Authors: Kinsey Eliza Whiteman , Dupuis Roxanne , Oberle Megan , Cannuscio Carolyn C , Hillier Amy 
Published: May 2019

AbstractObjective:The present study explored chronic disease management over the monthly benefit cycle among primary food shoppers from households receiving Supplemental Nutrition Assistance Program (SNAP) benefits in Philadelphia, PA, USA.Design:In-depth interviews, participant observation and surveys were conducted with the primary food shopper of SNAP households.Setting:Interviews and surveys were conducted in a clinical setting at Children’s Hospital of Philadelphia, at participants’ homes, and in food procurement settings including grocery stores, food pantries and soup kitchens.Participants:Eighteen adults who received SNAP; five with a diet-related chronic condition, five managing the chronic condition of a family member and thirteen with overweight or obesity.Results:All households had at least one member with a chronic disease or condition. Households reported that the dietary demands of managing chronic illnesses were expensive and mentally taxing. Food and financial shortfalls at the end of the benefit cycle, as well as reliance on charitable food assistance programmes, often had negative impacts on chronic disease self-management.Conclusions:Drawing from nearly 50 h of in-depth qualitative interviews with SNAP participants, the study highlights the dual cognitive burden of poverty and chronic disease and elucidates the particular challenges of food procurement and maintenance of diet quality throughout the benefit month faced by SNAP households with diet-related chronic diseases. Interventions targeted at reducing the cost of medically appropriate, healthy foods may help to improve chronic disease self-management within SNAP populations.
The Parity and Disparity between Inner and Outer Experience in Kant
Authors: Kraus Katharina 
Published: May 2019

AbstractThis article advocates a new interpretation ofinner experience– the experience that one has of one’s empirical-psychological features ‘from within’ – in Kant. It argues that for Kant inner experience is the empirical cognition of mental states, but not that of a persistent mental substance. The schema of persistence is thereby substituted with the regulative idea of the soul. This view is shown to be superior to two opposed interpretations: the parity view that regards inner experience as empirical cognition of a mental object on a par with outer experience and the disparity view that denies altogether that inner experience is empirical cognition.
Autonomy and the Idea of Freedom: Some Reflections onGroundworkIII
Authors: Reath Andrews 
Published: May 2019

AbstractThis article explores a set of questions about the ‘idea of freedom’ that Kant introduces in the fourth paragraph ofGroundworkIII. I develop a reading that supports treating it as a normative notion and brings out its normative content in some detail. I argue that we should understand the idea as follows: that it is a general feature of reasoning and judgement that it understands itself to be a correct or sound application of the normative standards of the relevant domain of cognition, not influenced by irrelevant or external factors. Reasoning and judgement are thus normatively committed to these standards of correctness. A second and related concern is to explore connections between the idea of freedom and Kant’s conception of autonomy and to identify different points at which autonomy plays a role in the argument ofGroundworkIII. In the final section, I mine the idea of freedom for a set of normative commitments specific to rational agency that play a foundational role in Kant’s moral conception.
Human Rights in a Kantian Key
Authors: Sangiovanni Andrea 
Published: May 2019

AbstractThis article discusses Luigi Caranti’s Kant’s Political Legacy, which argues, among other things, that a Kantian reconstruction of dignity can provide a foundation for human rights. Caranti’s book is one of the most powerful recent reconstructions of Kant’s political philosophy. Four main points are argued in response. First, to what extent can dignity understood as a value ground the essentially relational character of human rights claims? Second, does Caranti explain why our mere rational capacity to set moral ends has dignity rather than the realization of that capacity in a morally righteous will? Third, how can the argument provided avoid the conclusion that, because people’s capacities vary, their dignity varies too? Fourth, is Kant’s political philosophy incompatible with our modern understanding of human rights and, in particular, their function in international law and practice?

AbstractObjectiveThiamine deficiency (TD) is recognized in various kinds of disease with associated loss of appetite including cancer. However, it has not been recognized to date in bereaved partners after spousal loss from cancer.MethodFrom a series of bereaved partners who lost a spouse to cancer, we report on those who developed TD after bereavement.ResultCase 1 was a 57-year-old woman who sought consultation at our “bereavement clinic.” Her husband had been diagnosed with pancreatic cancer one year earlier and had died one month previously. At the first visit, she was observed to suffer depression, anxiety, and decreased appetite. Neurological, blood, and biochemical examinations did not reveal any noteworthy findings. She was diagnosed with uncomplicated bereavement. Detailed examination revealed that her appetite had been markedly decreased for approximately five weeks. The diagnosis of TD was supported by her abnormally low serum thiamine level. Case 2 was a bereaved 73-year-old male who had lost his wife to hypopharyngeal cancer one month previously after a five-year illness. He had shown a lack of energy for the month preceding his wife's death, but because there was no improvement after her death, his family recommended he seek consultation at our “bereavement clinic.” He was suffering from major depressive disorder. Detailed examination revealed that his appetite had been decreased for more than two weeks. Again, the diagnosis of TD was supported by his abnormally low serum thiamine level.Significance of resultsThese reports demonstrate that there is a possibility that bereaved could develop TD after the loss of a loved one. TD should be considered whenever there is a loss of appetite lasting for more than 2 weeks, and medical staff should pay careful attention to the physical condition of the bereaved to prevent complications because of TD.

AbstractMaternal pre-pregnancy weight has been related with young singletons’ cognitive and behavioral development, but it is not clear if it has an effect on temperament. We used a twin cohort to evaluate the association between maternal pre-pregnancy body mass index (BMI) and infants’ temperament. The mothers of 834 twins answered questions regarding their pre-pregnancy BMI and their 0- to 18-month-old children’s temperament using the Revised Infant Behavior Questionnaire. Three temperamental dimensions were examined: activity level, distress to limitation and duration of orienting. The relationship between maternal pre-pregnancy BMI and each temperamental component was investigated by means of multilevel mixed-effects linear regression analysis. We found no clear evidence of an association of maternal pre-pregnancy BMI with twins’ temperament. The development of temperament is influenced by a large number of factors, probably different from those influencing children’s emotional and behavioral development.
Temporal Variations in Water Chemistry of the (Lower) Brahmaputra River: Implications to Seasonality in Mineral Weathering

Published: May 2019

AbstractDissolved major ions and Sr concentrations of the Brahmaputra River at Guwahati, India, have been investigated on weekly basis for one year to understand the seasonality in weathering pattern and relative contributions from possible solute sources. Comparison of major ion data sets from present and earlier studies for this location shows no appreciable change during last ~50 years. Elemental concentrations and Ca/Na* (Na* = Na − Cl) ratio of the Brahmaputra covary (inversely) with the water discharge; the degree of seasonality, however, is less pronounced compared to other Himalayan (e.g., Ganga and Salween) rivers. The monthly averaged Ca/Si ratios of the Brahmaputra (3.7 ± 0.2), which is lower by ~2 times than those reported earlier for the Ganga outflow (6 ± 1), show minimal (~6%) seasonal changes. Seasonal variability in Na*/K with higher ratios during non‐monsoon period has been attributed to proportionally higher Na supply from hot springs and/or alkaline salts. The silicate‐derived cations (Cats) and Sr (Srs) have been estimated using an inversion method. Although these estimated values broadly show seasonal changes, the average Cats and Srs values for the monsoon (26 ± 4% [Cats]; 26 ± 6% [Srs]) and non‐monsoon (27 ± 3% (Cats); 24 ± 4% (Srs)) seasons are statistically same. These estimates indicate a weak runoff‐weathering linkage for the Brahmaputra river. Outcomes from this study suggest that the chemical weathering intensity of this basin is more dominated by regional rapid weathering around the eastern syntaxis than the climatic (runoff) parameters.

AbstractA frequency‐tunable resonance scattering lidar with high temporal/vertical resolutions (1 min/15 m) observed sporadic calcium ion (Ca+s) layers at ~100 km over Tachikawa (geographical/geomagnetic latitude: 35.7°N/27.1°N), Japan, on 21–22 August 2014. Simultaneously, sporadic E (Es) parameters and medium‐scale traveling ionospheric disturbances (MSTIDs) were observed by an ionosonde and Global Navigation Satellite System receiver network, GEONET, respectively. The maximum densities of the Ca+ and electrons in the Es layer had a strong positive correlation. As observation started ~23:30 LT, the Ca+s layer and the associated Es layer descended at ~2.8 km/hr with density irregularities including Kelvin‐Helmholtz billow‐like structures suggesting the presence of background neutral wind shear and instability. And the total electron content variations showed large amplitude associated with the MSTIDs at an altitude of 300 km in synchronization with the Ca+ column abundance surges at 100 km over Tachikawa; in their respective E and F region locations connected by geomagnetic field line these irregularities are found to vary in phase. At ~02:00 LT, the Ca+s layer stopped descending at ~100 km due to larger ion‐neutral collision frequency in the lower altitudes and resided there quietly until sunrise; both Ca+ column abundance enhancements and the large total electron content variation disappeared as the descent of the Ca+s layer stopped, implicating that the MSTID structure cannot be sustained without the density irregularities of the Es layer. This is the first synchronous observation of the coupling between the Es density irregularities and the MSTIDs in the F region along a common magnetic flux tube.
A Bootstrap‐Based Approach for Improving Measurements by Retarding Potential Analyzers
Authors: Debchoudhury Shantanab , Sengupta Srijan , Earle Gregory , Coley William 
Published: May 2019

AbstractRetarding potential analyzers are frequently flown on small satellites as in situ ion probes, from which can be derived a number of ion plasma parameters from a current‐voltage relationship (I‐V curve). The traditional method of analyzing retarding potential analyzer data produces inaccuracies in derived estimates when there is significant noise present in the instrument measurements. In this study we investigate the dependencies between parameters that produce uncertainties in noisy I‐V curves. It is found that multiple combinations of ion velocity and spacecraft floating potential can produce I‐V curves that lie within the noise envelope, which renders it difficult for a traditional curve fitting technique to objectively and accurately estimate parameters from a noisy I‐V curve. In this paper we propose BATFORD—a bootstrap resampling‐based technique to improve the accuracies of parameter estimates. It is particularly useful when signal‐to‐noise ratios are low. The algorithm is tested against a traditional curve fitting method for a simulated data set comprising I‐V curves for the middle‐ and low‐latitude ionosphere at low Earth orbit altitudes around 450 km, where O+ is the predominant species. BATFORD is found to provide more robust and reliable estimates assuming generalized noise distribution characteristics. As further validation, the algorithm is applied to satellite data from an orbit with deep plasma bubbles and hence low signal levels.
Are the Moon's Nearside‐Farside Asymmetries the Result of a Giant Impact?

Published: May 2019

AbstractThe Moon exhibits striking geological asymmetries in elevation, crustal thickness, and composition between its nearside and farside. Although several scenarios have been proposed to explain these asymmetries, their origin remains debated. Recent remote sensing observations suggest that (1) the crust on the farside highlands consists of two layers: a primary anorthositic layer with thickness of ~30‐50 km and on top a more mafic‐rich layer ~10 km thick and (2) the nearside exhibits a large area of low‐Ca pyroxene that has been interpreted to have an impact origin. These observations support the idea that the lunar nearside‐farside asymmetries may be the result of a giant impact. Here using quantitative numerical modeling, we test the hypothesis that a giant impact on the early Moon can explain the striking differences in elevation, crustal thickness, and composition between the nearside and farside of the Moon. We find that a large impactor, impacting the current nearside with a low velocity, can form a mega‐basin and reproduce the characteristics of the crustal asymmetry and structures comparable to those observed on the current Moon, including the nearside lowlands and the farside's mafic‐rich layer on top of a primordial anorthositic crust. Our model shows that the excavated deep‐seated KREEP (potassium, rare earth elements, and phosphorus) material, deposited close to the basin rim, slumps back into the basin and covers the entire basin floor; subsequent large impacts can transport the shallow KREEP material to the surface, resulting in its observed distribution. In addition, our model suggests that prior to the asymmetry‐forming impact, the Moon may have had an 182W anomaly compared to the immediate post‐giant impact Earth's mantle, as predicted if the Moon was created through a giant collision with the proto‐Earth.
Seismic Response to Injection Well Stimulation in a High‐Temperature, High‐Permeability Reservoir

Published: May 2019

AbstractFluid injection into the Earth's crust can induce seismic events that cause damage to local infrastructure but also offer valuable insight into seismogenesis. The factors that influence the magnitude, location, and number of induced events remain poorly understood but include injection flow rate and pressure as well as reservoir temperature and permeability. The relationship between injection parameters and injection‐induced seismicity in high‐temperature, high‐permeability reservoirs has not been extensively studied. Here we focus on the Ngatamariki geothermal field in the central Taupō Volcanic Zone, New Zealand, where three stimulation/injection tests have occurred since 2012. We present a catalog of seismicity from 2012 to 2015 created using a matched‐filter detection technique. We analyze the stress state in the reservoir during the injection tests from first motion‐derived focal mechanisms, yielding an average direction of maximum horizontal compressive stress (SHmax) consistent with the regional NE‐SW trend. However, there is significant variation in the direction of maximum compressive stress (σ1), which may reflect geological differences between wells. We use the ratio of injection flow rate to overpressure, referred to as injectivity index, as a proxy for near‐well permeability and compare changes in injectivity index to spatiotemporal characteristics of seismicity accompanying each test. Observed increases in injectivity index are generally poorly correlated with seismicity, suggesting that the locations of microearthquakes are not coincident with the zone of stimulation (i.e., increased permeability). Our findings augment a growing body of work suggesting that aseismic opening or slip, rather than seismic shear, is the active process driving well stimulation in many environments.
The Efficacy of Frost Weathering Processes in Alpine Rockwalls
Authors: Draebing Daniel , Krautblatter Michael 
Published: May 2019

AbstractWeathering processes prepare and trigger rockfall, which is a key agent of alpine landscape evolution and a hazardous process. The relative importance of different weathering processes is hard to decipher; nevertheless, current knowledge assumes a dominant role of frost cracking in eroding alpine rockwalls. This study uses a laboratory approach to simulate volumetric expansion and ice segregation in four alpine rock samples, monitors crack deformation, and quantifies frost weathering efficacy. Our results show that short‐term volumetric expansion in cracks provides stresses up to 10 MPa over hours, while long‐term ice segregation causes stresses of 1 MPa over days. While volumetric expansion in fall can reach critical fracture levels, volumetric expansion in early summer and ice segregation rather approaches subcritical fracture propagation levels. We conclude that subcritical crack propagation is the dominant antecedent process of rockfall initiation, which can be amplified by rare critical cracking due to volumetric expansion.

Published: May 2019

AbstractRising‐tone chorus waves have already been successfully produced in a mirror magnetic field with the use of one‐ and two‐dimensional particle‐in‐cell (PIC) simulations. However, in reality, the background magnetic field in the inner Earth's magnetosphere is a dipole magnetic field, unlike symmetric mirror fields. In this paper, with the two‐dimensional (2‐D) general curvilinear PIC (gcPIC) code, we investigate the generation of rising‐tone chorus waves in the dipole magnetic field configuration. The plasma consists of three components: immobile ions, cold background, and hot electrons. In order to save computational resource, the topology of the magnetic field is roughly equal to that atL = 0.6 RE, although the plasma parameters corresponding to those atL = 6 RE(REis the Earth's radius) are used. Whistler mode waves are first excited around the magnetic equator by the hot electrons with a temperature anisotropy. The excited whistler mode waves propagate almost parallel and antiparallel to the background magnetic field in their source region, which is limited at∣λ ∣ ≤ 3°(whereλis the magnetic latitude). When the waves leave from the source region and propagate toward high latitudes, both their amplitude and wave normal angle become larger. However, the group velocity of the waves is directed toward high latitudes almost along the magnetic field. During such a process, the waves have a frequency chirping, as shown by a rising tone in the frequency‐time spectrogram. To our best knowledge, it is for the first time that rising‐tone chorus are generated in a dipole magnetic field with a PIC simulation.

Published: May 2019

AbstractHigh-density integration technologies with copper (Cu) through-silicon via (TSV) have emerged as viable alternatives for achieving the requisite integration densities for the portable electronics and micro-electro-mechanical systems (MEMSs) package. However, significant thermo-mechanical stresses can be introduced in integrated structures during the manufacturing process due to mismatches of thermal expansion and the mechanical properties between Cu and silicon (Si). The high-density integration demands an interconnection material with a strong mechanical strength and small thermal expansion mismatch. In this study, a novel electroplating method is developed for the synthesis of a graphene-copper (G-Cu) composite with electrochemically exfoliated graphenes. The fabrication and evaluation of the G-Cu composite microstructures, including the microcantilevers and micromirrors supported by the composite, are reported. We evaluated not only the micromechanical properties of the G-Cu composite based on in-situ mechanical resonant frequency measurements using a laser Doppler vibrometer but also the coefficients of thermal expansion (CTE) of the composite based on curvature radius measurements at a temperature range of 20–200 °C. The Young’s modulus and shear modulus of the composite are approximately 123 and 51 GPa, which are 1.25 times greater and 1.22 times greater, respectively, than those of pure Cu due to the reinforcement of graphene. The G-Cu composite exhibits a 23% lower CTE than Cu without sacrificing electrical conductivity. These results show that the mechanically strengthened G-Cu composite with reduced thermal expansion is an ideal and reliable interconnection material instead of Cu for complex integration structures.
Separation of spermatozoa from erythrocytes using their tumbling mechanism in a pinch flow fractionation device

Published: May 2019

AbstractMen suffering from azoospermia can father a child, by extracting spermatozoa from a testicular biopsy sample. The main complication in this procedure is the presence of an abundance of erythrocytes. Currently, the isolation of the few spermatozoa from the sample is manually performed due to ineffectiveness of filtering methods, making it time consuming and labor intensive. The spermatozoa are smaller in both width and height than any other cell type found in the sample, with a very small difference compared with the erythrocyte for the smallest, making this not the feature to base the extraction on. However, the length of the spermatozoon is 5× larger than the diameter of an erythrocyte and can be utilized. Here we propose a microfluidic chip, in which the tumbling behavior of spermatozoa in pinched flow fractionation is utilized to separate them from the erythrocytes. We show that we can extract 95% of the spermatozoa from a sample containing 2.5% spermatozoa, while removing around 90% of the erythrocytes. By adjusting the flow rates, we are able to increase the collection efficiency while slightly sacrificing the purity, tuning the solution for the available sample in the clinic.
