Summary: The human brain has evolved to predict and anticipate environmental events from their temporal dynamics, influencing perception and decision-making processes. Perceptual decisions are influenced by both past and future states of sensory signals, with decisional serial dependence and representational momentum playing roles in these processes. The independent binding of stimuli and decisions over time is supported by the coexistence of these two phenomena.

Summary: In humans, certain neurons in the dorsal root ganglion express receptors for pruritogens such as ALA and BAM8-22, whereas in nonhuman primates, specific C-fiber nociceptors are preferentially activated by these pruritogens. Additionally, when pruritogens are administered in combination, human volunteers report itch and nociceptive sensations similar to those induced by a single pruritogen. These findings suggest differences in pruriceptive processing between primates and rodents, and challenge the spatial contrast theory of coding of itch and pain.

Summary: This study addresses the problem of unsupervised domain adaptation under generalized target shift, showing the importance of aligning marginals and class-conditional distributions across domains for good generalization. The proposed learning framework minimizes importance weighted loss in the source domain and utilizes a Wasserstein distance between weighted marginals, with an estimator of target label proportion blending mixture estimation and optimal matching by optimal transport. Experimental results demonstrate the method outperforms competitors on various domain adaptation problems.

Summary: Recent work suggests that serial dependence arises from the prior that sensory input is temporally correlated. By manipulating the temporal statistics of visual stimuli, researchers found that temporal correlation in the stimulus history leads to repulsive biases, while temporal correlation in the decision history reduces attractive biases.

Summary: This paper presents three different models to address the distributed solar photovoltaic investment problem: net-metering status-quo, a sharing economy model, and a cooperative PV decision problem faced by an aggregator participating in wholesale electric markets. These new business models offer a plausible pathway to maintain and even accelerate PV investment.

Summary: This study investigates the mission abort policies of safety-critical mission-based systems, such as aircraft and submarines, to enhance their survivability. The mission abort decisions are considered in a two-stage degradation process, aiming to minimize the expected total cost of mission failure and system failure. The study also evaluates heuristic policies and formulates a joint optimization problem to determine the optimal mission abort policy and investment for delaying system deterioration.

Summary: Climate change poses risks to the benefits of forest-dependent communities worldwide. The use of genomics-based assisted migration may help protect these benefits, but it also generates new risks and uncertainties. Different stakeholders have different perspectives on the risks and uncertainties associated with this strategy. The health and integrity of the forest ecosystem is considered the highest priority in forest management.

Summary: This study investigates the performance limits of a millimeter-wave communication system with Nakagami-m fading channels, finding that traditional design criteria for STCs are suboptimal for this specific type of fading channel. By deriving tight upper bounds on error probabilities and investigating the effect of blockage, the research reveals fundamental trade-offs in maximizing diversity and coding gains. The findings suggest that STCs need to be redesigned for Nakagami-m fading channels to achieve full diversity.

Summary: Dynamic index coding is a practical extension of traditional index coding for handling real traffic streams. Our work focuses on identifying the code-constrained capacity region and introducing the performance metric of dynamic index coding gain. We propose a greedy scheme and a time-shared friendly scheme, with the latter achieving maximum coding gain and lower delay. We also provide a closed-form solution for the optimization problem in the two-flow case and extend the results to problems with arbitrary side information graphs. Analytical and simulation results are used to provide graphical intuition.

Summary: A statistical analysis of large neuronal avalanches in mouse and rat brain tissues reveals recurrent activity and cyclic patterns of activation, unlike smaller avalanches. By adapting a model of structural weakening in materials, it is found that dynamical weakening of neuron firing thresholds closely replicates experimental observations. This suggests that dynamical weakening plays a crucial role in the recurrent activity of large neuronal avalanches, providing insights into the causes and dynamics of conditions such as seizures.

Summary: The study finds that small business loans originated during Ramadan in Turkey are more likely to default, especially those originated during hot Ramadan and approved by busy bank branches. Despite the higher default rate, Ramadan loans have lower credit spreads.

Summary: The adult brain shows remarkable plasticity by recalibrating its perceptual estimates based on information from multiple sensory sources. In this study, single-neuron activity was recorded in monkeys' brains, revealing that early multisensory cortices participate in unsupervised recalibration, while the VIP area reflects a global shift in vestibular space.

Summary: Empirical studies have shown that many firms initially filing for Chapter 11 bankruptcy protection are eventually converted to Chapter 7 bankruptcy by judges, and the conversion rate varies among judges. This study examines the optimal financial decisions of a firm facing forced conversion. The findings indicate that forced conversion reduces shareholders' incentives to invest and decreases the optimal leverage ratio. The study also highlights the increased sensitivity of equity risk to forced conversion after filing for Chapter 11.

Summary: The effects of mood on economic choices may stem from mechanisms adapted to natural environments, biasing the expected value of actions. A study found that in positive mood, economic choices tended to favor options with higher rewards but higher costs.

Summary: A series of studies has identified different groups of neurons in the orbitofrontal cortex (OFC) that encode the value of individual options, the choice outcome, and the chosen value. Recent research showed that these neuronal responses are similar under simultaneous and sequential offers, indicating that economic choices rely on the same neural circuit regardless of presentation order.

Summary: In this study, Chiang et al. investigate the population coding of self-ordered sequences in the prefrontal cortex. They find that consistent ordering leads to better decoding, more distributed information, and less variability, which may contribute to planning and memory.

Summary: The role of the dorsal anterior cingulate cortex (ACCd) in decision making remains somewhat unclear. While it encodes post-decision variables, it does not represent pre-decision variables like the individual offer values. Thus, ongoing decisions are unlikely guided by ACCd, but its neuronal activity may inform subsequent actions.
