Nanosized La 2 O 3: Sm 3+ and La 2 O 3: Sm 3+, Bi 3+ phosphor powders were prepared via combustion synthesis. The structures and morphology were examined using powder X-ray diffraction and transmission electron microscope, respectively. The photoluminescence spectra were investigated at different doping concentrations of Sm 3+ and Bi 3+ ions. The results indicate that La 2 O 3: Sm 3+ ( Bi 3+) exhibited good crystallinity and spherical-like particles. All phosphors give emission bands centered at 564, 608 and 650 nm corresponding to 4 G 5/2→6 H J ( J =5/2, 7/2 and 9/2) transitions of Sm 3+ ions, respectively. Interestingly, the emission intensity of Sm 3+ ions is significantly enhanced with the addition of Bi 3+ ions to La 2 O 3: Sm 3+ and the maximum occurs at a Bi 3+ concentration of 0.8 mol%. The La 2 O 3: Sm 3+, Bi 3+ phosphor with highly enhanced luminescence is very encouraging for applications in display and tunable solid lasers.

Abstract Comparing animal and agronomic performance following renovation of toxic-infected tall fescue (TF) to novel endophyte tall fescue (NE) is fundamental to evaluating economic returns and increasing adoption of NE. In 2018, three NE renovation strategies were implemented in a randomized complete block design in Bahama, NC. Strategies included: 1) control (C), 2) renovation to NE after one season of a single specie cover crop (1-SM), 3) renovation to NE after three seasons of a single specie cover crop (3-SM), and 4) renovation to NE after three seasons of a multi-specie cover crop (3-CM). Sixty-four Angus heifers (initial BW 290 kg ± 88) were randomly assigned to treatments and strip-grazed stockpiled fescue for 56-d, two years after NE establishment. Forage yield and nutritive value was measured every 14-d. Data were analyzed using proc GLIMMIX of SAS v9.4. Average daily gain was greatest (P = 0.0024) for cattle grazing 1-SM (0.67 kg/d), and least for 3-CM (0.54 kg/d) and C (0.44 kg/d), which did not differ. 3-SM (0.57 kg/d) did not differ from other treatments. Within the grazing period, forage yield was greatest (P = 0.0001) in 3-CM, 3-SM, and C compared to 1-SM (3053, 2941, 2856 and 2465 kg/ha, respectively). Prior to the initiation of grazing, crude protein concentration was greater (P = 0.0089) for 3-CM (17.5%) compared to C, 1-SM, and 3-SM (15.8%, 15.8% and 15.3%, respectively). Neutral detergent fiber was greater (P = 0.0135) for 3-SM (57%) than C (55.1%) and 3-CM (54.5%), but did not differ from 1-SM (54.6%). Concentration of total digestible nutrients was greater (P = 0.0187) for 3-CM (73.2%) compared to 1-SM (72.1%) and 3-SM (71.9%), but did not differ from C (72.5%). Data suggest animal and agronomic performance for NE was improved compared to TF during winter stockpile grazing in years following renovation.

Soil moisture (SM) is the primary variable regulating the soil temperature (ST) differences between daytime and night-time, providing protection to crop rooting systems against sharp and sudden changes. It also has a number of practical applications in a range of disciplines. This study presents an approach to incorporating the effect of ST for the accurate estimation of SM using Earth Observation (EO) data from NASA’s SMAP sensor, one of the most sophisticated satellites currently in orbit. Linear regression analysis was carried out between the SMAP-retrieved SM and ground-measured SM. Subsequently, SMAP-derived ST was incorporated with SMAP-derived SM in multiple regression analysis to improve the SM retrieval accuracy. The ability of the proposed method to estimate SM under different seasonal conditions for the year 2016 was evaluated using ground observations from the Wales Soil Moisture Network (WSMN), located in Wales, United Kingdom, as a reference. Results showed reduced retrieval accuracy of SM between the SMAP and ground measurements. The R2 between the SMAP SM and ground-observed data from WSMN was found to be 0.247, 0.183, and 0.490 for annual, growing and non-growing seasons, respectively. The values of RMSE between SMAP SM and WSMN observed SM are reported as 0.080 m3m−3, 0.078 m3m−3 and 0.010 m3m−3, with almost zero bias values for annual, growing and non-growing seasons, respectively. Implementation of the proposed scheme resulted in a noticeable improvement in SSM prediction in both R2 (0.558, 0.440 and 0.613) and RMSE (0.045 m3m−3, 0.041 m3m−3 and 0.007 m3m−3), with almost zero bias values for annual, growing and non-growing seasons, respectively. The proposed algorithm retrieval accuracy was closely matched with the SMAP target accuracy 0.04 m3m−3. In overall, use of the new methodology was found to help reducing the SM difference between SMAP and ground-measured SM, using only satellite data. This can provide important assistance in improving cases where the SMAP product can be used in practical and research applications.

e12020 Background: Secondary malignancies (SM) developing during metastatic breast cancer (MBC) are obviously more complicated for diagnosis, potential surgery and for further MBC treatment. However, the frequency of SM during MBC is not well explored, in contrast to SM after nonmetastatic BC. The aim of this paper is to determine frequency of SM in MBC patients and to determine the percentage of surgically treated SM. Methods: Hospital charts of BC patients were retrospectively analyzed at the Institute for Oncology and Radiology of Serbia. Patients who developed SM at any time point after BC were included in this analysis. Patients with contra-lateral BC and acute leukemia were excluded. Patients with SM during MBC were separately analyzed. Results: A cohort of 50 BC patients with SM was identified. Median age was 50 (range 32–78 years) median time to SM was 65.3 months (range 1–276). Forty-six patients had histological confirmation of SM. In 30 patients SM developed during treatment for MBC. Four SM were not confirmed by biopsy due to SM site or high burden of MBC. Median age was 53.4 years (range 34–74), median time to SM development was 78.9 months, and median time to BC metastases was 60.1 months. The most frequent SM in MBC patient were lung (5), endometrial (4, all treated with tamoxifen), ovarian (3), thyroid (3), cervical (3), and colon carcinoma (2). Only 14 patients with SM (14/30: 46%) could be treated with radical surgery and SM did not influenced further MBC treatment. Conclusions: According to our experience, SM develops more frequently in MBC than in non MBC patients, representing 60% (30/50 patients) of all SM in BC patients; 46.6% (14/30) of SM diagnosed during MBC could be surgically resected, and does not influence further MBC treatment. No significant financial relationships to disclose.

Syringomyelia secondary to Chiari-like malformation (so-called CM-SM syndrome) is a common disorder in Cavalier King Charles Spaniels (CKCS) that is diagnosed using standard structural MRI, though imaging findings often do not correlate with the severity of clinical symptoms. Diffusion tensor imaging (DTI) is a technique that defines subtle microstructural changes in the course of many brain and spinal cord diseases, that are not visible on standard MRI. The aim of the study was to identify the correlation between the presence of clinical symptoms and DTI parameters, such as apparent diffusion coefficient (ADC) and fractional anisotropy (FA) within the spinal cord in the course of CM-SM. Study subjects included 18 dogs, CKCS with MRI-confirmed SM (SM group), and 12 CKCS dogs without SM (non-SM group). The SM group was divided into SM-symptomatic group (n = 8) and SM-asymptomatic group, n = 10). All dogs underwent same clinical and neurological assessment followed by MRI examination. All MRI studies were performed on a 1.5T MRI scanner. The MRI spine protocol included: transverse and sagittal T2-weighted images followed by DTI performed in the sagittal plane. The measurements of FA and ADC values were performed manually using the region of interest (ROI) method at the level of three intervertebral discs between C1 and C4. Notable differences in age and body weight were found. No significant differences in FA and ADC values between the SM and non-SM groups were found, but between non-SM, SM-asymptomatic and SM-symptomatic groups significant differences were found in ADC values in all three ROIs and in FA values in ROI-1 and ROI-3. SM-symptomatic dogs compared to non-SM, showed decreased FA value in ROI-1 and ROI-3 also increased ADC value in ROI-1, ROI-2 and ROI-3. SM-symptomatic dogs compared to SM-asymptomatic showed also decreased FA value in ROI-1 and ROI-3, and also increased ADC value in ROI-1, ROI-2 and ROI-3. The results suggest that the values of DTI parameters correlate with the severity of clinical symptoms in the course of CM-SM in animals. The use of DTI evaluation of CM-SM patients carries a potential value as a clinically relevant protocol for an objective assessment of the spinal cord.

Multiferroic Bi 1-x Sm x FeO 3(x = 0.00, 0.05, 0.1, 0.15, 0.2) ceramics were prepared by conventional solid state reaction method. X-ray diffraction measurement was carried out to characterize the crystal structure and to detect the impurities existing in these ceramics. The substitution of rare earth Sm for Bi was found to decrease the impurity phase in BiFeO 3 ceramics. There is strong evidence that both lattice constants a and c of the unit cell become smaller as the Sm 3+ content is increased. The effect of introducing Sm 3+ is shown to decrease the optical band gap for doped sample Bi 1-x Sm x FeO 3. Additionally, the temperature-dependent Raman measurement performed for the lattice dynamics study of Bi 1-x Sm x FeO 3 samples reveals a strong band centered at around 1000–1300 cm-1 which is associated with the resonant enhancement of two-phonon Raman scattering in the multiferroic Bi 1-x Sm x FeO 3 samples. This two-phonon signal is shown to broaden with increasing x. The Raman spectra at low wavenumbers are suggested to be related with magnon in this system.

Abstract Renovating toxic-infected tall fescue (Lolium arundinaceum) (TF) pastures to novel endophyte tall fescue (NE) is a solution to mitigate the negative associated effects of toxic fescue in beef cattle. However, beef cattle producers are uncertain of the payback period for costs associated with renovation techniques in terms of farm profitability and agronomic performance. In 2018, three renovation strategies were implemented in a randomized complete block design in Bahama, NC. Strategies included: 1) control (C), 2) renovation to NE after one season of a single specie cover crop (1-SM), 3) renovation to NE after three seasons of a single specie cover crop (3-SM), and 4) renovation to NE after three seasons of a multi-specie cover crop (3-CM). Each treatment plot (0.81 ha) was evaluated for botanical composition and hay was harvested in May and August of 2020. Round bales from each treatment were weighed to determine yield and core sampled to determine nutritive value. Data were analyzed using proc GLIMMIX of SAS v9.4. Combined forage yield was greater (P = 0.0226) for 3-CM (8,816 kg/ha) compared to 3-SM (7,191 kg/ha) and C (6,920 kg/ha), but did not differ from 1-SM (7,775 kg/ha). Crude protein concentration was greater (P = 0.035) for C (10.2%) in comparison to 3-SM (9.35%) in harvest 1, but was not different (P = 0.93) in harvest 2. Percentage of fescue in the sward was greatest (P = 0.0002) for 3-SM and least for C (84.9 and 62%, respectively). Similarly, presence of undesirable plants was greater (P < 0.0001) for C (37.5%) than 1-SM, 3-CM and 3-SM (23.7, 15.2 and 12.7%, respectively). Percentage of bare ground did not differ among treatments (P = 0.31). Data suggest agronomic performance for 3-CM and 3-SM was improved compared to C in years following pasture renovation.

Abstract The objective of this study was to analyze animal performance following renovation of toxic-infected tall fescue (TF) to novel endophyte tall fescue (NE) in order to increase producer adoption of NE. In 2018, three renovation strategies were implemented in a randomized complete block design. Strategies included: 1) control (C), 2) renovation to NE after one season of a single-specie cover crop (1-SM), 3) renovation to NE after three seasons of a single-specie cover crop (3-SM), and 4) renovation to NE after three seasons of a multi-specie cover crop (3-CM). Forty-eight pregnant (30-90-d) Angus heifers (initial BW 383 kg ± 32) were randomly assigned to rotationally graze spring growth for 56-d, two years after NE establishment. Pre- and post-grazing forage mass was measured every 7-d. Animal measurements were collected every 14-d. Data were analyzed using procGLIMMIX of SASv9.4. Average daily gain was greatest (P < 0.0001) for cattle grazing 3-CM (0.74 kg/d), 1-SM (0.72 kg/d), and 3-SM (0.62 kg/d) and least for C (0.33 kg/d). Pre-grazing forage biomass was greatest (P = 0.0157) in 3-CM (3261 kg/ha) and lowest in C (2523 kg/ha), with 3-SM (2813 kg/ha) and 1-SM (2779 kg/ha) being intermediate. Post-grazing forage biomass was greatest (P = 0.0063) in 3-CM (1982 kg/ha), C (1916 kg/ha), 1-SM (1900 kg/ha), but lower in 3-SM (1592 kg/ha). Prior to grazing, body condition score (BCS) was higher (P = 0.0029) for animals grazing C (5.48), but change in BCS of animals within treatments was not different (P = 0.798). Hair shedding scores (HS) were not different on d-0, with all treatments near 5. However, HS were highest (P < 0.0001) in C (4.75), and lowest in 1-SM (1.75), 3-SM (2), and 3-CM (2) after 56-d. Data suggest animal performance for NE was improved compared to TF during spring grazing in years following renovation.

In spatial modulation (SM), a single signal symbol is transmitted from a given physical antenna, where both the signal symbol and the antenna index carry information. SM with multiple active antennas (MA-SM) transmits several signal symbols from a combination of antennas at each channel use, thereby increasing the spectral efficiency. MA-SM is proposed in combination with a new 3-dimensional constellation, where signal symbols transmitted from a given antenna combination are rotated before transmission. In this paper, we derived an upper-bound on the error probability of the MA-SM as a function of the rotation angles. The search for the optimal rotation angles is modeled as a multi-objective optimization problem. We concluded based on both analytical and simulation results that the 3-dimensional constellation with the optimal angles achieved negligible improvement. Therefore, we do not recommend using the 3-dimensional constellation with the MA-SM system.

In recent decades, microwave remote sensing (RS) has been used to measure soil moisture (SM). Long-term and large-scale RS SM datasets derived from various microwave sensors have been used in environmental fields. Understanding the accuracies of RS SM products is essential for their proper applications. However, due to the mismatched spatial scale between the ground-based and RS observations, the truth at the pixel scale may not be accurately represented by ground-based observations, especially when the spatial density of in situ measurements is low. Because ground-based observations are often sparsely distributed, temporal upscaling was adopted to transform a few in situ measurements into SM values at a pixel scale of 1 km by introducing the temperature vegetation dryness index (TVDI) related to SM. The upscaled SM showed high consistency with in situ SM observations and could accurately capture rainfall events. The upscaled SM was considered as the reference data to evaluate RS SM products at different spatial scales. In regard to the validation results, in addition to the correlation coefficient (R) of the Soil Moisture Active Passive (SMAP) SM being slightly lower than that of the Climate Change Initiative (CCI) SM, SMAP had the best performance in terms of the root-mean-square error (RMSE), unbiased RMSE and bias, followed by the CCI. The Soil Moisture and Ocean Salinity (SMOS) products were in worse agreement with the upscaled SM and were inferior to the R value of the X-band SM of the Advanced Microwave Scanning Radiometer 2 (AMSR2). In conclusion, in the study area, the SMAP and CCI SM are more reliable, although both products were underestimated by 0.060 cm3 cm−3 and 0.077 cm3 cm−3, respectively. If the biases are corrected, then the improved SMAP with an RMSE of 0.043 cm3 cm−3 and the CCI with an RMSE of 0.039 cm3 cm−3 will hopefully reach the application requirement for an accuracy with an RMSE less than 0.040 cm3 cm−3.

Abstract Renovating toxic-infected tall fescue (TF) pastures to non-toxic infected tall fescue (NE) for profitability, animal and agronomic performance without compromising soil health is needed to transition to NE in the southeast U.S. Three renovation strategies were evaluated for impact on soil health, profitability, and animal and agronomic performance in a replicated field trial located in Bahama, NC. Strategies included: 1) control (C), 2) renovation to NE after one season of a single specie cover crop (1-SM), 3) renovation to NE after three seasons of a single specie cover crop (3-SM), and 4) renovation to NE after three seasons of a multi-specie cover crop (3-CM). Soil samples were taken prior to renovation to establish baseline soil health measurements for each strategy. Data were analyzed using proc GLM of SAS v9.4. Thirty-two Angus and Angus cross steers (initial BW 425 ± 27) were blocked by BW and randomly assigned to one of four treatments during the first season of renovation. Average daily gain for cattle grazing the first season of cover crops was greatest (P < 0.001) with 3-CM (0.8 kg/d), 3-SM (0.8 kg/d), in comparison to C and 1-SM (-0.1 kg/d). Gain per hectare differed among treatments (P < 0.001) with 3-SM and 3-CM being greater than C and 1-SM (179, 154, -24, -43 kg/ha, respectively). Within the two-month grazing period, yield different during the month of August (P < 0.001), with 3-SM being the highest (4511 kg/ha) in comparison to 3-CM (3275 kg/ha), 1-SM (2922 kg/ha), and C (2644 kg/ha), while yield was highest (P <0.001) for 3-CM in September (2931 kg/ha) in comparison to all other treatments. Data suggest agronomic and animal performance for 3-CM and 3-SM were improved compared to C and could partially alleviate initial renovation costs.

Abstract. Providing accurate soil moisture (SM) conditions is a critical step in model initialization in weather forecasting, agricultural planning, and water resources management. This study develops monthly-to-seasonal (M2S) top layer SM forecasts by forcing 1- to 3-month-ahead precipitation forecasts with Noah3.2 Land Surface Model. The SM forecasts are developed over the southeastern US (SEUS), and the SM forecasting skill is evaluated in comparison with the remotely sensed SM observations collected by the Soil Moisture Active Passive (SMAP) satellite. Our results indicate potential in developing real-time SM forecasts. The retrospective 18-month (April 2015–September 2016) comparison between SM forecasts and the SMAP observations shows statistically significant correlations of 0.62, 0.57, and 0.58 over 1-, 2-, and 3-month lead times respectively.
