Multi-boson Measurements in CMS

Recent results from the CMS experiment on the production of multiple vector bosons in proton-proton collisions at the CERN LHC are presented. Measurements of WZ and ZZ production with fully leptonic decays, Z$(\nu\nu)\gamma$, and WV (V $=$ W,Z $\rightarrow q\bar{q}$) production at 8 and 13 TeV are discussed. Selected cross section measurements, unfolded differential measurements, and limits on anomalous triple gauge couplings are presented and compared with theoretical predictions.Comment: LHCP 2017 Proceedings, CMS CR-2017/36

Cultivating nutrition

"Over the past decade, donor-funded policies and programs designed to address undernutrition in the Global South have shifted away from agriculture-based strategies toward nutrient supplementation and food fortification programs. Given the potential benefits resulting from agriculture-based nutrition interventions, this study uses Q methodology to explore the views of a range of stakeholders from both developed and developing countries on the value of—and constraints related to—gender-sensitive, nutrition-oriented agricultural projects. The three distinct viewpoints that emerge from this exercise all support the use of agricultural strategies to improve nutrition and underline the importance of gender-sensitive approaches. The viewpoints differ, however, on the relative importance of nutrition education, the strategic use of nutrient supplementation and food fortification, and the degree to which agriculture-based approaches have an impact on nutrition. The findings indicate that there is common ground among a range of stakeholders—donors, researchers, policymakers, and program practitioners—on the benefits of agriculture and gender-sensitive strategies to improve nutrition. These areas of agreement can serve as a foundation for forging an effective integrative strategy to improve nutrition that includes gender-sensitive agricultural approaches."

Manure management education and demonstration project

Proper methods and rates for applying livestock manure to crop land are critical to preserve water quality. The growth and concentration of Iowa\u27s swine production facilities in recent years pose environmental concerns in terms of manure application to agricultural land. This project demonstrated a feasible, economical testing program to evaluate the nutrient content of livestock wastes. A portable kit was used that can test for ammonia nitrogen and phosphorus in both liquid and solid manure, facilitating on-site, immediate testing. The results of this on-farm testing kit, which is currently available to producers, were then compared with laboratory analysis to determine the kit\u27s accuracy. By analyzing the nutrient value of manure immediately prior to land application, producers can make more environmentally sound manure management decisions

Calcium and magnesium absorption and retention by growing goats offered diets with different calcium sources

Calcium addition is necessary in order to balance the high phosphorus concentrations that are characteristic of high-concentrate ruminant diets. However, calcium sources differ in their bioavailability. Our objective was to determine apparent calcium and magnesium absorption and retention in goats offered diets containing different sources of calcium. Spanish-Boer goats (n = 18; 19.6 ± 1.88 kg) were stratified by body weight (BW) and sex and randomized to dietary treatments consisting of Purina Antlermax 16 containing either calcium carbonate (CC), Calmin (CM) or Milk Cal (MC). Goats were adapted to a control, corn-based high-concentrate diet on pasture and then moved to individual 1.0 × 1.5-m pens with plastic coated expanded metal floors, and adjusted to their respective diets along with removal of hay from the diet over a 7-d period. Goats were then offered their respective diets at a total of 2% of BW in equal feedings at 8:30 AM and 5:00 PM for an additional 14-d adaption period to diet and facilities followed by a 7-d collection of total urine and feces. Data were analyzed using PROC MIXED of SAS. Calcium and magnesium intake were not different (P ≥ 0.12) among diets. Calcium and magnesium apparent absorption and retention (g/d and % of intake) were greatest (P \u3c 0.05) in goats offered CC and did not differ (P ≥ 0.20) between goats offered the CM and MC diets. Therefore, calcium and magnesium were more available for goats from the diet containing calcium carbonate compared with diets containing Calmin and Milk Cal

Enhanced and reduced atom number fluctuations in a BEC splitter

We measure atom number statistics after splitting a gas of ultracold 87Rb atoms in a purely magnetic double-well potential created on an atom chip. Well below the critical temperature for Bose-Einstein condensation T_c, we observe reduced fluctuations down to -4.9dB below the atom shot noise level. Fluctuations rise to more than +3.8dB close to T_c, before reaching the shot noise level for higher temperatures. We use two-mode and classical field simulations to model these results. This allows us to confirm that the super-shot noise fluctuations directly originate from quantum statistics

Effects of Noisy Oracle on Search Algorithm Complexity

Grover's algorithm provides a quadratic speed-up over classical algorithms for unstructured database or library searches. This paper examines the robustness of Grover's search algorithm to a random phase error in the oracle and analyzes the complexity of the search process as a function of the scaling of the oracle error with database or library size. Both the discrete- and continuous-time implementations of the search algorithm are investigated. It is shown that unless the oracle phase error scales as O(N^(-1/4)), neither the discrete- nor the continuous-time implementation of Grover's algorithm is scalably robust to this error in the absence of error correction.Comment: 16 pages, 4 figures, submitted to Phys.
