FiMAP: A fast identity-by-descent mapping test for biobank-scale cohorts. by Han Chen, Ardalan Naseri, Degui Zhi

“…Here we leverage the identity-by-descent (IBD) segments inferred from a random projection-based IBD detection algorithm in the mapping of genetic associations with complex traits, to develop a computationally efficient statistical test for IBD mapping in biobank-scale cohorts. …”

Inbreeding depression is associated with recent homozygous-by-descent segments in Belgian Blue beef cattle by Maulana Mughitz Naji, José Luis Gualdrón Duarte, Natalia Soledad Forneris, Tom Druet

“…We computed estimators of F based on the pedigree information (F PED), on the correlation between uniting gametes (F UNI), on the genomic relationship matrix (F GRM), on excess homozygosity (F HET), or on homozygous-by-descent (HBD) segments (F HBD). Results F UNI and F GRM were sensitive to used allele frequencies, whereas F HET and F HBD were more robust. …”

On the Complexity of Steepest Descent, Newton's and Regularized Newton's Methods for Nonconvex Unconstrained Optimization Problems. by Cartis, C, Gould, N, Toint, P

Double-descent curves in neural networks: a new perspective using Gaussian processes by El Harzli, O, Cuenca Grau, B, Valle-Pérez, G, Louis, AA

“…Double-descent curves in neural networks describe the phenomenon that the generalisation error initially descends with increasing parameters, then grows after reaching an optimal number of parameters which is less than the number of data points, but then descends again in the overparameterized regime. …”

Descent rate models of the synchronization of the Quasi-Biennial Oscillation by the annual cycle in tropical upwelling by Rajendran, K, Moroz, I, Osprey, S, Read, P

“…A heuristic descent rate model for the zero wind line is described, and is shown to capture many of the synchronization features seen in previous studies of the QBO. …”

Descent groups among cognatic societies: the Dusun tribes of Inland Sabah/North Borneo by Sanen Marshall, Veronica Petrus Atin, Low, Kok On, Lim, Alice, Nelson Adeh

“…In the following discussion, the authors present a comparison of various societies in Borneo which includes for the first time a society that features descent groups. The claim that the Dusun society of the Upper Labuk River in inland North Borneo or Sabah possesses descent groups is one that has yet to be acknowledged in the wider Borneo literature. …”

A new gradient method via quasi-Cauchy relation which guarantees descent by Abu Hassan, Malik, Leong, Wah June, Farid, Mahboubeh

“…We propose a new monotone algorithm for unconstrained optimization in the frame of Barzilai and Borwein (BB) method and analyze the convergence properties of this new descent method. Motivated by the fact that BB method does not guarantee descent in the objective function at each iteration, but performs better than the steepest descent method, we therefore attempt to find stepsize formula which enables us to approximate the Hessian based on the Quasi-Cauchy equation and possess monotone property in each iteration. …”

A Virgilian Descent into Gendered Old Age: London katabasis in Margaret Drabble’s The Seven Sisters by Daniel Nisa Cáceres

“…This close reading of the trope will not only provide a critical insight into Drabble’s subversive reworking of Aeneas’s descent to the Underworld from a female-centred perspective, but will also explore how the mythical resignification of the London urban landscape mediates an ongoing redefinition of women’s old age and its tense power relations with the past, the present and the future.…”
