This paper considers two phenomena in Tz'utujil (Mayan) phonology: final sonorant devoicing and aspiration of plain (pulmonic) stops affricates. Both occur word-internally coda position, as well word-finally. I present an Optimality-Theoretic (OT) analysis which accounts for both these via positional constraints on [spread glottis] ([SG]). also attested variation across the Mayan language famil...

With the aid of the creation operators introduced in our previous works, we show how to construct a basis of the space of quasi-local operators for the homogeneous XXZ chain.

Eigenstates of the linear combinations a 2 + βa †2 and ab + βa † b † of two boson creation and annihilation operators are presented. The algebraic procedure given here is based on the work of Shanta et al. 1994] for constructing eigenstates of generalized annihilation operators.

Based on the statistical data from National Bureau of Statistical of China, this paper shows the correlationship between the energy consumption of the provinces and temperature of corresponding capitals. After that Shanghai is researched as an example, and an forecast of Shanghai’s temperature after 20 years is draw out on condition that the energy consumption of this city keeps the same increa...

The new closed form solutions of the (2+1)-dimensional Zabolotskaya–Khokhlov equation are constructed by using the similarity transformations method via Lie group theory. The Zabolotskaya–Khokhlov equation has been reduced into a new partial differential equation with smaller number of independent variables. Further using the similarity transformations method the new partial differential equati...

BACKGROUND With the addition of laparoscopic vertical sleeve gastrectomy (SG) to the bariatric surgery procedural toolkit, patients desiring a restrictive bariatric procedure often choose between adjustable gastric banding (LAGB) and SG. One study compared quality of life after these 2 procedures and found no difference. The purpose of our study was to re-evaluate the postoperative quality of l...

Hirschsprung's disease (HD) is a development disorder of the enteric nervous system in which the altered innervation explains the inability of the aganglionic segment to relax. Impairment of cytoskeleton in SMC of aganglionic bowel has been shown. Sarcoglycan subcomplex (SG) may support the development and maintenance of muscle cells. We examined the SG subunit expression in colonic aganglionic...
