FOAM -ON -TILE IMPACT MODELING FOR THE STS-107 INVESTIGATION

Following the breakup of the Space Shuttle Columbia during reentry , a NASA/Contractor impact modeling team was formed to examine the probable damage inflicted on Orbiter Thermal Protection System (TPS) elements by impact of External Tank (ET) cryoinsulation debris . Our team was tasked to apply “physics based ” analysis techniques to help determine parameters of interest for the experimental test program in preparation at Southwest Research Institute (SwRI), and to utilize validated codes to investigate the full range of impact scenarios beyond what could be tested within a reasonable timeframe. The term “physics -based” was used to indicate that t he physics of the event – projectile mass, velocity, and impact angle – would be used to develop the transient loading profile. The team had members from several NASA centers, Sandia National Laboratory, academia, and private industry. The analysis team r eported to the Orbiter Vehicle Engineering Working Group, gave input to the impact test team, and presented pre -test predictions at the Main Landing Gear Door and Wing Leading Edge impact test readiness reviews. The authors formed a working sub -group with in the larger analysis team to apply the Smooth Particle Hydrodynamics code SPHC to the damage estimation problem. We obtained material properties needed to numerically model the TPS tiles and ET foam from tests performed by other organization s w ithin the analysis team, and from existing materials data bases . We constructed t wo - and three -dimensional tile models , and developed a model o f BX -250 foam , which includ ed porous compression, elastic rebound, and surface erosion characteristics . We validated our code results for the tile damage and foam behavior through extensive comparison with SwRI foam -on -tile impact experiments carried out in 1999. These tests involved small projectiles striking individual tiles and small tile arrays. The foam used in the 199 9 SwRI tests was a different cryoinsulation from that used on the ET, but with similar density and mechanical propert ies . Following detailed comparison of experimental and model results , we simulated impacts of larger foam projectiles on examples of tile systems used on the Orbit er. Results for impacts on the M ain Landing Gear Door are presented in this paper, i ncluding effects of impacts at several angles, and of rapidly rotating projectiles. General results suggest that foam impacts on tiles at about 500 mph could cause appreciable damage if the impact angle is greater than about 20 degrees. Some variations of the foam properties, such as increased brittleness or increased density could increase damage in some cases. Rotation up to 17 rps failed to incre ase the damage for the two cases considered. This does not rule out other cases in which the rotational energy might lead to an increase in tile damage, but suggests that in most cases rotation will not be an important factor. BACKGROUND
Making Stochastic Neural Networks from Deterministic Ones

It has been believed that stochastic feedforward neural networks (SFNN) have several advantages beyond deterministic deep neural networks (DNN): they have more expressive power allowing multi-modal mappings and regularize better due to their stochastic nature. However, training SFNN is notoriously harder. In this paper, we aim at developing efficient training methods for large-scale SFNN, in particular using known architectures and pre-trained parameters of DNN. To this end, we propose a new intermediate stochastic model, called Simplified-SFNN, which can be built upon any baseline DNN and approximates certain SFNN by simplifying its upper latent units above stochastic ones. The main novelty of our approach is in establishing the connection between three models, i.e., DNN -> Simplified-SFNN -> SFNN, which naturally leads to an efficient training procedure of the stochastic models utilizing pre-trained parameters of DNN. Using several popular DNNs, we show how they can be effectively transferred to the corresponding stochastic models for both multi-modal and classification tasks on MNIST, TFD, CIFAR-10, CIFAR-100 and SVHN datasets. In particular, our stochastic model built from the wide residual network has 28 layers and 36 million parameters, where the former consistently outperforms the latter for the classification tasks on CIFAR-10 and CIFAR-100 due to its stochastic regularizing effect.
The Emotional Dynamics of Narcissism: Inflated by Pride, Deflated by Shame

Since its introduction into the psychological literature, narcissism has been conceptualized as an emotional disorder—a result of excessive pride and shame. Following Freud (1914/1957), Kernberg (1975) argued that the central psychological process underlying the disorder— identifi cation with an idealized ego—necessarily leads to pride. Kohut (1971) placed greater emphasis on shame, viewing it as the typical response to the “narcissistic wound”—a loss of grandiosity thought to occur in the narcissist’s early development. Lewis (1981) also viewed shame as central, but as an etiological factor underlying narcissism’s development, rather than a response to the narcissistic wound. In this view, narcissism is essentially a shamecoping response mechanism (Morrison, 1989). Broucek (1982) integrated both of these perspectives, arguing that shame is a response to the narcissistic wound and a stimulus to narcissistic selfaggrandizement. Eventually, shame became pinpointed as the “keystone” affect in narcissism (Broucek, 1982; Wright, O’Leary, & Balkin, 1989). Thus, although socialpersonality researchers have only recently begun to emphasize the specifi c emotions underlying narcissism, clinicians and psychodynamic theorists have long argued that shame and pride critically shape this personality process. This emotionfocused perspective leads to one of the paradoxes of narcissism: how do two seemingly opposite emotions interact to produce a coherent personality?
A MULTI-WAVELENGTH MASS ANALYSIS OF RCS2 J232727.6-020437, A ∼3 × 1015 M⊙ GALAXY CLUSTER AT z = 0.7

We present an initial study of the mass and evolutionary state of a massive and distant cluster, RCS2 J232727.6-020437. This cluster, at z = 0.6986, is the richest cluster discovered in the RCS2 project. The mass measurements presented in this paper are derived from all possible mass proxies: X-ray measurements, weak-lensing shear, strong lensing, Sunyaev–Zel’dovich effect decrement, the velocity distribution of cluster member galaxies, and galaxy richness. While each of these observables probe the mass of the cluster at a different radius, they all indicate that RCS2 J232727.6−020437 is among the most massive clusters at this redshift, with an estimated mass of M 200 ∼ 3 × 10 15 h 70 − 1 ? > M ⊙ ? > . In this paper, we demonstrate that the various observables are all reasonably consistent with each other to within their uncertainties. RCS2 J232727.6−020437 appears to be well relaxed—with circular and concentric X-ray isophotes, with a cool core, and no indication of significant substructure in extensive galaxy velocity data.
Benefits of Service-Learning for Freshmen College Students and Elementary School Children.

Freshman honors students in a service-learning course tutored low- income English Language Learning kindergartners, first-, and second-graders in reading. We conducted two separate data collections, one assessing college students' attitudes and motives (Study 1) and one exploring the benefits for elementary school children (Study 2). We measured changes in college students' motivations for volunteering and social attitudes, and we measured changes in children's reading performance and achievement goals. Comparisons with non- service-learning college students revealed that the service-learning students volunteered more hours, showed larger gains in esteem and protective motives (volunteering made them feel better about themselves and helped them cope with personal problems), and showed a marginally significant increase in motivation to volunteer in order to promote professional growth. We found a positive correlation between hours tutored and increases in children's reading scores, and the children showed increases in adaptive achievement goals. Although service- learning benefits for children were non-significant due to small sample size, findings suggest that benefits of the service-learning project were reciprocal.
Enhancing array stochastic resonance in ensembles of excitable systems

A summing network of FitzHugh–Nagumo model neurons, immersed in the background of both external noise and internal noise, is studied in the context of array stochastic resonance. An aperiodic Gaussian stimulus, assisted by collective internal array noise, stimulates the summing network for a more efficient response. This form of array stochastic resonance can be characterized by a correlation coefficient for an aperiodic input signal. Moreover, the correlation gain of the ensembles of neuronal models is investigated for finite and infinite array sizes. The nonmonotonic behavior of the correlation gain and the regions of the correlation gain beyond unity, i.e. the two main features of array SR, are demonstrated numerically and theoretically. These results suggest that certain levels of both external noise and internal noise contribute in a beneficial way to the neuronal coding strategy.

From Interstellar Dust to Comets: Infrared Emission from Comet Hale-Bopp (C/1995 O1)

The 3-20 μm IR thermal emission spectrum of comet Hale-Bopp (C/1995 O1) at a heliocentric distance of rh=1.15 AU has been calculated using fluffy aggregates of silicate core-organic refractory mantle interstellar dust as the comet dust model. The principal dust properties, similar to those obtained for other comets, provide good fits to the observation. Our results are significantly different from the general opinion that Hale-Bopp is rich in submicron grains. The mean grain masses derived here are 2-3 orders of magnitude higher than those estimated from the empirical superheat method or from the IR emission modeling, both of which use compact silicate/carbon particles. It has been shown that the IR emission alone cannot give a reliable dust production rate. We have also modeled the crystalline silicate emission spectrum.
Study of Duct Characteristics Deduced from Low Latitude Ground Observations of Day-Time Whistler at Jammu

Propagation characteristics of low latitude whistler duct characteristics have been investigated based on day-time measurements at Jammu. The morphogical characteristics of low latitude whistlers are discussed and compared with characteristics of middle and high latitude whistlers. The Max. electron density (Nm) at the height of the ionosphere obtained from whistler dispersion comes out to be higher than that of the background which is in accordance with the characteristics of whistler duct. The equivalent width is found to be close to the satellite observations and the characteristics of whistler duct in low latitude ionosphere are similar to those in middle and high latitude ionosphere. The width of ducts estimated from the diffuseness of the whistler track observed during magnetic storm is found to lie in the range of 50 - 200 Km.
TIME-DOMAIN MEASUREMENT OF TIME-CODED UWB CHIPLESS RFID TAGS

Chipless ultra-wideband (UWB) has been proposed as a low-cost alternative for radiofrequency identiflcation (RFID). In this paper, a comprehensible theoretical introduction to time-domain operation of a UWB RFID tag is described, and a circuit model is proposed. For commercial applications low-cost RFID readers are demanded. To this end, this paper addresses the measurement of time-coded UWB chipless tags for RFID in time domain. Two difierent setups to detect time-coded tags are presented, one based on commercial UWB impulse radar (IR) and the other based on a vector network analyzer (VNA). The experimental results show the feasibility of using an IR-UWB radar as a UWB RFID reader, achieving very good read ranges.
A Chandra look at the X-ray faint millisecond pulsars in the globular cluster NGC 6752

We combine new and archival Chandra observations of the globular cluster NGC 6752 to create a deeper X-ray source list, and study the faint radio millisecond pulsars (MSPs) of this cluster. We detect four of the five MSPs in NGC 6752, and present evidence for emission from the fifth. The X-rays from these MSPs are consistent with thermal emission from the neutron star surfaces, with significantly higher fitted blackbody temperatures than other globular cluster MSPs (though we cannot rule out contamination by nonthermal emission or other X-ray sources). NGC 6752 E is one of the lowest-L_X MSPs known, with L_X(0.3-8 keV)=1.0+0.9-0.5*10^30 ergs/s. We check for optical counterparts of the three isolated MSPs in the core using new HST ACS images, finding no plausible counterparts, which is consistent with their lack of binary companions. We compile measurements of L_X and spindown power for radio MSPs from the literature, including errors where feasible. We find no evidence that isolated MSPs have lower L_X than MSPs in binary systems, omitting binary MSPs showing emission from intrabinary wind shocks. We find weak evidence for an inverse correlation between the estimated temperature of the MSP X-rays and the known MSP spin period, consistent with the predicted shrinking of the MSP polar cap size with increasing spin period.
Stereo Algorithm with Anisotropic Reaction-Diffusion Systems

The computer vision research aims at a better understanding of the human visual system and building artificial visual systems. Vision researchers in psychology and physiology have explored biological visual systems including the human vision, and obtained much knowledge on nature and architecture of their visual information processing. For example, some of previous results in experimental psychology suggested integration of several visual cues [1–3], and others of them showed evidence of anisotropy in the stereo depth perception [4, 5]. Mathematical models and computer algorithms developed according to previous experimental results help us to understand the human visual system and to build artificial visual systems.
Sow and litter performance following farrowing induction with prostaglandin: Effect of adjunct treatments with dexamethasone or oxytocin

Materials and methods: In Experiment One, 144 sows were induced with two injections of PGF 6 hours apart (split dose) with or without injection of 20 mg DEX with the second PGF. Interval from initial PGF to farrowing, duration of farrowing, litter size born alive, number of stillbirths, and piglet weight gain to 10 days of age were recorded. In Experiment Two, 106 sows were induced with single or split-dose injections of PGF with or without injection of 20 IU oxytocin 24 hours after initial PGF. Time to onset and duration of farrowing were recorded, as were requirement for manual intervention, total litter size born, and incidence of stillbirths.
WHAT ROLE DOES PSYCHOLOGICAL NEED SATISFACTION PLAY IN MOTIVATING EXERCISE PARTICIPATION?

The purpose of this study was to examine Vallerand‟s (2001) contention that perceptions of psychological need satisfaction underpin the endorsement of different motives, which in turn, predicts behavioural intentions in the context of exercise. Participants (N = 176; 51.2% female) involved in a group-based intramural event completed a self-administered cross-sectional survey comprised of demographic questions, the Psychological Need Satisfaction in Exercise Scale (PNSE; Wilson et al., 2006), the Behavioural Regulation in Exercise Questionnaire (BREQ; Mullan et al., 1997), and a behavioural intention scale (Courneya & McAuley, 1993). Bivariate correlations indicated stronger relationships between fulfillment of the psychological needs for competence, autonomy, and relatedness with identified and intrinsic regulations (r‟s ranged from 0.47 to 0.67) compared to external and introjected regulations (r‟s ranged from -0.30 to 0.19). Multivariate analysis using structural equation modeling supported the tenability of a model explaining behavioural intentions (R 2 = 0.17) as a function of a person‟s relative autonomy motivational index (  = 41) which in turn was predicted by perceived competence (  = 0.25), autonomy ( = 0.53), and relatedness ( = -0.12) in exercise contexts (χ = 399.47; df = 183; CFI = 0.92; IFI = 0.92; RMSEA * Correspondence concerning this manuscript can be sent to: Philip M.

Overall, the results of the present investigation partially support Vallerand‟s argument regarding the sequences that shape motivational processes in exercise contexts. Furthermore, the results of the present investigation provide support for the importance of psychological need satisfaction for internalized motivation in an applied context which is in line with more general arguments set forth within the framework of self-determination theory (Deci & Ryan, 1985; 2002).
Stress Hyperglycemia

Injury and destruction of the islets precede the onset of clinical hyperglycemia in Type 1 diabetes mellitus (DM). This represents the activation of an autoimmune state followed by an imbalance between T-helper and T-suppressor cells and the susceptibility or resistance of the β-cells to injury. Because some stress hormones (particularly cortisol) are known to modulate the immune system and others to alter islet β-cell activity (epinephrine, glucagon, cortisol), there has been speculation about the role of such modulation on the process of islet injury. Thus, neurohormonal changes associated with stress have been proposed as one of the environmental factors that interact with hereditary factors known to be associated with the risk of developing Type 1 diabetes.
Bulk and surface Rashba splitting in single termination BiTeCl

By angle-resolved photoemission spectroscopy (ARPES) we observe a giant Rashba-type spin splitting in the electronic bulk conduction and valence bands of the semiconductor BiTeCl. This material belongs to the group of bismuth tellurohalides BiTeX (X = Cl,Br,I) which are layered non-centrosymmetric materials with strong spin–orbit interaction. By photon energy-dependent ARPES, we separate the bulk and surface contribution of the electronic structure and show that the tellurium-terminated (0001) crystal surface hosts spin-split two-dimensional surface states. On the chlorine-terminated surface at the opposite side of the crystal no surface states are observed due to photon-induced surface chemistry.
Improving Moderator Responsiveness in Online Peer Support Through Automated Triage

Background Online peer support forums require oversight to ensure they remain safe and therapeutic. As online communities grow, they place a greater burden on their human moderators, which increases the likelihood that people at risk may be overlooked. This study evaluated the potential for machine learning to assist online peer support by directing moderators’ attention where it is most needed. Objective This study aimed to evaluate the accuracy of an automated triage system and the extent to which it influences moderator behavior. Methods A machine learning classifier was trained to prioritize forum messages as green, amber, red, or crisis depending on how urgently they require attention from a moderator. This was then launched as a set of widgets injected into a popular online peer support forum hosted by ReachOut.com, an Australian Web-based youth mental health service that aims to intervene early in the onset of mental health problems in young people. The accuracy of the system was evaluated using a holdout test set of manually prioritized messages. The impact on moderator behavior was measured as response ratio and response latency, that is, the proportion of messages that receive at least one reply from a moderator and how long it took for these replies to be made. These measures were compared across 3 periods: before launch, after an informal launch, and after a formal launch accompanied by training. Results The algorithm achieved 84% f-measure in identifying content that required a moderator response. Between prelaunch and post-training periods, response ratios increased by 0.9, 4.4, and 10.5 percentage points for messages labelled as crisis, red, and green, respectively, but decreased by 5.0 percentage points for amber messages. Logistic regression indicated that the triage system was a significant contributor to response ratios for green, amber, and red messages, but not for crisis messages. Response latency was significantly reduced (P<.001), between the same periods, by factors of 80%, 80%, 77%, and 12% for crisis, red, amber, and green messages, respectively. Regression analysis indicated that the triage system made a significant and unique contribution to reducing the time taken to respond to green, amber, and red messages, but not to crisis messages, after accounting for moderator and community activity. Conclusions The triage system was generally accurate, and moderators were largely in agreement with how messages were prioritized. It had a modest effect on response ratios, primarily because moderators were already more likely to respond to high priority content before the introduction of triage. However, it significantly and substantially reduced the time taken for moderators to respond to prioritized content. Further evaluations are needed to assess the impact of mistakes made by the triage algorithm and how changes to moderator responsiveness impact the well-being of forum members.
