Wacana Kontroversi Agama di Malaysia: Satu Kajian Terhadap Pelaporan Akhbar Utusan Malaysia dan The Star Mengenai Tuntutan COMANGO
Authors: Mohd Sofian Muhammad Raqib , Azmawati Azman Azwan
Published: January 2021

Negara Malaysia sebelum ini telah mengalami pelbagai insiden dan isu yang melibatkan kaum dan agama sehingga telah mendatangkan masalah dari segi perhubungan antara kaum dan agama. Isu-isu yang melibatkan agama dan kaum ini sering kali melibatkan agama Islam, yang juga adalah agama rasmi negara Malaysia. Agama Islam sering kali menjadi subjek yang sensitif kerana ia sering kali dijadikan sebagai alat untuk mengekalkan hegemoni dan status quo oleh pihak kerajaan dalam konteks di Malaysia. Pada tahun 2013, sebuah pertubuhan NGO yang dikenali sebagai COMANGO telah menghantar beberapa tuntutan yang melibatkan hak asasi manusia di Malaysia kepada Pertubuhan Bangsa-bangsa Bersatu (PBB) di Penilaian Berkala Sejagat (UPR). COMANGO telah dikatakan telah membuat beberapa tuntutan yang mencabar kedudukan Islam dan Melayu di Malaysia dan mempromosi seks bebas. Isu ini telah mendapat liputan yang meluas di media akhbar di Malaysia khususnya akhbar arus perdana di Malaysia dan ia dilihat sebagai sebuah isu yang boleh mendatangkan manfaat kepada pihak kerajaan untuk mengukuhkan kuasa mereka dengan memainkan isu ini kepada khalayak umum. Oleh itu, artikel ini bertujuan untuk mengkaji mesej-mesej yang disampaikan oleh akhbar arus perdana mengenai isu ini, iaitu akhbar Utusan Malaysia dan The Star. Dapatan kajian menunjukkan kedua-dua akhbar yang dikaji memberikan liputan yang hampir sama dengan sedikit kelainan. Akhbar Utusan Malaysia dilihat sangat menentang tuntutan COMANGO tersebut dan mengangkat parti UMNO sebagai parti yang memperjuangkan Islam manakala akhbar The Star walaupun dilihat lebih banyak memberikan peluang kepada pihak COMANGO untuk menyatakan pendirian mereka, namun dilihat masih berhati-hati dalam pelaporan mereka mengenai isu tersebut.

Affirmative Action Model in Strengthening the Education Rights Protection and Fulfillment of Person with Disability
Authors: Mohamad Irwansyah Reza , Hadi Ismet
Published: January 2021

The uncertainty of legal regulations on the fulfillment of education rights for persons with disabilities creates serious problems. The absence of special arrangements causes overlapping responsibilities which will result in not being integrated into programs that support the educational needs of persons with disabilities. This problem requires the seriousness of local governments to provide protection and fulfillment of education rights for persons with disabilities. This study aims to determine the legal policy for the Protection and Fulfillment of the Right to Education and to formulate an affirmative action model for the protection and fulfillment of the education rights of persons with disabilities in the future. This study uses empirical legal research, namely research that initially examines secondary data, then continues with research on primary data through interview data collection. The results of the research show that local governments still seem to have not fully provided protection and fulfillment of the rights of persons with disabilities to adequate education so that they face various kinds of discrimination, even though there are regulations at the level of the 1945 Constitution of the Republic of Indonesia and laws that have guaranteed it. Second, regulations at the level of Regional Regulations in Gorontalo Province have not reached the lateness of fulfilling the right to education both inclusively and specifically in a systematic and comprehensive manner. It is necessary to have a legal reform in the form of affirmative policies in the field of education for persons with disabilities.

We present observational results of variations in the ionospheric parameters hmF2 and NmF2 over the Ukrainian Antarctic station “Akademik Vernadsky” for magnetically quiet conditions. The results of comparative analysis of observational data and the International Reference Ionosphere-2016 model predictions are presented. The main objective of this study is to investigate the temporal variations of two key ionospheric parameters – the F2 layer peak height and electron density – during very quiet space weather conditions using data of vertical sounding of the ionosphere obtained over the Ukrainian Antarctic station “Akademik Vernadsky” and comparison the observation results with model values. Methods: The temporal variations of the F2 layer peak height and electron density were calculated from ionograms obtained with ionosonde installed at the Ukrainian Antarctic station “Akademik Vernadsky” with subsequent electron density profile inversion. Diurnal variations of hmF2 and NmF2 were calculated using a set of sub-models of the IRI-2016 model for comparison with results of observational studies. Results: We found that for the Antarctic region option of IRI-2016 model for the F2 layer peak height SHU-2015 provides a better fit for hmF2 through the investigated period compare to the AMTB-2013 model predictions. Electron density models (URSI, CCIR) generally well reproduce the observed variations of NmF2 during periods of absence non-standard manifestations of space weather, which are possible for quiet conditions too. Hypotheses regarding the possible reasons for experimental and model differences in variations of NmF2 are discussed. The analysis of effect of geomagnetic storm on September 24, 2020 on NmF2 variations was carried out. Conclusions: The obtained results demonstrate peculiarities of the state of the ionosphere-plasmasphere system over Antarctica under very quiet space weather conditions and provide evaluation of predictive capabilities of modern international reference ionosphere models. New knowledge about the features of electron density variations in the ionosphere for magnetically quiet conditions over the Antarctic region has practical value for specialists which are engaged in the study of the near-Earth space environment, in particular, at high latitudes, and also work on correction of global ionospheric models.

Authors: GUPTA ANUBHAV , S PRAVEEN , KUMAR ABHISHEK , SHREE PRIYANKA , MISHRA SUCHANA
Published: January 2021

Organic solar cells using P3HT: PCBM as an active layer on ITO coated glass substrates were fabricated and characterized. Different air annealing procedures and cathode materials were tried and the characteristics were compared with that of a standard thin film polycrystalline silicon solar cell. It was found that the sample prepared with post-deposition air annealing at 130 oC improves the open circuit voltage (Voc) considerably. Besides, short circuit current (Isc) and the efficiency (η) were highest for the sample with a non annealed active layer. Series resistance (Rs) for this sample was lowest, but 103 times higher than that of the silicon solar cell, which in turn may have reduced the efficiency value for the organic cell compared to silicon.

Comparative Study of PID Based VMC and Fuzzy Logic Controllers for Flyback Converter
Authors: Kumar P. Rajesh , Kumar S. L. V. Sravan
Published: January 2021

In this paper performance of flyback converter by using PID controller and Fuzzy controller are studied, compared and analyzed. The above study is done for 200W, 230V A.C input 48V DC output. Design of fuzzy controller is based on the heuristic knowledge of converter behaviour, and tuning of fuzzy inference requires some expertise to minimize unproductive trial and error. The design of PID control is based on the frequency response of the converter. For the DC-DC converters, the performance of the fuzzy controller was superior in some respects to that of the PID controller. The fuzzy controller is easily to develop, they cover a wide range of operating conditions, and they are more readily customizable in natural language terms. Simulation is done in Matlab environment to show the performance variations of above mentioned converters using both Fuzzy & PID controllers.
Inter-observer Variation of the Alberta Stoke Program Early CT Score (ASPECTS) among Radiologists in the Philippine General Hospital
Authors: Urgel Ryan Jason DL. , Camacho Alvin C.
Published: January 2021

Objective. To determine the inter-observer variation of ASPECTS among radiologists in the Philippine General Hospital (PGH), particularly between trainee radiologists and an expert reader.

Methods. Thirty (30) cranial CT scan studies of clinically-diagnosed, non-hemorrhagic stroke patients were analyzed by 9 trainee radiologists (3 fellows, and 3 senior and 3 junior residents) and one expert reader. Data analysis involved determining the levels of agreement within and across groups, and against the expert reader.

Results and Conclusion. There was moderate agreement (kappa = 0.60) between the junior residents and the expert reader, and substantial agreement between the senior residents and the expert reader (kappa = 0.70), as well as between the fellows and the expert reader (kappa = 0.63). Over-all, there was substantial agreement between the trainee radiologists and the expert reader (kappa = 0.63). It can be concluded that the interpretation of trainee radiologists in PGH, particularly that of a senior resident or a fellow, is comparable with that of an expert reader, and can, thus, be useful in cases where an interpretation of a CT scan procedure in a clinically-diagnosed stroke patient is needed.

Authors: Arcinue Jasson Louie R. , Wang Edward H.M. , Azores Gregorio Marcelo S.
Published: January 2021

Osteosarcoma in pediatric patients has traditionally been treated with amputation, especially if there is a pathologic fracture through the tumor.We report the case of a 12-year-old boy who sustained a pathologic fracture through distal femoral osteosarcoma. After neoadjuvant chemotherapy, he underwent limb saving surgery: wide excision of the osteosarcoma followed by a second-stage reconstruction with an expandable tumor endoprosthesis. He has a functional score of 93% and is free of disease 8 years since diagnosis and 2 years since the end of lengthening.This is the first reported case in Philippine medical literature of limb saving surgery in osteosarcoma reconstructed with an expandable endoprosthesis.

Authors: Flores-Genuino Rowena Natividad S. , Dofitas Belen L. , Dans Leonila F. , Amarillo Ma. Lourdes E.
Published: January 2021

Background. Oral azole drugs are a second-line option for the treatment of pityriasis versicolor but evidence on their efficacy and safety is unclear.

Objectives. To determine the efficacy and safety of oral azoles in the treatment of patients with pityriasis versicolor. Methods: We searched MEDLINE, CENTRAL, EMBASE, LILACS, and HERDIN, from inception to the period between January to February 2014. We did not restrict the search by language or publication status.We included randomized controlled trials (RCTs) that compared the efficacy of oral azoles with placebo or no treatment, with topical agents, other oral azoles or dosing regimens in the treatment of pityriasis versicolor, and that measured any of the pre-specified outcomes (mycologic cure, clinical cure, recurrence, duration to cure, timeto-cure, and quality of life). For adverse effects, we also included non-randomized studies (NRS). We used Cochrane methods to select studies, extract data, assess risk of bias, pool studies, and calculate for treatment effects.

Results. We included 38 RCTs (n=2894) and 56 NRS (n=3452). Overall, there were few pooled studies and evidence was low to moderate quality. Oral azoles were more effective than placebo (mycologic cure, RR 11.34, 95% CI 4.90, 26.28; 3 RCTs, n=131; I2=0%; low quality of evidence) and as effective as topical agents (mycologic cure, RR 1.02, 95% CI 0.86, 1.21; 4 RCTs, n=232; I2=60%; moderate quality of evidence).There were few adverse effects and were mostly minor and transient.

Conclusions. Oral azoles may be more effective than placebo, and are probably as effective as topical agents in the treatment of PV. Triazoles are probably as effective as ketoconazole. Adverse effects were few, mostly minor, and transient.

Published: January 2021

Objective. This study reviewed the current health research and development environment in the Philippines with respect to the engagement between the public and private sectors. The overall objective was to identify the role of the private sector in health research and identify barriers and opportunities for successful public-private health research partnerships.

Methods. Key informant interviews were conducted using a semi-structured interview tool. Secondary data such as annual reports and project funding documents from the Philippine Council for Health Research and Development were also analyzed.

Results. The roles of the private sector when engaging with the public sector for research and development were identified as generators, funders, and adopters of research. Information gathered showed that there were several institutional and practice barriers to the successful collaboration of the public and private sectors, however there were also lessons learned from the successes of cases such as the Axis-Knee System, Sambong, and Lagundi technologies.

Conclusion. The collaboration and partnership of the public and private sectors can be mutually beneficial. Government initiative to increase the ease of collaboration with the private sector in health research was found to be a necessary step to stimulate a productive health research environment.

Understanding Public Willingness to Participate in Local Conservation Initiatives of Urban Trees in Benin City, Nigeria
Authors: Arabomen O. , Chirwa P.W. , Babalola F.D.
Published: January 2021

As global populations become increasingly urban, public participation has emerged as a new and more direct initiative for the conservation of urban trees and ecosystem services (ES). However, little effort has been made to understand the willingness of residents to participate in conservation programs for trees and ES in Benin City, Nigeria. To fill this gap, a survey to understand residents’ knowledge of ES and their perceptions around ES conservation, i.e., personal willingness to participate in voluntary conservation initiatives (VCIs), was conducted. Unlike the general misconception that trees are not appreciated in African cities, this study showed that most residents had a positive appreciation for the ES provided by urban trees in Benin City. Additionally, irrespective of respondents’ demographics, the findings from this study indicated a growing importance of the ES that trees provide, such as regulation of excess heat, scenic beauty, flooding and erosion control, and provision of shade. Hence, willingness to participate in VCIs was related to the growing importance of ES in the study area. Respondents’ knowledge of ES, education, and years of residency increased the probability of an individual’s participation in VCIs in the city. Other sociodemographic factors commonly related to urban forest participation (e.g., gender, marital status, income, profession, and residential location) did not significantly influence the willingness to participate in the conservation programs. Findings from this seminal study could assist future planning and emphasize to city developers, government (at all levels), resource managers, and decision makers the need to consider public values and perceptions towards enhancing conservation initiatives for urban trees in Benin City.
Another Look at Systemic Neonicotinoid Applications for Emerald Ash Borer Suppression
Authors: Olson David , Townsend Lee , Roemmele Eric , Rieske Lynne
Published: January 2021

Emerald ash borer (EAB, Agrilus planipennis) is an invasive phloem feeder from East Asia that has killed millions of ash trees in North America. Currently, effective options for individual tree protection are limited to systemic insecticides, in particular neonicotinoids, which have come under increased scrutiny for their nontarget effects. In this study, green ash (Fraxinus pennsylvanica) trees were treated with two neonicotinoid insecticides, imidacloprid and dinotefuran, at full and half label rates based on trunk diameter to evaluate residues and efficacy. Analyzing the leaf, stem, and root tissues, there was no difference in insecticide residues between application rates within each tissue type. However, there were significantly higher residues of imidacloprid in root tissue compared to other plant tissues, and dinotefuran applied at the full label rate resulted in lower residues in stem phloem tissue. Additionally, insecticide-treated stems were artificially infested with EAB eggs to measure larval success (survival and growth). EAB larvae consumed less phloem in treated trees compared to untreated controls. These findings suggest that, in small-diameter ash, lower than label-recommended doses may be a viable component of an integrated management plan for EAB.
How Tree Risk Assessment Methods Work: Sensitivity Analyses of Sixteen Methods Reveal the Value of Quantification and the Impact of Inputs on Risk Ratings
Authors: Norris M.B. , Moore G.M.
Published: January 2021

Sixteen tree risk assessment methods were subjected to sensitivity analysis to determine which factors most influenced the output of each method. The analyses indicate the relative influence that the input variables exert on the final risk value. Excel was used to create a simple ± 25% or ± 1 rank change (depending on the method) for each criterion, with the change to the output recorded as a percentage. Palisade’s @Risk software was used to undertake a Monte Carlo (with Latin Hypercube sampling) simulation of 5000 iterations based on the input variables and output formula. From the simulation, multivariate stepwise regression was undertaken to determine the influence of each method’s input variables in determining the output values. Results from the sensitivity analysis indicate some clear and strong differences amongst the 16 methods, reflecting that the underlying mathematics, input categories, ranges, and scaling influence the way that different methods process and express risk. It is not surprising that methods perform differently in different circumstances and express risk level differently. The analyses demonstrated that most methods placed too great an emphasis on limited aspects of risk assessment. Most methods strongly focused on the hazard or defect aspects of assessment and the likelihood of failure rather than the consequence aspect of an assessment. While methods were uniquely different, they could be placed into 3 broad groups: Group 1 methods produced a normal distribution with most values around the mean; Group 2 methods produced outputs at the lower end of the risk scale; and Group 3 methods produced outputs evenly if not continuously across the risk scale. Users of tree risk assessment should understand the strengths and weaknesses of any method used, as it could be relatively simple to challenge the results of a risk assessment based on limitations inherent in the underlying methodology.
ESCOLHAS LEXICAIS NO PROCESSO DE TRADUÇÃO DO PORTUGUÊS ESCRITO PARA A LÍNGUA DE SINAIS
Authors: STREIECHEN Eliziane Manosso , OLIVEIRA Josiane De Jesus
Published: January 2021

O presente ensaio tem como objetivo analisar as escolhas lexicais e estratégias adotadas para traduzir um texto escrito na Língua Portuguesa (LP) para a Língua Brasileira de Sinais (Libras). Trata-se de uma pesquisa qualitativa de caráter exploratório, a qual consiste na análise do corpus – vídeo, levantamento de dados por meio de pesquisas sobre a área de tradução, análise textual e análise comentada. Os resultados revelam que, ao realizar a tradução da língua escrita para a língua de sinais, poderemos nos deparar com diversos entraves, uma vez que nem todas as palavras da LP possuem um sinal representativo na Libras. Isso requer certas facetas que o permitam traduzir tais vocabulários.  Por outro lado, é possível conhecer novos conceitos e ampliar o repertório lexical ao se debruçar na busca por sinais e estratégias que aproximem ao máximo possível a tradução do texto escrito, em LP, para a Libras.

Published: January 2021

O presente artigo tem o objetivo de refletir a respeito das diásporas modernas e das múltiplas identidades que advém destes movimentos migrantes, que caracterizam o contexto da globalização e da pós-modernidade. Objetiva-se também explanar algumas das consequências e dos impactos sociais causados pelo Imperialismo, que reverberam ainda na atualidade. Para isto, pretende-se analisar, sob o viés da multiculturalidade e dos distúrbios identitários causados pelos movimentos diaspóricos, a obra literária Americanah, escrita pela autora nigeriana Chimamanda Ngozi Adichie. Através da narrativa e da fundamentação teórica constituída por autores como Stuart Hall, Homi Bhabha, Kabengele Munanga, Kwame Anthony Appiah e Michel Agier, espera-se demonstrar a maneira como as migrações em massa resultam na formação de indivíduos culturalmente híbridos, o que os leva, por vezes, a experienciar sensações de não-pertencimento e conflitos internos acerca da própria identidade.REFERÊNCIAS:ADICHIE, C.

Published: January 2021

Kemudahan teknologi informasi saat ini telah menjadi sebuah kebutuhan primer bagi tiap individu dalam menjalankan aktivitas sehari-hari mulai dari perangkat pendukung dalam aktivitas utama hingga sebagai pendukung dalam kegiatan lainnya. Sistem administrasi di wilayah pinggiran Indonesia – khususnya Kabupaten Bireuen, Nanggroe Aceh – masih dilakukan dengan sistem konvensional. Sistem administrasi di tingkat desa merupakan level terendah dari sistem administrasi ketatanegaraan republik Indonesia, di antaranya pengelolaan data kependudukan, merupakan sebuah sistem administrasi yang melibatkan seluruh lapisan masyarakat, dan juga sebuah hal wajib bagi setiap penduduk Indonesia untuk mengikuti dan terlibat di dalamnya. Pada saat tulisan ini dibuat, sistem administrasi berbasis teknologi informasi di tingkat desa tidak disediakan oleh pemerintah sehingga setiap desa memiliki cara masing-masing dalam menjalankan sistem dan mengelola data kependudukan. Dalam penelitian ini dibahas mekanisme sistem baru berbasis Online, di antaranya rancangan model, alur sistem hingga kebutuhan sistem secara umum. Penggunaan media internet dalam pelaksanaan kegiatan administrasi tidaklah sepenuhnya berjalan sesuai harapan mengingat ketersediaan layanan internet masih terbatas di beberapa wilayah Indonesia. Di Aceh, khususnya kabupaten Bireuen ketersediaan layanan internet sudah memadai untuk sebagian besar wilayah yang mana dapat dijadikan sebagai Pilot Project dari sistem yang dibangun, di samping itu sebagian besar masyarakat di wilayah Bireuen – terutama mereka yang usia produktif – memiliki gawai sebagai Daily Driver yang sangat mendukung diimplementasikannya Sistem Informasi Administrasi Desa berbasis Online.

In recent years, multi-label classifications have become common. Multi label classification is a classification in which a collection of labels is associated with a single instance, which may be a variation of the classification of a single label. The problem of huge data is the classification in which each instance is of different kind which further can be identified with more than one class. The various machine learning strategies for classifying multi-label data are discussed in this paper. Many researches have been carried out that specify the grouping of multiple labels. Here we will compare various classification machine learning techniques that involve two approaches: the adapted algorithm approach and the method of problem transformation. Here we are using naive multinomial bayes and logistic regression. We use certain evaluation metrics to predict the differences as well. Better classification methods are discussed in this paper.
A “Scientist” on the Radio: Understanding the Framing of STEM to the Public
Authors: Bowen G. Michael , Zurawski Richard , Bartley Anthony
Published: January 2021

News media presentations of STEM (and particularly science) in various formats have been critiqued for the many ways by which they misrepresent both the facts of the discipline and the practices of the discipline and the researchers in them. Another issue is that the material is presented in a format – basically a one-way transmission – with usually little opportunity for questions by the recipients (i.e., readers, listeners, viewers, etc.) to be addressed when they don’t understand something. One news media format which might allow this dialogic activity is the radio call-in show format which is structured so that the public can ask questions of a “scientist” with the opportunity for follow-up questions to address what are discontinuities in the listener’s understanding. In this paper we document the processes by which listener interests ultimately end up discussed in the radio broadcast and what influences the “science” that is presented on-air. Our analysis reports the ways in which the STEM topics and content are mediated by radio station personnel, often times distorting the factual content available to the public and misrepresenting the practices of the research fields, as they engage in information management practices which are typical of opinion-driven shows (such as those on the topics of politics or sports) which are designed to create controversy and drama to increase ratings.
Epistemological, Psychological, Neurosciences, and Cognitive Essence of Computational Thinking
Authors: Yasar Osman
Published: January 2021

The construct of computational thinking (CT) was popularized a decade ago as an “attitude and skillset” for everyone. However, since it is equated with thinking by computer scientists, the teaching of these skills poses many challenges at K-12 because of their reliance on the use of electronic computers and programming concepts that are often found too abstract and difficult by young students. This article links CT – i.e., thinking generated and facilitated by a computational device – to our typical fundamental cognitive processes by using a model of mind that is aligned with research in cognitive psychology and neuroscience and supported by a decade of empirical data on teaching and learning. Our model indicates that associative and distributive aspects of information storage, retrieval, and processing by a computational mind is the very essence of thinking, particularly deductive and inductive reasoning. We all employ these cognitive processes but not everyone uses them as iteratively, consistently, frequently, and methodologically as scientists. Some scientists have even employed electronic computing tools to boost deductive and inductive uses of their computational minds to expedite the cycle of conceptual change in their work. In this article, we offer a theoretical framework that not only describes the essence of computational thinking but also links it to scientific thinking. We recommend teaching students cognitive habits of conceptual change and reasoning prior to teaching them skills of using electronic devices. Empirical data from a five-year study involving 300 teachers and thousands of students suggests that such an approach helps improve students’ critical thinking skills as well as their motivation and readiness to learn electronic CT skills.

Objetivos: Determinar el efecto del tipo de promotor de crecimiento sobre el rendimiento productivo en pollos de engorde, bajo condiciones de trópico. Metodología: La investigación se realizó en una granja comercial de pollos de engorde ubicada en la selva central de Ucayali, Pucallpa, Provincia de Coronel Portillo. Se evaluaron 150 pollitos de un día de nacido machos de la línea Cobb 500, que fueron distribuidos al azar en tres grupos de 50 pollos, cinco réplicas y 10 pollos por réplica. Los tratamientos fueron: T0: Antibióticos, T1: Probióticos y T2: Orégano seco molido 1%. Las variables evaluadas fueron: peso vivo (PV), consumo de alimento (CA) y conversión alimenticia (ECA). Se utilizó el diseño completamente al azar, los datos se analizaron con el ANVA y para la comparación de medias, la prueba de Tukey. Resultados: Al comparar los antibióticos con los probióticos no se encontraron diferencias significativas (P > 0,05) en el PV (2,62; 2,57 kg), CA (4,75; 4,71 kg) y ECA (1,81; 1,83). El tratamiento con orégano al 1% tuvo un menor PV (2,44 kg) (P < 0,05) y similar (P > 0,05) CA (4,49 kg) y ECA (1,83) en comparación a los demás tratamientos. Conclusiones: Las dietas alimenticias con antibióticos y probióticos tuvieron un mejor rendimiento en peso vivo en comparación al 1 % de orégano.Palabras clave: Antibiótico, probiótico, orégano, pollos de engorde, promotores de crecimiento

Abstract. Nitrogen oxides (NOx = NO + NO2) play a crucial role in the formation of ozone and secondary inorganic and organic aerosols, thus affecting human health, global radiation budget, and climate. The diurnal and spatial variations of NO2 are functions of emissions, advection, deposition, vertical mixing, and chemistry. Their observations, therefore, provide useful constraints in our understanding of these factors. We employ a Regional chEmical and trAnsport model (REAM) to analyze the observed temporal (diurnal cycles) and spatial distributions of NO2 concentrations and tropospheric vertical column densities (TVCDs) using aircraft in situ measurements, surface EPA Air Quality System (AQS) observations, as well as the measurements of TVCDs by satellite instruments (OMI: the Ozone Monitoring Instrument; and GOME-2A: Global Ozone Monitoring Experiment – 2A), ground-based Pandora, and the Airborne Compact Atmospheric Mapper (ACAM) instrument, in July 2011 during the DISCOVER-AQ campaign over the Baltimore-Washington region. The model simulations at 36- and 4-km resolutions are in reasonably good agreement with the temporospatial NO2 observations in the daytime. However, nighttime mixing in the model needs to be enhanced to reproduce the observed NO2 diurnal cycle in the model. Another discrepancy is that Pandora measured NO2 TVCDs show much less variation in the late afternoon than simulated in the model. Relative to the 36-km model simulations, the 4-km model results show larger biases compared to the observations due largely to the larger spatial variations of NO2 in the model when the spatial resolution is increased from 36 to 4 km, although the biases are often comparable to the ranges of the observations. The high-resolution aircraft ACAM observations show a more dispersed distribution of NO2 vertical column densities (VCDs) and lower VCDs in urban regions than 4-km model simulations, reflecting likely the spatial distribution bias of NOx emissions in the National Emissions Inventory (NEI) 2011 at high resolution.
Observations on hygroscopic growth and phase transitions of mixed

phase separation (LLPS) dynamic process and mechanism and
secondary LLPS

Abstract. Atmospheric aerosols consisting of organic and inorganic components may undergo liquid-liquid phase separation (LLPS) and liquid-solid phase transitions during ambient relative humidity (RH) fluctuation. However, the knowledge of dynamic phase evolution processes for mixed organic-inorganic particles is scarce. Here we present a universal and visualized observation on LLPS, efflorescence and deliquescence transitions as well as hygroscopic growth of mixed 1, 2, 6-hexanetriol/ammonium sulfate (AS) particles with different organic-inorganic mole ratios (OIR = 1:4, 1:2, 1:1, 2:1 and 4:1) with the high time resolution (0.5 s), using an optical microscope with a video camera. The optical images suggest that an inner AS solution phase is surrounded by an outer organic-rich phase after LLPS for all mixed particles. The LLPS mechanism for particles with different OIRs differs, meanwhile, multiple mechanisms may dominate successively in individual particles with a certain OIR, somewhat inconsistent with earlier observations by literature. More importantly, another phase separation in inner AS solution phase, defined as secondary LLPS here, is observed for OIR = 1:1, 1:2 and 1:4 particles. The secondary LLPS may be attributed to the formation of more concentrated AS inclusions in the inner phase, and becomes more obvious with decreasing RH and increasing AS mole fraction. Furthermore, the changes in size and amount of AS inclusions during LLPS are quantitatively characterized, which further illustrate the equilibrium partitioning process of organic and inorganic components. The experimental results have significant implications for revelation of complex phase transitions of internally mixed atmospheric particles and evaluation of liquid-liquid and liquid-solid equilibria in thermodynamic models.

Abstract. We describe a new method for the measurement of U/Pb ratios by isotope dilution multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) for the dating of geologically young clean carbonates, particularly speleothems. The method is intended for materials containing little or no initial 232Th. We illustrate and validate the method with four examples ranging from 0.57 Ma to 20 Ma old. The new method is capable of applying the 235U-207 and 238U-234U-206Pb chronometers, common Pb and quantifiable residual 234U/238U disequilibrium permitting. These provide an alternative to the more widely used 238U-206Pb chronometer, which can be highly inaccurate for samples a few million years old, owing to uncertainties in the excess initial 234U (hence, excess radiogenic 206Pb) commonly observed in speleothems.

Abstract. Tree-ring δ18O values are a sensitive proxy for
regional physical climate, while their δ13C values are a strong
predictor of local ecohydrology. Utilizing available ice-core and tree-ring
δ18O records from the central Himalaya (CH), we found an
increase in east–west climate heterogeneity since the 1960s. Further,
δ13C records from transitional western glaciated valleys
provide a robust basis for reconstructing about 3 centuries of glacier
mass balance (GMB) dynamics. We reconstructed annually resolved GMB since
1743 CE based on regionally dominant tree species of diverse
plant functional types. Three major phases became apparent: positive GMB up
to the mid-19th century, the middle phase (1870–1960) of slightly
negative but stable GMB, and an exponential ice mass loss since the 1960s.
Reasons for accelerated mass loss are largely attributed to anthropogenic
climate change, including concurrent alterations in atmospheric circulations
(weakening of the westerlies and the Arabian Sea branch of the Indian summer
monsoon). Multi-decadal isotopic and climate coherency analyses specify an
eastward declining influence of the westerlies in the monsoon-dominated CH
region. Besides, our study provides a long-term context for recent GMB
variability, which is essential for its reliable projection and attribution.
