1Current Status and Future Challenges of Weather Radar Polarimetry: Bridging the Gap between Radar Meteorology/Hydrology/Engineering and Numerical Weather Prediction显示文摘After decades of research and development, the WSR-88 D(NEXRAD) network in the United States was upgraded with dual-polarization capability, providing polarimetric radar data(PRD) that have the potential to improve weather observations,quantification, forecasting, and warnings. The weather radar networks in China and other countries are also being upgraded with dual-polarization capability. Now, with radar polarimetry technology having matured, and PRD available both nationally and globally, it is important to understand the current status and future challenges and opportunities. The potential impact of PRD has been limited by their oftentimes subjective and empirical use. More importantly, the community has not begun to regularly derive from PRD the state parameters, such as water mixing ratios and number concentrations, used in numerical weather prediction(NWP) models.In this review, we summarize the current status of weather radar polarimetry, discuss the issues and limitations of PRD usage, and explore potential approaches to more efficiently use PRD for quantitative precipitation estimation and forecasting based on statistical retrieval with physical constraints where prior information is used and observation error is included. This approach aligns the observation-based retrievals favored by the radar meteorology community with the model-based analysis of the NWP community. We also examine the challenges and opportunities of polarimetric phased array radar research and development for future weather observation.Guifu ZHANG Vivek N.MAHALE Bryan J.PUTNAM Youcun QI Qing CAO ANDrew D.BYRD Petar BUKOVCIC Dusan S.ZRNIC Jidong GAO Ming XUE Youngsun JUNG Heather D.REEVES Pamela L.HEINSELMAN AlexANDer RYZHKOV Robert D.PALMER Pengfei ZHANG Mark WEBER Greg M.MCFARQUHAR Berrien MOORE III Yan ZHANG Jian ZHANG J.VIVEKANANDAN Yasser AL-RASHID Richard L.ICE Daniel S.BERKOWITZ Chong-chi TONG Caleb FULTON Richard J.DOVIAK 2019Advances in Atmospheric Sciences2019,36,6:9

3Local Variability in Temperature, Humidity and Radiation in the BaekduDaegan Mountain Protected Area of Korea显示文摘A novel embedded sensor network records changes in key climatic-environmental variables over a range of altitude in the BaekduDaegan Mountain (BDM) of Gangwon Province in Korea, a protected mountain region with unique biodiversity undergoing climate change research. The investigated area is subdivided into three horizontal north-south study areas. Three variables, temperature (T, ℃), relative humidity (RH, %), and light intensity (LI, lumens m -2 , or lux, lx), have been continuously measured at hourly intervals from June, 2010 to September, 2011 using HOBO H8 devices at 10 fixed study sites. These hourly observations are aggregated to monthly, seasonal and annual mean values, and results are summarized to inaugurate a long-term climate change investigation. A region wide T difference in accordance with altitude, or lapse rate, over the interval is calculated as 0.4℃100 m -1 . T lapse rates change seasonally, with winter lapse rates being greater than those of summer. RH is elevated in summer compared to other seasons. LI within forestland is lower during summer and higher during other seasons. The obtained results could closely relate to the vegetation type and structure and the terrain state since data loggers were located in forestland.CHAE Heemun LEE Hyunju LEE Sangsin CHEONG Yukyong UM Gijeung MARK Bryan PATRICK Nathan 2012Journal of Mountain Science2012,9,5:5

5Characteristics of Clostridium difficile infection in patients hospitalized with myelodysplastic syndrome or acute myelogenous leukemia显示文摘AIM To evaluate factors associated with Clostridium difficile infection (CDI) and outcomes of CDI in the myelodysplastic syndrome(MDS) and acute myeloid leukemia (AML) population.METHODS After IRB approval,all MDS/AML patients hospitalized at the University of Maryland Greenebaum Comprehensive Cancer Center between August 2011 and December 2013 were identified.Medical charts were reviewed for demographics,clinical information,development of CDI,complications of CDI,and mortality.Patients with CDI,defined as having a positive stool PCR done for clinical suspicion of CDI,were compared to those without CDI in order to identify predictors of disease.A t-test was used for comparison of continuous variables and chisquare or Fisher's exact tests were used for categorical variables,as appropriate.RESULTS Two hundred and twenty-three patients (60.1% male,mean age 61.3 years,13% MDS,87% AML) had 594 unique hospitalizations during the study period.Thirtyfour patients (15.2%) were diagnosed with CDI.Factors significantly associated with CDI included lower albumin at time of hospitalization (P < 0.0001),prior diagnosis of CDI (P < 0.0001),receipt of cytarabine-based chemotherapy (P = 0.015),total days of neutropenia (P = 0.014),and total days of hospitalization (P = 0.005).Gender (P = 0.10),age (P = 0.77),proton-pump inhibitor use (P = 0.73),receipt of antibiotics (P = 0.66),and receipt of DNA hypomethylating agent-based chemotherapy (P = 0.92) were not significantly associated with CDI.CONCLUSION CDI is common in the MDS/AML population.Factors significantly associated with CDI in this population include low albumin,prior CDI,use of cytarabine-based chemotherapy,and prolonged neutropenia.In this study,we have identified a subset of patients in which prophylaxis studies could be targeted.Kamini Shah Bryan F Curtin Christopher Chu Daniel Hwang Mark H Flasar Erik von Rosenvinge 2017World Journal of Clinical Oncology2017,8,5:3
6Agricultural water conservation in China:plastic mulch and traditional irrigation显示文摘Plastic mulch is commonly used with micro-irrigation in developed countries;however,Chinese farmers use plastic mulch on a vast scale independent of micro-irrigation.For the past three decades,China’s land area in plastic mulch has exceeded the world’s total land area in micro-irrigation.We report results from the water-scarce region of Minqin County,where 87%of Chinese farmers interviewed responded that they use plastic mulch to conserve water and 53%to increase yields.Survey results indicated the desire to conserve water through the use of plastic mulch to be statistically equivalent to the desire to increase yields.Responses to interviews and surveys indicate that farmers perceive water savings of 24-26%when plastic mulch is used.Interview and survey responses suggest farming families are shifting to purchasing wheat from outside the region;a potential import of'virtual water'into this water-scarce region.Mark Ingman Mary V.Santelmann Bryan Tilt 2015Ecosystem Health and Sustainability2015,1,4:3

8Pharmacological management of behavioral symptoms associated with dementia显示文摘Dementia is a clinical syndrome with features of neurocognitive decline. Subtypes of dementia include Alzheimer's, frontotemporal, Parkinson's, Lewy body disease, and vascular type. Dementia is associated with a variety of neuropsychiatric symptoms that may include agitation, psychosis, depression, and apathy. These symptoms can lead to dangerousness to self or others and are the main source for caregiver burnout. Treatment of these symptoms consists of nonpharmacological and pharmacological interventions. However, there are no Food and Drug Administration-approved medications for the treatment of behavioral and psychological symptoms of dementia. Pharmacological interventions are used off-label. This article reviews the current evidence supporting or negating the use of psychotropic medications along with safety concerns, monitoring, regulations, and recommendations.Subramoniam Madhusoodanan Mark Bryan Ting 2014World Journal of Psychiatry2014,4,4:2
