Pesky trachoma suspect finally caught.
AIM Face seeking flies have long been thought to transmit Chlamydia trachomatis, the causative agent of trachoma, but this has never been proven. The four criteria proposed by Barnett, previously used to incriminate other arthropods suspected of transmitting disease, were examined. One of these criteria remains unmet: the repeated demonstration of the presence of C trachomatis on flies. The aut...
متن کاملReceptor–ligand binding: ‘catch’ bonds finally caught
Leukocyte recruitment to sites of inflammation is initiated by the selectin family of adhesion receptors. Recent research reveals that P-selectin binding to its ligand exhibits 'catch' to 'slip' bond transition that may help explain the shear threshold phenomenon.
متن کاملNo more pesky learning rates
The performance of stochastic gradient descent (SGD) depends critically on how learning rates are tuned and decreased over time. We propose a method to automatically adjust multiple learning rates so as to minimize the expected error at any one time. The method relies on local gradient variations across samples. In our approach, learning rates can increase as well as decrease, making it suitabl...
متن کاملPrime suspect.
Background: Human T-lymphotropic virus type-1 (HTLV-1) causes adult T-cell leukemia/ lymphoma and is linked to a number of lymphocyte-mediated disorders. HTLV-1 contains both regulatory and accessory genes in four pX open reading frames. pX ORF-II encodes two proteins, p13 and p30, whose roles are still being defined in the virus life cycle and in HTLV-1 virus-host cell interactions. Proviral c...
متن کاملNo More Pesky Learning Rates: Supplementary Material
If we do gradient descent with η * (t), then almost surely, the algorithm converges (for the quadratic model). To prove that, we follow classical techniques based on Lyapunov stability theory (Bucy, 1965). Notice that the expected loss follows E J θ (t+1) | θ (t) = 1 2 h · E (1 − η * h)(θ (t) − θ *) + η * hσξ 2 + σ 2 = 1 2 h (1 − η * h) 2 (θ (t) − θ *) 2 + (η *) 2 h 2 σ 2 + σ 2 = 1 2 h σ 2 (θ (...
