introduction: complete androgen insensitivity syndrome (previously called testicular feminization) is specified by a 46 xy karyotype and negative sex chromatin, bilateral undescended testes, female genitalia appearance, and lack of mullerian derivatives. discussion: our medline search revealed that this is the first reported case of bilateral sertoli–leydig cell tumor (slct) in androgen insensi...

Bilateral spontaneous tubal ectopic pregnancy is the rarest form of extra uterine pregnancy. The diagnosis is usually made intraoperatively and levels of serum BHCG and ultrasound has not been useful in the diagnosis of bilateral tubal ectopic pregnancy.A 33-year-old woman with 8 weeks amenorrhea and sever lower abdominal pain was admitted. A transvaginal pelvic ultrasound revealed left adnexal...

Non-syndromic bilateral humeroradial synostosis is a very rare congenital anomalies of the upper limbs. This condition often occurs in conjunction with various syndromes and is associated with a positive family history. Herein, we report a 6 year old boy with non-syndromic bilateral humeroradial synostosis, without aplasia, hypoplasia or family history. Both elbows were constant at 90 degrees f...

This paper identifies mechanisms that are implementable even when the planner cannot commit to the rules of the mechanism. The standard approach is to require mechanism to be robust against redesign. This often leads nonexistence of acceptable mechanisms. The novelty of this paper to require robustness against redesigns that are themselves robust against redesigns that are themselves robust aga...

Opportunism is a central construct in exchange theory. Economists contend that despite the firm’s best efforts to erect governance structures that reduce opportunism and preserve outcomes, there is always some opportunism that remains once the transaction is in place. Despite this, there are few studies that systematically investigate the safeguarding efficacy of relationship attributes in the ...

We consider non-cooperative environments in which two players have the power to commit but cannot sign binding agreements. We show that by committing to a set of actions rather than to a single action, players can implement a wide range of action profiles. We give a complete characterization of implementable profiles and provide a simple method to find them. Profiles implementable by bilateral ...

Endowing the negotiation agent with a learning ability such that a more beneficial agreement might be obtained is increasingly gaining emphasis in agent negotiation. In this paper, we present a novel bilateral negotiation model based on Bayesian learning to enable self-interested agents to adapt negotiation strategies dynamically during the negotiation process. Specifically, we assume that two ...
