The vehicle routing problem is one of the most often studied optimization problems. In this study, an improved artificial bee colony (ABC) algorithm is proposed which is structured specifically to address the capacitated vehicle routing problem (CVRP), a significant challenge in combinatorial optimization. The proposed algorithm integrates several novel features to improve its performance on CVRP

Electrification of regional railway systems constitutes a promising strategy for reducing greenhouse gas (GHG) emissions and improving air quality in the transportation sector. While full electrification via overhead line equipment (OLE) is technically viable for high-density corridors, it is often not economically justified on low-traffic routes due to high infrastructure costs relative to usage

Efficient energy management is a key challenge for regional train services,especially when considering the seasonal variation in auxiliary energy demands such as heating, ventilation, and air conditioning (HVAC). This studyexplores how adjusting the maximum operational speed of regional trains canoptimize energy consumption without exceeding design limits or necessitating larger battery sizes. By

BACKGROUND AND PURPOSE: Interphalangeal joint arthrodesis of the hand is a common procedure, but data on outcomes and complications is limited. We aimed to determine the non-union rate, evaluate risk factors for non-union, and investigate the frequency and distribution of complications across different fixation methods.METHODS: We retrospectively reviewed all interphalangeal joint arthrodeses perf

Background The assessment of pituitary tumor (PT) volume is important in the treatment and follow-up of patients with PT. Previously, PT volume estimation has been performed by conventional geometric equations (CGE) such as abc/2 (simplified ellipsoid volume equation) and 4πr 3 /3 (sphere), both presuming a symmetric tumor shape, which occurs uncommonly in patients with PT. In contrast, three-dim

Donald Trump did not invent government by insult. The ancient world had a name for it: vituperatio, the art of public blame, taught as a school exercise for centuries.In this episode I set Trump beside two of the tradition’s most consequential blamers, Jesus and the apostle Paul, and ask what has actually changed. The form turns out to be remarkably constant. What is new is the megaphone, and the

Every new student of rhetoric is nagged by the same question: what is this subject? Some finish the course still wondering.This episode does not answer with a definition. It answers with a map – eight dimensions of one and the same thing, depending on where you stand. Practice, and practice written down. Theory, and skill. The artefacts rhetoric leaves behind, a toolbox of methods, a university di

The question underneath the Zelensky deepfake is not how to spot it, but where the feeling of truth comes from in the first place. The Greeks had a word for what it is made of – eikos, the plausible, what holds for the most part – and the same faculty is at work in a courtroom in ancient Athens and in a recommendation engine. What has changed is who does the making. Plausibility has become an indu

In the recent few years, covert supply chain prevention (CSCP) in the maritime logistics is gaining lot of importance. It refers to hidden and clandestine movement of goods and services using water ways. Therefore, the presented research aims to design multidimensional approaches to assess anticipated risks and develop risk mitigation strategies comprising of technological innovations, regulatory

INTRODUCTION: Hyperbaric oxygen therapy (HBOT) is widely used as treatment of decompression sickness (DCS). The patient breathes oxygen at an elevated oxygen partial pressure of up to 280 kPa, whereas any inside attendant (IA) normally breathes air. This results in nitrogen uptake and tissue loading in the IA, which must be considered during decompression. The US Navy Treatment Table 6, and its eq

Background: The prevalence of contact allergy to linalool hydroperoxides (HPs) and limonene HPs is high and differs in different populations. Patch test techniques might affect the results. Objectives: To report the prevalence of contact allergy when the HPs were tested in different test chambers. Materials and Methods: Consecutive adult dermatitis patients were patch tested during April 2023–July

Uzbekistan’s post-2016 foreign and domestic policy trajectory offers a revealing case of how states facing acute geopolitical precarity convert vulnerability into strategic agency. Following Russia’s invasion of Ukraine and amid China’s expanding institutional and economic presence in Central Asia, Uzbekistan has been exposed to growing external pressure that might ordinarily lead to authoritarian

Enhancing the efficiency of mobility in tourism destinations is essential for their transition toward sustainability, as it reduces environmental impacts, improves visitor experiences, and strengthens local economies. The type of reconfiguration possible to achieve more efficient mobility, and how it can be accomplished, is highly dependent on the spatial embeddedness of each destination. This cha
