Summary: We analyzed SARS-CoV-2 genome copies in Catalonia's wastewater and developed a mathematical model to estimate the number of infections and the temporal relationship between reported and unreported cases. Samples from 16 wastewater treatment plants were used in an epidemiological model, showing a strong correlation between genome copies and reported cases with a delay of 8.8 days. The model estimated a higher infection rate (53%) compared to the reported cases (19%), indicating under-reporting in November and December 2021. The maximum genome copies shed in feces by an infected individual ranged from 1.4 x 108 gc/g to 4.4 x 108 gc/g. This study highlights the potential of using wastewater data as an early indicator for new infections and provides a framework for integrating such data into epidemiological models.

Summary: This study utilized 7T fMRI and biologically-inspired analyses to uncover a network of neural populations tuned to both small and large numerosities, organized within the same topographic maps. The results demonstrate a continuum of numerosity preferences that progressively cover both the subitizing range and beyond within the same numerosity map, suggesting a single neural mechanism. The authors hypothesize that differences in map properties, such as cortical magnification and tuning width, underlie known differences in behavior.

Summary: We demonstrate the applicability of quantum detector tomography to study human perception of photon number states in the visual system. By recording the response of a detector to light pulses with known photon statistics of varying intensity, a model can be fitted to infer the detector's photon number state response. Our study shows that detector tomography is feasible for human experiments, opening up opportunities to explore human perception on the quantum level.

Summary: This study reveals that the nervous system does not universally compensate for the effects of gravity during translation, with the colinear effect of gravity significantly decreasing sensitivity to certain motions. Body orientation has an overall impact on perception, potentially reflecting the influence of gravity on self-motion perception.

Summary: In this paper, the gamma asymmetric kernel for boundary correction and threshold function eliminating jump impacts are combined to estimate the unknown drift coefficient in the jump diffusion process of interest rate. The asymptotic large sample property and the better finite sample property of the corresponding estimator are considered through Monte Carlo numerical simulation experiment and empirical analysis of SHIBOR and LIBOR. The estimator proposed in this paper can correct the estimation error near or far away from the origin point, providing a more asymptotic unbiased estimator for the drift function in diffusion models with jumps.

Summary: Decisions are influenced by the accumulation of decision-relevant information over time, with early and late evidence often given stronger weight. Intermittent choices reduce sensitivity to subsequent decision information and transiently boost arousal, potentially triggering a state change in decision-making neural circuits.

Summary: By studying the perceptual thresholds of patients and healthy individuals, scientists have found that vestibular function plays an important role in the perception of rotation and tilt. Patients without vestibular function have higher thresholds for tilt and rotation, while other sensory cues such as touch play a more significant role in tilt perception. Additionally, stimulus frequency affects perception.

Summary: For over a century, psychophysics has been used in various scientific and healthcare fields to objectively measure sensory phenomena. This manuscript provides an overview of fundamental concepts in psychophysics, with a focus on pain and research applications. Psychophysics allows nursing scientists to explore subjective phenomena like pain perception with systematic and objective measures, although standardization of terms and techniques needs improvement. The interdisciplinary nature of psychophysics provides a unique perspective, similar to nursing, on how measurable sensations influence our perceptions. Nursing science has the opportunity to contribute to pain research by utilizing psychophysical procedures.

Summary: Simultanagnosia is a deficit in processing multiple visual elements simultaneously due to bilateral posterior parietal damage. Research found that patients with focal and bilateral SPL lesions performed slower in visual search tasks involving separable lines. When surrounded by distracters, the patient's ability to identify objects dropped, but improved when given specific search instructions.

Summary: This study investigated temporal crowding, the impaired object identification when distracting objects precede and succeed the target. The study found clear evidence of temporal crowding in central vision, with reduced encoding precision as a unique characteristic. The magnitude of temporal crowding was similar in central and peripheral vision, indicating the involvement of higher visual areas. The impairment of precision emerged even when only the target contained orientation information, underscoring the importance of orientation-selective mechanisms.

Summary: Visual stimuli presented around the time of a saccade can be perceived differently by the visual system, including a reduction in the harmful impact of flankers. This study investigated the effects of microsaccades on crowded stimuli placed 20 arc minutes from the center of gaze. The findings suggest two separate pre-saccadic benefits, one that regularizes the crowding zone and another that specifically benefits microsaccade targets surrounded by tangential flankers.

Summary: This study revealed that less than one-third of adults with normal binocular vision were able to successfully free-fuse random-dot image pairs and identify the embedded stereoscopic shapes. The successful participants showed a dissociation of vergence and accommodative responses, while the unsuccessful ones either exhibited strong vergence and accommodation or weak vergence and strong accommodation. Task performance of the unsuccessful cluster improved significantly with pharmacological paralysis of accommodation. A minority of participants also learned to dissociate one direction of their vergence and accommodation crosslinks with repeated free-fusion trials, optimizing their task performance.
