulationThirty patients with prior MI.Field Strength/SequencePatients underwent identical 1.5 T MRI protocols. Following routine LGE imaging, a slice with scar, remote myocardium, and blood pool was selected. PSIR LGE was repeated with inversion time set to MN, to BN, and T1ρ FIDDLE (flow‐independent dark‐blood delayed enhancement) in random order.AssessmentThree observers. Qualitative assessment of confidence scores in scar detection and degree of transmurality. Quantitative assessment of myocardial scar mass (grams), and contrast‐to‐noise ratio (CNR) measurements between scar, blood pool, and myocardium.Statistical TestsRepeated‐measures analysis of variance (ANOVA) with Bonferroni correction, coefficient of variation, and the Cohen κ statistic.ResultsCNRscar‐blood was significantly increased for both BN (27.1 ± 10.4) and T1ρ (30.2 ± 15.1) compared with MN (15.3 ± 8.4 P < 0.001 for both sequences). There was no significant difference in CNRscar‐myo between BN (55.9 ± 17.3) and MN (51.1 ± 17.8 P = 0.512); both had significantly higher CNRscar‐myo compared with the T1ρ (42.6 ± 16.9 P = 0.007 and P = 0.014, respectively). No significant difference in scar size between LGE methods: MN (2.28 ± 1.58 g) BN (2.16 ± 1.57 g) and T1ρ (2.29 ± 2.5 g). Confidence scores were significantly higher for BN (3.87 ± 0.346) compared with MN (3.1 ± 0.76 P < 0.001) and T1ρ (3.20 ± 0.71 P < 0.001).Data ConclusionPSIR with inversion time (TI) set for blood nulling and the T1ρ LGE sequence demonstrated significantly higher scar to blood CNR compared with routine MN. PSIR with TI set for blood nulling demonstrated significantly higher reader confidence scores compared with routine MN and T1ρ LGE, suggesting routine adoption of a BN PSIR approach might be appropriate for LGE imaging.Level of Evidence: 2Technical Efficacy: Stage 2J.

BackgroundBreast magnetic resonance spectroscopy (1H‐MRS) has been largely based on choline metabolites; however, other relevant metabolites can be detected and monitored.PurposeTo investigate whether lipid metabolite concentrations detected with 1H‐MRS can be used for the noninvasive differentiation of benign and malignant breast tumors, differentiation among molecular breast cancer subtypes, and prediction of long‐term survival outcomes.Study TypeRetrospective.SubjectsIn all, 168 women, aged ≥18 years.Field Strength/SequenceDynamic contrast‐enhanced MRI at 1.5 T: sagittal 3D spoiled gradient recalled sequence with fat saturation, flip angle = 10°, repetition time / echo time (TR/TE) = 7.4/4.2 msec, slice thickness = 3.0 mm, field of view (FOV) = 20 cm, and matrix size = 256 × 192. 1H‐MRS: PRESS with TR/TE = 2000/135 msec, water suppression, and 128 scan averages, in addition to 16 reference scans without water suppression.AssessmentMRS quantitative analysis of lipid resonances using the LCModel was performed. Histopathology was the reference standard.Statistical TestsCategorical data were described using absolute numbers and percentages. For metric data, means (plus 95% confidence interval [CI]) and standard deviations as well as median, minimum, and maximum were calculated. Due to skewed data, the latter were more adequate; unpaired Mann–Whitney U‐tests were performed to compare groups without and with Bonferroni correction. ROC analyses were also performed.ResultsThere were 111 malignant and 57 benign lesions. Mean voxel size was 4.4 ± 4.6 cm3. Six lipid metabolite peaks were quantified: L09, L13 + L16, L21 + L23, L28, L41 + L43, and L52 + L53. Malignant lesions showed lower L09, L21 + L23, and L52 + L53 than benign lesions (P = 0.022, 0.027, and 0.0006). Similar results were observed for Luminal A or Luminal A/B vs. other molecular subtypes. At follow‐up, patients were split into two groups based on median values for the six peaks; recurrence‐free survival was significantly different between groups for L09, L21 + L23, and L28 (P = 0.0173, 0.0024, and 0.0045).Data ConclusionQuantitative in vivo 1H‐MRS assessment of lipid metabolism may provide an additional noninvasive imaging biomarker to guide therapeutic decisions in breast cancer.Level of Evidence: 3Technical Efficacy: Stage 2J.

Prediction of mechanical behavior of cartilaginous infant hips in pavlik harness: A subject‐specific simulation study on normal and dysplastic hips

Published: January 2019

ABSTRACTIn dysplastic infant hips undergoing abduction harness treatment, cartilage contact pressure is believed to have a role in therapeutic cartilage remodeling and also in the complication of femoral head avascular necrosis. To improve our understanding of the role of contact pressure in the remodeling and the complication, we modeled cartilage contact pressure in cartilaginous infant hips undergoing Pavlik harness treatment. In subject‐specific finite element modeling, we simulated contact pressure of normal and dysplastic hips in Pavlik harness at 90° flexion and gravity‐induced abduction angles of 40°, 60° and 80°. We demonstrated that morphologies of acetabulum and femoral head both affected contact pressure distributions. The simulations showed that in Pavlik harness, contact pressure was mainly distributed along anterior and posterior acetabulum, leaving the acetabular roof only lightly loaded (normal hip) or unloaded (dysplastic hip). From a mechanobiological perspective, these conditions may contribute to therapeutic remodeling of the joint in Pavlik harness. Furthermore, contact pressure increased with the angle of abduction, until at the extreme abduction angle (80°), the lateral femoral head also contacted the posterior acetabular edge. Contact pressure in this area could contribute to femoral head avascular necrosis by reducing flow in femoral head blood vessels. The contact pressure we simulated can plausibly account for both the therapeutic effects and main adverse effect of abduction harness treatment for developmental dysplasia of the hip. © 2019 Orthopaedic Research Society.

Long‐term effects of vehicular passages on soil carbon sequestration and carbon dioxide emission in a no‐till corn‐soybean rotation on a Crosby silt loam in Central Ohio, USA
Authors: Yadav Gulab Singh , Lal Rattan , Meena Ram Swaroop 
Published: January 2019

AbstractResearch information from a systematic planned study on the effects of vehicular passages and axle load on soil carbon dioxide (CO2) fluxes and soil carbon (C) sequestration under long‐term NT farming is scanty. Therefore, the present study was conducted on an on‐going 20‐year experiment to assess the impacts of variable vehicular passages of a low axle load on soil CO2 emission and soil C sequestration from a no‐till (NT) managed corn (Zea mays L.)–soybean (Glycine max Linneo) rotation in comparison with that a soil under woodlots (soils under natural wooded plantation). The experimental treatment consisted of an empty wagon [0 Mg load for compaction (C‐0; control)] compared with 2 (C‐2) and 4 (C‐4) passages of 2.5 Mg water wagon axle load, applied to the entire plot every year during April/May for 20 consecutive years. Soil samples were obtained in November 2016 to determine the effects of various vehicular passages on C and nitrogen (N) contents and CO2 emissions. Soil CO2 fluxes were measured from November 16, 2016, to May 30, 2017, on the bi‐weekly (November to December and April to May) and monthly (January to March) basis by using high‐density polyvinyl chloride static gas chambers. The soil CO2 fluxes ranged from –1.05 to 9.03 g CO2 m−2 d−1. The lowest soil CO2 fluxes were observed in December coinciding with the minimum soil temperature. In general, daily soil CO2 fluxes were higher under C‐0 than those under other treatments. Vehicular traffic and axle load reduced the cumulative emission of CO2 by 22.6 and 29.8% under C‐2 and C‐4, respectively, compared with that under C‐0 (6.09 Mg ha−1). Soil and air temperatures had a significant positive correlation with the diurnal fluxes of soil CO2 in all the treatments except that under C‐4. Electrical conductivity, soil C and N contents and pools did not differ significantly among the treatments. Further, 2 to 4 passages of vehicles with 2.5 Mg of axle load decreased the soil CO2 emission on Crosby silt loam under NT as compared to that under the control. Therefore, continuous cultivation of row crops with moderate trafficking under NT and residue retention is recommended, and it also reduces the potential of soil CO2 emission while improving the soil organic C pools of well‐drained soils of Central Ohio.

Published: January 2019

AbstractQuantification with nondestructive techniques is not very well developed in the field of Cultural Heritage despite its interest. In the last decades, several works have been published using Raman spectroscopy for quantifying. However, depending on the methodology used, the information provided by this technique is not complete, and the results could lead to misunderstanding when dealing with unknown samples. In this work, a novel double quantification using Raman imaging (its representativeness would be higher than point‐by‐point analysis) and Laser Induce Breakdown Spectroscopy (LIBS) analyses is presented for analysis of Cultural Heritage samples. Several dolomitic marble samples, with some calcite impurities, covered or not by a calcium oxalate (whewellite, CaC2O4·H2O) layer were analysed in order to optimize the novel methodology. The agreement between the quantitative results from the independent analyses of the Raman Image data and the LIBS data is consistent within the uncertainty arising from both techniques. Further, the same methodology was applied on the same samples but using point‐by‐point Raman analysis with portable instruments, and portable LIBS information, showing again a great agreement between them and with the results obtained using the laboratory instruments.
Micellization of Carboxylic Acid Gemini Surfactant and Its Interaction with Amino Acid Surfactant in Aqueous Solution
Authors: Wang Ruijuan , Wang Dong , Yin Zhigang , Yang Xuzhao , Liu Quan 
Published: January 2019

AbstractThe carboxylic acid‐type Gemini surfactant (CGS12) was synthesized, and its micellization in aqueous solution at different pH values at 25.0 °C was investigated. The results show that the critical micelle concentration (CMC) of CGS12 at different pH values is only 10−6 order of magnitude, and the pH has little effect on the CMC. Moreover, the interaction of CGS12 with amino acid surfactant of sodium N‐lauroyl sarcosinate (SLS) at 25.0 °C and pH 7.0 was investigated using surface tension, dynamic light scattering (DLS), cryogenic transmission electron microscopy (Cryo‐TEM), and Ross–Miles foam measurements. The CGS12/SLS mixture shows a low CMC, and as a whole the CMC value becomes smaller with increasing molar fraction of CGS12 (XCGS12). Under different XCGS12, the mixtures form soluble aggregates with different hydration radii (Rh). Moreover, the mixture aggregates are mainly in the form of vesicles. The foaming height of CGS12 is worse than that of SLS, but the CGS12/SLS mixture has good foaming stability. This work reveals that the surfactant mixture has good surface activity and good foam stability.

Published: January 2019

AbstractIn this work, separation of multicomponent mixtures containing components with the same and different electrophoretic mobility by using orthogonal pressurised planar electrochromatography is studied theoretically. Additionally, a simple way for determination of a maximum amount of mixture causing volume overload of flat/planar columns used in this technique is presented. In the next stage, effects of change in different parameters on process performance by simulation case studies are investigated. A comparative study of separation productivity of orthogonal pressurised planar electrochromatography with the continuous and periodic modes of mixture delivery and column chromatography is carried out.

Published: January 2019

Objectives/HypothesisOptimal treatment for patients with vocal fold polyps (VFPs) remains controversial. We compared the short‐term outcomes of treatment with voice therapy alone (VT), surgery alone (SUR)m or voice therapy and surgery (VTS).Study DesignRetrospective case series.MethodsA retrospective study was performed for patients diagnosed with VFP (International Classification of Diseases, Ninth Revision code 478.4 and Tenth Revision code J38.1) between January 2010 and April 2016. Inclusion criteria were age greater than 18 years and charted evidence of treatment with voice therapy, surgery, or both. Exclusion criteria were history of laryngeal cancer or radiation above the clavicles. Outcomes measured included chart records of lesion absence, persistence or recurrence, and differences between pretreatment and post‐treatment Voice Handicap Index‐10 and GRBAS (G/grade, R/roughness, B/breathiness, A/asthenia, S/strain) scores.ResultsOne hundred twenty patients with VFPs were identified (SUR = 23, 19.2%, VT = 29, 24.2%, VTS = 68, 56.7%). Mean follow‐up was 5.5 months. There were no recurrences in 115 patients (95.8%). There was significant improvement from pre‐ to post‐treatment VHI‐10 scores in the SUR (mean improvement = 12.5, standard deviation [SD] = 12.7) and VTS (mean improvement = 12.3, SD = 10.3) groups compared to the VT (mean improvement = 2.84, SD = 11.9) group (P = .009). Pre‐ and post‐treatment GRBAS scores did not significantly change in any group.ConclusionsWhen using patient‐reported outcomes measures, patients with VFPs receive the greatest short‐term gains from treatment paradigms involving surgery or a combination of surgery and voice therapy. Voice therapy alone did not result in significant short‐term changes. Perceptual voice characteristics did not change significantly for any group. Further research on long‐term treatment outcomes for patients with VFPs is needed.Level of Evidence3 Laryngoscope, 129:1067–1070, 2019

AbstractOptical modulators hold great promise for nonlinear optical and photonic devices. However, current optical modulators are exclusively based on inorganic saturable absorbers such as semiconductor thin films, 2D materials, and plasmonic nanocrystals. Here, nonlinear optical modulation is demonstrated by designing a series of organic semiconducting polymer dots (Pdots) for passive Q‐switching and mode‐locking lasers in the near‐infrared (NIR) region. Combining density functional theory and judicious polymer design, Pdots with large extinction coefficient and broadband absorption are developed which span the entire spectrum from ultraviolet (UV) to NIR region (300 to 2500 nm). The Pdots exhibit strong saturable absorption (β = −1.2 × 10−3 cm W−1) and optical nonlinearity (Imχ(3) = −8.4 × 10−7 esu), which are of orders higher than other nonlinear optical materials such as carbon‐based materials, plasmonic metal nanoparticle, and semiconductor nanocrystals. The Pdot modulators are integrated into the fiber laser systems, and demonstrate passively mode‐locked lasers at 1036, 1038, 1945, 1950 nm and Q‐switched lasers at wavelengths of 1559 and 1957 nm, highlighting the potential of Pdots for advanced nonlinear optical and photonic applications.

AbstractThis article presents a 28 GHz switch and LNA chipset, and the RF front‐end module for 5G communication systems. The 28 GHz Single Pole Double Through (SPDT) switch and LNA MMICs are embedded in single RF front‐end module successfully using molding based embedded Wafer‐Level Package (eWLP) technology. For the low noise figure and high isolation, inductive source degenerated LNA topology and double shunt FET structure for SPDT switch are employed, and LNA and SPDT are implemented in single IC. The eWLP based package minimizes the parasitic component such as bond‐wire inductance and signals loss to enhance the performance of the RF front‐end module. At 28 GHz, the measured gain and noise figure of receiver path are 15.5 dB and 3.46 dB, respectively, and the IIP3 is +3 dBm at 45 mW power consumption.
Matching the principal deformation mode method with the probability transformation method for the analysis of uncertain systems
Authors: Falsone G. , Laudani R. 
Published: January 2019

SummaryThis paper deals with the probabilistic description of the random response of linear uncertain structural system when the uncertainties are modeled as random variables with assigned probability density function (pdf). In particular, a novel approach is presented that allows the direct evaluation of the response pdf starting from the joint pdf characterizing the structural uncertainties. It consists in matching adequately two methods, recently proposed by the authors, which are the Approximated Principal Deformation Modes method and the Probability Transformation Method. The proposed approach, obtained by this coupling, reveals to have good levels of accuracy, even for relatively high uncertainties, and of computational efficiency, as the reported numerical applications show.

Authors: Ngo Hung Viet , Edelenbos Jurian , Gianoli Alberto 
Published: January 2019

SummaryWith Public Administration Reform in Vietnam comes more local government responsibility for policy making. Building on the results of a multiple case study research on housing and infrastructure upgrading projects in four cities of Vietnam, it has been confirmed that the community participation and local government capacity in urban housing and infrastructure upgrading projects are positively related. The level of community participation in urban housing and infrastructure upgrading projects is influenced by local government capacity, and in turn, it has effects on the outcomes. There are some important aspects for the enhancement of the level of community participation. These are effective leadership, the financial resources aspect, and communication/information exchange. Moreover, based on the patterns of community participation in urban upgrading projects, it has been found that participation is strongly supported by government actors in these four cases, and a process of coproduction between the local government and the affected communities has taken place.
