title: Benchmark for Euclidean Single-Depot Bounded Multiple Travelling Salesman Problem instances

description: This repository introduces 168 novel instances (file: instances-168.csv) designed for solving the Euclidean Single-Depot Bounded Multiple Traveling Salesman Problem (Bounded MTSP). These instances are adapted from the TSP library, with city '1' designated as the depot, and the remaining 'n-1' cities representing destinations to be visited by 'k' salesmen. To define the tour constraints, we establish 'm_{min}' (minimum) and 'm_{max}' (maximum) values, informed by real-world surveys reflecting client visits ranging from 15 to 60. Our repository provides three sets of 'm_{min}' and 'm_{max}' pairs: 30, 50; 24, 40; and 18, 30. Additionally, the value for 'k' is calculated using the formula:

 ⎡ 1.3 x n ⎤
k( n , m_{max} ) = ⎜ ⎼⎼⎼⎼⎼⎼⎼ ⎥
 ⎜ m_{max} ⎥

In addition to the 168 new instances, we have included 6 instances proposed by (Junjie & Dingwei, 2006) (file instances-6.csv) and 16 instances proposed by (Necula et al. 2015) (instances-16.csv), raising the total to 190 instances. For each instance, we provide the best solution delivered by our 3-phase algorithm (folders: solutions-22 and solutions-163) and its corresponding solution graph (folder: graphs), along with a table detailing the minimum, average and maximum costs, the run number in which the best cost was obtained and the time elapsed to obtain that best cost, as well as the average processing time, the best cost and the lower bound achieved by the CPLEX solver (IBM, 2024), as well as the elapsed processing time, limited to 2 hours (file: results.xlsx).

These instances serve as valuable benchmarks for researchers exploring MTSP variants.

title: Seasonal soil active layer measurements from a Circumpolar Active Layer monitoring (CALM) grid, R54c Gyda, West Siberia 2016-2020

description: The Circumpolar Active Layer Monitoring (CALM) program represents the only coordinated program providing collection, standardization, open access, and dissemination of active-layer data world-wide. Widespread, systematic changes in the thickness of the active layer could have profound effects on the flux of greenhouse gases, on the human infrastructure in cold regions, and on landscape and hydrologic processes. It is therefore critical that observational and analytical procedures continue over decadal periods to assess trends and detect cumulative, long-term changes. This dataset contains active-layer observations conducted by the CALM program since the 1990s, supported by a series of National Science Foundation (NSF) awards. CALM program is an integral part of the Global Terrestrial Network for Permafrost.
 CALM 2020 data are significantly reduced due to pandemic-related travel restrictions. Available 2020 data are limited in terms of extent, and observations were not as controlled as previous years in terms of measurement timing or method, and therefore should be treated with caution.

title: ENHANCING EFL LISTENING AND SPEAKING THROUGH TED TALKS AND PEER TEACHING

description: This mixed-methods study investigates the efficacy of integrating TED Talks with peer teaching to enhance EFL listening and speaking proficiency among 72 Uzbek university students (CEFR B1). Over 12 weeks, the experimental group (n=36) engaged with curated TED Talks followed by peer-led discussions and presentations, while the control group (n=36) followed traditional textbook listening/speaking instruction. Pre/post-test IELTS-style assessments revealed statistically significant gains for the experimental group (listening: +24%; speaking: +31%; p<0.001), corroborated by qualitative data indicating enhanced motivation, fluency, and confidence. Peer teaching amplified TED Talk exposure through active production, fostering incidental vocabulary acquisition (Cohen's d=1.42) and pragmatic competence. Findings demonstrate TED Talks + peer teaching as a scalable, cost-effective intervention yielding superior outcomes over conventional methods. Pedagogical implications include task design protocols, peer training frameworks, and curriculum integration strategies for resource-constrained EFL contexts.

description: This article analyzes stress resilience as an important personal determinant of psychological literacy. It is scientifically substantiated that in modern society, a person's psychological literacy is directly related to his attitude to stressful situations, emotional stability and level of adaptability. The study highlights the content of the concept of stress resilience, its relationship with psychological literacy, and its importance in personal development. Also, a comparative analysis of the scientific views of Uzbek, CIS and foreign scientists was conducted, and theoretical conclusions on the problem were developed. The results of the article indicate the need to form stress resilience in the development of psychological literacy.
