Study Objective: This study aims to evaluate the frequency of occurrence of cyclical behavioral changes in women with mental retardation, as well as the effectiveness of several treatment modalities for this type of behavior.
Design: Retrospective chart analysis.
Setting: University of Michigan clinic for reproductive healthcare of women with mental disabilities.
Participants: All clinic patients of reproductive age, presenting with cyclical behavioral changes in our clinic from November 1985 to October 1992.
Interventions: Medical treatment of cyclical behavioral changes.
Main Outcome Measures: Presence and documentation of cyclical behavioral changes, level of retardation, type of behavior, treatment modalities and results.
Results: Ninety-three of 522 reproductive-age patients (18%) presented with cyclical behavioral changes. Good documentation with behavior charts was present in 46% of these records. Level of retardation among the women included: 57 (61%) severely, 12 (13%) moderately, and 1 (1%) mildly retarded. No level of retardation could be detected in 23 (25%) women. Aggressive behavior was noted in 35 (38%) women, self-mutilation in 20 (22%) a combination of both in 10 (10%) and other behavior in 28 (28%) women. Primary treatment was by physician preference. Of 46 patients who received nonsteroidal antiinflammatory drugs (NSAID), 30 (65%) showed improvement, 10 (21%) showed no improvement, and 2 patients (4%) showed worsening symptoms. Birth control pills were used in 15 patients; there were signs of improvement in 6 (40%), no improvement in 3 (20%), and worsening in 3 (20%). The use of depomedroxyprogesterone injections was successful in treating 6 of 9 patients (66%), and showed no improvement in 2 women. No statistically significant differences were found between these treatment modalities.
Conclusions: Cyclical behavioral changes in women with mental retardation is a common problem (18%) and may be related to pain- possibly due to menstrual cramps, since 65% of the patients responded to NSAID. If treatment with NSAID is unsuccessful, birth control pills and depomedroxyprogesterone improved behavior in 40% to 66% of patients. Documentation is a key issue.

Beta oscillations predict the envelope sharpness in a rhythmic beat sequence.

Periodic sensory inputs entrain oscillatory brain activity, reflecting a neural mechanism that might be fundamental to temporal prediction and perception. Most environmental rhythms and patterns in human behavior, such as walking, dancing, and speech do not, however, display strict isochrony but are instead quasi-periodic. Research has shown that neural tracking of speech is driven by modulations of the amplitude envelope, especially via sharp acoustic edges, which serve as prominent temporal landmarks.

Background: Recent advances in multimodal signal analysis enable the identification of subtle drug-induced anomalies in sleep that traditional methods often miss.
New Method: We develop and introduce the Dynamic Representation of Multimodal Activity and Markov States (DREAMS) framework, which embeds explainable artificial intelligence (XAI) techniques to model hidden state transitions during sleep using tensorized EEG, EMG, and EOG signals from 22 subjects across three age groups (18-29, 30-49, and 50-66 years). By combining Tucker decomposition with probabilistic Hidden Markov Modeling, we quantified age-specific, temazepam-induced hidden states and significant differences in transition probabilities.
Growth decline in European beech associated with temperature-driven increase in reproductive allocation.

Climate change is impacting forests in complex ways, with indirect effects arising from interactions between tree growth and reproduction often overlooked. Our 43-y study of European beech () showed that rising summer temperatures since 2005 have led to more frequent seed production events. This shift increases reproductive effort but depletes the trees' stored resources due to insufficient recovery periods between seed crops.

Drought is a reoccurring natural phenomenon that presents significant challenges to agricultural production, ecosystem stability, and water resource management. The Central Highlands of Vietnam, a major region of industrial crops and vegetation ecosystems, has become increasingly vulnerable to drought impacts. Despite this vulnerability, limited research has explored the specific characteristics of drought and its seasonal effects on vegetation ecosystems in the region.
