Summary: Studies have found that individuals with schizophrenia have increased neuronal background noise, leading to temporal imprecision in the processing of external stimuli. Analyzing electroencephalography data, it was discovered that individuals with schizophrenia had decreased signal-to-noise ratio and inter-trial phase coherence compared to healthy controls. Computational modeling demonstrated a decrease in neural synchrony in individuals with schizophrenia, which was related to behavioral temporal imprecision.

Summary: The intrinsic difference between spike timing-based and rate-based computations was examined using Tempotron and Perceptron as neural models. Spike timing-based computation showed superiority in discriminating forward vs. reverse sequence of events, which was attributed to the asymmetric profile of the postsynaptic potential (PSP) and the biased spatial distribution of synaptic weight modifications during learning.

Summary: This study investigates the temporal variability of resting-state brain networks in schizophrenia patients and reveals attenuated temporal variability among multiple electrodes in the frontal and right parietal lobes, as well as strengthened posterior and peripheral flexible connections. These temporal fluctuation distortions reflect an abnormality in the coordination of functional network switching in schizophrenia, which affects task performance and individual complexity metrics.

Summary: This study used an electronic ground conductivity meter to measure soil conductivity and conducted spatial and temporal analysis to study the impact of flood irrigation on soil salinity. The results showed that the optimal timing for cotton sowing was within 15 days after flood irrigation, which effectively reduced soil salinity.

Summary: Individuals with autism spectrum disorder (ASD) often demonstrate disordered speech prosody, particularly in timing and syllable durations. This study found significant differences in relative timing and syllable durations at phrase ends for the ASD group, as well as a correlation between variability in speech and drumming tasks, suggesting deficits in temporal processing in both speech and non-speech motor domains.

Summary: With the development of rs-fMRI technology, functional connectivity network has shown potential for identifying neuropsychiatric disorders. Traditional static functional connectivity network ignores the dynamic changes and high-order interactions. This article proposes a dynamic functional connectivity network to characterize connectivity variation across time and a high-order functional connectivity network to reflect complex interactions. Experimental results demonstrate the effectiveness of the method for schizophrenia identification.

Summary: Over the past few decades, researchers have been studying time perception and its processing in the brain. Different regions in the brain play varying roles in timing tasks, depending on factors such as duration, task type, and modality. This meta-analysis aimed to identify regions specifically activated in explicit timing tasks, using two datasets and the activation likelihood estimation algorithm. The results showed that the left supplementary motor area (SMA) and the bilateral insula were the most likely activated regions in explicit timing tasks.

Summary: The timing and operations of dam filling can lead to conflicts associated with the dam's lifetime, which can be mitigated by adaptive solutions responding to hydroclimatic fluctuations. Study findings from the Gibe III dam filling show the benefits of adaptive strategies in achieving hydropower production while minimizing negative impacts on downstream users.

Summary: This study aims to understand the relationship between positive affect (PA) and negative affect (NA) among people with schizophrenia, and explore the impact of social context on mood variability. The results show that some patients with schizophrenia do not experience negative affect, some experience both positive and negative affect, and some show a more normative affect pattern.

Summary: This study used an ultra-wide-bandwidth low-frequency (UWL) receiver installed on the 64 m Parkes Radio Telescope to observe 35 ms pulsars, and analyzed the data using wide-band timing methods. The results include a set of profile evolution models and new timing solutions, with a precision of TOA and DM measurements ranging from 0.005 to 2.08 μs and (0.043-14.24) x 10(-4) cm(-3) pc, respectively. 94% of the pulsars achieved a median TOA uncertainty of less than 1 μs.

Summary: The study suggests that listeners' beliefs about phonetic variation in speech perception play a role in informing their perception. Previous fMRI research found that the right middle temporal gyrus (RMTG) is sensitive to typical phonetic variants used by a talker. This current study used transcranial magnetic stimulation (TMS) to test if RMTG has a causal role in processing talker-specific phonetic variation. The results showed that regardless of stimulation site (RMTG, left MTG, or scalp vertex), listeners could accurately identify which variant was typical of a trained talker.

Summary: Dynamic control over molecular emission is achieved through time-encoded locking and unlocking of individual vibrational emissive units, allowing for the development of dynamic multicolor fluorescent systems. The emission wavelength and lifetime can be readily controlled by adding chemical fuels, providing a robust and versatile way to modulate multi-color molecular emission in a time-dependent manner.

Summary: In this commentary, the author summarizes their motivation to study timing in schizophrenia and their interest in non-conscious mechanisms. They highlight the contrast between the processing of numerous tiny sensory characteristics, mostly unconsciously, and the subjective experience of stability and continuity. The author's work suggests that this is also true for timing, and their studies have revealed mechanisms that help us ignore the disruptive signals that can affect our sense of time continuity. They propose that further research on timing could help connect neurobiology, cognition, and clinical disorders in individuals with schizophrenia, ultimately contributing to the development of innovative therapeutics.

Summary: Comparison of lower-extremity intra-joint coordination and its variability between fallers and non-fallers older adults during gait showed significant differences in spatiotemporal gait parameters and joint coordination patterns. Fallers exhibited lower cadence, walking speed, and stride length but greater double support and stride time than non-fallers. Differences in segment coordination and its variability suggest potential adaptations resulting from decreased efficiency and inconsistencies in neuromuscular control, indicating reduced ability to generate power during the push-off phase in fallers.

Summary: While the microfilarial density of L.loa is stable at the community level, significant variations have been observed at the individual level. These variations may have an important impact on the control of onchocerciasis and the evaluation of interventions on L.loa microfilaraemia.
