We present the first experimental observation of (2+1) -dimensional multimode (composite) solitons. A single-hump component and a double-hump (dipole-type) component are jointly self-trapped as a composite soliton in a biased photorefractive crystal.

BACKGROUND Hump reduction in aesthetic rhinoplasty destabilizes the middle vault. Secondary maneuvers are necessary to avoid the long-term functional and aesthetic sequelae of middle vault collapse. We describe a new technique of reinserting the resected hump that combines (a) placement of the modified hump between the upper laterals and (b) bridging sutures between the upper laterals. METHOD...

Recent tests of a 250 m/m structured packing in a 1.22 m diameter column have produced some unanticipated results. Using two quite different systems, mass transfer performance in a relatively short 1.69 m bed was significantly better than previous results in a longer 3.78 m bed. No bed length effect was found on pressure drop. Two different severe vapor maldistributions were studied using a vac...

Charge movement was measured in frog cut twitch fibers with the double Vaseline gap technique. Five manipulations listed below were applied to investigate their effects on the hump component (I gamma) in the ON segments of TEST minus CONTROL current traces. When external Cl-1 was replaced by MeSO3- to eliminate Cl current, I gamma peaked earlier due to a few millivolts shift of the voltage depe...

The operative procedure frequently used to narrow the nasal pyramid in the context of a regular rhinoplasty is well known to all rhinoplastic surgeons. It consists of hump removal, followed by lateral osteotomies and medialization of the nasal bones. However, narrowing of a wide nasal pyramid, in the absence of an appreciable dorsal hump, as in the case of an ideal dorsal height or a mild hump,...

BACKGROUND Vertebral rotation found in structural scoliosis contributes to trunkal asymmetry which is commonly measured with a simple Scoliometer device on a patient's thorax in the forward flexed position. The new generation of mobile 'smartphones' have an integrated accelerometer, making accurate angle measurement possible, which provides a potentially useful clinical tool for assessing rib h...

BACKGROUND Facial lipoatrophy, a common alteration among HIV-1-infected, antiretroviral-treated patients, is often corrected using autologous transplantation. In some cases, especially when enlarged adipose tissue from the dorso-cervical area (that is, a 'buffalo hump') is used as a source of fat for transplantation, the transplanted fat develops progressive hypertrophy. To gain insight into th...

Dallas, Texas Dorsal hump reduction can create both functional and aesthetic problems if performed incorrectly. Component dorsal hump reduction allows a graduated approach to the correction of the nasal dorsum by emphasizing the integrity of the upper lateral cartilages when performing dorsal reduction. Use of this approach can minimize the need for spreader grafts in primary rhinoplasty patien...
