Two distinct populations of dark comets delineated by orbits and sizes.

Small bodies are capable of delivering essential prerequisites for the development of life, such as volatiles and organics, to the terrestrial planets. For example, empirical evidence suggests that water was delivered to the Earth by hydrated planetesimals from distant regions of the Solar System. Recently, several morphologically inactive near-Earth objects were reported to experience significant nongravitational accelerations inconsistent with radiation-based effects, and possibly explained by volatile-driven outgassing.

Acceleration of 1I/'Oumuamua from radiolytically produced H in HO ice.

In 2017, 1I/'Oumuamua was identified as the first known interstellar object in the Solar System. Although typical cometary activity tracers were not detected, 'Oumuamua showed a notable non-gravitational acceleration. So far, there has been no explanation that can reconcile these constraints.

Methods: Data from patients treated with the NexGen PS TKA between January 2003 and December 2005 with a minimal follow-up of 15 years was collected from a prospectively collected database.

Treating Heel Pain in Adults: A Randomized Controlled Trial of Hard vs Modified Soft Custom Orthotics and Heel Pads.

Objectives: This study compared the effectiveness of soft vs hard orthotics in treating heel pain and plantar fasciitis in adults. It also compared the level of function after orthotic use, cost, and number of visits for orthotics and explored whether age was a factor in orthotic effectiveness.

Design: Randomized controlled trial.

GDNF rescues the fate of neural progenitor grafts by attenuating Notch signals in the injured spinal cord in rodents.

Neural progenitor cell (NPC) transplantation is a promising strategy for the treatment of spinal cord injury (SCI). In this study, we show that injury-induced Notch activation in the spinal cord microenvironment biases the fate of transplanted NPCs toward astrocytes in rodents. In a screen for potential clinically relevant factors to modulate Notch signaling, we identified glial cell-derived neurotrophic factor (GDNF).

Preference Reversals in Decision Making Under Risk are Accompanied by Changes in Attention to Different Attributes.

Recent work has shown that visual fixations reflect and influence trial-to-trial variability in people's preferences between goods. Here we extend this principle to attribute weights during decision making under risk. We measured eye movements while people chose between two risky gambles or bid on a single gamble.

Dental attrition models predicting temporomandibular joint disease or masticatory muscle pain versus asymptomatic controls.

Aims: To determine whether patients with temporomandibular joint disease or masticatory muscle pain can be usefully differentiated from asymptomatic controls using multifactorial classification tree models of attrition severity and/or rates.

Methods: Measures of attrition severity and rates in patients diagnosed with disc displacement (n = 52), osteoarthrosis (n = 74), or masticatory muscle pain only (n = 43) were compared against those in asymptomatic controls (n = 132). Cross-validated classification tree models were tested for fit with sensitivity, specificity, accuracy and log likelihood accountability.

Validation of a behavioral health treatment outcome and assessment tool designed for naturalistic settings: The Treatment Outcome Package.

In 1994, the American Psychological Association and the Society for Psychotherapy Research convened a Core Battery Conference to develop a set of criteria for the selection of a universal core battery that could be used as a common outcome tool across all outcome studies. The Treatment Outcome Package (TOP) is a behavioral health assessment and outcome battery with modules for assessing a wide array of behavioral health symptoms and functioning, demographics, case-mix, and treatment satisfaction. It was developed to follow the design specifications set forth by the Core Battery Conference, but also to ensure the battery's applicability to naturalistic treatment settings in which randomization may be impossible.

Improved interaction models of temporomandibular joint anatomic relationships in asymptomatic subjects and patients with disc displacement with or without reduction.

Aims: To consider temporomandibular joint (TMJ) anatomic interactions in order to refine hard tissue models differentiating (1) joints diagnosed with disc displacement with reduction (DDwR) or without reduction (DDw/oR) from asymptomatic joints (Normals), and (2) DDwR joints from DDw/oR joints.

Methods: TMJ tomograms of 84 women with unilateral DDwR and 78 with unilateral DDw/oR were compared against each other and against those of 42 female Normal joints through the use of 14 linear and angular measurements, 8 ratios, and 34 interactions. A classification tree model for each comparison was tested for fit with sensitivity, specificity, accuracy, and log likelihood and compared to logistic regression models.

Customized heel pads and soft orthotics to treat heel pain and plantar fasciitis.

We describe the design of a new cost-effective, comfortable orthotic designed to treat heel pain associated with plantar fasciitis. The heel pad is fabricated from a 4 degrees Sorbothane medial wedge with a customized insertion of low-density Plastazote. The orthotic is medium-density Plastazote reinforced with cork in the medial longitudinal arch.

Relationships between God and people in the Bible: a core conflictual relationship theme study of the Pentateuch/Torah.

The most widely known images of God are from the Bible. An important characteristic of these images is their portrayal of God's interactions with people. Although there have been many religious and literary discussions of God's relationships with people in the Bible, no systematic psychological assessment has been reported.

Multifactorial comparison of disk displacement with and without reduction to normals according to temporomandibular joint hard tissue anatomic relationships.

Statement Of Problem: There is disagreement about the predictive value of temporomandibular joint tomographic anatomy in the diagnosis of internal derangements.

Purpose: This study aimed to identify multifactorial temporomandibular hard tissue relationships that differentiate disk displacement with reduction and disk displacement without reduction from normals.

Material And Methods: Temporomandibular joint tomograms from females diagnosed with unilateral disk displacement with (n=84) or without (n=78) reduction were compared to 42 asymptomatic normal joints with the use of 14 linear and angular measurements and 8 ratios.

Multifactorial modeling of temporomandibular anatomic and orthopedic relationships in normal versus undifferentiated disk displacement joints.

Statement Of Problem: There is persistent dispute about the diagnostic value of hard tissue anatomic relationships in predicting temporomandibular joint disorders and normals.

Purpose: The goal of this study was identification of multifactorial temporomandibular hard tissue relationships that differentiate asymptomatic normal joints.

Material And Methods: Central section lateral tomograms of 162 female temporomandibular joints with pooled diagnoses of unilateral disk displacement with and without reduction were compared to 42 female asymptomatic normal joints using 14 linear and angular measurements and 8 ratios.

Multifactorial analysis of differences in temporomandibular joint hard tissue anatomic relationships between disk displacement with and without reduction in women.

Statement Of Problem: Without multifactorial models, it is difficult to resolve whether hard tissue tomographic relationships can distinguish differences between temporomandibular joint (TMJ) internal derangement diagnoses.

Purpose: The purpose of this study was to use multifactorial models to examine whether there are hard tissue anatomic and orthopedic characteristics that distinguish temporomandibular joints with disk displacement with reduction from disk displacement without reduction.

The relationship of depression and stressors to immunological assays: a meta-analytic review.

This is a broad meta-analysis of the relations of both depression and stressors to immunological assays. The number of study samples (greater than 180) and measures (greater than 40) is much more extensive than any so far. Analyses are done by both fixed and random effects.

The Penn Psychoanalytic Treatment Collection: a set of complete and recorded psychoanalyses as a research resource.

From a set of seventeen complete and tape-recorded psychoanalyses, a sample of findings is presented: (a) the level of agreement of two clinical judges on the psychological health of these patients is adequate for the late sessions, but not for the early sessions; (b) the amount of change during psychoanalysis appears to be similar to that in the Menninger Foundation Psychotherapy Research Project; (c) psychiatric severity measures from the early sessions can yield a significant level of prediction of the later benefits from psychoanalysis. Finally, further research uses of this collection of psychoanalyses are suggested.

Analysis of occlusal variables, dental attrition, and age for distinguishing healthy controls from female patients with intracapsular temporomandibular disorders.

Statement Of Problem: Confusion about the relationship of occlusion to temporomandibular disorders (TMD) persists.

Purpose: This study attempted to identify occlusal and attrition factors plus age that would characterize asymptomatic normal female subjects.

Methods And Material: A total of 124 female patients with intracapsular TMD were compared with 47 asymptomatic female controls for associations to 9 occlusal factors, 3 attrition severity measures, and age using classification tree, multiple stepwise logistic regression, and univariate analyses.

Quantification and validation of predictive values of occlusal variables in temporomandibular disorders using a multifactorial analysis.

Statement Of Problem: A consensus is lacking on the association between occlusal variables and temporomandibular disorders (TMDs).

Purpose: This study estimated the maximum potential power of occlusal variables to differentiate patients with TMD from asymptomatic normal adult subjects.

Material And Methods: The occlusal characteristics in 2 sets of female patients with intracapsular TMD (1993, n = 257, and 1998, n = 124) differentiated into disk displacement and osteoarthrosis subdiagnoses were compared with asymptomatic female controls (n = 51 and 47) with multiple logistic regression analysis.

A multiple stepwise logistic regression analysis of trauma history and 16 other history and dental cofactors in females with temporomandibular disorders.

The simultaneous contribution of 11 occlusal factors, dental attrition severity, orthodontic history, trauma (motor vehicle accident [MVA] and non-MVA), and age in defining two independent large populations of females diagnosed with five mutually exclusive temporomandibular disorders was tested through multiple stepwise logistic regression analysis. Non-MVA trauma was significant in both groups in defining disc displacement (DD) with and without reduction, and osteoarthrosis (OA) (both primary and following DD). Anterior open bite was also a significant factor in defining OA in both groups.

The degree to which dental attrition in modern society is a function of age and of canine contact.

Dental attrition ranked according to a validated severity scale correlated with age as a proxy for functional wear in 148 asymptomatic subjects. Anterior, posterior, mediotrusive, laterotrusive, and total attrition severity was analyzed. The geometric contribution of canine attrition to the variance of posterior attrition was also tested through correlations, and the time span required to record a statistically significant difference in attrition using the scale was determined.
