Abstract: FIELD: computer equipment. 
     SUBSTANCE: technical result is achieved due to the separation of the first and second analyzed texts into numbered fragments, for each of which based on known formulas numerical values of five psycholinguistic parameters are calculated. Based on the calculated values of the parameters of the first and second texts, the first and second sets of the numbered values of the common factor are calculated using the factor analysis method, respectively. Using the first and second calculated sets of numbered values of the common factor, the first and second sequences of values are created, each of which is a module of difference between adjacent numerical elements of the corresponding set of values of the common factor. First and second sets of equal numbers are selected in the first and second created numerical sequences, wherein the value of the number from the first selected collection is Δ1, and the value of the number from the second selected collection is Δ2. It is concluded that the first and second texts belong to one author, if |Δ1-Δ2|≤0.01, and otherwise the authors are different.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to maxillofacial surgery. Bone and soft tissue defects of the maxillofacial region are eliminated by distributing the defect bed from transfacial access in different planes. After exposing the bone fragments of the jaw, a facial artery, a front vein and an external jugular vein are excised in the submandibular region. Fibular autograft is lifted. From a vertical incision in a projection of a fibular bone separation of an intermuscular partition between an inferior and soleus muscles is performed. Thereafter, the outer surface of the fibular bone is exposed. Front muscle group is prepared. Interosseous septum is detected and dissected. Posterior muscle group is prepared. Vascular bundle, a fibular artery and two veins are visualized. Adipofascial area is separated from the skin at the level of the perforating vent in accordance with preoperative planning. Autograft is modelled according to stereolithographic patterns prepared by intraoperative patterns. In places of planned osteotomy, periosteum and soft tissues are stripped minimizing their damage. Subperiosteal wedge-shaped osteotomy is performed. Obtained fragments are fixed between themselves at angle of 110–120 degrees, thereby obtaining the missing portion of the jaw with the fat component on the perforating vein from the fibular artery. After the vascular bundle is cut off in the donor zone with the autograft, a bone defect of the jaw is simultaneously replaced, as well as a soft tissue defect by adding and distributing an adipofascial platform of a fibular flap on a perforating vertebral artery from the transfacial approach in a prepared cavity. Bone portion of the autograft is fixed to the jaw stump using titanium mini-plates and mini-screws. Soft-tissue component is represented by an adipofacial flap combined with a bone autograft on a perforating vein from the fibular artery separated from a muscle thickness - a long flexor muscle of the thumb and rotated into a pre-created subcutaneous fat pocket. 
     EFFECT: method allows simultaneous elimination of bone and soft tissue defects of maxillofacial area, restoration of lower jaw contour, volume of soft tissues of adjoining areas and aesthetic rehabilitation of patients with maxillofacial defects.

Abstract: FIELD: medicine. 
     SUBSTANCE: group of inventions relates to a method for positioning a medical instrument for invasive surgery, X-ray contrast coordinate grid and a stereotaxic holder of the medical instrument for use when performing said method. Method comprises steps of determining a position of a passage for a medical instrument, collecting data of a specific patient, optimum position is selected to place an orienting device in the form of a stereotaxic holder of a medical instrument. At the stage of collecting data, determining the value of the displacement of the surface of the patient's body during breathing and the corresponding amplitude of respiratory movements, X-ray contrast linear marker is placed on the table under the patient's body in the axial plane of the operation object. On the patient's body surface in the area of the proposed operation, an X-ray contrast coordinate grid is placed so that the internal cell bridges are oriented in the sagittal plane, jumpers of external cells are oriented in axial plane. X-ray contrast coordinate grid is made in the form of a rectangular frame with transverse bridges forming internal rectangular cells. On each of the transverse sides of the frame there is a row of external rectangular cells. Value of the displacement of the patient's body surface during respiration is estimated by the displacement of the outer cell bridges relative to the linear marker on the table and relative to the line, generated by laser illumination of diagnostic equipment. If the body surface is displaced to 30 mm, a marker is used to draw lines in the axial and sagittal planes to mark the insertion point of the medical instrument. Stereotaxic holder equipped with four pairs of X-ray contrast marks in the form of parallel projections is installed on this place, arranged on the base on both sides of the bracket attachments, wherein the axial and sagittal marking lines pass between the projections. 
     EFFECT: higher accuracy of positioning of medical instrument in conditions of various movements of human body during operation.
