In news:

IUDs are on the verge of a remarkable return to popularity.
Only two IUDs are on the market in the US, but two more are in late-stage clinical trials.
In 2005, ACOG released a practice bulletin urging greater use of IUDs , and in 2007, it suggested that IUDs "should be considered as first-line choices" for teenagers.
The National Institutes of Health sponsored the Women's Health Study beginning in 1976 to assess the relationship between IUD 's and pelvic infections among patients in 16 hospitals in 9 cities.
But it is certain to renew debate about the value of IUD 's, which are now used by an estimated 1.5 million women in this country, or 3 percent of contraceptive users, less than half the number in 1982.
Despite Widespread Fear, IUD 's Are Safe for Many Women.
New alarms about IUD 's were raised last week when a Minnesota woman, Esther R Kociemba, was awarded $8.75 million in her case against G.
In reflection of the article "Effective Enough," cited on page A5, Sept 21, concerning IUD's as a positive answer to teenage pregnancy - on the feminine side.
IUDs Only Promote An Unsafe, Promiscuous Lifestyle.
Unplanned pregnancies 20 times more likely on birth control pill than IUD, study finds.
IUDs, implants vastly more effective than the pill.
IUDs, implants urged for teen girls' birth control .
At issue are contraceptives such as Plan B and IUDs.
Will Obamacare make the IUD more prevalent.
For years now, the IUD has supposedly been poised for its big comeback.

In science:

We consider in the paper the distributional aspect of the above three types of records in two typical cases when the pi ’s are iud in the hypercube [0, 1]d and in the d-dimensional simplex, respectively.
Multivariate records based on dominance
The effective weak Hamiltonian for s → ud ¯u can be decomposed into pieces symmetric (Iud = 1) and antisymmetric (Iud = 0) under the interchange of the final u and d quarks.
Present and Future Aspects of CP Violation
The Iud = 0 piece receives an enhancement from perturbative QCD, while the Iud = 1 piece is slightly suppressed.35 The Iud = 0 piece contributes only to ∆I = 1/2 amplitudes, since the only other quark carrying isospin in the process is a ¯u quark.

The evaluation of f t-values involves the inverse of the product of Iud , Iuu and Idd squared.
