The Children-of-Twins design was used to test whether associations between marital conflict frequency and conduct problems can be replicated within the children of discordant twin pairs. A sample of 2,051 children (age 14-39 years) of 1,045 twins was used to estimate the genetic and environmental influences on marital conflict and determine whether genetic or environmental selection processes u...

Fetal surgery has become a clinical reality, with interventions for twin-to-twin transfusion syndrome (TTTS) and spina bifida demonstrated to improve outcome. Fetal imaging is evolving, with the use of 3D ultrasound and fetal MRI becoming more common in clinical practise. Medical imaging analysis is also changing, with technology being developed to assist surgeons by creating 3D virtual models ...

We performed a matched case-control study to analyze the placental angioarchitecture, in particular the diameter of arterio-arterial (AA) anastomoses in monochorionic placentas from pregnancies with twin-twin transfusion syndrome (TTTS) compared to a control group of uncomplicated monochorionic placentas. Placental angioarchitecture was analyzed using colored dye injection. AA anastomoses were ...

Two beams of light can be quantum mechanically entangled through correlations of their phase and intensity fluctuations. For a pair of spatially extended image-carrying light fields, the concept of entanglement can be applied not only to the entire images but also to their smaller details. We used a spatially multimode amplifier based on four-wave mixing in a hot vapor to produce twin images th...

Health policy makers in Canada have swung between the twin poles of ensuring access and controlling costs. Recently, access has dominated. Reconciling these opposing ideals, rather than alternating between them, requires adding the concept of appropriateness, and recognizing that rapid access to unneeded care may do more harm than good. Several examples are given of resources wasted (and side e...

The Digital Twin (DT) is one of the most promising technologies in digital transformation market. A twin a virtual copy physical system that emulates its behaviour to predict failures and opportunities for change, prescribe actions real-time, optimise and/or mitigate unexpected events. Modelling rather complex task requires availability large amount information set accurate models adequately re...

We present an algorithm to solve multistage stochastic convex problems, whose objective function and constraints are nonlinear. It is based on the twin-node-family concept involved in the Branch-and-Fix Coordination method. These problems have 0–1 mixed-integer and continuous variables in all the stages. The non-anticipativity constraints are satisfied bymeans of the twin-nodefamily strategy. I...

Abstract Ethics is an essential component for the responsible clinical management of multiple gestation and decision-making about such pregnancies with pregnant women. The ethical concept of the fetus as a patient is presented as the basis for identifying a professionally responsible approach to selective termination, twin-to-twin transfusion syndrome, and to discordant beneficence-based obliga...

A video watermarking scheme is proposed in this paper using the concept of the secret sharing scheme. The owner’s mark is split into twin shares, where the shares are inserted into the video frames in the spatial domain in a simple manner. The detection algorithm uses a linear function applied to the twin shares to reconstruct the secret. This makes the watermarked video sequence robust against...

We applied multivariate models specifying genetic and environmental influences on adjectives describing each of the five personality domains specified in the Big Five Model of personality (BFM; Extraversion, Neuroticism, Agreeableness, Conscientiousness, and Openness). We selected the specific models to partition the observed covariance among the adjectives describing each domain into genetic a...
