Classical results on secure multi-party computation (MPC) imply that fully secure computation, including fairness (either all parties get output or none) and robustness (output delivery is guaranteed), is impossible unless a majority of the parties is honest. Recently, cryptocurrencies like Bitcoin where utilized to leverage the fairness loss in MPC against a dishonest majority. The idea is tha...

the present research was conducted with the aim of investigating the effect of high intensity interval and medium continuous training on anaerobic and aerobic power female basketball players. the research method was quasi-experimental with pretest and posttest, and included all female basketball players in firoozkooh city, tehran province, iran in 2015. twenty female basketball players were enr...

By quick technological advancements in industrial control processes, major industries demand higher power quality. According to IEEE 1159-1995 standard, any problems in voltage, current or freq‌ue‌ncy that lead to the error or malfunctions in electrical equipment are considered as a power quality problem. Among the power quality phenomena, voltage sag has been an important problem for power sys...

OBJECTIVES To compare the retinal nerve fiber layer (RNFL) thickness and retinal sensitivity in the normal visual hemifield of glaucomatous eyes with localized visual field loss with those of normal eyes and eyes with suspected glaucoma, and to evaluate the relationship between RNFL atrophy and glaucoma severity. METHODS One randomly selected eye of each subject underwent standard automated p...

In a previous paper we show how social pressure, in the form of informal sanctions by outside observers, affects choices made by defendants and prosecutors, both with respect to plea offers and to decisions to proceed to trial. In that paper, we assume that the defendant's guilt or innocence is his private information, and that evidence at trial is imperfect and may result in errors in convicti...

We introduce a novel region-based video compression framework that uses a morphological operation to eeciently capture motion correspondences between consecutive frames in an image sequence. Our coder is built on the observation that the motion eld associated with typical image sequences can be segmented into component motion sub-eld \clusters" associated with distinct objects or regions in the...

Compensating transactions are intended to handle situations where it is required to undo either committed or uncommitted transactions that affect other transactions, without resorting to cascading aborts. This stands in sharp contrast to the standard approach to transaction recovery where cascading aborts are avoided by requiring transactions to read only committed data, and where committed tra...

We describe the StAC language which can be used to specify the orchestration of activities in long running business transactions. Long running business transactions use compensation to cope with exceptions. StAC supports sequential and parallel behaviour as well as exception and compensation handling. We also show how the B notation may be combined with StAC to specify the data aspects of trans...

Scholars frequently argue whether the sharp rise in chief executive officer (CEO) pay in recent years is “efficient” or is a consequence of “rent extraction” because of the failure of corporate governance in individual firms. This article argues that governance failure must be conceptualized at the market rather than the firm level because excessive pay increases for even relatively few CEOs a ...
