Other tumors include vascular tumors (e.g. hemangiomas, lymphangioma), lacrimal gland tumors (e.g. dacryoadenitis, benign mixed tumor, sarcoidosis and adenoid cystic carcinoma), and growths that extend from the sinuses into the orbit (e.g. squamous carcinoma, mucocele). Metastatic cancer can also form an orbital tumor. Lastly, an orbit tumor can also be caused by inflammation (e.g. pseudotumor,...

We report on the storage of orbital angular momenta (OAM) of light via the phenomenon of coherent population oscillation (CPO) in cold cesium atoms. The experiment is performed using a delayed four wave mixing configuration, where the transverse optical information of a probe field carrying OAM associated with its azimuthal phase dependence is stored in the CPO of Zeeman sublevels of the hyperf...

We give an analytical formulation for the approximation of the Minimum Orbital Intersection Distance (MOID) between two elliptical orbits, and we apply it to the case of the Earth and of an asteroid. With this formulation we are able to find an algorithm to compute the variance of the MOID for a given asteroid and we make the computation in the case of the asteroids whose orbit has been determi...

We report feedback-assisted adaptive multicasting from a single Gaussian mode to multiple orbital angular momentum (OAM) modes using a single phase-only spatial light modulator loaded with a complex phase pattern. By designing and optimizing the complex phase pattern through the adaptive correction of feedback coefficients, the power of each multicast OAM channel can be arbitrarily controlled. ...

The local correlation "cluster-in-molecule" (CIM) method is combined with the fragment molecular orbital (FMO) method, providing a flexible, massively parallel, and near-linear scaling approach to the calculation of electron correlation energies for large molecular systems. Although the computational scaling of the CIM algorithm is already formally linear, previous knowledge of the Hartree-Fock...

Bilateral cavernous sinus and optic nerve metastases is extremely rare. We report an extremely rare case of metastatic adenocarcinoma of bilateral cavernous sinus and optic nerve with unknown primary presenting as orbital pseudotumor. She underwent bilateral optic nerve decompression and the diagnosis was established by biopsy.

A 35-year-old woman presented with progressive left side proptosis, ophthalmoplegia and trigeminal neuralgia for one month. Brain MRI showed thickening of tentorium dura mater as typical pachymeningitis but extending to retroand intra-orbital space (figure). CSF study revealed lymphocyte predominant pleocytosis and positive PCR of mycobacterium tuberculosis. We used four combined anti-tuberculo...

The recently reported photoswitching of diarylethene derivative molecules bridging carbon nanotube (CNT) contacts is theoretically analyzed. The short lifetime of the lowest unoccupied molecular orbital (LUMO) indicates that neither the open nor closed form of the molecule can be photoexcited into a charge-neutral excited state for any appreciable length of time preventing photochromic ring ope...

Three cases of embryonal orbital rhabdomyosarcoma are presented in which two cases had intracranial extension. All three are alive and well on follow-up several years after completing a 12-month course of combined pulsed chemotherapy and irradiation. The improved prognosis even in parameningeal involvement is emphasised.

Porphyrins are widely used as dye molecules in solar cells. Knowing the energies of their frontier orbitals is crucial for optimizing the energy level structure of solar cells. We use near edge x-ray absorption fine structure (NEXAFS) spectroscopy to obtain the energy of the lowest unoccupied molecular orbital (LUMO) with respect to the N(1s) core level of the molecule. A systematic energy shif...
