Effective approach for taking into account interactions of quasiparticles from the low-temperature behavior of a deformed fermion-gas model

A deformed fermion gas model aimed at taking into account thermal and electronic properties of quasiparticle systems is devised. The model is constructed by the fermionic Fibonacci oscillators whose spectrum is given by a generalized Fibonacci sequence. We first introduce some new properties concerning the Fibonacci calculus. We then investigate the low-temperature thermostatistical properties of the model, and derive many of the deformed thermostatistical functions such as the chemical potential and the entropy in terms of the model deformation parameters p and q. We specifically focus on the p,q-deformed Sommerfeld parameter for the heat capacity of the model, and its behavior is compared with those of both the free-electron Fermi theory and the experimental data for some materials. The results obtained in this study reveal that the present deformed fermion model leads to an effective approach accounting for interaction and compositeness of quasiparticles, which have remarkable implications in many technological applications such as in nanomaterials.Comment: 33 pages, 6 figures, 1 tabl

A comparative study on q-deformed fermion oscillators

In this paper, the algebras, representations, and thermostatistics of four types of fermionic q-oscillator models, called fermionic Newton (FN), Chaichian-Kulish-Ng (CKN), Parthasarathy-Viswanathan-Chaichian (PVC), Viswanathan-Parthasarathy-Jagannathan-Chaichian (VPJC), are discussed. Similarities and differences among the properties of these models are revealed. Particular emphasis is given to the VPJC-oscillators model so that its Fock space representation is analyzed in detail. Possible physical applications of these models are concisely pointed out.Comment: 32 pages, 2 figures, to appear in Int. J. Theor. Phys. (IJTP

Comparison of antivenom effects between pediatric and adult patients presented to emergency department with scorpion stings

The aim of this study was to compare the use of antivenom, and admission to ICU, scorpinism between adult and pediatric patients. This study included 99 patients who were admitted to the emergency department with scorpion sting within 1 year. Patients demographics including age and gender, and clinical findings such as ionized Ca values, body region of sting contact and complications were recorded from the patient files and hospital records. In addition, regarding management of patients with scorpionism the use of antivenoms, admission to intensive care unit and complications developed by the patients were also recorded. Patients were divided into two groups according to age as the pediatric group including patients aged ≤ 18 years (Group 1) old and the adult group consisting of patients aged> 18 years old (Group 2). Antivenom administration was performed in 12 patients (12.2%). Antivenom was administered in 38% (n=8) of the patients in Group 1 and 5.13% (n=4) of the patients in Group 2. The mean age of patients who received antivenom was statistically significantly lower than the patients who did not receive antivenom (p [Med-Science 2020; 9(1.000): 109-13

Factors affecting seizure recurrence in the emergency department

Background: Information on Emergency Department (ED) follow-up of patients presenting with epileptic seizures is limited. Objectives: It was planned to investigate the factors affecting the recurrence of epileptic seizures in the follow-up of patients presenting to the ED with the complaint of epileptic seizures. Materials and methods: This prospective, observational, single-center study was carried out in an adult population presenting to the ED. The study included patients older than 18 years of age presenting to the ED with the complaint of epileptic seizures. Results: Of the 205 patients included in the study, 68 (33.2%) had seizure recurrence during the 6 h. In the univariable analysis, advanced age, prolonged post-ictal duration, increased seizure duration, generalized tonic clonic seizure, alcohol consumption within past 24 h, hypertension, coronary artery disease, Alzheimer's disease, prior ischemic cerebrovascular disease, low Glascow Coma Scale (GCS), high glucose, high C-Reactive Protein, high phosphorus, low potassium, high blood urea nitrogen, high lactate, increased anion gap, high osmolarity were statistically significant in predicting recurrent seizure recurrence within 6 h. According to the logistic regression, postictal duration, GCS score, and age were independent predictors in our model. The cut-off value of postictal duration in predicting seizure recurrence at the highest sensitivity (66.2%) and specificity (89.8%) was 22.5 min. Conclusion: A prolonged postictal state, low GCS score, advanced age may be an indication of seizure recurrence. Therefore, patients with a long postictal duration, low GCS score, advanced age should be followed up more carefully in terms of recurrent seizures in the ED
