Summary: VPS35 plays a crucial role in tau metabolism and neuropathology, with its overexpression reducing pathological tau in neuronal cells while genetic silencing leads to accumulation. The availability of active cathepsin D mediates the effect of VPS35 on pathological tau accumulation, making it a potential therapeutic target for human tauopathies.

Summary: This study presents a statistical field theory for networks of integrate-and-fire neurons with stochastic spike emission, revealing the impact of spike-driven reset of the membrane voltage on population activity. The study uncovers bistability and fluctuation effects in the mean-field dynamics, as well as the roles of spike resets and recurrent inhibition in stabilizing network activity. It also calculates the phase diagram for inhibitory stabilization and finds that wide regions of parameter space exhibit inhibition-stabilized regime.

Summary: In ocean dynamics, two different treatments are found for horizontal pressure gradient force and gravity, with vertical component being much larger than horizontal in both cases. Horizontal pressure gradient force is considered dominant, while horizontal gravity is completely omitted in oceanography. The importance of horizontal gravity is identified using a non-dimensional C number, with global data showing an unexpectedly large C number around 24.

Summary: Spoken Language Identification (SLID) is a well-researched field and an important first step in multilingual speech recognition systems. This study proposes a model for Indian and foreign language recognition, which enhances data to make it robust against everyday life noise and selects relevant features through feature extraction and selection algorithms. The model achieves high accuracy on three standard datasets, indicating that these features capture language specific characteristics of speech and can be used as standard features for SLID task.

Summary: The goal of this work is two-fold: (i) to theoretically develop optimality conditions for a variational problem with interval uncertainty, and (ii) to apply the established results in a production inventory model with interval uncertainty. The necessary and sufficient optimality conditions for the interval-valued variational problem (IVVP) are proposed using interval order relations. A production inventory model is formulated considering interval-valued time-dependent production and demand rates. The optimal policy of the proposed model is studied using the established optimality conditions.

The effects of joule heating in an inclined stretching cylinder and double stratification on Jeffrey Nanofluid are analyzed. By utilizing approximation transformation and numerical techniques, the skin friction, Nusselt number, and Sherwood number are calculated and analyzed. The results show that various parameters, such as M, gamma, alpha, Deborah number, magnetic factor, Brownian motion, have different effects on the velocity, temperature, and concentration.

Summary: Financial leasing contracts often have clauses for early termination in case of lessee default. The lessor may delay terminating the contract to take advantage of increased fees due to default interest. This study aims to determine the optimal time for contract rescission when the default interest rate exceeds the contract's outstanding interest rate and the alternative investment return is deterministic. It provides a detailed list of cases in which termination is appropriate. The problem is formulated under deterministic and semi-deterministic dynamics for the opportunity cost.

Summary: We studied a simple motion differential game involving two pursuers and one evader in a two-dimensional space. The control functions of the players are restricted by Gronwall-type constraints. The objective of the pursuers is to complete the game as quickly as possible, while the evader aims to avoid capture or delay the capture time. We derived an equation for the optimal pursuit time and determined the optimal strategies for all players.
