Abstract: The present invention relates to an optical fiber with improved bend performance and manufacturing method thereof. The optical fiber (100) comprises a core region (108) defined by a core refractive index profile (200) and a cladding region (106) surrounding the core region defined by a cladding refractive index profile (400). Particularly, the core region has a first core (102) defined by a first core refractive index (RI) profile (202) and a first core RI max (?peak) and a second core (104) defined by a second core RI profile (204) and a second core RI max (?core). Moreover, the cladding region further comprises a first cladding (106) and a third cladding (110) composed of pure silica and a second cladding (108) composed of a down-doped silica, where the down-dopant is fluorine.

Abstract: The present invention relates to an optical fiber (100) comprising a core region (102) having radius R1 and a cladding region (104) having a radius R3. In particular, the core region (102) is defined along a central longitudinal axis (110) and the cladding region (104) is defined along the central longitudinal axis (110) of the optical fiber (100). Moreover, the optical fiber (100) has a Mode Field Diameter in a range of 8.5+/?0.3 microns at a wavelength of 1310 nanometers, a micro-bending loss of less than equal to 0.5 dB/Km at a wavelength of 1550 nanometers, macro-bending loss of less than 1 dB/Km at a wavelength 1550 nanometers. Further, the optical fiber (100) has a diameter of less than 210 microns.

Abstract: The present invention is directed to an undercoating composition comprising: a) a vinyl chloride-vinyl acetate copolymer obtained by polymerization of a co-monomer mixture comprising, based on the total weight of the co-monomers, from 85 to 98 wt. % of vinyl chloride, from 2 to 10 wt. % of vinyl acetate and from 0 to 5% by weight of a co-monomer selected from C2 to C8 olefins, vinylidene chloride and styrene; b) plasticizer comprising or consisting of at least one epoxidized natural oil; and, c) at least one aliphatic, cycloaliphatic or aromatic compound having a blocked isocyanate group, wherein said isocyanate group is blocked with a blocking agent capable of de-blocking at a temperature in the range of +/?20° C. compared to the de-blocking temperature of the corresponding isocyanate being blocked with nonylphenol.

Abstract: In one general aspect, a computer-implemented method can include scheduling a respective available open enrollment period for each of a plurality of cohort sessions for an online course, determining that a first cohort session included in the plurality of cohort sessions for the online course is open for enrollment, enrolling, based on determining the first cohort session is open for enrollment, a learner in the first cohort session, automatically tracking a progress for the enrolled learner, determining, based on automatically tracking the progress for the learner, that the learner is falling behind a predetermined schedule of course completion for the online course, and, based on determining that the learner is falling behind the predetermined schedule, automatically determining that a second cohort session included in the plurality of cohort sessions for the online course is open for enrollment, and enrolling the learner in the second cohort session.

Abstract: A composition derived from six plant materials: ((i) Herba epimedii (Yin Yang Huo) (ii) Fructus Psoraleae (Psoralea coryfolia) (Bu Gu Zhi) (iii) Radix Rehmanniae preparatae (Rehmannia glutinosa) (Shu Di) (iv) Cortex Eucommiae (Du Zhong) (v) Fructus Cnidii (She Chuang Zhi) (vi) Radix Astragali (Astragalus Membranaceus) (Huang Qi)) is useful in treating conditions linked to the activity of osteoblasts and/or osteoclasts, such as osteoporosis and other conditions relating to bone mass or the menopause; obesity; glucose intolerance; and diabetes.
