Diurnal temperature range (DTR) is an important meteorological component affecting the yield and protein content of winter wheat. The accuracy climate model simulations DTR will directly affect prediction wheat quality. Previous evaluations for worldwide or nationwide cannot answer which suitable estimation yield. We evaluated ability coupled intercomparison project phase 6 (CMIP6) models to si...

Increased clouds and precipitation normally decrease the diurnal temperature range (DTR) and thus have commonly been offered as explanation for the trend of reduced DTR observed for many land areas over the last several decades. Observations show, however, that the DTR was reduced most in dry regions and especially in the West African Sahel during a period of unprecedented drought. Furthermore,...

The relationship between precipitation deficits and extreme hot temperatures has been documented in observation and modeling studies. However, it is unclear whether and how increases in maximum temperatures will impact diurnal temperature range (DTR) extremes. Here, we used observational data sets from meteorological stations in China to examine the trends in high DTR extremes from 1971 to 2013...

The disrupt-then-reframe (DTR) influence technique involves confusing consumers with a disruptive message and then reducing ambiguity by reframing the message. Experiment 1 shows that the DTR technique increases retail sales in a supermarket setting. Experiment 2 shows that the DTR technique increases the willingness to pay to join a student interest group. Experiment 3 shows that the DTR techn...

Original scientific paper This paper presents coded differential TR (cDTR) receiver that transmits extra bit by mapping information in K different orthogonal codes. The performance of the coded DTR is analyzed and compared with the conventional DTR. Throughout the analysis, the performance of receivers in terms of bit error probability (BEP), data rate and receiver complexity are assessed. The ...

BACKGROUND Although the relation between day-to-day temperature change and coronary heart disease (CHD) mortality is well established, it is unknown whether temperature variation within 1 day, ie, diurnal temperature range (DTR), is an independent risk factor for acute CHD death. METHODS We used time-series and case-crossover approaches to assess the relation between DTR and daily CHD mortali...

When applying a quantile mapping-based bias correction to daily temperature extremes simulated by a global climate model (GCM), the transformed values of maximum and minimum temperatures are changed, and the diurnal temperature range (DTR) can become physically unrealistic. While causes are not thoroughly explored, there is a strong relationship between GCM biases in snow albedo feedback during...

Hybrid wireless networks support both Mobile Adhoc network (MANET) and Infrastructure wireless network. An efficient data routing protocol is important to improve the network efficiency. This efficient data routing protocol support hybrid wireless networks for high capacity and scalability. In this paper, we proposed Distributed Three-Hop Routing (DTR) protocol to improve the capacity of Hybrid...

EFFECT OF A REPEATED BOUT OF ECCENTRICALLY-BIASED CONTRACTIONS ON INSULIN RESISTANCE by Michael S. Green This study determined if insulin resistance (IR), induced by an acute bout of eccentrically-biased contractions that resulted in muscle injury, was attenuated following a repeated bout of contractions. Female subjects (n = 10, age 24.7 ± 3.0 yr, weight 64.9 ± 7.4 kg, height 1.67 ± 0.02 m, bo...

This is a sequel to a study of the empirical estimation of the annual mean temperature and its range, at any location on land, based on the historical surface climate record. Here the spatial patterns of the daily temperature range (DTR) and its seasonal variation are examined. The DTR is highest in the subtropical deserts and is less at high latitudes, as well as within 30–150 km from an ocean...
