We present the proof search monad, a set of combinators that allows one to write a proof search engine in a style that resembles the formal rules closely. The user calls functions such as premise, prove or choice; the library then takes care of generating a derivation tree. Proof search engines written in this style enjoy: first, a one-to-one correspondence between the implementation and the de...

Cost contribution arrangements (CCAs) and Cost sharing agreements (CCAs) belong to the tools of modern finance management. Costs spend by associated enterprises on developing producing or obtaining assets, services or rights (in general benefits) are used for tax optimizing too. The main purpose of joint research and development, producing or obtaining benefits is to lower these costs as much a...

Causality discovery without manipulation is considered a crucial problem to a variety of applications, such as genetic therapy. The state-of-the-art solutions, e.g. LiNGAM, return accurate results when the number of labeled samples is larger than the number of variables. These approaches are thus applicable only when large numbers of samples are available or the problem domain is sufficiently s...

We consider regression when the predictor is measured with error and an instrumental variable is available. The regression function can be modeled linearly, nonlinearly, or nonparametrically. Our major new result shows that the regression function and all parameters in the measurement error model are identified under relatively weak conditions, much weaker than previously known to imply identif...

Although routinely informed of the benefits of fruits and vegetables, Americans eat far short of the recommended amounts. Instead of just telling people that fruits and vegetables are healthy, providing a compelling causal and teleological explanatory framework could increase both people’s conviction about their health benefits and commitment to increasing the amount and variety of fruits and v...

The Effect of Sanctions on the Job Finding Rate: Evidence from Denmark This paper investigates the effect of sanctions of unemployment insurance benefits on the exit rate from unemployment for a sample of Danish unemployed. According to the findings are that even moderate sanctions have rather large effects. For both males and females the exit rate increases by more than 50% following impositio...

Our paper provides an explanation why cost-of-living adjustment (COLA) provisions and their characteristics vary widely across U.S. industries. We develop models of optimal risk sharing between a firm and union to investigate the determinants of a number of contract characteristics. These include the presence and degree of wage indexing, the magnitude of deferred noncontingent wage increases, c...

Cereals are the major source of energy to good health over world. The and minor cereals consumed either processed semi with addition other food ingredients. contains nutrients like carbohydrates, proteins, minerals, vitamins, fat some having amount dietary fibre (soluble insoluble). Some especially colored rice, wheat, maize millets functional bioactive components such as polyphenols, tocophero...

Abstract. This paper proposes admittance matrix models to approach the behavior of six modern multiport functional blocks called: differential difference amplifier, differential difference operational floating amplifier, differential difference operational mirror amplifier, differential difference current conveyor, current backward transconductance amplifier and current differencing transconduc...
