Non-pharmacological Intervention for Chronic Pain in Veterans: A Pilot Study of Heart Rate Variability Biofeedback
Authors: Berry Melanie E. , Chapple Iva T. , Ginsberg Jay P. , Gleichauf Kurt J. , Meyer Jeff A. , Nagpal Madan L.
Published: April 2014

Objective:

Chronic pain is an emotionally and physically debilitating form of pain that activates the body's stress response and over time can result in lowered heart rate variability (HRV) power, which is associated with reduced resiliency and lower self-regulatory capacity. This pilot project was intended to determine the effective-ness of HRV coherence biofeedback (HRVCB) as a pain and stress management intervention for veterans with chronic pain and to estimate the effect sizes. It was hypothesized that HRVCB will increase parasympathetic activity resulting in higher HRV coherence measured as power and decrease self-reported pain symptoms in chronic pain patients.

Study design:

Fourteen veterans receiving treatment for chronic pain were enrolled in the pre-post intervention study. They were randomly assigned, with 8 subjects enrolled in the treatment group and 6 in the control group. The treatment group received biofeedback intervention plus standard care, and the other group received standard care only. The treatment group received four HRVCB training sessions as the intervention.

Measures:

Pre-post measurements of HRV amplitude, HRV power spectrum variables, cardiac coherence, and self-ratings of perceived pain, stress, negative emotions, and physical activity limitation were made for both treatment and control groups.

Results:

The mean pain severity for all subjects at baseline, using the self-scored Brief Pain Inventory (BPI), was 26.71 (SD=4.46; range=21—35) indicating a moderate to severe perceived pain level across the study subjects. There was no significant difference between the treatment and control groups at baseline on any of the measures. Post-HRVCB, the treatment group was significantly higher on coherence (P=.01) and lower (P=.02) on pain ratings than the control group. The treatment group showed marked and statistically significant (1-tailed) increases over the baseline in coherence ratio (191%, P=.04) and marked, significant (1-tailed) reduction in pain ratings (36%, P<.001), stress perception (16%, P=.02), negative emotions (49%, P<.001), and physical activity limitation (42%, P<.001). Significant between-group effects on all measures were found when pre-training values were used as covariates.

Conclusions:

HRVCB intervention was effective in increasing HRV coherence measured as power in the upper range of the LF band and reduced perceived pain, stress, negative emotions, and physical activity limitation in veterans suffering from chronic pain. HRVCB shows promise as an effective non-pharmacological intervention to support standard treatments for chronic pain.
Intuitive Intelligence, Self-regulation, and Lifting Consciousness
Authors: Mccraty Rollin , Zayas Maria
Published: April 2014

This article explores the role of the heart in emotional experience, as well as how learning to shift the rhythms of the heart into a more coherent state makes it possible to establish a new inner baseline reference that allows access to our heart's intuitive capacities and deeper wisdom. The nature and types of intuition and the connection between intuition and compassionate action are discussed. It is suggested that increased effectiveness in self-regulatory capacity and the resultant reorganization of memories sustained in the neural architecture facilitates a stable and integrated experience of self in relationship to others and to the environment, otherwise known as consciousness. The implications of meeting the increasingly complex demands of life with greater love, compassion, and kindness, thereby lifting consciousness, are considered.

Authors: Weltman Gershon , Lamon Jonathan , Freedy Elan , Chartrand Donald
Published: April 2014

The objective of this case study was to test the impact in law enforcement personnel of an innovative self-regulation and resilience building program delivered via an iPad (Apple Inc, Cupertino, California) app and personal mentoring. The Stress Resilience Training System (SRTS) app includes training on stress and its effects, HRV coherence biofeedback, a series of HeartMath self-regulation techniques (The Institute of HeartMath, Boulder Creek, California), and HRV-controlled games. The stressful nature of law enforcement work is well established, and the need for meaningful and effective stress resilience training programs is becoming better understood, as it has been in the military. Law enforcement and military service share many stress-related features including psychological stressors connected with the mission, extended duty cycles, and exposure to horrific scenes of death and injury. San Diego (California) Police Department personnel who participated in the study were 12 sworn officers and 2 dispatchers, 10 men and 4 women. The SRTS intervention comprised an introductory 2-hour training session, 6 weeks of individualized learning and practice with the SRTS app, and four 1-hour telephone mentoring sessions by experienced HeartMath mentors spread over a four week period. Outcome measures were the Personal and Organizational Quality Assessment (POQA) survey, the mentors’ reports of their observations, and records of participants’ comments from the mentoring sessions. The POQA results were overwhelmingly positive: All four main scales showed improvement; Emotional Vitality improved by 25% (P=.05) and Physical Stress improved by 24% (P=.01). Eight of the nine subscales showed improvement, with the Stress subscale, perhaps the key measure of the study, improving by approximately 40% (P=.06). Participant responses were also uniformly positive and enthusiastic. Individual participants praised the program and related improvements in both on-the-job performance and personal and familial situations. The results support the efficacy of the program to achieve its goal of building stress resilience and improving officer wellness by providing practical self-regulation skills for better management of emotional energy. We conclude that the SRTS program for building resilience and improving psychological wellness can be as effective for law enforcement as it is for military personnel.

Published: April 2014

We have found undiscovered defects on a 4H-SiC epitaxial layer, the shape of which resembles a scraper in images taken by confocal differential interference contrast optical microscopy. The surface morphological structure and formation mechanism of the scraper-shaped defects were investigated by atomic force microscopy and grazing incidence monochromatic synchrotron X-ray topography, respectively. The scraper-shaped defects were surface morphological defects consisting of surface asperity and were caused by the migration of interfacial dislocations. The evaluation of the thermal oxide reliability of metal–oxide–semiconductor capacitors fabricated on these defects was performed by time-dependent dielectric breakdown measurement. The degradation of thermal oxide occurred only on the downstream line of the scraper-shaped defects. The thickness of the oxide layer on these defects was also investigated using cross-sectional transmission electron microscopy.

Triboelectrification
Authors: Schein Lawrence B. , Castle G. S. Peter , Lacks Daniel J.
Published: April 2014

Triboelectrification, more accurately known as contact charging, is used to describe the exchange of electrostatic charge between two surfaces when they are brought into contact. This article reviews the various charging methods that are used to charge materials and discusses some practical applications of such charging. In addition cases where the charges may lead to nuisances and hazards are described. The various methods whereby the charge may be measured are summarized and the limitations discussed. The main part of the paper deals with mechanisms of contact charging and the state of our current understanding of the theory behind the process and the factors that affect the magnitude of the charge transfer.
Substorm occurrence during quiet solar wind driving
Authors: Pulkkinen T. I. , Partamies N. , Kilpua E. K. J.
Published: April 2014

We examine the OMNI database and International Monitor for Auroral Geomagnetic Effects (IMAGE) magnetometer chain records to study the substorm occurrence and characteristics during quiet solar driving periods, especially during the solar minimum period in 2009. We define substorm‐like activations as periods where the hourly average AL is below −200 nT. Using the OMNI data set, we demonstrate that there are limiting solar wind speed, interplanetary magnetic field magnitude, and driving electric field values below which substorm‐like activations (AL < 200 nT, intensification and decay of the electrojet) do not occur. These minimum parameter values are V < 266 km/s, B < 1.4 nT, and E < 0.025 mV/m; such low values are observed less than 1% of the time. We also show that for the same level of driving solar wind electric field, the electrojet intensity is smaller (by few tens of nT), and the electrojet resides farther poleward (by over 1°) during extended quiet solar driving in 2009 than during average solar activity conditions. During the solar minimum period in 2009, we demonstrate that substorm‐like activations can be identified from the IMAGE magnetometer chain observations during periods when the hourly average IL index is below −100 nT. When the hourly IL activity is smaller than that, which covers 87% of the nighttime observations, the electrojet does not show coherent behavior. We thus conclude that substorm recurrence time during very quiet solar wind driving conditions is about 5–8 h, which is almost double that of the average solar activity conditions.

Nanostructured materials and their interfaces have attracted recent interest for their functionality in a wide variety of different applications. However, the origins of these properties in several instances remain unknown. One promising aspect of nanomaterials is their role in materials design for mitigating radiation damage. In particular, engineered radiation tolerant materials would exploit the presence of internal interfaces to act as recombination centers and suppress damage accumulation. Realizing this promise, however, requires a fundamental understanding of how radiation‐induced defects interact with interfaces. Thus, studying the interfacial atomic structure and chemistry before and after irradiation is critical. In this study, we have performed transmission electron microscopy on a series of pristine and ion‐irradiated oxide interfaces to probe radiation‐induced effects. The CeO2/SrTiO3 interface, chosen as a model system for these studies, is characterized by differences in SrTiO3 terminations or steps. Our salient result is that steps are centers for preferential amorphization in SrTiO3, which we attribute to defect flow across the interface induced by non‐stoichiometry in CeO2. The study concludes the interfacial atomic ordering in the form of steps thereby modifies the response to ion irradiation and suggests interface patterning as another parameter to functionalize radiation tolerant materials.
Differentiating maturational influence on training‐induced strength and endurance adaptations in prepubescent children
Authors: Marta Carlos C. , Marinho Daniel A. , Izquierdo Mikel , Marques Mário C.
Published: April 2014

Objective

To analyze the effect of biological maturation on training‐induced strength and endurance adaptations in the prepubertal growth spurt.

Methods

One hundred and twenty‐five healthy children (58 boys, 67 girls), aged 10–11 years old (10.8 ± 0.4 years), who were self‐assessed as belonging to Tanner stages I and II, were randomly divided into two experimental groups, a strength training group (19 boys, 22 girls) and an endurance training group (21 boys, 24 girls) that would train twice a week for 8 weeks, as well as a control group (18 boys, 21 girls; no training program).

Results

After 8 weeks of training, there were improvements in all strength and endurance measures (P < 0.01) for both groups of Tanner stage I and II children. No significant differences in training response were observed relative to biological maturity or gender (P > 0.05).

Conclusions

These data suggest that more biologically mature prepubescent children seem to have no advantage in training‐induced strength and endurance adaptations compared with their less mature peers. Additionally, gender did not affect the training‐induced changes in strength or aerobic fitness. These results are meaningful for the development of optimized well‐rounded training programs in prepubertal children. Am. J. Hum. Biol. 26:469–475, 2014. © 2014 Wiley Periodicals, Inc.

Authors: Tzeng Michael , du Souich Christèle , Cheung Helen Wing‐Hong , Boerkoel Cornelius F.
Published: April 2014

Coffin‐Siris Syndrome (CSS) is an intellectual disability disorder caused by mutation of components of the SWI/SNF chromatin‐remodeling complex. We describe the evolution of the phenotypic features for a male patient with CSS from birth to age 7 years and 9 months and by review of reported CSS patients, we expand the phenotype to include neonatal and infantile hypertonia and upper airway obstruction. The propositus had a novel de novo heterozygous missense mutation in exon 17 of SMARCA4 (NM_001128849.1:c.2434C>T (NP_001122321.1:p.Leu812Phe)). This is the first reported mutation within motif Ia of the SMARCA4 SNF2 domain. In summary, SMARCA4‐associated CSS is a pleiotropic disorder in which the pathognomic clinical features evolve and for which the few reported individuals do not demonstrate a clear genotype–phenotype correlation. © 2014 Wiley Periodicals, Inc.
Rhodium(II)‐Catalyzed Intramolecular Annulation of 1‐Sulfonyl‐1,2,3‐Triazoles with Pyrrole and Indole Rings: Facile Synthesis of N‐Bridgehead Azepine Skeletons
Authors: Yang Jin‐Ming , Zhu Cheng‐Zhi , Tang Xiang‐Ying , Shi Min
Published: April 2014

A convenient and efficient synthetic method has been developed to construct highly functionalized N‐bridgehead azepine skeletons, which are of great importance in biological and pharmaceutical industry. The reaction proceeds through a rhodium(II) azavinyl carbene intermediate, which initiated the intramolecular CH functionalization with pyrrolyl and indolyl rings. A variety of azepine derivatives were obtained in moderate to good yields under mild reaction conditions with high chemoselectivity. Several interesting derivatizations of the resulting products demonstrate that this method is synthetically valuable and useful.
[B30]−: A Quasiplanar Chiral Boron Cluster

Published: April 2014

Chirality is vital in chemistry. Its importance in atomic clusters has been recognized since the discovery of the first chiral fullerene, the D2 symmetric C76.1 A number of gold clusters have been found to be chiral,2 raising the possibility to use them as asymmetric catalysts. The discovery of clusters with enantiomeric structures is essential to design new chiral materials with tailored chemical and physical properties.3 Herein we report the first inherently chiral boron cluster of [B30]− in a joint photoelectron spectroscopy and theoretical study. The most stable structure of [B30]− is found to be quasiplanar with a hexagonal hole. Interestingly, a pair of enantiomers arising from different positions of the hexagonal hole are found to be degenerate in our global minimum searches and both should co‐exist experimentally because they have identical electronic structures and give rise to identical simulated photoelectron spectra.
Development of a melt‐extrudable biobased soy flour/polyethylene blend for multilayer film applications
Authors: Thellen Christopher , Hauver Corey , Ratto Jo Ann
Published: April 2014

Monolayer and multilayer films from biobased linear low‐density polyethylene and milled soy flour were produced through cast film coextrusion processes using conventional thermoplastic processing equipment. Films containing 10 and 20% by weight of soy flour milled to maximum particle sizes of 8, 11, and 22 µm were extruded and characterized as a packaging film material. Water resistance, tensile properties, and gas permeability were measured on each film and analyzed with respects to the soy particle size, soy loading, and layer configuration in the multilayer film structure. Mechanical properties results indicated that ultimate elongation of the soy‐containing films decreased by as much as 14% compared to the control, while tensile strength and maximum load testing did not reveal any identifiable trends. Monolayer soy‐containing film showed high moisture sensitivity, as measured by contact angle and absorption testing, while the multilayer films demonstrated a more hydrophobic nature as indicated by higher contact angle measurements. This increase in hydrophobic properties is due to protective polyolefin skin layers, which are more hydrophobic. Oxygen transmission rates of the multilayer films decreased by 38% due to the presence of soy flour as compared to the control that did not contain any soy flour. © 2014 Wiley Periodicals, Inc. J.

Environmental Innovations and Internationalization: Theory and Practices
Authors: Chiarvesio Maria , Marchi Valentina De , Maria Eleonora Di
Published: April 2014

Based on original data on Italian firms specializing in medium‐ and low‐tech industries, we study the relationship between firms’ upstream and downstream internationalization and their propensity to introduce products or processes that reduce environmental impact. Preliminary evidence suggests that geography plays an important role in green firms’ activities and supply chains. More precisely, results suggest that firms that outsource to and rely on non‐local suppliers are less likely to engage in environmental innovations. Moreover, we verify that firms engaged in export activities play a similar and negative role, regardless of the export intensity and typology of foreign markets (i.e. developed versus emerging). Tapping global flows of knowledge by being a part of a multinational group positively spurs the development of green innovations, as for FDIs.

Quaternary Sulfide Ba6Zn6ZrS14: Synthesis, Crystal Structure, Band Structure, and Multiband Physical Properties
Authors: Zhang Xian , He Jianqiao , Chen Wei , Zhang Ketian , Zheng Chong , Sun Junliang , Liao Fuhui , Lin Jianhua , Huang Fuqiang
Published: April 2014

Ba6Zn6ZrS14 was synthesized by a traditional salt‐melt method with KI as flux. The pale yellow crystals of Ba6Zn6ZrS14 crystallize in the tetragonal space group I4/mcm with a=16.3481 (4) Å and c=9.7221(6) Å. The structure features unique one‐dimensional parallel [Zn6S9]6− and [ZrS5]6− straight chains. The D2h‐symmetric [Zn6S9]6− cluster serves as the building block of the [Zn6S9]6− chains. A powder sample was investigated by X‐ray diffraction, optical absorption, and photoluminescence measurements. The compound shows multiple‐absorption character with three optical absorption edges around 1.78, 2.50, and 2.65 eV, respectively, which are perfectly consistent with the results of first‐principles calculations. Analysis of the density of states further revealed that the three optical absorption bands are attributable to the three S(3p6)→Zr(4d0) transitions due to the splitting of the Zr 4d orbitals in the D4h crystal field. The multiband nature of Ba6Zn6ZrS14 also results in photocatalytic activity under visible‐light irradiation and three band‐edge emissions.
Enhanced Formaldehyde‐Vapor Adsorption Capacity of Polymeric Amine‐Incorporated Aminosilicas
Authors: Nomura Akihiro , Jones Christopher W.
Published: April 2014

Airborne formaldehyde, which is a highly problematic volatile organic compound (VOC) pollutant, is adsorbed by polymeric amine‐incorporated silicas (aminosilicas), and the factors that affect the adsorption performance are systematically investigated. Three different types of polymeric amines 1) poly(ethyleneimine) branched (PEIBR); 2) poly(ethyleneimine) linear (PEILI); and 3) poly(allylamine) (PAA) are impregnated into two types of porous silicas [SBA‐15 and mesocellular foam (MCF) silicas] with systematic changes of the amine loadings. The adsorption results demonstrate that the adsorption capacity increases along with the amine loading until the polymeric amines completely fill the silica pores. This results in the MCF silica, which has a larger pore volume and hence can accommodate more polymeric amine before completely filling the pore, giving materials that adsorb more formaldehyde, with the largest adsorption capacity, q, of up to 5.7 mmolHCHO g−1 among the samples studied herein. Of the three different types of polymers, PAA, comprised of 100 % primary amines, showed the highest amine efficiency μ (mmolHCHO/mmolN) for capturing formaldehyde. The chemical structures of the adsorbed formaldehyde are analyzed by 13C cross‐polarization magic‐angle spinning (CP‐MAS) NMR, and it is demonstrated that the adsorbed formaldehyde is chemically attached to the aminosilica surface, forming hemiaminal and imine species. Because the chemical adsorption of formaldehyde forms covalent bonds, it is not desorbed from the aminosilicas below 130 °C based on temperature‐programed‐desorption (TPD) analysis. The high formaldehyde‐adsorption capacity and stability of the trapped formaldehyde on the amine surface in this study reveal the potential utility of aminosilicas as formaldehyde abatement materials.
Dual Protection of Sulfur by Carbon Nanospheres and Graphene Sheets for Lithium–Sulfur Batteries
Authors: Wang Bei , Wen Yanfen , Ye Delai , Yu Hua , Sun Bing , Wang Guoxiu , Hulicova‐Jurcakova Denisa , Wang Lianzhou
Published: April 2014

Well‐confined elemental sulfur was implanted into a stacked block of carbon nanospheres and graphene sheets through a simple solution process to create a new type of composite cathode material for lithium–sulfur batteries. Transmission electron microscopy and elemental mapping analysis confirm that the as‐prepared composite material consists of graphene‐wrapped carbon nanospheres with sulfur uniformly distributed in between, where the carbon nanospheres act as the sulfur carriers. With this structural design, the graphene contributes to direct coverage of sulfur to inhibit the mobility of polysulfides, whereas the carbon nanospheres undertake the role of carrying the sulfur into the carbon network. This composite achieves a high loading of sulfur (64.2 wt %) and gives a stable electrochemical performance with a maximum discharge capacity of 1394 mAh g−1 at a current rate of 0.1 C as well as excellent rate capability at 1 C and 2 C. The improved electrochemical properties of this composite material are attributed to the dual functions of the carbon components, which effectively restrain the sulfur inside the carbon nano‐network for use in lithium–sulfur rechargeable batteries.
