A method to authenticate a server to a client is provided, including in-band and out-of-band techniques. At least a first shared secret identifies a server path, including a plurality of pre-defined locations on a frame of reference (e.g. a grid). An authentication session is initiated upon receiving a client identifier at the server-side resources. A current session instance of the grid is presented to the client, populated with characters. The process includes sharing between the client and the server a challenge identifying a random subset of the plurality of predefined locations in the server path, and a response including characters that match the characters in the locations on the server path identified by the challenge. As a result, client is capable of verifying that the server has access to the first shared secret. Then a protocol is executed to authenticate the client to the server.

The hearing system (1) is adapted to establishing a communication network (10) between devices (11, 12, 13, 14) of said hearing system (1). It is characterized by a main channel of said communication network (10), which uses at least a portion of the transmission capacity of said communication network, and which is shared between said devices. Said sharing is managed jointly by said devices using a control channel. There is no centralized decision, but a distributed decision. Preferably, said main channel and said control channel are time-multiplexed.

Compositions of matter comprising a substituted cyclodextrin and cytotoxic compound, especially cytotoxic drugs such as antibiotic, anti-fungal and anti-neoplastic, drugs are claimed. The compositions cause significantly less ulceration compared to the same formulation of cytotoxic compound without cyclodextrin compound when extravasated. The compositions may also cause less vascular irritation compared to the same formulation of cytotoxic compound without cyclodextrin when administered intravenously without extravasation. Compositions of matter comprising watersoluble cytotoxic agents, especially anticancer drugs and anti-ulceration effective or anti-irritatioin effective amounts of cyclodextrin compounds are also claimed. Methods for reducing the likelihood of ulceration and or irritation when administering the compositions according to the invention are also disclosed and claimed.

The invention discloses an SCS (structure cabling system) encased structure based on PBL (planetary boundary layer) stiffening ribs. The SCS encased structure comprises an outer steel tube, an inner steel tube, a plurality of PBL stiffening ribs arranged between the outer steel tube and the inner steel tube, and a concrete structure which is poured and molded by concrete filled inside a cavity between the outer steel tube and the inner steel tube, wherein the outer steel tube, the inner steel tube and the plurality of PBL stiffening ribs are equal in longitudinal length; the plurality of PBL stiffening ribs are arranged along the peripheral direction of the inner steel tube; the inner lateral wall of each PBL stiffening rib and the inner lateral wall of the inner steel tube are fastened and connected into a whole, and the outer lateral wall and the outer lateral wall of the outer steel tube are fastened and connected into a whole. The SCS encased structure is simple in structure, reasonable in design, convenient to construct, low in construction cost, excellent in mechanical property, and good in using effect, and the problems of large dead load of the existing encased structure, poor connection performance of the outer steel tube and the internal concrete, and small hoop effect of the outer steel tube on the internal concrete can be effectively solved.

The invention provides a rapid roadway construction method for soft and broken surrounding rocks of a deep coal mine and a support system. The rapid roadway construction method for the soft and broken surrounding rocks of the deep coal mine includes the steps that a concrete leveling layer is sprayed to the roadway surrounding rocks in a wet mode; a plurality of grid arches are tightly attached to the concrete leveling layer at preset intervals; mounting anchor rods are arranged on the grid arches in a drilling mode; the grid arches are connected through longitudinal linkage ribs; a first layer of reinforcing mesh and a second layer of reinforcing mesh are laid along a roadway, wherein the first layer of reinforcing mesh is bound with the inner side main ribs, close to the surrounding rocks, of the grid arches, and the second layer of reinforcing mesh is bound with the outer side main ribs, away from the surrounding rocks, of the grid arches; concrete is sprayed again for filling of gaps among the grid arches, the two layers of reinforcing meshes and the surrounding rocks; a concrete layer is sprayed again to completely cover the grid arches; prestress grouting anchor cables are manufactured on the grid arches to support the surrounding rocks. By the method, the soft and broken surrounding rocks can be rapidly and effectively supported, and material waste and adverse impact on the environment are reduced to the maximum extent in the construction process.

The invention discloses a CDMA soft handover method which can be used in present code division multiple access systems. The invention preserves current soft handover mechanisms triggered by a pilot signal strength variation measured by a mobile station. At the same time it introduces a communication quality indication parameter—continuous error frame indication measured by mobile station. Both function together to launch and to activate system soft handover. Without changing present soft handover processes, soft handover performance is improved, possibility of lost conversation is decreased and communication quality is raised.
