Parenting and Temperament Prior to September 11, 2001, and Parenting Specific to 9/11 as Predictors of Children's Posttraumatic Stress Symptoms Following 9/11

Parenting is related to children's adjustment, but little research has examined the role of parenting in children's responses to disasters. This study describes parenting responses specific to the 9/11 terrorist attacks and examines pre-9/11 parenting, child temperament, and 9/11-specific parenting as predictors of children's posttraumatic stress (PTS) symptoms among children geographically distant from the attack locations. A community sample of children and parents (n = 137, ages 9–13 years) participating in an ongoing study were interviewed 1 month following 9/11. Parents reported engaging in a number of parenting responses following 9/11. Pre-9/11 acceptance and 9/11-specific, self-focused parental responses predicted PTS symptoms. Pre-9/11 parenting and temperament interacted to predict PTS symptoms, suggesting that parenting and temperament are important prospective predictors of children's responses to indirect exposure to disasters.
Discrete composite control for piezoelectric actuator systems

This paper considers the precise control of piezoelectric actuator systems with hysteresis nonlinearity. First, the piezoelectric nonlinearity model is described by a quasi-static hysteresis which is cascaded a non-hysteretic dynamics. Next, A discrete Preisach model represents the quasi-static hysteresis and a composite controller is proposed which consists of inverse model-based control (IMC) and discrete sliding mode control (DSMC) for piezoelectric actuator systems. In order to reduce the chattering, a hyperbolic tangent function replace signum function in DSMC. Moreover, a selector is proposed to select the appropriate input between the output of IMC and DSMC for the quasi-static hysteresis to promote the accuracy of the control strategy and the response speed. Finally, the stability of this piezoelectric system is guaranteed by a Lyapunov-based approach and the numerical simulation demonstrates the effectiveness of the proposed control strategy.
Constrained Community Detection in Social Networks

Community detection in networks is the process by which unusually well-connected sub-networks are identified–a central component of many applied network analyses. The paradigm of modularity quality function optimization stipulates a partition of the network’s vertexes that maximizes the difference between the fraction of edges within communities and the corresponding expected fraction if edges were randomly allocated among all vertex pairs while conserving the degree distribution. The modularity quality function incorporates exclusively the network’s topology and has been extensively studied whereas the integration of constraints or external information on community composition has largely remained unexplored. We define a greedy, recursive-backtracking search procedure to identify the constitution of high-quality network communities that satisfy the global constraint that each community be comprised of at least one vertex among a set of so-called special vertexes and apply our methodology to identifying health care communities (HCCs) within a network of hospitals such that each HCC consists of at least one hospital wherein at least a minimum number of cardiac defibrillator surgeries were performed. This restriction permits meaningful comparisons in cardiac care among the resulting health care communities by standardizing the distribution of cardiac care across the hospital network.
Selective vulnerability of dentate hilar neurons following traumatic brain injury: a potential mechanistic link between head trauma and disorders of the hippocampus

Despite intensive study, the neurobiological basis of epilepsy and persistent memory impairment following traumatic head injury remains unknown. Since abnormalities of the hippocampus are known to be associated with temporal lobe seizures and memory dysfunction, we investigated the effects of experimental traumatic brain injury on hippocampal structure and function in the rat. Using a model of fluid- percussion injury, we have discovered that neurons of the dentate hilus are vulnerable to a brief, unilateral impact to the extradural surface of the brain. One week after trauma, there was a dramatic reduction in hilar neurons ipsilateral to the impact, and a milder but significant decrease in neurons on the contralateral side as well. This neuronal loss was highly selective since adjacent dentate granule and pyramidal neurons appeared relatively unaffected. Immunocytochemistry showed that the hilar cell loss included a loss of somatostatin-immunoreactive neurons, and degeneration stains provided evidence that irreversible hilar injury occurred within 4 hr of impact. To assess the functional effects of the hilar damage, dentate granule cell field potentials were measured in response to perforant path stimulation. This revealed abnormal dentate granule cell hyperexcitability at 2.0 Hz stimulation in many of the injured animals. The presence of abnormal hyperexcitability correlated with the loss of hilar neurons. Thus, a momentary impact to the surface of the brain can cause selective, bilateral hippocampal injury with associated abnormalities in dentate gyrus physiology. Furthermore, the pattern of cell loss is similar to that observed in some patients with temporal lobe epilepsy. (ABSTRACT TRUNCATED AT 250 WORDS)
Pheromone puff trajectory and upwind flight of male gypsy moths in a forest

ABSTRACT. Pheromone released from a point source beneath a forest canopy usually follows a non‐linear trajectory as demonstrated by the paths of small, neutrally‐buoyant, helium‐filled balloons or puffs of smoke. Mark‐recapture experiments show that few male gypsy moths (Lymantria dispar L.) follow a pheromone plume over distances greater than 80 m even though they can easily detect pheromone at that distance as indicated by wingfanning assay. The directional consistency of successive puffs of pheromone appears more important than the linearity of their trajectories in enabling males to locate a pheromone source.
Notice of RetractionResearch on the Governance Effect of Board Size: An New Explanation from Performance Variability

Beside the performance absolute value is an important criterion to evalue the governance effect of board of directors, performance variability is also an important criterion. This paper explores the relationship between board of directors' size and performance variability in Chinese listed companies from 2000 to 2007. We find that large board can reduce the variability of performance. Further exploration shows that board size can indirectly reduce the variability of performance by reducing the variability of operating accruals, non-regular income and operating discretional accrual.
International Conference on Information Fusion ( FUSION ) Enhanced Image Feature Extraction for Object Tracking *

A feature-based technique is presented for 3D motion and structure estimation of rigid objects from a sequence of images. Considered is a feature-based rigid object representation which is more complete as compared to previous techniques. In this approach the features provide information regarding the location and type ofsignificant object components and connections. A robust enhanced Hough transform (HT) approach is proposed for line andjunction detection. Based on a perspective projection imaging model the extracted feature points of an object are used for estimating its 3D motion and structure parameters by means of the unscented Kalman filter (UKF). The performances of the HTbasedfeature extractor and the UKF are illustrated via simulation results.
Power-aware design of the optical interconnect for future data centers

The volume of traffic carried on the Optical Transport Network (OTN) is continuously growing, not only due to the increase of new services, new applications, and the number of both connected users and smart devices, but also owing to the rapidly growing Data Center Interconnect (DCI) market. As a result, telecom operators need to upgrade their transport networks to cope with these new traffic requirements. This tremendous increase in bandwidth demand will also introduce energy bottlenecks in OTNs. The telecommunication networks' significant Greenhouse Gas Emissions (GGE) is another challenge that must be addressed in OTN design and planning policies. Thus, energy-efficient OTN architectures are currently attracting the attention of telecom operators. The candidate OTN architectures are: (1) the conventional Dense Wavelength Division Multiplexing (DWDM) fixed grid with high Single Line Rates (SLRs); (2) the conventional DWDM fixed grid adopting Mixed Line Rates (MLRs); and (3) the Elastic Optical Network (EON) or flexigrid-based architecture which is enabled by the Optical Orthogonal Frequency Division Multiplexing (O-OFDM) technique. This paper evaluates the power consumption of the abovementioned OTN architectures under different traffic loads and patterns, as well as different network physical topologies. In order to perform the evaluation, new heuristic algorithms are specifically developed for the green design and planning of data center optical interconnects.
Tensile tests of ITER TF conductors jacket materials

The set of very tough requirements has been formulated for TF jacket materials with extremely high plasticity at liquid helium temperature. The stainless steel 316LN-IG is recommended to be used for TF jacket tubes. Samples of 316LN-IG tubes (whole tubes and sub-size samples) made of the material from the same electro slag remelt have been tested in different conditions - as received tubes and tubes after prescribed compaction, 2.5% deformation at room temperature and heat treatment at 650 0C, 200 hours. The tensile tests were carried out at room, liquid nitrogen and liquid helium temperatures down to 4.2 K, meeting corresponding ASME and ASTM requirements. The low temperature testing devices are described. The tests results for sub-size samples and whole tubes show that the latter tests are considerably more representative and important for butt weld qualification at LHe temperature. It was observed that the ferromagnetic properties of all samples and especially of butt welds increase with lowering the t.
Pluggable Component: A Pattern for Interactive System Configuration

In many applications, especially in frameworks, it is necessary to exchange components. The standard approach to achieve this is to use an abstract class as the interface against which the application is programmed, and several concrete subclasses to supply implementations for the abstract interface class. There are several GOF patterns that deal with this kind of component exchange (see Related Patterns section). There, the classes must be available at compile time and they are instantiated according to program state or user selection. However, there are situations when this degree of flexibility is not enough.
UACAP: A Unified Auxiliary Channel Authentication Protocol

Authenticating spontaneous interactions between devices and users is challenging for several reasons: the wireless (and therefore invisible) nature of device communication, the heterogeneous nature of devices, and lack of appropriate user interfaces in mobile devices, and the requirement for unobtrusive user interaction. The most promising approach that has been proposed in literature involves the exploitation of the so-called auxiliary channels for authentication to bridge the gap between usability and security. This concept has spawned the independent development of various authentication methods and research prototypes, that, unfortunately, remain hard to compare and interchange and are rarely available to potential application developers. We present a novel, unified cryptographic authentication protocol framework (UACAP) to unify these approaches on using auxiliary channels and analyze its security properties. This protocol and a selection of auxiliary channels aimed at authentication of mobile devices has been implemented and released in an open-source ubiquitous authentication toolkit (OpenUAT). We also present an initial user study evaluating four of these channels.
Sensitive period for sensorimotor integration during vocal motor learning.

Sensory experience during sensitive periods in development may direct the organization of neural substrates, thereby permanently influencing subsequent adult behavior. We report a sensitive period during the imitative motor learning phase of sensorimotor integration in birdsong development. By temporarily and reversibly blocking efference to the vocal muscles, we disrupted vocal motor practice during selected stages of song development. Motor disruption during prolonged periods early in development, which allows recovery of vocal control prior to the onset of adult song, has no effect on adult song production. However, song disruption late in development, during the emergence of adult song, results in permanent motor defects in adult song production. These results reveal a decreased ability to compensate for interference with motor function when disturbances occur during the terminal stage of vocal motor development. Temporary disruption of syringeal motor control in adults does not produce permanent changes in song production. Permanent vocal aberrations in juveniles are evident exclusively in learned song elements rather than nonlearned calls, suggesting that the sensitive period is associated with motor learning.
Effects of dynamic exercise intensity on the activation of hormone‐sensitive lipase in human skeletal muscle

It has been proposed that hormone‐sensitive lipase (HSL) regulates intramuscular triacylglycerol hydrolysis in skeletal muscle. The primary purpose of this study was to examine the early activation of HSL and the changes in the putative intramuscular and hormonal regulators of HSL activity at various aerobic exercise intensities. Eight male subjects cycled for 10 min at power outputs corresponding to 30, 60 and 90 % peak oxygen uptake (V̇O2,peak). Muscle samples were obtained at rest and following 1 and 10 min of exercise. Intramuscular triacylglycerol (mean ±s.e.m.: 24.3 ± 2.3 mmol (kg dry mass (DM))‐1), long‐chain fatty acyl CoA (13.9 ± 1.4 µmol (kg DM)‐1) and HSL activity (1.87 ± 0.07 mmol min‐1 (kg DM)‐1)) were not different between trials at rest. HSL activity increased at 1 min of exercise at 30 and 60 % V̇O2,peak, and to a greater extent at 90 % V̇O2,peak. HSL activity remained elevated after 10 min of exercise at 30 and 60 % V̇O2,peak, and decreased at 90 % V̇O2,peak from the rates observed at 1 min (1 min: 3.41 ± 0.3 mmol min‐1 (kg DM)‐1; 10 min: 2.92 ± 0.26 mmol min‐1 (kg DM)‐1), P < 0.05). There were no effects of exercise power output or time on long‐chain fatty acyl CoA content. At 90 % V̇O2,peak, skeletal muscle contents of ATP and phosphocreatine were decreased (P < 0.05), and free ADP and free AMP were increased (P < 0.05) during exercise. No changes in these metabolites occurred at 30 % V̇O2,peak and only modest changes were observed at 60 % V̇O2,peak. Plasma adrenaline increased (P < 0.05) during exercise at 90 % V̇O2,peak only. These data suggest that a factor related to the onset of exercise (e.g. Ca2+) activates HSL early in exercise. Given the activation of HSL early in exercise, at a time when intramuscular triacylglycerol hydrolysis and fat oxidation are considered to be negligible, we propose that the control of intramuscular triacylglycerol hydrolysis is not solely related to the level of HSL activation, but must also be regulated by postactivational factors.
Clinical features of myocardial infarction and myocarditis in young adults: a retrospective study

Objectives To evaluate the prevalence and clinical presentation of myocardial infarction (MI) and myocarditis in young adults presenting with chest pain (CP) and an elevated serum troponin I (TnI) to the emergency department (ED). Design Retrospective, observational, single-centre study. Participants All consecutive patients 18–40 years old admitted to the ED for CP with an elevated TnI concentration. Primary outcome measures Prevalence of MI, myocarditis and the characterisation of clinical presentation. Results 1588 patients between 18 and 40 years old were admitted to the ED with CP during 30 consecutive months. 49 (3.1%) patients with an elevated TnI (>0.09 μg/l) were included. 32.7% (16/49) were diagnosed with MI (11 ST-elevation myocardial infarction (STEMI) and 5 non-ST-elevation myocardial infarction (NSTEMI)) and 59.2% (29/49) with myocarditis. Compared with patients with myocarditis, MI patients were older (34.1±3.8 vs 26.9±6.4, p=0.0002) with more cardiovascular risk factors (mean 2.06 vs 0.69). Diabetes (18.8% vs 0%, p=0.0039), dyslipidaemia (56.2% vs 3.4%, p<0.0001) and family history of coronary artery disease (CAD) (37.5% vs 10.3% p=0.050) were associated with MI. Fever or recent viral illness were present in 75.9% (22/29) of patients with myocarditis, and in 0% of MI patients (p<0.0001). During follow-up, two patients with myocarditis were re-admitted for CP. Conclusions In this study, 32.7% of patients <40-year-old admitted to an ED with CP and elevated TnI had a diagnosis of MI. Key distinctive clinical factors include diabetes, dyslipidaemia, family history of CAD and fever or recent viral illness.
Maximum likelihood structure and motion estimation integrated over time

Least squares minimization of the differential epipolar constraint is a fast and efficient technique to estimate structure and motion for pair of views. Previous work in this area showed how unbiased and consistent estimates could be obtained minimizing the squared errors. However it implicitly assumes that the errors along the x and y directions are identical and uncorrelated. This is rarely the case for real data, due to the aperture problem. Instead, one should minimize the covariance weighted squared error Moreover when dense sequences are acquired, further robustness can be achieved by integrating the reconstruction of structure over time. The paper has two main contributions: (i) we show that the minimization of the weighted squared errors (i.e. maximum-likelihood estimate) outperforms the more traditional approach of un-weighted least squares, (ii) we show how structure estimation can be integrated over time in a multi-view approach that drastically improves estimates.
Molecular Drivers of Pancreatic Cancer Pathogenesis: Looking Inward to Move Forward

Pancreatic cancer (PC) continues to rank among the most lethal cancers. The consistent increase in incidence and mortality has made it the seventh leading cause of cancer-associated deaths globally and the third in the United States. The biggest challenge in combating PC is our insufficient understanding of the molecular mechanism(s) underlying its complex biology. Studies during the last several years have helped identify several putative factors and events, both genetic and epigenetic, as well as some deregulated signaling pathways, with implications in PC onset and progression. In this review article, we make an effort to summarize our current understanding of molecular and cellular events involved in the pathogenesis of pancreatic malignancy. Specifically, we provide up-to-date information on the genetic and epigenetic changes that occur during the initiation and progression of PC and their functional involvement in the pathogenic processes. We also discuss the impact of the tumor microenvironment on the molecular landscape of PC and its role in aggressive disease progression. It is envisioned that a better understanding of these molecular factors and the mechanisms of their actions can help unravel novel diagnostic and prognostic biomarkers and can also be exploited for future targeted therapies.
Branded with a scarlet "C": cheaters in a gaming social network

Online gaming is a multi-billion dollar industry that entertains a large, global population. One unfortunate phenomenon, however, poisons the competition and the fun: cheating. The costs of cheating span from industry-supported expenditures to detect and limit cheating, to victims' monetary losses due to cyber crime. This paper studies cheaters in the Steam Community, an online social network built on top of the world's dominant digital game delivery platform. We collected information about more than 12 million gamers connected in a global social network, of which more than 700 thousand have their profiles flagged as cheaters. We also collected in-game interaction data of over 10 thousand players from a popular multiplayer gaming server. We show that cheaters are well embedded in the social and interaction networks: their network position is largely indistinguishable from that of fair players. We observe that the cheating behavior appears to spread through a social mechanism: the presence and the number of cheater friends of a fair player is correlated with the likelihood of her becoming a cheater in the future. Also, we observe that there is a social penalty involved with being labeled as a cheater: cheaters are likely to switch to more restrictive privacy settings once they are tagged and they lose more friends than fair players. Finally, we observe that the number of cheaters is not correlated with the geographical, real-world population density, or with the local popularity of the Steam Community.
A user-level checkpointing library for POSIX threads programs

Several user-level checkpointing libraries that checkpoint Unix processes have been developed. However they do not support multithreaded programs. This paper describes a user-level checkpointing library to checkpoint multithreaded programs that use the POSIX threads library provided by Solaris 2. Experiments with programs from the SPLASH-2 benchmark suite showed a 3% to 10% increase in execution time with checkpointing enabled, plus an additional overhead for saving the program's state. The checkpointing library described here is available at http://www.dcs. uky.edu//sup /spl sim//chkpt/.
Diagnosis of Induction Machines' Rotor Faults in Time-Varying Conditions

Motor current signature analysis is the reference method for the diagnosis of induction machines' rotor faults; however, in time-varying conditions, it fails as slip and speed vary, and, thus, sideband components are spread in a bandwidth that is proportional to the variation. Variable speed drive applications are common in the aerospace, appliance, railway, and automotive industries and also in electric generators for wind turbines. In this paper, a simple and effective method is presented that allows the diagnosis of rotor faults for induction machine drives in time-varying conditions. It is tailored to direct rotor flux field-oriented controlled drives, where the control system provides suitable signals that are exploited for the demodulation to a constant frequency of time-varying signatures related to the rotor faults. Simulations and experiments are reported to validate the proposed method on a critical speed transient.
General first-order TRE model when using a coordinate reference frame for rigid point-based registration

Rigid point-based registration technique is widely used in many aspects of image-guided surgery (IGS). Estimating target registration error (TRE) statistics considering a coordinate reference frame (CRF) is of essential value for applications such as optical tracking and image registration. In this paper, we extend the TRE estimation algorithm relative to a CRF to general fiducial localization error (FLE) case. The Monte Carlo simulation results demonstrate the algorithm's effectiveness for both homogeneous and inhomogeneous FLE cases.
