Weak sharp minima for interval-valued functions and its primal-dual characterizations using generalized Hukuhara subdifferentiability [PDF]
arXiv, 2021 This article introduces the concept of weak sharp minima (WSM) for convex interval-valued functions (IVFs). To identify a set of WSM of a convex IVF, we provide its primal and dual characterizations. The primal characterization is given in terms of $gH$-directional derivatives. On the other hand, to derive dual characterizations, we propose the notions

Fertility & Reproduction, 2023 Background and Aims: Embryo aneuploidy is caused by many factors, including patient age, sperm quality and sperm selection method. There are several methods for selecting sperm, ICSI (intracytoplasmic sperm injection) and IMSI (intracytoplasmic ...

Generalized Hukuhara Weak Subdifferential and its Application on Identifying Optimality Conditions for Nonsmooth Interval-valued Functions [PDF]
arXiv, 2022 In this article, we introduce the idea of $gH$-weak subdifferential for interval-valued functions (IVFs) and show how to calculate $gH$-weak subgradients. It is observed that a nonempty $gH$-weak subdifferential set is closed and convex. In characterizing the class of functions for which the $gH$-weak subdifferential set is nonempty, it is identified ...

Human Reproduction, 2011 To optimize success rates of IVF, selection of the most viable embryo(s) for transfer has always been essential, as embryos that are cryopreserved are thought to have a reduced chance of implanting after thawing. Recent developments challenge this concept.

Automated identification of blastocyst regions at different development stages
Scientific Reports, 2023 The selection of the best single blastocyst for transfer is typically based on the assessment of the morphological characteristics of the zona pellucida (ZP), trophectoderm (TE), blastocoel (BC), and inner cell-mass (ICM), using subjective and observer ...

Is Cleavage Stage Multinucleation Indicative of Lower Pregnancy Potential in Euploid Blastocysts?
Fertility & Reproduction, 2022 Background: Cleavage stage multinucleation is a morphological assessment IVF labs may use to rank embryos for transfer, as blastocysts that were multinucleated at the 2-cell or 4-cell stage have a lower live birth rate (LBR) compared to blastocysts that ...

Bridging Dense and Sparse Maximum Inner Product Search [PDF]
, 2023 Maximum inner product search (MIPS) over dense and sparse vectors have progressed independently in a bifurcated literature for decades; the latter is better known as top-$k$ retrieval in Information Retrieval. This duality exists because sparse and dense vectors serve different end goals.

Parenting and child development in families with a child conceived through embryo donation [PDF]
, 2007 Concerns have been raised regarding the potentially negative effects of conception using donated embryos on parenting and child development. Findings are presented of an exploratory study of families with a child conceived through embryo donation. Twenty-

Reproductive Biomedicine & Society Online, 2016 Since the 19th century the Iranian state has been concerned with the size of its population, and policies directed to its increase or decrease have been closely involved with the purpose of nation building. None of these policies have been particularly successful, except for the effective family planning campaign of the 1980s that led to a remarkable ...

Generalized Hukuhara Hadamard Derivative of Interval-valued Functions and Its Applications to Interval Optimization [PDF]
arXiv, 2022 In this article, we study the notion of gH-Hadamard derivative for interval-valued functions (IVFs) and its applications to interval optimization problems (IOPs). It is shown that the existence of gH-Hadamard derivative implies the existence of gH-Frechet derivative and vise-versa.
