A hollow-core photonic bandgap fiber polarizer may include a core, an inner cladding surrounding the core, the inner cladding including a plurality of capillaries, and an outer cladding at least partially surrounding the inner cladding. A section of the capillaries distal to the core is asymmetric relative to a section of the capillaries proximal to the core.

The present invention relates to a method for splicing a conventional single mode fiber and a photonic crystal fiber having a small core. The method, relying upon an offset fusion splicer, applies repeated arc discharges having weak current and short duration. The method results in a low loss between 1.5 dB to less than 0.5 dB.

A signal analysis system and method for analyzing an input signal acquired from a mechanical system. The mechanical system may include at least one rotating apparatus. The signal analysis system may include an input for receiving samples of an input signal acquired from the mechanical system, wherein the input signal is sampled in time, and wherein the input signal comprises a plurality of order components. The signal analysis system may also include a processor coupled to the input and a memory medium coupled to the processor which stores analysis software. The processor may be operable to execute the analysis software to: (a) perform an invertible joint time-frequency transform on the input signal to produce a first array of coefficients which depend on time and frequency; (b) generate a modified array of coefficients from the first array of coefficients, wherein the modified array of coefficients corresponds to a desired subset of the plurality of order components; and (c) generate a time domain signal from the modified array of coefficients. The signal analysis system may also include a presentation device coupled to the processor which is operable to present the time domain signal to a user. The time domain signal is useable in analyzing operation of the rotating apparatus in the mechanical system.

A signal analysis system and method for analyzing an input signal acquired from a mechanical system. The mechanical system may include at least one rotating apparatus. The signal analysis system may be configured to: (a) receive samples of the input signal, (b) perform an invertible joint time-frequency transform (e.g. a Gabor transform) on the samples of the input signal to produce a first array of coefficients which depend on time and frequency, (c) compute an instantaneous rotation frequency signal, (d) select first coefficients from the first array which correspond to one or more order components in the input signal, i.e. one or more multiples of the instantaneous rotation frequency signal, (e) generate a time domain signal from the first coefficients, and (f) present the time domain signal to a user on a presentation device. The signal analysis system may generate the time domain signal from the first coefficients by performing an inverse joint time-frequency transform on the first coefficients.
摘要:
Described herein is the discovery of novel PSMA-specific peptides, which were identified through a novel combinatorial biopanning method. One of the novel PSMA-specific peptides discovered, GTIQPYPFSWGY (or GTI) (SEQ ID NO: 2), exhibits high binding affinity and selectivity to PSMA and PSMA-positive prostate cancer cells. It was found that GTI can mediate internalization of the apoptotic KLA peptide to PSMA-positive LNCaP cells and induce cell death. Moreover, a FAM-labeled GTI peptide shows a high and specific tumor uptake in nude mice bearing human prostate cancer xenografts. It was demonstrated that the GTI peptide can be employed as a PSMA-specific ligand for prostate cancer diagnosis and/or for targeted drug delivery to prostate cancer cells.
