Authors: López-Ortiz Citlali , Egan Tara , Gaebler-Spira Deborah J 
Published: September 2016

Introduction: This pilot study evaluates the effects of a targeted dance class utilizing classical ballet principles for rehabilitation of children with cerebral palsy on balance and upper extremity control. Methods: Twelve children with cerebral palsy (ages 7–15 years) with Gross Motor Function Classification scores II–IV participated in this study and were assigned to either a control group or targeted dance class group. Targeted dance class group participated in 1-h classes three times per week in a 4-week period. The Pediatric Balance Scale and the Quality of Upper Extremity Skills Test were administered before, after, and 1 month after the targeted dance class. Results: Improvements in the Pediatric Balance Scale were present in the targeted dance class group in before versus after and before versus 1 month follow-up comparisons (p-value = 0.0088 and p-value = 0.019, respectively). The Pediatric Balance Scale changes were not significant in the control group. The Quality of Upper Extremity Skills Test did not reach statistical differences in either group. Conclusion: Classical ballet as an art form involves physical training, musical accompaniment, social interactions, and emotional expression that could serve as adjunct to traditional physical therapy. This pilot study demonstrated improvements in balance control. A larger study with a more homogeneous sample is warranted.

Key Points
MOZ deletion in adult mice leads to a rapid loss of cells with HSC cell surface immuno-phenotype and transplantation ability. Absence of classically defined HSCs for an extended period does not substantially affect steady-state hematopoiesis.

Authors: Davis Jenny , Shute Jessica , Morgans Amee 
Published: September 2016

Background: The concept of a ‘good death’ involves end-of-life care in an appropriate setting and in keeping with the person's preferences. Limited research has examined the circumstances and place of death for older people living in residential aged care. Objective: This exploratory study investigated the nature of health service use and place of death of older people living in aged care to identify factors that lead to transfer of end-of-life care to other settings and poorer outcomes. Methods: Retrospective review of residential aged care client records between July 2014 and June 2015. Conclusion: The majority of people in this study died in their home setting of residential care and a number were in receipt of palliative care prior to their deaths. The study proposes a national approach to the use of terminology and documents related to palliative and end-of-life care and education in assessment and recognition of nearing the end of life.

Objectives: The UK National Institute for Health and Care Excellence (NICE) indicate that palliative care patients are at high risk of delirium and should be screened for it using the short confusion assessment method (short CAM). This study aimed to assess the perceptions of the short CAM for delirium screening amongst health-care workers in specialist palliative care inpatient units (SPCUs) and to investigate its use as a screening instrument. Methods: Patients in 5 SPCUs in the North East of England were screened for delirium using the short CAM and a staff survey assessed the acceptability of the short-CAM in this setting. Results: Of the 63 staff surveyed, 79.4% felt screening for delirium was important and 59.3% found the short CAM ‘not at all’ burdensome to complete. However, only 40.7% felt that the short-CAM often accurately reflected patients' conditions and none felt it always accurately reflected patients' condition. Of 298 patients screened, 20% screened positive on the short CAM. Malignant and intra-cerebral diseases were significant independent predictors of a positive screen. Hospice length of stay and in-hospice mortality were higher in those with a positive result (66.7%) than in those without (38.2%). Conclusions: Health professionals deem delirium screening to be important in SPCUs, but may not support routine use of the short CAM. This could reflect a limited perceived impact on care and lack of confidence in this tool to reflect a complex patient group.

Abstract
Nickerson, BS, Esco, MR, Bishop, PA, Schumacker, RE, Richardson, MT, Fedewa, MV, Wingo, JE, and Welborn, BA. Validity of selected bioimpedance equations for estimating body composition in men and women: a four-compartment model comparison. J Strength Cond Res 31(7): 1963–1972, 2017—The purpose of this study was to compare body fat percentage (BF%) and fat-free mass (FFM) values from bioelectrical impedance analysis (BIA) equations to values determined from a 4-compartment (4C) model. Eighty-two adults (42 men and 40 women) volunteered to participate (age = 23 ± 5 years). Body fat percentage and FFM were estimated from previously developed BIA equations by Chumlea et al. (BIACH), Deurenberg et al. (BIADE), Kyle et al. (BIAKYLE), and Sun et al. (BIASUN). Four-compartment model body composition was derived from underwater weighing for body density, dual-energy X-ray absorptiometry for bone mineral content, and bioimpedance spectroscopy for total body water. The standard error of estimate (SEE) for group BF% and FFM ranged from 3.0 to 3.8% and 2.1 to 2.7 kg, respectively. The constant error (CE) was significantly higher and lower for BF% and FFM (p < 0.001), respectively, for 3 BIA equations (BIACH, CE = 3.1% and −2.2 kg; BIADE, CE = 3.7% and −2.9 kg; BIAKYLE, CE = 2.3% and −1.9 kg), but was not significant for BF% (p = 0.702) and FFM (p = 0.677) for BIASUN (CE = −0.1% and 0.1 kg). The 95% limits of agreement were narrowest for BIACH (±5.9%; ±4.2 kg) and largest for BIADE (±7.4%; ±6.2 kg). The significant CE yielded by BIACH, BIADE, and BIAKYLE indicates these equations tend to overpredict group BF% and underestimate group FFM. However, all BIA equations produced low SEEs and fairly narrow limits of agreement. When the use of a 4C model is not available, practitioners might consider using one of the selected BIA equations, but should consider the associated CE.

Abstract
Diverse signals received by CD8+ T cells are integrated to achieve the required magnitude of cell expansion and the appropriate balance of effector/memory CD8+ T cell generation. Notably, the strength and nature of TCR signaling influence the differentiation and functional capacity of effector and memory CD8+ T cells. Dok-1 and Dok-2, the two members of the Dok family expressed in T cells, negatively regulate TCR signaling in vitro. However, the role of Dok proteins in modulating T cell function in vivo has not yet studied. We studied the function of Dok-1 and Dok-2 proteins in the regulation of the CD8+ T cell response to vaccinia virus infection. Comparison of responses to vaccinia virus expressing OVA peptide SIINFEKL by wild-type and Dok-1/2−/− CD8+ OT-I cells showed that the absence of Dok-1 and Dok-2 slightly reduced the magnitude of virus-specific effector CD8+ T cell expansion. This was not due to reduced proliferation or enhanced apoptosis of effector CD8+ T cells. Dok-1/2–deficient effector CD8+ T cells showed increased cell surface TCR expression following virus infection in vivo and increased expression of granzyme B and TNF upon stimulation with peptide Ag ex vivo. Finally, Dok-1/2–deficient effector CD8+ T had a severe defect in survival that resulted in impaired generation of memory CD8+ T cells. These results reveal the critical involvement of Dok-1 and Dok-2 in a negative-feedback loop that prevents overactivation of CD8+ T cells and promotes memory formation.
Pre‐eruptive inflation caused by gas accumulation: Insight from detailed gas flux variation at Sakurajima volcano, Japan

Published: September 2016

AbstractSulfur dioxide (SO2) emission rate observations were made at Sakurajima volcano, Japan, to quantify the relationship between the SO2 emission rate and inflation prior to Vulcanian explosions. The explosions associated with precursory inflation events were preceded by decreases in SO2 emission rates by 10–60 min. The amounts of accumulated gas were calculated using time series of SO2 emission rate. The amounts of accumulated SO2 and increases in strain records before the explosions showed a positive correlation. The volume increase of a deformation source calculated using the strain records was of the comparable order of magnitude as the volume of the accumulated volcanic gas. The results suggest that the inflations before the explosions were caused by the gas accumulation.
Estimation of cloud fraction profile in shallow convection using a scanning cloud radar

Published: September 2016

AbstractLarge spatial heterogeneities in shallow convection result in uncertainties in estimations of domain‐averaged cloud fraction profiles (CFP). This issue is addressed by using large eddy simulations of shallow convection over land coupled with a radar simulator. Results indicate that zenith profiling observations are inadequate to provide reliable CFP estimates. Use of scanning cloud radar (SCR), performing a sequence of cross‐wind horizon‐to‐horizon scans, is not straightforward due to the strong dependence of radar sensitivity to target distance. An objective method for estimating domain‐averaged CFP is proposed that uses observed statistics of SCR hydrometeor detection with height to estimate optimum sampling regions. This method shows good agreement with the model CFP. Results indicate that CFP estimates require more than 35 min of SCR scans to converge on the model domain average. The proposed technique is expected to improve our ability to compare model output with cloud radar observations in shallow cumulus cloud conditions.
Dipolarization front and current disruption
Authors: Lui A. T. Y. 
Published: September 2016

AbstractThe modification of current density on the dawn‐dusk cross section of the magnetotail with the earthward approach of a dipolarization front (DF) is examined through the recently published results of a three‐dimensional (3‐D) particle‐in‐cell (PIC) simulation. It is found that the current density intensifies by ~37% abruptly within ~1.5 ion gyrotime as the DF approaches and shows localized regions with north‐south extrusions. After reaching its peak value, it undergoes a drastic current reduction (DCR) by ~65% within ~2 ion gyrotime. Breakdown of the frozen‐in condition occurs in the neutral sheet region in association with DCR, demonstrating the non‐MHD behavior of the phenomenon. The evolution of current density from this 3‐D PIC simulation bears several similarities to those observed for the current disruption (CD) phenomenon, such as explosive growth and disruption of the current density leading to a breakdown of the frozen‐in condition. The evolution is also similar to those from a previous two‐dimensional (2‐D) PIC simulation specially designed to investigate the nonlinear evolution of the cross‐field current instability for CD. One interpretation of these findings is that CD and substorm triggering can be associated with earthward intrusion of a DF into the near‐Earth plasma sheet as indicated by previous Cluster and Time History of Events and Macroscale Interactions during Substorms observations. An alternative interpretation is that both DF and CD are consequences of a global evolution from an ion‐tearing‐like instability of the magnetotail.

AbstractWe present Jovian auroral observations from the 2014 January Hubble Space Telescope (HST) campaign and investigate the auroral signatures of radial transport in the magnetosphere alongside contemporaneous radio and Hisaki EUV data. HST FUV auroral observations on day 11 show, for the first time, a significantly superrotating polar spot poleward of the main emission on the dawnside. The spot transitions from the polar to main emission region in the presence of a locally broad, bright dawnside main emission feature and two large equatorward emission features. Such a configuration of the main emission region is also unreported to date. We interpret the signatures as part of a sequence of inward radial transport processes. Hot plasma inflows from tail reconnection are thought to flow planetward and could generate the superrotating spot. The main emission feature could be the result of flow shears from prior hot inflows. Equatorward emissions are observed. These are evidence of hot plasma injections in the inner magnetosphere. The images are thought to be part of a prolonged period of reconnection. Radio emissions measured by Wind suggest that hectometric (HOM) and non‐Io decametric (DAM) signatures are associated with the sequence of auroral signatures, which implies a global magnetospheric disturbance. The reconnection and injection interval can continue for several hours.
On the links between the radio flux and magnetodisk distortions at Jupiter

AbstractUsing measurements of the Galileo magnetometer and plasma wave instrument, it is shown that the flux of the Jovian auroral radio emissions is correlated with the azimuthal component of the magnetic field (Bφ) measured in the plasma disk, the situations of large magnetic twist of the disk (large ΔBφ, the difference between the measured and the model field) corresponding to enhanced radio intensities (frequency > 300 kHz). For the four orbits discussed here (three in the postmidnight and one in the premidnight sector), representing ~44 days of observations, from 25 to 85 Jovian radius in the magnetodisk, the radio intensity observed during periods of small radial current (ΔBφ < 1 nT) is typically a factor of 5 to 10 smaller than that observed at large radial current (ΔBφ > 5–6 nT). It is proposed that these variations are the direct consequences of enhanced magnetosphere/ionosphere coupling current systems linked to episodes of larger outward mass outflows in the disk, resulting in larger parallel currents and, thus, in enhanced auroral activity. The application of Hill's model shows that the observed variations of Bφ can be explained by increasing the mass outflow rate from ~150 kg/s (quiet periods) to more than 2 t/s (“energetic” events), for Pedersen conductance ranging from 0.1 to 1 S. This is consistent with the canonical values given in the literature. It is estimated that these modulations of the mass flow rates lead to variations of the power dissipated in the disk from ~1014 to 1015 W due to the torque exerted by the magnetic coupling with Jupiter's ionosphere, with a conversion rate into the power radiated by the radio waves of the order of 10−6.

AbstractOver 100 GPS sites measured in 2008–2013 in Peru provide new insights into the present‐day crustal deformation of the 2200 km long Peruvian margin. This margin is squeezed between the eastward subduction of the oceanic Nazca Plate at the South America trench axis and the westward continental subduction of the South American Plate beneath the Eastern Cordillera and Subandean orogenic wedge. Continental active faults and GPS data reveal the rigid motion of a Peruvian Forearc Sliver that extends from the oceanic trench axis to the Western‐Eastern Cordilleras boundary and moves southeastward at 4–5 mm/yr relative to a stable South America reference frame. GPS data indicate that the Subandean shortening increases southward by 2 to 4 mm/yr. In a Peruvian Sliver reference frame, the residual GPS data indicate that the interseismic coupling along the Nazca megathrust is highly heterogeneous. Coupling in northern Peru is shallow and coincides with the site of previous moderate‐sized and shallow tsunami‐earthquakes. Deep coupling occurs in central and southern Peru, where repeated large and great megathrust earthquakes have occurred. The strong correlation between highly coupled areas and large ruptures suggests that seismic asperities are persistent features of the megathrust. Creeping segments appear at the extremities of great ruptures and where oceanic fracture zones and ridges enter the subduction zone, suggesting that these subducting structures play a major role in the seismic segmentation of the Peruvian margin. In central Peru, we estimate a recurrence time of 305 ± 40 years to reproduce the great 1746Mw~8.8 Lima‐Callao earthquake.
Nonlinear inversion of tilt‐affected very long period records of explosive eruptions at Fuego volcano
Authors: Waite Gregory P. , Lanza Federica 
Published: September 2016

AbstractMagmatic processes produce a rich variety of volcano seismic signals, ranging over several orders of magnitude in frequency and over a wide range of mechanism types. We examined signals from 400 to 10 s period associated with explosive eruptions at Fuego volcano, Guatemala, that were recorded over 19 days in 2009 on broadband stations with 30 s and 60 s corner periods. The raw data from the closest stations include tilt effects on the horizontal components but also have significant signal at periods below the instrument corners on the vertical components, where tilt effects should be negligible. We address the problems of tilt‐affected horizontal waveforms through a joint waveform inversion of translation and rotation, which allows for an investigation of the varying influence of tilt with period. Using a phase‐weighted stack of six similar events, we invert for source moment tensor using multiple bands. We use a grid search for source type and constrained inversions, which provides a quantitative measure of source mechanism reliability. The 30‐10 s band‐pass results are consistent with previous work that modeled data with a combined two crack or crack and pipe model. At the longest‐period band examined, 400‐60 s, the source mechanism is like a pipe that could represent the shallowest portion of the conduit. On the other hand, source mechanisms in some bands are unconstrained, presumably due to the combined tilt‐dominated and translation‐dominated signals, which are not coincident in space and have different time spans.
Recent warming on Spitsbergen—Influence of atmospheric circulation and sea ice cover

Published: September 2016

AbstractSpitsbergen has experienced some of the most severe temperature changes in the Arctic during the last three decades. This study relates the recent warming to variations in large‐scale atmospheric circulation (AC), air mass characteristics, and sea ice concentration (SIC), both regionally around Spitsbergen and locally in three fjords. We find substantial warming for all AC patterns for all seasons, with greatest temperature increase in winter. A major part of the warming can be attributed to changes in air mass characteristics associated with situations of both cyclonic and anticyclonic air advection from north and east and situations with a nonadvectional anticyclonic ridge. In total, six specific AC types (out of 21), which occur on average 41% of days in a year, contribute approximately 80% of the recent warming. The relationship between the land‐based surface air temperature (SAT) and local and regional SIC was highly significant, particularly for the most contributing AC types. The high correlation between SAT and SIC for air masses from east and north of Spitsbergen suggests that a major part of the atmospheric warming observed in Spitsbergen is driven by heat exchange from the larger open water area in the Barents Sea and region north of Spitsbergen. Finally, our results show that changes in frequencies of AC play a minor role to the total recent surface warming. Thus, the strong warming in Spitsbergen in the latest decades is not driven by increased frequencies of “warm” AC types but rather from sea ice decline, higher sea surface temperatures, and a general background warming.
