The cranking formula and the spurious behaviour of the mass parameters

We discuss some aspects of the approach of the mass parameters by means of the simple cranking model. In particular, it is well known that the numerical application of this formula is often subject to ambiguities or contradictions. It is found that these problems are induced by the presence of two derivatives in the formula. To overcome these problems, we state a useful ansatz and we develop a number of simple arguments which tend to justify the removal of these terms. As soon as this is done, the formula becomes simpler and easier to interpret. In this respect, it is shown how the shell effects affect the mass parameters. A number of numerical tests help us in our conclusions.Comment: version 3 corrigendum of the ansatz of section V, corrigendum of the legend of Fig3. Submission = text file + 5 figure

Perencanaan Moda Transprtasi Umum Rute Stasiun Tanjung Karang – Bandara Radin Inten II Lampung Selatan

This study consisted of two phases, namely collecting primary datas required, such as passengercharacteristics, choice of transport modes, flight datas, the number of passengers on certainperiod of time, distance and travel time from the Tanjung Karang Station to Radin Inten II SouthLampung Airport. Then analyze it with some methods that are used as conclusion parameters.This study uses several parameters used as reference for the planned mode of transportationplanning, i.e. the percentage of the characteristics and mode choice questionnaire results,multinomial logistic, simple linear regression, and performance planning mode of transportationof the plan.From the analysis of the datas percentage of the number of passengers with journey from BandarLampung origin who have the willingness to switch to the planned mode of transportationamounted to 96.67% or 72.75% of total passenger aircraft. The approximate number ofpassengers who will use public transport development plan based on the number of passengers 5years ie in 2019 amounted to 3,057 people per day. Planned modes of transportation wereplanned start the movement from 05.00 am to 07.00 pm with a departure time between busvulnerable for 15 minutes. As for the trip Radin Inten II Airport South Lampung - Tanjung KarangStation planned start movement from 07.00 am to 09.00 pm with a departure time of 15 minutesvulnerable. Based on the results of the processing of survey data obtained estimates of the numberof passengers in 2019 as many as 27 passengers per trip. Therefore it is required the type oftransport that meet these criteria are buses with a capacity of 35 passengers or so-called mediumbus. Performance planning public transportation based on the results of the questionnaire surveydata processing and some suggestions of passenger aircraft with the results of the servicefrequency of 4 veh / hour, 15-minute headway time, load factor of 77.14%, cycle time of 150minutes, the vehicle needs a number 12 vehicles, vehicle mileage per day amounted to 282 km,traveling speed of not more than 100 km / hour, mileage per trip of 23.5 km

Iranian Dietary Patterns and Risk of Colorectal Cancer

Background: Role of diet on colorectal cancer (CRC) has been considered in terms of single foods and nutrients, but less frequently in terms of dietary patterns in Iran. The objective of this study was to determine the association between Iranian dietary patterns and CRC. Methods: This case-control study was conducted in four hospitals in Tabriz City of Iran including 414 participants aged 35-75 years: 207 cases with CRC confirmed by pathology and colonoscopy findings were selected and 207 controls free of neoplastic conditions and diet-related chronic diseases (from the same hospital at the same period for the cases). Dietary data were assessed using a 123-item semi-quantitative food frequency questionnaire. Two dietary patterns were found by using of Principal Component Analysis (PCA) method;"Healthy pattern" and "Iranian pattern". Multivariate logistic regression analysis was used to estimate adjusted odds ratios (OR) for relationship between dietary patterns and colorectal cancer. Results: After adjusting for confounding factors, the Iranian dietary pattern was significantly associated with an increased odds of colorectal cancer (OR=1.46; 95 Confidenec Interval (CI)=1.05-2.19) while a reduced odds of colorectal cancer was observed with the Healthy dietary pattern (OR=0.18; 95 CI=0.091-0.47). Conclusion: Iranian dietary pattern (IDP) seems to increase the odds of colorectal cancer and protective effect of Healthy dietary pattern

Low-lying quadrupole collective states of the light and medium Xenon isotopes

Collective low lying levels of light and medium Xenon isotopes are deduced from the Generalized Bohr Hamiltonian (GBH). The microscopic seven functions entering into the GBH are built from a deformed mean field of the Woods-Saxon type. Theoretical spectra are found to be close to the ones of the experimental data taking into account that the calculations are completely microscopic, that is to say, without any fitting of parameters.Comment: 8 pages, 4 figures, 1 tabl

High-Performance Atomically-Thin Room-Temperature NO2 Sensor.

The development of room-temperature sensing devices for detecting small concentrations of molecular species is imperative for a wide range of low-power sensor applications. We demonstrate a room-temperature, highly sensitive, selective, stable, and reversible chemical sensor based on a monolayer of the transition-metal dichalcogenide Re0.5Nb0.5S2. The sensing device exhibits a thickness-dependent carrier type, and upon exposure to NO2 molecules, its electrical resistance considerably increases or decreases depending on the layer number. The sensor is selective to NO2 with only minimal response to other gases such as NH3, CH2O, and CO2. In the presence of humidity, not only are the sensing properties not deteriorated but also the monolayer sensor shows complete reversibility with fast recovery at room temperature. We present a theoretical analysis of the sensing platform and identify the atomically sensitive transduction mechanism

A semi-parametric approach to estimate risk functions associated with multi-dimensional exposure profiles: application to smoking and lung cancer

A common characteristic of environmental epidemiology is the multi-dimensional aspect of exposure patterns, frequently reduced to a cumulative exposure for simplicity of analysis. By adopting a flexible Bayesian clustering approach, we explore the risk function linking exposure history to disease. This approach is applied here to study the relationship between different smoking characteristics and lung cancer in the framework of a population based case control study
