Breakdown of the operator product expansion in the 't Hooft model

We consider deep inelastic scattering in the 't Hooft model. Being solvable, this model allows us to directly compute the moments associated with the cross section at next-to-leading order in the 1/Q^2 expansion. We perform the same computation using the operator product expansion. We find that all the terms match in both computations except for one in the hadronic side, which is proportional to a non-local operator. The basics of the result suggest that a similar phenomenon may occur in four dimensions in the large N_c limit.Comment: 4 page

Comment on "Length-dependent translation of messenger RNA by ribosomes"

In the recent paper of Valleriani {\it et al} [Phys. Rev. E {\bf 83}, 042903 (2011)], a simple model for describing the translation of messenger RNA (mRNA) by ribosomes is presented, and an expression of the translational ratio $r$, defined as the ratio of translation rate $\omega_{\rm tl}$ of protein from mRNA to degradation rate $\omega_p$ of protein, is obtained. The key point to get this ratio $r$ is to get the translation rate $\omega_{\rm tl}$. In the study of Valleriani {\it et al}, $\omega_{\rm tl}$ is assumed to be the mean value of measured translation rate, i.e. the mean value of ratio of the translation number of protein to the lifetime of mRNA. However, in experiments different methods might be used to get $\omega_{\rm tl}$. Therefore, for the sake of future application of their model to more experimental data analysis, in this comment three methods to get the translation rate $\omega_{\rm tl}$, and consequently the translational ratio $r$, are provided. Based on one of the methods which might be employed in most of the experiments, we find that the translational ratio $r$ decays exponentially with the length of mRNA in prokaryotic cells, and decays reciprocally with the length of mRNA in eukaryotic cells. This result is slight different from that obtained in Valleriani's study

Parameter Sensitivity in LSMs: An Analysis Using Stochastic Soil Moisture Models and ELDAS Soil Parameters

Integration of simulated and observed states through data assimilation as well as model evaluation requires a realistic representation of soil moisture in land surface models (LSMs). However, soil moisture in LSMs is sensitive to a range of uncertain input parameters, and intermodel differences in parameter values are often large. Here, the effect of soil parameters on soil moisture and evapotranspiration are investigated by using parameters from three different LSMs participating in the European Land Data Assimilation System (ELDAS) project. To prevent compensating effects from other than soil parameters, the effects are evaluated within a common framework of parsimonious stochastic soil moisture models. First, soil parameters are shown to affect soil moisture more strongly than the average evapotranspiration. In arid climates, the effect of soil parameters is on the variance rather than the mean, and the intermodel flux differences are smallest. Soil parameters from the ELDAS LSMs differ strongly, most notably in the available moisture content between the wilting point and the critical moisture content, which differ by a factor of 3. The ELDAS parameters can lead to differences in mean volumetric soil moisture as high as 0.10 and an average evapotranspiration of 10%–20% for the investigated parameter range. The parsimonious framework presented here can be used to investigate first-order parameter sensitivities under a range of climate conditions without using full LSM simulations. The results are consistent with many other studies using different LSMs under a more limited range of possible forcing condition

Identification of Lactic Acid Bacteria from Fermented Kimchi Sawi Ansabi (Brassica juncea L.) using Phenotypic Similarities

Latic acid bacteria play a significant role in the fermentation of food, such as kimchi, which is fermented vegetables. Sawi kampung ansabi is a vegetable cultivated by the Dayak people in Kalimantan during the rice farming season which can be fermented into kimchi. Based on phenotypic similaities, the aim of this study was to identify and acquire cultures of lactic acid bacteria on MRSA media (De Man Rogosa and Sharpe Agar) enriched 1% CaCO3 from kimchi sawi ansabi fermented food sawi ansabi. The results of the isolations were used to test 10 isolates of lactic acid bacteria using the MVSP (Multivariate Statistical Package) program, the UPGMA (Unweighted Pair Group Method with Arithmetic Average Mean) method based on the Simple Matching Coefficient and Jaccard Coefficient to form dendrograms. Simple Matching Coefficient analysis resulted 8 isolates suspected to be Lactobacillus plantarum with a similarity index of 94.6%, 1 suspected 91.9% to Lactobacillus dellbrueckii, and 1 suspected 91.9% to Pediococcus cerevisiae. The Jaccard Coefficient analysis resulted in 8 isolates suspected of Lactobacillus plantarum with a similarity index of 92.6%, 1 isolate suspected 87% to Lactobacillus dellbrueckii, and 1 isolate 88% to Pediococcus cerevisiae

Asymmetry of the ovale and spinous foramina in mediaeval and contemporary sculls in radiological examinations

The aim of this work was to evaluate the morphology and asymmetry of the ovale and spinous foramina. Examinations were carried out on 102 mediaeval and 85 contemporary male skulls. In both groups there predominated individuals who had died at mature (maturus) and adult (adultus) age. Radiological images in occipital projection were used in the study. Areas of the foramina ovale, distances between both openings and the distance from the midline running through the middle of the occipital foramen were calculated by means of PC software. The spinal foramen area could not be measured because of the too small surface accessible to the PC software used in our study. Correlation between the above measurements and cranial indexes (width-length and height-length) were calculated. Significant variety of the ovale and spinous foramina in size, shape, relation to each other and to the midline were analysed. Asymmetry of structure and location was observed in both examined groups of skulls. No cases of the lack of the ovale and spinous foramina were stated

Detailed petrophysical and geophysical characterization of core samples from the potential caprock-reservoir system in the Sulcis Coal Basin (Southwestern Sardinia - Italy)

In this work we present a methodology suitable to identify a caprock-reservoir system for the CO2 storage in the Sulcis Coal Basin (SW Sardinia - Italy). The petrophysical and geophysical characterizations indicate that the potential carbonate reservoir ("Miliolitico" Fm. Auct.) located at the base of the Eocene stratigraphic sequence in the mining district of the Sulcis Coal Basin, southwestern Sardinia, is heterogeneous but presents suitable reservoir zones for the storage of the CO2. The GPS data analysis indicates that the study area is stable, since it is characterized by a surface crustal deformation smaller than 1 mm/y

Does an early rural life influence selected health-related parameters of female university students?

Objective. The aim of the study was to define whether in a group of young women the place of residence in their childhood and adolescence, as well as moving from a rural to an urban area, have affected their biological condition. Materials and method. The data were obtained from 1,305 unmarried and childless women aged 18–25. The respondents were university students. Each person’s height, weight and waist circumference were measured, and the BMI, WHR, and WHtR indices were calculated. A survey was used to collect data on the females’ socio-economic status, their health condition and course of menstruation cycle. Results. In the whole sample, apart from WHR, there was no significant difference in anthropometric characteristics depending on the urbanization degree of the place of residence before commencing studies. In comparing the two groups of women, changing place of residence from a village to a city and from a city to another city, more differences were visible. Women of rural origin presented significantly higher values of BMI, waist circumference and WHtR than those from the city. They were also more frequently characterized by overweight and abdominal obesity. The women from other cities were characterized by underweight and too low amount of abdominal adipose tissue. Health problems were found in both groups. Students of rural origin more rarely declared changes in body weight and health condition after beginning studies. Students of urban origin were more often affected by sleeping problems and spine pains. Conclusions. The results of the study do not indicate that a change of place of residence has a stronger effect on the biological condition of rural women than their urban peers
