This is the third column in our series explaining the new OMG Portable Object Adapter. An Object Adapter is the CORBA component responsible for adapting CORBA’s concept of objects to a programming language’s concept of servants. As you’ll recall from previous columns [1, 2], CORBA objects are “abstract” entities defined by IDL interfaces. Likewise, servants are “concrete” implementations of COR...

Mobile communications are nowadays highly developed thanks to the multiplicity of mobile devices. Some communications pass directly between mobile nodes (because the latters have direct connections between them), while for others, the mobile node must pass through a point of attachment (PoA). In the latter case, when the PoA falls down, all mobile nodes that are attached to him losing communica...

Although studies have shown that chemokines are pyrogenic when injected into the brain, there are no data indicating which cell types and receptors in the CNS are employed by chemokines such as CCL3 (synonym: MIP-1α) to induce fever in rats. We aimed to study, whether CCL3 induces fever when injected directly into the thermoregulatory center within the pre-optic area (POA). Moreover, we investi...

The aim of this immunohistochemical study was to evaluate the distribution of kisspeptin neurons in the preoptic area (POA) of gonadally intact adult male and female rhesus monkeys, and to determine whether imposition of an estradiol (E2)-positive feedback signal in the castrate male increased kisspeptin in the POA. Additionally, kisspeptin in the POA of the intact female was examined during an...

This paper addresses computations of a robustly safe region on the state space for uncertain constrained systems subject to disturbances based on a probabilistic approach. We first define a probabilistic output admissible (POA) set. This set is a subset of the state space which excludes with high probability initial states violating the constraint. Then, an algorithm for computing the POA set i...

Oxalicumone A (POA), a novel dihydrothiophene-condensed chromone, was isolated from the marine‑derived fungus Penicillium oxalicum. Previous reports demonstrated that POA exhibits strong activity against human carcinoma cells, thus it has been suggested as a bioactive anticancer agent. To research the toxic effect of POA on cultured normal epithelial human kidney‑2 (HK‑2) cells and evaluate its...

The Price of Anarchy (PoA) is a measure that compares the ratio between the maximum and minimum of a cost function evaluated at any Nash equilibrium of a game. There have been many results that bound the highest PoA for certain classes of games, but little has been done to explore the distribution of the PoA over a set of games. This project proposes a method to empirically evaluate this distri...

We identify how to share costs locally in weighted congestion games with polynomial cost functions to minimize the worst-case price of anarchy (POA). First, we prove that among all cost-sharing methods that guarantee the existence of pure Nash equilibria, the Shapley value minimizes the worst-case POA. Second, if the guaranteed existence condition is dropped, then the proportional cost-sharing ...

BACKGROUND Completion of advance directives (ADs) and power of attorney (POA) documents may protect a person's autonomy in future health care situations when the individual lacks decisional capacity. As such situations become naturally much more common in old age, we specifically aimed at providing information on (i) the frequency of ADs/POA in oldest-old individuals and (ii) factors associated...
