Understanding multi-dimensional mechanism design. 1 The Model Let M = {1, . . . , m} be a finite set of agents. Every agent has private information, which can be multi-dimensional. This is called his type. The space from which an agent draws his type is called his type space. Let Ti denote the type space of agent i ∈ M . We assume Ti ⊆ R n for some integer n ≥ 1. Let T m = ×mi=1Ti. Also, denote...

The notion of “incompatibility” of system variables arose with quantum mechanics; it is inconceivable in classical physics. Two expressions of incompatibility from the earliest days of quantum theory are the uncertainty principle of Heisenberg (measurement of one variable causes uncontrollable disturbance in other variables) and Bohr’s “complementarity” (not all variables have simultaneous “rea...

background: aub is a common cause of women’s referring to gynecologists. although hysteroscopy is known as the gold standard technique for diagnosing the cause of aub, sonohysterography is less invasive, and it is performed by general gynecologists. the purpose of this study was to evaluate the diagnostic performance of sonohysterography compared to the results of the endometrial biopsy, guided...

Software products do not provide consumption benefit unless a hardware product is installed in advance. In the market with this software – hardware relationship, a software producer sometimes finds that it is profitable to make its product compatible with only a certain hardware product. This incompatibility decision is considered as a vertical foreclosure. The conditions under which vertical m...

We survey four variants of RSA designed to speed up RSA decryption and signing. We only consider variants that are backwards compatible in the sense that a system using one of these variants can interoperate with systems using standard RSA.

in order to prepare polyurethane elastomers with acceptable physical properties and good biocompatibility, novel polyurethane networks were synthesized via curing reaction of epoxy-terminated polyurethane prepolymers (eups) with hexamethylene diamine. eups were prepared from reaction of glycidol with nco-terminated polyurethanes (itps). itps were also synthesized from reaction of one equivalent...

The basis of directional stimulus-response compatibility was studied using a task in which 128 participants moved a cursor into targets with a joystick, resembling the operation of certain industrial and construction equipment. Compatible and incompatible versions of three alternative compatibility principles were compared in all combinations. Visual Field (VF) compatibility was present if curs...

Compatibility between items, such as clothes and shoes, is a major factor among customer’s purchasing decisions. However, learning “compatibility” is challenging due to (1) broader notions of compatibility than those of similarity, (2) the asymmetric nature of compatibility, and (3) only a small set of compatible and incompatible items are observed. We propose an end-to-end trainable system to ...
