Abstract: Изобртеение относится к области медицины и касается способа прогнозирования синхронного лимфогенного метастазирования у больных немелкоклеточным раком легкого после неоадъювантной химиотерапии. Сущность способа заключается в том, что проводят оценку уровня лейкоцитов, тромбоцитов, определяют концентрацию С-реактивного белка. Далее рассчитывают вероятность наличия лимфогенного метастазирования по значению уравнения регрессии Y по формуле: Y = -64,8 + 37,5 X1 + 4,2X2 - 30,4 Х3, где: -64,8 - значение коэффициента регрессии свободного члена; X1 - уровень лейкоцитов в крови, Х1=1 при уровне лейкоцитов в крови менее 4×10 9 /л, X1=2 при уровне лейкоцитов в крови (4-7)×10 9 /л, Х1=3 при уровне лейкоцитов в крови (7-10)×10 9 /л, X1=4 при уровне лейкоцитов в крови более 10×10 9 /л; Х2 - уровень тромбоцитов в крови, Х2=1 при уровне тромбоцитов в крови меньше 100×10 9 /л, Х2=2 при уровне тромбоцитов в крови (100-200)×10 9 /л, Х2=3 при уровне тромбоцитов в крови (200-300)×10 9 /л, Х2=4 при уровне тромбоцитов в крови более 300×10 9 /л; Х3 - концентрация СРБ в крови, Х3=1 при концентрация СРБ в крови 5 мг/л, Х3=2 концентрация СРБ в крови более 5 мг/л. Вероятность наличия лимфогенных метастазов Р определяют по формуле: P = e Y /(1+e Y ), где e=2,72. При вероятности Р≥50% определяют высокий риск наличия лимфогенных метастазов, при вероятности Р<50% - низкий риск наличия лимфогенных метастазов. Использование способа позволяет с высокой точностью определить тактику лечения в послеоперационном периоде. 2 пр.

Abstract: Изобретение относится к области радиосвязи и может найти применение в системах беспроводного доступа, сухопутной подвижной и спутниковой связи, призванных функционировать в условиях ограничений на выделенный частотный ресурс. Технический результат - повышение спектральной эффективности системы связи при обеспечении высокой структурной скрытности. В многоканальном спектрально-эффективном передатчике с квадратурной амплитудно-инверсной модуляцией с когерентным частотно-кодовым разделением каналов осуществляется М-ичная амплитудно-инверсная модуляция нелинейных ортогональных кодовых последовательностей. При модуляции сигналов в каждой информационной группе, состоящей из m двоичных символов, один из них используется для определения знака нелинейной ортогональной кодовой последовательности, а остальные (m-1) символов определяют амплитуду этой последовательности. Далее происходит перемножение нелинейной маскирующей последовательности с уже промодулированными ортогональными кодовыми последовательностями. В результате перемножения данных последовательностей значительно повышается структурная скрытность сигнала. Результирующие последовательности, полученные в процессе перемножения нелинейной маскирующей последовательности и модулированной нелинейной ортогональной кодовой последовательности, осуществляют модуляцию квадратурных составляющих когерентной частоты, после чего осуществляют линейное сложение модулированных квадратурных составляющих. 3 ил.
