A variety of applications of Satisfiability Modulo Theories (SMT) require finding a satisfying assignment which optimizes some user-given function. Optimization in the context of SMT is referred to as Optimization Modulo Theories (OMT). Current OMT research is mostly dedicated to optimization in arithmetic domains. This paper is about Optimization modulo Bit-Vectors (OBV). We introduce two OBV ...

The Paris Agreement adopted in December 2015 during the COP21 conference stipulates that the increase in the global average temperature is to be kept well below 2C above “pre-industrial levels” and that efforts are pursued to limit the temperature increase to 1.5C above “pre-industrial levels.” In order to further increase public acceptance of these limits it is important to transparently place...

The Medieval Climate Anomaly (MCA) was the most recent pre-industrial era warm interval of European climate, yet its driving mechanisms remain uncertain. We present here a 947-year-long multidecadal North Atlantic Oscillation (NAO) reconstruction and find a persistent positive NAO during the MCA. Supplementary reconstructions based on climate model results and proxy data indicate a clear shift ...

The concentration of three metals, zinc, copper and chromium in roots, rhizomes, stems and leaves of Phragmites australis (common reed) and Scirpus maritimus, and in the corresponding sediment and water samples from Lia industrial area (Qazvin, Iran) were investigated to determine difference in distribution among plant organs. Data were collected at during 1-year period. Results showed that met...

Reed (1) isolated lipoic acid (LiA) from yeast and liver, and reported that this substance played an important role as one of the coenzymes in the oxidation of ƒ¿-keto acids. Sanadi (2, 3) reported that lipoamide (LiA-NH2), the amide of LiA, had greater activity than LiA as a coenzyme of ƒ¿-ketoglutraric dehy drogenase obtained from heart muscle. The authors (4) studied previously the serum lev...

OBJECTIVES To compare the pain during anesthesia and during the no-scalpel vasectomy procedure for local infiltration anesthesia (LIA), LIA supplemented with spermatic cord block (LIA + SCB), and no needle jet anesthesia. METHODS Bilateral no-scalpel vasectomy was performed in 323 patients during 2007. Of the 323 patients, 65 received LIA, 29 received LIA + SCB, and 227 received anesthesia us...
