Plasma screening effects on the energies of hydrogen atom under the influence of velocity-dependent potential

In order to examine the plasma screening and velocity-dependent potential effects on the hydrogen atom, the Schr€odinger equation including a more general exponential cosine screened Coulomb and velocity-dependent potential is solved numerically in the framework asymptotic iteration method. The more general exponential cosine screened Coulomb potential is used to model Debye and quantum plasma for the specific values of the parameters in its structure. However, in order to examine effects of velocity-dependent potential on energy values of hydrogen atom in Debye and quantum plasma, the isotropic form factor of velocity-dependent potential is given as harmonic oscillator type, q?r? ¼ qor2. Then, the energies of s and p states are calculated numerically without any approximation. In order to investigate thoroughly plasma screening effects and contribution of velocitydependent potential on energy values of hydrogen atom, the corresponding calculations are carried out by using different values of parameters of more general exponential cosine screened Coulomb potential and isotropic dependence, results of which are discusse

Hepatic encephalopathy and atypical cortical involvement in cranial MRI: Case report

Hepatik ensefalopati karaciğer fonksiyon bozukluğuna bağlı olarak hastalarda nöropsikiyatrik belirtilerin gelişimi ile karakterizedir. Siroz, portal hipertansiyon veya porto-sistemik şantlar ve akut karaciğer yetmezliği durumlarında gelişebilir. Hafif mental durum bozukluklarından derin komaya kadar değişen geniş bir klinik tablo ile ortaya çıkabilir. Manyetik rezonans görüntüleme (MRG) başta olmak üzere nöro-görüntüleme teknikleri hepatik ensefalopati tanısında kullanılabilir. Sağlıklı bireylerde kolayca metabolize edilebilen maddelerin birikimine bağlı olarak özellikle T1 ağırlıklı MRG'de iki yanlı globus pallidus yapılarında sinyal artışı izlenir. Hepatik ensefalopatide kortikal tutulum oldukça nadir bildirilmiştir. Bu yazıda kortikal ve subkortikal yapıların tutulumu ile seyreden bir hepatik ensefalopati olgusu sunulmuştur.Hepatic encephalopathy is characterized by neuropsychiatric abnormalities occurring in patients with liver dysfunction. It most commonly occurs in association with cirrhosis, portal hypertension, portal-systemic shunts and acute liver failure. Clinical features of hepatic encephalopathy varies between mild cognitive impairment to deep coma. Several neuroimaging techniques, especially magnetic resonance imaging (MRI), may eventually be useful for the diagnosis of hepatic encephalopathy. Cranial MRI may demonstrate high signal intensity in the bilateral globus pallidum on T1-weighted images. Cortical involvement due to hepatic encephalopathy is rarely reported in the literature. We presented here a case of hepatic encephalopathy with cortical and subcortical involvement

Polatuzumab vedotin, rituximab, and bendamustine combination in relapsed or refractory diffuse large B-cell lymphoma: A real-world data from Turkey

Polatuzumab vedotin (Pola) with bendamustine and rituximab (BR) is a promising option for patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). We analyzed the data of 71 R/R DLBCL patients who had been treated with Pola-BR in the named patient program from March 2018 to April 2021 from 32 centers in Turkey. All patients received up to six cycles of Pola 1.8 mg/kg, rituximab 375 mg/m2 on day 1, and bendamustine 90 mg/m2 on days 1–2 of each cycle. Median age at Pola-BR initiation was 55 (19–84). The overall response rate was 47.9%, including 32.4% CR rate when a median of 3 cycles was applied. With a median follow-up of 5 months, the median OS was 5 months. Grade 3–4 neutropenia and thrombocytopenia were the most common hematological toxicities. The real-world data from our cohort showed the Pola-BR is an effective option with a manageable toxicity profile

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Effects of laser radiation field on energies of hydrogen atom in plasmas

WOS:000362571800082In this study, for the first time, the Schrodinger equation with more general exponential cosine screened Coulomb (MGECSC) potential is solved numerically in the presence of laser radiation field within the Ehlotzky approximation using the asymptotic iteration method. The MGECSC potential includes four different potential forms in consideration of different sets of the parameters in the potential. By applying laser field, the total interaction potential of hydrogen atom embedded in plasmas converts to double well-type potential. The plasma screening effects under the influence of laser field as well as confinement effects of laser field on hydrogen atom in Debye and quantum plasmas are investigated by solving the Schrodinger equation with the laser-dressed MGECSC potential. It is resulted that since applying a monochromatic laser field on hydrogen atom embedded in a Debye and quantum plasma causes to shift in the profile of the total interaction potential, the confinement effects of laser field on hydrogen atom in plasmas modeled by the MGECSC potential change localizations of energy states.

Ladder operators and coherent states for electrons under double parabolic confinement in a quantum wire

In this study, we have chosen the spatial confinement parabolic on semiconductor quantum wire with applied magnetic field. Thus, electrons are confined in zone where two parabola overlapped by using single step between two parabolic potential. The energy eigenvalues and wave functions of electrons under this double parabolic confinement are obtained by solving Schrödinger equation in the framework of asymptotic iteration method. The creation and annihilation operators for the radial wave functions are constructed by using factorization method, it is shown that these ladder operators satisfy the commutation relations for the SU(1,1) group. Closed analytical expressions for the matrix elements of 2and / are obtained and the coherent state analysis for the system are carried out

Optical specifications of laser-induced Rosen-Morse quantum well

WOS:000470938600035In this study, for the first time, the influences of a monochromatic linearly polarized laser field on the total refractive index changes (TRICs) and the total absorption coefficients (TACs) of quantum well (QW) with the Rosen-Morse potential confinement by constituting GaAs/GaAlAs heterostructure are considered. Time-dependent in the Schrodinger equation is modified through the Kramers-Henneberger (KH) transformation and the dipole approximation, and then the laser-dressed counterpart of well potential is generated by using the Ehlotzky approximation. The bound state energy values and the wave functions of the Rosen-Morse quantum well (RMQW) under the influence of the intense laser field (ILF) are obtained by using the diagonalization method in the framework of the effective mass approach and the parabolic band approximation. The effects of structure parameters on TRICs and TACs of RMQW are also explained in detail, as well as the ILF's ones. In addition to these, the alternativeness to each other of the structure parameters and the ILF on the optical specifications is also discussed. The results of the present work are necessary and crucial in optimization of the optical specifications of RMQW to be fabricated for devices applications
