purpose: to compare the anatomical results of scleral buckling surgery with and without retinopexy in the management of phakic rhegmatogenous retinal detachment (rd). methods: in this retrospective, nonrandomized, interventional, comparative case series, data of 71 phakic eyes of 71 patients with rhegmatogenous rd that had undergone scleral buckling were evaluated. the procedure in 41 consecuti...

the purpose of this study was to compare the anatomic and visual outcome of primary vitrectomy with scleral buckling in patients with retinal detachment following cataract surgery. fifty-six consecutive patients with retinal detachment after cataract surgery were randomly assigned to two treatment groups: standard scleral buckling and standard three-port deep vitrectomy. successful treatment wa...

We report photoelectron spectroscopy (PES) and high-resolution PE imaging of AuC2(-) at a wide range of photon energies. The ground state of AuC2(-) is found to be linear (C∞v, (1)Σ(+)) with a …8π(4)4δ(4)17σ(2)9π(4)18σ(2) valence configuration. Detachments from all the five valence orbitals of the ground state of AuC2(-) are observed at 193 nm. High-resolution PE images are obtained in the ener...

Laser photodissociation spectroscopy of the I-·thymine (I-·T) and I-·cytosine (I-·C) nucleobase clusters has been conducted for the first time across the regions above the electron detachment thresholds to explore the excited states and photodissociation channels. Although photodepletion is strong, only weak ionic photofragment signals are observed, indicating that the clusters decay predominan...

A machine learning approach has been implemented to measure the electron temperature directly from emission spectra of a tokamak plasma. This utilized neural network (NN) trained on dataset 1865 time slices operation DIII-D using extreme ultraviolet/vacuum ultraviolet spectroscopy matched with high-accuracy divertor Thomson scattering measurements temperature, Te. NN is shown be particularly go...

The composite fermion (CF) model of the quantum Hall effect which gives the correct series of charges is based on attachment of flux quanta to the electron. The construction of the series of charges leads to a field expression which requires that flux quanta are attached to the electron. The series based on the experimental data is correct but the field deduced from such a series is found to be...
