Background: Cluster headache (CH) is a recurrent disease, characterized by severe intensity periorbital headache associated with ipsilateral autonomic signs and symptoms; attacks may occur several times per day, for periods of weeks (so-called cluster), with a relapsing periodic pattern during the year. COVID-19 pandemic has induced many lifestyle changes on the general population, especially related to the so-called lockdown. Aim of this study was to assess the clinical evolution of cluster hea...

As an important cash crop in China, Jerusalem archoke is widely used in ecological protection, vegetable development, industrial and animal husbandry production and other directions, and has important production value. However, with the rapid development of industry and agriculture in China, a large number of acid pollution gas emissions, the excessive application of agricultural fertilizers and the unreasonable farming activities of human beings, the problem of soil acidification becomes increa...

The problem of agricultural production in the face of climate fluctuations in the Municipality of Santchou over the last few decades, is acutely posed. This work focuses on the impacts of climate disturbances on agriculture in the Municipality of Santchou in western Cameroon. A total of 309 randomly sampled households were surveyed using a questionnaire and 17 community leaders were interviewed. Crop growth and agricultural systems were observed and described directly on the field. Crop yields d...

This paper is devoted to the normalized solutions of a planer L²-critical Schrödinger-Poisson system with an external potential V(x) =❘X❘²   and in-homogeneous attractive interactions K(x)∈(0,1). Applying the constraint variational method, we prove that the normalized solutions exist if and only if the interaction strength a satisfies a∈(0,a^*):=∥Q∥²_L²...

Clustering is an unsupervised machine learning technique used to organize unlabeled data into groups based on similarity. This paper applies the K-means and Fuzzy C-means clustering algorithms to a vehicle crash dataset in order to explore various patterns in the data. K-means assigns data points to clusters based on the similarity between the data point and the cluster centroids, which results in partitioning the data into distinct clusters. On the other hand, fuzzy C-means clustering allows da...

The Cognitive Resonance Theory (CRT) offers a novel theoretical framework for examining the complex interactions between algorithmic personalization, emotional engagement, and the formation of echo chambers within digital media environments. The primary aim of this study is to conceptualize and position CRT as a comprehensive framework for understanding how algorithmic personalization and emotional engagement contribute to echo chambers and societal polarization. This study employs a theoretical...

Progressive ischemic stroke (PIS) is a severe neurological condition with high disability and mortality rates, significantly increasing the economic burden on patients and healthcare systems. It also exacerbates doctor-patient tensions, potentially leading to medical disputes. This retrospective study analyzed 210 cases from the Advanced Stroke Center of the Second Affiliated Hospital of Qiqihar Medical University, comparing PIS patients with general ischemic stroke patients. The results showed ...

In this article, our focus lies on a Schrödinger equation incorporating a Hardy term. To identify the global minimizers of the functional I under a mass constraint, we utilize the Hardy inequality. In addition, we reveal that every energy ground state is directly linked to the least action solution of the associated action functional. This finding affirmatively addresses the question of whether, under broad assumptions, The functional&...
